Learning, Teaching and Implementing: What is Sustainability?

NASA Astrophysics Data System (ADS)

Fausnaugh, Carolyn J.

2009-07-01

This essay describes the author's personal journey to an increasing awareness of the need for incorporating "sustainability thinking" in university curricula across disciplines. Awareness without action is hollow. The essay describes the process by which sustainability thinking is incorporated into the experience of every student graduating from the Florida Tech College of Business.

Nuclear Physicists in Finance

Mattoni, Carlo

2017-01-01

The financial services industry presents an interesting alternative career path for nuclear physicists. Careers in finance typically offer intellectual challenge, a fast pace, high caliber colleagues, merit-based compensation with substantial upside, and an opportunity to deploy skills learned as a physicist. Physicists are employed at a wide range of financial institutions on both the ``buy side'' (hedge fund managers, private equity managers, mutual fund managers, etc.) and the ``sell side'' (investment banks and brokerages). Historically, physicists in finance were primarily ``quants'' tasked with applying stochastic calculus to determine the price of financial derivatives. With the maturation of the field of derivative pricing, physicists in finance today find work in a variety of roles ranging from quantification and management of risk to investment analysis to development of sophisticated software used to price, trade, and risk manage securities. Only a small subset of today's finance careers for physicists require the use of advanced math and practically none provide an opportunity to tinker with an apparatus, yet most nevertheless draw on important skills honed during the training of a nuclear physicist. Intellectually rigorous critical thinking, sophisticated problem solving, an attention to minute detail and an ability to create and test hypotheses based on incomplete information are key to both disciplines.

The Mental Aftermath - The Mentality of German Physicists 1945-1949

NASA Astrophysics Data System (ADS)

Hentschel, Klaus

2007-01-01

Few scientific communities have been more thoroughly studied than 20th-century German physicists. Yet their behavior and patterns of thinking immediately after the war remains puzzling. During the first five postwar years they suspended their internecine battles and a strange solidarity emerged. Former enemies were suddenly willing to exonerate each other blindly and even morally upright physicists began to write tirades against the 'denazification mischief' or the 'export of scientists'. Personal idiosyncracies melded into a strangely uniform pattern of rejection or resistance to the Allied occupiers, with attendant repressed feelings and self-pity. Politics was once again perceived as remote, dirty business. It was feared that the least concession of guilt would bring down even more severe sanctions on their discipline. Using tools from the history of mentality, such as analysis of serial publications, these tendenciesare examined. The perspective of emigre physicists, as reflected in their private letters and reports, embellish this portrait.

A Gendered Approach to Science Ethics for US and UK Physicists.

PubMed

Ecklund, Elaine Howard; Di, Di

2017-02-01

Some research indicates that women professionals-when compared to men-may be more ethical in the workplace. Existing literature that discusses gender and ethics is confined to the for-profit business sector and primarily to a US context. In particular, there is little attention paid to gender and ethics in science professions in a global context. This represents a significant gap, as science is a rapidly growing and global professional sector, as well as one with ethically ambiguous areas. Adopting an international comparative perspective, this paper relies on 121 semi-structured interviews with US and UK academic physicists to examine how physicists perceive the impact of gender on science ethics. Findings indicate that some US and UK physicists believe that female scientists handle ethical issues within science in a feminine way whereas their male colleagues approach ethics in a masculine way. Some of these physicists further claim that these different approaches to science ethics lead to male and female scientists' different levels of competitiveness in academic physics. In both the US and the UK, there are "gender-blind" physicists, who do not think gender is related to professional ethics. Relying on physicists' nuanced descriptions this paper contributes to the current understanding of gender and science and engineering ethics.

Urgency of evolution-process congruent thinking in physics

NASA Astrophysics Data System (ADS)

Roychoudhuri, Chandrasekhar

2015-09-01

It is now generally recognized that physics has not been contributing anything conceptually fundamentally new beyond the century old Relativity and 90 years old Quantum Mechanics [1-4]. We have also started recognizing that there is an increasing rate of species extinction all over the world, especially since the last century [5]; and we are beginning to understand that the related problems are being steadily accelerated by human behavior to conquer nature, rather than understanding nature as is and living within its system logics [6,7]. We are beginning to appreciate that our long-term sustainability as a species literally depends upon proactively learning to nurture the entire bio-diversity [8-10]. Thus, humans must consciously become evolution process congruent thinkers. The evolutionary biologists have been crying out loud for us to listen [5,6, 8-10]. Social scientists, political scientists, economic scientists [13] have started chiming in to become consilient thinkers [6] for re-constructing sustainable societies. But, the path to consilient thinking requires us to recognize and accept a common vision based thinking process, which functionally serves as a uniting platform. I am articulating that platform as the "evolution process congruent thinking" (EPCT). Do physicists have any obligation to co-opt this EPCT? Is there any immediate and/or long-term gain for them? This paper argues affirmatively that co-opting EPCT is the best way to re-anchor physics back to reality ontology and develop newer and deeper understanding of natural phenomena based on understanding of the diverse interaction processes going on in nature. Physics is mature enough to acknowledge that all of our theories are "work in progress". This is a good time to start iteratively re-evaluating and re-structuring all the foundational postulates behind all the working theories. This will also consistently energize all the follow-on generation of physicists to keep on fully utilizing their evolution-given enquiring minds without being afraid by the prevailing culture of "publish-or-perish", requiring them to stay within the bounds of the prevailing theories as the final ones. Current physics thinking has been successfully driven by Measurable Data Modeling Epistemology (MDM-E); which is basically curve-fitting without demanding to understand the actual physical processes nature is carrying out. I am proposing to add an iterative repertoire, Interaction Process mapping Epistemology (IPM-E) over and above successful MDM-E. This will facilitate the physicists to become conceptual reverse engineers of nature. The gap between physicists and engineers will start melting down and our collective sustainability will be re-assured as successful engineers of nature.

Documenting and Interpreting Ways to Engage Students in `Thinking Like a Physicist'

NASA Astrophysics Data System (ADS)

van Zee, Emily; Manogue, Corinne

2010-10-01

The Paradigms in Physics Program at Oregon State University has adapted a variety of interactive pedagogies to engage students in `thinking like a physicist.' Video recordings of class sessions document what the students and instructor say and do. This paper discusses development of narrative interpretations of such videos. Examples are drawn from two detailed narratives of activities during which the main ideas emerged during the wrap-up discussions rather than during the tasks that the students had been doing in their small groups. The goal of these `compare and contrast' wrap-up discussions was to help the students envision connections among geometric and algebraic representations of the mathematics they would be using during the coming weeks of instruction in quantum mechanics. The purpose of the narratives is to provide examples of wrap-up discussions with commentary about ways in which the instructor was choosing to guide this process.

Leo Szilard Lectureship Award Talk: From Reductionism to Complexity; A Theoretical Physicist's Journey into Biology and the Social Sciences

NASA Astrophysics Data System (ADS)

West, Geoffrey

2013-04-01

In this talk I review how a high energy physicist serendipitously migrated from quarks and gluons, dark matter and string theory to thinking about equally big topics like why we live for 100 years (and not a thousand or 2-3 like a mouse), how is this generated from molecular time scales, why do we sleep and where does 8 hours come from, and how is this related to the rate at which we evolve, can there be a quantitative, mathematisable science of cities and companies, and can our exponentially expanding socio-economic universe be sustained, etc, etc? I consider these as integral parts of physics, related to the interface between Reductionism and Complexity, Thermodynamics and Information Theory. The saga will be a personal one ranging from issues connected with the demise of the SSC and attacks on science to the future role of physics and transdisciplinary thinking.

Implementing NICU critical thinking programs: one unit's experience.

PubMed

Zimmerman, Denise; Pilcher, Jobeth

2008-01-01

Critical thinking is the hallmark of today's nursing practice environment. Nowhere is this more critical than in the high-tech environment of the NICU. Despite the importance of critical thinking in nursing practice, there is limited information on the process of teaching new NICU nurses to think critically. Based on the principles of adult education, orientation and continuing education for NICU nurses should be goal directed, build on the learner's prior experience, and build in opportunities for active participation, reflection, and experiential learning. This article reviews the principles of adult education and their application to the process of teaching critical thinking in the NICU. One unit's experience of critical thinking education is used to provide concrete examples of how NICU education can be transformed from a traditional didactic methodology to a more dynamic experiential approach.

Information as a Measure of Model Skill

NASA Astrophysics Data System (ADS)

Roulston, M. S.; Smith, L. A.

2002-12-01

Physicist Paul Davies has suggested that rather than the quest for laws that approximate ever more closely to "truth", science should be regarded as the quest for compressibility. The goodness of a model can be judged by the degree to which it allows us to compress data describing the real world. The "logarithmic scoring rule" is a method for evaluating probabilistic predictions of reality that turns this philosophical position into a practical means of model evaluation. This scoring rule measures the information deficit or "ignorance" of someone in possession of the prediction. A more applied viewpoint is that the goodness of a model is determined by its value to a user who must make decisions based upon its predictions. Any form of decision making under uncertainty can be reduced to a gambling scenario. Kelly showed that the value of a probabilistic prediction to a gambler pursuing the maximum return on their bets depends on their "ignorance", as determined from the logarithmic scoring rule, thus demonstrating a one-to-one correspondence between data compression and gambling returns. Thus information theory provides a way to think about model evaluation, that is both philosophically satisfying and practically oriented. P.C.W.

Darwin's legacy

NASA Astrophysics Data System (ADS)

Susskind, Leonard

2009-07-01

Charles Darwin was no theoretical physicist, and I am no biologist. Yet, as a theoretical physicist, I have found much to think about in Darwin's legacy - and in that of his fellow naturalist Alfred Russell Wallace. Darwin's style of science is not usually thought of as theoretical and certainly not mathematical: he was a careful observer of nature, kept copious notes, contributed to zoological collections; and eventually from his vast repertoire of observation deduced the idea of natural selection as the origin of species. The value of theorizing is often dismissed in the biological sciences as less important than observation; and Darwin was the master observer.

A theoretical physicist's journey into biology: from quarks and strings to cells and whales.

PubMed

West, Geoffrey B

2014-10-08

Biology will almost certainly be the predominant science of the twenty-first century but, for it to become successfully so, it will need to embrace some of the quantitative, analytic, predictive culture that has made physics so successful. This includes the search for underlying principles, systemic thinking at all scales, the development of coarse-grained models, and closer ongoing collaboration between theorists and experimentalists. This article presents a personal, slightly provocative, perspective of a theoretical physicist working in close collaboration with biologists at the interface between the physical and biological sciences.

Reaching Out: The Bachelor of Arts Degree In Physics

NASA Astrophysics Data System (ADS)

Hobson, Art

1996-05-01

Physics degrees are not only for physicists. Our department believes that it would be healthy if attorneys, physicians, journalists, politicians, businesspeople, and others had undergraduate degrees in physics. Thus, we have begun offering a Bachelor of Arts degree in physics, for students who want to study physics as a background for other fields such as law (patents, environmental law), medical school, business (high-tech firms), journalism (science reporting, environmental reporting), music (accoustics, electronic music), and essentially any other profession. The program reaches outward, outside of physics, rather than pointing toward further work in physics. It begins with the algebra-based introductory course rather than the calculus-based course for future physicists and engineers. Two new courses are being created to provide these pre-professional students with broad science literacy and knowledge of physics-related technologies. The program is more flexible and less technical than the traditional Bachelor of Science program, allowing students time for outside electives and professional requirements in other fields.

It is hard to think of a medium that does not use football or soccer as a means of promotion. It is also hard to think of a student who has not heard of David Beckham. If football captures the interest of students it can be used to teach physics; in this case a Beckham free-kick can be used to introduce concepts such as drag, the Bernoulli principle, Reynolds number and the Magnus effect, by asking the simple question: How does he curve the ball so much? Much basic mechanics can also be introduced along the way.

Virtual reality helmet display quality influences the magnitude of virtual reality analgesia.

Immersive Virtual Reality (VR) distraction can be used in addition to traditional opioids to reduce procedural pain. The current study explored whether a High-Tech-VR helmet (ie, a 60-degree field-of-view head-mounted display) reduces pain more effectively than a Low-Tech-VR helmet (a 35-degree field-of-view head-mounted display). Using a double-blind between-groups design, 77 healthy volunteers (no patients) aged 18-23 were randomly assigned to 1 of 3 groups. Each subject received a brief baseline thermal pain stimulus, and the same stimulus again minutes later while in SnowWorld using a Low-Tech-VR helmet (Group 1), using a High-Tech-VR helmet (Group 2), or receiving no distraction (Group 3, control group). Each participant provided subjective 0-10 ratings of cognitive, sensory, and affective components of pain, and amount of fun during the pain stimulus. Compared to the Low-Tech-VR helmet group, subjects in the High-Tech-VR helmet group reported 34% more reduction in worst pain (P < .05), 46% more reduction in pain unpleasantness (P = .001), 29% more reduction in "time spent thinking about pain" (P < .05), and 32% more fun during the pain stimulus in VR (P < .05). Only 29% of participants in the Low-Tech helmet group, as opposed to 65% of participants in the High-Tech-VR helmet group, showed a clinically significant reduction in pain intensity during virtual reality. These results highlight the importance of using an appropriately designed VR helmet to achieve effective VR analgesia (see ). Pain during medical procedures (eg, burn wound care) is often excessive. Adjunctive virtual reality distraction can substantially reduce procedural pain. The results of the present study show that a higher quality VR helmet was more effective at reducing pain than a lower quality VR helmet.

Obituary: Albert G. Petschek, 1928-2004

NASA Astrophysics Data System (ADS)

Colgate, Stirling A.; Petschek, Rolfe G.; Libersky, Larry D.

2005-12-01

Albert G. Petschek died suddenly 8 July 2004. He enjoyed good health and was very active professionally and personally until his death. He was highly respected, particularly in theoretical physics, for his deep, broad-ranging analytical powers, which resulted in contributions to nuclear physics, astrophysics, atmospheric physics, quantum mechanics, and quantum computing. Albert was born in Prague, Czechoslovakia in 1928. His extended family left Czechoslovakia when its sovereignty was threatened by Germany in 1938 and settled throughout the Western Hemisphere. Albert's father, a banker, settled in Scarsdale, near New York City. Albert graduated from White Plains High School and obtained his BS from MIT in a program accelerated during World War II. While getting his masters degree at the University of Michigan, Albert met his wife, Marilyn, also a physics masters student. In 1953, Albert obtained his PhD from the University of Rochester working with Robert Marshak on aspects of nuclear theory, and joined Los Alamos National Laboratory (LANL), then Los Alamos Scientific Laboratory. Soon thereafter, Albert's younger brother, Harry, also became a PhD physicist. Harry is now well known in plasma physics for reconnection theory. At Los Alamos, Albert worked closely with Carson Mark, Marshall Rosenbluth, and Conrad Longmire designing the first thermonuclear weapons. His derivation of several radiation diffusion solutions, later published as LAMS 2421, remains a classic in its field, as does work on nuclear theory done with Baird Brandow and Hans Bethe during a sabbatical at Cornell in 1961. Bethe was a frequent visitor to Los Alamos and a close friend. A devoted family man, Albert also valued Los Alamos as a safe, stimulating environment for raising an active family. Like many of the scientists at Los Alamos, Albert enjoyed its ready access to outdoor activities such as hiking and skiing. Albert often combined his passions for intellectual activity and the outdoors - discussing Lie groups around a camp fire or the controversies concerning the origin of lightning in electrical storms while hiking through a high mountain pass, watching a thundercloud form. Albert's son Rolfe was inspired in part by such outings to become a professional physicist. For more than a decade following his PhD, Albert's primary scientific work was secret, contributing to the security of his adopted country, and he published little in the open literature. However, by the time of his death, Albert's broad interests and scientific rigor had resulted in 69 cited papers on such diverse topics as nuclear theory, plasma physics, radiation, numerical hydrodynamics and plastic flow, astrophysics (supernovae, quasars, gamma-ray bursts), chemical kinetics, atmospheric physics (plumes, electrification), geotectonics, nuclear weapons effects, inertial fusion and quantum computing. Even this list understates Albert's intellectual breadth: while his scientific publications are all in physics, he was also very knowledgeable in some aspects of biology and finance, and his broad-ranging analytical powers were appreciated by practitioners of many professions. In an increasingly specialized world, Albert's broad interests, wide knowledge, and willingness to think deeply about many problems are inspiring. In 1966 Albert joined the faculty of New Mexico Institute of Mining and Technology (New Mexico Tech) in Socorro, New Mexico, as a full professor. In 1968 he left Tech to spend three years at Science, Systems and Software, a scientific consulting firm in San Diego California, and then returned to New Mexico Tech. Albert's intellectual leadership, the courses he taught in theoretical physics, and his frequent, insightful questions at seminars will long be remembered by those with whom he interacted at New Mexico Tech. Of his 69 published works, 39 were published in collaboration with Stirling Colgate. Colgate, at that time New Mexico Tech's president, had helped recruit Albert there. Albert's PhD students at New Mexico Tech keenly remember his patience, kindness and availability. His office door was always open, and he was eager to lead them through difficulties in their research. Albert maintained his connection to LANL while at New Mexico Tech, consulting at LANL during many holidays and summers. In 1981 he became one of the first Fellows of Los Alamos National Laboratories. Albert also enjoyed service to the science community, editing a book on supernovae (1990), routinely judging local and regional science fairs, and advising LANL on the recipients of the Los Alamos prize. In 1987, Albert retired from New Mexico Tech and returned full time to Los Alamos in the Physics division. Although he subsequently retired from LANL in 1994, he remained very active at LANL until his death, spending three to four days there most weeks as an emeritus fellow, consultant, and frequent attendee of, and questioner at, seminars and colloquia. During this period his published scientific contributions were primarily to quantum computing and numerical hydrodynamics. While he was retired Albert's part time status allowed him to spend yet more time with his family and he explored many parts of the world with them. Albert was an avid hiker, cross country skier, mushroom gatherer, gardener, and bicyclist. He commuted by bicycle between his home in La Senda and the Lab, an elevation change of 200 meters, in almost any weather, until his death. He is survived by Marilyn, his wife of 55 years, his brother Harry, his four children, Evelyn, Rolfe, Elaine, and Mark and three grandchildren.

From third Health Physics Society midyear topical symposium; Los Angeles, California, USA (29 Jan 1969). See CONF-690103P3. The health physicist, if he is to be effective in his profession, needs to develop his communication capabilities with craftsmen, management, and the public. His communications should meet the needs of and be understood by those receiving them. Second only to a thorough knowledge of the principles of health physics, persuasion is the health physicist' s biggest and best tool. By effective persuasion the health physicist should be able to accomplish his necessary work but he should always be ready to insist andmore » to stand firm to assure a safe course of action should his persuasive efforts prove to be ineffective. Public communications in the health physics field should be frequent. The organizational location of a health physics program in a corporate structure is optional. Good people will lead to a good program. In most situations an organizational position high in the corporate structure will help to assure proper importance and emphasis to the health physics program. In all cases clear lines of authority should be established and mutually understood by the health physicist, the craftsmen, and management. (auth)« less

Dad's in the Garage: Santa Barbara Physicists in the Long 1970s

NASA Astrophysics Data System (ADS)

Mody, Cyrus

2013-03-01

American physicists faced many challenges in the 1970s: declining research budgets; public skepticism of scientific authority; declining student enrollments; and pressure to shift to topics such as biomedicine, environmental remediation, alternative energy, public housing and transport, and disability technologies. This paper examines the responses to these challenges of a small group of Santa Barbara physicists. While this group is not representative of the American physics profession, the success and failure of their responses to changed conditions tells us something about how American physicists got through the 1970s, and about the origins of some features of American physics today. The three physicists examined here are Philip Wyatt, David Phillips, and Virgil Elings. In the late `60s, Wyatt left a defense think tank to found an instrumentation firm. The Santa Barbara oil spill and other factors pushed that firm toward civilian markets in biomedicine and pollution measurement. Phillips joined Wyatt's firm from UCSB, while also founding his own company, largely to sell electronic devices for parapsychology. Phillips was also the junior partner in a master's of scientific instrumentation degree curriculum founded by Elings in order to save UCSB Physics' graduate program. Through the MSI program, Elings moved into biomedical research and became a serial entrepreneur. By the 1990s, Wyatt, Phillips, and Elings' turn toward academic entrepreneurship, dual military-civilian markets for physics start-ups, and interdisciplinary collaborations between physicists and life scientists were no longer unusual. Together, their journey through the `70s shows how varied the physics' profession's response to crisis was, and how much it pivoted on new interactions between university and industry.

Critical Thinking and Disposition Toward Critical Thinking Among Physical Therapy Students.

Domenech, Manuel A; Watkins, Phillip

2015-01-01

Students who enter a physical therapist (PT) entry-level program with weak critical thinking skills may not be prepared to benefit from the educational training program or successfully engage in the future as a competent healthcare provider. Therefore, assessing PT students' entry-level critical thinking skills and/or disposition toward critical thinking may be beneficial to identifying students with poor, fair, or good critical thinking ability as one of the criteria used in the admissions process into a professional program. First-year students (n=71) from the Doctor of Physical Therapy (DPT) program at Texas Tech University Health Sciences Center completed the California Critical Thinking Skills Test (CCTST), the California Critical Thinking Dispositions Inventory (CCTDI), and demographic survey during orientation to the DPT program. Three students were lost from the CCTST (n=68), and none lost from the CCTDI (n=71). Analysis indicated that the majority of students had a positive disposition toward critical thinking, yet the overall CCTST suggested that these students were somewhat below the national average. Also, individuals taking math and science prerequisites at the community-college level tended to have lower overall CCTST scores. The entering DPT class demonstrated moderate or middle range scores in critical thinking and disposition toward critical thinking. This result does not indicate, but might suggest, the potential for learning challenges. Assessing critical thinking skills as part of the admissions process may prove advantageous.

Abusive Supervision and Job Dissatisfaction: The Moderating Effects of Feedback Avoidance and Critical Thinking

PubMed Central

2017-01-01

Although research on the antecedents of job dissatisfaction has been developed greatly, we know little about the role of abusive supervision in generating job dissatisfaction. The contingencies under which abusive supervision relates to employees’ job dissatisfaction are still unknown. The present study aimed to fill this research gap by empirically exploring the abusive supervision-job dissatisfaction relationship as well as examining the moderating roles of feedback avoidance and critical thinking on this relationship. We tested the hypotheses with data from a sample of 248 employees from a high-tech communications company in northern China and found that: (a) abusive supervision was positively related to job dissatisfaction; (b) the positive relationship was moderated by both employees’ feedback avoidance and critical thinking. We conclude by extracting the theoretical as well as practical contributions, along with a discussion of the promising directions for future research. PMID:28408899

Biophysics at the Boundaries: The Next Problem Sets

NASA Astrophysics Data System (ADS)

Skolnick, Malcolm

2009-03-01

The interface between physics and biology is one of the fastest growing subfields of physics. As knowledge of such topics as cellular processes and complex ecological systems advances, researchers have found that progress in understanding these and other systems requires application of more quantitative approaches. Today, there is a growing demand for quantitative and computational skills in biological research and the commercialization of that research. The fragmented teaching of science in our universities still leaves biology outside the quantitative and mathematical culture that is the foundation of physics. This is particularly inopportune at a time when the needs for quantitative thinking about biological systems are exploding. More physicists should be encouraged to become active in research and development in the growing application fields of biophysics including molecular genetics, biomedical imaging, tissue generation and regeneration, drug development, prosthetics, neural and brain function, kinetics of nonequilibrium open biological systems, metabolic networks, biological transport processes, large-scale biochemical networks and stochastic processes in biochemical systems to name a few. In addition to moving into basic research in these areas, there is increasing opportunity for physicists in industry beginning with entrepreneurial roles in taking research results out of the laboratory and in the industries who perfect and market the inventions and developments that physicists produce. In this talk we will identify and discuss emerging opportunities for physicists in biophysical and biotechnological pursuits ranging from basic research through development of applications and commercialization of results. This will include discussion of the roles of physicists in non-traditional areas apart from academia such as patent law, financial analysis and regulatory science and the problem sets assigned in education and training that will enable future biophysicists to fill these roles.

A Deliberate Practice Instructional Approach for Upper Division Physics Courses

NASA Astrophysics Data System (ADS)

Jones, David

2015-05-01

In upper division physics courses, an overarching educational goal is to have students think about and use the material much as a practicing physicist in the field does. Specifically, this would include knowledge (such as concepts, formalism, and instruments), approaches, and metacognitive skills that physicists use in solving ``typical'' (research context) problems to both understand and predict physical observations and accompanying models. Using an interactive instructional approach known as deliberate practice (described earlier in this session) we will discuss our work on how to provide students with the necessary practice and feedback to achieve these skills in a core DAMOP course of modern optics. We present the results of a direct and explicit comparison between this approach and traditional lecture-based instruction revealing evidence that a significant improvement of the students' mastery of these skills occurs when deliberate practice is employed. Our work was supported by the University of British Columbia through the CWSEI.

Social norms of "good" design: Interdisciplinary perspectives from a survey of engineers and clinicians in bioengineering.

PubMed

Johnson, Angela N

2016-08-01

In bioengineering training for new researchers and engineers, a great deal of time is spent discussing what constitutes "good" design. Conceptualization of good design, however, varies widely across interdisciplinary team members, with potential to both foster innovation or lead to unproductive conflict. To explore how groups central to bioengineering teams (physicians/clinicians and engineers/physicists) conceptualize good design, we asked 176 professionals in bioengineering to complete a comprehensive online survey including items designed to assess cognitive and moral foundations (validated MFQ30 tool) and custom items assessing perceptions on good design in three areas (good design characteristics, reputation of design approvers, and perceived design patient/consumer suitability). Of those that responded, 82 completed all quantitative survey sections and were included in this preliminary analysis. Correlations between response areas were examined to explore the possible links between cognitive and moral biases and perspectives on good design. The survey results indicated that both groups were more conservative than average Americans based on previous reports, and clinicians scored higher on average for all MFQ30 domains. Numerous significant correlations with good design were observed among clinicians, while engineers/physicists most closely correlated good design with prescriber approval and scientific/technical literature. The exploratory analysis demonstrated the potential utility of sociological frameworks to explore relationships in design thinking with potential utility to stimulate thriving conversation on team-based design thinking in bioengineering education and practice.

Money and sentiment: a psychodynamic approach to behavioral finance.

PubMed

Mohacsy, Ildiko; Lefer, Heidi

2007-01-01

This article tackles one of the timeliest issues for both practitioners and patients today: sentiment, psychodynamics, and the stock market. Economic bubbles and crashes have occurred regularly through history -- from Holland's 17th century tulip mania, to America's 19th century railway mania, to the 1990s high-tech obsession. Though most investors regard themselves as investing rationally, few do. Instead they react collectively, buying high and selling low in crowds. Being subject to the illusion of control, they follow regressive behavior patterns and irrational, wishful thinking. They are victimized by their own emotions of hope, fear, and uncertainty. Crises happen often in economics. Indeed, the market itself may be quantified as a conglomeration of human sentiment. The relationship between magical thinking and the pictorial language of the market will be explored. Psychodynamic conceptualizations about risk and speculation are discussed, as are the interplay of affects versus judgment, rational thinking, and the knowledge of one's own capacity for stress tolerance.

