Pollutants emitted during motor vehicle cold starts, especially in winter in some climates, is a significant source of winter time air pollution. While data exist for CO, NO, and total hydrocarbon emissions from federal testing procedures for vehicle emission certification, little is known about the emission rates of individual volatile organic compounds, in particular the air toxics benzene, formaldehyde, and acetaldehyde. Little is known about the VOC speciation and temperature dependence for cold starts. The US EPA vehicle emission model MOVES assumes that cold start emissions have the same speciation profile as running emissions. We examined this assumption by measuring cold start exhaust composition for 4 vehicles fueled with E10 gasoline over a temperature range of -4°C to 10°C in winter of 2015. The extra cold start emissions were determined by comparison with emissions during engine idling. In addition to CO and NOx measurements a proton transfer reaction mass spectrometer was used to measure formaldehyde, acetaldehyde, benzene, toluene, and C2-alkylbenzenes at high time resolution to compare with the cold start emission speciation profiles used in the EPA MOVES2014 model. The results show that after the vehicle was started, CO mixing ratios can reach a few percent of the exhaust and then drop to several ppmv within 2 minutes of idling, while NOx showed different temporal behaviors among the four vehicles. VOCs displayed elevated levels during cold start and the peak mixing ratios can be two orders higher than idling phase levels. Molar emission ratios relative to toluene were used to compare with the emission ratio used in MOVES2014 and we found the formaldehyde-to-toluene emission ratio was about 0.19, which is 5 times higher than the emission ratio used in MOVES2014 and the acetaldehyde-to-toluene emission ratios were 0.86-0.89, which is 8 times higher than the ones in MOVES2014. The C2-alkylbenzene-to-toluene ratio agreed well with moves. Our results suggest that for the air toxics acetaldehyde and formaldehyde, wintertime cold temperature vehicle start emissions are likely significantly underestimated in the MOVES 2014 model.

Bong-Guk Kim1, Yang-Ki Cho1, Sangil Kim2, Kwang-Yul, Kim1 1 School of Earth and Environmental Sciences, College of Natural Sciences, Seoul National University, Seoul, South Korea 2 College of Oceanic and Atmospheric Sciences, Oregon State University, Corvallis, Oregon, USA To understand the ocean carbon cycle, estimating the ocean biomass is necessary and it has been done by various methods. Satellite observation is one of beneficial methods to investigate ocean biomass. Satellite data enable us to monitor chlorophyll-a for wide area with high resolution and frequency. The East/Japan Sea, which called as 'miniature ocean' due to its rapid turnover circulation, is one of the most productive ocean. With the concerning global warming, a number of studies on temporal and spatial distribution of satellite chlorophyll in the East/Japan Sea have been processed. However, most of these studies have used monthly data set which can not resolve detail evolution of chlorophyll-a. In this study, detail evolutions of spring and fall bloom are investigated by the CSEOF (Cyclo-Stationary EOF) analysis of 8-day composite MODIS chlorophyll data from July 2002 to February 2012. For the CSEOF analysis, optimal interpolation (OI) method was applied to fill the blank data which is critical problem in satellite data. Spring bloom started at western Japanese coast on 57th day of the year. And it gradually moves eastern coast of Korean and then moves to northern Primorye coast. Spring bloom spreads entire the East/Japan Sea on 113th day of the year and then, it disappears from the southern East/Japan Sea. Spring bloom ends in the northern East/Japan Sea. In the case of fall bloom, it starts at Korean coast on 265th day of the year, and it moves to the north along the Korean coast by 329th day of the year. After that day, fall bloom ends near the northern coast of Korea on 353rd day of the year.

Defining and Developing "Critical Thinking" Through Devising and Testing Multiple Explanations of the Same Phenomenon

Most physics teachers would agree that one of the main reasons for her/his students to take physics is to learn to think critically. However, for years we have been assessing our students mostly on the knowledge of physics content (conceptually and quantitatively). Only recently have science educators started moving systematically towards achieving and assessing this critical thinking goal. In this paper we seek to show how guiding students to devise and test multiple explanations of observed phenomena can be used to improve their critical thinking.

Eliciting, Identifying, Interpreting, and Responding to Students' Ideas: Teacher Candidates' Growth in Formative Assessment Practices

With the goal of helping teacher candidates become well-started beginners, it is important that methods courses in teacher education programs focus on high-leverage practices. Using responsive teaching practices, specifically eliciting, identifying, interpreting, and responding to students' science ideas (i.e., formative assessment), can be used to support all students in learning science successfully. This study follows seven secondary science teacher candidates in a yearlong practice-based methods course. Course assignments (i.e., plans for and reflections on teaching) as well as teaching videos were analyzed using a recursive qualitative approach. In this paper, we present themes and patterns in teacher candidates' abilities to elicit, identify, interpret, and respond to students' ideas. Specifically, we found that those teacher candidates who grew in the ways in which they elicited students' ideas from fall to spring were also those who were able to adopt a more balanced reflection approach (considering both teacher and student moves). However, we found that even the teacher candidates who grew in these practices did not move toward seeing students' ideas as nuanced; rather, they saw students' ideas in a dichotomous fashion: right or wrong. We discuss implications for teacher preparation, specifically for how to promote productive reflection and tools for better understanding students' ideas.

Science, state, and spirituality: Stories of four creationists in South Korea.

PubMed

Park, Hyung Wook; Cho, Kyuhoon

2018-03-01

This paper presents an analysis of the birth and growth of scientific creationism in South Korea by focusing on the lives of four major contributors. After creationism arrived in Korea in 1980 through the global campaign of leading American creationists, including Henry Morris and Duane Gish, it steadily grew in the country, reflecting its historical and social conditions, and especially its developmental state with its structured mode of managing science and appropriating religion. We argue that while South Korea's creationism started with the state-centered conservative Christianity under the government that also vigilantly managed scientists, it subsequently constituted some technical experts' efforts to move away from the state and its religion and science through their negotiation of a new identity as Christian intellectuals ( chisigin). Our historical study will thus explain why South Korea became what Ronald Numbers has called "the creationist capital of the world."

A journey with Fred Hoyle. The search for cosmic life

2005-01-01

This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle-Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science - the theory that life originated on Earth in a warm primordial soup.

Clewell, Beatriz Chu; Campbell, Patricia B.

Focusing on “where we’ve been, where we are, and where we’re going,” the authors examine minority women’s and White women’s progress in science, mathematics, engineering, and technology (SMET) over the past decade. Starting from an exploration of participation and achievement data, the authors move on to cover the theories behind SMET gender differences, including those based on testing, biology, social-psychology, and cognitive sciences. Looking at practice as well as theory, the authors explore the impacts that interventions and contextual influences, such as societal change and education reform, have had on efforts to achieve gender parity in SMET. The article concludes with the recommendation of logical next steps to preserve and expand the gains made by women in these fields.

The NSF-funded EarthCube Integration and Test Environment (ECITE) prototype was proposed as a 2015 Integrated Activities project and resulted in the prototyping of an EarthCube federated cloud environment and the Integration and Testing Framework. The ECITE team has worked with EarthCube science and technology governance committees to define the types of integration, testing and evaluation necessary to achieve and demonstrate interoperability and functionality that benefit and support the objectives of the EarthCube cyber-infrastructure. The scope of ECITE also includes reaching beyond NSF and EarthCube to work with the broader Earth science community, such as the Earth Science Information Partners (ESIP) to incorporate lessons learned from other testbed activities, and ultimately provide broader community benefits. This presentation will discuss evolving ECITE ideas for a science-driven workbench that will start with documented science use cases, map the use cases to solution scenarios that identify the available technology and data resources that match the use case, the generation of solution workflows and test plans, the testing and evaluation of the solutions in a cloud environment, and finally the documentation of identified technology and data gaps that will assist with driving the development of additional EarthCube resources.

Bringing science to business

NASA Astrophysics Data System (ADS)

Lemetti, Paul

2005-06-01

Bringing science to business seems rather straight forward. Technology is constantly moving forward and new inventions are being brought into the market place. Science parks and technology parks have sprung out all around the globe competing against each other and trying to keep their own doors open by bringing in new business, thereby creating much needed income to keep their operations moving forward. However, only a small handful ofthese centers around the world can truly be considered successful. It is the relationship between the scientists, start-up business, local universities, local government, and invited bigger business that allows the parks to succeed. The individual scientist wishing to enter into business or just hoping to get his invention into the pool of potential ideas; which might end up in the hands of an entrepreneur or an established company, is not always that simple. Universal success principles must be embraced to ensure success. One must believe in oneself and to strive for excellence. One must be able to see the other persons viewpoint and adapt and change his behavior in order to succeed. One must learn to create trust as well as learn to trust. Furthermore, one must learn to focus on the why of the process and not on the how. A market must be identified and benefits of local area must be sold to potential investor or business partners. A local success has in part to do with local cooperation.

Positioning positivism, critical realism and social constructionism in the health sciences: a philosophical orientation.

PubMed

Cruickshank, Justin

2012-03-01

Positioning positivism, critical realism and social constructionism in the health sciences: a philosophical orientation This article starts by considering the differences within the positivist tradition and then it moves on to compare two of the most prominent schools of postpositivism, namely critical realism and social constructionism. Critical realists hold, with positivism, that knowledge should be positively applied, but reject the positivist method for doing this, arguing that causal explanations have to be based not on empirical regularities but on references to unobservable structures. Social constructionists take a different approach to postpositivism and endorse a relativist rejection of truth and hold that the task of research is to foster a scepticism that undermines any positive truth claim made. It is argued that social constructionism is a contradictory position. © 2011 Blackwell Publishing Ltd.

In life and work, Claudio Bunster prefers extreme challenges. Bunster, a physicist who contemplates brain-warping theories of space and time, returned to his native Chile from the United States precisely when most intellectuals would have stayed clear - during the middle of the Pinochet dictatorship. Shut out of the universities by the military government, he broke the conventional mold by founding a research institute that he then moved from Santiago, the capital, to Valdivia in southern Chile, against the flow of minds and money. He led the presidential science advisory committee during the administration of Eduardo Frei, and served on the Dialogue Board of Human Rights to reconcile Chilean military and civil society. For his achievements, Bunster was elected to the National Academy of Sciences in 2005. In his Inaugural Article, which appeared in the July 24, 2007 issue of PNAS [1], he showed that after a black hole swallows a magnetic monopole, the space-time singularity starts rotating.

Commercializing medical technology.

Scanlon, Kevin J; Lieberman, Mark A

As medicine moves into the 21st century, life saving therapies will move from inception into medical products faster if there is a better synergy between science and business. Medicine appears to have 50-year innovative cycles of education and scientific discoveries. In the 1880's, the chemical industry in Germany was faced with the dilemma of modernization to exploit the new scientific discoveries. The solution was the spawning of novel technical colleges for training in these new chemical industries. The impact of those new employees and their groundbreaking compounds had a profound influence on medicine and medical education in Germany between 1880 and 1930. Germany dominated international science during this period and was a training center for scientists worldwide. This model of synergy between education and business was envied and admired in Europe, Asia and America. British science soon after evolved to dominate the field of science during the prewar and post World War (1930's-1970's) because the German scientists fled Hitler's government. These expatriated scientists had a profound influence on the teaching and training of British scientists, which lead to advances in medicine such as antibiotics. After the Second World War, the US government wisely funded the development of the medical infrastructure that we see today. British and German scientists in medicine moved to America because of this bountiful funding for their research. These expatriated scientists helped drive these medical advances into commercialized products by the 1980's. America has been the center of medical education and advances of biotechnology but will it continue? International scientists trained in America have started to return to Europe and Asia. These American-trained scientists and their governments are very aware of the commercial potential of biotechnology. Those governments are now more prepared to play an active role this new science. Germany, Ireland, Britain, Singapore, Taiwan and Israel are such examples of this government support for biotechnology in the 21st century. Will the US continue to maintain its domination of biotechnology in this century? Will the US education system adjust to the new dynamic of synergistic relationships between the education system, industry and government? This article will try to address these questions but also will help the reader understand who will emerge by 2015 as the leader in science and education.

In recent years, librarians in various sectors have been moving forward a conversation on the distinct information needs and information-seeking behavior of our lesbian, gay, bisexual, trans, and queer (LGBTQ) patrons and how well the profession recognizes and meets those needs. Health sciences librarianship has been slower than other areas of the profession in creating an evidence base covering the needs of its LGBTQ patrons, with, until recently, only very limited literature on this subject. LGBTQ health sciences librarianship is now starting to attract new interest, with librarians working together to bring this emerging specialization to the attention of the broader professional community. In this paper, the authors report on a dedicated panel discussion that took place at the 2016 joint annual meeting of the Medical Library Association and Canadian Health Libraries Association/Association des bibliothèques de la santé du Canada in Toronto, Ontario, Canada; discuss subsequent reflections; and highlight the emerging role for health sciences librarians in providing culturally competent services to the LGBTQ population. Recommendations are also provided for establishing a tool kit for LGBTQ health sciences librarianship from which librarians can draw.

The geoscience research and education community is interested in developing scalable and effective user-friendly strategies for reaching the public, students and educators with information about the Earth and space sciences. Based on experience developed over the past decade with education and outreach programs seeking to reach these populations, there is a growing consensus that this will be best achieved through collaboration, leveraging the resources and networks already in existence. While it is clear that gifted researchers and developers can create wonderful online educational resources, many programs have been stymied by the difficulty of attracting an audience to these resources. The National Earth Science Teachers Association (NESTA) has undertaken an exciting new project, with support from the William and Flora Hewlett Foundation, that provides a new platform for the geoscience education and research community to share their research, resources, programs, products and services with a wider audience. In April 2010, the Windows to the Universe project (http://windows2universe.org) moved from the University Corporation for Atmospheric Research to NESTA. Windows to the Universe, which started in 1995 at the University of Michigan, is one of the most popular Earth and space science education websites globally, with over 16 million visits annually. The objective of this move is to develop a suite of new opportunities and capabilities on the website that will allow it become a sustainable education and outreach platform for the geoscience research and education community hosting open educational resources. This presentation will provide an update on our progress, highlighting our new strategies, synergies with community needs, and opportunities for collaboration.

Charlotte Moore Sitterly: A Life of Spectroscopy

NASA Astrophysics Data System (ADS)

Rubin, Vera C.

2010-01-01

Dr. Charlotte Moore Sitterly was a scientist in an era when it was rare for a woman to have the opportunity to devote her life to forefront science. Following her graduation from Swarthmore College in 1920, she accepted a position at Princeton University as an assistant to Henry Norris Russell. In 1925 she started a study of the solar spectrum. She could then not know that she would devote much of her scientific career to gathering basic atomic data that are invaluable to the scientific community, even today. In 1931 she obtained a PhD degree at U. California, Berkeley, and returned to Princeton as a staff member of the Princeton University Observatory. In 1945 she moved to the National Bureau of Science (NBS), to supervise preparation of the widely used tables of atomic energy levels. Following the successful lunching (1946) of a V2 rocket to obtain the ultra violet spectrum of the sun, Moore started working with Richard Tousey and his group at the Naval Research Laboratory (NRL). Ultimately, they extended the solar spectrum down to 2200 angstroms. She continued her affiliations with NBS and NRL until her death in 1990. Charlotte Moore was rare scientist who devoted her career to obtaining accurate numbers, thus enabling the scientific community to open her tables and know that the data are accurate.

Trends in Soil Science education: moving from teacher's questioning to student's questioning

NASA Astrophysics Data System (ADS)

Roca, Núria

2017-04-01

Soil science has suffered from communication problems within its own discipline, with other disciplines (except perhaps agronomy) and with the general public. Prof. Dennis Greenland wrote the following in the early 1990s: "…soil scientists have also been frustrated as their advice has gone apparently unheeded. This may be because the advice is couched in terms more easily understood by other soil scientists than by politicians and economists who control the disposition of land. If soil science is to serve society fully it is essential that its arguments are presented in terms readily understood by all and with both scientific and economic rigor so that they are not easily refuted". Soil is a 3-dimensional body with properties that reflect the impact of climate, vegetation, fauna, man and topography on the soil's parent material over a variable time span. Therefore, soil sciences must integrate different knowledge of many disciplines. How should one go about the teaching and learning of a subject like soil science? This is an ever present question resident in the mind of a soil science teacher who knows that students will find soil science an inherently difficult subject to understand. Therefore, Soil Science cannot be taught in the same way. This paper proposes a mural construction that allows to understand soil formation, soil evolution and soil distribution. This experience has been realized with secondary teachers to offer tools for active learning methodologies. Therefore, this teaching project starts with a box and a global soil map distribution in a wall mural. The box contains many cards with soil properties, soil factors, soil process, soils orders and different natural soil photos as the pieces of a big puzzle. All these pieces will be arranged in the wall mural. These environments imply a new perspective of teaching: moving from a teacher-centered teaching to a student-centered teaching. In contrast to learning-before-doing— the model of most educational settings. The main functions such as encouraging students to think, arousing interest and curiosity, developing students' reflection and stimulate students to ask questions of their own will be developed with the construction of the mural.

Reciprocity relations in aerodynamics

NASA Technical Reports Server (NTRS)

Heaslet, Max A; Spreiter, John R

1953-01-01

Reverse flow theorems in aerodynamics are shown to be based on the same general concepts involved in many reciprocity theorems in the physical sciences. Reciprocal theorems for both steady and unsteady motion are found as a logical consequence of this approach. No restrictions on wing plan form or flight Mach number are made beyond those required in linearized compressible-flow analysis. A number of examples are listed, including general integral theorems for lifting, rolling, and pitching wings and for wings in nonuniform downwash fields. Correspondence is also established between the buildup of circulation with time of a wing starting impulsively from rest and the buildup of lift of the same wing moving in the reverse direction into a sharp-edged gust.

Industrial Section Convenor's Report

Barone, M.; Riboni, P.

2002-11-01

Over the years this conference has gained a solid reputation as an appropriate rostrum for illustrating new concepts in the relations between industry and the scientific world and for introducing new technologies to a large assistance of junior and more experienced scientists. In fact, from the very beginning the founders of this endeavour announced: "The conference is aimed for promoting contacts among scientists involved in particle and fundamental physics, among experimental physicists in other fields and representatives from industry." Facilities at the Conference are designed to fulfil the task: space and general facilities are offered to industry representatives to display their products. This year a more accessible and luminous space arrangement was made available to the exhibitors. At the same time two plenary sessions have been dedicated to selected speakers to illustrate new trends in Technology Transfer, analysis of environment affecting our community, examples of historical successes in the merging of science and industry. We have identified in "GRID" and in "E-Publishing" two major promising areas where our Community will play a prime role as "User" and it was of the general interest to have them illustrated by two personalities directly involved in their development. The flow of knowledge is of course more massive from "Industry" to "Science" than vice-versa, but "Science" to "Industry" move offers an intensive added value. The technology transfer concept with the "Patents" as fund raising tool proved less glorious than expected. Trademark, licensing agreement and " Patents" can assure intellectual properties. But patent is an issue to be used cautiously. Evidence exists that much more efficient transfer of "Science" knowledge to "Economy" is achieved by venture capital move and start-up companies. These two facets of the Technology Transfer business have been covered by Routti's and Bourgeois's lectures.There are two examples of Companies who moved recently into the areas of interest of our community (Hourdakis and Intrasoft) and the examples of an Industry historically committed to a strong R&D effort (SAES-Getters). Finally a case of involvement of industry in a "Big Science" project (CMS) completed the palette of the contributions to this Industry Section. The full set of transparencies of the lectures, are filed and made available at the conference site: .

My laboratory investigations have been driven by an abiding interest in understanding the consequences of genetic rearrangement in evolution and disease, and in using viruses to elucidate fundamental mechanisms in biology. Starting with bacteriophages and moving to the retroviruses, my use of the tools of genetics, molecular biology, biochemistry, and biophysics has spanned more than half a century-from the time when DNA structure was just discovered to the present day of big data and epigenetics. Both riding and contributing to the successive waves of technology, my laboratory has elucidated fundamental mechanisms in DNA replication, repair, and recombination. We have made substantial contributions in the area of retroviral oncogenesis, delineated mechanisms that control retroviral gene expression, and elucidated critical details of the structure and function of the retroviral enzymes-reverse transcriptase, protease, and integrase-and have had the satisfaction of knowing that the fundamental knowledge gained from these studies contributed important groundwork for the eventual development of antiviral drugs to treat AIDS. While pursuing laboratory research as a principal investigator, I have also been a science administrator-moving from laboratory head to department chair and, finally, to institute director. In addition, I have undertaken a number of community service, science-related "extracurricular" activities during this time. Filling all of these roles, while being a wife and mother, has required family love and support, creative management, and, above all, personal flexibility-with not too much long-term planning. I hope that this description of my journey, with various roles, obstacles, and successes, will be both interesting and informative, especially to young female scientists.

Progression in Ethical Reasoning When Addressing Socio-scientific Issues in Biotechnology

NASA Astrophysics Data System (ADS)

Berne, Birgitta

2014-11-01

This article reports on the outcomes of an intervention in a Swedish school in which the author, a teacher-researcher, sought to develop students' (14-15 years old) ethical reasoning in science through the use of peer discussions about socio-scientific issues. Prior to the student discussions various prompts were used to highlight different aspects of the issues. In addition, students were given time to search for further information themselves. Analysis of students' written arguments, from the beginning of the intervention and afterwards, suggests that many students seem to be moving away from their use of everyday language towards using scientific concepts in their arguments. In addition, they moved from considering cloning and 'designer babies' solely in terms of the present to considering them in terms of the future. Furthermore, the students started to approach the issues in additional ways using not only consequentialism but also the approaches of virtue ethics, and rights and duties. Students' progression in ethical reasoning could be related to the characteristics of the interactions in peer discussions as students who critically and constructively argued with each other's ideas, and challenged each other's claims, made progress in more aspects of ethical reasoning than students merely using cumulative talk. As such, the work provides valuable indications for the importance of introducing peer discussions and debates about SSIs in connection to biotechnology into the teaching of science in schools.

Solid earth geophysicists have a long tradition of writing scientific software to address a wide range of problems. In particular, computer simulations came into wide use in geophysics during the decade after the plate tectonic revolution. Solution schemes and numerical algorithms that developed in other areas of science, most notably engineering, fluid mechanics, and physics, were adapted with considerable success to geophysics. This software has largely been the product of individual efforts and although this approach has proven successful, its strength for solving problems of interest is now starting to show its limitations as we try to share codes and algorithms or when we want to recombine codes in novel ways to produce new science. With funding from the NSF, the US community has embarked on a Computational Infrastructure for Geodynamics (CIG) that will develop, support, and disseminate community-accessible software for the greater geodynamics community from model developers to end-users. The software is being developed for problems involving mantle and core dynamics, crustal and earthquake dynamics, magma migration, seismology, and other related topics. With a high level of community participation, CIG is leveraging state-of-the-art scientific computing into a suite of open-source tools and codes. The infrastructure that we are now starting to develop will consist of: (a) a coordinated effort to develop reusable, well-documented and open-source geodynamics software; (b) the basic building blocks - an infrastructure layer - of software by which state-of-the-art modeling codes can be quickly assembled; (c) extension of existing software frameworks to interlink multiple codes and data through a superstructure layer; (d) strategic partnerships with the larger world of computational science and geoinformatics; and (e) specialized training and workshops for both the geodynamics and broader Earth science communities. The CIG initiative has already started to leverage and develop long-term strategic partnerships with open source development efforts within the larger thrusts of scientific computing and geoinformatics. These strategic partnerships are essential as the frontier has moved into multi-scale and multi-physics problems in which many investigators now want to use simulation software for data interpretation, data assimilation, and hypothesis testing.

The microgravity environment of the D1 mission

Hamacher, H.; Merbold, U.; Jilg, R.

