The aim of this study was to identify the predictive factors influencing mortality in patients with bleeding Mallory-Weiss syndrome in comparison with peptic ulcer bleeding. Between January 2005 and December 2009, 281 patients with endoscopically confirmed Mallory-Weiss syndrome and 1530 patients with peptic ulcer bleeding were consecutively evaluated. The 30-day mortality and clinical outcome were related to the patients' demographic data, endoscopic, and clinical characteristics. The one-year cumulative incidence for bleeding Mallory-Weiss syndrome was 7.3 cases/100,000 people and for peptic ulcer bleeding 40.4 cases/100,000 people. The age-standardized incidence for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding remained unchanged during the observational five-year period. The majority of patients with bleeding Mallory-Weiss syndrome were male patients with significant overall comorbidities (ASA class 3-4). Overall 30-day mortality rate was 5.3% for patients with bleeding Mallory-Weiss syndrome and 4.6% for patients with peptic ulcer bleeding (p = 0.578). In both patients with bleeding Mallory-Weiss syndrome and peptic ulcer bleeding, mortality was significantly higher in patients over 65 years of age and those with significant overall comorbidities (ASA class 3-4). The incidence of bleeding Mallory-Weiss syndrome and peptic ulcer bleeding has not changed over a five-year observational period. The overall 30-day mortality was almost equal for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding and was positively correlated to older age and underlying comorbid illnesses.

Ising Critical Behavior of Inhomogeneous Curie-Weiss Models and Annealed Random Graphs

We study the critical behavior for inhomogeneous versions of the Curie-Weiss model, where the coupling constant {J_{ij}(β)} for the edge {ij} on the complete graph is given by {J_{ij}(β)=β w_iw_j/( {sum_{kin[N]}w_k})}. We call the product form of these couplings the rank-1 inhomogeneous Curie-Weiss model. This model also arises [with inverse temperature {β} replaced by {sinh(β)} ] from the annealed Ising model on the generalized random graph. We assume that the vertex weights {(w_i)_{iin[N]}} are regular, in the sense that their empirical distribution converges and the second moment converges as well. We identify the critical temperatures and exponents for these models, as well as a non-classical limit theorem for the total spin at the critical point. These depend sensitively on the number of finite moments of the weight distribution. When the fourth moment of the weight distribution converges, then the critical behavior is the same as on the (homogeneous) Curie-Weiss model, so that the inhomogeneity is weak. When the fourth moment of the weights converges to infinity, and the weights satisfy an asymptotic power law with exponent {τ} with {τin(3,5)}, then the critical exponents depend sensitively on {τ}. In addition, at criticality, the total spin {S_N} satisfies that {S_N/N^{(τ-2)/(τ-1)}} converges in law to some limiting random variable whose distribution we explicitly characterize.

The Weiss score and beyond--histopathology for adrenocortical carcinoma.

The pathological diagnosis of adrenocortical carcinoma (ACC) is still challenging for its rarity and the presence of special variants (pediatric, oncocytic, myxoid, and sarcomatoid). It is based on the recognition at light microscopy of at least three among nine morphological parameters, according to the Weiss scoring system, which has been introduced 27 years ago and nowadays is the most widely employed. Nevertheless, the diagnostic performance of this system is very high but does not reach a sensitivity and specificity of 100%, its diagnostic applicability is potentially low among non-expert pathologists, and a group of borderline cases with only one or two criteria exist of uncertain behavior. Moreover, it is scarcely reproducible in the ACC morphological variants. In fact, specifically for the pure oncocytic neoplasms that seem to have a better prognosis in comparison to the conventional ACCs, a modified system (the Lin-Weiss-Bisceglia) has been proposed. With the aim to simplify the ACC diagnosis, 2 years ago, the "reticulin" diagnostic algorithm has been proposed, based on the observation that the tumoral reticulin framework (highlighted by reticulin silver-based histochemical staining) is consistently disrupted in malignant cases but only in a small subset of benign cases. Following this algorithm, in the presence of reticulin alterations, malignancy is further defined through the identification of at least one of the following parameters: necrosis, high mitotic rate, and venous invasion. As a complement to the morphological approach, some immunohistochemical markers (such as steroidogenic factor 1) have been proposed as diagnostic and prognostic adjuncts but still lack wide clinical validation.

2011-12-01

After Hurricane Katrina devastated Gulf Coast homes in 2005, Oakcrest High School science teacher and geologist, Dave Jungblut, traveled from Gulfport to Ocean Springs, Mississippi and conducted research to determine whether property damage was caused by wind or water. Jungblut wrote several studies, " Katrina Straight- Line Wind Field Study", "Applying Research to Practical Use for Hurricane Katrina Homeowners", and "Hurricane Katrina Wind Study" proving wind damage. Jungblut's research, done pro bono, helped thousands of homeowner's in the Mississippi area be reimbursed by insurance companies for wind damage caused by Hurricane Katrina http://www.hurricanekatrinastudy.com/ Jungblut incorporated his extensive data, in a high school curriculum that is now part of the science program he teaches each year. In January 2010, Jungblut presented "Hurricane Forensics" curriculum at the Rutgers Center for Mathematics, Science and Computer January 2009 Workshop http://www.dimacs.rutgers.edu/wst/. Through labs and creative hands-on activities, Jungblut challenged his students to analyze the photographic evidence, and data he collected, for themselves. Jungblut taught his students how to use geologic and forensic inquiry techniques to discover the difference between straight-line winds from microburst activity. The students applied the concept of the Geological Principle of Relative Dating, to determine the sequence of events that happened during Hurricane Katrina. They built model structures, which were subjected to wind and water forces to better understand the effects of these phenomena, Finally, the students evaluated local and worldwide environmental issues, such as land use risks and benefits, in the face of global warming, In the spring of 2010 when the BP Oil Spill occurred, Jungblut realized, another opportunity to bring real world issues into the classroom. After exploring scientific concepts relating to this environmental crisis, Jungblut challenged his students to

We study here the magnetic properties of Y- and Lu- Iron Garnets using the Bethe- Peierls-Weiss method modified to suit complex systems like these Garnets. We consider these Garnets as described by Heisenberg Hamiltonian with two sublattices (a,d) and determine the exchange interaction parameters Jad, Jaa and Jdd by matching the exerimental susceptibility curves. We find Jaa and Jdd to be much smaller than those determined by Néel theory, and consistent with those obtained by the study of spin wave spectra; the spin wave dispersion relation constant obtained using these parameters gives good agreement with the experimental values.

General Atomics Aeronautical Systems, Inc., is developing the Altair version of its Predator B unmanned reconnaissance aircraft under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project. NASA plans to use the Altair as a technology demonstrator to validate a variety of command and control technologies for UAVs, as well as demonstrate the capability to perform a variety of Earth science missions. The Altair is designed to carry an 700-lb. payload of scientific instruments and imaging equipment for as long as 32 hours at up to 52,000 feet altitude. Eleven-foot extensions have been added to each wing, giving the Altair an overall wingspan of 86 feet with an aspect ratio of 23. It is powered by a 700-hp. rear-mounted TPE-331-10 turboprop engine, driving a three-blade propeller. Altair is scheduled to begin flight tests in the fourth quarter of 2002, and be acquired by NASA following successful completion of basic airworthiness tests in early 2003 for evaluation of over-the-horizon control, detect, see and avoid and other technologies required to allow UAVs to operate safely with other aircraft in the national airspace.

Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis. Clinical and radiological findings were concordant with Müller-Weiss disease, which is a rare disease with complex idiopathic foot condition of the adult tarsal navicular bone characterized by progressive navicular fragmentation and talonavicular joint destruction. The patient was successfully treated with two-staged bilateral talonavicular arthrodesis.

2018-04-01

This paper proposes a conditional Curie-Weiss model as a model for decision making in a stylized society made up of binary decision makers that face a particular dichotomous choice between two options. Following Brock and Durlauf (Discrete choice with social interaction I: theory, 1955), we set-up both socio-economic and statistical mechanical models for the choice problem. We point out when both the socio-economic and statistical mechanical models give rise to the same self-consistent equilibrium mean choice level(s). Phase diagram of the associated statistical mechanical model and its socio-economic implications are discussed.

System approaches of Weiss and Bertalanffy and their relevance for systems biology today.

PubMed

Drack, Manfred; Wolkenhauer, Olaf

2011-06-01

System approaches in biology have a long history. We focus here on the thinking of Paul A. Weiss and Ludwig von Bertalanffy, who contributed a great deal towards making the system concept operable in biology in the early 20th century. To them, considering whole living systems, which includes their organisation or order, is equally important as the dynamics within systems and the interplay between different levels from molecules over cells to organisms. They also called for taking the intrinsic activity of living systems and the conservation of system states into account. We compare these notions with today's systems biology, which is often a bottom-up approach from molecular dynamics to cellular behaviour. We conclude that bringing together the early heuristics with recent formalisms and novel experimental set-ups can lead to fruitful results and understanding. Copyright © 2011 Elsevier Ltd.

Asymptotic densities from the modified Montroll-Weiss equation for coupled CTRWs

NASA Astrophysics Data System (ADS)

Aghion, Erez; Kessler, David A.; Barkai, Eli

2018-01-01

We examine the bi-scaling behavior of Lévy walks with nonlinear coupling, where χ, the particle displacement during each step, is coupled to the duration of the step, τ, by χ τβ. An example of such a process is regular Lévy walks, where β = 1. In recent years such processes were shown to be highly useful for analysis of a class of Langevin dynamics, in particular a system of Sisyphus laser-cooled atoms in an optical lattice, where β = 3/2. We discuss the well-known decoupling approximation used to describe the central part of the particles' position distribution, and use the recently introduced infinite-covariant density approach to study the large fluctuations. Since the density of the step displacements is fat-tailed, the last travel event must be treated with care for the latter. This effect requires a modification of the Montroll-Weiss equation, an equation which has proved important for the analysis of many microscopic models.

Dave worked on scientific space instrumentation since the Apollo era in the mid-1960s. He was born and raised in Milwaukee, WI, and attended Milwaukee Lutheran High School where he built a Michelson interferometer that proved to be a stepping-stone for his interest in physics. Dave graduated from the University of Wisconsin-Madison, where he earned a Bachelor of Science in applied mathematics and engineering physics in 1967. As an undergraduate, he worked on balloon-launched sounding rockets and scientific instruments in X-ray and gamma-ray astronomy. At Cornell University, Dave earned a master's degree in 1971, and a doctorate in 1972, both in physics. He built a balloon-borne gamma-ray telescope that detected the first pulsed high-energy gamma rays from the Crab pulsar. In 1972, Dave began his career at American Science and Engineering where he was the project scientist for the Uhuru X-ray satellite. Later, he served as the project scientist for the development of the Einstein Observatory. Dave joined the Smithsonian Center for Astrophysics in 1977 as the project scientist for the Spacelab-2 infrared telescope. There, he served as a co-investigator on the Space Infrared Telescope Facility - IRAC camera proposal, and co-investigator on the Submillimeter Wave Astronomy Satellite, which launched in December 1998. Dave came to NASA Ames Research Center to lead the mission operations for SIRTF and SOFIA (Stratospheric Observatory for Infrared Astronomy) in 1988. He created the Flight Opportunities for Science Teacher EnRichment project. In 1992, Dave began working on what has become the Kepler mission, for which he served as deputy principal investigator until retiring in August 2011. Dave's contributions were many but most notably, he led the development of the Kepler Technology Demonstration used to prove that the transit photometry method would work under on-orbit conditions. Dave loved to build things and was passionate about engaging young hearts and minds with

Data science implications in diamond formation and craton evolution

NASA Astrophysics Data System (ADS)

Pan, F.; Huang, F.; Fox, P. A.

2017-12-01

Diamonds are so-called "messengers" from the deep Earth. Fluid and mineral inclusions in diamonds could reflect the compositions of fluids/melts and wall-rocks in which diamond formed. Recently many diamond samples are examined to study the water content in the mantle transition zone1, the mechanism of diamond formation2 and the mantle evolution history3. However, most of the studies can only explain local activities. Therefore, an overall project of data grouping, comparison and correlation is needed, but limited progress has been made due to a lack of benchmark datasets on diamond formation and effective computing algorithms. In this study, we start by proposing the very first complete and easily-accessible dataset on mineral and fluid inclusions in diamonds. We rescue, collect and organize the data available from papers, journals and other publications resources ([2-4] and more), and then apply several state-of-the-art machine learning methods to tackle this earth science problem by clustering diamond formation process into distinct groups primarily based on the compositions, the formation temperature and pressure, the age and so on. Our ongoing work includes further data exploration and training existing models. Our preliminary results show that diamonds formed from older cratons usually have higher formation temperature. Also peridotitic diamonds take a much larger population than the ecologitic ones. More details are being discovered when we finish constructing the database and training our model. We expect the result to demonstrate the advantages of using machine learning and data science in earth science research problems. Our methodology for knowledge discovery are very general and can be broadly applied to other earth science research problems under the same framework.[1] Pearson et al, Nature (2014); [2] Tomlinson et al, EPSL (2006); [3] Weiss et al, Nature (2016); [4] Stachel and Harris, Ore Geology Reviews (2008); Weiss et al, EPSL (2013)

c-Axis oriented epitaxial Ba 0.25Sr 0.75TiO 3 films display Curie-Weiss behavior

Thin films of ferroelectrics have inferior dielectric properties, including microwave losses, compared to bulk material and generally do not display a proper Curie-Weiss behavior. This study shows that the film properties can be improved considerably, with a Curie-Weiss behavior, by choosing lattice matched electrodes and proper stoichiometry. A 700 nm thick Ba 0.25Sr 0.75TiO 3 layer was inserted, by laser ablation, between two epitaxial metallic oxide (200 nm) SrRuO 3 electrodes. Because of compressive stress in the plane of the substrate, the c-axis of the unit cell in the Ba 0.25Sr 0.75TiO 3 layer was normal to the substrate plane. Grains were of the order of 100-200 nm (with small misorientation angles in a× b plane) as determined by X-rays and AFM. The positions of pronounced maxima in the temperature dependence of the permittivity depended on external bias voltage applied between the SrRuO 3 electrodes to the dielectric film. The measured ε( T) curves agreed well with existing theoretical models at temperatures below and above the ferroelectric phase transition point. At T≈200 K, ε/ ε0 for the Ba 0.25Sr 0.75TiO 3 layer was suppressed up to 85% (from 4400 down to 560) when ±2.5 V bias voltage was applied to the metallic oxide electrodes. Well saturated polarization-vs.-voltage hysteresis loops were measured for the Ba 0.25Sr 0.75TiO 3 layer in the temperature interval 4.2-200 K. Because of depolarization effects, the polarization of the Ba 0.25Sr 0.75TiO 3 layer was suppressed at positive voltage applied between the electrodes, as compared with a negative one.

We generalize the Wilemski-Fixman-Weiss decoupling approximation to calculate the transient rate of absorption of point particles into multiple sinks of different sizes, shapes, and reactivities. As an application we consider the case involving two spherical sinks. We obtain a Laplace-transform expression for the transient rate that is in excellent agreement with computer simulations. The long-time steady-state rate has a relatively simple expression, which clearly shows the dependence on the diffusion constant of the particles and on the sizes and reactivities of sinks, and its numerical result is in good agreement with the known exact result that is given in terms of recursion relations.

In this article, we review how two eminent Viennese system thinkers, Paul A Weiss and Ludwig von Bertalanffy, began to develop their own perspectives toward a system theory of life in the 1920s. Their work is especially rooted in experimental biology as performed at the Biologische Versuchsanstalt, as well as in philosophy, and they converge in basic concepts. We underline the conceptual connections of their thinking, among them the organism as an organized system, hierarchical organization, and primary activity. With their system thinking, both biologists shared a strong desire to overcome what they viewed as a "mechanistic" approach in biology. Their interpretations are relevant to the renaissance of system thinking in biology--"systems biology." Unless otherwise noted, all translations are our own.

Dave Eggers's a heartbreaking work of staggering genius: memoir as a "pain-relief device".

PubMed

Miller, Elise

2011-10-01

Dave Eggers's memoir is an important addition to the tradition of autobiography in America, and offers significant contributions to our understanding of creativity, sublimation, and the psychology of the memoir-writing process. A Heartbreaking Work of Staggering Genius is really two books--an autobiographical narrative about unbearable suffering, and a book of psychoanalytic commentary on the challenges of writing a memoir about catastrophic loss and trauma. The main narrative suggests the psychological resilience it takes to contain unbearable suffering. The metanarrative renders transparent the mind of someone who is both remembering his losses and constantly reflecting upon the process of writing about them. Eggers's identification with authorship, rather than bereavement or traumatization, may have played an important role in containing his affect and his sense of self when the heartbreaking events were originally unfolding. But a price is paid when a son uses his art to construct a new identity as an author--unconscious conflicts, primitive affect, anxieties about failing, as well as guilt about succeeding--consequences often missed by readers. Heartbreaking is a palimpsest, a story about story-telling superimposed on tales of death and survival, but its messages will be missed unless all its parts are preserved when being read or studied.

The influence of David Keeling on oceanic CO2 measurements

NASA Astrophysics Data System (ADS)

Brewer, Peter G.

Dave Keeling—only Roger Revelle called him "Charles David" and always in a tone that could command Dave's attention—had a remarkable influence on the creation of modern understanding of the oceanic CO2 system. Although Dave resided at an oceanographic institution for almost his entire professional career, the great majority of his work concerned atmospheric measurements; his own account of his work [Keeling, 1998] makes scant reference to his ocean science papers. But those relatively few oceanic papers, and more importantly his intense personal interest and unimpeachable reputation for classic measurement, had enormous impact. It is possible to trace Dave's influence on oceanic measurement through the course of five decades, and over that time, our understanding has grown enormously. The following is a somewhat personal account, but Dave so influenced the careers of the small group of ocean CO2 scientists that have led the way that any one of them would write a similar account.

Combined use of clips and nylon snare ("tulip-bundle") as a rescue endoscopic bleeding control in a mallory-weiss syndrome.

Mallory-Weiss syndrome (MWS) accounts for 6-14% of all cases of upper gastrointestinal bleeding. Prognosis of patients with MWS is generally good, with a benign course and rare recurrence of bleeding. However, no strict recommendations exist in regard to the mode of action after a failure of primary endoscopic hemostasis. We report a case of an 83-year-old male with MWS and rebleeding after the initial endoscopic treatment with epinephrine and clips. The final endoscopic control of bleeding was achieved by a combined application of clips and a nylon snare in a "tulip-bundle" fashion. The patient had an uneventful postprocedural clinical course and was discharged from the hospital five days later. To the best of our knowledge, this is the first case report showing the "tulip-bundle" technique as a rescue endoscopic bleeding control in the esophagus.