China and India: A New Sputnik? Federal Funding of Physical Sciences Research

Federal funding for the physical sciences has been stagnant for many decades, hindering scientific progress in many regards. Meanwhile, in the last decade, countries like China and India have made huge strides in improving their science and technology infrastructure, to the extent that U.S. leadership in many scientific fields is, or will soon be, challenged. The United States is also losing high-tech market share and jobs. Just as Sputnik jolted the U.S. into action 50 years ago, many believe that the current challenges require a Sputnik-like response. The American Physical Society is working hard to convince Members of Congress and the Administration to increase science research funding. In this talk, I will discuss challenges to U.S. science leadership and the APS advocacy. I will also address whether physicists can have an impact in Washington.

2011-02-01

Improving treatment outcomes for people with resonance problems (due to velopharyngeal disorders) is a priority for many speech-language pathologists (SLPs), but there exists a limited understanding of the practices SLPs are using to assess and monitor therapeutic effects in this population. The current study was designed to answer the following questions: (1) What are current clinical practices versus best practices for assessing resonance disorders, tracking therapeutic effects, and determining discharge criteria? (2) What assessment practices would SLPs prefer to use with clients who have resonance disorders? (3) What are barriers to SLPs' use of best practices? and (4) What effects do SLP demographics have on clinical practices? Thirty-eight SLPs, specializing in the treatment of resonance disorders, participated in the study. Responses were compared with best practice recommendations derived from the literature. Most clinicians were using low-tech assessment tools, often because they lacked access to high-tech tools. Demographics and training did not affect clinical assessment practices. There is a need to increase the availability of high-tech assessment tools to SLPs practicing in the area of resonance disorders, as consistent use of sophisticated assessment devices would exemplify contemporary thinking about the transfer of knowledge to practice in this area. © Thieme Medical Publishers.

What are you thinking about? There is a crisis in recruiting physics teachers throughout Northern Europe. Detailed research has shown that the problem may be one of image. It seems that being a teacher is seen as something slightly strange. So is being a physicist. This makes anyone who is a physics teacher (strange)2. This effect becomes overwhelming when more than one physics teacher is present, making attendance at gatherings of physics teachers almost unthinkable for the average person. So just what is it that sets physicists aside from the rest of the population? Why do they think we are so strange? Clearly it is how we think about things. We enter a room and estimate its volume. We visit the fairground and we wonder about the g force. At a football match we estimate the size of the crowd. At sunset we see scattering and at the beach, as the sun glints off the clear water, we think about Brewster's angle, and we estimate the number of pebbles on the beach. We find potential visits and lesson-material at hospitals, concerts, restaurants and on every possible mode of transport. Thinking about things like that is what makes us physics teachers. Surely everyone has seen The Wizard of Oz. I want you to imagine that you are watching it along with some friends who are not physics teachers. Let's see what they are all thinking about. One is a Roads Engineer. What a state the yellow brick road is in! As the major route in the country of Oz it obviously needs an upgrade. A nice black tarmac surface, some road markings and lighting at the major intersections. There is something else wrong. Dorothy, the Tin man, Scarecrow and Lion are just walking along. Where are the road works, traffic jams and hold-ups? Another friend is a school principal. What an amazing leadership style the Wizard has. Perhaps it would work at school? Those munchkins run around a bit though. There would be a need for some rules about how to play in the playground. Perhaps if the mayor of the Munchkins were to be on performance related pay things might improve? And what are you thinking? What is the conductance of the Tin man? Would it vary measured from head to toe or hand to hand? Students could do extended investigations into the conductance of different body parts. There are surely some great opportunities for projects and science fairs. Students could investigate the suitability of different materials for making Tin man suits. They could do a special display... So you are thinking again, but so are they. Everyone sees the world from their own perspective. Perhaps people think the perspective of a physics teacher is a bit strange. We must stand up for ourselves and fight back. It is time to tell the world what good people we are to know - far more interesting than road engineers or school principals. After all, look at what they think about when they watch The Wizard of Oz! If this positive image projection fails to recruit more physics teachers I can propose an alternative. There are about as many giant pandas in the world as physics teachers in the UK. There is a breeding programme for pandas. Now there's an idea ... . What good people we are to know - far more interesting than road engineers or school principals. After all, look at what they think about when they watch The Wizard of Oz!

Dual-Readout Calorimetry for High-Quality Energy Measurements. Final Report

2013-09-01

This document constitutes the final report on the project Dual-Readout Calorimetry for High-Quality Energy Measurements. The project was carried out by a consortium of US and Italian physicists, led by Dr. Richard Wigmans (Texas tech University). This consortium built several particle detectors and tested these at the European Center for Nuclear Research (CERN) in Geneva, Switzerland. The idea arose to use scintillating crystals as dual-readout calorimeters. Such crystals were of course already known to provide excellent energy resolution for the detection of particles developing electromagnetic (em) showers. The efforts to separate the signals from scintillating crystals into scintillation and Cerenkovmore » components led to four different methods by which this could be accomplished. These methods are based on a) the directionality, b) spectral differences, c) the time structure, and d) the polarization of the signals.« less

Uncertainty and Surprise: Ideas from the Open Discussion

NASA Astrophysics Data System (ADS)

Jordan, Michelle E.

Approximately one hundred participants met for three days at a conference entitled "Uncertainty and Surprise: Questions on Working with the Unexpected and Unknowable." There were a diversity of conference participants ranging from researchers in the natural sciences and researchers in the social sciences (business professors, physicists, ethnographers, nursing school deans) to practitioners and executives in public policy and management (business owners, health care managers, high tech executives), all of whom had varying levels of experience and expertise in dealing with uncertainty and surprise. One group held the traditional, statistical view that uncertainty comes from variance and events that are described by usually unimodal probability law. A second group was comfortable on the one hand with phase diagrams and the phase transitions that come from systems with multi-modal distributions, and on the other hand, with deterministic chaos. A third group was comfortable with the emergent events from evolutionary processes that may not have any probability laws at all.

Intertwining evidence- and model-based reasoning in physics sensemaking: An example from electrostatics

NASA Astrophysics Data System (ADS)

Russ, Rosemary S.; Odden, Tor Ole B.

2017-12-01

Our field has long valued the goal of teaching students not just the facts of physics, but also the thinking and reasoning skills of professional physicists. The complexity inherent in scientific reasoning demands that we think carefully about how we conceptualize for ourselves, enact in our classes, and encourage in our students the relationship between the multifaceted practices of professional science. The current study draws on existing research in the philosophy of science and psychology to advocate for intertwining two important aspects of scientific reasoning: using evidence from experimentation and modeling. We present a case from an undergraduate physics course to illustrate how these aspects can be intertwined productively and describe specific ways in which these aspects of reasoning can mutually reinforce one another in student learning. We end by discussing implications for this work for instruction in introductory physics courses and for research on scientific reasoning at the undergraduate level.

Christmas in Physics Land

NASA Astrophysics Data System (ADS)

1999-01-01

A short story of everyday folk for the Yuletide season It was a beautiful scene. Children were sledging, or at least adults were sledging whilst the children waited for a go. Snow flakes were falling gently to the ground. The physicist was extremely content. All the snow flakes had a perfectly symmetric hexagonal crystal structure; the sledges were all reaching the bottom of the slope at just the correct velocity, neglecting heat loss due to friction. A skater went past. The physicist smiled. The change in melting point under the blades was just as it should have been, and angular momentum was completely conserved in the pirouette. A snowball hit the physicist squarely in the face, probably thrown by a geographer. But even this made the physicist laugh, as the trajectory was perfect, as long as you accounted for the changing mass. How different to last year when the physicist had spent Christmas in the real world. How glad he was that he had come to Physics Land for the festive season where everything was just as it ought to be. Someone in the crowd barged into him, but it didn't matter, he was a boson, so they just ignored each other. How horrid it had been last Christmas.... As a young man carrying a light ladder went past, whistling merrily and enjoying the experience of the Doppler effect, the physicist leant back against the perfectly smooth wall, revelling in the joy of resolving his forces on the rough ground... and began to think dark thoughts about the previous year. You see the problem with the real world was that it didn't understand physicists at all. Probably the worst place of all for a physicist was at a party. So often things would go wrong and he would leave early in disgrace. How well he remembered the evening when he had been curious whether it was a pnp or npn type semiconductor controlling the disco lights. It had taken barely three hours to reassemble the lights, and indeed improve on the flashing sequence by altering the reverse bias voltage, but no-one thanked him. Oh no, they were all just annoyed that he had dismantled the lights at all. That was the real world for you. Conversation had been difficult. People kept asking questions, but then didn't appear to be interested in the answer. One host had commented on the weather and then very rudely drifted off to another guest just as the physicist was making a clear distinction between rotating and inertial reference frames as the fundamental cause of the geostrophic wind. Another guest had made an equally bad impression by being clearly uninterested in a small digression on energy balance which seemed the obvious response to his comment about how warm the room had become as people began to dance. The physicist came out of his day dream. An old man was walking a dog on the end of a light inextensible string. A young girl on a swing was executing simple harmonic motion using a small-angle approximation in the park. Two older boys were investigating moments on a see-saw. A boisterous teenager was having a great time with the centripetal force on a roundabout. Yes, this was the life. In Physics Land, it would be a very merry Christmas. Philip Britton

This book retraces the life of the physicist Wolfgang Pauli, analyses his scientific work, and describes the evolution of his thinking. Pauli spent 30 years as a professor at the Federal Institute of Technology ETH in Zurich, which occupy a central place in this biography. It would be incomplete, however, without a rendering of Pauli's sarcastic wit and, most importantly, of the world of his dreams. It is through the latter that quite a different aspect of Pauli's life comes in, namely his association with the psychology of C.G. Jung and his school.

Environmental evaluation of municipal waste prevention

Highlights: > Influence of prevention on waste management systems, excluding avoided production, is relatively minor. > Influence of prevention on overall supply chain, including avoided production is very significant. > Higher relative benefits of prevention are observed in waste management systems relying mainly on landfills. - Abstract: Waste prevention has been addressed in the literature in terms of the social and behavioural aspects, but very little quantitative assessment exists of the environmental benefits. Our study evaluates the environmental consequences of waste prevention on waste management systems and on the wider society, using life-cycle thinking. The partial prevention of unsolicited mail,more » beverage packaging and food waste is tested for a 'High-tech' waste management system relying on high energy and material recovery and for a 'Low-tech' waste management system with less recycling and relying on landfilling. Prevention of 13% of the waste mass entering the waste management system generates a reduction of loads and savings in the waste management system for the different impacts categories; 45% net reduction for nutrient enrichment and 12% reduction for global warming potential. When expanding our system and including avoided production incurred by the prevention measures, large savings are observed (15-fold improvement for nutrient enrichment and 2-fold for global warming potential). Prevention of food waste has the highest environmental impact saving. Prevention generates relatively higher overall relative benefit for 'Low-tech' systems depending on landfilling. The paper provides clear evidence of the environmental benefits of waste prevention and has specific relevance in climate change mitigation.« less

Couch fort and refrigerator box constructions are staples of early childhood play in American culture. Can this this large-scale fantasy type of play be leveraged to facilitate computational thinking? This thesis looks at the ways Kindergarteners (age 5-6) use two variations of the KIBO robotics platform in their play and learning. The first is the standard KIBO kit developed at the DevTech research group at Tufts University and commercialized by Kinderlab robotics. The second, created by the author, is 100 times bigger and can be ridden by children and adults. Specifically this study addresses the research question "How are children's experiences with big-KIBO different from KIBO?" To do so this thesis presents two analytical tools that were assembled conceptually from literature and the authors experiences with KIBO, examined using the data collected in this study, refined, and used as frameworks for understanding the data. They are a developmental model of programming with KIBO and an operationalization of Bers's (2018) powerful ideas of computational thinking when using KIBO. Vignettes from the data are presented and analyzed using these frameworks. Content and structural play themes are extracted from additional vignettes with each robot. In this study there are no clear differences in the ways children engage in computational thinking or develop their ability to program. There appear to be differences in the ways children play with the robots. Suggesting that a larger robot offers new opportunities and pathways for children to engage in computational thinking tasks. This study makes a case for the importance of thinking developmentally about computational thinking. Connections to literature and theory as well as suggestions for future work, both for children and designers, are discussed.

We present our design and initial implementation of a web service model for running particle-in-cell (PIC) codes remotely from a web browser interface. PIC codes have grown significantly in complexity and now often require parallel execution on multiprocessor computers, which in turn requires sophisticated post-processing and data analysis. A significant amount of time and effort is required for a physicist to develop all the necessary skills, at the expense of actually doing research. Moreover, parameter studies with a computationally intensive code justify the systematic management of results with an efficient way to communicate them among a group of remotely located collaborators. Our initial implementation uses the OOPIC Pro code [1], Linux, Apache, MySQL, Python, and PHP. The Interactive Data Language is used for visualization. [1] D.L. Bruhwiler et al., Phys. Rev.

SpaceTech is a postgraduate program geared primarily for mid-career space professionals seeking to gain or improve their expertise in space systems engineering and in business engineering. SpaceTech provides a lifelong impact on its participants by broadening their capabilities, encouraging systematic "end-to-end" thinking and preparing them for any technical or business-related engineering challenges they may encounter. This flexible 1-year program offers high competency gain and increased business skills. It is held in attractive locations in a flexible, multi-cultural environment. SpaceTech is a highly effective master's program certified by the esteemed Technical University of Delft (TUD), Netherlands. SpaceTech provides expert instructors who place no barriers between themselves and participants. The program combines innovative and flexible new approaches with time-tested methods to give participants the skills required for future missions and new business, while allowing participants to meet their work commitments at the same time as they study for their master's degree. The SpaceTech program is conducted in separate sessions, generally each of 2-week duration, separated by periods of some 6-8 weeks, during which time participants may return to their normal jobs. It also includes introductory online course material that the participants can study at their leisure. The first session is held at the TUD, with subsequent sessions held at strategic space agency locations. By participating at two or more of these sessions, attendees can earn certificates of satisfactory completion from TU Delft. By participating in all of the sessions, as well as taking part in the companion Central Case Project (CCP), participants earn an accredited and highly respected master's degree in Space Systems Engineering from the TUD. Seven distinct SpaceTech modules are provided during these sessions: Space Mission Analysis and Design, Systems Engineering, Business Engineering, Interpersonal Skills, Telecommunications, Earth Observation and Navigation. A group CCP, a major asset of this unique program, is a focused project, aimed at the formation of a credible virtual commercial space-related business. Participants exercise space systems engineering fundamentals as well as marketing and business engineering tools, with the goal of creating a financially viable business opportunity. They then present the result, in the form of an unsolicited proposal to potential investors, as well as a varied group of engineers, managers and executives from the space community. During the CCP, participants learn the ties between mission and system design and the potential return to investors. They develop an instinct for the technical concepts and which of the parameters to adjust to make their newly conceived business more effective and profitable.

A Physicist as President of the University

Dynes, Robert

2005-03-01

My wife, physicist Frances Hellman, is fond of referring to me as a ``restless soul,'' and I do not dispute her. In the 40 years since graduating from the University of Western Ontario with a bachelor's degree in mathematics and physics, I went on to earn master's and doctorate degrees in physics and an honorary doctor of science degree from McMaster University. In 22 years working at AT&T Bell Laboratories, I held five positions, was department head in two departments, and director of one laboratory. At the University of California, San Diego, I was a Professor of Physics, chair of the Department of Physics, senior vice chancellor and then chancellor. Currently, in addition to being a professor of Physics, I am president of the University of California. The ``restless'' trajectory of my career from physics undergraduate to university president follows the nature of physics itself. In physics, you are constantly seeking challenges, experimenting, creating hypotheses, looking for and finding solutions. I recall having a structured view of the world as a boy, a sense that there was a guiding ``master plan'' to most things and that wise, educated, benevolent people were there to implement the plan. ``They'' would do the right thing. Along the way, I realized, ``there is no `they' there; there is only us.'' Acknowledging the laws of thermodynamics-- ``you can't win, you can't break even, and you can't get out of the game'' --I nonetheless believe that if you have a restless mind, an open heart, and intellectual honesty without giving into wishful thinking, physicists can do anything. .

Comparative Cognitive Task Analyses of Experimental Science and Instructional Laboratory Courses

Wieman, Carl

Undergraduate instructional labs in physics generate intense opinions. Their advocates are passionate as to their importance for teaching physics as an experimental activity and providing "hands-on" learning experiences, while their detractors (often but not entirely students) offer harsh criticisms that they are pointless, confusing and unsatisfying, and "cookbook." Here, both to help understand the reason for such discrepant views and to aid in the design of instructional lab courses, I compare the mental tasks or types of thinking ("cognitive task analysis") associated with a physicist doing tabletop experimental research with the cognitive tasks of students in an introductory physics instructional lab involving traditional verification/confirmation exercises.

Your editorial in the July issue (p17) drew attention to the fact that there are many physicists who feel they have a contribution to make, and are fully qualified to do so, but who, for reasons of age, lack of status, lack of good connections or lack of previous publications in the most prestigious journals, are not given an adequate hearing. In the last few decades, physics has become massively institutionalized, and attention is now only given to those people who meet all the "right" criteria of standard career progression, and who stick to the narrow research programmes (such as string theory) outlined by a few influential people.

Historical Examples of Misrepresentation, Innovation, and Morality in Physical Science and Technology

The pressures of publication, the desire to be first in innovation, and moral convictions have long been at work in the history of science and technology. Historians think and argue best through stories, so I've chosen three examples that exemplify one or more of these aspects. The first involves the discovery of electric waves by Heinrich Hertz in 1888; the second concerns the controlled production of electromagnetic radiation by Marconi and Fleming in the early 1900s; our final case involves a bitter controversy between the physicist Hermann von Helmholtz and the astronomer Friedrich Zöllner in the 1890s.

Tragedy of the commons revisited: the high tech-high risk wireless world.

Sage, Cindy

2010-01-01

In 1968, Garrett Hardin, an eminent population ecologist from Santa Barbara, CA published an article in Science titled 'Tragedy of the Commons' that was immediately hailed as a landmark piece of thinking. This paper reshaped prevailing views about our place in the ecological network of the planet and was pivotal in defining how pursuit of our individual actions to maximize self-interest will, across populations all doing the same thing, result in diminished and overused environmental resources. Before sustainability was even a buzzword, Hardin created a way of seeing the world that emphasized how individuals must learn to recognize and to act with more in mind than squeezing one more cow onto the common pasture. He gave us new ways to think about how we might better manage our resources in the face of new technologies. He was not a believer in the technological fix. Those lessons are highly relevant today to the unchecked proliferation of wireless radiofrequency signals, thought by many to cause serious health consequences.

Final Report for "Implimentation and Evaluation of Multigrid Linear Solvers into Extended Magnetohydrodynamic Codes for Petascale Computing"

DOE Office of Scientific and Technical Information (OSTI.GOV)

Srinath Vadlamani; Scott Kruger; Travis Austin

Extended magnetohydrodynamic (MHD) codes are used to model the large, slow-growing instabilities that are projected to limit the performance of International Thermonuclear Experimental Reactor (ITER). The multiscale nature of the extended MHD equations requires an implicit approach. The current linear solvers needed for the implicit algorithm scale poorly because the resultant matrices are so ill-conditioned. A new solver is needed, especially one that scales to the petascale. The most successful scalable parallel processor solvers to date are multigrid solvers. Applying multigrid techniques to a set of equations whose fundamental modes are dispersive waves is a promising solution to CEMM problems.more » For the Phase 1, we implemented multigrid preconditioners from the HYPRE project of the Center for Applied Scientific Computing at LLNL via PETSc of the DOE SciDAC TOPS for the real matrix systems of the extended MHD code NIMROD which is a one of the primary modeling codes of the OFES-funded Center for Extended Magnetohydrodynamic Modeling (CEMM) SciDAC. We implemented the multigrid solvers on the fusion test problem that allows for real matrix systems with success, and in the process learned about the details of NIMROD data structures and the difficulties of inverting NIMROD operators. The further success of this project will allow for efficient usage of future petascale computers at the National Leadership Facilities: Oak Ridge National Laboratory, Argonne National Laboratory, and National Energy Research Scientific Computing Center. The project will be a collaborative effort between computational plasma physicists and applied mathematicians at Tech-X Corporation, applied mathematicians Front Range Scientific Computations, Inc. (who are collaborators on the HYPRE project), and other computational plasma physicists involved with the CEMM project.« less

Solving a problem by using what you know: a physicist looks at a problem in ecology

NASA Astrophysics Data System (ADS)

Greenler, Robert

2015-08-01

Two philosophical ideas motivate this paper. The first is an answer to the question of what is an appropriate activity for a physicist. My answer is that an appropriate activity is anything where the tools of a physicist enable him or her to make a contribution to the solution of a significant problem. This may be obvious in areas that overlap physics (e.g. chemistry, engineering, geology) but also true in any endeavour where mathematical modelling may contribute insight to the solution of problems (e.g. timing of traffic lights, efficient ways to seat passengers on airplanes, whether it is better to walk or run in a rain shower). The second idea concerns an approach to problem solving. Before some people try to solve a problem, they think they first must learn everything that is known about the subject. However, sometimes an effective approach is to declare, ‘I’m going to solve this problem with what I know now!’ I see a relationship between this approach and the idea of back-of-the-envelope calculations, which many of us appreciate. Of course there are limitations to this method, but I believe that such an aggressive approach to a problem—uninfluenced by the methods everyone else has used—can be productive. This paper describes such an approach to a real-world problem, using only what is known by the teacher of the introductory, calculus-based physics course. The intent of this paper is to encourage students and teachers of physics to look for unconventional areas, outside of physics, where they might use the techniques they have learned to solve problems

Early History of BELL'S Theorem Theory and Experiment

NASA Astrophysics Data System (ADS)

Clauser, John F.

Before 1980 it was unfashionable for a physicist to admit that he either did not understand and/or doubted the Truth and/or Orthodoxy of Quantum Mechanics (QM). Contemporary wisdom deemed it impossible that it may lead to incorrect predictions. Thus, it was foolish to suggest that it warranted further testing. Said wisdom proclaimed that nothing would ever be gained by any such pursuit. Bohr had won his debates with Einstein. Von Neumann had proven all other interpretations wrong. That was the end to it! Only an iconoclast dared think otherwise. Here I provide a brief history of some of my encounters with a few fellow iconoclasts, past denizens of a QM doubter's subculture.

Shortly after its foundation in 1956 the Joint Institute for Nuclear Research in Dubna became an important training place for young physicists from Eastern-European countries. In those years I, too, was much younger than now, and from the late 1950s until the mid-1980s visited the Laboratory of Theoretical Physics many times for a few weeks. Discussions with Yakov Abramovich about particle physics and field theory were always interesting and instructive. When flavor SU(3) symmetry was discovered, his Dubna reprint review on the subject for me - and I think not only for me - proved to be a very helpful handbook during many subsequent years. Let me also tell you about an episode which I remember with gratitude...

The case for biophysics super-groups in physics departments.

Hoogenboom, Bart W; Leake, Mark

2018-06-04

Increasing numbers of physicists engage in research activities that address biological questions from physics perspectives or strive to develop physics insights from active biological processes. The on-going development and success of such activities morph our ways of thinking about what it is to 'do biophysics' and add to our understanding of the physics of life. Many scientists in this research and teaching landscape are homed in physics departments. A challenge for a hosting department is how to group, name and structure such biophysicists to best add value to their emerging research and teaching but also to the portfolio of the whole department. Here we discuss these issues and speculate on strategies. Creative Commons Attribution license.

Planck, the Quantum, and the Historians

NASA Astrophysics Data System (ADS)

Gearhart, Clayton A.

2002-05-01

In late 1900, the German theoretical physicist Max Planck derived an expression for the spectrum of black-body radiation. That derivation was the first step in the introduction of quantum concepts into physics. But how did Planck think about his result in the early years of the twentieth century? Did he assume that his derivation was consistent with the continuous energies inherent in Maxwellian electrodynamics and Newtonian mechanics? Or did he see the beginnings, however tentative and uncertain, of the quantum revolution to come? Historians of physics have debated this question for over twenty years. In this article, I review that debate and, at the same time, present Planck's achievement in its historical context.

Case study of a successful learner's epistemological framings of quantum mechanics

NASA Astrophysics Data System (ADS)

Dini, Vesal; Hammer, David

2017-06-01

Research on student epistemologies in introductory courses has highlighted the importance of understanding physics as "a refinement of everyday thinking" [A. Einstein, J. Franklin Inst. 221, 349 (1936), 10.1016/S0016-0032(36)91047-5]. That view is difficult to sustain in quantum mechanics, for students as for physicists. How might students manage the transition? In this article, we present a case study of a graduate student's approaches and reflections on learning over two semesters of quantum mechanics, based on a series of nine interviews. We recount his explicit grappling with the shift in epistemology from classical to quantum, and we argue that his success in learning largely involved his framing mathematics as expressing physical meaning. At the same time, we show he was not entirely stable in these framings, shifting away from them in particular during his study of scattering. The case speaks to literature on students' epistemologies, with respect to the roles of everyday thinking and mathematics. We discuss what this case suggests for further research, with possible implications for instruction.

Computer Supported Collaborative Rocketry: Teaching students to distinguish good and bad data like expert physicists

2013-10-01

Each year our physical science class for pre-service elementary teachers launches water-powered rockets based on the activity from NASA. We analyze the rocket flight using data from frame-by-frame video analysis of the launches. Before developing the methods presented in this paper, we noticed our students were mired in calculation details while losing sight of physical concepts. Sloppy measurements and calculations (even when using spreadsheets with formulas provided) sometimes led to such poor results that physical concepts could not be reliably taught from the data, but students were unmotivated to either notice or correct their errors. We adopted a collaborative, computer supported approach using simple and easily available functions in Google Spreadsheets to pool observations, provide instant feedback, and publicly display results from all teams side-by-side in real time. These instant comparisons promote student accountability and engagement, inspiring them to think more carefully about why answers may be different and notice sloppy data or unlikely outcomes—in short, to facilitate and motivate expert thinking about data.

As an undergraduate physics major who spent 2015 deep in a quantum optics lab at Oak Ridge National Laboratory, I knew my 2016 experience with the House of Representatives Energy and Commerce Committee would be a completely new challenge. I have long had a passion for the bridge of communication between the technical and non-technical worlds but it was only through my AIP Mather internship this summer that I was able to see that passion come to life in the realm of science policy. Suddenly, I went from squeezing political philosophy classes into my packed schedule to witnessing the political process first-hand. I was thrilled to find that the skills of critical thinking and communicating complex issues I have developed throughout my training as a physicist were directly applicable to my work in Congress. Overall, my experience this summer has given me insight into the inner workings of the federal policy process, deepened my appreciation for the work of government employees to keep Congressional members informed on the pressing current issues, and exposed me to a whole range of alternative careers within science.

