    Bibliometric methods are used to analyze quantitatively the journal physica status solidi (pss) 50 years after its inception. First, the coverage of the journal by the relevant citation indices accessible under the Web of Science (WoS) and the field-specific INSPEC database is examined. The number of papers published per year by the journal as a whole and by the specific pss series is given. The time evolution of the pss output in terms of papers per year is compared with the output evolution of some major competing journals in the field of condensed-matter physics. The top-12 most frequently cited pss papers published within the complete time period 1961-2010 and within the two separate time periods 1974-1989 and 1990-2010 (before and after the German reunification) are listed. The citation time curves (citation history) of the three most frequently cited pss papers are presented. Furthermore, the Journal Impact Factors (JIFs) of the pss journal series (a) and (b) are discussed and their time evolution is shown. Moreover, the distribution of the pss papers over their document types and the authors is given. The countries of authors are ranked for the complete time period 1961-2010 as well as for the time periods 1973-1989 and 1990-2010. The complete ensemble of the citing papers of the pss papers is analyzed and discussed. The journals citing most often the pss papers published in the year 2000 are listed. Finally, the distribution of the pss papers over the various subject areas and classification terms based on the INSPEC database is tabled. (Copyright copyright 2011 WILEY-VCH Verlag GmbH and Co.

    2015-01-01

    Questo eserciziario nasce dalla raccolta di problemi d'esame assegnati agli studenti del corso di Struttura della Materia, che si colloca al confine fra il Corso Triennale e quello Magistrale. Alla fine di ciascun capitolo si trova un riepilogo ragionato di formule utili, e l’ultima parte del volume è dedicata alle unità di misura, alle formule di Meccanica Quantistica e alle tecniche per manipolare il momento angolare, i metodi variazionale e quello perturbativo elementare. Quasi tutti i problemi sono applicazioni della Meccanica Quantistica, anche se si utilizzano nozioni di Termodinamica, Meccanica ed Elettromagnetismo. I problemi di questo manuale differiscono rispetto a quelli che caratterizzano libri di Fisica Teorica (che possono anche essere astratti o rilevanti per l'Astrofisica o le Interazioni Deboli, soprattutto nel fatto che) soprattutto nel fatto che questi devono alla fine determinare dei valori realistici di misure standard su atomi molecole o solidi.

    2007-01-01

    La meccanica dei solidi rappresenta un corpus di conoscenze di formidabile robustezza concettuale, di raffinata eleganza matematico-formale e di grandissima utilita’ applicativa. Come tale ha una valenza formativa molto forte in diversi campi delle scienze naturali (fisica della materia, scienza dei materiali), ingegneristiche (scienza delle costruzioni, ingegneria strutturale e meccanica) e matematiche (matematica applicata). La teoria della elasticita’costituisce inoltre uno dei punti-cardine su cui si articola il moderno paradigma di ricerca detto "modellazione multi-scala dei materiali", secondo il quale le proprieta’ di un materiale sono descritte tramite la concorrenza di metodi teorici affatto diversi: mentre alla nanoscala opera la meccanica quantistica, alla micro- e meso-scala opera il continuo. La conoscenza del continuo elastico abilita lo Studente di Fisica, di Scienza dei Materiali, di Matematica o l’Allievo Ingegnere a confrontarsi con questo moderno e affascinate strumento di ricerca s...

    SWM (Solid Waste Management) systems have always been compatible with the societal need at every point of time. In 1950's it was oriented towards maintaining public health standards mainly to control infectious diseases. While in 1970's energy generation was considered as the vital aspect of the system. In 1990's reduction in waste generation and recycling were officially incorporated in the waste management regulation. By enacting basic law in 2000 A.D.; the society is poised to become a recycling based society in its drive towards sustainable society. The document explain the actual solid waste strategic management, and related issues, in Japan. [Italian] Nel corso della storia la gestione dei rifiuti solidi si e sempre resa compatibile con le esigenze della societa espresse in quel determinato momento. Negli anni '50 la gestione era orientata al mantenimento di determinati standard di salute pubblica, principalmente rivolti al controllo della diffusione di malattie infettive, mentre negli anni '70 la produzione di energia dai rifiuti era considerato l'aspetto prioritario per la corretta risoluzione del problema gestionale dei rifiuti. Negli anni '90 la riduzione della produzione dei rifiuti e il loro riciclaggio sono stati inseriti, come principio, nei documenti per la regolamentazione della gestione dei rifiuti solidi. Con l'approvazione di specifiche normative quadro, a partire dai primi anni del 2000, la societa si avvia ad essere una societa basata sul riciclaggio, nel suo cammino verso la sostenibilita. Nel testo si esaminano i principali aspetti strategici della gestione dei rifiuti solidi, e problematiche annesse, in Giappone.

    The preparation and characterization of terbium doped zinc aluminate photoluminescent films obtained by ultrasonic spray pyrolysis deposition process are described. Variations on doping concentrations in the start spraying solution and substrate temperatures were studied. XRD measurements on these films showed that the crystalline structure depends on the substrate temperature. For an excitation wavelength of 242 nm, all the photoluminescence spectra show peaks located at 488 nm, 546 nm, 589 nm and 621 nm. The photoluminescence intensity reaches values practically constant for the samples deposited at substrate temperatures higher than 400 °C. In this case, concentration quenching of the photoluminescence appears at doping concentrations greater than 0.93 atomic percent into the films. The surface morphology characteristics of the films deposited on glass and silicon substrates, as a function of the deposition temperature, are presented.

    Single crystals of [(CH3)2 NH2]5Cd2CuCl11 have been grown and their dielectric and optical properties have been studied. Electric permittivity, losses and linear optic birefringence measurements have shown that the obtained new crystal is isomorphous with the original one - [(CH3)2 NH2]5Cd3Cl11. Phase transitions were observed at 175 K (continuous) and 120 K (first order). It means that partial replacing of cadmium atoms by copper ones does not change the structure and the heavy Cd2CuCl11-2 anions do not influence significantly the interaction of dimethylammonium cations.

    Ellmer, K.; Mientus, R.; Seeger, S.; Weiß, V.

    2004-11-01

    Highly (001)-oriented WS2-x films were grown onto oxidized silicon substrates by reactive magnetron sputtering from a metallic tungsten target in argon-hydrogen sulfide mixtures. The best films with respect to the van-der-Waals orientation, i.e. with the (001) planes parallel to the substrate surface, were grown by excitation of the plasma with radio frequency of 27.12 MHz. These films exhibit the largest grains and the lowest film strain. It is shown that this effect is not due to the lower deposition rate at this high excitation frequency. Instead it was found that the lower DC voltage at the sputtering target is advantageous for the film growth since the bombardment of the growing film by highly energetic particles is avoided by this type of plasma excitation.

    2006-01-01

    The purpose of the article is to propose 'decidability' as a new criterion for theories aiming at analysing empirical texts. Originally, 'decidability' was developed as a formal concept (Gödel 1931). In this paper, I show some of the consequences of applying the criterion of decidability to text ...... analyses as conducted within a cognitively motivated theory of discourse....

    A language is factorial if it is closed under taking factors (i.e. contiguous subwords). Every factorial language can be described by an antidictionary, i.e. a minimal set of forbidden factors. We show that the problem of deciding whether a factorial language given by a finite antidictionary is well-quasi-ordered under the factor containment relation can be solved in polynomial time. © 2013 Springer-Verlag Berlin Heidelberg.

    The new environmental regulations in Europe require higher standards for design and management of new landfills. Municipal solid wastes (MSW) have to be pretreated before land filling, in order to enable strong reduction of landfill emissions and environmental impact. The paper briefly describes the role of new landfills in solid waste management and the influence of some measures on the reduction of emissions and environmental impact. [Italian] In base alle nuove Direttive italiane e comunitarie, la discarica controllata e' destinata ad avere anche in futuro un ruolo di primo piano nella gestione dei rifiuti solidi urbani. In particolare, saranno destinati a smaltimento in discarica rifiuti pretrattati che garantiscano limitata putrescibilita' e minore impatto ambientale della discarica. Nell'articolo vengono esposte alcune considerazioni sul ruolo delle discariche nelle moderne strategie di smaltimento dei rifiuti solidi urbani, sugli effetti del pretrattamento dei rifiuti sulle emissioni di biogas e percolato dalle discariche e sulle caratteristiche idrauliche e meccaniche delle discariche per rifiuti pretrattati.

    The technical, economical and financial estimate of differentiated mono and multimaterial waste collection methods is the subject of this research. This is referred to a Calabrian (Italy) territorial ambit and it is divided in two stages: the first one is based on the evaluation of the possible technical achievement of the two alternatives; the second one lies in the formulation of foreseeing economic and capital accounts to which operative and financial methods are applied for the evaluation of investments. [Italian] La ricerca ha come oggetto la valutazione tecnica ed economico-finanziaria dei sistemi per la raccolta differenziata mono e multi-materiale dei rifiuti solidi urbani. Specificatamente riferita ad un ambito territoriale calabrese, si articola in due fasi: la prima e' focalizzata sulla realizzabilita' tecnica delle due alternative; la seconda consiste nella formulazione dei conti previsionali economico e di capitale, cui vengono, quindi, applicati i metodi operativi e finanziari per la valutazione degli investimenti.

  1. Deciding as Intentional Action: Control over Decisions

    Science.gov (United States)

    Shepherd, Joshua

    2015-01-01

    Common-sense folk psychology and mainstream philosophy of action agree about decisions: these are under an agent's direct control, and are thus intentional actions for which agents can be held responsible. I begin this paper by presenting a problem for this view. In short, since the content of the motivational attitudes that drive deliberation and decision remains open-ended until the moment of decision, it is unclear how agents can be thought to exercise control over what they decide at the moment of deciding. I note that this problem might motivate a non-actional view of deciding—a view that decisions are not actions, but are instead passive events of intention acquisition. For without an understanding of how an agent might exercise control over what is decided at the moment of deciding, we lack a good reason for maintaining commitment to an actional view of deciding. However, I then offer the required account of how agents exercise control over decisions at the moment of deciding. Crucial to this account is an understanding of the relation of practical deliberation to deciding, an understanding of skilled deliberative activity, and the role of attention in the mental action of deciding.

    2014-10-01

    We introduce a probabilistic modal (dynamic-epistemic) quantum logic PLQP for reasoning about quantum algorithms. We illustrate its expressivity by using it to encode the correctness of the well-known quantum search algorithm, as well as of a quantum protocol known to solve one of the paradigmatic tasks from classical distributed computing (the leader election problem). We also provide a general method (extending an idea employed in the decidability proof in Dunn et al. (J. Symb. Log. 70:353-359, 2005)) for proving the decidability of a range of quantum logics, interpreted on finite-dimensional Hilbert spaces. We give general conditions for the applicability of this method, and in particular we apply it to prove the decidability of PLQP.

    2016-01-01

    We study risk taking on behalf of others, both when choices involve losses and when they do not. A large-scale incentivized experiment with subjects randomly drawn from the Danish population is conducted. We find that deciding for others reduces loss aversion. When choosing between risky prospects...... when losses loom. This finding is consistent with an interpretation of loss aversion as a bias in decision making driven by emotions and that these emotions are reduced when making decisions for others....... for which losses are ruled out by design, subjects make the same choices for themselves as for others. In contrast, when losses are possible, we find that the two types of choices differ. In particular, we find that subjects who make choices for themselves take less risk than those who decide for others...

The logic is in the ∃ * ∀ * first-order fragment and allows (1) Presburger constraints on existentially quantified variables, (2) difference constraints as well as periodicity constraints on universally quantified indices, and (3) difference constraints on values. In particular, using our logic, one can express constraints on consecutive elements of arrays (e.g. ∀i. 0 ≤ i < n → a[i + 1]...

    A language is factorial if it is closed under taking factors, i.e. contiguous subwords. Every factorial language can be described by an antidictionary, i.e. a minimal set of forbidden factors. We show that the problem of deciding whether a factorial language given by a finite antidictionary is well-quasi-ordered under the factor containment relation can be solved in polynomial time. We also discuss possible ways to extend our solution to permutations and graphs.

    2015-04-01

    Full Text Available The decision to vote and choosing among the candidates is a extremely important one with repercussions on everyday life by determining, in global mode, its quality for the whole society. Therefore the whole process by which the voter decide becomes a central concern. In this paper we intend to locate the determinants of the vote decision in the electoral behavior classical theoretical models developed over time. After doing synthesis of classical schools of thought on electoral behavior we conclude that it has been made a journey through the mind, soul and cheek, as follows: the mind as reason in theory developed by Downs, soul as preferably for an actor in Campbell's theory, etc. and cheek as an expression of the impossibility of detachment from social groups to which we belong in Lazarsfeld's theory.

    2012-01-01

    In this paper we present two communication protocols on computing edit distance. In our first result, we give a one-way protocol for the following Document Exchange problem. Namely given x ∈ Σn to Alice and y ∈ Σn to Bob and integer k to both, Alice sends a message to Bob so that he learns x...... or truthfully reports that the edit distance between x and y is greater than k. For this problem, we give a randomized protocol in which Alice transmits at most O ˜ (klog 2 n) bits and each party’s time complexity is O ˜ (nlogn+k 2 log 2 n) . Our second result is a simultaneous protocol for edit distance over...... permutations. Here Alice and Bob both send a message to a third party (the referee) who does not have access to the input strings. Given the messages, the referee decides if the edit distance between x and y is at most k or not. For this problem we give a protocol in which Alice and Bob run a O...

    Earthquake Data Enhanced Cyber-Infrastructure for Disaster Evaluation and Response (E-DECIDER) is a NASA-funded project developing capabilities for decision-making utilizing remote sensing data and modeling software in order to provide decision support for earthquake disaster management and response. E-DECIDER incorporates earthquake forecasting methodology and geophysical modeling tools developed through NASA's QuakeSim project in order to produce standards-compliant map data products to aid in decision-making following an earthquake. Remote sensing and geodetic data, in conjunction with modeling and forecasting tools, help provide both long-term planning information for disaster management decision makers as well as short-term information following earthquake events (i.e. identifying areas where the greatest deformation and damage has occurred and emergency services may need to be focused). E-DECIDER utilizes a service-based GIS model for its cyber-infrastructure in order to produce standards-compliant products for different user types with multiple service protocols (such as KML, WMS, WFS, and WCS). The goal is to make complex GIS processing and domain-specific analysis tools more accessible to general users through software services as well as provide system sustainability through infrastructure services. The system comprises several components, which include: a GeoServer for thematic mapping and data distribution, a geospatial database for storage and spatial analysis, web service APIs, including simple-to-use REST APIs for complex GIS functionalities, and geoprocessing tools including python scripts to produce standards-compliant data products. These are then served to the E-DECIDER decision support gateway (http://e-decider.org), the E-DECIDER mobile interface, and to the Department of Homeland Security decision support middleware UICDS (Unified Incident Command and Decision Support). The E-DECIDER decision support gateway features a web interface that

  17. Pharmacy career deciding: making choice a "good fit".

    Science.gov (United States)

    Willis, Sarah Caroline; Shann, Phillip; Hassell, Karen

    2009-01-01

    The purpose of this article is to explore factors influencing career deciding amongst pharmacy students and graduates in the U.K. Group interviews were used to devise a topic guide for five subsequent focus groups with pharmacy students and graduates. Focus groups were tape-recorded, recordings transcribed, and transcripts analysed. Key themes and interlinking factors relating to pharmacy career deciding were identified in the transcripts, following a constructivist approach. Participants' described making a "good fit" between themselves, their experiences, social networks etc. and pharmacy. Central to a coherent career deciding narrative were: having a job on graduation; and the instrumental advantage of studying a vocational course. Focusing on career deciding of UK pharmacy students and graduates may limit the study's generalisability to other countries. However, our findings are relevant to those interested in understanding students' motivations for healthcare careers, since our results suggest that making a "good fit" describes a general process of matching between a healthcare career and personal experience. As we have found that pharmacy career deciding was not, usually, a planned activity, career advisors and those involved in higher education recruitment should take into account the roles played by personal preferences and values in choosing a degree course. A qualitative study like this can illustrate how career deciding occurs and provide insight into the process from a student's perspective. This can help inform guidance processes, selection to healthcare professions courses within the higher education sector, and stimulate debate amongst those involved with recruitment of healthcare workers about desirable motivators for healthcare careers.

  20. Who Should Decide How Machines Make Morally Laden Decisions?

    2017-08-01

    Who should decide how a machine will decide what to do when it is driving a car, performing a medical procedure, or, more generally, when it is facing any kind of morally laden decision? More and more, machines are making complex decisions with a considerable level of autonomy. We should be much more preoccupied by this problem than we currently are. After a series of preliminary remarks, this paper will go over four possible answers to the question raised above. First, we may claim that it is the maker of a machine that gets to decide how it will behave in morally laden scenarios. Second, we may claim that the users of a machine should decide. Third, that decision may have to be made collectively or, fourth, by other machines built for this special purpose. The paper argues that each of these approaches suffers from its own shortcomings, and it concludes by showing, among other things, which approaches should be emphasized for different types of machines, situations, and/or morally laden decisions.

  1. System of marketing deciding support based on game theory

    2008-12-01

    Full Text Available Quantitative methods and models can be applied in numerous spheres of marketing deciding. The choice of optimal strategy in product advertising is one of the problems that the marketing-management often meets. The use of models developed within the framework of game theory makes significantly easier to find out the solutions of conflict situations that appear herewith. The system of deciding support presented in this work is based on the supposition that two opposed sides take part in the game. With the aim of deciding process promotion, the starting model incorporates computer simulation of percentile changes in the market share that represent elements of payment matrix. The supposition is that the random variables that represent them follow the normal division. It is necessary to carry out the evaluation of their parameters because of relevant data. Information techniques, computer and the adequate program applications take the special position in solving and analysis of the suggested model. This kind of their application represents the basic characteristic of the deciding support system.

  4. On Decidable Growth-Rate Properties of Imperative Programs

    Directory of Open Access Journals (Sweden)

    Amir M. Ben-Amram

    2010-05-01

    Full Text Available In 2008, Ben-Amram, Jones and Kristiansen showed that for a simple "core" programming language - an imperative language with bounded loops, and arithmetics limited to addition and multiplication - it was possible to decide precisely whether a program had certain growth-rate properties, namely polynomial (or linear bounds on computed values, or on the running time. This work emphasized the role of the core language in mitigating the notorious undecidability of program properties, so that one deals with decidable problems. A natural and intriguing problem was whether more elements can be added to the core language, improving its utility, while keeping the growth-rate properties decidable. In particular, the method presented could not handle a command that resets a variable to zero. This paper shows how to handle resets. The analysis is given in a logical style (proof rules, and its complexity is shown to be PSPACE-complete (in contrast, without resets, the problem was PTIME. The analysis algorithm evolved from the previous solution in an interesting way: focus was shifted from proving a bound to disproving it, and the algorithm works top-down rather than bottom-up.

    Angelidis, T.D.

    1977-01-01

    In the light of Heisenberg's interpretation of the uncertainty formulas, the conditions necessary for the derivation of the quantitative statement or law of momentum conservation are considered. The result of such considerations is a contradiction between the formalism of quantum physics and the asserted consequences of Heisenberg's interpretation. This contradiction decides against Heisenberg's interpretation of the uncertainty formulas on upholding that the formalism of quantum physics is both consistent and complete, at least insofar as the statement of momentum conservation can be proved within this formalism. A few comments are also included on Bohr's complementarity interpretation of the formalism of quantum physics. A suggestion, based on a statistical mode of empirical testing of the uncertainty formulas, does not give rise to any such contradiction

    The meeting addressed the question how it is possible to make decision processes and risk assessment for deep repository development more transparent. The two dominant decision approaches used in Sweden and the UK, review/decide(r/d) and inquiry/decide(i/d), were discussed. The main conclusions from group discussions were: It was acknowledged that the concept of transparency includes three equally important aspects: factual issues, value issues, and stake holder's authenticity. There is a need in both countries to bring in the best aspects of both the r/d and the i/d approaches. Both approaches seem to offer possibilities and suffer limitations with respect to the segregation of facts, uncertainties and value judgements, and some sort of combination of the two may present a valuable development. However, neither the i/d nor the r/d approach seems to provide a good framework for clarification of the value issue. Experts have dominated the decision process in both countries. There is a need for a more genuine consultation process. The Swedish EIA is evolving in this direction. The regulator should take part in the process, also at an early stage. It is important that the integrity of the regulator is maintained. Rules and responsibilities of implementers, regulators, planning authorities and other decision-makers should be established early in the process. The public should know that they have access to a process that clarifies value judgements, facts, uncertainties and questions. It is necessary for the public to know what the technical issues are, and to have the means to evaluate the authenticity of the experts.

[Italian] I sistemi di supporto alle decisioni che fanno uso di tecniche di analisi multicriterio sono strumenti che, adattandosi ai vari problemi, affiancano il decisore senza sostituirlo, assistendolo nella formulazione del problema, suggerendo e confrontando soluzioni alternative, scartando quelle inefficienti. per valutare la scelta tra due ipotesi alternative di gestione dei rifiuti solidi urbani e' stato applicato al caso di Trento un modello di supporto alle decisioni denominato AHP (Analytic Hierarchy Process), ampiamente utilizzato nella valutazione del ciclo di vita dei prodotti (LCA). Il metodo consente di evidenziare la soluzione che, tra piu' alternative rispetta maggiormente la scala di priorita' definita dal decisore, mantenendo quindi la maggior coerenza possibile tra le premesse e gli obiettivi. Il modello ha messo a confronto due sistemi integrati di smaltimento dei rifiuti per il Trentino. Una soluzione basata sullo schema del Piano Provinciale di smaltimento dei rifiuti del 1997 in cui la discarica ha ancora un ruolo di primo ordine, ed una soluzione alternativa che attribuisce un ruolo centrale alla termodistruzione. Ilmodello ha integrato contemporaneamente tutti gli indicatori (economici, ambientali, energetici e prestazionali), e ha consentito di identificare come soluzione migliore, l'ipotesi alternativa. I vantaggi ambientali, energetici e di prestazione (maggiore recupero di energia e materiali, maggiore autonomia di smaltimento garantita dal sistema e minore impatto tossicologico) conseguibili con la seconda ipotesi, opportunamente pesati, possono orientare il decisore verso una scelta non dettata da sole motivazioni di ordine economico, ma che tenga conto delle esternalita' incluse nella valutazione.

    The National Institute of Clinical Excellence states that bariatric surgery may be considered for adolescents with severe obesity in 'exceptional circumstances'. However, it is not clear what is deemed to be exceptional, and there is a lack of long-term outcomes data or research, which would inform patient selection. This is an in-depth qualitative study involving five adolescents who had previously undergone bariatric surgery (between 1 and 3 years postoperatively) and four who were being assessed for the treatment. All patients were from one tertiary NHS weight management service offering bariatric surgery to adolescents. Participants were interviewed to explore how young people decide whether bariatric surgery is an appropriate intervention for them. Of the nine adolescents recruited, four were male and five female, aged between 17 and 20 years at the time of interview. Participants who had already undergone surgery did so between the ages of 16 and 18. The data were analysed using interpretative phenomenological analysis, and key themes were identified, such as (i) wanting a different future, (ii) experiences of uncertainty, (iii) managing the dilemmas and (iv) surgery as the last resort. The findings suggest that young people are prepared to accept a surgical solution for obesity despite numerous dilemmas. Young people choose this intervention as a way of 'normalizing' when they perceive there is nothing better available. It is argued that these findings may have implications for the counselling of young people living with overweight and obesity and for government policy. © 2018 World Obesity Federation.

  13. Consent and assessment of capacity to decide or refuse treatment.

    Science.gov (United States)

    Simpson, Owena

    Consent protects the right of patients to decide what happens to them. Before any medical intervention, adults must give valid consent, which must be voluntary, informed and given free of undue influence. When consent is being obtained, patients must be informed about the intervention, why it is being done and its risks; information they are given must be recorded. Every effort should be made to explain the issues in terms that the patient can understand and by providing support and aids to communicate. Consent can be expressed, where patients say they consent or put it in writing, or implied, where a healthcare professional infers from their behaviour that they consent. While different types of consent are valid, some are evidence of stronger proof in court that valid consent has been given. Competent adults have the right to refuse treatment, regardless of the reasons they give for refusal and even if the refusal will result in death; clinicians must respect their decision. In some circumstances-such as when an unconscious person is admitted as an emergency-healthcare professionals can make decisions on behalf of patients, and must do so in patients' best interests.

  14. When we decided to create the Revista Scientific

    Full Text Available When we proposed to create the Revista Scientific, we had many doubts about what would be the treatment to be followed for the development of it? On the one hand, we needed to create a common basis for their more ethical and moral aspects so that the authors always applied the same criteria. This is not only to achieve an editorial unit, but to establish guidelines to follow throughout the publication, so as to facilitate the reading and understanding of the contents from the respect to the information, to the sources, but on all to the readers. The rules created are, therefore, the guidelines to be followed by the authors that appear in our publication, which must take into account these basic rules. Another point to be addressed was the selection of a disciplinary and multidisciplinary team at the international level that is in charge of the valuation of scientific productions, high invoice equipment of different Universities and Organizations recognized worldwide. On the basis of the above considerations, the question arises of deciding, what can or should be, and what can not or should not be counted, but rather how to explain and explain information in the most ethically correct way from the deontological perspective of the writer. It should be noted that Scientific tries to serve as a complement and informative tool for both teachers and the general public. We aim to disseminate scientific and technological knowledge, through the original results, the product of scientific research, which represent a contribution to the development of science and technology. It includes works, products of scientific research and theoretical reflections that, due to their relevance, merit publication, and in this way contribute to the visibility of intellectual production in the areas of education and social sciences. Scientific Magazine is aimed at the academic audience in its different levels (Initial, Basic, University as well as the scientific community

    Full Text Available In 2004, the Province of Córdoba, Argentina implemented lay participation in criminal decisions by means of Law 9182. The law was passed within a context of national debate concerning efficient measures to fight against insecurity and crime. These debates were brought about by a social movement led by Juan Carlos Blumberg, which demanded harsher penalties and judicial reform as means to improve urban safety.Data obtained in two public opinions studies, conducted in 1993 and 2011, are used to analyze trends in attitudes towards criminal punishment, including issues such as the image of criminals or opinions on capital punishment. The revision also includes the influence of the fear of crime on attitudes towards punishment.The analysis of citizen views on punishment extends beyond public opinion data to the judicial field, reviewing how these views are expressed during jury service. Using a set of 213 sentences decided between 2005 and 2012, juror and judge decisions on the same cases are compared.

    In this work the stabilization of hazardous solid wastes containing heavy metals has been studied by means of novel matrices able to generate calcium trisulphoaluminate and silicate hydrates. The process is based on the hydration of two different mixtures containing blast furnace slag, coal ashes, chemical gypsum and Portland cement. The stabilization capacity of the two mixtures has been checked with regard to both a residue from an incinerator of municipal solid wastes and model systems obtained by adding 5 and 10% of soluble nitrates of Cd, Cr, Cu, Ni, Pb and Zn. The stabilized products have been validated from the point of view of mechanical properties by determining the unconfined compressive strength, and from the environmental point of view by means of static and dynamic leaching tests. Both matrices have proved to have great potentiality for the stabilization of hazardous solid wastes, the one based on blast furnace slag being better. Finally, evidence is given that different leaching tests are necessary to fully understand the immobilization mechanism responsible for stabilization. [Italiano] In questo lavoro e` stata studiata la atbilizzazione di residui tossici e nocivi contenenti metalli pesanti per mezzo di matrici leganti innovative capaci di generare trisolfoalluminato e silicato di calcio idrati.

Le capacita` stabilizzanti delle due miscele sono state verificate sia nei confronti di un residuo solido generato a seguito dell`incenerimento di RSU, che nei confronti di sistemi modello ottenuti aggiungendo singolarmente il 5 e 10% dei nitrati solubili di Cd, Cr, Cu, Ni, Pb e Zn. I prodotti solidi stabilizzati sono stati validati dal punto di vista delle prestazioni meccaniche mediante prove di resistenza a compressione, e dal punto di vista ambientale mediante test di rilascio sia statici che dinamici

    We describe the rationale, development, and usability testing for an integrated e-learning tool and decision aid for parents facing decisions about genome-wide sequencing (GWS) for their children with a suspected genetic condition. The online tool, DECIDE, is designed to provide decision-support and to promote high quality decisions about undergoing GWS with or without return of optional incidental finding results. DECIDE works by integrating educational material with decision aids. Users may tailor their learning by controlling both the amount of information and its format - text and diagrams and/or short videos. The decision aid guides users to weigh the importance of various relevant factors in their own lives and circumstances. After considering the pros and cons of GWS and return of incidental findings, DECIDE summarizes the user's responses and apparent preferred choices. In a usability study of 16 parents who had already chosen GWS after conventional genetic counselling, all participants found DECIDE to be helpful. Many would have been satisfied to use it alone to guide their GWS decisions, but most would prefer to have the option of consulting a health care professional as well to aid their decision. Further testing is necessary to establish the effectiveness of using DECIDE as an adjunct to or instead of conventional pre-test genetic counselling for clinical genome-wide sequencing.

    Much of the damage to health caused by drugs could be prevented by appropriate care. A well-defined duty of care and further information are required for healthcare professionals. Although there are many litigation cases to use as references, neither the extent of the duty of care nor the obligation to explain medication according to the type of drug prescribed has yet been fully established. Thus, we systematically collected decided cases of adverse drug events, and assessed the degree of the duties of care and information. Specifically, we collected decided cases in which physicians, dentists, pharmacists, nurses, or hospitals had been sued. Data were derived from Bessatsu Jurist Iryo-kago Hanrei Hyakusen, Hanrei Jihou, and Hanrei Times from 1989 to November 2013, and information on precedents in the records of the Supreme Court of Japan from 2001 to November 2013. We analyzed the cases, and assessed the following according to the type of drug: (1) standards and explanations when dealing with drugs that were critical issues in litigation, and (2) the degree of the physician's or pharmacist's duties of care and information. In total, 126 cases were collected. The number of drug categories classified was 27, and 9 were considered of practical importance. After this systematic review, we found a trend in the degree of the required level of care and information on several drugs. With respect to duties of care and information, the gap between the required level and actual practice suggests that healthcare professionals must improve their care and explanations.

    E-DECIDER initiated rapid response mode when the California Earthquake Clearinghouse was activated the morning following the M6 Napa earthquake. Data products, including: 1) rapid damage and loss estimates, 2) deformation magnitude and slope change maps, and 3) aftershock forecasts were provided to the Clearinghouse partners within 24 hours of the event via XchangeCore Web Service Data Orchestration sharing. NASA data products were provided to end-users via XchangeCore, EERI and Clearinghouse websites, and ArcGIS online for Napa response, reaching a wide response audience. The E-DECIDER team helped facilitate rapid delivery of NASA products to stakeholders and participated in Clearinghouse Napa earthquake briefings to update stakeholders on product information. Rapid response products from E-DECIDER can be used to help prioritize response efforts shortly after the event has occurred. InLET (Internet Loss Estimation Tool) post-event damage and casualty estimates were generated quickly after the Napa earthquake. InLET provides immediate post-event estimates of casualties and building damage by performing loss/impact simulations using USGS ground motion data and FEMA HAZUS damage estimation technology. These results were provided to E-DECIDER by their collaborators, ImageCat, Inc. and the Community Stakeholder Network (CSN). Strain magnitude and slope change maps were automatically generated when the Napa earthquake appeared on the USGS feed. These maps provide an early estimate of where the deformation has occurred and where damage may be localized. Using E-DECIDER critical infrastructure overlays with damage estimates, decision makers can direct response effort that can be verified later with field reconnaissance and remote sensing-based observations. Earthquake aftershock forecast maps were produced within hours of the event. These maps highlight areas where aftershocks are likely to occur and can also be coupled with infrastructure overlays to help direct response

    This study explores women's experience of marital therapy while they navigated decision making around divorce. A qualitative method was used to gain a deeper understanding of the participants' therapy and relationship decision-making experiences. How are women's decisions whether or not to exit their marriage affected by therapy? The researchers interviewed 15 women who had considered initiating divorce before they turned 40 and had attended at least five marital therapy sessions but ultimately decided not to divorce. In general, participants reported that the therapy was helpful to them, their decision-making process and their marriages. Five main themes emerged from the interviews: Women Initiated Therapy, Therapist Was Experienced as Unbiased, Therapy was Helpful, Importance of Extra-therapeutic Factors, and Gradual Process. © 2014 American Association for Marriage and Family Therapy.