1990-01-01

Some characteristic features and results of D1 microgravity measurements are discussed as performed in the Material Science Double Rack (MSDR) and the Materials Science Double Rack for Experiment Modules and Apparatus (MEDEA). Starting with a brief review of the main potential disturbances, the payload aspects of interest to the analysis and the accelerometer measuring systems are described. The microgravity data are analyzed with respect to selected mission events such as thruster firings for attitude control, operations of Spacelab experiment facilities, vestibular experiments and crew activities. The origins are divided into orbit, vehicle, and experiment induced perturbations. It has been found that the microgravity-environment is dictated mainly by payload-induced perturbations. To reduce the microgravity-level, the design of some experiment facilities has to be improved by minimizing the number of moving parts, decoupling of disturbing units from experiment facilities, by taking damping measures, etc. In addition, strongly disturbing experiments and very sensitive investigations should be performed in separate mission phases.

Philosophical aesthetics and cognitive science.

Philosophical aesthetics is the branch of philosophy which explores issues having to do with art, beauty, and related phenomena. Philosophers have often been skeptical about the place of empirical investigation in aesthetics. However, in recent years many philosophical aestheticians have turned to cognitive science to enrich their understanding of their subject matter. Cognitive scientists have, in turn, been inspired by work in philosophical aesthetics. This essay focuses on a representative subset of the areas in which there has been fruitful dialog between philosophical aestheticians and cognitive scientists. We start with some general topics in philosophical aesthetics-the definition of art and the epistemic status of aesthetic judgments. We then move on to discussing research concerning the roles that imagination and perception play in our aesthetic engagement. We conclude with a discussion of the emerging field of experimental philosophical aesthetics.

Numerical Simulation of Pre-heated Confined PBX Charge Under Low Velocity

NASA Astrophysics Data System (ADS)

Hu, Cai; Wu, Yanqing; Huang, Fenglei; Liu, Yan; Explosion; damage Team

2017-06-01

Impact sensitivity and thermal safety are very important for explosive safety usage.To investigate the effect of thermal softening on impact sensitivity of HMX-based PBX, a finite element model aiming at pre-heated confined PBX charge sbujected to bullets impact has been established. The predicted ignition starting area of the explosive charge was evaluated based on volume strain and equivalent strain contours. It showed that the ignition starting area moves towards the center of the explosives from the surface with increase of heating temperature. The threshold velocity does not increase monotonically with the pre-heating temperature increases. Instead, the threshold velocity rises till 360 m/s when the cook-off temperature is lower than 75°, then decreases the increased temperature. The results imply that our PBX has the lowest impact sensitivity at about 75°. These numerical results agree very well with the corresponding experiment results conducted by Dai et al. The influence of thermal softening on the impact sensitivity has been analyzed. As the strength decreases, more impact energy will be absorbed. At the same time, shear resistance ability will be weaken and volume compression work may play a more important role to ignition.

Pilgrim, David

2016-07-01

The relationship between the arts and health is now of interest to policy makers, patients, professionals and health researchers. This article historicises the potential for holism, a current aspiration within the medical humanities. This contemporary debate in the research community reflects philosophical positions about idealism and realism, with their traceable historical roots. This article summarises those roots and draws attention to their current relevance for health researchers. Starting with the recognition within the medical humanities that biomedical reductionism now attracts criticism, it moves to exploring the history of ideas in philosophy, the arts and science about holism and the challenge of researching health and illness within the complexity of being fully human. © The Author(s) 2015.

From cutting nature and its joints to measuring it: new kinds and new kinds of people in biology.

PubMed

McOuat, G

2001-12-01

In the received version of the development of science, natural kinds are established in the preliminary stages (natural history) and made more precise by measurement (exact science). By examining the move from nineteenth- to twentieth-century biology, this paper unpacks the notion of species as 'natural kinds' and grounds for discourse, questioning received notions about both kinds and species. Life sciences in the nineteenth century established several 'monster-barring' techniques to block disputes about the precise definition of species. Counterintuitively, precision and definition brought dispute and disrupted exchange. Thus, any attempt to add precision was doomed to failure. By intervening and measuring, the new experimental biology dislocated the established links between natural kinds and kinds of people and institutions. New kinds were built in new places. They were made to measure from the very start. This paper ends by claiming that there was no long-standing 'species problem' in the history of biology. That problem is a later construction of the 'modern synthesis', well after the disruption of 'kinds' and kinds of people. Only then would definitions and precision matter. A new, non-linguistic, take on the incommensurability thesis is hinted at. Copyright 2001 Elsevier Science Ltd. All rights reserved.

Smallsats, Cubesats and Scientific Exploration

Stofan, E. R.

2015-12-01

Smallsats (including Cubesats) have taken off in the aerospace research community - moving beyond simple tools for undergraduate and graduate students and into the mainstream of science research. Cubesats started the "smallsat" trend back in the late 1990's early 2000's, with the first Cubesats launching in 2003. NASA anticipates a number of future benefits from small satellite missions, including lower costs, more rapid development, higher risk tolerance, and lower barriers to entry for universities and small businesses. The Agency's Space Technology Mission Directorate is currently addressing technology gaps in small satellite platforms, while the Science Mission Directorate pursues miniaturization of science instruments. Launch opportunities are managed through the Cubesat Launch Initiative, and the Agency manages these projects as sub-orbital payloads with little program overhead. In this session we bring together scientists and technologists to discuss the current state of the smallsat field. We explore ideas for new investments, new instruments, or new applications that NASA should be investing in to expand the utility of smallsats. We discuss the status of a NASA-directed NRC study on the utility of small satellites. Looking to the future, what does NASA need to invest in now, to enable high impact ("decadal survey" level) science with smallsats? How do we push the envelope? We anticipate smallsats will contribute significantly to a more robust exploration and science program for NASA and the country.

Uganda has a long history of health research, but still faces critical health problems. It has made a number of recent moves towards building science and technology capacity which could have an impact on local health, if innovation can be fostered and harnessed. Qualitative case study research methodology was used. Data were collected through reviews of academic literature and policy documents and through open-ended, face-to-face interviews with 30 people from across the science-based health innovation system, including government officials, researchers in research institutes and universities, entrepreneurs, international donors, and non-governmental organization representatives. Uganda has a range of institutions influencing science-based health innovation, with varying degrees of success. However, the country still lacks a coherent mechanism for effectively coordinating STI policy among all the stakeholders. Classified as a least developed country, Uganda has opted for exemptions from the TRIPS intellectual property protection regime that include permitting parallel importation and providing for compulsory licenses for pharmaceuticals. Uganda is unique in Africa in taking part in the Millennium Science Initiative (MSI), an ambitious though early-stage $30m project, funded jointly by the World Bank and Government of Uganda, to build science capacity and encourage entrepreneurship through funding industry-research collaboration. Two universities - Makerere and Mbarara - stand out in terms of health research, though as yet technology development and commercialization is weak. Uganda has several incubators which are producing low-tech products, and is beginning to move into higher-tech ones like diagnostics. Its pharmaceutical industry has started to create partnerships which encourage innovation. Science-based health product innovation is in its early stages in Uganda, as are policies for guiding its development. Nevertheless, there is political will for the development of STI in Uganda, demonstrated through personal initiatives of the President and the government's willingness to invest heavily for the long term in support of STI through the Millennium Science Initiative. Activities to support technology transfer and private-public collaboration have been put in motion; these need to be monitored, coordinated, and learned from. In the private sector, there are examples of incremental innovation to address neglected diseases driven by entrepreneurial individuals and South-South collaboration. Lessons can be learned from their experience that will help support Ugandan health innovation.

To evaluate the changes in maxillary position after maxillary distraction osteogenesis in six growing children with cleft lip and palate. Retrospective, longitudinal study on maxillary changes at A point, anterior nasal spine, posterior nasal spine, central incisor, and first molar. The University Hospital Craniofacial Center. Cephalometric radiographs were used to measure the maxillary position immediately after distraction, at 6 months, and more than 1 year after distraction. After maxillary distraction with a rigid external distraction device, the maxilla (A point) on average moved forward 9.7 mm and downward 3.5 mm immediately after distraction, moved backward 0.9 mm and upward 2.0 mm after 6 months postoperatively, and then moved further backward 2.3 mm and downward 6.8 mm after more than 1 year from the predistraction position. In most cases, maxilla moved forward at distraction and started to move backward until 1 year after distraction, but remained forward, as compared with predistraction position. Maxilla also moved downward during distraction and upward in 6 months, but started descending in 1 year. There also was no further forward growth of the maxilla after distraction in growing children with clefts.

Computational methods in the exploration of the classical and statistical mechanics of celestial scale strings: Rotating Space Elevators

NASA Astrophysics Data System (ADS)

Knudsen, Steven; Golubovic, Leonardo

2015-04-01

With the advent of ultra-strong materials, the Space Elevator has changed from science fiction to real science. We discuss computational and theoretical methods we developed to explore classical and statistical mechanics of rotating Space Elevators (RSE). An RSE is a loopy string reaching deep into outer space. The floppy RSE loop executes a motion which is nearly a superposition of two rotations: geosynchronous rotation around the Earth, and yet another faster rotational motion of the string which goes on around a line perpendicular to the Earth at its equator. Strikingly, objects sliding along the RSE loop spontaneously oscillate between two turning points, one of which is close to the Earth (starting point) whereas the other one is deeply in the outer space. The RSE concept thus solves a major problem in space elevator science which is how to supply energy to the climbers moving along space elevator strings. The exploration of the dynamics of a floppy string interacting with objects sliding along it has required development of novel finite element algorithms described in this presentation. We thank Prof. Duncan Lorimer of WVU for kindly providing us access to his computational facility.

Geoethical implications for geoarchaeology. The Laacher See and AD 536 case studies

NASA Astrophysics Data System (ADS)

Riede, Felix; Price, Neil; Andersen, Per

2017-04-01

Environmental catastrophes represent profound challenges faced by societies today. Numerous scholars in the climate sciences as well as the Humanities have argued for a greater ethical engagement with these pressing issues. At the same time, several disciplines concerned with hazards are moving towards formalized ethical codes or promises that guide not only the dissemination of data but oblige scientists to relate to fundamentally political issues. With its starting point in the recently proposed geoethical promise, this paper reports on two case studies of how past natural hazards have affected vulnerable societies in Europe's past. We ask whether cases of past calamities and their societal effects should not play a greater role in public debates and whether geo-archaeologists working with past environmental hazards should be more outspoken in their ethical considerations. We offer no firm answers, but suggest that geo-archaeologists engage with debates of human-environment relations at this interface between politics, public affairs and science. We argue for greater communication between the human and natural sciences and further suggest that outreach institutions such as museums - both natural and cultural - could and perhaps should play a key role in staging such engagements.

[E. M. Jellinek's silenced and silencing transgenerational story].

Kelemen, Gábor; Márk, Mónika

2013-01-01

Jellinek is a kind of archetypal character for future generations in the field of addiction studies. His implosion in the arena of alcoholism around the age of 50 was an unexpected challenge to medical science. We know very little about his own role models giving an intellectual and moral compass to his pragmatic creativity. More than 30 years has passed since Jellinek's death when an American sociologist Ron Roizen started unearthing his silent story. Roizen discerned that there are a lot of unsaid and muted issues in his personal Hungarian past. Our paper, based on the authors' research in Hungarian archives and other sources reveals that not just Jellinek's personal but his transgenerational narrative has been not-yet-said. This silenced and silencing history appears an unfinished business of acculturation of the family, which started prior to four generations. Authors have been concluding that the issue of religious conversion is a critical point in the process of acculturation. They examine the counter move of loyalty to family values and driving force of assimilation making their story unspeakable.

Breaking the Vicious Start-Stop-Restart Cycle

NASA Technical Reports Server (NTRS)

Singer, Christopher E.

2011-01-01

NASA's history is built on a foundation of can-do strength, while pointing to the Apollo Moon missions in the 1960s and 1970s as its apex a sentiment that often overshadows the potential in store. The chronicle of America s civil space adventure is scattered with programs that got off to good starts with adequate resources and vocal political support but that never made it past a certain milestone review, General Accountability Office report, or Congressional budget appropriation. Over the decades since the fielding of the Space Shuttle in the early 1980s, a start-stop-restart cycle has intervened due to many forces. Despite this impediment, the workforce has delivered feats such as the International Space Station and numerous Shuttle and science missions, which reflect a trend in the early days of the Exploration Age that called for massive infrastructure and matching capital allocations. In the new millennium, the aerospace industry must respond to transforming economic climates, the public will, national agendas, and international possibilities relative to scientific exploration beyond Earth's orbit. Two pressing issues workforce transition and mission success are intertwined. As this briefing will show, U.S. aerospace must confront related workforce development and industrial base issues head on to take space exploration to the next level. This briefing also will formulate specific strategies to equip space engineers to move beyond the seemingly constant start-stop-restart mentality to plan and execute flight projects that actually fly.

Breakout Reconnection Observed by the TESIS EUV Telescope

2016-01-01

We present experimental evidence of the coronal mass ejection (CME) breakout reconnection, observed by the TESIS EUV telescope. The telescope could observe solar corona up to 2 R⊙ from the Sun center in the Fe 171 Å line. Starting from 2009 April 8, TESIS observed an active region (AR) that had a quadrupolar structure with an X-point 0.5 R⊙ above photosphere. A magnetic field reconstructed from the Michelson Doppler Imager data also has a multipolar structure with an X-point above the AR. At 21:45 UT on April 9, the loops near the X-point started to move away from each other with a velocity of ≈7 km s-1. At 01:15 UT on April 10, a bright stripe appeared between the loops, and the flux in the GOES 0.5-4 Å channel increased. We interpret the loops’ sideways motion and the bright stripe as evidence of the breakout reconnection. At 01:45 UT, the loops below the X-point started to slowly move up. At 15:10 UT, the CME started to accelerate impulsively, while at the same time a flare arcade formed below the CME. After 15:50 UT, the CME moved with constant velocity. The CME evolution precisely followed the breakout model scenario.

A repulsive magnetic force driven translation micromirror

NASA Astrophysics Data System (ADS)

Xue, Yuan; Zuo, Hui; He, Siyuan

2017-10-01

This paper presents a repulsive magnetic force driven micromirror with large displacement and high surface quality which well solves the limitation of the previous design, i.e. large variation in translation starting position and low repeatability, caused by the touching points between the moving film and substrate before and in operation. The new design utilizes a driving mechanism, i.e. permanent magnet ring above and electromagnet underneath the moving film, to lift the moving film from touching the substrate and generate a repulsive magnetic force (instead of attractive force in the previous design) to push the moving film up and away from the substrate for translation. Due to the touching, the previous design has to pre-oscillate for 20-30 min at 1 Hz before usage (after resting for a few hours) to reduce the starting position variation from ~15 µm to 3-4 µm. Even after the pre-oscillation, the repeatability is still low, which is 14.2% because of the touching in operation. In the design presented in this paper, the touching between the moving film and the substrate is completely eliminated before and in operation. As a result, the starting position of the translating mirror is constant each time and the repeatability is  <1%. In addition, this design does not need the residual stress gradient to curve up the moving film. The maximum displacement of 144 µm can be achieved when 140 mA current is applied on the electromagnet. As an application, the micromirror is used as the movable mirror in a Michelson interferometer to measure the wavelength of a laser beam. The result shows a measurement accuracy of 2.19% for a 532 nm laser beam.

The concept of governance in dual-use research.

PubMed

Dubov, Alex

2014-08-01

The rapid advance of life science within the context of increased international concern over the potential misuse of findings has resulted in the lack of agreement on the issues of responsibility, control and collaboration. This progress of knowledge outpaces the efforts of creating moral and legal guidelines for the detection and minimization of the risks in the research process. There is a need to identify and address normative aspects of dual-use research. This paper focuses on the issues of safety and global collaboration in life science research by highlighting the importance of openness, enabling policies and cooperative governance. These safeguards are believed to reduce the risks related to the misuse of science while enabling the important research to move forward. The paper addresses the need for a better definition of dual use concept and, based on the historical precedents, explores the moral concerns and governmental strategies of dual-use research. The three necessary moves in addressing the issue of security in life sciences are suggested: the move from constraining to enabling types of policies, the move from secrecy to openness, and the move from segregation to integration of the public voice.

In August 2013, we held a panel discussion at the KDD 2013 conference in Chicago on the subject of data science, data scientists, and start-ups. KDD is the premier conference on data science research and practice. The panel discussed the pros and cons for top-notch data scientists of the hot data science start-up scene. In this article, we first present background on our panelists. Our four panelists have unquestionable pedigrees in data science and substantial experience with start-ups from multiple perspectives (founders, employees, chief scientists, venture capitalists). For the casual reader, we next present a brief summary of the experts' opinions on eight of the issues the panel discussed. The rest of the article presents a lightly edited transcription of the entire panel discussion.

Water reservoir maintained by cell growth fuels the spreading of a bacterial swarm

Flagellated bacteria can swim across moist surfaces within a thin layer of fluid, a means for surface colonization known as swarming. This fluid spreads with the swarm, but how it does so is unclear. We used micron-sized air bubbles to study the motion of this fluid within swarms of Escherichia coli. The bubbles moved diffusively, with drift. Bubbles starting at the swarm edge drifted inward for the first 5 s and then moved outward. Bubbles starting 30 μm from the swarm edge moved inward for the first 20 s, wandered around in place for the next 40 s, and then moved outward. Bubbles starting at 200 or 300 μm from the edge moved outward or wandered around in place, respectively. So the general trend was inward near the outer edge of the swarm and outward farther inside, with flows converging on a region about 100 μm from the swarm edge. We measured cellular metabolic activities with cells expressing a short-lived GFP and cell densities with cells labeled with a membrane fluorescent dye. The fluorescence plots were similar, with peaks about 80 μm from the swarm edge and slopes that mimicked the particle drift rates. These plots suggest that net fluid flow is driven by cell growth. Fluid depth is largest in the multilayered region between approximately 30 and 200 μm from the swarm edge, where fluid agitation is more vigorous. This water reservoir travels with the swarm, fueling its spreading. Intercellular communication is not required; cells need only grow. PMID:22371567

GIARPS (GIAno and haRPS) is a project devoted to have on the same focal station of the Telescopio Nazionale Galileo (TNG) both the high resolution spectrographs HARPS-N (VIS) and GIANO (NIR) working simultaneously. This could be considered the first and unique worldwide instrument providing cross-dispersed echelle spectroscopy at a high resolution (R=115,000 in the visual and R=50,000 in the IR) and over in a wide spectral range (0.383 - 2.45 μm) in a single exposure. The science case is very broad, given the versatility of such an instrument and the large wavelength range. A number of outstanding science cases encompassing mainly extra-solar planet science starting from rocky planet search and hot Jupiters, atmosphere characterization can be considered. Furthermore both instrument can measure high precision radial velocity by means the simultaneous thorium technique (HARPS - N) and absorbing cell technique (GIANO) in a single exposure. Other science cases are also possible. Young stars and proto- planetary disks, cool stars and stellar populations, moving minor bodies in the solar system, bursting young stellar objects, cataclysmic variables and X-ray binary transients in our Galaxy, supernovae up to gamma-ray bursts in the very distant and young Universe, can take advantage of the unicity of this facility both in terms of contemporaneous wide wavelength range and high resolution spectroscopy.

A Shifting Baseline: Higher Degrees and Career Options for Ocean Scientists

Yoder, J. A.; Briscoe, M. G.; Glickson, D.; Roberts, S.; Spinrad, R. W.

2016-02-01

As for other fields of science, a Ph.D. degree in the ocean sciences no longer guarantees an academic position. In fact, recent studies show that while most earning a Ph.D. in the ocean sciences today may start in academia as a postdoc, an undetermined number of postdocs may not move into university faculty positions or comparable positions at basic research institutions. Although the data are few, some believe that most of those now earning Ph.D. degrees in ocean science are eventually employed outside of academia. Changes to the career path for those entering ocean science graduate programs today is both a challenge and an opportunity for graduate programs. Some graduates of course do continue in academia. For those students who are determined to follow that path, graduate programs need to prepare them for that choice. On the other hand, graduate programs also have an obligation to provide students with the information they need to make educated career decisions - there are interesting career choices other than academia for those earning a Ph.D. or finishing with a terminal M.S. degree. Furthermore, graduate programs need to encourage students to think hard about their career expectations early in their graduate program to ensure they acquire the skills needed to keep career options open. This talk will briefly review some of the recent studies related to the career paths of those who recently acquired a Ph.D. in ocean sciences and other fields; describe possible career options for those who enter ocean science graduate programs; encourage more attention on the career possibilities of a terminal ocean science M.S. degree perhaps combined with another higher degree in a different field; and discuss the skills a graduate student can acquire that increase the breadth of career path opportunities.

Pierce, Eric M.; Freshley, Mark D.; Hubbard, Susan S.

In this report, we start by examining previous efforts at linking science and DOE EM research with cleanup activities. Many of these efforts were initiated by creating science and technology roadmaps. A recurring feature of successfully implementing these roadmaps into EM applied research efforts and successful cleanup is the focus on integration. Such integration takes many forms, ranging from combining information generated by various scientific disciplines, to providing technical expertise to facilitate successful application of novel technology, to bringing the resources and creativity of many to address the common goal of moving EM cleanup forward. Successful projects identify and focusmore » research efforts on addressing the problems and challenges that are causing “failure” in actual cleanup activities. In this way, basic and applied science resources are used strategically to address the particular unknowns that are barriers to cleanup. The brief descriptions of the Office of Science basic (Environmental Remediation Science Program [ERSP]) and EM’s applied (Groundwater and Soil Remediation Program) research programs in subsurface science provide context to the five “crosscutting” themes that have been developed in this strategic planning effort. To address these challenges and opportunities, a tiered systematic approach is proposed that leverages basic science investments with new applied research investments from the DOE Office of Engineering and Technology within the framework of the identified basic science and applied research crosscutting themes. These themes are evident in the initial portfolio of initiatives in the EM groundwater and soil cleanup multi-year program plan. As stated in a companion document for tank waste processing (Bredt et al. 2008), in addition to achieving its mission, DOE EM is experiencing a fundamental shift in philosophy from driving to closure to enabling the long-term needs of DOE and the nation.« less

Control of molt in birds: association with prolactin and gonadal regression in starlings.

PubMed

Dawson, Alistair

2006-07-01

Despite the importance of molt to birds, very little is known about its environmental or physiological control. In starlings Sturnus vulgaris, and other species, under both natural conditions and experimental regimes, gonadal regression coincides with peak prolactin secretion. The prebasic molt starts at the same time. The aim of this series of experiments was to keep starlings on photo-schedules that would challenge the normally close relationship between gonadal regression and molt, to determine how closely the start of molt is associated with gonadal regression and/or associated changes in prolactin concentrations. In one series of experiments, photosensitive starlings were moved from a short photoperiod, 8 h light per day (8L), to 13 or 18L, and from 13 to 18L or 13 to 8L during testicular maturation. Later, photorefractory birds under 13L that had finished molting were moved to 18L. In another series of experiments, photorefractory starlings were moved from 18 to 8L for 7 weeks, 4 weeks, 2 weeks, 1 week, 3 days, 1 day, or 0 days, before being returned to 18L. There was no consistent relationship between photoperiod, or the increase in photoperiod, and the timing of the start of molt. Nor was there a consistent relationship with gonadal regression and the start of molt-molt could be triggered in the absence of a gonadal cycle. However, there was always an association between the start of molt and prolactin. In all cases where molt was induced, there had been an earlier increase in prolactin. However, the timing of molt was related to the time of peak prolactin, not the magnitude of that peak. This relationship between peak prolactin and the start of molt could explain the normally close relationship between the end of breeding activity and the start of molt.