Highlighting Successful Strategies for Engaging Minority Students in the Geosciences

Igniting interest and creativity in students for the geosciences oftentimes require innovation, bold `outside-the-box' thinking, and perseverance, particularly for minority students for whom the preparation for the discipline and its lucrative pathways to the geoscience workforce are regrettably unfamiliar and woefully inadequate. The enrollment, retention, participation, and graduation rates of minority students in STEM generally and in the geosciences particularly remain dismally low. However, a coupled, strategic geoscience model initiative at the New York City College of Technology (City Tech) of the City University of New York has been making steady in-roads of progress, and it offers practical solutions to improve minority student engagement in the geosciences. Aided by funding from the National Science Foundation (NSF), two geoscience-centric programs were created from NSF REU and NSF IUSE grants, and these programs have been successfully implemented and administered at City Tech. This presentation shares the hybrid geoscience research initiatives, the multi-tiered mentoring structures, the transformative geoscience workforce preparation, and a plethora of other vital bastions of support that made the overall program successful. Minority undergraduate scholars of the program have either moved on to graduate school, to the geoscience workforce, or they persist with greater levels of success in their STEM disciplines.

Complexity for Survival of Living Systems

NASA Technical Reports Server (NTRS)

Zak, Michail

2009-01-01

A logical connection between the survivability of living systems and the complexity of their behavior (equivalently, mental complexity) has been established. This connection is an important intermediate result of continuing research on mathematical models that could constitute a unified representation of the evolution of both living and non-living systems. Earlier results of this research were reported in several prior NASA Tech Briefs articles, the two most relevant being Characteristics of Dynamics of Intelligent Systems (NPO- 21037), NASA Tech Briefs, Vol. 26, No. 12 (December 2002), page 48; and Self-Supervised Dynamical Systems (NPO- 30634) NASA Tech Briefs, Vol. 27, No. 3 (March 2003), page 72. As used here, living systems is synonymous with active systems and intelligent systems. The quoted terms can signify artificial agents (e.g., suitably programmed computers) or natural biological systems ranging from single-cell organisms at one extreme to the whole of human society at the other extreme. One of the requirements that must be satisfied in mathematical modeling of living systems is reconciliation of evolution of life with the second law of thermodynamics. In the approach followed in this research, this reconciliation is effected by means of a model, inspired partly by quantum mechanics, in which the quantum potential is replaced with an information potential. The model captures the most fundamental property of life - the ability to evolve from disorder to order without any external interference. The model incorporates the equations of classical dynamics, including Newton s equations of motion and equations for random components caused by uncertainties in initial conditions and by Langevin forces. The equations of classical dynamics are coupled with corresponding Liouville or Fokker-Planck equations that describe the evolutions of probability densities that represent the uncertainties. The coupling is effected by fictitious information-based forces that are gradients of the information potential, which, in turn, is a function of the probability densities. The probability densities are associated with mental images both self-image and nonself images (images of external objects that can include other agents). The evolution of the probability densities represents mental dynamics. Then the interaction between the physical and metal aspects of behavior is implemented by feedback from mental to motor dynamics, as represented by the aforementioned fictitious forces. The interaction of a system with its self and nonself images affords unlimited capacity for increase of complexity. There is a biological basis for this model of mental dynamics in the discovery of mirror neurons that learn by imitation. The levels of complexity attained by use of this model match those observed in living systems. To establish a mechanism for increasing the complexity of dynamics of an active system, the model enables exploitation of a chain of reflections exemplified by questions of the form, "What do you think that I think that you think...?" Mathematically, each level of reflection is represented in the form of an attractor performing the corresponding level of abstraction with more details removed from higher levels. The model can be used to describe the behaviors, not only of biological systems, but also of ecological, social, and economics ones.

The happiest thought of Einstein's life.

NASA Astrophysics Data System (ADS)

Heller, M.

It is a commonly told story that Einstein formulated his famous principle of equivalence when thinking about what happens in a freely falling elevator, and that it was an original idea of his genius distinguished by the rare capability to see deep problems in the most ordinary things. In the reading of Einstein's and Ernst Mach's works the author has discovered that it was not a physicist in an elevator which led to the principle of equivalence but rather somebody falling from a roof; moreover, the idea behind the principle was not invented by Einstein himself but rather read by him from the book by Mach entitled The Science of Mechanics. The influence this book had on young Einstein is very well known.

Perspectives on theory at the interface of physics and biology.

2018-01-01

Theoretical physics is the search for simple and universal mathematical descriptions of the natural world. In contrast, much of modern biology is an exploration of the complexity and diversity of life. For many, this contrast is prima facie evidence that theory, in the sense that physicists use the word, is impossible in a biological context. For others, this contrast serves to highlight a grand challenge. I am an optimist, and believe (along with many colleagues) that the time is ripe for the emergence of a more unified theoretical physics of biological systems, building on successes in thinking about particular phenomena. In this essay I try to explain the reasons for my optimism, through a combination of historical and modern examples.

Although the term STAT conveys a sense of urgency, it is sometimes used to circumvent a system that may be too slow to accomplish tasks in a timely manner. We describe a quality-improvement project undertaken by a US Department of Veterans Affairs (VA) hospital to improve the STAT medication process. We adapted A3 Thinking, a problem-solving process common in Lean organizations, to our problem. In the discovery phase, a color-coded flow map of the existing process was constructed, and a real-time STAT order was followed in a modified "Go to the Gemba" exercise. In the envisioning phase, the team brainstormed to come up with as many improvement ideas as possible, which were then prioritized based on the anticipated effort and impact. The team then identified initial experiments to be carried out in the experimentation phase; each experiment followed a standard Plan-Do-Study-Act cycle. On average, the number of STAT medications ordered per month decreased by 9.5%. The average time from STAT order entry to administration decreased by 21%, and time from medication delivery to administration decreased by 26%. Improvements were also made in technician awareness of STAT medications and nurse notification of STAT medication delivery. Adapting A3 Thinking for process improvement was a low-cost/low-tech option for a VA facility. The A3 Thinking process led to a better understanding of the meaning of STAT across disciplines, and promoted a collaborative culture in which other hospital-wide problems may be addressed in the future.

Large-scale Assessment Yields Evidence of Minimal Use of Reasoning Skills in Traditionally Taught Classes

NASA Astrophysics Data System (ADS)

Thacker, Beth

2017-01-01

Large-scale assessment data from Texas Tech University yielded evidence that most students taught traditionally in large lecture classes with online homework and predominantly multiple choice question exams, when asked to answer free-response (FR) questions, did not support their answers with logical arguments grounded in physics concepts. In addition to a lack of conceptual understanding, incorrect and partially correct answers lacked evidence of the ability to apply even lower level reasoning skills in order to solve a problem. Correct answers, however, did show evidence of at least lower level thinking skills as coded using a rubric based on Bloom's taxonomy. With the introduction of evidence-based instruction into the labs and recitations of the large courses and in a small, completely laboratory-based, hands-on course, the percentage of correct answers with correct explanations increased. The FR format, unlike other assessment formats, allowed assessment of both conceptual understanding and the application of thinking skills, clearly pointing out weaknesses not revealed by other assessment instruments, and providing data on skills beyond conceptual understanding for course and program assessment.

Design Considerations for High Energy Electron -- Positron Storage Rings

DOE R&D Accomplishments Database

Richter, B.

1966-11-01

High energy electron-positron storage rings give a way of making a new attack on the most important problems of elementary particle physics. All of us who have worked in the storage ring field designing, building, or using storage rings know this. The importance of that part of storage ring work concerning tests of quantum electrodynamics and mu meson physics is also generally appreciated by the larger physics community. However, I do not think that most of the physicists working tin the elementary particle physics field realize the importance of the contribution that storage ring experiments can make to our understanding of the strongly interacting particles. I would therefore like to spend the next few minutes discussing the sort of things that one can do with storage rings in the strongly interacting particle field.

Charles Darwin: genius or plodder?

PubMed

Wilkins, Adam S

2009-11-01

There is no doubt about the magnitude of Charles Darwin's contributions to science. There has, however, been a long-running debate about how brilliant he was. His kind of intelligence was clearly different from that of the great physicists who are deemed geniuses. Here, the nature of Darwin's intelligence is examined in the light of Darwin's actual style of working. Surprisingly, the world of literature and the field of neurobiology might supply more clues to resolving the puzzle than conventional scientific history. Those clues suggest that the apparent discrepancy between Darwin's achievements and his seemingly pedestrian way of thinking reveals nothing to Darwin's discredit but rather a too narrow and inappropriate set of criteria for "genius." The implications of Darwin's particular creative gifts with respect to the development of scientific genius in general are briefly discussed.

An LLNL team of six physicists has developed a new technology that is a stepping stone to enable some of the limitations on high-power fiber lasers to be overcome. Their technology, dubbed "Efficient Mode-Converters for High-Power Fiber Amplifiers," allows the power of fiber lasers to be increased while maintaining high beam quality. Currently, fiber lasers are used in machining, on factory floors and in a number of defense applications and can produce tens of kilowatts of power.The conventional fiber laser design features a circular core and has fundamental limitations that make it impractical to allow higher laser power unless the core area is increased. LLNL researchers have pioneered a design to increase the laser's core area along the axis of the ribbon fiber. Their design makes it difficult to use a conventional laser beam, so the LLNL team converted the beam into a profile that propagates into the ribbon fiber and is converted back once it is amplified. The use of this LLNL technology will permit the construction of higher power lasers for lower costs and increase the power of fiber lasers from tens of kilowatts of power to about 100 kilowatts and potentially even higher.

The efficiency of radiotherapy treatment for cancer patients and use of the state-of-the-art accelerator facilities, in the first place, depends on the qualification and number of medical physicists. The need for the training and continuing professional development (CPD) of medical radiation physicists in Russia and CIS countries has dramatically increased today. The article considers the system of refresher training which should provide the continuing professional development and advance training of medical radiation physicists. The authors analyze the experience of the International Educational Center of the Association of Medical Physicists in Russia involved in the CPD of medical physicists under the IAEA TC projects, RMAPO and N.N. Blokhin RCRC joint educational programs.

IN MY OPINION: Physics is fun - for whom?

NASA Astrophysics Data System (ADS)

Allday, Jonathan

1998-09-01

King's School, Canterbury, UK I'm compiling a physics joke book. So far I have one entry. How do you tell the difference between a physicist and an applied mathematician? You do an experimental test. You get them to make a cup of tea. You provide water, a kettle, a teabag, a teapot and a cup. The physicist goes into the room, fills the kettle with water and boils the water. She then places the teabag in the teapot and pours on the boiling water - thus a cup of tea is made. You then restore the initial conditions and send in the applied mathematician. He proceeds to do the same thing. Now, you make the test slightly harder. You fill the kettle with water prior to the subjects arriving. The physicist notes this, boils the water in the kettle and makes tea as before. The applied mathematician sees that the kettle is full of water, empties the kettle so reducing the situation to the previous problem, which he has already solved. When I first heard this I thought that it was rather funny. Since then, observation seems to suggest that I may well be the only person on the planet who thinks that it is at all funny, so I do not anticipate great sales for my joke book - if I ever find another joke to put in it. I am having rather better luck with the book of physics cartoons. I have been collecting physics-related cartoons for about 15 years now and have a substantial stock. Surprisingly I used to find Punch a rich vein of such material. These days I tend to rely on Larson's Far Side for providing new samples. Students are still bemused by the fact that at least one of his cartoons can reduce me to helpless laughter. I have it pinned to the wall in my lab - two scientists are in animated conflict over a pile of burning machinery in the middle of a desert. A caveman is observing from a distance. The caption reads `tempers flair when Professors Carson and Lazell, working independently, ironically set their time machines to identical coordinates'. Rather more telling is the (modified) Punch cartoon. Marcie and Linus are discussing life: Marcie `Thank you for the Chocolate Sundae, Linus' Linus `You're welcome... Maybe we can do it again sometime?' Marcie `I don't think so... I don't find you very interesting.' Linus, wistfully and leaning against a tree - `Physics....' This cartoon the students find funny. The fact that the study of physics should be a block to a meaningful relationship seems to strike a chord with them. It takes them by surprise that physicists have a real life. Now I realize that any teacher having a real life often takes students by surprise. I remember visiting my mother's infants school when I was a sixth-former and the kids there found it unbelievable that Mrs Allday should have a son. Teachers, you see, cease to exist the minute the students walk out of the classroom. However, physics and its practitioners seem to be especially branded in this way. From time to time I show videos to my students. Well chosen ones (so I think) that reflect modern developments and show physicists enjoying what they are doing. One such tape shows the reaction to the first pictures coming down from the newly repaired Hubble Space Telescope. The control room is filled with whoops, delighted cheering and general bouncing up and down with enthusiasm. This always raises a laugh. However, one can tell that they are being laughed at, not with. Another tape is about the comet strike on Jupiter. The narrator spends some time talking with Gene and Carolyn Shoemaker (two of the discoverers of the comet) - a married team of astronomers. You can see that their married life in part revolves round their joint love of astronomy and physics. I have overheard comments like `can you imagine the breakfast conversations?' Why do students find it so difficult to imagine that physicists in real life have fun doing physics? Pondering this I have come to the conclusion that they do not see enough teachers having fun teaching the subject. Perhaps with all the time we have spent trying to modernize our syllabuses, introducing new interesting physics, making physics fun for the students, we have forgotten to think about ourselves. I have had a theory for some years which is that students are never naturally interested in a subject - they are interested in a teacher first, and then the subject follows. Goodness knows, these days with investigations, modular examinations and the general paperwork that flows in the job, it is hard enough to find enough time to breathe let alone have fun. However, I am becoming increasingly convinced that it is vital. I propose that we use the declining numbers doing physics to our advantage. With smaller set sizes we can spend more time doing things that we enjoy. In my department we regularly ask sixth-formers why they chose Chemistry and Biology as A-levels rather than Physics. The common answer is that Physics is harder. Yes, it is. That is the nature of the science. There is nothing we can do about it. Physics is difficult, otherwise we would not need people of the stature of Newton and Einstein to do it! However, it's a lot more fun. There is a nice story about Feynman. He was being shown round CERN and was brought into one of the underground experimental chambers. Faced with a giant detector he turned to his guide and asked what it was for. After some explanation the guide finally broke down and apologised - he had forgotten that the experiment was designed to test one of the theories that Feynman had had a significant hand in. `Really' said Feynman, `and how much did this cost?'. `Thirty million dollars' came the reply. Feynman turned to his guide, looked at him in all seriousness and said `don't you trust me?' Now there was a man that had fun doing physics - and he let everyone know it.

Charles Darwin: Genius or Plodder?

PubMed Central

Wilkins, Adam S.

2009-01-01

There is no doubt about the magnitude of Charles Darwin's contributions to science. There has, however, been a long-running debate about how brilliant he was. His kind of intelligence was clearly different from that of the great physicists who are deemed geniuses. Here, the nature of Darwin's intelligence is examined in the light of Darwin's actual style of working. Surprisingly, the world of literature and the field of neurobiology might supply more clues to resolving the puzzle than conventional scientific history. Those clues suggest that the apparent discrepancy between Darwin's achievements and his seemingly pedestrian way of thinking reveals nothing to Darwin's discredit but rather a too narrow and inappropriate set of criteria for “genius.” The implications of Darwin's particular creative gifts with respect to the development of scientific genius in general are briefly discussed.

Someone from the Huffington Post just called you because they are doing a story about science and you are a physicist. The problem is that they need you to take time away from your grapheme experiments to talk about the physics of exploding anvils. It's been a long time since you've shot an anvil in the air so you think you might not be right for this. But, as long as you understand general physics and can explain things well, you can be a real asset. This talk will recount first-hand experiences talking to a range of news outlets from the PBS New Hour to Real Simple Magazine about everything from quick-freezing water to pumpkin boats. It will include helpful information about preparing for an interview, learning new physics fast, timelines and follow-up.

Replacing textbook problems with lab experiences

NASA Astrophysics Data System (ADS)

Register, Trevor

2017-10-01

End-of-the-chapter textbook problems are often the bread and butter of any traditional physics classroom. However, research strongly suggests that students be given the opportunity to apply their knowledge in multiple contexts as well as be provided with opportunities to do the process of science through laboratory experiences. Little correlation has been shown linking the number of textbook problems solved with conceptual understanding of topics in mechanics. Furthermore, textbook problems as the primary source of practice for students robs them of the joy and productive struggle of learning how to think like an experimental physicist. Methods such as Modeling Instruction tackle this problem head-on by starting each instructional unit with an inquiry-based lab aimed at establishing the important concepts and equations for the unit, and this article will discuss ideas and experiences for how to carry that philosophy throughout a unit.

Technological advances and increased utilization of medical testing and procedures have prompted greater attention to ensuring the patient safety of radiation use in the practice of adult cardiovascular medicine. In response, representatives from cardiovascular imaging societies, private payers, government and nongovernmental agencies, industry, medical physicists, and patient representatives met to develop goals and strategies toward this end; this report provides an overview of the discussions. This expert "think tank" reached consensus on several broad directions including: the need for broad collaboration across a large number of diverse stakeholders; clarification of the relationship between medical radiation and stochastic events; required education of ordering and providing physicians, and creation of a culture of safety; development of infrastructure to support robust dose assessment and longitudinal tracking; continued close attention to patient selection by balancing the benefit of cardiovascular testing and procedures against carefully minimized radiation exposures; collation, dissemination, and implementation of best practices; and robust education, not only across the healthcare community, but also to patients, the public, and media. Finally, because patient radiation safety in cardiovascular imaging is complex, any proposed actions need to be carefully vetted (and monitored) for possible unintended consequences.

The objects of the empirical science known as particle physics are not like objects ordinarily conceived. Physicists' particles can enter states strangely entangled with those of other particles; they can obey statistics which suggest that they lack genidentity; their properties (some think) are created in measurement, or (others think) can only be limned from the symmetries of the theory describing them. 'The implications of contemporary physical theories for the debate on the nature of objects' provides 'the central theme' (p. 4) of Interpreting Bodies, editor Elena Castellani's new collection of essays. Contributions to the volume vary dramatically in vintage (Born's and Reichenbach's are well into middle age; others appear here for the first time); in approach (the collection includes Giuliano Toraldo diFrancia's nine-page history of the object concept from Democritus to d'Espagnat, Peter Mittelstaedt's discussion of the Kantian constitution of quantum objects, and Giulo Peruzzi's explication of the scattering cross section and its role in experimental particle physics); and in intended audience. Lacking the space to treat each contribution in turn, I will focus on those dealing with the problem of the One and the Many.

What is Science?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Quinn, H.

Helen Quinn is a theoretical particle physicist at SLAC. Throughout her career, she has been passionately involved in science education and public understanding of science. In talking about science, whether to the public or to students, we scientists often assume that they share with us a common idea of science. In my experience that is often not the case. To oversimplify, scientists think of science both as a process for discovering properties of nature, and as the resulting body of knowledge, whereas most people seem to think of science, or perhaps scientists, as an authority that provides some information--just onemore » more story among the many that they use to help make sense of their world. Can we close that gap in understanding? Middle school teachers typically spend a day or so teaching something called the scientific method, but the process by which scientific ideas are developed and tested is messier and much more interesting than that typical capsule description. Some remarkable features of the process are seldom stressed in teaching science, nor are they addressed in explaining any one piece of science to the public. My goal in this column is to provide some ideas for closing that gap in understanding, and to encourage scientists and teachers to communicate about the process as they discuss scientific work.« less

Working (And Sparring) With Luis: Some Personal Recollections

NASA Astrophysics Data System (ADS)

Pripstein, Moishe

2011-04-01

Luis Alvarez was the most remarkable physicist I have ever worked with. As a member of his bubble chamber group at the Lawrence Radiation Laboratory in Berkeley and subsequently as a leader of that group for several years, I could appreciate his outstanding attributes as a physicist and his forceful and colorful personality. Each day at the lab seemed exciting. Although he created the largest research group in particle physics in the world at the time, Luis was an ardent foe of group-think, which he characterized as ``intellectual phase-lock''. He had an uncanny intuition about physics and technology, coupled with an insatiable curiosity about the world around him. He is justly renowned as a member of the Inventors Hall of Fame for his myriad inventions and as a Nobel Laureate in physics for his contributions to particle physics through his development of the hydrogen bubble chamber technique, leading to the discovery of a large number of resonance states. However, it was his wide-ranging curiosity which led him to one of his finest achievements, while working with his son Walter - developing the asteroid impact theory as the explanation of the extinction of the dinosaurs. I will offer some personal recollections of Luis and the group in this period, including some of his other intriguing efforts which illustrate the breadth of his interests, pertaining to the Kennedy assassination and x-raying the pyramids, among them. All in all, a brilliant and most unusual scientist and stimulating colleague.

Skating on Thin Ice: Evolution of Conservation in Energy Policy

NASA Astrophysics Data System (ADS)

Gibbons, Jack

2009-05-01

Why are we physicists so often drawn into the nexus of energy policy and governance? There are several explanations. First, we are quite accustomed to this phenomenon of ``cause and effect,'' so we instinctively examine those two ends as well as the connections between them (i.e., what happens between a lump of coal and a light bulb). That way of thinking makes energy production and consumption intiminately connected and ``conservation'' naturally becomes a technological strategy rather than an appendage. Strangely, however, ``conservation'' in our society (called ``The Cowboy Economy'' by economist Kenneth Boulding) has been widely interpreted as competitive with supply and ridiculed as only a minor option, entailing denial of an amenity. After nearly a half-century of dialogue, innovation, and frustration, the rationality of what I call the ``physics'' perspective seems to have come of age. The evolution of relevant science and technology and public policy has advanced markedly, reflected and sustained at the national level by a succession of organizations. The Congressional Office of Technology Assessment, the Federal Office of Energy Conservation, the Federal Energy Administration, the U.S. Department of Energy, and the Office of Science and Technology Policy. Not surprisingly, physicists continue to play key roles in the inculcation of science and analysis into the policy and governance. This requires, as implied by C.P. Snow, a bridging and strengthening of the thin ice between science and society. We still have a long road to travel.

For the last twenty years, issues of the digital divide have driven efforts around the world to address the lack of access to computers and the Internet, pertinent and language appropriate content, and technical skills in low-income communities (Schuler & Day, 2004a and b). The title of our paper makes reference to a milestone publication (Schon, Sanyal, & Mitchell, 1998) that showcased some of the early work and thinking in this area. Schon, Sanyal and Mitchell's book edition included an article outlining the Computer Clubhouse, a type of community technology center model, which was developed to create opportunities for youth in low-income communities to become creators and designers of technologies by (1998). The model has been very successful scaling up, with over 110 Computer Clubhouses now in existence worldwide.

To standardize educational programs and clinical training for medical physics students, the Japanese Board for Medical Physicist Qualification (JBMP) began to accredit master's, doctorate, and residency programs for medical physicists in 2012. At present, 16 universities accredited by the JBMP offer 22 courses. In this study, we aimed to survey the current status of educational programs and career paths of students after completion of the medical physicist program in Japan. A questionnaire was sent in August 2014 to 32 universities offering medical physicist programs. The questionnaire was created and organized by the educational course certification committee of the JBMP and comprised two sections: the first collected information about the university attended, and the second collected information about characteristics and career paths of students after completion of medical physicist programs from 2008 to 2014. Thirty universities (16 accredited and 14 non-accredited) completed the survey (response rate 94 %). A total of 209, 40, and 3 students graduated from the master's, doctorate, and residency programs, respectively. Undergraduates entered the medical physicist program constantly, indicating an interest in medical physics among undergraduates. A large percentage of the students held a bachelor's degree in radiological technology (master's program 94 %; doctorate program 70 %); graduates obtained a national radiological technologist license. Regarding career paths, although the number of the graduates who work as medical physicist remains low, 7 % with a master's degree and 50 % with a doctorate degree worked as medical physicists. Our results could be helpful for improving the medical physicist program in Japan.

The focus of work of medical physicists in 1980’s was on quality control and quality assurance. Radiation safety was important but was dominated by occupational radiation protection. A series of over exposures of patients in radiotherapy, nuclear medicine and observation of skin injuries among patients undergoing interventional procedures in 1990’s started creating the need for focus on patient protection. It gave medical physicists new directions to develop expertise in patient dosimetry and dose management. Publications creating awareness on cancer risks from CT in early part of the current century and over exposures in CT in 2008 brought radiation risks inmore » public domain and created challenging situations for medical physicists. Increasing multiple exposures of individual patient and patient doses of few tens of mSv or exceeding 100 mSv are increasing the role of medical physicists. Expansion of usage of fluoroscopy in the hands of clinical professionals with hardly any training in radiation protection shall require further role for medical physicists. The increasing publications in journals, recent changes in Safety Standards, California law, all increase responsibilities of medical physicists in patient protection. Newer technological developments in dose efficiency and protective devices increase percentage of time devoted by medical physicists on radiation protection activities. Without radiation protection, the roles, responsibilities and day-to-day involvement of medical physicists in diagnostic radiology becomes questionable. In coming years either medical radiation protection may emerge as a specialty or medical physicists will have to keep major part of day-to-day work on radiation protection. Learning Objectives: To understand how radiation protection has been increasing its role in day-to-day activities of medical physicist To be aware about international safety Standards, national and State regulations that require higher attention to radiation protection than in past To be aware about possible emergence of medical radiation protection as a specialty and challenges for medical physicists.« less

Grain Flow at High Stresses

NASA Astrophysics Data System (ADS)

McSaveney, M. J.

2015-12-01

The transport mechanism of rapid long-runout rock avalanches was a hotly debated topic when I came on the scene in 1967. So how come it is still debated today? My explanation is that it is the expected outcome of peer review, poor comprehension, and technological advances outpacing intellectual advances. Why think about the problem when we can model it! So let us think about the problem. Shreve thought that rock avalanches fell upon and trapped a layer of air. What physics was he thinking about? It is how feathers and tissue papers fall. When my rock avalanches fly, they fly like unlubricated bricks using the physics of projectiles and ballistics. But the main transport mechanism is not flight. The dominant impression from watching a rock avalanche in motion is of fluid flow, as Heim described it in 1882. A rock avalanche is a very large grain flow. Bagnold studied dispersive grain flows, but why should one assume that rock avalanches are dispersive grain flows as many do. The more common grain flow type is a dense grain flow and rock avalanches are dense grain flows in which the weight can and does generate very high stresses at grain contacts. Brittle rock deforms elastically up to its compressive strength, whereupon it breaks, releasing elastic strain as transient elastic strain (seismic energy to a seismologist, acoustic energy to a physicist). Melosh and others have shown that acoustic energy can fluidize a grain mass. There is no exotic physics behind grain flow at high stress. When grains break, the released elastic strain has to go somewhere, and it goes somewhere principally by transmission though grain contacts. Depending on the state of stress at the grain contact, the contact will pass the stress or will slip at conventional values of Coulomb friction. Enough thinking! A physical model of the entire process is too big for any laboratory. So whose numerical model will do it?

