She has taught at both the primary and secondary school levels in Mumbai and Bangalore. Her research interests are environmental and science education and gender studies. She has participated in research projects that analysed textbooks for content enrichment pertaining to the environment. At the Homi Bhabha Centre for Science Education (HBCSE) Tata Institute of Fundamental Research (TIFR) Mumbai she studied aspects of gender represented in school textbooks and prepared resource material for teachers at the primary level. E-mail: J. Ramadas is Professor of science education and Centre Director of the HBCSE TIFR Mumbai India. She received an M.Sc. in physics from the Indian Institute of Technology (IIT) Kanpur in 1976 and a Ph.D. in science education from the HBCSE in 1981. Professor Ramadas is interested in cognitive studies of science learning and school science curricula. She led the development of the Homi Bhabha Curriculum for Primary Science titled ‘Small Science’ published in four languages for which she was awarded the Third World Academy of Sciences Regional Prize in 2011. Professor Ramadas served on the National Curriculum Framework 2005 Science Focus Group. She is a member of the International Union of Pure and Applied Physics (IUPAP) International Commission on Physics Education. Her research is concerned with visuospatial thinking in science including the use of diagrams and gestures. She guest-edited a special issue of the in 2009 on this emerging area of research. E-mail:

Visual representations, including photographs, sketches and schematic diagrams, are a valuable yet often neglected aspect of textbooks. Visual means of communication are particularly helpful in introducing abstract concepts in science. For effective communication, visuals and text need to be appropriately integrated within the *** study is based on an analysis of the science textbooks of the national Council of educational Research and Training (NCeRT) and the Maharashtra State Board (MSB) for Classes 3–10. We first assess these textbooks for the use of visual representations generally. Then we focus on the water cycle, looking at how this topic is treated in the school science curriculum, at the types of visual representations used, and how effectively text and visuals are integrated to teach the water cycle over the course of the school years. We conclude with some observations on the visual treatment of the water cycle in two exemplar textbooks, and examine the implications for the use of visualisation to understand the concept of the water cycle.

We report the results of a comprehensive copy number variant (CNV) reanalysis of 9171 exome sequencing datasets from 5757 families affected by a rare disease (RD). The data reanalysed was extremely heterogeneous, having been generated using 28 different enrichment kits by 42 different research groups across europe partnering in the Solve-RD project. each research group had previously undertaken their own analysis of the data but failed to identify disease-causing variants. We applied three CNV calling algorithms to maximise sensitivity, and rare CNVs overlapping genes of interest, provided by four partner european Reference Networks, were taken forward for interpretation by clinical experts. This reanalysis has resulted in a molecular diagnosis being provided to 51 families in this sample, with ClinCNV performing the best of the three algorithms. We also identified partially explanatory pathogenic CNVs in a further 34 individuals. This work illustrates the value of reanalysing eS cold cases for CNVs. © The Author(s) 2024.

From Dissemination to Propagation: A New Paradigm for education Developers

Change 2017年第4期49卷 35-42页

作者： Froyd, Jeffrey e. Henderson, Charles Cole, Renée S. Friedrichsen, Debra Khatri, Raina Stanford, Courtney Jeffrey E. Froyd is a Research Professor at Texas A&M University. His research interests include sustained adoption of improvements in learning and teaching systematic reviews in engineering education evaluation of faculty campus climates and assessment of complex learning outcomes. Charles Henderson is a Professor at Western Michigan University with a joint appointment between the Department of Physics and the Mallinson Institute for Science Education. His research focuses on promoting productive changes in higher education at the individual department institution and national levels. Renée S. Cole is an Associate Professor of Chemistry at the University of Iowa. She teaches introductory and advanced courses in chemistry and runs a research program focused on the design and assessment of instructional materials and teaching strategies and faculty professional development. Debra Friedrichsen founded and operates a small consulting company. She received her Ph.D. from Oregon State University in Chemical Engineering with a dissertation focused on engineering education. Debra also has a MBA a MS and a patent for sensor development. Raina Khatri is a doctoral student in the Mallinson Institute for Science Education at Western Michigan University. Her research focus is understanding how education developers in STEM can promote sustained adoption of their innovations. Courtney Stanford is a postdoctoral researcher in the Department of Chemistry at Virginia Commonwealth University. Her current research focuses on the identification development and assessment of process skills (also known as professional skills) in active learning undergraduate STEM classrooms.

Scholarly studies and national reports document failure of current efforts to achieve broad, sustained adoption of research-based instructional practices, despite compelling bodies of evidence supporting efficacy of many of these practices. The authors of this paper argue that many change agents who are working to promote systemic adoption of these teaching practices use approaches that are characterized by what the authors call the "dissemination paradigm." A dissemination paradigm characterizes patterns of these current, failing efforts. Change agents, working within the dissemination paradigm, try to convince adopters that their innovations can help their students. efforts within the dissemination paradigm have not led, and are unlikely to lead, to systemic adoption. The authors offer the "propagation paradigm" as an alternative with the potential to produce improved results. Change agents, working within the propagation paradigm, engage with adopters early and often to understand their instructional systems and interactively develop a strong product adaptable to specific contexts.

