The transition zone (TZ) of the root apex is the perception site of Al toxicity. Here, we show that exposure of Arabidopsis thaliana roots to Al induces a localized enhancement of auxin signaling in the root-apex TZ that is dependent on TAA1, which encodes a Trp aminotransferase and regulates auxin biosynthesis. TAA1 is specifically upregulated in the root-apex TZ in response to Al treatment, thus mediating local auxin biosynthesis and inhibition of root growth. The TAA1-regulated local auxin biosynthesis in the root-apex TZ in response to Al stress is dependent on ethylene, as revealed by manipulating ethylene homeostasis via the precursor of ethylene biosynthesis 1-aminocyclopropane-1-carboxylic acid, the inhibitor of ethylene biosynthesis aminoethoxyvinylglycine, or mutant analysis. In response to Al stress, ethylene signaling locally upregulates TAA1 expression and thus auxin responses in the TZ and results in auxin-regulated root growth inhibition through a number of auxin response factors (ARFs). In particular, ARF10 and ARF16 are important in the regulation of cell wall modification-related genes. Our study suggests a mechanism underlying how environmental cues affect root growth plasticity through influencing local auxin biosynthesis and signaling. © 2014 American Society of Plant Biologists.

The present study aimed to explore the neural correlates underlying the effects of idea evaluation on idea generation in creative thinking. Participants were required to generate original uses of conventional objects (alternative uses task) during EEG recording. A reflection task (mentally evaluating the generated ideas) or a distraction task (object characteristics task) was inserted into the course of idea generation. Behavioral results revealed that participants generated ideas with higher originality after evaluating the generated ideas than after performing the distraction task. The EEG results revealed that idea evaluation was accompanied with upper alpha (10-13 Hz) synchronization, most prominent at frontal cortical sites. Moreover, upper alpha activity in frontal cortices during idea generation was enhanced after idea evaluation. These findings indicate that idea evaluation may elicit a state of heightened internal attention or top-down activity that facilitates efficient retrieval and integration of internal memory representations.

The incidence of Hb Paksé (codon 142, TAA>TAT, α2) might have been underestimated due to misidentifying some cases as Hb Constant Spring (Hb CS, codon 142, TAA>CAA, α2) since both abnormal hemoglobins (Hbs) migrate to the same position on Hb electrophoresis or chromatography. Multiplex asymmetric allele-specific polymerase chain reaction (PCR) for identification of Hb CS and Hb Paksé, and a real-time PCR (ReTi-PCR) with SYBR Green1 high resolution melting (HRM) analysis, for detection of the α-thalassemia-1 (α-thal-1) Southeast Asian (- -(SEA)/) type deletion, were performed on 114 blood samples collected from subjects who lived in northern Thailand. These samples were previously identified as carrying Hb CS by capillary electrophoresis (CE) or high performance liquid chromatography (HPLC). Five out of 114 (4.4%) samples were found to carry Hb Paksé with four different genotypes including Hb Paksé trait, compound Hb CS/Hb Paksé, Hb H-Hb Paksé disease and Hb H-Hb Paksé-Hb E disease. These results suggested that Hb Paksé and its various combinations can be misidentified as Hb CS. Although the clinical symptoms of Hb Paksé and Hb CS are similar, to prevent erroneous epidemiological data on Hb CS as well as underestimating the prevalence of Hb Paksé in northern Thailand, DNA analysis is recommended to be performed in all cases when peaks of Hb CS/Hb Paksé are detected on CE or HPLC.

Hb Constant Spring [Hb CS, α142, Term→Gln, TAA>CAA (α2)] is a nondeletional form of α-thalassemia (α-thal) that is most prevalent in Southern Chinese and Southeast Asian populations. We previously found that Hb CS trait could efficiently be screened using Sebia Capillarys2. In this study, we report that Hb CS heterozygotes combined with β-thal could not be detected by the Sebia Capillarys2 method due to the very small amount of Hb CS.

That's a good idea, but let's keep thinking! Can we prevent our initial ideas from being forgotten as a consequence of thinking of new ideas?

Four experiments examined participants' ability to remember their own ideas in a modified Alternative Uses Task. Participants were asked to generate uses for objects, and on half of the trials participants were then asked to think of more uses. Memory for the initial uses they generated was then tested via a cued-recall task. Results demonstrated that participants forgot their initial uses as a consequence of thinking of new uses (referred to as the thinking-induced forgetting effect), and this effect persisted even when participants chose the subset of uses they thought were the most creative and to be remembered. The only scenario in which uses were protected from forgetting was when they were required to use their uses as hints for generating more ideas. Together, these findings demonstrate that one's own ideas are susceptible to forgetting when additional ideas must be generated, indicating that thinking is a modifier of memory despite one's motivation to preserve their ideas.

The IDEAS**2 computing environment

This document presents block diagrams of the IDEAS**2 computing environment. IDEAS**2 is the computing environment selected for system engineering (design and analysis) by the Center for Space Construction (CSC) at the University of Colorado (UCB). It is intended to support integration and analysis of any engineering system and at any level of development, from Pre-Phase A conceptual studies to fully mature Phase C/D projects. The University of Colorado (through the Center for Space Construction) has joined the Structural Dynamics Research Corporation (SDRC) University Consortium which makes available unlimited software licenses for instructional purposes. In addition to providing the backbone for the implementation of the IDEAS**2 computing environment, I-DEAS can be used as a stand-alone product for undergraduate CAD/CAE instruction. Presently, SDRC is in the process of releasing I-DEAS level 5.0 which represents a substantial improvement in both the user interface and graphic processing capabilities. IDEAS**2 will be immediately useful for a number of current programs within CSC (such as DYCAM and the 'interruptability problem'). In the future, the following expansions of the basic IDEAS**2 program will be pursued, consistent with the overall objectives of the Center and of the College: upgrade I-DEAS and IDEAS**2 to level 5.0; create new analytical programs for applications not limited to orbital platforms; research the semantic organization of engineering databases; and create an 'interoperability' testbed.

Temperature-tunable Fano resonance induced by strong Weyl fermion-phonon coupling in TaAs

Strong coupling between discrete phonon and continuous electron-hole pair excitations can give rise to a pronounced asymmetry in the phonon line shape, known as the Fano resonance. We present infrared spectroscopic studies on the recently discovered Weyl semimetal TaAs at different temperatures. Our experimental results reveal strong coupling between an infrared-active A1 phonon and electronic transitions near the Weyl points (Weyl fermions), as evidenced by the conspicuous asymmetry in the phonon line shape. More interestingly, the phonon line shape can be continuously tuned by temperature, which we demonstrate to arise from the suppression of the electronic transitions near the Weyl points due to the decreasing occupation of electronic states below the Fermi level with increasing temperature, as well as Pauli blocking caused by thermally excited electrons above the Fermi level. Supported by LANL LDRD and LANL-UCRP programs.

Where do new research questions come from? This is at best only partially taught in courses or textbooks about clinical or epidemiological research. Methods are taught under the assumption that a researcher already knows the research question and knows which methods will fit that question. Similarly, the real complexity of the thought processes that lead to a scientific undertaking is almost never described in published papers. In this paper, we first discuss how to get an idea that is worth researching. We describe sources of new ideas and how to foster a creative attitude by "cultivating your thoughts". Only a few of these ideas will make it into a study. Next, we describe how to sharpen and focus a research question so that a study becomes feasible and a valid test of the underlying idea. To do this, the idea needs to be "pruned". Pruning a research question means cutting away anything that is unnecessary, so that only the essence remains. This includes determining both the latent and the stated objectives, specific pruning questions, and the use of specific schemes to structure reasoning. After this, the following steps include preparation of a brief protocol, conduct of a pilot study, and writing a draft of the paper including draft tables. Then you are ready to carry out your research.

Phase transition in the quantum limit of the Weyl semimetal TaAs

NASA Astrophysics Data System (ADS)

Ramshaw, Brad

Under extreme magnetic fields, electrons in a metal are confined to a single highly-degenerate quantum state -a regime known as the quantum limit. This state is unstable to the formation of new states of matter, such as the fractional quantum Hall effect in two dimensions. The fate of 3D metals in the quantum limit, on the other hand, has been relatively unexplored. The discovery of monopnictide Weyl semimetals has renewed interest in the high-field properties of 3D electrons, particularly those with linear dispersions. Several difficulties in determining the high-field properties have arisen, including the highly anisotropic nature of the magnetoresistance, and the presence of trivial (parabolic) Fermi pockets that cloud the underlying behaviour of Weyl pockets. We use magnetic fields up to 90 Tesla to put the Weyl semimetal TaAs into its extreme quantum limit, isolating its linear 0th Landau level from the rest of the electronic spectrum. We find that a gap opens in the conductivity parallel to the magnetic field above 70 Tesla, and also find an abrupt reversal in the field-evolution of the sound velocity at the same magnetic field, suggesting a thermodynamic phase transition to a new state of matter.

Decades of problem solving and creativity research have converged to show that the ability to generate new and useful ideas can be blocked or impeded by intuitive biases leading to mental fixations. The present study aimed at investigating the neural bases of the processes involved in overcoming fixation effects during creative idea generation. Using the AU task adapted for EEG recording, we examined whether participant's ability to provide original ideas was related to alpha power changes in both the frontal and temporo-parietal regions. Critically, for half of the presented objects, the classical use of the object was primed orally, and a picture of the classical use was presented visually to increase functional fixedness (Fixation Priming condition). For the other half, only the name of the object and a picture of the object was provided to the participants (control condition). As expected, priming the classical use of an object before the generation of creative alternative uses of the object impeded participants' performances in terms of remoteness. In the control condition, while the frontal alpha synchronization was maintained across all successive time windows in participants with high remoteness scores, the frontal alpha synchronization decreased in participants with low remoteness scores. In the Fixation Priming condition, in which functional fixedness was maximal, both participants with high and low remoteness scores maintained frontal alpha synchronization throughout the period preceding their answer. Whereas participants with high remoteness scores maintained alpha synchronization in the temporo-parietal regions throughout the creative idea generation period, participants with low remoteness scores displayed alpha desynchronization in the same regions during this period. We speculate that individuals with high remoteness scores might generate more creative ideas than individuals with low remoteness scores because they rely more on internal semantic

Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs

Strong coupling between discrete phonon and continuous electron–hole pair excitations can induce a pronounced asymmetry in the phonon line shape, known as the Fano resonance. This effect has been observed in various systems. We reveal explicit evidence for strong coupling between an infrared-active phonon and electronic transitions near the Weyl points through the observation of a Fano resonance in the Weyl semimetal TaAs. The resulting asymmetry in the phonon line shape, conspicuous at low temperatures, diminishes continuously with increasing temperature. Furthermore, this behaviour originates from the suppression of electronic transitions near the Weyl points due to the decreasing occupation ofmore » electronic states below the Fermi level (EF) with increasing temperature, as well as Pauli blocking caused by thermally excited electrons above EF. These findings not only elucidate the mechanism governing the tunable Fano resonance but also open a route for exploring exotic physical phenomena through phonon properties in Weyl semimetals.« less

Strong Intrinsic Spin Hall Effect in the TaAs Family of Weyl Semimetals

NASA Astrophysics Data System (ADS)

Sun, Yan; Zhang, Yang; Felser, Claudia; Yan, Binghai

2016-09-01

Since their discovery, topological insulators are expected to be ideal spintronic materials owing to the spin currents carried by surface states with spin-momentum locking. However, the bulk doping problem remains an obstacle that hinders such an application. In this work, we predict that a newly discovered family of topological materials, the Weyl semimetals, exhibits a large intrinsic spin Hall effect that can be utilized to generate and detect spin currents. Our ab initio calculations reveal a large spin Hall conductivity in the TaAs family of Weyl materials. Considering the low charge conductivity of semimetals, Weyl semimetals are believed to present a larger spin Hall angle (the ratio of the spin Hall conductivity over the charge conductivity) than that of conventional spin Hall systems such as the 4 d and 5 d transition metals. The spin Hall effect originates intrinsically from the bulk band structure of Weyl semimetals, which exhibit a large Berry curvature and spin-orbit coupling, so the bulk carrier problem in the topological insulators is naturally avoided. Our work not only paves the way for employing Weyl semimetals in spintronics, but also proposes a new guideline for searching for the spin Hall effect in various topological materials.

Whose idea was that? Source monitoring for idea ownership following elaboration.

PubMed

Stark, Louisa-Jayne; Perfect, Timothy J

2007-10-01

Unconscious plagiarism (UP) occurs when an individual claims a previously experienced idea as their own. Previous studies have explored the cognitive precursors of such errors by manipulating the ways that ideas are thought about between initial idea exposure and later test. While imagining other's ideas does not increase rates of UP relative to control on either a recall-own or generate-new task, improving others' ideas substantially increases such errors in the recall-own task. This study explored the effects of elaboration on rates of UP when a source-monitoring test replaced the recall-own test. Plagiarism was again observed following idea improvement but not idea imagery even though participants engaged explicit source evaluation. Thus the probability of plagiarising another's idea appears linked to the generative nature of the idea processing performed.

Idea-box is an open source online app/website used to collect and surface ideas from members of an organization, or the public in general. Using the app, users login, view a request or challenge for new ideas, can submit their own ideas and/or view, comment and vote on other previously submitted ideas. Initially we will start with three idea request or “challenges” as listed below. The first will be run prior to the Summit to help generate additional challenges that might be added for the summit depending on the results. Initial Idea Challenges:1. (Prior to summit) If you could ask a large group of Saint Louis River focused scientist, stakeholders, managers, politicians and the public a question about the SLR, what would you ask?2. How might we better engage students and educators with the Saint Louis River?3. How might we employ citizen science for the Saint Louis River?The Idea-box app will be available for users two weeks before the Saint Louis Summit. We will e-mail previous summit participants and others an invitation to participate in “The Saint Louis River Idea-Slam” with clear instruction on how to proceed. During the morning of the first day at the Saint Louis Summit we will make a brief announcement about the Idea-Slam (< 2min.), and invite everyone to participate.

Groups of young idea people come to eat, drink, and talk about new ideas that old idea people are working on to change the world for the better. The ideas may fix our body and mind, make our lives easier or harder, and more. The young idea people lead, learn, listen and act, so they can become old idea people. The young idea people scare the old idea people because their ideas are different. And, sometimes, the young idea people have new ideas that the old idea people have not thought about. When this happens it makes the old idea people happy and better at their work. The old idea people get to go places and share their ideas around the world. They make good money and have fun lives. They write about their work and can be well known, or not. The young idea people learn from the old idea people how they can be like them. Together the young and old idea people build things and talk about crazy ideas that may come to be. Sometimes the old idea people talk too much and don't listen. They use big words that can be hard to understand. But, the young idea people help them learn to use known words so everyone learns. We know the young idea people learn and grow from this act and they grow happier about their life. We also know that the old idea people get happy that the young idea people are so bright.

Exploring Korean young children's ideas about living things

NASA Astrophysics Data System (ADS)

Kwon, Young Re

This qualitative study explored concepts of living things that five- and six-year-old Korean children held prior to formal instructional interventions and how their concepts were changed and developed over one semester in a kindergarten classroom. Six focal children in a class of 30 were interviewed in two phases and their hands-on classroom activities and teacher-children interactions were observed. The teacher's journal was also used to gather data. As the study was conducted, a number of alternative concepts related to the children's perceptions of living things were identified and described. The researcher interviewed the children to determine their initial ideas, using an informal interview guide; they responded whether certain objects were living or not, and how they told if the particular objects were living or not. The classroom activities were also observed in large/small groups and individually. An assisting observer viewed the classroom activities and simultaneously recorded science-related teacher-children interactions and the children's hands-on activities. Later the researcher made a transcription of the observer's notes. The data were also collected from the teacher's journal, in which she recorded everyday classroom activities and reflected on teaching and learning. Finally, after 8 weeks of the 16-week instructional intervention, the researcher interviewed the children, using a formal interview guide, as to how their concepts of living things had changed and developed. The researcher interviewed the children as to whether particular objects were plants or animals, neither or both, and the criteria they used to decide. The study showed that the kindergarten children had solid and unique ideas based on their everyday experience with living and non-living things prior to the formal instructional inventions. In the classroom activities, the children showed that they rejected or changed several of their own concepts of living things. The instructional

Background The dementia diagnosis gap in sub-Saharan Africa (SSA) is large, partly due to difficulties in assessing function, an essential step in diagnosis. Objectives As part of the Identification and Intervention for Dementia in Elderly Africans (IDEA) study, to develop, pilot, and validate an Instrumental Activities of Daily Living (IADL) questionnaire for use in a rural Tanzanian population to assist in the identification of people with dementia alongside cognitive screening. Design The questionnaire was developed at a workshop for rural primary healthcare workers, based on culturally appropriate roles and usual activities of elderly people in this community. It was piloted in 52 individuals under follow-up from a dementia prevalence study. Validation subsequently took place during a community dementia-screening programme. Construct validation against gold standard clinical dementia diagnosis using DSM-IV criteria was carried out on a stratified sample of the cohort and validity assessed using area under the receiver operating characteristic (AUROC) curve analysis. Results An 11-item questionnaire (IDEA-IADL) was developed after pilot testing. During formal validation on 130 community-dwelling elderly people who presented for screening, the AUROC curve was 0.896 for DSM-IV dementia when used in isolation and 0.937 when used in conjunction with the IDEA cognitive screen, previously validated in Tanzania. The internal consistency was 0.959. Performance on the IDEA-IADL was not biased with regard to age, gender or education level. Conclusions The IDEA-IADL questionnaire appears to be a useful aid to dementia screening in this setting. Further validation in other healthcare settings in SSA is required. PMID:25537940

After the interest in surgical research, developing the research idea is of fundamental importance because without it we can not have research. Where do the research ideas come from then? Is there any better way to improve our ability to generate research ideas? Where do they come from? What are the factors that stimulate the research idea? Anything we do in and out of medicine or surgery should be the force that will maintain our mind occupied on our future research ideas. From events in the clinical arena to discussions in formal rounds or informal meetings should be the origin of our thinking in research. So, the generation of research ideas come from any place and we should be aware of it. We could be successful in research if we could produce and accumulate the ideas as they frequently present to us in our professional or daily life. The research environment could help us in securing the presence and evolution of the idea. Be aware of changes and future developments and be ready to admit and grow the research idea that could be presented to you during the practice of medicine.

The selection of creative ideas after individual idea generation: choosing between creativity and impact.

PubMed

Rietzschel, Eric F; Nijstad, Bernard A; Stroebe, Wolfgang

2010-02-01

It is commonly assumed that successful innovation depends on creative idea generation: the more ideas are generated, the higher the probability of selecting a very good idea should be. However, research has shown that people do not perform optimally at idea selection and that ideational output may not contribute much to creative idea selection. The present studies aim to explain this phenomenon. We identified the strong tendency of our participants to select feasible and desirable ideas, at the cost of originality, as the main reason for their poor selection performance. Two manipulations of participants' processing of the available ideas (exclusion instructions and quality ratings) had no effect on selection effectiveness. In contrast, explicitly instructing participants to select creative or original ideas did improve selection effectiveness with regard to idea originality, but at the same time decreased participants' satisfaction and the rated effectiveness of chosen ideas. Results are discussed in relation to an effectiveness-originality trade off.

[Comparative analysis of electroencephalographic tests of alpha activity attenuation in evaluation of involuntary falling asleep in healthy adults].

Decrease of daily alertness is a common cause of accidents in the work place, especially traffic accidents. Therefore, an increasing interest exists to determine reliable indicators of a tendency to fall asleep involuntarily. To determine an optimal electroencephalographic (EEG) indicator of an involuntary tendency to fall asleep, we performed a study on neurologically healthy subjects, after one night of sleep deprivation. Total sleep deprivation was aimed at increasing daily sleepiness in healthy subjects, providing us with an opportunity to test different methods of evaluation. We applied a visual analogue scale for sleepiness (VASS), EEG registration with the specific test of alpha activity attenuation (TAA) in 87 healthy subjects. The test was perfomed in a standard way (sTAA) as well as in accordance with new modifications related to changes of EEG filter width in the range from 5 to 32 Hz (mTAA). After sleep deprivation, we observed involuntary falling asleep in 54 subjects. The comparison of VASS results showed no differences, contrary to a more objective TAA. Between two variants of TAA, the modified test provided us with a better prediction for subjects who would fall asleep involuntarily. The application of a more objective EEG test in evaluation of daily alertness represents the optimal method of testing. Modified TAA attracts special attention, offering a simple solution for reliable testing of decreased daily alertness in medical services related to professional aircraft personnel.

The Effect of 3-Thiopheneacetic Acid in the Polymerization of a Conductive Electrotextile for Use in Biosensor Development

PubMed Central

McGraw, Shannon K.; Alocilja, Evangelyn; Senecal, Andre; Senecal, Kris

2013-01-01

Investigations were conducted to develop an electrotextile using a nonwoven polypropylene fiber platform conformally coated in a conductive, functionalized copolymer of polypyrrole and 3-thiopheneacetic acid (3TAA). The objectives of this study were to determine: (1) if the inclusion of 3TAA in the polymerization process would have an effect on the availability of binding sites in the high-surface area electrotextile for biorecognition elements and (2) how the increase in the concentration of 3TAA would affect the physical characteristics of the coating, resistivity of the sample and availability of binding sites. It was found that the addition of 3TAA to the polymerization process resulted in an increase in the size of the polypyrrole coating, as well as the material resistivity and available binding sites for biorecognition elements. These factors were used to determine which of the tested concentrations was best for biosensor development. A polymer coated membrane sample containing a concentration within the range of 10–50 mg/mL of 3TAA was selected as the best for future biosensor work. PMID:25586259

Altered microRNA expression is implicated in cardiovascular diseases. Our objective was to determine microRNA signatures in thoracic aortic aneurysms (TAAs) and abdominal aortic aneurysms (AAAs) compared with control non-aneurysmal aortic specimens. We evaluated the expression of fifteen selected microRNA in human TAA and AAA operative specimens compared to controls. We observed significant upregulation of miR-221 and downregulation of miR-1 and -133 in TAA specimens. In contrast, upregulation of miR-146a and downregulation of miR-145 and -331-3p were found only for AAA specimens. Upregulation of miR-126 and -486-5p and downregulation of miR-30c-2*, -155, and -204 were observed in specimens of TAAs and AAAs. The data reveal microRNA expression signatures unique to aneurysm location and common to both thoracic and abdominal pathologies. Thus, changes in miR-1, -29a, -133a, and -221 are involved in TAAs and miR-145, -146, and -331-3p impact AAAs. This work validates prior studies on microRNA expression in aneurysmal diseases.

More mind wandering, fewer original ideas: be not distracted during creative idea generation.

PubMed

Hao, Ning; Wu, Mengxia; Runco, Mark A; Pina, Jeremy

2015-10-01

Several studies suggest that mind wandering (MW) benefits creativity when the MW occurs in the incubation period of creative problem solving. The aim of present study was to examine the effects of MW that occurs in the course of creative idea generation. Participants received an Alternative Uses Task (AUT) and were asked to generate ideas for 20min. Their MW frequencies as time passed were measured by means of probe-caught MW. Comparisons of the AUT performances of high and low MW groups revealed that greater MW was associated with lower fluency and originality scores on the AUT. Furthermore, the high MW group showed greater MW as time passed, while the low MW group's MW was steady during the course of idea generation. Accordingly, the originality of idea generation decreased with time passing for the high MW group but was steady for the low MW group. The findings suggest that the MW during the course of creative idea generation is negatively related to creativity, perhaps because the control processes involved in idea generation are impaired by the mind wandering.

Why do I always have the best ideas? The role of idea quality in unconscious plagiarism.

PubMed

Perfect, Timothy J; Stark, Louisa-Jayne

2008-05-01

Groups of individuals often work together to generate solutions to a problem. Subsequently, one member of the group can plagiarise another either by recalling that person's idea as their own (recall-own plagiarism), or by generating a novel solution that duplicates a previous idea (generate-new plagiarism). The current study examines the extent to which these forms of plagiarism are influenced by the quality of the ideas. Groups of participants initially generated ideas, prior to an elaboration phase in which idea quality was manipulated in two ways: participants received feedback on the quality of the ideas as rated by independent judges, and they generated improvements to a subset of the ideas. Unconscious plagiarism was measured in recall-own and generate-new tasks. For recall, idea improvement led to increased plagiarism, while for the generate-new task, the independent ratings influenced plagiarism. These data indicate that different source-judgement processes underlie the two forms of plagiarism, neither of which can be reduced simply to memory strength.

Object-oriented productivity metrics

NASA Technical Reports Server (NTRS)

Connell, John L.; Eller, Nancy

1992-01-01

Software productivity metrics are useful for sizing and costing proposed software and for measuring development productivity. Estimating and measuring source lines of code (SLOC) has proven to be a bad idea because it encourages writing more lines of code and using lower level languages. Function Point Analysis is an improved software metric system, but it is not compatible with newer rapid prototyping and object-oriented approaches to software development. A process is presented here for counting object-oriented effort points, based on a preliminary object-oriented analysis. It is proposed that this approach is compatible with object-oriented analysis, design, programming, and rapid prototyping. Statistics gathered on actual projects are presented to validate the approach.

A collaborative approach was used to ascertain an appropriate stimulus for the patients to remember their stroke-specific education. The stroke education had to stand out amidst the myriad of papers and folders patients are bombarded with in the hospital. The team came up with the simple idea of using a bright red folder. When the patients were called, the call center would prompt the patient by saying, "The stroke education was given to you in a bright red folder." Before the implementation of the red folders, only 81.5% of the patients remembered receiving stroke education. After the implementation of the red folders, 96.8% remembered receiving stroke education. The principle of Occam's razor proved to be correct in our study. A very simple idea such as changing the color of the folders to bright red proved to have very meaningful results.

