  3. Walk the Talk. Integrated Sustainability Initiative

    SciTech Connect

    Sagebiel, John

    The overall objective of this project was to demonstrate, through a series of real-world applications of existing technology, the benefits to the University of Nevada, Reno and the community, of various sustainability efforts. The project was very successful and has stimulated the Campus to take on more projects after seeing the successes of those initial ones funded through this project. The three areas of this work could broadly be described as energy efficiency, renewable energy and recycling. Under the first project, the campus did several projects replacing or changing heating and cooling systems, using state funding. The DOE funding initiallymore » funded the replacement of lights in one campus parking garage with LED lights. Subsequently, the campus facilities group recognized how effective this was and leveraged funds to do the other two garages. Similarly with the renewable energy project, once the first system was installed and working well, the campus committed funds to more than double that system. Lastly, the recycling efforts expanded the use and awareness on campus and led the campus to begin using a single-stream recycling program once it became available in this area, hopefully leading to more participation by the campus community. Thus, overall the project areas each did what they were intended to do, which was to demonstrate the usefulness of these sustainability programs and thus encourage the campus to do more. All this great work helps the campus’ goals overall, but without additional effort would not reach beyond the campus. This was the objective of the education and outreach effort. The combination of events, websites, and videos enabled us to reach many key decision makers and at the same time provide a long-term presence on the web that we can use to further educate people. The overall goals were met or exceeded and will continue to pay dividends into the future.« less

    The European Paediatric Formulation Initiative (EuPFI), founded in 2007, aims to promote and facilitate the preparation of better and safe medicines for children through linking research and information dissemination. It brings together the capabilities of the industry, academics, hospitals, and regulators within a common platform in order to scope the solid understanding of the major issues, which will underpin the progress towards the future of paediatric medicines we want.The EuPFI was formed in parallel to the adoption of regulations within the EU and USA and has served as a community that drives research and dissemination through publications and the organisation of annual conferences. The membership and reach of this group have grown since its inception in 2007 and continue to develop and evolve to meet the continuing needs and ambitions of research into and development of age appropriate medicines. Five diverse workstreams (age-appropriate medicines, Biopharmaceutics, Administration Devices, Excipients and Taste Assessment & Taste Masking (TATM)) direct specific workpackages on behalf of the EuPFI. Furthermore, EuPFI interacts with multiple diverse professional groups across the globe to ensure efficient working in the area of paediatric medicines. Strong commitment and active involvement of all EuPFI stakeholders have proved to be vital to effectively address knowledge gaps related to paediatric medicines, discuss potential areas for further research and identify issues that need more attention and analysis in the future.

    2015-09-08

    In this News & Reviews Discussion, the recently launched EuPA (European Proteomics Association) Biobank Initiative is introduced in the context of current and future challenges in biobanking. The purpose of the initiative is to provide a forumand knowledge platform for integrating the extensive experiences collected by the EuPA community, and link it to the European and international biobanking communities at large. The specific impact of providing a forum and easy access to this type of information to the EuPA community is the potential of improving the quality of future sample collections and biobanks, the quality of the research produced from these sample collections, as well as the output and productivity from existing biobanks. The underutilization of biobanks has recently been identified as an emerging issue of biobankingworldwide. Measures to improve our ability to locate and access appropriate sample collections for a wide range of research purposes may enhance both the scientific quality and biobank sustainability, thereby contributing to the important task of moving our research beyond basic findings and mere publications, into clinical practice. This manuscript is intended as a Discussion piece, and represents a recollection of the presentation under the “EuPA Initiative” session at HUPO/EuPA 2014 in Madrid. The launch of the EuPA (European Proteomics Association) Biobank Initiative in the context of current and future challenges in biobanking is discussed.

    2018-06-14

    A review of European Union (EU)-funded initiatives linked to 'Real World Evidence' (RWE) was performed to determine whether their outputs could be used for the generation of real-world data able to support the European Medicines Agency (EMA)'s regulatory decision-making on medicines. The initiatives were identified from publicly available websites. Their topics were categorised into five areas: 'Data source', 'Methodology', 'Governance model', 'Analytical model' and 'Infrastructure'. To assess their immediate relevance for medicines evaluation, their therapeutic areas were compared with the products recommended for EU approval in 2016 and those included in the EMA pharmaceutical business pipeline. Of 171 originally identified EU-funded initiatives, 65 were selected based on their primary and secondary objectives (35 'Data source' initiatives, 15 'Methodology', 10 'Governance model', 17 'Analytical model' and 25 'Infrastructure'). These 65 initiatives received over 734 million Euros of public funding. At the time of evaluation, the published outputs of the 40 completed initiatives did not always match their original objectives. Overall, public information was limited, data access was not explicit and their sustainability was unclear. The topics matched 8 of 14 therapeutic areas of the products recommended for approval in 2016 and 8 of 15 therapeutic areas in the 2017-2019 pharmaceutical business pipeline. Haematology, gastroenterology or cardiovascular systems were poorly represented. This landscape of EU-funded initiatives linked to RWE which started before 31 December 2016 highlighted that the immediate utilisation of their outputs to support regulatory decision-making is limited, often due to insufficient available information and to discrepancies between outputs and objectives. Furthermore, the restricted sustainability of the initiatives impacts on their downstream utility. Multiple projects focussing on the same therapeutic areas increase the likelihood of

  7. Structural dissection of an interaction between transcription initiation and termination factors implicated in promoter-terminator cross-talk.

    Functional cross-talk between the promoter and terminator of a gene has long been noted. Promoters and terminators are juxtaposed to form gene loops in several organisms, and gene looping is thought to be involved in transcriptional regulation. The general transcription factor IIB (TFIIB) and the C-terminal domain phosphatase Ssu72, essential factors of the transcription preinitiation complex and the mRNA processing and polyadenylation complex, respectively, are important for gene loop formation. TFIIB and Ssu72 interact both genetically and physically, but the molecular basis of this interaction is not known. Here we present a crystal structure of the core domain of TFIIB in two new conformations that differ in the relative distance and orientation of the two cyclin-like domains. The observed extraordinary conformational plasticity may underlie the binding of TFIIB to multiple transcription factors and promoter DNAs that occurs in distinct stages of transcription, including initiation, reinitiation, and gene looping. We mapped the binding interface of the TFIIB-Ssu72 complex using a series of systematic, structure-guided in vitro binding and site-specific photocross-linking assays. Our results indicate that Ssu72 competes with acidic activators for TFIIB binding and that Ssu72 disrupts an intramolecular TFIIB complex known to impede transcription initiation. We also show that the TFIIB-binding site on Ssu72 overlaps with the binding site of symplekin, a component of the mRNA processing and polyadenylation complex. We propose a hand-off model in which Ssu72 mediates a conformational transition in TFIIB, accounting for the role of Ssu72 in transcription reinitiation, gene looping, and promoter-terminator cross-talk. © 2018 by The American Society for Biochemistry and Molecular Biology, Inc.

  15. Deubiquitylation of histone H2A activates transcriptional initiation via trans-histone cross-talk with H3K4 di- and trimethylation

    2008-01-01

    Transcriptional initiation is a key step in the control of mRNA synthesis and is intimately related to chromatin structure and histone modification. Here, we show that the ubiquitylation of H2A (ubH2A) correlates with silent chromatin and regulates transcriptional initiation. The levels of ubH2A vary during hepatocyte regeneration, and based on microarray expression data from regenerating liver, we identified USP21, a ubiquitin-specific protease that catalyzes the hydrolysis of ubH2A. When chromatin is assembled in vitro, ubH2A, but not H2A, specifically represses the di- and trimethylation of H3K4. USP21 relieves this ubH2A-specific repression. In addition, in vitro transcription analysis revealed that ubH2A represses transcriptional initiation, but not transcriptional elongation, by inhibiting H3K4 methylation. Notably, ubH2A-mediated repression was not observed when H3 Lys 4 was changed to arginine. Furthermore, overexpression of USP21 in the liver up-regulates a gene that is normally down-regulated during hepatocyte regeneration. Our studies revealed a novel mode of trans-histone cross-talk, in which H2A ubiquitylation controls the di- and trimethylation of H3K4, resulting in regulation of transcriptional initiation.

    2001-11-01

    Sleep talking is very common in the general population. Its prevalence remains stable from childhood through adulthood. Sleep talking is often associated with other parasomnias: sleep walking, sleep terrors or REM sleep behavior disorders. It may arise from either REM or non REM sleep, when associated with REM sleep it is more comprehensible and often associated with clear sentences and recall of sleep mentation. Sleep talking is a benign entity and does not require any treatment; however an exceptional organic cause or psychopathology should be suspected if the onset is late (after 25 years); if the mental content is too violent or too emotional.

  17. Activation of plasmacytoid dendritic cells with TLR9 agonists initiates invariant NKT cell-mediated cross-talk with myeloid dendritic cells.

    2006-07-15

    CD1d-restricted invariant NK T (iNKT) cells and dendritic cells (DCs) have been shown to play crucial roles in various types of immune responses, including TLR9-dependent antiviral responses initiated by plasmacytoid DCs (pDCs). However, the mechanism by which this occurs is enigmatic because TLRs are absent in iNKT cells and human pDCs do not express CD1d. To explore this process, pDCs were activated with CpG oligodeoxyribonucleotides, which stimulated the secretion of several cytokines such as type I and TNF-alpha. These cytokines and other soluble factors potently induced the expression of activation markers on iNKT cells, selectively enhanced double-negative iNKT cell survival, but did not induce their expansion or production of cytokines. Notably, pDC-derived factors licensed iNKT cells to respond to myeloid DCs: an important downstream cellular target of iNKT cell effector function and a critical contributor to the initiation of adaptive immune responses. This interaction supports the notion that iNKT cells can mediate cross-talk between DC subsets known to express mutually exclusive TLR and cytokine profiles.

  18. Surface polyPEGylation of Eu3+ doped luminescent hydroxyapatite nanorods through the combination of ligand exchange and metal free surface initiated atom transfer radical polymerization

    The Eu3+ doped luminescent hydroxyapatite (HAp) nanorods with uniform size and morphology can be synthesized by hydrothermal route. However, these HAp nanorods are coated by hydrophobic oleylamine, which makes them difficult to be dispersed in aqueous solution and impede their biomedical applications. In this work, Eu3+ doped luminescent polymers functionalized HAp nanorods were prepared through the combination of ligand exchange reaction and metal free surface initiated atom transfer radical polymerization (ATRP) method. In this procedure, the amino group functionalized HAp nanorods were first prepared by ligand exchange reaction using adenosine monophosphate (AMP) as ligand. Then the Br-containing initiators (HAp-Br) were introduced onto the surface of HAp-AMP nanorods through the amidation reaction. Finally, polymers functionalized HAp nanorods were prepared by metal free ATRP method using poly(ethylene glycol) methacrylate (PEGMA) as monomer and 10-phenylphenothiazine (PTH) as organic photocatalyst. The properties of these obtained HAp nanocomposites (HAP-polyPEGMA nanorods) were characterized by means of transmission electron microscopy, Fourier transformed infrared spectroscopy, X-ray photoelectron spectroscopy and thermogravimetric analysis in detail. The cell imaging of these HAP-polyPEGMA nanorods was examined using laser scanning confocal microscope to evaluate their biomedical applications. We demonstrated for the first time that hydrophobic luminescent HAp nanorods can be functionalized with polyPEGMA through the combination of ligand exchange reaction and metal free surface initiated ATRP. As compared with the traditional ATRP, the metal free ATRP can overcome the toxic and fluorescence quenching effects of metal catalysts such as copper ions. More importantly, the strategy described in this work should also be utilized for fabrications of many other luminescent polymer nanocomposites due to its good monomer adoptability.

    Patient-support organizations can facilitate a significant change in the way rare disorders are approached. Besides connecting families with each other and directing patients to experienced medical specialists, these groups, by collaborating with government initiatives like COST, can effect the direction and funding of rare disease research. By concentrating the rare disease patient population and funneling them to specific centers of excellence, these organizations help build specialists' experience and their study populations. It requires a basic spirit of collaboration, driven parent leaders, a well-organized support platform, sources of funding, supportive clinical and research professionals and finally an effective method of collecting and disseminating information. Silver-Russell Syndrome is an excellent example of a rare disorder that has become better recognized, understood and treated because patient-support organizations, using the internet as a critical tool, have worked together with clinical care/research specialists and public funding agencies to build collaboration.

    Communication is made possible for disabled individuals by means of an electronic system, developed at Stanford University's School of Medicine, which produces highly intelligible synthesized speech. Familiarly known as the "talking wheelchair" and formally as the Versatile Portable Speech Prosthesis (VPSP). Wheelchair mounted system consists of a word processor, a video screen, a voice synthesizer and a computer program which instructs the synthesizer how to produce intelligible sounds in response to user commands. Computer's memory contains 925 words plus a number of common phrases and questions. Memory can also store several thousand other words of the user's choice. Message units are selected by operating a simple switch, joystick or keyboard. Completed message appears on the video screen, then user activates speech synthesizer, which generates a voice with a somewhat mechanical tone. With the keyboard, an experienced user can construct messages as rapidly as 30 words per minute.

    Conversational robots and agents are being designed for educational and/or persuasive tasks, e.g., health or fitness coaching. To pursue such tasks over a long time, they will need a complex model of the strategic goal, a variety of strategies to implement it in interaction, and the capability of strategic talk. Strategic talk is incipient ongoing conversation in which at least one participant has the objective of changing the other participant's attitudes or goals. The paper is based on the observation that strategic talk can stretch over considerable periods of time and a number of conversational segments. Film dialogues are taken as a source to develop a model of the strategic talk of mentor characters. A corpus of film mentor utterances is annotated on the basis of the model, and the data are interpreted to arrive at insights into mentor behavior, especially into the realization and sequencing of strategies.

    ABSTRACT Conversational robots and agents are being designed for educational and/or persuasive tasks, e.g., health or fitness coaching. To pursue such tasks over a long time, they will need a complex model of the strategic goal, a variety of strategies to implement it in interaction, and the capability of strategic talk. Strategic talk is incipient ongoing conversation in which at least one participant has the objective of changing the other participant’s attitudes or goals. The paper is based on the observation that strategic talk can stretch over considerable periods of time and a number of conversational segments. Film dialogues are taken as a source to develop a model of the strategic talk of mentor characters. A corpus of film mentor utterances is annotated on the basis of the model, and the data are interpreted to arrive at insights into mentor behavior, especially into the realization and sequencing of strategies.

    We reported a simple and efficient method to prepare the hydrophilic luminescent HAp polymer nanocomposites through the combination of ligand exchange and metal free light initiated surface-initiated atom transfer radical polymerization (SI-ATRP) using 10-phenylphenothiazine (PTH) as organic catalyst and 2-methacryloyloxyethyl phosphorylcholine (MPC) and itaconic acid (IA) as monomers. The biological imaging and drug delivery performance of HAp-poly(MPC-IA) nanorods were examined to evaluate their potential for biomedical applications. Results suggested that hydrophilic HAp-poly(MPC-IA) nanorods can be successfully prepared. More importantly, the HAp-poly(MPC-IA) exhibited excellent water dispersibility, desirable biocompatibility and good performance for biological imaging and controlled drug delivery applications. As compared with other controlled living polymerization reactions, the metal free light initiated SI-ATRP displayed many advantages such as easy for handle, mild reaction conditions, toxicity and fluorescence quenching from metal catalysts. Therefore, we believe that this strategy should be a useful and effective strategy for preparation of HAp nanomaterials for biomedical applications. Copyright © 2017 Elsevier B.V.

    PubMed Central

    Guina, Cathryn

    2018-01-01

    While post-stroke depression (PSD) is a common sequelae of stroke, many stroke survivors also have expressive aphasia (i.e., the inability to produce spoken or written language), which limits or prevents treating depression with talk psychotherapy. Unlike most psychotherapy modalities, eye movement desensitization and reprocessing (EMDR) does not require extensive verbal communication to therapists, which might make EMDR an ideal treatment modality for aphasic patients with mental health concerns. The authors present the first known case reporting EMDR in aphasia, describing the treatment of a 50-year-old woman with a history of depression following a left middle cerebral artery stroke. Left frontal lobe strokes are independently associated with both PSD and expressive aphasia. EMDR began two years following the stroke, at which point the patient continued to have persistent expressive aphasia despite previously completing more than a year of speech therapy. Using the Blind to Therapist Protocol, EMDR successfully led to improvement in depressive symptoms and, surprisingly, improvement in aphasia. This case report suggests that EMDR might be beneficial for those with mental health concerns who have expressive communication impairments that might prevent treatment with other psychotherapy modalities. We discuss potential challenges and technical workarounds with EMDR in aphasia, we speculate about potential biopsychosocial explanations for our results, and we recommend future research on EMDR for PSD and other mental health concerns in the context of aphasia, as well as possibly for aphasia itself.

    As a part of the European Union Naval Force - Mediterranean Operation Sophia (EUNAVFOR Med), the Federal Republic of Germany is contributing to avoid further loss of lives at sea by supplying two naval vessels. In the study presented here we analyse the medical requirements of such rescue missions, as well as the potential benefits of various additional monitoring devices in identifying sick/injured refugees within the primary onboard medical assessment process. Retrospective analysis of the data collected between May - September 2015 from a German Naval Force frigate. Initial data collection focused on the primary medical assessment and treatment process of refugees rescued from distress at sea. Descriptive statistics, uni- and multivariate analysis were performed. The study has received a positive vote from the Ethics Commission of the University of Ulm, Germany (request no. 284/15) and has been registered in the German Register of Clinical Studies (no. DRKS00009535). A total of 2656 refugees had been rescued. 16.9 % of them were classified as "medical treatment required" within the initial onboard medical assessment process. In addition to the clinical assessment by an emergency physician, pulse rate (PR), core body temperature (CBT) and oxygen saturation (SpO2) were evaluated. Sick/injured refugees displayed a statistically significant higher PR (114/min vs. 107/min; p < .001) and CBT (37.1 °C vs. 36.7 °C; p < .001). There was no statistically significant difference in SpO2-values. The same results were found for the subgroup of patients classified as "treatment at emergency hospital required". However, a much larger difference of the mean PR and CBT (35/min resp. 1.8 °C) was found when examining the subgroups of the corresponding refugee boats. A cut-off value of clinical importance could not be found. Predominant diagnoses have been dermatological diseases (55.4), followed by internal diseases (27.7) and trauma (12.1 %). None of the refugees

  4. Learning to talk

    2004-05-01

    Is imitation a necessary part of learning to talk? The faithful replication by children of such arbitrary phenomena of English as tense and lax vowel properties, ``rhythm,'' and context-dependent VOT's seems to insist that it is. But a nonimitative account of this is also possible. It relies on two principal mechanisms. First, basic speech sounds are learned by emulation: attempting to reproduce the results achieved by other speakers but without copying their actions to do so. The effectiveness of the output provides sufficient feedback to inform the child of the adequacy of its performance and to guide refinement. Second, phonetic phenomena such as those above appear through aerodynamic accommodation. Key elements of this are (a) that speech breathing is a complex motor skill which dominates other articulatory processes during acquisition and starts pulsatile before becoming smooth, and (b) that a child-scale production system imposes constraints on talking which do not operate in the adult speaker. Much of ``the terrible complexity of phonetic patterns'' [J. Pierrehumbert, Lang. Speech 46, 115-154 (2003)] then becomes epiphenomenal: appearing not as a result of young learners copying phonetic detail that is not linguistically significant, but of them reconciling conflicting production demands while just talking.

    Using a mixed-methods study, we provided the first systematic documentation and exploration of erotic talk. In Study 1 (N = 95), participants provided 569 erotic talk statements in an anonymous online survey, which we classified, using a modified thematic analysis, as being representative of eight themes. In Study 2 (N = 238), we quantified individual differences in these themes, subjected them to factor analysis, and examined the nomological network surrounding them with measures of relationship and sexual satisfaction, sociosexuality, and personality. The eight initial categories represented two higher order factors, which we call individualist talk and mutualistic talk. These factors were orthogonal in factor analysis and distinct in their nomological network. While the majority of people reported using erotic talk, we found few sex differences in its use.

In Hot Talk, Cold Science, S. Fred Singer does not accept global warming. Singer says in his preface, “The purpose of this book is to demonstrate that the evidence [for global warming] is neither settled, nor compelling, nor even convincing. On the contrary, scientists continue to discover new mechanisms for climate change and to put forth new theories to try to account for the fact that global temperature is not rising, even though greenhouse theory says it should”.

In colloid science, computer simulations that started out as studies of highly simplified model systems, have acquired direct experimental relevance because experimental realizations of these simple models can now be synthesized. Whilst many numerical predictions concerning the phase behavior of colloidal systems have been vindicated by experiments, the jury is still out on others. In my talk I will discuss some of the recent technical developments, new findings and open questions in computational soft-matter science.

  10. Quantifying athlete self-talk.

    2005-09-01

    Two studies were conducted. The aims of Study 1 were (a) to generate quantitative data on the content of athletes' self-talk and (b) to examine differences in the use of self-talk in general as well as the functions of self-talk in practice and competition settings. Differences in self-talk between the sexes, sport types and skill levels were also assessed. Athletes (n = 295, mean age = 21.9 years) from a variety of sports and competitive levels completed the Self-Talk Use Questionnaire (STUQ), which was developed specifically for the study. In Study 1, single-factor between-group multivariate analyses of variance revealed significant differences across sex and sport type for the content of self-talk. Mixed-model multivariate analyses of variance revealed overall greater use of self-talk, as well as increased use of the functions of self-talk, in competition compared with practice. Moreover, individual sport athletes reported greater use of self-talk, as well as the functions of self-talk, than their team sport counterparts. In Study 2, recreational volleyball players (n = 164, mean age = 21.5 years) completed a situationally modified STUQ. The results were very similar to those of Study 1. That the content of athlete self-talk was generally positive, covert and abbreviated lends support to the application of Vygotsky's (1986) verbal self-regulation theory to the study of self-talk in sport. Researchers are encouraged to examine the effectiveness of self-talk in future studies.

    The memoirs of the author traces his life from his first-year graduate studies in physics at the University of Rochester in 1942 to his present position as Director of the University of California's Institute on Global Conflict and Cooperation. The part of his life involved in making weapons extends from 1942 to 1961. During this period, he worked with E.O. Lawrence on the Manhattan Project and served as director of Livermore after it became the Atomic Energy Commission's second nuclear weapons laboratory. He also served on many government advisory boards and commissions dealing with nuclear and other weapons. In 1961,more » the combination of a heart attack and changes in administration in Washington led York too return to the University of California for the talking peace portion of his life. He has since become a public exponent of arms control and disarmament and the futility of seeking increased security through more and better nuclear weapons.

    Peer education is an important component of residency training and it generally takes the form of informal discussions. Residents may also prepare more formal presentations for their peers and analysing the topics they choose to address can serve as a form of needs assessment by giving faculty insight into the content they believe should be taught. At our internal medicine residency program, interns participating in an evidence-based medicine rotation make a formal 30-minute presentation on the topic of their choosing. We reviewed the Power Point slides from 88 presentations given over the past 6 years and have characterized the topics that were covered. Many of the talks were innovative and dealt with subject matter not covered elsewhere in the residency curriculum. Providing housestaff with more opportunities to formally teach each other may improve the educational experience of residency training.

    2016-01-01

    Campaign-stimulated conversations have been shown to increase the effectiveness of antismoking campaigns. In order to explore why such effects occur, in the current study we coded the content of naturally occurring conversations. We also examined whether the short-term effects of talking, and of different types of talk, on quitting intentions were mediated through intrapersonal message responses. Using the Natural Exposure(SM) methodology, we exposed 411 smokers to 1 of 6 antismoking advertisements while they were watching television at home. Responses to the advertisement-conversation participation and content, emotional responses, personalized perceived effectiveness, and changes in intentions to quit-were measured within 3 days of exposure. Conversations were coded for appraisal of the advertisement (favorable, neutral, or unfavorable) and the presence of quitting talk and emotion talk. Mediation analyses indicated that the positive effects of talking on intention change were mediated through personalized perceived effectiveness and that the positive effects were driven by conversations that contained a favorable appraisal and/or quitting talk. Conversely, conversations that contained an unfavorable appraisal of the advertisement were negatively associated with campaign effectiveness. These findings highlight the importance of measuring interpersonal communication when evaluating campaigns and the need for further research to identify the message characteristics that predict when smokers talk and when they talk only in desirable ways.