Getting to First Flight: Equipping Space Engineers to Break the Start-Stop-Restart Cycle

The National Aeronautics and Space Administration s (NASA s) history is built on a foundation of can-do strength, while pointing to the Saturn/Apollo Moon missions in the 1960s and 1970s as its apex a sentiment that often overshadows the potential that lies ahead. The chronicle of America s civil space agenda is scattered with programs that got off to good starts with adequate resources and vocal political support but that never made it past a certain milestone review, General Accountability Office report, or Congressional budget appropriation. Over the decades since the fielding of the Space Shuttle in the early 1980s, a start-stop-restart cycle has intervened due to many forces. Despite this impediment, the workforce has delivered engineering feats such as the International Space Station and numerous Shuttle and science missions, which reflect a trend in the early days of the Exploration Age that called for massive infrastructure and matching capital allocations. In the new millennium, the aerospace industry must respond to transforming economic climates, the public will, national agendas, and international possibilities relative to scientific exploration beyond Earth s orbit. Two pressing issues - workforce transition and mission success - are intertwined. As this paper will address, U.S. aerospace must confront related workforce development and industrial base issues head on to take space exploration to the next level. This paper also will formulate specific strategies to equip space engineers to move beyond the seemingly constant start-stop-restart mentality to plan and execute flight projects that actually fly.

Next Generation Cloud-based Science Data Systems and Their Implications on Data and Software Stewardship, Preservation, and Provenance

NASA Astrophysics Data System (ADS)

Hua, H.; Manipon, G.; Starch, M.

2017-12-01

NASA's upcoming missions are expected to be generating data volumes at least an order of magnitude larger than current missions. A significant increase in data processing, data rates, data volumes, and long-term data archive capabilities are needed. Consequently, new challenges are emerging that impact traditional data and software management approaches. At large-scales, next generation science data systems are exploring the move onto cloud computing paradigms to support these increased needs. New implications such as costs, data movement, collocation of data systems & archives, and moving processing closer to the data, may result in changes to the stewardship, preservation, and provenance of science data and software. With more science data systems being on-boarding onto cloud computing facilities, we can expect more Earth science data records to be both generated and kept in the cloud. But at large scales, the cost of processing and storing global data may impact architectural and system designs. Data systems will trade the cost of keeping data in the cloud with the data life-cycle approaches of moving "colder" data back to traditional on-premise facilities. How will this impact data citation and processing software stewardship? What are the impacts of cloud-based on-demand processing and its affect on reproducibility and provenance. Similarly, with more science processing software being moved onto cloud, virtual machines, and container based approaches, more opportunities arise for improved stewardship and preservation. But will the science community trust data reprocessed years or decades later? We will also explore emerging questions of the stewardship of the science data system software that is generating the science data records both during and after the life of mission.

The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that presented 28 papers. The last one, in Uberlandia, Minas Gerais had 3000 participants with 66 conferences and keynotes and more than 4000 papers presented. The next will happen in August 2013 in Florianopolis, Santa Catarina and is also limited to 3000 participants. Beside the national soil science meetings, in its 65 years, the Society also promoted 26 editions of the Brazilian Meeting of Management and Conservation of Soil and Water, 23 editions of the Brazilian Meeting of Soil Fertility and Plant Nutrition, 6 editions of the Brazilian Meeting of Fertility and Soil Biology and six editions the Brazilian Simposium on Soil Education, and co-sponsored the ten editions of the Soil Classification and Correlation Meeting. In the last years it is also increasing the number of regional meetings organized by the regional nuclei. In 2011, during the Brazilian Congress of Soil Science, a new Board of Directors (known as the Council) was elected. Since then the Society is setting up a modernization process in its structures and external relations through a renewed statute and new by-laws. The Council, composed by 20 members, is developing an agenda and strategic planning for the next years that reinforces that the Society should aim to: (a) become more influent in Brazilian environmental public policies, (b) reach leadership in public soil awareness in a continental-sized country like Brazil and (c) interact more actively with other scientific societies due to the transdisciplinary nature of Soil Science, and work hard to go out of the agronomical box. At present, the society is busy with the organization of the 21st World Congress of Soil Science to happen in 2018, for the first time in Brazil. Preceding it the Society is organizing a wide range of activities and events to celebrate and call public attention to Soils, in special on the occasion of the International Year of Soils, in 2017.

This study aimed to investigate biofilm properties evolution coupled with different ages during the start-up period in a moving bed biofilm reactor system. Physicochemical characteristics including adhesion force, extracellular polymeric substances (EPS), morphology as well as volatile solid and microbial community were studied. Results showed that the formation and development of biofilms exhibited four stages, including (I) initial attachment and young biofilm formation, (II) biofilms accumulation, (III) biofilm sloughing and updating, and (IV) biofilm maturation. During the whole start-up period, adhesion force was positively and significantly correlated with the contents of EPS, especially the content of polysaccharide. In addition, increased adhesion force and EPS were beneficial for biofilm retention. Gram-negative bacteria mainly including Sphaerotilus, Zoogloea and Haliscomenobacter were predominant in the initial stage. Actinobacteria was beneficial to resist sloughing. Furthermore, filamentous bacteria were dominant in maturation biofilm. Copyright © 2015 Elsevier Ltd. All rights reserved.

The discourse of causal explanations in school science

NASA Astrophysics Data System (ADS)

Slater, Tammy Jayne Anne

Researchers and educators working from a systemic functional linguistic perspective have provided a body of work on science discourse which offers an excellent starting point for examining the linguistic aspects of the development of causal discourse in school science, discourse which Derewianka (1995) claimed is critical to success in secondary school. No work has yet described the development of causal language by identifying the linguistic features present in oral discourse or by comparing the causal discourse of native and non-native (ESL) speakers of English. The current research responds to this gap by examining the oral discourse collected from ESL and non-ESL students at the primary and high school grades. Specifically, it asks the following questions: (1) How do the teachers and students in these four contexts develop causal explanations and their relevant taxonomies through classroom interactions? (2) What are the causal discourse features being used by the students in these four contexts to construct oral causal explanations? The findings of the social practice analysis showed that the teachers in the four contexts differed in their approaches to teaching, with the primary school mainstream teacher focusing largely on the hands-on practice , the primary school ESL teacher moving from practice to theory, the high school mainstream teacher moving from theory to practice, and the high school ESL teacher relying primarily on theory. The findings from the quantitative, small corpus approach suggest that the developmental path of cause which has been identified in the writing of experts shows up not only in written texts but also in the oral texts which learners construct. Moreover, this move appears when the discourse of high school ESL and non-ESL students is compared, suggesting a developmental progression in the acquisition of these features by these students. The findings also reveal that the knowledge constructed, as shown by the concept maps created from the discourse, follows a developmental path similar to the linguistic causal path, from the concrete, hands-on, observable items to more abstract, theoretical concepts. This study is the first systemic functional comparison of the oral discourse of primary and secondary learners as well as the first to compare ESL and non-ESL speakers in this way, and as such it helps map general trends in causal discourse development.

2018-01-01

This study aims to investigate Grade 11 students' views on Science Technology Engineering Mathematics (STEM) with the integration of learning about electrical current based on Science Technology Society (STS) approach [8]. The participants were 60 Grade 11 students in Demonstration Secondary School, Khon Kaen University, Khon Kaen Province, Thailand. The methodology is in the respect of interpretive paradigm. The teaching and learning about Electrical Current through STS approach carried out over 6 weeks. The Electrical Current unit through STS approach was developed based on framework[8] that consists of five stages including (1) identification of social issues, (2) identification of potential solutions, (3) need for knowledge, (4) decision making, and (5) socialization stage. To start with, the question "what if this world is lack of electricity" was challenged in the class in order to move students to find the problem of how to design Electricity Generation from Clean Energy. Students were expected to apply scientific and other knowledge to design of Electricity Generation. Students' views on STEM were collected during their learning by participant' observation and students' tasks. Their views on STEM were categorized when they applied their knowledge for designing the Electricity Generation. The findings indicated that students cooperatively work to solve the problem when applying knowledge about the content of Science and Mathematics and processing skill of Technology and Engineering. It showed that students held the integration of science, technology, engineering and mathematics to design their possible solutions in learning about Electrical Current. The paper also discusses implications for science teaching and learning through STS in Thailand.

All Christians? Experiences of science educators in Northern Ireland

NASA Astrophysics Data System (ADS)

Murphy, Colette; Hickey, Ivor; Beggs, Jim

2010-03-01

In this paper we respond to Staver's article (this issue) on an attempt to resolve the discord between science and religion. Most specifically, we comment on Staver's downplaying of difference between Catholics and Protestants in order to focus on the religion-science question. It is our experience that to be born into one or other of these traditions in some parts of the world (especially Northern Ireland) resulted in starkly contrasting opportunities, identities and practices in becoming and being science educators. The paper starts with a short contextual background to the impact of religion on schooling and higher education in Northern Ireland. We then explore the lives and careers of three science/religious educators in Northern Ireland: Catholic (Jim) and Protestant (Ivor) males who are contemporaries and whose experience spans pre-Troubles to post-conflict and a Catholic female (Colette) who moved to Northern Ireland during the Troubles as a teenager. Finally, we discuss the situation regarding the teaching of creationism and evolution in Northern Ireland—an issue has recently generated high public interest. The Chair of the Education Committee of the Northern Ireland Assembly recently stated that "creationism is not for the RE class because I believe that it can stand scientific scrutiny and that is a debate which I am quite happy to encourage and be part of…" (News Letter 2008). It could be the case that the evolution debate is being fuelled as a deliberate attempt to undermine some of the post-conflict collaboration projects between schools and communities in Northern Ireland.

Effects of pushing height on trunk posture and trunk muscle activity when a cart suddenly starts or stops moving.

PubMed

Lee, Yun-Ju; Hoozemans, Marco J M; van Dieën, Jaap H

2012-01-01

Unexpected sudden (un)loading of the trunk may induce inadequate responses of trunk muscles and uncontrolled trunk motion. These unexpected perturbations may occur in pushing tasks, when the cart suddenly starts moving (unloading) or is blocked by an obstacle (loading). In pushing, handle height affects the user's working posture, which may influence trunk muscle activity and trunk movement in response to the perturbation. Eleven healthy male subjects pushed a 200 kg cart with handles at shoulder and hip height in a start condition (sudden release of brakes) and a stop condition (bumping into an obstacle). Before the perturbation, the baseline of the trunk inclination, internal moment and trunk extensor muscle activity were significantly higher when pushing at hip height than at shoulder height. After the perturbation, the changes in trunk inclination and internal moment were significantly larger when pushing at shoulder height than at hip height in both conditions. The opposite directions of changes in trunk inclination and internal moment suggest that the unexpected perturbations caused uncontrolled trunk motion. Pushing at shoulder height may impose a high risk of low-back injury due to the low trunk stiffness and large involuntary trunk motion occurring after carts suddenly move or stop.

Fifty-four Years of Adventures in Infrared Astronomy

NASA Astrophysics Data System (ADS)

Becklin, Eric Eric

2018-01-01

My adventures in infrared astronomy started when I was a grad student in 1965 with the discovery of an infrared-bright object (now known as the Becklin-Neugebauer Object) in the Orion Nebula. In 1966, I made the first measurements of the infrared radiation from the center of the Milky Way Galaxy. I was fortunate enough to be able to take advantage of the 2.2 micron sky survey carried out by Neugebauer and Leighton (1969), which produced many remarkable discoveries, the most spectacular being the heavily dust-embedded carbon star IRC+10216, thebrightest object in the sky at 5 microns outside the solar system. In the 1970’s there was a growth in Infrared astronomy with the availability of many new facilities such as the Kuiper Airborne Observatory, (KAO) which I used extensively with Mike Werner and Ian Gatley for many unique observations. In 1977, I moved to Hawaii to work on the NASA IRTF 3- meter telescope. Many discoveries were made, including the first direct measurements of the rings of Jupiter at 2.2 microns (with Gareth Wynn-Williams) and the discovery of the first L dwarf star around a white dwarf (with Ben Zuckerman). In the 1980’s the introduction of large format arrays changed the way we did infrared astronomy. With Ian McLean, I moved to UCLA in 1990 to start the IR lab and get involved in Keck development and science. In 1995, Andrea, Ghez, Mark Morris and I started looking for evidence of a possible massive Black Hole in the Galactic Center. Spectacular observations using the Keck10 meter telescopes with large format near-infrared arrays and adaptive optics led to the confirmation of the presence of such a black hole and an estimate of its mass (4xE6 M (Sun)). In 1996, I began working on the Stratospheric Observatory For Infrared Astronomy (SOFIA) and I will finish my talk by discussing SOFIA observations of the ring of dust and gas orbiting the massive black hole in the center

Moving Green Chemistry Forward: Networks as a Foundation

NASA Astrophysics Data System (ADS)

Carter, T.; Lough, G.

2014-12-01

Green chemistry is a growing discipline, but for a variety of reasons, it has not yet become integrated into science curriculum and the greater societal conscience. With its increasing economic benefits to many sectors including business, industry, and academia and its potential to make science more accessible not only to science students but also to the general citizenry, we suggested answers to the questions: Why has greater success not been realized? What are the particular barriers to wider implementation? And what are incentives and ways to move green chemistry forward? We suggest some strategies and options to both increase the use of green chemistry principles and to also increase stakeholders' understanding of the importance and utility of green chemistry in their daily lives. For example, our main suggestions are that an inclusive, multidisciplinary network would aid in coordinating data and in translating the science into user friendly tools, and that an educational component embedded in this greater effort would also serve to move green chemistry forward.

2016-01-01

Although spacecraft developers have been moving towards standardized product lines as the aerospace industry has matured, NASA's continual need to push the cutting edge of science to accomplish unique, challenging missions can still lead to spacecraft resource growth over time. This paper assesses historical mass, power, cost, and schedule growth for multiple NASA spacecraft from the last twenty years and compares to industry reserve guidelines to understand where the guidelines may fall short. Growth is assessed from project start to launch, from the time of the preliminary design review (PDR) to launch and from the time of the critical design review (CDR) to launch. Data is also assessed not just at the spacecraft bus level, but also at the subsystem level wherever possible, to help obtain further insight into possible drivers of growth. Potential recommendations to minimize spacecraft mass, power, cost, and schedule growth for future missions are also discussed.

CAPE CANAVERAL, Fla. – Team members check their robot before the start of a mining session in simulated Martian soil in the Caterpillar Mining Arena during NASA’s 2014 Robotic Mining Competition at the Kennedy Space Center Visitor Complex in Florida. More than 35 teams from colleges and universities around the U.S. have designed and built remote-controlled robots for the mining competition. The competition is a NASA Human Exploration and Operations Mission Directorate project designed to engage and retain students in science, technology, engineering and mathematics, or STEM, fields by expanding opportunities for student research and design. Teams use their remote-controlled robotics to maneuver and dig in a supersized sandbox filled with a crushed material that has characteristics similar to Martian soil. The objective of the challenge is to see which team’s robot can collect and move the most regolith within a specified amount of time. For more information, visit www.nasa.gov/nasarmc.

History of modern genetics in Germany.

PubMed

Hammar, Friederike

2002-01-01

The history of modern genetics in Germany during the 20th century is a story of missed chances. In the USA the genetic revolution opened a fascinating new field for ambitious scientists and created a rapidly growing new industry. Meanwhile Germany stood aside, combating with political and social restrictions. Promising young scientists who wanted to work in the field left Germany for the US, and big companies moved their facilities out of the country. Up until the middle of the 1990s molecular biology in Germany remained a "sleeping beauty" even though many brilliant scientists did their jobs very well. Then a somewhat funny idea changed everything: the German minister for education and science proclaimed the BioRegio contest in order to award the most powerful biotechnology region in Germany concerning academia and especially industry. Since then Germany's biotechnology industry has grown constantly and rapidly due to the foundation of a number of small biotech companies; big companies have returned their interests and their investments to Germany, paralleled by an improvement in academic research because of more funding and better support especially for younger scientists. In respect to biotechnology and molecular biology, Germany is still a developing country, but it has started to move and to take its chances in an exciting global competition.

Elucidating the electron transport in semiconductors via Monte Carlo simulations: an inquiry-driven learning path for engineering undergraduates

NASA Astrophysics Data System (ADS)

Persano Adorno, Dominique; Pizzolato, Nicola; Fazio, Claudio

2015-09-01

Within the context of higher education for science or engineering undergraduates, we present an inquiry-driven learning path aimed at developing a more meaningful conceptual understanding of the electron dynamics in semiconductors in the presence of applied electric fields. The electron transport in a nondegenerate n-type indium phosphide bulk semiconductor is modelled using a multivalley Monte Carlo approach. The main characteristics of the electron dynamics are explored under different values of the driving electric field, lattice temperature and impurity density. Simulation results are presented by following a question-driven path of exploration, starting from the validation of the model and moving up to reasoned inquiries about the observed characteristics of electron dynamics. Our inquiry-driven learning path, based on numerical simulations, represents a viable example of how to integrate a traditional lecture-based teaching approach with effective learning strategies, providing science or engineering undergraduates with practical opportunities to enhance their comprehension of the physics governing the electron dynamics in semiconductors. Finally, we present a general discussion about the advantages and disadvantages of using an inquiry-based teaching approach within a learning environment based on semiconductor simulations.

Nationally, many public universities have started to move into the online course and program market that is most often associated with for-profit institutions of higher education. Administrators in public universities make statements regarding benefits to students' desire for flexibility and profit margins related to online courses. But do students attending a large public university want to take courses online especially science courses perceived to be difficult such as freshmen-level physics courses? This study took place at a large, public, Midwestern university and involved students enrolled in the first semester of a face-to-face, flipped physics course for engineering technology majors. Statements were collected from comments about online courses made by the university's administration and students in the course. Twenty students sorted 45 statements. Two student views emerged with one rejecting online courses in general and the other primarily rejecting online math, science, and technology courses, including physics. Students' descriptions of their previous online course experiences were used to inform the analyses and to assist in describing the two views that emerged in conjunction with the distinguishing statements. Consensus among the two views is also discussed. Overall, the results indicate a potential divergence between student views and what university administrators believe students want.

Blending the art and science of color

NASA Astrophysics Data System (ADS)

Bourges, Jean

1998-07-01

An often neglected factor of cognition is the color, the natural and created hues that are an integral part of the image. This happens because the information is divided in two basically very different languages and they do not relate well to each other. One is for science that deals in facts and uses numbers to transmit the message. The other relates to intangibles and is used for the Arts. One speaks to reality and the other to emotions. Both are valid and correctly address the needs of their profession. Not very long ago the digital world was born. The computer came and put it all together in one little box, that probably sits on your desk and is accessible to most everyone else. Now there is the need to communicate and because the box only understands numbers, the artists have to shift and identify the colors by a simple numerical code. Conversely science can learn a lot from the arts, where for centuries painters have been studying the mysteries of creating light on canvas. While color needs a responsive set of eyes, it has always been here. Let us start now by using the same words to identify a particular color, its tint and shade, how the artists use it, the essential structure that lets one move from one color to another and the colorimetric measurements that make the exact color match a practical reality.

New Approach to Quantum Entanglement According to the Theory of the Harmonicity of the Field of Light

NASA Astrophysics Data System (ADS)

Raftopoulos, Dionysios G.

Werner Heisenberg's well known requirement that Physical Science ought to occupy itself solely with entities that are both observable and measurable, is almost universally accepted. Starting from the above thesis and accepting Albert Einstein's second fundamental hypothesis, as stated in his historical article "On the Electrodynamics of moving Bodies", we are led to the conclusion that the kinematics of a material point, as measured and described by a localized real-life Observer, always refers not to its present position but rather to the one it occupied at a previous moment in time, which we call Conjugate Position, or Retarded Position according to Richard Feynman. From the experimenter's point of view, only the Conjugate position is important. Thus, the moving entity is observed and measured at a position that is different to the one it occupies now, a conclusion eerily evocative of the "shadows" paradigm in Plato's Cave Allegory. This, i.e. the kinematics of the Conjugate Position, is analytically described by the "Theory of Harmonicity of the Field of Light". Having selected the Projective Space as its Geometrical space of choice, an important conclusion of this theory is that, for a localized Observer, a linearly moving object is possible to appear simultaneously at two different positions and, consequently, at two different states in the Observer's Perceptible Space. This conclusion leads to the formulation of at least two fundamental theorems as well as to a plethora of corollaries all in accordance with the notions of contemporary Quantum Mechanics. A new form of the Unified Field of Light is presented.

The universities of applied sciences (UAS) provide several values for the society and economy of a country. Besides education of high level professionals, transfer of knowledge from research to applications in industry or as new start-up companies is an important task. This is done in different ways in the various disciplines. In Life Sciences, a key industry branch in Switzerland, innovation is a competitive success factor and research findings from UAS/Life Sciences contribute to the valorization of new technologies to products, services and to business performance. In order to foster awareness for the innovation need of industry, UAS install processes and support for transfer of research and technology results to marketable applications. Furthermore they may facilitate contacts of researchers and students with entrepreneurs in order to animate start-up founding as a true alternative to being employed. Access to coaching and entrepreneurial training completes the essential basis.

European Meteorological Society and education in atmospheric sciences

Halenka, T.; Belda, M.

2010-09-01

EMS is supporting the exchange of information in the area of education in atmospheric sciences as one of its priority and organizing the educational sessions during EMS annual meetings as a good occasion for such an exchange. Brief thought will be given to the fate of the series of International Conferences on School and Popular Meteorological and Oceanographic Education - EWOC (Education in Weather, Ocean and Climate) and to the project oriented basis of further cooperation in education in atmospheric sciences across Europe. Another tool of EMS is the newly established and developed EDU portal of EMS. In most European countries the process of integration of education at university level was started after Bologna Declaration with the objective to have the system where students on some level could move to another school, or rather university. The goal is to achieve the compatibility between the systems and levels in individual countries to have no objections for students when transferring between the European countries. From this point of view EMS is trying to provide the information about the possibility of education in meteorology and climatology in different countries in centralised form, with uniform shape and content, but validated on national level. In most European countries the necessity of education in Science and Mathematics to achieve higher standard and competitiveness in research and technology development has been formulated after the Lisboa meeting. The European Meteorological Society is trying to follow this process with implication to atmospheric sciences. One of the important task of the EMS is the activity to promote public understanding of meteorology (and sciences related to it), and the ability to make use of it, through schools and more generally. One of the elements of EMS activity is the analysis of the position of atmospheric science in framework of curricula in educational systems of European countries as well as in more general sense, the place of Science education in the system.

Communicating Complex Sciences by Means of Exhibitions

NASA Astrophysics Data System (ADS)

Schneider, S.

2011-12-01

Earth Sciences will have to take over the leading role in global sustainable policy and in discussions about climate change. Efforts to raise attention within the politically responsible communities as well as in the public are getting more and more support by executive and advisory boards all over the world. But how can you successfully communicate complex sciences? For example, to start communication about climate change, the first step is to encourage people to be concerned about climate change. After that, one has to start thinking about how to present data and how to include the presented data into an unprejudiced context. Therefore, the communication toolbox offers various methods to reach diverse audiences. The R&D programme GEOTECHNOLOGIEN conducts roving exhibitions as one of its most successful communication tools. With roving exhibitions GEOTECHNOLOGIEN is able to get in touch with different audiences at once. The main purpose and theme of these exhibitions is to convey the everyday means of climate change to the visitors. It is within the responsibility of science to communicate the effects of a phenomenon like climate change as well as the impact of research results to the everyday life of people. Currently, a GEOTECHNOLOGIEN roving exhibition on remote sensing with satellites deals with various issues of environmental research, including a chapter on climate change. By following the 3M-concept (Meaning - Memorable - Moving), exhibitions allow to connect the visitors daily environment and personal experiences with the presented issues and objects. Therefore, hands-on exhibits, exciting multimedia effects and high-tech artefacts have to be combined with interpretive text elements to highlight the daily significance of the scientific topics and the exhibition theme respectively. To create such an exhibition, strong conceptual planning has to be conducted. This includes the specification of stern financial as well as time wise milestones. In addition, concepts to include professional techniques of science interpretation will become a crucial step on the way to success. The elements of successful exhibitions, tips for effective interpretive writing and display design as well as milestones in the exhibition planning process accompanied by ideas and recommendations to make your exhibition even more exciting, will be discussed. Framed by Anatole France's concept of successful interpretation and Freeman Tilden's definition of interpretation, this presentation will give you a new perspective on how to communicate climate change and other scientific topics.