The distinction between key ideas in teaching school physics and key ideas in the discipline of physics

NASA Astrophysics Data System (ADS)

Deng, Zongyi

2001-05-01

The distinction between key ideas in teaching a high school science and key ideas in the corresponding discipline of science has been largely ignored in scholarly discourse about what science teachers should teach and about what they should know. This article clarifies this distinction through exploring how and why key ideas in teaching high school physics differ from key ideas in the discipline of physics. Its theoretical underpinnings include Dewey's (1902/1990) distinction between the psychological and the logical and Harré's (1986) epistemology of science. It analyzes how and why the key ideas in teaching color, the speed of light, and light interference at the high school level differ from the key ideas at the disciplinary level. The thesis is that key ideas in teaching high school physics can differ from key ideas in the discipline in some significant ways, and that the differences manifest Dewey's distinction. As a result, the article challenges the assumption of equating key ideas in teaching a high school science with key ideas in the corresponding discipline of science, and the assumption that having a college degree in science is sufficient to teach high school science. Furthermore, the article expands the concept of pedagogical content knowledge by arguing that key ideas in teaching high school physics constitute an essential component.

2008-01-01

Objective To explore 5-year-old girls’ ideas, concepts, and beliefs about dieting. Design Girls were asked to define dieting, to describe the behaviors dieting comprised, and were queried about links between dieting, weight control, and body shape. Parents completed questionnaires addressing family health history, demographics, and issues related to food, dieting, and weight control. Subjects/setting Participants were 197 girls aged 5 years and their parents. All girls lived with both biological parents, and were without food allergies or chronic medical problems. Statistical analyses performed For 5 open-ended questions related to dieting, girls were categorized as either having or not having ideas about dieting. These ideas, concepts, and beliefs were categorized, and logistic regression examined predictors of girls’ ideas about dieting. Results Depending on the question, from 34% to 65% of girls aged 5 years had ideas about dieting. Compared to girls whose mothers did not diet, girls whose mothers reported current or recent dieting were more than twice as likely to have ideas about dieting, suggesting that mothers’ dieting behavior is a source of young girls’ ideas, concepts, and beliefs about dieting. Among mothers, more than 90% reported recent dieting, and most reported use of both health-promoting and health-compromising dieting behaviors. Applications Women should be informed that weight control attempts may influence their young daughters’ emerging ideas, concepts, and beliefs about dieting. Mothers should be encouraged to use health-promoting rather than health-compromising weight control strategies, not only for their own well being, but to reduce the likelihood that daughters will incorporate health-compromising dieting behaviors into their concepts, ideas, and beliefs about dieting.

Selecting and perceiving multiple visual objects

PubMed Central

Xu, Yaoda; Chun, Marvin M.

2010-01-01

To explain how multiple visual objects are attended and perceived, we propose that our visual system first selects a fixed number of about four objects from a crowded scene based on their spatial information (object individuation) and then encode their details (object identification). We describe the involvement of the inferior intra-parietal sulcus (IPS) in object individuation and the superior IPS and higher visual areas in object identification. Our neural object-file theory synthesizes and extends existing ideas in visual cognition and is supported by behavioral and neuroimaging results. It provides a better understanding of the role of the different parietal areas in encoding visual objects and can explain various forms of capacity-limited processing in visual cognition such as working memory.

Karl Jaspers on the disease entity: Kantian ideas and Weberian ideal types.

PubMed

Walker, Chris

2014-09-01

Jaspers' nosology is indebted to Immanuel Kant's theory of knowledge. He drew the distinction of form and content from the Transcendental Analytic of Kant's Critique of Pure Reason. The distinction is universal to all knowledge, including psychopathology. Individual experience is constituted by a form or category of the Understanding to give a determinate or knowable object classified into the generic type of a real disease entity. The application of form and content is limited by the boundaries of experience. Beyond this boundary are wholes whose conception requires Ideas of reason drawn from the Transcendental Dialectic. Wholes are regulated by Ideas of reason to give an object or schema of the Idea collected into ideal types of an ideal typical disease entity. Jaspers drew ideal types from Max Weber's social theory. He anticipated that, as knowledge advanced, ideal typical disease entities would become real disease entities. By 1920, this had been the destiny of general paralysis as knowledge of its neuropathology, serology and microbiology emerged. As he presented the final edition of General Psychopathology in 1946, Jaspers was anticipating the transition of schizophrenia from ideal typical to real disease entity. Almost 70 years later, with knowledge of its aetiology still unclear, schizophrenia remains marooned as an ideal typical disease entity - still awaiting that crucial advance! © The Author(s) 2014.

How to pitch a brilliant idea.

PubMed

Elsbach, Kimberly D

2003-09-01

Coming up with creative ideas is easy; selling them to strangers is hard. Entrepreneurs, sales executives, and marketing managers often go to great lengths to demonstrate how their new concepts are practical and profitable--only to be rejected by corporate decision makers who don't seem to understand the value of the ideas. Why does this happen? Having studied Hollywood executives who assess screenplay pitches, the author says the person on the receiving end--the "catcher"--tends to gauge the pitcher's creativity as well as the proposal itself. An impression of the pitcher's ability to come up with workable ideas can quickly and permanently overshadow the catcher's feelings about an idea's worth. To determine whether these observations apply to business settings beyond Hollywood, the author attended product design, marketing, and venture-capital pitch sessions and conducted interviews with executives responsible for judging new ideas. The results in those environments were similar to her observations in Hollywood, she says. Catchers subconsciously categorize successful pitchers as showrunners (smooth and professional), artists (quirky and unpolished), or neophytes (inexperienced and naive). The research also reveals that catchers tend to respond well when they believe they are participating in an idea's development. As Oscar-winning writer, director, and producer Oliver Stone puts it, screen-writers pitching an idea should "pull back and project what he needs onto your idea in order to make the story whole for him." To become a successful pitcher, portray yourself as one of the three creative types and engage your catchers in the creative process. By finding ways to give your catchers a chance to shine, you sell yourself as a likable collaborator.

The Idea of Patents vs. the Idea of University.

PubMed

de Campos, Thana Cristina

2015-01-01

It is generally accepted that patents are a driving force for innovation through research and development. But the university's involvement in patenting is problematic as well. In particular, it is in tension with the idea of a university itself. If patents entail a restriction on the accessibility of the scientific knowledge that has been patented, and if the main purpose of universities is to produce and disseminate knowledge to the public, then, there is a tension: when universities patent their research innovations, they are making the scientific knowledge they produce less accessible to the public. The paper argues that university patenting contradicts the very idea of a university as an institution whose mission is fundamentally to disseminate the knowledge it produces to the public. The practice of university patenting involves an un-academic attitude thus: by inciting an attitude towards knowledge that is not consistent with the proper attitudes and goals of a university, university patenting hurts university's integrity.

Object-location memory in adults with autism spectrum disorder.

Ring, Melanie; Gaigg, Sebastian B; Bowler, Dermot M

2015-10-01

This study tested implicit and explicit spatial relational memory in Autism Spectrum Disorder (ASD). Participants were asked to study pictures of rooms and pictures of daily objects for which locations were highlighted in the rooms. Participants were later tested for their memory of the object locations either by being asked to place objects back into their original locations or into new locations. Proportions of times when participants choose the previously studied locations for the objects irrespective of the instruction were used to derive indices of explicit and implicit memory [process-dissociation procedure, Jacoby, 1991, 1998]. In addition, participants performed object and location recognition and source memory tasks where they were asked about which locations belonged to the objects and which objects to the locations. The data revealed difficulty for ASD individuals in actively retrieving object locations (explicit memory) but not in subconsciously remembering them (implicit memory). These difficulties cannot be explained by difficulties in memory for objects or locations per se (i.e., the difficulty pertains to object-location relations). Together these observations lend further support to the idea that ASD is characterised by relatively circumscribed difficulties in relational rather than item-specific memory processes and show that these difficulties extend to the domain of spatial information. They also lend further support to the idea that memory difficulties in ASD can be reduced when support is provided at test. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

What a great idea! Someone should evaluate that...

PubMed

Schmidt, David D

2016-06-01

How often, as clinicians, do we see a really clever idea implemented in the workplace? In rural health in particular, creative work-around solutions are relatively commonplace. However, the evaluation and promotion of these ideas is less so, and this leads to lost opportunities for perpetuating these clever ideas. This paper explores one rural clinician's experience of what can happen if, instead of appreciating and complementing a great idea, that step of evaluating the great idea is taken. A reflective narrative was created, beginning with a corridor conversation ('What a great idea! Someone should evaluate that...'), continuing through a formal research project and ending with the impact of that project and the way its findings were communicated and implemented. The narrative outlines the effect of evaluating one great idea at the individual, workplace, organisational, state and national levels. Clinicians are well placed to identify great ideas in practice. Making the decision to evaluate these ideas can lead to personal growth, professional discovery and organisational benefits. With motivation and organisational support, who knows where evaluation may lead?

What is "Object-Oriented Programming"?

NASA Astrophysics Data System (ADS)

Stroustrup, Bjarne

"Object-Oriented Programming" and "Data Abstraction" have become very common terms. Unfortunately, few people agree on what they mean. I will offer informal definitions that appear to make sense in the context of languages like Ada, C++, Modula-2, Simula67, and Smalltalk. The general idea is to equate "support for data abstraction" with the ability to define and use new types and equate "support for object-oriented programming" with the ability to express type hierarchies. Features necessary to support these programming styles in a general purpose programming language will be discussed. The presentation centers around C++ but is not limited to facilities provided by that language.

The creative brain in the figural domain: Distinct patterns of EEG alpha power during idea generation and idea elaboration.

PubMed

Rominger, Christian; Papousek, Ilona; Perchtold, Corinna M; Weber, Bernhard; Weiss, Elisabeth M; Fink, Andreas

2018-02-13

This study investigated EEG activity in the upper alpha band during the well-known Picture Completion Task of the Torrance Test of Creative Thinking (TTCT), a widely used creative ideation task in the figural domain. The application of a sophisticated computerized version of the TTCT facilitating the online assessment and digitalizing of participant's drawings allowed to separate two central stages of the creative ideation process (i.e., idea generation and idea elaboration). During idea generation, the participants' task was to generate an initial draft of an original and creative completion of the presented abstract lines and figures of the TTCT. During idea elaboration, the participants were required to mentally improve the originality of the initially generated idea/draft. Creative ideation in this figural task was generally associated with comparatively strong desynchronization of upper alpha power over parietal and occipital sites, indicating high visual/figural processing demands. Interestingly, the stage of idea elaboration was accompanied by a relative increase of upper alpha power at parietal and occipital sites compared to the stage of idea generation, indicating heightened top-down processing demands. Furthermore, task performance was associated with relative increases of upper alpha power at frontal sites and relative decreases at centro-temporal sites from the stage of idea generation to idea elaboration. This association suggests the importance of increased inhibitory control over stimulus-based bottom-up information and motor imagery in order to achieve more creative outputs. Taken together these findings add to the relevant literature in that they a) extend research on the relationship between EEG alpha activity and creativity to the figural domain, and b) support a multistage view of creative ideation, involving cognitive control and mental imagery as important components of creativity.

Secondary Students' Understanding of Basic Ideas of Special Relativity

NASA Astrophysics Data System (ADS)

Dimitriadi, Kyriaki; Halkia, Krystallia

2012-11-01

A major topic that has marked 'modern physics' is the theory of special relativity (TSR). The present work focuses on the possibility of teaching the basic ideas of the TSR to students at the upper secondary level in such a way that they are able to understand and learn the ideas. Its aim is to investigate students' learning processes towards the two axioms of the theory (the principle of relativity and the invariance of the speed of light) and their consequences (the relativity of simultaneity, time dilation and length contraction). Based on an analysis of physics college textbooks, on a review of the relevant bibliography and on a pilot study, a teaching and learning sequence consisting of five sessions was developed. To collect the data, experimental interviews (the so-called teaching experiment) were used. The teaching experiment may be viewed as a Piagetian clinical interview that is deliberately employed as a teaching and learning situation. The sample consisted of 40 10th grade students (aged 15-16). The data were collected by taping and transcribing the 'interviews', as well as from two open-ended questionnaires filled out by each student, one before and the other after the sessions. Methods of qualitative content analysis were applied. The results show that upper secondary education students are able to cope with the basic ideas of the TSR, but there are some difficulties caused by the following student conceptions: (a) there is an absolute frame of reference, (b) objects have fixed properties and (c) the way events happen is independent of what the observers perceive.

Background Patient adherence to medication regimens is critical in most chronic disease treatment plans. This study uses a patient-centered tablet app, “My Interventional Drug-Eluting Stent Educational App (MyIDEA).” This is an educational program designed to improve patient medication adherence. Objective Our goal is to describe the design, methodology, limitations, and results of the MyIDEA tablet app. We created a mobile technology-based patient education app to improve dual antiplatelet therapy adherence in patients who underwent a percutaneous coronary intervention and received a drug-eluting stent. Methods Patient advisers were involved in the development process of MyIDEA from the initial wireframe to the final launch of the product. The program was restructured and redesigned based on the patient advisers’ suggestions as well as those from multidisciplinary team members. To accommodate those with low health literacy, we modified the language and employed attractive color schemes to improve ease of use. We assumed that the target patient population may have little to no experience with electronic tablets, and therefore, we designed the interface to be as intuitive as possible. Results The MyIDEA app has been successfully deployed to a low-health-literate elderly patient population in the hospital setting. A total of 6 patients have interacted with MyIDEA for an average of 17.6 minutes/session. Conclusions Including patient advisers in the early phases of a mobile patient education development process is critical. A number of changes in text order, language, and color schemes occurred to improve ease of use. The MyIDEA program has been successfully deployed to a low-health-literate elderly patient population. Leveraging patient advisers throughout the development process helps to ensure implementation success. PMID:26139587

Ascending Aortic Aneurysm Is an Inherited Disease: A Contemporary Literature Review Based on Hill's Criteria of Specificity, Strength of Association, and Biological Coherence.

PubMed

Ahmad, Mirza Mujadil; Kiani, Immad Arif; Ammar, Khawaja Afzal; Ahmad, Mirza Nubair; Khandheria, Bijoy K; Paterick, Timothy E; Jain, Renuka; Tajik, A Jamil

There is growing evidence of a differential etiological basis for thoracic aortic aneurysms (TAA), with ascending (As) TAAs being genetically mediated and descending (Des) TAAs more strongly related to acquired pathologies. A comprehensive literature review of this hypothesis has not been carried out. We carried out a systematic literature review based on the latest guidelines on TAA endorsed by the American Heart Association. The etiologies were classified as genetic and inherited, the studies were tabulated accordingly, and Hill's epidemiological criteria of causality were applied. We found 38 studies addressing the etiology of TAAs. Out of these, 17 were about genetic causes, 9 about acquired causes, and 4 had information regarding both etiologies. Multiple genetic studies showed a strong association of As TAA with different genetic mutations. Contrary to commonly held beliefs, acquired causes, that is, dyslipidemia, diabetes, and atherosclerosis, were negatively associated with As TAA and positively associated with Des TAA. Hypertension was only associated with Des TAA and dissections (TAAD), not with As TAA. Multiple studies fulfilled the criteria of strength of association (n = 4), consistency (n = 9), specificity (n = 5), temporality (24), biological gradient (n = 3), plausibility (n = 38), biological coherence (n = 25), experiment (n = 4), and analogy (n = 6). Our literature review supports the hypothesis that As TAA is genetically mediated and Des TAA is predominantly an acquired pathology, and supports the argument for genetic testing in all cases of As TAA.

BACKGROUND/OBJECTIVE Orostachys japonicus A. Berger (Crassulaceae) has been used in traditional herbal medicines in Korea and other Asian countries to treat various diseases, including liver disorders. In the present study, the anti-fibrotic effects of O. japonicus extract (OJE) in cellular and experimental hepatofibrotic rat models were investigated. MATERIALS/METHODS An in vitro hepatic stellate cells (HSCs) system was used to estimate cell viability, cell cycle and apoptosis by MTT assay, flow cytometry, and Annexin V-FITC/PI staining techniques, respectively. In addition, thioacetamide (TAA)-induced liver fibrosis was established in Sprague Dawley rats. Briefly, animals were divided into five groups (n = 8): Control, TAA, OJE 10 (TAA with OJE 10 mg/kg), OJE 100 (TAA with OJE 100 mg/kg) and silymarin (TAA with Silymarin 50 mg/kg). Fibrosis was induced by treatment with TAA (200 mg/kg, i.p.) twice per week for 13 weeks, while OJE and silymarin were administered orally two times per week from week 7 to 13. The fibrotic related gene expression serum biomarkers glutathione and hydroxyproline were estimated by RT-PCR and spectrophotometry, respectively, using commercial kits. RESULTS OJE (0.5 and 0.1 mg/mL) and silymarin (0.05 mg/mL) treatment significantly (P < 0.01 and P < 0.001) induced apoptosis (16.95% and 27.48% for OJE and 25.87% for silymarin, respectively) in HSC-T6 cells when compared with the control group (9.09%). Further, rat primary HSCs showed changes in morphology in response to OJE 0.1 mg/mL treatment. In in vivo studies, OJE (10 and 100 mg/kg) treatment significantly ameliorated TAA-induced alterations in levels of serum biomarkers, fibrotic related gene expression, glutathione, and hydroxyproline (P < 0.05-P < 0.001) and rescued the histopathological changes. CONCLUSIONS OJE can be developed as a potential agent for the treatment of hepatofibrosis. PMID:29209457

There was not, they did not: May negation cause the negated ideas to be remembered as existing?

PubMed Central

2017-01-01

In this article we demonstrate that negation of ideas can have paradoxical effects, possibly leading the listener to believe that the negated ideas actually existed. In Experiment 1, participants listened to a description of a house, in which some objects were mentioned, some were negated, and some were not mentioned at all. When questioned about the existence of these objects a week later, the participants gave more false positives for items that were negated in the original material than for items that were not mentioned at all, an effect we call negation related false memories (NRFM). The NRFM effect was replicated again in Experiment 2 with a sample of five and six year-old children. Experiment 3 confirmed NRFM in the case of negated actions. The results are discussed in terms of retention hypothesis, as well as the theory that negation can activate a representation of an entity and behaviour. It is also indicated that future research is needed to ensure that it is indeed negation which caused false alarms, not merely mentioning an object. PMID:28448549

Stochastic evolution in populations of ideas

Nicole, Robin; Sollich, Peter; Galla, Tobias

2017-01-01

It is known that learning of players who interact in a repeated game can be interpreted as an evolutionary process in a population of ideas. These analogies have so far mostly been established in deterministic models, and memory loss in learning has been seen to act similarly to mutation in evolution. We here propose a representation of reinforcement learning as a stochastic process in finite ‘populations of ideas’. The resulting birth-death dynamics has absorbing states and allows for the extinction or fixation of ideas, marking a key difference to mutation-selection processes in finite populations. We characterize the outcome of evolution in populations of ideas for several classes of symmetric and asymmetric games.

Total ankle arthroplasty (TAA) provides an alternative to ankle fusion (AF). The purpose of this study is to (1) determine the extent of TAA regionalization, as well as examine the growth of TAA performed at high-, medium-, and low-volume New York State institutions and (2) compare this regionalization and growth with AF. The New York Statewide Planning and Research Cooperative System (SPARCS) administrative data were used to identify 737 primary TAA and 7453 AF from 2005 to 2014. The volume of TAA and AF surgery in New York State was mapped according to patient and hospital 3-digit zip code. The number of TAA per year grew 1500% (from 11 to 177) from 2005 to 2014, while there was a 35.6% reduction (from 895 to 576) in yearly AF procedures. TAA recipients were widely distributed throughout the state, while TAA procedures were regionalized to a few select metropolitan centers. AF procedures were performed more uniformly than TAA. The number of TAA has continued to increase at high- (15 to 91) and medium-volume (14 to 67) institutions where it has decreased at low-volume institutions (44 to 19). The increased utilization of TAA is attributed to relatively few high-volume centers located in major metropolitan centers. Level IV: well-designed case-control or cohort studies.

Quasilinear theory of plasma turbulence. Origins, ideas, and evolution of the method

NASA Astrophysics Data System (ADS)

Bakunin, O. G.

2018-01-01

The quasilinear method of describing weak plasma turbulence is one of the most important elements of current plasma physics research. Today, this method is not only a tool for solving individual problems but a full-fledged theory of general physical interest. The author's objective is to show how the early ideas of describing the wave-particle interactions in a plasma have evolved as a result of the rapid expansion of the research interests of turbulence and turbulent transport theorists.

Effects of Process and Outcome Accountability on Idea Generation.

Previous research on the effects of outcome and process accountability on decision making has neglected the preceding phase of idea generation. We conducted a 2 (outcome accountability: yes vs. no) × 2 (process accountability: yes vs. no) experiment (N = 147) to test the effects of accountability on quantity and quality of generated ideas in a product design task. Furthermore, we examined potential negative side effects of accountability (i.e., stress and lengthened decision making). We found that (a) outcome accountability had a negative effect on quantity of ideas and (b) process accountability extended the idea generation process. Furthermore, any type of accountability (c) had a negative effect on uniqueness of ideas, (d) did not affect the quality of the idea that was selected, and (e) increased stress. Moreover, the negative effect of accountability on uniqueness of ideas was mediated by stress.

Infectious and parasitic diseases cause massive health problems in the developing world. Research and development of drugs for diseases that mainly affect poor people in developing countries is limited. The advance market commitment (AMC) idea is an incentivising mechanism for research and development of drugs for neglected diseases. Discussion of the AMC idea is of renewed interest given the launch in June 2009 of the first AMC. This pilot AMC is designed to, among other things, test the idea for potential future applications. This paper is a critique of the AMC idea. It seeks to show that the idea has a hitherto unrecognised theoretical flaw that should make policy-makers and donors hesitant to embrace future applications of the idea.

2006-11-01

The innovation process is often more important than the original idea, particularly when the ultimate goal is to improve patient care through technologically advanced products. Many physicians have great ideas; unfortunately, many of these great ideas are never translated to patient care improvements because of a misunderstanding of "the next step." In many cases, the next step is a step backward to understand the real clinical problem: "the clinical need." With the clinical need in hand, the most efficient path to a product for improved patient care can then be derived. Often, the most efficient pathway involves an appreciation of many issues, including intellectual property, regulatory pathways, finance, and clinical trial strategies. The integration of these issues underlies innovation in biomedical technology.

Disordered speech and language deficits are well-documented in schizophrenia-spectrum disorders. Researchers often assess speech samples using manualized rating systems, though recently computerized language assessment methods have been used more frequently in the study of speech from people with schizophrenia. Most typically, these computerized assessments measure aspects of expressivity (i.e., pause durations, prosody) or use word-count technology; less attention has focused on similar methods that can capture more sophisticated aspects of linguistic complexity (e.g., idea density). The primary objective of the present study was to assess idea density - via a computerized measure - in the life-story narratives of people with schizophrenia (n=32) compared to a group of community control participants (n=15). In the schizophrenia group, we also examined associations between idea density, narrative qualities rated via a manualized measure, and psychiatric symptoms. Our findings indicate that idea density is diminished in individuals with schizophrenia compared to controls. Further, our results suggest that though people with schizophrenia with richer idea density tended to have more developed insight into illness, they also had higher levels of depression, anxiety, and avolition. Implications of these results and suggestions for future research are discussed. Copyright © 2016 Elsevier B.V. All rights reserved.

Ascending thoracic aortic aneurysms protect against myocardial infarctions.

PubMed

Chau, Katherine; Elefteriades, John A

2014-09-01

There has been increasing evidence that ascending thoracic aortic aneurysms (TAAs) protect against atherosclerosis. However, there have been no studies examining the relationship between ascending TAAs and clinical endpoints of atherosclerosis, such as stroke or peripheral arterial disease. In this study, we aim to characterize the relationship between TAAs and a specific clinical endpoint of atherosclerosis, myocardial infarction (MI). We compared prevalence of coronary artery disease (CAD) and MIs in 487 patients who underwent surgical repair for ascending TAAs to 500 control patients who did not have an ascending TAA. Multivariate binary logistic regression was used to calculate the odds of having MI if a patient had an ascending TAA versus any of several MI risk factors. There was a significantly lower prevalence of CAD and MI in the ascending TAA group than in the control TAA group. The odds of having a MI if a patient had a MI risk factor were all > 1 (more likely to have a MI), with the lowest statistically significant odds ratio being 1.54 (age; p = 0.001) and the highest being 14.9 (family history of MI; p < 0.001). The odds ratio of having a MI if a patient had an ascending TAA, however, was near 0 at 0.05 (p < 0.001). This study provides evidence that ascending TAAs protect against MIs, adding further support to the hypothesis that ascending TAAs protect against atherosclerotic disease.

Audiovisual communication of object-names improves the spatial accuracy of recalled object-locations in topographic maps.