This work reports an attempt to quantify the purities of powders of high-purity organic compounds with stable nitroxyl radicals (namely, 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO), 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine (TEMPOL), and 4-hydroxy-2,2,6,6-tetramethylpiperidine 1-oxyl benzoate (4-hydroxy-TEMPO benzoate)) in terms of mass fractions by using our “effective magnetic moment method,” which is based on both the Curie–Weiss law and a fundamental equation of electron paramagnetic resonance (ESR). The temperature dependence of the magnetic moment resulting from the radicals was measured with a superconducting quantum interference device magnetometer. The g value for each compound was measured with an X-band ESR spectrometer. The results of the purities were (0.998 ± 0.064) kg kg{supmore » −1} for TEMPO, (1.019 ± 0.040) kg kg{sup −1} for TEMPOL, and (1.001 ± 0.048) kg kg{sup −1} for 4-hydroxy-TEMPO benzoate. These results demonstrate that this analytical method as a future candidate of potential primary direct method can measure the purities with expanded uncertainties of approximately 5%.« less

Adolescents' goal orientations for science in single-gender Israeli religious schools

Fortus, David; Daphna, Limor

2017-01-01

Israeli students and their families can choose between state-funded secular, religious, orthodox, and other alternative schools (e.g., Waldorf, Montessori, democratic). Earlier studies showed that the motivation to engage with science differs greatly between Israeli students in secular schools and democratic schools, with these differences being attributed to differences in school culture rather than home influence (Vedder-Weiss & Fortus, 2011, 2012). In this study we extend earlier studies by looking at religious state-funded schools that serve 18% of Israel's Jewish population. These schools provide a unique research environment since from grade 6 they are gender-separated. We examined the science-related mastery, performance-approach, and performance-avoid goal orientations, perceptions of the science teachers, parents, schools, and peers' goal emphases in relation to science of the students in these schools. We compared between students in religious schools (newly collected data) and secular schools (data reported in prior studies), and found that there is a distinct difference between these two populations that is associated with differing attitudes toward gender and science at these schools. This study provides additional evidence for the influence of culture on students' motivation to engage with science, suggests mechanisms by which this influence may occur.

The TeXas Earth and Space Science (TXESS) Revolution, a professional development program for 8th- thru 12th-grade Earth Science teachers, presented a one-week Petroleum Science and Technology Institute at The University of Texas at Austin campus. The summer program was a joint effort between the Jackson School of Geosciences and the Department of Petroleum and Geosystems Engineering. The goal of the institute was to focus on the STEM components involved in the petroleum industry and to introduce teachers to the larger energy resources theme. The institute kicked off with a welcoming event and tour of a green, energy-efficient home (LEED Platinum certified) owned by one of the petroleum engineering faculty. Tours of the home included an introduction to rainwater harvesting, solar energy, sustainable building materials and other topics on energy efficiency. Classroom topics included drilling technology (including a simulator lab and an overview of the history of the technology), energy use and petroleum geology, well-logging technology and interpretation, reservoir engineering and volumetrics (including numerous labs combining chemistry and physics), risk assessment and economics, carbon capture and storage (CO2 sequestration technology) and hydraulic fracturing. A mid-week field trip included visiting the Ocean Star offshore platform in Galveston, the Weiss Energy Hall at the Houston Museum of Science and Schlumberger (to view 3-D visualization technology) in Houston. Teachers remarked that they really appreciated the focused nature of the institute and especially found the increased use of mathematics both a tool for professional growth, as well as a challenge for them to use more math in their science classes. STEM integration was an important feature of the summer institute, and teachers found the integration of science (earth sciences, geophysics), technology, engineering (petroleum, chemical and reservoir) and mathematics particularly valuable.

The AURORA sensor slated for flight on the NPOESS satellites represents the culmination of over 20 years of experience at JHU/APL in the design, manufacture, flight, operation and analysis of compact, cost-effective far ultraviolet sensors for space weather data collection. The far ultraviolet covers the spectral range from about 115 to 185 nm. This region is ideal for observations of the upper atmosphere because, at these wavelengths, the lower atmosphere and Earth's surface are black. AURORA will observe the mid- and low-latitude F-region ionosphere, the auroral E-region ionosphere, the day thermosphere composition, auroral energy deposition and map ionospheric irregularities. AURORA implements the flight-proven design derived from SSUSI on the DMSP Block 5D spacecraft and GUVI on the NASA TIMED spacecraft. These instruments have provided the instrument and algorithm heritage for NPOESS/AURORA. In this talk the performance capabilities of the AURORA instrument will be summarized along with the design of the instrument and algorithms. Example products will be shown for each of the measurement regimes. We acknowldge support from DMSP and NASA and the collaboration with our science colleagues at the Aerospace Corporation (Paul Straus, Jim Hecht, Dave McKenzie, and Andy Christensen) and Computational Physics (Doug Strickland, Hal Knight, and Scott Evans) and Naval Research Laboratory (Robert Meier, Mike Picone, Stefan Thonnard, Pat Dandenault, and Andy Stefan) and our colleagues at APL (Michele Weiss, Doug Holland, Bill Wood, and Jim Eichert) among others.

A content analysis of sixth-grade, seventh-grade, and eighth-grade science textbooks with regard to the nature of science

NASA Astrophysics Data System (ADS)

Phillips, Marianne C.

Science teachers rely heavily on their textbooks; for many, it is the only curriculum they use (Weiss, 1993). Therefore, it is important these materials convey an accurate conception of the nature of science. Science for All Americans (AAAS, 1990) and the National Science Education Standards (NRC, 1996) call for teaching students about the nature of science. Including the nature of science throughout science textbooks will produce scientifically literate citizens (Driver and others, 1993) with an improved ability to make informed decisions (McComas, 1998). Teaching the nature of science supports the successful learning of science content and process (Driver and others, 1996), and bridges the gap between the two cultures of practicing scientists and school science (Sorsby, 2000). Do middle school science textbooks provide a balanced presentation of the nature of science throughout their text? To determine the answer, this investigation used a content analysis technique to analyze a random sample from the introduction chapter and the rest of the textbook chapters from twelve middle school science textbooks for the four aspects of the nature of science (Chiappetta, Fillman, & Sethna, 2004). Scoring procedures were used to determine interrater agreement using both Cohen's kappa (kappa) and Krippendorff's alpha (alpha). Kappa values were determined to be fair to excellent beyond chance among the three coders. The resulting values for Krippendorff's alpha ranged from acceptable (alpha > .80) to unacceptable (alpha < .67). The results from this content analysis indicated little change from previous studies in the balance for the themes of the nature of science. This investigation found the sixth-grade, seventh-grade, and eighth-grade science textbooks adopted by Texas to have unbalanced presentations for the four aspects of the nature of science. In addition, it found these middle school science textbooks are not balanced across programs. This imbalance is providing

To explore the distribution of nonperfusion area (NPA) in eyes with diabetic macular edema (DME) and its relationship with the severity of DME. Prospective, observational case series. Forty eyes of 29 patients with treatment-naïve DME who participated in the DAVE study (NCT01552408) were included. Ultra-widefield fluorescein angiography images were sent to the Doheny Image Reading Center, where they were montaged and corrected using stereographic projection to adjust for peripheral distortion. Two experienced, independent/masked certified graders manually segmented the NPA and the total visible retinal area (TRA), and computed the NPA and TRA in square millimeters (mm 2 ). The ischemic index (ISI) was calculated. The distributions of NPA and ISI within different retinal zones were correlated with the severity of DME. In 40 eyes with treatment-naïve DME (mean age, 55.8 years) visual acuity (VA) (mean 59.6 EDTRS letters) was correlated with central macular thickness (CMT) (mean 536.9 μm, R = -0.418, P = .008) and macular volume (MV) (mean 11.9 mm 3 , R = -0.449, P = .004). The NPA and ISI among the different retinal zones were significantly different (NPA: P < .001; ISI: P = .005). The NPA and ISI in the midperiphery were negatively associated with CMT (NPA: P = .04; ISI: P = .02). However, the global NPA and ISI for the entire retina were not associated with CMT or MV (P > .05). In eyes with DME, the ISI increases with increasing distance from the fovea. The severity of DME does not appear to correlate with global NPA and ISI. Copyright © 2017 Elsevier Inc. All rights reserved.

Distinctive aspects of peptic ulcer disease, Dieulafoy's lesion, and Mallory-Weiss syndrome in patients with advanced alcoholic liver disease or cirrhosis

AIM: To systematically review the data on distinctive aspects of peptic ulcer disease (PUD), Dieulafoy’s lesion (DL), and Mallory-Weiss syndrome (MWS) in patients with advanced alcoholic liver disease (aALD), including alcoholic hepatitis or alcoholic cirrhosis. METHODS: Computerized literature search performed via PubMed using the following medical subject heading terms and keywords: “alcoholic liver disease”, “alcoholic hepatitis”,“ alcoholic cirrhosis”, “cirrhosis”, “liver disease”, “upper gastrointestinal bleeding”, “non-variceal upper gastrointestinal bleeding”, “PUD”, ‘‘DL’’, ‘‘Mallory-Weiss tear”, and “MWS’’. RESULTS: While the majority of acute gastrointestinal (GI) bleeding with aALD is related to portal hypertension, about 30%-40% of acute GI bleeding in patients with aALD is unrelated to portal hypertension. Such bleeding constitutes an important complication of aALD because of its frequency, severity, and associated mortality. Patients with cirrhosis have a markedly increased risk of PUD, which further increases with the progression of cirrhosis. Patients with cirrhosis or aALD and peptic ulcer bleeding (PUB) have worse clinical outcomes than other patients with PUB, including uncontrolled bleeding, rebleeding, and mortality. Alcohol consumption, nonsteroidal anti-inflammatory drug use, and portal hypertension may have a pathogenic role in the development of PUD in patients with aALD. Limited data suggest that Helicobacter pylori does not play a significant role in the pathogenesis of PUD in most cirrhotic patients. The frequency of bleeding from DL appears to be increased in patients with aALD. DL may be associated with an especially high mortality in these patients. MWS is strongly associated with heavy alcohol consumption from binge drinking or chronic alcoholism, and is associated with aALD. Patients with aALD have more severe MWS bleeding and are more likely to rebleed when compared to non

Rosage, David; Meeson, Blanche W. (Technical Monitor)

2001-01-01

It has been well recognized that the commercial remote sensing industry will expand in new directions, resulting in new applications, thus requiring a larger, more skilled workforce to fill the new positions. In preparation for this change, NASA has initiated a Remote Sensing Professional Development Program to address the workforce needs of this emerging industry by partnering with the private sector, academia, relevant professional societies, and other R&D organizations. Workforce needs will in part include understanding current industry concerns, personnel competencies, current and future skills, growth rates, geographical distributions, certifications, and sources of pre-service and in-service personnel. Dave Rosage of the NASA Goddard Space Flight Center and a panel of MAPPS members will lead a discussion to help NASA specifically address private firms' near and long-term personnel needs to be included in NASA's Remote Sensing Professional Development Program. In addition, Dave Rosage will present perspectives on how remote sensing technologies are evolving, new NASA instruments being developed, and what future workforce skills are expected to support these new developments.

remained until 1970. Here Dave's strong personal interest in the students became evident. During each year's spring break, he and Beth led a car caravan of interested astronomy and physics students to Death Valley for primitive camping, exploring the desert, studying the stars, and shooting off rockets. Beth organized all the food and Dave cooked the breakfasts, with French toast being his specialty. This tradition was so popular that many students returned year after year, long after having left the college. Dave enjoyed leading the astronomy club at Whittier College, and also participated in a municipal astronomy club. In the sixties, in addition to his job at the college, Dave worked part time at the Space Science Laboratory of North American Aviation (later North American Rockwell and now Boeing). Dave co-authored, with Gary Mc Cue and others, several papers on orbital rendezvous techniques, a capability of prime interest to the Apollo program. Soon apparent, however, was Dave's interest in the hundreds of asteroids whose orbits were known at the time. In his spare time he punched their orbital elements into computer cards and initiated a long career of searching for opportunities for spacecraft to flyby or rendezvous with one of these minor planets. He learned enough Russian to read books important at the time on the subject of asteroid orbits. In 1966 he had enough data to publish a paper on some possible asteroid encounters by human missions to Mars. Through conferences of the American Astronautical Society, Dave became acquainted with Roger Bourke, the group supervisor of the Advanced Projects Group at the Jet Propulsion Laboratory (JPL), which is managed by Caltech for NASA. In 1970, Dave retired from Whittier College and began working full time for Roger at JPL. JPL was still working on missions to the inner planets and was starting to develop missions to the outer planets. Roger understood the potential of having Dave pursue his interest in the small bodies and

Phase transition hysteresis and anomalous Curie-Weiss behavior of ferroelectric tetragonal tungsten bronzes Ba2RETi2Nb3O15:RE=Nd,Sm

The ferroelectric tetragonal tungsten bronze (TTB) phases, Ba2RETi2Nb3O15:RE=Nd,Sm, were prepared by low temperature solvothermal synthesis. The permittivity versus temperature data of sintered ceramics show two unusual features: first, a hysteresis of 50-100 °C between values of the Curie temperature Tc on heat-cool cycles and second: a huge depression in the Curie-Weiss temperature T0. Both effects are attributed to the complex nature of their TTB-related crystal structures with different superstructures above and below Tc and the difficulty in nucleating ferroelectric domains on cooling through Tc. Several factors may contribute to the latter difficulty: first, the structures contain two sets of crystallographic sites for the "active" Ti, Nb ions; second, the distribution of Ti and Nb over these two sets of sites is not random but partially ordered; and third, below Tc a weak commensurate superstructure perpendicular to the polar c&barbelow; axis is present, but above Tc a weak incommensurate superstructure in a similar orientation is present. Hence the formation of the ferroelectric structure on cooling requires both nucleation of polar domains involving two sets of cation sites and structural change from an incommensurate to a commensurate supercell.

The Weiss Functional Impairment Rating Scale-Parent Form for assessing ADHD: evaluating diagnostic accuracy and determining optimal thresholds using ROC analysis.

PubMed

Thompson, Trevor; Lloyd, Andrew; Joseph, Alain; Weiss, Margaret

2017-07-01

The Weiss Functional Impairment Rating Scale-Parent Form (WFIRS-P) is a 50-item scale that assesses functional impairment on six clinically relevant domains typically affected in attention-deficit/hyperactivity disorder (ADHD). As functional impairment is central to ADHD, the WFIRS-P offers potential as a tool for assessing functional impairment in ADHD. These analyses were designed to examine the overall performance of WFIRS-P in differentiating ADHD and non-ADHD cases using receiver operating characteristics (ROC) analysis. This is the first attempt to empirically determine the level of functional impairment that differentiates ADHD children from normal controls. This observational study comprised 5-19-year-olds with physician-diagnosed ADHD (n = 476) and non-ADHD controls (n = 202). ROC analysis evaluated the ability of WFIRS-P to discriminate between ADHD and non-ADHD, and identified a WFIRS-P cut-off score that optimises correct classification. Data were analysed for the complete sample, for males versus females and for participants in two age groups (5-12 versus 13-19 years). Area under the curve (AUC) was 0.91 (95% confidence interval 0.88-0.93) for the overall WFIRS-P score, suggesting highly accurate classification of ADHD distinct from non-ADHD. Sensitivity (0.83) and specificity (0.85) were maximal for a mean overall WFIRS-P score of 0.65, suggesting that this is an appropriate threshold for differentiation. DeLong's test found no significant differences in AUCs for males versus females or 5-12 versus 13-19 years, suggesting that WFIRS-P is an accurate classifier of ADHD across gender and age. When assessing function, WFIRS-P appears to provide a simple and effective basis for differentiating between individuals with/without ADHD in terms of functional impairment.

Health care public reporting utilization - user clusters, web trails, and usage barriers on Germany's public reporting portal Weisse-Liste.de.

Quality of care public reporting provides structural, process and outcome information to facilitate hospital choice and strengthen quality competition. Yet, evidence indicates that patients rarely use this information in their decision-making, due to limited awareness of the data and complex and conflicting information. While there is enthusiasm among policy makers for public reporting, clinicians and researchers doubt its overall impact. Almost no study has analyzed how users behave on public reporting portals, which information they seek out and when they abort their search. This study employs web-usage mining techniques on server log data of 17 million user actions from Germany's premier provider transparency portal Weisse-Liste.de (WL.de) between 2012 and 2015. Postal code and ICD search requests facilitate identification of geographical and treatment area usage patterns. User clustering helps to identify user types based on parameters like session length, referrer and page topic visited. First-level markov chains illustrate common click paths and premature exits. In 2015, the WL.de Hospital Search portal had 2,750 daily users, with 25% mobile traffic, a bounce rate of 38% and 48% of users examining hospital quality information. From 2013 to 2015, user traffic grew at 38% annually. On average users spent 7 min on the portal, with 7.4 clicks and 54 s between clicks. Users request information for many oncologic and orthopedic conditions, for which no process or outcome quality indicators are available. Ten distinct user types, with particular usage patterns and interests, are identified. In particular, the different types of professional and non-professional users need to be addressed differently to avoid high premature exit rates at several key steps in the information search and view process. Of all users, 37% enter hospital information correctly upon entry, while 47% require support in their hospital search. Several onsite and offsite improvement options are

mind, have become successful experimental philosophers. Are these issues native only to behavioral science? Earlier, I laid at Skinner's door much of the blame for an unreasonable complacency regarding the disposition of modern behavioral science. In all fairness to Skinner, however, it is only correct to acknowledge that the same problem is evident in other areas of science. Skinner appears to be a spokesman, in the behavioral sciences, for one of those famous "Zeitgeists." Let me quote a series of observations by Paul Weiss, a biologist at the Rockefeller Institute, New York City, from a paper entitled "Experience and experiment in biology" (5): Without imagination one can contrive infinite variations of experimental set-ups, all of them novel, yet utterly uninteresting, inconsequential, insignificant. The mere fact that something has not been done or tried before is not sufficient reason for doing or trying it. . . . But is not scientific history full of instances of accidental discovery of the unexpected? True again, but he who does expect something will be on the alert even for the unexpected, while he who just ambles, looking for nothing in particular, is prone to miss even the obvious. . . . We see instruments turning from servants into tyrants, forcing the captive scientist to mass-produce and market senseless data beyond the point of conceivable usefulness-a modern version of the Sorcerer's Apprentice. . . . Finally, I recommend study of N. W. Storer's article "The coming changes in American science" (6). Storer, a sociologist at Harvard University, feels that prior to 1940 the basic currency in science was professional recognition. This in turn reinforced certain fundamental values-a high emphasis on communication; dedication of the individual and a tendency to work in small, select groups; a spurning of worldly gain and a proclivity for basic research. Today, professional recognition is being replaced by more common currencies-money, power, and worldly

Extensions to the Dynamic Aerospace Vehicle Exchange Markup Language

NASA Technical Reports Server (NTRS)

Brian, Geoffrey J.; Jackson, E. Bruce

2011-01-01

The Dynamic Aerospace Vehicle Exchange Markup Language (DAVE-ML) is a syntactical language for exchanging flight vehicle dynamic model data. It provides a framework for encoding entire flight vehicle dynamic model data packages for exchange and/or long-term archiving. Version 2.0.1 of DAVE-ML provides much of the functionality envisioned for exchanging aerospace vehicle data; however, it is limited in only supporting scalar time-independent data. Additional functionality is required to support vector and matrix data, abstracting sub-system models, detailing dynamics system models (both discrete and continuous), and defining a dynamic data format (such as time sequenced data) for validation of dynamics system models and vehicle simulation packages. Extensions to DAVE-ML have been proposed to manage data as vectors and n-dimensional matrices, and record dynamic data in a compatible form. These capabilities will improve the clarity of data being exchanged, simplify the naming of parameters, and permit static and dynamic data to be stored using a common syntax within a single file; thereby enhancing the framework provided by DAVE-ML for exchanging entire flight vehicle dynamic simulation models.

