  4. Crew Activity Analyzer

    NASA Technical Reports Server (NTRS)

    Murray, James; Kirillov, Alexander

    2008-01-01

    The crew activity analyzer (CAA) is a system of electronic hardware and software for automatically identifying patterns of group activity among crew members working together in an office, cockpit, workshop, laboratory, or other enclosed space. The CAA synchronously records multiple streams of data from digital video cameras, wireless microphones, and position sensors, then plays back and processes the data to identify activity patterns specified by human analysts. The processing greatly reduces the amount of time that the analysts must spend in examining large amounts of data, enabling the analysts to concentrate on subsets of data that represent activities of interest. The CAA has potential for use in a variety of governmental and commercial applications, including planning for crews for future long space flights, designing facilities wherein humans must work in proximity for long times, improving crew training and measuring crew performance in military settings, human-factors and safety assessment, development of team procedures, and behavioral and ethnographic research. The data-acquisition hardware of the CAA (see figure) includes two video cameras: an overhead one aimed upward at a paraboloidal mirror on the ceiling and one mounted on a wall aimed in a downward slant toward the crew area. As many as four wireless microphones can be worn by crew members. The audio signals received from the microphones are digitized, then compressed in preparation for storage. Approximate locations of as many as four crew members are measured by use of a Cricket indoor location system. [The Cricket indoor location system includes ultrasonic/radio beacon and listener units. A Cricket beacon (in this case, worn by a crew member) simultaneously transmits a pulse of ultrasound and a radio signal that contains identifying information. Each Cricket listener unit measures the difference between the times of reception of the ultrasound and radio signals from an identified beacon

  14. Analyzing profiles, predictors, and consequences of student engagement dispositions.

    PubMed

    Lawson, Michael A; Masyn, Katherine E

    2015-02-01

    Drawing from a nationally representative sample of 12,760 students attending public high schools in the United States, this study used latent class analysis (LCA) to analyze profiles, predictors, and consequences of student engagement dispositions. A student engagement disposition is an umbrella concept. It encompasses students' identification with school together with their academic competencies and overall educational aspirations. Six subpopulation profiles of engagement dispositions were culled from the data using LCA. These profiles included students who possessed "model student" attributes as well as others whose school experiences reflected ambivalence and disidentification. Where practice and policy are concerned, findings regarding the characteristics and consequences of each profile can be used by researchers, practitioners, and policy makers to facilitate tailored intervention planning as well as more nuanced policy development.

  15. Analyzing learning during Peer Instruction dialogues: A resource activation framework

    NASA Astrophysics Data System (ADS)

    Wood, Anna K.; Galloway, Ross K.; Hardy, Judy; Sinclair, Christine M.

    2014-12-01

    Peer Instruction (PI) is an evidence based pedagogy commonly used in undergraduate physics instruction. When asked questions designed to test conceptual understanding, it has been observed that the proportion of students choosing the correct answer increases following peer discussion; however, relatively little is known about what takes place during these discussions or how they are beneficial to the processes of learning physics [M. C. James and S. Willoughby, Am. J. Phys. 79, 123 (2011)]. In this paper a framework for analyzing PI discussions developed through the lens of the "resources model" [D. Hammer, Am. J. Phys. 64, 1316 (1996); D. Hammer et al., Information Age Publishing (2005)] is proposed. A central hypothesis for this framework is that the dialogue with peers plays a crucial role in activating appropriate cognitive resources, enabling the students to see the problem differently, and therefore to answer the questions correctly. This framework is used to gain greater insights into the PI discussions of first year undergraduate physics students at the University of Edinburgh, UK, which were recorded using Livescribe Smartpens. Analysis of the dialogues revealed three different types of resource activation corresponding to increasing cognitive grain size. These were activation of knowledge elements, activation of linkages between knowledge elements, and activation of control structures (epistemic games and epistemological frames). Three case studies are examined to illustrate the role that peer dialogue plays in the activation of these cognitive resources in a PI session. The implications for pedagogical practice are discussed.

  16. Analyzing students' attitudes towards science during inquiry-based lessons

    NASA Astrophysics Data System (ADS)

    Kostenbader, Tracy C.

    Due to the logistics of guided-inquiry lesson, students learn to problem solve and develop critical thinking skills. This mixed-methods study analyzed the students' attitudes towards science during inquiry lessons. My quantitative results from a repeated measures survey showed no significant difference between student attitudes when taught with either structured-inquiry or guided-inquiry lessons. The qualitative results analyzed through a constant-comparative method did show that students generate positive interest, critical thinking and low level stress during guided-inquiry lessons. The qualitative research also gave insight into a teacher's transition to guided-inquiry. This study showed that with my students, their attitudes did not change during this transition according to the qualitative data however, the qualitative data did how high levels of excitement. The results imply that students like guided-inquiry laboratories, even though they require more work, just as much as they like traditional laboratories with less work and less opportunity for creativity.

  20. Model Based Reasoning by Introductory Students When Analyzing Earth Systems and Societal Challenges

    NASA Astrophysics Data System (ADS)

    Holder, L. N.; Herbert, B. E.

    2014-12-01

    Understanding how students use their conceptual models to reason about societal challenges involving societal issues such as natural hazard risk assessment, environmental policy and management, and energy resources can improve instructional activity design that directly impacts student motivation and literacy. To address this question, we created four laboratory exercises for an introductory physical geology course at Texas A&M University that engages students in authentic scientific practices by using real world problems and issues that affect societies based on the theory of situated cognition. Our case-study design allows us to investigate the various ways that students utilize model based reasoning to identify and propose solutions to societally relevant issues. In each of the four interventions, approximately 60 students in three sections of introductory physical geology were expected to represent and evaluate scientific data, make evidence-based claims about the data trends, use those claims to express conceptual models, and use their models to analyze societal challenges. Throughout each step of the laboratory exercise students were asked to justify their claims, models, and data representations using evidence and through the use of argumentation with peers. Cognitive apprenticeship was the foundation for instruction used to scaffold students so that in the first exercise they are given a partially completed model and in the last exercise students are asked to generate a conceptual model on their own. Student artifacts, including representation of earth systems, representation of scientific data, verbal and written explanations of models and scientific arguments, and written solutions to specific societal issues or environmental problems surrounding earth systems, were analyzed through the use of a rubric that modeled authentic expertise and students were sorted into three categories. Written artifacts were examined to identify student argumentation and

  6. Yes, High School Students Can Analyze Chandra Data

    NASA Astrophysics Data System (ADS)

    Keohane, J. W.; Clearfield, C. R.; Olbert, C. M.

    2002-12-01

    For the past two years, high school students at the North Carolina School of Science and Math (NCSSM) have worked with new and archival Chandra data, and have produced interesting scientific results. These results have included one refereed paper in the Ap.J., and about a dozen presentations at scientific meetings (including three at this meeting). The students were selected, based on interest, from the junior class at NCSSM, to stay on campus and work intensively for 2 to 4 weeks over the summer. Each team of students selected an object with public Chandra ACIS data, and were taught how to produce data products such as images and spectra, as well as conduct a literature search. In most cases, a paper had already been published using those data, and the students were usually able to reproduce the results. As the students waded through the literature, they would search for a theory to test or an interesting new phenomenon. Often the students would request an image in another wavelength to compare in detail to the Chandra data. After the summer, many students continued to work throughout the following fall semester, producing a paper for submission to the Siemens Westinghouse Science and Technology Competition by the beginning of October. In the process of conducting research, the students learn to apply many physics concepts, and learn valuable scientific research and writing skills. Those students that choose to continue with astrophysics can often dive directly into a high-level research project immediately when they arrive at college. These programs have been funded by NASA, through E/PO grants attached to parent research grants.

    2008-10-01

    Writing is valued as an essential skill in nursing education. However, the evaluation of written scholarly work is challenging. Limited nursing literature addressing issues or strategies associated with evaluation exists. The purpose of this study was to describe and evaluate differences that exist in the evaluation of a standardized written paper. The study included a sample of 47 graduate nursing students enrolled in a nursing education course. Participants were asked to grade a mock paper as part of a course assignment; their work was retained for data analysis. Wide variability in scoring and comments on the paper were noted; significantly lower scores were assigned by participants who had experience teaching in academic settings. The majority of written comments made by participants were related to grammar and American Psychological Association formatting or citation problems. Further research is needed to better understand paper evaluation practices of nursing faculty.

    Krumhansl, K.; Krumhansl, R.; Brown, C.; DeLisi, J.; Kochevar, R.; Sickler, J.; Busey, A.; Mueller-Northcott, J.; Block, B.

    2013-12-01

    The collection of large quantities of scientific data has not only transformed science, but holds the potential to transform teaching and learning by engaging students in authentic scientific work. Furthermore, it has become imperative in a data-rich world that students gain competency in working with and interpreting data. The Next Generation Science Standards reflect both the opportunity and need for greater integration of data in science education, and emphasize that both scientific knowledge and practice are essential elements of science learning. The process of enabling access by novice learners to data collected and used by experts poses significant challenges, however, recent research has demonstrated that barriers to student learning with data can be overcome by the careful design of data access and analysis tools that are specifically tailored to students. A group of educators at Education Development Center, Inc. (EDC) and scientists at Stanford University's Hopkins Marine Station are collaborating to develop and test a model for student engagement with scientific data using a web-based platform. This model, called Ocean Tracks: Investigating Marine Migrations in a Changing Ocean, provides students with the ability to plot and analyze tracks of migrating marine animals collected through the Tagging of Pacific Predators program. The interface and associated curriculum support students in identifying relationships between animal behavior and physical oceanographic variables (e.g. SST, chlorophyll, currents), making linkages between the living world and climate. Students are also supported in investigating possible sources of human impact to important biodiversity hotspots in the Pacific Ocean. The first round of classroom testing revealed that students were able to easily access and display data on the interface, and collect measurements from the animal tracks and oceanographic data layers. They were able to link multiple types of data to draw powerful

    Jones, Stan; Harrell, J. W.; Horton, C. E.

    2007-05-01

    As researchers learn better ways to promote student learning in introductory physics, students learn better ways of circumventing these strategies. Many students remain motivated primarily to find the lowest energy output required to pass a course rather than to actually work at learning physics. We are redesigning our introductory courses, which are taught in a studio format, under the assumption that most students will do only the things they get credit for. By offering incentives for students to participate actively in the learning process, we expect to see an improvement in student performance. This poster describes both the studio format and the teaching strategies being implemented.

  3. Activity theory as a framework for analyzing and redesigning work.

    PubMed

    Engeström, Y

    2000-07-01

    Cultural-historical activity theory is a new framework aimed at transcending the dichotomies of micro- and macro-, mental and material, observation and intervention in analysis and redesign of work. The approach distinguishes between short-lived goal-directed actions and durable, object-oriented activity systems. A historically evolving collective activity system, seen in its network relations to other activity systems, is taken as the prime unit of analysis against which scripted strings of goal-directed actions and automatic operations are interpreted. Activity systems are driven by communal motives that are often difficult to articulate for individual participants. Activity systems are in constant movement and internally contradictory. Their systemic contradictions, manifested in disturbances and mundane innovations, offer possibilities for expansive developmental transformations. Such transformations proceed through stepwise cycles of expansive learning which begin with actions of questioning the existing standard practice, then proceed to actions of analyzing its contradictions and modelling a vision for its zone of proximal development, then to actions of examining and implementing the new model in practice. New forms of work organization increasingly require negotiated 'knotworking' across boundaries. Correspondingly, expansive learning increasingly involves horizontal widening of collective expertise by means of debating, negotiating and hybridizing different perspectives and conceptualizations. Findings from a longitudinal intervention study of children's medical care illuminate the theoretical arguments.

  12. An Alternative Method for Analyzing Active Multiplicity Data.

    SciTech Connect

    Pickrell, M. M.

    2005-01-01

    The authors have developed a novel method for analyzing active neutron multiplicity data. The conventional method was derived from the standard passive multiplicity equations known as the point model. The approach was to substitute a term consisting of the product of the interrogation source strength, the coupling coefficient, and the sample mass for the product term of the sample mass and the fission rate: I{kappa}{sub c}m {yields} F{sub 0}m, where I is the source strength, {kappa}{sub c} is the coupling coefficient, m is the sample mass and F is the fission rate. Note that the sample mass, m, refers to the fissile material (e.g. {sup 235}U) in the active case and fertile material (e.g. {sup 240}Pu{sub eff}) in the passive case. In addition, the spontaneous fission multiplicity coefficients, {nu}{sub s}, were replaced with the induced fission multiplicity coefficients, {nu}{sub i}. This model has several drawbacks. The most significant is that the coupling coefficient, {kappa}{sub c}, varies significantly with the multiplication. As a consequence, there is not a clear linear relationship between the doubles rate and the sample mass, nor is there a clear linear relationship between the multiplication-corrected doubles rate and the sample mass. This problem has limited the application of active neutron multiplicity counting. They propose here a novel approach to deriving the multiplicity equations. A different substitution is made in the point model equations. The value of alpha is replaced with a new term, alpha-prime: {alpha} {yields} {alpha}{prime} {triple_bond} {alpha} + {kappa}{sub p}I/Fm{sub 0}{nu}{sub s1}. There are several benefits to this approach, but most significant is that the new coupling coefficient, {kappa}{sub p}, remains constant. In this paper they will establish the general physics justification why this different substitution is appropriate. They will derive the new point model equations for active neutron multiplicity starting from the original

    Stratford, Steven J.; Krajcik, Joseph; Soloway, Elliot

    1998-09-01

    In this paper, we explore dynamic modeling as an opportunity for students to think about the science content they are learning. We examined the "Cognitive Strategies for Modeling" (CSMs) in which students engaged as they created dynamic models. We audio- and videotape-recorded eight pairs of ninth grade science students and analyzed their conversations and actions. In analyzing appropriate objects and factors for their model, some students merely enumerated potential factors whereas others engaged in rich, substantial, mindful analysis. In reasoning about their models, students discussed relationships in depth, concentrated only on the most important key relationships, or encountered difficulty distinguishing between causal and correlational relationships. In synthesizing working models, students mapped their model to aid visualization, focused on their goal, or talked about their model's appearance or form. Students attempted to articulate explanations for their relationships, but sometimes their explanations were shallow. In testing their models, some students tested thoroughly but only a few persisted in debugging their model's behavior so that it matched their expectations. In our conclusion we suggest that creating dynamic models has great potential for use in classrooms to engage students in thought about science content, particularly in those thinking strategies best fostered by dynamic modeling: analysis, relational reasoning, synthesis, testing and debugging, and making explanations.

  2. Earth Exploration Toolbook Workshops: Helping Teachers and Students Analyze Web-based Scientific Data

    NASA Astrophysics Data System (ADS)

    McAuliffe, C.; Ledley, T.; Dahlman, L.; Haddad, N.

    2007-12-01

    One of the challenges faced by Earth science teachers, particularly in K-12 settings, is that of connecting scientific research to classroom experiences. Helping teachers and students analyze Web-based scientific data is one way to bring scientific research to the classroom. The Earth Exploration Toolbook (EET) was developed as an online resource to accomplish precisely that. The EET consists of chapters containing step-by-step instructions for accessing Web-based scientific data and for using a software analysis tool to explore issues or concepts in science, technology, and mathematics. For example, in one EET chapter, users download Earthquake data from the USGS and bring it into a geographic information system (GIS), analyzing factors affecting the distribution of earthquakes. The goal of the EET Workshops project is to provide professional development that enables teachers to incorporate Web-based scientific data and analysis tools in ways that meet their curricular needs. In the EET Workshops project, Earth science teachers participate in a pair of workshops that are conducted in a combined teleconference and Web-conference format. In the first workshop, the EET Data Analysis Workshop, participants are introduced to the National Science Digital Library (NSDL) and the Digital Library for Earth System Education (DLESE). They also walk through an Earth Exploration Toolbook (EET) chapter and discuss ways to use Earth science datasets and tools with their students. In a follow-up second workshop, the EET Implementation Workshop, teachers share how they used these materials in the classroom by describing the projects and activities that they carried out with students. The EET Workshops project offers unique and effective professional development. Participants work at their own Internet-connected computers, and dial into a toll-free group teleconference for step-by-step facilitation and interaction. They also receive support via Elluminate, a Web

    In this poster, we present the results of several activities developed for the general science student to explore infrared light. The first activity involved measuring infrared radiation using an updated version of Newton's experiment of splitting white light and finding IR radiation. The second used Leslie's cube to allow students to observe different radiators, while the third used a modern infrared thermometer to measure and identify IR sources in an enclosed box. The last activity involved students making false-color images from narrow-band filter images from data sets from Spitzer Space Telescope, STScI Digitized Sky Survey and other sources. Using computer programs like Adobe Photoshop and free software such as ds9, Spot and Leopard, poster-like images were created by the students. This research is funded by the Spitzer Science Center (SSC) and the National Optical Astronomy Observatory (NOAO).