Knowing the correct location of a specific object learned from a (topographic) map is fundamental for orientation and navigation tasks. Spatial reference systems, such as coordinates or cardinal directions, are helpful tools for any geometric localization of positions that aims to be as exact as possible. Considering modern visualization techniques of multimedia cartography, map elements transferred through the auditory channel can be added easily. Audiovisual approaches have been discussed in the cartographic community for many years. However, the effectiveness of audiovisual map elements for map use has hardly been explored so far. Within an interdisciplinary (cartography-cognitive psychology) research project, it is examined whether map users remember object-locations better if they do not just read the corresponding place names, but also listen to them as voice recordings. This approach is based on the idea that learning object-identities influences learning object-locations, which is crucial for map-reading tasks. The results of an empirical study show that the additional auditory communication of object names not only improves memory for the names (object-identities), but also for the spatial accuracy of their corresponding object-locations. The audiovisual communication of semantic attribute information of a spatial object seems to improve the binding of object-identity and object-location, which enhances the spatial accuracy of object-location memory.

In September 1995, NASA-Goddard held a workshop on low-cost access to space for science missions. The workshop provided briefings on balloons, sounding rockets, Shuttle payloads, and low-cost free-flyer concepts, to provide options of getting experiments into space. This report is the result of a panel session organized with the aim of generating new ideas beyond those presented in the workshop. In addition to the authors, Orlando Figueroa and Paul Ondrus of NASA-Goddard and Richard Zwirnbaum of Computer Sciences Corp. participated in the discussions. The ideas presented do not necessarily reflect the current thinking of NASA managers. Although the panel discussion was focused on the kinds of science missions usually funded by NASA, most of the ideas that were generated are relevant to military and commercial missions as well.

The dementia diagnosis gap in sub-Saharan Africa (SSA) is large, partly due to difficulties in assessing function, an essential step in diagnosis. As part of the Identification and Intervention for Dementia in Elderly Africans (IDEA) study, to develop, pilot, and validate an Instrumental Activities of Daily Living (IADL) questionnaire for use in a rural Tanzanian population to assist in the identification of people with dementia alongside cognitive screening. The questionnaire was developed at a workshop for rural primary healthcare workers, based on culturally appropriate roles and usual activities of elderly people in this community. It was piloted in 52 individuals under follow-up from a dementia prevalence study. Validation subsequently took place during a community dementia-screening programme. Construct validation against gold standard clinical dementia diagnosis using DSM-IV criteria was carried out on a stratified sample of the cohort and validity assessed using area under the receiver operating characteristic (AUROC) curve analysis. An 11-item questionnaire (IDEA-IADL) was developed after pilot testing. During formal validation on 130 community-dwelling elderly people who presented for screening, the AUROC curve was 0.896 for DSM-IV dementia when used in isolation and 0.937 when used in conjunction with the IDEA cognitive screen, previously validated in Tanzania. The internal consistency was 0.959. Performance on the IDEA-IADL was not biased with regard to age, gender or education level. The IDEA-IADL questionnaire appears to be a useful aid to dementia screening in this setting. Further validation in other healthcare settings in SSA is required.

From Young Children's Ideas about Germs to Ideas Shaping a Learning Environment

NASA Astrophysics Data System (ADS)

Ergazaki, Marida; Saltapida, Konstantina; Zogza, Vassiliki

2010-11-01

This paper is concerned with highlighting young children’s ideas about the nature, location and appearance of germs, as well as their reasoning strands about germs’ ontological category and biological functions. Moreover, it is concerned with exploring how all these could be taken into account for shaping a potentially fruitful learning environment. Conducting individual, semi-structured interviews with 35 preschoolers (age 4.5-5.5) of public kindergartens in the broader area of Patras, we attempted to trace their ideas about what germs are, where they may be found, whether they are good or bad and living or non-living and how they might look like in a drawing. Moreover, children were required to attribute a series of biological functions to dogs, chairs and germs, and finally to create a story with germs holding a key-role. The analysis of our qualitative data within the “NVivo” software showed that the informants make a strong association of germs with health and hygiene issues, locate germs mostly in our body and the external environment, are not familiar with the ‘good germs’-idea, and draw germs as ‘human-like’, ‘animal-like’ or ‘abstract’ entities. Moreover, they have significant difficulties not only in employing biological functions as criteria for classifying germs in the category of ‘living’, but also in just attributing such functions to germs using a warrant. Finally, the shift from our findings to a 3-part learning environment aiming at supporting preschoolers in refining their initial conceptualization of germs is thoroughly discussed in the paper.

Computational ghost imaging(CGI), utilizing a single-pixel detector, has been extensively used in many fields. However, in order to achieve a high-quality reconstructed image, a large number of iterations are needed, which limits the flexibility of using CGI in practical situations, especially in the field of object recognition. In this paper, we purpose a method utilizing the feature matching to identify the number objects. In the given system, approximately 90% of accuracy of recognition rates can be achieved, which provides a new idea for the application of single pixel imaging in the field of object recognition

Liver failure is associated with a neuropsychiatric syndrome, known as hepatic encephalopathy (HE). Finasteride, inhibitor of neurosteroid synthesis, may improve the course of HE. The aim of our study was to investigate the influence of finasteride on mean and relative power density of EEG bands, determined by spectral analysis, in rat model of thioacetamide-induced HE. Male Wistar rats were divided into groups: (1) control; (2) thioacetamide-treated group, TAA (900 mg/kg); (3) finasteride-treated group, FIN (150 mg/kg); and (4) group treated with finasteride (150 mg/kg) and thioacetamide (900 mg/kg), FIN + TAA. Daily doses of FIN (50 mg/kg) and TAA (300 mg/kg) were administered during 3 subsequent days, and in FIN + TAA group FIN was administered 2 h before every dose of TAA. EEG was recorded 22-24 h after treatment and analyzed by fast Fourier transformation. While TAA did not induce significant changes in the beta band, mean and relative power in this band were significantly higher in FIN + TAA versus control group (p < 0.01). TAA caused a significant decline in mean power in alpha, theta, and delta band, and in FIN + TAA group the mean power in these bands was significantly higher compared with control. While in TAA group relative power was significantly decreased in theta (p < 0.01) and increased in delta band (p < 0.01) versus control, the opposite changes were found in FIN + TAA group: an increase in theta (p < 0.01) and a decrease in delta relative power (p < 0.01). In this study, finasteride pretreatment caused EEG changes that correspond to mild TAA-induced HE.

A study of Taka-amylase A of conidia from Aspergillus oryzae RIB40 was done. During the research, proteins from conidia and germinated conidia were analyzed using SDS-PAGE, 2-D gel electrophoresis, Western blot analysis, MALDI-TOF Mass spectrometry, and native-PAGE combined with activity staining of TAA. The results showed that TAA exists not only in germinated conidia but also in conidia. Some bands representing degraded products of TAA were detected. Conidia, which formed on starch (SCYA), glucose (DCYA), and glycerol (GCYA) plates, contained mature TAA. Only one active band of TAA was detected after native-PAGE activity staining. In addition, TAA activity was detected in cell extracts of conidia using 0.5 M acetate buffer, pH 5.2, as extraction buffer, but was not detected in whole conidia or cell debris. The results indicate that TAA exists in conidia in active form even when starch, glucose, or glycerol is used as carbon source. TAA might belong to a set of basal proteins inside conidia, which helps in imbibition and germination of conidia.

Preservice Elementary Teachers' Ideas About Scientific Practices

NASA Astrophysics Data System (ADS)

Ricketts, Amy

2014-10-01

With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers' ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants' written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers' content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.

Categorizing Ideas about Trees: A Tree of Trees

PubMed Central

Fisler, Marie; Lecointre, Guillaume

2013-01-01

The aim of this study is to explore whether matrices and MP trees used to produce systematic categories of organisms could be useful to produce categories of ideas in history of science. We study the history of the use of trees in systematics to represent the diversity of life from 1766 to 1991. We apply to those ideas a method inspired from coding homologous parts of organisms. We discretize conceptual parts of ideas, writings and drawings about trees contained in 41 main writings; we detect shared parts among authors and code them into a 91-characters matrix and use a tree representation to show who shares what with whom. In other words, we propose a hierarchical representation of the shared ideas about trees among authors: this produces a “tree of trees.” Then, we categorize schools of tree-representations. Classical schools like “cladists” and “pheneticists” are recovered but others are not: “gradists” are separated into two blocks, one of them being called here “grade theoreticians.” We propose new interesting categories like the “buffonian school,” the “metaphoricians,” and those using “strictly genealogical classifications.” We consider that networks are not useful to represent shared ideas at the present step of the study. A cladogram is made for showing who is sharing what with whom, but also heterobathmy and homoplasy of characters. The present cladogram is not modelling processes of transmission of ideas about trees, and here it is mostly used to test for proximity of ideas of the same age and for categorization. PMID:23950877

The workshop comprised: creating a safe space to explore ideas; discussing the process of posing a question or hypothesis; using group interactions to generate concepts; and considering personal values that influence the choice of research methodology to answer a question. Examples are provided from the workshop. The process enabled trainees to generate and distil ideas into more concrete questions and methods in three phases: introductory, exploratory and tangible. Adult learning principles may assist trainees to develop their ideas for a scholarly project into research questions that are relevant to clinical practice. Harnessing the creative potential of a peer collective may encourage deeper inquiry, shifts to a tangible output and a sustained interest in research.

The trouble with drink: why ideas matter.

PubMed

Edwards, Griffith

2010-05-01

This paper builds upon the work of previous authors who have explored the evolution of ideas in the alcohol arena. With revisions in the relevant sections of ICD and DSM forthcoming, such matters are of considerable contemporary importance. The focus here will be upon the history of the last 200 years. The main themes to be explored include the flux of ideas on what, over time, has counted as the trouble with drink, ideas on the cause of the problem and the impact of this thinking on public action. Medical authorities of the late Enlightenment period made the revolutionary suggestion that habitual drunkenness constituted a disease, rather than a vice. The thread of that idea can be traced to the present day, but with an alternative perception of drink itself or alcohol-related problems generally, as cause for concern, also having a lineage. There are several inferences to be drawn from this history: the need for vigilance lest disease formulations become stalking-horses for moralism and social control, the need to integrate awareness of alcohol dependence as a dimensional individual-level problem, with a public health understanding of the vastly amorphous and at least equally important universe of alcohol-related problems; the dangers lurking in scientific reductionism when the problems at issue truly require a multi-disciplinary analysis; and the need for global consensus rather than cultural imposition of ideas on what counts as the problem with drink.

Graph-Based Object Class Discovery

NASA Astrophysics Data System (ADS)

Xia, Shengping; Hancock, Edwin R.

We are interested in the problem of discovering the set of object classes present in a database of images using a weakly supervised graph-based framework. Rather than making use of the ”Bag-of-Features (BoF)” approach widely used in current work on object recognition, we represent each image by a graph using a group of selected local invariant features. Using local feature matching and iterative Procrustes alignment, we perform graph matching and compute a similarity measure. Borrowing the idea of query expansion , we develop a similarity propagation based graph clustering (SPGC) method. Using this method class specific clusters of the graphs can be obtained. Such a cluster can be generally represented by using a higher level graph model whose vertices are the clustered graphs, and the edge weights are determined by the pairwise similarity measure. Experiments are performed on a dataset, in which the number of images increases from 1 to 50K and the number of objects increases from 1 to over 500. Some objects have been discovered with total recall and a precision 1 in a single cluster.

Developing the nuclear idea: concept, technique, and process.

PubMed

Billow, Richard M

2013-10-01

I introduce an approach to group that has remained undeveloped in the literature, but represents an essence of relationally oriented group psychotherapy. Evolving from the verbalizations and enactments through which the group symbolizes and becomes known-a nuclear idea takes shape. It emerges from the nucleus of the group process: co-created from intersubjective forces and locations that cannot be fully specified, yet may be possible to observe, name, and utilize clinically. Groups organize themselves by developing nuclear ideas, with the therapist's active participation. They are vehicles through which a group comes to think about its thinking: not only what it thinks, but also how it thinks, or chooses not to think, and when and why. Developing the nuclear idea provides a framework for how the therapist-and the group itself-goes about the task of containing. With its emphasis on meaning and the development of meaning as transformational, the concept of the nuclear idea supplements the whole group, interpersonal, and intrapsychic lenses through which the therapist comes to understand group experience and base interventions. Clinical vignettes illustrate how the therapist may develop nuclear ideas thematically, conceptualize further, and negotiate meaning with the co-participation of other group members.

Reduction of Subjective and Objective System Complexity

NASA Technical Reports Server (NTRS)

Watson, Michael D.

2015-01-01

Occam's razor is often used in science to define the minimum criteria to establish a physical or philosophical idea or relationship. Albert Einstein is attributed the saying "everything should be made as simple as possible, but not simpler". These heuristic ideas are based on a belief that there is a minimum state or set of states for a given system or phenomena. In looking at system complexity, these heuristics point us to an idea that complexity can be reduced to a minimum. How then, do we approach a reduction in complexity? Complexity has been described as a subjective concept and an objective measure of a system. Subjective complexity is based on human cognitive comprehension of the functions and inter relationships of a system. Subjective complexity is defined by the ability to fully comprehend the system. Simplifying complexity, in a subjective sense, is thus gaining a deeper understanding of the system. As Apple's Jonathon Ive has stated," It's not just minimalism or the absence of clutter. It involves digging through the depth of complexity. To be truly simple, you have to go really deep". Simplicity is not the absence of complexity but a deeper understanding of complexity. Subjective complexity, based on this human comprehension, cannot then be discerned from the sociological concept of ignorance. The inability to comprehend a system can be either a lack of knowledge, an inability to understand the intricacies of a system, or both. Reduction in this sense is based purely on a cognitive ability to understand the system and no system then may be truly complex. From this view, education and experience seem to be the keys to reduction or eliminating complexity. Objective complexity, is the measure of the systems functions and interrelationships which exist independent of human comprehension. Jonathon Ive's statement does not say that complexity is removed, only that the complexity is understood. From this standpoint, reduction of complexity can be approached

Standard operating procedures in experimental liver research: thioacetamide model in mice and rats.

In addition to carbon tetrachloride (CCl4), thioacetamide (TAA) represents a second widely used model for the induction of experimental liver fibrosis, but can also be employed for the development of acute liver failure and liver tumours. While TAA itself is not hepatotoxic, its reactive metabolites covalently bind to proteins and lipids thereby causing oxidative stress and centrilobular necrosis. Compared with CCl4, TAA leads to more periportal infiltrates and more pronounced ductal proliferation. While TAA has been shown to induce liver fibrosis development in several different mouse strains, wide variations in the administration routes, doses and treatment durations have been reported. Therefore, an adoption of a universal standard operating procedure for the administration of TAA is urgently needed. For that purpose, we are presenting here two TAA models (intraperitoneal administration of 150 mg/kg of TAA three times per week for 11 weeks in rats, and TAA administration in drinking water at 300 mg/L for 2-4 months in mice) with which we have had success in reliably and reproducibly developing chronic liver injury and fibrosis. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Trimeric autotransporter adhesins contribute to Actinobacillus pleuropneumoniae pathogenicity in mice and regulate bacterial gene expression during interactions between bacteria and porcine primary alveolar macrophages.

Actinobacillus pleuropneumoniae is an important pathogen that causes respiratory disease in pigs. Trimeric autotransporter adhesin (TAA) is a recently discovered bacterial virulence factor that mediates bacterial adhesion and colonization. Two TAA coding genes have been found in the genome of A. pleuropneumoniae strain 5b L20, but whether they contribute to bacterial pathogenicity is unclear. In this study, we used homologous recombination to construct a double-gene deletion mutant, ΔTAA, in which both TAA coding genes were deleted and used it in in vivo and in vitro studies to confirm that TAAs participate in bacterial auto-aggregation, biofilm formation, cell adhesion and virulence in mice. A microarray analysis was used to determine whether TAAs can regulate other A. pleuropneumoniae genes during interactions with porcine primary alveolar macrophages. The results showed that deletion of both TAA coding genes up-regulated 36 genes, including ene1514, hofB and tbpB2, and simultaneously down-regulated 36 genes, including lgt, murF and ftsY. These data illustrate that TAAs help to maintain full bacterial virulence both directly, through their bioactivity, and indirectly by regulating the bacterial type II and IV secretion systems and regulating the synthesis or secretion of virulence factors. This study not only enhances our understanding of the role of TAAs but also has significance for those studying A. pleuropneumoniae pathogenesis.

Ideas versus labor: what do children value in artistic creation?

Li, Vivian; Shaw, Alex; Olson, Kristina R

2013-04-01

As scientists, we primarily award authorship, as well as legal patents, to those who generate ideas, often without formally crediting others who executed the actual experiments. However, little is known about how and when people come to value ideas. Here, we investigate whether young children also value ideas over labor. In Study 1, we found that 4 and 6 year olds preferred pictures containing their ideas to those containing their labor. In Study 2 we rule out an alternative explanation-that children simply favor pictures containing their idiosyncratic preferences-by discovering that 6 year olds, but not 4 year olds chose a picture they mistakenly believed contained their idea, over a picture that contained their idiosyncratic preferences. Consistent with these results, using a third-party design in Study 3, we found that 6 year olds, but not 4 year olds favored a person who only contributed an idea over another who only contributed labor in awarding ownership. Across three studies, these results suggest that by 6 years old, children value ideas over labor. Copyright © 2012 Elsevier B.V. All rights reserved.

trans -Aconitic acid (TAA) is an isomer of cis -aconitic acid (CAA), an intermediate of the tricarboxylic acid cycle that is synthesized by aconitase. Although TAA production has been detected in bacteria and plants for many years and is known to be a potent inhibitor of aconitase, its biosynthetic origins and the physiological relevance of its activity have remained unclear. We have serendipitously uncovered key information relevant to both of these questions. Specifically, in a search for novel nematicidal factors from Bacillus thuringiensis , a significant nematode pathogen harboring many protein virulence factors, we discovered a high yielding component that showed activity against the plant-parasitic nematode Meloidogyne incognita and surprisingly identified it as TAA. Comparison with CAA, which displayed a much weaker nematicidal effect, suggested that TAA is specifically synthesized by B. thuringiensis as a virulence factor. Analysis of mutants deficient in plasmids that were anticipated to encode virulence factors allowed us to isolate a TAA biosynthesis-related ( tbr ) operon consisting of two genes, tbrA and tbrB We expressed the corresponding proteins, TbrA and TbrB, and characterized them as an aconitate isomerase and TAA transporter, respectively. Bioinformatics analysis of the TAA biosynthetic gene cluster revealed the association of the TAA genes with transposable elements relevant for horizontal gene transfer as well as a distribution across B. cereus bacteria and other B. thuringiensis strains, suggesting a general role for TAA in the interactions of B. cereus group bacteria with nematode hosts in the soil environment. This study reveals new bioactivity for TAA and the TAA biosynthetic pathway, improving our understanding of virulence factors employed by B. thuringiensis pathogenesis and providing potential implications for nematode management applications. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

Object-based media and stream-based computing

Bove, V. Michael, Jr.

Object-based media refers to the representation of audiovisual information as a collection of objects - the result of scene-analysis algorithms - and a script describing how they are to be rendered for display. Such multimedia presentations can adapt to viewing circumstances as well as to viewer preferences and behavior, and can provide a richer link between content creator and consumer. With faster networks and processors, such ideas become applicable to live interpersonal communications as well, creating a more natural and productive alternative to traditional videoconferencing. In this paper is outlined an example of object-based media algorithms and applications developed by my group, and present new hardware architectures and software methods that we have developed to enable meeting the computational requirements of object- based and other advanced media representations. In particular we describe stream-based processing, which enables automatic run-time parallelization of multidimensional signal processing tasks even given heterogenous computational resources.

The influence of Nietzsche on Freud's ideas.

PubMed

Chapman, A H; Chapman-Santana, M

1995-02-01

The striking analogies between the ideas of Freud and Friedrich Nietzsche, whose works were published from one to three decades before those of Freud, have been commented upon, but no previous systematic correlation of the ideas of Nietzsche and Freud has been made. The major works of Nietzsche were read, and each possible analogy to an idea later broached by Freud was correlated by a systematic review of his works. Any references to Nietzsche in Freud's writings and reported conversation were culled. Concepts of Nietzsche which are similar to those of Freud include (a) the concept of the unconscious mind; (b) the idea that repression pushes unacceptable feelings and thoughts into the unconscious and thus makes the individual emotionally more comfortable and effective; (c) the conception that repressed emotions and instinctual drives later are expressed in disguised ways (for example, hostile feelings and ideas may be expressed as altruistic sentiments and acts); (d) the concept of dreams as complex, symbolic "illusions of illusions" and dreaming itself as a cathartic process which has healthy properties; and (e) the suggestion that the projection of hostile, unconscious feelings onto others, who are then perceived as persecutors of the individual, is the basis of paranoid thinking. Some of Freud's basic terms are identical to those used by Nietzsche. Freud repeatedly stated that he had never read Nietzsche. Evidence contradicting this are his references to Nietzsche and his quotations and paraphrases of him, in causal conversation and his now published personal correspondence, as well as in his early and later writings.

2012-03-01

As scientists seek to understand the nature of our Universe, we can also explore our students' understanding of cosmological concepts. What ideas about the origin, evolution, and fate of our Universe do students bring with them to the classroom? In this talk, I will describe an ongoing study in which students' preinstructional ideas are examined. Topics under investigation include the age of the universe; structure and composition, including dark matter and dark energy; the Big Bang; and how astronomers come to understand these topics. Approximately 1000 students have responded to open-ended questions at the start of their introductory astronomy courses. Analysis of the responses, through an iterative process of identifying self-emergent themes, suggests that students have a number of common ideas. For example, students frequently conflate structure terms such as solar system, galaxy, and universe or do not understand the relationship between the terms; believe the universe to be infinitely old; and may not be aware of dark matter or dark energy. Additional themes, as well as the frequencies of typical responses, will be discussed, and future research efforts.

Unconventional Reservoirs: Ideas to Commercialization

NASA Astrophysics Data System (ADS)

Tinker, S. W.

2015-12-01

There is no shortage of coal, oil, and natural gas in the world. What are sometimes in short supply are fresh ideas. Scientific innovation combined with continued advances in drilling and completion technology revitalized the natural gas industry in North America by making production from shale economic. Similar advances are now happening in shale oil. The convergence of ideas and technology has created a commercial environment in which unconventional reservoirs could supply natural gas to the North American consumer for 50 years or more. And, although not as far along in terms of resource development, oil from the Eagle Ford and Bakken Shales and the oil sands in Alberta could have a similar impact. Without advanced horizontal drilling, geosteering, staged hydraulic-fracture stimulation, synthetic and natural proppants, evolution of hydraulic fluid chemistry, and high-end monitoring and simulation, many of these plays would not exist. Yet drilling and completion technology cannot stand alone. Also required for success are creative thinking, favorable economics, and a tolerance for risk by operators. Current understanding and completion practices will leave upwards of 80% of oil and natural gas in the shale reservoirs. The opportunity to enhance recovery through advanced reservoir understanding and imaging, as well as through recompletions and infill drilling, is considerable. The path from ideas to commercialization will continue to provide economic results in unconventional reservoirs.

The availability of complete genomic sequences for hundreds of organisms promises to make obtaining genome-wide estimates of substitution rates, selective constraints and other molecular evolution variables of interest an increasingly important approach to addressing broad evolutionary questions. Two of the programs most widely used for this purpose are codeml and baseml, parts of the PAML (Phylogenetic Analysis by Maximum Likelihood) suite. A significant drawback of these programs is their lack of a graphical user interface, which can limit their user base and considerably reduce their efficiency. We have developed IDEA (Interactive Display for Evolutionary Analyses), an intuitive graphical input and output interface which interacts with PHYLIP for phylogeny reconstruction and with codeml and baseml for molecular evolution analyses. IDEA's graphical input and visualization interfaces eliminate the need to edit and parse text input and output files, reducing the likelihood of errors and improving processing time. Further, its interactive output display gives the user immediate access to results. Finally, IDEA can process data in parallel on a local machine or computing grid, allowing genome-wide analyses to be completed quickly. IDEA provides a graphical user interface that allows the user to follow a codeml or baseml analysis from parameter input through to the exploration of results. Novel options streamline the analysis process, and post-analysis visualization of phylogenies, evolutionary rates and selective constraint along protein sequences simplifies the interpretation of results. The integration of these functions into a single tool eliminates the need for lengthy data handling and parsing, significantly expediting access to global patterns in the data.

In this case, changing the appearance or behavior of a physical object is intended to cue actions which are appropriate for a given context. The context is defined by the intention of the users, the state of the objects and the tasks for which these objects can be used. We present initial design prototypes and simple user trials which explore the impact of different cues on activity. It is shown that raising the handle of a jug, for example, not only cues the act of picking up the jug but also encourages use of the hand adjacent to the handle; that combinations of lights (on the objects) and auditory cues influence activity through reducing uncertainty; and that cueing can challenge pre-learned action sequences. We interpret these results in terms of the idea that the animate objects can be used to create affording situations, and discuss implications of this work to support relearning of ADL following brain damage or injury, such as might arise following a stroke.

JPL-IDEAS - ITERATIVE DESIGN OF ANTENNA STRUCTURES

NASA Technical Reports Server (NTRS)

Levy, R.

