Full Text Available The last fifteen years have seen the development of a lively interest, on an international scale, in the topic of emotion in music, documented by numerous noteworthy publications: the two volumes edited by Juslin and Sloboda [2001; 2010], the monographic issues of the journal «Musicae Scientiae» published in 2001 and 2011, and many other texts published in various parts of the world. The topic is not without repercussions also for those involved in musical analysis; and it is no mere chance that the English journal «Music Analysis» chose to dedicate the volume we are now reviewing to the subject. The contributions contained in the volume derive from an international meeting held in Durham in September 2009 and offer a fairly lively cross-section of a wide series of questions. Our only regret is that with the exception of three nordic names (Juslin, Lindström and Eerola, whose place is now solidly established in English language publications all the authors come from the now almost self-referential context of British or American research. But of course this is nothing new.

Soviet books and publications on hydrology (continental) and hydrogeology: titles and some notes on obtaining Soviet monographs

Science.gov (United States)

Manheim, Frank T.

1966-01-01

A common method of publication for Soviet scientists, which partly supplants periodicals, is the publication of a collection of articles on a general area of research, frequently by members of a given institution. An extensive sampling of world geologic literature for 1961 (Hawkes, 1966) showed that 33 percent of Soviet titles appeared in periodicals whereas 55 percent of North American and 70 percent of Western European literature appeared in this form. The Soviet predilection for symposia and collections of papers makes searching for information on a given subject more difficult for Westerners because the monographs in question are often not included in exchange agreements (except informal personal ones) with Western libraries and institutions, because they may be primed in small editions, and because such publications frequently escape the notice of Western abstract journals. Unless one is fortunate enough to have many personal contacts in the Soviet Union, there seems to be little alternative to at least a rudimentary knowledge of Russian in order to stay abreast of work published as monographs and in collections.

Bibliometric analysis of martial arts monographs published in Spain (1906-2006

Directory of Open Access Journals (Sweden)

Mikel Pérez Gutiérrez

2012-07-01

Full Text Available This paper examines the martial arts monographs published in Spain between 1906 and 2006 from a bibliometric point of view. Starting from Pérez and Gutiérrez’s previous bibliography (2008, the total number of published monographs following the criteria of subject, decade and the combination of both was analyzed. The results showed a total of 2.036 books (1.285 original editions with a prevalence of Japanese and Chinese martial arts. A group of eight subjects exceeded a hundred volumes (karate, judo/jujutsu, taijiquan, wu-shu/kung fu, classics, qigong, philosophy, history and education, and aikido, with two patterns of bibliographic evolution appearing. The first, represented by Japanese martial arts considered as a group and martial arts focused on the utilitarian and/or sporting performance aspects (judo/jujutsu, karate and wu-shu/kung fu, developed increasingly until the 80’s when it followed a steady-state and/or drop. The second model, which characterises the Chinese martial arts group and martial arts mainly focused on healthy and/or spiritual aspects of training (taijiquan, qigong, aikido, has increased significantly from the 90’s until the present moment. The interpretation of these patterns and the evolution of the martial arts bibliographic production in Spain highlights some aspects such as the development of the Spanish society and sports practice, bibliographic production, reading habits, or the cultural influences of eastern countries on Spain.

This study compares the accuracy of cardiovascular screening in active adolescents and young adults using a standardised history, physical examination and resting 12-lead ECG. Participants were prospectively screened using a standardised questionnaire based on the Pre-participation Physical Evaluation Monograph 4th Edition (PPE-4), physical examination and ECG interpreted using modern standards. Participants with abnormal findings had focused echocardiography and further evaluation. Primary outcomes included disorders associated with sudden cardiac arrest (SCA). From September 2010 to July 2011, 1339 participants underwent screening: age 13-24 (mean 16) years, 49% male, 68% Caucasian, 17% African-American and 1071 (80%) participating in organised sports. Abnormal history responses were reported on 916 (68%) questionnaires. After physician review, 495/916 (54%) participants with positive questionnaires were thought to have non-cardiac symptoms and/or a benign family history and did not warrant additional evaluation. Physical examination was abnormal in 124 (9.3%) participants, and 72 (5.4%) had ECG abnormalities. Echocardiograms were performed in 586 (44%) participants for abnormal history (31%), physical examination (8%) or ECG (5%). Five participants (0.4%) were identified with a disorder associated with SCA, all with ECG-detected Wolff-Parkinson-White. The false-positive rates for history, physical examination and ECG were 31.3%, 9.3% and 5%, respectively. A standardised history and physical examination using the PPE-4 yields a high false-positive rate in a young active population with limited sensitivity to identify those at risk for SCA. ECG screening has a low false-positive rate using modern interpretation standards and improves detection of primary electrical disease at risk of SCA. Published by the BMJ Publishing Group Limited.

The vital few meet the trivial many: unexpected use patterns in a monographs collection.

Science.gov (United States)

Eldredge, J D

1998-01-01

PURPOSE: To test three related hypotheses about monographs circulation at academic health sciences libraries: (1) Juran's "Vital Few" Principle, sometimes incorrectly referred to as the "Pareto Principle"; (2) most (> 30%) new monographs will not circulate within four years; and, (3) Trueswell's 20/80 rule concerning intensity of monographs circulation. METHODS: Retrospective circulation study conducted at a major academic health sciences library in November 1997 on monographs acquired during 1993, utilizing an online review file. RESULTS: Unexpectedly, most monographs (84%) had circulated at least once in the four years following acquisition. Combining circulation and in-house data revealed that 90.7% of the monographs acquired in 1993 had been used at least once. Small percentages of these monographs produced disproportionately high circulation levels. CONCLUSION: Monographs circulation rates confirm Juran's Vital Few principle. Most monographs circulated at least once in contrast to results reported by the Pittsburgh Study or other studies reported by Hardesty and Fenske. The results do not comply with Trueswell's 20/80 ratio rule. Further research needs to investigate the effects of low students to books ratios and problem-based learning (PBL) curricula upon monographs utilization. PMID:9803291

The Windscale Inquiry: the public inquiry system on trial

International Nuclear Information System (INIS)

Garry, A.M.

1992-01-01

This thesis is concerned with the Windscale Inquiry of 1977 and its effect on the public inquiry system. It focusses both on the major influences of the Windscale Inquiry process, and on the participants, their aims, motivations, expectations and achievements. It provides the most detailed examination of the Inquiry to date and, as a result, uncovers aspects of the process while have not been explored previously. The central questions of the thesis are: Was the outcome of the Windscale Inquiry inevitable or could it have reached different conclusions? and did the Windscale Inquiry demonstrate that the public inquiry system could be used by a government to reach a decision which it favoured? The thesis argues that the outcome of the Windscale Inquiry was almost inevitable. In fact it was found that the Inspector had made up his mind in favour of oxide reprocessing before the Inquiry opened. However, this finding does not express fully the Inquiry's impact, because, as the thesis shows, the Inquiry became a mechanism which forced the nuclear industry and the government to explain, and substantially alter, some parts of their policies. The process of bringing the government and industry to account, did not alter the THORP decision, but it demonstrated that any subsequent inquiries could subject nuclear developments to searching criticism and investigation. Indeed it is suggested that the Windscale Inquiry made it impossible for subsequent Governments to proceed with nuclear expansion without subjecting them to the public inquiry process. Part I of the thesis examines the history and structure of the public Inquiry system and the relevant aspects of planning law. Part II describes the history of reprocessing and the themes which led to the public inquiry being established. Part III forms the most detailed part of the thesis and examines the Windscale Inquiry process focussing on the participants and the issues involved. (author)

Could EU herbal monographs contribute to Malta's treatment armamentarium?

Science.gov (United States)

Micallef, B; Attard, E; Serracino-Inglott, A; Borg, J J

2015-03-15

Ten years have passed since Directive 2004/24/EC regulating herbal medicinal products across the EU were published. The directive created the Committee on Herbal Medicinal Products within the European Medicines Agency whose remit includes the creation and publishing of official EU monographs on herbal medicinal products. These monographs include the official uses of the products and their evidence for efficacy and safety. To this effect, we are interested in analysing the potential impact herbal product EU monographs could have on the therapeutic treatment options available for prescribers in Malta. Therefore our aim was two-fold. First, to rationalise the spread of indications of the herbal substances listed in the community herbal monograph inventory and subsequently determine if these herbal substances could potentially contribute to the treatment options available in our local scenario (Malta). 128 EU monographs were analysed resulting in a total of 230 indications which subsequently codified into 42 unique ATC codes. The Malta Medicines List contains 1456 unique ATC codes. Comparative analysis of the Malta Medicines List revealed that the 21 therapeutic areas had 4 or less pharmaceutically used substances (5th level ATC codes) registered and therefore in our opinion are areas with limited therapeutic choice. The following 4 therapeutic areas, A05 bile and liver therapy, A13 tonics, A15 appetite stimulants and D03 preparations for treatment of wounds and ulcers, could potentially benefit from the registration of herbal medicinal products according to the EU herbal monographs. If such registration is effected the aforementioned areas would no longer be considered limited because more than 4 therapeutic choices would be available to prescribers. This study is the first study across the EU to analyse the potential impact of published EU herbal monographs on therapeutic coverage in an EU member state and confirms the notion that herbal products could potentially

Probabilistic safety assessment of nuclear power plants: a monograph

International Nuclear Information System (INIS)

Solanki, R.B.; Prasad, Mahendra

2007-11-01

This monograph on probabilistic safety assessment (PSA) is addressed to the wide community of professionals engaged in the nuclear industry and concerned with the safety issues of nuclear power plants (NPPs). While the monograph describes PSA of NPPs, the principles described in this monograph can be extended to other facilities like spent fuel storage, fuel reprocessing plants and non-nuclear facilities like chemical plants, refineries etc. as applicable. The methodology for risk assessment in chemical plants or refineries is generally known as quantitative risk analysis (QRA). The fundamental difference between NPP and chemical plant is that in NPPs the hazardous material (fuel and fission products) are contained at a single location (i.e. inside containment), whereas in a chemical plant and reprocessing plants, the hazardous material is present simultaneously at many places, like pipelines, reaction towers, storage tanks, etc. Also unlike PSA, QRA does not deal with levels; it uses an integrated approach combining all the levels. The monograph covers the areas of broad interest in the field of PSA such as historical perspective, fundamentals of PSA, strengths and weaknesses of PSA, applications of PSA, role of PSA in the regulatory decision making and issues for advancement of PSA

Traditional uses of American plant species from the 1st edition of Brazilian Official Pharmacopoeia

Directory of Open Access Journals (Sweden)

Maria G. L. Brandão

Full Text Available The first edition of the Brazilian Official Pharmacopoeia (FBRAS, published in 1929, is a rich source of information about American medicinal plants, since it lists species used in both traditional and conventional medicine. In this study, we have performed a survey of the traditional uses of plants described in eighty-seven Monographs from the FBRAS in twenty bibliographies written from the 19th century to the 1970s. Eighty-six different traditional uses are described in three or more books; some of them were cited in ten or more books, illustrating their widespread use and importance in medicine. The species from the first edition of the FBRAS have a long tradition of medical utility, which is confirmed by historical records. In surveying these medically relevant species, we hope to encourage policy makers and the scientific public as a whole to engage in a strong debate in an attempt to improve and facilitate the pharmacological study of these species.

Systematic organization of medicinal plant information: a monograph template proposal

Directory of Open Access Journals (Sweden)

Ana C.B. Carvalho

Full Text Available The use of medicinal plants in Brazil is widespread and is supported by public policies; it has the objective of providing the population with safe and effective herbal medicines of adequate quality. An action in these policies is to develop medicinal plant monographs to gather published information and decide which medicinal plants should be financed by the Brazilian government and distributed by the public health system. Currently, the monographs published worldwide do not present unified information regarding medicinal plants, and generally, they do not cover enough requirements for herbal medicine registration. The aim of this study is to develop a monograph model with standardized information not only about botany, agronomy, quality control, safety, and efficacy but also about relating regulatory aspects that support herbal medicine regulation. The development of standardized monographs favors the fast authorization and distribution of herbal medicines in the public system. The model also points out the lacking studies that should be carried out to supplement the necessary regulatory information of medicinal plants.

The Pharmacokinetics of Second-Generation Long-Acting Injectable Antipsychotics: Limitations of Monograph Values.

Science.gov (United States)

Lee, Lik Hang N; Choi, Charles; Collier, Abby C; Barr, Alasdair M; Honer, William G; Procyshyn, Ric M

2015-12-01

Product monographs (also known by terms such as Summary of Product Characteristics and Highlights of Prescribing Information, depending on the jurisdiction) provide essential information to ensure the safe and effective use of a drug. Medical practitioners often rely on these monographs for guidance on matters related to pharmacokinetics as well as indications, contraindications, clinical pharmacology, and adverse reactions. The clinical and scientific information found within these documents, forming the basis for decision making, are presumed to be derived from well-designed studies. The objective of this review is to examine the source and validity of the pharmacokinetic data used in establishing the half-lives and times to steady-state reported in the product monographs of second-generation long-acting injectable antipsychotics. Thus, we have critically evaluated the clinical trials from which the pharmacokinetic parameters listed in the product monographs were determined. In many cases, the pharmacokinetic information presented in product monographs is of limited use to clinicians wishing to optimize the effectiveness and tolerability of second-generation long-acting injectable antipsychotics. Under such circumstances, off-label prescribing practices may actually produce better clinical outcomes than if decisions were made based on the product monographs alone.

Elaborating European Pharmacopoeia monographs for biotherapeutic proteins using substances from a single source.

Science.gov (United States)

Buda, M; Wicks, S; Charton, E

2016-01-01

For more than twenty years, the European Pharmacopoeia (Ph. Eur.) monographs for biotherapeutic proteins have been elaborated using the multisource approach (Procedure 1), which has led to robust quality standards for many of the first-generation biotherapeutics. In 2008, the Ph. Eur. opened up the way towards an alternative mechanism for the elaboration of monographs (Procedure 4-BIO pilot phase), which is applied to substances still under patent protection, based on a close collaboration with the Innovator company, to ensure a harmonised global standard and strengthen the quality of the upcoming products. This article describes the lessons learned during the P4-BIO pilot phase and addresses the current thinking on monograph elaboration in the field of biotherapeutics. Case studies are described to illustrate the standardisation challenges associated with the complexity of biotherapeutics and of analytical procedures, as well as the approaches that help ensure expectations are met when setting monograph specifications and allow for compatibility with the development of biosimilars. Emphasis is put on monograph flexibility, notably by including tests that measure process-dependent microheterogeneity (e.g. glycosylation) in the Production section of the monograph. The European Pharmacopoeia successfully concluded the pilot phase of the P4-BIO during its 156 th session on 22-23 November 2016.

Monograph of Keçiören Municipality

Directory of Open Access Journals (Sweden)

Savaş Zafer Şahin

2015-12-01

Full Text Available In Turkey, urban administration can be defined from a judicial perspective as the bundle of powers vested in municipalities. It is known that throughout republican history, municipalities, using these powers, have differentiated themselves via their own internal dynamics in parallel to the evolution of public policy and changes in legislation. Yet, it is obvious that there are important gaps in understanding this differentiation taking into consideration the structural conditions of individual municipalities. In particular, in order to thoroughly understand municipalities, it is important to consider periodical pictures of how each municipality has been affected by waves of decentralization and centralization experienced over the last thirty years. In this respect, this monograph, using the same monographic approach developed for the Çankaya Municipality, provides a picture of the existing situation of Ankara’s Keçiören Municipality and presents related problems and potential. This monograph, based on qualitative and quantitative research, presents a holistic evaluation of Keçiören Municipality in terms of its external environment, provision of services, decision-making processes, use of technology and communications.

Use of High Throughput Screening Data in IARC Monograph ...

Science.gov (United States)

Purpose: Evaluation of carcinogenic mechanisms serves a critical role in IARC monograph evaluations, and can lead to “upgrade” or “downgrade” of the carcinogenicity conclusions based on human and animal evidence alone. Three recent IARC monograph Working Groups (110, 112, and 113) pioneered analysis of high throughput in vitro screening data from the U.S. Environmental Protection Agency’s ToxCast program in evaluations of carcinogenic mechanisms. Methods: For monograph 110, ToxCast assay data across multiple nuclear receptors were used to test the hypothesis that PFOA acts exclusively through the PPAR family of receptors, with activity profiles compared to several prototypical nuclear receptor-activating compounds. For monographs 112 and 113, ToxCast assays were systematically evaluated and used as an additional data stream in the overall evaluation of the mechanistic evidence. Specifically, ToxCast assays were mapped to 10 “key characteristics of carcinogens” recently identified by an IARC expert group, and chemicals’ bioactivity profiles were evaluated both in absolute terms (number of relevant assays positive for bioactivity) and relative terms (ranking with respect to other compounds evaluated by IARC, using the ToxPi methodology). Results: PFOA activates multiple nuclear receptors in addition to the PPAR family in the ToxCast assays. ToxCast assays offered substantial coverage for 5 of the 10 “key characteristics,” with the greates

A collaborative narrative inquiry: Two teacher educators learning about narrative inquiry

Directory of Open Access Journals (Sweden)

Barkhuizen, Gary

2009-12-01

Full Text Available With its capacity to unharness the power of narrative to promote meaning-making of lived experience, narrative inquiry is developing as a credible approach to research in several areas in the field of language teaching (Johnson, 2006. This article tells the story of two narrative researchers working in language teacher education who engaged in a collaborative narrative inquiry as both participants and inquirers, in order to learn more about narrative inquiry. The ‘bounded’ nature of their inquiry design provided a feasible way for them to explore their focus of research (i.e. their learning about narrative inquiry, and led them, through an iterative and reflexive process of analysing their narrative data, to formulate what they believe are essential ingredients of principled narrative inquiry work. Four narrative inquiry variables became the scaffolding which enabled them to answer their research questions, and are offered here as a heuristic for teaching practitioners, whether they be teachers, teacher educators or researchers, to guide them in narrative inquiries into their own work.

A Comprehensive List of Items to be Included on a Pediatric Drug Monograph.

Kelly, Lauren E; Ito, Shinya; Woods, David; Nunn, Anthony J; Taketomo, Carol; de Hoog, Matthijs; Offringa, Martin

2017-01-01

Children require special considerations for drug prescribing. Drug information summarized in a formulary containing drug monographs is essential for safe and effective prescribing. Currently, little is known about the information needs of those who prescribe and administer medicines to children. Our primary objective was to identify a list of important and relevant items to be included in a pediatric drug monograph. Following the establishment of an expert steering committee and an environmental scan of adult and pediatric formulary monograph items, 46 participants from 25 countries were invited to complete a 2-round Delphi survey. Questions regarding source of prescribing information and importance of items were recorded. An international consensus meeting to vote on and finalize the items list with the steering committee followed. Pediatric formularies are most commonly the first resource consulted for information on medication used in children by 31 Delphi participants. After the Delphi rounds, 116 items were identified to be included in a comprehensive pediatric drug monograph, including general information, adverse drug reactions, dosages, precautions, drug-drug interactions, formulation, and drug properties. Health care providers identified 116 monograph items as important for prescribing medicines for children by an international consensus-based process. This information will assist in setting standards for the creation of new pediatric drug monographs for international application and for those involved in pediatric formulary development.

Monograph gender in academic writing context

Directory of Open Access Journals (Sweden)

Clara Regina Rodrigues de Souza

2017-08-01

Full Text Available The monograph genre is a social action which organizes the academic culture at the conclusion stage of a Graduation and a Specialization university course, as well as it is a textual action laid out in written production. For this article, we select six copies of this genre, from Letters and Social Sciences courses, through a multiple case study, with a descriptive-interpretativist methodology, to analyze this genre and its recurring movements in your introduction section. Supported by sociorhetorical approaches, as Swales (1990; 2004 and Bhatia (2004; 2009, we investigate monographs in continuous with other initiation genres in the scientific domain. We  conclude that they reveal a prototypicality marked by more general movements, as identifying theme, object presentation, question and research objectives. In addition, for more specific movements, in the case of our data, such as the information searches are derived from projects developed in the institutional promotion programme for the training of researchers (PIBIC, adapting to the situational context and communicative that evokes.

Influence of teacher-directed scientific inquiry on students' primal inquiries in two science classrooms

Science.gov (United States)

Stone, Brian Andrew

Scientific inquiry is widely used but pervasively misunderstood in elementary classrooms. The use of inquiry is often attached to direct instruction models of teaching, or is even passed as textbook readings or worksheets. Previous literature on scientific inquiry suggests a range or continuum beginning with teacher-directed inquiry on one extreme, which involves a question, process, and outcome that are predetermined by the teacher. On the other end of the continuum is an element of inquiry that is extremely personal and derived from innate curiosity without external constraints. This authentic inquiry is defined by the study as primal inquiry. If inquiry instruction is used in the elementary classroom, it is often manifested as teacher-directed inquiry, but previous research suggests the most interesting, motivating, and lasting content is owned by the individual and exists within the individual's own curiosity, questioning and processes. Therefore, the study examined the impact of teacher-directed inquiry in two elementary fourth grade classrooms on climate-related factors including interest, motivation, engagement, and student-generated inquiry involvement. The study took place at two elementary classrooms in Arizona. Both were observed for ten weeks during science instruction over the course of one semester. Field notes were written with regard for the inquiry process and ownership, along with climate indicators. Student journals were examined for evidence of primal inquiry, and twenty-two students were interviewed between the two classrooms for evidence of low climate-related factors and low inquiry involvement. Data from the three sources were triangulated. The results of this qualitative study include evidence for three propositions, which were derived from previous literature. Strong evidence was provided in support of all three propositions, which suggest an overall negative impact on climate-related factors of interest, motivation, and engagement for

To test the effect of an Appreciative Inquiry (AI) quality improvement strategy on clinical quality management and practice development outcomes. Appreciative inquiry enables the discovery of shared motivations, envisioning a transformed future, and learning around the implementation of a change process. Thirty diverse primary care practices were randomly assigned to receive an AI-based intervention focused on a practice-chosen topic and on improving preventive service delivery (PSD) rates. Medical-record review assessed change in PSD rates. Ethnographic field notes and observational checklist analysis used editing and immersion/crystallization methods to identify factors affecting intervention implementation and practice development outcomes. The PSD rates did not change. Field note analysis suggested that the intervention elicited core motivations, facilitated development of a shared vision, defined change objectives, and fostered respectful interactions. Practices most likely to implement the intervention or develop new practice capacities exhibited 1 or more of the following: support from key leader(s), a sense of urgency for change, a mission focused on serving patients, health care system and practice flexibility, and a history of constructive practice change. An AI approach and enabling practice conditions can lead to intervention implementation and practice development by connecting individual and practice strengths and motivations to the change objective.

Report on carcinogens monograph on cumene.

Science.gov (United States)

2013-09-01

The National Toxicology Program conducted a cancer evaluation on cumene for possible listing in the Report on Carcinogens (RoC). The cancer evaluation is captured in the RoC monograph, which was peer reviewed in a public forum. The monograph consists of two components: (Part 1) the cancer evaluation, which reviews the relevant scientific information, assesses its quality, applies the RoC listing criteria to the scientific information, and provides the NTP recommendation for listing status for cumene in the RoC, and (Part 2) the substance profile proposed for the RoC, containing the NTP's listing status recommendation, a summary of the scientific evidence considered key to reaching that decision, and data on properties, use, production, exposure, and Federal regulations and guidelines to reduce exposure to cumene. This monograph provides an assessment of the available scientific information on cumene, including human exposure and properties, disposition and toxicokinetics, cancer studies in experimental animals, and studies of mechanisms and other related effects, including relevant toxicological effects, genetic toxicology, and mechanisms of carcinogenicity. From this assessment, the NTP recommended that cumene be listed as reasonably anticipated to be a human carcinogen in the RoC based on sufficient evidence from studies in experimental animals, which found that cumene exposure caused lung tumors in male and female mice and liver tumors in female mice. Several proposed mechanisms of carcinogenesis support the relevance to humans of the lung and liver tumors observed in experimental animals. Specifically, there is evidence that humans and experimental animals metabolize cumene through similar metabolic pathways. In addition, mutations of the K-ras oncogene and p53 tumor-suppressor gene observed in cumene-induced lung tumors in mice, along with altered expression of many other genes, resemble molecular alterations found in human lung and other cancers.

Nichols, Kim; Burgh, Gilbert; Kennedy, Callie

2017-02-01

Developing students' skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students' discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students' questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum.

Teachers' Language on Scientific Inquiry: Methods of teaching or methods of inquiry?

