The International Physics Olympiad (IPhO) is an annual physics competition for high school students. In our article, we will discuss its development and results of research among former contestants from Czechoslovakia, resp. from Czech Republic.
Five high school physics students will represent the U.S. at the 20th International Physics Olympiad, July 14-25 in Warsaw, Poland. The Olympiad has been held annually since 1967; this is the fourth year the U.S. will compete. The American Association of Physics Teachers administers the U.S. program; AGU is a principal sponsoring organization of the Olympiad, as is the American Institute of Physics.The students are Derrick Bass, North Miami Beach High School, Miami Beach, Fla.; Steven Gubser, Cherry Creek High School, Englewood, Colo.; Jason Jacobs, Baldwin Senior High School, Baldwin, N.Y.; Jessica Millar, West High School, Madison, Wise; and James Sarvis, Thomas Jefferson High School, Alexandria, Va.
Contents include the following: listings of committees, grading teams, participating and observing delegations, and sponsors; the Michelson Interferometer; the opening ceremony; social, cultural and scientific events; the closing ceremony; and award winners. The examination and its syllabus are included with histograms of the scores. The International Board is listed along with observers, student participants, and guides. Preliminary mailings are included.
photographed on the nest. We learnt about Wattles (Australia's national flower), Bottle brush trees and saw Kookaburras in the Botanic Gardens. Most of the students had time to visit the Science Museum. We were taken to Tidbinbilla Deep Space Tracking Station - in the week when Galileo's Jupiter probe was released - and Tidbinbilla Nature Reserve. We travelled across the Southern Tablelands and through dramatic mountain passes to the coast. Our students were happy with the 'cylinders falling in glycerol' experiment but not so sure that they had estimated the reduction in intensity correctly in the laser/diffraction experiment. Some of them felt that there had been less emphasis on practical work as they neared the end of their A-level courses. They would have appreciated some more preparation for this. There was a range of hospitality shown to us; receptions were held by the Deputy Chief Minister of the Australian Capital Territory and the Vice-Chancellor of Canberra University, and we were guests of the Rotary Club members in their own homes. Some students spent a day with an Australian family. The British High Commissioner took the British party out to dinner. All of this was much appreciated! Soon it was time to discuss the marking of the practical, and our students seemed to have held their positions. The formula for the medals is Gold for 90 Until the top mark was settled at an incredible 95 that they were happy with the scores we knew the results. Alan Bain and Richard Davies had tied with identical marks on each of the two papers and would receive Gold medals. They were about 19th out of the 255 students competing. The other three students were close together and gained Bronze medals, although Chris Webb was only two points away from a Silver! There was considerable discussion at the International meeting of Leaders about the mounting cost of hosting the International Physics Olympiad. The number of countries entering had increased and could potentially exceed 100

The International Olympiad on Astronomy and Astrophysics, an annual astronomy and astrophysics competition for high school students, is described. Examples of problems and solutions from the competition are also given. (Contains 3 figures.)
It is surprising, but the fact is that the International Olympiads are often only combined with the competition, whereas the intercultural communication between the representatives of different nationalities and the expanding of ideologies of young people are the general-purpose components of not only in frames of the boundaries of scientific expertise, but also such communications, the Olympiads. Worldviews meeting and collaboration are driving forces of progress and play the most important role in the development of the modern science. Armenia participates in the International Astronomical Olympiads since 1997, and in the International Olympiads on Astronomy and Astrophysics since 2013. The Armenian team has always shown high results in competitions and is actively involved in cultural activities.

The International Science Olympiad is an international intellectual olympic in which students, aging under 20 and who have not entered university, compete using their creative problem solving skills in the field of science. Many nations participate in the Olympiad with great interest, for this competition is a global youth science contest which is also used to measure national basic science levels. However in Korea, benefits for Olympiad participants were reduced because issues were risen that the Olympiad could intensify private education. This resulted in a continuous decrease in the number of applicants, bringing national competitiveness deterioration to concern. Therefore in this study, we identified the problems by analyzing the actual conditions of Olympiad participants' private education, and sought support plans to activate Olympiad participation. For this use, we conducted a survey of 367 summer school and winter school acceptees in 9 branches. 68.9% of the students were preparing for the Olympiad by private education, and the highest percentage answered that their private education expenses were an average of 3~5 million won. Olympiad preparation took up 30~50% of all private education, showing that private education greatly influences the preparing processes for the Olympiad. Meanwhile the participants perceived that in order to reduce Olympiad-related private education, the following should be implemented priority: supply of free high-quality on-line education materials, and easy access to Olympiad related information. It was also suggested that the most effective and needed education methods were school olympiad preparation classes, on-line education expansion, and special lectures and mentoring from olympiad-experienced senior representatives. Additionally, as methods to activate Olympiad participation, it was thought that award records should be allowed to be used in college applications by enabling award records into student records and special

The International Earth Science Olympiad (IESO) is the latest of the great scientific olympics. It offers high-school students from all around the world the possibility of participating in a competition in a different country every year. About 30 countries took part in the last edition of IESO in Japan. France has participated in this event for the past four years with a certain amount of success, with many students winning medals. In 2017, the IESO will take place in France for the first time in the technopole of Sophia- Antipolis, under the watchful eyes and responsibility of the " Université Côte d'Azur ". The IESO typically lasts for about a week. Each country sends a maximum of four student participants, accompanied by two mentors. Guest students and observers may also form part of the national team. Outer space, atmosphere, hydrosphere, geosphere… The Olympiad programme highlights the cross-curricular dimensions of geoscience, mainly in English. The candidates participate in a written test in every focus area of the programme as well as in several practical tests. A last activity brings candidates of different nationalities together for team fieldwork, followed by an oral presentation of their findings. The IESO is the perfect opportunity for young people to discover the culture of the host country. With this in mind, the agenda includes trips to cultural or natural sites of interest, and festive events. The participants would also get a flavour of their peers' cultures. The spirit of this competition is to promote discussion and exchange to find collective solutions to the planet's problems.

The GSJ is the main supporting organization of IYPE Japan, which is an implementation body of IYPE in Japan, serving as its secretariat. During the IYPE triennial activity, the GSJ has been supporting development of Geparks, establishment of "the Geology Day" and the Earth Science Olympiad activities with some academic societies, and has distributed geological maps with IYPE logo. The GSJ also established an outreach network "Geo-networks Tsukuba" as a local legacy of the IYPE, and has managed it with a local government, research organizations, nonprofit corporations and local media to increase geological and environmental literacy of public, especially among young people. The GSJ-AIST has also contributed internationally to IYPE by joining two international projects, OneGeology and the CCOP Book project. Geoparks in Japan are characterized by following features. The Japanese Islands and the surrounding seas are situated in the area of unique geologic features; the place where several tectonic plates meet and collide. This causes earthquakes and volcanic activities, and makes Japan one of most dynamic areas on the earth. The dynamics of the earth bring about not only geological hazards but also a lot of blessings. In August of 2009, three Geoparks, the Toya Caldera and Usu Volcano Geopark, the Itoigawa Geopark and the Unzen Volcanic Area Geopark, were accepted to join the Global Geopark Network from Japan for the first time. Since its launch in 2006, the GSJ has been playing a major role in promoting Geoparks in Japan together with Geological Society of Japan. The GSJ hosts the Japan Geopark Committee (JGC) for quality evaluation, serving as the information center of Geoparks in Japan. The Geology Day of Japan (10th of May) has been set up by the academic societies for geology in Japan and GSJ in 2007. The Geology Day is expected to provide the chances for the public to enjoy field trips and excursions and to understand the importance of geo-diversity. The Day

This research focused on the processes and physics instruction of 25 schools located in Bangkok and up-country in Thailand in order to explain why many of their students have passed the first round of the National Physics Academic Olympiads consistently. The high schools in Thailand can apply and support their students and develop their potential in physics. The development of physics professional is the cornerstone of a developing country and increase physics quality base on sciences development in the future in Thailand. The duration of collecting all data was from May 2007 to May 2009. The methodology for this research was the qualitative research method. The researchers interviewed managers, teachers and students at each school location or used semi-structured interview forms. The researchers used the Investigator Triangulation approach to check the qualitative data and the Cause and Effect Analysis approach to analyze situation factors. The results showed that in processes were include 1) enhanced the students with the Academic Olympiads to develop the capacities of students; 2) motivated the students with processes such as good instruction in physics and special privilege in continuing studies in university; and 3) tutorial systems and drill and practice systems support students into subsequent rounds. 4) Admiration activities accommodated the students continually and suitably. Most of the teaching styles used in their lectures, in both basic contents and practice, encouraged students to analyze entrance examination papers, little laboratory. While students say that" They just know that a physics laboratory is very important to study physics after they passed Olympic camp."

Social cognitive theory guided the design of a survey to investigate high school students' perceptions of factors affecting their career contemplations and beliefs regarding the influence of their participation in the international Science Olympiad on their subject interests and twenty-first century skills. In addition, gender differences in students' choice of competition category were studied. Mixed methods analysis of survey returns from 172 Olympiad participants from 31 countries showed that students' career aspirations were affected most by their teachers, personal interests, and parents, respectively. Students also indicated that they believed that their participation in the Olympiad reinforced their plan to choose a science, technology, engineering, and mathematics (STEM) major at college and assisted them in developing and improving their twenty-first century skills. Furthermore, female students' responses indicated that their project choices were less likely to be in the engineering category and more likely to be in the environment or energy categories. Findings are discussed in the light of increasing the awareness of the role and importance of Science Olympiads in STEM career choice and finding ways to attract more female students into engineering careers.

The Olympiad movement has a long history in Estonia, and the national system developed several decades ago. The first Olympiad for gifted and talented students was held in mathematics in 1950. Now there are more than 20 different fields of competition for basic school and gymnasium students. In 2005/2006, Estonian teams participated in 18…
The Korean Astronomical Society initiated the Korea Astronomy Olympiad (KAO) in 2001 and also began to participate in the international astronomy olympiad in 2002, as a means to promote astronomy among Korean high school students. To find out how successful such endeavor has been, first how partipating students regard astronomy as their career choice has been investigated. Of the students who have taken part in the international astronomy olympiads and then have entered a college afterwards in the period 2002-2014, more than 50% have chosen astronomy, physics, or earth science as their college major. In addition, when the future career choices of the KAO applicants were examined through their school records, astronomy and space science were chosen to be 44% in 2014, a significant increase from 25% in 2010. Secondly, the astronomical content of the regular Korean high school curriculum has been compared with the syllabus of international astronomy olympiads, to see how students can enhance their astronomical understanding through participating in astronomy olympiads, which would in turn contribute to their possible future career in astronomy.
The goals and history of the Mathematical Olympiads for Elementary Schools are described. Teams, levels, and gender are discussed, as well as teacher training, administration, scoring, and awards. Sample problems are included. (MNS)

In the fall of 1991, approximately 8000 Junior and Senior High Schools from 39 states in the country registered one or more teams with the National Science Olympiad Headquarters, and started working their way towards the Science Olympiad National Tournament, which was held at Auburn University, Alabama on May 15 and 16, 1992. Teams that made it to the Science Olympiad National Tournament had to compete at the regional (e.g., Alabama had five regional tournaments) and state levels. In most cases a team had to be number one in the state in order to make it into the National Tournament. Since the decision was made to invite 50 teams from each division (division B is Junior High and division C is Senior High), for each state that did not participate, another state could send two teams. The selection of states that could send a second team was based on statewide registration with the National Headquarters.

The National Science Olympiad is one of the United States' largest science competitions, reaching over 6,000 schools in 48 states. The Olympiad includes a wide variety of events, stretching a full range of potential future STEM careers, from biological sciences to engineering to earth and space sciences. The Astronomy event has been a mainstay at the high school level for well over a decade, and nominally focuses on aspects of stellar evolution. For the 2014-2015 competition season, the event focus was aligned to include exoplanet discovery and characterization along with star formation. Teams studied both the qualitative features of exoplanets and exoplanetary systems and the quantitative aspects behind their discovery and characterization, including basic calculations with the transit and radial velocity methods. Students were also expected to have a qualitative understanding of stellar evolution and understand the differences between classes of young stars including T Tauri and FU Orionis variables, and Herbig Ae/Be stars. Based on the successes of this event topic, we are continuing this event into the 2015-2016 academic year. The key modification is the selection of new exoplanetary systems for students to research. We welcome feedback from the community on how to improve the event and the related educational resources that are created for Science Olympiad students and coaches. We also encourage any interested community members to contact your regional or state Science Olympiad tournament directors and volunteer to organize competitions and supervise events locally.

Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in

Science education and literacy, along with a focus on the other STEM fields, have been a center of attention on the global scale for decades. The 1950's race to space is often considered the starting point. Through the years, the attention has spread to highlight the United States' scientific literacy rankings on international testing. The ever-expanding global economy and global workplace make the need for literacy in the STEM fields a necessity. Science and academic competitions are worthy of study to determine the overall and specific positive and negative aspects of their incorporation in students' educational experiences. Science Olympiad is a national science and engineering competition that engages thousands of students each year. The purpose of this study was to analyze the perceptions of Science Olympiad participants, in terms of science learning and interest, 21st century skills and abilities, perceived influence on careers, and the overall benefits of being involved in Science Olympiad. The study sought to determine if there were any differences of perception when gender was viewed as a factor. Data was acquired through the Science Olympiad survey database. It consisted of 635 usable surveys, split evenly between males and females. This study employed a mixed methods analysis. The qualitative data allowed the individual perceptions of the respondents to be highlighted and acknowledged, while the quantitative data allowed generalizations to be identified. The qualitative and quantitative data clearly showed that Science Olympiad had an impact on the career choices of participants. The qualitative data showed that participants gained an increased level of learning and interest in science and STEM areas, 21st century skills, and overall positive benefits as a result of being involved. The qualitative data was almost exclusively positive. The quantitative data however, did not capture the significance of each researched category that the qualitative

This editorial opens the second special section on physics competitions in European Journal of Physics. In the first section last year, we asked for feedback on the idea of such a section and on the content of the articles. We received no answer whatsoever, which can be interpreted in two ways: the section is not interesting enough to raise motivation for feedback, or the reader is satisfied. Having no indication which scenario is the correct one, we are optimistic and favour the second. The section at hand contains three articles. Again, as last year, the organizer of the annual Olympiad reports on tasks and outcomes of this competition. The Olympiad took place in Merida, Mexico, and was by far the largest event with 316 contestants from 68 countries. Again, the predominance of Asian/Chinese students was manifest, showing how serious the training is taken by both their authorities and students. Unfortunately, the winners of the last International Young Physicists' Tournament (IYPT), the team from Korea, did not accept the offer to report on their prize-winning contribution. We are thankful that two students from Austria, who achieved second place with their team, took over and reported on the task which they presented in the finals of the competition. It connects the fields of sport and physics and explains a special move in skateboarding. The third contribution introduces a different competition, 'International Conference of Young Scientists'. On one hand, as in the Olympiad, it addresses individuals, not teams. On the other, as in the IYPT, students have several months to prepare and also the quality of the presentation is an important element of the judgment. In fact, this competition comes closer to real scientific research compared to the other events. Finally and again, we hope that this section will serve several purposes: To show the competitions as a very important tool in the support of gifted students. To raise awareness amongst university teachers, and

Science Olympiad is one of the nation’s largest secondary school science competitions, reaching over 240,000 students on more than 6,000 teams. The competition covers various aspects of science and technology, exposing students to a variety of career options in STEM. 9 of Science Olympiad’s 46 events (with 23 for both middle and high school) have a focus on Earth and Space Science, including process skills and knowledge of a variety of subjects, including: Astrophysics, Planetary Sciences, Oceanography, Meteorology, Remote Sensing, and Geologic Mapping, among others. The Astronomy event is held for students from 9th - 12th grade, and covers topics based upon stellar evolution and/or galactic astronomy. For the 2014-2015 competition season, Astronomy will focus on star formation and exoplanets in concert with stellar evolution, bringing recent and groundbreaking research to light for young potential astronomers and planetary scientists. The event tests students on their “understanding of the basic concepts of mathematics and physics relating to stellar evolution and star and planet formation,” including qualitative responses, DS9 image analysis, and quantitative problem solving. We invite any members of the exoplanet and star formation communities that are interested in developing event materials to contact the National event supervisors, Donna Young (firstname.lastname@example.org) and Tad Komacek (email@example.com). We also encourage you to contact your local regional or state Science Olympiad tournament directors to help supervise events and run competitions in your area.
This May, five seniors from the North Carolina School of Science and Mathematics and their adult leaders, Hugh Haskell and Chuck Britton, were the first US team to compete in the International Young Physicists Tournament (IYPT), which took place in Vienna, Austria. They challenged and were challenged by eighteen similar teams from sixteen other countries. The IYPT differs from the Physics Olympiad, which is an examination, whereas the Tournament is a debate on the solution of seventeen open-ended problems published in October, on the IYPT website

International tests on competences, such as TIMSS or PISA, and knowledge of young students have revealed low average scores in many countries, often unexpectedly. One effective measure to increase the average standard of a population is to bring the last third of the group to a higher level. Therefore, many nations put some effort into this activity. This brings the danger that not enough attention is paid to students at the other end, those who are talented. Indeed, it is a very difficult task for a teacher to support the less able and at the same time challenge the gifted students, to lead them to the limits of their abilities and provide for a smooth transition to university study. Physics competitions have been proven to fulfil these last demands to a large degree, and therefore are an important additional and, to some extent, complementary tool for the promotion of talented students. This third special section on physics competitions in European Journal of Physics contains three papers, each dealing with a different form of science contest. The first continues the series of presentations of tasks performed at the International Young Physicists' Tournament, which was held in Vienna in 2011. First place went to the team from Singapore, and they have put their investigation on vertical oscillations of coupled magnets into written form (not required by the tournament, where an oral presentation and a defence and discussion are the central aspects). Their paper shows how rich in physics this problem is, and what level of solutions high-school students can already achieve. Sadly, those responsible for the organization of last year's International Physics Olympiad did not provide us with a report on this competition. This is unfortunate, since the Olympiad in Zagreb was very successful and, in particular, the experimental tasks were creative and demanding. Very similar to the aims and the execution of the Physics Olympiad is the International Olympiad on Astronomy

The present study examines the performance of academically talented students (i.e., those who received awards in Olympiads, the international competitions for gifted students in science or mathematics) in medical school. The goal is to investigate whether students exceptionally talented in science and mathematics excel in medical school. A retrospective analysis of 13 cohorts of medical students (N = 475) was conducted to compare learning outcomes of academically talented students (ATS) with their peers in terms of their grade point averages (GPAs) and national licensing exam (KMLE) scores. ATS outperformed their peers in total GPAs (p < .001); yet there was a statistical trend of gradually diminishing performance gap between the groups as they progressed into the later years of the program. KMLE scores were comparable between the groups (p = .89). In addition, there was no significant difference in GPAs and KLME scores among ATS regardless of their areas of excellence. Academic merit alone is not a strong predictor of success in medical school, even among those with exceptional talent. Better understanding of nonacademic factors associated with medical school performance is warranted to improve our selection processes and to better help academically talented students succeed in medical school.

The 1^st International Union of Pure and Applied Physics (IUPAP) Conference on Women in Physics, held in 2002 in Paris, France, highlighted a number of issues facing women physicists around the world. A second conference was held in May 2005 in Rio de Janeiro, Brazil, with the goal of examining the progress made since the last conference and also to provide an opportunity for the delegates to present their research, both physics research and gender-related research, and to make contacts for future collaborations. The conference was attended by 145 delegates from 42 countries, including a very diverse delegation of 22 women and men from the U.S. The conference was organized by the Working Group on Women in Physics of IUPAP, which is charged with making recommendations to IUPAP on how to attract, retain, and increase the participation of women in physics at all levels. The conference included a round table discussion on ``Research Funding and Women in Physics,'' several plenary talks, a poster session on women in physics in each country, a poster session on research by individual delegates, and discussion groups on six topics including attracting girls into physics, launching a successful career, getting women into leadership, improving the institutional climate, learning from regional differences, and balancing family and career. Conference proceedings have been published that include research abstracts, summaries from the discussion groups, articles on the plenary talks, and papers from each country on the status of women in physics in their country (proceedings can be found at http://proceedings.aip.org/proceedings/confproceed/795.jsp). This talk will discuss the U. S. delegation and their country paper on the situation for women in physics in the U.S. as well as highlights from the information presented by the delegates from other nations. The outcomes of the 2002 conference will be described briefly and then the signs of progress noted in 2005 will be summarized.

Biometrics is described as the science of identifying people based on physical characteristics such as their fingerprints, facial features, hand geometry, iris patterns, palm prints, or speech recognition. Notably, all of these physical characteristics are visible or detectable from the exterior of the body. These external characteristics can be lifted, photographed, copied or recorded for unauthorized access to a biometric system. Individual humans are unique internally, however, just as they are unique externally. New biometric modalities have been developed which identify people based on their unique internal characteristics. For example, "BoneprintsTM" use acoustic fields to scan the unique bone density pattern of a thumb pressed on a small acoustic sensor. Thanks to advances in piezoelectric materials the acoustic sensor can be placed in virtually any device such as a steering wheel, door handle, or keyboard. Similarly, "Imp-PrintsTM" measure the electrical impedance patterns of a hand to identify or verify a person's identity. Small impedance sensors can be easily embedded in devices such as smart cards, handles, or wall mounts. These internal biometric modalities rely on physical characteristics which are not visible or photographable, providing an added level of security. In addition, both the acoustic and impedance methods can be combined with physiologic measurements such as acoustic Doppler or impedance plethysmography, respectively. Added verification that the biometric pattern came from a living person can be obtained. These new biometric modalities have the potential to allay user concerns over protection of privacy, while providing a higher level of security.*
Invited Papers: The Physics of Hot Plasmas During the last decade a dramatic evolution of plasma physics has occurred. Not only have gigantic fusion plasma machines been planned, and are now being built, and elaborate spaceships and antenna systems been constructed to explore remote parts of the cosmos; new observations have revealed fascinating structures in space, ranging from pulsar plasmas under extreme conditions in very strong magnetic fields to large-scale magnetic field and electric current systems in cosmic plasmas. X-rays from very distant sources as well as radio-waves from the plasma in the magnetosphere and in the Aurora have recently been studied with new observational techniques. Ingenious laboratory experiments are continuously being carried out to exploit new fundamental processes in plasmas. These are of great interest for the basic understanding of plasmas and also have immediate consequences for applications, like plasma heating and diagnostics. The theoretical description of new plasma phenomena, and of the plasma state in general poses challenging problems, particularly in situations where high concentration of energy is located in the plasmas. Nonlinear wave analysis and turbulence theory have accordingly been extensively developed to describe in particular the collective plasma phenomena. New concepts have been envisaged like plasma solitons, which may be thought of as excitations of local concentrations of longitudinal plasma waves which turn out to be particularly stable. More and more sophisticated structures of nonlinear nature are being revealed by means of high capacity computer facilities. Simulation experiments allow for studies of chaotic behaviour of plasma particles. Related fields of activity form new trends in the development of plasma theory. The programme of the 1982 International Conference on Plasma Physics, which was held in Göteborg, Sweden, stressed the role of the Physics of Hot Plasmas. Studies of such plasmas are
In the frame of the fortieth anniversary celebration of the Universidad Autónoma Metropolitana and the Physics Engineering career, the Division of Basic Science and Engineering and its Departments organized the "VII International Congress of Physics Engineering". The Congress was held from 24 to 28 November 2014 in Mexico City, Mexico. This congress is the first of its type in Latin America, and because of its international character, it gathers experts on physics engineering from Mexico and all over the globe. Since 1999, this event has shown research, articles, projects, technological developments and vanguard scientists. These activities aim to spread, promote, and share the knowledge of Physics Engineering. The topics of the Congress were: • Renewable energies engineering • Materials technology • Nanotechnology • Medical physics • Educational physics engineering • Nuclear engineering • High precision instrumentation • Atmospheric physics • Optical engineering • Physics history • Acoustics This event integrates lectures on top trending topics with pre-congress workshops, which are given by recognized scientists with an outstanding academic record.

It was a pleasure to welcome all delegates and accompanying persons to Adelaide for the 26th International Conference in Nuclear Physics, INPC2016. As the major meeting in our field, it was a wonderful opportunity to catch up with colleagues from around the world, learn about the very latest developments and share ideas. We were grateful for the support of the Commission on Nuclear Physics, C12, of the International Union of Pure and Applied Physics (IUPAP), which chose Adelaide to host this meeting. We were also honoured that the President of IUPAP, Prof. Bruce McKellar was present at the meeting to welcome delegates and participate in the proceedings. We acknowledge the financial support for the conference which was made available by a number of organisations. We were especially grateful to the major sponsors, the Adelaide Convention Bureau, the University of Adelaide, the Australian National University and ANSTO, as well as IUPAP, the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP) and several of the world's major nuclear physics laboratories, BNL, GSI, JLab and TRIUMF. As a result of these contributions we were able to offer support to attend the conference to more than 50 international students. Not only did we have a superb scientific program but, consistent with IUPAP guidelines, more than 40% of the invited plenary talks were presented by women. In order to reach out to the local community, Cynthia Keppel (from JLab) presented a public lecture on Hadron Beam Therapy on Tuesday evening, September 13th. As presenting a talk is now often a condition for financial support to attend an international conference, there were 11 simultaneous parallel sessions with more than 350 presentations. We are especially grateful to the International Advisory Committee, the Program Committee and the Conveners whose advice and hard work made it possible for all this to come together. I would also like to acknowledge the work of the Local Organising

We report on the organization and realization of the Joint International Physics Summer School - Optics" devoted to High-School students. The idea of the School is to teach Physics through high-level experimental activities, suitably supported by introductory lectures and complemented by data analysis. The School is also open to the participation of a number of teachers, as an opportunity of refreshing their knowledge and increasing their experimental skills. Students and teachers are directly involved in the experimental activities. The aim of the activity is to stimulate students curiosity and interest and help them decide whether a future job career in Science could be suited for them. The School is organized in two weeks: the first in June-July in Como (Italy) at the Department of Science and High Technology and the second at the end of August in Olomouc (Czech Republic) at the Joint Laboratory of Optics. Two editions of the Summer School took place in 2013 and 2014 (overall 40 students and 3 teachers from Italy, 9 students from Czech Republic) and the third one will be in 2015. The first week of the School is devoted to introductory lectures (theoretical and experimental) to consolidate students' and teachers' knowledge of basic optics. The second week is devoted to several advanced experiments in linear, nonlinear, classical and quantum optics, performed in research laboratories. During the last day of the School, students are required to give a presentation of the results obtained during the experimental sessions.

1. Physics competitions: aims and realizations One aim of physics competitions is to increase the interest of young students, primarily at upper secondary level, to physics and natural sciences in general. A competition has motivational aspects known usually from sports events or games—comparing one's own ability with others, of course with the desire to be better and to win. If competitions reach nationwide and even international levels, additional stimulation is created. Competitions provide greatest attraction to possible winners, to the group of gifted people in a particular field. This implies that science contests are excellent tools for the promotion of talented students. Traditional teaching has been shown to have problems in supporting this group of students. Very often teachers are overstretched with the demands of teaching both low- and high-level students. Extracurricular activities are therefore a good chance to relieve the teacher, and to give talented students the opportunity for appropriate training and challenge. The competitions, however, have a broader impact and address more young people than one might guess from the statements above. Training courses and selection at school level give a larger group of students extra and, to some extent, complimentary education in physics. The degree of complexity of the tasks corresponds very often to the standards of the next level of education in the school system. Interestingly, many physics competitions have their origin in countries beyond the former Iron Curtain. They started as regional and national tournaments, were joined by neighbouring countries and have grown, in some cases, to events with participants from more than 80 countries. Although the features mentioned above are common to the different competitions, there are distinct differences between them . The International Physics Olympiad (IPhO) is the oldest international physics competition for students at upper secondary level . It dates

Every year, hundreds of thousands of students and teachers from all over the country take part in the Brazilian Olympiad of Astronomy and Astronautics (OBA). This has the aim of both spreading astronomy and astronautics-related concepts and training teachers about these topics. After being marked some of the exams are sent by participant schools to the Organizing Committee to select candidates for the international competition. The OBA exam archive thereby offers an unique opportunity to evaluate the teaching of astronomy in Brazil in relation to school level and content, as well as over time. Understanding the misconceptions unraveled by the exams is of utmost importance to planning successful outreach activities. In this talk I will present how the analysis of the 2013 OBA event helped the Museum of Astronomy and Related Sciences to develop an astronomy education kit aimed at teachers and how this cooperation between an academic institution and schools is helping educators in their pedagogical practice to teach astronomy in the classroom.

This session organized by the APS Committee on the Status of Women in Physics will open with a brief memorial to Dr. Chien-Shung Wu, who died on February 16, 1997. It will continue with an exploration of the challenges faced by women in physics in various parts of the world. We will hear both personal and statistical pictures of the experiences of women in physics in Japan and Canada. The presentations from the two countries (approximately 20 min. each) will be followed by an open forum in which questions from the audience will be invited. "Chien-Shung Wu: In Memoriam" Speaker: Noemie Benczer-Koller. Dr. Chien-Shung Wu and her 1957 experiment on parity non-conservation shattered what was thought to be a fundamental law of physics. Her contributions to women in physics (including her election in 1975 to the APS Presidency) will be briefly recalled. The Japanese Perspective "A Female Physicist in Japan" Fumiko Yonezawa (President, Physical Society of Japan). Dr. Yonazawa will share her experiences as a female physicist in Japan, and describe the path she has taken to leadership in her professional society. The Canadian Perspective "Women in Physics in Canada: A Physics Graduate and Faculty Survey" Janis McKenna (Univ. of British Columbia). Dr. McKenna will present the results of a 1995 CAP-sponsored survey of women faculty and graduates in physics in Canada, which concluded that the situation for women in physics in Canada is very similar to that in the U.S. (only 5% of faculty members are women), and not as progressive as the situation in several European countries. "Physics on the Border: The 'Two-Body Problem' for Canadian Physicists" Ann McMillan (Atmospheric Environment Service). Dr. McMillan will describe how the geographic distribution of Canadian universities and research facilities poses unique problems for physicists balancing two careers in one family. She will discuss the particular challenges faced by female physicists, and the institutional responses to

Background Regular physical activity plays an important role in the amelioration of several mental health disorders; however, its relationship with burnout has not yet been clarified. Objective To determine the association between achievement of national physical activity guidelines and burnout in internal medicine resident physicians. Methods A Web-based survey of internal medicine resident physicians at the University of Minnesota and Hennepin County Medical Center was conducted from September to October 2012. Survey measures included the Maslach Burnout Inventory-Human Services Survey and the International Physical Activity Questionnaire. Results Of 149 eligible residents, 76 (51.0%) completed surveys, which were used in the analysis. Burnout prevalence, determined by the Maslach Burnout Inventory, was 53.9% (41 of 76). Prevalence of failure to achieve US Department of Health and Human Services physical activity guidelines was 40.8% (31 of 76), and 78.9% (60 of 76) of residents reported that their level of physical activity has decreased since they began medical training. Residents who were able to meet physical activity guidelines were less likely to be burned out than their fellow residents (OR, 0.38, 95% CI 0.147–0.99). Conclusions Among internal medicine resident physicians, achievement of national physical activity guidelines appears to be inversely associated with burnout. Given the high national prevalence of burnout and inactivity, additional investigation of this relationship appears warranted. PMID:26140116

Traditional department-based surgical interest groups in Russian medical schools are useful tools for student-based selection of specialty training. They also form a nucleus for initiating research activities among undergraduate students. In Russia, the Departments of Topographical Anatomy and Operative Surgery play an important role in initiating student-led research and providing learners with advanced, practical surgical skills. In tandem with department-led activities, student surgical interest groups prepare learners through surgical competitions, known as "Surgical Olympiads," which have been conducted in many Russian centers on a regular basis since 1988. Surgical Olympiads stimulate student interest in the development of surgical skills before graduation and encourage students to choose surgery as their postgraduate specialty. Many of the participants in these surgical Olympiads have become highly qualified specialists in general surgery, orthopedic surgery, neurosurgery, urology, gynecology, and emergency medicine. The present article emphasizes the role of student interest groups and surgical Olympiads in clinical anatomical and surgical undergraduate training in Russia. © 2015 American Association of Anatomists.

Aims: To examine the dimensionality, internal consistency, and construct validity of a new physical workload questionnaire in employees with musculoskeletal complaints. Methods: Factor analysis was applied to the responses in three study populations with musculoskeletal disorders (n = 406, 300, and 557) on 26 items related to physical workload. The internal consistency of the resulting subscales was examined. It was hypothesised that physical workload would vary among different occupational groups. The occupations of all subjects were classified into four groups on the basis of expected workload (heavy physical load; long lasting postures and repetitive movements; both; no physical load). Construct validity of the subscales created was tested by comparing the subscale scores among these occupational groups. Results: The pattern of the factor loadings of items was almost identical for the three study populations. Two interpretable factors were found: items related to heavy physical workload loaded highly on the first factor, and items related to static postures or repetitive work loaded highly on the second factor. The first constructed subscale "heavy physical work" had a Cronbach's α of 0.92 to 0.93 and the second subscale "long lasting postures and repetitive movements", of 0.86 to 0.87. Six of eight hypotheses regarding the construct validity of the subscales were confirmed. Conclusions: The results support the internal structure, internal consistency, and validity of the new physical workload questionnaire. Testing this questionnaire in non-symptomatic employees and comparing its performance with objective assessments of physical workload are important next steps in the validation process. PMID:15550603
In this paper, I try to decipher the role of internal symmetries in the ontological maze of particle physics. The relationship between internal symmetries and laws of nature is discussed within the framework of ;Platonic realism.; The notion of physical ;structure; is introduced as representing a deeper ontological layer behind the observable world. I argue that an internal symmetry is a structure encompassing laws of nature. The application of internal symmetry groups to particle physics came about in two revolutionary steps. The first was the introduction of the internal symmetries of hadrons in the early 1960s. These global and approximate symmetries served as means of bypassing the dynamics. I argue that the realist could interpret these symmetries as ontologically prior to the hadrons. The second step was the gauge revolution in the 1970s, where symmetries became local and exact and were integrated with the dynamics. I argue that the symmetries of the second generation are fundamental in the following two respects: (1) According to the so-called ;gauge argument,; gauge symmetry dictates the existence of gauge bosons, which determine the nature of the forces. This view, which has been recently criticized by some philosophers, is widely accepted in particle physics at least as a heuristic principle. (2) In view of grand unified theories, the new symmetries can be interpreted as ontologically prior to baryon matter.

This special issue of Physica Scripta contains papers presented at the 1st International Meeting on Applied Physics (APHYS-2003), held in Badajoz (Spain), from 13th to 18th October 2003, and more specifically, selected papers presented during the conference sessions mainly on Applied Optics, Laser Physics, Ultrafast Phenomena, Optical Materials, Semiconductor Materials and Devices, Optoelectronics, Quantum Electronics and Applied Solid State Physics-Chemistry. APHYS-2003 was born as an attempt to create a new international forum on Applied Physics in Europe. Since Applied Physics is not really a branch of Physics, but the application of all the branches of Physics to the broad realms of practical problems in Science, Engineering and Industry, this conference was a truly multi and inter-disciplinary event. The organizers called for papers relating Physics with other sciences such as Biology, Chemistry, Information Science, Medicine, etc, or relating different Physics areas, and aimed at solving practical problems. In other words, the Conference was specifically interested in reports applying the techniques, the training, and the culture of Physics to research areas usually associated with other scientific and engineering disciplines. It was extremely rewarding that over 800 researchers, from over 65 countries, attended the conference, where more than 1000 research papers were presented. We feel really proud of this excellent response obtained (in number and quality), for this first edition of the conference.

The Third International Workshop & Summer School on Plasma Physics (IWSSPP'08) organized by St Kliment Ohridsky University of Sofia, with co-organizers TCPA Foundation, Association EURATOM/IRNRE, The Union of the Physicists in Bulgaria, and the Bulgarian Academy of Sciences was held in Kiten, Bulgaria, at the Black Sea Coast, from 30 June to 5 July 2008. A Special Session on Plasmas for Environmental Issues was co-organised by the Institute of Plasmas and Nuclear Fusion, Lisbon, Portugal and the Laboratory of Plasmas and Energy Conversion, University of Toulouse, France. That puts the beginning of a series in Workshops on Plasmas for Environmental Issues, now as a satellite meeting of the European Physical Society Conference on Plasma Physics. As the previous issues of this scientific meeting (IWSSPP'05, J. Phys.: Conf. Series 44 (2006) and IWSSPP'06, J. Phys.: Conf. Series 63 (2007)), its aim was to stimulate the creation and support of a new generation of young scientists for further development of plasma physics fundamentals and applications, as well as to ensure an interdisciplinary exchange of views and initiate possible collaborations by bringing together scientists from various branches of plasma physics. This volume of Journal of Physics: Conference Series includes 38 papers (invited lectures, contributed talks and posters) devoted to various branches of plasma physics, among them fusion plasma and materials, dc and microwave discharge modelling, transport phenomena in gas discharge plasmas, plasma diagnostics, cross sections and rate constants of elementary processes, material processing, plasma-chemistry and technology. Some of them have been presented by internationally known and recognized specialists in their fields; others are MSc or PhD students' first steps in science. In both cases, we believe they will raise readers' interest. We would like to thank the members of both the International Advisory Committee and the Local Organizing Committee, the

This study investigated the multigenerational impact of mothers' own exposure to physical maltreatment on internalizing symptoms in her child after accounting for her parenting practices, depression, and the child's own exposure to stressful life events. Children ( n = 101, ages 5-16), predominantly African American, were recruited into this cross sectional study using ethnographic mapping and targeted sampling for high-risk neighborhoods. Mothers reported retrospectively on their own exposure to physical maltreatment in childhood, their parenting practices, as well as current depressive symptoms. Maternal report of her child's exposure to stressful life events and child behavior was also collected. Maternal childhood exposure to physical maltreatment was significantly associated with her child's internalizing symptoms ( p = .004); this effect remained after accounting for child sex, maternal depressive symptoms, harsh parenting practices, and the child's own exposure to stressful life events. Formal tests of mediation through these pathways were non-significant. Findings suggest mothers' experience of childhood maltreatment contributes uniquely to children's internalizing symptoms, potentially through previously uncharacterized pathways. Examination of additional behavioral, psychosocial and biological pathways may help better describe the multi-generational effects of child maltreatment.

