  2. Science of the subjective.

    Science.gov (United States)

    Jahn, R G; Dunne, B J

    2007-01-01

    Over the greater portion of its long scholarly history, the particular form of human observation, reasoning, and technical deployment we properly term "science" has relied at least as much on subjective experience and inspiration as it has on objective experiments and theories. Only over the past few centuries has subjectivity been progressively excluded from the practice of science, leaving an essentially secular analytical paradigm. Quite recently, however, a compounding constellation of newly inexplicable physical evidence, coupled with a growing scholarly interest in the nature and capability of human consciousness, are beginning to suggest that this sterilization of science may have been excessive and could ultimately limit its epistemological reach and cultural relevance. In particular, an array of demonstrable consciousness-related anomalous physical phenomena, a persistent pattern of biological and medical anomalies, systematic studies of mind/brain relationships and the mechanics of human creativity, and a burgeoning catalogue of human factors effects within contemporary information processing technologies, all display empirical correlations with subjective aspects that greatly complicate, and in many cases preclude, their comprehension on strictly objective grounds. However, any disciplined re-admission of subjective elements into rigorous scientific methodology will hinge on the precision with which they can be defined, measured, and represented, and on the resilience of established scientific techniques to their inclusion. For example, any neo-subjective science, while retaining the logical rigor, empirical/theoretical dialogue, and cultural purpose of its rigidly objective predecessor, would have the following requirements: acknowledgment of a proactive role for human consciousness; more explicit and profound use of interdisciplinary metaphors; more generous interpretations of measurability, replicability, and resonance; a reduction of ontological

    Two independent studies were conducted to extend previous research by examining the associations between task value priority patterns across school subjects and aspirations toward the physical and information technology- (IT-) related sciences. Study 1 measured task values of a sample of 10th graders in the United States (N = 249) across (a) physics and chemistry, (b) math, and (c) English. Study 2 measured task values of a sample of students in the second year of high school in Finland (N = 351) across (a) math and science, (b) Finnish, and (c) the arts and physical education. In both studies, students were classified into groups according to how they ranked math and science in relation to the other subjects. Regression analyses indicated that task value group membership significantly predicted subsequent aspirations toward physical and IT-related sciences measured 1-2 years later. The task value groups who placed the highest priority on math and science were significantly more likely to aspire to physical and IT-related sciences than were the other groups. These findings provide support for the theoretical assumption regarding the predictive role of intraindividual hierarchical patterns of task values for subsequent preferences and choices suggested by the Eccles [Parsons] (1983) expectancy-value model.

  4. Schools That Make a Difference to Post-Compulsory Uptake of Physical Science Subjects: Some comparative case studies in England

    Bennett, Judith; Lubben, Fred; Hampden-Thompson, Gillian

    2013-03-01

    This paper presents the findings of the qualitative component of a combined methods research study that explores a range of individual and school factors that influence the uptake of chemistry and physics in post-compulsory study in England. The first phase involves using the National Pupil Database to provide a sampling frame to identify four matched pairs of high-uptake and low-uptake schools by salient school factors. Case studies of these eight schools indicate that students employ selection strategies related to their career aspirations, their sense of identity and tactics, and their prior experience. The school factors influencing subject choice relate to school management, student support and guidance, and student empowerment. The most notable differences between students in high-uptake and low-uptake schools are that students in high-uptake schools appear to make a proactive choice in relation to career aspirations, rather than a reactive choice on the basis of past experience. Schools with a high uptake offer a diverse science curriculum in the final two years of compulsory study, set higher examination entry requirements for further study and, crucially, provide a range of opportunities for students to interact with the world of work and to gain knowledge and experience of science-related careers.

  5. Teaching physics as a service subject

    Science.gov (United States)

    Lowe, T. L.; Hayes, M.

    1986-07-01

    At South Glamorgan Institute of Higher Education physics is taught over a wide range of courses. In addition to the more conventional courses found in science, technology and education faculties there is a physics input into areas such as beauty therapy, applied biology, catering, chiropody, dental technology, environmental health, food technology, hairdressing, human-movement studies, industrial design, applied life sciences, marine technology, medical laboratory science, physiological measurement, nursing and speech therapy. Due to the fundamental differences in emphasis required when teaching physics as a 'minor' subject on these types of courses, and since the authors have no courses which lead to a 'major' physics qualification, it is necessary to develop a rational strategy for teaching physics as a 'service' subject. If this is not achieved then staff satisfaction and student interest are likely to suffer. They describe their strategy.

    Sérgio Choiti Yamazaki

    2015-12-01

    Full Text Available This paper presents the results of a survey conducted in a public university in the country, which aimed to identify the presence elements ordinarily related to subjective phenomena, in the works published in National Symposium of Physics Education, an event that provides meeting between teachers, researchers and students from around the country. The elements to which we have referred are found in contemporary didactic and pedagogical proposals, because it is identified that purely cognitive or even cultural rights are not sufficient to understand the phenomena that happen in the classroom, or more broadly, in education as a whole. The analysis contemplated the publications of the past 3 symposia, and the results infer a small increase of citations of these elements. However, this growth must be questioned because the quotes are made in isolation, not being taken to support the analysis of the authors. In addition, this research also shows that the presence of these elements is very small compared with the total number of papers published in the events.

  13. Feminist Physics Education: Deconstructed Physics and Students' Multiple Subjectivities

    Science.gov (United States)

    Jammula, Diane Crenshaw

    Physics is one of the least diverse sciences; in the U.S. in 2010, only 21% of bachelors degrees in physics were awarded to women, 2.5% to African Americans, and 4% to Hispanic Americans (AIP, 2012). Though physics education reform efforts supporting interactive engagement have doubled students' learning gains (Hake, 1998), gender and race gaps persist (Brewe et al., 2010; Kost, Pollock, & Finkelstein, 2009). When students' subjectivities align with presentations of physics, they are more likely to develop positive physics identities (Hughes, 2001). However, both traditional and reformed physics classrooms may present physics singularly as abstract, elite, and rational (Carlone, 2004). Drawing from feminist science, I argue that binaries including abstract / concrete, elite / accessible, and rational / emotional are hierarchal and gendered, raced and classed. The words on the left define conventional physics and are associated with middle class white masculinity, while the words on the right are associated with femininity or other, and are often missing or delegitimized in physics education, as are females and minorities. To conceptualize a feminist physics education, I deconstructed these binaries by including the words on the right as part of doing physics. I do not imply that women and men think differently, but that broadening notions of physics may allow a wider range of students to connect with the discipline. I used this conceptual framework to modify a popular reformed physics curriculum called Modeling Instruction (Hestenes, 1987). I taught this curriculum at an urban public college in an introductory physics course for non-science majors. Twenty-three students of diverse gender, race, ethnic, immigrant and class backgrounds enrolled. I conducted an ethnography of the classroom to learn how students negotiate their subjectivities to affiliate with or alienate from their perceptions of physics, and to understand how classroom experiences exacerbate or

    Teodorani, M.

    1999-03-01

    The psycho-sociological reasons why the academic science is not willing to face operatively and officially a hard problem such as the 'UFO phenomenon', are introduced in the ambit of an episthemological discussion. It is shown how such a phenomenon, due to his peculiar nature, might impose a drastic revision of the laws of physics which are commonly accepted. It is demonstrated how a strict application of the measurement methods which are normally adopted by physics can permit to obtain relevant quantitative results, whatever they are. As an example of such a procedure, the anomalous light phenomenology which reoccurs in the Hessdalen valley in Norway is presented, by showing that it represents so far the ideal worldly physical laboratory for the study of luminous phenomena in the low atmosphere. After describing the multiform morphologic and dynamic characteristics of the luminous component of the phenomenon as they are deduced from visual and photographic reports, the results coming out from the magnetometric, radiometric and radar monitoring operations which were carried out by Project Hessdalen in 1984, are presented in detail. Subsequently, the postumous analysis carried out by the author is shown, by pointing out the clear cohexistence of the magnetic and the optical phenomenology and the apparent correlation of the magnetic component of the phenomenon with maxima of solar activity. In a subsequent phase, the most credited physical theories, which have been proposed so far in order to interpret the phenomenon, are described and discussed, together with 'non-canonical hypotheses'. Finally, it is pointed out how the physical parameters which are expected to be measured with the proper instrumented equipment and aimed tactics and strategies, resemble strictly the methodology which is normally used during astrophysical observations.

    Biological physics is clearly becoming one of the leading sciences of the 21st century. This field involves the cross-fertilization of ideas and methods from biology and biochemistry on the one hand and the physics of complex and far from equilibrium systems on the other. Here I want to discuss how biological physics is a new area of physics and not simply applications of known physics to biological problems. I will focus in particular on the new advances in theoretical physics that are already flourishing today. They will become central pieces in the creation of this new frontier of science.

  20. [What is the subject of science "bioinformatics"?].

    Science.gov (United States)

    Chaĭlakhian, L M

    2005-01-01

    The paper is concerned with some problems of terminology, in particular the term "bioinformatics". In the last few years, the term "bioinformatics" has been intensively used among molecular biologists to indicate a subject that is only a constituent of genomics and is considered to involve a computer-assisted analysis of all data on nucleotide sequences of DNA. However, a wide circle of scientists, including biologists, physicists, mathematicians, and specialists in the field of cybernetics, informatics, and other disciplines have accepted and accept, as a rule, the "bioinformatics" as a synonym of science cybernetics and as a successor of this science. In this case, the subject of science "bioinformatics" should embrace not only genomics but practically all sections of the biological science. It should involve a study of information processes (storage, transfer, and processing of information, etc.) participating in the regulation and control at all levels of living systems, from macromolecules to the brain of higher animals and human.

    2008-01-01

    Originally developed for the author's course at Union College, this text is designed for life science students who need to understand the connections of fundamental physics to modern biology and medicine. Almost all areas of modern life sciences integrally involve physics in both experimental techniques and in basic understanding of structure and function. Physics of the Life Sciences is not a watered-down, algebra-based engineering physics book with sections on relevant biomedical topics added as an afterthought. This authoritative and engaging text, which is designed to be covered in a two-semester course, was written with a thoroughgoing commitment to the needs and interests of life science students. Although covering most of the standard topics in introductory physics in a more or less traditional sequence, the author gives added weight and space to concepts and applications of greater relevance to the life sciences. Students benefit from occasional sidebars using calculus to derive fundamental relations,...

    To determine the level of importance pharmacy students placed on science and mathematics subjects for pursuing a career in pharmacy. Two hundred fifty-four students completed a survey instrument developed to investigate students' perceptions of the relevance of science and mathematics subjects to a career in pharmacy. Pharmacy students in all 4 years of a master of pharmacy (MPharm) degree program were invited to complete the survey instrument. Students viewed chemistry-based and biology-based subjects as relevant to a pharmacy career, whereas mathematics subjects such as physics, logarithms, statistics, and algebra were not viewed important to a career in pharmacy. Students' experience in pharmacy and year of study influenced their perceptions of subjects relevant to a pharmacy career. Pharmacy educators need to consider how they can help students recognize the importance of scientific knowledge earlier in the pharmacy curriculum.

    2015-06-01

    Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

    Limited exercise tolerance is a cardinal clinical feature in COPD. Depression and COPD share some clinical features, such as reduced physical activity and impaired nutritional status. The aim of the present study was to evaluate maximum and daily physical activities and the nutritional status of COPD patients affected or not by depression. In 70 COPD out-patients, daily and maximum physical activities were assessed by multisensor accelerometer armband, 6-min walk test, and cardiopulmonary exercise test. Mental status, metabolic/muscular status, and systemic inflammation were evaluated using the Hospital Anxiety and Depression Scale, by bioelectrical impedance analysis, and with regard to fibrinogen/C-reactive protein, respectively. Depressed subjects (27% of the sample) showed a similar level of respiratory functional impairment but a higher level of shortness of breath and a worse quality of life compared to non-depressed subjects (P physical activity impairment consisting of a reduced number of steps per day, a lower peak of oxygen consumption, an early anaerobic threshold, and a reduced distance in the 6-min walk test (P daily number of steps. Our study found that depressed COPD patients have a reduced daily and maximum exercise capacity compared to non-depressed patients. This further suggests the potential utility of screening for depression in COPD.

    interest in science and current scientific research. The goals of "Physics On Stage 3" [EWST Logo] "Physics on Stage 3" also aims to facilitate the exchange of good practice and innovative ideas among Europe's science teachers and to provide a forum for a broad debate among educators, administrators and policy-makers about the key problems in science education today. Moreover, it will make available the considerable, combined expertise of the EIROforum organisations to the European scientific teaching community, in order to promote the introduction of "fresh" science into the curricula and thus to convey a more realistic image of modern science to the pupils. "Physics on Stage 3" is concerned with basic science and also with the cross-over between different science disciplines - a trend becoming more and more important in today's science, which is not normally reflected in school curricula. A key element of the programme is to give teachers an up-to-date "insiders'" view of what is happening in science and to tell them about new, highly-diverse and interesting career opportunities for their pupils. Theme of the activities The theme of "Physics on Stage" this year is "Physics and Life" , reflecting the decision to broaden the Physics on Stage activities to encompass all the natural sciences. Including other sciences will augment the already successful concept, introducing a mixture of cross-over projects that highlight the multidisciplinary aspects of modern science. Among the many subjects to be presented are radiation, physics and the environment, astrobiology (the search for life beyond earth), complex systems, self-organising systems, sports science, the medical applications of physics, mathematics and epidemiology, etc. The main elements National activities "Physics on Stage 3" has already started and National Steering Committees in 22 countries, composed of eminent science teachers, scientists, administrators and others involved in setting school curricula, are now

    2012-02-01

    Full Text Available Physical aspects of medical science involve making physical models, physical approaches, and measurements by physical instruments. Among these, the physical approach is the most important for an exact elucidation of the physiological function of living materials. What is a physical approach? In the first step, the molecular mechanism of visual transduction will be demonstrated by considering the physical characteristics of diffusion of second messengers. In the next step, I will consider how frequency modulation–type impulse signaling is converted from amplitude modulation–type electric signaling. In the last section, I will discuss how impulse signaling (i.e., the train of action potentials is processed by the neural network in the brain and eventually is recognized in the frontal cortex using near infrared spectroscopy. In order to obtain such a physical model of vision, many physical concepts are used, such as light reflex, energy transduction, diffusion of molecules, threshold, the Coulomb interaction, light absorption, and cluster analysis. Among them, the Coulomb interaction, light absorption, and diffusion of molecules are three essential keywords for the physical process.

    Gottstein, Günter

    2004-01-01

    In this vivid and comprehensible introduction to materials science, the author expands the modern concepts of metal physics to formulate basic theory applicable to other engineering materials, such as ceramics and polymers. Written for engineering students and working engineers with little previous knowledge of solid-state physics, this textbook enables the reader to study more specialized and fundamental literature of materials science. Dozens of illustrative photographs, many of them Transmission Electron Microscopy images, plus line drawings, aid developing a firm appreciation of this complex topic. Hard-to-grasp terms such as "textures" are lucidly explained - not only the phenomenon itself, but also its consequences for the material properties. This excellent book makes materials science more transparent.

    Boyack, Kevin W.

    1999-07-02

    Various efforts to map the structure of science have been undertaken over the years. Using a new tool, VxInsight{trademark}, we have mapped and displayed 3000 journals in the physical sciences. This map is navigable and interactively reveals the structure of science at many different levels. Science mapping studies are typically focused at either the macro-or micro-level. At a macro-level such studies seek to determine the basic structural units of science and their interrelationships. The majority of studies are performed at the discipline or specialty level, and seek to inform science policy and technical decision makers. Studies at both levels probe the dynamic nature of science, and the implications of the changes. A variety of databases and methods have been used for these studies. Primary among databases are the citation indices (SCI and SSCI) from the Institute for Scientific Information, which have gained widespread acceptance for bibliometric studies. Maps are most often based on computed similarities between journal articles (co-citation), keywords or topics (co-occurrence or co-classification), or journals (journal-journal citation counts). Once the similarity matrix is defined, algorithms are used to cluster the data.

    Light, L

    1949-01-01

    Some years' experience in teaching Russian to working scientists who had already acquired the rudiments of the grammar convinced me of the need for a reader of the present type that would smooth the path of those wishing to study Russian scientific literature in the original. Although the subject matter comprises what I have described for convenience as chemistry, physics and biology, it could be read with equal profit by those engaged in any branch of pure or applied science. All the passages are taken from school textbooks, and acknowledgements are due to the authors of the works listed at the foot of the contents page.

  18. Piaget's epistemic subject and science education: Epistemological vs. psychological issues

    Science.gov (United States)

    Kitchener, Richard F.

    1993-06-01

    Many individuals claim that Piaget's theory of cognitive development is empirically false or substantially disconfirmed by empirical research. Although there is substance to such a claim, any such conclusion must address three increasingly problematic issues about the possibility of providing an empirical test of Piaget's genetic epistemology: (1) the empirical underdetermination of theory by empirical evidence, (2) the empirical difficulty of testing competence-type explanations, and (3) the difficulty of empirically testing epistemic norms. This is especially true of a central epistemic construct in Piaget's theory — the epistemic subject. To illustrate how similar problems of empirical testability arise in the physical sciences, I briefly examine the case of Galileo and the correlative difficulty of empirically testing Galileo's laws. I then point out some important epistemological similarities between Galileo and Piaget together with correlative changes needed in science studies methodology. I conclude that many psychologists and science educators have failed to appreciate the difficulty of falsifying Piaget's theory because they have tacitly adopted a philosophy of science at odds with the paradigm-case of Galileo.

    2015-11-01

    This article briefly reviews the biofield hypothesis and its scientific literature. Evidence for the existence of the biofield now exists, and current theoretical foundations are now being developed. A review of the biofield and related topics from the perspective of physical science is needed to identify a common body of knowledge and evaluate possible underlying principles of origin of the biofield. The properties of such a field could be based on electromagnetic fields, coherent states, biophotons, quantum and quantum-like processes, and ultimately the quantum vacuum. Given this evidence, we intend to inquire and discuss how the existence of the biofield challenges reductionist approaches and presents its own challenges regarding the origin and source of the biofield, the specific evidence for its existence, its relation to biology, and last but not least, how it may inform an integrated understanding of consciousness and the living universe.

    Full Text Available Physical Education has its own definition inside the system of anthropomorphological sciences. But, there is a question whether it is possible to explain the phenomenon of physical education only inside of the system of abstrct atitudes based on an objective observation of reality or it is (at least some of its parts are an activity which has for an object the stimulation of human senses, mind or spirit. In this essey we discuss, in a very subjective way, the matter which concerns the culture in order to define the position of physical education inside the art system. The word "art" can relate to the variety of subjects, feelings or activities. Because of it, the fragments of art can be defined as creative interpretations of indefinite concepts or ideas. Having in mind the fact that in a world of art it is not possible to define standards that determine the art itself, according to the criteria which are generally accepted, it is still possible to make connection between sport and art by some rational observation. This work can enter the history thanks to the initiative to accept the sport as an aspect of art

This research places inside the methodology of quantitative type of descriptive cut, across survey, which has been in use as instrument of withdrawal of information the interview standardized by means of questionnaire created ad hoc, that was completed by 300 teachers. In the study there is obtained that the vast majority of the teachers who give classes in the extracurricular physical activities say they do not establish any coordination with the Physical Education teacher of the school. However, most of these teachers feel they would be good if there were a coordination with the teachers of Physical Education. However, more than half of teachers who give classes in the extracurricular physical activities believe that the objectives of the activities they provide are not related to the objectives of the Physical Education.

    2017-11-01

    Full Text Available This study explored the physical activities of fifth and sixth graders that projected correlations to science performance and how these physical activities may be utilized for classroom purposes in the context of science-related play activities. Descriptive survey correlational design directed the data collection and analysis of the physical activities of purposively selected 133 fifth and sixth graders. Primarily, the study used a researcher-developed and validated instrument (Physical Activity Questionnaire [PAQ], and standard instruments: Philippine National Physical Activity Guide (PNPAG and General Physical Activity Questionnaire (GPAQ. The latter classified the physical activities into five domains which directed the interpretation of the participants‟ responses. The Pearson-r Moment of Correlation described the level of correlation of the frequency of engagement to physical activities (limited to local and localized activities and the science grade of the respondents. Results show that each of the physical activity domains showed specific correlations to science performance of the respondents. For further research, enrichment of the relationship of the physical activities and the science performance may focus on possible moderating variables like economic status, and time allotment for physical activities.

    Horváthová, Daniela; Rakovská, Mária; Zelenický, Ľubomír

    2017-01-01

    Terms - project, projecting and the method of projecting - are nowadays frequently used in different relations. Those terms, especially as methods (of a cognitive process), are also transferred to the educational process. Before a new educational method comes to practice, the teacher should be familiar with it and preferably when it is done so during his university studies. An optional subject called Physics in a system of science subjects has been included into physics curricula for students of the fourth year of their studies at the Faculty of Science of Constantine the Philosopher University in Nitra. Its task is to make students aware of ways how to coordinate knowledge and instructions presented in these subjects through analysis of curricula and textbooks. As a part of their seminars students are asked to create integrated tasks and experiments which can be assessed from the point of view of either physics or chemistry or biology and which can motivate pupils and form their complex view on various phenomena in the nature. Therefore the article discusses theoretical and also practical questions related to experience that originates from placing the mentioned method and the subject Physics in a system of science subjects into the preparation of a natural sciences teacher in our workplace.

    In order for regulators to create successful policies on technical issues, ranging from environmental protection to distribution of national Grant money, the scientific community must play an integral role in the legislative process. Through a summer-long internship with the Science, Space, and Technology Committee of the U.S. House of Representatives, I have learned that skills developed while pursuing an undergraduate degree in physics are very valuable in the policy realm. My physics education provided me the necessary tools to bridge the goals of the scientific and political communities. The need for effective comprehension and communication of technical subjects provides an important opportunity for individuals with physics degrees to make substantial contributions to government policy. Science policy should be encouraged as one of the many career pathways for physics students. Society of Physics Students, John and Jane Mather Foundation for Science and the Arts.

    2017-12-01

    Fostering and maintaining students' interest in science is an important aspect of improving science learning. The focus of this paper is to listen to and reflect on students' voices regarding the sources of motivation for science subjects among students in community secondary schools with contextual challenges in Tanzania. We conducted a group-interview study of 46 Form 3 and Form 4 Tanzanian secondary school students. The study findings reveal that the major contextual challenges to student motivation for science in the studied schools are limited resources and students' insufficient competence in the language of instruction. Our results also reveal ways to enhance student motivation for science in schools with contextual challenges; these techniques include the use of questioning techniques and discourse, students' investigations and practical work using locally available materials, study tours, more integration of classroom science into students' daily lives and the use of real-life examples in science teaching. Also we noted that students' contemporary life, culture and familiar language can be utilised as a useful resource in facilitating meaningful learning in science in the school. Students suggested that, to make science interesting to a majority of students in a Tanzanian context, science education needs to be inclusive of students' experiences, culture and contemporary daily lives. Also, science teaching and learning in the classroom need to involve learners' voices.