Science.gov (United States)

Gyllenpalm, Jakob; Wickman, Per-Olof; Holmgren, Sven-Olof

2010-06-01

With a focus on the use of language related to scientific inquiry, this paper explores how 12 secondary school science teachers describe instances of students' practical work in their science classes. The purpose of the study was to shed light on the culture and traditions of secondary school science teaching related to inquiry as expressed in the use of language. Data consisted of semi-structured interviews about actual inquiry units used by the teachers. These were used to situate the discussion of their teaching in a real context. The theoretical background is socio-cultural and pragmatist views on the role of language in science learning. The analysis focuses on two concepts of scientific inquiry: hypothesis and experiment. It is shown that the teachers tend to use these terms with a pedagogical function thus conflating methods of teaching with methods of inquiry as part of an emphasis on teaching the children the correct explanation. The teachers did not prioritise an understanding of scientific inquiry as a knowledge goal. It discusses how learners' possibilities to learn about the characteristics of scientific inquiry and the nature of science are affected by an unreflective use of everyday discourse.

2014-10-28

The European Directive 2004/24/EC introducing a simplified registration procedure for traditional herbal medicinal products, plays an important role in harmonising the current legislation framework for all herbal medicinal products in the European Union (EU). Although substantial achievements have been made under the new scheme, only a limited number of herbal medicinal products from non-European traditions commonly used in Europe have been registered. Therefore, identification of the obstacles, and determination of appropriate means to overcome the major challenges in the registration of non-European traditional herbal medicinal products are of critical importance for the EU herbal medicinal product market. The primary aims of this study were to understand the key issues and obstacles to registration of non-European traditional herbal medicinal products within the EU. The findings may identify the need for more attention on the Community herbal monographs elaborated by the Herbal Medicinal Products Committee (HMPC), as well as further evidence based scientific research on non-European herbal substances/preparations by the scientific community. A systematic evaluation of the herbal substances and preparations included in Community herbal monographs and public statements has been carried out. The focus was herbal substances and preparations derived from non-European traditions. Of the 109 adopted Community herbal monographs, 10 are herbal substances used in Chinese traditional medicine. Where the HMPC issued a public statement because it was unable to elaborate a monograph more than half-involved herbal substances/preparations from non-European traditions. The main reasons herbal substances/preparations from non-European traditions were not accepted for inclusion in the Community herbal monographs have been identified as due to unfulfilled requirements of Directive 2004/24/EC. The most common reasons were the lack of evidence to demonstrate a 15-year minimum

The implementation of the inquiry laboratory based project to enhance scientific inquiry literacy of prospective biology teachers in Microbiology course has been done. The inquiry lab based project was designed by three stages were debriefing of basic microbiology lab skills, guided inquiry and free inquiry respectively. The Study was quasi experimental with control group pretest-posttest design. The subjects were prospective biology teachers consists of 80 students. The scientific inquiry literacy instrument refers to ScInqLiT by Wenning. The results showed that there was significant difference of scientific inquiry literacy posttest scores between experiment and control (α 0,05) and was obtained N-gain score was 0.49 (medium) to experiment and 0.24 (low) to control. Based on formative assessment showed that development of student’s scientific attitude, research and microbiology lab skills during conducting project were increased. Student’s research skills especially in identification of variables, constructing a hypothesis, communicating and concluding were increased. During implementation of inquiry project also showed that they carried out mind and hands-on and so collaborative group investigation lab activities. Our findings may aid in reforming higher-education, particularly in microbiology laboratory activities to better promote scientific inquiry literacy, scientific attitude, research and laboratory skills.

Revisiting an open access monograph experiment: measuring citations and tweets 5 years later.

Science.gov (United States)

Snijder, Ronald

An experiment run in 2009 could not assess whether making monographs available in open access enhanced scholarly impact. This paper revisits the experiment, drawing on additional citation data and tweets. It attempts to answer the following research question: does open access have a positive influence on the number of citations and tweets a monograph receives, taking into account the influence of scholarly field and language? The correlation between monograph citations and tweets is also investigated. The number of citations and tweets measured in 2014 reveal a slight open access advantage, but the influence of language or subject should also be taken into account. However, Twitter usage and citation behaviour hardly overlap.

Fan edits and the legacy of The Phantom Edit

Directory of Open Access Journals (Sweden)

Joshua Wille

2014-09-01

Full Text Available A fan edit can generally be defined as an alternative version of a film or television text created by a fan. It offers a different viewing experience, much as a song remix offers a different listening experience. The contemporary wave of fan edits has emerged during the remix zeitgeist of digital media and at a time when digital video editing technology has become more affordable and popular. The increasing number of alternative versions of films and the works of revisionist Hollywood filmmakers such as George Lucas have contributed to a greater public understanding of cinema as a fluid medium instead of one that exists in a fixed form. The Phantom Edit (2000, a seminal fan edit based on Lucas's Star Wars Episode I: The Phantom Menace (1999, inspired new ranks of fan editors. However, critics have misunderstood fan edits as merely the work of disgruntled fans. In order to provide a critical and historical basis for studies in fan editing as a creative practice, I examine previous interpretations of fan edits in the context of relevant contemporary works, and I use an annotated chronology of The Phantom Edit to trace its influence on subsequent fan editing communities and uncover their relationship with intellectual property disputes.

2012-06-01

Although reductions in lead (Pb) exposure for the U.S. population have resulted in lower blood Pb levels over time, epidemiological studies continue to provide evidence of health effects at lower and lower blood Pb levels. Low-level Pb was selected for evaluation by the National Toxicology Program (NTP) because of (1) the availability of a large number of epidemiological studies of Pb, (2) a nomination by the National Institute for Occupational Safety and Health for an assessment of Pb at lower levels of exposure, and (3) public concern for effects of Pb in children and adults. This evaluation summarizes the evidence in humans and presents conclusions on health effects in children and adults associated with low-level Pb exposure as indicated by less than 10 micrograms of Pb per deciliter of blood (Monograph on Health Effects of Low-Level Lead. The document and appendices are available at http://ntp.niehs.nih.gov/go/evals. This document provides background on Pb exposure and includes a review of the primary epidemiological literature for evidence that low-level Pb is associated with neurological, immunological, cardiovascular, renal, and/or reproductive and developmental effects.

2008-01-01

To describe the provision of pediatric drug safety information in a national formulary of manufacturers' drug product monographs. We performed a cross-sectional evaluation of comprehensive product monographs contained in the 2005 Canadian Compendium of Pharmaceuticals and Specialities (CPS). We abstracted data describing indications for prescription, statements about pediatric safety, available preparations, and provision of dosing guidelines. For each monograph we classified pediatric safety data as either present, present but limited or absent. We then described the pediatric safety data in CPS monographs for drugs listed in the published formulary of the Hospital for Sick Children, Toronto, Ontario, Canada. A total of 2232 product monographs were screened; 684 were excluded and 1548 (66%) were further analyzed. 1462 (94%) had indications that did not exclude children. Pediatric safety information was present in 592 (38%), present but limited in 148 (10%), and absent in 808 (52%) drug monographs. Safety statements were absent in 224 (14%) drug monographs that provided both dosing guidelines and formulations suitable for administration to children, and in 214 (52%) of 411 drugs in the pediatric hospital formulary. We evaluated a widely available national source of pediatric prescribing information. Safety data for children was not mentioned in more than half of the product monographs. Moreover, the provision of safety data was discordant with indications for prescription, the availability of pediatric formulations, and dosing guidelines within the monographs, and with inclusion in a pediatric hospital formulary. Our study suggests that the presentation of pediatric safety data in drug product monographs can be improved to better inform prescribing and to optimize pharmacotherapy in children.

Big inquiry

Energy Technology Data Exchange (ETDEWEB)

Wynne, B [Lancaster Univ. (UK)

1979-06-28

The recently published report entitled 'The Big Public Inquiry' from the Council for Science and Society and the Outer Circle Policy Unit is considered, with especial reference to any future enquiry which may take place into the first commercial fast breeder reactor. Proposals embodied in the report include stronger rights for objectors and an attempt is made to tackle the problem that participation in a public inquiry is far too late to be objective. It is felt by the author that the CSS/OCPU report is a constructive contribution to the debate about big technology inquiries but that it fails to understand the deeper currents in the economic and political structure of technology which so influence the consequences of whatever formal procedures are evolved.

Also noted was that 1 bromopropane, either directly or via reactive metabolites, caused molecular alterations that typically are associated with carcinogenesis, including genotoxicity, oxidative stress, and glutathione depletion. These alterations, observed in mainly in vitro and toxicity studies in rodents, are relevant to possible mechanisms of human carcinogenicity and support the relevance of the cancer studies in

Approaches to Inquiry Teaching: Elementary teacher's perspectives

Ireland, Joseph; Watters, James J.; Lunn Brownlee, J.; Lupton, Mandy

2014-07-01

Learning science through the process of inquiry is advocated in curriculum documents across many jurisdictions. However, a number of studies suggest that teachers struggle to help students engage in inquiry practices. This is not surprising as many teachers of science have not engaged in scientific inquiry and possibly hold naïve ideas about what constitutes scientific inquiry. This study investigates teachers' self-reported approaches to teaching science through inquiry. Phenomenographic interviews undertaken with 20 elementary teachers revealed teachers identified six approaches to teaching for inquiry, clustered within three categories. These approaches were categorized as Free and Illustrated Inquiries as part of an Experience-centered category, Solution and Method Inquiries as part of a Problem-centered category, and Topic and Chaperoned Inquiries as part of a Question-centered category. This study contributes to our theoretical understanding of how teachers approach Inquiry Teaching and suggests fertile areas of future research into this valued and influential phenomenon broadly known as 'Inquiry Teaching'.

Brown, Patrick L.; Abell, Sandra K.; Demir, Abdulkadir; Schmidt, Francis J.

2006-09-01

The purposes of this study were to (a) gain an understanding of the views of inquiry held by faculty members involved in undergraduate science teaching and (b) describe the challenges, constraints, and opportunities that they perceived in designing and teaching inquiry-based laboratories. Participants included 19 college professors, representing both life and physical science disciplines, from (a) 2-year community college, (b) small, private nonprofit liberal arts college, (c) public master's granting university, and (d) public doctoral/research extensive university. We collected data through semistructured interviews and applied an iterative data analysis process. College science faculty members held a full and open inquiry view, seeing classroom inquiry as time consuming, unstructured, and student directed. They believed that inquiry was more appropriate for upper level science majors than for introductory or nonscience majors. Although faculty members valued inquiry, they perceived limitations of time, class size, student motivation, and student ability. These limitations, coupled with their view of inquiry, constrained them from implementing inquiry-based laboratories. Our proposed inquiry continuum represents a broader view of inquiry that recognizes the interaction between two dimensions of inquiry: (a) the degree of inquiry and (b) the level of student directedness, and provides for a range of inquiry-based classroom activities.

The influence of an inquiry professional development program on secondary science teachers' conceptions and use of inquiry teaching

Lotter, Christine

2005-11-01

This research investigated nine secondary science teachers' conceptions and use of inquiry teaching throughout a year-long professional development program. The professional development program consisted of a two-week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Teachers' conceptions of inquiry teaching were established through both qualitative interviews and a quantitative instrument given before and after the summer institute and again at the end of the academic year. Videotapes of all nine teachers presenting inquiry lessons in their own classrooms were evaluated using an observation protocol that measured the teachers' degree of reform teaching. Three of the teachers were chosen for an in-depth case study of their classroom teaching practices. Data collected from each of the case study teachers included videotapes from classroom observations, responses to an inquiry survey, and transcripts from two additional qualitative interviews. Students' responses to their teachers' use of inquiry teaching were also investigated in the case study classrooms. Through their participation in the professional development experience, the teachers gained a deeper understanding of how to implement inquiry practices in their classrooms. The teachers gained confidence and practice with inquiry methods through developing and presenting their institute-developed inquiry lessons, through observing other teachers' lessons, and participating as students in the workshop inquiry activities. Data analysis revealed that the teachers' knowledge of inquiry was necessary but not sufficient for their implementation of inquiry teaching practices. The teachers' conceptions of science, their students, effective teaching practices, and the purpose of education were found to have a direct effect on the type and amount of inquiry instruction performed in the high school classrooms. The research findings suggest that

The Economic and Social Research Council has studied four major environmental public inquiries, including Sizewell-B. This report summarizes some of the observations of the Sizewell Inquiry Review Project which has been analyzing the context, content and conduct of the Sizewell-B Inquiry. Although public inquiries in Britain have an important function in building public trust in planning decisions where opinions are divided and independent advice is needed, one outcome of the Sizewell-B Inquiry may be a streamlining of the inquiry process, eg by prior examination of policy matters, leaving the Inquiry to consider specifically site-related matters only.

Abundant off-target edits from site-directed RNA editing can be reduced by nuclear localization of the editing enzyme.

Vallecillo-Viejo, Isabel C; Liscovitch-Brauer, Noa; Montiel-Gonzalez, Maria Fernanda; Eisenberg, Eli; Rosenthal, Joshua J C

2018-01-02

Site-directed RNA editing (SDRE) is a general strategy for making targeted base changes in RNA molecules. Although the approach is relatively new, several groups, including our own, have been working on its development. The basic strategy has been to couple the catalytic domain of an adenosine (A) to inosine (I) RNA editing enzyme to a guide RNA that is used for targeting. Although highly efficient on-target editing has been reported, off-target events have not been rigorously quantified. In this report we target premature termination codons (PTCs) in messages encoding both a fluorescent reporter protein and the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein transiently transfected into human epithelial cells. We demonstrate that while on-target editing is efficient, off-target editing is extensive, both within the targeted message and across the entire transcriptome of the transfected cells. By redirecting the editing enzymes from the cytoplasm to the nucleus, off-target editing is reduced without compromising the on-target editing efficiency. The addition of the E488Q mutation to the editing enzymes, a common strategy for increasing on-target editing efficiency, causes a tremendous increase in off-target editing. These results underscore the need to reduce promiscuity in current approaches to SDRE.

Tuberculosis (TB) remains a highly prevalent and potentially severe disease. However, since 2002 the annual incidence has been decreasing both worldwide and in Spain, where the incidence varies widely between regions. The main objective of this study is to describe the experience of a monographic TB unit in a second level hospital. A descriptive study was carried out which included all cases of TB diagnosed in a monographic unit of a secondary hospital between 2003 and 2011. Demographic, clinical, epidemiological and microbiological data were recorded. We analyzed 500 TB cases and found an increasing annual incidence in all subgroups, including native and immigrant populations. Most cases (63.8%) were male, with a median age of 36 years (range 8 months-90 years). In total, 39.8% of patients were foreign born. Coinfection with human immunodeficiency virus was found in 11% of cases. The pulmonary form was most frequently diagnosed (63.8%). Overall mortality was 5.8% with no significant differences between groups (including foreign born and human immunodeficiency virus positive patients). Although TB incidence is globally decreasing, in our study we found an increasing number of cases in recent years in all subgroups, which can be explained by this being a monographic unit with an intensive contact tracing program.

Full Text Available The advent of open access (OA publishing presents welcome new opportunities for reducing the barriers of cost and time to the dissemination of research work in UK universities. However, it does present some challenges to the traditional model of monograph publication in the humanities and social sciences. In common with many other academic institutions, the University of Sussex is developing policies that will permit it to embrace OA publication. This paper describes how, in doing this, Sussex is addressing the challenges associated with OA to ensure that the careers of doctoral students, academics and researchers are not affected adversely by the change in the publishing landscape for monographs both in the UK and internationally.

Infusing Authentic Inquiry into Biotechnology

Science.gov (United States)

Hanegan, Nikki L.; Bigler, Amber

2009-10-01

Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced

Possible ambiguities when testing viscosity in compendial monographs - characterisation of grades of cellulose ethers.

Science.gov (United States)

Doelker, E

2010-10-01

The European Pharmacopoeia (Ph. Eur.) monographs for the water-soluble cellulose ethers require viscosity determination, either in the "Tests" section or in the non-mandatory "Functionality-related characteristics" section. Although the derivatives are chemically closely related and used for similar applications, the viscosity tests strongly differ. Some monographs generically speak of the rotating viscometer method (2.2.10) and a fixed shear rate (e.g. 10 s-1), which would necessitate an absolute measuring system, while others recommend the capillary viscometer method for product grades of less than 600 mPa∙s and the rotating viscometer method and given operating conditions for grades of higher nominal viscosity. Viscometer methods also differ between the United States Pharmacopeia/National Formulary (USP/NF) and the Japanese Pharmacopoeia (JP) monographs. In addition, for some cellulose ethers the tests sometimes diverge from one pharmacopoeia to the other, although the three compendiums are in a harmonisation process. But the main issue is that the viscometer methods originally employed by the product manufacturers are often not those described in the corresponding monographs and generally vary from one manufacturer to the other. The aim of this study was therefore to investigate whether such a situation could invalidate the present pharmacopoeial requirements. 2 per cent solutions of several viscosity grades of hydroxyethylcellulose, hypromellose and methylcellulose were prepared and their (apparent) viscosity determined using both relative and absolute viscometer methods. The viscometer method used not only affects the measured viscosity but experimental values generally do not correspond to the product nominal viscosities. It emerges that, in contrast to Newtonian solutions (i.e. those of grades of up to ca. 50 mPa∙s nominal viscosity), some of the viscometer methods currently specified in the monographs are not able unambiguously to characterise the

2011-02-10

To describe the development and assessment of monographs as an assignment to incorporate evidence-based medicine (EBM) and pharmacoeconomic principles into a third-year pharmacoeconomic course. Eight newly FDA-approved drugs were assigned to 16 teams of students, where each drug was assigned to 2 teams. Teams had to research their drug, write a professional monograph, deliver an oral presentation, and answer questions posed by faculty judges. One team was asked to present evidence for inclusion of the drug into a formulary, while another team presented evidence against inclusion. The teams' average score on the written report was 99.1%; on the oral presentation, 92.5%, and on the online quiz given at the end of the presentations, 77%. Monographs are a successful method of incorporating and integrating learning across different concepts, as well as increasing relevance of pharmacoeconomics in the PharmD curriculum.

Information for physicians and pharmacists about drugs that might cause dry mouth: a study of monographs and published literature.

Science.gov (United States)

Nguyen, Caroline T; MacEntee, Michael I; Mintzes, Barbara; Perry, Thomas L

2014-01-01

Over three-quarters of the older population take medications that can potentially cause dry mouth. Physicians or pharmacists rarely inform patients about this adverse effect and its potentially severe damage to the teeth, mouth and general health. The objectives of this study were to (1) identify warnings in the literature about dry mouth associated with the most frequently prescribed pharmaceutical products in Canada; and (2) consider how this information might be obtained by physicians, pharmacists and patients. Monographs on the 72 most frequently prescribed medications during 2010 were retrieved from the Compendium of Pharmaceuticals and Specialties (CPS, a standard drug information reference for physicians and pharmacists), the National Library of Medicine's 'DailyMed' database, directly from the manufacturers, and from a systematic search of biomedical journals. The CPS provided monographs for 43% of the medications, and requests to manufacturers produced the remaining monographs. Mentions of dry mouth were identified in 61% of the products (43% amongst CPS monographs; an additional 43% amongst manufacturers' monographs; 7% in the DailyMed database and 7% from biomedical journals); five medications had contradictory reports in different monographs. Nearly two-thirds (61%) of the most commonly prescribed medications can cause dry mouth, yet warnings about this adverse effect and its potentially serious consequences are not readily available to physicians, pharmacists, dentists or patients.

‘The Returned’: on the future of monographic books

2014-04-01

Full Text Available This article evaluates the current state of academic book publishing based on the findings of the Hybrid Publishing Lab's business model research. With students relying more and more on Google and Wikipedia, the role of books within today's university studies is a difficult one. From the perspective of publishers, open access (OA embracing the digital is seen as one potential way to bridge this gap between online search engines and traditional monographs. To illustrate this further, the article delivers an overview of its findings, which highlight changes in academic publishing: publishers have switched their emphasis from delivering a product to creating a service, whereby the author rather than the reader becomes their most focused-on customer. Research frameworks, funding and conventions about academic careers, however, often still need to adjust to this new development. If these frameworks acknowledge and foster OA publishing, and new experiments with collaborative book productions flourish, the monograph will have a future.

The Climatic Impact Assessment Program (CIAP) of the U.S. Department of Transportation is charged with the 'assessment' of the impact of future aircraft fleets and other vehicles operating in, or transiting through, the stratosphere. CIAP monograph 1 gives a survey, largely from an experimental standpoint, of what is known in 1974 about the unperturbed stratosphere with respect to an application to stratospheric flight. It reviews the overall structure of the stratosphere, its origin in terms of ozone photochemistry, solar irradiance and overall radiative energy balance, other chemically reactive minor species, and atmospheric motions on a variety of scales of time and distance. The limitations of our understanding are emphasized in the presentation. Also, the monograph examines briefly what is known about the effect of massive injections of nitrogen oxides (from atmospheric nuclear explosions) and sulfur oxides (from major volcanic eruptions)

How Select Groups of Preservice Science Teachers with Inquiry Orientations View Teaching and Learning Science through Inquiry

Science.gov (United States)

Ward, Peggy

Although hailed as a powerful form of instruction, in most teaching and learning contexts, inquiry-based instruction is fraught with ambiguous and conflicting definitions and descriptions. Yet little has been written about the experiences preservice science teacher have regarding their learning to teach science through inquiry. This project sought to understand how select preservice secondary science teachers enrolled in three UTeach programs in Arkansas conceptualize inquiry instruction and how they rationalize its value in a teaching and learning context. The three teacher education programs investigated in this study are adoption sites aligned with the UTeach Program in Austin, TX that distinguishes itself in part by its inquiry emphasis. Using a mixed method investigation design, this study utilized two sources of data to explore the preservice science teachers' thinking. In the first phase, a modified version of the Pedagogy of Science teaching Tests (POSTT) was used to identify select program participants who indicated preferences for inquiry instruction over other instructional strategies. Secondly, the study used an open-ended questionnaire to explore the selected subjects' beliefs and conceptions of teaching and learning science in an inquiry context. The study also focused on identifying particular junctures in the prospective science teachers' education preparation that might impact their understanding about inquiry. Using a constant comparative approach, this study explored 19 preservice science teachers' conceptions about inquiry. The results indicate that across all levels of instruction, the prospective teachers tended to have strong student-centered teaching orientations. Except subjects in for the earliest courses, subjects' definitions and descriptions of inquiry tended toward a few of the science practices. More advanced subjects, however, expressed more in-depth descriptions. Excluding the subjects who have completed the program, multiple

Our choice of energy sources has important consequences for the economy and the environment. Nuclear energy is a controversial energy source, subject to much public debate. Most individuals find it difficult to decide between conflicting claims and allegations in a variety of technical subjects. Under these circumstances, knowledge of various relevant inquiries can be helpful. This publication summarizes the composition and major findings of more than thirty nuclear energy inquiries. Most of the these are Canadian, but others are included where they have relevance. The survey shows that, contrary to some claims, virtually every aspect of nuclear energy has been subject to detailed scrutiny. The inquiries' reports include many recommendations on how nuclear energy can be exploited safely, but none rejects it as an acceptable energy source when needed. (Author) 38 refs

[The HMPC monograph on Hypericum: Background, development, contents].

Science.gov (United States)

Länger, Reinhard

2010-12-01

The adoption of the EU community monograph on Hypericum constitutes a milestone in the process of harmonisation of herbal medicinal products within the European Community. The assessment of the published clinical data revealed that for two types of extracts the evidence of the efficacy in mild to moderate depressive episodes compared to placebo or standard medication was found to be acceptable. Additionally, a sufficient efficacy in relapse prophylaxis could be demonstrated for these two herbal preparations. For some other dry extracts, the efficacy in the short-term treatment of symptoms in mild depressive disorders was found to be substantiated. Short-term treatment with preparations containing low amounts of hyperforin did not increase cytochrome P450 enzyme activity. Therefore the oral administration of traditional herbal preparations is restricted to two weeks. In the case that an applicant demonstrates that the daily intake of hyperforin is below 1 mg the warnings on interactions may be omitted in traditional herbal medicinal products. Additionally the cutaneous administration of traditional liquid herbal preparations for the traditional use in symptomatic treatment of minor inflammations of the skin and as an aid in healing minor wounds was included in the monograph.

Computerized edition is essential for data processing exploitation. When a more or less complex edition program is required for each task, then the need for a general edition program become obvious. The aim of this study is to create a general edition program. Universal programs are capable to execute numerous and varied tasks. For a more precise processing, the execution of which is frequently required, the use of a specialized program is preferable because, contradictory to the universal program, it goes straight to the point [fr

Leblebicioglu, G.; Abik, N. M.; Capkinoglu, E.; Metin, D.; Dogan, E. Eroglu; Cetin, P. S.; Schwartz, R.

