with the clinical presentation, biochemistry, and pathology of this disorder. To the author's knowledge this is the only plausible and self-consistent mechanism to explain CICI. These two different disorders of the CNS affect millions of persons worldwide. Both AD and CICI share free radical-mediated oxidative stress in brain, but the source of oxidative stress is not the same. Continued research is necessary to better understand both AD and CICI. The discoveries about these disorders from the Butterfield laboratory that led to the 2013 Discovery Award from the Society of Free Radical and Medicine provides a significant foundation from which this future research can be launched.

Topos models for physics and topos theory

International Nuclear Information System (INIS)

Wolters, Sander

2014-01-01

What is the role of topos theory in the topos models for quantum theory as used by Isham, Butterfield, Döring, Heunen, Landsman, Spitters, and others? In other words, what is the interplay between physical motivation for the models and the mathematical framework used in these models? Concretely, we show that the presheaf topos model of Butterfield, Isham, and Döring resembles classical physics when viewed from the internal language of the presheaf topos, similar to the copresheaf topos model of Heunen, Landsman, and Spitters. Both the presheaf and copresheaf models provide a “quantum logic” in the form of a complete Heyting algebra. Although these algebras are natural from a topos theoretic stance, we seek a physical interpretation for the logical operations. Finally, we investigate dynamics. In particular, we describe how an automorphism on the operator algebra induces a homeomorphism (or isomorphism of locales) on the associated state spaces of the topos models, and how elementary propositions and truth values transform under the action of this homeomorphism. Also with dynamics the focus is on the internal perspective of the topos

In this chapter we describe how we, as researchers, interacted with practitioners in the field as we co-constructed a polyphonic inquiry for team development, learning and knowledge production, inspired by action research. We build on social constructionist meta-theoretical ideas and write about...... our experience from a constructionist approach to research and social change. Our practice was developed and refined while working together with a team of advisers in an NGO for organic farming and organic food production located in Denmark. In overall terms, and in line with the values...... of the organization, a basic principle of this practice was to think and work in terms of sustainability, environmental care, and social responsibility.

2018-01-01

Our different kinds of minds and types of thinking affect the ways we decide, take action, and cooperate (or not). The comment by Walker et al. (2018, https://doi.org/10.1002/2017EF000750) illustrates several points made by Glynn et al. (2017, https://doi.org/10.1002/2016EF000487) and many other articles. Namely, biases and beliefs often drive scientific reasoning, and scientists, just like other humans, are intimately attached to their values and heuristics. Scientists, just like many other people, also tend to read and interpret text in ways that best match their individual perceptions of a problem or issue: in many cases paraphrasing and changing the meaning of what they read to better match their initial ideas. Walker et al. are doing interesting and important research on uncertainty. Nonetheless, they misinterpret the work, assumptions, and conclusions brought forth by Glynn et al. (2017, https://doi.org/10.1002/2016EF000487).

Design, revision, and application of ground-water flow models for simulation of selected water-management scenarios in the coastal area of Georgia and adjacent parts of South Carolina and Florida

Science.gov (United States)

Clarke, John S.; Krause, Richard E.

2000-01-01

Ground-water flow models of the Floridan aquifer system in the coastal area of Georgia and adjacent parts of South Carolina and Florida, were revised and updated to ensure consistency among the various models used, and to facilitate evaluation of the effects of pumping on the ground-water level near areas of saltwater contamination. The revised models, developed as part of regional and areal assessments of ground-water resources in coastal Georgia, are--the Regional Aquifer-System Analysis (RASA) model, the Glynn County area (Glynn) model, and the Savannah area (Savannah) model. Changes were made to hydraulic-property arrays of the RASA and Glynn models to ensure consistency among all of the models; results of theses changes are evidenced in revised water budgets and calibration statistics. Following revision, the three models were used to simulate 32 scenarios of hypothetical changes in pumpage that ranged from about 82 million gallons per day (Mgal/d) lower to about 438 Mgal/d higher, than the May 1985 pumping rate of 308 Mgal/d. The scenarios were developed by the Georgia Department of Natural Resources, Environmental Protection Division and the Chatham County-Savannah Metropolitan Planning Commission to evaluate water-management alternatives in coastal Georgia. Maps showing simulated ground-water-level decline and diagrams presenting changes in simulated flow rates are presented for each scenario. Scenarios were grouped on the basis of pumping location--entire 24-county area, central subarea, Glynn-Wayne-Camden County subarea, and Savannah-Hilton Head Island subarea. For those scenarios that simulated decreased pumpage, the water level at both Brunswick and Hilton Head Island rose, decreasing the hydraulic gradient and reducing the potential for saltwater contamination. Conversely, in response to scenarios of increased pumpage, the water level at both locations declined, increasing the hydraulic gradient and increasing the potential for saltwater contamination

The paper contains a relatively non-technical summary of some recent work by the author and Jeremy Butterfield. The goal is to find a way of assigning meaningful truth values to propositions in quantum theory: something that is not possible in the normal, instrumentalist interpretation. The key mathematical tool is presheaf theory where multi-valued, contextual truth values arise naturally. We show how this can be applied to quantum theory, with the ‘contexts’ chosen to be Boolean subalgebras of the set of all projection operators.

Sheila served as Editor of the Journal of Helminthology from 1980 to 1986.Dr Lotfi Khalil, formerly Deputy Director of the International Institute of Parasitology at St Albans, worked closely with Sheila and has written the following tribute.John W. Lewis, EditorSheila Willmott was a leading contributor to the dissemination of parasitic information before the development of computerization and information technology. She was born on 8 June, 1921, in London, and was educated at Tollington High School for Girls, Chelsea Polytechnic and University College, London. She did her PhD at the London School of Hygiene and Tropical Medicine under the supervision of Professor John Buckley, the subject of her thesis being the study of amphistome digeneans. Her studies were interrupted as a result of the Second World War when she was 'drafted' as a Rodent Instructor at the Ministry of Agriculture, Fisheries and Food. After completing her PhD, she was appointed Assistant Lecturer in Zoology at the University College of South Wales and Monmouthshire, Cardiff. In 1951, Professor R.T. Leiper, the Director of the Bureau of Agricultural Parasitology (Helminthology) recruited her as a Scientific Information Officer. She was appointed Assistant Director of the Bureau in 1954, and Director in 1961, where she stayed until her retirement in 1980.During her period as Director of the Bureau, which was sited in the White House in the centre of St Albans, she maintained and improved the high quality of Helminthological Abstracts and, in 1976, accepted the extra burden of starting and producing Protozoological Abstracts. In 1979, she initiated and edited a primary journal, Systematic Parasitology, devoted to papers on the taxonomy

Families and the European Union : law, politics and pluralism.

OpenAIRE

McGlynn, C.M.S.

2006-01-01

In the first book to offer a comprehensive analysis of family law in the European Union, McGlynn argues that a traditional concept of 'family' which has many adverse effects - on individuals, on families (in all their diverse forms), and indeed on the economic ambitions of the EU is forming the basis for the little-recognised and under-researched field of EU family law. This book examines three different aspects of family life - childhood, parenthood and partnerships - and critically analyses...

A holistic strategy for adaptive land management

Science.gov (United States)

Herrick, Jeffrey E.; Duniway, Michael C.; Pyke, David A.; Bestelmeyer, Brandon T.; Wills, Skye A.; Brown, Joel R.; Karl, Jason W.; Havstad, Kris M.

2012-01-01

Adaptive management is widely applied to natural resources management (Holling 1973; Walters and Holling 1990). Adaptive management can be generally defined as an iterative decision-making process that incorporates formulation of management objectives, actions designed to address these objectives, monitoring of results, and repeated adaptation of management until desired results are achieved (Brown and MacLeod 1996; Savory and Butterfield 1999). However, adaptive management is often criticized because very few projects ever complete more than one cycle, resulting in little adaptation and little knowledge gain (Lee 1999; Walters 2007). One significant criticism is that adaptive management is often used as a justification for undertaking actions with uncertain outcomes or as a surrogate for the development of specific, measurable indicators and monitoring programs (Lee 1999; Ruhl 2007).

2007-01-01

August 7, 2006 the state of Georgia conducted a collaborative sampling exercise between the Georgia National Guard 4th Civil Support Team Weapons of Mass Destruction (CST-WMD) and the Georgia Department of Human Resources Division of Public Health demonstrating a recently validated bulk powder sampling method. The exercise was hosted at the Federal Law Enforcement Training Center (FLETC) at Glynn County, Georgia and involved the participation of the Georgia Emergency Management Agency (GEMA), Georgia National Guard, Georgia Public Health Laboratories, the Federal Bureau of Investigation Atlanta Office, Georgia Coastal Health District, and the Glynn County Fire Department. The purpose of the exercise was to demonstrate a recently validated national sampling standard developed by the American Standards and Test Measures (ASTM) International; ASTM E2458 S tandard Practice for Bulk Sample Collection and Swab Sample Collection of Visible Powders Suspected of Being Biological Agents from Nonporous Surfaces . The intent of the exercise was not to endorse the sampling method, but to develop a model for exercising new sampling methods in the context of existing standard operating procedures (SOPs) while strengthening operational relationships between response teams and analytical laboratories. The exercise required a sampling team to respond real-time to an incident cross state involving a clandestine bio-terrorism production lab found within a recreational vehicle (RV). Sample targets consisted of non-viable gamma irradiated B. anthracis Sterne spores prepared by Dugway Proving Ground. Various spore concentration levels were collected by the ASTM method, followed by on- and off-scene analysis utilizing the Center for Disease Control (CDC) Laboratory Response Network (LRN) and National Guard Bureau (NGB) CST mobile Analytical Laboratory Suite (ALS) protocols. Analytical results were compared and detailed surveys of participant evaluation comments were examined. I will

Full Text Available Objective – To examine the development of information literacy (IL strategies in higher education by assessing content and presentation of IL strategy documentation, and to explore the application of corporate strategy concepts and techniques to IL strategy.Design – Comparative, multi-case study. Qualitative analysis.Setting – U.K. universities.Subjects – Twelve information literacy strategy documents from ten institutions.Methods – Google was searched for IL strategy documents (restricted to the ac.uk domain, the LISINFOLITERACY discussion list was queried, and the Web sites of all U.K. universities were searched for a total sample of 12 documents at 10 institutions. Results of the data capture were discussed in the context of the literature on strategic management.Main Results – Corporate strategy tools and techniques are extensive in the literature, trending toward an emphasis on holistic thinking and marketing concepts. Many themes identified in the documents were consistent with the literature. While the format and style varied, all documents emphasized the integration of IL into subject curricula. All stressed the need to build collaborative partnerships between library/information staff and academic staff.Significantly, many strategies aimed to reach the broader institution, although poor articulation undermined this ambitious goal. In three, IL intervention was intended for the whole university community. However, the target audience often was not well-defined. Seven of the IL strategies identified additional partnerships to effect change at the policy level. Another key theme was the adoption of recognized IL standards; seven proposed the SCONUL (1999 model. All strategies recognized the importance of learning outcomes; six stated them explicitly. Prominent was the integration of e-learning resources, namely online tutorials. Many strategies recognized the need for marketing and advocacy activities. Half considered professional or staff development issues, as supported in the literature. All strategies explained in detail the context of their IL proposals, citing external challenges (growth of digital information, employer demand, external evidence (official reports, benchmarking statements, studies, and internal evidence (stakeholder concerns, institutional strategies to support the need for IL. The documents specified a range of teaching modes from informal reference desk encounters to strategic positioning in relation to the broader community. Half defined or described IL. Seven documents were labelled strategies, but many did not comply with content elements defined in the literature. Other features of the literature poorly represented in the documents included: the need for well articulated objectives, mission and vision statements, attendance to broader strategic issues,stakeholder analysis, and the prioritizing of IL activities with portfolio development. Only two had action plans. Seven documents were in the public domain. Conclusion – Information literacy is recognized as an essential competence for participation in higher education, the workplace and society, and information professionals have long promoted IL. In response to the changing information environment they have sought to formalize policies and strategies to embed IL institutionally, working collaboratively with key stakeholders in the process. In this study of strategic documentation from 10 U.K. universities, IL objectives were consistent although the format and style of documentation varied. The author concludes that one or more strategic management models or tools available could improve IL strategy development, consistency, and coherency. Most importantly, an overarching strategic management framework should be used to resolve ambiguity and inconsistency, improve articulation, and maximize the effectiveness of strategy documents, thus avoiding weaknesses identified in the study. As noted by the author, the library literature has progressed to include strategic management concepts evidenced, in part, by the number of libraries using Kaplan and Norton’s scorecard system. But improvements can be made: conforming to strategic planning norms could strengthen IL strategy. Elements of models from the public or private sectors might be tailored to meet the specific needs of IL strategies. Further research could identify suitable strategy models for IL development. The process of implementing IL strategy should also be considered in future research. The author notes it would be interesting to explore the relationship between IL strategies and other organizational strategies and to compare IL strategies inother sectors.