The underrepresentation of women among physicists around the world, especially in leadership positions, has broad implications for industries and government agencies with a strong need for a technologically educated workforce. The dearth of women physicists in academia exacerbates the situation in that female students lack exposure to successful women in the field. Three years ago, an international group of women met for a round table discussion at the First IUPAP International Conference on Women in Physics and discussed the importance of having women in leadership positions. They shared their experiences and successes, and drew up and reported a set of recommendations addressing the preparation of women for leadership, the selection process, and the responsibilities of institutions. They acknowledged that implementation of their recommendations would differ among countries. At the Second IUPAP International Conference on Women in Physics an international group of women met again to review, revise, and move forward on revamped recommendations from the first conference. This is a report on the new set of revamped recommendations, which address why women should be in leadership positions, goal setting, best practices, commitments, and follow-up actions for the attendees of the second conference.
The Australian particle physics community was honoured to host the 36th ICHEP conference in 2012 in Melbourne. This conference has long been the reference event for our international community. The announcement of the discovery of the Higgs boson at the LHC was a major highlight, with huge international press coverage. ICHEP2012 was described by CERN Director-General, Professor Rolf Heuer, as a landmark conference for our field. In additional to the Higgs announcement, important results from neutrino physics, from flavour physics, and from physics beyond the standard model also provided great interest. There were also updates on key accelerator developments such as the new B-factories, plans for the LHC upgrade, neutrino facilities and associated detector developments. ICHEP2012 exceeded the promise expected of the key conference for our field, and really did provide a reference point for the future. Many thanks to the contribution reviewers: Andy Bakich, Csaba Balazs, Nicole Bell, Catherine Buchanan, Will Crump, Cameron Cuthbert, Ben Farmer, Sudhir Gupta, Elliot Hutchison, Paul Jackson, Geng-Yuan Jeng, Archil Kobakhidze, Doyoun Kim, Tong Li, Antonio Limosani (Head Editor), Kristian McDonald, Nikhul Patel, Aldo Saavedra, Mark Scarcella, Geoff Taylor, Ian Watson, Graham White, Tony Williams and Bruce Yabsley.

Japanese social studies consist of three fields. That's geography, history and civics. About geographical studies in Japan, it has a lot of contents of human geography and has little contents of natural geography. I think that Japanese social studies teachers should teach more natural geography contents for ESD. There is a fieldwork lesson in geographical studies in Japan. This is the educational activity by which body and head were used. But in fact, fieldwork lessons are not performed in many Japanese junior high schools. I was a leader of iGeo2012 (in Germany). iGeo is held by three tests; Multimedia tests, Writing tests and Fieldwork tests. The test is included of a lot of contents of natural geography. And there are two skills that students acquire through the fieldwork test in iGeo. One is a map making skill, the other is decision making skill. Japanese students need more knowledge of natural geography. And those are not enough skills for Japanese students. So I did a fieldwork lesson based on iGeo's fieldwork test. The fieldwork lesson was performed around the school. It was also performed under the point of natural geography. After the lessons, students could improve map making skill. Because a lot of maps made by students in this lesson got prize of map contest in Japan. Some maps were included the view of natural geography.

[This paper is part of the Focused Collection on Gender in Physics.] We have investigated gender differences in performance over the past eight years on the Australian Science Olympiad Exam (ASOE) for physics, which is taken by nearly 1000 high school students each year. The ASOE, run by Australian Science Innovations (ASI), is the initial stage of the process of selection of teams to represent Australia at the Asian and International Physics Olympiads. Students taking the exam are generally in their penultimate year of school and selected by teachers as being high performing in physics. Together with the overall differences in facility, we have investigated how the content and presentation of multiple-choice questions (MCQs) affects the particular answers selected by male and female students. Differences in the patterns of responses by male and female students indicate that males and females might be modeling situations in different ways. Some strong patterns were found in the gender gaps when the questions were categorized in five broad dimensions: content, process required, difficulty, presentation, and context. Almost all questions saw male students performing better, although gender differences were relatively small for questions with a more abstract context. Male students performed significantly better on most questions with a concrete context, although notable exceptions were found, including two such questions where female students performed better. Other categories that showed consistently large gaps favoring male students include questions with projectile motion and other two-dimensional motion or forces content, and processes involving interpreting diagrams. Our results have important implications, suggesting that we should be able to reduce the gender gaps in performance on MCQ tests by changing the way information is presented and setting questions in contexts that are less likely to favor males over females. This is important as MCQ tests are

Although some tests for clinical reasoning assessment are now available, the theories of medical expertise have not played a major role in this filed. In this paper, illness script theory was chose as a theoretical framework and contemporary clinical reasoning tests were put together based on this theoretical model. This paper is a qualitative study performed with an action research approach. This style of research is performed in a context where authorities focus on promoting their organizations' performance and is carried out in the form of teamwork called participatory research. Results are presented in four parts as basic concepts, clinical reasoning assessment, test framework, and scoring. we concluded that no single test could thoroughly assess clinical reasoning competency, and therefore a battery of clinical reasoning tests is needed. This battery should cover all three parts of clinical reasoning process: script activation, selection and verification. In addition, not only both analytical and non-analytical reasoning, but also both diagnostic and management reasoning should evenly take into consideration in this battery. This paper explains the process of designing and implementing the battery of clinical reasoning in the Olympiad for medical sciences students through an action research.

The International Nuclear Physics Conference 2010 (INPC 2010) was held from 4-9 July in Vancouver, Canada, hosted by TRIUMF, the Canadian National Laboratory for Particle and Nuclear Physics. The INPC is the main conference in the field of nuclear physics, endorsed and supported by IUPAP (International Union for Pure and Applied Physics) and held every three years. This year's conference was the 25th in the series and attracted over 750 delegates (150 graduate students) from 43 countries. The conference's hallmark is its breadth in nuclear physics; topics included structure, reactions, astrophysics, hadronic structure, hadrons in nuclei, hot and dense QCD, new accelerators and underground nuclear physics facilities, neutrinos and nuclei, and applications and interdisciplinary research. The conference started with a public lecture 'An Atom from Vancouver' by L Krauss (Arizona), who gave a broad perspective on how nuclear physics is key to a deeper understanding of how the Universe was formed and the birth, life, and death of stars. The conference opened its scientific plenary program with a talk by P Braun-Munzinger (GSI/EMMI Darmstadt) who highlighted the progress that has been made since the last conference in Tokyo 2007. The presentation showcased theoretical and experimental examples from around the world. All topics were well represented by plenary sessions and well attended afternoon parallel sessions where over 250 invited and contributed talks were presented, in addition to over 380 poster presentations. The poster sessions were among the liveliest, with high participation and animated discussions from graduate students and post-doctoral fellows. Many opportunities were found to connect to fellow nuclear physicists across the globe and, particularly for conferences like the INPC which span an entire field, many unexpected links exist, often leading to new discussions or collaborations. Among the scientific highlights were the presentations in the fields of
A nascent idea in the numerical cognition literature--the analogical hypothesis (Pinel, Piazza, Bihan, & Dehaene, 2004)--assumes a common noisy code for the representation of symbolic (e.g., numerals) and nonsymbolic (e.g., numerosity, physical size, luminance) magnitudes. The present work subjected this assumption to various tests from the perspective of General Recognition Theory (GRT; Ashby &Townsend, 1986)--a multidimensional extension of Signal Detection Theory (Green & Swets, 1966). The GRT was applied to the dimensions of numerical magnitude and physical size with the following goals: (a) characterizing the internal representation of these dimensions in the psychological space, and (b) assessing various types of (in)dependence and separability governing the perception of these dimensions. The results revealed various violations of independence and separability with Stroop incongruent, but not with Stroop congruent stimuli. The outcome suggests that there are deep differences in architecture between Stroop congruent and incongruent stimuli that reach well beyond the semantic relationship involved.
The French particle physics community is particularly proud to have been selected to host the 35th ICHEP conference in 2010 in Paris. This conference is the focal point of all our field since more than fifty years and is the reference event where all important results in particle physics cosmology and astroparticles are presented and discussed. This alone suffices to make this event very important. But in 2010, a coincidence of exceptional events will make this conference even more attractive! What is then so special about ICHEP 2010 conference? It will be the first ICHEP conference where physics results obtained at the LHC will be presented! New results about the elusive Higgs boson, or signals of physics beyond the standard model might therefore be announced at this conference! Major discoveries in other domains such as gravitational waves, neutrino telescopes, neutrino oscillations, dark matter or in the flavour sector are also possible, just to name a few. In addition , 2010 will be an important date to shape up the future of our field. Several major projects will present the status of their Conceptual or Engineering Design Reports during the conference. The International Linear Collider (ILC) Global Design Effort team will present the report corresponding to the end of their Technical Design Phase 1. The Compact Linear Collider (CLIC) will also report on its Conceptual Design Report. Other major projects such as Super B factories will also be presented. These reports together with LHC physics results will form the basis for key political decisions needed to be taken in the years to come. In summary, there can be no doubt that Paris is the place to be in summer 2010 for anyone interested in High Energy Physics and we will make every effort to make your stay as interesting and enjoyable as possible.

A critical step in self-motion perception and spatial awareness is the integration of motion cues from multiple sensory organs that individually do not provide an accurate representation of the physical world. One of the best-studied sensory ambiguities is found in visual processing, and arises because of the inherent uncertainty in detecting the motion direction of an untextured contour moving within a small aperture. A similar sensory ambiguity arises in identifying the actual motion associated with linear accelerations sensed by the otolith organs in the inner ear. These internal linear accelerometers respond identically during translational motion (for example, running forward) and gravitational accelerations experienced as we reorient the head relative to gravity (that is, head tilt). Using new stimulus combinations, we identify here cerebellar and brainstem motion-sensitive neurons that compute a solution to the inertial motion detection problem. We show that the firing rates of these populations of neurons reflect the computations necessary to construct an internal model representation of the physical equations of motion.

The International Solar-Terrestrial Physics Program (ISTP) is a multispacecraft, multinational program whose objective is to promote further understanding of the Earth's complex plasma environment. Extensive data sharing and data analysis will be needed to ensure the success of the overall ISTP program. For this reason, there has been a special emphasis on data standards throughout ISTP. One of the key tools will be the common data format (CDF), developed, maintained, and evolved at the National Space Science Data Center (NSSDC), with the set of ISTP implementation guidelines specially designed for space physics data sets by the Space Physics Data Facility (associated with the NSSDC). The ISTP guidelines were developed to facilitate searching, plotting, merging, and subsetting of data sets. We focus here on the plotting application. A prototype software package was developed to plot key parameter (KP) data from the ISTP program at the Science Planning and Operations Facility (SPOF). The ISTP Key Parameter Visualization Tool is based on the Interactive Data Language (IDL) and is keyed to the ISTP guidelines, reading data stored in CDF. With the combination of CDF, the ISTP guidelines, and the visualization software, we can look forward to easier and more effective data sharing and use among ISTP scientists.

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

We are delighted to present the Proceedings of the 18th International School on Condensed Matter Physics: Challenges of Nanoscale Science: Theory, Materials, Applications, organized by the Institute of Solid State Physics of the Bulgarian Academy of Sciences and chaired by Professor Alexander G Petrov. On this occasion the School was held in memory of Professor Nikolay Kirov (1943-2013), former Director of the Institute and Chairman between 1991 and 1998. The 18ISCMP was one of several events dedicated to the 145th anniversary of the Bulgarian Academy of Sciences in 2014, and was held in the welcoming Black Sea resort of St. Constantine and Helena near Varna, at the Hotel and Congress Centre Frederic Joliot-Curie. Participants from 16 countries delivered 32 invited lectures, and 71 contributed posters were presented over three lively and well-attended evening sessions. Manuscripts submitted to the Proceedings were refereed in accordance with the guidelines of the Journal of Physics: Conference Series, and we believe the papers published herein testify to the high technical quality and diversity of contributions. A satellite meeting, Transition Metal Oxide Thin Films - Functional Layers in Smart Windows and Water Splitting Devices: Technology and Optoelectronic Properties was held in parallel with the School (http://www.inera.org, 3-6 Sept 2014). This activity, which took place under the FP7-funded project INERA, offered opportunities for crossdisciplinary discussions and exchange of ideas between both sets of participants. As always, a major factor in the success of the 18ISCMP was the social programme, headed by the organized events (Welcome and Farewell Parties) and enhanced in no small measure by a variety of pleasant local restaurants, bars and beaches. We are most grateful to staff of the Journal of Physics: Conference Series for their continued support for the School, this being the third occasion on which the Proceedings have been published under its

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

The present volume contains the lectures and short talks given at the XX International School on Nuclear Physics, Neutron Physics and Applications. The School was held from 16-22 September 2013 in 'Club Hotel Bolero' located in 'Golden Sands' (Zlatni Pyasaci) Resort Complex on the Black Sea coast, near Varna, Bulgaria. The School was organized by the Institute for Nuclear Research and Nuclear Energy of Bulgarian Academy of Sciences. Co-organizer of the School was the Bulgarian Nuclear Regulatory Agency and the Bogoliubov Laboratory of Theoretical Physics of Joint Institute for Nuclear Research - Dubna. Financial support was also provided by the Bulgarian Ministry of Education and Science. According to the long-standing tradition the School has been held every second year since 1973. The School's program has been restructured according to our enlarged new international links and today it is more similar to an international conference than to a classical nuclear physics school. This new image attracts many young scientists and students from around the world. This year, 2013, we had the pleasure to welcome more than sixty distinguished scientists as lecturers. Additionally, twenty young colleagues received the opportunity to present a short contribution. Ninety-four participants altogether enjoyed the scientific presentations and discussions as well as the relaxing atmosphere at the beach and during the pleasant evenings. The program of the School ranged from latest results in fundamental areas such as nuclear structure and reactions to the hot issues of application of nuclear methods, reactor physics and nuclear safety. The main topics have been the following: Nuclear excitations at various energies. Nuclei at high angular moments and temperature. Structure and reactions far from stability. Symmetries and collective phenomena. Methods for lifetime measurements. Astrophysical aspects of nuclear structure. Neutron nuclear physics. Nuclear data. Advanced methods in

The International Linear Collider Technical Design Report (TDR) describes in four volumes the physics case and the design of a 500 GeV centre-of-mass energy linear electron-positron collider based on superconducting radio-frequency technology using Niobium cavities as the accelerating structures. The accelerator can be extended to 1 TeV and also run as a Higgs factory at around 250 GeV and on the Z0 pole. A comprehensive value estimate of the accelerator is give, together with associated uncertainties. It is shown that no significant technical issues remain to be solved. Once a site is selected and the necessary site-dependent engineering is carriedmore » out, construction can begin immediately. The TDR also gives baseline documentation for two high-performance detectors that can share the ILC luminosity by being moved into and out of the beam line in a "push-pull" configuration. These detectors, ILD and SiD, are described in detail. They form the basis for a world-class experimental programme that promises to increase significantly our understanding of the fundamental processes that govern the evolution of the Universe.« less

Logo Logo The XV International Seminar on Physics and Chemistry of Solids (ISPCS15) was held from 7-10 June 2009 in Szklarska Poręba. Over eighty participants joined together in this mountain resort, at the foot of Szrenica peak, in the Polish part of the Sudety range. The majority or participants, in accordance with Seminar tradition, were from Ukraine and Poland. The pleasant and warm atmosphere created by the organizers was conducive to fruitful discussions, making new contacts and to joyful gatherings with friends. Even the rainy weather could not change that. Lectures and communications mainly covered the fields of solid state physics and chemistry, and possible applications. This time, however, a new section was introduced - one devoted to modern topics in liquid chemistry. Sometimes such a look over the borders of scientific specialties leads to interesting insights and original research solutions. Some of the papers presented during ISPCS15 are collected in this volume. Their diversity is representative of both the scope and character of this Seminar. The majority of the papers are research reports, but a review article and a paper focussed on problems connected with environmental protection are also included. This Conference has functioned for over a decade due to the permanent support of the rectors of both co-organizing universities: Professor Ivan Vakarchuk from Ivan Franko National University of Lviv and Professor Zygmunt Bąk from Jan Dlugosz University in Częstochowa. It is our pleasure, on behalf of the all participants of the past Seminars, to express our gratitude for this assistance. We would also like to thank all the invited speakers who kindly accepted our invitation, namely Professors Roman Gladyshevskii (Ivan Franko National University, Lviv, Ukraine), Mihaela Gulea (Laboratoire de Chimie Moleculare et Thioorganique, CAEN, France), Osama I Abd El-Salam (National Research
Over the past century, physicists have sought to explain the character of the matter and energy in our universe, to show how the basic forces of nature and the building blocks of matter come about, and to explore the fabric of space and time. In the past three decades, experiments at laboratories around the world have given us a precise confirmation of the underlying theory called the standard model. These particle physics advances have a direct impact for our understanding of the structure of the universe, both at its inception in the Big Bang, and in its evolution to the present and future. The final synthesis is not yet fully clear, but we know with confidence that major discoveries expanding the standard model framework will occur at the next generation of accelerators. The Large Hadron Collider (LHC) being built at CERN will take us into the discovery realm. The proposed International Linear Collider (ILC) will extend the discoveries and provide a wealth of precision measurements that are essential for giving deeper understanding of their meaning, and pointing the way to further evolution of particle physics in the future. A world-wide consensus has formed for a baseline ILC project at energies of 500 GeV and beyond. The choice of the superconducting technology as basis for the ILC has paved the way for a global design effort which has now taken full speed.

Postpartum physical activity can improve mood, maintain cardiorespiratory fitness, improve weight control, promote weight loss, and reduce depression and anxiety. This review summarizes current guidelines for postpartum physical activity worldwide. PubMed (MedLINE) was searched for country-specific government and clinical guidelines on physical activity following pregnancy through the year 2013. Only the most recent guideline was included in the review. An abstraction form facilitated extraction of key details and helped to summarize results. Six guidelines were identified from five countries (Australia, Canada, Norway, United Kingdom, United States). All guidelines were embedded within pregnancy-related physical activity recommendations. All provided physical activity advice related to breastfeeding and three remarked about physical activity following Caesarean delivery. Recommended physical activities mentioned in the guidelines included aerobic (3/6), pelvic floor exercise (3/6), strengthening (2/6), stretching (2/6), and walking (2/6). None of the guidelines discussed sedentary behavior. The guidelines that were identified lacked specificity for physical activity. Greater clarity in guidelines would be more useful to both practitioners and the women they serve. Postpartum physical activity guidelines have the potential to assist women to initiate or resume physical activity following childbirth, so that they can transition to meeting recommended levels of physical activity. Health care providers have a critical role in encouraging women to be active at this time, and the availability of more explicit guidelines may assist them to routinely include physical activity advice in their postpartum care.

As medical technology evolves and patient needs increase, the need for well-trained and highly professional medical physicists (MPs) becomes even more urgent. The roles and responsibilities of MPs in various departments within the hospital are diverse and demanding. It is obvious that training, continuing education and professional development of MPs have become essential. One of the ways for an MP to advance his or her knowledge is to participate in conferences and congresses. Last year, the 22nd International Conference of Medical Physics (ICMP 2016) took place in Bangkok, Thailand. The event attracted 584 delegates with most of the participants coming from Asia. It attracted also delegates from 42 countries. The largest delegations were from Thailand, Japan and South Korea. ICMP 2016 included 367 oral presentations and e-posters, most of these being in the fields of Radiation Therapy, Medical Imaging and Radiation Safety. All abstracts were published as an e-book of Abstracts in a supplement to the official IOMP Journal. Many companies had exhibition stands at ICMP2016, thus allowing the participants to see the latest developments in the medical physics-related industry. The conference included 42 mini-symposia, part of the first "IOMP School" activity, covering various topics of importance for the profession and this special issue follows from the success of the conference.

The International Solar Terrestrial Physics Program (ISTP) evolved from the individual plans of US, Japanese and European countries to develop space missions to expand our knowledge of the Sun-Earth connection as a "system". Previous experience with independent missions amply illustrated the critical need for coordinated and simultaneous observations in key regions of Sun-Earth space in order to resolve time-space ambiguities and cause-effect relationships. Mission studies such as the US Origins of Plasmas in the Earth's Neighborhood (OPEN), Geotail in Japan, the Solar Heliospheric Observatory in Europe and the Regatta and other magnetospheric missions in the former Soviert Union, formed the early conceptual elements that eventually led to the ISTP program. The coordinating role developed by the Inter-Agency-Consultative-Group (IACG) integrated by NASA, ESA, ISAS and IKI and demonstrated during the comet Halley apparition in 1986, was continued to include solar-terrestrial research and the mission elements described above. In addition to the space elements, a most important component of the coordination effort was the inclusion of data networks, analysis and planning tools as well as globally accessible data sets by the scientific community at large. This approach enabled the active and direct participation of scientists in developing countries in one of the most comprehensive solar-terrestrial research programs implemented to date. The creation of multiple ISTP data repositories throughout the world has enabled a large number of scientists in developing countries to have direct access to the latest spacecraft observations and a most fruitful interaction with fellow researchers throughout the world. This paper will present a review of the evolution of the ISTP program, its products, analysis tools, data bases, infrastructure and lessons learned applicable to future international collaborative programs.

One important impact in the education process is the formation of one's attitude. A person's attitude is a manifestation of the value of a person's existing character. In the education process at school, the introduction and planting of character values can be integrated with the process of the schooling itself. The history of physics subject can be used in an integrated manner in the formation of attitudes simultaneously with the subject studied, so do inphysics learning. To know the utilization of the history of physics in integrating the character values in line with the process of physics learning, has been done a research to physics teachers at the physics teacher working group (known as MGMP Fisika) in Semarang city. The teachers have various perceptions toward the history of physics, at least the history of physics could be complemented to the physics, but they have not realized the usefulness of the history of physics in relation with the character education. Only about 42% of the physics teachers studied harnessed the history of physics for the development of education character attitudes integrated with the learning of physics itself. To achieve this goal physics teachers should carefully choose the right expression when explaining the phenomena and theories of physics. Recognizing the importance of the history of physics in a comprehensive physics learning, not just only to emphasize in the cognitive aspect, it is necessary to strengthen the mastery of physics history for prospective teachers and physics teachers through various ways.
When handling , I recalled how one set of sixth-form students that I taught affectionately referred to Jim Breithaupt's large format book Understanding Physics for Advanced Level as `Big Jim'. This package, for GCSE students and teachers, is its younger brother. Key Science Physics was reviewed in this journal over four years ago. Now it is in a new edition with an expanded ring file of teacher resources (a Teacher's Guide and Extension File). It has been expanded for a wider range of students to meet the requirements of all GCSE syllabuses with additional topics for IGCSE and IB. The international bit seems to be among materials in the file of resources and does not appear in the title of the students' textbook. This is not one of those purchases that will only get occasional use and be left in a department library but it is one that contains sufficient excellent material to become central to any GCSE Physics course. For the students there is a single-volume 396-page textbook in full colour (not a heavyweight book). Marginal comments point out places where an Activity or Assignment from the Extension File fits in. All the materials in the teacher's Extension File are cross referenced to the numbering of this textbook, i.e. its Themes, Topics, Checkpoints, Tests etc, not to page numbers. The margin is used in other attractive ways to highlight a summary, propose a first thought or provide a topic summary. The text is fruitful mix of pure physics, applications and personalities. To support the students' practical work the Extension File contains photocopiable sheets. For the activities and assignments a few contain a harder version to give access to the higher levels of attainment. Four alternatives to practical questions are given; there are also exam questions and multiple choice questions for each topic. These all have helpful mark schemes on the teacher's answers pages. What else do you get? A Glossary collection of sheets to photocopy with space to enter a

It has been established by physics education researchers that there is a correlation between the learner’s behavior, their epistemological beliefs with which they come to the classrooms, and their success in a course. This study of Indian students and teachers explores expectations and beliefs in learning physics at the secondary and tertiary levels by making use of the Maryland Physics Expectation (MPEX) survey, which has been tested for both its validity and its reliability. The MPEX was administered to a sample of 265 Indian students at three different levels of study: (i) XII standard (high school), (ii) undergraduate (Bachelor of Science), and (iii) master’s degree (Master of Science in Physics, MS). In India, a pre-post instruction difference between the attitudes of class XII, undergraduate, and master’s students is observed with favorable improvement in master’s students as compared to deterioration in both class XII and undergraduate students. A comparison of these results with those reported in similar studies conducted in four other countries (U.S., Turkey, Philippines, and Thailand) indicates that there is a difference between the U.S. students and those of the other three countries and also between U.S. experts and Indian teachers. In all countries (U.S., India, Turkey, Thailand, and Philippines) the basic trend of expectation from pre to post test remained the same—there was a deterioration observed in all levels of students. Indian MS students were an exception. A significant difference was observed in the expectations of U.S. experts and Indian teachers. The score of favorable views of Indian class XII and undergraduate students was observed to be less than U.S. students in many clusters. No significant difference was found between Indian male and female students’ expectations at any level of study. This study shows that most Indian students have nowhere near an expert’s expectations even after instruction, which might affect their

A growing body of research in the United States and Western Europe documents significant effects of the physical environment (toxins, pollutants, noise, crowding, chaos, housing, school and neighborhood quality) on children and adolescents’ cognitive and socioemotional development. Much less is known about these relations in other contexts, particularly the global South. We thus briefly review the evidence for relations between child development and the physical environment in Western contexts, and discuss some of the known mechanisms behind these relations. We then provide a more extensive review of the research to date outside of Western contexts, with a specific emphasis on research in the global South. Where the research is limited, we highlight relevant data documenting the physical environment conditions experienced by children, and make recommendations for future work. In these recommendations, we highlight the limitations of employing research methodologies developed in Western contexts (Ferguson & Lee, 2013). Finally, we propose a holistic, multidisciplinary and multilevel approach based on Bronfenbrenner’s (1979) bioecological model to better understand and reduce the aversive effects of multiple environmental risk factors on the cognitive and socioemotional development of children across the globe.

Background Many practicing physicians lack skills in physical examination. It is not known whether physical examination skills already show deficiencies after an early phase of clinical training. At the end of the internal medicine clerkship students are expected to be able to perform a general physical examination in every new patient encounter. In a previous study, the basic physical examination items that should standardly be performed were set by consensus. The aim of the current observational study was to assess whether medical students were able to correctly perform a general physical examination regarding completeness as well as technique at the end of the clerkship internal medicine. Methods One hundred students who had just finished their clerkship internal medicine were asked to perform a general physical examination on a standardized patient as they had learned during the clerkship. They were recorded on camera. Frequency of performance of each component of the physical examination was counted. Adequacy of performance was determined as either correct or incorrect or not assessable using a checklist of short descriptions of each physical examination component. A reliability analysis was performed by calculation of the intra class correlation coefficient for total scores of five physical examinations rated by three trained physicians and for their agreement on performance of all items. Results Approximately 40% of the agreed standard physical examination items were not performed by the students. Students put the most emphasis on examination of general parameters, heart, lungs and abdomen. Many components of the physical examination were not performed as was taught during precourses. Intra-class correlation was high for total scores of the physical examinations 0.91 (p <0.001) and for agreement on performance of the five physical examinations (0.79-0.92 p <0.001). Conclusions In conclusion, performance of the general physical examination was already below

Physicians spend less time at the bedside in the modern hospital setting which has contributed to a decline in physical diagnosis, and in particular, cardiopulmonary examination skills. This trend may be a source of diagnostic error and threatens to erode the patient-physician relationship. We created a new bedside cardiopulmonary physical diagnosis curriculum and assessed its effects on post-graduate year-1 (PGY-1; interns) attitudes, confidence and skill. One hundred five internal medicine interns in a large U.S. internal medicine residency program participated in the Advancing Bedside Cardiopulmonary Examination Skills (ACE) curriculum while rotating on a general medicine inpatient service between 2015 and 2017. Teaching sessions included exam demonstrations using healthy volunteers and real patients, imaging didactics, computer learning/high-fidelity simulation, and bedside teaching with experienced clinicians. Primary outcomes were attitudes, confidence and skill in the cardiopulmonary physical exam as determined by a self-assessment survey, and a validated online cardiovascular examination (CE). Interns who participated in ACE (ACE interns) by mid-year more strongly agreed they had received adequate training in the cardiopulmonary exam compared with non-ACE interns. ACE interns were more confident than non-ACE interns in performing a cardiac exam, assessing the jugular venous pressure, distinguishing 'a' from 'v' waves, and classifying systolic murmurs as crescendo-decrescendo or holosystolic. Only ACE interns had a significant improvement in score on the mid-year CE. A comprehensive bedside cardiopulmonary physical diagnosis curriculum improved trainee attitudes, confidence and skill in the cardiopulmonary examination. These results provide an opportunity to re-examine the way physical examination is taught and assessed in residency training programs.

The IWTCP-1 was also an External Activity of the Asia Pacific Center for Theoretical Physics (APCTP). The overriding goal of the IWTCP is to provide an international forum for scientists and engineers from academia to share ideas, problems and solution relating to the recent advances in theoretical physics as well as in computational physics. The main IWTCP motivation is to foster scientific exchanges between the Vietnamese theoretical and computational physics community and world-wide scientists as well as to promote high-standard level of research and education activities for young physicists in the country. About 110 participants coming from 10 countries participated in the conference and the workshop. 4 invited talks, 18 oral contributions and 46 posters were presented at the conference. In the workshop we had one keynote lecture and 9 invited talks presented by international experts in the fields of theoretical and computational physics, together with 14 oral and 33 poster contributions. The proceedings were edited by Nguyen Tri Lan, Trinh Xuan Hoang, and Nguyen Ai Viet. We would like to thank all invited speakers, participants and sponsors for making the conference and the workshop successful. Nguyen Ai Viet Chair of NCTP-38 and IWTCP-1

To explore issues associated with measuring physical activity using the International Physical Activity Questionnaire (IPAQ)-long form in adults living in a mid-sized Brazilian city. A stratified random sampling procedure was used to select a representative sample of adults living in Rio Claro. This yielded 1572 participants who were interviewed using the IPAQ-long form. The data were analysed using standard statistical procedures. Overall, 83% of men and 89% of women reported at least 150 min of combined moderate and/or vigorous physical activity per week. Reliable values of leisure and transportation-related physical activity were observed for both males and females. With regard to the household and work-related physical activity domains, both males and females reported unusually high levels of participation. The IPAQ-long form appears to overestimate levels of physical activity for both males and females, suggesting that the instrument has problems in measuring levels of physical activity in Brazilian adults. Accordingly, caution is warranted before using IPAQ data to support public policy decisions related to physical activity. Copyright © 2012 The Royal Society for Public Health.

In 1999 the General Assembly of the International Union of Pure and Applied Physics (IUPAP) voted to establish a Working Group on Women in Physics with the following charge: to survey the situation for women in physics in IUPAP member countries; to analyze and report the data collected along with suggestions on how to improve the situation; to suggest ways that women can become more involved in IUPAP, including the Liaison Committees, the Commissions, the Council, and the General Assemblies; and to report all findings at the next General Assembly in 2002. The Working Group was established in 2000 with 11 members representing North and South America, Europe, Asia and the Middle East/Africa. The Group has been gathering data on women in physics and is planning to hold an International Conference on Women in Physics at UNESCO Headquarters in Paris in March, 2002. I will discuss some of the findings and the plans for the future.

Medical physics is a health profession where principles of applied physics are mostly directed towards the application of ionizing radiation in medicine. The key role of the medical physics expert in safe and effective use of ionizing radiation in medicine was widely recognized in recent European reference documents like the European Union Council Directive 2013/59/EURATOM (2014), and European Commission Radiation Protection No. 174, European Guidelines on Medical Physics Expert (2014). Also the International Atomic Energy Agency (IAEA) has been outspoken in supporting and fostering the status of medical physics in radiation medicine through multiple initiatives as technical and cooperation projects and important documents like IAEA Human Health Series No. 25, Roles and Responsibilities, and Education and Training Requirements for Clinically Qualified Medical Physicists (2013) and the International Basic Safety Standards, General Safety Requirements Part 3 (2014). The significance of these documents and the recognition of the present insufficient fulfilment of the requirements and recommendations in many European countries have led the IAEA to organize in 2015 the Regional Meeting on Medical Physics in Europe, where major issues in medical physics in Europe were discussed. Most important outcomes of the meeting were the recommendations addressed to European member states and the survey on medical physics status in Europe conducted by the IAEA and European Federation of Organizations for Medical Physics. Published recommendations of IAEA Regional Meeting on Medical Physics in Europe shall be followed and enforced in all European states. Appropriate qualification framework including education, clinical specialization, certification and registration of medical physicists shall be established and international recommendation regarding staffing levels in the field of medical physics shall be fulfilled in particular.

The 3^rd International Conference on Women in Physics (ICWIP), held in Seoul, Korea, in October 2008, brought together 300 participants from 57 countries, including a diverse 22-member U.S. Delegation, for a 3-day summit of stimulating discussions, thought-provoking presentations, inspirational posters, and networking. Held under the auspices of the Working Group on Women in Physics of the International Union of Pure and Applied Physics (IUPAP), this meeting built on the successes of the 1^st (Paris, 2002) and 2^nd (Rio de Janeiro, 2005) Conferences and further clarified the importance of diversifying the field of physics worldwide. Although considerable progress has been made since 2002, it was clear that the global scientific workforce is still under-utilizing a large percentage of the available female talent pool. If human society is to benefit to its fullest from various contributions that the field of physics can offer in addressing global issues of economic crisis, energy, environment, water, health, poverty, and hunger, women of all races and nationalities need to become fully included and engaged in the national and international physical community. To address these and many other issues, the ICWIP unanimously approved a five-part resolution to IUPAP recommending actions to promote the recruitment, retention, and advancement of women in physics and related fields.
More than 35 percent of the physics graduate students in the US are temporary visa holders. Many of these students work in large international collaborations and must travel abroad for research and international conferences, sometimes more than once a year. In many cases, students have to reapply for their visas in order to return to the U.S., a process that can be time-consuming and costly. Furthermore, many international students cannot leave the U.S. even in the case of an emergency because a slow visa process may mean deferring for a semester or losing financial support. Thus visa issues affect not only the scholastic life of students but also their personal lives. Finding ways to resolve these issues could positively affect the quality of graduate research by eliminating these extra hurdles to the progress of international physics graduate students.

This study was carried out to determine knowledge, attitudes, and practices of intern nurses who completed the nursing internship program on the use of physical restraints. This research was conducted using descriptive and cross-sectional research design. The study sample comprises 91 fourth-grade students who took an integrated curriculum and completed the nursing internship program. The data were collected with the Demographic Characteristics Questionnaire and the Levels of Knowledge, Attitudes and Practices of Staff Regarding Physical Restraints Questionnaire. For the assessment of the data, percentages, the arithmetic mean, and t test were used. The findings indicated that, of the intern nurses, 95.6% observed the use of physical restraints during their education, and 69.2% applied physical restraints. The mean knowledge, attitude, and practice scores of the nurses for physical restraint were 9.38 ± 1.19 (0-11 points), 34.70 ± 5.62 (12-48 points), and 37.95 ± 2.32 (14-42 points), respectively. Intern nurses' knowledge about how to use physical restraints was at a very good level; they displayed positive attitudes, and they used their knowledge and attitudes in their practices to a great extent. Although there are studies on the knowledge, attitudes, and practices of nurses working in the fields of elderly care, rehabilitation, and psychiatry in acute care units, there are no studies investigating intern nurses and other nursing students. However, intern nurses about to begin their careers should make accurate decisions regarding the use of physical restrains if they are to ensure patient safety and to fulfill this application effectively in their professional lives.

J Strength Cond Res 31(9): 2379-2387, 2017-The purpose of this study was to provide a detailed analysis of the physical demands of competitive international female soccer match play. A total of 148 individual match observations were undertaken on 107 outfield players competing in competitive international matches during the 2011-2012 and 2012-2013 seasons, using a computerized tracking system (Prozone Sports Ltd., Leeds, England). Total distance and total high-speed running distances were influenced by playing position, with central midfielders completing the highest (10,985 ± 706 m and 2,882 ± 500 m) and central defenders the lowest (9,489 ± 562 m and 1,901 ± 268 m) distances, respectively. Greater total very high-speed running distances were completed when a team was without (399 ± 143 m) compared to with (313 ± 210 m) possession of the ball. Most sprints were over short distances with 76% and 95% being less than 5 and 10 m, respectively. Between half reductions in physical performance were present for all variables, independent of playing position. This study provides novel findings regarding the physical demands of different playing positions in competitive international female match play and provides important insights for physical coaches preparing elite female players for competition.

Performance of a focused physical examination will induce a high cognitive load for medical students in the early phase of the clinical clerkships. To come to a workable and clinically applicable standard physical examination for medical students to be used in every new patient in the daily clinical practice of internal medicine. A questionnaire held among physicians that supervise students during the clerkship of internal medicine in one Dutch training region. Of the complete list of physical examination 55 items were considered to be an integral part of the standard general physical examination for medical students. Most emphasized were elements of the physical examination aimed at general parameters, thorax and abdomen, vascular status, lymph nodes, spinal column, skin and some parts of the neurological examination. The standard physical examinations performed by supervisors themselves contain fewer items than they expected from the students. The expectations a supervisor has towards the student correlates with the frequency with which they apply the various components in their own physical examination. This study provides us with a 'core' physical examination for medical students that can be applied in the early phase of the clinical clerkships.
The 38th International Conference on High Energy Physics (ICHEP) held in Chicago from August 3 to 10, 2016 was for physicists from around the world to gather to share the latest advancements in particle physics, astrophysics/cosmology, and accelerator science and to discuss plans for major future facilities. DOE funding provided partial support for space rental audio-visual services for scientific presentations at the conference.

The International Physical Activity Questionnaire (IPAQ) has been widely used to assess physical activity in healthy populations. The present study compared physical activity assessed by the long, self-administrated version of the International Physical Activity Questionnaire with physical activity assessed by accelerometry in patients with fibromyalgia. A total of 99 (five men) participants with fibromyalgia completed the International Physical Activity Questionnaire and wore an accelerometer for nine consecutive days. We analysed the correlations of physical activity expressed as min · day(-1) of light, moderate, vigorous, and moderate to vigorous (MVPA) intensity, as well as time spent sitting, by the International Physical Activity Questionnaire and accelerometry by Spearman correlations. Bland and Altman plots were performed to verify the agreements between both instruments. The results showed weak yet significant correlations (Rs = 0.15-0.39, all P < 0.05) in all physical activity intensities between the two instruments, except for sedentary time. The highest correlations were observed for physical activity at home or in garden (Rs = 0.297, P < 0.01). The results suggest that the long self-administrated International Physical Activity Questionnaire is a questionable instrument to assess physical activity in patients with fibromyalgia. Therefore, physical activity measurement in fibromyalgia patients should not be limited solely to self-reported measures.