  14. Walking With Meaning: Subjective Experiences of Physical Activity in Dementia.

    Science.gov (United States)

    McDuff, Jennifer; Phinney, Alison

    2015-01-01

    Physical activity is beneficial for people with dementia, but little research explores subjective experiences of physical activity in this population. Interpretive description guided the analysis of 26 interviews conducted with 12 people with dementia. Three themes described the subjective meaning of everyday physical activity: Participants were attracted to activity because it improved physical well-being, provided social connections, gave opportunity to be in nature, and provided structure and focus; participants experienced impediments to activity because of physical discomfort, environmental factors, lack of enthusiasm, and memory loss; and participants made adjustments by choosing walking over other activities and by being active with others. Results show that physical activity remains important for people with dementia, although they encounter barriers. They may prefer walking with others as a form of activity. Findings could influence how nurses conceptualize wandering and suggest that walking programs could be well received by people with dementia.

    Full Text Available 'Cyberpunk’ science fiction is a self-proclaimed movement within the genre which began in the 1980s. As the name suggests, it is an extrapolative form of science fiction which combines an almost obsessional interest in machines (particularly information machines with an anarchic, amoral, streetwise sensibility This paper sketches the development of the movement and seeks to make qualified claims for the radical. potential of its fiction. Of crucial importance are the ways in which human subjectivity (viewed in psychoanalytic terms interacts with 'technological subjectivity' in cyberpunk, particularly with regard to implications of these interactions for oedipalization.

    2011-12-01

    The use of cyclotrons and synchrotrons to accelerate charged particles in hospital settings for the purpose of cancer therapy is increasing. Consequently, there is a growing demand from medical physicists, radiographers, physicians and oncologists for articles that explain the basic physical concepts of these technologies. There are unique advantages and disadvantages to all methods of acceleration. Several promising alternative methods of accelerating particles also have to be considered since they will become increasingly available with time; however, there are still many technical problems with these that require solving. This article serves as an introduction to this complex area of physics, and will be of benefit to those engaged in cancer therapy, or who intend to acquire such technologies in the future.

  20. PHYSICAL SCIENCE TEACHERS’ PERCEPTIONS OF AN ADVANCED CERTIFICATE IN EDUCATION

    Directory of Open Access Journals (Sweden)

    Sarah Bansilal

    2016-04-01

    Full Text Available Advanced Certificate in Education programmes was offered by many South African universities to provide opportunities for teachers to upgrade their positions. The purpose of the study was to explore Physical Science teachers’ perceptions of their professional development. In this study we considered three domains of professional development which are content knowledge, pedagogic content knowledge and teacher beliefs and attitudes. This study used a mixed method approach using the form of an embedded design. The study was conducted with 156 students enrolled in an ACE Physical Science programme. The teachers stated that their content knowledge and pedagogic content knowledge had not only improved, but also their engagement with actual laboratories, and conducting experiments contributed to their teaching experiences. Hence, their self-confidence of physical science teaching evolved. The authors recommend that the ACE programme should also include a mentoring system with teaching practicum via school leadership and subject advisers.

  3. Research Misconduct and the Physical Sciences

    Energy Technology Data Exchange (ETDEWEB)

    HM Kerch; JJ Dooley

    1999-10-11

    Research misconduct includes the fabrication, falsification, and plagiarism (FFP) of concepts or ideas; some institutions have expanded this concept to include ''other serious deviations (OSD) from accepted research practice.'' An action can be evaluated as research misconduct if it involves activities unique to the practice of science and could negatively affect the scientific record. Although the number of cases of research misconduct is uncertain (formal records are kept only by the NIH and the NSF), the costs are high in integrity of the scientific record, diversions from research to investigate allegations, ruined careers of those eventually exonerated, and erosion of public confidence in science. Currently, research misconduct policies vary from institution to institution and from government agency to government agency; some have highly developed guidelines that include OSD, others have no guidelines at ail. One result has been that the federal False Claims Act has been used to pursue allegations of research misconduct and have them adjudicated in the federal court, rather than being judged by scientific peers. The federal government will soon establish a first-ever research misconduct policy that would apply to all research funded by the federal government regardless of what agency funded the research or whether the research was carried out in a government, industrial or university laboratory. Physical scientists, who up to now have only infrequently been the subject or research misconduct allegations, must none-the-less become active in the debate over research misconduct policies and how they are implemented since they will now be explicitly covered by this new federal wide policy.

    It is critically important that national and international science policy be scientifically grounded. To this end, the next generation of scientists and engineers will need to be technically competent, effective communicators of science, and engaged advisors in the debate and formulation of science policy. We describe three science policy debates developed for the physics classroom aimed at encouraging students to draw connections between their developing technical expertise and important science policy issues. The first debate considers the proposal for a 450-megawatt wind farm on public lands in Nantucket Sound and fits naturally into the curriculum related to alternative forms of energy production. The second debate considers national fuel-economy standards for sport-utility vehicles and can be incorporated into the curriculum related to heat engines. The third debate, suitable for the curriculum in optics, considers solid state lighting and implications of recent United States legislation that places stringent new energy-efficiency and reliability requirements on conventional lighting. The technical foundation for each of these debates fits naturally into the undergraduate physics curriculum and the material is suitable for a wide range of physics courses, including general science courses for non-majors.

  6. Biopolitics and the `subject' of labor in science education

    2017-12-01

    Viewing science education as a site of biopolitical engagement—intervention into forces that seek to define, control, and exploit life (biopower)—requires that science educators ask after how individuals and populations are governed by technologies of power. In this paper, I argue that microanalyses, the analysis of everyday practices and discourses, are integral to biopolitical engagement, are needed to examine practices that constitute subjectivities and maintain oppressive social conditions. As an example of a microanalysis I will discuss how repetitive close-ended lab/assessment tasks, as well as discourses surrounding careers in science, can work to constitute students as depoliticized, self-investing subjects of human capital. I also explore the relationship between science education, (bio)labor and its relation to biopolitics, which remains an underdeveloped area of science education. This paper, part of my doctoral work, began to take shape in 2011, shortly after the 2008 economic crisis achieved a tiny breached in the thick neoliberal stupor of everyday (educational) life.

  8. Beyond Objectivity and Subjectivity: The Intersubjective Foundations of Psychological Science.

    Science.gov (United States)

    Mascolo, Michael F

    2016-12-01

    The question of whether psychology can properly be regarded as a science has long been debated (Smedslund in Integrative Psychological & Behavioral Science, 50, 185-195, 2016). Science is typically understood as a method for producing reliable knowledge by testing falsifiable claims against objective evidence. Psychological phenomena, however, are traditionally taken to be "subjective" and hidden from view. To the extent that science relies upon objective observation, is a scientific psychology possible? In this paper, I argue that scientific psychology does not much fail to meet the requirements of objectivity as much as the concept of objectivity fails as a methodological principle for psychological science. The traditional notion of objectivity relies upon the distinction between a public, observable exterior and a private, subjective interior. There are good reasons, however, to reject this dichotomy. Scholarship suggests that psychological knowledge arises neither from the "inside out" (subjectively) nor from the outside-in (objectively), but instead intersubjective processes that occur between people. If this is so, then objectivist methodology may do more to obscure than illuminate our understanding of psychological functioning. From this view, we face a dilemma: Do we, in the name of science, cling to an objective epistemology that cuts us off from the richness of psychological activity? Or do we seek to develop a rigorous intersubjective psychology that exploits the processes through which we gain psychological knowledge in the first place? If such a psychology can produce systematic, reliable and useful knowledge, then the question of whether its practices are "scientific" in the traditional sense would become irrelevant.

  9. A Comparative Study of the Empirical Relationship in Student Performance between Physics and Other STEM Subjects

    Guerra, Maricela

    The Next Generation Science Standards (NGSS) advocated by the National Research Council emphasize the connections among Science, Technology, Engineering, and Mathematics (STEM) disciplines. By design, NGSS is expected to replace the previous science education standards to enhance the quality of STEM education across the nation. To support this initiative, this investigation was conducted to fill a void in the research literature by developing an empirical indicator for the relationship of student performance across STEM subjects using a large-scale database from the Trends in Mathematics and Science Study (TIMSS). In particular, an innovative approach has been taken in this study to support the canonical correlation analysis of student plausible scores between physics and other STEM subjects at different grade levels and in a cross-country context. Results from this doctoral research revealed the need to strengthen the alignment between the intended, implemented, and attained curricula to support the integration of STEM disciplines in the United States.

  12. A Science Strategy for Space Physics

    Science.gov (United States)

    1995-01-01

    This report by the Committee on Solar and Space Physics and the Committee on Solar-Terrestrial Research recommends the major directions for scientific research in space physics for the coming decade. As a field of science, space physics has passed through the stage of simply looking to see what is out beyond Earth's atmosphere. It has become a 'hard' science, focusing on understanding the fundamental interactions between charged particles, electromagnetic fields, and gases in the natural laboratory consisting of the galaxy, the Sun, the heliosphere, and planetary magnetospheres, ionospheres, and upper atmospheres. The motivation for space physics research goes far beyond basic physics and intellectual curiosity, however, because long-term variations in the brightness of the Sun virtually affect the habitability of the Earth, while sudden rearrangements of magnetic fields above the solar surface can have profound effects on the delicate balance of the forces that shape our environment in space and on the human technology that is sensitive to that balance. The several subfields of space physics share the following objectives: to understand the fundamental laws or processes of nature as they apply to space plasmas and rarefied gases both on the microscale and in the larger complex systems that constitute the domain of space physics; to understand the links between changes in the Sun and the resulting effects at the Earth, with the eventual goal of predicting the significant effects on the terrestrial environment; and to continue the exploration and description of the plasmas and rarefied gases in the solar system.

  13. Linking Science Fiction and Physics Courses

    Generally, cohorts or learning communities enrich higher learning in students. Learning communities consist of conventionally separate groups of students that meet together with common academic purposes and goals. Types of learning communities include paired courses with concurrent student enrollment, living-learning communities, and faculty learning communities. This article discusses a learning community of 21 students that I created with a colleague in the English department. The community encompasses two general education courses: an algebra-based physics course entitled "Intro to Physics" and a literature course entitled "Science Fiction, Science Fact." Students must enroll in both of these courses during the same semester. Additionally, I highlight advantages to linking these courses through surveying the assignments and course materials that we used in our learning community. Figure 1 shows the topics that are covered in both physics and literature courses.

    Obesity in children and young adult is associated with cardiovascular risk in short term and long term. The aim of this study was to describe the profile of the cardiovascular functions parameters and physical fitness in overweight. This is an analytical observational study with cross sectional approach. The samples of this study were 85 randomly selected subjects aged 18 to 24 years with normoweight and body mass index parameters measures were body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), cardiovascular function parameters (resting pulse, blood pressure, and peak flow meter) and physical fitness parameters (VO2max dengan McArdle step test). The mean BMI was 24,53±4,929. The WC and WHR mean were 86,7±14,10 cms and 0,89±0,073 cm respectively. The mean of resting pulses were higher in normoweight subject (p=0,0209). The mean systole were lower in normoweight subject (p=0,0026). No differences VO2 max between groups (p=0,3888). The peak flow meter was higher in normoweight (p=0,0274). The result of this study indicate that heart rate, systole and peak flow meter are signifantly different between groups. The heart rate and the peak flow meter in the overweight subjects were lower meanwhile the systole blood pressure was higher compared to normoweight subjects.

  15. Enhancing interdisciplinary, mathematics, and physical science in an undergraduate life science program through physical chemistry.

    Pursell, David P

    2009-01-01

    BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of the undergraduate biology curriculum. The Department of Chemistry and Life Science at West Point responded by developing a required physical chemistry course tailored to the interests of life science majors. To overcome student resistance to physical chemistry, students were enabled as long-term stakeholders who would shape the syllabus by selecting life science topics of interest to them. The initial 2 yr of assessment indicates that students have a positive view of the course, feel they have succeeded in achieving course outcome goals, and that the course is relevant to their professional future. Instructor assessment of student outcome goal achievement via performance on exams and labs is comparable to that of students in traditional physical chemistry courses. Perhaps more noteworthy, both student and instructor assessment indicate positive trends from year 1 to year 2, presumably due to the student stakeholder effect.

    Full Text Available Considering the influence of new agency forms - intervention and interaction among subjects - in the context of information intermediation, we aim to approach information actions in Science and Technology (S&T taking into consideration the institutionalities involved. For such, we assume there is an influence of a theoretical model emerging in Information Science (IS regarding current inventive and interactive form propitiated by the Web. The text is structured in two central topics bringing: i theoretical and epistemic constructions of the "information action" concept; and ii a certain interpretation oriented by the "informational action in S&T" construct, taking as its object the actions performed by IBICT (Brazilian Institute for Information in Science and Technology, directed towards excellence in information. Finally, we discuss how limitations of the "systemic model" propitiate the construction of new study objects in the model emerging in IS from theoretical innovations and counterpoints thoughts facing the diverse forms of information action, considering, for instance, the action of subjects on what concerns the validation of information in the current scenery of institutional intermediation.

    Watson, Erin M

    2005-10-01

    This study investigated whether Canadian academic health sciences librarians found knowledge of the health sciences to be important and, if so, how they acquired and maintained this knowledge. Data were gathered using a Web-based questionnaire made available to Canadian academic health sciences librarians. Respondents recognized the need for subject knowledge: 93.3% of respondents indicated that subject knowledge was "very important" or "somewhat important" to doing their job. However, few respondents felt that holding a degree in the health sciences was necessary. Respondents reported devoting on average more than 6 hours per week to continuing education through various means. Reading or browsing health sciences journals, visiting Websites, studying independently, and participating in professional associations were identified by the largest number of participants as the best ways to become and stay informed. Although more research needs to be done with a larger sample, subject knowledge continues to be important to Canadian academic health sciences librarians. Continuing education, rather than formal degree studies, is the method of choice for obtaining and maintaining this knowledge.

    2013-05-26

    The aim of this study was to identify dietary strategies for physically active individuals with muscle dysmorphia based on a systematic literature review. References were included if the study population consisted of adults over 18 years old who were physically active in fitness centers. We identified reports through an electronic search ofScielo, Lilacs and Medline using the following keywords: muscle dysmorphia, vigorexia, distorted body image, and exercise. We found eight articles in Scielo, 17 in Medline and 12 in Lilacs. Among the total number of 37 articles, only 17 were eligible for inclusion in this review. The results indicated that the feeding strategies used by physically active individuals with muscle dysmorphia did not include planning or the supervision of a nutritionist. Diet included high protein and low fat foods and the ingestion of dietary and ergogenic supplements to reduce weight. Physically active subjects with muscle dysmorphia could benefit from the help of nutritional professionals to evaluate energy estimation, guide the diet and its distribution in macronutrient and consider the principle of nutrition to functional recovery of the digestive process, promote liver detoxification, balance and guide to organic adequate intake of supplemental nutrients and other substances.

    Marcellini, Anne; Perera, Éric; Rodhain, Angélique; Férez, Sylvain

    2016-06-08

    From a sociological perspective, physical activity and diet are perceived as social and cultural practices, constructed and transmitted within human societies. The body is then thought of as a social construct, a sign and foundation of individual and collective identities. In this context, this article was designed to highlight some social processes underlying the obesity epidemic. Clarifying issues about a medical definition of obesity in an obesogenic society, and theoretical approaches to the meanings of the obesity epidemic are proposed. Individual stories of a gradual shift towards obesity are presented to illustrate the variety of trajectories that can lead to obesity in adulthood but also the variety of subjective experiences about the situation of obesity. In particular, the relationship to the body and experiences in terms of physical activity are investigated in order to understand how obesity is associated with non-commitment, low commitment or abandonment of physical activity. The issue of configurations in which commitment or re-commitments in regular exercise for sedentary populations can be possible are discussed. The discussion shows that although commitment to regular and sustainable physical activity requires a profound transformation of lifestyle for the persons concerned, the collective dimension of this change is rarely taken into account..

    1993-01-01

    This guide begins with background information sections on the history of rocketry, scientific principles, and practical rocketry. The sections on scientific principles and practical rocketry are based on Isaac Newton's three laws of motion. These laws explain why rockets work and how to make them more efficient. The background sections are followed with a series of physical science activities that demonstrate the basic science of rocketry. Each activity is designed to be simple and take advantage of inexpensive materials. Construction diagrams, materials and tools lists, and instructions are included. A brief discussion elaborates on the concepts covered in the activities and is followed with teaching notes and discussion questions. The guide concludes with a glossary of terms, suggested reading list, NASA educational resources, and an evaluation questionnaire with a mailer.

    Science.gov (United States)

    Beranek, Leo L.

    2003-10-01

    Each new concert hall has the following stated goal: ``Acoustics equal to the best in the world.'' The owner can specify the number of seats, areas of public spaces, lighting intensities, etc. But, the attributes of acoustical quality cannot as yet be specified. Most acoustical consultants seem to feel that a ``seat of the pants'' experience is the only possible specification. But the architect's goal is a monument to himself and he believes the acoustical consultant should achieve the ``best in the world'' goal without visible means. Numbers for specifications are needed. In this paper 40 years of pertinent research are described: What are the critical physical attributes of good acoustics, how do we measure them, and how can they be translated into architectural specifications? Four steps have been involved: (1) interviews of conductors and music critics to determine (a) their acoustical rank orderings of a large number of halls and (b) which acoustical characteristics do they believe are important, viz., reverberance, strength of sound, etc.; (2) a determination of which physical measures correlate with their beliefs plus others that are physiologically important; (3) measurements of those physical quantities in the rank-ordered halls; and (5) the correlation of the measured values with the subjective quality ratings.

  15. The cultural production of science in reform-based physics: Girls' access, participation, and resistance

    Science.gov (United States)

    Carlone, Heidi B.

    2004-04-01

    Recent literature in science education suggests that, to transform girls' participation, learning, and identities within school science, we must think about ways to engage girls in different kinds of educational activities that promote broader meanings of science and scientist. This study was designed to examine more deeply this call for a changed science curriculum and its implications for girls' participation, interest, and emerging science identities. In this ethnographic study, I examine the culturally produced meanings of science and scientist in a reform-based physics classroom that used a curriculum called Active Physics, how these meanings reproduced and contested larger sociohistorical (and prototypical) meanings of science and scientist, and the ways girls participated within and against these meanings. The girls in this upper middle class school were mostly concerned with accessing and maintaining a good student identity (rather than connecting to science in any meaningful way) and resisted promoted meanings of science and scientist that they perceived as threatening to their good student identities. Their embrace of the ways school defined success (via grades and college admission) produced a meaning of Active Physics as a way to get credentials on a transcript and ensured their disconnection from real-world, meaningful science and science identities. The story of girls' participation and resistance in Active Physics complicates our quest for gender-fair science and highlights the power of sociohistorical meanings of schooling and science in producing educational subjects.

    2010-01-01

    In this introduction to the life and work of William Stephenson my aim is to provide a general overview of the development of his thinking and, more specifically, to highlight the importance he attached to the study of single cases. I also attempt to provide a context for an understanding of the significance of his "Tribute to Melanie Klein." Some of the principal reasons for Stephenson's marginal status in the discipline of psychology will also emerge in the course of the article. I begin by outlining some of the central notions in Q-methodology. The early sections of the article trace his roots in the north of England - the setting for his schooling and university training in physics - and then outline his encounters with Charles Spearman and Cyril Burt at University College London. The subsequent section deals with his time at the University of Oxford Institute of Experimental Psychology and the wartime interruption to his career. The next few sections take us across the Atlantic and describe some of the most significant features of his work on Q-methodology. these sections also record the difficulties Stephenson experienced before he eventually secured a tenured position at the University of Missouri School of Journalism in Columbia. In the final section I attempt to situate Q-methodology in relation to some of the principal theoretical orientations in the human sciences.

  19. Operational Health Physics-Science or Philosophy?

    Energy Technology Data Exchange (ETDEWEB)

    Carter, M. W.

    2004-07-01

    Operational health physics is concerned with protecting workers and the public from harm due to ionizing radiation. This requires the application of philosophy (ethics) as well as science. Operational health physics philosophy has been dominated by the ICRP. A particular aspect of ICRP's philosophy that is often misunderstood is (As low as reasonably achievable, economic and social factors being taken into account). (ALARA) Although the ALARA philosophy has been interpreted as a cost-benefit approach it is in fact a risk-benefit approach including social considerations as the ICRP has emphasised from time to time. A recent report has accused the ICRP of using a discarded philosophical approach, namely Utilitarianism, as a result of which its recommendations are unethical. The report suggests that a (rights) based philosophy such as Rawls' Theory of Justice would be a more appropriate basis. This paper discusses this accusation, considers some relevant philosophies and concludes that the accusation is not valid and that ICRP's recommendations are ethical but are frequently misinterpreted.

    Singh, Chandralekha; Schunn, Christian

    2016-01-01

    Recruiting and retaining highly qualified physics and physical science teachers is critical for maintaining America's global competitiveness. Unfortunately, only one third of the high school teachers in physics have a degree in physics and an even smaller number of physical science teachers in middle school have a good grasp of the scientific content they teach. Moreover, teachers often lack adequate pedagogical content knowledge to teach science effectively. Here, we discuss the development, implementation, and assessment of a course for science and engineering undergraduates designed to increase awareness and help them develop an interest and a deeper appreciation of the intellectual demands of physics teaching. The course focused on increasing student enthusiasm and confidence in teaching by providing well supported teaching opportunities and exposure to physics education research. The course assessment methods include 1) pre/post-test measures of attitude and expectations about science teaching, 2) self a...

  1. Students, language, and physics: Discourse in the science classroom

    Science.gov (United States)

    Kowalski, Susan Marie

    Women and minorities do not enter science professions at rates consistent with their populations (Rosser, 2000). A variety of theoretical frameworks and associated interventions have been cited in the literature; yet, the gender and racial gaps remain. Theoretical frameworks and the associated interventions to promote the success of women and minorities in the sciences have primarily been one dimensional: they address issues of Self (associated with experiential and psychoanalytical framings) or Language (categorical and deconstructive framings) (Grumet & Stone, 2000). Furthermore, research in science education with few exceptions (Hanson, 2004), has failed to address race and gender through an intersectional analysis. This study investigates the inclusion and exclusion of girls and minorities in the sciences by examining the connections between Self and Language in physics group work conversations. Critical Discourse Analysis was used to explore the connections between Self and Language. Eight students in two groups were the focus of the study. Transcription of conversations and coding of transcripts with students' subject positions, genres, and registers provided evidence of the reflexivity of Self and Language. Furthermore, the study demonstrated how group discourse and power imbalances within groups serve to simultaneously facilitate and constrain learning opportunities and learning itself.