This article illustrates how intertextual reading helped to clarify the poem. Teresa of Avila’s The way of perfection (a translation of the Spanish work El Camino de la Perfección, 1573 is the intertext of the Van Wyk Louw poem. In the last section of the article it is shown how the figure of St. Teresa of Avila is central not only to Van Wyk Louw’s Tristia (1962, but also to the oeuvre of Sheila Cussons, which underlines a strong intertextuality between these two Afrikaans oeuvres.

Beyond evidence: a critical appraisal of global warming as a socio-scientific issue and a reflection on the changing nature of scientific literacy in school

Science.gov (United States)

Colucci-Gray, L.

2014-09-01

Tom G. K. Bryce and Stephen P. Day's (2013) original article on scepticism and doubt in science education explores the context of citizens' attitudes towards the complexities and uncertainties of global issues, namely global warming. This response aims to stimulate reflection on some of the implicit assumptions underpinning the relationships between science, technology and the public. I argue that an underestimation of the political and ethical dimensions of science and technology limits the possibilities for education to set the agenda for citizens' participation in science and technological matters. Drawing on Sheila Jasanoff's model of co-production, this paper proposes a radical re-affirmation of the aims and purposes of science education to embrace a multiplicity of disciplines, narratives and ways of knowing in science, technology and society issues.

Had We But World Enough, and Time... But We Don't!: Justifying the Thermodynamic and Infinite-Time Limits in Statistical Mechanics

Science.gov (United States)

Palacios, Patricia

2018-05-01

In this paper, I compare the use of the thermodynamic limit in the theory of phase transitions with the infinite-time limit in the explanation of equilibrium statistical mechanics. In the case of phase transitions, I will argue that the thermodynamic limit can be justified pragmatically since the limit behavior (i) also arises before we get to the limit and (ii) for values of N that are physically significant. However, I will contend that the justification of the infinite-time limit is less straightforward. In fact, I will point out that even in cases where one can recover the limit behavior for finite t, i.e. before we get to the limit, one cannot recover this behavior for realistic time scales. I will claim that this leads us to reconsider the role that the rate of convergence plays in the justification of infinite limits and calls for a revision of the so-called Butterfield's principle.

Studies of drift waves in a toroidal heliac

International Nuclear Information System (INIS)

Shi, X.H.; Blackwell, B.D.; Hamberger, S.M.

1989-01-01

Low frequency, coherent density fluctuations have been studied for three typical magnetic configurations in the helical axis stellarator SHEILA using Langmuir probe techniques. The parametric dependence, the threshold magnetic field, the frequency spectrum and the spatial structure of the fluctuations are measured experimentally. Mode analyses are made in a magnetic coordinate system. Both the mode numbers thus obtained and the smallness of the directly measured values of the wavenumber along the magnetic field lines indicate a close correspondence between the helicity of the fluctuations and the field lines. These experimental results are consistent with a collisional drift wave model, derived from a linearized two-fluid theory, related to the heliac geometry. Density reduction associated with the fluctuations is clearly observed and is consistent with rough estimates of the cross-filed particle flux due to the fluctuations. 17 refs., 18 figs., 1 tab

The scholar as craftsman: Derek de Solla Price and the reconstruction of a medieval instrument.

Science.gov (United States)

Falk, Seb

2014-06-20

The Royal Society Conversaziones were biannual social evenings at which distinguished guests could learn about the latest scientific developments. The Conversazione in May 1952 featured an object that came to be called King Arthur's Table. It was a planetary equatorium, made in Cambridge's Cavendish Laboratory at the behest of Sir Lawrence Bragg. Conceived by the historian of science Derek de Solla Price as a huge, tangible realization of Chaucerian astronomy, it was displayed at the new Whipple Museum of the History of Science, discarded, stored incognito, catalogued with that whimsical name, and finally re-identified in 2012. This article examines the biography of that object and, through it, the early, inchoate years of the discipline of history of science in Cambridge. The process of disciplinary establishment involved a range of actors beyond well-known figures such as Herbert Butterfield and Joseph Needham; the roles of Price and Bragg are highlighted here. Study of these individuals, and of the collaboration that brought about the reconstruction, reveals much about the establishment of a discipline, as well as changing scholarly and curatorial attitudes towards replicas.

The original version from Emde, Osofsky & Butterfield (1993 was developed in the United States and involves 30 stimuli. The Peruvian version involves 25 pictures of children with prototypic facial features of the majority of Peruvian population. A sample of 363 men and women of middle and low socio-economic status between 19 and 45 years old was recruited to develop the Peruvian version. From the results, a lexicon was created with the words that were used by the participants to designate the 14 groups of emotion that were obtained. The majority of these groups had an adequate reliability for temporal stability. Finally, it was found that the socio-economic status (SES is a variable that generates significant differences in the way how persons interpret the emotions. Therefore, referential values of differentiated interpretation were created from this variable.

Dreamscapes of modernity sociotechnical imaginaries and the fabrication of power

Kim, Sang-Hyun

2015-01-01

Dreamscapes of Modernity offers the first book-length treatment of sociotechnical imaginaries, a concept originated by Sheila Jasanoff and developed in close collaboration with Sang-Hyun Kim to describe how visions of scientific and technological progress carry with them implicit ideas about public purposes, collective futures, and the common good. The book presents a mix of case studies-including nuclear power in Austria, Chinese rice biotechnology, Korean stem cell research, the Indonesian Internet, US bioethics, global health, and more-to illustrate how the concept of sociotechnical imaginaries can lead to more sophisticated understandings of the national and transnational politics of science and technology. A theoretical introduction sets the stage for the contributors' wide-ranging analyses, and a conclusion gathers and synthesizes their collective findings. The book marks a major theoretical advance for a concept that has been rapidly taken up across the social sciences and promises to become central to...

Lévy matters V functionals of Lévy processes

Andersen, Lars Nørvang; Aurzada, Frank; Glynn, Peter W; Maejima, Makoto; Pihlsgård, Mats; Simon, Thomas

2015-01-01

This three-chapter volume concerns the distributions of certain functionals of Lévy processes. The first chapter, by Makoto Maejima, surveys representations of the main sub-classes of infinitesimal distributions in terms of mappings of certain Lévy processes via stochastic integration. The second chapter, by Lars Nørvang Andersen, Søren Asmussen, Peter W. Glynn and Mats Pihlsgård, concerns Lévy processes reflected at two barriers, where reflection is formulated à la Skorokhod. These processes can be used to model systems with a finite capacity, which is crucial in many real life situations, a most important quantity being the overflow or the loss occurring at the upper barrier.  If a process is killed when crossing the boundary, a natural question concerns its lifetime. Deep formulas from fluctuation theory are the key to many classical results, which are reviewed in the third chapter by Frank Aurzada and Thomas Simon. The main part, however, discusses recent advances and developments in the setting w...

The role of direct-to-consumer pharmaceutical advertisements and individual differences in getting people to talk to physicians.

Science.gov (United States)

Krezmien, Elyse; Wanzer, Melissa Bekelja; Servoss, Timothy; LaBelle, Sara

2011-09-01

In this study, 384 respondents provided quantitative and descriptive information about direct-to-consumer (DTC) pharmaceutical advertisements and factors related to message reception and drug adoption. The authors applied M. Booth-Butterfield's ( 2008 ) Standard Model to explain how DTC advertising is used in getting individuals to talk to their doctors about pharmaceutical drugs. The researchers predicted that individuals who talked with their physicians about a pharmaceutical drug (referred to as talkers) would differ from those who did not talk with their physicians (referred to as nontalkers) in a number of meaningful ways. Findings from this data set indicate that individuals who talked with their physician about a specific medication were more likely to be female, older, higher in need for cognition, and reported higher physician satisfaction. Total number of channels (TV, radio, newspaper, magazines, and the Internet) was negatively associated with talking to a physician about a specific medication, as was exposure to DTC advertisement on television. The authors offer explanations for these findings along with descriptive accounts of how talkers and nontalkers differed in their recall of DTC advertisement information.

Secondly, I question whether the demand for “normality” entails the creation of new exclusions (following Judith Butler’s approach to normality: Finally, I consider whether camp culture reproduces and/or subverts gender rules (introducing a discussion between Sheila Jeffreys and Judith Butler’s positions. On the basis of this exploration of Mira's three cultural models, I develop a typology of political positions ('normalization of homosexuality', 'transformation' and 'queer', which I apply to the case study of the Catalan lesbian and gay movement.

These guidelines are an official statement of the American Speech-Language-Hearing Association. They provide guidance on the training, credentialing, use, and supervision of one category of support personnel in speech-language pathology: speech-language pathology assistants. Guidelines are not official standards of the Association. They were developed by the Task Force on Support Personnel: Dennis J. Arnst, Kenneth D. Barker, Ann Olsen Bird, Sheila Bridges, Linda S. DeYoung, Katherine Formichella, Nena M. Germany, Gilbert C. Hanke, Ann M. Horton, DeAnne M. Owre, Sidney L. Ramsey, Cathy A. Runnels, Brenda Terrell, Gerry W. Werven, Denise West, Patricia A. Mercaitis (consultant), Lisa C. O'Connor (consultant), Frederick T. Spahr (coordinator), Diane Paul-Brown (associate coordinator), Ann L. Carey (Executive Board liaison). The 1994 guidelines supersede the 1981 guidelines entitled, "Guidelines for the Employment and Utilization of Supportive Personnel" (Asha, March 1981, 165-169). Refer to the 1995 position statement on the "Training, Credentialing, Use, and Supervision of Support Personnel in Speech-Language Pathology" (Asha, 37 [Suppl. 14], 21).