Family violence has been associated with various negative outcomes among children and adolescents. Yet, less is known about how unique forms of physical family violence contribute to externalizing and internalizing behaviors based on a child's developmental stage. Using data from the Illinois Families Study and administrative Child Protective Services data, we explored the relation between 3 types of physical family violence victimization and externalizing and internalizing behaviors among a sample of 2,402 children and adolescents. After including parent and family level covariates in Poisson regressions, we found that a unique form of family violence victimization was associated with increased externalizing behaviors among children at each age group: exposure to physical intimate partner violence (IPV) among children ages 3-5, exposure to the physical abuse of a sibling among children ages 6-12, and child physical abuse among adolescents ages 13-18. No form of physical family violence was significantly associated with internalizing behaviors for children in any age group. Including exposure to the child maltreatment of a sibling is crucial when attempting to contextualize children's responses to family violence and providing comprehensive services in an effort to enhance the well-being of all children in a family.

Internationalization is expanding its presence in higher education in the United States. Reflecting this trend that includes incorporating global perspectives in the curricula, physical therapist education programmes increasingly offer international opportunities such as International Service-Learning (ISL) to their students. Service-learning, a teaching strategy that integrates community service with structured learning activities, has gained broad acceptance in health professions education including physical therapy, and is therefore the focus of this paper. The specific purposes of this paper were to identify and analyse the commonalities that existed among established ISL programmes within physical therapist education programmes in terms of structures and processes, and to consider its broader implications for physical therapist education. A descriptive, exploratory study was performed using grounded theory. Snowball and purposive, theoretical sampling yielded 14 faculty members with experience in international service, international learning or ISL in physical therapist education programmes. Faculty were interviewed by phone. Interview transcriptions and course documents were analysed applying grounded theory methodology. Data from eight programmes which met the operational definition of established ISL were used to address the purposes of this paper. Five phases of establishing an ISL programme were identified: development, design, implementation, evaluation, and enhancement. Although no single model exists for ISL in physical therapist education; commonalities in structures and processes were identified in each phase. However, attention to service objectives and outcomes is lacking. While analysis revealed that each programme shared commonalities and demonstrated differences in structures and processes compared with the other programmes, the study demonstrated a general lack of focus on formal community outcomes which raises ethical

These proceedings arose from the 8th Asian International Seminar on Atomic and Molecular Physics (AISAMP) which was held at the University of Western Australia 24-28 November 2008. The history of AISAMP (Takayanagi and Matsuzawa 2002) recognizes its origin from the Japan-China meeting of 1985, and the first use of the name 'The First Asian International Seminar on Atomic and Molecular Physics (AISAMP)' in 1992. The initial attendees, Japan and China, were joined subsequently by scientists from Korea, Taiwan, India, Australia and recently by Malaysia, Thailand, Vietnam, Turkey Iran, UK and USA. The main purpose of the biennial AISAMP series is to create a wide forum for exchanging ideas and information among atomic and molecular scientists and to promote international collaboration. The scope of the AISAMP8 meeting included pure, strategic and applied research involving atomic and molecular structure and processes in all forms of matter and antimatter. For 2008 the AISAMP conference incorporated the Australian Atomic and Molecular Physics and Quantum Chemistry meeting. The topics for AISAMP8 embraced themes from earlier AISAMP meetings and reflected new interests, in atomic and molecular structures, spectroscopy and collisions; atomic and molecular physics with laser or synchrotron radiation; quantum information processing using atoms and molecules; atoms and molecules in surface physics, nanotechnology, biophysics, atmospheric physics and other interdisciplinary studies. The implementation of the AISAMP themes, as well as the international representation of research interests, is indicated both in the contents list of these published manuscripts as well as in the program for the meeting. Altogether, 184 presentations were made at the 8th AISAMP, including Invited Talks and Contributed Poster Presentations, of which 60 appear in the present Proceedings after review by expert referees in accordance with the usual practice of Journal of Physics: Conference Series of

A structured online survey was used to establish the views of 2,684 practising clinicians of all ages in multiple countries about the value of the physical examination in the contemporary practice of internal medicine. 70% felt that physical examination was 'almost always valuable' in acute general medical referrals. 66% of trainees felt that they were never observed by a consultant when undertaking physical examination and 31% that consultants never demonstrated their use of the physical examination to them. Auscultation for pulmonary wheezes and crackles were the two signs most likely to be rated as frequently used and useful, with the character of the jugular venous waveform most likely to be rated as -infrequently used and not useful. Physicians in contemporary hospital general medical practice continue to value the contribution of the physical examination to assessment of outpatients and inpatients, but, in the opinion of trainees, teaching and demonstration could be improved. © Royal College of Physicians 2017.

Finding the "right-size" physical therapy workforce is an increasingly important issue, but it has had limited study, particularly across nations. This perspective article provides a comprehensive examination of physical therapy workforce issues across 4 countries (United States, Singapore, Portugal, and Bangladesh), which were deliberately selected to allow consideration of key contextual factors. This investigation provides a theoretical model uniquely adapted to focus on variables most likely to affect physical therapy workforce needs. This theoretical model was used to guide acquisition of public domain data across the respective countries. The data then were used to provide a contextualized interpretation about the physical therapy workforce supply (ie, physical therapists per capita) across the 4 countries in light of the following factors: indicators of physical therapy need, financial and administrative barriers affecting physical therapy access and demand, the proportion of physical therapy graduates (with varying trends over time across the countries), and the role of emigration/immigration in supply inequalities among countries of lower and higher income. In addition, both the physical therapy workforce supply and scope of practice were analyzed in the context of other related professions across the 4 countries. This international comparison indicated that there may not be a "one-size-fits-all" recommendation for physical therapy workforce supply across countries or an ideal formula for its determination. The optimal, country-specific physical therapy workforce supply appears to be affected by discipline-specific health care and contextual factors that may vary across countries, and even within the same country. This article provides a conceptual framework and basis for such contextualized evaluations of the physical therapy workforce. © 2016 American Physical Therapy Association.

The Working Group on Women in Physics of the International Union of Pure and Applied Physics (IUPAP) subcontracted with the Statistical Research Center of the American Institute of Physics (AIP) to conduct an international study on women in physics. This study had two parts. First, we conducted a benchmarking study to identify reliable sources and collect data on the representation of women in physics in as many IUPAP member countries as possible. Second, we conducted an international survey of individual women physicists. The survey addressed issues related to both education and employment. On the education side, we asked about experiences and critical incidents from secondary school through the highest degree earned. On the employment side, we asked about how the respondents' careers had evolved and their self-assessment of how well their careers had progressed. In addition, the questionnaire also addressed issues that cut across education and employment, such as the impact of marriage and children, the factors that contributed the most toward the success they had achieved to date, and suggestions for what could be done to improve the situation of women physicists.

The objectives of this study were to identify perceived priorities related to military personnel's health and physical performance, among attendees at the 4th International Congress on Soldiers' Physical Performance (ICSPP), and to determine if perceived priorities had changed between the 3rd ICSPP survey held in 2014 and the 4th ICSPP survey held in 2017. Electronic survey. Respondents were asked to grade priority areas on a Likert scale, and average ratings were used to rank priority areas. Responses to free text questions were analyzed qualitatively. Responses to the 4th ICSPP survey were described and compared to responses to the 3rd ICSPP survey. The 4th ICSPP survey respondents were a diverse group (40.6% military, 58.9% civilian). The two most important priority areas identified were physical demands in operational environments (mean score=4.41/5) and measuring physical performance/fitness (4.38/5), which were also the top two areas in the 3rd ICSPP survey. There was remarkable overlap in the rankings of priority areas between the two surveys. Sleep and nutrition were emerging priority areas and were perceived as relatively more important in the 4th ICSPP survey compared to the 3rd ICSPP survey. The greatest perceived emerging threat was resilience/psychological fitness of recruits (4.16/5). Physiological status monitoring (2.79/4) was identified as the most important technology. Despite the diverse backgrounds of the respondents, there was a clear continuing consensus about perceived important priority areas influencing military personnel's health and physical performance. Soldier resiliency and assessment of physiological status were research topics identified as top priorities. Copyright © 2018 Sports Medicine Australia. All rights reserved.

Sedentarism is considered a risk factor for coronary heart disease and death from any cardiovascular disease. The International Physical Activity Questionnaire (IPAQ) assesses physical activity in metabolic equivalents, using 4 dimensions: occupation, transportation, household activities, and leisure-time physical activity. The purpose of this investigation was to assess physical activity levels in the patients enrolled in the Maracaibo City Metabolic Syndrome Prevalence Study, currently undertaken by the "Dr. Félix Gómez" Endocrine-Metabolic Research Center. Two thousand one hundred eight individuals were recruited and subjected to a standard Medical chart, Graffar scale, and IPAQ long form, applied by trained personnel. Description of the population was done using mean, SD, and coefficient of variation. IPAQ scores were analyzed as medians and distributed by percentiles. From the 2108 individuals, 46.9% were men and 53.1% were women. The most prevalent physical activity was high physical activity with 39.9%, followed by moderate physical activity with 36.9% and low physical activity with 23.2%. Medians for each IPAQ dominion were occupation with 0.00 (0.00-66.00), transportation with 165.00 (0.00-463.00), household activities with 772.50 (0.00-2520.00), and leisure time with 0.00 (0.00-594.00). Using leisure-time scores, a new reclassification was conducted, obtaining 1245 subjects with 0 metabolic equivalents in this dominion. From this new subsample, 43.6% had High physical activity, 56.95% had Moderate physical activity, and 91% had Low physical activity, demonstrating an important overestimation in the former sample results. IPAQ overestimates moderate and vigorous activity in the adult population of the Maracaibo Municipality. Overestimation is mainly located in the household- and gardening-related activity.

Physical inactivity is a global problem which is related to many chronic health disorders. Physical activity scales which allow cross-cultural comparisons have been developed. The goal was to assess the reliability and validity of a Turkish version of the International Physical Activity Questionnaire (IPAQ). 1,097 university students (721 women, 376 men; ages 18-32) volunteered. Short and long forms of the IPAQ gave good agreement and comparable 1-wk. test-retest reliabilities. Caltrac accelerometer data were compared with IPAQ scores in 80 participants with good agreement for short and long forms. Turkish versions of the IPAQ short and long forms are reliable and valid in assessment of physical activity.

Advancements in geographic information systems over the past two decades have increased the specificity by which an individual's neighborhood environment may be spatially defined for physical activity and health research. This study investigated how different types of street network buffering methods compared in measuring a set of commonly used built environment measures (BEMs) and tested their performance on associations with physical activity outcomes. An internationally-developed set of objective BEMs using three different spatial buffering techniques were used to evaluate the relative differences in resulting explanatory power on self-reported physical activity outcomes. BEMs were developed in five countries using 'sausage,' 'detailed-trimmed,' and 'detailed,' network buffers at a distance of 1 km around participant household addresses (n = 5883). BEM values were significantly different (p < 0.05) for 96% of sausage versus detailed-trimmed buffer comparisons and 89% of sausage versus detailed network buffer comparisons. Results showed that BEM coefficients in physical activity models did not differ significantly across buffering methods, and in most cases BEM associations with physical activity outcomes had the same level of statistical significance across buffer types. However, BEM coefficients differed in significance for 9% of the sausage versus detailed models, which may warrant further investigation. Results of this study inform the selection of spatial buffering methods to estimate physical activity outcomes using an internationally consistent set of BEMs. Using three different network-based buffering methods, the findings indicate significant variation among BEM values, however associations with physical activity outcomes were similar across each buffering technique. The study advances knowledge by presenting consistently assessed relationships between three different network buffer types and utilitarian travel, sedentary behavior, and leisure

Since the International Conference on Nuclear Criticality Safety (ICNC) 2007, the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) have continued to expand their efforts and broaden their scope. Eighteen countries participated on the ICSBEP in 2007. Now, there are 20, with recent contributions from Sweden and Argentina. The IRPhEP has also expanded from eight contributing countries in 2007 to 16 in 2011. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Criticality Safety Benchmark Experiments1' have increased from 442 evaluations (38000 pages), containing benchmark specifications for 3955 critical ormore » subcritical configurations to 516 evaluations (nearly 55000 pages), containing benchmark specifications for 4405 critical or subcritical configurations in the 2010 Edition of the ICSBEP Handbook. The contents of the Handbook have also increased from 21 to 24 criticality-alarm-placement/shielding configurations with multiple dose points for each, and from 20 to 200 configurations categorized as fundamental physics measurements relevant to criticality safety applications. Approximately 25 new evaluations and 150 additional configurations are expected to be added to the 2011 edition of the Handbook. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments2' have increased from 16 different experimental series that were performed at 12 different reactor facilities to 53 experimental series that were performed at 30 different reactor facilities in the 2011 edition of the Handbook. Considerable effort has also been made to improve the functionality of the searchable database, DICE (Database for the International Criticality Benchmark Evaluation Project) and verify the accuracy of the data contained therein. DICE will be discussed in separate papers at ICNC 2011. The status of the ICSBEP and

Background and Aims Excessive usage of smartphones may induce social problems, such as depression and impairment of social and emotional functioning. Moreover, its usage can impede physical activity, but the relationship between smartphone addiction and physical activity is obscure. Therefore, we examined the relationship and the impact of excessive smartphone use on physical activity. Methods This study collected data through the structured questionnaire consisting of general characteristics, the number and hours of smartphone usage, and the Smartphone Addiction Proneness Scale (SAPS) from 110 Chinese international students in Korea. The body composition and physical activity, such as the total daily number of steps and consumed calories, were measured. Results In this study, high-risk smartphone users showed less physical activity, such as the total number of steps taken and the average consumed calories per day. Moreover, their body composition, such as muscle mass and fat mass, was significantly different. Among these factors, the hours of smartphone use revealed the proportional relationship with smartphone addiction (β = 0.209, p = 0.026), while the average number of walking steps per day showed a significant reverse proportional tendency in participants with smartphone addiction (β = –0.883, p < 0.001). Conclusions Participants with smartphone addiction were less likely to walk for each day. Namely, smartphone addiction may negatively influence physical health by reducing the amount of physical activity, such as walking, resulting in an increase of fat mass and a decrease of muscle mass associated with adverse health consequences.

Using a multisite community sample of 585 children, this study examined how protective and vulnerability factors alter trajectories of teacher-reported externalizing and internalizing behavior from kindergarten through Grade 8 for children who were and were not physically abused during the first 5 years of life. Early lifetime history of physical abuse (11.8% of sample) was determined through interviews with mothers during the prekindergarten period; mothers and children provided data on vulnerability and protective factors. Regardless of whether the child was abused, being African American; being male; having low early social competence, low early socioeconomic status (SES), and low adolescent SES; and experiencing adolescent harsh discipline, low monitoring, and low parental knowledge were related to higher levels of externalizing problems over time. Having low early social competence, low early SES, low adolescent SES, and low proactive parenting were related to higher levels of internalizing problems over time. Furthermore, resilience effects, defined as significant interaction effects, were found for unilateral parental decision making (lower levels are protective of externalizing outcomes for abused children), early stress (lower levels are protective of internalizing outcomes for abused children), adolescent stress (lower levels are protective of internalizing outcomes for abused children), and hostile attributions (higher levels are protective of internalizing outcomes for abused children). The findings provide a great deal of support for an additive or main effect perspective on vulnerability and protective factors and some support for an interactive perspective. It appears that some protective and vulnerability factors do not have stronger effects for physically abused children, but instead are equally beneficial or harmful to children regardless of their abuse status.

Physical activity and sedentary behaviour in youth have been reported to vary by sex, age, weight status and country. However, supporting data are often self-reported and/or do not encompass a wide range of ages or geographical locations. This study aimed to describe objectively-measured physical activity and sedentary time patterns in youth. The International Children's Accelerometry Database (ICAD) consists of ActiGraph accelerometer data from 20 studies in ten countries, processed using common data reduction procedures. Analyses were conducted on 27,637 participants (2.8-18.4 years) who provided at least three days of valid accelerometer data. Linear regression was used to examine associations between age, sex, weight status, country and physical activity outcomes. Boys were less sedentary and more active than girls at all ages. After 5 years of age there was an average cross-sectional decrease of 4.2% in total physical activity with each additional year of age, due mainly to lower levels of light-intensity physical activity and greater time spent sedentary. Physical activity did not differ by weight status in the youngest children, but from age seven onwards, overweight/obese participants were less active than their normal weight counterparts. Physical activity varied between samples from different countries, with a 15-20% difference between the highest and lowest countries at age 9-10 and a 26-28% difference at age 12-13. Physical activity differed between samples from different countries, but the associations between demographic characteristics and physical activity were consistently observed. Further research is needed to explore environmental and sociocultural explanations for these differences.

International Organization for Medical Physics (IOMP) which represents medical physicists in more than 80 countries decided to celebrate 7th November, birth date of the Polish and naturalized-French physicist Marie Sklodowska-Curie, as International Day of Medical Physics (IDMP). The main purpose of the initiative is to raise the visibility and awareness of medical physicist in the global community, to introduce ourselves to the general public, and bring a message to the community that a group of health professionals, the medical physicists are there to help the patients and other health professionals. First celebration was done in 2013 and now IDMP willmore » be celebrated every year. The theme of IDMP will be different each year. The theme for 2013 was ‘Radiation exposure from medical procedures, ask the Medical Physicist’. The inaugural event was celebrated in 23 countries and the amount of attention gained was remarkable. Main IDMP events were held in Poland, birthplace of Marie Curie, and France, workplace of Marie Curie. This year IOMP celebrates the 2nd IDMP and theme will be ‘Looking into the body-Advancement in Imaging through Medical Physics’ to draw attention to the profound contributions Medical Physics has made to the use of ionizing and non-ionizing radiation for the imaging of human body. A number of countries have informed about events that they are going to organize on IDMP. This gives wide attention to medical physics globally. AAPM is a major and important member of IOMP. It is hoped that AAPM will join in organizing activities. Learning Objectives: To learn about International Day of Medical Physics To become familiar with how first IDMP was celebrated in 2013 and learning achieved To understand on future plans for IDMPs.« less

We report on the physical and chemical properties of atomic steps on the surface of highly oriented pyrolytic graphite (HOPG) investigated using atomic force microscopy. Two types of step edges are identified: internal (formed during crystal growth) and external (formed by mechanical cleavage of bulk HOPG). The external steps exhibit higher friction than the internal steps due to the broken bonds of the exposed edge C atoms, while carbon atoms in the internal steps are not exposed. The reactivity of the atomic steps is manifested in a variety of ways, including the preferential attachment of Pt nanoparticles deposited on HOPG when using atomic layer deposition and KOH clusters formed during drop casting from aqueous solutions. These phenomena imply that only external atomic steps can be used for selective electrodeposition for nanoscale electronic devices.

Associations between the built environment and physical activity (PA) may vary by sociodemographic factors. However, such evidence from international studies is limited. This study tested the moderating effects of sociodemographic factors on associations between perceived environment and self-reported total PA among adults from the International Prevalence Study. Between 2002 and 2003, adults from 9 countries (N = 10,258) completed surveys assessing total PA (International Physical Activity Questionnaire-short), perceived environment, and sociodemographics (age, gender, and education). Total PA was dichotomized as meeting/not meeting (a) high PA levels and (b) minimum PA guidelines. Logistic models tested environment by sociodemographic interactions (24 total). Education and gender moderated the association between safety from crime and meeting high PA levels (interaction P < .05), with inverse associations found only among the high education group and men. Education and gender also moderated associations of safety from crime and the presence of transit stops with meeting minimum PA guidelines (interaction P < .05), with positive associations found for safety from crime only among women and presence of transit stops only among men and the high education group. The limited number of moderating effects found provides support for population-wide environment-PA associations. International efforts to improve built environments are needed to promote health-enhancing PA and maintain environmental sustainability.

These proceedings arose from the 7th Asian International Seminar on Atomic and Molecular Physics (AISAMP) which was held at the Indian Institute of Technology, Madras from 4-7 December 2006. The history of the AISAMP has been reviewed by Takayanagi http://www.physics.iitm.ac.in/~aisamp7/history.html. This international seminar/conference series grew out of the Japan-China meetings which were launched in 1985, the fourth of which was held in 1992 and carried a second title: The First Asian International Seminar on Atomic and Molecular Physics (AISAMP), thus providing a formal medium for scientists in this part of the world to report periodically and exchange their scientific thoughts. The founding nations of Japan and China were joined subsequently by Korea, Taiwan, India and Australia. The aims of the symposia included bringing together leading experts and students of atomic and molecular physics, the discussion of important problems, learning and sharing modern techniques and expanding the horizons of modern atomic and molecular physics. The fields of interest ranged from atomic and molecular structure and dynamics to photon, electron and positron scattering, to quantum information processing, the effects of symmetry and many body interactions, laser cooling, cold traps, electric and magnetic fields and to atomic and molecular physics with synchrotron radiation. Particular interest was evident in new techniques and the changes of the physical properties from atomic to condensed matter. Details of the 7th AISAMP, including the topics for the special sessions and the full programme, are available online at the conference website http://www.physics.iitm.ac.in/~aisamp7/. In total, 95 presentations were made at the 7th AISAMP, these included the Invited Talks and Contributed Poster Presentations, of which 52 appear in the present Proceedings after review by expert referees, refereed to the usual standard of the Institute of Physics journal: Journal of Physics B: Atomic

We are pleased to introduce the Proceedings of the 17th International School on Condensed Matter Physics: Open Problems in Condensed Matter Physics, Biomedical Physics and their Applications, organized by the Institute of Solid State Physics of the Bulgarian Academy of Sciences. The Chairman of the School was Professor Alexander G Petrov. Like prior events, the School took place in the beautiful Black Sea resort of Saints Constantine and Helena near Varna, going back to the refurbished facilities of the Panorama hotel. Participants from 17 different countries delivered 31 invited lecturers and 78 posters, contributing through three sessions of poster presentations. Papers submitted to the Proceedings were refereed according to the high standards of the Journal of Physics: Conference Series and the accepted papers illustrate the diversity and the high level of the contributions. Not least significant factor for the success of the 17 ISCMP was the social program, both the organized events (Welcome and Farewell Parties) and the variety of pleasant local restaurants and beaches. Visits to the Archaeological Museum (rich in valuable gold treasures of the ancient Thracian culture) and to the famous rock monastery Aladja were organized for the participants from the Varna Municipality. These Proceedings are published for the second time by the Journal of Physics: Conference Series. We are grateful to the Journal's staff for supporting this idea. The Committee decided that the next event will take place again in Saints Constantine and Helena, 1-5 September 2014. It will be entitled: Challenges of the Nanoscale Science: Theory, Materials and Applications.

The first International Conference on Mathematical Modelling in Physical Sciences (IC-MSQUARE) took place in Budapest, Hungary, from Monday 3 to Friday 7 September 2012. The conference was attended by more than 130 participants, and hosted about 290 oral, poster and virtual papers by more than 460 pre-registered authors. The first IC-MSQUARE consisted of different and diverging workshops and thus covered various research fields in which mathematical modelling is used, such as theoretical/mathematical physics, neutrino physics, non-integrable systems, dynamical systems, computational nanoscience, biological physics, computational biomechanics, complex networks, stochastic modelling, fractional statistics, DNA dynamics, and macroeconomics. The scientific program was rather heavy since after the Keynote and Invited Talks in the morning, two parallel sessions ran every day. However, according to all attendees, the program was excellent with a high level of talks and the scientific environment was fruitful; thus all attendees had a creative time. The mounting question is whether this occurred accidentally, or whether IC-MSQUARE is a necessity in the field of physical and mathematical modelling. For all of us working in the field, the existing and established conferences in this particular field suffer from two distinguished and recognized drawbacks: the first is the increasing orientation, while the second refers to the extreme specialization of the meetings. Therefore, a conference which aims to promote the knowledge and development of high-quality research in mathematical fields concerned with applications of other scientific fields as well as modern technological trends in physics, chemistry, biology, medicine, economics, sociology, environmental sciences etc., appears to be a necessity. This is the key role that IC-MSQUARE will play. We would like to thank the Keynote Speaker and the Invited Speakers for their significant contributions to IC-MSQUARE. We would also

The International Physical Actvity Questionnaire (IPAQ) is a validated tool for physical activity assessment used in many countries however no Arabic version of the long-form of this questionnaire exists to this date. Hence, the aim of this study was to cross-culturally adapt and validate an Arabic version of the long International Physical Activity Questionnaire (AIPAQ) equivalent to the French version (F-IPAQ) in a Lebanese population. The guidelines for cross-cultural adaptation provided by the World Health Organization and the International Physical Activity Questionnaire committee were followed. One hundred fifty-nine students and staff members from Saint Joseph University of Beirut were randomly recruited to participate in the study. Items of the A-IPAQ were compared to those from the F-IPAQ for concurrent validity using Spearman's correlation coefficient. Content validity of the questionnaire was assessed using factor analysis for the A-IPAQ's items. The physical activity indicators derived from the A-IPAQ were compared with the body mass index (BMI) of the participants for construct validity. The instrument was also evaluated for internal consistency reliability using Cronbach's alpha and Intraclass Correlation Coefficient (ICC). Finally, thirty-one participants were asked to complete the A-IPAQ on two occasions three weeks apart to examine its test-retest reliability. Bland-Altman analyses were performed to evaluate the extent of agreement between the two versions of the questionnaire and its repeated administrations. A high correlation was observed between answers of the F-IPAQ and those of the A-IPAQ, with Spearman's correlation coefficients ranging from 0.91 to 1.00 (p < 0.05). Bland-Altman analysis showed a high level of agreement between the two versions with all values scattered around the mean for total physical activity (mean difference = 5.3 min/week, 95% limits of agreement = -145.2 to 155.8). Negative correlations were observed between

Purpose: The purpose of this educational program is to motivate talented, intelligent individuals to become stakeholders in the global effort to improve access to radiotherapy. Methods: The need to improve global access to radiotherapy has been clearly established and several organizations are making substantial progress in securing funding and developing plans to achieve this worthwhile goal. The incorporation of elective international rotations in residency programs may provide one possible mechanism to promote and support this future investment. We recently incorporated an elective 1-month international rotation into our CAMPEP accredited Medical Physics residency program, with our first rotation taking place inmore » Vietnam. A unique aspect of this rotation was that it was scheduled collaboratively with our Radiation Oncology residency program such that Radiation Oncology and Medical Physics residents traveled to the same clinic at the same time. Results: We believe the international rotation substantially enhances the educational experience, providing additional benefits to residents by increasing cross-disciplinary learning and offering a shared learning experience. The combined international rotation may also increase benefit to the host institution by modeling positive multidisciplinary working relationships between Radiation Oncologists and Medical Physicists. Our first resident returned with several ideas designed to improve radiotherapy in resource-limited settings – one of which is currently being pursued in collaboration with a vendor. Conclusion: The elective international rotation provides a unique learning experience that has the potential to motivate residents to become stakeholders in the global effort to improve access to radiotherapy. What better way to prepare the next generation of Medical Physicists to meet the challenges of improving global access to radiotherapy than to provide them with training experiences that motivate them to be

People with schizophrenia typically die over a decade before members of the general population. Physical activity is a low cost and effective intervention that can have a multitude of beneficial effects on people with schizophrenia. Physical therapists lead in the delivery of physical activity in many of the commonly observed co-morbidities in schizophrenia, yet their role in the delivery of physical activity in patients with schizophrenia remains unclear. This study aimed to establish an international consensus on physical therapists' beliefs, potential benefits and practices in the use of physical activity in schizophrenia. All members of the International Organization of Physical Therapists in Mental Health were invited to take part in a cross-sectional online survey. All data were analysed using descriptive statistics and quantitative content and/or thematic analysis. One hundred and fifty-one physical therapists from 31 countries responded. Almost all respondents (92%) felt that physical activity benefited patients with schizophrenia, and 75.2% and 22.5%, respectively, felt that it was very important and important that physical therapists oversee in the delivery of physical activity in psychiatric services. Resultant themes established that physical activity has a plethora of beneficial effects on people with schizophrenia including physical health benefits and biopsychosocial effects such as improved mental health, socialization and quality of life. In addition, participants felt they have the necessary theoretical knowledge and clinical skills required for leading and overseeing physical activity programmes in this complex patient group. Physical therapists identified that physical activity has a plethora of benefits for patients with schizophrenia and that they have the necessary knowledge and skills to lead and oversee the successful delivery of physical activity in patients with schizophrenia in clinical practice.

The Community Healthy Activities Model Program for Seniors (CHAMPS) is a physical activity monitoring questionnaire for people between 65 to 90 years old. This questionnaire has been previously translated to Spanish to be used in the Latin American population. To adapt the Spanish version of the CHAMPS questionnaire to Puerto Rico and assess its internal consistency. An external review committee adapted the existent Spanish version of the CHAMPS to be used in the Puerto Rican population. Three older adults participated in a second phase with the purpose of training the research team. After the second phase, 35 older adults participated in a third content adaptation phase. During the third phase, the preliminary Spanish version for Puerto Rico of the CHAMPS was given to the 35 participants to assess for clarity, vocabulary and understandability. Interviews to each participant in the third phase were carried out to obtain feedback and create a final Spanish version of the CHAMPS for Puerto Rico. After analyses of this phase, the external review committee prepared a final Spanish version of the CHAMPS for Puerto Rico. The final version was administered to 15 older adults (76 +/- 6.5 years) to assess the internal consistency by using Cronbach's Alpha analysis. The questionnaire showed a strong internal consistency of 0.76. The total time to answer the questionnaire was 17.4 minutes. The Spanish version of the CHAMPS questionnaire for Puerto Rico suggested being an easy to administer and consistent measurement tool to assess physical activity in older adults.

The purpose of this study was to determine the test-retest reliability of the International Physical Activity Questionnaire (IPAQ) for older adults in Serbia. Six hundred and sixty older adults (352 men, 53%; 308 women, 47%; mean age 67.65±5.76 years) participated in the study. To examine test-retest reliability, the participants were asked to complete the IPAQ on two occasions 2 weeks apart. Moderate reliability was observed between the repeated IPAQ, with intraclass correlation coefficients ranging from 0.53 to 0.91. The least reliability was established in leisure time activity (0.53) and the most reliability in the transport domain (0.91). Men and women had similar intraclass correlation coefficients for total physical activity (0.71 versus 0.74, respectively), while the biggest difference was obtained for housework in men (0.68) and in women (0.90). Our study shows that the long version of the IPAQ is a reliable instrument for assessing physical activity levels in older adults and that it may be useful for generating internationally comparable data.

The effect of implant removal after internal fixation of a femoral neck fracture on physical functioning was analyzed. Characteristics of patients who had their implant removed were studied, as it is currently unknown from which type of patients implants are removed and what effect removal has on function. Secondary cohort study alongside a randomized controlled trial. Multicenter study in 14 hospitals. Patients who had their implant removed after internal fixation of a femoral neck fracture are compared with patients who did not. Patient characteristics and quality of life (Short Form 12, Western Ontario McMaster Osteoarthritis Index) were compared. Matched pairs were selected based on patient/fracture characteristics and prefracture physical functioning. Of 162 patients, 37 (23%) had their implant removed. These patients were younger (median age: 67 vs. 72 years, P = 0.024) and more often independently ambulatory prefracture (100% vs. 84%, P = 0.008) than patients who did not. They more often had evident implant back-out on x-rays (54% vs. 34%, P = 0.035), possibly related to a higher rate of Pauwels 3 fractures (41% vs. 22%, P = 0.032). In time, quality of life improved more in implant removal patients [+2 vs. -4 points, Short Form 12 (physical component), P = 0.024; +9 vs. 0 points, Western Ontario McMaster Osteoarthritis Index, P = 0.019]. Implant removal after internal fixation of a femoral neck fracture positively influenced quality of life. Implant removal patients were younger and more often independently ambulatory prefracture, more often had a Pauwels 3 fracture, and an evident implant back-out. Implant removal should be considered liberally for these patients if pain persists or functional recovery is unsatisfactory. Therapeutic Level II.

With the advent of compact ultrasound (US) devices, it is easier for physicians to enhance their physical examinations through the use of US. However, although this new tool is widely available, few internal medicine physicians have US training. This study sought to understand physicians' baseline knowledge and skill, provide education in US principles, and demonstrate that proper use of compact US devices is a skill that can be quickly learned. Training was performed at the Mayo Clinic in June 2010 and June 2011. The participants consisted of internal medicine residents. The workshop included didactics and hands-on US experiences with human and cadaver models in a simulation center. Pretests and posttests of residents' knowledge, attitudes, and skills with US were completed. We reassessed the 2010 group in the spring of 2012 with a long-term retention survey for knowledge and confidence in viewing images. A total of 136 interns completed the workshop. Thirty-nine residents completed the long-term retention survey. Posttest assessments showed a statistically significant improvement in the knowledge of US imaging, confidence in identifying structures, image identification, and image acquisition (P < .0001). In the long-term retention study, knowledge of US imaging and confidence in identifying structures did decline. This educational intervention resulted in improvement in US knowledge and image acquisition. However, the knowledge diminished over time, suggesting that further education is needed if US is to become an important component of internal medicine training and practice. © 2014 by the American Institute of Ultrasound in Medicine.

We present a detailed study of the kinematic and physical properties of the ionized gas in multiple knots of the blue compact dwarf galaxy Haro 15. Using echelle and long slit spectroscopy data, obtained with different instruments at Las Campanas Observatory, we study the internal kinematic and physical conditions (electron density and temperature), ionic and total chemical abundances of several atoms, reddening and ionization structure. Applying direct and empirical methods for abundance determination, we perform a comparative analysis between these regions and in their different components. On the other hand, our echelle spectra show complex kinematics in several conspicuous knots within the galaxy. To perform an in-depth 2D spectroscopic study we complete this work with high spatial and spectral resolution spectroscopy using the Integral Field Unit mode on the Gemini Multi-Object Spectrograph instrument at the Gemini South telescope. With these data we are able to resolve the complex kinematical structure within star forming knots in Haro 15 galaxy.

To facilitate a systematic, comprehensive description of functioning and to enable the use of the International Classification of Functioning, Disability and Health (ICF) in clinical practice and research, core sets have been developed. The aim of this study was to propose a version of the ICF core set to classify the physical health of older adults. The proposition of the ICF core set was based on the Delphi technique. The panel of experts included 8 Brazilian researchers (physical therapists, medical doctors, nurses, and physical educators). The communication was wholly electronic. In total, there were 5 rounds of interactivity between the participants to arrive at the final version of the construct. The ICF core set presented 30 categories (14 on body functions, 4 on body structures, 9 on activities or participation, and 3 on environmental factors) and had a Cronbach α of 0.964. The presented core set is a secure, fast, and accurate instrument for assessing the physical health and engagement of older adults. It defines points related to functioning and health that are relevant when evaluating this population, as well as when reevaluating it and monitoring changes.

This paper provides an overview of the microgravity fluid physics and transport phenomena experiments planned for the International Spare Station. NASA's Office of Life and Microgravity Science and Applications has established a world-class research program in fluid physics and transport phenomena. This program combines the vast expertise of the world research community with NASA's unique microgravity facilities with the objectives of gaining new insight into fluid phenomena by removing the confounding effect of gravity. Due to its criticality to many terrestrial and space-based processes and phenomena, fluid physics and transport phenomena play a central role in the NASA's Microgravity Program. Through widely publicized research announcement and well established peer-reviews, the program has been able to attract a number of world-class researchers and acquired a critical mass of investigations that is now adding rapidly to this field. Currently there arc a total of 106 ground-based and 20 candidate flight principal investigators conducting research in four major thrust areas in the program: complex flows, multiphase flow and phase change, interfacial phenomena, and dynamics and instabilities. The International Space Station (ISS) to be launched in 1998, provides the microgravity research community with a unprecedented opportunity to conduct long-duration microgravity experiments which can be controlled and operated from the Principal Investigators' own laboratory. Frequent planned shuttle flights to the Station will provide opportunities to conduct many more experiments than were previously possible. NASA Lewis Research Center is in the process of designing a Fluids and Combustion Facility (FCF) to be located in the Laboratory Module of the ISS that will not only accommodate multiple users but, allow a broad range of fluid physics and transport phenomena experiments to be conducted in a cost effective manner.

Agar-Newman, DJ, Goodale, TL, and Klimstra, MD. Anthropometric and Physical Qualities of International Level Female Rugby Sevens Athletes Based on Playing Position. J Strength Cond Res 31(5): 1346-1352, 2017-The purpose of this study was to profile international level female sevens athletes and determine whether anthropometric and physical qualities are able to differentiate between backs and forwards. Twenty-four subjects with a mean (±SD) age of 22.8 ± 4.0 years and body weight of 69.4 ± 5.2 kg were sampled from a national team training program, ranked in the top 3 on the IRB Women's Sevens World Series. Anthropometric (height, body mass, and sum of 7 skinfolds) and performance measures (power clean, front squat, bench press, neutral grip pull-up, 40-m sprint, and 1,600-m run) were collected across the 2013-2014 centralized period and compared across playing position. The 13 backs (mean age ± SD = 21.3 ± 3.5 years) and 11 forwards (mean age ± SD = 24.5 ± 4.0 years) had significant differences in body mass (66.40 ± 3.48 vs. 72.87 ± 4.79 kg) and initial sprint momentum (366.8 ± 19.8 vs. 399.2 ± 22.4 kg·m·s). However no other measures showed positional differences. The lack of positional differences in female rugby sevens may be due to the multifarious physical requirements of a sevens athlete, leading to a generic athletic profile, or perhaps due to a lack of selective pressure. Also, it is conceivable that the anthropometric and physical qualities measured in this study lacked the necessary precision or failed to capture the unique attributes of each position. In conclusion, this is the first investigation profiling international level female sevens athletes. The normative data presented within this article highlight the physical requirements of female sevens athletes for strength and conditioning practitioners. In addition, the lack of positional differences discovered should impact the training program design.