  20. On talking-as-dreaming.

    PubMed

    Ogden, Thomas H

    2007-06-01

    Many patients are unable to engage in waking-dreaming in the analytic setting in the form of free association or in any other form. The author has found that "talking-as-dreaming" has served as a form of waking-dreaming in which such patients have been able to begin to dream formerly undreamable experience. Such talking is a loosely structured form of conversation between patient and analyst that is often marked by primary process thinking and apparent non sequiturs. Talking-as-dreaming superficially appears to be "unanalytic" in that it may seem to consist "merely" of talking about such topics as books, films, etymology, baseball, the taste of chocolate, the structure of light, and so on. When an analysis is "a going concern," talking-as-dreaming moves unobtrusively into and out of talking about dreaming. The author provides two detailed clinical examples of analytic work with patients who had very little capacity to dream in the analytic setting. In the first clinical example, talking-as-dreaming served as a form of thinking and relating in which the patient was able for the first time to dream her own (and, in a sense, her father's) formerly unthinkable, undreamable experience. The second clinical example involves the use of talking-as-dreaming as an emotional experience in which the formerly "invisible" patient was able to begin to dream himself into existence. The analyst, while engaging with a patient in talking-as-dreaming, must remain keenly aware that it is critical that the difference in roles of patient and analyst be a continuously felt presence; that the therapeutic goals of analysis be firmly held in mind; and that the patient be given the opportunity to dream himself into existence (as opposed to being dreamt up by the analyst).

    A literacy-related activity that occurs in children's homes—talk about letters in everyday conversations—was examined using data from 50 children who were visited every 4 months between 14 and 50 months. Parents talked about some letters, including those that are common in English words and the first letter of their children's names, especially often. Parents’ focus on the child's initial was especially strong in families of higher socioeconomic status, and the extent to which parents talked about the child's initial during the later sessions of the study was related to the children's kindergarten reading skill. Conversations that included the child's initial were longer than those that did not, and parents presented a variety of information about this letter. PMID:26014495

  6. A project in Zambia: talking to children about AIDS.

    PubMed

    Baker, K

    1988-09-01

    Early in 1987, it became clear to this individual that children were a high priority group for Acquired Immune Deficiency Syndrome (AIDS) education. Preparation for providing AIDS education in Zambia included reading as much as possible about AIDS and AIDS education in schools, contacting the Health Education Unit at the Ministry of Health for their permission and advice, and making posters and preparing a list of 10 basic questions about AIDS. The 1st talks were at a boys' technical school and a large girls' day school. Following an introduction of the subject, the format included: a 10-minute quiz with students writing down their answers; a 35-40 minute talk, using posters as visual aids; a 20-30 minute open question time; and a repeat of the same quiz as a form of "posttest." The students responded positively, and there was a substantial increase in the percentage of correct answers after each talk. Subsequently, talks were given in other Lusaka secondary schools. After the 1st few talks, the pretest and posttest was discontinued as it was considered preferable to spend more time answering the students' questions. The talks varied depending on the audience, but posters were always included as visual aids. Initially, this AIDS education effort was voluntary and unfunded. Subsequently, and as the work grew, NORAD funded the project, paying for duplicating and printing as well as a salary on an hourly basis. A booklet on AIDS for secondary schools has been written and duplicated and accepted by the Intersectorial Committee on AIDS Health Education with minor changes. Late in 1987, the booklet was rewritten totally and expanded, with numerous illustrations. Throughout the booklet, human immunodeficiency virus (HIV) is carefully differentiated from AIDS disease. Talks also have been initiated at the Upper Primary School level. The format has been altered somewhat for these younger children as they tend to be noisy and excited. The primary project planned for 1988 is

  7. The smart-talk trap.

    PubMed

    Pfeffer, J; Sutton, R I

    1999-01-01

    In today's business world, there's no shortage of know-how. When companies get into trouble, their executives have vast resources at their disposal: their own experiences, colleagues' ideas, reams of computer-generated data, thousands of publications, and consultants armed with the latest managerial concepts and tools. But all too often, even with all that knowledge floating around, companies are plagued with an inertia that comes from knowing too much and doing too little--a phenomenon the authors call the knowing-doing gap. The gap often can be traced to a basic human propensity: the willingness to let talk substitute for action. When confronted with a problem, people act as though discussing it, formulating decisions, and hashing out plans for action are the same as actually fixing it. And after researching organizations of all shapes and sizes, the authors concluded that a particular kind of talk is an especially insidious inhibitor of action: "smart talk." People who can engage in such talk generally sound confident and articulate; they can spout facts and may even have interesting ideas. But such people often exhibit the less benign aspects of smart talk as well: They focus on the negative, and they favor unnecessarily complex or abstract language. The former lapses into criticism for criticism's sake; the latter confuses people. Both tendencies can stop action in its tracks. How can you shut the smart-talk trap and close the knowing-doing gap? The authors lay out five methods that successful companies employ in order to translate the right kind of talk into intelligent action.

  8. Toy talk: simple strategies to create richer grammatical input.

    PubMed

    Hadley, Pamela A; Walsh, Kathleen M

    2014-07-01

    The purpose of this initial feasibility study was to determine whether brief instruction in toy talk would change grammatical properties of adult language, specifically 3rd person lexical noun phrase (NP) subjects. Eighteen college students participated in the study. The use of 3rd person subjects was examined before and after instruction on toy talk strategies (i.e., talk about the toys, give the item its name). Change in the input informativeness for tense (i.e., the proportion of verb forms marked for tense out of all verb forms) was also examined, although adults were not instructed on use of tense/agreement morphemes. Following instruction, statistically significant increases with large effect sizes were observed for use of 3rd person subjects, lexical NP subjects, and input informativeness for tense (Cohen's d = 1.20, 2.08, and 0.89, respectively). These findings demonstrate that young adults can learn these simple strategies with relatively brief instruction, and the use of toy talk also changes the richness of tense/agreement marking in adult language input. Considerations for incorporating toy talk into existing language modeling practices and future plans for evaluating the efficacy of toy talk are discussed.

    Lombardi, Diana R; Button, Melissa L; Westra, Henny A

    2014-01-01

    How clients talk about change early in treatment has been found to be a potent predictor of their subsequent treatment success. Studies examining such client motivational language (arguments for and against change) have typically been conducted in the context of motivational interviewing for addictions. This study examined the capacity of client motivational language to predict treatment outcomes in the context of cognitive behavioral therapy (CBT) for generalized anxiety. Client early in-session statements against change (counter-change talk) were found to be robust predictors of post-treatment worry scores and differentiated treatment responders from nonresponders. Moreover, client motivational language predicted outcomes beyond initial symptom severity and self-report measures of motivation. These results strongly support the relevance of client motivational language outcomes in CBT and provide a foundation for advancing research on motivation for change in a CBT context.

  17. Frequency and Efficacy of Talk-Related Tasks in Primary Science

    NASA Astrophysics Data System (ADS)

    Braund, Martin; Leigh, Joanne

    2013-04-01

    Pupil talk and discussion are seen as having important social and cognitive outcomes. In science classes, pupils' collaborative talk supports the construction of meaning and helps examine the status of evidence, theory and knowledge. However, pupil interactive talk in groups is rare in science lessons. The research reported is part of a project to increase the amount of pupil-pupil talk in primary schools through a programme of teaching and professional development. Pupils' self-reports of the frequency and learning efficacies of talk related activities in science lessons were collected before and after a programme of teaching in 24 schools in one of the most socially and educationally deprived areas of England. Findings showed pupils valued talking about their ideas over listening to those of other pupils. Science talk frequency (STF) was closely correlated with science talk efficacy (STE) and both were positively correlated with pupils' attitudes to school science. Analysis of covariance (ANCOVA) of the correlation of STF with STE showed values were independent of gender and ability but that school experience was a significant factor. After the teaching programme and, contrary to expectations, the frequency of talk activities in science lessons appeared to have decreased but varied according to class grades. The degree of correlation between STF and STE was stronger after the teaching in over half of the schools. Schools where STF/STE strengthened most as a result of teaching were those involved in an additional initiative to use modelled talk related to industrial contexts.

    We discuss the theoretical aspects of core-to-core power transfer in multicore fibers relying on supermode theory. Based on a dual core fiber model, we investigate the consequences of this approach, such as the influence of initial excitation conditions on cross talk. Supermode interpretation of power coupling proves to be intuitive and thus may lead to new concepts of multicore fiber-based devices. As a conclusion, we propose a definition of a uniform cross talk parameter that describes multicore fiber design.

    With constant incentives for healthcare payers to contain their pharmaceutical budgets, forecasting has become critically important. Some countries have, for instance, developed pharmaceutical horizon scanning units. The objective of this project was to build a model to assess the net effect of the entrance of new patented medicinal products versus medicinal products going off-patent, with a defined forecast horizon, on selected European Union (EU) Member States' pharmaceutical budgets. This model took into account population ageing, as well as current and future country-specific pricing, reimbursement, and market access policies (the project was performed for the European Commission; see http://ec.europa.eu/health/healthcare/key_documents/index_en.htm). In order to have a representative heterogeneity of EU Member States, the following countries were selected for the analysis: France, Germany, Greece, Hungary, Poland, Portugal, and the United Kingdom. A forecasting period of 5 years (2012-2016) was chosen to assess the net pharmaceutical budget impact. A model for generics and biosimilars was developed for each country. The model estimated a separate and combined effect of the direct and indirect impacts of the patent cliff. A second model, estimating the sales development and the risk of development failure, was developed for new drugs. New drugs were reviewed individually to assess their clinical potential and translate it into commercial potential. The forecast was carried out according to three perspectives (healthcare public payer, society, and manufacturer), and several types of distribution chains (retail, hospital, and combined retail and hospital). Probabilistic and deterministic sensitivity analyses were carried out. According to the model, all countries experienced drug budget reductions except Poland (+€41 million). Savings were expected to be the highest in the United Kingdom (-€9,367 million), France (-€5,589 million), and, far behind them

    Estigarribia, Bruno; Clark, Eve V

    2007-11-01

    When two people talk about an object, they depend on joint attention, a prerequisite for setting up common ground in a conversational exchange. In this study, we analyze this process for parent and child, with data from 40 dyads, to show how adults initiate joint attention in talking to young children (mean ages 1;6 and 3;0). Adults first get their children's attention with a summons (e.g. Ready?, See this?), but cease using such forms once children give evidence of attending. Children signal their attention by looking at the target object, evidence used by the adults. Only at that point do adults begin to talk about the object. From then on, they use language and gesture to offer information about and maintain attention on the target. The techniques adults rely on are interactive: they establish joint attention and maintain it throughout the exchange.

    Since the start of the economic crisis, the European Union's (EU's) predominant discourse has been austerity and fiscal consolidation. The detrimental effects on Europe's health systems and the health status of its citizens are well described. However, little is known about the emerging EU-level initiatives to support national health systems handle the challenges of efficient care provision and system reorganisation aimed to meet their future needs. This review analyses the manner, conditions and prospects of such EU support. First, health system objectives are increasingly entering the EU health policy agenda. Second, professional and patient mobility provisions may support member states (MS) in copying with crisis related health challenges but can potentially acerbate them at the same time. Third, in recent initiatives health system goals are more closely tied to the EU's economic growth narrative. And fourth, health system issues are taken up in existing EU-level structures for debate and exchange between MS. In addition, the design of some policies may have the potential to intensify socioeconomic and health inequalities rather than ameliorate them.

    2017-01-01

    Objectives To revise an existing three-talk model for learning how to achieve shared decision making, and to consult with relevant stakeholders to update and obtain wider engagement. Design Multistage consultation process. Setting Key informant group, communities of interest, and survey of clinical specialties. Participants 19 key informants, 153 member responses from multiple communities of interest, and 316 responses to an online survey from medically qualified clinicians from six specialties. Results After extended consultation over three iterations, we revised the three-talk model by making changes to one talk category, adding the need to elicit patient goals, providing a clear set of tasks for each talk category, and adding suggested scripts to illustrate each step. A new three-talk model of shared decision making is proposed, based on “team talk,” “option talk,” and “decision talk,” to depict a process of collaboration and deliberation. Team talk places emphasis on the need to provide support to patients when they are made aware of choices, and to elicit their goals as a means of guiding decision making processes. Option talk refers to the task of comparing alternatives, using risk communication principles. Decision talk refers to the task of arriving at decisions that reflect the informed preferences of patients, guided by the experience and expertise of health professionals. Conclusions The revised three-talk model of shared decision making depicts conversational steps, initiated by providing support when introducing options, followed by strategies to compare and discuss trade-offs, before deliberation based on informed preferences.

    Objectives  To revise an existing three-talk model for learning how to achieve shared decision making, and to consult with relevant stakeholders to update and obtain wider engagement. Design  Multistage consultation process. Setting  Key informant group, communities of interest, and survey of clinical specialties. Participants  19 key informants, 153 member responses from multiple communities of interest, and 316 responses to an online survey from medically qualified clinicians from six specialties. Results  After extended consultation over three iterations, we revised the three-talk model by making changes to one talk category, adding the need to elicit patient goals, providing a clear set of tasks for each talk category, and adding suggested scripts to illustrate each step. A new three-talk model of shared decision making is proposed, based on "team talk," "option talk," and "decision talk," to depict a process of collaboration and deliberation. Team talk places emphasis on the need to provide support to patients when they are made aware of choices, and to elicit their goals as a means of guiding decision making processes. Option talk refers to the task of comparing alternatives, using risk communication principles. Decision talk refers to the task of arriving at decisions that reflect the informed preferences of patients, guided by the experience and expertise of health professionals. Conclusions  The revised three-talk model of shared decision making depicts conversational steps, initiated by providing support when introducing options, followed by strategies to compare and discuss trade-offs, before deliberation based on informed preferences.

  6. A System of Systems Approach to the EU Energy System

    NASA Astrophysics Data System (ADS)

    Jess, Tom; Madani, Kaveh; Mahlooji, Maral; Ristic, Bora

    2016-04-01

    Around the world, measures to prevent dangerous climate change are being adopted and may change energy systems fundamentally. The European Union (EU) is committed to reducing greenhouse gas emission by 20% by 2020 and by 80-95% by 2050. In order to achieve this, EU member states aim to increase the share of renewables in the energy mix to 20% by 2020. This commitment comes as part of a series of other aims, principles, and policies to reform the EU's energy system. Cost-efficiency in the emissions reductions measures as well as strategic goals under the Resource Efficient Europe flagship initiative which would include a more prudent approach to other natural resources such as water and land. Using the "System of Systems Approach", as from Hadian and Madani (2015), energy sources' Relative Aggregate Footprints (RAF) in the EU are evaluated. RAF aggregates across four criteria: carbon footprint, water footprint, land footprint, and economic cost. The four criteria are weighted by resource availability across the EU and for each Member State. This provides an evaluation of the overall resource use efficiency of the EU's energy portfolio and gives insight into the differences in the desirability of energy sources across Member States. Broadly, nuclear, onshore wind, and geothermal are most desirable under equal criteria weights and EU average weighting introduces only small changes in the relative performance of only few technologies. The member state specific weightings show that most countries have similar energy technology preferences. However, the UK deviates most strongly from the average, with an even stronger preference for nuclear and coal. Sweden, Malta and Finland also deviate from the typical preferences indicating the complexity in play in reforming the EU energy system.

Hence, a gradual approach based on pilot initiatives and selective collaboration would be advisable initially, which could be expanded once there is demonstrated evidence on outcomes. Overall, the paper makes a contribution to the social science and health literature by adding to the limited primary evidence base on globalization and health, especially from a developing-developed country and regional perspective.

    In this secondary analysis of videotape data, we describe birth talk demonstrated by caregivers to women during the second stage of labor. Birth talk is a distinctive verbal register or a set of linguistic features that are used with particular behaviors during specific situations, has a particular communication purpose, and is characterized by distinctive language features. Birth talk is found cross-culturally among speakers of diverse languages. Our findings show that birth talk occurred mainly during contractions and co-occurred with two general styles of caregiving: "directed toward forced bearing down" and "supportive of physiologic bearing down." We also describe talk that occurred during rest periods, which was similar across the two styles. Caregivers' use of language tended to be either procedural (giving directions, instructions) or comfort related (encouraging and supporting). Linguistic features of the talk consisted of utterances of short duration, level pitch patterns with no sudden pitch shifts, and a restricted pitch range.

  14. "Eugenics talk" and the language of bioethics.

    PubMed

    Wilkinson, S

    2008-06-01

    In bioethical discussions of preimplantation genetic diagnosis and prenatal screening, accusations of eugenics are commonplace, as are counter-claims that talk of eugenics is misleading and unhelpful. This paper asks whether "eugenics talk", in this context, is legitimate and useful or something to be avoided. It also looks at the extent to which this linguistic question can be answered without first answering relevant substantive moral questions. Its main conclusion is that the best and most non-partisan argument for avoiding eugenics talk is the Autonomy Argument. According to this, eugenics talk per se is not wrong, but there is something wrong with using its emotive power as a means of circumventing people's critical-rational faculties. The Autonomy Argument does not, however, tell against eugenics talk when such language is used to shock people into critical-rational thought. These conclusions do not depend on unique features of eugenics: similar considerations apply to emotive language throughout bioethics.

  15. Talk radio as the soundtrack of our lives: Participatory HIV/AIDS communication, public self-expression and Positive Talk.

    PubMed

    Burger, Mariekie

    2015-01-01

    Despite the many HIV/AIDS communication initiatives, combined with support and infrastructural support in South Africa, risky behaviour associated with the spread of the epidemic is increasing amongst many groups. This calls for a re-evaluation of endeavours aimed at curbing the spread of the epidemic. This article is only concerned with the communicational aspects of the epidemic, but does not negate the interaction of these with other measures taken to address the epidemic. As is the case with most health communication initiatives, HIV/AIDS communication initiatives have evolved to favour the participatory approach above one-directional transmission of information to the public. The participatory approach rests on the assumption that an HIV/AIDS communication initiative stands the best chance of resulting in behaviour change if members of the target community participate in the communication initiative. The assumption is that as many people as possible should be involved in the maximum number of phases of the communicative initiative (such as initial research, planning, implementation and evaluation of the project). Some research has recently started to explore new forms of community participation, including inviting community participation through, for example, internet-based platforms such as social media, and mobile phone platforms such as WhatsApp and BBM. However, the reality broadcast genre--more specifically, talk radio--has been neglected, as only a few research investigations focused on talk radio and most of these are not exclusively about HIV/AIDS communication but focus on other health topics. From a participatory communication perspective, two sets of critique against the existing HIV/AIDS communication projects hold water: firstly, they do not make the maximum use of participatory communication principles and, secondly, they are externally initiated projects and emanate from outside the target community. To address both of these concerns, this

    2014-04-01

    This article focuses on the relevance that the dimension of the future has for promoting healthy and active aging. Older people generally have difficulties in talking about the future and when they do they generally express very negative perspectives on it. The data analyzed in this paper are part of an on-going interdisciplinary research project: "Aging, poverty and social exclusion: an interdisciplinary study on innovative support services" (https://apseclunl.wordpress.com/). The project aims at documenting good practices in social intervention with older people who are at risk of exclusion. This study describes and critically discusses an activity carried out in Portugal among older women in a poor area in the suburb of Lisbon entitled "self-awareness workshop on the future". Through a detailed discourse analysis within an ethnomethodological framework the study shows age membership categorizations in use and categorization processes, examining the workshop interaction. In particular, the article describes how the psychologist works at deconstructing and problematizing the negative connotations related to age membership categories. Taking into consideration the interactionally constructed nature of aging and the material consequences that different attitudes towards aging can imply is very important in particular in relation to the provision of services to older people.

  17. Do manatees talk during sex?

    NASA Astrophysics Data System (ADS)

    Self-Sullivan, Caryn; Gilbertson, Tamra; Evans, William E.

    2002-05-01

    On January 13, 1999, manatee vocalizations were recorded during a mating herd event in the Orange River, Florida. Although copulation could not be observed, multiple males were observed with exposed penises. During one 25 min sample (1300-1325 h), over 400 manatee signals were recorded. In March 2000, each signal was captured and digitized from the analog tape using a Marantz PMD 501, Ashly equalizer (gain=0, filter=0), MAC 8100, and Canary 1.2.1. In general, signals were 100-200 ms in length, highly harmonic (up to 8 harmonics ranging from 1 to 16 kHz), with little or no frequency modulation. Intervals between signals ranged from less than 1 s to 14 s (mean = 3 s), indicating that manatees do indeed talk (a lot) during sex. Noise from two passing boats was also recorded during the sample period. One abnormally low-frequency signal (0.4 kHz) was recorded during one boat pass. This apparent manatee vocalization could be seen and heard below the boat noise frequency band.

  18. Stakeholder integration and public engagement of EU and national research projects in Germany

    2017-04-01

    The talk addresses the feasibility and difficulties of research projects to reach out and to integrate a sufficient number of stakeholders (vgl. Carrada, 2006; Poulsen, 2007; Zikos et al. 2012; Lee & Belohlav, 2014). With "stakeholders" we understand end-users, policy makers, students for capacity building, administrators and interested general public. The design and later the implementation of stakeholder integration and public engagement strongly depend on the priority-setting and requirements of funding agencies (EU [1], DFG, BMBF and the regional ministries in Germany). They affect the size and constellation of consortia as well as the longevity and continuity of research community; on the other hand they also determine the weighting of communication, dissemination, outreach (and networking) activities within the project. For instance by public engagement of EU funded projects a share of 10% for communication and outreach activities was rated as best practices in 2014 [2]. On the national level there is no such appointment so far. In our talk we will quantify and compare activities among selected EU and nationally funded collaborative projects in Germany, address the hurdles, investigate the communication tools, examine the outreach channels and dissemination tactics, reflect the performances and the results achieved so far, with the objective to answer the following questions: - What tools/channels have been applied so far? Were they efficient and expedient? - What can be count as best practices? - Are such activities sustainable at all? The goal of this talk is to show the complexity of the stakeholder integration and public engagement in research projects, to critically assess our experiences gained in past and running projects, and to subsequently have an interactive exchange with other project professionals at EGU.

    To identify individual therapist behaviors which elicit client change talk or sustain talk in motivational interviewing sessions. Motivational interviewing sessions from a single-session alcohol intervention delivered to college students were audio-taped, transcribed, and coded using the Motivational Interviewing Skill Code (MISC), a therapy process coding system. Participants included 92 college students and eight therapists who provided their treatment. The MISC was used to code 17 therapist behaviors related to the use of motivational interviewing, and client language reflecting movement toward behavior change (change talk), away from behavior change (sustain talk), or unrelated to the target behavior (follow/neutral). Client change talk was significantly more likely to immediately follow individual therapist behaviors [affirm (p=.013), open question (p<.001), simple reflection (p<.001), and complex reflection (p<.001)], but significantly less likely to immediately follow others (giving information (p<.001) and closed question (p<.001)]. Sustain talk was significantly more likely to follow therapist use of open questions (p<.001), simple reflections (p<.001), and complex reflections (p<.001), and significantly less likely to occur following therapist use of therapist affirm (p=.012), giving information (p<.001), and closed questions (p<.001). Certain individual therapist behaviors within motivational interviewing can either elicit both client change talk and sustain talk or suppress both types of client language. Affirm was the only therapist behavior that both increased change talk and also reduced sustain talk. Copyright © 2015 Elsevier Inc. All rights reserved.

  1. Strong Eu2+ light emission in Eu silicate through Eu3+ reduction in Eu2O3/Si multilayer deposited on Si substrates

    PubMed Central

    2013-01-01

    Eu2O3/Si multilayer nanostructured films are deposited on Si substrates by magnetron sputtering. Transmission electron microscopy and X-ray diffraction measurements demonstrate that multicrystalline Eu silicate is homogeneously distributed in the film after high-temperature treatment in N2. The Eu2+ silicate is formed by the reaction of Eu2O3 and Si layers, showing an intense and broad room-temperature photoluminescence peak centered at 610 nm. It is found that the Si layer thickness in nanostructures has great influence on Eu ion optical behavior by forming different Eu silicate crystalline phases. These findings open a promising way to prepare efficient Eu2+ materials for photonic application. PMID:23618344

    Eu-doped 70SiO2–23HfO2–7ZnO (mol%) glass-ceramic waveguides have been fabricated by sol-gel method as a function of heat-treatment temperatures for on-chip blue-light emitting source applications. Structural evolution of spherical ZnO and spherical as well as rod-like HfO2 nanocrystalline structures have been observed with heat-treatments at different temperatures. Initially, in the as-prepared samples at 900 ◦C, both, Eu2+ as well as Eu3+ ions are found to be present in the ternary matrix. With controlled heat-treatments of up to 1000 ◦C for 2 h, local environment of Eu-ions become more crystalline in nature and the reduction of Eu3+ to Eu2+ takes place in such ZnO/HfO2 crystalline environments. In these ternary glass-ceramic waveguides, heat-treated at higher temperatures, the blue-light emission characteristic, which is the signature of 4f 65d \\to 4f 7 energy level transition of Eu2+ ions is found to be greatly enhanced. The as-prepared glass-ceramic waveguides exhibit a propagation loss of 0.4 ± 0.2 dB cm‑1 at 632.8 nm. Though the propagation losses increase with the growth of nanocrystals, the added functionalities achieved in the optimally heat-treated Eu-doped 70SiO2–23HfO2–7ZnO (mol%) waveguides, make them a viable functional optical material for the fabrication of on-chip blue-light emitting sources for integrated optic applications.