    2009-07-01

    Based on extensive questionnaire data, this paper focuses on parents' views about children's right to decide about participation in research. The data originates from 4000 families participating in a longitudinal prospective screening as 1997. Although current regulations and recommendations underline that children should have influence over their participation, many parents in this study disagree. Most (66%) were positive providing information to the child about relevant aspects of the study. However, responding parents were split about whether or not children should at some point be allowed decisional authority when participating in research: 41.6% of the parents reported being against or unsure. Those who responded positively believed that children should be allowed to decide about blood-sampling procedures (70%), but to a less extent about participation (48.5%), analyses of samples (19.7%) and biological bank storage (15.4%). That as many as possible should remain in the study, and that children do not have the competence to understand the consequences for research was strongly stressed by respondents who do not think children should have a right to decide. When asked what interests they consider most important in paediatric research, child autonomy and decision-making was ranked lowest. We discuss the implications of these findings.

    The paper describes an Integrate Source Collection System applied to municipal solid waste, through: introduction of source collection methodologies of the organic fraction (FORSU), of the co-mingled recyclable fraction (RDM) and of the no-recyclable fraction (remaining part), realization of structures (transfer station) able to optimize the sorting and the transportation of the different fraction. The main principle followed interprets the differential collection no longer as an additional service (which would mean an increase in cost) but a substitutive service to the normal one (where the increase in cost is compensated by a reduction of cost referent to no-recyclable fraction). The objects of the studied system: increasing of the collection aimed to recover and recycling minimizing managing cost; have been carried out through an experimental application. Moreover the optimization of the collection routes, reached using numerical computing is presented. [Italian] Nel presente lavoro si descrive l'applicazione di un servizio di raccolta integrale dei RSU tramite: l'introduzione delle metodologie di raccolta Umido (Frazione Organica dei Rifiuti Solidi Urbani), Secco Riciclabile (Raccolta Differenziata Multimediale) e Secco Non Riciclabile (Indifferienziato), la realizzazione delle strutture necessarie al suo funzionamento ed alla sua razionalizzazione economica (Stazione di Trasferenza). La metodologia proposta presenta un carattere fortemente innovativo. Il principio generale seguito interpreta la raccolta indifferenziata non piu' come servizio aggiuntivo (quindi con incremento dei costi in funzione dell'incremento dei servizi relativi), ma come sistema sostitutivo al normale servizio (incremento dei costi compensato dalla riduzione dei costi relativi alla frazione indifferenziata sia in temini di smaltimento che di raccolta). Le finalita' del sistema: massimizzare i livelli di intercettazione e recupero delle frazioni riciclabili

This study is methodologically based on the funded theory and symbolic interactionism. The findings show different meanings of reproduction and interpretation of the principles of gender which guide the decisions regarding offspring. When a couple understands reproduction as an end, they decide to prepare themselves and to plan the

    2018-03-01

    Purpose This study was conducted to determine the effect of iCanDecide, an interactive and tailored breast cancer treatment decision tool, on the rate of high-quality patient decisions-both informed and values concordant-regarding locoregional breast cancer treatment and on patient appraisal of decision making. Methods We conducted a randomized clinical trial of newly diagnosed patients with early-stage breast cancer making locoregional treatment decisions. From 22 surgical practices, 537 patients were recruited and randomly assigned online to the iCanDecide interactive and tailored Web site (intervention) or the iCanDecide static Web site (control). Participants completed a baseline survey and were mailed a follow-up survey 4 to 5 weeks after enrollment to assess the primary outcome of a high-quality decision, which consisted of two components, high knowledge and values-concordant treatment, and secondary outcomes (decision preparation, deliberation, and subjective decision quality). Results Patients in the intervention arm had higher odds of making a high-quality decision than did those in the control arm (odds ratio, 2.00; 95% CI, 1.37 to 2.92; P = .0004), which was driven primarily by differences in the rates of high knowledge between groups. The majority of patients in both arms made values-concordant treatment decisions (78.6% in the intervention arm and 81.4% in the control arm). More patients in the intervention arm had high decision preparation (estimate, 0.18; 95% CI, 0.02 to 0.34; P = .027), but there were no significant differences in the other decision appraisal outcomes. The effect of the intervention was similar for women who were leaning strongly toward a treatment option at enrollment compared with those who were not. Conclusion The tailored and interactive iCanDecide Web site, which focused on knowledge building and values clarification, positively affected high-quality decisions largely by improving knowledge compared with static online

  9. How many invariant polynomials are needed to decide local unitary equivalence of qubit states?

    International Nuclear Information System (INIS)

    Maciążek, Tomasz; Oszmaniec, Michał; Sawicki, Adam

    2013-01-01

    Given L-qubit states with the fixed spectra of reduced one-qubit density matrices, we find a formula for the minimal number of invariant polynomials needed for solving local unitary (LU) equivalence problem, that is, problem of deciding if two states can be connected by local unitary operations. Interestingly, this number is not the same for every collection of the spectra. Some spectra require less polynomials to solve LU equivalence problem than others. The result is obtained using geometric methods, i.e., by calculating the dimensions of reduced spaces, stemming from the symplectic reduction procedure

    The aim of the present study was to correlate in vitro properties of drug formulation to its in vivo performance, and to elucidate the deciding properties of oral absorption. Gastrointestinal simulation technology (GST) was used to simulate the in vivo plasma concentration-time curve and was implemented by GastroPlus™ software. Lansoprazole, a typical BCS class II drug, was chosen as a model drug. Firstly, physicochemical and pharmacokinetic parameters of lansoprazole were determined or collected from literature to construct the model. Validation of the developed model was performed by comparison of the predicted and the experimental plasma concentration data. We found that the predicted curve was in a good agreement with the experimental data. Then, parameter sensitivity analysis (PSA) was performed to find the key parameters of oral absorption. The absorption was particularly sensitive to dose, solubility and particle size for lansoprazole enteric-coated tablets. With a single dose of 30 mg and the solubility of 0.04 mg/ml, the absorption was complete. A good absorption could be achieved with lansoprazole particle radius down to about 25 μm. In summary, GST is a useful tool for profiling biopharmaceutical deciding properties of absorption of lansoprazole enteric-coated tablets and guiding the formulation optimization.

    In order to evaluate the usefulness in deciding surgical indication in secondary hyperparathyroidism (SHP), 67 Ga scintigraphy was performed in 37 patients of SHP before parathyroidectomy (PTx). The radionuclide accumulation in skull and submandible was classified into 4 patterns (skull-submandibular pattern, skull pattern, submandibular pattern and normal pattern). Serum alkaline phosphatase levels were significantly elevated in patients of skull-submandibular pattern (13 cases) compared with skull pattern (6 cases), submandibular pattern (6 cases) and normal pattern (12 cases). Serum intact parathyroid hormone levels were significantly elevated in patients of skull-submandibular and skull patterns compared with normal pattern. No significant difference was observed among the weight of resected parathyroid glands. In 4 of 6 patients of normal pattern on 67 Ga scintigram, bone scintigraphy showed a characteristic pattern of SHP including an increased accumulation in the skull and submandible. Bone mineral density (BMD) in the distal radius was increased within six to twelve months after PTx in 10 of 11 patients of skull-submandibular pattern on 67 Ga scintigram, whereas only one patient showed an increase in BMD in 9 patients of normal pattern. In summary, it was concluded that 67 Ga scintigraphy could provide a useful information in deciding the indication for PTx in secondary hyperparathyroidism. (author)

  12. Flowchart Programs, Regular Expressions, and Decidability of Polynomial Growth-Rate

    Directory of Open Access Journals (Sweden)

    Amir M. Ben-Amram

    2016-07-01

    Full Text Available We present a new method for inferring complexity properties for a class of programs in the form of flowcharts annotated with loop information. Specifically, our method can (soundly and completely decide if computed values are polynomially bounded as a function of the input; and similarly for the running time. Such complexity properties are undecidable for a Turing-complete programming language, and a common work-around in program analysis is to settle for sound but incomplete solutions. In contrast, we consider a class of programs that is Turing-incomplete, but strong enough to include several challenges for this kind of analysis. For a related language that has well-structured syntax, similar to Meyer and Ritchie's LOOP programs, the problem has been previously proved to be decidable. The analysis relied on the compositionality of programs, hence the challenge in obtaining similar results for flowchart programs with arbitrary control-flow graphs. Our answer to the challenge is twofold: first, we propose a class of loop-annotated flowcharts, which is more general than the class of flowcharts that directly represent structured programs; secondly, we present a technique to reuse the ideas from the work on tructured programs and apply them to such flowcharts. The technique is inspired by the classic translation of non-deterministic automata to regular expressions, but we obviate the exponential cost of constructing such an expression, obtaining a polynomial-time analysis. These ideas may well be applicable to other analysis problems.

  14. Involving Communities in Deciding What Benefits They Receive in Multinational Research.

    Wendler, David; Shah, Seema

    2015-10-01

    There is wide agreement that communities in lower-income countries should benefit when they participate in multinational research. Debate now focuses on how and to what extent these communities should benefit. This debate has identified compelling reasons to reject the claim that whatever benefits a community agrees to accept are necessarily fair. Yet, those who conduct clinical research may conclude from this rejection that there is no reason to involve communities in the process of deciding how they benefit. Against this possibility, the present manuscript argues that involving host communities in this process helps to promote four important goals: (1) protecting host communities, (2) respecting host communities, (3) promoting transparency, and (4) enhancing social value.

  15. Sufficient and Necessary Condition to Decide Compatibility for a Class of Interorganizational Workflow Nets

    Directory of Open Access Journals (Sweden)

    Guanjun Liu

    2015-01-01

    Full Text Available Interorganizational Workflow nets (IWF-nets can well model many concurrent systems such as web service composition, in which multiple processes interact via sending/receiving messages. Compatibility of IWF-nets is a crucial criterion for the correctness of these systems. It guarantees that a system has no deadlock, livelock, or dead tasks. In our previous work we proved that the compatibility problem is PSPACE-complete for safe IWF-nets. This paper defines a subclass of IWF-nets that can model many cases about interactions. Necessary and sufficient condition is presented to decide their compatibility, and it depends on the net structures only. Finally, an algorithm is developed based on the condition.

  16. Internal audit assurance or consulting services rendered on governance: How does one decide?

    Directory of Open Access Journals (Sweden)

    Naomi Wilkinson

    2015-04-01

    Full Text Available The concept of organisational governance maturity and what exactly this entails is still perceived as somewhat of a mystery to most and, as a result, internal auditing find themselves in a dilemma when deciding which services to deliver in this regard. The objective of this article was to develop an organisational governance maturity framework that could be used as a measurement tool to assist internal auditing in this dilemma. A preliminary organisational governance maturity framework was developed based on the most relevant literature. A case study was conducted to obtain feedback on the preliminary framework from key stakeholders in the organisation. The results indicated that the framework significantly contributed to the determining and continuous monitoring of governance maturity; both for management and internal auditing.

    Full Text Available An entrepreneur has to follow several steps when deciding to start a new business. Starting a business involves planning, making key financial decisions, completing a series of legal activities, hiring reliable employees and after all of this the success of the new firm is determined by a few steps, which every manager must take into account. One of these steps is adopting a company name, the calling card of the business, taking into consideration the related tips regarding its selection. Entrepreneur must estimate the initial investment and the necessary financial resources. When talking about a company its mission must be clear and easy to understand. Thus, the description of the main activity and the general environment must be present in the business plan as well.

  18. PSI decides to write off most of its $2.7B Marble Hill investment

    1986-01-01

    After the Indiana Supreme Court ruled last November that the utility may not recover its investment from the cancelled plant, Public Service Indiana (PSI) decided to write off a substantial portion of the $2.7 million already invested in the cancelled Marble Hill nuclear plant. The board will omit common stock dividends for three years and the preferred stock dividend for the first quarter. It will also accept a negotiated rate settlement of 8.2% increase. A 5% emergency surcharge will become permanent. The settlement calls for the utility to restrict capital expenditures over the next three years to the $285.1 million already budgeted for construction. Opposition from a consumers group argues that ratepayers should not be the risk bearers for PSI, but the utility argues that its long-term financial health depends on attracting and keeping investors

    Full Text Available Decompressive craniectomy (DC following brain injury can induce complications (hemorrhage, infection, and hygroma. It is then considered as a last-tier therapy, and can be deleteriously delayed. Focal neuromonitoring (microdialysis and PtiO2 can help clinicians to decide bedside to perform DC in case of intracranial pressure (ICP around 20 to 25 mmHg despite maximal medical treatment. This was the case of a hunter, brain injured by gunshot. DC was performed at day 6, because of unstable ICP, ischemic trend of PtiO2, and decreased cerebral glucose but normal lactate/pyruvate ratio. His evolution was good despite left hemiplegia due to initial injury.

    Full Text Available Jacob M. Nolan gives a timely examination of the case of R (on the application of Miller and Dos Santos v Secretary of State for Exiting the European Union – arguably amongst the most important cases on constitutional law decided by the UK Supreme Court. In this landmark case the Supreme Court was required to rule on whether the UK Government (the executive could trigger Article 50 of the Treaty on European Union without the authorisation of an Act of Parliament, through the use of the Crown’s prerogative. On an 8 – 3 majority, with Lords Reed, Carnwath, and Hughes dissenting, the Supreme Court upheld the previous High Court ruling that an Act of Parliament was first required.

  1. Consideration on risk of drinking water. How was the regulation value in water decided?

    International Nuclear Information System (INIS)

    Murakami Michio

    2011-01-01

    This is an explanatory lecture record of the title subject, motivated by detection of radioactivity in tap water of Tokyo (I-131, 30 Bq/kg) in March 2011. The author explains the process of the detection in comparison with radioactivity in the vegetables and Fukushima spinach, and refers with temporary regulation values (March to April) of Cs-134, 137, U and Pu/transuranium elements as well as I-131 in drinking water and other foods. Also commented is that even water with satisfactorily less than the standard value cannot be said to be absolutely safe. Japan generally decides the standard value based on World Health Organization (WHO) guideline which assumes no threshold for radiation carcinogenesis. Relationship between low dose exposure in Hiroshima and carcinogenesis is obscure, of which situation is also similar in Chinese Guangdon where natural dose is always higher than other areas of the world. The regulation values above are derived from the index values decided by Nuclear Safety Committee of Japan (NSCJ) and Codex committee founded by FAO and WHO, and used at emergency, not at ordinary. Then explained are concept for calculation of regulation values, actual calculating equations of the value for water according to WHO, Codex and NSCJ, and of index values of I-131 and Cs by NSCJ. Exposure dose by I-131 in water and food in Tokyo is actually estimated in this paper to consider its risk (carcinogenic, 0.3/100 thousands people/year) by comparison with other matters like arsenic exposure (1.3) and traffic accident (deaths, 4.5). Lastly, the author warns with Sedgwick's words that Standards are devices to keep the lazy mind from thinking. (T.T.)

    2013-01-01

    Although there is evidence to tracking progress towards facility births within the UN Millennium Development Goals framework, we do not know whether women are deciding against home birth over their reproductive lives. Using Demographic and Health Surveys (DHS) data from 44 countries, this study aims to investigate the patterns and shifts in childbirth locations and to determine whether these shifts are in favour of home or health settings. The analyses considered 108,777 women who had at least two births in the five years preceding the most recent DHS over the period 2000-2010. The vast majority of women opted for the same place of childbirth for their successive births. However, about 14% did switch their place and not all these decisions favoured health facility over home setting. In 24 of the 44 countries analysed, a higher proportion of women switched from a health facility to home. Multilevel regression analyses show significantly higher odds of switching from home to a facility for high parity women, those with frequent antenatal visits and more wealth. However, in countries with high infant mortality rates, low parity women had an increased probability of switching from home to a health facility. There is clear evidence that women do change their childbirth locations over successive births in low and middle income countries. After two decades of efforts to improve maternal health, it might be expected that a higher proportion of women will be deciding against home births in favour of facility births. The results from this analysis show that is not the case.

  5. How US institutional review boards decide when researchers need to translate studies.

    2014-03-01

    Informed consent is crucial in research, but potential participants may not all speak the same language, posing questions that have not been examined concerning decisions by institutional review boards (IRBs) and research ethics committees' (RECs) about the need for researchers to translate consent forms and other study materials. Sixty US IRBs (every fourth one in the list of the top 240 institutions by The National Institutes of Health funding) were contacted, and leaders (eg, chairs) from 34 (response rate=57%) and an additional 12 members and administrators were interviewed. IRBs face a range of problems about translation of informed consent documents, questionnaires and manuals-what, when and how to translate (eg, for how many or what proportion of potential subjects), why to do so and how to decide. Difficulties can arise about translation of specific words and of broader cultural concepts regarding processes of informed consent and research, especially in the developing world. In these decisions, IRBs weigh the need for autonomy (through informed consent) and justice (to ensure fair distribution of benefits and burdens of research) against practical concerns about costs to researchers. At times IRBs may have to compromise between these competing goals. These data, the first to examine when and how IRBs/RECs require researchers to translate materials, thus highlight a range of problems with which these committees struggle, suggesting a need for further normative and empirical investigation of these domains, and consideration of guidelines to help IRBs deal with these tensions.

  6. Slime moulds use heuristics based on within-patch experience to decide when to leave.

    2015-04-15

    Animals foraging in patchy, non-renewing or slowly renewing environments must make decisions about how long to remain within a patch. Organisms can use heuristics ('rules of thumb') based on available information to decide when to leave the patch. Here, we investigated proximate patch-departure heuristics in two species of giant, brainless amoeba: the slime moulds Didymium bahiense and Physarum polycephalum. We explicitly tested the importance of information obtained through experience by eliminating chemosensory cues of patch quality. In P. polycephalum, patch departure was influenced by the consumption of high, and to a much lesser extent low, quality food items such that engulfing a food item increased patch-residency time. Physarum polycephalum also tended to forage for longer in darkened, 'safe' patches. In D. bahiense, engulfment of any food item increased patch residency irrespective of that food item's quality. Exposure to light had no effect on the patch-residency time of D. bahiense. Given that these organisms lack a brain, our results illustrate how the use of simple heuristics can give the impression that individuals make sophisticated foraging decisions. © 2015.

    The recent war on terrorism and increased urban warfare has been a major catalysis for increased interest in the development of disposable unattended wireless ground sensors. While the application of these sensors to hostile domains has been generally governed by specific tasks, this research explores a unique paradigm capitalizing on the fundamental functionality related to sensor systems. This functionality includes a sensors ability to Sense - multi-modal sensing of environmental events, Decide - smart analysis of sensor data, Act - response to environmental events, and Communication - internal to system and external to humans (SDAC). The main concept behind SDAC sensor systems is to integrate the hardware, software, and networking to generate 'knowledge and not just data'. This research explores the usage of wireless SDAC units to collectively make up a sensor system capable of persistent, adaptive, and autonomous behavior. These systems are base on the evaluation of scenarios and existing systems covering various domains. This paper presents a promising view of sensor network characteristics, which will eventually yield smart (intelligent collectives) network arrays of SDAC sensing units generally applicable to multiple related domains. This paper will also discuss and evaluate the demonstration system developed to test the concepts related to SDAC systems.

    Adolescents with anorexia nervosa rarely present themselves as having a problem and are usually reliant on parents to recognise the problem and facilitate help-seeking. This study aimed to investigate parents' experiences of recognising that their child had an eating problem and deciding to seek help. A qualitative study with interpretative phenomenological analysis applied to semi-structured interviews with eight parents of adolescents with a diagnosis of anorexia nervosa. Parents commonly attributed early signs of anorexia nervosa to normal adolescent development and they expected weight loss to be short-lived. As parents' suspicions grew, close monitoring exposing their child's secretive attempts to lose weight and the use of internet searches aided parental recognition of the problem. They avoided using the term anorexia as it made the problem seem 'real'. Following serial unsuccessful attempts to effect change, parental fear for their child's life triggered a desire for professional help. Parents require early advice and support to confirm their suspicions that their child might have anorexia nervosa. Since parents commonly approach the internet for guidance, improving awareness of useful and accurate websites could reduce delays in help-seeking.

  9. Deciding on gender in children with intersex conditions: considerations and controversies.

    2005-01-01

    Biologic factors such as genetic and hormonal influences contribute to gender identity, gender role behavior, and sexual orientation in humans, but this relationship is considerably modified by psychologic, social, and cultural factors. The recognition of biologically determined conditions leading to incongruity of genetically determined sex, somatic phenotype, and gender identity has led to growing interest in gender role development and gender identity in individuals with intersex conditions. Sex assignment of children with ambiguous genitalia remains a difficult decision for the families involved and subject to controversial discussion among professionals and self-help groups. Although systematic empirical data on outcomes of functioning and health-related quality of life are sparse, anecdotal evidence from case series and individual patients about their experiences in healthcare suggests traumatic experiences in some. This article reviews the earlier 'optimal gender policy' as well as the more recent 'full consent policy' and reviews published data on both surgical and psychosocial outcomes. The professional debate on deciding on sex assignment in children with intersex conditions is embedded in a much wider public discourse on gender as a social construction. Given that the empirical basis of our knowledge of the causes, treatment options, long-term outcomes, and patient preferences is insufficient, we suggest preliminary recommendations based on clinical experience, study of the literature, and interviews with affected individuals.

    This paper describes a technical procedure to assess a software based leak detection system (LDS), by deciding between a simpler low cost, less effective product, having a fast installation and tuning, and a complex one with high cost and efficiency, which however takes a long time to be properly installed. This is a common decision among the pipeline operating companies, considering that the majority of the lines are short, with single phase liquid flow (which may include batches), basic communication system and instrumentation. Service companies offer realistic solutions for liquid flow, but usually designed to big pipeline networks, flowing multiple batches and allowing multiple fluid entrances and deliveries. Those solutions are sometimes impractical to short pipelines, due to its high cost, as well as long tuning procedures, complex instrumentation, communication and computer requirements. It is intended to approach here the best solution according to its cost. In a practical sense, it means to differentiate the various LDS techniques. Those techniques are available in a considerable number, and they are still spreading, according to the different scenarios. However, two most known and worldwide implemented techniques hold the majority of the market: the Compensated Volume Balance (CVB), which is less accurate, reliable and robust, but cheaper, simpler and faster to install, and the Real Time Transient Model (RTTM), which is very reliable, accurate and robust, but expensive and complex. This work will describe a way to define whether one can use or not a CVB in a pipeline. (author)

  11. Function of One Regular Separable Relation Set Decided for the Minimal Covering in Multiple Valued Logic

    2016-01-01

    Full Text Available Multiple-valued logic is an important branch of the computer science and technology. Multiple-valued logic studies the theory, multiple-valued circuit & multiple-valued system, and the applications of multiple-valued logic included.In the theory of multiple-valued logic, one primary and important problem is the completeness of function sets, which can be solved depending on the decision for all the precomplete sets(also called maximal closed sets of K-valued function sets noted by PK*, and another is the decision for Sheffer function, which can be totally solved by picking out all of the minimal covering of the precomplete sets. In the function structure theory of multi-logic, decision on Sheffer function is an important role. It contains structure and decision of full multi-logic and partial multi-logic. Its decision is closely related to decision of completeness of function which can be done by deciding the minimal covering of full multi-logic and partial-logic. By theory of completeness of partial multi-logic, we prove that function of one regular separable relation is not minimal covering of PK* under the condition of m = 2, σ = e.

  12. Application towards the Concept of Rechtsvinding and Rechtsschepping by the Judges in Deciding a Case

    Full Text Available The judge may not refuse to examine and to decide a case which has been submitted to the court despite having unclear or non-existent legal pretext. The judge are expected to be able to explore values and sense of justice that grows and embodies the community as the living law. The concept of justice here is not the outcome by the human intellectualism, but rather from his/her own spirit. A justice could not exist or be born from a mere theory, because justice is naturally born from the deepest conscience of a judge who is also a human being. A person’s conscience can not come in sudden, but was born through the process, practice or habit. Either legal finding (Rechtsvinding or the creation of law (rechtsschepping should be used in providing justice for litigants as follows: First, in absence of the relevant rules within the existing legislation. Second, regulated by the law but insufficiently clear and contain multi-interpretations. Third, regulated by the law but no longer meet the public sense of justice (out of date. Fourth, based on a jurisprudence or an expert opinion.

  13. Rational Probabilistic Deciders—Part I: Individual Behavior

    Directory of Open Access Journals (Sweden)

    S. M. Meerkov

    2007-04-01

    Full Text Available This paper is intended to model a decision maker as a rational probabilistic decider (RPD and to investigate its behavior in stationary and symmetric Markov switch environments. RPDs take their decisions based on penalty functions defined by the environment. The quality of decision making depends on a parameter referred to as level of rationality. The dynamic behavior of RPDs is described by an ergodic Markov chain. Two classes of RPDs are considered—local and global. The former take their decisions based on the penalty in the current state while the latter consider all states. It is shown that asymptotically (in time and in the level of rationality both classes behave quite similarly. However, the second largest eigenvalue of Markov transition matrices for global RPDs is smaller than that for local ones, indicating faster convergence to the optimal state. As an illustration, the behavior of a chief executive officer, modeled as a global RPD, is considered, and it is shown that the company performance may or may not be optimized—depending on the pay structure employed. While the current paper investigates individual RPDs, a companion paper will address collective behavior.

    To discover the reasons for deciding to die in hospital or at home, from the perspective of professionals involved. Qualitative phenomenological study. Intentional sample. Four multidisciplinary focus groups were held, two in hospitals and two in primary care centres in Seville (Spain). Twenty-nine professionals with at least two years experience in the care of people with a terminal disease participated, following the theoretical saturation of information criterion. Responses from the first script were gathered in three core categories: patient and the family, professionals and care process. Patients are generally not asked about their preferences as to where they wish to die, and if their family is not aware of their preference, it is not possible to carry out advanced planning of care. Families tend to choose the hospital because of the possibility of monitoring and resources in primary care. Professionals are trained in how to approach death, but they do not feel sufficiently prepared and focus on the clinical and administrative issues. The care process favours oncology patients because it is easier to identify their illness as terminal. Resources are not equal and interlevel communication needs to be improved. The family's involvement in the process is not facilitated, which impedes their decision-making. Advance care planning and use of the advance directive should be promoted, as well as, interlevel communication and coordination, supply resources, especially in primary care, and professionals should receive training on how to approach death.. The patient's family should be involved in the care process and provided the necessary support. Copyright © 2018 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

  16. Deciding on Science: An Analysis of Higher Education Science Student Major Choice Criteria

    White, Stephen Wilson

    The number of college students choosing to major in science, technology, engineering, and math (STEM) in the United States affects the size and quality of the American workforce (Winters, 2009). The number of graduates in these academic fields has been on the decline in the United States since the 1960s, which, according to Lips and McNeil (2009), has resulted in a diminished ability of the United States to compete in science and engineering on the world stage. The purpose of this research was to learn why students chose a STEM major and determine what decision criteria influenced this decision. According to Ajzen's (1991) theory of planned behavior (TPB), the key components of decision-making can be quantified and used as predictors of behavior. In this study the STEM majors' decision criteria were compared between different institution types (two-year, public four-year, and private four-year), and between demographic groups (age and sex). Career, grade, intrinsic, self-efficacy, and self-determination were reported as motivational factors by a majority of science majors participating in this study. Few students reported being influenced by friends and family when deciding to major in science. Science students overwhelmingly attributed the desire to solve meaningful problems as central to their decision to major in science. A majority of students surveyed credited a teacher for influencing their desire to pursue science as a college major. This new information about the motivational construct of the studied group of science majors can be applied to the previously stated problem of not enough STEM majors in the American higher education system to provide workers required to fill the demand of a globally STEM-competitive United States (National Academy of Sciences, National Academy of Engineering, & Institute of Medicine, 2010).

    To collect information about how people with acne make day-to-day decisions concerning the effectiveness of their treatment. Between May and August 2013, an optional question was embedded in the James Lind Alliance Acne Priority Setting Partnership's online survey to collect treatment uncertainties. The question asked people with acne to "Tell us in your own words how you decide if your treatment has been effective." A total of 742 respondents specified at least one outcome or means of assessing change (outcome measure). Fewer spots were the most commonly cited outcome, identified by 272 respondents (36.7%). Other frequently mentioned outcomes were in descending order: less redness (19.4%), reduction in spot size (12.1%), and less pain/discomfort (11.4%). Signs were much more commonly used than symptoms and surrogate outcomes such as changes in aspects of life quality were infrequently mentioned. Visual inspection of the skin was the most widely adopted outcome measure (16.3%). Although the most frequently used methods map well onto the outcome measures adopted in the majority of acne trials, namely physician-assessed changes in lesion counts and global acne severity, people with acne often take into account several factors that cannot be assessed by a third party at a single point in time. The minimal use of changes in psychosocial wellbeing and mood may reflect that these are regarded as secondary consequences of improvements in appearance. The robustness of these findings now requires independent evaluation. If confirmed, they could form the basis of a new patient-reported outcome measure. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

    Alcohol consumption among university students has reached worrying levels, its effects on driving being highly dangerous. This aspect emphasizes the need to develop prevention programs, intended to raise subjects' awareness about the effects of alcohol on driving. The aim of the present research is to evaluate the effectiveness of the intervention program «Tú decides», implemented at the Algarve University during several students festivals, between 2010-2014. Quasi-experimental study, pre-post test without control group. A total of 5,079 participants were inquired. They were asked, at two different moments, before and after the measurement of the blood alcohol level and giving an information session with technical recommendations to prevent driving under alcohol effects. One factor ANOVA test used, in order to perform a mean comparison, as well as the Chi-square statistics, to perform a proportion comparison (p<.05). It was found that the intention to drive was lower at the second moment (42.1%) (χ(2)=2078.71; p=.000). This intention was influenced by blood alcohol level different levels (χ(2)=338.252; p=.000), gender (χ(2)=35.718; p=.000), age (χ(2)=62.805; p=.000) and professional situation of the participants (χ(2)=27.397; p=.001). We can affirm that the main objective of this intervention was achieved, since the participants followed the technical recommendations based on the blood alcohol level results.