Physical inactivity and its accompanying adverse sequelae (e.g., obesity and diabetes) are global health concerns. The single most commonly reported physical activity in public health surveys is walking (Centers for Disease Control and Prevention, 2000; Rafferty, Reeves, McGee, & Pivarnik, 2002). As evidence accumulates that walking is important for preventing weight gain (Levine et al., 2008) and reducing the risk of diabetes (Jeon, Lokken, Hu, & van Dam, 2007), there is increased need to capture this behavior in a valid and reliable manner. Although the disadvantages of a self-report methodology are well known (Sallis, & Saelens, 2000), it still represents the most feasible approach for conducting population-level surveillance across developed and developing countries. The International Physical Activity Questionnaire (IPAQ) was created and evaluated as a standardized instrument for this purpose. Although two versions of the IPAQwere designed and evaluated (short: nine items; and long: 31 items), the short form was recommended for population monitoring (Craig et al., 2003). However, it has not been recommended for intervention or research studies that require precise physical activity quantification to examine changes in physical activity at the individual level. IPAQ was also not intended to replace instruments that are more responsive to individual changes in activity level, such as objective measures. In addition to walking behaviors, IPAQ also assesses time spent in moderate- and vigorous-intensity activity as well as sitting behaviors, although the latter is not the focus of this analysis. Aggregated IPAQ data have been previously validated compared to accelerometers, and overall reliability was confirmed across 12 countries (Craig et al., 2003). Previous research showed criterion validity Spearman correlations with a median of 0.30 and test-retest reliability Spearman correlations clustered around 0.8 (Craig et al., 2003). The purpose of this study, however

This volume of Journal of Physics: Conference Series contains the general invited lectures, topical invited lectures and progress reports presented at the 26th Summer School and International Symposium on the Physics of Ionized Gases - SPIG 2012. The conference was held in Zrenjanin, Serbia, from 27-31 August. The SPIG conference has a 52 year long tradition. The structure of the papers in this volume cover the following sections: atomic collision processes, particle and laser beam interactions with solids, low temperature plasmas and general plasmas. As these four topics often overlap and merge in numerous fundamental studies and, more importantly applications, SPIG in general serves as a venue for exchanging ideas in the related fields. We hope that this volume will be an important source of information about progress in plasma physics and will be useful, first of all, for students, but also for plasma physics scientists. The Editors would like to thank the invited speakers for their participation at SPIG 2012 and for their efforts writing contributions for this volume. We also express our gratitude to the members of Scientific and Organizing committees for their efforts in organizing this SPIG. Especially we would like to thank the Ministry of Education, Science and Technological Development of Republic of Serbia, Provincial Secretariat for Science and Techonological Development, Province of Vojvodina, Institute Français de Serbie and Biser Zrenjanin for financial support as well as the European Physical Society (EPS) for supporting the award for the best poster of a young scientist and American Elements, USA.

Despite the known benefits of regular exercise, the reasons why many coronary heart disease (CHD) patients engage in little physical activity are not well understood. This study identifies factors associated with low activity levels in individuals with chronic CHD participating in the STABILITY study, a global clinical outcomes trial evaluating the lipoprotein phospholipaseA2 inhibitor darapladib. Prior to randomization, 15 486 (97.8%) participants from 39 countries completed a lifestyle questionnaire. Total physical activity was estimated from individual subject self-reports of hours spend each week on mild, moderate, and vigorous exercise, corresponding approximately to 2, 4, and 8 METS, respectively. Multivariate logistic regression evaluated clinical and demographic variables for the lowest compared with higher overall exercise levels, and for individuals who decreased rather than maintained or increased activity since diagnosis of CHD. The least active 5280 subjects (34%) reported exercise of ≤ 24 MET.h/week. A total of 7191 subjects (46%) reported less exercise compared with before diagnosis of CHD. The majority of participants were either 'not limited' or 'limited a little' walking 100 m (84%), climbing one flight of stairs (82%), or walking 1 km/1/2; mile (68%), and <10% were limited 'a lot' by dyspnoea or angina. Variables independently associated with both low physical activity and decreasing exercise after diagnosis of CHD included more co-morbid conditions, poorer general health, fewer years of education, race, and country (P < 0.001 for all). In this international study, low physical activity was only partly explained by cardiovascular symptoms. Potentially modifiable societal and health system factors are important determinants of physical inactivity in patients with chronic CHD.

The XXXth International Colloquium on Group Theoretical Methods in Physics (ICGTMP), also known as the Group30 conference, took place in Ghent (Belgium) from Monday 14 to Friday 18 July 2014. The conference was organised by Ghent University (Department of Applied Mathematics, Computer Science and Statistics, and Department of Mathematical Analysis). The website http://www.group30.ugent.be is still available. The ICGTMP is one of the traditional conference series covering the most important topics of symmetry which are relevant to the interplay of present-day mathematics and physics. More than 40 years ago a group of enthusiasts, headed by H. Bacry of Marseille and A. Janner of Nijmegen, initiated a series of annual meetings with the aim to provide a common forum for scientists interested in group theoretical methods. At that time most of the participants belonged to two important communities: on the one hand solid state specialists, elementary particle theorists and phenomenologists, and on the other mathematicians eager to apply newly-discovered group and algebraic structures. The conference series has become a meeting point for scientists working at modelling physical phenomena through mathematical and numerical methods based on geometry and symmetry. It is considered as the oldest one among the conference series devoted to geometry and physics. It has been further broadened and diversified due to the successful applications of geometric and algebraic methods in life sciences and other areas. The first four meetings took place alternatively in Marseille and Nijmegen. Soon after, the conference acquired an international standing, especially following the 1975 colloquium in Nijmegen and the 1976 colloquium in Montreal. Since then it has been organized in many places around the world. It has become a bi-annual colloquium since 1990, the year it was organized in Moscow.

The aim of the study was to examine the construct validity and internal consistency of the Motivational Climate in Physical Education Scale (MCPES). A key element of the development process of the scale was establishing a theoretical framework that integrated the dimensions of task- and ego involving climates in conjunction with autonomy, and social relatedness supporting climates. These constructs were adopted from the self-determination and achievement goal theories. A sample of Finnish Grade 9 students, comprising 2,594 girls and 1,803 boys, completed the 18-item MCPES during one physical education class. The results of the study demonstrated that participants had highest mean in task-involving climate and the lowest in autonomy climate and ego-involving climate. Additionally, autonomy, social relatedness, and task- involving climates were significantly and strongly correlated with each other, whereas the ego- involving climate had low or negligible correlations with the other climate dimensions.The construct validity of the MCPES was analyzed using confirmatory factor analysis. The statistical fit of the four-factor model consisting of motivational climate factors supporting perceived autonomy, social relatedness, task-involvement, and ego-involvement was satisfactory. The results of the reliability analysis showed acceptable internal consistencies for all four dimensions. The Motivational Climate in Physical Education Scale can be considered as psychometrically valid tool to measure motivational climate in Finnish Grade 9 students. Key PointsThis study developed Motivational Climate in School Physical Education Scale (MCPES). During the development process of the scale, the theoretical framework using dimensions of task- and ego involving as well as autonomy, and social relatedness supporting climates was constructed. These constructs were adopted from the self-determination and achievement goal theories.The statistical fit of the four-factor model of the

The VUV conferences series The international conferences on vacuum ultraviolet radiation physics started in 1962, and are now being held every third year. VUV-8 took place at Lund University, August 4-8, 1986. VUV-9 will be arranged at the University of Hawaii, USA, August 14-18, 1989, with Prof. C S Fadley as conference chairman. Chairman of the international advisory board for the period 1986-89 is Prof. L Hedin. The theme of the series can be summarized as experimental and theoretical progress in research fields utilizing the interaction of VUV radiation with matter. The topics cover broad areas within atomic and molecular physics, solid state physics and VUV instrumentation. The conferences emphasize interdisciplinary aspects. To these belong common experimental techniques as, e.g., synchrotron radiation instrumentation, and common theoretical foundations for the description of photon interactions with matter. The VUV-8 conference The VUV-8 conference in Lund was attended by 300 participants from 26 countries. An address list of the participants is given at the end of this volume. There were 33 invited papers given as plenary or key-note talks. As many as 229 posters were presented; 49 of them were also given orally. These numbers are typical for the VUV conferences, except for the number of posters, which was unusually large. In the conference planning the poster sessions were stressed, and particular care was taken to provide a good atmosphere at these sessions. Thus the posters were kept up during the whole conference, coffee was served in the hail with the posters and there were convenient places to sit down close to the posters. Considering the wide scope of the conference it was necessary to emphasize a limited number of topics of high current interest and importance. Thus besides traditional topics, several rapidly expanding fields were discussed in special sessions. At VUV-8 there were the following sessions. Theory of atoms and molecules

Although there are substantial international differences in adolescent physical activity (PA), cross-country motivational differences have received limited attention, perhaps due to the lack of measures applicable internationally. Identical self-report measures assessing PA and motivations for PA were used to survey students ages 11, 13, and 15 from 7 countries participating in the 2005-2006 Health Behavior in School-Aged Children (HBSC) study representing 3 regions: Eastern Europe, Western Europe and North America. Multigroup comparisons with Confirmatory Factor Analysis and Structural Equation Modeling examined the stability of factors across regions and regional differences in relations between PA and motives for PA. Three PA motivation factors were identified as suitable for assessing international populations. There were significant regional, gender, and age differences in relations between PA and each of the 3 PA motives. Social and achievement motives were positively related to PA. However, the association of PA with health motivations varied significantly by region and gender. The patterns suggest the importance of social motives for PA and the possibility that health may not be a reliable motivator for adolescent PA. Programs to increase PA in adolescence need to determine which motives are effective for the particular population being targeted.

The 3rd International Workshop on Statistical Physics and Mathematics for Complex Systems (SPMCS2012) was held between 25-30 August at Kazan (Volga Region) Federal University, Kazan, Russian Federation. This workshop was jointly organized by Kazan Federal University and Institut Supérieur des Matériaux et Mécaniques Avancées (ISMANS), France. The series of SPMCS workshops was created in 2008 with the aim to be an interdisciplinary incubator for the worldwide exchange of innovative ideas and information about the latest results. The first workshop was held at ISMANS, Le Mans (France) in 2008, and the third at Huazhong Normal University, Wuhan (China) in 2010. At SPMCS2012, we wished to bring together a broad community of researchers from the different branches of the rapidly developing complexity science to discuss the fundamental theoretical challenges (geometry/topology, number theory, statistical physics, dynamical systems, etc) as well as experimental and applied aspects of many practical problems (condensed matter, disordered systems, financial markets, chemistry, biology, geoscience, etc). The program of SPMCS2012 was prepared based on three categories: (i) physical and mathematical studies (quantum mechanics, generalized nonequilibrium thermodynamics, nonlinear dynamics, condensed matter physics, nanoscience); (ii) natural complex systems (physical, geophysical, chemical and biological); (iii) social, economical, political agent systems and man-made complex systems. The conference attracted 64 participants from 10 countries. There were 10 invited lectures, 12 invited talks and 28 regular oral talks in the morning and afternoon sessions. The book of Abstracts is available from the conference website (http://www.ksu.ru/conf/spmcs2012/?id=3). A round table was also held, the topic of which was 'Recent and Anticipated Future Progress in Science of Complexity', discussing a variety of questions and opinions important for the understanding of the concept of

Attempts to understand the quantum mechanics of non-Hermitian Hamiltonian systems can be traced back to the early days, one example being Heisenberg's endeavour to formulate a consistent model involving an indefinite metric. Over the years non-Hermitian Hamiltonians whose spectra were believed to be real have appeared from time to time in the literature, for instance in the study of strong interactions at high energies via Regge models, in condensed matter physics in the context of the XXZ-spin chain, in interacting boson models in nuclear physics, in integrable quantum field theories as Toda field theories with complex coupling constants, and also very recently in a field theoretical scenario in the quantization procedure of strings on an AdS5 x S5 background. Concrete experimental realizations of these types of systems in the form of optical lattices have been proposed in 2007. In the area of mathematical physics similar non-systematic results appeared sporadically over the years. However, intensive and more systematic investigation of these types of non- Hermitian Hamiltonians with real eigenvalue spectra only began about ten years ago, when the surprising discovery was made that a large class of one-particle systems perturbed by a simple non-Hermitian potential term possesses a real energy spectrum. Since then regular international workshops devoted to this theme have taken place. This special issue is centred around the 6th International Workshop on Pseudo-Hermitian Hamiltonians in Quantum Physics held in July 2007 at City University London. All the contributions contain significant new results or alternatively provide a survey of the state of the art of the subject or a critical assessment of the present understanding of the topic and a discussion of open problems. Original contributions from non-participants were also invited. Meanwhile many interesting results have been obtained and consensus has been reached on various central conceptual issues in the

This volume of the Journal of Physics: Conference Series contains the Invited lectures, Topical invited lectures and Progress reports presented at the 24th Summer School and International Symposium on the Physics of Ionized Gases - SPIG 2008. The conference was held in Novi Sad, Serbia, 25-29 August 2008. Throughout the history of scientific discovery, one can see repeatedly how fundamental sciences have solved basic questions and opened new frontiers. In the field of physics, there are many key discoveries, resulting in their useful applications for the benefit of the mankind. It is very important to have meetings to discuss actual problems in particular fields of physics. This Conference provided a forum for 160 active researchers from 25 countries to discuss current advances in the physics of ionized gases and related fields. The Conference has a long tradition. Let us remember that the first SPIG was organized in 1968. The decay of former Yugoslavia in 1991, caused a disturbance in SPIG meetings, but fortunately, in 1993, SPIG meetings were successfully revitalized. During recent years we have met successively in Belgrade, Kotor, Zlatibor, Soko Banja, Tara, Kopaonik and finally this time in Novi Sad. The structure of the papers in this Proceedings is as follows: Atomic Collision Processes, Particle and Laser Beam Interactions with Solids, Low Temperature Plasmas and General Plasmas. We hope that this Proceedings will be an important source of information, first of all to students, and also to plasma physics scientists. First of all, we would like to thank to the invited speakers for participating at the SPIG 2008 and for their efforts writing contributions for this Proceedings. We also express our gratitude to the members of the Scientific and Organizing committees for their efforts in organizing the Conference. Especially we would like to thank the Ministry of Science and Technological Development of the Republic of Serbia for financial support. Also, this

Asteroseismic forward modelling techniques are being used to determine fundamental properties (e.g. mass, radius, and age) of solar-type stars. The need to take into account all possible sources of error is of paramount importance towards a robust determination of stellar properties. We present a study of 34 solar-type stars for which high signal-to-noise asteroseismic data is available from multi-year Kepler photometry. We explore the internal systematics on the stellar properties, that is, associated with the uncertainty in the input physics used to construct the stellar models. In particular, we explore the systematics arising from: (i) the inclusion of the diffusion of helium and heavy elements; and (ii) the uncertainty in solar metallicity mixture. We also assess the systematics arising from (iii) different surface correction methods used in optimisation/fitting procedures. The systematics arising from comparing results of models with and without diffusion are found to be 0.5%, 0.8%, 2.1%, and 16% in mean density, radius, mass, and age, respectively. The internal systematics in age are significantly larger than the statistical uncertainties. We find the internal systematics resulting from the uncertainty in solar metallicity mixture to be 0.7% in mean density, 0.5% in radius, 1.4% in mass, and 6.7% in age. The surface correction method by Sonoi et al. and Ball & Gizon's two-term correction produce the lowest internal systematics among the different correction methods, namely, ˜1%, ˜1%, ˜2%, and ˜8% in mean density, radius, mass, and age, respectively. Stellar masses obtained using the surface correction methods by Kjeldsen et al. and Ball & Gizon's one-term correction are systematically higher than those obtained using frequency ratios.

[Purpose] This study aimed to compare basic physical fitness, aerobic capacity, and isokinetic strength between international and national level freestyle high school student swimmers. [Subjects and Methods] A total of 28 participants (14 international level swimmers and 14 national level freestyle high school student swimmers) with no known pathology were included. We used a cross-sectional study to examine three variables: basic physical fitness, aerobic capacity, and isokinetic strength. [Results] The mean values of these variables in the international level swimmers were higher than those in the national level swimmers. Swimmers are generally physically fit with a good competition record. [Conclusion] An appropriate training program, which considers specific individual characteristics is likely to have a positive impact on the improvement of total physical fitness, and subsequently, on the performance of the freestyle high school swimmer.

The international conference ''The Modern Physics of Compact Stars and Relativistic Gravity'' took place in Yerevan, Armenia, from 18-21 September 2013. This was the second in a series of conferences which aim to bring together people working in astrophysics of compact stars, physics of dense matter, gravitation and cosmology, observations of pulsars and binary neutron stars and related fields. The conference was held on the occasion of 100th birthday of the founder of the Theoretical Physics Chair at the Department of Physics of Yerevan State University and prominent Armenian scientist Academician Gurgen S Sahakyan. The field of compact stars has seen extraordinary development since the discovery of pulsars in 1967. Even before this discovery, pioneering work of a number of theoretical groups had laid the foundation for this development. A pioneer of this effort was Professor G S Sahakyan who, together with Professor Victor Ambartsumyan and a group of young scientists, started in the early sixties their fundamental work on the properties of superdense matter and on the relativistic structure of compact stellar objects. This conference explored the vast diversity of the manifestations of compact stars, including the modern aspects of the equation of state of superdense matter, its magnetic and thermal properties, rotational dynamics, superfluidity and superconductivity, phase transition from hadronic to quark matter, etc. The articles on these subjects collected in this volume are evidence of liveliness of the field and of the continuous feedback between theory and the experiment. A part of this volume is devoted to the cosmology and the theories of gravity — the subfields of astrophysics that are of fundamental importance to our understanding of the universe. The reader will find here articles touching on the most diverse aspects of these fields such as modern problems in Einstein's classical theory of gravity and its alternatives, string theory motivated

Generally, operational military duties are associated with a variety of stressors, such as prolonged physical activity (PA). However, limited information is available on the occupational workload or changes in PA during international military operations. Thus, the aim of the study was to investigate the changes in body composition, stress biomarkers, PA, and heart rate (HR) responses of 79 male soldiers during a 6-month international crisis management operation. Measurements were conducted 3 times in South-Lebanon during the operation. Body composition was assessed by the bioelectrical impedance method. Blood samples were analyzed for serum testosterone, sex-hormone binding globulin (SHBG), cortisol and insulin-like growth factor. Saliva sampling was used for analyzing stress biomarkers, cortisol and α-amylase. Heart rate and physical activity were monitored by a recordable belt and tri-axial accelerometer, respectively. Increases in muscle mass (39.2±4.1 vs. 39.5±4.2 kg, p < 0.05) and testosterone (15.9±4.6 vs. 17.2±4 nmol/l, p < 0.01), and reductions in PA variables (e.g., daily step count 9472±2547 vs. 8321±2720, p < 0.05) were observed during the first half (i.e., PRE-MID) of the study. The increase in muscle mass remained significant during the latter half (PRE-POST, 39.2±4.1 vs. 39.6±4.4 kg, p < 0.05), but also fat mass increased (MID-POST, 10.6±4.6 vs. 11.0±4.7 kg, p < 0.05) while SHBG (MID-POST, 31.8±12.1 vs. 26.6±13.2 nmol/l, p < 0.01) and cortisol (MID-POST, 445±116 vs. 400±123 nmol/l, p < 0.05) decreased. With the exception of increased concentration of salivary α-amylase (PRE-POST, 36.5±33.7 vs. 55.1±39.7 U/ml), the acute stress biomarkers and HR responses remained unchanged. Furthermore, the low quantity of PA, low HR values and subjective ratings of exertion refer to rather light physical workload. Due to the operatively calm nature of the working environment, the present soldiers did not express any significant signs of physical

A number of cross-sectional studies have consistently shown a correlation between childhood physical maltreatment, perceived social isolation and internalizing symptoms. Using a longitudinal, three-wave design, this study sought to assess the mediating role of perceived social isolation in adulthood in the association between childhood physical maltreatment and internalizing symptoms in adulthood. The study has a three-wave design. We used data collected from 1994 to 2008 within the framework of the Tromsø Study (N = 4530), a representative prospective cohort study of men and women. Perceived social isolation was measured at a mean age of 54.7 years, and internalizing symptoms were measured at a mean age of 61.7 years. The difference-in-coefficients method was used to assess the indirect effects and the proportion (%) of mediated effects. Childhood physical maltreatment was associated with an up to 68% [relative risk (RR) = 1.68, 95% confidence interval (CI): 1.33-2.13] higher risk of perceived social isolation in adulthood. Childhood physical maltreatment and perceived social isolation in adulthood were associated with greater levels of internalizing symptoms in adulthood (p < 0.01). A dose-response association was observed between childhood physical maltreatment and internalizing symptoms in adulthood (p < 0.001). Perceived social isolation in adulthood mediated up to 14.89% (p < 0.05) of the association between childhood physical maltreatment and internalizing symptoms in adulthood. The results of this study indicate the need to take perceived social isolation into account when considering the impact of childhood physical maltreatment on internalizing symptoms.

This issue contains papers presented at the 15th International Conference on the Physics of Highly Charged Ions, HCI2010. The conference was held at Fudan University, Shanghai, 29 August-3 September 2010. HCI is a biannual conference series going back to the very first conference held in Stockholm, Sweden in 1982. Previous editions in this millennium were held in Berkeley, USA, 2000; Caen, France, 2002; Vilnius, Lithuania, 2004; Belfast, UK, 2006, and Tokyo, Japan, 2008. The physics of highly charged ions, HCIs, is of great interest due to their key role in testing quantum electrodynamics in strong fields, and possible testing of parity non-conservation. However, HCIs also play crucial roles in the physics of hot plasmas, for example those produced in tokamak fusion devices and in inertial confinement fusion experiments. Much of the diagnostics of matter under such extreme environments relies very heavily on high quality atomic data of HCIs. The field of x-ray astronomy hinges almost entirely on the use of spectral lines from HCIs to provide information from distant astrophysical plasmas and objects. Given these fundamental interests and the current rapid developments in fusion and x-ray astronomy, it is clear that the physics of HCIs is a rich area of research with strong and important connections to many important subfields of physics. New application areas of HCI physics are also under development: two examples are (a) to provide 13.5 nm—and later half of this wavelength—radiation for lithography and (b) applications in medical research. The need for high quality atomic data of HCIs is as important now as it has ever been. HCI2010 was attended by over 200 scientists from around 20 countries; see the following table. Over 70 of the participants were students, which is very encouraging for the future of HCI related physics. The academic programme was organized based on the suggestions from the International Advisory Board, and consisted of six review lectures

The ISEE-3 satellite carried out the first extensive exploration of the distant geomagnetic tail during 1983. ISEE-3's orbit was altered with four lunar gravity assists that alternately decreased and increased its orbital energy while keeping the apogees aligned in the antisolar direction. Two spacecraft of the International Solar Terrestrial Physics program will use similar double-lunar swingby orbits to study the solar wind and the geomagnetic environment. Geotail will be built in Japan for the Institute of Space and Astronautical Sciences; its main purpose will be to explore the earth's geomagnetic tail. Wind is a NASA spacecraft that will monitor the solar wind upstream from the earth and will also study the bowshock region of the magnetosphere. Current plans call for launches of both by NASA with expendable launch vehicles during the second half of 1992.

Laser ablation encompasses a wide range of delicate to extreme light interactions with matter that present considerably challenging problems for scientists to study and understand. At the same time, laser ablation also represents a basic process of significant commercial importance in laser material processing—defining a multi-billion dollar industry today. These topics were widely addressed at the 8th International Conference on Laser Ablation (COLA), held in Banff, Canada on 11–16 September 2005. The meeting took place amongst the majestic and natural beauty of the Canadian Rocky Mountains at The Banff Centre, where delegates enjoyed many inspiring presentations and discussions in amore » unique campus learning environment. The conference brought together world leading scientists, students and industry representatives to examine the basic science of laser ablation and improve our understanding of the many physical, chemical and/or biological processes driven by the laser.

The 25th International Conference on Low Temperature Physics (LT25) was hosted by the Kamerlingh Onnes Laboratorium of the Leiden Institute of Physics and held in the RAI Convention Center in Amsterdam, The Netherlands, 6-13 August 2008. It was the second time that the Kamerlingh Onnes Laboratory had the privilege of organizing an LT conference. In 1958, at LT6, 50 years of liquid helium temperatures were commemorated; in 2008 we celebrated the 100th anniversary of the remarkable achievements of Heike Kamerlingh Onnes and his collaborators in Leiden. In 1958 there were 323 participants and 145 papers appeared in the proceedings; in 2008 these numbers had increased to 1390 participants and 900 papers, of which eventually 849 were accepted. This large participation required adequate conference and housing facilities. These could not be found in Leiden, but were conveniently available in Amsterdam. The triennial International Low Temperature Conferences are organized under the auspices of the International Union of Pure and Applied Physics (IUPAP) through Commission C5 on Low Temperature Physics. It is the most important global meeting that brings together the international scientific community in the broad field of Low Temperature Physics. Because the meeting is held only every third year the 11 plenary and 22 half plenary talks (of 45 or 30 min.) generally provide an overview of important new discoveries over the last few years, whereas the 161 short oral presentations (20 min.) are mainly focused on very recent developments. Since the field is broad, embracing a large section of condensed matter physics, the program is divided into five parallel program lines: A. Quantum Gases, Fluids and Solids B. Superconductivity C. Quantum Phase Transitions and Magnetism D. Electronic Quantum Transport in Condensed Matter E. Cryogenic Techniques and Applications This distinction was used both to group the 1625 accepted abstracts, and the short-oral and poster presentations; the

The Low Temperature Microgravity Physics Facility (LTMPF) is a state-of-the-art facility for long duration science Investigations whose objectives can only be achieved in microgravity and at low temperature. LTMPF consists of two reusable, cryogenic facilities with self-contained electronics, software and communication capabilities. The Facility will be first launched by Japanese HIIA Rocket in 2003 and retrieved by the Space Shuttle, and will have at least five months cryogen lifetime on the Japanese Experiment Module Exposed Facility (JEM EF) of the International Space Station. A number of high precision sensors of temperature, pressure and capacitance will be available, which can be further tailored to accommodate a wide variety of low temperature experiments. This paper will describe the LTMPF and its goals and design requirements. Currently there are six candidate experiments in the flight definition phase to fly on LTMPF. Future candidate experiments will be selected through the NASA Research Announcement process. Opportunities for utilization and collaboration with international partners will also be discussed. This work is being carried out by the Jet Propulsion Laboratory, California Institute of Technology under contract to the National Aeronautics and Space Administration. The work was funded by NASA Microgravity Research Division.

During the last four years the UCLA (University of California, Los Angeles) IGPP (Institute of Geophysics and Planetary Physics) Space Plasma Simulation Group has continued its theoretical effort to develop a Mission Oriented Theory (MOT) for the International Solar Terrestrial Physics (ISTP) program. This effort has been based on a combination of approaches: analytical theory, large-scale kinetic (LSK) calculations, global magnetohydrodynamic (MHD) simulations and self-consistent plasma kinetic (SCK) simulations. These models have been used to formulate a global interpretation of local measurements made by the ISTP spacecraft. The regions of applications of the MOT cover most of the magnetosphere: solar wind, low- and high- latitude magnetospheric boundary, near-Earth and distant magnetotail, and auroral region. Most recent investigations include: plasma processes in the electron foreshock, response of the magnetospheric cusp, particle entry in the magnetosphere, sources of observed distribution functions in the magnetotail, transport of oxygen ions, self-consistent evolution of the magnetotail, substorm studies, effects of explosive reconnection, and auroral acceleration simulations. A complete list of the activities completed under the grant follow.

The 5th International Workshop on Top Quark Physics (TOP 2012) took place in Winchester, UK, from the 16-21 September. It gathered students as well as people active in the top quark sector and provided a framework to highlight the newest results and matters related to top quark physics. Discovered in 1995, the top quark is the sixth and heaviest of all quarks, and it is the only one with a lifetime short enough to be observed 'naked'. This makes it an important testing ground in the search for new physics. In fact, the fact of its mass being so much larger than the other quarks, hints at its special role in the Higgs mechanism. For the same reason, in many models of New Physics, new heavy resonances are expected to couple mostly with top quarks. Even if no new particles are observed, the direct correlation between its angular momentum and that of its detectable decay products allows us to probe indirectly New Physics in action when top quarks are created. In this edition of the TOP conference series, for the first time, the agenda was equally balanced between 'traditional' measurements and the now vast number of searches for physics BSM in the top quark sector, thanks mostly to the amount of data collected at the LHC in its Run I. New results were presented by both the Tevatron and the LHC collaborations: improved ttbar and single top cross-section measurements, refined techniques to measure the top quark mass and a large number of results on properties such as spin correlation and W boson polarization in top quark decays were shown. More technical discussions on the experimental issues, both from the detector and the simulation side also took place, drawing together experimentalists and theorists. Reviews of the latest results on ttbar asymmetry both from CDF and D0 and from ATLAS and CMS were shown, and theorists active in the field made some interesting points on this hot topic. Additionally, results on the search for fourth generation fermions and new

To determine the test-retest reliability and validity of the Spanish version of the short-form International Physical Activity Questionnaire (IPAQ) among adults in Mexico. This was a cross-sectional study of a convenience sample of 267 adult factory workers in Mexico City. Participants were 19 - 68 years of age; 48% were female. Participants wore an accelerometer for 9 consecutive days and were administered the Spanish version of the short form IPAQ on two occasions (IPAQ1 and IPAQ2, separated by 9 days). The relation and differences between moderate-to-vigorous physical activity (MVPA) measures obtained from IPAQ1, IPAQ2, and the accelerometer were determined using correlations, linear regression, and paired t-tests. IPAQ1 and IPAQ2 measures of MVPA were significantly correlated to each other (r = 0.55, P < 0.01). However, MVPA was 44 ± 408 minutes/week lower in IPAQ1 than in IPAQ2, although this difference did not reach statistical significance (P = 0.08). The (min/week) measures from IPAQ1 and IPAQ2 were only modestly correlated with the accelerometer measures (r = 0.26 and r = 0.31, P < 0.01), and by comparison to accelerometer measures, MVPA values were higher when based on IPAQ1 (174 ± 357 min/week, P < 0.01) than for IPAQ2 (135 ± 360 min/week, P < 0.01). The percentage of participants who were classified as physically inactive according to the World Health Organization guidelines was 18.0% in IPAQ1, 25.1% in IPAQ2, and 28.2% based on the accelerometer. Similar to what has been observed in other populations, the short form IPAQ has a modest reliability and poor validity for assessing MVPA among Mexican adults.

A design study was completed to explore the theoretical physical capacity (TPC) of the John F. Kennedy International Airport (KJFK) runway system for a northflow configuration assuming impedance-free (to throughput) air traffic control functionality. Individual runways were modeled using an agent-based, airspace simulation tool, the Airspace Concept Evaluation System (ACES), with all runways conducting both departures and arrivals on a first-come first-served (FCFS) scheduling basis. A realistic future flight schedule was expanded to 3.5 times the traffic level of a selected baseline day, September 26, 2006, to provide a steady overdemand state for KJFK runways. Rules constraining departure and arrival operations were defined to reflect physical limits beyond which safe operations could no longer be assumed. Safety buffers to account for all sources of operational variability were not included in the TPC estimate. Visual approaches were assumed for all arrivals to minimize inter-arrival spacing. Parallel runway operations were assumed to be independent based on lateral spacing distances. Resulting time intervals between successive airport operations were primarily constrained by same-runway and then by intersecting-runway spacing requirements. The resulting physical runway capacity approximates a theoretical limit that cannot be exceeded without modifying runway interaction assumptions. Comparison with current KJFK operational limits for a north-flow runway configuration indicates a substantial throughput gap of approximately 48%. This gap may be further analyzed to determine which part may be feasibly bridged through the deployment of advanced systems and procedures, and which part cannot, because it is either impossible or not cost-effective to control. Advanced systems for bridging the throughput gap may be conceptualized and simulated using this same experimental setup to estimate the level of gap closure achieved.

we had an unforgettable experience producing paper sheets ourselves in an old but still operational paper mill in the green enchanting spa of Duszniki Zdrój. A short intensive course in pottery handcraft was also offered to us in the Skansen. Hiking in the rocky labyrinth of Szczeliniec (please try to pronounce this name describing a magnificent cliffed hill with creviced rocks) was also a great adventure. This was followed by a ride on the serpentine Road of a Hundred Turns. And there was another event strongly supported by the local authorities. Two special tutorials on energy research and fusion for young scholars and the general public attracted nearly 200 people. The School was financially supported by the International Centre for Dense Magnetised Plasmas at IPPLM, European Commission, International Atomic Energy Agency, Vienna (Austria), the Abdus Salam International Centre for Theoretical Physics, Trieste (Italy) and the US Department of Energy. We would like to thank cordially our sponsors. Their financial support made it possible for a number of students and teachers to come to Kudowa Zdrój. We are very grateful to Dr Adam Ziembinski, the director of the spa in Kudowa, and his staff for the immense hospitality during our stay. We wish to thank Mr Czeslaw Krecichwost, the mayor of Kudowa Zdrój, for his strong support and interest in the School and help in organizing the lectures for scholars and residents of the region. And our most cordial thanks and gratitude go to Mr Ryszard Panfil for his great kindness, inexhaustible energy and organizational efficiency that helped all of us to enjoy the meeting. We thank all the participants for their contributions and we thank the reviewers of all submitted papers. Thank you for your hard work and co-operation. We are looking forward to the next school and all hope to meet again in Kudowa.

This volume contains the proceedings of the 16th International Conference on the Physics of Highly Charged Ions (HCI 2012) held at the Ruprecht-Karls University in Heidelberg, Germany, 2-7 September 2012 (figure 1). This conference has been part of a biannual conference series that was started in Stockholm in 1982 and, since then, has been organized at various places around the world, with recent venues in Belfast (UK, 2006), Tokyo (Japan, 2008) and Shanghai (China, 2010). The physics of highly charged ions (HCI) is a rapidly developing and attractive field of research with impact upon many other research disciplines. Apart from fundamental studies on the structure and dynamics of matter in extreme fields, or the search for physics beyond the standard model, detailed knowledge about the properties and behavior of HCI is crucial for other areas, from astro- and solar physics to hot plasma and fusion research to extreme ultra-violet and ion lithography, or even to medical research, to name just a few. In fusion research, for example, of whether tokamak, stellarator or confinement fusion facilities, most models and diagnostics deeply rely on the understanding of HCI and the (theoretical) prediction of accurate atomic data for these systems. In life science, moreover, ion therapy or the laser acceleration of ions and electrons may help save and improve the quality of life in the future. Many of these and further topics are addressed in these proceedings. After 30 years, the HCI conference series, and especially the meeting in Heidelberg, is appreciated much as a key forum for bringing together senior experts with students, young researchers and scientists from related disciplines who make use and give back impact upon the research with HCI. More than 250 scientists from 23 countries participated in HCI 2012 and presented the current status of the field. About one third of them were post-graduate students, showing that the field attracts many young and talented

This volume contains the Proceedings of the 14th International Conference on the Physics of Highly Charged Ions (HCI2008), held at the University of Electro-Communications, Chofu, Tokyo, Japan from 1-5 September 2008. This series of conferences began in Stockholm, Sweden in 1982 and has since been held every other year; in Oxford, UK (1984), Groningen, the Netherlands (1986), Grenoble, France (1988), Giessen, Germany (1990), Manhattan, Kansas, USA (1992), Vienna, Austria (1994), Omiya, Japan (1996), Bensheim, Germany (1998), Berkeley, USA (2000), Caen, France (2002), Vilnius, Lithuania (2004) and Belfast, UK (2006). Highly charged ions (HCI), which are defined as highly ionized (i.e. positively charged atomic) ions here, mainly exist in hot plasmas such as the solar corona and fusion plasmas. It is true that its importance in plasma physics has driven researchers to the spectroscopic studies of HCIs, but the spectroscopy of few-electron ions is not only important for plasmas but also interesting for fundamental atomic physics. Electrons moving fast near a heavy nucleus give a suitable system to test the fundamental atomic theory involving relativistic and quantum electro-dynamic effects in a strong field. Also, the huge potential energy of a HCI induces drastic reaction in the interaction with matter. This unique property of HCIs, coupled with the recent development of efficient ion sources, is opening the possibility to utilize them in new technologies in the field such as nano-fabrication, surface analysis, medical physics, and so on. Hence, this conference is recognized as a valuable gathering place for established practitioners and also for newcomers; we exchange information, we are introduced to the subject itself, and to unexpected interfaces with other fields. On 31 August, the day before the opening of HCI2008, we welcomed the delegates at the university's restaurant—and we were greeted with an unusually heavy summer shower! The conference then opened on

The aim of this study was to survey the level of self-reported physical activity in people with type 2 diabetes, with and without peripheral neuropathy. A sample of South Australian adults (n=481) 33 to 88 years of age who had type 2 diabetes, including 55 people with peripheral neuropathy, completed the International Physical Activity Questionnaire (IPAQ). Levels of self-reported physical activity were compared between those with and without peripheral neuropathy. People with type 2 diabetes and peripheral neuropathy (median [Mdn]=1433; interquartile range [IQR]=495 to 3390 metabolic equivalent minutes per week [MET-min/wk]) were less physically active than those without peripheral neuropathy (Mdn=2106; IQR=876 to 4380 MET-min/wk) (p=0.04). A total of 49% of people with type 2 diabetes and peripheral neuropathy met physical activity recommendations of 150 minutes of at least moderate activity per week, compared to 57% of people with type 2 diabetes alone. These findings demonstrate that people with type 2 diabetes and peripheral neuropathy reported being significantly less active than people with type 2 diabetes alone. People with type 2 diabetes and peripheral neuropathy need to be encouraged to perform higher levels of physical activity for biologic, physical and psychological benefits. Further studies using objective measures of physical activity are required to support these results. Copyright Â© 2016 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

Calibration of physically-based distributed hydrologic models has always been a challenging task and subject of controversy in the literature. This study is aimed to investigate how different physiographic characteristics of watersheds call for adaption of the methods used in order to have more robust and internally justifiable simulations. Haw Watershed (1300 sq. mi.) is located in the piedmont region of North Carolina draining into B. Everett Jordan Lake located in west of Raleigh. Major land covers in this watershed are forest (50%), urban/suburban (21%) and agriculture (25%) of which a large portion is pasture. Different hydrologic behaviors are observed in this watershed based on the land use composition and size of the sub-watersheds. Highly urbanized sub-watersheds show flashier hydrographs and near instantaneous hydrologic responses. This is also the case with smaller sub-watersheds with relatively lower percentage of urban areas. The Soil and Water Assessment Tool (SWAT) has been widely used in the literature for hydrologic simulation on daily basis using Soil Conservation Service Curve Number method (SCS CN). However, it has not been used as frequently using the sub-daily routines. In this regard there are a number of studies in the literature which have used coarse time scale (daily) precipitation with methods like SCS CN to calibrate SWAT for watersheds containing different types of land uses and soils reporting satisfying results at the outlet of the watershed. This is while for physically-based distributed models, the more important concern should be to check and analyze the internal processes leading to those results. In this study, the watershed is divided into several sub-watersheds to compare the performance of SCS CN and Green & Ampt (GA) methods on different land uses at different spatial scales. The results suggest better performance of GA compared to SCS CN for smaller and highly urbanized sub-watersheds although GA predominance is not very

Patient care is 1 of the 6 core competencies defined by the Accreditation Council for Graduate Medical Education (ACGME). The physical examination (PE) is a fundamental skill to evaluate patients and make an accurate diagnosis. The purpose of this study was to investigate 3 different methods to teach PE skills and to assess the ability to do a complete PE in a simulated patient encounter. Prospective, uncontrolled, observational. Northeastern academic medical center. A total of 32 orthopedic surgery residents participated and were divided into 3 didactic groups: Group 1 (n = 12) live interactive lectures, demonstration on standardized patients, and textbook reading; Group 2 (n = 11) video recordings of the lectures given to Group 1 and textbook reading alone; Group 3 (n = 9): 90-minute modules taught by residents to interns in near-peer format and textbook reading. The overall score for objective structured clinical examinations from the combined groups was 66%. There was a trend toward more complete PEs in Group 1 taught via live lectures and demonstrations compared to Group 2 that relied on video recording. Near-peer taught residents from Group 3 significantly outperformed Group 2 residents overall (p = 0.02), and trended toward significantly outperforming Group 1 residents as well, with significantly higher scores in the ankle (p = 0.02) and shoulder (p = 0.02) PE cases. This study found that orthopedic interns taught musculoskeletal PE skills by near-peers outperformed other groups overall. An overall score of 66% for the combined didactic groups suggests a baseline deficit in first-year resident musculoskeletal PE skills. The PE should continue to be taught and objectively assessed throughout residency to confirm that budding surgeons have mastered these fundamental skills before going into practice.