    Espey, Michael Graham

    In 2009, the NCI launched the Physical Sciences - Oncology Centers (PS-OC) initiative with 12 Centers (U54) funded through 2014. The current phase of the Program includes U54 funded Centers with the added feature of soliciting new Physical Science - Oncology Projects (PS-OP) U01 grant applications through 2017; see NCI PAR-15-021. The PS-OPs, individually and along with other PS-OPs and the Physical Sciences-Oncology Centers (PS-OCs), comprise the Physical Sciences-Oncology Network (PS-ON). The foundation of the Physical Sciences-Oncology initiative is a high-risk, high-reward program that promotes a `physical sciences perspective' of cancer and fosters the convergence of physical science and cancer research by forming transdisciplinary teams of physical scientists (e.g., physicists, mathematicians, chemists, engineers, computer scientists) and cancer researchers (e.g., cancer biologists, oncologists, pathologists) who work closely together to advance our understanding of cancer. The collaborative PS-ON structure catalyzes transformative science through increased exchange of people, ideas, and approaches. PS-ON resources are leveraged to fund Trans-Network pilot projects to enable synergy and cross-testing of experimental and/or theoretical concepts. This session will include a brief PS-ON overview followed by a strategic discussion with the APS community to exchange perspectives on the progression of trans-disciplinary physical sciences in cancer research.

  6. Science Awareness and Science Literacy through the Basic Physics Course: Physics with a bit of Metaphysics?

    Science.gov (United States)

    Rusli, Aloysius

    2016-08-01

    Until the 1980s, it is well known and practiced in Indonesian Basic Physics courses, to present physics by its effective technicalities: The ideally elastic spring, the pulley and moving blocks, the thermodynamics of ideal engine models, theoretical electrostatics and electrodynamics with model capacitors and inductors, wave behavior and its various superpositions, and hopefully closed with a modern physics description. A different approach was then also experimented with, using the Hobson and Moore texts, stressing the alternative aim of fostering awareness, not just mastery, of science and the scientific method. This is hypothesized to be more in line with the changed attitude of the so-called Millenials cohort who are less attentive if not interested, and are more used to multi-tasking which suits their shorter span of attention. The upside is increased awareness of science and the scientific method. The downside is that they are getting less experience of the scientific method which intensely bases itself on critical observation, analytic thinking to set up conclusions or hypotheses, and checking consistency of the hypotheses with measured data. Another aspect is recognition that the human person encompasses both the reasoning capacity and the mental- spiritual-cultural capacity. This is considered essential, as the world grows even smaller due to increased communication capacity, causing strong interactions, nonlinear effects, and showing that value systems become more challenging and challenged due to physics / science and its cosmology, which is successfully based on the scientific method. So students should be made aware of the common basis of these two capacities: the assumptions, the reasoning capacity and the consistency assumption. This shows that the limits of science are their set of basic quantifiable assumptions, and the limits of the mental-spiritual-cultural aspects of life are their set of basic metaphysical (non-quantifiable) assumptions.

  15. Women in Physics and Other Natural Sciences in Uzbekistan

    Science.gov (United States)

    Gafurov, Ulmas; Umarova, Feruza

    2009-04-01

    Uzbekistan has about 30 scientific and higher education institutes in which research in physics and other natural sciences is carried out. Women make up about 30% of science researchers and are represented less in natural sciences and more in the humanities. In some institutes the share is less than 5-10%. Lack of financing caused the migration of many physicists into other fields and other countries. Uzbekistan has a deficiency of young scientists. To keep the accumulated scientific potential, to attract both women and men into physics and other natural sciences, it is necessary to improve the economic and technical conditions in science and to increase international collaboration.

    The world needs young people who are skillful in and enthusiastic about science and who view science as their future career field. Ensuring that we will have such young people requires initiatives that engage students in interesting and motivating science experiences. Today, students can investigate scientific phenomena using the tools, data collection techniques, models, and theories of science in physical laboratories that support interactions with the material world or in virtual laboratories that take advantage of simulations. Here, we review a selection of the literature to contrast the value of physical and virtual investigations and to offer recommendations for combining the two to strengthen science learning.

  17. BOOK REVIEW: Science Fair Projects: Physics

    Science.gov (United States)

    Reynolds, Helen

    2000-11-01

    I have often thought that the notion of a Science Fair is intrinsically a good one but have never set one up. With this book such an undertaking is possible, with 47 projects from which you can choose. Each project has a clearly stated purpose with an overview that contains the physics you need to get started. A hypothesis, or sometimes two, and a procedure detailing what the student should do follow this. The materials to be used are those you should be able to find at home, and safety guidelines as well as places the student needs adult help are clearly marked. Every project asks the student to write down the results of their experiment and decide whether or not their hypothesis was correct. There are also suggestions for taking each project further. Some of these projects are standard experiments that you may already do with students in class, for example, making plasticine boats, string telephones and levers. Most are interesting twists on standard experiments such as using a wedge as a simple machine, home-made spinning toys and the experiments with light bulbs. The latter are the only real cause for concern if students were to do these things at home as adult supervision would be essential. This is obviously an American book, though. Teachers in British classrooms would need to work out how to deal with the references to temperature in Fahrenheit and mass in ounces. Length is usually given in centimetres as well as inches. Translations of soda bottles and bobby pins would also be needed. This book is designed to be full of ideas and to give structure to projects students can do at home, not to provide ideas that you can transport into the classroom. It does this very well and I would recommend it to anyone thinking of starting up a Science Fair. Alternatively, this is an excellent resource for more interesting homework assignments that would put more responsibility on the student and give them something fun to do.

    Meyer, Eric T; Kyriakidou-Zacharoudiou, Avgousta; Power, Lucy; Williams, Peter; Venters, Will; Terras, Melissa; Wyatt, Sally

    2011-12-31

    In many ways, the physical sciences are at the forefront of using digital tools and methods to work with information and data. However, the fields and disciplines that make up the physical sciences are by no means uniform, and physical scientists find, use, and disseminate information in a variety of ways. This report examines information practices in the physical sciences across seven cases, and demonstrates the richly varied ways in which physical scientists work, collaborate, and share information and data. This report details seven case studies in the physical sciences. For each case, qualitative interviews and focus groups were used to understand the domain. Quantitative data gathered from a survey of participants highlights different information strategies employed across the cases, and identifies important software used for research. Finally, conclusions from across the cases are drawn, and recommendations are made. This report is the third in a series commissioned by the Research Information Network...

  5. The effect of levels of cooperation within physical science laboratory groups on physical science achievement

    Science.gov (United States)

    Chang, Huey-Por; Lederman, Norman G.

    The purpose of this study was to investigate the effect of the levels of group cooperation on students' achievement during a series of physical science laboratory activities. Six intact seventh-grade physical science classes taught by two teachers, with each teacher instructing three classes, were selected from two middle schools. For each teacher, one of the classes was taught with a traditional approach (no cooperative goal structure). The other two classes were assigned to a cooperative goal structure (role assignment and nonrole assignment). For the role assignment class, each student was assigned a specific role, but students in both traditional and nonrole assignment classes were not assigned roles. The Classroom Observation Instrument in Science Laboratory Activity (COISLA), which includes investigative skills (i.e., managing, manipulating, observing, reading, writing, and reporting); social skills (i.e., discussing, encouraging) and nonlearning behaviors (i.e., waiting, off-task), was used to measure the levels of group cooperation. The grades on lab reports and lab quizzes of students who were taught by the same teacher were compared to assess the effects of the different learning conditions. No significant differences on the students' final achievement were found with respect to the three instructional approaches followed by each teacher. The teacher effect was more significant than either instructional approach on managing, manipulating, observing, reading, and writing behaviors. No significant teacher effect was found for the other behaviors. Only one treatment effect was significant, writing behavior. Overall, the teacher effect was more influential than instructional approach on students' behaviors. In teacher A's classes, reading behavior predicted 21% of students' achievement. However, no significant correlations existed between the 10 collaborative behaviors and students' achievement in teacher B's classes.

    Connecting students and teachers in classrooms with science, technology, engineering, and mathematics (STEM) experts provides an invaluable opportunity. Subject matter experts can share exciting science and science-related events as well as help to "translate" science being conducted by professionals. The Expedition Earth and Beyond (EEAB) Program, facilitated by the Astromaterials Research and Exploration Science (ARES) Division at the NASA Johnson Space Center, has been providing virtual access to subject matter experts through classroom connection webinars for the last five years. Each year, the reach of these events has grown considerably, especially over the last nine months. These virtual connections not only help engage students with role models, but are also designed to help teachers address concepts and content standards they are required to teach. These events also enable scientists and subject matter experts to help "translate" current science in an engaging and understandable manner while actively involving classrooms in the journey of science and exploration.

  8. On the almost inconceivable misunderstandings concerning the subject of value-free social science.

    Science.gov (United States)

    Black, Donald

    2013-12-01

    A value judgment says what is good or bad, and value-free social science simply means social science free of value judgments. Yet many sociologists regard value-free social science as undesirable or impossible and readily make value judgments in the name of sociology. Often they display confusion about such matters as the meaning of value-free social science, value judgments internal and external to social science, value judgments as a subject of social science, the relevance of objectivity for value-free social science, and the difference between the human significance of social science and value-free social science. But why so many sociologists are so value-involved - and generally so unscientific - is sociologically understandable: The closest and most distant subjects attract the least scientific ideas. And during the past century sociologists have become increasingly close to their human subject. The debate about value-free social science is also part of an epistemological counterrevolution of humanists (including many sociologists) against the more scientific social scientists who invaded and threatened to expropriate the human subject during the past century. © London School of Economics and Political Science 2013.

    Schleyer, Claudia Janette

    The purpose of this study was two-fold. The first purpose was to identify cognitive skills and cognitive concepts perceived to be common among the high school physical education environment, and the science, math, and English classrooms. The second purpose was to identify various attitudes regarding physical education that influence the integration of the physical education curriculum with other academic subject areas, specifically, math, English, and science. Data for the study were accumulated over a six-month period using a survey instrument. Respondents included sixty-three teachers from fourteen different schools. The following findings were drawn from the analysis of data: (1) There is a significant difference (p $.05) among disciplines when teachers rank their attitudes regarding the value of physical education in the school; (4) there is no significant difference (p >.05) among disciplines when teachers rank their attitudes regarding the role of cognitive learning in physical education programs; and (5) there is no significant difference (p >$.05) among disciplines when teachers rank their attitudes regarding the integration of other academic disciplines in the school within the physical education curriculum. The following conclusions were made from the research findings: (1) English, math, and science share common cognitive skills; (2) physical education shares common cognitive concepts with math and science which provides a basis for linking these subjects together in the curriculum; (3) teachers in each of the four disciplines have a positive attitude toward the value of physical education; (4) teachers in each discipline possess a positive attitude toward the role of cognitive learning in physical education; and (5) teachers in each discipline have a positive attitude toward integration and a willingness to integrate physical education with the other subject areas.

    Science.gov (United States)

    2015-11-01

    We invite you to the Town Meeting on the role of the National Science Foundation (NSF) in supporting basic and applied research in Plasma Physics in the U.S. The overarching goal of NSF is to promote the progress of science and to enable training of the next generation of scientists and engineers at US colleges and universities. In this context, the role of the NSF Physics Division in leading the nearly 20 year old NSF/DOE Partnership in Basic Plasma Science and Engineering serves as an example of the long history of NSF support for basic plasma physics research. Yet, the NSF interest in maintaining a healthy university research base in plasma sciences extends across the Foundation. A total of five NSF Divisions are participating in the most recent Partnership solicitation, and a host of other multi-disciplinary and core programs provide opportunities for scientists to perform research on applications of plasma physics to Space & Solar Physics, Astrophysics, Accelerator Science, Material Science, Plasma Medicine, and many sub-disciplines within Engineering. This Town Meeting will provide a chance to discuss the full range of relevant NSF funding opportunities, and to begin a conversation on the present and future role of NSF in stewarding basic plasma science and engineering research at US colleges and universities. We would like to particularly encourage early career scientists and graduate students to participate in this Town Meeting, though everyone is invited to join what we hope to be a lively discussion.

  13. Cognitive-based approach in teaching 1st year Physics for Life Sciences, including Atmospheric Physics and Climate Change components

    Science.gov (United States)

    Petelina, S. V.

    2009-12-01

    Most 1st year students who take the service course in Physics - Physics for Life Sciences - in Australia encounter numerous problems caused by such factors as no previous experience with this subject; general perception that Physics is hard and only very gifted people are able to understand it; lack of knowledge of elementary mathematics; difficulties encountered by lecturers in teaching university level Physics to a class of nearly 200 students with no prior experience, diverse and sometime disadvantageous backgrounds, different majoring areas, and different learning abilities. As a result, many students either drop, or fail the subject. In addition, many of those who pass develop a huge dislike towards Physics, consider the whole experience as time wasted, and spread this opinion among their peers and friends. The above issues were addressed by introducing numerous changes to the curriculum and modifying strategies and approaches in teaching Physics for Life Sciences. Instead of a conventional approach - teaching Physics from simple to complicated, topic after topic, the students were placed in the world of Physics in the same way as a newborn child is introduced to this world - everything is seen all the time and everywhere. That created a unique environment where a bigger picture and all details were always present and interrelated. Numerous concepts of classical and modern physics were discussed, compared, and interconnected all the time with “Light” being a key component. Our primary field of research is Atmospheric Physics, in particular studying the atmospheric composition and structure using various satellite and ground-based data. With this expertise and also inspired by an increasing importance of training a scientifically educated generation who understands the challenges of the modern society and responsibilities that come with wealth, a new section on environmental physics has been developed. It included atmospheric processes and the greenhouse

  14. Learning, knowledge building, and subject matter knowledge in school science

    Science.gov (United States)

    van Aalst, Jan Cornelis Wouterus

    Following a theoretical analysis of constructivist approaches to collaborative learning, a curriculum development model, the Learning to Knowledge Building Model, is proposed. Two empirical studies of student work with Computer Supported Intentional Learning Environment (CSILE) are then presented; these lend support to the model and explicate in detail the nature and extent of the knowledge developed by elementary school students. The first study is a content analysis of a database developed by a combined Grade 5/6 class as part of a unit on heat and matter, conducted after the children completed their work; the analysis assumes the point of view of a subject matter specialist in the field of the students' inquiry. The second study was conducted while the students' investigation was in progress, and takes the point of view of curriculum coverage; it involved a teacher who used a different model of database use, as well as different subject matter. The proposed LKB model is based on a distinction Bereiter and Scardamalia (1996a) have made between learning and knowledge building (i.e., progressive collaborative problem solving); its aim is to support the design and planning of curriculum units and classroom practices in which knowledge building is central. An important feature of the model is the attention given to ensuring that students learn to evaluate their knowledge and to ask the questions that can advance shared knowledge. Among the findings of the first study are: (a) students who wrote more notes that explicated their commonsense knowledge early in the unit, by means of mixed framework notes, tended to write more notes of high scientific merit later; (b) some of the students in this category tried out their ideas in diverse problem contexts; and (c) they tended to dominate the discussions they started. The second study provides additional insight into the role of the teacher, and the potential role of subject matter specialists, in knowledge building; it

  4. High School Physics Students' Personal Epistemologies and School Science Practice

    Science.gov (United States)

    Alpaslan, Muhammet Mustafa; Yalvac, Bugrahan; Loving, Cathleen

    2017-10-01

    This case study explores students' physics-related personal epistemologies in school science practices. The school science practices of nine eleventh grade students in a physics class were audio-taped over 6 weeks. The students were also interviewed to find out their ideas on the nature of scientific knowledge after each activity. Analysis of transcripts yielded several epistemological resources that students activated in their school science practice. The findings show that there is inconsistency between students' definitions of scientific theories and their epistemological judgments. Analysis revealed that students used several epistemological resources to decide on the accuracy of their data including accuracy via following the right procedure and accuracy via what the others find. Traditional, formulation-based, physics instruction might have led students to activate naive epistemological resources that prevent them to participate in the practice of science in ways that are more meaningful. Implications for future studies are presented.

  8. The response of teachers to new subject areas in a national science curriculum: The case of the earth science component

    Science.gov (United States)

    King, Chris

    2001-11-01

    The National Curriculum for Science (NCS) introduced to schools in England and Wales in 1989 contained an earth science component that was new to many secondary science teachers. Ten years after this introduction, a survey was undertaken to test teacher perception of the effectiveness of their teaching in this subject area that was new to them, and to identify factors that might affect this effectiveness. The information gained has been used in reviewing possible curriculum changes and in developing professional development strategies that would improve the effectiveness of NCS earth science teaching. The data collected from science teachers who are currently teaching this earth science component revealed that their background knowledge of earth science from their own education was generally poor, even though most of them considered their knowledge to be moderate. The teachers indicated that the achievement of their pupils in earth science is moderate, while reports on national testing show it is poor. They reported that their main sources of earth science knowledge and understanding were science textbooks written for 11- to 16-year-old pupils (with their small earth science content of variable quality) and science colleagues (who often have poor earth science backgrounds too). Most teachers indicated that they needed more support in this area. Overall, the data indicated that while teachers consider their teaching in this area to be moderate, other evidence suggests it is poor. If this situation is not to continue it should be addressed. In the longer term the emphasis on the earth science content of the National Science Curriculum could be changed (either enhanced or reduced) within larger scale curriculum changes. Until such curriculum change takes place, effective methods of professional development should be instituted so that teachers have a much improved basis on which to build their earth science teaching. Similar measures would be necessary in other

  9. Singular perturbation in the physical sciences

    CERN Document Server

    Neu, John C

    2015-01-01

    This book is the testimony of a physical scientist whose language is singular perturbation analysis. Classical mathematical notions, such as matched asymptotic expansions, projections of large dynamical systems onto small center manifolds, and modulation theory of oscillations based either on multiple scales or on averaging/transformation theory, are included. The narratives of these topics are carried by physical examples: Let's say that the moment when we "see" how a mathematical pattern fits a physical problem is like "hitting the ball." Yes, we want to hit the ball. But a powerful stroke includes the follow-through. One intention of this book is to discern in the structure and/or solutions of the equations their geometric and physical content. Through analysis, we come to sense directly the shape and feel of phenomena. The book is structured into a main text of fundamental ideas and a subtext of problems with detailed solutions. Roughly speaking, the former is the initial contact between mathematics and p...

  13. Engineering and physical sciences in oncology: challenges and opportunities.

    Science.gov (United States)

    Mitchell, Michael J; Jain, Rakesh K; Langer, Robert

    2017-11-01

    The principles of engineering and physics have been applied to oncology for nearly 50 years. Engineers and physical scientists have made contributions to all aspects of cancer biology, from quantitative understanding of tumour growth and progression to improved detection and treatment of cancer. Many early efforts focused on experimental and computational modelling of drug distribution, cell cycle kinetics and tumour growth dynamics. In the past decade, we have witnessed exponential growth at the interface of engineering, physics and oncology that has been fuelled by advances in fields including materials science, microfabrication, nanomedicine, microfluidics, imaging, and catalysed by new programmes at the National Institutes of Health (NIH), including the National Institute of Biomedical Imaging and Bioengineering (NIBIB), Physical Sciences in Oncology, and the National Cancer Institute (NCI) Alliance for Nanotechnology. Here, we review the advances made at the interface of engineering and physical sciences and oncology in four important areas: the physical microenvironment of the tumour and technological advances in drug delivery; cellular and molecular imaging; and microfluidics and microfabrication. We discussthe research advances, opportunities and challenges for integrating engineering and physical sciences with oncology to develop new methods to study, detect and treat cancer, and we also describe the future outlook for these emerging areas.

  14. Neoliberal ideology, global capitalism, and science education: engaging the question of subjectivity

    Science.gov (United States)

    Bazzul, Jesse

    2012-12-01

    This paper attempts to add to the multifaceted discussion concerning neoliberalism and globalization out of two Cultural Studies of Science Education journal issues along with the recent Journal of Research in Science Teaching devoted to these topics. However, confronting the phenomena of globalization and neoliberalism will demand greater engagement with relevant sociopolitical thought in fields typically outside the purview of science education. Drawing from thinkers Michel Foucault, Jean Baudrillard, Judith Butler, and Louis Althusser this paper attempts to extend some key ideas coming from Ken Tobin, Larry Bencze, and Lyn Carter and advocates science educators taking up notions of ideology, discourse, and subjectivity to engage globalization and neoliberalism. Subjectivity (and its constitution in science education) is considered alongside two relevant textbook examples and also in terms of its importance in formulating political and culturally relevant questions in science education.

    This week, CERN played host to the 10th ICFA (International Committee for Future Accelerators) seminar, which brought together some 200 scientists, government agency representatives and lab directors from around the world to take the pulse of our field. ICFA seminars take place every three years, and this time the emphasis was on science as the driving force for facilities.   The theme of this year’s seminar could not have been more timely. With austerity the global norm, it is more important than ever for science to point the way to the facilities we need, and for the global community to ensure that those facilities are planned at the global level. The LHC is already a machine for the world, and although CERN’s Member States have carried the bulk of the cost, it would not have been possible without contributions from around the globe.

  3. e-Science Paradigm for Astroparticle Physics at KISTI

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available The Korea Institute of Science and Technology Information (KISTI has been studying the e-Science paradigm. With its successful application to particle physics, we consider the application of the paradigm to astroparticle physics. The Standard Model of particle physics is still not considered perfect even though the Higgs boson has recently been discovered. Astrophysical evidence shows that dark matter exists in the universe, hinting at new physics beyond the Standard Model. Therefore, there are efforts to search for dark matter candidates using direct detection, indirect detection, and collider detection. There are also efforts to build theoretical models for dark matter. Current astroparticle physics involves big investments in theories and computing along with experiments. The complexity of such an area of research is explained within the framework of the e-Science paradigm. The idea of the e-Science paradigm is to unify experiment, theory, and computing. The purpose is to study astroparticle physics anytime and anywhere. In this paper, an example of the application of the paradigm to astrophysics is presented.

American academics and administrators have multiple opportunities to internationalize their campuses and their discipline points of view. Further, Fulbright not only sends American scholars abroad but also brings scholars to the United States and should be considered a strategic internationalization opportunity both for individuals and for campuses. During the 2013-14 competition cycle there were 33 awards available in physics and astronomy and 175 all discipline awards. The presentation will guide attendees in identifying appropriate opportunities through the Fulbright Scholar Program and will make suggestions as to how to be successful in a proposal. Special attention will be given to opportunities available for specialists in physics. The workshop will also cover non-Core Fulbright Scholar opportunities for physicists and university administrators, including a number of short-term, innovative programs that send an additional 400 scholars from the United States to universities and research institutes abroad to offer expertise on issues of global interest from cutting-edge research to policy, to technical expertise in curriculum development, institutional planning, program assessment, and institutional capacity building.

    The availability of big data in materials science offers new routes for analyzing materials properties and functions and achieving scientific understanding. Finding structure in these data that is not directly visible by standard tools and exploitation of the scientific information requires new and dedicated methodology based on approaches from statistical learning, compressed sensing, and other recent methods from applied mathematics, computer science, statistics, signal processing, and information science. In this paper, we explain and demonstrate a compressed-sensing based methodology for feature selection, specifically for discovering physical descriptors, i.e., physical parameters that describe the material and its properties of interest, and associated equations that explicitly and quantitatively describe those relevant properties. As showcase application and proof of concept, we describe how to build a physical model for the quantitative prediction of the crystal structure of binary compound semiconductors.

