  2. Il senso del lavoro e il suo contesto. Una rilettura di Bartleby lo scrivano di Herman Melville

    Directory of Open Access Journals (Sweden)

    Giuseppe Ruvolo

    2015-09-01

    Full Text Available Attraverso una rilettura critica del noto racconto di Herman Melville Bartleby lo scrivano, viene proposta una chiave di comprensione psico-antropologica delle condotte lavorative, delle relazioni nei contesti lavorativi e delle loro ricadute psicopatologiche. In particolare viene avanzata una lettura che connette i comportamenti e le relazioni lavorative quali esiti della difficoltà dei singoli nella mentalizzazione dei modelli ideologico-culturali che li determinano in un dato momento storico. Viene criticata una lettura, tendenzialmente presente in psicologia clinica e in psicologia del lavoro, in chiave riduttivamente individualistica, la quale attribuisce al singolo presunti deficit psichici ricercando le cause, e gli antecedenti delle condotte disadattive delle formazioni psicopatologiche, nella sola storia personale e individuale dei soggetti.

  3. Dalla Selva alla Cupola: Il trasporto del legname dell’Opera di Santa Maria del Fiore e il suo impiego nel cantiere brunelleschiano

    Full Text Available The essay describes the conditions and process of the supply of timber from the forests managed by Opera of Santa Maria del Fiore during the construction of Brunelleschi’s dome. Furthermore it analyzes the employ of wooden structural elements in support of the building’s masonry and for scaffolding and other temporary apparatuses devised by the Florentine architect. The numerous supply contracts and payments allocated to the haulage contractors reveal the route followed by wooden materials from the forest to building yard and allow the identification of the various types of labor involved in the felling of trees, the preparation of logs and their transport. These documents specify the amount of timber ordered from each hauler and, in some cases, even the linear and volumetric dimensions of the wooden elements ordered by Opera. Such information has permitted the formulation of hypotheses about the structure and dimensions of temporary wooden scaffolding. The number of logs ordered, calculated year by year and related to the successive phases of the construction, reflect the changing requirements of wood for the building process as well as the political and economic situation of the city of Florence (wars, financial crises during the two decades of the construction of the cathedral’s great cupola. The resolutions of the consuls of Wool Guild and the Opera wardens regarding the forest administration testify to the existence of a bureaucratic structure charged with overseeing the woodland heritage. These sources vividly render the difficulties encountered in reconciling the intense exploitation of the forest for economic ends with the livelihood of the local population and, at the same time, with the necessity of ensuring the regeneration of a precious but exhaustible resource entrusted to the Opera’s care.

  4. L'ordine del mondo le simmetrie in fisica da Aristotele a Higgs

    Barone, Vincenzo

    2013-01-01

    Il mondo ci appare come una lunga serie di contingenze locali: ogni fatto accade per ragioni sue e quindi ogni previsione relativa al fatto successivo sembra azzardata. C'è però un altro modo di guardare il mondo, ed è quello fondato sulle regolarità intrinseche, sulle trame ordinate della sua tessitura sottile. In fisica il discorso sulla struttura del mondo giunge a noi addirittura da Anassimandro, ma è con Einstein che si fa strada prepotentemente l'idea di necessità, o di inevitabilità, nel mondo fisico. È con la relatività ristretta, nel 1905, che per la prima volta entra a far parte della fisica il concetto di simmetria come elemento fondamentale della spiegazione del mondo. Da Einstein in poi, il mondo apparirà dotato di una sua struttura intrinseca, che permette lo sviluppo di certe regolarità, mentre ne nega altre, proprio come avviene nel "Castello dei destini incrociati" di Italo Calvino, dove il gioco di incroci tra le storie raccontate dai tarocchi permette alcuni sviluppi narrativi e ...

    Based on extensive preliminary work of the responsible Federal Minister of Labour and Social Affairs, the 'Ordinance to Replace Ordinances under Article 24 of the Irading and Industrial Code' has been issued by the Federal Government on February 27, 1980. This new ordinance also contains the new versions of the Steam Boiler Ordinance, the Pressure Gas Ordinance, the Lift Ordinance, the Ordinance on Electrical Installations in Rooms with High Explosion Hazards, the Acetylene Ordinance, and the Ordinance on Combustible Liquids. Accordingly, these new ordinances all have the same date of issue. Coming into force on July 1, 1980, they will replace six ordinances for plants to be licensed. The same applies to the pertinent general administrative regulations. (orig.) [de

    1993-01-01

    Niels Bohr è una figura centrale nella fisica del Novecento, padre fondatore della teoria atomica e della meccanica quantistica. La storia della sua vita, ricca e piena anche sul piano affettivo e personale, non può dunque ridursi a un resoconto dei suoi successi scientifici e Pais, allievo e poi amico di Bohr, ne è perfettamente consapevole. Il libro si sviluppa su vari piani: capitoli strettamente biografici o storico-scientifici si alternano a discussioni sulle idee di Bohr in campo politico e filosofico, sui suoi rapporti con Einstein, sul suo ruolo nei drammatici anni della guerra e su molti altri aspetti della vicenda umana.

    Full Text Available Private letters, as well as introductions to the major historical works of the 1820s and '30s, show how Sismondi’s historiography might appear to be marginal for his times, but also that it was the product of a conscious choice. By means of his militant as well as scientific approach, Sismondi studied the masters of historiography belonging to the 18th and 19th centuries. Nonetheless, he kept faith with eccentric theories in the fields of political economy and constitutionalism. These theories made a great contribution towards distinguishing Sismondi’s historiography as an exception vis-à-vis the historiographical mainstream of those decades.

  9. Il trauma: storia di un concetto e del suo significato

    2012-09-01

    Full Text Available History teaches us that human beings have always suffered from violent irruptions in their psyche and that this irruption has lasting effects, as perturbation of dreams. During the last two centuries, the concepts of traumatic neurosis and war neurosis were pointed out; then, in the last decades, these concepts’ definition has been challenged for reasons of psychoanalytic resonance, and the American DSM proposed to replace them with the new concept of posttraumatic stress state. However, it has been pointed out that not all the clinical cases observed from then on after a trauma have evolved in a traumatic neurosis. In the light of these remarks, and going against the tide, the francophone school introduced the use of the generic denomination post-traumatic syndrome . It has the merit of stating explicitly the psychological nature of the trauma and it can cover all the stages of traumatic pathology: the immediate, the post-immediate, and the chronic. Moreover, among the cases of the latter kind, it allows to understand well also the cases structured as traumatic neurosis, which fit well into the limiting criteria of PTSD, as well as all the other cases which are atypical or not clearly classifiable.

These results demonstrate that lactic acid bacteria has preventive effects on mouse constipation and LF-Suo demonstrated the best functional activity.

  14. La città sotterranea e il suo ruolo nella mobilità urbana

    Directory of Open Access Journals (Sweden)

    Giuseppe Mazzeo

    2008-12-01

    Full Text Available La città sotterranea è un elemento fondamentale nella struttura urbana. Soprattutto nelle grandi città essa assume connotazioni rilevanti nella pianificazione urbana in considerazione del fatto che rappresenta una risorsa e il suo impiego può incidere significativamente sull’efficienza del sistema urbano. Alcune città, a causa soprattutto della rigidità del clima, hanno progettato città sotterranee di grande complessità funzionale; esempi significativi sono Montreal, Toronto e altre città del Nord America. In Europa occidentale le realizzazioni associabili al concetto di città sotterranea sono più limitate e sono relative soprattutto alla realizzazione di infrastrutture per la mobilità urbana, come le reti metropolitane, i passanti ferroviari, i tunnel stradali e i parcheggi sotterranei. La funzione primaria di questi spazi è la riduzione e lo spostamento dalla superficie di quote di traffico e la trasformazione di ampie parti della città in aree verdi o in aree a maggiore qualità ambientale. In ogni modo è possibile sostenere che l’uso degli spazi sotterranei è ormai entrato a far parte della vita delle città moderne. L’articolo analizza alcuni dei fattori principali nella costruzione di questi spazi urbani; i costi e i benefici dell’uso di spazi sotterranei sono messi in relazione con gli aspetti psicologici e con la costruzione di modelli per la previsione dei percorsi degli utenti. La seconda parte dell’articolo mostra alcuni casi studio evidenziando le diverse necessità che hanno spinto e hanno guidato verso la scelta degli spazi sotterranei; una analisi più dettagliata è svolta sul caso di Montreal, che può essere considerato archetipo della citta sotterranea.

  2. ON CHINESE ORDINAL CONSTRUCTIONS

    Directory of Open Access Journals (Sweden)

    Hui-Chin Tsai

    2011-06-01

    Full Text Available A Chinese ordinal construction in the form [di + Num + Cl + N] is ambiguous between a definite construal and an indefinite quantity construal. The morpheme di heads a DP, and the two readings of the ordinal expression can be attributed to the lexical ambiguity of the morpheme di. On the one hand, if the event is realized once, and there is an ordered set of objects in a single space within which the context of a sentence can verify a presupposed referential existence for the denotation of ordinal phrases, di is a [+strong] determiner giving rise to a definite reading. On the other hand, if the event is carried out more than once, no such an ordered set of objects is present in a single space, and the context of a sentence cannot verify a presupposed referential existence for the denotation of ordinal phrases, di is a [-strong] determiner with an additive function and results in an indefinite quantity reading.

    This Ordinance lays down the licensing system for activities in Switzerland involving possible exposure to radiation, with the exception of nuclear installations, fuels and radioactive waste which, under the 1959 Atomic Energy Act, are subject to licensing. The Ordinance applies to the production, handling, use, storage, transport, disposal, import and export of radioactive substances and devices and articles containing them; and generally to any activity involving hazards caused by ionizing radiation. The Federal Public Health Office is the competent authority for granting licences. Provision is also made for the administrative conditions to be complied with for obtaining such licences as well as for technical measures required when engaged in work covered by the Ordinance. This consolidated version of the Ordinance contains all the successive amendments up to 26 September 1988. (NEA) [fr

    1983-01-01

    This commentary, presented as volume 2 of the Deutsches Strahlenschutzrecht (German legislation on radiation protection) deals with the legal provisions of the ordinance on the protection against harmful effects of X-radiation (X-ray Ordinance - RoeV), of March 1, 1973 (announced in BGBl.I, page 173), as amended by the ordinance on the protection against harmful effects of ionizing radiation, of October 13, 1976 (announced in BGBl. I, page 2905). Thus volume 2 completes the task started with volume 1, namely to present a comprehensive view and account of the body of laws governing radiation protection, a task which was thought useful as developments in the FRG led to regulations being split up into the X-ray Ordinance, and the Radiation Protection Ordinance. In order to present a well-balanced commentary on the X-ray Ordinance, it was necessary to discuss the provisions both from the legal and the medical point of view. This edition takes into account the Fourth Public Notice of the BMA (Fed. Min. of Labour and Social Affairs) concerning the implementation of the X-ray Ordinance of January 4, 1982, as well as court decisions and literature published in this field, until September 1982. In addition, the judgment of the Federal Constitutional Court, dated October 19, 1982, concerning the voidness of the law on government liability, and two decisions by the Federal High Court, dated November 23, 1982, concerning the right to have insight into medical reports - of great significance in practice - have been considered. This commentary therefore is up to date with current developments. (orig.) [de

    This paper introduces a concept of inequality comparisons with ordinal bivariate categorical data. In our model, one population is more unequal than another when they have common arithmetic median outcomes and the first can be obtained from the second by correlation-increasing switches and....../or median-preserving spreads. For the canonical 2 × 2 case (with two binary indicators), we derive a simple operational procedure for checking ordinal inequality relations in practice. As an illustration, we apply the model to childhood deprivation in Mozambique....

    This paper introduces a concept of inequality comparisons with ordinal bivariate categorical data. In our model, one population is more unequal than another when they have common arithmetic median outcomes and the first can be obtained from the second by correlationincreasing switches and/or median......-preserving spreads. For the canonical 2x2 case (with two binary indicators), we derive a simple operational procedure for checking ordinal inequality relations in practice. As an illustration, we apply the model to childhood deprivation in Mozambique....

    The widespread interest in meteorology is mostly driven by the fact that weather affects our daily life, extending its influence beyond the mere economical impact. Despite this strong attention to meteorology it is seen quite differently from other scientific activities like, for instance, classical physics to which it is generally, although often unappropriately, associated. This work tries to highlight the peculiar epistemologic approach to modern meteorology, through t...

    This Second Ordinance for Amendment of the Radiation Protection Ordinance has modified the most important legal provisions supplementing the Atomic Energy Act. But looking closer at the revised version of the Ordinance, many an amendment turns out to be just a new facade on the old brickwork. The article critically reviews the most important amendments, stating that the main principles have remained untouched, and discussing the modification of limiting values, the definition of regulatory scopes, the new meaning of the term 'wastes containing nuclear fuel', and the regulatory scope of provisions governing radioactive substances and their medical applications.

  13. Tree Ordination as Invented Tradition

    2012-01-01

    Full Text Available The symbolic ordination of trees as monks in Thailand is widely perceived in Western scholarship to be proof of the power of Buddhism to spur ecological thought. However, a closer analysis of tree ordination demonstrates that it is not primarily about Buddhist teaching, but rather is an invented tradition based on the sanctity of Thai Buddhist symbols as well as those of spirit worship and the monarchy. Tree ordinations performed by non-Buddhist minorities in Thailand do not demonstrate a religious commitment but rather a political one.

    Recent work on quantization in rotating co-ordinates showed that no radiation would be seen by an observer rotating with a constant angular speed. This work used a Galilean-type co-ordinate transformation. We show that the same result holds for a Lorentz-type co-ordinate system, in spite of the fact that the metric has a co-ordinate singularity at rΩ = 1. Further, we are able to define positive and negative energy modes for a particular case of a non-static, non-stationary metric. (author)

    Full Text Available Irony and satire, two complex phenomena, find their respective places in the dramatic works of Max Frisch (1911–1991, a Swiss playwright and novelist and have gone through many changes gaining on different meanings, depending on the socio-cultural context, dominant literary and philosophical theories of a certain period of time in which they were analyzed and recognized as such. The aim of this paper is to show that Max Frisch, a 20th century intellectual who witnessed the major political, cultural and social changes of the second half of the 20th century in Europe and worldwide, uses irony and satire for coping with the reality and challenges of the time he lived in. Keywords: Max Frisch, dramatic work, irony, satire, 20th centuryNeutralna pozicija koju je Švicarska imala za vrijeme Drugoga svjetskog rata, a zbog koje je ostala pošteđena ratnih zbivanja te otvorenost klasičnim, ali i suvremenim europskim i svjetskim književnim te kazališnim utjecajima, stvorili su pozitivno ozračje za dobru, aktualnu i suvremenu švicarsku dramsku književnost na njemačkom jeziku nakon 1945. godine čiji predstavnik postaje jedan od najvećih švicarskih književnika, Max Frisch (1911–1991.

    The SuoQuan formulae containing Fructus Alpiniae Oxyphyllae has been used to combat the urinary incontinence symptoms including frequency, urgency and nocturia for hundreds of years in China. However, the chemical information was not well characterized. The quality control marker constituent only focused on one single compound in the current Chinese Pharmacopeia. Hence it is prudent to identify and quantify the main constituents in this herbal product. This study aimed to analyze the main constituents using ultra-fast performance liquid chromatography coupled to tandem mass spectrometry (UFLC-MS/MS). Fourteen phytochemicals originated from five chemical classes constituents were identified by comparing the molecular mass, fragmentation pattern and retention time with those of the reference standards. A newly developed UFLC-MS/MS was validated demonstrating that the new assay was valid, reproducible and reliable. This method was successfully applied to simultaneously quantify the fourteen phytochemicals. Notably, the content of these constituents showed significant differences in three pharmaceutical preparations. The major constituent originated from each of chemical class was isolinderalactone, norisoboldine, nootkatone, yakuchinone A and apigenin-4',7-dimethylther, respectively. The variation among these compounds was more than 1000 times. Furthermore, the significant content variation between the two different Suoquan pills was also observed. The proposed method is sensitive and reliable; hence it can be used to analyze a variety of SuoQuan formulae products produced by different pharmaceutical manufacturers.

    Oteri, F.

    2008-12-01

    Due to increased energy demand in the United States, rural communities with limited or no experience with wind energy now have the opportunity to become involved in this industry. Communities with good wind resources may be approached by entities with plans to develop the resource. Although these opportunities can create new revenue in the form of construction jobs and land lease payments, they also create a new responsibility on the part of local governments to ensure that ordinances will be established to aid the development of safe facilities that will be embraced by the community. The purpose of this report is to educate and engage state and local governments, as well as policymakers, about existing large wind energy ordinances. These groups will have a collection of examples to utilize when they attempt to draft a new large wind energy ordinance in a town or county without existing ordinances.

  20. Dimensionality Reduction in Multiple Ordinal Regression.

    Zeng, Jiabei; Liu, Yang; Leng, Biao; Xiong, Zhang; Cheung, Yiu-Ming

    2017-10-10

    Supervised dimensionality reduction (DR) plays an important role in learning systems with high-dimensional data. It projects the data into a low-dimensional subspace and keeps the projected data distinguishable in different classes. In addition to preserving the discriminant information for binary or multiple classes, some real-world applications also require keeping the preference degrees of assigning the data to multiple aspects, e.g., to keep the different intensities for co-occurring facial expressions or the product ratings in different aspects. To address this issue, we propose a novel supervised DR method for DR in multiple ordinal regression (DRMOR), whose projected subspace preserves all the ordinal information in multiple aspects or labels. We formulate this problem as a joint optimization framework to simultaneously perform DR and ordinal regression. In contrast to most existing DR methods, which are conducted independently of the subsequent classification or ordinal regression, the proposed framework fully benefits from both of the procedures. We experimentally demonstrate that the proposed DRMOR method (DRMOR-M) well preserves the ordinal information from all the aspects or labels in the learned subspace. Moreover, DRMOR-M exhibits advantages compared with representative DR or ordinal regression algorithms on three standard data sets.

  1. Recent developments in discrete ordinates electron transport

    International Nuclear Information System (INIS)

    Morel, J.E.; Lorence, L.J. Jr.

    1986-01-01

    The discrete ordinates method is a deterministic method for numerically solving the Boltzmann equation. It was originally developed for neutron transport calculations, but is routinely used for photon and coupled neutron-photon transport calculations as well. The computational state of the art for coupled electron-photon transport (CEPT) calculations is not as developed as that for neutron transport calculations. The only production codes currently available for CEPT calculations are condensed-history Monte Carlo codes such as the ETRAN and ITS codes. A deterministic capability for production calculations is clearly needed. In response to this need, we have begun the development of a production discrete ordinates code for CEPT calculations. The purpose of this paper is to describe the basic approach we are taking, discuss the current status of the project, and present some new computational results. Although further characterization of the coupled electron-photon discrete ordinates method remains to be done, the results to date indicate that the discrete ordinates method can be just as accurate and from 10 to 100 times faster than the Monte Carlo method for a wide variety of problems. We stress that these results are obtained with standard discrete ordinates codes such as ONETRAN. It is clear that even greater efficiency can be obtained by developing a new generation of production discrete ordinates codes specifically designed to solve the Boltzmann-Fokker-Planck equation. However, the prospects for such development in the near future appear to be remote

  3. The new German radiation protection ordinance

    International Nuclear Information System (INIS)

    Pfeffer, W.; Weimer, G.

    2003-01-01

    According to European law, the Basic Safety Standards (BSS) published by the European Council in 1996 and the Council Directive on health protection of individuals against dangers of ionising radiation in relation to medical exposure had to be transferred into national law within due time. In 2001 the new Ordinance for the Implementation of the Euratom Guidelines on Radiation Protection] was published, which replaces the old Radiation Protection Ordinance. The new German Ordinance adapts the European Directive to German law, covering the general principles but even giving more details in many fields of radiation protection. The BSS scope certainly is much broader than the prescriptions important for the field of radiation protection in nuclear power plants. According to the scope of this workshop on occupational exposure in nuclear power plants - and as the BSS most probably will be quite familiar to all of you - after a short general overview on relevant contents of the German Ordinance, this presentation will focus on the main issues important in the operation of NPP and especially on some areas which may give rise to necessary changes caused by the new Ordinance.

However, given the major objective of estimating prognosis on an ordinal scale, we argue that the rival staging system candidates should be compared...... on their ability to predict outcome. We sought to outline an algorithm that would compare two rival ordinal systems on their predictive ability. RESULTS: We devised an algorithm based largely on the concordance index, which is appropriate for comparing two models in their ability to rank observations. We...... demonstrate our algorithm with a prostate cancer staging system example. CONCLUSION: We have provided an algorithm for selecting the preferred staging system based on prognostic accuracy. It appears to be useful for the purpose of selecting between two ordinal prediction models....

Lasciati alle spalle i confini sicuri della Terra e del Sistema solare, assistiamo a un'esplosione continua di fenomeni inaspettati. L'universo si svela nel suo continuo mutamento, cresce in fascino e complessità via via che ci addentriamo nei suoi spazi profondi. Tramite esempi semplici, aneddoti umoristici e una prosa cristallina, Vishnu Narkilar racconta l'emozione di fronte alle sorprese del cosmo. Le "sette meraviglie" sono i fenomeni misteriosi che si nascondono dietro le stelle che punteggiano il cielo, una schiera di eventi spettacolari che per secoli hanno sfidato la curiosità umana ed eluso ogni spiegazione.

  14. Multilevel moderated mediation model with ordinal outcome.

    2018-05-10

    Although increasingly complex models have been proposed in mediation literature, there is no model nor software that incorporates the multiple possible generalizations of the simple mediation model jointly. We propose a flexible moderated mediation model allowing for (1) a hierarchical structure of clustered data, (2) more and possibly correlated mediators, and (3) an ordinal outcome. The motivating data set is obtained from a European study in nursing research. Patients' willingness to recommend their treating hospital was recorded in an ordinal way. The research question is whether such recommendation directly depends on system-level features in the organization of nursing care, or whether these associations are mediated by 2 measurements of nursing care left undone and possibly moderated by nurse education. We have developed a Bayesian approach and accompanying program that takes all the above generalizations into account. Copyright © 2018 John Wiley & Sons, Ltd.

    Favorite, J.A.; Stacey, W.M.

    1999-01-01

    A self-consistent nodal approximation method for computing discrete ordinates neutron flux distributions has been developed from a variational functional for neutron transport theory. The advantage of the new nodal method formulation is that it is self-consistent in its definition of the homogenized nodal parameters, the construction of the global nodal equations, and the reconstruction of the detailed flux distribution. The efficacy of the method is demonstrated by two-dimensional test problems

    2017-05-01

    We introduce the multi-dimensional ordinal arrays complexity as a generalized approximation of the ordinal Komogorov-Sinai entropy. The ordinal arrays entropy (OAE) is defined as the Shannon entropy of a series of m-ordinal patterns encoded symbols, while the ordinal arrays complexity (OAC) is defined as the differential of the OAE with respect to m. We theoretically establish that the OAC provides a better estimate of the complexity measure for short length time series. Simulations were carried out using discrete maps, and confirm the efficiency of the OAC as complexity measure from a small data set even in a noisy environment.

  17. Scoring ordinal variables for constructing composite indicators

    2013-05-01

    Full Text Available In order to provide composite indicators of latent variables, for example of customer satisfaction, it is opportune to identify the structure of the latent variable, in terms of the assignment of items to the subscales defining the latent variable. Adopting the reflective model, the impact of four different methods of scoring ordinal variables on the identification of the true structure of latent variables is investigated. A simulation study composed of 5 steps is conducted: (1 simulation of population data with continuous variables measuring a two-dimensional latent variable with known structure; (2 draw of a number of random samples; (3 discretization of the continuous variables according to different distributional forms; (4 quantification of the ordinal variables obtained in step (3 according to different methods; (5 construction of composite indicators and verification of the correct assignment of variables to subscales by the multiple group method and the factor analysis. Results show that the considered scoring methods have similar performances in assigning items to subscales, and that, when the latent variable is multinormal, the distributional form of the observed ordinal variables is not determinant in suggesting the best scoring method to use.

    ABSTRACT: Today we are facing the threat of a new modus pensandi, which has already achieved its objectives in Europe and in Italy: the gender theories. The latter are intended to assert the superiority of culture over nature, aiming for the recognition of the third kind. In Europe they have already succeeded in their aim, while in Italy we need to reflect more on the term person, focusing on the fact that culture must lie in the nature, only certainty of our existence. Hopefully, starting from Italy, also Europe returns 'his steps'.

Una disciplina che, in Italia, vede la sua nascita a partire dall’ultimo ventennio del secolo scorso e che lo studioso, recentemente scomparso, ha contribuito a delineare con precisione. Il volume La macchina della pittura è sicuramente il suo contributo più innovativo, più sistematico e anc’oggi attuale. All’epoca in cui è stato pubblicato, nel 1985, lanciava una duplice sfida: alla storia dell’arte tradizionale e alla semiotica. Alla prima perché imponeva un altro tipo di sguardo, capace di decifrare il modo in cui attraverso la forma è costruito il senso pittorico. Alla semiotica perché dimostra come la pittura sia in grado di produrre senso e addirittura contenga al suo interno i meccanismi per interpretarla.

    an ordinal model, in which the response categories are ordered cyclically, that can account for the McGurk illusion. We compare this model to the Fuzzy Logical Model of Perception (FLMP), which is not an ordinal model, based on an original data set. While the FLMP fitted the data better than the ordinal...... model it also employed 30 free parameters where the ordinal model needed only 14. Testing the predictive power of the models using a form of cross-validation we found that, although both models performed rather poorly, the ordinal model performed better than the FLMP. Based on these findings we suggest...... that ordinal models generally have greater predictive power because they are constrained by a priori information about the adjacency of phonetic categories....

The solution was the cooperative development of an ordinance to limit the discharge of cadmium. Because the dischargers acted responsibly to comply with the ordinance, the ordinance succeeded in achieving its objective of significantly reducing the cadmium loading to the municipal sewerage system and subsequently reducing the cadmium concentration in Milorganite fertilizer

    We develop an ordinal method for making welfare comparisons between populations with multidimensional discrete well-being indicators observed at the micro level. The approach assumes that, for each well-being indicator, the levels can be ranked from worse to better; however, no assumptions are made...... about relative importance of any dimension nor about complementarity/substitutability relationships between dimensions. The method is based on the concept of multidimensional first order dominance. We introduce a rapid and reliable algorithm for empirically determining whether one population dominates...... another on the basis of available binary indicators by drawing upon linear programming theory. These approaches are applied to household survey data from Vietnam and Mozambique with a focus on child poverty comparisons over time and between regions....

    2012-01-01

    Full Text Available Exploratory factor analysis is a widely used statistical technique in the social sciences. It attempts to identify underlying factors that explain the pattern of correlations within a set of observed variables. A statistical software package is needed to perform the calculations. However, there are some limitations with popular statistical software packages, like SPSS. The R programming language is a free software package for statistical and graphical computing. It offers many packages written by contributors from all over the world and programming resources that allow it to overcome the dialog limitations of SPSS. This paper offers an SPSS dialog written in theR programming language with the help of some packages, so that researchers with little or no knowledge in programming, or those who are accustomed to making their calculations based on statistical dialogs, have more options when applying factor analysis to their data and hence can adopt a better approach when dealing with ordinal, Likert-type data.

    Evaluation of cardiotocogram (CTG) is a standard approach employed during pregnancy and delivery. But, its interpretation requires high level expertise to decide whether the recording is Normal, Suspicious or Pathological. Therefore, a number of attempts have been carried out over the past three decades for development automated sophisticated systems. These systems are usually (multiclass) classification systems that assign a category to the respective CTG. However most of these systems usually do not take into consideration the natural ordering of the categories associated with CTG recordings. In this work, an algorithm that explicitly takes into consideration the ordering of CTG categories, based on binary decomposition method, is investigated. Achieved results, using as a base classifier the C4.5 decision tree classifier, prove that the ordinal classification approach is marginally better than the traditional multiclass classification approach, which utilizes the standard C4.5 algorithm for several performance criteria.

    Full Text Available Ordinal logistic regression models are used to predict the dependent variable, when dependent variable is of ordinal type in both the situation for single level and multilevel. The most used model for ordinal regression is the Proportional Odd (PO model which assumes that the effect of the each predictor remains same for each category of the response variable. To estimate the wealth index of household in the province Punjab the proportional odds model is used. The wealth index is an order categorical dependent variable having five categories. The data MICS (2014, a multiple indicator cluster survey conduct by Punjab bureau of statistics was used in this article. The data was recorded at different level such as individual level (household level, district level and division level. The secondary data MICS contains a sample of 41413 household collected from both rural and urban areas of the province Punjab. In the present study analysis were made for single level (household level and two levels (division level. After fitting the proportional odds model for the single level the proportionality assumption is tested by the brand test whose results suggest that all the predictors fulfill assumption of proportional odds. The significance value suggests that all the predictors have significant effect on the wealth index. The variation due to division level was estimated by two level ordinal logistic regression equal to 5.842, and the Intra Class Correlation ICC is equal to 0.6397 which show that 63.97% of total variation is due to division level.

Lo studio delle emissioni monetarie conferma il suo testo e permette di dedurre alcuni aspetti in merito agli eventi che portarono Godas al potere nell'isola e che non sono stati narrati dallo storico palestino. Ciò permette di correggere un'inesatta interpretazione dei fatti data dagli storici sardi, i quali, basandosi sulla traduzione latina invece che sull'originale greco, scrivono che Godas fu inviato in Sardegna dal re vandalo Gelamir: invece il suo ruolo nell'isola fu necessariamente importante già durante il regno di Hilderico, il suo predecessore.

    Several observations suggest that overlearned ordinal categories (e.g., letters, numbers, weekdays, months) are processed differently than non-ordinal categories in the brain. In synesthesia, for example, anomalous perceptual experiences are most often triggered by members of ordinal categories (Rich et al., 2005; Eagleman, 2009). In semantic dementia, the processing of ordinal stimuli appears to be preserved relative to non-ordinal ones (Cappelletti et al., 2001). Moreover, ordinal stimuli o...

  19. Semi-supervised learning for ordinal Kernel Discriminant Analysis.

    2016-12-01

    Ordinal classification considers those classification problems where the labels of the variable to predict follow a given order. Naturally, labelled data is scarce or difficult to obtain in this type of problems because, in many cases, ordinal labels are given by a user or expert (e.g. in recommendation systems). Firstly, this paper develops a new strategy for ordinal classification where both labelled and unlabelled data are used in the model construction step (a scheme which is referred to as semi-supervised learning). More specifically, the ordinal version of kernel discriminant learning is extended for this setting considering the neighbourhood information of unlabelled data, which is proposed to be computed in the feature space induced by the kernel function. Secondly, a new method for semi-supervised kernel learning is devised in the context of ordinal classification, which is combined with our developed classification strategy to optimise the kernel parameters. The experiments conducted compare 6 different approaches for semi-supervised learning in the context of ordinal classification in a battery of 30 datasets, showing (1) the good synergy of the ordinal version of discriminant analysis and the use of unlabelled data and (2) the advantage of computing distances in the feature space induced by the kernel function.

    A method is described for generating electron cross sections that are compatible with standard discrete ordinates codes without modification. There are many advantages of using an established discrete ordinates solver, e.g. immediately available adjoint capability. Coupled electron-photon transport capability is needed for many applications, including the modeling of the response of electronics components to space and man-made radiation environments. The cross sections have been successfully used in the DORT, TWODANT and TORT discrete ordinates codes. The cross sections are shown to provide accurate and efficient solutions to certain multidimensional electronphoton transport problems

In addition to its overall competence in respect of radiation safety, the Centre will carry out research into and supervise the health effects of radiation and maintain a laboratory for national measurements in that field. The Ordinance also sets out the Centre's organisation chart and the staff duties [fr

  3. Open Method of Co-Ordination for Demoi-Cracy?

    Under which conditions does the open method of co-ordination match the standards for demoi-cracy? To answer this question, we need some explicit standards about demoi-cracy. In fact, open co-ordination serves three different but interrelated purposes in European Union policy: to facilitate...... convergence; to support learning processes; and to encourage exploration of policy innovation. By intersecting standards and purposes, we find open co-ordination is neither inherently ‘good’ nor ‘bad’ for demoi-cracy, as it depends on how it has been put into practice. Therefore, we qualify the answer...

    This article focuses on the tensions, within which the drama about the admittance of women to the ordination to ministry in the Danish folkchurch was played out: church - state; church - people; Catholic - Lutheran; sacred - secular; hierarchical - democratic; feminine - human. Until the ordination...... of women was legislatively made possible on June 4 1947, the drama was played out within a church-state-complex, and some of the players tried to discern between the ministry, to which women i special functions could be admitted (for example pastors in a women's prison), and the ordination, which...

    2000-01-01

    Il libro mostra come la gravitazione abbia un ruolo determinante nei fenomeni cosmici che più ci impressionano, da quelli relativamente vicini alla nostra esperienza (come la formazione delle stelle) a quelli meno intuibili (come la formazione dei buchi neri), alla struttura dell'Universo nel suo insieme. Oltre a spiegare, in modo qualitativo, concetti come la geometria dello spazio-tempo, la relatività del tempo e i coni di luce, l'autore formula un'ipotesi innovativa tendente a spiegare l'origine della gravitazione e con essa quella dei fenomeni circondati ancora da un alone di mistero: la materia oscura dell'Universo e il destino della materia alla fine del collasso gravitazionale.

    The last major reform of the German Radiation Protection Ordinance took place on July 26, 2001. The 'First Ordinance Amending Ordinances in Radiation Protection Law' now proposed is to cover primarily the necessary changes and supplements resulting from experience in the execution of the ordinances. They mainly relate to these issues: (1) the scope of application of the Radiation Protection Ordinance and of the x-ray Ordinance in medical research (2) the scope of application of the Radiation Protection Ordinance and the -ray Ordinance in unjustified types of activities (3) electronic communication ('e-government') (4) changes in the provisions about permits and announcements in the Radiation Protection Ordinance (5) new clearance levels in the Radiation Protection Ordinance (6) cross-border transports of 'NORM' materials (7) other changes in the scope of application of the Radiation Protection Ordinance (8) other changes in the x-ray area.