LLNL science communicator Maren Hunsberger takes us "Inside the Lab" to learn about the iChip (In-vitro Chip-based Human Investigational Platform) project at Lawrence Livermore National Laboratory. "One application of the iChip system would be to develop new pharmaceutical drugs," explains Dave Soscia, LLNL postdoc. "When you test in a mouse for example, it's not as close to the human system as you can get. If we can take human cells and put them on devices and actually mimic the structure and function of the organ systems in the human, we can actually replace animal testing and even make a better system for testing pharmaceutical drugs."

Fritz Haber (1868-1934) was a German physical chemist. Nobel laureate and foreign member of the US National Academy of Sciences. His greatest accomplishment in science was the development of a practical method to prepare nitrogen from air (nitrogen fixation or Haber-Bosch process). While working on the toxicity of war gases. he formulated 'Haber's rule', also known as C x T= constant in order to characterize the toxicity of an inhalant. Between 1919 and 1933. he was one of the leading figures in revitalizing science in Germany. At his institute in Berlin worked such luminaries as Albert Einstein, Lise Meitner and Otto Hahn. His last paper described what became known as the Haber-Weiss reaction. After his death he was for a long time forgotten by the Nazis because he was Jewish and after World War II by the Allies because of his work on war gases in World War I. And yet he was one of the truly great modern scientists. not only because of his science, but also because of the role he played in science politics and policies.

Magnetization and transport properties of single RPd2P2 (R=Y, La-Nd, Sm-Ho, Yb)

NASA Astrophysics Data System (ADS)

Drachuck, Gil; Boehmer, Anna; Bud'Ko, Sergey L.; Canfield, Paul

Single crystals of RPd2P2 (R=Y, La-Nd, Sm-Ho, Yb) were grown using a self-flux method and were characterized by room-temperature powder X-ray diffraction, anisotropic temperature and field dependent magnetization and temperature dependent in-plane resistivity. Anisotropic magnetic properties, arising mostly from crystal electric field (CEF) effects, were observed for most magnetic rare earths. The experimentally estimated CEF parameters B02 were calculated from the anisotropic paramagnetic θab and θcvalues. Ordering temperatures, as well as the polycrystalline averaged paramagnetic Curie-Weiss temperature, θave, were extracted from magnetization and resistivity measurements. Work done at Ames Laboratory was supported by US Department of Energy, Basic Energy Sciences, Division of Materials Sciences and Engineering under Contract No. DE-AC02-07CH111358.

Sophisticated calculations of how planetesimals assembled into the terrestrial planets can be tested by using models of the chemistry of the solar nebula. Jade Bond (previously at University of Arizona and now at the Planetary Science Institute, Tucson, AZ), Dante Lauretta (University of Arizona) and Dave O'Brien (Planetary Sciences Institute) combined planetary accretion simulations done by O'Brien, Alessandro Morbidelli (Observatoire de Nice, France), and Hal Levison (Southwest Research Institute, Boulder) with calculations of the solar nebula chemistry as a function of time and distance from the Sun to determine the overall chemical composition of the planets formed in the simulations. They then compared the simulated planets with the compositions of Earth and Mars. The simulated planets have chemical compositions similar to real planets, indicating that the accretion calculations are reasonable. Questions remain about the accretion of water and other highly volatile compounds, including C and N, which are essential for life.

Identifying fundamental drivers of science and developing predictive models to capture its evolution are instrumental for the design of policies that can improve the scientific enterprise-for example, through enhanced career paths for scientists, better performance evaluation for organizations hosting research, discovery of novel effective funding vehicles, and even identification of promising regions along the scientific frontier. The science of science uses large-scale data on the production of science to search for universal and domain-specific patterns. Here, we review recent developments in this transdisciplinary field.

Data science has attracted a lot of attention, promising to turn vast amounts of data into useful predictions and insights. In this article, we ask why scientists should care about data science. To answer, we discuss data science from three perspectives: statistical, computational, and human. Although each of the three is a critical component of data science, we argue that the effective combination of all three components is the essence of what data science is about.

The purpose of this paper is to present an overview of the synthesis of the scholarly literature on the definitions of the science of caring and caring science and to affirm the authors' perspective relating to the language of caring science. Caring science advances the epistemology and ontology of caring. Ideas related to caring science inquiry are presented, and the authors acknowledge the future of caring science as unitary caring science.

New paleomagnetic constraints on the lunar magnetic field evolution

NASA Astrophysics Data System (ADS)

Lepaulard, C.; Gattacceca, J.; Weiss, B. P.

2017-12-01

In the 1970s, the first paleomagnetic analyses of lunar samples from the Apollo missions allowed a glimpse of the global evolution of the Moon's magnetic field over time, with evidence for a past dynamo activity [Fuller et Cisowski, 1987]. During the last a decade, a new set of paleomagnetic studies has provided a more refined view of the evolution of the lunar dynamo activity (chronology, intensity) [Weiss et Tikoo, 2014]. The aim of this study is to further refine the knowledge of the lunar dynamo by providing new paleomagnetic data. Based on measurements of the natural remanent magnetization of the main masses of 135 Apollo samples (mass between 50 g and 5 kg) with a portable magnetometer, we have selected nine samples for laboratory analyzes. The selected Apollo samples are: 10018, 15505, 61195 (regolith breccia); 61015 (dimict breccia); 14169 (crystalline matrix breccia); 65055 (basaltic impact melt); 12005, 12021 and 15529 (basalts). Paleointensity of the lunar magnetic fields were obtained by demagnetization by alternative field and normalization with laboratory magnetizations; as well as thermal demagnetization under controlled oxygen fugacity (Thellier-Thellier method) for selected samples. Preliminary results indicate that only three samples (10018, 15505, and 15529) possess a stable high coercivity / high temperature component of magnetization. We estimated the following paleointensities: 1.5 µT for 15505, 13 µT for 15529 (both with alternating field-based methods), and 1 µT for 10018 (thermal demagnetization with the Thellier-Thellier method). The other samples provide only an upper limit for the lunar surface field. These data will be discussed in view of the age of the samples (ages from the literature, and additional dating in progress). References :Fuller, M., and S.M. Cisowski, 1987. Lunar paleomagnetism.

I will explore the similarities and differences between the process of writing science fiction and the process of 'producing' science, specifically theoretical physics. What are the ground rules for introducing unproven new ideas in science fiction, and how do they differ from the corresponding rules in physics? How predictive is science fiction? (For that matter, how predictive is theoretical physics?) I will also contrast the way in which information is presented in science fiction, as opposed to its presentation in scientific papers, and I will examine the relative importance of ideas (as opposed to the importance of the way in which these ideas are presented). Finally, I will discuss whether a background as a research scientist provides any advantage in writing science fiction.

What's science? Where's science? Science journalism in German print media.

PubMed

Summ, Annika; Volpers, Anna-Maria

2016-10-01

This article examines the current state of science coverage in German print media. It deals with the following questions: (1) how the main characteristics of science journalism can be described, (2) whether there is a difference between various scientific fields, and (3) how different definitions of science journalism lead to differing findings. Two forms of science coverage were analyzed in a standardized, two-part content analysis of German newspapers (N = 1730 and N = 1640). The results show a significant difference between a narrow and a broad definition of science journalism. In the classic understanding, science journalism is prompted by scientific events and is rather noncritical. Science coverage in a broad sense is defined by a wider range of journalistic styles, driven by non-scientific events, and with a focus on the statements of scientific experts. Furthermore, the study describes the specific role of the humanities and social sciences in German science coverage. © The Author(s) 2015.

Lanthanum doped bismuth titanate ceramic samples have been successfully synthesized by mechanochemical method showed good properties and have investigated the structure, microstructure, dielectric, Curie-Weiss behavior, thermoelectric properties, which resulted from substitution of La-ions in bismuth titanate. Plate-like shape with enhanced density is observed in the SEM micrographs. Ceramic samples exhibiting relaxor ferroelectric behavior by satisfying Curie-Weiss law. Thermoelectric studies reveal n-type semiconducting behavior of these samples. Synthesized compounds explored these desirable properties for innovative semiconductor based device applications.

Beyond Hammers and Nails: Mitigating and Verifying Greenhouse Gas Emissions

NASA Astrophysics Data System (ADS)

Gurney, Kevin Robert

2013-05-01

One of the biggest challenges to future international agreements on climate change is an independent, science-driven method of verifying reductions in greenhouse gas emissions (GHG) [Niederberger and Kimble, 2011]. The scientific community has thus far emphasized atmospheric measurements to assess changes in emissions. An alternative is direct measurement or estimation of fluxes at the source. Given the many challenges facing the approach that uses "top-down" atmospheric measurements and recent advances in "bottom-up" estimation methods, I challenge the current doctrine, which has the atmospheric measurement approach "validating" bottom-up, "good-faith" emissions estimation [Balter, 2012] or which holds that the use of bottom-up estimation is like "dieting without weighing oneself" [Nisbet and Weiss, 2010].

Paul Weiss and the genesis of canonical quantization

NASA Astrophysics Data System (ADS)

Rickles, Dean; Blum, Alexander

2015-12-01

This paper describes the life and work of a figure who, we argue, was of primary importance during the early years of field quantisation and (albeit more indirectly) quantum gravity. A student of Dirac and Born, he was interned in Canada during the second world war as an enemy alien and after his release never seemed to regain a good foothold in physics, identifying thereafter as a mathematician. He developed a general method of quantizing (linear and non-linear) field theories based on the parameters labelling an arbitrary hypersurface. This method (the `parameter formalism' often attributed to Dirac), though later discarded, was employed (and viewed at the time as an extremely important tool) by the leading figures associated with canonical quantum gravity: Dirac, Pirani and Schild, Bergmann, DeWitt, and others. We argue that he deserves wider recognition for this and other innovations.

Status of the AIAA Modeling and Simulation Format Standard

NASA Technical Reports Server (NTRS)

Jackson, E. Bruce; Hildreth, Bruce L.

2008-01-01

The current draft AIAA Standard for flight simulation models represents an on-going effort to improve the productivity of practitioners of the art of digital flight simulation (one of the original digital computer applications). This initial release provides the capability for the efficient representation and exchange of an aerodynamic model in full fidelity; the DAVE-ML format can be easily imported (with development of site-specific import tools) in an unambiguous way with automatic verification. An attractive feature of the standard is the ability to coexist with existing legacy software or tools. The draft Standard is currently limited in scope to static elements of dynamic flight simulations; however, these static elements represent the bulk of typical flight simulation mathematical models. It is already seeing application within U.S. and Australian government agencies in an effort to improve productivity and reduce model rehosting overhead. An existing tool allows import of DAVE-ML models into a popular simulation modeling and analysis tool, and other community-contributed tools and libraries can simplify the use of DAVE-ML compliant models at compile- or run-time of high-fidelity flight simulation.

Everyday science & science every day: Science-related talk & activities across settings

NASA Astrophysics Data System (ADS)

Zimmerman, Heather

To understand the development of science-related thinking, acting, and learning in middle childhood, I studied youth in schools, homes, and other neighborhood settings over a three-year period. The research goal was to analyze how multiple everyday experiences influence children's participation in science-related practices and their thinking about science and scientists. Ethnographic and interaction analysis methodologies were to study the cognition and social interactions of the children as they participated in activities with peers, family, and teachers (n=128). Interviews and participant self-documentation protocols elucidated the participants' understandings of science. An Everyday Expertise (Bell et al., 2006) theoretical framework was employed to study the development of science understandings on three analytical planes: individual learner, social groups, and societal/community resources. Findings came from a cross-case analysis of urban science learners and from two within-case analyses of girls' science-related practices as they transitioned from elementary to middle school. Results included: (1) children participated actively in science across settings---including in their homes as well as in schools, (2) children's interests in science were not always aligned to the school science content, pedagogy, or school structures for participation, yet children found ways to engage with science despite these differences through crafting multiple pathways into science, (3) urban parents were active supporters of STEM-related learning environments through brokering access to social and material resources, (4) the youth often found science in their daily activities that formal education did not make use of, and (5) children's involvement with science-related practices can be developed into design principles to reach youth in culturally relevant ways.

A lecture was presented by the author at the Democratic Opinion Forum on Health Teaching and Research, organized by Mexico's National Health Institutes Coordinating Office, at National Cardiology Institute "Ignacio Chavez", where he presented a critical review of the conventional classification of basic and applied science, as well as his personal view on health science teaching and research. According to the author, "well-conducted science" is that "generating reality-checked knowledge" and "mis-conducted science" is that "unproductive or producing 'just lies' and 'non-fundable'. To support his views, the author reviews utilitarian and pejorative definitions of science, as well as those of committed and pure science, useful and useless science, and practical and esoterical science, as synonyms of applied and basic science. He also asserts that, in Mexico, "this classification has been used in the past to justify federal funding cutbacks to basic science, allegedly because it is not targeted at solving 'national problems' or because it was not relevant to priorities set in a given six-year political administration period". Regarding health education and research, the author asserts that the current academic programs are inefficient and ineffective; his proposal to tackle these problems is to carry out a solid scientific study, conducted by a multidisciplinary team of experts, "to design the scientific researcher curricula from recruitment of intelligent young people to retirement or death". Performance assessment of researchers would not be restricted to publication of papers, since "the quality of scientific work and contribution to the development of science is not reflected by the number of published papers".

Geologic mapping of Argyre Planitia

Gorsline, Donn S.; Parker, Timothy J.

1995-01-01

This report describes the results from the geologic mapping of the central and southern Argyre basin of Mars. At the Mars Geologic Mapper's Meeting in Flagstaff during July, 1993, Dave Scott (United States Geological Survey, Mars Geologic Mapping Steering Committee Chair) recommended that all four quadrangles be combined into a single 1:1,000,000 scale map for publication. It was agreed that this would be cost-effective and that the decrease in scale would not compromise the original science goals of the mapping. Tim Parker completed mapping on the 1:500,000 scale base maps, for which all the necessary materials had already been produced, and included the work as a chapter in his dissertation, which was completed in the fall of 1994. Geologic mapping of the two southernmost quadrangles (MTM -55036 and MTM -55043; MTM=Mars Transverse Mercator) was completed as planned during the first year of work. These maps and a detailed draft of the map text were given a preliminary review by Dave Scott during summer, 1993. Geologic mapping of the remaining two quadrangles (MTM -50036 and MTM -50043) was completed by summer, 1994. Results were described at the Mars Geologic Mappers Meeting, held in Pocatello, Idaho, during July, 1994. Funds for the third and final year of the project have been transferred to the Jet Propulsion Laboratory, where Tim Parker will revise and finalize all maps and map text for publication by the United States Geological Survey at the 1:1,000,000 map scale.

Discovering indigenous science: Implications for science education

NASA Astrophysics Data System (ADS)

Snively, Gloria; Corsiglia, John

2001-01-01

Indigenous science relates to both the science knowledge of long-resident, usually oral culture peoples, as well as the science knowledge of all peoples who as participants in culture are affected by the worldview and relativist interests of their home communities. This article explores aspects of multicultural science and pedagogy and describes a rich and well-documented branch of indigenous science known to biologists and ecologists as traditional ecological knowledge (TEK). Although TEK has been generally inaccessible, educators can now use a burgeoning science-based TEK literature that documents numerous examples of time-proven, ecologically relevant, and cost effective indigenous science. Disputes regarding the universality of the standard scientific account are of critical importance for science educators because the definition of science is a de facto gatekeeping device for determining what can be included in a school science curriculum and what cannot. When Western modern science (WMS) is defined as universal it does displace revelation-based knowledge (i.e., creation science); however, it also displaces pragmatic local indigenous knowledge that does not conform with formal aspects of the standard account. Thus, in most science classrooms around the globe, Western modern science has been taught at the expense of indigenous knowledge. However, because WMS has been implicated in many of the world's ecological disasters, and because the traditional wisdom component of TEK is particularly rich in time-tested approaches that foster sustainability and environmental integrity, it is possible that the universalist gatekeeper can be seen as increasingly problematic and even counter productive. This paper describes many examples from Canada and around the world of indigenous people's contributions to science, environmental understanding, and sustainability. The authors argue the view that Western or modern science is just one of many sciences that need to be

Where civics meets science: building science for the public good through Civic Science.

PubMed

Garlick, J A; Levine, P

2017-09-01

Public understanding of science and civic engagement on science issues that impact contemporary life matter more today than ever. From the Planned Parenthood controversy, to the Flint water crisis and the fluoridation debate, societal polarization about science issues has reached dramatic levels that present significant obstacles to public discussion and problem solving. This is happening, in part, because systems built to support science do not often reward open-minded thinking, inclusive dialogue, and moral responsibility regarding science issues. As a result, public faith in science continues to erode. This review explores how the field of Civic Science can impact public work on science issues by building new understanding of the practices, influences, and cultures of science. Civic Science is defined as a discipline that considers science practice and knowledge as resources for civic engagement, democratic action, and political change. This review considers how Civic Science informs the roles that key participants-scientists, public citizens and institutions of higher education-play in our national science dialogue. Civic Science aspires to teach civic capacities, to inform the responsibilities of scientists engaged in public science issues and to inspire an open-minded, inclusive dialogue where all voices are heard and shared commitments are acknowledged. © 2016 John Wiley & Sons A/S.

Reading the interesting article Discerning selective traditions in science education by Per Sund , which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.

Secondary science teachers' attitudes toward and beliefs about science reading and science textbooks

NASA Astrophysics Data System (ADS)

Yore, Larry D.

Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.

Science Olympiad students' nature of science understandings

NASA Astrophysics Data System (ADS)

Philpot, Cindy J.

2007-12-01

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

The effects of a confidant and a peer group on the well-being of single elders.

PubMed

Gupta, V; Korte, C

1994-01-01

A study of 100 elderly people was carried out to compare the predictions of well-being derived from the confidant model with those derived from the Weiss model. The confidant model predicts that the most important feature of a person's social network for the well-being of that person is whether or not the person has a confidant. The Weiss model states that different persons are needed to fulfill the different needs of the person and in particular that a confidant is important to the need for intimacy and emotional security while a peer group of social friends is needed to fulfill sociability and identity needs. The two models were evaluated by comparing the relative influence of the confidant variable with the peer group variable on subject's well-being. Regression analysis was carried out on the well-being measure using as predictor variables the confidant variable, peer group variable, age, health, and financial status. The confidant and peer group variables were of equal importance to well-being, thus confirming the Weiss model.

Like it or not, most science depicted in feature films is in the form of science fiction. This isn't likely to change any time soon, if only because science fiction films are huge moneymakers for Hollywood. But beyond that, these films are a powerful cultural force. They reach millions as they depict scientific ideas from DNA and cloning to space science, whether correctly or incorrectly; reflect contemporary issues of science and society like climate change, nuclear power and biowarfare; inspire young people to become scientists; and provide defining images -- or stereotypes -- of scientists for the majority of people who've never met a real one. Certainly, most scientists feel that screen depictions of science and scientists are badly distorted. Many are, but not always. In this talk, based on my book Hollywood Science [1], I'll show examples of good and bad screen treatments of science, scientists, and their impact on society. I'll also discuss efforts to improve how science is treated in film and ways to use even bad movie science to convey real science.