2017-08-01

Scientific inquiry is widely accepted as a method of science teaching. Understanding its characteristics, called Nature of Scientific Inquiry (NOSI), is also necessary for a whole conception of scientific inquiry. In this study NOSI aspects were taught explicitly through student inquiries in nature in two summer science camps. Students conducted four inquiries through their questions about surrounding soil, water, plants, and animals under the guidance of university science educators. At the end of each investigation, students presented their inquiry. NOSI aspects were made explicit by one of the science educators in the context of the investigations. Effectiveness of the science camp program and its retention were determined by applying Views of Scientific Inquiry (VOSI-S) (Schwartz et al. 2008) questionnaire as pre-, post-, and retention test after two months. The patterns in the data were similar. The science camp program was effective in developing three of six NOSI aspects which were questions guide scientific research, multiple methods of research, and difference between data and evidence. Students' learning of these aspects was retained. Discussion about these and the other three aspects is included in the paper. Implications of differences between school and out-of-school science experiences are also discussed.

Inquiry-based instruction in biology has been the focus of educational research conducted by Unnes biology department students in collaboration with their university supervisors. This study aimed to describe the methodological aspects, inquiry teaching methods critically, and to analyse the results claims, of the selected four student research reports, grounded in inquiry, based on the database of Unnes biology department 2014. Four experimental quantitative research of 16 were selected as research objects by purposive sampling technique. Data collected through documentation study was qualitatively analysed regarding methods used, quality of inquiry syntax, and finding claims. Findings showed that the student research was still the lack of relevant aspects of research methodology, namely in appropriate sampling procedures, limited validity tests of all research instruments, and the limited parametric statistic (t-test) not supported previously by data normality tests. Their consistent inquiry syntax supported the four mini-thesis claims that inquiry-based teaching influenced their dependent variables significantly. In other words, the findings indicated that positive claims of the research results were not fully supported by good research methods, and well-defined inquiry procedures implementation.

Matthias Catón

2006-03-01

Full Text Available The book Rethinking Social Inquiry, edited by Henry E. BRADY and David COLLIER, is a response to a book by KING, KEOHANE and VERBA (1994 that aimed to introduce quantitative standards to qualitative research. The authors of the book reviewed here criticize many of the suggestions made there because they argue that qualitative research requires other tools. Nevertheless, they agree that the foundations of research design are similar. The book comprises a comprehensive critique of mainstream quantitative techniques, describes a set of qualitative tools for research, and addresses issues of how to combine qualitative and quantitative approaches to maximize analytical leverage. It is an excellent contribution to the methodological debate in the social sciences. URN: urn:nbn:de:0114-fqs0602309

Naturalistic Inquiry in E-Learning Research

Directory of Open Access Journals (Sweden)

Shirley Agostinho

2005-03-01

Full Text Available In this article, the author explains how and why one particular qualitative research approach, the naturalistic inquiry paradigm, was implemented in an e-learning research study that investigated the use of the World Wide Web technology in higher education. A framework is presented that situates the research study within the qualitative research literature. The author then justifies how the study was compliant with naturalistic inquiry and concludes by presenting a model for judging the quality of such research. The purpose of this article is to provide an example of how naturalistic inquiry can be implemented in e-learning research that can serve as a guide for researchers undertaking this form of qualitative inquiry. As such, the focus of the article is to illustrate how methodological issues pertaining to naturalistic inquiry were addressed and justified to represent a rigorous research approach rather than presenting the results of the research study.

First-Year Teachers’ Uphill Struggle to Implement Inquiry Instruction

Directory of Open Access Journals (Sweden)

Tanya Chichekian

2016-05-01

Full Text Available This longitudinal study of six first-year teachers focused on conceptualizations of inquiry-based pedagogy, self-efficacy for inquiry-based teaching, and its actual enactment. Data included a self-report survey of self-efficacy for inquiry-based instruction, individual interviews at the beginning and end of the year, and five distributed classroom observations. At year’s end, self-efficacy for inquiry teaching declined, as did frequencies of concepts teachers used to describe inquiry enactment. Inquiry descriptions reflected a set of interrelated procedures more than inquiry as conceptual knowledge. Novice teachers were observed least enacting pedagogical actions that required enabling students to communicate findings and the most in student engagement; however, over time frequencies of student engagement declined. Consistent patterns were observed between shifts in self-efficacy and inquiry enactment and shifts between self-efficacy and conceptualizations of inquiry enactment. We found beginning steps toward links between teacher’s conceptualizations and classroom practice.

Theoretical perspectives on narrative inquiry.

Science.gov (United States)

Emden, C

1998-04-01

Narrative inquiry is gaining momentum in the field of nursing. As a research approach it does not have any single heritage of methodology and its practitioners draw upon diverse sources of influence. Central to all narrative inquiry however, is attention to the potential of stories to give meaning to people's lives, and the treatment of data as stories. This is the first of two papers on the topic and addresses the theoretical influences upon a particular narrative inquiry into nursing scholars and scholarship. The second paper, Conducting a narrative analysis, describes the actual narrative analysis as it was conducted in this same study. Together, the papers provide sufficient detail for others wishing to pursue a similar approach to do so, or to develop the ideas and procedures according to their own way of thinking. Within this first theoretical paper, perspectives from Jerome Bruner (1987) and Wade Roof (1993) are outlined. These relate especially to the notion of stories as 'imaginative constructions' and as 'cultural narratives' and as such, highlight the profound importance of stories as being individually and culturally meaningful. As well, perspectives on narrative inquiry from nursing literature are highlighted. Narrative inquiry in this instance lies within the broader context of phenomenology.

This monograph is one of several published in a series by the Bureau International des Poids et Mesures (BIPM) on behalf of the Consultative Committee for Ionizing Radiation (Comite Consultatif des Rayonnements Ionisants, CCRI). The aim of this series of publications is to review topics that are of importance for the measurement of ionizing radiation and especially of radioactivity, in particular those techniques normally used by participants in international comparisons. The purpose of this monograph, number 5 in the series, is to present the recommended values of nuclear and decay data for a wide range of radionuclides. Activity measurements for more than sixty-three of these radionuclides have already been the subject of comparisons under the auspices of Section II (dedicated to the Measurement of radionuclides) of the CCRI. The material for this monograph is now covered in seven volumes. The first two volumes contain the primary recommended data relating to half-lives, decay modes, x-rays, gamma-rays, electron emissions; alpha- and beta-particle transitions and emissions, and their uncertainties for a set of sixty-eight radionuclides, Volume 1 for those radionuclides with mass number up to and including 150 and Volume 2 for those radionuclides with mass number over 150. Volume 3 contains the equivalent data for twenty-six additional radionuclides as listed and re-evaluations for 125 Sb and 153 Sm.

Bell, Thorsten; Urhahne, Detlef; Schanze, Sascha; Ploetzner, Rolf

2010-02-01

Collaborative inquiry learning is one of the most challenging and exciting ventures for today's schools. It aims at bringing a new and promising culture of teaching and learning into the classroom where students in groups engage in self-regulated learning activities supported by the teacher. It is expected that this way of learning fosters students' motivation and interest in science, that they learn to perform steps of inquiry similar to scientists and that they gain knowledge on scientific processes. Starting from general pedagogical reflections and science standards, the article reviews some prominent models of inquiry learning. This comparison results in a set of inquiry processes being the basis for cooperation in the scientific network NetCoIL. Inquiry learning is conceived in several ways with emphasis on different processes. For an illustration of the spectrum, some main conceptions of inquiry and their focuses are described. In the next step, the article describes exemplary computer tools and environments from within and outside the NetCoIL network that were designed to support processes of collaborative inquiry learning. These tools are analysed by describing their functionalities as well as effects on student learning known from the literature. The article closes with challenges for further developments elaborated by the NetCoIL network.

Science Inquiry as Knowledge Transformation: Investigating Metacognitive and Self-regulation Strategies to Assist Students in Writing about Scientific Inquiry Tasks

Science.gov (United States)

Collins, Timothy A.

2011-12-01

Science inquiry is central to the science education reform efforts that began in the early 1990's. It is both a topic of instruction and a process to be experienced. Student engagement in the process of scientific inquiry was the focus of this study. The process of scientific inquiry can be conceived as a two-part task. In the initial part of the task, students identify a question or problem to study and then carry out an investigation to address the issue. In the second part of the task, students analyze their data to propose explanations and then report their findings. Knowing that students struggle with science inquiry tasks, this study sought to investigate ways to help students become more successful with the communication demands of science inquiry tasks. The study took place in a high school chemistry class. Students in this study completed a total of three inquiry tasks over the course of one school year. Students were split into four experimental groups in order to determine the effect of goal setting, metacognitive prompts, and sentence stems on student inquiry tasks. The quality of the student written work was assessed using a scoring rubric familiar to the students. In addition, students were asked at four different times in the school year to respond to a self-efficacy survey that measured student self-efficacy for chemistry content and science inquiry processes. Student self-efficacy for the process of scientific inquiry was positive and did not change over the course of the study while student scores on the science inquiry tasks rose significantly. The metacognitive prompts and instruction in goal setting did not have any effect on student inquiry scores. Results related to the effect of the sentence stems were mixed. An analysis of student work indicated that students who received high marks on their initial inquiry task in this study were the ones that adopted the use of the sentence stems. Students who received low marks on their initial inquiry

Re-editing the paradigm of Cytidine (C) to Uridine (U) RNA editing.

Science.gov (United States)

Fossat, Nicolas; Tam, Patrick P L

2014-01-01

Cytidine (C) to Uridine (U) RNA editing is a post-trancriptional modification that until recently was known to only affect Apolipoprotein b (Apob) RNA and minimally require 2 components of the C to U editosome, the deaminase APOBEC1 and the RNA-binding protein A1CF. Our latest work has identified a novel RNA-binding protein, RBM47, as a core component of the editosome, which can substitute A1CF for the editing of ApoB mRNA. In addition, new RNA species that are subjected to C to U editing have been identified. Here, we highlight these recent discoveries and discuss how they change our view of the composition of the C to U editing machinery and expand our knowledge of the functional attributes of C to U RNA editing.

Ebola virus RNA editing depends on the primary editing site sequence and an upstream secondary structure.

Directory of Open Access Journals (Sweden)

Masfique Mehedi

Full Text Available Ebolavirus (EBOV, the causative agent of a severe hemorrhagic fever and a biosafety level 4 pathogen, increases its genome coding capacity by producing multiple transcripts encoding for structural and nonstructural glycoproteins from a single gene. This is achieved through RNA editing, during which non-template adenosine residues are incorporated into the EBOV mRNAs at an editing site encoding for 7 adenosine residues. However, the mechanism of EBOV RNA editing is currently not understood. In this study, we report for the first time that minigenomes containing the glycoprotein gene editing site can undergo RNA editing, thereby eliminating the requirement for a biosafety level 4 laboratory to study EBOV RNA editing. Using a newly developed dual-reporter minigenome, we have characterized the mechanism of EBOV RNA editing, and have identified cis-acting sequences that are required for editing, located between 9 nt upstream and 9 nt downstream of the editing site. Moreover, we show that a secondary structure in the upstream cis-acting sequence plays an important role in RNA editing. EBOV RNA editing is glycoprotein gene-specific, as a stretch encoding for 7 adenosine residues located in the viral polymerase gene did not serve as an editing site, most likely due to an absence of the necessary cis-acting sequences. Finally, the EBOV protein VP30 was identified as a trans-acting factor for RNA editing, constituting a novel function for this protein. Overall, our results provide novel insights into the RNA editing mechanism of EBOV, further understanding of which might result in novel intervention strategies against this viral pathogen.

Multilingualism is common offline, but we have a more limited understanding of the ways multilingualism is displayed online and the roles that multilinguals play in the spread of content between speakers of different languages. We take a computational approach to studying multilingualism using one of the largest user-generated content platforms, Wikipedia. We study multilingualism by collecting and analyzing a large dataset of the content written by multilingual editors of the English, German, and Spanish editions of Wikipedia. This dataset contains over two million paragraphs edited by over 15,000 multilingual users from July 8 to August 9, 2013. We analyze these multilingual editors in terms of their engagement, interests, and language proficiency in their primary and non-primary (secondary) languages and find that the English edition of Wikipedia displays different dynamics from the Spanish and German editions. Users primarily editing the Spanish and German editions make more complex edits than users who edit these editions as a second language. In contrast, users editing the English edition as a second language make edits that are just as complex as the edits by users who primarily edit the English edition. In this way, English serves a special role bringing together content written by multilinguals from many language editions. Nonetheless, language remains a formidable hurdle to the spread of content: we find evidence for a complexity barrier whereby editors are less likely to edit complex content in a second language. In addition, we find that multilinguals are less engaged and show lower levels of language proficiency in their second languages. We also examine the topical interests of multilingual editors and find that there is no significant difference between primary and non-primary editors in each language.

In this way, English serves a special role bringing together content written by multilinguals from many language editions. Nonetheless, language remains a formidable hurdle to the spread of content: we find evidence for a complexity barrier whereby editors are less likely to edit complex content in a second language. In addition, we find that multilinguals are less engaged and show lower levels of language proficiency in their second languages. We also examine the topical interests of multilingual editors and find that there is no significant difference between primary and non-primary editors in each language.

Coolabah, No.12, 2013, ISSN 1988-5946, Observatori: Centre d’Estudis Australians, Australian Studies Centre, Universitat de Barcelona 2 From a postcolonial studies perspective, this example reminds students of two key processes. First, students need to master the intellectual skills of the humanities in order to provide critical analysis of social situations. Secondly, students need to know that, as western scholars, they are as much part of any postcolonial problem as those in power, and therefore need to develop good reflective skills and to learn to think ‘otherwise’.

Pragmatic inquiry and creativity

DEFF Research Database (Denmark)

Gimmler, Antje

’Don’t block the road of inquiry” was the motto of Peirce and also Dewey situated inquiry in its ideal version in a democratic and cooperative community. Abduction became the key concept for the pragmatic and creative research process where the lonely engineer is substituted with intelligent...... collaborations of the many. Thus, inquiry is from a pragmatic understanding rather a social than a purely cognitive task. The paper will firstly give a sketch of this understanding of inquiry and creativity on the background of the theories of Peirce and Dewey and will draw some parallels to recent...... of Thevenot’s critical pragmatism this understanding might be naïve – not because this is an idealistic rather than a real-life scenario but because the idea of collaborative creativity and self-realization has actually become the driving force in a marked dominated organization of science and production...

Picardi, Ernesto; Regina, Teresa Maria Rosaria; Brennicke, Axel; Quagliariello, Carla

2007-01-01

The RNA Editing Database (REDIdb) is an interactive, web-based database created and designed with the aim to allocate RNA editing events such as substitutions, insertions and deletions occurring in a wide range of organisms. The database contains both fully and partially sequenced DNA molecules for which editing information is available either by experimental inspection (in vitro) or by computational detection (in silico). Each record of REDIdb is organized in a specific flat-file containing a description of the main characteristics of the entry, a feature table with the editing events and related details and a sequence zone with both the genomic sequence and the corresponding edited transcript. REDIdb is a relational database in which the browsing and identification of editing sites has been simplified by means of two facilities to either graphically display genomic or cDNA sequences or to show the corresponding alignment. In both cases, all editing sites are highlighted in colour and their relative positions are detailed by mousing over. New editing positions can be directly submitted to REDIdb after a user-specific registration to obtain authorized secure access. This first version of REDIdb database stores 9964 editing events and can be freely queried at http://biologia.unical.it/py_script/search.html.

Fullerton, G.D.; Kopp, D.T.; Waggener, R.G.; Webster, E.W.

1980-01-01

This book is the fifth in a series of monographs by the American Association of Physicists in Medicine (AAPM) and is a compendium of papers presented at an AAPM regional symposium conducted in San Antonio in July 1980. The book is divided into three sections: (1) biological fundamentals of ionizing radiation, (2) risk evaluation and reduction in three principle radiologic subspecialties (diagnostic radiology, nuclear medicine and radiation therapy), and (3) medical-legal implications. The first section includes a historical review of radiation biology, including a discussion of somatic and genetic effects and statistical approaches to risk estimates. The section on risk evaluation and reduction includes a good review of the units of exposure and activity including the international (SI) system employing the gray, becquerel, and seivert that respectively replace the rad, Curie, and rem. The unavoidable problem of legal responsibility and liability is the subject of the third, and last, section of the monograph. A chapter summarizing the legal history of medical irradiation also includes a glossary of pertinent legal terms. Recent court decisions that impact upon the clinical use of radiation are presented and discussed as well as proposed changes in federal guidelines that could have a large impact on the practice of medicine in general and radiology in particular

Analyzing students' attitudes towards science during inquiry-based lessons

Science.gov (United States)

Kostenbader, Tracy C.

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

Full Text Available This study shares the findings of a school-based Action Research project to explore how inquiry-based science practical lessons designed using the Flipped Science Inquiry@CGS classroom pedagogical model influence the way students learn scientific knowledge and also students' development of 21st century competencies, in particular, in the area of Knowledge Construction. Taking on a broader definition of the flipped classroom pedagogical model, the Flipped Science Inquiry@CGS framework adopts a structure that inverted the traditional science learning experience. Scientific knowledge is constructed through discussions with their peers, making use of their prior knowledge and their experiences while engaging in hands-on activities. Through the study, it is found that with the use of the Flipped Science Inquiry@CGS framework, learning experiences that are better aligned to the epistemology of science while developing 21st century competencies in students are created.

Inquiry skills are skills that aperson needs in developing concepts, but the results of the study suggest that these skills haven’t yet been trained along with the development of concepts in science feeding, found the difficulties of students in building the concept scientifically. Therefore, this study aims to find ways that are effective in training inquiry skills trough Levels of Inquiry (LoI) learning. Experimental research with one group pretest-postest design, using non-random sampling samples in one of vocational high school in Cimahi obtained purposively 33 students of X class. The research using the inquiry skills test instrument in the form of 15questions multiple choice with reliability in very high category. The result of data processing by using the normalized gain value obtained an illustration that the ways developed in the LoI are considered effective trained inquiry skills in the middle category. Some of the ways LoI learning are considered effective in communicating aspects through discovery learning, predicting trough interactive demonstration, hypotheses through inquiry lesson, and interpreting data through inquiry lab, but the implementation of LoI learning in this study hasn’t found a way that is seen as effective for trespassing aspects of designing an experiment.

Inquiry-Based Science and Technology Enrichment Program: Green Earth Enhanced with Inquiry and Technology

Science.gov (United States)

Kim, Hanna

2011-12-01

This study investigated the effectiveness of a guided inquiry integrated with technology, in terms of female middle-school students' attitudes toward science/scientists and content knowledge regarding selective science concepts (e.g., Greenhouse Effect, Air/Water Quality, Alternative Energy, and Human Health). Thirty-five female students who were entering eighth grade attended an intensive, 1-week Inquiry-Based Science and Technology Enrichment Program which used a main theme, "Green Earth Enhanced with Inquiry and Technology." We used pre- and post-attitude surveys, pre- and post-science content knowledge tests, and selective interviews to collect data and measure changes in students' attitudes and content knowledge. The study results indicated that at the post-intervention measures, participants significantly improved their attitudes toward science and science-related careers and increased their content knowledge of selected science concepts ( p < .05).

Leon Daraszkiewicz (1866-1931) was a Polish psychiatrist, a pupil and co-worker of E. Kraepelin and V. Tsiz on the University of Dorpat (now Tartu, Estonia), the author of highly regarded monograph on hebephrenia (1891). In his work on the basis of over 20 case histories, he described a natural history of hebephrenia and his own views on its aetiology and prognosis. Hebephrenia as described by Daraszkiewicz, served as a clinical model for the Kraepelinian concept of dementia praecox. In the article, the life and career of Daraszkiewicz is covered, with particular emphasis on the role of his doctoral dissertation on hebephrenia in the history of the concept of schizophrenia.

Arrangement and processing of monographic publications in youth sections of public libraries

Mateja Ločniškar-Fidler

2006-01-01

Full Text Available A systematic and transparent layout of library material on book shelves of public libraries is one of the essential conditions for successful viewing and searching of materials. The research tried to determine the contemporary classification system of library material for the youth. The data needed for the research was gathered and analyzed by a questionnaire completed by five randomly selected central public libraries. Special collections, arrangement and classification of certain fiction and specialized monographic publications for infants, teenagers and adolescents were analyzed. It was of our interest to observe whether the libraries assign the elements of a call number - which are evident on the library material and in online catalogs – according to standards and current instructions. The article also focuses on the unity and differences of the technical processing, and on color and/or image of labels which additionally explain the classification and the contents of the monographic publications for the youth.

Suitability of a liquid chromatography assay of neomycin sulfate to replace the microbiological assay for neomycin in USP Monographs.

Science.gov (United States)

Hanko, Valoran P; Rohrer, Jeffrey S

2010-01-05

The current USP National Formulary contains 65 Monographs for drug formulations containing neomycin. All 65 Monographs prescribe a bioassay for neomycin assay. This bioassay, based on cell culture, is labor intensive, has poor precision, and cannot be adapted for purity or identification. High-performance anion-exchange chromatography with integrated pulsed amperometric detection (HPAE-IPAD), a liquid chromatography technique, has been shown to be suitable for neomycin purity analysis and neomycin assay of an over-the-counter first aid cream (Hanko and Rohrer [17]). Here we propose that an HPAE-IPAD assay can replace the bioassay in the 65 neomycin-containing Monographs. We applied the HPAE-IPAD assay to four neomycin-containing drug products representing the four classes of formulations found in the 65 Monographs, liquid, solid, suspension, and cream. Each drug was analyzed with two chromatography systems, and on 3 separate days. For all products, HPAE-IPAD measurements were precise and accurate with respect to the label concentrations. There was also high accuracy for spike recovery of neomycin from the four drug products throughout 70-150% of the labeled concentration. These results suggest that an HPAE-IPAD assay would be an accurate assay for neomycin, and would be faster and more precise than the current bioassay.

Potentials in Udeskole: Inquiry-Based Teaching Outside the Classroom

Directory of Open Access Journals (Sweden)

Karen S. Barfod

2018-05-01

Full Text Available Most research on outdoor education, including the Scandinavian concept udeskole (regular curriculum-based teaching outside the classroom, has focused on pupils' outcomes, whereas less has focused on teachers' practices. In this article, we described the occurrence of inquiry-based teaching in udeskole. To analyze practice, we extended the notion of inquiry-based education. Within science and mathematics education, a strong stepwise teaching approach formerly was established, called Inquiry Based Science and Mathematics Education (IBSME, emphasizing pupils' hypothesis testing, data validation and systematic experimentation. In this study, we broadened the IBSME-concept of inquiry in order to include a more holistic, non-linear teaching approach, but excluding teacher-instructed inquiry. Using this idea, we observed and documented by field notes how five experienced teachers practiced mathematics and science teaching in udeskole at primary level in Denmark. Twenty-eight outdoor days were observed. Each day was divided into separate teaching incidents with a distinct start and end. The level of teacher interference and possible choices in each teaching incidents formed the analytic background. We analyzed each of the 71 teaching incidents, and categorized each of them into one of five categories numbered 4–0. The categories designated numbers 4–2 contained the inquiry-based teaching incidents, and the categories designated 1 and 0 were categorized as “non-inquiry-based.” They contained teaching incidents where the teacher was instructing the pupils (category 1, and outdoor teaching activities with no sign of inquiry, called training activities (category 0. Our results showed that about half of the analyzed outdoor teaching practice seemed to be inquiry-based, emphasizing pupils' choice and presenting cognitive challenge. This indicates that the analyzed udeskole had the potential to support an explorative and multifaceted inquiry

Data Sources for Trait Databases: Comparing the Phenomic Content of Monographs and Evolutionary Matrices.

Science.gov (United States)

Dececchi, T Alex; Mabee, Paula M; Blackburn, David C

2016-01-01

Databases of organismal traits that aggregate information from one or multiple sources can be leveraged for large-scale analyses in biology. Yet the differences among these data streams and how well they capture trait diversity have never been explored. We present the first analysis of the differences between phenotypes captured in free text of descriptive publications ('monographs') and those used in phylogenetic analyses ('matrices'). We focus our analysis on osteological phenotypes of the limbs of four extinct vertebrate taxa critical to our understanding of the fin-to-limb transition. We find that there is low overlap between the anatomical entities used in these two sources of phenotype data, indicating that phenotypes represented in matrices are not simply a subset of those found in monographic descriptions. Perhaps as expected, compared to characters found in matrices, phenotypes in monographs tend to emphasize descriptive and positional morphology, be somewhat more complex, and relate to fewer additional taxa. While based on a small set of focal taxa, these qualitative and quantitative data suggest that either source of phenotypes alone will result in incomplete knowledge of variation for a given taxon. As a broader community develops to use and expand databases characterizing organismal trait diversity, it is important to recognize the limitations of the data sources and develop strategies to more fully characterize variation both within species and across the tree of life.