    We describe a new discrete ordinates nodal method for the two-dimensional transport equation. We solve the discrete ordinates equation analytically after the source term is projected and represented in polynomials. The method is applied to two fast reactor benchmark problems and compared with the TWOHEX code. The results indicate that the present method accurately predicts not only multiplication factor but also flux distribution

  10. Overstatement in happiness reporting with ordinal, bounded scale.

    There are various methods by which people can express subjective evaluations quantitatively. For example, happiness can be measured on a scale from 1 to 10, and has been suggested as a measure of economic policy. However, there is resistance to these types of measurement from economists, who often regard welfare to be a cardinal, unbounded quantity. It is unclear whether there are differences between subjective evaluation reported on ordinal, bounded scales and on cardinal, unbounded scales. To answer this question, we developed functional magnetic resonance imaging experimental tasks for reporting happiness from monetary gain and the perception of visual stimulus. Subjects tended to report higher values when they used ordinal scales instead of cardinal scales. There were differences in neural activation between ordinal and cardinal reporting scales. The posterior parietal area showed greater activation when subjects used an ordinal scale instead of a cardinal scale. Importantly, the striatum exhibited greater activation when asked to report happiness on an ordinal scale than when asked to report on a cardinal scale. The finding that ordinal (bounded) scales are associated with higher reported happiness and greater activation in the reward system shows that overstatement bias in happiness data must be considered.

  13. Local zoning ordinances -- how they limit or restrict mining

    International Nuclear Information System (INIS)

    Ingram, H.

    1991-01-01

    Local regulation of mining by zoning has taken place for a long period of time. The delegation to local municipalities of land use planning, zoning and nuisance abatement authority which may affect mining by state governments has been consistently upheld by appellate courts as valid exercises of the police power. Recently, mine operators and mineral owners have been confronted by efforts of local municipalities, often initiated by anti-mining citizen's groups, to impose more stringent restrictions on mining activities within their borders. In some situations, existing ordinances are being enforced for the first time, in others, new ordinances have been adopted without much awareness or involvement by the public. Enforced to the letter, these ordinances can sterilize large blocks of mineable reserves open-quotes operatingclose quotes or performance standards in excess of SMCRA-based regulatory requirements. It is fair to say that investigation of the potential impacts of local zoning and other related ordinances is essential in the planning for the expansion of existing operations or for new operations. There may be new rules in the game. This paper identifies problem areas in typical open-quotes modernclose quotes ordinances and discusses legal and constitutional issues which may arise by their enforcement in coal producing regions

A primary ordination of the woody plants, based on Bray & Curtis’s (1957 method, was carried out using 60 quadrats. Four stand noda were delimited and another four noda within a secondary ordination of a cluster of quadrats which could not be interpreted within the primary ordination. Edaphic and atmospheric moisture conditions and slope aspect were proposed as the main site factors correlated with species performance. Tables of density, local frequency and constancy for species occurring in each nodum were drawn up.

  15. MODELLING OF ORDINAL TIME SERIES BY PROPORTIONAL ODDS MODEL

    Directory of Open Access Journals (Sweden)

    Serpil AKTAŞ ALTUNAY

    2013-06-01

    Full Text Available Categorical time series data with random time dependent covariates often arise when the variable categories are assigned as categorical. There are several other models that have been proposed in the literature for the analysis of categorical time series. For example, Markov chain models, integer autoregressive processes, discrete ARMA models can be utilized for modeling of categorical time series. In general, the choice of model depends on the measurement of study variables: nominal, ordinal and interval. However, regression theory is successful approach for categorical time series which is based on generalized linear models and partial likelihood inference. One of the models for ordinal time series in regression theory is proportional odds model. In this study, proportional odds model approach to ordinal categorical time series is investigated based on a real air pollution data set and the results are discussed.

    Full Text Available A log-linear analysis is a method providing a comprehensive scheme to describe the association for categorical variables in a contingency table. The log-linear model specifies how the expected counts depend on the levels of the categorical variables for these cells and provide detailed information on the associations. The aim of this paper is to present theoretical, as well as empirical, aspects of ordinal log-linear models used for contingency tables with ordinal variables. We introduce log-linear models for ordinal variables: linear-by-linear association, row effect model, column effect model and RC Goodman’s model. Algorithm, advantages and disadvantages will be discussed in the paper. An empirical analysis will be conducted with the use of R.

    This Ordinance on radiation protection lays down the licensing system for activities in Switzerland involving possible exposure to radiation, with the exception of nuclear installations, fuels and radioactive waste which, under the 1959 Atomic Energy Act, are subject to licensing. The Ordinance applies to the production, handling, use, storage, transport, disposal, import and export of radioactive substances and devices and articles containing them; and generally to any activity involving hazards caused by ionizing radiation. The Federal Public Health Service is the competent authority for granting licences. Provision is also made for the administrative conditions to be complied with for obtaining such licences as well as for technical measures required when engaged in work covered by the Ordinance.

  18. Co-ordination of heterovalent cation impurities in molten salts

    International Nuclear Information System (INIS)

    1982-01-01

    The local liquid structure around heterovalent cation impurities in molten chlorides is discussed in relation to spectroscopic data on solutions of transition metal ions. A tightly packed, low co-ordination shell is shown to be favoured by Coulomb ionic interactions for physically reasonable values of the size of the impurity. A competition between these forces and ''crystal field'' interactions favouring octahedral co-ordination is thus to be expected for many transition metal ions, as suggested by Gruen and McBeth. The transition observed for some transition metal ions from higher to lower co-ordination with increasing temperature is attributed primarily to entropy differences, that are roughly estimated in a solid-like model.

  19. Space in Numerical and Ordinal Information: A Common Construct?

    Directory of Open Access Journals (Sweden)

    Philipp Alexander Schroeder

    2017-12-01

    Full Text Available Space is markedly involved in numerical processing, both explicitly in instrumental learning and implicitly in mental operations on numbers. Besides action decisions, action generations, and attention, the response-related effect of numerical magnitude or ordinality on space is well documented in the Spatial-Numerical Associations of Response Codes (SNARC effect. Here, right- over left-hand responses become relatively faster with increasing magnitude positions. However, SNARC-like behavioral signatures in non-numerical tasks with ordinal information were also observed and inspired new models integrating seemingly spatial effects of ordinal and numerical metrics. To examine this issue further, we report a comparison between numerical SNARC and ordinal SNARC-like effects to investigate group-level characteristics and individual-level deductions from generalized views, i.e., convergent validity. Participants solved order-relevant (before/after classification and order-irrelevant tasks (font color classification with numerical stimuli 1-5, comprising both magnitude and order information, and with weekday stimuli, comprising only ordinal information. A small correlation between magnitude- and order-related SNARCs was observed, but effects are not pronounced in order-irrelevant color judgments. On the group level, order-relevant spatial-numerical associations were best accounted for by a linear magnitude predictor, whereas the SNARC effect for weekdays was categorical. Limited by the representativeness of these tasks and analyses, results are inconsistent with a single amodal cognitive mechanism that activates space in mental processing of cardinal and ordinal information alike. A possible resolution to maintain a generalized view is proposed by discriminating different spatial activations, possibly mediated by visuospatial and verbal working memory, and by relating results to findings from embodied numerical cognition.

  20. Projected discrete ordinates methods for numerical transport problems

    Energy Technology Data Exchange (ETDEWEB)

    Larsen, E.W.

    1985-01-01

    A class of Projected Discrete-Ordinates (PDO) methods is described for obtaining iterative solutions of discrete-ordinates problems with convergence rates comparable to those observed using Diffusion Synthetic Acceleration (DSA). The spatially discretized PDO solutions are generally not equal to the DSA solutions, but unlike DSA, which requires great care in the use of spatial discretizations to preserve stability, the PDO solutions remain stable and rapidly convergent with essentially arbitrary spatial discretizations. Numerical results are presented which illustrate the rapid convergence and the accuracy of solutions obtained using PDO methods with commonplace differencing methods.

    Aschenbrenner, T.; Monetti, R.; Amigó, J. M.; Bunk, W.

    2013-06-01

    Ordinal symbolic dynamics has developed into a valuable method to describe complex systems. Recently, using the concept of transcripts, the coupling behaviour of systems was assessed, combining the properties of the symmetric group with information theoretic ideas. In this contribution, methods from the field of ordinal symbolic dynamics are applied to the characterisation of audio data. Coupling complexity between frequency bands of solo violin music, as a fingerprint of the instrument, is used for classification purposes within a support vector machine scheme. Our results suggest that coupling complexity is able to capture essential characteristics, sufficient to distinguish among different violins.

    1992-01-01

    The German X-ray Ordinance (Roentgenverordnung) contains the main protective provisions applying to the field of X-ray equipment and sources of unwanted X radiation. It thus forms a complement to the German Radiation Protection Ordinance (Strahlenschutzverordnung). The X-ray Ordinance is based, as is the Radiation Protection Ordinance, on the German Nuclear Energy Act (Atomgesetz). It transposes the same Euratom Directives into national law, through which above all the limit values are defined. The current state of the X-ray Ordinance is that of the text promulgated on 8.01.1987 with the subsequent amendments, the last of which was adopted on 19.12.1990. The brochure also reproduces the Official Memorandum to the X-ray Ordinance, as this gives important indications for the legal construction of the Ordinance. (orig./HSCH) [de

    The purpose of this study was to investigate the preferences of elected city officials regarding the need for a statewide clean indoor air law and to analyze the content of local smoking ordinances. A survey of elected officials in 57 larger Kansas cities obtained information on the perceived need for statewide legislation, venues to be covered, and motivating factors. Clean indoor air ordinances from all Kansas cities were analyzed by venue. The survey response rate was 190 out of 377 (50.4%) for elected officials. Over 70% of the respondents favored or strongly favored greater restrictions on indoor smoking. Sixty percent favored statewide legislation. Among these, over 80% favored restrictions in health care facilities, theaters, indoor sports arenas (including bowling alleys), restaurants, shopping malls, lobbies, enclosed spaces in outdoor arenas, and hotel/motel rooms. Officials who had never smoked favored a more restrictive approach. Employee and public health concerns were cited as influential by 76%-79% of respondents. Thirty-eight ordinances, covering over half of the state's population, were examined. They varied considerably in their exemptions. Official's attitudes toward smoking regulations were associated with their smoking status. The examination of existing ordinances revealed a piecemeal approach to smoking regulations.

  15. Lanthanide co-ordination frameworks: Opportunities and diversity

    Hill, Robert J.; Long, De-Liang; Hubberstey, Peter; Schroeder, Martin; Champness, Neil R.

    2005-01-01

    Significant successes have been made over recent years in preparing co-ordination framework polymers that show macroscopic material properties, but in the vast majority of cases this has been achieved with d-block metal-based systems. Lanthanide co-ordination frameworks also offer attractive properties in terms of their potential applications as luminescent, non-linear optical and porous materials. However, lanthanide-based systems have been far less studied to date than their d-block counterparts. One possible reason for this is that the co-ordination spheres of lanthanide cations are more difficult to control and, in the absence of design strategies for lanthanide co-ordination frameworks, it is significantly more difficult to target materials with specific properties. However, this article highlights some of the exciting possibilities that have emerged from the earliest investigations in this field with new topological families of compounds being discovered from relatively simple framework components, including unusual eight, seven and five-connected framework systems. Our own research, as well as others, is leading to a much greater appreciation of the factors that control framework formation and the resultant observed topologies of these polymers. As this understanding develops targeting particular framework types will become more straightforward and the development of designed polyfunctional materials more accessible. Thus, it can be seen that lanthanide co-ordination frameworks have the potential to open up previously unexplored directions for materials chemistry. This article focuses on the underlying concepts for the construction of these enticing and potentially highly important materials

    In this paper we describe and demonstrate a discrete ordinates sweep algorithm on GPUs. This sweep algorithm is nested within a multilevel comunication-based decomposition based on energy. We demonstrated the effectiveness of this algorithm on detailed three-dimensional critical experiments and PWR lattice problems. For these problems we show improvement factors of 4 6 over conventional communication-based, CPU-only sweeps. These sweep kernel speedups resulted in a factor of 2 total time-to-solution improvement.

    A concise and accurate procedure for evaluating dose distribution, in a radiation therapy planning, is presented. The analytical discrete-ordinates method (ADO method) is used to develop a complete solution for a spectral dependent radiative transfer equation, in a one-dimensional medium, according to a multigroup scheme. Numerical results are presented for test problems, where the Klein-Nishina scattering kernel was used to describe the interaction processes. (author)

    With most Newly Independent States (NIS) of the former Soviet Union becoming parties to the Non-Proliferation Treaty as Non-Nuclear Weapon States, there has been an acute need in these states for considerable assistance for the establishment of the necessary structure and resources to ensure that their commitments to non-proliferation are fully implemented in a timely manner. A number of IAEA Member States have offered and are now providing assistance to the NIS on a bilateral level to set up an appropriate State System of Accounting and Control (SSAC) which includes Import/Export Control and Physical Protection of Nuclear Material in each state. The IAEA and these Member States established the Co-ordinated Technical Support Programme (CTSP) to ensure that the support given to the NIS was done in a co-ordinated and transparent manner and to avoid duplication of effort. The IAEA has played a coordinating role for the past 5 years by helping to identify detailed needs in individual States, by providing a platform for Member States to identify areas where they could provide the optimum support, and in developing and preparing the Co-ordinated Technical Support Plans. The IAEA organises annual meetings in Vienna attended by all donor and recipient countries to review the focus and implementation status of the co-ordinated technical support activities. A position statement is made by each donor and recipient country, and views and experiences are exchanged. The contents of the CTSPs and the role of the Agency in monitoring the progress of the individual tasks are reviewed in this paper. A summary comparing the implementation status of the Programme by each country is presented. (author)

  7. Classification of forested wetlands using ordination of multitemporal Landsat reflectance

    2007-12-01

    There are important limitations in interpreting satellite imagery in dynamic environments. In forested wetlands, where flooding and aquatic vegetation vary temporally, a multitemporal approach is needed for extracting stable patterns. We used field measurements of forest composition and structure and seven cloud-free Landsat images from a time span of six years to classify forest vigor in 95,000 ha of cypress-tupelo forested wetlands surrounding Lake Verret in southern Louisiana. A principal component (PCA) ordination of the reflectance in Landsat bands 3/4/5 for each image was the basis of the classification. No single Landsat band or image dominated the first few PCs, so that the multitemporal and multispectral aspect of the data were fully expressed in the ordination. Each Landsat pixel was classified as to forest vigor according to its scores in the first two PCs by comparing pixel scores to those associated with field plots. The reflectance PCA, and thus the classification, was directly interpretable in terms of ecosystem structure because the scored in the first two PCs in field-plot pixels were correlated to field measurements of forest structure, such as leaf area index, stand density, and understory composition, and because the field plots occupied interpretable regions of ordination space.

  8. Multidimensional electron-photon transport with standard discrete ordinates codes

    International Nuclear Information System (INIS)

    Drumm, C.R.

    1997-01-01

    A method is described for generating electron cross sections that are comparable with standard discrete ordinates codes without modification. There are many advantages of using an established discrete ordinates solver, e.g. immediately available adjoint capability. Coupled electron-photon transport capability is needed for many applications, including the modeling of the response of electronics components to space and man-made radiation environments. The cross sections have been successfully used in the DORT, TWODANT and TORT discrete ordinates codes. The cross sections are shown to provide accurate and efficient solutions to certain multidimensional electron-photon transport problems. The key to the method is a simultaneous solution of the continuous-slowing-down (CSD) portion and elastic-scattering portion of the scattering source by the Goudsmit-Saunderson theory. The resulting multigroup-Legendre cross sections are much smaller than the true scattering cross sections that they represent. Under certain conditions, the cross sections are guaranteed positive and converge with a low-order Legendre expansion

Si raggiunge questo obiettivo a partire dalla concezione del burnout come risultato di stress lavoro-correlato che si muove su dimensioni plurime, aventi carattere sia soggettivo che organizzativo.

    Several observations suggest that overlearned ordinal categories (e.g., letters, numbers, weekdays, months) are processed differently than non-ordinal categories in the brain. In synesthesia, for example, anomalous perceptual experiences are most often triggered by members of ordinal categories (Rich et al., 2005; Eagleman, 2009). In semantic dementia (SD), the processing of ordinal stimuli appears to be preserved relative to non-ordinal ones (Cappelletti et al., 2001). Moreover, ordinal stimuli often map onto unconscious spatial representations, as observed in the SNARC effect (Dehaene et al., 1993; Fias, 1996). At present, little is known about the neural representation of ordinal categories. Using functional neuroimaging, we show that words in ordinal categories are processed in a fronto-temporo-parietal network biased toward the right hemisphere. This differs from words in non-ordinal categories (such as names of furniture, animals, cars, and fruit), which show an expected bias toward the left hemisphere. Further, we find that increased predictability of stimulus order correlates with smaller regions of BOLD activation, a phenomenon we term prediction suppression. Our results provide new insights into the processing of ordinal stimuli, and suggest a new anatomical framework for understanding the patterns seen in synesthesia, unconscious spatial representation, and SD.

    1981-01-01

    There are laws, government and ministerial ordinances and notifications, each of them bears a definite role, and the contents of the legal regulation on a certain range of matter are determined by their close interrelation and mutual supplementation. Many laws and ordinances concerning atomic energy also form a legal system under such mutual relation. The Atomic Energy Act is positioned at its top, and the main part related to radiation injury prevention comprises a law, two ordinances, a regulation and a notification. Such relationship of individual laws and ordinances is mostly shown in lower rank laws and ordinances. In Chapter 1 of this book, the Atomic Energy Act and the government ordinance concerning the definition of nuclear fuel materials, nuclear raw materials, nuclear reactors and radiation are described. In Chapter 2, the law concerning prevention of radiation injuries due to radiactive isotopes and others, the ordinances and eight notifications closely related to them are collected. In Chapter 3, other related laws and ordinances are gathered. To understand the laws and ordinances synthetically and systematically, the provisions of different laws and ordinances, which are mutually related, are arranged together showing their relation.

    2008-11-01

    In order to plan accurate motor actions, the brain needs to build an integrated spatial representation associated with visual stimuli and haptic stimuli. Since visual stimuli are represented in retina-centered co-ordinates and haptic stimuli are represented in body-centered co-ordinates, co-ordinate transformations must occur between the retina-centered co-ordinates and body-centered co-ordinates. A spiking neural network (SNN) model, which is trained with spike-timing-dependent-plasticity (STDP), is proposed to perform a 2D co-ordinate transformation of the polar representation of an arm position to a Cartesian representation, to create a virtual image map of a haptic input. Through the visual pathway, a position signal corresponding to the haptic input is used to train the SNN with STDP synapses such that after learning the SNN can perform the co-ordinate transformation to generate a representation of the haptic input with the same co-ordinates as a visual image. The model can be applied to explain co-ordinate transformation in spiking neuron based systems. The principle can be used in artificial intelligent systems to process complex co-ordinate transformations represented by biological stimuli.

    Robbery-related homicides and assaults are the leading cause of death in retail businesses. Robbery reduction approaches focus on compliance to Crime Prevention Through Environmental Design (CPTED) guidelines. We evaluated the level of compliance to CPTED guidelines specified by convenience store safety ordinances effective in 2010 in Dallas and Houston, Texas, USA. Convenience stores were defined as businesses less than 10 000 square feet that sell grocery items. Store managers were interviewed for store ordinance requirements from August to November 2011, in a random sample of 594 (289 in Dallas, 305 in Houston) convenience stores that were open before and after the effective dates of their city's ordinance. Data were collected in 2011 and analysed in 2012-2014. Overall, 9% of stores were in full compliance, although 79% reported being registered with the police departments as compliant. Compliance was consistently significantly higher in Dallas than in Houston for many requirements and by store type. Compliance was lower among single owner-operator stores compared with corporate/franchise stores. Compliance to individual requirements was lowest for signage and visibility. Full compliance to the required safety measures is consistent with industry 'best practices' and evidence-based workplace violence prevention research findings. In Houston and Dallas compliance was higher for some CPTED requirements but not the less costly approaches that are also the more straightforward to adopt.

  18. I concetti di "materia", "forma" e "ordine" nel pensiero teorico musicale medievale e contemporaneo

    Directory of Open Access Journals (Sweden)

    Cecilia Panti

    2011-01-01

    Full Text Available La dimensione teorica della musica occidentale, nella sua evoluzione storica, ha inevitabilmente fatto uso di concetti essenziali alla definizione di come il suono è musicalmente organizzato o organizzabile. Fra questi, risultano imprescindibili le nozioni di materia, forma e ordine, che implicano rispettivamente, nei pur diversi ambiti linguistici e contesti storico-filosofici di riferimento, ciò di cui è fatta la musica, ciò a cui la materia sonora tende, e come tale tensione è realizzata. Scopo di questo contributo è una valutazione d’insieme sulla valenza filosofica e l’uso di tali concetti nel pensiero musicale occidentale altomedievale e in quello del Novecento, che nonostante la distanza cronologica presentano convergenze significative. Nel Medioevo, un lungo processo di elaborazione teorico-pratica permise la matematizzazione dello spazio (e, più tardi, anche del tempo musicale, attraverso l’adattamento di moduli melodici, trasmessi oralmente, alle strutture scalari desunte dalla teoria greco-boeziana. La forma e l’ordo musicali furono quindi riferiti ai criteri fisico-matematici atti a distinguere nella materia sonora, in sé disorganica e indefinita, ciò che è musicale da ciò che non lo è. Tale concezione sparisce con l’affermarsi del sistema tonale, ove il suono fisico è concepito come “pre-formato” e “pre-ordinato” nella gamma scalare e nei vincoli attrattivi “naturali” degli armonici. In conseguenza, i concetti di forma e ordine abbandonano il contesto acustico, andando a definire i criteri teorici della composizione artistica, in linea con l’idea filosofica del loro esprimere la coerenza logico-sintattica dell’“insieme organico” (la Formenlehre teorizzata da Widmann. Nell’ambito del pensiero musicale del Novecento, la crisi del sistema tonale e la messa a punto di nuove modalità e tecniche di produzione del suono hanno riorientato la valenza significante e l’uso di questi tre concetti

    1984-01-01

    The diffusion-synthetic acceleration (DSA) method is an iterative procedure for obtaining numerical solutions of discrete-ordinates problems. The DSA method is operationally more complicated than the standard source-iteration (SI) method, but if encoded properly it converges much more rapidly, especially for problems with diffusion-like regions. In this article we describe the basic ideas behind the DSA method and give a (roughly chronological) review of its long development. We conclude with a discussion which covers additional topics, including some remaining open problems an the status of current efforts aimed at solving these problems

  3. Matrix albedo for discrete ordinates infinite-medium boundary condition

    International Nuclear Information System (INIS)

    Mathews, K.; Dishaw, J.

    2007-01-01

    Discrete ordinates problems with an infinite exterior medium (reflector) can be more efficiently computed by eliminating grid cells in the exterior medium and applying a matrix albedo boundary condition. The albedo matrix is a discretized bidirectional reflection distribution function (BRDF) that accounts for the angular quadrature set, spatial quadrature method, and spatial grid that would have been used to model a portion of the exterior medium. The method is exact in slab geometry, and could be used as an approximation in multiple dimensions or curvilinear coordinates. We present an adequate method for computing albedo matrices and demonstrate their use in verifying a discrete ordinates code in slab geometry by comparison with Ganapol's infinite medium semi-analytic TIEL benchmark. With sufficient resolution in the spatial and angular grids and iteration tolerance to yield solutions converged to 6 digits, the conventional (scalar) albedo boundary condition yielded 2-digit accuracy at the boundary, but the matrix albedo solution reproduced the benchmark scalar flux at the boundary to all 6 digits.

Più passa il tempo più le visioni pessimiste acquistano motivazioni e argomenti validi. Per trasformare radicalmente in pochi decenni un sistema energetico e un rapporto predatorio verso le risorse del pianeta è necessario riconoscere la crisi climatica nella sua dimensione sistemica, nel suo essere prima di tutto un problema di giustizia, di equità anche verso le generazioni future. La scienza del clima dovrebbe aiutare a capire la portata della sfida chiarendo meglio le conseguenze delle scelte odierne per le generazioni future. Ma uno sforzo molto più grande è quello di recuperare le ragioni per occuparci, come individui e comunità, dei nostri posteri. Capire la posta in gioco sul tema del cambiamento climatico richiede non solo più conoscenza, ma di accettare l’esistenza dei limiti planetari, di ridefinire le aspettative amane, nonché un livello di intelligenza emotiva oggi insufficiente.

    Although various discrete-ordinates quadrature sets are in general use, there exists a need for a standard collection supported by documentation of their origin and derivation. This report attempts to provide this documentation for most of the commonly used sets. Instructions for using DOQDP--the computer code used to generate these quadratures--is provided. A library (in standard interface format) containing many of the quadratures was generated and is documented in this report. Finally, a listing of the fully symmetric, half-symmetric, and several biased sets is provided for XY, RZ, and R THETA geometries. Part I of the report describes the DOQDP code and the generation of S2-S16 fully symmetric quadratures. Part II describes the generation of S4-S10 half-symmetric and several biased sets, as well as a discussion of the quadrature library. 2 figures, 1 table

    A discrete ordinate response matrix method is formulated for the solution of neutron transport problems on massively parallel computers. The response matrix formulation eliminates iteration on the scattering source. The nodal matrices which result from the diamond-differenced equations are utilized in a factored form which minimizes memory requirements and significantly reduces the required number of algorithm utilizes massive parallelism by assigning each spatial node to a processor. The algorithm is accelerated effectively by a synthetic method in which the low-order diffusion equations are also solved by massively parallel red/black iterations. The method has been implemented on a 16k Connection Machine-2, and S 8 and S 16 solutions have been obtained for fixed-source benchmark problems in X--Y geometry

    Qin, Yi; Box, Michael A; Jupp, David L

    2004-06-20

    We present two methods that can be used to derive the particular solution of the discrete-ordinate method (DOM) for an arbitrary source in a plane-parallel atmosphere, which allows us to solve the transfer equation 12-18% faster in the case of a single beam source and is even faster for the atmosphere thermal emission source. We also remove the divide by zero problem that occurs when a beam source coincides with a Gaussian quadrature point. In our implementation, solution for multiple sources can be obtained simultaneously. For each extra source, it costs only 1.3-3.6% CPU time required for a full solution. The GDOM code that we developed previously has been revised to integrate with the DOM. Therefore we are now able to compute the Green's function and DOM solutions simultaneously.

  8. Parallel ray tracing for one-dimensional discrete ordinate computations

    Jarvis, R.D.; Nelson, P.

    1996-01-01

    The ray-tracing sweep in discrete-ordinates, spatially discrete numerical approximation methods applied to the linear, steady-state, plane-parallel, mono-energetic, azimuthally symmetric, neutral-particle transport equation can be reduced to a parallel prefix computation. In so doing, the often severe penalty in convergence rate of the source iteration, suffered by most current parallel algorithms using spatial domain decomposition, can be avoided while attaining parallelism in the spatial domain to whatever extent desired. In addition, the reduction implies parallel algorithm complexity limits for the ray-tracing sweep. The reduction applies to all closed, linear, one-cell functional (CLOF) spatial approximation methods, which encompasses most in current popular use. Scalability test results of an implementation of the algorithm on a 64-node nCube-2S hypercube-connected, message-passing, multi-computer are described. (author)

  9. Comparing interval estimates for small sample ordinal CFA models.

    Natesan, Prathiba

    2015-01-01

    Robust maximum likelihood (RML) and asymptotically generalized least squares (AGLS) methods have been recommended for fitting ordinal structural equation models. Studies show that some of these methods underestimate standard errors. However, these studies have not investigated the coverage and bias of interval estimates. An estimate with a reasonable standard error could still be severely biased. This can only be known by systematically investigating the interval estimates. The present study compares Bayesian, RML, and AGLS interval estimates of factor correlations in ordinal confirmatory factor analysis models (CFA) for small sample data. Six sample sizes, 3 factor correlations, and 2 factor score distributions (multivariate normal and multivariate mildly skewed) were studied. Two Bayesian prior specifications, informative and relatively less informative were studied. Undercoverage of confidence intervals and underestimation of standard errors was common in non-Bayesian methods. Underestimated standard errors may lead to inflated Type-I error rates. Non-Bayesian intervals were more positive biased than negatively biased, that is, most intervals that did not contain the true value were greater than the true value. Some non-Bayesian methods had non-converging and inadmissible solutions for small samples and non-normal data. Bayesian empirical standard error estimates for informative and relatively less informative priors were closer to the average standard errors of the estimates. The coverage of Bayesian credibility intervals was closer to what was expected with overcoverage in a few cases. Although some Bayesian credibility intervals were wider, they reflected the nature of statistical uncertainty that comes with the data (e.g., small sample). Bayesian point estimates were also more accurate than non-Bayesian estimates. The results illustrate the importance of analyzing coverage and bias of interval estimates, and how ignoring interval estimates can be misleading

  10. The adaptive collision source method for discrete ordinates radiation transport

    International Nuclear Information System (INIS)

    Walters, William J.; Haghighat, Alireza

    2017-01-01

    Highlights: • A new adaptive quadrature method to solve the discrete ordinates transport equation. • The adaptive collision source (ACS) method splits the flux into n’th collided components. • Uncollided flux requires high quadrature; this is lowered with number of collisions. • ACS automatically applies appropriate quadrature order each collided component. • The adaptive quadrature is 1.5–4 times more efficient than uniform quadrature. - Abstract: A novel collision source method has been developed to solve the Linear Boltzmann Equation (LBE) more efficiently by adaptation of the angular quadrature order. The angular adaptation method is unique in that the flux from each scattering source iteration is obtained, with potentially a different quadrature order used for each. Traditionally, the flux from every iteration is combined, with the same quadrature applied to the combined flux. Since the scattering process tends to distribute the radiation more evenly over angles (i.e., make it more isotropic), the quadrature requirements generally decrease with each iteration. This method allows for an optimal use of processing power, by using a high order quadrature for the first iterations that need it, before shifting to lower order quadratures for the remaining iterations. This is essentially an extension of the first collision source method, and is referred to as the adaptive collision source (ACS) method. The ACS methodology has been implemented in the 3-D, parallel, multigroup discrete ordinates code TITAN. This code was tested on a several simple and complex fixed-source problems. The ACS implementation in TITAN has shown a reduction in computation time by a factor of 1.5–4 on the fixed-source test problems, for the same desired level of accuracy, as compared to the standard TITAN code.

  11. An approach to solve group-decision-making problems with ordinal interval numbers.

    The ordinal interval number is a form of uncertain preference information in group decision making (GDM), while it is seldom discussed in the existing research. This paper investigates how the ranking order of alternatives is determined based on preference information of ordinal interval numbers in GDM problems. When ranking a large quantity of ordinal interval numbers, the efficiency and accuracy of the ranking process are critical. A new approach is proposed to rank alternatives using ordinal interval numbers when every ranking ordinal in an ordinal interval number is thought to be uniformly and independently distributed in its interval. First, we give the definition of possibility degree on comparing two ordinal interval numbers and the related theory analysis. Then, to rank alternatives, by comparing multiple ordinal interval numbers, a collective expectation possibility degree matrix on pairwise comparisons of alternatives is built, and an optimization model based on this matrix is constructed. Furthermore, an algorithm is also presented to rank alternatives by solving the model. Finally, two examples are used to illustrate the use of the proposed approach.

    The harmful effects of secondhand smoke are convincing more and more communities across the United States and the world to prohibit smoking in public places, especially in eating and drinking establishments. A 1993 Missouri state law allows smoking in designated areas in indoor public places such as restaurants and bars. Consequently, some Missouri communities have adopted local ordinances that prohibit smoking in all indoor workplaces, including restaurants and bars. We used an objective measure of economic activity, the taxable sales revenues of eating and drinking establishments, to empirically examine the economic effect of smoke-free ordinances. We studied the economic effect of smoke-free ordinances in 11 Missouri cities using multivariate log-linear regression models with log-transformed taxable sales revenues of eating and drinking establishments as the dependent variable and the smoke-free ordinance as the independent variable, while controlling for seasonality, economic condition and unemployment. We used data from 20 quarters before the smoke-free ordinances and at least 10 quarters after the smoke-free ordinances for all cities. The null hypothesis of no effect of smoke-free ordinance on taxable sales of the eating and drinking establishments was tested. Eight of the 11 cities had increased taxable sales for eating and drinking establishments postordinance. The remaining 3 experienced no change. The findings of our study are consistent with findings from most published economic studies that a smoke-free ordinance does not harm a local economy.

  20. No toy for you! The healthy food incentives ordinance: paternalism or consumer protection?

    Etow, Alexis M

    2012-01-01

    The newest approach to discouraging children's unhealthy eating habits, amidst increasing rates of childhood obesity and other diet-related diseases, seeks to ban something that is not even edible. In 2010, San Francisco enacted the Healthy Food Incentives Ordinance, which prohibits toys in kids' meals if the meals do not meet certain nutritional requirements. Notwithstanding the Ordinance's impact on interstate commerce or potential infringement on companies' commercial speech rights and on parents' rights to determine what their children eat, this Comment argues that the Ordinance does not violate the dormant Commerce Clause, the First Amendment, or substantive due process. The irony is that although the Ordinance likely avoids the constitutional hurdles that hindered earlier measures aimed at childhood obesity, it intrudes on civil liberties more than its predecessors. This Comment analyzes the legality of the Healthy Food Incentives Ordinance to understand its implications on subsequent legislation aimed at combating childhood obesity and on the progression of public health law.