    Falling consent rates for postmortems, regardless of age of death, have been widely reported in recent years. The aim of this study was to explore parental attitudes to, and decision-making about, a perinatal postmortem after termination for fetal abnormality, late miscarriage, or stillbirth. A prospective self-completion questionnaire was given to 35 women and their partners. The participants had experienced second or third trimester pregnancy loss in a single fetal medicine and delivery unit in the United Kingdom and were making decisions about having a postmortem. They were asked to complete a questionnaire about their attitudes to, and expectations of, a perinatal postmortem. Thirty-one questionnaires were received from parents of 17 babies (49% of those asked; 16 from mothers, 15 from fathers). Parents of nine babies (53%) said they would agree to a full postmortem, of three babies to a limited postmortem, and of four babies to an external examination only; one couple were undecided. The most important issues for the parents in this study that related to their decisions about a postmortem centered on the need for information, both for future planning and about what had happened. Moderately important issues related to altruism, which is, improving medical knowledge and helping other parents experiencing similar bereavement. Among the lowest scoring issues were potential barriers, such as concerns about cultural or religious acceptability of a postmortem, funeral delays, and what would happen to the baby's body. Bereaved parents who participated in this study, where postmortem consent rates were relatively high, thought that their need for knowledge eclipsed assumed barriers when deciding whether or not to have a postmortem for their baby. © 2012, Copyright the Authors.

  20. Beyond price: individuals' accounts of deciding to pay for private healthcare treatment in the UK.

    2012-03-07

    Delivering appropriate and affordable healthcare is a concern across the globe. As countries grapple with the issue of delivering healthcare with finite resources and populations continue to age, more health-related care services or treatments may become an optional 'extra' to be purchased privately. It is timely to consider how, and to what extent, the individual can act as both a 'patient' and a 'consumer'. In the UK the majority of healthcare treatments are free at the point of delivery. However, increasingly some healthcare treatments are being made available via the private healthcare market. Drawing from insights from healthcare policy and social sciences, this paper uses the exemplar of private dental implant treatment provision in the UK to examine what factors people considered when deciding whether or not to pay for a costly healthcare treatment for a non-fatal condition. Qualitative interviews with people (n = 27) who considered paying for dental implants treatments in the UK. Data collection and analysis processes followed the principles of the constant comparative methods, and thematic analysis was facilitated through the use of NVivo qualitative data software. Decisions to pay for private healthcare treatments are not simply determined by price. Decisions are mediated by: the perceived 'status' of the healthcare treatment as either functional or aesthetic; how the individual determines and values their 'need' for the treatment; and, the impact the expenditure may have on themselves and others. Choosing a private healthcare provider is sometimes determined simply by personal rapport or extant clinical relationship, or based on the recommendation of others. As private healthcare markets expand to provide more 'non-essential' services, patients need to develop new skills and to be supported in their new role as consumers.

  1. Deciding Where to Burn: Stakeholder Priorities for Prescribed Burning of a Fire-Dependent Ecosystem

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Multiagency partnerships increasingly work cooperatively to plan and implement fire management. The stakeholders that comprise such partnerships differ in their perceptions of the benefits and risks of fire use or nonuse. These differences inform how different stakeholders prioritize sites for burning, constrain prescribed burning, and how they rationalize these priorities and constraints. Using a survey of individuals involved in the planning and implementation of prescribed fire in the Onslow Bight region of North Carolina, we examined how the constraints and priorities for burning in the longleaf pine (Pinus palustris ecosystem differed among three stakeholder groups: prescribed burn practitioners from agencies, practitioners from private companies, and nonpractitioners. Stakeholder groups did not differ in their perceptions of constraints to burning, and development near potentially burned sites was the most important constraint identified. The top criteria used by stakeholders to decide where to burn were the time since a site was last burned, and a site's ecosystem health, with preference given to recently burned sites in good health. Differences among stakeholder groups almost always pertained to perceptions of the nonecological impacts of burning. Prescribed burning priorities of the two groups of practitioners, and particularly practitioners from private companies, tended to be most influenced by nonecological impacts, especially through deprioritization of sites that have not been burned recently or are in the wildland-urban interface (WUI. Our results highlight the difficulty of burning these sites, despite widespread laws in the southeast U.S. that limit liability of prescribed burn practitioners. To avoid ecosystem degradation on sites that are challenging to burn, particularly those in the WUI, conservation partnerships can facilitate demonstration projects involving public and private burn practitioners on those sites.

    Full Text Available Abstract Background Despite high vaccination coverage, there have recently been epidemics of vaccine preventable diseases in the Netherlands, largely confined to an orthodox protestant minority with religious objections to vaccination. The orthodox protestant minority consists of various denominations with either low, intermediate or high vaccination coverage. All orthodox protestant denominations leave the final decision to vaccinate or not up to their individual members. Methods To gain insight into how orthodox protestant parents decide on vaccination, what arguments they use, and the consequences of their decisions, we conducted an in-depth interview study of both vaccinating and non-vaccinating orthodox protestant parents selected via purposeful sampling. The interviews were thematically coded by two analysts using the software program Atlas.ti. The initial coding results were reviewed, discussed, and refined by the analysts until consensus was reached. Emerging concepts were assessed for consistency using the constant comparative method from grounded theory. Results After 27 interviews, data saturation was reached. Based on characteristics of the decision-making process (tradition vs. deliberation and outcome (vaccinate or not, 4 subgroups of parents could be distinguished: traditionally non-vaccinating parents, deliberately non-vaccinating parents, deliberately vaccinating parents, and traditionally vaccinating parents.

    Healthcare decision makers face challenges when using guidelines, including understanding the quality of the evidence or the values and preferences upon which recommendations are made, which are often not clear. GRADE is a systematic approach towards assessing the quality of evidence and the strength of recommendations in healthcare. GRADE also gives advice on how to go from evidence to decisions. It has been developed to address the weaknesses of other grading systems and is now widely used internationally. The Developing and Evaluating Communication Strategies to Support Informed Decisions and Practice Based on Evidence (DECIDE) consortium (http://www.decide-collaboration.eu/), which includes members of the GRADE Working Group and other partners, will explore methods to ensure effective communication of evidence-based recommendations targeted at key stakeholders: healthcare professionals, policymakers, and managers, as well as patients and the general public. Surveys and interviews with guideline producers and other stakeholders will explore how presentation of the evidence could be improved to better meet their information needs. We will collect further stakeholder input from advisory groups, via consultations and user testing; this will be done across a wide range of healthcare systems in Europe, North America, and other countries. Targeted communication strategies will be developed, evaluated in randomized trials, refined, and assessed during the development of real guidelines. Results of the DECIDE project will improve the communication of evidence-based healthcare recommendations. Building on the work of the GRADE Working Group, DECIDE will develop and evaluate methods that address communication needs of guideline users. The project will produce strategies for communicating recommendations that have been rigorously evaluated in diverse settings, and it will support the transfer of research into practice in healthcare systems globally.

    2005-03-01

    On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality

    Stakeholder input is a critical component of comparative effectiveness research. To ensure that the research activities of the Developing Evidence to Inform Decisions about Effectiveness (DEcIDE) Network, supported by the Agency for Healthcare Research and Quality, translate into the greatest impact for everyday practice and policy-making in cancer, we were tasked with soliciting stakeholder input regarding priority areas in cancer-related comparative effectiveness research for the DEcIDE Cancer Consortium. Given the increasing emphasis on stakeholder engagement in research, many investigators are facing a similar task, yet there is limited literature to guide such efforts, particularly in cancer care. To help fill this gap, we present our approach to operationalizing stakeholder engagement and discuss it in the context of other recent developments in the area. We describe challenges encountered in convening stakeholders from multiple vantage points to prioritize topics and strategies used to mitigate these barriers. We offer several recommendations regarding how to best solicit stakeholder input to inform comparative effectiveness research in cancer care. These recommendations can inform other initiatives currently facing the challenges of engaging stakeholders in priority setting for cancer.

  16. Why (and how) they decide to leave: A grounded theory analysis of STEM attrition at a large public research university

    Minutello, Michael F.

    A grounded theory investigation of STEM attrition was conducted that describes and explains why undergraduates at a large Mid-Atlantic research university decided to leave their initial STEM majors to pursue non-STEM courses of study. Participants ultimately decided to leave their initial STEM majors because they were able to locate preferable non-STEM courses of study that did not present the same kinds of obstacles they had encountered in their original STEM majors. Grounded theory data analysis revealed participants initially enrolled in STEM majors with tenuous motivation that did not withstand the various obstacles that were present in introductory STEM coursework. Obstacles that acted as demotivating influences and prompted participants to locate alternative academic pathways include the following: (1.) disengaging curricula; (2.) competitive culture; (3.) disappointing grades; (4.) demanding time commitments; and (5.) unappealing career options. Once discouraged from continuing along their initial STEM pathways, participants then employed various strategies to discover suitable non-STEM majors that would allow them to realize their intrinsic interests and extrinsic goals. Participants were largely satisfied with their decisions to leave STEM and have achieved measures of personal satisfaction and professional success.

    The ability of adult students to reason on the basis of the control of variables was the subject of an extended investigation. This paper describes the part of the study that focused on the reasoning required to decide whether or not a given variable influences the behavior of a system. The participants were undergraduates taking introductory Physics and K-8 teachers studying physics and physical science in inservice institutes and workshops. Although most of the students recognized the need to control variables, many had significant difficulty with the underlying reasoning. The results indicate serious shortcomings in the preparation of future scientists and in the education of a scientifically literate citizenry. There are also strong implications for the professional development of teachers, many of whom are expected to teach control of variables to young students.

  3. How we decide

    Lehrer, Jonah

    2009-01-01

    Since Plato, philosophers have described the decision-making process as either rational or emotional: we carefully deliberate, or we “blink” and go with our gut. But as scientists break open the mind’s black box with the latest tools of neuroscience, they’re discovering that this is not how the mind works. Our best decisions are a finely tuned blend of both feeling and reason—and the precise mix depends on the situation. When buying a house, for example, it’s best to let our unconscious mull over the many variables. But when we’re picking a stock, intuition often leads us astray. The trick is to determine when to use the different parts of the brain, and to do this, we need to think harder (and smarter) about how we think. Jonah Lehrer arms us with the tools we need, drawing on cutting-edge research as well as the real-world experiences of a wide range of “deciders”—from airplane pilots and hedge fund investors to serial killers and poker players. Lehrer shows how people are taking advan...

    2010-03-01

    Full Text Available Abstract Background The management of chiropractic patients with acute and chronic/persistent conditions probably differs. However, little is known on this subject. There is, for example, a dearth of information on maintenance care (MC. Thus it is not known if patients on MC are coerced to partake in a program of frequent treatments over a long period of time, or if they are actively involved in designing their own individualized treatment program. Objectives It was the purpose of this study to investigate how chiropractic patients with low back pain were scheduled for treatment, with special emphasis on MC. The specific research questions were: 1. How many patients are on maintenance care? 2 Are there specific patterns of intervals between treatments for patients and, if so, do they differ between MC patients and non-MC patients? 3. Who decides on the next treatment, the patient, the chiropractor or both, and are there any differences between MC patients and non-MC patients? Methods Chiropractic students, who during their summer holidays were observers in chiropractic clinics in Norway and Denmark, recorded whether patients were classified by the treating chiropractor as a MC-patient or not, dates for last and subsequent visits, and made a judgement on whether the patient or the chiropractor decided on the next appointment. Results Observers in the study were 16 out of 30 available students. They collected data on 868 patients from 15 Danish and 13 Norwegian chiropractors. Twenty-two percent and 26%, respectively, were classified as MC patients. Non-MC patients were most frequently seen within 1 week. For MC patients, the previous visit was most often 2-4 weeks prior to the actual visit, and the next appointment between 1 and 3 months. This indicates a gradual increase in intervals. The decision of the next visit was mainly made by the chiropractor, also for MC patients. However, the study samples of chiropractors appear not to be

  5. A quick and easy test for deciding entanglement status of an N-qubit pure quantum state

    2018-01-01

    We develop a simple criterion in terms of a necessary-sufficient condition (NS condition) for deciding separability of an arbitrary n-qubit pure quantum state. This NS condition provides a quick and easy test procedure to determine the entanglement status of a pure quantum state. We normalize the given quantum state and using this normalized state we can easily build a simplest system of equations containing trigonometric functions by making use of the well known Bloch Sphere representation for single qubit states and check whether or not this system of equations is consistent. According to proposed NS condition the given pure quantum state is separable (entangled) if and only if the above mentioned system of equations is consistent (inconsistent). We build this system of equations by equating the coefficients of computational basis states in the superposition representing the given pure quantum state with certain products of trigonometric functions obtained using standard Bloch Sphere representation for single qubit states. To establish separability of given state one requires to find a valid solution of the above mentioned system of equations but entanglement on the other hand follows when any two equations in this system of equations are mutually inconsistent. Thus, entanglement of the state can follow easily if one succeeds in finding any two mutually inconsistent equations in the above mentioned system of equations.

  6. Deciding to work during the Ebola outbreak: The voices and experiences of nurses and midwives in Liberia

    Full Text Available In this study we explored the experiences of nurses and midwives, including the process involved in deciding whether or not to render care to patients during the Ebola outbreak in Liberia, West Africa. Data were collected from 30 registered nurses and registered midwives through face-to-face, semi-structured, tape-recorded interviews. We combined both Corbin and Strauss (2015 and Charmaz (2014 grounded theory methods of data collection and analysis. The result is a description of the experiences and a conceptual model that describes the social process involved in the work decisions made by the study participants. The core category identified in the data is “living in fear and terror.” The work decisions of nurses and midwives were primarily influenced by family responsibilities and demands. The findings of this study could be applied to education, research, and working policies when planning for future disease outbreaks in Liberia and other regions in the world.

    Domestic violence (DV) perpetrated by men against women is a pervasive global problem with significant physical and emotional consequences. Although some face-to-face interventions in health care settings have shown promise, there are barriers to disclosure to health care practitioners and women may not be ready to access or accept help, reducing uptake. Similar to the mental health field, interventions from clinical practice can be adapted to be delivered by technology. This article outlines the theoretical and conceptual development of I-DECIDE, an online healthy relationship tool and safety decision aid for women experiencing DV. The article explores the use of the Psychosocial Readiness Model (PRM) as a theoretical framework for the intervention and evaluation. This is a theoretical article drawing on current theory and literature around health care and online interventions for DV. The article argues that the Internet as a method of intervention delivery for DV might overcome many of the barriers present in health care settings. Using the PRM as a framework for an online DV intervention may help women on a pathway to safety and well-being for themselves and their children. This hypothesis will be tested in a randomized, controlled trial in 2015/2016. This article highlights the importance of using a theoretical model in intervention development and evaluation.

    Tuncer, C; Canigur Bavbek, N; Balos Tuncer, B; Ayhan Bani, A; Çelik, B

    2015-01-01

    To examine patients' and parents' perceptions and expectations from orthodontic treatment. 491 patients (274 female, 217 male) aged 14-22 years, and 399 parents (245 female, 154 male) completed a questionnaire about preferences, needs and expectations about orthodontic treatment, and scored the present problem. Continuous variables were compared by Mann-Whitney U and Kruskal-Wallis tests, whereas Chi-square test was used for categorical variables. Patients'(77.1%) and parents'(84.6%), decision about orthodontic treatments were influenced by suggestion of dentists. Patients who decided to attend to clinic by themselves were higher than parents (p=0.006). Dental aesthetics was the determinant factor for treatment demand for patients(61.0%) and parents(57.3%). Improvement in oral functions was more important for Class III patients than Class I patients (p=0.040). Adult patients/parents with higher education gave more importance to oral functions as well as dental aesthetics (p=0.031). There was no difference among Angle classifications regarding orthodontic problem scores. Parents found media sources valuable (p=0.018) but majority expected dentists for information about orthodontic treatments. Education degree of adult patients/parents effected this decision(p=0.002). Desire to have better dental aesthetics was the primary motivating factor for all participants. Clinicians should consider concerns of Class III patients about oral functions during treatment planning.

  9. Quality control of Photosystem II: reversible and irreversible protein aggregation decides the fate of Photosystem II under excessive illumination

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available In response to excessive light, the thylakoid membranes of higher plant chloroplasts show dynamic changes including the degradation and reassembly of proteins, a change in the distribution of proteins, and large-scale structural changes such as unstacking of the grana. Here, we examined the aggregation of light-harvesting chlorophyll-protein complexes and Photosystem II core subunits of spinach thylakoid membranes under light stress with 77K chlorophyll fluorescence; aggregation of these proteins was found to proceed with increasing light intensity. Measurement of changes in the fluidity of thylakoid membranes with fluorescence polarization of diphenylhexatriene showed that membrane fluidity increased at a light intensity of 500–1,000 µmol photons m-2 s-1, and decreased at very high light intensity (1,500 µmol photons m-2 s-1. The aggregation of light-harvesting complexes at moderately high light intensity is known to be reversible, while that of Photosystem II core subunits at extremely high light intensity is irreversible. It is likely that the reversibility of protein aggregation is closely related to membrane fluidity: increases in fluidity should stimulate reversible protein aggregation, whereas irreversible protein aggregation might decrease membrane fluidity. When spinach leaves were pre-illuminated with moderately high light intensity, the qE component of non-photochemical quenching and the optimum quantum yield of Photosystem II increased, indicating that Photosystem II/ light-harvesting complexes rearranged in the thylakoid membranes to optimize Photosystem II activity. Transmission electron microscopy revealed that the thylakoids underwent partial unstacking under these light stress conditions. Thus, protein aggregation is involved in thylakoid dynamics and regulates photochemical reactions, thereby deciding the fate of Photosystem II.

    To examine how clinicians practise the principles of beneficence when deciding to allow or deny family presence during resuscitation. Family presence during resuscitation has important benefits for family and is supported by professional bodies and the public. Yet, many clinicians restrict family access to patients during resuscitation, and rationales for decision-making are unclear. Secondary analysis of an existing qualitative data set using deductive category application of content analysis. We analysed 20 interview transcripts from 15 registered nurses, two doctors and three paramedics who had experienced family presence during resuscitation in an Australian hospital. The transcripts were analysed for incidents of beneficent decision-making when allowing or denying family presence during resuscitation. Decision-making around family presence during resuscitation occurred in time poor environments and in the absence of local institutional guidelines. Clinicians appeared to be motivated by doing "what's best" for patients and families when allowing or denying family presence during resuscitation. However, their individual interpretations of "what's best" was subjective and did not always coincide with family preferences or with current evidence that promotes family presence during resuscitation as beneficial. The decision to allow or deny family presence during resuscitation is complex, and often impacted by personal preferences and beliefs, setting norms and tensions between clinicians and consumers. As a result, many families are missing the chance to be with their loved ones at the end of life. The introduction of institutional guidelines and policies would help to establish what safe and effective practice consists of, reduce value-laden decision-making and guide beneficent decision-making. These findings highlight current deficits in decision-making around FPDR and could prompt the introduction of clinical guidelines and policies and in turn promote the

    Delirium is common, affecting at least 20% of older hospital inpatients. It is widely accepted that delirium is associated with dementia but the degree of causation within this relationship is unclear. Previous studies have been limited by incomplete ascertainment of baseline cognition or a lack of prospective delirium assessments. There is an urgent need for an improved understanding of the relationship between delirium and dementia given that delirium prevention may plausibly impact upon dementia prevention. A well-designed, observational study could also answer fundamental questions of major importance to patients and their families regarding outcomes after delirium. The Delirium and Cognitive Impact in Dementia (DECIDE) study aims to explore the association between delirium and cognitive function over time in older participants. In an existing population based cohort aged 65 years and older, the effect on cognition of an episode of delirium will be measured, independent of baseline cognition and illness severity. The predictive value of clinical parameters including delirium severity, baseline cognition and delirium subtype on cognitive outcomes following an episode of delirium will also be explored. Over a 12 month period, surviving participants from the Cognitive Function and Ageing Study II-Newcastle will be screened for delirium on admission to hospital. At the point of presentation, baseline characteristics along with a number of disease relevant clinical parameters will be recorded. The progression/resolution of delirium will be monitored. In those with and without delirium, cognitive decline and dementia will be assessed at one year follow-up. We will evaluate the effect of delirium on cognitive function over time along with the predictive value of clinical parameters. This study will be the first to prospectively elucidate the size of the effect of delirium upon cognitive decline and incident dementia. The results will be used to inform future

    2012-01-01

    Although medical and travel plans gathered from pre-travel interviews are used to decide the provision of specific pre-travel health advice and vaccinations, there has been no evaluation of the relevance of this strategy. In a prospective study, we assessed the agreement between pre-travel plans and post-travel history and the effect on advice regarding the administration of vaccines and recommendations for malaria prevention. We included prospectively all consenting adults who had not planned an organized tour. Pre- and post-travel information included questions on destination, itineraries, departure and return dates, access to bottled water, plan of bicycle ride, stays in a rural zone, and close contact with animals. The outcomes measured included: agreement between pre- and post-travel itineraries and activities; and the effect of these differences on pre-travel health recommendations, had the traveler gone to the actual versus intended destinations for actual versus intended duration and activities. Three hundred and sixty-five travelers were included in the survey, where 188 (52%) were males (median age 38 years). In 81(23%) travelers, there was no difference between pre- and post-travel history. Disagreement between pre- and post-travel history were the highest for stays in rural zones or with local people (66% of travelers), close contact with animals (33%), and bicycle riding (21%). According to post-travel history, 125 (35%) travelers would have needed rabies vaccine and 9 (3%) typhoid fever vaccine. Potential overprovision of vaccine was found in travelers. A change in the malaria prescription would have been recommended in 18 (5%) travelers. Pre-travel history does not adequately reflect what travelers do. However, difference between recommendations for the actual versus intended travel plans was only clinically significant for the need for rabies vaccine. Particular attention during pre-travel health counseling should focus on the risk of rabies, the

    The treatment of cancer associated thrombosis (CAT) is well established, with level 1A evidence to support the recommendation of a low molecular weight heparin (LMWH) by daily injection for 3-6 months. However, registry data suggest compliance to clinical guidelines is poor. Clinicians face particular challenges in treating CAT in advanced cancer patients due to shorter life expectancy, increased bleeding risk and concerns that self injection may be too burdensome. For these reasons decision making around the diagnosis and management of CAT in people with advanced cancer, can be complex, and should focus on its likely net benefit for the patient. We explored factors that influence doctors' decision making in this situation and sought to gain an understanding of the barriers and facilitators to the application of best practice. Think aloud exercises using standardised case scenarios, and individual in depth interviews were conducted. All were transcribed.

    2017-09-01

    Why do men decide to have a child by surrogacy as a single parent? Reasons included feeling that it was the right time (i.e. having 'worked through' concerns about single parenthood; career and financial stability; a fear of getting older; no longer wanting to wait for the 'right' relationship), external encouragement, a desire to reproduce and a fear of separation/divorce. Because no research has been conducted on single fathers who used surrogacy, their characteristics, motivations and experiences are unknown. This study used a cross-sectional design as part of a larger, multi-method, multi-informant investigation of single father families created by surrogacy. Multiple strategies were used to recruit participants (i.e. from an association of gay parents, Facebook groups of single parents and snowballing) between November 2016 and April 2017. Data were obtained from 33 Italian single fathers (Meanage = 47.33 years, SD = 4.63), most of whom self-identified as gay (n = 24, 72.7%). In-depth semi-structured interviews were conducted in family homes (n = 20, 60.6%) or over Skype (n = 13, 39.4%). Each interview lasted approximately 40 min and was audio recorded, transcribed verbatim and analyzed using thematic and qualitative content analysis, with the aid of the software package MAXQDA. Where appropriate, a two-sided Fisher's exact test was used to compare the gay and heterosexual fathers, and illustrative quotations were reported. Although all of the single men had experienced mature relationships, about one-third of the fathers (n = 10, 30.3%) had never thought of having a child and the majority of the heterosexual men (n = 7, 77.8%, P = 0.05) had tried to conceive in previous relationships. The gay and heterosexual men differed in their preferred path to parenthood (P = 0.01), with the former (n = 17, 70.8%) having always preferred surrogacy and the latter (n = 6, 66.7%) having considered or attempted conception via casual sex with women. Irrespective of their

    Normochromic normocytic anemia is a common complication in chronic kidney disease (CKD) and is associated with many adverse clinical consequences. Erythropoiesis-stimulating agents (ESAs) act to replace endogenous erythropoietin for patients with end-stage renal disease having anemia. Today, ESAs remain the main tool for treating anemia associated with CKD. In current practice, the use of ESA is not limited to the patients on renal replacement therapy but has extended to nondialysis patients under palliative care (PC). Current evidence on ESA usage in patients with CKD decided to forego dialysis often have to take reference from studies conducted in other groups of patients with CKD, including pre-dialysis patients and those on renal replacement therapy. There is paucity of studies targeting use of ESAs in renal PC patients. Small-scale retrospective study in renal PC patients had suggested clinical advantage of ESAs in terms of hemoglobin improvement, reduction in fatigue, and hospitalization rate. With the expected growth in elderly patients with CKD decided to forego dialysis and manage conservatively, there remains an urgent need to call for large-scale prospective trial in exploring efficacy of ESAs in this population, targeting on quality of life and symptoms improvement outcome. This article also reviews the mechanism of action, pharmacology, adverse effects, and clinical trial evidence for ESA in patients with CKD under renal PC.

    Despite the fact that long acting family planning methods reduce population growth and improve maternal health, their utilization remains poor. Therefore, this study assessed the prevalence of long acting and permanent family planning method utilization and associated factors among women in reproductive age groups who have decided not to have more children in Gondar city, northwest Ethiopia. An institution based cross-sectional study was conducted from August to October, 2015. Three hundred seventeen women who have decided not to have more children were selected consecutively into the study. A structured and pretested questionnaire was used to collect data. Both bivariate and multi-variable logistic regressions analyses were used to identify factors associated with utilization of long acting and permanent family planning methods. The multi-variable logistic regression analysis was used to investigate factors associated with the utilization of long acting and permanent family planning methods. The Adjusted Odds Ratio (AOR) with the corresponding 95% Confidence Interval (CI) was used to show the strength of associations, and variables with a P-value of <0.05 were considered statistically significant. In this study, the overall prevalence of long acting and permanent contraceptive (LAPCM) method utilization was 34.7% (95% CI: 29.5-39.9). According to the multi-variable logistic regression analysis, utilization of long acting and permanent contraceptive methods was significantly associated with women who had secondary school, (AOR: 2279, 95% CI: 1.17, 4.44), college, and above education (AOR: 2.91, 95% CI: 1.36, 6.24), history of previous utilization (AOR: 3.02, 95% CI: 1.69, 5.38), and information about LAPCM (AOR: 8.85, 95% CI: 2.04, 38.41). In this study the prevalence of long acting and permanent family planning method utilization among women who have decided not to have more children was high compared with previous studies conducted elsewhere.

Preview of the new CERN website to be published on 5 May. Opinion is split among CERNois when talking about Dan Brown’s book Angels & Demons. Should he be praised for bringing particle physics into the spotlight or should he be demonised for the ‘creative liberties’ he took - for example, although it would be useful for the international collaborations, CERN doesn’t actually have its own private airport and supersonic jet.

    Hughes, David; Doheny, Shane

    2011-11-01

    This paper examines audio-recorded data from meetings in which NHS managers decide whether to fund high-cost drugs for individual patients. It investigates the work of a Welsh individual patient commissioning (IPC) panel responsible for sanctioning the purchase of 'un-commissioned' treatments for exceptional cases. The case study presented highlights the changing rationales used for approving or denying a cancer drug, Tarceva, during a period when NICE first suggested it was not cost effective, but then changed its position in a final technology appraisal recommending use when the cost did not exceed that of an alternative product. Our data show how decisions taken in the shadow of NICE guidance remain complex and subject to local discretion. Guidance that takes time to prepare, is released in stages, and relates to particular disease stages, must be interpreted in the context of particular cases. The case-based IPC panel discourse stands in tension with the standardised population-based recommendations in guidance. Panel members, who based their decisions on the central notions of 'efficacy' and 'exceptionality', often struggled to apply NICE information on cost-effectiveness to their deliberations on efficacy (clinical effectiveness). The case study suggests that the complex nature of decision making makes standardization of outcomes very difficult to achieve, so that local professional judgement is likely to remain central to health care rationing at this level.

    Risk-reducing procedures can be offered to people at increased cancer risk, but many procedures can have iatrogenic effects. People therefore need to weigh risks associated with both cancer and the risk-reduction procedure in their decisions. By reviewing relevant literature on breast cancer (BC) risk reduction, we aimed to understand how women at relatively high risk of BC perceive their risk and how their risk perceptions influence their decisions about risk reduction. Synthesis of 15 qualitative studies obtained from systematic searches of SCOPUS, Web of Knowledge, PsychINFO, and Medline electronic databases (inception-June 2015). Women did not think about risk probabilistically. Instead, they allocated themselves to broad risk categories, typically influenced by their own or familial experiences of BC. In deciding about risk-reduction procedures, some women reported weighing the risks and benefits, but papers did not describe how they did so. For many women, however, an overriding wish to reduce intense worry about BC led them to choose aggressive risk-reducing procedures without such deliberation. Reasoning that categorisation is a fundamental aspect of risk perception, we argue that patients can be encouraged to develop more nuanced and accurate categorisations of their own risk through their interactions with clinicians. Empirically-based ethical reflection is required to determine whether and when it is appropriate to provide risk-reduction procedures to alleviate worry. © 2016 The Authors.

    2012-02-01

    To increase our understanding of how pregnant women experience early ultrasound examination that includes a risk assessment for chromosomal anomalies and how such women perceive the test results. Qualitative study at St. Olavs Hospital in Norway. Both pre- and post-examination interviews were conducted with ten pregnant women who underwent risk assessment for chromosomal anomalies. Grounded theory was used to analyse the results. The study generated a core category (I want a choice, but I don't want to decide), which related to the conflict between choice and decision making. There were also five main categories (existential choices, search for knowledge, anxiety, feeling of guilt and counselling and care). The main categories describe the complex feelings experienced by the women regarding the risk assessment. Factors contributing to the difficulty of choice included loss of control and coping, emotional connection to the fetus and social pressure. As the women sought independent choices without any external influence, they also felt greater responsibility. The women's understanding of the actual risk varied, and they used different types of logic and methods to evaluate the risk and reach a decision. The pregnant women in this study wanted prenatal diagnostic information and easy access to specialty services. Stress-related feelings and non-transparent information about the actual and perceived risks as well as personal moral judgments made the decision-making process complicated. Improved distribution of information and frequent contact with health professionals may help such women to make informed choices in accordance with their values and beliefs.

    Contemporary approaches to medical decision-making advise that clinicians should respect patients' decisions. However, patients' decisions are often shaped by heuristics, such as being guided by emotion, rather than by objective risk and benefit. Risk-reducing mastectomy (RRM) decisions focus this dilemma sharply. RRM reduces breast cancer (BC) risk, but is invasive and can have iatrogenic consequences. Previous evidence suggests that emotion guides patients' decision-making about RRM. We interviewed patients to better understand how they made decisions about RRM, using findings to consider how clinicians could ethically respond to their decisions. Qualitative face-to-face interviews with 34 patients listed for RRM surgery and two who had decided against RRM. Patients generally did not use objective risk estimates or, indeed, consider risks and benefits of RRM. Instead emotions guided their decisions: they chose RRM because they feared BC and wanted to do 'all they could' to prevent it. Most therefore perceived RRM to be the 'obvious' option and made the decision easily. However, many recounted extensive post-decisional deliberation, generally directed towards justifying the original decision. A few patients deliberated before the decision because fears of surgery counterbalanced those of BC. Patients seeking RRM were motivated by fear of BC, and the need to avoid potential regret for not doing all they could to prevent it. We suggest that choices such as that for RRM, which are made emotionally, can be respected as autonomous decisions, provided patients have considered risks and benefits. Drawing on psychological theory about how people do make decisions, as well as normative views of how they should, we propose that practitioners can guide consideration of risks and benefits even, where necessary, after patients have opted for surgery. This model of practice could be extended to other medical decisions that are influenced by patients' emotions.