  3. Talking Cure Models: A Framework of Analysis

    PubMed Central

    Marx, Christopher; Benecke, Cord; Gumz, Antje

    2017-01-01

    Psychotherapy is commonly described as a “talking cure,” a treatment method that operates through linguistic action and interaction. The operative specifics of therapeutic language use, however, are insufficiently understood, mainly due to a multitude of disparate approaches that advance different notions of what “talking” means and what “cure” implies in the respective context. Accordingly, a clarification of the basic theoretical structure of “talking cure models,” i.e., models that describe therapeutic processes with a focus on language use, is a desideratum of language-oriented psychotherapy research. Against this background the present paper suggests a theoretical framework of analysis which distinguishes four basic components of “talking cure models”: (1) a foundational theory (which suggests how linguistic activity can affect and transform human experience), (2) an experiential problem state (which defines the problem or pathology of the patient), (3) a curative linguistic activity (which defines linguistic activities that are supposed to effectuate a curative transformation of the experiential problem state), and (4) a change mechanism (which defines the processes and effects involved in such transformations). The purpose of the framework is to establish a terminological foundation that allows for systematically reconstructing basic properties and operative mechanisms of “talking cure models.” To demonstrate the applicability and utility of the framework, five distinct “talking cure models” which spell out the details of curative “talking” processes in terms of (1) catharsis, (2) symbolization, (3) narrative, (4) metaphor, and (5) neurocognitive inhibition are introduced and discussed in terms of the framework components. In summary, we hope that our framework will prove useful for the objective of clarifying the theoretical underpinnings of language-oriented psychotherapy research and help to establish a more comprehensive

  5. From Shell Shock to Shellac: The Great War, Blindness, and Britain's Talking Book Library.

    PubMed

    Rubery, Matthew

    2015-01-01

    Britain's Talking Book Service began as a way of providing reading material to soldiers blinded during the First World War. This account traces the talking book's development from the initial experiments after the War to its debut and reception among blind soldiers and civilians in the 1930s. It has been put together using archives held by the Royal National Institute of Blind People (before its Royal Charter, the NIB) and Blind Veterans UK (formerly St. Dunstan's), the two organizations responsible for Britain's Talking Book Service. The essay's first section reconstructs the search for an alternative way of reading that would benefit people with vision impairments. The next part demonstrates the talking book's impact on the lives of people with disabilities, recovering the voices of blind readers left out of most histories of books, literacy, and reading practices in the twentieth century. The final section reconstructs a debate over the value of recorded books, showing that disputes over their legitimacy are as old as recorded books themselves. In sum, this essay confronts the central issue raised by the convergence of books, media, and disability in the War's aftermath: can a book talk?

  6. Talking about sex in the gender identity clinic: implications for training and practice.

    PubMed

    Speer, Susan A

    2013-11-01

    This article provides the first systematic examination of the ways 'talk about sex' is occasioned and managed by doctors and patients in real-life interactions in a National Health Service Gender Identity Clinic. Drawing on a corpus of 194 recordings of psychiatric assessment sessions, the article examines how parties initiate and develop talk about sex, and which strategies appear to work best for doctor-patient alignment. The analyses revealed that the most aligning methods were for clinicians to make transitions from asking questions about relationships in general to talk about sex, or to build opportunistically on patients' relationship talk. However, talk about sex that lacked specificity or which made inaccurate presumptions about patients' sex lives, generated misalignment between clinician and patient. I suggest that such misalignment is not intrinsically bad. Rather, it provides evidence for the virtues of a more nuanced understanding of patient-centred communication. The article concludes with a discussion of the importance of grounding communication skills training and clinical practice in recordings of actual consultations.

  8. Emerging food safety issues: An EU perspective.

    PubMed

    McEvoy, John D G

    2016-05-01

    Safe food is the right of every citizen of the European Union (EU). A comprehensive and dynamic framework of food and feed safety legislation has been put in place and the EU's executive arm - the European Commission - is responsible for ensuring that the EU member states apply food law consistently. Similarly, the Commission plays an important role in ensuring that imported food meets the EU's stringent food safety standards. Consumer perceptions of unsafe food tend to focus on acute outbreaks of bacterial or viral origin. In recent years there have been a number of diverse food crises associated with fraudulent activity which may (e.g. melamine in dairy products in China) or may not (e.g. the horse meat scandal in the EU) represent a genuine food safety risk. Well publicized incidents of chronic exposure to chemical contamination in the EU (e.g. dioxins in meat and mycotoxins in nuts) have required robust coordinated policy responses from the Commission. Despite the decreasing incidence of non-compliant residues of veterinary medicinal products and banned substances in animal products, EU consumers are increasingly concerned about the use of such products in food-producing animals, including in the context of the build-up of antimicrobial resistance in animals and transfer to humans. The Commission plays a key role in coordination of the EU member states' responses to such incidents, in risk management, and in preparation for emerging issues. This paper focuses on how the EU as a whole has dealt with a number of food crises, and what can be learned from past incidents. Copyright © 2016 John Wiley & Sons, Ltd.

    2015-04-01

    A talk addressing workload, focuses, impacts and outcomes of project management (hereinafter PM) Two FP7 projects serve as objects for investigation. In the Earth Science sector NACLIM is a large scale collaborative project with 18 partners from North and West Europe. NACLIM aims at investigating and quantifying the predictability of the North Atlantic/Arctic sea surface temperature, sea ice variability and change on seasonal to decadal time scales which have a crucial impact on weather and climate in Europe. PRIMO from Political Science is a global PhD program funded by Marie Curie ITN instrument with 11 partners from Europe, Eurasia and BRICS countries focusing on the rise of regional powers and its impact on international politics at large. Although the two projects are granted by different FP7 funding instruments, stem from different cultural backgrounds and have different goals, the inherent processes and the key focus of the PM are quite alike. Only the operational management is at some point distinguished from one another. From the administrative point of view, understanding of both EU requirements and the country-specific regulations is essential; it also helps us identifying the grey area in order to carry out the projects more efficiently. The talk will focus on our observation of the day-to-day PM flows - primarily the project implementation - with few particular cases: transparency issues, e.g. priority settings of non-research stakeholders including the conflict in the human resources field, End-User integration, gender issues rising up during a monitoring visit and ethical aspects in field research. Through a brief comparison of both projects we summarize a range of dos and don'ts, an "acting instead of reacting" line of action, and the conclusion to a systematic overall management instead of exclusively project controlling. In a nutshell , the talk aims at providing the audience a summary of the observation in management methodologies and toolkits

    2001-09-01

    We talked about the evaluation of students' writing; this is thought to be difficult for teachers. We have a class "history of medicine" for freshmen in the second semester of the medical course. Students give lecture by themselves on famous historical persons in medicine such as Hippocrates, Vesalius, Pasteur and Sackett, referring to their historical significance in present medicine. As the final work of the subject they write report on "clinical medicine or medical researches 20 years in future and myself". We talked generally about educational evaluation in various aspects, concerning the methods for writing. We discussed mainly on two themes--ability to write and originality in thinking. We give a larger point to the originality, which correlates to ability to write, though we feel difficult in evaluating students' originality only by reading their reports. We also emphasize the importance of active interaction between students and teachers, and to evaluate educational activities of teachers in Japanese universities.

    Not-for-profit health systems are under the public microscope. Sen. Charles Grassley, (D-Iowa) chairman of the Senate Finance Committee, has been critical of the charity care and billing practices of not-for-profit health systems, and vows to introduce legislation to correct abuses throughout the tax-exempt sector. The House has studied the issue as well. Not-for-profit health systems also have been accused in hundreds of lawsuits of overcharging uninsured patients and aggressively pursuing debt collection. In this installment of Straight Talk, we explore the issues surrounding tax-exempt status and how health systems should publicize their charitable work. Modern Healthcare and PricewaterhouseCoopers present Straight Talk. The session on charity care and tax-exempt status was held on October 4, 2005 at Modern Healthcare's Chicago headquarters.

  18. Talking about others facilitates theory of mind in Chinese preschoolers.

    PubMed

    Lu, Huijing; Su, Yanjie; Wang, Qi

    2008-11-01

    A longitudinal study and a training study were conducted to show that simply referring to others facilitated theory of mind (ToM) development in Chinese children. In Study 1, 3- to 4-year-old Chinese children (N = 52) were tested on ToM and autobiographical memory (AM). One year later, in the group of children who initially failed the false belief tasks, only those who increased their references to others in AM recall passed the tasks. In Study 2, Chinese preschoolers who were trained to talk about others through storytelling showed improvement in their ToM performance. These findings suggest alternative pathways for ToM development in non-Euro-American context.

    NASA Astrophysics Data System (ADS)

    2013-10-01

    We have investigated the Ti-site substitution effect on the magnetic properties of antiferromagnetic insulator EuTiO3 with a Néel temperature of ˜5 K. Partial substitution of Ti4+ with heterovalent Al3+ or Ga3+ turns the corresponding amount of magnetic Eu2+ into non-magnetic Eu3+. Both EuTi1-xAlxO3 (0.05 ≤ x ≤ 0.10) and EuTi1-xGaxO3 (0.05 ≤ x ≤ 0.10) exhibit ferromagnetic (FM) insulating behavior below ˜4 K. The Eu2+/Eu3+ mixed valence state probably contributes to the emergence of the FM behavior. Fine control of the magneto-electric (ME) phases of EuTi1-xAlxO3 and EuTi1-xGaxO3 would lead to intriguing ME phenomena such as giant ME effect.

    Importance Physicians may be important sources of sexuality information and preventive services, and one-on-one confidential time during health maintenance visits is recommended to allow discussions of sexual development, behavior, and risk reduction. However, little is known about the occurrence and characteristics of physician-adolescent discussions about sexuality. Objective To examine predictors of time spent discussing sexuality, level of adolescent participation, and physician and patient characteristics associated with sexuality discussions during health maintenance visits by early and middle adolescents. Design, Setting, and Participants Observational study of audio-recorded conversations between 253 adolescents (mean age, 14.3 years; 53% female; 40% white; 47% African American) and 49 physicians (82% pediatricians; 84% white; 65% female; mean age, 40.9 years; mean [SD] duration in practice, 11.8 [8.7] years) coded for sexuality content at 11 clinics (3 academic and 8 community-based practices) located throughout the Raleigh/Durham, North Carolina, area. Main Outcomes and Measures Total time per visit during which sexuality issues were discussed. Results One hundred sixty-five (65%) of all visits had some sexual content within it. The average time of sexuality talk was 36 seconds (35% 0 seconds; 30% 1-35 seconds; and 35% ≥36 seconds). Ordinal logistic regression (outcome of duration: 0, 1-35, or ≥36 seconds), adjusted for clustering of patients within physicians, found that female patients (odds ratio [OR] = 2.58; 95% CI, 1.53-4.36), older patients (OR = 1.37; 95% CI, 1.13-1.65), conversations with explicit confidentiality discussions (OR = 4.33; 95% CI, 2.58-7.28), African American adolescents (OR = 1.58; 95% CI, 1.01-2.48), and longer overall visit (OR = 1.07; 95% CI, 1.03-1.11) were associated with more sexuality talk, and Asian physicians were associated with less sexuality talk (OR = 0.13; 95% CI, 0.08-0.20).

    Europium doped potassium strontium iodide is a very promising scintillator for national security applications due to its ease of growth and excellent scintillation properties. For this work the fast crystal growth and scintillation properties of 1-inch diameter single crystals of KSr2I5:Eu2+ (KSI:Eu) were investigated. We focused our efforts on optimizing the growth parameters required to produce one-inch diameter crystals without decreasing the previously reported fast pulling rate of 5 mm/h. Cracking was minimized by replacing the quartz ampoules with carbon coated quartz ampoules; thus, several crack free single crystals of KSI with varying Eu2+ concentrations were grown, including a Ø 1″ by 6″ long boule with 2.5% Eu. The maximum achievable performance of each crystal was measured using small 0.012 cm3 specimens. The volumetric dependencies of the light yield, energy resolution and decay time were evaluated using KSI:Eu 2% specimens with volumes ranging from 0.012 cm3 to 18 cm3. For large volumes (≥ 9 cm3), the performance was comparable to other high performing scintillators, with light yields up to 78,200 ph/MeV and energy resolutions as good as 3.2% at 662 keV. The initial version of a hermetic package has been developed, and the stability of the sealed crystal is promising.

    Families discuss food and eating in many ways that may shape child eating habits. Researchers studying how families talk about food have examined this process during meals. Little work has examined parent-child food-related interactions outside of mealtime. We assessed family food talk at home outside of mealtime and tested whether food talk was associated with obesogenic child eating behaviors, maternal feeding practices, or child weight. Preschool and school-aged mother-child dyads (n = 61) participated in naturalistic voice recording using a LENA (Language ENvironment Analysis) recorder. A coding scheme was developed to reliably characterize different types of food talk from LENA transcripts. Mothers completed the Children's Eating Behavior Questionnaire (CEBQ) and Child Feeding Questionnaire (CFQ) to assess child eating behaviors and maternal feeding practices. Child weight and height were measured and body mass index z-score (BMIz) calculated. Bivariate associations among food talk types, as a proportion of total speech, were examined and multivariate regression models used to test associations between food talk and child eating behaviors, maternal feeding practices, and child BMIz. Proportion of child Overall Food Talk and Food Explanations were positively associated with CEBQ Food Responsiveness and Enjoyment of Food (p's < 0.05). Child food Desire/Need and child Prep/Planning talk were positively associated with CEBQ Enjoyment of Food (p < 0.05). Child Food Enjoyment talk and mother Overt Restriction talk were positively associated with CEBQ Emotional Over-Eating (p < 0.05). Mother Monitoring talk was positively associated with CFQ Restriction (p < 0.05). Mother Prep/Planning talk was negatively associated with child BMIz. Food talk outside of mealtimes related to child obesogenic eating behaviors and feeding practices in expected ways; examining food talk outside of meals is a novel way to consider feeding practices and child eating behavior

    Hack the Planet (Wiley, 2010) explores how an idea once basically anathema to meetings like AGU has, in the space of a few years, become part of the geoscience mainstream. Through chapters involving researchers like David Battisti, Stephen Salter, Edward Teller and Brent Constanz the book documents the roots of this shift and how scientists are breaking new ground in the controversial field. And it shows how trying to engineer the planet's climate or manage its carbon poses novel scientific, geopolitical and moral risks and rewards. This session will cover how the topic of climate engineering has moved from something geoscientists don't talk about to something geoscientists can talk about, to something, in my view, that geoscientists must talk about.

  4. Cross-talk in abscisic acid signaling

    2002-01-01

    "Cross-talk" in hormone signaling reflects an organism's ability to integrate different inputs and respond appropriately, a crucial function at the heart of signaling network operation. Abscisic acid (ABA) is a plant hormone involved in bud and seed dormancy, growth regulation, leaf senescence and abscission, stomatal opening, and a variety of plant stress responses. This review summarizes what is known about ABA signaling in the control of stomatal opening and seed dormancy and provides an overview of emerging knowledge about connections between ABA, ethylene, sugar, and auxin synthesis and signaling.

    2008-03-01

    The simplicity of a liquid droplet, say a dew drop on spider silk, is both esthetically beautiful and scientifically intriguing. The interplay of surface energies, thermal motion, and confinement of the liquid, especially on small length scales can reveal interesting physics. Droplets are an ideal confining geometry because the length scales can be easily controlled and it is possible to arrange the system such that each droplet acts as an independent experiment. The talk will focus on some recent examples where we have used the droplet geometry to learn about material properties. It will become apparent in the presentation that the deviations from the ``expected'' behaviour in confined systems are far from subtle!

  9. Assessing the accuracy of self-reported self-talk

    2015-01-01

    As with most kinds of inner experience, it is difficult to assess actual self-talk frequency beyond self-reports, given the often hidden and subjective nature of the phenomenon. The Self-Talk Scale (STS; Brinthaupt et al., 2009) is a self-report measure of self-talk frequency that has been shown to possess acceptable reliability and validity. However, no research using the STS has examined the accuracy of respondents’ self-reports. In the present paper, we report a series of studies directly examining the measurement of self-talk frequency and functions using the STS. The studies examine ways to validate self-reported self-talk by (1) comparing STS responses from 6 weeks earlier to recent experiences that might precipitate self-talk, (2) using experience sampling methods to determine whether STS scores are related to recent reports of self-talk over a period of a week, and (3) comparing self-reported STS scores to those provided by a significant other who rated the target on the STS. Results showed that (1) overall self-talk scores, particularly self-critical and self-reinforcing self-talk, were significantly related to reports of context-specific self-talk; (2) high STS scorers reported talking to themselves significantly more often during recent events compared to low STS scorers, and, contrary to expectations, (3) friends reported less agreement than strangers in their self-other self-talk ratings. Implications of the results for the validity of the STS and for measuring self-talk are presented. PMID:25999887

    The Eu atoms in Pb 1-xEu xSe have long been assumed to be divalent. We show that p-type doping of this magnetic semiconductor alloy with Na can modify the effective Eu valence: a mixed, Eu 2+–Eu 3+ state appears in Pb 1-x-yEu xNa ySe at particular values of y. Magnetization, carrier concentration, resistivity, and thermopower of Pb 1-x-yEu xNa ySe are reported for a number of samples with different x and y. A pronounced increase in thermopower at a given carrier concentration was identified and attributed to the presence of enhanced ionized impurity scattering. A strong decrease in the holemore » concentration is observed in Pb1-yNaySe when Eu is added to the system, which we attribute to a Eu 2+–Eu 3+ self-ionization process. This is evidenced by magnetization measurements, which reveal a significant reduction of the magnetic moment of Pb 1-xEu xSe upon alloying with Na. Further, a deviation of magnetization from a purely paramagnetic state, described by a Brillouin function, identifies antiferromagnetic interactions between the nearest-neighbor Eu atoms: a value of J ex/k B = -0.35 K was found for the exchange coupling parameter. The conclusion of a Eu 2+–Eu 3+ self-ionization process being in effect is supported further by the electronic structure calculations, which show that an instability of the 4f 7 configuration of the Eu 2+ ion appears with Na doping. In conclusion, schematically, it was found that the Eu 4f levels form states near enough to the Fermi energy that hole doping can lower the Fermi energy and trigger a reconfiguration of a 4f electronic shell.« less

    2008-11-01

    The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

  17. What People Talk About in Virtual Worlds

    NASA Astrophysics Data System (ADS)

    Maher, Mary Lou

    This chapter examines what people talk about in virtual worlds, employing protocol analysis. Each of two scenario studies was developed to assess the impact of virtual worlds as a collaborative environment for a specific purpose: one for learning and one for designing. The first designed a place in Active Worlds for a course on Web Site Design, having group learning spaces surrounded by individual student galleries. Student text chat was analyzed through a coding scheme with four major categories: control, technology, learning, and place. The second studied expert architects in a Second Life environment called DesignWorld that combined 3D modeling and sketching tools. Video and audio recordings were coded in terms of four categories of communication content (designing, representation of the model, awareness of each other, and software features), and in terms of synthesis comparing alternative designs versus analysis of how well the proposed solution satisfies the given design task. Both studies found that people talk about their avatars, identity, and location in the virtual world. However, the discussion is chiefly about the task and not about the virtual world, implying that virtual worlds provide a viable environment for learning and designing that does not distract people from their task.

  18. Teaching About the Epistemology of Science in Upper Secondary Schools: An Analysis of Teachers' Classroom Talk

    NASA Astrophysics Data System (ADS)

    Ryder, Jim; Leach, John

    2008-02-01

    We begin by drawing upon the available literature to identify four characteristics of teacher talk likely to support student learning about the epistemology of science: making appropriate statements about the epistemology of science in the classroom, linking the epistemology of science with specific science concepts, stating and justifying learning aims, and working with students’ ideas. These characteristics are then used in an analysis of the classroom talk of seven teachers as they use published resources for teaching about the epistemology of science for the first time. By focusing on teachers’ initial classroom experiences of using these published resources we identify feasible starting points for professional development activities likely to support these teachers in developing their expertise in this challenging area of teaching. Lessons focused on a specific aspect of the epistemology of science (the development of theoretical models) contextualised within two content areas: electromagnetism and cell membrane structure. Our analysis shows that none of these teachers made clearly inappropriate statements about the epistemology of science in the classroom. However, expertise related to the remaining three characteristics of teacher talk varied between teachers. For example, some teachers used a range of approaches to working with students’ ideas during whole class talk (e.g. asking students to justify their ideas and challenging students’ views) whereas for other teachers students’ ideas were not a strong feature of classroom discourse.

    Cancer is a major cause of morbidity and mortality in the European Union (EU), and a public health burden. Improving cancer control in the EU will require implementation of efficient strategies within Member States and better policy coordination between them. In cooperation between the rotating EU Presidencies of Germany (2007), Portugal (2007) and Slovenia (2008), special attention was devoted to an integrated approach to cancer control in EU policies and programmes. A round-table focussed on national cancer plans, population-based cancer registries and cancer screening programmes was held during the Health Strategies in Europe meeting in Lisbon in July 2007, under the Portuguese Presidency. These three topics were selected as critical for improving cancer control at both national and European levels. The round-table was designed to produce a set of recommendations to inform EU cancer policy. This paper provides a résumé of the conclusions and recommendations, to stimulate wider discussion and policy development. The conclusions of the meeting were presented at the Employment, Social Policy, Health and Consumer Affairs Council in December 2007 and cancer was included in the Council Conclusions for the new European Health Strategy. Success in cancer control will require consistent attention from future EU Presidencies, such as the initiative of the Slovenian EU Presidency in early 2008.

  20. Control of Eu Luminescence Centers by Codoping of Mg and Si into Eu-Doped GaN

    The effects of Mg and Si codoping on Eu luminescence properties have been investigated in Eu-doped GaN (GaN:Eu). The Mg codoping into GaN:Eu produced novel luminescence centers consisting of Eu and Mg, and increased photoluminescence (PL) intensity in Eu,Mg-codoped GaN (GaN:Eu,Mg). However, this increased PL intensity was quenched by thermal annealing in N2 ambient, which is due to activation of Mg acceptors. In GaN:Eu,Mg codoped additionally with Si (GaN:Eu,Mg,Si), on the other hand, the Eu-Mg centers disappeared, while an additional luminescence center appeared. Furthermore, the additional luminescence center showed no quenching under N2 annealing because Si donors compensated for the Mg acceptors in GaN. Thermal quenching of the luminescence center was also approximately half of that in GaN:Eu. These results indicate that the codoping with additional impurities in GaN:Eu is a powerful technique to control Eu luminescence centers for realization of improved device performance in red light-emitting diodes using GaN:Eu.

  2. The ethics of talking about 'HIV cure'.

    PubMed

    Rennie, Stuart; Siedner, Mark; Tucker, Joseph D; Moodley, Keymanthri

    2015-03-27

    In 2008, researchers reported that Timothy Brown (the 'Berlin Patient'), a man with HIV infection and leukemia, received a stem-cell transplant that removed HIV from his body as far as can be detected. In 2013, an infant born with HIV infection received anti-retroviral treatment shortly after birth, but was then lost to the health care system for the next six months. When tested for HIV upon return, the child (the 'Mississippi Baby') had no detectable viral load despite cessation of treatment. These remarkable clinical developments have helped reinvigorate the field of 'HIV cure' research. Although this research field is largely in a pre-clinical phase, talk about curing HIV has become a regular feature in the global mass media. This paper explores the language of HIV cure from philosophical, ethical and historical perspectives. Examination of currently influential definitions of 'functional' and 'sterilizing' HIV cure reveal that these conceptualizations are more complicated than they seem. Cure is often understood in narrowly biomedical terms in isolation from the social and psychological dimensions of illness. Contemporary notions of HIV cure also inherit some of the epistemic problems traditionally associated with cures for other health conditions, such as cancer. Efforts to gain greater conceptual clarity about cure lead to the normative question of how 'HIV cure research' ought to be talked about. We argue that attention to basic concepts ethically matter in this context, and identify advantages as well as potential pitfalls of how different HIV/AIDS stakeholders may make use of the concept of cure. While concepts other than cure (such as remission) may be appropriate in clinical contexts, use of the word cure may be justified for other important purposes in the struggle against HIV/AIDS.