The U.S. Geological Survey collects groundwater data and conducts studies to monitor hydrologic conditions, define groundwater resources, and address problems related to water supply, water use, and water quality. In Georgia, water levels were monitored continuously at 157 wells during calendar years 2015 and 2016. Because of missing data or short periods of record (less than 5 years) for several of these wells, data for 147 wells are presented in this report. These wells include 15 in the surficial aquifer system, 18 in the Brunswick aquifer system and equivalent sediments, 59 in the Upper Floridan aquifer, 13 in the Lower Floridan aquifer and underlying units, 9 in the Claiborne aquifer, 1 in the Gordon aquifer, 8 in the Clayton aquifer, 16 in the Cretaceous aquifer system, 2 in Paleozoic-rock aquifers, and 6 in crystalline-rock aquifers. Data from the well network indicate that water levels generally rose during the 10-year period from 2007 through 2016, with water levels rising in 105 wells and declining in 31 wells; insufficient data prevented determination of a 10-year trend in 11 wells. Water levels declined over the long-term period of record at 80 wells, increased at 62 wells, and remained relatively constant at 5 wells.In addition to continuous water-level data, periodic water-level data were collected and used to construct potentiometric-surface maps for the Upper Floridan aquifer in the Brunswick–Glynn County area during October 2015 and October 2016 and in the Albany–Dougherty County area during December 2015 and November and December 2016. Periodic water-level measurements were also collected and used to construct potentiometric-surface maps for the Cretaceous aquifer system in the Augusta–Richmond County area during July 2015 and June 2016. In general, water levels in the Upper Floridan aquifer were higher during 2015 than during 2016 in the Brunswick–Glynn County and Albany–Dougherty County areas due to higher precipitation during 2015

Possible words and fixed stress in the segmentation of Slovak speech.

The possible-word constraint (PWC; Norris, McQueen, Cutler, & Butterfield, 1997) has been proposed as a language-universal segmentation principle: Lexical candidates are disfavoured if the resulting segmentation of continuous speech leads to vowelless residues in the input-for example, single consonants. Three word-spotting experiments investigated segmentation in Slovak, a language with single-consonant words and fixed stress. In Experiment 1, Slovak listeners detected real words such as ruka "hand" embedded in prepositional-consonant contexts (e.g., /gruka/) faster than those in nonprepositional-consonant contexts (e.g., /truka/) and slowest in syllable contexts (e.g., /dugruka/). The second experiment controlled for effects of stress. Responses were still fastest in prepositional-consonant contexts, but were now slowest in nonprepositional-consonant contexts. In Experiment 3, the lexical and syllabic status of the contexts was manipulated. Responses were again slowest in nonprepositional-consonant contexts but equally fast in prepositional-consonant, prepositional-vowel, and nonprepositional-vowel contexts. These results suggest that Slovak listeners use fixed stress and the PWC to segment speech, but that single consonants that can be words have a special status in Slovak segmentation. Knowledge about what constitutes a phonologically acceptable word in a given language therefore determines whether vowelless stretches of speech are or are not treated as acceptable parts of the lexical parse.

Practical, effective methods that could be implemented in a food service establishment (restaurant or delicatessen) for the surface sanitization of cantaloupes were microbiologically evaluated. Cantaloupes (Cucumis melo L. var. reticulates) were immersed in an inoculum containing Salmonella enterica serovar Poona or Pantoea agglomerans at ca. 10(4) to 10(5) CFU/ml. An efficient method for the recovery of bacteria from the cantaloupe surface was developed and validated. The method consisted of washing the entire melon with Butterfield's buffer containing 1% Tween 80 in a plastic bag placed inside a plastic pail affixed to an orbital shaker. Levels of S. enterica Poona recovered by washing the entire melon were significantly higher than those recovered by the more common laboratory method of blending the rind. P. agglomerans can be used as a non-pathogenic proxy for S. enterica Poona. A three-compartment surface sanitization method consisting of washing with an antimicrobial soap solution, scrubbing with a brush in tap water, and immersion in 150 ppm of sodium hypochlorite reduced the initial level of recoverable viable bacteria by 99.8%. When examined separately, scrubbing with a vegetable brush in tap water, washing with soap, and dipping in chlorine were found to reduce the bacterial load by 70, 80, and 90%, respectively.

Full Text Available Sheila Krishnan, Jessica KileyDepartment of Obstetrics and Gynecology, Northwestern University, Chicago, Illinois, USAAbstract: Extended-cycle oral contraceptives (OCs are increasing in popularity in the United States. A new extended-cycle OC that contains the lowest doses of ethinyl estradiol (EE and levonorgestrel (LNG + continuous EE throughout the cycle is now available. It provides 84 days of a low-dose, combined active pill containing levonorgestrel 100 µg and ethinyl estradiol 20 µg. Instead of 7 days of placebo following the active pills, the regimen delivers 7 days of ethinyl estradiol 10 µg. Existing studies reveal a similar efficacy and adverse effect profile compared with other extended-regimen OCs. Specifically, the unscheduled bleeding profile is similar to other extended-cycle OCs and improves with the increase in the duration of use. Although lower daily doses of hormonal exposure have potential benefit, to our knowledge, there are no published studies indicating that this specific regimen offers a lower incidence of hormone-related side effects or adverse events. In summary, this new extended-cycle OC provides patients a low-dose, extended-regimen OC option without sacrificing efficacy or tolerability.Keywords: continuous regimen, ethinyl estradiol, extended cycle, oral contraceptive

For this purpose, 400 adults of A. cajenennse and 200 adults of A. dubitatum, plus 2,000 larvae and 2,000 nymphs of Amblyomma spp. were collected from horses and from the vegetation. The ticks were tested for rickettsial infection through polymerase chain reaction (PCR protocols targeting portions of three rickettsial genes (gltA, ompA, and ompB. Only two free-living A. cajennense adult ticks, and four pools of free-living Amblyomma spp. nymphs were shown to contain rickettsial DNA. PCR products from the two A. cajennense adult ticks were shown to be identical to corresponding sequences of the Rickettsia rickettsii strain Sheila Smith. DNA sequences of gltA-PCR products of the four nymph pools of Amblyomma spp. revealed a new genotype, which was shown to be closest (99.4% to the corresponding sequence of Rickettsia tamurae.

It is vital for the instructors and designers of the Massive Open Online Courses (MOOCs) to understand the motivation of its users for enrolling in the class and their reasons to engage with the material. This is particularly important for MOOCs focusing on scientific topics such as our MOOC on Astronomy (Astronomy: Exploring time and space) whose audience is less motivated by a desire to advance their careers compared to other MOOCs. In order to learn more about the motivation of our learners we deployed in our Astronomy MOOC a survey based on the Science Motivation Questionnaire II developed by Glynn et. al (2011). We specifically asked for reasons to sign up for the course and the overall motivation and attitude towards astronomy and science courses. We compare results of 3360 participants of this survey with a similar instrument administered to 638 students in undergraduate Astronomy classes for non Astronomy majors at the University of Arizona. Our comparison not only looks at the demographic differences, but also at reasons for signing up for the course and scores in motivational categories such as self-determination, self-efficacy, grade motivation, career motivation, hobby motivation, social motivation, and intrinsic motivation showing, that these populations of learners are fundamentally different.

The Physiologically based pharmacokinetic (PBPK) modeling is a supporting tool in drug discovery and improvement. Simulations produced by these models help to save time and aids in examining the effects of different variables on the pharmacokinetics of drugs. For this purpose, Sheila and Peters suggested a PBPK model capable of performing simulations to study a given drug absorption. There is a need to extend this model to the whole body entailing all another process like distribution, metabolism, and elimination, besides absorption. The aim of this scientific study is to hypothesize a WB-PBPK model through integrating absorption, distribution, metabolism, and elimination processes with the existing PBPK model.Absorption, distribution, metabolism, and elimination models are designed, integrated with PBPK model and validated. For validation purposes, clinical records of few drugs are collected from the literature. The developed WB-PBPK model is affirmed by comparing the simulations produced by the model against the searched clinical data. . It is proposed that the WB-PBPK model may be used in pharmaceutical industries to create of the pharmacokinetic profiles of drug candidates for better outcomes, as it is advance PBPK model and creates comprehensive PK profiles for drug ADME in concentration-time plots.

Current and potential ant impacts in the Pacific region

Loope, Lloyd L.; Krushelnycky, Paul D.

2007-01-01

Worldwide, ants are a powerful ecological force, and they appear to be dominant components of animal communities of many tropical and temperate ecosystems in terms of biomass and numbers of individuals (Bluthgen et al. 2000). For example, ants comprise up to 94% of arthropod individuals in fogging samples taken from diverse lowland tropical rainforest canopies, and 86% of the biomass (Davidson et al. 2003). The majority of these ant species and individuals obtain carbohydrates either from extrafloral nectaries or from sap-feeding Hemiptera that pass carbohydrate-rich “honeydew” to attending ants while concentrating nitrogen (N) from N-poor plant sap (Davidson et al. 2003). Honeydew and nectar represent key resources for arboreal ant species, although most ant species are at least partly carnivorous or scavengers (Bluthgen et al. 2004). In contrast to most of the terrestrial world, the biotas of many Pacific islands evolved without ants. Whereas endemic ant species are found in New Zealand (ca. 10 spp.), Tonga (ca. 10 spp.), and Samoa (ca. 12 spp.), other islands of Polynesia and parts of Micronesia likely lack native ants (Wilson and Taylor 1967, Wetterer 2002, Wetterer and Vargo 2003). About 20 Indo-Australian and western Pacific ant species range to the east and north of Samoa, but it is unclear how many of these were transported there by humans at some time (Wilson and Taylor 1967). Most of the remainder of the ant species currently found on Pacific islands are widespread species that fall in the category of “tramp species,” dispersed by recent human commerce and generally closely tied to human activity and urban areas (Wilson and Taylor 1967, McGlynn 1999). In Pacific island situations, some of these tramp ant species are able to thrive beyond areas of human activity. Relatively few ant species have been successful invaders of native communities on continents, and these include most of the species that pose the greatest problems for Pacific islands

In hillslopes with soils characterized by deep regoliths, such as Ultisols,Oxisols, and Alfisols, interflow occurs episodically over impeding layers near and parallel to the soil surface such as low-conductivity B horizons (e.g.Newman et al., 1998; Buttle andMcDonald, 2002; Du et al., In Review), till layers (McGlynn et al., 1999; Bishop et al., 2004), hardpans (McDaniel et al., 2008), C horizons (Detty and McGuire, 2010), and permeable bedrock (Tromp van Meerveld et al., 2007). As perched saturation develops within and above these impeding but permeable horizons, flow moves laterally downslope, but the perched water also continues to percolate through the impeding horizon to the unsaturated soils and saprolite below. Perched water and solutes will eventually traverse the zone of perched saturation above the impeding horizon and then enter and percolate through the impeding horizon. In such flow situations, only lower hillslope segments with sufficient downslope travel distance will deliver water to the riparian zone within the time scale of a storm.farther up the slope, lateral flow within the zone of perched saturation. will act mainly to shift the point of percolation (location where a water packet leaves the downslope flow zone in the upper soil layer and enters the impeding layer) down the hillslope from the point of infiltration. In flatter parts of the hillslope or in areas with little contrast between the conductivities of the upper and impeding soil layers, lateral flow distances will be negligible.