Charlotte Moore Sitterly

NASA Astrophysics Data System (ADS)

Rubin, Vera C.

2010-07-01

Charlotte Moore Sitterly was a scientist in an era when it was rare for a woman to have the opportunity to devote her life to forefront science. Following her graduation from Swarthmore College in 1920, she accepted a position at Princeton University as an assistant to Henry Norris Russell. In 1925 she started a study of the solar spectrum. She could then not know that she would devote much of her scientific career to gathering basic atomic data that are invaluable to the scientific community, even today. In 1931 she obtained a Ph.D. degree at the University of California, Berkeley, and returned to Princeton as a staff member of the Princeton University Observatory. In 1945 Moore moved to the National Bureau of Standards (NBS), to supervise preparation of the widely-used tables of atomic energy levels. Following the successful launching (1946) of a V2 rocket to obtain the ultraviolet spectrum of the Sun, she started working also with Richard Tousey and his group at the Naval Research Laboratory (NRL). Ultimately, they extended the solar spectrum down to 2200 angstroms. She continued her affiliations with both the NBS and the NRL until her death in 1990. Charlotte Moore was a rare scientist who devoted her career to obtaining accurate numbers, thus enabling the scientific community to open her tables and know that the data are reliable.

A novel paradigm for cell and molecule interaction ontology: from the CMM model to IMGT-ONTOLOGY

PubMed Central

2010-01-01

Background Biology is moving fast toward the virtuous circle of other disciplines: from data to quantitative modeling and back to data. Models are usually developed by mathematicians, physicists, and computer scientists to translate qualitative or semi-quantitative biological knowledge into a quantitative approach. To eliminate semantic confusion between biology and other disciplines, it is necessary to have a list of the most important and frequently used concepts coherently defined. Results We propose a novel paradigm for generating new concepts for an ontology, starting from model rather than developing a database. We apply that approach to generate concepts for cell and molecule interaction starting from an agent based model. This effort provides a solid infrastructure that is useful to overcome the semantic ambiguities that arise between biologists and mathematicians, physicists, and computer scientists, when they interact in a multidisciplinary field. Conclusions This effort represents the first attempt at linking molecule ontology with cell ontology, in IMGT-ONTOLOGY, the well established ontology in immunogenetics and immunoinformatics, and a paradigm for life science biology. With the increasing use of models in biology and medicine, the need to link different levels, from molecules to cells to tissues and organs, is increasingly important. PMID:20167082

Moving beyond GK–12

Ufnar, J. A.; Kuner, Susan; Shepherd, V. L.

2012-01-01

The National Science Foundation GK–12 program has made more than 300 awards to universities, supported thousands of graduate student trainees, and impacted thousands of K–12 students and teachers. The goals of the current study were to determine the number of sustained GK–12 programs that follow the original GK–12 structure of placing graduate students into classrooms and to propose models for universities with current funding or universities interested in starting a program. Results from surveys, literature reviews, and Internet searches of programs funded between 1999 and 2008 indicated that 19 of 188 funded sites had sustained in-classroom programs. Three distinct models emerged from an analysis of these programs: a full-stipend model, in which graduate fellows worked with partner teachers in a K–12 classroom for 2 d/wk; a supplemental stipend model in which fellows worked with teachers for 1 d/wk; and a service-learning model, in which in-classroom activity was integrated into university academic coursework. Based on these results, potential models for sustainability and replication are suggested, including establishment of formal collaborations between sustained GK–12 programs and universities interested in starting in-classroom programs; development of a new Teaching Experience for Fellows program; and integration of supplemental fellow stipends into grant broader-impact sections.

As LSST moves toward construction and survey definition, the burden on the user community to begin planning and preparing for the massive data stream grows. In light of the significant challenge and opportunity that LSST now brings, a critical role for a National Observatory will be to advocate for, respond to, and advise the U.S. community on its use of LSST. NOAO intends to establish an LSST Community Science Center to meet these common needs. Such a Center builds on NOAO's leadership in offering survey-style instruments, proposal opportunities, and data management software over the last decade. This leadership has enabled high-impact scientific results, as evidenced by the award of the 2011 Nobel Prize in Physics for the discovery of Dark Energy, which stemmed directly from survey-style observations taken at NOAO. As steps towards creating an LSST Community Science Center, NOAO is 1) supporting the LSST Science Collaborations through membership calls and collaboration meetings; 2) developing the LSST operations simulator, the tool by which the community's scientific goals of are tested against the reality of what LSST's cadence can deliver; 3) embarking on a project to establish metrics for science data quality assessment, which will be critical for establishing faith in LSST results; 4) developing a roadmap and proposal to host and support the capability to help the community manage the expected flood of automated alerts from LSST; and 5) starting a serious discussion of the system capabilities needed for photometric and spectroscopic followup of LSST observations. The fundamental goal is to enable productive, world-class research with LSST by the entire US community-at-large in tight collaboration with the LSST Project, LSST Science Collaborations, and the funding agencies.

Keywords - Earth Science, data discovery, agile development, ruby on rails, catalog, OGC Audience - Earth Science application developers What is CwicStart CwicStart is a prototypical earth science data discovery web application designed, developed and hosted by NASA's Earth Observing System (EOS) Clearinghouse (ECHO). CwicStart searches the CEOS WGISS Integrated Catalog (CWIC) to provide users with dataset and granule level metadata from sources as diverse as NASA, NOAA, INPE and AOE. CwicStart demonstrates the ease of which it is possible to stand up a functioning client against the CWIC. From start to finish, CwicStart was designed, developed and deployed in one month. Built from OGC getCapabilities document of CWIC The CwicStart application takes the OGC getCapabilities (http://www.opengeospatial.org/standards/is) document describing CWIC, as it's starting point for providing a user interface suitable for interrogating CWIC. Consequently, it can allow the user to constrain their search by the following criteria, - Generic search terms - Spatial bounding box - Start date/time and end date/time - ISO-queryable key-value pairs User Interface inspired by Reverb ECHO's state-of-the-art earth science discovery tool, Reverb (http://reverb.echo.nasa.gov) was used as a guideline for the user interface components of CwicStart. It incorporates OpenLayers to provide point-and-click spatial constraint specification and calendar input for temporal constraints. Discovery involves two phases: dataset discovery and granule discovery with full pagination support for large results sets. CwicStart supports 'graceful degradation' of support for multiple browsers and accessibility requirements. Implemented in Ruby on Rails for Agile Development CwicStart is implemented in Ruby on Rails, a dynamic, rapid development language and environment that facilitates Agile development and is resilient to changing requirements. Using an Agile development methodology ECHO was able to stand up the first iteration of CwicStart in an iteration lasting only one week. Three subsequent week-long iterations delivered the current functionality. CwicStart can be found at the following location, https://testbed.echo.nasa.gov/cwic-start/ About CWIC The WGISS team provides an application, the CEOS WGISS Integrated Catalog (CWIC) with the following capabilities. - Provide an access point for major CEOS agency catalog systems. - Interface to user interface clients by using the GEO standards. - Send directory/collection searches to the International Directory Network. - Distribute inventory/product searches to the CEOS agency inventory systems using the agency systems native protocol. - Offered as the CEOS community catalog as part of the GEO common infrastructure.

Digital innovation, introduced across many industries, is a strong force of transformation. Some industries have seen faster transformation, whereas the health care sector only recently came into focus. A context where digital corporations move into health care, payers strive to keep rising costs at bay, and longer-living patients desire continuously improved quality of care points to a digital and value-based transformation with drastic implications for the health care sector. We tried to operationalize the discussion within the health care sector around digital and disruptive innovation to identify what type of technological enablers, business models, and value networks seem to be emerging from different groups of innovators with respect to their digital transformational efforts. From the Forbes 2000 and CBinsights databases, we identified 100 leading technology, life science, and start-up companies active in the health care sector. Further analysis identified projects from these companies within a digital context that were subsequently evaluated using the following criteria: delivery of patient value, presence of a comprehensive and distinctive underlying business model, solutions provided, and customer needs addressed. Our methodological approach recorded more than 400 projects and collaborations. We identified patterns that show established corporations rely more on incremental innovation that supports their current business models, while start-ups engage their flexibility to explore new market segments with notable transformations of established business models. Thereby, start-ups offer higher promises of disruptive innovation. Additionally, start-ups offer more diversified value propositions addressing broader areas of the health care sector. Digital transformation is an opportunity to accelerate health care performance by lowering cost and improving quality of care. At an economic scale, business models can be strengthened and disruptive innovation models enabled. Corporations should look for collaborations with start-up companies to keep investment costs at bay and off the balance sheet. At the same time, the regulatory knowledge of established corporations might help start-ups to kick off digital disruption in the health care sector. ©Maximilian Herrmann, Philip Boehme, Thomas Mondritzki, Jan P Ehlers, Stylianos Kavadias, Hubert Truebel.

We report results of a direct imaging survey for giant planets around 80 members of the β Pic, TW Hya, Tucana-Horologium, AB Dor, and Hercules-Lyra moving groups, observed as part of the Gemini/NICI Planet-Finding Campaign. For this sample, we obtained median contrasts of ΔH = 13.9 mag at 1'' in combined CH4 narrowband ADI+SDI mode and median contrasts of ΔH = 15.1 mag at 2'' in H-band ADI mode. We found numerous (>70) candidate companions in our survey images. Some of these candidates were rejected as common-proper motion companions using archival data; we reobserved with Near-Infrared Coronagraphic Imager (NICI) all other candidates that lay within 400 AU of the star and were not in dense stellar fields. The vast majority of candidate companions were confirmed as background objects from archival observations and/or dedicated NICI Campaign followup. Four co-moving companions of brown dwarf or stellar mass were discovered in this moving group sample: PZ Tel B (36 ± 6 M Jup, 16.4 ± 1.0 AU), CD-35 2722B (31 ± 8 M Jup, 67 ± 4 AU), HD 12894B (0.46 ± 0.08 M ⊙, 15.7 ± 1.0 AU), and BD+07 1919C (0.20 ± 0.03 M ⊙, 12.5 ± 1.4 AU). From a Bayesian analysis of the achieved H band ADI and ASDI contrasts, using power-law models of planet distributions and hot-start evolutionary models, we restrict the frequency of 1-20 M Jup companions at semi-major axes from 10-150 AU to <18% at a 95.4% confidence level using DUSTY models and to <6% at a 95.4% using COND models. Our results strongly constrain the frequency of planets within semi-major axes of 50 AU as well. We restrict the frequency of 1-20 M Jup companions at semi-major axes from 10-50 AU to <21% at a 95.4% confidence level using DUSTY models and to <7% at a 95.4% using COND models. This survey is the deepest search to date for giant planets around young moving group stars.

Radar Shows Italy Area Moved 8 Inches by Amatrice Earthquake

NASA Image and Video Library

2016-08-27

NASA and its partners are contributing observations and expertise to the ongoing response to the Aug. 23, 2016, magnitude 6.2 Amatrice earthquake in central Italy caused widespread building damage to several towns throughout the region. This earthquake was the strongest in that area since the 2009 earthquake that destroyed the city of L'Aquila. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory, Pasadena, California, and the California Institute of Technology in Pasadena, analyzed interferometric synthetic aperture radar images from the PALSAR-2 instrument on the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) to calculate a map of the deformation of Earth's surface caused by the quake. This false-color map shows the amount of permanent surface movement, as viewed by the satellite, during a seven-month interval between two ALOS-2 images acquired on Sept. 9, 2015 and Aug. 24, 2016. The movement was caused almost entirely by the earthquake. In this map, the colors of the surface displacements are proportional to the surface motion. The red and pink tones show the areas where the land moved toward the satellite by up to 2 inches (5 centimeters). The area with various shades of blue moved away from the satellite, mostly downward, by as much as 8 inches (20 centimeters). Contours on the surface motion are 2 inches (5 centimeters) The green star shows the epicenter where the earthquake started as located by the U.S. Geological Survey National Earthquake Information Center. Black dots show town locations. Scientists use these maps to build detailed models of the fault slip at depth and associated land movements to better understand the impact on future earthquake activity. The map shows the fault or faults that moved in the earthquake is about 14 miles (22 kilometers) long between Amatrice and Norcia and slopes to the west beneath the area that moved downward. The PALSAR-2 data were provided by JAXA through a science project. http://photojournal.jpl.nasa.gov/catalog/PIA20893

Science and thinking: The write connection

NASA Astrophysics Data System (ADS)

Butler, Gene

1991-09-01

The effective use of writing in science instruction may open the way for students to grow in their ability to exercise higher order thinking skills (Bland & Koppel, 1988). Scinto (1986) makes a compelling case for writing as a means of stimulating thinking when he states: The production of written text demands more elaborate strategies of preplanning. Written language demands the conscious organization of ensembles of propositions to achieve its end. The need to manipulate linguistic means in such a conscious and deliberate fashion entails a level of linguistic self-reflection not called forth in oral discourse (p. 101). Science educators may find that the writing process is one technique to help them move away from the teacher-centered, textbook-driven science classroom of today, and move toward the realization of science education which will ensure that students are able to function as scientifically literate citizens in our contemporary society.

Moving Closer to EarthScope: A Major New Initiative for the Earth Sciences*

NASA Astrophysics Data System (ADS)

Simpson, D.; Blewitt, G.; Ekstrom, G.; Henyey, T.; Hickman, S.; Prescott, W.; Zoback, M.

2002-12-01

EarthScope is a scientific research and infrastructure initiative designed to provide a suite of new observational facilities to address fundamental questions about the evolution of continents and the processes responsible for earthquakes and volcanic eruptions. The integrated observing systems that will comprise EarthScope capitalize on recent developments in sensor technology and communications to provide Earth scientists with synoptic and high-resolution data derived from a variety of geophysical sensors. An array of 400 broadband seismometers will spend more than ten years crossing the contiguous 48 states and Alaska to image features that make up the internal structure of the continent and underlying mantle. Additional seismic and electromagnetic instrumentation will be available for high resolution imaging of geological targets of special interest. A network of continuously recording Global Positioning System (GPS) receivers and sensitive borehole strainmeters will be installed along the western U.S. plate boundary. These sensors will measure how western North America is deforming, what motions occur along faults, how earthquakes start, and how magma flows beneath active volcanoes. A four-kilometer deep observatory bored directly into the San Andreas fault will provide the first opportunity to observe directly the conditions under which earthquakes occur, to collect fault rocks and fluids for laboratory study, and to monitor continuously an active fault zone at depth. All data from the EarthScope facilities will be openly available in real-time to maximize participation from the scientific community and to provide on-going educational outreach to students and the public. EarthScope's sensors will revolutionize observational Earth science in terms of the quantity, quality and spatial extent of the data they provide. Turning these data into exciting scientific discovery will require new modes of experimentation and interdisciplinary cooperation from the Earth science community. A broad sector of the university research community has joined with federal agencies to stimulate the development of facility plans and move EarthScope forward as a coordinated national initiative. With strong prospects for funding next year, the time is right for bold new ideas on how to maximize the use of these powerful new resources in the Earth scientist's toolkit. * On behalf of the EarthScope Working Group

After having written hundreds of research articles, reviews, and book chapters, I find it awkward to pen an autobiography. I still do use a pen. As stated by others in the nutrition field who have written of their own experiences in a perspective article for the Annual Review of Nutrition, my course through this field of science has been serendipitous. My interest in nutrition developed during my experiences with horses and then Angus cattle and entry into an animal science degree program. As the age of molecular biology was unfolding, I pursued a PhD in nutritional biochemistry with Hamilton Eaton at the University of Connecticut followed by postdoctoral work with Hector DeLuca at the University of Wisconsin, working on vitamins A and D, respectively. At Rutgers University, one of the two institutions where I have served on the faculty, I started my research program on trace elements with a focus on cadmium toxicity but soon thereafter began my research on zinc metabolism and function. I moved to the University of Florida in 1982 for an endowed position and have been a Florida Gator ever since. At the University of Florida, research expanded to include identification of zinc-responsive genes and physiological outcomes of zinc transport influencing health and disease, particularly as related to inflammation. I had the opportunity to contribute national science policy as president of both the Federation of American Societies for Experimental Biology and the American Society for Nutrition. As the time of this writing, I maintain an active laboratory.

Teams of scientists representing diverse disciplines are often brought together for purposes of better understanding and, ultimately, resolving urgent public health and environmental problems. Likewise, the emerging field of the science of team science draws on diverse disciplinary perspectives to better understand and enhance the processes and outcomes of scientific collaboration. In this supplement to the American Journal of Preventive Medicine, leading scholars in the nascent field of team science have come together with a common goal of advancing the field with new models, methods, and measures. This summary article highlights key themes reflected in the supplement and identifies several promising directions for future research organized around the following broad challenges: (1) operationalizing cross-disciplinary team science and training more clearly; (2) conceptualizing the multiple dimensions of readiness for team science; (3) ensuring the sustainability of transdisciplinary team science; (4) developing more effective models and strategies for training transdisciplinary scientists; (5) creating and validating improved models, methods, and measures for evaluating team science; and (6) fostering transdisciplinary cross-sector partnerships. A call to action is made to leaders from the research, funding, and practice sectors to embrace strategies of creativity and innovation in a collective effort to move the field forward, which may not only advance the science of team science but, ultimately, public health science and practice.

For the needs of the 21st century, the Government of Malaysia has conceptualized the Malaysia Education Blueprint 2013-2025 which embodies 11 strategic and operational shifts. In Shift 1, it is emphasized that the quality of Science, Technology, Engineering, and Mathematics (STEM) Education will be enhanced. This study employed the mixed-method approach using the “one-group pre-test and post-test design”. Accordingly, this paper describes the pedagogical practice of Project-based Inquiry Learning (PIL) which promotes STEM Education among Year 1 students in the move to progress in tandem with Shift 1. Specifically, using the context of a magnet which has been stipulated in the Primary School Standard Curriculum, Year 1 students experienced the STEM Education through the STEM Pedagogy in which they raised questions upon the presentation of a relevant stimulus (Inquiry Phase), explored the ways in which a train carriage or coach could be assembled by means of recycled materials and magnets (Exploration Phase), designed a train carriage (Design Phase), and ultimately reflected on their inventions (Reflection Phase). The cognitive and affective impacts through the use of this Project-based Inquiry Learning are presented. Implications for the teaching and learning of science are discussed within the context of STEM Education.

The start of the Japanese Venus Exploration program was in 2001, and last year (2006) we moved it to Phase C after PDR in August.We would like to report the present status of our Venus Climate Orbiter. Planet-C is the project name in ISAS/JAXA. The launch vehicle is changed from M-V to H-IIA. It will be launched from Tanegashima Space Center (TNSC) in Kagoshima. With this modification, we changed some minor design of the spacecraft and the total weight is slightly heavier than before, but the basic design has not been modified. The launch window will be kept in summer in 2010 and it will arrive at Venus in December 2010. The spacecraft will be directly put into the interplanetary orbit. Now we are preparing the Mechanical and Thermal engineering Model (MTM) which will end in middle of 2007 and will shake it and do the thermal vacuum test. Later this model will be modified to the flight model and the final integration test will be in 2009 which takes 1 year. Development of all the science instruments are going well. The first integration test of science instruments will be in August this year. We can report the results of it in the meeting.

Poisson's ratio over two centuries: challenging hypotheses

PubMed Central

Greaves, G. Neville

2013-01-01

This article explores Poisson's ratio, starting with the controversy concerning its magnitude and uniqueness in the context of the molecular and continuum hypotheses competing in the development of elasticity theory in the nineteenth century, moving on to its place in the development of materials science and engineering in the twentieth century, and concluding with its recent re-emergence as a universal metric for the mechanical performance of materials on any length scale. During these episodes France lost its scientific pre-eminence as paradigms switched from mathematical to observational, and accurate experiments became the prerequisite for scientific advance. The emergence of the engineering of metals followed, and subsequently the invention of composites—both somewhat separated from the discovery of quantum mechanics and crystallography, and illustrating the bifurcation of technology and science. Nowadays disciplines are reconnecting in the face of new scientific demands. During the past two centuries, though, the shape versus volume concept embedded in Poisson's ratio has remained invariant, but its application has exploded from its origins in describing the elastic response of solids and liquids, into areas such as materials with negative Poisson's ratio, brittleness, glass formation, and a re-evaluation of traditional materials. Moreover, the two contentious hypotheses have been reconciled in their complementarity within the hierarchical structure of materials and through computational modelling. PMID:24687094

Life Sciences Start-ups in Switzerland: CTI and its Support for Young Entrepreneurs.

2014-12-01

According to the Global Entrepreneurship Monitor 2013, perceived opportunities to start a business in Switzerland are high and rank above average compared to other innovation-based countries. 2013 was a record year for start-ups in Switzerland. Around 40,000 new businesses were recorded in the commercial register and the trend is set to continue. There are two main criteria that lead to success, particularly for science- or technology- based start-ups: first of all, it is the business or product idea itself, and secondly it is the entrepreneurial team. CTI is supporting innovation in a manner that responds to a need in the market identified by industry.

Examining how youth of color engage youth participatory action research to interrogate racism in their science experiences

NASA Astrophysics Data System (ADS)

Sato, Takumi C.

While many researchers have worked to address the unequal educational outcomes between White and non-White students, there are few signs of progress for people of color seeking entry into a STEM career trajectory. Starting from high school, the number of students who persist to complete a STEM bachelor's degree and obtaining a job in science or engineering continues to indicate that people of color are underrepresented. I suggest that research must consider the role of race and racism in the education of youth of color. Especially in science education, there is very little work addressing how racism may present barriers that impede progress for students along the STEM trajectory. This study is informed by critical race theory (CRT) that posits racism is endemic in society. White privilege enables the dominant group to maintain inequitable advantages that marginalizes populations of color. CRT also puts forth that counter narratives of the marginalized groups is essential to challenge the institutionalized forms of oppression. Using CRT and youth participatory action research (YPAR), this investigation re-imagines youth as capable of transforming their own social and political condition through research and action. This project asked youth of color to interrogate their own experiences as science learners, engage in research on structural inequities of STEM trajectories, plan strategic moves to challenge power structures, and take action for social justice. The youth started by exploring the concept of race and instances where racism was found in public spaces and in their personal experiences. They examined their experiences in science as a student more generally and then for racism. Then, the focus turned to conducting research with peers, observing science classrooms in another school, and using online information to compare schools. The youth planned strategic action against the racism they found in the analysis of the data that included conference presentations, using social media to communicate with peers, and teaching a science unit for middle grades peers using lessons that incorporated engaging teaching practices lacking in their student experiences. YPAR resulted in counternarratives that exposed youth encounters with systemic racism and their efforts to positively change STEM trajectories for themselves and their peers. Through YPAR, youth gained research tools and skills to critically examine the world and expose racism. While schools are purported to be places of equal opportunity for all students to learn and find success, the youth showed that institutionalized racism in schools created barriers to STEM aspirations. By planning and teaching a food and nutrition unit, the youth took aim at the institutionalized racism by taking on the role of teacher and expert while improving the science learning opportunities for their middle grades peers and themselves. In addition, planning the unit enabled the youth to conduct all of the activities before teaching the unit. Thus, the youth supplemented their own science learning. YPAR provided an empowering opportunity to challenge racism along their STEM trajectories and fight for social justice.