    1993-01-01

    This paper presents a signal processing system that: (1) provides an efficient and reliable instrument for investigating the activity of neuronal assemblies in the brain; and (2) demonstrates the feasibility of generating the command signals of prostheses using the activity of relevant neurons in disabled subjects. The system operates online, in a fully automated manner and can recognize the transient waveforms of several neurons in extracellular neurophysiological recordings. Optimal algorithms for detection, classification, and resolution of overlapping waveforms are developed and evaluated. Full automation is made possible by an algorithm that can set appropriate decision thresholds and an algorithm that can generate templates on-line. The system is implemented with a fast IBM PC compatible processor board that allows on-line operation.

    2016-01-01

    Background Teaching reflection and administering reflective writing assignments to students are widely practiced and discussed in medical education and health professional education. However, little is known about how medical students use language to construct their narratives. Exploring students’ linguistic patterns in their reflective writings can facilitate understanding the scope and facets of their reflections and their representational or communication approaches to share their experiences. Moreover, research findings regarding gender differences in language use are inconsistent. Therefore, we attempted to examine how females and males differ in their use of words in reflective writing within our research circumstance to detect the unique and gender-specific approaches to learning and their applications. Methods We analyzed the linguistic profiles of psychological process categories in the reflective writings of medical students and examined the difference in word usage between male and female medical students. During the first year of a clinical rotation, 60 fifth-year medical students wrote reflective narratives regarding pediatric patients and the psychosocial challenges faced by the patients and their family members. The narratives were analyzed using the Chinese version of Linguistic Inquiry and Word Count (CLIWC), a text analysis software program. Multivariate procedures were applied for statistical analysis. Results Cognitive words were most pervasive, averaging 22.16%, whereas perceptual words (2.86%) were least pervasive. Female students used more words related to positive emotions and sadness than did male students. The male students exceeded the female students only in the space category. The major limitation of this study is that CLIWC cannot directly acquire contextual text meanings; therefore, depending on the research topic, further qualitative study of the given texts might be necessary. Conclusions To enhance students’ empathy toward the

    Cha, Chae Young; Powell, Trevor; Noma, Akinori

    2011-11-01

    Bursts of repetitive action potentials are closely related to the regulation of glucose-induced insulin secretion in pancreatic β cells. Mathematical studies with simple β-cell models have established the central principle that the burst-interburst events are generated by the interaction between fast membrane excitation and slow cytosolic components. Recently, a number of detailed models have been developed to simulate more realistic β cell activity based on expanded findings on biophysical characteristics of cellular components. However, their complex structures hinder our intuitive understanding of the underlying mechanisms, and it is becoming more difficult to dissect the role of a specific component out of the complex network. We have recently developed a new detailed model by incorporating most of ion channels and transporters recorded experimentally (the Cha-Noma model), yet the model satisfies the charge conservation law and reversible responses to physiological stimuli. Here, we review the mechanisms underlying bursting activity by applying mathematical analysis tools to representative simple and detailed models. These analyses include time-based simulation, bifurcation analysis and lead potential analysis. In addition, we introduce a new steady-state I-V (ssI-V) curve analysis. We also discuss differences in electrical signals recorded from isolated single cells or from cells maintaining electrical connections within multi-cell preparations. Towards this end, we perform simulations with our detailed pancreatic β-cell model.

  15. Predicting earthquakes by analyzing accelerating precursory seismic activity

    USGS Publications Warehouse

    Varnes, D.J.

    1989-01-01

    During 11 sequences of earthquakes that in retrospect can be classed as foreshocks, the accelerating rate at which seismic moment is released follows, at least in part, a simple equation. This equation (1) is {Mathematical expression},where {Mathematical expression} is the cumulative sum until time, t, of the square roots of seismic moments of individual foreshocks computed from reported magnitudes;C and n are constants; and tfis a limiting time at which the rate of seismic moment accumulation becomes infinite. The possible time of a major foreshock or main shock, tf,is found by the best fit of equation (1), or its integral, to step-like plots of {Mathematical expression} versus time using successive estimates of tfin linearized regressions until the maximum coefficient of determination, r2,is obtained. Analyzed examples include sequences preceding earthquakes at Cremasta, Greece, 2/5/66; Haicheng, China 2/4/75; Oaxaca, Mexico, 11/29/78; Petatlan, Mexico, 3/14/79; and Central Chile, 3/3/85. In 29 estimates of main-shock time, made as the sequences developed, the errors in 20 were less than one-half and in 9 less than one tenth the time remaining between the time of the last data used and the main shock. Some precursory sequences, or parts of them, yield no solution. Two sequences appear to include in their first parts the aftershocks of a previous event; plots using the integral of equation (1) show that the sequences are easily separable into aftershock and foreshock segments. Synthetic seismic sequences of shocks at equal time intervals were constructed to follow equation (1), using four values of n. In each series the resulting distributions of magnitudes closely follow the linear Gutenberg-Richter relation log N=a-bM, and the product n times b for each series is the same constant. In various forms and for decades, equation (1) has been used successfully to predict failure times of stressed metals and ceramics, landslides in soil and rock slopes, and volcanic

    Magnetic storms are undoubtedly among the most important phenomena in space physics and also a central subject of space weather. The non-extensive Tsallis entropy has been recently introduced, as an effective complexity measure for the analysis of the geomagnetic activity Dst index. The Tsallis entropy sensitively shows the complexity dissimilarity among different "physiological" (normal) and "pathological" states (intense magnetic storms). More precisely, the Tsallis entropy implies the emergence of two distinct patterns: (i) a pattern associated with the intense magnetic storms, which is characterized by a higher degree of organization, and (ii) a pattern associated with normal periods, which is characterized by a lower degree of organization. Other entropy measures such as Block Entropy, T-Complexity, Approximate Entropy, Sample Entropy and Fuzzy Entropy verify the above mentioned result. Importantly, the wavelet spectral analysis in terms of Hurst exponent, H, also shows the existence of two different patterns: (i) a pattern associated with the intense magnetic storms, which is characterized by a fractional Brownian persistent behavior (ii) a pattern associated with normal periods, which is characterized by a fractional Brownian anti-persistent behavior. Finally, we observe universality in the magnetic storm and earthquake dynamics, on a basis of a modified form of the Gutenberg-Richter law for the Tsallis statistics. This finding suggests a common approach to the interpretation of both phenomena in terms of the same driving physical mechanism. Signatures of discrete scale invariance in Dst time series further supports the aforementioned proposal.

    This study investigated the effect of metaconceptual teaching interventions on students’ understanding of force and motion concepts. A multimethod research design including quasi-experimental design and case study designs was employed to compare the effect of the metaconceptual activities and traditional instruction and investigate students’ reactions to metaconceptual teaching interventions. The participants (45 high school students in the USA) were enrolled in one of the two physics classes instructed by the same science teacher. In the experimental group, students’ engagement in metaconceptual knowledge and processes was facilitated through various instructional activities, including poster drawing, journal writing, group debate, concept mapping, and class and group discussions. These activities were intended to facilitate students’ engagement in (a) becoming aware of their existing and past conceptions, associated beliefs, everyday experiences, and contextual differences, (b) monitoring their understanding of the new conception, the changes in ideas, and the consistency between existing and new conceptions, and (c) evaluating the relative ability of competing conceptions to explain a physical phenomenon. In the comparison group, the same content knowledge was explained by the teacher along with the use of laboratory experiments, demonstrations, and quantitative problem solving. Students’ reactions to the designed instructional activities indicated that metaconceptual teaching interventions were successful in facilitating students’ engagement in several types of metaconceptual functioning. The results showed that students in the experimental group had significantly better conceptual understanding than their counterparts in the comparison group and this positive impact remained after a period of 9 weeks.

  11. The pedagogical value of Disassemble/Analyze/Assemble (DAA) activities: Assessing the potential for motivation and transfer

    Dalrymple, Odesma Onika

    Undergraduate engineering institutions are currently seeking to improve recruiting practices and to retain engineering majors particularly by addressing what many studies document as a major challenge of poor instruction. There is an undisputed need for instructional practices that motivate students in addition to facilitating the transfer of learning beyond the classroom. Reverse engineering and product dissection, more broadly termed Disassemble/Analyze/Assemble (DAA) activities, have shown potential to address these concerns, based on the reviews of students and professors alike. DAA activities involve the systematic deconstruction of an artifact, the subsequent analysis and possible reconstruction of its components for the purpose of understanding the embodied fundamental concepts, design principles and developmental processes. These activities have been part of regular industry practice for some time; however, the systematic analysis of their benefits for learning and instruction is a relatively recent phenomenon. A number of studies have provided highly descriptive accounts of curricula and possible outcomes of DAA activities; but, relatively few have compared participants doing DAA activities to a control group doing more traditional activities. In this respect, two quasi-experiments were conducted as part of a first-year engineering laboratory, and it was hypothesized that students who engaged in the DAA activity would be more motivated and would demonstrate higher frequencies of transfer than the control. A DAA activity that required students to disassemble a single-use camera and analyze its components to discover how it works was compared to a step-by-step laboratory activity in the first experiment and a lecture method of instruction in the second experiment. In both experiments, over forty percent of the students that engaged in the DAA activity demonstrated the ability to transfer the knowledge gained about the functions of the camera's components and

    Over the past 4 school years, our team of Arctic sea ice researchers and middle school teachers has collaborated in an educational outreach activity to develop a series of earth science classes aimed at 8th grade science students. Central to the effort is an environmental observation site installed at the school, designed to closely mimic sea ice mass balance buoys deployed as part of an NSF-sponsored Arctic Observing Network (AON) project. The site located at the school collects data on air temperature, barometric pressure, snow depth, and snow and ground temperatures. Working directly with the research team over the course of the school year, students learn to collect, process, and analyze the local environmental data. Key to the experience is the students' opportunity to pose and address open-ended questions about a set of scientific data that is inherently familiar to them, since it reflects the seasonal conditions they are witnessing (e.g. the 2011-12 New England winter with no snow). During the series of classes, students are also exposed to the similar set of environmental data collected in the Arctic, via a sea ice mass balance buoy they ';adopt.' The arctic data set opens the door to discussions about climate change and its particularly dramatic affect on the arctic environment. Efforts are underway to transform this outreach project into an expanded earth science classroom module for use at other schools. Portability will require an approach that makes connections to the Arctic without a reliance on the multiple visits to the classroom by the research team (e.g. forming and facilitating partnerships with Arctic schools and field researchers via the internet). We are also evaluating the possibility of constructing low cost, portable weather stations to be used with the module.

    2015-04-01

    The study we have carried out aims to characterize 15- to 16-year-old students' learning progressions throughout the implementation of a teaching-learning sequence on the acoustic properties of materials. Our purpose is to better understand students' modeling processes about this topic and to identify how the instructional design and actual enactment influences students' learning progressions. This article presents the design principles which elicit the structure and types of modeling and inquiry activities designed to promote students' development of three conceptual models. Some of these activities are enhanced by the use of ICT such as sound level meters connected to data capture systems, which facilitate the measurement of the intensity level of sound emitted by a sound source and transmitted through different materials. Framing this study within the design-based research paradigm, it consists of the experimentation of the designed teaching sequence with two groups of students ( n = 29) in their science classes. The analysis of students' written productions together with classroom observations of the implementation of the teaching sequence allowed characterizing students' development of the conceptual models. Moreover, we could evidence the influence of different modeling and inquiry activities on students' development of the conceptual models, identifying those that have a major impact on students' modeling processes. Having evidenced different levels of development of each conceptual model, our results have been interpreted in terms of the attributes of each conceptual model, the distance between students' preliminary mental models and the intended conceptual models, and the instructional design and enactment.

    Academic results depend strongly on the individual circumstances of students: background, motivation and aptitude. We think that academic activities conducted to increase motivation must be tuned to the special situation of the students. Main goal of this work is analyze the students in the first year of the Degree in Optics and Optometry in the University of Granada and the suitability of an activity designed for those students. Initial data were obtained from a survey inquiring about the reasons to choose this degree, their knowledge of it, and previous academic backgrounds. Results show that: 1) the group is quite heterogeneous, since students have very different background. 2) Reasons to choose the Degree in Optics and Optometry are also very different, and in many cases were selected as a second option. 3) Knowledge and motivations about the Degree are in general quite low. Trying to increase the motivation of the students we designed an academic activity in which we show different topics studied in the Degree. Results show that students that have been involved in this activity are the most motivated and most satisfied with their election of the degree.

    The present study investigated the guidance provided by science teachers to resolve conflicts during socioscientific issue-based argumentation activities. A graphical representation (GR) was developed as a tool to code and analyze the dialogue interaction process. Through the GR and qualitative analysis, we identified three types of dialogue reconciling strategies. The first one consists of teacher management, in which the teacher temporarily maintains the right to speak when students get mired in an emotional rebuttal situation. The second strategy involves the use of qualifiers to identify the strengths and weaknesses of an opposing argument. The third strategy consists of providing students with guidance to keep both parties (i.e. the students taking, respectively, the affirmative and negative positions) on the same discussion topic and can be used to assist teachers with forming broad questions that prompt students to conduct deeper discussions. These reconciling strategies were beneficial in that they helped students to argue in a more reflective way.

    In an effort to inspire student interest in science and technology, scientists from the Forecast Systems Laboratory, a laboratory within the National Oceanic and Atmospheric Administration's (NOAA) Environmental Research Laboratories, and classroom teachers from the Boulder Valley School District collaborated to produce a series of classroom science activities on meteorology and atmospheric science. We call this series 'Student Activities in Meteorology,' or SAM. The goal is to provide activities that are interesting to students, and at the same time convenient and easy to use for teachers. The activity topics chosen are to incorporate trend setting scientific research and cutting edge technology. Several of the activities focus on the meteorological concerns of the Denver metropolitan area because many of NOAA's research labs are located in Boulder, where much of the research and testing for the region is performed. We believe that these activities are versatile and can be easily integrated into current science, environmental studies, health, social studies, and math curricula.

  17. Traditionally taught students learn; actively engaged students remember

    NASA Astrophysics Data System (ADS)

    Franklin, Scott V.; Sayre, Eleanor C.; Clark, Jessica W.

    2014-08-01

    A common narrative in physics education research is that students taught in lecture-based classes learn less than those taught with activity-based reformed methods. We show this narrative is simplistic and misses important dynamics of student learning. In particular, we find students of both methods show equal short-term learning gains on a conceptual question dealing with electric potential. For traditionally taught students, this learning rapidly decays on a time scale of weeks, vanishing by the time of the typical end-of-term post-test. For students in reform-based classes, however, the knowledge is retained and may even be enhanced by subsequent instruction. This difference explains the many previous pre- and post-test studies that have found minimal learning gains in lecture-based courses. Our findings suggest a more nuanced model of student learning, one that is sensitive to time-dependent effects such as forgetting and interference. In addition, the findings suggest that lecture-based courses, by incorporating aspects designed to reinforce student understanding of previously covered topics, might approach the long-term learning found in research-based pedagogies.

  18. Using Rasch model to analyze the ability of pre-university students in vector

    2015-10-01

    Evaluating students' performance only from overall examination marks does not give accurate evidence of their achievement on a particular subject. For a more detailed analysis, an instrument called Rasch Measurement Model (Rasch Model), widely used in education research, may be applied. Using the analysis map, the level of each student's ability and the level of the questions difficulty can be measured. This paper describes how the Rasch Model is used to evaluate students' achivement and performance in Vector, a subject taken by students enrolled in the Physical Science Program at the Centre for Foundation Studies in Science, University of Malaya. Usually, students' understanding of the subject and performance are assessed and examined at the end of the semester in the final examination, apart from continuous assessment done throughout the course. In order to evaluate the individual achievement and get a better and accurate evidence on the performance, 28 male and 28 female students' marks were taken randomly from the final examination results and analysed using the Rasch Model. Observation made from the map showed that more than half of the questions were categorized as difficult while the two most difficult questions could be answered correctly by 33.9% of the students. Results showed that the students performed very well and their achievement was above expectation. About 27% of the sudents could be considered as having very high ability in answering all the questions, with one student being able to answer well, obtaining perfect score. However, two students were found to be misfits since they were able to answer difficult questions but gave poor response to easy ones.