    With the introduction of the 6th and 7th Amendments (OJ L151, 32-37, 23 June 1993; OJ L066, 26-35, 11 March 2003) to the Cosmetic Products Directive (OJ L262, 169-200, 27 September 1976), imposing a testing and marketing ban on cosmetic products tested on animals, the retrieval of toxicological data on individual ingredients became of greater need. Since the majority of cosmetic ingredients are used for many other purposes than their cosmetic function, they fall under the scope of more than one EU Directive. An overview is given of EU legislation that could potentially affect the availability and interpretation of cosmetic safety data. It will become clear that, although cosmetics are regulated by a specific so-called "vertical" legislation, "horizontal" influences from other products' legislations play a role since they determine the type and amount of data that theoretically could be found on the specific substances they regulate. This knowledge is necessary while performing extended searches in databases and becomes indispensable when initiating negotiations with manufacturers or suppliers for obtaining the safety data required.

    Children's developing reasoning skills are better understood within the context of their social and cultural lives. As part of a research-museum partnership, this article reports a study exploring science-relevant conversations of 82 families, with children between 3 and 11 years, while visiting a children's museum exhibit about mammoth bones, and in a focused one-on-one exploration of a "mystery object." Parents' use of a variety of types of science talk predicted children's conceptual engagement in the exhibit, but interestingly, different types of parent talk predicted children's engagement depending on the order of the two activities. The findings illustrate the importance of studying children's thinking in real-world contexts and inform creation of effective real-world science experiences for children and families. © 2017 The Authors.

    The European Medicines Agency (EMA) is developing a web-based EU portal with a database "at Union level as a single entry point for the submission of data and information relating to clinical trials in accordance with" the new EU regulation No. 536/2014. The specifications are mostly published, but some documents are still missing. Because the project is integrated and has dependencies on other projects, this could result in other specification upgrades. The IT solution is under ongoing development until project completion in quarter III of 2019. The EU Portal and the database will be audited. If the audit is successful, the new regulation will come into force in October 2018. The use of the EU Portal will then be mandatory with some transition rules. The software development of the portal is restricted to the regulation and the derived requirements. It is not possible to implement any national requirements. We describe in this paper the current key functionalities of the portal and try to derive requirements for a national IT system.On 16.06.2017 the EMA Management Board announced that the development of the new portal has been delayed and it is foreseen that the new regulation can come into effect in 2019 at the earliest. The press release can be found here: http://www.ema.europa.eu/ema/index.jsp?curl=pages/news_and_events/news/2017/06/news_detail_002764.jsp%26mid=WC0b01ac058004d5c1 (accessed: 12.07.2017).

    The European Clinical Database EuCliD small star, filled has been developed as a tool for supervising selected quality indicators of about 200 European dialysis centers. Major efforts had to be made to comply with local and European laws regarding data security. EuCliD is a Lotus Notes based flat-file database currently containing medical data of more than 14,000 dialysis patients from 10 European countries. Another 15,000 patients from 150 centers in 4 South-American countries will be added soon. Data are entered either manually or by means of interfaces to existing local data managing systems. This information is transferred to a central Lotus Notes Server. Data evaluation was performed with statistical tools like SPSS. EuCliD is used as a part of the CQI (Continuous Quality Improvement) management system of Fresenius Medical Care (FMC) dialysis units. Each participating dialysis center receives (currently every half year) benchmarking reports at a regular interval. The benchmark for all quality parameters is the weighted mean of the corresponding data of all centers. An obvious impact of data sampling and data evaluation on the quality of the treatments could be observed within the first one and a half years of working with EuCliD. This also concerns important outcome predictors like Kt/V and hemoglobin concentration as the outcome itself expressed in hospitalization days and survival rates. With the help of EuCliD the user is able to sample clinical data, identify problems, search for solutions with the aim of improving the dialysis treatment quality and guarantee a high-class treatment quality for all patients.

  14. Brief, embedded, spontaneous metacognitive talk indicates thinking like a physicist

    NASA Astrophysics Data System (ADS)

    Sayre, Eleanor C.; Irving, Paul W.

    2015-12-01

    [This paper is part of the Focused Collection on Upper Division Physics Courses.] Instructors and researchers think "thinking like a physicist" is important for students' professional development. However, precise definitions and observational markers remain elusive. We reinterpret popular beliefs inventories in physics to indicate what physicists think thinking like a physicist entails. Through discourse analysis of upper-division students' speech in natural settings, we show that students may appropriate or resist these elements. We identify a new element in the physicist speech genre: brief, embedded, spontaneous metacognitive talk (BESM talk). BESM talk communicates students' in-the-moment enacted expectations about physics as a technical field and a cultural endeavor. Students use BESM talk to position themselves as physicists or nonphysicists. Students also use BESM talk to communicate their expectations in four ways: understanding, confusion, spotting inconsistencies, and generalized expectations.

  15. Luminescence variations in hydroxyapatites doped with Eu2+ and Eu3+ ions.

    PubMed

    Graeve, Olivia A; Kanakala, Raghunath; Madadi, Abhiram; Williams, Brandon C; Glass, Katelyn C

    2010-05-01

    We present a detailed analysis of the luminescence behavior of europium-doped hydroxyapatite (HAp) and calcium-deficient hydroxyapatite (Ca-D HAp) nanopowders. The results show that, while both powders are similar in crystallite size, particle size, and morphology, the luminescence behavior differs significantly. For the HAp:Eu powders, the emission is clearly from Eu(3+) ions and corresponds to typical (5)D(0) --> (7)F(J) emissions, whereas for the Ca-D HAp:Eu powders, we also see a broad emission with two peaks at 420 and 445 nm, corresponding to the 4f(6)5d(1) --> 4f(7) ((8)S(7/2)) transition of Eu(2+). The powders are weakly luminescent in the as-synthesized state, as expected for combustion-synthesized materials and have higher emission intensities as the heat treatment temperature is increased. Luminescence spectra obtained using an excitation wavelength of 254 nm are weak for all samples. Excitation wavelengths of 305, 337, and 359 nm, are better at promoting the Eu(3+) and Eu(2+) emissions in hydroxyapatites. We propose that fluorescence measurements are an excellent way of qualitatively determining the phase composition of europium-doped hydroxyapatite powders, since powders that exhibit a blue emission contain substantial amounts of Ca-D HAp, allowing the determination of the presence of this phase in mixed-phase hydroxyapatites.

    2017-04-01

    A major challenge for healthcare quality improvement is the lack of IT skills and knowledge of healthcare workforce, as well as their ambivalent attitudes toward IT. This article identifies and prioritizes actions needed to improve the IT skills of healthcare workforce across the EU. A total of 46 experts, representing different fields of expertise in healthcare and geolocations, systematically listed and scored actions that would improve IT skills among healthcare workforce. The Child Health and Nutrition Research Initiative methodology was used for research priority-setting. The participants evaluated the actions using the following criteria: feasibility, effectiveness, deliverability, and maximum impact on IT skills improvement. The leading priority actions were related to appropriate training, integrating eHealth in curricula, involving healthcare workforce in the eHealth solution development, improving awareness of eHealth, and learning arrangement. As the different professionals' needs are prioritized, healthcare workforce should be actively and continuously included in the development of eHealth solutions.

  20. Invited Talks at Naples and Coimbra

    NASA Technical Reports Server (NTRS)

    Jordan, Stuart

    2003-01-01

    Prior to observations of the solar irradiance from space that began in 1979 there was no hope of obtaining even rough estimates of the solar irradiance variation over a solar cycle, since the space observations made since showed that the magnitude of the variation over a cycle to date is less than 0.1 %, a value too small to measure from the ground. At the same time, it would be useful to know the cycle-dependent variation over more than just the two recent cycles. Lacking a complete theory for the solar dynamo responsible for this variation, the current hope is to determine what proxy might yield the best values. Because there is an excellent database on sunspot umbral and penumbral areas from the Greenwich Observatory for the years 1874-1976 (but not beyond), the possibility exists that these data could be used. This talk will summarize results of a joint study in which satellite measurements of the solar irradiance variation are compared with ground-based measurements from the Coimbra Observatory of sunspot number, umbral area, and total sunspot area to determine which would serve as the best proxy for using the Greenwich observations back to 1874. From the near constancy of sunspot umbral magnetic fields upon which the useful parameter photometric sunspot index is based, we expected that umbral area would yield the beat proxy. To our surprise, after performing a statistical study of the observations over the period 1980-1990, preliminary indications are that sunspot number (a parameter available back into the 18th century) may be just as useful as the umbral area. As expected, both are quite superior as proxies to total sunspot area, which includes the penumbral area. This conclusion is consistent with earlier work of Hop and Schatten, who sought a proxy by studies of the umbral-penumbral area ratio. A second motivation for pursuing this work is the possibility that relatively small variations in the solar irradiance may induce larger responses in Earth

    2017-10-01

    The scaling and similarity technique is a powerful tool for developing and testing reduced models of complex phenomena, including plasma phenomena. The technique has been successfully used in identifying appropriate simplified models of transport in quasistationary plasmas. In this talk, the similarity and scaling arguments will be applied to highly dynamical systems, in which temporal evolution of the plasma leads to a significant change of plasma dimensions, shapes, densities, and other parameters with respect to initial state. The scaling and similarity techniques for dynamical plasma systems will be presented as a set of case studies of problems from various domains of the plasma physics, beginning with collisonless plasmas, through intermediate collisionalities, to highly collisional plasmas describable by the single-fluid MHD. Basic concepts of the similarity theory will be introduced along the way. Among the results discussed are: self-similarity of Langmuir turbulence driven by a hot electron cloud expanding into a cold background plasma; generation of particle beams in disrupting pinches; interference between collisionless and collisional phenomena in the shock physics; similarity for liner-imploded plasmas; MHD similarities with an emphasis on the effect of small-scale (turbulent) structures on global dynamics. Relations between astrophysical phenomena and scaled laboratory experiments will be discussed.

    Accelerator science and technology is one of a key enablers of the developments in the particle physic, photon physics and also applications in medicine and industry. EuCARD2 is an European research project which will be realized during 2013-2017 inside the EC FP7 framework. The project concerns the development and coordination of European Accelerator Research and Development. The project is particularly important, to a number of domestic laboratories, due to some plans to build large accelerator infrastructure in Poland. Large accelerator infrastructure of fundamental and applied research character stimulates around it the development and industrial applications as well as biomedical of advanced accelerators, material research and engineering, cryo-technology, mechatronics, robotics, and in particular electronics - like networked measurement and control systems, sensors, computer systems, automation and control systems. The paper presents a digest of the European project EuCARD2 which is Enhanced European Coordination for Accelerator Research and Development. The paper presents a digest of the research results and assumptions in the domain of accelerator science and technology in Europe, shown during the final fourth annual meeting of the EuCARD - European Coordination of Accelerator R&D, and the kick-off meeting of the EuCARD2. There are debated a few basic groups of accelerator systems components like: measurement - control networks of large geometrical extent, multichannel systems for large amounts of metrological data acquisition, precision photonic networks of reference time, frequency and phase distribution, high field magnets, superconducting cavities, novel beam collimators, etc. The paper bases on the following materials: Internet and Intranet documents combined with EuCARD2, Description of Work FP7 EuCARD-2 DoW-312453, 2013-02-13, and discussions and preparatory materials worked on by Eucard-2 initiators.

  3. Synthesis, characterization, and luminescent properties of Eu3+ dipyridophenazine functionalized complexes for potential bioimaging applications

    NASA Astrophysics Data System (ADS)

    Beasley, Jeremy

    Luminescent properties of lanthanide complexes possess unique characteristics that make them good candidates for possible bioimaging agents and have inspired research initiatives to further explore these materials. However, the toxicity of these metals limits their applications as in-vivo bioimaging agents. One solution that eliminates the toxic effects is to encase these lanthanide complexes in silica. This project was designed to probe the variation in the fluorescence properties of a highly luminescent europium (III) complex, utilizing a fluorinated â-diketonate ligand (thenoyltrifluoroacetone (tta)), upon the substitution of the solvent molecules by various functionalized dipyrido[3,2-a:2',3'-c]phenazine (DPPZ) ligands. A method for covalently attaching, or occluding complexes in silica nanoparticles were also included in the project design. The structure and properties of the functionalized DPPZ ligands and their respective complexes were determined by FT-IR, 1H-NMR, UV-Vis, and fluorescence spectroscopy techniques. UV excitation of the complexes resulted in red luminescence (~ 614 nm) characteristic of trivalent europium ions. The differences in luminescence properties of the complexes are rationalized in terms of the electronic features of the different functionalized DPPZ ligands. The higher overall quantum yield of the un-functionalized DPPZ complex, Eu(tta)3DPPZ (Q.Y.= 7.68 +/- 0.06 %), and the low overall quantum yield observed for Eu(tta)3DPPZ-COOEt (Q.Y.= 1.08 +/- 0.05%), Eu(tta) 3DPPZ-Si (Q.Y.= 0.65+/- 0.04%), Eu(tta)3DPPZ-COOH (Q.Y.= 0.61+/- 0.07 %), Eu(tta)3DPPZ-CH3 (Q.Y.= 0.59+/-0.02 %) are rationalized in terms of how electron donating or withdrawing groups affect their respective ligand-to-metal energy transfer efficiencies. Eu(tta) 3DPPZ was the only complex to show enhanced luminescent properties capable of potential applications in biomedical imaging.

    Although "fat talk" is associated with increased eating disorder risk, the predictors of fat talk engagement and viable alternatives to these pervasive conversations remain unclear. The current experiment examined responses to fat talk versus feminist-oriented challenging fat talk scenarios. Undergraduate women (N=283) completed baseline questionnaires assessing body dissatisfaction, fat talk engagement, and positive impression management. One week later, they were randomized to view one of the two scenarios, followed by assessment of mood, fat talk engagement, social acceptability, and social likeability. Results indicated that the challenging fat talk vignette (versus the fat talk vignette) yielded less negative affect and fat talk and was perceived as more socially attractive with a more likeable target character. Baseline body dissatisfaction, baseline fat talk tendencies, and momentary negative affect predicted post-exposure fat talk engagement. Current findings highlight possibilities for implementing feminist language and psychoeducation in fat talk prevention efforts. Copyright © 2017 Elsevier Ltd. All rights reserved.

  5. Methods work better when couples talk.

    Sexual partners who communicate about reproductive health issues reduce their risk of acquiring a sexually transmitted disease (STD) or of unintended pregnancy, but few couples feel comfortable talking openly about sex. AIDS prevention programs have focused on improving couple communication, but family planning programs have emphasized women-controlled contraception as more reliable than barrier methods. The effectiveness of barrier methods would likely improve, however, if clients are counseled in couple communication. Effective communication about sexual issues requires self-confidence, and strengthening a woman's self-confidence may also improve her ability to negotiate condom use. Small discussion groups held among female factory workers in Thailand in 1993-94 led to an increase from 60% to 90% in the number of women who felt confident in discussing STD risk with a partner and to an increase from 36% to 82% in those who said they would not be embarrassed to give a partner a condom. A Nigerian study also suggested that more education may also improve prospects for couple communication and contraceptive usage. A US study showed that adolescent women who communicated openly with their partners reduced their risks of unintended pregnancy and STDs, and a Kenyan study indicated that communication increases contraceptive usage among married couples. Various projects around the world are attempting to counsel women on communication and condom negotiation, and counselors are beginning the difficult task of teaching women how to convince men to use condoms.

    Aboard the International Space Station (ISS), Cosmonaut and Expedition Three flight engineer Vladimir N. Dezhurov, representing Rosaviakosmos, talks with flight controllers from the Zvezda Service Module. Russian-built Zvezda is linked to the Functional Cargo Block (FGB), or Zarya, the first component of the ISS. Zarya was launched on a Russian Proton rocket prior to the launch of Unity. The third component of the ISS, Zvezda (Russian word for star), the primary Russian contribution to the ISS, was launched by a three-stage Proton rocket on July 12, 2000. Zvezda serves as the cornerstone for early human habitation of the Station, providing living quarters, a life support system, electrical power distribution, a data processing system, flight control system, and propulsion system. It also provides a communications system that includes remote command capabilities from ground flight controllers. The 42,000-pound module measures 43 feet in length and has a wing span of 98 feet. Similar in layout to the core module of Russia's Mir space station, it contains 3 pressurized compartments and 13 windows that allow ultimate viewing of Earth and space.

    Addressing race and racial trauma within psychotherapy supervision is increasingly important in psychiatry training. A therapist's ability to discuss race and racial trauma in psychotherapy supervision increases the likelihood that these topics will be explored as they arise in the therapeutic setting. The authors discuss the contextual and sociocultural dynamics that contributed to their own avoidance of race and racial trauma within the supervisory relationship. The authors examine the features that eventually led to a robust discussion of race and culture within the supervisory setting and identify salient themes that occurred during three phases of the conversation about race: pre-dialogue, the conversation, and after the conversation. These themes include building an alliance, supercompetence, avoidance, shared vulnerability, "if I speak on this, I own it," closeness versus distance, and speaking up. This article reviews the key literature in the field of psychiatry and psychology that has shaped how we understand race and racial trauma and concludes with guidelines for supervisors on how to facilitate talking about race in supervision.

EuCu 5In and EuAg 5In order antiferromagnetically at T N = 12 and 6 K, respectively, whereas EuAu 5In is ferromagnetic below T C = 13 K. EuCu 5In exhibits complex magnetism: after the initial drop at T N, the magnetization rises again below 8 K, and a weak metamagnetic-like transition occurs at 2 K in μ 0H = 1.8 T. The electronic heat capacity of EuCu 5In, γ = ~400 mJ/(mol K 2), points to strong electronic correlations. Spin-polarized densities of states suggest that the magnetic interactions in the three materials studied are supported via mixing 4 f and 5 d states of Eu. As a result, a chemical bonding analysis based on the Crystal Orbital Hamilton populations reveals the tendency to maximize overall bonding as a driving force to adopt a particular type of crystal structure.« less

    Founded in 2008 by leading scientists and communications experts at Princeton, Yale and Stanford, Climate Central brings together award-winning journalists and internationally recognized scientists to report the science and impacts of climate change through its research and journalism programs. Climate Central works to tackle the misperception that climate change is a distant thing - affecting other people and other places - by demonstrating the local and personal impacts of global warming. This talk will focus on describing three important Climate Central initiatives. First, our Climate Matters program delivers localized climate information at the regional and local level to weathercasters around the U.S., providing ready-to-use, broadcast quality graphics and analyses that put climate change in a local context. After three years, the program has grown from a pilot with just one TV meteorologist in Columbia, South Carolina to a network of more than 150 weathercasters across the country. Climate Central was also closely involved in the development and production of Years of Living Dangerously - a 9-part global warming documentary that premiered in April 2014. Finally, the World Weather Attribution project is a new initiative that aims to identify the human fingerprint in certain types of extreme weather events, including sea level rise and its contribution to storm surges, extreme heat events, heavy rainfall events/flooding, and drought. Our goal is to objectively and transparently assess certain extreme events and equip journalists and scientists with the tools to provide the larger global warming context in real-time while there is still media interest.

    The European Council of Ministers has postponed discussion of the European Commission`s proposed energy tax and has authorized a study to reevaluate the technical and legal implications and the costs and benefits of the tax. The reevaluation comes as a ray of hope to European chemical industry officials, who are concerned about the effects of the tax on the industry`s international competitiveness. The commission`s proposal would tax natural gas, electricity, and coal in the European Union (EU) for the first time. It would raise taxes throughout the EU to one level. In its current form the energy tax would devastatemore » the European industry`s competitiveness outside the region, says European Chemical Industry Council (Cefic) counsel Claude Culem. We`re willing to improve emissions to achieve environmental goals - we don`t need energy taxes, Culem tells CW. The whole project is dangerous, not necessarily in the short term, but certainly in the long term. European Parliament ministers are scheduled to debate the issue with the Dutch government, which holds the EU presidency, and hope to wrap up proceedings over the summer. The tax may only be adopted when ministers agree on it unanimously. If it is approved, it would be implemented in two stages, in 2000 and 2002.« less

    The study presents the results of a case study with a repeated data collection design: a recent and former world champion power lifter provided weekly e-mails, during approximately 6 mo. of training and competition, with a description of his 'self-determined self-talk.' The instruction used for self-talk (ST) mentioned its associations with emotions, staying focused, maintaining motivation, and improving exercise skills. The obtained e-mails were coded using categories indicating functions of 'self-determined self-talk' mainly based on previous literature. The frequency of the functions during training and competition were compared and discussed following the qualitative research tradition.

    The effects of pH, initial Eu(III) concentration, ionic strength and fulvic acid (FA) on the adsorption of Eu(III) on TiO(2) are investigated by using batch techniques. The results indicate that the presence of FA strongly enhances the adsorption of Eu(III) on TiO(2) at low pH values. Besides, the adsorption of Eu(III) on TiO(2) is significantly dependent on pH values and independent of ionic strength. The adsorption of Eu(III) on TiO(2) is attributed to inner-sphere surface complexation. The diffuse layer model (DLM) is applied to simulate the adsorption data, and fits the experimental data well with the aid of FITEQL 3.2. X-ray photoelectron spectroscopy (XPS) is performed to study the species of Eu(III) adsorbed on the surfaces of TiO(2)/FA-TiO(2) hybrids at a molecular level, which suggest that FA act as "bridge" between Eu(III) and TiO(2) particles to enhance the ability to adsorb Eu(III) in solution.

    It is widely recognized that productivity gains, sustained economic growth and employment are largely determined by technological progress, innovation and human capital. The 2000 Lisbon strategy to make Europe a competitive knowledge-based economy by 2010 and, more specifically, the Barcelona objectives agreed upon in 2002 to increase R&D investment in the EU to approach 3% of GDP, ensuring that there are sufficient human resources for research, are a preliminary step in this direction. If we want to reach this goal we have to succeed in retaining the best researchers, creating the right environment where they can perform their activities and develop their careers. To this aim the Organization of European Cancer Institutes (OECI) has set up a working group on Education and Training with the mandate to encourage continuing education in cancer research and applications and to verify the feasibility to promote mobility programs inside the network and in association with industries. Until now only few OECI training programs have been launched and a full mobility program has not been developed yet due to limited budget resources. The Italian Network of Comprehensive Cancer Centers, Alleanza Contro il Cancro, has planned the launch of a mobility program awarding 70 annual fellowships over a period of 36 months. This program, which will be open to the world research community, could represent a first interaction through mobility among the members of the OECI network also involving industries. The program is a tangible approach to sustain the translational process needed for the development of an European Research Area in the field of cancer and its related biomedical disciplines, thus providing a practical answer to the 2005 renewed Lisbon Strategy.

    This article explores the meanings of substance-abusing clients attach to friendships during motivational treatment sessions in Probation Service. Sessions (98) were videotaped in 12 probation service offices in Finland in 2007 to 2009. By using semiotic framework, this qualitative study examines client's change talk utterance about friendships as a symbolic sign. The findings indicate that the friendships play an important role in the substance-abusing clients' motivation to change and in their treatment outcome. The study suggests that the personal meanings of clients' utterances in motivational treatment sessions could be seen as potential predictors of their future behavior.

    Background The problem of antimicrobial resistance requires common strategies at the European level. Methods We report on an EU initiative fostering antibiotic (AB) stewardship (ABS) in hospitals. Results The project ‘ABS International: implementing antibiotic strategies for appropriate use of antibiotics in hospitals in member states of the EU’ started in September 2006 in Austria, Belgium, the Czech Republic, Germany, Hungary, Italy, Poland, Slovenia and Slovakia. A training program for national ABS trainers was prepared and standard templates for ABS tools (AB list, guidelines for AB treatment and surgical prophylaxis, and AB-related organization) and valid process measures as well as quality indicators for AB use were developed. Specific ABS tools are being implemented in up to five health care facilities per country. Conclusion ABS International is the first EU-funded initiative focusing on the implementation of structural measures in hospitals to promote the prudent use of ABs. PMID:18667815

    This study firstly shows with in situ hybridization on human pancreas that TALK-1 and TALK-2, two members of the 2P domain potassium channel (K2P) family, are highly and specifically expressed in the exocrine pancreas and absent in Langherans islets. On the contrary, expression of TASK-2 in mouse pancreas is found both in the exocrine pancreas and in the Langherans islets. This study also shows that TALK-1 and TALK-2 channels, expressed in Xenopus oocytes, are strongly and specifically activated by nitric oxide (obtained with a mixture of sodium nitroprussate (SNP) and dithiothreitol (DTT)), superoxide anion (obtained with xanthine and xanthine oxidase) and singlet oxygen (obtained upon photoactivation of rose bengal, and with chloramine T). Other nitric oxide and reactive oxygen species (NOS and ROS) donors, as well as reducing conditions were found to be ineffective on TALK-1, TALK-2 and TASK-2 (sin-1, angeli's salt, SNP alone, tBHP, H2O2, and DTT). These results suggest that, in the exocrine pancreas, specific members of the NOS and ROS families could act as endogenous modulators of TALK channels with a role in normal secretion as well as in disease states such as acute pancreatitis and apoptosis.