Does science education need the history of science?

PubMed

Gooday, Graeme; Lynch, John M; Wilson, Kenneth G; Barsky, Constance K

2008-06-01

This essay argues that science education can gain from close engagement with the history of science both in the training of prospective vocational scientists and in educating the broader public about the nature of science. First it shows how historicizing science in the classroom can improve the pedagogical experience of science students and might even help them turn into more effective professional practitioners of science. Then it examines how historians of science can support the scientific education of the general public at a time when debates over "intelligent design" are raising major questions over the kind of science that ought to be available to children in their school curricula. It concludes by considering further work that might be undertaken to show how history of science could be of more general educational interest and utility, well beyond the closed academic domains in which historians of science typically operate.

Reconceptualizing the Nature of Science for Science Education

NASA Astrophysics Data System (ADS)

Dagher, Zoubeida R.; Erduran, Sibel

2016-03-01

Two fundamental questions about science are relevant for science educators: (a) What is the nature of science? and (b) what aspects of nature of science should be taught and learned? They are fundamental because they pertain to how science gets to be framed as a school subject and determines what aspects of it are worthy of inclusion in school science. This conceptual article re-examines extant notions of nature of science and proposes an expanded version of the Family Resemblance Approach (FRA), originally developed by Irzik and Nola (International handbook of research in history, philosophy and science teaching. Springer, Dordrecht, pp 999-1021, 2014) in which they view science as a cognitive-epistemic and as an institutional-social system. The conceptual basis of the expanded FRA is described and justified in this article based on a detailed account published elsewhere (Erduran and Dagher in Reconceptualizing the nature of science for science education: scientific knowledge, practices and other family categories. Springer, Dordrecht, 2014a). The expanded FRA provides a useful framework for organizing science curriculum and instruction and gives rise to generative visual tools that support the implementation of a richer understanding of and about science. The practical implications for this approach have been incorporated into analysis of curriculum policy documents, curriculum implementation resources, textbook analysis and teacher education settings.

A pragmatic conception of science: Implications for science teaching

NASA Astrophysics Data System (ADS)

Sessoms, Deidre Bates

In this dissertation, I examine various philosophical conceptions of the nature of science---its goals, methods and products---and link those views to how science is taught. While the review begins in the 1600s, the focus is primarily on logical positivism. The logical positivist view of science prevailed for much of the twentieth century and has greatly influenced how science is taught. The review section culminates with current conceptions of science from the fields of philosophy, sociology, feminist studies and radical studies of science. These various conceptions of the nature of science are linked to how science is currently taught, at the K--12 level and at the university. In particular, the logical positivist conception has influenced the teaching of science by emphasizing the products of science (factual knowledge and theories) over the processes of science (the social methods of knowledge production). As a result of viewing science as the logical positivists did, teachers primarily focus on science as unchanging factual knowledge, at the expense of examining the social and cultural aspects of scientific practices. I develop a pragmatic conception of the method of science as reflective thinking that we effectively use in our everyday lives. Linking that conception with the aims that John Dewey outlined for schools in a democratic society points the way towards certain goals and methods for teaching science. Therefore, I explore the type of science teaching that might result when viewing science as a pragmatic activity conducted in a democracy. Teaching of this sort would involve students in working together on shared problems that arise in the context of daily life. For science students at the university, this would include participating in and critiquing scientific research in active research laboratories. Implementing this view of science teaching might result in modifications in the practices and goals of science. Lastly, the experiences of a group of

Constructing a philosophy of science of cognitive science.

PubMed

Bechtel, William

2009-07-01

Philosophy of science is positioned to make distinctive contributions to cognitive science by providing perspective on its conceptual foundations and by advancing normative recommendations. The philosophy of science I embrace is naturalistic in that it is grounded in the study of actual science. Focusing on explanation, I describe the recent development of a mechanistic philosophy of science from which I draw three normative consequences for cognitive science. First, insofar as cognitive mechanisms are information-processing mechanisms, cognitive science needs an account of how the representations invoked in cognitive mechanisms carry information about contents, and I suggest that control theory offers the needed perspective on the relation of representations to contents. Second, I argue that cognitive science requires, but is still in search of, a catalog of cognitive operations that researchers can draw upon in explaining cognitive mechanisms. Last, I provide a new perspective on the relation of cognitive science to brain sciences, one which embraces both reductive research on neural components that figure in cognitive mechanisms and a concern with recomposing higher-level mechanisms from their components and situating them in their environments.

Informal science education at Science City

NASA Astrophysics Data System (ADS)

French, April Nicole

The presentation of chemistry within informal learning environments, specifically science museums and science centers is very sparse. This work examines learning in Kansas City's Science City's Astronaut Training Center in order to identify specific behaviors associated with visitors' perception of learning and their attitudes toward space and science to develop an effective chemistry exhibit. Grounded in social-constructivism and the Contextual Model of Learning, this work approaches learning in informal environments as resulting from social interactions constructed over time from interaction between visitors. Visitors to the Astronaut Training Center were surveyed both during their visit and a year after the visit to establish their perceptions of behavior within the exhibit and attitudes toward space and science. Observations of visitor behavior and a survey of the Science City staff were used to corroborate visitor responses. Eighty-six percent of visitors to Science City indicated they had learned from their experiences in the Astronaut Training Center. No correlation was found between this perception of learning and visitor's interactions with exhibit stations. Visitor attitudes were generally positive toward learning in informal settings and space science as it was presented in the exhibit. Visitors also felt positively toward using video game technology as learning tools. This opens opportunities to developing chemistry exhibits using video technology to lessen the waste stream produced by a full scale chemistry exhibit.

The Science of Science Communication and Protecting the Science Communication Environment

NASA Astrophysics Data System (ADS)

Kahan, D.

2012-12-01

Promoting public comprehension of science is only one aim of the science of science communication and is likely not the most important one for the well-being of a democratic society. Ordinary citizens form quadrillions of correct beliefs on matters that turn on complicated scientific principles they cannot even identify much less understand. The reason they fail to converge on beliefs consistent with scientific evidence on certain other consequential matters—from climate change to genetically modified foods to compusory adolescent HPV vaccination—is not the failure of scientists or science communicators to speak clearly or the inability of ordinary citizens to understand what they are saying. Rather, the source of such conflict is the proliferation of antagonistic cultural meanings. When they become attached to particular facts that admit of scientific investigation, these meanings are a kind of pollution of the science communication environment that disables the faculties ordinary citizens use to reliably absorb collective knowledge from their everyday interactions. The quality of the science communication environment is thus just as critical for enlightened self-government as the quality of the natural environment is for the physical health and well-being of a society's members. Understanding how this science communication environment works, fashioning procedures to prevent it from becoming contaminated with antagonistic meanings, and formulating effective interventions to detoxify it when protective strategies fail—those are the most critical functions science communication can perform in a democratic society.

A study of science leadership and science standards in exemplary standards-based science programs

NASA Astrophysics Data System (ADS)

Carpenter, Wendy Renae

The purpose for conducting this qualitative study was to explore best practices of exemplary standards-based science programs and instructional leadership practices in a charter high school and in a traditional high school. The focus of this study included how twelve participants aligned practices to National Science Education Standards to describe their science programs and science instructional practices. This study used a multi-site case study qualitative design. Data were obtained through a review of literature, interviews, observations, review of educational documents, and researcher's notes collected in a field log. The methodology used was a multi-site case study because of the potential, through cross analysis, for providing greater explanation of the findings in the study (Merriam, 1988). This study discovered six characteristics about the two high school's science programs that enhance the literature found in the National Science Education Standards; (a) Culture of expectations for learning-In exemplary science programs teachers are familiar with a wide range of curricula. They have the ability to examine critically and select activities to use with their students to promote the understanding of science; (b) Culture of varied experiences-In exemplary science programs students are provided different paths to learning, which help students, take in information and make sense of concepts and skills that are set forth by the standards; (c) Culture of continuous feedback-In exemplary science programs teachers and students work together to engage students in ongoing assessments of their work and that of others as prescribed in the standards; (d) Culture of Observations-In exemplary science programs students, teachers, and principals reflect on classroom instructional practices; teachers receive ongoing evaluations about their teaching and apply feedback towards improving practices as outlined in the standards; (e) Culture of continuous learning-In exemplary

I was a strong proponent of ``science diplomacy'' when I became Science and Technology Adviser to the Secretary of State in 2011. I thought I knew a lot about the subject after being engaged for four decades on international S&T policy issues and having had distinguished scientists as mentors who spent much of their time using science as a tool for building better relations between countries and working to make the world more peaceful, prosperous, and secure. I learned a lot from my three years inside the State Department, including great appreciation and respect for the real diplomats who work to defuse conflicts and avoid wars. But I also learned a lot about science diplomacy, both using science to advance diplomacy and diplomacy to advance science. My talk will focus on the five big things that I learned, and from that the one thing where I am focusing my energies to try to make a difference now that I am a private citizen again.

Is Science for Us? Black Students' and Parents' Views of Science and Science Careers.

PubMed

Archer, Louise; Dewitt, Jennifer; Osborne, Jonathan

2015-03-01

There are widespread policy concerns to improve (widen and increase) science, technology, engineering, and mathematics participation, which remains stratified by ethnicity, gender, and social class. Despite being interested in and highly valuing science, Black students tend to express limited aspirations to careers in science and remain underrepresented in post-16 science courses and careers, a pattern which is not solely explained by attainment. This paper draws on survey data from nationally representative student cohorts and longitudinal interview data collected over 4 years from 10 Black African/Caribbean students and their parents, who were tracked from age 10-14 (Y6-Y9), as part of a larger study on children's science and career aspirations. The paper uses an intersectional analysis of the qualitative data to examine why science careers are less "thinkable" for Black students. A case study is also presented of two young Black women who "bucked the trend" and aspired to science careers. The paper concludes with implications for science education policy and practice.

Can citizen science enhance public understanding of science?

Bonney, Rick; Phillips, Tina B; Ballard, Heidi L; Enck, Jody W

2016-01-01

Over the past 20 years, thousands of citizen science projects engaging millions of participants in collecting and/or processing data have sprung up around the world. Here we review documented outcomes from four categories of citizen science projects which are defined by the nature of the activities in which their participants engage - Data Collection, Data Processing, Curriculum-based, and Community Science. We find strong evidence that scientific outcomes of citizen science are well documented, particularly for Data Collection and Data Processing projects. We find limited but growing evidence that citizen science projects achieve participant gains in knowledge about science knowledge and process, increase public awareness of the diversity of scientific research, and provide deeper meaning to participants' hobbies. We also find some evidence that citizen science can contribute positively to social well-being by influencing the questions that are being addressed and by giving people a voice in local environmental decision making. While not all citizen science projects are intended to achieve a greater degree of public understanding of science, social change, or improved science -society relationships, those projects that do require effort and resources in four main categories: (1) project design, (2) outcomes measurement, (3) engagement of new audiences, and (4) new directions for research. © The Author(s) 2015.

2015-01-01

Science has always been a competitive undertaking. Despite recognition of the benefits of cooperation and team science, reduced availability of funding and jobs has made science more competitive than ever. Here we consider the benefits of competition in providing incentives to scientists and the adverse effects of competition on resource sharing, research integrity, and creativity. The history of science shows that transformative discoveries often occur in the absence of competition, which only emerges once fields are established and goals are defined. Measures to encourage collaboration and ameliorate competition in the scientific enterprise are discussed. PMID:25605760

Lagrangian statistics and flow topology in forced two-dimensional turbulence.

PubMed

Kadoch, B; Del-Castillo-Negrete, D; Bos, W J T; Schneider, K

2011-03-01

A study of the relationship between Lagrangian statistics and flow topology in fluid turbulence is presented. The topology is characterized using the Weiss criterion, which provides a conceptually simple tool to partition the flow into topologically different regions: elliptic (vortex dominated), hyperbolic (deformation dominated), and intermediate (turbulent background). The flow corresponds to forced two-dimensional Navier-Stokes turbulence in doubly periodic and circular bounded domains, the latter with no-slip boundary conditions. In the double periodic domain, the probability density function (pdf) of the Weiss field exhibits a negative skewness consistent with the fact that in periodic domains the flow is dominated by coherent vortex structures. On the other hand, in the circular domain, the elliptic and hyperbolic regions seem to be statistically similar. We follow a Lagrangian approach and obtain the statistics by tracking large ensembles of passively advected tracers. The pdfs of residence time in the topologically different regions are computed introducing the Lagrangian Weiss field, i.e., the Weiss field computed along the particles' trajectories. In elliptic and hyperbolic regions, the pdfs of the residence time have self-similar algebraic decaying tails. In contrast, in the intermediate regions the pdf has exponential decaying tails. The conditional pdfs (with respect to the flow topology) of the Lagrangian velocity exhibit Gaussian-like behavior in the periodic and in the bounded domains. In contrast to the freely decaying turbulence case, the conditional pdfs of the Lagrangian acceleration in forced turbulence show a comparable level of intermittency in both the periodic and the bounded domains. The conditional pdfs of the Lagrangian curvature are characterized, in all cases, by self-similar power-law behavior with a decay exponent of order -2.

Malory-Weis syndrome based on own experience - diagnostics and modern principles of management.

Every gastrointestinal bleeding is an immediate threat to life, requiring close supervision in a hospital setting and making it mandatory to perform verification and endoscopic intervention. In some cases of a dynamic course, in order to make up deficiencies, it is necessary to use blood and blood products. One of the causes of bleeding located proximally to the ligament of Treitz is damage to the mucous membrane and deeper layers of the gastroesophageal junction, called Mallory-Weiss syndrome. The aim of the study was retrospective analysis of a selected group of patients with symptomatic upper gastrointestinal bleeding in the course of Mallory-Weiss syndrome, identification of typical characteristics of this disease entity in the studied population as well as demonstration of the effectiveness of endoscopic treatment using argon plasma coagulation (APC). The analysis included 2120 gastroscopy results, with 111 (5.24%) examinations conducted due to symptomatic gastrointestinal bleeding. In the studied group, endoscopic diagnosis of Mallory-Weiss syndrome was made in 22 patients (1.04%). The studied disease entity was the cause of upper gastrointestinal bleeding in 19.82% of cases. Although this condition is usually characterised by a mild and self-limiting course, 59.09% of patients in the studied group required therapeutic endoscopic intervention due to active bleeding. In 54.55%, argon plasma coagulation was successfully used to control the source of bleeding. Early gastroscopy, which remains both a diagnostic and therapeutic intervention, guarantees effective control of the clinical course of Mallory-Weiss syndrome. Endoscopic argon plasma coagulation is an effective way to treat bleeding, used in endoscopic monotherapy or in combination with other procedures.

Citizen Science: Opportunities for Girls' Development of Science Identity

NASA Astrophysics Data System (ADS)

Brien, Sinead Carroll

Many students in the United States, particularly girls, have lost interest in science by the time they reach high school and do not pursue higher degrees or careers in science. Several science education researchers have found that the ways in which youth see themselves and position themselves in relation to science can influence whether they pursue science studies and careers. I suggest that participation in a citizen science program, which I define as a program in which girls interact with professional scientists and collect data that contributes to scientific research, could contribute to changing girls' perceptions of science and scientists, and promote their science identity work. I refer to science identity as self-recognition and recognition by others that one thinks scientifically and does scientific work. I examined a case study to document and analyze the relationship between girls' participation in a summer citizen science project and their development of science identity. I observed six girls between the ages of 16 and 18 during the Milkweed and Monarch Project, taking field notes on focal girls' interactions with other youth, adults, and the scientist, conducted highly-structured interviews both pre-and post- girls' program participation, and interviewed the project scientist and educator. I qualitatively analyzed field notes and interview responses for themes in girls' discussion of what it meant to think scientifically, roles they took on, and how they recognized themselves as thinking scientifically. I found that girls who saw themselves as thinking scientifically during the program seemed to demonstrate shifts in their science identity. The aspects of the citizen science program that seemed to most influence shifts in these girls' science identities were 1) the framing of the project work as "real science, 2) that it involved ecological field work, and 3) that it created a culture that valued data and scientific work. However, some of the girls only

Science teacher orientations and PCK across science topics in grade 9 earth science

NASA Astrophysics Data System (ADS)

Campbell, Todd; Melville, Wayne; Goodwin, Dawne

2017-07-01

While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade 9 earth science course. Through interviews and observations of one teacher's classroom across two sequentially taught, this research contests the notion that teachers hold a single way of conceptualising science teaching and learning. In this, we consider if multiple ontologies can provide potential explanatory power for characterising instructional enactments. In earlier work with the teacher in this study, using generic interview prompts and general discussions about science teaching and learning, we accepted the existence of a unitary STO and its promise of consistent reformed instruction in the classroom. However, upon close examination of instruction focused on different science topics, evidence was found to demonstrate the explanatory power of multiple ontologies for shaping characteristically different epistemological constructions across science topics. This research points to the need for care in generalising about teacher practice, as it reveals that a teacher's practice, and orientation, can vary, dependent on the context and science topics taught.

Single crystal growth and physical properties of BiS2-layered compound Eu3Bi2S4F4

NASA Astrophysics Data System (ADS)

Higashinaka, Ryuji; Endo, Hideaki; Kajitani, Joe; Matsuda, Tatsuma D.; Aoki, Yuji

2018-05-01

We have for the first time succeeded in growing single crystals of Eu3Bi2S4F4 by CsCl-flux method and performed magnetic property measurements. Magnetization measurements ascertained that the antiferromagnetic transition appears at TN = 2.2 K. The effective moment estimated from a Curie-Weiss (CW) fitting above 150 K is smaller than the free ion value for Eu2+, indicating that the average valence of Eu ions deviates from divalent. Weak magnetic anisotropy develops below 20 K. From CW fitting at low temperatures, we found the difference in Curie Weiss temperature between H∥ [001] and H ⊥ [ 100 ] , indicating the anisotropy of magnetic interaction between Eu ions. In the magnetization curve at 2 K (below TN), a metamagnetic anomaly appears only for the [001] direction around 0.7 T. Since this anomaly disappears above TN, this transition originates from the spin flip of Eu magnetic moments by applying magnetic field. This finding indicates that the ordered moments in the antiferromagnetic state are parallel to the [001] direction, being consistent with the anisotropic Weiss temperature, which is 20% larger for this direction.

Is Science for Us? Black Students’ and Parents’ Views of Science and Science Careers

PubMed Central

DEWITT, JENNIFER; OSBORNE, JONATHAN

2015-01-01

ABSTRACT There are widespread policy concerns to improve (widen and increase) science, technology, engineering, and mathematics participation, which remains stratified by ethnicity, gender, and social class. Despite being interested in and highly valuing science, Black students tend to express limited aspirations to careers in science and remain underrepresented in post‐16 science courses and careers, a pattern which is not solely explained by attainment. This paper draws on survey data from nationally representative student cohorts and longitudinal interview data collected over 4 years from 10 Black African/Caribbean students and their parents, who were tracked from age 10–14 (Y6–Y9), as part of a larger study on children's science and career aspirations. The paper uses an intersectional analysis of the qualitative data to examine why science careers are less “thinkable” for Black students. A case study is also presented of two young Black women who “bucked the trend” and aspired to science careers. The paper concludes with implications for science education policy and practice.