Ma è soprattutto nella critica letteraria che Benjamin espone le sue più brillanti intuizioni: dallo sprigionarsi delle forze primordiali della natura che, nelle Affinità elettive di Goethe, tra violenza del diritto e libertà etica, si impossessano dei personaggi, alla dialettica del “risveglio” con Proust e i surrealisti, e all’esperienza profonda della vie antérieur di Baudelaire. Così, senza mai distanziarsi dal radicamento della condizione storica del suo tempo e senza mai cadere in facile misticismo, Walter Benjamin ha acutamente ispezionato le tracce del mito nella modernità, auspicando con intelligenza la liberazione umana dalla schiavitù della barbarie contingenti.

    1992-01-01

    The German Radiation Protection Ordinance constitutes the central statutory instrument containing the main protective provisions for all fields of application of radioactive materials and ionizing radiation, with the exception of the field covered by the X-ray Ordinance. The current text of the Ordinance is that promulgated on 30.06.1989 with the subsequent amendments, as last amended through the Unification Treaty (Einigungsvertrag) of 23.09.1990. The Radiation Protection Ordinance was adopted on the basis of the German Nuclear Energy Act (Atomgesetz), which contains, inter alia, the necessary empowerments to issue statutory ordinances. Further fields containing relevant protective provisions are, above all, the law of dangerous substances (which concerns the transport of radioactive materials), the law of pharmaceutical products and the law of foodstuffs. The whole regulatory package is a part of EC and Euratom law. The limit values of the Euratom Directives were transposed into the Radiation Protection Ordinance. In order to reduce the bulk of the Ordinance, the legislator has only included the limit values for the most important radionuclides, and has made provision for the separate promulgation of the other limit values. In order to enhance the practical use of the book, the provisions governing the radiation pass, which are regulated in a separate administrative instruction, are also reproduced. (orig./HSCH) [de

  9. Time-varying effect models for ordinal responses with applications in substance abuse research.

    Ordinal responses are very common in longitudinal data collected from substance abuse research or other behavioral research. This study develops a new statistical model with free SAS macros that can be applied to characterize time-varying effects on ordinal responses. Our simulation study shows that the ordinal-scale time-varying effects model has very low estimation bias and sometimes offers considerably better performance when fitting data with ordinal responses than a model that treats the response as continuous. Contrary to a common assumption that an ordinal scale with several levels can be treated as continuous, our results indicate that it is not so much the number of levels on the ordinal scale but rather the skewness of the distribution that makes a difference on relative performance of linear versus ordinal models. We use longitudinal data from a well-known study on youth at high risk for substance abuse as a motivating example to demonstrate that the proposed model can characterize the time-varying effect of negative peer influences on alcohol use in a way that is more consistent with the developmental theory and existing literature, in comparison with the linear time-varying effect model.

    In the Netherlands, youth-care organisations and community sports clubs are collaborating to increase socially vulnerable youths' participation in sport. This is rooted in the idea that sports clubs are settings for youth development. As not much is known about co-ordinated action involving professional care organisations and community sports clubs, this study aims to generate insight into facilitators of and barriers to successful co-ordinated action between these two organisations. A cross-sectional study was conducted using in-depth semi-structured qualitative interview data. In total, 23 interviews were held at five locations where co-ordinated action between youth-care and sports takes place. Interviewees were youth-care workers, representatives from community sports clubs, and Care Sport Connectors who were assigned to encourage and manage the co-ordinated action. Using inductive coding procedures, this study shows that existing and good relationships, a boundary spanner, care workers' attitudes, knowledge and competences of the participants, organisational policies and ambitions, and some elements external to the co-ordinated action were reported to be facilitators or barriers. In addition, the participants reported that the different facilitators and barriers influenced the success of the co-ordinated action at different stages of the co-ordinated action. Future research is recommended to further explore the role of boundary spanners in co-ordinated action involving social care organisations and community sports clubs, and to identify what external elements (e.g. events, processes, national policies) are turning points in the formation, implementation and continuation of such co-ordinated action. © 2017 John Wiley & Sons Ltd.

  11. ASOP, Shield Calculation, 1-D, Discrete Ordinates Transport

    International Nuclear Information System (INIS)

    1993-01-01

    1 - Nature of physical problem solved: ASOP is a shield optimization calculational system based on the one-dimensional discrete ordinates transport program ANISN. It has been used to design optimum shields for space applications of SNAP zirconium-hydride-uranium- fueled reactors and uranium-oxide fueled thermionic reactors and to design beam stops for the ORELA facility. 2 - Method of solution: ASOP generates coefficients of linear equations describing the logarithm of the dose and dose-weight derivatives as functions of position from data obtained in an automated sequence of ANISN calculations. With the dose constrained to a design value and all dose-weight derivatives required to be equal, the linear equations may be solved for a new set of shield dimensions. Since changes in the shield dimensions may cause the linear functions to change, the entire procedure is repeated until convergence is obtained. The detailed calculations of the radiation transport through shield configurations for every step in the procedure distinguish ASOP from other shield optimization computer code systems which rely on multiple component sources and attenuation coefficients to describe the transport. 3 - Restrictions on the complexity of the problem: Problem size is limited only by machine size

  12. Discrete ordinates quadrature schemes for multidimensional radiative transfer

    1995-04-01

    The fundamental problem of applying the method of discrete ordinates to radiative transfer predictions is the selection of the discrete directions and their associated weights. Both the accuracy of the solution and the computational effort depend on the angular discretization. This paper provides a sound mathematical methodology for the derivation of angular quadratures. By applying the collocation principle, the errors introduced by a quadrature are analyzed and the constituting equations of angular quadratures are identified. Special emphasis is placed on the rotational invariance of the qudrature schemes. Multidimensional radiative transfer in participating media with isotropic and anisotropic scattering is accounted for thoughout the analysis. A major goal of the present study is the construction of a new principle for multidimensional angular quadratures which is essentially a generalization of the principles employed for the well-known S(sub n) quadratures. The new construction principle has two major advantages. First, it enables a very flexible tailoring of quadratures according to the actual requirements. Second, compared to the S(sub n) quadratures, the new types of quadratures provide a higher accuracy while using the same number of nodal points.

    The case study was based on the osteologic collection of the chair for anthropology, State Moscow University, including the male carpal bones (67) and female carpal bones (13), aged above 18 to 20. Four measurements were made according to Martin's scheme for metacarpal bones and finger phalanxes. A diagnostic method was worked out on the bases of the discriminative analysis, with such method enabling the remodeling of the ordinal localization of metacarpal bones as well as of main, medium and distal phalanxes. The maximally accurate classification was ensured for metacarpal bones, ranging from 81.5% to 100%; and the minimally accurate one was achieved for distal phalanxes, ranging from 20% to 95%. The discriminative analysis results were checked for distal phalanxes by Neklyudov's series (male--100, female--85); they were described according to 7 sizes. However, an attempt to enhance the accuracy of the classification of these phalanxes failed. The offered method should be applied in combination with the traditional anatomic-and-morphological method; besides, if possible, it is necessary to check the congruence of joint surfaces in the metacarpal interphalangeal joints.

    2009-01-01

    Although the transport of photons and electrons/positrons can be described by the same Boltzmann transport equation, the cross sections are very different, resulting in very different iterative convergence properties for the two particle types. The SCEPTRE project contains a suite of deterministic codes for solving the linear steady-state Boltzmann transport equation, including two very different solution algorithms: a sweeps-based approach for solving the first-order transport equation that is efficient for photon transport, and a conjugate-gradient algorithm for solving the second-order transport equation that is efficient for electron/positron transport. These two solution algorithms are coupled through a common set of interfaces to handle the finite element approximation in space, the discrete-ordinates method in angle, the scattering source terms, input parsing, pre- and post-processing capabilities. We evaluate the two solution algorithms by comparing the run times for photon- and electron-transport problems, investigating parallel performance and effects from finite-element basis function types, preconditioning, and scaling with angular quadrature order and Legendre cross section expansion order.

    1995-12-31

    It was with the realisation that the scientific problems associated with regional air pollution could only be solved within the framework of an international interdisciplinary approach that in 1985 EUROTRAC, the European co-ordinated research project, was formed. Such an approach provides the scientific consensus necessary for the acceptance of regional air-pollution abatement measures by the countries affected. EUROTRAC is a EUREKA environmental project, studying the transport and chemical transformation of trace substances and pollutants in the troposphere. Three goals were specified the outset: (1) to increase the basic knowledge in atmospheric science, (2) to promote the technological development of sensitive, specific and fast response instruments for environmental research and development, and (3) to improve the scientific basis for taking future political decisions on environmental management in the European countries. Thus EUROTRAC was founded as a scientific project but had the specific intention that its results should be utilised in the formulation of policy. This presentation reviews the progress made towards each of the three goals and also indicates the proposed direction which a follow-on project is likely to take when EUROTRAC finishes at the end of 1995.

  16. Prediction of spectral acceleration response ordinates based on PGA attenuation

    2009-01-01

    Developed herein is a new peak ground acceleration (PGA)-based predictive model for 5% damped pseudospectral acceleration (SA) ordinates of free-field horizontal component of ground motion from shallow-crustal earthquakes. The predictive model of ground motion spectral shape (i.e., normalized spectrum) is generated as a continuous function of few parameters. The proposed model eliminates the classical exhausted matrix of estimator coefficients, and provides significant ease in its implementation. It is structured on the Next Generation Attenuation (NGA) database with a number of additions from recent Californian events including 2003 San Simeon and 2004 Parkfield earthquakes. A unique feature of the model is its new functional form explicitly integrating PGA as a scaling factor. The spectral shape model is parameterized within an approximation function using moment magnitude, closest distance to the fault (fault distance) and VS30 (average shear-wave velocity in the upper 30 m) as independent variables. Mean values of its estimator coefficients were computed by fitting an approximation function to spectral shape of each record using robust nonlinear optimization. Proposed spectral shape model is independent of the PGA attenuation, allowing utilization of various PGA attenuation relations to estimate the response spectrum of earthquake recordings.

    2005-06-01

    Hepatocellular carcinoma is a very common neoplastic disease in countries where hepatitis viruses B and/or C are prevalent. Small hepatocellular carcinoma lesions detected by ultrasonography at an early stage are often hyperechoic because they are composed of well-differentiated cancer cells that are rich in triglyceride droplets. The triglyceride content of hepatocytes depends in part on the rate of lipogenesis. Key lipogenic enzymes, such as fatty acid synthase, are co-ordinately regulated at the transcriptional level. We therefore examined the mRNA expression of lipogenic enzymes in human hepatocellular carcinoma samples from 10 patients who had undergone surgical resection. All of the samples exhibited marked elevation of expression of mRNA for lipogenic enzymes, such as fatty acid synthase, acetyl-CoA carboxylase and ATP citrate lyase, compared with surrounding non-cancerous liver tissue. In contrast, the changes in mRNA expression of SREBP-1, a transcription factor that regulates a battery of lipogenic enzymes, did not show a consistent trend. In some cases where SREBP-1 was elevated, the main contributing isoform was SREBP-1c rather than SREBP-1a. Thus, lipogenic enzymes are markedly induced in hepatocellular carcinomas, and in some cases SREBP-1c is involved in this activation.

  18. How protein kinases co-ordinate mitosis in animal cells.

    Ma, Hoi Tang; Poon, Randy Y C

    2011-04-01

    Mitosis is associated with profound changes in cell physiology and a spectacular surge in protein phosphorylation. To accomplish these, a remarkably large portion of the kinome is involved in the process. In the present review, we will focus on classic mitotic kinases, such as cyclin-dependent kinases, Polo-like kinases and Aurora kinases, as well as more recently characterized players such as NIMA (never in mitosis in Aspergillus nidulans)-related kinases, Greatwall and Haspin. Together, these kinases co-ordinate the proper timing and fidelity of processes including centrosomal functions, spindle assembly and microtubule-kinetochore attachment, as well as sister chromatid separation and cytokinesis. A recurrent theme of the mitotic kinase network is the prevalence of elaborated feedback loops that ensure bistable conditions. Sequential phosphorylation and priming phosphorylation on substrates are also frequently employed. Another important concept is the role of scaffolds, such as centrosomes for protein kinases during mitosis. Elucidating the entire repertoire of mitotic kinases, their functions, regulation and interactions is critical for our understanding of normal cell growth and in diseases such as cancers.

    With the remarkably increasing interest directed to the security dimension, the iris recognition process is considered to stand as one of the most versatile technique critically useful for the biometric identification and authentication process. This is mainly due to every individual's unique iris texture. A modestly conceived efficient approach relevant to the feature extraction process is proposed. In the first place, iris zigzag "collarette" is extracted from the rest of the image by means of the circular Hough transform, as it includes the most significant regions lying in the iris texture. In the second place, the linear Hough transform is used for the eyelids' detection purpose while the median filter is applied for the eyelashes' removal. Then, a special technique combining the richness of Gabor features and the compactness of ordinal measures is implemented for the feature extraction process, so that a discriminative feature representation for every individual can be achieved. Subsequently, the modified Hamming distance is used for the matching process. Indeed, the advanced procedure turns out to be reliable, as compared to some of the state-of-the-art approaches, with a recognition rate of 99.98%, 98.12%, and 95.02% on CASIAV1.0, CASIAV3.0, and IIT Delhi V1 iris databases, respectively.

    Children with developmental co-ordination disorder (DCD) experience significant difficulty in the performance of everyday movement skills in the absence of obvious neurological, sensory or intellectual impairment. They often underachieve academically and have higher rates of anxiety than their typically developing peers. Such factors are known to be associated with sleep problems in other clinical populations but the sleep patterns of children with DCD have not been examined. Information about the frequency and nature of sleep problems in DCD will aid our understanding of this developmental disorder. It may also be clinically helpful, alerting clinicians to potential difficulties so that these can be identified early and appropriate support offered. To examine sleep behaviour of children with DCD compared with typically developing control children. Two groups of 16 boys aged 8 to 12 years (M = 10.28, SD = 1.28) participated: (1) the DCD group had Movement ABC-2 Checklist scores below the 5th percentile; (2) an age-matched control group of typically developing children had Movement ABC-2 Checklist scores above the 15th percentile. Parents of children from both groups completed the Children's Sleep Habits Questionnaire. The total sleep disturbance score was significantly higher for children with DCD compared with the control group (U= 24, P sleep onset delay, sleep duration, night wakings and sleep-disordered breathing. These preliminary results suggest that sleep patterns of children with DCD may be of clinical relevance and are worthy of further investigation. © 2011 Blackwell Publishing Ltd.

  1. Human Action Recognition Using Ordinal Measure of Accumulated Motion

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available This paper presents a method for recognizing human actions from a single query action video. We propose an action recognition scheme based on the ordinal measure of accumulated motion, which is robust to variations of appearances. To this end, we first define the accumulated motion image (AMI using image differences. Then the AMI of the query action video is resized to a subimage by intensity averaging and a rank matrix is generated by ordering the sample values in the sub-image. By computing the distances from the rank matrix of the query action video to the rank matrices of all local windows in the target video, local windows close to the query action are detected as candidates. To find the best match among the candidates, their energy histograms, which are obtained by projecting AMI values in horizontal and vertical directions, respectively, are compared with those of the query action video. The proposed method does not require any preprocessing task such as learning and segmentation. To justify the efficiency and robustness of our approach, the experiments are conducted on various datasets.

We can justifiably apply multilevel cumulative logit model, where the outcome variable represents the mild, severe, and extremely severe intensity of diseases like malaria and typhoid in the form of ordered categories.

PQL method, however, performs equally well as ML method where five-category ordinal outcome variable is used. Further, to achieve power more than 0.80, at least 50 groups are required for both ML and PQL methods of estimation. It may be pointed out that, for five-category ordinal response variable model, the power of PQL method is slightly higher than the power of ML method.

  7. Spatial Treatment of the Slab-geometry Discrete Ordinates Equations Using Artificial Neural Networks

    International Nuclear Information System (INIS)

    Brantley, P S

    2001-01-01

    An artificial neural network (ANN) method is developed for treating the spatial variable of the one-group slab-geometry discrete ordinates (S N ) equations in a homogeneous medium with linearly anisotropic scattering. This ANN method takes advantage of the function approximation capability of multilayer ANNs. The discrete ordinates angular flux is approximated by a multilayer ANN with a single input representing the spatial variable x and N outputs representing the angular flux in each of the discrete ordinates angular directions. A global objective function is formulated which measures how accurately the output of the ANN approximates the solution of the discrete ordinates equations and boundary conditions at specified spatial points. Minimization of this objective function determines the appropriate values for the parameters of the ANN. Numerical results are presented demonstrating the accuracy of the method for both fixed source and incident angular flux problems

  8. Time dependence linear transport III convergence of the discrete ordinate method

    1983-01-01

    In this paper the uniform pointwise convergence of the discrete ordinate method for weak and strong solutions of the time dependent, linear transport equation posed in a multidimensional, rectangular parallelepiped with partially reflecting walls is established. The first result is that a sequence of discrete ordinate solutions converges uniformly on the quadrature points to a solution of the continuous problem provided that the corresponding sequence of truncation errors for the solution of the continuous problem converges to zero in the same manner. The second result is that continuity of the solution with respect to the velocity variables guarantees that the truncation erros in the quadrature formula go the zero and hence that the discrete ordinate approximations converge to the solution of the continuous problem as the discrete ordinate become dense. An existence theory for strong solutions of the the continuous problem follows as a result

    The aims of this study is to detect the outliers by using coefficients of Ordinal Logistic Regression (OLR) for the case of k category responses where the score from 1 (the best) to 8 (the worst). We detect them by using the sum of moduli of the ordinal regression coefficients calculated by jackknife technique. This technique is improved by scalling the regression coefficients to their means. R language has been used on a set of ordinal data from reference distribution. Furthermore, we compare this approach by using studentised residual plots of jackknife technique for ANOVA (Analysis of Variance) and OLR. This study shows that the jackknifing technique along with the proper scaling may lead us to reveal outliers in ordinal regression reasonably well.

    1997-01-01

    The method of discrete ordinates is applied to the solution of the slab albedo problem with azimuthal dependence in transport theory. A new set of quadratures appropriate to the problem is introduced. In addition to the ANISN code, modified to include the proposed formalism, two new programs, PEESNC and PEESNA, which were created on the basis of the discrete ordinates formalism, using the direct integration method and the analytic solution method respectively, are used in the generation of results for a few sample problems. Program PEESNC was created to validate the results obtained with the discrete ordinates method and the finite difference approximation (ANISN), while program PEESNA was developed in order to implement an analytical discrete ordinates formalism, which provides more accurate results. The obtained results for selected sample problems are compared with highly accurate numerical results published in the literature. Compared to ANISN and PEESNC, program PEESNA presents a greater efficiency in execution time and much more precise numerical results. (author)

    Full Text Available Abitare è rimanere in un luogo. È interagire con lo spazio, il paesaggio, la natura e gli uomini. Il risultato di quest’azione permane come un segno nel territorio ed è trasmessa alle generazioni future col passare del tempo. In questo modo a si afferma il concetto di patrimonio associato all’azione dell’abitare un luogo sia questo una casa, sia un convento, una città, un paesaggio costruito, etc. I luoghi del patrimonio sono il supporto fisico della memoria sociale, la quale è trasmessa nell’atto stesso del vivere umano. Così la memoria degli uomini è radicata nel modo in cui loro abitano i luoghi. Togliere ai luoghi questa caratteristica di vita, questa funzione dell’abitare, riduce drasticamente il senso del patrimonio ed il suo ruolo di monumento, di memoria vivente. Cercare di mantenere vivo il patrimonio, nelle sue diverse valenze, è il compito principale della società odierna rispetto al patrimonio costruito. Si può affermare che oggi conosciamo tutte le soluzioni tecniche per la conservazione dei monumenti. Non disponiamo tuttavia delle soluzioni sociali capaci di mantenerli viventi e attuanti nel nostro mondo contemporaneo. Il caso del Convento di Cristo diventa un paradigma di questa lotta per una nuova strategia di conservazione centrata sul vivere i luoghi, sull’abitare il patrimonio.

    1985-01-01

    Advantages and disadvantages of modern discrete-ordinates finite-element methods for the solution of radiative transfer problems in meteorology, climatology, and remote sensing applications are evaluated. After the common basis of the formulation of radiative transfer problems in the fields of neutron transport and atmospheric optics is established, the essential features of the discrete-ordinates finite-element method are described including the limitations of the method and their remedies. Numerical results are presented for 1-D and 2-D atmospheric radiative transfer problems where integral as well as angular dependent quantities are compared with published results from other calculations and with measured data. These comparisons provide a verification of the discrete-ordinates results for a wide spectrum of cases with varying degrees of absorption, scattering, and anisotropic phase functions. Accuracy and computational speed are also discussed. Since practically all discrete-ordinates codes offer a builtin adjoint capability, the general concept of the adjoint method is described and illustrated by sample problems. Our general conclusion is that the strengths of the discrete-ordinates finite-element method outweight its weaknesses. We demonstrate that existing general-purpose discrete-ordinates codes can provide a powerful tool to analyze radiative transfer problems through the atmosphere, especially when 2-D geometries must be considered

    The third sector has played a significant role internationally in the delivery of adult social care services for many years. Its contribution to care co-ordination activities for older people, however, in England and elsewhere, is relatively unknown. A scoping review was therefore conducted to ascertain the character of the literature, the nature and extent of third sector care co-ordination activity, and to identify evidence gaps. It was undertaken between autumn 2013 and summer 2014 and updated with additional searches in 2016. Electronic and manual searches of international literature using distinct terms for different approaches to care co-ordination were undertaken. From a total of 835 papers, 26 met inclusion criteria. Data were organised in relation to care co-ordination approaches, types of third sector organisation and care recipients. Papers were predominantly from the UK and published this century. Key findings included that: a minority of literature focused specifically on older people and that those doing so described only one care co-ordination approach; third sector services tended to be associated with independence and person-centred practice; and working with the statutory sector, a prerequisite of care co-ordination, was challenging and required a range of features to be in place to support effective partnerships. Strengths and weaknesses of care co-ordination practice in the third sector according to key stakeholder groups were also highlighted. Areas for future research included the need for: a specific focus on older people's experiences; an investigation of workforce issues; detailed examination of third sector practices, outcomes and costs; interactions with the statutory sector; and an examination of quality assurance systems and their appropriateness to third sector practice. The main implication of the findings is a need to nurture variety within the third sector in order to provide older people and other adults with the range of service

  20. Spatial coding of ordinal information in short- and long-term memory

    2015-01-01

    The processing of numerical information induces a spatial response bias: Faster responses to small numbers with the left hand and faster responses to large numbers with the right hand. Most theories agree that long-term representations underlie this so called SNARC effect (Spatial Numerical Association of Response Codes; Dehaene et al., 1993). However, a spatial response bias was also observed with the activation of temporary position-space associations in working memory (ordinal position effect; van Dijck and Fias, 2011). Items belonging to the beginning of a memorized sequence are responded to faster with the left hand side while items at the end of the sequence are responded to faster with the right hand side. The theoretical possibility was put forward that the SNARC effect is an instance of the ordinal position effect, with the empirical consequence that the SNARC effect and the ordinal position effect cannot be observed simultaneously. In two experiments we falsify this claim by demonstrating that the SNARC effect and the ordinal position effect are not mutually exclusive. Consequently, this suggests that the SNARC effect and the ordinal position effect result from the activation of different representations. We conclude that spatial response biases can result from the activation of both pre-existing positions in long-term memory and from temporary space associations in working memory at the same time.

    Full Text Available In the United States, smoking is the leading cause of death - having a mortality rate of approximately 435,000 people in 2000—accounting for 8.1% of all US deaths recorded that year. Consequently, we analyzed the Delaware Hospital Discharge Database, and identified state and non-state residents discharged with AMI or asthma for the years 1999 to 2004. Statistical data analysis compared the incidence of AMI or asthma for each group before (1999–2002 and after (2003–2004 the amendment. As a result, we found that pre-ordinance and post-ordinance quarterly rates of AMI for Delaware residents were 451 (se = 21 and 430 (se = 21 respectively, representing a 4.7% reduction. Over the same time period, there was negligible change in the incidence of AMI for non-Delaware residents. After adjusting for population growth, the Risk Ratio (RR for asthma in Delaware residents post-ordinance was 0.95 (95% CI, 0.90 to 0.999, which represented a significant reduction (P = 0.046. By comparison, non-Delaware residents had an increased RR for asthma post-ordinance of 1.62 (95% CI, 1.46 to 1.86; P < 0.0001.The results suggest that Delaware’s comprehensive non-smoking ordinance effectively was associated with a statistically significant decrease in the incidence of AMI and asthma in Delaware residents when compared to non-Delaware residents.

    2017-11-01

    When standing and holding an earth-fixed object, galvanic vestibular stimulation (GVS) can evoke upper limb responses to maintain balance. In the present study, we determined how these responses are affected by grip context (no contact, light grip and firm grip), as well as how they are co-ordinated with the lower limbs to maintain balance. When GVS was applied during firm grip, hand and ground reaction forces were generated. The directions of these force vectors were co-ordinated such that the overall body sway response was always aligned with the inter-aural axis (i.e. craniocentric). When GVS was applied during light grip (balance control and also that the upper and lower limbs co-ordinate for an appropriate whole-body sway response. Vestibular stimulation can evoke responses in the arm when it is used for balance. In the present study, we determined how these responses are affected by grip context, as well as how they are co-ordinated with the rest of the body. Galvanic vestibular stimulation (GVS) was used to evoke balance responses under three conditions of manual contact with an earth-fixed object: no contact, light grip (vestibular-evoked balance responses. Furthermore, they demonstrate that upper and lower-limb forces are co-ordinated to produce an appropriate whole-body sway response. © 2017 The Authors.

    2017-08-01

    Visual analysis is the primary method for detecting the presence of treatment effects in graphically displayed single-case data and it is often referred to as the "gold standard." Although researchers have developed standards for the application of visual analysis (e.g., Horner et al., 2005), over- and underestimation of effect size magnitude is not uncommon among analysts. Several characteristics have been identified as potential contributors to these errors; however, researchers have largely focused on characteristics of the data itself (e.g., autocorrelation), paying less attention to characteristics of the graphic display which are largely in control of the analyst (e.g., ordinate scaling). The current study investigated the impact that differences in ordinate scaling, a graphic display characteristic, had on experts' accuracy in judgments regarding the magnitude of effect present in single-case percentage data. 32 participants were asked to evaluate eight ABAB data sets (2 each presenting null, small, moderate, and large effects) along with three iterations of each (32 graphs in total) in which only the ordinate scale was manipulated. Results suggest that raters are less accurate in their detection of treatment effects as the ordinate scale is constricted. Additionally, raters were more likely to overestimate the size of a treatment effect when the ordinate scale was constricted. Copyright © 2017 Society for the Study of School Psychology.

  5. Anatomical localization of electrophysiological recording sites by co-ordinate transformation.

    Sinex, D G

    1997-07-18

    A method for estimating the anatomical locations of the units recorded in electrophysiological mapping experiments is described. A total of three locations must be marked by dye injections or electrolytic lesions and identified in tissue sections. From those locations, equations are derived to translate, scale, and rotate the three-dimensional co-ordinates of the recording sites, so that they are correct for a second, three-dimensional co-ordinate system based on the anatomy of the mapped structure. There is no limit to the number of recording sites that can be localized. This differs from methods that require a dye injection or lesion to be made at the exact location at which a particular unit was recorded. The accuracy of the transformed co-ordinates is limited by the accuracy with which the co-ordinates can be measured: in test measurements and in the experiments for which this algorithm was developed, the computed co-ordinates were typically accurate to within 100 microns or less.

  6. Development of three-dimensional program based on Monte Carlo and discrete ordinates bidirectional coupling method

    2013-01-01

    The Monte Carlo (MC) and discrete ordinates (SN) are the commonly used methods in the design of radiation shielding. Monte Carlo method is able to treat the geometry exactly, but time-consuming in dealing with the deep penetration problem. The discrete ordinate method has great computational efficiency, but it is quite costly in computer memory and it suffers from ray effect. Single discrete ordinates method or single Monte Carlo method has limitation in shielding calculation for large complex nuclear facilities. In order to solve the problem, the Monte Carlo and discrete ordinates bidirectional coupling method is developed. The bidirectional coupling method is implemented in the interface program to transfer the particle probability distribution of MC and angular flux of discrete ordinates. The coupling method combines the advantages of MC and SN. The test problems of cartesian and cylindrical coordinate have been calculated by the coupling methods. The calculation results are performed with comparison to MCNP and TORT and satisfactory agreements are obtained. The correctness of the program is proved. (authors)

    Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and non-idiopathic autism. Individuals with FXS present with a behavioral phenotype of specific and selective deficits in an array of cognitive skills. Disruption of number processing and arithmetic abilities in higher-functioning adults and female adolescents with FXS has been well established. Still, both numerical skills and developmentally antecedent cognitive processes have just begun to be investigated in toddlers with FXS. The goal of the current study was to assess how very young children with FXS respond to ordinal relationships among numerical magnitudes. Infrared eye-tracking was used to explore infants' novelty recognition during passive viewing of ordinal numerical sequences; t-tests were used to analyze group differences in looking time. Ordinal recognition of numerical magnitudes is significantly impaired in young toddlers with FXS. This study is the first to experimentally evaluate early number sense and ordinal recognition in toddlers with FXS, and our findings reveal that ordinal recognition of numerical magnitudes is significantly impaired in young toddlers with FXS, suggesting that later arithmetic impairments associated with FXS may have their origins in a developmental impairment of this more basic aspect of numerical cognition.

    To determine the economic impact of the Iowa City, Iowa, smoke-free restaurant ordinance (IC-SFRO) using an immediate and novel approach. In this retrospective study, food permit licensure served as the measure to assess the IC-SFRO impact. The Iowa City experience provided an excellent experimental setting, as the ordinance was enacted March 1, 2002, and repealed May 7, 2003, because of preemption. The city of Coralville served as a natural control, as it is contiguous to Iowa City, has similar population demographics, and has never enacted a smoke-free restaurant ordinance. Food permit licensure data for all Iowa City and Coralville restaurants were obtained from the Johnson County Health Department. Differences in restaurant volatility were assessed using Fisher's exact probability test. The number of restaurants increased in both Iowa City and Coralville throughout the ordinance period. The ratio of the total number of restaurants in Iowa City to the total number of restaurants in the Iowa City-Coralville metropolitan area remained stable. The proportion of restaurants for each city did not differ significantly during the preordinance, ordinance, and postordinance periods. The IC-SFRO did not adversely impact the restaurant industry in terms of restaurant closures. The Iowa legislature was urged to draft evidence-based legislation, such as amending preemption of the IC-SFRO, to protect and promote the health of its communities.

    Full Text Available Il notevole incremento di studi critici sulla Poetica Cognitiva sta riscattandola dall’accusa di offrire soltanto una nuova e seducente terminologia, guadagnandole invece la dignità di metodologia scientifica. Mosso dall’interesse che il fenomeno della integrazione concettuale (blending suscita, il mio intervento propone una lettura del film La vita è bella di Roberto Benigni proprio in funzione del suo organizzarsi intorno a un blending che ne sostiene l’intero impianto ideativo. Il film è stato molto criticato, oltre che per un certo impaccio tecnico nella messa in scena, per il fatto di condurre un racconto di morte e sterminio attraverso un punto di vista comico. Attraverso l’applicazione del blending, insieme ad altri strumenti di analisi classica, cercherò di dimostrare come la strutturazione del racconto intorno alla duplice contaminazione di realtà e fantasia, comico e tragico, lo sottrae dal rischio di scivolare nel melodramma e nel patetismo, mantenendo alta l’empatia dello spettatore. La mia lettura sottolinea dunque come tutto il film sia costruito su un continuo blending, e ne evidenzia le modalità di realizzazione, dimostrando, attraverso un’opera ampiamente nota e di vasto consenso, come le scienze cognitive possano offrire validi strumenti di analisi che precisano pregresse intuizioni critiche e illuminano zone dell’opera d’arte rimaste in ombra o confinate alla valutazione estetica.

The permanent plots are selected according to the directive of EU Regulation no. 1091/94 so as to include the major forest ecosystems in Italy, and are distributed over the whole country. Each covers an area of 10-100 ha, within which two sample units of 2,500 m2 are designated. The main dominant species are Fagus sylvatica (10 areas, Picea abies (6, Quercus cerris (5, Quercus ilex (4, Quercus petraea (1 Quercus robur (1 and Abies alba (1. The first six years of the CONECOFOR Programme have resulted in a detailed, organic description of the main forest ecosystems in Italy. Implementation of the programme has meant that we are now in possession of a reasonably complete knowledge of the ecological characteristics of 17 different Italian forest communities ranging from the Alps to Sicily. The assessment and monitoring of forest health represent a key point for environmental policy-makers and for the management of environmental resources in the framework of sustainable development.

    2012-01-01

    On August 9, 2010, Santa Clara County CA became the first U.S. jurisdiction to implement an ordinance that prohibits the distribution of toys and other incentives to children in conjunction with meals, foods, or beverages that do not meet minimal nutritional criteria. Restaurants had many different options for complying with this ordinance, such as introducing more healthful menu options, reformulating current menu items, or changing marketing or toy distribution practices. To assess how ordinance-affected restaurants changed their child menus, marketing, and toy distribution practices relative to non-affected restaurants. Children's menu items and child-directed marketing and toy distribution practices were examined before and at two time points after ordinance implementation (from July through November 2010) at ordinance-affected fast-food restaurants compared with demographically matched unaffected same-chain restaurants using the Children's Menu Assessment tool. Affected restaurants showed a 2.8- to 3.4-fold improvement in Children's Menu Assessment scores from pre- to post-ordinance with minimal changes at unaffected restaurants. Response to the ordinance varied by restaurant. Improvements were seen in on-site nutritional guidance; promotion of healthy meals, beverages, and side items; and toy marketing and distribution activities. The ordinance appears to have positively influenced marketing of healthful menu items and toys as well as toy distribution practices at ordinance-affected restaurants, but did not affect the number of healthful food items offered.

