    Full Text Available Introduction and objective: To describe, analyze, and critically review the methodology employed in dental epidemiological research available on electronic databases, evaluating their structures according to Strobe and Consort initiative. Material and methods: ISI Web of knowledge, Scopus, and Pubmed electronic databases were selected for literature research, gathering publications in dental epidemiological area using the following designs: cross-sectional, cohort, case-control, descriptive, experimental, and quasi-experimental. Subsequently, five specific dentistry journals were selected and had their abstracts content analyzed under Strobe and Consort statement criterion. Results: From a universe of 10,160 articles from Pubmed (the greatest number, only 3,198 could be classified according to their epidemiological design by the electronic database searching tool. The most common designs were cross-sectional, cohort, case-control, descriptive, experimental and quasi-experimental publications, showing a tendency towards occurring bias and confounding factors in literature research due to missing words in papers structure. Even though Consort and Strobe initiatives have been accomplished since 2001 and 2004 respectively, some publications are not suitable for their checklist. Conclusion: Consort and Strobe statements must be strengthened by dental journals, editors and reviewers to improve the quality of the studies, attempting to avoid any sort of bias or confounding factors in the literature research performed by electronic database.

    During the period 1931–1939, Roşca described 13 spider species. To date, five species names have been synonymised. We propose that six species should be treated as nomina dubia because of their poor descriptions and lack of availability of types and/or other specimens. For two of Roşca’s species, Pardosa roscai (Roewer, 1951 and Tetragnatha reimoseri (Roşca, 1939, data and figures are presented and information on them is updated.

    Simpson, Serge-Emile

    2011-02-01

    A bezoar is a concretion of foreign material that forms and persists in the gastrointestinal tract. Bezoars are classified by their material origins. Phytobezoars contain plant material, trichobezoars contain hair, lactobezoars contain milk proteins, and pharmacobezoars contain pharmaceutical products. Tablets, suspensions, and even insoluble drug delivery vehicles can, on rare occasions, and sometimes under specific circumstances, form pharmacobezoars. The goal of this review is to catalog and examine all of the available reports in the English language medical literature that convincingly describe the formation and management of pharmacobezoars. Articles included in this review were identified by performing searches using the terms "bezoar," "pharmacobezoar," and "concretion" in the following databases: OVID MEDLINE, PubMed, and JSTOR. The complete MEDLINE and JSTOR holdings were included in the search without date ranges. The results were limited to English language publications. Articles that described nonmedication bezoars were not included in the review. Articles describing phytobezoars, food bezoars, fecal impactions, illicit drug packet ingestions, enteral feeding material bezoars, and hygroscopic diet aid bezoars were excluded. The bibliographic references within the articles already accumulated were then examined in order to gather additional pharmacobezoar cases. The cases are grouped by pharmaceutical agent that formed the bezoar, and groupings are arranged in alphabetical order. Discussions and conclusions specific to each pharmaceutical agent are included in that agent's subheading. Patterns and themes that emerged in the review of the assembled case reports are reviewed and presented in a more concise format. Pharmacobezoars form under a wide variety of circumstances and in a wide variety of patients. They are difficult to diagnose reliably. Rules for suspecting, diagnosing, and properly managing a pharmacobezoar are highly dependent on the

    2008-01-01

    Since the first Lazarus Project calculations, it has been frequently noted that binary black hole merger waveforms are 'simple.' In this talk we examine some of the simple features of coalescence and merger waveforms from a variety of binary configurations. We suggest an interpretation of the waveforms in terms of an implicit rotating source. This allows a coherent description, of both the inspiral waveforms, derivable from post-Newtonian(PN) calculations, and the numerically determined merger-ringdown. We focus particularly on similarities in the features of various Multipolar waveform components Generated by various systems. The late-time phase evolution of most L these waveform components are accurately described with a sinple analytic fit. We also discuss apparent relationships among phase and amplitude evolution. Taken together with PN information, the features we describe can provide an approximate analytic description full coalescence wavefoRms. complementary to other analytic waveforns approaches.

  14. Identifying and Describing the Impact of Cyclone, Storm and Flood Related Disasters on Treatment Management, Care and Exacerbations of Non-communicable Diseases and the Implications for Public Health.