    A common presumption of secondary education is that what occurs in-school impacts students after they exit school. Previous researchers found transition-services received in school by students with autism spectrum disorder predicted their post-school success with regards to employment and independent living. This secondary analysis of the National Longitudinal Transition Study-2 sought to understand the relationship between curriculum--functional versus non-functional--and seven measures of post-school outcomes for students with autism spectrum disorder. The main results of the study include low rates of receipt of a functional curriculum, poor post-school outcomes, and the lack of relationship between curriculum and post-school outcomes for students with autism spectrum disorder.

  20. Causal-comparative study analyzing student success in hybrid anatomy and physiology courses

    NASA Astrophysics Data System (ADS)

    Levy, Jacqueline Anita

    In the biological sciences, higher student success levels are achieved in traditionally formatted, face-to-face coursework than in hybrid courses. The methodologies used to combine hybrid and in-person elements to the course need to be applied to the biological sciences to emulate the success seen in the traditional courses since the number of hybrid course offerings at community colleges are rapidly increasing. Research has delineated that creating online collaborative communities and increasing student engagement all function to increase student successful outcomes. This causal-comparative study was conducted using student data from four sections of hybrid, introductory anatomy and physiology courses over the 2011 and 2012 calendar years. The study included two sources of data: unit exam scores and student surveys. Analysis of the unit exam scores determined that there were statistically significant differences in student success and achievement by the implementation of the following web-enhanced technologies: a) discussion boards, b) Breeze, and c) Wiki tools. In the scope of this study, student success and achievement was defined as a student earning a C (70%) or higher at the completion of the course. There were a total of 29 surveys conducted per each unit during the 2012 semesters that related to the web-enhanced technologies implemented into the course: Discussion boards, BreezeRTM, and Wiki tools. Demographic data was also compiled on all of the students enrolled in the classes during this study to demonstrate that there is no specified niche or trend seen in the students enrolling for this particular course. Unit 1 was used as a baseline to compare the students from the two years. It was determined that the students were not significantly different in aptitude levels at the beginning of the courses based on their Unit 1 exam scores. Inferential statistical analysis was done to examine student success and achievement using the following tools: t-test of

  2. Understanding and Facilitating Student Bloggers: Towards a Blogging Activity Model

    NASA Astrophysics Data System (ADS)

    Derntl, Michael

    Since instructors have started recognizing the potential of Web 2.0 integration in web-based courses, blogs have been used to provide students with means of virtual communication, contribution, collaboration and community building. In this paper we aim to take another step forward by presenting and analyzing the integration of student blogs in an undergraduate computer science course on software architecture and web technologies: we implemented an LMS extension that acted as a course blog portal by collecting and displaying feeds of externally hosted blogs and logging usage data. Data analysis reveals that students who perform better academically also tend to participate more actively in the course blogosphere. Subsequently, we propose a blogging activity model, which aims to reveal and explain relationships between blogging activity variables—including peer visits, commenting and posting—to achieve a better understanding of lively blog communities in courses.

  9. Astronomy Student Activities Using Stellarium Software

    NASA Astrophysics Data System (ADS)

    Benge, Raymond D.; Tuttle, S. R.

    2012-01-01

    Planetarium programs can be used to provide a valuable learning experience for introductory astronomy students. Educational activities can be designed to utilize the capabilities of the software to display the sky, coordinates, motions in the sky, etc., in order to learn basic astronomical concepts. Most of the major textbook publishers have an option of bundling planetarium software and even laboratory activities using such software with textbooks. However, commercial planetarium software often is updated on a different schedule from the textbook revision and new edition schedule. The software updates also sometimes occur out of sync with college textbook adoption deadlines. Changes in software and activity curriculum often translate into increases costs for students and the college. To provide stability to the process, faculty at Tarrant County College have developed a set of laboratory exercises, entitled Distant Nature, using free open source Stellarium software. Stellarium is a simple, yet powerful, program that is available in formats that run on a variety of operating systems (Windows, Apple, linux). A web site was developed for the Distant Nature activities having a set version of Stellarium that students can download and install on their own computers. Also on the web site, students can access the instructions and worksheets associated with the various Stellarium based activities. A variety of activities are available to support two semesters of introductory astronomy. The Distant Nature web site has been used for one year with Tarrant County College astronomy students and is now available for use by other institutions. The Distant Nature web site is http://www.stuttle1.com/DN_Astro/index.html .

  17. Student Active Learning Methods in Physical Chemistry

    NASA Astrophysics Data System (ADS)

    Hinde, Robert J.; Kovac, Jeffrey

    2001-01-01

    We describe two strategies for implementing active learning in physical chemistry. One involves supplementing a traditional lecture course with heavily computer-based active-learning exercises carried out by cooperative groups in a department computer lab. The other uses cooperative learning almost exclusively, supplemented by occasional mini-lectures. Both approaches seemed to result in better student learning and a more positive attitude toward the subject. On the basis of our respective experiences using active learning techniques, we discuss some of the strengths of these techniques and some of the challenges we encountered using the active-learning approach in teaching physical chemistry.

    PubMed

    McKenzie, T L; Marshall, S J; Sallis, J F; Conway, T L

    2000-09-01

    There is little research on students' engagement in physical activity in middle school physical education (PE). We observed student activity, lesson context, and teacher behavior in 430 PE lessons taught by 126 teachers in 24 schools. Variables were analyzed by mixed-model nested analyses of covariance. Boys were more active than girls overall and during skill drills, game play, and free play. Student activity varied by lesson context, with fitness activities producing the most activity. Class size was negatively associated with student activity. Daily PE contributed a weekly total of 25 min of vigorous activity and 83 min of moderate-to-vigorous activity--much less than national objectives. Results suggest that numerous opportunities exist for increasing student physical activity during middle school PE.

    atmospheric circulation with applications of the Lorenz model, explored the land-sea breeze problem with the Dynamics and Thermodynamics Circulation Model (DTDM), and developed simple radiative transfer models. Class projects explored the effects of varying the content of CO2 and CH4 in the atmosphere, as well as the properties of paleoclimates in atmospheric simulations using EdGCM. Initial assessment of student knowledge, attitudes, and behaviors associated with these activities, particularly about climate change, was measured. Pre- and post-course surveys provided student perspectives about the courses and their learning about remote sensing and climate change concepts. Student performance on the tutorials and course projects evaluated students' ability to learn and apply their knowledge about climate change and skills with remote sensing to assigned problems or proposed projects of their choice. Survey and performance data illustrated that the exercises were successful in meeting their intended learning objectives as well as opportunities for further refinement and expansion.

    2006-01-01

    Many studies which were published in other countries identified certain benefits and barriers to physical activity among young people. But there is no data about the subject pertaining to Turkish adolescents. This study tries to rectify this with a study of Turkish university students. Undergraduate university students (n = 303) were recruited to the study. Current exercise habits and perceived barriers to physical activity were assessed in the sample. Using a Likert Type scale, participants responded an instrument with 12 items representing barriers to physical activity. Mean scores were computed. External barriers were more important than internal barriers. "Lack of time due to busy lesson schedule", "My parents give academic success priority over exercise. "and "lack of time due to responsibilities related to the family and social environment "were most cited items for physical activity barriers. There is a need for future research, which will be carried out with larger sample groups to develop national standardized instrument. It will be helpful for accurately identify perceived barriers and then recommend changes to enhance physical activity among young people. Key PointsThe purpose of this study was to analyze perceived barriers to physical activity in the university students.The results showed that not having enough time was the most important barrier for not participating in physical activity among our samples.This study with relatively small sample must be considered as pilot study for related studies in the future.

    One of the many services that intelligent systems can provide is the ability to analyze the impact of different medical conditions on daily behavior. In this study, we use smart home and wearable sensors to collect data, while ( n = 84) older adults perform complex activities of daily living. We analyze the data using machine learning techniques and reveal that differences between healthy older adults and adults with Parkinson disease not only exist in their activity patterns, but that these differences can be automatically recognized. Our machine learning classifiers reach an accuracy of 0.97 with an area under the ROC curve value of 0.97 in distinguishing these groups. Our permutation-based testing confirms that the sensor-based differences between these groups are statistically significant.

  6. Analyzing compound activity records and promiscuity degrees in light of publication statistics

    PubMed Central

    Hu, Ye; Bajorath, Jürgen

    2016-01-01

    For the generation of contemporary databases of bioactive compounds, activity information is usually extracted from the scientific literature. However, when activity data are analyzed, source publications are typically no longer taken into consideration. Therefore, compound activity data selected from ChEMBL were traced back to thousands of original publications, activity records including compound, assay, and target information were systematically generated, and their distributions across the literature were determined. In addition, publications were categorized on the basis of activity records. Furthermore, compound promiscuity, defined as the ability of small molecules to specifically interact with multiple target proteins, was analyzed in light of publication statistics, thus adding another layer of information to promiscuity assessment. It was shown that the degree of compound promiscuity was not influenced by increasing numbers of source publications. Rather, most non-promiscuous as well as promiscuous compounds, regardless of their degree of promiscuity, originated from single publications, which emerged as a characteristic feature of the medicinal chemistry literature.

    2005-06-01

    The importance of attitudes toward science has risen from widely accepted assumptions that achievement and attitude are positively interdependent and that affective variables are as important as cognitive variables in molding student learning. This report examines the effect on student attitudes toward learning chemistry in an active learning environment that has incorporated elements believed to positively influence student attitudes toward science including cooperative learning, hands-on activities, real-world applications, and engaging technology. These elements were considered for synergetic effects and not as individual contributors to the overall results. Two different sections of the same general chemistry course participated. The lecture setting was used as the control. Residualized gain scores were used to compare net changes in student attitudes. Data were analyzed for possible differences in gain for different academic majors. Anxiety in chemistry was monitored for the two class settings in three areas, learning in chemistry, chemistry evaluation, and chemical handling. Qualitative student feedback was also collected and is summarized in this report on the attitudinal aspects of instruction.

  13. [Influences of uncommon isoenzymes on determination of alkaline phosphatase activity by dry-chemistry analyzers].

    PubMed

    Tozawa, T; Hashimoto, M

    2001-04-01

    Dry-chemistry(DC) analysis may be influenced by some matrix effects for measuring uncommon isoenzyme forms. Placental and intestinal alkaline phosphatase(AP) are overestimated by the VITROS DC, compared with results obtained with the wet-chemistry(WC) method of Bretaudiere, et al. using 2-amino-2-methyl-1-propanol (AMP) buffer, however, no such discrepancy between AP results in any DC method and that with a routine WC method recommended by Japanese Society of Clinical Chemistry in that 2-ethylaminoethanol(EAE) buffer is used, has been demonstrated. The type of buffer used affects differently the rates of AP isoenzymes activities. We therefore examined whether the presence of uncommon AP isoenzyme forms in serum caused aberrant DC results for AP in comparison with a routine WC method using EAE buffer. Here, serum samples with only liver AP and bone AP(n : 32); high-molecular-mass AP(n : 11); placental AP(n : 12); intestinal AP(n : 13) and immunoglobulin (Ig) bound AP(n : 12) were analyzed for total AP activity on three different DC analyzers: VITROS 700XR, FUJIDRYCHEM 5000, SPOTCHEM 4410 and a WC analyzer: HITACHI 7350. Values obtained in all of the DCs for sera containing only liver/bone AP agreed with those with the WC method. For sera containing placental AP, the VITROS values were higher than those with the WC method, while the FUJIDRYCHEM values and the SPOTCHEM values were lower. The VITROS values and the FUJIDRYCHEM values for sera containing intestinal AP were lower than those with the WC method, while the SPOTCHEM values were higher. All of the DCs did not affect high-molecular-mass AP and Ig bound liver/bone AP types of macro AP, but underestimated Ig bound intestinal type. Ig bound intestinal AP may be sieved by DC multilayer elements. PMID:11391954

    2005-01-01

    Background A number of algorithms for steady state analysis of metabolic networks have been developed over the years. Of these, Elementary Mode Analysis (EMA) has proven especially useful. Despite its low user-friendliness, METATOOL as a reliable high-performance implementation of the algorithm has been the instrument of choice up to now. As reported here, the analysis of metabolic networks has been improved by an editor and analyzer of metabolic flux modes. Analysis routines for expression levels and the most central, well connected metabolites and their metabolic connections are of particular interest. Results YANA features a platform-independent, dedicated toolbox for metabolic networks with a graphical user interface to calculate (integrating METATOOL), edit (including support for the SBML format), visualize, centralize, and compare elementary flux modes. Further, YANA calculates expected flux distributions for a given Elementary Mode (EM) activity pattern and vice versa. Moreover, a dissection algorithm, a centralization algorithm, and an average diameter routine can be used to simplify and analyze complex networks. Proteomics or gene expression data give a rough indication of some individual enzyme activities, whereas the complete flux distribution in the network is often not known. As such data are noisy, YANA features a fast evolutionary algorithm (EA) for the prediction of EM activities with minimum error, including alerts for inconsistent experimental data. We offer the possibility to include further known constraints (e.g. growth constraints) in the EA calculation process. The redox metabolism around glutathione reductase serves as an illustration example. All software and documentation are available for download at . Conclusion A graphical toolbox and an editor for METATOOL as well as a series of additional routines for metabolic network analyses constitute a new user-friendly software for such efforts.

    Ruhf, Robert James

    This study tested whether or not pre-service teacher education students enrolled in inquiry-based earth science courses gained more thorough knowledge, comprehension, and application proficiencies with regard to atmospheric science concepts included in the Michigan Curriculum Framework for Science Education---the content standards of the Michigan State Board of Education for K-12---than did pre-service teacher education students enrolled in a traditionally-based earth science lecture/laboratory course. Content proficiencies were tested at the beginning of the semester (the pretest) and again at the end of the semester (the posttest). A sample of students participated in post-test interview sessions designed to examine in depth their knowledge, comprehension, and application proficiencies with regard to atmospheric science content. Classroom observation data related to the behavior of both students and instructors were collected and were later coded and analyzed using a lesson observation instrument that was based on Michigan and national teaching and learning standards and had an orientation toward inquiry and investigative approaches to learning. Analysis of the pretest/posttests revealed that students in the traditional course demonstrated gains in knowledge and comprehension of content that resulted in statistically significant improvements on the overall posttest scores. Students in the inquiry-based courses accomplished some improvements in knowledge, comprehension and application proficiencies that did not result in statistically significant improvements on the overall posttest scores. The analysis of data suggests that the traditional course was more effective in preparing pre-service teachers to teach content consistent with the Michigan Curriculum Framework. The interpretation of the classroom observations and the interview sessions revealed that the inquiry-based courses were not fully consistent with national and state standards, included activities that

    Many Latinos are insufficiently active, partly due to neighborhoods with little environmental support for physical activity. Multi-level approaches are needed to create health-promoting neighborhoods in disadvantaged communities. Participant "citizen scientists" were adolescent (n = 10, mean age = 12.8 ± 0.6 years) and older adult (n = 10, mean age = 71.3 ± 6.5 years), low income Latinos in North Fair Oaks, California. Citizen scientists conducted environmental assessments to document perceived barriers to active living using the Stanford Healthy Neighborhood Discovery Tool, which records GPS-tracked walking routes, photographs, audio narratives, and survey responses. Using a community-engaged approach, citizen scientists subsequently attended a community meeting to engage in advocacy training, review assessment data, prioritize issues to address and brainstorm potential solutions and partners. Citizen scientists each conducted a neighborhood environmental assessment and recorded 366 photographs and audio narratives. Adolescents (n = 4), older adults (n = 7) and community members (n = 4) collectively identified reducing trash and improving personal safety and sidewalk quality as the priority issues to address. Three adolescent and four older adult citizen scientists volunteered to present study findings to key stakeholders. This study demonstrated that with minimal training, low-income, Latino adolescent and older adult citizen scientists can: (1) use innovative technology to gather information about features of their neighborhood environment that influence active living, (2) analyze their information and identify potential solutions, and (3) engage with stakeholders to advocate for the development of healthier neighborhoods.

    2010-01-01

    The researchers surveyed nursing students yearly during their three-year education, and examined active and emotional engagement. We examined the association of these properties with seven independent variables: higher educational institution, class size, age, gender, prior assistant nurse education, study experience and self-rated health. This longitudinal study included 1,334 students from 24 universities and university colleges in Sweden. Active engagement increased and emotional engagement decreased during the study years. Male students, older students and those with prior assistant nurse education had higher active engagement than other students. Older students, females, students with good self-rated health and those attending universities had higher emotional engagement. Study results suggest that higher educational institutions should pay more attention to students' active and emotional engagement in learning situations, since this may increase the ability of the students to cope with stressful events during their education, giving them an extra resource on which they can draw.