    Procedures for determining refugee status across Europe are being speeded up, despite the high prevalence of mental health difficulties among asylum seekers. An assurance given is that ''vulnerable applicants'' will be identified and excluded from accelerated procedures. Although experts have recommended assessments to be undertaken by experienced clinicians, this is unlikely to happen for political and financial reasons. Understanding how non-clinically qualified personnel perform assessments of mental health issues is timely and crucial. Misrecognition of refugees due to the inappropriate use of accelerated procedures involves the risk of returning the very people who have the right to protection from further persecution. To examine the decision making of immigration lawyers, who are an example of a group of nonclinicians who decide when and whether to refer asylum-seekers for psychiatric assessment. Semi-structured interviews were conducted with 12 legal representatives working with people seeking refugee or human rights protection in the United Kingdom. The resultant material was analysed using Framework Analysis. Themes clustered around the legal case, the client, the representative and the systems, all with sub-themes. A mapping exercise integrated these themes to show how representatives brought together questions of (1) evidential reasons for a report, influenced by their legal, psychological and case law knowledge, and (2) perceived evidence of mental distress, influenced by professional and personal experiences and expectations. The legal representatives interviewed were well-informed and trained in psychological issues as well as clearly dedicated to their clients. This helped them to attempt quasi-diagnoses of common mental health problems. They nonetheless demonstrated stereotypical understanding of post-traumatic stress disorder and other possible diagnoses and the role of subjectivity. The study has implications for other groups - particularly those

    The purpose of this study is to examine the perceptions of primary care physicians (PCPs) regarding indications, contraindications, risks and benefits of total joint arthroplasty (TJA) and their confidence in selecting patients for referral for TJA. PCPs recruited from among those providing care to participants in an established community cohort with hip or knee osteoarthritis (OA). Self-completed questionnaires were used to collect demographic and practice characteristics and perceptions about TJA. Confidence in referring appropriate patients for TJA was measured on a scale from 1 to 10; respondents scoring in the lowest tertile were considered to have 'low confidence'. Descriptive analyses were conducted and multiple logistic regression was used to determine key predictors of low confidence. 212 PCPs participated (58% response rate) (65% aged 50+ years, 45% female, 77% >15 years of practice). Perceptions about TJA were highly variable but on average, PCPs perceived that a typical surgical candidate would have moderate pain and disability, identified few absolute contraindications to TJA, and overestimated both the effectiveness and risks of TJA. On average, PCPs indicated moderate confidence in deciding who to refer. Independent predictors of low confidence were female physicians (OR = 2.18, 95% confidence interval (CI): 1.06-4.46) and reporting a 'lack of clarity about surgical indications' (OR = 3.54, 95% CI: 1.87-6.66). Variability in perceptions and lack of clarity about surgical indications underscore the need for decision support tools to inform PCP - patient decision making regarding referral for TJA.

    Full Text Available Abstract Background There is increased incidence of new cases of type 1 diabetes in children younger than 15 years. The debate concerning where best to manage newly diagnosed children continues. Some units routinely admit children to hospital whilst others routinely manage children at home. A Cochrane review identified the need for a large well-designed randomised controlled trial to investigate any significant differences in comprehensive short and long-term outcomes between the two approaches. The DECIDE study will address these knowledge gaps, providing high quality evidence to inform national and international policy and practice. Methods/Design This is a multi-centre randomised controlled trial across eight UK paediatric diabetes centres. The study aims to recruit 240 children newly diagnosed with type 1 diabetes and their parents/carers. Eligible patients (aged 0-17 years will be remotely randomised to either 'hospital' or 'home' management. Parents/carers of patients will also be recruited. Nursing management of participants and data collection will be co-ordinated by a project nurse at each centre. Data will be collected for 24 months after diagnosis; at follow up appointments at 3, 12 and 24 months and every 3-4 months at routine clinic visits. The primary outcome measure is patients' glycosylated haemoglobin (HbA1c at 24 months after diagnosis. Additional measurements of HbA1c will be made at diagnosis and 3 and 12 months later. HbA1c concentrations will be analysed at a central laboratory. Secondary outcome measures include length of stay at diagnosis, growth, adverse events, quality of life, anxiety, coping with diabetes, diabetes knowledge, home/clinic visits, self-care activity, satisfaction and time off school/work. Questionnaires will be sent to participants at 1, 12 and 24 months and will include a questionnaire, developed and validated to measure impact of the diagnosis on social activity and independence.

    Doyle, Kevin S.

    The New Jersey Interdistrict School Choice Program allows parents to send their students to schools outside of their local school district. Determining why parents send their students to choice schools is important to school leaders who are trying to attract new students, as well as those who are trying to retain their current students. This study examined the reasons why parents decided to send their students to the Magnet Program for Math and Science (MP4M&S), a school choice program in a suburban school district in northwest New Jersey, during the 2015- 2016 school year. A large volume of research has focused on school choice programs in urban and poor communities. This study addressed the gap in the research by focusing on an affluent suburban school district. This mixed methods study focused on three areas, why parents choose to send their students to the MP4M&S, what criteria they used to make their decision, and where they got their information. Research shows that these three areas of focus can be influenced by parental level of education, socioeconomic status, geographic location, academic rigor, school quality, and school environment. Parents from different groups, based upon their out-of-district status, were interviewed. The information from the interviews was used to focus a survey that was given to the families of all 137 students in the MP4M&S during the 2015-2016 school year. The results of this study show that parents found the academic focus, academic rigor, the school environment, the original research project, the activity offerings, and the economics involved in attending the program to be important attractors. The study also found that the Information Nights, the school website, and interactions with members of the MP4M&S community to be important sources of information. Finally, the study found that there were few differences between in and out-of-district parents when assigning importance to both the attractors and the sources in the study

    Here are presented and discussed the data concerning the concentration of vanadium in some soils of Tolfa mountains. The aim of this study was to evaluate the fall out connected with the emissions of the oil power plants of Civitavecchia. The authors have analysed the considered by us elements V, Ti, Mn, Al and Si, using the instrumental neutron activation analysis. The vanadium because is presented in the oil in higher concentrations in comparison with the other elements and so as an element which characterizes the emissions, while Ti, Mn, Al and Si, due to their terrestrial origin, are useful to put in evidence the contribution due to the lithological component. From the obtained data and in agreement with the theoretical estimations according to the atmospheric fall out, the authors convinced that during the operating time of the oil power plants of Civitavecchia, one can not observe appreciable variations of vanadium in some soils of Tolfa mountains. The obtained data can be useful in the other future studies which will aim to evaluate the entity of the contribution of such elements coming from the oil power plants of Civitavecchia.

    Extreme premature child's long-term prognostic is getting better and better known, and if a resuscitation procedure is possible at birth, it won't guarantee survival or a survival free of disability. Incertitude toward individual prognosis and outcome for those children remains considerable. In this field, we are at the frontier of medical knowledge and the answer to the question, "how to decide the ante and postnatal care" is crucial. This work is focused on this problematic of decision-making in the context of extreme prematurity. It attempts to deconstruct this concept and to explicit its stakes.

    Extreme premature child's long-term prognostic is getting better and better known, and if a resuscitation procedure is possible at birth, it won't guarantee survival or a survival free of disability. Incertitude toward individual prognosis and outcome for those childs remains considerable. In this field, we are at the frontier of medical knowledge and the answer to the question, "how to decide the ante and postnatal care?" is crucial. This work is focused on this problematic of decision making in the context of extreme prematurity. It attempts to deconstruct this concept and to explicit its stakes. Thus, with the support of the medical sources and of philosophical debates, we tried to build a decision-making procedure that complies with the ethical requirements of medical care, accuracy, justice and equity.

    The plant hormone abscisic acid (ABA) has been implicated in a variety of physiological responses ranging from seed dormancy to stomatal conductance. Recently, three groups have reported the molecular identification of three disparate ABA receptors. Unlike the identification of other hormone receptors, in these three cases high affinity binding to ABA rather than the isolation of ABA insensitive mutants led to these receptor genes. Interestingly, two of the receptors encode genes involved in floral timing and chlorophyll biosynthesis, which are not considered traditional ABA responses. And the third receptor has been clouded in issues of its molecular identity. To clearly determine the roles of these genes in ABA perception it will require placing of these ABA-binding proteins into the rich ABA physiological context that has built up over the years.

    Two reports in this issue address the important topic of clinical decision making. Dual process theory has emerged as the dominant model for understanding the complex processes that underlie human decision making. This theory distinguishes between the reflexive, autonomous processes that characterize intuitive decision making and the deliberate reasoning of an analytical approach. In this commentary, the authors address the polarization of viewpoints that has developed around the relative merits of the two systems. Although intuitive processes are typically fast and analytical processes slow, speed alone does not distinguish them. In any event, the majority of decisions in clinical medicine are not dependent on very short response times. What does appear relevant to diagnostic ease and accuracy is the degree to which the symptoms of the disease being diagnosed are characteristic ones. There are also concerns around some methodological issues related to research design in this area of enquiry. Reductionist approaches that attempt to isolate dependent variables may create such artificial experimental conditions that both external and ecological validity are sacrificed. Clinical decision making is a complex process with many independent (and interdependent) variables that need to be separated out in a discrete fashion and then reflected on in real time to preserve the fidelity of clinical practice. With these caveats in mind, the authors believe that research in this area should promote a better understanding of clinical practice and teaching by focusing less on the deficiencies of intuitive and analytical systems and more on their adaptive strengths.

    This paper challenges the traditional view that unemployment is high because insiders determine the union wage. The insiders in this paper are characterised by being more efficient when they search for a job than the outsiders, implying that they experience relatively less unemployment. We assume...... that wages are determined by a monopoly union and further that a union leader is elected by a majority voting rule. Insiders may prefer a lower wage that outsiders, implying the possibility of lower unemployment when insiders are decisive in the union than if outsiders were decisive in the union....

    Full Text Available The purpose of this article is to explore the mode of production of judicial sentences drafted by constitutional courts in Europe. The natural object of study of the constitutional theory is the analysis of this final product of judicial creation of Law by Constitutional Courts. However, the doctrine has not given sufficient attention –from a comparative law perspective– to the mechanisms and procedures that lead to the decisions of these institutions. Thus, this document will classify the different types of decision-making processes in the courts, analyzing the stages that make up the «mode of production», from the study of the decisions of the Supreme Court of the United States, the Constitutional Council of the French Republic, The Constitutional Court of Italy and the Federal Constitutional Court of Germany. At the end of the paper, some conclusions are made about the period of the magistrates, their party affiliation, the temporary restrictions of deliberation and institutional factors such as the number of attendees or the personalization of its members.

    This document proposes reflections and thoughts about the future of nuclear energy in a changing context, notably in terms of climate challenges and of restructuring of the nuclear sector. The authors first outline and discusses that nuclear energy is today indispensable to face climate challenge, but must still overcome many difficulties regarding cooperation, standards and waste management. They outline that the European Union must integrate nuclear energy into a more ambitious energetic strategy aimed at securing energy supply, economic competitiveness and its contribution to the struggle against climate change, and should be based on an actual value of carbon, and an easier financing of low carbon energy production infrastructures, whatever the chosen technology be. In a third part, the authors outline that the French State must take its responsibilities in order nuclear industry to remain an asset for France: the nuclear fleet renewal must be prepared (renovation of existing reactors and construction of new ones), renewable energies must be developed to reach an energy mix which would be one of the lowest carbonated one. In this respect, objectives defined by the law on energy transition should be reviewed to optimize economic and environmental costs. Finally, the authors state that the French nuclear industry should perform a competitiveness leap at the occasion of the current restructuring of activities between EDF and Areva. A set of recommendations is proposed to address these issues

    Full Text Available In this paper, we present an incentivized experiment to investigate the degree of loss aversion when people make decisions for their current selves and future selves under risk. We find that when participants make decisions for their future selves, they are less loss averse compared to when they make decisions for their current selves. This finding is consistent with the interpretation of loss aversion as a bias in decision-making driven by emotions, which are reduced when making decisions for future selves. Our findings endorsed the external validity of previous studies on the impact of emotion on loss aversion in a real world decision-making environment.

  4. Childbirth -- a question for couples to decide.

    The decrease in Japan's total fertility rate (TFR) to a new low of 1.46 in 1993 may reinforce concern about the rapid aging of Japanese society and strengthen government and business pronatalist attitudes, says Yuriko Ashino, deputy executive director, Family Planning Federation of Japan. Ashino calls for fully paid child-care leave as well as a change in the value system that women should raise children. According to the Ministry of Health and Welfare, the TFR dropped 0.4 points from 1.50 in 1992 to reach the 1.46 mark, the second-lowest TFR in the industrialized world, after Italy's 1.26. The Ministry also reported that the number of babies born in Japan fell by 20,672 from 1992 to 1.18 million in 1993. At the peak in 1973, 2.9 million babies were born. The decline in fertility is attributed to the growing trend for women to marry later and bear children later. The average age at first marriage for women rose from 26 in 1992 to 26.1 years in 1993, while the average age at first birth rose to a record 27.2 years in 1993. However, advances in medical technologies allow women to bear children much later, boosting a woman's ability to have more than 1.46 children. Arguments from the government that the higher education of women in Japan is affecting the birthrate are incorrect, since women of all educational backgrounds are having fewer children. The government might like women to stay home not only to rear children, but to care for the increasing number of elderly. The government should place more emphasis on men's responsibility for contraception, child-rearing, and household work. The 1994 UN International Conference on Population and Development in September, should consider Japan's fertility issues in relation to other countries'. Japan is encouraging smaller, happier families in developing countries, but it is urging Japanese women to bear more children.

  6. Room temperature PL efficiency of InGaN/GaN quantum well structures with prelayers as a function of number of quantum wells

    We report on the effects of varying the number of quantum wells (QWs) in an InGaN/GaN multiple QW (MQW) structure containing a 23 nm thick In0.05Ga0.95N prelayer doped with Si. The calculated conduction and valence bands for the structures show an increasing total electric field across the QWs with increasing number of QWs. This is due to the reduced strength of the surface polarisation field, which opposes the built-in field across the QWs, as its range is increased over thicker samples. Low temperature photoluminescence (PL) measurements show a red shifted QW emission peak energy, which is attributed to the enhanced quantum confined Stark effect with increasing total field strength across the QWs. Low temperature PL time decay measurements and room temperature internal quantum efficiency (IQE) measurements show decreasing radiative recombination rates and decreasing IQE, respectively, with increasing number of QWs. These are attributed to the increased spatial separation of the electron and hole wavefunctions, consistent with the calculated band profiles. It is also shown that, for samples with fewer QWs, the reduction of the total field across the QWs makes the radiative recombination rate sufficiently fast that it is competitive with the efficiency losses associated with the thermal escape of carriers.

    The aim of this study was to evaluate the predictive role of percentage of free prostate-specific antigen (%fPSA) cut-points in prostate cancer (PCa) detection in patients with total PSA (tPSA) levels between 2.5 ng/mL and 10.0 ng/mL. In total, 1321 consecutive initial transrectal ultrasound (TRUS)-guided 12-core biopsies performed between 2005 and 2011 were evaluated retrospectively. Benign pathologies, high-grade prostatic intraepithelial neoplasia, and atypical small acinary proliferations were categorized as noncancerous (benign), and prostate adenocarcinomas were categorized as cancerous (malignant). The patients were categorized according to: Catalona's published %fPSA categories ( 25%); digital rectal examination (DRE) results [benign (negative) or suspicious of malignancy (positive)]. There was a significant relationship between the %fPSA cut-points and detection of PCa in DRE-negative patients. The presence of a 10% cut-point increased the probability of PCa threefold. The %fPSA was significantly more related to PCa than the tPSA value in receiver operating characteristic (ROC) curve analyses (p = 0.001). Based on our findings, a lower %fPSA, especially <10%, is an important parameter when deciding whether to perform a biopsy on patients with a tPSA between 2.5 ng/mL and 10 ng/mL. Copyright © 2015.

    Anecdotally, it is often stated that the majority of students that enter the geosciences usually do so sometime after their initial entrance into college. With the objective of providing concrete and useful information for individuals developing programs for inspiring interest in the Geosciences amongst pre-college students and trying to increase the number of freshman Geoscience majors, we conducted a critical incident study. Twenty-two students, who were undergraduate or graduate Geoscience majors, were asked, "Why did you decide to major in the Geosciences?" in a series of interviews. Their responses were then used to identify over 100 critical incidents, each of which described a specific behavior that was causally responsible for a student's choice to major in Geoscience. Using these critical incidents, we developed a preliminary taxonomy that is comprised of three major categories: Informal Exposure to the Geosciences (e.g., outdoor experiences, family involvement), Formal Exposure to the Geosciences (e.g., academic experiences, program participation) and a Combined Informal and Formal Exposure (e.g., media exposure). Within these three main categories we identified thirteen subcategories. These categories and subcategories, describe, classify, and provide concrete examples of strategies that were responsible for geosciences career choices. As a whole, the taxonomy is valuable as a new, data-based guide for designing geosciences recruitment programs for the pre-college student population.

  9. Mapping infectious disease hospital surge threats to lessons learnt in Singapore: a systems analysis and development of a framework to inform how to DECIDE on planning and response strategies.

    Hospital usage and service demand during an Infectious Disease (ID) outbreak can tax the health system in different ways. Herein we conceptualize hospital surge elements, and lessons learnt from such events, to help build appropriately matched responses to future ID surge threats. We used the Interpretive Descriptive qualitative approach. Interviews (n = 35) were conducted with governance and public health specialists; hospital based staff; and General Practitioners. Key policy literature in tandem with the interview data were used to iteratively generate a Hospital ID Surge framework. We anchored our narrative account within this framework, which is used to structure our analysis. A spectrum of surge threats from combinations of capacity (for crowding) and capability (for treatment complexity) demands were identified. Starting with the Pyramid scenario, or an influx of high screening rates flooding Emergency Departments, alongside fewer and manageable admissions; the Reverse-Pyramid occurs when few cases are screened and admitted but those that are, are complex; during a 'Black' scenario, the system is overburdened by both crowding and complexity. The Singapore hospital system is highly adapted to crowding, functioning remarkably well at constant near-full capacity in Peacetime and resilient to Endemic surges. We catalogue 26 strategies from lessons learnt relating to staffing, space, supplies and systems, crystalizing institutional memory. The DECIDE model advocates linking these strategies to types of surge threats and offers a step-by-step guide for coordinating outbreak planning and response. Lack of a shared definition and decision making of surge threats had rendered the procedures somewhat duplicative. This burden was paradoxically exacerbated by a health system that highly prizes planning and forward thinking, but worked largely in silo until an ID crisis hit. Many such lessons can be put into play to further strengthen our current hospital governance

    Full Text Available Abstract The purpose of this study was to assess the validity and reliability of Relationship Deciding Scale (Vennum & Fincham, 2011 for Turkish culture. The sample of the study consisted of 880 students (EFA=439, CFA=441 studying at Karadeniz Technical University. Criterion-related validity, exploratory and confirmatory factor analyses were conducted for the validity of RDS while internal consistency, split half and test-retest techniques were performed to examine the reliability of RDS. Exploratory factor analysis (EFA revealed that the scale had two-factor structures. However, two items were removed from the scale because they didn't have appropriate factor loadings. The scale consisting of 10 items explained 58.97% of the total variance. The results of confirmatory factor analysis (CFA indicated that the model was compatible with the data. In the reliability analysis for EFA and CFA samples, Cronbach alpha coefficients were found as .87 and .86 respectively. Internal consistency coefficients of subscales were found as .83 and .80 for “Relationship Confidence”, .82 and .84 for “Directing Relationship”. According to test-retest reliability analysis results, the whole scale’s coefficient was r= .67. In addition, as a result of criterion validity analysis, correlations (r= .33 between Self-Control Scale (Duyan, Gülden & Gelbal, 2012 and Relationship Deciding Scale (RDS were found to be statistically significant. In conclusion, these findings suggest that RDS, which has two-factor structures with 10 items, can be suggested as a valid and reliable instrument in Turkish culture.

  13. Big Data and Consumer Participation in Privacy Contracts: Deciding who Decides on Privacy

    Directory of Open Access Journals (Sweden)

    Michiel Rhoen

    2015-02-01

    Full Text Available Big data puts data protection to the test. Consumers granting permission to process their personal data are increasingly opening up their personal lives, thanks to the “datafication” of everyday life, indefinite data retention and the increasing sophistication of algorithms for analysis.The privacy implications of big data call for serious consideration of consumers’ opportunities to participate in decision-making processes about their contracts. If these opportunities are insufficient, the resulting rules may represent special interests rather than consumers’ needs. This may undermine the legitimacy of big data applications.This article argues that providing sufficient consumer participation in privacy matters requires choosing the best available decision making mechanism. Is a consumer to negotiate his own privacy terms in the market, will lawmakers step in on his behalf, or is he to seek protection through courts? Furthermore is this a matter of national law or European law? These choices will affect the opportunities for achieving different policy goals associated with the possible benefits of the “big data revolution”.

    A wide programme on cementation of radioactive and/or toxic wastes is being conducted at ENEA (Italian Agency for Energy, New Technologies and the Environment) laboratories. The main goal of the research work is to achieve solidified products which are reliable for transport and final disposal, as well as, to study possible reuse for civil purposes. Several characterization tests are made aiming at the optimization of process parameters and the verification of the quality of the final waste forms. Particular attention is being devoted to the problems related to the waste-matrix interaction, because no waste can be considered 'inert' from this point of view. It is therefore necessary to investigate the nature and the amount of such interactions through an accurate study of the chemical behaviour of the main waste components. That should allow researchers to get useful information to prevent the embedded wastes from causing deleterious effects to the solidification matrix.

    The application of Life Cycle Assessment (LCA) methodology as environmental balance tool is particularly suitable for the study of complex system such as municipal solid waste (MSW) collection, treatment and disposal systems. In this case a detailed analysis is carried out referring to an overall environmental balance based on two different waste treatments: land filling and incineration. The comparison carried out based on the LCA methodology and referring to specific process assumptions allowed to foreground that waste to energy treatments get a net overall balance lower than all the different land filling options, referring also to energy recovery from collected biogas. [Italian] La applicazione di metodologie di bilancio ambientale LCA (Life Cycle Assessment) si adatta particolarmente allo studio disistemi complessi quali quelli di raccolta, trattamento e smaltimento di rifiuti. In questo caso viene affrontata nel dettaglio la valutazione in termini di bilancio complessivo di diverse opzioni di trattamento basate su posa a discarica e trattamento termico. Il confronto effettuato mediante il percorso metodologico seguito, ha permesso di valutare, sulla base delle ipotesi di processi fatte, come il trattamento termico con recupero energetico abbia un bilancio netto ambientale inferiore rispetto a qualsiasi opzione di posa a discarica, anche dotata di recupero energetico dal biogas.

    The point of conflict between the majority and minority views is the existence of consideration. There is no question that hospitals are required to adopt medical staff bylaws, nor is there any doubt hornbook law states the performance of a pre-existing duty does not constitute consideration. Therefore, the issue of law is whether the hospital's grant of privileges and the physician's agreement to abide by the bylaws is separate or different "consideration" sufficient to justify the creation of a contract.

    1994-12-01

    The pipe manufacturers who are grouped together in the EuHP have reached agreement on offering bare copper wire as `their` compatible standard sensor. This is not a new decision: This always was the case, and was always sold as such if the customer did not express any particular wishes of their own in this respect when placing the order. The inspiration for this action is, rather, concern with some monitoring systems. These have become the subject of gossip over the past few years, and we too view this development with concern. Only the `Nordic system` and the resistance comparison measuring system process are unaffected by this. Against this background, attempts are also being made to have copper declared as the sole standard. This decision is in fact only a logical defence of interests, because compatibility between not only the pipe manufacturers but also between the laying processes is only available with the resistance wire - and that has always been the case. It is important not to treat the topic as an `article of faith`, but in such a way that the way is open to solutions which really are acceptable to all parties. (orig./KO) [Deutsch] Die im EuHP zusammengefassten Rohrhersteller haben sich nun darauf verstaendigt, kuenftig zwei Kupferadern als `ihren` Standardsensor anzubieten. Das ist keine neue Entscheidung, denn das war schon immer so und wurde immer dann verkauft, wenn der Kunde keine feste eigene Meinung in die Auftragsvergabe einbrachte. Neu ist, dass man kuenftig `keine stoerenden Komponenten` in den Rohren mehr will und dass man das `Kupfersystem` offensiv nach aussen traegt. Mit diesem Hintergrund ist es verstaendlich, dass manche bei dieser Gelegenheit gleich den Sensor, der ihnen als Rohrhersteller am angenehmsten ist, zum Standard erklaeren moechten. Dieser Beschluss ist konsequente Interessenwahrnehmung. Denn: Wirkliche Kompatibilitaet nicht nur zwischen den Verlegeverfahren, gibt es mit dem Widerstandsdraht schon seit ueber 20 Jahren. Ob der Vorstoss mehr Vor- als Nachteile bringt, muessen daher die entscheiden, die als Auftraggeber Nutzen aus der Fernheizleitung und Sicherheit fuer das investierte Geld aus dem Sicherheitssystem ziehen wollen. Eine Fehlentscheidung waere endgueltig und kritisch fuer die Fernwaerme. (orig./KO)

  11. Is raised helicobacter pylori antibody titre enough to decide retreatment

    International Nuclear Information System (INIS)

    Bibi, S.; Ahmed, W.; Arif, A.; Alam, S.E.

    2011-01-01

    Background: Helicobacter pylori infection causes a rise in its antibodies which take almost a year to come to baseline following successful eradication treatment. Checking these values in between a year may give falsely high values and many patients may thus be over treated. Aims: To serially determine Helicobacter pylori antibody titres in patients after giving them triple therapy for H. pylori eradication and see how these values drop over time. Study type, Settings and duration: Longitudinal study conducted in Department of Gastroenterology and Hepatology, Pakistan Medical Research Council, Research Centre, Jinnah Post Graduate Medical Centre, Karachi, from May 2006 to April 2010. Subjects and Methods: Over the period of four years, 186 patients who were found positive for campylobacter like organism test during endoscopy were further tested for anti H. pylori IgG titre before being treated for H. pylori. Patients were given triple therapy comprising of Omeprazole (20 mg twice daily), Amoxicillin (1 gm twice daily) and Clarythromycin (500 mg twice daily) for a week and were followed at 1, 3, 6 and 12 months to check symptomatic relief and they were tested again for H.Pylori antibody titres. Data was collected on pre-designed proforma which included patient's demography, symptoms and diagnosis. Results: Out of 186 patients who had a positive campylobacter like organism test, 173 patients consented to participate in the study. Serology for H.Pylori was positive in 119(68%) cases. A decline in mean antibody titres was observed as 11%, 21.5%, 54.7% and 59.2% at 1, 3, 6 and 12 months respectively. Conclusions: Sensitivity of serology for diagnosing H. pylori infection is good but using these as a tool for monitoring response to treatment is doubtful. A slow drop in H.pylori antibodies was seen over 12 months and therefore, physicians are cautioned not to retreat the already treated cases till about one year post treatment. Policy message: H. pylori antibodies should be checked on regular basis to diagnose new cases but it should not be used in previously treated patients to retreat. (author)

    2015-03-01

    Full Text Available The world debate focused on preserving the environment, such a s that held during the United Nations Conference on Sustainable Development, Rio +20, in conjunction with Brazil’s growing foreign trade requires a study of all these topics in management courses. The central premise of this paper is to investigate the systematization of trade concepts through the use of business games. Two asymmetric scenarios for exporting and importing teams were developed using action research and qualitative data analysis. The longitudinal study was conducted on four separate, sequential classes from the Foreign Trade discipline of two universities from southern Brazilian. The students were able to discuss a variety of foreign trade topics and interact autonomously among themselves using business games that stimulate business negotiations through role playing dynamics, demonstrating that this teaching strategy can be used as a foreign trade teaching support tool. The final proposal was to change the game scenarios to focus on the decision between lowest costs and sustainable manufacturing processes without losing the aspects developed previously. The results showed that students’ decisions are more linked to their prior personal environmental concepts than to competition strategies developed for the company.

    1993-01-01

    On January 4, two months and a day after the Trojan nuclear power reactor survived two ballot initiatives that sought to have the 1095-MWe pressurized water reactor closed immediately, the board of directors of Portland General Electric Company voted to do what those initiatives had wanted done. Trojan went off line on November 9 because of a leak in a steam generator tube. It will not return to service ever again, even though PGE had originally planned to keep running the plant until 1996. The utility announced that immediate closure was now the least-cost choice for ratepayers, mainly because of uncertainty over what would have to be done at the plant to satisfy the Nuclear Regulatory Commission - within which, according to PGE, there was a scientific disagreement over the adequacy of the plant's steam generators to support operation until 1996. PGE has not yet firmed up its decommissioning plan for Trojan. Also, at this writing, there had been no indication whether the absence of Trojan might improve the chances for completion of the region's two mothballed nuclear projects, Washington Public Power Supply System's WNP-1 and -3

    A straightforward generalization of the simple net present value rule that correctly predicts when to invest in two classes of projects that can be delayed is derived. The first class consists of projects for which the option to delay derives its value exclusively from uncertainty about interest rates. It is shown that the optimal rule for investing in such projects is to simply multiply the discount rate of the project by the ratio of the mortgage rate to the riskless rate and then use this ...

  1. Moving in extreme environments: what's extreme and who decides?

    Science.gov (United States)

    Cotter, James David; Tipton, Michael J

    2014-01-01

    Humans work, rest and play in immensely varied extreme environments. The term 'extreme' typically refers to insufficiency or excess of one or more stressors, such as thermal energy or gravity. Individuals' behavioural and physiological capacity to endure and enjoy such environments varies immensely. Adverse effects of acute exposure to these environments are readily identifiable (e.g. heat stroke or bone fracture), whereas adverse effects of chronic exposure (e.g. stress fractures or osteoporosis) may be as important but much less discernable. Modern societies have increasingly sought to protect people from such stressors and, in that way, minimise their adverse effects. Regulations are thus established, and advice is provided on what is 'acceptable' exposure. Examples include work/rest cycles in the heat, hydration regimes, rates of ascent to and duration of stay at altitude and diving depth. While usually valuable and well intentioned, it is important to realise the breadth and importance of limitations associated with such guidelines. Regulations and advisories leave less room for self-determination, learning and perhaps adaptation. Regulations based on stress (e.g. work/rest cycles relative to WBGT) are more practical but less direct than those based on strain (e.g. core temperature), but even the latter can be substantively limited (e.g. by lack of criterion validation and allowance for behavioural regulation in the research on which they are based). Extreme Physiology & Medicine is publishing a series of reviews aimed at critically examining the issues involved with self- versus regulation-controlled human movement acutely and chronically in extreme environments. These papers, arising from a research symposium in 2013, are about the impact of people engaging in such environments and the effect of rules and guidelines on their safety, enjoyment, autonomy and productivity. The reviews will cover occupational heat stress, sporting heat stress, hydration, diving, extreme loading, chronic unloading and high altitude. Ramifications include factors such as health and safety, productivity, enjoyment and autonomy, acute and chronic protection and optimising adaptation.

    Using a different process to clean concentrated waste tanks at the James A. FitzPatrick nuclear power plant in New York saved nearly half million dollars. The plan essentially allowed processing concentrator bottoms as waste sludge (solidification versus dewatering) that could still meet burial ground requirements. The process reduced the volume from 802.2 to 55 cubic feet. This resin throwaway system eliminated chemicals in the radwaste systems and was designed to ease pressure on the pradwaste processing system, reduce waste and improve plant chemistry.