    Over the last quarter of a century the frequency of natural disasters and the burden of non-communicable diseases (NCD) across the globe have been increasing. For individuals susceptible to, or chronically experiencing, NCDs this has become a significant risk. Disasters jeopardize access to essential treatment, care, equipment, water and food, which can result in an exacerbation of existing conditions or even preventable death. Consequently, there is a need to expand the public health focus of disaster management to include NCDs. To provide a platform for this to occur, this article presents the results from a systematic review that identifies and describes the impact of cyclone, flood and storm related disasters on those susceptible to, or experiencing, NCDs. The NCDs researched were: cardiovascular diseases; cancers; chronic respiratory diseases; and diabetes.   Four electronic publication databases were searched with a date limit of 31 December 2014. The data was analyzed through an aggregation of individual papers to create an overall data description. The data was then grouped by disease to describe the impact of a disaster on treatment management, exacerbation, and health care of people with NCDs. The PRISMA checklist was used to guide presentation of the research.   The review identified 48 relevant articles. All studies represented developed country data. Disasters interrupt treatment management and overall care for people with NCDs, which results in an increased risk of exacerbation of their illness or even death. The interruption may be caused by a range of factors, such as damaged transport routes, reduced health services, loss of power and evacuations. The health impact varied according to the NCD. For people with chronic respiratory diseases, a disaster increases the risk of acute exacerbation. Meanwhile, for people with cancer, cardiovascular diseases and diabetes there is an increased risk of their illness exacerbating, which can result in death

    2016-02-16

    Mass spectrometry Matrix-Assisted Laser Desorption-Ionization Time-of-Flight (MALDI-TOF) helps in the rapid identification of microorganisms causing blood stream infection. Rapid and reliable methods are required to decrease the turnaround time for reporting antimicrobial susceptibility results from blood culture isolates. An evaluation was performed on the reliability of a method for antimicrobial susceptibility testing of positive blood culture isolates from briefly incubated solid medium cultures. The agreement between the evaluated and standard methods was 99.3%. The major and minor error rates were 0.4% and 0.3%, respectively, and no very major errors were observed. The inoculation of briefly incubated solid medium cultures into antimicrobial susceptibility testing panels is an easy and reliable technique, and helps to decrease the turnaround time for reporting antimicrobial susceptibility results of positive blood cultures.

  16. How Mathematics Describes Life

    2017-01-01

    The circle of life is something we have all heard of from somewhere, but we don't usually try to calculate it. For some time we have been working on analyzing a predator-prey model to better understand how mathematics can describe life, in particular the interaction between two different species. The model we are analyzing is called the Holling-Tanner model, and it cannot be solved analytically. The Holling-Tanner model is a very common model in population dynamics because it is a simple descriptor of how predators and prey interact. The model is a system of two differential equations. The model is not specific to any particular set of species and so it can describe predator-prey species ranging from lions and zebras to white blood cells and infections. One thing all these systems have in common are critical points. A critical point is a value for both populations that keeps both populations constant. It is important because at this point the differential equations are equal to zero. For this model there are two critical points, a predator free critical point and a coexistence critical point. Most of the analysis we did is on the coexistence critical point because the predator free critical point is always unstable and frankly less interesting than the coexistence critical point. What we did is consider two regimes for the differential equations, large B and small B. B, A, and C are parameters in the differential equations that control the system where B measures how responsive the predators are to change in the population, A represents predation of the prey, and C represents the satiation point of the prey population. For the large B case we were able to approximate the system of differential equations by a single scalar equation. For the small B case we were able to predict the limit cycle. The limit cycle is a process of the predator and prey populations growing and shrinking periodically. This model has a limit cycle in the regime of small B, that we solved for

    Since the great policy of reform and opening which began in 1979 has turned up, an unprecedented vigorous development opportunity was brought for our domestic wine industry. On the one hand, the increasing in personal income level has stimulated the growth of wine consumption demand, leading to a nice development prospect for domestic wine industry;on the other hand, the dramatical y decreasing in tariff of importing wine is an undoubtedly major impact to the domestic wine industry. The competition between the enterprises is almost the same as the competition of marketing ability, the success of the marketing operation wil create rich profits resources for enterprises which wil lay a good foundation for enterprises to cultivate their ability and improve the core competitive ability. This article wil briefly analyze the marketing strategy of Changyu Group which is in the leading position of Chinese wine industry and provide the certain reference value for the same industry when they develop their own marketing strategy.

  19. Bringing color to emotion: The influence of color on attentional bias to briefly presented emotional images.

    2017-07-11

    Is color a critical feature in emotional content extraction and involuntary attentional orienting toward affective stimuli? Here we used briefly presented emotional distractors to investigate the extent to which color information can influence the time course of attentional bias in early visual cortex. While participants performed a demanding visual foreground task, complex unpleasant and neutral background images were displayed in color or grayscale format for a short period of 133 ms and were immediately masked. Such a short presentation poses a challenge for visual processing. In the visual detection task, participants attended to flickering squares that elicited the steady-state visual evoked potential (SSVEP), allowing us to analyze the temporal dynamics of the competition for processing resources in early visual cortex. Concurrently we measured the visual event-related potentials (ERPs) evoked by the unpleasant and neutral background scenes. The results showed (a) that the distraction effect was greater with color than with grayscale images and (b) that it lasted longer with colored unpleasant distractor images. Furthermore, classical and mass-univariate ERP analyses indicated that, when presented in color, emotional scenes elicited more pronounced early negativities (N1-EPN) relative to neutral scenes, than when the scenes were presented in grayscale. Consistent with neural data, unpleasant scenes were rated as being more emotionally negative and received slightly higher arousal values when they were shown in color than when they were presented in grayscale. Taken together, these findings provide evidence for the modulatory role of picture color on a cascade of coordinated perceptual processes: by facilitating the higher-level extraction of emotional content, color influences the duration of the attentional bias to briefly presented affective scenes in lower-tier visual areas.