The presentation of science in everyday life: the science show

NASA Astrophysics Data System (ADS)

Watermeyer, Richard

2013-09-01

This paper constitutes a case-study of the `science show' model of public engagement employed by a company of science communicators focused on the popularization of science, technology, engineering and mathematics (STEM) subject disciplines with learner constituencies. It examines the potential of the science show to foster the interest and imagination of young learners in STEM; challenge popular pre/misconceptions of science and scientists; reveal the broadness, plurality and everyday relevance of science; and induce a more fluent and equitable science nexus between expert and non-expert or learner groups. Discussion focuses on conversations with members of a UK and university based science communication outfit who comment on the potential of the science show as a model of non-formal science education and science engagement and the necessary conditions for its success.

Science engagement and science achievement in the context of science instruction: a multilevel analysis of U.S. students and schools

NASA Astrophysics Data System (ADS)

Grabau, Larry J.; Ma, Xin

2017-05-01

Using data from the 2006 Program for International Student Assessment (PISA), we explored nine aspects of science engagement (science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities) as outcomes and predictors of science achievement. Based on results from multilevel modelling with 4456 students nested within 132 schools, we found that all aspects of science engagement were statistically significantly and positively related to science achievement, and nearly all showed medium or large effect sizes. Each aspect was positively associated with one of the (four) practices (strategies) of science teaching. Focus on applications or models was positively related to the most aspects of science engagement (science self-concept, enjoyment of science, instrumental motivation for science, general value of science, and personal value of science). Hands-on activities were positively related to additional aspects of science engagement (science self-efficacy and general interest in learning science) and also showed a positive relationship with science achievement.

2013-06-01

Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students.

Romanticism and Romantic Science: Their Contribution to Science Education

NASA Astrophysics Data System (ADS)

Hadzigeorgiou, Yannis; Schulz, Roland

2014-10-01

The unique contributions of romanticism and romantic science have been generally ignored or undervalued in history and philosophy of science studies and science education. Although more recent research in history of science has come to delineate the value of both topics for the development of modern science, their merit for the educational field has not been explored. Romanticism was not only an obvious historical period, but a particular state of mind with its own extraordinary emotional sensitivity towards nature. It is especially the latter which we hope to revisit and reclaim for science education. After discussing several key historical contributions, we describe nine characteristics of `Romantic Science' in order to focus on six ideas/possibilities that we believe hold much value for transforming current science education: (1) the emotional sensitivity toward nature, (2) the centrality of sense experience, (3) the importance of "holistic experience", (4) the importance of the notions of mystery and wonder, (5) the power of science to transform people's outlook on the natural world, and (6) the importance of the relationship between science and philosophy. It is argued that in view of a pragmatist/utilitarian conception of school science prevalent today the aforementioned ideas (especially the notion of wonder and the poetic/non-analytical mode of knowledge), can provide food for thought for both science teachers and researchers seeking to work out an aesthetic conception, one that complements current approaches such as inquiry science and conceptual change.

Microscopic origin of electric-field-induced modulation of Curie temperature in cobalt

The Curie temperature T C is one of the most fundamental physical properties of ferromagnetic materials and can be described by the Weiss molecular field theory with the exchange interaction of neighboring atoms. Here, we demonstrate the electrical control of exchange coupling in cobalt films through direct magnetization measurements. We find that the reduction in magnetization with temperature, which is caused by thermal spin wave excitation and scales with Bloch’s law, clearly depends on the applied electric field. Furthermore, we confirm that the correlation between the electric-field-induced modulation of T C and that of exchange coupling follows the Weiss molecular field theory.

Competitive science: is competition ruining science?

PubMed

Fang, Ferric C; Casadevall, Arturo

2015-04-01

Science has always been a competitive undertaking. Despite recognition of the benefits of cooperation and team science, reduced availability of funding and jobs has made science more competitive than ever. Here we consider the benefits of competition in providing incentives to scientists and the adverse effects of competition on resource sharing, research integrity, and creativity. The history of science shows that transformative discoveries often occur in the absence of competition, which only emerges once fields are established and goals are defined. Measures to encourage collaboration and ameliorate competition in the scientific enterprise are discussed. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

Young students are often natural scientists. They love to poke and prod, and they live to compare and contrast. What is the fastest animal? Where is the tallest mountain on Earth (or in the Solar System)? Where do the colors in a rainbow come from? And why do baseball players choke up on their bats? Educators work hard to harness this energy and enthusiasm in the classroom but, particularly at an early age, science enrichment - exposure outside the formal classroom - is crucial to help expand science awareness and hone science skills. Developed under a grant from NASA's Chandra X-ray Center, "STOP for Science!" is a simple but effective (and extensible) school-wide science enrichment program aimed at raising questions about science topics chosen to capture student interest. Created through the combined efforts of an astrophysicist and an elementary school principal, and strongly recommended by NASA's Earth & Space Science product review, "STOP for Science" combines aesthetic displays of science topics accompanied by level-selected questions and extensive facilitator resources to provide broad exposure to familiar, yet intriguing, science themes.

The biomedical sciences have experienced an explosion of data which promises to overwhelm many current practitioners. Without easy access to data science training resources, biomedical researchers may find themselves unable to wrangle their own datasets. In 2014, to address the challenges posed such a data onslaught, the National Institutes of Health (NIH) launched the Big Data to Knowledge (BD2K) initiative. To this end, the BD2K Training Coordinating Center (TCC; bigdatau.org) was funded to facilitate both in-person and online learning, and open up the concepts of data science to the widest possible audience. Here, we describe the activities of the BD2K TCC and its focus on the construction of the Educational Resource Discovery Index (ERuDIte), which identifies, collects, describes, and organizes online data science materials from BD2K awardees, open online courses, and videos from scientific lectures and tutorials. ERuDIte now indexes over 9,500 resources. Given the richness of online training materials and the constant evolution of biomedical data science, computational methods applying information retrieval, natural language processing, and machine learning techniques are required - in effect, using data science to inform training in data science. In so doing, the TCC seeks to democratize novel insights and discoveries brought forth via large-scale data science training. PMID:29218890

2010-10-01

The JILA Physics Frontier Center Partnerships for Informal Science Education in the Community (PISEC) provides informal afterschool inquiry-based science teaching opportunities for university participants with children typically underrepresented in science. We focus on the potential for this program to help increase children's interest in science, mathematics, and engineering and their understanding of the nature of science by validating the Children's Attitude Survey, which is based on the Colorado Learning Attitudes about Science Survey [1] and designed to measure shifts in children's attitudes about science and the nature of science. We present pre- and post-semester results for several semesters of the PISEC program, and demonstrate that, unlike most introductory physics courses in college, our after-school informal science programs support and promote positive attitudes about science.

The rapid motion of plants has intrigued scientists for centuries. Plants have neither nerves nor muscles, yet the Venus flytrap can move in a fraction of a second to capture insects. Darwin did a first systematic study on the trap closure mechanism, and called this plant ``one of the most wonderful in the world''. Several physical mechanisms have since been proposed, such as the rapid loss of turgor pressure, an irreversible acid-induced wall loosening mechanism, and tsnap-through instability, but no unanimous agreement is reached. We propose a coupled mechanical bistable mechanism that explains the rapid closure of the Venus flytrap, consistent with experimental observations. Such bistable behaviors are theoretically modeled and validated with experiments. Biomimetic flytrap robots are also fabricated according to the learnt principles. It is thus promising to design smart bio-mimetic materials and devices with snapping mechanisms as sensors, actuators, artificial muscles and biomedical devices. Zi Chen and Qiaohang Guo contributed equally.

Parents' Attitudes Towards Science and their Children's Science Achievement

NASA Astrophysics Data System (ADS)

Perera, Liyanage Devangi H.

2014-12-01

Although countries worldwide are emphasizing the importance of science education for technological development and global economic competition, comparative findings from standardized international student assessments reveal a huge gap in science scores between developed and developing countries. Certain developed economies too have made little progress in raising science achievement over the past decade. Despite school improvement being placed high on the policy agenda, the results of such actions have been poor. Therefore, there is a need to explore additional ways in which science achievement can be enhanced. This study focuses on the family and examines whether parents' attitudes towards science (how much they value science and the importance they place on it) can influence their children's science achievement. Individual- and school-level data are obtained from the Program for International Student Assessment 2006 survey for 15 Organisation for Economic Co-operation and Development (OECD) and non-OECD countries. Hierarchical linear modelling is employed to estimate the equations. The findings indicate that parents' attitudes towards science have a positive and statistically significant effect on science achievement, after controlling for other important student- and school-level variables. Moreover, students from poor backgrounds appear to benefit from more positive parental science attitudes as much as students from high socioeconomic status, such that equality of student achievement is not affected. This study recommends that schools and teachers encourage parents to play a more pro-active role in their children's science education, as well as educate parents about the importance of science and strategies that can be adopted to support their children's science learning.

The science knowledge, conceptions of the nature of science, attitudes about teaching science, and science instructional strategies of bilingual and English-only elementary teachers

NASA Astrophysics Data System (ADS)

Alegria, Adelina Victoria

The goal of this study was to explore bilingual and English-only elementary teachers' science knowledge, their conceptions of the nature of science, their attitudes about teaching science, and their self-reported science instructional skills. In this study, a bilingual teacher was defined as a teacher who provides instruction in Spanish and English in core academic subjects and has completed and/or is completing a bilingual certification program. An English-only teacher was defined as a monolingual teacher that only speaks and instructs in English. The principal questions guiding this dissertation investigation were the following: How do bilingual elementary teachers differ from English-only elementary teachers in (a) their science knowledge, (b) their conceptions of the nature of science, (c) their attitude about teaching science, and (d) their self-reported science instructional skills? This dissertation study is a component of a three-year long Eisenhower Project granted to Hueneme School District and the University of California, Santa Barbara Southcoast Science Project. While the Project will last three years (1997--2000), this dissertation study was developed to answer only a subset of questions of the entire project and data was collected in 1998. The research design for this study consisted of a self-administered questionnaire that was given to Hueneme School District elementary teachers that teach science and was developed by reviewing the relevant literature about teachers' science knowledge, their conceptions of the nature of science, their attitudes about teaching science, and the instructional strategies that support science learning. The findings showed that both the bilingual and the English-only respondents demonstrated a similar science knowledge base, which is suggested, by this researcher, to be limited. That both bilingual and English-only teacher respondents demonstrated similar positive attitudes about teaching science and both reported making

Senator Fred Harris's National Social Science Foundation proposal: Reconsidering federal science policy, natural science-social science relations, and American liberalism during the 1960s.

PubMed

Solovey, Mark

2012-03-01

During the 1960s, a growing contingent of left-leaning voices claimed that the social sciences suffered mistreatment and undue constraints within the natural science-dominated federal science establishment. According to these critics, the entrenched scientific pecking order in Washington had an unreasonable commitment to the unity of the sciences, which reinforced unacceptable inequalities between the social and the natural sciences. The most important political figure who advanced this critique, together with a substantial legislative proposal for reform, was the Oklahoma Democratic Senator Fred Harris. Yet histories of science and social science have told us surprisingly little about Harris. Moreover, existing accounts of his effort to create a National Social Science Foundation have misunderstood crucial features of this story. This essay argues that Harris's NSSF proposal developed into a robust, historically unique, and increasingly critical liberal challenge to the post-World War II federal science establishment's treatment of the social sciences as "second-class citizens."

Science and religion: implications for science educators

NASA Astrophysics Data System (ADS)

Reiss, Michael J.

2010-03-01

A religious perspective on life shapes how and what those with such a perspective learn in science; for some students a religious perspective can hinder learning in science. For such reasons Staver's article is to be welcomed as it proposes a new way of resolving the widely perceived discord between science and religion. Staver notes that Western thinking has traditionally postulated the existence and comprehensibility of a world that is external to and independent of human consciousness. This has led to a conception of truth, truth as correspondence, in which our knowledge corresponds to the facts in this external world. Staver rejects such a conception, preferring the conception of truth as coherence in which the links are between and among independent knowledge claims themselves rather than between a knowledge claim and reality. Staver then proposes constructivism as a vehicle potentially capable of resolving the tension between religion and science. My contention is that the resolution between science and religion that Staver proposes comes at too great a cost—both to science and to religion. Instead I defend a different version of constructivism where humans are seen as capable of generating models of reality that do provide richer and more meaningful understandings of reality, over time and with respect both to science and to religion. I argue that scientific knowledge is a subset of religious knowledge and explore the implications of this for science education in general and when teaching about evolution in particular.

Sociocultural influences on science and on science identities

NASA Astrophysics Data System (ADS)

Guerra, Andreia; Rezende, Flavia

2017-06-01

Angela Chapman and Allan Feldman (2016) conducted a study that aimed to exam how a group of diverse urban high school students were affected by the participation in a contextually based authentic science experience. The analysis of all data led the authors to conclude that the experience of authentic science positively influenced the science identity of students and promoted a shift in perceptions from stereotypical to more diverse views of scientists. For the purpose of this forum paper, we concentrated on the unexpected results of Hispanic students in the IAS instrument. In the authors' interpretation, Hispanic students were classified as non science identities because they do not feel recognized as a particular kind of student in that school, being possibly more marginalized than other students. We tried to expand the discussion bringing the contribution of a sociocultural approach of science construction and of science identity to enrich some of the issues involved. Our concise analysis does not allow conclusions about the Hispanic students' results, but we believe it helped to understand sociocultural problems involved in their science identity and to reveal the inequality in science production as one of these problems.

New concepts of science and medicine in science and technology studies and their relevance to science education.

PubMed

Wang, Hsiu-Yun; Stocker, Joel F; Fu, Daiwie

2012-02-01

Science education often adopts a narrow view of science that assumes the lay public is ignorant, which seemingly justifies a science education limited to a promotional narrative of progress in the form of scientific knowledge void of meaningful social context. We propose that to prepare students as future concerned citizens of a technoscientific society, science education should be informed by science, technology, and society (STS) perspectives. An STS-informed science education, in our view, will include the following curricular elements: science controversy education, gender issues, historical perspective, and a move away from a Eurocentric view by looking into the distinctive patterns of other regional (in this case of Taiwan, East Asian) approaches to science, technology, and medicine. This article outlines the significance of some major STS studies as a means of illustrating the ways in which STS perspectives can, if incorporated into science education, enhance our understanding of science and technology and their relationships with society.

Teaching Science with the Social Studies of Science for Equity

NASA Astrophysics Data System (ADS)

Lederman, Muriel

Integrating the social studies of science into science education would make explicit the cultures of science, which have been revealed by historians, philosophers, sociologists, and feminist science scholars. These cultures include the institutions of science, the interaction of science and the society in which it is practiced, and the internal culture of science. This pedagogy may be a route to increasing equity in science, by giving women and members of other under-represented groups an appreciation of the factors causing their alienation from the enterprise and the tools to change science for social justice. In this article, I present the theoretical basis of this position, along with the implementation strategies and preliminary assessment for a sophomore level biology course based on this perspective.

The effects of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science

NASA Astrophysics Data System (ADS)

Logerwell, Mollianne G.

The purpose of this study was to investigate the impact of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science. Master's degree students enrolled in the elementary Fairfax Partnership Schools (FPS, n = 21) cohort served as the treatment group, while those enrolled in the Loudoun Partnership Schools (LPS, n = 15) and Professional Development Schools (PDS, n = 24) cohorts at George Mason University served as the control groups. The treatment group planned for and taught a two-week inquiry- and problem-based summer science camp as part of their science methods course, while the control groups did not. The Science Teaching Efficacy Belief Instrument (STEBI), a science content assessment, a personal data questionnaire, and a modified version of the Views of Nature of Science Questionnaire (VNOS-C) were administered to the participants at the beginning and end of their science methods course. Analyses revealed significant increases for the FPS group in general science teaching efficacy, personal science teaching efficacy, science teaching outcome expectancy, general science knowledge, biology content knowledge, chemistry content knowledge, and understanding of NOS; the LPS group in general science teaching efficacy, personal science teaching efficacy, chemistry content knowledge, and understanding of NOS; and, the PDS group in general science teaching efficacy, personal science teaching efficacy, and chemistry content knowledge. Additionally, the FPS group had significantly higher general science teaching efficacy than both control groups, personal science teaching efficacy than the PDS group, and understanding of NOS than the LPS group. Overall, the findings indicate that course length is not as important for developing preservice teachers' teaching efficacy and understanding of content as having connected, authentic field-based teaching experiences

When Nature of Science Meets Marxism: Aspects of Nature of Science Taught by Chinese Science Teacher Educators to Prospective Science Teachers

NASA Astrophysics Data System (ADS)

Wan, Zhi Hong; Wong, Siu Ling; Zhan, Ying

2013-05-01

Nature of science (NOS) is beginning to find its place in the science education in China. In a study which investigated Chinese science teacher educators' conceptions of teaching NOS to prospective science teachers through semi-structured interviews, five key dimensions emerged from the data. This paper focuses on the dimension, NOS content to be taught to prospective science teachers. Among a total of twenty NOS elements considered by the Chinese science teacher educators to be important ideas to be taught, five were suggested by no less than a half of the educators. They are (1) empirical basis of scientific investigation, (2) logics in scientific investigation, (3) general process of scientific investigation, (4) progressive nature of scientific knowledge, and (5) realist views of mind and natural world. This paper discusses the influence of Marxism, a special socio-cultural factor in China, on Chinese science teacher educators' conceptions of NOS content to be taught to prospective science teachers. We argue the importance of considering ideological traditions (mainly those in general philosophy and religion) when interpreting views of NOS or its content to be taught in different countries and regions and understanding students' conceptual ecology of learning NOS.

Earlier studies [Mallow, J. V. (1994). Gender-related science anxiety: A first binational study. Journal of Science Education and Technology 3: 227-238; Udo, M. K., Ramsey, G. P., Reynolds-Alpert, S., and Mallow, J. V. (2001). Does physics teaching affect gender-based science anxiety? Journal of Science Education and Technology 10: 237-247] of science anxiety in various student cohorts suggested that nonscience majors were highly science anxious (SA), regardless of what science courses they were taking. In this study, we investigated science anxiety in a cohort consisting mostly of nonscience majors taking general education science courses. Regression analysis shows that the leading predictors of science anxiety are (i) nonscience anxiety and (ii) gender, as they were for different cohorts in the earlier studies. We confirm earlier findings that females are more SA than males. Chi-square analysis of acute science anxiety shows an amplification of these differences. We found statistically significant levels of science anxiety in humanities and social science students of both genders, and gender differences in science anxiety, despite the fact that the students were all enrolled in general education science courses specifically designed for nonscience majors. We found acute levels of anxiety in several groups, especially education, nursing, and business majors. We describe specific interventions to alleviate science anxiety.