    The Government of the Netherlands recently informed Parliament about a set of additional measured aimed at achieving the Netherlands' climate targets, set in the Second National Environmental Policy Plan of December 1993. These additional measures should be a further guarantee that 3% reduction in CO 2 emissions will be achieved in 2000 compared to 1990 levels. Energy saving in offices and small companies will be further encouraged. Furthermore, two coal-fired power stations will switch fuels to 10% wood. At present the Netherlands has an installed capacity of about 14,000 MW, about one third of which is coal fired. The Netherlands emission inventory will now be created according to the IPCC methodology, except for temperature correction. 3 tabs

For fossil energy systems, gas turbines have emerged as the technology of choice because of their high efficiencies, Already, operating efficiencies of 55% and above in combined-cycle, advanced gas turbines will be achieving 60% thermal efficiency by the end of this decade. With the next generation of gas turbines, there could be combined-cycle efficiencies a few points higher by the year 2010

    Lemoignan, Josée; Ells, Carolyn

    2010-06-01

    Throughout the course of their illness, people with amyotrophic lateral sclerosis (ALS) must make many treatment decisions; however, none has such a significant impact on quality of life and survival as decisions about assisted ventilation. The purpose of this study was to better understand the experience of decision-making about assisted ventilation for ALS patients. Using qualitative phenomenology methodology, 10 semi-structured interviews were conducted with persons with ALS and their caregivers to elicit factors that are pertinent to their decision-making process about assisted ventilation. Six main themes emerged from the interviews. (1) the meaning of the intervention - participants made a sharp distinction between non-invasive ventilation, which they viewed as a means to relieve symptoms of respiratory failure, and invasive ventilation, which they viewed as taking over their breathing and thereby saving their life when they otherwise would die, (2) the importance of context - including functional status, available supports, and financial implications, (3) the importance of values - with respect to communication, relationships, autonomy, life, and quality of life, (4) the effect of fears - particularly respiratory distress, chocking, running out of air, and the process of death itself, (5) the need for information - how use of assisted ventilation would impact daily life, how death from respiratory failure would occur, how caregivers and persons with ALS differ in their information needs and common misconceptions, and (6) adaptation to or acceptance of the intervention - a lengthy process that involved gradual familiarization with the equipment and its benefits. People with ALS and caregivers value autonomy in decision-making about assisted ventilation. Their decision-making process is neither wholly rational nor self-interested, and includes factors that health professionals should anticipate and address. Discussions about assisted ventilation and timing should be tailored to each individual and undertaken periodically.

    Science.gov (United States)

    Pettorossi, Alberto; Proietti, Maurizio; Senni, Valerio

    We present a method based on logic program transformation, for verifying Computation Tree Logic (CTL*) properties of finite state reactive systems. The finite state systems and the CTL* properties we want to verify, are encoded as logic programs on infinite lists. Our verification method consists of two steps. In the first step we transform the logic program that encodes the given system and the given property, into a monadic ω -program, that is, a stratified program defining nullary or unary predicates on infinite lists. This transformation is performed by applying unfold/fold rules that preserve the perfect model of the initial program. In the second step we verify the property of interest by using a proof method for monadic ω-programs.

    Zettler, Patricia J

    2015-01-01

    In addition to being an example of unsubstantiated hype about regenerative medicine, the controversy around the Italy-based Stamina Foundation's unproven stem cell therapy represents another chapter in a continuing debate about how to balance patients' requests for early access to experimental medicines with requirements for demonstrating safety and effectiveness. Compassionate use of the Stamina therapy arguably should not have been permitted under Italy's laws, but public pressure was intense and judges ultimately granted access. One lesson from these events is that expert regulatory agencies may be the institutions most competent to make compassionate use decisions and that policies should include more specific criteria for authorizing compassionate use. But even where regulatory agencies make decisions based on clear rules, difficult questions will arise. PMID:26202382

And so the situation from three years ago is repeating itself - a new financial department of the company is expected to lead the company out of the substantial cash-flow crisis caused by credit burden. This difficulties have been caused by decisions taken by state like building of power plant in Mochovce. Minister Nemcsics will not be in the position to complete his ambition to direct the activities of SE, his successor will need time to find his way and so the solution stays in hands of the company management. Where will they look for the necessary recourses? The operation generates virtually no cash-flow increase - reminds General Manager for Economy and Finances, Milos Sujansky. What the manager considers a possible solution is loan restructuring. 'We have to review the whole loan portfolio in order to eliminate the pressure caused by the necessity to repay the debts in 2004 and the beginning of 2005 and that would allow as to survive in a relatively normal state,' unveils the company plans M. Sujansky. That would mean postponing the instalment payments until 2007. Before this strategy was prepared the existing debts had to be analysed. The results of this analysis showed 'an inconsistent debt portfolio with many non-standard elements anchored in relevant contracts'. In the opinion of Director for External Financing this fact makes the loan management and decision making in regards to assets/liabilities structure difficult. 'When you have 35 different loans and every contract is different - communication and monitoring costs much effort,' he adds. According to an Auditors Report for 2002 prepared according to ISA standards even the share of third-party capital is high and inhomogeneous. The previous financial management managed to minimize the deficit. The fact that for SE a state guarantee became unreachable, the legislation did not allow any increase of energy prices and SE were not allowed to claim penalty payments from privatised power distribution companies in the past - that all deprived the SE from funds that could have been used for refinancing. But, according to I. Lovisek, even if we did not take into account the objective factors, we had to admit that the financing of SE was lacking a systemic approach. Financial managers of SE want to create a new approach towards the banks. 'In August and September we want to initiate 30 meetings in order to set up a bank-club,' unveils I. Lovisek. SE plans to ask them to play an active role in the restructuring process. Depending on attitude of the banks SE plans to select a group of five to six foreign and two to three local banks. But the credit conditions will not be dictated by the banks. The Manager for External Financing of SE stresses that the banks will be preparing their offers based on a detailed plan prepared by SE and SE will then select the best offers. I. Lovisek is positive that this will create a competition between the banks in the club. Banks orientated on commercial risk will be preferred as these will not require state guarantees. But during the time SE will need to build the club it will have to solve its this-year's deficit. Even if this may mean more expensive short-time solutions. 'The simpler the loan structure the better,' he adds. But what will motivate the banks participating in the club? 'All attractive transactions like realization of syndicate, swaps and hedging would be done through these banks,' answers I. Lovisek. Previous management did not succeed in securing a financing that would be advantageous for SE in a long-term run. How can the new management be so sure? 'What the banks expect is an open dialogue about the company's internal problems. We are prepared to lead such a dialogue.' 'And what is more, if you have a strategy prepared the banks are willing to listen,' continues I. Lovisek. In his opinion it is well possible to make the banks to change their attitude towards SE: 'A debtor will be replaced by a partner.' But even this management appeals to the state to solve the SE's claims towards the state and other public entities. (Author)

  15. Decidable and undecidable arithmetic functions in actin filament networks

    Science.gov (United States)

    Schumann, Andrew

    2018-01-01

    The plasmodium of Physarum polycephalum is very sensitive to its environment, and reacts to stimuli with appropriate motions. Both the sensory and motor stages of these reactions are explained by hydrodynamic processes, based on fluid dynamics, with the participation of actin filament networks. This paper is devoted to actin filament networks as a computational medium. The point is that actin filaments, with contributions from many other proteins like myosin, are sensitive to extracellular stimuli (attractants as well as repellents), and appear and disappear at different places in the cell to change aspects of the cell structure—e.g. its shape. By assembling and disassembling actin filaments, some unicellular organisms, like Amoeba proteus, can move in response to various stimuli. As a result, these organisms can be considered a simple reversible logic gate—extracellular signals being its inputs and motions its outputs. In this way, we can implement various logic gates on amoeboid behaviours. These networks can embody arithmetic functions within p-adic valued logic. Furthermore, within these networks we can define the so-called diagonalization for deducing undecidable arithmetic functions.

  16. Is it economically justifiable to decide on nuclear power phaseout?

    International Nuclear Information System (INIS)

    Scholz, L.

    1988-01-01

    The author critically comments on the various expert opinions describing and assessing the economic and other impacts of a nuclear power phaseout. One of his conclusions is that the complexity of the problems involved may lead astray in the public controversy about the nuclear issue, inducing irrational speculations on the one hand, and blue-eyed hopes on the other. This may lead to the dangerous situation that speculations or arbitrary information may be clad with the cloak of (unjustified) assumptions made to look like scientific information. (orig.) [de

  17. Deciding over nature: Corruption and environmental impact assessments

    International Nuclear Information System (INIS)

    Williams, Aled; Dupuy, Kendra

    2017-01-01

    Environmental Impact Assessments (EIAs) are an important analytic tool for identifying and potentially mitigating project risks and negative environmental and societal impacts. Their usefulness, however, depends on how they are implemented and on whether findings are used in public decision-making. Given the notorious vulnerability of public-private interactions to corrupt practices, we examine potential and actual corruption risks across four stages of a generic EIA process. Combined with case analysis of the EIA process in Albania, a Southeastern European context experiencing serious governance challenges, we reflect on the vulnerabilities of EIAs to various forms of corruption from a principal-agent perspective. We concur with earlier research suggesting that the fundamentally rationalist approach behind EIAs do not necessarily match the empirical realities of public environmental decision-making, particularly in less mature EIA systems. We conclude with suggestions for framing a future research agenda in this area and touch on tentative policy remedies.

  18. Comparing and deciding: a historical note on education policy

    2013-07-01

    Full Text Available This article provides a ‘lineage’ of decisions related to education policy which takes comparison as its motive, knowledge and method. A conceptual chain of world system, internationalization, convergence in education and globalization is briefly outlined. The paper examines decision-making in education policy according to agreement, mainstreaming and production criteria, taking Latin America as the linkage and the European Community as the construction. Reasoning and enlightenment are gathered in different fields of history: culture, economics, politics and education. The present paper applies a core structuring epistemology –culled from a variety of academic domains– with comparison and decision underpinning a complex rationale where time, space, materiality, knowledge, ideas, action, and evaluation all intersect.

  2. How to Decide on Modeling Details: Risk and Benefit Assessment.

    Science.gov (United States)

    Özilgen, Mustafa

    Mathematical models based on thermodynamic, kinetic, heat, and mass transfer analysis are central to this chapter. Microbial growth, death, enzyme inactivation models, and the modeling of material properties, including those pertinent to conduction and convection heating, mass transfer, such as diffusion and convective mass transfer, and thermodynamic properties, such as specific heat, enthalpy, and Gibbs free energy of formation and specific chemical exergy are also needed in this task. The origins, simplifying assumptions, and uses of model equations are discussed in this chapter, together with their benefits. The simplified forms of these models are sometimes referred to as "laws," such as "the first law of thermodynamics" or "Fick's second law." Starting to modeling a study with such "laws" without considering the conditions under which they are valid runs the risk of ending up with erronous conclusions. On the other hand, models started with fundamental concepts and simplified with appropriate considerations may offer explanations for the phenomena which may not be obtained just with measurements or unprocessed experimental data. The discussion presented here is strengthened with case studies and references to the literature.

    In small scale societies, lethal attacks on another individual usually invite revenge by the victim's family. We might expect those who perpetrate such attacks to do so only when their own support network (mainly family) is larger than that of the potential victim so as to minimise the risk of retaliation. Using data from Icelandic family sagas, we show that this prediction holds whether we consider biological kin or affinal kin (in-laws): on average, killers had twice as many relatives as th...

    The main limitation of aqueous supercapacitors (SCs) lies in their narrow operating voltages, especially when compared with organic SCs. Fundamental understanding of factors relevant to the operating voltage helps providing guidance for the assembly of high-voltage aqueous SCs. In this regard, this concept analyzes the deciding factors for the operating voltage of aqueous SCs. Strategies applied to expand the operating voltage are summarized and discussed from the aspects of electrolyte, electrode, and asymmetric structure. Dynamic factors associated with water electrolysis and maximally using the available potential ranges of electrodes are particularly emphasized. Finally, other promising approaches that have not been explored and their challenges are also elaborated, hoping to provide more insights for the design of high-voltage aqueous SCs. © 2018 Wiley-VCH Verlag GmbH & Co.

    Acute myeloid leukemia (AML) is predominantly a disease of older patients with a poor long-term survival. Approval of decitabine (DAC) in the European Union (EU) in 2012 for the treatment of patients with AML ≥65 years marks the potential for hypomethylating agents in elderly AML. Nevertheless the situation is dissatisfactory and the quest for novel treatment approaches, including combination epigenetic therapy is actively ongoing. The given randomized trial should be helpful in investigating the question whether combinations of DAC with the histone deacetylase (HDAC) inhibitor valproic acid (VPA) and/or all-trans retinoic acid (ATRA), which in vitro show a very promising synergism, are superior to the DAC monotherapy. The accompanying translational research project will contribute to find surrogate molecular end points for drug efficacy and better tailor epigenetic therapy. An additional aim of the study is to investigate the prognostic value of geriatric assessments for elderly AML patients treated non-intensively. DECIDER is a prospective, randomized, observer blind, parallel group, multicenter, Phase II study with a 2x2 factorial design. The primary endpoint is objective best overall response (complete remission (CR) and partial remission (PR)). The target population is AML patients aged 60 years or older and unfit for standard induction chemotherapy. Patients are randomized to one of the four treatment groups: DAC alone or in combination with VPA or ATRA or with both add-on drugs. One interim safety analysis was planned and carried out with the objective to stop early one or more of the treatment arms in case of an unacceptable death rate. This analysis showed that in all treatment arms the critical stopping rule was not reached. No important safety issues were observed. The Data Monitoring Committee (DMC) recommended continuing the study as planned. The first patient was included in December 2011. A total of 189 out of 200 planned patients were randomized

    A standard procedure for choosing suitable sites for the localization of waste treatment and disposal plants is the main step for a correct sanitary program. Two are the principal difficulties: to define a correct group of criteria, excluding and limiting conditions to be applied in the E.I.A.`s techniques: to employ a simplified and flexible methodology that permits to obtain a suitable sites hierarchy. An E.I.A.`s methodology is proposed, distinguished in three numeric techniques with different complexity. Beside, to limit the subjectiveness of the user`s judgement, two solutions are applied, i.e., a method to define the impact factors of the Plant system and a sensitivity test be applied on the importance range of values. =

    The present study is investigating the effect of high temperature sintering combined with ball milled powders for the preparation of FeSe material via solid state sintering technique. The commercial powders of Fe (99.9% purity) and Se (99.9% purity) were mixed in a nominal ratio Fe:Se = 1:1 and thoroughly ground and ball-milled in a glove box during 6 h. Then, the powder mixture was pressed into pellets of 5 mm in diameter and 2 mm thickness using an uniaxial pressure of 100 MPa. The samples were sealed in quartz tubes and sintered at 600 C for 24 h. Then, the pellets were again thoroughly ground and ball-milled in the glove box and pressed into pellets, and the final sintering was performed at two different temperatures, namely at 900 C for 24 h and at 950 C for 24 h. X-ray diffraction results confirmed that both samples showed mainly of the β-FeSe with tetragonal structure. The temperature dependence of magnetization (M-T) curves revealed a sharp superconducting transition T{sub c,} {sub onset} = 8.16 K for the sample sintered at 900 C. Further, scanning electron microscopy observations proved that samples sintered at 900 C show a platelike grain structure with high density. As a result, improved irreversibility fields around 5 T and the critical current density (J{sub c}) values of 6252 A cm{sup -2} at 5 K and self-field are obtained. Furthermore, the normalized volume pinning force versus the reduced field plots indicated a peak position at 0.4 for the sample sintered at 900 C. Improved flux pinning and the high J{sub c} values are attributed to the textured microstructure of the material, produced by a combination of high temperature sintering and ball milling.

Shall the expression be limited to literal element of work? Can the non-literal element of computer program possibly be categorized as expression? If it is possible, then what is the criterion for drawing such a distinction? Under what kind of circumstances, can the expression be regarded s having been merged with idea? And what is the process to make such a judgment of infringement? In this regard Taiwan judicial decisions have submitted different opinions. Based upon Supreme Court Criminal Judgment No. 94-Tai-Shang-Tze-1530, 2005, this article analyze the criterion for the distinction between idea and expression, and then analyze the contents of the three-step procedure by which judges in Altai applied the principle of the dichotomy and merger between idea and expression to decide the infringement. Finally, in conclusion, this article makes some comments on relevant mentioned above cases, serving as a reference for readers to have a panoramic observation.

    After having recalled the content and purpose of his research thesis, the author proposes a detailed overview of the research works he performed thereafter in the field of the speciation of actinides at the level of the organism entry gates and in target tissues. These works therefore concern four important areas of research in radioprotection: bio-kinetic, toxicology, decorporation, and dosimetry studies. The author outlines how speciation studies can be useful for these different areas, and to better understand and describe, and therefore foresee, the biokinetics and toxicity of radionuclides

  20. Using 3-color chromosome painting to decide between chromosome aberration models

    International Nuclear Information System (INIS)

    Lucas, J.N.; Sachs, R.K.

    1993-01-01

    Ionizing radiation produces chromosome aberrations when DNA double strand breaks (DSB) interact pairwise. For more than 30 years there have been two main, competing theories of such binary DSB interactions. The classical theory asserts that an unrepaired DSB makes two ends which separate, with each end subsequently able to join any similar (non-telomeric) end. The exchange theory asserts that the two DSB ends remain associated until repair or a reciprocal chromosome exchange involving a second DSB occurs. The authors conducted an experiment to test these models, using 3-color chromosome painting. After in vitro irradiation of resting human lymphocytes, they observed cells with three-color triplets at first metaphase: three derivative chromosomes having permuted colors, as if three broken chromosomes had played musical chairs. On the exchange model in its standard form such 3-color triplets cannot occur. On the classical model the expected frequency can be calculated. They report data and computer calculations which exclude the exchange model and favor the classical model

  1. Who decides who has won the bet? Total and Anthropogenic Warming Indices

    2016-12-01

    An extension of the idea of betting markets as a means of revealing opinions about future climate are climate policies indexed to geophysical indicators: for example, to ensure net zero global carbon dioxide emissions by the time anthropogenic warming reaches 1.5 degrees above pre-industrial, given about 1 degree of warming already, emissions must fall, on average, by 20% of their current value for every tenth of a degree of anthropogenic warming from now on. In principle, policies conditioned on some measure of attributable warming are robust to uncertainty in the global climate response: the risk of a higher or lower response than expected is borne by those affected by climate change mitigation policy rather than those affected by climate change impacts, as is the case with emission targets for specific years based on "current understanding" of the response. To implement any indexed policy, or to agree payout terms for any bet on future climate, requires consensus on the definition of the index: how is it calculated, and who is responsible for releasing it? The global mean surface temperature of the current decade relative to pre-industrial may vary by 0.1 degree or more depending on precisely what is measured, what is defined as pre-industrial, and the treatment of regions with sparse data coverage in earlier years. Indices defined using different conventions, however, are all expected to evolve very similarly over the coming decades, so agreeing on a conservative, traceable index such as HadCRUT is more important than debating the "true" global temperature. A more important question is whether indexed policies and betting markets should focus on total warming, including natural and anthropogenic drivers and internal variability, or an Anthropogenic Warming Index (AWI) representing an unbiased estimate of warming attributable to human influence to date. We propose a simple AWI based solely on observed temperatures and global natural and anthropogenic forcing estimates. It is much less volatile than total observed warming, which might discourage participation in betting markets, but would be a substantial advantage for indexed policies. It is also much more relevant to the UNFCCC goal of limiting anthropogenic warming to "well below" 2 degrees. The 2016 value for the AWI will be announced at AGU.

  3. Tuning of electrostatic vs. depletion interaction in deciding the phase behavior of nanoparticle-polymer system

    Nanoparticle-polymer system interestingly show a re-entrant phase behavior where charge stabilized silica nanoparticles (phase I) undergo particle clustering (phase II) and then back to individual particles (phase I) as a function of polymer concentration. Such phase behavior arises as a result of dominance of various interactions (i) nanoparticle-nanoparticle electrostatic repulsion (ii) polymer induced attractive depletion between nanoparticles and (iii) polymer-polymer repulsion, at different concentration regimes. Small-angle neutron scattering (SANS) has been used to study the evolution of interaction during this re-entrant phase behavior of nanoparticles by contrast-marching the polymer. The SANS data have been modeled using a two-Yukawa potential accounting for both attractive and repulsive parts of the interaction between nanoparticles. The degree of both of these parts has been separately tuned by varying the polymer concentration and ionic strength of the solution. Both of these parts are found to have long-range nature. At low polymer concentrations, the electrostatic repulsion dominates over the depletion attraction. The magnitude and the range of the depletion interaction increase with the polymer concentration leading to nanoparticle clustering. At higher polymer concentrations, the increased polymer-polymer repulsion reduces the strength of depletion leading to re-entrant phase behavior. The clusters formed under depletion attraction are found to have surface fractal morphology.

    In pediatric urology, robot-assisted surgery has overcome several impediments of conventional laparoscopy. However, workspace has a major impact on surgical performance. The limited space in an infant can significantly impede the mobility of robotic instruments. There is currently no consensus on which infant can undergo robotic intervention and no parameters to help make this decision, especially for those surgeons at the start of their learning curve. We sought to evaluate our experience with infants to create an objective standard to determine which patients may be most suitable for robotic surgery. We prospectively evaluated 45 infants (24 males, 21 females), aged 3-12 months old, who underwent a robotic intervention for either upper or lower urinary tract pathology. At the preoperative office visit the attending surgeon measured the distance between both anterior superior iliac spines (ASIS) as well as the puboxyphoid distance (PXD), regardless of whether the approach was for upper or lower tract disease. Patients' weights were also noted. During surgery, we recorded the number of robotic collisions as well as console time. All surgeries were performed utilizing the da Vinci Si Surgical System by a single surgeon. There were no differences in ASIS, PXD, collisions or console time when stratified by gender, age or weight. When arranging by upper or lower tract approach, there was no difference in the number of collisions. There was a strong inverse relationship between both ASIS distance and PXD and the number of collisions. Additionally, there was a strong correlation between the number of collisions and console time (Fig. 1). Using a cutoff of 13 cm for the ASIS, there were significantly fewer collisions in the >13 cm group as compared to the ≤13 cm group. This was also true for the PXD using a cutoff of 15 cm: there were significantly fewer collisions in the >15 cm group as compared to the ≤15 cm group. Safe proliferation of robotic technology in the infant population is, in part, dependent on careful patient selection. Our data demonstrated a reduction in instrument collisions and console time with increasing anterior superior iliac spine and puboxyphoid distances. Neither age nor weight was correlated with these measurements, the number of instrument collisions or console time. Limitations include that this is a single institution study with all infants being operated on by a single surgeon. Therefore, the findings of this study may not be generalizable to a less experienced surgeon. Yet, we believe that ASIS and PXD measurements can be used as a guide for the novice surgeon who is beginning to perform robotic-assisted surgery in infants. We found that surgeon ability to perform robotic surgery in an infant is restricted by collisions when the infant has an ASIS measurement of 13 cm or less or a PXD of 15 cm or less. Objective assessment of anterior superior iliac spine and puboxyphoid distance can aid in selecting which infants can safely and efficiently undergo robotic intervention with a minimum of instrument collision, thereby minimizing operative time.

    Full Text Available Production planning includes push, pull and hybrid production systems that production firms determine their production strategies according to many variables before starting production. The administration of this process requires experience and time. The intensity of rivalry makes this kind of decision processes important, because no firm has the luxury to waste time and to make a wrong decision. In order to solve this problem, research proposes to use integrated decision-making trial and evaluation laboratory (DEMATEL and analytic network process (ANP together which are methods of multi-criteria decision-making models. The process being used to establish which options are found to be most acceptable for operations managers has been demonstrated how applicable it is by using the generated model in automotive industry.

  8. Predicting, deciding, learning: can one evaluate the 'success' of national climate scenarios?

    Hulme, Mike; Dessai, Suraje

    2008-01-01

    Scenarios may be understood as products and/or processes. Viewing scenario exercises as productive tends to emphasize their tangibility: scenario products may acquire value unrelated to the processes of their creation. Viewing scenario exercises as procedural tends to emphasize their modes of formation: the process of constructing scenarios may have benefits irrespective of the value of ensuing products. These two framings yield different expectations about how one might evaluate the 'success' or otherwise of scenario exercises. We illustrate three approaches to evaluating the success or otherwise of scenarios using the example of the series of national UK climate scenarios published between 1991 and 2002. These are: predictive success (has the future turned out as envisaged?), decision success (have 'good' decisions subsequently been made?) and learning success (have scenarios proved engaging and enabled learning?). We reflect on the different ways the 'success' of national climate scenarios might be evaluated and on the relationship between the productive and procedural dimensions of scenario exercises.

    In the event of the total dismantling of a nuclear power station, a decision has to be reached as to whether large masses of material should and/or can be decontaminated to such a degree that they can subsequently be recycled or taken to a public refuse dump without being subject to radiological protection regulations. Technical, legal and economic aspects have to be taken into account in such a decision. The estimated costs for the final storage of radioactive waste range from DM 4 000 to DM 6 200 per Mg of net mass, depending on the type of final storage. In the Federal Republic of Germany, 50 Mg of steel scrap and 30 Mg of brass have already been decontaminated and melted down as part of the re-equipping of Wurgassen nuclear power station. (author)

  11. Beyond Sexist Beliefs: How Do People Decide to Use Gender-Inclusive Language?

    Science.gov (United States)

    Sczesny, Sabine; Moser, Franziska; Wood, Wendy

    2015-07-01

    When people use generic masculine language instead of more gender-inclusive forms, they communicate gender stereotypes and sometimes exclusion of women from certain social roles. Past research related gender-inclusive language use to sexist beliefs and attitudes. Given that this aspect of language use may be transparent to users, it is unclear whether people explicitly act on these beliefs when using gender-exclusive language forms or whether these are more implicit, habitual patterns. In two studies with German-speaking participants, we showed that spontaneous use of gender-inclusive personal nouns is guided by explicitly favorable intentions as well as habitual processes involving past use of such language. Further indicating the joint influence of deliberate and habitual processes, Study 2 revealed that language-use intentions are embedded in explicit sexist ideologies. As anticipated in our decision-making model, the effects of sexist beliefs on language emerged through deliberate mechanisms involving attitudes and intentions. © 2015 by the Society for Personality and Social Psychology, Inc.

    Research suggests that desired family involvement (FI) in medical decision making may depend on cultural values. Unfortunately, the field lacks cross-cultural studies that test this assumption. As a result, providers may be guided by incomplete information or cultural biases rather than patient preferences. Researchers developed 6 culturally relevant disease scenarios varying from low to high medical seriousness. Quota samples of approximately 290 middle-aged urban residents in Australia, China, Malaysia, India, South Korea, Thailand, and the USA completed an online survey that examined desired levels of FI and identified individual difference predictors in each country. All reliability coefficients were acceptable. Regression models met standard assumptions. The strongest finding across all 7 countries was that those who desired higher self-involvement (SI) in medical decision making also wanted lower FI. On the other hand, respondents who valued relational-interdependence tended to want their families involved - a key finding in 5 of 7 countries. In addition, in 4 of 7 countries, respondents who valued social hierarchy desired higher FI. Other antecedents were less consistent. These results suggest that it is important for health providers to avoid East-West cultural stereotypes. There are meaningful numbers of patients in all 7 countries who want to be individually involved and those individuals tend to prefer lower FI. On the other hand, more interdependent patients are likely to want families involved in many of the countries studied. Thus, individual differences within culture appear to be important in predicting whether a patient desires FI. For this reason, avoiding culture-based assumptions about desired FI during medical decision making is central to providing more effective patient centered care.

  15. Bose-Einstein condensates form in heuristics learned by ciliates deciding to signal 'social' commitments.

    Clark, Kevin B

    2010-03-01

    Fringe quantum biology theories often adopt the concept of Bose-Einstein condensation when explaining how consciousness, emotion, perception, learning, and reasoning emerge from operations of intact animal nervous systems and other computational media. However, controversial empirical evidence and mathematical formalism concerning decoherence rates of bioprocesses keep these frameworks from satisfactorily accounting for the physical nature of cognitive-like events. This study, inspired by the discovery that preferential attachment rules computed by complex technological networks obey Bose-Einstein statistics, is the first rigorous attempt to examine whether analogues of Bose-Einstein condensation precipitate learned decision making in live biological systems as bioenergetics optimization predicts. By exploiting the ciliate Spirostomum ambiguum's capacity to learn and store behavioral strategies advertising mating availability into heuristics of topologically invariant computational networks, three distinct phases of strategy use were found to map onto statistical distributions described by Bose-Einstein, Fermi-Dirac, and classical Maxwell-Boltzmann behavior. Ciliates that sensitized or habituated signaling patterns to emit brief periods of either deceptive 'harder-to-get' or altruistic 'easier-to-get' serial escape reactions began testing condensed on initially perceived fittest 'courting' solutions. When these ciliates switched from their first strategy choices, Bose-Einstein condensation of strategy use abruptly dissipated into a Maxwell-Boltzmann computational phase no longer dominated by a single fittest strategy. Recursive trial-and-error strategy searches annealed strategy use back into a condensed phase consistent with performance optimization. 'Social' decisions performed by ciliates showing no nonassociative learning were largely governed by Fermi-Dirac statistics, resulting in degenerate distributions of strategy choices. These findings corroborate previous work demonstrating ciliates with improving expertise search grouped 'courting' assurances at quantum efficiencies and verify efficient processing by primitive 'social' intelligences involves network forms of Bose-Einstein condensation coupled to preceding thermodynamic-sensitive computational phases. 2009 Elsevier Ireland Ltd.

    2005-05-01

    This experiment examined the effect of video-game violence on cooperative decision making. Participants (N= 48) were randomly assigned to play either a violent or a nonviolent version of the video game Doom in dyads. Following the video-game task, participants were separated and given an opportunity to choose to cooperate with their partner for mutual gain, withdraw from the interaction, or exploit their partner for their own benefit. Participants in the violent condition were significantly more likely to choose to exploit their partners than participants in the nonviolent condition. These findings suggest that playing violent video games may undermine prosocial motivation and promote exploitive behavior in social interactions.

    Defining what is appropriate or inappropriate with respect to CT scanning is challenging. There are a variety of influences on scan utilization in children, some more widely recognized and acknowledged than others. It is important to understand the contribution of these elements as we move toward improved utilization. This must be through partnerships and shared efforts and accountability. These efforts include improved resources such as consensus appropriateness criteria and guidelines including decision rules and support. But there also need to be trench-based strategies on the part of practicing radiologists to model cooperative behavior rather than blame-centered behavior. (orig.)

    Women experiencing miscarriage are offered a choice of different treatments to terminate their wanted pregnancy at a time when they are often shocked and distressed. Women's and healthcare professionals' experiences of the decision-making process are not well described. We aimed to gain insight into this process and the circumstances that may affect it. A qualitative study using a grounded theory approach. Data were obtained through semi-structured interviews with six women who had chosen and completed either surgical, medical or expectant treatment for miscarriage and five healthcare professionals involved in the decision-making at an emergency gynaecological department in Denmark. An inductive explorative method was chosen due to limited knowledge about the decision-making process, and a theoretical perspective was not applied until the final analysis. Despite information and pretreatment counselling, choice of treatment was often determined by unspoken emotional considerations, including fear of seeing the foetus or fear of anaesthesia. These considerations were not discussed during the decision-making process, which was a time when the women were under time pressure and experienced emotional distress. Healthcare professionals did not explore women's considerations for choosing a particular treatment and prioritised information differently. We found theory about coping and decision-making in stressful situations useful in increasing our understanding of the women's reactions. In relation to theory about informed consent, our findings suggest that women need more understanding of the treatments before making a decision. This study is limited due to a small sample size, but it generates important findings that need to be examined in a larger sample. Frequently, women did not use information provided about treatment pros and cons in their decision-making process. Because of unspoken thoughts, and women's needs being unexplored by healthcare professionals, information did not target women's needs and their reasoning remained unapparent. © 2014 Nordic College of Caring Science.