1994-01-01

The Iterative DEsign of Antenna Structures (IDEAS) program is a finite element analysis and design optimization program with special features for the analysis and design of microwave antennas and associated sub-structures. As the principal structure analysis and design tool for the Jet Propulsion Laboratory's Ground Antenna and Facilities Engineering section of NASA's Deep Space Network, IDEAS combines flexibility with easy use. The relatively small bending stiffness of the components of large, steerable reflector antennas allows IDEAS to use pinjointed (three translational degrees of freedom per joint) models for modeling the gross behavior of these antennas when subjected to static and dynamic loading. This facilitates the formulation of the redesign algorithm which has only one design variable per structural element. Input data deck preparation has been simplified by the use of NAMELIST inputs to promote clarity of data input for problem defining parameters, user selection of execution and design options and output requests, and by the use of many attractive and familiar features of the NASTRAN program (in many cases, NASTRAN and IDEAS formatted bulk data cards are interchangeable). Features such as simulation of a full symmetric structure based on analyses of only half the structure make IDEAS a handy and efficient analysis tool, with many features unavailable in any other finite element analysis program. IDEAS can choose design variables such as areas of rods and thicknesses of plates to minimize total structure weight, constrain the structure weight to a specified value while maximizing a natural frequency or minimizing compliance measures, and can use a stress ratio algorithm to size each structural member so that it is at maximum or minimum stress level for at least one of the applied loads. Calculations of total structure weight can be broken down according to material. Center of gravity weight balance, static first and second moments about the center of

IMPORTANCE Follow-up with a primary care provider (PCP) in addition to the surgical team is routinely recommended to patients discharged after major surgery despite no clear evidence that it improves outcomes. OBJECTIVE To test whether PCP follow-up is associated with lower 30-day readmission rates after open thoracic aortic aneurysm (TAA) repair and ventral hernia repair (VHR), surgical procedures known to have a high and low risk of readmission, respectively. DESIGN, SETTING, AND PARTICIPANTS In a cohort of Medicare beneficiaries discharged to home after open TAA repair (n = 12 679) and VHR (n = 52 807) between 2003 to 2010, we compared 30-day readmission rates between patients seen and not seen by a PCP within 30 days of discharge and across tertiles of regional primary care use. We stratified our analysis by the presence of complications during the surgical (index) admission. MAIN OUTCOMES AND MEASURES Thirty-day readmission rate. RESULTS Overall, 2619 patients (20.6%) undergoing open TAA repair and 4927 patients (9.3%) undergoing VHR were readmitted within 30 days after surgery. Complications occurred in 4649 patients (36.6%) undergoing open TAA repair and 4528 patients (8.6%) undergoing VHR during their surgical admission. Early follow-up with a PCP significantly reduced the risk of readmission among open TAA patients who experienced perioperative complications, from 35.0% (without follow-up) to 20.4% (with follow-up) (P < .001). However, PCP follow-up made no significant difference in patients whose hospital course was uncomplicated (19.4% with follow-up vs 21.9% without follow-up; P = .31). In comparison, early follow-up with a PCP after VHR did not reduce the risk of readmission, regardless of complications. In adjusted regional analyses, undergoing open TAA repair in regions with high compared with low primary care use was associated with an 18% lower likelihood of 30-day readmission (odds ratio, 0.82; 95% CI, 0.71–0.96; P = .02), whereas no significant

The idea of philosophical sociology.

PubMed

Chernilo, Daniel

2014-06-01

This article introduces the idea of philosophical sociology as an enquiry into the relationships between implicit notions of human nature and explicit conceptualizations of social life within sociology. Philosophical sociology is also an invitation to reflect on the role of the normative in social life by looking at it sociologically and philosophically at the same: normative self-reflection is a fundamental aspect of sociology's scientific tasks because key sociological questions are, in the last instance, also philosophical ones. For the normative to emerge, we need to move away from the reductionism of hedonistic, essentialist or cynical conceptions of human nature and be able to grasp the conceptions of the good life, justice, democracy or freedom whose normative contents depend on more or less articulated conceptions of our shared humanity. The idea of philosophical sociology is then sustained on three main pillars and I use them to structure this article: (1) a revalorization of the relationships between sociology and philosophy; (2) a universalistic principle of humanity that works as a major regulative idea of sociological research, and; (3) an argument on the social (immanent) and pre-social (transcendental) sources of the normative in social life. As invitations to embrace posthuman cyborgs, non-human actants and material cultures proliferate, philosophical sociology offers the reminder that we still have to understand more fully who are the human beings that populate the social world. © London School of Economics and Political Science 2014.

Aconitum tanguticum has been widely used as a remedy for infectious diseases in traditional Tibetan medicine in China. The total alkaloids of Aconitum tanguticum (TAA) are the main active components of Aconitum tanguticum and have been demonstrated to be effective in suppressing inflammation. Our aim was to investigate the protective effects of TAA on acute lung injury (ALI) induced by lipopolysaccharide (LPS) in rats. TAA was extracted in 95% ethanol and purified in chloroform. After vacuum drying, the TAA powder was dissolved in dimethyl sulfoxide. Adult male Sprague-Dawley rats were randomly divided into six groups. Rats were given dexamethasone (DXM, 4 mg/kg) or TAA (60 mg/kg, 30 mg/kg) before LPS injection. The PaO2and PaO2/FiO2 values, lung wet/dry (W/D) weight ratio and histological changes in lung tissue were measured. The cell counts, protein concentration, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) in bronchoalveolar lavage fluid (BALF), and myeloperoxidase (MPO) activity in lung tissue were determined at 6, 12 or 24 h after LPS treatment. In addition, the NF-κ B activation in lung tissue was analyzed by western blot. In ALI rats, TAA significantly reduced the lung W/D ratio and increased the value of PaO2 or PaO2/FiO2 at 6, 12 or 24 h after LPS challenge. TAA also reduced the total protein concentration and the number of total cells, neutrophils or lymphocytes in BALF. In addition, TAA decreased MPO activity in the lung and attenuated histological changes in the lung. Furthermore, TAA inhibited the concentration of TNF-α, IL-6 and IL-1β in BALF at 6, 12 or 24 h after LPS treatment. Further study demonstrated that TAA significantly inhibited NF-κ B activation in lung tissue. The current study proved that TAA exhibited a potent protective effect on LPS-induced ALI in rats through its anti-inflammatory activity. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Nicotine exerts a number of physiological effects. The purpose of this study was to determine the effects of nicotine on thioacetamide (TAA)-induced liver fibrosis in mice. For in vivo experiments, hepatic fibrosis was induced by TAA (0.25 g/kg, i.p.) three times a week for 6 weeks. Mice of TAA treated groups were administered daily with distilled water and nicotine (50 or 100 μg/mL) via gastrogavage throughout the experimental period. For in vitro experiments, HepG2 (human liver cancer cell line) and LX-2 (human hepatic stellate cell line) were used to determine oxidative stress and fibrosis, respectively. Compared to control groups, TAA treated groups had significantly differences in serum alanine transferase and aspartate aminotransferase levels and nicotine accentuated liver injury. Moreover, nicotine increased the mRNA levels of TAA-induced transforming growth factor-β (TGF-β) and collagen type I alpha 1 in the liver. Nicotine also increased TAA-induced oxidative stress. Histological examination confirmed that nicotine aggravated the degree of fibrosis caused by TAA treatment. Additionally, nicotine enhanced hepatic stellate cell activation via promoting the expression of α-smooth muscle actin. Oral administration of nicotine significantly aggravated TAA-induced hepatic fibrosis in mice through enhancing TGF-β secretion and TAA-induced oxidative stress. The increase in TGF-β levels might be associated with the strengthening of oxidative processes, subsequently leading to increased hepatic stellate cell activation and extracellular matrix deposition. These results suggest that patients with liver disease should be advised to abandon smoking since nicotine may exacerbate hepatic fibrosis.

Enabling Anyone to Translate Clinically Relevant Ideas to Therapies.

Ekins, Sean; Diaz, Natalie; Chung, Julia; Mathews, Paul; McMurtray, Aaron

2017-01-01

How do we inspire new ideas that could lead to potential treatments for rare or neglected diseases, and allow for serendipity that could help to catalyze them? How many potentially good ideas are lost because they are never tested? What if those ideas could have lead to new therapeutic approaches and major healthcare advances? If a clinician or anyone for that matter, has a new idea they want to test to develop a molecule or therapeutic that they could translate to the clinic, how would they do it without a laboratory or funding? These are not idle theoretical questions but addressing them could have potentially huge economic implications for nations. If we fail to capture the diversity of ideas and test them we may also lose out on the next blockbuster treatments. Many of those involved in the process of ideation may be discouraged and simply not know where to go. We try to address these questions and describe how there are options to raising funding, how even small scale investments can foster preclinical or clinical translation, and how there are several approaches to outsourcing the experiments, whether to collaborators or commercial enterprises. While these are not new or far from complete solutions, they are first steps that can be taken by virtually anyone while we work on other solutions to build a more concrete structure for the "idea-hypothesis testing-proof of concept-translation-breakthrough pathway".

Understanding Students’ Ideas about the Geometry of the Universe

Coble, Kimberly A.; Conlon, Mallory; Bailey, Janelle M.

2017-06-01

As astronomers further develop an understanding of the geometry of the Universe, it is essential to study students’ ideas so that instructors can communicate the field’s current status more effectively to their students. In this study, we examine undergraduate students’ pre- instruction ideas in general education astronomy courses (ASTRO 101) at three institutions through pre-course surveys given during the first week of instruction [N ~ 265]. We also examine students’ post-instruction ideas at a single institution through exam questions [N ~ 75] and interviews. Responses are analyzed through an iterative process of identifying self-emergent themes. We examine not only what students think the curvature of the universe is, but also "how we know." We find that many students think the Universe is “round” or that we cannot measure its curvature. Additionally, popular visualizations may enforce incorrect ideas.

Caffeine intake decreases oxidative stress and inflammatory biomarkers in experimental liver diseases induced by thioacetamide: Biochemical and histological study.

Liver disease remains a significant global health problem. Increased caffeine consumption has been associated with a lower prevalence of chronic liver disease. This study aimed to investigate the modifying effects of caffeine on liver injury induced by thioacetamide (TAA) administration in male rats and the possible underlying mechanisms. Forty adult male rats were equally classified into four groups: control group, received only tap water; caffeine-treated group, received caffeine (37.5 mg/kg per day); TAA-treated group, received intraperitoneal (i.p.) TAA (200 mg/kg b.w.) twice a week; and caffeine + TAA-treated group, received combined TAA and caffeine in the same previous doses. After eight weeks of treatment, blood samples were collected for biochemical analysis and liver specimens were prepared for histological and immunohistochemical studies and for assessment of oxidative stress. TAA induced liver toxicity with elevated liver enzymes and histological alterations, fatty changes, apoptosis, and fibrosis evidenced by increased immunohistochemical reaction to matrix metalloproteinase-9 (MMP-9) and collagen type IV in hepatocytes. Also, the levels of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) in serum were significantly elevated. Co-treatment with caffeine and TAA restored normal liver structure and function. Caffeine provided an anti-fibrogenic, anti-inflammatory, and antioxidant effect that was associated with recovery of hepatic histological and functional alterations from TAA-induced hepatotoxicity.

The authors are experienced in working with children and students in the field of early warning and crises management and cartography. All these topics are closely connected to Digital Earth (DE) ideas. On the basis of a questionnaire, the young generation's comprehension of DE concept is clarified. Students from different age groups (from 19 to 36) from different countries and with different social, cultural, economical and political backgrounds are asked to provide definition of DE and describe their basic ideas about meaning, methodology and applications of the concept. The questions aim to discover the young generation's comprehension of DE ideas. They partially cover the newest trends of DE development like social, cultural and environmental issues as well as the styles of new communications (Google Earth, Facebook, LinkedIn, etc.). In order to assure the future development of the DE science, it is important to take into account the young generation's expectations. Some aspects of DE development are considered in the Conclusions.

Who's bringing you hot ideas and how are you responding?

PubMed

Davenport, Thomas H; Prusak, Laurence; Wilson, H James

2003-02-01

There's an unsung hero in your organization. It's the person who's bringing in new ideas from the outside about how to manage better. These aren't your product and service innovators--those people are celebrated loudly and often. This is the manager who, for instance, first uttered the phrase "balance scorecard" in your hallways, or "real options," or "intellectual capital." Managerial innovation is an increasingly important source of competitive advantage--especially given the speed with which product innovations are copied--but it doesn't happen automatically. It takes a certain kind of person to welcome new management ideas and usher them into an organization. The authors recently studied 100 such people to find out how they translate new ideas into action in their organizations. They discovered that they are a distinct type of practitioner; that is to say, they resemble their counterparts in other organizations more than they resemble their own colleagues, and they share a common way of working. "Idea practitioners," as the authors call them, begin by scouting for ideas. All of them are avid readers of management literature and enthusiastic participants in business conferences; many are friendly with business gurus. Once they've identified an idea that seems to hold promise, they tailor it to fit their organizations' specific needs. Next, they actively sell the idea--to senior executives, to the rank and file, to middle managers. And finally, they get the ball rolling by participating in small-scale experiments. But when those take off, they get out of the way and let others execute. In this article, the authors identify the characteristics of idea practitioners and offer strategies for managing them wisely.

Kant on historiography and the use of regulative ideas.

PubMed

Kleingeld, Pauline

2008-12-01

In this paper, I examine Kant's methodological remarks in the 'Idea for a universal history' against the background of the Critique of pure reason. I argue that Kant's approach to the function of regulative ideas of human history as a whole may still be fruitful. This approach allows for regulative ideas that are grand in scope, but modest and fallibilistic in their epistemic status. Kant's methodological analysis should be distinguished from the specific teleological model of history he developed on its basis, however, because this model can no longer be appropriated for current purposes.

Gender approaches to evolutionary multi-objective optimization using pre-selection of criteria

NASA Astrophysics Data System (ADS)

Kowalczuk, Zdzisław; Białaszewski, Tomasz

2018-01-01

A novel idea to perform evolutionary computations (ECs) for solving highly dimensional multi-objective optimization (MOO) problems is proposed. Following the general idea of evolution, it is proposed that information about gender is used to distinguish between various groups of objectives and identify the (aggregate) nature of optimality of individuals (solutions). This identification is drawn out of the fitness of individuals and applied during parental crossover in the processes of evolutionary multi-objective optimization (EMOO). The article introduces the principles of the genetic-gender approach (GGA) and virtual gender approach (VGA), which are not just evolutionary techniques, but constitute a completely new rule (philosophy) for use in solving MOO tasks. The proposed approaches are validated against principal representatives of the EMOO algorithms of the state of the art in solving benchmark problems in the light of recognized EC performance criteria. The research shows the superiority of the gender approach in terms of effectiveness, reliability, transparency, intelligibility and MOO problem simplification, resulting in the great usefulness and practicability of GGA and VGA. Moreover, an important feature of GGA and VGA is that they alleviate the 'curse' of dimensionality typical of many engineering designs.

What's the Big Idea? Seeking to Top Apollo

2012-01-01

Human space flight has struggled to find its soul since Apollo. The astounding achievements of human space programs over the 40 years since Apollo have failed to be as iconic or central to society as in the 1960s. The paper proffers a way human space flight could again be associated with a societal Big Idea. It describes eight societal factors that have irrevocably changed since Apollo; then analyzes eight other factors that a forward HSF Big Idea would have to fit. The paper closes by assessing the four principal options for HSF futures against those eight factors. Robotic and human industrialization of geosynchronous orbit to provide unlimited, sustainable electrical power to Earth is found to be the best candidate for the next Big Idea.

Grammar-based processor generation is one of the most widely studied areas in language processor construction. However, there have been very few approaches to date that reconcile object-oriented principles, processor generation, and an object-oriented language. Pertinent here also. is that currently to develop a processor using the Eiffel Parse libraries requires far too much time to be expended on tasks that can be automated. For these reasons, we have developed YOOCC (Yes! an Object-Oriented Compiler Compiler), which produces a processor framework from a grammar using an enhanced version of the Eiffel Parse libraries, incorporating the ideas hypothesized by Meyer, and Grapemore » and Walden, as well as many others. Various essential changes have been made to the Eiffel Parse libraries. Examples are presented to illustrate the development of a processor using YOOCC, and it is concluded that the Eiffel Parse libraries are now not only an intelligent, but also a productive option for processor construction.« less

The observational astronomy workshop focused on teaching educators a few basics about naked-eye, binocular, and small telescope observing; while the computers in astronomy education workshop taught teachers to develop simple web sites and permitted them to test astronomy software. The observational astronomy workshop met for three days on the SCSU campus to teach basic celestial motions, several constellations, and the basic operation of small telescopes. The next four nights were spent at Camden State Park in southwest Minnesota learning to locate deep sky objects and preparing public presentations. The final two nights the teachers presented public observing programs at three state parks. Fifty percent of the teachers implemented night observing into their curriculum this past year, and one teacher purchased her own telescope to use with students and to help other teachers in the district. The computers in astronomy workshop introduced the teachers to several commercially available astronomy software packages and taught them the fundamentals of constructing simple web pages. The participants were required to develop astronomy lessons based on one of the software packages or a web site that they developed. Each participant then constructed a web-based lesson plan, student lesson, and teacher's guide for their lesson. These lessons are available at http://enstein.stcloudstate.edu/nook/IDEAS/computers/. Support for this work was provided by NASA through grant numbers ED-90156.01-97A and ED-90157.01-97A from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Incorporated, under NASA contract NAS5-26555.

Determinism, independence, and objectivity are incompatible.

PubMed

Ionicioiu, Radu; Mann, Robert B; Terno, Daniel R

Hidden-variable models aim to reproduce the results of quantum theory and to satisfy our classical intuition. Their refutation is usually based on deriving predictions that are different from those of quantum mechanics. Here instead we study the mutual compatibility of apparently reasonable classical assumptions. We analyze a version of the delayed-choice experiment which ostensibly combines determinism, independence of hidden variables on the conducted experiments, and wave-particle objectivity (the assertion that quantum systems are, at any moment, either particles or waves, but not both). These three ideas are incompatible with any theory, not only with quantum mechanics.

Bio-chemo-mechanics of thoracic aortic aneurysms.

PubMed

Wagenseil, Jessica E

2018-03-01

Most thoracic aortic aneurysms (TAAs) occur in the ascending aorta. This review focuses on the unique bio-chemo-mechanical environment that makes the ascending aorta susceptible to TAA. The environment includes solid mechanics, fluid mechanics, cell phenotype, and extracellular matrix composition. Advances in solid mechanics include quantification of biaxial deformation and complex failure behavior of the TAA wall. Advances in fluid mechanics include imaging and modeling of hemodynamics that may lead to TAA formation. For cell phenotype, studies demonstrate changes in cell contractility that may serve to sense mechanical changes and transduce chemical signals. Studies on matrix defects highlight the multi-factorial nature of the disease. We conclude that future work should integrate the effects of bio-chemo-mechanical factors for improved TAA treatment.

Clinical prediction and the idea of a population.

PubMed

Armstrong, David

2017-04-01

Using an analysis of the British Medical Journal over the past 170 years, this article describes how changes in the idea of a population have informed new technologies of medical prediction. These approaches have largely replaced older ideas of clinical prognosis based on understanding the natural histories of the underlying pathologies. The 19 th -century idea of a population, which provided a denominator for medical events such as births and deaths, was constrained in its predictive power by its method of enumerating individual bodies. During the 20 th century, populations were increasingly constructed through inferential techniques based on patient groups and samples seen to possess variable characteristics. The emergence of these new virtual populations created the conditions for the emergence of predictive algorithms that are used to foretell our medical futures.

Students' Ideas and Radical Constructivism

NASA Astrophysics Data System (ADS)

Sánchez Gómez, Pedro J.

2016-08-01

In this article, I study, from the point of view of the analytic philosophy of mind, the compatibility of students' ideas studies (SIS) with radical constructivism (RC). I demonstrate that RC is based on a psychology of narrow mental states; that is, the idea that the mental content of an individual can be fully characterised without any reference external to her or him. I show that this fact imposes some severe restrictions to SIS to be incorporated into RC. In particular, I argue that only qualitative studies can comply with the requirement of narrowness. Nevertheless, I propose that quantitative works can be employed as sources of types in order to study token actual students. I use this type-token dichotomy to put forward an outline of a theory of the relation between school contents and mental contents. In this view, token mental contents regarding a given topic can be defined, and probed, only by resorting to typical school contents.

An approach to computing direction relations between separated object groups

2013-06-01

Direction relations between object groups play an important role in qualitative spatial reasoning, spatial computation and spatial recognition. However, none of existing models can be used to compute direction relations between object groups. To fill this gap, an approach to computing direction relations between separated object groups is proposed in this paper, which is theoretically based on Gestalt principles and the idea of multi-directions. The approach firstly triangulates the two object groups; and then it constructs the Voronoi Diagram between the two groups using the triangular network; after this, the normal of each Vornoi edge is calculated, and the quantitative expression of the direction relations is constructed; finally, the quantitative direction relations are transformed into qualitative ones. The psychological experiments show that the proposed approach can obtain direction relations both between two single objects and between two object groups, and the results are correct from the point of view of spatial cognition.

2017-10-01

The attitude information acquisition of unresolved space objects, such as micro-nano satellites and GEO objects under the way of ground-based optical observations, is a challenge to space surveillance. In this paper, a useful method is proposed to estimate the SO attitude state according to the simulation analysis of photometric data in different attitude states. The object shape model was established and the parameters of the BRDF model were determined, then the space object photometric model was established. Furthermore, the photometric data of space objects in different states are analyzed by simulation and the regular characteristics of the photometric curves are summarized. The simulation results show that the photometric characteristics are useful for attitude inversion in a unique way. Thus, a new idea is provided for space object identification in this paper.

Background Pathogenic bacteria adhere to the host cell surface using a family of outer membrane proteins called Trimeric Autotransporter Adhesins (TAAs). Although TAAs are highly divergent in sequence and domain structure, they are all conceptually comprised of a C-terminal membrane anchoring domain and an N-terminal passenger domain. Passenger domains consist of a secretion sequence, a head region that facilitates binding to the host cell surface, and a stalk region. Methodology/Principal Findings Pathogenic species of Burkholderia contain an overabundance of TAAs, some of which have been shown to elicit an immune response in the host. To understand the structural basis for host cell adhesion, we solved a 1.35 Å resolution crystal structure of a BpaA TAA head domain from Burkholderia pseudomallei, the pathogen that causes melioidosis. The structure reveals a novel fold of an intricately intertwined trimer. The BpaA head is composed of structural elements that have been observed in other TAA head structures as well as several elements of previously unknown structure predicted from low sequence homology between TAAs. These elements are typically up to 40 amino acids long and are not domains, but rather modular structural elements that may be duplicated or omitted through evolution, creating molecular diversity among TAAs. Conclusions/Significance The modular nature of BpaA, as demonstrated by its head domain crystal structure, and of TAAs in general provides insights into evolution of pathogen-host adhesion and may provide an avenue for diagnostics.

Trans-Membrane Area Asymmetry Controls the Shape of Cellular Organelles

Membrane organelles often have complicated shapes and differ in their volume, surface area and membrane curvature. The ratio between the surface area of the cytosolic and luminal leaflets (trans-membrane area asymmetry (TAA)) determines the membrane curvature within different sites of the organelle. Thus, the shape of the organelle could be critically dependent on TAA. Here, using mathematical modeling and stereological measurements of TAA during fast transformation of organelle shapes, we present evidence that suggests that when organelle volume and surface area are constant, TAA can regulate transformation of the shape of the Golgi apparatus, endosomal multivesicular bodies, and microvilli of brush borders of kidney epithelial cells. Extraction of membrane curvature by small spheres, such as COPI-dependent vesicles within the Golgi (extraction of positive curvature), or by intraluminal vesicles within endosomes (extraction of negative curvature) controls the shape of these organelles. For instance, Golgi tubulation is critically dependent on the fusion of COPI vesicles with Golgi cisternae, and vice versa, for the extraction of membrane curvature into 50–60 nm vesicles, to induce transformation of Golgi tubules into cisternae. Also, formation of intraluminal ultra-small vesicles after fusion of endosomes allows equilibration of their TAA, volume and surface area. Finally, when microvilli of the brush border are broken into vesicles and microvilli fragments, TAA of these membranes remains the same as TAA of the microvilli. Thus, TAA has a significant role in transformation of organelle shape when other factors remain constant. PMID:25761238

Two semiconducting naphthalene bisimides were comparatively studied: NBI-(TAA)(2), symmetrically N-substituted with triaryl amine and asymmetric NBI-TAA-Oc with triaryl amine and octyl N-substituents. Both compounds show very similar spectroscopic and redox properties but differ in their supramolecular organization. As evidenced by STM, in monolayers on HOPG they form ordered 2D structures, however of different packing patterns. NBI-(TAA)(2) does not form ordered 3D structures, yielding amorphous thin films whereas films of NBI-TAA-Oc are highly crystalline. DFT calculations predict the ionization potential (IP) of 5.22 eV and 5.18 eV for NBI-TAA-Oc and NBI-(TAA)(2), respectively, as well as the electron affinity values (EA) of -3.25 eV and -3.22 eV. These results are consistent with the cyclic voltammetry data which yield similar values of IP (5.20 eV and 5.19 eV) and somehow different values of EA (-3.80 eV and -3.83 eV). As judged from these data, both semiconductors should exhibit ambipolar behavior. Indeed, NBI-TAA-Oc is ambipolar, showing hole and electron mobilities of 4.5 × 10(-5) cm(2)/(V s) and of 2.6 × 10(-4) cm(2)/(V s), respectively, in the field effect transistor configuration. NBI-(TAA)(2) is not ambipolar and yields field effect only in the p-channel configuration. This different behavior is rationalized on the basis of structural factors.

The idea of the library in the twenty-first century*

Matheson, Nina W.

2012-01-01

The fundamental idea of the library must change. The nineteenth-century idea of the library as the embalming of dead genius and the twentieth-century idea of the library as the repository for secondhand knowledge must give way to the idea of the library as the owner and the librarian as the manager of first-hand knowledge. In the coming era of knowledge capitalism, those individuals and organizations will flourish who are able to apply knowledge to create knowledge and to organize it to produce knowledge. The roles of present-day librarians and libraries will begin to differentiate sharply over the next decade. Some must seize the opportunity to participate in the transformation of libraries into online knowledge servers. PMID:23509431

[The prevalence of suicide ideas and their psychosocial backgrounds among physicians].