Based on characteristics of high-tech industry in Northeast China, high-tech industry competitiveness index system was developed, and the competitiveness of high-tech industry was evaluated through principal component analysis and location quotient method. The results showed that the scale of high-tech industry in Northeast China as a whole was small, and presented a decreasing trend for the proportion in the country. The competitiveness of high-tech industry in Northeast China lagged far behind that of the eastern and central regions. The high-tech industry competitiveness of Liaoning, Jilin and Heilongjiang provinces in China ranked 15, 19 and 21, respectively. The manufacture of medicine in Jilin province, and the manufacture of aircraft and spacecraft and the related equipment in Liaoning and Heilongjiang provinces had high competitive advantage, but the manufacture of electronic equipment and communication equipment and the manufacture of computers and office equipment was lack of competitiveness. The development suggestions were put forward to improve the competitiveness of high-tech industries in Northeast China.

What is a physicist? A case is made for defining a physicist as anyone with a bachelor's degree (or higher) in physics. Under this definition, a large fraction of physicists are hidden, that is, they have left, or never belonged to, the traditional lot of Ph.D. academicians. Data from the Statistical Research Center at the American Institute of Physics and from a survey of members of the national physics honor society, Sigma Pi Sigma, show the vast array of actual career paths taken by physicists. From spandex to blackberries to bioinformatics to flight control to wind energy to spintronics, physicists can be found in nearly every job sector in some of the coolest and most farfetched careers imaginable.

Although the number of women physicists in Cuba, as in the entire world, is less than men physicists, their presence in the academic leadership is strong, unlike the limited women's role in many other countries. Some interesting numeral data are presented to demonstrate this affirmation. This fact emphasizes the advantages reached by women and the increasing prestige obtained by women physicists in our country.

Telementoring Physics: University-Community After-school Collaborations and the Mediation of the Formal/Informal Divide

NASA Astrophysics Data System (ADS)

Lecusay, Robert A.

For several decades improvement of science education has been a major concern of policy makers concerned that the U.S. is a "nation at risk" owing to the dearth of students pursing careers in science. Recent policy proposals have argued that provision of broadband digital connectivity to organizations in the informal sector would increase the reach of the formal, academic sector to raise the overall level of science literacy in the country. This dissertation reports on a longitudinal study of a physics telementoring activity jointly run by a university-community collaborative at a community learning center. The activity implemented a digital infrastructure that exceeds the technical and social-institutional arrangements promoted by policy makers. In addition to broadband internet access (for tele-conferencing between students at the community center and physicists at a university), supplemented by digital software designed to promote physics education, the activity included the presence of a collaborating researcher/tutor at the community learning center to coordinate and document the instructional activities. The current research revealed a fundamental contradiction between the logic, goals, and practices of the physics instructors, and the corresponding logic, goals, and practices of the participants at the community learning center. This contradiction revolves around a contrast between the physicists' formal, logocentric ways of understanding expressed in the ability to explain the scientific rules underlying physical phenomena and the informal, pragmatic orientation of the youth and adults at the learning center. The observations in this dissertation should remind techno-enthusiasts, especially in the arena of public education policy, that there are no turnkey solutions in "distance" science education. Technically "connecting" people is not equivalent to creating conditions that expand opportunities to learn and a functioning socio-technical system that supports learning. Secondly, for designers and practitioners of informal learning in community-university collaborative settings, it is critically important to understand distance learning activities as developing "cross-cultural, " collaborative encounters, the results of which are more likely to be hybrids of different ways of learning and knowing than the conversion of informal learning into a tool for instruction that will allow youth to "think like physicists."

MO-E-213-03: Newer Radiation Protection Requirements in Last Decade

Clements, J.

The focus of work of medical physicists in 1980’s was on quality control and quality assurance. Radiation safety was important but was dominated by occupational radiation protection. A series of over exposures of patients in radiotherapy, nuclear medicine and observation of skin injuries among patients undergoing interventional procedures in 1990’s started creating the need for focus on patient protection. It gave medical physicists new directions to develop expertise in patient dosimetry and dose management. Publications creating awareness on cancer risks from CT in early part of the current century and over exposures in CT in 2008 brought radiation risks inmore » public domain and created challenging situations for medical physicists. Increasing multiple exposures of individual patient and patient doses of few tens of mSv or exceeding 100 mSv are increasing the role of medical physicists. Expansion of usage of fluoroscopy in the hands of clinical professionals with hardly any training in radiation protection shall require further role for medical physicists. The increasing publications in journals, recent changes in Safety Standards, California law, all increase responsibilities of medical physicists in patient protection. Newer technological developments in dose efficiency and protective devices increase percentage of time devoted by medical physicists on radiation protection activities. Without radiation protection, the roles, responsibilities and day-to-day involvement of medical physicists in diagnostic radiology becomes questionable. In coming years either medical radiation protection may emerge as a specialty or medical physicists will have to keep major part of day-to-day work on radiation protection.

‘Particle genetics’: treating every cell as unique

PubMed Central

Yvert, Gaël

2014-01-01

Genotype-phenotype relations are usually inferred from a deterministic point of view. For example, quantitative trait loci (QTL), which describe regions of the genome associated with a particular phenotype, are based on a mean trait difference between genotype categories. However, living systems comprise huge numbers of cells (the ‘particles’ of biology). Each cell can exhibit substantial phenotypic individuality, which can have dramatic consequences at the organismal level. Now, with technology capable of interrogating individual cells, it is time to consider how genotypes shape the probability laws of single cell traits. The possibility of mapping single cell probabilistic trait loci (PTL), which link genomic regions to probabilities of cellular traits, is a promising step in this direction. This approach requires thinking about phenotypes in probabilistic terms, a concept that statistical physicists have been applying to particles for a century. Here, I describe PTL and discuss their potential to enlarge our understanding of genotype-phenotype relations. PMID:24315431

Model-Free Views of Deep Inelastic Scattering

2014-11-01

Perhaps I should point out first that my choice of topic was dictated by the injunction that the nature of this symposium should revolve around subjects that might be conceivably of interest to Viki. Viki has, along with most high energy physicists been very interested in the subject of deep inelastic electron scattering. With his characteristic attention to directly visualizable approaches to physical phenomena, he has dealt with this in terms of rather specific models, attempting then to give very elementary explanations of these fascinating phenomena. I thought he might be interested to see the other side of the coin, namely, the extent to which one can correlate and comprehend these physical effects without the use of specific models. I think this may lend a certain useful balance to the way things are looked at these days. So my remarks are directed to Viki but you're all welcome to eavesdrop...

Many current public policy issues have a geoscience component: climate change, natural hazards, energy, and mineral resources to name just a few. In addition, Congress makes decisions that directly affect scientists, such as funding allocations and visa and travel policy. Yet few geoscientists are engaged in the policy-making process. Members of Congress have called on scientists to become more active, including Ph.D. physicist and former-Representative Vernon Ehlers (R-MI). In an address at the 2010 AAAS Forum on Science and Technology Policy, he told scientists, "The gulf between the scientifically minded and those who are not scientifically minded is still tremendous. I think we are keeping far too quiet about what we know and how we would go about solving problems. We have so much to offer this country à solutions to various difficulties." This talk will provide information on avenues for geoscientists to more effectively engage in the public policy arena.

Student use of model-based reasoning when troubleshooting an electronic circuit

2016-03-01

Troubleshooting systems is an integral part of experimental physics in both research and educational settings. Accordingly, ability to troubleshoot is an important learning goal for undergraduate physics lab courses. We investigate students' model-based reasoning on a troubleshooting task using data collected in think-aloud interviews during which pairs of students from two institutions attempted to diagnose and repair a malfunctioning circuit. Our analysis scheme was informed by the Experimental Modeling Framework, which describes physicists' use of mathematical and conceptual models when reasoning about experimental systems. We show that system and subsystem models were crucial for the evaluation of repairs to the circuit and played an important role in some troubleshooting strategies. Finally, drawing on data from interviews with electronics instructors from a broad range of institution types, we outline recommendations for model-based approaches to teaching and learning troubleshooting skills.

2008-06-01

In doing public programs, getting audiences to think about astronomy in the wider culture, or just having some fun with a class or museum group, it's useful to have them brainstorm about all the pieces of music they can identify that have an astronomical connection. We have found over 100 pieces of classical and popular music that draw their inspiration from serious astronomy (and not just the use of a single astronomical term). These include three rock songs about black holes, operas about Einstein and Kepler, an electronic piece in which the players are asked to expand like the universe, and many more. We also highlight several astronomers and physicists who perform science music and discuss how anyone can use music to catch audience interest.

A populist revolution began more than half a dozen years ago and culminated in the election of Donald Trump in 2016. I will link its evolution to the impacts of science and technology on jobs, as well as income and opportunity disparity; the role of tax policies and regulatory practices that reinforced the technological impacts; the capacity of information technology to fan the populist flames; and finally the accelerating pace of technological change that has been so unsettling for most Americans. As physicists, we're in for very challenging times that go far beyond Donald Trump. I began calling attention to the issues in the aftermath of the 2010 election and more pointedly after the 2014 vote. My audiences at universities and national laboratories, I think never fully grasped how fast the world was changing and what dangers for science were becoming increasingly evident.

Future trends in the supply and demand for radiation oncology physicists.

PubMed

Mills, Michael D; Thornewill, Judah; Esterhay, Robert J

2010-04-12

Significant controversy surrounds the 2012 / 2014 decision announced by the Trustees of the American Board of Radiology (ABR) in October of 2007. According to the ABR, only medical physicists who are graduates of a Commission on Accreditation of Medical Physics Education Programs, Inc. (CAMPEP) accredited academic or residency program will be admitted for examination in the years 2012 and 2013. Only graduates of a CAMPEP accredited residency program will be admitted for examination beginning in the year 2014. An essential question facing the radiation oncology physics community is an estimation of supply and demand for medical physicists through the year 2020. To that end, a Demand & Supply dynamic model was created using STELLA software. Inputs into the model include: a) projected new cancer incidence and prevalence 1990-2020; b) AAPM member ages and retirement projections 1990-2020; c) number of ABR physics diplomates 1990-2009; d) number of patients per Qualified Medical Physicist from Abt Reports I (1995), II (2002) and III (2008); e) non-CAMPEP physicists trained 1990-2009 and projected through 2014; f) CAMPEP physicists trained 1993-2008 and projected through 2014; and g) working Qualified Medical Physicists in radiation oncology in the United States (1990-2007). The model indicates that the number of qualified medical physicists working in radiation oncology required to meet demand in 2020 will be 150-175 per year. Because there is some elasticity in the workforce, a portion of the work effort might be assumed by practicing medical physicists. However, the minimum number of new radiation oncology physicists (ROPs) required for the health of the profession is estimated to be 125 per year in 2020. The radiation oncology physics community should plan to build residency programs to support these numbers for the future of the profession.

Postdoctoral Opportunities in Medical Physics

The medical physicist is a professional who specializes in the application of the concepts and methods of physics to the diagnosis and treatment of human disease. Medical physicists identify their primary discipline to be radiation therapy (78%), medical imaging (16%), nuclear medicine (3%), or radiation safety (2%). They state their primary responsibility to be clinical (78%), academic (9%), research (4%), etc. Correspondingly, medical physicists reveal their primarily employment to be a private hospital (42%), university hospital (32%), physicist's service group (9%), physician's service group (9%), industry (5%), and government (3%). The most frequent job of medical physicists is clinical radiation therapy physicist, whose clinical duties include: equipment acquisition, facility design, commissioning, machine maintenance, calibration and quality assurance, patient treatment planning, patient dose calculation, management of patient procedures, development of new technology, radiation safety, and regulatory compliance. The number of medical physicists in the United States can be estimated by the number of members of the American Association of Physicists in Medicine (AAPM), which has increased 5.5% annually since 1969, currently being 5,000. New positions plus retirements create a current need >300 new medical physicists per year, which exceeds supply. This is supported by the steady growth in average salaries, being 100,000 for PhDs entering the field and reaching 180,000. Graduate programs alone cannot meet demand, and physicists entering the field through postdoctoral training in medical physics remain important. Details of postdoctoral research programs and medical physics residency programs will provide direction to physics PhD graduates interested in medical physics.

Medical physics plays an essential role in modern medicine. This is particularly evident in cancer care where medical physicists are involved in radiotherapy treatment planning and quality assurance as well as in imaging and radiation protection. Due to the large variety of tasks and interests, medical physics is often subdivided into specialties such as radiology, nuclear medicine and radiation oncology medical physics. However, even within their specialty, the role of radiation oncology medical physicists (ROMPs) is diverse and varies between different societies. Therefore, a questionnaire was sent to leading medical physicists in most countries/areas in the Asia/Pacific region to determine the education, role and status of medical physicists. Answers were received from 17 countries/areas representing nearly 2800 radiation oncology medical physicists. There was general agreement that medical physicists should have both academic (typically at MSc level) and clinical (typically at least 2 years) training. ROMPs spent most of their time working in radiotherapy treatment planning (average 17 hours per week); however radiation protection and engineering tasks were also common. Typically, only physicists in large centres are involved in research and teaching. Most respondents thought that the workload of physicists was high, with more than 500 patients per year per physicist, less than one ROMP per two oncologists being the norm, and on average, one megavoltage treatment unit per medical physicist. There was also a clear indication of increased complexity of technology in the region with many countries/areas reporting to have installed helical tomotherapy, IMRT (Intensity Modulated Radiation Therapy), IGRT (Image Guided Radiation Therapy), Gamma-knife and Cyber-knife units. This and the continued workload from brachytherapy will require growing expertise and numbers in the medical physics workforce. Addressing these needs will be an important challenge for the future.

2014-04-03

An LLNL team of six physicists has developed a new technology that is a stepping stone to enable some of the limitations on high-power fiber lasers to be overcome. Their technology, dubbed "Efficient Mode-Converters for High-Power Fiber Amplifiers," allows the power of fiber lasers to be increased while maintaining high beam quality. Currently, fiber lasers are used in machining, on factory floors and in a number of defense applications and can produce tens of kilowatts of power.The conventional fiber laser design features a circular core and has fundamental limitations that make it impractical to allow higher laser power unless themore » core area is increased. LLNL researchers have pioneered a design to increase the laser's core area along the axis of the ribbon fiber. Their design makes it difficult to use a conventional laser beam, so the LLNL team converted the beam into a profile that propagates into the ribbon fiber and is converted back once it is amplified. The use of this LLNL technology will permit the construction of higher power lasers for lower costs and increase the power of fiber lasers from tens of kilowatts of power to about 100 kilowatts and potentially even higher.« less

Theory of Constraints for Services: Past, Present, and Future

NASA Astrophysics Data System (ADS)

Ricketts, John A.

Theory of constraints (TOC) is a thinking process and a set of management applications based on principles that run counter to conventional wisdom. TOC is best known in the manufacturing and distribution sectors where it originated. Awareness is growing in some service sectors, such as Health Care. And it's been adopted in some high-tech industries, such as Computer Software. Until recently, however, TOC was barely known in the Professional, Scientific, and Technical Services (PSTS) sector. Professional services include law, accounting, and consulting. Scientific services include research and development. And Technical services include development, operation, and support of various technologies. The main reason TOC took longer to reach PSTS is it's much harder to apply TOC principles when services are highly customized. Nevertheless, with the management applications described in this chapter, TOC has been successfully adapted for PSTS. Those applications cover management of resources, projects, processes, and finances.

Innovative Techniques for Teaching about Landslides and Triggered Landslide Events

NASA Astrophysics Data System (ADS)

Taylor, F. E.; Malamud, B. D.

2014-12-01

When we think of a landslide (mass wasting), both the public and scientists often envisage an individual movement of earth material down a slope. Yet, landslides often occur not as individuals, but as parts of a triggered landslide event. This is where a trigger (e.g., an earthquake or heavy rainfall) results in up to tens of thousands of landslides in a region in the minutes to days after the trigger. In this paper, we will present ideas for innovative demonstrations, teaching practicals and projects, ranging from low-cost low-tech to more advanced digital methods, to communicate the ideas of landslides and triggered landslide events to the public and students. This paper is aimed at those in secondary school/university education and the public sector looking for examples to interest and inform their respective audiences about landslides, triggered landslide events, and the importance and implications of considering landslides not just as individuals, but as populations.

WYKO grew out of the research my students and I did at the Optical Sciences Center at the University of Arizona, but it's origins actually started earlier at the Itek Corporation where I went to work after getting my PhD in optics at the University of Rochester. Founding, growing, and cashing out was an unbelievable experience that was more fun than I ever dreamed anything could be. In this talk I will discuss the formation, growth, and eventual selling of the WYKO Corporation to Veeco in 1997. Both the fun parts and the not so fun parts will be discussed. The biggest surprises experienced and what I think are the most important factors in growing a successful high-tech company will be described.

Some observations on the creative process and its relation to mourning and various forms of understanding.

PubMed

Székely, L

1983-01-01

Highly abstract thinking is the manifestation of the inner working of mental life, which in the present instance is the creative activity of a theoretical physicist. Events in the 'creative workshop' are traditionally not the focus of psychoanalytic inquiry. The study here begins with a description of the intrapsychic consequences of object loss and mourning and their specific outcome during a period of creative work. Three distinctive events can be considered as direct consequences of mourning: (1) The conceptualization of the 'little wave'. (2) The belief, that the 'little wave' is solely his invention. (3) The assumption made in the preconscious, that the 'little wave' is a stable one. (2) and (3) had turned out to be erroneous and had been corrected by Alpha subsequently. Thereafter the scope of the psychoanalytic inquiry widens to include the cognitive strategies employed by the physicist and their genetic link to the collective alternates in Greenacre's sense. One such cognitive strategy is dealt with, to which the term 'tangled hierarchy' is applied. This considers how thought or knowledge acquired at one level is transferred to another, or vice versa, with the aim of achieving some degree of isomorphy between them. Interactions between events within the realm of object relations and those which take place in the preconscious creative sphere are pointed out. The transitional stages of a creative product bear the mark of the specific features of object relations, conflicts and defences. The final product, however, does not exhibit these same marks.

Diagnostic medical physicists and their clinical activities.

PubMed

Cypel, Yasmin S; Sunshine, Jonathan H

2004-02-01

The primary objective of this study was to obtain basic, descriptive information about medical physicists involved in diagnostic radiology-related activities, the diagnostic-related activities that they performed, and the time spent on these activities. A survey was sent to a randomly selected sample of 1511 medical physicists from July through October 2001 using primarily e-mail methods; a total of 851 surveys was received, for a response rate of 56%. Of these, 427 were responses from physicists who do partly or only clinical diagnostic medical physics; it is this group for which results are presented. Fifty-four percent of the physicists who reported doing any clinical diagnostic medical physics performed clinical activities only in diagnostic medical physics. Fourteen percent of all those doing clinical diagnostic medical physics were women. Over 97% of the physicists doing clinical diagnostic medical physics reported having graduate degrees in physics; 53% had PhDs. The mean total weekly hours worked by physicists doing clinical diagnostic medical physics was 42. Medical physicists doing only clinical diagnostic activities reported working approximately 40 hours weekly, whereas those doing partly clinical diagnostic medical physics reported working 14 hours weekly in the field (approximately one-third of their work time). Radiography and fluoroscopy, computed tomography, nuclear medicine, and mammography are all fields in which the majority of those doing any clinical diagnostic medical physics are active. Full-time physicists working only in diagnostic medical physics were responsible for a median of 25 units of equipment, compared with a median of 10 units for those working only partly in the field. Number of units evaluated, frequency of evaluation, and hours per evaluation were reported for almost 20 types of equipment. Medical physicists performing diagnostic clinical activities typically are responsible for a large number and wide variety of imaging equipment. It would be helpful to study their work further, focusing in particular on whether there is a shortage, as is true of diagnostic radiologists, and whether the variety of responsibilities creates strain.

SU-E-P-01: An Informative Review On the Role of Diagnostic Medical Physicist in the Academic and Private Medical Centers

DOE Office of Scientific and Technical Information (OSTI.GOV)

Weir, V; Zhang, J

Purpose: The role of physicist in the academic and private hospital environment continues to evolve and expand. This becomes more obvious with the newly revised requirements of the Joint Commission (JC) on imaging modalities and the continued updated requirements of ACR accreditation for medical physics (i.e., starting in June 2014, a physicists test will be needed before US accreditation). We provide an informative review on the role of diagnostic medical physicist and hope that our experience will expedite junior physicists in understanding their role in medical centers, and be ready to more opportunities. Methods: Based on our experience, diagnostic medicalmore » physicists in both academic and private medical centers perform several clinical functions. These include providing clinical service and physics support, ensuring that all ionizing radiation devices are tested and operated in compliance with the State and Federal laws, regulations and guidelines. We also discuss the training and education required to ensure that the radiation exposure to patients and staff is as low as reasonably achievable. We review the overlapping roles of medical and health physicist in some institutions. Results: A detailed scheme on the new requirements (effective 7/1/2014) of the JC is provided. In 2015, new standards for fluoroscopy, cone beam CT and the qualifications of staff will be phased in. A summary of new ACR requirements for different modalities is presented. Medical physicist have other duties such as sitting on CT and fluoroscopy committees for protocols design, training of non-radiologists to meet the new fluoroscopy rules, as well as helping with special therapies such as Yittrium 90 cases. Conclusion: Medical physicists in both academic and private hospitals are positioned to be more involved and prominent. Diagnostic physicists need to be more proactive to involve themselves in the day to day activities of the radiology department.« less

Pharmacist and Technician Perceptions of Tech-Check-Tech in Community Pharmacy Practice Settings.

PubMed

Frost, Timothy P; Adams, Alex J

2018-04-01

Tech-check-tech (TCT) is a practice model in which pharmacy technicians with advanced training can perform final verification of prescriptions that have been previously reviewed for appropriateness by a pharmacist. Few states have adopted TCT in part because of the common view that this model is controversial among members of the profession. This article aims to summarize the existing research on pharmacist and technician perceptions of community pharmacy-based TCT. A literature review was conducted using MEDLINE (January 1990 to August 2016) and Google Scholar (January 1990 to August 2016) using the terms "tech* and check," "tech-check-tech," "checking technician," and "accuracy checking tech*." Of the 7 studies identified we found general agreement among both pharmacists and technicians that TCT in community pharmacy settings can be safely performed. This agreement persisted in studies of theoretical TCT models and in studies assessing participants in actual community-based TCT models. Pharmacists who had previously worked with a checking technician were generally more favorable toward TCT. Both pharmacists and technicians in community pharmacy settings generally perceived TCT to be safe, in both theoretical surveys and in surveys following actual TCT demonstration projects. These perceptions of safety align well with the actual outcomes achieved from community pharmacy TCT studies.

Progress and Prospect of Physics Research and Education in Taiwan

NASA Astrophysics Data System (ADS)

Raynien Kwo, J.

2010-03-01

Started about two decades ago, the global trend of shifting industrial manufacture power from western developed countries toward developing countries in Asia has in turn become the impetus in building up physical science and research in these areas. A very good example is the remarkable progress of physical research and education in Taiwan, in terms of quantity and quality. The continuous elevation of Taiwan's high education into graduate level plus the government's strong commitment to research and development on a level of 2.62 % GDP have led to an impressive physics program with an annual budget ˜32 million USD from National Science Council in supporting 568 PIs. The investigation scope encompasses high energy and astrophysics, nano and condensed matter, and semiconductor, optoelectronic physics, etc. The former is vigorously conducted via international collaborative efforts of LHC, KEK, ALMA, Pan-STARRS, etc. The latter is driven by vital Taiwan high tech industry mostly semiconductor IC and optoelectronics flourished during this period. The early trend of outflows of BS physics majors to western world for advanced studies has reversed dramatically. Nearly 80% of the BS students continue their MS and PhD degrees in Taiwan, attracted by lucrative job markets of high tech industry. In addition, healthy inflow of high-quality science manpower of well trained PhDs and senior scholars returning to homeland has strengthened the competitiveness. Overall, the physics community in Taiwan is thriving. The annual Physical Society meeting is expanding at a rate of 6%, reaching ˜1800 attendants and 1200 papers, and dedicated to promotions of female physicists and students. The publication quantity of Taiwan in top journals of PRs and PRL is ranked among top 20^th for all fields of physics, and ranked the 6^th in APL. Clearly Taiwan has now emerged as a strong power in applied science, not limited by its population size. Concerted efforts on scientific exchanges are being taken to connect to international societies. The bright outlook of physical science and its vital power in Taiwan is anticipated to provide a stimulus to benefit South East Asia, and have far-reaching impacts on China and worldwide.

Toward healthy prisons: the TECH model and its applications.

PubMed

Ross, Michael W; Jo Harzke, Amy

2012-01-01

This paper aims to explore how the TECH Model (testing for and treating infectious diseases and vaccination; environmental modification to prevent disease transmission; chronic disease identification and treatment; and health maintenance and education) can be used for assessing and achieving healthy prisons. This paper explores the concepts of "health in prison" and "healthy prisons" in the context of recent research and guidance. The paper then considers the TECH Model as an approach to achieving healthy prisons. Under each of the four TECH Model domains are tasks to achieve a healthy prison. For prisons with poor or no resources, each domain contains steps that will improve prison health and move towards a healthy prison for both prisoners and staff. Implementation can thus be "low-TECH" or "high-TECH" depending on the setting and the available resources and the model is specifically designed to provide options for resource-poor as well as resource-rich correctional settings. The TECH Model is a first step in characterizing the components of a healthy prison and the processes to achieve this. This Model could be implemented in all levels of prisons internationally.

Wilderness leadership--on the job.

PubMed

Kanengieter, John; Rajagopal-Durbin, Aparna

2012-04-01

Lessons taught and learned in the challenging, unpredictable environment of a wilderness expedition have direct applications to today's business world. That's according to two directors at the National Outdoor Leadership School, who in this article share five principles for expedition--and career-success. (1) Practice leadership. The fundamental philosophy of NOLS is that leadership can be learned-even by those who don't think they have a natural ability to lead. You just need to practice making decisions, then reflecting on and learning from the outcomes. (2) Lead from everywhere. In an expedition group, or in an organization, you can play four roles, often simultaneously: designated leader, active follower, peer leader, and self-leader. Effective teamwork rests on knowing how and when to step into each role. (3) Behave well Leadership means getting along in a diverse group, cooperating with teammates, effectively resolving conflict, and keeping yourself and others motivated. (4) Keep calm. On expeditions and in business, people often end up scrapping not only Plan A but also Plan B. Leadership involves planning for things you can control, letting go of things you can't, expecting the unexpected, and maintaining composure when unforeseen circumstances arise. (5) Disconnect to connect. The fast-paced, high-tech world of work wreaks havoc on leaders' ability to engage in the careful, strategic thinking required of them. It's important to disconnect from 21st-century distractions and to connect with nature once in a while.

Impact of newer self-monitoring technology and brief phone-based intervention on weight loss: a randomized pilot study

PubMed Central

Ross, Kathryn M.; Wing, Rena R.