  9. Hilbert–Huang transform in detecting and analyzing the uterine contraction activities

    Aydın, Kemal; Demirer, Murat; Bayrak, Coşkun

    2015-01-01

    Objective The diagnosis of labor is currently one of the most difficult problems encountered by obstetrical healthcare providers. A major health problem is the increase in the rate of preterm delivery, which is responsible for 75% of all deaths in newborns. In addition, preterm delivery is associated with several cognitive and health problems in later life and enormous costs for the health system. A better understanding of myometrial activities could help to reduce preterm deliveries and the costs associated with prematurity in the following years. Therefore, the objective of this study was to determine whether using the Hilbert–Huang transform (HHT) to analyze the uterine contraction data would help us gain a better insight of the myometrial activities of the human uterus during pregnancy. Material and Methods Uterine magnetomyographic (MMG) signals were recorded from pregnant patients at gestational ages of 32–38 weeks. The study was approved by the Human Research Advisory Board of the University of Arkansas for Medical Sciences (UAMS) and performed after obtaining written consent from each patient. The recording of transabdominal MMG signals was conducted with the SQUID Array for Reproductive Assessment (SARA, VSM MedTech Inc; Coquitlam, BC, Canada) system, which has 151 primary magnetic sensors allocated approximately 3 cm apart over an area of 850 cm2. The arrangement of sensors is concave in nature and, in a similar lateral distance, spans the maternal abdomen longitudinally from the symphysis pubis to the uterine fundus. The recording times ranged from 12 to 28 min, and the sampling rate was 250 Hz. The data were down-sampled to 25 Hz to reduce the computational complexity and post-processed with a bandpass filter (0.05–1 Hz) because the uterine contraction activity is a band-limited process (0.05–1 Hz). The recordings of one intrauterine pressure catheter (IUPC) dataset and two mother-perceived contraction datasets were compared with the HHT results

    2014-01-01

    Video tracking systems have been used widely to analyze Drosophila melanogaster movement and detect various abnormalities in locomotive behavior. While these systems can provide a wealth of behavioral information, the cost and complexity of these systems can be prohibitive for many labs. We have developed a low-cost assay for measuring locomotive behavior and seizure movement in D. melanogaster. The system uses a web-cam to capture images that can be processed using a combination of inexpensive and free software to track the distance moved, the average velocity of movement and the duration of movement during a specified time-span. To demonstrate the utility of this system, we examined a group of D. melanogaster mutants, the Bang-sensitive (BS) paralytics, which are 3-10 times more susceptible to seizure-like activity (SLA) than wild type flies. Using this novel system, we were able to detect that the BS mutant bang senseless (bss) exhibits lower levels of exploratory locomotion in a novel environment than wild type flies. In addition, the system was used to identify that the drug metformin, which is commonly used to treat type II diabetes, reduces the intensity of SLA in the BS mutants. PMID:24637378

  13. A bispectral approach to analyze nonlinear cochlear active mechanisms in transient evoked otoacoustic emissions.

    PubMed

    Marchesi, Stefano; Tognola, Gabriella; Paglialonga, Alessia

    2013-08-01

    A new approach to study nonlinearity in cochlear active mechanisms, as evaluated in transient evoked otoacoustic emissions (TEOAEs), is presented. TEOAEs are signals generated in the cochlea by a mix of linear and nonlinear mechanisms. This new approach was designed to complement the traditional TEOAE analysis performed by currently available systems used in objective hearing screening and assessment. Nonlinearity of TEOAEs was studied by means of the bispectrum, which is able to find out quadratic frequency couplings (QFCs) that occur when a frequency is not only generated by an independent cochlear source, but it is the result of the interaction among a number of cochlear sources. To fit with the technical constraints of currently available TEOAE systems, the bispectrum was estimated by the third-order scaled polyperiodogram. The proposed method was characterized with synthesized TEOAEs as a function of the main TEOAE parameters and then used to analyze TEOAEs recorded in normal hearing adults and full-term neonates. Results revealed the presence of QFCs in both adult and neonatal TEOAEs, with peculiar patterns and significantly different frequency content in the two groups: adults had QFCs mainly around 2 kHz and neonates had QFCs mainly in the range 3.5-4 kHz.

  19. Revalidation of the Volatile Organic Analyzer Following a Major On-Orbit Maintenance Activity

    NASA Technical Reports Server (NTRS)

    Limero, Thomas; James, John T.

    2007-01-01

    The Volatile Organic Analyzer (VOA) contributes to the assessment of air quality aboard the International Space Station (ISS) by identifying and quantifying target airborne volatile organic contaminants in the module air. This on-orbit contaminant monitoring capability becomes particularly important during an air quality degradation event such as a system leak. During several ISS air quality degradations, the VOA has generated near real-time data that was used to make decisions or to better understand the contingency. The VOA was operational from January 2002 through June 2003, during which time it was validated by comparing VOA data to simultaneously acquired grab sample containers (GSCs). In January 2003, one of the two analytical channels of the VOA was shutdown because of a component failure, but a redundant channel continued to supply the necessary analytical data. In June 2003, the sole remaining channel was deactivated. Initial assessments of the channel shutdowns pointed to failed fuses or heaters, but neither was considered repairable on orbit. In 2005, it was determined that failed fuses could be replaced on orbit and the crew conducted a diagnostic procedure to identify the failed component. The crew discovered that both channels incurred failed fuses, which lead to a subsequent on orbit maintenance activity and return of the VOA to operational status in December 2005. The VOA has been providing data on the ISS atmosphere since its reactivation in 2005 and this paper will present the VOA data collected during 2006. Special emphasis will be placed upon the revalidation of the repaired VOA using GSCs as well as a summary of the diagnostic and repair procedures.

    2015-08-01

    Process diagrams describe how a system functions (e.g. photosynthesis) and are an important type of representation in Biology education. In the present study, we examined students' learning activities while studying process diagrams, related to their resulting comprehension of these diagrams. Each student completed three learning tasks. Verbal data and eye-tracking data were collected as indications of students' learning activities. For the verbal data, we applied a fine-grained coding scheme to optimally describe students' learning activities. For the eye-tracking data, we used fixation time and transitions between areas of interest in the process diagrams as indices of learning activities. Various learning activities while studying process diagrams were found that distinguished between more and less successful students. Results showed that between-student variance in comprehension score was highly predicted by meaning making of the process arrows (80%) and fixation time in the main area (65%). Students employed successful learning activities consistently across learning tasks. Furthermore, compared to unsuccessful students, successful students used a more coherent approach of interrelated learning activities for comprehending process diagrams.

    2009-05-01

    Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and women. The practice of physical activity has also a direct effect on future intention to practice. Likewise, the participation in sport competitions predicts practice of physical activity and future intention in men, whereas being a member of a sports club predicts practice and future intention in women.

    NASA Astrophysics Data System (ADS)

    Erickson, Sabrina Ann

    Preparing students for success in the 21st century has shifted the focus of science education from acquiring information and knowledge to mastery of critical thinking and problem-solving skills. The purpose of this qualitative case study was to examine teacher and student perspectives of the relationship between (a) active learning, problem solving, and achievement in science and (b) the conditions that help facilitate this environment. Adapting a social constructivist theoretical framework, high school science teachers and students were interviewed, school records analyzed, curriculum documents studied, and classes observed. The findings revealed that students were engaged with the material in an active learning environment, which led to a sense of involvement, interest, and meaningful learning. Students felt empowered to take ownership of their learning, developed the critical thinking skills necessary to solve problems independently and became aware of how they learn best, which students reported as interactive learning. Moreover, student reflections revealed that an active environment contributed to deeper understanding and higher skills through interaction and discussion, including questioning, explaining, arguing, and contemplating scientific concepts with their peers. Recommendations are for science teachers to provide opportunities for students to work actively, collaborate in groups, and discuss their ideas to develop the necessary skills for achievement and for administrators to facilitate the conditions needed for active learning to occur.

    2012-06-01

    To achieve the goal of scientific literacy, the skills of argumentation have been emphasized in science education during the past decades. But the extent to which students can apply scientific knowledge to their argumentation is still unclear. The purpose of this study was to analyse 80 Swedish upper secondary students' informal argumentation on four socioscientific issues (SSIs) to explore students' use of supporting reasons and to what extent students used scientific knowledge in their arguments. Eighty upper secondary students were asked to express their opinions on one SSI topic they chose through written reports. The four SSIs in this study include global warming, genetically modified organisms (GMO), nuclear power, and consumption. To analyse students' supporting reasons from a holistic view, we used the SEE-SEP model, which links the six subject areas of sociology/culture (So), environment (En), economy (Ec), science (Sc), ethics/morality (Et) and policy (Po) connecting with three aspects, knowledge, value and personal experience (KVP). The results showed that students used value to a greater extent (67%) than they did scientific knowledge (27%) for all four SSI topics. According to the SEE-SEP model, the distribution of supporting reasons generated by students differed among the SSI topics. Also, some alternative concepts were disclosed in students' arguments. The implications for research and education are discussed.

    Although numerous methods for the determination of HIV protease (HIV-PR) activity have been described, new high-throughput assays are required for clinical and pharmaceutical applications due to the occurrence of resistant strains. In this study, a simple enzymatic immunoassay to identify HIV-PR activity was developed based on a Ni(2+)-immobilized His(6)-Matrix-Capsid substrate (H(6)MA-CA) is cleaved by HIV protease-His(6) (HIV-PRH(6)) which removes the CA domain and exposes the free C terminus of MA. Following this cleavage, two monoclonal antibodies specific for either the free C-terminal MA or CA epitope are used to quantify the proteolytic activity using a standard ELISA-based system. Specificity for detection of the HIV-PRH(6) activity was confirmed with addition of protease inhibitor (PI), lopinavir. In addition, the assay was able to detect an HIV-PR variant activity indicating that this assay is capable of assessing viral mutation affect HIV-PR activity. The efficacy of commercially available PIs and their 50% inhibitory concentration (IC(50)) were determined. This assay provides a high-throughput method for both validating the efficiency of new drugs in vitro and facilitating the discovery of new PIs. In addition, it could serve as a method for examining the influence of various mutations in HIV-PRs isolated from drug-resistant strains.

    The purpose of this study was to analyze motivational profiles based on the self-determination theory (Deci and Ryan, 2000) and how these profiles are related to physical education students' enjoyment, state anxiety, and physical activity. The participants, 429 sixth grade students (girls = 216; boys = 213) completed SMS, Sport Enjoyment Scale, PESAS, and Physical Activity Scale. Cluster analyses identified two motivational profiles: 1) the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2) the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation. The students in the first cluster enjoyed physical education more and were physically more active. The results revealed that students may be motivated towards physical education lessons both intrinsically and extrinsically, and still experience enjoyment in physical education. Key pointsTWO MOTIVATIONAL PROFILES WERE REVEALED: 1) the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2) the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation.The students in the first profile enjoyed physical education more and were physically more active than the students in the second profile.Moreover, the representatives of the "High motivation profile "experienced greater anxiety toward physical education than the representatives of the "Low motivation profile"These findings raised an interesting question whether students engaging in physical education benefit more from the presence of both self-determined and non-self-determined forms of motivation, or are the benefits higher if students are primarily self-determined?

  10. Preparing students to participate in an active learning environment.

    1996-06-01

    Most students have spent the majority of their school career in passive learning environments in which faculty were disseminators of information, and students were required to memorize information or use specified algorithms to "solve problems." In an active learning environment, students are encouraged to engage in the process of building and testing their own mental models from information that they are acquiring. In such a learner-centered environment, faculty become facilitators of learning, and students become active participants, engaging in a dialogue with their colleagues and with the instructor. To create a successful active learning environment, both faculty and students must make adjustments to what has been their respective "traditional" roles in the classroom. For the instructor who is committed to promoting active learning, the challenge lies in helping students understand the necessity of becoming active colleagues in learning. This process can be facilitated if the curriculum includes exercises to direct students' attention to a number of issues that impact their learning. This paper describes four such exercises designed to help students form appropriate course expectations, recognize the need for seeking clarification when communicating, recognize the role of personal experience in building mental models, and become familiar with study aids for building formal models.

  11. Simultaneous blind separation and clustering of coactivated EEG/MEG sources for analyzing spontaneous brain activity.

    2014-01-01

    Analysis of the dynamics (non-stationarity) of functional connectivity patterns has recently received a lot of attention in the neuroimaging community. Most analysis has been using functional magnetic resonance imaging (fMRI), partly due to the inherent technical complexity of the electro- or magnetoencephalography (EEG/MEG) signals, but EEG/MEG holds great promise in analyzing fast changes in connectivity. Here, we propose a method for dynamic connectivity analysis of EEG/MEG, combining blind source separation with dynamic connectivity analysis in a single probabilistic model. Blind source separation is extremely useful for interpretation of the connectivity changes, and also enables rejection of artifacts. Dynamic connectivity analysis is performed by clustering the coactivation patterns of separated sources by modeling their variances. Experiments on resting-state EEG show that the obtained clusters correlate with physiologically meaningful quantities. PMID:25571098

    1993-06-01

    Previous work has established the precision and accuracy of a portable blood coagulation analysis system using paramagnetic particles contained in a dry reagent on a disposable test card. We examined the deployment of this technology in decentralized hospital settings and compared test results obtained in the surgical intensive care unit, coronary care unit, and outpatient cardiology clinic with those obtained in the central laboratory. Nursing personnel were instructed in the use of the system, and quality control testing was performed daily by the laboratory staff. In the intensive care units, patient subjects included those on whom tests of prothrombin time and activated partial thromboplastin time had been ordered. Immediate determinations were performed by the intensive care unit nursing staff on the same citrated, whole-blood samples that were subsequently sent to the central laboratory. In the outpatient cardiology clinic, fingerstick blood samples were obtained for prothrombin time determinations with the dry chemistry system. Paired prothrombin time samples obtained by venipuncture were run in the hospital laboratory. The study involved multiple users, multiple locations, two lots of activated partial thromboplastin time cards, and several different instruments, over an extended period. Correlation coefficients between the dry chemistry system and the hospital laboratory under these conditions were in an acceptable range in all sites studied. We concluded that, with appropriate training and quality assurance, the dry chemistry system provides an acceptable alternative to the hospital laboratory for prothrombin time and activated partial thromboplastin time determinations.

  16. Stability of the Tilt Modes of an Actively Controlled Flywheel Analyzed

    Brown, Gerald V.; Kascak, Albert F.

    1999-01-01

    Applications of strongly gyroscopic rotors are becoming important, including flywheels for terrestrial and space energy storage and various attitude control devices for spacecraft. Some of these applications, especially the higher speed ones for energy storage, will have actively controlled magnetic bearings. These bearings will be required where speeds are too high for conventional bearings, where adequate lubrication is undesirable or impossible, or where bearing losses must be minimized for efficient energy storage. Flywheel rotors are highly gyroscopic, and above some speed that depends on the bandwidth of the feedback system, they always become unstable in an actively controlled magnetic bearing system. To assess ways to prevent instability until speeds well above the desired operating range, researchers at the NASA Lewis Research Center used a commercial controls code to calculate the eigenvalues of the tilt modes of a rigid gyroscopic rotor supported by active magnetic bearings. The real part of the eigenvalue is the negative of the damping of the mode, and the imaginary part is approximately equal to the mode s frequency.

    2009-12-01

    Deep subseafloor microbes play significant roles on biogeochemical cycles with extremely low metabolic activities. The subseafloor microbial community consists mainly of uncultured components; hence, their growth and metabolic characteristics remain almost completely unknown. Here, we presnet in vitro isotopic evidence that the deep subseafloor microbes actively incooporate multiple carbon and nitrogen compounds into their biomass using NanoSIMS. We incubated methane hydrate-bearing deep marine sediments with small 13C-labeled glucose, acetate, pyruvate, bicarbonate, amino-acids and methane in the presence of 15N-labeled ammonia as a nitrogen source for 2 and 6 monthes under the anaerobic condition. Using NanoSIMS, we observed the cells that incooprated 13C- or 15N-labeled substrates such as 13C-glucose, pyruvate, and 15N-ammonia up to 50% of their cellular carbon or nitrogen mass. Assimilation of 13C- and 15N-labeled amino acids as well as 13C-bicarbonates by autotrophs was also observed while 13C-methane was found to be difficult to be used for the carbon source, regardless of the presence of some additional electron acceptors for the energy respiration. These results indicate that the metabolic activities of deep subseafloor microbes can be stimulated in vitro by adding potential carbon and nitrogen sources, providing new insights into the biogeochemical functioning of the deep subseaflor microbes and its ecosystem.