  3. Deciding to Change: One District’s Quest to Improve Overall Student Performance

    2007-07-01

    Full Text Available This single case study of a school district responding to federal and state accountability pressures presents a rare analysis of educational decision making as it happens. It focuses in particular on the challenges and choices of making a strategic decision and the transition from that decision into implementation. Using a conceptual framework of multiple stakeholder decision making and a mixed methodology, this article demonstrates who has influence in decision making, how that influence directs decision making, and the effects of the ways in which strategic change decisions are communicated. This particular school district formulated its change decision collaboratively but issued an implementation directive to the schools that was hierarchical in nature. The result is rapid implementation with some unresolved problems. Practical implications suggest that education leaders can be thoughtful about aligning transition choices with desired outcomes. Research implications lead to further examination of implementation consequences stemming from transition choices.

  4. The Canadian experience: why Canada decided against an upper limit for cholesterol.

    Science.gov (United States)

    McDonald, Bruce E

    2004-12-01

    Canada, like the United States, held a "consensus conference on cholesterol" in 1988. Although the final report of the consensus panel recommended that total dietary fat not exceed 30 percent and saturated fat not exceed 10 percent of total energy intake, it did not specify an upper limit for dietary cholesterol. Similarly, the 1990, Health Canada publication "Nutrition Recommendations: The Report of the Scientific Review Committee" specified upper limits for total and saturated fat in the diet but did not specify an upper limit for cholesterol. Canada's Guidelines for Healthy Eating, a companion publication from Health Canada, suggested that Canadians "choose low-fat dairy products, lean meats, and foods prepared with little or no fat" while enjoying "a variety of foods." Many factors contributed to this position but a primary element was the belief that total dietary fat and saturated fat were primary dietary determinants of serum total and low-density lipoprotein (LDL) cholesterol levels, not dietary cholesterol. Hence, Canadian health authorities focused on reducing saturated fat and trans fats in the Canadian diet to help lower blood cholesterol levels rather than focusing on limiting dietary cholesterol. In an effort to allay consumer concern with the premise that blood cholesterol level is linked to dietary cholesterol, organizations such as the Canadian Egg Marketing Agency (CEMA) reminded health professionals, including registered dietitians, family physicians and nutrition educators, of the extensive data showing that there is little relationship between dietary cholesterol intake and cardiovascular mortality. In addition, it was pointed out that for most healthy individuals, endogenous synthesis of cholesterol by the liver adjusts to the level of dietary cholesterol intake. Educating health professionals about the relatively weak association between dietary cholesterol and the relatively strong association between serum cholesterol and saturated fat and trans fats helped keep consumers informed about healthy diets and ways to control blood cholesterol.

  5. Bell's theorem and the problem of decidability between the views of Einstein and Bohr.

    Hess, K; Philipp, W

    2001-12-04

    Einstein, Podolsky, and Rosen (EPR) have designed a gedanken experiment that suggested a theory that was more complete than quantum mechanics. The EPR design was later realized in various forms, with experimental results close to the quantum mechanical prediction. The experimental results by themselves have no bearing on the EPR claim that quantum mechanics must be incomplete nor on the existence of hidden parameters. However, the well known inequalities of Bell are based on the assumption that local hidden parameters exist and, when combined with conflicting experimental results, do appear to prove that local hidden parameters cannot exist. This fact leaves only instantaneous actions at a distance (called "spooky" by Einstein) to explain the experiments. The Bell inequalities are based on a mathematical model of the EPR experiments. They have no experimental confirmation, because they contradict the results of all EPR experiments. In addition to the assumption that hidden parameters exist, Bell tacitly makes a variety of other assumptions; for instance, he assumes that the hidden parameters are governed by a single probability measure independent of the analyzer settings. We argue that the mathematical model of Bell excludes a large set of local hidden variables and a large variety of probability densities. Our set of local hidden variables includes time-like correlated parameters and a generalized probability density. We prove that our extended space of local hidden variables does permit derivation of the quantum result and is consistent with all known experiments.

    The choice of treatment in adult skeletal Class III occlusions often poses a particularly tricky problem for the orthodontist. Faced with the option of either orthodontic camouflage or orthognathic surgery, the clinician's clinical experience is of paramount importance, especially in borderline cases. The aim of our study was to uncover a guide model enabling the practitioner to distinguish between skeletal Class III cases which can be suitably treated with orthodontics and those requiring orthognathic surgery. The lateral headfilms of 47 adult patients exhibiting skeletal Class III occlusions were analyzed. The orthodontic group comprised 22 patients and the surgical group 25. Twenty-seven linear, proportional and angular measurements were scrutinized. Stepwise discriminant analysis was used to identify the dentoskeletal and esthetic variables which most distinguished the two groups. The Holdaway angle was chosen to differentiate between patients prior to treatment. This model enables us to classify 87.2% of patients correctly. Copyright © 2011 CEO.

  8. Deciding to Wait: Partnership Status, Economic Conditions, and Pregnancy during the Great Recession

    2017-02-01

    Full Text Available The Great Recession was associated with reduced fertility in the United States. Many questions about the dynamics underlying this reduction remain unanswered, however, including whether reduced fertility rates were driven by decreases in intended or unplanned pregnancies. Using restricted data from the 2006–2010 National Survey of Family Growth (N = 4,630, we exploit variation in state economic indicators to assess the impact of economic conditions on the likelihood of an intended pregnancy, an unplanned pregnancy, or no pregnancy for adult women without a college education. We focus on variations by partnership and marital status. Overall, we find that worse economic conditions were predictive of a lower risk of unplanned pregnancy. Women's odds of intended pregnancy did not, however, respond uniformly to economic conditions but varied by marital status. When economic conditions were poor, married women had lower odds of intended pregnancy, whereas cohabiting women had greater odds of intended pregnancy.

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

    Science.gov (United States)

    Edwards, Kyle T

    2014-07-01

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

  10. Factors Which Influence Owners When Deciding to Use Chemotherapy in Terminally Ill Pets

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available Chemotherapy is a commonly integrated treatment option within human and animal oncology regimes. Limited research has investigated pet owners’ treatment decision-making in animals diagnosed with malignant neoplasia. Dog and cat owners were asked to complete an online questionnaire to elucidate factors which are key to the decision making process. Seventy-eight respondents completed the questionnaire in full. Fifty-eight percent of pet owners would not elect to treat pets with chemotherapy due to the negative impact of the associated side effects. Seventytwo percent of respondents over estimated pet survival time post chemotherapy, indicating a general perception that it would lead to remission or a cure. Vomiting was considered an acceptable side effect but inappetence, weight loss and depression were considered unacceptable. Owners did expect animals’ to be less active, sleep more and play less, but common side effects were not rated as acceptable despite the potential benefits of chemotherapy. Based on the results, veterinary teams involved with oncology consultations should establish if clients have prior experience of cancer treatments and their expectations of survival time. Quality of life assessments should also be implemented during initial oncology consultations and conducted regularly during chemotherapy courses to inform client decision making and to safe guard animal welfare.

    Aim. Callus is a risk factor, leading to severe diabetic foot ulcer; thus, prevention of callus formation is important. However, normal stress (pressure) and shear stress associated with callus have not been clarified. Additionally, as new valuables, a shear stress-normal stress (pressure) ratio (SPR) was examined. The purpose was to clarify the external force associated with callus formation in patients with diabetic neuropathy. Methods. The external force of the 1st, 2nd, and 5th metatarsal head (MTH) as callus predilection regions was measured. The SPR was calculated by dividing shear stress by normal stress (pressure), concretely, peak values (SPR-p) and time integral values (SPR-i). The optimal cut-off point was determined. Results. Callus formation region of the 1st and 2nd MTH had high SPR-i rather than noncallus formation region. The cut-off value of the 1st MTH was 0.60 and the 2nd MTH was 0.50. For the 5th MTH, variables pertaining to the external forces could not be determined to be indicators of callus formation because of low accuracy. Conclusions. The callus formation cut-off values of the 1st and 2nd MTH were clarified. In the future, it will be necessary to confirm the effect of using appropriate footwear and gait training on lowering SPR-i.

    Brain metastases are common in cancer patients and cause considerable morbidity and mortality. For patients with limited disease and good performance status, treatment typically involves a combination of focal measures (e.g., surgical resection or radiosurgery) for the radiographically apparent disease, followed by adjuvant whole brain radiotherapy (WBRT) to treat subclinical disease. Because of concerns regarding the toxicity of WBRT, especially neurocognitive deterioration, many have advocated withholding adjuvant WBRT. Recently published studies have shed more light on the efficacy of adjuvant WBRT and the neurocognitive effects of WBRT. However, the inclusion of neurocognitive and quality-of-life data in clinical trials are still required to better define the role of adjuvant WBRT. Currently, two Phase III trials are underway, one in Europe and one in North America, that will determine the effect of adjuvant WBRT on patients' quality of life, neurocognitive function, and survival.

The past decade has seen a surge in the availability of alternatives for patients and surgeons in terms of both surgical and nonsurgical options for the management of refractive errors. Newer generation contact lenses provide enhanced safety and better handling, whereas modern-day refractive surgery presents a plethora of choices based on the clinical characteristics and requirements of patients. We have moved from an era of "one size fits all" to a purely customized way of treating patients with refractive errors. This review presents the background, advantages, and disadvantages of the two most commonly used options for correction of ametropia, ie, contact lenses and refractive surgery.

  14. Teaching Computational Thinking: Deciding to Take Small Steps in a Curriculum

    While computational thinking and reasoning are not necessarily the same as computer programming, programs such as MATLAB can provide the medium through which the logical and computational thinking at the foundation of science can be taught, learned, and experienced. And while math and computer anxiety are often discussed as critical obstacles to students' progress in their geoscience curriculum, it is here suggested that an unfamiliarity with the computational and logical reasoning is what poses a first stumbling block, in addition to the hurdle of expending the effort to learn how to translate a computational problem into the appropriate computer syntax in order to achieve the intended results. Because computational thinking is so vital for all fields, there is a need to initiate many and to build support in the curriculum for it. This presentation focuses on elements to bring into the teaching of computational thinking that are intended as additions to learning MATLAB programming as a basic tool. Such elements include: highlighting a key concept, discussing a basic geoscience problem where the concept would show up, having the student draw or outline a sketch of what they think an operation needs to do in order to perform a desired result, and then finding the relevant syntax to work with. This iterative pedagogy simulates what someone with more experience in programming does, so it discloses the thinking process in the black box of a result. Intended as only a very early stage introduction, advanced applications would need to be developed as students go through an academic program. The objective would be to expose and introduce computational thinking to majors and non-majors and to alleviate some of the math and computer anxiety so that students would choose to advance on with programming or modeling, whether it is built into a 4-year curriculum or not.

    Full Text Available Bethany J Russell, Alicia M WardSouthern Adelaide Palliative Services, Repatriation General Hospital, Daw Park, SA, AustraliaAbstract: Communicating effectively with patients who have advanced cancer is one of the greatest challenges facing physicians today. Whilst guiding the patient through complex diagnostic and staging techniques, treatment regimens and trials, the physician must translate often imprecise or conflicting data into meaningful personalized information that empowers the patient to make decisions about their life and body. This requires understanding, compassion, patience, and skill. This narrative literature review explores current communication practices, information preferences of oncology patients and their families, and communication strategies that may assist in these delicate interactions. Overwhelmingly, the literature suggests that whilst the majority of patients with advanced cancer do want to know their diagnosis and receive detailed prognostic information, this varies not only between individuals but also for a given individual over time. Barriers to the delivery and understanding of information exist on both sides of the physician–patient relationship, and family dynamics are also influential. Despite identifiable trends, the information preferences of a particular patient cannot be reliably predicted by demographic, cultural, or cancer-specific factors. Therefore, our primary recommendation is that the physician regularly asks the patient what information they would like to know, who else should be given the information and be involved in decision making, and how that information should be presented.Keywords: metastatic, communication, prognosis, physician–patient relations

  17. Quitting time: When do honey bee foragers decide to stop foraging on natural resources?

    Full Text Available Honey bee foragers may use both personal and social information when making decisions about when to visit resources. In particular, foragers may stop foraging at resources when their own experience indicates declining resource quality, or when social information, namely the delay to being able to unload nectar to receiver bees, indicates that the colony has little need for the particular resource being collected. Here we test the relative importance of these two factors in a natural setting, where colonies are using many dynamically changing resources. We recorded detailed foraging histories of individually marked bees, and identified when they appeared to abandon any resources (such as flower patches that they had previously been collecting from consistently. As in previous studies, we recorded duration of trophallaxis events (unloading nectar to receiver bees as a proxy for resource quality and the delays before returning foragers started trophallaxis as a proxy for social need for the resource. If these proxy measures accurately reflect changes in resource quality and social need, they should predict whether bees continue foraging or not. However, neither factor predicted when individuals stopped foraging on a particular resource, nor did they explain changes in colony-level foraging activity. This may indicate that other, as yet unstudied processes also affect individual decisions to abandon particular resources.

  18. PACAP decides neuronal laminar fate via PKA signaling in the developing cerebral cortex

    2008-01-01

    Laminar formation in the developing cerebral cortex requires the precisely regulated generation of phenotype-specified neurons. To test the possible involvement of pituitary adenylate cyclase-activating polypeptide (PACAP) in this formation, we investigated the effects of PACAP administered into the telencephalic ventricular space of 13.5-day-old mouse embryos. PACAP partially inhibited the proliferation of cortical progenitors and altered the position and gene-expression profiles of newly generated neurons otherwise expected for layer IV to those of neurons for the deeper layers, V and VI, of the cerebral cortex. The former and latter effects were seen only when the parent progenitor cells were exposed to PACAP in the later and in earlier G1 phase, respectively; and these effects were suppressed by co-treatment with a protein kinase A (PKA) inhibitor. These observations suggest that PACAP participates in the processes forming the neuronal laminas in the developing cortex via the intracellular PKA pathway

    Social marketing (SM) campaigns can be a powerful disease prevention and health promotion strategy but health-related campaigns may simply focus on the "promotions" communication activities and exclude other key characteristics of the SM approach. This paper describes the application of a checklist for identifying which lifestyle-related chronic disease prevention campaigns reported as SM actually represent key SM principles and practice. A checklist of SM criteria was developed, reviewed and refined by SM and mass media campaign experts. Papers identified in searches for "social marketing" and "mass media" for obesity, diet and physical activity campaigns in the health literature were classified using the checklist. Using the checklist, 66.6% of papers identified in the "SM" search and 39% of papers identified from the "mass media" search were classified as SM campaigns. Inter-rater agreement for classification using the abstract only was 92.1%. Health-related campaigns that self-identify as "social marketing" or "mass media" may not include the key characteristics of a SM approach. Published literature can provide useful guidance for developing and evaluating health-related SM campaigns, but health promotion professionals need to be able to identify what actually comprises SM in practice. SO WHAT?: SM could be a valuable strategy in comprehensive health promotion interventions, but it is often difficult for non-experts to identify published campaigns that represent a true SM approach. This paper describes the application of a checklist to assist policy makers and practitioners in appraising evidence from campaigns reflecting actual SM in practice. The checklist could also guide reporting on SM campaigns. © 2017 Australian Health Promotion Association.

    Assessment and decision-making in child maltreatment cases is difficult. Practitioners face many uncertainties and obstacles during their assessment and decision-making process. Research exhibits shortcomings in this decision-making process. The purpose of this literature review is to identify and discuss methods to overcome these shortcomings. We conducted a systematic review of the published literature on decision-making using PsychINFO and MEDLINE from 2000 through May 2014. We included reviews and quantitative research studies that investigated methods aimed at improving professional decision-making on child abuse and neglect in child welfare and child protection. Although many researchers have published articles on decision-making including ideas and theories to improve professional decision-making, empirical research on these improvements is scarce. Available studies have shown promising results. Structured decision-making has created a greater child-centred and holistic approach that takes the child's family and environment into account, which has made practitioners work more systematically and improved the analysis of complex situations. However, this approach has not improved inter-rater agreement on decisions made. Shared decision-making may improve the participation of parents and children and the quality of decisions by taking client treatment preferences into account in addition to scientific evidence and clinical experience. A number of interesting developments appear in recent research literature; however, child welfare and child protection must find additional inspiration from other areas, e.g., mental health services, because research on decision-making processes in child welfare and child protection is still rare.

  5. Who decides? The decision-making process of juvenile judges concerning minors with mental disorders.

    2016-01-01

    Previous research on juvenile judges' decision-making process has neglected the role of the different actors involved in judicial procedures. The decision can be considered as a result of information exchange between the different actors involved. The process of making a decision is equally important as the decision itself, especially when the decision considers minors with mental disorders. The presence and the type of interaction determine the information available to the juvenile judges to make their final decision. The overall aim of this study is to gain insight into the role of all actors, including the juvenile judge, in the juvenile judge's decision-making process in cases relating to minors with mental disorders. Semi-structured interviews were carried out with professional actors (n=32), minors (n=31) and parents (n=17). The findings indicated that the judge's decision is overall the result of an interaction between the juvenile judge, the social services investigator and the youth psychiatrist. The other professional actors, the minors and the parents had only a limited role in the decision-making process. The research concludes that the judge's decision-making process should be based on dialogue, and requires enhanced collaboration between the juvenile court and youth psychiatrists from mental health services. Future decision-making research should pay more attention to the interactions of the actors that guide a juvenile judge's decision. Copyright © 2016 Elsevier Ltd. All rights reserved.

  6. "Only God decides": young children's perceptions of divorce and the legal system.

    Pruett, K D; Pruett, M K

    1999-12-01

    To describe research on perceptions of children aged 6 and younger from 21 families of their parents' divorce, of its impact on their families, and of legal officials. Semistructured play interviews were conducted during home visits as parents were conjointly interviewed as part of a larger study on divorce in legal context. Children had much mis-information about divorce as an event and process. What they did know was often inappropriate, frightening, and confusing. They resented how the process "ruined their parents' being friends any more" and proposed reforms based on their wishes and observations. Greater awareness is needed of the child's desire to be heard during the process, to feel safe and less lonely, and to stay in touch with both parents and extended families. Age-appropriate explanations of psychological and legal aspects of the divorce process are likely to support children's positive adjustment and mental health.

  7. Deciding which chemical mixtures risk assessment methods work best for what mixtures

    Teuschler, Linda K.

    2007-01-01

    The most commonly used chemical mixtures risk assessment methods involve simple notions of additivity and toxicological similarity. Newer methods are emerging in response to the complexities of chemical mixture exposures and effects. Factors based on both science and policy drive decisions regarding whether to conduct a chemical mixtures risk assessment and, if so, which methods to employ. Scientific considerations are based on positive evidence of joint toxic action, elevated human exposure conditions or the potential for significant impacts on human health. Policy issues include legislative drivers that may mandate action even though adequate toxicity data on a specific mixture may not be available and risk assessment goals that impact the choice of risk assessment method to obtain the amount of health protection desired. This paper discusses three important concepts used to choose among available approaches for conducting a chemical mixtures risk assessment: (1) additive joint toxic action of mixture components; (2) toxicological interactions of mixture components; and (3) chemical composition of complex mixtures. It is proposed that scientific support for basic assumptions used in chemical mixtures risk assessment should be developed by expert panels, risk assessment methods experts, and laboratory toxicologists. This is imperative to further develop and refine quantitative methods and provide guidance on their appropriate applications. Risk assessors need scientific support for chemical mixtures risk assessment methods in the form of toxicological data on joint toxic action for high priority mixtures, statistical methods for analyzing dose-response for mixtures, and toxicological and statistical criteria for determining sufficient similarity of complex mixtures

  8. What if consumers decided to all ‘go green’? Environmental rebound effects from consumption decisions

    International Nuclear Information System (INIS)

    Murray, Cameron K.

    2013-01-01

    Shifting consumer preferences towards ‘green’ consumption is promoted by many governments and environmental groups. Rebound effects, which reduce the effectiveness of such actions, are estimated for cost-saving ‘green’ consumption choices using Australian data. Cases examined are: reduced vehicle use, reduced electricity use, changing to smaller passenger vehicles, and utilising fluorescent lighting. It is found that if rebound effects are ignored when evaluating ‘green’ consumption, environmental benefits will be overstated by around 20% for reduced vehicle use, and 7% for reduced electricity use. Rebound effects are higher, and environmental benefits lower, when more efficient vehicles or lighting are utilised rather than simple conservation actions of forgoing use. In addition, lower income households have higher rebound effects, suggesting that environmental policy directed at changing consumer behaviour is most effective when targeted at high income households. An inherent trade-off between economic and environmental benefits of ‘green’ consumption choices is demonstrated. The size of the rebound effect, and the observed variation with household income, is attributed to Life-Cycle Analysis (LCA) methodologies associated with the calculation of embodied GHG emissions of consumption goods. These results should be therefore be interpreted as the minimum rebound effect to include in policy evaluation. - Highlights: ► Rebound effects are estimated for cost-saving ‘green’ consumption choices. ► Household demand model utilised with LCA embodied GHG emissions data. ► Rebound effects are 4–24% for electricity and motor fuel conservation. ► Rebound effect declines with household income, increases with more cost savings. ► Conservation choices better than replacing household capital

    Young children demonstrate awareness of normativity in various domains of social learning. It is unclear, however, whether children recognize that rules can be changed in certain contexts and by certain people or groups. Across three studies, we provided empirical evidence that children consider individual authority and collective agreement when reasoning about who can change rules. In Study 1, children aged 4-7years watched videos of children playing simply sorting and stacking games in groups or alone. Across conditions, the group game was initiated (a) by one child, (b) by collaborative agreement, or (c) by an adult authority figure. In the group games with a rule initiated by one child, children attributed ability to change rules only to that individual and not his or her friends, and they mentioned ownership and authority in their explanations. When the rule was initiated collaboratively, older children said that no individual could change the rule, whereas younger children said that either individual could do so. When an adult initiated the rule, children stated that only the adult could change it. In contrast, children always endorsed a child's decision to change his or her own solitary rule and never endorsed any child's ability to change moral and conventional rules in daily life. Age differences corresponded to beliefs about friendship and agreement in peer play (Study 2) and disappeared when the decision process behind and normative force of collaboratively initiated rules were clarified (Study 3). These results show important connections between normativity and considerations of authority and collaboration during early childhood. Copyright © 2017 Elsevier Inc. All rights reserved.

    Quinton, John; Stevens, Carly

    2010-05-01

    Pollution swapping occurs when a mitigation option introduced to reduce one pollutant results in an increase in a different pollutant. Although the concept of pollution swapping is widely understood it has received little attention in research and policy design. This study investigated diffuse pollution mitigation options applied in combinable crop systems. They are: cover crops, residue management, no-tillage, riparian buffer zones, contour grass strips and constructed wetlands. A wide range of water and atmospheric pollutants were considered, including nitrogen, phosphorus, carbon and sulphur. It is clear from this investigation that there is no single mitigation option that will reduce all pollutants and in this poster we consider how choices may be made between mitigation measures which may have a positive effect on one pollutant but a negative effect on another.

  15. Motivating California organic farmers to go solar: Economics may trump philosophy in deciding to adopt photovoltaics

    Science.gov (United States)

    Fata, Johnathon A.

    Organic farmers who have adopted solar photovoltaic (PV) systems to generate electricity are leaders in agricultural energy sustainability, yet research on their culture and motivations is largely incomplete. These farmers share economic and logistical constraints, but they may differ in their underlying worldviews. To better understand what motivates San Francisco Bay Area organic farmers to install solar PV systems, 14 in-depth interviews and short surveys were conducted and included a "frontier mentality" rubric. Additionally, nine online surveys were administered. In this study's sample, financial concerns turned out to provide the greatest motivation for farmers to adopt solar PV. Concern for the environment followed closely. Among farms that did not have solar, the overwhelming prohibiting factor was upfront cost. Climate change was not cited directly as a driving force for adoption of solar PV by any of the participants. A wide range of differences among organic farmers existed in environmental attitudes. This reflected the diversity of views held by organic farmers in California today. For example, certified organic farmers had less strongly held environmental values than did those that eschew third-party certification in favor of a trust-based connection to the consumer. Understanding this group of highly involved environmental players provides insight into environmental behavior of other farmers as well as broader categories of consumers and businesses.

    2015-11-27

    The upper-east and northern regions of Ghana offers a unique opportunity to study the influence of evolutionary social dynamics in making cooperation possible, despite cultural differences. These regions are occupied by several distinct ethnic groups, in interaction, such as the Kussasi, Mamprusi, Bimoba, Konkomba, and Fulani. We will report our fieldwork related to how cooperation takes places there, both within each group and among people from the different groups. Methods included personal networks of cooperation (ego networks), interviews and analysis of group contexts. The most important result is that, while each ethnic group may differ in terms of family and clan structure, a similar pattern can be found in all of them, of cooperation structured around small groups of trust-based close relationships. The study suggests that habitual decisions about cooperation are not strategic or self-interested, but instead are based on unconscious processes sustained by the emotional bonds of trust. These kind of emotional bonds are claimed to be relevant from an evolutionary point of view.

  1. How would you decide? Helping geoscience students consider ethical dimensions in a gescience context

    Science.gov (United States)

    Bank, C. G.; Ryan, A. M.

    2017-12-01

    This presentation shows an example of infusing ethics into geoscience teaching, and a preliminary analysis of student answers to an exam question to establish whether this example can be used in an effective way. We presented a case study on floods in two distribution geoscience courses, and provided students with criteria to come to an ethical decision. One course was taught in winter 2016 and the other in summer 2016 with a total of 358 students. Pre- and post-questionnaires allow only limited conclusions because just 33 students answered both. In the exam we asked students if they would evacuate a small aboriginal settlement to prevent flooding in a large city. We coded their answers according to the criteria (stakeholders, contributions by geoscientists, alternative options, and assumptions) they were provided in class. While students did well listing stakeholders and recalling contributions by geoscientists they struggled to provide alternative options. Still, many of them verbalized assumptions inherent in their thoughts and nearly half of students recognized that this is a complex problem. We posit that a case study is a valid way to encourage students to link ethics to a geoscience issue, and propose that our framework may empower geoscience educators who do not necessarily feel comfortable teaching ethics to add this element to their teaching toolkit.

  2. How to decide the optimal scheme and the optimal time for construction

    1991-01-01

    Since the development in Norway began some 105 years ago the mean annual generation has reached approximately 110 TWh. This means that there is a large potential for uprating and refurbishing (U/R). A project undertaken by the Norwegian Water Resources and Energy Administration (NVE) has identified energy resources by means of U/R to about 10 TWh annual generation. One problem in harnessing the potential owned by small and medium sized electricity boards is the lack of simple tools to help us carry out the right decisions. The paper describes a simple model to find the best solution of scheme and the optimal time to start. The principle of present value is used. The main input is: production, price, annual costs of maintenance, the remaining lifetime and the social rate of return. The model calculates the present value of U/R/N for different points of time to start U/R/N. In addition the present value of the existing plant is calculated. Several alternatives can be considered. The best one will be the one which gives the highest present value according to the value of the existing plant. The internal rate of return is also calculated. To be aware of the sensitivity a star diagram is shown. The model gives the opportunity to include environmental charges and the value of effect (peak power). (Author)

  4. Crossing the Rubicon: Deciding to Become a Paramilitary in Northern Ireland

    Directory of Open Access Journals (Sweden)

    2008-06-01

    Full Text Available Northern Ireland has endured a history of violence since its inception in 1922. The last forty years have been characterised by sustained political conflict and a fledging peace process. We conducted a series of interviews with individuals who had used violence to pursue political goals during the conflict. This article focuses on the processes involved in their joining of paramilitary groups and engaging in violent actions. The participants’ accounts resonate with factors that other researchers have identified as being antecedent to paramilitary membership, such as having the support of the immediate community (e. g., Crawford 2003; Silke 2003. However, the rational decisions that are revealed in these accounts also show that participants engaged in rational decision making as opposed to being mindlessly provoked into membership in response to an environmental stimulus. These results highlight the degree to which individuals bear, and accept, personal responsibility for joining a paramilitary group (as opposed to membership simply being stimulated by uncontrollable dispositional or situational forces.

    To limit further comparisons between the two fasting indices Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI), and to examine their robustness in assessing insulin sensitivity. A total of 191 obese children and adolescents (age 13.9 ± 2.9 years, BMI SDS 6.1 ± 1.6), who had undergone a Frequently Sampled Intravenous Glucose Tolerance Test (FSIVGTT), were included. Receiver operating characteristic curve (ROC) analysis was used to compare indices in detecting insulin resistance and Bland-Altman plots to investigate agreement between three consecutive fasting samples when compared to using single samples. ROC analysis showed that the diagnostic accuracy was identical for QUICKI and HOMA-IR [area under the curve (AUC) boys 0.80, 95%CI 0.70-0.89; girls 0.80, 0.71-0.88], while insulin had a nonsignificantly lower AUC (boys 0.76, 0.66-0.87; girls 0.75, 0.66-0.84). Glucose did not perform better than chance as a diagnostic test (boys 0.47, 0.34-0.60; girls 0.57, 0.46-0.68). Indices varied with consecutive sampling, mainly attributable to fasting insulin variations (mean maximum difference in HOMA-IR -0.8; -0.9 to -0.7). Using both HOMA-IR and QUICKI in further studies is superfluous as these indices function equally well as predictors of the FSIVGTT sensitivity index. Focus should be on establishing a general standard for research and clinical purposes. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.

  10. Nerve Cells Decide to Orient inside an Injectable Hydrogel with Minimal Structural Guidance.

    Injectable biomaterials provide the advantage of a minimally invasive application but mostly lack the required structural complexity to regenerate aligned tissues. Here, we report a new class of tissue regenerative materials that can be injected and form an anisotropic matrix with controlled dimensions using rod-shaped, magnetoceptive microgel objects. Microgels are doped with small quantities of superparamagnetic iron oxide nanoparticles (0.0046 vol %), allowing alignment by external magnetic fields in the millitesla order. The microgels are dispersed in a biocompatible gel precursor and after injection and orientation are fixed inside the matrix hydrogel. Regardless of the low volume concentration of the microgels below 3%, at which the geometrical constrain for orientation is still minimum, the generated macroscopic unidirectional orientation is strongly sensed by the cells resulting in parallel nerve extension. This finding opens a new, minimal invasive route for therapy after spinal cord injury.

  11. Decision theory, motor planning, and visual memory: deciding where to reach when memory errors are costly.

    Science.gov (United States)

    Lerch, Rachel A; Sims, Chris R

    2016-06-01

    Limitations in visual working memory (VWM) have been extensively studied in psychophysical tasks, but not well understood in terms of how these memory limits translate to performance in more natural domains. For example, in reaching to grasp an object based on a spatial memory representation, overshooting the intended target may be more costly than undershooting, such as when reaching for a cup of hot coffee. The current body of literature lacks a detailed account of how the costs or consequences of memory error influence what we encode in visual memory and how we act on the basis of remembered information. Here, we study how externally imposed monetary costs influence behavior in a motor decision task that involves reach planning based on recalled information from VWM. We approach this from a decision theoretic perspective, viewing decisions of where to aim in relation to the utility of their outcomes given the uncertainty of memory representations. Our results indicate that subjects accounted for the uncertainty in their visual memory, showing a significant difference in their reach planning when monetary costs were imposed for memory errors. However, our findings indicate that subjects memory representations per se were not biased by the imposed costs, but rather subjects adopted a near-optimal post-mnemonic decision strategy in their motor planning.