2016-01-01

Objective Despite the proliferation of newer self-monitoring technology (e.g., activity monitors and smartphone apps), their impact on weight loss outside of structured in-person behavioral intervention is unknown. Methods A randomized, controlled pilot study was conducted to examine efficacy of self-monitoring technology, with and without phone-based intervention, on 6-month weight loss in adults with overweight and obesity. Eighty participants were randomized to receive standard self-monitoring tools (ST, n=26), technology-based self-monitoring tools (TECH, n=27), or technology-based tools combined with phone-based intervention (TECH+PHONE, n=27). All participants attended one introductory weight loss session and completed assessments at baseline, 3 months, and 6 months. Results Weight loss from baseline to 6 months differed significantly between groups p=.042; there was a trend for TECH+PHONE (−6.4±1.2kg) to lose more weight than ST (−1.3±1.2kg); weight loss in TECH (−4.1±1.4kg) was between ST and TECH+PHONE. Fewer ST (15%) achieved ≥5% weight losses compared to TECH and TECH+PHONE (44%), p=.039. Adherence to self-monitoring caloric intake was higher in TECH+PHONE than TECH or ST, ps<.05. Conclusion These results suggest use of newer self-monitoring technology plus brief phone-based intervention improves adherence and weight loss compared to traditional self-monitoring tools. Further research should determine cost-effectiveness of adding phone-based intervention when providing self-monitoring technology. PMID:27367614

Medical physics in radiotherapy: The importance of preserving clinical responsibilities and expanding the profession's role in research, education, and quality control

PubMed Central

Malicki, Julian

2015-01-01

Medical physicists have long had an integral role in radiotherapy. In recent decades, medical physicists have slowly but surely stepped back from direct clinical responsibilities in planning radiotherapy treatments while medical dosimetrists have assumed more responsibility. In this article, I argue against this gradual withdrawal from routine therapy planning. It is essential that physicists be involved, at least to some extent, in treatment planning and clinical dosimetry for each and every patient; otherwise, physicists can no longer be considered clinical specialists. More importantly, this withdrawal could negatively impact treatment quality and patient safety. Medical physicists must have a sound understanding of human anatomy and physiology in order to be competent partners to radiation oncologists. In addition, they must possess a thorough knowledge of the physics of radiation as it interacts with body tissues, and also understand the limitations of the algorithms used in radiotherapy. Medical physicists should also take the lead in evaluating emerging challenges in quality and safety of radiotherapy. In this sense, the input of physicists in clinical audits and risk assessment is crucial. The way forward is to proactively take the necessary steps to maintain and advance our important role in clinical medicine. PMID:25949219

Zengul, Ferhat D; Weech-Maldonado, Robert; Ozaydin, Bunyamin; Patrician, Patricia A; OʼConnor, Stephen J

U.S. hospitals have been investing in high-technology medical services as a strategy to improve financial performance. Despite the interest in high-tech medical services, there is not much information available about the impact of high-tech services on financial performance. The aim of this study was to examine the impact of high-tech medical services on financial performance of U.S. hospitals by using the resource-based view of the firm as a conceptual framework. Fixed-effects regressions with 2 years lagged independent variables using a longitudinal panel sample of 3,268 hospitals (2005-2010). It was hypothesized that hospitals with rare or large numbers (breadth) of high-tech medical services will experience better financial performance. Fixed effects regression results supported the link between a larger breadth of high-tech services and total margin, but only among not-for-profit hospitals. Both breadth and rareness of high-tech services were associated with high total margin among not-for-profit hospitals. Neither breadth nor rareness of high-tech services was associated with operating margin. Although breadth and rareness of high-tech services resulted in lower expenses per inpatient day among not-for-profit hospitals, these lower costs were offset by lower revenues per inpatient day. Enhancing the breadth of high-tech services may be a legitimate organizational strategy to improve financial performance, especially among not-for-profit hospitals. Hospitals may experience increased productivity and efficiency, and therefore lower inpatient operating costs, as a result of newer technologies. However, the negative impact on operating revenue should caution hospital administrators about revenue reducing features of these technologies, which may be related to the payer mix that these technologies may attract. Therefore, managers should consider both the cost and revenue implications of these technologies.

With the profound changes currently occurring in medicine, the role of the medical physicist cannot stagnate, but must evolve to meet the challenges and opportunities that are presented. Medical physicists must understand these changes and establish themselves not only as relevant but as leaders in this new environment. We must increase our presence in clinical settings such as tumor boards, patient rounds, and the development of new diagnosis, imaging, and treatment techniques. By establishing ourselves as competent scientists, we can and must participate in the development of technologies through research, teaching, and clinical implementation. As medical physicists we must definemore » our roles and value to our physician colleagues, patients, referring physicians, and senior administrators. We cannot afford to be viewed solely as quality assurance technologists, but need to move forward in step with medical and practice advances, becoming recognized as having a leadership role in providing quality research, technological development, and quality patient care. In this session, four leaders in medical research and healthcare will discuss their observations on how medical physicists have contributed to advancements in healthcare and opportunities to continue leadership in providing quality medicine through the applications of physics to research, education, and clinical practice. Learning Objectives: Understand the changes in the healthcare environment and how medical physicists can contribute to improving patient care. Learn how medical physicists are currently leading research efforts to improve clinical imaging and diagnosis. Understand the role of medical physicists in developing new technology and leading its translation into clinical care.« less

Biodegradation of tech-hexachlorocyclohexane in a upflow anaerobic sludge blanket (UASB) reactor.

PubMed

Bhat, Praveena; Kumar, M Suresh; Mudliar, Sandeep N; Chakrabarti, T

2006-04-01

Biodegradability of technical grade hexachlorocyclohexane (tech-HCH) was studied in an upflow anaerobic sludge blanket reactor (UASB) under continuous mode of operation in concentration range of 100-200 mg/l and constant HRT of 48 h. At steady state operation more than 85% removal of tech-HCH (upto 175 mg/l concentration) and complete disappearance of beta-HCH was observed. Kinetic constants in terms of maximum specific tech-HCH utilization rate (k) and half saturation velocity constant (K(L)) were found to be 11.88 mg/g/day and 8.11 mg/g/day, respectively. The tech-HCH degrading seed preparation, UASB reactor startup and degradation in continuous mode of operation of the reactor is presented in this paper.

While physics is an investigation of the world around us, physicists and the practice of physics research exist within the world in combination with aspects of society. This means that physicists and physics research are subject to federal policies and regulations that affect how physics is done. Who decides or influences those policies? Who speaks up on our behalf? Who investigates policy issues from a physics point of view? As physicists, we can lend our expertise and insight in order to ensure a fruitful future for physics and science more broadly, whether it be an occasional policy action taken or a career in science policy and government relations. In this talk I'll share the story of my transition from academia to a policy-focused career at APS and what it means to be a physicist on the frontlines of government relations.

Physics and nuclear power

NASA Astrophysics Data System (ADS)

Buttery, N. E.

2008-03-01

Nuclear power owes its origin to physicists. Fission was demonstrated by physicists and chemists and the first nuclear reactor project was led by physicists. However as nuclear power was harnessed to produce electricity the role of the engineer became stronger. Modern nuclear power reactors bring together the skills of physicists, chemists, chemical engineers, electrical engineers, mechanical engineers and civil engineers. The paper illustrates this by considering the Sizewell B project and the role played by physicists in this. This covers not only the roles in design and analysis but in problem solving during the commissioning of first of a kind plant. Looking forward to the challenges to provide sustainable and environmentally acceptable energy sources for the future illustrates the need for a continuing synergy between physics and engineering. This will be discussed in the context of the challenges posed by Generation IV reactors.

Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to compare intakes of fruits, vegetables, fruit juice, sweetened beverages, candy, ice cream, and bakery products using TECH with intakes acquired by 24 h dietary recalls. Participants were 39 healthy, Swedish children (5.5 ± 0.5 years) within the ongoing Mobile-based Intervention Intended to Stop Obesity in Preschoolers (MINISTOP) obesity prevention trial. Energy and food intakes were assessed during four days using TECH and 24 h telephone dietary recalls. Mean EI (TECH) was not statistically different from TEE (DLW) (5820 ± 820 kJ/24 h and 6040 ± 680 kJ/24 h, respectively). No significant differences in the average food intakes using TECH and 24 h dietary recalls were found. All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665-0.896, p < 0.001). In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

A survey was created by NRG to assess a medical physicists' percent full time equivalent (FTE) contribution to multi-institutional clinical trials. A 2012 American Society for Radiation Oncology report, "Safety Is No Accident," quantified medical physics staffing contributions in FTE factors for clinical departments. No quantification of FTE effort associated with clinical trials was included. To address this lack of information, the NRG Medical Physics Subcommittee decided to obtain manpower data from the medical physics community to quantify the amount of time medical physicists spent supporting clinical trials. A survey, consisting of 16 questions, was designed to obtain information regarding physicists' time spent supporting clinical trials. The survey was distributed to medical physicists at 1996 radiation therapy institutions included on the membership rosters of the 5 National Clinical Trials Network clinical trial groups. Of the 451 institutions who responded, 50% (226) reported currently participating in radiation therapy trials. On average, the designated physicist at each institution spent 2.4 hours (standard deviation [SD], 5.5) per week supervising or interacting with clinical trial staff. On average, 1.2 hours (SD, 3.1), 1.8 hours (SD, 3.9), and 0.6 hours (SD, 1.1) per week were spent on trial patient simulations, treatment plan reviews, and maintaining a Digital Imaging and Communications in Medicine server, respectively. For all trial credentialing activities, physicists spent an average of 32 hours (SD, 57.2) yearly. Reading protocols and supporting dosimetrists, clinicians, and therapists took an average of 2.1 hours (SD, 3.4) per week. Physicists also attended clinical trial meetings, on average, 1.2 hours (SD, 1.9) per month. On average, physicist spent a nontrivial total of 9 hours per week (0.21 FTE) supporting an average of 10 active clinical trials. This time commitment indicates the complexity of radiation therapy clinical trials and should be taken into account when staffing radiation therapy institutions. Copyright © 2018 Elsevier Inc.

Changes in the issue of women in physics in Lithuanian in the three years since the 3rd IUPAP International Conference on Women in Physics are discussed on the basis of statistics as well as an exploratory study recently conducted among women physicists. The situation has changed slowly since 2008. However, the study shows that women physicists more clearly understand the inequities and the need for changes, including an active European Union mainstreaming policy targeted to ensure gender equality in the sciences, which gives hope for accelerating changes. Continued plans for improving women physicists' situation in Lithuania are discussed.

Student reasoning about ratio and proportion in introductory physics

NASA Astrophysics Data System (ADS)

Boudreaux, Andrew

2012-02-01

To many students, introductory physics must seem a fast-moving parade of abstract and somewhat mysterious quantities. Most such quantities are rooted in proportional reasoning. Using ratio, physicists construct the force experienced by a unit charge, and attach the name electric field, or characterize a motion with the velocity change that occurs in a unit time. While physicists reason about these ratios without conscious effort, students tend to resort to memorized algorithms, and at times struggle to match the appropriate algorithm to the situation encountered. Although the term ``proportional reasoning'' is prevalent, skill in reasoning with these ratio quantities is neither acquired nor applied as a single cognitive entity. Expert ability seems to be characterized by the intentional use of a variety of components, or elements of proportional reasoning, by a fluency in shifting from one component to another, and by a skill in selecting from among these components. Based on this perspective, it is natural to expect students to develop proportional reasoning ability in fits and starts as various facets are acquired and integrated into existing understandings. In an ongoing collaboration between Western Washington University, New Mexico State University, and Rutgers, we are attempting to map the rich cognitive terrain of proportional reasoning, and to use our findings to guide the design of instruction that develops fluency. This talk will present a provisional set of proportional reasoning components, along with research tasks that have been developed to measure student ability along these components. Student responses will be presented as evidence of specific modes of thinking. The talk will conclude with a brief outline of our approach to improving student understanding.

Flexibility and innovation at creating shapes, adapting processes, and modifying materials characterize composites materials, a "high-tech" industry. However, the absence of standard manufacturing processes and the selection of materials with defined properties hinder the configuration of the composites materials supply chain. An interesting alternative for a "high-tech" industry such as composite materials would be to review supply chain lessons and practices in "low-tech" industries such as food. The main motivation of this study is to identify lessons and practices that comprise innovations in the supply chain of a firm in a perceived "low-tech" industry that can be used to provide guidelines in the design of the supply chain of a "high-tech" industry, in this case composite materials. This work uses the case study/site visit with analogy methodology to collect data from a Spanish leading producer of fresh fruit juice which is sold in major European markets and makes use of a cold chain. The study highlights supply base management and visibility/traceability as two elements of the supply chain in a "low-tech" industry that can provide guidelines that can be used in the configuration of the supply chain of the composite materials industry.

Chinese physicists educated in Germany and America: Their scientific contributions and their impact on China's higher education

NASA Astrophysics Data System (ADS)

Qu, Jing Cheng

1998-11-01

This dissertation records the historical paths of Chinese physicists educated in Germany and America, explores their representative achievements in modern physics that have not been recognized by Chinese scholars, and provides sociological analyses of their contributions to China's higher education. We have found that Chinese students of physics in Germany and America were not passive recipients of Western science, but active contributors. They were also crucial contributors to science education and important scientific projects upon their return to China. Chapter One briefly describes physics knowledge in ancient China and introduces the transplantation of modern science and technology to China. Three distinct historical periods have been identified. In Chapter Two and Chapter Three, 30 Chinese physicists educated in Germany and 89 in America have been investigated. This research analyzes the significant achievements of these physicists. It also examines the political changes, the social background, and other factors impacting on their studies in the two countries. The selected cases in the two chapters are Li Fo-ki, Chinese physics students in Berlin, Werner Heisenberg and his Chinese students, Max Born and his Chinese students, Robert Millikan and Chinese physicists, the first two Chinese physicists from Harvard, and the Science Society of China. Chapter Four explores the geographical distribution, education and careers, return and expatriation, and the social influence exerted by these Chinese physicists. Statistical compilation and quantitative analyses comprise the basic methodology. In terms of two periods and two generations, this dissertation explores the physicists' contributions to the development of modern science in China and to education in China. Significant cases from Beijing University, Qinghua University, and Yanjing University are analyzed. The last chapter, Chapter Five, concludes that some of the achievements of these Chinese physicists were critical steps in modern physics even though China remained domestically rather weak in the development of modern science. Returning to China, most of them became pioneers and active contributors to modern science and to higher education in China. They comprised the majority of the physics community of China and played a leading role in the formation of modern science in China. After 1949, China continued to benefit from the contributions of these physicists. China independently constructed an atomic bomb in 1964 and a hydrogen bomb in 1967. In 1970, China successfully launched a man-made satellite. The Chinese physicists trained in Western countries constituted the main research force behind these projects.

The Status of African American Physicists within the DOE Laboratories

NASA Astrophysics Data System (ADS)

Jackson, Keith

2005-03-01

In May 2002 there was a backpage article published in American Physical Society Newsletter by the President of the National Society of Black Physicists (NSBP). This article showed that of the 3372 professional physicists employed at the DOE national labs, only 11 are African American, which on a percentage basis is 4 times less than the total availability of Ph.D. African American physicists in the labor force. NSBP want to provide an update of the interaction between National Society of Black Physicists (NSBP) and the department of Energy in particular the Office of Science on the issue of employment of African American Physicists in scientific and technical. You might ask the following question: Why should the current generation of African American Physicists be concerned about their underepresentation on the scientific staffs of the DOE National Laboratories? The answer to this question may vary from person to person, but I would like to propose the following: The National Laboratories are the largest providers of career opportunities in Physics in the United States. There is a general view in the community; African Americans are not getting a return on their national investment in the DOE National Labs. Failure to engage with HBCU’s through their user facilities causes a training or skills deficit when it comes to preparing students to participate at the forefront of physics research. By rebuffing interactions with HBCU¹s, as many the laboratories have done, the national laboratories are in effect refusing to transfer scientific knowledge to the stakeholders in the African American community. The update will contain some additional information about NSBP proposals to solve the problem of underepresentation of African American and Hispanic physicists within the National Laboratories and how the Office of Science has response these proposals.

FIAP Forum on Entrepreneurship in Physics

NASA Astrophysics Data System (ADS)

2015-03-01

With the changes in science as globalization has taken root, the future role of physicists becoming a part of the industrial physics community is more imperative. When 80% of graduating physicists will not be employed in academic positions, and 50% of all jobs for these physicists will be industrial sector, the importance of bringing our next generation of scientists up to speed on industrial applications is becoming much more important with the rapid, world-wide development of technology. FIAP is initiating a forum on entrepreneurship as a major role for the next generation of scientists. As physicists are problem solvers and the entrepreneurial experience is all about problem solving: whether involving technology, building a team, or financing a business. This forum seeks to link successful entrepreneurial physicists with the upcoming generation, through the dissemination of their global expertise and experience. The forum will consist of a panel discussion and then be open to question and answers from the audience.

The role of philosophy in the conceptual development of quantum physics

NASA Astrophysics Data System (ADS)

Diamond, Ethel

Making a distinction between the context of discovery and the context of justification, I examine the relationship between philosophy and the discovery of quantum physics. I do this by focusing on four of the most important contributors to quantum theory: Albert Einstein, Werner Heisenberg, Erwin Schrodinger and Niels Bohr. Looking to the period immediately preceding the era in which quantum physics was developed, I first explore the scientific writings of Hermann von Helmholtz, Ernst Mach, Heinrich Hertz and Ludwig Boltzmann. In doing so, I uncover the integral role classic philosophy played in the scientific investigations of nineteenth-century German and Austrian physicists. After establishing the cultural link between scientific writing and philosophic training at that time and place in history, I investigate the formative philosophic influences on Einstein, Heisenberg, Schrodinger and Bohr. By a close examination of some of their most important scientific papers, this dissertation reveals the way in which these early twentieth-century scientists continued an important nineteenth-century European tradition of integrating philosophic thought in their scientific creative thinking.

Shoichi Sakata: His Life and Physics ---Collections of Materials in Sakata Memorial Archival Library---

NASA Astrophysics Data System (ADS)

Tanabashi, M.

Shoichi Sakata and his Nagoya School made a lot of important achievements at the predawn of the particle physics revolution. The ``two-meson'' theory (introduction of the second generation leptons), the ``C-meson theory'' (a theory which inspired Tomonaga's renormalization theory), the ``Sakata model'' (a precursor to the quark model), and the ``Maki-Nakagawa-Sakata'' theory on the neutrino mixings are among them. These outputs are now regarded as essential ingredients in modern particle physics. Sakata also took his leadership in setting up democratic administration system in his theoretical particle physics group (E-ken). It was this democratic atmosphere in which many excellent physicists were brought up as Sakata's diciples. In this talk, I introduce Sakata and his achievements in physics, showing various materials archived in the Sakata Memorial Archival Library (SMAL), an archival repository of primary material showing Sakata's activities. These SMAL documents vividly show Sakata's way of thinking in his approach to the new physics.

Long-Distance Free Fall

One of the goals of physics education is to instill a sense of wonder in our students. We hope our natural curiosity will rub off on them and that they will apply the critical thinking skills we teach them to other aspects of their lives outside the classroom. As an example of this, consider the situation described in Milton's epic poem ``Paradise Lost''. Milton wrote that when the devil was cast out of heaven, he fell for nine days before landing in hell. In Milton's universe, hell is a separate place from Earth, but many people place hell at the center of the Earth. Based on these ideas, we can apply Newton's laws of motion to calculate the distance from heaven to Earth. This exercise is an example of the kind of intellectual exercise a physicist (or a physics student) might carry out when confronted with such information. We apply the basic principles of physics to a situation described in work of literature while making no attempt to validate or refute any philosophy, theology or ideology.

Generally objective measurement of human temperature and reading ability: some corollaries.

PubMed

Stenner, A Jackson; Stone, Mark

2010-01-01

We argue that a goal of measurement is general objectivity: point estimates of a person's measure (height, temperature, and reader ability) should be independent of the instrument and independent of the sample in which the person happens to find herself. In contrast, Rasch's concept of specific objectivity requires only differences (i.e., comparisons) between person measures to be independent of the instrument. We present a canonical case in which there is no overlap between instruments and persons: each person is measured by a unique instrument. We then show what is required to estimate measures in this degenerate case. The canonical case encourages a simplification and reconceptualization of validity and reliability. Not surprisingly, this reconceptualization looks a lot like the way physicists and chemometricians think about validity and measurement error. We animate this presentation with a technology that blurs the distinction between instruction, assessment, and generally objective measurement of reader ability. We encourage adaptation of this model to health outcomes measurement.

The manifold definitions of time.

PubMed

Oestreicher, Christian

2012-12-01

We are unable, using our five senses, to feel time, nor, using our intelligence, to define it, because we stand inexorably within time. We achieve a representation of time through evaluation of changes in ourselves and in our environment. This is made possible by memory functions. What if time only existed as a construct in our minds, and what if the absence of this construct made our mode of thinking uncomfortable to us? If our two major tools for constructing our world, feeling and reasoning, are of little help, then the study of time, ie, chronology, might exist as a list of scientific hypotheses, and remain, to some extent, a philosophical question--an enigma that has been approached by thinkers for more than two millenia. In this review, various fields of knowledge are discussed in relation to time, from philosophy and physics to psychology and biology. We discuss the differences between Chronos and Tempus, respectively the time of physicists and that of psychologists.

Understanding the world -- This aim drives humankind since the beginning of conscious thinking. Especially the nature of matter has been of major interest. Nowadays, we have a complex image of the constitution of matter. Atoms consist of electrons and nucleons. But even nucleons are not elementary. Their basic constituents are called quarks. Physicists developed a model describing the elementary components of matter as well as the forces between them: the standard model of elementary particle physics. The substructure of matter is only visible in scattering experiments. In high energy physics, these experiments are done at particle accelerators. The world'smore » highest energetic collider, the Tevatron, is hosted by the Fermi National Accelerator Laboratory (FNAL), also called Fermilab, in the vicinity of Chicago.

Multi-Valued Logic, Neutrosophy, and Schrödinger Equation

NASA Astrophysics Data System (ADS)

Smarandache, Florentin; Christianto, Victor

2017-04-01

Discussing some paradoxes in Quantum Mechanics from the viewpoint of Multi-Valued-logic pioneered by Lukasiewicz, and the recent concept Neutrosophic Logic. Essentially, this new concept offers new insights on the idea of `identity', which too often it has been accepted as given. Neutrosophy itself was developed in attempt to generalize Fuzzy-Logic introduced by L. Zadeh. The discussion is motivated by observation that despite almost eight decades, there is indication that some of those paradoxes known in Quantum Physics are not yet solved. In our knowledge, this is because the solution of those paradoxes requires re-examination of the foundations of logic itself, in particular on the notion of identity and multi-valuedness of entity. The discussion is also intended for young physicist fellows who think that somewhere there should be a `complete' explanation of these paradoxes in Quantum Mechanics. If this it doesn't answer all of their questions, it is our hope that at least it offers a new alternative viewpoint for these old questions.

Life as an Ex-Physicist on Wall Street

NASA Astrophysics Data System (ADS)

Derman, Emanuel

2001-06-01

Financial theory looks deceptively like physics because of the techniques it uses. But physics models deal with the relatively unchanging parameters of the external world; in contrast, the parameters of financial theory are people's current estimates of, and sentiments about, future behavior. Life as a Ph.D. on Wall St is therefore very different from the way most people in academic life imagine it to be. For most of us, most of the time, it involves neither finding miraculous and previously undiscovered arbitrages, nor doing boring mindless programming. Instead, it demands an interdisciplinary mix of inventive computation, applied mathematics, financial understanding, self-education and educating others, applied in a hectic environment, to help build and maintain a business. Financial modeling as a practitioner means suffering many interruptions when you want to think quietly, and making many pragmatic compromises dictated by constraints on time and resources. It also means a stimulating and lively environment, using your imagination, avoiding complexity, and always trying to bridge the gap between analysis and intuition (yours and others).

What Physicist Mean By The Equals Sign In Undergraduate Education

NASA Astrophysics Data System (ADS)

Zohrabi Alaee, Dina; Kornick, Kellianne; Sayre, Eleanor C.; Franklin, Scott V.

2017-01-01

Mathematical concepts and tools have an important role in physics. Faculties want students to think critically about mathematics and the underlying fundamental concepts, rather than simply memorizing a series of equations and answers. The equals sign - ubiquitous in problem solving - carries different conceptual meaning depending on how it is used; this meaning is deeply tied to cultural practices in problem solving in physics. We use symbolic forms to investigate the conceptual and cultural meanings of the equals sign across physics contexts. We built and validated a rubric to classify the ways that physics students use the equals sign in their written work. Our categories are causality, assignments, definitional, balancing, and just math. We analyze students' use of the equals sign in their written homework and exam solutions in an upper-division electrostatics course. We correlate the kinds of equal signs within problem solutions with the difficulty of the problem. We compare they ways students use the equals sign to their course lectures and textbook.

Does the high–tech industry consistently reduce CO{sub 2} emissions? Results from nonparametric additive regression model

DOE Office of Scientific and Technical Information (OSTI.GOV)

Xu, Bin; Research Center of Applied Statistics, Jiangxi University of Finance and Economics, Nanchang, Jiangxi 330013; Lin, Boqiang, E-mail: bqlin@xmu.edu.cn

China is currently the world's largest carbon dioxide (CO{sub 2}) emitter. Moreover, total energy consumption and CO{sub 2} emissions in China will continue to increase due to the rapid growth of industrialization and urbanization. Therefore, vigorously developing the high–tech industry becomes an inevitable choice to reduce CO{sub 2} emissions at the moment or in the future. However, ignoring the existing nonlinear links between economic variables, most scholars use traditional linear models to explore the impact of the high–tech industry on CO{sub 2} emissions from an aggregate perspective. Few studies have focused on nonlinear relationships and regional differences in China. Basedmore » on panel data of 1998–2014, this study uses the nonparametric additive regression model to explore the nonlinear effect of the high–tech industry from a regional perspective. The estimated results show that the residual sum of squares (SSR) of the nonparametric additive regression model in the eastern, central and western regions are 0.693, 0.054 and 0.085 respectively, which are much less those that of the traditional linear regression model (3.158, 4.227 and 7.196). This verifies that the nonparametric additive regression model has a better fitting effect. Specifically, the high–tech industry produces an inverted “U–shaped” nonlinear impact on CO{sub 2} emissions in the eastern region, but a positive “U–shaped” nonlinear effect in the central and western regions. Therefore, the nonlinear impact of the high–tech industry on CO{sub 2} emissions in the three regions should be given adequate attention in developing effective abatement policies. - Highlights: • The nonlinear effect of the high–tech industry on CO{sub 2} emissions was investigated. • The high–tech industry yields an inverted “U–shaped” effect in the eastern region. • The high–tech industry has a positive “U–shaped” nonlinear effect in other regions. • The linear impact of the high–tech industry in the eastern region is the strongest.« less

Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to compare intakes of fruits, vegetables, fruit juice, sweetened beverages, candy, ice cream, and bakery products using TECH with intakes acquired by 24 h dietary recalls. Participants were 39 healthy, Swedish children (5.5 ± 0.5 years) within the ongoing Mobile-based Intervention Intended to Stop Obesity in Preschoolers (MINISTOP) obesity prevention trial. Energy and food intakes were assessed during four days using TECH and 24 h telephone dietary recalls. Mean EI (TECH) was not statistically different from TEE (DLW) (5820 ± 820 kJ/24 h and 6040 ± 680kJ/24 h, respectively). No significant differences in the average food intakes using TECH and 24 h dietary recalls were found. All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665–0.896, p < 0.001). In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

Developing Technology Products - A Physicist's Perspective

NASA Astrophysics Data System (ADS)

Burka, Michael

2014-03-01

There are many physicists working in the industrial sector. We rarely have the word physicist in our job title; we are far more commonly called engineers or scientists. But, we are physicists, and we succeed because our training in physics has given us the habits of mind and the technical skills that one needs to solve complex technical challenges. This talk will explore the transition from physics research to technology product development using examples from my own career, first as a postdoctoral fellow and research scientist on the LIGO project, and then developing products in the spectroscopy, telecommunications, and medical device industries. Approaches to identifying and pursuing opportunities in industry will be discussed.