We analyze the binary gravitational microlensing event OGLe-2017-BLG-1130 (mass ratio q ∼ 0.45), the first published case in which the binary anomaly was only detected by the Spitzer Space Telescope. This event provides strong evidence that some binary signals can be missed by observations from the ground alone but detected by Spitzer. We therefore invert the normal procedure, first finding the lens parameters by fitting the space-based data and then measuring the microlensing parallax using ground-based observations. We also show that the normal four-fold spacebased degeneracy in the single-lens case can become a weak eight-fold degeneracy in binary-lens events. Although this degeneracy is resolved in event OGLe-2017-BLG-1130, it might persist in other events. Copyright © 2018, The Authors. All rights reserved.

Development of the hardware, data analysis, and simulation techniques for large compact radio arrays dedicated to mapping the 21 cm line of neutral hydrogen gas has proven to be more difficult than imagined twenty years ago when such telescopes were first proposed. Despite tremendous technical and methodological advances, there are several outstanding questions on how to optimally calibrate and analyze such data. On the positive side, it has become clear that the outstanding issues are purely technical in nature and can be solved with sufficient development activity. Such activity will enable science across redshifts, from early galaxy evolution in the pre-reionization era to dark energy evolution at low redshift. Copyright © 2019, The Authors.

SciPy is an open source scientific computing library for the Python programming language. SciPy 1.0 was released in late 2017, about 16 years after the original version 0.1 release. SciPy has become a de facto standard for leveraging scientific algorithms in the Python programming language, with more than 600 unique code contributors, thousands of dependent packages, over 100,000 dependent repositories, and millions of downloads per year. This includes usage of SciPy in almost half of all machine learning projects on GitHub, and usage by high profile projects including LIGO gravitational wave analysis and creation of the first-ever image of a black hole (M87). The library includes functionality spanning clustering, Fourier transforms, integration, interpolation, file I/O, linear algebra, image processing, orthogonal distance regression, minimization algorithms, signal processing, sparse matrix handling, computational geometry, and statistics. In this work, we provide an overview of the capabilities and development practices of the SciPy library and highlight some recent technical developments. Copyright © 2019, The Authors.

We describe the observations and resultant galaxy cluster catalog from the 2770 deg2 SPTpol extended Cluster Survey (SPT-eCS). Clusters are identified via the Sunyaev-Zel’dovich (SZ) effect, and confirmed with a combination of archival and targeted follow-up data, making particular use of data from the Dark energy Survey (DeS). With incomplete followup we have confirmed as clusters 244 of 266 candidates at a detection significance ξ ≥ 5 and an additional 204 systems at 4 500c ∼ 4.4 × 1014M*h−701 and a median redshift of z = 0.49, and we have identified 44 strong gravitational lenses in the sample thus far. Radio data are used to characterize contamination to the SZ signal;the median contamination for confirmed clusters is predicted to be ∼1% of the SZ signal at the ξ > 4 threshold, and 10% of their measured SZ flux. We associate SZ-selected clusters, from both SPT-eCS and the SPT-SZ survey, with clusters from the DeS redMaPPer sample, and find an offset distribution between the SZ center and central galaxy in general agreement with previous work, though with a larger fraction of clusters with significant offsets. Adopting a fixed Planck-like cosmology, we measure the optical richness-to-SZ-mass (λ − M) relation and find it to be 28% shallower than that from a weak-lensing analysis of the DeS data—a difference significant at the 4 σ level—with the relations intersecting at λ = 60 . The SPT-eCS cluster sample will be particularly useful for studying the evolution of massive clusters and, in combination with DeS lensing observations and the SPT-SZ cluster sample, will be an important component of future cosmological analyses.

We study the polarisation properties of extragalactic sources at 95 and 150 GHz in the SPTpol 500 deg2 survey. We estimate the polarised power by stacking maps at known source positions, and correct for noise bias by subtracting the mean polarised power at random positions in the maps. We show that the method is unbiased using a set of simulated maps with similar noise properties to the real SPTpol maps. We find a flux-weighted mean-squared polarisation fraction hp2i = [8.9 ± 1.1] × 10−4 at 95 GHz and [6.9 ± 1.1] × 10−4 at 150 GHz for the full sample. This is consistent with the values obtained for a sub-sample of active galactic nuclei. For dusty sources, we find 95 per cent upper limits of 2> 95 −3 and 2> 150 −3. We find no evidence that the polarisation fraction depends on the source flux or observing frequency. The 1-σ upper limit on measured mean squared polarisation fraction at 150 GHz implies that extragalactic foregrounds will be subdominant to the CMB e and B mode polarisation power spectra out to at least ` . 5700 (` . 4700) and ` . 5300 (` . 3600), respectively at 95 (150) GHz.

We cross-correlate galaxy weak lensing measurements from the Dark energy Survey (DeS) year-one data with a cosmic microwave background (CMB) weak lensing map derived from South Pole Telescope (SPT) and Planck data, with an effective overlapping area of 1289 deg2. With the combined measurements from four source galaxy redshift bins, we obtain a detection significance of 5.8σ. We fit the amplitude of the correlation functions while fixing the cosmological parameters to a fiducial ΛCDM model, finding A=0.99±0.17. We additionally use the correlation function measurements to constrain shear calibration bias, obtaining constraints that are consistent with previous DeS analyses. Finally, when performing a cosmological analysis under the ΛCDM model, we obtain the marginalized constraints of Ωm=0.261−0.051+0.070 and S8≡σ8Ωm/0.3=0.660−0.100+0.085. These measurements are used in a companion work that presents cosmological constraints from the joint analysis of two-point functions among galaxies, galaxy shears, and CMB lensing using DeS, SPT, and Planck data.