The psychometric profiles of the widely used International Physical Activity Questionnaire-Short Form (IPAQ-SF) in Chinese youth have not been reported. The purpose of this study was to examine the validity and reliability of the IPAQ-SF using a sample of Chinese youth. One thousand and twenty-one youth (M(age) = 14.26 +/- 1.63 years, 52.8% boys) from 11 cities in China wore accelerometers for 7 consecutive days and completed the IPAQ-SF on the 8th day to recall their physical activity (PA) during accelerometer-wearing days. A subsample of 92 youth (M(age) = 15.90 +/- 1.35 years, 46.7% boys) completed the IPAQ-SF again a week later to recall their PA during accelerometer-wearing days. Differences in PA estimated by the IPAQ-SF and accelerometer were examined by paired-sample t test. Spearman correlation coefficients were used to examine the correlation between the IPAQ-SF and accelerometer. Test-retest reliability of the IPAQ-SF was determined by the intraclass correlation coefficient (ICC). Compared with accelerometer, the IPAQ-SF overestimated sedentary time, moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA). Correlations between PA (total PA, MPA, VPA, and MVPA) and sedentary time measured by 2 instruments ranged from "none" to "low" (p = .08-.31). Test-retest ICC of the IPAQ-SF ranged from "moderate" to "high" (ICC = .43-.83), except for sitting in boys (ICC = .06), sitting for the whole sample (ICC = .32), and VPA in girls (ICC = .35). The IPAQ-SF was not a valid instrument for measuring PA and sedentary behavior in Chinese youth.
During a reaccreditation visit, deficiencies were discovered in the clinical education curriculum regarding patient-centered care in a Doctorate of Physical Therapy program. To understand the problem and address those deficiencies, the clinical internship experience was examined using the International Classification of Functioning, Disability, and Health (ICF) model as a conceptual framework for clinical reasoning. This qualitative case study aimed to study (1) perceptions of physical therapy (PT) students regarding their knowledge and learning experiences during clinical affiliations and what knowledge they acquired of the ICF as applied to patient-centered care during their internship, and (2) the perceptions of clinical instructors (CIs) of their knowledge of the ICF model, its integration into their practice, barriers to its use, and the learning experiences the CIs provided to students regarding the ICF model. Data were collected using questionnaires sent to 42 CIs and at focus groups of 22 PT students conducted at the study site. Data were also collected from student evaluations on the Clinical Performance Instrument. Data were analyzed using coding techniques and themes based on the use of the ICF model in the clinical setting by students and CIs. Most CIs reported a poor understanding of the ICF model or how it relates to patient-centered care; both CIs and students reported none to minimal learning experience related to the ICF model. Document analysis of the student evaluations revealed no assessment of the ICF model was mentioned.

The International Conference on Computing in High Energy and Nuclear Physics (CHEP) was held at Academia Sinica in Taipei from 18-22 October 2010. CHEP is a major series of international conferences for physicists and computing professionals from the worldwide High Energy and Nuclear Physics community, Computer Science, and Information Technology. The CHEP conference provides an international forum to exchange information on computing progress and needs for the community, and to review recent, ongoing and future activities. CHEP conferences are held at roughly 18 month intervals, alternating between Europe, Asia, America and other parts of the world. Recent CHEP conferences have been held in Prauge, Czech Republic (2009); Victoria, Canada (2007); Mumbai, India (2006); Interlaken, Switzerland (2004); San Diego, California(2003); Beijing, China (2001); Padova, Italy (2000) CHEP 2010 was organized by Academia Sinica Grid Computing Centre. There was an International Advisory Committee (IAC) setting the overall themes of the conference, a Programme Committee (PC) responsible for the content, as well as Conference Secretariat responsible for the conference infrastructure. There were over 500 attendees with a program that included plenary sessions of invited speakers, a number of parallel sessions comprising around 260 oral and 200 poster presentations, and industrial exhibitions. We thank all the presenters, for the excellent scientific content of their contributions to the conference. Conference tracks covered topics on Online Computing, Event Processing, Software Engineering, Data Stores, and Databases, Distributed Processing and Analysis, Computing Fabrics and Networking Technologies, Grid and Cloud Middleware, and Collaborative Tools.

Comparison between the International Physical Activity Questionnaire and the American College of Sports Medicine/American Heart Association criteria to classify the physical activity profile in adults.
de Moraes, Suzana Alves; Suzuki, Cláudio Shigueki; de Freitas, Isabel Cristina Martins
the study aims to evaluate the reproducibility between the International Physical Activity Questionnaire and the American College of Sports Medicine/American Heart Association criteria to classify the physical activity profile in an adult population living in Ribeirão Preto, SP, Brazil. population-based cross-sectional study, including 930 adults of both genders. The reliability was evaluated by Kappa statistics, estimated according to socio-demographic strata. the kappa estimates showed good agreement between the two criteria in all strata. However, higher prevalence of "actives" was found by using the American College of Sports Medicine/American Heart Association. although the estimates have indicated good agreement, the findings suggest caution in choosing the criteria to classify physical activity profile mainly when "walking" is the main modality of physical activity.

Given the importance of regular physical activity, it is crucial to evaluate the factors favoring participation in physical activity. We aimed to report the psychometric analysis of the Farsi version of the Physical Activity and Leisure Motivation Scale (PALMS). The Farsi version of PALMS was completed by 406 healthy adult individuals to test its factor structure and concurrent validity and reliability. Conducting the exploratory factor analysis revealed nine factors that accounted for 64.6% of the variances. The PALMS reliability was supported with a high internal consistency of 0.91 and a high test-retest reliability of 0.97 (95% CI: 0.97-0.98). The association between the PALMS and its previous version Recreational Exercise Motivation Measure scores was strongly significant (r= 0.86, P < 0.001). We have shown that the Farsi version of the PALMS appears to be a valuable instrument to measure motivation for physical activity and leisure.
The XIII International Conference on Calorimetry in High Energy Physics was held in Pavia, Italy, 26-30 May 2008, picking up the baton from the 2006 Conference in Chicago. The Conference took place in the unique environment of the Theresian Room of the University Library. The attendees were surrounded by over 40 000 books of general interest and culture, and had the opportunity to see precious volumes written by such people as Galileo, Volta and Faraday. The Workshop brought together more than 120 participants, including senior scientists as well as young physicists, confirming the central and ever-growing role of calorimeters in modern particle physics. The development of these detectors, as stressed by Professor Klaus Pretzl in his lectio magistralis, has made it possible to explore new frontiers in physics, and the present scenario is no exception to this rule. With the LHC experiments almost completely installed and ready to take data, the Conference was an ideal chance to review the status of the different projects, whose development has been followed and discussed throughout the entire Calor series, and to show that they are capable of meeting the design specifications. Other highlights were the performance and physics results of calorimeters installed in currently operating experiments. In the session on astrophysics and neutrinos, the contributions confirmed the key role of calorimeters in this sector and demonstrated their growing application even beyond the field of accelerator physics. Considerable time was devoted to the state-of-the-art techniques in the design and operation of the detectors, while the session on simulation addressed the importance of a thorough understanding of the shower development to meet the demanding requirements of present experiments. Finally, on the R&D side, the particle flow and dual read-out concepts confronted the challenges issued by the next generation of experiments. This complex material was reviewed in 83

To investigate the physical qualities that differentiate playing minutes in international-level women's rugby sevens players. Twenty-four national-level female rugby sevens players underwent measurements of anthropometry, acceleration, speed, lower- and upper-body strength, lower-body power, and aerobic fitness. Playing minutes in international competition were used to differentiate players into 2 groups, a high- or low-playing-minutes group. Playing minutes were related to team selection, which was determined by the coaching staff. Playing minutes were therefore used to differentiate performance levels. Players in the high-playing-minutes group (≥70 min) were older (mean ± SD 24.3 ± 3.1 vs 21.2 ± 4.3 y, P = .05, effect size [ES] = 0.77 ± 0.66, 90% confidence limit) and had greater experience in a national-training-center environment (2.4 ± 0.8 vs 1.7 ± 0.9 y, P = .03, ES = 0.83 ± 0.65), faster 1600-m time (374.5 ± 20.4 vs 393.5 ± 29.8 s, P = .09, ES = -0.70 ± 0.68), and greater 1-repetition-maximum upper-body strength (bench press 68.4 ± 6.3 vs 62.2 ± 8.1 kg, P = .07, ES = 0.80 ± 0.70, and neutral-grip pull-up 84.0 ± 8.2 vs 79.1 ± 5.4 kg, P = .12, ES = 0.68 ± 0.72) than athletes who played fewer minutes. Age (rs = .59 ± ~.28), training experience (rs = .57 ± ~.29), bench press (r = .44 ± ~.36), and 1600-m time (r = -.43 ± ~.34) were significantly associated with playing minutes. Neutral-grip pull-up and bench press contributed significantly to a discriminant analysis. The average squared canonical correlation was .46. The discriminant analysis predicted 7 of 9 and 6 of 10 high- and low-playing-minutes athletes, respectively. Age, training experience, upper-body strength, and aerobic fitness differentiated athlete playing minutes in international women's rugby sevens.

The International Conference on Computing in High Energy and Nuclear Physics (CHEP) is a major series of international conferences intended to attract physicists and computing professionals to discuss on recent developments and trends in software and computing for their research communities. Experts from the high energy and nuclear physics, computer science, and information technology communities attend CHEP events. This conference series provides an international forum to exchange experiences and the needs of a wide community, and to present and discuss recent, ongoing, and future activities. At the beginning of the successful series of CHEP conferences in 1985, the latest developments in embedded systems, networking, vector and parallel processing were presented in Amsterdam. The software and computing ecosystem massively evolved since then, and along this path each CHEP event has marked a step further. A vibrant community of experts on a wide range of different high-energy and nuclear physics experiments, as well as technology explorer and industry contacts, attend and discuss the present and future challenges, and shape the future of an entire community. In such a rapidly evolving area, aiming to capture the state-of-the-art on software and computing through a collection of proceedings papers on a journal is a big challenge. Due to the large attendance, the final papers appear on the journal a few months after the conference is over. Additionally, the contributions often report about studies at very heterogeneous statuses, namely studies that are completed, or are just started, or yet to be done. It is not uncommon that by the time a specific paper appears on the journal some of the work is over a year old, or the investigation actually happened in different directions and with different methodologies than originally presented at the conference just a few months before. And by the time the proceedings appear in journal form, new ideas and explorations have

Physical activity (PA) seems to be important for long-term weight loss after bariatric surgery; however, studies provide evidence for insufficient PA levels in bariatric patients. Research found self-efficacy to be associated with PA and weight bias internalization, for which an influence on mental and physical health has been shown in recent studies. The purpose of the present study was to investigate the influence of general self-efficacy on PA, mediated by weight bias internalization. In 179 bariatric surgery candidates, general self-efficacy, weight bias internalization, and different intensities of PA were assessed by self-report questionnaires. Structural equation modeling was used to analyze the assumed mediational relationship. After controlling for sociodemographic variables, weight bias internalization fully mediated the association between general self-efficacy and moderate-intense as well as vigorous-intense PA. Lower general self-efficacy predicted greater weight bias internalization, which in turn predicted lower levels of moderate-intense and vigorous-intense PA. The results suggest an influence of weight bias internalization on preoperative PA in bariatric surgery candidates. Subsequently, implementation of interventions addressing weight bias internalization in the usual treatment of bariatric surgery candidates might enhance patients' preoperative PA, while longitudinal analyses are needed to further examine its predictive value on PA after bariatric surgery.

The hearts of sports fans were stirred recently by the fastest-ever try scored in international rugby. Welsh winger Dafydd Howells crossed the Fijian try line to score a mere six seconds after Angus O'Brien had started the game with a kickoff, in one of the fixtures in rugby's Junior World Cup played on June 2, 2014, in New Zealand. This startlingly quick score, though, is of interest to physics players as well as rugby players. Howells' try serves as an intriguing way to involve students in one of the "core competencies" of physicists—to model events in the real world. And with the Rugby World Cup taking place in 2015 in England, and rugby sevens making its debut in the 2016 Summer Olympics in Brazil (U.S. teams have qualified for both events), rugby is increasing in popularity in America and is even gaining some coverage on television. Thanks to You-Tube, Howells' try is readily available to serve as a laboratory experiment for students to analyze.

The far ultraviolet (FUV) imager for the International Solar Terrestrial Physics (ISTP) mission is designed to image four features of the aurora: O I lines at 130.4 nm and 135.6 nm and the N2 Lyman-Birge-Hopfield (LBH) bands between 140 nm - 160 nm (LBH long) and 160 nm - 180 nm (LBH long). In this paper we report the design and fabrication of narrow-band and broadband filters for the ISTP FUV imager. Narrow-band filters designed and fabricated for the O I lines have a bandwidth of less than 5 nm and a peak transmittance of 23.9 percent and 38.3 percent at 130.4 nm and 135.6 nm, respectively. Broadband filters designed and fabricated for LBH bands have the transmittance close to 60 percent. Blocking of out-of-band wavelengths for all filters is better than 5x10(exp -3) percent with the transmittance at 121.6 nm of less than 10(exp -6) percent.

The XVIth International Conference on Calorimetry in High Energy Physics - CALOR 2014 - was held in Giessen, Germany from 6-11 April 2014 at the Science Campus of the University. It was hosted by the Justus-Liebig-University and the HIC for FAIR Helmholtz International Center. The series of conferences on calorimetry were started in 1990 at Fermilab and are focusing primarily on operating and future calorimeter systems within the Hadron and High-Energy Physics community without neglecting the impact on other fields such as Astrophysics or Medical Imaging. Confirmed by the impressive list of over 70 oral presentations, 5 posters and over 100 attendees, the field of calorimetry appears alive and attractive. The present volume contains the written contributions of almost all presentations which can be found at http://calor2014.de. Time slots of 15 or 30 minutes including discussion were allocated. The conference was accompanied by a small exhibition of several industrial companies related to the field. The day before the opening of the scientific program, Richard Wigmans gave an excellent and vivid tutorial on basic aspects on calorimetry meant as an introduction for students and conference attendees new in the field. The opening ceremony was used to give an impression of the present and future status and the scientific program of the new FAIR facility nearby at Darmstadt presented by Klaus Peters from GSI. The conference program of the first day was dedicated to the performance and required future upgrade of the LHC experiments, dominated by ATLAS, CMS and LHCb. The program of the next day contained specific aspects on electronics and readout as well as calorimetry in outer space. Several contributions discussed in detail new concepts for hadron calorimeters within the CALICE collaboration completed by a session on sampling calorimeters. The next sections were dedicated to operating and future calorimeters at various laboratories and covering a wide range of

The ninth meeting of the TAUP Workshop Series, TAUP 2005, was organized by the University of Zaragoza and Laboratorio Subterráneo de Canfranc, jointly with the Laboratori Nazionali del Gran Sasso of the Italian Institute of Nuclear Physics (INFN). It was dedicated to the memory of professor Angel Morales, co-founder of the TAUP Series and a central figure in the scientific shaping and organization of the TAUP conferences since their inception in 1989. He and his group of collaborators laid, twenty years ago, the foundations of underground physics in Spain. To have TAUP 2005 hosted by the University of Zaragoza was a tangible way of honouring his memory. The Conference was concluded by a visit to the new installations of the Canfranc Laboratory, where a memorial ceremony was held in honour of Angel Morales, the driving force for the creation of that Laboratory. In TAUP 2005 all the various aspects of Astroparticle Physics have been covered, from Cosmology and Dark Constituents, to Gravitational Waves, to Neutrino Physics and Astrophysics, to High Energy Astrophysics, to Cosmic Rays and Gamma-Rays Astronomy. New and important scientific results were presented and debated in the plenary review talks and in a very large number of contributions in topical parallel sessions. As editors of these proceedings, we hope that this volume, which contains most of the talks and contributions presented at TAUP 2005, will provide a detailed state-of-the-art account of the various facets of Astroparticle Physics. We thank all the invited speakers and contributors who made this possible. Full coverage of the transparencies presented at the conference can be found on the website http://www.unizar.es/taup2005. At TAUP 2005 a memorial lecture was delivered by Art McDonald to commemorate John Bahcall, who passed away prematurely in August 2005. In this talk, his figure, as a pioneer and leader in the fields of Neutrino Physics, Astronomy and Astrophysics and as a man of great personal

The Comprehensive ICF Core Set for vocational rehabilitation (VR) is a list of essential categories on functioning based on the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF), which describes a standard for interdisciplinary assessment, documentation, and communication in VR. The aim of this study was to examine the content validity of the Comprehensive ICF Core Set for VR from the perspective of physical therapists. A 3-round email survey was performed using the Delphi method. A convenience sample of international physical therapists working in VR with work experience of ≥2 years were asked to identify aspects they consider as relevant when evaluating or treating clients in VR. Responses were linked to the ICF categories and compared with the Comprehensive ICF Core Set for VR. Sixty-two physical therapists from all 6 WHO world regions responded with 3,917 statements that were subsequently linked to 338 ICF categories. Fifteen (17%) of the 90 categories in the Comprehensive ICF Core Set for VR were confirmed by the physical therapists in the sample. Twenty-two additional ICF categories were identified that were not included in the Comprehensive ICF Core Set for VR. Vocational rehabilitation in physical therapy is not well defined in every country and might have resulted in the small sample size. Therefore, the results cannot be generalized to all physical therapists practicing in VR. The content validity of the ICF Core Set for VR is insufficient from solely a physical therapist perspective. The results of this study could be used to define a physical therapy-specific set of ICF categories to develop and guide physical therapist clinical practice in VR. © 2016 American Physical Therapy Association.

This volume contains contributed papers from the 7th international conference on 'Applications of Physics in Financial Analysis (APFA)' held at Tokyo on 1-5 March 2009. The conference was organized jointly by Tokyo Institute of Technology and Hitotsubashi University with support from the Research Institute of Economy, Trade, and Industry (RIETI), Physical Society of Japan, Japanese Economic Association, Information Processing Society of Japan, Japanese Society for Artificial Intelligence, and Japan Association for Evolutionary Economics. The first APFA conference (APFA1) was held in 1999 at Dublin, followed by APFA2 at Liege in 2000, APFA3 at London in 2001, APFA4 at Warsaw in 2003, APFA5 at Torino in 2006, and APFA6 at Lisbon in 2007. The 7th APFA conference, which is the first meeting held outside Europe, was attended by 223 researchers in physics and economics from 23 countries world-wide. In keeping with past APFA conferences, we paid special attention to issues in financial markets, which turned out to be very timely. The conference was held in March 2009, in the middle of the global financial crisis that originally started in the US and spread quickly to every corner of the world. The topic of the conference is 'New Approaches to the Analysis of Large Scale Business and Economic data'. The rapid development of information and communication technology has enabled financial/non-financial firms to keep detailed records of their business activities in the form of, for example, tick-by-tick data in financial markets, point-of-sale (POS) data on individual household's purchasing activity, and interfirm network data describing relationships among firms in terms of suppliers/customers transactions and ownerships. This growth in the scope and amount of business data available to researchers has led to a far-reaching expansion in research possibilities. Researchers not only in social sciences but also in physics, mathematics, and information sciences have recently
The National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) International Solar-Terrestrial Physics (ISTP) Program is committed to the development of a comprehensive, multi-mission ground data system which will support a variety of national and international scientific missions in an effort to study the flow of energy from the sun through the Earth-space environment, known as the geospace. A major component of the ISTP ground data system is an ISTP-dedicated Central Data Handling Facility (CDHF). Acquisition, development, and operation of the ISTP CDHF were delegated by the ISTP Project Office within the Flight Projects Directorate to the Information Processing Division (IPD) within the Mission Operations and Data Systems Directorate (MO&DSD). The ISTP CDHF supports the receipt, storage, and electronic access of the full complement of ISTP Level-zero science data; serves as the linchpin for the centralized processing and long-term storage of all key parameters generated either by the ISTP CDHF itself or received from external, ISTP Program approved sources; and provides the required networking and 'science-friendly' interfaces for the ISTP investigators. Once connected to the ISTP CDHF, the online catalog of key parameters can be browsed from their remote processing facilities for the immediate electronic receipt of selected key parameters using the NASA Science Internet (NSI), managed by NASA's Ames Research Center. The purpose of this paper is twofold: (1) to describe how the ISTP CDHF was successfully implemented and operated to support initially the Japanese Geomagnetic Tail (GEOTAIL) mission and correlative science investigations, and (2) to describe how the ISTP CDHF has been enhanced to support ongoing as well as future ISTP missions. Emphasis will be placed on how various project management approaches were undertaken that proved to be highly effective in delivering an operational ISTP CDHF to the Project on schedule and

Scientists migrate for a variety of reasons: political problems with their governments, lack of professional opportunities in their countries, the lure of better lives, financial security for them and their families, better education for their off-springs, and so forth. Migration usually occurs from poor and oppressed countries--the two categories are not one and the same--to the rich and the open. It has created, over time, a dilemma for the poor countries: in the midst of all their other problems, how to justify spending on higher education and research when that investment often results in the most enterprising of its citizens to leave their countries behind? (When migration has reversed direction occasionally, it is because of certain necessities of the scientists to be back in their countries or for opportunities that some individuals see for wielding greater scientific power.) The ideal of keeping the best scientists in their own countries, still ensuring that they remain scientifically productive and inspiring to the youth, is what provided the motivation for the creation of the International Centre for Theoretical Physics in Trieste, Italy, where I served as Director for some seven years. In this talk, I will present the story behind the formation of the Centre in 1964, explain its rationale, and analyze its evolution over time to accommodate the changing scene in world; I will discuss how some things have remained the same even as more of them have changed over time. Finally, I will remark on the broad needs of developing countries even though such needs are often very specific to a country.

Overview of Experiments to Study the Physics of Fast Reactors Represented in the International Directories of Critical and Reactor Experiments John D. Bess Idaho National Laboratory Jim Gulliford, Tatiana Ivanova Nuclear Energy Agency of the Organisation for Economic Cooperation and Development E.V.Rozhikhin, M.Yu.Sem?nov, A.M.Tsibulya Institute of Physics and Power Engineering The study the physics of fast reactors traditionally used the experiments presented in the manual labor of the Working Group on Evaluation of sections CSEWG (ENDF-202) issued by the Brookhaven National Laboratory in 1974. This handbook presents simplified homogeneous model experiments with relevant experimental data, as amended. The Nuclear Energymore » Agency of the Organization for Economic Cooperation and Development coordinates the activities of two international projects on the collection, evaluation and documentation of experimental data - the International Project on the assessment of critical experiments (1994) and the International Project on the assessment of reactor experiments (since 2005). The result of the activities of these projects are replenished every year, an international directory of critical (ICSBEP Handbook) and reactor (IRPhEP Handbook) experiments. The handbooks present detailed models of experiments with minimal amendments. Such models are of particular interest in terms of the settlements modern programs. The directories contain a large number of experiments which are suitable for the study of physics of fast reactors. Many of these experiments were performed at specialized critical stands, such as BFS (Russia), ZPR and ZPPR (USA), the ZEBRA (UK) and the experimental reactor JOYO (Japan), FFTF (USA). Other experiments, such as compact metal assembly, is also of interest in terms of the physics of fast reactors, they have been carried out on the universal critical stands in Russian institutes (VNIITF and VNIIEF) and the US (LANL, LLNL, and others.).

The 17th edition of the International Conference on the Physics of Highly Charged Ions (HCI 2014) was held in San Carlos de Bariloche, in the southern region of Argentina known as Patagonia, from August 31 to September 5, 2014. This meeting corresponds to a series of HCI conferences, which has been held every other year since 1982 in cities in Europe, USA, Japan and China. This was the first time that the conference took place in Latin America. This edition was organized by a Local Committee made up of physicists mainly from the cities of Bariloche and Rosario and also from Buenos Aires and Bahía Blanca, all sites where research on Atomic Collisions is developed. The conference was attended by delegates coming from 18 countries, more that 23% of whom were women. The field of highly charged ions has seen in recent years a promising evolution originating from bold progress in theory and significant advances in experimental techniques. The HCI conferences aim at bringing together experimentalists and theoreticians from as wide a range of fields as, for instance, Fundamental Aspects, Structure and Spectroscopy, Collisions with Electrons, Ions, Atoms and Molecules, Interaction with Clusters, Surfaces and Solids, Interactions with Photons and Plasmas, Strong Field Processes, and Production, Experimental Developments and Applications. The Scientific Programme, selected by an International Advisory Board, included 5 Review Lectures, 11 Progress Reports, 1 Local Report and 24 Special Reports. In addition, the results of 132 contributed works were presented as poster communications and a Public Lecture on 'The wonders of the Southern Skies' was delivered by an Argentinean expert. Thus, a wide range of subjects comprising a balanced mix of topics was covered throughout the course of the conference.

Physical health in people with mental illness is often compromised. Chronic physical conditions and disease risk factors occur at higher rates than in the general population. Although substantial research exists regarding mental-physical comorbidities in middle to older-aged adults and mental illness consequential to childhood physical illness, research addressing physical health in young people/emerging adults of 16-24 years with primary mental illnesses is minimal. Health problems often track from youth to adulthood, indicating a need to better recognize and understand the overall health of young people with mental illness. This paper reports findings from an integrative review of published research investigating physical health of emerging/young adults with mental illness. A total of 18 research papers were systematically analysed. The review found that comorbid mental-physical illness/conditions were evident across a wide age span. Specific physical health problems, including pain, gastrointestinal, and respiratory disorders, were apparent in those 16 years to those in their mid-late 20s, and/or with first episode psychosis. Lifestyle risk factors for cardiometabolic disorders occurred with some frequency and originated prior to adulthood. These findings highlight the need for targeted health screening and illness prevention strategies for emerging/young adults with mental health problems and draws attention to the need for young people to be supported in their health-care behaviours. © 2012 The Authors.

Physical activity patterns of a population remain mostly assessed by the questionnaires. However, few physical activity questionnaires have been validated in Asian populations. We previously utilized a combination of different questionnaires to assess leisure time, transportation, occupational and household physical activity in the Singapore Prospective Study Program (SP2). The International Physical Activity Questionnaire (IPAQ) has been developed for a similar purpose. In this study, we compared estimates from these two questionnaires with an objective measure of physical activity in a multi-ethnic Asian population. Physical activity was measured in 152 Chinese, Malay and Asian Indian adults using an accelerometer over five consecutive days, including a weekend. Participants completed both the physical activity questionnaire in SP2 (SP2PAQ) and IPAQ long form. 43 subjects underwent a second set of measurements on average 6 months later to assess reproducibility of the questionnaires and the accelerometer measurements. Spearman correlations were used to evaluate validity and reproducibility and correlations for validity were corrected for within-person variation of accelerometer measurements. Agreement between the questionnaires and the accelerometer measurements was also evaluated using Bland Altman plots. The corrected correlation with accelerometer estimates of energy expenditure from physical activity was better for the SP2PAQ (vigorous activity: r = 0.73; moderate activity: r = 0.27) than for the IPAQ (vigorous activity: r = 0.31; moderate activity: r = 0.15). For moderate activity, the corrected correlation between SP2PAQ and the accelerometer was higher for Chinese (r = 0.38) and Malays (r = 0.57) than for Indians (r = -0.09). Both questionnaires overestimated energy expenditure from physical activity to a greater extent at higher levels of physical activity than at lower levels of physical activity. The reproducibility for moderate activity (accelerometer

The tenth meeting of the TAUP Workshop Series, TAUP 2007, was organized by the Research Center for Neutrino Science, Tohoku University. In TAUP 2007 all the various aspects of Astroparticle Physics have been covered, from Cosmology and Dark Constituents, to Gravitational Waves, to Neutrino Physics and Astrophysics, to High Energy Astrophysics, to Cosmic Rays and Gamma-Rays Astronomy. New and important scientific results were presented and debated in the plenary review talks and in a very large number of contributions in topical parallel sessions. As editors of these proceedings, we hope that this volume, which contains most of the talks and contributions presented at TAUP 2007, will provide a detailed state-of-the-art account of the various facets of Astroparticle Physics. We thank all the invited speakers, conveners, and contributors who made this possible. Full coverage of the transparencies presented at the conference can be found on the website http://www.awa.tohoku.ac.jp/taup2007.

This volume is a collection of papers associated with a series of invited lectures presented at the First Workshop on Nonequilibrium processes in Plasma Physics and studies of Environment that was held at Mt Kopaonik in August 2006. The workshop originated as a part of the FP6 COE 026328 which had the basic aim of promoting centers of excellence in Western Balkan countries, to facilitate dissemination of their results and to help them establish themselves in the broader arena of European and international science. So the best way to achieve all those goals was to prepare a workshop associated with the local conference SPIG (Symposium on Physics of Ionized Gases) where the participants could attend sessions in which the host Laboratory presented progress reports and papers and thereby gain a full perspective of our results. At the same time this allowed participants in the COE the opportunity to compare their results with the results of external speakers and to gain new perspectives and knowledge. The program of the workshop was augmented by inviting some of our colleagues who visited the COE in recent years or have an active collaboration with a participating member. In that respect this volume is not only a proceedings of the workshop but a collection of papers related to the topic of the workshop: Non-equilibrium phenomena in plasmas and in the science of our environment. The idea is to offer review articles either summarizing a broader area of published or about to be published work or to give overviews showing preliminary results of the works in progress. The refereeing of the papers consisted of two parts, first in selection of the invitees and second in checking the submitted manuscripts. The papers were refereed to the standard of the Journal. As the program of the COE covers a wide area of topics from application of plasmas in nano- electronics to monitoring and removal of pollutants in the atmosphere, so the program of the workshop covered an even broader

Many programs to increase physical activity have been evaluated in developed countries, where 'leisure time physical activity' is the most frequent domain for interventions. In developing countries, and also with reference to global obesity prevention, different kinds of interventions targeting 'total physical activity' are needed. This requires efforts across agencies and sectors, and in the domains of work, active transport, reduced sitting time, as well as leisure time physical activity promotion. In considering possible solutions, this commentary examined the use of complex systems, where integrated efforts across sectors and agencies might, in combination, contribute to increasing total physical activity. The key sets of actions required globally to increase physical activity were, in our opinion, [i] efforts to disseminate individual-level behavior change programs to reach much larger populations rather than volunteers, [ii] social marketing and mass communication campaigns to change social norms in the community and among professionals and policymakers, [iii] efforts to influence the social and physical environment to make them more conducive to physical activity, and [iv] the development and implementation of national physical activity plans and strategies, with sufficient timelines and resources to achieve measurable change.
The XVth International Conference on Calorimetry in High Energy Physics, CALOR2012, was held in Santa Fe, New Mexico from 4-8 June 2012. The series of conferences on calorimetry started in 1990 at Fermilab, and they have been the premier event for calorimeter aficionados, a trend that CALOR2012 upheld. This year, several presentations focused on the status of the major calorimeter systems, especially at the LHC. Discussions on new and developing techniques in calorimetry took a full day. Excellent updates on uses of calorimeters or about ideas that are deeply rooted in particle physics calorimetry in astrophysics and neutrino physics were followed by talks on algorithms and special triggers that rely on calorimeters. Finally, discussions of promising current developments and ongoing R&D work for future calorimeters capped the conference. The field of calorimetry is alive and well, as evidenced by the more than 100 attendees and the excellent quality of over 80 presentations. You will find the written contributions in this volume. The presentations can be found at calor2012.ttu.edu. The first day of the conference was dedicated to the LHC. In two invited talks, Guillaume Unal (CERN) and Tommaso Tabarelli de Fatis (Universita' & INFN Milano Bicocca) discussed the critical role electromagnetic calorimeters play in the hunt for the Standard Model Higgs boson in ATLAS and CMS, respectively. The enhanced sensitivity for light Higgs in the two-gamma decay channel renders electromagnetic calorimeters indispensible. Much of the higher mass region was already excluded for the SM Higgs by the time of this conference, and after less than a month, on 4 July, CERN announced the discovery of a new boson at 125 GeV, a particle that seems consistent with the Higgs particle so far. Once again, without the electromagnetic calorimeters, this would not have been possible. Professor Geoffrey West from the Santa Fe Institute gave the keynote address. His talk, 'Universal Scaling Laws

Background This paper provides an historical review of physical activity policy development in Australia for a period spanning a decade since the release of the US Surgeon General's Report on Physical Activity and Health in 1996 and including the 2004 WHO Global Strategy on Diet, Physical Activity and Health. Using our definition of 'HARDWIRED' policy criteria, this Australian review is compared with an international perspective of countries with established national physical activity policies and strategies (New Zealand, Canada, Brazil, Scotland, Switzerland, the Netherlands and Finland). Methods comprised a literature and policy review, audit of relevant web sites, document searches and surveys of international stakeholders. Results All these selected countries embraced multi-strategic policies and undertook monitoring of physical activity through national surveys. Few committed to policy of more than three years duration and none undertook systematic evaluation of national policy implementation. This Australian review highlights phases of innovation and leadership in physical activity-related policy, as well as periods of stagnation and decline; early efforts were amongst the best in the world but by the mid-point of this review (the year 2000), promising attempts towards development of a national intersectoral policy framework were thwarted by reforms in the Federal Sport and Recreation sector. Several well received reviews of evidence on good practices in physical activity and public health were produced in the period but leadership and resources were lacking to implement the policies and programs indicated. Latterly, widespread publicity and greatly increased public and political interest in chronic disease prevention, (especially in obesity and type 2 diabetes) have dominated the framework within which Australian policy deliberations have occurred. Finally, a national physical activity policy framework for the Health sector emerged, but not as a policy

The International Training Course on Physical Protection of Nuclear Facilities and Materials was intended for representatives from the developing countries who are responsible for preparing regulations and designing and assessing physical protection systems. The first part of the course consists of lectures on the objectives, organizational characteristics, and licensing and regulations requirements of a state system of physical protection. Since the participants may have little experience in nuclear energy, background information is provided on the topics of nuclear materials, radiation hazards, reactor systems, and reactor operations. Transportation of nuclear materials is addressed and emphasis is placed on regulations. Included inmore » these discussions are presentations by guest speakers from countries outside the United States of America who present their countries' threat to nuclear facilities. Effectiveness evaluation methodology is introduced to the participants by means of instructions which teach them how to use logic trees and the EASI (Estimate of Adversary Sequence Interruption) program. The following elements of a physical protection system are discussed: barriers, protective force, intrusion detection systems, communications, and entry-control systems. Total systems concepts of physical protection system design are emphasized throughout the course. Costs, manpower/technology trade-offs, and other practical considerations are discussed. Approximately one-third of the course is devoted to practical exercises during which the attendees participatein problem solving. A hypothetical nuclear facility is introduced, and the attendees participate in the conceptual design of a physical protection system for the facility.« less

Increasing physical activity and decreasing sedentary time are cornerstones in the management of type 2 diabetes (T2DM). However, there are few instruments available to measure physical activity in this population. We translated the long version of the International Physical Activity Questionnaire (IPAQ-L) into French and studied its reproducibility and validity in patients with T2DM. Reproducibility was studied by 2 telephone administrations, 8 days apart. Concurrent validity was tested against pedometry for 7 days during habitual life. One-hundred forty-three patients with T2DM were recruited (59% males; age: 60.9 ± 10.5 years; BMI: 31.2 ± 5.2 kg/m2; HbA1c: 7.4 ± 1.2%). Intraclass correlation coefficients (95% CI) for repeated administration (n = 126) were 0.74 (0.61-0.83) for total physical activity, 0.72 (0.57-0.82) for walking, and 0.65 (0.51-0.78) for sitting time. Total physical activity and walking (MET-min·week-1) correlated with daily steps (Spearman r = .24 and r = .23, respectively, P < .05). Sitting time (min·week-1) correlated negatively with daily steps in women (r = -0.33; P < .05). Our French version of the IPAQ-L appears reliable to assess habitual physical activity and sedentary time in patients with T2DM, confirming previous data in nonclinical populations.

According to the Empathizing-Systemizing theory (E-S Theory), individual differences in how people understand the physical world (systemizing) and the social world (empathizing), are two continuums in the general population with several implications, from vocational interests to skills in the social and physical domains. The underlying mechanisms of intuitive physics performance among individuals with strong systemizing and weak empathizing (systemizers) are, however, unknown. Our results affirm higher intuitive physics skills in healthy adult systemizers (N=36), and further reveal the brain mechanisms that are characteristic for those individuals in carrying out such tasks. When the participants performed intuitive physics tasks during functional magnetic resonance imaging, combined higher systemizing and lower empathizing was associated with stronger activations in parts of the default mode network (DMN, cuneus and posterior cingulate gyrus), middle occipital gyrus, and parahippocampal region. The posterior cingulate gyrus and parahippocampal gyrus were specifically associated with systemizing "brain type" even after controlling for task performance, while especially in the parietal cortex, the activation changes were simply explained by higher task performance. We therefore suggest that utilization of DMN-parahippocampal complex, suggested to play a role in internalizing and activating long-term spatial memory representations, is the factor that distinguishes systemizers from empathizers with the opposite "brain type" in intuitive physics tasks.