    A secure supply of raw materials is a European priority that extends beyond country borders and national policies. Recent European initiatives have pioneered the development of an EU strategy on raw materials emphasizing the concept of the "added value chain", which continues to pursue the three pillar strategy to: (1) ensure the fair and sustainable supply of raw materials from international markets, promoting international cooperation with developed and developing countries; (2) foster sustainable supply of raw materials from European sources, and (3) reduce consumption of primary raw materials by increasing resource efficiency and promoting recycling. This contribution presents the Horizon 2020 funded project INTRAW, the objective of which is to establish the European Union's International Observatory for Raw Materials. The creation and maintenance of the European Union's International Observatory for Raw Materials is designed to have a strong impact in two dimensions: 1. To narrow the existing gap in aspects of the raw materials knowledge infrastructure in the EU by providing a link with the same knowledge infrastructure in technologically advanced reference countries. This should contribute to the harmonization of mineral policies all over the EU, by providing data that enables evidence-based policies and appropriate, cost-effective management, planning and adaptation decisions by the public sector. This will benefit businesses, industry and society. The Observatory will also provide to policy makers in the EU and its Member States the data they need to facilitate discussion in multilateral forums. 2. To enable a better alignment of the R&I activities among the individual EU members and international cooperation countries AND between the European Union and international cooperation countries by boosting synergies with international research and innovation programmes. This way the EU's role and scientific capabilities in the raw materials area will be

    Ni/EuS multilayers with excellent multilayer sequencing are deposited via e-beam evaporation on the native oxide of Si(100) wafers at 4 × 10{sup −9} millibars. The samples have very small surface and interface roughness and show sharp interfaces. Ni layers are nanocrystalline 4–8 nm thick and EuS layers are 2–4 nm thick and are either amorphous or nanocrystalline. Unlike for Co/EuS multilayers, all Eu ions are in divalent (ferromagnetic) state. We show a direct antiferromagnetic coupling between EuS and Ni layers. At room temperature, the EuS layers are spin-polarized due to the proximity of Ni. Therefore, Ni/EuS is a candidate for room-temperature spintronics applications.

  20. Identifying and Supporting Productive Collaborative Teacher Talk

    Flarend, Alice M.

    As improvements and changes in science education are promulgated, science teachers must be educated about these changes. Professional development programs are central to promoting teacher learning. Although the field seems to have agreed upon large-scalepedagogical features of high quality professional development with an emphasis on building a collaborative community of learners, effective implementation of these features is still problematic. The connections between these collaborative features and actual teacher work during the professional development remain unclear. This qualitative discourse study investigated how teachers engaged in small group discussions use discourse to collaborate during a weeklong professional development program that employed these useful pedagogical features. Small group discussions among the forty-two participants, diverse in their demographics and teaching experiences, were video and audio recorded. A collaborative discourse framework is developed and applied to the discussions, successfully categorizing episodes of discourse according to their productive potential for learning. The structure of the PD activities is then investigated to determine characteristics encouraging to these productive learning conversations. The analysis in this study indicated requiring groups to come to a consensus helps groups dig deeper into the content, promoting a more productive negotiation of concepts. Building consensus around an artifact such as a graph strengthened the need for consensus and thereby strengthened the opportunities for productive conversation. In addition, professional development activities that target building and using specific language were also opportunities for productive learning talk, providing opportunities to negotiate the deep meaning of words and concepts rather then leaving them unexamined. When viewed through the lens of Wenger's Community of Practice (1998) these findings are ways of strengthening the community

    Eu-Ga-O ternary compounds were synthesized from a mixture of cubic (c-) Eu2O3 and monoclinic Ga2O3 (β-Ga2O3) raw powders using the solid-state reaction method by calcination at Tc = 1200 °C. The structural and optical properties of the Eu-Ga-O ternary compounds were investigated using X-ray diffraction analysis, photoluminescence (PL) analysis, PL excitation (PLE) spectroscopy, and Raman scattering measurements. Stoichiometric compounds such as cubic Eu3Ga5O12 (EGG) and orthorhombic Eu3GaO6 were synthesized using molar ratios of x = 0.375 and 0.75 [x≡Eu2O3/(Eu2O3 + Ga2O3)], respectively, together with the end-point binary compounds β-Ga2O3 (x = 0) and monoclinic (m-) Eu2O3 (x = 1.0). The structural change from "cubic" to "monoclinic" in Eu2O3 is due to the structural phase transition occurring at Tc ≥ 1050 °C. In principle, the perovskite-type EuGaO3 and monoclinic Eu4Ga2O9 can also be synthesized at x = 0.5 and 0.667, respectively; however, such stoichiometric compounds could not be synthesized in this study. The PL and PLE properties of EGG and Eu3GaO6 were studied in detail. The temperature dependence of the PL spectra was observed through measurements carried out between T = 20 and 300 K and explained using a newly developed model. Raman scattering measurements were also performed on the Eu-Ga-O ternary systems over the entire composition range from x = 0 (β-Ga2O3) to 1.0 (m-Eu2O3).

    Ligand L, based on two do3a moieties linked by the methylene groups of 6,6'-dimethyl-2,2'-bipyridine, was synthesized and characterized. The addition of Ln salts to an aqueous solution of L (0.01 M Tris-HCl, pH 7.4) led to the successive formation of [LnL] and [Ln(2)L] complexes, as evidenced by UV/Vis and fluorescence titration experiments. Homodinuclear [Ln(2)L] complexes (Ln = Eu, Gd, Tb, Yb, and Lu) were prepared and characterized. The (1)H and (13)C NMR spectra of the Lu and Yb complexes in D(2)O solution (pD = 7.0) showed C(1) symmetry of these species in solution, pointing to two different chemical environments for the two lanthanide cations. The analysis of the chemical shifts of the Yb complex indicated that the two coordination sites present square antiprismatic (SAP) coordination environments around the metal ions. The spectroscopic properties of the [Tb(2)L] complex upon ligand excitation revealed conventional behavior with τ(H2O) = 2.05(1) ms and ϕ(H2O) = 51%, except for the calculation of the hydration number obtained from the luminescent lifetimes in H(2)O and D(2)O, which pointed to a non-integer value of 0.6 water molecules per Tb(III) ion. In contrast, the Eu complex revealed surprising features such as: 1) the presence of two and up to five components in the (5)D(0)→(7)F(0) and (5)D(0)→(7)F(1) emission bands, respectively; 2) marked differences between the normalized spectra obtained in H(2)O and D(2)O solutions; and 3) unconventional temporal evolution of the luminescence intensity at certain wavelengths, the intensity profile first displaying a rising step before the occurrence of the expected decay. Additional spectroscopic experiments performed on [Gd(2-x)Eu(x)L] complexes (x = 0.1 and 1.9) confirmed the presence of two distinct Eu sites with hydration numbers of 0 (site I) and 2 (site II), and showed that the unconventional temporal evolution of the emission intensity is the result of an unprecedented intramolecular Eu-to-Eu

    We present a 28-year-old female patient whose epilepsy started at the age of 19. MRI showed right perisylvian polymicrogyria. She exhibited various seizure symptoms, such as somatosensory aura involving the left leg, dyscognitive seizures, and amnesic seizures. Her mother indicated that the patient sometimes had "sleep talking", which was associated with presence of epileptic seizures of the next day. Long-term video electroencephalography (EEG) revealed that her episodes of "sleep talking" were epileptic events, specifically ictal speech, originating in the right hemisphere. The present case demonstrates the importance of considering "sleep talk" as an epileptic symptom. Careful history taking is fundamental to carry patients with possibly pathological "sleep talk" to the long-term video EEG, which will contribute correct diagnosis and treatment.

    Experimental mesocosms are valuable tools to fill the gap between highly controlled/replicated lab experiments and uncontrolled/non-replicated natural environments such as rivers, lakes and oceans. WWW.MESOCOSM.EU is an open web-portal for leading aquatic mesocosm facilities around the world. It was created within the FP7 EU-project MESOAQUA (A network of leading MESOcosm facilities to advance the studies of future AQUAtic ecosystems from the Arctic to the Mediterranean). The goal of the portal is to increase international knowledge about existing mesocosm facilities, including information on locations, environment, equipment, contacts, research opportunities and mesocosm-based publications. MESOCOSM.EU specifically aims to be a tool to enhance the quality of research by facilitating international cooperative network building, announcement of new research initiatives, transfer of best practice, and dissemination of knowledge, public information and press releases. As an open platform for all aquatic ecosystem scale science (marine and freshwater), MESOCOSM.EU aims to fill the lack of a centralized, coordinating virtual infrastructure for international aquatic mesocosm research, from the mountains to the ocean and from polar to tropical regions.

    Undoped and europium (III)-doped ZnO nanoparticles were prepared by a sonochemical method. The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) analysis. The crystalline sizes of undoped and 3% Eu-doped ZnO were found to be 16.04 and 8.22nm, respectively. The particle size of Eu-doped ZnO nanoparticles was much smaller than that of pure ZnO. The synthesized nanocatalysts were used for the sonocatalytic degradation of Acid Red 17. Among the Eu-doped ZnO catalysts, 3% Eu-doped ZnO nanoparticles showed the highest sonocatalytic activity. The effects of various parameters such as catalyst loading, initial dye concentration, pH, ultrasonic power, the effect of oxidizing agents, and the presence of anions were investigated. The produced intermediates of the sonocatalytic process were monitored by GC-Mass (GC-MS) spectrometry. Copyright © 2015 Elsevier B.V. All rights reserved.

    Optically stimulated luminescence (OSL) and thermoluminescence are observed in polycrystalline RbMgF3:Eu2+ after x-ray, γ-ray, or β irradiation. The main electron traps are F-centers but there are other unidentified traps. The main hole traps at room temperature are probably Eu3+ and thermal or optical stimulation leads to electron-hole recombination at the Eu3+ site and Eu2+ emissions arising from P6J to S87/2 and 4f5d(Eg) to S87/2 transitions. We find that some of the electron traps can be emptied by infrared stimulation and all of the electron traps can be emptied by white light stimulation. The OSL dark decay is long and exceeds 5 days for traps that are emptied by white light stimulation after initial infrared bleaching. Our results show that this compound can be used as a radiation dosimeter for intermediate dose levels where the R87b self-dose does not significantly affect the dose reading.

    The integrated European project, EU-ToxRisk, proudly sees itself as "flagship" exploring new alternative-to-animal approaches to chemical safety evaluation. It promotes mechanism-based toxicity testing and risk assessment according to the principles laid down for toxicology for the twenty-first century. The project was officially launched in January 2016 with a kickoff meeting in Egmond aan Zee, the Netherlands. Over 100 scientists representing academia and industry as well as regulatory authorities attended the inaugural meeting. The project will integrate advances in in vitro and in silico toxicology, read-across methods, and adverse outcome pathways. EU-ToxRisk will continue to make use of the case study strategy deployed in SEURAT-1, a FP7 initiative ended in December 2015. Even though the development of new non-animal methods is one target of EU-ToxRisk, the project puts special emphasis on their acceptance and implementation in regulatory contexts. This €30 million Horizon 2020 project involves 38 European partners and one from the USA. EU-ToxRisk aims at the "development of a new way of risk assessment."

  13. Cross-Talk Limits of Highly Segmented Semiconductor Detectors

    2011-06-01

    Cross-talk limits of monolithic highly-segmented semiconductor detectors for high-resolution X-gamma spectrometry are investigated. Cross-talk causes false signal components yielding amplitude losses and fold-dependent shifts of the spectral lines, which partially spoil the spectroscopic performance of the detector. Two complementary electrical models are developed, which describe quantitatively the inter-channel cross-talk of monolithic segmented detectors whose electrodes are read out by charge-sensitive preamplifiers. The first is here designated as Cross-Capacitance (CC) model, the second as Split-Charge (SC) model. The CC model builds around the parasitic capacitances Cij linking the preamplifier outputs and the neighbor channel inputs. The SC model builds around the finite-value of the decoupling capacitance CC used to read out the high-voltage detector electrode. The key parameters of the models are individuated and ideas are shown to minimize their impact. Using a quasi-coaxial germanium segmented detector it is found that the SC cross-talk becomes negligible for decoupling capacitances larger than 1 nF, where instead the CC cross-talk tends to dominate. The residual cross-talk may be reduced by minimization of stray capacitances Cij, through a careful design of the layout of the Printed Circuit Board (PCB) where the input transistors are mounted. Cij can be made as low as 5 fF, but it is shown that even in such case the impact of the CC cross-talk on the detector performance is not negligible. Finally, an algorithm for cross-talk correction is presented and elaborated.

    Bixbyite type Y2O3:Eu3+ apart from being the efficient red phosphor extensively used in trichromatic fluorescent lamps, it is a typical system one can apply Jørgensen's refined electron spin pairing theory. This can be used to explain the enhancement in Eu3+ emission intensity observed with the aliovalent substitution in the yttria host matrix. Results based on these are explained qualitatively by considering a simple configurational coordinate model. Futhermore, an insight into the different types of defects induced with the aliovalent substitution in the yttria lattice has become possible with EPR probe.

    Fat talk, negative communication about weight, is common in the media, peer groups, and families. Little is known about parental fat talk directed at oneself or others. This study examined associations between different forms of parental fat talk and child disordered eating behaviors and weight, and differences by child sex and age. Parents of preadolescents or adolescents (n = 581) reported fat talk about themselves (self-fat talk), others (obesity-fat talk), and their child (child-fat talk). 76.0% of parents reported regular self-fat talk in front of children, 51.5% reported obesity-fat talk, and 43.6% reported child-fat talk. Fat talk did not differ significantly between parents of preadolescents and adolescents but was more common with sons than daughters. Of the three forms of fat talk, only child-fat talk was associated with all child eating and weight variables (binge eating, overeating, secretive eating, and overweight/obesity); associations were strongest for adolescent girls. Child sex was associated with secretive eating and overweight/obesity. Parents reported using different forms of fat talk frequently. Parent self- and obesity-fat talk were reported more frequently, but child-fat talk was the most strongly associated with children's eating and weight. Because of associations with disordered eating behaviors, intervening to reduce fat talk might contribute to improving pediatric disordered eating and weight-related interventions. © 2018 Wiley Periodicals, Inc.

    Resonant photoemission spectroscopy, with application of synchrotron radiation, was used to study the valence band electronic structure of clean surface of (EuGd)Te layers. Fano-type resonant photoemission spectra corresponding to the Eu 4d-4f transition were measured to determine the contribution of 4f electrons of Eu2+ and Eu3+ ions to the valence band. The resonant and antiresonant photon energies of Eu2+ ions were found as equal to 141 V and 132 eV, respectively and for Eu3+ ions were found as equal to 146 eV and 132 eV, respectively. Contribution of Eu2+4f electrons was found at the valence band edge while for Eu3+ it was located in the region between 3.5 eV and 8.5 eV below the valence band edge.

    Although parent-child communication about sex can significantly affect children's sexual behavior, many parents do not talk to their children about sex. Qualitative research can elucidate parents' attitudes toward and experiences with communicating with their children about sex. In 2007, 16 focus groups were conducted with 131 mothers and fathers of children aged 10-12 in three cities in different regions of the United States. Separate groups were conducted for mothers and fathers, and for black, white and Hispanic parents. Content analysis was used to identify core themes and patterns. Parents believed it is important to talk to their children about sex and believed that doing so can be effective, but many had not done so. Primary barriers were parents' perception that their children are too young and not knowing how to talk to their children about the subject. Parents found it easiest to talk to their children about sex if they had a good parent-child relationship, took advantage of opportunities to talk and began having the discussions when their children were very young. Some differences were noted by parents' race, ethnicity, gender and location. Interventions aimed at encouraging parents to talk to their children about sex should enhance parents' understanding of the stages of children's sexual development and focus on the parents of young children. In addition, interventions should support parents in a range of strategies that complement discussions about sex.

    Many countries in the European Union (EU) have very developed waste management systems. Some of its members have managed to reduce their landfilled waste to values close to zero during the last decade. Thus, European Union legislation is very stringent regarding waste management for their members and candidate countries, too. This raises the following questions: Is it possible for developing and developed countries to comply with the European Union waste legislation, and under what conditions? How did waste management develop in relation to the economic development in the countries of the European Union? The correlation between waste management practices and economic development was analysed for 27 of the European Union Member States for the time period between 1995 and 2007. In addition, a regression analysis was performed to estimate landfilling of waste in relation to gross domestic product for every country. The results showed a strong correlation between the waste management variables and the gross domestic product of the EU27 members. The definition of the municipal solid waste management development phases followed a closer analysis of the relation between gross domestic product and landfilled waste. The municipal solid waste management phases are characterised by high landfilling rates at low gross domestic product levels, and landfilling rates near zero at high gross domestic product levels. Hence the results emphasize the importance of wider understanding of what is required for developing countries to comply with the European Union initiatives, and highlight the importance of allowing developing countries to make their own paths of waste management development. © The Author(s) 2015.

    Eu-doped ZnS quantum dots (QDs) have been synthesized by wet-chemical method and found to form in zinc blende (cubic) structure. Both Eu 2+ and Eu 3+ doped ZnS can be controllably synthesized. The Eu 2+ doped ZnS QDs show broad photoluminescence emission peak around 512 nm, which is from the Eu2+ intra-ion transition of 4f 6d1 – 4f 7, while the Eu 3+ doped samples exhibit narrow emission lines characteristic of transitions between the 4f levels. The investigation of the magnetic properties shows that the Eu 3+ doped samples exhibit signs of ferromagnetism, on the other hand, Eu 2+ dopedmore » samples are paramagnetic of Curie-Weiss type. The incident photon to electron conversion efficiency is increased with the Eu doping, which suggests the QD solar cell efficiency can be enhanced by Eu doping due to widened absorption windows. This is an attractive approach to utilize benign and environmentally friendly wide band gap ZnS QDs in solar cell technology.« less

    A trend towards automation of scientific research has recently resulted in what has been termed "data-driven inquiry" in various disciplines, including physics and biology. The automation of many tasks has been identified as a possible future also for the humanities and the social sciences, particularly in those disciplines concerned with the analysis of text, due to the recent availability of millions of books and news articles in digital format. In the social sciences, the analysis of news media is done largely by hand and in a hypothesis-driven fashion: the scholar needs to formulate a very specific assumption about the patterns that might be in the data, and then set out to verify if they are present or not. In this study, we report what we think is the first large scale content-analysis of cross-linguistic text in the social sciences, by using various artificial intelligence techniques. We analyse 1.3 M news articles in 22 languages detecting a clear structure in the choice of stories covered by the various outlets. This is significantly affected by objective national, geographic, economic and cultural relations among outlets and countries, e.g., outlets from countries sharing strong economic ties are more likely to cover the same stories. We also show that the deviation from average content is significantly correlated with membership to the eurozone, as well as with the year of accession to the EU. While independently making a multitude of small editorial decisions, the leading media of the 27 EU countries, over a period of six months, shaped the contents of the EU mediasphere in a way that reflects its deep geographic, economic and cultural relations. Detecting these subtle signals in a statistically rigorous way would be out of the reach of traditional methods. This analysis demonstrates the power of the available methods for significant automation of media content analysis.

    Highlights: • Tetragonal phase BaTiO{sub 3}:Eu nanocrystals were successfully synthesized using a hydrothermal method. • Under 398 nm excitation, the emissions from Eu{sup 2+} and Eu{sup 3+} ions were observed. • The emission band of Eu{sup 2+} from BaTiO{sub 3}:Eu was observed to broaden with increasing Eu concentration. - Abstract: Tetragonal phase BaTiO{sub 3}:Eu nanocrystals were successfully synthesized using a hydrothermal method and a subsequent calcination treatment. The structures and morphologies of nanocrystals were characterized by X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and scanning electron microscopy. The photoluminescence properties of BaTiO{sub 3}:Eu were investigated in detail. Under 398 nmmore » excitation, the emissions from Eu{sup 2+} and Eu{sup 3+} ions were observed, indicating that Eu{sup 2+} and Eu{sup 3+} ions coexisted in BaTiO{sub 3}:Eu nanocrystals. Especially, the emission band of Eu{sup 2+} from BaTiO{sub 3}:Eu was observed to broaden with increasing Eu concentration. When the Eu concentration was 0.5 mol%, the {sup 5}D{sub 0} → {sup 7}F{sub 0} and {sup 5}D{sub 1} → {sup 7}F{sub 0} emissions were observed.

    The influence of InF{sub 3} doping and remelting on Eu-doped fluorozirconate-based glass ceramics was investigated using near-edge x-ray absorption and optical spectroscopy. It was found that the addition of InF{sub 3} to the melt decreases the Eu{sup 2+}/Eu{sup 3+} mole ratio, while remelting leads to a significant change in the Eu{sup 2+}/Eu{sup 3+} ratio in favor of Eu{sup 2+}. Photoluminescence spectroscopy shows that additional annealing steps lead to the formation of BaCl{sub 2} nanoparticles in the glass. In as-made glass ceramics containing InF{sub 3}, a phase transition of the nanoparticles from hexagonal to orthorhombic structure is observed. This phase transitionmore » is not observed in the remelted glasses studied here.« less

    This study used Self-Determination Theory to examine the motivational processes involved in individuals' engagement in fat talk and its association with unhealthy eating behaviors. Female undergraduate students (N=453) completed an online questionnaire, which assessed general and contextual motivation, importance placed on goals, fat talk, and unhealthy eating behaviors. Structural equation modeling revealed that being generally non-self-determined and placing more importance on extrinsic goals, such as thinness, was associated with fat talk. Fat talk was further associated with non-self-determined motivation for eating regulation, which in turn was associated with unhealthy eating. General self-determination and placing more importance on intrinsic goals, such as health, were not associated with fat talk, but instead, were associated with more adaptive forms of eating regulation and diet quality. Findings further current knowledge on the respective roles of motivation and goals on the engagement in fat talk, and its consequences on eating regulation and behavior.

    Our current research is focused on understanding dopant optimization, growth rate, homogeneity and their impact on the overall performance of KSr2I5:Eu2+ single crystal scintillators. In this work we have investigated the effects of Eu2+ concentration in the potassium strontium iodide matrix, and we found that the concentration needed to maximize the light yield was 4 mol%. In order to assess the effects of the pulling rate, we grew single crystals at 12, 24 and 120 mm/day via the vertical Bridgman technique. For the sample sizes measured (5×5×5 mm3), we found that the crystal grown at the fastest rate of 120 mm/day showed a light yield within ~7% of the more slowly grown boules, and no significant change was observed in the energy resolution. Therefore, light yields from 88,000 to 96,000 ph/MeV and energy resolutions from 2.4 to 3.0% (at 662 keV) were measured for KSr2I5:Eu 4% over a relatively wide range of growth conditions. In order to assess the homogeneity of KSr2I5:Eu 4%, a newly developed micro-resolution X-ray technique was used to map the light yield as a function of excitation position. In the crystals that we studied, we did not observe any significant inhomogeneity other than a smooth gradient due to light collection and self absorption effects.