    2016-11-01

    Full Text Available Il presente contributo si propone di ripercorrere le tappe del rapporto letterario tra Martin Amis e Primo Levi, sottolineando l’attenzione dello scrittore inglese nei confronti dei testi di Levi. Come Amis stesso scrive più volte, Levi fu per lui una delle letture fondamentali nel suo percorso di ricerca letteraria; e nella Postfazione di una delle sue opere principali, Time’s arrow (La freccia del tempo, l’autore richiama per ben due volte l’attenzione su Levi, da un lato, ritenendo che senza le letture leviane non avrebbe potuto scrivere il suo romanzo, e dall’altro, avvertendo il lettore che il titolo pensato originariamente era un’espressione leviana, La natura dell’offesa (oggi secondo titolo de La freccia del tempo. Partendo da questi presupposti si nota come, nel racconto Trattamento di quiescenza della raccolta Storie Naturali, Levi parla tangenzialmente di uno scorrere del tempo al contrario e con una causalità inversa, nello stesso modo in cui Amis, in maniera più sistematica e precisa, costruisce per intero il suo romanzo. Dunque si potrebbe ipotizzare che Amis si sia ispirato non solo al Levi di Se questo è un uomo, La tregua e I sommersi e i salvati per il tema del suo romanzo (e cioè la barbarie nazista, ma anche al Levi dei racconti per il modo tutto particolare di narrare la sua storia. Del resto, la scelta di scrivere il romanzo ‘al contrario’ è funzionale al tema: solo in un mondo con un tempo e una causalità ‘al contrario’ la barbarie dei campi di concentramento sarebbe giustificabile. The purpose of this paper is to explore the literary relationship between Martin Amis and Primo Levi, highlighting how the English writer directed his attention to Levi’s works. As Amis himself often writes, Levi was one of his fundamental readings in his literary research; in the Afterword of one of his masterpieces, Time’s Arrow, the author mentions Levi twice: on the one hand, he claims that he could not

    Science.gov (United States)

    Ellis, G A; Hobart, R L; Reed, D F

    1996-01-01

    As part of a comprehensive tobacco education campaign, local health departments throughout California have been engaged in the process of enacting local clean indoor air ordinances to protect the public from the effects of secondhand smoke. This paper describes how a Northern California Bay Area health department worked with city and county governments to pass ordinances in the face of persistent tobacco industry opposition. The key strategies used by the health department included organizing broad-based coalitions, achieving effective use of the media, and educating the business community. Tobacco industry tactics included establishing local front groups that launched a massive misinformation campaign to frighten local businesses into believing that passage of an ordinance would adversely affect their business. Finally, the authors discuss how the tobacco industry has created a climate through state and national legislative activity to undermine the ability of local health departments to pursue effective tobacco control policies, most notably through preemptive legislation.

    Mouriño, Helena

    2013-10-01

    In Tourism Research, ordinal regression models are becoming a very powerful tool in modelling the relationship between an ordinal response variable and a set of explanatory variables. In August and September 2010, we conducted a pioneering Tourist Survey in Sintra, Portugal. The data were obtained by face-to-face interviews at the entrances of the Palaces and Parks of Sintra. The work developed in this paper focus on two main points: tourists' perception of the entrance fees; overall level of satisfaction with this heritage site. For attaining these goals, ordinal regression models were developed. We concluded that tourist's nationality was the only significant variable to describe the perception of the admission fees. Also, Sintra's image among tourists depends not only on their nationality, but also on previous knowledge about Sintra's World Heritage status.

  19. Discrete Ordinates Method-Like Computation with Group Condensation and Angle Collapsing in Transport Theory

    International Nuclear Information System (INIS)

    Won, Jong Hyuck; Cho, Nam Zin

    2010-01-01

    In group condensation for transport method, it is well-known that angle-dependent total cross section is generated. To remove this difficulty on angledependent total cross section, we normally perform the group condensation on total cross section by using scalar flux weight as used in neutron diffusion method. In this study, angle-dependent total cross section is directly applied to the discrete ordinates method. In addition, angle collapsing concept is introduced based on equivalence to reduce calculational burden of transport computation. We also show numerical results for a heterogeneous 1-D slab problem with local/global iteration, in which fine-group discrete ordinates calculation is used in local problem while few-group angle collapsed discrete ordinates calculation is used in global problem iteratively

    The British Geological Survey is reponsible for co-ordinating the Department of the Environment's programme of natural analogue studies of radionuclide migration, a research programme that involved both UK and overseas sites. Co-ordination is achieved through the UK Natural Analogue Co-ordinating Group (NACG) which was established in October 1986. It has met three times to date and its function is to ensure that the different research projects have an integrated purpose aimed at improving and applying our understanding of natural geochemical processes in a way that will increase our confidence in long-term modelling predictions. Improved modelling prediction of radionuclide transport in the geosphere will directly benefit the performance and safety assessments of proposed radioactive waste repositories. (author)

    2000-01-01

    A non-intrusive method is described which can be used to determine the forms of oral structures. It is based on the digitising of standard replicas with a co-ordinate-measuring machine. Supporting software permits a mathematical model of the surface to be reconstructed and visualised from captured three-dimensional co-ordinates. A series of surface data sets can be superposed into a common reference frame without the use of extrinsic markers, allowing changes in the shapes of oral structures to be quantified accurately over an extended period of time. The system has found numerous applications.

    Neutral hydrogen transport in a fully ionized two-dimensional tokamak plasma was examined using discrete ordinates and contrasted with earlier analyses. In particular, curvature effects induced by toroidal geometries and ray effects caused by possible source localization were investigated. From an overview of the multigroup discrete-ordinates approximation, methodology in two-dimensional cylindrical geometry is detailed, mesh and plasma zoning procedures are sketched, and the piecewise polynomial solution algorithm on a triangular domain is obtained. Toroidal effects and comparisons as related to reaction rates and perticle spectra are examined for various model and source configurations

    This work revisits the problem of ray effects in discrete ordinates calculations that frequently occurs in two- and three-dimensional systems which contain isolated sources within a highly absorbing medium. The effectiveness of using a first collision source or a second collision source are analyzed as possible remedies to mitigate this problem. The first collision and second collision sources are generated by three-dimensional Monte Carlo calculations that enables its application to a variety of source configurations, and the results can be coupled to a two- or three-dimensional discrete ordinates transport code.

  8. Inferences for Joint Modelling of Repeated Ordinal Scores and Time to Event Data

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available In clinical trials and other follow-up studies, it is natural that a response variable is repeatedly measured during follow-up and the occurrence of some key event is also monitored. There has been a considerable study on the joint modelling these measures together with information on covariates. But most of the studies are related to continuous outcomes. In many situations instead of observing continuous outcomes, repeated ordinal outcomes are recorded over time. The joint modelling of such serial outcomes and the time to event data then becomes a bit complicated. In this article we have attempted to analyse such models through a latent variable model. In view of the longitudinal variation on the ordinal outcome measure, it is desirable to account for the dependence between ordered categorical responses and survival time for different causes due to unobserved factors. A flexible Monte Carlo EM (MCEM method based on exact likelihood is proposed that can simultaneously handle the longitudinal ordinal data and also the censored time to event data. A computationally more efficient MCEM method based on approximation of the likelihood is also proposed. The method is applied to a number of ordinal scores and survival data from trials of a treatment for children suffering from Duchenne Muscular Dystrophy. Finally, a simulation study is conducted to examine the finite sample properties of the proposed estimators in the joint model under two different methods.

    2006-11-01

    We present an ordinal logistic regression model for identification of items with differential item functioning (DIF) and apply this model to a Mini-Mental State Examination (MMSE) dataset. We employ item response theory ability estimation in our models. Three nested ordinal logistic regression models are applied to each item. Model testing begins with examination of the statistical significance of the interaction term between ability and the group indicator, consistent with nonuniform DIF. Then we turn our attention to the coefficient of the ability term in models with and without the group term. If including the group term has a marked effect on that coefficient, we declare that it has uniform DIF. We examined DIF related to language of test administration in addition to self-reported race, Hispanic ethnicity, age, years of education, and sex. We used PARSCALE for IRT analyses and STATA for ordinal logistic regression approaches. We used an iterative technique for adjusting IRT ability estimates on the basis of DIF findings. Five items were found to have DIF related to language. These same items also had DIF related to other covariates. The ordinal logistic regression approach to DIF detection, when combined with IRT ability estimates, provides a reasonable alternative for DIF detection. There appear to be several items with significant DIF related to language of test administration in the MMSE. More attention needs to be paid to the specific criteria used to determine whether an item has DIF, not just the technique used to identify DIF.

  1. The midwives ordinance of Palestine, 1929: historical perspectives and current lessons.

    Science.gov (United States)

    Katvan, Eyal; Bartal, Nira

    2010-06-01

    Until 1929, midwifery in Palestine was relatively open to anyone and only partially regulated by the 1918 Public Health Ordinance, legislated shortly after the beginning of British rule. This article describes the factors that guided the shaping of midwifery and suggests possible sources of inspiration for the British legislator in crafting the Midwives Ordinance in 1929, including American, local (Jews and Arabs), and British ones. The Midwives Ordinance reflects the adjustment of midwifery to changes in the society that evolved under the British Mandate. The ordinance shows how the modern midwife's role contracted relative to the traditional one, in the context of social processes in other countries, east and west. This historical research project is based on interviews, archive documents and research literature. It analyzes the British interests in regulating midwifery, including the rationale of preserving public health and reducing infant mortality, against a background of political power struggles as well as cultural, social and professional diversity in Palestine (the tensions between the powers of doctors, nurses, and pharmacists).

    In the United States, smoking is the leading cause of death - having a mortality rate of approximately 435,000 people in 2000-accounting for 8.1% of all US deaths recorded that year. Consequently, we analyzed the Delaware Hospital Discharge Database, and identified state and non-state residents discharged with AMI or asthma for the years 1999 to 2004. Statistical data analysis compared the incidence of AMI or asthma for each group before (1999-2002) and after (2003-2004) the amendment. As a result, we found that pre-ordinance and post-ordinance quarterly rates of AMI for Delaware residents were 451 (se = 21) and 430 (se = 21) respectively, representing a 4.7% reduction. Over the same time period, there was negligible change in the incidence of AMI for non-Delaware residents. After adjusting for population growth, the Risk Ratio (RR) for asthma in Delaware residents post-ordinance was 0.95 (95% CI, 0.90 to 0.999), which represented a significant reduction (P = 0.046). By comparison, non-Delaware residents had an increased RR for asthma post-ordinance of 1.62 (95% CI, 1.46 to 1.86; P asthma in Delaware residents when compared to non-Delaware residents.

    Full Text Available Episcopal Church of the USA in 1976 adopted a positive resolution (1976-B300 regarding women’s ordination to the priesthood and episcopacy. The Church thus legalizes the experience of the Anglican community of the East coast: Philadelphia and Washington where in July 1974 and September 1975, took place women’s ordination. The article is devoted to the history of these ordinations, public reactions to them and theological discussions concerning the permissibility of female ordination in the Episcopal community of the first half of the 1970s. The research is based on the offi cial reports of the Episcopal Church. Believe in the Divine will on the vocation of women to the priesthood was associated with transformation of the Western society: women’s struggle for their rights and public struggle against race discrimination. The Anglican bishops were concerned about the problem of adaptation of the new ministry to modern conditions: the 1970s became a period of transition from traditional to post-Christian society in which gender was considered as a new social function. It will transform the Anglican community where the priesthood will become a form of ministry to the parish and in these conditions women can be ordained .

    Full Text Available Paul Flandrin (Lione 1811- Parigi 1902 è un pittore dalla lunga carriera, i cui inizi si snodano tra la formazione presso l’Académie des Beaux Arts di Lione e l’atelier di Ingres a Parigi. Sarà però durante il viaggio in Italia (1834-1838 che il pittore individuerà la sua precisa vocazione di pittore di paesaggio. Il periodo trascorso a Roma, non pensionnaire di Villa Medici ma assiduo frequentatore della Accademia di Francia, all’epoca diretta dal suo maestro, è significativo per individuare le prime prove di un artista che si pone tra l’influenza di Corot e l’insegnamento di Ingres. Per un pittore di educazione neoclassica, quanto conta l’esperienza italiana? Per un allievo di Ingres, cosa significa la scelta del paesaggio? Per un paysagiste che arriva a Roma negli anni Trenta, in cosa consiste l’eredità di Corot? L’articolo tenta di dare risposta a queste domande attraverso l’individuazione di alcune tappe fondamentali della produzione grafica e pittorica di Paul Flandrin compresa negli anni del soggiorno italiano. L’indagine si concentra sulla comprensione del metodo di lavoro dell’artista, dalla percezione della natura vista e studiata dal vero alla ricomposizione in atelier. Dall’analisi emerge la figura complessa di un pittore di formazione neoclassica che opera nel XIX secolo inoltrato.

  20. Natura pedagogica e rilevanza politica del concetto di 'composizione musicale'

    Directory of Open Access Journals (Sweden)

    Luca Aversano

    2013-12-01

    Full Text Available Il contributo discute ed evidenzia le relazioni che intercorrono tra il concetto di composizione musicale e gli àmbiti della pedagogia e della politica. A partire da un'analisi storico-lessicologica della parola "composizione" vengono illustrate le variabili semantiche del termine e  il tratto comune che le caratterizza, ossia il riferimento costante a un principio razionale di aggregazione di elementi diversi, a cui l'attività compositiva, nelle sue possibili esplicazioni e in quanto progetto di organizzazione sonora, è sempre riconducibile. La composizione musicale viene dunque interpretata come metafora-chiave di una possibile strada per la soluzione di un problema molto urgente della contemporaneità: come tenere insieme persone provenienti da culture diverse, come combinare identità differenti in una nuova identità comune.D'altro canto, la musica d'arte, nel suo oscillare tra testo notato e interpretazione, è intimamente affine al paradigma giuridico che sta a fondamento di qualsiasi organismo sociale.

  1. La complessità del diverso nella piattezza di Flatland

    2015-07-01

    Full Text Available Abstract – This paper proposes an analysis of Edwin Abbott Abbott’s Flatland: a Romance of Many Dimensions (1884. In particular, it focuses on the first section of the novel, This World, which is interpreted as a satire of the Victorian society. In fact, the fictional world of Flatland appears to have been built exactly upon the middle class ideological standpoint. This is ironically translated into a series of strategies – both at a territorial and at a relational level – through which this group tries to maintain its hegemonic social position and, at the same time, to distance all those elements that may deviate from its image of respectability. This is investigated with special regard to the characters of the Irregular and of the isosceles triangle, towards which the middle class shows an attitude of closure. Such behaviour is nothing else but the satirical depiction of its ambiguous relationship with Otherness.Sommario – Questo saggio propone un’analisi di Flatland: a Romance of Many Dimensions (1884 di Edwin Abbott Abbott. Nello specifico, esso si sofferma sulla prima sezione del romanzo, This World, interpretata quale satira della società vittoriana. Difatti, il mondo fantastico di Flatland sembra essere stato costruito proprio sulla base dell’ideologia della middle class, che è ironicamente tradotta in una serie di strategie – su un piano sia territoriale sia relazionale – tramite le quali questo gruppo tenta di mantenere l’egemonia della sua posizione sociale e, al contempo, di allontanare tutti quegli elementi che potrebbero deviare dalla sua immagine di rispettabilità. Ciò è esaminato con particolare riferimento ai personaggi dell’Irregolare e del triangolo isoscele, verso i quali la middle class mostra un atteggiamento di chiusura. Tale comportamento non è altro che la satirica raffigurazione del suo ambiguo rapporto con l’Alterità.

  3. Identification of a cis-regulatory element by transient analysis of co-ordinately regulated genes

    Directory of Open Access Journals (Sweden)

    Allan Andrew C

    2008-07-01

    Full Text Available Abstract Background Transcription factors (TFs co-ordinately regulate target genes that are dispersed throughout the genome. This co-ordinate regulation is achieved, in part, through the interaction of transcription factors with conserved cis-regulatory motifs that are in close proximity to the target genes. While much is known about the families of transcription factors that regulate gene expression in plants, there are few well characterised cis-regulatory motifs. In Arabidopsis, over-expression of the MYB transcription factor PAP1 (PRODUCTION OF ANTHOCYANIN PIGMENT 1 leads to transgenic plants with elevated anthocyanin levels due to the co-ordinated up-regulation of genes in the anthocyanin biosynthetic pathway. In addition to the anthocyanin biosynthetic genes, there are a number of un-associated genes that also change in expression level. This may be a direct or indirect consequence of the over-expression of PAP1. Results Oligo array analysis of PAP1 over-expression Arabidopsis plants identified genes co-ordinately up-regulated in response to the elevated expression of this transcription factor. Transient assays on the promoter regions of 33 of these up-regulated genes identified eight promoter fragments that were transactivated by PAP1. Bioinformatic analysis on these promoters revealed a common cis-regulatory motif that we showed is required for PAP1 dependent transactivation. Conclusion Co-ordinated gene regulation by individual transcription factors is a complex collection of both direct and indirect effects. Transient transactivation assays provide a rapid method to identify direct target genes from indirect target genes. Bioinformatic analysis of the promoters of these direct target genes is able to locate motifs that are common to this sub-set of promoters, which is impossible to identify with the larger set of direct and indirect target genes. While this type of analysis does not prove a direct interaction between protein and DNA

    According to the authors, section 4 StrlSchV does not apply, the case has to be handled applying section 3 StrlSchV (Radiation Protection Ordinance). This means that the storage, treatment and disposal of the radioactive whey concentrate is subject to licensing. Disposal as radioactive waste, however, will require a licence only if the limit given in section 4 IV, No. 2 lit. e, the 10 -4 -fold of the allowed radioactivity per gramme (i.e. 3700 Bq/kg) is exceeded. The averaged radioactivity data measured do exceed this limit.

    The authors reanalyze the data of a study by S. M. Elias and R. J. Loomis (2004), which aimed to determine how an instructor's gender may influence his or her ability to gain student compliance. S. M. Elias and R. J. Loomis observed few significant gender effects using traditional multivariate analyses of variance. The authors reanalyze this data using the more appropriate statistical techniques for detecting ordinal interactions recommended by M. J. Strube and P. Bobko (1989) and S. M. Elias (2004). An ordinal interaction occurs when 1 cell of a 2 x 2 design is responsible for a significant interaction (e.g., female instructors suffering only when rated by male students). Reanalysis of the data resulted in more robust findings.

    2016-01-01

    Full Text Available In this paper we analyze application of contemporary methods of insulation co-ordination and the enlargement law in designing a GM counting tube. It has been shown that by applying insulation co-ordination methods the counting tube can be optimally dimensioned. The application of the enlargement law was demonstrated in generalizing the results of test obtained by the GM tube to those obtained by the counting tube with m-times greater dimensions. The investigations were conducted both theoretically and by experiment. Using theoretical analysis, we derived the expressions that may be applied if a performance function of a random variable breakdown voltage is known. The experiments were conducted on a GM counter model under well controlled laboratory conditions.

    Liu, Chengcheng; Ratcliffe, Sarah J.; Guo, Wensheng

    2016-01-01

    We extend a random pattern mixture joint model for longitudinal ordinal outcomes and informative dropouts. The patients are generalized to ”pattern” groups based on known covariates that are potential surrogated for the severity of the underlying condition. The random pattern effects are defined as the latent effects linking the dropout process and the ordinal longitudinal outcome. Conditional on the random pattern effects, the longitudinal outcome and the dropout times are assumed independent. Estimates are obtained via the EM algorithm. We applied the model to the end-stage renal disease (ESRD) data. Anemia was found to be significantly affected by baseline iron treatment when the dropout information was adjusted via the study model; as opposed to an independent or shared parameter model. Simulations were performed to evaluate the performance of the random pattern mixture model under various assumptions. PMID:25894456

    Barichello, L.B.; Siewert, C.E.

    1998-01-01

    In this work concerning steady-state radiative-transfer calculations in plane-parallel media, the equivalence between the discrete ordinates method and the spherical harmonics method is proved. More specifically, it is shown that for standard radiative-transfer problems without the imposed restriction of azimuthal symmetry the two methods yield identical results for the radiation intensity when the quadrature scheme for the discrete ordinates method is defined by the zeros of the associated Legendre functions and when generalized Mark boundary conditions are used to define the spherical harmonics solution. It is also shown that, with these choices for a quadrature scheme and for the boundary conditions, the two methods can be formulated so as to require the same computational effort. Finally a justification for using the generalized Mark boundary conditions in the spherical harmonics solution is given

    The efficiency of the on-site emergency organization in German nuclear power plants is tested regularly through emergency exercises. To achieve federal harmonization on a high level of quality a handbook for the planning, co-ordination and evaluation of such exercises has been developed in the frame of the regulatory investigation programme. In this handbook requirements are set out for emergency training. Key elements are a modular structure, rules to be observed and guidance for post-exercise evaluation. (orig.) [de

  20. Discrete ordinate solution of the radiative transfer equation in the 'polarization normal wave representation'

    1991-01-01

    The transfer equations for normal waves in finite, inhomogeneous and plane-parallel magnetoactive media are solved using the discrete ordinate method. The physical process of absorption, emission, and multiple scattering are accounted for, and the medium may be forced both at the top and bottom boundary by anisotropic radiation as well as by internal anisotropic sources. The computational procedure is numerically stable for arbitrarily large optical depths, and the computer time is independent of optical thickness.

    An algorithm is developed for the gamma-weighted discrete ordinate two-stream approximation that computes profiles of domain-averaged shortwave irradiances for horizontally inhomogeneous cloudy atmospheres. The algorithm assumes that frequency distributions of cloud optical depth at unresolved scales can be represented by a gamma distribution though it neglects net horizontal transport of radiation. This algorithm is an alternative to the one used in earlier studies that adopted the adding method. At present, only overcast cloudy layers are permitted.

    The Fourier transform infrared (FT-IR) and Raman (FT-R) spectra of 2-aminopyridine and 2-amino picoline were recorded and the observed frequencies were assigned to various modes of vibration in terms of fundamentals by assuming Cs point group symmetry. A normal co-ordinate analysis was also carried out for the proper assignment of the vibrational frequencies using simple valence force field. A complete vibrational analysis is presented here for the molecules and the results are briefly discussed.

    The discrete ordinate method for the resolution of the radiative transfer equation is developed. We show that the construction of a quasi-analytical solution to the corresponding matrix diagonalization problem reduces the time calculation and allows the use of more dense discrete frequency and angle grids. Comparison with previous work is made, showing that the present method reduces by more than a factor of ten the computational time, and is more appropriate in all cases

    A generalization of the one-group Spectral Green's Function (SGF) method is developed for multigroup, slab-geometry discrete ordinates (S N ) problems. The multigroup SGF method is free from spatial truncation errors; it generated numerical values for the cell-edge and cell-average angular fluxes that agree with the analytic solution of the multigroup S N equations. Numerical results are given to illustrate the method's accuracy

    The conventional discrete ordinates approximation to the Boltzmann transport equation can be described in a matrix form. Specifically, the within-group scattering integral can be represented by three components: a moment-to-discrete matrix, a scattering cross-section matrix and a discrete-to-moment matrix. Using and extending these entities, we derive and summarize the matrix representations of the second-order transport equations.

    To mitigate the damages of natural hazards, policy responses can be beneficial only if they are effective. Using a self-administered survey approach, this paper focuses on the adherence to local fertilizer ordinances (i.e., county or municipal rules regulating the application of fertilizer to private lawns or facilities such as golf courses) implemented in jurisdictions along the Southwest Florida coast in response to hazardous blooms of Florida red tides (Karenia brevis). These ordinances play a role in the context of evolving programs of water pollution control at federal, state, water basin, and local levels. With respect to policy effectiveness, while the strength of physical linkages is of critical importance, the extent to which humans affected are aware of and adhere to the relevant rules, is equally critical. We sought to understand the public's depth of understanding about the rationales for local fertilizer ordinances. Respondents in Sarasota, Florida, were asked about their fertilizer practices in an area that has experienced several major blooms of Florida red tides over the past two decades. A highly educated, older population of 305 residents and "snowbirds" reported relatively little knowledge about a local fertilizer ordinance, its purpose, or whether it would change the frequency, size, or duration of red tides. This finding held true even among subpopulations that were expected to have more interest in or to be more knowledgeable about harmful algal blooms. In the face of uncertain science and environmental outcomes, and with individual motivations at odds with evolving public policies, the effectiveness of local community efforts to decrease the impacts of red tides may be compromised. Targeted social-science research on human perceptions about the risks of Florida red tides and education about the rationales for potential policy responses are warranted.

    Many important phenotypic traits in plants are ordinal. However, relatively little is known about the methodologies for ordinal trait association studies. In this study, we proposed a hierarchical generalized linear mixed model for mapping quantitative trait locus (QTL) of ordinal traits in crop cultivars. In this model, all the main-effect QTL and QTL-by-environment interaction were treated as random, while population mean, environmental effect and population structure were fixed. In the estimation of parameters, the pseudo data normal approximation of likelihood function and empirical Bayes approach were adopted. A series of Monte Carlo simulation experiments were performed to confirm the reliability of new method. The result showed that new method works well with satisfactory statistical power and precision. The new method was also adopted to dissect the genetic basis of soybean alkaline-salt tolerance in 257 soybean cultivars obtained, by stratified random sampling, from 6 geographic ecotypes in China. As a result, 6 main-effect QTL and 3 QTL-by-environment interactions were identified.

    There is no safe level of exposure to tobacco smoke. More than 60 Mississippi communities have passed smoke-free ordinances in the past six years. Opponents claim that these ordinances harm local businesses. Mississippi law allows municipalities to place a tourism and economic development (TED) tax on local restaurants and hotels/motels. The objective of this study is to examine the impact of these ordinances on TED tax revenues. This study applies a pre/post quasi-experimental design to compare TED tax revenue before and after implementing ordinances. Descriptive analyses indicated that inflation-adjusted tax revenues increased during the 12 months following implementation of smoke-free ordinances while there was no change in aggregated control communities. Multivariate fixed-effects analyses found no statistically significant effect of smoke-free ordinances on hospitality tax revenue. No evidence was found that smoke-free ordinances have an adverse effect on the local hospitality industry.

  14. Variable discrete ordinates method for radiation transfer in plane-parallel semi-transparent media with variable refractive index

    Science.gov (United States)

    Sarvari, S. M. Hosseini

    2017-09-01

    The traditional form of discrete ordinates method is applied to solve the radiative transfer equation in plane-parallel semi-transparent media with variable refractive index through using the variable discrete ordinate directions and the concept of refracted radiative intensity. The refractive index are taken as constant in each control volume, such that the direction cosines of radiative rays remain non-variant through each control volume, and then, the directions of discrete ordinates are changed locally by passing each control volume, according to the Snell's law of refraction. The results are compared by the previous studies in this field. Despite simplicity, the results show that the variable discrete ordinate method has a good accuracy in solving the radiative transfer equation in the semi-transparent media with arbitrary distribution of refractive index.

    Full Text Available La retorica è generalmente considerata come un ente quasi assoluto, mentre la sua forza, cioè il suo effetto, risulta dalla ricezione, dal pubblico con il quale le opere andranno confrontandosi. Analizzeremo le reazioni tedesche suscitate dalle traduzioni di due romanzi che, alla loro pubblicazione in Francia, hanno provocato in un caso uno scandalo (Les particules élémentaires di Michel Houellebecq, e nell’altro risposte clamorose (Les bienveillantes de Jonathan Littell, al punto che di ambedue si parlava in Germania ancora prima che ne uscisse la traduzione. Bisognava aspettarsi una sensibilità ben specifica nei confronti dell’opera di Littell, consistente nelle finte memorie di un ufficiale della SS, che però ha oltrepassato le attese. Più sorprendente ancora la risonanza delle Elementarteilchen: la cornice del romanzo, evocando una società dove sessualità e riproduzione sono sostituite dalla clonazione, sebbene considerata come “inutile” in Francia, si è ritrovata al centro dei dibattiti in Germania, dove Houellebecq ha addirittura acquisito – per un breve tempo – la reputazione di “Kulturphilosoph”. Così, la ricezione tedesca dei due romanzi dimostra fino a quale punto una stessa retorica possa essere recepita diversamente a seconda del contesto etico-politico.

    La scienza è un’esaltante avventura che è costume raccontare attraverso le gesta dei grandi. Esiste però un’altra storia, altrettanto avvincente ma con poca voce, scritta dai tanti gregari e potenziali campioni cui la sorte, spesso nemmeno troppo cieca, ha negato la gloria. Questo libro parla di uno di loro e del suo piccolo mondo sulla collina di Capodimonte, a Napoli. È la parabola di Arminio Nobile – personaggio notevole eppure poco noto dell’astronomia italiana – svolta sulla scena della nascente astrofisica, in una stagione di grandi transizioni per il Mezzogiorno. Arminio, che era figlio di Giuseppina Guacci, figura di spicco della cultura pre-risorgimentale, e di un valente astronomo della Specola di Capodimonte, scelse di votarsi allo studio del cielo. Osservatore instancabile, appassionato e genialoide, aveva le carte in regola e le motivazioni per “sfondare”, ma la fortuna non gli arrise: più volte si beffò di lui, spingendolo su vicoli ciechi che la sua testardaggine gli impedì...

  17. Deterministic absorbed dose estimation in computed tomography using a discrete ordinates method

    Norris, Edward T.; Liu, Xin; Hsieh, Jiang

    2015-01-01

    Purpose: Organ dose estimation for a patient undergoing computed tomography (CT) scanning is very important. Although Monte Carlo methods are considered gold-standard in patient dose estimation, the computation time required is formidable for routine clinical calculations. Here, the authors instigate a deterministic method for estimating an absorbed dose more efficiently. Methods: Compared with current Monte Carlo methods, a more efficient approach to estimating the absorbed dose is to solve the linear Boltzmann equation numerically. In this study, an axial CT scan was modeled with a software package, Denovo, which solved the linear Boltzmann equation using the discrete ordinates method. The CT scanning configuration included 16 x-ray source positions, beam collimators, flat filters, and bowtie filters. The phantom was the standard 32 cm CT dose index (CTDI) phantom. Four different Denovo simulations were performed with different simulation parameters, including the number of quadrature sets and the order of Legendre polynomial expansions. A Monte Carlo simulation was also performed for benchmarking the Denovo simulations. A quantitative comparison was made of the simulation results obtained by the Denovo and the Monte Carlo methods. Results: The difference in the simulation results of the discrete ordinates method and those of the Monte Carlo methods was found to be small, with a root-mean-square difference of around 2.4%. It was found that the discrete ordinates method, with a higher order of Legendre polynomial expansions, underestimated the absorbed dose near the center of the phantom (i.e., low dose region). Simulations of the quadrature set 8 and the first order of the Legendre polynomial expansions proved to be the most efficient computation method in the authors’ study. The single-thread computation time of the deterministic simulation of the quadrature set 8 and the first order of the Legendre polynomial expansions was 21 min on a personal computer

  19. First research co-ordination meeting of the co-ordinated research programme on development of kits for radioimmunometric assays for tumour markers. Summary report

    International Nuclear Information System (INIS)

    1997-01-01

    Cancer is one of the major reasons for mortality and a great deal of research goes on in many areas related to cancer all through the world. The concept of 'tumor markers' has greatly aided the management of cancer, especially for follow up of the treated patients. Immunoassays that are used for measurement of sub-picomolar quantities of biomolecules such as hormones have been developed for the measurement of tumor markers too and these are widely used for monitoring the patients. The current co-ordinated research program on 'Development of Immunometric Assays for the Tumor Makers: PSA, free PSA and TPS' was born out of the advise from a group of specialists from the field oncology and nuclear medicine who met to discuss initially (Advisory Group Meeting, Colombo, August 1996) to identify the most appropriate markers and later (Consultants' Meeting, Glasgow, 21-25 April 1997) to identify the details of the procedure to follow. The first Research Co-ordination Meeting of this group was held in Vienna from 9-12 December 1997 to review the plans of each participant and the steps to be taken to realize the goal of this CRP. The meeting was attended by participants from the ten laboratories. The meeting discussed all salient aspects of the IRMA development for PSA and TPS. The modalities of working out the plans were thoroughly considered and the key inputs for the program to take off were identified. In conclusion, all the nine contract holding participants would develop the IRMAs for PSA (free and total) and TPS (Uruguay)

  1. A discrete ordinates approximation to the neutron transport equation applied to generalized geometries

    Energy Technology Data Exchange (ETDEWEB)

    DeHart, Mark David [Texas A & M Univ., College Station, TX (United States)

    1992-12-01

    A method for applying the discrete ordinates method for solution of the neutron transport equation in arbitary two-dimensional meshes has been developed. The finite difference approach normally used to approximate spatial derivatives in extrapolating angular fluxes across a cell is replaced by direct solution of the characteristic form of the transport equation for each discrete direction. Thus, computational cells are not restricted to the traditional shape of a mesh element within a given coordinate system. However, in terms of the treatment of energy and angular dependencies, this method resembles traditional discrete ordinates techniques. Using the method developed here, a general two-dimensional space can be approximated by an irregular mesh comprised of arbitrary polygons. The present work makes no assumptions about the orientations or the number of sides in a given cell, and computes all geometric relationships between each set of sides in each cell for each discrete direction. A set of non-reentrant polygons can therefore be used to represent any given two dimensional space. Results for a number of test problems have been compared to solutions obtained from traditional methods, with good agreement. Comparisons include benchmarks against analytical results for problems with simple geometry, as well numerical results obtained from traditional discrete ordinates methods by applying the ANISN and TWOTRAN computer programs. Numerical results were obtained for problems ranging from simple one-dimensional geometry to complicated multidimensional configurations. These results have demonstrated the ability of the developed method to closely approximate complex geometrical configurations and to obtain accurate results for problems that are extremely difficult to model using traditional methods.