Project Georgia High School/High Tech

NASA Technical Reports Server (NTRS)

2000-01-01

The High School/High Tech initiative of the President's Committee on Employment of Disabilities, Georgia's application of the collaborative "Georgia Model" and NASA's commitment of funding have shown that opportunities for High School/High Tech students are unlimited. In Georgia, the partnership approach to meeting the needs of this program has opened doors previously closed. As the program grows and develops, reflecting the needs of our students and the marketplace, more opportunities will be available. Our collaboratives are there to provide these opportunities and meet the challenge of matching our students with appropriate education and career goals. Summing up the activities and outcomes of Project Georgia High School/High Tech is not difficult. Significant outcomes have already occurred in the Savannah area as a result of NASA's grant. The support of NASA has enabled Georgia Committee to "grow" High School/High Tech throughout the region-and, by example, the state. The success of the Columbus pilot project has fostered the proliferation of projects, resulting in more than 30 Georgia High School High Tech programs-with eight in the Savannah area.

A Geoscience Workforce Model for Non-Geoscience and Non-Traditional STEM Students

Liou-Mark, J.; Blake, R.; Norouzi, H.; Vladutescu, D. V.; Yuen-Lau, L.

2016-12-01

The Summit on the Future of Geoscience Undergraduate Education has recently identified key professional skills, competencies, and conceptual understanding necessary in the development of undergraduate geoscience students (American Geosciences Institute, 2015). Through a comprehensive study involving a diverse range of the geoscience academic and employer community, the following professional scientist skills were rated highly important: 1) critical thinking/problem solving skills; 2) effective communication; 3) ability to access and integrate information; 4) strong quantitative skills; and 5) ability to work in interdisciplinary/cross cultural teams. Based on the findings of the study above, the New York City College of Technology (City Tech) has created a one-year intensive training program that focusses on the development of technical and non-technical geoscience skills for non-geoscience, non-traditional STEM students. Although City Tech does not offer geoscience degrees, the primary goal of the program is to create an unconventional pathway for under-represented minority STEM students to enter, participate, and compete in the geoscience workforce. The selected cohort of STEM students engage in year-round activities that include a geoscience course, enrichment training workshops, networking sessions, leadership development, research experiences, and summer internships at federal, local, and private geoscience facilities. These carefully designed programmatic elements provide both the geoscience knowledge and the non-technical professional skills that are essential for the geoscience workforce. Moreover, by executing this alternate, robust geoscience workforce model that attracts and prepares underrepresented minorities for geoscience careers, this unique pathway opens another corridor that helps to ameliorate the dire plight of the geoscience workforce shortage. This project is supported by NSF IUSE GEOPATH Grant # 1540721.

Lecture to inquiry: The transformation of a tech prep biology teacher

NASA Astrophysics Data System (ADS)

Haskell, Deborah Harris

As teachers implement the National Science Education Standards (NRC, 1996) many have to reform the instructional methods they have used throughout their careers. This case study examines the transformation of Laurie, a 20-year teacher, during her first year of change from a "traditional" textbook/lecture style of teaching to a facilitator of an inquiry-based classroom. Implementing change requires not only pedagogical expertise, but also the belief that the modifications can be made and that the outcomes are significant. Using Bandura's social cognitive theory as a framework, changes in Laurie's self-efficacy, outcome expectancy, and motivation are followed throughout the transition. During her first year of change, Laurie used worksheets, small group activities, and guided inquiry activities, all strategies in which she had high self-efficacy and experienced positive student outcomes. She rarely used class forums, authentic assessment, and formative assessment. Factors that influenced her change were experiential professional development opportunities that allowed her to practice inquiry-based techniques, a change in her teaching environment from college prep chemistry to tech prep biology, autonomy regarding classroom decisions, and reflective decision making as she learned through experience. Using a standards-based biology textbook increased her self-efficacy toward using inquiry-based practices. The textbook format of embedding text in activities rather than adding activities to the text resulted in an increase of the number and frequency of activities done. Facilitating the textbook's Guided Inquiries and Extended Inquiries helped Laurie gain experience with inquiry-based methods. She also realized that when building from the students' concrete experiences, her students were able to attain higher-level thinking skills. The study revealed six factors contributing to Laurie's change process: (a) experiential professional development, (b) motivation for change, (c) classroom autonomy, (d) growth through reflective practice, (e) curricular support, and (f) time.

Is the Writing on the Wall for Tabletops?

NASA Astrophysics Data System (ADS)

Pantidi, Nadia; Rogers, Yvonne; Robinson, Hugh

We describe an ethnographic study that explores how low tech and new tech surfaces support participation and collaboration during a workshop breakout session. The low tech surfaces were post-it notes and large sheets of paper. The new tech surfaces were writeable walls and a multi-touch tabletop. Four groups used the different surfaces during three phases: i) brief presentation of position papers and discussion of themes, ii) the creation of a group presentation and iii) a report back session. Participation and collaboration varied depending on the physical, technological and social factors at play when using the different surfaces. We discuss why this is the case, noting how new shareable surfaces may need to be constrained to invite participation in ways that are simply taken for granted because of their familiarity when using low tech materials.

Physicists for Human Rights in the Former Soviet Union

NASA Astrophysics Data System (ADS)

Chernyak, Yuri

2005-03-01

In his 1940 paper `Freedom and Science' Albert Einstein emphasized that ``intellectual independence is a primary necessity for the scientific inquirer'' and that ``political liberty is also extraordinarily important for his work.'' Raised in the tradition of intellectual independence and dedicated to the scientific truth, physicists were among the first to stand up for freedom in the USSR. It was no coincidence that the founders of the first independent Human Rights Committee (1970) were physicists: Andrei Sakharov, Valery Chalidze and Andrei Tverdokhlebov. In 1973 a physicist, Alexander Voronel, founded a Moscow Sunday (refusenik) Seminar -- the first openly independent scientific body in the history of the USSR. In 1976 physicists Andrei Sakharov, Yuri Orlov and a mathematician Natan Sharansky were the leading force in founding the famous Moscow Helsinki Human Rights Watch group. This talk briefly describes the special position of physicists (often viewed as Einstein's colleagues) in Soviet society, as well as their unique role in the struggle for human rights. It describes in some detail the Moscow Sunday Seminar, and extensions thereof such as International Conferences, the Computer School and the Computer Database of Refuseniks. The Soviet government considered such truly independent organizations as a challenge to Soviet authority and tried to destroy them. The Seminar's success and its very existence owed much to the support of Western scientific organizations, who persuaded their members to attend the Seminar and visit scientist-refuseniks. The human rights struggle led by physicists contributed substantially to the demise of the Soviet system.

Core curriculum for medical physicists in radiology. Recommendations from an EFOMP/ESR working group.

Some years ago it was decided that a European curriculum should be developed for medical physicists professionally engaged in the support of clinical diagnostic imaging departments. With this in mind, EFOMP (European Federation of Organisations for Medical Physics) in association with ESR (European Society of Radiology) nominated an expert working group. This curriculum is now to hand. The curriculum is intended to promote best patient care in radiology departments through the harmonization of education and training of medical physicists to a high standard in diagnostic radiology. It is recommended that a medical physicist working in a radiology department should have an advanced level of professional expertise in X-ray imaging, and additionally, depending on local availability, should acquire knowledge and competencies in overseeing ultrasound imaging, nuclear medicine, and MRI technology. By demonstrating training to a standardized curriculum, medical physicists throughout Europe will enhance their mobility, while maintaining local high standards of medical physics expertise. This document also provides the basis for improved implementation of articles in the European medical exposure directives related to the medical physics expert. The curriculum is divided into three main sections: The first deals with general competencies in the principles of medical physics. The second section describes specific knowledge and skills required for a medical physicist (medical physics expert) to operate clinically in a department of diagnostic radiology. The final section outlines research skills that are also considered to be necessary and appropriate competencies in a career as medical physicist.

Objectives To determine the effects on weight loss of three abbreviated behavioral weight loss interventions with and without coaching and mobile technology. Methods Randomized controlled efficacy study of three six-month weight loss treatments delivered to 96 adults with obesity: 1) self-guided [SELF], 2) standard [STND], or 3) technology-supported [TECH]. STND and TECH received 8 in-person group treatment sessions. SELF and STND used paper diaries to self-monitor diet, activity, and weight; TECH used a smartphone application with social networking features and wireless accelerometer. Results Weight loss was greater for TECH and STND than SELF at 6 months [−5.7kg (95% CI: −7.2, −4.1) vs. −2.7kg (95% CI: −5.1, −0.3), p<.05]), but not 12 months. TECH and STND did not differ except that more STND (59%) than TECH (34%) achieved ≥5% weight loss at 6 months (P < 0.05). Self-monitoring adherence was greater in TECH than STND (P <0.001), greater in both interventions than SELF (P <0.001), and covaried with weight loss (r(84) = 0.36 − 0.51, P<.001). Conclusions Abbreviated behavioral counseling can produce clinically meaningful weight loss regardless of whether self-monitoring is performed on paper or smartphone, but long-term superiority over standard of care self-guided treatment is challenging to maintain.

Teaching about volcano deformation and how scientists study these processes using GNSS/GPS may present some challenge since the volcanoes and/or GNSS/GPS equipment are not quite accessible to most teachers. Educators and curriculum materials specialists have developed and shared a number of activities and demonstrations to help students visualize volcanic processes and ways scientist use GNSS/GPS in their research. From resources provided by MEDL (the Modeling and Educational Demonstrations Laboratory) in the Department of Geosciences at Virginia Tech, we combined multiple materials and techniques from these previous works to produce a hands-on physical analog model from which students can learn about GNSS/GPS studies of volcano deformation. The model functions as both a qualitative and quantitative learning tool with good analogical affordances. In our presentation, we will describe multiple ways of teaching with the model, what kinds of materials can be used to build it, and ways we think the model could be enhanced with the addition of Vernier sensors for data collection.

WE-G-204-00: Post-Graduate Training of the Next Generation of Academic Medical Physicists

DOE Office of Scientific and Technical Information (OSTI.GOV)

NONE

While many indicators for academic medical physics are distressing – jobs are tight, demands on clinical time are high (and getting worse) and national funding has been flat for several years (meaning less money in reality) the present is perhaps one of the most exciting times in cancer research history, and medical physicists have an opportunity to make a difference. Many of us predict the impact of medical physics on cancer research over the next decade to be more significant than ever. Why is that? First, medical imaging is used for every cancer patient in developed countries. Every improvement inmore » the acquisition, processing or analysis of radiological images has the potential to impact patients. The use of radiation therapy is at an all-time high – and virtually cannot be performed without medical physics. Many of the advances in both biomedical imaging and radiation oncology are the result of the hard work of academic medical physicists who are thinking of the next generation of technologies that will be used against cancer or an even broader spectrum of diseases. A career in academic medical physics is demanding, particularly for those with clinical responsibilities. As the demands for justification of their clinical effort become increasingly metricized, the ability to do “unfunded research” will become even more difficult. This means that many will have to generate external salary support to justify their efforts in research and development. This comes at a time when funding for research is compressed and harder to obtain. Generally speaking, if you are not contributing 50% or more of your effort to research, you are competing at a disadvantage and it is very unlikely you will get an NIH/NCI/NIBIB grant. Furthermore, in the ongoing effort to improve patient care and safety, we have developed credentialing pathways that now require at least two-years of residency training. This full-time clinical training creates a gap in the research trajectory of graduate students who aspire to academic positions with an expectation for extramural funding. To address this, several residency programs have created hybrid programs where the two-years of clinical training is combined with one or two years of research effort to allow candidates to further establish an academic identity and to ensure adequate academic productivity to compete for a beginning faculty position. In conclusion, while the path to a successful career in academic medical physics is steep and sometimes hard to follow, reaching the apex is worth the journey. Different paths to a career in medical physics are available, you just have to decide which one is right for you. If improving cancer care is your goal as a physicist, then academic medical physics is the job for you!.« less

TCASE v1.0 implements a data import solution that was achievable within the project scope, while still providing the basis for a long-term ability to keep TCASE in sync with TechPort. Conclusion: TCASE data quantity is adequate and the established data pipeline will enable future growth. Data quality is now highly dependent the quality of data in TechPort. Recommendation: Technology development organizations within NASA should continue to work closely with project/program data tracking and archiving efforts (e.g. TechPort) to ensure that the right data is being captured at the appropriate quality level. TCASE would greatly benefit, for example, if project cost/budget information was included in TechPort in the future.

2015-01-01

Two philosophical ideas motivate this paper. The first is an answer to the question of what is an appropriate activity for a physicist. My answer is that an appropriate activity is anything where the tools of a physicist enable him or her to make a contribution to the solution of a significant problem. This may be obvious in areas that overlap…

``Physics and the girly girl—there is a contradiction somewhere'': doctoral students' positioning around discourses of gender and competence in physics

NASA Astrophysics Data System (ADS)

Gonsalves, Allison J.

2014-06-01

Doctoral physics students have stories about what kinds of actions, behaviours and ways of doing physics allow individuals to be recognized as physicists. Viewing a physics department as a case study, and individual participants as embedded cases, this study used a sociocultural approach to examine the ways doctoral students construct these stories about becoming physicists. Through observations, photo-elicitation, and life history interviews, eleven men and women shared stories about their experiences with physics, and the contexts that have enabled or constrained their trajectories into doctoral physics. The results of this study revealed the salience of recognition in the constitution of physicist identities; but how recognition was achieved often entailed the reproduction or reworking of persistent discourses of gender norms. Various interchangeable forms of competence (technical, analytical, and academic) emerged as assets that can be used to achieve recognition in this physics community. However, competence was not the only means by which one might be recognized as a physicist. Contributing to the possibility for recognition was the performance of stereotypical Discourses for physicist that relied on traditional gender norms for the field. The results demonstrated that achieving recognition as a competent physicist often involved a complex negotiation of gender roles and the practice of physics.

2010-12-01

A building project of Radiotherapy & Nuclear Medicine services (diagnostic and therapy), within an Integral Oncology Center (IOC), requires interdisciplinary participation of architects, biomedical engineers, radiation oncologists and medical physicists. This report focus on the medical physicist role in designing, building and commissioning stages, for the final clinical use of an IOC at the Oaxaca High Specialization Regional Hospital (HRAEO). As a first step, during design stage, the medical physicist participates in discussions about radiation safety and regulatory requirements for the National Regulatory Agency (called CNSNS in Mexico). Medical physicists propose solutions to clinical needs and take decisions about installing medical equipment, in order to fulfill technical and medical requirements. As a second step, during the construction stage, medical physicists keep an eye on building materials and structural specifications. Meanwhile, regulatory documentation must be sent to CNSNS. This documentation compiles information about medical equipment, radioactivity facility, radiation workers and nuclear material data, in order to obtain the license for the linear accelerator, brachytherapy and nuclear medicine facilities. As a final step, after equipment installation, the commissioning stage takes place. As the conclusion, we show that medical physicists are essentials in order to fulfill with Mexican regulatory requirements in medical facilities.

2004-09-01

Excessive pain during medical procedures performed in unanesthetized patients is frequently reported, but can be reduced with virtual reality (VR) distraction. Increasing the person's illusion of going into the virtual world may increase how effectively VR distracts pain. Healthy volunteers aged 18-20 years participated in a double-blind between-groups design. Each subject received a brief baseline thermal pain stimulus, and the same stimulus again minutes later with either a Low Tech or a High Tech VR distraction. Each subject provided subjective 0-10 ratings of cognitive, sensory and affective components of pain, and rated their illusion of going inside the virtual world. Subjects in the High Tech VR group reported a stronger illusion of going into the virtual world (VR presence) than subjects in the Low Tech VR group, (4.2 vs. 2.5, respectively, P = 0.009) and more pain reduction (reduction of worst pain is 3.1 for High Tech VR vs. 0.7 for Low Tech VR, P < 0.001). Across groups, the amount of pain reduction was positively and significantly correlated with VR presence levels reported by subjects ( r = 0.48 for 'worst pain', P < 0.005).

Over 73% of hi-tech industry employees in Taiwan lack regular exercise. They are exposed to a highly variable and stressful work environment for extended periods of time, and may subsequently experience depression, detrimental to workers' physiological and mental health. In this cross-sectional survey, the authors explored the effect of an 8-week brisk walking program on the fatigue of employees in the hi-tech industry. The participants, from a hi-tech company in northern Taiwan, were randomly assigned to an experimental group (EG; 41 subjects, Mage = 33.34 ± 6.40) or control group (CG; 45 subjects, Mage = 29.40 ± 3.60). Following the 8-week brisk walking program, the EG showed significantly lower scores for subjective fatigue, working motivation, attention, and overall fatigue. The authors confirmed that the 8-week outdoor brisk walking program significantly improved the level of fatigue among employees of the hi-tech industry. The finding serves as an important reference for health authorities in Taiwan and provides awareness of workplace health promotion in the hi-tech industry. © 2015 The Author(s).

Arenson, R.

With the profound changes currently occurring in medicine, the role of the medical physicist cannot stagnate, but must evolve to meet the challenges and opportunities that are presented. Medical physicists must understand these changes and establish themselves not only as relevant but as leaders in this new environment. We must increase our presence in clinical settings such as tumor boards, patient rounds, and the development of new diagnosis, imaging, and treatment techniques. By establishing ourselves as competent scientists, we can and must participate in the development of technologies through research, teaching, and clinical implementation. As medical physicists we must definemore » our roles and value to our physician colleagues, patients, referring physicians, and senior administrators. We cannot afford to be viewed solely as quality assurance technologists, but need to move forward in step with medical and practice advances, becoming recognized as having a leadership role in providing quality research, technological development, and quality patient care. In this session, four leaders in medical research and healthcare will discuss their observations on how medical physicists have contributed to advancements in healthcare and opportunities to continue leadership in providing quality medicine through the applications of physics to research, education, and clinical practice. Learning Objectives: Understand the changes in the healthcare environment and how medical physicists can contribute to improving patient care. Learn how medical physicists are currently leading research efforts to improve clinical imaging and diagnosis. Understand the role of medical physicists in developing new technology and leading its translation into clinical care.« less

SU-F-P-13: NRG Oncology Medical Physics Manpower Survey Quantifying Support Demands for Multi Institutional Clinical Trials

DOE Office of Scientific and Technical Information (OSTI.GOV)

Monroe, J; Case Western Reserve University; Boparai, K

Purpose: A survey was taken by NRG Oncology to assess Full Time Equivalent (FTE) contributions to multi institutional clinical trials by medical physicists.No current quantification of physicists’ efforts in FTE units associated with clinical trials is available. The complexity of multi-institutional trials increases with new technologies and techniques. Proper staffing may directly impact the quality of trial data and outcomes. The demands on physics time supporting clinical trials needs to be assessed. Methods: The NRG Oncology Medical Physicist Subcommittee created a sixteen question survey to obtain this FTE data. IROC Houston distributed the survey to their list of 1802 contactmore » physicists. Results: After three weeks, 363 responded (20.1% response). 187 (51.5%) institutions reporting external beam participation were processed. There was a wide range in number of protocols active and supported at each institution. Of the 187 clinics, 134 (71.7%) participate in 0 to 10 trials, 28 (15%) in 11 to 20 trials, 10 (5.3%) in 21 to 30 trials, 9 (4.8%) had 40 to 75 trials. On average, physicist spent 2.7 hours (SD: 6.0) per week supervising or interacting with clinical trial staff. 1.25 hours (SD: 3.37), 1.83 hours (SD: 4.13), and 0.64 hours(SD: 1.13) per week were spent on patient simulation, reviewing treatment plans, and maintaining a DICOM server, respectively. For all protocol credentialing activities, physicist spent an average of 37.05 hours (SD: 96.94) yearly. To support dosimetrists, clinicians, and therapists, physicist spend on average 2.07 hours (SD: 3.52) per week just reading protocols. Physicist attended clinical trial meetings for on average 1.13 hours (SD: 1.85) per month. Conclusion: Responding physicists spend a nontrivial amount of time: 8.8 hours per week (0.22 FTE) supporting, on average, 9 active multi-institutional clinical trials.« less

TU-F-BRD-01: Biomedical Informatics for Medical Physicists

DOE Office of Scientific and Technical Information (OSTI.GOV)

Phillips, M; Kalet, I; McNutt, T

Biomedical informatics encompasses a very large domain of knowledge and applications. This broad and loosely defined field can make it difficult to navigate. Physicists often are called upon to provide informatics services and/or to take part in projects involving principles of the field. The purpose of the presentations in this symposium is to help medical physicists gain some knowledge about the breadth of the field and how, in the current clinical and research environment, they can participate and contribute. Three talks have been designed to give an overview from the perspective of physicists and to provide a more in-depth discussionmore » in two areas. One of the primary purposes, and the main subject of the first talk, is to help physicists achieve a perspective about the range of the topics and concepts that fall under the heading of 'informatics'. The approach is to de-mystify topics and jargon and to help physicists find resources in the field should they need them. The other talks explore two areas of biomedical informatics in more depth. The goal is to highlight two domains of intense current interest--databases and models--in enough depth into current approaches so that an adequate background for independent inquiry is achieved. These two areas will serve as good examples of how physicists, using informatics principles, can contribute to oncology practice and research. Learning Objectives: To understand how the principles of biomedical informatics are used by medical physicists. To put the relevant informatics concepts in perspective with regard to biomedicine in general. To use clinical database design as an example of biomedical informatics. To provide a solid background into the problems and issues of the design and use of data and databases in radiation oncology. To use modeling in the service of decision support systems as an example of modeling methods and data use. To provide a background into how uncertainty in our data and knowledge can be incorporated into modeling methods.« less

To determine the effects on weight loss of three abbreviated behavioral weight loss interventions with and without coaching and mobile technology. A randomized controlled efficacy study of three 6-month weight loss treatments was conducted in 96 adults with obesity: 1) self-guided (SELF), 2) standard (STND), or 3) technology-supported (TECH). STND and TECH received eight in-person group treatment sessions. SELF and STND used paper diaries to self-monitor diet, activity, and weight; TECH used a smartphone application with social networking features and wireless accelerometer. Weight loss was greater for TECH and STND than SELF at 6 months (-5.7 kg [95% confidence interval: -7.2 to -4.1] vs. -2.7 kg [95% confidence interval: -5.1 to -0.3], P < 0.05) but not 12 months. TECH and STND did not differ except that more STND (59%) than TECH (34%) achieved ≥ 5% weight loss at 6 months (P < 0.05). Self-monitoring adherence was greater in TECH than STND (P < 0.001), greater in both interventions than SELF (P < 0.001), and covaried with weight loss (r(84) = 0.36-0.51, P < 0.001). Abbreviated behavioral counseling can produce clinically meaningful weight loss regardless of whether self-monitoring is performed on paper or smartphone, but long-term superiority over standard of care self-guided treatment is challenging to maintain. © 2017 The Obesity Society.

What if Things Get Worse? Really Grand Challenges for Modeling and Simulation in a Risky and Complex World or Modeling and Simulation for the "Greater Good"?

NASA Technical Reports Server (NTRS)

Today Modeling and Simulation-- ---as an important practice or industry or area of expertise ----- is at a complex crossroad - a sort of cyber-highway--where these complexities meet-technical, economic, environmental, geopolitical and cultural. They may converge or collide. Let's not kid ourselves. It is all too much for anyone person or organization Malcolm Gladwell said it. "We have constructed a world in which the potential for high tech catastrophe is embedded in the fabric of everyday life." We are surrounded by problems that scream at us from our television, Internet and social networks along with billboards and protest signs. We face not just high tech catastrophes but, also, landslides, earthquakes, tornados, floods and hurricanes and large-scale criminality. Evil, war, famine and pestilence have not gone away. It is all too much to think about. My friend, George Peabody, who taught me everything I know about power said that addressing such issues requires that we constantly build our network, information resources and the credibility and visibility of our work. That is how we will build the power of simulation so it can change the world --even maybe, save it. We need all the help we can get and give one another because our human early warning systems appear to be out of kilter. We seem to have trouble imagining how small failings can continue to lead to catastrophic disaster. Think about O-rings and blowout preventers. One is reminded of the old nursery rhyme, "For want of a nail, a shoe was lost! for want of a shoe the horse was lost! for want of a rider the battle was lost and so the kingdom fell." Although the investigation will take more time for real answers, it is worrisome that a rig worker reported to the BBC that-- weeks before the explosion of Deep Ocean Horizon. -he identified a leak in the oil rig's safety equipment -the Control Pod of the blowout preventer which has giant shears designed to cut and seal off the well's main pipe. With both electronics and hydraulics, these are effectively the brains of the blowout preventer. No one fixed it, he alleges, they just shut it down and relied on the other control pod -an act deemed unacceptable by petroleum expert, Tad Patzek, at the University of Texas. The US Congress has identified numerous other problems with the blowout preventer, including design problems and unexpected modifications.

SU-F-T-250: What Does It Take to Correctly Assess the High Failure Modes of an Advanced Radiotherapy Procedure Such as Stereotactic Body Radiation Therapy?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Han, D; Vile, D; Rosu, M

Purpose: Assess the correct implementation of risk-based methodology of TG 100 to optimize quality management and patient safety procedures for Stereotactic Body Radiation Therapy. Methods: A detailed process map of SBRT treatment procedure was generated by a team of three physicists with varying clinical experience at our institution to assess the potential high-risk failure modes. The probabilities of occurrence (O), severity (S) and detectability (D) for potential failure mode in each step of the process map were assigned by these individuals independently on the scale from1 to 10. The risk priority numbers (RPN) were computed and analyzed. The highest 30more » potential modes from each physicist’s analysis were then compared. Results: The RPN values assessed by the three physicists ranged from 30 to 300. The magnitudes of the RPN values from each physicist were different, and there was no concordance in the highest RPN values recorded by three physicists independently. The 10 highest RPN values belonged to sub steps of CT simulation, contouring and delivery in the SBRT process map. For these 10 highest RPN values, at least two physicists, irrespective of their length of experience had concordance but no general conclusions emerged. Conclusion: This study clearly shows that the risk-based assessment of a clinical process map requires great deal of preparation, group discussions, and participation by all stakeholders. One group albeit physicists cannot effectively implement risk-based methodology proposed by TG100. It should be a team effort in which the physicists can certainly play the leading role. This also corroborates TG100 recommendation that risk-based assessment of clinical processes is a multidisciplinary team effort.« less

MO-DE-304-01: The Abt Study of Medical Physicist Work Values for Radiation Oncology Physics Services: Round IV

DOE Office of Scientific and Technical Information (OSTI.GOV)

Mills, M.