Exploring Girls' Science Affinities Through an Informal Science Education Program

NASA Astrophysics Data System (ADS)

Todd, Brandy; Zvoch, Keith

2017-10-01

This study examines science interests, efficacy, attitudes, and identity—referred to as affinities, in the context of an informal science outreach program for girls. A mixed methods design was used to explore girls' science affinities before, during, and after participation in a cohort-based summer science camp. Multivariate analysis of survey data revealed that girls' science affinities varied as a function of the joint relationship between family background and number of years in the program, with girls from more affluent families predicted to increase affinities over time and girls from lower income families to experience initial gains in affinities that diminish over time. Qualitative examination of girls' perspectives on gender and science efficacy, attitudes toward science, and elements of science identities revealed a complex interplay of gendered stereotypes of science and girls' personal desires to prove themselves knowledgeable and competent scientists. Implications for the best practice in fostering science engagement and identities in middle school-aged girls are discussed.

Literacy, science, and science education

NASA Astrophysics Data System (ADS)

McVittie, Janet Elizabeth

In examining the connections between literacy, science and science education, I laid out a number of questions. For example, what sorts of literate tools might facilitate writing to learn, and do children who are just becoming literate use these tools? I then examined the writing of children in science class in an attempt to determine if their writing can indeed facilitate their learning. The results of this research could help teachers make decisions about the use of writing in the learning of science. The kinds of literate tools I identified as being potentially helpful were transitionals---those words or grammatical devices which demonstrate how ideas are connected. Also, I suggested that data tables, sentences and paragraphs were also useful for students to learn. I found that grade 5/6 students used a wide range of literate tools, but that they were much more competent with those tools which were both oral and literate than those which could only be used for writing (punctuation, sentences, paragraphs, and data tables). When I attempted to determine if the children used their writing to learn, I found very little evidence that this was certainly so. However, there was some evidence that paragraphs had the potential to create a "dialogue" between student writing and thinking, so the students could make more explicit connections between science ideas. Lastly, I noticed certain gender difference in the classroom. Because of this, I contrasted the writing of the girls with the writing of the boys. I learned the girls were generally much more capable writers than the boys. More interesting, however, was that the girls generally attempted to explain their science concepts in different ways than did the boys. The girls were more likely to rely on their own reasoning, whereas the boys were more likely to persist in using culturally created science explanations. The research findings have important implications for analyzing students' learning and for finding ways to

The Nature of Science and Science Education: A Bibliography

NASA Astrophysics Data System (ADS)

Bell, Randy; Abd-El-Khalick, Fouad; Lederman, Norman G.; Mccomas, William F.; Matthews, Michael R.

Research on the nature of science and science education enjoys a long history, with its origins in Ernst Mach's work in the late nineteenth century and John Dewey's at the beginning of the twentieth century. As early as 1909 the Central Association for Science and Mathematics Teachers published an article - A Consideration of the Principles that Should Determine the Courses in Biology in Secondary Schools - in School Science and Mathematics that reflected foundational concerns about science and how school curricula should be informed by them. Since then a large body of literature has developed related to the teaching and learning about nature of science - see, for example, the Lederman (1992)and Meichtry (1993) reviews cited below. As well there has been intense philosophical, historical and philosophical debate about the nature of science itself, culminating in the much-publicised Science Wars of recent time. Thereferences listed here primarily focus on the empirical research related to the nature of science as an educational goal; along with a few influential philosophical works by such authors as Kuhn, Popper, Laudan, Lakatos, and others. While not exhaustive, the list should prove useful to educators, and scholars in other fields, interested in the nature of science and how its understanding can be realised as a goal of science instruction. The authors welcome correspondence regarding omissions from the list, and on-going additions that can be made to it.

2014-12-01

The science of rare natural hazards provides us an opportunity that our ancestors lacked: the chance to learn what hazards we could face, and how reliable any particular precursor may or may not be. Connecting hazard science to societal learning is far too complex a challenge for our intuitions to be of much use. Instead, we need to use evidence - the science of science communication - to identify what actually works. As practitioners, we first worked with NGOs and local governments in coastal Sumatran communities to develop tsunami evacuation guidance that is consistent with the science of tsunamis and suitable for the communities that face the threat. This work identified important practical questions that social science can address: how do people decide whether to evacuate, and how do hazard knowledge and experience influence this? How acceptable are false alarms? What modes of communicating tsunami science and its uncertainties may lead to greater willingness to evacuate, and greater acceptance of false alarms? Which parts of the vast body of research on communication, risk perception, and decision-making might be significant in these contexts? We are beginning research at the household level that will address these questions and feed back into our continuing science-communication practice.

Investigating Science Discourse in a High School Science Classroom

NASA Astrophysics Data System (ADS)

Swanson, Lauren Honeycutt

Science classrooms in the United States have become more diverse with respect to the variety of languages spoken by students. This qualitative study used ethnographic methods to investigate the discourse and practices of two ninth grade science classrooms. Approximately 44% of students included in the study were designated as English learners. The present work focused on addressing the following questions: 1) In what ways is science discourse taken up and used by students and their teacher? 2) Are there differences in how science discourse is used by students depending on their English language proficiency? Data collection consisted of interviewing the science teacher and the students, filming whole class and small group discussions during two lesson sequences, and collecting lesson plans, curricular materials, and student work. These data were analyzed qualitatively. Findings indicated that the teacher characterized science discourse along three dimensions: 1) the use of evidence-based explanations; 2) the practice of sharing one's science understandings publically; and 3) the importance of using precise language, including both specialized (i.e., science specific) and non-specialized academic words. Analysis of student participation during in-class activities highlighted how students progressed in each of these science discourse skills. However, this analysis also revealed that English learners were less likely to participate in whole class discussions: Though these students participated in small group discussions, they rarely volunteered to share individual or collective ideas with the class. Overall, students were more adept at utilizing science discourse during class discussions than in written assignments. Analysis of students' written work highlighted difficulties that were not visible during classroom interactions. One potential explanation is the increased amount of scaffolding the teacher provided during class discussions as compared to written

Response to this fact sheet demonstrated a need to further expand this document. Thus, this expanded version builds on the April 2004 position paper, What is Science? This paper clarifies what is science, the scientific method, a scientific hypothesis, a scientific theory, the importance of science, and what is not science.

The role of science self-efficacy, science career efficacy, science career interest, and intentions to enroll in nonrequired science courses in the future selection of science-related careers for high school students

Underrepresentation of non-Asian minority groups and women in science and math related professions has been an area of concern for many years. The purpose of this study was to examine the role of career selection variables for African-American and European-American students on future aspirations of pursuing a science-related career. Other examined variables included gender, academic track and socioeconomic status. A survey was completed by 368 high school students in rural settings in the Southeastern portion of the United States. Gender, race, tracking, and socioeconomic differences in career selection variables and future aspirations of pursuing a science-related career were explored using a 2 x 2 x 2 x 2 MANOVA. Multiple regression was used to examine the predictiveness of career selection variables relative to future career aspirations of pursuing a science-related career. Results indicated that African-Americans reported higher total science career interest, and higher science career efficacy. European-American students reported higher levels of science self-efficacy relative to making a B or better in science courses and solving science-related problems. Also, European-Americans reported higher levels of interest in science-related tasks, a subscale on the science career interest variable. When the effect of gender was examined across the total sample, no differences were found. However, when gender was examined by race, European-American females reported higher levels of science career interest than European-American males. Students from high academic tracking groups reported greater efficacy for completing science-related technical skills. Science career interest was predictive of future career selection for this sample.

Cognitive Science and Science Education.

The premise behind the cognitive approach to teaching is that understanding results when new learning is integrated with existing knowledge. But the goal of science instruction is to replace existing ideas with new theories. Current research in science education seeks to resolve these conflicting instructional approaches. (Author/VM)

Elucidating elementary science teachers' conceptions of the nature of science: A view to beliefs about both science and teaching

NASA Astrophysics Data System (ADS)

Keske, Kristina Palmer

The purpose of this interpretive case study was to elucidate the conceptions of the nature of science held by seven elementary science teachers. The constructivist paradigm provided the philosophical and methodological foundation for the study. Interviews were employed to collect data from the participants about their formal and informal experiences with science. In addition, the participants contributed their perspectives on four aspects of the nature of science: what is science; who is a scientist; what are the methods of science; and how is scientific knowledge constructed. Data analysis not only revealed these teachers' views of science, but also provided insights into how they viewed science teaching. Four themes emerged from the data. The first theme developed around the participants' portrayals of the content of science, with participant views falling on a continuum of limited to universal application of science as procedure. The second theme dealt with the participants' views of the absolute nature of scientific knowledge. Participants' perceptions of the tentative nature of science teaching provided the basis for the third theme concerning the need for absolutes in practice. The fourth theme drew parallels between participants' views of science and science teaching, with two participants demonstrating a consistency in beliefs about knowledge construction across contexts. This study revealed both personal and contextual factors which impacted how the participants saw science and science teaching. Many of the participants' memories of formal science revolved around the memorization of content and were viewed negatively. All the participants had limited formal training in science. Of the seven participants, only two had chosen to be science teachers at the beginning of their careers. The participants' limited formal experiences with science provided little time for exploration into historical, philosophical, and sociological studies of science, a necessary

Learning Science, Learning about Science, Doing Science: Different goals demand different learning methods

NASA Astrophysics Data System (ADS)

Hodson, Derek

2014-10-01

This opinion piece paper urges teachers and teacher educators to draw careful distinctions among four basic learning goals: learning science, learning about science, doing science and learning to address socio-scientific issues. In elaboration, the author urges that careful attention is paid to the selection of teaching/learning methods that recognize key differences in learning goals and criticizes the common assertion that 'current wisdom advocates that students best learn science through an inquiry-oriented teaching approach' on the grounds that conflating the distinction between learning by inquiry and engaging in scientific inquiry is unhelpful in selecting appropriate teaching/learning approaches.

Mars: A Freshmen Year Seminar of Science and Science-fiction

NASA Astrophysics Data System (ADS)

Svec, Michael; Moffett, D. A.; Winiski, M.

2013-06-01

"Mars: On the shoulder of giants" is a freshmen year seminar developed collaboratively between the physics, education, and center for teaching and learning. This course focuses on how scientific knowledge is developed through the lens of our changing view of Mars throughout history. Analyses of current studies of Mars are juxtaposed against historical understanding and perceptions of the planet found in scientific and popular literature of the day, as well as the movies. Kim Stanley Robinson’s "Red Mars" provides a unifying story throughout the course complimented by Fredrick Taylor’s "The Scientific Exploration of Mars" and Hartmann’s "A Traveler’s Guide to Mars." Based on the three-years of experience, the authors advocate the use of the speculative science-fiction novel and argue for its use in high school and undergraduate courses including those for science majors. Many of the students who selected this seminar went on to major in science and in subsequent interviews discussed the influence of science fiction on their decision to major in science. Science fiction provided story, science, and speculation that became a rich medium for critical-thinking skills and critical literacy. Student reflections indicated that science fiction served as a reminder of why they study science, a source for imagination, and exploration of science as a human endeavor. Based on this experience, we propose five elements for selecting science-fiction for inclusion in science classes: 1) Provides a deep description of the science content or technologies, 2) Describes science and technologies are plausible or accurate to the time period, 3) Contains a novum or plausible innovation that plays a key element in the speculation, 4) Exploration of the impact on society or humanity, and, 5) Shows science and technology as human endeavors.

The Science Identity and Entering a Science Occupation*

Stets, Jan E.; Brenner, Philip S.; Burke, Peter J.; Serpe, Richard T.

2016-01-01

The initiative to increase the number of students in STEM disciplines and train them for a science-related job is a current national focus. Using longitudinal panel data from a national study that followed underrepresented college students in STEM fields, we investigate the neglected role that social psychological processes play in influencing science activity among the young. We study the impact of identity processes related to being a science student on entering a science occupation. More broadly, we examine whether an identity formulated in one institutional setting (education) has effects that persist to another institutional setting (the economy). We find that the science identity positively impacts the likelihood of entering a science occupation. It also serves as a mediator for other factors that are related to educational success. This provides insight into how an identity can guide behavior to move persons into structural positions across institutional domains. PMID:28364837

Science Outside the Lab: Helping Graduate Students in Science and Engineering Understand the Complexities of Science Policy.

Bernstein, Michael J; Reifschneider, Kiera; Bennett, Ira; Wetmore, Jameson M

2017-06-01

Helping scientists and engineers challenge received assumptions about how science, engineering, and society relate is a critical cornerstone for macroethics education. Scientific and engineering research are frequently framed as first steps of a value-free linear model that inexorably leads to societal benefit. Social studies of science and assessments of scientific and engineering research speak to the need for a more critical approach to the noble intentions underlying these assumptions. "Science Outside the Lab" is a program designed to help early-career scientists and engineers understand the complexities of science and engineering policy. Assessment of the program entailed a pre-, post-, and 1 year follow up survey to gauge student perspectives on relationships between science and society, as well as a pre-post concept map exercise to elicit student conceptualizations of science policy. Students leave Science Outside the Lab with greater humility about the role of scientific expertise in science and engineering policy; greater skepticism toward linear notions of scientific advances benefiting society; a deeper, more nuanced understanding of the actors involved in shaping science policy; and a continued appreciation of the contributions of science and engineering to society. The study presents an efficacious program that helps scientists and engineers make inroads into macroethical debates, reframe the ways in which they think about values of science and engineering in society, and more thoughtfully engage with critical mediators of science and society relationships: policy makers and policy processes.

As states begin to review their standards, some adopt or adapt the NGSS and others write their own, many basing these on the Framework for K-12 Science Education. Both the NGSS and the Frameworks have an increased emphasis on Earth Science but many high school teachers are being asked to teach these standards in traditional Biology, Chemistry and Physics courses. At the Earth Educators Rendezvous, teachers, scientists, and science education researchers worked together to find the interconnections between the sciences using the NGSS and identified ways to reference the role of Earth Sciences in the other sciences during lectures, activities and laboratory assignments. Weaving Earth and Space sciences into the other curricular areas, the teams developed relevant problems for students to solve by focusing on using current issues, media stories, and community issues. These and other lessons and units of study will be presented along with other resources used by teachers to ensure students are gaining exposure and a deeper understanding of Earth and Space Science concepts.

Science Anxiety, Science Attitudes, and Constructivism: A Binational Study

Bryant, Fred B.; Kastrup, Helge; Udo, Maria; Hislop, Nelda; Shefner, Rachel; Mallow, Jeffry

2013-08-01

Students' attitudes and anxieties about science were measured by responses to two self-report questionnaires. The cohorts were Danish and American students at the upper secondary- and university-levels. Relationships between and among science attitudes, science anxiety, gender, and nationality were examined. Particular attention was paid to constructivist attitudes about science. These fell into at least three broad conceptual categories: Negativity of Science Toward the Individual, Subjective Construction of Knowledge, and Inherent Bias Against Women. Multigroup confirmatory factor analyses revealed that these dimensions of constructivist attitudes were equally applicable and had the same meaning in both cultures. Gender differences in mean levels of constructivist attitudes were found; these varied across the two cultures. Constructivist beliefs were associated with science anxiety, but in different ways for females and males, and for Danes and Americans. In agreement with earlier studies, females in both the US and Danish cohorts were significantly more science anxious than males, and the gender differences for the Americans were larger than those for the Danes. Findings are discussed in terms of their implications for reducing science anxiety by changing constructivist beliefs.

Gender roles and science beliefs and their relationship to science interest

NASA Astrophysics Data System (ADS)

Paolucci, Judith Jean

This study investigated adolescents' views about the nature of science (NOS) and conceptions of their gender identities, and revealed whether these conceptions and views are related to their science interest. Participants were 566 high school students enrolled in chemistry courses at three high schools in a New England state. A questionnaire was used to assess participants' science interest, gender role perceptions, and views about science, as well as to provide background and math and science achievement data. The study found that while student scores of NOS understanding did not differ by gender, some significant differences were noted on the student responses to statements about science. Students with higher-than-average science interest scores responded to these statements differently than students with lower science interest scores; their responses tended to more closely match statements about NOS taken from current reform documents. The study also found that math and science achievement, masculinity scores, and NOS scores accounted for a greater variance of science interest for girls than for boys, though all three also contributed significantly and positively to the regression equation for boys. These predictor variables predicted membership to the lower or higher science interest groups, but could not predict students' career aspiration groups. Thus, other mediating factors not considered in this study may translate high science interest to science career aspiration. The results of this study coed prior research, which found that science and math achievement and masculinity are positively and significantly related to science interest for boy boys and girls. Moreover, the study found that achievement in math and science courses is a greater predictor of science interest for girls than for boys. The results of this study provide a rationale for incorporating the nature of science into the science curriculum. Moreover, since the science interest of boys was

Can participation in a school science fair improve middle school students' attitudes toward science and interest in science careers?

NASA Astrophysics Data System (ADS)

Finnerty, Valerie

The purpose of this study was to investigate whether participation in a school-based science fair affects middle school students' attitudes toward science and interest in science and engineering careers. A quasi-experimental design was used to compare students' pre- and posttest attitudes toward and interest in science. Forty-eight of the 258 participants completed a school-based science fair during the study. In addition, twelve middle school science teachers completed an online survey. Both the Survey of Science Attitudes and Interest I and II (SSAI-I and II) measured students' attitudes toward and interest in science and science and mathematics self-efficacy, asked about classroom inquiry experiences and gathered demographic information. An online survey gathered qualitative data about science teachers' perceptions of school science fairs. The results showed no significant interactions among completion of a science fair project and attitudes toward and interest in science, science and mathematics self-efficacy or gender. There were significant differences at both pre- and posttest in attitudes between the students who did and did not complete a science fair project. All participating teachers believed that participation in science fairs could have a positive effect on students' attitudes and interest, but cited lack of time as a major impediment. There was significant interaction between level of classroom inquiry and attitudes and interest in science; students who reported more experiences had higher scores on these measures. Classroom inquiry also interacted with the effects of a science fair and participants' pre- and posttest attitude scores. Finally, the amount and source of assistance on a science fair project had a significant impact on students' posttest measures. Major limitations which affect the generalization of these findings include the timing of the administration of the pretest, the number of participants in the experimental group and differences

Science as theater, theater as science

NASA Astrophysics Data System (ADS)

Lustig, Harry

2002-04-01

Beginning with Bertold Brecht's "Galileo" in 1942 and Friedrich Dürrenmatt's "The Physicists" in 1962, physics and other sciences have served a number of dramatists as backdrops for the exposition of existential problems, as well as the provision of entertainment. Michael Frayn's 1998 play "Copenhagen" broke new ground by giving a central role to the presentation of scientific substance and ideas and to the examination of recent controversial and emotionally charged events in the history of science and of the "real world". A rash of "science plays" erupted. How should we physicists react to this development? Surely, it can be argued, any exposure of science to the public is better than none and will help break down the barriers between the "two cultures". But what if the science or the scientists are badly misrepresented or the play is a weapon to strip science of its legitimacy and its claims to reality and truth? After reviewing a half dozen of the new plays, I conclude that "Copenhagen", though flawed, is not only the best of show, but a positive, even admirable endeavor. The contributions of Bohr, Heisenberg, Born, Schrödinger, and other scientists and their interactions in the golden years of the creation of quantum mechanics are accurately and thrillingly rendered. There may be no better non-technical exposition of complementarity and the uncertainty principle than the one that Frayn puts into the mouths of Bohr and Heisenberg. The treatment of the history of the atomic bomb and Heisenberg's role in Germany's failure to achieve a bomb is another matter. Frayn can also be criticized for applying uncertainly and complementarity to the macroscopic world and, in particular, to human interactions, thereby giving some aid and comfort to the post-modernists. These reservations aside, Copenhagen is a beautiful contribution to the appreciation of science.