Revising and Editing for Translators provides guidance and learning materials for translation students learning to edit texts written by others, and professional translators wishing to improve their self-revision ability or learning to revise the work of others. Editing is understood as making corrections and improvements to texts, with particular attention to tailoring them to the given readership. Revising is this same task applied to draft translations. The linguistic work of editors and revisers is related to the professional situations in which they work. Mossop offers in-depth coverage of a wide range of topics, including copyediting, style editing, structural editing, checking for consistency, revising procedures and principles, and translation quality assessment. This third edition provides extended coverage of computer aids for revisers, and of the different degrees of revision suited to different texts.

Scientists' conceptions of scientific inquiry: Revealing a private side of science

Science.gov (United States)

Reiff, Rebecca R.

Science educators, philosophers, and pre-service teachers have contributed to conceptualizing inquiry but missing from the inquiry forum is an in-depth research study concerning science faculty conceptions of scientific inquiry. The science education literature has tended to focus on certain aspects of doing, teaching, and understanding scientific inquiry without linking these concepts. As a result, conceptions of scientific inquiry have been disjointed and are seemingly unrelated. Furthermore, confusion surrounding the meaning of inquiry has been identified as a reason teachers are not using inquiry in instruction (Welch et al., 1981). Part of the confusion surrounding scientific inquiry is it has been defined differently depending on the context (Colburn, 2000; Lederman, 1998; Shymansky & Yore, 1980; Wilson & Koran, 1976). This lack of a common conception of scientific inquiry is the reason for the timely nature of this research. The result of scientific journeys is not to arrive at a stopping point or the final destination, but to refuel with questions to drive the pursuit of knowledge. A three-member research team conducted Interviews with science faculty members using a semi-structured interview protocol designed to probe the subject's conceptions of scientific inquiry. The participants represented a total of 52 science faculty members from nine science departments (anthropology, biology, chemistry, geology, geography, school of health, physical education and recreation (HPER), medical sciences, physics, and school of environmental science) at a large mid-western research university. The method of analysis used by the team was grounded theory (Strauss & Corbin, 1990; Glaser & Strauss, 1967), in which case the frequency of concepts, patterns, and themes were coded to categorize scientists' conceptions of scientific inquiry. The results from this study address the following components: understanding and doing scientific inquiry, attributes of scientists engaged

Connectivity editing for quad-dominant meshes

We propose a connectivity editing framework for quad-dominant meshes. In our framework, the user can edit the mesh connectivity to control the location, type, and number of irregular vertices (with more or fewer than four neighbors) and irregular faces (non-quads). We provide a theoretical analysis of the problem, discuss what edits are possible and impossible, and describe how to implement an editing framework that realizes all possible editing operations. In the results, we show example edits and illustrate the advantages and disadvantages of different strategies for quad-dominant mesh design. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and John Wiley & Sons Ltd.

Integration of information technology in education more rapidly performed in a medium of learning. Three-dimensional (3D) molecular modeling was performed in Augmented Reality as a tangible manifestation of increasingly modern technology utilization. Based on augmented reality, three-dimensional virtual object is projected in real time and the exact environment. This paper reviewed the uses of chemical learning supplement book of aldehydes and ketones which are equipped with three-dimensional molecular modeling by which students can inspect molecules from various viewpoints. To plays the 3D illustration printed on the book, smartphones with the open-source software of the technology based integrated Augmented Reality can be used. The aims of this research were to develop the monograph of aldehydes and ketones with 3 dimensional (3D) illustrations, to determine the specification of the monograph, and to determine the quality of the monograph. The quality of the monograph is evaluated by experiencing chemistry teachers on the five aspects of contents/materials, presentations, language and images, graphs, and software engineering, resulted in the result that the book has a very good quality to be used as a chemistry learning supplement book.

Exploring the inquiry experience: A focus on Kentucky teachers

Science.gov (United States)

Nolte, Beth

2007-12-01

Inquiry-based instruction is driven by active participation by the learner. Through the learning process, critical thinking skills are practiced. While inquiry methods are often discussed in the realm of science education, the methods are not subject specific. In fact, the Kentucky Program of Studies calls for the incorporation of inquiry strategies into all areas of the curriculum. This call for more inquiry-based education occurs in the midst of a national testing debate in which accountability is tied to student test scores. This study takes a narrative approach to explore teachers' experiences with using inquiry methods. Interviews were conducted with teachers who, at least 1 year prior to participating in this study, had attended a weeklong intensive professional development workshop on using inquiry methods for instruction. A method is described for analyzing interview data direct in its digital audio form---without transcription. Eight teachers' experiences are presented here in the narrative form and their narratives are compared for an overall analysis. Themes of conflict previously reported in the literature are explored in participants' stories. This research concludes with a discussion of the results, a reflection on the method, and suggestions for the future based on teachers' experiences with using inquiry-based learning strategies.

Teaching science as inquiry in US and in Japan: A cross-cultural comparison of science teachers' understanding of, and attitudes toward inquiry-based teaching

Science.gov (United States)

Tosa, Sachiko

Since the publication of the National Science Education Standards in 1996, learning science through inquiry has been regarded as the heart of science education. However, the TIMSS 1999 Video Study showed that inquiry-based teaching has been taking place less in the United States than in Japan. This study examined similarities and differences in how Japanese and American middle-school science teachers think and feel about inquiry-based teaching. Teachers' attitudes toward the use of inquiry in science teaching were measured through a survey instrument (N=191). Teachers' understanding of inquiry-based teaching was examined through interviews and classroom observations in the United States (N=9) and Japan (N=15). The results show that in spite of the variations in teachers' definitions of inquiry-based teaching, teachers in both countries strongly agree with the idea of inquiry-based teaching. However, little inquiry-based teaching was observed in either of the countries for different reasons. The data indicate that Japanese teachers did not generally help students construct their own understanding of scientific concepts in spite of well-planned lesson structures and activity set-ups. On the other hand, the observational data indicate that American teachers often lacked meaningful science content in spite of their high level of pedagogical knowledge. The need for addressing the importance of scientific concepts in teacher preparation programs in higher education institutions in the US is advocated. To the Japanese science education community, the need for teachers' acquisition of instructional strategies for inquiry-based teaching is strongly addressed.

Statistical Physics Approaches to RNA Editing

Science.gov (United States)

Bundschuh, Ralf

2012-02-01

The central dogma of molecular Biology states that DNA is transcribed base by base into RNA which is in turn translated into proteins. However, some organisms edit their RNA before translation by inserting, deleting, or substituting individual or short stretches of bases. In many instances the mechanisms by which an organism recognizes the positions at which to edit or by which it performs the actual editing are unknown. One model system that stands out by its very high rate of on average one out of 25 bases being edited are the Myxomycetes, a class of slime molds. In this talk we will show how the computational methods and concepts from statistical Physics can be used to analyze DNA and protein sequence data to predict editing sites in these slime molds and to guide experiments that identified previously unknown types of editing as well as the complete set of editing events in the slime mold Physarum polycephalum.

for teachers of computational stochastic methods, is the main contribution of this electronic monograph. However, both the book and software suffer from several severe problems. Firstly, I feel that the structure of the text is weak. Probably this is partly the result of the text from the CD-ROM being put into a book format, but the short paragraphs and poorly structured sentences destroy the reading experience. Secondly, although the software is functional, I believe that, like me, many users will be disappointed by the quality of the user interface and the visualizations. The opportunities to interact with the simulations are limited. Thirdly, the presentation is slightly old fashioned and lacking in pedagogical structure. For example, flow charts and Pascal programs are used to present algorithms. To conclude, I am surprised that this electronic monograph warranted a second edition in this form. Teachers may find the examples useful as a starting point, but students and researchers are advised to look elsewhere. (book review)

Payers are faced with making coverage and reimbursement decisions based on the best available evidence. Often these decisions apply to patient populations, provider networks, and care settings not typically studied in clinical trials. Treatment effectiveness evidence is increasingly available from electronic health records, registries, and administrative claims. However, little is known about when and what types of real-world evidence (RWE) studies inform pharmacy and therapeutic (P&T) committee decisions. To evaluate evidence sources cited in P&T committee monographs and therapeutic class reviews and assess the design features and quality of cited RWE studies. A convenience sample of representatives from pharmacy benefit management, health system, and health plan organizations provided recent P&T monographs and therapeutic class reviews (or references from such documents). Two investigators examined and grouped references into major categories (published studies, unpublished studies, and other/unknown) and multiple subcategories (e.g., product label, clinical trials, RWE, systematic reviews). Cited comparative RWE was reviewed to assess design features (e.g., population, data source, comparators) and quality using the Good ReseArch for Comparative Effectiveness (GRACE) Checklist. Investigators evaluated 565 references cited in 27 monographs/therapeutic class reviews from 6 managed care organizations. Therapeutic class reviews mostly cited published clinical trials (35.3%, 155/439), while single-product monographs relied most on manufacturer-supplied information (42.1%, 53/126). Published RWE comprised 4.8% (21/439) of therapeutic class review references, and none (0/126) of the monograph references. Of the 21 RWE studies, 12 were comparative and assessed patient care settings and outcomes typically not included in clinical trials (community ambulatory settings [10], long-term safety [8]). RWE studies most frequently were based on registry data (6), conducted in

Inquiry-Based Instruction and High Stakes Testing

Science.gov (United States)

Cothern, Rebecca L.

Science education is a key to economic success for a country in terms of promoting advances in national industry and technology and maximizing competitive advantage in a global marketplace. The December 2010 Program for International Student Assessment (PISA) ranked the United States 23rd of 65 countries in science. That dismal standing in science proficiency impedes the ability of American school graduates to compete in the global market place. Furthermore, the implementation of high stakes testing in science mandated by the 2007 No Child Left Behind (NCLB) Act has created an additional need for educators to find effective science pedagogy. Research has shown that inquiry-based science instruction is one of the predominant science instructional methods. Inquiry-based instruction is a multifaceted teaching method with its theoretical foundation in constructivism. A correlational survey research design was used to determine the relationship between levels of inquiry-based science instruction and student performance on a standardized state science test. A self-report survey, using a Likert-type scale, was completed by 26 fifth grade teachers. Participants' responses were analyzed and grouped as high, medium, or low level inquiry instruction. The unit of analysis for the achievement variable was the student scale score average from the state science test. Spearman's Rho correlation data showed a positive relationship between the level of inquiry-based instruction and student achievement on the state assessment. The findings can assist teachers and administrators by providing additional research on the benefits of the inquiry-based instructional method. Implications for positive social change include increases in student proficiency and decision-making skills related to science policy issues which can help make them more competitive in the global marketplace.

The perceptions of inquiry held by greater Houston area science supervisors

Science.gov (United States)

Aoki, Jon Michael

The purpose of this study was to describe the perceptions of inquiry held by responding greater Houston area science supervisors. Leading science organizations proposed that students might be better served if students are mentally and physically engaged in the process of finding out about natural phenomena rather than by didactic modes of teaching and learning. During the past fifty years, inquiry-based instruction has become a significant theme of new science programs. Students are more likely to make connections between classroom exercises and their personal lives through the use of inquiry-based instruction. Learning becomes relevant to students. Conversely, traditional science instruction often has little or no connection to students' everyday lives (Papert, 1980). In short, inquiry-based instruction empowers students to become independent thinkers. The utilization of inquiry-based instruction is essential to a successful reform in science education. However, a reform's success is partly determined by the extent to which science supervisors know and understand inquiry and consequently promote its integration in the district's science curricula. Science supervisors have the role of providing curriculum and instructional support to science teachers and for implementing science programs. There is a fundamental need to assess the perceptions of inquiry held by greater Houston area science supervisors. Science supervisor refers to a class of job titles that include department chairperson, science specialist, science consultant, and science coordinator. The target population was greater Houston area science supervisors in Texas. This study suggests that there are three major implications for educational practice. First, there is the implication that responding greater Houston area science supervisors need an inclusive perception of inquiry. Second, responding greater Houston area science supervisors' perception of inquiry may affect the perceptions and understandings

Effects of collaboration and inquiry on reasoning and achievement in biology

Science.gov (United States)

Jensen, Jamie Lee

The primary purpose of the present study was to compare the effectiveness of two collaborative grouping strategies and two instructional methods in terms of gains in reasoning ability and achievement in college biology. In order to do so, a quasi-experimental study was performed in which students were placed in one of four treatment conditions: heterogeneous grouping within inquiry instruction, homogeneous grouping within inquiry instruction, heterogeneous grouping within non-inquiry instruction, and homogeneous grouping within non-inquiry instruction. Students were placed in groups based on initial reasoning level. Reasoning levels and achievement gains were assessed at the end of the study. Results showed that within non-inquiry instruction, heterogeneous mean group scores were higher in both reasoning and achievement than homogeneous groups. In contrast, within inquiry instruction, homogeneous mean group scores were higher in both reasoning and achievement. Inquiry instruction, as a whole, significantly outperformed non-inquiry instruction in the development of reasoning ability. Within inquiry instruction, low-ability students had significantly greater reasoning gains when grouped homogeneously. These results support Piaget's developmental theory and contradict Vygotsky's developmental theory. These results also suggest that the success of one grouping strategy over another is highly dependent upon the nature of instruction, which may be a cause for such conflicting views on grouping strategies within the educational literature. In addition, inquiry instruction led to students having greater confidence in their reasoning ability as well as a more positive attitude toward collaboration. Instructional implications are discussed.

In teaching inquiry to high school students, educators differ on which method of teaching inquiry is more effective: Guided or open inquiry? This paper examines the influence of these two different inquiry learning approaches on the attitudes of Israeli high school biology students toward their inquiry project. The results showed significant differences between the two groups: Open inquiry students were more satisfied and felt they gained benefits from implementing the project to a greater extent than guided inquiry students. On the other hand, regarding documentation throughout the project, guided inquiry students believed that they conducted more documentation, as compared to their open inquiry peers. No significant differences were found regarding `the investment of time', but significant differences were found in the time invested and difficulties which arose concerning the different stages of the inquiry process: Open inquiry students believed they spent more time in the first stages of the project, while guided inquiry students believed they spent more time in writing the final paper. In addition, other differences were found: Open inquiry students felt more involved in their project, and felt a greater sense of cooperation with others, in comparison to guided inquiry students. These findings may help teachers who hesitate to teach open inquiry to implement this method of inquiry; or at least provide their students with the opportunity to be more involved in inquiry projects, and ultimately provide their students with more autonomy, high-order thinking, and a deeper understanding in performing science.

With CRISPR/Cas9 and other genome-editing technologies, successful somatic and germline genome editing are becoming feasible. To respond, an American Society of Human Genetics (ASHG) workgroup developed this position statement, which was approved by the ASHG Board in March 2017. The workgroup included representatives from the UK Association of Genetic Nurses and Counsellors, Canadian Association of Genetic Counsellors, International Genetic Epidemiology Society, and US National Society of Genetic Counselors. These groups, as well as the American Society for Reproductive Medicine, Asia Pacific Society of Human Genetics, British Society for Genetic Medicine, Human Genetics Society of Australasia, Professional Society of Genetic Counselors in Asia, and Southern African Society for Human Genetics, endorsed the final statement. The statement includes the following positions. (1) At this time, given the nature and number of unanswered scientific, ethical, and policy questions, it is inappropriate to perform germline gene editing that culminates in human pregnancy. (2) Currently, there is no reason to prohibit in vitro germline genome editing on human embryos and gametes, with appropriate oversight and consent from donors, to facilitate research on the possible future clinical applications of gene editing. There should be no prohibition on making public funds available to support this research. (3) Future clinical application of human germline genome editing should not proceed unless, at a minimum, there is (a) a compelling medical rationale, (b) an evidence base that supports its clinical use, (c) an ethical justification, and (d) a transparent public process to solicit and incorporate stakeholder input.

Connectivity editing for quadrilateral meshes

KAUST Repository

Peng, Chihan

2011-12-12

We propose new connectivity editing operations for quadrilateral meshes with the unique ability to explicitly control the location, orientation, type, and number of the irregular vertices (valence not equal to four) in the mesh while preserving sharp edges. We provide theoretical analysis on what editing operations are possible and impossible and introduce three fundamental operations to move and re-orient a pair of irregular vertices. We argue that our editing operations are fundamental, because they only change the quad mesh in the smallest possible region and involve the fewest irregular vertices (i.e., two). The irregular vertex movement operations are supplemented by operations for the splitting, merging, canceling, and aligning of irregular vertices. We explain how the proposed highlevel operations are realized through graph-level editing operations such as quad collapses, edge flips, and edge splits. The utility of these mesh editing operations are demonstrated by improving the connectivity of quad meshes generated from state-of-art quadrangulation techniques. © 2011 ACM.

Zhu, Linjiang; Li, Qi

2015-03-01

Genome editing is defined as highly-effective and precise modification of cellular genome in a large scale. In recent years, such genome-editing methods have been rapidly developed in the field of industrial strain improvement. The quickly-updating methods thoroughly change the old mode of inefficient genetic modification, which is "one modification, one selection marker, and one target site". Highly-effective modification mode in genome editing have been developed including simultaneous modification of multiplex genes, highly-effective insertion, replacement, and deletion of target genes in the genome scale, cut-paste of a large DNA fragment. These new tools for microbial genome editing will certainly be applied widely, and increase the efficiency of industrial strain improvement, and promote the revolution of traditional fermentation industry and rapid development of novel industrial biotechnology like production of biofuel and biomaterial. The technological principle of these genome-editing methods and their applications were summarized in this review, which can benefit engineering and construction of industrial microorganism.

Sustaining inquiry-based teaching methods in the middle school science classroom

Science.gov (United States)

Murphy, Amy Fowler

This dissertation used a combination of case study and phenomenological research methods to investigate how individual teachers of middle school science in the Alabama Math, Science, and Technology Initiative (AMSTI) program sustain their use of inquiry-based methods of teaching and learning. While the overall context for the cases was the AMSTI program, each of the four teacher participants in this study had a unique, individual context as well. The researcher collected data through a series of interviews, multiple-day observations, and curricular materials. The interview data was analyzed to develop a textural, structural, and composite description of the phenomenon. The Reformed Teaching Observation Protocol (RTOP) was used along with the Assesing Inquiry Potential (AIP) questionnaire to determine the level of inquiry-based instruction occuring in the participants classrooms. Analysis of the RTOP data and AIP data indicated all of the participants utilized inquiry-based methods in their classrooms during their observed lessons. The AIP data also indicated the level of inquiry in the AMSTI curricular materials utilized by the participants during the observations was structured inquiry. The findings from the interview data suggested the ability of the participants to sustain their use of structured inquiry was influenced by their experiences with, beliefs about, and understandings of inquiry. This study contributed to the literature by supporting existing studies regarding the influence of teachers' experiences, beliefs, and understandings of inquiry on their classroom practices. The inquiry approach stressed in current reforms in science education targets content knowledge, skills, and processes needed in a future scientifically literate citizenry.

The influence of democratic racism in nursing inquiry.

Hilario, Carla T; Browne, Annette J; McFadden, Alysha

2018-01-01

Neoliberal ideology and exclusionary policies based on racialized identities characterize the current contexts in North America and Western Europe. Nursing knowledge cannot be abstracted from social, political and historical contexts; the task of examining the influence of race and racial ideologies on disciplinary knowledge and inquiry therefore remains an important task. Contemporary analyses of the role and responsibility of the discipline in addressing race-based health and social inequities as a focus of nursing inquiry remain underdeveloped. In this article, we examine nursing's engagement with ideas about race and racism and explore the ways in which nursing knowledge and inquiry have been influenced by race-based ideological discourses. Drawing on Henry and Tator's framework of democratic racism, we consider how strategic discursive responses-the discourses of individualism, multiculturalism, colour-blindness, political correctness and denial-have been deployed within nursing knowledge and inquiry to reinforce the belief in an essentially fair and just society while avoiding the need to acknowledge the persistence of racist discourses and ideologies. Greater theoretical, conceptual and methodological clarity regarding race, racialization and related concepts in nursing inquiry is needed to address health and social inequities. © 2017 John Wiley & Sons Ltd.

Deletions in cox2 mRNA result in loss of splicing and RNA editing and gain of novel RNA editing sites.

Directory of Open Access Journals (Sweden)

Stefanie Grüttner

Full Text Available As previously demonstrated, the maize cox2 RNA is fully edited in cauliflower mitochondria. Use of constructs with a deleted cox2 intron, however, led to a loss of RNA editing at almost all editing sites, with only a few sites still partially edited. Likewise, one deletion in exon 1 and three in exon 2 abolish RNA editing at all cox2 sites analyzed. Furthermore, intron splicing is abolished using these deletions. Mutation of a cytosine residue, which is normally edited and localized directly adjacent to the intron, to thymidine did not result in restoration of splicing, indicating that the loss of splicing was not due to loss of RNA editing. One deletion in exon 2 did not lead to loss of splicing. Instead, most editing sites were found to be edited, only three were not edited. Unexpectedly, we observed additional RNA editing events at new sites. Thus it appears that deletions in the cox2 RNA sequence can have a strong effect on RNA processing, leading to loss of splicing, loss of editing at all sites, or even to a gain of new editing sites. As these effects are not limited to the vicinity of the respective deletions, but appear to be widespread or even affect all editing sites, they may not be explained by the loss of PPR binding sites. Instead, it appears that several parts of the cox2 transcript are required for proper RNA processing. This indicates the roles of the RNA sequence and structural elements in the recognition of the editing sites.

Using Peer Feedback to Improve Students' Scientific Inquiry

Tasker, Tammy Q.; Herrenkohl, Leslie Rupert

2016-02-01

This article examines a 7th grade teacher's pedagogical practices to support her students to provide peer feedback to one another using technology during scientific inquiry. This research is part of a larger study in which teachers in California and Washington and their classes engaged in inquiry projects using a Web-based system called Web of Inquiry. Videotapes of classroom lessons and artifacts such as student work were collected as part of the corpus of data. In the case examined, Ms. E supports her students to collectively define "meaningful feedback," thereby improving the quality of feedback that was provided in the future. This is especially timely, given the attention in Next Generation Science Standards to cross-cutting concepts and practices that require students discuss and debate ideas with each other in order to improve their understanding and their written inquiry reports (NGSS, 2013).

This monograph is a companion to UNOAI Monograph 96-2, "The Image of Airport Security: An Annotated Bibliography," compiled in June 1996. The White House Commission on Aviation Safety and Security, headed by Vice President Al Gore, was formed as a result of the TWA Flight 800 crash in August 1996. The Commission's final report included 31 recommendations addressed toward aviation security. The recommendations were cause for security issues to be revisited in the media and by the aviation industry. These developments necessitated the need for an updated bibliography to review the resulting literature. Many of the articles were written in response to the recommendations made by the Gore Commission. "Aviation Security: An Annotated Bibliography of Responses to the Gore Commission" is the result of this need.

2013-01-01

Full Text Available RNA editing is vital to provide the RNA and protein complexity to regulate the gene expression. Correct RNA editing maintains the cell function and organism development. Imbalance of the RNA editing machinery may lead to diseases and cancers. Recently, RNA editing has been recognized as a target for drug discovery although few studies targeting RNA editing for disease and cancer therapy were reported in the field of natural products. Therefore, RNA editing may be a potential target for therapeutic natural products. In this review, we provide a literature overview of the biological functions of RNA editing on gene expression, diseases, cancers, and drugs. The bioinformatics resources of RNA editing were also summarized.

Kindergarten Teachers' Understanding of the Elements of Implementing Inquiry-Based Science Instruction

Science.gov (United States)

Blevins, Kathryn

The purpose of this basic qualitative research study was to identify the extent to which kindergarten teachers understand and implement inquiry-based instruction in their science classrooms. This study was conducted in response to the indication that traditional didactic teaching methods were not enough to adequately prepare American students to compete in the global economy. Inquiry is a teaching method that could prepare students for the critical thinking skills needed to enter society in the 21st century. It is vital that teachers be sufficiently trained in teaching using the necessary components of inquiry-based instruction. This study could be used to inform leaders in educational administration of the gaps in teachers' understanding as it pertains to inquiry, thus allowing for the delivery of professional development that will address teachers' needs. Existing literature on inquiry-based instruction provides minimal information on kindergarten teachers' understanding and usage of inquiry to teach science content, and this information would be necessary to inform administrators in their response to supporting teachers in the implementation of inquiry. The primary research question for this study was "To what extent do kindergarten teachers understand the elements of implementing inquiry-based lessons in science instruction?" The 10 participants in this study were all kindergarten teachers in a midsized school district in the Mid-Atlantic region of the United States. Data were collected using face-to-face semistructured interviews, observations of the teachers implementing what they perceived to be inquiry-based instruction, and the analysis of lesson plans to indicate the components used to plan for inquiry-instruction. The findings of this study indicated that while teachers believed inquiry to be a beneficial method for teaching science, they did not understand the components of inquiry and tended to implement lesson plans created at the district level.