The Abt study of medical physicist work values for radiation oncology physics services, Round IV is completed. It supersedes the Abt III study of 2008. The 2015 Abt study measured qualified medical physicist (QMP) work associated with routine radiation oncology procedures as well as some special procedures. As before, a work model was created to allow the medical physicist to defend QMP work based on both routine and special procedures service mix. The work model can be used to develop a cost justification report for setting charges for radiation oncology physics services. The Abt study Round IV was designed tomore » empower the medical physicist to negotiate a service or employment contract with providers based on measured national QMP workforce and staffing data. For a variety of reasons, the diagnostic imaging contingent of AAPM has had a more difficult time trying estimate workforce requirements than their therapy counterparts. Over the past several years, the Diagnostic Work and Workforce Study Subcommittee (DWWSS) has collected survey data from AAPM members, but the data have been very difficult to interpret. The DWWSS has reached out to include more AAPM volunteers to create a more full and accurate representation of actual clinical practice models on the subcommittee. Though much work remains, through hours of discussion and brainstorming, the DWWSS has somewhat of a clear path forward. This talk will provide attendees with an update on the efforts of the subcommittee. Learning Objectives: Understand the new information documented in the Abt studies. Understand how to use the Abt studies to justify medical physicist staffing. Learn relevant historical information on imaging physicist workforce. Understand the process of the DWWSS in 2014. Understand the intended path forward for the DWWSS.« less

A maintenance program generated through the consideration of characteristics and failures of medical equipment is an important component of technology management. However, older technology devices and newer high-tech devices cannot be efficiently managed using the same strategies because of their different characteristics. This study aimed to generate a maintenance program comprising two different strategies to increase the efficiency of device management: preventive maintenance for older technology devices and predictive maintenance for newer high-tech devices. For preventive maintenance development, 589 older technology devices were subjected to performance verification and safety testing (PVST). For predictive maintenance development, the manufacturers' recommendations were used for 134 high-tech devices. These strategies were evaluated in terms of device reliability. This study recommends the use of two different maintenance strategies for old and new devices at hospitals in developing countries. Thus, older technology devices that applied only corrective maintenance will be included in maintenance like high-tech devices.

Displacement in new economy labor markets: Post-displacement wage loss in high tech versus low tech cities.

PubMed

Davis, Daniel J; Rubin, Beth A

2016-11-01

While scholars and politicians tout education as the salve to employment disruptions, we argue that the geography of the new economy, and the social closure mechanisms that geography creates, may be just as important as individuals' characteristics for predicting post-displacement wage loss (or gain). We use data from the 2012 Displaced Workers ement of the Current Population Survey and from the 2010 United States Census to test hypotheses linking local labor markets in different industrial contexts to post-displacement wage loss. Our results point to age as a closure mechanism, and to the partially protective effect of education in high-tech versus low-tech economic sectors. This study is the first to use national level data to examine how employment in high-tech cities influences post-displacement wages. These findings are relevant both for theorizing about the new economy and for public policy. Copyright © 2016 Elsevier Inc. All rights reserved.

Although high-tech augmentative and alternative communication (AAC) is commonly used to teach social-communication skills to people with autism spectrum disorder or intellectual disabilities who have complex communication needs, there is a critical need to evaluate the efficacy of this approach. The aim of this systematic review was to evaluate the quality of single-case experimental design research on the use of high-tech AAC to teach social-communication skills to individuals with autism spectrum disorder or intellectual disabilities who have complex communication needs, to determine if this intervention approach meets the criteria for evidence-based practices as outlined by the What Works Clearinghouse. Additionally, information on the following extended methodological standards is reported on all included studies: participant description, description of setting and materials, interventionist description, baseline and intervention description, maintenance, generalization, procedural integrity, and social validity. The results from 18 multiple-baseline or multiple-probe experiments across 17 studies indicate that using high-tech AAC to teach social-communication skills to individuals with autism spectrum disorder or intellectual disabilities and complex communication needs can be considered an evidence-based practice, although the review of comparison (i.e., alternating treatment) design studies did not indicate that high-tech AAC is significantly better than low-tech AAC.

As the host of the Olympic Village for the 1996 Atlanta Olympics, Georgia Tech has experienced a surge in construction activities over the last three years. Over 1.3 million square feet of new buildings have been constructed on the Georgia Tech campus. This growth has placed a strain on the Georgia Tech community and challenged the facilities support staff charged with planning and organizing utility services. In concert with Olympic construction, utility planners have worked to ensure long term benefits for Georgia Tech facilities while meeting the short term requirements of the Olympic Games. The concentration of building construction inmore » the northwest quadrant of the campus allowed planners to construct a satellite chilled water plant to serve the needs of this area and provide the opportunity to integrate this section of the campus with the main campus chilled water system. This assessment and master plan, funded in part by the US Department of Energy, has evaluated the chilled water infrastructure at Georgia Tech, identified ongoing problems and made recommendations for long term chilled water infrastructure development and efficiency improvements.

Kragh, Helge

Abraham Pais made important contributions to the physics of elementary particles and other areas of theoretical physics before he turned, in the 1970s, to the history of modern physics, a field he cultivated energetically and successfully until his death in 2000. Among the best works of the prolific physicist-historian (a better term, in this case, than historian of physics) is the acclaimed Einstein biography Subtle is the Lord (1982) and Inward Bound (1986), a comprehensive chronicle of elementary particle physics. More recently his autobiography, A Tale of Two Continents (1997), appeared, a book to a large extent based on Pais's friendship and acquaintance with many of the greatest physicists of the twentieth century. In the present book, the physicists who appeared as supporting cast in his autobiography are presented in their own right, chapter by chapter. Yet Pais himself is present throughout the book and the reader is constantly reminded of his friendship with the physicists portrayed.

The members of the Swain family- Dr. Charles "Bill" Swain, wife Elaine, daughter Carol, 17, son "Chuck", 12, and dog Susie have an interesting assignment. They are active participants in an important NASA research program involving the application of space-age technology to home construction. b' Transplanted Floridians, the Swains now reside in NASA's Tech House, loatedat Langley Research Center, Hampton, Virginia. Their job is to use and help evaluate the variety of advanced technology systems in Tech House. A contemporary three-bedroom home, Tech House incorporates NASA technology, the latest commercial building techniques and other innovations, all designed to reduce energy and water consumption and to provide new levels of comfort, convenience, security and fire safety. Tech House equipment performed well in initial tests, but a house is not a home until it has people. That's where the Swains come in. NASA wants to see how the various systems work under actual living conditions, to confirm the effectiveness of the innovations or to determine necessary modifications for improvement. The Swains are occupying the house for a year, during which NASA engineers are computer monitoring the equipment and assembling a record of day-to-day performance. . Tech House is a laboratory rather than a mass production prototype, but its many benefits may influence home design and construction. In a period of sharply rising utility costs, widespread adoption of Tech House features could provide large-scale savings to homeowners and potentially enormous national benefit in resources conservation. Most innovations are aerospace spinoffs: Some of the equipment is now commercially available; other systems are expected to be in production within a few years. Around 1980, a Tech House-type of home could be built for $45-50,000 (1 976 dollars). It is estimated that the homeowner would save well over $20,000 (again 1976 dollars) in utility costs over the average mortgage span of 20 years.

Converting Radiology Operations in a Six-Hospital Healthcare System from Film-Based to Digital: Another Leadership Role for the Diagnostic Medical Physicist

Arreola, Manuel M.; Rill, Lynn N.

2004-09-01

As medical facilities across the United States continue to convert their radiology operations from film-based to digital environments, partially accomplished and failed endeavors are frequent because of the lack of competent and knowledgeable leadership. The diagnostic medical physicist is, without a doubt, in a privileged position to take such a leadership role, not only because of her/his understanding of the basics principles of new imaging modalities, but also because of her/his inherent participation in workflow design and educational/training activities. A well-structured approach by the physicist will certainly lead the project to a successful completion, opening, in turn, new opportunities for the medical physicist to become an active participant in the decision-making process for an institution.

This paper reports on a survey of medical physicists who write and use in-house written software as part of their professional work. The goal of the survey was to assess the extent of in-house software usage and the desire or need for related software quality guidelines. The survey contained eight multiple-choice questions, a ranking question, and seven free text questions. The survey was sent to medical physicists associated with cancer centers across Canada. The respondents to the survey expressed interest in having guidelines to help them in their software-related work, but also demonstrated extensive skills in the area of testing, safety, and communication. These existing skills form a basis for medical physicists to establish a set of software quality guidelines.

The experience for women in physics remains challenging in Belarus. The proportion of female physics master's degree recipients is approximately 30%, while the percentage of female physics PhD recipients is 50%. Still, only a few female physicists occupy top positions in research laboratories, institutes, or universities. The basic problem for career-oriented female physicists in Belarus is public opinion, which cultivates a passive and dependent life philosophy for women. The Belarusian Women in Physics group was formed in 2003 as part of the Belarusian Physical Society.

With the structural change of global supply chains, the relationship between manufacturers and suppliers has transformed into a long-term partnership. Thus, this study aims to explore the partnership between manufacturers and suppliers in Taiwan's high-tech industry. Four constructs, including partner characteristic, partnership quality, partnership closeness, and cooperative performance, induced from previous literatures are used to construct the research framework and hypotheses. A questionnaire survey is then performed on executives and staffs involved in the high-tech industry. The proposed framework and hypotheses are empirically validated through confirmatory factory analysis and structural equation modeling. It is expected that the research findings can serve as a reference for Taiwan's high-tech industry on building partnerships.

Research Center Renaming Will Honor Senator Domenici

NASA Astrophysics Data System (ADS)

2008-05-01

New Mexico Tech and the National Radio Astronomy Observatory (NRAO) will rename the observatory's research center on the New Mexico Tech campus to honor retiring U.S. Senator Pete V. Domenici in a ceremony on May 30. The building that serves as the scientific, technical, and administrative center for the Very Large Array (VLA) and Very Long Baseline Array (VLBA) radio telescopes will be named the "Pete V. Domenici Science Operations Center." The building previously was known simply as the "Array Operations Center." Sen. Pete V. Domenici Sen. Pete V. Domenici "The new name recognizes the strong and effective support for science that has been a hallmark of Senator Domenici's long career in public service," said Dr. Fred Lo, NRAO Director. New Mexico Tech President Daniel H. Lopez said Sen. Domenici has always been a supporter of science and research in Socorro and throughout the state. "He's been a statesman for New Mexico, the nation -- and without exaggeration -- for the world," Lopez said. "Anyone with that track record deserves this recognition." Van Romero, Tech vice president of research and economic development, has served as the university's main lobbyist in Washington, D.C., for more than a decade. He said Sen. Domenici has always been receptive to new ideas and willing to take risks. "Over the years, Sen. Domenici has always had time to listen to our needs and goals," Romero said. "He has served as a champion of New Mexico Tech's causes and we owe him a debt of gratitude for all his efforts over the decades." Originally dedicated in 1988, the center houses offices and laboratories that support VLA and VLBA operations. The center also supports work on the VLA modernization project and on the international Atacama Large Millimeter/submillimeter Array (ALMA) project. Work on ALMA at the Socorro center and at the ALMA Test Facility at the VLA site west of Socorro has focused on developing and testing equipment to be deployed at the ALMA site in Chile's Atacama Desert. The research facility, part of the National Science Foundation-funded NRAO, was located on the NM Tech campus through a joint Federal-State effort spearheaded by Domenici. "Senator Domenici has worked hard over the years to support research both at New Mexico Tech and at the NRAO, and our facility on the New Mexico Tech campus is a symbol of that support. It's highly appropriate to name it after him," said Dr. Ethan Schreier, President of Associated Universities Inc., which operates the NRAO for the National Science Foundation. Senator Domenici helped make New Mexico Tech's Magdalena Ridge Observatory (MRO) a reality and provided essential support for NRAO's VLA and VLBA. MRO is one of the world's most technologically-advanced optical observatories. The VLA is the most scientifically-productive ground-based telescope in the history of astronomy. "Both these facilities will advance the frontiers of 21st-Century astrophysics, and keep our state and its research community in the forefront of science worldwide," said Dr. Robert Dickman, NRAO's Director for New Mexico Operations. Domenici also was instrumental in bringing the International Law Enforcement Academy -- another New Mexico Tech division -- to Roswell. During the Reagan Administration, Domenici sponsored the legislation that allowed the university to use the "M" Mountain range for research and testing. Lopez said the U.S. Department of the Interior would not let the university conduct testing on the range. A high level bureaucrat told Laurence Lattman, then the president of Tech, that it "would take an act of Congress" for Tech to have unlimited access to the land. Domenici sponsored the legislation -- signed by Reagan -- that gave Tech access to the land. Over the years, Domenici's support has helped Tech launch the homeland security training program in Playas, the EarthScope research and other anti-terrorism training programs. "All these projects benefit New Mexico Tech," Lopez said. "But these programs also benefit the nation. Senator Domenici has always been careful to make sure that federal money went to programs that benefit the entire nation." The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

What physicists should learn about finance (if they want to)

Schmidt, Anatoly

2006-03-01

There has been growing interest among physicists to Econophysics, i.e. analysis and modeling of financial and economic processes using the concepts of theoretical Physics. There has been also perception that the financial industry is a viable alternative for those physicists who are not able or are not willing to pursue career in their major field. However in our times, the Wall Street expects from applicants for quantitative positions not only the knowledge of the stochastic calculus and the methods of time series analysis but also of such concepts as option pricing, portfolio management, and risk measurement. Here I describe a synthetic course based on my book ``Quantitative Finance for Physicists'' (Elsevier, 2004) that outlines both worlds: Econophysics and Mathematical Finance. This course may be offered as elective for senior undergraduate or graduate Physics majors.

It is vitally important that medical physicists understand the clinical questions that radiologists are trying to answer with patient images. Knowledge of the types of information the radiologist needs helps medical physicists configure imaging protocols that appropriately balance radiation dose, time, and image quality. The ability to communicate with radiologists and understand medical terminology, anatomy, and physiology is key to creating such imaging protocols. In this session, radiologists will present clinical cases and describe the information they are seeking in the clinical images. Medical physicists will then discuss how imaging protocols are configured. Learning Objectives: Understand the types of informationmore » that radiologists seek in medical images. Apply this understanding in configuring the imaging equipment to deliver this information. Develop strategies for working with physician colleagues.« less

Radiative transfer and spectroscopic databases: A line-sampling Monte Carlo approach

Galtier, Mathieu; Blanco, Stéphane; Dauchet, Jérémi; El Hafi, Mouna; Eymet, Vincent; Fournier, Richard; Roger, Maxime; Spiesser, Christophe; Terrée, Guillaume

2016-03-01

Dealing with molecular-state transitions for radiative transfer purposes involves two successive steps that both reach the complexity level at which physicists start thinking about statistical approaches: (1) constructing line-shaped absorption spectra as the result of very numerous state-transitions, (2) integrating over optical-path domains. For the first time, we show here how these steps can be addressed simultaneously using the null-collision concept. This opens the door to the design of Monte Carlo codes directly estimating radiative transfer observables from spectroscopic databases. The intermediate step of producing accurate high-resolution absorption spectra is no longer required. A Monte Carlo algorithm is proposed and applied to six one-dimensional test cases. It allows the computation of spectrally integrated intensities (over 25 cm-1 bands or the full IR range) in a few seconds, regardless of the retained database and line model. But free parameters need to be selected and they impact the convergence. A first possible selection is provided in full detail. We observe that this selection is highly satisfactory for quite distinct atmospheric and combustion configurations, but a more systematic exploration is still in progress.

Hubbert's Peak: A Physicist's View

NASA Astrophysics Data System (ADS)

McDonald, Richard

2011-11-01

Oil and its by-products, as used in manufacturing, agriculture, and transportation, are the lifeblood of today's 7 billion-person population and our 65T world economy. Despite this importance, estimates of future oil production seem dominated by wishful thinking rather than quantitative analysis. Better studies are needed. In 1956, Dr. M.King Hubbert proposed a theory of resource production and applied it successfully to predict peak U.S. oil production in 1970. Thus, the peak of oil production is referred to as ``Hubbert's Peak.'' Prof. Al Bartlett extended this work in publications and lectures on population and oil. Both Hubbert and Bartlett place peak world oil production at a similar time, essentially now. This paper extends this line of work to include analyses of individual countries, inclusion of multiple Gaussian peaks, and analysis of reserves data. While this is not strictly a predictive theory, we will demonstrate a ``closed'' story connecting production, oil-in-place, and reserves. This gives us the ``most likely'' estimate of future oil availability. Finally, we will comment on synthetic oil and the possibility of carbon-neutral synthetic oil for a sustainable future.

The synergy amongst Engineering, Medicine and Biology evolves as fast as these disciplines. We propose to articulate these specialties based on the premise that new professionals must face different situations or crisis due to the so-called islands of excellence. René Favaloro focused his work and struggles against poverty, since malnutrition and environmental degradation may increase the propensity to cardiovascular diseases. Doctor Favaloro has dedicated, throughout his career, a considerable amount of time to prepare and qualify a research group, aware of the importance that an adequate working environment has over the final results. He created a team of young students, engineers, medical doctors, physicists, mathematicians and other specialists. He centered his attention on human resources, in order to disseminate his latest advances in Biology, Medicine and Engineering. We are revising the programs of biomedical engineering education and the application of new pedagogic paradigms, where critical thinking is the key: a holistic challenge that consists of a new way of learning, innovating, communicating and shearing, with a creative attitude that represents quality of perception.

Geballe, T. H.; Kivelson, S. A.

In common with all condensed matter physicists of our generations, our way of thinking about our field was shaped and greatly inspired by countless seminal works of Phil Anderson -- a debt we are pleased to have the opportunity to acknowledge. Discussing plans for this article, we spent many pleasant times debating which particular contribution to highlight -- super-exchange (THG), Anderson-Higgs (SAK), the Anderson--Morel pseudopotential (THG), poor man's scaling (SAK), etc. In the end, we opted to highlight a single specific paper which greatly affected each of us at the time, and which has continued to exert a strong intellectual influence on us in the ensuing years. Almost 40 years ago in Ref. 1, Phil introduced the negative U center to account for the fact that most glasses and amorphous semiconductors are diamagnetic. This paper has been highly influential, but certainly does not rank among Phil's most famous works; however, focusing on it enables us to re-acquaint a younger generation with another of Phil's contributions, and to use this as a springboard to discuss some forward-looking extensions that continue to fascinate us...

The Statistical Fragmentation Theory of N. F. Mott

NASA Astrophysics Data System (ADS)

Grady, Dennis

2004-07-01

For a brief period during the height of World War II, Neville F. Mott left his position at the University of Bristol and headed up a concerted theoretical effort at Fort Halstead, UK, to investigate the operational science of weapons and armor technology. The seminal achievements resulting from the efforts of the participating scientists are extraordinary and have provided the basis for much of the continuing research in this field over the intervening six decades. N. F. Mott chose to study the phenomenon of the explosive-driven fragmentation of exploding shell cases. The approaches pursued by Mott are documented in several interim reports and open literature publications and offer a fascinating look into the insightful thinking and scientific methods of one of the preeminent physicists of the last century. This presentation offers a perspective into the several theoretical approaches pursued by Mott. In particular, the hallmark relation for the representation of exploding munitions fragmentation data to the present day is the Mott distribution. The efforts of Mott leading to this distribution are explored and a judgment is offered as to whether Mott himself would use this distribution today.

Classroom interactions provide learning opportunities for understanding others and developing agency in a community of learners. Student learning identities were measured using a survey instrument targeting physics learning self-efficacy, expectations of classroom roles, and attitude toward social learning as components of physics learning identity. From a selection of students who scored relatively high or low on the survey sub scales, an academically successful student in an introductory physics course using an active engagement curriculum was selected to examine identity development. Findings indicate he didn't develop a sense of agency, nor did he feel a need to alter his participation, although there were ample opportunities to do so in the learning community. These results suggest that being a successful physics student in the traditional sense doesn't necessarily mean the student is successful at adopting meta-goals which are the non-content course goals of learning to think like a physicist. This student was prompted to engage meaningfully but didn't feel it was required for success which suggests that structural alignment is required to motivate students to achieve meta-goals.

Porter, Lisa

2009-05-01

Over the past several decades, physicists have made seminal contributions to technological capabilities that have enabled the U.S. intelligence community to provide unexpected and unparalleled information to our nation's decision makers and help dispel the cloud of uncertainty they face in dealing with crises and challenges around the world. As we look to the future, we recognize that the ever-quickening pace of changes in the world and the threats we must confront demand continued innovation and improvement in the capabilities needed to provide the information on which our leaders depend. This talk will focus on some of the major technological challenges that the intelligence community faces in the coming years, and the many ways that physicists can help to overcome those challenges. The potential impact of physicists on the future capabilities of the US intelligence community is huge. In addition to the more obvious and direct impact through research in areas ranging from novel sensors to quantum information science, the unique approach physicists bring to a problem can also have an indirect but important effect by influencing how challenges in areas ranging from cybersecurity to advanced analytics are approached and solved. Several examples will be given.

Medical physics is alive and well and growing in South East Asia.

In recent years there has been a significant economic growth in South East Asia, along with it a concurrent development of medical physics. The status of four countries--Malaysia, Thailand, the Philippines and Indonesia are presented. Medical physicists in these countries have been experiencing the usual problems of lack of recognition, low salaries, and insufficient facilities for education and training opportunities. However the situation has improved recently through the initiative of local enthusiastic medical physicists who have started MS graduate programs in medical physics and begun organizing professional activities to raise the profile of medical physics. The tremendous support and catalytic roles of the American Association of Physicists in Medicine (AAPM) and international organizations such as International Organization for Medical Physics (IOMP), International Atomic Energy Agency (IAEA), World Health Organization (WHO), and International Center for Theoretical Physics (ICTP) have been instrumental in achieving progress. Contributions by these organizations include co-sponsorship of workshops and conferences, travel grants, medical physics libraries programs, and providing experts and educators. The demand for medical physicists is expected to rise in tandem with the increased emphasis on innovative technology for health care, stringent governmental regulation, and acceptance by the medical community of the important role of medical physicists.

New generation extracorporeal membrane oxygenation with MedTech Mag-Lev, a single-use, magnetically levitated, centrifugal blood pump: preclinical evaluation in calves.

PubMed

Fujiwara, Tatsuki; Nagaoka, Eiki; Watanabe, Taiju; Miyagi, Naoto; Kitao, Takashi; Sakota, Daisuke; Mamiya, Taichi; Shinshi, Tadahiko; Arai, Hirokuni; Takatani, Setsuo

2013-05-01

We have evaluated the feasibility of a newly developed single-use, magnetically levitated centrifugal blood pump, MedTech Mag-Lev, in a 3-week extracorporeal membrane oxygenation (ECMO) study in calves against a Medtronic Bio-Pump BPX-80. A heparin- and silicone-coated polypropylene membrane oxygenator MERA NHP Excelung NSH-R was employed as an oxygenator. Six healthy male Holstein calves with body weights of about 100 kg were divided into two groups, four in the MedTech group and two in the Bio-Pump group. Under general anesthesia, the blood pump and oxygenator were inserted extracorporeally between the main pulmonary artery and the descending aorta via a fifth left thoracotomy. Postoperatively, both the pump and oxygen flow rates were controlled at 3 L/min. Heparin was continuously infused to maintain the activated clotting time at 200-240 s. All the MedTech ECMO calves completed the study duration. However, the Bio-Pump ECMO calves were terminated on postoperative days 7 and 10 because of severe hemolysis and thrombus formation. At the start of the MedTech ECMO, the pressure drop across the oxygenator was about 25 mm Hg with the pump operated at 2800 rpm and delivering 3 L/min flow. The PO2 of the oxygenator outlet was higher than 400 mm Hg with the PCO2 below 45 mm Hg. Hemolysis and thrombus were not seen in the MedTech ECMO circuits (plasma-free hemoglobin [PFH] < 5 mg/dL), while severe hemolysis (PFH > 20 mg/dL) and large thrombus were observed in the Bio-Pump ECMO circuits. Plasma leakage from the oxygenator did not occur in any ECMO circuits. Three-week cardiopulmonary support was performed successfully with the MedTech ECMO without circuit exchanges. The MedTech Mag-Lev could help extend the durability of ECMO circuits by the improved biocompatible performances. © 2013, Copyright the Authors.

Sanderson, Allen R; Chen, Guoning; Tricoche, Xavier; Pugmire, David; Kruger, Scott; Breslau, Joshua

2010-01-01

In the development of magnetic confinement fusion which will potentially be a future source for low cost power, physicists must be able to analyze the magnetic field that confines the burning plasma. While the magnetic field can be described as a vector field, traditional techniques for analyzing the field's topology cannot be used because of its Hamiltonian nature. In this paper we describe a technique developed as a collaboration between physicists and computer scientists that determines the topology of a toroidal magnetic field using fieldlines with near minimal lengths. More specifically, we analyze the Poincaré map of the sampled fieldlines in a Poincaré section including identifying critical points and other topological features of interest to physicists. The technique has been deployed into an interactive parallel visualization tool which physicists are using to gain new insight into simulations of magnetically confined burning plasmas.

Dr. Inside and Dr. Outside: Physicists Involved With National Security and Foreign Policy

NASA Astrophysics Data System (ADS)

Zimmerman, Peter D.

2009-05-01

Physicists have had a special interest in American national security and arms control since at least the Manhattan Project. They have served our country in uniform and in the career civil service. Some have left academic careers for brief periods to work as political appointees, consultants, or resident scholars and then returned to an academic life, but often with changed goals. Some have tried government life and left nearly immediately, while others dipped a toe in and decided to stay. I will look at real-life examples, mostly using real names, drawn from my career and circle of colleagues to try to explain why some physicists have been extremely successful, why others have not, and what happens to a physicist who moved to Washington and decides to stay. I will also discuss routes into public service for those interesting in giving it a try.

Beller Lecture: The Roots of Leo Szilard and his Interdisciplinarity

NASA Astrophysics Data System (ADS)

Marx, George

1998-04-01

A Central European among the whites was said about Leo Szilard who originated from a polycultural family. In the early 20th century he grew up in Hungary, at the crossroads of history, where political regimes, national borders, ideological doctrines, ``final truths'' changed in a dizzying cavalcade. Instead of conservative dogmatism this social environment required critical thinking in order to survive. World War I was the school of Theodore von Kármán, John von Neumann, Eugene P. Wigner and Leo Szilard; each of them learned trespassing political and disciplinary boundaries without inhibition. Their sensitivity for trends had been utilized by the United States when war efforts and high tech required orientation under new horizons. Szilard's interest ranged from statistical physics through information theory to biological evolution, from life phenomena through hot atoms to nuclear strategy. His intellectual adventures might look crazy jumps for specialists. But now, looking back to the political and technological history of the 20th century one can see than it was a consequent progress of a future-sensitive mind.