Methods of legitimation: how ethics committees decide which reasons count in public policy decision-making.

Science.gov (United States)

Edwards, Kyle T

2014-07-01

In recent years, liberal democratic societies have struggled with the question of how best to balance expertise and democratic participation in the regulation of emerging technologies. This study aims to explain how national deliberative ethics committees handle the practical tension between scientific expertise, ethical expertise, expert patient input, and lay public input by explaining two institutions' processes for determining the legitimacy or illegitimacy of reasons in public policy decision-making: that of the United Kingdom's Human Fertilisation and Embryology Authority (HFEA) and the United States' American Society for Reproductive Medicine (ASRM). The articulation of these 'methods of legitimation' draws on 13 in-depth interviews with HFEA and ASRM members and staff conducted in January and February 2012 in London and over Skype, as well as observation of an HFEA deliberation. This study finds that these two institutions employ different methods in rendering certain arguments legitimate and others illegitimate: while the HFEA attempts to 'balance' competing reasons but ultimately legitimizes arguments based on health and welfare concerns, the ASRM seeks to 'filter' out arguments that challenge reproductive autonomy. The notably different structures and missions of each institution may explain these divergent approaches, as may what Sheila Jasanoff (2005) terms the distinctive 'civic epistemologies' of the US and the UK. Significantly for policy makers designing such deliberative committees, each method differs substantially from that explicitly or implicitly endorsed by the institution.

Creating Own Histories: Adolescent Girls In Mumbai’s Bastis Use Photography As A Tool Of Documentation And Advocacy

Full Text Available Expressing oneself is a fundamental right as enunciated in many international conventions and national constitutions. Expressing oneself, however, is subject to other factors, namely, one’s access to language, and means and platforms of expression. Marginalised groups have historically been kept away from gaining, as well as creating, knowledge and language. Breaking out of deprivation for marginalised groups requires having a reference framework of their own stories that are accessible to their own people, as well as visible to the rest of the world as legitimate history. As Sheila Rowbotham (1973 says, “in order to create an alternative, an oppressed group must at once shatter the self-reflecting world which encircles it and, at the same time, project its own image onto history.... All revolutionary movements create their own ways of seeing.” (p. 27 This paper seeks to show Vacha’s work with adolescent girls who purport to express themselves and document their perspectives through photography. Girls form one of the most marginalised sections of society, due to age and gender. Girls from deprived backgrounds contend with further disabilities of caste and class. Their perspectives are seldom part of the collective consciousness of their own communities, let alone enter mainstream discourses. Vacha uses photography as a useful tool for deprived girls to express and document their stories. Public exhibitions are used to take these images to a wider audience.

During the last 25 years, scientific experimental and clinical studies have documented the dangers of cornstarch powder on examination and surgical gloves because the cornstarch promotes wound infection, causes serious peritoneal adhesions and granulomatous peritonitis, and is a well-documented vector of the latex allergy epidemic in the world. Realizing the dangers of cornstarch on examination and surgical gloves, Germany's regulations of personal protective equipment banned the use of surgical glove powder cornstarch in 1997. In 2000, the Purchasing and Supply agency for the United Kingdom ceased to purchase any gloves lubricated with cornstarch. Realizing the dangers of cornstarch-powdered gloves, many hospitals and clinics in the United States have banned the use of cornstarch-powdered examination and surgical gloves. Hospitals that have banned cornstarch in their examination and surgical gloves have noted a marked reduction in the latex allergy epidemic in their facilities. Realizing the dangers of cornstarch-powdered examination and surgical gloves, Dr Sheila A. Murphey, branch chief, Infection Control Devices Branch, Division of Anesthesiology, General Hospital, Infection Control, and Dental Devices Office of Device Evaluation, Center for Devices and Radiological Health of the Food and Drug Administration (FDA), recommended that a Citizen's Petition be filed to the FDA to ban cornstarch on surgical and examination gloves. The 12 authors of this report have attached the enclosed petition to the FDA to ban the use of cornstarch on all synthetic and latex examination and surgical gloves used in the United States.

This meta-analysis examined the extent to which stereotypes of leaders are culturally masculine. The primary studies fit into 1 of 3 paradigms: (a) In Schein's (1973) think manager-think male paradigm, 40 studies with 51 effect sizes compared the similarity of male and leader stereotypes and the similarity of female and leader stereotypes; (b) in Powell and Butterfield's (1979) agency-communion paradigm, 22 studies with 47 effect sizes compared stereotypes of leaders' agency and communion; and (c) in Shinar's (1975) masculinity-femininity paradigm, 7 studies with 101 effect sizes represented stereotypes of leadership-related occupations on a single masculinity-femininity dimension. Analyses implemented appropriate random and mixed effects models. All 3 paradigms demonstrated overall masculinity of leader stereotypes: (a) In the think manager-think male paradigm, intraclass correlation = .25 for the women-leaders similarity and intraclass correlation = .62 for the men-leaders similarity; (b) in the agency-communion paradigm, g = 1.55, indicating greater agency than communion; and (c) in the masculinity-femininity paradigm, g = 0.92, indicating greater masculinity than the androgynous scale midpoint. Subgroup and meta-regression analyses indicated that this masculine construal of leadership has decreased over time and was greater for male than female research participants. In addition, stereotypes portrayed leaders as less masculine in educational organizations than in other domains and in moderate- than in high-status leader roles. This article considers the relation of these findings to Eagly and Karau's (2002) role congruity theory, which proposed contextual influences on the incongruity between stereotypes of women and leaders. The implications for prejudice against women leaders are also considered.

The students' motivation to learn basic sciences in health science curricula is poorly understood. The purpose of this study was to investigate the influence of different components of motivation (intrinsic motivation, self-determination, self-efficacy and extrinsic -career and grade- motivation) on learning human histology in health science curricula and their relationship with the final performance of the students in histology. Glynn Science Motivation Questionnaire II was used to compare students' motivation components to learn histology in 367 first-year male and female undergraduate students enrolled in medical, dentistry and pharmacy degree programs. For intrinsic motivation, career motivation and self-efficacy, the highest values corresponded to medical students, whereas dentistry students showed the highest values for self-determination and grade motivation. Genders differences were found for career motivation in medicine, self-efficacy in dentistry, and intrinsic motivation, self-determination and grade motivation in pharmacy. Career motivation and self-efficacy components correlated with final performance in histology of the students corresponding to the three curricula. Our results show that the overall motivational profile for learning histology differs among medical, dentistry and pharmacy students. This finding is potentially useful to foster their learning process, because if they are metacognitively aware of their motivation they will be better equipped to self-regulate their science-learning behavior in histology. This information could be useful for instructors and education policy makers to enhance curricula not only on the cognitive component of learning but also to integrate students' levels and types of motivation into the processes of planning, delivery and evaluation of medical education.

Obituary: William K. Rose (1935-2010)

Stellar astrophysicist William Kenneth Rose died near his home in Potomac, Maryland, on September 30, 2010, after an extended illness. Rose was the son of pharmacist Kenneth William Rose and Shirley Near Rose and was born in Ossining, New York, on August 10, 1935. He received an AB from Columbia College in 1957 and a PhD in physics from Columbia University in 1963, with a thesis on "measurements of linear polarization in discrete radio sources using a 9.4 cm maser," under the direction of Charles H. Townes. Rose played a major role in designing and constructing the maser and used it at a radio telescope at Maryland Point that belonged to the Naval Research Lab. He observed Jupiter and Saturn and a number of extra-solar-system sources, and also diffuse centimeter emission (see appendix). The thesis was not published in an archival journal, but can be found under Library of Congress code QB 475.R67. While in graduate School, Bill married Sheila Tuchman, whose primary scientific interests were biological. None of their three children chose to be scientists, but two are CPAs. Bill moved successfully through the academic hurdles) from a research position at Princeton (1963-67), where a collaboration with Nick Woolf and Martin Schwarzchild on the infrared spectra of giant stars became one of his most-cited papers, to assistant and associate professorships at MIT (1967-71), and then associate and full professorships at the University of Maryland (1971 to retirement in 2005). His most innovative work was probably that on nova explosions arising from degenerate ignition of hydrogen accreted on white dwarfs in close binary systems, published in 1968. The same idea occurred to others at about the same time, and Bill did not, perhaps, get quite his fair share of the credit. I first met Sheila and Bill in summer 1969 at the Stony Brook summer school on stellar evolution (not published until 1972). He lectured on the nature of nova explosions and on nuclear burning in thin

Seawater bicarbonate removal during hydrothermal circulation

High temperature fluids sampled at hydrothermal vents represent a complex alteration product of water-rock reactions on a multi-component mixture of source fluids. Sources to high-temperature hydrothermal samples include the 'original' seawater present in the recharge limb of circulation, magmatically influenced fluids added at depth as well as any seawater entrained during sampling. High-temperature hydrothermal fluids are typically enriched in magmatic volatiles, with CO2 the dominant species, characterized by concentrations of 10's-100's of mmol/kg (1, 2). Typically, the high concentration of CO2 relative to background seawater bicarbonate concentrations (~2.3 mmol/kg) obscures a full analysis of the fate of seawater bicarbonate during high-temperature hydrothermal circulation. Here we present data from a suite of samples collected over the past 15 years from high-temperature hydrothermal vents at 9N, Endeavour, Lau Basin, and the MAR that have endmember CO2 concentrations less than 10 mmol/kg. Using stable and radiocarbon isotope measurements these samples provide a unique opportunity to examine the balance between 'original' seawater bicarbonate and CO2 added from magmatic sources. Multiple lines of evidence from multiple hydrothermal settings consistently points to the removal of ~80% of the 'original' 2.3 mmol/kg seawater bicarbonate. Assuming that this removal occurs in the low-temperature, 'recharge' limb of hydrothermal circulation, this removal process is widely occurring and has important contributions to the global carbon cycle over geologic time. 1.

Student motivation, engagement, and completion are important topics in the study of Massive Open Online Courses (MOOCs). Many science-focused Massive Open Online Courses (MOOCs) appeal to lifelong learners interested in general education as opposed to career development, yet little motivation-related research has been conducted with students in these courses. We present the results of a study that examined the motivations of MOOC students in our class, Astronomy: Exploring Time and Space. We examined trends in motivation and participation for these non-career-focused students. Although we have been able to show that the students in our class are similar, demographically, to other MOOC classes, our research has shown that they have very different motivations from undergraduate students, or MOOC students who are intere “average” MOOC user. Astronomy: Exploring Time and Space students are much more likely to be astronomy hobbyists, or taking the class to satisfy their curiosity and not attempting to change careers or achieve a credential. We were also able to correlate the results of the motivation survey instruments with student engagement with course materials and rates of course completion. We examined the motivations of students using both the validated Science Motivation Questionnaire II by Glynn et. al (2011) and a motivation instrument developed by John Falk for learners in free-choice settings. These allowed us to compare our results with other researchers who have used these instrument in other educational settings, including MOOCs. Students who reported high levels of self-determination were the most likely to complete the course, while high social motivation was a poor predictor of completion and performance.

Teaching a Relational Approach to Climate Change: Working with People and Conflict

Science.gov (United States)

Kearns, F.