The documentary standards defining internationally adopted methodologies and protocols for calibrating transducers used to measure vibration are currently developed under the International Organization for Standardization (ISO) Technical Committee 108 Sub Committee 3 (Use and calibration of vibration and shock measuring instruments). Recent revisions of the documentary standards on primary methods for the calibration of accelerometers used to measure rectilinear motion have been completed. These standards can be, and have been, used as references in the technical protocols of key international and regional comparisons between National Measurement Institutes (NMIs) on the calibration of accelerometers. These key comparisons are occurring in part as a result of the creation of the Mutual Recognition Arrangement between NMIs which has appendices that document the uncertainties, and the comparisons completed in support of the uncertainties, claimed by the National Laboratories that are signatories of the MRA. The measurements for the first international and the first Interamerican System of Metrology (SIM) regional key comparisons in vibration have been completed. These intercomparisons were promulgated via the relatively new Consultative Committee for Acoustics, Ultrasound and Vibration (CCAUV) of the International Committee for Weights and Measures (CIPM) and SIM Metrology Working Group (MWG) 9, respectively.

A wide range of physical tests have been published for use in the assessment of musculoskeletal dysfunction in patients with headache. Which tests are used depends on a physiotherapist's clinical and scientific background as there is little guidance on the most clinically useful tests. To identify which physical examination tests international experts in physiotherapy consider the most clinically useful for the assessment of patients with headache. Delphi survey with pre-specified procedures based on a systematic search of the literature for physical examination tests proposed for the assessment of musculoskeletal dysfunction in patients with headache. Seventeen experts completed all three rounds of the survey. Fifteen tests were included in round one with eleven additional tests suggested by the experts. Finally eleven physical examination tests were considered clinically useful: manual joint palpation, the cranio-cervical flexion test, the cervical flexion-rotation test, active range of cervical movement, head forward position, trigger point palpation, muscle tests of the shoulder girdle, passive physiological intervertebral movements, reproduction and resolution of headache symptoms, screening of the thoracic spine, and combined movement tests. Eleven tests are suggested as a minimum standard for the physical examination of musculoskeletal dysfunctions in patients with headache. Copyright © 2016 Elsevier Ltd. All rights reserved.

To examine the relationships between physical function and gender-stereotyped traits and whether these relationships are modified by sex or social context. A total of 1995 community-dwelling older adults from the International Mobility in Aging Study (IMIAS) aged 65 to 74 years were recruited in Natal (Brazil), Manizales (Colombia), Tirana (Albania), Kingston (Ontario, Canada), and Saint-Hyacinthe (Quebec, Canada). We performed a cross-sectional analysis. Study outcomes were mobility disability, defined as having difficulty in walking 400 meters without assistance or climbing a flight of stairs without resting, and low physical performance, defined as a score < 8 on the Short Physical Performance Battery. The 12-item Bem Sex Role Inventory (BSRI) was used to classify participants into four gender roles (Masculine, Feminine, Androgynous, and Undifferentiated) using site-specific medians of femininity and masculinity as cut-off points. Poisson regression models were used to estimate prevalence rate ratios (PRR) of mobility disability and poor physical performance according to gender roles. In models adjusted for sex, marital status, education, income, and research site, when comparing to the androgynous role, we found higher prevalence of mobility disability and poor physical performance among participants endorsing the feminine role (PRR = 1.20, 95% confidence interval (CI) 1.03-1.39 and PRR = 1.37, CI 1.01-1.88, respectively) or the undifferentiated role (PRR = 1.23, 95% CI 1.07-1.42 and PRR = 1.58, CI 1.18-2.12, respectively). Participants classified as masculine did not differ from androgynous participants in prevalence rates of mobility disability or low physical performance. None of the multiplicative interactions by sex and research site were significant. Feminine and undifferentiated gender roles are independent risk factors for mobility disability and low physical performance in older adults. Longitudinal research is needed to assess the mediation pathways

The purpose of this study was to determine the level of agreement between objective physical activity (PA) (ActiHeart ® ) and subjective proxy-respondent International Physical Activity Questionnaire-short version (IPAQ-S) data in adults with intellectual disabilities (IDs). Fifty-eight participants wore ActiHeart ® monitors for seven consecutive days. Caregivers of each participant completed the IPAQ-S on behalf of the participant. Total PA, time spent in light, moderate, and vigorous activity as well as time spent being sedentary were assessed by the IPAQ-S and the ActiHeart ® . Results were compared by means of correlation analyses. The level of agreement was presented with Bland-Altman plots. Objective PA (ActiHeart ® ) was higher (225.57 ± 91.96 min/week) than IPAQ-S PA reported by care-givers (177.06 ± 309.17 min/week). Weak significant correlations were observed between the ActiHeart ® and IPAQ-S instruments for sedentary behavior (r = 0.31; p = 0.04); no significant correlations for light (r= -0.04; p = 0.8), moderate (r= -0.07; p = 0.63), or vigorous PA (r= -0.2; p = 0.18) were found. Limited agreement between objectively determine PA (ActiHeart ® ) and IPAQ-S was found. IPAQ-S is inaccurate when determining PA in persons with ID as it significantly underestimates the true levels of PA in this cohort. Implications for Rehabilitation Persons with intellectual disability (ID) report insufficient physical activity for health benefits. Physical activity is often determined by means of subjective proxy reporting. Objective physical activity measurements by means of combined heart rate and accelerometer are necessary to determine accurate levels of physical activity in persons with ID. Exercise interventions should be based on objective physical activity measurements.

In response to a world in which cancer is a growing global health challenge, there is now a greater need for US Medical Physicists and other Radiation Oncology professionals across institutions to work together and be more globally engaged in the fight against cancer. There are currently many opportunities for Medical Physicists to contribute to alleviating this pressing need, especially in helping enhance access to Medical Physics Education/training and Research Excellence across international boundaries, particularly for low and middle-income countries (LMIC), which suffer from a drastic shortage of accessible knowledge and quality training programs in radiotherapy. Many Medical Physicists aremore » not aware of the range of opportunities that even with small effort could have a high impact. Faculty at the two CAMPEP-accredited Medical Physics Programs in New England: the University of Massachusetts Lowell and Harvard Medical School have developed a growing alliance to increase Access to Medical Physics Education/training and Research Excellence (AMPERE), and facilitate greater active involvement of U.S. Medical Physicists in helping the global fight against cancer and cancer disparities. In this symposium, AMPERE Alliance members and partners from Europe and Africa will present and discuss the growing global cancer challenge, the dearth of knowledge, research, and other barriers to providing life-saving radiotherapy in LMIC, mechanisms for meeting these challenges, the different opportunities for participation by Medical Physicists, including students and residents, and how participation can be facilitated to increase AMPERE for global health. Learning Objectives: To learn about the growing global cancer challenge, areas of greatest need and limitations to accessing knowledge and quality radiotherapy training programs, especially in LMIC; To learn about the range of opportunities for Medical Physicists, including students and residents, to work together in

Hahm, T. S.
The 12th International Workshop on H-mode Physics and Transport Barriers was held at the Princeton Plasma Physics Laboratory, Princeton, New Jersey, USA between September 30 and October 2, 2009. This meeting was the continuation of a series of previous meetings which was initiated in 1987 and has been held bi-annually since then. Following the recent tradition at the last few meetings, the program was sub- divided into six sessions. At each session, an overview talk was presented, followed by two or three shorter oral presentations which supplemented the coverage of important issues. These talks were followed by discussion periods and poster sessions of contributed papers. The sessions were: Physics of Transition to/from Enhanced Confinement Regimes, Pedestal and Edge Localized Mode Dynamics, Plasma Rotation and Momentum Transport, Role of 3D Physics in Transport Barriers, Transport Barriers: Theory and Simulations and High Priority ITER Issues on Transport Barriers. The diversity of the 90 registered participants was remarkable, with 22 different nationalities. US participants were in the majority (36), followed by Japan (14), South Korea (7), and China (6). This special issue of Nuclear Fusion consists of a cluster of 18 accepted papers from submitted manuscripts based on overview talks and poster presentations. The paper selection procedure followed the guidelines of Nuclear Fusion which are essentially the same as for regular articles with an additional requirement on timeliness of submission, review and revision. One overview paper and five contributed papers report on the H-mode pedestal related results which reflect the importance of this issue concerning the successful operation of ITER. Four papers address the rotation and momentum transport which play a crucial role in transport barrier physics. The transport barrier transition condition is the main focus of other four papers. Finally, four additional papers are devoted to the behaviour and control of

The IAEA is the world's centre for cooperation in the nuclear field. It was set up as the world's ``Atoms for Peace'' organization in 1957 within the United Nations family. The Agency works with its Member States and multiple partners worldwide to promote the safe, secure and peaceful use of nuclear technologies. Three main areas of work underpin the IAEA's mission: Safety and Security, Science and Technology, and Safeguards and Verification. To carry out its mission, the Agency is authorized to encourage and assist research on, and development and practical application of, atomic energy for peaceful uses throughout the world; foster the exchange of scientific and technical information on peaceful uses of atomic energy; and encourage the exchange of training of scientists and experts in the field of peaceful uses of atomic energy. Nowadays, nuclear physics and nuclear technology are applied in a great variety of social areas, such as power production, medical diagnosis and therapies, environmental protection, security control, material tests, food processing, waste treatments, agriculture and artifacts analysis. This presentation will cover the role and practical application of physics at the IAEA, and, in particular, focus on the role physics has, and will play, in nuclear security.

Background The Physical Activity and Sedentary Behaviour Assessment Questionnaire (PASBAQ), used within the Health Survey for England (HSE) at 5-yearly intervals, is not included annually due to funding and interview-length constraints. Policy-makers and data-users are keen to consider shorter instruments such as the Short-form International Physical Activity Questionnaire (IPAQ) for the annual survey. Both questionnaires were administered in HSE 2012, enabling comparative assessment in a random sample of 1252 adults. Methods Relative agreement using prevalence-adjusted bias-adjusted Kappa (PABAK) statistics was estimated for: sufficient aerobic activity (moderate-to-vigorous physical activity [MVPA] ≥150minutes/week); inactivity (MVPA<30minutes/week); and excessive sitting (≥540minutes/weekday). Cross-sectional associations with health outcomes were compared across tertiles of MVPA and tertiles of sitting time using logistic regression with tests for linear trend. Results Compared with PASBAQ data, IPAQ-assessed estimates of sufficient aerobic activity and inactivity were higher and lower, respectively; estimates of excessive sitting were higher. Demographic patterns in prevalence were similar. Agreement using PABAK statistics was fair-to-moderate for sufficient aerobic activity (0.32–0.49), moderate-to-substantial for inactivity (0.42–0.74), and moderate-to-substantial for excessive sitting (0.49–0.75). As with the PASBAQ, IPAQ-assessed MVPA and sitting each showed graded associations with mental well-being (women: P for trend = 0.003 and 0.004, respectively) and obesity (women: P for trend = 0.007 and 0.014, respectively). Conclusions Capturing habitual physical activity and sedentary behaviour through brief questionnaires is complex. Differences in prevalence estimates can reflect differences in questionnaire structure and content rather than differences in reported behaviour. Treating all IPAQ-assessed walking as moderate-intensity contributed to the

The "International Workshop on Theoretical Plasma Physics: Modern Plasma Science was held at the Abdus Salam International Centre for Theoretical Physics (Abdus Salam ICTP), Trieste, Italy during the period 5 16 July 2004. The workshop was organized by P K Shukla, R Bingham, S M Mahajan, J T Mendonça, L Stenflo, and others. The workshop enters into a series of previous biennial activities that we have held at the Abdus Salam ICTP since 1989. The scientific program of the workshop was split into two parts. In the first week, most of the lectures dealt with problems concerning astrophysical plasmas, while in the second week, diversity was introduced in order to address the important role of plasma physics in modern areas of science and technology. Here, attention was focused on cross-disciplinary topics including Schrödinger-like models, which are common in plasma physics, nonlinear optics, quantum engineering (Bose-Einstein condensates), and nonlinear fluid mechanics, as well as emerging topics in fundamental theoretical and computational plasma physics, space and dusty plasma physics, laser-plasma interactions, etc. The workshop was attended by approximately hundred-twenty participants from the developing countries, Europe, USA, and Japan. A large number of participants were young researchers from both the developing and industrial countries, as the directors of the workshop tried to keep a good balance in inviting senior and younger generations of theoretical, computational and experimental plasma physicists to our Trieste activities. In the first week, there were extensive discussions on the physics of electromagnetic wave emissions from pulsar magnetospheres, relativistic magnetohydrodynamics of astrophysical objects, different scale sizes turbulence and structures in astrophysics. The scientific program of the second week included five review talks (60 minutes) and about thirty invited topical lectures (30 minutes). In addition, during the two weeks, there

Background The International Physical Activity Questionnaire (IPAQ-SF) has been validated and recommended as an efficient method to assess physical activity, but its validity has not been investigated in different population subgroups. We examined variations in IPAQ validity in the Hong Kong Chinese population by six factors: sex, age, job status, educational level, body mass index (BMI), and visceral fat level (VFL). Methods A total of 1,270 adults (aged 42.9 ± SD 14.4 years, 46.1% male) completed the Chinese version of IPAQ (IPAQ-C) and wore an accelerometer (ActiGraph) for four days afterwards. The IPAQ-C and the ActiGraph were compared in terms of estimated Metabolic Equivalent Task minutes per week (MET-min/wk), minutes spent in activity of moderate or vigorous intensity (MVPA), and agreement in the classification of physical activity. Results The overall Spearman correlation (ρ) of between the IPAQ-C and ActiGraph was low (0.11 ± 0.03; range in subgroups 0.06-0.24) and was the highest among high VFL participants (0.24 ± 0.05). Difference between self-reported and ActiGraph-derived MET-min/wk (overall 2966 ± 140) was the smallest among participants with tertiary education (1804 ± 208). When physical activity was categorized into over or under 150 min/wk, overall agreement between self-report and accelerometer was 81.3% (± 1.1%; subgroup range: 77.2%-91.4%); agreement was the highest among those who were employed full-time in physically demanding jobs (91.4% ± 2.7%). Conclusions Sex, age, job status, educational level, and obesity were found to influence the criterion validity of IPAQ-C, yet none of the subgroups showed good validity (ρ = 0.06 to 0.24). IPAQ-SF validity is questionable in our Chinese population. PMID:21801461

Background Clinical guidelines are considered important instruments to improve quality in health care. Since 1998 the Royal Dutch Society for Physical Therapy (KNGF) produced evidence-based clinical guidelines, based on a standardized program. New developments in the field of guideline research raised the need to evaluate and update the KNGF guideline program. Purpose of this study is to compare different guideline development programs and review the KNGF guideline program for physical therapy in the Netherlands, in order to update the program. Method Six international guideline development programs were selected, and the 23 criteria of the AGREE Instrument were used to evaluate the guideline programs. Information about the programs was retrieved from published handbooks of the organizations. Also, the Dutch program for guideline development in physical therapy was evaluated using the AGREE criteria. Further comparison the six guideline programs was carried out using the following elements of the guideline development processes: Structure and organization; Preparation and initiation; Development; Validation; Dissemination and implementation; Evaluation and update. Results Compliance with the AGREE criteria of the guideline programs was high. Four programs addressed 22 AGREE criteria, and two programs addressed 20 AGREE criteria. The previous Dutch program for guideline development in physical therapy lacked in compliance with the AGREE criteria, meeting only 13 criteria. Further comparison showed that all guideline programs perform systematic literature searches to identify the available evidence. Recommendations are formulated and graded, based on evidence and other relevant factors. It is not clear how decisions in the development process are made. In particular, the process of translating evidence into practice recommendations can be improved.

Abused children's internal working models (IWM) of relationships are known to relate to their socioemotional adjustment, but mechanisms through which negative representations increase vulnerability to maladjustment have not been explored. We sought to expand the understanding of individual differences in IWM of abused children and investigate the mediating role of self-regulation in links between IWM and adjustment. Cluster analysis was used to subgroup 74 physically abused children based on their IWM. Internal working models were identified by children's representations, as measured by a narrative story stem task. Self-regulation was assessed by teacher report and a behavioral task, and adjustment was measured by teacher report. Cluster analyses indicated two subgroups of abused children with distinct patterns of IWMs. Cluster membership predicted internalizing and externalizing problems. Associations between cluster membership and adjustment were mediated by children's regulation, as measured by teacher reports of many aspects of regulation. There was no support for mediation when regulation was measured by a behavioral task that tapped more narrow facets of regulation. Abused children exhibit clinically relevant individual differences in their IWMs; these models are linked to adjustment in the school setting, possibly through children's self-regulation. © 2013 The Authors.

A series of experiments have been carried out in 2008 at JT-60U and JET to find common characteristics and explain differences between internal transport barriers (ITBs). The identity experiments succeeded in matching the profiles of most dimensionless parameters at the time ITBs were triggered. Thereafter the q-profile development deviated due to differences in non-inductive current density profile, affecting the ITB. Furthermore, the ITBs in JET were more strongly influenced by the H-mode pedestal or edge localized modes. It was found to be difficult to match the plasma rotation characteristics in both devices. However, the wide range of Mach numbers obtained in these experiments shows that the rotation has little effect on the triggering of ITBs in plasmas with reversed magnetic shear. On the other hand the toroidal rotation and more specifically the rotational shear had an impact on the subsequent growth and allowed the formation of strong ITBs.
Fluids are present everywhere in everyday life. They are also present as fuel, in support systems or as consumable in rockets and onboard of satellites and space stations. Everyone experiences every day that fluids are very sensitive to gravity: on Earth liquids flow downwards and gases mostly rise. Nowadays much of the interest of the scientific community is on studying the phenomena at microscales in so-called microfluidic systems. However, at smaller scales the experimental investigation of convective flows becomes increasingly difficult as the control parameter Ra scales with g L (3) (g; acceleration level, L: length scale). A unique alternative to the difficulty of investigating systems with small length scale on the ground is to reduce the gravity level g. In systems with interfaces, buoyancy forces are proportional to the volume of the liquid, while capillary forces act solely on the liquid surface. The importance of buoyancy diminishes either at very small scales or with reducing the acceleration level. Under the weightless conditions of space where buoyancy is virtually eliminated, other mechanisms such as capillary forces, diffusion, vibration, shear forces, electrostatic and electromagnetic forces are dominating in the fluid behaviour. This is why research in space represents a powerful tool for scientific research in this field. Understanding how fluids work really matters and so does measuring their properties accurately. Presently, a number of scientific laboratories, as usual goes with multi-user instruments, are involved in fluid research on the ISS. The programme of fluid physics experiments on-board deals with capillary flows, diffusion, dynamics in complex fluids (foams, emulsions and granular matter), heat transfer processes with phase change, physics and physico-chemistry near or beyond the critical point and it also extends to combustion physics. The top-level objectives of fluid research in space are as follows: (i) to investigate fluid

Objectives To examine the relationships between physical function and gender-stereotyped traits and whether these relationships are modified by sex or social context. Methods A total of 1995 community-dwelling older adults from the International Mobility in Aging Study (IMIAS) aged 65 to 74 years were recruited in Natal (Brazil), Manizales (Colombia), Tirana (Albania), Kingston (Ontario, Canada), and Saint-Hyacinthe (Quebec, Canada). We performed a cross-sectional analysis. Study outcomes were mobility disability, defined as having difficulty in walking 400 meters without assistance or climbing a flight of stairs without resting, and low physical performance, defined as a score < 8 on the Short Physical Performance Battery. The 12-item Bem Sex Role Inventory (BSRI) was used to classify participants into four gender roles (Masculine, Feminine, Androgynous, and Undifferentiated) using site-specific medians of femininity and masculinity as cut-off points. Poisson regression models were used to estimate prevalence rate ratios (PRR) of mobility disability and poor physical performance according to gender roles. Results In models adjusted for sex, marital status, education, income, and research site, when comparing to the androgynous role, we found higher prevalence of mobility disability and poor physical performance among participants endorsing the feminine role (PRR = 1.20, 95% confidence interval (CI) 1.03–1.39 and PRR = 1.37, CI 1.01–1.88, respectively) or the undifferentiated role (PRR = 1.23, 95% CI 1.07–1.42 and PRR = 1.58, CI 1.18–2.12, respectively). Participants classified as masculine did not differ from androgynous participants in prevalence rates of mobility disability or low physical performance. None of the multiplicative interactions by sex and research site were significant. Conclusion Feminine and undifferentiated gender roles are independent risk factors for mobility disability and low physical performance in older adults. Longitudinal

Accurate assessment of physical activity is important in determining the risk for chronic diseases such as cardiovascular disease, stroke, type 2 diabetes, cancer and obesity. The absence of culturally relevant measures in indigenous languages could pose challenges to epidemiological studies on physical activity in developing countries. The purpose of this study was to translate and cross-culturally adapt the Short International Physical Activity Questionnaire (IPAQ-SF) to the Hausa language, and to evaluate the validity and reliability of the Hausa version of IPAQ-SF in Nigeria. The English IPAQ-SF was translated into the Hausa language, synthesized, back translated, and subsequently subjected to expert committee review and pre-testing. The final product (Hausa IPAQ-SF) was tested in a cross-sectional study for concurrent (correlation with the English version) and construct validity, and test-retest reliability in a sample of 102 apparently healthy adults. The Hausa IPAQ-SF has good concurrent validity with Spearman correlation coefficients (ρ) ranging from 0.78 for vigorous activity (Min Week-1) to 0.92 for total physical activity (Metabolic Equivalent of Task [MET]-Min Week-1), but poor construct validity, with cardiorespiratory fitness (ρ = 0.21, p = 0.01) and body mass index (ρ = 0.22, p = 0.04) significantly correlated with only moderate activity and sitting time (Min Week-1), respectively. Reliability was good for vigorous (ICC = 0.73, 95% C.I = 0.55-0.84) and total physical activity (ICC = 0.61, 95% C.I = 0.47-0.72), but fair for moderate activity (ICC = 0.33, 95% C.I = 0.12-0.51), and few meaningful differences were found in the gender and socioeconomic status specific analyses. The Hausa IPAQ-SF has acceptable concurrent validity and test-retest reliability for vigorous-intensity activity, walking, sitting and total physical activity, but demonstrated only fair construct validity for moderate and sitting activities. The Hausa IPAQ-SF can be used for
The 13th International Workshop on H-mode Physics and Transport Barriers, held in Lady Margaret Hall College in Oxford in October 2011 continues the tradition of bi-annual international meetings dedicated to the study of transport barriers in fusion plasmas. The first meeting of this series took place in S Diego (CA, US) in 1987, and since then scientists in the fusion community studying the formation and effects of transport barriers in plasmas have been meeting at this small workshop to discuss progress, new experimental evidence and related theoretical studies. The first workshops were strongly focussed on the characterization and understanding of the H-mode plasma, discovered in ASDEX in 1982. Tokamaks throughout the entire world were able to reproduce the H-mode transition in the following few years and since then the H-mode has been recognised as a pervasive physics feature of toroidally confined plasmas. Increased physics understanding of the H-mode transition and of the properties of H-mode plasmas, together with extensive development of diagnostic capabilities for the plasma edge, led to the development of edge transport barrier studies and theory. The H-mode Workshop reflected this extension in interest, with more and more contributions discussing the phenomenology of edge transport barriers and instabilities (ELMs), L-H transition and edge transport barrier formation theory. In the last 15 years, in response to the development of fusion plasma studies, the scientific scope of the workshop has been broadened to include experimental and theoretical studies of both edge and internal transport barriers, including formation and sustainment of transport barriers for different transport channels (energy, particle and momentum). The 13th H-mode Workshop was organized around six leading topics, and, as customary for this workshop, a lead speaker was selected for each topic to present to the audience the state-of-the-art, new understanding and open issues, as well

Physical samples such as minerals, soil, rocks, water, air and plants are important observational units for understanding the complexity of our environment and its resources. They are usually collected and curated by different entities, e.g., individual researchers, laboratories, state agencies, or museums. Persistent identifiers may facilitate access to physical samples that are scattered across various repositories. They are essential to locate samples unambiguously and to share their associated metadata and data systematically across the Web. The International Geo Sample Number (IGSN) is a persistent, globally unique label for identifying physical samples. The IGSNs of physical samples are registered by end-users (e.g., individual researchers, data centers and projects) through allocating agents. Allocating agents are the institutions acting on behalf of the implementing organization (IGSN e.V.). The Commonwealth Scientific and Industrial Research Organisation CSIRO) is one of the allocating agents in Australia. To implement IGSN in our organisation, we developed a RESTful service and a metadata model. The web service enables a client to register sub-namespaces and multiple samples, and retrieve samples' metadata programmatically. The metadata model provides a framework in which different types of samples may be represented. It is generic and extensible, therefore it may be applied in the context of multi-disciplinary projects. The metadata model has been implemented as an XML schema and a PostgreSQL database. The schema is used to handle sample registrations requests and to disseminate their metadata, whereas the relational database is used to preserve the metadata records. The metadata schema leverages existing controlled vocabularies to minimize the scope for error and incorporates some simplifications to reduce complexity of the schema implementation. The solutions developed have been applied and tested in the context of two sample repositories in CSIRO, the

Physical fitness training of military recruits is an enduring focus of armies. This is important for safe and effective performance of general tasks that anyone may have to perform in a military setting as well as preparation for more specialized training in specific job specialties. Decades of studies on occupationally specific physical requirements have characterized the dual aerobic and strength demands of typical military tasks; however, scientifically founded strategies to prepare recruits with a good mix of these 2 physiologically opposing capabilities have not been well established. High levels of aerobic training can compromise resistance training gains and increase injury rates. Resistance training requires a greater commitment of time and resources as well as a greater understanding of the science to produce true strength gains that may be beneficial to military performance. These are critical issues for modern armies with increased demands for well-prepared soldiers and fewer injury losses. The actual physical requirements tied to metrics of success in military jobs are also under renewed examination as women are increasingly integrated into military jobs previously performed only by men. At the third International Congress on Soldiers' Physical Performance, a roundtable of 10 physiologists with military expertise presented comparative perspectives on aerobic and strength training. These topics included the physiological basis of training benefits, how to train effectively, how to measure training effectiveness, considerations for the integration of women, and the big perspective. Key discussion points centered on (a) the significance of findings from research on integrated training, (b) strategies for effective strength development, and (c) injury reduction in training as well as the benefits of improved fitness to injury reduction across the force.

To implement appropriate programs for promoting physical activity (PA) in people who are Deaf, it is important to have valid instruments for assessing PA in this population. The main purpose of this study was to examine the criterion validity of the short form of the International Physical Activity Questionnaire (IPAQ-S) in Deaf adults. This study included 44 adults (18-65 years) of both genders (63.6% were females) who met the inclusion criteria. Objective measures of PA were collected using accelerometers, which were worn by each participant during one week. After using the accelerometer, the IPAQ-S was applied to assess participants' physical activity during the last 7 days. There was no significant correlation between the average time spent in moderate to vigorous physical activity (MVPA) as measured by the accelerometer (40.1 ± 24.5 min/day) and by the IPAQ-S (41.3 ± 57.5 min/day). The IPAQ-S significantly underestimated the time spent in sedentary behavior (7.6 ± 2.7 h/day vs. 10.1 ± 1.6 h/day). Sedentary behavior and MVPA as measured by the accelerometer and the IPAQ-S showed limited agreement. Our results show some limitations on the use of IPAQ-S for quantifying PA among adults who are Deaf. The IPAQ-S tends to overestimate the MVPA and to underestimate sedentary behavior in adults who are Deaf. Copyright Â© 2016 Elsevier Inc. All rights reserved.
The 11th International Seminar on Nuclear Physics was held in Ischia from May 12 to May 16, 2014. This Seminar was dedicated to Aldo Covello, who has been the promoter of this series of meetings, which started in Sorrento in 1986 and continued with meetings held every two or three years in the Naples area. Aldo's idea was to offer to a group of researchers, actively working in selected fields of Nuclear Physics, the opportunity to confront their points of view in a lively and informal way. The choice for the period of the year, Spring, as well as the sites chosen reflected this intent. The first meeting was of a purely theoretical nature, but it was immediately clear that the scope of these conferences needed to be enlarged calling into play the experimental community. Then, starting from the second meeting, all the following ones have been characterized by fruitful discussion between theoretical and experimental researchers on current achievements and future developments of nuclear structure. This may be read, in fact, as one of the motivating factors for Aldo's election as Fellow of the American Physical Society in 2008 "... for his outstanding contributions to the international nuclear physics community by providing, for over two decades, a venue for theorists and experimentalists to share their latest ideas." The present meeting, organized by Aldo's former students and with the benefit of his suggestions, has maintained this tradition. The title "Shell model and nuclear structure: achievements of the past two decades" recalls that of the 2nd International Spring Seminar "Shell Model and Nuclear Structure: where do we stand?". The main aim of this 11th Seminar was, in fact, to discuss the changes of the past two decades on our view of nuclei in terms of shell structure as well as the perspectives of the shell model, which has been one of the key points in Aldo's research. This point is well accounted by the Opening Speech of Igal Talmi, one of the fathers of the
The third Workshop on Historical Seismograms, held in Hamburg on August 18-19, 1983, in conjunction with the meeting of the International Union of Geodesy and Geophysics in Hamburg, Federal Republic of Germany, was specifically organized to discuss the status of historical seismic data for Latin America and Europe. Since it is unlikely that an additional workshop will be held on this subject, reports for other regions were included as well.In the first session, H. Meyers described the purpose of the workshop and gave some history of the previous activities of the IASPEI/Unesco Working Group on Historical Seismograms. E.R. Engdahl noted that thus far more than 500,000 seismograms have been filmed as part of the Historical Microfilming Project and emphasized the importance of the activities to be covered during the workshop. M. Hashizume, representing Unesco, described the importance of historical seismic data and the Unesco interests in having these data available for the analysis of seismic risks, particularly in areas where the recurrence rate of significant earthquakes is very low and for regions where much data do not exist. He mentioned that both these conditions occur frequently in developing nations.
The third biannual conference on 'Discovery Physics at the LHC' was held on December 1-6 2014 at the Kruger Gate Hotel in South Africa. Over 100 participants attended from Austria, Australia, Belgium, Brazil, Canada, China, the Czech Republic, France, Germany, Italy, the Netherlands, Norway, Poland, South Africa, Switzerland, the UK and the USA. The latest results from the Large Hadron Collider as well the latest theoretical insights were presented. With the majestic Kruger National Park in the background this led to a very stimulating conference with many exchanges taking place. The proceedings reflect the high level of the conference. The financial contributions from the SA-CERN programme, the UCT-CERN Research Centre, the University of Johannesburg, the University of the Witwatersrand and iThemba L.A.B.S. are gratefully acknowledged.

The 2013 Joint IMEKO (International Measurement Confederation) TC1-C7-TC13 was organised by the University of Genova - DIME/MEC, Measurement Laboratory, Italy, on 4-6 September 2013. The work of this symposium is reported in this volume. The scope of the symposium includes the main topics covered by the above Technical Committees: TC1 Education and Training in Measurement and Instrumentation TC7 Measurement Science TC13 Measurements in Biology and Medicine This is in keeping with the tradition set by the previous events of this well established series. There has been a special focus on measurement across physical and behavioural sciences, with the aim of highlighting the interdisciplinary character of measurement science and of promoting constructive interactions with scientists in other disciplines. The discussion was introduced by keynote lectures on measurement challenges in psychophysics, psychometrics and quantum physics. The symposium was attended by experts working in these areas from 18 countries, including USA, Australia and Japan, and provided a useful forum for them to share and exchange their work and ideas. In total over sixty papers are included in the volume, organised according to the presentation sessions. Each paper was independently peer-reviewed by two reviewers from a distinguished international panel. The Symposium was held in Genova, which was the European Capital of Culture in 2004, and took place in Palazzo Ducale, an important historical building whose construction started in the 13th century, and that has been the house of the Duke of Genova from the 14th century. Genova, whose name comes from the Latin word 'Janua' (meaning 'door', as January is the door month of the year), has been regarded over the centuries as a door connecting Europe with the different countries and cultures of the Mediterranean basin and thus was an appropriate site for an international symposium involving different and new scientific visions and approaches to

Clinical practice guidelines on the management of neck pain make recommendations to help practitioners optimize patient care. By examining the practice patterns of practitioners, adherence to CPGs or lack thereof, is demonstrated. Understanding utilization of various treatments by practitioners and comparing these patterns to that of recommended guidelines is important to identify gaps for knowledge translation and improve treatment regimens. To describe the utilization of interventions in patients with neck pain by clinicians. A cross-sectional international survey was conducted from February 2012 to March 2013 to determine physical medicine, complementary and alternative medicine utilization amongst 360 clinicians treating patients with neck pain. The survey was international (19 countries) with Canada having the largest response (38%). Results were analyzed by usage amongst physical therapists (38%) and chiropractors (31%) as they were the predominant respondents. Within these professions, respondents were male (41-66%) working in private practice (69-95%). Exercise and manual therapies were consistently (98-99%) used by both professions but tests of subgroup differences determined that physical therapists used exercise, orthoses and 'other' interventions more, while chiropractors used phototherapeutics more. However, phototherapeutics (65%), Orthoses/supportive devices (57%), mechanical traction (55%) and sonic therapies (54%) were not used by the majority of respondents. Thermal applications (73%) and acupuncture (46%) were the modalities used most commonly. Analysis of differences across the subtypes of neck pain indicated that respondents utilize treatments more often for chronic neck pain and whiplash conditions, followed by radiculopathy, acute neck pain and whiplash conditions, and facet joint dysfunction by diagnostic block. The higher rates of usage of some interventions were consistent with supporting evidence (e.g. manual therapy). However, there was

The confirmation by the NASA MESSENGER spacecraft that Mercury has an internal magnetic field that is well described by a dipole nearly aligned with the spin axis strongly suggests that the planet may have an outer core of molten metal (S. Solomon, MESSENGER news release of 30 January 2008). The existence of an internal layer of liquid has also been invoked to explain radar measurements of the large amplitude of the longitudinal libration of Mercury relative to the value expected for a wholly solid planet (J.L. Margot et al 2007 Science 316 710). The existence of molten metal in the planet`s interior is surprising since previous numerical models for the thermal evolution of the planet, calculated on the basis of the heat released by the decay of the radioactive isotopes of U and Th, indicated that the present temperature at the edge of the metal core is only ~ 1200 K (cf. Siegfried & Solomon 1974 Icarus 23 192) . This value is well below the melting temperature Tm = 2030 K of Fe-Ni alloy at the core/mantle boundary (CMB) pressure of ~ 70 kbar. Those earlier thermal calculations were, however, based on low abundances of U and Th found in lunar samples. Prentice (2008 LPSC 2008 abs. # 1945.pdf - see URL below) has put forward a new model for the bulk chemical composition of Mercury. It is based on the idea that this planet condensed from a gas ring that was cast off by the protosolar cloud close to the planet`s present orbit. The temperature of the gas ring Tn at the moment of detachment from the cloud is 1628 K and the pressure on the mean orbit of the ring is 0.168 bar. Because Tn is so high, the condensate contains a much reduced proportion of magnesium silicates relative to metals. This is because metals have a much lower vapour pressure than those silicates. The condensate consists mostly of Fe-Ni-Cr-Co-V (mass fraction 0.671), gehlenite (0.190) and Mg-silicates (0.081). What is really important in the gas ring model of solar system origin, however, is that the

The Earth's land surface, including its biomass, is an integral part of the Earth's weather and climate system. Land surface heterogeneity, such as the type and amount of vegetative covering., has a profound effect on local weather variability and therefore on regional variations of the global climate. Surface conditions affect local weather and climate through a number of mechanisms. First, they determine the re-distribution of the net radiative energy received at the surface, through the atmosphere, from the sun. A certain fraction of this energy increases the surface ground temperature, another warms the near-surface atmosphere, and the rest evaporates surface water, which in turn creates clouds and causes precipitation. Second, they determine how much rainfall and snowmelt can be stored in the soil and how much instead runs off into waterways. Finally, surface conditions influence the near-surface concentration and distribution of greenhouse gases such as carbon dioxide. The processes through which these mechanisms interact with the atmosphere can be modeled mathematically, to within some degree of uncertainty, on the basis of underlying physical principles. Such a land surface model provides predictive capability for surface variables including ground temperature, surface humidity, and soil moisture and temperature. This information is important for agriculture and industry, as well as for addressing fundamental scientific questions concerning global and local climate change. In this study we apply a methodology known as tangent linear modeling to help us understand more deeply, the behavior of the Mosaic land surface model, a model that has been developed over the past several years at NASA/GSFC. This methodology allows us to examine, directly and quantitatively, the dependence of prediction errors in land surface variables upon different vegetation conditions. The work also highlights the importance of accurate soil moisture information. Although surface

Although proof-of-concept for mobile health (mHealth) life-style programs targeting physical inactivity and overweight/obesity has been established in randomized trials, the feasibility and effect of a globally distributed, large-scale, mass-participation mHealth implementation has not been investigated. The purpose of this study was to determine the effect of Stepathlon, an international, low-cost, mass-participation mHealth intervention, on physical activity, sitting, and weight. We prospectively collected cohort data from participants completing Stepathlon, an annual 100-day global event in 2012, 2013, and 2014. Participants were organized in worksite-based teams, issued pedometers, and encouraged to increase daily steps and physical activity as part of the team-based race. The program was conducted via an interactive multiplatform application available on mobile devices and the Internet. Analysis was performed according to a pre-specified plan. A total of 69,219 subjects participated (481 employers, 1,481 cities, 64 countries, all populated continents, age 36 ± 9 years, 23.9% female, 8.0% high-income countries, and 92.0% lower-middle income countries). After Stepathlon completion, participants recorded improved step count (+3,519 steps/day; 95% confidence interval [CI]: 3,484 to 3,553 steps/day; p < 0.0001), exercise days (+0.89 days; 95% CI: 0.87 to 0.92 days; p < 0.0001), sitting duration (-0.74 h; 95% CI: -0.78 to -0.71 h; p < 0.0001) and weight (-1.45 kg; 95% CI: -1.53 to -1.38 kg; p < 0.0001). Improvements occurred in women and men, in all geographic regions, and in both high and lower-middle income countries, and the results were reproduced in 2012, 2013, and 2014 cohorts. Predictors of weight loss included step increase, sitting duration decrease, and increase in exercise days (all p < 0.0001). Distributed mHealth implementation of a low-cost life-style intervention is associated with short-term, reproducible, large-scale improvements in
The biannual Workshop on Physical Chemistry of Wet Etching of Semiconductors (PCWES) was held in Saarbrücken, Germany in June 2006 for the fifth time in its history. The event was initiated in 1998 by Miko Elwenspoek from Twente University. It is a dedicated workshop with a typical attendance of about 30 scientists with multidisciplinary backgrounds from all parts of the world working in the field. Starting off in Holten in The Netherlands in 1998, subsequent workshops have been held at Toulouse, France in 2000, Nara, Japan in 2002, and Montreal, Canada in 2004. The initial focus was upon anisotropic etching of silicon in alkaline solutions, including surface topology, modelling aspects and applications. This process has found a wide range of applications in microsystems technology (MST), i.e. in the fabrication of microelectromechanical systems (MEMS). Most prominently, it provides the technological basis for bulk micromachining. More recently, other semiconductors such as germanium, III-V compounds and, particularly, wide-bandgap materials have started to enter the field. Furthermore, electrochemical aspects have gained in importance and the formation of porous silicon has also become a considerable part of the programme. From the very beginning up to the present time there was and is a strong focus on illumination of the underlying mechanism of crystallographic anisotropy, as well as on the understanding of electrochemical and dopant-induced etch stop phenomena. The fifth workshop, presented in Saarbrücken, included a total of twenty four contributions, six of which were as posters. Five of these are included in this partial special issue of Journal of Micromechanics and Microengineering as full length papers after having undergone the standard review process. The selection of contributions starts with the first invited paper given by M Gosalvez et al, resulting from a collaboration between Nagoya University, Japan and Helsinki University of Technology

The purpose of this multinational and cross-sectional study was to investigate whether nighttime sleep duration was associated with physical activity (PA) and sedentary time (SED) the following day, whether daytime PA/SED were associated with sleep duration the subsequent night, and whether the associations were modified by sex and study sites. Data from 5779 children aged 9-11years were analyzed. A waist-worn Actigraph GT3X+ accelerometer was used to assess children's 24-h movement behaviours for 7days, i.e. sleep duration, total SED, light-intensity physical activity (LPA), and moderate- to vigorous-intensity physical activity (MVPA). Multilevel linear regression models were used to account for the repeated measures nested within participants (there were up to 7 sleep→PA/SED and PA/SED→sleep pairings per participant) and schools, and adjusted for covariates. To facilitate interpretation, all sleep and PA/SED variables were standardized. Results showed that the relationship between sleep and PA/SED is bi-directional in this international sample of children. Specifically, for each one standard deviation (SD) unit increase in sleep duration, SED the following day decreased by 0.04 SD units, while LPA and MVPA increased by 0.04 and 0.02 SD units, respectively. Sleep duration decreased by 0.02 SD units and increased by 0.04 SD units for each one SD unit increase in SED and MVPA, respectively. Sleep duration was not affected by changes in LPA. These associations differed across sex and study sites in both directions. However, since the observed effect sizes are subtle, public health initiatives should consider the clinical and practical relevance of these findings. Copyright © 2017 Elsevier Inc.