  2. Discrete-ordinates quadrature sets based on linear discontinuous finite elements

    Jarrell, Joshua J.; Adams, Marvin L.

    2011-01-01

    We describe new quadrature sets based on linear discontinuous nite element (LDFE) basis functions de ned on the unit sphere. We describe the construction of these sets, demonstrate the accuracy with which they integrate polynomials in the direction cosines, and demonstrate their performance on a set of test problems. We develop the new quadrature sets by dividing the faces of a regular octahedron into equilateral triangles and projecting these onto 'spherical triangles' on the surface of the unit sphere. We choose four quadrature points per triangle and de ne LDFE interpolating basis functions in the direction cosines. A quadrature point's weight is the integral of its basis function over its triangle. Variations in the locations of the four points produce variations in the quadrature sets. The equilateral triangles can be subdivided recursively to create ner quadrature sets, including locally re ned sets that are suitable for use in adaptive algorithms. We analyze a simple one-cell problem and a more complex skewed-duct problem and compare our LDFE quadrature sets to those normally used in the neutral particle discrete-ordinate eld such as level symmetric, Gauss- Chebyshev, and Quadruple Range (QR) sets. The LDFE and QR sets show fourth-order convergence in the simple problem, while the other sets exhibit second or lower order. The LDFE sets exhibit more accurate solutions for the scalar flux in both problems and are not limited by mathematical complexity or by negativity of the discrete-ordinate weights. The same is true for results from other test problems that are not shown here. We conclude that the new LDFE quadrature sets are a promising option for discrete-ordinates transport calculations. However, we note that further studies are needed, especially in problems with highly anisotropic scattering, before the utility of these sets is fully determined. (author)

  3. Stile didascalico e verità del mito in un exemplum ovidiano : Ars amatoria 1, 623-6

    Directory of Open Access Journals (Sweden)

    Federica Bessone

    2010-11-01

    Full Text Available Nell'Ars amatoria l'uso ironico degli exempla mitologici rientra nella parodia del genere didascalico. Per dimostrare che le blanditiae piacciono anche alle donne caste e vergini, il maestro d'amore ricorda che Giunone e Atena si vergognano “ancora adesso” di non aver vinto il Giudizio di Paride. L'impiego di una formula didascalica lucreziana dà scherzosamente una pretesa di scientificità a un exemplum tratto dal mito, e da un mito spesso contestato per il suo contenuto incredibile e scandaloso. Ovidio dà una risposta polemica alla critica razionalistica del mito espressa nelle Troiane di Euripide: benché disinteressate al matrimonio, anche la sposa di Giove e la dea vergine per scelta dovevano desiderare ardentemente l'elogio della bellezza, essendo soggette come qualsiasi donna ed essere vivente alla legge della vanità universale. La prova viene dal seguito del mito stesso: lo stilema eziologico nunc quoque rimanda al proemio dell'Eneide, dove il giudizio di Paride è una delle motivazioni antiche dell'ira di Giunone, motore del poema. Il rimando al testo nazionale dei Romani garantisce la verità del mito preso a paradigma dal maestro d'amore: per quanto problematico, quel racconto mitico ha una sua realtà indubitabile; l'esistenza dell'Eneide è la prova – poetica – che l'offesa nella vanità è per Giunone una ferita che perdura. Svincolato ormai dalle sue pretese di veridicità, il mito può riaffermare qui, per gli scopi argomentativi del praeceptor amoris, la sua incontestabile verità letteraria ed ‘umana’.

  4. Case management for high-intensity service users: towards a relational approach to care co-ordination.

    McEvoy, Phil; Escott, Diane; Bee, Penny

    2011-01-01

    This study is based on a formative evaluation of a case management service for high-intensity service users in Northern England. The evaluation had three main purposes: (i) to assess the quality of the organisational infrastructure; (ii) to obtain a better understanding of the key influences that played a role in shaping the development of the service; and (iii) to identify potential changes in practice that may help to improve the quality of service provision. The evaluation was informed by Gittell's relational co-ordination theory, which focuses upon cross-boundary working practices that facilitate task integration. The Assessment of Chronic Illness Care Survey was used to assess the organisational infrastructure and qualitative interviews with front line staff were conducted to explore the key influences that shaped the development of the service. A high level of strategic commitment and political support for integrated working was identified. However, the quality of care co-ordination was variable. The most prominent operational factor that appeared to influence the scope and quality of care co-ordination was the pattern of interaction between the case managers and their co-workers. The co-ordination of patient care was much more effective in integrated co-ordination networks. Key features included clearly defined, task focussed, relational workspaces with interactive forums where case managers could engage with co-workers in discussions about the management of interdependent care activities. In dispersed co-ordination networks with fewer relational workspaces, the case managers struggled to work as effectively. The evaluation concluded that the creation of flexible and efficient task focused relational workspaces that are systemically managed and adequately resourced could help to improve the quality of care co-ordination, particularly in dispersed networks. © 2010 Blackwell Publishing Ltd.

    Perturbation theory for changes in linear and bilinear functionals of the forward and adjoint fluxes in a critical reactor has been implemented using two-dimensional discrete ordinates transport theory. The computer program DOT IV was modified to calculate the generalized functions Λ and Λ*. Demonstration calculations were performed for changes in a reaction-rate ratio and a reactivity worth caused by system perturbations. The perturbation theory predictions agreed with direct calculations to within about 2%. A method has been developed for calculating higher lambda eigenvalues and eigenfunctions using techniques similar to those developed for generalized functions. Demonstration calculations have been performed to obtain these eigenfunctions

    We present a discrete-ordinate algorithm using the matrix-exponential solution for pseudo-spherical radiative transfer. Following the finite-element technique we introduce the concept of layer equation and formulate the discrete radiative transfer problem in terms of the level values of the radiance. The layer quantities are expressed by means of matrix exponentials, which are computed by using the matrix eigenvalue method and the Pade approximation. These solution methods lead to a compact and versatile formulation of the radiative transfer. Simulated nadir and limb radiances for an aerosol-loaded atmosphere and a cloudy atmosphere are presented along with a discussion of the model intercomparisons and timings

    Discussed here is the accuracy of approximate albedo boundary conditions for energy multigroup discrete ordinates (S{sub N}) eigenvalue problems in two-dimensional rectangular geometry for criticality calculations in neutron fission reacting systems, such as nuclear reactors. The multigroup (S{sub N}) albedo matrix substitutes approximately the non-multiplying media around the core, e.g., baffle and reflector, as we neglect the transverse leakage terms within these non-multiplying regions. Numerical results to a typical model problem are given to illustrate the accuracy versus the computer running time. (author)

    A previously reported parallel performance model for Angular Domain Decomposition (ADD) of the Discrete Ordinates method for solving multidimensional neutron transport problems is revisited for further validation. Three communication schemes: native MPI, the bucket algorithm, and the distributed bucket algorithm, are included in the validation exercise that is successfully conducted on a Beowulf cluster. The parallel performance model is comprised of three components: serial, parallel, and communication. The serial component is largely independent of the number of participating processors, P, while the parallel component decreases like 1/P. These two components are independent of the communication scheme, in contrast with the communication component that typically increases with P in a manner highly dependent on the global reduced algorithm. Correct trends for each component and each communication scheme were measured for the Arbitrarily High Order Transport (AHOT) code, thus validating the performance models. Furthermore, extensive experiments illustrate the superiority of the bucket algorithm. The primary question addressed in this research is: for a given problem size, which domain decomposition method, angular or spatial, is best suited to parallelize Discrete Ordinates methods on a specific computational platform? We address this question for three-dimensional applications via parallel performance models that include parameters specifying the problem size and system performance: the above-mentioned ADD, and a previously constructed and validated Spatial Domain Decomposition (SDD) model. We conclude that for large problems the parallel component dwarfs the communication component even on moderately large numbers of processors. The main advantages of SDD are: (a) scalability to higher numbers of processors of the order of the number of computational cells; (b) smaller memory requirement; (c) better performance than ADD on high-end platforms and large number of

    1985-01-01

    An unified formalism to solve numerically, between other equation, the neutron transport in discrete ordinates, slab geometry, several energy groups and independents of time, has been developed recently. Such a formalism cover some of the conventional schemes as diamond difference, (WDD) characteristic step (SC) lineal characteristic (LC), quadratic characteristic (QC) and lineal discontinuous. Unified formation gives before hand the convergence order of the previously selected scheme. In fact it allows besides to generate a big amount of numerical schemes, with which is also possible to solve numerical equations as soon as neutron transport. The essential purpose of this work was to solve the neutron transport equations in slab geometry and discrete ordinates considering several energy groups without to take under advisement time dependence based in the above mentioned unified formalism. To reach this purpose it was necesary to design a computer code with the name TNOD1 (Neutron transport in discrete ordinates and 1 dimension) which includes each one of the schemes already pointed out. there exist two numerical schemes, also recently developed, quadratic continuous (QC) and cubic continuous (CN), although covered by unified formalism, it has been possible to include them inside this computer code without make substantial changes in its structure. In chapter I, derivative of neutron transport equation independent of time is taken, for angular flux, including boundary conditions and discontinuity. In chapter II the neutron transport equations are obtained in multigroups, independents of time, for approximation of discrete ordinates. Description of theory related with unified formalism and its relationship with mentioned discretization schemes is presented in chapter III. Chapter IV describes the computer code developed and finally, in chapter V different numerical results obtained with TNOD1 program are shown. In Appendix A theorems and mathematical arguments used

    To analyze the situation of the vacuum in the FTU tokamak, on 22/5/96 was set up a task force to identify the problem(s) and to settle the operative and cleaning procedures. The main actions of the task force were: leak tests, automatic procedure to monitor on line the state of the machine vacuum and an exhaustive analysis of the work done before. The task force reviewed the outgassing measurements of the plastic materials inserted into the machine and was decided to repeat the test on the thermocouples. The results pointed out that the thermocouples are a practically infinite reservoir of water. The outcome of the task force was a set of new procedures and recommendations during both the operation of FTU and the shutdown periods. FTU is now operating at more acceptable plasma purity. [Italiano] Il 22/5/96 fu costituita una Task Force (TF) per analizzare le cause della `non pulizia` di FTU e per identificare le nuove procedure da seguire per la pulizia della camera da vuoto. Le azioni che la TF intraprese furono: leak tests, monitoraggio continuo dello stato del vuoto e revisione critica del lavoro fatto precedentemente. Vennero poi analizzate delle misure fatte a suo tempo sui materiali presenti nella camera da vuoto di FTU e, nel caso delle termocoppie, si decise di ripetere il test. Da questa seconda prova emerse che i cilindretti di queste termocoppie sono delle riserve inesauribili di acqua che vengono alimentate da ogni riapertura della macchina. Il lavoro della TF si concluse con una serie di procedure e raccomandazioni, da seguire prima di ogni riapertura della macchina e durante le campagne sperimentali a macchina fredda; tali procedure tengono conto del fatto che negli anni e` aumentata la quantita` di materiali plastici presenti nella camera da vuoto, soprattutto nei ports. FTU sta attualmente operando in condizioni piu` accettabili di pulizia della camera.

    The small emplacement excavator (SEE) is a ruggedized military vehicle with backhoe and front loader used by the US Army for explosive ordinance disposal (EOD), combat engineer, and general utility excavation activities. In order to evaluate the feasibility of removing personnel from the vehicle during the high risk EOD excavation tasks a development and demonstration project was initiated to evaluate performance capabilities of the SEE under telerobotic control. This feasibility study was performed at the request of the Ordinance Missile and Munitions Center and School (OMMCS) at the Redstone Arsenal to help define requirements for further joint service development activities. Development of a telerobotic SEE (TSEE) was performed by the Oak Ridge National Laboratory (ORNL) in a project funded jointly by the US Army Project Manager for Ammunition Logistics (PM-AMMOLOG) and the Department of Energy (DOE) Office of Technology Development (OTD) Robotics Technology Development Program (RTDP). A technology demonstration of the TSEE was conducted at McKinley Range, Redstone Arsenal, Huntsville, Alabama, on September 13--17, 1993. The primary objective of the demonstration was to evaluate and demonstrate the feasibility of remote EOD. During the demonstration, approximately 40 EOD specialists were instructed on telerobotic operation of the TSEE and then were asked to complete a series of simulated EOD tasks. Upon completion of the tasks, participants completed an evaluation of the system including human factors performance data.

    A modern approach to relay co-ordination that takes advantage of the improved performance of modern protective relays and circuits was proposed. The proposed method dealt with a mixture of new and old equipment and was most useful when implemented using common spreadsheet software. The suggested approach justified reduced time margins for relay co-ordination in many difficult applications. Other established approaches were reviewed. A discussion of fixed and variable time margin allowances was presented. The formulation of an equation to determine the required upstream relay operating time was explained, with sample calculations. Relay performance standards and modern protective equipment were discussed. It was concluded that modern relays and circuit breakers are much more advanced than designs of the recent past. The method described allowed significant reductions in margins which enabled modern relays to operate faster. While calculations for the procedures were said to be tedious to perform by hand, they can be easily done with spreadsheet software. 10 refs., 4 figs.

    Can CSR theory, in conjunction with a recently proposed globally calibrated CSR ordination ("StrateFy"), using only three easily measured leaf traits (leaf area, specific leaf area and leaf dry matter content) predict the functional signature of herbaceous vegetation along experimentally manipulated gradients of soil fertility and disturbance? To determine this, we grew 37 herbaceous species in mixture for five years in 24 experimental mesocosms differing in factorial levels of soil resources (stress) and density-independent mortality (disturbance). We measured 16 different functional traits and then ordinated the resulting vegetation within the CSR triangle using StrateFy. We then calculated community-weighted mean (CWM) values of the competitor (CCWM), stress-tolerator (SCWM) and ruderal (RCWM) scores for each mesocosm. We found a significant increase in SCWM from low to high stress mesocosms, and an increase in RCWM from lowly to highly disturbed mesocosms. However, CCWM did not decline significantly as intensity of stress or disturbance increased, as predicted by CSR theory. This last result likely arose because our herbaceous species were relatively poor competitors in global comparisons and thus no strong competitors in our species pool were selectively favoured in low stress and low disturbed mesocosms. Variation in the 13 other traits, not used by StrateFy, largely argeed with the predictions of CSR theory. StrateFy worked surprisingly well in our experimental study except for the C-dimension. Despite loss of some precision, it has great potential applicability in future studies due to its simplicity and generality.

    Predictive classifications of life histories are essential for evolutionary ecology. While attempts to apply a single approach to all organisms may be overambitious, recent advances suggest that more narrow ordination schemes can be useful. However, these schemes mostly lack easily observable proxies of the position of a species on respective axes. It has been proposed that, in insects, the degree of capital (vs. income) breeding, reflecting the importance of adult feeding for reproduction, correlates with various ecological traits at the level of among-species comparison. We sought to prove these ideas via rigorous phylogenetic comparative analyses. We used experimentally derived life-history data for 57 species of European Geometridae (Lepidoptera), and an original phylogenetic reconstruction. The degree of capital breeding was estimated based on morphological proxies, including relative abdomen size of females. Applying Brownian-motion-based comparative analyses (with an original update to include error estimates), we demonstrated the associations between the degree of capital breeding and larval diet breadth, sexual size dimorphism, and reproductive season. Ornstein-Uhlenbeck model based phylogenetic analysis suggested a causal relationship between the degree of capital breeding and diet breadth. Our study indicates that the gradation from capital to income breeding is an informative axis to ordinate life-history strategies in flying insects which are affected by the fecundity vs. mobility trade off, with the availability of easy to record proxies contributing to its predictive power in practical contexts. © 2016 by the Ecological Society of America.

    Full Text Available The Municipality of Lingayen being the capital town of the Province of Pangasinan is an attractive site not only because of its rich history but the present tourism and trading condition that makes it more welcoming. As the municipality becomes a better place to live and to invest, increase of population is an inevitable phenomenon that needs legislative and administrative measures in order to have less negative consequences in the future. The Municipal Zoning Ordinance and the Comprehensive Land Use Plan are the two important documents in this research. These are guides in the construction of survey instrument. This research looked into the provisions that make concerned local offices responsible in implementing and monitoring the priority projects. It was conducted in the Municipality of Lingayen from January to April 2014. It found out that all the provisions stated in the Municipal Zoning Ordinance were observed and the priority projects of the municipality are in on-going status. It is recommended that there should be monitoring and assessment activities to be done in order to remind those in-charge of the projects to finish them according to plan. Also, partnership with private enterprises and other local government units should be strengthened in order to implement the priority projects.

    Full Text Available ARES is a multidimensional parallel discrete ordinates particle transport code with arbitrary order anisotropic scattering. It can be applied to a wide variety of radiation shielding calculations and reactor physics analysis. ARES uses state-of-the-art solution methods to obtain accurate solutions to the linear Boltzmann transport equation. A multigroup discretization is applied in energy. The code allows multiple spatial discretization schemes and solution methodologies. ARES currently provides diamond difference with or without linear-zero flux fixup, theta weighted, directional theta weighted, exponential directional weighted, and linear discontinuous finite element spatial differencing schemes. Discrete ordinates differencing in angle and spherical harmonics expansion of the scattering source are adopted. First collision source method is used to eliminate or mitigate the ray effects. Traditional source iteration and Krylov iterative method preconditioned with diffusion synthetic acceleration are applied to solve the linear system of equations. ARES uses the Koch-Baker-Alcouffe parallel sweep algorithm to obtain high parallel efficiency. Verification and validation for the ARES transport code system have been done by lots of benchmarks. In this paper, ARES solutions to the HBR-2 benchmark and C5G7 benchmarks are in excellent agreement with published results. Numerical results are presented which demonstrate the accuracy and efficiency of these methods.

    TRIDENT solves the two-dimensional-multigroup-transport equations in rectangular (x-y) and cylindrical (r-z) geometries using a regular triangular mesh. Regular and adjoint, inhomogeneous and homogeneous (k/sub eff/ and eigenvalue searches) problems subject to vacuum, reflective, white, or source boundary conditions are solved. General anisotropic scattering is allowed and anisotropic-distributed sources are permitted. The discrete-ordinates approximation is used for the neutron directional variables. An option is included to append a fictitious source to the discrete-ordinates equations that is defined such that spherical-harmonics solutions (in x-y geometry) or spherical-harmonics-like solutions (in r-z geometry) are obtained. A spatial-finite-element method is used in which the angular flux is expressed as a linear polynomial in each triangle that is discontinous at triangle boundaries. Unusual Features of the program: Provision is made for creation of standard interface output files for S/sub N/ constants, angle-integrated (scalar) fluxes, and angular fluxes. Standard interface input files for S/sub N/ constants, inhomogeneous sources, cross sections, and the scalar flux may be read. Flexible edit options as well as a dump and restart capability are provided

  7. Assessing Heterogeneity for Factor Analysis Model with Continuous and Ordinal Outcomes

    2016-01-01

    Full Text Available Factor analysis models with continuous and ordinal responses are a useful tool for assessing relations between the latent variables and mixed observed responses. These models have been successfully applied to many different fields, including behavioral, educational, and social-psychological sciences. However, within the Bayesian analysis framework, most developments are constrained within parametric families, of which the particular distributions are specified for the parameters of interest. This leads to difficulty in dealing with outliers and/or distribution deviations. In this paper, we propose a Bayesian semiparametric modeling for factor analysis model with continuous and ordinal variables. A truncated stick-breaking prior is used to model the distributions of the intercept and/or covariance structural parameters. Bayesian posterior analysis is carried out through the simulation-based method. Blocked Gibbs sampler is implemented to draw observations from the complicated posterior. For model selection, the logarithm of pseudomarginal likelihood is developed to compare the competing models. Empirical results are presented to illustrate the application of the methodology.

    Graphics Processing Unit (GPU), originally developed for real-time, high-definition 3D graphics in computer games, now provides great faculty in solving scientific applications. The basis of particle transport simulation is the time-dependent, multi-group, inhomogeneous Boltzmann transport equation. The numerical solution to the Boltzmann equation involves the discrete ordinates (S n ) method and the procedure of source iteration. In this paper, we present a GPU accelerated simulation of one energy group time-independent deterministic discrete ordinates particle transport in 3D Cartesian geometry (Sweep3D). The performance of the GPU simulations are reported with the simulations of vacuum boundary condition. The discussion of the relative advantages and disadvantages of the GPU implementation, the simulation on multi GPUs, the programming effort and code portability are also reported. The results show that the overall performance speedup of one NVIDIA Tesla M2050 GPU ranges from 2.56 compared with one Intel Xeon X5670 chip to 8.14 compared with one Intel Core Q6600 chip for no flux fixup. The simulation with flux fixup on one M2050 is 1.23 times faster than on one X5670.

    2009-03-01

    Ordinal measures are frequently encountered in travel behavior research. This paper presents a new method for combining them when a hierarchical structure of the data can be presumed. This method is applied to study the subjective assessment of the amount of travel by different transportation modes among a group of French clerical workers, along with the desire to increase or decrease the use of such modes. Some advantages of this approach over traditional data reduction technique such as factor analysis when applied to ordinal data are then illustrated. In this study, combining evidence from several variables sheds light on the observed moderately negative relationship between the personal assessment of the amount of travel and the desire to increase or decrease it, thus integrating previous partial (univariate) results. We find a latent demand for travel, thus contributing to clarify the behavioral mechanisms behind the induced traffic phenomenon. Categorizing the above relationship by transportation mode shows a desire for a less environmental-friendly mix of modes (i.e. a greater desire to use heavy motorized modes and a lower desire to use two-wheeled modes), whenever the respondents do not feel to travel extensively. This result, combined with previous theoretical investigations concerning the determinants of the desire to alter trips consumption levels, shows the importance of making people aware of how much they travel.

Supermarket food prices were collected for 106 items using a University of Washington Center for Public Health Nutrition market basket at affected and unaffected supermarket chain stores at three times: March 2015 (1-month pre-policy enactment), May 2015 (1-month post-policy enactment) and May 2016 (1-year post-policy enactment). Food items were categorized into four food processing groups, from minimally to ultra-processed. Data were analysed across time using a multilevel, linear difference-in-differences model at the store and price level stratified by level of food processing. Six large supermarket chain stores located in Seattle ('intervention') affected by the policy and six same-chain but unaffected stores in King County ('control'), Washington, USA. One hundred and six food and beverage items. The largest change in average price by food item was +$US 0·53 for 'processed foods' in King County between 1-month post-policy and 1-year post-policy enactment (P minimum wage ordinance by level of the food's processing. These results suggest that the early implementation of a city-level minimum wage policy does not alter supermarket food prices by level of food processing.

    To determine whether vital signs in patients suffering from acute pain in the out-of-hospital setting have any association with pain severity measured using an ordinal pain scale. We conducted a retrospective analysis of over 53 000 adult patients aged between 16 and 100 years, who presented to paramedics complaining of acute pain between 1 January 2004 and 30 November 2006. Simple correlation (Spearman's) and ordinal logistic regression techniques were used to create a proportional odds model to explore the relationship between patient-reported pain score and initial vital signs including respiratory rate, pulse rate and blood pressure. There was a weak but significant correlation between respiratory rate and initial pain score (R=0.15, Plogistic regression. In adults, a respiratory rate of 25 breaths/min or more was the most important predictor of having more severe pain. Tachycardia and systolic hypertension may also be important in younger and older patients, respectively. Simple correlation fails to show clinically important associations between prehospital vital signs and pain severity.

    For children ages 1-14, 21.6% of drowning cases involve swimming, wading, or playing in natural bodies of water, such as rivers and lakes. Personal flotation devices (PFDs) are believed to be an effective prevention measure. We measure compliance with city and county ordinances, publicized but not actively enforced, requiring that PFDs be worn by children accessing public bodies of water in Sacramento County, California. During June-August 2010, volunteers conducted 79 observation sessions at three popular local river beaches where PFDs were available for use at no cost. They recorded personal characteristics and PFD use for 1,727 children in or very near the water and believed to be 0-13 years of age (the age covered by the ordinances). We used logistic regression to quantify differences in use by subject characteristics and study site. The prevalence of PFD use was 29.9% overall, with large and significant differences by age: Usage did not vary significantly by sex or race/ethnicity, and was somewhat higher at one study site (33.1%) than at the others (25.9% and 27.3%), P = 0.009. The combination of a statutory requirement and a cost-elimination strategy was associated with moderate rates of PFD use that were highest among young children.

    Highlights: • Two-dimensional discrete ordinates neutron transport. • Analytical Discrete Ordinates (ADO) nodal method. • Heterogeneous media fixed source problems. • Local solutions. - Abstract: In this work, recent results on the solution of fixed-source two-dimensional transport problems, in Cartesian geometry, are reported. Homogeneous and heterogeneous media problems are considered in order to incorporate the idea of arbitrary number of domain division into regions (nodes) when applying the ADO method, which is a method of analytical features, to those problems. The ADO-nodal formulation is developed, for each node, following previous work devoted to heterogeneous media problem. Here, however, the numerical procedure is extended to higher number of domain divisions. Such extension leads, in some cases, to the use of an iterative method for solving the general linear system which defines the arbitrary constants of the general solution. In addition to solve alternative heterogeneous media configurations than reported in previous works, the present approach allows comparisons with results provided by other metodologies generated with refined meshes. Numerical results indicate the ADO solution may achieve a prescribed accuracy using coarser meshes than other schemes.

  14. A voice from the margins: Investigating the African Adventist rationale on the quest for female ordination

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Discussions surrounding women�s ordination reached a peak with the 60th General Conference Session (GCS 2015 of the Seventh-day Adventist (SDA Church. A report compiled by a section of delegates from the East-Central Africa Division � Biblical Research Committee indicated that this continent was not yet ready to ordain women as pastors. In light of the report, this article aims to investigate the rationale of such a stark decision. Firstly, the report shows that African Adventist women theologians were omitted from the discussions � a lack of good will from the church leadership towards the females as the majority of the membership. Secondly, the decision against ordination of women is suspect and biblically inconclusive. Through an overview of literature on a biblical missional design, the article postulates: Contextualisation and theologising are necessary for Africa, but the SDA Church must remember that globally both theology and culture are subject to the biblical guidelines, and thus to God�s missio Dei as well.Intradisciplinary and/or interdisciplinary implications: This article balances cultural contextualism and gender relations � challenging a cultural bias through a missional hermeneutic.

    Full Text Available Abstract Background A number of potential therapeutic approaches for neurological disorders have failed to provide convincing evidence of efficacy, prompting pharmaceutical and health companies to discontinue their involvement in drug development. Limitations in the statistical analysis of complex endpoints have very likely had a negative impact on the translational process. Methods We propose a transitional ordinal model with an autoregressive component to overcome previous limitations in the analysis of Upper Extremity Motor Scores, a relevant endpoint in the field of Spinal Cord Injury. Statistical power and clinical interpretation of estimated treatment effects of the proposed model were compared to routinely employed approaches in a large simulation study of two-arm randomized clinical trials. A revisitation of a key historical trial provides further comparison between the different analysis approaches. Results The proposed model outperformed all other approaches in virtually all simulation settings, achieving on average 14 % higher statistical power than the respective second-best performing approach (range: -1 %, +34 %. Only the transitional model allows treatment effect estimates to be interpreted as conditional odds ratios, providing clear interpretation and visualization. Conclusion The proposed model takes into account the complex ordinal nature of the endpoint under investigation and explicitly accounts for relevant prognostic factors such as lesion level and baseline information. Superior statistical power, combined with clear clinical interpretation of estimated treatment effects and widespread availability in commercial software, are strong arguments for clinicians and trial scientists to adopt, and further extend, the proposed approach.

    1993-01-01

    In September 1991 the Co-ordinated Research Programme (CRP) on ''Operator Support Systems (OSSs) in Nuclear Power Plants'' was approved in the framework of the Project ''Man-Machine Interface Studies''. The main objective of the programme is to provide guidance and technology transfer in the development and implementation of OSSs. This includes the experience with man-machine interfaces and closely related issues such as control and instrumentation, the use of computers, and operator qualification. The first Co-ordinated Research Meeting held in Vienna, 13-16 October 1992, prepared a summary report which defined the tasks and the responsibilities of the CRP participants. A time schedule and future actions were also agreed upon at this meeting. The second meeting was held in Budapest, Hungary, from 5 to 8 October 1993 and was sponsored by the KFKI Atomic Energy Research Institute. The meeting reviewed the progress of the tasks defined by the first meeting, considered reports on national activities in the subject area, and agreed on time schedule and future actions. The present volume contains: (1) report prepared by the CRP meeting, (2) reports presented by the national delegates, and (3) CRP background and working plan. Refs, figs and tabs

    2014-08-01

    A simple thermo-physiological model of outdoor thermal sensation adjusted with psychological factors is developed aiming to predict thermal sensation in Mediterranean climates. Microclimatic measurements simultaneously with interviews on personal and psychological conditions were carried out in a square, a street canyon and a coastal location of the greater urban area of Athens, Greece. Multiple linear and ordinal regression were applied in order to estimate thermal sensation making allowance for all the recorded parameters or specific, empirically selected, subsets producing so-called extensive and empirical models, respectively. Meteorological, thermo-physiological and overall models - considering psychological factors as well - were developed. Predictions were improved when personal and psychological factors were taken into account as compared to meteorological models. The model based on ordinal regression reproduced extreme values of thermal sensation vote more adequately than the linear regression one, while the empirical model produced satisfactory results in relation to the extensive model. The effects of adaptation and expectation on thermal sensation vote were introduced in the models by means of the exposure time, season and preference related to air temperature and irradiation. The assessment of thermal sensation could be a useful criterion in decision making regarding public health, outdoor spaces planning and tourism.

  18. Energy dependent mesh adaptivity of discontinuous isogeometric discrete ordinate methods with dual weighted residual error estimators

    In this paper a hanging-node, discontinuous Galerkin, isogeometric discretisation of the multigroup, discrete ordinates (SN) equations is presented in which each energy group has its own mesh. The equations are discretised using Non-Uniform Rational B-Splines (NURBS), which allows the coarsest mesh to exactly represent the geometry for a wide range of engineering problems of interest; this would not be the case using straight-sided finite elements. Information is transferred between meshes via the construction of a supermesh. This is a non-trivial task for two arbitrary meshes, but is significantly simplified here by deriving every mesh from a common coarsest initial mesh. In order to take full advantage of this flexible discretisation, goal-based error estimators are derived for the multigroup, discrete ordinates equations with both fixed (extraneous) and fission sources, and these estimators are used to drive an adaptive mesh refinement (AMR) procedure. The method is applied to a variety of test cases for both fixed and fission source problems. The error estimators are found to be extremely accurate for linear NURBS discretisations, with degraded performance for quadratic discretisations owing to a reduction in relative accuracy of the "exact" adjoint solution required to calculate the estimators. Nevertheless, the method seems to produce optimal meshes in the AMR process for both linear and quadratic discretisations, and is ≈×100 more accurate than uniform refinement for the same amount of computational effort for a 67 group deep penetration shielding problem.

  19. Co-ordinate regulation of genes involved in storage lipid mobilization in Arabidopsis thaliana.

    Molecular genetic approaches in the model plant Arabidopsis thaliana (Col0) are shedding new light on the role and control of the pathways associated with the mobilization of lipid reserves during oilseed germination and post-germinative growth. Numerous independent studies have reported on the expression of individual genes encoding enzymes from the three major pathways: beta-oxidation, the glyoxylate cycle and gluconeogenesis. However, a single comprehensive study of representative genes and enzymes from the different pathways in a single plant species has not been done. Here we present results from Arabidopsis that demonstrate the co-ordinate regulation of gene expression and enzyme activities for the acyl-CoA oxidase- and 3-ketoacyl-CoA thiolase-mediated steps of beta-oxidation, the isocitrate lyase and malate synthase steps of the glyoxylate cycle and the phosphoenolpyruvate carboxykinase step of gluconeogenesis. The mRNA abundance and enzyme activities increase to a peak at stage 2, 48 h after the onset of seed germination, and decline thereafter either to undetectable levels (for malate synthase and isocitrate lyase) or low basal levels (for the genes of beta-oxidation and gluconeogenesis). The co-ordinate induction of all these genes at the onset of germination raises the possibility that a global regulatory mechanism operates to induce the expression of genes associated with the mobilization of storage reserves during the heterotrophic growth period.

    A numerical accuracy analysis of the radiative transfer equation (RTE) solution based on separation of the diffuse light field into anisotropic and smooth parts is presented. The analysis uses three different algorithms based on the discrete ordinate method (DOM). Two methods, DOMAS and DOM2+, that do not use the truncation of the phase function, are compared against the TMS-method. DOMAS and DOM2+ use the Small-Angle Modification of RTE and the single scattering term, respectively, as an anisotropic part. The TMS method uses Delta-M method for truncation of the phase function along with the single scattering correction. For reference, a standard discrete ordinate method, DOM, is also included in analysis. The obtained results for cases with high scattering anisotropy show that at low number of streams (16, 32) only DOMAS provides an accurate solution in the aureole area. Outside of the aureole, the convergence and accuracy of DOMAS, and TMS is found to be approximately similar: DOMAS was found more accurate in cases with coarse aerosol and liquid water cloud models, except low optical depth, while the TMS showed better results in case of ice cloud.

  1. Efficient nonlinear registration of 3D images using high order co-ordinate transfer functions.

    Barber, D C

    1999-01-01

    There is an increasing interest in image registration for a variety of medical imaging applications. Image registration is achieved through the use of a co-ordinate transfer function (CTF) which maps voxels in one image to voxels in the other image, including in the general case changes in mapped voxel intensity. If images of the same subject are to be registered the co-ordinate transfer function needs to implement a spatial transformation consisting of a displacement and a rigid rotation. In order to achieve registration a common approach is to choose a suitable quality-of-registration measure and devise a method for the efficient generation of the parameters of the CTF which minimize this measure. For registration of images from different subjects more complex transforms are required. In general function minimization is too slow to allow the use of CTFs with more than a small number of parameters. However, provided the images are from the same modality and the CTF can be expanded in terms of an appropriate set of basis functions this paper will show how relatively complex CTFs can be used for registration. The use of increasingly complex CTFs to minimize the within group standard deviation of a set of normal single photon emission tomography brain images is used to demonstrate the improved registration of images from different subjects using CTFs of increasing complexity.