  10. Nanoscale device physics science and engineering fundamentals

    CERN Document Server

    Tiwari, Sandip

    2017-01-01

    Nanoscale devices are distinguishable from the larger microscale devices in their specific dependence on physical phenomena and effects that are central to their operation. The size change manifests itself through changes in importance of the phenomena and effects that become dominant and the changes in scale of underlying energetics and response. Examples of these include classical effects such as single electron effects, quantum effects such as the states accessible as well as their properties; ensemble effects ranging from consequences of the laws of numbers to changes in properties arising from different magnitudes of the inter-actions, and others. These interactions, with the limits placed on size, make not just electronic, but also magnetic, optical and mechanical behavior interesting, important and useful. Connecting these properties to the behavior of devices is the focus of this textbook. Description of the book series: This collection of four textbooks in the Electroscience series span the undergrad...

  12. The Physics and Materials Science of Superheroes

    Science.gov (United States)

    Kakalios, James

    While physicists, engineers and materials scientists don't typically consult comic books when selecting research topics; innovations first introduced in superhero adventures as fiction can sometimes find their way off the comic book page and into reality. As amazing as the Fantastic Four's powers is the fact that their costumes are undamaged when the Human Torch flames on or Mr. Fantastic stretches his elastic body. In shape memory materials, an external force or torque induces a structural change that is reversed upon warming, a feature appreciated by Mr. Fantastic. Spider-Man's wall crawling ability has been ascribed to the same van der Waals attractive force that gecko lizards employ through the millions of microscopic hairs on their toes. Scientists have developed ``gecko tape, consisting of arrays of fibers that provide a strong enough attraction to support a modest weight (if this product ever becomes commercially available, I for one will never wait for the elevator again!). All this, and important topics such as: was it ``the fall or the webbing that killed Gwen Stacy, Spider-Man's girlfriend in the classic Amazing Spider-Man # 121, and the chemical composition of Captain America's shield, will be discussed. Superhero comic books often get their science right more often than one would expect!

  13. Science Understanding through Playground Physics: Organized Recess Teaching (SUPPORT)

    Kincaid, Russell

    2010-03-01

    From 1995-2007, U.S. science students in grade four scored higher than the scaled TIMSS average, but their scores did not improve over this time. Moreover, in the area of physical science, the U.S. scored significantly lower than several Asian countries, as well as Russia, England, and Latvia (TIMSS). Methods to enhance student achievement in science are still being sought. An approach to utilizing playground equipment as a teaching tool for a variety of physics concepts was developed as a physical science teaching method. This program established an appropriate set of experiments, coordinated the effort with local school districts, and implemented a brief pilot study to test the teaching methodology. The program assigned undergraduate middle school science education majors to teach small groups of fourth grade students. The experimental group used the newly developed ``Playground Physics'' methodology while the control group used traditional approaches. Follow up activities will include an expansion of the duration and the scope of the program.

    Lung, Florin; Potvin, Geoff; Sonnert, Gerhard; Sadler, Philip M.

    2012-02-01

    Using data collected from a nationally-representative sample of first-year college students, we examine how students' identity development as physics persons and their likelihood to pursue a career in physical science is predicted by differing immigrant experiences. We consider broad factors having a social, economic, or cultural nature as covariates in a propensity score model that assesses differences due to immigrant generation. Our results show that, when controlling for such factors as race/ethnicity, socio-economic status, and gender, students' physics identities and the likelihood of choosing a career in physical science are significantly higher amongst first generation students than second generation (or later) students. We conclude that physical science as a career option can be influenced by the experiences of being an immigrant and through the relationship between origin and host culture.

  1. The language of the physical sciences. Formal, technical and philosophical aspects of physics

    Manuel Béjar Gallego

    2015-01-01

    Full Text Available Nowadays modern physics is a highly formalized discipline. It is almost impossible to build a model of the whole reality because physical research requires too much specialization in local areas. Technical difficulties make harder the metaphysical analysis of the investigation. But physics is a powerful path to the very fundamental ontology. Quantum physics developed in the XX century has discovered new physical phenomena that demand a new revision of the classical ontological sets. Actually quantum physics continues improving its potential. In fact there are some heuristic theories that use quantum physics to operate in some research fields of classical human sciences. Certainly our old fashioned model of reality must be open to the last theories of modern physics. We should prepare for developing the new scientificoriented humanism. In this paper we offer seven metaphysical derivations of quantum physics.

  2. Designing Infographics to support teaching complex science subject: A comparison between static and animated Infographics

    Science.gov (United States)

    Hassan, Hesham Galal

    This thesis explores the proper principles and rules for creating excellent infographics that communicate information successfully and effectively. Not only does this thesis examine the creation of Infographics, it also tries to answer which format, Static or Animated Infographics, is the most effective when used as a teaching-aid framework for complex science subjects, and if compelling Infographics in the preferred format facilitate the learning experience. The methodology includes the creation of infographic using two formats (Static and Animated) of a fairly complex science subject (Phases Of The Moon), which were then tested for their efficacy as a whole, and the two formats were compared in terms of information comprehension and retention. My hypothesis predicts that the creation of an infographic using the animated format would be more effective in communicating a complex science subject (Phases Of The Moon), specifically when using 3D computer animation to visualize the topic. This would also help different types of learners to easily comprehend science subjects. Most of the animated infographics produced nowadays are created for marketing and business purposes and do not implement the analytical design principles required for creating excellent information design. I believe that science learners are still in need of more variety in their methods of learning information, and that infographics can be of great assistance. The results of this thesis study suggests that using properly designed infographics would be of great help in teaching complex science subjects that involve spatial and temporal data. This could facilitate learning science subjects and consequently impact the interest of young learners in STEM.

  3. The influence of physics teacher gender on college students' pursuit of careers in the physical sciences

    Science.gov (United States)

    Lung, Florin; Potvin, Geoff; Sadler, Philip M.; Sonnert, Gerhard

    2012-03-01

    In science disciplines, students develop career goals based in part on their high school experiences. Science teachers and their personal characteristics are a part of this experience. In the case of physics, teacher gender is believed to modulate the interplay between student's own gender and their gender-related perceptions of physics. Using national data from college students (PRiSE Project, N=7505), we analyze the physics teacher gender effects on the choice of a career in the physical sciences by both male and female students. We examine three sub-samples of the data: students who have not taken any high school physics courses (about 60 percent of the total), those who have taken one physics course (teacher female or male), and those who have taken two physics courses (two female, two male, or one female and one male teacher). A correspondence analysis reveals an exploratory picture of the association between primary and confounding factors. Subsequently, a linear regression on students' physical science career choices is used as a confirmatory analysis of this picture.

  4. Subjective well-being in Swedish active seniors and its relationship with physical activity and commonly available biomarkers

    Full Text Available Lovisa A Olsson,1,2 Anita Hurtig-Wennlöf,2 Torbjörn K Nilsson3 1Department of Laboratory Medicine/Clinical Chemistry, Örebro University Hospital, 2School of Health and Medical Science, Örebro University, Örebro; 3Department of Medical Biosciences/Clinical Chemistry, Umeå University, Umeå, Sweden Background: Physical activity is claimed to be related to well-being and to a lower risk of cardiovascular disease. Therefore, the possible associations of well-being with physical activity and biomarkers of somatic health were studied in a sample of Swedish active seniors to determine the strength of these associations. Methods: Three hundred and eighty-nine community-dwelling senior citizens (127 men and 262 women of mean age 74±5 years were recruited for this cross-sectional population study. Serum samples were analyzed for lipoproteins and markers of inflammation. The Psychological General Well-Being (PGWB index was used to measure subjective well-being. Physical activity was assessed by the International Physical Activity Questionnaire modified for the elderly. Results: More than 50% of men and women rated their physical activity as high; in the women, there was a significant difference between the age groups (younger and older than the median age [median =74.1 years], respectively. The mean PGWB index indicates a high degree of subjective well-being in this group of Swedish seniors. Of the PGWB subdimensions, general health had the strongest positive relationship with physical activity (r2=5.4%. for the subdimensions of depressed mood, positive well-being, vitality, and PGWB index, physical activity had an r2 ≤4%, while the contributions of sex, age, and biomarkers were minor. Conclusion: We have estimated the contribution of physical activity to the variance of subjective well-being in active seniors. Physical activity appears to play a greater role as a determinant of subjective well-being than do biomarkers of somatic health

    The present article investigates explanations for gendered trends in Physics and Engineering access, reporting findings from a large-scale study funded by the UK Economic and Social Research Council and drawing primarily on data from interviews with 132 15-16 year-old adolescents and their parents. Survey results in our study and elsewhere show strong gender disparities in anticipated pursuit of Physics after completion of compulsory education. In order to explore the constructions of gender and Physics underlying these trends, we focus on qualitative interview data, applying Foucaultian analysis of discourse to investigate gendered narratives underpinning adolescents' and their parents' articulations. This analysis reveals three key discourses at work on the topic of women's access to Physics: (a) equality of opportunity, (b) continued gender discrimination in and around Physics, and (c) Physics as quintessentially masculine. We additionally identify five distinct narratives supporting the discourse of physics as masculine. These various discourses and narratives are interrogated, and their implications explored. We conclude that it is only by disrupting prevalent constructions of the Physical sciences as a masculine and "hard" domain will we increase the presence of women in the sector. Working with young people to analyse and deconstruct the discursive assumptions made in relation to gender and Physics, as well as further work to increase accessibility and broaden representation in Physics, may be fruitful ways to challenge these longstanding associations between Physics and masculinity.

In order to test relationships, we selected the topic of rural tourism (also agritourism, agrotourism, agricultural tourism considering sociological conceptualization (social sciences, sociology and methodological approaches of information sciences (bibliometrics, scientometrics in describing fields of science or scientific disciplines. We ascertained scatter of information in citation databases (Web of Science, Scopus, Google Scholar. Functionalities were evaluated, affecting search precision and recall in information retrieval. We mapped documents to Scopus subject areas as well as Web of Science (WOS research areas and subject categories, and related publications (journals. Databases do not differ substantially in mapping this topic. Social sciences (including economics or business occupy by far the most important place. The strongest concentration was found in tourism-related journals (consistent with power laws. Agriculture-related publications are rare, accounting for some 10 % of documents. Interdisciplinarity seems to be weak. Results point to poor inclusion of emerging social topics in agricultural research whereby agriculture may lose out in possible venues of future research.

    2013-01-01

    Informal education programs organized by university physics departments are a popular means of reaching out to communities and satisfying grant requirements. The outcomes of these programs are often described in terms of broader impacts on the community. Comparatively little attention, however, has been paid to the influence of such programs on those students facilitating the informal science programs. Through Partnerships for Informal Science Education in the Community (PISEC) at the University of Colorado Boulder, undergraduate and graduate physics students coach elementary and middle school children during an inquiry-based science afterschool program. As part of their participation in PISEC, university students complete preparation in pedagogy, communication and diversity, engage with children on a weekly basis and provide regular feedback about the program. We present findings that indicate these experiences improve the ability of university students to communicate in everyday language and positively influence their perspectives on teaching and learning.

  4. SU-F-E-08: Medical Physics as a Teaching Tool for High School Science Curriculum

    Energy Technology Data Exchange (ETDEWEB)

    Buckley, L [The Ottawa Hospital Cancer Ctr., Ottawa, ON (Canada)

    2016-06-15

    Purpose: Delivering high school science curriculum in a timely manner and in way that is accessible to all students is a challenge for teachers. Although many high schools offer career workshops, these are typically directed at senior students and do not relate directly to details of the curriculum. The objective of this initiative was to create a series of lectures that use medical physics to relate many aspects of the high school science curriculum to tangible clinical applications and to introduce students to alternate pathways into a career in health sciences. Methods: A series of lectures has been developed based on the Ontario High School Science Curriculum. Each lecture uses a career in radiotherapy medical physics as the framework for discussion of topics specific to the high school course being addressed. Results: At present, these lectures have been delivered in five area high schools to students ranging from sophomores to seniors. Survey documents are given to the students before and after the lecture to assess their awareness of careers in health care, applications of physics and their general interest in the subject areas. As expected, students have limited up front awareness of the wide variety of health related career paths. The idea of combining a career lecture with topics specific to the classroom curriculum has been well-received by teachers and students alike. Conclusion: Career talks for high school students are useful for students contemplating their post- secondary career path. Relating career discussion with direct course curriculum makes their studies more relevant and engaging. Students aspiring to a career in health sciences often focus their studies on life sciences due to limited knowledge of potential careers. An early introduction to medical physics presents them with an alternate path through the physical sciences into health care.

  5. Complex network problems in physics, computer science and biology

    Science.gov (United States)

    Cojocaru, Radu Ionut

    There is a close relation between physics and mathematics and the exchange of ideas between these two sciences are well established. However until few years ago there was no such a close relation between physics and computer science. Even more, only recently biologists started to use methods and tools from statistical physics in order to study the behavior of complex system. In this thesis we concentrate on applying and analyzing several methods borrowed from computer science to biology and also we use methods from statistical physics in solving hard problems from computer science. In recent years physicists have been interested in studying the behavior of complex networks. Physics is an experimental science in which theoretical predictions are compared to experiments. In this definition, the term prediction plays a very important role: although the system is complex, it is still possible to get predictions for its behavior, but these predictions are of a probabilistic nature. Spin glasses, lattice gases or the Potts model are a few examples of complex systems in physics. Spin glasses and many frustrated antiferromagnets map exactly to computer science problems in the NP-hard class defined in Chapter 1. In Chapter 1 we discuss a common result from artificial intelligence (AI) which shows that there are some problems which are NP-complete, with the implication that these problems are difficult to solve. We introduce a few well known hard problems from computer science (Satisfiability, Coloring, Vertex Cover together with Maximum Independent Set and Number Partitioning) and then discuss their mapping to problems from physics. In Chapter 2 we provide a short review of combinatorial optimization algorithms and their applications to ground state problems in disordered systems. We discuss the cavity method initially developed for studying the Sherrington-Kirkpatrick model of spin glasses. We extend this model to the study of a specific case of spin glass on the Bethe

    In the last decade of this century and millennium, the computer and communication revolution has shown its power to transform the society. In this talk I will reflect on my personal experience of witnessing this revolution from an observation post in Silicon Valley. In particular, I will emphasize the role of physics and the interplay between science and engineering in this development. Information technology is often viewed as based on some physics discoveries and inventions such as the transistor and the semiconductor laser. Much of the subsequent development, the integrated circuit being a good example, has been an engineering feat. With shrinking dimensions of the circuits we are approaching the quantum limitations, requiring new types of computer architectures based on fundamental physics concepts. In this context we may ask if we should include the basic concepts of information and information handling as part of physics. Finally I will include some remarks on the views of physics as seen in the eyes of...

  8. Designing an Introductory Physics Course for Biological Science Students

    Heller, Kenneth

    2009-05-01

    For the past four years the School of Physics and Astronomy at the University of Minnesota has been revising its Introductory Physics Course specifically targeted to biological science and pre-medical students. The course design process includes determining the reasons that introductory physics is required by the biology faculty and determining how or if to satisfy their goals. The resulting course must substantially satisfy the goals of the biology faculty, be an introductory physics course that stresses the application of fundamental principles and relates them to complex situations typical in biology, be of interest to beginning biology students, and be teachable by ordinary physics professors. The design process for the content and the pedagogy of the course will be described as will the resulting course structure. Student performance measures for the revised course will also be given.

  9. Cognitive science and the connection between physics and mathematics

    CERN Document Server

    Mujumdar, Anshu Gupta

    2015-01-01

    The human mind is endowed with innate primordial perceptions such as space, distance, motion, change, flow of time, matter. The field of cognitive science argues that the abstract concepts of mathematics are not Platonic, but are built in the brain from these primordial perceptions, using what are known as conceptual metaphors. Known cognitive mechanisms give rise to the extremely precise and logical language of mathematics. Thus all of the vastness of mathematics, with its beautiful theorems, is human mathematics. It resides in the mind, and is not `out there'. Physics is an experimental science in which results of experiments are described in terms of concrete concepts - these concepts are also built from our primordial perceptions. The goal of theoretical physics is to describe the experimentally observed regularity of the physical world in an unambiguous, precise and logical manner. To do so, the brain resorts to the well-defined abstract concepts which the mind has metaphored from our primordial percepti...

    Age-related changes of body composition affect health status. This study aims at clarifying body composition changes in healthy elderly subjects, and evaluating the impact of physical activity on these changes. In 1999, 213 subjects ≥ 65 years recruited through advertisements underwent assessment of health state, energy expenditure by physical activity, body composition by bioimpedance analysis and body cell mass by total body potassium. In 2008, 112 of them repeated these assessments with additional determination of Barthel index, Mini Mental State Examination and Geriatric Depression Score. Lean tissues decreased in both genders (p physical activity limited lean tissue loss in men but not in women. Loss of lean tissues occurs exponentially with aging. Further research should confirm these changes in subjects over 80 years. Increasing physical activity limits fat-free mass loss in men but not women.

  13. On The Theoretical Problematic of Arabic Physical Science Or Why Did Arabic Science Fail To Achieve The Copernican Revolution?

    CERN Document Server

    Ghassib, Hisham

    2012-01-01

    A Hegelian version of the concept of problematic is used to investigate the underlying theoretical unity and structure of Arabic physical science (physics, astronomy and chemistry). A contradictory triad (associated with Platonism, Aristotelian philosophy and Ptolemaic science) is identified at the heart of the Arabic project for physical science. The paper focuses on the valiant attempts made by leading Arabic scientists to overcome these contradictions without transcending or tearing apart the prevailing problematic. The following question is then addressed: why was Arabic physical science reformist, rather than revolutionary, unlike Renaissance European physical science? An answer is proposed in terms of the history, nature and decline of Arabic rationalism.

  14. Is Subjective Social Status a Unique Correlate of Physical Health? A Meta-Analysis.

    2017-07-20

    Both social stratification (e.g., social rank) as well as economic resources (e.g., income) are thought to contribute to socioeconomic health disparities. It has been proposed that subjective socioeconomic status (an individual's perception of his or her hierarchical rank) provides increased predictive utility for physical health over and above more traditional, well-researched socioeconomic constructs such as education, occupation, and income. PsycINFO and PubMed databases were systematically searched for studies examining the association of subjective socioeconomic status (SES) and physical health adjusting for at least 1 measure of objective SES. The final sample included 31 studies and 99 unique effects. Meta-analyses were performed to: (a) estimate the overlap among subjective and objective indicators of SES and (b) estimate the cumulative association of subjective SES with physical health adjusting for objective SES. Potential moderators such as race and type of health indicator assessed (global self-reports vs. more specific and biologically based indicators) were also examined. Across samples, subjective SES shows moderate overlap with objective indicators of SES, but associations are much stronger in Whites than Blacks. Subjective SES evidenced a unique cumulative association with physical health in adults, above and beyond traditional objective indicators of SES (Z = .07, SE = .01, p Subjective SES may provide unique information relevant to understanding disparities in health, especially self-rated health.

    The ability of scientists to articulate the importance and value of their research has become increasingly important in the present climate of declining budgets, and this is most critical in the field of nuclear science ,where researchers must fight an uphill battle against negative public perception. Yet nuclear science encompasses important technical and societal issues that should be of primary interest to informed citizens, and the need for scientists trained in nuclear techniques are important for many applications in nuclear medicine, national security and future energy sources. The NSAC Education Subcommittee Report [1] identified the need for a nationally coordinated effort in nuclear science outreach, naming as its first recommendation that `the highest priority for new investment in education be the creation by the DOE and NSF of a Center for Nuclear Science Outreach'. This talk will review the present status of public outreach in nuclear science and highlight some specific efforts that have taken place during the World Year of Physics.

  16. Stealth Physics: Sneaking in Science Where People Least Expect It

    Science.gov (United States)

    Leslie-Pelecky, Diandra

    2014-03-01

    The majority of science outreach focuses on a small group of well-educated older people (still majority male) with an already existing interest in science. The dominant paradigm of ``you-come-to-us'' leaves out many more people than it brings in. Most people only become interested in science when it affects something they care about, whether that be their personal or economic health, or their recreational passions. My experiences writing and promoting The Physics of NASCAR forced me to change my approach to science outreach in terms not only of how to do outreach, but also what impact I hope to have. There are 75 million NASCAR fans. Every fan wants to know one thing: Why isn't my driver winning? I'll share my experiences using television, radio and blogging to reach an oft-neglected group that is characterized by a certainty that they - even if they wanted to - are not capable of understanding science. This lack of self-efficacy is likely the biggest barrier scientists have to reaching the general public. My central thesis is that ``Science for All'' doesn't necessarily mean that scientists need to convince the public that what the scientists are doing is interesting. It means that scientists doing outreach need to learn how to engage the public with science that affects things the public already cares about.

  17. Sociology, Basis for the Secondary-School Subject of Social Sciences

    Directory of Open Access Journals (Sweden)

    Lieke Meijs

    2009-12-01

    Full Text Available This paper reformulates the question of ‘sociology, who needs it’ in two ways, The first question we address is that of the reason why the educational system itself did not come to sociology for help in their long quest for a clear-cut content of the subject. The second question is why sociology did not adopt the orphaned subject of social studies back in 1960. The answer to the first question lies in the vulnerability of a subject that is dependent for its continued existence on the political leanings of the day. This led to a new goal for the subject almost every decade: from social education in the sixties and social and political education in the seventies, to a focus on citizenship education in the nineties. Although the objective was renamed on several occasions, the prescriptive viewpoint is recognizable in each. This perspective is difficult to reconcile with a social science content. The answer to the second questions points towards Dutch social scientists with a strong focus on academic sociology and not for critical, policy or public sociology. This choice was also made in order to win the competition with psychologists and for the discipline to get rid of the poor image it had acquired in the 1960s. The new subject social sciences, with a strong focus on science made it possible for sociology to become the pillar of this new subject.

    Full Text Available BACKGROUND: The inclusion of students with special educational needs is a process, which faces many challenges. An essential condition for the success of inclusion is the competence of physical educators. We suggest that it is necessary to establish courses focused on adapted physical activity as part of the university education for physical education (PE teachers. OBJECTIVES: The aim of this study is to analyze courses focused on adapted physical activity within teacher preparation programs. METHODS: We conducted quantitative and qualitative content analysis of subjects which was focused on adapted physical activity at selected public universities in the Czech Republic. In total, subjects from the six faculties met the conditions. RESULTS: The results show the lack of emphasis for this area in the current PE teacher preparations programs, which is one of basic requirements for success of the inclusion process.

    Full Text Available This study aims to investigate the student perception on teacher interpersonal behavior and their attitude toward science subject. 207 respondents were involved, consisted of 200 students in 10-12 grade and 7 science teachers of public high school in Aceh. Two types of questionnaires were used namely the Indonesian version of the questionnaire of teacher interaction (QTI and test of science related attitude (TOSRA. SPSS program were applied to process the data statistically. First, the reliability of questionnaires is measured using descriptive statistics of all and each scale of QTI. Second, the difference between students’ perceptions on the actual and ideal teacher interpersonal behavior was computed by Paired Sample t-tests. Third, the relationship between students' perception on teachers’ interpersonal behavior and students' attitudes towards science subjects was compared using multiple regression analysis-standardized regression coefficient β. The finding showed that the Indonesian version of questionnaire of teacher interaction (QTI is reliable (αC = 0.86, to be applied to the high school students in the regency. It is generally seen that the students consider their teachers demonstrate more positive interpersonal behavior than the negative. However, it is clearly seen that between actual and ideal perceptions on the whole scale of QTI is significantly different. Last, from the three scales of teacher interpersonal behavior, helping/friendly, dissatisfaction, and admonishing appeared influential, only the helping/friendly scale significantly correlate (at the .05 level with student attitudes toward science subject.