The design procedure for moving coil type linear generator starts from the rated power imposed and finally uses the Faraday law of induction. The magneto-static magnetic field generated by permanent magnets is analyzed by means of Reluctance method and Finite Element Method in order to evaluate the magnetic flux density in the air gap, which is a design data imposed in the design stage, and the results are compared.

Framing the Mind-Body Problem in Contemporary Neuroscientific and Sunni Islamic Theological Discourse.

PubMed

Qazi, Faisal; Fette, Don; Jafri, Syed S; I Padela, Aasim

2018-07-01

Famously posed by seventeenth-century French philosopher René Descartes, the mind-body problem remains unresolved in western philosophy and science, with both disciplines unable to move convincingly beyond the dualistic model. The persistence of dualism calls for a reframing of the problem through interdisciplinary modes of inquiry that include non-western points of view. One such perspective is Islamic theology of the soul, which, while approaching the problem from a distinct point of view, also adopts a position commensurate with (substance) dualism. Using this point of convergence as a conceptual starting point, we argue that bringing into dialogue contemporary neuroscientific, philosophy of mind, and Sunni Islamic theological discourses may provide a fruitful way of reframing the age-old mind-body problem. This paper provides an overview of how these three discourses have approached the issue of the mind-body (-soul) problem. Juxtaposing these three discourses, we hope, may ignite further scholarly dialogue and investigation.

2017-01-01

Based on the experience from Prototype Imaging Spectrograph for Coronagraphic Exoplanet Studies (PISCES) for WFIRST, we have moved to the flight instrument design phase. The specifications for flight IFS have similarities and differences from the prototype. This paper starts with the science and system requirement, discusses a number of critical trade-offs: such as IFS type selection, lenslet array shape and layout versus detector pixel accuracy, how to accommodate the larger Field Of View (FOV) and wider wavelength band for a potential add-on StarShade occulter. Finally, the traditional geometric optical design is also investigated and traded: reflective versus refractive, telecentric versus non-telecentric relay. The relay before the lenslet array controls the chief angle distribution on the lenslet array. Our previous paper has addressed how the relay design combined with lenslet arraypinhole mask can further compress the residual star light and increase the contrast. Finally, a complete phase A IFS optical design is presented.

Nineteen ninety-eight has been a transition year for Engineering, as we have moved from our traditional focus on thrust areas to a more focused approach with research centers. These five new centers of excellence collectively comprise Engineering's Science and Technology program. This publication summarizes our formative year under this new structure. Let me start by talking about the differences between a thrust area and a research center. The thrust area is more informal, combining an important technology with programmatic priorities. In contrast, a research center is directly linked to an Engineering core technology. It is the purer model, for itmore » is more enduring yet has the scope to be able to adapt quickly to evolving programmatic priorities. To put it another way, the mission of a thrust area was often to grow the programs in conjunction with a technology, whereas the task of a research center is to vigorously grow our core technologies. By cultivating each core technology, we in turn enable long-term growth of new programs.« less

Galileo as an intellectual heretic and why that matters

NASA Astrophysics Data System (ADS)

Palmieri, Paolo

2014-03-01

What was physics like before Galileo? Five centuries ago physics was taught in universities all over Europe as part of a broader field of knowledge known as natural philosophy. It was neither quantitative, nor experimental, but mostly an a-priori, logical type of inquiry about principles concerning notions such as space, time, and motion, from which deductions could be made about the natural world. Galileo changed all that. He claimed that inquiry about nature should be experimental, and that reasoning in natural philosophy should be mathematical. It was a bold enough move. But Galileo's intellectual heresy was the discovery that knowledge of the natural world could only be achieved by relaxing the requirement that principles be known with absolute certainty. He demonstrated that a new mathematical physics could be built upon principles based on experiment. Thus the new physics could be extended recklessly by starting from less than certain foundations. Galileo's startling insight was that scientific truth need not be localized but can be diffused throughout the structure of science.

Role Models for boosting mobility of women scientists in geosciences

NASA Astrophysics Data System (ADS)

Avellis, Giovanna; Theodoridou, Magdalini

2017-04-01

More and more women today are choosing to study science and undertake scientific careers. Likewise mobility during one's career is increasingly important as research tends to be undertaken via international collaboration, often within networks based on the researchers mobility, especially in geosciences. We have developed an ebook on Role Models for boosting mobility of women scientists to showcase the careers of women scientists who have undertaken mobility during their careers. It is hoped that their stories will provide young women who are just starting out in their science careers with inspirational role models, and that these stories give them realistic information about career opportunities: many of them are women scientists in geosciences. These are not famous scientists, but rather real examples of people who express all the passion of the world of science. It is hoped that reading about successful scientists who have achieved a healthy work-life balance while moving to new locations will be particularly helpful for those individuals considering mobility in their own career. The ebook is available to be used by programs that support the development of systematic approaches to increasing the representation and advancement of women in science, engineering and technology, since mobility plays a key role in these programs. The stories contained herein will be useful to mentoring or advising program focusing on career, networking opportunities, discussion and grants opportunities in conjunction with mobility. There is still a gap between female graduates and the pool of female job applicants - even though the proportion of female graduate students and postdocs in most scientific fields is higher today than it is ever been. Therefore we suggest that focus should be placed on examining the real challenges which women need to overcome, particularly when "mobility" comes into play. Role models who have overcome these challenges will continue to play an important part in moving in the right direction, because it may take some time to achieve true gender equity in science. The MCAA is committed to the promotion of women scientists and is sensitive to gender issues in science, and thus a Women in Science working group has been established, namely the Gender Equality for Mobile researchers in Science (GEMS). The GEMS working group has been active since September 2014 in order to promote mobility among the women scientists community, provide feedback from the European Community on policy issues regarding mobility in particular, and to collaborate with other associations and organizations active in the same fields. The main goal is to find ways to promote the participation of and motivation for women with regard to science and therefore finding and analyzing reasons why women face problems or give up at the high levels of the science field. The WG GEMS has participated in WiS conferences at the European level and outside of it, including Gender Summit, WIRES, MARIE CURIE CONFERENCES, ESOF2016, and are also applying to HORIZON2020 to study different types of researchers' mobility, such as virtual mobility, Intersectoral mobility between industry and academia, interdisciplinary mobility, and others.

Reinventing the role of consumer research in today's open innovation ecosystem.

PubMed

Moskowitz, Howard R; Saguy, I Sam

2013-01-01

Consumer research (CR) has played a key role in the food and beverage industry. Emerging from laboratory product-tests, it has evolved into a corporate testing service that measures the consumer reactions to products/concepts using a wide range of analyses/metrics. We propose that CR transform itself in light of accelerated knowledge expansion, mounting global, and local economic pressure on corporations and changing consumer needs. The transformation moves from its traditional testing into creating profoundly new knowledge of the product and understanding of the corporation's current and future customers. CR's tasks will involve: contributing/expanding science, applying open innovation principles, and driving consumer-centric innovation. We identify seven paradigm shifts that will change CR, namely: a different way of working--from testing to open sourcing; from good corporate citizen to change leader; open new product development (NPD) process; new management roles/cultures; universities and industry, new education curricula, and cooperation; from battle over control to sustainable sharing is winning model (SiW); and the central role of design. This integrative, innovative CR requires the implementation of three recommendations: start the change process now, fine-tune along the way; create a new marketing/CR department; and educate and professionalize. These recommendations provide the blueprint for jump-starting the process and call for immediate actions to deal with the severity of the crises facing the CR profession.

Towards a well-connected, global, interdisciplinary research community for rational decision making in the Anthropocene

NASA Astrophysics Data System (ADS)

Rauser, Florian

2016-04-01

The Young Earth System Scientists community YESS (yess-community.org) is a global network of Earth System Science early career researchers focussing on interdisciplinarity. One of the central goals of our early career network is to communicate to the world that Earth System Science has accepted the central challenge of creating tangible products for the benefit of society. A coordinated and truly global approach to Earth System Science is our best attempt to focus our understanding of the complex interplay of Earth's processes into tools for future societies, i.e., for humanity to move away from being a sorcerer's apprentice and to become a rational actor. We believe that starting with the next generation of Earth system scientists to work on that unified approach and creating an environment that allows ambitious, forward-thinking, interdisciplinary science to blossom will be our best way forward into a mature Anthropocene. In 2015 YESS started a process to come up with a definition of the Frontiers of Earth System Science research from an early career perspective, together with the research arms of the World Meteorological Organisation (WMO). During this process it became apparent that there are a few major aspects that cannot be put into the forefront often enough: one, the reality of capacity building; societies can only have robust decision-making if their decision makers can be advised not only by global assessment processes like the Intergovernmental Panel on Climate Change (IPCC) but also by local experts. The reality of a globalised science community is often only true for a few scientists at the very top from a selected number of countries. Two, the integration and balance of both user-driven and fundamental research is key to make science one pillar of a global, mature Anthropocene. This includes a better way to communicate science to end users and a more comprehensive homogenisation of weather and climate research agendas. Three, a complete overview of the scales of predictability and control of the Earth system has to be developed and maintained as a basis of societal decision making. Four, the interdisciplinary research that is required for better understanding the Anthropocene requires global research coordination across fields that is currently not necessarily reflected in standing research organisation structures. Five, the necessity of better integration of science into societal decision processes. The 2015 Conference of the Parties 21 in Paris has shown what is possible on a global, aggregated policy level - but the next years will have to show which societal actors can be thought of as rational and deliberate. This point addresses the issue that science alone is not the rational actor we need in the future, but can only advise those actors. In this session we want to outline those arguments with examples and discuss the influence of a global research funding structure that often reflects what we did in the past more, than what we want to do in the future. This discussion includes an example of the concept of science based target setting, a methodology developed to transfer scientific information into guidelines for companies.

Strengthening and Fostering Science and Technology Programs in Latinamerica and the Caribbean

NASA Astrophysics Data System (ADS)

Fucugauchi, J. U.

2013-05-01

An overview and discussion of the status of research and education in Latinamerica and the Caribbean is used for developing a proposal for a research foundation or agency in the region and establishing initiatives for capacity building and promoting and strengthening scientific programs and cooperation. Scientific research increasingly requires global multi- and inter-disciplinary approaches and infrastructure. Developing countries face challenges resulting from small academic communities, limited economic resources, and pressing social and political issues. Science and education are not major priorities as compared with more pressing issues related to poverty, diseases, conflicts, drugs and famine. However, solving major problems require improved educational and research programs. International research collaboration, north-south and south-south, has an immense potential, but basic infrastructure and internal organization at national and regional levels are required. For the analysis we concentrate on current situation, size and characteristics of research community, education programs, facilities, economic support, and bilateral and multinational collaborations. Analysis also includes the São Paulo Research Foundation (FAPESP) and the Yucatan Science and Technology System (SIIDETEY). FAPESP is a highly successful public foundation started more than 50 years ago, dedicated to foster scientific and technological development in the State of São Paulo and which has had a major impact in Brazil. SIIDETEY is a more recent effort of the Yucatan Government, also dedicated to support research and technology innovation within the state. We then move to discussion on perspectives for future development and capacity building in regional and international contexts, including international collaboration programs. We propose to establish a Science Foundation for the Latinamerica and Caribbean and develop an agenda for strengthening scientific programs in the region.

Just being on the Internet is Old News

E-Gov is an idea that is very popular these days. Many government agencies are adopting electronic information technology to improve both their internal and external capabilities to communicate with stakeholders and customers. This is an area where the Internet offers huge improvements in responsiveness. Unfortunately, Internet outreach traditionally has not been a budget area that received strong support in most agencies. Today, almost every government agency has some Internet presence: some extensive; others minimal. However, if you really want to reach your stakeholders and customers, just putting information out is not enough to assure it is useful. The most effective outreach sites are those that have moved beyond first generation static designs and concepts to newer communications approaches that stress two-way communication and collection and analysis of customer-oriented performance metrics. This talk discusses a few basic concepts in customer/stakeholder interaction as practiced by the very successful NASA family of websites, Science@NASA. Started 7 years ago as a single website, focusing on the science output of the Space Science Lab at NASA's Marshall Space Flight Center, Science@NASA in 2002 consisted of 6 websites with 450,000 subscribers and garnered over 700 million hits (approx. 64 million visits) in 2002 plus 3 international awards in the past 3 years. Focused content, tying presentation techniques to advanced communications concepts, managing and soliciting subscribers lists, automatic collection of performance metrics, soliciting and responding to customer feedback, and subscriber surveys are among the topics to be discussed. The successful NASAKids Club and the interactivity offered to children will also be covered. The attempt to make the customer/stakeholder DO SOMETHING is critical to our success.

It's not maths; it's science: exploring thinking dispositions, learning thresholds and mindfulness in science learning

NASA Astrophysics Data System (ADS)

Quinnell, R.; Thompson, R.; LeBard, R. J.

2013-09-01

Developing quantitative skills, or being academically numerate, is part of the curriculum agenda in science teaching and learning. For many of our students, being asked to 'do maths' as part of 'doing science' leads to disengagement from learning. Notions of 'I can't do maths' speak of a rigidity of mind, a 'standoff', forming a barrier to learning in science that needs to be addressed if we, as science educators, are to offer solutions to the so-called 'maths problem' and to support students as they move from being novice to expert. Moving from novice to expert is complex and we lean on several theoretical frameworks (thinking dispositions, threshold concepts and mindfulness in learning) to characterize this pathway in science, with a focus on quantitative skills. Fluid thinking and application of numeracy skills are required to manipulate experimental data sets and are integral to our science practice; we need to stop students from seeing them as optional 'maths' or 'statistics' tasks within our discipline. Being explicit about the ways those in the discipline think, how quantitative data is processed, and allowing places for students to address their skills (including their confidence) offer some ways forward.

Chess Revision: Acquiring the Rules of Chess Variants through FOL Theory Revision from Examples

NASA Astrophysics Data System (ADS)

Muggleton, Stephen; Paes, Aline; Santos Costa, Vítor; Zaverucha, Gerson

The game of chess has been a major testbed for research in artificial intelligence, since it requires focus on intelligent reasoning. Particularly, several challenges arise to machine learning systems when inducing a model describing legal moves of the chess, including the collection of the examples, the learning of a model correctly representing the official rules of the game, covering all the branches and restrictions of the correct moves, and the comprehensibility of such a model. Besides, the game of chess has inspired the creation of numerous variants, ranging from faster to more challenging or to regional versions of the game. The question arises if it is possible to take advantage of an initial classifier of chess as a starting point to obtain classifiers for the different variants. We approach this problem as an instance of theory revision from examples. The initial classifier of chess is inspired by a FOL theory approved by a chess expert and the examples are defined as sequences of moves within a game. Starting from a standard revision system, we argue that abduction and negation are also required to best address this problem. Experimental results show the effectiveness of our approach.

Epicrania Fugax is a paroxysmal, short-lasting, head pain moving across one hemicranium, describing a linear or zag trajectory, starting and ending in territories of different nerves. Between attacks, patients are usually free of symptoms. We describe an Epicrania Fugax patient complaining of interictal pain. The interictal pain was line-shaped and extended across the usual starting and ending points of the typical Epicrania Fugax paroxysms. Although rarely encountered, persistent linear pain may be a feature of Epicrania Fugax.

NESTA Revolutionizing Teacher's Experiences at NSTA Conventions

NASA Astrophysics Data System (ADS)

Ireton, F.

2002-05-01

National Science Teachers Association (NSTA) conventions are traditionally composed of short workshops, half or full day workshops, and lectures on science teaching or education research. Occasional science lectures such as the AGU lecture offer science content information. The National Earth Science Teachers Association (NESTA) will join the National Association of Geoscience Teachers (NAGT), American Geophysical Union (AGU), and the American Geological Institute (AGI) to bring teachers a suite of exciting and informative events at the (NSTA) 2002 convention. Events begin with a guided learning field trip to Mission Trails Regional Park and Torrey Pines State Reserve where Earth and space science teachers experience a model of constructivist leaning techniques. Most field trips are a "show and tell" experience, designed to transmit knowledge from the field trip leader to the field trip participants. In the "guided learning" environment, the leader serves as a facilitator, asking questions, guiding participants to discover concepts for themselves. Participants examine selected processes and features that constitute a constructivist experience in which knowledge acquired at any given location builds on knowledge brought to the site. Employing this strategy involves covering less breadth but greater depth, modeling the concept of "less is more." On Thursday NESTA will host two Share-a-thons. These are not what a person would think of as a traditional workshop where presenter makes a presentation then the participants work on an activity. They could be called the flea market of teaching ideas. Tables are set around the perimeter of a room where the presenters are stationed. Teachers move from table to table picking up information and watching short demonstrations. The Earth and Space Science Resource Day on Friday will focus on teachers needs. Starting with breakfast, teachers will hear from Soames Summerhays, Naturalist and President of Summerhays Films, about how he works science and education into the making of IMAXr films. After breakfast, NESTA and NAGT members team up for a joint Share-a-thon. Three AGU sponsored scientists discussing their research follow the Share-a-thon. These presentations are designed to provide teachers with up-to-date content information. A highlight of the day will be the NESTA rock raffle of over 100 specimens.

Validating concepts of mental disorder: precedents from the history of science.

PubMed

Miller, Robert

2014-10-01

A fundamental issue in any branch of the natural sciences is validating the basic concepts for use in that branch. In psychiatry, this issue has not yet been resolved, and indeed, the proper nature of the problem has scarcely been recognised. As a result, psychiatry (or at least those parts of the discipline which aspire to scientific status) still cannot claim to be a part of scientific medicine, or to be incorporated within the common language of the natural sciences. While this creates difficulties within the discipline, and its standing in relation to other branches of medicine, it makes it an exciting place for "frontiersmen" (and women). This is one of the key growing points in the natural science tradition. In this essay, which moves from the early history of that tradition to today's debates in scientific psychiatry, I give my views about how these fundamental issues can move towards resolution.

Toward a science of morality: response to Christian Miller's critique.

In developing a science of morality, many examples are provided not only to document the moral progress that has been made over the centuries, but also the reasons why and how this progress has been made. Instead of moralizing about human action and social problems that we find deplorable or undesirable, ever since the Scientific Revolution and the Enlightenment we started seeing them as problems to be solved. A science of morality begins with the discovery of rights and other moral values and emotions, starting with the recognition of the individual as an autonomous moral agent with an evolved natural desire to survive and flourish. © 2016 New York Academy of Sciences.

Angry Birds in Space

NASA Astrophysics Data System (ADS)

Halford, A. J.

2017-12-01

When space computers first started listening into space radio, they noticed that there were radio noises that happened on the morning side of the Earth. Because these waves sounded like noises birds make in the morning, we named these waves after them. These bird sounding waves can move around the Earth, flying up and down, and sometimes move into an area where there is more stuff. This area is also much colder than where these bird noises are first made. When the waves move into this cold area where there is more stuff, they start to sound like angry birds instead of happy birds. Both of these waves, the happy and angry bird sounding waves, are very important to our understanding of how the tiny things in space move and change. Sometimes the waves which sound like birds can push these tiniest of things into the sky. The happy bird sounding waves can push the tiniest things quickly while the angry bird sounding waves push the tinest of things more slowly. When the tiny things fall into the sky, they create beautiful space lights and light that burns which can hurt people in up goers and not so up goers as well as our things like phones, and space computers. We study these waves that sound like birds to better understand when and where the tiny things will fall. That way we can be prepared and enjoy watching the pretty space lights at night with no worries.

Cool-down and frozen start-up behavior of a grooved water heat pipe

NASA Technical Reports Server (NTRS)

Jang, Jong Hoon

1990-01-01

A grooved water heat pipe was tested to study its characteristics during the cool-down and start-up periods. The water heat pipe was cooled down from the ambient temperature to below the freezing temperature of water. During the cool-down, isothermal conditions were maintained at the evaporator and adiabatic sections until the working fluid was frozen. When water was frozen along the entire heat pipe, the heat pipe was rendered inactive. The start-up of the heat pipe from this state was studied under several different operating conditions. The results show the existence of large temperature gradients between the evaporator and the condenser, and the moving of the melting front of the working fluid along the heat pipe. Successful start-up was achieved for some test cases using partial gravity assist. The start-up behavior depended largely on the operating conditions.

Control Program for an Optical-Calibration Robot

NASA Technical Reports Server (NTRS)

Johnston, Albert

2005-01-01

A computer program provides semiautomatic control of a moveable robot used to perform optical calibration of video-camera-based optoelectronic sensor systems that will be used to guide automated rendezvous maneuvers of spacecraft. The function of the robot is to move a target and hold it at specified positions. With the help of limit switches, the software first centers or finds the target. Then the target is moved to a starting position. Thereafter, with the help of an intuitive graphical user interface, an operator types in coordinates of specified positions, and the software responds by commanding the robot to move the target to the positions. The software has capabilities for correcting errors and for recording data from the guidance-sensor system being calibrated. The software can also command that the target be moved in a predetermined sequence of motions between specified positions and can be run in an advanced control mode in which, among other things, the target can be moved beyond the limits set by the limit switches.

Workshop on Friction: Understanding and Addressing Students' Difficulties in Learning Science Through a Hermeneutical Perspective

NASA Astrophysics Data System (ADS)

Ha, Sangwoo; Lee, Gyoungho; Kalman, Calvin S.

2013-06-01

Hermeneutics is useful in science and science education by emphasizing the process of understanding. The purpose of this study was to construct a workshop based upon hermeneutical principles and to interpret students' learning in the workshop through a hermeneutical perspective. When considering the history of Newtonian mechanics, it could be considered that there are two methods of approaching Newtonian mechanics. One method is called the `prediction approach', and the other is called the `explanation approach'. The `prediction approach' refers to the application of the principles of Newtonian mechanics. We commonly use the prediction approach because its logical process is natural to us. However, its use is correct only when a force, such as gravitation, is exactly known. On the other hand, the `explanation approach' could be used when the nature of a force is not exactly known. In the workshop, students read a short text offering contradicting ideas about whether to analyze a friction situation using the explanation approach or the prediction approach. Twenty-two college students taking an upper-level mechanics course wrote their ideas about the text. The participants then discussed their ideas within six groups, each composed of three or four students. Through the group discussion, students were able to clarify their preconceptions about friction, and they responded to the group discussion positively. Students started to think about their learning from a holistic perspective. As students thought and discussed the friction problems in the manner of hermeneutical circles, they moved toward a better understanding of friction.

[Rationalities of knowledge production: on transformations of objects, technologies and information in biomedicine and the life sciences].

PubMed

Paul, Norbert W

2009-09-01

Since decades, scientific change has been interpreted in the light of paradigm shifts and scientific revolutions. The Kuhnian interpretation of scientific change however is now more and more confronted with non-disciplinary thinking in both, science and studies on science. This paper explores how research in biomedicine and the life sciences can be characterized by different rationalities, sometimes converging, sometimes contradictory, all present at the same time with varying ways of influence, impact, and visibility. In general, the rationality of objects is generated by fitting new objects and findings into a new experimental context. The rationality of hypotheses is a move towards the construction of novel explanatory tools and models. This is often inseparable meshing with the third, the technological rationality, in which a technology-driven, self-supporting and sometimes self-referential refinement of methods and technologies comes along with an extension into other fields. During the second and the third phase, the new and emerging fields tend to expand their explanatory reach not only across disciplinary boundaries but also into the social sphere, creating what has been characterized as "exceptionalism" (e.g. genetic exceptionalism or neuro-exceptionalism). Finally, recent biomedicine and life-sciences reach a level in which experimental work becomes more and more data-driven because the technologically constructed experimental systems generate a plethora of findings (data) which at some point start to blur the original hypotheses. For the rationality of information the materiality of research practices becomes secondary and research objects are more and more getting out of sight. Finally, the credibility of science as a practice becomes more and more dependent on consensus about the applicability and relevance of its results. The rationality of interest (and accountability) has become more and more characteristic for a research process which is no longer primarily determined by the desire for knowledge but by the desire for relevance. This paper explores in which ways object-driven and hypotheses-driven experimental life-sciences transformed into domains of experimental research evolving in a technologically constructed, data-driven environment in which they are subjected to constant morphing due to the forces of different rationalities.