    1989-01-01

    This Co-ordinated Research Programme (CRP) was formally established by the Agency in October 1988, and has since then expanded to encompass 13 participants in 13 countries. Its general objective is to help establish competence in the use of stable isotope techniques, particularly in developing countries, and particularly with reference to applications of 2 H, 13 C, 15 N, and 18 O. This report summarizes the discussions that took place during the first Research Co-ordination Meeting (RCM). Working papers (progress reports) presented by the participants are included as annexes together with a preliminary report on the results of a series of intercomparison exercises involving enriched stable isotope reference materials containing 2 H, 13 C, 15 N and 18 O. For the future it was agreed that more work needs to be done to harmonize the analytical techniques being used, and to obtain support for new CRPs relating to human energy expenditure studies in pregnancy, lactation, growth and other conditions, and to studies of nitrogen turnover in relation to malnutrition and liver function.

    Full Text Available In his early dialogue ‘On order’ (De ordine Augustine dramatises a discussion of theodicy in which the Manichaean solution is clearly rejected, even though the debate ends in aporia. It is argued in this paper that the dialogue’s dramatic setting at the villa in Cassiciacum is strongly reminiscent of Manichaean imagery and the stock motifs of the Manichaean mythological system. It is proposed in the dialogue itself, that the scenic elements (Augustine’s ill health, night and darkness, the dawning day, dirt and ugliness, fighting cocks have the character of signs which illustrate the significance of the not-beautiful and the negative in the divine order. The dialogue setting thus presents an ontological scale that leads from the levels of reduced being up to the highest being, linking night or darkness to light or day, dirt to purity, sickness to health, defeat to victory, the ugly to the beautiful. The dialogue setting becomes a semiotic system in which even the ontologically deficient forms of phenomenon always also refer to something at the highest level, namely the omnipotent divine creator. The scenic design of De ordine can thus be read as an extension of the Manichaean system of codes, and hence as a message also addressed to a Manichaean readership.

    1990-01-01

    This Co-ordinated Research Programme (CRP) was started by the Agency in 1985, within the framework of the Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology in the Asia and Pacific Region (RCA). Its main purpose has been to obtain comparative data on existing elemental concentrations of potentially toxic elements in foodstuffs in various Asian countries. The elements to be studied include the potentially most toxic trace elements (As, Cd, Hg, Pb, Se) as well as others of relevance to national monitoring programmes, such as Br, Cr, Cu, Fe, I, Mn, Sb, Tl, and Zn. An important supplementary purpose of the programme is to help establish analytical expertise for work of this kind in the individual countries. Scientists from several RCA Member States have participated in it, namely from Australia, Bangladesh, China, India, Indonesia, Japan, Malaysia, Pakistan, Thailand, and also from institutes in several countries outside the region, i.e., Argentina, Brazil, Jamaica and The Netherlands. This report summarizes the discussions that took place during the third and final Research Co-ordination Meeting (RCM) for the programme from 20-24 November 1989, in Jakarta, Indonesia. This document includes the progress reports presented by the participants as well as discussions and conclusions drawn from the meeting

  6. Copying you copying me: interpersonal motor co-ordination influences automatic imitation.

    Daniel Joel Shaw

    Full Text Available Moving in a co-ordinated fashion with another individual changes our behaviour towards them; we tend to like them more, find them more attractive, and are more willing to co-operate with them. It is generally assumed that this effect on behaviour results from alterations in representations of self and others. Specifically, through neurophysiological perception-action matching mechanisms, interpersonal motor co-ordination (IMC is believed to forge a neural coupling between actor and observer, which serves to blur boundaries in conceptual self-other representations and causes positive views of the self to be projected onto others. An investigation into this potential neural mechanism is lacking, however. Moreover, the specific components of IMC that might influence this mechanism have not yet been specified. In the present study we exploited a robust behavioural phenomenon--automatic imitation--to assess the degree to which IMC influences neural action observation-execution matching mechanisms. This revealed that automatic imitation is reduced when the actions of another individual are perceived to be synchronised in time, but are spatially incongruent, with our own. We interpret our findings as evidence that IMC does indeed exert an effect on neural perception-action matching mechanisms, but this serves to promote better self-other distinction. Our findings demonstrate that further investigation is required to understand the complex relationship between neural perception-action coupling, conceptual self-other representations, and social behaviour.

  8. Co-ordinated research programme on development and application of isotopic techniques in studies of vitamin A nutrition. Report of the first research co-ordination meeting

    International Nuclear Information System (INIS)

    1997-01-01

    In Vitamin A nutrition, evaluations to ascertain the efficacy of intervention strategies are becoming increasingly important. However, state-of-the-art methods for evaluating vitamin A status often do not provide enough quantitative information on vitamin A status and the bioconversion of carotenoids, particularly in people with subclinical vitamin A deficiency. These limitations have had programmatic consequences. The principal reason the new Coordinated Research programme (CRP) was formulated was to improve techniques for measuring vitamin A status and the bioconversion of carotenoids to vitamin A with the expectation that the new methods could contribute meaningfully to field-based evaluations of the efficacy of intervention strategies. The International Atomic Energy Agency (IAEA) is sponsoring programmes to develop and transfer isotopic techniques to improve nutrition monitoring in developing countries. The New CRP ''Development and Application of Isotopic Techniques in Studies of Vitamin A Nutrition'' has seven teams, six of which are working to develop methods based on orally administered isotopically labelled retinol which will be a valid measure of whole body retinol (mostly hepatic reserves) and useful under typical field conditions, particularly in women and children with marginal vitamin A deficiency. The seventh team is biosynthesizing uniformly deuterated β-carotene by growing foods in deuterated water. This report summarizes the research to be undertaken, as presented at the first Research Co-ordination Meeting

    1999-01-01

    The concept for the Co-ordinated Research Programme on isotopic evaluations of maternal and child nutrition to help prevent stunting was a consequence of discussions held between IAEA staff and participants in a regional training course on 'Isotope Techniques in Human Nutrition' held in Lima, Peru in June 1996. The intention then was to develop research on factors influencing the success of lactation and the consequent effects on the breast-fed child. The project would have Latin American participants to promote regional exchange of expertise and ideas. Initial participation was from Argentina, Chile, Mexico, Peru and Venezuela. Brazil and Pakistan have now been added to these. There are three Specific Research Objectives: (1) To develop stable isotope methods for measuring breast-milk intake using regionally available equipment. (2) To apply the methodology in the assessment of milk intake in infants in relation to maternal nutrition, socio-economic status and education, and infant nutrition and intake of macro- and micro-nutrients. (3) To use information gathered at 2) to determine the need for supplementation programmes for mothers and/or infants, and educational programmes for the mothers

    Full Text Available Il cineturismo rappresenta un fenomeno socio-culturale recente e in forte diffusione in Italia. Il suo legame con la valorizzazione del territorio è inscindibile dal momento in cui lo spettatore sceglie un determinato luogo da visitare, stimolato dalla visione di un film, di una fiction o di un cortometraggio. La valorizzazione del territorio attraverso il cinema non è automatica. Vi sono luoghi che grazie a dei film di successo hanno riscontrato un afflusso esponenziale di turisti e altri luoghi dove questo non è avvenuto. Predisporre spazi per l'accoglienza di produzioni cinematografiche o finanziare le produzioni cinematografiche in uno specifico territorio consente un maggiore interesse, da parte dei registi, nei confronti di quelle location che di quel territorio fanno parte.  The film tourism is a socio-cultural phenomenon recently and rapidly spread in Italy. His connection with the development of the area is inseparable from the moment when the viewer chooses a certain place to visit, stimulated by watching a movie, a drama or a short film. The development of the area through cinema is not automatic. There are places that thanks to the hit movie found an exponential influx of tourists and other places where this has not happened. Provide space for the reception of film productions or finance film productions in a specific area allows a greater interest on the part of directors, in respect of those locations that are part of that territory.

    In most of the discrete ordinate schemes (DOS) reported in the literature, the discrete directions are fixed, and unable to be arbitrarily adjusted; therefore, it is difficult to employ these schemes to calculate the radiative energy image-formation of pulverized-coal furnaces. On the basis of a new DOS, named the discrete ordinate scheme with (an) infinitely small weight(s), which was recently proposed by the authors, a novel algorithm for computing the pinhole image-formation process is developed in this work. The performance of this algorithm is tested, and is found to be also suitable for parallel computation

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

    Full Text Available Osteoporosis is a disorder of bone re-modeling, characterized by loss of its micro-architecture and decreased bone density, which lead to fragility and high risk of fracture following moderate traumata. Osteoporosisrelated pathological fractures occur more frequently in post-menopausal women, and the WHO estimates that the risk of osteoporotic fractures in women is approximately 40% during lifetime. The prevention of these osteoporotic fractures is considered one of the primary objectives for the control of the economical health burden of modern societies. The first part of this paper briefly outlines the physio-pathological basis, the epidemiology, the diagnosis and the available treatment options for osteoporosis, with particular regard to those therapies that are able to reduce the incidence of pathological fractures, that represent the main cost factor of the disease. In the second part, we reviewed the economical evaluations published on the cost of illness and of the costefficacy of the treatments. The studies that have analyzed the cost of osteoporosis, although incompletely, highlight that the greatest expenditures are related to hospitalization and rehabilitation after hip fracture, while the cost for the pharmacological treatment is relatively low. The cost-efficacy and cost-utility analyses conducted on pharmacological treatment are quite heterogeneous, and therefore hardly comparable, beside being conducted in countries with different health systems; the obtained data are nor directly transferable to the Italian setting. However, it emerges that diphosphonates, estrogens and SERMs (selective estrogen receptor modulators are among the drugs with more favorable cost/effectiveness ratio, but there is still an uncertainty in the detection of the appropriate patient groups, which is crucial for the clinical, economical and ethical optimization of prevention interventions.

    The problem for establishing noninferiority is discussed between a new treatment and a standard (control) treatment with ordinal categorical data. A measure of treatment effect is used and a method of specifying noninferiority margin for the measure is provided. Two Z-type test statistics are proposed where the estimation of variance is constructed under the shifted null hypothesis using U-statistics. Furthermore, the confidence interval and the sample size formula are given based on the proposed test statistics. The proposed procedure is applied to a dataset from a clinical trial. A simulation study is conducted to compare the performance of the proposed test statistics with that of the existing ones, and the results show that the proposed test statistics are better in terms of the deviation from nominal level and the power.

    2000-01-01

    The CRP's focus is on the preparation of site-specific radiopharmaceuticals labelled with with β - emitters for the treatment of cancer. The radiopharmaceuticals should be designed in such a way to deliver the therapeutic doses with high specificity to tumour sites and with minimum dose to other organs. The 2nd Research Co-ordination Meeting (RCM) took place in Mumbai, India from 31 January to 4 February 2000. The present report includes the results of all the participants including the report of the participant from Pakistan who could not attend the meeting. During the second RCM, three main aspects were dealt with viz. the different therapeutic isotopes studied, different carrier molecules like peptides and antibody and the biological aspects of these preparations

    The integral form of the discrete ordinates equations involves a system of equations that has a large, dense coefficient matrix. The serial construction methodology is presented and properties that affect the execution times to construct and solve the system are evaluated. Two approaches for massively parallel implementation of the solution algorithm are proposed and the current results of one of these are presented. The system of equations May be solved using two parallel solvers-block Jacobi and conjugate gradient. Results indicate that both methods can reduce overall wall-clock time for execution. The conjugate gradient solver exhibits better performance to compete with the traditional source iteration technique in terms of execution time and scalability. The parallel conjugate gradient method is synchronous, hence it does not increase the number of iterations for convergence compared to serial execution, and the efficiency of the algorithm demonstrates an apparent asymptotic decline.

  5. Boltzmann-Fokker-Planck calculations using standard discrete-ordinates codes

    1987-01-01

    The Boltzmann-Fokker-Planck (BFP) equation can be used to describe both neutral and charged-particle transport. Over the past several years, the author and several collaborators have developed methods for representing Fokker-Planck operators with standard multigroup-Legendre cross-section data. When these data are input to a standard S/sub n/ code such as ONETRAN, the code actually solves the Boltzmann-Fokker-Planck equation rather than the Boltzmann equation. This is achieved wihout any modification to the S/sub n/ codes. Because BFP calculations can be more demanding from a numerical viewpoint than standard neutronics calculations, we have found it useful to implement new quadrature methods ad convergence acceleration methods in the standard discrete-ordinates code, ONETRAN. We discuss our BFP cross-section representation techniques, our improved quadrature and acceleration techniques, and present results from BFP coupled electron-photon transport calculations performed with ONETRAN. 19 refs., 7 figs

    The main objective of the study was to examine the present degree of compliance with the Energy Consumption Labelling Ordinance for large household appliances in Germany in an empirical inventory. Concrete proposals to improve the degree of compliance with Directive among manufacturers and retailers were to be elaborated based on this inventory and the analysis of possible deficiencies in implementation and and their causes. A further objective of the study was to examine whether there was an increase in the share of appliance sales in the highest efficiency classes, so as to be able to judge the success of the measures provided in the Directive in accordance with the underlying energy and environmental objective of further reducing energy consumption in households. Furthermore, experience of other European countries in implementing the EU Directive was to be considered. (orig./CB)

    Numerical formulations and programming algorithms are given for the THREETRAN computer program which solves the discrete ordinates, multigroup transport equation in (x,y,z) geometry. An efficient, flexible, and general data-handling strategy is derived to make use of three hierarchies of storage: small core memory, large core memory, and disk file. Data management, input instructions, and sample problem output are described. A six-group, S 4 , 18 502 mesh point, 2 800 zone, k/sub eff/ calculation of the ZPPR-4 critical assembly required 144 min of CDC-7600 time to execute to a convergence tolerance of 5 x 10 -4 and gave results in good qualitative agreement with experiment and other calculations. 6 references

    Logistic random effects models are a popular tool to analyze multilevel also called hierarchical data with a binary or ordinal outcome. Here, we aim to compare different statistical software implementations of these models. We used individual patient data from 8509 patients in 231 centers with moderate and severe Traumatic Brain Injury (TBI) enrolled in eight Randomized Controlled Trials (RCTs) and three observational studies. We fitted logistic random effects regression models with the 5-point Glasgow Outcome Scale (GOS) as outcome, both dichotomized as well as ordinal, with center and/or trial as random effects, and as covariates age, motor score, pupil reactivity or trial. We then compared the implementations of frequentist and Bayesian methods to estimate the fixed and random effects. Frequentist approaches included R (lme4), Stata (GLLAMM), SAS (GLIMMIX and NLMIXED), MLwiN ([R]IGLS) and MIXOR, Bayesian approaches included WinBUGS, MLwiN (MCMC), R package MCMCglmm and SAS experimental procedure MCMC.Three data sets (the full data set and two sub-datasets) were analysed using basically two logistic random effects models with either one random effect for the center or two random effects for center and trial. For the ordinal outcome in the full data set also a proportional odds model with a random center effect was fitted. The packages gave similar parameter estimates for both the fixed and random effects and for the binary (and ordinal) models for the main study and when based on a relatively large number of level-1 (patient level) data compared to the number of level-2 (hospital level) data. However, when based on relatively sparse data set, i.e. when the numbers of level-1 and level-2 data units were about the same, the frequentist and Bayesian approaches showed somewhat different results. The software implementations differ considerably in flexibility, computation time, and usability. There are also differences in the availability of additional tools for model

  10. A massively parallel discrete ordinates response matrix method for neutron transport

    Hanebutte, U.R.; Lewis, E.E.

    1992-01-01

    In this paper a discrete ordinates response matrix method is formulated with anisotropic scattering for the solution of neutron transport problems on massively parallel computers. The response matrix formulation eliminates iteration on the scattering source. The nodal matrices that result from the diamond-differenced equations are utilized in a factored form that minimizes memory requirements and significantly reduces the number of arithmetic operations required per node. The red-black solution algorithm utilizes massive parallelism by assigning each spatial node to one or more processors. The algorithm is accelerated by a synthetic method in which the low-order diffusion equations are also solved by massively parallel red-black iterations. The method is implemented on a 16K Connection Machine-2, and S 8 and S 16 solutions are obtained for fixed-source benchmark problems in x-y geometry

    Shoot branching is a primary contributor to plant architecture, evolving independently in flowering plant sporophytes and moss gametophytes. Mechanistic understanding of branching is largely limited to flowering plants such as Arabidopsis, which have a recent evolutionary origin. We show that in gametophytic shoots of Physcomitrella, lateral branches arise by re-specification of epidermal cells into branch initials. A simple model co-ordinating the activity of leafy shoot tips can account for branching patterns, and three known and ancient hormonal regulators of sporophytic branching interact to generate the branching pattern- auxin, cytokinin and strigolactone. The mode of auxin transport required in branch patterning is a key divergence point from known sporophytic pathways. Although PIN-mediated basipetal auxin transport regulates branching patterns in flowering plants, this is not so in Physcomitrella, where bi-directional transport is required to generate realistic branching patterns. Experiments with callose synthesis inhibitors suggest plasmodesmal connectivity as a potential mechanism for transport.

    Psychopathy, while perhaps the earliest and most recognized personality disorder, is the subject of intense debate about its nature and measurement. The most recent proposal on its structural nature suggests that it is a multifaceted construct, made up of at least four dimensions reflecting Interpersonal, Affective, Lifestyle, and Antisocial anomalies (Hare & Neumann, 2005, 2006). These dimensions are significantly interrelated, suggesting that they are indicators for a super-ordinate factor. The nature of this higher-order factor may reflect the unifying feature which comprehensively defines the disorder. To examine this super-factor, the current study used several very large data sets of male (N = 4865) and female (N = 1099) offenders, and forensic psychiatric patients (N = 965), who were assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Structural equation modeling results indicated that the four first-order factor dimensions could be explained by a single second-order cohesive super-factor.

    Discrete ordinate theory was used to calculate the reflected and transmitted radiance of photons which have interacted with plane parallel maritime haze layers. The results are presented for three solar zenith angles, three values of the surface albedo, and a range of optical thicknesses from very thin to very thick. The diffuse flux at the lower boundary and the cloud albedo were tabulated. The forward peak and other features in the single scattered phase function caused the radiance in many cases to be very different from that for Rayleigh scattering. The variation of the radiance with both the zenith or nadir angle and the azimuthal angle is more marked, and the relative limb darkening under very thick layers is greater, for haze than for Rayleigh scattering. The downward diffuse flux at the lower boundary for A = O is always greater and the cloud albedo is always less for haze than for Rayleigh layers.

    In a hospital, a high proportion of working time occurs outside the traditional working day, affecting patient safety as staffing levels are at their lowest out of hours. A service evaluation audit was used to evaluate the effectiveness of a clinical out-of-hours nurse co-ordinator (COHNC) pilot role in a tertiary children's hospital. The COHNC role was trialled over a six-month period. During the pilot, the COHNC carried the junior paediatrician's 'bleep' and prioritised all phone calls and tasks. Following a patient assessment, the COHNC either performed the investigations and treatments within their scope of practice or escalated these to the appropriate multidisciplinary team member. A description of how the COHNC role has developed and its implications to nursing practice are presented in this article, along with an overview of the quantitative and qualitative data obtained during the audit.

    1998-11-01

    The aims of the Second Co-ordination Meting (RCM) of the Coordinated Research Programme (CRP) were to report on and review progress against the work programme set at the beginning of the CRP and to discuss the work plans for the second half of the programme. In many cases hydrogen is required to be measured in a bulk medium rather than merely at a surface. For this reason neutrons are used due to their high penetrating power in dense material. In addition, the mass attenuation coefficient for neutrons in hydrogen is significantly larger than for all other elements, meaning that neutrons have a higher probability of interacting with hydrogen than with other elements in the sample matrix. Neutrons have been used in the following areas: Fast Neutron Transmission, Scattering and Activation Technique; Digital Neutron Imaging; Hydrogen Detection by Epithermal Neutrons; Microscopic Behaviour of Hydrogen in Bulk Materials

    Full Text Available Tardigrades are important members of the Antarctic biota yet little is known about their role in the soil fauna or whether they are affected by anthropogenic factors. The German Federal Environment Agency commissioned research to assess the impact of human activities on soil meiofauna at 14 localities along the Antarctic peninsula during the 2009/2010 and 2010/2011 austral summers. We used ordination techniques to re-assess the block-sampling design used to compare areas of high and low human impact, to identify which of the sampled variables were biologically relevant and/or demonstrated an anthropogenic significance. We found the most significant differences between locations, reflecting local habitat and vegetation factor, rather than within-location anthropogenic impact. We noted no evidence of exotic imports but report on new maritime Antarctic sample sites and habitats.

    The co-ordinated Research and Environmental Surveillance Programme relevant to sea disposal of radioactive waste (CRESP) was created in 1981 in the framework of the 1977 Decision of the OECD Council establishing a Multilateral Consultation and Surveillance Mechanism for Sea Dumping of Radioactive Waste. CRESP was essentially a scientific research programme. Its main objective was to increase the knowledge of processes controlling the transfer of radionuclides in the marine environment, so that safety assessments could be based on more accurate and comprehensive scientific data. From 1986, in response to a request from the Paris Commission, CRESP also considered the scientific aspects of coastal releases. CRESP made it possible to co-ordinate national research activities and generated an important international co-operation in its areas of work. The vast amount of scientific information gathered in this framework increased strongly our knowledge of the impact of radionuclides introduced to the deep sea environment. In particular, CRESP provided the basis for a comprehensive safety analysis of sea dumping operations. This study, published by the NEA in 1985, is still e reference on the subject. In November 1993, the Sixteenth Consultative Meeting of Contracting Parties to the London Convention 1972 voted a total ban on the disposal at sea of radioactive wastes and other radioactive matter. Considering this decision, the conclusions of the 1985 safety analysis, and CRESP's view that new scientific findings are unlikely to alter these conclusions, the NEA Steering Committee for nuclear Energy decided in October 1995 to terminate the programme. The present report summarises the knowledge accumulated within CRESP over its fifteen years of existence. (author)

    The Dermatology Life Quality Index (DLQI) and the European Quality of Life-5 Dimension (EQ-5D) are separate measures that may be used to gather health-related quality of life (HRQoL) information from patients. The EQ-5D is a generic measure from which health utility estimates can be derived, whereas the DLQI is a specialty-specific measure to assess HRQoL. To reduce the burden of multiple measures being administered and to enable a more disease-specific calculation of health utility estimates, we explored an established mathematical technique known as ordinal logistic regression (OLR) to develop an appropriate model to map DLQI data to EQ-5D-based health utility estimates. Retrospective data from 4010 patients were randomly divided five times into two groups for the derivation and testing of the mapping model. Split-half cross-validation was utilized resulting in a total of ten ordinal logistic regression models for each of the five EQ-5D dimensions against age, sex, and all ten items of the DLQI. Using Monte Carlo simulation, predicted health utility estimates were derived and compared against those observed. This method was repeated for both OLR and a previously tested mapping methodology based on linear regression. The model was shown to be highly predictive and its repeated fitting demonstrated a stable model using OLR as well as linear regression. The mean differences between OLR-predicted health utility estimates and observed health utility estimates ranged from 0.0024 to 0.0239 across the ten modeling exercises, with an average overall difference of 0.0120 (a 1.6% underestimate, not of clinical importance). This modeling framework developed in this study will enable researchers to calculate EQ-5D health utility estimates from a specialty-specific study population, reducing patient and economic burden.

    The DANTSYS discrete ordinates computer code system is applied to quantitative estimation of water kerma rate distributions in the vicinity of discrete photon sources with energies in the 20- to 800-keV range in two-dimensional cylindrical r-z geometry. Unencapsulated sources immersed in cylindrical water phantoms of 40-cm diameter and 40-cm height are modeled in either homogeneous phantoms or shielded by Ti, Fe, and Pb filters with thicknesses of 1 and 2 mean free paths. The obtained dose results are compared with corresponding photon Monte Carlo simulations. A 210-group photon cross-section library for applications in this energy range is developed and applied, together with a general-purpose 42-group library developed at Los Alamos National Laboratory, for DANTSYS calculations. The accuracy of DANTSYS with the 42-group library relative to Monte Carlo exhibits large pointwise fluctuations from -42 to +84%. The major cause for the observed discrepancies is determined to be the inadequacy of the weighting function used for the 42-group library derivation. DANTSYS simulations with a finer 210-group library show excellent accuracy on and off the source transverse plane relative to Monte Carlo kerma calculations, varying from minus4.9 to 3.7%. The P 3 Legendre polynomial expansion of the angular scattering function is shown to be sufficient for accurate calculations. The results demonstrate that DANTSYS is capable of calculating photon doses in very good agreement with Monte Carlo and that the multigroup cross-section library and efficient techniques for mitigation of ray effects are critical for accurate discrete ordinates implementation

    The development of gastro-oesophageal reflux disease (GORD) is known to be a causative risk factor in the evolution of adenocarcinoma of the oesophagus. The major component of this reflux is gastric acid. However, the impact of low pH on gene expression has not been extensively studied in oesophageal cells. This study utilizes a transcriptomic and bioinformatic approach to assess regulation of gene expression in response to low pH. In more detail, oesophageal adenocarcinoma cell lines were exposed to a range of pH environments. Affymetrix microarrays were used for gene-expression analysis and results were validated using cycle limitation and real-time RT-PCR analysis, as well as northern and western blotting. Comparative promoter transcription factor binding site (TFBS) analysis (MatInspector) of hierarchically clustered gene-expression data was employed to identify the elements which may co-ordinately regulate individual gene clusters. Initial experiments demonstrated maximal induction of EGR1 gene expression at pH 6.5. Subsequent array experimentation revealed significant induction of gene expression from such functional categories as DNA damage response (EGR1-4, ATF3) and cell-cycle control (GADD34, GADD45, p57). Changes in expression of EGR1, EGR3, ATF3, MKP-1, FOSB, CTGF and CYR61 were verified in separate experiments and in a variety of oesophageal cell lines. TFBS analysis of promoters identified transcription factors that may co-ordinately regulate gene-expression clusters, Cluster 1: Oct-1, AP4R; Cluster 2: NF-kB, EGRF; Cluster 3: IKRS, AP-1F. Low pH has the ability to induce genes and pathways which can provide an environment suitable for the progression of malignancy. Further functional analysis of the genes and clusters identified in this low pH study is likely to lead to new insights into the pathogenesis and therapeutics of GORD and oesophageal cancer.

    The present studies examined the effect of agents that induce peroxisomal and mitochondrial beta-oxidation on hepatic mitochondrial carnitine palmitoyltransferase (CPT) and peroxisomal carnitine acyltransferase [CPTs of Ramsay (1988) Biochem. J. 249, 239-245; COT of Farrell & Bieber (1983) Arch. Biochem. Biophys. 222, 123-132 and Miyazawa, Ozasa, Osumi & Hashimoto (1983) J. Biochem. 94, 529-542]. In the first studies, high fat diets containing corn oil or fish oil were used to induce peroxisomal and mitochondrial enzymes. Rats were fed one of three diets for 4 weeks: (1) low fat, with corn oil as 11% of energy (kJ); (2) high fat, with corn oil as 45% of kJ; (3) high fat, with fish oil as 45% of kJ. At the end of 4 weeks, both mitochondrial CPT and peroxisomal CPTs exhibited increases in activity, immunoreactive protein, mRNA levels and transcription rates in livers of rats fed either high-fat diet compared to the low fat diet. Riboflavin deficiency or starvation for 48 h also increased the peroxisomal CPTs mRNA. A second set of studies used the plasticizer 2-(diethylhexyl)phthalate (DEHP), 0.5% clofibrate or 1% acetylsalicylic acid (fed for 3 weeks) to alter peroxisomal and mitochondrial fatty acid oxidation. With DEHP, the mitochondrial CPT and peroxisomal CPTs activity, immunoreactive protein, mRNA levels and and transcription rate were all increased by 3-5-fold. The peroxisomal CPTs activity, immunoreactive protein, mRNA levels and transcription rate were increased 2-3-fold by clofibrate and acetylsalicylic acid, again similar to mitochondrial CPT. The results of the combined studies using both diet and drugs to cause enzyme induction suggest that the synthesis of the carnitine acyltransferases (mitochondrial CPT and peroxisomal CPTs) may be co-ordinated with each other; however, the co-ordinate regulatory factors have not yet been identified.

  3. Development of a new adaptive ordinal approach to continuous-variable probabilistic optimization.

    A very general and robust approach to solving continuous-variable optimization problems involving uncertainty in the objective function is through the use of ordinal optimization. At each step in the optimization problem, improvement is based only on a relative ranking of the uncertainty effects on local design alternatives, rather than on precise quantification of the effects. One simply asks ''Is that alternative better or worse than this one?'' -not ''HOW MUCH better or worse is that alternative to this one?'' The answer to the latter question requires precise characterization of the uncertainty--with the corresponding sampling/integration expense for precise resolution. However, in this report we demonstrate correct decision-making in a continuous-variable probabilistic optimization problem despite extreme vagueness in the statistical characterization of the design options. We present a new adaptive ordinal method for probabilistic optimization in which the trade-off between computational expense and vagueness in the uncertainty characterization can be conveniently managed in various phases of the optimization problem to make cost-effective stepping decisions in the design space. Spatial correlation of uncertainty in the continuous-variable design space is exploited to dramatically increase method efficiency. Under many circumstances the method appears to have favorable robustness and cost-scaling properties relative to other probabilistic optimization methods, and uniquely has mechanisms for quantifying and controlling error likelihood in design-space stepping decisions. The method is asymptotically convergent to the true probabilistic optimum, so could be useful as a reference standard against which the efficiency and robustness of other methods can be compared--analogous to the role that Monte Carlo simulation plays in uncertainty propagation.

    This study evaluated the effect of Taiwan's smoke-free ordinance and media campaigns on public awareness and secondhand smoke exposure. The authors conducted 3 waves of research--in July 2008 (before media campaigns), in December 2008 (during media campaigns), and in March 2009 (3 months after implementation of the smoke-free law). National representative samples of 1074, 1084, and 1094 people, respectively, were interviewed successfully by telephone in the 3 surveys. The results showed that general awareness of smoke-free workplace legislation rose dramatically from 28.5% in July 2008 to 87.6% in December 2008 to 93.6% in March 2009. Exposure to secondhand smoke in the workplace fell from 28.5% in July 2008 to 24.9% in December 2008 to 7.3% in March 2009, and household secondhand smoke exposure decreased from 36.8% to 34.3% to 21.3%, respectively, during the same period. Multivariate analyses results indicated that media campaigns, smoke-free ordinance implementation, having higher education, and having higher income were associated with more awareness of the smoke-free workplace legislation. In addition, smoke-free ordinance implementation, being female, having higher education, and having higher income were associated with less likelihood of reporting secondhand smoke exposure in the workplace. In conclusion, smoke-free ordinance implementation and media campaigns were effective in raising public awareness of the new law and reducing secondhand smoke exposure in workplaces, in public places, and at home.

    Full Text Available Nel 1849 le truppe austriache penetrarono nel Granducato toscano permettendo il rientro di Leopoldo II e segnando l’inizio di una nuova restaurazione. Il ritorno all’ordine pre-rivoluzionario non fu però agevolato dalla presenza della milizia straniera che, lungi dall’essere provvisoria, sollevò problemi di natura non solo economica e politico-organizzativa ma anche sanitaria. In particolare, la recrudescenza del morbo sifilitico tra le file dei militari, diretta conseguenza della crescita nella domanda e nell’offerta del sesso mercenario, costrinse il governo granducale a studiare provvedimenti sanitari contro le ‘femmine infet- tatrici’. L’incarico, affidato al prefetto di Firenze e portato a compimento nel 1855, implicò la raccolta di precedenti disposizioni, progetti di regolamento, suggerimenti e rapporti sulla prostituzione rintracciabili in due nuclei di carte conservati nel fondo della Prefettura del compartimento fiorentino. I documenti qui presentati, vale a dire le relazioni dei delegati di Governo dei quartieri di Santa Maria Novella e di Santo Spirito redatte nel novembre 1849, offrono uno spaccato inedito, intenso e vivace non solo del meretricio fiorentino ma anche delle tensioni e delle fratture sottese all’universo femminile ottocentesco.

    We assessed reproducible definition of two standardized co-ordinate systems for intersubject analysis of brain images. The baselines in the two co-ordinate systems were a modification of the canthomeatal (mCM) line and the anterior-posterior commissural (AC-PC) line. Axial spin-echo MR images of four subjects at 1.5T were used. Operator error was computed from the replicate analyses of two operators. The mCM line was determined by the lens of the eye and the internal auditory canal, and the AC-PC line was determined by the intersection of AC and PC with the interhemispheric fissure. Reproducibility of the mCM markers (SD = 0.59 mm) did not differ significantly from that of the AC-PC line (SD = 0.68 mm). The measurement error of the angle of the baseline (delta alpha), however, was more than 7 times as large for the AC-PC line as for the mCM line. An additional error affecting the rostrocaudal rotation of the co-ordinate systems, attributable to the distance between the anatomic markers, was 2.1 and 3.6 degrees (3 mm and 5 mm slice thickness) for the mCM co-ordinate system and 8.2 and 11.0 degrees (3 mm and 5 mm slice thickness) for the AC-PC system. The AC-PC line based co-ordinate system is therefore, less reproducible than the mCM line based system. This could be improved if a combination of axial and sagittal images were used for the definition of the AC-PC line.