An investigation of children's levels of inquiry in an informal science setting

Science.gov (United States)

Clark-Thomas, Beth Anne

Elementary school students' understanding of both science content and processes are enhanced by the higher level thinking associated with inquiry-based science investigations. Informal science setting personnel, elementary school teachers, and curriculum specialists charged with designing inquiry-based investigations would be well served by an understanding of the varying influence of certain present factors upon the students' willingness and ability to delve into such higher level inquiries. This study examined young children's use of inquiry-based materials and factors which may influence the level of inquiry they engaged in during informal science activities. An informal science setting was selected as the context for the examination of student inquiry behaviors because of the rich inquiry-based environment present at the site and the benefits previously noted in the research regarding the impact of informal science settings upon the construction of knowledge in science. The study revealed several patterns of behavior among children when they are engaged in inquiry-based activities at informal science exhibits. These repeated behaviors varied in the children's apparent purposeful use of the materials at the exhibits. These levels of inquiry behavior were taxonomically defined as high/medium/low within this study utilizing a researcher-developed tool. Furthermore, in this study adult interventions, questions, or prompting were found to impact the level of inquiry engaged in by the children. This study revealed that higher levels of inquiry were preceded by task directed and physical feature prompts. Moreover, the levels of inquiry behaviors were haltered, even lowered, when preceded by a prompt that focused on a science content or concept question. Results of this study have implications for the enhancement of inquiry-based science activities in elementary schools as well as in informal science settings. These findings have significance for all science educators

Refining Inquiry with Multi-Form Assessment: Formative and summative assessment functions for flexible inquiry

Science.gov (United States)

Zuiker, Steven; Reid Whitaker, J.

2014-04-01

This paper describes the 5E+I/A inquiry model and reports a case study of one curricular enactment by a US fifth-grade classroom. A literature review establishes the model's conceptual adequacy with respect to longstanding research related to both the 5E inquiry model and multiple, incremental innovations of it. As a collective line of research, the review highlights a common emphasis on formative assessment, at times coupled either with differentiated instruction strategies or with activities that target the generalization of learning. The 5E+I/A model contributes a multi-level assessment strategy that balances formative and summative functions of multiple forms of assessment in order to support classroom participation while still attending to individual achievement. The case report documents the enactment of a weeklong 5E+I/A curricular design as a preliminary account of the model's empirical adequacy. A descriptive and analytical narrative illustrates variable ways that multi-level assessment makes student thinking visible and pedagogical decision-making more powerful. In light of both, it also documents productive adaptations to a flexible curricular design and considers future research to advance this collective line of inquiry.

The Sizewell inquiry - is there a better way

International Nuclear Information System (INIS)

Greenhalgh, G.

1984-01-01

The author sees the Inquiry as the latest in a line arising from government's wish to achieve greater public participation in controversial decisions. He believes that the Sizewell Inquiry is unlikely to shake the public out of its apathy, while a decision that goes against them will not satisfy the objectors. The concept of the Inquiry is based on the belief that the legal process will unearth objective truth, while most of the issues are matters of opinion and judgement. The wide-ranging terms of reference are leading to constitutional anomalies and attempts to take on Herculean tasks in the search for objective truth. However, while concluding that an Inquiry Commission adopting a legal approach and following courtroom procedures is not a satisfactory way of dealing with large-scale technological projects, the author finds it hard to suggest alternatives short of more direct parliamentary control.

Clandinin, D Jean; Cave, Marie T; Berendonk, Charlotte

2017-01-01

Narrative research, an inclusive term for a range of methodologies, has rapidly become part of medical education scholarship. In this paper we identify narrative inquiry as a particular theoretical and methodological framework within narrative research and outline its characteristics. We briefly summarise how narrative research has been used in studying medical learners' identity making in medical education. We then turn to the uses of narrative inquiry in studying medical learners' professional identity making. With the turn to narrative inquiry, the shift is to thinking with stories instead of about stories. We highlight four challenges in engaging in narrative inquiry in medical education and point toward promising future research and practice possibilities. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Tabulation and classification of drugs and dietary supplement inquiries. Characteristics and trends of drug and dietary supplement inquiries. Inquiries for prescription medications for albuterol inhalers, methylphenidate, amphetamines, and prednisone were the most common using a drug lookup function. The most common inquiries for over-the-counter medications included pseudoephedrine, loratadine, cetirizine, and caffeine. Among dietary supplements, inquiries for amino acids/metabolites, vitamins and minerals, and herbal products occurred most frequently. One dietary supplement, N.O.-Xplode (Bio-Engineered Supplements and Nutrition, Inc.), accounted for the majority of individual dietary supplement inquiries. Banned substances accounted for 30% of all inquiries submitted to the REC and 18% of medications searched in a drug lookup database. Almost 25,000 inquiries were submitted to the REC. Pharmacists can use this information to advise, counsel, and refer NCAA athletes regarding the use of banned and permitted substances. Education programs regarding stimulants, dietary supplements, and the risk of using substances such as animal byproducts are needed, and pharmacists can participate in these programs.

The nuclear inquiry

International Nuclear Information System (INIS)

Clement, K.J.

1987-01-01

Opposition to nuclear energy facilities has increased considerably in Scotland and Germany within the past two decades. The statutory institutions which exist in each country to consider formal objections to such developments have important differences, as do the licensing or planning processes of which they form an integral part. In Britain, the initiation of judicial review following public inquiries is very rare, due to the limited grounds within which this would be possible. By contrast, there has been a very high referral of nuclear power station decisions to the administrative courts in Germany, but the number is now declining as cases are invariably found in favour of the developers. The comparative examination of case studies reveals that objectors' interests may best be served, in terms of achieving policy influence, by acting outside the restrictions of the statutory planning and legal systems. The Scottish public inquiry is revealed as the more flexible institution and one which allows a much greater degree of public participation. (author)

The contribution of formative assessment and self-efficacy to inquiry learning

Dolin, Jens; Evans, Robert Harry

2013-01-01

This chapter suggests the use of formative assessment in inquiry lessons as a helpful source of positive personal capacity beliefs for both teachers and students. The challenge most commonly experienced when first using inquiry learning methods is that pupils and even teachers become uncertain...... of their abilities to use inquiry and ‘give-up’ on it. With the use of formative assessment combined with conscious efforts to increase self-efficacy among students, teachers can help provide students with the confidence and motivation to engage in inquiry methods. Such student engagement can in-turn affirm teachers......’ inquiry teaching efforts and raise the likelihood that they will continue to improve them. We see inquiry methods as the motor for changing teacher practice and formative assessment methods combined with capacity beliefs as the fuel that keeps the motor running. The central position of the chapter is how...

1998-10-01

The first edition of John Wesson's book on tokamaks, published in 1987, established itself as essential reading for researchers in the field of magnetic confinement fusion: it was an excellent introduction for students to tokamak physics and also a valuable reference work for the more experienced. The second edition, published in 1997, has been completely rewritten and substantially enlarged (680 pages compared with 300). The new edition maintains the aim of providing a simple introduction to basic tokamak physics, but also includes discussion of the substantial advances in fusion research during the past decade. The new book, like its predecessor, is well written and commendable for its clarity and accuracy. In fact many of the chapters are written by a series of co-authors bringing the benefits of a wide range of expertise but, by careful editing, Wesson has maintained a uniformity of style and presentation. The chapter headings and coverage for the most part remain the same - but are expanded considerably and brought up to date. The most substantial change is that the single concluding chapter in the first edition on 'Experiments' has been replaced by three chapters: 'Tokamak experiments' which deals with some of the earlier key experiments plus a selection of recent small and medium-sized devices, 'Large experiments' which gives an excellent summary of the main results from the four large tokamaks - TFTR, JET, JT60/JT60U and DIII-D, and 'The future' which gives a very short (possibly too short in my opinion) account of reactors and ITER. This is an excellent book, which I strongly recommend should have a place - on the desk rather than in the bookshelf - of researchers in magnetic confinement fusion. (book review)

The new book, like its predecessor, is well written and commendable for its clarity and accuracy. In fact many of the chapters are written by a series of co-authors bringing the benefits of a wide range of expertise but, by careful editing, Wesson has maintained a uniformity of style and presentation. The chapter headings and coverage for the most part remain the same - but are expanded considerably and brought up to date. The most substantial change is that the single concluding chapter in the first edition on 'Experiments' has been replaced by three chapters: 'Tokamak experiments' which deals with some of the earlier key experiments plus a selection of recent small and medium-sized devices, 'Large experiments' which gives an excellent summary of the main results from the four large tokamaks - TFTR, JET, JT60/JT60U and DIII-D, and 'The future' which gives a very short (possibly too short in my opinion) account of reactors and ITER. This is an excellent book, which I strongly recommend should have a place - on the desk rather than in the bookshelf - of researchers in magnetic confinement fusion. (book review)

Preservice science teachers' experiences with repeated, guided inquiry

Science.gov (United States)

Slack, Amy B.

The purpose of this study was to examine preservice science teachers' experiences with repeated scientific inquiry (SI) activities. The National Science Education Standards (National Research Council, 1996) stress students should understand and possess the abilities to do SI. For students to meet these standards, science teachers must understand and be able to perform SI; however, previous research demonstrated that many teachers have naive understandings in this area. Teacher preparation programs provide an opportunity to facilitate the development of inquiry understandings and abilities. In this study, preservice science teachers had experiences with two inquiry activities that were repeated three times each. The research questions for this study were (a) How do preservice science teachers' describe their experiences with repeated, guided inquiry activities? (b) What are preservice science teachers' understandings and abilities of SI? This study was conducted at a large, urban university in the southeastern United States. The 5 participants had bachelor's degrees in science and were enrolled in a graduate science education methods course. The researcher was one of the course instructors but did not lead the activities. Case study methodology was used. Data was collected from a demographic survey, an open-ended questionnaire with follow-up interviews, the researcher's observations, participants' lab notes, personal interviews, and participants' journals. Data were coded and analyzed through chronological data matrices to identify patterns in participants' experiences. The five domains identified in this study were understandings of SI, abilities to conduct SI, personal feelings about the experience, science content knowledge, and classroom implications. Through analysis of themes identified within each domain, the four conclusions made about these preservice teachers' experiences with SI were that the experience increased their abilities to conduct inquiry

Adenosine-to-inosine (A-to-I) RNA editing, catalysed by ADAR enzymes conserved in metazoans, plays an important role in neurological functions. Although the fine-tuning mechanism provided by A-to-I RNA editing is important, the underlying rules governing ADAR substrate recognition are not well understood. We apply a quantitative trait loci (QTL) mapping approach to identify genetic variants associated with variability in RNA editing. With very accurate measurement of RNA editing levels at 789 sites in 131 Drosophila melanogaster strains, here we identify 545 editing QTLs (edQTLs) associated with differences in RNA editing. We demonstrate that many edQTLs can act through changes in the local secondary structure for edited dsRNAs. Furthermore, we find that edQTLs located outside of the edited dsRNA duplex are enriched in secondary structure, suggesting that distal dsRNA structure beyond the editing site duplex affects RNA editing efficiency. Our work will facilitate the understanding of the cis-regulatory code of RNA editing.

Prioritizing Chemicals for Risk Assessment Using Chemoinformatics: Examples from the IARC Monographs on Pesticides.

2016-12-01

Identifying cancer hazards is the first step towards cancer prevention. The International Agency for Research on Cancer (IARC) Monographs Programme, which has evaluated nearly 1,000 agents for their carcinogenic potential since 1971, typically selects agents for hazard identification on the basis of public nominations, expert advice, published data on carcinogenicity, and public health importance. Here, we present a novel and complementary strategy for identifying agents for hazard evaluation using chemoinformatics, database integration, and automated text mining. To inform selection among a broad range of pesticides nominated for evaluation, we identified and screened nearly 6,000 relevant chemical structures, after which we systematically compiled information on 980 pesticides, creating network maps that allowed cluster visualization by chemical similarity, pesticide class, and publicly available information concerning cancer epidemiology, cancer bioassays, and carcinogenic mechanisms. For the IARC Monograph meetings that took place in March and June 2015, this approach supported high-priority evaluation of glyphosate, malathion, parathion, tetrachlorvinphos, diazinon, p,p'-dichlorodiphenyltrichloroethane (DDT), lindane, and 2,4-dichlorophenoxyacetic acid (2,4-D). This systematic approach, accounting for chemical similarity and overlaying multiple data sources, can be used by risk assessors as well as by researchers to systematize, inform, and increase efficiency in selecting and prioritizing agents for hazard identification, risk assessment, regulation, or further investigation. This approach could be extended to an array of outcomes and agents, including occupational carcinogens, drugs, and foods. Citation: Guha N, Guyton KZ, Loomis D, Barupal DK. 2016.

Comparing the perceptions of scientific inquiry between experts and practitioners

Science.gov (United States)

Gooding, Julia Terese Chembars

The purpose of this study was to determine if there was a difference in the perception of scientific inquiry between experts and practitioners, and, if a difference was shown to exist, to analyze those perceptions in order to better understand the extent of that difference or gap. A disconnect was found between how experts and practitioners perceived scientific inquiry. The practitioners differed from both the experts and the literature in three key areas. First, although the teachers indicated that students would be manipulating materials, there was no direct reference to this manipulation actually being performed for the purpose of investigating. Second, the practitioners implied active physical engagement with materials, but they did not tie this to active mental engagement or direct involvement in their own learning. Third, teachers omitted their role in laying the foundation for inquiry. Though classroom teachers lacked a complete understanding of true inquiry and its place in the K-12 classroom, most of them actually believed they were practicing the art of teaching via inquiry. Additionally, two other points of interest arose. First, an examination of the national standards for a number of curricular areas established that the process skills of scientific inquiry are mirrored in those standards, implying that inquiry is not limited to the sciences. Second, a definition of inquiry was formulated based upon interviews with experts in the field. Although the literature and the experts were in unison in their definition, there was a disparity between the accepted definition and that provided by the teachers. The struggle for a comprehensive understanding of inquiry continues to this day. It might very well be that the concept still remains elusive partly because the teacher behaviors associated with it run counter to more traditional methods of instruction...methods that most teachers have experienced throughout their own educational careers. The most pervasive

To characterize pregnancy and lactation-related medication inquiries to a drug information center to identify classes of medications of most concern to providers. A secondary objective was to identify any trends in provider inquiries over the study period. A retrospective descriptive study of pregnancy and lactation-related inquiries to the University of North Carolina Health Care System Drug Information Center database between January 2001 and December 2010. University of North Carolina Health Care System Drug Information Center. Provider inquiries and responses were extracted and characterized by indication for treatment and reason for inquiry. Comparison of the first and second 5-year periods was performed to delineate trends. Descriptive statistics, Fisher's Exact and χ2 tests were used for analysis. Inquiry origin, time, and subject. 433 inquiries were retrieved over the study period from physicians (50%), pharmacists (21%), and nurses (18%). Inquiries were most often made during the antepartum period (34%), followed by the postpartum (28%) and preconception (22%) periods. The most frequent indications for inquiry were psychiatry (15%) and infectious diseases (14%), which remained constant throughout the study period. Safety was the most common reason for inquiry (52%). The responses provided to callers were limited due to lack of information availability 37% of the time. Psychiatry and infectious disease-related indications are the most frequent subjects of provider inquiry regarding medication use in pregnancy. Rates of inquiry remained constant throughout the past decade in most therapeutic areas. These findings are consistent with previous observations in other developed countries and suggest high-yield areas for pharmacist education.

"Martian Boneyards": Sustained Scientific Inquiry in a Social Digital Game

Science.gov (United States)

Asbell-Clarke, Jordis

Social digital gaming is an explosive phenomenon where youth and adults are engaged in inquiry for the sake of fun. The complexity of learning evidenced in social digital games is attracting the attention of educators. Martian Boneyards is a proof-of-concept game designed to study how a community of voluntary gamers can be enticed to engage in sustained, high-quality scientific inquiry. Science educators and game designers worked together to create an educational game with the polish and intrigue of a professional-level game, striving to attract a new audience to scientific inquiry. Martian Boneyards took place in the high-definition, massively multiplayer online environment, Blue Mars, where players spent an average of 30 hours in the game over the 4-month implementation period, with some exceeding 200 hours. Most of the players' time was spent in scientific inquiry activities and about 30% of the players' in-game interactions were in the analysis and theory-building phases of inquiry. Female players conducted most of the inquiry, in particular analysis and theory building. The quality of scientific inquiry processes, which included extensive information gathering by players, and the resulting content were judged to be very good by a team of independent scientists. This research suggests that a compelling storyline, a highly aesthetic environment, and the emergent social bonds among players and between players and the characters played by designers were all responsible for sustaining high quality inquiry among gamers in this free-choice experience. The gaming environment developed for Martian Boneyards is seen as an evolving ecosystem with interactions among design, players' activity, and players' progress.

Democracy and the Sizewell inquiry

International Nuclear Information System (INIS)

Armstrong, J.

1987-01-01

In this paper the brief summary of selected procedural aspects of the Sizewell Inquiry indicates that the way in which major and controversial planning proposals are subject to public debate is in need of urgent review. The Sizewell Inquiry fell short of public expectation, and indeed of Government promises, on two major counts; it did not provide a forum for the debate of certain questions which are clearly of utmost importance and concern to the nuclear issue, while its semi-judicial format and unbalanced funding effectively discouraged and often prevented the level of participation which many objecting parties sought. The Government's assurance of a 'full and fair' debate proved to be hollow and in some quarters this has served to increase scepticism of the stated desire for public involvement in nuclear decision-making. Of the major controversies which have been in the subject of public inquiries in recent years, nuclear power is clearly one of the most challenging. It brings together an extremely varied band of objectors which, in the light of recent radioactive leakages from Windscale, future plans for waste storage facilities and the proposed plutonium reprocessing plant at Dounreay, promises only to grow

NTP Monograph: Developmental Effects and Pregnancy Outcomes Associated With Cancer Chemotherapy Use During Pregnancy.

Science.gov (United States)

2013-05-01

The National Toxicology Program (NTP) Office of Health Assessment and Translation (OHAT) conducted an evaluation of the developmental effects and pregnancy outcomes associated with cancer chemotherapy use during pregnancy in humans. The final NTP monograph was completed in May 2013 (available at http:// ntp.niehs.nih.gov/go/36495). The incidence of cancer during pregnancy has been reported to occur from 17 to 100 per 100,000 pregnant women. Chemotherapy is a common treatment for cancer; however, most chemotherapy agents are classified as known or suspected human teratogens. Cancer chemotherapy use during pregnancy was selected for evaluation by the NTP because of the: (1) paucity of comprehensive reviews on the pregnancy outcomes following cancer chemotherapy use during pregnancy in humans, including the integration of the developmental animal toxicology literature with the observational studies in humans, and (2) growing public interest in the developmental effects of chemotherapy on offspring exposed to cancer chemotherapy during gestation due to the expected incidence of cancer diagnosed during pregnancy as women delay pregnancy to later ages. Of the approximately 110 cancer chemotherapeutic agents currently in use, the NTP monograph includes data on 56 agents used during 1,261 pregnancies for which pregnancy outcomes were documented. Overall, the NTP evaluation found that treatment with chemotherapy for cancer appeared to be associated with: (1) a higher rate of major malformations following exposure during the first trimester compared to exposure in the second and/or third trimester; (2) an increase the rate of stillbirth following exposure in the second and/ or third trimester; abnormally low levels of amniotic fluid (primarily attributable to Trastuzumab); and (3), also data are insufficient, impaired fetal growth and myelosuppression. Treatment with chemotherapy for cancer during pregnancy did not appear to increase spontaneous preterm birth, or impair

Editing Audio with Audacity

Full Text Available For those interested in audio, basic sound editing skills go a long way. Being able to handle and manipulate the materials can help you take control of your object of study: you can zoom in and extract particular moments to analyze, process the audio, and upload the materials to a server to compliment a blog post on the topic. On a more practical level, these skills could also allow you to record and package recordings of yourself or others for distribution. That guest lecture taking place in your department? Record it and edit it yourself! Doing so is a lightweight way to distribute resources among various institutions, and it also helps make the materials more accessible for readers and listeners with a wide variety of learning needs. In this lesson you will learn how to use Audacity to load, record, edit, mix, and export audio files. Sound editing platforms are often expensive and offer extensive capabilities that can be overwhelming to the first-time user, but Audacity is a free and open source alternative that offers powerful capabilities for sound editing with a low barrier for entry. For this lesson we will work with two audio files: a recording of Bach’s Goldberg Variations available from MusOpen and another recording of your own voice that will be made in the course of the lesson. This tutorial uses Audacity 2.1.2, released January 2016.

Mapping Science in Discourse-based Inquiry Classrooms

Science.gov (United States)

Yeneayhu, Demeke Gesesse

Abstract The purpose of this study was to investigate how discourse-based inquiry science lessons provided opportunities for students to develop a network of semantic relations among core ideas and concepts in science. It was a naturalistic inquiry classroom lessons observation study on three science teachers--- a middle school science teacher and two high school physics teachers in an urban school district located in the Western New York region. Discourse and thematic analysis drawn from the theory of Systemic Functional Linguistics were utilized as guiding framework and analysis tools. Analysis of the pre-observation and post-observation interviews of the participant teachers revealed that all of the three teachers participated in at least one inquiry-based science teaching teacher professional development program and they all thought their classroom teaching practice was inquiry-based. Analysis of their classroom lesson videos that each participant teacher taught on a specific science topic revealed that the middle school teacher was found to be a traditional teacher-dominated classroom whereas the two high school physics teachers' classroom teaching approach was found to be discourse-based inquiry. One of the physics teachers who taught on a topic of Magnetic Interaction used relatively structured and guided-inquiry classroom investigations. The other physics teacher who taught on a topic of Color Mixing utilized open-ended classroom investigations where the students planned and executed the series of classroom science investigations with minimal guidance from the teacher. The traditional teacher-based classroom communicative pattern was found to be dominated by Triadic Dialogue and most of the science thematics were jointly developed by the teacher and the students, but the students' role was limited to providing responses to the teacher's series questions. In the guided-inquiry classroom, the common communicative pattern was found to be True Dialogue and most

Students' attitude-related responses to inquiry learning in undergraduate kinesiology laboratory instruction

Science.gov (United States)

Henige, Kimberly Ann

The purpose of this investigation was to determine whether the student attitudes are impacted when teaching methods in an undergraduate Kinesiology lab course shift from a traditional, cookbook-style, low inquiry-level to an investigative, high inquiry-level approach. Students participated in five weeks of Level 0-1 (low) inquiry activities, followed by five weeks of a Level 3 (high) inquiry project. The same Likert-scale survey was administered to students before and after each 5-week period. The attitudes measured by the survey included students' (a) attitude to scientific inquiry, (b) adoption of scientific attitudes, (c) enjoyment of science lessons, and (d) motivation in science. Repeated measures ANOVAs revealed no significant change in any of the attitude measures when the survey results from the different time points were compared. An open-ended qualitative survey was given to the students at the end of the semester and provided more insight. When asked to compare the low and high-level inquiry experiences, most students reported enjoying the higher level of inquiry more. On the other hand, most students felt they learned more during the low inquiry-level activities. The reported level of motivation in lab was about the same for both levels. When asked what they liked most about the high-level inquiry project, students favored aspects such as the independence, responsibility, and personal relevance. When asked what they liked the least, most students said there was nothing they disliked. Of the minority of students who did not like the high-level of inquiry, most claimed to be uncomfortable with the lack of structure and guidance. Other findings were that many students expressed a new or increased respect and appreciation for what scientists do. Some students experienced a decrease in their reliance on science to be true and correct. While some students thought the high-level inquiry was harder, others perceived it as being easier. These findings illustrate

Direct Visual Editing of Node Attributes in Graphs

Directory of Open Access Journals (Sweden)

Christian Eichner

2016-10-01

Full Text Available There are many expressive visualization techniques for analyzing graphs. Yet, there is only little research on how existing visual representations can be employed to support data editing. An increasingly relevant task when working with graphs is the editing of node attributes. We propose an integrated visualize-and-edit approach to editing attribute values via direct interaction with the visual representation. The visualize part is based on node-link diagrams paired with attribute-dependent layouts. The edit part is as easy as moving nodes via drag-and-drop gestures. We present dedicated interaction techniques for editing quantitative as well as qualitative attribute data values. The benefit of our novel integrated approach is that one can directly edit the data while the visualization constantly provides feedback on the implications of the data modifications. Preliminary user feedback indicates that our integrated approach can be a useful complement to standard non-visual editing via external tools.