    Antiferromagnetic ordering of EuCu 2Sb 2 which forms in the tetragonal CaBe 2Ge 2-type structure (space group P4/nmm #129) has been studied using neutron powder diffraction and 151Eu Mössbauer spectroscopy. The room temperature 151Eu isomer shift of –12.8(1) mm/s shows the Eu to be divalent, while the 151Eu hyperfine magnetic field (B hf) reaches 28.7(2) T at 2.1 K, indicating a full Eu 2+ magnetic moment. B hf(T) follows a smoothmore » $$S=\\frac{7}{2}$$ Brillouin function and yields an ordering temperature of 5.1(1) K. Refinement of the neutron diffraction data reveals a collinear A-type antiferromagnetic arrangement with the Eu moments perpendicular to the tetragonal c-axis. As a result, the refined Eu magnetic moment at 0.4 K is 7.08(15) μ B which is the full free-ion moment expected for the Eu 2+ ion with $$S=\\frac{7}{2}$$ and a spectroscopic splitting factor of g = 2.« less

    The water hyacinth (Eichhornia crassipes) has drawn attention as a plant capable of removing pollutants, including toxic metals, from water. The authors are interested in the capacity of the water hyacinth to remediate aquatic environments that have been contaminated with the lanthanide metal, europium Eu(III). Using scanning electron microscopy (SEM) they have been able to determine that Eu(III) is adsorbed onto the surface of the roots from water and that the highest concentration of Eu(III) is on the root hairs. X-ray absorption spectroscopy (XAS) techniques were used to speciate the Eu(III) adsorbed onto the surface of the roots. The XASmore » data for Eu-contaminated water hyacinth roots provides evidence of a Eu-oxygen environment and establishes that Eu(III) is coordinated to 10--11 oxygen atoms at a distance of 2.44 {angstrom}. This likely involves binding of Eu(III) to the root via carboxylate groups and hydration of Eu(III) at the root surface.« less

    Peer Mediated Interventions (PMIs) can be incorporated into integrated early childhood and preschool settings to address socialization impairments observed in children with ASD (Katz & Girolametto, 2013). However, research examining specific PMI strategies with young preschoolers remains limited. The current study examines the efficacy of the Stay, Play, Talk PMI (English, Shafer, Goldstein, & Kaczmerek, 1997) on the social communication skills of young preschool children diagnosed with an Autism Spectrum Disorder (ASD). Each of 3 typically developing children (ages 3-5 years) was paired with a child with an ASD (ages 3-4 years). Typically developing peers were taught to Stay with their friend, Play with their friend, and Talk to their friend. The child dyads played together during two, 20-min weekly sessions for 6-8 weeks. A multiple baseline design across participants was implemented to measure the impact of the Stay Play Talk strategies on social initiations and responses characterized by non-coordinated gestures, gestures, and words. Simulation Modeling Analysis was also conducted to confirm visual analysis. All 3 typical peer buddies and all 3 target children with ASD demonstrated increases in the frequency of their responses, reaching levels that greatly exceeded baseline levels. Further, social reciprocations increased among each dyad above baseline. Social initiations remained variable across dyads. Gains were not maintained two months post intervention. Results of this study corroborated previous findings that support the usefulness of PMIs to improve social communication of young children with ASD (Chan et al., 2009) and suggest an economical, naturally occurring approach to improve social communication during early childhood. Readers will gain knowledge regarding the social communication profile of children with ASD and how this profile can negatively impact language development and peer relationships. In addition, readers will be able to identify the

    2013-01-01

    The reimbursement landscape for new and innovative diabetes devices in Europe is very heterogeneous and nontransparent, with each country employing different mechanisms, pathways, and requirements. This article provides an overview of how diabetes device reimbursement works in the outpatient setting in the five major European Union markets (France, Germany, Italy, Spain, and the United Kingdom; the EU-5). It will be of particular interest to manufacturers of innovative devices. Markets are first categorized as either a centralized or a regionalized reimbursement decision-making system, and implications for device reimbursement are explored. In the second part, specific requirements and success factors for wide reimbursement in the EU-5 are analyzed in detail. Gaining early acceptance by the main influencers (key opinion leaders and payers) is the first step. Equally important is the provision of convincing evidence, be this clinical, health–economic (cost-effectiveness), or a demonstration of cost savings (budget impact). In some countries, local usage data may be a requirement as well. Lastly, as payers’ willingness to pay stems directly from their perceived value of a device, a key success factor and a necessary precondition for manufacturers is to set the right price.

    The EU expanded in 2004 to include eight transition countries, i.e. Central and Eastern European (CEE) and newly independent states of the former Soviet Union, and two other CEE countries are scheduled to join the EU in 2007. Each of these countries has undertaken substantial healthcare reform efforts over the past 15 years. The paths of healthcare reform are diverse for a number of reasons including differences in initial economic, political and structural conditions. The objective of this article is to evaluate the process and preliminary outcomes of healthcare reform in the new EU and candidate countries by analysing trends in aggregate financing, supply and utilisation indicators using data drawn from the WHO Health for All database. The analysis is done in the context of an analytical framework built around common healthcare reform themes. The key reform measures examined include implementing social insurance systems, implementing payment systems that promote efficiency, and removal of excess capacity. The trend analysis highlights the importance of the economic, political and social context in driving the direction and pace of healthcare reform. For example, the transition to social insurance systems was smoother in countries with stronger economies and political commitment to reform. Policies aimed at improving the efficiency of the healthcare system, reducing utilisation and reducing excess capacity were met with some success in all of the countries. However, the reform effort continues as the countries are still addressing the initial challenges of insufficient funding, informal payments, excess capacity and inefficiencies in the provision of healthcare.

    Up to now, orchestrating the coexistence of Eu 2+ and Eu 3+ activators in a single host lattice has been an extremely difficult task, especially for the appearance of the characteristic emission of Eu 2+ and Eu 3+ in order to generate white light. Nevertheless, here we demonstrate a new Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphor with abundant and excellent multichannel luminescence properties. A series of Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphors were prepared through a Pechini-type sol-gel method followed by a reduction process. With excitation of UV/NUV light, the prepared SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphors show not only the characteristic f-f transitions of Eu 3+ ion ( 5 D J → 7 F J,J' , J, J' = 0-3), but also the 5d → 4f transitions of Eu 2+ ion with comparable intensity from 400 to 700 nm in the whole visible spectral region. The luminescence color of the SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor can be tuned from blue, blue-green, white, and orange to orange-red by changing the excitation wavelength, the overall doping concentration of europium ions (Eu 2+ , Eu 3+ ), and the relative ratio of Eu 2+ to Eu 3+ ions to some extent. A single-phase white-light emission has been realized in SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor. The obtained SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor has potential application in the area of NUV white-light-emitting diodes.

    This study examined gender differences in emotion word use during mother-child and father-child conversations. Sixty-five Spanish mothers and fathers and their 4- (M = 53.50, SD = 3.54) and 6-year-old (M = 77.07, SD = 3.94) children participated in this study. Emotion talk was examined during a play-related storytelling task and a reminiscence task (conversation about past experiences). Mothers mentioned a higher proportion of emotion words than did fathers. During the play-related storytelling task, mothers of 4-year-old daughters mentioned a higher proportion of emotion words than did mothers of 4-year-old sons, whereas fathers of 4-year-old daughters directed a higher proportion of emotion words than did fathers of 4-year-old sons during the reminiscence task. No gender differences were found with parents of 6-year-old children. During the reminiscence task daughters mentioned more emotion words with their fathers than with their mothers. Finally, mothers' use of emotion talk was related to whether children used emotion talk in both tasks. Fathers' use of emotion talk was only related to children's emotion talk during the reminiscence task. © 2014 The British Psychological Society.

    This study examined men's perceptions of women engaging in "Fat Talk," a style of conversation that expresses discontent towards one's physical appearance, especially focusing on and criticizing body fat, shape, and weight. Male undergraduates were shown a vignette illustrating a courting scenario wherein the target female's body size was manipulated to be "sexy" and: (a) "lean," (b) "average," or (c) "larger." And to another woman, the men overheard the target female either: (a) self-degrade herself (fat talk) or (b) self-accept herself. As a third independent variable, participants' self esteem was divided into high and low with a median split. Dependent variables included self-created Likert items on his attraction towards the target and perceptions of her health and popularity. Men found the target female to have poorer mental health when he overheard her fat talking versus self-accepting. Further, his desire for a more exclusive committed relationship was stronger when she was described as leaner, especially for the lower self-esteemed men. As a pilot study, this has implications for interventions to decrease women's fat talk and begins research on the dynamic interplay between women's fat talk and heterosexual courtships.

    Anonymous oocyte donation in the EU proceeds only after rigorous screening designed to ensure gamete safety. If anonymous donor gametes originating from outside EU territory are used by EU patients, donor testing must conform to the same standards as if gamete procurement had occurred in the EU. In Ireland, IVF recipients can be matched to anonymous donors in the Ukraine (a non-EU country). This investigation describes the evolution of anonymous oocyte donor screening methods during this period and associated results. Data were reviewed for all participants in an anonymous donor oocyte IVF programme from 2006 to 2009, when testing consistent with contemporary EU screening requirements was performed on all Ukrainian oocyte donors. HIV and hepatitis tests were aggregated from 314 anonymous oocyte donors and 265 recipients. The results included 5,524 Ukrainian women who were interviewed and 314 of these entered the programme (5.7% accession rate). Mean age of anonymous oocyte donors was 27.9 years; all had achieved at least one delivery. No case of hepatitis or HIV was detected at initial screening or at oocyte procurement. This is the first study of HIV and hepatitis incidence specifically among Ukrainian oocyte donors. We find anonymous oocyte donors to be a low-risk group, despite a high background HIV rate. Following full disclosure of the donation process, most Ukrainian women wishing to volunteer as anonymous oocyte donors do not participate. Current EU screening requirements appear adequate to maintain patient safety in the context of anonymous donor oocyte IVF.

    In this paper, the bio-based polyamide (PA ) was melt polymerized from four bio-based monomers. Composites of the bio-based PA and europium complex Eu(TTA)3Phen were prepared through solution mixing using N, N-Dimethylformamide (DMF) and formic acid as the mixed solvent, and then composite fibers were obtained by melt spinning method. The structure and properties of the melt-spun composite fibers were characterized by FTIR and SEM. The results indicated that the Eu(TTA)3Phen complex, with the average diameter below 300 nm, was homogeneously dispersed in the PA matrix. FTIR spectra indicated that the coordination bond between carbonyl of BDIS and Eu(TTA)3Phen complex formed, which was also confirmed by the mechanical properties. The initial modulus and breaking strength of these fibers can arrived at 2.5GPa and 0.3GPa, respectively.

    Cell phone use and text messaging in particular are associated with an increased risk of motor vehicle crashes. However, the frequency with which teenagers use cell phones while driving is still largely unknown. The current study obtained self-reported cell phone use behaviors while driving, including text messaging, along with beliefs about these actions, for a sample of licensed teenage drivers. Questionnaires were mailed to a random sample of 1947 high-school-age teens in 2 large metropolitan areas in North Carolina. Questionnaires were completed and returned by 537 teens, of whom 320 had an intermediate or full driver's license. In total, 45 percent of teens reported using a cell phone in some capacity during their most recent trip. Fifteen percent reported that they only talked on a cell phone, 15 percent sent or read a text message only, and 15 percent both talked and texted. More generally, 12 percent of teens reported that they often talked on a cell phone while driving, 4 percent reported that they often initiated a text conversation while driving, 11 percent said that they often replied to texts, and 23 percent often read text messages. Teens reported using several strategies to reduce the risk associated with using a cell phone while driving. Among teens who had ever talked on a cell phone while driving, 47 percent said that they try to keep their conversations short because they are driving. Among teens who had ever texted while driving, approximately half said that they often wait until it feels safe to read and reply to text messages (58% and 47%, respectively). Most teens surveyed reported having talked or read or sent a text message using a cell phone while driving. Somewhat less than half engaged in one of these behaviors the last time they drove. However, many teens reported using strategies to reduce this risk and in certain instances, cell phone nonuse was the normative behavior.

    surface of solid phase (in Ca/Si<0.8) in the co-presence of Na ions. On the other hand, the concentrations of Na, Ca and Si after 60 days in the solution filtrated through 0.2 μm membrane filter showed the ion exchange of Ca and Eu apparently in the samples of low Ca/Si ratio. Besides, in the samples with high Ca/Si ratio, Ca and Si concentrations in the solution were raised with increment of initial Na concentration. While Na ions may slightly increase the solubility of CSH gel, the CSH samples were stable, mostly maintaining the initial Ca/Si ratio synthesized. Moreover, the Raman spectra showed that the degree of polymerization of silicate chain in CSH samples increased with increasing Na concentration. Such an immobilized Na into the structure of CSH gel did not obstruct the incorporation of Eu{sup 3+} into CSH gel. The results mentioned above suggested that CSH gel (formed as a secondary mineral around the repository) also can retard the migration of radionuclides even if the repository and its surrounding are saturated by saline groundwater.

  11. Ideological Responses to the EU Refugee Crisis

    The 2016 European Union (EU) refugee crisis exposed a fundamental distinction in political attitudes between the political left and right. Previous findings suggest, however, that besides political orientation, ideological strength (i.e., political extremism) is also relevant to understand such distinctive attitudes. Our study reveals that the political right is more anxious, and the political left experiences more self-efficacy, about the refugee crisis. At the same time, the political extremes—at both sides of the spectrum—are more likely than moderates to believe that the solution to this societal problem is simple. Furthermore, both extremes experience more judgmental certainty about their domain-specific knowledge of the refugee crisis, independent of their actual knowledge. Finally, belief in simple solutions mediated the relationship between ideology and judgmental certainty, but only among political extremists. We conclude that both ideological orientation and strength matter to understand citizens’ reactions to the refugee crisis. PMID:29593852

  12. Dividing the common pond: regionalizing EU ocean governance.

    EU ocean policies increasingly incorporate regional measures. Under the long standing Common Fisheries Policy, such measures aim at improving and reforming existing policy, either by taking into account region specific social or ecologic requirements or by establishing procedures and institutions to achieve a regional fit. By contrast, the EU's emerging integrated Marine Environmental Policy was designed to draw heavily on regional procedural and institutional mechanisms from the outset. The developing regional measures raise the question whether they contribute to improving institutional structures governing the use and conservation of EU waters. This article analyzes the existing and future regional measures of the two policies and their varying purposes and scopes. It develops a typology for categorizing the regional aspects and examines the effects of regional measures on EU institutions and the theoretical EU integration debate. Copyright © 2012 Elsevier Ltd.

    The anion photoelectron (PE) spectra of EuH{sup −} and the PE spectrum of overlapping EuOH{sup −} and EuO{sup −} anions are presented and analyzed with supporting results from density functional theory calculations on the various anions and neutrals. Results point to ionically bound, high-spin species. EuH and EuOH anions and neutrals exhibit analogous electronic structures: Transitions from {sup 8}Σ{sup −} anion ground states arising from the 4f{sup 7}σ{sub 6s}{sup 2} superconfiguration to the close-lying neutral {sup 9}Σ{sup −} and {sup 7}Σ{sup −} states arising from the 4f{sup 7}σ{sub 6s} superconfiguration are observed spaced by an energy interval similar to themore » free Eu{sup +} [4f{sup 7}6s] {sup 9}S - {sup 7}S splitting. The electron affinities (EAs) of EuH and EuOH are determined to be 0.771 ± 0.009 eV and 0.700 ± 0.011 eV, respectively. Analysis of spectroscopic features attributed to EuO{sup −} photodetachment is complicated by the likely presence of two energetically competitive electronic states of EuO{sup −} populating the ion beam. However, based on the calculated relative energies of the close-lying anion states arising from the 4f{sup 7}σ{sub 6s} and 4f{sup 6}σ{sub 6s}{sup 2} configurations and the relative energies of the one-electron accessible 4f{sup 7} and 4f{sup 6}σ{sub 6s} neutral states based on ligand-field theory [M. Dulick, E. Murad, and R. F. Barrow, J. Chem. Phys. 85, 385 (1986)], the remaining features are consistent with the 4f{sup 6}σ{sub 6s}{sup 2}  {sup 7}Σ{sup −} and 4f{sup 7}σ{sub 6s}{sup 7}Σ{sup −} anion states lying very close in energy (the former was calculated to be 0.15 eV lower in energy than the latter), though the true anion ground state and neutral EA could not be established unambiguously. Calculations on the various EuO anion and neutral states suggest 4f-orbital overlap with 2p orbitals in species with 4f{sup 6} occupancy.« less

    While the EU Commission has encouraged Member States to combine national and international climate change mitigation measures with subnational environmental policies, there has been little harmonized effort towards the quantification of embodied greenhouse gas (GHG) emissions from household consumption across European regions. This study develops an inventory of carbon footprints associated with household consumption for 177 regions in 27 EU countries, thus, making a key contribution for the incorporation of consumption-based accounting into local decision-making. Footprint calculations are based on consumer expenditure surveys and environmental and trade detail from the EXIOBASE 2.3 multiregional input-output database describing the world economy in 2007 at the detail of 43 countries, 5 rest-of-the-world regions and 200 product sectors. Our analysis highlights the spatial heterogeneity of embodied GHG emissions within multiregional countries with subnational ranges varying widely between 0.6 and 6.5 tCO2e/cap. The significant differences in regional contribution in terms of total and per capita emissions suggest notable differences with regards to climate change responsibility. The study further provides a breakdown of regional emissions by consumption categories (e.g. housing, mobility, food). In addition, our region-level study evaluates driving forces of carbon footprints through a set of socio-economic, geographic and technical factors. Income is singled out as the most important driver for a region’s carbon footprint, although its explanatory power varies significantly across consumption domains. Additional factors that stand out as important on the regional level include household size, urban-rural typology, level of education, expenditure patterns, temperature, resource availability and carbon intensity of the electricity mix. The lack of cross-national region-level studies has so far prevented analysts from drawing broader policy conclusions that hold

  16. EU mitigation potential of harvested wood products.

    2015-12-01

    The new rules for the Land Use, Land Use Change and Forestry sector under the Kyoto Protocol recognized the importance of Harvested Wood Products (HWP) in climate change mitigation. We used the Tier 2 method proposed in the 2013 IPCC KP Supplement to estimate emissions and removals from HWP from 1990 to 2030 in EU-28 countries with three future harvest scenarios (constant historical average, and +/-20% in 2030). For the historical period (2000-2012) our results are consistent with other studies, indicating a HWP sink equal on average to -44.0 Mt CO 2 yr -1 (about 10% of the sink by forest pools). Assuming a constant historical harvest scenario and future distribution of the total harvest among each commodity, the HWP sink decreases to -22.9 Mt CO 2 yr -1 in 2030. The increasing and decreasing harvest scenarios produced a HWP sink of -43.2 and -9.0 Mt CO 2 yr -1 in 2030, respectively. Other factors may play an important role on HWP sink, including: (i) the relative share of different wood products, and (ii) the combined effect of production, import and export on the domestic production of each commodity. Maintaining a constant historical harvest, the HWP sink will slowly tend to saturate, i.e. to approach zero in the long term. The current HWP sink will be maintained only by further increasing the current harvest; however, this will tend to reduce the current sink in forest biomass, at least in the short term. Overall, our results suggest that: (i) there is limited potential for additional HWP sink in the EU; (ii) the HWP mitigation potential should be analyzed in conjunction with other mitigation components (e.g. sink in forest biomass, energy and material substitution by wood).

    Novel LiLa1−x−y(MoO4)2:xSm3+,yEu3+ (in short: LL1−x−yM:xSm3+,yEu3+) double molybdate red phosphors were synthesized by a solid-state reaction at as low temperature as 610 °C. The optimal doping concentration of Sm3+ in LiLa1−x(MoO4)2:xSm3+ (LL1−xM:xSm3+) phosphor is x = 0.05 and higher concentrations lead to emission quenching by the electric dipole—electric dipole mechanism. In the samples co-doped with Eu3+ ions, the absorption spectrum in the near ultraviolet and blue regions became broader and stronger than these of the Sm3+ single-doped samples. The efficient energy transfer from Sm3+ to Eu3+ was found and the energy transfer efficiency was calculated. Under the excitation at 403 nm, the chromaticity coordinates of LL0.95−yM:0.05Sm3+,yEu3+ approach to the NTSC standard values (0.670, 0.330) continuously with increasing Eu3+ doping concentration. The phosphor exhibits high luminous efficiency under near UV or blue light excitation and remarkable thermal stability. At 150 °C, the integrated emission intensity of the Eu3+ remained 85% of the initial intensity at room temperature and the activation energy is calculated to be 0.254 eV. The addition of the LL0.83M:0.05Sm3+,0.12Eu3+ red phosphors can improve the color purity and reduce the correlated color temperature of WLED lamps. Hence, LL1−x−yM:xSm3+,yEu3+ is a promising WLED red phosphor. PMID:29443910

    Could a learning disability-specific death cafe be the key to initiating conversations about death and dying in a safe way? Paula Hopes writes in Learning Disability Practice about a conference on breaking bad news and noted that while some people with learning disabilities were ready to deal with the issues, healthcare professionals were not. Reasons varied from protecting people with learning disabilities to the assumption that they cannot cope with or understand the information. Ms Hopes says nurses should be advocates for people with learning disabilities and provide them with information to engage them in the process of dying. A learning disability-specific death cafe could support nurses to develop confidence in discussing this sensitive issue.

    A comparative μSR study of ceramic samples of the EuMn{sub 2}O{sub 5} and Eu{sub 0.8}Ce{sub 0.2}Mn{sub 2}O{sub 5} multiferroics is performed in the temperature range from 15 to 300 K. It is found that the Ce doping of the EuMn{sub 2}O{sub 5} sample slightly reduces the temperature of the magnetic phase transition from T{sub N} = 45 K for the EuMn{sub 2}O{sub 5} sample to T{sub N} = 42.5 K for the Eu{sub 0.8}Ce{sub 0.2}Mn{sub 2}O{sub 5} sample. Below the temperature T{sub N} for both samples, there are two types of localization of a thermalized muon with different temperature dependencesmore » of the precession frequency of the magnetic moment of the muon in an internal magnetic field. The higher frequency in both samples refers to the initial antiferromagnetic matrix. The behavior of this frequency in Eu{sub 0.8}Ce{sub 0.2}Mn{sub 2}O{sub 5} follows the Curie–Weiss law with the exponent β = 0.29 ± 0.02, which differs from the value β = 0.39 standard for 3D Heisenberg magnetics and is observed in EuMn{sub 2}O{sub 5}, because of the strong frustration of the doped sample. The temperature-independent low frequency is due to the presence of Mn{sup 3+}–Mn{sup 4+} ferromagnetic pairs located along the b axis of the antiferromagnetic matrix and in the regions of phase separation, which contain such ion pairs and e{sub g} electrons recharging them. In both samples, polarization losses are the same (about 20%) and are associated with the formation of Mn{sup 4+}–Mn{sup 4+} + Mu complexes near Mn{sup 3+}–Mn{sup 4+} ferromagnetic pairs. In the temperature interval from 25 to 45 K, the separation of the Eu{sub 0.8}Ce{sub 0.2}Mn{sub 2}O{sub 5} structure into two fractions where the relaxation rates of polarization of muons differ by an order of magnitude is revealed. This effect is due to a change in the state of regions of phase separation (1D superlattices) at the indicated temperatures. Such effect in EuMn{sub 2}O{sub 5} is significantly weaker.« less

    2003-01-01

    A comprehensive experimental study on the antiferromagnetic interlayer exchange coupling in high quality epitaxial all-semiconducting EuSPbSEuS trilayers is reported. The influence of substrates, the thickness of the non-magnetic PbS spacer layer, and of temperature, was investigated by means of SQUID magnetometry. In trilayers with a PbS thickness between 4 and 12 deg A the low temperature hysteresis loops showed the signature of antiferromagnetic coupling. The value of the interlayer exchange coupling energy was determined by simulating the data with a modified Stoner model, including Zeeman, anisotropy, and exchange coupling energies. An important observation was of a strong dependence of the interlayer exchange coupling energy on temperature, consistent with a power law dependence of the exchange coupling constant on the saturation magnetization of the EuS layers. While no theoretical description is readily available, we conjecture that the observed behavior is due to a dependence of the interlayer exchange coupling energy on the exchange splitting of the EuS conduction band.

    We studied the magnetic properties of the antiferromagnets Eu2Ni3Ge5 and EuRhSi3 by measuring their electrical resistivity, specific heat, magnetic susceptibility, magnetization, and thermoelectric power, together with the electrical resistivities at high pressures of up to 15 GPa. These compounds have almost divalent Eu ions at ambient pressure and order antiferromagnetically with a successive change in the antiferromagnetic structure at TN = 19 K and T'N = 17 K in Eu2Ni3Ge5, and at TN = 49 K and T'N = 45 K in EuRhSi3. Magnetic field versus temperature (H-T) phase diagrams were constructed for both compounds from the magnetization measurements. The Néel temperature in Eu2Ni3Ge5 was found to increase up to 7 GPa but to decrease continuously with further increasing pressure, without the so-called valence transition. Under a high pressure of 15 GPa, Kondo-like behavior of the electrical resistivity was observed, suggesting the existence of the heavy-fermion state at low temperatures. A similar trend is likely to occur in EuRhSi3. The present P-T phase diagrams for both compounds are the first cases that are reminiscent of the phase diagram of EuCu2(SixGe1-x)2.