    Achieving co-ordinate, high-level and stable expression of multiple transgenes in plants is currently difficult. Expression levels are notoriously variable and influenced by factors that act independently on transgenes at different genetic loci. Instability of expression due to loss, re-arrangement or silencing of transgenes may occur, and is exacerbated by increasing numbers of transgenic loci and repeated use of homologous sequences. Even linking two or more genes within a T-DNA does not necessarily result in co-ordinate expression. Linking proteins in a single open reading frame--a polyprotein--is a strategy for co-ordinate expression used by many viruses. After translation, polyproteins are processed into constituent polypeptides, usually by proteinases encoded within the polyprotein itself. However, in foot-and-mouth disease virus (FMDV), a sequence (2A) of just 16-20 amino acids appears to have the unique capability to mediate cleavage at its own C-terminus by an apparently enzyme-independent, novel type of reaction. This sequence can also mediate cleavage in a heterologous protein context in a range of eukaryotic expression systems. We have constructed a plasmid in which the 2A sequence is inserted between the reporter genes chloramphenicol acetyltransferase (CAT) and beta-glucuronidase (GUS), maintaining a single open reading frame. Here we report that expression of this construct in wheatgerm lysate and transgenic plants results in efficient cleavage of the polyprotein and co-ordinate expression of active CAT and GUS. Self-processing polyproteins using the FMDV 2A sequence could therefore provide a system for ensuring co-ordinated, stable expression of multiple introduced proteins in plant cells.

    1998-11-01

    In 1986 the Animal Production and Health Section of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture embarked on a programme of support to scientists in developing countries focused on improving animal disease diagnosis through the use of nuclear and related technologies. As part of this programme the Swedish International Development Authority (SIDA) agreed to provide support for a FAO/IAEA Co-ordinated Research Project (CRP) concerned with the introduction and use of such technologies in Latin America. Through this programme, which was entitled Regional Network for Latin America on Animal Disease Diagnosis Using Immunoassays and Labeled DNA Probe Techniques, studies were supported on a number of diseases considered to be of substantial economic and social importance to the region, including brucellosis, tuberculosis, babesiosis, leukosis, bluetongue and chlamydia infection in cattle and psedorabies in pigs. One significant conclusion was that large number of diseases studied limited research findings owing to the lack of a critical mass of scientists studying any one specific disease problem. Thus when in 1991, SIDA agreed to follow-up CRP on Immunoassay Methods for the Diagnosis and Epidemiology of Animal Diseases in Latin America, the work was restricted to three diseases, i.e. foot-and-mouth disease (FMD), bovine brucellosis and bovine babesiosis. In 1994 results were presented in Guadeloupe, Lesser Antilles, France. The outcome of this meeting was the validation of ELISAs for the above mentioned diseases and a recommendation that future research should focus on diagnosis and epidemiology to support existing control and eradication campaigns against the two diseases of major importance in the region (FMD and Brucellosis). A follow-up CRP (1994-1997) entitled the Use of ELISA for Epidemiology and Control of Foot-and-Mouth Disease and Bovine Brucellosis in Latin America focused on the further validation and subsequent use of a

    Full Text Available Nei nostri tempi si sviluppa un nuovo metodo di eseguire il canto gregoriano, ispirato al lavoro di E. Cardine, Semiologie Grégorienne (Extrait des Etudes Grégoriennes, Tome XI, Solesmes 1970, ma anche alla pratica di canto da parte dei monaci orientali e dei cantori dalle isole del Mar Mediterraneo. Le spiegazioni della ricca tradizione di Solesmes vengono messe in discussione. Nel pressus i cantori fanno la ripercussione delle note colla stessa altezza, spesso in modo nervoso. Si cerca di badare tutti i dati degli antichi manoscritti e di eseguire esattamente i più piccoli segmenti, a scapito di frasi più grandi e d’insieme di un canto. Interessanti sono gli studi sul trattato di Girolamo di Moravia, ma bisogna sapere che questo è una fonte del canto del XIII secolo, autentico solo per l’Ordine dei Predicatori. Dal IX secolo molti musicisti s’interessavano più alla primitiva musica polifonica che al monodico canto gregoriano. Sarebbe bene studiare gl’influssi orientali sul canto della Chiesa latina e i costumi dei monaci e dei cantori diocesani dei duomi e delle collegiate nel medioevo per conoscere meglio le autentiche tradizioni, ma è una cosa per gli specialisti; gli elementi orientali interessano solo i giovani musicisti e quelli più maturi. Invece nella pratica quotidiana del canto gregoriano importante è che ciascuno brano venga eseguito con i suoi dati specifici senza mescolanza e sincretismo e poi le cose concrete come: la conoscenza del senso dei testi liturgici latini, l’altezza commoda per i cantori, il tempo moderato, non troppo lento e non troppo veloce, il modo normale di cantare dei solisti e dei gruppi.

  18. Combination processes for food irradiation. Proceedings of the final research co-ordination meeting

    International Nuclear Information System (INIS)

    1998-01-01

    There is an increasing consumer demand for food that is safe, minimally processed, visually attractive, full flavoured, nutritious, and convenient to prepare and serve, that has fewer preservatives, and that is available throughout the year at an affordable cost. Consumer concern and regulatory restrictions on the use of preservatives and pesticides in food are adversely affecting international trade in many food products. As a result, minimally processed, chilled foods and ready to eat foods are increasingly being marketed to satisfy consumer demand in both developed and developing countries. However, such foods could introduce new microbiological risks to the population, especially to those who are immunocompromised or generally at risk (children, pregnant women, the elderly, etc.). In view of these factors, a 5 year Co-ordinated Research Programme (CRP) on Irradiation in Combination with Other Processes for Improving Food Quality was initiated in 1991 by the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency through their Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. The objectives of this CRP were to evaluate: 1) Combination treatment involving irradiation in order to extend the self-life of meat, seafood, fruits and vegetables at refrigeration temperatures and under ambient conditions; 2) Combination treatment involving irradiation in order to ensure the microbiological safety of foods, both individual and composite, including prepared meals; 3) Shelf-life extension of chilled, prepared meals and the development of shelf stable food and food components through combination treatment involving irradiation; 4) Energy requirements of combination processes involving irradiation in comparison to other food processes. Scientists from 14 countries participated in the CRP by carrying out the work under Research Contracts and Agreements with the Joint FAO/IAEA Division. The first Research Co-ordination

    Every year, an average of eight new civilian remote sensing satellite missions are launched. Cumulatively, over 250 such missions, each with a cost equivalent in current value to between US 100 million to US 1000 million, have been sponsored by space agencies in perhaps two dozen countries. These missions produce data and information products which are vital for informed decision making all over the world, on matters relating to natural resource exploitation, health and safety, sustainable national development, infrastructure planning, and a host of other applications. By contributing to better scientific understanding of global changes in the atmosphere, land surface, oceans and ice caps, these silently orbiting sentinels in the sky make it possible for governments and industries to make wiser environmental policy decisions and support the economic development needs of humanity. The international Committee on Earth Observation Satellites (CEOS) is the premier world body for co-ordinating and planning civilian satellite missions for Earth observation. Through its technical working groups and special task teams, it endeavours to: • maximise the international benefits from Earth observation satellites; and • harmonise practice in calibration, validation, data management and information systems for Earth observation. CEOS encompasses not only space agencies (data providers), but also the great international scientific and operational programs which rely on Earth science data from space. The user organisations affiliated with CEOS, together with the mission operators, attempt to reconcile user needs with the complex set of considerations — including national interests, cost, schedule — which affect the undertaking of space missions. Without such an internationally co-ordinated consensual approach, there is a much greater risk of waste through duplication, and of missed opportunity, or through the absence of measurements of some vital physical or biological

    Full Text Available Milkability traits have an increasing importance in modern cattle production, although they are the secondary selective trait. The machine milking of cows has indicated that there is no complete alignment between the machine and the animals, what lead to increasing duration of milking and disturbances in health of udder. Because of that, the aim of this study was to investigate the influence of the ordinal number of lactation and stage of lactation on milkability traits (amount of milk per milking (KMM, maximum milk flow rate (MPM, average milk flow rate (PPM, duration of the start of milk flow (tS500, duration of the ascending phase of milking (tUFM, duration of the plateau phase of milking (tPFM, duration of the descending phase of milking (tSFM, duration of the main phase of milking (tGFM, and recommend the same for the selection work. The study was done on 322 Holstein cows in the period from the first to third lactation, arranged in three stages of lactation (the first of the 50-90 day, the second stage of the 91-135 day and a third of 136-180 day of lactation. The results showed that the ordinal number of lactation had a highly statistically significant influence (P<0.01 on KMM and MPM, and on the PPM and tGFM (P<0.05. Statistically significant influence of the stage of lactation on the KMM was recorded in the first and second lactation (P<0.05 respectively in the third lactation (P<0.01. Was recorded a significant positive influence of KMM (P<0.05 on the MPM, tPFM, tSFM and tGFM (r = from 0.22 to 0.52. The negative correlation of the MPM (P<0.05 was recorded with some parts of the milking phase duration (r = -0.14 to -0.47. The results indicate that there are opportunities for selection work to improve milkability traits, which can have a positive impact on the economy of expenditure of time during milking, and indirectly improve the health of the udder.

  1. Co-ordinated research project: comparative international studies of osteoporosis using isotope techniques

    International Nuclear Information System (INIS)

    1998-01-01

    Poor bone health is a major public health problem of worldwide concern. No country is immune. One of the main concerns - osteoporosis - is a bone disease that usually affects older people (primarily post-menopausal women), leading to hip fractures, vertebral compression fractures, and other related problems.In 1994 the IAEA (henceforth the 'Agency') started a 5-year Co-ordinated Research Programme (CRP) which addresses one particular measure of bone health - bone mineral density (BMD). The main concept underpinning this CRP is that good bone health in later years is primarily determined by the attainment of a sufficiently high BMD during early adulthood. The 'core' objective of the Agency's CRP is to investigate how BMD varies with the age, sex, ethnicity and geographical origin of the subjects over the age range from 15 to 50 years. This is being done in the hopeful expectation that, by looking at a large number of population groups with different lifestyle, nutritional and other parameters, it might be possible to obtain some new insights into which factors are important for attaining a high value of BMD during early adulthood, and for being able to maintain it at a sufficiently high level into old age. The Second Research Co-ordination Meeting (RCM) for participants in the CRP - which is the subject of the present report - was held at the University of California San Diego (UCSD), USA. An overview of the data on BMD reported by the participants during the meeting. It is concluded that the CRP participants have gathered an impressive amount of data over the last 2 years. Given the fact that some age groups contain relatively small numbers of subjects, the statistical uncertainties are still relatively large. Nevertheless, there do appear to be quite marked differences in BMD across the centres, approaching approximately 10%. If confirmed, this could represent a major difference in fracture risk for the future, if all other factors (bone quality, weight, fall

    Article III of the IAEA Statute authorises the Agency to encourage and assist research on, and development and practical application of, atomic energy for peaceful purposes throughout the world and to foster the exchange of scientific and technical information, as well as the exchange of scientists in the field of peaceful uses of atomic energy. The research supported by the Agency is within the framework of the Agency's programmes, sub-programmes and projects that are listed in the approved Programme and Budget of the Agency. The research work is normally implemented through Coordinated Research Projects (CRPs) that bring together research institutes in both developing and developed Member States to collaborate on the research topic of interest. In addition, the introduction of a new type of CRP (called Thematic CRP), meant to complement traditional CRPs, is currently being tested by the Human Health programme. This new, optional type of CRP is designed to strengthen promotion of research on nuclear technologies in developing Member States through CRPs that rest on pair building between agreement holders and contract holders and includes a PhD training programme at the contract holders' institutions. Further details of the administration of research contracts and general information on CRPs is contained in the Agency?s Website at http://www.iaea.org/programmes/ri/uc.html. The CRPs reported in this document are conducted in support of the following Agency programmes: Nuclear Power; Nuclear Fuel Cycle and Waste Management Technology; Comparative Assessment for Sustainable Energy Development; Food and Agriculture; Human Health; Marine Environment and Water Resources; Applications of Physical and Chemical Sciences; Nuclear Safety; Radiation Safety; Radioactive Waste Safety; Co-ordination of Safety Activities; Safeguards. The Sub-programmes supported by the CRPs are listed. Results of research are available to all Member States, and are disseminated through national

    Full Text Available Both in the Spanish legal system as, in general, in comparative law, there are two distinct approaches to gender violence. On the one hand, there are supporters of “victim choice”, on the other hand, an approach supporting the benefits of the implementation of no-drop policies might prevail. In the Spanish legal system, both of these approaches coexist and this article aims to examine this. Moreover, in this paper, the author underlines in particular the difficulties coming from the numerous refusals to report such violence and from the frequent retractions of the victims of this kind of crime. Tant dans le système juridique espagnol que, en général, dans le droit comparé, il existe, en matière de violences liées au genre, deux positions : d’un côté, certains sont partisans d’une approche dite victim choice, de l’autre quelques-uns préfèreraient appliquer celle appelée no–drop policies. Dans le système juridique espagnol, ces deux positions coexistent et cet article a comme objectif de les examiner. En outre, dans ce texte, l’auteur souligne tout particulièrement les difficultés dues aux nombreux refus de déposer plainte et aux rétractations fréquentes des victimes, fréquents dans le cadre de ce type de violence.

    In the developed countries, research using nuclear methods has been substantially used to examine the physiological and biochemical mechanisms involved in obesity-related diseases. This Co-ordinated Research Project (CRP) is intended to promote the use of these techniques in the developing world. The specific objectives of this CRP are: 1. To define the magnitude of the obesity/NIDDM problem in developing countries. 2. To identify vulnerable groups at high risk. 3. To describe the metabolic mechanisms involved. The purpose of this first Research Co-ordination Meeting (RCM) was thus to develop a worldwide collaboration in the use of nuclear and isotopic techniques to investigate the aetiology of degenerative diseases in ageing. All countries participating in this CRP are going through the epidemiological transition with changes in lifestyles to approach those seen in the developed nations

    Full Text Available Il contributo fa luce sul complesso rapporto tra il tardo-duecen­tesco Roman de Flamenca, esponente tra i piú rilevanti dell’“eccezione narrativa” occitana, e il tipo letterario della lirica trobadorica. Dal suo reimpiego nel ro­manzo, infatti, l’esperienza del grande canto cortese subirà una torsione dei pro­pri presupposti costitutivi, sia per l’inedito protagonismo ora assunto dalla domna e opposto al vuoto provocato dall’assenza dell’altro-da-sé (cioè dell’alterità femminile in cui la poesia della fin’amor aveva trovato il proprio spazio di esi­stenza, sia perché la dimensione cronologica indispensabile alla diegesi investe anche l’apporto della lirica, piegandola e funzionalizzandola alle esigenze del narrazione. The paper sheds light on the relationship between the late-thir­teenth-century Roman de Flamenca, one of the most important exponent of the Occitan “narrative exception”, and the literary genre of the troubadour lyric poetry. The tradition of the grand chant courtois re-used in the novel, in fact, un­dergoes a mutation of its constituent assumptions. This is due both for the unprecedented protagonism assumed by the domna, contrasting the absence of woman’s otherness in which the courtly love poetry founded its space, and be­cause the chronological dimension, which is essential to the diegesis, also invol­ves its lyric sources bending them to the demands of the narrative.

  11. Applications of the Discrete ordinates of Oak ridge System (DOORS) package to Nuclear Engineering problems

    Azmy, Y.Y.

    2004-01-01

    Particle transport problems are notorious for their difficulty. This fact requires that production level computer codes designed to address realistic engineering problems possess three important features: (i) high computational efficiency as measured by solution accuracy for a fixed computational cost; (ii) a wide variety of options to enhance robustness of the transport solver; and (iii) a broad collection of support codes that extend the reach of the transport solver to a wide variety of applications. The Discrete Ordinates of Oak Ridge System (DOORS) code package was designed with these features in mind. In this paper, capabilities of member codes in the DOORS package are overviewed with particular emphasis on two newly developed peripheral codes: BOT3P the mesh-generation and visualization code package, and GipGui the graphical user interface for the cross section manipulation code, GIP. Two large applications are used to illustrate the tight coupling between the peripheral codes and the DORT and TORT transport solvers in two and three dimensional geometries, respectively. These are: (i) criticality calculations for the C5G7MOX core benchmark; and (ii) dose distribution calculations for the Target Service Cell (TSC) of the Spallation Neutron Source (SNS). (Author)

    This publication outlines the 'medical research' licensing procedure as specified in the amendment of the German Radiation Protection Ordinance of November 1, 2011. The general licensing requirements for the use of radiation have not been changed by the amendment. Three so-called use restrictions (i.e., dose limits of 10 mSv and 20 mSv, age limit of 50 years) have been modified. They will only apply to healthy volunteers in the future. In addition, there are considerable simplifications with respect to applications and licensing procedures of the Federal Office for Radiation Protection (Bundesamt fuer Strahlenschutz, BfS) regarding the use of radiation in the newly introduced 'accompanying diagnostics' ('Begleitdiagnostik') case group. The newly established, independent panel of experts at the German Radiological Society (Deutsche Roentgengesellschaft, DRG) may provide essential support to principal investigators, qualified physicians and sponsors for differentiating between 'medical research' and 'health care', the latter not being subject to licensing. An expert statement will be issued by the DRG within four weeks of an inquiry. This consulting service is subject to confidentiality, and is free of charge for inquirers and without any commitment.

  13. Experiences in the parallelization of the discrete ordinates method using OpenMP and MPI

    Pautz, A.; Langenbuch, S.

    2003-01-01

    The method of Discrete Ordinates is in principle parallelizable to a high degree, since the transport 'mesh sweeps' are mutually independent for all angular directions. However, in the well-known production code Dort such a type of angular domain decomposition has to be done on a spatial line-byline basis, causing the parallelism in the code to be very fine-grained. The construction of scalar fluxes and moments requires a large effort for inter-thread or inter-process communication. We have implemented two different parallelization approaches in Dort: firstly, we have used a shared-memory model suitable for SMP (Symmetric Multiprocessor) machines based on the standard OpenMP. The second approach uses the well-known Message Passing Interface (MPI) to establish communication between parallel processes running in a distributed-memory environment. We investigate the benefits and drawbacks of both models and show first results on performance and scaling behaviour of the parallel Dort code. (authors)

  15. Co-ordinated research programme on nuclear techniques for toxic elements in foodstuffs

    International Nuclear Information System (INIS)

    1988-01-01

    The purpose of this Co-ordinated Research Programme (CRP) is to obtain comparative data on the existing elemental concentrations of potentially toxic elements in foodstuffs in various countries. This study is also intended to provide information on the dietary intakes of toxic elements as a means to detect potential health hazards to the population groups concerned. This study has important economic implications since trade in foodstuffs is dependent on compliance with regulations pertaining to maximum permissible concentrations. An important supplementary purpose of the programme is to help establish analytical expertise for work of this kind in individual countries, allowing such laboratories to offer analytical quality control services. The programme has centred its objective on the determination of important toxic elements such as As, Cd, Cr, Hg, Pb and Se, in addition to Cu, Sb and Zn, which are also potentially toxic but are generally of minor importance from the point of view of public health. The matrices of interest are foodstuffs which comprise together more than 50% of the average daily intake. Drinking water is also of high importance and should be analysed as well.

  16. Denovo--A New Three-Dimensional Parallel Discrete Ordinates Code in SCALE

    International Nuclear Information System (INIS)

    Evans, Thomas M.; Stafford, Alissa; Clarno, Kevin T.

    2010-01-01

    Denovo is a new, three-dimensional, discrete ordinates (SN) transport code that uses state-of-the-art solution methods to obtain accurate solutions to the Boltzmann transport equation. Denovo uses the Koch-Baker-Alcouffe parallel sweep algorithm to obtain high parallel efficiency on O(100) processors on XYZ orthogonal meshes. As opposed to traditional SN codes that use source iteration, Denovo uses nonstationary Krylov methods to solve the within-group equations. Krylov methods are far more efficient than stationary schemes. Additionally, classic acceleration schemes (diffusion synthetic acceleration) do not suffer stability problems when used as a preconditioner to a Krylov solver. Denovo's generic programming framework allows multiple spatial discretization schemes and solution methodologies. Denovo currently provides diamond-difference, theta-weighted diamond-difference, linear-discontinuous finite element, trilinear-discontinuous finite element, and step characteristics spatial differencing schemes. Also, users have the option of running traditional source iteration instead of Krylov iteration. Multigroup upscatter problems can be solved using Gauss-Seidel iteration with transport, two-grid acceleration. A parallel first-collision source is also available. Denovo solutions to the Kobayashi benchmarks are in excellent agreement with published results. Parallel performance shows excellent weak scaling up to 20000 cores and good scaling up to 40000 cores.

  17. Fisher Scoring Method for Parameter Estimation of Geographically Weighted Ordinal Logistic Regression (GWOLR) Model

    Science.gov (United States)

    Widyaningsih, Purnami; Retno Sari Saputro, Dewi; Nugrahani Putri, Aulia

    2017-06-01

    GWOLR model combines geographically weighted regression (GWR) and (ordinal logistic reression) OLR models. Its parameter estimation employs maximum likelihood estimation. Such parameter estimation, however, yields difficult-to-solve system of nonlinear equations, and therefore numerical approximation approach is required. The iterative approximation approach, in general, uses Newton-Raphson (NR) method. The NR method has a disadvantage—its Hessian matrix is always the second derivatives of each iteration so it does not always produce converging results. With regard to this matter, NR model is modified by substituting its Hessian matrix into Fisher information matrix, which is termed Fisher scoring (FS). The present research seeks to determine GWOLR model parameter estimation using Fisher scoring method and apply the estimation on data of the level of vulnerability to Dengue Hemorrhagic Fever (DHF) in Semarang. The research concludes that health facilities give the greatest contribution to the probability of the number of DHF sufferers in both villages. Based on the number of the sufferers, IR category of DHF in both villages can be determined.

  18. Discrete ordinates transport methods for problems with highly forward-peaked scattering

    Pautz, S.D.

    1998-04-01

    The author examines the solutions of the discrete ordinates (S N ) method for problems with highly forward-peaked scattering kernels. He derives conditions necessary to obtain reasonable solutions in a certain forward-peaked limit, the Fokker-Planck (FP) limit. He also analyzes the acceleration of the iterative solution of such problems and offer improvements to it. He extends the analytic Fokker-Planck limit analysis to the S N equations. This analysis shows that in this asymptotic limit the S N solution satisfies a pseudospectral discretization of the FP equation, provided that the scattering term is handled in a certain way (which he describes) and that the analytic transport solution satisfies an analytic FP equation. Similar analyses of various spatially discretized S N equations reveal that they too produce solutions that satisfy discrete FP equations, given the same provisions. Numerical results agree with these theoretical predictions. He defines a multidimensional angular multigrid (ANMG) method to accelerate the iterative solution of highly forward-peaked problems. The analyses show that a straightforward application of this scheme is subject to high-frequency instabilities. However, by applying a diffusive filter to the ANMG corrections he is able to stabilize this method. Fourier analyses of model problems show that the resulting method is effective at accelerating the convergence rate when the scattering is forward-peaked. The numerical results demonstrate that these analyses are good predictors of the actual performance of the ANMG method

    Full Text Available Introduction: For children ages 1-14, 21.6% of drowning cases involve swimming, wading, orplaying in natural bodies of water, such as rivers and lakes. Personal flotation devices (PFDs arebelieved to be an effective prevention measure. We measure compliance with city and countyordinances, publicized but not actively enforced, requiring that PFDs be worn by children accessingpublic bodies of water in Sacramento County, California.Methods: During June-August 2010, volunteers conducted 79 observation sessions at threepopular local river beaches where PFDs were available for use at no cost. They recorded personalcharacteristics and PFD use for 1,727 children in or very near the water and believed to be 0-13years of age (the age covered by the ordinances. We used logistic regression to quantify differencesin use by subject characteristics and study site.Results: The prevalence of PFD use was 29.9% overall, with large and significant differencesby age: < 1, 55.6%; 1-4, 37.6%; 5-10, 29.4%; 10-13, 14.6%; P < 0.0001. Usage did not varysignificantly by sex or race/ethnicity, and was somewhat higher at one study site (33.1% than at theothers (25.9% and 27.3%, P = 0.009.Conclusion: The combination of a statutory requirement and a cost-elimination strategy wasassociated with moderate rates of PFD use that were highest among young children.

  20. Wormhole Detection Based on Ordinal MDS Using RTT in Wireless Sensor Network

    2016-01-01

    Full Text Available In wireless communication, wormhole attack is a crucial threat that deteriorates the normal functionality of the network. Invasion of wormholes destroys the network topology completely. However, most of the existing solutions require special hardware or synchronized clock or long processing time to defend against long path wormhole attacks. In this work, we propose a wormhole detection method using range-based topology comparison that exploits the local neighbourhood subgraph. The Round Trip Time (RTT for each node pair is gathered to generate neighbour information. Then, the network is reconstructed by ordinal Multidimensional Scaling (MDS followed by a suspicion phase that enlists the suspected wormholes based on the spatial reconstruction. Iterative computation of MDS helps to visualize the topology changes and can localize the potential wormholes. Finally, a verification phase is used to remove falsely accused nodes and identify real adversaries. The novelty of our algorithm is that it can detect both short path and long path wormhole links. Extensive simulations are executed to demonstrate the efficacy of our approach compared to existing ones.

  1. Sec. 46 of the radiation protection ordinance - waiting for implementing regulations

    International Nuclear Information System (INIS)

    Maushart, R.

    1977-01-01

    There is much uncertainty among the users of radioactive substances in research and medicine about the practical consequences stemming from Sec. 46 of the new Radiation Protection Ordinance with respect to releases of radionuclides with the air and water. On the one hand, the 30 mrem concept has drastically curbed permissible release concentrations. In addition, balancing for each specific nuclide has become compulsory. Both conditions would demand a revision and extension of present measuring techniques. However, the responsible supervisory authorities are unable to issue any rules or regulations as long as there are no uniform standards. The consequence is a complete lack of knowledge, both on the part of users and the supplying industries, about the future expenditure necessary for liquid and gaseous effluent control and the technical performance criteria to be met by radiation measuring equipment. It is to be hoped that these implementing regulations, which are so urgently needed, will soon be published so as to allow users to engage in meaningful and binding planning again, both technically and financially.

  2. The TORT three-dimensional discrete ordinates neutron/photon transport code (TORT version 3)

    Rhoades, W.A.; Simpson, D.B.

    1997-10-01

    TORT calculates the flux or fluence of neutrons and/or photons throughout three-dimensional systems due to particles incident upon the system`s external boundaries, due to fixed internal sources, or due to sources generated by interaction with the system materials. The transport process is represented by the Boltzman transport equation. The method of discrete ordinates is used to treat the directional variable, and a multigroup formulation treats the energy dependence. Anisotropic scattering is treated using a Legendre expansion. Various methods are used to treat spatial dependence, including nodal and characteristic procedures that have been especially adapted to resist numerical distortion. A method of body overlay assists in material zone specification, or the specification can be generated by an external code supplied by the user. Several special features are designed to concentrate machine resources where they are most needed. The directional quadrature and Legendre expansion can vary with energy group. A discontinuous mesh capability has been shown to reduce the size of large problems by a factor of roughly three in some cases. The emphasis in this code is a robust, adaptable application of time-tested methods, together with a few well-tested extensions.

    The crystal structure of [Usup(IV)(PhCOCHCOPh)4- has been determined at 295 K from X-ray diffraction data refined by least squares to a residual of 0.042 for 2 257 'observed' reflections. Crystals are orthorhombic, space group Pccn, with unit-cell dimensions a = 10.323(8), b = 20.172(15), c = 23.65(2) A, and Z = 4; they are isostructural with the previously studied cerium analogue, the eight-co-ordinate uranium atom lying on a crystallographic two-fold axis, with U - O ranging from 2.323(7) to 2.370(6) A. For the cerium analogue, a = 10.29(1), b = 20.07(3), and c = 23.42(4) A; R = 0.043 for 1 817 'observed' reflections. The corresponding Ce - O distances lie between 2.291(7) and 2.348(6) A. The stereochemistries of these complexes are close to square antiprismatic with the bidentate ligands spanning opposite square faces, as predicted by electron-pair repulsion theory. (author)

  4. Estimating continuous floodplain and major river bed topography mixing ordinal coutour lines and topographic points

    Bailly, J. S.; Dartevelle, M.; Delenne, C.; Rousseau, A.

    2017-12-01

    Floodplain and major river bed topography govern many river biophysical processes during floods. Despite the grow of direct topographic measurements from LiDARS on riverine systems, it still room to develop methods for large (e.g. deltas) or very local (e.g. ponds) riverine systems that take advantage of information coming from simple SAR or optical image processing on floodplain, resulting from waterbodies delineation during flood up or down, and producing ordered coutour lines. The next challenge is thus to exploit such data in order to estimate continuous topography on the floodplain combining heterogeneous data: a topographic points dataset and a located but unknown and ordered contourline dataset. This article is comparing two methods designed to estimate continuous topography on the floodplain mixing ordinal coutour lines and continuous topographic points. For both methods a first estimation step is to value each contourline with elevation and a second step is next to estimate the continuous field from both topographic points and valued contourlines. The first proposed method is a stochastic method starting from multigaussian random-fields and conditional simualtion. The second is a deterministic method based on radial spline fonction for thin layers used for approximated bivariate surface construction. Results are first shown and discussed from a set of synoptic case studies presenting various topographic points density and topographic smoothness. Next, results are shown and discuss on an actual case study in the Montagua laguna, located in the north of Valparaiso, Chile.

  6. Performance of the adaptive collision source (ACS) method for discrete ordinates in parallel environments

    International Nuclear Information System (INIS)

    Walters, W.J.; Haghighat, A.

    2013-01-01

    A new collision source method has been developed to solve the Linear Boltzmann Equation (LBE) more efficiently by adaptation of the angular quadrature order. The angular adaptation method is unique in that the flux from each scattering source iteration is obtained separately, with potentially a different quadrature order. This allows for an optimal use of processing power, by using a high order quadrature for the first few iterations that need it, before shifting to lower order quadratures for the remaining iterations. This is essentially an extension of the first collision source method, and we call it the adaptive collision source method (ACS). The ACS methodology has been implemented in the TITAN discrete ordinates code, and has shown a speedup of 2-3 on a test problem, with very little loss of accuracy (within a provided adaptive tolerance). Further, the code has been extended to work in parallel environments by angular decomposition. Although the method requires increased parallel communication, tests have shown excellent scale adaptation, with parallel fractions of up to 99%. (authors)

    The Radiation Protection Association (Fachverband fuer Strahlenschutz) decided to publish explanations for the practical application of the amended Radiation Protection Ordinance, if possible immediately at the time of promulgation. The purpose of this publication is to provide as many advice seekers as possible with whatever information they need for their purposes. The material has therefore been divided into chapters each dedicated to a specific user group. Dedicated chapters containing all the important information for the respective target group have been provided for hospitals and physicians, general and special applications of ionising radiation in industry and trade, companies that perform services in areas or installations exposed to radiation, nuclear power plants and companies affected by the new protective regulations concerning natural radiation. These chapters are supplemented with contributions on generic topics such as the principles of radiation protection, new developments in dosimetry, transport and storage of radioactive substances, expertise and instruction and qualification approval. The section on general topics is rounded off by the transitory regulations, which are crucially important

    This Ordinance sets forth new rules with respect to travel abroad by citizens of the German Democratic Republic. Its major provisions are as follows: 1) the occasions when relatives may travel abroad to other than socialist countries have been increased; 2) travel abroad by pensioners may be undertaken without giving any special reason; 3) travel abroad to socialist countries can be made for any reason; 4) persons may now leave the German Democratic Republic permanently for humanitarian reasons, including the desire of an invalid or old person to receive care or spend his or her days elsewhere and family reunification; 5) requests for permanent departure can be denied on the grounds of national security or defense, because a person has not performed his or her military service, to protect the public order or state interests, and to protect the rights of citizens or socialist morale and social requirements; 6) requests to go abroad temporarily are generally to be handled within 30 days and requests to leave permanently usually within 3 months; 7) adverse decisions may now be appealed both administratively and then through the courts, although in a court the only argument that can be made is that the decision was unlawful; 8) a request that has been denied can be resubmitted if the reason for denial is no longer present; and 9) in the case of a request to leave permanently, 6 months must pass before resubmission.

    Sea disposal operations of packaged low-level radioactive waste are carried out under the provisions of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, also referred to as the London Dumping Convention. The environmental impact of this disposal method is continuously kept under review, in particular within the IAEA which has provided the ''Definition of High-Level Radioactive Waste or Other High-Level Radioactive Matter Unsuitable for Dumping at Sea'' for the purpose of the Convention and within the OECD-NEA in the framework of its Multilateral Consultation and Surveillance Mechanism for Sea Dumping of Radioactive Waste. The NEA Co-Ordinated Research and Environmental Surveillance Programme (CRESP) is focussed on the actual North-East Atlantic dump site. Its objective is to increase the available scientific data base related to the oceanographic and biological characteristics of the dump site and elaborate a site specific model of the transfers of radionuclides to human populations. Future site suitability reviews, as periodically requested under the terms of the Multilateral Consultation and Surveillance Mechanism, will therefore be based on a more accurate and comprehensive scientific basis

  10. nilR is necessary for co-ordinate repression of Xenorhabdus nematophila mutualism genes.

    Science.gov (United States)

    Cowles, Charles E; Goodrich-Blair, Heidi

    2006-11-01

    The bacterial mutualist Xenorhabdus nematophila colonizes a specific region of its nematode host Steinernema carpocapsae. We previously reported the identification of a chromosomal locus encoding three X. nematophila genes of unknown function, nilA, B and C, that are each necessary for colonization. Subsequent work indicated the global regulator Lrp is a repressor of nilC: nilC transcription is elevated in an lrp mutant and Lrp interacts directly with the nilC promoter. In this manuscript, we report the identification of an additional gene, nilR, required for repression of nilC transcription. We show that nilR and lrp mutants also have elevated expression of nilA and nilB, demonstrating that nilA, B and C are co-ordinately regulated. nil gene expression is derepressed most strongly when both nilR and lrp are lacking, suggesting NilR and Lrp synergistically repress nil transcription. NilR contains a helix-turn-helix-type DNA binding domain and likely acts directly at promoters. A comparison of the wild type and nilR proteomes indicates that NilR, unlike Lrp, regulates a small number of genes. Finally, X. nematophila carrying an ectopic copy of nilR colonizes at approximately 60-fold lower levels than the control strain, suggesting that derepression of nil gene expression is necessary for nematode colonization.