Editing modifies the GABA(A) receptor subunit alpha3

2007-01-01

Adenosine to inosine (A-to-I) pre-mRNA editing by the ADAR enzyme family has the potential to increase the variety of the proteome. This editing by adenosine deamination is essential in mammals for a functional brain. To detect novel substrates for A-to-I editing we have used an experimental method...... to find selectively edited sites and combined it with bioinformatic techniques that find stem-loop structures suitable for editing. We present here the first verified editing candidate detected by this screening procedure. We show that Gabra-3, which codes for the alpha3 subunit of the GABA(A) receptor......, is a substrate for editing by both ADAR1 and ADAR2. Editing of the Gabra-3 mRNA recodes an isoleucine to a methionine. The extent of editing is low at birth but increases with age, reaching close to 100% in the adult brain. We therefore propose that editing of the Gabra-3 mRNA is important for normal brain...

Relativistic many-body bound systems. Monograph report

International Nuclear Information System (INIS)

Danos, M.; Gillet, V.

1975-04-01

The principles and the mathematical details of a fully relativistic nuclear theory are given. Since the concept of nuclear forces is a strictly non-relativistic construct, it must be abandoned, and the forces must be replaced explicitly by their physical origin, i.e., by the interaction between nucleons and mesons. Thus, in this monograph the description of a nucleus has been formulated as a problem of relativistic quantum field theory which is solved by nuclear physics methods; to wit: the physics is described by specifying a Lagrangian which is a functional of the constituent fields (= of the parton fields); the solutions for the physical systems then are obtained in a time-independent treatment as expansions in the parton fields: both particles and nuclei are composite systems, made up of parton configurations, which define a representation of the Hamiltonian (associated with the specified Lagrangian)

2012-03-01

Teacher education programs have adopted preparing science teachers that teach science through inquiry as an important pedagogic agenda. However, their efforts have not met with much success. While traditional explanations for this failure focus largely on preservice science teachers' knowledge, beliefs and conceptions regarding science and science teaching, this conceptual paper seeks to direct attention toward discursive practices surrounding inquiry science teaching in teacher education programs for understanding why most science teachers do not teach science through inquiry. The paper offers a theoretical framework centered on critical notions of subjection and performativity as a much needed perspective on making/becoming of science teachers through participation in discursive practices of science teacher education programs. It argues that research based on such perspectives have much potential to offer a deeper understanding of the difficult challenges teacher education programs face in preparing inquiry practicing science teachers.

Evidence regarding carcinogenic mechanisms serves a critical role in International Agency for Research on Cancer (IARC) Monograph evaluations. Three recent IARC Working Groups pioneered inclusion of the US Environmental Protection Agency (EPA) ToxCast program high-throughput screening (HTS) data to supplement other mechanistic evidence. In Monograph V110, HTS profiles were compared between perfluorooctanoic acid (PFOA) and prototypical activators across multiple nuclear receptors. For Monograph V112-113, HTS assays were mapped to 10 key characteristics of carcinogens identified by an IARC expert group, and systematically considered as an additional mechanistic data stream. Both individual assay results and ToxPi-based rankings informed mechanistic evaluations. Activation of multiple nuclear receptors in HTS assays showed that PFOA targets not only peroxisome proliferator activated receptors, but also other receptors. ToxCast assays substantially covered 5 of 10 key characteristics, corroborating literature evidence of "induces oxidative stress" and "alters cell proliferation, cell death or nutrient supply" and filling gaps for "modulates receptor-mediated effects." Thus, ToxCast HTS data were useful both in evaluating specific mechanistic hypotheses and in contributing to the overall evaluation of mechanistic evidence. However, additional HTS assays are needed to provide more comprehensive coverage of the 10 key characteristics of carcinogens that form the basis of current IARC mechanistic evaluations.

Hayat, M. S.; Rustaman, N. Y.

2017-09-01

This study was to investigate the inquiry skills of biology pre-service teachers in one teachers college in Central Java in biotechnology lecture. The method used is a case study of 29 biology preservice teacher. Data were collected using observation sheets, questionnaires, and interview guidelines. Research findings collected through questionnaires show that most students are accustomed to asking questions and formulating biotechnology issues; Skilled in conducting experiments; Skilled in obtaining relevant information from various sources; As well as skilled at processing, analyzing and interpreting data. Based on observation: lectures are not dominated by lecturers, students are able to solve problems encountered and conduct investigations. Based on the interview towards lecturers: students are always actively involved in questioning, investigation, inquiry, problem solving and experimenting in lectures. Why do most students show good inquiry skills? Because students are accustomed to invited inquiry in biology lectures. The impact, the students become more ready to be invited to do more advanced inquiry, such as real-world application inquiry, because the skill of inquiry is essentially trained.

Genome edited animals: Learning from GM crops?

Science.gov (United States)

Bruce, Ann

2017-06-01

Genome editing of livestock is poised to become commercial reality, yet questions remain as to appropriate regulation, potential impact on the industry sector and public acceptability of products. This paper looks at how genome editing of livestock has attempted to learn some of the lessons from commercialisation of GM crops, and takes a systemic approach to explore some of the complexity and ambiguity in incorporating genome edited animals in a food production system. Current applications of genome editing are considered, viewed from the perspective of past technological applications. The question of what is genome editing, and can it be considered natural is examined. The implications of regulation on development of different sectors of livestock production systems are studied, with a particular focus on the veterinary sector. From an EU perspective, regulation of genome edited animals, although not necessarily the same as for GM crops, is advocated from a number of different perspectives. This paper aims to open up new avenues of research on genome edited animals, extending from the current primary focus on science and regulation, to engage with a wider-range of food system actors.

Classic articles and workbook: EPRI monographs on simulation of electric power production

International Nuclear Information System (INIS)

Stremel, J.P.

1991-12-01

This monograph republishes several articles including a seminal one on probabilistic production costing for electric power generation. That article is given in the original French along with a English translation. Another article, written by R. Booth, gives a popular explanation of the theory, and a workbook by B. Manhire is included that carries through a simple example step by step. The classical analysis of non-probabilistic generator dispatch by L.K. Kirchmayer is republished along with an introductory essay by J.P. Stremel that puts in perspective the monograph material. The article in French was written by H. Baleriaux, E. Jamoulle, and Fr. Linard de Guertechin and first published in Brussels in 1967. It derived a method for calculating the expected value of production costs by modifying a load duration curve through the use of probability factors that account for unplanned random generator outages. Although the paper showed how pump storage plants could be included and how linear programming could be applied, the convolution technique used in the probabilistic calculations is the part most widely applied. The tutorial paper by Booth was written in a light style, and its lucidity helped popularize the method. The workbook by Manhire also shows how the calculation can be shortened significantly using cumulants to approximate the load duration curve

Assessing Dimensions of Inquiry Practice by Middle School Science Teachers Engaged in a Professional Development Program

Lakin, Joni M.; Wallace, Carolyn S.

2015-03-01

Inquiry-based teaching promotes students' engagement in problem-solving and investigation as they learn science concepts. Current practice in science teacher education promotes the use of inquiry in the teaching of science. However, the literature suggests that many science teachers hold incomplete or incorrect conceptions of inquiry. Teachers, therefore, may believe they are providing more inquiry experiences than they are, reducing the positive impact of inquiry on science interest and skills. Given the prominence of inquiry in professional development experiences, educational evaluators need strong tools to detect intended use in the classroom. The current study focuses on the validity of assessments developed for evaluating teachers' use of inquiry strategies and classroom orientations. We explored the relationships between self-reported inquiry strategy use, preferences for inquiry, knowledge of inquiry practices, and related pedagogical content knowledge. Finally, we contrasted students' and teachers' reports of the levels of inquiry-based teaching in the classroom. Self-reports of inquiry use, especially one specific to the 5E instructional model, were useful, but should be interpreted with caution. Teachers tended to self-report higher levels of inquiry strategy use than their students perceived. Further, there were no significant correlations between either knowledge of inquiry practices or PCK and self-reported inquiry strategy use.

Science Teachers' Perceptions of the Relationship Between Game Play and Inquiry Learning

Science.gov (United States)

Mezei, Jessica M.

The implementation of inquiry learning in American science classrooms remains a challenge. Teachers' perceptions of inquiry learning are predicated on their past educational experiences, which means outdated methods of learning may influence teachers' instructional approaches. In order to enhance their understanding and ultimately their implementation of inquiry learning, teachers need new and more relevant models. This study takes a preliminary step exploring the potential of game play as a valuable experience for science teachers. It has been proposed that game play and inquiry experiences can embody constructivist processes of learning, however there has been little work done with science teachers to systematically explore the relationship between the two. Game play may be an effective new model for teacher education and it is important to understand if and how teachers relate game playing experience and knowledge to inquiry. This study examined science teachers' game playing experiences and their perceptions of inquiry experiences and evaluated teacher's recognition of learning in both contexts. Data was collected through an online survey (N=246) and a series of follow-up interviews (N=29). Research questions guiding the study were: (1) What is the nature of the relationship between science teachers' game experience and their perceptions of inquiry? (2) How do teachers describe learning in and from game playing as compared with inquiry science learning? and (3) What is the range of similarities and differences teachers articulate between game play and inquiry experiences?. Results showed weak quantitative links between science teachers' game experiences and their perceptions of inquiry, but identified promising game variables such as belief in games as learning tools, game experiences, and playing a diverse set of games for future study. The qualitative data suggests that teachers made broad linkages in terms of parallels of both teaching and learning. Teachers

The European legislation on medicinal products also addresses the medicinal use of products originating from plants. The objective of the legislation is to ensure the future existence of such products and to consider particular characteristics when assessing quality, efficacy, and safety. Two categories are defined: i) herbal medicinal products can be granted a marketing authorisation; and ii) traditional herbal medicinal products can be granted a registration based on their longstanding use if they are complying with a set of provisions ensuring their safe use. The Committee on Herbal Medicinal Products (HMPC) was established at the European Medicines Agency (EMA) to provide monographs and list entries on herbal substances and preparations thereof. Meanwhile, approx. 100 monographs have been published, which define a current scientific and regulatory standard for efficacy and safety of herbal substances and herbal preparations used in medicinal products. This harmonised European standard will facilitate the availability and adequate use of traditional herbal medicinal products and herbal medicinal products within the European Union. Consequent labelling shall also enable patients and health care professionals to differentiate medicinal products from other product categories like cosmetics, food supplements, and medical devices.

EXAMINING FACTORS AFFECTING IMPLEMENTATION OF INQUIRY-BASED LEARNING IN FINLAND AND SOUTH KOREA

Directory of Open Access Journals (Sweden)

Jingoo Kang

2016-12-01

Full Text Available Using inquiry has become a universal factor in science education, but teachers often face challenges in implementing inquiry-based learning (IBL because of, for instance, teachers’ low confidence in conducting inquiry or insufficient school resources. Much research has been conducted to identify the barriers that impede inquiry practice. However, most studies have employed small-scale qualitative methods from a single-country sample, and, thus, the effects of each factor on conducting inquiry in different educational systems have yet to be measured in one statistical model. Accordingly, this research was aimed to explore the extent to which various teacher- and school-factors have respectively affected teachers’ implementation of inquiry-based learning at lower secondary schools. To examine this issue, samples of 496 Finnish teachers in 135 lower secondary schools and 184 Korean teachers in 147 lower secondary schools were selected from the TIMSS 2011 science data set. The findings reveal that teachers’ confidence in teaching science and their collaboration to improve science teaching were strongly associated with facilitating inquiry in both countries, and these two factors’ positive effects on the implementation were partially derived from inquiry-related professional development in the Finnish sample. In addition, class size and school resources were also significantly related to inquiry practice in Finland, and the teachers’ education levels were negatively correlated with the frequency of inquiry practice in Korea. However, in both countries, the teachers’ emphasis on exams was indicated as a non-significant factor in predicting inquiry frequency. The results have implications in respect of the roles of professional development and school environment in increasing IBL practice in school science.

NTP-CERHR monograph on Soy Infant Formula.

Science.gov (United States)

2010-09-01

Soy infant formula contains soy protein isolates and is fed to infants as a supplement to or replacement for human milk or cow milk. Soy protein isolates contains estrogenic isoflavones ("phytoestrogens") that occur naturally in some legumes, especially soybeans. Phytoestrogens are non-steroidal, estrogenic compounds. In plants, nearly all phytoestrogens are bound to sugar molecules and these phytoestrogen-sugar complexes are not generally considered hormonally active. Phytoestrogens are found in many food products in addition to soy infant formula, especially soy-based foods such as tofu, soy milk, and in some over-the-counter dietary supplements. Soy infant formula was selected for evaluation by the National Toxicology Program (NTP) because of the: (1)availability of large number of developmental toxicity studies in laboratory animals exposed to the isoflavones found in soy infant formula (namely, genistein) or other soy products, as well as a number of studies on human infants fed soy infant formula, (2)the availability of information on exposures in infants fed soy infant formula, and (3)public concern for effects on infant or child development. The NTP evaluation was conducted through its Center for the Evaluation of Risks to Human Reproduction (CERHR) and completed in September 2010. The results of this soy infant formula evaluation are published in an NTP Monograph. This document contains the NTP Brief on Soy Infant Formula, which presents NTP's opinion on the potential for exposure to soy infant formula to cause adverse developmental effects in humans. The NTP Monograph also contains an expert panel report prepared to assist the NTP in reaching conclusions on soy infant formula. The NTP concluded there is minimal concern for adverse effects on development in infants who consume soy infant formula. This level of concern represents a "2" on the five-level scale of concern used by the NTP that ranges from negligible concern ("1") to serious concern ("5"). This

A Web-Based Learning Support System for Inquiry-Based Learning

Science.gov (United States)

Kim, Dong Won; Yao, Jingtao

The emergence of the Internet and Web technology makes it possible to implement the ideals of inquiry-based learning, in which students seek truth, information, or knowledge by questioning. Web-based learning support systems can provide a good framework for inquiry-based learning. This article presents a study on a Web-based learning support system called Online Treasure Hunt. The Web-based learning support system mainly consists of a teaching support subsystem, a learning support subsystem, and a treasure hunt game. The teaching support subsystem allows instructors to design their own inquiry-based learning environments. The learning support subsystem supports students' inquiry activities. The treasure hunt game enables students to investigate new knowledge, develop ideas, and review their findings. Online Treasure Hunt complies with a treasure hunt model. The treasure hunt model formalizes a general treasure hunt game to contain the learning strategies of inquiry-based learning. This Web-based learning support system empowered with the online-learning game and founded on the sound learning strategies furnishes students with the interactive and collaborative student-centered learning environment.

Shifting more than the goal posts: developing classroom norms of inquiry-based learning in mathematics

Science.gov (United States)

Makar, Katie; Fielding-Wells, Jill

2018-03-01

The 3-year study described in this paper aims to create new knowledge about inquiry norms in primary mathematics classrooms. Mathematical inquiry addresses complex problems that contain ambiguities, yet classroom environments often do not adopt norms that promote curiosity, risk-taking and negotiation needed to productively engage with complex problems. Little is known about how teachers and students initiate, develop and maintain norms of mathematical inquiry in primary classrooms. The research question guiding this study is, "How do classroom norms develop that facilitate student learning in primary classrooms which practice mathematical inquiry?" The project will (1) analyse a video archive of inquiry lessons to identify signature practices that enhance productive classroom norms of mathematical inquiry and facilitate learning, (2) engage expert inquiry teachers to collaborate to identify and design strategies for assisting teachers to develop and sustain norms over time that are conducive to mathematical inquiry and (3) support and study teachers new to mathematical inquiry adopting these practices in their classrooms. Anticipated outcomes include identification and illustration of classroom norms of mathematical inquiry, signature practices linked to these norms and case studies of primary teachers' progressive development of classroom norms of mathematical inquiry and how they facilitate learning.

GeoInquiries: Addressing a Grand Challenge for Teaching with GIS in Schools

Science.gov (United States)

DiBiase, D.; Baker, T.

2016-12-01

According to the National Research Council (2006), geographic information systems (GIS) is a powerful tool for expanding students' abilities to think spatially, a critical skill for future STEM professionals. However, educators in mainstream subjects in U.S. education have struggled for decades to use GIS effectively in classrooms. GeoInquiries are no cost, standards-based (NGSS or AP), Creative Commons-licensed instructional activities that guide inquiry around map-based concepts found in key subjects like Earth and environmental science. Web maps developed for GeoInquiries expand upon printed maps in leading textbooks by taking advantage of 21st GIS capabilities. GeoInquiry collections consist of 15 activities, each chosen to offer a map-based activity every few weeks throughout the school year. GeoInquiries use a common inquiry instructional framework, learned by many educators during their teacher preparation coursework. GeoInquiries are instructionally flexible - acting as much like building blocks for crafting custom activities as finished instructional materials. Over a half million geoinquiries will be accessed in the next twelve months - serving an anticipated 15 million students. After a generation of outreach to the educators, GIS is finally finding its way the mainstream.

Elementary Teacher's Conceptions of Inquiry Teaching: Messages for Teacher Development

Science.gov (United States)

Ireland, Joseph E.; Watters, James J.; Brownlee, Jo; Lupton, Mandy

2012-02-01

This study explored practicing elementary school teacher's conceptions of teaching in ways that foster inquiry-based learning in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning as a referent for teaching still struggles to find expression in the average teachers' pedagogy. This study drew on interview data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and answer their own questions. Understanding teachers' conceptions has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.

Identifying occupational carcinogens: an update from the IARC Monographs.

Science.gov (United States)

Loomis, Dana; Guha, Neela; Hall, Amy L; Straif, Kurt

2018-05-16

The recognition of occupational carcinogens is important for primary prevention, compensation and surveillance of exposed workers, as well as identifying causes of cancer in the general population. This study updates previously published lists of known occupational carcinogens while providing additional information on cancer type, exposure scenarios and routes, and discussing trends in the identification of carcinogens over time. Data were extracted from International Agency for Research on Cancer (IARC) Monographs covering the years 1971-2017, using specific criteria to ensure occupational relevance and provide high confidence in the causality of observed exposure-disease associations. Selected agents were substances, mixtures or types of radiation classified in IARC Group 1 with 'sufficient evidence of carcinogenicity' in humans from studies of exposed workers and evidence of occupational exposure documented in the pertinent monograph. The number of known occupational carcinogens has increased over time: 47 agents were identified as known occupational carcinogens in 2017 compared with 28 in 2004. These estimates are conservative and likely underestimate the number of carcinogenic agents present in workplaces. Exposure to these agents causes a wide range of cancers; cancers of the lung and other respiratory sites, followed by skin, account for the largest proportion. The dominant routes of exposure are inhalation and dermal contact. Important progress has been made in identifying occupational carcinogens; nevertheless, there is an ongoing need for research on the causes of work-related cancer. Most workplace exposures have not been evaluated for their carcinogenic potential due to inadequate epidemiologic evidence and a paucity of quantitative exposure data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Development and use of an instrument to measure scientific inquiry and related factors

Science.gov (United States)

Dunbar, Terry Frank

The use of the scientific inquiry method of teaching science was investigated in one district's elementary schools. The study generated data directly from Albuquerque Public Schools fourth- and fifth-grade teachers through a mail-out survey and through observation. Two forms of an inquiry evaluation research instrument (Elementary Science Inquiry Survey - ESIS) were created. The ESIS-A is a classroom observation tool. The ESIS-B is a survey questionnaire designed to collect information from teachers. The study was designed first to establish reliability and validity for both forms of the instrument. The study made use of multiple regression and exploratory factor analysis. Sources used to establish the instruments' reliability and validity included: (1) Input from an international panel (qualitative analysis of comments sent by raters and quantitative analysis of numerical ratings sent by raters); (2) Cronbach's alpha; (3) Results of factor analysis; (4) Survey respondents' comments (qualitative analysis); (5) Teacher observation data. Cronbach's alpha for the data set was .8955. Inquiry practices were reported to occur between twice per week and three times per week. Teachers' comments regarding inquiry were reported. The ESIS was used to collect inquiry self-report data and teacher background data. The teacher background data included teacher science knowledge and information about their standards awareness and implementation. The following teacher knowledge factors were positively correlated with inquiry use: semesters of college science, science workshops taken, conducted scientific research, and SIMSE (NSF institute) participation. The following standards awareness and implementation factors were positively correlated with inquiry use: familiarity with the National Science Education Standards, familiarity with New Mexico science standards, state or national standards as a curriculum selection factor, student interest as a curriculum selection factor, and "no

Full Text Available The study examines two components of metacognitive knowledge in the context of inquiry learning: metatask and metastrategic. Existing work on the topic has shown that adolescents often lacked metacognitive understanding necessary for optimal inquiry learning (Keselman & Kuhn, 2002; Kuhn, 2002a; Kuhn, Black, Keselman, & Kaplan, 2000, but demonstrated that engagement with inquiry tasks may improve it (Keselman, 2003; Kuhn & Pearsall, 1998.The aim of the study is to investigate the gains in metacognitive knowledge that occur as a result of repeated engagement with an inquiry learning task, and to examine the relationship between metacognitive knowledge and performance on the task.The participants were 34 eighth grade pupils, who participated in a self-directed experimentation task using the FILE programme (Hulshof, Wilhelm, Beishuizen, & van Rijn, 2005. The task required pupils to design and conduct experiments and to make inferences regarding the causal structure of a multivariable system. Pupils participated in four learning sessions over the course of one month. Metacognitive knowledge was assessed by the questionnaire before and after working in FILE.The results indicate that pupils improved in metacognitive knowledge following engagement with the task. However, many pupils showed insufficient metacognitive knowledge in the post-test and failed to apply newly achieved knowledge to the transfer task. Pupils who attained a higher level of metacognitive knowledge were more successful on the task than pupils who did not improve on metacognitive knowledge. A particular level of metacognitive understanding is a necessary, but not sufficient condition for successful performance on the task.

The emergence of new gene-editing technologies is profoundly transforming human therapeutics, agriculture, and industrial biotechnology. Advances in clustered regularly interspaced short palindromic repeats (CRISPR) have created a fertile environment for mass-scale manufacturing of cost-effective products ranging from basic research to translational medicine. In our analyses, we evaluated the patent landscape of gene-editing technologies and found that in comparison to earlier gene-editing techniques, CRISPR has gained significant traction and this has established dominance. Although most of the gene-editing technologies originated from the industry, CRISPR has been pioneered by academic research institutions. The spinout of CRISPR biotechnology companies from academic institutions demonstrates a shift in entrepreneurship strategies that were previously led by the industry. These academic institutions, and their subsequent companies, are competing to generate comprehensive intellectual property portfolios to rapidly commercialize CRISPR products. Our analysis shows that the emergence of CRISPR has resulted in a fivefold increase in genome-editing bioenterprise investment over the last year. This entrepreneurial movement has spurred a global biotechnology revolution in the realization of novel gene-editing technologies. This global shift in bioenterprise will continue to grow as the demand for personalized medicine, genetically modified crops and environmentally sustainable biofuels increases. However, the monopolization of intellectual property, negative public perception of genetic engineering and ambiguous regulatory policies may limit the growth of these market segments.

New science teachers' descriptions of inquiry enactment

Science.gov (United States)

Dreon, Oliver, Jr.

This phenomenological study demonstrates the influence that affective factors have on beginning teachers' ability to enact instructional practices. Through narratives shared in interviews and web log postings, two beginning science teachers' emotional engagement with their instructional practices, especially that of implementing inquiry-based instruction, and the resulting impact these emotions had on professional decision-making were evidenced. Anxiety emerged as the most significant impacting emotion on instructional decision-making with the participants. Through their stories, the two participants describe how their emotions and views of self influence whether they continue using inquiry pedagogy or alter their lesson to adopt more didactic means of instruction. These emotions arise from their feelings of being comfortable teaching the content (self-efficacy), from the unpredictability of inquiry lessons (control beliefs), from how they perceive their students as viewing them (teacher identity) and from various school constraints (agency). This research also demonstrates how intertwined these aspects are, informing each other in a complex, dialectical fashion. The participants' self-efficacy and professional identity emerge from their interactions with the community (their students and colleagues) and the perceived agency afforded by their schools' curricula and administration. By providing descriptions of teachers' experiences enacting inquiry pedagogy, this study expands our understanding of factors that influence teachers' instructional practices and provides a basis for reforming science teacher preparation.