    LiYF4:Eu nanophosphors with a single tetragonal phase are synthesized, and various strategies to enhance the Eu3+ emission from the nanophosphors are investigated. The optimized Eu3+ concentration is 35 mol%, and the red emission peaks due to the 5D0 →7FJ (J = 1 and 2) transitions of Eu3+ ions are further enhanced by energy transfer from a sensitizer pair of Ce3+ and Tb3+. The triple doping of Ce, Tb, and Eu into the LiYF4 host more effectively enhances the Eu3+ emission than the core/shell strategies of LiYF4:Eu(35%)/LiYF4:Ce(15%), Tb(15%) and LiYF4:Ce(15%), Tb(15%)/LiYF4:Eu(35%) architectures. Efficient energy transfer from Ce3+ to Eu3+ through Tb3+ results in three times higher Eu3+ emission intensity from LiYF4:Ce(15%), Tb(15%), Eu(1%) nanophosphors compared with LiYF4:Eu(35%), which contains the optimized Eu3+ concentration. Owing to the energy transfer of Ce3+ → Tb3+ and Ce3+ → Tb3+ → Eu3+, intense green and red emission peaks are observed from LiYF4:Ce(13%), Tb(14%), Eu(1-5%) (LiYF4:Ce, Tb, Eu) nanophosphors, and the intensity ratio of green to red emission is controlled by adjusting the Eu3+ concentration. With increasing Eu3+ concentration, the LiYF4:Ce, Tb, Eu nanophosphors exhibit multicolor emission from green to orange. In addition, the successful incorporation of LiYF4:Ce, Tb, Eu nanophosphors into polydimethylsiloxane (PDMS) facilitates the preparation of highly transparent nanophosphor-PDMS composites that present excellent multicolor tunability.

    Single crystals of EuCu 2As 2 and EuCu 2Sb 2 were grown from CuAs and CuSb self-flux, respectively. The crystallographic, magnetic, thermal, and electronic transport properties of the single crystals were investigated by room-temperature x-ray diffraction (XRD), magnetic susceptibility χ versus temperature T, isothermal magnetization M versus magnetic field H, specific heat C p(T), and electrical resistivity ρ(T) measurements. EuCu 2As 2 crystallizes in the body-centered tetragonal ThCr 2Si 2-type structure (space group I4/mmm), whereas EuCu 2Sb 2 crystallizes in the related primitive tetragonal CaBe 2Ge 2-type structure (space group P4/nmm). The energy-dispersive x-ray spectroscopy and XRD data for themore » EuCu 2Sb 2 crystals showed the presence of vacancies on the Cu sites, yielding the actual composition EuCu 1.82Sb 2. The ρ(T) and C p(T) data reveal metallic character for both EuCu 2As 2 and EuCu 1.82Sb 2. Antiferromagnetic (AFM) ordering is indicated from the χ(T),C p(T), and ρ(T) data for both EuCu 2As 2 (T N = 17.5 K) and EuCu 1.82Sb 2 (T N = 5.1 K). In EuCu 1.82Sb 2, the ordered-state χ(T) and M(H) data suggest either a collinear A-type AFM ordering of Eu +2 spins S = 7/2 or a planar noncollinear AFM structure, with the ordered moments oriented in the tetragonal ab plane in either case. This ordered-moment orientation for the A-type AFM is consistent with calculations with magnetic dipole interactions. As a result, the anisotropic χ(T) and isothermal M(H) data for EuCu 2As 2, also containing Eu +2 spins S = 7/2, strongly deviate from the predictions of molecular field theory for collinear AFM ordering and the AFM structure appears to be both noncollinear and noncoplanar.« less

    Based on low-field magnetization measurements on a series of single crystals, we present a scheme of the Eu2+ spin alignment in EuFe2(As1-xPx)2. We explain observations of the Eu2+ ordering previously reported, reconciling different existing phase diagrams. The magnetic moments of the Eu2+ ions are slightly canted, yielding a ferromagnetic contribution along the c direction that becomes stronger with pressure, until superconductivity sets in. The spin-density wave as well as the superconducting phase coexist with an antiferromagnetic interlayer coupling of the canted spins. Reducing the interlayer distance finally leads to a ferromagnetic Eu2+ interlayer coupling and to the suppression of superconductivity.

    Humans evolved within a microbial ecosystem resulting in an interlinked physiology. The gut microbiota can signal to the brain via the immune system, the vagus nerve or other host-microbe interactions facilitated by gut hormones, regulation of tryptophan metabolism and microbial metabolites such as short chain fatty acids (SCFA), to influence brain development, function and behavior. Emerging evidence suggests that the gut microbiota may play a role in shaping cognitive networks encompassing emotional and social domains in neurodevelopmental disorders. Drawing upon pre-clinical and clinical evidence, we review the potential role of the gut microbiota in the origins and development of social and emotional domains related to Autism spectrum disorders (ASD) and schizophrenia. Small preliminary clinical studies have demonstrated gut microbiota alterations in both ASD and schizophrenia compared to healthy controls. However, we await the further development of mechanistic insights, together with large scale longitudinal clinical trials, that encompass a systems level dimensional approach, to investigate whether promising pre-clinical and initial clinical findings lead to clinical relevance.

  16. Microchannel plate cross-talk mitigation for spatial autocorrelation measurements

    NASA Astrophysics Data System (ADS)

    Lipka, Michał; Parniak, Michał; Wasilewski, Wojciech

    2018-05-01

    Microchannel plates (MCP) are the basis for many spatially resolved single-particle detectors such as ICCD or I-sCMOS cameras employing image intensifiers (II), MCPs with delay-line anodes for the detection of cold gas particles or Cherenkov radiation detectors. However, the spatial characterization provided by an MCP is severely limited by cross-talk between its microchannels, rendering MCP and II ill-suited for autocorrelation measurements. Here, we present a cross-talk subtraction method experimentally exemplified for an I-sCMOS based measurement of pseudo-thermal light second-order intensity autocorrelation function at the single-photon level. The method merely requires a dark counts measurement for calibration. A reference cross-correlation measurement certifies the cross-talk subtraction. While remaining universal for MCP applications, the presented cross-talk subtraction, in particular, simplifies quantum optical setups. With the possibility of autocorrelation measurements, the signal needs no longer to be divided into two camera regions for a cross-correlation measurement, reducing the experimental setup complexity and increasing at least twofold the simultaneously employable camera sensor region.

  6. Suprasegmental information affects processing of talking faces at birth.

    PubMed

    Guellai, Bahia; Mersad, Karima; Streri, Arlette

    2015-02-01

    From birth, newborns show a preference for faces talking a native language compared to silent faces. The present study addresses two questions that remained unanswered by previous research: (a) Does the familiarity with the language play a role in this process and (b) Are all the linguistic and paralinguistic cues necessary in this case? Experiment 1 extended newborns' preference for native speakers to non-native ones. Given that fetuses and newborns are sensitive to the prosodic characteristics of speech, Experiments 2 and 3 presented faces talking native and nonnative languages with the speech stream being low-pass filtered. Results showed that newborns preferred looking at a person who talked to them even when only the prosodic cues were provided for both languages. Nonetheless, a familiarity preference for the previously talking face is observed in the "normal speech" condition (i.e., Experiment 1) and a novelty preference in the "filtered speech" condition (Experiments 2 and 3). This asymmetry reveals that newborns process these two types of stimuli differently and that they may already be sensitive to a mismatch between the articulatory movements of the face and the corresponding speech sounds.

  13. Acceptability of the Talking Touchscreen for Health Literacy Assessment

    PubMed Central

    Yost, Kathleen J.; Webster, Kimberly; Baker, David W.; Jacobs, Elizabeth A.; Anderson, Andy; Hahn, Elizabeth A.

    2012-01-01

    Self-administration of a multimedia health literacy measure in clinic settings is a novel concept. Demonstrated ease of use and acceptability will help predicate the future value of this strategy. We previously demonstrated the acceptability of a “Talking Touchscreen” for health status assessment. For this study, we adapted the touchscreen for self-administration of a new health literacy measure. Primary care patients (n=610) in clinics for underserved populations completed health status and health literacy questions on the Talking Touchscreen and participated in an interview. Participants were 51% female, 10% age 60+, 67% African American, 18% without a high school education, and 14% who had never used a computer. The majority (93%) had no difficulty using the touchscreen, including those who were computer-naïve (87%). Most rated the screen design as very good or excellent (72%), including computer-naïve patients (71%) and older patients (75%). Acceptability of the touchscreen did not differ by health literacy level. The Talking Touchscreen was easy to use and acceptable for self-administration of a new health literacy measure. Self-administration should reduce staff burden and costs, interview bias, and feelings of embarrassment by those with lower literacy. Tools like the Talking Touchscreen may increase exposure of underserved populations to new technologies. PMID:20845195

  16. Behavioral and Neural Correlates of Imagined Walking and Walking-While-Talking in the Elderly

    Blumen, Helena M.; Holtzer, Roee; Brown, Lucy L.; Gazes, Yunglin; Verghese, Joe

    2014-01-01

    Cognition is important for locomotion and gait decline increases the risk for morbidity, mortality, cognitive decline, and dementia. Yet, the neural correlates of gait are not well established, because most neuroimaging methods cannot image the brain during locomotion. Imagined gait protocols overcome this limitation. This study examined the behavioral and neural correlates of a new imagined gait protocol that involved imagined walking (iW), imagined talking (iT), and imagined walking-while-talking (iWWT). In Experiment 1, 82 cognitively-healthy older adults (M = 80.45) walked (W), iW, walked while talking (WWT) and iWWT. Real and imagined walking task times were strongly correlated, particularly real and imagined dual-task times (WWT and iWWT). In Experiment 2, 33 cognitively-healthy older adults (M = 73.03) iW, iT, and iWWT during functional Magnetic Resonance Imaging. A multivariate Ordinal Trend (OrT) Covariance analysis identified a pattern of brain regions that: 1) varied as a function of imagery task difficulty (iW, iT and iWWT), 2) involved cerebellar, precuneus, supplementary motor and other prefrontal regions, and 3) were associated with kinesthetic imagery ratings and behavioral performance during actual WWT. This is the first study to compare the behavioral and neural correlates of imagined gait in single and dual-task situations, an issue that is particularly relevant to elderly populations. These initial findings encourage further research and development of this imagined gait protocol as a tool for improving gait and cognition among the elderly. PMID:24522972

    A lanthanide metal coordination polymer [Eu2(BDC)3(DMSO)(H2O)] was synthesized by the reaction of europium oxide with benzene-1,3-dicarboxylic acid (H2BDC) in a mixed solution of dimethyl sulfoxide (DMSO) and water under hydrothermal conditions. The crystal structure of Eu2(BDC)3(DMSO)(H2O) was characterized by X-ray diffraction (XRD). Thermo-gravimetric analysis of Eu2(BDC)3(DMSO)(H2O) indicated that coordinated DMSO and H2O molecules could be removed to create Eu2(BDC)3(DMSO)(H2O)-py with permanent microporosity, which was also verified by powder XRD (PXRD) and elemental analysis. Both Eu2(BDC)3(DMSO)(H2O) and Eu2(BDC)3(DMSO)(H2O)-py showed mainly Eu-based luminescence and had characteristic emissions in the range 550-700 nm. Copyright © 2015 John Wiley & Sons, Ltd.

  18. Integration of the ferromagnetic insulator EuO onto graphene.

    PubMed

    Swartz, Adrian G; Odenthal, Patrick M; Hao, Yufeng; Ruoff, Rodney S; Kawakami, Roland K

    2012-11-27

    We have demonstrated the deposition of EuO films on graphene by reactive molecular beam epitaxy in a special adsorption-controlled and oxygen-limited regime, which is a critical advance toward the realization of the exchange proximity interaction (EPI). It has been predicted that when the ferromagnetic insulator (FMI) EuO is brought into contact with graphene, an overlap of electronic wave functions at the FMI/graphene interface can induce a large spin splitting inside the graphene. Experimental realization of this effect could lead to new routes for spin manipulation, which is a necessary requirement for a functional spin transistor. Furthermore, EPI could lead to novel spintronic behavior such as controllable magnetoresistance, gate tunable exchange bias, and quantized anomalous Hall effect. However, experimentally, EuO has not yet been integrated onto graphene. Here we report the successful growth of high-quality crystalline EuO on highly oriented pyrolytic graphite and single-layer graphene. The epitaxial EuO layers have (001) orientation and do not induce an observable D peak (defect) in the Raman spectra. Magneto-optic measurements indicate ferromagnetism with a Curie temperature of 69 K, which is the value for bulk EuO. Transport measurements on exfoliated graphene before and after EuO deposition indicate only a slight decrease in mobility.

  19. EU accession: A policy window opportunity for nursing?

    2017-03-01

    European enlargement has been studied in a wide range of policy areas within and beyond health. Yet the impact of EU enlargement upon one of the largest health professions, nursing, has been largely neglected. This paper aims to explore nurse leadership using a comparative case study method in two former Communist countries, Romania and Croatia. Specifically, it considers the extent to which engagement in the EU accession policy-making process provided a policy window for the leaders to formulate and implement a professional agenda while negotiating EU accession. Findings of qualitative interviews and documentary analysis indicate that the mechanisms used to facilitate the accession process were not successful in achieving compliance with the education standards in the Community Acquis, as highlighted in the criteria on the mutual recognition of professional qualifications set out in Directive 2005/36/EC. EU accession capacity building and accession funds were not deployed efficiently to upgrade Romanian and Croatian nursing education towards meeting EU standards. Conflicting views on accession held by the various nursing stakeholders (nursing regulator, nursing union, governmental chief nurse and the professional association) inhibited the setting of a common policy agenda to achieve compliance with EU standards. The study findings suggest a need to critically review EU accession mechanisms and better align leadership at all governance levels. Copyright © 2017 Elsevier B.V. All rights reserved.

  20. Advanced Stirling Radioisotope Generator EU2 Anomaly Investigation

    Lewandowski, Edward J.; Dobbs, Michael W.; Oriti, Salvatore M.

    2016-01-01

    The Advanced Stirling Radioisotope Generator (ASRG) Engineering Unit 2 (EU2) is the highest fidelity electrically-heated Stirling radioisotope generator built to date. NASA Glenn Research Center (GRC) completed the assembly of the ASRG EU2 in September, 2014 using hardware from the now cancelled ASRG flight development project. The ASRG EU2 integrated the first pair of Sunpower's ASC-E3 Stirling convertors (ASC-E3 #1 and #2) in an aluminum generator housing with Lockheed Martin's Engineering Development Unit (EDU) 4 controller. After just 179 hours of EU2 generator operation, the first power fluctuation occurred on ASC-E3 #1. The first power fluctuation occurred 175 hours later on ASC-E3 #2. Over time, the power fluctuations became more frequent on both convertors and larger in magnitude. Eventually the EU2 was shut down in January, 2015. An anomaly investigation was chartered to determine root cause of the power fluctuations and other anomalous observations. A team with members from GRC, Sunpower, and Lockheed Martin conducted a thorough investigation of the EU2 anomalies. Findings from the EU2 disassembly identified proximate causes of the anomalous observations. Discussion of the team's assessment of the primary possible failure theories, root cause, and conclusions is provided. Recommendations are made for future Stirling generator development to address the findings from the anomaly investigation. Additional findings from the investigation are also discussed.

    2015-01-01

    NASA Glenn Research Center (GRC) has recently completed the assembly of a unique Stirling generator test article for laboratory experimentation. Under the Advanced Stirling Radioisotope Generator (ASRG) flight development contract, NASA GRC initiated a task to design and fabricate a flight-like generator for in-house testing. This test article was given the name ASRG Engineering Unit 2 (EU2) as it was effectively the second engineering unit to be built within the ASRG project. The intent of the test article was to duplicate Lockheed Martin's qualification unit ASRG design as much as possible to enable system-level tests not previously possible at GRC. After the cancellation of the ASRG flight development project, the decision was made to continue the EU2 build, and make use of a portion of the hardware from the flight development project. GRC and Lockheed Martin engineers collaborated to develop assembly procedures, leveraging the valuable knowledge gathered by Lockheed Martin during the ASRG development contract. The ASRG EU2 was then assembled per these procedures at GRC with Lockheed Martin engineers on site. The assembly was completed in August 2014. This paper details the components that were used for the assembly, and the assembly process itself.

    Accelerators are basic tools of the experimental physics of elementary particles, nuclear physics, light sources of the fourth generation. They are also used in myriad other applications in research, industry and medicine. For example, there are intensely developed transmutation techniques for nuclear waste from nuclear power and atomic industries. The European Union invests in the development of accelerator infrastructures inside the framework programs to build the European Research Area. The aim is to build new accelerator research infrastructures, develop the existing ones, and generally make the infrastructures more available to competent users. The paper summarizes the first year of activities of the EU FP7 Project Capacities EuCARD -European Coordination of Accelerator R&D. EuCARD is a common venture of 37 European Accelerator Laboratories, Institutes, Universities and Industrial Partners involved in accelerator sciences and technologies. The project, initiated by ESGARD, is an Integrating Activity co-funded by the European Commission under Framework Program 7 - Capacities for a duration of four years, starting April 1st, 2009. Several teams from this country participate actively in this project. The contribution from Polish research teams concerns: photonic and electronic measurement - control systems, RF-gun co-design, thin-film superconducting technology, superconducting transport infrastructures, photon and particle beam measurements and control.

    The International Space Weather Initiative (ISWI) is an international scientific program to understand the external drivers of space weather. The science and applications of space weather has been brought to prominence because of the rapid development of space based technology that is useful for all human beings. The ISWI program has its roots in the successful International Heliophysical Year (IHY) program that ran during 2007 - 2009. The primary objective of the ISWI program is to advance the space weather science by a combination of instrument deployment, analysis and interpretation of space weather data from the deployed instruments in conjunction with space data, and communicate the results to the public and students. Like the IHY, the ISWI will be a grass roots organization with key participation from national coordinators in cooperation with an international steering committee. This talk outlines the ISWI program including its organization and proposed activities.

    The adsorption mechanism of U(VI) and Eu(III) on carbonaceous nanofibers (CNFs) was investigated using batch, IR, XPS, XANES, and EXAFS techniques. The pH-dependent adsorption indicated that the adsorption of U(VI) on the CNFs was significantly higher than the adsorption of Eu(III) at pH < 7.0. The maximum adsorption capacity of the CNFs calculated from the Langmuir model at pH 4.5 and 298 K for U(VI) and Eu(III) were 125 and 91 mg/g, respectively. The CNFs displayed good recyclability and recoverability by regeneration experiments. Based on XPS and XANES analyses, the enrichment of U(VI) and Eu(III) was attributed to the abundant adsorption sites (e.g., -OH and -COOH groups) of the CNFs. IR analysis further demonstrated that -COOH groups were more responsible for U(VI) adsorption. In addition, the remarkable reducing agents of the R-CH2OH groups were responsible for the highly efficient adsorption of U(VI) on the CNFs. The adsorption mechanism of U(VI) on the CNFs at pH 4.5 was shifted from inner- to outer-sphere surface complexation with increasing initial concentration, whereas the surface (co)precipitate (i.e., schoepite) was observed at pH 7.0 by EXAFS spectra. The findings presented herein play an important role in the removal of radionuclides on inexpensive and available carbon-based nanoparticles in environmental cleanup applications.

  7. The Multiplex Network of EU Lobby Organizations.

    The practice of lobbying in the interest of economic or social groups plays an important role in the policy making process of most economies. While no data is available at this stage to examine the success of lobbies in exerting influence on specific policy issues, we perform a first systematic multi-layer network analysis of a large lobby registry. Here we focus on the domains of finance and climate and we combine information on affiliation and client relations from the EU transparency register with information about shareholding and interlocking directorates of firms. We find that the network centrality of lobby organizations has no simple relation with their lobbying budget. Moreover, different layers of the multiplex network provide complementary information to characterize organizations' potential influence. At the aggregate level, it appears that while the domains of finance and climate are separated on the layer of affiliation relations, they become intertwined when economic relations are considered. Because groups of interest differ not only in their budget and network centrality but also in terms of their internal cohesiveness, drawing a map of both connections across and within groups is a precondition to better understand the dynamics of influence on policy making and the forces at play.

    Brain injury triggers a progressive inflammatory response supported by a dynamic astroglia-microglia interplay. We investigated the progressive chronic features of the astroglia-microglia cross talk in the perspective of neuronal effects in a rat model of hippocampal excitotoxic injury. N-Methyl-D-aspartate (NMDA) injection triggered a process characterized within 38 days by atrophy, neuronal loss, and fast astroglia-mediated S100B increase. Microglia reaction varied with the lesion progression. It presented a peak of tumor necrosis factor-α (TNF-α) secretion at one day after the lesion, and a transient YM1 secretion within the first three days. Microglial glucocorticoid receptor expression increased up to day 5, before returning progressively to sham values. To further investigate the astroglia role in the microglia reaction, we performed concomitant transient astroglia ablation with L-α-aminoadipate and NMDA-induced lesion. We observed a striking maintenance of neuronal death associated with enhanced microglial reaction and proliferation, increased YM1 concentration, and decreased TNF-α secretion and glucocorticoid receptor expression. S100B reactivity only increased after astroglia recovery. Our results argue for an initial neuroprotective microglial reaction, with a direct astroglial control of the microglial cytotoxic response. We propose the recovery of the astroglia-microglia cross talk as a tissue priority conducted to ensure a proper cellular coordination that retails brain damage. PMID:25977914

    Current health literacy measures are too long, imprecise, or have questionable equivalence of English and Spanish versions. The purpose of this paper is to describe the development and pilot testing of a new bilingual computer-based health literacy assessment tool. We analyzed literacy data from three large studies. Using a working definition of health literacy, we developed new prose, document and quantitative items in English and Spanish. Items were pilot tested on 97 English- and 134 Spanish-speaking participants to assess item difficulty. Items covered topics relevant to primary care patients and providers. English- and Spanish-speaking participants understood the tasks involved in answering each type of question. The English Talking Touchscreen was easy to use and the English and Spanish items provided good coverage of the difficulty continuum. Qualitative and quantitative results provided useful information on computer acceptability and initial item difficulty. After the items have been administered on the Talking Touchscreen (la Pantalla Parlanchina) to 600 English-speaking (and 600 Spanish-speaking) primary care patients, we will develop a computer adaptive test. This health literacy tool will enable clinicians and researchers to more precisely determine the level at which low health literacy adversely affects health and healthcare utilization.

    In summer 2012 the Italian EU-UNAWE team joined with the South African team in Cape Town, working with the township schools organizing activities at school and also a teachers' training event at the SAAO Observatory. In order to involve in the exchange not only the project's experts but also to the teachers and the children, we organized Skype connections between the Cape town teachers participating in the project and the teachers in Sicily (South Italy) that also participated in one of the Italian training sessions and later between the children of the Italian school and those in Zanemfundo School (Cape Town). Thanks to this chance of seeing each other and talking directly, children have - with huge interest and participation - shared and learned methods, experiences, curiosities. They shared their prepared actual science researches, in order to understand why an equal gnomon cast different shadows at the same time in the two countries. The teachers confronted on curricula, didactic methodologies such as working with a background story during the whole school year, interdisciplinary uses of astronomy, languages etc. The EU-UNAWE project and International or Regional conferences such as LARIM are perfect chances to create exchanges between countries all around the World, and this simple communication model between children and teachers appears like an enormous resource yet to be fully exploited.

  13. High-Precision Measurement of Eu/Eu* in Geological Glasses via LA-ICP-MS Analysis

    NASA Technical Reports Server (NTRS)

    Tang, Ming; McDonough, William F.; Arevalo, Ricardo, Jr.

    2014-01-01

    Elemental fractionation during laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis has been historically documented between refractory and volatile elements. In this work, however, we observed fractionation between light rare earth elements (LREEs) and heavy rare earth elements (HREEs) when using ablation strategies involving large spot sizes (greater than 100 millimeters) and line scanning mode. In addition: (1) ion yields decrease when using spot sizes above 100 millimeters; (2) (Eu/Eu*)(sub raw) (i.e. Europium anomaly) positively correlates with carrier gas (He) flow rate, which provides control over the particle size distribution of the aerosol reaching the ICP; (3) (Eu/Eu*)(sub raw) shows a positive correlation with spot size, and (4) the changes in REE signal intensity, induced by the He flow rate change, roughly correlate with REE condensation temperatures. The REE fractionation is likely driven by the slight but significant difference in their condensation temperatures. Large particles may not be completely dissociated in the ICP and result in preferential evaporation of the less refractory LREEs and thus non-stoichiometric particle-ion conversion. This mechanism may also be responsible for Sm-Eu-Gd fractionation as Eu is less refractory than Sm and Gd. The extent of fractionation depends upon the particle size distribution of the aerosol, which in turn is influenced by the laser parameters and matrix. Ablation pits and lines defined by low aspect ratios produce a higher proportion of large particles than high aspect ratio ablation, as confirmed by measurements of particle size distribution in the laser induced aerosol. Therefore, low aspect ratio ablation introduces particles that cannot be decomposed and/or atomized by the ICP and thus results in exacerbated elemental fractionation. Accurate quantification of REE concentrations and Eu/Eu* requires reduction of large particle production during laser ablation. For the reference

  14. One-pot synthesis and optical properties of Eu3+-doped nanocrystalline TiO2 and ZrO2

    Julián, Beatriz; Corberán, Rosa; Cordoncillo, Eloisa; Escribano, Purificación; Viana, Bruno; Sanchez, Clément

    2005-11-01

    A simple and versatile one-pot sol-gel synthesis of Eu3+-doped nanocrystalline TiO2 and ZrO2 nanomaterials is reported in this paper. It consists of the controlled crystallization of Eu3+-doped TiO2 or ZrO2 nanoparticles from an initial solution containing the metal alkoxide, the lanthanide precursor, a complexing agent and a non-complexing acid. The main interest is that it could be extended to different lanthanide ions and inorganic metal oxides to prepare other multifunctional nanomaterials. The characterization by XRD, HRTEM and SAED techniques showed that the TiO2 and ZrO2 crystallization takes place at very low temperatures (60 °C) and that the crystallite size can be tailored by modifying the synthetic conditions. The optical properties of the resulting materials were studied by emission spectra and decay measurements. Both Eu3+:TiO2 and Eu3+:ZrO2 samples exhibited long lifetime values after removing organic components (τ = 0.7 and 1.3 ms, respectively), but the Eu3+:ZrO2 system is specially promising for photonic applications since its τ value is longer than some reported for other inorganic or hybrid matrices in which Eu3+ ions are complexed. This behaviour has been explained through an effective dispersion of the lanthanide ions within the ZrO2 nanocrystals.