2015-12-01

In 2010, science and technology studies expert Sheila Jasanoff concluded an article in Science by observing that the scientific community "…has demonstrated that it can learn and change in its methods of representing science to scientists. That ingenuity should now be directed toward building relationships of trust and respect with the global citizens whose future climate science has undertaken to predict and reshape." This kind of statement indicates a large shift in the focus on climate-related work, in a sense concluding that the scientific conclusions are well-established, but there is a human-to-human, relationship-based element of the work that needs attention. At the same time, there is increasing emphasis on transitioning to more participatory models of research, practice, and engagement in climate work, the human relationships that underlie these approaches are rarely explicitly addressed. For example, conflict, a key relational process, is often an inevitable element of engagement in societal processes. Although conflict can lead toward more successful long-term solutions if addressed constructively, dealing with it can be highly uncomfortable on an individual level and is often avoided. Acknowledging the often pivotal role conflict plays in eventual solutions bolsters the notion of complementing current training with a focus on relationship building. Professional development to increase relational capacity is being adopted in fields such as law and medicine; these same approaches are also increasingly relevant for climate practitioners where strong emotions such as grief and anxiety are often present for both practitioners and those they interact with. A framework for teaching and learning to effectively interact in this rich, relational world will be presented.

Full Text Available Surveys for freshwater sponges were performed at several water bodies at sandy environments along a north-south direction of particularly the Brazilian coastal line. The results allowed for the distinction of four different species-specific environments along this coastal border. The main fact considered was the dominant or the sole recurrent occurrence of a single sponge species at one particular habitat. The first one is that of the lagoonal mesohaline habitats at the tropical and subtropical realms, indicated by Spongilla alba Carter, 1849. The second one refers to shallow ponds among dunes at the tropical area indicated by Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974. The third one is that of also shallow ponds close to the dune belt at the temperate region indicated by Racekiela sheilae (Volkmer-Ribeiro, De Rosa-Barbosa & Tavares, 1988. The fourth one is that of organically enriched environments, at the marginal areas of lagoons and mouth of small rivers, evolving towards freshwater muddy ponds and coastal swamps, not far from the ocean border: Ephydatia facunda Weltner, 1895 is the species to occupy this habitat with almost exclusiveness. The above species are thus proposed as indicators of such habitats and have their descriptions improved and that of their environments summarized. A taxonomic key based on the spicules of the four species is proposed. The results presented aim to contribute to the identification of spicules of these sponges in sediment columns recovered at the Brazilian and South American coastal area. Determination of paleo ocean borders are a present issue of upmost importance in what respects projections of timing and fluctuations of ascending/regressing sea levels.Levantamentos para detecção de esponjas dulcícolas foram conduzidos em diversos corpos d'água da faixa arenosa costeira, de norte a sul, particularmente no Brasil.

The Challenges and Achievements in 50 Years of Human Spaceflight

On April 12, 1961 the era of human spaceflight began with the orbital flight of Cosmonaut Yuri Gagarin. On May 5, 1961 The United States responded with the launch of Alan Shepard aboard Freedom 7 on the first flight of Project Mercury. The focus of the first 20 years of human spaceflight was developing the fundamental operational capabilities and technologies required for a human mission to the Moon. The Mercury and Gemini Projects demonstrated launch and entry guidance, on-orbit navigation, rendezvous, extravehicular activity, and flight durations equivalent to a round-trip to the Moon. Heroes of this epoch included flight directors Chris Kraft, Gene Kranz, and Glynn Lunney along with astronauts like John Young, Jim Lovell, Tom Stafford, and Neil Armstrong. The "Race to the Moon” was eventually won by the United States with the landing of Apollo 11 on July 20, 1969. The Apollo program was truncated at 11 missions and a new system, the Space Shuttle, was developed which became the focus of the subsequent 30 years. Although never able to meet the flight rate or cost promises made in the 1970s, the Shuttle nevertheless left a remarkable legacy of accomplishment. The Shuttle made possible the launch and servicing of the Hubble Space Telescope and diverse activities such as life science research and classified national security missions. The Shuttle launched more than half the mass ever put into orbit and its heavy-lift capability and large payload bay enabled the on-orbit construction of the International Space Station. The Shuttle also made possible spaceflight careers for scientists who were not military test pilots - people like me. In this talk I will review the early years of spaceflight and share my experiences, including two missions with HST, from the perspective of a five-time flown astronaut and a senior flight operations manager.

Recent advances in photoinduced donor/acceptor copolymerization

Photoinitiated free radical polymerization of donor (D)/acceptor (A) type monomers has gained considerable interest due to the possibility to efficiently photopolymerize non-acrylate based systems. Furthermore, this photoinduced alternating copolymerization can be accomplished without the presence of a conventional free radical generating photoinitiator. In the past, we have shown that the structural influences in the direct photolysis of N-Alkyl and N-Arylmaleimides as well as their corresponding ground state charge transfer complexes (CTC) with suitable donors have carefully been investigated. For certain combinations of A and D type monomers, a direct photolysis of the ground state complex or the excitation of the acceptor, followed by the formation of an exciplex, has been shown to initiate the copolymerization. Herein, we show that the main route of initiation is based on inter or intra molecular H-abstraction from an excited state maleimide, whereby no exciplex formation takes place. H-abstraction will predominantly take place in systems where easily abstractable hydrogens are present. Our laser flash photolysis investigation, ESR (A. Hiroshi, I. Takasi, T. Nosi, Macromol. Chem. 190 (1989) 2821) and phosphorescence emissions (K.S. Chen, T. Foster, J.K.S. Wan, J. Phys. Chem. 84 (1980) 2473; C.J. Seliskar, S.P. McGlynn, J. Chem. Phys. 55 (1971) 4337) studies show that triplet excited states of N-alkyl substituted maleimides (RMI), which are well known strong precursors for direct H-abstractions from aliphatic ethers and secondary alcohols, are formed upon excitation. Rates of copolymerization and degrees of conversion for copolymerization of maleimide/vinyl ether pairs in air and nitrogen have been measured as a function of hydrogen abstractability of the excited triplet state MI as well as the influence of concentration and hydrogen donating effect of the hydrogen donor

This collection of essays stems from the Workshop on Cosmology and Time held at the Pennsylvania State University on April 16-17, 2013, with support from the Department of Philosophy, the Schreyer Honors College, and the Center for Fundamental Theory/Institute for Gravitation and the Cosmos. My thanks to Shannon Sullivan and Susan Welch, Arun Upneja and Christian Brady, and Abhay Ashtekar, Murat Gunaydin and Randi Neshteruk. I'd also like to acknowledge helpful counsel from Gordon Fleming (Professor of Physics Emeritus, Penn State), who has been generous with his time and expertise, and John Norton (Director, Center for History and Philosophy of Science, University of Pittsburgh), who not only contributed to the workshop but also introduced me to the work of two of his graduate students. The original intention of the workshop was to pair younger scholars with older, more established scholars; during the workshop, we listened to exchanges between Bryan Roberts and Abhay Ashtekar, William Nelson and Sarah Shandera, Thomas Pashby and Gordon Fleming, David Sloan and Kurt Gibble, Elie During and myself, and Alexis de Saint-Ours and John Norton. Though some of these exchanges did not persist through the creation of this collection of essays, those that did were further developed in useful ways. I also wanted to bring philosophers and scientists together, as well as colleagues from Europe and North America. The latter intention was strengthened by the later addition of responses or essays by Jeremy Butterfield, Julian Barbour, Klaus Mainzer, and Lee Smolin, to complement the 'overview' essays by Abhay Ashtekar and John Norton that begin and end the second part. Though the thoughtful and stimulating essays and responses by William Nelson, Sarah Shandera, Kurt Gibble, Elie During and Klaus Mainzer did not survive the process of assembling this special issue, because they were too technical or did not fit in structurally or could not be revised in time, their contributions

However the influence of dietary supplemented n-3-LC-PUFAs on inflammation-related cell death and proliferation after middle cerebral artery occlusion (MCAo-induced stroke is unknown. We have previously demonstrated that anxiety-like and hyperactive locomotor behaviors are reduced in n-3-LC-PUFA-fed MCAo animals. Thus in the present study, male hooded Wistar rats were exposed to MCAo or sham surgeries and examined behaviorally 6 weeks later, prior to euthanasia and examination of lesion size, cell death and proliferation in the dentate gyrus, cornu ammonis region of the hippocampus of the ipsilesional hemispheres, and the thalamus of the ipsilesional and contralesional hemispheres. Markers of cell genesis and cell degeneration in the hippocampus or thalamus of the ipsilesional hemisphere did not differ between surgery and diet groups 6 weeks post MCAo. Dietary supplementation with n-3-LC-PUFA decreased cell degeneration and increased cell proliferation in the thalamic region of the contralesional hemisphere. MCAo–associated cell degeneration in the hippocampus and thalamus positively correlated with anxiety-like and hyperactive locomotor behaviors previously reported in these animals. These results suggest that anti-inflammatory n-3-LC-PUFA supplementation appears to have cellular protective effects after MCAo in the rat, which may affect behavioral outcomes.

MBIs have aimed to facilitate physical and emotional adjustment to life with cancer through the cultivation and practice of mindfulness (ie, purposeful, nonjudgmental, moment-to-moment awareness. This descriptive review highlights three categories of outcomes that have been evaluated in MBI research with cancer patients – namely, symptom reduction, positive psychological growth, and biological outcomes. We also examine the clinical relevance of each targeted outcome, while describing recently published original studies to highlight novel applications of MBIs tailored to individuals with cancer. Accumulating evidence suggests that participation in a MBI contributes to reductions in psychological distress, sleep disturbance, and fatigue, and promotes personal growth in areas such as quality of life and spirituality. MBIs may also influence markers of immune function, hypothalamic–pituitary–adrenal axis regulation, and autonomic nervous system activity, though it remains unclear whether these biological changes translate to clinically important health benefits. We conclude by discussing methodological limitations of the extant literature, and implications of matching MBIs to the needs and preferences of cancer patients. Overall, the growing popularity of MBIs in cancer care must be balanced against scientific evidence for their impact on specific clinical outcomes. Keywords: mindfulness-based intervention

Affected patients have absent or negligible ventilatory sensitivity to hypercapnia and hypoxemia, and they do not exhibit signs of respiratory distress when challenged with hypercarbia or hypoxia. The diagnosis of CCHS must be confirmed with PHOX2B gene mutation. Generally, the PHOX2B mutation genotype can aid in anticipating the severity of the phenotype. They require ventilatory support for life. Home assisted ventilation options include positive pressure ventilation via tracheostomy, noninvasive positive pressure ventilation, and diaphragm pacing via phrenic nerve stimulation, but each strategy has its associated limitations and challenges. Since all the clinical manifestations of CCHS may not manifest at birth, periodic monitoring and early intervention are necessary to prevent complications and improve outcome. Life-threatening arrhythmias can manifest at different ages and a normal cardiac monitoring study does not exclude future occurrences leading to the dilemma of timing and frequency of cardiac rhythm monitoring and treatment. Given the rare incidence of CCHS, most health care professionals are not experienced with managing CCHS patients, particularly those with diaphragm pacers. With early diagnosis and advances in home mechanical ventilation and monitoring strategies, many CCHS children are surviving into adulthood presenting new challenges in their care.