  12. Deciding Which Way to Go: How Do Insects alter Movements to Negotiate Barriers?

    Directory of Open Access Journals (Sweden)

    Roy E. Ritzmann

    2012-07-01

    Full Text Available Animals must routinely deal with barriers as they move through their natural environment. These challenges require directed changes in leg movements and posture performed in the context of ever changing internal and external conditions. In particular, cockroaches use a combination of tactile and visual information to evaluate objects in their path in order to effectively guide their movements in complex terrain. When encountering a large block, the insect uses its antennae to evaluate the object’s height then rears upward accordingly before climbing. A shelf presents a choice between climbing and tunneling that depends on how the antennae strike the shelf; tapping from above yields climbing, while tapping from below causes tunneling. However, ambient light conditions detected by the ocelli can bias that decision. Similarly, in a T-maze turning is determined by antennal contact but influenced by visual cues. These multi-sensory behaviors led us to look at the central complex as a center for sensori-motor integration within the insect brain. Visual and antennal tactile cues are processed within the central complex and, in tethered preparations, several central complex units changed firing rates in tandem with or prior to altered step frequency or turning, while stimulation through the implanted electrodes evoked these same behavioral changes. To further test for a central complex role in these decisions, we examined behavioral effects of brain lesions. Electrolytic lesions in restricted regions of the central complex generated site specific behavioral deficits. Similar changes were also found in reversible effects of procaine injections in the brain. Finally, we are examining these kinds of decisions made in a large arena that more closely matches the conditions under which cockroaches forage. Overall, our studies suggest that CC circuits may indeed influence the descending commands associated with navigational decisions, thereby making them more context dependent.

    2012-01-01

    In criminal law, jurors are supposed to ignore defendant race when considering factual matters of culpability. However, when judging the merits of a criminal case, jurors' ability (or inability) to avoid bias may affect verdicts. Fact-based decision making expend cognitive resources, while heuristic-based decisions (e.g., using criminal stereotypes) conserve resources. Here, we investigated whether differences in cognitive resources and prejudice attitudes about Blacks influenced trial outcomes. We tested the impact of working memory capacity (WMC), cognitive load, prejudice, and target race (Black, White) on penalties ascribed to fictional criminal defendants in ambiguous-fact cases. Results showed that when "loaded," prejudiced-low-WMC persons supported guilty verdicts with higher confidence more often for Black than White defendants. Conversely, regardless of WMC or prejudice attitude, participants penalized White defendants more often when not loaded. We suggest that cognitive resources and prejudice attitude influence fact-based decisions. Links to juror judgments and potential trial outcomes are discussed.

  15. How to Decide? Multi-Objective Early-Warning Monitoring Networks for Water Suppliers

    Science.gov (United States)

    Bode, Felix; Loschko, Matthias; Nowak, Wolfgang

    2015-04-01

    Groundwater is a resource for drinking water and hence needs to be protected from contaminations. However, many well catchments include an inventory of known and unknown risk sources, which cannot be eliminated, especially in urban regions. As a matter of risk control, all these risk sources should be monitored. A one-to-one monitoring situation for each risk source would lead to a cost explosion and is even impossible for unknown risk sources. However, smart optimization concepts could help to find promising low-cost monitoring network designs. In this work we develop a concept to plan monitoring networks using multi-objective optimization. Our considered objectives are to maximize the probability of detecting all contaminations, to enhance the early warning time before detected contaminations reach the drinking water well, and to minimize the installation and operating costs of the monitoring network. Using multi-objectives optimization, we avoid the problem of having to weight these objectives to a single objective-function. These objectives are clearly competing, and it is impossible to know their mutual trade-offs beforehand - each catchment differs in many points and it is hardly possible to transfer knowledge between geological formations and risk inventories. To make our optimization results more specific to the type of risk inventory in different catchments we do risk prioritization of all known risk sources. Due to the lack of the required data, quantitative risk ranking is impossible. Instead, we use a qualitative risk ranking to prioritize the known risk sources for monitoring. Additionally, we allow for the existence of unknown risk sources that are totally uncertain in location and in their inherent risk. Therefore, they can neither be located nor ranked. Instead, we represent them by a virtual line of risk sources surrounding the production well. We classify risk sources into four different categories: severe, medium and tolerable for known risk sources and an extra category for the unknown ones. With that, early warning time and detection probability become individual objectives for each risk class. Thus, decision makers can identify monitoring networks valid for controlling the top risk sources, and evaluate the capabilities (or search for least-cost upgrades) to also cover moderate, tolerable and unknown risk sources. Monitoring networks, which are valid for the remaining risk also cover all other risk sources, but only with a relatively poor early-warning time. The data provided for the optimization algorithm are calculated in a preprocessing step by a flow and transport model. It simulates, which potential contaminant plumes from the risk sources would be detectable where and when by all possible candidate positions for monitoring wells. Uncertainties due to hydro(geo)logical phenomena are taken into account by Monte-Carlo simulations. These include uncertainty in ambient flow direction of the groundwater, uncertainty of the conductivity field, and different scenarios for the pumping rates of the production wells. To avoid numerical dispersion during the transport simulations, we use particle-tracking random walk methods when simulating transport.

    Given that screening for prostate cancer has the potential to reduce prostate cancer mortality at the expense of considerable overdiagnosis and overtreatment, the availability of core consumer information - correct, balanced and supportive of autonomous decision-making - is a must. We assessed the quality of consumer information available through the Internet per November 2009 and its possible contribution to informed decision-making by potential screenees. Consumer information on PSA-screening was sought through the Internet in November 2009. Materials had to be targeted at potential consumers, offered by not-for-profit organisations, released in 2005 or after, in English or Dutch. Per material 2 of the authors assessed independently from each other whether standardised pre-defined topics were addressed, whether the content was correct and which approach was taken towards the decision-making process about uptake. Twenty-three materials were included, of which 11 were released (shortly) after the results of 2 large randomized-controlled trials (RCTs) that evaluated the effectiveness of screening for prostate cancer had been published in March 2009. That a PSA-test result can be abnormal because of non-cancerous conditions (false positive) and that it may miss prostate cancer (false negative) was not addressed in 2/23 and 8/23 materials, respectively. The risk of overdiagnosis and overtreatment was not mentioned in 6 out of 23. PSA-screening was presented as a usual thing to do in some materials, whereas other materials emphasised the voluntary nature of PSA-screening ('it is your decision'). The content of 19/23 materials was considered sufficiently informative according to the pre-defined criteria, 12/23 materials were considered supportive of informed decision-making by men. Most materials of not-for-profit organizations supplied adequate information about PSA-screening, whilst the degree of persuasion towards uptake reflected variations in opinions on men's autonomy regarding their own health.

  17. Deciding to adopt revised and new psychological and neuropsychological tests: an inter-organizational position paper.

    2018-04-01

    Neuropsychological tests undergo periodic revision intended to improve psychometric properties, normative data, relevance of stimuli, and ease of administration. In addition, new tests are developed to evaluate psychological and neuropsychological constructs, often purporting to improve evaluation effectiveness. However, there is limited professional guidance to neuropsychologists concerning the decision to adopt a revised version of a test and/or replace an older test with a new test purporting to measure the same or overlapping constructs. This paper describes ethical and professional issues related to the selection and use of older versus newer psychological and neuropsychological tests, with the goal of promoting appropriate test selection and evidence-based decision making. Ethical and professional issues were reviewed and considered. The availability of a newer version of a test does not necessarily render obsolete prior versions of the test for purposes that are empirically supported, nor should continued empirically supported use of a prior version of a test be considered unethical practice. Until a revised or new test has published evidence of improved ability to help clinicians to make diagnostic determinations, facilitate treatment, and/or assess change over time, the choice to delay adoption of revised or new tests may be viewed as reasonable and appropriate. Recommendations are offered to facilitate decisions about the adoption of revised and new tests. Ultimately, it is the responsibility of individual neuropsychologists to determine which tests best meet their patients' needs, and to be able to support their decisions with empirical evidence and sound clinical judgment.

  18. Economic evaluation of heat extraction from nuclear power plants - a criterion for deciding their building order

    Navratil, J.

    1987-01-01

    Heat extraction from nuclear power plants is an important element in the current concept of supplying the population and industries with heat. Economic evaluation of the extraction is one of the factors of the total economic assessment of potential sites for nuclear power plant construction which can contribute to decision making on the priorities of construction. The methodological approach to the assessment of economic contribution of heat extraction from 2x1000 MW nuclear power plant is exemplified using three such sites on the Czechoslovak territory, viz., Opatovice (eastern Bohemia), Blahutovice (northern Moravia), and Kecerovce (eastern Slovakia). The so-called annual converted cost was used as a suitable quantity completely reflecting all significant economic effects of heat extraction. It is shown that the fuel component of the power plant costs is the decisive factor for the amount of the annual converted cost in respect to heat supply and thus also the economic priority of the construction sites of nuclear power plants.

    For patients with low-lying rectal cancer, the feasibility of anus-preserving surgery in combination with neoadjuvant chemoradiotherapy (NACRT) has been not well established from the perspective of patient-centered outcomes. We investigated 278 patients with low-lying rectal adenocarcinoma from 2005 to 2012. We compared their symptoms and QOL scores of patients who underwent anus-preserving surgery with (n = 88) and without (n = 143) NACRT according to the Wexner scale, EORTC QLQ C-30, CR29, and the modified fecal incontinence quality life scale (mFIQL). Furthermore, to assess the rationale for intersphincteric resection (ISR) with NACRT, we also compared QOL of patients who underwent ISR with NACRT (n = 31) and abdominoperineal resection (APR, n = 47). The adjusted mean differences of the Wexner score estimates of the patients who underwent ISR and very low anterior resection (VLAR) with or without NACRT were 5.29 (P = 0.004) and 2.67 (P = 0.009), respectively. No significant difference was observed in the QOL scores of two treatment groups. Furthermore, there were no significant differences in the QOL or function scores of patients who underwent ISR with NACRT and APR. The incontinence was significantly worse in patients who receive NACRT. However, there were no significant differences in their QOL or function scores. J. Surg.

    Full Text Available Aim. Callus is a risk factor, leading to severe diabetic foot ulcer; thus, prevention of callus formation is important. However, normal stress (pressure and shear stress associated with callus have not been clarified. Additionally, as new valuables, a shear stress-normal stress (pressure ratio (SPR was examined. The purpose was to clarify the external force associated with callus formation in patients with diabetic neuropathy. Methods. The external force of the 1st, 2nd, and 5th metatarsal head (MTH as callus predilection regions was measured. The SPR was calculated by dividing shear stress by normal stress (pressure, concretely, peak values (SPR-p and time integral values (SPR-i. The optimal cut-off point was determined. Results. Callus formation region of the 1st and 2nd MTH had high SPR-i rather than noncallus formation region. The cut-off value of the 1st MTH was 0.60 and the 2nd MTH was 0.50. For the 5th MTH, variables pertaining to the external forces could not be determined to be indicators of callus formation because of low accuracy. Conclusions. The callus formation cut-off values of the 1st and 2nd MTH were clarified. In the future, it will be necessary to confirm the effect of using appropriate footwear and gait training on lowering SPR-i.

  6. Tuning of electrostatic vs. depletion interaction in deciding the phase behavior of nanoparticle-polymer system

    International Nuclear Information System (INIS)

    Kumar, Sugam; Aswal, V. K.; Kohlbrecher, J.

    2015-01-01

    Nanoparticle-polymer system interestingly show a re-entrant phase behavior where charge stabilized silica nanoparticles (phase I) undergo particle clustering (phase II) and then back to individual particles (phase I) as a function of polymer concentration. Such phase behavior arises as a result of dominance of various interactions (i) nanoparticle-nanoparticle electrostatic repulsion (ii) polymer induced attractive depletion between nanoparticles and (iii) polymer-polymer repulsion, at different concentration regimes. Small-angle neutron scattering (SANS) has been used to study the evolution of interaction during this re-entrant phase behavior of nanoparticles by contrast-marching the polymer. The SANS data have been modeled using a two-Yukawa potential accounting for both attractive and repulsive parts of the interaction between nanoparticles. The degree of both of these parts has been separately tuned by varying the polymer concentration and ionic strength of the solution. Both of these parts are found to have long-range nature. At low polymer concentrations, the electrostatic repulsion dominates over the depletion attraction. The magnitude and the range of the depletion interaction increase with the polymer concentration leading to nanoparticle clustering. At higher polymer concentrations, the increased polymer-polymer repulsion reduces the strength of depletion leading to re-entrant phase behavior. The clusters formed under depletion attraction are found to have surface fractal morphology

    2018-05-01

    Recent protests on dozens of campuses have led to the cancellation of controversial talks, and violence has accompanied several of these protests. Psychological science provides an important lens through which to view, understand, and potentially reduce these conflicts. In this article, we frame opposing sides' arguments within a long-standing corpus of psychological research on selective perception, confirmation bias, myside bias, illusion of understanding, blind-spot bias, groupthink/in-group bias, motivated skepticism, and naive realism. These concepts inform dueling claims: (a) the protestors' violence was justified by a higher moral responsibility to prevent marginalized groups from being victimized by hate speech, versus (b) the students' right to hear speakers was infringed upon. Psychological science cannot, however, be the sole arbiter of these campus debates; legal and philosophical considerations are also relevant. Thus, we augment psychological science with insights from these literatures to shed light on complexities associated with positions supporting free speech and those protesting hate speech. We conclude with a set of principles, most supported by empirical research, to inform university policies and help ensure vigorous freedom of expression within the context of an inclusive, diverse community.

  9. Develop, Discuss, and Decide: How New Science Teachers Use Technologies to Advance Their Practice

    Science.gov (United States)

    Ellis, Joshua Alexander

    For decades, there has been a nationwide demand to increase the number of science teachers in K-12 education (National Commission on Excellence in Education, 1983; National Research Council [NRC], 2007). This demand is in large part due to increases in state science graduation requirements. Teacher preparation programs have been preparing new science teachers on pace with the resulting increase in demand (Ingersoll & Merrill, 2010), however, shortages have continued as up to 50% of these new teachers leave the profession within their first five years of teaching (Smith & Ingersoll, 2004), creating a "revolving door" phenomenon as districts scramble to address this early attrition with yet more beginning teachers. We need to address what Ingersoll (2012) describes as the "greening" of the teaching force: the fact that an increasingly large segment of the teaching force is comprised of beginning teachers who are at a high risk of leaving the profession. The three related studies that comprise this dissertation focus on the role of technological interventions for in-service and pre-service science teachers. The context for the first two studies is TIN, an online induction program for beginning secondary science teachers. These two studies consider the impact of technological supports on the reflective practice of participating teachers. The design interventions included VideoANT (an online video annotation tool) and Teachers as Leaders roles (a structured response protocol) for the Venture/Vexation online forum activity. The context for the third study is T3-S, a university licensure course for pre-service science teachers designed to explore technology integration in secondary science classrooms. This study investigated the impact of pre-service teacher participation in the creation of an Adventure Learning (AL) environment (Doering, 2006) on their understanding of technological, pedagogical, and content knowledge (TPACK) and its role in their future science instruction. The supporting interventions took the form of three separate groups of pre-service teachers, each tasked with a specific role in the creation of the AL environment. Findings from the first two studies indicate that specific, explicit supports for teacher discourse in TIN activities is needed in order to foster the reflective practice that course designers and instructor-facilitators desire. The third study reveals that pre-service teacher participation in the creation of an AL environment supported their understanding of the nature of TPACK and allowed them to define their content-based technology pedagogy for future science instruction.

  10. Nuclear waste management policies in the world: deciding today while leaving manoeuvre margins for tomorrow

    Massou, F.; Gras, A.

    2005-01-01

    The author first gives an overview of the definition of nuclear wastes, of their different types, and of their origins. He describes the waste production process by nuclear plants, and presents the case of high-level long-lived nuclear wastes. He outlines the need for a political processing of these wastes as they have been produced by public policies, and as decisions now concern and involve scientists, local interests and the civil society. Then, he describes the various technologies (storage, separation-transmutation, disposal), discusses their potential impacts, advantages and drawbacks, and how to take a political decision on them. He discusses the lessons learned from the German and Finnish examples and experiments in geological storage. He discusses the financing issue, notably from these examples

  18. HOW BOXERS DECIDE TO PUNCH A TARGET: EMERGENT BEHAVIOUR IN NONLINEAR DYNAMICAL MOVEMENT SYSTEMS

    Directory of Open Access Journals (Sweden)

    Robert Hristovski

    2006-07-01

    Full Text Available Previous research has shown how dynamical systems theory provides a relevant framework for investigating decision-making behavior in sport. The aim of this study was to adopt concepts and tools from nonlinear dynamics in examining effects of boxer-target distance and perceived punching efficiency on emergent decision-making during a typical practice task in boxing. Results revealed the existence of critical values of scaled distances between boxers and targets for first time appearance and disappearance of a diverse range of boxing actions including jabs, hooks and uppercuts. Reasons for the diversity of actions were twofold: i abrupt (qualitative changes in the number of the possible punches, i.e. motor solutions to the hitting task; and ii, fine modification of the probabilities of selecting specific striking patterns. Boxers were able to exploit the emerging perception of strikeability, leading to a changing diversity of selected actions and a cascade of abrupt changes in the perceptual-motor work space of the task. Perceived efficiency of a punching action by the participants also changed as a function of the scaled distance to a target and was correlated with the probability of occurrence of specific boxing actions. Accordingly, scaled distance-dependent perceived efficiency seems an important perceptual constraint in the training task of punching a heavy bag in boxers

  20. Deciding why and when to use CT in children: a radiologist's perspective

    Frush, Donald P.

    2014-01-01

    Defining what is appropriate or inappropriate with respect to CT scanning is challenging. There are a variety of influences on scan utilization in children, some more widely recognized and acknowledged than others. It is important to understand the contribution of these elements as we move toward improved utilization. This must be through partnerships and shared efforts and accountability. These efforts include improved resources such as consensus appropriateness criteria and guidelines including decision rules and support. But there also need to be trench-based strategies on the part of practicing radiologists to model cooperative behavior rather than blame-centered behavior. (orig.)

    Cyclitols are phytochemicals naturally occurring in plant material, which attracted an increasing interest due to multiple medicinal attributes, among which the most important are the antidiabetic, antioxidant, and anticancer properties. Due to their valuable properties, sugars are used in the food industry as sweeteners, preservatives, texture modifiers, fermentation substrates, and flavoring and coloring agents. In this study, we report for the first time the quantitative analysis of sugars and cyclitols isolated from Solidago virgaurea L., which was used for the selection of the optimal solvent and extraction technique that can provide the best possible yield. Moreover, the quantities of sugars and cyclitols extracted from two other species, Solidago canadensis and Solidago gigantea, were investigated using the best extraction method and the most appropriate solvent. Comparative analysis of natural plant extracts obtained using five different techniques-maceration, Soxhlet extraction, pressurized liquid extraction, ultrasound-assisted extraction, and supercritical fluid extraction-was performed in order to decide the most suitable, efficient, and economically convenient extraction method. Three different solvents were used. Analysis of samples has been performed by solid-phase extraction for purification and pre-concentration, followed by derivation and GC-MS analysis. Highest efficiency for the total amount of obtained compounds has been reached by PLE, when water was used as a solvent. d-pinitol amount was almost similar for every solvent and for all the extraction techniques involved. © 2018 WILEY-VCH Verlag GmbH & Co.

    In a follow-up study to our reports of N-cinnamoylated chloroquine and quinacrine analogues as promising dual-stage antimalarial leads with high in vitro potency against both blood-stage Plasmodium falciparum and liver-stage Plasmodium berghei, we decided to investigate the effect of replacing the cinnamoyl moiety with other acyl groups. Thus, a series of N-acylated analogues were synthesized, and their activities against blood- and liver-stage Plasmodium spp. were assessed along with their in vitro cytotoxicities. Although the new N-acylated analogues were found to be somewhat less active and more cytotoxic than their N-cinnamoylated counterparts, they equally displayed nanomolar activities in vitro against blood-stage drug-sensitive and drug-resistant P. falciparum, and significant in vitro liver-stage activity against P. berghei. Therefore, it is demonstrated that simple N-acylated surrogates of classical antimalarial drugs are promising dual-stage antimalarial leads. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Reliable detection of peptides in LC-MS data is a key algorithmic step in the analysis of quantitative proteomics experiments. While highly abundant peptides can be detected reliably by most modern software tools, there is much less agreement on medium and low-intensity peptides in a sample. The choice of software tools can have a big impact on the quantification of proteins, especially for proteins that appear in lower concentrations. However, in many experiments, it is precisely this region of less abundant but substantially regulated proteins that holds the biggest potential for discoveries. This is particularly true for discovery proteomics in the pharmacological sector with a specific interest in key regulatory proteins. In this viewpoint article, we discuss how the development of novel software algorithms allows us to study this region of the proteome with increased confidence. Reliable results are one of many aspects to be considered when deciding on a bioinformatics software platform. Deployment into existing IT infrastructures, compatibility with other software packages, scalability, automation, flexibility, and support need to be considered and are briefly addressed in this viewpoint article. © 2015 WILEY-VCH Verlag GmbH & Co.

  4. Effect of substrate mis-orientation on GaN thin films grown by MOCVD under different carrier gas condition

    2005-05-01

    We have studied the effect of a slight mis-orientation angle on surface and crystal quality of GaN thin films grown under different carrier gas conditions. Two types of carrier gas conditions were applied to the growth. One was pure H{sub 2} and the other was mixed N{sub 2}/H{sub 2}. As the result, we found dependence of surface and crystal quality of GaN thin films on the substrate mis-orientation angle, and they indicated almost the same tendency under both growth conditions. Therefore, it was confirmed that mis-orientation angle of sapphire substrate was one of the most critical factors for GaN thin films. Then, the effect of the additional N{sub 2} into the conventional H{sub 2} carrier gas was studied, and we found that the conversion of carrier gas from the conventional H{sub 2} to N{sub 2}/H{sub 2} mixture was effective against degradation of GaN crystallinity at any mis-orientation angle. Considering that the crystal quality of GaN thin films became insensitive to mis-orientation angle as the condition became more suitable for GaN growth, the optimal substrate mis-orientation angle was consequently decided to be approximately 0.15 from the morphological aspect.

    Web services play a key role in bioinformatics enabling the integration of database access and analysis of algorithms. However, Web service repositories do not usually publish information on the changes made to their registered Web services. Dynamism is directly related to the changes in the repositories (services registered or unregistered) and at service level (annotation changes). Thus, users, software clients or workflow based approaches lack enough relevant information to decide when they should review or re-execute a Web service or workflow to get updated or improved results. The dynamism of the repository could be a measure for workflow developers to re-check service availability and annotation changes in the services of interest to them. This paper presents a review on the most well-known Web service repositories in the life sciences including an analysis of their dynamism. Freshness is introduced in this paper, and has been used as the measure for the dynamism of these repositories. © 2017 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.

  18. Original research: Giving sexual assault survivors time to decide: an exploration of the use and effects of the nonreport option.

    Forensic nurses, sexual assault nurse examiners (SANEs), and victim advocates have long recognized the trauma of sexual assault crimes and the significance of survivors' decisions around reporting these crimes to law enforcement agencies. Until recently, survivors who didn't report the crime were not entitled to a free medical forensic examination. In a significant policy shift, the Violence Against Women and Department of Justice Reauthorization Act of 2005 provided an additional decision option with regard to the medical examination for survivors of sexual assault. This provision, referred to here as the nonreport option, was established to offer survivors a full range of reporting options and to ensure exemplary health care, with evidence collection as an important secondary goal. This study sought to examine the implementation of the nonreport option in Texas; explore its impact on SANEs, survivors, and the criminal justice system; and identify strengths and challenges of the nonreport process. A mixed-method approach was used that included qualitative interviews with 79 professionals who regularly respond to sexual assault crimes, a Web-based survey questionnaire of such professionals that yielded 131 completed surveys, and a review of existing data. The step-by-step process involved in a nonreport case was described, and findings in three descriptive areas emerged: confidentiality processes, storage and shipment of evidence, and the use of the nonreport option. Beneficial effects of the nonreport option were identified in five areas: the role of SANEs, the impact on survivors, collaborative relationships, collateral crimes, and anonymous reporting strategies. Seven areas of remaining dilemmas were also identified. Findings indicate that the nonreport option has had a considerable positive impact on SANEs, survivors of sexual assault, and the criminal justice system. But challenges remain if this option is to be fully utilized in the future; further research is warranted. The authors also present recommendations to improve health care delivery.

    Aim: To compare the diagnostic utility of pelvic ultrasound (US) and magnetic resonance imaging (MRI) on the clinical decision to proceed with uterine artery embolization (UAE). Materials and methods: Over 2 years, 180 consecutive women (mean age 43) sought consultation for UAE, 116 underwent pelvic US and MRI before possible UAE. US was performed prior to MRI. Imaging was analysed for leiomyoma quantity, size and location, uterine volume, and the presence of potential contraindications to UAE. Discrepancies between imaging methods and cases where discrepancies could have altered management, were recorded. Results: For the 116 patients who completed imaging, the average uterine volume was 701 cm 3 using MRI versus 658 cm 3 using US (p = 0.48). The average dominant leiomyoma volume was 292 cm 3 using MRI versus 253 cm 3 using US (p = 0.16). In 14 (12.1%) patients US did not correctly quantify or localize leiomyomas compared with MRI (p = 0.0005). Thirteen patients did not undergo UAE (patient preference n = 9, pre-procedural imaging findings n = 4). In the four cases where UAE was not performed due to imaging findings, relevant findings were all diagnosed by MRI compared with two by US (p = 0.5). The two cases not detected by ultrasound were adenomyosis and a pedunculate subserosal leiomyoma. Of the 103 patients who underwent UAE, 14 were treated (without complication) despite the presence of a relative contraindication; all 14 relative contraindications were identified by MRI compared with 13 by US (p = 1.0). Conclusion: MRI is more accurate than US for characterizing uterine leiomyomas. In a small but statistically insignificant number of cases, MRI identified findings that were missed by US, which changed management. For patients that are unsuitable to be assessed with MRI, ultrasound alone is sufficient for pre-UAE assessment.

    Three experiments explored how hypocrisy affects attributions of criminal guilt and the desire to punish hypocritical criminals. Study 1 established that via perceived hypocrisy, a hypocritical criminal was seen as more culpable and was punished more than a non-hypocritical criminal who committed an identical crime. Study 2 expanded on this, showing that negative moral emotions (anger and disgust) mediated the relationships between perceived hypocrisy, criminal guilt, and punishment. Study 3 replicated the emotion finding from Study 2 using new scenarios where group agents were clearly aware of the hypocrisy of their actions, yet acted anyway. Again, perceived hypocrisy worked through moral emotions to affect criminal guilt and punishment. The current studies provide empirical support for theories relating hypocrisy and moral transgressions to moral emotions, also informing the literature on the role of moral emotions in moral reasoning and legal decision making.

    This phenomenological study integrated crisis theory, social identity theory, and uncertainty management theory to conceptualize the decision-making process around institutionalization among nursing home residents and their children in Shanghai. I conducted face-to-face, semistructured interviews with 12 dyads of matched elders and their children (N = 24). The findings suggest that caregiving crises triggered intergenerational communication about caregiving alternatives and new arrangements, although each generation had different stances and motivations. Children finalized the decision by helping their parents to manage the uncertainties pertaining to institutionalization. This study sheds light on caregiving decision-making dynamics for the increasing aging population across cultures.

    Full Text Available Cellular stress‐induced temporal alterations—i.e., dynamics—are typically exemplified  by the dynamics of p53 that serve as a master to determine cell fate. p53 dynamics were initially  identified as the variations of p53 protein levels. However, a growing number of studies have  shown that p53 dynamics are also manifested in variations in the activity, spatial location, and  posttranslational modifications of p53 proteins, as well as the interplay among all p53 dynamical  features. These are essential in determining a specific outcome of cell fate. In this review, we  discuss the importance of the multifaceted features of p53 dynamics and their roles in the cell fate  decision process, as well as their potential applications in p53‐based cancer therapy. The review  provides new insights into p53 signaling pathways and their potentials in the development of new  strategies in p53‐based cancer therapy.

    Distributed cognition occurs when cognitive and affective schemas are shared between two or more people during interpersonal discussion. Although extant research focuses on distributed cognition in decision making between health care providers and patients, studies show that caregivers are also highly influential in the treatment decisions of patients. However, there are little empirical data describing how and when families exert influence. The current article addresses this gap by examining decisional support in the context of cancer randomized clinical trial (RCT) decision making. Data are drawn from in-depth interviews with rural, Appalachian cancer patients ( N = 46). Analysis of transcript data yielded empirical support for four distinct models of health decision making. The implications of these findings for developing interventions to improve the quality of treatment decision making and overall well-being are discussed.

  6. Did Raw Material Shortages Decide World War Two? New Data for the Example of Nazi Rubber Supplies

    Directory of Open Access Journals (Sweden)

    Paul Ferdinand Schmelzing

    2017-06-01

    Full Text Available Despite a well-established literature on the economics of World War Two, to this day reliable statistics on overall raw material supplies for Nazi Germany are lacking. The operations of shell companies, the special de jure status of occupied areas, and the Wehrmacht practice to “live off the land” have led to a significant underestimation of de facto resource endowments of the Third Reich. For the example of rubber—one of the prime “scarce war commodities”—this article demonstrates the extent and sources of deficiencies, and offers new data. On this basis, and in contrast to recent arguments that view raw materials as a “basic constraint” of the German economy, it is shown that surprisingly comfortable supplies existed between December 1941 and May 1944, during which Nazi-controlled Europe seemed ready to allow a realization of Hitler’s ‘Lebensraum’ designs. The failure to realize those designs originated in military setbacks—which subsequently impacted economic performance as a secondary effect.

  7. Different forms, reasons and motivations for return migration of persons who voluntarily decide to return to their countries of origin.

    1986-03-01

    Although the 1973 oil crisis did not have the drastic effects on immigration which were originally feared, it did end a period of quasi-liberal immigration policy, establish intense and effective international cooperation on immigration, and arouse great interest in immigration studies and research. This paper analyzes the situations arising as a result of the petroleum shortage and focuses on the conditions relating to the return of emigrants to Southern European countries. This new research draws attention to the following fundamental aspects of the immigration problem: 1) the emigrant's return to his homeland cannot be considered a factor in development; it is a positive element in development only if the right socioeconomic conditions exist in the country of origin. 2) Concern for children's education is one of the most common reasons for return. 3) A large percentage of emigrants are satisfied with their work abroad. 4) An emigrant's return potential is wasted due to the slight use that is made of the resources he offers. 5) Returning workers most often want to set up an independent enterprise. 6) Savings are generally used to buy a house or farm. 7) Vocational level does not increase significantly between emigration and returning, though this increase becomes greater the longer the emigrant stays abroad. 8) The number of returning emigrants is too slight to bring about any change in the country of origin. 9) Incentives and subsidies to encourage return have not had a considerable impact on the decision to return. Callea recommends that officials of the country of origin posted abroad be assigned to counsel returning emigrants on finding employment, attending vocational development courses, obtaining housing, accruing interests and savings, and on the problems and perspectives of sociocultural reintegration.

  8. Perspectives of young Chinese Singaporean women on seeking and processing information to decide about vaccinating against human papillomavirus.