    In this article, we report the change of optical properties for europium chelates on silver nanorods by near-field interactions. The silver rods were fabricated in a seed-growth method followed by depositing thin layers of silica on the surfaces. The europium chelates were physically absorbed in the silica layers on the silver rods. The silver rods were observed to exhibit two plasmon absorption bands from longitudinal and transverse directions, respectively, centered at 394 and 675 nm, close to absorption and emission bands from the Eu(III) chelates. As a result, the immobilized Eu(III) chelates on the silver rods should have strong interactions with the silver nanorods and lead to greatly improved optical properties. The Eu–Ag rod complexes were observed to have enhanced emission intensity up to 240-fold in comparison with the Eu(III) chelates in the metal-free silica templates. This enhancement is much larger than the value for the Eu(III) chelates on the gold rods or silver spheres indicating the presence of stronger interactions for the Eu(III) chelates with the silver rods. The interactions of Eu(III) chelates with the silver rods were also proven by extremely reduced lifetime. Moreover, the Eu–Ag rod complexes exhibited a polarized emission, which was also due to strong interactions of the Eu(III) chelates with the silver rods. All of these features may promise that the Eu(III)–Ag rod complexes have great potential for use as fluorescence imaging agents in biological assays. PMID:24363816

  7. Specificity, cross-talk and adaptation in Interferon signaling

    NASA Astrophysics Data System (ADS)

    Zilman, Anton

    Innate immune system is the first line of defense of higher organisms against pathogens. It coordinates the behavior of millions of cells of multiple types, achieved through numerous signaling molecules. This talk focuses on the signaling specificity of a major class of signaling molecules - Type I Interferons - which are also used therapeutically in the treatment of a number of diseases, such as Hepatitis C, multiple sclerosis and some cancers. Puzzlingly, different Interferons act through the same cell surface receptor but have different effects on the target cells. They also exhibit a strange pattern of temporal cross-talk resulting in a serious clinical problem - loss of response to Interferon therapy. We combined mathematical modeling with quantitative experiments to develop a quantitative model of specificity and adaptation in the Interferon signaling pathway. The model resolves several outstanding experimental puzzles and directly affects the clinical use of Type I Interferons in treatment of viral hepatitis and other diseases.

    Superconducting transmon quantum computing test structures often exhibit significant undesired cross-talk. For experiments with only a handful of qubits this cross-talk can be quantified and understood, and therefore corrected. As quantum computing circuits become more complex, and thereby contain increasing numbers of qubits and resonators, it becomes more vital that the inadvertent coupling between these elements is minimized. The task of accurately controlling each single qubit to the level of precision required throughout the realization of a quantum algorithm is difficult by itself, but coupled with the need of nulling out leakage signals from neighboring qubits or resonators would quickly become impossible. We discuss an approach to solve this critical problem. We acknowledge support from IARPA under contract W911NF-10-1-0324.

    This study examined the relation between the amount of mathematical input in the speech of preschool or day-care teachers and the growth of children's conventional mathematical knowledge over the school year. Three main findings emerged. First, there were marked individual differences in children's conventional mathematical knowledge by 4 years of age that were associated with socioeconomic status. Second, there were dramatic differences in the amount of math-related talk teachers provided. Third, and most important, the amount of teachers' math-related talk was significantly related to the growth of preschoolers' conventional mathematical knowledge over the school year but was unrelated to their math knowledge at the start of the school year.

    The continuing degradation of land and soils is a severe threat to the provision of ecosystem services and economic development. Sustainable use of land and soils are therefore an integral part of the "Agenda 2030" with its 17 Sustainable Development Goals (SDGs) and 169 targets adopted by the UNGeneral Assembly in September 2015. The SDGs provide new opportunities for an ambitious and integrated environmental policy worldwide and in the EU. Among the many relevant targets that directly or indirectly address soils (such as goals on zero hunger, well being, clean energy, climate change, water and sustainable cities), target 15.3 that aims to achieve "a land degradation-neutral world" by 2030 is the most relevant. The concept of "Land Degradation Neutrality" (LDN) is not only about halting the loss of healthy and fertile land, but also actively reversing degradation by restoring land in order to counterbal-ance losses that cannot be avoided. It is a very ambitious target but due to a lack of balancing mechanisms for degradation and restoration in most countries also a new concept. Land Degra-dation Neutrality therefore both needs a scientific conceptual framework as well as a political debate about its implementation and development of instruments. In the EU and its Member States, this debate can also serve as a catalyst to revive the discussion on a common soil policy in Europe after the withdrawal of the proposal for a soil framework directive in 2014. To analyze options for the implementation of target 15.3 in Germany and Europe the research project "Implementing the Sustainable Development Goals on Soils in Germany" (http://ecologic.eu/12876) is currently carried out by the Ecologic Institute on behalf of the Ger-man Environment Agency (UBA) and the German Federal Environment Ministry (BMUB). The project will run until spring 2017 and the session "European Environmental Policies and Sustainability" at the EGU will be an ideal opportunity to present the final

    2005-03-01

    The crosstalk of a multimode interference (MMI)-based demultiplexer is reduced by connecting appropriately designed cascaded MMI filters of high-order. Numerical results show that the designed demultiplexer greatly improves the bandwidth of 20 dB cross-talk loss and has an excellent performance in terms of the insertion loss and chromatic dispersion. Formed with commonly used MMI couplers, the present structure is much easier to implement than other structures.

    The stem cell niche is a specialized environment that dictates stem cell function during development and homeostasis. Here, we show that Dll1, a Notch pathway ligand, is enriched in mammary gland stem cells (MaSCs) and mediates critical interactions with stromal macrophages in the surrounding niche. Conditional deletion of Dll1 reduced the number of MaSCs and impaired ductal morphogenesis in the mammary gland. Moreover, MaSC-expressed Dll1 activates Notch signaling in stromal macrophages, increasing their expression of Wnt family ligands such as Wnt3, Wnt10A, and Wnt16, thereby initiating a feed back loop that promotes the function of Dll1 + MaSCs. Together, these findings reveal functionally important cross-talk between MaSCs and their macrophageal niche through Dll1/Notch-mediated signaling.

    Wilken, Marlene; Nunn, Martha

    2017-08-01

    Purpose The purpose of this study was to determine if the use of both the Talking Circles (TCs) and diabetes self-management education (DSME) results in better adherence and outcomes for diabetes self-management than DSME alone in American Indians (AIs) with type 2 diabetes mellitus (T2DM). Methods A quasiexperimental, mixed-methods approach was used for AIs with uncontrolled T2DM, defined by an A1C > 7.0%. The experimental group (n = 20) participated in a TC and received DSME. The control group (n = 19) received only DSME. Talking Circles were audio-taped and analyzed qualitatively. Quantitative data were analyzed using the generalized estimating equation and Fisher exact test for all study participants every 3 months for 1 year. Results Themes identified by TC participants were spirituality, gratitude, and sharing. Major topics of discussion were the experiences of living with T2DM, including challenges and coping. Evidence of positive trends for the experimental group who received the TC intervention included lower systolic blood pressure, lower A1C, lower weight over time, and increased adherence without incentives. Conclusion Talking Circles may have utility in improving adherence in AI adults with uncontrolled T2DM. Further studies are warranted, including extending the use of the TCs after completion of DSME sessions.

  16. A Conceptual Framework of Mapping Access to Health Care across EU Countries: The Patient Access Initiative.

    PubMed

    Souliotis, Kyriakos; Hasardzhiev, Stanimir; Agapidaki, Eirini

    Research evidence suggests that access to health care is the key influential factor for improved population health outcomes and health care system sustainability. Although the importance of addressing barriers in access to health care across European countries is well documented, little has been done to improve the situation. This is due to different definitions, approaches and policies, and partly due to persisting disparities in access within and between European countries. To bridge this gap, the Patient Access Partnership (PACT) developed (a) the '5As' definition of access, which details the five critical elements (adequacy, accessibility, affordability, appropriateness, and availability) of access to health care, (b) a multi-stakeholders' approach for mapping access, and (c) a 13-item questionnaire based on the 5As definition in an effort to address these obstacles and to identify best practices. These tools are expected to contribute effectively to addressing access barriers in practice, by suggesting a common framework and facilitating the exchange of knowledge and expertise, in order to improve access to health care between and within European countries. © 2016 S.

  17. An experimental investigation of the consequences and social functions of fat talk in friendship groups.

    PubMed

    Cruwys, Tegan; Leverington, Carly T; Sheldon, Anne M

    2016-01-01

    Fat talk is a form of self-degrading, thin-ideal endorsing communication that occurs within female friendship groups. Previous studies have suggested negative associations with wellbeing, but have been predominantly correlational and based on self-report. This study aimed to assess the causal relationship between fat talk and the correlates of disordered eating (thin-ideal internalization, body dissatisfaction, negative affect, and dieting intentions) by experimentally manipulating fat talk in existing friendship groups and measuring naturalistic expression of fat talk and its effects. Participants were 85 women aged 17-25 who completed the experiment in friendship pairs. They were randomly assigned to a condition in which their friend expressed fat talk, positive body talk, or neutral talk. This study found evidence of a causal link between listening to friends fat talk and increased correlates of disordered eating. The negative effects of listening to fat talk were fully mediated by fat talk expression. This study also revealed a social function of fat talk, whereby participants rated their friends more positively when they were perceived to behave consistently with group norms, either pro- or anti-fat talk. Positive body talk showed none of the negative effects of fat talk, and was considered socially acceptable regardless of existing friendship group norms. These findings indicate that fat talk is a mechanism through which the thin ideal is transmitted between individuals. Interventions at the level of the friendship group to challenge norms and communication styles may break the link between societal risk factors and individual risk of eating disorders. © 2015 Wiley Periodicals, Inc.

    2010-05-01

    EuroANDRILL is a new initiative to create a European network with the goal to increase future involvement of European countries in the ANDRILL [ANtarctic geological DRILLing] Programme. Antarctica has been heavily glaciated for approximately 34 million years, but its ice sheets have fluctuated considerably and are one of the major driving forces for changes in climate throughout the Cenozoic Era. The spatial scale and temporal pattern of these fluctuations is subject to considerable debate. Understanding the response of large ice masses to climatic forcing is of vital importance because ice volume variations drive global sea level changes and also alter the capacity of ice sheets and sea-ice to act as major heat sinks/insulators. It is particularly important to assess the stability of the cryosphere in the face of rising CO2 levels, as modelling of the climate shift from a warm, vegetated Antarctica to a cold, ice-covered state 34 million years ago suggests a powerful greenhouse gas influence. As Antarctica is the major driver of Earth's climate and sea level, much effort has been expended in deriving models of its behaviour. Some of these models have been successfully validated against modern conditions. EuroANDRILL will provide a coherent, integrated platform for European leadership and involvement in the international ANDRILL programme. The coordination and networking provided by EuroANDRILL will seek to expand participation by European nations, institutions, and individual scientists in the study of the geologic history of the polar regions and their paleoclimatic significance. During the IPY, ANDRILL has been a highly visible and successful programme. This programme seeks to expand on this legacy beyond the IPY and make these contributions sustainable in the European Research Area through networking of research projects and future planning efforts, which establish Europe as a key player in future polar sediment and rock drilling.

    We report the crystal growth and scintillation properties of two new ternary metal halide scintillators, RbSr2Br5 and RbSr2I5, activated with divalent europium. Transparent 7 mm diameter single crystals with 2.5% Eu2+ were grown in evacuated quartz ampoules via the Bridgman technique. RbSr2Br5 and RbSr2I5 have monoclinic crystal structures with densities of 4.18 g/cm3 and 4.55 g/cm3 respectively. These materials are hygroscopic and have some intrinsic radioactivity due to the presence of 87Rb. Luminescence properties typical of the 5d-4f radiative transition in Eu2+ were observed. The X-ray excited emissions consisted of singular peaks centered at 429 nm for RbSr2Br5:Eu 2.5% and 445 nm for RbSr2I4:Eu 2.5%. RbSr2Br5:Eu 2.5% had a light yield of 64,700 photons/MeV, with an energy resolution of 4.0%, and RbSr2I5:Eu 2.5% had a light yield of 90,400 ph/MeV with an energy resolution of 3.0% at 662 keV. Both crystals have an excellent proportional response over a wide range of gamma-ray energies.

    2018-05-01

    Consumers are increasingly turning their attention to the quality and origin of products that they consume. European Union (EU) quality schemes are associated with a label, which was introduced to allow consumers to perform an informed choice and to protect producers from unfair practices. This present study provides an overview of the last 25 years of EU quality schemes [Protected Designations of Origin (PDO), Protected Geographical Indications (PGI) and Traditional Specialities Guaranteed (TSG)] on agricultural products and foodstuffs across the 28 EU Member States. According to the results, it was possible to conclude that Southern European countries have the highest number of registered products. The most used EU quality scheme is PGI, followed by PDO. Concerning the analysis of the evolution in the last 25 years, the number of registered products among EU Member States has increased significantly. The fruit, vegetables and cereals (fresh or processed) category is the one that accounts for the highest percentage (26.8%) of registered products, followed by cheeses and meat products (cooked, salted, smoked) categories, with 17.2% and 13.5%, respectively.

  1. Effect of Eu magnetism on the electronic properties of the candidate Dirac material EuMnBi2

    The crystal structure and physical properties of the layered material EuMnBi2 have been characterized by measurements on single crystals. EuMnBi2 is isostructural with the Dirac material SrMnBi2 based on single-crystal x-ray diffraction, crystallizing in the I4/mmm space group (No. 139). Magnetic susceptibility measurements suggest antiferromagnetic (AFM) ordering of moments on divalent Eu ions near TN=22 K. For low fields, the ordered Eu moments are aligned along the c axis, and a spin flop is observed near 5.4 T at 5 K. The moment is not saturated in an applied field of 13 T at 5 K, which is uncommon for compounds containing Eu2+. The magnetic behavior suggests an anisotropy enhancement via interaction between Eu and the Mn moments that appear to be ordered antiferromagnetically below ≈310 K. A large increase in the magnetoresistance is observed across the spin flop, with absolute magnetoresistance reaching ≈650% at 5 K and 12 T. Hall effect measurements reveal a decrease in the carrier density below TN, which implies a manipulation of the Fermi surface by magnetism on the sites surrounding the Bi square nets that lead to Dirac cones in this family of materials.

    Eu 2+-activated phosphors are being widely used in illuminations and displays. Some of these phosphors feature an extremely broad and red-shifted Eu 2+ emission band; however, convincing explanation of this phenomenon is lacking. Here we report a new localized/delocalized emitting state of Eu 2+ ions in a new hexagonal EuAl 2O 4 phosphor whose Eu 2+ luminescence exhibits a very large bandwidth and an extremely large Stokes shift. At 77 K, two luminescent sites responsible for 550 nm and 645 nm broadband emissions are recognized, while at room temperature only the 645 nm emission band emits. The 645 nm emissionmore » exhibits a typical radiative lifetime of 1.27 μs and an unusually large Stokes shift of 0.92 eV. We identify the 645 nm emission as originating from a new type of emitting state whose composition is predominantly that of localized 4f 65d character but which also contains a complementary component with delocalized conduction-band-like character. This investigation gives new insights into a unique type of Eu 2+ luminescence in solids whose emission exhibits both a very large bandwidth and an extremely large Stokes shift.« less

  3. Scientifically speaking: Identifying, analyzing, and promoting science talk in small groups

    NASA Astrophysics Data System (ADS)

    Holthuis, Nicole Inamine

    In this dissertation I define, document, and analyze the nature of students' science talk as they work in cooperative learning groups. Three questions form the basis of this research. First, what is science talk? Second, how much and what kind of science talk did students do? And, third, what conditions help promote or inhibit students' science talk? This study was conducted in a total of six classrooms in three high schools. I videotaped and audiotaped students as they worked in small groups during the course of an ecology unit. I analyzed this videotape data and field notes using both quantitative and qualitative methods. I define science talk as talk that serves to move students along in terms of the science (both content and process) required or suggested by the activity. More specifically, I identified five epistemological characteristics that delineate what counts as scientific knowledge and, subsequently, science talk. From this definition, I developed an analytic framework and science talk observation instrument to document the quantity and level of student and teacher talk during groupwork. Analysis of the data from this instrument indicates that the overall level of students' science talk is considerable and students do significantly more science talk than school talk. I also found that while the overall level and type of science talk does not vary by class or by school, it does vary by activity type. Finally, my analysis suggests that science talk does not vary by gender composition of the group. I explored the classroom conditions that promote or inhibit science talk during groupwork. My findings suggest that, among other things, teachers can promote science talk by delegating authority to students, by emphasizing content and the big idea, by implementing open-ended tasks, and by modeling science talk. In conclusion, the findings described in this dissertation point teachers and researchers toward ways in which they may improve practice in order to

    Folic acid (FA) was immobilized on Eu(3+)-doped nanoporous silica spheres (Eu:NPSs) through mediation of the 3-aminopropyltriethoxysilane adlayer. The ordered nanopores of Eu:NPS were preserved by the immobilization. The FA-immobilized Eu:NPSs showed the characteristic photoluminescence peak due to interactions between the FA molecules and Eu(3+) ions, and highly dispersed stability in phosphate buffered saline.

    Within Western cultural traditions, the idea that parents should talk about the death of their child with each other is deeply rooted. However, across bereaved parent couples there are wide variations in communication about their grief with each other. In this study, we explored the experiences of bereaved couples related to the process of talking and not talking. We used a thematic coding approach to analyze 20 interviews with 26 bereaved parents (11 interviewed as couples, four as individuals). Four main meanings emerged out of our analysis: not talking because of the inadequacy and pointlessness of words in grief, not talking as a way to regulate emotions in daily life, not talking as an expression of a personal, intimate process, and not talking because the partner has the same loss but a different grief process. In addition, we found that the process of talking and not talking can partly be understood as an emotional responsive process on an intrapersonal and interpersonal level. In this process partners search for a bearable distance from their own grief and their partner's, and attune with their relational context. A better understanding of this process is sought in a dialectical approach, emphasizing the value of both talking and not talking in a tense relationship with each other. Implications for clinical work are described. © 2017 Family Process Institute.

    Inorganic scintillators are very important in medical and industrial measuring systems in the detection and measurement of ionizing radiation. In addition to Ce 3+, a widely used dopant ion in oxide scintillators, divalent Europium (Eu 2+) has shown promise as a high-luminescence, fast-response luminescence center useful in the detection of ionizing radiation. In this research, aluminum oxide (Al 2O 3) was studied as a host material for the divalent europium ion. Polycrystalline samples of Eu 2+-doped translucent Al 2O 3 were fabricated, and room temperature luminescence behavior was observed. Al 2O 3 ceramics doped with 0.1 at% Eu 2+ weremore » fabricated with a relative density of 99.75% theoretical density and in-line transmittance of 22% at a wavelength of 800 nm. The ceramics were processed by a gel-casting method, followed by sintering under high vacuum. The gelling agent, a copolymer of isobutylene and maleic anhydride, is marketed under the commercial name ISOBAM, and has the advantage of simultaneously acting as both a gelling agent and as a dispersant. The microstructure and composition of the vacuum-sintered Eu 2+:Al 2O 3 were characterized by Scanning Electric Microscopy (SEM), Transmission Electron Microscopy (TEM), and Energy-dispersive X-ray spectroscopy (EDS). The phase composition was determined by X-ray diffraction measurements (XRD) combined with Rietveld analysis. The photoluminescence behavior of the Eu 2+:Al 2O 3 was characterized using UV light as the excitation source, which emitted blue emission at 440 nm. The radio-luminescence of Eu 2+:Al 2O 3 was investigated by illumination with X-ray radiation, showing three emission bands at 376 nm, 575 nm and 698 nm. Furthermore, multiple level traps at different depths were detected in the Eu 2+:Al 2O 3 by employing thermoluminescence measurements.« less

  8. Pesticide authorization in the EU-environment unprotected?

    Pesticides constitute an integral part of high-intensity European agriculture. Prior to their authorization, a highly elaborated environmental risk assessment is mandatory according to EU pesticide legislation, i.e., Regulation (EC) No. 1107/2009. However, no field data-based evaluation of the risk assessment outcome, i.e., the regulatory acceptable concentrations (RACs), and therefore of the overall protectiveness of EU pesticide regulations exists. We conducted here a comprehensive meta-analysis using peer-reviewed literature on agricultural insecticide concentrations in EU surface waters and evaluated associated risks using the RACs derived from official European pesticide registration documents. As a result, 44.7 % of the 1566 cases of measured insecticide concentrations (MICs) in EU surface waters exceeded their respective RACs. It follows that current EU pesticide regulations do not protect the aquatic environment and that insecticides threaten aquatic biodiversity. RAC exceedances were significantly higher for insecticides authorized using conservative tier-I RACs and for more recently developed insecticide classes, i.e., pyrethroids. In addition, we identified higher risks, e.g., for smaller surface waters that are specifically considered in the regulatory risk assessment schemes. We illustrate the shortcomings of the EU regulatory risk assessment using two case studies that contextualize the respective risk assessment outcomes to field exposure. Overall, our meta-analysis challenges the field relevance and protectiveness of the regulatory environmental risk assessment conducted for pesticide authorization in the EU and indicates that critical revisions of related pesticide regulations and effective mitigation measures are urgently needed to substantially reduce the environmental risks arising from agricultural insecticide use.

  19. Environmental Kuznets curve for EU agriculture: empirical evidence from new entrant EU countries.

    PubMed

    2017-06-01

    The present work examines the intertemporal causal relationship between environmental damage from carbon emissions released by agriculture per 1000 ha of utilized agriculture area and economic performance in the sector of agriculture as described by net value added per capita. The autoregressive distributed lag bounds testing approach is employed to examine this linkage, for three new entrant EU countries, namely, Bulgaria, Czech Republic, and Hungary. The environmental Kuznets hypothesis is confirmed in the long run for Bulgaria and Czech Republic while in the short run is validated only for the case of Czech Republic. The results indicate that the adoption of environment-friendly farming practices and crops' selection does not secure simultaneous high economic and environmental performance at least in the short run for our sample countries and also in the long run for Hungary necessitating the modification of the agro-environmental measures adopted to make those two targets complementary and not mutually exclusive for a farmer.

  20. Characterization of the Advanced Stirling Radioisotope Generator EU2

    NASA Technical Reports Server (NTRS)

    Lewandowski, Edward J.; Oriti, Salvatore M.; Schifer, Nicholas A.

    2015-01-01

    Significant progress was made developing the Advanced Stirling Radioisotope Generator (ASRG), a 140-watt radioisotope power system. While the ASRG flight development project has ended, the hardware that was designed and built under the project is continuing to be tested to support future Stirling-based power system development. NASA GRC recently completed the assembly of the ASRG Engineering Unit 2 (EU2). The ASRG EU2 consists of the first pair of Sunpower's ASC-E3 Stirling convertors mounted in an aluminum housing, and Lockheed Martin's Engineering Development Unit (EDU) 4 controller (a fourth generation controller). The ASC-E3 convertors and Generator Housing Assembly (GHA) closely match the intended ASRG Qualification Unit flight design. A series of tests were conducted to characterize the EU2, its controller, and the convertors in the flight-like GHA. The GHA contained an argon cover gas for these tests. The tests included: measurement of convertor, controller, and generator performance and efficiency, quantification of control authority of the controller, disturbance force measurement with varying piston phase and piston amplitude, and measurement of the effect of spacecraft DC bus voltage on EU2 performance. The results of these tests are discussed and summarized, providing a basic understanding of EU2 characteristics and the performance and capability of the EDU 4 controller.