Given the travel that punctuates junior tennis development, an understanding of the changes in fitness owing to touring and the association between training loads (TLs) and fitness on return is vital. The authors investigated physical-capacity changes from pretour to posttour, determining if those changes were related to the TL of athletes on tour. Thirty junior athletes completed fitness testing before and after 4-wk tours. Testing included double-leg countermovement jump (CMJ), dominant single-leg and nondominant single-leg CMJ, speed (5, 10, 20 m), modified 5-0-5 agility (left and right), 10 × 20-m repeated-sprint ability (RSA), and multistage fitness tests. Repeated-measures ANOVAs determined physical-capacity change, with effect-size analysis establishing the magnitude of change. To avoid regression toward the mean, a 1/3-split technique was implemented for comparative analysis (high to low TLs). Moderate effects (d=0.50-0.70) for reductions of up to 3.6% in 5-, 10-, and 20-m speeds were observed. However, all remaining changes were only of trivial to small magnitude (d<0.40). Closer analysis of the interaction between TL and physical capacities (1/3-split) revealed that subjects who completed the greatest amount of total and tennis TL returned with a greater decline in speed and aerobic capacities (d>0.80). Furthermore, it was observed that match load dictates on- and off-court TL, with an increase in matches won understandably stunting exposure to off-court TL. Specific training should be prescribed on tour to maintain speed characteristics over a 4-wk international tour. On-tour training schedules should be carefully monitored to maximize specific TL exposure after losses on tour.

Studies among youth suggest that physical inactivity, sedentary behaviors, and poor diet quality are associated with poor mental health. Few population-based studies have investigated these relationships longitudinally. We examined the association between physical activity, sedentary behaviors, and diet quality in childhood and the incidence of internalizing and externalizing disorders throughout adolescence. We linked health behavior survey data from 2003 among 10- to 11-year-old children across Nova Scotia, Canada, with administrative health care data from 2003 to 2011. Students' diet quality was assessed using the Harvard Food Frequency Questionnaire. Physical activity and sedentary behaviors were self-reported, and internalizing and externalizing disorders were diagnosed by a physician. We applied Cox regression to examine the associations of the health behaviors with the incidence of internalizing and externalizing disorders between 2003 and 2011. Of the 4861 participating students, 23.7% and 9.4% had a diagnosis of internalizing and externalizing disorders, respectively. The incidences of internalizing and externalizing disorders were higher among students who were less physically active and spent more time using computers and video games. These findings suggest that promoting an active lifestyle in childhood may contribute to the prevention of both internalizing and externalizing disorders during adolescence.

countries only one MP responsible for each Center is currently mandated. Currently there is a large disparity among MP training programs and there is significant debate about the standards of MP graduate education in many LA countries. There are no commonly recognized academic programs, not enough clinical training sites and clinical training is not typically considered as part of the MP work. Economic pressures and high workloads also impede the creation of more training centers. The increasing need of qualified MPs require establishing a coordinated system of national Education & Training Centers (ETC), to meet the international standards of education and training in Medical Physics. This shortfall calls for support of organizations such as the IOMP, AAPM, ALFIM, IAEA, etc. Examples from various LA countries, as well as some proposed solutions, will be presented. In particular, we will discuss the resources that the AAPM and its members can offer to support regional programs. The ‘Medical Imaging’ physicist in the emerging world: Challenges and opportunities - Caridad Borrás (WGNIMP Chair) While the role of radiation therapy physicists in the emerging world is reasonably well established, the role of medical imaging physicists is not. The only perceived needs in radiology departments are equipment quality control and radiation protection, tasks that can be done by a technologist or a service engineer. To change the situation, the International Basic Safety Standard, which is adopted/adapted world-wide as national radiation protection regulations, states: “For diagnostic radiological procedures and image guided interventional procedures, the requirements of these Standards for medical imaging, calibration, dosimetry and quality assurance, including the acceptance and commissioning of medical radiological equipment, are fulfilled by or under the oversight of, or with the documented advice of a medical physicist, whose degree of involvement is determined by the
The purpose of this review was to determine the degree to which physical activity interventions for Latin American populations reported on internal and external validity factors using the RE-AIM framework (reach & representativeness, effectiveness, adoption, implementation, maintenance). We systematically identified English (PubMed; EbscoHost) and Spanish (SCIELO; Biblioteca Virtual en Salud) language studies published between 2001 and 2012 that tested physical activity, exercise, or fitness promotion interventions in Latin American populations. Cross-sectional/descriptive studies, conducted in Brazil or Spain, published in Portuguese, not including a physical activity/fitness/exercise outcome, and with one time point assessment were excluded. We reviewed 192 abstracts and identified 46 studies that met the eligibility criteria (34 in English, 12 in Spanish). A validated 21-item RE-AIM abstraction tool was used to determine the quality of reporting across studies (0-7 = low, 8-14 = moderate, and 15-21 = high). The number of indicators reported ranged from 3–14 (mean = 8.1 ± 2.6), with the majority of studies falling in the moderate quality reporting category. English and Spanish language articles did not differ on the number of indicators reported (8.1 vs. 8.3, respectively). However, Spanish articles reported more across reach indicators (62% vs. 43% of indicators), while English articles reported more across effectiveness indicators (69% vs 62%). Across RE-AIM dimensions, indicators for reach (48%), efficacy/effectiveness (67%), and implementation (41%) were reported more often than indicators of adoption (25%) and maintenance (10%). Few studies reported on the representativeness of participants, staff that delivered interventions, or the settings where interventions were adopted. Only 13% of the studies reported on quality of life and/or potential negative outcomes, 20% reported on intervention fidelity, and 11% on cost of implementation

The 3rd International Conference on Science & Engineering in Mathematics, Chemistry and Physics 2015 (ScieTech 2015), was held at The Westin Resort Nusa Dua, Bali on 31 January - 1 February 2015. The ScieTech 2015 conference is aimed to bring together researchers, engineers and scientists from around the world. ScieTech 2015 is placed on promoting interaction between the theoretical, experimental, and applied communities, so that a high level exchange is achieved in new and emerging areas within mathematics, chemistry and physics. As we already know that science and technology have brought tremendous benefits for human civilization. People are becoming healthier, wealthier, better educated, more peaceful, increasingly connected, and living longer. Of course, science and technology provide many answers to global challenges, but we will face more complex problems in the next decade due to increasing world population, limitation of energy, and climate change. Therefore, researchers should be more active in conducting research that enables collaboration between one and the others. Interdisciplinary cooperation is absolutely necessary in order to create a smart system for solving the global problems. We need a global and general long-term view of the future with long-range goals for solving complex problems in next decade. Therefore the conference was held to be a forum for researchers from different disciplines to start collaborating and conducting research that provides a solution to the global issues. The theme of ScieTech 2015 was ''The interdisciplinary Application between Mathematics, Chemistry and Physics to enhance the Quality of Life''. We would like to express our sincere gratitude to all in the Technical Program Committee who have reviewed the papers and developed a very interesting conference program as well as the invited and plenary speakers. This year, we received 197 papers and after rigorous review, 59 papers were accepted. The participants came from 19
Background Multiple Sclerosis (MS) is a common neurodegenerative disease, which often has a devastating effect on physical and emotional wellbeing of people with MS (PwMS). Several studies have shown positive effects of physical activity (PA) on disability, health related quality of life (HRQOL), and other outcomes. However, many studies include only people with mild disability making it difficult to generalize findings to those with moderate or severe disability. This study investigated the associations between PA and HRQOL, relapse rate (RR), disability, and demographic variables in PwMS with varying disability. Methods Through online platforms this large international survey recruited 2232 participants with MS who completed items regarding PA, MS and other health characteristics. Results PwMS who were younger (p < .001), male (p = 0.006), and with lower body mass index (BMI) (p < .001) undertook more PA, which was associated with decreased disability (p < 0.001) and increased HRQOL measures (all p < 0.001). For the subsample of people with relapsing-remitting MS, PA was associated with a decreased RR (p = 0.009). Regression analyses showed that increased PA predicted clinically significant improvements in HRQOL while controlling for level of disability, age and gender. More specifically, increasing from low to moderate and to high PA increased estimated mean physical health composite from 47.7 to 56.0 to 59.9 respectively (25.6% change), mental health composite from 60.6 to 67.0 to 68.8 (13.5% change), energy subscale from 35.9 to 44.5 to 49.8 (38.7% change), social function subscale from 57.8 to 66.1 to 68.4 (18.3% change), and overall QOL subscale from 58.5 to 64.5 to 67.7 (15.7% change). Conclusions For PwMS, regardless of disability level, increased PA is related to better HRQOL in terms of energy, social functioning, mental and physical health. These are important findings that should be taken into consideration by clinicians treating PwMS. PMID:25016312

The aims of this study were to assess and compare declared and real volume of physical activity (PA), and to evaluate correlations of these measurements with glycemic control (HbA1c) and body mass index (BMI), in patients with type 2 diabetes mellitus (T2DM). A group of 31 (16 women and 15 men) type 2 diabetic patients treated with insulin monotherapy, from (mean age=54 ± 3.6 years, BMI=29.7 ± 4.8 kg/m(2), T2DM treatment=9 ± 8 years, HbA1c 7 ± 1%) and not professionally active (unemployed or retired) was recruited. An assessment of energy cost (EC) of their weekly PA using International Physical Activity Questionnaire (IPAQ), and an accelerometer assessment was performed. Total energy expenditure of the declared weekly PA, calculated from the IPAQ (DPA) was 2513 ± 1349 METmin/week, and 2428 ± 1348, for male and female participants, respectively (p > 0.05). EC of the real PA (RPA), registered with the accelerometer was 4552 ± 2028 kcal/week, and 4032 ± 2288 kcal/week, for males, and females, respectively. Patients who demonstrated a high DPA, based on their IPAQ score, showed a significantly higher RPA, as registered by the accelerometer (p < 0.05). HbA1c and BMI did not correlate with their PA measurements. Our findings indicate that the IPAQ may serve as a potential tool for physical activity assessment with no further requirement for more sophisticated methods. Our results suggest that habitual physical activity has no impact on glycemic control and BMI in type 2 diabetic patients. However, further studies on a larger population are needed to explore these issues. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Wake vortices are generated by airplanes in flight. These vortices decay slowly and may persist for several minutes after their creation. These vortices and associated smaller scale turbulent structures present a hazard to incoming flights. It is for this reason that incoming flights are timed to arrive after these vortices have dissipated. Local weather conditions, mainly prevailing winds, can affect the transport and evolution of these vortices; therefore, there is a need to fully understand localized wind patterns at the airport-sized mircoscale. Here we have undertaken a computational investigation into the impacts of localized wind flows and physical structures on the velocity field at Atlantic City International Airport. The simulations are undertaken in OpenFOAM, an open source computational fluid dynamics software package, using an optimized geometric mesh of the airport. Initial conditions for the simulations are based on historical data with the option to run simulations based on projected weather conditions imported from the Weather Research & Forcasting (WRF) Model. Sub-grid scale turbulence is modeled using a Large Eddy Simulation (LES) approach. The initial results gathered from the WRF Model simulations and historical weather data analysis are presented elsewhere.

We examined if there were both direct and indirect relationships (via the drive for muscularity) between the perceived pressure to be muscular and internalization of the mesomorphic ideal, and if autonomy moderates these relationships in physically active men. A sample of 330 men, who were undergraduate students studying sport, completed the Behavioral Regulation in Exercise Questionnaire-2, the Mesomorphic Ideal Internalization subscale of the revised male version Sociocultural Attitudes Toward Appearance Questionnaire, the Perceived Sociocultural Pressure Scale-Modified, and the Drive for Muscularity Scale Attitudes subscale. Perceived pressure predicted internalization directly, and indirectly through the drive for muscularity. The direct relationship between pressure and internalization was weaker under higher levels of autonomy. The indirect path, via drive for muscularity, was stronger under higher levels of autonomy. These results provide insights into why men vary in the degree to which they internalize pressure to develop a mesomorphic ideal, supporting further examination of autonomy.

The present study examined age-related patterns in children's anxiety-related interpretations and internal attributions of physical symptoms. A large sample of 388 children aged between 4 and 13 years completed a vignette paradigm during which they had to explain the emotional response of the main character who experienced anxiety-related physical…
During the 1920s and 1930s, Italian physicists established strong relationships with scientists from other European countries and the United States. The career of Bruno Rossi, a leading personality in the study of cosmic rays and an Italian pioneer of this field of research, provides a prominent example of this kind of international cooperation. Physics underwent major changes during these turbulent years, and the traditional internationalism of physics assumed a more institutionalized character. Against this backdrop, Rossi's early work was crucial in transforming the study of cosmic rays into a branch of modern physics. His friendly relationships with eminent scientists--notably Enrico Fermi, Walther Bothe, Werner Heisenberg, Hans Bethe, and Homi Bhabha--were instrumental both for the exchange of knowledge about experimental practices and theoretical discussions, and for attracting the attention of physicists such as Arthur Compton, Louis Leprince-Ringuet, Pierre Auger and Patrick Blackett to the problem of cosmic rays. Relying on material from different archives in Europe and the United States, this case study aims to provide a glimpse of the intersection between national and international dimensions during the 1930s, at a time when the study of cosmic rays was still very much in its infancy, strongly interlaced with nuclear physics, and full of uncertain, contradictory, and puzzling results. Nevertheless, as a source of high-energy particles it became a proving ground for testing the validity of the laws of quantum electrodynamics, and made a fundamental contribution to the origins of particle physics.

Physical activity (PA) has been consistently implicated in the etiology of obesity, whereas recent evidence on the importance of sedentary time remains inconsistent. Understanding of dose-response associations of PA and sedentary time with overweight and obesity in adults can be improved with large-scale studies using objective measures of PA and sedentary time. The purpose of this study was to examine the strength, direction and shape of dose-response associations of accelerometer-based PA and sedentary time with body mass index (BMI) and weight status in 10 countries, and the moderating effects of study site and gender. Data from the International Physical activity and the Environment Network (IPEN) Adult study were used. IPEN Adult is an observational multi-country cross-sectional study, and 12 sites in 10 countries are included. Participants wore an accelerometer for seven consecutive days, completed a socio-demographic questionnaire and reported height and weight. In total, 5712 adults (18-65 years) were included in the analyses. Generalized additive mixed models, conducted in R, were used to estimate the strength and shape of the associations. A curvilinear relationship of accelerometer-based moderate-to-vigorous PA and total counts per minute with BMI and the probability of being overweight/obese was identified. The associations were negative, but weakened at higher levels of moderate-to-vigorous PA (>50 min per day) and higher counts per minute. No associations between sedentary time and weight outcomes were found. Complex site- and gender-specific findings were revealed for BMI, but not for weight status. On the basis of these results, the current Institute of Medicine recommendation of 60 min per day of moderate-to-vigorous PA to prevent weight gain in normal-weight adults was supported. No relationship between sedentary time and the weight outcomes was present, calling for further examination. If moderator findings are confirmed, the relationship

There is some evidence that physical activity (PA), sedentary time and screen time (ST) are associated with childhood obesity, but research is inconclusive and studies are mainly based on self-reported data. The literature is dominated by data from North American countries and there is a shortage of objective data from Malta which has one of the highest prevalences of childhood obesity in the world. The aims of this study were to assess the PA levels and ST patterns of Maltese boys and girls and how they compared with children in other countries while also examining differences in PA and ST by weight status. A nationally representative sample of 1126 Maltese boys and girls aged 10-11 years, of which 811 provided complete data. Physical activity was assessed using accelerometry, and ST by questionnaire. Body mass index (BMI) was computed from measured height and weight. Only 39% of boys and 10% of girls met the recommendation of one hour of daily MVPA. Comparison with international data indicated that mean MVPA (58.1 min for boys; 41.7 min for girls) was higher than in North America and Australia, but lower than in England. Girls were less active than boys at all measured times and spent less time in ST. A quarter of the children exceeded guidelines of two hours of TV on weekends, and double the amount on weekdays. Obese children were less active than normal weight children on weekdays and on weekends, reaching significance during the period after school, and they spent more time in ST than their normal weight counterparts. A low percentage of Maltese 10-11 year olds, particularly girls, reached the recommended levels of daily MVPA and spent large amounts of time engaged in screen time. Obese children were less active than non-obese children. As children spend most of their waking time at school and that activity during this time is less than one third of the daily requirements, aiming to increase MVPA at school for all Maltese children is likely to be an important

Objective The aim of this study was to explore the validity of self-rated health across different populations of older adults, when compared to the Short Physical Performance Battery. Design Cross-sectional analysis of the International Mobility in Aging Study. Setting Five locations: Saint-Hyacinthe and Kingston (Canada), Tirana (Albania), Manizales (Colombia), and Natal (Brazil). Participants Older adults between 65 and 74 years old (n = 1,995). Methods The Short Physical Performance Battery (SPPB) was used to measure physical performance. Self-rated health was assessed with one single five-point question. Linear trends between SPPB scores and self-rated health were tested separately for men and women at each of the five international study sites. Poor physical performance (independent variable) (SPPB less than 8) was used in logistic regression models of self-rated health (dependent variable), adjusting for potential covariates. All analyses were stratified by gender and site of origin. Results A significant linear association was found between the mean scores of the Short Physical Performance Battery and ordinal categories of self-rated health across research sites and gender groups. After extensive control for objective physical and mental health indicators and socio-demographic variables, these graded associations became non-significant in some research sites. Conclusion These findings further confirm the validity of SRH as a measure of overall health status in older adults. PMID:27089219

A moderate level of physical activity (PA), such as a daily 30-min walk, reduces cardiovascular risk. There is a lack of evidence about the cardiovascular benefits of PA below this recommendation of minimum PA level. We aimed to study the impact of a lower level of PA on cardiovascular health. Sixty-four overweight/obese men and women were enrolled in a community programme consisting of 4 months of 1h, low-intensity PA two days per week. Before and after the intervention, PA level (METs/h/wk), endogenous antioxidant status (SOD and GPX concentration and activity and oxidised LDL), ADMA concentrations, endothelial function by small artery reactive hyperaemia index (saRHI), and resting heart rate (RHR) were assessed. After the intervention, significant increases in saRHI (P=0.031), SOD and GPX activities, and a decrease in ADMA plasma concentrations, and RHR (P<0.001 for all) were observed. Increases in PA were positively associated with increases in saRHI (r=0.341, P=0.022), GPx (r=0.303, P=0.047) and decreases in RHR (r=-0.302, P=0.047). Multivariate analyses showed that independent predictors of saRHI improvement were an increase in PA (2.65, 95%CI: 1.21-4.01), decrease in RHR (1.91, 95%CI: 1.01-4.98), and an increase in GPx (2.61, 95%CI: 1.16-5.01). In obese and overweight men and women, an increase in PA, even below the minimal international recommendations, improves antioxidant capacity, RHR and peripheral small artery reactivity.

The International Physical Activity Questionnaire Short Form (IPAQ-SF) is a self-report questionnaire commonly used in patients with rheumatoid arthritis (RA) to measure physical activity. However, despite its frequent use in patients with RA, its validity has not been ascertained in this population. The aim of this study was to examine the criterion validity of energy expenditure from physical activity recorded with the IPAQ-SF in patients with RA compared with the objective criterion measure, the SenseWear Armband (SWA) which has been validated previously in this population. Cross-sectional criterion validation study. Regional hospital outpatient setting. Twenty-two patients with RA attending outpatient rheumatology clinics. Subjects wore an SWA for 7 full consecutive days and completed the IPAQ-SF. Energy expenditure from physical activity recorded by the SWA and the IPAQ-SF. Energy expenditure from physical activity recorded by the IPAQ-SF and the SWA showed a small, non-significant correlation (r=0.407, P=0.60). The IPAQ-SF underestimated energy expenditure from physical activity by 41% compared with the SWA. This was corroborated using Bland and Altman plots, as the IPAQ-SF was found to overestimate energy expenditure from physical activity in nine of the 22 individuals, and underestimate energy expenditure from physical activity in the remaining 13 individuals. The IPAQ-SF has limited use as an accurate and absolute measure for estimating energy expenditure from physical activity in patients with RA. Copyright © 2014 Chartered Society of Physiotherapy.

This investigation examined the relation between developmental trajectories jointly estimated for social and physical aggression and adjustment problems at age 14. Teachers provided ratings of children's social and physical aggression in Grades 3, 4, 5, 6, and 7 for a sample of 255 children (131 girls, 21% African American, 52% European American, 21% Mexican American). Participants, parents, and teachers completed measures of the adolescent's adjustment to assess internalizing symptoms, rule-breaking behaviors, and borderline and narcissistic personality features. Results showed that membership in a high and rising trajectory group predicted rule-breaking behaviors and borderline personality features. Membership in a high desister group predicted internalizing symptoms, rule-breaking behaviors, and borderline and narcissistic personality features. The findings suggest that although low levels of social and physical aggression may not bode poorly for adjustment, individuals engaging in high levels of social and physical aggression in middle childhood may be at greatest risk for adolescent psychopathology, whether they increase or desist in their aggression through early adolescence.

This commentary paper provides a selective overview of topics addressed at the sixth annual meeting of the International Society of Behavioral Nutrition and Physical Activity (ISBNPA). With 31 symposiums, 42 free paper sessions and 236 poster presentations ISBNPA 2007 provided a comprehensive overview of the state of the art and of new avenues for behavioral nutrition and physical activity research. Research presented at the conference helps to identify and specify important nutrition and physical activity behaviors for health promotion, as well as the correlates, predictors and determinants of these behaviors, and to build and test intervention strategies that go beyond traditional health education. ISBNPA 2007 also indicates that ISBNPA should strive to become more international by inclusion of more scientists from countries outside North America, Western Europe and Australia. ISBNPA should maintain its encouragement of research that is firmly rooted in behavioral theory and research that goes beyond applying cross-sectional research designs, and that addresses the most important public health issues associated with behavioral nutrition and physical activity.

This paper summarizes the conference presentations that specifically dealt with the role of the physics department in education of teachers, both before they begin teaching (pre-service) and during their careers (in-service). These presentations in general reflected a consensus that, as in the case of other students, instruction in pre-service and in-service courses should employ more active engagement techniques, both to improve student understanding and to model effective instruction, and that the appropriate use of technology can be a powerful aid to that end. Improvements made in standard introductory physics courses will impact most future secondary science teachers who, by and large, will have science degrees or take a significant amount of science courses. However, pre-service elementary teachers take few science courses and are often science phobic. This population represents the vast bulk of teachers who, if they have a good understanding of basic science, can engage children at the ages when they are most curious. Physics departments can play a valuable role in stimulating and sustaining reform of pre-college science teaching by being more involved in providing effective and appropriate instruction and models for inquiry to current and future elementary and secondary teachers.

To develop a new quality-of-life (QoL) instrument with international validity that specifically assesses cosmetic products and physical appearance. In the first phase, semidirected interviews involved 309 subjects. In the second stage, an acceptability study was performed on 874 subjects. Thereafter, we recruited a total of 3231 subjects, each of whom completed the BeautyQoL questionnaire, a clinical checklist for the skin, the generic QoL 36-Item Short Form Health Survey, and a sociodemographic questionnaire. A retest was performed 8 days later on a subgroup of 652 subjects. Populations in France, the United Kingdom, Germany, Spain, Sweden, Italy, Russia, the United States, Brazil, Japan, India, China, and South Africa, representing 16 languages. The general adult healthy population, including women and men. Psychometric properties, construct validity, reproducibility, and internal and external consistency. General acceptability was very good in the 16 languages, with a very low rate of no answers. The validation phase reduced the questionnaire to 42 questions structured in the following 5 dimensions that explained 76.7% of the total variance: social life, self-confidence, mood, energy, and attractiveness. Internal consistency was high (Cronbach α coefficients, 0.93-0.98). Reproducibility at 8 days was satisfactory in all dimensions. Results of external validity testing revealed that BeautyQoL scores correlated significantly with all 36-Item Short Form Health Survey scores except for physical function. These results demonstrate the validity and reliability of the BeautyQoL questionnaire as the very first international instrument specific to cosmetic products and physical appearance.

This paper examines men's lifetime physical intimate partner violence (IPV) perpetration across eight low- and middle-income countries to better understand key risk factors that interventions can target in order to promote gender equality and reduce IPV. We use data from men (n = 7806) that were collected as part of the International Men and Gender Equality Survey (IMAGES) in Bosnia and Herzegovina, Brazil, Chile, Croatia, Democratic Republic of Congo (DRC), India, Mexico, and Rwanda. Results show that there is wide variation across countries for lifetime self-reported physical violence perpetration (range: 17% in Mexico to 45% in DRC), men's support for equal roles for men and women, and acceptability of violence against women. Across the sample, 31% of men report having perpetrated physical violence against a partner in their lifetime. In multivariate analyses examining risk factors for men ever perpetrating physical violence against a partner, witnessing parental violence was the strongest risk factor, reinforcing previous research suggesting the inter-generational transmission of violence. Additionally, having been involved in fights not specifically with an intimate partner, permissive attitudes towards violence against women, having inequitable gender attitudes, and older age were associated with a higher likelihood of ever perpetrating physical IPV. In separate analyses for each country, we found different patterns of risk factors in countries with high perpetration compared to countries with low perpetration. Findings are interpreted to identify key knowledge gaps and directions for future research, public policies, evaluation, and programming.

Background The quantity and quality of studies in child and adolescent physical activity and sedentary behaviour have rapidly increased, but research directions are often pursued in a reactive and uncoordinated manner. Aim To arrive at an international consensus on research priorities in the area of child and adolescent physical activity and sedentary behaviour. Methods Two independent panels, each consisting of 12 experts, undertook three rounds of a Delphi methodology. The Delphi methodology required experts to anonymously answer questions put forward by the researchers with feedback provided between each round. Results The primary outcome of the study was a ranked set of 29 research priorities that aimed to be applicable for the next 10 years. The top three ranked priorities were: developing effective and sustainable interventions to increase children’s physical activity long-term; policy and/or environmental change and their influence on children’s physical activity and sedentary behaviour; and prospective, longitudinal studies of the independent effects of physical activity and sedentary behaviour on health. Conclusions These research priorities can help to guide decisions on future research directions. PMID:24228891
International Space Station (ISS) astronauts receive supervised physical training pre-flight, utilize exercise countermeasures in-flight, and participate in a structured reconditioning program post-flight. Despite recent advances in exercise hardware and prescribed exercise countermeasures, ISS crewmembers are still found to have variable levels of deconditioning post-flight. This presentation provides an overview of the astronaut medical certification requirements, pre-flight physical training, in-flight exercise countermeasures, and the post-flight reconditioning program. Astronauts must meet medical certification requirements on selection, annually, and prior to ISS missions. In addition, extensive physical fitness testing and standardized medical assessments are performed on long duration crewmembers pre-flight. Limited physical fitness assessments and medical examinations are performed in-flight to develop exercise countermeasure prescriptions, ensure that the crewmembers are physically capable of performing mission tasks, and monitor astronaut health. Upon mission completion, long duration astronauts must re-adapt to the 1 G environment, and be certified as fit to return to space flight training and active duty. A structured, supervised postflight reconditioning program has been developed to prevent injuries, facilitate re-adaptation to the 1 G environment, and subsequently return astronauts to training and space flight. The NASA reconditioning program is implemented by the Astronaut Strength, Conditioning, and Rehabilitation (ASCR) team and supervised by NASA flight surgeons. This program has evolved over the past 10 years of the International Space Station (ISS) program and has been successful in ensuring that long duration astronauts safely re-adapt to the 1 g environment and return to active duty. Lessons learned from this approach to managing deconditioning can be applied to terrestrial medicine and future exploration space flight missions.

Physical activity (PA) during pregnancy has significant health benefits for the mother and her child; however, many women reduce their activity levels during pregnancy and most are not sufficiently active. Given the important health benefits of PA during pregnancy, evidence that supports research translation is vital. To determine the extent to which physical activity interventions for pregnant women report on internal and external validity factors using the RE-AIM framework (reach, efficacy/effectiveness, adoption, implementation, and maintenance). Ten databases were searched up to 1 June 2015. Eligible published papers and unpublished/grey literature were identified using relevant search terms. Studies had to report on physical activity interventions during pregnancy, including measures of physical activity during pregnancy at baseline and at least one point post-intervention. Randomised controlled trials and quasi-experimental studies that had a comparator group were included. Reporting of RE-AIM dimensions were summarised and synthesised across studies. The reach (72.1%) and efficacy/effectiveness (71.8%) dimensions were commonly reported; however, the implementation (28.9%) and adoption (23.2%) dimensions were less commonly reported and no studies reported on maintenance. This review highlights the under-reporting of issues of contextual factors in studies of physical activity during pregnancy. The translation of physical activity interventions during pregnancy could be improved through reporting of representativeness of participants, clearer reporting of outcomes, more detail on the setting and staff who deliver interventions, costing of interventions and the inclusion of process evaluations and qualitative data. The systematic review highlights the under-reporting of contextual factors in studies of physical activity during pregnancy. © 2016 Royal College of Obstetricians and Gynaecologists.

This paper addresses the problem of estimating the present value of electrochemical internal variables in a lithium-ion cell in real time, using readily available measurements of cell voltage, current, and temperature. The variables that can be estimated include any desired set of reaction flux and solid and electrolyte potentials and concentrations at any set of one-dimensional spatial locations, in addition to more standard quantities such as state of charge. The method uses an extended Kalman filter along with a one-dimensional physics-based reduced-order model of cell dynamics. Simulations show excellent and robust predictions having dependable error bounds for most internal variables.more » (C) 2014 Elsevier B.V. All rights reserved.« less

To identify intervention categories encountered by physical therapists working in aquatic therapy with disabled children, using the International Classification of Functioning, Disability and Health-Children and Youth (ICF-CY). Aquatic physical therapists were asked to describe concepts related to the functioning of disabled children and their contextual factors. Data were collected in three rounds using the Delphi technique. All answers were translated ('linked') to the ICF-CY and analyzed to determine the degree of consensus. Answers were linked and organized into four diagnostic groups. Overall, in the four groups, 41 Body Functions, 8 Body Structures, 36 Activities and Participation, and 6 Environmental Factors categories were identified as intervention targets. In addition, 8 Environmental Factors that influence aquatic physical therapy were identified. This study highlights the variety of intervention categories available to aquatic physical therapists when treating children in the water.

Starting in 1989 we have created a forum at the International Centre for Theoretical Physics, Trieste, where scientists from different parts of the world can meet and exchange information in the frontier areas of physics. In the three previous meetings, we focused on large amplitude waves and fields in plasmas, the physics of dusty plasmas, and wave-particle interactions and energization in plasmas. In 1995, we came up with a fresh idea of organizing somewhat enlarged but still well focused research topics that are cross-disciplinary. Thus, the usual 'fourth-week activity' of the Plasma Physics College at the ICTP was replaced by an International Topical Workshop on Plasma Physics: Coherent Processes in Nonlinear Media, which was held at the ICTP during the period 16-20 October, 1995. This provided us an opportunity to draw eminent speakers from many closely related fields such as plasma physics, fluid dynamics, nonlinear optics, and astrophysics. The Workshop was attended by 82 delegates from 34 countries, and the participation from the industrial and the developing countries was about half each. The programme included 4 review and 29 topical invited lectures. In addition, about 30 contributed papers were presented as posters in two sessions. The latter were created in order to give opportunities to younger physicists for displaying the results of their recent work and to obtain constructive comments from the other participants. During the five days at the ICTP, we focused on almost all the various aspects of nonlinear phenomena that are common in different branches of science. The review and topical lectures as well as the posters dealt with the most recent advances in coherent nonlinear processes in space and astrophysical plasmas, in fluids and optics, in low temperature dusty plasmas, as well as in laser produced and magnetically confined laboratory plasmas. The focus was on the physics of various types of waves and their generation mechanisms, the development

Questionnaire survey explored perception, attitude and instructional preferences with respect to gender and nationality in high school students of India and USA, a sample of 1101 Indian and 458 US students. Descriptive Statistics techniques were adopted for analysis. Male and female students in USA were at the high and low ends of the spectrum, respectively, in perception and attitude. Preference on instructional strategies was found to be independent of nationality, exposed strategies, opting science, class size and facilities. Responses from both countries indicate preference for an integrated instructional strategy that has strong teacher involvement in a student-centered framework. A thoughtful and properly designed instructional strategy could provide sufficient elements in modifying students' epistemological beliefs. Understanding the nature and process of physics along with a better learning outcome is usually not possible by administering student-centered or teacher-centered strategies alone in their purest form. This study provides adequate support in obtaining two equally significant but contrasting goals in Physics Education Research, to gain conceptual development with increased interest and attainment in learners, through integration.
Developing post-disaster physical rehabilitation: role of the World Health Organization Liaison Sub-Committee on Rehabilitation Disaster Relief of the International Society of Physical and Rehabilitation Medicine.
Gosney, James; Reinhardt, Jan Dietrich; Haig, Andrew J; Li, Jianan
This special report presents the role of the World Health Organization (WHO) Liaison Sub-Committee on Rehabilitation Disaster Relief (CRDR) of the International Society of Physical and Rehabilitation Medicine (ISPRM) in developing an enhanced physical rehabilitation relief response to large-scale natural disasters. The CRDR has stated that disaster rehabilitation is an emerging subspecialty within physical and rehabilitation medicine (PRM). In reviewing the existing literature it was found that large natural disasters result in many survivors with disabling impairments, that these survivors may have better clinical outcomes when they are treated by PRM physicians and teams of rehabilitation professionals, that the delivery of these rehabilitation services to disaster sites is complicated, and that their absence can result in significant negative consequences for individuals, communities and society. To advance its agenda, the CRDR sponsored an inaugural Symposium on Rehabilitation Disaster Relief as a concurrent scientific session at the 2011 ISPRM 6th World Congress in San Juan, Puerto Rico. The symposium included oral and poster presentations on a range of relevant topics and concluded with an international non-governmental organization panel discussion that addressed the critical question "How can rehabilitation actors coordinate better in disaster?" Building upon the symposium, the CRDR is developing a disaster rehabilitation evidence-base, which will inform and educate the global professional rehabilitation community about needs and best practices in disaster rehabilitation. The Journal of Rehabilitation Medicine (JRM) has commissioned this special report to announce a series of papers on disaster rehabilitation from the symposium's scientific programme. Authors are invited to submit papers on the topic for inclusion in this special series. JRM also encourages expert commentary in the form of Letters to the Editor.

This paper describes the methods employed to apply probabilistic modeling techniques to the International Space Station (ISS) power system. These techniques were used to quantify the probabilistic variation in the power output, also called the response variable, due to variations (uncertainties) associated with knowledge of the influencing factors called the random variables. These uncertainties can be due to unknown environmental conditions, variation in the performance of electrical power system components or sensor tolerances. Uncertainties in these variables, cause corresponding variations in the power output, but the magnitude of that effect varies with the ISS operating conditions, e.g. whether or not the solar panels are actively tracking the sun. Therefore, it is important to quantify the influence of these uncertainties on the power output for optimizing the power available for experiments.

We report the development of internal coordinate mechanics force field (ICMFF), new force field parameterized using a combination of experimental data for crystals of small molecules and quantum mechanics calculations. The main features of ICMFF include: (a) parameterization for the dielectric constant relevant to the condensed state (ε = 2) instead of vacuum, (b) an improved description of hydrogen-bond interactions using duplicate sets of van der Waals parameters for heavy atom-hydrogen interactions, and (c) improved backbone covalent geometry and energetics achieved using novel backbone torsional potentials and inclusion of the bond angles at the C(α) atoms into the internal variable set. The performance of ICMFF was evaluated through loop modeling simulations for 4-13 residue loops. ICMFF was combined with a solvent-accessible surface area solvation model optimized using a large set of loop decoys. Conformational sampling was carried out using the biased probability Monte Carlo method. Average/median backbone root-mean-square deviations of the lowest energy conformations from the native structures were 0.25/0.21 Å for four residues loops, 0.84/0.46 Å for eight residue loops, and 1.16/0.73 Å for 12 residue loops. To our knowledge, these results are significantly better than or comparable with those reported to date for any loop modeling method that does not take crystal packing into account. Moreover, the accuracy of our method is on par with the best previously reported results obtained considering the crystal environment. We attribute this success to the high accuracy of the new ICM force field achieved by meticulous parameterization, to the optimized solvent model, and the efficiency of the search method. © 2010 Wiley-Liss, Inc.