Full Text Available A Review of: Ke, I., Gao, W., & Bronicki, J. (2017. Does title-by-title selection make a difference? A usage title analysis on print monograph purchasing. Collection Management, 42(1, 34-47. http://dx.doi.org/10.1080/01462679.2016.1249040 Abstract Objective – To compare usage of print monographs acquired through firm order to those acquired through approval plans. Design – Quantitative study. Setting – A public research university serving an annual enrollment of over 43,500 students and employing more than 2,600 faculty members in the South Central United States. Subjects – Circulation and call number data from 21,356 print books acquired through approval plans, and 23,920 print books acquired through firm orders. Methods – Item records for print materials purchased between January 1, 2011 and December 31, 2014 were extracted from the catalog and separated by acquisitions strategy into firm order and approval plan lists. Items without call numbers and materials that had been placed on course reserves were removed from the lists. The authors examined accumulated circulation counts and conducted trend analyses to examine year-to-year usage. The authors also measured circulation performance in each Library of Congress call number class; they grouped these classes into science, social science, and humanities titles. Main Results – The authors found that 31% of approval plan books and 39% of firm order books had circulated at least once. The firm order books that had circulated were used an average of 1.87 times, compared to approval plan books which were used an average of 1.47 times. The year-to-year analysis showed that the initial circulation rate for approval plan books decreased from 42% in 2011 to 14% in 2014, and from 46% to 24% for firm order books. Subject area analysis showed that medicine and military science had the highest circulation rates at over 45%, and that agriculture and bibliography titles had the lowest circulation

Full Text Available The goal of this article is to introduce activity systems as a methodological tool in narrative inquiry to gain a holistic understanding of socially shared experiences from an examination of documents. The research question was how can qualitative researchers use activity systems as a tool for engaging in narrative inquiry of socially shared experiences to uncover new meanings by constructing a story? In this article, we share a sample analysis of our experience relying on documents and media as a form of narrative to begin to understand the socially shared human activity associated with net neutrality and its potential impact on U.S. residents. We end this article with reflections of lessons learned from our activity systems guided story construction process.

The aim of this study was to evaluate the positive predictive value (PPV) and the diagnostic performance of the ultrasonographic descriptors in the fifth edition of BI-RADS, comparing with the fourth edition using video clips. From September 2013 to July 2014, 80 breast masses in 74 women (mean age, 47.5±10.7 years) from five institutions of the Korean Society of Breast Imaging were included. Two radiologists individually reviewed the static and video images and analyzed the images according to the fourth and fifth edition of BI-RADS. The PPV of each descriptor was calculated and diagnostic performances between the fourth and fifth editions were compared. Of the 80 breast masses, 51 (63.8%) were benign and 29 (36.2%) were malignant. Suspicious ultrasonographic features such as irregular shape, non-parallel orientation, angular or spiculated margins, and combined posterior features showed higher PPV in both editions (all P<0.05). No significant differences were found in the diagnostic performances between the two editions (all P>0.05). The area under the receiver operating characteristics curve was higher in the fourth edition (0.708 to 0.690), without significance (P=0.416). The fifth edition of the BI-RADS ultrasound lexicon showed comparable performance to the fourth edition and can be useful in the differential diagnosis of breast masses using ultrasonography

The editorial process is analyzed, and five levels of edit are identified. These levels represent cumulative combinations of nine types of edit: (1) coordination, (2) policy, (3) integrity, (4) screening, (5) copy clarification, (6) Mechanical Style, (7) Language, and (9) substantive. The levels and types of edit, although developed for specific use with external reports at the Jet Propulsion Laboratory, cover the general range of technical editing, especially as it applies to an in-house technical publications organization. Each type of edit is set forth in terms of groups of actions to be performed by the editor. The edit-level concept has enhanced understanding and communication among editors, authors, and publications managers concerning the specific editorial work to be done on each manuscript. It has also proved useful as a management tool for estimating and monitoring cost.

Monograph of Coccinia (Cucurbitaceae).

Science.gov (United States)

Holstein, Norbert

2015-01-01

This monograph deals with all 95 names described in the Cucurbitaceae genus Coccinia and recognizes 25 species. Taxonomic novelties are Cocciniaadoensisvar.aurantiaca (C.Jeffrey) Holstein, stat. nov., Cocciniasessilifoliavar.variifolia (A.Meeuse) Holstein, stat. nov., and Cocciniaadoensisvar.jeffreyana Holstein, var. nov. For the 25 species 3157 collections were examined, of which 2024 were georeferenced to produce distribution maps. All species are distributed in sub-Saharan Africa with one species, Cocciniagrandis, extending from Senegal in West Africa east to Indonesia and being naturalized on Pacific Islands, in Australia, the Caribbean, and South America. Coccinia species are dioecious creepers or climbers with simple or bifid tendrils that occupy a range of habitats from arid scrubland, woodlands to lowland rainforest and mist forest. The corolla of Coccinia species is sympetalous, usually pale yellow to orange, and 1 to 4.5 cm long. Pollination is by bees foraging for pollen or nectar. After pollination, the developing ovary often exhibits longitudinal mottling, which usually disappears during maturation. All species produce berries with a pericarp in reddish colors (orange-red through to scarlet red), hence the generic name. The globose to cylindrical fruits contain numerous grayish-beige flat to lenticular seeds. Chromosome numbers are 2n = 20, 24, and 22 + XX/XY. Many Coccinia species are used for food, either as roasted tubers, greens as spinach, or the fruits as vegetables. Medicinal value is established in Cocciniagrandis, of which leaves and sap are used against diabetes.

Incorporating Inquiry into Upper-Level Homework Assignments: The Mini-Journal

Science.gov (United States)

Whittington, A. G.; Speck, A. K.; Witzig, S. B.; Abell, S. K.

2009-12-01

The U.S. National Science Education Standards provide guidelines for teaching science through inquiry, where students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills. Inquiry activities include reading scientific literature, generating hypotheses, designing and carrying out investigations, interpreting data, and formulating conclusions. Inquiry-based instruction emphasizes questions, evidence, and explanation, the essential features of inquiry. As part of an NSF-funded project, “CUES: Connecting Undergraduates to the Enterprise of Science,” new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). We engage students in inquiry-based learning by presenting homework exercises as “mini-journal” articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the minijournal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. The key differences between the old and new formats include (i) the active participation of the students in

Disciplined Improvisation: Characteristics of Inquiry in Mindfulness-Based Teaching.

Science.gov (United States)

Crane, Rebecca S; Stanley, Steven; Rooney, Michael; Bartley, Trish; Cooper, Lucinda; Mardula, Jody

Evidence for the effectiveness of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) is rapidly growing as interest in this field expands. By contrast, there are few empirical analyses of the pedagogy of MBSR and MBCT. Development of the evidence base concerning the teaching of MBCT or MBSR would support the integrity of the approach in the context of rapid expansion. This paper describes an applied conversation analysis (CA) of the characteristics of inquiry in the MBSR and MBCT teaching process. Audio-recordings of three 8-week MBCT and MBSR classes, with 24, 12, and 6 participants, were transcribed and systematically examined. The study focused on the teacher-led interactive inquiry which takes place in each session after a guided meditation practice. The study describes and analyzes three practices within the inquiry process that can be identified in sequences of talk: turn-taking talk involving questions and reformulations; the development of participant skills in a particular way of describing experience; and talk that constructs intersubjective connection and affiliation within the group. CA enables fine-grained analysis of the interactional work of mindfulness-based inquiry. Inquiry is a process of disciplined improvisation which is both highly specific to the conditions of the moment it took place in and uses repeated and recognizable patterns of interaction.

Narrative inquiry: Locating Aboriginal epistemology in a relational methodology.

Science.gov (United States)

Barton, Sylvia S

2004-03-01

This methodology utilizes narrative analysis and the elicitation of life stories as understood through dimensions of interaction, continuity, and situation. It is congruent with Aboriginal epistemology formulated by oral narratives through representation, connection, storytelling and art. Needed for culturally competent scholarship is an experience of research whereby inquiry into epiphanies, ritual, routines, metaphors and everyday experience creates a process of reflexive thinking for multiple ways of knowing. Based on the sharing of perspectives, narrative inquiry allows for experimentation into creating new forms of knowledge by contextualizing diabetes from the experience of a researcher overlapped with experiences of participants--a reflective practice in itself. The aim of this paper is to present narrative inquiry as a relational methodology and to analyse critically its appropriateness as an innovative research approach for exploring Aboriginal people's experience living with diabetes. Narrative inquiry represents an alternative culture of research for nursing science to generate understanding and explanation of Aboriginal people's 'diabetic self' stories, and to coax open a window for co-constructing a narrative about diabetes as a chronic illness. The ability to adapt a methodology for use in a cultural context, preserve the perspectives of Aboriginal peoples, maintain the holistic nature of social problems, and value co-participation in respectful ways are strengths of an inquiry partial to a responsive and embodied scholarship.

Connecting Inquiry and Values in Science Education. An Approach Based on John Dewey's Philosophy

Science.gov (United States)

Lee, Eun Ah; Brown, Matthew J.

2018-03-01

Conducting scientific inquiry is expected to help students make informed decisions; however, how exactly it can help is rarely explained in science education standards. According to classroom studies, inquiry that students conduct in science classes seems to have little effect on their decision-making. Predetermined values play a large role in students' decision-making, but students do not explore these values or evaluate whether they are appropriate to the particular issue they are deciding, and they often ignore relevant scientific information. We explore how to connect inquiry and values, and how this connection can contribute to informed decision-making based on John Dewey's philosophy. Dewey argues that scientific inquiry should include value judgments and that conducting inquiry can improve the ability to make good value judgments. Value judgment is essential to informed, rational decision-making, and Dewey's ideas can explain how conducting inquiry can contribute to make an informed decision through value judgment. According to Dewey, each value judgment during inquiry is a practical judgment guiding action, and students can improve their value judgments by evaluating their actions during scientific inquiry. Thus, we suggest that students need an opportunity to explore values through scientific inquiry and that practicing value judgment will help informed decision-makings.

New Perspectives on Technical Editing by Avon J. Murphy (ed.) ISBN : 978-0895033949 (2010) Baywood Publishing Company Inc, Hardcover, 210 pages, 35.5 GBP This book presents a collection of 10 chapters dealing with diverse aspects of technical editing (ie, editorial planning, and analysis and structural changes made to other people's technological documents): research in technical editing, trends and teaching of technical editing, copyediting, and technical journal editing. The role and function of the modern journal and book editor is also dealt with in detail. Each chapter is written by an expert in the field: senior editors, university professors in technical communication, technical writers and linguists. The ever-evolving role of the editor is clearly elucidated in several historical reviews, and in the descriptions of the expectations for the future. A very striking aspect of this book is its extensive collection of bibliographic resources: every chapter lists dozens of very useful references, and the closing chapter, and annotated bibliography, contain many not so well known references, and are most useful. All in all, the book is a treasure trove listing more than 400 references, in addition to numerous webpage URLs embedded in the texts. The book is designed to help the reader to understand current practices and norms in technical editing, and to help to take action in editing as well as in teaching and educating would-be editors. The audience for this book thus includes editors and teachers, but also writers, researchers and students. A deep reading of this book will result in a better understanding of the difference between full technical editing and its much narrower component so well known as copyediting, and will convince any prospective editor that editing should not be undertaken if the people involved do not master the art of precision and accuracy in technical (as well as in human) communication, do not possess the technical know how and computer

Mentoring a new science teacher in reform-based ways: A focus on inquiry

Science.gov (United States)

Schomer, Scott D.

The processes, understandings, and uses of inquiry are identified by the National Science Education Standards (National Research Council, 1996) as a key component of science instruction. Currently, there are few examples in the literature demonstrating how teachers go about co-constructing inquiry-based activities and how mentors can promote the use of reform-based practices by novices. The purpose of this interpretive case study was to investigate how a mentor and her protege collaboratively developed, implemented and assessed three inquiry-based experiences. The questions that guided this research were: (1) How does the mentor assist protege growth in the development, implementation and assessment of inquiry-based experiences for secondary science students? (2) How are the protege's perceptions of inquiry influenced by her participation in developing, implementing and assessing inquiry-based experiences for secondary science students? The co-construction of the inquiry activities and the facilitation provided by the mentor represented Lev Vygotsky's (1978) social construction of information as the mentor guided the protege beyond her cognitive zone of proximal development. The participants in this study were a veteran science teacher who was obtaining her mentor certification, or Teacher Support Specialist, and her protege who was a science teacher in the induction phase of her career. Data were collected through in-depth, semi-structured interviews, tape recordings of planning sessions, researcher field notes, and email reflections during the co-construction process. Inductive analysis of the data led to the identification of common categories and subsequent findings, which reflected what the mentor and protege discussed about inquiry and the process of collaboration. The six themes that emerged from this study led to several implications that are significant for science teacher preparation and the mentoring community. The teachers indicated tools, such as the

Open access monographs: a humanities research perspective

Directory of Open Access Journals (Sweden)

Dr Jim Cheshire

2014-04-01

Full Text Available This article discusses the thoughts of a humanities researcher in relation to open access (OA publishing. Digital media have dramatically improved access to historic texts but library e-books are frustrating due to software and loan arrangements. Authors of illustrated books risk losing control of book design, although new media offer opportunities to improve image quality and access. Alfred Tennyson's career shows that authors have been sensitive about the physical form of their work since the Victorian period and ignoring the material significance of the book could make us overlook the fundamental changes that the e-book represents. Monographs retain value as a way of evaluating substantive research projects and those published through the OA process will have great advantages over the commercial e-book. ‘Green’ OA publishing is impractical for humanities scholars and funded ‘gold’ OA publishing is likely to involve a labour-intensive application process.

Anstey, Lauren M

2017-11-01

Despite advances to move anatomy education away from its didactic history, there is a continued need for students to contextualize their studies to make learning more meaningful. This article investigates authentic learning in the context of an inquiry-based approach to learning human gross anatomy. Utilizing a case-study design with three groups of students (n = 18) and their facilitators (n = 3), methods of classroom observations, interviews, and artifact collection were utilized to investigate students' experiences of learning through an inquiry project. Qualitative data analysis through open and selective coding produced common meaningful themes of group and student experiences. Overall results demonstrate how the project served as a unique learning experience where learners engaged in the opportunity to make sense of anatomy in context of their interests and wider interdisciplinary considerations through collaborative, group-based investigation. Results were further considered in context of theoretical frameworks of inquiry-based and authentic learning. Results from this study demonstrate how students can engage anatomical understandings to inquire and apply disciplinary considerations to their personal lives and the world around them.

Full Text Available The purpose of this study was to examine the effects of four-year integrated information literacy instruction via a framework of inquiry-based learning on elementary students’ memory and comprehension. Moderating factors of students’ academic achievement was another focus of this study. The subjects were 72 students who have participated in this study since they entered an elementary school in Chiayi district. This elementary school adopted the integrated information literacy instruction, designed by the researchers and elementary school teachers, and integrated it into various subject matters via a framework of inquiry-based learning, such as Super 3 and Big6 models. A series of inquiry-based integrated information literacy instruction has been implemented since the second semester of the subjects’ first grade. A total of seven inquiry learning projects has been implemented from grade one through grade four. Fourteen instruments were used as pretests and posttests to assess students’ factual recall and conceptual understanding of subject contents in different projects. The results showed that inquiry-based integrated information literacy instruction couldhelp students memorize facts and comprehend concepts of subject contents. Regardless ofacademic achievements, if students would like to devote their efforts to inquiry processes, their memory and comprehension of subject contents improvedeffectively. However, students of low-academic achievement might need more time to be familiar with the inquiry-based learning strategy.

Hutchins, Kristen L.; Friedrichsen, Patricia J.

2012-12-01

The purpose of this study was to investigate how science faculty members' belief systems about inquiry-based teaching changed through their experience in a professional development program. The program was designed to support early career science faculty in learning about inquiry and incorporating an inquiry-based approach to teaching laboratories. Data sources for this qualitative study included three semi-structured interviews, observations during the program and during faculty members' implementation in their courses, and a researcher's journal. In the first phase of data analysis, we created profiles for each of the four participants. Next, we developed assertions, and tested for confirming and disconfirming evidence across the profiles. The assertions indicated that, through the professional development program, participants' knowledge and beliefs about inquiry-based teaching shifted, placing more value on student-directed learning and classroom inquiry. Participants who were internally motivated to participate and held incoming positive attitudes toward the mini-journal inquiry-based approach were more likely to incorporate the approach in their future practice. Students' responses played a critical role in participants' belief systems and their decision to continue using the inquiry-based format. The findings from this study have implications for professional development design.

Ford, Danielle J.; Fifield, Steve; Madsen, John; Qian, Xiaoyu

2013-10-01

We describe the Science Semester, a semester-long course block that integrates three science courses and a science education methods course for elementary teacher education majors, and examine prospective elementary teachers’ developing conceptions about inquiry, science teaching efficacy, and reflections on learning through inquiry. The Science Semester was designed to provide inquiry-oriented and problem-based learning experiences, opportunities to examine socially relevant issues through cross-disciplinary perspectives, and align with content found in elementary curricula and standards. By the end of the semester, prospective elementary teachers moved from naïve to intermediate understandings of inquiry and significantly increased self-efficacy for science teaching as measured on one subscore of the STEBI-B. Reflecting on the semester, prospective teachers understood and appreciated the goals of the course and the PBL format, but struggled with the open-ended and student-directed elements of the course.

Supporting Collective Inquiry: A Technology Framework for Distributed Learning

Science.gov (United States)

Tissenbaum, Michael

This design-based study describes the implementation and evaluation of a technology framework to support smart classrooms and Distributed Technology Enhanced Learning (DTEL) called SAIL Smart Space (S3). S3 is an open-source technology framework designed to support students engaged in inquiry investigations as a knowledge community. To evaluate the effectiveness of S3 as a generalizable technology framework, a curriculum named PLACE (Physics Learning Across Contexts and Environments) was developed to support two grade-11 physics classes (n = 22; n = 23) engaged in a multi-context inquiry curriculum based on the Knowledge Community and Inquiry (KCI) pedagogical model. This dissertation outlines three initial design studies that established a set of design principles for DTEL curricula, and related technology infrastructures. These principles guided the development of PLACE, a twelve-week inquiry curriculum in which students drew upon their community-generated knowledge base as a source of evidence for solving ill-structured physics problems based on the physics of Hollywood movies. During the culminating smart classroom activity, the S3 framework played a central role in orchestrating student activities, including managing the flow of materials and students using real-time data mining and intelligent agents that responded to emergent class patterns. S3 supported students' construction of knowledge through the use individual, collective and collaborative scripts and technologies, including tablets and interactive large-format displays. Aggregate and real-time ambient visualizations helped the teacher act as a wondering facilitator, supporting students in their inquiry where needed. A teacher orchestration tablet gave the teacher some control over the flow of the scripted activities, and alerted him to critical moments for intervention. Analysis focuses on S3's effectiveness in supporting students' inquiry across multiple learning contexts and scales of time, and in

Procedural status of prosecutor during the conduction of short inquiry

Directory of Open Access Journals (Sweden)

Nikanorov S.A.

2014-12-01

Full Text Available The issues of conducting short inquiry from the position of prosecutor’s procedural status are considered. Low rate of applying short inquiry is caused by ignorance about this procedural form among the participants in criminal procedure. The initiators of conducting short inquiry were not suspects (accused, but their lawyers who followed by their own ambitions, not by the interests of defendants. The insufficiency of total time of short inquiry is noted. The author proposes to minimize prosecutors’ paperwork, notably to concentrate their attention on collecting crime data by conducting secret investigation operations, receiving explanations and other documentation. Obtained data should be processed according to police regulations. Confession of guilt, recognition of damage and consent with legal assessment of criminal act allow to collect only the evidence, indicating crime event and complicacy of a person (expertise should be established on court’s initiative. The favourable conditions of adequacy of collected evidence for establishing crime event, character and amount of damage, as well as guilt of committing crime are confirmed. The right of investigators not to examine evidences if they were not contradicted by suspect, victim or his/her representative (predetermined strength of evidence is criticized. There is no short effective procedure of trying criminal cases with rational division of powers among the authorities, conducting criminal proceeding. The author proves the necessity of reasonable approach to prosecutor’s supervision of conducting short inquiry. Main tendency of further improvement of short inquiry procedure is redivision of powers among agencies in charge of preliminary investigation and prosecutor’s office.

Towards a Knowledge Building Community: From Guided to Self-Organized Inquiry

Stefano Cacciamani

2010-11-01

Full Text Available Over four academic years a design experiment was conducted involving four online university courses with the goal of shifting from Guided to Self-Organized Inquiry to foster Knowledge Building communities in the classroom. Quantitative analyses focused on notes contributed to collective knowledge spaces, as well as reading and building-on notes of others. All team members, including teachers, contributed at high levels. Students tended to produce more notes in the guided-inquiry approach but read more and demonstrated more even distribution of work as part of self-organized inquiry. Qualitative data focused on strategies students reported as new to their school experience. Strategies fell into three categories common to both guided and self-organizing inquiry: elaborating course content for depth of understanding, collaboration in an online environment, and metacognition, with greater reflection on idea development. Distinctive aspects of self-organized inquiry, according to student reports, included going beyond given information, linking new understandings and personal experiences, attention to the collective works of the community, and learning from instructor’s strategies.

2011-08-01

The United States Pharmacopeia (USP) monograph for unfractionated heparin (UFH) was revised in October 2009. This revision was anticipated, based upon in vitro tests, to reduce UFH potency by approximately 10%. To study the potential in vivo consequences of the monograph change, we evaluated activated partial thromboplastin time (aPTT) and activated clotting time (ACT) responses in animals. Female mini-pigs and monkeys (n=8/species) were administered intravenously 60, 54, 48, or 42 U/kg and 50, 45, 40, or 35 U/kg "old" (pre-USP revision) UFH, respectively, in a Williams 4×4 crossover design. Blood samples for aPTT and ACT were collected at 15 min after dosing. The same study design was then repeated using "new" (post-USP revision) UFH. Mean "new" UFH aPTT and ACT values were generally lower than those for "old" UFH although individual animal responses varied considerably. The aPTT and ACT response was generally dose-proportional for both "old" and "new" UFH. These studies indicate that the USP monograph alteration for UFH may result in a modest reduction in the anticoagulant response across a population, but the variability in animal responses underscores the importance of individualization of clinical UFH dosing and the importance of anticoagulant test monitoring.

Science.gov (United States)

Boo, Yoo-Kyung; Lim, Hyun-Sook; Kim, Jung-Eun; Kim, Kyoung-Beom; Won, Young-Joo

2017-06-25

Background: In Korea, the national cancer database was constructed after the initiation of the national cancer registration project in 1980, and the annual national cancer registration report has been published every year since 2005. Consequently, data management must begin even at the stage of data collection in order to ensure quality. Objectives: To determine the suitability of cancer registries’ inquiry tools through the inquiry analysis of the Korea Central Cancer Registry (KCCR), and identify the needs to improve the quality of cancer registration. Methods: Results of 721 inquiries to the KCCR from 2000 to 2014 were analyzed by inquiry year, question type, and medical institution characteristics. Using Stata version 14.1, descriptive analysis was performed to identify general participant characteristics, and chi-square analysis was applied to investigate significant differences in distribution characteristics by factors affecting the quality of cancer registration data. Results: The number of inquiries increased in 2005–2009. During this period, there were various changes, including the addition of cancer registration items such as brain tumors and guideline updates. Of the inquirers, 65.3% worked at hospitals in metropolitan cities and 60.89% of hospitals had 601–1000 beds. Tertiary hospitals had the highest number of inquiries (64.91%), and the highest number of questions by type were 353 (48.96%) for histological codes, 92 (12.76%) for primary sites, and 76 (10.54%) for reportable. Conclusions: A cancer registration inquiry system is an effective method when not confident about codes during cancer registration, or when confronting cancer cases in which previous clinical knowledge or information on the cancer registration guidelines are insufficient.

Reforming High School Science for Low-Performing Students Using Inquiry Methods and Communities of Practice

Science.gov (United States)

Bolden, Marsha Gail

Some schools fall short of the high demand to increase science scores on state exams because low-performing students enter high school unprepared for high school science. Low-performing students are not successful in high school for many reasons. However, using inquiry methods have improved students' understanding of science concepts. The purpose of this qualitative research study was to investigate the teachers' lived experiences with using inquiry methods to motivate low-performing high school science students in an inquiry-based program called Xtreem Science. Fifteen teachers were selected from the Xtreem Science program, a program designed to assist teachers in motivating struggling science students. The research questions involved understanding (a) teachers' experiences in using inquiry methods, (b) challenges teachers face in using inquiry methods, and (c) how teachers describe student's response to inquiry methods. Strategy of data collection and analysis included capturing and understanding the teachers' feelings, perceptions, and attitudes in their lived experience of teaching using inquiry method and their experience in motivating struggling students. Analysis of interview responses revealed teachers had some good experiences with inquiry and expressed that inquiry impacted their teaching style and approach to topics, and students felt that using inquiry methods impacted student learning for the better. Inquiry gave low-performing students opportunities to catch up and learn information that moved them to the next level of science courses. Implications for positive social change include providing teachers and school district leaders with information to help improve performance of the low performing science students.

Foster, Jamie S; Lemus, Judith D

2015-01-01

Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

Inquiries into Malaysia's socio-technical disasters: recommendations and lessons learnt.