    1993-01-01

    Higher activity of the NAD-dependent dehydrogenases of the tricarboxylic acid cycle (TAC) is observed in the optic retina, and of FAD-dependent dehydrogenases in the occipital lobes of the brain, in the visual analyzer of intact rats. The influence of stress using Desiderato's method induces a compensatory increase in the activity of succinate dehydrogenase. Acute stress induces a change in the regulation of the activity of the TAC dehydrogenases, assessed on the basis of the reaction to functional load. The animals' remaining in the dark following stress promotes the restoration of the activity of the TAC cycle to the normal level. PMID:8413911

    The ability to read, interpret, and evaluate articles in the primary literature are important skills that science majors will use in graduate school and professional life. Because of this, it is important that students are not only exposed to the primary literature in undergraduate education, but also taught how to read and interpret these articles. To achieve this objective, POGIL activities were designed to use the primary literature in a majors biochemistry sequence. Data show that students were able to learn content from the literature without separate activities or lecture. Students also reported an increase in comfort and confidence in approaching the literature as a result of the activities.

    This study examined the hypothesis that when students received and/or provided either support for skill improvement or support for interpersonal relations, their overall adjustment level in extracurricular activities would be higher than for students who received and/or provided neither support. Data were analyzed from 475 junior high school students (female 175, male 300) who were taking extracurricular sports activities, out of 743 research participants. The results were as follows. Students who received support mainly for skill improvement showed a statistically equivalent adjustment level as students who received support mainly for interpersonal relations. Students who received either support showed higher adjustment levels than students who received neither. Additionally, providing support showed the same results. The exchange of different types of social support showed equivalent effects on the adjustment level as the exchange of the same type of social support. These results suggest that even though the types of social support are different for skill improvement or interpersonal relations, the exchange of support positively contributes to junior high school students' adjustment level in extracurricular activities.

    2007-01-01

    High-resolution functional magnetic resonance imaging (hi-res fMRI) promises to help bridge the gap between the macro- and the microview of brain function afforded by conventional neuroimaging and invasive cell recording, respectively. Hi-res fMRI (voxel volume ≤ (2 mm)3) is robustly achievable in human studies today using widely available clinical 3-Tesla scanners. However, the neuroscientific exploitation of the greater spatial detail poses four challenges: (1) Hi-res fMRI may give inaccurate (i.e. blurred, displaced and distorted) images of fine-scale neuronal activity patterns. (2) Single small voxels yield very noisy measurements. (3) The greater number of voxels complicates interpretation and poses a more severe multiple-comparisons problem. (4) The functional correspondency mapping between individual brains is unknown at the fine scale of millimeters. Here we argue that these challenges can be met by shifting the focus of brain mapping and visualizing, not the activity patterns themselves, but the amount of information they convey about the experimental conditions.

  20. Attachment relationships and physical activity motivation of college students.

    PubMed

    Ullrich-French, Sarah; Smith, Alan L; Cox, Anne E

    2011-08-01

    This study was designed to assess the link of attachment relationships with physical activity motivation. Potential mediators of this link were examined in a cross-sectional study targeting college student physical activity motivation and behaviour. Participants completed self-reports of attachment relationships (with mother, father and best friend), self-determined motivation for physical activity, physical activity behaviour and the hypothesised mediator variables of perceived competence, autonomy and relatedness. The results provide support for the mediating role of these variables in the association of father attachment with self-determined motivation. Meaningful variance in self-determined motivation for physical activity and physical activity behaviour was explained. Overall, attachment relationships appear to be relevant, albeit modestly, to physical activity motivation of college students. The findings support continued efforts to integrate attachment and motivational perspectives in the study of college student health behaviour.

  1. Ce-PROMOTED Bond Activation of Propene Probed by Mass-Analyzed Threshold Ionization Spectroscopy

    NASA Astrophysics Data System (ADS)

    Zhang, Yuchen; Kumari, Sudesh; Yang, Dong-Sheng

    2016-06-01

    The reaction of Ce + propene (CH2=CH-CH3) was carried out in a laser-ablation supersonic molecular beam source. CeC_2H_2, CeC_3H_4, CeC_3H_6, CeC_4H_6, CeC_6H10, and CeC_6H12 were identified by photoionization time-of-flight mass spectrometric measurements, and their structures and electronic states were investigated with mass-analyzed threshold ionization (MATI) spectroscopy and theoretical calculations. The metal complexes containing two or three carbon atoms were formed by the C-C bond breakage (CeC_2H_2), dehydrogenation (CeC_3H_4), or metal insertion into a C-H bond (CeC_3H_6) of a propene molecule. The larger complexes with four to six carbons are formed through secondary reactions involving C-C bond coupling and dehydrogenation. The ground electronic states of the neutral CeC_2H_2, CeC_3H_4, CeC_3H_6, and CeC_4H_6 complexes are triplets with a 4f16s1 electron configuration on the Ce center, and those of the corresponding ions are doublet with a 4f1 configuration. Their MATI spectra are much more complex than those of the corresponding La species formed in the La + propene reaction previously observed by our group. The spectral complexity arises from possibly multiple electronic transitions due to the existence of a 4f electron of the Ce atom which could be located in any one of the seven f-atomic orbitals or involved in considerable spin-orbit interactions.

  2. An Activation Force-based Affinity Measure for Analyzing Complex Networks

    PubMed Central

    Guo, Jun; Guo, Hanliang; Wang, Zhanyi

    2011-01-01

    Affinity measure is a key factor that determines the quality of the analysis of a complex network. Here, we introduce a type of statistics, activation forces, to weight the links of a complex network and thereby develop a desired affinity measure. We show that the approach is superior in facilitating the analysis through experiments on a large-scale word network and a protein-protein interaction (PPI) network consisting of ∼5,000 human proteins. The experiment on the word network verifies that the measured word affinities are highly consistent with human knowledge. Further, the experiment on the PPI network verifies the measure and presents a general method for the identification of functionally similar proteins based on PPIs. Most strikingly, we find an affinity network that compactly connects the cancer-associated proteins to each other, which may reveal novel information for cancer study; this includes likely protein interactions and key proteins in cancer-related signal transduction pathways.

    Salvage-Jones, Judith; Hamill, Jessie; Todorovic, Michael; Barton, Matthew J; Johnston, Amy N B

    2016-07-01

    Effective engagement of nursing students in the study of biosciences remains a challenge for many tertiary institutes. In this study we attempted to implement and then evaluate a simple hands-on intervention, consisting of a series of hands-on games and puzzles, to increase nursing student engagement with core concepts and anatomical learning involved in clinical anatomy and physiology. The study used a quazi-experimental longitudinal before and after design, to explore the effect of a learning intervention on student performance. Set across three different campuses of the same University, it included 1320 first year undergraduate nursing students from 2013 to 2014 who were studying Anatomy and Physiology. Students were exposed to the interventions or not, and concomitant academic performance, weekly quiz scores, performance in fortnightly worksheets and, across the semester, exam performance were compared. The results show that while the intervention appeared to increase academic performance in students on one campus (2013) compared to the other two, this difference was not sustained into 2014 when a bigger cohort was examined. Despite significant subjective student satisfaction and enthusiasm about these learning and teaching interventions, the data does not support the capacity of these activities to enhance student academic performance. Tertiary entrance scores, being a non-native English speakers and socio-economic status all had a bigger impact on student performance than engagement with fun anatomy and physiology activities.

    Graduate nursing faculty evaluated their initial experiences with online course discussions after making the transition from traditional use of weekly face-to-face classroom discussions to primarily computer-based interactions with students at distant sites. The online discussion data were analyzed qualitatively. The ways the faculty member communicated to facilitate active student involvement in the online discussions were coded. Six categories were identified that describe the ways the faculty member communicated to facilitate active student involvement in online discussions: assist with navigation, explain expectations, clarify faculty role, stimulate critical thinking, share expertise, and provide encouragement. Examples of each were provided to demonstrate ways faculty promoted student learning in online discussions. PMID:10939187

    This reports a history and future prospects of the activities by the Student Forum of the Geoinformation Forum Japan. For growths of academic fields, active communications among students and young scientists are indispensable. Several academic communities in geoinformation fields are established by youths and play important roles of building networks over schools and institutes. The networks are expected to be innovative cooperation after the youths achieve their professions. Although academic communities are getting fixed growth particularly in Japan, youths had gotten little opportunities to make contacts with youths themselves. To promote gotten youth activities among geoinformation fields, in 1998, we started a series of programs that named the Student Forum of the Geoinformation Forum Japan involving students and young scientists within the annual conferences, Geoinformation Forum Japan. The programs have provided opportunities to do presentation their studies by posters, some events, and motivations to create networks among students and young scientists. From 2009, some members of our activities set additional conference in west area of Japan. Thus our activities are spread within Japan. As a result of these achievements, the number of youth dedicating to the programs keeps growing. From 2009, it's getting international gradually, however, almost all the participants are still Japanese. To keep and expand the network, we are planning to make some nodes with some Asian youth organizations in the field of geoinformation. This paper is concluded with proposals and future prospects on the Student Forum of the Geoinformation Forum Japan.

Our assessment included examining student conceptual understanding before and after studying electromagnetism in a media-rich environment. We developed pre-and posttests consisting of conceptual questions from standardized tests, as well as questions designed to assess the effect of visualizations and experiments. The research population consisted of 811 undergraduate students, consisting of small-and a large-scale experimental group and control group. The active learning students improved their conceptual understanding of the subject matter to a significantly higher extent than their control group peers. A subsequent longitudinal study indicates that the long-term effect of the TEAL course on student retention of concepts was significantly stronger than that of the traditional course.

    Optics and photonics research in Africa has gradually grown in the past ten years with a very active optical community involved in state-of-the-art research. Despite relatively low resources, optics research in the continent is competitive with many international benchmarks and has had a significant impact within the African continent. In the past five years, a group of dynamic students have developed the student chapter network from Tunisia to South Africa. The first student chapters of the optical society of America (OSA) and the international society for optics and photonics (SPIE) were established in South Africa (in the Council for Scientific and Industrial Research (CSIR) and in the University of Stellenbosch), followed by a chapter in Tunisia (Engineering school of communications of Tunis, Sup'Com). In this paper, we will present the major activities of the student chapters of Tunisia and South Africa, and how they are promoting optics and photonics in Africa.

  14. MDC-Analyzer-facilitated combinatorial strategy for improving the activity and stability of halohydrin dehalogenase from Agrobacterium radiobacter AD1.

    Halohydrin dehalogenase from Agrobacterium radiobacter AD1 (HheC) displays a broad substrate range with high regio- and enantioselectivity of both ring-closure and ring-opening reactions, making the enzyme a useful catalyst for the production of optically pure epoxides and β-substituted alcohols. In this study, we report a novel method using an MDC-Analyzer-facilitated combinatorial strategy to improve the activity and stability of HheC by simultaneously randomizing multiple contiguous residues. Six contiguous active-site residues, which are the hotspots for improving the activity of HheC, were simultaneously selected and randomized using the MDC-Analyzer-facilitated combinatorial strategy, resulting in a high-quality mutagenesis library. After screening a total of 1152 clones, three positive mutants were obtained, which exhibited approximately 3.5-5.9-fold higher kcat values than the wild-type HheC toward 1,3-dichloro-2-propanol (1,3-DCP). However, the inactivation half-life of the best mutant (DG9) at 55 °C decreased 9-fold compared with that of the wild-type HheC. To improve the stability of mutant DG9, seven contiguous potential surface amino acids were revealed by using the B-FITTER tool. Two charged amino acids, Glu and Lys, which are more abundant in thermophilic proteins than in their mesophilic counterparts, were selected to substitute those seven amino acids and were combined together via an MDC-Analyzer-facilitated combinatorial strategy. Two mutants displaying 1.6- and 2.3-fold higher half-life τ1/2 (55 °C) values than their DG9 template were obtained after screening only 384 clones. The results indicated that an MDC-Analyzer-facilitated combinatorial strategy represents an efficient tool for the directed evolution of functional enzymes with multiple contiguous targeting sites.

    Objective. To evaluate the impact on pharmacy students of a communication course, which used role-playing to develop active-learning skills. Design. Students role-playing pharmacists in patient care scenarios were critiqued by students and pharmacist faculty members. Grading was performed using the rubric inspired by Bruce Berger’s Communication Skills for Pharmacists. Written skills were evaluated using student written critique questionnaires. Students completed precourse and postcourse self-assessment surveys. Preceptor evaluations were analyzed for course impact. Assessment. Students demonstrated improvement in oral skills based on role-play scores (45.87/50) after practice sessions. The average score based on the student questionnaire was 9.31/10. Gain was demonstrated in all defined course objectives. Impact on introductory pharmacy practice experience (IPPE) communication objectives was insignificant. Student evaluations for course and teaching strategy reflected a high average. Conclusion. Study results demonstrated improvement in oral and written communication skills that may help improve interprofessional teamwork between pharmacists and other health care providers. PMID:25995519

  16. Convenient method of simultaneously analyzing aluminum and magnesium in pharmaceutical dosage forms using californium-252 thermal neutron activation

    A commercial antacid suspension containing aluminum hydroxide and magnesium hydroxide products was used as a model sample to study the use of a californium-252 thermal neutron activation as a method for quantifying aluminum content as well as for the simultaneous assay of aluminum and magnesium. A 3.5-micrograms californium-252 source was used for the activation, and the induced aluminum-28 and magnesium-27 activity was simultaneously measured by sodium iodide crystal gamma-ray spectrometry using dual single-channel analyzers and scalers. The antacid suspension was contained in a chamber designed with the unique capability of serving as the container for counting the induced radioactivity in addition to being the irradiation chamber itself. This pilot study demonstrated that use of more intense californium-252 sources, which are commonly available, would provide a method that is competitive with the ethylenediaminetetraacetic acid titration method in precision and in other aspects as well.

  17. How does participation in inquiry-based activities influence gifted students' higher order thinking?

    NASA Astrophysics Data System (ADS)

    Reger, Barbara H.

    Inquiry-based learning is considered a useful technique to strengthen the critical thinking skills of students. The National Science Standards emphasize its use and the complexities and challenge it provides are well suited for meeting the needs of the gifted. While many studies have documented the effectiveness of this type of instruction, there is a lack of research on growth in higher-order thinking through participation in science inquiry. This study investigated such growth among a small group of gifted fifth-grade students. In this study a group of fifth-grade gifted science students completed a series of three forensics inquiry lessons, and documented questions, ideas and reflections as they constructed evidence to solve a crime. From this class of students, one small group was purposely selected to serve as the focus of the study. Using qualitative techniques, the questions and statements students made as they interacted in the activity were analyzed. Videotaped comments and student logs were coded for emerging patterns and also examined for evidence of increased levels of higher-order thinking based on a rubric that was designed using the six levels of Bloom's Taxonomy. Evidence from this study showed marked increase in and deeper levels of higher-order thinking for two of the students. The other boy and girl showed progress using the inquiry activities, but it was not as evident. The social dynamics of the group seemed to hinder one girl's participation during some of the activities. The social interactions played a role in strengthening the exchange of ideas and thinking skills for the others. The teacher had a tremendous influence over the production of higher-level statements by modeling that level of thinking as she questioned the students. Through her practice of answering a question with a question, she gradually solicited more analytical thinking from her students.

  18. Describing Changes in Undergraduate Students' Preconceptions of Research Activities

    Cartrette, David P.; Melroe-Lehrman, Bethany M.

    2012-12-01

    Research has shown that students bring naïve scientific conceptions to learning situations which are often incongruous with accepted scientific explanations. These preconceptions are frequently determined to be misconceptions; consequentially instructors spend time to remedy these beliefs and bring students' understanding of scientific concepts to acceptable levels. It is reasonable to assume that students also maintain preconceptions about the processes of authentic scientific research and its associated activities. This study describes the most commonly held preconceptions of authentic research activities among students with little or no previous research experience. Seventeen undergraduate science majors who participated in a ten week research program discussed, at various times during the program, their preconceptions of research and how these ideas changed as a result of direct participation in authentic research activities. The preconceptions included the belief that authentic research is a solitary activity which most closely resembles the type of activity associated with laboratory courses in the undergraduate curriculum. Participants' views showed slight maturation over the research program; they came to understand that authentic research is a detail-oriented activity which is rarely successfully completed alone. These findings and their implications for the teaching and research communities are discussed in the article.