Ion cyclotron range of frequency (ICRF) heating is foreseen as an integral component of the initial ITER operation. The status of ICRF preparations for ITER and supporting research were updated in the 2007 [Gormezano et al., Nucl. Fusion 47, S285 (2007)] report on the ITER physics basis. In this report, we summarize progress made toward the successful application of ICRF power on ITER since that time. Significant advances have been made in support of the technical design by development of new techniques for arc protection, new algorithms for tuning and matching, carrying out experimental tests of more ITER like antennas and demonstration on mockups that the design assumptions are correct. In addition, new applications of the ICRF system, beyond just bulk heating, have been proposed and explored.

Recently the experimentalists in Krasznahorkay (2016)  announced observing an unexpected enhancement of the e+-e- pair production signal in one of the 8Be nuclear transitions. The subsequent studies have been focused on possible explanations based on introducing new types of particle. In this work, we improve the nuclear physics modeling of the reaction by studying the pair emission anisotropy and the interferences between different multipoles in an effective field theory inspired framework, and examine their possible relevance to the anomaly. The connection between the previously measured on-shell photon production and the pair production in the same nuclear transitions is established. These improvements, absent in the original experimental analysis, should be included in extracting new particle's properties from the experiment of this type. However, the improvements can not explain the anomaly. We then explore the nuclear transition form factor as a possible origin of the anomaly, and find the required form factor to be unrealistic for the 8Be nucleus. The reduction of the anomaly's significance by simply rescaling our predicted event count is also investigated.

Although studies have begun to shed light on medical students' attitudes towards peer physical examination (PPE), they have been conducted at single sites, and have generally not examined changes in medical students' attitudes over time. Employing both cross-sectional and longitudinal designs, the current study examines medical students' attitudes towards PPE at schools from different geographical and cultural regions and assess changes in their attitudes over their first year of medical study. Students at six schools (Peninsula, UK; Durham, UK; Auckland, New Zealand; Flinders, Australia; Sapporo, Japan and Li Ka Shing, Hong Kong) completed the Examining Fellow Students (EFS) questionnaire near the start of their academic year (T1), and students at four schools (Peninsula, Durham, Auckland and Flinders) completed the EFS for a second time, around the end of their academic year (T2). Univariate and multivariate analyses revealed a high level of acceptance for PPE of non-intimate body regions amongst medical students from all schools (greater than 83%, hips, at T1 and 94.5%, hips and upper body, at T2). At T1 and T2, students' willingness to engage in PPE was associated with their gender, ethnicity, religiosity and school. Typically, students least comfortable with PPE at T1 and T2 were female, non-white, religious and studying at Auckland. Although students' attitudes towards PPE were reasonably stable over their first year of study, and after exposure to PPE, we did find some statistically significant differences in attitudes between T1 and T2. Interestingly, attitude changes were consistently predicted by gender, even when controlling for school. While male students' attitudes towards PPE were relatively stable over time, females' attitudes were changeable. In this paper, we discuss our findings in light of existing research and theory, and discuss their implications for educational practice and further research.

Participation in physical activity (PA) decreases after the onset of a spinal cord injury (SCI) and is generally low in persons with SCI. To provide an overview of findings on correlates/determinants of PA in persons with SCI applying the International Classification of Functioning, Disability and Health (ICF) to analyze and report results. A systematic literature review using the databases MEDLINE, PsycINFO, SSCI, and CINHAL was conducted. Independent variables were extracted and linked to ICF codes. Quality of evidence was rated using internationally accepted standards. Overall, evidence quality of the 25 included studies is low. Environmental Factors were consistently found as correlates of PA, whereas Personal Factors (socio-demographics and psychological constructs) were weakly associated with PA in the SCI population. Associations with Body Functions, Body Structures, Activities and Participation and Health Conditions were less frequently studied. Although quality of evidence of reviewed literature is low, results indicate that rather environmental barriers than the 'classical' socio-demographic factors known from social epidemiology correlate with PA in persons with SCI. There is insufficient evidence to draw conclusions concerning the association of Body Functions and Structures and Activity and Participation with PA. Future research is encouraged to better understand the interplay between functioning, contextual factors, health conditions and PA in SCI to establish a sound basis for intervention planning in this special needs population. In addition, our experience showed that linking study results to the ICF facilitates data analysis and reporting. Copyright © 2012 Elsevier Inc. All rights reserved.

The International Physical Activity Questionnaire (IPAQ) is commonly used in surveys, but reliability and validity has not been established in the Danish population. Among participants in the Danish Health Examination survey 2007-2008, 142 healthy participants (45% men) wore a unit that combined accelerometry and heart rate monitoring (Acc+HR) for 7 consecutive days and then completed the IPAQ. Background data were obtained from the survey. Physical activity energy expenditure (PAEE) and time in moderate, vigorous, and sedentary intensity levels were derived from the IPAQ and compared with estimates from Acc+HR using Spearman's correlation coefficients and Bland-Altman plots. Repeatability of the IPAQ was also assessed. PAEE from the 2 methods was significantly positively correlated (0.29 and 0.49; P = 0.02 and P < 0.001; for women and men, respectively). Men significantly overestimated PAEE by IPAQ (56.2 vs 45.3 kJ/kg/day, IPAQ: Acc+HR, P < .01), while the difference was nonsignificant for women (40.8 vs 44.4 kJ/kg/day). Bland-Altman plots showed that the IPAQ overestimated PAEE, moderate, and vigorous activity without systematic error. Reliability of the IPAQ was moderate to high for all domains and intensities (total PAEE intraclass correlation coefficient = 0.58). This Danish Internet-based version of the long IPAQ had modest validity and reliability when assessing PAEE at population level.

Although the existing literature on immigrant mental health is extensive, major substantive and methodological gaps remain. Substantively, there is little population-based research that focuses on the mental health consequences of migration for Vietnamese Americans. More generally, although a wide range of mental health problems among immigrants has been identified, the potential causal or mediating mechanisms underlying these problems remain elusive. This latter substantive shortcoming is related to a key methodological challenge involving the potentially confounding effects of selection on migration-related outcomes. This article addresses these challenges by employing a "natural experiment" design, involving comparisons among three population-based samples of Vietnamese immigrants, never-leavers, and returnees (N=709). Data were collected in Ho Chi Minh City and in New Orleans between 2003 and 2005. The study investigates the long-term impact of international migration on Vietnamese mental health, and the potential mediating effects of social networks and physical health on these migration-related outcomes. The results reveal both mental health advantages and disadvantages among Vietnamese immigrants relative to the two groups of Vietnamese nationals. Selection can be ruled out for some of these differences, and both social networks and physical health are found to play important explanatory roles.

This volume contains papers presented at the International Fröhlich's Symposium entitled 'Electrodynamic Activity of Living Cells' (1-3 July 2011, Prague, Czech Republic). The Symposium was the 9th meeting devoted to physical processes in living matter organized in Prague since 1987. The hypothesis of oscillation systems in living cells featured by non-linear interaction between elastic and electrical polarization fields, non-linear interactions between the system and the heat bath leading to energy downconversion along the frequency scale, energy condensation in the lowest frequency mode and creation of a coherent state was formulated by H Fröhlich, founder of the theory of dielectric materials. He assumed that biological activity is based not only on biochemical but also on biophysical mechanisms and that their disturbances form basic links along the cancer transformation pathway. Fröhlich outlined general ideas of non-linear physical processes in biological systems. The downconversion and the elastic-polarization interactions should be connected in a unified theory and the solution based on comprehensive non-linear characteristics. Biochemical and genetic research of biological systems are highly developed and have disclosed a variety of cellular and subcellular structures, chemical reactions, molecular information transfer, and genetic code sequences - including their pathological development. Nevertheless, the cancer problem is still a big challenge. Warburg's discovery of suppressed oxidative metabolism in mitochondria in cancer cells suggested the essential role of physical mechanisms (but his discovery has remained without impact on cancer research and on the study of physical properties of biological systems for a long time). Mitochondria, the power plants of the cell, have several areas of activity-oxidative energy production is connected with the formation of a strong static electric field around them, water ordering, and liberation of non

Günther Bauer Günther Bauer. This special issue of Journal of Physics: Condensed Matter is devoted to Günther Bauer, who celebrated his 65th birthday in September 2007. Günther has had a long career in condensed matter physics, but is known particularly for his studies of high magnetic field transport and optics in semiconductors and, more recently, for the discovery and x-ray analysis of self-organized 3D quantum dot crystals. However, his work is much broader than this, as indicated by the wide selection of topics which are represented in this special issue. Günther began his scientific career in Vienna, became associate Professor at the University of Ulm after habilitation at the Rheinisch-Westfälische Technische Hochschule Aachen, Germany, and then ascended to a full professorship at the Montanuniversität, Leoben, Austria, in 1980. He subsequently moved to the Johannes Kepler Universität, Linz, Austria, in 1990. Apart from his outstanding scientific achievements, Günther is also known for organizing the biannual winterschool on 'New Developments in Solid State Physics' beginning in 1980. Initially, he worked at this task together with Helmut Heinrich (until 2000) and Friedl Kuchar (1984 until now) and subsequently with Wolfgang Jantsch (who followed Helmut Heinrich in 2002). This winterschool was, and remains, very important in identifying new trends in solid state physics, and thus has a number of important proponents in the scientific community. It was at one of the first of these winterschools where the initial reports of the quantum Hall effect were presented, and it has been a meeting place where established experts (including three Nobel laureates) teach, and interact with students and young researchers. It is important to know that Günther's excellent international connections were necessary to maintain the high level of the winterschool over almost 30 years. After the first meeting in 1980 in Mariapfarr, these winterschools were held thirteen

Developing accessible Web-based materials to support diabetes self-management in people with lower levels of health literacy is a continuing challenge. The objective of this international study was to develop a Web-based intervention promoting physical activity among people with type 2 diabetes to determine whether audiovisual presentation and interactivity (quizzes, planners, tailoring) could help to overcome the digital divide by making digital interventions accessible and effective for people with all levels of health literacy. This study also aimed to determine whether these materials can improve health literacy outcomes for people with lower levels of health literacy and also be effective for people with higher levels of health literacy. To assess the impact of interactivity and audiovisual features on usage, engagement, and health literacy outcomes, we designed two versions of a Web-based intervention (one interactive and one plain-text version of the same content) to promote physical activity in people with type 2 diabetes. We randomly assigned participants from the United Kingdom, Austria, Germany, Ireland, and Taiwan to either an interactive or plain-text version of the intervention in English, German, or Mandarin. Intervention usage was objectively recorded by the intervention software. Self-report measures were taken at baseline and follow-up (immediately after participants viewed the intervention) and included measures of health literacy, engagement (website satisfaction and willingness to recommend the intervention to others), and health literacy outcomes (diabetes knowledge, enablement, attitude, perceived behavioral control, and intention to undertake physical activity). In total, 1041 people took part in this study. Of the 1005 who completed health literacy information, 268 (26.67%) had intermediate or low levels of health literacy. The interactive intervention overall did not produce better outcomes than did the plain-text version. Participants in

Physical activity questionnaires (PAQ) have been extensively used to determine physical activity (PA) levels. Most PAQ are derived from an energy expenditure-based perspective and assess activities with a certain intensity level. Activities with a moderate or vigorous intensity level are predominantly used to determine a person's PA level in terms of quantity. Studies show that the time spent engaging in moderate and vigorous intensity PA does not appropriately reflect the actual PA behavior of older people because they perform more functional, everyday activities. Those functional activities are more likely to be considered low-intense and represent an important qualitative health-promoting activity. For the elderly, functional, light intensity activities are of special interest but are assessed differently in terms of quantity and quality. The aim was to analyze the content of PAQ for the elderly. N = 18 sufficiently validated PAQ applicable to adults (60+) were included. Each item (N = 414) was linked to the corresponding code of the International Classification of Functioning, Disability and Health (ICF) using established linking rules. Kappa statistics were calculated to determine rater agreement. Items were linked to 598 ICF codes and 62 different ICF categories. A total of 43.72% of the codes were for sports-related activities and 14.25% for walking-related activities. Only 9.18% of all codes were related to household tasks. Light intensity, functional activities are emphasized differently and are underrepresented in most cases. Additionally, sedentary activities are underrepresented (5.55%). κ coefficients were acceptable for n = 16 questionnaires (0.48-1.00). There is a large inconsistency in the understandings of PA in elderly. Further research should focus (1) on a conceptual understanding of PA in terms of the behavior of the elderly and (2) on developing questionnaires that inquire functional, light intensity PA, as well as sedentary

Scientific congresses are an important tool to support communication among scientists, enabling exchange of knowledge and discussion of research results. They can also provide specialist education and allow a forum in which to develop the goals and policies of scientific societies. The World Congresses of the International Society of Physical and Rehabilitation Medicine (ISPRM) aims at continuous improvement of congress quality. The programme development aims are: to operate at the highest possible scientific level; to guarantee continuous communication within the main areas of science in the field; and to invite experts to present topics of recent interest. The first section, the basic programme, largely comprises original papers selected from submitted abstracts. The second section covers topics of recent interest in more depth. Other sessions include recent topics arising from the ISPRM-World Health Organization (ISPRM-WHO) liaison, collaborative sessions with other societies, including national societies special interest sessions and ISPRM partners, and sessions organized by young scientists and students. These aims and programme guide the organizers of the 9th World Congress, which will be held on 19-23 June 2015 in Berlin. The concepts described here will be developed further for use in future ISPRM World Congresses.

As physical therapy (PT) and occupational therapy (OT) educational programs endeavor to foster core values of social responsibility, justice, and altruism in an increasingly global community, the incorporation of local and international service-learning (ISL) into the curriculum is growing. Much of the research has focused on the measurement of student learning, with little written about the impact on the host community. Proponents of global health initiatives are calling for consideration of all stakeholders to ensure ethical practice. This paper explores the current literature related to PT and OT ISL and builds a conceptual framework for ISL course planning. The essential phases in the framework include: 1) pre-experience planning/preparation stage, 2) field immersion experience stage, and 3) postexperience stage. The essential elements are: 1) cultural competency training, 2) communication and coordination with community, 3) comprehensive assessment, and 4) strategic planning. The authors suggest this framework as a practical tool to structure ISL courses with an explicit emphasis on ethical concerns. Additionally, they seek to foster more dialogue and action related to the promotion of ethical practices in ISL in PT and OT education programs.

The International Classification of Functioning, Disability and Health (ICF) Generic- 30 Set (previously referred to as Rehabilitation Set) is a minimal set of ICF categories for reporting and assessing functioning and disability in clinical populations with different health conditions along the continuum of care. Recently, the Italian Society of Physical and Rehabilitation Medicine (SIMFER) developed an Italian modification of the simple and intuitive descriptions (SID) of these categories. This study was the first one to implement the use of the SID in practice. 1) To implement the use of the ICF in clinical practice and research among Italian Residents in PRM. 2) To verify if the SID made the application of ICF Generic 30 Set more user-friendly than the original descriptions. 3) To examine the prevalence of functioning problems of patients accessing Rehabilitation Services to serve as reference for the development of an ICF-based clinical data collection tool. Multicenter cross-sectional study. Italian Physical Medicine and Rehabilitation (PRM) outpatient rehabilitation services. Patients referring to Italian PRM outpatient rehabilitation services and Italian Residents in PRM. Each School of Specialization involved, randomly, received the ICF Generic-30 Set with the original descriptions or with the SID. Residents collected over a 4-month period (April-July 2016) patients data related to the ICF Generic-30 Set categories. Moreover, the residents self- assessed their difficulty in using the ICF Generic-30 Set with the original descriptions or with the SID, through a Numeric Rating Scale (NRS). Ninety-three residents collected functioning data of 864 patients (mean aged 57.7±19.3) with ICF Generic-30 Set: 304 with the original descriptions and 560 with SID. The difficulty in using the ICF Generic-30 Set with SID was rated as lower than using the original descriptions (NRS ￼= 2.8±2.5 vs 3.5±3.1; p<0.001). The most common disease was the back pain (9.6%) and

To investigate the reliability and an aspect of validity of a modified version of the long International Physical Activity Questionnaire (Hausa IPAQ-LF) in Nigeria. Cross-sectional study, examining the reliability and construct validity of the Hausa IPAQ-LF compared with anthropometric and biological variables. Metropolitan Maiduguri, the capital city of Borno State in Nigeria. 180 Nigerian adults (50% women) with a mean age of 35.6 (SD=10.3) years, recruited from neighbourhoods with diverse socioeconomic status and walkability. Domains (domestic physical activity (PA), occupational PA, leisure-time PA, active transportation and sitting time) and intensities of PA (vigorous, moderate and walking) were measured with the Hausa IPAQ-LF on two different occasions, 8 days apart. Outcomes for construct validity were measured body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP). The Hausa IPAQ-LF demonstrated good test-retest reliability (intraclass correlation coefficient, ICC>75) for total PA (ICC=0.79, 95% CI 0.65 to 0.82), occupational PA (ICC=0.77, 95% CI 0.68 to 0.82), active transportation (ICC=0.82, 95% CI 0.75 to 0.87) and vigorous intensity activities (ICC=0.82, 95% CI 0.76 to 0.87). Reliability was substantially higher for total PA (ICC=0.80), occupational PA (ICC=0.78), leisure-time PA (ICC=0.75) and active transportation (ICC=0.80) in men than in women, but domestic PA (ICC=0.38) and sitting time (ICC=0.71) demonstrated more substantial reliability coefficients in women than in men. For the construct validity, domestic PA was significantly related mainly with SBP (r=-0.27) and DBP (r=-0.17), and leisure-time PA and total PA were significantly related only with SBP (r=-0.16) and BMI (r=-0.29), respectively. Similarly, moderate-intensity PA was mainly related with SBP (r=-0.16, p<0.05) and DBP (r=-0.21, p<0.01), but vigorous-intensity PA was only related with BMI (r=-0.11, p<0.05). The modified Hausa IPAQ-LF demonstrated

Evaluating Validity Evidence for USMLE Step 2 Clinical Skills Data Gathering and Data Interpretation Scores: Does Performance Predict History-Taking and Physical Examination Ratings for First-Year Internal Medicine Residents?
Cuddy, Monica M; Winward, Marcia L; Johnston, Mary M; Lipner, Rebecca S; Clauser, Brian E
To add to the small body of validity research addressing whether scores from performance assessments of clinical skills are related to performance in supervised patient settings, the authors examined relationships between United States Medical Licensing Examination (USMLE) Step 2 Clinical Skills (CS) data gathering and data interpretation scores and subsequent performance in history taking and physical examination in internal medicine residency training. The sample included 6,306 examinees from 238 internal medicine residency programs who completed Step 2 CS for the first time in 2005 and whose performance ratings from their first year of residency training were available. Hierarchical linear modeling techniques were used to examine the relationships among Step 2 CS data gathering and data interpretation scores and history-taking and physical examination ratings. Step 2 CS data interpretation scores were positively related to both history-taking and physical examination ratings. Step 2 CS data gathering scores were not related to either history-taking or physical examination ratings after other USMLE scores were taken into account. Step 2 CS data interpretation scores provide useful information for predicting subsequent performance in history taking and physical examination in supervised practice and thus provide validity evidence for their intended use as an indication of readiness to enter supervised practice. The results show that there is less evidence to support the usefulness of Step 2 CS data gathering scores. This study provides important information for practitioners interested in Step 2 CS specifically or in performance assessments of medical students' clinical skills more generally.

The extent of international research on the Research Consortium's program between 1965 and 2008 was documented. A total of 9,132 abstracts were reviewed, and 657 (7.19%) had an international component. Inclusion of international research ranged from a low of 1.97% in 1983 to a high of 14.24% in 2007. There was a decrease in the amount of international research presented between 1965 and 1983, after which there was an increase through 2008. Most growth was from increased contributions coming from researchers in Southeast Asia. In terms of general research topics, eight areas increased over the 44-year history reviewed, and five areas decreased. Seven recommendations are advanced for expanding the place and role of international research within the Research Consortium.

Considerable work has been performed on NiAl over the last three decades, with an extremely rapid growth in research on this intermetallic occurring in the last few years due to recent interest in this material for electronic and high temperature structural applications. However, many physical properties and the controlling fracture and deformation mechanisms over certain temperature regimes are still in question. Part of this problem lies in the incomplete characterization of many of the alloys previously investigated. Fragmentary data on processing conditions, chemistry, microstructure and the apparent difficulty in accurately measuring composition has made direct comparison between individual studies sometimes tenuous. Therefore, the purpose of this review is to summarize all available mechanical and pertinent physical properties on NiAl, stressing the most recent investigations, in an attempt to understand the behavior of NiAl and its alloys over a broad temperature range.

The climate impact of ice-nucleating particles (INPs) derived from fertile soils on global scale has been recently accented by their diversity and efficient freezing ability. However, their representation in atmospheric models is limited in part due to our incomplete knowledge of fertile soil composition, abundance and associated sensitivity to heterogeneous ice nucleation. To fill given knowledge gap, we have investigated a unique/rich set of ice crystal residual samples derived from a variety of fertile soil samples obtained through our participation in the Fifth International Ice Nucleation workshop (FIN-1). FIN-1 was held at the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) facility at Karlsruhe Institute of Technology (KIT), which is the world's foremost facility for studying ice clouds in a controlled setting, in November 2014 to comprehensively study the heterogeneous ice formation in the atmosphere with collaboration among 10 international groups that were funded through European consortium, NSF and USDOE agencies. Here, we will present the nanoscale surface morphology and elemental/molecular composition of ice crystal residuals as well as that of total aerosol samples from the FIN-1 activity to identify and classify any specific mineral and organic inclusions that may have promoted nucleation of ice. Comparing total aerosols to residuals will shed light on the composition and abundance of certain particle types in INPs. Acknowledgements: The valuable contributions of the INUIT (Ice Nuclei Research Unit) collaborators, the FIN organizers, their institutions and the FIN-1 Workshop science team are gratefully acknowledged.
Advice on lifestyle changes (diet, red wine and physical activity) does not affect internal carotid and middle cerebral artery blood flow velocity in patients with carotid arteriosclerosis in a randomized controlled trial.

A Mediterranean diet, with and without small daily amounts of red wine, and physical activity reduce the risk of cerebrovascular disease and improve cognition. An increase in cerebral blood flow may be the underlying mechanism. Under normal conditions, cerebral blood flow velocity changes in the internal carotid arteries and in large basal cerebral arteries correlate closely with cerebral blood flow changes, as the diameter of these vessels hardly changes and only the smaller vessels downstream change their diameter. A prospective randomized controlled trial was performed in 108 patients with carotid atherosclerosis (mean age 64 years, 67% men, 66% on statin therapy). Half of them were advised to follow a polyphenol-rich modified Mediterranean diet including 1-2 tomatoes, 3-5 walnuts and a bar of dark chocolate (25 g) a day and to perform moderate physical exercise for 30 min/day (lifestyle changes). Within these two groups, half of the patients were randomized either to avoid any alcohol or to drink 100 ml of red wine (women) or 200 ml of red wine (men) daily. Bilateral middle cerebral and internal carotid blood flow velocity (peak systolic, peak end-diastolic and mean) was measured at baseline and after 4 and 20 weeks using colour-coded duplex ultrasound. Insonation depth and insonation angle were used to identically place the sample volume during follow-up investigations. A general linear model with Tukey-Kramer adjustment for multiple comparisons was used to assess the primary end points. For the analysis we used the mean values of the right and left artery. Neither lifestyle changes nor red wine had an effect on peak systolic, peak end-diastolic or mean cerebral blood flow velocity. Advice on lifestyle changes, including a modified polyphenol-rich Mediterranean diet, a glass of red wine daily and physical exercise, did not affect middle cerebral and internal carotid blood flow velocity in our patient group with carotid atherosclerosis. An increase in cerebral

The present work aims to gain insights into the role of peptide-lipid interactions in the mechanisms of cellular internalization and endosomal escape of the S4(13)-PV cell-penetrating peptide, which has been successfully used in our laboratory as a nucleic acid delivery system. A S4(13)-PV analogue, S4(13)-PVscr, displaying a scrambled amino acid sequence, deficient cell internalization and drug delivery inability, was used in this study for comparative purposes. Differential scanning calorimetry, fluorescence polarization and X-ray diffraction at small and wide angles techniques showed that both peptides interacted with anionic membranes composed of phosphatidylglycerol or a mixture of this lipid with phosphatidylethanolamine, increasing the lipid order, shifting the phase transition to higher temperatures and raising the correlation length between the bilayers. However, S4(13)-PVscr, in contrast to the wild-type peptide, did not promote lipid domain segregation and induced the formation of an inverted hexagonal lipid phase instead of a cubic phase in the lipid systems assayed. Electron microscopy showed that, as opposed to S4(13)-PVscr, the wild-type peptide induced the formation of a non-lamellar organization in membranes of HeLa cells. We concluded that lateral phase separation and destabilization of membrane lamellar structure without compromising membrane integrity are on the basis of the lipid-driven and receptor-independent mechanism of cell entry of S4(13)-PV peptide. Overall, our results can contribute to a better understanding of the role of peptide-lipid interactions in the mechanisms of cell-penetrating peptide membrane translocation, helping in the future design of more efficient cell-penetrating peptide-based drug delivery systems.

Practice, science and governance in interaction: European effort for the system-wide implementation of the International Classification of Functioning, Disability and Health (ICF) in Physical and Rehabilitation Medicine.
Stucki, Gerold; Zampolini, Mauro; Juocevicius, Alvydas; Negrini, Stefano; Christodoulou, Nicolas
Since its launch in 2001, relevant international, regional and national PRM bodies have aimed to implement the International Classification of Functioning, Disability and Health (ICF) in Physical and Rehabilitation Medicine (PRM), whereby contributing to the development of suitable practical tools. These tools are available for implementing the ICF in day-to-day clinical practice, standardized reporting of functioning outcomes in quality management and research, and guiding evidence-informed policy. Educational efforts have reinforced PRM physicians' and other rehabilitation professionals' ICF knowledge, and numerous implementation projects have explored how the ICF is applied in clinical practice, research and policy. Largely lacking though is the system-wide implementation of ICF in day-to-day practice across all rehabilitation services of national health systems. In Europe, system-wide implementation of ICF requires the interaction between practice, science and governance. Considering its mandate, the UEMS PRM Section and Board have decided to lead a European effort towards system-wide ICF implementation in PRM, rehabilitation and health care at large, in interaction with governments, non-governmental actors and the private sector, and aligned with ISPRM's collaboration plan with WHO. In this paper we present the current PRM internal and external policy agenda towards system-wide ICF implementation and the corresponding implementation action plan, while highlighting priority action steps - promotion of ICF-based standardized reporting in national quality management and assurance programs, development of unambiguous rehabilitation service descriptions using the International Classification System for Service Organization in Health-related Rehabilitation, development of Clinical Assessment Schedules, qualitative linkage and quantitative mapping of data to the ICF, and the cultural adaptation of the ICF Clinical Data Collection Tool in European languages.

X-ray micro-computed tomography (XMCT) was used in conjunction with confocal Raman mapping to measure the intra-granular pore size, binder volumes and to provide spatial and chemical maps of internal granular components in α-lactose monohydrate granules formulated with different molecular weights of polyvinyl pyrrolidone (PVP). Infrared spectroscopy was used to understand the molecular association of binder domains. Granules were prepared by high-shear aqueous granulation from α-lactose monohydrate and PVP K29/32 or K90. XMCT was used to visualise the granule microstructure, intra-granular binder distribution and measure intra-granular porosity, which was subsequently related to intrusion porosimetry measurements. Confocal Raman microscopy and infrared microscopy were employed to investigate the distribution of components within the granule and explore the nature of binder substrate interactions. XMCT data sets of internal granule microstructure provided values of residual porosity in the lactose:PVP K29/32 and lactose:PVP K90 granules of 32.41 ± 4.60% and 22.40 ± 0.03%, respectively. The binder volumes of the lactose:PVP K29/32 and lactose:PVP K90 granules were 2.98 ± 0.10% and 3.38 ± 0.07%, respectively, and were attributed to PVP-rich binder domains within the granule. Confocal Raman microscopy revealed anisotropic domains of PVP between 2 μm and 20 μm in size surrounded by larger particles of lactose, in both granule types. Raman data showed that PVP domains contained various amounts of lactose, whilst IR microscopy determined that the PVP was molecularly associated with lactose, rather than residual water. The work shows that XMCT can be applied to investigate granular microstructure and resolve the porosity and the excipient and binder volumes. Combining this technique with vibrational techniques provides further structural information and aids the interpretations of the XMCT images. When used complementarily, these techniques highlighted that

Purpose: MRI has become an attractive tool for tumor motion management. Current MR-compatible phantoms are only capable of reproducing translational motion. This study describes the construction and validation of a more realistic, MRI-compatible lung phantom that is deformable internally as well as externally. We demonstrate a radiotherapy application of this phantom by validating the geometric accuracy of the open-source deformable image registration software NiftyReg (UCL, UK). Methods: The outer shell of a commercially-available dynamic breathing torso phantom was filled with natural latex foam with eleven water tubes. A rigid foam cut-out served as the diaphragm. A high-precision programmable, in-house, MRI-compatiblemore » motion platform was used to drive the diaphragm. The phantom was imaged on a 3T scanner (Philips, Ingenia). Twenty seven tumor traces previously recorded from lung cancer patients were programmed into the phantom and 2D+t image sequences were acquired using a sparse-sampling sequence k-t BLAST (accn=3, resolution=0.66×0.66×5mm3; acquisition-time=110ms/slice). The geometric fidelity of the MRI-derived trajectories was validated against those obtained via fluoroscopy using the on board kV imager on a Truebeam linac. NiftyReg was used to perform frame by frame deformable image registration. The location of each marker predicted by using NiftyReg was compared with the values calculated by intensity-based segmentation on each frame. Results: In all cases, MR trajectories were within 1 mm of corresponding fluoroscopy trajectories. RMSE between centroid positions obtained from segmentation with those obtained by NiftyReg varies from 0.1 to 0.21 mm in the SI direction and 0.08 to 0.13 mm in the LR direction showing the high accuracy of deformable registration. Conclusion: We have successfully designed and demonstrated a phantom that can accurately reproduce deformable motion under a variety of imaging modalities including MRI, CT and x

Social scientists have long worked to replicate real-world phenomena in their research and teaching environments. Unlike our biophysical science colleagues, we are faced with an area of study that is not governed by the laws of physics and other more predictable relationships. As a result, social scientists, and international studies scholars more…
Physicists traditionally get employed by academia, National Labs and industry. The investment of multi-national companies in R&D and manufacturing operations globally has been accelerating owing to availability of trained human resources and the economy of operation. This has created tremendous opportunities for candidates with global experience as opposed to a highly localized education. In the last decade, the investments made by Asian academic institutions in education and research has seen a significant increase creating opportunities for Graduate students and researchers alike in parts of the world other than US and Europe, the traditional destinations for students and researchers over the last several decades. Many Asian universities are hiring a diverse faculty from all over the world as opposed to hiring from local talent pools. Many of the Asian countries are focusing on creating local hitech economies by fostering global entrepreneurship programs. In my talk I will discuss this globalization phenomenon with specific examples from both academia and industry. I will also discuss strategies for academic institutions in terms of making the appropriate modification to their programs to deal with this inevitable evolution.

The Geotail spacecraft will be provided by the Institute of Space and Astronautical Science (ISAS) and will provide a Delta Launch Vehicle, tracking support by the Deep Space Network (DSN), and data processing support by GSFC. In exchange, ISAS will reserve part of the payload for NASA instruments together with a certain number of investigators from the United States. As the solar wind flows toward the Earth, some of the energy is modified by the Earth's magnetosphere, ionosphere, and upper atmosphere. This interaction causes the flow to be altered, creating a plasmasphere, plasma sheet, and ring currents in the Earth's Geomagnetic Tail region. The result is a series of distinct regions which affect processes on the Earth. By traversing the tail region to a variety of depths, Geotail will be able to determine the size, position, and other properties of these regions. When correlated with information obtained from the other ISAS spacecraft, Geotail data should help to provide a more complete understanding of how the solar processes affect the Earth's environment. The flight profile is given, and information is presented in tabular form on the following topics: DSN support, frequency assignments, telemetry, command, and tracking support responsibility.

Large regional differences remain in the number of girls studying physics and the number of female physicists in academic positions. While many countries struggle with attracting female students to university studies in physics, climbing the academic ladder is the main challenge for these women. Furthermore, for many female physicists the working climate is not very supportive. The workshop Attracting Girls to Physics, organized as part of the 4th IUPAP International Conference on Women in Physics, South Africa 2011, addressed attitudes among education-seeking teenagers and approaches for attracting young girls to physics through successful recruitment plans, including highlighting the broad spectrum of career opportunities for those with physics qualifications. The current paper presents findings, examples of best practices, and recommendations resulting from this workshop.

The 1996 Centennial Olympic Games in Atlanta, Georgia, received weather support from the National Weather Service (NWS). The mandate to provide this support gave the NWS an unprecedented opportunity to employ in an operational setting several tools and practices similar to those planned for the "modernized" era of the NWS. The project also provided a glimpse of technology and practices not planned for the NWS modernization, but that might be valuable in the future. The underlying purpose of the project was to protect the life and property of the two million spectators, athletes, volunteers, and officials visiting and/or participating in the games. While there is no way to accurately account for lives and property that were protected by the NWS support, the absence of weather-related deaths, significant injuries, and damaged property during the games despite an almost daily occurrence of thunderstorms, high temperatures, and/or rain indicates that the project was a success. In fact, popular perception held that weather had no effect on the games. The 2000+ weather bulletins issued during the 6-week support period suggest otherwise. The authors describe the many facets of this demanding and successful project, with special attention given to aspects related to operational forecasting. A postproject survey completed by the Olympics forecasters, feedback provided by weather support customers, and experiences of the management team provide the bases for project observations and recommendations for future operational forecasting activities.

Still photographs taken over 16 hours on Nov. 13, 2001, on the International Space Station have been condensed into a few seconds to show the de-mixing -- or phase separation -- process studied by the Experiment on Physics of Colloids in Space. Commanded from the ground, dozens of similar tests have been conducted since the experiment arrived on ISS in 2000. The sample is a mix of polymethylmethacrylate (PMMA or acrylic) colloids, polystyrene polymers and solvents. The circular area is 2 cm (0.8 in.) in diameter. The phase separation process occurs spontaneously after the sample is mechanically mixed. The evolving lighter regions are rich in colloid and have the structure of a liquid. The dark regions are poor in colloids and have the structure of a gas. This behavior carnot be observed on Earth because gravity causes the particles to fall out of solution faster than the phase separation can occur. While similar to a gas-liquid phase transition, the growth rate observed in this test is different from any atomic gas-liquid or liquid-liquid phase transition ever measured experimentally. Ultimately, the sample separates into colloid-poor and colloid-rich areas, just as oil and vinegar separate. The fundamental science of de-mixing in this colloid-polymer sample is the same found in the annealing of metal alloys and plastic polymer blends. Improving the understanding of this process may lead to improving processing of these materials on Earth.

A significant portion of radiation treatment (30-40%) is delivered with palliative intent. Given the frequency of palliative care (PC) in radiation oncology, we determined the patterns of research focusing on symptom control and palliative care (SCPC) in two prominent radiation oncology journals from 2005-2014. Original research manuscripts published from 2005-2014 in the International Journal of Radiation Oncology *Biology* Physics (Red Journal) and the Radiotherapy and Oncology Journal (Green Journal) were reviewed to categorize articles as PC and/or SCPC. Articles were categorized as PC if it pertained to any aspect of treatment of metastatic cancer, and as SCPC if symptom control in the metastatic cancer setting was the goal of the research inquiry and/or any domain of palliative clinical practice guidelines was the goal of research inquiry. From 2005-2014, 4.9% (312/6,386) of original research articles published in the Red Journal and 3.5% (84/2,406) published in the Green Journal pertained to metastatic cancer, and were categorized as PC. In the Red Journal, 1.3% (84/6,386) of original research articles were categorized as SCPC; 1.3% (32/2,406) of articles in the Green Journal were categorized as SCPC. There was no trend observed in the proportion of SCPC articles published over time in the Red Journal (P=0.76), the Green Journal (P=0.48), or both journals in aggregate (P=0.38). Despite the fact that palliative radiotherapy is a critical part of radiation oncology practice, PC and SCPC-focused original research is poorly represented in the Red Journal and the Green Journal.

The purpose of this three study dissertation is to investigate why students are enrolled in introductory physics courses experience difficulties in being successful; one possible source of their difficulties is related to their epistemology. In order to investigate students' epistemologies about mathematics and physics, students were observed solving physics problems in groups during a laboratory course (study 1) and while solving physics and mathematics problems individually during office-hour sessions (study 2). The Epistemological Resources theoretical framework was employed (Hammer & Elby, 2002). Using emergent and a priori epistemological resource operationalizations (Jones, 2015), 25 distinct epistemological resources were identified in study 1. Differences in physics epistemological resource usage between students of varying academic background (as measured by their number of previously completed mathematics and science classes were identified. By employing an external (Jones, 2015) and internal (Scanlon, 2016) a priori epistemological resource coding scheme, a total of 17 distinct epistemological resources were identified in study 2. The data were sampled to compare the mathematics and physics epistemological resource usage of participants with consistent and inconsistent sign usage in an energy conservation physics problem in order to provide a meaningful context for discussion. Participants of the same sign usage group employed epistemological resources similarly. Conversely, participants in different groups had significantly different physics epistemological resource usage patterns. Finally, student epistemological resource usage patterns from the first two studies were compared to course outcomes in order to determine implications for practice (study 3). Educators must be aware of and address the epistemological underpinnings of students' difficulties in introductory physics courses.

The aims, organizational plan and syllabus of a specialized Astronomy School with a subject of training students for participation in the International Astronomy Olympiad, are presented. Thematic frame includes basic educational activities during the preparation and self-preparation of the students and their participation in astronomical Olympiads. A model of identification and selection of outstanding students for astronomical Olympiads has been developed. Examples of didactic systems of problems for development of mathematical, physical and astronomical skills are shown. The programme ends with individual training for solving problems on astronomy and astrophysics. Possibilities, which the characteristic, non-standard astronomical problems give for stimulating the creative and original thinking, are specified. Basic psychological condition for development of the students' creative potential - transformation of the cognitive content in emotional one - is demonstrated. The programme of identification and support of outstanding students on astronomy is realized in collaboration with The Ministry of Education and Science, Public Astronomical Observatories and Planetaria, Institute of Astronomy - Bulgarian Academy of Sciences, and The Union of Astronomers in Bulgaria.