    2003-05-20

    We compare Monte Carlo (MC) and discrete-ordinate radiative-transfer (DISORT) simulations of irradiances in a one-dimensional coupled atmosphere-ocean (CAO) system consisting of horizontal plane-parallel layers. The two models have precisely the same physical basis, including coupling between the atmosphere and the ocean, and we use precisely the same atmospheric and oceanic input parameters for both codes. For a plane atmosphere-ocean interface we find agreement between irradiances obtained with the two codes to within 1%, both in the atmosphere and the ocean. Our tests cover case 1 water, scattering by density fluctuations both in the atmosphere and in the ocean, and scattering by particulate matter represented by a one-parameter Henyey-Greenstein (HG) scattering phase function. The CAO-MC code has an advantage over the CAO-DISORT code in that it can handle surface waves on the atmosphere-ocean interface, but the CAO-DISORT code is computationally much faster. Therefore we use CAO-MC simulations to study the influence of ocean surface waves and propose a way to correct the results of the CAO-DISORT code so as to obtain fast and accurate underwater irradiances in the presence of surface waves.

    The contribution of this paper relies in the development of numerical algorithms for the mathematical treatment of specular reflection on borders when dealing with the numerical solution of radiative transfer problems. The radiative transfer equation being integro-differential, the discrete ordinates method allows to write down a set of semi-discrete equations in which weights are to be calculated. The calculation of these weights is well known to be based on either a quadrature or on angular discretization, making the use of such method straightforward for the state equation. Also, the diffuse contribution of reflection on borders is usually well taken into account. However, the calculation of accurate partition ratio coefficients is much more tricky for the specular condition applied on arbitrary geometrical borders. This paper presents algorithms that calculate analytically partition ratio coefficients needed in numerical treatments. The developed algorithms, combined with a decentered finite element scheme, are validated with the help of comparisons with analytical solutions before being applied on complex geometries.

On the other hand, standard preference structures examine decision problems through the decomposition...... of the preference predicate into the simpler situations of strict preference, indifference and incomparability. Hence, following the distinctive cognitive/neurological features for perceiving positive and negative stimuli in separate regions of the brain, we consider two separate and opposite poles of preference...... and aversion, and obtain an extended preference structure named the Preference–aversion (P–A) structure. In this way, examining the meaning of words under an ordinal scale and using CWW’s methodology, we are able to formulate the P–A model under a simple and purely linguistic approach to decision making...

  14. On the spectral nodal methods applied to discrete ordinates eigenvalue problems in Cartesian geometry

    International Nuclear Information System (INIS)

    Abreu, Marcos P. de; Alves Filho, Hermes; Barros, Ricardo C.

    2001-01-01

    We describe hybrid spectral nodal methods for discrete ordinates (SN) eigenvalue problems in Cartesian geometry. These coarse-mesh methods are based on three ingredients: the use of the standard discretized spatial balance SN equations; the use of the non-standard spectral diamond (SD) auxiliary equations in the multiplying regions of the domain, e.g. fuel assemblies; and the use of the non-standard spectral Green's function (SGF) auxiliary equations in the non-multiplying regions of the domain, e.g., the reflector. In slab-geometry the hybrid SD-SGF method generates numerical results that are completely free of spatial truncation errors. In X,Y-geometry, we obtain a system of two 'slab-geometry' SN equations for the node-edge average angular fluxes by transverse-integrating the X,Y-geometry SN equations separately in the y- and then in the x-directions within an arbitrary node of the spatial grid set up on the domain. In this paper, we approximate the transverse leakage terms by constants. These are the only approximations considered in the SD-SGF-constant nodal method, as the source terms, that include scattering and eventually fission events, are treated exactly. We show numerical results to typical model problems to illustrate the accuracy of spectral nodal methods for coarse-mesh SN criticality calculations. (author)

    Full Text Available It is a crucial and difficult problem in railway transportation dispatch mechanism to automatically compile train operation adjustment (TOA plan with computer to ensure safe, fast, and punctual running of trains. Based on the proposed model of TOA under the conditions of railway network (RN, we take minimum travel time of train as objective function of optimization, and after fast preliminary evaluation calculation on it, we introduce the theory and method of ordinal optimization (OO to solve it. This paper discusses in detail the implementation steps of OO algorithm. A practical calculation example of Datong-Qinhuangdao (hereinafter referred to as Da-Qin heavy haul railway is performed with the proposed algorithm to prove that OO can ensure getting good enough solution with high probability. Particularly, for complex optimization problems with large amount of calculation, OO can greatly increase computational efficiency, and it can save at least one order of magnitude of calculation amount than general heuristic algorithm. Thus, the proposed algorithm can well satisfy the requirements in engineering.

    In order to explore this approach, a Co-ordinated Research Programme (CRP) on the Use of Isotope Studies for Increasing and Stabilizing Plant Productivity in Low Phosphate and Semi-arid and Sub-humid Soils of the Tropics and Sub-tropics was initiated in October 1989 and complete in October 1994. Almost half of the work carried out under this programme concentrated on water use efficiency and the rest on phosphate use efficiency. Egypt, Morocco and Tunisia focused on wheat; Nigeria and Sierra Leone on cowpea; Kenya, Sudan and the United Republic of Tanzania on nitrogen fixing trees such as Prosopis, Acacia and Gliricidia; and Viet Nam on rice. Experiments conducted in the field showed that there is a wealth of genetic diversity among the genotypes/provenances of crop and tree species in their capacity for uptake and use of phosphorus and water from soils limited in resources. Several elite genotypes/provenances were identified which are highly efficient in water or phosphate use. In a few cases, the high water use efficiency (or the high phosphorus use efficiency) feature was seen in the same genotype where the grain yield was also high. Morphological parameters responsible for making some genotypes superior in their capacity to use phosphorus or water have also been investigated. It is our hope that the findings reported in this publication will help agricultural scientists in the Member States, particularly in Africa, in their quest of finding solutions to problems of food security.

    Where fissile materials are being processed in quantities exceeding the minimum critical amounts, a radiation risk to workers arises from the possibility of criticality excursions. Despite the fact that techniques for preventing the occurende of such accidental excursions have reached very high standards it is generally agreed that the availability of suitable nuclear accident dosimetry (NAD) systems is very important. Following the recommendations of an Advisory Group meeting on NAD, the IAEA had established in 1969 an international coordinated research programme on NAD systems and elaborating standarized systems. A large number of research groups from 14 Member States throughout the world participated in this co-ordinated work. Since 1970 four international multilaboratory intercomparison experiments on NAD have been organized and the response of a variety of dosimeters examined in different neutron spectra under simulated accident conditions at Valduc (France), Oak Ridge (USA), Vinca (Yugoslavia) and Harwell (UK). The results achieved in these intercomparison studies show that NAD systems have been substantially improved and that several systems are available now in a number of laboratories throughout the world that perform within the criteria laid down by the initiating advisory group in 1969. A compendium of neutron leakage spectra has also been elaborated for facilitating the determination of dose from readings of detectors exposed to various neutron fields in criticality accidents

  18. Improving Your Exploratory Factor Analysis for Ordinal Data: A Demonstration Using FACTOR

    2014-06-01

    Full Text Available Exploratory factor analysis (EFA methods are used extensively in the field of assessment and evaluation. Due to EFA's widespread use, common methods and practices have come under close scrutiny. A substantial body of literature has been compiled highlighting problems with many of the methods and practices used in EFA, and, in response, many guidelines have been proposed with the aim to improve application. Unfortunately, implementing recommended EFA practices has been restricted by the range of options available in commercial statistical packages and, perhaps, due to an absence of clear, practical - how-to' demonstrations. Consequently, this article describes the application of methods recommended to get the most out of your EFA. The article focuses on dealing with the common situation of analysing ordinal data as derived from Likert-type scales. These methods are demonstrated using the free, stand-alone, easy-to-use and powerful EFA package FACTOR (http://psico.fcep.urv.es/utilitats/factor/, Lorenzo-Seva & Ferrando, 2006. The demonstration applies the recommended techniques using an accompanying dataset, based on the Big 5 personality test. The outcomes obtained by the EFA using the recommended procedures through FACTOR are compared to the default techniques currently available in SPSS.

    Aim of this retrospective study was to assess the capability of contrast-enhanced helical computerised tomography (CT) in sigmoid diverticulitis, especially relative to selection of the appropriate treatment. The findings of 41 patients were reviewed from 1998 to 1999 June. Contrast-enhanced helical CT is the imaging modality of choice in assessing mild or severe acute diverticulitis because it provides useful information for appropriate treatment planning in the emergency setting. This technique is most useful in questionable cases and in patients with suspected severe diverticulitis where a choice must be made between different treatment options. [Italian] Scopo di questo studio retrospettivo e' illustrare i molteplici aspetti radiologici della flogosi diverticolare sigmoidea con tomografia computerizzata (TC) spirale, con specifico riguardo alle implicazioni terapeutiche che scaturiscono dall'analisi e dal confronto dei reperti TC con i riscontri clinici e chirurgici. Sono analizzati e discussi i risultati dello studio di 41 pazienti consecutivi con diverticolite del sigma esaminati dal giugno del 1998 al giugno del 1999. La TC spirale ha fornito dettagli precisi sul danno anatomo-chirurgico dell'ansa e sulle strutture limitrofe coinvolte consentendo di differenziare la diverticolite lieve da quella grave. Il suo ruolo si configura nei pazienti critici difficilmente classificabili e nelle sospette diverticoliti gravi o complicate per la molteplicita' delle scelte terapeutiche.

  20. Local ordinances as an instrument of social exclusion: the regulation affecting the homeless is administrative law of the enemy

    Directory of Open Access Journals (Sweden)

    Eduardo Melero Alonso

    2017-03-01

    Full Text Available This paper discusses local ordinances, especially the so-called coexistence ordinances, to the extent they affect the daily activities of the homeless. There are three areas of regulation: the prohibition of begging; a ban on sleeping, washing and perform physiological needs in public spaces; and the prohibition of sorting through garbage. This regulation is subjected to a critical analysis, focusing on the fact that has an impact on the fundamental rights of the homeless. The basic parameters of control are the reserve of law and, above all, the principle of proportionality. The conclusion reached is that, in many cases, this regulation is not only illegal, it can also be included within the category Administrative Law of the enemy.

    2007-11-01

    Full Text Available This paper makes a discourse analysis of the Civic Ordinance of Barcelona, adopted by the City Hall of Barcelona-Spain in January of 2006, in order to typify and manage behaviour in the public spaces of the city. The textual corpuswe used for this analysis is the Ordinance project in its two versions. The Discourse Analysis methodology used in thisstudy has been proposed by different authors in this field (Martín Rojo, 2001; Parker, 1992; Potter & Wetherell, 1987;Van Dijk, 2003; Wetherell, 2001. Results point to the emergence of two kinds of discourses inside the text, as well as the strategies from which both discourses allow the construction of citizens’ identities as a new way of governability in the spaces of contemporary European cities.

    Tse, Doris B; Young, Bruce K

    2012-01-06

    If maternal atopy and environmental exposure affect prenatal Th cell development, the maternal and fetal immune systems should display common Th1/Th2 phenotypes. To test this hypothesis, we studied maternal and neonatal blood samples from mothers with total serum IgE ordinate IFN-γ production from paired maternal and fetal mononuclear cells, accompanied by co-ordinate increases in activated CD4+CD69+ cells that display the CCR4+Th2 and CXCR3+ Th1 phenotypes. Maternal and fetal CD4+CXCR3+ T cells were subsequently identified as the major producers of IFN-γ. The data established that a transplacental nexus exists during normal pregnancy and that fetal Th cell responses may be biased by the maternal immune system.

    Garcia, R.D.M.

    2015-01-01

    Highlights: • An improved 1-D model of 3-D particle transport in ducts is studied. • The cases of isotropic and directional incidence are treated with the ADO method. • Accurate numerical results are reported for ducts of circular cross section. • A comparison with results of other authors is included. • The ADO method is found to be very efficient. - Abstract: An analytical discrete-ordinates solution is developed for the problem of particle transport in ducts, as described by a one-dimensional model constructed with two basis functions. Two types of particle incidence are considered: isotropic incidence and incidence described by the Dirac delta distribution. Accurate numerical results are tabulated for the reflection probabilities of semi-infinite ducts and the reflection and transmission probabilities of finite ducts. It is concluded that the developed solution is more efficient than commonly used numerical implementations of the discrete-ordinates method.

  6. On the spectrum of the one-speed slab-geometry discrete ordinates operator in neutron transport theory

    International Nuclear Information System (INIS)

    Abreu, Marcos Pimenta de

    1998-01-01

    We describe a numerical method applied to the first-order form of one-speed slab-geometry discrete ordinates equations modelling time-independent neutron transport problems with anisotropic scattering, with no interior source and defined in a nonmultiplying homogeneous host medium. Our numerical method is concerned with the generation of the spectrum and of a vector basis for the null space of the one-speed slab-geometry discrete ordinates operator. Moreover, it allows us to overcome the difficulties introduced in previous methods by anisotropic scattering and by angular quadrature sets of high order. To illustrate the positive features of our numerical method, we present numerical results for one-speed slab-geometry neutron transport model problems with anisotropic scattering

  7. How can the co-ordinate transformation method of beam matching be extended to include separately labelled collimators?

    Science.gov (United States)

    Morgan-Fletcher, S; McKenzie, A L

    1996-03-01

    The problem of matching radiation beams was tackled by Siddon in 1980 using co-ordinate transformations. Since then, the need to distinguish between individual collimators in prescriptions of treatment set-up, brought about by the widespread use of 3-D treatment planning systems and asymmetric fields, as well as a reversal of the rotation sense in the turntable co-ordinate system proposed by the International Electrotechnical Commission, have made it necessary to revisit this particular problem. This paper builds upon Siddon's general equations for the particular case of matching beams, and derives expressions for calculating treatment-unit settings which may be used in a computer program without the need to perform matrix manipulation. The expression treat the individual collimator jaws separately.

    Existing quantities of substances pursuant to Annex II of the 12th Federal Emission Control Ordinance in furnaces or in fuel storage facilities do not present a general hazard for fireplaces fired with coal, wood, heavy and light fuel oil within the meaning of the Accident Ordinance. In case of a fire in a storage facility for black coal, brown coal, untreated wood, light and heavy fuel oil, a general hazard on account of the release of developed substances is obviously excluded. Dispersion calculations pursuant to VDI 3783 have shown that concentrations of beryllium, arsenic, nickel, cobalt and mercury compounds in the vicinity of the fire source are so small that a general hazard can be excluded.

    The structure of the title compound has been determined by single-crystal X-ray diffraction methods from diffractometer data and refined to a final R of 0.023. The compound crystallises in space group R3c with asub(hex) = 18.447(3), csub(hex) = 19.348(3) A, Z = 6. The uranium atom is co-ordinated to one chlorine (U-Cl 2.813 A) and six oxygen atoms (mean U-O 2.26 A); the co-ordination polyhedron can be described as a distorted monocapped trigonal antiprism or as a distorted monocapped octahedron. The anionic chlorines are more than 6.22 A from the uranium atoms. The results are discussed in relation to spectral data for this and related uranium(IV) complexes. (author)

    Harris, N. R. P.; Carpenter, L.

    2014-12-01

    We present an overview of the main field activities of the UK CAST (Co-ordinated Airborne Studies in the Tropics) campaign, which took place in the West Pacific in January/February 2014. The aim was to study the processes that influence the Tropical Tropopause layer (TTL), the major route for troposphere to stratosphere transport. The field campaign was based mainly in Guam (13.5oN, 144.8oE) and had three components: the ATTREX project organized by NASA and based around the Global Hawk; the NCAR-led CONTRAST campaign based around the Gulfstream V (HIAPER) aircraft; and CAST with the NERC FAAM BAe-146 research aircraft. Together, the three aircraft were able to make detailed measurements of atmospheric structure and composition from the ocean surface to 20 km. The BAe-146 made a total of 25 flights between 1 oS-14 oN and 130 - 155 oE. The 146 was used to sample at low altitudes (below 8 km) with much of the time spent in or close to the marine boundary layer. This strategy meant that the region of main inflow into the strong convection was sampled thoroughly. Concentrations of the following chemicals were measured in situ: CO, O3, NO2, NO, CO2, CH4, N2O, H2O, a range of halocarbons including CH2Br2, CHBr3 and CH3I; and reactive halogen species including BrO, BrCl, HOBr and IO. The CAST team also made ground-based measurements at the ARM site on Manus Island in Papua New Guinea during February 2014. Ozonesondes were deployed daily, and measurements of ozone, CH4, CO, CO2, H2O and halocarbons were made at the ground. Halocarbon measurements were also made at other West Pacific sites.

  4. Ordination of breeding birds in relation to environmental gradients in three southeastern United States floodplain forests

    2007-01-01

    We used an ordination approach to identify factors important to the organization of breeding bird communities in three floodplains: Cache River, Arkansas (AR), Iatt Creek, Louisiana (LA), and the Coosawhatchie River, South Carolina (SC), USA. We used 5-min point counts to sample birds in each study area each spring from 1995 to 1998, and measured ground-surface elevations and a suite of other habitat variables to investigate bird distributions and community characteristics in relation to important environmental gradients. In both AR and SC, the average number of Neotropical migrant species detected was lowest in semipermanently flooded Nyssa aquatica Linnaeus habitats and greatest in the highest elevation floodplain zone. Melanerpes carolinus Linnaeus, Protonotaria citrea Boddaert, Quiscalus quiscula Linnaeus, and other species were more abundant in N. aquatica habitats, whereas Wilsonia citrina Boddaert, Oporornis formosus Wilson, Vireo griseus Boddaert, and others were more abundant in drier floodplain zones. In LA, there were no significant differences in community metrics or bird species abundances among forest types. Canonical correspondence analyses revealed that structural development of understory vegetation was the most important factor affecting bird distributions in all three study areas; however, potential causes of these structural gradients differed. In AR and SC, differences in habitat structure were related to the hydrologic gradient, as indexed by ground-surface elevation. In LA, structural variations were related mainly to the frequency of canopy gaps. Thus, bird communities in all three areas appeared to be organized primarily in response to repeated localized disturbance. Our results suggest that regular disturbance due to flooding plays an important role in structuring breeding bird communities in floodplains subject to prolonged inundation, whereas other agents of disturbance (e.g., canopy gaps) may be more important in headwater systems

    2017-10-01

    Recent studies suggest the importance of distinguishing severity levels of disability. Nevertheless, there is not yet a consensus with regards to an optimal classification. Our study seeks to advance the existing binary definitions towards categorical/ordinal manifestations of disability. We define disability according to the WHO's International Classification of Functioning, Disability and Health (ICF) using data collected at the baseline wave of the English Longitudinal Study of Aging, a longitudinal study of the non-institutionalized population, living in England. First, we identify cut-off points in the continuous disability score derived from ICF to distinguish disabled from no-disabled participants. Then, we fit latent class models to the same data to find the optimal number of disability classes according to: (i) model fit indicators; (ii) estimated probabilities of each disability item; (iii) association of the predicted disability classes with observed health and mortality. According to the binary classification criteria, about 32% of both men and women are classified disabled. No optimal number of classes emerged from the latent class models according to model fit indicators. However, the other two criteria suggest that the best-fitting model of disability severity has four classes. Our findings contribute to the debate on the usefulness and relevance of adopting a finer categorization of disability, by showing that binary indicators of disability averaged the burden of disability and masked the very strong effect experienced by individuals having severe disability, and were not informative for low levels of disability.

  6. DiagTest3Grp: An R Package for Analyzing Diagnostic Tests with Three Ordinal Groups

    Directory of Open Access Journals (Sweden)

    Jingqin Luo

    2012-10-01

    Full Text Available Medical researchers endeavor to identify potentially useful biomarkers to develop marker-based screening assays for disease diagnosis and prevention. Useful summary measures which properly evaluate the discriminative ability of diagnostic markers are critical for this purpose. Literature and existing software, for example, R packages nicely cover summary measures for diagnostic markers used for the binary case (e.g., healthy vs. diseased. An intermediate population at an early disease stage usually exists between the healthy and the fully diseased population in many disease processes. Supporting utilities for three-group diagnostic tests are highly desired and important for identifying patients at the early disease stage for timely treatments. However, application packages which provide summary measures for three ordinal groups are currently lacking. This paper focuses on two summary measures of diagnostic accuracy—volume under the receiver operating characteristic surface and the extended Youden index, with three diagnostic groups. We provide the R package DiagTest3Grp to estimate, under both parametric and nonparametric assumptions, the two summary measures and the associated variances, as well as the optimal cut-points for disease diagnosis. An omnibus test for multiple markers and a Wald test for two markers, on independent or paired samples, are incorporated to compare diagnostic accuracy across biomarkers. Sample size calculation under the normality assumption can be performed in the R package to design future diagnostic studies. A real world application evaluating the diagnostic accuracy of neuropsychological markers for Alzheimer’s disease is used to guide readers through step-by-step implementation of DiagTest3Grp to demonstrate its utility.

    Recently, several light receptors have been identified in non-phototrophic bacteria, but their physiological roles still remain rather elusive. Here we show that colonies of the saprophytic bacterium Listeria monocytogenes undergo synchronized multicellular behaviour on agar plates, in response to oscillating light/dark conditions, giving rise to alternating ring formation (opaque and translucent rings). On agar plates, bacteria from opaque rings survive increased levels of reactive oxygen species (ROS), as well as repeated cycles of light and dark, better than bacteria from translucent rings. The ring formation is strictly dependent on a blue-light receptor, Lmo0799, acting through the stress-sigma factor, σ(B) . A transposon screening identified 48 mutants unable to form rings at alternating light conditions, with several of them showing a decreased σ(B) activity/level. However, some of the tested mutants displayed a varied σ(B) activity depending on which of the two stress conditions tested (light or H(2) O(2) exposure). Intriguingly, the transcriptional regulator PrfA and the virulence factor ActA were shown to be required for ring formation by a mechanism involving activation of σ(B) . All in all, this suggests a distinct pathway for Lmo0799 that converge into a common signalling pathway for σ(B) activation. Our results show that night and day cycles co-ordinate a reversible differentiation of a L. monocytogenes colony at room temperature, by a process synchronized by a blue-light receptor and σ(B) . © 2013 Blackwell Publishing Ltd.

    Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed 'top-down' role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. Copyright © 2017.

    The aim of this study was to determine if it would be possible to use spinal bone single photon emission computed tomography (SPECT) in patients with unexplained back pain in varied clinical backgrounds and to determine if a positive or negative study had any prognostic value. The study was co-ordinated by the International Atomic Energy Agency (IAEA) and involved 8 centres in 7 countries. A total of 174 patients (mean age 42 years, range 15-80 years) were screened and found to have no obvious cause for their back pain at the time of the SPECT scan. All patients had a CT, and planar radiology. There was clinical follow-up data for 6 months without active treatment (such as surgery) in 147 patients. A panel of 9 specialists in nuclear medicine, radiology and orthopaedics reviewed all images and histories. Final assessment determined that 141 patients had skeletal causes for their back pain. SPECT was abnormal in 64% of these patients as compared to 58% with CT and 18% with planar radiology. CT was most likely to be diagnostic in disc degeneration (sensitivity 92%). SPECT was most diagnostic in facet joint disease (sensitivity 96%). In the 43 patients without any skeletal disease the specificity of SPECT was 79%, compared to 65% for CT. Follow-up of patients at 6 months showed that on average 71% had improvement of symptoms, suggesting a benign course for their back pain, with the exception of patients with pure facet joint disease, identified on SPECT but with no treatment. Spinal skeletal SPECT can be applied in a wide range of social and clinical settings. Results compare well with CT, providing additional information in 30% of patients, especially in facet joint disease where a positive SPECT study, suggests a worse clinical outcome at 6 months.

    Full Text Available Background: Birth weight is an important health parameter for obstetricians and gynaecologists. It is a good health indicator of a child-bearing mother and a strong predictor of infant morbidity and mortality. Methods: This paper utilizes data on 28,647 children born between 2003–2008 obtained from the 2008 Nigeria Demographic and Health Survey (NDHS. For a simple epidemiological convenience, the occurrence of a newborn weight can intuitively be considered to be categorical in nature and the thresholds can be put on a continuous scale. In survey reporting, the mothers frequently estimate their infant’s birth weight and make a classification in ordinal category (low, normal, large instead of actual birth weight. The study fits a multinomial regression model to analyze the relationships between the polytomous response and different kind of covariates in a unified manner. We estimate the fixed effects of bio-social covariates parametrically and the non-linear effect modeled using P-spline. The spatial component was modeled using conditional autoregressive error. A penalized maximum likelihood estimation was performed to estimate the model parameters. Results: We found risk factors that are positively associated with low birth weight, which include multiple birth, short birth interval, death of sibling, childhood diarrhea, fever, mother’s smoking, firewood/dung cooking and poor household. Results further showed that iron syrup supplementation, antenatal attendance, mother literacy and household wealth had significant association with low probability of low birth weight. The finding also showed spatial patterns, which are not captured by the underlying determinants, and we produced probability predictive maps of the spatial residual effects. Conclusions: In addition to the statistical relevance of our method, the generated spatial maps identify highly endemic areas of low birth weight that can assist government agency to channel scarce health

    The Research Coordination Meeting was held in Mito City, Japan on October 17-21, 1988, inviting the chief investigating scientists from 11 RCA member countries to discuss practical plans for the Coordinated Research Program (CRP) on 'Compilation of Anatomical, Physiological and Metabolic Characteristics for a Reference Asian Man' based on the decision taken at the Project Formulation Meeting for the RCA Project 'Strengthening Radiation Protection' Tokyo, November 1987. Significance of the setting 'Reference Man' for Asian peoples to estimate more realistic radiation doses by applying the real typical physical, physiological and metabolic parameters for them instead of those recommended by ICRP based on the data for 'Caucasian Man' has been indicated by whole member countries and recognized again at the Meeting. The present status of 'Reference Man-oriented Studies' in each countries was presented by the participants and certain difference or difficulties were pointed out among the countries depending on the geographical, social, or economical conditions as well as the ethnic circumstances. After the mutual discussions and exchange of up-to-date information, the general conclusions were drawn as follows: acknowledging the importance of the CRP, research works should be carried out in each country with the expected supports from IAEA and other member countries. The first priority is given on the measurements of human physique (and internal organs) followed by the food consumption survey. Trace element analysis would be done by the countries where possible. The standard manual for data collection might be necessary. The establishments of Co-ordination Center or central body with data base and also subgroup systems are desirable to promote the CRP.

    Full Text Available In questa ricerca di senso fra la fine di un'epoca e la nuova visione del mondo, c’è, nei due Autori, quello che potrebbe chiamarsi una betweenness: Pareto, quasi un franco-italiano, e Michels, un italiano-tedesco, anzi un più che italiano. Nella linea di faglia rappresentata dal primo conflitto mondiale, i due sociologi sono in una doppia relazione interiore appunto franco-italiana Pareto e italo-tedesca Michels e una relazione esteriore fra il mondo di ieri e il mondo successivo al cataclisma che fu la prima guerra mondiale, quando ben quattro imperi colossali erano stati smembrati (l’Impero Russo, l’Impero Tedesco, l’Impero Austro-ungarico e l’Impero ottomano, nello stesso tempo in cui Emile Durkheim guardava con inquietudine alla disgregazione delle vecchie comunità tradizionali, dove il senso della crisi del tempo investe non solo le persone e i comportamenti, ma il mondo logico stesso. Lo scambio epistolare avviene nella stessa terra: Pareto a Celigny, sul lago di Ginevra , e Michels a Basilea , lungo le rive del Reno. Vi è, fra i due sociologi un profondo rispetto, che vedrà Robert Michels dedicare allo “scienziato e amico Vilfredo Pareto con venerazione” un’opera importante come “Problemi di sociologia applicata” pubblicata solo tre anni dopo il Trattato di Sociologia Generale del Maestro. In questa antologia di saggi Robert Michels, probabilmente composti fra il 1914 e il 1917, negli anni del grande cataclisma, anzi concepiti prima «dell’insediamento di questa terribile corte suprema di cassazione di tutte le nostre ideologie, che è la guerra» , quindi contemporanea al Trattato, il Maestro viene citato tre volte, come Max Weber, ma, de facto, la presenza di Pareto è continua. In particolare, il richiamo al Maestro è iscritto a due piste di ricerca: da una parte la realtà della ricerca sociologica e del suo amplissimo spettro di analisi e dall’altra la teoria della circolazione delle elités.

  16. Nuclear based technologies for estimating microbial protein supply in ruminant livestock. Proceedings of the second research co-ordination meeting of a co-ordinated research project (phase 1)

    International Nuclear Information System (INIS)

    1999-06-01

    The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture through its Co-ordinated Research Projects (CRPs), has been assisting national agricultural research systems in Member States to develop and apply nuclear and related techniques for improving livestock productivity. The programmes have focused on animal nutrition, animal reproduction and more recently on animal nutrition/reproduction interactions with emphasis on smallholder farming systems. The measurement of microbial protein supply to ruminant livestock has been an important area of research in ruminant nutrition. An estimate of microbial protein contribution to the intestinal protein flow is important for estimating the protein requirement of ruminant animals. Understanding the process of microbial protein synthesis has been difficult however, and due to the lack of simple and accurate methods for measuring microbial protein production in vivo, the methods used are based on complex microbial markers which require surgically prepared animals. As a result of a consultants meeting held in May 1995 to advise the Joint FAO/IAEA Division on the feasibility of using nuclear and related techniques for the development and validation of techniques for measuring microbial protein supply in ruminant animals, an FAO/IAEA Co-ordinated Research Project on Development, Standardization and Validation of Nuclear Based Technologies for Measuring Microbial Protein Supply in Ruminant Livestock for Improving Productivity was initiated in 1996, with a view to validating and adapting this technology for use in developing countries. To assist scientists participating in the CRP, a laboratory manual containing experimental protocols and methodologies for standardization and validation of the urine purine derivative technique and the development of models to suit local conditions, was published as IAEA-TECDOC-945. The present publication contains the final reports from participants in Phase 1 of the project

  17. Macchina mitologica e machine célibataire: sulla rappresentazione del desiderio celibe nella letteratura francese del XIX secolo

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Questa riflessione sul mito sotteso alla «macchina celibe», teorizzata da Carrouges in Les Machines Célibataires, poi ripresa da Deleuze e Guattari in L’AntiOEdipe, si pone nella prospettiva di tracciare un collegamento con il modello ideato da Jesi di «macchina mitologica» – produttrice di «epifanie di miti». La prima progettazione di una macchina celibe nasce con l’opera di Duchamp, ed è da questa che Carrouges avvia la sua analisi, studiandone la qualità mitica e il meccanismo che la governa, per poi identificarla in alcuni esempi letterari otto e novecenteschi come L’Éve future di Villiers de l’Isle-Adam o Nella colonia penale di Kafka, in cui sono presenti le descrizioni di macchine prodigiose senza uno scopo sociale. Per Carrouges, «l’invariant fondamental du mythe des machines célibataires est la distance ou différence entre la machine et la solitude humaine»; la sua lettura della macchina celibe – mito moderno – considera l’uomo alle prese con la meccanica realtà novecentesca, rispetto alla quale il celibato assume una funzione non tesa alla produzione. La macchina celibe è caratterizzata da un godimento fine a se stesso e il suo «movimento oggettivo apparente» rassomiglia al «movimento in cerchio» della macchina mitologica jesiana. Deleuze e Guattari adottano la definizione di Carrouges e oppongono la macchina celibe alle macchine desideranti: ovvero l’improduttività del celibe alla motrice incessante del desiderio che produce desiderio, da essi posta alla base del processo capitalistico. Nella rappresentazione del celibato in alcuni case studies della letteratura francese del XIX secolo, verranno ricercate alcune tracce di questo mito moderno. The article proposes an analysis of the machine célibataire, theorized by M. Carrouges and then resumed by G. Deleuze and F. Guattari in L’AntiOEdipe, in order to define its relationship with the concept of Mythological machine introduced by Furio Jesi

    Full Text Available The objectives are to review results and experiences from interdisciplinary research projects in Research Centre for the Management of Animal Production and Health (CEPROS concerning scientific content, organisation, and collaboration. The Centre has been founded as a result of an agreement between four institutions: the Danish Institute of Agricultural Sciences (DIAS, the Danish Veterinary Laboratory (DVL, the Danish Veterinary Institute for Virus Research (DVIV and The Royal Veterinary and Agricultural University (KVL. CEPROS is a "research centre without walls" and is physically located as an integrated part of the four institutions named above. The Centre has close collaboration with the industry. The superior goals of the Centre are to co-ordinate fundamental and applied research and simultaneously integrate the veterinary and the production oriented livestock research within animal health and welfare, taking into consideration the production economics and reduced use of medication. The assignment of the Centre is to initiate and carry out research, aiming to investigate the influence of breeding and production systems on animal health and welfare as well as on production and product quality. The Centre has since 1997 established 16 interdisciplinary research projects dealing with cattle, pigs, poultry, or mink. The scientific content can be divided into three research clusters: A. Management of animal production and health in production systems, B: Pathogenesis of production diseases, and C. Animal health economics. In Cluster A, the physical environments of production systems have been investigated, broader definitions of the concept health have been established and used in identification of risk factors. Cluster B has investigated physiological, immunological and genetic mechanisms behind development of production diseases and how to apply this knowledge in disease prevention. The cluster in animal health economics has developed decision