Have I Been a Data Scientist from the Start? Parallels from the Geographic Information Science Community in the Early 1990s

NASA Astrophysics Data System (ADS)

Wright, D. J.

2013-12-01

In the early 1990s the author came of age as the technology driving the geographic information system or GIS was beginning to successfully 'handle' geospatial data at a range of scales and formats, and a wide array of information technology products emerged from an expanding GIS industry. However, that small community struggled to reflect the diverse research efforts at play in understanding the deeper issues surrounding geospatial data, and the impediments to that effective use of that data. It was from this need that geographic information science or GIScience arose, to ensure in part that GIS did not fall into the trap of being a technology in search of applications, a one-time, one-off, non-intellectual 'bag of tricks' with no substantive theory underpinning it, and suitable only for a static period of time (e.g., Goodchild, 1992). The community has since debated the issue of "tool versus science' which has also played a role in defining GIS as an actual profession. In turn, GIS has contributed to "methodological versus substantive" questions in science, leading to understandings of how the Earth works versus how the Earth should look. In the author's experience, the multidimensional structuring and scaling data, with integrative and innovative approaches to analyzing, modeling, and developing extensive and spatial data from selected places on land and at sea, have revealed how theory and application are in no way mutually exclusive, and it may often be application that advances theory, rather than vice versa. Increasingly, both the system and science of geographic information have welcomed strong collaborations among computer scientists, information scientists, and domain scientists to solve complex scientific questions. As such, they have paralleled the emergence and acceptance of "data science." And now that we are squarely in an era of regional- to global-scale observation and simulation of the Earth, produce data that are too big, move too fast, and do not fit the structures and processing capacity of conventional database systems, and the author reflects on how the potential of the GIS/GIScience world to contribute to the training and professional advancement of data science.

Bill Robertson answers this by saying, "Well, not exactly".…

Plans, Patterns, and Move Categories Guiding a Highly Selective Search

NASA Astrophysics Data System (ADS)

Trippen, Gerhard

In this paper we present our ideas for an Arimaa-playing program (also called a bot) that uses plans and pattern matching to guide a highly selective search. We restrict move generation to moves in certain move categories to reduce the number of moves considered by the bot significantly. Arimaa is a modern board game that can be played with a standard Chess set. However, the rules of the game are not at all like those of Chess. Furthermore, Arimaa was designed to be as simple and intuitive as possible for humans, yet challenging for computers. While all established Arimaa bots use alpha-beta search with a variety of pruning techniques and other heuristics ending in an extensive positional leaf node evaluation, our new bot, Rat, starts with a positional evaluation of the current position. Based on features found in the current position - supported by pattern matching using a directed position graph - our bot Rat decides which of a given set of plans to follow. The plan then dictates what types of moves can be chosen. This is another major difference from bots that generate "all" possible moves for a particular position. Rat is only allowed to generate moves that belong to certain categories. Leaf nodes are evaluated only by a straightforward material evaluation to help avoid moves that lose material. This highly selective search looks, on average, at only 5 moves out of 5,000 to over 40,000 possible moves in a middle game position.

Blogging for Soil: Why, how and having fun!

NASA Astrophysics Data System (ADS)

Drake, Jess

2014-05-01

Scientific blogging has become a more and more popular way of science outreach and communication. There are only a handful of soil science blogs, and I think there should be more! Blogging is a great way to share cool soil science stories, engage with the wider community, and promote understanding. It allows people to stumble over thoughts and ideas, and to think about how it fits in their daily life. It also provides an informal education and reference on the internet in a time where people Google everything. It can also be fun as well as being factual. At this talk, using my own experiences and the success of other soil science blogs, I will discuss: how to start a blog, why we should consider them as a way to communicate science, and what things to consider when you start your blog.

Soil mapping and process modeling for sustainable land use management: a brief historical review

NASA Astrophysics Data System (ADS)

Brevik, Eric C.; Pereira, Paulo; Muñoz-Rojas, Miriam; Miller, Bradley A.; Cerdà, Artemi; Parras-Alcántara, Luis; Lozano-García, Beatriz

2017-04-01

Basic soil management goes back to the earliest days of agricultural practices, approximately 9,000 BCE. Through time humans developed soil management techniques of ever increasing complexity, including plows, contour tillage, terracing, and irrigation. Spatial soil patterns were being recognized as early as 3,000 BCE, but the first soil maps didn't appear until the 1700s and the first soil models finally arrived in the 1880s (Brevik et al., in press). The beginning of the 20th century saw an increase in standardization in many soil science methods and wide-spread soil mapping in many parts of the world, particularly in developed countries. However, the classification systems used, mapping scale, and national coverage varied considerably from country to country. Major advances were made in pedologic modeling starting in the 1940s, and in erosion modeling starting in the 1950s. In the 1970s and 1980s advances in computing power, remote and proximal sensing, geographic information systems (GIS), global positioning systems (GPS), and statistics and spatial statistics among other numerical techniques significantly enhanced our ability to map and model soils (Brevik et al., 2016). These types of advances positioned soil science to make meaningful contributions to sustainable land use management as we moved into the 21st century.

Waters, Thomas; Baptiste, Andrea; Short, Manon; Plante-Mallon, Lori; Nelson, Audrey

2011-03-01

Moving patients can result in injuries to patients and staff members. Lateral patient transfers from a stretcher to an OR bed pose a high risk for musculoskeletal disorders, including lower back, shoulder, and neck injuries for perioperative personnel. AORN Ergonomic Tool 1: Lateral Transfer of a Patient from a Stretcher to an OR Bed helps perioperative staff members determine best practices for safe lateral patient transfers. Safe moving of the patient is determined by the starting and ending position required and the patient's weight. Current ergonomic safety concepts and scientific evidence regarding weight limits help to determine how many caregivers are needed to safely move patients and whether mechanical assistance is needed during lateral transfers.

The Lightwave programme and roadshow: an overview and update

NASA Astrophysics Data System (ADS)

Wong, Nicholas H. L.; Posner, Matthew T.; John, Pearl V.

2015-10-01

While optics and photonics are exciting disciplines with much research, industrial, and economic potential in the 21st century, this appreciation is only shared by a limited number of science, technology, engineering, and mathematics (STEM) experts, and there is a recognized STEM skills shortage. To widen the pool of talent, it is essential to expose students to optics and photonics throughout their education and particularly starting at a young age. The Lightwave programme, consisting of an interactive collection of photonics demonstrations and experiments targeted for primary school students, was thus created to facilitate this endeavor. The programme is run by doctoral students forming a team of "Lightwave ambassadors". All the demonstrations that comprise Lightwave can be easily integrated into a physics curriculum, enabling educators to generate more student interest and enhance the image of science through an interactive pedagogy. We provide a description of the programme at its initial inception, and report on the recent additions and updates that have brought about its success, moving from a purely outreach driven focus to engaging pupils with our own research. We also discuss our approach to ensuring that our team of ambassadors are from diverse backgrounds and use both male and female students as role models. Finally, we reflect on how evaluation methods to obtain feedback from our activities are key to Lightwave's sustainability and in improving the perception of optics and photonics.

Disentangling the Impact of Social Groups on Response Times and Movement Dynamics in Evacuations

PubMed Central

Bode, Nikolai W. F.; Holl, Stefan; Mehner, Wolfgang; Seyfried, Armin

2015-01-01

Crowd evacuations are paradigmatic examples for collective behaviour, as interactions between individuals lead to the overall movement dynamics. Approaches assuming that all individuals interact in the same way have significantly improved our understanding of pedestrian crowd evacuations. However, this scenario is unlikely, as many pedestrians move in social groups that are based on friendship or kinship. We test how the presence of social groups affects the egress time of individuals and crowds in a representative crowd evacuation experiment. Our results suggest that the presence of social groups increases egress times and that this is largely due to differences at two stages of evacuations. First, individuals in social groups take longer to show a movement response at the start of evacuations, and, second, they take longer to move into the vicinity of the exits once they have started to move towards them. Surprisingly, there are no discernible time differences between the movement of independent individuals and individuals in groups directly in front of the exits. We explain these results and discuss their implications. Our findings elucidate behavioural differences between independent individuals and social groups in evacuations. Such insights are crucial for the control of crowd evacuations and for planning mass events. PMID:25785603

Moving Technology to the Center of Instruction: How One Experienced Teacher Incorporates a Web-based Environment Over Time

NASA Astrophysics Data System (ADS)

Williams, Michelle

2008-08-01

The paper reports on a 3-year study of an experienced fifth grade teacher learning to integrate a Web-based Inquiry Science Environment (WISE) into his core science instruction. Data from this study included videotapes and transcripts of classroom instruction, and audiotapes and transcripts of professional development meetings and interviews conducted with the teacher as he was implementing the curriculum. The results suggest that the teacher's classroom practices shifted meaningfully over time, thus moving WISE from the peripheral to the center of his science class instruction. There was an increased integrated use of the technology by this teacher during the WISE enactments in years two and three. The teacher also engaged his students in significantly more science dialogues during the WISE online investigations. Further findings suggest that this shift in pedagogy can be attributed to repeated opportunities for the instructor to teach an inquiry-based curriculum, as well as reflecting on his teaching experiences.

This talk will start with a brief recap of the development of the ``Big Science'' epitomized by high energy physics, that is, the science that flourished after WWII based on accelerators, teams, and price tags that grew ever larger. I will then explain the transformation that started in the 1980s and culminated in the 1990s when the Cold War ended and the next big machine needed to advance high energy physics, the multi-billion dollar Superconducting Supercollider (SSC), was cancelled. I will go on to outline the curious series of events that ushered in the New Big Science, a form of research well suited to a post-Cold War environment that valued practical rather than esoteric projects. To show the impact of the New Big Science I will describe how decisions were ``set into concrete'' during the development of experimental equipment at the Thomas Jefferson National Accelerator Facility in Newport News, Virginia.

Steam stripping of the unsaturated zone of contaminated sub-soils: The effect of diffusion/dispersion in the start-up phase

NASA Astrophysics Data System (ADS)

Brouwers, H. J. H.; Gilding, B. H.

2006-02-01

The unsteady process of steam stripping of the unsaturated zone of soils contaminated with volatile organic compounds (VOCs) is addressed. A model is presented. It accounts for the effects of water and contaminants remaining in vapour phase, as well as diffusion and dispersion of contaminants in this phase. The model has two components. The first is a one-dimensional description of the propagation of a steam front in the start-up phase. This is based on Darcy's law and conservation laws of mass and energy. The second component describes the transport of volatile contaminants. Taking the view that non-equilibrium between liquid and vapour phases exists, it accounts for evaporation, transport, and condensation at the front. This leads to a moving-boundary problem. The moving-boundary problem is brought into a fixed domain by a suitable transformation of the governing partial differential equations, and solved numerically. For a broad range of the governing dimensionless numbers, such as the Henry, Merkel and Péclet numbers, computational results are discussed. A mathematical asymptotic analysis supports this discussion. The range of parameter values for which the model is valid is investigated. Diffusion and dispersion are shown to be of qualitative importance, but to have little quantitative effect in the start-up phase.

Whichever way the wind blows, scientists and engineers try to find ways to protect people and property

NASA Astrophysics Data System (ADS)

Showstack, Randy

Timothy Marshall, a failure and damage consultant with the Haag Engineering Company in Dallas, Texas, possesses a passion for storm chasing. On the afternoon of May 3, 1999, with atmospheric conditions creating a potentially explosive situation, Marshall drove several hours north to central Oklahoma to spot tornadoes. A storm started blowing up near Lawton and moved parallel to Interstate 44, with Marshall ahead of it in his Chevy pickup. He parked on the Newcastle overpass bridge, videotaping the long-tracked twister for later study At 7:04 p.m. local time, with the vortex now just one mile away and moving straight toward him, it started appearing three-dimensional, debris and projectiles flying about, the tornado roaring like freight trains, wind howling, red mud raining down, and things “getting a little out of hand,” Marshall recalled. He drove out of its path, only to watch the tornado tear through the suburban streets and houses of Moore, on its way to Oklahoma City.

Like others, Thailand education strongly focused on STEM education. This paper aimed to examine existing Thai high school students' integrated knowledge about science, technology, engineering, and mathematics (STEM) in their developing science project. The participants included 49 high school students were studying the subject of individual study (IS) in Khon Kaen wittayayon school, Khon Kaen, Thailand. The IS was provided to gradually enhance students to know how to do science project starting from getting start to do science projects, They enrolled to study the individual study of science project for three year in roll. Methodology was qualitative research. Views of students' integrated knowledge about STEM were interpreted through participant observation, interview, and students' science projects. The first author as participant observation has taught this group of students for 3 years. It found that 16 science projects were developed. Views of students' integrated knowledge about STEM could be categorized into three categories. These included (1) completely indicated integration of knowledge about science, technology, engineering, and mathematics, (2) partial indicated integration of knowledge about science, technology, engineering, and mathematics, and (3) no integration. The findings revealed that majority of science projects could be categorized as completely indicated integration of knowledge about science, technology, engineering, and mathematics. The paper suggested some ideas of enhancing students to applying STEM for developing science projects.

Harolds, Jay A

2015-06-01

After signing a contract, the new doctor has much to do before starting work, such as licensing, credentialing, finding a new home, and moving. There are important tips for a new physician in doing well in a job, such as asking for frequent feedback, doing at least one's share of the work, being at the job and available when expected, being sensitive and helpful to the needs of patients and members of the health care team, cultivating relationships, and in some cases, marketing.

Moving toward evidence-based federal Healthy Start program evaluations: accounting for bias in birth outcomes studies.

PubMed

Meghea, Cristian I; Raffo, Jennifer E; VanderMeulen, Peggy; Roman, Lee Anne

2014-02-01

We used administrative and screening data from 2009 to 2010 to determine if Healthy Start (HS), an enhanced prenatal services program, is reaching the most vulnerable African American women in Kent County, Michigan. Women in HS are at higher risk of key predictors of birth outcomes compared with other women. To advance toward evidence-based HS program evaluations in the absence of randomized controlled trials, future studies using comparison groups need to appropriately establish baseline equivalence on a variety of risk factors related to birth outcomes.

Discovery, utilisation and analysis of credible threats for 2×2 incomplete information games in the Theory of Moves framework

NASA Astrophysics Data System (ADS)

Olsen, Jolie; Sen, Sandip

2014-04-01

Steven Brams's [(1994). Theory of moves. Cambridge University Press] Theory of Moves (TOM) is an alternative to traditional game theoretic treatment of real-life interactions, in which players choose strategies based on analysis of future moves and counter-moves that arise if game play commences at a specified start state and either player can choose to move first. In repeated play, players using TOM rationality arrive at nonmyopic equilibria. One advantage of TOM is its ability to model scenarios in which power asymmetries exist between players. In particular, threat power, i.e. the ability of one player to threaten and sustain immediate, globally disadvantageous outcomes to force a desirable result long term, can be utilised to induce Pareto optimal states in games such as Prisoner's Dilemma which result in Pareto-dominated outcomes using traditional methods. Unfortunately, prior work on TOM is limited by an assumption of complete information. This paper presents a mechanism that can be used by a player to utilise threat power when playing a strict, ordinal 2×2 game under incomplete information. We also analyse the benefits of threat power and support in this analysis with empirical evidence.

The effect of butterfly-scale inspired patterning on leading-edge vortex growth

NASA Astrophysics Data System (ADS)

Wilroy, Jacob; Lang, Amy

2015-11-01

Leading edge vortices (LEVs) are important for generating thrust and lift in flapping flight, and the surface patterning (scales) on butterfly wings is hypothesized to play a role in the vortex formation of the LEV. To simplify this complex flow problem, an experiment was designed to focus on the alteration of 2-D vortex development with a variation in surface patterning. Specifically, the secondary vorticity generated by the LEV interacting at the patterned surface was studied and the subsequent affect on the growth rate of the circulation in the LEV. For this experiment we used butterfly inspired grooves attached to a flat plate and compared the vortex formation to a smooth plate case as the plate moved vertically. The plate is impulsively started in quiescent water and flow fields at Re = 1500, 3000, and 6000 are examined using Digital Particle Image Velocimetry (DPIV). The vortex formation time is 3.0 and is based on the flat plate travel length and chord length. We would like to thank the National Science Foundation REU Site Award 1358991 for funding this research.

Understanding interdependencies within Food-Energy-Water (FEW) systems is critical to maintain FEW security. This project examines how coordinated management of physical (e.g., reservoirs, aquifers, and batteries) and non-physical (e.g., water markets, social capital, and insurance markets) storage systems across the three sectors promotes resilience. Coordination increases effective storage within the overall system and enhances buffering against shocks at multiple scales. System-wide resilience can be increased with innovations in technology (e.g., smart systems and energy storage) and institutions (e.g., economic systems and water law). Using the Columbia River Basin as our geographical study region, we use an integrated approach that includes a continuum of science disciplines, moving from theory to practice. In order to understand FEW linkages, we started with detailed, connected conceptual models of the food, energy, water, and social systems to identify where key interdependencies (i.e., overlaps, stocks, and flows) exist within and between systems. These are used to identify stress and opportunity points, develop innovation solutions across FEW sectors, remove barriers to the adoption of solutions, and quantify increases in system-wide resilience to regional and global change. The conceptual models act as a foundation from which we can identify key drivers, parameters, time steps, and variables of importance to build and improve existing systems dynamic and biophysical models. Our process of developing conceptual models and moving to integrated modeling is critical and serves as a foundation for coupling quantitative components with economic and social domain components and analyses of how these interact through time and space. This poster provides a description of this process that pulls together conceptual maps and integrated modeling output to quantify resilience across all three of the FEW sectors (a.k.a. "The Resilience Calculator"). Companion posters describe our case studies and our efforts in incorporating social systems into this resilience calculator.

Adverse Consequences of School Mobility for Children in Foster Care: A Prospective Longitudinal Study

PubMed Central

Pears, Katherine C.; Kim, Hyoun K.; Buchanan, Rohanna; Fisher, Philip A.

2015-01-01

Few prospective studies have examined school mobility in children in foster care. This study described the school moves of 86 such children and 55 community comparison children (primarily Caucasian), living in a medium-sized metropolitan area in the Pacific Northwest who were approximately 3-6-years-old at the study start. Additionally, the effects of moves from kindergarten through Grade 2 on academic and social emotional competence in Grades 3 through 5 were examined. A greater number of early school moves was associated with poorer later social emotional competence and partially mediated the effects of maltreatment and out-of-home placement on social emotional competence. This was only the case for children with poorer early learning skills in kindergarten. Implications for preventive intervention are discussed. PMID:25906815

Making sense of the complex entanglement between emotion and pedagogy: contributions of the affective turn

NASA Astrophysics Data System (ADS)

Zembylas, Michalinos

2016-09-01

The purpose of this paper is to highlight three recent contributions of the affective turn: moving beyond the emotion/reason dichotomy; highlighting the politics of emotion and affect; and, strengthening the intersections of the psychic and the social. While these contributions are not necessarily paradigmatic of scholarship in the affective turn, they do highlight some important threads of thinking about affect theory in several fields of study, and thus they can be insightful in the context of science education as well. This discussion is motivated by the notion that science teaching and learning can benefit theoretically from these latest developments of affect theory. Although the question of why science teaching and learning has not paid so much attention to emotion and affect in the past is no less important, this paper will move past this in an effort to focus on the openings that are created for pedagogy in general.

Dawn Usage, Scheduling, and Governance Model

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

Louis, S

2009-11-02

This document describes Dawn use, scheduling, and governance concerns. Users started running full-machine science runs in early April 2009 during the initial open shakedown period. Scheduling Dawn while in the Open Computing Facility (OCF) was controlled and coordinated via phone calls, emails, and a small number of controlled banks. With Dawn moving to the Secure Computing Facility (SCF) in fall of 2009, a more detailed scheduling and governance model is required. The three major objectives are: (1) Ensure Dawn resources are allocated on a program priority-driven basis; (2) Utilize Dawn resources on the job mixes for which they were intended;more » and (3) Minimize idle cycles through use of partitions, banks and proper job mix. The SCF workload for Dawn will be inherently different than Purple or BG/L, and therefore needs a different approach. Dawn's primary function is to permit adequate access for tri-lab code development in preparation for Sequoia, and in particular for weapons multi-physics codes in support of UQ. A second purpose is to provide time allocations for large-scale science runs and for UQ suite calculations to advance SSP program priorities. This proposed governance model will be the basis for initial time allocation of Dawn computing resources for the science and UQ workloads that merit priority on this class of resource, either because they cannot be reasonably attempted on any other resources due to size of problem, or because of the unavailability of sizable allocations on other ASC capability or capacity platforms. This proposed model intends to make the most effective use of Dawn as possible, but without being overly constrained by more formal proposal processes such as those now used for Purple CCCs.« less

The Large Synoptic Survey Telescope will usher in a new age of astronomical data exploration for science educators and students. LSST data sets will be large, deep, and dynamic, and will establish a time-domain record that will extend over a decade. They will be used to provide engaging, relevant learning experiences.The EPO Team will develop online investigations using authentic LSST data that offer varying levels of challenge and depth by the start of telescope operations, slated to begin in 2022. The topics will cover common introductory astronomy concepts, and will align with the four science domains of LSST: The Milky Way, the changing sky (transients), solar system (moving) objects, and dark matter and dark energy.Online Jupyter notebooks will make LSST data easily available to access and analyze by students at the advanced middle school through college levels. Using online notebooks will circumvent common obstacles caused by firewalls, bandwidth issues, and the need to download software, as they will be accessible from any computer or tablet with internet access. Although the LSST EPO Jupyter notebooks are Python-based, a knowledge of programming will not be required to use them.Each topical investigation will include teacher and student versions of Jupyter notebooks, instructional videos, and access to a suite of support materials including a forum, and professional development training and tutorial videos.Jupyter notebooks will contain embedded widgets to process data, eliminating the need to use external spreadsheets and plotting software. Students will be able to analyze data by using some of the existing modules already developed for professional astronomers. This will shorten the time needed to conduct investigations and will shift the emphasis to understanding the underlying science themes, which is often lost with novice learners.

Incorporating Social System Dynamics into the Food-Energy-Water System Resilience-Sustainability Modeling Process

NASA Astrophysics Data System (ADS)

Givens, J.; Padowski, J.; Malek, K.; Guzman, C.; Boll, J.; Adam, J. C.; Witinok-Huber, R.

2017-12-01

In the face of climate change and multi-scalar governance objectives, achieving resilience of food-energy-water (FEW) systems requires interdisciplinary approaches. Through coordinated modeling and management efforts, we study "Innovations in the Food-Energy-Water Nexus (INFEWS)" through a case-study in the Columbia River Basin. Previous research on FEW system management and resilience includes some attention to social dynamics (e.g., economic, governance); however, more research is needed to better address social science perspectives. Decisions ultimately taken in this river basin would occur among stakeholders encompassing various institutional power structures including multiple U.S. states, tribal lands, and sovereign nations. The social science lens draws attention to the incompatibility between the engineering definition of resilience (i.e., return to equilibrium or a singular stable state) and the ecological and social system realities, more explicit in the ecological interpretation of resilience (i.e., the ability of a system to move into a different, possibly more resilient state). Social science perspectives include but are not limited to differing views on resilience as normative, system persistence versus transformation, and system boundary issues. To expand understanding of resilience and objectives for complex and dynamic systems, concepts related to inequality, heterogeneity, power, agency, trust, values, culture, history, conflict, and system feedbacks must be more tightly integrated into FEW research. We identify gaps in knowledge and data, and the value and complexity of incorporating social components and processes into systems models. We posit that socio-biophysical system resilience modeling would address important complex, dynamic social relationships, including non-linear dynamics of social interactions, to offer an improved understanding of sustainable management in FEW systems. Conceptual modeling that is presented in our study, represents a starting point for a continued research agenda that incorporates social dynamics into FEW system resilience and management.