    Human papillomavirus (HPV) vaccination uptake in Singapore is low among young women. Low uptake has been found to be linked to low awareness. Thus, this study aimed to understand active and passive vaccine information-seeking behavior. Furthermore, guided by the Elaboration Likelihood Model (ELM), this study examined young women's (aged 21-26 years) processing of information they acquired in their decision to get vaccinated. ELM postulates that information processing could be through the central (i.e., logic-based) or peripheral (i.e., heuristic-based) route. Twenty-six in-depth interviews were conducted from January to March 2016. Data were analyzed using thematic analysis. Two meta-themes-information acquisition and vaccination decision-revealed the heuristic-based information processing was employed. These young women acquired information passively within their social network and actively in healthcare settings. However, they used heuristic cues, such as closeness and trust, to process the information. Similarly, vaccination decisions revealed that women relied on heuristic cues, such as sense of belonging and validation among peers and source credibility and likability in medical settings, in their decision to get vaccinated. The findings of this study highlight that intervention efforts should focus on strengthening social support among personal networks to increase the uptake of the vaccine.

  9. Do Younger Researchers Assess Trustworthiness Differently when Deciding what to Read and Cite and where to Publish?

    Full Text Available An international survey of over 3600 academic researchers examined how trustworthiness is determined when making decisions on scholarly reading, citing, and publishing in the digital age and whether social media and open access publications are having an impact on judgements. In general, the study found that traditional scholarly methods and criteria remain important across the board. However, there are significant differences between younger (age 30 & under and older researchers (over 30. Thus younger researchers: a expend less effort to obtain information and more likely to compromise on quality in their selections; b view open access publishing much more positively as it offers them more choices and helps to establish their reputation more quickly; c compensate for their lack of experience by relying more heavily on trust markers and proxies, such as impact factors; d use all the outlets available in order to improve the chances of getting their work published and, in this respect, make the most use of the social media with which they are more familiar.

  10. Impaired driving from medical conditions: a 70-year-old man trying to decide if he should continue driving.

    Rizzo, Matthew

    2011-03-09

    Some medical disorders can impair performance, increasing the risk of driving safety errors that can lead to vehicle crashes. The causal pathway often involves a concatenation of factors or events, some of which can be prevented or controlled. Effective interventions can operate before, during, or after a crash occurs at the levels of driver capacity, vehicle and road design, and public policy. A variety of systemic, neurological, psychiatric, and developmental disorders put drivers at potential increased risk of a car crash in the short or long term. Medical diagnosis and age alone are usually insufficient criteria for determining fitness to drive. Strategies are needed for determining what types and levels of reduced function provide a threshold for disqualification in drivers with medical disorders. Evidence of decreased mileage, self-restriction to driving in certain situations, collisions, moving violations, aggressive driving, sleepiness, alcohol abuse, metabolic disorders, and multiple medications may trigger considerations of driver safety. A general framework for evaluating driver fitness relies on a functional evaluation of multiple domains (cognitive, motor, perceptual, and psychiatric) that are important for safe driving and can be applied across many disorders, including conditions that have rarely been studied with respect to driving, and in patients with multiple conditions and medications. Neurocognitive tests, driving simulation, and road tests provide complementary sources of evidence to evaluate driver safety. No single test is sufficient to determine who should drive and who should not.

  11. How ordinary judges and juries decide the seemingly complex technological questions of patentability over the prior art.

    Science.gov (United States)

    Kieff, F Scott

    2003-01-01

    Determinations of patentability over the prior art are often thought to raise questions that are so technologically complex that they require special training and judgment to answer, especially in fast-moving fields like modern biotechnology. This essay explores the somewhat counterintuitive argument that under the U.S. system they do not and should not. According to this view, determinations of patentability over the prior art are based entirely on factual inquiries that are best made by lay judges and juries, just like the factual determinations these people regularly make in any ordinary nonpatent trial. This is good because judges and juries are adept at these determinations, and because appellate courts are adept at reviewing them. It leads to a system that is cheaper overall in allowing private litigants to better predict outcomes that also better approximate the correct answer than would be possible under other regimes premised upon the expert technological knowledge and judgment of a decisionmaker.

    2015-01-01

    To explore the decision-making process of BSN faculty when determining which best practices to use for classroom testing. A descriptive, correlational study was conducted with a national sample (N = 127) of full-time BSN faculty. Participants completed a web-based survey incorporating instruments that measured beliefs about evaluation, decision-making, and best practices for item analysis and constructing and revising classroom tests. Study participants represented 31 states and were primarily middle-aged white women. In multiple linear regression analyses, faculty beliefs, contextual factors for decision-making, and decision-making processes accounted for statistically significant amounts of the variance in item analysis and test construction and revision. Strong faculty beliefs that rules were important when evaluating students was a significant predictor of increased use of best practices. Results support that understanding faculty beliefs around classroom testing is important in promoting the use of best practices.

    Many features of aging result from the incapacity of cells to adapt to stress conditions. When damage accumulates irreversibly, mitotic cells from renewable tissues rely on either of two mechanisms to avoid replication. They can permanently arrest the cell cycle (cellular senescence) or trigger cell death programs. Apoptosis (self-killing) is the best-described form of programmed cell death, but autophagy (self-eating), which is a lysosomal degradation pathway essential for homeostasis, reportedly contributes to cell death as well. Unlike mitotic cells, postmitotic cells like neurons or cardiomyocytes cannot become senescent since they are already terminally differentiated. The fate of these cells entirely depends on their ability to cope with stress. Autophagy then operates as a major homeostatic mechanism to eliminate damaged organelles, long-lived or aberrant proteins and superfluous portions of the cytoplasm. In this mini-review, we briefly summarize the molecular networks that allow damaged cells either to adapt to stress or to engage in programmed-cell-death pathways. (c) 2008 S. Karger AG, Basel.

    Full Text Available This study used a cross sectional sample created by self-selection from a researchers' email invitation to accountants in Canada to determine which modalities accountants preferred when selecting Continuing Professional Development (CPD, and the selection factors they used in making those choices. The survey contacted 32,000 accountants in Canada and a total of 428 accountants from across Canada completed the online survey. Live seminars and live webinars were the highest ranked and accountants preferred synchronous over asynchronous courses. The factors most important to accountants are content, cost and CPD hour requirements. The ranking of selection factors for synchronous courses in general did not differ from those for asynchronous courses with the exception of self-paced courses where the selection factors of “pace” and “time away from work” were ranked higher than for other courses. The results of the study indicate a continuing need for providers to ensure that courses are relevant and accessible to accountants. Further research is suggested into the differences noted between genders as well as other categorical differences. Work-life balance was a recurring theme that should also be explored further. Pedagogical use in the design of modalities is a further avenue for future research.

  19. A decision theory perspective on why women do or do not decide to have cancer screening: systematic review.

    Science.gov (United States)

    Ackerson, Kelly; Preston, Stephanie D

    2009-06-01

    This paper is a report of a review in which decision theory from economics and psychology was applied to understand why some women with access to care do not seek cancer screening. Mammography and cervical smear testing are effective modes of cancer screening, yet many women choose not to be screened. Nurses need to understand the reasons behind women's choices to improve adherence. Research papers published between January 1994 and November 2008 were identified using the Cumulative Index to Nursing and Allied Health Literature, MEDLINE and PsycINFO data bases. The search was performed using the following terms: cervical cancer screening, breast cancer screening, decision, choice, adherence and framing. Forty-seven papers were identified and reviewed for relevance to the search criteria. Nineteen papers met the search criteria. For each paper, reasons for obtaining or not obtaining cancer screening were recorded, and organized into four relevant decision theory principles: emotions, Prospect Theory, optimism bias and framing. All women have fears and uncertainty, but the sources of their fears differ, producing two main decision scenarios. Non-adherence results when women fear medical examinations, providers, tests and procedures, do not have/seek knowledge about risk and frame their current health as the status quo. Adherence is achieved when women fear cancer, but trust care providers, seek knowledge, understand risk and frame routine care as the status quo. Nurses need to address proactively women's perceptions and knowledge about screening by openly and uniformly discussing the importance and benefits.

  20. Internal cycling, not external loading, decides the nutrient limitation in eutrophic lake: A dynamic model with temporal Bayesian hierarchical inference.

    2017-06-01

    Lake eutrophication is associated with excessive anthropogenic nutrients (mainly nitrogen (N) and phosphorus (P)) and unobserved internal nutrient cycling. Despite the advances in understanding the role of external loadings, the contribution of internal nutrient cycling is still an open question. A dynamic mass-balance model was developed to simulate and measure the contributions of internal cycling and external loading. It was based on the temporal Bayesian Hierarchical Framework (BHM), where we explored the seasonal patterns in the dynamics of nutrient cycling processes and the limitation of N and P on phytoplankton growth in hyper-eutrophic Lake Dianchi, China. The dynamic patterns of the five state variables (Chla, TP, ammonia, nitrate and organic N) were simulated based on the model. Five parameters (algae growth rate, sediment exchange rate of N and P, nitrification rate and denitrification rate) were estimated based on BHM. The model provided a good fit to observations. Our model results highlighted the role of internal cycling of N and P in Lake Dianchi. The internal cycling processes contributed more than external loading to the N and P changes in the water column. Further insights into the nutrient limitation analysis indicated that the sediment exchange of P determined the P limitation. Allowing for the contribution of denitrification to N removal, N was the more limiting nutrient in most of the time, however, P was the more important nutrient for eutrophication management. For Lake Dianchi, it would not be possible to recover solely by reducing the external watershed nutrient load; the mechanisms of internal cycling should also be considered as an approach to inhibit the release of sediments and to enhance denitrification.

    The neural mechanisms by which intentions are transformed into actions remain poorly understood. We investigated the network mechanisms underlying spontaneous voluntary decisions about where to focus visual-spatial attention (willed attention). Graph-theoretic analysis of two independent datasets revealed that regions activated during willed attention form a set of functionally-distinct networks corresponding to the frontoparietal network, the cingulo-opercular network, and the dorsal attention network. Contrasting willed attention with instructed attention (where attention is directed by external cues), we observed that the dorsal anterior cingulate cortex was allied with the dorsal attention network in instructed attention, but shifted connectivity during willed attention to interact with the cingulo-opercular network, which then mediated communications between the frontoparietal network and the dorsal attention network. Behaviorally, greater connectivity in network hubs, including the dorsolateral prefrontal cortex, the dorsal anterior cingulate cortex, and the inferior parietal lobule, was associated with faster reaction times. These results, shown to be consistent across the two independent datasets, uncover the dynamic organization of functionally-distinct networks engaged to support intentional acts.

    In 1974, the European Economic Community established mutual recognition of medical qualifications obtained in any of its member states. Subsequently, a series of directives has elaborated on the initial provisions, with the most recent enacted in 2013. However, greater movement of physicians across borders and some high-profile scandals have raised questions about how to prevent a physician sanctioned in one country from simply moving to another, without undermining the principle of free movement. A survey of key informants in 11 European Union (EU) member states was supplemented by a review of peer-reviewed and grey literature, with the results validated by independent reviewers. It examined processes, adjudicative and disciplinary measures that are in place to evaluate physicians about whom concerns arise, and related sanctions, along with other aspects of professional standards and regulation. Overall, responses varied greatly between participating countries, with respect to the institutions responsible for the regulation of medical professions, the investigation processes in place, and the terminology used in each member state. While the types of sanction (removal from the register of medical professionals and/or licence revocation, suspension, dismissal, reprimand, warnings, fines, as well as additional education and training) applied are similar, both the roles of the individuals involved and the level of public disclosure of information vary considerably. However, some key features, such as the involvement of professional peers in disciplinary panels and the involvement of courts in criminal cases, are similar in most member states studied. Given the variation in the regulatory context, individuals and processes involved that is illustrated by our findings, a common understanding of definitions of what constitutes competence to practise, its impairment and its potential impact on patient safety becomes particularly important. Public disclosure of disciplinary outcomes is already applied by some member states, but additional measures should be considered to protect medical professionals from undue consequences. © Royal College of Physicians 2015.

    promoting vaginal births after caesarean section (VBAC) for eligible women and increasing rates of successful VBACs are the best strategies to reduce the number of repeat caesarean sections (CS). Knowledge of factors that are associated with women's decision-making around mode of birth after CS is important when developing strategies to promote VBAC. This study assessed which factors are associated with women's preferences for VBAC versus elective repeat caesarean section (ERCS) in a new pregnancy after one previous caesarean in Switzerland. cross-sectional web-survey. Western Switzerland. French-speaking women living in Western Switzerland, with one previous CS who gave birth subsequently to a child after a complication-free pregnancy were eligible to participate in the survey. Of 393 women who started the survey in November/December 2014, 349 were included: 227 who planned a VBAC and 122 who planned an ERCS at term. univariable and multivariable analyses were conducted to describe and compare women who had planned a VBAC with women who had planned an ERCS in a pregnancy following a CS. Logistic regression modelling was used to investigate predictors that were associated with a preference for a VBAC at term. Analyses were performed with SPSS 22 and Stata 13. of the women planning a VBAC, 62.6% VBAC gave birth vaginally. Predictors which were significantly associated with increased odds of women choosing a VBAC: duration since previous birth in years (OR=1.11 95% CI [1.03-1.20], p=0.010), having had midwifery care during pregnancy (OR=2.09, 95% CI [1.08-4.05], p=0.029), being advised by their healthcare provider to attempt a VBAC (OR=4.20, 95% CI [1.75-10.09], p=0.001), preference for VBAC during the third trimester of their pregnancy (OR=3.98, 95% CI [1.77-8.93], p=0.001), and wishing to let the child choose the moment of birth (OR=1.46, 95% CI[1.22-1.74], p<0.001). The importance of safety for the mother decreased the odds of women preferring a VBAC (OR=0.74, 95% CI [0.60-0.90], p=0.003) while a motivation for more immediate bonding with the baby after birth increased the odds of preferring a VBAC at term (OR=1.25, 95% CI [1.06-1.46], p=0.007). caregivers' recommendations about mode of birth after CS, women's preferences during the third trimester and midwifery care during pregnancy were found to be the most important predictors for preferring a VBAC at term. These results indicate that midwifery antenatal care might be a key factor for fostering women's preference for a VBAC. women with a history of CS who feel ambivalent about the mode of birth are likely to benefit from access to midwifery support.

    Some medical disorders can impair performance, increasing the risk of driving safety errors that can lead to vehicle crashes. The causal pathway often involves a concatenation of factors or events, some of which can be prevented or controlled. Effective interventions can operate before, during, or after a crash occurs at the levels of driver capacity, vehicle and road design, and public policy.

    MacLean, Alice; Sweeting, Helen; Walker, Laura; Patterson, Chris; Räisänen, Ulla; Hunt, Kate

    2015-05-29

    Recent qualitative research found young men reporting that an expectation that eating disorders (EDs) mainly affect young women led them, and others, to only recognise their symptoms when their ED had become entrenched. This raises questions about how these stereotypes persist. We therefore explored how EDs in males were represented in articles published in UK newspapers over a 10-year period (7.12.2002-7.12.2012), specifically attending to whether newsprint media represent EDs in males as 'gender appropriate', 'gender anomalous' or 'gender neutral'. A qualitative thematic analysis of UK newspaper articles. We searched two databases, Newsbank and LexisNexis, for newspaper articles including ED and male terms in the lead/first paragraph. Following de-duplication, 420 articles were scrutinised; 138 met inclusion criteria for detailed textual analysis and were imported into NVivo10. The number of articles peaked in 2008 when a UK politician announced that he had experienced bulimia nervosa. Analysis of how the articles portrayed male ED-related characterisations and experiences revealed that they conveyed ambiguous messages about EDs in males. Despite apparently aiming to dispel stereotypes that only young women experience EDs and to address stigma surrounding EDs in males, many aspects of the articles, including repetition of phrases such as 'a young woman's illness', serve to reinforce messages that EDs are inherently 'female' and so 'anomalous' for men. Newspaper articles represent men with EDs as atypical of men, as a result of having an ED (and any feminising or demasculinising characteristics associated with this), and as atypical of people with EDs, who are still usually portrayed as teenage girls. Such media representations frame a cultural paradigm in which there is an expectation that men may feel shame about or strive to conceal EDs, potentially contributing to men with EDs delaying help-seeking, gaining late access to treatments and reducing chances of successful outcomes.

    Fraher, Erin P; Knapton, Andy; Holmes, George M

    2017-02-01

    To outline a methodology for allocating graduate medical education (GME) training positions based on data from a workforce projection model. Demand for visits is derived from the Medical Expenditure Panel Survey and Census data. Physician supply, retirements, and geographic mobility are estimated using concatenated AMA Masterfiles and ABMS certification data. The number and specialization behaviors of residents are derived from the AAMC's GMETrack survey. We show how the methodology could be used to allocate 3,000 new GME slots over 5 years-15,000 total positions-by state and specialty to address workforce shortages in 2026. We use the model to identify shortages for 19 types of health care services provided by 35 specialties in 50 states. The new GME slots are allocated to nearly all specialties, but nine states and the District of Columbia do not receive any new positions. This analysis illustrates an objective, evidence-based methodology for allocating GME positions that could be used as the starting point for discussions about GME expansion or redistribution. © Health Research and Educational Trust.

    2018-02-01

    There is an increasing request by patients or their representatives not to have some data registered in their clinical history or if such data exists to be deleted. Without doubt, this is so because such clinical data is accessed by various professionals who in most cases are not directly involved in caring for such patients. On the other hand, such data is copied and iteratively and unnecessary reproduced in various discharge reports and others forms. The problem arises when such controversial data refer to particularly sensitive clinical aspects such as assisted reproduction techniques, which invades personal and family privacy. Therefore, the question is who determines what data should be recorded in the medical records and according to what criteria should be taken that decision? Copyright © 2017 Elsevier España, S.L.U.

    In an on-line coloring, the vertices of a graph are revealed one by one. An algorithm assigns a color to each vertex after it is revealed. When a vertex is revealed, it is also revealed which of the previous vertices it is adjacent to. The on-line chromatic number of a graph, G, is the smallest...... number of colors an algorithm will need when on-line-coloring G. The algorithm may know G, but not the order in which the vertices are revealed.

    A shared-control scheme for a powered wheelchair is presented. The wheelchair can be operated by a wheelchair driver using a joystick, or directed by a sensor system, or control can be combined between them. The wheelchair system can modify direction depending on the local environment. Sharing the control allows a disabled wheelchair driver to drive safely and efficiently. The controller automatically establishes the control gains for the sensor system and the human driver by calculating a self-reliance factor for the wheelchair driver. The sensor system can influence the motion of the wheelchair to compensate for some deficiency in a disabled driver. Practical tests validate the proposed techniques and designs.

    2003-10-01

    Although mathematical relationships can be proven by deductive logic, biological relationships can only be inferred from empirical observations. This is a distinct disadvantage for those of us who strive to identify the genes involved in complex diseases and quantitative traits. If causation cannot be proven, however, what does constitute sufficient evidence for causation? The philosopher Karl Popper said, "Our belief in a hypothesis can have no stronger basis than our repeated unsuccessful critical attempts to refute it." We believe that to establish causation, as scientists, we must make a serious attempt to refute our own hypotheses and to eliminate all known sources of bias before association becomes causation. In addition, we suggest that investigators must provide sufficient data and evidence of their unsuccessful efforts to find any confounding biases. In this editorial, we discuss what "causation" means in the context of complex diseases and quantitative traits, and we suggest guidelines for steps that may be taken to address possible confounders of association before polymorphisms may be called "causative."

    2007-07-01

    Full Text Available Abstract Background The unequal use of mental health care is a great issue, even in countries with universal health coverage. Better knowledge of the factors that have an impact on the pathway to mental health care may be a great help for designing education campaigns and for best organizing health care delivery. The objective of this study is to explore the determinants of help-seeking intentions for mental health problems and which factors influence treatment opinions and the reliance on and compliance with health professionals' advice. Methods 441 adults aged 18 to 70 were randomly selected from the general population of two suburban districts near Paris and agreed to participate in the study (response rate = 60.4%. The 412 respondents with no mental health problems based on the CIDI-SF and the CAGE, who had not consulted for a mental health problem in the previous year, were asked in detail about their intentions to seek help in case of a psychological disorder and about their opinion of mental health treatments. The links between the respondents' characteristics and intentions and opinions were explored. Results More than half of the sample (57.8% would see their general practitioner (GP first and 46.6% would continue with their GP for follow-up. Mental health professionals were mentioned far less than GPs. People who would choose their GP first were older and less educated, whereas those who would favor mental health specialists had lower social support. For psychotherapy, respondents were split equally between seeing a GP, a psychiatrist or a psychologist. People were reluctant to take psychotropic drugs, but looked favorably on psychotherapy. Conclusion GPs are often the point of entry into the mental health care system and need to be supported. Public information campaigns about mental health care options and treatments are needed to educate the public, eliminate the stigma of mental illness and eliminate prejudices.

    Participants were 57 U.S. college students and 56 Polish university students and copper mine workers who judged the intimacy of 9 hypothetical relationships and also rated the intensity of their relationships with a best friend, a friend, and an acquaintance on the Friendship Intensity Measurement Scale (FIMS; T. S. Arunkumar & B. Dharmangadan, 2001). The present results confirmed that people perceive (a) relationships with best friends as more intense and intimate than other friendships and (b) other friendships as more intense and intimate than acquaintanceships. The results also indicated that Americans perceive all of their relationships, ranging from mere acquaintanceships to intimate friendships, as more intense and intimate than do Poles. It was somewhat surprising that there were no sex differences in either country in the perception of relationships. The authors discussed the research in the context of the difficulty of defining what friendship is and how an individual's cultural background might interact with person variables such as age and sex.

    The efficiency of privatised companies has been modified by the market liberalisation and the regulation of governments. However, to analyse the performance of these companies is necessary to consider their internal organisational changes. Therefore, in this study we analyse factors that leads to the restructuring of privatised companies. Specifically, we describe the influence of capital markets, corporate governance system and changes of boards on the efficiency of privatised companies. In order to contribute to privatisation process in Spain o test whether the performance improves with the influence of capital markets, we carry out an empirical study of financial performance for quoted and non-quoted companies privatised in Spain.

  9. Reactive oxygen species (ROS – a family of fate deciding molecules pivotal in constructive inflammation and wound healing

    Directory of Open Access Journals (Sweden)

    N Bryan

    2012-09-01

    Full Text Available Wound healing requires a fine balance between the positive and deleterious effects of reactive oxygen species (ROS; a group of extremely potent molecules, rate limiting in successful tissue regeneration. A balanced ROS response will debride and disinfect a tissue and stimulate healthy tissue turnover; suppressed ROS will result in infection and an elevation in ROS will destroy otherwise healthy stromal tissue. Understanding and anticipating the ROS niche within a tissue will greatly enhance the potential to exogenously augment and manipulate healing.Tissue engineering solutions to augment successful healing and remodelling of wounded or diseased tissue rely on a controlled balance between the constructive and destructive capacity of the leukocyte secretome, including ROS.This review comprehensively considers leukocyte derived ROS in tissue repair with particular interest in surgical intervention with inclusion of a biomaterial. The article considers ROS fundamental chemistry, formation, stimulation and clearance before applying this to discuss the implications of ROS in healing tissue with and without a biomaterial. We also systematically discuss ROS in leukocyte signalling and compare and contrast experimental means of measuring ROS.

  10. Deciding between carbon trading and carbon capture and sequestration: an optimisation-based case study for methanol synthesis from syngas.

    2014-01-01

    The economic and technical feasibility of carbon capture and sequestration (CCS) systems are gaining importance as CO2 emission reduction is becoming a more pressing issue for parties from production sectors. Public and private entities have to comply with national schemes imposing tighter limits on their emission allowances. Often these parties face two options as whether to invest in CCS or buy carbon credits for the excess emissions above their limits. CCS is an expensive system to invest in and to operate. Therefore, its feasibility depends on the carbon credit prices prevailing in the markets now and in the future. In this paper we consider the problem of installing a CCS unit in order to ensure that the amount of CO2 emissions is within its allowable limits. We formulate this problem as a non-linear optimisation problem where the objective is to maximise the net returns from pursuing an optimal mix of the two options described above. General Algebraic Modelling Systems (GAMS) software was used to solve the model. The results were found to be sensitive to carbon credit prices and the discount rate, which determines the choices with respect to the future and the present. The model was applied to a methanol synthesis plant as an example. However, the formulation can easily be extended to any production process if the CO2 emissions level per unit of physical production is known. The results showed that for CCS to be feasible, carbon credit prices must be above 15 Euros per ton. This value, naturally, depends on the plant-specific data, and the costs we have employed for CCS. The actual prices (≈5 Euros/ton CO2) at present are far from encouraging the investors into CCS technology. Copyright © 2013 Elsevier Ltd. All rights reserved.

    All applicants to round 1 of national recruitment into the general practice specialty recruitment process were surveyed as to the reasons for, and the timing of their career choices. Most applicants reported decision making after completing undergraduate training citing variety, continuity of care and work-life balance as their main drivers for a career in general practice. Applicants were statistically more likely to have undertaken a Foundation placement in general practice than their peers on a Foundation programme. Reasons for choice of deanery were largely related to location and social ties, rather than to the educational 'reputation' of its programmes.

    Nuclear power plants generate many kinds of hazardous nuclear waste which are needed to be disposed in an eco-friendly manner. Many different waste incarceration techniques have been adapted for managing the nuclear waste of different category of radioactivity. Immobilisation of low and intermediate level radioactive wastes in cement matrix is one of the widely used and cost-effective techniques in waste management. However, loading of nuclear waste in cement matrix can alter the mesoscopic structure of the hydrated cement and hence, it is very important to set the maximum limit of waste loading in cement for providing proper physical isolation to the nuclear waste

    Several recent publications have illustrated that electrostatic attraction is not solely responsible for strong hydrogen bonds. Even electropositive and less electronegative atoms such as Te and Se are capable of forming strong H-bonds. Herein, we provide evidence for intramolecular homopolar dihydrogen bonds [HOMO-DHBs; X-N(C)-H δ+ ⋅⋅⋅ δ+ H-N(C)-Y] in porphyrins and related compounds for the first time; these bonds are revealed by careful Cambridge Structural Database (CSD) exploration, quantum theory of atoms in molecules, compliance constant calculations, and natural bond orbital and noncovalent interaction (NCI) analysis. A search of the CSD showed that the inner-core hydrogen atom distances were less than 2.5 Å (sum of the van der Waals radii of two hydrogen atoms is 2.4 Å) in porphyrinoids, i.e. about 75 % of the cases. This suggested an attractive interaction between hydrogen atoms carrying a positive charge, which was further supported by quantum-chemical calculations. The HOMO-DHB energy in some cases was found to be as much as around 20 kJ mol -1 , which is comparable to that of any conventional H-bond energy such as for the NH 3 dimer. The interplay between hyperconjugative attraction and steric constraint favorably decided the strength of the HOMO-DHBs. We expect that HOMO-DHBs could be revealed in many more systems, such as corroles, phlorins, crown ethers, and constrained systems having hydrogen atoms in close contact, and could be an important noncovalent interaction to consider in supramolecular chemistry. © 2017 Wiley-VCH Verlag GmbH & Co.

  16. 25th Anniversary Article: Polymer-Particle Composites: Phase Stability and Applications in Electrochemical Energy Storage

    KAUST Repository

    Srivastava, Samanvaya

    2013-12-09

    Polymer-particle composites are used in virtually every field of technology. When the particles approach nanometer dimensions, large interfacial regions are created. In favorable situations, the spatial distribution of these interfaces can be controlled to create new hybrid materials with physical and transport properties inaccessible in their constituents or poorly prepared mixtures. This review surveys progress in the last decade in understanding phase behavior, structure, and properties of nanoparticle-polymer composites. The review takes a decidedly polymers perspective and explores how physical and chemical approaches may be employed to create hybrids with controlled distribution of particles. Applications are studied in two contexts of contemporary interest: battery electrolytes and electrodes. In the former, the role of dispersed and aggregated particles on ion-transport is considered. In the latter, the polymer is employed in such small quantities that it has been historically given titles such as binder and carbon precursor that underscore its perceived secondary role. Considering the myriad functions the binder plays in an electrode, it is surprising that highly filled composites have not received more attention. Opportunities in this and related areas are highlighted where recent advances in synthesis and polymer science are inspiring new approaches, and where newcomers to the field could make important contributions. Polymer-particle composites are used in virtually every field of technology. When the particles approach nanometer dimensions, large interfacial regions are created that can be exploited for applications. The fundamental approaches and bottom-up synthesis strategies for understanding and controlling nanoparticle dispersion in polymers are reviewed. Applications of these approaches for creating polymer-particle composite electrolytes and electrodes for energy storage are also considered. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Refrigeration is one of the main sinks of the German and European electricity consumption and accordingly contributes to worldwide CO{sub 2} emissions. High reduction potentials are envisaged if caloric effects in solid materials are used. The recent discovery of giant entropy changes associated with ferroelastic phase transformations promises higher efficiency. Ferroic transitions enhance the entropy change of magneto-, elasto-, baro-, and electro-caloric effects. Furthermore, because the refrigerant is in a solid state, this technology completely eliminates the need for halofluorocarbon refrigerants having a high global-warming potential. The smaller footprint for operation and the scalable mechanism open up further applications such as cooling of microsystems. While the principal feasibility of magnetocaloric refrigeration is already evident, it requires large magnetic fields (>2 T) which hampers wide industrial and commercial application. It is expected that this obstacle can be overcome by materials with lower hysteresis and by using stress- or electric fields. In order to accelerate research on ferroic cooling, the Deutsche Forschungsgemeinschaft (DFG) decided to establish the priority program SPP 1599 in April 2011. In this article we will address the major challenges for introducing ferroic materials in practical cooling applications: energy efficiency, effect size, and fatigue behavior. Solid state cooling in this sense can be based on the following ''ferroic-caloric'' classes of materials: ferroelastic shape memory alloys, ferromagnetic shape memory alloys, and ferroelectric materials and their possible combinations in materials with ''multicaloric'' effects. The open questions require the interdisciplinary collaboration of material scientists, engineers, physicists, and mathematicians. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co.

    International Plant Proteomics Organization (INPPO) outlined ten initiatives to promote plant proteomics in each and every country. With greater emphasis in developing countries, one of those was to "organize workshops at national and international levels to train manpower and exchange information". This third INPPO highlights covers the workshop organized for the very first time in a developing country, India, at the Department of Botany in University of Delhi on December 26-30, 2013 titled - "1(st) Plant Proteomics Workshop / Training Program" under the umbrella of INPPO India-Nepal chapter. Selected 20 participants received on-hand training mainly on gel-based proteomics approach along with manual booklet and parallel lectures on this and associated topics. In house, as well as invited experts drawn from other Universities and Institutes (national and international), delivered talks on different aspects of gel-based and gel-free proteomics. Importance of gel-free proteomics approach, translational proteomics, and INPPO roles were presented and interactively discussed by a group of three invited speakers Drs. Ganesh Kumar Agrawal (Nepal), Randeep Rakwal (Japan), and Antonio Masi (Italy). Given the output of this systematic workshop, it was proposed and thereafter decided to be organized every alternate year; the next workshop will be held in 2015. Furthermore, possibilities on providing advanced training to those students / researchers / teachers with basic knowledge in proteomics theory and experiments at national and international levels were discussed. INPPO is committed to generating next-generation trained manpower in proteomics, and it would only happen by the firm determination of scientists to come forward and do it. © 2014 WILEY-VCH Verlag GmbH & Co.