Micro acoustic resonant chambers for heating/agitating/mixing (MARCHAM)

A variety of applications require the mixing and/or heating of a slurry made from a powder/fluid mixture. One of these applications, Sub Critical Water Extraction (SCWE), is a process where water and an environmental powder sample (sieved soil, drill cuttings, etc.) are heated in a sealed chamber to temperatures greater than 200 degrees Celsius by allowing the pressure to increase, but without reaching the critical point of water. At these temperatures, the ability of water to extract organics from solid particulate increases drastically. This paper describes the modeling and experimentation on the use of an acoustic resonant chamber which is part of an amino acid detection instrument called Astrobionibbler [Noell et al. 2014, 2015]. In this instrument we use acoustics to excite a fluid- solid fines mixture in different frequency/amplitude regimes to accomplish a variety of sample processing tasks. Driving the acoustic resonant chamber at lower frequencies can create circulation patterns in the fluid and mixes the liquid and fines, while driving the chamber at higher frequencies one can agitate the fluid and powder and create a suspension. If one then drives the chamber at high amplitude at resonance heating of the slurry occurs. In the mixing and agitating cell the particle levitation force depends on the relative densities and compressibility's of the particulate and fluid and on the kinetic and potential energy densities associated with the velocity and pressure fields [Glynne-Jones, Boltryk and Hill 2012] in the cell. When heating, the piezoelectric transducer and chamber is driven at high power in resonance where the solid/fines region is modelled as an acoustic transmission line with a large loss component. In this regime, heat is pumped into the solution/fines mixture and rapidly heats the sample. We have modeled the piezoelectric transducer/chamber/ sample using Mason's equivalent circuit. In order to assess the validity of the model we have built and

Despite this, nonadherence to medication is common in RA. We explored the determinants of high and low adherence to disease-modifying antirheumatic drugs (DMARDs in patients with RA and provide suggestions on approaches to improving adherence to DMARDs.Methods: Patients with RA were identified from those who had previously participated in a questionnaire measuring levels of medication adherence. Twenty patients participated (ten high and ten low adherers, as determined by responses to the Medication Adherence Report Scale. In-depth individual semistructured interviews were undertaken until data saturation was reached. Interviews were transcribed and analyzed using a constant comparative method.Results: Four main themes related to adherence were identified: 1 symptom severity; 2 illness perception; 3 perceived benefits and risks of DMARDs; and 4 the quality and quantity of information about RA and DMARDs. In addition, patients’ suggestions about strategies to optimize adherence to DMARDs were captured and they fell within the following themes: 1 musculoskeletal ultrasound to explain the disease process and to provide objective feedback about the extent to which their disease activity is being effectively controlled; 2 better explanations of the consequences of poorly controlled RA; and 3 a good relationship with the health professional.Conclusion: Patients’ beliefs about medicines, perceptions about RA, and level of satisfaction with information about DMARDs influenced their adherence to DMARDs.

Is Middle-Upper Arm Circumference "normally" distributed? Secondary data analysis of 852 nutrition surveys.

Frison, Severine; Checchi, Francesco; Kerac, Marko; Nicholas, Jennifer

2016-01-01

Wasting is a major public health issue throughout the developing world. Out of the 6.9 million estimated deaths among children under five annually, over 800,000 deaths (11.6 %) are attributed to wasting. Wasting is quantified as low Weight-For-Height (WFH) and/or low Mid-Upper Arm Circumference (MUAC) (since 2005). Many statistical procedures are based on the assumption that the data used are normally distributed. Analyses have been conducted on the distribution of WFH but there are no equivalent studies on the distribution of MUAC. This secondary data analysis assesses the normality of the MUAC distributions of 852 nutrition cross-sectional survey datasets of children from 6 to 59 months old and examines different approaches to normalise "non-normal" distributions. The distribution of MUAC showed no departure from a normal distribution in 319 (37.7 %) distributions using the Shapiro-Wilk test. Out of the 533 surveys showing departure from a normal distribution, 183 (34.3 %) were skewed (D'Agostino test) and 196 (36.8 %) had a kurtosis different to the one observed in the normal distribution (Anscombe-Glynn test). Testing for normality can be sensitive to data quality, design effect and sample size. Out of the 533 surveys showing departure from a normal distribution, 294 (55.2 %) showed high digit preference, 164 (30.8 %) had a large design effect, and 204 (38.3 %) a large sample size. Spline and LOESS smoothing techniques were explored and both techniques work well. After Spline smoothing, 56.7 % of the MUAC distributions showing departure from normality were "normalised" and 59.7 % after LOESS. Box-Cox power transformation had similar results on distributions showing departure from normality with 57 % of distributions approximating "normal" after transformation. Applying Box-Cox transformation after Spline or Loess smoothing techniques increased that proportion to 82.4 and 82.7 % respectively. This suggests that statistical approaches relying on the

Ted Irving and the Precambrian continental drift of (within?) the Canadian Shield

Hoffman, P. F.

2014-12-01

Ted Irving was no stranger to the Precambrian when he began paleomagnetic studies in the Canadian Shield (CS) that would dominate his research in the early and mid-1970's. Twenty years before, his graduate work on billion-year-old strata in Scotland established paleomagnetic methodologies applicable to sedimentary rocks generally. In 1958, he and Ronald Green presented an 'Upper Proterozoic' APW path from Australia as evidence for pre-Carboniferous drift relative to Europe and North America (the poles actually range in age from 1.2 to 2.7 Ga). His first published CS poles were obtained from the Franklin LIP of the Arctic platform and demonstrate igneous emplacement across the paleoequator. Characteristically, his 1971 poles are statistically indistinguishable from the most recent grand mean paleopole of 2009. His main focus, however, was on the question of Precambrian continental drift. He compared APW paths with respect to Laurentia with those obtained from other Precambrian shields, and he compared APW paths from different tectonic provinces within the CS. He was consistently antagonistic to the concept of a single long-lived Proterozoic supercontinent, but he was on less certain ground regarding motions within the CS due to inadequate geochronology. With Ron Emslie, he boldly proposed rapid convergence between parts of the Grenville Province and Interior Laurentia (IL) ~1.0 Ga. This was controversial given the uncertain ages of multiple magnetic components in high-grade metamorphic rocks. With John McGlynn and John Park, he developed a Paleoproterozoic APW path for the Slave Province from mafic dikes and red clastics, encompassing the time of consolidation of IL during 2.0-1.8 Ga orogenesis. Before 1980, he constructed Paleoproterozoic APW paths for IL as a whole, finding little evidence for significant internal displacement. He recognized that the Laurentian APW path describes a series of straight tracks linked by hairpins, the latter corresponding in age to

Untangling the Impacts of Climate Variability on Atmospheric Rivers and Western U.S. Precipitation Using PERSIANN-CONNECT

Atmospheric Rivers (ARs), the large plumes of moisture transported from the tropics, impact many aspects of society in the Western U.S. When ARs make landfall, they are often associated with torrential rains, swollen rivers, flash flooding, and mudslides. We demonstrate that by viewing precipitation events associated with ARs as "objects", calculating their physical characteristics (mean intensity (mm/hr), speed (km/hr), etc.), assigning environmental characteristics (e.g. phase of the El Nino Southern Oscillation) for each system, and then performing empirical analyses, we can reveal interactions between different climate phenomena. To perform this analysis, we use a unique object oriented data set based on the gridded, satellite precipitation data from the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN) algorithm known as PERSIANN-CONNECT, for the period 3/2000 to 12/2010. The data is segmented into 4D objects (longitude, latitude, time and intensity). Each of the segmented precipitation systems is described by over 72 characteristics. A search of the PERSIANN-CONNECT database for all Western U.S. large-scale precipitation systems returns 626 systems. Out of the 626 large-scale precipitation systems, 200 occurred at the same time as documented Western U.S. land falling ARs (a list of ARs provided by Dr. Martin Ralph). Here we report the physical and environmental characteristics for these 200 storms including a comparison to the 426 non-AR storms. We also report results of an analysis of the δ18O measurements collected from Giant Forest, Sequoia National Park in the Southwestern Sierra Nevada Mountains (McCabe-Glynn et al., in prep.) for the 200 AR precipitation systems. For an overall assessment of the impacts of climate variability on all 626 precipitation systems, we focus on ENSO, and show that during El Nino/La Nina, as compared with Neutral phases of ENSO, the systems are larger (9505, 9097, vs. 6075km

Full Text Available Holly Taggart,1 Sheila Greatrex-White,2 1Mental Health Commission, CentreForum, Westminster, UK; 2School of Health Sciences, Queen's Medical Centre, University of Nottingham, Nottingham, UK Aim: To identify relevant and pertinent themes and interventions within the literature relating to childhood traumatic grief, in order to provide a sound background of evidence for further research and service development. Background: Childhood traumatic grief is caused when a significant person in a child's life dies under circumstances that they perceive to be traumatic. This can leave a child unable to return to the same level of physical and emotional functioning that he or she had prior to the death occurring. In Sub-Saharan Africa, there is an increased risk for childhood traumatic grief due to a high prevalence of orphanhood, environmental stressors, stigma, and abuse. This can have detrimental effects upon mental health. Methods: The review followed the York methodology: identifying the purpose and agreeing on the strategy beforehand; identifying relevant sources/studies; selecting the studies; charting the data; and collating, summarizing, and reporting results. Results and discussion: Interventions identified to prevent and/or manage traumatic grief included narrative exposure therapy, psychotherapy, mentoring, peer-group support, psychosocial support, a grief and loss therapy session, and memory boxes. Mental health remains neglected within service and policy development as well as in global health spending. The average amount expended on mental health services per person per year in low-income countries is less than $0.25. Only 36% of people in low income countries are covered by a mental health policy, compared with 92% in high income countries. Limitations: The sixth stage of the York methodology was omitted. Only papers written in English were included in the review. Conclusion: Childhood traumatic grief in young people is an important issue

They are selectively replication-competent viruses that propagate only in actively dividing tumor cells but not in normal cells and, as a result, destroy the tumor cells by consequence of lytic infection. At least six different oncolytic herpes simplex viruses (oHSVs have undergone clinical trials worldwide to date, and they have demonstrated an excellent safety profile and intimations of efficacy. The first pivotal Phase III trial with an oHSV, talimogene laherparepvec (T-Vec [OncoVexGM-CSF], is almost complete, with extremely positive early results reported. Intuitively, therapeutically beneficial interactions between oHSV and chemotherapeutic and targeted therapeutic drugs would be limited as the virus requires actively dividing cells for maximum replication efficiency and most anticancer agents are cytotoxic or cytostatic. However, combinations of such agents display a range of responses, with antagonistic, additive, or, perhaps most surprisingly, synergistic enhancement of antitumor activity. When synergistic interactions in cancer cell killing are observed, chemotherapy dose reductions that achieve the same overall efficacy may be possible, resulting in a valuable reduction of adverse side effects. Therefore, the combination of an oHSV with “standard-of-care” drugs makes a logical and reasonable approach to improved therapy, and the addition of a targeted oncolytic therapy with “standard-of-care” drugs merits further investigation, both preclinically and in the clinic.