    Leisure activities, particularly exercise, play a protective role against dementia in healthy people, but it is unknown if this protective effect could be generalized to subjects with mild cognitive impairment (MCI). To investigate the influence of leisure activities on the risk of progression of MCI to dementia. 176 MCI subjects attending a memory clinic underwent a standardized lifestyle questionnaire between October 2007 and May 2010. Social, cognitive, and physical scores were derived based on the assiduity of interpersonal contacts and on the frequency of participation in individual leisure activities. Subjects were requested to return every 12 months for dementia surveillance. The outcome measure was the risk of dementia associated with social, cognitive, and physical scores. Over a median follow-up time of 2.59 year, 92 (52.2%) MCI subjects developed dementia. Subjects with physical scores in the highest third had a lower risk (HR 0.44; 95% CI 0.23-0.85) of dementia compared with those in the lowest third. No association was found between cognitive or social scores and the risk of dementia. To our knowledge, this is the first prospective clinical study which demonstrates that high levels of participation in physical leisure activities are associated with reduced risk of dementia in subjects with MCI. In line with findings coming from community-based studies on healthy elderly, our finding suggests that the protective role of exercise against the development of dementia can be generalized to MCI subjects seen in clinical practice. Clinicians should encourage MCI subjects to participate in physical leisure activities.

    Science.gov (United States)

    Finn, Kevin Eugene

    Background: National recommendations to increase school-based physical activity and promote academic success advise incorporating movement into traditional classroom lessons. Classroom-based physical activities have favorable associations with indicators of cognitive functioning, academic behaviors, and academic achievement. Purpose: This study analyzed the Active Science framework, which incorporated school-based physical activity within interactive science classroom lessons. Specifically, the study measured the effects of the Active Science framework on student physical activity levels in the classroom, student learning of science inquiry skills and content knowledge, and student perceptions of physical activity and science. A secondary purpose was to evaluate the teachers' perceptions on the implementation of the framework. Subjects: Participants were 37 Hispanic girls (age=11.1 +/-0.8 yr) in mixed 5th/6th grade science classes in a private, urban middle school. Methods: Physical activity levels of the students during the Active Science framework were measured using pedometers and heart rate monitors. Pre- and post-tests were used to assess the levels of learning achieved by the students in science inquiry skills and content during the Active Science framework. Student perceptions and attitudes toward science and physical activity were measured during student focus groups and pre-post perception surveys. Lesson plan evaluations completed by the teachers and structured interviews provided data on implementation of the framework. Results: Physical activity results showed heart rate (146 +/-9 bpm); maximal heart rate (196 +/-10.6 bpm); time (35 +/-2.5 mins); steps (3050 +/-402.7); calories (99 +/-8.4 kcal); and distance (1.1 +/-0.2 miles) while performing the activity portion of the science lessons were consistent with national recommendations for accumulating school-based physical activity. Significant increases in science content and skills test scores with a 22

    The study aims to examine whether the reciprocal effects of physical morbidity and depression are moderated by subjective age-that is, individuals' perception of themselves as young or old. Data from the first two waves of the Midlife in the United States study (1995-6, T1; 2004-6, T2; http://midus.wisc.edu/) were analyzed using a cross-lagged design. We assessed 3,591 individuals who participated in both waves and provided full data on all the relevant variables (mean age at T1 = 47.4). Depression and the number of chronic illnesses (the indicator of physical morbidity) were measured at both waves and were tested as predictors and outcomes in a cross-lagged model. The moderating role of subjective age was assessed by examining whether T1 variables interacted with subjective age in predicting T2 outcomes. Subjective age moderated the T1 depression-T2 morbidity relationship, so that the relationship was stronger for those with older subjective age. Subjective age did not moderate the T1 morbidity-T2 depression relationship. Older subjective age could be a risk factor for experiencing greater physical morbidity following depression.

  11. Developing the learning physical science curriculum: Adapting a small enrollment, laboratory and discussion based physical science course for large enrollments

    Directory of Open Access Journals (Sweden)

    Fred Goldberg

    2012-05-01

    Full Text Available We report on the adaptation of the small enrollment, lab and discussion based physical science course, Physical Science and Everyday Thinking (PSET, for a large-enrollment, lecture-style setting. Like PSET, the new Learning Physical Science (LEPS curriculum was designed around specific principles based on research on learning to meet the needs of nonscience students, especially prospective and practicing elementary and middle school teachers. We describe the structure of the two curricula and the adaptation process, including a detailed comparison of similar activities from the two curricula and a case study of a LEPS classroom implementation. In LEPS, short instructor-guided lessons replace lengthier small group activities, and movies, rather than hands-on investigations, provide the evidence used to support and test ideas. LEPS promotes student peer interaction as an important part of sense making via “clicker” questions, rather than small group and whole class discussions typical of PSET. Examples of student dialog indicate that this format is capable of generating substantive student discussion and successfully enacting the design principles. Field-test data show similar student content learning gains with the two curricula. Nevertheless, because of classroom constraints, some important practices of science that were an integral part of PSET were not included in LEPS.

    Full Text Available The possible effects of different organisations of the science curriculum in schools participating in PISA 2003 are tested with a hierarchical linear model (HLM of two levels. The analysis is based on science results. Swedish schools are free to choose how they organise the science curriculum. They may choose to work subject-specifically (with Biology, Chemistry and Physics, integrated (with Science or to mix these two. In this study, all three ways of organising science classes in compulsory school are present to some degree. None of the different ways of organising science education displayed statistically significant better student results in scientific literacy as measured in PISA 2003. The HLM model used variables of gender, country of birth, home language, preschool attendance, an economic, social and cultural index as well as the teaching organisation.

A database of 82 papers that described female subject groups containing information on preexperimental maximal cycle-protocol designs, terminology, biometrical and physiological parameters, and cycling experience was analyzed. Subject groups were divided into performance levels (PLs), according to the nomenclature. Body mass, body-mass index, maximal oxygen consumption (VO2max), peak power output (PPO), and training status were compared between PLs and between female and male PLs. Five female PLs were defined, representing untrained, active, trained, well-trained, and professional female subjects. VO2max and PPO significantly increased with PL, except for PL3 and PL4 (P groups. Relative VO2max is the most cited parameter for female subject groups and is proposed as the principal parameter to classify the groups. This systematic review shows the large variety in the description of female subject groups in the existing literature. The authors propose a standardized preexperimental testing protocol and guidelines to classify female subject groups into 5 PLs based on relative VO2max, relative PPO, training status, absolute VO2max, and absolute PPO.

    Full Text Available Background: In the present study, subjective vitality considered to be one of the contributions provided by participation in physical activity is examined on a sample of pre-service teachers. When teachers who are important part of education system are healthy and fit, it will help to build future generations. Materials: The research was conducted in the city of Trabzon, located in the northeastern region of Turkey. The sample of the study is composed of 328 last grade pre-service teachers (133 women, 195 men, age: 23.14 ± 2.62 studying at Karadeniz Technical University in the academic year of 2015-2016. Data was collected through Childhood and Adolescence Physical Activity Levels Questionnaire, Subjective Vitality Scale, and a personal information form asking for information about gender, doing sports as a certified sportsman/woman and department. Results: The research results yielded a significant difference between subjective vitality levels of those who do sports as a certified sportsman/woman and those who do not, and between pre-service teachers of physical education and those of other departments (p<0,01. There was also a positive and low-level significant relationship between subjective vitality and physical activity experiences of pre-service teachers (r= .23; p<0.01. However, subjective vitality did not differ significantly by gender. Conclusions: The research results seem to support other studies that reveal social and psychological contributions provided by participation in physical activity. Therefore, participation in physical activity seems to have positive effects on the subjective vitality of pre-service teachers.

  18. Role of the epistemic subject in Piaget's genetic epistemology and its importance for science education

    Science.gov (United States)

    Niaz, Mansoor

    According to Piaget, a fundamental epistemological distinction must be made between the psychological and the epistemic subject. The epistemic subject is studied by the genetic epistemologist who charts development through a common universal rationality, which develops, whereas the psychological subject is studied by the developmental/cognitive psychologist by focusing on accidental contingencies surrounding particular people and their individual differences. The epistemic subject as compared to the psychological subject is an idealized abstraction, viz., that set of underlying epistemic structures common to everyone at the same level of development. The objective of this study is to investigate the degree to which investigators in science education conceptualize the difference between the epistemic and the psychological subjects. It is argued that just as the ideal gas law (based on the theoretical formulation of Maxwell and Boltzmann) provides a general model to which the real gases approximate under different experimental conditions, so we can consider (by abduction) the epistemic subject to be an ideal knower to which the real (psychological) subjects approximate to varying degrees. The difference between the epistemic and the psychological subjects, however, cannot be used as an epistemological shield in defense of Piagetian theory. Any test of the Piagetian theory must involve psychological or real subjects. Empirical testability, however, need not be equated to being scientific. An analogy is drawn between Galileo's idealization, which led to the discovery of the law of free-fall, and Piaget's epistemic subject. Research conducted in science education shows that at least for some critics the wide variations in the age at which individuals acquire the different Piagetian stages is crucial for rejecting the theory. It is argued that the real issue is not the proportion of heterogeneity but the understanding that Piaget, by neglecting individual differences

    2013-07-01

    Full Text Available A Hegelianized version of Althusser’s concept of problematic is used to investigate the underlying theoretical unity and structure of Arabic physical science (physics, astronomy and chemistry. A contradictory triad (associated with Platonism, Aristotelianism and Ptolemaism is identified at the heart of the Arabic project for physical science. This article focuses on the valiant attempts made by leading Arabic scientists to overcome these contradictions without transcending or tearing apart the prevailing problematic. The following question is then addressed: why was Arabic physical science reformist, rather than revolutionary, unlike Renaissance European physical science? An answer is proposed in terms of the history, nature and decline of Arabic rationalism.

    This study investigated differences in social-cognitive predictors and self-regulatory planning, as proposed by the health action process approach (HAPA), across three different subjective physical age groups for physical activity. With a cross-sectional design, 521 participants across the chronological age span from 25 to 86 years (M = 48.79; SD = 12.66) were separated into three groups: those who feel physically younger than they are in terms of chronological age, the same perceived and chronological age, and feeling physically older compared to their chronological age. Participants were assessed regarding their perceived vulnerability, outcome expectancies, general intentions, planning, self-efficacy, and stages of physical activity (non-intenders, intenders, and actors). Data were analysed via mean comparison and multigroup structural equation modelling. Mean differences for all but one construct were eminent in all groups, generally showing that those feeling physically younger also report better social-cognitive predictors of physical activity (e.g. lower perceived vulnerability) in comparison to those who feel the same age or older. The model showed that basic working mechanisms of the HAPA can be applied to all groups. With that, the results provide for the first time evidence that principle working mechanism of the HAPA can be applied to all subjective physical age groups. These may be used to tailor health promoting interventions according to participants' needs as a more suitable proxy than chronological age.

    From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics the disciplines NASA refers to as heliophysics have yielded spectacular insights into the phenomena that affect our home in space. This report, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized over the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily to NASA (Science Mission Directorate -- Heliophysics Division) and the National Science Foundation (NSF) (Directorate for Geosciences -- Atmospheric and Geospace Sciences) for action, the report also recommends actions by other federal agencies, especially the National Oceanic and Atmospheric Administration (NOAA) those parts of NOAA charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in the main text of the report.

  3. From object to subject: hybrid identities of indigenous women in science

    Science.gov (United States)

    McKinley, Elizabeth

    2008-12-01

    The use of hybridity today suggests a less coherent, unified and directed process than that found in the Enlightenment science's cultural imperialism, but regardless of this neither concept exists outside power and inequality. Hence, hybridity raises the question of the terms of the mixture and the conditions of mixing. Cultural hybridity produced by colonisation, under the watchful eye of science at the time, and the subsequent life in a modern world since does not obscure the power that was embedded in the moment of colonisation. Indigenous identities are constructed within and by cultural power. While we all live in a global society whose consequences no one can escape, we remain unequal participants and globalisation remains an uneven process. This article argues that power has become a constitutive element in our own hybrid identities in indigenous people's attempts to participate in science and science education. Using the indigenous peoples of Aotearoa New Zealand (called Māori) as a site of identity construction, I argue that the move from being the object of science to the subject of science, through science education in schools, brings with it traces of an earlier meaning of `hybridity' that constantly erupts into the lives of Māori women scientists.

  4. Optimizing Introductory Physics for the Life Sciences: Placing Physics in Biological Context

    2014-03-01

    Physics is a critical foundation for today's life sciences and medicine. However, the physics content and ways of thinking identified by life scientists as most important for their fields are often not taught, or underemphasized, in traditional introductory physics courses. Furthermore, such courses rarely give students practice using physics to understand living systems in a substantial way. Consequently, students are unlikely to recognize the value of physics to their chosen fields, or to develop facility in applying physics to biological systems. At Swarthmore, as at several other institutions engaged in reforming this course, we have reorganized the introductory course for life science students around touchstone biological examples, in which fundamental physics contributes significantly to understanding biological phenomena or research techniques, in order to make explicit the value of physics to the life sciences. We have also focused on the physics topics and approaches most relevant to biology while seeking to develop rigorous qualitative reasoning and quantitative problem solving skills, using established pedagogical best practices. Each unit is motivated by and culminates with students analyzing one or more touchstone examples. For example, in the second semester we emphasize electric potential and potential difference more than electric field, and start from students' typically superficial understanding of the cell membrane potential and of electrical interactions in biochemistry to help them develop a more sophisticated understanding of electric forces, field, and potential, including in the salt water environment of life. Other second semester touchstones include optics of vision and microscopes, circuit models for neural signaling, and magnetotactic bacteria. When possible, we have adapted existing research-based curricular materials to support these examples. This talk will describe the design and development process for this course, give examples of

    Recreational soccer (RS) is becoming a popular alternative to the classical continuous exercise mode used for the improvement of cardiovascular and metabolic fitness in untrained people. The objective of this paper was to conduct a detailed systematic review of the literature, identifying the physiological responses to RS and the training effects of RS on aerobic fitness and health in untrained healthy individuals and clinical patients. PubMed, Google Scholar and ScienceDirect databases were searched using terms related to recreational soccer. Inclusion criteria were randomized controlled trials (RCT) that assessed acute physiological responses to RS or the training effects of RS on physical fitness and health in sedentary, untrained subjects of any age or health status. All studies were assessed for methodological quality using the PEDro scale. Thirty-five articles met the inclusion criteria; seven examined the acute response to RS, and 28 assessed training effects. Clear evidence was found that RS had positive effects on many health-related indices and variables, including VO2max (gains of 7-16%), blood pressure (reductions of 6-13 mmHg), body composition (decreased fat mass and improved indices of bone health), and metabolic and cardiac function. These positive effects were observed in both healthy individuals and clinical patients, irrespective of age or sex. Although this review provides clear evidence of the positive effects of RS on health, most studies had limitations of methodology (an average PEDro score < 6). Furthermore, many of the training studies were from a small number of research groups. Future studies should be extended to other countries and institutions to ensure generality of the results. Regular RS training leads to significant cardiovascular and muscular adaptations and gains of health both in sedentary individuals and clinical patients at all ages, suggesting that RS is a potentially highly motivational method to enhance population health.

    Traditional approaches of medicinal chemistry focus on finding novel structures possessing desired biological properties, or on relating chemical details to a particular biological function. Here the aim is to hit the therapeutic target of interest rather than to understand and exploit its origin. Consequently, molecular mechanisms underlying the disease are of much lesser concern, with intuitive designs continuing to be most successful. Physical sciences can offer alternative ways of tackling the problem by establishing structural continuums between different time and length scales spanning physical phenomena of life processes and their disorders. This can be achieved by the use of approximated physical models providing a rationale for interconversions between different but related scales, which can further be extended with chemical details obtained from complementary experimental data.

    The expansion of scientific materials in the last few decades, demands that the contemporary educational system should select and develop methods of effective learning in the process of acquiring skills and knowledge usable and feasible for a longer period of time. Grammar schools as general educational institutions possess all that is necessary for the development of new teaching methods and fitting into contemporary social tendencies. In the languages and social sciences department in of grammar schools physics is the only natural sciences subject present during all four years. The classical approach to teaching is tiring as such and creates aversion towards learning physic when it deals with pupils oriented towards social sciences. The introduction of scientific methods raises the motivation to a substantial level and when applied both the teacher and pupils forget when the class starts or ends. The assignment has shown the analysis of initial knowledge of physics of the pupils attending the first grade of languages and social sciences department of of grammar schools as a preparation for the introduction of the scientific method, the analysis of the initial test with the topic of gravitation, as well as the analysis of the final test after applying the scientific method through the topic of gravitation. The introduction of the scientific method has duly justified the expectations and resulted in increasing the level of achievement among the pupils in the experimental class.

    2014-11-05

    Quantitative methods and approaches have been playing an increasingly important role in cell biology in recent years. They involve making accurate measurements to test a predefined hypothesis in order to compare experimental data with predictions generated by theoretical models, an approach that has benefited physicists for decades. Building quantitative models in experimental biology not only has led to discoveries of counterintuitive phenomena but has also opened up novel research directions. To make the biological sciences more quantitative, we believe a two-pronged approach needs to be taken. First, graduate training needs to be revamped to ensure biology students are adequately trained in physical and mathematical sciences and vice versa. Second, students of both the biological and the physical sciences need to be provided adequate opportunities for hands-on engagement with the methods and approaches necessary to be able to work at the intersection of the biological and physical sciences. We present the annual Physiology Course organized at the Marine Biological Laboratory (Woods Hole, MA) as a case study for a hands-on training program that gives young scientists the opportunity not only to acquire the tools of quantitative biology but also to develop the necessary thought processes that will enable them to bridge the gap between these disciplines. © 2014 Shekhar, Zhu, Mazutis, Sgro, Fai, and Podolski.

    Full Text Available The problem of internet resources application for forming of pupils ecological knowledge at the study of natural sciences subjects is considered. It is noticed, that distribution of ecological knowledge and development of ecological education became the near-term tasks of school education, taking into account a global ecological crisis. It is therefore important to use in school preparation all possibilities that allow to promote the level of ecological knowledge of students and to influence the same on forming of modern views in relation to environmental preservation. Considerable attention is given to advices for the teachers of natural sciences subjects in relation to methodology of the internet resources use at preparation and realization of practical and laboratory works and other forms of educational-searching activity of students.

  2. Subjective relative deprivation is associated with poorer physical and mental health.

    2015-12-01

    Substantial epidemiological evidence has shown that income inequality and objective measures of relative deprivation are associated with poorer health outcomes. However, surprisingly little research has examined whether subjective feelings of relative deprivation are similarly linked with poorer health outcomes. The relative deprivation hypothesis suggests that inequality affects health at the individual level through negative consequences of social comparison. We directly examined the relationship between subjective feelings of personal relative deprivation and self-reported physical and mental health in a diverse community sample (n = 328). Results demonstrated that subjective feelings of personal relative deprivation are associated with significantly poorer physical and mental health. These relationships held even when accounting for covariates that have been previously associated with both relative deprivation and health. These results further support the link between relative deprivation and health outcomes and suggest that addressing root causes of relative deprivation may lead to greater individual health.

  3. Secondary Physical Science Teachers' Conceptions of Science Teaching in a Context of Change

    Taylor, Dale L.; Booth, Shirley

    2015-05-01

    Pre-service teachers enter initial teacher education programmes with conceptions of teaching gleaned from their own schooling. These conceptions, which include teachers' beliefs, may be resistant to change, which is a challenge in contexts where teacher educators hope that teachers will teach in ways different from their own schooling. Conceptions of teaching found in different cultural and disciplinary contexts have contextual differences but have resonances with the results of research into teacher beliefs. Our sample of eight South African secondary physical science teachers was schooled in a system which encouraged knowledge transmission, but they were prepared in their initial teacher education for a learner-centred approach. After they had taught for a few years, we explored their conceptions of science teaching, using phenomenographic interviews. Four conceptions emerged inductively from the analysis: transferring science knowledge from mind to mind; transferring problematic science knowledge from mind to mind; creating space for learning science knowledge and creating space for learning problematic science knowledge. Internally these conceptions are constituted by three dimensions of variation: the nature of the science knowledge to be learnt, the role of the students and the role of the teacher. Media and practical work play different roles in the external horizon of these conceptions. These conceptions reflect the disciplinary context as well as the emphases of the sample's initial teacher education programme. This suggests that initial teacher education can significantly shape teachers' conceptions of teaching.

    Physical exercise recommendations become particularly effective when embedded into medical rehabilitation. However, little is known about long-term behaviour maintenance and its effect on sickness absence and subjective employability. The current longitudinal observational study investigated self-reported physical exercise, sickness absence and subjective employability over a period of 8 years. A total of 601 (T0) outpatients (mean age 45.14 years; standard deviation 10.73 years, age range 18-65 years) with different orthopaedic disorders were recruited during their 3-week medical rehabilitation in Germany. Of these, 61.7% (n = 371) were female. Follow-ups were carried out at 6 months (T1, n = 495), 12 months (T2, n = 340), 3 years (T3, n = 296) and 8 years (T4, n = 142) after baseline. Patient characteristics, exercise status, social-cognitive variables, sickness absence and subjective employability were obtained via self-report questionnaires. SPSS hierarchical regression models were used for data analysis, controlling for baseline measures and sociodemographic variables. Physical exercise status 6 months after rehabilitation treatment (T1) predicted sickness absence at 12 months (T2). Inactive people were 3.28 times more likely to be on sick leave at T2. In addition, physical exercise at T1 predicted subjective employability 12 months (T2) and 3 years (T3) later. Those who met the recommendations to be physically active for at least 40 min a week were more likely to feel able to work. Exercise appears to play an important role in reducing sickness absence and subjective employability and should be promoted within and after rehabilitation treatment.

    2014-07-30

    High energy and nuclear physics research at MIT is conducted within the Laboratory for Nuclear Science (LNS). Almost half of the faculty in the MIT Physics Department carry out research in LNS at the theoretical and experimental frontiers of subatomic physics. Since 2004, the U.S. Department of Energy has funded the high energy physics research program through grant DE-FG02-05ER41360 (other grants and cooperative agreements provided decades of support prior to 2004). The Director of LNS serves as PI. The grant supports the research of four groups within LNS as “tasks” within the umbrella grant. Brief descriptions of each group are given here. A more detailed report from each task follows in later sections. Although grant DE-FG02-05ER41360 has ended, DOE continues to fund LNS high energy physics research through five separate grants (a research grant for each of the four groups, as well as a grant for AMS Operations). We are pleased to continue this longstanding partnership.