    The automated laboratory analyzer COAGTRON-350 (Trinity Biotech) is used for routine and specific coagulation testing for the detection of fibrin formation utilizing either mechanical principles (ball method) or photo-optical principles, chromogenic kinetic enzyme analysis, and immune-turbidimetric detection systems in one benchtop unit. In this study, we demonstrated and established a parameter for the measurement of factor XIII (FXIII) activity using Berichrom FXIII reagent and the COAGTRON-350 analyzer. The usual protocol used for this reagent, based on the handling method, was slightly modified for this device. The analysis showed that fundamental study for the measurement of FXIII activity under our condition setting was favorable in terms of reproducibility, linearity, and correlation with another assays. Since FXIII is the key enzyme that plays important roles in hemostasis by stabilizing fibrin formation, the measurement of FXIII is essential for the diagnosis of bleeding disorders. Therefore, FXIII activity assessment as well as a routine coagulation testing can be conducted simultaneously with one instrument, which is useful in coagulopathy assessment.

  20. Negotiated meanings of disability simulations in an adapted physical activity course: learning from student reflections.

    2014-04-01

    Disability simulations have been used as a pedagogical tool to simulate the functional and cultural experiences of disability. Despite their widespread application, disagreement about their ethical use, value, and efficacy persists. The purpose of this study was to understand how postsecondary kinesiology students experienced participation in disability simulations. An interpretative phenomenological approach guided the study's collection of journal entries and clarifying one-on-one interviews with four female undergraduate students enrolled in a required adapted physical activity course. The data were analyzed thematically and interpreted using the conceptual framework of situated learning. Three themes transpired: unnerving visibility, negotiating environments differently, and tomorrow I'll be fine. The students described emotional responses to the use of wheelchairs as disability artifacts, developed awareness of environmental barriers to culturally and socially normative activities, and moderated their discomfort with the knowledge they could end the simulation at any time.

  1. The evolutionary conformation from traditional lecture to active learning in an undergraduate biology course and its effects on student achievement

    NASA Astrophysics Data System (ADS)

    Diederich, Kirsten Bakke

    In response to the declining number of students in the United States entering into the STEM (science, technology, engineering, and math) disciplines, there has been an attempt to retain student interest in the sciences through the implementation of more active learning in the classroom. Active learning is defined as any instructional method that requires students do something in the classroom rather than simply listen to a lecture (Herreid, 2006). These student centered approaches provide the students with the opportunity to work cooperatively while developing the skills required for critical inquiry. They also help the students make the connections between what is being taught and how it can be applied in a real world setting. Science education researchers have attempted to analyze the efficacy of active learning. Although they find it difficult to compare the data, they state unequivocally that "Active learning is a better strategy for learning than the traditional didactic lecture format" (Prince, 2004). However, even though research supports the efficacy of active learning, instructors find it difficult to adopt this pedagogy into their classrooms due to concerns such as loss of content knowledge and student resistance. This three year qualitative and quantitative study addressed the level of student learning and satisfaction in an introductory vertebrate biology class at a small liberal arts college. The courses were taught by the same instructor using three pedagogical methods; traditional lecture (TL), problem-based learning (PBL), and case-based learning (CBL). Student grades and levels of assessment were compared between the TL and PBL, while student attrition rates, course satisfaction and views of active and group learning were analyzed across all three sections. The evolutionary confirmations from TL to PBL and ultimately the adoption of CBL as the method of choice are discussed from the view of both the faculty member and the students.

    To test the hypothesis that lecturing maximizes learning and course performance, we metaanalyzed 225 studies that reported data on examination scores or failure rates when comparing student performance in undergraduate science, technology, engineering, and mathematics (STEM) courses under traditional lecturing versus active learning. The effect sizes indicate that on average, student performance on examinations and concept inventories increased by 0.47 SDs under active learning (n = 158 studies), and that the odds ratio for failing was 1.95 under traditional lecturing (n = 67 studies). These results indicate that average examination scores improved by about 6% in active learning sections, and that students in classes with traditional lecturing were 1.5 times more likely to fail than were students in classes with active learning. Heterogeneity analyses indicated that both results hold across the STEM disciplines, that active learning increases scores on concept inventories more than on course examinations, and that active learning appears effective across all class sizes--although the greatest effects are in small (n ≤ 50) classes. Trim and fill analyses and fail-safe n calculations suggest that the results are not due to publication bias. The results also appear robust to variation in the methodological rigor of the included studies, based on the quality of controls over student quality and instructor identity. This is the largest and most comprehensive metaanalysis of undergraduate STEM education published to date. The results raise questions about the continued use of traditional lecturing as a control in research studies, and support active learning as the preferred, empirically validated teaching practice in regular classrooms.

    Unmanned Aerial System (UAS) are becoming popular tools in the geosciences due to improving technology and processing/analysis techniques. They can potentially fill the gap between spaceborne or manned aircraft remote sensing and terrestrial remote sensing, both in terms of spatial and temporal resolution. In this study we analyze a multi-temporal data set that was acquired with a fixed-wing UAS in an agricultural catchment (2 sq. km) in Navarra, Spain. The goal of this study is to register soil erosion activity after one year of agricultural activity. The aircraft was equipped with a Panasonic GX1 16MP pocket camera with a 20 mm lens to capture normal JPEG RGB images. The data set consisted of two sets of imagery acquired in the end of February in 2013 and 2014 after harvesting. The raw images were processed using Agisoft Photoscan Pro which includes the structure-from-motion (SfM) and multi-view stereopsis (MVS) algorithms producing digital surface models and orthophotos of both data sets. A discussion is presented that is focused on the suitability of multi-temporal UAS data and SfM/MVS processing for quantifying soil loss, mapping the distribution of eroded materials and analyzing re-occurrences of rill patterns after plowing.

    Background Research is the foundation of scientific advancement and improvement in quality of health care, which ensures the good health of the community. The aim of this study is to explore experiences, attitudes, and barriers of medical students in Kuwait University (KU) in regards to extracurricular research. Methods A questionnaire about extracurricular research activities (ie, any research activity that is not part of the required undergraduate curriculum, such as publishing a paper, research elective, etc) was distributed to 175 senior medical students (years 6 and 7). Descriptive and chi-square analyses were used to analyze the responses, considering a P-value of <0.05 as the cut-off level for significance. The main outcome was defined as taking part in any of the extracurricular research activities. Results Of the 150 participants (response rate = 85.7%), 26 (17.3%), 68 (45.3%), 52 (34.7%), and 17 (11.3%) had published their required medical school research, presented abstracts in conferences, conducted extracurricular research, and completed a research elective/course, respectively; 99 (66.0%) took part in any of these activities. Participants who read medical journals regularly (81; 54%) reported higher participation in extracurricular research activities than those who did not read journals (P=0.003). Improving the availability of mentors for students’ extracurricular research was ranked by the participants as the most important factor to improve their participation in extracurricular research (4.05/5.00). Conclusion Despite the lack of adequate support, extracurricular research activities among medical students of KU were comparable to students from other countries. Barriers for these activities should be addressed by KU medical educators in order to enhance research activities among the students. PMID:24812535

    Optical imaging (OI) is a relatively new method in detecting active inflammation of hand joints of patients suffering from rheumatoid arthritis (RA). With the high number of people affected by this disease especially in western countries, the availability of OI as an early diagnostic imaging method is clinically highly relevant. In this paper, we present a newly in-house developed OI analyzing tool and a clinical evaluation study. Our analyzing tool extends the capability of existing OI tools. We include many features in the tool, such as region-based image analysis, hyper perfusion curve analysis, and multi-modality image fusion to aid clinicians in localizing and determining the intensity of inflammation in joints. Additionally, image data management options, such as the full integration of PACS/RIS, are included. In our clinical study we demonstrate how OI facilitates the detection of active inflammation in rheumatoid arthritis. The preliminary clinical results indicate a sensitivity of 43.5%, a specificity of 80.3%, an accuracy of 65.7%, a positive predictive value of 76.6%, and a negative predictive value of 64.9% in relation to clinical results from MRI. The accuracy of inflammation detection serves as evidence to the potential of OI as a useful imaging modality for early detection of active inflammation in patients with rheumatoid arthritis. With our in-house developed tool we extend the usefulness of OI imaging in the clinical arena. Overall, we show that OI is a fast, inexpensive, non-invasive and nonionizing yet highly sensitive and accurate imaging modality.-

    OBJECTIVE Translate the Patient-centered Assessment and Counseling for Exercise questionnaire, adapt it cross-culturally and identify the psychometric properties of the psychosocial scales for physical activity in young university students. METHODS The Patient-centered Assessment and Counseling for Exercise questionnaire is made up of 39 items divided into constructs based on the social cognitive theory and the transtheoretical model. The analyzed constructs were, as follows: behavior change strategy (15 items), decision-making process (10), self-efficacy (6), support from family (4), and support from friends (4). The validation procedures were conceptual, semantic, operational, and functional equivalences, in addition to the equivalence of the items and of measurements. The conceptual, of items and semantic equivalences were performed by a specialized committee. During measurement equivalence, the instrument was applied to 717 university students. Exploratory factor analysis was used to verify the loading of each item, explained variance and internal consistency of the constructs. Reproducibility was measured by means of intraclass correlation coefficient. RESULTS The two translations were equivalent and back-translation was similar to the original version, with few adaptations. The layout, presentation order of the constructs and items from the original version were kept in the same form as the original instrument. The sample size was adequate and was evaluated by the Kaiser-Meyer-Olkin test, with values between 0.72 and 0.91. The correlation matrix of the items presented r < 0.8 (p < 0.05). The factor loadings of the items from all the constructs were satisfactory (> 0.40), varying between 0.43 and 0.80, which explained between 45.4% and 59.0% of the variance. Internal consistency was satisfactory (α ≥ 0.70), with support from friends being 0.70 and 0.92 for self-efficacy. Most items (74.3%) presented values above 0.70 for the reproducibility test

    Farrar, Cathy

    As part of the National Science Foundation Science Literacy through Science Journalism (SciJourn) research and development initiative (http://www.scijourn.org ; Polman, Saul, Newman, and Farrar, 2008) a quasi-experimental design was used to investigate what impact incorporating science journalism activities had on students' scientific literacy. Over the course of a school year students participated in a variety of activities culminating in the production of science news articles for Scijourner, a regional print and online high school science news magazine. Participating teachers and SciJourn team members collaboratively developed activities focused on five aspects of scientific literacy: placing information into context, recognizing relevance, evaluating factual accuracy, use of multiple credible sources and information seeking processes. This study details the development process for the Scientific Literacy Assessment (SLA) including validity and reliability studies, evaluates student scientific literacy using the SLA, examines student SLA responses to provide a description of high school students' scientific literacy, and outlines implications of the findings in relation to the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012) and classroom science teaching practices. Scientifically literate adults acting as experts in the assessment development phase informed the creation of a scoring guide that was used to analyze student responses. Experts tended to draw on both their understanding of science concepts and life experiences to formulate answers; paying close attention to scientific factual inaccuracies, sources of information, how new information fit into their view of science and society as well as targeted strategies for information seeking. Novices (i.e., students), in contrast, tended to ignore factual inaccuracies, showed little understanding about source credibility and suggested

    A commercial antacid suspension containing aluminum hydroxide and magnesium hydroxide products was used as a model sample to study the use of a californium-252 thermal neutron activation as a method for quantifying aluminum content as well as for the simultaneous assay of aluminum and magnesium. A 3.5-micrograms californium-252 source was used for the activation, and the induced aluminum-28 and magnesium-27 activity was simultaneously measured by sodium iodide crystal gamma-ray spectrometry using dual single-channel analyzers and scalers. The antacid suspension was contained in a chamber designed with the unique capability of serving as the container for counting the induced radioactivity in addition to being the irradiation chamber itself. Ten replicate irradiations were performed, and the precision was compared with 10 replicate analyses of the antacid suspension using the official ethylenediaminetetraacetic acid titration method. For aluminum the precision was 1.4 versus 0.62% for the titration method. For the magnesium the precision was 5.3 versus 0.79% for the titration method. This pilot study demonstrated that use of more intense californium-252 sources, which are commonly available, would provide a method that is competitive with the ethylenediaminetetraacetic acid titration method in precision and in other aspects as well.

    Astronomical Activities for students Motivating students interest in Physical Science through Astronomy Alexis Matthaiou Philekpaideftiki Etaireia, Arsakeio Lyceum Patron, Patras, Greece,(alexiosmat@yahoo.gr) School education aims not only to providing the necessary knowledge to the students but also to inspire and motivate them to realize their special abilities and inclinations and use their potential for making a joyful future for their lives. In this direction we present some activities held in the Arsakeio School of Patras during the years 2005-2008 in the field of Astronomy and Astrophysics, in order to share our experience with the teachers' community. Students from all grades of primary and secondary education participated with enthusiasm. In particular, they observed the Partial Solar Eclipse of October 3rd, 2005,and the Total Solar Eclipse of March 29th, 2006. They took part in observing and registering Solar Spots, using Astronomical equipments like different types of telescopes with filters and solar scopes. Students studied further the nature of Solar Phenomena and their effects on life, participating in the Environmental Program "Sun and Life"(2006-2007). Moreover, students took part in the International Program for measuring the Light Pollution "Globe at Night" (2006-2007) with observing and registering the luminosity of the Orion constellation in the night sky above their residence. Finally, the students participated in the European program "Hands on Universe" (HOU) (2005-2008) working on a project, which was the Greek contribution to HOU, developed from "Philekpaideftiki Etaireia". In particular, they studied the stars' spectrum and acquired information about the stars' life and age of stellar systems, using interactive multimedia technology.

  3. An investigation of the impact of selected prereading activities on student content learning through laboratory activities

    NASA Astrophysics Data System (ADS)

    Kass, Jesse (Shaya)

    This study investigated whether two prereading activities impacted student learning from hands-on science activities. The study was based on constructivist learning theory. Based on the work of Piaget, it was hypothesized that students who activated prior knowledge would learn more from the activities. Based on the work of Vygotsky it was hypothesized that students who talk more and write more would learn more from the activity. The K-W-L chart and anticipation guide strategies were used with eighth grade students at Graves Middle School in Whittier, California before learning about levers and convection currents. D. M. Ogle (1986) created the three-column K-W-L chart to have students activate prior knowledge. In the first column, the students write what they already know about a subject, in the second column, the students write what they want to know about the subject, and the students complete the third column after learning about a subject by writing answers to the questions that they asked in the second column. Duffelmeyer (1994) created the anticipation guide based on Herber's (1978) reasoning guide. In the anticipation guide, the teacher creates three or four sentences that convey the major ideas of the topic and the students either agree or disagree with the statements. After learning about the topic, students revisit their answers and decide if they were correct or incorrect and they must defend their choices. This research used the Solomon (1947) four-square design and compared both the experimental groups to a control group that simply discussed the concepts before completing the activity. The research showed no significant difference between the control group and either of the treatment groups. The reasons for the lack of significant differences are considered. It was hypothesized that since the students were unfamiliar with the prereading activities and did not have much experience with using either writing-to-learn or talking-to-learn strategies, the

    1995-01-01

    Basic nursing education is governed by individual state rules and regulations lacking in uniformity across the United States and based on unstated and perhaps mistaken assumptions. At the same time, there is increasing evidence of problems and difficulties with the current traditional model of nursing education. Before proposing changes in said model, the authors chose to examine what it is that a nursing student does in a clinical area. The perspective of activities and interactions was chosen to illustrate, through a nonparticipant observation study, the patterns and utilization of time during a scheduled clinical experience for baccalaureate nursing students. The goal of the study was to determine who, other than the client/patient, influences the student learning at the clinical site and how learning time is spent. Two schools (one private and one public) and nine clinical sites with 37 observations were used to collect the data for this study. Findings are best summarized in four (overlapping) categories of school time, registered nurse (RN) staff time, hospital staff time, and supervised time. School time, or time spent interacting with the instructor, another student, and/or the student on his/her own in the practice setting (time exclusive of staff input) constituted 84 per cent of all time. RN staff time that was time spent with either the primary nurse or other RNs on the unit used 10 per cent of the student time, Fourteen per cent of student time was spent in hospital staff time, which includes interactions with any nursing staff or other hospital personnel.(ABSTRACT TRUNCATED AT 250 WORDS)

  6. Distinguishing two groups of flavin reductases by analyzing the protonation state of an active site carboxylic acid.

    2011-07-01

    Flavin-containing reductases are involved in a wide variety of physiological reactions such as photosynthesis, nitric oxide synthesis, and detoxification of foreign compounds, including therapeutic drugs. Ferredoxin-NADP(H)-reductase (FNR) is the prototypical enzyme of this family. The fold of this protein is highly conserved and occurs as one domain of several multidomain enzymes such as the members of the diflavin reductase family. The enzymes of this family have emerged as fusion of a FNR and a flavodoxin. Although the active sites of these enzymes are very similar, different enzymes function in opposite directions, that is, some reduce oxidized nicotinamide adenine dinucleotide phosphate (NADP(+)) and some oxidize reduced nicotinamide adenine dinucleotide phosphate (NADPH). In this work, we analyze the protonation behavior of titratable residues of these enzymes through electrostatic calculations. We find that a highly conserved carboxylic acid in the active site shows a different titration behavior in different flavin reductases. This residue is deprotonated in flavin reductases present in plastids, but protonated in bacterial counterparts and in diflavin reductases. The protonation state of the carboxylic acid may also influence substrate binding. The physiological substrate for plastidic enzymes is NADP(+), but it is NADPH for the other mentioned reductases. In this article, we discuss the relevance of the environment of this residue for its protonation and its importance in catalysis. Our results allow to reinterpret and explain experimental data.