We hypothesized that improved air quality in North Carolina was associated with reduced rates of death from respiratory diseases in local populations. Materials and methods: We analyzed the trends of emphysema, asthma, and pneumonia mortality and changes of the levels of ozone, sulfur dioxide (SO2, nitrogen dioxide (NO2, carbon monoxide (CO, and particulate matters (PM2.5 and PM10 using monthly data measurements from air-monitoring stations in North Carolina in 1993–2010. The log-linear model was used to evaluate associations between air-pollutant levels and age-adjusted death rates (per 100,000 of population calculated for 5-year age-groups and for standard 2000 North Carolina population. The studied associations were adjusted by age group-specific smoking prevalence and seasonal fluctuations of disease-specific respiratory deaths. Results: Decline in emphysema deaths was associated with decreasing levels of SO2 and CO in the air, decline in asthma deaths–with lower SO2, CO, and PM10 levels, and decline in pneumonia deaths–with lower levels of SO2. Sensitivity analyses were performed to study potential effects of the change from International Classification of Diseases (ICD-9 to ICD-10 codes, the effects of air pollutants on mortality during summer and winter, the impact of approach when only

During a May 2009 cruise to W Mata volcano in the NE Lau Basin, we made the first observations of an active eruption on the deep-sea floor. The cruise was organized after volcanic activity was detected at two sites (W Mata volcano and NE Lau Spreading Center, NELSC) during a Nov. 2008 NOAA-PMEL expedition. At that time, both sites had elevated H2 concentrations and volcaniclastic shards in the hydrothermal plumes. Moored hydrophone data since Jan 2009 indicate that the activity at W Mata has been continuous between these expeditions. Results of our cruise and other work suggest that the NE Lau Basin hosts an unusually high level of magmatic activity, making it an ideal location to study the effects of magmatic processes on hydrothermal activity and associated ecosystems. W Mata was visited with 5 ROV Jason 2 dives and 2 dives with the MBARI autonomous mapping vehicle in May 2009. It was actively erupting at the 1200 m deep summit during each, so a hydrophone was deployed locally to collect acoustic data. Ship and shore-based analysis of HD video, molten lava, rocks, sediments, hot spring waters, and micro- and macro biological specimens collected by Jason 2 have provided a wealth of data. The eruption itself was characterized by extrusion of red, molten lava, extensive degassing, formation of large magma bubbles, explosive pyroclast ejection, and the active extrusion of pillow lavas. The erupting magmas are boninite, a relatively rare magma type found only at convergent margins. The hydrothermal fluids are generally acidic and all diffuse fluids collected were microbially active, even those at pH 20 yrs the PMEL-Vents and NSF RIDGE programs have sought to observe

, underpin this approach (Johnes & Butterfield, 2002). Ten regions have been defined across the UK using GIS manipulation of spatial data describing hydrogeology, runoff, topographical slope and soil parent material. The export coefficient model operates within this regional modelling framework, providing mapped, tabulated and statistical outputs at scales from 1km2 grid scale to river catchment, WFD river basin district, major coastal drainage units to the North Sea, North Atlantic and English Channel, to the international reporting units defined under OSPAR, the International Convention for the protection of the marine environment of the North-East Atlantic. Here the geoclimatic modelling framework is presented together with modelled fluxes for N and P for each scale of reporting unit, together with scenario analysis applied at regional scale and mapped at national scale. The ways in which the results can be used to further explore the primary drivers for spatial variation and identify waterbodies at risk, especially in unmonitored and data-poor catchments are discussed, and the technical and computational support of a cloud-based infrastructure is evaluated as a mechanism to explore potential water quality impacts of future mitigation strategies applied at catchment to national scale.

Subthemes explain the evolution of the two-way conversation, and having, using, and supporting the two-way conversation with patients, primarily as this relates to achieving adherence and health outcomes. Emerging ethical concerns were related to the ambiguity of the ideal of empowered patients and the ways in which health professionals described enacting those ideals in practice, showing how the cultural shift toward truly mutually respectful and collaborative practice is in transition. HCPs aim to act in the best interests of their patients; the challenge is to benefit from emergent technologies that may enhance patient-HCP interactions and effective care, while abiding by regulations, dealing with the strictures of the technology itself, and managing changing demands on their time. ©Graham G Macdonald, Anne F Townsend, Paul Adam, Linda C Li, Sheila Kerr, Michael McDonald, Catherine L Backman.

Piling Foundation is one of the foundations which is used to penetrate its load through soil layer. The power carried by the piling is obtained from the end bearing capacity, that is, the compressive end piling and friction bearing capacity obtained from friction bearing and adhesive capacity between the piling and the soil around it. The investigation on the Standard Penetration Test is aimed to get the description of soil layer, based on the type and color of soil through visual observation, and soil characteristics. SPT data can be used to calculate bearing capacity. Besides investigating the SPT, this study is also been equipped by taking the samples in laboratory and loading test on the piling and Ducth Cone Penetrometer (DCP) data to confirm its bearing capacity. This study analyzed bearing capacity and settlement in the square pile of 40X40 cm in diameter in a single pile or grouped, using an empirical method, AllPile program, Plaxis program, and comparing the result with interpreting its loading test in the foundation of Rusunawa project, Jatinegara, Jakarta. The analysis was been done by using the data on soil investigation and laboratory by comparing them with Mohr-Coulomb soil model. Ultimate bearing capacity from the SPT data in the piling of 15.4 meters was 189.81 tons and the parameter of soil shear strength was 198.67 tons. The sander point, based on Aoki and De Alencar bearing capacity was 276.241 tons and based on Mayerhoff it was 305.49 tons. Based on the loading test of bearing capacity, unlimited bearing capacity for the three methods was Davisson (260 tons), Mazurkiewich (270 tons), and Chin (250 tons). The efficiency of grouped piles according to Converse-Library Equation method = 0.73, according to Los Angeles Group Action Equation method = 0.59, and according to Sheila-Keeny method = 0.94. Bearing capacity based on piling strength was 221.76 tons, bearing capacity based on calendaring data was 201.71 tons, and lateral bearing capacity of a

according to the NASA Task Load Index (NASA-TLX). From our observation of older adults' interactions with smartphone interfaces, there were some recurring themes. Clear and relevant feedback as the user attempts to complete a task is critical. Feedback should include pop-ups, sound tones, color or texture changes, or icon changes to indicate that a function has been completed successfully, such as for the connection sequence. For text feedback, clear and unambiguous language should be used so as not to create anxiety, particularly when it comes to saving data. Warning tones or symbols, such as caution symbols or shrill tones, should only be used if absolutely necessary. Our HCD methodology, designed and implemented based on the principles of the International Standard Organizaton (ISO) 9241-210 standard, produced a functional app interface within a short production cycle, which is now suitable for use by older adults in long term clinical trials. ©Richard Harte, Leo R Quinlan, Liam Glynn, Alejandro Rodríguez-Molinero, Paul MA Baker, Thomas Scharf, Gearóid ÓLaighin.

Evidence-based practice is not about the survival of school librarians, it’s about the survival of our students” (40. In this issue we feature school libraries and their connection to evidence based practice. Former Editor-in-Chief, Lindsay Glynn, began putting the wheels in motion for this feature almost a year ago. She invited Carol Gordon and Ross Todd to act as guest editors of the section, drawing upon their contacts and previous work in this field. The result is an issue with five feature articles exploring different aspects of the connection between school libraries and evidence based practice, from the theoretical to the practical. In addition, there is a thought-provoking Commentary by David Loertscher, asking whether we need the evolutionary model of evidence based practice, or something more revolutionary!In addition to the Feature section, we have a well-rounded issue with articles on the topics of library human resources, and the development of a scholars’ portal. As well, there are a record 10 evidence summaries and our educational EBL101 column. I hope there is something for everyone in this issue of EBLIP – enjoy, and see you soon in Stockholm!

and progression opportunities for science specialists, whilst ensuring that the general public are scientifically literate. I think physics education has a serious contribution to make to all sections of society:The specialist, preparing for and progressing in a scientific/technological career. The skilled worker, analysing, understanding and innovating in any occupation. The citizen coping with increasing complexity in society. The individual trying to understanding the world into which they were born. To continue improving our educational systems and to assist each of these groups demands a grand alliance of people involved in physics education. Reflecting first on the wider context can help us choose appropriate points at which to intervene. Otherwise, educational improvement may be hampered, with valuable effort expended on positive reform actions rendered useless by constraints elsewhere in the system. How has the subject and its place in the curriculum evolved? What can be learned from previous curriculum innovations? What do public perceptions of physics tell us? The aim of the fifth Shaping the Future booklet is to encourage debate about where reform efforts should best be directed. Contributors will include Steve Adams, Michael Barnett, Sheila Carlton, John Berkeley, Martin Hollins, Marilyn Holyoake, Andrew Hunt, Roland Jackson, Jon Ogborn, Russell Stannard and Charles Thomas. A Discussion Meeting based on Physics in a wider context, at the ASE Annual Meeting, Leeds, promises to be lively. I hope you will come and express your views!

Scoville, Nick

2009-01-01

Philip Solomon, one of the pioneers and leading researchers in molecular astrophysics, died on 30 April 2008 at his apartment on the upper west side of Manhattan after a battle with cancer. His pioneering research included both theoretical and very extensive observational studies of stellar atmospheres, interstellar molecules, high redshift galaxies, and the Earth's stratosphere. Phil was Distinguished Professor at The State University of New York [SUNY], Stony Brook, where he had been since 1974. Phil was born on 29 March 1939 in Manhattan, New York City, to Nat and Betty Solomon. Nat Solomon was a labor organizer and a printer. Phil attended the University of Wisconsin, where he received his BS in 1959 and where he met his future wife Sheila who was studying art. His Ph.D., "On the Role of Light Molecules in Astrophysics," was also from the University of Wisconsin under the guidance of Art Code and Bob Bless. After postdoctoral positions at Princeton and lectureships at Columbia and the University of California, San Diego, Phil spent two years as a Professor at the University of Minnesota. After two years at the Institute for Advanced Study in Princeton, he came to SUNY, Stony Brook, as Professor of Astronomy in the Department of Earth and Space Sciences. In 1988 Phil was selected as a Humboldt Senior Distinguished Scientist, and, in 1999, he was honored with the rank of Distinguished Professor at SUNY. Phil took sabbatical and other leaves at Churchill College and the Institute of Astronomy, Cambridge; the Institute for Advanced Study; l'Ecole Normale Superieure, Paris; Institut d'Astrophysique, Paris; and the Institut de Radioastronomie Millimetrique [IRAM], France. Phil published more than 160 papers and supervised seven Ph.D. students. He served on numerous review, visiting, and advisory panels. Phil's first theoretical research focused on opacity and abundance of light molecules such as H2, CO, and CN in stellar atmospheres, but then shifted quickly to the

Learning Atomic-Molecular Theory in Secondary School: The Role of Meta-Conceptual Awareness and Modelling Skills

Science.gov (United States)

Chan, Chi Keung

The aim of this study was to examine the contribution of students' meta-conceptual awareness and modelling skills to their conceptual change when learning atomic-molecular theory. Instructional materials used in the intervention covered three sub-topics: atomic structure, chemical bonding, and structures and properties. Glynn's (1991) Teaching with Analogy model and Chambliss's (2002) guidelines for constructing scientific texts were used as the frameworks for designing and implementing instructional materials for the intervention. Forty-five Secondary 4 chemistry students from two classes at a secondary school in Hong Kong participated in the study. The two classes were taught by the same teacher. The study consisted of two phases. During Phase I, which lasted for 6 weeks, Class A (n = 13) used the above-mentioned instructional materials to learn the three sub-topics, whereas Class B (n = 32) learned the same sub-topics using traditional textbook materials. To further examine the effects of the intervention, a 2-week switching-replication treatment was implemented in Phase II. Class A used traditional textbook materials for revision whereas Class B used the tailor-made instructional materials. A mixed-methods design was used to assess the effectiveness of the intervention. Based on the student misconceptions documented in the literature, a written test of the three sub-topics was developed. The test comprised 33 two-tier multiple-choice items. The test was administered three times: before Phase I (T1), just after Phase I and before Phase II (T2), and 2 weeks after Phase II (T3). Qualitative data were gathered from semi-structured interviews with five students. Three students from Class A and two students from Class B were interviewed individually after Phase I and Phase II, respectively, to assess students' understanding of the essential theoretical concepts and to assess students' modelling skills. The results of paired-samples t-test showed that there was a

Em relação ao recorte temático, deve ser ressaltada a atualização bibliográfica trazida pelas mais diferentes abordagens que deram ênfase ao cinema e ao seu contexto histórico. Assim, o texto de abertura do dossiê traz Arthur Autran, que analisa as relações entre as cinematografias da Argentina e do Brasil nas décadas de 1930 e 1940, tendo como eixo central a visita de Adhemar Gonzaga a Buenos Aires em 1934 e os contatos ali estabelecidos. Já Rafael de Luna Freire examina a conversão do circuito cinematográfico exibidor brasileiro para a projeção de filmes sonoros, atentando para as particularidades regionais e as dimensões tecnológicas e econômicas entre os anos 1929 e 1935. Ana Maria Veiga, por sua vez, se debruça sobre uma cineasta e filme pouco estudados, a saber, Tereza Trautman e o seu primeiro longa-metragem, Os homens que eu tive (1972, filme que após sua estreia foi censurado por vários anos.