Interactive Teaching about Landslides and Triggered Landslide Events

NASA Astrophysics Data System (ADS)

Taylor, Faith E.; Malamud, Bruce D.

2015-04-01

When we think of a landslide (mass wasting), both the public and scientists often envisage an individual movement of earth material down a slope. Yet, landslides often occur not as individuals, but as parts of a triggered landslide event. This is where a trigger (e.g., an earthquake or heavy rainfall) results in up to tens of thousands of landslides in a region in the minutes to days after the trigger. The sum of the impacts of these landslides may be greater than individual parts. This interactive Prezi poster will present ideas for innovative demonstrations, teaching practicals and projects, ranging from low-cost low-tech to more advanced digital methods, to communicate the ideas of landslides and triggered landslide events to the public and students. We will give live hands-on demonstrations and welcome discussions with other scientists to share ideas and best practices. This paper is aimed at those in secondary school/university education and the public sector looking for examples to interest and inform their respective audiences about landslides, triggered landslide events, and the importance and implications of considering landslides not just as individuals, but as populations.

SU-E-T-635: Process Mapping of Eye Plaque Brachytherapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Huynh, J; Kim, Y

Purpose: To apply a risk-based assessment and analysis technique (AAPM TG 100) to eye plaque brachytherapy treatment of ocular melanoma. Methods: The role and responsibility of personnel involved in the eye plaque brachytherapy is defined for retinal specialist, radiation oncologist, nurse and medical physicist. The entire procedure was examined carefully. First, major processes were identified and then details for each major process were followed. Results: Seventy-one total potential modes were identified. Eight major processes (corresponding detailed number of modes) are patient consultation (2 modes), pretreatment tumor localization (11), treatment planning (13), seed ordering and calibration (10), eye plaque assembly (10),more » implantation (11), removal (11), and deconstruction (3), respectively. Half of the total modes (36 modes) are related to physicist while physicist is not involved in processes such as during the actual procedure of suturing and removing the plaque. Conclusion: Not only can failure modes arise from physicist-related procedures such as treatment planning and source activity calibration, but it can also exist in more clinical procedures by other medical staff. The improvement of the accurate communication for non-physicist-related clinical procedures could potentially be an approach to prevent human errors. More rigorous physics double check would reduce the error for physicist-related procedures.

The three sessions of the professional development workshop series were each designed for a different audience. The purpose of the first session was to help mid-career physicists aspire for and achieve leadership roles. The second session brought together students, postdoctoral fellows, and early-career physicists to help them plan their career goals and navigate the steps important to launching a successful career. The final session sought to increase awareness of the results of physics education research, and how to use them to help students-especially women-learn physics better. The presentations and discussions were valuable for both female and male physicists.

The Role of Physicists in Policy Making

Since World War II, physicists have been involved in various aspects of national life. The roles played have included: 1) Pure or applied researcher, 2) Advisor to policy makers, and 3) Congressman. Today there are many challenges and questions that the United States faces and scientists, physicists included, are often asked on how these challenges should be addressed. In addressing these concerns what is the ``proper'' role that scientists should play? Do scientists even know what the possible roles are? This talk will briefly address the possible roles that scientists play and what other avenues of input go into the making of policy.

Physicists have made important contributions to many areas of Ford Motor Company activity, particularly in areas of basic and applied research and product development. A number have assumed positions with management responsibility. Many of the technical problems facing the automotive industry today require a fundamental understanding, and the ability of physicists to contribute to the solution of these problems is greater now than it has been in the past. The present paper discusses some of these problems, and also traces a few case histories of physicists at Ford Motor Company; these illustrate the wide diversity of career paths for persons entering industry with a physics background.

Physics Climate as Experienced by LGBT+ Physicists

Long, Elena

2012-02-01

In 2009, Elena Long created the LGBT+ Physicists website (http://lgbtphysicists.x10hosting.com) as a warehouse for resources useful for sexual and gender minorities working in physics. This resource has grown to include networking resources, lists of LGBT-friendly universities and localities, recommendations for enacting positive change in physics communities, and out-reach to other STEM-oriented LGBT organizations. This has been possible in large part by the dynamic community of LGBT+ physicists and allies looking to make physics more welcoming towards our community. In 2011, Elena used hir position as Member at Large on the executive committee of the Forum of Graduate Student Affairs (FGSA) to conduct a climate survey that included, among other things, the first serious look at LGBT+ demographics in physics. The survey focused particularly on issues of language heard and harassment experienced by physicists and was broken down into categories based on race, physical and mental ability, gender, and sexuality. Furthermore, it examined the outcomes of experienced harassment and the reasons for when harassment was not reported. Due to the nature of the study, overlapping demographics, especially ``multiple minorities,'' were also explored. This talk will give a brief history of the LGBT+ Physicists resource as well as an overview of the FGSA study.

An epistemic framing analysis of upper level physics students' use of mathematics

NASA Astrophysics Data System (ADS)

Bing, Thomas Joseph

Mathematics is central to a professional physicist's work and, by extension, to a physics student's studies. It provides a language for abstraction, definition, computation, and connection to physical reality. This power of mathematics in physics is also the source of many of the difficulties it presents students. Simply put, many different activities could all be described as "using math in physics". Expertise entails a complicated coordination of these various activities. This work examines the many different kinds of thinking that are all facets of the use of mathematics in physics. It uses an epistemological lens, one that looks at the type of explanation a student presently sees as appropriate, to analyze the mathematical thinking of upper level physics undergraduates. Sometimes a student will turn to a detailed calculation to produce or justify an answer. Other times a physical argument is explicitly connected to the mathematics at hand. Still other times quoting a definition is seen as sufficient, and so on. Local coherencies evolve in students' thought around these various types of mathematical justifications. We use the cognitive process of framing to model students' navigation of these various facets of math use in physics. We first demonstrate several common framings observed in our students' mathematical thought and give several examples of each. Armed with this analysis tool, we then give several examples of how this framing analysis can be used to address a research question. We consider what effects, if any, a powerful symbolic calculator has on students' thinking. We also consider how to characterize growing expertise among physics students. Framing offers a lens for analysis that is a natural fit for these sample research questions. To active physics education researchers, the framing analysis presented in this dissertation can provide a useful tool for addressing other research questions. To physics teachers, we present this analysis so that it may make them more explicitly aware of the various types of reasoning, and the dynamics among them, that students employ in our physics classes. This awareness will help us better hear students' arguments and respond appropriately.

Shaking Up Biotech/Pharma: Can Cues Be Taken from the Tech Industry?

The biotech and pharma (biotech/pharma) industry is in dire need of finding ways to increase efficacy, efficiency, and affordability of its products. The information and technology industry ("tech") industry, which is an industry similarly founded on inventions and innovation, may provide some food for thought. This perspective will demonstrate the shift that biotech/pharma is already making and will propose that the industry has an opportunity to compel change by adopting some aspects of the tech industry with regards to models for technology/product development and leadership attributes.

Configuring The REU Experience To Maximize Student Collaboration

Majkowski, L.; Pullin, M. J.

2012-12-01

The New Mexico Tech NSF-funded REU Program, Interdisciplinary Science for the Environment (ISE), hosted six cohorts of students between 2005 and 2010. The program ran for eight weeks during the first cycle and nine weeks during the second cycle, bringing in an average of twelve student participants per year. Students were provided with a stipend, food allowance, travel from home to New Mexico Tech, and free campus housing. The program sponsored weekend group field trips to scientific, environmental, and cultural sites of significance in New Mexico. For the second cycle, the ISE shared some programmatic elements with the New Mexico EPSCoR Undergraduate Research Opportunities Program (UROP). The majority of the research projects focused on the geosciences, with interdepartmental participation from researchers in earth science, hydrology, chemistry, environmental science, and biology. The ISE adopted a non-traditional approach to matching student participants with research projects and faculty mentors. Students were selected from different disciplines to work together in pairs on each project. This model provided the students with a peer collaborator in addition to the guidance of their faculty mentors and support from graduate students associated with the different projects. The focus on cohort, both within the individual research projects and each year's group, enabled and enhanced the students' critical thinking, problem-solving and teamwork skills. Students would routinely seek out the advice of their peers when they hit a roadblock in their research. This collaboration also occurred across the boundaries of the ISE and UROP cohorts. Long-term follow up has shown that a significant number of the student participants have continued on to graduate school. Students credit the program with developing their capacity to work on complex problems in an interdisciplinary group environment. Additionally, many students have continued contact with their research partners, faculty mentors and other members of their REU cohort.

Strategies to treat pediatric obesity are needed, especially among high-need populations. Technology is an innovative approach; however, data on technology as adjuncts to in-person treatment programs are limited. A total of 64 children [body mass index (BMI) ≥85th percentile, mean age = 9.6 ± 3.1 years, 32.8% female, 84.4% Hispanic] were recruited to participate in one of three cohorts of a family-based behavioral group (FBBG) treatment program: FBBG only, TECH1, and TECH2. Rolling, nonrandomized recruitment was used to enroll participants into three cohorts from May 2014 to February 2015. FBBG began in May 2014 and received the standard, in-person 12-week treatment only (n = 21); TECH1 began in September 2014 and received FBBG plus a digital tablet equipped with a fitness app (FITNET) (n = 20); TECH2 began in February 2015 and received FBBG and FITNET, plus five individually tailored TeleMed health-coaching sessions delivered via Skype (n = 23). Child BMI z-score (BMI-z) was assessed at baseline and postintervention. Secondary aims examined weekly FBBG attendance, feasibility/acceptability of FITNET and Skype, and the effect of technology engagement on BMI-z. FBBG and TECH1 participants did not show significant reductions in BMI-z postintervention [FBBG: β = -0.05(0.04), p = 0.25; TECH1: β = -0.006(0.06), p = 0.92], but TECH2 participants did [β = -0.09(0.02), p < 0.001] and TeleMed session participation was significantly associated with BMI-z reduction [β = -0.04(0.01), p = 0.01]. FITNET use and FBBG attendance were not associated with BMI-z in any cohort. Overall, participants rated the technology as highly acceptable. Technology adjuncts are feasible, used by hard-to-reach participants, and show promise for improving child weight status in obesity treatment programs.

Federal involvement in simulating economic growth through the development and application of technology policy is currently the subject of serious debate. A recession and the recognition that an internationally competitive economy is a prerequisite for the attainment of national goals have fostered a number of technology policy initiatives aimed at improving the economic competitiveness of American industry. This paper suggests that the successful implementation of U.S. technology policy will require the adoption of a knowledge diffusion model, the development of user oriented information products and services, and a more 'activist' approach on the part of sci/tech librarians in the provision of scientific and technical information (STI). These changes will have a dramatic impact on the sci/tech library of the future and the preparation of sci/tech librarians.

The 2015 Abt study measured qualified medical physicist (QMP) work associated with routine radiation oncology procedures as well as some special procedures. As before, a work model was created to allow the medical physicist to defend QMP work based on both routine and special procedures service mix. The work model can be used to develop a cost justification report for setting charges for radiation oncology physics services. The Abt study Round IV was designed tomore » empower the medical physicist to negotiate a service or employment contract with providers based on measured national QMP workforce and staffing data. For a variety of reasons, the diagnostic imaging contingent of AAPM has had a more difficult time trying estimate workforce requirements than their therapy counterparts. Over the past several years, the Diagnostic Work and Workforce Study Subcommittee (DWWSS) has collected survey data from AAPM members, but the data have been very difficult to interpret. The DWWSS has reached out to include more AAPM volunteers to create a more full and accurate representation of actual clinical practice models on the subcommittee.

2009-12-01

The Georgia Tech Center for Ribosome Adaptation and Evolution, a center funded by the NASA Astrobiology Institute, developed an educational Astrobiology program titled, “Life on the Edge: Astrobiology.” The purpose of the program was to provide educators with the materials, exposure, and skills necessary to prepare our future workforce and to foster student interest in scientific discovery on Earth and throughout the universe. A one-week, non-residential summer enrichment program for high school students was conducted and tested by two high school educators, an undergraduate student, and faculty in the Schools of Biology, and Chemistry and Biochemistry at Georgia Tech. In an effort to promote and encourage entry into teaching careers, Georgia Tech paired in-service teachers in the Georgia Intern-Fellowship for Teachers (GIFT) program with an undergraduate student interested in becoming a teacher through the Tech to Teaching program. The GIFT and Tech to Teaching fellows investigated extremophiles which have adapted to life under extreme environmental conditions. As a result, extremophiles became the focus of a week-long, “Life on the Edge: Astrobiology” curriculum aligned with the Georgia Performance Standards in Biology. Twenty-five high school students explored the adaptation and survival rates for various types of extremophiles exposed to UV radiation and desiccation; students were also introduced to hands-on activities and techniques such as genomic DNA purification, gel electrophoresis, and Polymerase Chain Reaction (PCR). The impact on everyone invested and involved in the Astrobiology program including the GIFT and Tech to Teaching fellows, high school students, and faculty are discussed.

This report provides guidelines for a peer review process between two clinical radiation oncology physicists. While the Task Group's work was primarily focused on ensuring timely and productive independent reviews for physicists in solo practice, these guidelines may also be appropriate for physicists in a group setting, particularly when dispersed over multiple separate clinic locations. To ensure that such reviews enable a collegial exchange of professional ideas and productive critique of the entire clinical physics program, the reviews should not be used as an employee evaluation instrument by the employer. Such use is neither intended nor supported by this Task Group. Detailed guidelines are presented on the minimum content of such reviews, as well as a recommended format for reporting the findings of a review. In consideration of the full schedules faced by most clinical physicists, the process outlined herein was designed to be completed in one working day. PACS numbers: 87.53.Xd, 87.90.+y PMID:16421500

This commentary reports on a forum held in October 2017 in Hobart, Tasmania, attended by 20 Australasian medical physicists, to consider the future role of medical physics, as well as non-medical physics and allied disciplines, in oncology research. Attendees identified important areas of oncology research which physicists can be contributing to, with these evaluated in the context of a set of "Provocative Questions" recently generated by the American Association of Physicists in Medicine. Primary perceived barriers to participation in research were identified, including a "lack of knowledge of cancer science", together with potential solutions. Mechanisms were considered for engagement with the broader scientific community, consumers, advocates and policy makers. In considering future opportunities in oncology research for medical physicists, it was noted that a professional need to focus on the safety and accuracy of current treatments applied to patients, encouraging risk-aversion, is somewhat in competition with the role of physical scientists in the exploration and discovery of new concepts and understandings.

Radiation Oncology Physics and Medical Physics Education

Bourland, Dan

2011-10-01

Medical physics, an applied field of physics, is the applications of physics in medicine. Medical physicists are essential professionals in contemporary healthcare, contributing primarily to the diagnosis and treatment of diseases through numerous inventions, advances, and improvements in medical imaging and cancer treatment. Clinical service, research, and teaching by medical physicists benefits thousands of patients and other individuals every day. This talk will cover three main topics. First, exciting current research and development areas in the medical physics sub-specialty of radiation oncology physics will be described, including advanced oncology imaging for treatment simulation, image-guided radiation therapy, and biologically-optimized radiation treatment. Challenges in patient safety in high-technology radiation treatments will be briefly reviewed. Second, the educational path to becoming a medical physicist will be reviewed, including undergraduate foundations, graduate training, residency, board certification, and career opportunities. Third, I will introduce the American Association of Physicists in Medicine (AAPM), which is the professional society that represents, advocates, and advances the field of medical physics (www.aapm.org).

Women in physics in Bangladesh

Choudhury, Shamima K.

2013-03-01

Bangladesh has had a glorious physics tradition since the beginning of the last century, when the physicist S.N. Bose published a groundbreaking paper with Albert Einstein on Bose-Einstein statistics. However, women in Bangladesh traditionally have not been able to make their way in the realm of science in general and physics in particular. Since Bangladesh achieved independence in 1971, the situation has gradually changed and more and more women choose physics as an academic discipline. The percentage of women students in physics rose from 10% in 1970 to almost 30% in 2010. In recent years, women physicists have actively participated in many activities promoting science and technology, creating awareness among the public about the importance of physics education. The present status of women physicists in academic, research, and administrative programs in the government and private sectors in Bangladesh is reported. The greater inclusion of women scientists, particularly physicists, in policy-making roles on important issues of global and national interest is suggested.

SU-B-BRA-00: The Medical Physicist Value Proposition for Tomorrow and Today

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sherouse, G.

In the current rapidly changing Healthcare environment, many groups are competing for limited resources. How can medical physicists position themselves to be a relevant stakeholder in the discussion of how those resources are allocated Our value goes beyond what can be shown in a business plan and is heavily involved with safety and quality. Three areas will be explored: What is our value? Who needs to receive that message? How do we communicate that message? To help frame the discussion in terms of how other stakeholders may view the value of medical physicists, a physician and an administrator will presentmore » their perspective. Lastly, a multidisciplinary panel will present real life examples of strategies that can be utilized today to establish the value of medical physicists. The presentation of these examples will lead into an interactive question and answer time. V. Willcut, I work for Elekta. There was no research associated with this talk.« less

Physicists in Primary Schools (PIPS) Project: Fun Presentations for Physicists to Take into Schools Worldwide (abstract)

NASA Astrophysics Data System (ADS)

Marks, Ann

2009-04-01

The Physicists in Primary Schools (PIPS) project is a joint venture initiated by the UK Women in Physics Group. A team from the University of Sheffield, with Engineering and Physical Sciences Research Council funding, has developed fun presentations and novel class activities using everyday articles for physicists to take into primary schools. The objectives are to instill enthusiasm in young children-including girls-through the enjoyment and excitement of physics, and support primary school teachers with a curriculum which includes many abstract concepts. All PIPS material is free to download from the Institute of Physics website (www.iop.org/pips), providing PowerPoint presentations and detailed explanations, as well as videos of the activities in classrooms. The topics are suitable for children age 4 to 11 years. There is interest in translating the presentations into other languages as there are few words on the slides and the material is likely valuable for older age groups. The presentations therefore have the potential to be useful worldwide.

Germany-US Nuclear Theory Exchange Program for QCD Studies of Hadrons & Nuclei 'GAUSTEQ'

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dudek, Jozef; Melnitchouk, Wally

GAUSTEQ was a Germany-U.S. exchange program in nuclear theory whose purpose was to focus research efforts on QCD studies of hadrons and nuclei, centered around the current and future research programs of Jefferson Lab and the Gesellschaft fur Schwerionenforschung (GSI) in Germany. GAUSTEQ provided travel support for theoretical physicists at US institutions conducting collaborative research with physicists in Germany. GSI (with its Darmstadt and Helmholtz Institute Mainz braches) served as the German “hub” for visits of U.S. physicists, while Jefferson Lab served as the corresponding “hub” for visits of German physicists visiting U.S. institutions through the reciprocal GUSTEHP (German-US Theorymore » Exchange in Hadron Physics) program. GAUSTEQ was funded by the Office of Nuclear Physics of the U.S. Department of Energy, under Contract No.DE-SC0006758 and officially managed through Old Dominion University in Norfolk, Virginia. The program ran between 2011 and 2015.« less

Medical physicists represent a valuable asset at the disposal of a structured and planned response to nuclear or radiological emergencies (NREs), especially in the hospital environment. The recognition of this fact led the International Atomic Energy Agency (IAEA) and the International Organization for Medical Physics (IOMP) to start a fruitful collaboration aiming to improve education and training of medical physicists so that they may support response efforts in case of NREs. Existing shortcomings in specific technical areas were identified through international consultations supported by the IAEA and led to the development of a project aiming at preparing a specific and standardized training package for medical physicists in support to NREs. The Project was funded through extra-budgetary contribution from Japan within the IAEA Nuclear Safety Action Plan. This paper presents the work accomplished through that project and describes the current steps and future direction for enabling medical physicists to better support response to NREs.

After the War: Women in Physics in the United States

NASA Astrophysics Data System (ADS)

Howes, Ruth H.; Herzenberg, Caroline L.

2015-12-01

This book examines the lives and contributions of American women physicists who were active in the years following World War II, during the middle decades of the 20th century. It covers the strategies they used to survive and thrive in a time where their gender was against them. The percentage of woman taking PhDs in physics has risen from 6% in 1983 to 20% in 2012 (an all-time high for women). By understanding the history of women in physics, these gains can continue. It discusses two major classes of women physicists; those who worked on military projects, and those who worked in industrial laboratories and at universities largely in the late 1940s and 1950s. While it includes minimal discussion of physics and physicists in the 1960s and later, this book focuses on the challenges and successes of women physicists in the years immediately following World War II and before the eras of affirmative actions and the use of the personal computer.

The next 20 years: how customer and workforce attitudes will evolve.

Howe, Neil; Strauss, William

2007-01-01

Business projects with very long time horizons--such as those involving product R&D, workplace design, and total compensation planning--have to contend with a crucial question: What will be the needs, demands, and desires of consumers and employees decades from now? If you think the answer is "Just more of the same," you're in for a surprise. Howe and Strauss, the authors of Generations, The Fourth Turning, Millennials Rising, and other books, have studied the differences among generations for some 30 years. Their extensive research has revealed a fascinating pattern--one so strong that it supports a measure of predictability. On the basis of historical precedent, they say, we can foresee how the generations that are alive today will think and act in decades to come. Three of those generations will still be vital forces in American society 20 years from now: Boomers, Generation X, and Millennials. Their attitudes and behaviors will have profound effects on the economy, the workplace, and social institutions in general. For example, as aging Boomers eschew high-tech medicine in favor of holistic self-care, natural foods, and mind-body healing techniques, some hospitals are opening new wings featuring alternative medicine and spiritual counseling. Gen Xers, having grown up in an era of failing schools and marriages, will remain alienated, disaffected, and pragmatic as they enter midlife. Already the greatest entrepreneurial generation in U.S. history, they will be highly effective at pushing innovation, efficiency, and mass customization. In contrast, young adult Millennials will favor teamwork, close family relationships, job security, and a bland popular culture. Their unprecedented digital empowerment and talent for organizing will create a political powerhouse and may even revitalize the union movement.

A Different Laboratory Tale: Fifty Years of Mössbauer Spectroscopy

NASA Astrophysics Data System (ADS)

Westfall, Catherine

2006-05-01

I explore the fifty-year development of Mössbauer spectroscopy by focusing on three episodes in its development at Argonne National Laboratory: work by nuclear physicists using radioactive sources in the early 1960s, work by solid-state physicists using radioactive resources from the mid- 1960s through the 1970s,and work by solid-state physicists using the Advanced Photon Source from the 1980s to 2005. These episodes show how knowledge about the properties of matter was produced in a national-laboratory context and highlights the web of connections that allow nationallaboratory scientists working at a variety of scales to produce both technological and scientific innovations.

Herbert Fröhlich: A Physicist Ahead of His Time, by G.J. Hyland [Book Review

DOE Office of Scientific and Technical Information (OSTI.GOV)

Devanathan, Ram

This authoritative biography of Herbert Fröhlich (1905-1991), a well-known theoretical physicist, paints an intimate portrait of a pioneering scientist who made seminal contributions to condensed matter physics and left his mark on other domains such as biology over a 60-year career. From his vantage point as the last graduate student of this eminent physicist, Gerard Hyland has produced an account that weaves the personal experiences and travails of Fröhlich with detailed discussion of the theory of dielectrics. The political upheavals in Europe during the 20th century provide a dramatic backdrop for the narrative.

Wars of the holographic world

Preskill, John

In the popular imagination, the iconic American theoretical physicist is Richard Feynman, in all his safe-cracking, bongo-thumping, woman-chasing glory. I suspect that many physicists, if asked to name a living colleague who best captures the spirit of Feynman, would give the same answer as me: Leonard Susskind. As far as I know, Susskind does not crack safes, thump bongos, or chase women, yet he shares Feynman's brash cockiness (which in Susskind's case is leavened by occasional redeeming flashes of self-deprecation) and Feynman's gift for spinning fascinating anecdotes. If you are having a group of physicists over for dinner and want to be sure to have a good time, invite Susskind.

This book is about classical mechanics. Usually `classical' calls to mind Newtonian mechanics and that is indeed where modern physics started. The bulk of the book is devoted to sections which will contain mainly categorized groups of Q&As from the web site, sort of a Best of Ask the Physicist.

Uncommon Sense - The Heretical Nature of Science

NASA Astrophysics Data System (ADS)

Cromer, Alan

1995-08-01

Most people believe that science arose as a natural end-product of our innate intelligence and curiosity, as an inevitable stage in human intellectual development. But physicist and educator Alan Cromer disputes this belief. Cromer argues that science is not the natural unfolding of human potential, but the invention of a particular culture, Greece, in a particular historical period. Indeed, far from being natural, scientific thinking goes so far against the grain of conventional human thought that if it hadn't been discovered in Greece, it might not have been discovered at all.In Uncommon Sense , Alan Cromer develops the argument that science represents a radically new and different way of thinking. Using Piaget's stages of intellectual development, he shows that conventional thinking remains mired in subjective, "egocentric" ways of looking at the world--most people even today still believe in astrology, ESP, UFOs, ghosts and other paranormal phenomena--a mode of thought that science has outgrown. He provides a fascinating explanation of why science began in Greece, contrasting the Greek practice of debate to the Judaic reliance on prophets for acquiring knowledge. Other factors, such as a maritime economy and wandering scholars (both of which prevented parochialism) and an essentially literary religion not dominated by priests, also promoted in Greece an objective, analytical way of thinking not found elsewhere in the ancient world. He examines India and China and explains why science could not develop in either country. In China, for instance, astronomy served only the state, and the private study of astronomy was forbidden. Cromer also provides a perceptive account of science in Renaissance Europe and of figures such as Copernicus, Galileo, and Newton. Along the way, Cromer touches on many intriguing topics, arguing, for instance, that much of science is essential complete; there are no new elements yet to be discovered. He debunks the vaunted SETI (Search for Extraterrestrial Intelligence) project, which costs taxpayers millions each year, showing that physical limits--such as the melting point of metal--put an absolute limit on the speed of space travel, making trips to even the nearest star all but impossible. Finally, Cromer discusses the deplorable state of science education in America and suggests several provocative innovations to improve high school education, including a radical proposal to give all students an intensive eighth and ninth year program, eliminating the last two years of high school.Uncommon Sense is an illuminating look at science, filled with provocative observations. Whether challenging Thomas Kuhn's theory of scientific revolutions, or extolling the virtues of Euclid's Elements , Alan Cromer is always insightful, outspoken, and refreshingly original.

Episodic and working memory processes show pronounced age-related decline, with other memory processes such as semantic, procedural, and metamemory less affected. Older adults tend to complain the most about prospective and retrospective memory failures. We introduce a framework for deciding how to mitigate memory decline using augmentation and substitution and discuss techniques that change the user, through mnemonics training, and change the tool or environment, by providing environmental support. We provide examples of low-tech and high-tech memory supports and discuss constraints on the utility of high-tech systems including effectiveness of devices, attitudes toward memory aids, and reliability of systems.