    Canarsie High School is a typical urban high school in Brooklyn, New York. We have been involved in a District Initiative in collaboration with the City College of New York (CCNY) to initiate and incorporate relevant technologies into the science content areas and classrooms. Through changes in teaching strategies consistent with science education reform movements for mainstream, gifted and special education students; we have been able to effectively motivate student interest and to enhance and enrich the learning potential of all students. Our lessons involve extensive computer and Internet applications, concentrating our efforts in developing high-ordered reasoning skills to address the required concepts covered in Earth Science and Environmental Science curricula. This is a crucial aspect of applied learning approaches as related science concepts are integrated and clearly demonstrated in our daily lives. Our task was to infuse 'live' weather data into Earth Science and Environmental Science classrooms. Student-centered learning activities, laboratory experiences and long-term investigations were designed, written and included into classroom lessons and laboratory sections. This component is aligned with the New Learning and Performance Standards, and makes use of investigative and inquiry-based studies through technological resources. These were accomplished through data readings taken from our school weather station and various World Wide Web sites. Weather data from area "cluster" schools were also used to compare micro-climates within our local region. This fostered peer communication skills among students and staff throughout the Brooklyn High School District.

    2016-01-01

    Context: Active learning has received considerable attention over the past several years, often presented or perceived as a radical change from traditional instruction methods. Current research on learning indicates that using a variety of teaching strategies in the classroom increases student participation and learning. Aim and Objectives: To introduce active learning methodology, i.e., “jigsaw technique” in undergraduate medical education and assess the student and faculty response to it. Subjects and Methods: This study was carried out in the Department of Physiology in a Medical College of North India. A topic was chosen and taught using one of the active learning methods (ALMs), i.e., jigsaw technique. An instrument (questionnaire) was developed in English through an extensive review of literature and was properly validated. The students were asked to give their response on a five-point Likert scale. The feedback was kept anonymous. Faculty also provided their feedback in a separately provided feedback proforma. The data were collected, compiled, and analyzed. Results: Of 150 students of MBBS-first year batch 2014, 142 participated in this study along with 14 faculty members of the Physiology Department. The majority of the students (>90%) did welcome the introduction of ALM and strongly recommended the use of such methods in teaching many more topics in future. 100% faculty members were of the opinion that many more topics shall be taken up using ALMs. Conclusion: This study establishes the fact that both the medical students and faculty want a change from the traditional way of passive, teacher-centric learning, to the more active teaching-learning techniques.

    The objective of this project was to expose and train multiple students in geological tools that are essential to reservoir characterization and geologic sequestration including but not limited to advanced petrological methods, mineralogical methods, and geochemical methods; core analysis, and geophysical well-log interpretation. These efforts have included training of multiple students through geologically based curriculum and research using advanced petrological, mineralogical, and geochemical methods. In whole, over the last 3+ years, this award has supported 5,828 hours of student research, supporting the work of several graduate and undergraduate students. They have all received training directly related to ongoing CO{sub 2} sequestration demonstrations. The students have all conducted original scientific research on topics related to understanding the importance of lithological, textural, and compositional variability in formations that are being targeted as CO{sub 2} sequestration reservoirs and seals. This research was linked to the Mount Simon Sandstone reservoir and overlying Eau Claire Formation seal in the Illinois Basin- a system where over one million tons of CO{sub 2} are actively being injected with the first large-scale demonstration of anthropogenic CO{sub 2} storage in the U.S. Student projects focused specifically on 1) reservoir porosity characterization and evaluation, 2) petrographic, mineralogical, and geochemical evidence of fluid-related diagenesis in the caprock, 3) textural changes in reservoir samples exposed to experimental CO{sub 2} + brine conditions, 4) controls on spatial heterogeneity in composition and texture in both the reservoir and seal, 5) the implications of small-scale fractures within the reservoir, and 6) petrographic and stable isotope analyses of carbonates in the seal to understand the burial history of the system.

Three researchers from the project later formed Microsensor Technology, Inc. (MTI) to commercialize the analyzer. The original version (Micromonitor 500) was introduced in 1982, and the M200 in 1988. The M200, a more advanced version, features dual gas chromatograph which separate a gaseous mixture into components and measure concentrations of each gas. It is useful for monitoring gas leaks, chemical spills, etc. Many analyses are completed in less than 30 seconds, and a wide range of mixtures can be analyzed.

    The ChemScan UV-6100 is a spectrometry system originally developed by Biotronics Technologies, Inc. under a Small Business Innovation Research (SBIR) contract. It is marketed to the water and wastewater treatment industries, replacing "grab sampling" with on-line data collection. It analyzes the light absorbance characteristics of a water sample, simultaneously detects hundreds of individual wavelengths absorbed by chemical substances in a process solution, and quantifies the information. Spectral data is then processed by ChemScan analyzer and compared with calibration files in the system's memory in order to calculate concentrations of chemical substances that cause UV light absorbance in specific patterns. Monitored substances can be analyzed for quality and quantity. Applications include detection of a variety of substances, and the information provided enables an operator to control a process more efficiently.

  2. Hypothetical biotechnology companies: A role-playing student centered activity for undergraduate science students.

    PubMed

    Chuck, Jo-Anne

    2011-01-01

    Science students leaving undergraduate programs are entering the biotechnology industry where they are presented with issues which require integration of science content. Students find this difficult as through-out their studies, most content is limited to a single subdiscipline (e.g., biochemistry, immunology). In addition, students need knowledge of the ethical, economic, and legal frame work in which the industry operates. This article presents an approach to deliver these outcomes in a collaborative and active learning modality which promotes deep learning. In the model, groups of final year undergraduate students form hypothetical biotechnology companies and identify real issues of interest to industry, make integrative team decisions, use professional level technology, and develop appropriate communication skills. The final successful teaching paradigm was based on self reflection, observation, and student feedback to ensure appropriate attainment of content, group work skills and increased confidence in professional decision-making. It is these outcomes which will facilitate life long learning skills, a major outcome applicable for all tertiary education.

  3. Defibrillator analyzers.

    PubMed

    1999-12-01

    Defibrillator analyzers automate the inspection and preventive maintenance (IPM) testing of defibrillators. They need to be able to test at least four basic defibrillator performance characteristics: discharge energy, synchronized-mode operation, automated external defibrillation, and ECG monitoring. We prefer that they also be able to test a defibrillator's external noninvasive pacing function--but this is not essential if a facility already has a pacemaker analyzer that can perform this testing. In this Evaluation, we tested seven defibrillator analyzers from six suppliers. All seven units accurately measure the energies of a variety of discharge wave-forms over a wide range of energy levels--from 1 J for use in a neonatal intensive care unit to 360 J for use on adult patients requiring maximum discharge energy. Most of the analyzers are easy to use. However, only three of the evaluated units could perform the full range of defibrillator tests that we prefer. We rated these units Acceptable--Preferred. Three more units could perform four of the five tests, they could not test the pacing feature of a defibrillator. These units were rated Acceptable. The seventh unit could perform only discharge energy testing and synchronized-mode testing and was difficult to use. We rate that unit Acceptable--Not Recommended. PMID:10604089

  4. Gender Difference in Academic Planning Activity among Medical Students

    Nguyen, Huy Van; Giang, Thao Thach

    2013-01-01

    Background In Vietnam, as doctor of medicine is socially considered a special career, both men and women who are enrolled in medical universities often study topics of medicine seriously. However, as culturally expected, women often perform better than men. Because of this, teaching leadership and management skill (LMS) to develop academic planning activity (APA) for female medical students would also be expected to be more effective than male counterparts. This research aimed to compare by gender the effect of teaching LMS on increasing APA, using propensity score matching (PSM). Methods In a cross-sectional survey utilizing a self-reported structured questionnaire on a systematic random sample of 421 male and female medical students in Hanoi Medical University, this study adopted first regression techniques to construct a fit model, then PSM to create a matched control group in order to allow for evaluating the effect of LMS education. Results There were several interesting gender differences. First, while for females LMS education had both direct and indirect effects on APA, it had only direct effect on males’ APA. Second, after PSM to adjust for the possible confounders to balance statistically two groups – with and without LMS education, there is statistically a significant difference in APA between male and female students, making a net difference of 11% (p<.01), equivalent to 173 students. The difference in APA between exposed and matched control group in males and females was 9% and 20%, respectively. These estimates of 9.0 and 20.0 percentage point increase can be translated into the practice of APA by 142 males and 315 females, respectively, in the population. These numbers of APA among male and female students can be explained by LMS education. Conclusions Gender appears to be a factor explaining in part academic planning activity. PMID:23418467

    We describe the development and implementation of an instructional design that focused on bringing multiple forms of active learning and student-centered pedagogies to a one-semester, undergraduate introductory biology course for both majors and nonmajors. Our course redesign consisted of three major elements: 1) reordering the presentation of the course content in an attempt to teach specific content within the context of broad conceptual themes, 2) incorporating active and problem-based learning into every lecture, and 3) adopting strategies to create a more student-centered learning environment. Assessment of our instructional design consisted of a student survey and comparison of final exam performance across 3 years-1 year before our course redesign was implemented (2006) and during two successive years of implementation (2007 and 2008). The course restructuring led to significant improvement of self-reported student engagement and satisfaction and increased academic performance. We discuss the successes and ongoing challenges of our course restructuring and consider issues relevant to institutional change.

    2014-12-01

    Scientific literacy has been defined as the foremost challenge of this decade (AAAS, 2012). The Geological Society of American in its position statement postis that due to the systemic nature of the discipline of earth science, it is the most effective way to engage students in STEM disciplines. Given that the most common place for exposure to earth sciences is at the freshman level for non majors, we decided to transform a freshman introductory geology course to an active, student centered course, using an inquiry based approach. Our focus was to ensure the students saw the earth sciences as broadly applicative field, and not an esoteric science. To achieve this goal, we developed a series of problems that required the students to apply the concepts acquired through their self guided learning into the different topics of the course. This self guided learning took the form of didactic content uploaded into the learning management system (the various elements used to deliver the content were designed video clips, short text based lectures, short formative assessments, discussion boards and other web based discovery exercises) with the class time devoted to problem solving. A comparison of student performance in the active learning classroom vs. a traditional classroom as measured on a geoscience concept inventory (the questions were chosen by a third party who was not teaching either courses) showed that the the students in the active learning classroom scored 10% higher on the average in comparison to the traditional class. In addition to this heightened performance, the students in the active classroom also showed a higher degree of content retention 8 weeks after the semester had ended. This session will share the design process, some exercises and efficacy data collected.

    Measurement of the total organic carbon content in water is important in assessing contamination levels in high purity water for power generation, pharmaceutical production and electronics manufacture. Even trace levels of organic compounds can cause defects in manufactured products. The Sievers Model 800 Total Organic Carbon (TOC) Analyzer, based on technology developed for the Space Station, uses a strong chemical oxidizing agent and ultraviolet light to convert organic compounds in water to carbon dioxide. After ionizing the carbon dioxide, the amount of ions is determined by measuring the conductivity of the deionized water. The new technique is highly sensitive, does not require compressed gas, and maintenance is minimal.

    Background. Physical activity (PA), sedentary behaviors, and dietary behaviors are each associated with overweight and obesity among youth. However, the associations of PA and sedentary behaviors with dietary behaviors are complex and not well understood. Purpose. To describe the associations of PA and sedentary behaviors with dietary behaviors among a representative sample of US high school students. Methods. We analyzed data from the 2010 National Youth Physical Activity and Nutrition Study (NYPANS). Using logistic regression models which controlled for sex, race/ethnicity, grade, body weight status, and weight management goals, we compared dietary behaviors among students who did and did not meet national recommendations for PA and sedentary behaviors. Results. Students who participated in recommended levels of daily PA (DPA) and muscle strengthening PA (MSPA) were more likely than those who did not to eat fruits and vegetables. Students who exceeded recommended limits for television (TV) and computer/video game (C/VG) screen time were less likely than those who did not to consume fruits and vegetables and were more likely to consume fast food and sugar-sweetened beverages. Conclusions. Researchers may want to address PA, sedentary behaviors, and dietary behaviors jointly when developing health promotion and obesity prevention programs for youth. PMID:26101666

    Microarray-based genomic technology has been widely used for microbial community analysis, and it is expected that microarray-based genomic technologies will revolutionize the analysis of microbial community structure, function and dynamics. A new generation of functional gene arrays (GeoChip 3.0) has been developed, with 27,812 probes covering 56,990 gene variants from 292 functional gene families involved in carbon, nitrogen, phosphorus and sulfur cycles, energy metabolism, antibiotic resistance, metal resistance, and organic contaminant degradation. Those probes were derived from 2,744, 140, and 262 species for bacteria, archaea, and fungi, respectively. GeoChip 3.0 has several other distinct features, such as a common oligo reference standard (CORS) for data normalization and comparison, a software package for data management and future updating, and the gyrB gene for phylogenetic analysis. Our computational evaluation of probe specificity indicated that all designed probes had a high specificity to their corresponding targets. Also, experimental analysis with synthesized oligonucleotides and genomic DNAs showed that only 0.0036percent-0.025percent false positive rates were observed, suggesting that the designed probes are highly specific under the experimental conditions examined. In addition, GeoChip 3.0 was applied to analyze soil microbial communities in a multifactor grassland ecosystem in Minnesota, USA, which demonstrated that the structure, composition, and potential activity of soil microbial communities significantly changed with the plant species diversity. All results indicate that GeoChip 3.0 is a high throughput powerful tool for studying microbial community functional structure, and linking microbial communities to ecosystem processes and functioning. To our knowledge, GeoChip 3.0 is the most comprehensive microarrays currently available for studying microbial communities associated with geobiochemical cycling, global climate change, bioenergy

    An optical analyzer wherein a sample of particulate matter, and particularly of organic matter, which has been collected on a quartz fiber filter is placed in a combustion tube, and light from a light source is passed through the sample. The temperature of the sample is raised at a controlled rate and in a controlled atmosphere. The magnitude of the transmission of light through the sample is detected as the temperature is raised. A data processor, differentiator and a two pen recorder provide a chart of the optical transmission versus temperature and the rate of change of optical transmission versus temperature signatures (T and D) of the sample. These signatures provide information as to physical and chemical processes and a variety of quantitative and qualitative information about the sample. Additional information is obtained by repeating the run in different atmospheres and/or different rates or heating with other samples of the same particulate material collected on other filters. 7 figs.

    To investigate the relations among leisure time physical activity and in sport clubs, lifestyle activities, and the locomotor, balance manipulative skills of Grade 7 students participating in Finnish physical education at a secondary school in central Finland completed self-report questionnaires on their physical activity patterns at leisure time and during sport club participation, and time spent watching television and using the computer and other electronic media. Locomotor skills were analyzed by the leaping test, balance skills by the flamingo standing test, and manipulative skills by the accuracy throwing test. Analysis indicated physical activity in sport clubs positively explained scores on balance and locomotor tests but not on accuracy of throwing. Leisure time physical activity and lifestyle activities were not statistically significant predictors of performance on any movement skill tests. Girls scored higher on the static balance skill and boys higher on the throwing task. Overall, physical activity in sport clubs was more strongly associated with performance on the fundamental movement tasks than was physical activity during leisure. PMID:19425451

    2006-01-01

    There is growing evidence that social rhythms (e.g., daily activities such as getting into or out of bed, eating, and adhering to a work schedule) have important implications for sleep. The present study used a prospective measure of daily activities to assess the relation between sleep and social rhythms. College students (n=243) 18 to 39 yrs of age, completed the Social Rhythm Metric (SRM) each day for 14 d and then completed the Pittsburgh Sleep Quality Index (PSQI). The sample was divided into groups of good or poor sleepers, according to a PSQI cut-off score of 5 points and was compared on the regularity, frequency, timing, and extent of social engagement during activities. There was a lower frequency and less regularity of social rhythms in poor sleepers relative to good sleepers. Good sleepers engaged more regularly in activities with active social engagement. Earlier rise time, first consumption of a beverage, going outdoors for the first time, and bedtime were associated with better sleep. Greater variability in rise time, consuming a morning beverage, returning home for the last time, and bedtime were associated with more disturbed sleep. The results are consistent with previous findings of reduced regularity in bedtime and rise time schedules in undergraduates, other age groups, and in clinical populations. Results augment the current thought that regulating behavioral zeitgebers may be important in influencing bed and rise times, and suggest that engaging in activities with other people may increase regularity.