Said, Aini Mat; Ahmadun, Fakhru'l-Razi; Abdul Kadir, Razali; Daud, Mohamed

2009-04-01

Most democratic countries hold inquiries into disasters. One of their key functions is to establish the cause of an event and to learn lessons in order to prevent a recurrence. In addition, they offer an opportunity for communal catharsis, permitting the public to vent anger, distress and frustration and to exert pressure for policy changes. Malaysia has experienced six landmark socio-technical disasters since 1968, which resulted in the proposal or amendment of various safety/emergency acts and regulations. The authors used a grounded theory approach utilising a constant comparative method to analyse the recommendations made by the inquiries into these events. Data indicate that social and technical recommendations comprise 85 and 15 per cent, respectively, of the total recommendations made by the inquiry committees. This paper offers suggestions for improving the management of inquiry tribunals, as they will remain a valuable source of information for society and corporations to learn from past incidents.

Mediated Plastid RNA Editing in Plant Immunity

Science.gov (United States)

García-Andrade, Javier; Ramírez, Vicente; López, Ana; Vera, Pablo

2013-01-01

Plant regulatory circuits coordinating nuclear and plastid gene expression have evolved in response to external stimuli. RNA editing is one of such control mechanisms. We determined the Arabidopsis nuclear-encoded homeodomain-containing protein OCP3 is incorporated into the chloroplast, and contributes to control over the extent of ndhB transcript editing. ndhB encodes the B subunit of the chloroplast NADH dehydrogenase-like complex (NDH) involved in cyclic electron flow (CEF) around photosystem I. In ocp3 mutant strains, ndhB editing efficiency decays, CEF is impaired and disease resistance to fungal pathogens substantially enhanced, a process recapitulated in plants defective in editing plastid RNAs encoding NDH complex subunits due to mutations in previously described nuclear-encoded pentatricopeptide-related proteins (i.e. CRR21, CRR2). Furthermore, we observed that following a pathogenic challenge, wild type plants respond with editing inhibition of ndhB transcript. In parallel, rapid destabilization of the plastidial NDH complex is also observed in the plant following perception of a pathogenic cue. Therefore, NDH complex activity and plant immunity appear as interlinked processes. PMID:24204264

Issues regarding transient analysis examined by the Sizewell B Public Inquiry

International Nuclear Information System (INIS)

Farmer, P.R.; Dunnicliffe, C.J.

1988-01-01

Issues on PWR safety transient analysis that were discussed at the Sizewell B Public Inquiry are presented. The Public Inquiry was set up by the UK Government under an Inspector, Sir Frank Layfield, to examine all aspects of the construction, safety and operation of a 1200 MW(e) PWR on the Sizewell site. The terms of reference were broad ranging, and the constitution of the Inquiry was to make a recommendation under three Acts of Parliament which apply to the construction and operation of nuclear electrical plant. The Inquiry also covered local planning aspects, which are the responsibility of the Local Authority - in this case the Suffolk County Council. The Inspector examined and made recommendations on the safety of the Station, but consideration by Public Inquiry is outside the formal safety and licensing process, which is the business of the Utility (the CEGB) and the Nuclear Installations Inspectorate (the NII). The paper therefore takes a broader look at the question of safety, dealing with the licensing process, the requirements of the safety case and the forward strategies adopted by the CEGB in terms of research and development. This is considered for transient analysis, and the aim is to set the discussions and conclusions of the Public Inquiry into their proper context with regard to nuclear safety in the UK. The Inquiry went into some depth on the topic of LOCA, as an example of safety analysis. In the summary of the evidence and cross-examination the Inspector accepted the adequacy of the LOCA safety case without major reservations, and was satisfied further work in progress would resolve any residual criticisms. In particular support was given for the CEGB commitment to the development and use of more physically realistic calculational methods

Lecture to inquiry: The transformation of a tech prep biology teacher

Science.gov (United States)

Haskell, Deborah Harris

As teachers implement the National Science Education Standards (NRC, 1996) many have to reform the instructional methods they have used throughout their careers. This case study examines the transformation of Laurie, a 20-year teacher, during her first year of change from a "traditional" textbook/lecture style of teaching to a facilitator of an inquiry-based classroom. Implementing change requires not only pedagogical expertise, but also the belief that the modifications can be made and that the outcomes are significant. Using Bandura's social cognitive theory as a framework, changes in Laurie's self-efficacy, outcome expectancy, and motivation are followed throughout the transition. During her first year of change, Laurie used worksheets, small group activities, and guided inquiry activities, all strategies in which she had high self-efficacy and experienced positive student outcomes. She rarely used class forums, authentic assessment, and formative assessment. Factors that influenced her change were experiential professional development opportunities that allowed her to practice inquiry-based techniques, a change in her teaching environment from college prep chemistry to tech prep biology, autonomy regarding classroom decisions, and reflective decision making as she learned through experience. Using a standards-based biology textbook increased her self-efficacy toward using inquiry-based practices. The textbook format of embedding text in activities rather than adding activities to the text resulted in an increase of the number and frequency of activities done. Facilitating the textbook's Guided Inquiries and Extended Inquiries helped Laurie gain experience with inquiry-based methods. She also realized that when building from the students' concrete experiences, her students were able to attain higher-level thinking skills. The study revealed six factors contributing to Laurie's change process: (a) experiential professional development, (b) motivation for change

Do science coaches promote inquiry-based instruction in the elementary science classroom?

Science.gov (United States)

Wicker, Rosemary Knight

The South Carolina Mathematics and Science Coaching Initiative established a school-based science coaching model that was effective in improving instruction by increasing the level of inquiry-based instruction in elementary science classrooms. Classroom learning environment data from both teacher groups indicated considerable differences in the quality of inquiry instruction for those classrooms of teachers supported by a science coach. All essential features of inquiry were demonstrated more frequently and at a higher level of open-ended inquiry in classrooms with the support of a science coach than were demonstrated in classrooms without a science coach. However, from teacher observations and interviews, it was determined that elementary schoolteacher practice of having students evaluate conclusions and connect them to current scientific knowledge was often neglected. Teachers with support of a science coach reported changes in inquiry-based instruction that were statistically significant. This mixed ethnographic study also suggested that the Mathematics and Science Coaching Initiative Theory of Action for Instructional Improvement was an effective model when examining the work of science coaches. All components of effective school infrastructure were positively impacted by a variety of science coaching strategies intended to promote inquiry. Professional development for competent teachers, implementation of researched-based curriculum, and instructional materials support were areas highly impacted by the work of science coaches.

Boneless Pose Editing and Animation

DEFF Research Database (Denmark)

Bærentzen, Jakob Andreas; Hansen, Kristian Evers; Erleben, Kenny

2007-01-01

In this paper, we propose a pose editing and animation method for triangulated surfaces based on a user controlled partitioning of the model into deformable parts and rigid parts which are denoted handles. In our pose editing system, the user can sculpt a set of poses simply by transforming...... the handles for each pose. Using Laplacian editing, the deformable parts are deformed to match the handles. In our animation system the user can constrain one or several handles in order to define a new pose. New poses are interpolated from the examples poses, by solving a small non-linear optimization...... problem in order to obtain the interpolation weights. While the system can be used simply for building poses, it is also an animation system. The user can specify a path for a given constraint and the model is animated correspondingly....

The expression of apoB mRNA editing factors is not the sole determinant for the induction of editing in differentiating Caco-2 cells

International Nuclear Information System (INIS)

Galloway, Chad A.; Smith, Harold C.

2010-01-01

Apolipoprotein B mRNA is edited at cytidine 6666 in the enterocytes lining the small intestine of all mammals; converting a CAA codon to a UAA stop codon. The conversion is ∼80% efficient in this tissue and leads to the expression of the truncated protein, ApoB48, essential for secretion of dietary lipid as chylomicrons. Caco-2 cell raft cultures have been used as an in vitro model for the induction of editing activity during human small intestinal cell differentiation. This induction of apoB mRNA editing has been ascribed to the expression of APOBEC-1. In agreement our data demonstrated differentiation-dependent induction of expression of the editing enzyme APOBEC-1 and in addition we show alternative splicing of the essential auxiliary factor ACF. However, transfection of these editing factors in undifferentiated proliferating Caco-2 cells was not sufficient to induce robust apoB mRNA editing activity. Only differentiation of Caco-2 cells could induce more physiological like levels of apoB mRNA editing. The data suggested that additional regulatory mechanism(s) were induced by differentiation that controlled the functional activity of editing factors.

Genome Editing in Sugarcane: Challenges ahead

Directory of Open Access Journals (Sweden)

Chakravarthi Mohan

2016-10-01

Full Text Available Genome editing opens new and unique opportunities for researchers to enhance crop production. Until 2013, the zinc finger nucleases (ZFNs and transcription activator-like effector nucleases (TALENs were the key tools used for genome editing applications. The advent of RNA-guided engineered nucleases - the type II clustered regularly interspaced short palindromic repeat (CRISPR/Cas9 (CRISPR-associated system from Streptococcus pyogenes holds great potential since it is simple, effective and more versatile than ZFNs and TALENs. CRISPR/Cas9 system has already been successfully employed in several crop plants. Use of these techniques is in its infant stage in sugarcane. Jung and Altpeter (2016 have reported TALEN mediated approach for the first time to reduce lignin content in sugarcane to make it amenable for biofuel production. This is so far the only report describing genome editing in sugarcane. Large genome size, polyploidy, low transformation efficiency, transgene silencing and lack of high throughput screening techniques are certainly great challenges for genome editing in sugarcane which would be discussed in detail in this review.

Edit propagation using geometric relationship functions

KAUST Repository

Guerrero, Paul; Jeschke, Stefan; Wimmer, Michael; Wonka, Peter

2014-01-01

We propose a method for propagating edit operations in 2D vector graphics, based on geometric relationship functions. These functions quantify the geometric relationship of a point to a polygon, such as the distance to the boundary or the direction to the closest corner vertex. The level sets of the relationship functions describe points with the same relationship to a polygon. For a given query point, we first determine a set of relationships to local features, construct all level sets for these relationships, and accumulate them. The maxima of the resulting distribution are points with similar geometric relationships. We show extensions to handle mirror symmetries, and discuss the use of relationship functions as local coordinate systems. Our method can be applied, for example, to interactive floorplan editing, and it is especially useful for large layouts, where individual edits would be cumbersome. We demonstrate populating 2D layouts with tens to hundreds of objects by propagating relatively few edit operations. © 2014 ACM 0730-0301/2014/03- ART15 $15.00.

Inquiry-based science education: towards a pedagogical framework for primary school teachers

Science.gov (United States)

van Uum, Martina S. J.; Verhoeff, Roald P.; Peeters, Marieke

2016-02-01

Inquiry-based science education (IBSE) has been promoted as an inspiring way of learning science by engaging pupils in designing and conducting their own scientific investigations. For primary school teachers, the open nature of IBSE poses challenges as they often lack experience in supporting their pupils during the different phases of an open IBSE project, such as formulating a research question and designing and conducting an investigation. The current study aims to meet these challenges by presenting a pedagogical framework in which four domains of scientific knowledge are addressed in seven phases of inquiry. The framework is based on video analyses of pedagogical interventions by primary school teachers participating in open IBSE projects. Our results show that teachers can guide their pupils successfully through the process of open inquiry by explicitly addressing the conceptual, epistemic, social and/or procedural domain of scientific knowledge in the subsequent phases of inquiry. The paper concludes by suggesting further research to validate our framework and to develop a pedagogy for primary school teachers to guide their pupils through the different phases of open inquiry.

IMRT fluence map editing to control hot and cold spots

International Nuclear Information System (INIS)

Taylor Cook, J.; Tobler, Matt; Leavitt, Dennis D.; Watson, Gordon

2005-01-01

Manually editing intensity-modulated radiation therapy (IMRT) fluence maps effectively controls hot and cold spots that the IMRT optimization cannot control. Many times, re-optimizing does not reduce the hot spots or increase the cold spots. In fact, re-optimizing only places the hot and cold spots in different locations. Fluence-map editing provides manual control of dose delivery and provides the best treatment plan possible. Several IMRT treatments were planned using the Varian Eclipse planning system. We compare the effects on dose distributions between fluence-map editing and re-optimization, discuss techniques for fluence-map editing, and analyze differences between fluence editing on one beam vs. multiple beams. When editing a beam's fluence map, it is essential to choose a beam that least affects dose to the tumor and critical structures. Editing fluence maps gives an advantage in treatment planning and provides controlled delivery of IMRT dose

Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory

Science.gov (United States)

Donnelly, Dermot; O'Reilly, John; McGarr, Oliver

2013-08-01

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a `talk-aloud' manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.

Explanatory Supplement to the Astronomical Almanac, Third Edition

Science.gov (United States)

Seidelmann, P. Kenneth; Urban, S. E.

2010-01-01

"The Explanatory Supplement to the Astronomical Almanac" (hereafter "The Explanatory Supplement") is a comprehensive reference book on the topic of positional astronomy, covering the theories and algorithms used to produce "The Astronomical Almanac" (AsA), an annual publication produced jointly by the Nautical Almanac Office of the US Naval Observatory (USNO) and Her Majesty's Nautical Almanac Office (HMNAO) of the UK Hydrographic Office. The first edition of The Explanatory Supplement appeared in 1961 and was reprinted with amendments during the 1970s. The second edition was printed in 1992 and reprinted until 2006. Since the second edition, several changes have taken place in positional astronomy regarding reference systems and internationally accepted models, data sets, and computational methods; these have been incorporated into the AsA. Additionally, the data presented in the AsA have been modified over the years, with new tables being added and some being discontinued. Given these changes, a new edition of The Explanatory Supplement is appropriate. The third edition has been in development for the last few years and will be available in 2010. The book is organized similarly to the second (1991) edition, with each chapter written by subject matter experts. Authors from USNO and HMNAO contributed to the majority of the book, but there are authors from Jet Propulsion Laboratory, Technical University of Dresden, National Geospatial-Intelligence Agency, University of Texas Austin, and University of Virginia. This paper will discuss this latest edition of the Explanatory Supplement.

Unethical conduct by the nurse: a critical discourse analysis of Nurses Tribunal inquiries.

Dixon, Kathleen A

2013-08-01

The aim of this study was to uncover and critically examine hidden assumptions that underpin the findings of nurses' unethical conduct arising from inquiries conducted by the Nurses Tribunal in New South Wales. This was a qualitative study located within a post-structural theoretical framework. Transcripts of five inquiries conducted between 1998 and 2003 were analysed using critical discourse analysis. The findings revealed two dominant discourses that were drawn upon in the inquiries to construct nurses' conduct as unethical. These were discourses of trust and accountability. The way the nurses were spoken about during the inquiries was shaped by normalising judgements that were used to discursively position the nurse through narrative.

This study aims to develop multimedia learning based inquiry that is interesting, easy to understand by students and streamline the time of teachers in bringing the teaching materials as well as feasible to be used in learning the physics subject matter of vibration and wave. This research is a Research and Development research with reference to ADDIE model that is Analysis, Design, Development, Implementation, and Evaluation. Multimedia based learning inquiry is packaged in hypertext form using Adobe Flash CS6 Software. The inquiry aspect is constructed by showing the animation of the concepts that the student wants to achieve and then followed by questions that will ask the students what is observable. Multimedia learning based inquiry is then validated by 2 learning experts, 3 material experts and 3 media experts and tested on 3 junior high school teachers and 23 students of state junior high school 5 of Kendari. The results of the study include: (1) Validation results by learning experts, material experts and media experts in valid categories; (2) The results of trials by teachers and students fall into the practical category. These results prove that the multimedia learning based inquiry on vibration and waves materials that have been developed feasible use in physics learning by students of junior high school class VIII.

A Subdivision-Based Representation for Vector Image Editing.

Liao, Zicheng; Hoppe, Hugues; Forsyth, David; Yu, Yizhou

2012-11-01

Vector graphics has been employed in a wide variety of applications due to its scalability and editability. Editability is a high priority for artists and designers who wish to produce vector-based graphical content with user interaction. In this paper, we introduce a new vector image representation based on piecewise smooth subdivision surfaces, which is a simple, unified and flexible framework that supports a variety of operations, including shape editing, color editing, image stylization, and vector image processing. These operations effectively create novel vector graphics by reusing and altering existing image vectorization results. Because image vectorization yields an abstraction of the original raster image, controlling the level of detail of this abstraction is highly desirable. To this end, we design a feature-oriented vector image pyramid that offers multiple levels of abstraction simultaneously. Our new vector image representation can be rasterized efficiently using GPU-accelerated subdivision. Experiments indicate that our vector image representation achieves high visual quality and better supports editing operations than existing representations.

Primary Teachers' Reflections on Inquiry- and Context-Based Science Education

Walan, Susanne; Mc Ewen, Birgitta

2017-04-01

Inquiry- and context-based teaching strategies have been proven to stimulate and motivate students' interests in learning science. In this study, 12 teachers reflected on these strategies after using them in primary schools. The teachers participated in a continuous professional development (CPD) programme. During the programme, they were also introduced to a teaching model from a European project, where inquiry- and context-based education (IC-BaSE) strategies were fused. The research question related to teachers' reflections on these teaching strategies, and whether they found the model to be useful in primary schools after testing it with their students. Data collection was performed during the CPD programme and consisted of audio-recorded group discussions, individual portfolios and field notes collected by researchers. Results showed that compared with using only one instructional strategy, teachers found the new teaching model to be a useful complement. However, their discussions also showed that they did not reflect on choices of strategies or purposes and aims relating to students' understanding, or the content to be taught. Before the CPD programme, teachers discussed the use of inquiry mainly from the aspect that students enjoy practical work. After the programme, they identified additional reasons for using inquiry and discussed the importance of knowing why inquiry is performed. However, to develop teachers' knowledge of instructional strategies as well as purposes for using certain strategies, there is need for further investigations among primary school teachers.

Although nature of science (NOS) and nature of scientific inquiry (NOSI) are related to each other, they are differentiated as NOS is being more related to the product of scientific inquiry (SI) which is scientific knowledge whereas NOSI is more related to the process of SI (Schwartz et al. 2008). Lederman et al. (Journal of Research in Science Teaching, 51, 65-8, 2014) determined eight NOSI aspects for K-16 context. In this study, a science camp was conducted to teach scientific inquiry (SI) and NOSI to 24 6th and 7th graders (16 girls and 8 boys). The core of the program was guided inquiry in nature. The children working in small groups under guidance of science advisors conducted four guided-inquiries in the nature in morning sessions on nearby plants, animals, water, and soil. NOSI aspects were made explicit during and at the end of each inquiry session. Views about scientific inquiry (VASI) (Lederman et al. Journal of Research in Science Teaching, 51, 65-8, 2014) questionnaire was applied as pre- and post-test. The results of the study showed that children developed in all eight NOSI aspects, but higher developments were observed in "scientific investigations all begin with a question" and "there is no single scientific method," and "explanations are developed from data and what is already known" aspects. It was concluded that the science camp program was effective in teaching NOSI.

Data-driven Inquiry in Environmental Restoration Studies

Zalles, D. R.; Montgomery, D. R.

Place-based field work has been recognized as an important component of geoscience education programs for engaging students. Field work helps students appreciate the spatial extent of data and the systems operating in a locale. Data collected in a place has a temporal aspect that can be explored through representations such as photographs and maps and also though numerical data sets that capture characteristics of place. Yet, experiencing authentic geoscience research in an educational setting requires going beyond fieldwork: students must develop data literacy skills that will enable them to connect abstract representations of spatio-temporal data with place. Educational researchers at SRI International led by Dr. Daniel Zalles, developer of inquiry-based geoscience curricula, and geoscientists at the University of Washington (UW) led by Dr. David Montgomery, Professor of Earth and Space Sciences, are building educational curriculum modules that help students make these connections. The modules concern the environmental history of the Puget Sound area in Washington State and its relevance for the American Indians living there. This collaborative project relies on environmental data collected in the Puget Sound Regional Synthesis Model (PRISM) and Puget Sound River History Project. The data sets are being applied to inquiry-based geoscience investigations at the undergraduate and high school level. The modules consist of problem-based units centered on the data sets, plus geographic and other data representations. The modules will rely on educational "design patterns" that characterize geoscientific inquiry tasks. Use of design patterns will enable other modules to be built that align to the modes of student thinking and practice articulated in the design patterns. The modules will be accompanied by performance assessments that measure student learning from their data investigations. The design principles that drive this project have already been used effectively

Global Bathymetry: Machine Learning for Data Editing

Science.gov (United States)

Sandwell, D. T.; Tea, B.; Freund, Y.

2017-12-01

The accuracy of global bathymetry depends primarily on the coverage and accuracy of the sounding data and secondarily on the depth predicted from gravity. A main focus of our research is to add newly-available data to the global compilation. Most data sources have 1-12% of erroneous soundings caused by a wide array of blunders and measurement errors. Over the years we have hand-edited this data using undergraduate employees at UCSD (440 million soundings at 500 m resolution). We are developing a machine learning approach to refine the flagging of the older soundings and provide automated editing of newly-acquired soundings. The approach has three main steps: 1) Combine the sounding data with additional information that may inform the machine learning algorithm. The additional parameters include: depth predicted from gravity; distance to the nearest sounding from other cruises; seafloor age; spreading rate; sediment thickness; and vertical gravity gradient. 2) Use available edit decisions as training data sets for a boosted tree algorithm with a binary logistic objective function and L2 regularization. Initial results with poor quality single beam soundings show that the automated algorithm matches the hand-edited data 89% of the time. The results show that most of the information for detecting outliers comes from predicted depth with secondary contributions from distance to the nearest sounding and longitude. A similar analysis using very high quality multibeam data shows that the automated algorithm matches the hand-edited data 93% of the time. Again, most of the information for detecting outliers comes from predicted depth secondary contributions from distance to the nearest sounding and longitude. 3) The third step in the process is to use the machine learning parameters, derived from the training data, to edit 12 million newly acquired single beam sounding data provided by the National Geospatial-Intelligence Agency. The output of the learning algorithm will be

Impact of backwards faded scaffolding approach to inquiry-based astronomy laboratory experiences on undergraduate non-science majors' views of scientific inquiry

Science.gov (United States)

Lyons, Daniel J.

This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of

Genome Editing: A New Approach to Human Therapeutics.

Porteus, Matthew

2016-01-01

The ability to manipulate the genome with precise spatial and nucleotide resolution (genome editing) has been a powerful research tool. In the past decade, the tools and expertise for using genome editing in human somatic cells and pluripotent cells have increased to such an extent that the approach is now being developed widely as a strategy to treat human disease. The fundamental process depends on creating a site-specific DNA double-strand break (DSB) in the genome and then allowing the cell's endogenous DSB repair machinery to fix the break such that precise nucleotide changes are made to the DNA sequence. With the development and discovery of several different nuclease platforms and increasing knowledge of the parameters affecting different genome editing outcomes, genome editing frequencies now reach therapeutic relevance for a wide variety of diseases. Moreover, there is a series of complementary approaches to assessing the safety and toxicity of any genome editing process, irrespective of the underlying nuclease used. Finally, the development of genome editing has raised the issue of whether it should be used to engineer the human germline. Although such an approach could clearly prevent the birth of people with devastating and destructive genetic diseases, questions remain about whether human society is morally responsible enough to use this tool.

Assiri, Yahya Ibrahim

This study investigated elementary science teachers' knowledge, beliefs, values, and concerns of teaching through inquiry. A mixed-methods research design was utilized to address the research questions. Since this study was designed as a mixed-methods research approach, the researcher gathered two type of data: quantitative and qualitative. The study was conducted in Mohayel School District, Saudi Arabia. The information was collected from 51 participants using a questionnaire with multiple choice questions; also, 11 participants were interviewed. After collecting the data, descriptive and comparative approaches were used. In addition, themes and codes were used to obtain the results. The results indicated that the mean of elementary science teachers' knowledge was 51.23%, which was less than 60% which was the acceptable score. Also, the qualitative results showed that science teachers had a limited background of teaching through inquiry. In addition, the elementary science teachers had a high level of belief to teach science through inquiry since the mean was 3.99 out of 5.00. These quantitative results were confirmed by the qualitative data. Moreover, the overall mean of elementary science teachers was 4.01, which indicated that they believed in the importance of teaching science through inquiry which was also confirmed by the responses of teachers in the interviews. Also, the findings indicated that elementary school science teachers had concerns about teaching science through inquiry since the overall mean was 3.53. In addition, the interviewees mentioned that they faced some obstacles when they teach by inquiry, such as time, resources, class size, and the teachers' background. Generally, the results did not show any significant differences among elementary science teachers' knowledge, beliefs, values, and concerns depending on gender, level of education, and teaching experience. However, the findings indicated there was one significant difference which was