Drilling reorganizes

NASA Astrophysics Data System (ADS)

Richman, Barbara T.

As the first in a proposed series of steps that would move scientific ocean drilling from its own niche within the National Science Foundation's (NSF) Directorate for Astronomical, Atmospheric, Earth, and Ocean Sciences (AAEO) into the agency's Division of Ocean Sciences, Grant Gross, division director, has been appointed acting director of the Office of Scientific Ocean Drilling (OSOD). Gross will retain the directorship of the division, which also is part of AAEO. Allen M. Shinn, Jr., OSOD director for nearly 2 years, has been reassigned effective July 10 to a position in NSF's Office of Planning and Resource Management.The move aims to tie drilling operations more closely to the science with which it is associated, Gross said. This first step is an organizational response to the current leaning toward using a commercial drilling vessel as the drilling platform, he said. Before the market for such commercial drill ships opened (Eos, February 22, 1983, p . 73), other ship options for scientific ocean drilling included refurbishing the aging Glomar Challenger or renovating, at great expense, the Glomar Explorer. A possible next step in the reorganization is to make OSOD the third section within the Ocean Sciences Division. Currently, the division is divided into the Oceanographic Facilities and Support Section and the Ocean Sciences Research Section.

Anticipatory Governance: Bioethical Expertise for Human/Animal Chimeras

PubMed Central

Harvey, Alison; Salter, Brian

2012-01-01

The governance demands generated by the use of human/animal chimeras in scientific research offer both a challenge and an opportunity for the development of new forms of anticipatory governance through the novel application of bioethical expertise. Anticipatory governance can be seen to have three stages of development whereby bioethical experts move from a reactive to a proactive stance at the edge of what is scientifically possible. In the process, the ethicists move upstream in their engagement with the science of human-to-animal chimeras. To what extent is the anticipatory coestablishment of the principles and operational rules of governance at this early stage in the development of the human-to-animal research field likely to result in a framework for bioethical decision making that is in support of science? The process of anticipatory governance is characterised by the entwining of the scientific and the philosophical so that judgements against science are also found to be philosophically unfounded, and conversely, those activities that are permissible are deemed so on both scientific and ethical grounds. Through what is presented as an organic process, the emerging bioethical framework for human-to-animal chimera research becomes a legitimating framework within which ‘good’ science can safely progress. Science gives bioethical expertise access to new governance territory; bioethical expertise gives science access to political acceptability. PMID:23576848

A refined technique to calculate finite helical axes from rigid body trackers.

PubMed

McLachlin, Stewart D; Ferreira, Louis M; Dunning, Cynthia E

2014-12-01

Finite helical axes (FHAs) are a potentially effective tool for joint kinematic analysis. Unfortunately, no straightforward guidelines exist for calculating accurate FHAs using prepackaged six degree-of-freedom (6 DOF) rigid body trackers. Thus, this study aimed to: (1) describe a protocol for calculating FHA parameters from 6 DOF rigid body trackers using the screw matrix and (2) to maximize the number of accurate FHAs generated from a given data set using a moving window analysis. Four Optotrak® Smart Markers were used as the rigid body trackers, two moving and two fixed, at different distances from the hinge joint of a custom-machined jig. 6D OF pose information was generated from 51 static positions of the jig rotated and fixed in 0.5 deg increments up to 25 deg. Output metrics included the FHA direction cosines, the rotation about the FHA, the translation along the axis, and the intercept of the FHA with the plane normal to the jig's hinge joint. FHA metrics were calculated using the relative tracker rotation from the starting position, and using a moving window analysis to define a minimum acceptable rotational displacement between the moving tracker data points. Data analysis found all FHA rotations calculated from the starting position were within 0.15 deg of the prescribed jig rotation. FHA intercepts were most stable when determined using trackers closest to the hinge axis. Increasing the moving window size improved the FHA direction cosines and center of rotation accuracy. Window sizes larger than 2 deg had an intercept deviation of less than 1 mm. Furthermore, compared to the 0 deg window size, the 2 deg window had a 90% improvement in FHA intercept precision while generating almost an equivalent number of FHA axes. This work identified a solution to improve FHA calculations for biomechanical researchers looking to describe changes in 3D joint motion.

Moving Liquids with Sound: The Physics of Acoustic Droplet Ejection for Robust Laboratory Automation in Life Sciences.

PubMed

Hadimioglu, Babur; Stearns, Richard; Ellson, Richard

2016-02-01

Liquid handling instruments for life science applications based on droplet formation with focused acoustic energy or acoustic droplet ejection (ADE) were introduced commercially more than a decade ago. While the idea of "moving liquids with sound" was known in the 20th century, the development of precise methods for acoustic dispensing to aliquot life science materials in the laboratory began in earnest in the 21st century with the adaptation of the controlled "drop on demand" acoustic transfer of droplets from high-density microplates for high-throughput screening (HTS) applications. Robust ADE implementations for life science applications achieve excellent accuracy and precision by using acoustics first to sense the liquid characteristics relevant for its transfer, and then to actuate transfer of the liquid with customized application of sound energy to the given well and well fluid in the microplate. This article provides an overview of the physics behind ADE and its central role in both acoustical and rheological aspects of robust implementation of ADE in the life science laboratory and its broad range of ejectable materials. © 2015 Society for Laboratory Automation and Screening.

Health sciences libraries building survey, 1999-2009.

Ludwig, Logan

2010-04-01

A survey was conducted of health sciences libraries to obtain information about newer buildings, additions, remodeling, and renovations. An online survey was developed, and announcements of survey availability posted to three major email discussion lists: Medical Library Association (MLA), Association of Academic Health Sciences Libraries (AAHSL), and MEDLIB-L. Previous discussions of library building projects on email discussion lists, a literature review, personal communications, and the author's consulting experiences identified additional projects. Seventy-eight health sciences library building projects at seventy-three institutions are reported. Twenty-two are newer facilities built within the last ten years; two are space expansions; forty-five are renovation projects; and nine are combinations of new and renovated space. Six institutions report multiple or ongoing renovation projects during the last ten years. The survey results confirm a continuing migration from print-based to digitally based collections and reveal trends in library space design. Some health sciences libraries report loss of space as they move toward creating space for "community" building. Libraries are becoming more proactive in using or retooling space for concentration, collaboration, contemplation, communication, and socialization. All are moving toward a clearer operational vision of the library as the institution's information nexus and not merely as a physical location with print collections.

Land Recycling: from Science to Practice - A Sustainable Development of Urban Areas

2015-12-01

Member States (MS) of the European Union have experience significant urban sprawl in the last 3 decades. The urban sprawl was driven mainly by internal (MS or EU) or external migration but also by EU policies (including funds and projects) and by changes in life style (e.g. moving away from cities; second homes). This presentation will aim at showing a number of EU wide analysis on: aging population, depopulation of some of the EU regions; agricultural production and scenarios projections of thereof. Various EU funded projects and programs have analyzed ways how future cities and how EU future land use could developed. Number of those solutions where further investigated with case studies/small scale implementations. However, in recent years the 2012 EU road map to resource efficiency and UN Sustainable Development Goals have called respectively for 'no net land take by 2050' and land neutrality. Thus, the process of implementing innovative solutions for land use has started and some of the cities and regions are well ahead in moving towards XXI century society. In order to streamline/share knowledge and steer EU wide discussion on this the European Commission in its road map to resource efficiency announced a Communication on land as a resource. This presentation will attempt to synthesize current discussion on the topic of 'land as a resource' and include examples of implemented innovative solutions for aging population, land recycling for urban developments and green spaces within the current EU policy context. Finally, some appreciation of the adopted UN Sustainable Development Goals regarding land and soil from the EU perspective will be given.

A long-standing goal of artificial intelligence is an algorithm that learns, tabula rasa, superhuman proficiency in challenging domains. Recently, AlphaGo became the first program to defeat a world champion in the game of Go. The tree search in AlphaGo evaluated positions and selected moves using deep neural networks. These neural networks were trained by supervised learning from human expert moves, and by reinforcement learning from self-play. Here we introduce an algorithm based solely on reinforcement learning, without human data, guidance or domain knowledge beyond game rules. AlphaGo becomes its own teacher: a neural network is trained to predict AlphaGo's own move selections and also the winner of AlphaGo's games. This neural network improves the strength of the tree search, resulting in higher quality move selection and stronger self-play in the next iteration. Starting tabula rasa, our new program AlphaGo Zero achieved superhuman performance, winning 100-0 against the previously published, champion-defeating AlphaGo.

A more accurate method using MOVES (Motor Vehicle Emission Simulator) to estimate emission burden for regional-level analysis.

PubMed

Liu, Xiaobo

2015-07-01

The U.S. Environmental Protection Agency's (EPA) Motor Vehicle Emission Simulator (MOVES) is required by the EPA to replace Mobile 6 as an official on-road emission model. Incorporated with annual vehicle mile traveled (VMT) by Highways Performance Monitoring System (HPMS) vehicle class, MOVES allocates VMT from HPMS to MOVES source (vehicle) types and calculates emission burden by MOVES source type. However, the calculated running emission burden by MOVES source type may be deviated from the actual emission burden because of MOVES source population, specifically the population fraction by MOVES source type in HPMS vehicle class. The deviation is also the result of the use of the universal set of parameters, i.e., relative mileage accumulation rate (relativeMAR), packaged in MOVES default database. This paper presents a novel approach by adjusting the relativeMAR to eliminate the impact of MOVES source population on running exhaust emission and to keep start and evaporative emissions unchanged for both MOVES2010b and MOVES2014. Results from MOVES runs using this approach indicated significant improvements on VMT distribution and emission burden estimation for each MOVES source type. The deviation of VMT by MOVES source type is minimized by using this approach from 12% to less than 0.05% for MOVES2010b and from 50% to less than 0.2% for MOVES2014 except for MOVES source type 53. Source type 53 still remains about 30% variation. The improvement of VMT distribution results in the elimination of emission burden deviation for each MOVES source type. For MOVES2010b, the deviation of emission burdens decreases from -12% for particulate matter less than 2.5 μm (PM2.5) and -9% for carbon monoxide (CO) to less than 0.002%. For MOVES2014, it drops from 80% for CO and 97% for PM2.5 to 0.006%. This approach is developed to more accurately estimate the total emission burdens using EPA's MOVES, both MOVES2010b and MOVES2014, by redistributing vehicle mile traveled (VMT) by Highways Performance Monitoring System (HPMS) class to MOVES source type on the basis of comprehensive traffic study, local link-by-link VMT broken down into MOVES source type.

Scientists Have Feelings, Too. We Can Connect Emotions and Intellect to Reach Big Audiences, and Then Move Them.

NASA Astrophysics Data System (ADS)

Tenenbaum, L. F.

2016-12-01

Most of us in the science community have been rewarded for our brainpower throughout our lives. Therefore we've learned to rely heavily on our intellectual skills, even though we're clearly much more than disembodied brainiacs. What would happen if we tried to combine our emotions and intellect to communicate with the public? Would it foster deeper connections? NASA's Earth Right Now blog author Laura Faye Tenenbaum noticed that science communication sometimes flat-lines at "Wow," as if that's the only acceptable emotion we can feel. And even though emotions such as anger, frustration disappointment, or joy are messy and uncomfortable, and even though we sometimes worry that showing too much playfulness might prevent our scientific messages from being taken seriously, we decided that writing personal and emotional science stories would be worth a try. In January 2014, Tenenbaum brought her teaching and public speaking experience and her entertainment industry communication knowledge to the Earth Right Now blog. It quickly became one of NASA's most popular, most heavily commented and most shared blogs. We found that, when we combined "feeling" and "thinking," communication thrived and we were able to reach a much wider audience. We learned that to move people, we could begin by tapping into what we were moved by. We saw how lifting the mask of the starchy, nerdy stereotype to show that scientists are real people who experience deep emotions on the job is a best practice for enhancing the public perception of science. As a case study on the effect of using emotional content in communication, the Earth Right Now blog showed not only that it's possible, it's actually beneficial to include complex and authentic emotion in solid science communication.

GET21: Geoinformatics Training and Education for the 21st Century Geoscience Workforce

Baru, C.; Allison, L.; Fox, P.; Keane, C.; Keller, R.; Richard, S.

2012-04-01

The integration of advanced information technologies (referred to as cyberinfrastructure) into scientific research and education creates a synergistic situation. On the one hand, science begins to move at the speed of information technology, with science applications having to move rapidly to keep apace with the latest innovations in hardware and software. On the other hand, information technology moves at the pace of science, requiring rapid prototyping and rapid development of software and systems to serve the immediate needs of the application. The 21st century geoscience workforce must be adept at both sides of this equation to be able to make the best use of the available cyber-tools for their science and education endeavors. To reach different segments of the broad geosciences community, an education program in geoinformatics must be multi-faceted, ranging from areas dealing with modeling, computational science, and high performance computing, to those dealing with data collection, data science, and data-intensive computing. Based on our experience in geoinformatics and data science education, we propose a multi-pronged approach with a number of different components, including summer institutes typically aimed at graduate students, postdocs and researchers; graduate and undergraduate curriculum development in geoinformatics; development of online course materials to facilitate asynchronous learning, especially for geoscience professionals in the field; provision of internship at geoinformatics-related facilities for graduate students, so that they can observe and participate in geoinformatics "in action"; creation of online communities and networks to facilitate planned as well as serendipitous collaborations and for linking users with experts in the different areas of geoscience and geoinformatics. We will describe some of our experiences and the lessons learned over the years from the Cyberinfrastructure Summer Institute for Geoscientists (CSIG), which is a 1-week institute that has been held each summer (August) at the San Diego Supercomputer Center, University of California, San Diego, since 2005. We will also discuss these opportunities for GET21 and geoinformatics education in the context of the newly launched EarthCube initiative at the US National Science Foundation.

BOOK REVIEW: The Odd Quantum

NASA Astrophysics Data System (ADS)

Reynolds, Helen

2000-03-01

The Odd Quantum is aiming to be odd. Falling between being a quantum mechanics textbook and a `popular' science book, it aims to convey something of the substance of quantum mechanics without being overly technical or professional. It does not shy away from the mathematics of the subject or resort solely to analogy and metaphor, as so often is the case. Books aimed at the lay reader tend to take on a particular aspect of quantum mechanics, for example, wave-particle duality, and can do little more than hint at the complexity of the subject. This book is more than a textbook on quantum mechanics; it gives the reader a comprehensive account of history and an appreciation of the nature of quantum mechanics. The introductory chapters deal with the earlier part of the century and the thinking of that time. The approach is familiar, as are the stories that Treiman tells, but he also manages to convey the speed with which ideas changed and the excitement this brought to the physics community. Classical ideas of force and energy are dealt with succinctly but with sufficient depth to set up the reader for what is to come; Maxwell's equations and a brief glimpse at relativity are included. This is followed by a brief description of what the author terms the `old' quantum mechanics, in effect a highly readable tour around black body radiation and spectroscopy and the models of the atom that emerged from them. The `new' quantum mechanics begins about a third of the way through the book, and in a chapter entitled `Foundations' starts gently but rapidly moves into a detailed mathematical treatment. This section, of necessity, relapses into the style of a textbook and covers a lot of ground quickly. It is at this point that the non-specialist popular science readers for whom Treiman has written this book may become a little bemused. Concepts such as non-degeneracy and operators come thick and fast. It is difficult to imagine an educated non-physicist with little mathematical ability keeping track of the equations and their meaning. However, the text continues to be accessible and moves swiftly from `quantum classics' such as the harmonic oscillator to electrical conductivity and the collapse of stars. Reassuringly, Treiman takes time out to ask `What's going on?' where he considers the question of how probabilities get converted into `facts' when things are measured. His own fascination with the subject comes through as he considers the different interpretations of quantum mechanics. The chapter on `building blocks' starts in 1932 when ` ... it could seem that all the basic building blocks of the whole world were at last in hand'. Swiftly and succinctly it moves through to the standard model, acknowledging that a closer look would ` ... quickly carry us far afield into highly technical thickets'. The final chapter tackles the more difficult subject of quantum field theory. This is a very swift journey through quantum electrodynamics and quantum chromodynamics. It is the final summary that stands out, however. The author reminds us what to marvel about: the miracles of quantum theory that are ` ... outrageous to common sense and intuition'. This is a useful book for any science department. It will be of particular use to those of us who studied the subject some time ago and who need to refresh their memories, for example teachers of A-level physics. The asides about `what is going on' and the history that is included make it a `book' rather than a `textbook'. First-year undergraduates, or just possibly motivated and mathematically able A-level students, would also benefit. Beware, however. The mathematics is not trivial and you would arguably need to have met it before in order to cope. Although the book occasionally relapses into textbook style you are left with a sense of the wonder of the subject and an appreciation of the beauty of the mathematics that underpins it.

Five-hundred-meter Aperture Spherical radio Telescope (FAST) is a Chinese mega-science project to build the largest single dish radio telescope in the world. Its innovative engineering concept and design pave a new road to realize a huge single dish in the most effective way. FAST also represents Chinese contribution in the international efforts to build the square kilometer array (SKA). Being the most sensitive single dish radio telescope, FAST will enable astronomers to jump-start many science goals, such as surveying the neutral hydrogen in the Milky Way and other galaxies, detecting faint pulsars, looking for the first shining stars, hearing the possible signals from other civilizations, etc. The idea of sitting a large spherical dish in a karst depression is rooted in Arecibo telescope. FAST is an Arecibo-type antenna with three outstanding aspects: the karst depression used as the site, which is large to host the 500-meter telescope and deep to allow a zenith angle of 40 degrees; the active main reflector correcting for spherical aberration on the ground to achieve a full polarization and a wide band without involving complex feed systems; and the light-weight feed cabin driven by cables and servomechanism plus a parallel robot as a secondary adjustable system to move with high precision. The feasibility studies for FAST have been carried out for 14 years, supported by Chinese and world astronomical communities. Funding for FAST has been approved by the National Development and Reform Commission in July of 2007 with a capital budget ~ 700 million RMB. The project time is 5.5 years from the commencement of work in March of 2011 and the first light is expected to be in 2016. This review intends to introduce the project of FAST with emphasis on the recent progress since 2006. In this paper, the subsystems of FAST are described in modest details followed by discussions of the fundamental science goals and examples of early science projects.

A Study of Novice Science Teachers' Conceptualizations of Culturally Relevant Pedagogy

NASA Astrophysics Data System (ADS)

Redman, Elizabeth Horst

This qualitative study examined new science teachers' conceptualization of culturally relevant pedagogy (CRP). The study followed six novice science teachers from their preservice teaching placements into their first jobs as instructors of record, observing in their classrooms and interviewing them about their use of CRP. The study sought to understand (1) how the participating teachers conceptualize CRP in science, and (2) what challenges the teachers faced in trying to implement CRP. Findings suggest that the teachers conceptualized CRP in ways that were consistent with Enyedy, Danish and Fields' (2011) interpretations of relevance: relevance of authentic purpose, relevance of content and/or context, and relevance of practices. The teachers, however, translated those interpretations of relevance into their conceptualizations and classroom practice in a variety of ways. While they encountered difficulties in conceptualizing and practicing CRP, they also made productive moves in their practice and evidenced positive elements in their conceptualizations of CRP. In order to address the challenges these teachers faced in implementing CRP, I suggest an approach to teacher preparation in CRP that builds upon the understandings and productive moves the teachers evidenced in this study.

`You Have to Give Them Some Science Facts': Primary Student Teachers' Early Negotiations of Teacher Identities in the Intersections of Discourses About Science Teaching and About Primary Teaching

NASA Astrophysics Data System (ADS)

Danielsson, Anna T.; Warwick, Paul

2014-04-01

In the broadest sense, the goal for primary science teacher education could be described as preparing these teachers to teach for scientific literacy. Our starting point is that making such science teaching accessible and desirable for future primary science teachers is dependent not only on their science knowledge and self-confidence, but also on a whole range of interrelated sociocultural factors. This paper aims to explore how intersections between different Discourses about primary teaching and about science teaching are evidenced in primary school student teachers' talk about becoming teachers. The study is founded in a conceptualisation of learning as a process of social participation. The conceptual framework is crafted around two key concepts: Discourse (Gee 2005) and identity (Paechter, Women's Studies International Forum, 26(1):69-77, 2007). Empirically, the paper utilises semi-structured interviews with 11 primary student teachers enrolled in a 1-year Postgraduate Certificate of Education course. The analysis draws on five previously identified teacher Discourses: `Teaching science through inquiry', `Traditional science teacher', `Traditional primary teacher', `Teacher as classroom authority', and `Primary teacher as a role model' (Danielsson and Warwick, International Journal of Science Education, 2013). It explores how the student teachers, at an early stage in their course, are starting to intersect these Discourses to negotiate their emerging identities as primary science teachers.

Moving Toward Evidence-Based Federal Healthy Start Program Evaluations: Accounting for Bias in Birth Outcomes Studies

2014-01-01

We used administrative and screening data from 2009 to 2010 to determine if Healthy Start (HS), an enhanced prenatal services program, is reaching the most vulnerable African American women in Kent County, Michigan. Women in HS are at higher risk of key predictors of birth outcomes compared with other women. To advance toward evidence-based HS program evaluations in the absence of randomized controlled trials, future studies using comparison groups need to appropriately establish baseline equivalence on a variety of risk factors related to birth outcomes.

Liquid crystal templating as an approach to spatially and temporally organise soft matter.

PubMed

van der Asdonk, Pim; Kouwer, Paul H J

2017-10-02

Chemistry quickly moves from a molecular science to a systems science. This requires spatial and temporal control over the organisation of molecules and molecular assemblies. Whilst Nature almost by default (transiently) organises her components at multiple different length scales, scientists struggle to realise even relatively straightforward patterns. In the past decades, supramolecular chemistry has taught us the rules to precisely engineer molecular assembly at the nanometre scale. At higher length scales, however, we are bound to top-down nanotechnology techniques to realise order. For soft, biological matter, many of these top-down techniques come with serious limitations since the molecules generally show low susceptibilities to the applied stimuli. A new method is based on liquid crystal templating. In this hierarchical approach, a liquid crystalline host serves as the scaffold to order polymers or assemblies. Being a liquid crystal, the host material can be ordered at many different length scales and on top of that, is highly susceptible to many external stimuli, which can even be used to manipulate the liquid crystal organisation in time. As a result, we anticipate large control over the organisation of the materials inside the liquid crystalline host. Recently, liquid crystal templating was also realised in water. This suddenly makes this tool highly applicable to start organising more delicate biological materials or even small organisms. We review the scope and limitations of liquid crystal templating and look out to where the technique may lead us.

GLOBE Goes GO with Mosquitoes

NASA Astrophysics Data System (ADS)

Boger, R. A.; Low, R.