13C values.In contrast to the single-sample-based models, the extended Gonfiantini & Zuppi model (Gonfiantini and Zuppi, 2003; Han et al., 2014) is a statistical approach. This approach can be used to estimate 14C ages when a curved relationship between the 14C and 13C values of the DIC data is observed. In addition to estimation of groundwater ages, the relationship between 14C and δ13C data can be used to interpret hydrogeological characteristics of the aquifer, e.g. estimating apparent rates of geochemical reactions and revealing the complexity of the geochemical environment, and identify samples that are not affected by the same set of reactions/processes as the rest of the dataset. The investigated water samples may have a wide range of ages, and for waters with very low values of 14C, the model based on statistics may give more reliable age estimates than those obtained from single-sample-based models. In the extended Gonfiantini & Zuppi model, a representative system-wide value of the initial 14C content is derived from the 14C and δ13C data of DIC and can differ from that used in single-sample-based models. Therefore, the extended Gonfiantini & Zuppi model usually avoids the effect of modern water components which might retain ‘bomb’ pulse signatures.The geochemical mass-balance approach constructs an adjustment model that accounts for all the geochemical reactions known to occur along an aquifer flow path (Plummer et al., 1983; Wigley et al., 1978; Plummer et al., 1994; Plummer and Glynn, 2013), and includes, in addition to DIC, dissolved organic carbon (DOC) and methane (CH4). If sufficient chemical, mineralogical and isotopic data are available, the geochemical mass-balance method can yield the most accurate estimates of the adjusted radiocarbon age. The main limitation of this approach is that complete information is necessary on chemical, mineralogical and isotopic data and these data are often limited.Failure to recognize the limitations and

at high risk for alcohol abuse attending MAP, defined as a structured programme that provided clients with controlled amounts of alcohol on a daily schedule, comparing no treatment, moderate drinking, brief intervention or 12-step variants. All study citations were collated into a single database. Two review author independently screened titles and abstracts and selected references potentially relevant to the review. Differences between selection lists were resolved by discussion. Two review authors independently evaluated whether studies should be included or excluded according to the eligibility criteria. In the event of a disagreement, a third author was consulted. No studies were included in the review. This systematic review was intended to assess the effectiveness of a brief MAP on the reduction of incidence of harmful behaviour; however, no evidence was available to make this comparison; 22 articles were considered possibly relevant and all were excluded. Most articles were excluded because they failed to compare or consider managed alcohol as the experimental or control intervention, as well as one study (Baker 2010), which was also excluded because study participants were under 18 years of age. No study reviewed offered an intervention that was compared with managed alcohol or considered it as the intervention of interest, providing insufficient evidence to address the objectives of the review. Four studies (Aalto 2001; Baker 2010; Bertholet 2005; Tracy 2007) considered alcohol reduction as an outcome of interest, while four engaged interventions in a shelter setting or targeted vulnerable people (Baker 2010; Bradford 2005; Lapham 1993; McGlynn 1993); only one study (Kidd 2011) offered a qualitative assessment of a participant being admitted to MAP, but offered no analysis of the programme itself. These results accurately reflect the use of MAPs in current practice as existing programmes are ongoing only in a small number of sample pilot projects that target

you share my hope that in the not too distant future science may come to be used exclusively for the benefit of all mankind.'. On the occasion of the unveiling of a plaque by the 'National Committee for Science and Engineering Commemorative Plaques' in honour of J D Bernal in his hometown of Nenagh, Martin Bernal (JD's son) wrote 'Now, 35 years after his death, John Desmond Bernal has received this ultimate accolade'. It is to be hoped that this meeting and these proceedings will help further an awakening to Bernal's enduring bequest: 'his vision of science as inextricably tied to philosophy and to politics'—Helena Sheehan. Roy Johnston, an active 'bernalite' has been promoting the idea of a national Bernal Center or Institute in Ireland. Dare we hope for a more enlightened and scientifically informed social order? Acknowledgements I would like to acknowledge the help and support of my colleagues on the Munster Group of the IOPI, John Corr, Denise Gabuzda, Gabriel Gallagher, Niall Smith and particularly Leah Wallace who shared much of the responsibility for organising the meeting. Thanks are also due to Maria Hinfelaar, Director, Limerick Institute of Technology who gave the opening address and to Martin Bernal who closed the meeting with some personal reminiscences of times spent with his father. A big thank you to Sheila Gilheany and Alison Hackett, as always, for their support and encouragement and Peter van der Burgt for his help with the meeting website. The Munster Group of the Institute of Physics in Ireland would like to acknowledge with gratitude sponsorship of this event by Limerick Institute of Technology, University of Limerick (Research Office; J D Bernal Science and Society Centre; Physics Department), Institute of Physics History of Physics Group and the Institute of Chemistry of Ireland. Most memorable tours of areas of 'Bernal-interest' in Nenagh were organised for the speakers by Nancy Murphy of The Ormond Historical Society. Thanks also to North

frequent visitor. While the most celebrated example of his engineering work was his massive contribution to the Atlantic telegraph cable, and his maritime and other inventions were used throughout the world, he was especially pleased to contribute to two important technical accomplishments in the north of Ireland, the occulting Holywood lighthouse and the Giant's Causeway tramway. Kelvin's interest in Ireland came again to the fore in the Home Rule debate at the end of the nineteenth century; Kelvin was vehemently opposed to Home Rule and became a passionate member of the Liberal Unionist party, a crucial factor in his becoming a peer. Accounts of these aspects of Kelvin's involvement with Ireland are given in our first four papers. The fifth paper was particularly appropriate for the meeting. It describes how an important contribution of Kelvin on optimal packing has been improved in Ireland by the speaker, Denis Weaire, himself, and how the result has been seen by the whole world in Beijing. Finally there is a discussion of Kelvin's place in the story of Irish science. There have been many highly accomplished Irish scientists, and the meeting showed clearly that Kelvin certainly deserves to be included among the greatest. Acknowledgments The meeting was the second regional event of the Institute of Physics (IOP) in Ireland, the first being the meeting on John Desmond Bernal: Science and Society held in Limerick in June 2006 and published in the same series as this volume. The meeting also benefited from the support of many bodies and institutions. We would like to thank the committee of the IOP in Ireland for providing finance and also giving their full support. We would particularly mention Vincent Casey, the Chair, who also chaired the afternoon session, Emma Sokell, the Secretary, and Denise Gabuzda and Kevin McGuigan, past and present Treasurers. We would also thank Sheila Gilheany and Alison Hackett for general help and encouragement, including assisting the

Universiti Putra. Their paper reports the findings of a study on the teaching and learning and technology factors of online English language courses at UNITAR (University Tun Abdul Razak, a virtual university in Malaysia. Both quantitative and qualitative approaches were employed in eliciting data via a questionnaire survey and in-depth interviews. Specifically, the paper reports on learners’ perceptions towards the teaching and learning as well as technology factors during the online English course they were engaged in.The thirteenth article is from Anadolu University, the communication Faculty on “Teacher Immediacy Behaviors and Participation in Computer Mediated Communication” which is written by Mestan KUCUK.He mention ih his article that affective and interactive indicators were the least used immediacy behaviors while cohesive indicators were mostly used by teacher in this case. Also data show that teachers’ interactive immediacy behaviors and immediate feedback determine students’ participation in asynchronous computer-mediated communication environment.Two books are reviewed in this issue. The first one is about “Narrative Research on Learning comparative and international perspectives”, Edited by Sheila Trahar” The first section of the book considers different perspectives on narrative as methodology, including its value in particular cultural contexts. The second section provides readers with international and comparative perspectives on the practical application of narrative methodology in a wide range of arenas worldwide. This combination of methodological issues with practical examples provides opportunities to examine how narrative as a methodology is applied in a range of ‘real world’ situations.The second reviewed book is titled as ONLINE SCIENCE LEARNING: Best Practices and Technologies andwritten by Kevin F. Downing and Jennifer K. Holtz This book will also benefit audiences within the science education community of practice and others

autores recorrem a uma documentação variada e oferecem informações detalhadas de uma diversidade de aspectos dessa modalidade educativa: materialidade, currículos, metodologias de ensino, população estudantil.Bruno Bontempi Jr, na sequencia, volta-se à Escola Politécnica de São Paulo e aos engenheiros paulistas formados pela instituição. Memórias, identidades e representações sociais entorno à profissão e à instituição são examinadas a partir da análise dos discursos de engenheiros e formandos, proferidos em sessões solenes da instituição entre 1899 e 1910. O autor afirma que essas instituições de ensino superior constituíram espaços de formação e sociabilidades e, de certa forma, as cerimônias de colação de grau são emblemáticas a esse respeito, não apenas pela ritualística altamente simbólica, mas também como momentos de visibilidade e proliferação discursiva das identidades e representações sociais internamente cultivadas e que se almejava legitimar socialmente.Para fechar este número, História da Educação oferece a seus leitores um documento precioso e uma resenha de obra fundamental. O documento é generosamente partilhado por Eduardo Arriada, Elomar Antonio Callegaro Tambara e Sheila Duarte e intitula-se A sciencia do bom homem Ricardo, titulo que os pesquisadores acrescem o oportuno complemento: um texto de leitura escolar no Brasil Imperial. Recorrentemente, nos eventos e nos balanços da produção em História da educação, vimos nos ressentindo do número de estudos e documentação lacunar acerca do período imperial.Eis um contributo que se soma aos demais já publicados pela revista para conhecimento dos pesquisadores da área. A apresentação do documento é primorosa: os autores explicam não apenas o momento histórico no qual figuraram diversos movimentos de laicização, mas também argumentam a escolha do complemento ao título. Não podemos designar, no século 19, no contexto educacional brasileiro