    Full Text Available The policy of changing the medium of instruction in the teaching of mathematics and science from Bahasa Melayu to English is an important innovation affecting teachers of mathematics and science. It poses special challenges not only for teachers who have been trained in the Malay medium but also for those trained in English. This investigation seeks to find out the achievement of students in mathematic and science subjects after considering the impact of prominent independent variables such as, the school, class and home environment, the teaching methodology and the teachers’ attitude. Analysis of the development in the state of Terengganu has been carried out by the distribution of questionnaires to teachers involved. Result of the correlation and multiple regressions indicated that all the three factors are significantly associated towards students’ achievement. However, the teaching methodology indicated a low level of moderate correlation which is believed to be the immediate issue that needed to be addressed in the new system.

    Lee, Okhee

    This study examined the interrelationships among three major components of classroom teaching: subject matter content knowledge, classroom management, and instructional practices. The study involved two middle school science classes of different achievement levels taught by the same female teacher. The teacher held an undergraduate degree with a major in social studies and a minor in mathematics and science from an elementary teacher education program. The findings indicated that the teacher's limited knowledge of science content and her strict classroom order resulted in heavy dependence on the textbook and students' individual activities (e.g., seatwork) and avoidance of whole-class activities (e.g., discussion) similarly in both classes. Implications for educational practices and further research are discussed.

    University of Delaware faculty in the geological sciences, biological sciences, and the physics and astronomy departments have partnered with faculty and researchers from the school of education to form a continuum for K- 8 pre-service teacher preparation in science. The goal of the continuum is to develop integrated understandings of content and pedagogy so that these future teachers can effectively use inquiry-based approaches in teaching science in their classrooms. Throughout the continuum where earth science content appears an earth system science approach, with emphasis on inquiry-based activities, is employed. The continuum for K-8 pre-service teachers includes a gateway content course in the earth, life, or physical sciences taken during the freshman year followed by integrated science content and methods courses taken during the sophomore year. These integrated courses, called the Science Semester, were designed and implemented with funding from the National Science Foundation. During the Science Semester, traditional content and pedagogy subject matter boundaries are crossed to stress shared themes that teachers must understand to teach standards-based science. Students work collaboratively on multidisciplinary problem-based learning (PBL) activities that place science concepts in authentic contexts and build learning skills. They also critically explore the theory and practice of elementary science teaching, drawing on their shared experiences of inquiry learning during the Science Semester. The PBL activities that are the hallmark of the Science Semester provide the backdrop through which fundamental earth system interactions can be studied. For example in a PBL investigation that focuses on kids, cancer, and the environment, the hydrologic cycle with emphasis on surface runoff and ground water contamination is studied. Those students seeking secondary certification in science will enroll, as a bridge toward their student teaching experience, in an

    Full Text Available The issue of this research emphasizes on the implementation of character building values through physical education learning in elementary school. The effort in developing this character building practice is essential to be done in order to tackle moral and character crises, which already occur in both individual and collective levels reflected in educational institution from elementary school to higher education. Hence, to form culture and national character, educational program and process are inseparable from environmental factor including the values of society, culture, and humanity. Physical education subject that is based on 2013 Curriculum has significant difference compared to the previous physical education subject. This is due to the fact that integrated physical education has its own uniqueness in terms of planning, systematic implementation, and instructional medium. This research aims at producing guidance in implementing character values integrated in physical education in elementary school. The method used in this research is research and development (R&D method, which includes preliminary research, model designing, limited trial, and extensive trial, as well as validation and dissemination. The findings of the research show that character values can be implemented in physical education in elementary schools in Sumedang Regency.

    Cardiovascular disease (CVD) is the leading cause of death for African American (AA) women in the United States. Despite high prevalence of CVD risk factors, AA women perceive their CVD risk as low. Our objectives were to (1) identify relationships between subjective (self-reported perceived) CVD risk and objective CVD risk estimated by the American College of Cardiology/American Heart Association atherosclerotic CVD (ASCVD) risk estimator, (2) identify demographic and psychosocial factors associated with subjective perceived risk and discrepancy with objective estimated CVD risk, and (3) determine whether subjective perceived CVD risk was associated with physical activity (PA) adherence. This was a secondary data analysis of data collected from a 12-month lifestyle PA intervention conducted with 281 AA women. Subjective perceived CVD risk was measured by 1 question; objective estimated CVD risk was calculated using the ASCVD score. Women were categorized by congruence or discrepancy between subjective perceived and objective estimated CVD risk. Subjective perceived CVD risk and objective ASCVD risk scores were both low. Approximately 20% subjectively perceived their risk as lower than objective ASCVD scores. Atherosclerotic CVD risk discrepancy groups differed by depressed mood symptoms. Participants reported many perceived barriers to PA. Perceived CVD risk was not related to PA adherence. The significance of associated CVD risk factors may be underestimated by AA women, leading to discrepancy between subjective and objective risk estimates. Research is needed to clarify relationships among perceived risk, estimated risk using risk calculators such as ASCVD, and health behavior.

    The restructuring of the research capabilities of the International Space Station has forced a reassessment of the Physical Sciences research plans and a re-targeting of the major scientific thrusts. The combination of already selected peer-reviewed flight investigations with the initiation of new research and technology programs will allow the maximization of the ISS scientific and technological potential. Fundamental and applied research will use a combination of ISS-based facilities, ground-based activities, and other experimental platforms to address issues impacting fundamental knowledge, industrial and medical applications on Earth, and the technology required for human space exploration. The current flight investigation research plan shows a large number of principal investigators selected to use the remaining planned research facilities. c2003 American Institute of Aeronautics and Astronautics.

  14. Invisible World and Modern Physics: Modern Science and Theology

    Science.gov (United States)

    Theodossiou, E.; Manimanis, V. N.; Danezis, E.

    2010-07-01

    A characteristic of the Western thought is the effort to counter Christian theology through arguments based on scientific discoveries (antirrhetic theology). Two objections can be raised against this trait: a) Modern science considers as a fact the future expansions, corrections, even total abolishment of scientific knowledge in the face of new discoveries. Therefore, dogmatic positions must not be based on temporary scientific views. b) Antirrhetic theology is mostly based on out-of-date scientific views of the period 1650-1900, which are not valid any more. The example of modern physics and cosmology is prime among them; in these sciences, the prevailing theories are based on the existence of an imperceptible reality, or on apparently “illogical” (in the sense of classical logic) fundamental properties of matter and its particles in quantum mechanics.

  15. The determinants of female junior high school students' intentions to enroll in elective physical science courses in high school: Testing the applicability of the theory of reasoned action

    Science.gov (United States)

    Koballa, Thomas R., Jr.

    Data were collected from female junior high school students (N=94) to identify the determinants of their intentions to enroll in at least one elective physical science course (e.g., physical science, chemistry physics) in high school. The model used in the study was Fishbein and Ajzen's Theory of Reasoned Action. According to the model it is supposed that the intention to perform a certain behavior is a function of the weighted attitude toward performing the behavior and the weighted subjective norm. The effects of external variables (e.g., science grades, academic ability) on females' intentions to enroll in at least one elective physical science course in high school are mediated by the model's theoretical constructs. The findings provide support for several hypotheses derived from the model. The females' intentions to enroll in at least one elective physical science course in high school were found to be a function of both attitude toward performing the behavior and subjective norm. Attitude toward performing the behavior and subjective norm, in combination, were found to predict behavioral intention with a high degree of accuracy. Attitude toward performing the behavior was also found to carry more weight than subjective norm in the multiple regression on behavioral intention. In contrast, academic ability, science grades, and attitude toward science failed to predict behavioral intentions, just as they were unrelated to the females' attitudes toward performing the behavior and subjective norms.

    An individual's motivational orientation serves as a drive to action and can influence their productivity. This study examines how the goal orientation of students towards the pursuit of their graduate degree in physics and chemistry influences their future success outcomes as practicing scientists. Two main orientations are focused on: performance (or ego/ability) orientation and learning (or task/mastery) orientation. The data was obtained as part of Project Crossover, which applied a mixed methodological approach to studying the transition from graduate student to scientist in the physical sciences. Using regression analysis on survey data from 2353 PhD holders in physics and chemistry, we found that individuals exhibiting a learning orientation were more productive than those exhibiting a performance orientation in terms of first-author publications and grant funding. Furthermore, given equal salary, learning-oriented physical scientists produced more first-author publications than average. )

    2015-01-01

    Student learning in instructional physics labs represents a growing area of research that includes investigations of students' beliefs and expectations about the nature of experimental physics. To directly probe students' epistemologies about experimental physics and support broader lab transformation efforts at the University of Colorado Boulder (CU) and elsewhere, we developed the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS). Previous work with this assessment has included establishing the accuracy and clarity of the instrument through student interviews and preliminary testing. Several years of data collection at multiple institutions has resulted in a growing national data set of student responses. Here, we report on results of the analysis of these data to investigate the statistical validity and reliability of the E-CLASS as a measure of students' epistemologies for a broad student population. We find that the E-CLASS demonstrates an acceptable level of both validi...

  1. Vitamin C and common cold incidence: a review of studies with subjects under heavy physical stress.

    Several studies have observed an increased risk of respiratory infections in subjects doing heavy physical exercise. Vitamin C has been shown to affect some parts of the immune system, and accordingly it seems biologically conceivable that it could have effects on the increased incidence of respiratory infections caused by heavy physical stress. In this report the results of three placebo-controlled studies that have examined the effect of vitamin C supplementation on common cold incidence in subjects under acute physical stress are analyzed. In one study the subjects were school-children at a skiing camp in the Swiss Alps, in another they were military troops training in Northern Canada, and in the third they were participants in a 90 km running race. In each of the three studies a considerable reduction in common cold incidence in the group supplemented with vitamin C(0.6-1.0 g/day) was found. The pooled rate ratio (RR) of common cold infections in the studies was 0.50 (95% CI: 0.35-0.69) in favour of vitamin C groups. Accordingly, the results of the three studies suggest that vitamin C supplementation may be beneficial for some of the subjects doing heavy exercise who have problems with frequent upper respiratory infections.

    An experimental study was carried out in 20 squares in the center of Rome, covering a wide range of different uses, sonic environments, geometry, and architectural styles. Soundwalks along the perimeter of each square were performed during daylight and weekdays taking binaural and video recordings, as well as spot measurements of illuminance. The cluster analysis performed on the physical parameters, not only acoustic, provided two clusters that are in satisfactory agreement with the "a priori" classification. Applying the principal component analysis (PCA) to five physical parameters, two main components were obtained which might be associated to two environmental features, namely, "chaotic/calm" and "open/enclosed." On the basis of these two features, six squares were selected for the laboratory audio-video tests where 32 subjects took part filling in a questionnaire. The PCA performed on the subjective ratings on the sonic environment showed two main components which might be associated to two emotional meanings, namely, "calmness" and "vibrancy." The linear regression modeling between five objective parameters and the mean value of subjective ratings on chaotic/calm and enclosed/open attributes showed a good correlation. Notwithstanding these interesting results being limited to the specific data set, it is worth pointing out that the complexity of the soundscape quality assessment can be more comprehensively examined merging the field measurements of physical parameters with the subjective ratings provided by field and/or laboratory tests.

    These original contributions by philosophers and historians of science discuss a range of issues pertaining to the testing of hypotheses in modern physics by observation and experiment. Chapters by Lawrence Sklar, Dudley Shapere, Richard Boyd, R. C. Jeffrey, Peter Achinstein, and Ronald Laymon explore general philosophical themes with applications to modern physics and astrophysics. The themes include the nature of the hypothetico-deductive method, the concept of observation and the validity of the theoretical-observation distinction, the probabilistic basis of confirmation, and the testing of idealizations and approximations.The remaining four chapters focus on the history of particular twentieth-century experiments, the instruments and techniques utilized, and the hypotheses they were designed to test.

This language independent approach adopts the Design-for-All principles, the available international standards for alternative formats and the Universal Design for Learning (UDL) Guidelines. Moreover it supports both static (embossed and refreshable tactile) and dynamic (based on synthetic speech and other sounds) accessibility. It can produce Tactile Books (Embossed Braille and Tactile Graphics), Digital Talking Books (or Digital Audio Books), Large Print Books as well as Acoustic-Tactile Books for the blind and visually impaired students as well as but for the print-disabled. This methodology has been successfully applied in the case of blind students of the Physics, Mathematics and Informatics Departments in the University of Athens.

    1997-12-31

    The ALEGRA shock wave physics code, currently under development at Sandia National Laboratories and partially supported by the US Advanced Strategic Computing Initiative (ASCI), is generic to a certain class of physics codes: large, multi-application, intended to support a broad user community on the latest generation of massively parallel supercomputer, and in a continual state of formal development. To say that the author has ``confidence`` in the results of ALEGRA is to say something different than that he believes that ALEGRA is ``predictive.`` It is the purpose of this talk to illustrate the distinction between these two concepts. The author elects to perform this task in a somewhat historical manner. He will summarize certain older approaches to code validation. He views these methods as aiming to establish the predictive behavior of the code. These methods are distinguished by their emphasis on local information. He will conclude that these approaches are more art than science.

    2010-09-08

    To achieve breakthrough scientific discoveries in the 21st century, a convergence and integration of world-leading experimental facilities and capabilities with theory, modeling, and simulation is necessary. In this issue of Experimental Physical Sciences Vistas, I am excited to present our plans for Los Alamos National Laboratory's future flagship experimental facility, MaRIE (Matter-Radiation Interactions in Extremes). MaRIE is a facility that will provide transformational understanding of matter in extreme conditions required to reduce or resolve key weapons performance uncertainties, develop the materials needed for advanced energy systems, and transform our ability to create materials by design. Our unique role in materials science starting with the Manhattan Project has positioned us well to develop a contemporary materials strategy pushing the frontiers of controlled functionality - the design and tailoring of a material for the unique demands of a specific application. Controlled functionality requires improvement in understanding of the structure and properties of materials in order to synthesize and process materials with unique characteristics. In the nuclear weapons program today, improving data and models to increase confidence in the stockpile can take years from concept to new knowledge. Our goal with MaRIE is to accelerate this process by enhancing predictive capability - the ability to compute a priori the observables of an experiment or test and pertinent confidence intervals using verified and validated simulation tools. It is a science-based approach that includes the use of advanced experimental tools, theoretical models, and multi-physics codes, simultaneously dealing with multiple aspects of physical operation of a system that are needed to develop an increasingly mature predictive capability. This same approach is needed to accelerate improvements to other systems such as nuclear reactors. MaRIE will be valuable to many national

    Physical inactivity and childhood obesity are prevalent in American children, with increased vulnerability in minority, low-resource populations. The aim of this study was to quantify the impact of physical education (PE) on in-school physical activity quantity and intensity in urban minority children attending public elementary schools. This observational study included elementary children (N=212; mean age, 9.9 years; 81.7% black) in Grades 2-5 attending urban public schools with high eligibility for the National School Lunch Program. In-school physical activity was quantified during 4 school weeks across 4 months (January-April 2012) using Omron HJ-151 accelerometer-pedometers. Fitness was assessed with the 20-meter Progressive Aerobic Cardiovascular Endurance Run. Data were analyzed in 2013 using generalized estimating equations to determine the influence of PE and sex on total in-school steps and moderate to vigorous physical activity (MVPA) steps. Based on 3,379 observation days (mean, 15.9 school days/student), students achieved higher in-school physical activity on days with PE (4,979 steps) than on days without PE (3,683 steps, pschool and MVPA steps in urban minority elementary children. PE as a core subject can provide opportunities for urban, minority public school children in low-resource areas to achieve age-appropriate physical activity and fitness goals.

    Directory of Open Access Journals (Sweden)

    Oscar Koopman

    2016-04-01

    Full Text Available This article narrates the lived experiences of a Physical Science teacher named Thobani (pseudonym in implementing a new curriculum in South Africa. Drawing on the work of Husserl and Heidegger, the article describes the objects of direct experience in Thobani’s consciousness about his life as a learner and teacher as revealed during an in-depth semi-structured interview conducted from two perspectives. The genealogical part of the interview chronicled how his knowledge of Physical Science had unfolded in his life as a learner and subsequently as a teacher; the portraiture perspective recounted the often traumatic events of his personal life and the circumstances that had informed his decision to become a teacher. Theoretically, the findings reveal how an incompetent Physical Science teacher had hampered his understanding of the fundamentals of the subject, and how the lack of support from the Department of Education and his head of department had retarded the implementation process. The insights gleaned from this phenomenological investigation into the thought processes of a teacher introduced to a new curriculum could have potentially transformative effects for policy-makers, curriculum planners and teacher educators at a time when South African teachers are yet again faced with the implementation of a new curriculum.

  12. The Persistent Dearth of Women in the Physical Sciences

    Urry, C. Megan

    2002-04-01

    For twenty years, scientists and society alike have averred that discrimination against women is a thing of the past, which may be largely true for the most overt kind of discrimination. Yet judging from the scarcity of women in the physical sciences in the U.S. today, it is clear that these professions efficiently filter out women (and probably other minorities). Not only are women present in much smaller numbers than men at all levels, their presence decreases with increasing rank in the academic hierarchy, and women advance more slowly and with greater attrition than men. Notably, the pre-college pipeline is no longer the critical issue, since women are present in large numbers in introductory science and math classes at top undergraduate institutions. However, there is little agreement on what the critical problem might be, much less its solution. Furthermore, most physical scientists in academia, which is to say male full professors, have paid relatively little attention to this problem and are not well informed about the current status of women in their fields or the extensive research on gender bias. I review the relevant statistics and some of this research. I conclude that progress is possible if people in positions of power adopt the inclusion of women as a priority. This will enhance excellence in our profession, both because it taps a wider pool of talent and because it corrects the bias that has (under the assumption of equal distribution of talent among men and women) excluded some of our best scientists.

    Full Text Available This paper explores complexities and constraints affecting performance and output of physical science learners in Vhembe District, Limpopo Province, South Africa. The study was motivated by the desire of the researcher to establish, profile and characterise the complexities and constraints reminiscence of poor performance of learners in physical science as measured through end-of-year Grade 12 (final year of high school education examination results. Twenty six schools (n=26 were purposively selected from three circuits of education (n=3. From these schools, two learners were randomly selected (n=52 for interviews. In addition, two circuit managers (n=2 were conveniently selected as part of Key Informant Interviews (KII. For the Focus Group Discussions (FGDs, twelve (n=12 parents were randomly selected to form two groups of six members each. Multi-factor complexities and constraints impeding performance of learners were discovered. Intensive teacher in-service programme is recommended. Community engagement should be encouraged to educate parents on the value of involvement in the education of their children. Free access learner support structures such as Homework and Extra-lessons Assistance Centre (H&EACs should be established.

    Machine learning is the science of using computers to find relationships in data without explicitly knowing or programming those relationships in advance. Often without realizing it, we employ machine learning every day as we use our phones or drive our cars. Over the last few years, machine learning has found increasingly broad application in the physical sciences. This most often involves building a model relationship between a dependent, measurable output and an associated set of controllable, but complicated, independent inputs. The methods are applicable both to experimental observations and to databases of simulated output from large, detailed numerical simulations. In this tutorial, we will present an overview of current tools and techniques in machine learning - a jumping-off point for researchers interested in using machine learning to advance their work. We will discuss supervised learning techniques for modeling complicated functions, beginning with familiar regression schemes, then advancing to more sophisticated decision trees, modern neural networks, and deep learning methods. Next, we will cover unsupervised learning and techniques for reducing the dimensionality of input spaces and for clustering data. We'll show example applications from both magnetic and inertial confinement fusion. Along the way, we will describe methods for practitioners to help ensure that their models generalize from their training data to as-yet-unseen test data. We will finally point out some limitations to modern machine learning and speculate on some ways that practitioners from the physical sciences may be particularly suited to help.

    This study examined the associations of subjective and objective measures of the neighbourhood environment with the transportation physical activity of community-dwelling older persons in Singapore. A modified version of the Neighborhood Environment Walkability Scale (NEWS) and Geographical Information System (GIS) measures of the built environment characteristics were related to the frequency of walking for transportation purpose in a study sample of older persons living in high-density apartment blocks within a public housing estate in Singapore. Relevant measured variables to assess the complex relationships among built environment measures and transportation physical activity were examined using structural equation modelling and multiple regression analyses. The subjective measures of residential density, street connectivity, land use mix diversity and aesthetic environment and the objective GIS measure of Accessibility Index have positively significant independent associations with transportation physical activity, after adjusting for demographics, socio-economic and health status. Subjective and objective measures are non-overlapping measures complementing each other in providing information on built environment characteristics. For elderly living in a high-density urban neighborhood, well connected street, diversity of land use mix, close proximity to amenities and facilities, and aesthetic environment were associated with higher frequency of walking for transportation purposes.

    Full Text Available Purpose: To compare the subjective and objective physical function scores of patients with Chronic Low Back Pain (CLBP. Method: A cross- sectional survey design was used. Fifty-one patients with CLBP of mechanical origin were recruited from the physiotherapy out patient clinics of the University of Nigeria Teaching Hospital and the National Orthopedic Hospital both in Enugu, Nigeria. The box numerical scale, Roland-Morris Questionnaire (RMQ-24 and the Back Performance Scale (BPS were used to assess the present pain intensity, the subjective and objective functional status of the participants respectively. Pearson correlation was used to determine relationships. Multiple Regressions were used to determine the predictors of objective function. Alpha level was set at 0.5. Results: The mean age and Body Mass Index of the participants were 49.04 ± 14.33 years and 26.57 ± 4.29 kg/m2 respectively. The mean Pain Intensity, subjective disability (RMQ and objective disability (BPS scores were 6.33 ± 2.09, 9.76 ± 5.14 and 6.43 ± 2.9 respectively. Stepwise multiple regressions showed that when all the variables were entered only marital status was a significant predictor of objective physical function. Conclusion: There is no significant association between subjective and objective functions in patients with CLBP. However, marital status (married is a significant predictor of objective function in CLBP.