Preservice Elementary Teachers' Science Self-Efficacy Beliefs and Science Content Knowledge

NASA Astrophysics Data System (ADS)

Menon, Deepika; Sadler, Troy D.

2016-10-01

Self-efficacy beliefs that relate to teachers' motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers' science self-efficacy beliefs. However, there are few studies examining the relationship between science self-efficacy beliefs and science content knowledge. The purpose of this mixed methods study is to investigate changes in preservice teachers' science self-efficacy beliefs and science content knowledge and the relationship between the two variables as they co-evolve in a specialized science content course. Results from pre- and post-course administrations of the Science Teaching Efficacy Belief Instrument-B (Bleicher, 2004) and a physical science concept test along with semi-structured interviews, classroom observations and artifacts served as data sources for the study. The 18 participants belonged to three groups representing low, medium and high initial levels of self-efficacy beliefs. A repeated measures multivariate analysis of variance design was used to test the significance of differences between the pre- and post-surveys across time. Results indicated statistically significant gains in participants' science self-efficacy beliefs and science conceptual understandings. Additionally, a positive moderate relationship between gains in science conceptual understandings and gains in personal science teaching efficacy beliefs was found. Qualitative analysis of the participants' responses indicated positive shifts in their science teacher self-image and they credited their experiences in the course as sources of new levels of confidence to teach science. The study includes implications for preservice teacher education programs, science teacher education, and research.

We present a novel approach for creating science-ready catalogs through a software infrastructure developed for the Dark Energy Survey (DES). We integrate the data products released by the DES Data Management and additional products created by the DES collaboration in an environment known as DES Science Portal. Each step involved in the creation of a science-ready catalog is recorded in a relational database and can be recovered at any time. We describe how the DES Science Portal automates the creation and characterization of lightweight catalogs for DES Year 1 Annual Release, and show its flexibility in creating multiple catalogs withmore » different inputs and configurations. Finally, we discuss the advantages of this infrastructure for large surveys such as DES and the Large Synoptic Survey Telescope. The capability of creating science-ready catalogs efficiently and with full control of the inputs and configurations used is an important asset for supporting science analysis using data from large astronomical surveys.« less

Science Enterprises are problems that students genuinely want to solve, questions that students genuinely want to answer, that naturally entail reading, writing, investigation, and discussion. Engaging students in personally-relevant science enterprises provides both a diagnostic opportunity and a context for providing students the comprehensible input they need. We can differentiate instruction by creating science enterprise zones that are set up for the incremental increase in challenge for the students. Comprehensible input makes reachable, those just-out-of-reach concepts in the mix of the familiar and the new.

Language Acquisition is an informal process that occurs in the midst of

Science access, career choices, achievement, and motivation: Perceptions of female science olympians

NASA Astrophysics Data System (ADS)

Price, Kelly Rae

Women remain under-represented in science career fields and this is especially evident in the physical sciences. Female students maintain equal science interest and achievement to male students in elementary school but by middle and high school they fall behind their male peers. Reasons cited for girls' declining interest in science include battling traditional gender stereotypes, lack of encouragement, and lack of female role models. Four main science concerns related to girls/women as indicated by research literature were science access, career choices, achievement, and motivation. In Georgia, some girls have made a break from the research trends by demonstrating their fervor for science through participation in the academic activity, Science Olympiad. The purpose of this study was to examine the science perceptions of girls who demonstrated science success by their participation in Science Olympiad. Utilizing phenomenological and feminist perspectives, the qualitative research method of focus group interviewing was used to address the research questions comprising the four science concerns of female science access, career choices, achievement, and motivation. The study participants were all girls/women who participated in Science Olympiad. A total of five focus groups were studied. One of the focus groups had current college undergraduates, former Science Olympians, in it while the others were composed of high school girls. Through the description of their science experiences, the participants shared their perceptions of the four science concerns. When addressing these science concerns, the participants revealed four factors that had most affected their science perceptions: the importance of support, science needs Serious Fun, teachers matter, and the bonuses of extracurricular involvement. In their experiences, the participants found success in science because they had teachers, parents, and peers who supported their academic interests, including science, and

Understanding high school students' science internship: At the intersection of secondary school science and university science

NASA Astrophysics Data System (ADS)

Hsu, Pei-Ling

In this dissertation I explore the nature of an internship for high school students in a university science laboratory and the issues that arise from it. The investigation of science internships is relatively new to science education; therefore, this exploration is urgently needed. Twenty-one participants were involved in the internship experience, including 13 students, one teacher, two research scientists, and five technicians. Data sources include observations, field notes, and videotapes. Drawing on four coherent and complementary research tools---cultural-historical activity theory, discourse analysis, conversation analysis, and phenomenography, I articulate a variety of phenomena from multiple perspectives. The phenomena identified in the dissertation include (a) the discursive resources deployed by a teacher for interesting and inviting students to participate in science; (b) the discursive resources high school students used for articulating their interests in science-related careers; (c) the natural pedagogical conversations for accomplishing the work of teaching and learning during the internship; (d) the theoretical concepts mobilized for describing the unfolding of science expertise in the internship; (e) participants' ways of experiencing the science internship; and (f) students' understandings of scientific practice after participating in the internship. The study identifies many useful resources for understanding the nature of the science internship and provides a foundation for future research. The findings reported here will also serve others as a springboard for establishing partnerships between high schools and science communities and improving teaching and learning in science education.

Abstract Citizen science involves a range of practices involving public participation in scientific knowledge production, but outcomes evaluation is complicated by the diversity of the goals and forms of citizen science. Publications and citations are not adequate metrics to describe citizen-science productivity. We address this gap by contributing a science products inventory (SPI) tool, iteratively developed through an expert panel and case studies, intended to support general-purpose planning and evaluation of citizen-science projects with respect to science productivity. The SPI includes a collection of items for tracking the production of science outputs and data practices, which are described and illustrated with examples. Several opportunities for further development of the initial inventory are highlighted, as well as potential for using the inventory as a tool to guide project management, funding, and research on citizen science.

Science as religion: when science becomes (too) irrational.

PubMed

Muzur, Amir; Rinčić, Iva

2017-04-01

Science is expected to be objective: however, since practiced and produced by humans, it has to reflect human flows - prejudices, stubbornness, malice, and the tendency to be misused. No wonder an excellent scientist like John Eccles proclaimed science to be among the most personal activities he had known. By analysing a few examples from the history of science (in particular the intellectual development of Van Rensselaer Potter, the American onco-biochemist and bioethics pioneer), as well as the current trend of the evidence-based approach, the present paper will try to demonstrate that denying, distrusting, and opposing science for the sake of religion, as seen so many times in human history, has significant similarities to the overestimation of science we more often encounter in our times.

Polar Science Weekend: A University / Science Center Collaboration

NASA Astrophysics Data System (ADS)

Stern, H. L.; Moritz, R. E.; Lettvin, E.; Schatz, D.; Russell, L.

2008-12-01

Polar Science Weekend (PSW) is a four-day event featuring hands-on activities, live demonstrations, and a variety of exhibits about the polar regions and current polar research, presented by scientists from the University of Washington's Polar Science Center, and held at Seattle's Pacific Science Center. PSW was conceived and organized jointly by the Polar Science Center and Pacific Science Center, which is Washington State's most well-attended museum. The first PSW in March 2006 drew over 5000 visitors, and subsequent PSWs in 2007 and 2008 have both surpassed that figure. The success of this university / science center partnership has made PSW an annual event, and has served as a model for Pacific Science Center's Portal to the Public program, in which partnerships with other scientific institutions have been built. Researchers at the Polar Science Center (PSC) study the physical processes controlling high-latitude oceans, atmosphere, sea ice, and ice sheets, and are involved in numerous IPY projects. PSC scientists also engage in many outreach efforts such as classroom visits and public lectures, but PSW stands out as the highlight of the year. The partnership with Pacific Science Center brings access to facilities, publicity, and a large audience that would not otherwise be readily available to PSC. Pacific Science Center, constructed for the 1962 World's Fair in Seattle, serves more than one million visitors per year. Pacific Science Center's mission is to inspire a lifelong interest in science, math and technology by engaging diverse communities through interactive and innovative exhibits and programs. PSW helps to advance this mission by bringing students, teachers, and families face-to-face with scientists who work in some of the most remote and challenging places on earth, to learn first-hand about polar research in a fun and informal setting. This is made possible only by the partnership with PSC. In this talk we will present descriptions and photos of PSW

Delocalized and localized states of eg electrons in half-doped manganites.

PubMed

Winkler, E L; Tovar, M; Causa, M T

2013-07-24

We have studied the magnetic behaviour of half-doped manganite Y0.5Ca0.5MnO3 in an extended range of temperatures by means of magnetic susceptibility, χ(T), and electron spin resonance (ESR) experiments. At high temperature the system crystallizes in an orthorhombic structure. The resistivity value, ρ ≃ 0.05 Ω cm at 500 K, indicates a metallic behaviour, while the Curie-Weiss dependence of χ(T) and the thermal evolution of the ESR parameters are very well described by a model that considers a system conformed by localized Mn(4+) cores, [Formula: see text], and itinerant, eg, electrons. The strong coupling between t2g and eg electrons results in an enhanced Curie constant and an FM Curie-Weiss temperature that overcomes the AFM interactions between the [Formula: see text] cores. A transition to a more distorted phase is observed at T ≈ 500 K and signatures of localization of the eg electrons appear in the χ(T) behaviour below 300 K. A new Curie-Weiss regime is observed, where the Curie-constant value is consistent with dimer formation. Based on mean-field calculations, the dimer formation is predicted as a function of the interaction strength between the t2g and eg electrons.

Open Science: a first step towards Science Communication

NASA Astrophysics Data System (ADS)

Grigorov, Ivo; Tuddenham, Peter

2015-04-01

As Earth Science communicators gear up to adopt the new tools and captivating approaches to engage citizen scientists, budding entrepreneurs, policy makers and the public in general, researchers have the responsibility, and opportunity, to fully adopt Open Science principles and capitalize on its full societal impact and engagement. Open Science is about removing all barriers to basic research, whatever its formats, so that it can be freely used, re-used and re-hashed, thus fueling discourse and accelerating generation of innovative ideas. The concept is central to EU's Responsible Research and Innovation philosophy, and removing barriers to basic research measurably contributes to engaging citizen scientists into the research process, it sets the scene for co-creation of solutions to societal challenges, and raises the general science literacy level of the public. Despite this potential, only 50% of today's basic research is freely available. Open Science can be the first passive step of communicating marine research outside academia. Full and unrestricted access to our knowledge including data, software code and scientific publications is not just an ethical obligation, but also gives solid credibility to a more sophisticated communication strategy on engaging society. The presentation will demonstrate how Open Science perfectly compliments a coherent communication strategy for placing Marine Research in societal context, and how it underpin an effective integration of Ocean & Earth Literacy principles in standard educational, as well mobilizing citizen marine scientists, thus making marine science Open Science.

Citizen science has advanced science for hundreds of years, contributed to many peer-reviewed articles, and informed land management decisions and policies across the United States. Over the last 10 years, citizen science has grown immensely in the United States and many other countries. Here, we show how citizen science is a powerful tool for tackling many of the challenges faced in the field of conservation biology. We describe the two interwoven paths by which citizen science can improve conservation efforts, natural resource management, and environmental protection. The first path includes building scientific knowledge, while the other path involves informing policy and encouraging public action. We explore how citizen science is currently used and describe the investments needed to create a citizen science program. We find that:Citizen science already contributes substantially to many domains of science, including conservation, natural resource, and environmental science. Citizen science informs natural resource management, environmental protection, and policymaking and fosters public input and engagement.Many types of projects can benefit from citizen science, but one must be careful to match the needs for science and public involvement with the right type of citizen science project and the right method of public participation.Citizen science is a rigorous process of scientific discovery, indistinguishable from conventional science apart from the participation of volunteers. When properly designed, carried out, and evaluated, citizen science can provide sound science, efficiently generate high-quality data, and help solve problems.

Parents' and children's beliefs about science and science careers

NASA Astrophysics Data System (ADS)

Telfer, Jo Ann

Science has become an essential part of our cultural, social and technological lives. Around the world economic policies are giving high priority to the production of new knowledge generated by scientists. Unfortunately, gender equality in science-related careers has not been achieved. Women who possess high intellectual and personal abilities are succeeding in many occupational areas previously closed to all but the most impervious women, but females are still largely underrepresented in physical science and mathematics related careers. The purpose of the current study was to examine the reasons for this underrepresentation of women in science-related careers. Participants included a subset of mothers (n = 174), fathers (n = 132) and children (n = 186) from a larger study at the University of Calgary entitled Gender Differences in Student Participation and Achievement in the Sciences: Choice or Chance ? Telephone interview and survey questionnaire data were examined for gender and achievement level differences, focusing on high achieving girls who are most likely to succeed in science-related careers. Relationships between parents' and children's responses were also examined using the theoretical construct of Eccles' Model of Achievement Related Choices. Gathered data were studied using factor analysis, multivariate analysis of variance, analysis of variance as well as categorical analysis of qualitative results. Girls and boys achieved similar grades on all academic measures except the Alberta Science Achievement Test, where boys scored significantly higher than girls. Mothers, fathers, and children indicated positive attitudes towards science, no gender stereotyping about science and science careers, and gender neutral beliefs about science achievement. Gender differences were found in expressed possibility of future career choice. Science/Professional Careers were viewed as male occupations by mothers and children, but as gender neutral occupations by fathers

Qualitative science policy.

PubMed

Mitcham, Carl

2007-12-01

Qualitative research struggles against a tide of quantitative methods. To assist in this struggle, it is useful to consider the historical and philosophical origins of quantitative methods as well as criticisms that have been raised against them. Although these criticisms have often been restricted to discussions in the philosophy of science, they have become increasingly prominent in debates regarding science policy. This article thus reviews current science policy debates concerning scientific autonomy and the linear model of science-society relationships. Then, having considered the multiple meanings of quality, it argues for a science policy reassessment of quantitative research, for deeper engagements between science policy and the social sciences, and finally, for a more explicit alliance between science policy and qualitative methods.

Structural and magnetic properties of RTiNO{sub 2} (R=Ce, Pr, Nd) perovskite nitride oxides

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

Porter, Spencer H.; Huang, Zhenguo, E-mail: zhenguo@uow.edu.au; Cheng, Zhenxiang

2015-03-15

Neutron powder diffraction indicates that CeTiNO{sub 2} and PrTiNO{sub 2} crystallize with orthorhombic Pnma symmetry (Ce: a=5.5580(5), b=7.8369(7), and c=5.5830(4) Å; Pr: a=5.5468(5), b=7.8142(5), and c=5.5514(5) Å) as a result of a{sup –}b{sup +}a{sup –} tilting of the titanium-centered octahedra. Careful examination of the NPD data, confirms the absence of long range anion order in both compounds, while apparent superstructure reflections seen in electron diffraction patterns provide evidence for short range anion order. Inverse magnetic susceptibility plots reveal that the RTiNO{sub 2} (R=Ce, Pr, Nd) compounds are paramagnetic with Weiss constants that vary from −28 to −42 K. Effective magneticmore » moments for RTiNO{sub 2} (R=Ce, Pr, Nd) are 2.43 μ{sub B}, 3.63 μ{sub B}, and 3.47 μ{sub B}, respectively, in line with values expected for free rare-earth ions. Deviations from Curie–Weiss behavior that occur below 150 K for CeTiNO{sub 2} and below 30 K for NdTiNO{sub 2} are driven by magnetic anisotropy, spin–orbit coupling, and crystal field effects. - Graphical abstract: The structure and magnetism of the oxide nitride perovskites RTiNO{sub 2} (R=Ce, Pr, Nd) have been explored. The average symmetry is shown to be Pnma with a random distribution of oxide and nitride ions and a{sup −}b{sup +}a{sup −} tilting of the titanium-centered octahedra, but electron diffraction shows evidence for short range anion order. All three compounds are paramagnetic but deviations from the Curie Weiss law are seen below 150 K for R=Ce and below 30 K for R=Nd. - Highlights: • The oxide nitride perovskites RTiNO{sub 2} (R=Ce, Pr) have been prepared and their structures determined. • Diffraction measurements indicate short range cis-order of O and N, but no long range order. • Compounds are paramagnetic with Weiss constants that vary from −28 to −42 K. • CeTiO{sub 2}N and NdTiO{sub 2}N deviate from Curie–Weiss behavior below 150 and 30 K

NASA Astrophysics Data System (ADS)

Riedinger, Kelly; Marbach-Ad, Gili; Randy McGinnis, J.; Hestness, Emily; Pease, Rebecca

2011-02-01

We investigated curricular and pedagogical innovations in an undergraduate science methods course for elementary education majors at the University of Maryland. The goals of the innovative elementary science methods course included: improving students' attitudes toward and views of science and science teaching, to model innovative science teaching methods and to encourage students to continue in teacher education. We redesigned the elementary science methods course to include aspects of informal science education. The informal science education course features included informal science educator guest speakers, a live animal demonstration and a virtual field trip. We compared data from a treatment course ( n = 72) and a comparison course ( n = 26). Data collection included: researchers' observations, instructors' reflections, and teacher candidates' feedback. Teacher candidate feedback involved interviews and results on a reliable and valid Attitudes and Beliefs about the Nature of and the Teaching of Science instrument. We used complementary methods to analyze the data collected. A key finding of the study was that while benefits were found in both types of courses, the difference in results underscores the need of identifying the primary purpose for innovation as a vital component of consideration.

Compared to national numbers, South Dakota has a higher proportion of students interested in science, technology, engineering, and mathematics (STEM) fields. Interest in science can be influenced by exposure to science through formal and informal learning. Informal science activities (including exposures and participation) have been found to elicit higher levels of interest in science, likely impacting one's attitude towards science overall. The current study goal is to better understand the levels and relationships of attitude, exposure, and participation in science that were present among students and parents attending a free science festival. The project collected survey data from 65 students and 79 parents attending a science festival ranging from age 6 to 65. Informal science participation is significantly related to science attitudes in students and informal science exposure is not. No relationship was found for parents between science attitudes and participation. Students who indicated high levels of informal science participation (i.e., reading science-themed books) were positively related to their attitudes regarding science. However, informal science exposures, such as attending the zoo or independently visiting a science lab, was not significantly associated with positive attitudes towards science.

Science as a Second Language: Acquiring Fluency through Science Enterprises

NASA Astrophysics Data System (ADS)

Shope, R. E.