    1989-02-07

    An optical analyzer (10) wherein a sample (19) of particulate matter, and particularly of organic matter, which has been collected on a quartz fiber filter (20) is placed in a combustion tube (11), and light from a light source (14) is passed through the sample (19). The temperature of the sample (19) is raised at a controlled rate and in a controlled atmosphere. The magnitude of the transmission of light through the sample (19) is detected (18) as the temperature is raised. A data processor (23), differentiator (28) and a two pen recorder (24) provide a chart of the optical transmission versus temperature and the rate of change of optical transmission versus temperature signatures (T and D) of the sample (19). These signatures provide information as to physical and chemical processes and a variety of quantitative and qualitative information about the sample (19). Additional information is obtained by repeating the run in different atmospheres and/or different rates of heating with other samples of the same particulate material collected on other filters.

  15. Socially situated activities and identities: Second-grade dual language students and the social construction of science

    Bryce, Nadine

    Latina and Latino American students are among the lowest achievers in science, when compared to European and Asian American students, and are highly underrepresented in science careers. Studies suggested that a part of this problem is students' lack of access to science, due to their status as English language learners and their perceived status as deficient students. This study investigated the social construction of science in a second grade dual language urban classroom that offered bilingual students access to science, while positioning them as competent, capable learners. What participants valued in science was interpreted from their stated beliefs and attitudes, as well as their patterned ways of reading, writing, and talking. A bilingual European American teacher and three Latina and Latino focal students were observed over the course of 10 weeks, as they enacted a science unit, in English, on habitats. Science lessons were videotaped, documented with field notes, and transcribed. Interviews with the teacher and students were audiotaped and transcribed, and relevant curriculum documents, and teacher- and student-generated documents, copied. Gee's (1999) d/Discourse analysis system was applied to the transcripts of science lessons and interviews as a way to understand how participants used language to construct situated activities and identities in science. Curriculum documents were analyzed to understand the positioning of the teacher and students by identifying the situated activities and roles recommended. Students' nonfiction writing and published nonfiction texts were analyzed for linguistic structures, semantic relationships and conventions of science writing. Results indicated that the teacher drew on traditional and progressive pedagogical practices that shaped her and her students' science activities and situated identities. The teacher employed traditional talk strategies to build science themes, while students enacted their roles as compliant

    1961-11-14

    A means was developed for continuously computing and indicating the isotopic assay of a process solution and for automatically controlling the process output of isotope separation equipment to provide a continuous output of the desired isotopic ratio. A counter tube is surrounded with a sample to be analyzed so that the tube is exactly in the center of the sample. A source of fast neutrons is provided and is spaced from the sample. The neutrons from the source are thermalized by causing them to pass through a neutron moderator, and the neutrons are allowed to diffuse radially through the sample to actuate the counter. A reference counter in a known sample of pure solvent is also actuated by the thermal neutrons from the neutron source. The number of neutrons which actuate the detectors is a function of a concentration of the elements in solution and their neutron absorption cross sections. The pulses produced by the detectors responsive to each neu tron passing therethrough are amplified and counted. The respective times required to accumulate a selected number of counts are measured by associated timing devices. The concentration of a particular element in solution may be determined by utilizing the following relation: T2/Ti = BCR, where B is a constant proportional to the absorption cross sections, T2 is the time of count collection for the unknown solution, Ti is the time of count collection for the pure solvent, R is the isotopic ratlo, and C is the molar concentration of the element to be determined. Knowing the slope constant B for any element and when the chemical concentration is known, the isotopic concentration may be readily determined, and conversely when the isotopic ratio is known, the chemical concentrations may be determined.

    This study was conducted to examine the effectiveness of an analogy activity, which was designed to overcome junior high students' misconceptions about the microscopic views of phase change. Eighty Taiwanese 8 th graders were randomly assigned to either a control group or an experimental group. For the control group, the subjects were instructed through traditional teaching whereas for the experimental group, an analogy activity was conducted on students. This specific analogy activity was presented in the form of role-playing in which students acted as particles and worked together to perform the conditions of phase changes. Through analyzing these students' drawings of the atom arrangements for the three states of some substances, it was found that the students of experimental group, though in many cases, did not perform statistically better than did those of control group in an immediate posttest. The comparisons of a delay test between these two groups indicated that the analogy activity had clearly positive impacts on students' conceptual change on these scientific concepts in terms of long-term observations.

  7. Predictors of Student Persistence in the STEM Pipeline: Activities Outside the Classroom, Parent Aspirations, and Student Self-Beliefs using NELS:88 Data

    Miller, Joelle A.

    Focusing on Science, Technology, Engineering and Mathematics (STEM) literacy is a national priority for the United States. As competition increases internationally for scientific and technological innovations, the United States is concentrating on building its STEM capacity (Stephens, 2011). Despite the numerous STEM reform efforts there continues to be a decline in STEM graduates and STEM competencies (McNally, 2012; Langdon, Mckittrick, Beede, Doms, & Khan, 2011; Herschback, 2011). With attention focused on increasing STEM college majors and occupations among the student population, the current research investigation centered on the role of parent aspirations, student self-beliefs, and activities outside the classroom to determine the outcome of middle and high school students choosing a STEM college major. Research suggested that students formulate their degree attainment during their middle and high school years, and even earlier (Roach, 2006; Maltese & Tai, 2011); therefore, it was logical to investigate STEM persistence during middle and high school years. The study analyzed NELS:88, a longitudinal national public data set created by the National Center for Educational Statistics that used 12,144 participants. The students' self-reported data spanned over a 12-year period. Students completed five surveys in the NELS:88 data collection (NCES, 2011). Binary and multivariate logistical regressions determined if activities outside the classroom, parent aspirations, and student self-beliefs influenced STEM college majors. Conclusions of the study found significant relationships between the variables and STEM persistence. Individuals who participated in STEM activities after school were more likely to major in STEM (p<.001,Exp(B)=1.106). There was a significant positive relationship between parent aspirations and increased odds of choosing a STEM major (p<.0001, Exp(B)=1.041). There was a significant relationship between student self-beliefs and choosing a STEM

    This article provides a systematic literature review on physical activity and/or healthy eating interventions among Brazilian students. Complete articles published from 2004 to 2009 were searched in the SciELO, MEDLINE, and CAPES electronic databases, in the articles' references, and through contacts with authors. Six studies covered nutritional interventions, another six analyzed nutrition and physical activity, and one discussed changes in body composition. Interventions produced different results according to their objectives: increase in weekly physical activity; improvement in eating habits and knowledge on nutrition; and decrease in overweight and obesity. School health promotion programs are essential for raising awareness on the relevance of health promotion and the adoption of healthy habits. However, further longitudinal studies are needed to produce evidence on sustainability of programs and healthy habits.

    Generally, boiling of vegetables is assumed leading to lower nutritional values because of leaching effects and activity loss of bioactive compounds. Kale (Brassica oleracea var. sabellica) reveals a great diversity of flavonoids, which have been shown to be good antioxidants. As Brassica vegetables are mainly consumed cooked, the influence of boiling on kale's flavonoids and their antioxidant activity was investigated. Therefore, three kale cultivars were cooked at 100°C for 2 and 4h prior to analysis. The total phenolic content (TPC) and the total antioxidant activity (TEAC assay and EPR spectrometry) of each cultivar were determined and revealed no change, independent of cooking time, although kale samples visually altered. Using the HPLC-UV/Vis-online-TEAC approach, distinct changes in composition and antioxidant activity of the flavonoids were detectable. Thus, it was observable, that the antioxidant activities of the reaction products compensated the "loss" of the antioxidant activity of the original compounds of the uncooked material.

    Understanding correlates of physical activity (PA) can help inform and improve programs that promote PA among youth. We analyzed data from the 2010 National Youth Physical Activity and Nutrition Study, a representative sample of US students in grades 9-12. Logistic regression was used to examine associations between PA correlates (obesity, physical education classes, sports team participation, attitude toward PA, adult support for PA, and environmental support for PA) and participation in daily PA (DPA), vigorous PA (VPA), muscle-strengthening activity (MSA), viewing television (TV), and using computers or video games (C/VG). A positive attitude toward PA and adult support for PA were both associated with increased PA and decreased sedentary behavior. However, among students who lived in neighborhoods that were not safe for PA, a positive attitude toward PA was not associated with increased DPA or decreased sedentary behavior and was less strongly associated with VPA and MSA. Efforts to increase PA among youth should promote a positive attitude toward PA among youth and encourage adult family members to support their efforts to be active. Policies that promote safe neighborhoods may work synergistically with a positive attitude toward PA to increase participation in PA and decrease sedentary behaviors.

    This study examined cross-cultural differences in personal and behavioral determinants of vigorous-intensity and moderate-intensity physical activity (PA) among college students living in distinctly different cultures, that is, the United States, Costa Rica, India, and South Korea. Participants of this study were recruited from randomly chosen public universities in the 4 countries during the 2006-2007 academic year. A total of 4685 students participated in the study (response rate 90%). Vigorous-intensity PA was measured by asking on how many of the past 7 days the participants participated in PA for at least 20 minutes that made them sweat or breathe hard. For moderate-intensity PA, participants were asked on how many of the past 7 days they participated in PA for at least 30 minutes that did not make them sweat or breathe hard. Findings indicate that whereas perceived overweight and fruit and vegetable consumption are relatively culture-free predictors of PA, gender and TV/video watching are culture-specific predictors. Binge drinking was not predictive of meeting the vigorous-intensity and moderate-intensity PA guidelines in any of the 4 countries. PMID:19661101

    2013-01-01

    Background While physical activity in individuals tends to decline steadily with age, there are certain periods where this decline occurs more rapidly, such as during early adulthood. Interventions aimed at attenuating the declines in physical activity during this transition period appear warranted. Objective The purpose of the study was to test the feasibility and efficacy of a theoretically informed, website-delivered physical activity intervention aimed at students entering university. Methods Using a quasi-experimental design, 65 participants (44 females; mean age 18.51, SD 0.91) were assigned to either an intervention (receiving website access plus weekly prompts) or comparison condition (receiving unprompted website access only), completing questionnaires at baseline and follow-up 8 weeks later. The intervention website, “Active Transition”, was specifically designed to target students’ physical activity cognitions and self-regulatory skills. Results Intervention usage was low, with only 47% (18/38) of participants assigned to the intervention condition logging into the website 2 or more times. Among the broader student sample, there were significant declines in students’ physical activity behaviors (F 1,63=18.10, P<.001), attitudes (F 1,62=55.19, P<.001), and perceived behavioral control (F 1,62 =17.56, P<.001). In comparisons between intervention users (29/65, individuals logging in 2 or more times) and non-users (36/65, individuals logging in once or not at all), there was a significant interaction effect for intervention usage and time on perceived behavioral control (F 1,62=5.13, P=.03). Conclusions Poor intervention usage suggests that future efforts need to incorporate innovative strategies to increase intervention uptake and better engage the student population. The findings, however, suggest that a website-delivered intervention aimed at this critical life stage may have positive impact on students’ physical activity cognitions. Future

  2. Analyzing phosphorylation-dependent regulation of subcellular localization and transcriptional activity of transcriptional coactivator NT-PGC-1α.

    2013-01-01

    Peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) is a nuclear transcriptional coactivator that regulates the genes involved in energy metabolism. Recent evidence has been provided that alternative splicing of PPARGC1A gene produces a functional but predominantly cytosolic isoform of PGC-1α (NT-PGC-1α). We have demonstrated that transcriptional coactivation capacity of NT-PGC-1α is directly correlated with its nuclear localization in a PKA phosphorylation-dependent manner. In this chapter, we describe quantitative imaging analysis methods that are developed to measure the relative fluorescence intensity of the protein of interest in the nucleus and cytoplasm in a single cell and the frequency distribution of nuclear/cytoplasmic intensity ratios in the population of cells, respectively. This chapter also describes transient cotransfection and dual-luciferase reporter gene assay that examine the ability of coactivators to activate the transcriptional activity of transcription factors.

    A broad series of fully characterized, well-defined silica-supported W metathesis catalysts with the general formula [(≡SiO)W(═NAr)(═CHCMe2R)(X)] (Ar = 2,6-iPr2C6H3 (AriPr), 2,6-Cl2C6H3 (ArCl), 2-CF3C6H4 (ArCF3), and C6F5 (ArF5); X = OC(CF3)3 (OtBuF9), OCMe(CF3)2 (OtBuF6), OtBu, OSi(OtBu)3, 2,5-dimethylpyrrolyl (Me2Pyr) and R = Me or Ph) was prepared by grafting bis-X substituted complexes [W(NAr)(═CHCMe2R)(X)2] on silica partially dehydroxylated at 700 °C (SiO2-(700)), and their activity was evaluated with the goal to obtain detailed structure-activity relationships. Quantitative influence of the ligand set on the activity (turnover frequency, TOF) in self-metathesis of cis-4-nonene was investigated using multivariate linear regression analysis tools. The TOF of these catalysts (activity) can be well predicted from simple steric and electronic parameters of the parent protonated ligands; it is described by the mutual contribution of the NBO charge of the nitrogen or the IR intensity of the symmetric N-H stretch of the ArNH2, corresponding to the imido ligand, together with the Sterimol B5 and pKa of HX, representing the X ligand. This quantitative and predictive structure-activity relationship analysis of well-defined heterogeneous catalysts shows that high activity is associated with the combination of X and NAr ligands of opposite electronic character and paves the way toward rational development of metathesis catalysts.

[Subjects and Methods] A cross-sectional survey of 688 college students (285 men and 403 women) in Korea was conducted using a self-reported questionnaire. [Results] There was a significant difference in the level of physical activity between male and female students. The significant predictors of physical activity for male students were physical activity goals, physical activity self-efficacy, and sitting time. Meanwhile, those for female students were perceived weight, physical activity goal, physical activity outcome expectations, and sitting time. [Conclusion] Sex differences should be considered when developing interventions to increase physical activity. PMID:26180293

  15. Bacterial community structure and activity of sulfate reducing bacteria in a membrane aerated biofilm analyzed by microsensor and molecular techniques.

    PubMed

    Liu, Hong; Tan, Shuying; Sheng, Zhiya; Liu, Yang; Yu, Tong

    2014-11-01

    The activities and vertical spatial distribution of sulfate reducing bacteria (SRB) in an oxygen (O2 )-based membrane aerated biofilm (MAB) were investigated using microsensor (O2 and H2 S) measurements and molecular techniques (polymerase chain reaction-denaturing gradient gel electrophoresis [PCR-DGGE] and fluorescence in situ hybridization [FISH]). The O2 concentration profile revealed that O2 penetrated from the bottom (substratum) of the gas permeable membrane, and was gradually consumed within the biofilm until it was completely depleted near the biofilm/bulk liquid interface, indicating oxic and anoxic zone in the MAB. The H2 S concentration profile showed that H2 S production was found in the upper 285 µm of the biofilm, indicating a high activity of SRB in this region. The results from DGGE of the PCR-amplified dissimilatory sulfite reductase subunit B (dsrB) gene and FISH showed an uneven spatial distribution of SRB. The maximum SRB biomass was located in the upper biofilm. The information from the molecular analysis can be supplemented with that from microsensor measurements to better understand the microbial community and activity of SRB in the MAB.

    Berry, Stacy Jane

    considered as significant as the academic merit. The qualitative data substantiated the achievement success and revealed a positive relationship between a student centered learning environment and attitudes regarding learning geology. Our findings indicated a positive trend favoring active learning instructional practices, particularly methods that emphasize independent and active thinking, and analyzing of data. Of particular interest was the correlation between the amount of student ownership in an activity and students' attitude toward authenticity and application in learning. Students' perceptions and attitudes provided depth in program evaluation and helped in identifying which components used in teaching methodologies were the most effective towards learning. Although the exigencies of high enrollment introductory courses set limits for this study, the outcomes support the positive influence that active learning has on achievement performance in a high enrollment, introductory Geology course.