    Type 2 diabetes mellitus (T2DM) incidence has been increasing worldwide along with the rise of obesity and sedantery lifestyle. Decreased physical activity (PA) and obesity have also been associated with the low vitamin D levels. We aimed to determine the association between PA, vitamin D status and insulin resistance in overweight and obese subjects. A total of 294 (186 female, 108 male) overweight or obese subjects were included in this cross-sectional study. 25-hydroxy vitamin D (25(OH)D), insulin, fasting plasma glucose (FPG) and HbA1c levels were measured in blood samples. Body mass index (BMI), HOMA-index and total score of International Physical Activity Questionnaire-long form (IPAQ) were calculated. Insulin resistant subjects were compared with the non-resistant group. The mean age of the participants was 45 ± 12.25 and 41.39 ± 10.32; 25(OH)D levels were 8.91 ± 4.30 and 17.62 ± 10.47 ng/dL; BMIs were 31.29 ± 4.48 and 28.2 ± 3.16 kg/m², IPAQ total scores were 548.71 ± 382.81 and 998 ± 486.21 in the insulin resistant and nonresistant subjects, respectively. There was a statistically significant difference in terms of 25(OH)D, FPG, insulin levels, IPAQ total score and BMI between the two groups (p = 0.001, p = 0.001, p = 0.001, p = 0.001, p = 0.001).Significantly low 25(OH)D levels, high BMI and low PA in insulin resistant subjects confirm the importance of active lifestyle and the maintenance of normal vitamin D levels in overweight and obese subjects in prevention of T2DM.

    nature of science and what is the balance of ethnic diversity in the participants in science (students and scientists) in physical science textbooks? To establish an answer to these questions, this investigation used content analysis. For the balance of the four aspects of the nature of science, the analysis was conducted on random page samples of five physical science textbooks. A random sampling of the pages within the physical science textbooks should be sufficient to represent the content of the textbooks (Garcia, 1985). For the balance of ethnic diversity of the participants in science, the analysis was conducted on all pictures or drawings of students and scientists within the content of the five textbooks. One of these IPC books is under current use in a large, local school district and the other four were published during the same, or similar, year. Coding procedures for the sample used two sets of coders. One set of coders have previously analyzed for the nature of science in a study on middle school science textbooks (Phillips, 2006) and the coders for ethnic diversity are public school teachers who have worked with ethnically diverse students for over ten years. Both sets of coders were trained and the reliability of their coding checked before coding the five textbooks. To check for inter-coder reliability, percent agreement, Cohen's kappa and Krippendorff's alpha were calculated. The results from this study indicate that science as a body of knowledge and science as a way of investigating are the prevalent themes of the nature of science in the five physical science textbooks. This investigation also found that there is an imbalance in the ethnic diversity of students and scientists portrayed within the chapters of the physical science textbooks studied. This imbalance reflects ratios that are neither equally balanced nor in align with the U.S. Census. Given that textbooks are the main sources of information in most classrooms, the imbalance of the nature of

    CERN Document Server

    Garcia, Narciso

    1991-01-01

    This text is the product of several years' effort to develop a course to fill a specific educational gap. It is our belief that computer science students should know how a computer works, particularly in light of rapidly changing tech­ nologies. The text was designed for computer science students who have a calculus background but have not necessarily taken prior physics courses. However, it is clearly not limited to these students. Anyone who has had first-year physics can start with Chapter 17. This includes all science and engineering students who would like a survey course of the ideas, theories, and experiments that made our modern electronics age possible. This textbook is meant to be used in a two-semester sequence. Chapters 1 through 16 can be covered during the first semester, and Chapters 17 through 28 in the second semester. At Queens College, where preliminary drafts have been used, the material is presented in three lecture periods (50 minutes each) and one recitation period per week, 15 weeks p...

    Full Text Available Objective. The aims of this study were to (1 assess physical activity and weight status differences and (2 explore the direction and shape of subjective social status (SSS association with physical activity and weight status within four Asian countries. Methods. Cross section data of adult respondents from the nationally representative East Asian Social Survey were used for analyses. Logistic regression stratified by gender was conducted for the first aim, and simple and quadratic logistic regression models were used for the second. Results. SSS was significantly associated with odds of weekly or daily physical activity across all countries and genders, except for South Korean and Japanese females. Quadratic models provided significantly better fit for Chinese males (LR (d.f. = 1 = 6.51, P value <.05 and females (LR (d.f. = 1 = 7.36, P value <.01, South Korean males (LR (d.f. = 1 = 4.40, P value <.05, and Taiwanese females (LR (d.f. = 1 = 4.87, P value <.05. Conclusions. This study provides a comparable cross Asian country measure of moderate-to-vigorous physical activity and new findings that a connection exists between SSS and physical activity. Differences of class distinction help explain the different shaped SSS relationships.

    Full Text Available The objective of this study was to compare anthropometric variables (body weight, height, and percent body fat and plantarflexion and dorsiflexion range of motion (ROM between three different groups of women: classical ballet dancers (n=14, volleyball players (n=22 and physically active subjects (n=13. The assumption was that different functional requirements should produce differences in the anthropometric variables and ROM between the three groups. Body weight and height were higher in volleyball players (66.42 ± 5.8 kg; 174.77 ± 5.6 cm, followed by physically active women (59.93 ±10.3 kg; 164 ± 7.5 cm and ballet dancers (49.25 ± 4.5 kg; 157.03 ± 3.6 cm (p<0.05. Percent body fat was higher in physically active women (30.67 ± 4.6% compared to theother two groups, which showed similar percentages (volleyball players: 24.93 ± 4.1%; ballet dancers: 21.94 ± 4.3%. The three groups were similar in terms of total ankle ROM and active dorsiflexion ROM between the right and left sides. However, plantarflexion ROM was higher in ballet dancers (~83°, followed by physically active women (~68° and volleyball players who presented the smallest ROM (~60°. The different requirements imposed by the three distinct physical activities seem to be responsible for changes in some of the anthropometric variables and ankle joint ROM.

    To address concerns about worker exposures on the Physical Science Laboratory (PSL) rooftop, a tracer study was conducted to measure gaseous tracer concentrations downwind of six stacks on the southern half of the PSL building (PSL-1). These concerns were raised, in part, due to the non-standard configuration of the stacks on this building. Five of the six stacks were only about 8 feet tall, with one shorter stack that was essentially level with the roof deck. These stacks were reconfigured in August 2016, and these exhaust points on PSL-1 are now 18 feet tall. This report describes the objectives of the tracer tests performed on PSL-1, provides an overview of how the tests were executed, and presents results of the tests. The tests on the PSL rooftop were a follow-on project from a similar study performed on the LSL-II ventilation exhaust (Flaherty and Antonio, 2016).

    Full Text Available In this article there is observed e-learing study support in subjects focused on physics, mainly in praktikum of these subjects. Teaching e-learning software made by collective of physics teachers at Mendel university in Brno is possible to use as a electronic exercise book, homework aid for solving of laboratory homework, dataprojector presentation in teaching and also as a examination of students by means of didactic tests. It is necessary to be mindful that programme is valid, simplify studying and also to raise deeper interest in physics. The goal of teaching aid is to simplify studying process and create possibility for teachers to devote all students to a higher extent. Important fact is of course contribution such a support for students themselves. E-learning support can be very valuable, highly developed and contributive but if it is not accepted by all students, all devoted lessons for its creation would be useless. That is why it is very important to monitor regular feedback of students who have a chance to use these supports, afterwords to adapt them according to actual both teachers requests and mainly students requests. It is also very suitable if students have a chance to make a choice among several study supports because not all students are same.

    Circulating oxidative stress and pro-inflammatory markers change after regular physical exercise; however, how a short session of acute physical activity affects the inflammatory status and redox balance in sedentary individuals is still unclear. Aim of this study is to assess antioxidant and inflammatory parameters, both at rest and after acute exercise, in sedentary young men with or without obesity. Thirty sedentary male volunteers, aged 20-45 (mean age 32 ± 7 years), were recruited, divided into 3 groups (normal weight: BMI group comparisons demonstrated significantly higher Glutathione Reductase activity in severely obese subjects in the post-exercise period (P = 0.036), and higher EGF levels in normal weight individuals, either before (P = 0.003) and after exercise (P = 0.05). Intra-group comparisons showed that the acute exercise stress induced a significant increase in Glutathione Reductase activity in severely obese subjects only (P = 0.007), a significant decrease in MCP-1 in the normal weight group (P = 0.02), and a decrease in EGF levels in all groups (normal weight: P = 0.025, overweight/moderate obesity: P = 0.04, severe obesity: P = 0.018). Altogether, these findings suggest that in sedentary individuals with different ranges of BMI, Glutathione Reductase and distinct cytokines are differentially involved into the adaptive metabolic changes and redox responses induced by physical exercise. Therefore, these biomarkers may have the potential to identify individuals at higher risk for developing diseases pathophysiologically linked to oxidative stress.

    Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

    2006-02-01

    The Texas Higher Education Coordinating Board Teacher Quality Grants, supported through No Child Left Behind, are intended to ensure that secondary teachers of specific subjects are "highly qualified". Now in their third year, these grants have done much to shape long-term professional development for teachers in the physical sciences at the University of Texas at Dallas (UTD). The grants have also created a suite of challenges and benefits for the UTD Science Education M.A.T. program. Teacher Quality Grants are based on the No Child Left Behind framework that requires teachers to be "highly qualified" as defined by the state. Recruitment is required to be targeted at teachers who are uncertified or teach one or more classes out of their content area and who work in high needs local school districts. Many of the students brought into our program through these grants have incoming content knowledge in physics similar to that typical of undergraduate non-majors, and a large percentage are uncomfortable with basic mathematics as well. How and what we teach has been dramatically impacted by the Teacher Quality Grants, as have our assessments and evaluations. An ongoing challenge has been to implement a Physics Education Research (PER)-based course design while meeting the specific requirements of the Teacher Quality Grant program. The Teacher Quality Grants have also provided a great deal of opportunity to new and existing teachers in our program. A barrier to our teachers, rising tuition costs, has been removed and as a result a mandate has become a doorway of opportunity for physical science teachers.

My comments are organized into three sections: how underrepresented students' experiences in science classrooms are shaped by their peers; how science teachers can help students listen to and learn from one another; and how the subject matter can invite or discourage student participation in science. More specifically, I underscore the need for teachers and students to listen to one another to promote student learning of science. I also highlight the importance of science education researchers and science teachers viewing students both as individuals and as members of multiple groups; women of color, for example, should be understood as similar to and different from each other, from European American women and from ethnic minorities in general.

    The objective of this study was to examine the effect of Norwegian psychomotor physical therapy on subjective health complaints and psychological symptoms. A non-randomized waiting list controlled design was used. Physiotherapists in Norway recruited patients for a treatment group (n = 40) and waiting list control group (n = 22). Patients on the waiting list could only be included for 6 months, as they then started treatment. Symptoms registration was obtained from both groups at baseline and 6 months, and only for the treatment group also at 12 months. The following self-report forms were used; Subjective Health Complaints Inventory (SCH); Beck Depression Inventory-II (BDI-II); Spielberger State-Trait Anxiety Inventory-Trait (STAI-T); Bergen Insomnia Scale (BIS); Fatigue Questionnaire (FQ); Quality of Life Inventory (QOLI); The Client Satisfaction Questionnaire (CSQ). The patients had had widespread and clinically significant health problems for an average of 9 years upon entrance to the study. After 6 months in psychomotor physical therapy, all the measured symptoms in the treatment group were significantly reduced, but only quality of life was significantly reduced when compared to the waiting list control group. After 12 months in therapy, the patients in the treatment group had continued to improve on all measured variables. The symptoms of anxiety and depression, as well as quality of life, were improved from clinical to non-clinical level. Norwegian psychomotor physical therapy seems to have potential for reducing symptoms of subjective health complaints, depression, anxiety, insomnia, fatigue and improving quality of life, although the process takes time. Further research is needed to gain more rigorous data, and randomized controlled studies are highly welcomed. Copyright © 2010 John Wiley & Sons, Ltd.

    The present study examined the potential contribution of meaning in life to the relationship between physical activity and subjective vitality in older adults. Two-hundred and fifty community-dwelling elders completed the instruments assessing physical activity, meaning in life, and subjective vitality. Results from structural equation modeling indicated that physical activity was positively associated with both meaning in life and subjective vitality. Further, the relationship between physical activity and vitality was partially mediated by meaning in life. Although previous studies have consistently found a positive impact of physical activity on vitality, the current study suggested that it is more productive to focus not only on physical activity, but also on meaning in life, in order to vitalize elders. Further, a focus on meaning in life can be a productive way to continue to vitalize older adults who are unable to engage in regular physical activity. Copyright © 2017 Elsevier B.V.

    Contemporary physical science studies rely on the effective analyses of geographically dispersed spatial data and simulations of physical phenomena. Single computers and generic high-end computing are not sufficient to process the data for complex physical science analysis and simulations, which can be successfully supported only through distributed computing, best optimized through the application of spatial principles. Spatial computing, the computing aspect of a spatial cyberinfrastructure, refers to a computing paradigm that utilizes spatial principles to optimize distributed computers to catalyze advancements in the physical sciences. Spatial principles govern the interactions between scientific parameters across space and time by providing the spatial connections and constraints to drive the progression of the phenomena. Therefore, spatial computing studies could better position us to leverage spatial principles in simulating physical phenomena and, by extension, advance the physical sciences. Using geospatial science as an example, this paper illustrates through three research examples how spatial computing could (i) enable data intensive science with efficient data/services search, access, and utilization, (ii) facilitate physical science studies with enabling high-performance computing capabilities, and (iii) empower scientists with multidimensional visualization tools to understand observations and simulations. The research examples demonstrate that spatial computing is of critical importance to design computing methods to catalyze physical science studies with better data access, phenomena simulation, and analytical visualization. We envision that spatial computing will become a core technology that drives fundamental physical science advancements in the 21st century. PMID:21444779

  5. Teaching Earth Sciences as an interdisciplinary subject: Novel module design involving research literature

    Science.gov (United States)

    Tong, Vincent C. H.

    2010-05-01

    The study of Earth Sciences requires an interdisciplinary approach as it involves understanding scientific knowledge originating from a wide spectrum of research areas. Not only does it include subjects ranging from, for instance, hydrogeology to deep crustal seismology and from climate science to oceanography, but it also has many direct applications in closely related disciplines such as environmental engineering and natural resources management. While research crossing traditional disciplinary boundaries in geosciences is becoming increasingly common, there is only limited integration of interdisciplinary research in the teaching of the subject. Given that the transition from undergraduate education based on subject modules to postgraduate interdisciplinary research is never easy, such integration is a highly desirable pedagogical approach at both undergraduate and postgraduate levels. My presentation is based on a recent teaching project involving novel design of an undergraduate course. The course is implemented in order to address the synergy between research and teaching (Tong, 2009). This project has been shown to be effective and successful in teaching geosciences undergraduates at the University of London. The module consists of studying core geophysical principles and linking them directly to a selection of recently published research papers in a wide range of interdisciplinary applications. Research reviewing and reporting techniques are systematically developed, practised and fully integrated into teaching of the core scientific theories. A fully-aligned assignment with a feedback website invites the students to reflect on the scientific knowledge and the study skills related to research literature they have acquired in the course. This teaching project has been recognized by a teaching award (http://www.clpd.bbk.ac.uk/staff/BETA). In this presentation, I will discuss how undergraduate teaching with a focus on research literature in Earth Sciences can

  7. When physics is not "just physics": complexity science invites new measurement frames for exploring the physics of cognitive and biological development.

    Science.gov (United States)

    Kelty-Stephen, Damian; Dixon, James A

    2012-01-01

    The neurobiological sciences have struggled to resolve the physical foundations for biological and cognitive phenomena with a suspicion that biological and cognitive systems, capable of exhibiting and contributing to structure within themselves and through their contexts, are fundamentally distinct or autonomous from purely physical systems. Complexity science offers new physics-based approaches to explaining biological and cognitive phenomena. In response to controversy over whether complexity science might seek to "explain away" biology and cognition as "just physics," we propose that complexity science serves as an application of recent advances in physics to phenomena in biology and cognition without reducing or undermining the integrity of the phenomena to be explained. We highlight that physics is, like the neurobiological sciences, an evolving field and that the threat of reduction is overstated. We propose that distinctions between biological and cognitive systems from physical systems are pretheoretical and thus optional. We review our own work applying insights from post-classical physics regarding turbulence and fractal fluctuations to the problems of developing cognitive structure. Far from hoping to reduce biology and cognition to "nothing but" physics, we present our view that complexity science offers new explanatory frameworks for considering physical foundations of biological and cognitive phenomena.

    Meyer, Andreas; Egry, Ivan

    2011-12-01

    ISPS is the major international scientific forum for researchers in physics utilizing the space environment, in particular microgravity. It is intended to inspire and encourage cross-cutting discussions between different scientific communities working in the same environment. Contributions discussing results of experiments carried out on drop towers, parabolic aircraft flights, sounding rockets, unmanned recoverable capsules and, last but not least, the International Space Station ISS, are the backbone of this conference series, complemented by preparatory ground-based work, both experimentally and theoretically. The first International Symposium on Physical Sciences in Space (ISPS) sponsored by the International Microgravity Strategic Planning Group (IMSPG) took place in 2000 in Sorrento, Italy. IMSPG seeks to coordinate the planning of space for research in physical sciences by space agencies worldwide. AEB (Brazil), ASI (Italy), CNES (France), CSA (Canada), DLR (Germany), ESA (Europe), JAXA (Japan), NASA (USA), NSAU (Ukraine) and RSA (Russia) are members, and CNSA (China) and ISRO (India) are also invited to join IMSPG meetings. ISPS-4 was the fourth symposium in that series, following ISPS-2 organized by CSA in 2004 in Toronto, Canada, and ISPS-3 organized in 2007 by JAXA in Nara, Japan. ISPS-4 was jointly organized by ESA and DLR on behalf of the IMSPG and was held in Bonn from 11-15 July 2011. 230 participants from 17 different countries attended ISPS-4. Recent microgravity experiments were presented, analysed, and set in context to results from Earth bound experiments in 16 plenary and 68 topical talks. Lively discussions continued during two dedicated poster sessions and at the exhibition booths of space industry and research centers with new flight hardware on display. The oral presentations at ISPS4 were selected exclusively on the basis of scientific merit, as evidenced through the submitted abstracts. The selection was performed by the International

  10. Effect of science teaching on the young child's concept of piagetian physical causality: Animism and dynamism

    Science.gov (United States)

    Wolfinger, Donna M.

    The purpose of this research was to determine whether the young child's understanding of physical causality is affected by school science instruction. Sixty-four subjects, four and one-half through seven years of age, received 300 min of instruction designed to affect the subject's conception of causality as reflected in animism and dynamism. Instruction took place for 30 min per day on ten successive school days. Pretesting was done to allow a stratified random sample to be based on vocabulary level and developmental stage as well as on age and gender. Post-testing consisted of testing of developmental level and level within the causal relations of animism and dynamism. Significant differences (1.05 level) were found between the experimental and control groups for animism. Within the experimental group, males differed significantly (1.001 level) from females. The elimination of animism appeared to have occurred. For dynamism, significant differences (0.05 level) were found only between concrete operational subjects in the experimental and control groups, indicating a concrete level of operations was necessary if dynamism was to be affected. However, a review of interview protocols indicated that subjects classified as nonanimistic had learned to apply a definition rather than to think in a nonanimistic manner.

  12. Topics in Complexity: From Physical to Life Science Systems

    Science.gov (United States)

    Charry, Pedro David Manrique

    Complexity seeks to unwrap the mechanisms responsible for collective phenomena across the physical, biological, chemical, economic and social sciences. This thesis investigates real-world complex dynamical systems ranging from the quantum/natural domain to the social domain. The following novel understandings are developed concerning these systems' out-of-equilibrium and nonlinear behavior. Standard quantum techniques show divergent outcomes when a quantum system comprising more than one subunit is far from thermodynamic equilibrium. Abnormal photon inter-arrival times help fulfill the metabolic needs of a terrestrial photosynthetic bacterium. Spatial correlations within incident light can act as a driving mechanism for an organism's adaptation toward more ordered structures. The group dynamics of non-identical objects, whose assembly rules depend on mutual heterogeneity, yield rich transition dynamics between isolation and cohesion, with the cohesion regime reproducing a particular universal pattern commonly found in many real-world systems. Analyses of covert networks reveal collective gender superiority in the connectivity that provides benefits for system robustness and survival. Nodal migration in a network generates complex contagion profiles that lie beyond traditional approaches and yet resemble many modern-day outbreaks.

  13. Physical activity, screen time and the risk of subjective health complaints in school-aged children.

    2017-03-01

    Internationally, subjective health complaints have become increasingly prevalent in children. Thus, a comprehensive understanding of the determinants of health complaints is needed to inform effective policies and strategies. This study explores if meeting physical activity and total screen time (TST) recommendations are associated with the risk of reporting health complaints weekly or more. The 2014 Irish Health Behaviour in School-aged Children study collected questionnaire data from 10,474 10-17year olds. Children reported how often they experienced eight health complaints as less than weekly or weekly or more. Children who met moderate-to-vigorous physical activity recommendations were active for 60min/day in the past seven days. Three types of screen based activity were categorised to reflect if children met TST recommendations of ≤2h/day. Poisson regression examined the association between meeting recommendations and the risk of health complaints. The prevalence of individual health complaints ranged from 20.4-44.3% in girls and from 10.1-35.4% in boys. Overall, 5.1% (4.5-5.6%) of girls and 8.7% (7.8-9.5%) of boys met both (physical activity and TST) recommendations, while two thirds of girls (67.3%, 66.1-68.5%) and over half of boys (55.0%, 53.5-56.6%) met neither recommendation. Not meeting TST recommendations was significantly associated with the risk of reporting health complaints while associations with physical activity were less apparent. Children who did not meet either recommendation had a significantly increased risk for six of the health complaints when compared to those who met both recommendations. As health complaints and poor lifestyle behaviours were common in children, population level measures are warranted. Copyright © 2016 Elsevier Inc. All rights reserved.

  14. History of Science in Physics Teaching: A Study About the Teaching of Gravitational Attraction Developed Among Prospective Teachers

    2010-03-01

    Full Text Available We report here some outcomes of a research related to a didactical experience aiming to integrate the History of Science to the Physics Teaching, taking as background the historical development of the gravitational attraction. The research, of qualitative approach, is a case study and it was carried out in a sample of eleven students belonging to an undergraduate physics program (called licenciatura in Brazil designed to from High School physics teachers in a São Paulo State Public University. We tried initially to reveal prospective teachers’ conceptions in order to provide a prepare that was used to guide the activities from the reality’s diagnosis. The aim was to promote discussions on the existence and persistence of alternative conceptions, on the historical evolution of the subject gravitational attraction, through readings and debates of texts contemplating recent subjects on the Science Education research, in order to generate dissatisfaction with traditional teaching models. The future High School physics teachers were asked to construct their own teaching proposal, through the development, in real situations, in a High School, of a mini-course based on: debates and synthesis developed in University classroom, the History of the Science and the student’s alternative conceptions. In this paper we will analyze future teachers’ alternative conceptions, the development of the course proposed, and details of the mini-courses taught by the prospective teachers in real situations, among High School students, its coherence and the posture changes observed in them.

  15. The material co-construction of hard science fiction and physics

    Science.gov (United States)

    Hasse, Cathrine

    2015-12-01

    This article explores the relationship between hard science fiction and physics and a gendered culture of science. Empirical studies indicate that science fiction references might spur some students' interest in physics and help develop this interest throughout school, into a university education and even further later inspire the practice of doing science. There are many kinds of fiction within the science fiction genre. In the presented empirical exploration physics students seem particularly fond of what is called `hard science fiction': a particular type of science fiction dealing with technological developments (Hartwell and Cramer in The hard SF renaissance, Orb/TOR, New York, 2002). Especially hard science fiction as a motivating fantasy may, however, also come with a gender bias. The locally materialized techno-fantasies spurring dreams of the terraforming of planets like Mars and travels in time and space may not be shared by all physics students. Especially female students express a need for other concerns in science. The entanglement of physics with hard science fiction may thus help develop some students' interest in learning school physics and help create an interest for studying physics at university level. But research indicates that especially female students are not captured by the hard techno-fantasies to the same extent as some of their male colleagues. Other visions (e.g. inspired by soft science fiction) are not materialized as a resource in the local educational culture. It calls for an argument of how teaching science is also teaching cultural values, ethics and concerns, which may be gendered. Teaching materials, like the use of hard science fiction in education, may not just be (yet another) gender bias in science education but also carrier of particular visions for scientific endeavours.