2012-12-01

Science Enterprises are problems that students genuinely want to solve, questions that students genuinely want to answer, that naturally entail reading, writing, exploration, investigation, and discussion. Engaging students in personally-relevant science enterprises provides both a diagnostic opportunity and a context for providing students the comprehensible input they need. We can differentiate instruction by creating science enterprise zones that are set up for the incremental increase in challenge for the students. Comprehensible input makes reachable, those just-out-of-reach concepts in the mix of the familiar and the new. We explore a series of science enterprise tools that have been developed and implemented in the context of informal science education projects that have reached over 10,000 urban youth in the Greater Los Angles area over the past six years. 1) The ED3U Science Inquiry Model, a learning cycle model that accounts for conceptual change; 2) The ¿NQUIRY Wheel, a compass of scientific inquiry strategies; 3) Inquiry Science Expeditions, a way of laying out a science learning environment, emulating a field and lab research collaboratory; 4) The Science Educative Experience Scale, a diagnostic measure of the quality of the science learning experience; and 5) Science Mimes, participatory enactment of science understanding. Practical examples of Science Enterprises will be presented, including a range of projects: Watershed Ecology; Astrobiology; Mars Rovers; Planetary Science; Icy Worlds. BACKGROUND: Language Acquisition is an informal process that occurs in the midst of exploring, solving problems, seeking answers to questions, playing, reading for pleasure, conversing, discussing, where the focus is not specifically on language development, but on the activity, which is of interest to the participant. Language Learning is a formal education process, the language arts aspect of the school day: the direct teaching of reading, writing, grammar

Home culture, science, school and science learning: is reconciliation possible?

NASA Astrophysics Data System (ADS)

Tan, Aik-Ling

2011-09-01

In response to Meyer and Crawford's article on how nature of science and authentic science inquiry strategies can be used to support the learning of science for underrepresented students, I explore the possibly of reconciliation between the cultures of school, science, school science as well as home. Such reconciliation is only possible when science teachers are cognizant of the factors affecting the cultural values and belief systems of underrepresented students. Using my experience as an Asian learner of WMS, I suggest that open and honest dialogues in science classrooms will allow for greater clarity of the ideals that WMS profess and cultural beliefs of underrepresented students. This in-depth understanding will eliminate guesswork and unrealistic expectations and in the process promote tolerance and acceptance of diversity in ways of knowing.

Constructivism in Science and Science Education: A Philosophical Critique

NASA Astrophysics Data System (ADS)

Nola, Robert

This paper argues that constructivist science education works with an unsatisfactory account of knowledge which affects both its account of the nature of science and of science education. The paper begins with a brief survey of realism and anti-realism in science and the varieties of constructivism that can be found. In the second section the important conception of knowledge and teaching that Plato develops in the Meno is contrasted with constructivism. The section ends with an account of the contribution that Vico (as understood by constructivists), Kant and Piaget have made to constructivist doctrines. Section three is devoted to a critique of the theory of knowledge and the anti-realism of von Glaserfeld. The final section considers the connection, or lack of it, between the constructivist view of science and knowledge and the teaching of science.

International studies have shown that interest in science and technology among primary and secondary school students in Western European countries is low and seems to be decreasing. In many countries outside Europe, and especially in developing countries, interest in science and technology remains strong. As part of the large-scale European Union funded `Science Education for Diversity' project, a questionnaire probing potential reasons for this difference was completed by students in the UK, Netherlands, Turkey, Lebanon, India and Malaysia. This questionnaire sought information about favourite courses, extracurricular activities and views on the nature of science. Over 9,000 students aged mainly between 10 and 14 years completed the questionnaire. Results revealed that students in countries outside Western Europe showed a greater interest in school science, in careers related to science and in extracurricular activities related to science than did Western European students. Non-European students were also more likely to hold an empiricist view of the nature of science and to believe that science can solve many problems faced by the world. Multilevel analysis revealed a strong correlation between interest in science and having such a view of the Nature of Science.

Online citizen science games: Opportunities for the biological sciences.

PubMed

Curtis, Vickie

2014-12-01

Recent developments in digital technologies and the rise of the Internet have created new opportunities for citizen science. One of these has been the development of online citizen science games where complex research problems have been re-imagined as online multiplayer computer games. Some of the most successful examples of these can be found within the biological sciences, for example, Foldit, Phylo and EteRNA. These games offer scientists the opportunity to crowdsource research problems, and to engage with those outside the research community. Games also enable those without a background in science to make a valid contribution to research, and may also offer opportunities for informal science learning.

2012-01-01

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.

Studying Students' Science Literacy: Non-Scientific Beliefs and Science Literacy Measures

NASA Astrophysics Data System (ADS)

Impey, C.; Buxner, S.

2015-11-01

We have been conducting a study of university students' science literacy for the past 24 years. Based on the work of the National Science Board's ongoing national survey of the US public, we have administered the same survey to undergraduate science students at the University of Arizona almost every year since 1989. Results have shown relatively little change in students' overall science literacy, descriptions of science, and knowledge of basic science topics for almost a quarter of a century despite an increase in education interventions, the rise of the internet, and increased access to knowledge. Several trends do exist in students' science literacy and descriptions of science. Students who exhibit beliefs in non-scientific phenomenon (e.g., lucky numbers, creationism) consistently have lower science literacy scores and less correct descriptions of scientific phenomenon. Although not surprising, our results support ongoing efforts to help students generate evidence based thinking.

Science of learning is learning of science: why we need a dialectical approach to science education research

NASA Astrophysics Data System (ADS)

Roth, Wolff-Michael

2012-06-01

Research on learning science in informal settings and the formal (sometimes experimental) study of learning in classrooms or psychological laboratories tend to be separate domains, even drawing on different theories and methods. These differences make it difficult to compare knowing and learning observed in one paradigm/context with those observed in the other. Even more interestingly, the scientists studying science learning rarely consider their own learning in relation to the phenomena they study. A dialectical, reflexive approach to learning, however, would theorize the movement of an educational science (its learning and development) as a special and general case—subject matter and method—of the phenomenon of learning (in/of) science. In the dialectical approach to the study of science learning, therefore, subject matter, method, and theory fall together. This allows for a perspective in which not only disparate fields of study—school science learning and learning in everyday life—are integrated but also where the progress in the science of science learning coincides with its topic. Following the articulation of a contradictory situation on comparing learning in different settings, I describe the dialectical approach. As a way of providing a concrete example, I then trace the historical movement of my own research group as it simultaneously and alternately studied science learning in formal and informal settings. I conclude by recommending cultural-historical, dialectical approaches to learning and interaction analysis as a context for fruitful interdisciplinary research on science learning within and across different settings.

Review of the Draft 2014 Science Mission Directorate Science Plan

NASA Technical Reports Server (NTRS)

2013-01-01

At the request of NASA's Science Mission Directorate (SMD), the National Research Council's (NRC's) Space Studies Board (SSB) initiated a study to review a draft of the SMD's 2014 Science Plan. The request for this review was made at a time when NASA is engaged in the final stages of a comprehensive, agency-wide effort to develop a new strategic plan and at a time when NASA's budget is under considerable stress. SMD's Science Plan serves to provide more detail on its four traditional science disciplines-astronomy and astrophysics, solar and space physics (also called heliophysics), planetary science, and Earth remote sensing and related activities-than is possible in the agency-wide Strategic Plan. In conducting its review of the draft Science Plan, the Committee on the Assessment of the NASA Science Mission Directorate 2014 Science Plan was charged to comment on the following specific areas: (1) Responsiveness to the NRC's guidance on key science issues and opportunities in recent NRC reports; (2) Attention to interdisciplinary aspects and overall scientific balance; (3) Identification and exposition of important opportunities for partnerships as well as education and public outreach; (4) Integration of technology development with the science program; (5) Clarity on how the plan aligns with SMD's strategic planning process; (6) General readability and clarity of presentation; and (7) Other relevant issues as determined by the committee. The main body of the report provides detailed findings and recommendations relating to the draft Science Plan. The highest-level, crosscutting issues are summarized here, and more detail is available in the main body of the report.

The Science of Sex Differences in Science and Mathematics

PubMed Central

Halpern, Diane F.; Benbow, Camilla P.; Geary, David C.; Gur, Ruben C.; Hyde, Janet Shibley; Gernsbacher, Morton Ann

2014-01-01

Summary Amid ongoing public speculation about the reasons for sex differences in careers in science and mathematics, we present a consensus statement that is based on the best available scientific evidence. Sex differences in science and math achievement and ability are smaller for the mid-range of the abilities distribution than they are for those with the highest levels of achievement and ability. Males are more variable on most measures of quantitative and visuospatial ability, which necessarily results in more males at both high- and low-ability extremes; the reasons why males are often more variable remain elusive. Successful careers in math and science require many types of cognitive abilities. Females tend to excel in verbal abilities, with large differences between females and males found when assessments include writing samples. High-level achievement in science and math requires the ability to communicate effectively and comprehend abstract ideas, so the female advantage in writing should be helpful in all academic domains. Males outperform females on most measures of visuospatial abilities, which have been implicated as contributing to sex differences on standardized exams in mathematics and science. An evolutionary account of sex differences in mathematics and science supports the conclusion that, although sex differences in math and science performance have not directly evolved, they could be indirectly related to differences in interests and specific brain and cognitive systems. We review the brain basis for sex differences in science and mathematics, describe consistent effects, and identify numerous possible correlates. Experience alters brain structures and functioning, so causal statements about brain differences and success in math and science are circular. A wide range of sociocultural forces contribute to sex differences in mathematics and science achievement and ability—including the effects of family, neighborhood, peer, and school

Plans of Mice and Men: From Bench Science to Science Policy

Simon, Ian D.

2011-01-01

The transition from bench science to science policy is not always a smooth one, and my journey stretched as far as the unemployment line to the hallowed halls of the U.S. Capitol. While earning my doctorate in microbiology, I found myself more interested in my political activities than my experiments. Thus, my science policy career aspirations were born from merging my love of science with my interest in policy and politics. After receiving my doctorate, I accepted the Henry Luce Scholarship, which allowed me to live in South Korea for 1 year and delve into the field of science policy research. This introduction into science policy occurred at the South Korean think tank called the Science and Technology Policy Institute (STEPI). During that year, I used textbooks, colleagues, and hands-on research projects as my educational introduction into the social science of science and technology decision-making. However, upon returning to the United States during one of the worst job markets in nearly 80 years, securing a position in science policy proved to be very difficult, and I was unemployed for five months. Ultimately, it took more than a year from the end of the Luce Scholarship to obtain my next science policy position with the American Society for Microbiology Congressional Fellowship. This fellowship gave me the opportunity to work as the science and public health advisor to U.S. Senator Harry Reid. While there were significant challenges during my transition from the laboratory to science policy, those challenges made me tougher, more appreciative, and more prepared to move from working at the bench to working in the field of science policy.

In recent years, science has become inextricably linked to the political process. As such, it is more important now than ever for science to forge a better relationship with politics, for the health of both science and society. To help meet this need, the American Geophysical Union (AGU) strives to engage its members, shape policy, and inform society about the excitement of Earth and space science and its role in developing solutions for the sustainability of the planet. In June 2013, AGU held its second annual Science Policy Conference in Washington, D.C. The goal of the conference is to provide a new forum for diverse discussions and viewpoints on the challenges and opportunities of science policy, with a focus on applications of Earth and space science that serve local, national, and international communities. The meeting brought together more than 300 scientists, policy makers, industry professionals, members of the press, and other stakeholders to discuss the topics concerning the Arctic, climate change, oceans, energy, technology and infrastructure, and natural hazards science as they relate to challenges impacting society. Sessions such as 'The Water-Energy Nexus,' 'Potential for Megadisasters,' 'The Changing Ocean and Impacts on Human Health,' and 'Drowning and Drought: Agricultural Impacts of Climate Change' are examples of some of the intriguing and timely science policy issues addressed at the conference. The findings from the conference were used to develop a summary report. The report highlights key facts and figures to be used as a resource in discussions with policy makers and other stakeholders regarding the conference topics. This presentation will discuss the goals and outcomes of the conference and how the event represents one of the many ways AGU is approaching its 'Science and Society' priority objective as part of the Union's strategic plan; namely by increasing the effectiveness and recognition of AGU among policy makers as an authoritative

Congressional Science Fellow tackles science policy for U.K.

NASA Astrophysics Data System (ADS)

Moses, Julie J.

After an AGU Congressional Science Fellowship in 1997-1998,I decided to pursue science policy further. I spied an ad in the Sunday Washington Post advertising for someone with a science degree, who also had knowledge of the United Kingdom, and science policy experience on Capitol Hill. In addition to my Ph.D. from the University of California at Los Angeles and the Congressional Science Fellowship, I had spent two years in the U.K. as a post-doc at Queen Mary and Westfield College in London.I applied for the job, which was at the British Embassy in Washington, D.C., and was hired. The UK Foreign Office has a tradition of hiring many of its embassy staff locally; they consider knowledge of local politics and issues very use ful for their interests. Now I cover hard science issues, including space and the Internet for Her Majesty's Government.

This article coincides with the release of "Data-Intensive Science," co-edited by Dr. Kerstin Kleese van Dam. In the piece, Dr. Kleese van Dam explains how data-intensive science has the potential to transform not only how we do science but how quickly we can translate scientific progress into complete solutions, policies, decisions and, ultimately, economic success. In the article, she states it is clear that nations that can most effectively transform tons of scientific data into actionable knowledge are going to be the leaders in the future of science and commerce and how creating the required new insights for complex challengesmore » cannot be done without effective collaboration. Because many science domains already are unable to explore all of the data they collect (or which is relevant to their research), progress in collaborative, data-intensive science is crucial toward unlocking the potential of big data.« less

Making Philosophy of Science Education Practical for Science Teachers

Philosophy of science education can play a vital role in the preparation and professional development of science teachers. In order to fulfill this role a philosophy of science education should be made practical for teachers. First, multiple and inherently incomplete philosophies on the teacher and teaching on what, how and why should be integrated. In this paper we describe our philosophy of science education (ASSET approach) which is composed of bounded rationalism as a guideline for understanding teachers' practical reasoning, liberal education underlying the why of teaching, scientific perspectivism as guideline for the what and educational social constructivism as guiding choices about the how of science education. Integration of multiple philosophies into a coherent philosophy of science education is necessary but not sufficient to make it practical for teachers. Philosophies are still formulated at a too abstract level to guide teachers' practical reasoning. For this purpose, a heuristic model must be developed on an intermediate level of abstraction that will provide teachers with a bridge between these abstract ideas and their specific teaching situation. We have developed and validated such a heuristic model, the CLASS model in order to complement our ASSET approach. We illustrate how science teachers use the ASSET approach and the CLASS model to make choices about the what, the how and the why of science teaching.

A call for more science in forensic science.

Forensic science is critical to the administration of justice. The discipline of forensic science is remarkably complex and includes methodologies ranging from DNA analysis to chemical composition to pattern recognition. Many forensic practices developed under the auspices of law enforcement and were vetted primarily by the legal system rather than being subjected to scientific scrutiny and empirical testing. Beginning in the 1990s, exonerations based on DNA-related methods revealed problems with some forensic disciplines, leading to calls for major reforms. This process generated a National Academy of Science report in 2009 that was highly critical of many forensic practices and eventually led to the establishment of the National Commission for Forensic Science (NCFS) in 2013. The NCFS was a deliberative body that catalyzed communication between nonforensic scientists, forensic scientists, and other stakeholders in the legal community. In 2017, despite continuing problems with forensic science, the Department of Justice terminated the NCFS. Just when forensic science needs the most support, it is getting the least. We urge the larger scientific community to come to the aid of our forensic colleagues by advocating for urgently needed research, testing, and financial support.

Understandings of Nature of Science and Multiple Perspective Evaluation of Science News by Non-science Majors

Leung, Jessica Shuk Ching; Wong, Alice Siu Ling; Yung, Benny Hin Wai

2015-10-01

Understandings of nature of science (NOS) are a core component of scientific literacy, and a scientifically literate populace is expected to be able to critically evaluate science in the media. While evidence has remained inconclusive on whether better NOS understandings will lead to critical evaluation of science in the media, this study aimed at examining the correlation therein. Thirty-eight non-science majors, enrolled in a science course for non-specialists held in a local community college, evaluated three health news articles by rating the extent to which they agreed with the reported claims and providing as many justifications as possible. The majority of the participants were able to evaluate and justify their viewpoint from multiple perspectives. Students' evaluation was compared with their NOS conceptions, including the social and cultural embedded NOS, the tentative NOS, the peer review process and the community of practice. Results indicated that participants' understanding of the tentative NOS was significantly correlated with multiple perspective evaluation of science news reports of socioscientific nature (r = 0.434, p < 0.05). This moderate correlation suggested the association between understanding of the tentative NOS and multiple perspective evaluation of science in the media of socioscientific nature. However, the null result for other target NOS aspects in this study suggested a lack of evidence to assume that understanding the social dimensions of science would have significant influence on the evaluation of science in the media. Future research on identifying the reasons for why and why not NOS understandings are applied in the evaluation will move this field forward.

As sports scientists, we claim to make a significant contribution to the body of knowledge that influences athletic practice and performance. Is this the reality? At the inaugural congress of the Australian Association for Exercise and Sports Science, a panel of well-credentialed academic experts with experience in the applied environment debated the question, Does sports-science research influence practice? The first task was to define "sports-science research," and it was generally agreed that it is concerned with providing evidence that improves sports performance. When practices are equally effective, sports scientists also have a role in identifying practices that are safer, more time efficient, and more enjoyable. There were varying views on the need for sports-science research to be immediately relevant to coaches or athletes. Most agreed on the importance of communicating the results of sports-science research, not only to the academic community but also to coaches and athletes, and the need to encourage both short- and long-term research. The panelists then listed examples of sports-science research that they believe have influenced practice, as well as strategies to ensure that sports-science research better influences practice.

The emergence of e-Science over the past decade as a paradigm for Internet-based science was an inevitable evolution of science that built upon the web protocols and access patterns that were prevalent at that time, including Web Services, XML-based information exchange, machine-to-machine communication, service registries, the Grid, and distributed data. We now see a major shift in web behavior patterns to social networks, user-provided content (e.g., tags and annotations), ubiquitous devices, user-centric experiences, and user-led activities. The inevitable accrual of these social networking patterns and protocols by scientists and science projects leads to U-Science as a new paradigm for online scientific research (i.e., ubiquitous, user-led, untethered, You-centered science). U-Science applications include components from semantic e-science (ontologies, taxonomies, folksonomies, tagging, annotations, and classification systems), which is much more than Web 2.0-based science (Wikis, blogs, and online environments like Second Life). Among the best examples of U-Science are Citizen Science projects, including Galaxy Zoo, Stardust@Home, Project Budburst, Volksdata, CoCoRaHS (the Community Collaborative Rain, Hail and Snow network), and projects utilizing Volunteer Geographic Information (VGI). There are also scientist-led projects for scientists that engage a wider community in building knowledge through user-provided content. Among the semantic-based U-Science projects for scientists are those that specifically enable user-based annotation of scientific results in databases. These include the Heliophysics Knowledgebase, BioDAS, WikiProteins, The Entity Describer, and eventually AstroDAS. Such collaborative tagging of scientific data addresses several petascale data challenges for scientists: how to find the most relevant data, how to reuse those data, how to integrate data from multiple sources, how to mine and discover new knowledge in large databases, how to