A growing body of evidence in the literature suggests that the prevalence of psychiatric morbidity including suicide is high among physicians. Suicidal ideas are the most important predictors of suicides and suicide attempts. The prevalence of suicidal ideas is higher among physicians compared to the general population. Our goal was to search the factors of suicidal ideas among Hungarian physicians on basis of nationwide representative survey, helping to elaborate prevention programs. Data were collected from 298 female and 109 male physicians using questionnaires. 1,754 white-collar workers from a representative survey (Hungarostudy 2002) served as controls. Statistical analysis examined background factors of suicidal thoughts. We found that the prevalence of suicidal ideas among both female (20,3%) and male physicians (12,1%) was significantly higher than that in the respective control groups (12,3% - 7,6%). Female physicians also exhibited significantly higher prevalence of suicidal ideas (p=0.0058 és OR=1,901). Suicidal ideas were associated with work-related stress. Correlation analyses confirmed a significant relationship between high prevalence of suicidal ideas and long working hours (>8 hours), severe anxiety and work-related stress, and role conflict. Further examination of the background factors of suicidal thoughts may help to elaborate more effective health-prevention and conflict-dealing methods.

Infrequent social interaction can accelerate the spread of a persuasive idea.

PubMed

Burridge, James; Gnacik, Michał

2016-12-01

We study the spread of a persuasive new idea through a population of continuous-time random walkers in one dimension. The idea spreads via social gatherings involving groups of nearby walkers who act according to a biased "majority rule": After each gathering, the group takes on the new idea if more than a critical fraction 1-ɛ/2<1/2 of them already hold it; otherwise they all reject it. The boundary of a domain where the new idea has taken hold expands as a traveling wave in the density of new idea holders. Our walkers move by Lévy motion, and we compute the wave velocity analytically as a function of the frequency of social gatherings and the exponent of the jump distribution. When this distribution is sufficiently heavy tailed, then, counter to intuition, the idea can propagate faster if social gatherings are held less frequently. When jumps are truncated, a critical gathering frequency can emerge which maximizes propagation velocity. We explore our model by simulation, confirming our analytical results.

The role of CYP2A5 in liver injury and fibrosis: chemical-specific difference

2015-01-01

Liver injuries induced by carbon tetrachloride (CCL4) or thioacetamide (TAA) are dependent on cytochrome P450 2E1 (CYP2E1). CYP2A5 can be induced by TAA but not by CCL4. In this study, liver injury including fibrosis induced by CCL4 or TAA were investigated in wild type (WT) mice and CYP2A5 knockout (cyp2a5−/−) mice as well as in CYP2E1 knockout (cyp2e1−/−) mice as a comparison. Acute and sub-chronic liver injuries including fibrosis were induced by CCL4 and TAA in WT mice but not in cyp2e1−/− mice, confirming the indispensable role of CYP2E1 in CCL4 and TAA hepatotoxicity. WT mice and cyp2a5−/− mice developed comparable acute liver injury induced by a single injection of CCL4 as well as sub-chronic liver injury including fibrosis induced by one month of repeated administration of CCL4, suggesting that CYP2A5 does not affect CCL4-induced liver injury and fibrosis. However, while 200 mg/kg TAA-induced acute liver injury was comparable in WT mice and cyp2a5−/− mice, 75 and 100 mg/kg TAA-induced liver injury were more severe in cyp2a5−/− mice than those found in WT mice. After multiple injections with 200 mg/kg TAA for one month, while sub-chronic liver injury as indicated by serum aminotransferases was comparable in WT mice and cyp2a5−/− mice, liver fibrosis was more severe in cyp2a5−/− mice than that found in WT mice. These results suggest that while both CCL4- and TAA-induced liver injuries and fibrosis are CYP2E1 dependent, under some conditions, CYP2A5 may protect against TAA-induced liver injury and fibrosis, but it doesn’t affect CCL4 hepatotoxicity.

Detailed 3D representations for object recognition and modeling.

PubMed

Zia, M Zeeshan; Stark, Michael; Schiele, Bernt; Schindler, Konrad

2013-11-01

Geometric 3D reasoning at the level of objects has received renewed attention recently in the context of visual scene understanding. The level of geometric detail, however, is typically limited to qualitative representations or coarse boxes. This is linked to the fact that today's object class detectors are tuned toward robust 2D matching rather than accurate 3D geometry, encouraged by bounding-box-based benchmarks such as Pascal VOC. In this paper, we revisit ideas from the early days of computer vision, namely, detailed, 3D geometric object class representations for recognition. These representations can recover geometrically far more accurate object hypotheses than just bounding boxes, including continuous estimates of object pose and 3D wireframes with relative 3D positions of object parts. In combination with robust techniques for shape description and inference, we outperform state-of-the-art results in monocular 3D pose estimation. In a series of experiments, we analyze our approach in detail and demonstrate novel applications enabled by such an object class representation, such as fine-grained categorization of cars and bicycles, according to their 3D geometry, and ultrawide baseline matching.

Revisiting child-based objections to commercial surrogacy.

PubMed

Hanna, Jason K M

2010-09-01

Many critics of commercial surrogate motherhood argue that it violates the rights of children. In this paper, I respond to several versions of this objection. The most common version claims that surrogacy involves child-selling. I argue that while proponents of surrogacy have generally failed to provide an adequate response to this objection, it can be overcome. After showing that the two most prominent arguments for the child-selling objection fail, I explain how the commissioning couple can acquire parental rights by paying the surrogate only for her reproductive labor. My explanation appeals to the idea that parental rights are acquired by those who have claims over the reproductive labor that produces the child, not necessarily by those who actually perform the labor. This account clarifies how commercial surrogacy differs from commercial adoption. In the final section of the paper, I consider and reject three further child-based objections to commercial surrogacy: that it establishes a market in children's attributes, that it requires courts to stray from the best interests standard in determining custodial rights, and that it requires the surrogate to neglect her parental responsibilities. Since each of these objections fails, children's rights probably do not pose an obstacle to the acceptability of commercial surrogacy arrangements.

We have previously reported that α-amylase (Taka-amylase A, TAA) activity disappears in the later stage of submerged Aspergillus oryzae culture as a result of TAA adsorption onto the cell wall. Chitin, one of the major components of the cell wall, was identified as a potential factor that facilitates TAA adsorption. However, TAA adsorption only occurred in the later stage of cultivation, although chitin was assumed to be sufficiently abundant in the cell wall regardless of the submerged culture period. This suggested the presence a factor that inhibits TAA adsorption to the cell wall in the early stage of cultivation. In the current study, we identified α-1,3-glucan as a potential inhibiting factor for TAA adsorption. We constructed single, double, and triple disruption mutants of three α-1,3-glucan synthase genes (agsA, agsB, and agsC) in A. oryzae. Growth characteristics and cell wall component analysis of these disruption strains showed that AgsB plays a major role in α-1,3-glucan synthesis. In the ΔagsB mutant, TAA was adsorbed onto the mycelium in all stages of cultivation (early and later), and the ΔagsB mutant cell walls had a significantly high capacity for TAA adsorption. Moreover, the α-1,3-glucan content of the cell wall prepared from the wild-type strain in the later stage of cultivation was markedly reduced compared with that in the early stage. These results suggest that α-1,3-glucan is a potential inhibiting factor for TAA adsorption onto the cell wall component, chitin, in the early stage of submerged culture in A. oryzae.

Towards Robust Designs Via Multiple-Objective Optimization Methods

NASA Technical Reports Server (NTRS)

Man Mohan, Rai

2006-01-01

Fabricating and operating complex systems involves dealing with uncertainty in the relevant variables. In the case of aircraft, flow conditions are subject to change during operation. Efficiency and engine noise may be different from the expected values because of manufacturing tolerances and normal wear and tear. Engine components may have a shorter life than expected because of manufacturing tolerances. In spite of the important effect of operating- and manufacturing-uncertainty on the performance and expected life of the component or system, traditional aerodynamic shape optimization has focused on obtaining the best design given a set of deterministic flow conditions. Clearly it is important to both maintain near-optimal performance levels at off-design operating conditions, and, ensure that performance does not degrade appreciably when the component shape differs from the optimal shape due to manufacturing tolerances and normal wear and tear. These requirements naturally lead to the idea of robust optimal design wherein the concept of robustness to various perturbations is built into the design optimization procedure. The basic ideas involved in robust optimal design will be included in this lecture. The imposition of the additional requirement of robustness results in a multiple-objective optimization problem requiring appropriate solution procedures. Typically the costs associated with multiple-objective optimization are substantial. Therefore efficient multiple-objective optimization procedures are crucial to the rapid deployment of the principles of robust design in industry. Hence the companion set of lecture notes (Single- and Multiple-Objective Optimization with Differential Evolution and Neural Networks ) deals with methodology for solving multiple-objective Optimization problems efficiently, reliably and with little user intervention. Applications of the methodologies presented in the companion lecture to robust design will be included here. The

Mental object rotation and the planning of hand movements.

PubMed

Wohlschläger, A

2001-05-01

Recently, we showed that the simultaneous execution of rotational hand movements interferes with mental object rotation, provided that the axes of rotation coincide in space. We hypothesized that mental object rotation and the programming of rotational hand movements share a common process presumably involved in action planning. Two experiments are reported here that show that the mere planning of a rotational hand movement is sufficient to cause interference with mental object rotation. Subjects had to plan different spatially directed hand movements that they were asked to execute only after they had solved a mental object rotation task. Experiment 1 showed that mental object rotation was slower if hand movements were planned in a direction opposite to the presumed mental rotation direction, but only if the axes of hand rotation and mental object rotation were parallel in space. Experiment 2 showed that this interference occurred independent of the preparatory hand movements observed in Experiment 1. Thus, it is the planning of hand movements and not their preparation or execution that interferes with mental object rotation. This finding underlines the idea that mental object rotation is an imagined (covert) action, rather than a pure visual-spatial imagery task, and that the interference between mental object rotation and rotational hand movements is an interference between goals of actions.

Xenogeneic therapeutic cancer vaccines as breakers of immune tolerance for clinical application: to use or not to use?

Accumulation of firm evidence that clinically apparent cancer develops only when malignant cells manage to escape immunosurveillance led to the introduction of tumor immunotherapy strategies aiming to reprogramm the cancer-dysbalanced antitumor immunity and restore its capacity to control tumor growth. There are several immunotherapeutical strategies, among which specific active immunotherapy or therapeutic cancer vaccination is one of the most promising. It targets dendritic cells (DCs) which have a unique ability of inducing naive and central memory T cell-mediated immune response in the most efficient manner. DCs can be therapeutically targeted either in vivo/in situ or by ex vivo manipulations followed by their re-injection back into the same patient. The majority of current DC targeting strategies are based on autologous or allogeneic tumor-associated antigens (TAAs) which possess various degrees of inherent tolerogenic potential. Therefore still limited efficacy of various tumor immunotherapy approaches may be attributed, among various other mechanisms, to the insufficient immunogenicity of self-protein-derived TAAs. Based on such an idea, the use of homologous xenogeneic antigens, derived from different species was suggested to overcome the natural immune tolerance to self TAAs. Xenoantigens are supposed to differ sufficiently from self antigens to a degree that renders them immunogenic, but at the same time preserves an optimal homology range with self proteins still allowing xenoantigens to induce cross-reactive T cells. Here we discuss the concept of xenogeneic vaccination, describe the cons and pros of autologous/allogeneic versus xenogeneic therapeutic cancer vaccines, present the results of various pre-clinical and several clinical studies and highlight the future perspectives of integrating xenovaccination into rapidly developing tumor immunotherapy regimens.

Cosmic Evolution: The History of an Idea

NASA Astrophysics Data System (ADS)

Dick, S. J.

2004-12-01

Cosmic evolution has become the conceptual framework within which modern astronomy is undertaken, and is the guiding principle of major NASA programs such as Origins and Astrobiology. While there are 19th- and early 20th century antecedents, as in the work of Robert Chambers, Herbert Spencer and Lawrence Henderson, it was only at mid-20th century that full-blown cosmic evolution began to be articulated and accepted as a research paradigm extending from the Big Bang to life, intelligence and the evolution of culture. Harlow Shapley was particularly important in spreading the idea to the public in the 1950s, and NASA embraced the idea in the 1970s as part of its SETI program and later its exobiology and astrobiology programs. Eric Chaisson, Carl Sagan and others were early proponents of cosmic evolution, and it continues to be elaborated in ever more subtle form as a research program and a philosophy. It has even been termed "Genesis for the 21st century." This paper documents the origin and development of the idea and offers a glimpse of where it could lead if cultural evolution is taken seriously, possibly leading to the concept of a postbiological universe.

Nursings' need for the idea of spirituality.

PubMed

Pesut, Barbara

2013-03-01

Spirituality is an idea that has sustained significant interest in nursing over the past quarter century. Extensive conceptual work has generated robust critique around clarity and professional jurisdictional claims. However, less attention has been paid to the challenges nursing has faced that have contributed to the spirituality quest. Reflecting on my own experiences as a scholar writing in this literature over the past decade, I suggest three challenges that spirituality has attempted to redress: to relate across difference in a globalized world, to be good in a world of uncertain morality and to find meaning in a disenchanted world. The idea of spirituality could be viewed as resistance against othering, against law based ethics, and against politics and power. But the impact of the idea of spirituality has yet to be determined and caution is in order. As important as this resistance is, nursing must refrain from creating a new world of insiders and outsiders and from minimizing the role of religious ethics in a globalized world. Spirituality, like its predecessor religion, will likely continue to play an enduring role in providing fundamental meaning for nursing work. © 2012 Blackwell Publishing Ltd.

Knowing a winning business idea when you see one.

PubMed

Kim, W C; Mauborgne, R

2000-01-01

Identifying which business ideas have real commercial potential is fraught with uncertainty, and even the most admired companies have stumbled. It's not as if they don't know what the challenges of innovation are. A new product has to offer customers exceptional utility at an attractive price, and the company must be able to deliver it at a tidy profit. But the uncertainties surrounding innovation are so great that even the most insightful managers have a hard time evaluating the commercial readiness of new business ideas. In this article, W. Chan Kim and Renée Mauborgne introduce three tools that managers can use to help strip away some of that uncertainty. The first tool, "the buyer utility map," indicates how likely it is that customers will be attracted to a new business idea. The second, "the price corridor of the mass," identifies what price will unlock the greatest number of customers. And the third tool, "the business model guide," offers a framework for figuring out whether and how a company can profitably deliver the new idea at the targeted price. Applying the tools, though, is not the end of the story. Many innovations have to overcome adoption hurdles--strong resistance from stakeholders inside and outside the company. Often overlooked in the planning process, adoption hurdles can make or break the commercial viability of even the most powerful new ideas. The authors conclude by discussing how managers can head off negative reactions from stakeholders.

The passing of a law is frequently accompanied by media attention and citizen apathy. In today's healthcare delivery situation, we should understand how a bill becomes law and what happens to the idea that engenders that process. Laws arise from the recommendations of ordinary citizens, but the recommendations follow a complicated process developed by the writers of our constitution to prevent abuses. Laws begin as ideas, they become bills considered by the legislature, they are expanded and enforced by the executive branch, and they are further interpreted by the judiciary branch. The laws governing healthcare issues are particularly complex, as most arise from the state legislatures.

Clinical trials are expensive and lengthy, where success of a given trial depends on observing a prospectively defined number of patient events required to answer the clinical question. The point at which this analysis time occurs depends on both patient accrual and primary event rates, which typically vary throughout the trial's duration. We demonstrate real-time analysis date projections using data from a collection of six clinical trials that are part of the IDEA collaboration, an international preplanned pooling of data from six trials testing the duration of adjuvant chemotherapy in stage III colon cancer, and we additionally consider the hypothetical impact of one trial's early termination of follow-up. In the absence of outcome data from IDEA, monthly accrual rates for each of the six IDEA trials were used to project subsequent trial-specific accrual, while historical data from similar Adjuvant Colon Cancer Endpoints (ACCENT) Group trials were used to construct a parametric model for IDEA's primary endpoint, disease-free survival, under the same treatment regimen. With this information and using the planned total accrual from each IDEA trial protocol, individual patient accrual and event dates were simulated and the overall IDEA interim and final analysis times projected. Projections were then compared with actual (previously undisclosed) trial-specific event totals at a recent census time for validation. The change in projected final analysis date assuming early termination of follow-up for one IDEA trial was also calculated. Trial-specific predicted event totals were close to the actual number of events per trial for the recent census date at which the number of events per trial was known, with the overall IDEA projected number of events only off by eight patients. Potential early termination of follow-up by one IDEA trial was estimated to postpone the overall IDEA final analysis date by 9 months. Real-time projection of the final analysis time during a

One type of anticancer vaccine relies on the administration of DNA constructs encoding one or multiple tumor-associated antigens (TAAs). The ultimate objective of these preparations, which can be naked or vectored by non-pathogenic viruses, bacteria or yeast cells, is to drive the synthesis of TAAs in the context of an immunostimulatory milieu, resulting in the (re-)elicitation of a tumor-targeting immune response. In spite of encouraging preclinical results, the clinical efficacy of DNA-based vaccines employed as standalone immunotherapeutic interventions in cancer patients appears to be limited. Thus, efforts are currently being devoted to the development of combinatorial regimens that allow DNA-based anticancer vaccines to elicit clinically relevant immune responses. Here, we discuss recent advances in the preclinical and clinical development of this therapeutic paradigm.

The fixation effect is known as one of the most dominant of the cognitive biases against creativity and limits individuals’ creative capacities in contexts of idea generation. Numerous techniques and tools have been established to help overcome these cognitive biases in various disciplines ranging from neuroscience to design sciences. Several works in the developmental cognitive sciences have discussed the importance of inhibitory control and have argued that individuals must first inhibit the spontaneous ideas that come to their mind so that they can generate creative solutions to problems. In line with the above discussions, in the present study, we performed an experiment on one hundred undergraduates from the Faculty of Psychology at Paris Descartes University, in which we investigated a minimal executive feedback-based learning process that helps individuals inhibit intuitive paths to solutions and then gradually drive their ideation paths toward creativity. Our results provide new insights into novel forms of creative leadership for idea generation. PMID:28662154

Thoracic aortic aneurysm (TAA) is an often asymptomatic disease with fatal outcome, such as dissection or rupture. The megaaortic syndrome (MAS) is an extensive dilatation of the whole aorta with low incidence but high lethal outcome with unknown pathophysiology so far. We compared aortic tissue of patients with sporadic TAAs and MAS of the ascending aorta with non-aneurysmal control tissues. Specimens of MAS patients showed a significantly reduced thickness of the media but an increased thickness of the intima compared to control tissue and TAAs with moderate dilatation. Advanced media degeneration however was detectable in both, TAAs with enhanced luminal diameter and MAS specimens, accompanied by reduced medial smooth muscle cell-density. Further specimens of MAS were characterized by massive atherosclerotic lesions in contrast to specimens of sporadic TAA patients. Infiltrations of macrophages in atherosclerotic lesions but also in the media adjacent to the adventitia were significantly elevated in tissue of TAAs with dilatation ≤6cm. Of note, atherosclerotic plaque-associated macrophages as well as those in the external media produce huge amounts of MMP-9 which is possibly involved in media degeneration and tissue destruction. Taken together these results demonstrate that the pathology of MAS shows similarities with that of TAAs but pathological differences in the ascending aorta, suggesting that MAS might be a disease of different origin.

This disappearance was caused by adsorption of TAA onto the cell wall of A. oryzae and not due to protein degradation by extracellular proteolytic enzymes. To determine the cell wall component(s) that allows TAA adsorption efficiently, the cell wall was fractionated by stepwise alkali treatment and enzymatic digestion. Consequently, alkali-insoluble cell wall fractions exhibited high levels of TAA adsorption. In addition, this adsorption capacity was significantly enhanced by treatment of the alkali-insoluble fraction with β-glucanase, which resulted in the concomitant increase in the amount of chitin in the resulting fraction. In contrast, the adsorption capacity was diminished by treating the cell wall fraction with chitinase. These results suggest that the major component that allows TAA adsorption is chitin. However, both the mycelium and the cell wall demonstrated the inability to allow TAA adsorption in the early stage of cultivation, despite chitin content in the cell wall being identical in both early and late stages of cultivation. These results suggest the existence of unidentified factor(s) that could prevent the adsorption of TAA onto the cell wall. Such factor(s) is most likely removed or diminished from the cell wall following longer cultivation periods.

This study aimed to evaluate the protective effects of curcumin on angiotensin-converting enzyme (ACE) gene expression, oxidative stress and anti-oxidant status in thioacetamide (TAA)-induced hepatotoxicity in rats. Total 32 albino Wistar rats (male, 200-250 g) were divided into six groups (n=8). Group 1: untreated controls; Group 2: received TAA (200 mg/kg body weight (b.w.); i.p.) for 12 weeks; Group 3: received curcumin (75 mg/kg b.w.) for 24 weeks; Group 4: received TAA (200 mg/kg b.w.; i.p.) for 12 weeks+curcumin (75 mg/kg b.w.) for 12 weeks. A significantly higher ACE gene expression was observed in TAA-induced groups as compared with control, indicating more synthesis of ACE proteins. Treatment with curcumin suppressed ACE expression in TAA liver and reversed the toxicity produced. TAA treatment results in higher lipid peroxidation and lower GSH, SOD and CAT than the normal, and this produces oxidative stress in the liver. Cirrhotic conditions were confirmed by serum enzymes (ALT, AST and ALP) as well as histopathological observations. Curcumin treatment reduced oxidative stress in animals by scavenging reactive oxygen species, protecting the anti-oxidant enzymes from being denatured and reducing the oxidative stress marker lipid peroxidation. Curcumin treatment restores hepatocytes, damaged by TAA, and protects liver tissue approaching cirrhosis. © The Author(s) 2014.

Recent studies in learning programming have largely focused on high school and college students; less is known about how young children learn to program. From video data of 20 students using a graphical programming interface, we identified ideas that were shared and evolved through an elementary school classroom. In mapping these ideas and their resulting changes in programs and outputs, we were able to identify the contextual features which contributed to how ideas moved through the classroom as students learned. We suggest this process of idea mapping in visual programming environments as a viable method for understanding collaborative, constructivist learning as well as a context under which experiences can be developed to improve student learning.

Linking clinical registries to administrative claims data enables researchers to capitalize on the specific strengths of each data source with respect to the depth, breadth, and completeness of information. The objectives of this study were to link a health-system-based orthopaedic surgery registry to U.S. Medicare claims data without the use of unique identifiers and to assess the representativeness of the linked records. The registry included clinical data for patients ≥65 years of age who underwent elective, inpatient total ankle arthroplasty (TAA) in a single health system during the period of 2007 through 2012. Registry participants were identified within the Medicare data by linking registry procedures to TAA procedures within the claims data using a combination of procedure date, patient date of birth, and patient sex. We assessed the representativeness of the linked records by comparing them to both unlinked registry records and unlinked Medicare records for TAA procedures. Additionally, we described the availability of postsurgical data for linked records. Of 360 TAA registry participants ≥65 years of age, 280 (77.8%) were matched to a Medicare record; 250 (89.3%) of those 280 participants were matched on the basis of a linking rule that required an exact match for procedure date, date of birth, and sex. The 280 linked records comprised 5.5% of all Medicare TAA procedures among beneficiaries ≥65 years of age enrolled in the fee-for-service Medicare program (n = 5,070). Compared with linked records, unlinked records were more likely to be for patients 65 to 69 years old, but the 2 groups were similar in terms of sex, body mass index, and availability of clinical measurements. Of the linked records, 214 (76.4%) had ≥3 years of postoperative follow-up claims data. Linkage without unique patient identifiers between an orthopaedic registry and Medicare claims data is feasible, allows for assessment of representativeness, and creates a unique resource of

Introductory Overview of Intermediate-luminosity X-ray Objects

NASA Astrophysics Data System (ADS)

Colbert, E. J. M.

2001-05-01

Intermediate-luminosity X-ray Objects (IXOs) are defined as compact objects having X-ray luminosities between those of X-ray binaries and low-luminosity AGNs (i.e., 1039.0 erg s-1 < ~ LX [IXOs] < ~ 1041.0 erg s-1). It is not currently known if these objects are intermediate-mass (M ~ 102-104 Msun) black holes accreting near the Eddington limit, near-solar-mass black holes in a super-Eddington state, or are, in some cases, just supermassive black holes accreting at very low rates. However, the first idea has been popularized by recent press coverage. IXOs are quite common (present in about half of spiral galaxies) and are typically found displaced from the optical nucleus, reducing the likelihood that they are low-luminosity AGN. Nearly all of our knowledge of these objects comes from X-ray observations, as observations of optical, NIR and radio counterparts are not widely known. In this session, we will address (1) the phenomenology of the objects, (2) possible geometry and accretion mechanisms for these objects (i.e., are they more similar to black hole X-ray binaries or AGNs), (3) the central black hole masses, and (4) the formation mechanism for these black holes, if they are of intermediate mass. In this talk, I will focus primarily on giving background information of these fascinating objects.