    This study compared subjective with objective sleep parameters among 72 physical education students. Furthermore, the study determined whether 24-hr recording differs from nighttime recording only. Participants wore the SenseWear Armband™ for three consecutive nights and kept a sleep log. Agreement rates ranged from moderate to low for sleep onset latency (ICC = 0.39 to 0.70) and wake after sleep onset (ICC = 0.22 to 0.59), while time in bed (ICC = 0.93 to 0.95) and total sleep time (ICC = 0.90 to 0.92) revealed strong agreement during this period. Comparing deviations between 24-hr wearing time (n = 24) and night-only application (n = 20) revealed no statistical difference (p > 0.05). As athletic populations have yet to be investigated for these purposes, this study provides useful indicators and practical implications for future studies.

    Stevens, Stacy Mckimm

    There has been much research to suggest that a single-sex college experience for female undergraduate students can increase self-confidence and leadership ability during the college years and beyond. The results of previous studies also suggest that these students achieve in the workforce and enter graduate school at higher rates than their female peers graduating from coeducational institutions. However, some researchers have questioned these findings, suggesting that it is the selectivity level of the colleges rather than the comprised gender of the students that causes these differences. The purpose of this study was to justify the continuation of single-sex educational opportunities for females at the post-secondary level by examining the effects that college selectivity, college type, and time have on the rate of undergraduate females pursuing majors in non-traditional fields. The study examined the percentage of physical science, life science, math and computer science, and social science degrees conferred upon females graduating from women's colleges from 1985-2001, as compared to those at comparable coeducational colleges. Sampling for this study consisted of 42 liberal arts women's (n = 21) and coeducational (n = 21) colleges. Variables included the type of college, the selectivity level of the college, and the effect of time on the percentage of female graduates. Doubly multivariate repeated measures analysis of variance testing revealed significant main effects for college selectivity on social science graduates, and time on both life science and math and computer science graduates. Significant interaction was also found between the college type and time on social science graduates, as well as the college type, selectivity level, and time on math and computer science graduates. Implications of the results and suggestions for further research are discussed.

  16. Sex, Class, and Physical Science Educational Attainment: Portions due to Achievement Versus Recruitment

    Simon, Richard M.; Farkas, George

    Nationally representative data from the National Education Longitudinal Study are used to investigate why males (rather than females) and children of parents with advanced degrees (rather than those from less-educated parents) are more highly represented among physical science bachelor's degrees and graduate students. Parental education is measured by three categories: neither parent has a bachelor's degree, at least one parent has a bachelor's degree, or at least one parent has a degree beyond the bachelor's. Physical science is defined as students majoring in physics, engineering, mathematics, or computer science. The effects of mathematics achievement and effects not accounted for by mathematics achievement (what the authors call "recruitment" effects) are isolated for parental education categories and for sex, allowing inequality in physical science degree attainment to be decomposed into portions due to achievement and portions due to recruitment. Additionally, the results from logistic regressions predicting the attainment of a bachelor's degree in physical science as well as the pursuit of a graduate degree in physical science are presented. It is found that for parental education categories, the gaps in physical science educational attainment are nearly entirely accounted for by differences in mathematics achievement, suggesting that if achievement could be equalized, physical science educational attainment differences among parental education categories would disappear. However, the sex gap in physical science educational attainment operates almost entirely independent of achievement effects, suggesting that if the mathematics achievement distributions of males and females were identical, the sex gap in physical science educational attainment would be unchanged from what it is today.

    Shared residence after divorce is rising in most Western countries and legally recommended by law in Belgium since 2006. Living with both parents after divorce is assumed to increase children's well-being, through a better parent-child relationship, but may also be stressful, as children live in 2 different family settings. In this study, we investigate whether the association between the residential arrangement of adolescents and 3 measures of subjective well-being (depressive feelings, life satisfaction, and self-esteem) is moderated by the Big Five personality factors. The sample is selected from the national representative Divorce in Flanders study and contains information about 506 children from divorced parents between 14- and 21-years-old. Our findings indicated a consistent pattern of interactions between conscientiousness and joint physical custody for 2 of the 3 subjective well-being indicators. The specific demands of this residential arrangement (making frequent transitions, living at 2 places, adjustment to 2 different lifestyles, etc.) may interfere with the nature of conscientious adolescents: being organized, ordered, and planful. Our results showed support for a Person × Environment interaction, and demonstrate the need for considering the individual characteristics of the child when settling postdivorce residential arrangements.

    The purpose of this study was to investigate the moderator effects of autonomous motivation on the relationship between subjective well-being and physical health. Using a cluster sampling approach 486 students (403 female and 83 male students) were included in this study. Subjective well-being, physical health and autonomous motivation were determined by self-report measures. Data were analysed using hierarchical regression analysis and analysis of variance. The results show that high self-determination moderates the relationship between high subjective well-being and physical health. Accordingly, the best physical health was reported by participants who had high level of subjective well-being and whose behaviours were self-determined. Additional analyses have shown that the moderating effect of self-determination is based on the moderational impact of autonomous motives and not the controlling ones. Additionally, whether autonomous motivation moderates the relationship between components of subjective well-being and physical health was also tested. The findings have shown that autonomous motives moderate relationship between physical health and one component of well-being, positive affect. Consequently, a good physical health was found among participants with high positive affect and behaviours regulated by high degree of autonomous motives. Conclusion which can be drawn from these findings is that if an individual behaves autonomously then it can contribute to positive mind-body influences and support their own health.

    In Mexico exist due to the lack of water in the City, which is where the College of Sciences and Humanities Orient (at UNAM) is located. This is because a point of view from the Chemical, Physics and Biology subjects is important to find learning strategies that motivate students to seek solutions to problems such as these. As Science Mentors, students were asked to propose water treatment from the homes they live in. From these investigations the students concluded that it was necessary to study in depth the wetlands like Multi-trophic Aquatic System that allow the treatment of gray water, so that a prototype of Micro-scale Multitrophic Aquatic System was set up in the laboratory, where the pH was measured , The concentration of oxygen, phosphates, from a Chemical perspective. As for the subject of Biology, we worked on the search for mycorrhizal fungi associated with the growth of plants for the purification of water. In physics we worked the sedimentation system. Artificial wetlands are man-made zones in which, in a controlled manner, mechanisms for the removal of contaminants present in wastewater, occurring in natural wetlands through physical, biological and chemical processes, are constructed mechanically and Is waterproofed to prevent losses of water to the subsoil, the use of substrates different from the original land for rooting the plants and their selection that will colonize the wetland benefit the recovery of water. The present project aims to structure an Artificial Wetland to carry out didactic strategies, activities with students, as well as work on research projects in the sciences of Chemistry, Physics and Biology. Through the application of chemical, biological and physical concepts and processes, so that students of the different semesters of the College of Sciences and Humanities Plantel Oriente, appropriate the relevant knowledge in the area of experimental sciences, developing thinking skills and achieve Significant learning, which are

    Full Text Available Abstract Background Short and valid measures of the impact of a stroke on integration are required in health and social settings. The Subjective Index of Physical and Social Outcome (SIPSO is one such measure. However, there are questions whether scores can be summed into a total score or whether subscale scores should be calculated. This paper aims to provide clarity on the internal construct validity of the subscales and the total scale. Methods SIPSO data were collected as part of two parallel surveys of the met and unmet needs of 445 younger people (aged 18-65 with non-recent stroke (at least one year and living at home. Factor, Mokken and Rasch analysis were used. Results Factor analysis supported a two factor structure (explaining 68% of the variance as did the Mokken analysis (overall Loevinger coefficient 0.77 for the Physical Integration subscale; 0.51 for the Social Integration subscale. Both subscales fitted the Rasch model (P > 0.01 after adjusting for some observed differential item functioning. The 10-items together did not fit the Rasch model. Conclusions The SIPSO subscales are valid for use with stroke patients of working age but the total SIPSO is not. The conversion table can be used by clinicians and researchers to convert ordinal data to interval level prior to mathematical operations and other parametric procedures. Further work is required to explore the occurrence of bias by gender for some of the items.

  7. A mixed-age science collaborative between elementary and high school physics students: A study of attitude toward school science and inquiry skill

    Blain, Mary Perron

    Grade three students had significant improvements in inquiry ability and attitude toward school science as a function of their participation in mixed-age dyads completing inquiry-based science experiments with a high school physics partner. The social interaction between the 'more capable other' (Vygotsky, 1978) with the grade three student in the mixed-age problem solving team indicates a contributing factor in this improvement. This study employed a quasi-experimental design with intact groups of non-random assignment. The non-parametric Wilcoxon test (p = 0.025) was used to analyze scores for each academic achievement group for significant differences pre- and post-collaborative in "Inquiry" skill and "Attitude" toward school science scores. Three grade three classrooms from one elementary school and one high school physics class from the same school district were involved in the study. The high school physics class teamed with one intact grade three class as the mixed-age dyad performing the "hands-on" experiments (treatment). The two grade three classes teamed as same-age peer dyads (comparison group) to perform the same experiments on the same day. Using methods patterned after the way scientists investigate their world, the dyads performed experiments considered for future grade three national assessments (NAEP, 1994), i.e. "Which paper towel holds the most water?"; "Which magnet is stronger?"; "Which type of sugar, cubed or loose, dissolves best in warm water?" Trained raters scored the written lab reports using standardized scoring guides and characteristic benchmark responses to determine the "Inquiry" skill score for each subject. The "Attitude" toward school science score for each subject was determined from the Likert scale survey, Individual and Group Attitudes Toward Science and the open-ended Sentence Completion Test (SCT) (Piburn & Sidlick, 1992). Three raters scored the SCT survey for each subject. This study showed that for a grade three student

    Full Text Available There are many hypotheses regarding factors that may encourage female students to pursue careers in the physical sciences. Using multivariate matching methods on national data drawn from the Persistence Research in Science and Engineering (PRiSE project (n=7505, we test the following five commonly held beliefs regarding what factors might impact females’ physical science career interest: (i having a single-sex physics class, (ii having a female physics teacher, (iii having female scientist guest speakers in physics class, (iv discussing the work of female scientists in physics class, and (v discussing the underrepresentation of women in physics class. The effect of these experiences on physical science career interest is compared for female students who are matched on several factors, including prior science interests, prior mathematics interests, grades in science, grades in mathematics, and years of enrollment in high school physics. No significant effects are found for single-sex classes, female teachers, female scientist guest speakers, and discussing the work of female scientists. However, discussions about women’s underrepresentation have a significant positive effect.

    Physical phantoms are essential for the development, optimization, and evaluation of x-ray breast imaging systems. Recognizing the major effect of anatomy on image quality and clinical performance, such phantoms should ideally reflect the three-dimensional structure of the human breast. Currently, there is no commercially available three-dimensional physical breast phantom that is anthropomorphic. The authors present the development of a new suite of physical breast phantoms based on human data. The phantoms were designed to match the extended cardiac-torso virtual breast phantoms that were based on dedicated breast computed tomography images of human subjects. The phantoms were fabricated by high-resolution multimaterial additive manufacturing (3D printing) technology. The glandular equivalency of the photopolymer materials was measured relative to breast tissue-equivalent plastic materials. Based on the current state-of-the-art in the technology and available materials, two variations were fabricated. The first was a dual-material phantom, the Doublet. Fibroglandular tissue and skin were represented by the most radiographically dense material available; adipose tissue was represented by the least radiographically dense material. The second variation, the Singlet, was fabricated with a single material to represent fibroglandular tissue and skin. It was subsequently filled with adipose-equivalent materials including oil, beeswax, and permanent urethane-based polymer. Simulated microcalcification clusters were further included in the phantoms via crushed eggshells. The phantoms were imaged and characterized visually and quantitatively. The mammographic projections and tomosynthesis reconstructed images of the fabricated phantoms yielded realistic breast background. The mammograms of the phantoms demonstrated close correlation with simulated mammographic projection images of the corresponding virtual phantoms.

    Physical activity promotes health and longevity. Further elaboration of the role of physical activity for human health in epidemiological studies on large samples requires accurate methods that are easy to use, cheap, and possible to repeat. The use of telecommunication technologies such as cell phones is highly interesting in this respect. In an earlier report, we showed that physical activity level (PAL) assessed using a cell phone procedure agreed well with corresponding estimates obtained using the doubly labeled water method. However, our earlier study indicated high within-subject variation in relation to between-subject variations in PAL using cell phones, but we could not assess if this was a true variation of PAL or an artifact of the cell phone technique. Our objective was to compare within- and between-subject variations in PAL by means of cell phones with corresponding estimates using an accelerometer. In addition, we compared the agreement of daily PAL values obtained using the cell phone questionnaire with corresponding data obtained using an accelerometer. PAL was measured both with the cell phone questionnaire and with a triaxial accelerometer daily during a 2-week study period in 21 healthy Swedish women (20 to 45 years of age and BMI from 17.7 kg/m² to 33.6 kg/m²). The results were evaluated by fitting linear mixed effect models and descriptive statistics and graphs. With the accelerometer, 57% (95% confidence interval [CI] 40%-66%) of the variation was within subjects, while with the cell phone, within-subject variation was 76% (95% CI 59%-83%). The day-to-day variations in PAL observed using the cell phone questions agreed well with the corresponding accelerometer results. Both the cell phone questionnaire and the accelerometer showed high within-subject variations. Furthermore, day-to-day variations in PAL within subjects assessed using the cell phone agreed well with corresponding accelerometer values. Consequently, our cell phone

  6. Practical Strategy on the Subject of “Science and Ethics” for Overcoming Hybrid Engineering Ethics Education

    Science.gov (United States)

    Yasui, Yoshiaki

    The issue of economic globalization and JABEE (Japan Accreditation Board for Engineering Education) mean that education on engineering ethics has now become increasingly important for science-engineering students who will become the next generation of engineers. This is clearly indicated when engineers are made professionally responsible for various unfortunate accidents that happen during daily life in society. Learning hybrid engineering ethics is an essential part of the education of the humanities and sciences. This paper treats the contents for the subject of “Science and Ethics” drawing on several years of practice and the fruits of studying science and engineering ethics at the faculty of science-engineering in university. This paper can be considered to be a practical strategy to the formation of morality.

    Full Text Available Objectives: The aim of the study was to evaluate effects of Finnish sauna bathing on lipid profile in healthy, young men. Material and Methods: Sixteen male subjects (20–23 years were subjected to 10 sauna bathing sessions in a Finnish sauna every 1 or 2 days. The mean sauna temperature was 90±2°C, while humidity was 5–16%. Each session consisted of three 15-minute parts and a 2-minute cool-down between them. The following measurements were taken before and after the sauna sessions: body mass, heart rate, body skinfold thickness. The percentage fat content and then, the lean body mass were calculated. Total cholesterol, triacylglycerols, lipoprotein cholesterol LDL and HDL were measured in blood samples. Results: A statistically significant decrease of total cholesterol and LDL cholesterol was observed during 3 weeks of sauna treatment and in the week afterwards. A significant decline in triacylglycerols was found directly after the 1st and 24 h directly after the 10th sauna session. After the 10th sauna session the level of HDL cholesterol remained slightly increased, but this change was not statistically significant. A decrease in blood plasma volume was found directly after the 1st and the last sauna bathing session due to perspiration. An adaptive increase in blood plasma volume was also found after the series of 10 sauna sessions. Conclusions: Ten complete sauna bathing sessions in a Finnish sauna caused a reduction in total cholesterol and LDL cholesterol fraction levels during the sessions and a gradual return of these levels to the initial level during the 1st and the 2nd week after the experiment. A small, statistically insignificant increase in HDL-C level and a transient decline in triacylglycerols were observed after those sauna sessions. The positive effect of sauna on lipid profile is similar to the effect that can be obtained through a moderate-intensity physical exercise.

    Full Text Available In this study, the pedagogical content knowledge (PCK of four experienced primary school teachers was investigated within the “Let’s Solve the Riddle of Our Body Unit”. The PCK investigation adopted a learning approach based on inquiry, content representation and pedagogical and professional-experience repertoires (PaP-eRs, and interview forms were used as data collection tools. During the course of the research, the findings obtained from observations made during a total of 18 course hours formed the basic data source of the study. According to the results of the study, in which descriptive and content analysis were used concurrently, primary school teachers lack subject matter knowledge, do not interrogate the pre-knowledge of students and some misconceptions exist regarding about blood moves and exercise with pulse. Additionally, some deficiencies were detected in the curriculum, i.e., it offers non-inquisitional knowledge. Furthermore, teachers employee assessment methods with traditional teaching methods and techniques. In the context of an inquiry-based learning approach, teachers appeared to believe that classroom activities were adversely affected by the physical conditions (class size, lack of laboratory etc., students’ cognitive levels and parent profiles. The result of this study revealed that PCK components affect one another. The PCK findings pertaining to primary school teachers as it concerns the unit are briefly discussed and some suggestions about the development of PCK are submitted.

    There are many hypotheses regarding factors that may encourage female students to pursue careers in the physical sciences. Using Propensity Score Matching (PSM) on national data (n=7505) drawn from the Persistence Research in Science and Engineering (PRiSE) project, we test five commonly held beliefs including having a single-sex physics class, having a female physics teacher, having female scientist guest speakers in physics class, discussing the work of women scientists in physics class, and discussing the under-representation of women in physics class. The effect of these experiences is compared for female students who are matched on several factors, including parental education, prior science/math interests, and academic background, thereby controlling for the effect of many confounding variables.

    Full Text Available Many problems that arise in today's society are rooted in the issue of morality as a result of the marginalization of the values of character. To solve this problem, need to be enforced the values of good character on every member of the community, and the proper way is through the educational process, including through education in schools ranging from elementary education to higher education. To find out whether the teachers in elementary schools are ready to take this work, the research conducted to determine the readiness of teachers and the problems associated with its implementation. Through a questionnaire calculated in descriptive percentage on a sample of elementary school teachers who are spread in Semarang, Semarang District and Temanggung, it can be concluded that in teachers’ view it is very important to integrate the learning of characters in the lesson. However, they need guidance /examples to develop learning model with its features, which integrate the values of the characters in the science subject.Banyak persoalan yang timbul di masyarakat dewasa ini berakar pada persoalan moralitas sebagai akibat terpinggirkannya nilai-nilai karakter, Untuk mengatasi persoalan ini, perlu ditegakkan lagi nilai nilai karakter yang baik pada setiap anggota masyarakat, dan cara yang tepat adalah melalui proses pendidikan, di antaranya melalui pendidikan di sekolah mulai dari pendidikan dasar sampai pendidikan tinggi. Untuk mengetahui apakah para guru pada Sekolah Dasar siap mengemban tugas ini, maka diadakan penelitian untuk mengetahui kesiapan para guru dan masalah-masalah yang terkait dengan pelaksanaannya. Melalui angket yang kemudian diolah secara deskriptive persentasi pada sampel guru SD yang tersebar di Kota Semarang, Kabupaten Semarang dan Kabupaten Temanggung, dapat diketahui bahwa para guru menganggap sangat penting untuk mengintegrasikan pembelajaran karakter dalam matapelajaran IPA. Namun demikian mereka membutuhkan bimbingan

  14. The politics of the self: psychological science and bourgeois subjectivity in 19th century Spain

    Directory of Open Access Journals (Sweden)

    Novella, Enric J.

    2010-12-01

    Full Text Available This paper offers an analysis of the process of institutionalization of psychological knowledge in Spain following the educative reforms implemented during the second third of the 19th century, which prescribed its inclusion in the curricular program of the new secondary education. After a detailed examination of the theoretical orientation, the ideological assumptions and the sociopolitical connections of the contents transmitted to the students throughout the century, its militant spiritualism is interpreted as a highly significant attempt on the part of the liberal elites to articulate a pedagogy of subjectivity intended to counteract the trends toward reduction, naturalization and fragmentation of psychic life inherent to the development of modern science.

    En este artículo se ofrece un análisis del proceso de institucionalización del conocimiento psicológico en España por obra de las reformas educativas implementadas durante el segundo tercio del siglo XIX, que prescribieron su inclusión en el programa curricular de la nueva educación secundaria. Tras un examen detenido de la orientación doctrinal, los supuestos ideológicos y la filiación sociopolítica de los contenidos transmitidos a los alumnos durante la mayor parte de la centuria, se interpreta su espiritualismo militante como un intento muy significativo por parte de las élites liberales de articular una pedagogía de la subjetividad destinada a contrarrestar las tendencias de reducción, naturalización y fragmentación del psiquismo alentadas por el desarrollo de la ciencia moderna.

  17. Interests diffusion on a semantic multiplex. Comparing Computer Science and American Physical Society communities

    Science.gov (United States)

    D'Agostino, Gregorio; De Nicola, Antonio

    2016-10-01

    Exploiting the information about members of a Social Network (SN) represents one of the most attractive and dwelling subjects for both academic and applied scientists. The community of Complexity Science and especially those researchers working on multiplex social systems are devoting increasing efforts to outline general laws, models, and theories, to the purpose of predicting emergent phenomena in SN's (e.g. success of a product). On the other side the semantic web community aims at engineering a new generation of advanced services tailored to specific people needs. This implies defining constructs, models and methods for handling the semantic layer of SNs. We combined models and techniques from both the former fields to provide a hybrid approach to understand a basic (yet complex) phenomenon: the propagation of individual interests along the social networks. Since information may move along different social networks, one should take into account a multiplex structure. Therefore we introduced the notion of "Semantic Multiplex". In this paper we analyse two different semantic social networks represented by authors publishing in the Computer Science and those in the American Physical Society Journals. The comparison allows to outline common and specific features.

    2015-01-01

    Full Text Available Background. We determined the extent to which heart rate variability (HRV responses to daily physical activity differ between subjects with and without chronic neck pain. Method. Twenty-nine subjects (13 women with chronic neck pain and 27 age- and gender-matched healthy controls participated. Physical activity (accelerometry, HRV (heart rate monitor, and spatial location (Global Positioning System (GPS were recorded for 74 hours. GPS data were combined with a diary to identify periods of work and of leisure at home and elsewhere. Time- and frequency-domain HRV indices were calculated and stratified by period and activity type (lying/sitting, standing, or walking. ANCOVAs with multiple adjustments were used to disclose possible group differences in HRV. Results. The pain group showed a reduced HRV response to physical activity compared with controls (p=.001, according to the sympathetic-baroreceptor HRV index (LF/HF, ratio between low- and high-frequency power, even after adjustment for leisure time physical activity, work stress, sleep quality, mental health, and aerobic capacity (p=.02. The parasympathetic response to physical activity did not differ between groups. Conclusions. Relying on long-term monitoring of physical behavior and heart rate variability, we found an aberrant sympathetic-baroreceptor response to daily physical activity among subjects with chronic neck pain.