2016-12-01

The GLOBE Mosquito Larvae protocol and a new citizen science initiative, GLOBE Observers (GO), were both launched in Summer 2016. While the GLOBE Mosquito Larvae Protocol and associated educational materials target K-16 student inquiry and research, the GO protocol version is simplified to enable citizen scientists of all ages from all walks of life to participate. GO allows citizen scientists to collect and submit environmental data through an easy-to-use smart phone app available for both Apple and Android mobile devices. GO mosquito asks for photos of larvae mosquito genus or species, location, and type of water source (e.g., container or pond) where the larvae were found. To initiate the new mosquito GLOBE/GO opportunities, workshops have been held in Barbuda, Thailand, West Indies, US Gulf Coast, New York City, and at the GLOBE Annual Meeting in Colorado. Through these venues, the protocols have been refined and a field campaign has been initiated so that GO and GLOBE citizen scientists (K-16 students and all others) can contribute data. Quality assurance measures are taken through the online training required to participate and the validation of identification by other citizen sciences and mosquito experts. Furthermore, initial research is underway to develop optical recognition software starting with the species that carry the Zika virus (Aedes aegypti and A. albopictus). With this launch, we plan to move forward by providing opportunities throughout the world to engage people in meaningful environmental and public health data collection and to promote citizen scientists to become agents of change in their communities.

Retaining Underrepresented Minority Undergraduates in STEM through Hands-on Internship Experiences

2015-12-01

The U.S. Department of the Interior's South Central Climate Science Center (SCCSC) hosts an annual 3-week summer internship opportunity for undergraduate students of underrepresented minorities interested in science, technology, engineering and mathematics (STEM) fields. Internship participants travel across the south-central U.S. to visit university campuses and field locations. The students interact with faculty conducting cutting edge research and with resource managers facing decision-making under uncertainty. This internship format allows the participants to see the direct impacts of climate variability and change on the Texas Hill Country, prairie and forest ecosystems and tribal cultures in Oklahoma, and the bayous, delta and coastline of Louisiana. Immersive experiences are key for exposing students to academic research and providing them with the skills and experiences needed to continue on in their professional careers. The SCCSC's program introduces students to how research is conducted, gives them a broad perspective on how collaborations form, and starts each student on the path to building a large and diverse professional network. By providing participants with a "buffet" of options, our internship serves as a launching pad from which each student can move forward towards experiences such as participating in a Research Experiences for Undergraduates program, gaining employment in a STEM-related career path, and being accepted into a graduate degree program. This presentation will describe the components of the SCCSC's internship program and provide a summary of post-internship student successes.

Gunnar, Megan R

2017-07-01

In unpredictable times, it is perhaps even more important to contemplate the direction different fields of science are headed. In this article, I contemplate two directions of psychological science: the increasing integration of the study of psychology with other sciences and the concern of many sciences, including ours, with improving the reproducibility of our findings. Both of these are argued to be "right ways," but these directions also have challenges that, unless carefully addressed, could detract from our ability to move the science of psychology forward. I detail these challenges along with a consideration of how to chart our science through the unpredictable waters we face at this point in history.

Public understanding of chemistry research in print news

NASA Astrophysics Data System (ADS)

Hands, Michael D., Jr.

Despite numerous calls for improving scientific literacy, many American adults show a lack of understanding of experiments, scientific study, and scientific inquiry. News media is one important avenue for science learning, but previous research investigating health and/or environmental science news has shown that it is inconsistent in the presentation of scientific research limitations, potentially impacting reader understanding. In the first phase of this dissertation, seventeen news articles reporting on a single chemistry research article, along with associated press releases and research articles, were analyzed using move analysis to determine the structure of each type of text. It was found that the overall structure of each text genre was similar, with the main difference being that research articles start by presenting background information, while the others lead with highlighting overall research outcomes. Analysis of the steps revealed that, as seen for health and environmental science news articles, descriptions of the study limitations and methods were generally omitted in the news articles. Using these findings, a pilot study was conducted where study limitations were added to a chemistry research news article and the effect of its presence on staff members employed at a large Midwestern university (n=12) and science faculty employed at the same institution (n=6) was explored. Interviews with the participants revealed that including limitations enhanced readers' ability to identify conclusions and evaluate claims, but decreased their trust in the information. In the final part of this study, the trends seen in the previous phase were explored to determine their generalizability. Members of the public (n=232) and science faculty (n=191) read a randomly assigned news article either presenting or omitting the study limitations and research methods. Participants reading articles presenting limitations were able to evaluate the reasonableness of claims based on the article better than those who read the article omitting limitations when accounting for their views on the tentativeness of science (ToS). Presenting limitations was important in identifying unreasonable claims for both public and science faculty, while ToS views predicted ability to identify reasonable claims for the public. Including limitations also decreased readers' trust in the conclusions of the research. However, it did not impact their ability to determine the conclusions of the research and including methods did not have any effect on the measured outcomes.

This paper analyses the recent widespread moves to 'restore' public trust in science by developing an avowedly two-way, public dialogue with science initiatives. Noting how previously discredited and supposedly abandoned public deficit explanations of 'mistrust' have actually been continually reinvented, it argues that this is a symptom of a continuing failure of scientific and policy institutions to place their own science-policy institutional culture into the frame of dialogue, as possible contributory cause of the public mistrust problem.

Forensic chemistry is unique among chemical sciences in that its research, practice, and presentation must meet the needs of both the scientific and the legal communities. As such, forensic chemistry research is applied and derivative by nature and design, and it emphasizes metrology (the science of measurement) and validation. Forensic chemistry has moved away from its analytical roots and is incorporating a broader spectrum of chemical sciences. Existing forensic practices are being revisited as the purview of forensic chemistry extends outward from drug analysis and toxicology into such diverse areas as combustion chemistry, materials science, and pattern evidence.

Application work risk of manual material handling operators using different lifting methods

NASA Astrophysics Data System (ADS)

Anizar; Matondang, AR; Sibarani, JA

2018-02-01

This study observed the activity of lifting and moving crates containing bottles at a pallet station in a carbonated drink factory. The activity of moving crates, each weighing 15 kg, is performed by four operators using different methods. An operator manually moves 250 crates daily and often takes rest during working. This study aims to find the most efficient method, that is using the least energy, to move crates. The workload is assessed using the method of Cardiovascular Strain Load (CVL) and energy expenditure. Operators’ arterial pulse is measured for 1 minute right before they start working and after they finish working; this is done to obtain work arterial pulse and rest arterial pulse. The way operators lift crates is analyzed using biomechanics. It is found that fatigue is experienced by all operators, with the exception of the 3rd operator who has a %CVL number below 30%. He positions the pallet to be parallel to the conveyor, and then stand in between during the lifting process. He only rotates his body to move the crate from the conveyor onto the pallet, requiring only little energy. This is one of the reasons why the %CVL number is lower than the other operators.

Objective To evaluate and provide a real-life view of the operation of the Healthy Start vitamins scheme. Setting The study took place in primary care and community settings that served rural, urban and ethnically diverse populations, in two sentinel sites: London, and Yorkshire and the Humber. An online consultation and stakeholder workshops elicited views from across England. Participants 669 health and social care practitioners including health visitors, midwives, public health practitioners, general practitioners, paediatricians and support staff participated in focus group discussions (n=49) and an online consultation (n=620). 56 participants representing health and social care practitioners, policymakers, service commissioners, and voluntary and independent sectors took part in stakeholder workshops. Methods Three-phase multimethod study comprising focus group discussions, an online consultation and stakeholder workshops. Qualitative data were analysed thematically and quantitative data from the online survey were analysed using descriptive statistics. Results Study participants were concerned about the low uptake of Healthy Start vitamin supplements and the consequences of this for health outcomes for women and young children. They experienced Healthy Start vitamin distribution as logistically complex, requiring the time, resources and creative thinking of a range of local and regional practitioners from senior strategists to administrative support workers. In the light of this, many participants argued that moving to universal provision of vitamin supplements would be more cost-effective than the current system. Conclusions There is consistency of views of health practitioners that the current targeted system of providing free vitamin supplements for low-income childbearing women and young children via the Healthy Start programme is not fulfilling its potential to address vitamin deficiencies. There is wide professional and voluntary sector support for moving from the current targeted system to provision of free vitamin supplements for all pregnant and new mothers, and children up to their fifth birthday.

The U.S Geological Survey (USGS) Core Science Systems has been working for the past year to design, re-architect, and implement several key tools and systems within the USGS Cloud Hosting Service supported by Amazon Web Services (AWS). As a result of emerging USGS data management policies that align with federal Open Data mandates, and as part of a concerted effort to respond to potential increasing user demand due to these policies, the USGS strategically began migrating its core data management tools and services to the AWS environment in hopes of leveraging cloud capabilities (i.e. auto-scaling, replication, etc.). The specific tools included: USGS Online Metadata Editor (OME); USGS Digital Object Identifier (DOI) generation tool; USGS Science Data Catalog (SDC); USGS ScienceBase system; and an integrative tool, the USGS Data Release Workbench, which steps bureau personnel through the process of releasing data. All of these tools existed long before the Cloud was available and presented significant challenges in migrating, re-architecting, securing, and moving to a Cloud based environment. Initially, a `lift and shift' approach, essentially moving as is, was attempted and various lessons learned about that approach will be discussed, along with recommendations that resulted from the development and eventual operational implementation of these tools. The session will discuss lessons learned related to management of these tools in an AWS environment; re-architecture strategies utilized for the tools; time investments through sprint allocations; initial benefits observed from operating within a Cloud based environment; and initial costs to support these data management tools.

Longitudinal analysis of standardized test scores of students in the Science Writing Heuristic approach

NASA Astrophysics Data System (ADS)

Chanlen, Niphon

The purpose of this study was to examine the longitudinal impacts of the Science Writing Heuristic (SWH) approach on student science achievement measured by the Iowa Test of Basic Skills (ITBS). A number of studies have reported positive impact of an inquiry-based instruction on student achievement, critical thinking skills, reasoning skills, attitude toward science, etc. So far, studies have focused on exploring how an intervention affects student achievement using teacher/researcher-generated measurement. Only a few studies have attempted to explore the long-term impacts of an intervention on student science achievement measured by standardized tests. The students' science and reading ITBS data was collected from 2000 to 2011 from a school district which had adopted the SWH approach as the main approach in science classrooms since 2002. The data consisted of 12,350 data points from 3,039 students. The multilevel model for change with discontinuity in elevation and slope technique was used to analyze changes in student science achievement growth trajectories prior and after adopting the SWH approach. The results showed that the SWH approach positively impacted students by initially raising science achievement scores. The initial impact was maintained and gradually increased when students were continuously exposed to the SWH approach. Disadvantaged students who were at risk of having low science achievement had bigger benefits from experience with the SWH approach. As a result, existing problematic achievement gaps were narrowed down. Moreover, students who started experience with the SWH approach as early as elementary school seemed to have better science achievement growth compared to students who started experiencing with the SWH approach only in high school. The results found in this study not only confirmed the positive impacts of the SWH approach on student achievement, but also demonstrated additive impacts found when students had longitudinal experiences with the approach. By engaging in the argument-based classrooms where teachers value students' prior knowledge, encourage students to take control of their learning, and provide non-threatening environment for students to developing big ideas through negotiation, student's achievement can be enhanced. The results also started to shed some light on sustainability of the SWH approach within the school district.

We Look More, Listen More, Notice More: Impact of Sustained Professional Development on Head Start Teachers' Inquiry-Based and Culturally-Relevant Science Teaching Practices

NASA Astrophysics Data System (ADS)

Roehrig, Gillian H.; Dubosarsky, Mia; Mason, Annie; Carlson, Stephan; Murphy, Barbara

2011-10-01

Despite many scholars' recommendations, science is often avoided during early childhood education. Among the reasons provided by early childhood teachers for the exclusion of science from their daily routines included science anxiety, low self-efficacy with respect to teaching science, lack of experience participating in science activities as students, or the notion that literacy and language are more important during the early years. In minority populations the problem is even greater due to identification of science with the `culture of. This article presents results from Ah Neen Dush, a sustained and transformative professional development program for Head Start teachers on an American Indian Reservation. The goal of the program is to support early childhood teachers in developing inquiry-based and culturally-relevant teaching practices. Through analysis of teachers' classroom practices, surveys and interviews, we explore changes in teachers' attitudes toward science and inquiry-based practices. Classroom observations were conducted using CLASS (Classroom assessment Scoring System), a tool used to evaluate the quality of classroom interactions. After 1 year of professional development teachers' attitudes were found to improve and after 2 years teachers classroom practices were more inquiry-based with statistically significant increases in CLASS observation scores.

Driven by Affect to Explore Asteroids, the Moon, and Science Education

NASA Astrophysics Data System (ADS)

Dingatantrige Perera, Jude Viranga

Affect is a domain of psychology that includes attitudes, emotions, interests, and values. My own affect influenced the choice of topics for my dissertation. After examining asteroid interiors and the Moon's thermal evolution, I discuss the role of affect in online science education. I begin with asteroids, which are collections of smaller objects held together by gravity and possibly cohesion. These "rubble-pile" objects may experience the Brazil Nut Effect (BNE). When a collection of particles of similar densities, but of different sizes, is shaken, smaller particles will move parallel to the local gravity vector while larger objects will do the opposite. Thus, when asteroids are shaken by impacts, they may experience the BNE as possibly evidenced by large boulders seen on their surfaces. I found while the BNE is plausible on asteroids, it is confined to only the outer layers. The Moon, which formed with a Lunar Magma Ocean (LMO), is the next topic of this work. The LMO is due to the Moon forming rapidly after a giant impact between the proto-Earth and another planetary body. The first 80% of the LMO solidified rapidly at which point a floatation crust formed and slowed solidification of the remaining LMO. Impact bombardment during this cooling process, while an important component, has not been studied in detail. Impacts considered here are from debris generated during the formation of the Moon. I developed a thermal model that incorporates impacts and find that impacts may have either expedited or delayed LMO solidification. Finally, I return to affect to consider the differences in attitudes towards science between students enrolled in fully-online degree programs and those enrolled in traditional, in-person degree programs. I analyzed pre- and post-course survey data from the online astrobiology course Habitable Worlds. Unlike their traditional program counterparts, students enrolled in online programs started the course with better attitudes towards science and also further changed towards more positive attitudes during the course. Along with important conclusions in three research fields, this work aims to demonstrate the importance of affect in both scientific research and science education.

The SWITCH-ON Virtual Water-Science Laboratory (VWSL) aims to facilitate collaboration and support reproducible experiments in water research. The goal is to overcome geographical distance for comparative hydrology and increase transparency when using computational tools in hydrological sciences. The VWSL gives access to open data through dedicated software tools for data search and upload, and helps creating collaborative protocols for joint experiments in the virtual environment. The VWSL will help scientists with: • Cooperation around the world - straightforward connections with other scientists in comparative analyses and collaboration, as a mean to accelerate scientific advance in hydrology. • Repeatability of experiments -thorough review of a large variety of numerical experiments, which is a foundational principle in scientific research, and improvement of research standards. • New forms of scientific research - by using online 'living' protocols, scientists you can elaborate ideas incrementally with a large group of colleagues and share data, tools, models, etc. in open science. The VWSL was developed within the EU project "Sharing Water Information to Tackle Changes in Hydrology - for Operational Needs" (Grant agreement No 603587). Visitors can choose to Define, Participate or Review experiments by clicking the start buttons (http://www.switch-on-vwsl.eu/). Anyone can view protocols without log-in (that's important for Open Science) - but to create, participate and edit protocols, you need to Log-in for security reasons. During the work process, the protocol is moved from one view to another as the experiment evolves from idea, to on-going, to be completed. The users of the Lab also get access to useful tools for running collaborative experiments, for instance: Open data Search, Data (and metadata) Upload, and Create Protocol tools. So far, eight collaborative experiments have been completed in the VWSL and resulted in research papers (published or submitted), and there are currently four on-going experiments, which also involves external participants, not paid by the project. The VWSL is now launched and open to everyone but it will be continuously developed and sustained also after the project. This presentation will give an on-line demonstration of the major features of the present VWSL and discuss some future visions and major challenges in this e-infrastructure.

Dispersal of large branchiopod cysts: Potential movement by wind from potholes on the Colorado Plateau

USGS Publications Warehouse

Graham, T.B.; Wirth, D.

2008-01-01

Wind is suspected to be a primary dispersal mechanism for large branchiopod cysts on the Colorado Plateau. We used a wind tunnel to investigate wind velocities capable of moving pothole sediment and cysts from intact and disturbed surfaces. Material moved in the wind tunnel was trapped in filters; cysts were separated from sediment and counted. Undisturbed sediment moved at velocities as low as 5.9 m s-1 (12.3 miles h-1). A single all-terrain vehicle (ATV) track increased the sediment mass collected 10-fold, with particles moving at a wind velocity of only 4.2 m s-1 (8.7 miles h-1). Cysts were recovered from every wind tunnel trial. Measured wind velocities are representative of low-wind speeds measured near Moab, Utah. Wind can move large numbers of cysts to and from potholes on the Colorado Plateau. Our results indicate that large branchiopod cysts move across pothole basins at low-wind speeds; additional work is needed to establish velocities at which cysts move between potholes. ?? 2007 Springer Science+Business Media B.V.

Backfilling with guarantees granted upon job submission.

In this paper, we present scheduling algorithms that simultaneously support guaranteed starting times and favor jobs with system desired traits. To achieve the first of these goals, our algorithms keep a profile with potential starting times for every unfinished job and never move these starting times later, just as in Conservative Backfilling. To achieve the second, they exploit previously unrecognized flexibility in the handling of holes opened in this profile when jobs finish early. We find that, with one choice of job selection function, our algorithms can consistently yield a lower average waiting time than Conservative Backfilling while still providingmore » a guaranteed start time to each job as it arrives. In fact, in most cases, the algorithms give a lower average waiting time than the more aggressive EASY backfilling algorithm, which does not provide guaranteed start times. Alternately, with a different choice of job selection function, our algorithms can focus the benefit on the widest submitted jobs, the reason for the existence of parallel systems. In this case, these jobs experience significantly lower waiting time than Conservative Backfilling with minimal impact on other jobs.« less

Career moves of urban science teachers: Negotiating constancy, change, and confirmation

NASA Astrophysics Data System (ADS)

Rinke, Carol Riegelman

2007-12-01

This dissertation addresses the issue of teacher retention in urban science classrooms, in which a revolving door of new teachers leads to an inexperienced teaching force and reduced academic attainment for students. Urban science teachers are particularly susceptible to attrition due to extensive professional opportunities outside the classroom. This study follows eight case study teachers in an urban school district in order to better understand how today's urban science teachers think about their careers and career moves. Based on traditional research on teacher retention and existing literature on teachers' professional lives, this study focuses in particular on urban science teachers' professional priorities, community participation, and process of career decision making in order to determine the ways in which these factors may be consequential for their career paths. The study uses a qualitative case study methodology. Data collection methods include a survey of all first, second, and third year science teachers in one urban district followed by the selection of eight case study teachers using a variety of demographic, certification, and workplace characteristics. In-depth case studies included monthly interviews and professional observations over parts of two school years. The experiences and perspectives of the eight case study teachers revealed three patterns. First, the eight case study teachers followed two distinct paths through the profession, those who aimed to integrate and were oriented toward the educational system and those who wanted to participate and oriented themselves away from the educational system. These professional trajectories were influential in shaping case study teachers' experiences in schools as well as their career directions. Second, the eight case study teachers continually considered their professional alternatives, either within or outside of the educational system. Finally, the case study teachers aimed to get past the challenges inherent in urban teaching and reach professional confirmation before moving on to new roles and responsibilities. These themes indicate the centrality of urban science teachers' professional orientations for recruitment, preparation, and retention, demonstrate the need for in-depth and longitudinal research on teacher retention, and suggest the pivotal nature of professional growth in career mobility.

Blogging the Stories of Citizen Science to Inspire Participation, Build Community, and Increase Public Understanding of Science

2011-12-01

Sharing citizen science projects and the experiences that people have with science through blogs provides avenues to foster public understanding of science and showcase ways that people can get involved. Blogs, combined with other social media such as Twitter and Facebook, make science social - adding a human element to the process of scientific discovery. We have been sharing stories of citizen science through two blogs. Intended for a general public audience. The Science for Citizens blog (http://scienceforcitizens.net/blog/) was started in 2010 and links blog posts to a growing network of citizen science projects. Citizen Science Buzz (http://www.talkingscience.org/category/citizen-science-buzz/) was started in 2011 on the TalkingScience blog network, a project of the Science Friday Initiative. Both blogs aim to increase the exposure of citizen science projects, inspire people to do citizen science, and connect people with projects that interest them. The timeliness of blogs also provides a good platform for sharing information about one-time citizen science events and short-lived projects. Utilizing Facebook and Twitter increases traffic to blog posts about citizen science events in a timely manner and can help build community around events. Additionally, the timeliness of blogs provides the opportunity to connect citizen science and current events, helping to form geoscience teachable moments out of recent news. For example, highlighting citizen scientists near Birmingham, Alabama who collect weather data after the April 2011 tornado outbreak ravaged that area offers a positive note on how people are volunteering their time to help us all better understand the planet despite a catastrophic event.

Properties of an intergenic terminator and start site switch that regulate IMD2 transcription in yeast.

PubMed

Jenks, M Harley; O'Rourke, Thomas W; Reines, Daniel

2008-06-01

The IMD2 gene in Saccharomyces cerevisiae is regulated by intracellular guanine nucleotides. Regulation is exerted through the choice of alternative transcription start sites that results in synthesis of either an unstable short transcript terminating upstream of the start codon or a full-length productive IMD2 mRNA. Start site selection is dictated by the intracellular guanine nucleotide levels. Here we have mapped the polyadenylation sites of the upstream, unstable short transcripts that form a heterogeneous family of RNAs of approximately 200 nucleotides. The switch from the upstream to downstream start sites required the Rpb9 subunit of RNA polymerase II. The enzyme's ability to locate the downstream initiation site decreased exponentially as the start was moved downstream from the TATA box. This suggests that RNA polymerase II's pincer grip is important as it slides on DNA in search of a start site. Exosome degradation of the upstream transcripts was highly dependent upon the distance between the terminator and promoter. Similarly, termination was dependent upon the Sen1 helicase when close to the promoter. These findings extend the emerging concept that distinct modes of termination by RNA polymerase II exist and that the distance of the terminator from the promoter, as well as its sequence, is important for the pathway chosen.

A transparent, step-wise, research approach was used for informing evidence-based decisions among and for various, diverse stakeholders. A steering committee and subject-matter experts convened to devise the protocol and independent systematic reviews were performed to determine the quality of the evidence for nutritional science in 4 areas relevant to military populations: (1) caffeinated foods and beverages; (2) omega-3 polyunsaturated fatty acids; (3) plant-based foods and beverages or their phytochemical constituents; and (4) whole dietary patterns. A research expert panel was asked to then recommend future research directions and solutions likely to benefit warfighters. An implementation expert panel further considered how to apply sound nutritional science in a cost-effective manner. This article summarizes the methodological processes, high-level results, global research recommendations, and priorities for implementation. Specific results of the individual dietary interventions, as well as recommendations for moving this field of research and practice forward, are detailed throughout the current supplement. © The Author(s) 2017.

Objective: A survey was conducted of health sciences libraries to obtain information about newer buildings, additions, remodeling, and renovations. Method: An online survey was developed, and announcements of survey availability posted to three major email discussion lists: Medical Library Association (MLA), Association of Academic Health Sciences Libraries (AAHSL), and MEDLIB-L. Previous discussions of library building projects on email discussion lists, a literature review, personal communications, and the author's consulting experiences identified additional projects. Results: Seventy-eight health sciences library building projects at seventy-three institutions are reported. Twenty-two are newer facilities built within the last ten years; two are space expansions; forty-five are renovation projects; and nine are combinations of new and renovated space. Six institutions report multiple or ongoing renovation projects during the last ten years. Conclusions: The survey results confirm a continuing migration from print-based to digitally based collections and reveal trends in library space design. Some health sciences libraries report loss of space as they move toward creating space for “community” building. Libraries are becoming more proactive in using or retooling space for concentration, collaboration, contemplation, communication, and socialization. All are moving toward a clearer operational vision of the library as the institution's information nexus and not merely as a physical location with print collections. PMID:20428277