Investigating Elementary Teachers' Thinking About and Learning to Notice Students' Science Ideas

NASA Astrophysics Data System (ADS)

Luna, Melissa Jo

Children naturally use observations and everyday thinking to construct explanations as to why phenomena happen in the world. Science instruction can benefit by starting with these ideas to help children build coherent scientific understandings of how the physical world works. To do so, science teaching must involve attending to students' ideas so that those ideas become the basis for learning. Yet while science education reform requires teachers to pay close attention to their students' ideas, we know little about what teachers think this means in practice. To examine this issue, my dissertation research is two-fold. First, I examine teacher thinking by investigating how teachers understand what it means to pay attention to students' science ideas. Specifically, using new digital technology, three participating teachers captured moments of student thinking in the midst of instruction. Analysis of these moments reveals that teachers capture many different kinds of moments containing students' ideas and think about students' science ideas in different ways at different times. In particular, these three teachers most often think about students' ideas as being (a) from authority, (b) from experience, and (c) under construction. Second, I examine teacher learning through the development of an innovative science teaching video club model. The model differs from previous research on video clubs in several key ways in an attempt to focus teachers on student thinking in a sustained way. I investigate the ways in which this model was effective for engaging teachers in noticing and making sense of their students' science ideas during one implementation. Results indicate that teachers talked about student thinking early, often, and in meaningful ways. Science education leaders have recognized the potential of science teaching video clubs as a form of professional development, and the model presented in this work promotes the conditions for successful teacher learning.

New product ideas: from the mind to the market.

PubMed

Toter, K M

If you have an idea for a new product, consider the following steps. Carefully research your product idea before looking for a company or research office to market it. You will save yourself a considerable amount of time and effort if you find that the same or a similar device is already on the market. Check to see if you signed a patent policy when you were hired. Some employers claim rights to discoveries made on the job. Obtain legal advice. A lawyer can provide information about nondisclosure agreements, patents, and other forms of protection for the inventor. Most major cities have a lawyer referral service offered through the bar association. They will answer some questions and will provide names of lawyers who specialize in that area of law. Before submitting your product idea to a company for evaluation, evaluate the company. Make sure they are a reputable medical supply company. Find out such things as how they plan to research your idea, and what your share as the inventor will be. Take notes when surveying professionals from other hospitals about your idea. The information gathered can be used when writing your product proposal. Submitting a list of hospitals experiencing problems that your device could solve is a good selling point. Keep records of all phone conversations and copies of all written correspondence between the inventor and the company or research office. Always try to get commitments in writing, and keep the lines of communication open. Major cities offer different sources that the inventor can turn to for help. Check around. Do not be afraid to ask questions. If you have carefully researched your product idea and really believe it will improve patient care, go for it! It might be a long hard road, and despite all your efforts, the device may never make it to the market. But if it does, seeing your device used to enhance patient care makes it all worthwhile.

Creativity is considered key to human prosperity, yet the neurocognitive principles underlying creative performance, and their development, are still poorly understood. To fill this void, we examined the neural correlates of divergent thinking in adults (25–30 years) and adolescents (15–17 years). Participants generated alternative uses (AU) or ordinary characteristics (OC) for common objects while brain activity was assessed using fMRI. Adults outperformed adolescents on the number of solutions for AU and OC trials. Contrasting neural activity for AU with OC trials revealed increased recruitment of left angular gyrus, left supramarginal gyrus, and bilateral middle temporal gyrus in both adults and adolescents. When only trials with multiple AU were included in the analysis, participants showed additional left inferior frontal gyrus (IFG)/middle frontal gyrus (MFG) activation for AU compared to OC trials. Correspondingly, individual difference analyses showed a positive correlation between activations for AU relative to OC trials in left IFG/MFG and divergent thinking performance and activations were more pronounced in adults than in adolescents. Taken together, the results of this study demonstrated that creative idea generation involves recruitment of mainly left lateralized parietal and temporal brain regions. Generating multiple creative ideas, a hallmark of divergent thinking, shows additional lateral PFC activation that is not yet optimized in adolescence. PMID:24416008

Severe Acute Liver Failure (ALF) is a life-threatening clinical syndrome characterized by hepatocyte necrosis, loss of hepatic architecture, and impairment of liver functions. One of the main causes of ALF is hepatotoxicity from chemical agents, which damage hepatocytes and result in increase of reactive oxygen species. The vitamin E isoform is the one with the strongest biological antioxidant activity. To evaluate the antioxidant effect of vitamin E in this ALF model. We used 56 rats (mean weight of 300 g) divided into eight groups, four groups assessed at 24 hours and 4 assessed at 48 hours after induction: control group (CO); Vitamin E (Vit. E); Thioacetamide (TAA) and Thioacetamide + Vitamina E (TAA+Vit.E). Rats were submitted to injections of thioacetamide (400 mg/kg i.p.) at baseline and 8 hours later. Vitamin E (100 mg/kg ip) was administered 30 minutes after the second dose of thioacetamide. The 48-hour group rats received two additional doses of vitamin E (24h and 36h). At 24h or 48 hours after the administration of the first dose of TAA, rats were weighed and anesthetized and their blood sampled for evaluation of liver integrity through enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Liver tissue was sampled for assessment of lipid peroxidation (LPO) by the technique TBARS, antioxidant enzymes SOD, CAT, GPx and GST activity, levels of the NO 2 /NO 3 and histology by H&E in two times. The results were expressed as mean ± standard deviation and statistically analyzed by ANOVA followed by Student-Newman-Keuls, with P <0.05 considered as significant. After treatment with vitamin E, we observed a reduction in liver enzymes AST (U/L) (101.32±19.45 in 24 hours and 97.85±29.65 in 48 hours) related to the TAA group (469.56± 0.69 in 24 hours and 598.23±55.45 in 48 hours) and ALT (U/L) (76.59±8.56 in 24 hours and 68.47±6.49 in 48 hours) compared to the TAA group (312.21±10.23 in 24 hours and 359.15±17.58 in 48 hours).

Assessing educational outcomes in high-risk populations is crucial for defining long-term outcomes. As standardized tests are costly and time-consuming, we assessed the use of the Teacher Academic Attainment Scale (TAAS) as an outcome measure. Three hundred and forty three children in mainstream schools aged 10 to 11 years (144 males, 199 females; 190 extremely preterm and 153 term; mean age 10 y 9 mo, SD 5.5 mo, range 9 y 8 mo-12 y 3 mo) were assessed using the reading and mathematics scales of the criterion standard Wechsler Individual Achievement Test, 2nd (UK) edition (WIAT-II). Class teachers completed the TAAS, a seven-item questionnaire for assessing academic attainment. The TAAS was also completed at 6 years of age for 266 children. Cronbach's alpha 0.95 indicated excellent internal consistency, and the correlation between TAAS scores at 6 and 11 years indicated good test-retest reliability (r=0.77, p<0.001). Significantly higher TAAS scores for term vs preterm children demonstrated discriminative validity. TAAS scores at 6 and 11 years were significantly correlated with WIAT-II reading (r=0.69 and 0.75, p<0.001) and mathematics (r=0.75 and 0.82, p<0.001) scores, demonstrating good predictive and concurrent validity respectively. TAAS scores of <2.5 were good predictors of learning difficulties. The TAAS is a brief, psychometrically sound teacher-report of academic attainment that yields continuous and categorical outcomes. It provides a cost- and time-efficient outcome measure for large-scale studies. © The Authors. Developmental Medicine & Child Neurology © 2012 Mac Keith Press.

A Trimeric Lipoprotein Assists in Trimeric Autotransporter Biogenesis in Enterobacteria*

Trimeric autotransporter adhesins (TAAs) are important virulence factors of many Gram-negative bacterial pathogens. TAAs form fibrous, adhesive structures on the bacterial cell surface. Their N-terminal extracellular domains are exported through a C-terminal membrane pore; the insertion of the pore domain into the bacterial outer membrane follows the rules of β-barrel transmembrane protein biogenesis and is dependent on the essential Bam complex. We have recently described the full fiber structure of SadA, a TAA of unknown function in Salmonella and other enterobacteria. In this work, we describe the structure and function of SadB, a small inner membrane lipoprotein. The sadB gene is located in an operon with sadA; orthologous operons are only found in enterobacteria, whereas other TAAs are not typically associated with lipoproteins. Strikingly, SadB is also a trimer, and its co-expression with SadA has a direct influence on SadA structural integrity. This is the first report of a specific export factor of a TAA, suggesting that at least in some cases TAA autotransport is assisted by additional periplasmic proteins. PMID:24369174

To examine the effects of aspirin and enoxaparin on liver function, coagulation index and histopathology in a rat model of liver fibrosis. METHODS Forty-five male Sprague-Dawley rats were randomly divided into the control group (n = 5) and model group (n = 40). Thioacetamide (TAA) was used to induce liver fibrosis in the model group. TAA-induced fibrotic rats received TAA continuously (n = 9), TAA + low-dose aspirin (n = 9), TAA + high-dose aspirin (n = 9) or TAA + enoxaparin (n = 9) for 4 wk. All rats were euthanized after 4 wk, and both hematoxylin-eosin and Masson staining were performed to observe pathological changes in liver tissue. Liver fibrosis was assessed according to the METAVIR score. Compared with untreated cirrhotic controls, a significant improvement in fibrosis grade was observed in the low-dose aspirin, high-dose aspirin and enoxaparin treated groups, especially in the high-dose aspirin treated group. Alanine aminotransferase and total bilirubin were higher, albumin was lower and both prothrombin time and international normalized ratio were prolonged in the four treatment groups compared to controls. No significant differences among the four groups were observed. Aspirin and enoxaparin can alleviate liver fibrosis in this rat model.

Developing knowledge intensive ideas in engineering education: the application of camp methodology

NASA Astrophysics Data System (ADS)

Heidemann Lassen, Astrid; Løwe Nielsen, Suna

2011-11-01

Background: Globalization, technological advancement, environmental problems, etc. challenge organizations not just to consider cost-effectiveness, but also to develop new ideas in order to build competitive advantages. Hence, methods to deliberately enhance creativity and facilitate its processes of development must also play a central role in engineering education. However, so far the engineering education literature provides little attention to the important discussion of how to develop knowledge intensive ideas based on creativity methods and concepts. Purpose: The purpose of this article is to investigate how to design creative camps from which knowledge intensive ideas can unfold. Design/method/sample: A framework on integration of creativity and knowledge intensity is first developed, and then tested through the planning, execution and evaluation of a specialized creativity camp with focus on supply chain management. Detailed documentation of the learning processes of the participating 49 engineering and business students is developed through repeated interviews during the process as well as a survey. Results: The research illustrates the process of development of ideas, and how the participants through interdisciplinary collaboration, cognitive flexibility and joint ownership develop highly innovative and knowledge-intensive ideas, with direct relevance for the four companies whose problems they address. Conclusions: The article demonstrates how the creativity camp methodology holds the potential of combining advanced academic knowledge and creativity, to produce knowledge intensive ideas, when the design is based on ideas of experiential learning as well as creativity principles. This makes the method a highly relevant learning approach for engineering students in the search for skills to both develop and implement innovative ideas.

Improving college students' evaluation of text learning using idea-unit standards.

PubMed

Dunlosky, John; Hartwig, Marissa K; Rawson, Katherine A; Lipko, Amanda R

2011-03-01

When recalling key definitions from class materials, college students are often overconfident in the quality of their responses. Even with commission errors, they often judge that their response is entirely or partially correct. To further understand this overconfidence, we investigated whether idea-unit judgements would reduce overconfidence (Experiments 1 and 2) and whether students inflated their scores because they believed that they knew answers but just responded incorrectly (Experiment 2). College students studied key-term definitions and later attempted to recall each definition when given the key term (e.g., What is the availability heuristic?). All students judged the quality of their recall, but some were given a full-definition standard to use, whereas other students first judged whether their response included each of the individual ideas within the corresponding correct answer. In Experiment 1, making these idea-unit judgements reduced overconfidence for commission errors. In Experiment 2, some students were given the correct definitions and graded other students' responses, and some students generated idea units themselves before judging their responses. Students were overconfident even when they graded other students' responses, and, as important, self-generated idea units for each definition also reduced overconfidence in commission errors. Thus, overconfidence appears to result from difficulties in evaluating the quality of recall responses, and such overconfidence can be reduced by using idea-unit judgements.

On the three-quarter view advantage of familiar object recognition.

Nonose, Kohei; Niimi, Ryosuke; Yokosawa, Kazuhiko

2016-11-01

A three-quarter view, i.e., an oblique view, of familiar objects often leads to a higher subjective goodness rating when compared with other orientations. What is the source of the high goodness for oblique views? First, we confirmed that object recognition performance was also best for oblique views around 30° view, even when the foreshortening disadvantage of front- and side-views was minimized (Experiments 1 and 2). In Experiment 3, we measured subjective ratings of view goodness and two possible determinants of view goodness: familiarity of view, and subjective impression of three-dimensionality. Three-dimensionality was measured as the subjective saliency of visual depth information. The oblique views were rated best, most familiar, and as approximating greatest three-dimensionality on average; however, the cluster analyses showed that the "best" orientation systematically varied among objects. We found three clusters of objects: front-preferred objects, oblique-preferred objects, and side-preferred objects. Interestingly, recognition performance and the three-dimensionality rating were higher for oblique views irrespective of the clusters. It appears that recognition efficiency is not the major source of the three-quarter view advantage. There are multiple determinants and variability among objects. This study suggests that the classical idea that a canonical view has a unique advantage in object perception requires further discussion.

Development of IDEA product for GOES-R aerosol data

2009-08-01

The NOAA GOES-R Advanced Baseline Imager (ABI) will have nearly the same capabilities as NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) to generate multi-wavelength retrievals of aerosol optical depth (AOD) with high temporal and spatial resolution, which can be used as a surrogate of surface particulate measurements such as PM2.5 (particulate matter with diameter less than 2.5 μm). To prepare for the launch of GOES-R and its application in the air quality forecasting, we have transferred and enhanced the Infusing satellite Data into Environmental Applications (IDEA) product from University of Wisconsin to NOAA NESDIS. IDEA was created through a NASA/EPA/NOAA cooperative effort. The enhanced IDEA product provides near-real-time imagery of AOD derived from multiple satellite sensors including MODIS Terra, MODIS Aqua, GOES EAST and GOES WEST imager. Air quality forecast guidance is produced through a trajectory model initiated at locations with high AOD retrievals and/or high aerosol index (AI) from OMI (Ozone Monitoring Instrument). The product is currently running at http://www.star.nesdis.noaa.gov/smcd/spb/aq/. The IDEA system will be tested using the GOES-R ABI proxy dataset, and will be ready to operate with GOES-R aerosol data when GOES-R is launched.

Creation of the information model of the building object of cultural heritage including a full complex of information on an object is offered: historical and archival, legal, technical, administrative, etc. The 3D model of an object of cultural heritage with color marking of elements on degree of wear and a first priority of carrying out repair will become one of components of model. This model will allow to estimate visually technical condition of the building in general and to gain general idea about scales of necessary repair and construction actions that promotes improvement of quality of operation of an object, and also simplifies and accelerates processing of information and in need of a memorial building assessment as subject to investment.

To compare the technical feasibility and hemodynamic alterations during antegrade transcardiac access routes vs conventional transfemoral access (TFA) for endovascular treatment of the ascending aorta in a porcine model. Antegrade transseptal access (TSA), transapical access (TAA), and TFA were used for implantation of custom-made endografts into the ascending aorta under fluoroscopy (6 pigs each). Hemodynamic parameters, myocardial and cerebral blood flow, and carotid artery blood flow were evaluated during baseline (T1), sheath advancement (T2), after sheath retraction (T3), and after endograft deployment (T4). Endograft deployment was feasible in all animals; all coronary arteries remained patent. Hemodynamic parameters were comparable in all 3 study groups during all measurements. During T2, transient hemodynamic alteration occurred in all groups, with transient severe valve insufficiency in TSA and TAA reflected by the higher pulmonary to mean arterial pressure ratio (p<0.05) as compared with TFA. Values stabilized again at T3 and remained stable until T4. The innominate artery was partially occluded in 4 (TSA), 3 (TAA), and 5 (TFA) animals. There was no deterioration of myocardial or cerebral perfusion during the procedures. Endograft deployment and fluoroscopy times during TAA were shorter than in TSA and TFA. TSA, TFA, and TAA to the ascending aorta are feasible for endograft delivery to the ascending aorta in a porcine model. Transient hemodynamic instability in TSA and TAA recovered to near preoperative values. TAA appeared technically easier. © The Author(s) 2015.

Dendritic cells for active anti-cancer immunotherapy: targeting activation pathways through genetic modification.

PubMed

Breckpot, Karine; Escors, David

2009-12-01

Tumour immunotherapy has become a treatment modality for cancer, harnessing the immune system to recognize and eradicate tumour cells specifically. It is based on the expression of tumour associated antigens (TAA) by the tumour cells and aims at the induction of TAA-specific effector T cell responses, whilst overruling various mechanisms that can hamper the anti-tumour immune response, e.g. regulatory T cells (Treg). (Re-) activation of effector T cells requires the completion of a carefully orchestrated series of specific steps. Particularly important is the provision of TAA presentation and strong stimulatory signals, delivered by co-stimulatory surface molecules and cytokines. These can only be delivered by professional antigen-presenting cells, in particular dendritic cells (DC). Therefore, DC need to be loaded with TAA and appropriately activated. It is not surprising that an extensive part of DC research has focused on the delivery of both TAA and activation signals to DC, developing a one step approach to obtain potent stimulatory DC. The simultaneous delivery of TAA and activation signals is therefore the topic of this review, emphasizing the role of DC in mediating T cell activation and how we can manipulate DC for the pill-pose of enhancing tumour immunotherapy. As we gain a better understanding of the molecular and cellular mechanisms that mediate induction of TAA-specific T cells, rational approaches for the activation of T cell responses can be developed for the treatment of cancer.

Alternative paradigm for the cosmic objects formation: New prospects

NASA Astrophysics Data System (ADS)

Harutyunian, Haik A.

2017-12-01

We consider here briefly the cosmogonic concept suggested by Viktor Ambartsumian in the last century for explaining the formation of cosmic objects. He grounded his concept using the observational facts available in 40s-60s of the last century. The analysis of observational data allowed him to conclude that cosmic objects formation takes place up to nowadays. The second and more "heretical" conclusion he arrived at persuades that the origination and further evolution of cosmic objects goes on in course of gradual decay of proto-stellar matter at all hierarchical levels. We argue that this approach appeared first time in Ambartsumian's papers devoted to the problems of quantum electrodynamics. Later on his concept on objects formation due to decay of protostellar dense matter was rejected because the known laws of physics do not allow existence of huge masses consisted of superdense matter. We bring to the readers' attention, that the discovery of dark energy changes the situation drastically and opens new rooms for the ideas forgotten by the scientific community.

Mistakes and missed opportunities regarding cosmetic surgery and conscientious objection.

PubMed

Saad, Toni C

2017-04-24

In her paper 'Cosmetic surgery and conscientious objection', Minerva rightly identifies cosmetic surgery as an interesting test case for the question of conscientious objection in medicine. Her treatment of this important subject, however, seems problematic. It is argued that Minerva's suggestion that a doctor has a prima facie duty to satisfy patient preferences even against his better clinical judgment, which we call Patient Preference Absolutism, must be regarded with scepticism. This is because (1) it overlooks an important distinction regarding autonomy's meaning and place in clinical practice, and (2) it makes obsolete the important concepts of expert clinical judgment and beneficence. Finally, we discuss two ideas which emerge from consideration of cosmetic surgery in relation to conscientious objection. These are the possible analogy between clinical judgment and conscientious objection, and the possible role the goals of medicine can play in defining the scope of conscientious objection.

Breathing pattern and thoracoabdominal asynchrony in horses with chronic obstructive and inflammatory lung disease.

PubMed

Haltmayer, E; Reiser, S; Schramel, J P; van den Hoven, R

2013-10-01

The aim of the study was to show that changes in thoracoabdominal asynchrony (TAA) between quiet breathing and CO2-induced hyperpnoea can be used to differentiate between horses with healthy airways and those suffering from inflammatory airway disease (IAD) or recurrent airway obstruction (RAO). The level of TAA was displayed by the Pearson's correlation coefficient (PCC) of thoracic and abdominal signals, generated by respiratory ultrasonic plethysmography (RUP) during quiet breathing and hyperpnoea. Changes in TAA were expressed as the quotient of the PCCs (PCCQ) during normal breathing and hyperpnoea. Horses with RAO and IAD showed significant higher median PCCQ than healthy horses. Median PCCQ of horses with RAO and IAD was not significantly different. Horses affected by a pulmonary disorder showed lower TAA compared to the control group. This study suggests that TAA provides a useful parameter to differentiate horses with RAO and IAD from healthy horses. Copyright © 2013 Elsevier Ltd. All rights reserved.

Therapeutic assessment with an adolescent: choosing connections over substances.

PubMed

Austin, Cynthia A; Krumholz, Lauren S; Tharinger, Deborah J

2012-01-01

This case study provides an in-depth example of a comprehensive therapeutic assessment with an adolescent (TA-A) and his parents. The TA-A addressed parental concerns about their son's drug experimentation as well as the adolescent's own private questions about his distinctiveness from others, all set against a backdrop of ongoing parental conflict and poor communication. The TA-A process and how it is specifically tailored to balance the needs of adolescents and their parents is discussed. Subsequently, each step of TA-A is illustrated through the case study. Research findings at the conclusion of the assessment and at follow-up indicated significant decreases in internalizing symptomology and school problems, increases in self-esteem and self-reliance, and improved family functioning as reported by the adolescent. At follow-up, the father spoke of developing a more assertive parenting approach and successful follow-through on recommendations. This case study provides a template for clinicians interested in conducting TA-A.

Elementary students' multiple representations of their ideas about air

NASA Astrophysics Data System (ADS)

Gravel, Brian Edward

This dissertation explores how students generate multiple external representations of their ideas about air, an "invisible" substance. External representations can serve a powerful role in placing students' ideas into the external world for reflection and abstraction. When provided the opportunity to represent their understandings of science in different ways, students generate increasingly coherent explanations of what they observe, including developing ideas about mechanisms that describe cause and effect. In this qualitative study, extended clinical interviews were conducted with twelve fifth-grade students from an urban public charter school. In study was designed to investigate students' ideas about air in the context of a linked-syringe device with the support of multiple representations. Students were given the opportunity to produce representations and to offer verbal explanations of the behavior of the syringes in a sequence of three interviews. In the first session, students were introduced to the linked-syringes, and they generated drawings to explain their thinking about air. In the second session, students created stop-motion animations of their explanations for air in the syringes. And in the final session, students built physical devices to demonstrate their ideas about air. Careful analysis of each individual student's trajectory through the microgenetic design and a cross-student analysis reveal that the process of generating multiple representations facilitates how students think and reason about air. Drawings served to organize elements of the linked-syringe problem, providing students with focal points on which to direct their reasoning as they generated more precise explanations. Stop-motion animation supported students' efforts to make sense of processes that change over time, such as compressing the air inside the syringes. And, the construction of physical artifacts prompted students to think about air as a substance, as the activity allowed

Mapping biological ideas: Concept maps as knowledge integration tools for evolution education

NASA Astrophysics Data System (ADS)

Schwendimann, Beat Adrian

Many students leave school with a fragmented understanding of biology that does not allow them to connect their ideas to their everyday lives (Wandersee, 1989; Mintzes, Wandersee, & Novak, 1998; Mintzes, Wandersee, & Novak, 2000a). Understanding evolution ideas is seen as central to building an integrated knowledge of biology (Blackwell, Powell, & Dukes, 2003; Thagard & Findlay, 2010). However, the theory of evolution has been found difficult to understand as it incorporates a wide range of ideas from different areas (Bahar et al., 1999; Tsui & Treagust, 2003) and multiple interacting levels (Wilensky & Resnick, 1999; Duncan & Reiser, 2007; Hmelo-Silver et al., 2007). Research suggests that learners can hold a rich repertoire of co-existing alternative ideas of evolution (for example, Bishop & Anderson, 1990; Demastes, Good, & Peebles, 1996; Evans, 2008), especially of human evolution (for example, Nelson, 1986; Sinatra et al., 2003; Poling & Evans, 2004). Evolution ideas are difficult to understand because they often contradict existing alternative ideas (Mayr, 1982; Wolpert, 1994; Evans, 2008). Research suggests that understanding human evolution is a key to evolution education (for example, Blackwell et al., 2003; Besterman & Baggott la Velle, 2007). This dissertation research investigates how different concept mapping forms embedded in a collaborative technology-enhanced learning environment can support students' integration of evolution ideas using case studies of human evolution. Knowledge Integration (KI) (Linn et al., 2000; Linn et al., 2004) is used as the operational framework to explore concept maps as knowledge integration tools to elicit, add, critically distinguish, group, connect, and sort out alternative evolution ideas. Concept maps are a form of node-link diagram for organizing and representing connections between ideas as a semantic network (Novak & Gowin, 1984).

Who founded Buddhism? Notes on the psychological effectiveness of religious objects.

PubMed

Black, David M

2017-04-01

Starting with an outline of Buddhist history from a psychoanalytic perspective, this paper uses ideas from philosophy and psychoanalysis to consider the nature of the psychological effectiveness of religious objects. It suggests that the development of the devotional cult of Buddhas 'without form' such as Amitābha, at-first-glance surprising when juxtaposed with the founding vision of Gautama Siddhartha, tells us a great deal about the psychological needs that impel the evolution of religious thinking. Distinguishing religious objects from mythological ones, it argues that 'religious objects' are, more specifically, allegorical objects that can be encountered in the second person; that these may not always be well described as 'illusion'; and that they may in some cases be better understood as providing opportunities for experience that, like the transference in psychoanalysis, may have far-reaching psychological impacts.

2015-08-01

The aim of this study was to determine the effect of melatonin on thioacetamide (TAA) induced liver fibrosis in rats. The antifibrotic effects of melatonin were assessed by determining activity indirect markers of fibrosis: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), and proinflammatory cytokines: interleukin 6 (IL-6), interleukin-1beta (IL-1β), tumour necrosis factor alpha (TNF-α), transforming growth factor-beta (TGF-β) and platelet-derived growth factor (PDGF). Parameters of oxidative stress: oxidised glutathione (GSSG), reduced glutathione (GSH) and presaged activity of paraoxonase 1 (PON-1), an antioxidative enzyme were determined. Inflammatory changes and fibrosis extent were evaluated histologically. Experiments were carried out in Wistar rats. Animals were divided into 4 groups: I - controls, water ad libitum for 12 weeks, group II - TAA, 300 mg/L ad libitum for 12 weeks, III - melatonin, 10 mg/kg b.w. intraperitoneally (i.p.) daily for 4 weeks, IV - TAA, 300 mg/L ad libitum for 12 weeks followed by melatonin, 10 mg/kg/b.w. i.p. daily for 4 weeks. Results of serum determinations demonstrated significantly lower activity of AST, ALT and AP in the group receiving TAA followed by melatonin compared to the group receiving only TAA. Immunoenzymatic findings on effect of melatonin on concentration of proinflammatory cytokines confirmed these data. Biochemical examinations in liver homogenates revealed statistically significant improvement (concentration of GSH increases and concentration of GSSG decreases) in animals with TAA-induced liver damage receiving melatonin. Moreover, the activity of PON-1 toward phenyl acetate and paraoxon was increased in liver homogenates and serum in the group receiving TAA followed by melatonin compared to the TAA group without melatonin treatment. Microscopic evaluation disclosed inhibitory effects of melatonin on inflammatory changes and extent of liver fibrosis.

Does leader-affective presence influence communication of creative ideas within work teams?

PubMed

Madrid, Hector P; Totterdell, Peter; Niven, Karen

2016-09-01

Affective presence is a novel, emotion-related personality trait, supported in experimental studies, concerning the extent to which a person makes his or her interaction partners feel the same way (Eisenkraft & Elfenbein, 2010). Applying this concept to an applied teamwork context, we proposed that team-leader-affective presence would influence team members' communication of creative ideas. Multilevel modeling analysis of data from a survey study conducted with teams from a consultancy firm confirmed that team-leader-affective presence interacted with team-member creative idea generation to predict inhibition of voicing their ideas. Specifically, withholding of ideas was less likely when team members generated creative ideas and their team leader had higher positive affective presence or lower negative affective presence. These findings contribute to emotion research by showing affective presence as a trait with interpersonal meaning, which can shape how cognition is translated into social behavior in applied performance contexts, such as teamwork in organizations.

Hb Constant Spring [Hb CS; α142, Term→Gln (TAA>CAA in α2)] is often missed by routine laboratory testing since its mRNA as well as gene product are unstable and presented at a low level in peripheral blood. This study aimed to analyze the efficacy of capillary electrophoresis (CE) and high performance liquid chromatography (HPLC) for detecting and quantifying Hb CS in 19 heterozygotes and 14 homozygotes with Hb CS as well as 10 Hb H-CS disease subjects who were detected by molecular analysis. In the CE electrophoregram, Hb CS was seen at zone 2 and was observed in all samples, while the chromatogram of Hb CS peaks was found in 26.32% heterozygotes, 42.86% homozygotes and 90% Hb H-CS disease subjects, respectively. In addition, the Hb CS levels in each group of subjects quantified by CE were significantly higher than those quantified by HPLC. Based on the CE method, the lowest Hb CS level was found in the heterozygotes, whereas the highest level was found in the Hb H-CS disease patients. Therefore, the CE method was superior to the HPLC method for detecting Hb CS. Furthermore, the level of Hb CS quantified by CE proved useful in screening heterozygotes and homozygotes with Hb CS as well as Hb H-CS disease.

New Ideas for Speech Recognition and Related Technologies

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

Holzrichter, J F

The ideas relating to the use of organ motion sensors for the purposes of speech recognition were first described by.the author in spring 1994. During the past year, a series of productive collaborations between the author, Tom McEwan and Larry Ng ensued and have lead to demonstrations, new sensor ideas, and algorithmic descriptions of a large number of speech recognition concepts. This document summarizes the basic concepts of recognizing speech once organ motions have been obtained. Micro power radars and their uses for the measurement of body organ motions, such as those of the heart and lungs, have been demonstratedmore » by Tom McEwan over the past two years. McEwan and I conducted a series of experiments, using these instruments, on vocal organ motions beginning in late spring, during which we observed motions of vocal folds (i.e., cords), tongue, jaw, and related organs that are very useful for speech recognition and other purposes. These will be reviewed in a separate paper. Since late summer 1994, Lawrence Ng and I have worked to make many of the initial recognition ideas more rigorous and to investigate the applications of these new ideas to new speech recognition algorithms, to speech coding, and to speech synthesis. I introduce some of those ideas in section IV of this document, and we describe them more completely in the document following this one, UCRL-UR-120311. For the design and operation of micro-power radars and their application to body organ motions, the reader may contact Tom McEwan directly. The capability for using EM sensors (i.e., radar units) to measure body organ motions and positions has been available for decades. Impediments to their use appear to have been size, excessive power, lack of resolution, and lack of understanding of the value of organ motion measurements, especially as applied to speech related technologies. However, with the invention of very low power, portable systems as demonstrated by McEwan at LLNL researchers

2018-04-01

Total ankle arthroplasty (TAA) is an increasingly used, effective treatment for end-stage ankle arthritis. Although numerous studies have associated blood transfusion with complications following hip and knee arthroplasty, its effects following TAA are largely unknown. This study uses data from a large, nationally representative database to estimate the association between blood transfusion and inpatient complications and hospital costs following TAA. Using the Nationwide Inpatient Sample (NIS) database from 2004 to 2014, 25 412 patients who underwent TAA were identified, with 286 (1.1%) receiving a blood transfusion. Univariate analysis assessed patient and hospital factors associated with blood transfusion following TAA. Patients requiring blood transfusion were more likely to be female, African American, Medicare recipients, and treated in nonteaching hospitals. Average length of stay for patients following transfusion was 3.0 days longer, while average inpatient cost was increased by approximately 50%. Patients who received blood transfusion were significantly more likely to suffer from congestive heart failure, peripheral vascular disease, hypothyroidism, coagulation disorder, or anemia. Acute renal failure was significantly more common among patients receiving blood transfusion ( P < .001). Blood transfusions following TAA are infrequent and are associated with multiple medical comorbidities, increased complications, longer hospital stays, and increased overall cost.

2013-01-01

Amino acid profile is a key aspect of human milk (HM) protein quality. We report a systematic review of total amino acid (TAA) and free amino acid (FAA) profiles, in term and preterm HM derived from 13 and 19 countries, respectively. Of the 83 studies that were critically reviewed, 26 studies with 3774 subjects were summarized for TAA profiles, while 22 studies with 4747 subjects were reviewed for FAA. Effects of gestational age, lactation stage, and geographical region were analyzed by Analysis of Variance. Data on total nitrogen (TN) and TAA composition revealed general inter-study consistency, whereas FAA concentrations varied among studies. TN and all TAA declined in the first two months of lactation and then remained relatively unchanged. In contrast, the FAA glutamic acid and glutamine increased, peaked around three to six months, and then declined. Some significant differences were observed for TAA and FAA, based on gestational age and region. Most regional TAA and FAA data were derived from Asia and Europe, while information from Africa was scant. This systematic review represents a useful evaluation of the amino acid composition of human milk, which is valuable for the assessment of protein quality of breast milk substitutes. PMID:24288022

Conceptual preparation mechanisms such as novel idea generation and selection from amongst competing alternatives are critical for language production and may contribute to age-related language deficits. This study investigated whether older adults show diminished idea generation and selection abilities, compared to younger adults. Twenty younger (18-35 years) and 20 older (60-80 years) adults completed two novel experimental tasks, an idea generation task and a selection task. Older participants were slower than younger participants overall on both tasks. Importantly, this difference was more pronounced for task conditions with greater demands on generation and selection. Older adults were also significantly reduced on a semantic, but not phonemic, word fluency task. Overall, the older group showed evidence of age-related decline specific to idea generation and selection ability. This has implications for the message formulation stage of propositional language decline in normal aging.

Narrative ideas for consulting with communities and organizations: ripples from the gatherings.

PubMed

Freedman, Jill; Combs, Gene

2009-09-01

This paper reviews Michael White's early work with communities and extends ideas and practices from that work into the realm of consulting with organizations. We draw on Michael's writing and the records of two specific projects, as well as the recollections of team members in those projects, to describe how ideas and practices that were originally developed in working with individuals and families came to be applied in community settings. Specifically, we show how the central intention of the work is to use narrative ideas and practices in ways that allow communities to articulate, appreciate, document, utilize, and share their own knowledges of life and skills of living. We discuss the basic narrative ideas of stories, double listening, telling and retelling, making documents, and linking lives through shared purposes. For these projects, the teams developed structures that made it possible to use the basic idea with whole communities. We show how this work with communities has offered inspiration and ideas for our work in consulting to organizations. Finally, we describe and illustrate a particular way of working with organizations that carries the spirit of Michael's community work into situations requiring shorter blocks of time and more limited commitments than the original community contexts.

Rural and urban Ugandan primary school children's alternative ideas about animals

NASA Astrophysics Data System (ADS)

Otaala, Justine

This study examined rural and urban Ugandan primary children's alternative ideas about animals through the use of qualitative research methods. Thirty-six children were selected from lower, middle, and upper primary grades in two primary schools (rural and urban). Data were collected using interview-about-instance technique. Children were shown 18 color photographs of instances and non-instances of familiar animals and asked to say if the photographed objects were animals or not. They were then asked to give reasons to justify their answers. The interviews were audiotaped and transcribed. The results indicate that children tended to apply the label "animal" to large mammals, usually found at home, on the farm, in the zoo, and in the wild. Humans were not categorized as animals, particularly by children in the lower grades. Although the children in upper grades correctly identified humans as animals, they used reasons that were irrelevant to animal attributes and improperly derived from the biological concept of evolution. Many attributes children used to categorize instances of animals were scientifically unacceptable and included superficial features, such as body outline, anatomical features (body parts), external features (visual cues), presence or absence and number of appendages. Movement and eating (nutrition) were the most popular attributes children used to identify instances of animals. The main differences in children's ideas emanated from the reasons used to identify animals. Older rural children drew upon their cultural and traditional practices more often than urban children. Anthropomorphic thinking was predominant among younger children in both settings, but diminished with progression in children's grade levels. Some of the implications of this study are: (1) teachers, teacher educators and curriculum developers should consider learners' ideas in planning and developing teaching materials and interventions. (2) Teachers should relate humans to other

Helping students revise disruptive experientially supported ideas about thermodynamics: Computer visualizations and tactile models

Clark, Douglas; Jorde, Doris

2004-01-01

This study analyzes the impact of an integrated sensory model within a thermal equilibrium visualization. We hypothesized that this intervention would not only help students revise their disruptive experientially supported ideas about why objects feel hot or cold, but also increase their understanding of thermal equilibrium. The analysis synthesizes test data and interviews to measure the impact of this strategy. Results show that students in the experimental tactile group significantly outperform their control group counterparts on posttests and delayed posttests, not only on tactile explanations, but also on thermal equilibrium explanations. Interview transcripts of experimental and control group students corroborate these findings. Discussion addresses improving the tactile model as well as application of the strategy to other science topics. The discussion also considers possible incorporation of actual kinetic or thermal haptic feedback to reinforce the current audio and visual feedback of the visualization. This research builds on the conceptual change literature about the nature and role of students' experientially supported ideas as well as our understanding of curriculum and visualization design to support students in learning about thermodynamics, a science topic on which students perform poorly as shown by the National Assessment of Educational Progress (NAEP) and Third International Mathematics and Science Study (TIMSS) studies.

IDEA: Planning at the Core of Autonomous Reactive Agents

2002-01-01

Several successful autonomous systems are separated into technologically diverse functional layers operating at different levels of abstraction. This diversity makes them difficult to implement and validate. In this paper, we present IDEA (Intelligent Distributed Execution Architecture), a unified planning and execution framework. In IDEA a layered system can be implemented as separate agents, one per layer, each representing its interactions with the world in a model. At all levels, the model representation primitives and their semantics is the same. Moreover, each agent relies on a single model, plan database, plan runner and on a variety of planners, both reactive and deliberative. The framework allows the specification of agents that operate, within a guaranteed reaction time and supports flexible specification of reactive vs. deliberative agent behavior. Within the IDEA framework we are working to fully duplicate the functionalities of the DS1 Remote Agent and extend it to domains of higher complexity than autonomous spacecraft control.

Controlling the motion of multiple objects on a Chladni plate

NASA Astrophysics Data System (ADS)

Zhou, Quan; Sariola, Veikko; Latifi, Kourosh; Liimatainen, Ville

2016-09-01

The origin of the idea of moving objects by acoustic vibration can be traced back to 1787, when Ernst Chladni reported the first detailed studies on the aggregation of sand onto nodal lines of a vibrating plate. Since then and to this date, the prevailing view has been that the particle motion out of nodal lines is random, implying uncontrollability. But how random really is the out-of-nodal-lines motion on a Chladni plate? Here we show that the motion is sufficiently regular to be statistically modelled, predicted and controlled. By playing carefully selected musical notes, we can control the position of multiple objects simultaneously and independently using a single acoustic actuator. Our method allows independent trajectory following, pattern transformation and sorting of multiple miniature objects in a wide range of materials, including electronic components, water droplets loaded on solid carriers, plant seeds, candy balls and metal parts.

Navigating systems ideas for health practice: Towards a common learning device.

PubMed

Reynolds, Martin; Sarriot, Eric; Swanson, Robert Chad; Rusoja, Evan

2018-06-01

Systems thinking and reference to complexity science have gained currency in health sector practice and research. The extent to which such ideas might represent a mere passing fad or might more usefully be mobilized to tackle wicked problems in health systems is a concern underpinning this paper. Developing the usefulness of the systems idea requires appreciating how systems ideas are used essentially as constructs conceptually bounded by practitioners. Systems are used for purposes of understanding and engaging the reality of health issues, with the intent of transforming the reality into one that is more manageable, equitable, and sustainable. We examine some manifestations of the systems idea in health practice and the traditions of systems practice that variously make use of them. This provides a platform for proposing a systems thinking in (health) practice heuristic: a learning device supporting how different tools and methods can address "wicked problems" in health praxis. The device is built on the use of "conversation" as a metaphor to help practitioners use systems ideas in tandem with existing disciplinary and professional skills and methods. We consider how the application of the heuristic requires, and helps to develop, human characteristics of humility, empathy, and recognition of fallibility. © 2018 John Wiley & Sons, Ltd.

Utopic ideas of cure and joint exploration in psychoanalytic supervision.

PubMed

Werbart, Andrzej

2007-12-01

The idea of the decisive and complete cure is deeply rooted in our unconscious and in the sacral roots of symbolic healing. Double sets of private theories of cure can frequently be found among patients in psychoanalysis and their analysts. The utopian cure involves a profound transformation of the personality by way of deep regression. The idea of an attainable and more limited cure includes new ways of managing old problems. The actual ongoing treatment is then seen as the 'next-best solution'. The utopian fantasy of creating 'the new person' by means of 'proper' psychoanalysis or analytic training has far-reaching consequences for psychoanalytic education and supervision. Our awareness of the inevitable temptation in the 'utopian state of mind' can help us to trace and focus on utopic elements in the supervisory process. Exploration of utopic ideas of all the three parties involved can itself be a fruitful and stimulating way of working in supervision. An important aim of psychoanalytic supervision is to promote a distinct state of mind that can counterbalance utopic ideas and counteract the phenomenon of a 'false analytic self'.

Ideas for Future GPS Timing Improvements

NASA Technical Reports Server (NTRS)

Hutsell, Steven T.

1996-01-01

Having recently met stringent criteria for full operational capability (FOC) certification, the Global Positioning System (GPS) now has higher customer expectations than ever before. In order to maintain customer satisfaction, and the meet the even high customer demands of the future, the GPS Master Control Station (MCS) must play a critical role in the process of carefully refining the performance and integrity of the GPS constellation, particularly in the area of timing. This paper will present an operational perspective on several ideas for improving timing in GPS. These ideas include the desire for improving MCS - US Naval Observatory (USNO) data connectivity, an improved GPS-Coordinated Universal Time (UTC) prediction algorithm, a more robust Kalman Filter, and more features in the GPS reference time algorithm (the GPS composite clock), including frequency step resolution, a more explicit use of the basic time scale equation, and dynamic clock weighting. Current MCS software meets the exceptional challenge of managing an extremely complex constellation of 24 navigation satellites. The GPS community will, however, always seek to improve upon this performance and integrity.

Modeling and predicting abstract concept or idea introduction and propagation through geopolitical groups

Jaenisch, Holger M.; Handley, James W.; Hicklen, Michael L.

2007-04-01

This paper describes a novel capability for modeling known idea propagation transformations and predicting responses to new ideas from geopolitical groups. Ideas are captured using semantic words that are text based and bear cognitive definitions. We demonstrate a unique algorithm for converting these into analytical predictive equations. Using the illustrative idea of "proposing a gasoline price increase of 1 per gallon from 2" and its changing perceived impact throughout 5 demographic groups, we identify 13 cost of living Diplomatic, Information, Military, and Economic (DIME) features common across all 5 demographic groups. This enables the modeling and monitoring of Political, Military, Economic, Social, Information, and Infrastructure (PMESII) effects of each group to this idea and how their "perception" of this proposal changes. Our algorithm and results are summarized in this paper.

Health care system change and the cross-border transfer of ideas: influence of the Dutch model on the 2007 German health reform.

PubMed

Leiber, Simone; Gress, Stefan; Manouguian, Maral-Sonja

2010-08-01

To increase understanding of the cross-border transfer of ideas through a case study of the 2007 German health reform, this article draws on Kingdon's approach of streams and follows two main objectives: first, to understand the extent to which the German health reform was actually influenced by the Dutch model and, second, in theoretical terms, to inform inductively on how ideas from abroad enter government agendas. The results show that the streams of problem recognition and policy proposals have not been predominantly influenced by the cross-border transfer of ideas from the Netherlands to Germany. The Dutch experience was taken into consideration only after a policy window opened by a shift in politics in the third, the political, stream: the change of government in 2005. In many respects, the way Germany learned from the Netherlands in this case sharply contrasts with an image of solving policy problems by either lesson drawing or transnational deliberation. Instead, the process was dominated by problem solving in the sphere of politics, that is, finding a way to prove the grand coalition was capable of acting.

Persistent Identifiers as Boundary Objects

NASA Astrophysics Data System (ADS)

Parsons, M. A.; Fox, P. A.

2017-12-01

In 1989, Leigh Star and Jim Griesemer defined the seminal concept of `boundary objects'. These `objects' are what Latour calls `immutable mobiles' that enable communication and collaboration across difference by helping meaning to be understood in different contexts. As Star notes, they are a sort of arrangement that allow different groups to work together without (a priori) consensus. Part of the idea is to recognize and allow for the `interpretive flexibility' that is central to much of the `constructivist' approach in the sociology of science. Persistent Identifiers (PIDs) can clearly act as boundary objects, but people do not usually assume that they enable interpretive flexibility. After all, they are meant to be unambiguous, machine-interpretable identifiers of defined artifacts. In this paper, we argue that PIDs can fill at least two roles: 1) That of the standardized form, where there is strong agreement on what is being represented and how and 2) that of the idealized type, a more conceptual concept that allows many different representations. We further argue that these seemingly abstract conceptions actually help us implement PIDs more effectively to link data, publications, various other artifacts, and especially people. Considering PIDs as boundary objects can help us address issues such as what level of granularity is necessary for PIDs, what metadata should be directly associated with PIDs, and what purpose is the PID serving (reference, provenance, credit, etc.). In short, sociological theory can improve data sharing standards and their implementation in a way that enables broad interdisciplinary data sharing and reuse. We will illustrate this with several specific examples of Earth science data.

'Swab racks are an old fashioned idea'.

Mumford, M

1991-12-01

Mary Mumford, theatre sister at the Princes of Wales Hospital, Bridgend, was asked to speak in a short debate at an NATN branch meeting, supporting the motion that 'swab racks are an old fashioned idea'. Although she did not like swab racks she had not attempted thus far to do anything about them. In the event, she actually lost the debate--not in principle but because she could offer no effective alternative method of checking swabs. Having been given the incentive, a trial is now being conducted in her hospital similar to that described by Paul Wicker. This is the case presented by Mary Mumford supporting the following motion ... 'that swab racks are an old fashioned idea, which cause more potential problems due to exposure of blood than is proven to be safe in today's theatre environment'.

Looking for ideas: Eye behavior during goal-directed internally focused cognition☆

PubMed Central

Walcher, Sonja; Körner, Christof; Benedek, Mathias

2017-01-01

Humans have a highly developed visual system, yet we spend a high proportion of our time awake ignoring the visual world and attending to our own thoughts. The present study examined eye movement characteristics of goal-directed internally focused cognition. Deliberate internally focused cognition was induced by an idea generation task. A letter-by-letter reading task served as external task. Idea generation (vs. reading) was associated with more and longer blinks and fewer microsaccades indicating an attenuation of visual input. Idea generation was further associated with more and shorter fixations, more saccades and saccades with higher amplitudes as well as heightened stimulus-independent variation of eye vergence. The latter results suggest a coupling of eye behavior to internally generated information and associated cognitive processes, i.e. searching for ideas. Our results support eye behavior patterns as indicators of goal-directed internally focused cognition through mechanisms of attenuation of visual input and coupling of eye behavior to internally generated information.

Background: Camel milk (CM) and Nigella sativa (NS) have been traditionally claimed to cure wide range of diseases and used as medicine in different part of world, particularly in Saudi Arabia. Several research studies have been published that proved beneficial effects of CM and NS. Objective: This study was undertaken to investigate the antihepatotxic potential of CM and NS oil (NSO) against thioacetamide (TAA)-induced hepato and nephrotoxicity in rats. Materials and Methods: Thirty female Albino Wistar rats were randomly divided in to six groups having five rats in each group. A single subcutaneous injection of TAA (100 mg/kg b. w.) was administered to all the rats in Group-II to VI on 1st day to induce hepatorenal damage. Group I served as a normal control while Group II served as toxic control for comparison purpose. Experimental animals in Group III, IV, and V were supplemented with fresh CM, (250 mL/24 h/cage), NSO (2 mL/kg/day p. o.), and NSO + fresh CM, respectively. Group VI was treated with a polyherbal hepatoprotective Unani medicine Jigreen (2 mL/kg/day p. o.) for 21 days. TAA-induced hepatorenal damage and protective effects of CM and NSO were assessed by analyzing liver and kidney function tests in the serum. Histopathology of liver and kidney tissues was also carried out to corroborate the findings of biochemical investigation. Results: The results indicated that the TAA intoxicated rats showed significant increase in the alanine transaminase, aspartate transaminase, gamma-glutamyl transpeptidase, alkaline phosphatase, lipid profile, urea, creatinine, uric acid, sodium, and potassium levels in serum. Treatment of rats with CM, NSO, and CM plus NSO combination and Jigreen significantly reversed the damage and brought down the serum biochemical parameters and lipid profile toward the normal levels. The histopathological studies also support the hepato and nephroprotective effects of CM and NSO. Conclusion: This study demonstrated the ameliorative

Francis Bacon's concept of objectivity and the idols of the mind.

PubMed

Zagorin, P

2001-12-01

This paper examines the concept of objectivity traceable in Francis Bacon's natural philosophy. After some historical background on this concept, it considers the question of whether it is not an anachronism to attribute such a concept to Bacon, since the word 'objectivity' is a later coinage and does not appear anywhere in his writings. The essay gives reasons for answering this question in the negative, and then criticizes the accounts given of Bacon's understanding of objectivity by Lorraine Daston and Julie Robin Solomon. It argues that this understanding is most directly and fully expressed in his discussion of the idols of the mind. In this connection, the paper notes Bacon's critical attitude to sixteenth-century scepticism and its relevance to the idea of objectivity implicit in his comments on the idols. In conclusion, the paper argues that Bacon was not a pure empiricist and describes the place assigned to theories and hypotheses in his natural philosophy.

2012-01-01

While past research has demonstrated that low idea density (ID) scores from natural language samples correlate with late life risk for cognitive decline and Alzheimer’s disease pathology, there are no published rubrics for collecting and analyzing language samples for idea density to verify or extend these findings into new settings. This paper outlines the history of ID research and findings, discusses issues with past rubrics, and then presents an operationalized method for the systematic measurement of ID in language samples, with an extensive manual available as a supplement to this article (Analysis of Idea Density, AID). Finally, reliability statistics for this rubric in the context of dementia research on aging populations and verification that AID can replicate the significant association between ID and late life cognition are presented.

1831: the map that launched the idea of global health.

PubMed

Koch, Tom

2014-08-01

Today we take for granted the idea of global health, of disease as an international event. Increasingly, we assume as well that the international spread of disease can be traced to human travel patterns as well as to recurring environmental conditions. Perversely, the idea of ‘global health’ and its inverse, global disease, owes little to the three-dimensional imaging of the planet and almost everything to the two-dimensional plane of the map. Here the idea of global disease is traced from its beginnings in the 18th century to its 19th-century introduction in maps of the first cholera pandemic. This global perspective, and the responsibilities it promoted among civil officials, can be seen in modern studies of cancer, influenza and other conditions with both environmental foundations and international presence.

Animal models provide a useful platform for developing and testing new drugs to treat liver fibrosis. Accordingly, we developed a novel automated system to evaluate liver fibrosis in rodent models. This system uses second-harmonic generation (SHG)/two-photon excited fluorescence (TPEF) microscopy to assess a total of four mouse and rat models, using chemical treatment with either thioacetamide (TAA) or carbon tetrachloride (CCl 4 ), and a surgical method, bile duct ligation (BDL). The results obtained by the new technique were compared with that using Ishak fibrosis scores and two currently used quantitative methods for determining liver fibrosis: the collagen proportionate area (CPA) and measurement of hydroxyproline (HYP) content. We show that 11 shared morphological parameters faithfully recapitulate Ishak fibrosis scores in the models, with high area under the receiver operating characteristic (ROC) curve (AUC) performance. The AUC values of 11 shared parameters were greater than that of the CPA (TAA: 0.758-0.922 vs 0.752-0.908; BDL: 0.874-0.989 vs 0.678-0.966) in the TAA mice and BDL rat models and similar to that of the CPA in the TAA rat and CCl 4 mouse models. Similarly, based on the trends in these parameters at different time points, 9, 10, 7, and 2 model-specific parameters were selected for the TAA rats, TAA mice, CCl 4 mice, and BDL rats, respectively. These parameters identified differences among the time points in the four models, with high AUC accuracy, and the corresponding AUC values of these parameters were greater compared with those of the CPA in the TAA rat and mouse models (rats: 0.769-0.894 vs 0.64-0.799; mice: 0.87-0.93 vs 0.739-0.836) and similar to those of the CPA in the CCl 4 mouse and BDL rat models. Similarly, the AUC values of 11 shared parameters and model-specific parameters were greater than those of HYP in the TAA rats, TAA mice, and CCl 4 mouse models and were similar to those of HYP in the BDL rat models.

Design by Analogy: Achieving More Patentable Ideas from One Creative Design

NASA Astrophysics Data System (ADS)

Jia, Li-Zhen; Wu, Chun-Long; Zhu, Xue-Hong; Tan, Run-Hua

2018-12-01

A patent is a kind of technical document to protect intellectual property for individuals or enterprises. Patentable idea generation is a crucial step for patent application and analogy is confirmed to be an effective technique to inspire creative ideas. Analogy-based design usually starts from representation of an analogy source and is followed by the retrieval of appropriate analogs, mapping of design knowledge and adaptation of target solution. To diffuse one core idea into other new contexts and achieve more patentable ideas, this paper mainly centered on the first two stages of analogy-based design and proposed a patentable ideation framework. The analogical information of the source system, including source design problems and solution, was mined comprehensively through International Patent Classification analysis and represented in the form of function, behavior and structure. Three heuristics were suggested for searching the set of candidate target systems with a similar design problem, where the source design could be transferred. To systematize the process of source representation, analogs retrieval, idea transfer, and solution generation, an ideation model was put forward. Finally, the bladeless fan was selected as a source design to illustrate the application of this work. The design output shows that the representation and heuristics are beneficial, and this systematic ideation method can help the engineer or designer enhance creativity and discover more patentable opportunities.

2013-11-01

Wild edible plants (WEP), traditionally consumed in the Mediterranean diet, are considered a rich source of natural antioxidants but can also accumulate significant amount of nitrates. Most WEP are cooked before consumption, therefore, a study was conducted to evaluate the effects of boiling, steaming and microwave cooking processes on the total antioxidant activity (TAA) and nitrate content of eight common WEP. Boiling caused the highest losses of TAA, resulting in a reduction of the TAA on dry weight (DW) basis ranging from 5.5% in Beta vulgaris up to 100% in Urtica dioica. Steaming and microwaving produced the highest increase of TAA on DW basis in Helminthotheca echioides (249.7%) and Taraxacum officinale (60.7%). Boiling caused the highest reduction of nitrate content in all species excluding Asparagus acutifolius that maintained almost unvaried its already low nitrate content. These results suggest that cooking has not always negative effect on product quality, since in certain cases, it may even enhance the nutritional value of WEP by increasing their TAA and reducing the nitrate content.

Cathode catalyst for primary phosphoric fuel cells

Walsh, F.

1980-01-01

Alkylation of Vulcan XC-72 provided the most stable bond type for linking CoTAA to the surface of the carbon; this result is based on data obtained by cyclic voltammetry, pulse voltammetry and by release of 14C from bonded CoTAA. Half-cell tests at 100 C in 85% phosphoric acid showed that CoTAA bonded to the surface of carbon (Vulcan XC-72) via an alkylation procedure is a more active catalyst than is platinum based on a factor of two improvement in Tafel slope; dimeric CoTAA has catalytic activity equal to platinum. Half-cell tests also showed that bonded CoTAA catalysts do not suffer a loss in potential when air is used as a fuel rather than oxygen. Commercially available PTFE was shown to be stable for four months in 200 C 85% phosphoric acid based on lack of change in surface wetting properties, IR and physical characteristics. When stressed electrochemically in 150 C 85% phosphoric acid, PTFE also showed no changes after one month.

Forming ideas about health: a qualitative study of Ontario adolescents.

PubMed

Michaelson, Valerie; McKerron, Margaret; Davison, Colleen

2015-01-01

Adolescence is a crucial period of child development during which one's ideas about health are formed. However, little is known about the different contexts, experiences, and potential other factors that contribute to shaping the health ideas of adolescent populations, particularly when they are not seeking out the information for a particular purpose. In this Ontario-based qualitative study, grounded theory methods were used to explore ways that health knowledge is obtained in adolescents (age 10-16). A purposeful, criterion-based sampling strategy was used, and data were collected through seven focus groups (n=40). Findings indicate that while young people get their ideas about health through both didactic and organic learning contexts, the significant impact of organic learning is often overlooked. Categories of organic learning that emerged include self-reflective experience, the experience of close contacts, casually observing others, and common discourse. This study suggests that one central way that young people get their ideas about health is from living life: from the people they watch, the conversations that they have, and the experiences they live. Findings support the development of effective health promotion messages and also contribute to considering the place of some aspects of organic learning in the development of health-related resources that target adolescent populations.

Interaction effect of response medium and working memory capacity on creative idea generation.

PubMed

Hao, Ning; Yuan, Huan; Cheng, Rui; Wang, Qing; Runco, Mark A

2015-01-01

This study aimed to examine the interaction effect of response medium (i.e., write down ideas and orally report ideas) and working memory capacity (WMC) on creative idea generation. Participants (N = 90) with higher or lower WMC were asked to solve Alternative Uses Task (AUT) problems in the condition of writing down or speaking out ideas. The results showed that fluency of AUT performance was higher in the writing than in the speaking condition. Additionally, participants with higher WMC performed better on AUT fluency than those with lower WMC in the writing condition, while they showed no difference in the speaking condition. Moreover, level of cognitive demand fully mediated the effect of response medium on AUT fluency. Theoretically, these findings indicated the importance of WMC in creative idea generation, which supported the controlled-attention theory of creativity. Practical implications and future directions were discussed.

Exploring Persona-Scenarios - Using Storytelling to Create Design Ideas

NASA Astrophysics Data System (ADS)

Madsen, Sabine; Nielsen, Lene

This paper explores the persona-scenario method by investigating how the method can support project participants in generating shared understandings and design ideas. As persona-scenarios are stories we draw on narrative theory to define what a persona-scenario is and which narrative elements it should consist of. Based on an empirical study a key finding is that despite our inherent human ability to construct, tell, and interpret stories it is not easy to write and present a good, coherent, and design-oriented story without methodical support. The paper therefore contributes with guidelines that delineate a) what a design-oriented persona-scenario should consist of (product) and b) how to write it (procedure) in order to generate and validate as many, new, and shared understandings and design ideas as possible (purpose). The purpose of the guidelines is to facilitate the construction of persona-scenarios as good, coherent stories, which make sense to the storytellers and to the audience - and which therefore generate many, new, and shared understandings and design ideas.

Diagramming Scientific Papers - A New Idea for Understanding/Teaching/Sharing Science

NASA Astrophysics Data System (ADS)

Saltus, R. W.; Fedi, M.

2014-12-01

How do we best communicate scientific results? As the number of scientists and scientific papers steadily increases, one of the greatest challenges is effective and efficient sharing of science. The official repository of scientific knowledge is the peer-reviewed journal archive. However, this primary knowledge can be difficult to access and understand by anyone but a relevant specialist. We propose some new ideas for diagramming the content and significance of scientific papers using a simple and intuitive graphical approach. We propose a visual mapping that highlights four fundamental aspects of most scientific papers: Data, Methods/Models, Results/Ideas, and Implications/Importance. Each of these aspects is illustrated within boxed fields which contain one or more labeled elements positioned to reflect novelty (aka originality) and impact relative to the vertical and horizontal axes. The relative position of the boxed fields themselves indicates the relative significance of data, methods, ideas, or implications to the paper. Optional lines between boxed elements indicate the flow and dependence of data/methods/ideas within the paper. As with any graphical depiction, you need to see it to best appreciate it -- this written abstract is only meant as an introduction to the idea.We anticipate that diagramming may prove useful in both communication of scientific ideas among scientists as well as in education and outreach. For example, professors could assign diagramming of papers as a way to help students organize their thoughts about the structure and impact of scientific articles. Students could compare and defend their diagrams as a way to facilitate discussion/debate. Authors could diagram their own work as a way to efficiently summarize the importance and significance of their work. We also imagine that (in the future) automatic diagramming might be used to help summarize or facilitate the discovery of archived work.

US Cosmic Visions: New Ideas in Dark Matter 2017 : Community Report

Feng, J.; Fox, P.; Dawson, W. A.

This white paper summarizes the workshop “U.S. Cosmic Visions: New Ideas in Dark Matter” held at University of Maryland from March 23-25. The flagships of the US Dark Matter search program are the G2 experiments ADMX, LZ, and SuperCDMS, which will cover well-motivated axion and WIMP dark matter over a range of masses. The workshop assumes that a complete exploration of this parameter space remains the highest priority of the dark matter community, and focuses instead on the science case for additional new small-scale projects in dark matter science that complement the G2 program (and other ongoing projects worldwide). Itmore » therefore concentrates on exploring distinct, well-motivated parameter space that will not be covered by the existing program; on surveying ideas for such projects (i.e. projects costing ~$10M or less); and on placing these ideas in a global context. The workshop included over 100 presentations of new ideas, proposals and recent science and R&D results from the US and international scientific community.« less

This study analyzed trends in large total joint arthroplasties (TJA) and in the proportion of these procedures performed on patients with rheumatoid arthritis (RA). The US Nationwide Inpatient Sample (2002-2012) was used to identify the incidences of total shoulder (TSA), elbow (TEA), knee (TKA), hip (THA), and ankle (TAA) arthroplasty and the proportion of these performed with coexisting RA. The prevalence of RA among patients with TJA increased 3.0%. The prevalence of RA among cases of TEA and TSA decreased by 50% (p < 0.0001) and 18% (p = 0.0016), respectively; a 38.0% decrease occurred in the prevalence of RA among TAA (p = 0.06); and nonsignificant increases were seen among THA and TKA. The average age difference between RA and non-RA patients undergoing TJA narrowed by 2 years (p < 0.0001). There was a greater reduction in the proportion of TSA, TEA, and TAA groups among women with RA than men with RA. In the TSA and TEA groups, there was a reduction in the proportion of whites with RA, but not blacks. The proportion of privately insured TSA and TAA patients with RA decreased, while patients with RA undergoing TSA, TEA, or TAA who were receiving Medicaid (government medical insurance) remained relatively stable over time. The prevalence of RA has decreased among TSA and TEA patients. A nonsignificant decline occurred among TAA patients. The average age of TJA patients with RA is beginning to mirror those without RA. Sex ratios for TSA, TEA, and TAA patients are following a similar pattern. These results may be evidence of the success of modern RA treatment strategies.

Hepatoprotective effects of naturally fermented noni juice against thioacetamide-induced liver fibrosis in rats.

Excessive reactive oxygen species (ROS) can result in inflammation and cytokine secretion in the liver, and then activate hepatic stellate cells that cause the accumulation of extracellular matrix proteins, especially collagen, in liver tissue. Naturally fermented noni juice (NJ; Morinda citrifolia) has been used for decades as a nutraceutical in humans. In this study, we intended to examine if NJ can ameliorate ROS-induced liver fibrosis via a thioacetamide (TAA)-induced rat model. The 50 rats used in this study were separated into five groups of 10 rats each for 8 weeks as follows: (1) control group; (2) TAA; (3) TAA+low-dose NJ (2.51 mL NJ/kg); (4) TAA+medium-dose NJ (5.02 mL NJ/kg); and (5) TAA+high-dose NJ (7.52 mL NJ/kg). Treatment with TAA resulted in lower body weight and serum lipid levels (p<0.05), while liver weight and collagen contents, and serum alanine aminotransferase and aspartate aminotransferase values were increased (p<0.05). The protective effects of NJ on TAA treatment resulted from decreased endoplasmic reticulum stress-related gene expressions (p<0.05), inflammatory cytokines, collagen accumulation, and matrix metalloproteinase (MMP-2 and MMP-9) activities, as well as upregulated (p<0.05) tissue inhibitors of metalloproteinase (TIMP-1 and TIMP-3) in livers. NJ also increased hepatic antioxidant capacities (p<0.05). Naturally fermented NJ manifests a protective potential on liver fibrosis via the enhancement of antioxidant capacities, as well as decreasing endoplasmic-reticulum stress and MMP-2/MMP-9 activities.

It has been reported previously that the density of angiotensin II receptors is increased in the rat liver in experimentally-induced fibrosis. We hypothesized that pharmacological blockade of angiotensin receptors may produce beneficial effects in models of liver fibrosis. In this study, we used the widely used thioacetamide (TAA)-induced model of liver fibrosis (300 mg/L TAA ad libitum for 12 weeks). Rats received daily injections (i.p), lasting 4 weeks of the angiotensin II type 1 receptor antagonists, losartan 30 mg/kg (TAA + L) or telmisartan 10 mg/kg (TAA + T) and were compared to rat that received TAA alone. Chronic treatment with losartan and telmisartan was associated with a significant reduction in the activity of alkaline phosphatase, and decreased concentrations of tumor necrosis factor-alpha and transforming growth factor beta-1 compared to controls. We also found a significant reduction interleukin-6 in rats receiving telmisartan (P < 0.05) but not losartan. Both treatments increased the concentration of liver glutathione along with a concomitant decrease of GSSG compared to controls. In addition, increased paraoxonase 1 activity was observed in the serum of rats receiving telmisartan group compared to the TAA alone controls. Finally, histological evaluation of liver sections revealed losartan and telmisartan treatment was associated with reduced inflammation and liver fibrosis. Taken together, these results indicate that both telmisartan and losartan have anti-inflammatory and anti-oxidative properties in the TAA model of liver fibrosis. These finding add support to a growing body of literature indicating a potentially important role for the angiotensin system in liver fibrosis and indicate angiotensin antagonists may be useful agents for fibrosis treatment.

The impact of parent advocacy groups, the Internet, and social networking on rare diseases: the IDEA League and IDEA League United Kingdom example.

The development of the Internet and subsequent evolution of social networking has significantly changed the effectiveness of patient advocacy groups for rare diseases. The greatest degree of change has occurred at the patient level, with an increased ability of affected individuals to share experiences and support, and to raise public awareness. Other changes have occurred, not only in the way rare diseases are diagnosed, studied, and treated, but also in how they are addressed at the level of legislation and public policy. The International Dravet syndrome Epilepsy Action League (IDEA League) is the leading patient advocacy organization for Dravet syndrome and related genetic ion-channel epilepsy disorders (hereafter referred to as Dravet syndrome or severe myoclonic epilepsy of infancy, SMEI). The IDEA League's mission encompasses international support and outreach for patients and families, as well as collaboration with physicians, medical education, health care coordination, and research. The IDEA League is an excellent example of the impact of patient advocacy groups, the Internet, and social networking on the landscape of rare diseases.

Intracranial aneurysms (IAs), abdominal aortic aneurysms (AAAs), and thoracic aortic aneurysms (TAAs) all have a familial predisposition. Given that aneurysm types are known to co-occur, we hypothesized that there may be shared genetic risk factors for IAs, AAAs, and TAAs. We performed a mega-analysis of 1000 Genomes Project-imputed genome-wide association study (GWAS) data of 4 previously published aneurysm cohorts: 2 IA cohorts (in total 1516 cases, 4305 controls), 1 AAA cohort (818 cases, 3004 controls), and 1 TAA cohort (760 cases, 2212 controls), and observed associations of 4 known IA, AAA, and/or TAA risk loci (9p21, 18q11, 15q21, and 2q33) with consistent effect directions in all 4 cohorts. We calculated polygenic scores based on IA-, AAA-, and TAA-associated SNPs and tested these scores for association to case-control status in the other aneurysm cohorts; this revealed no shared polygenic effects. Similarly, linkage disequilibrium-score regression analyses did not show significant correlations between any pair of aneurysm subtypes. Last, we evaluated the evidence for 14 previously published aneurysm risk single-nucleotide polymorphisms through collaboration in extended aneurysm cohorts, with a total of 6548 cases and 16 843 controls (IA) and 4391 cases and 37 904 controls (AAA), and found nominally significant associations for IA risk locus 18q11 near RBBP8 to AAA (odds ratio [OR]=1.11; P=4.1×10(-5)) and for TAA risk locus 15q21 near FBN1 to AAA (OR=1.07; P=1.1×10(-3)). Although there was no evidence for polygenic overlap between IAs, AAAs, and TAAs, we found nominally significant effects of two established risk loci for IAs and TAAs in AAAs. These two loci will require further replication. © 2016 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

Liver cirrhosis is characterized by portal hypertension. However, the alteration of portal hypertension-related derangements during cirrhosis resolution is not well known. The present study aimed to establish animal models with cirrhosis resolution and to investigate the relevant changes during this process. Male Sprague-Dawley rats were applied. In reverse thioacetamide (rTAA) model, rats were randomly allocated into four groups with control, thioacetamide (TAA) cirrhosis and rTAA groups that discontinued TAA for 4 or 8 weeks after cirrhosis induction. In reverse bile duct ligation (rBDL) model, rats received choledochoduodenal shunt surgery upon the establishment of cirrhosis and 4, 8, or 16 weeks were allowed after the surgery. At the end, portal hypertension-related parameters were evaluated. Cirrhosis resolution was observed in rTAA groups. Portal pressure (PP) decreased after cirrhosis resolution but remained higher than control group (control, TAA, rTAA4, rTAA8 (mmHg): 5.4 ± 0.3, 12.9 ± 0.3, 8.6 ± 0.4, 7.6 ± 0.6). Further survey found the increased splanchnic blood flow did not reduce during cirrhosis resolution. The extrahepatic pathological angiogenesis was not ameliorated (% of mesenteric window area: 1.2 ± 0.3, 7.3 ± 1.1, 8.3 ± 1.0, 11.3 ± 2.7). In collateral system, the shunting degree reduced while the vessels structure remained. The vascular contractility of all systems and nitric oxide (NO) production were normalized. In rBDL series, PP decreased in rBDL16 groups but the extrahepatic angiogenesis persisted. In conclusion, cirrhosis resolution attenuates but not completely normalizes portal hypertension because of persistently high splanchnic inflow and angiogenesis. In clinical setting, vascular complications such as varices could persist after cirrhosis resolution and further investigation to define the follow-up and treatment strategies is anticipated. © 2018 The Author(s).

Assiduous String-Savers: The Idea-Generating Strategies of Professional Expository Writers.

ERIC Educational Resources Information Center

Root, Robert L., Jr.

A study was conducted over a two-year period to investigate the idea-generating strategies of six professional writers and their implications for students. Because finding an idea that leads to a journal or newspaper column is so important to a writer, an attempt was made to learn ways professional writers establish working plans and develop a…

This article explores the expansion of feminist ideas as both a conceptual and a political issue. It focuses on two major theories of social change, world culture theory (WCT) and world system analysis (WSA), comparing and contrasting how they frame gender as a factor shaping society, how they account for the diffusion of feminist ideas and how…

Preservice elementary teachers' development of PCK-readiness about learners' science ideas

Smithey, Julie Faye

Preservice elementary teachers face many daunting challenges as they learn to teach science. Teacher educators try to design methods courses that help them meet these challenges and prepare them for the experiences they will have as student teachers and new teachers. Because they often do not spend much time with students, it is a general assumption that preservice teachers are unable to develop pedagogical content knowledge (PCK) with respect to their learners. Rather than focus on what they are unable to do, however, this dissertation explores how a methods course might foster consideration of learners' science ideas, an important component of PCK. Perhaps preservice teachers can learn to develop PCK-readiness, thus putting them in a good position to develop rich usable PCK once they have more experience in the classroom. This study follows a class of preservice teachers through an elementary science methods course. It describes the trajectories of eight focus preservice teachers' thinking about their learners. It also explores how the entire class made sense of a set of activities designed to foster consideration of learners' ideas. Results indicate that with scaffolds, preservice teachers are able to think in complex ways about their learners' ideas, including considering how to use those ideas in instruction. The trajectories of the preservice teachers varied but generally showed growth in thinking about learners' ideas, although some were focused on or influenced by particular aspects while others made more consistent growth in several areas. Generally, the course activities supported thinking about how to deal with learners' ideas but not the characteristics of those ideas. This study contributes to the field by providing a description of how a range of preservice teachers engaged with the activities in the methods course. In addition, it describes the kind of influence that a methods course might have on preservice teachers' development of a crucial aspect

Experiments on sparsity assisted phase retrieval of phase objects

Iterative phase retrieval algorithms such as the Gerchberg-Saxton method and the Fienup hybrid input-output method are known to suffer from the twin image stagnation problem, particularly when the solution to be recovered is complex valued and has centrosymmetric support. Recently we showed that the twin image stagnation problem can be addressed using image sparsity ideas (Gaur et al 2015 J. Opt. Soc. Am. A 32 1922). In this work we test this sparsity assisted phase retrieval method with experimental single shot Fourier transform intensity data frames corresponding to phase objects displayed on a spatial light modulator. The standard iterative phase retrieval algorithms are combined with an image sparsity based penalty in an adaptive manner. Illustrations for both binary and continuous phase objects are provided. It is observed that image sparsity constraint has an important role to play in obtaining meaningful phase recovery without encountering the well-known stagnation problems. The results are valuable for enabling single shot coherent diffraction imaging of phase objects for applications involving illumination wavelengths over a wide range of electromagnetic spectrum.

In honor of the 250th anniversary of Euler's discovery of three libration points in Russia in 1767 in the area of two rotating gravitational attractors in 2017 an International Interdisciplinary Conference “Euler Readings MRSU 2017” was held in Moscow Region State University (MRSU). The Conference demonstrated that the Euler's ideas continue to remain relevant at the present time. This paper summarizes the main achievements on the basis of Leonard Euler's ideas presented at the Conference.

A few of our favorite unconfirmed ideas

PubMed Central

2015-01-01

Medical practice is rooted in our dependence on the best available evidence from incremental scientific experimentation and rigorous clinical trials. Progress toward determining the true worth of ongoing practice or suggested innovations can be glacially slow when we insist on following the stepwise scientific pathway, and a prevailing but imperfect paradigm often proves difficult to challenge. Yet most experienced clinicians and clinical scientists harbor strong thoughts about how care could or should be improved, even if the existing evidence base is thin or lacking. One of our Future of Critical Care Medicine conference sessions encouraged sharing of novel ideas, each presented with what the speaker considers a defensible rationale. Our intent was to stimulate insightful thinking and free interchange, and perhaps to point in new directions toward lines of innovative theory and improved care of the critically ill. In what follows, a brief background outlines the rationale for each novel and deliberately provocative unconfirmed idea endorsed by the presenter. PMID:26728101

Early object relations into new objects.

. Pain deprived of meaning is buried as neurosis. As we see in John's story, experience that cannot be integrated at the time is locked away from whatever developmental progression has occurred. Intolerable affects and ideas require particular circumstances of object relation and verbalization such as are found in the context of psychoanalysis and arrived at through psychoanalytic interpretation. Or, as in John's case, they may give way only slowly and irregularly over long stretches of time, when subjected to life experiences in the company of new object relations. Broadly stated, the Freud-Dann paper helps us to appreciate that there are several pathways of protection and growth in the ego that involve the discovery or construction of new objects. Family-romance fantasies are a common manifestation of new-object phenomena. Transitional object phenomena are also related. For some individuals at a particular time or over a span of time, providing the right circumstances for the resumption of maturational and developmental growth is all it takes to make them whole. Changes in the adaptive ego are sufficient to alleviate the conflicts stemming from the neurotic ego. For others, depending upon the degree of their neurotic impairment, or for the same individual under other circumstances, therapeutic change in the deepest sense demands the relatively unconditional presence of the interactive and interpreting other. Children of the storm who come in for shelter and warmth may thrive, but they also require a means of getting at the storm in their core that has been internalized as part of the ego's survival mechanism. What can be extracted from the poignant story of the Bulldogs Bank children about current child-analytic technique? The psychoanalytic piano now may be more formally conceptualized as having white as well as black keys. Most analyses, adult and child, have been conducted as though the "black keys"--pressure to mastery through repetition and its subsequent