  2. On Redundancy in Describing Linguistic Systems

    Directory of Open Access Journals (Sweden)

    Vladimir Borissov Pericliev

    2015-12-01

    Full Text Available On Redundancy in Describing Linguistic Systems The notion of system of linguistic elements figures prominently in most post-Saussurian linguistics up to the present. A “system” is the network of the contrastive (or, distinctive features each element in the system bears to the remaining elements. The meaning (valeur of each element in the system is the set of features that are necessary and jointly sufficient to distinguish this element from all others. The paper addresses the problems of “redundancy”, i.e. the occurrence of features that are not strictly necessary in describing an element in a system. Redundancy is shown to smuggle into the description of linguistic systems, this infelicitous practice illustrated with some examples from the literature (e.g. the classical phonemic analysis of Russian by Cherry, Halle, and Jakobson, 1953. The logic and psychology of the occurrence of redundancy are briefly sketched and it is shown that, in addition to some other problems, redundancy leads to a huge and unresolvable ambiguity of descriptions of linguistic systems (the Buridan’s ass problem.

    Science.gov (United States)

    Kalra, Gurvinder; Bhui, Kamaldeep; Bhugra, Dinesh

    2013-01-01

    Sikhism is a relatively young religion, with Guru Granth Sahib as its key religious text. This text describes emotions in everyday life, such as happiness, sadness, anger, hatred, and also more serious mental health issues such as depression and psychosis. There are references to the causation of these emotional disturbances and also ways to get out of them. We studied both the Gurumukhi version and the English translation of the Guru Granth Sahib to understand what it had to say about depression, its henomenology, and religious prescriptions for recovery. We discuss these descriptions in this paper and understand its meaning within the context of clinical depression. Such knowledge is important as explicit descriptions about depression and sadness can help encourage culturally appropriate assessment and treatment, as well as promote public health through education.

    2012-01-01

    The diffusion of ideas is often closely connected to the creation and diffusion of knowledge and to the technological evolution of society. Because of this, knowledge creation, exchange and its subsequent transformation into innovations for improved welfare and economic growth is briefly described from a historical point of view. Next, three approaches are discussed for modeling the diffusion of ideas in the areas of science and technology, through (i) deterministic, (ii) stochastic, and (iii) statistical approaches. These are illustrated through their corresponding population dynamics and epidemic models relative to the spreading of ideas, knowledge and innovations. The deterministic dynamical models are considered to be appropriate for analyzing the evolution of large and small societal, scientific and technological systems when the influence of fluctuations is insignificant. Stochastic models are appropriate when the system of interest is small but when the fluctuations become significant for its evolution...

  3. Public Science: From Earth to the Solar System

    Science.gov (United States)

    Arcand, K. K.; Watzke, M.

    2012-09-01

    This talk will describe how the International Year of Astronomy (IYA2009) was used to launch a new initiative of science outreach, which the authors describe as "public science." The enormous scope and range of IYA2009 allowed From Earth to the Universe (FETTU) to reach millions of people around the globe by putting large-scale astronomical images into public and community-based settings such as parks, metro stations, libraries, and more. Currently, its derivative project, From Earth to the Solar System (FETTSS), continues the implementation of this public science paradigm. Public science projects, like FETTU and FETTSS, are very much akin to public art, which attempts to gain attention and expose large numbers of people to its content. Can such public science projects be used to increase exposure and awareness for STEM (science, technology, engineering, and mathematics) topics? This talk will briefly describe some of the measureable outcomes in this area found in FETTU, which have already been published in scholarly journals. We will also share some preliminary findings from new data being collected from FETTSS, as well as discuss other public science projects in development. The presenter will finally explore how this concept of public science may be useful for science communication efforts in the future.

  9. Quantum formalism to describe binocular rivalry.

    Science.gov (United States)

    Manousakis, Efstratios

    2009-11-01

    On the basis of the general character and operation of the process of perception, a formalism is sought to mathematically describe the subjective or abstract/mental process of perception. It is shown that the formalism of orthodox quantum theory of measurement, where the observer plays a key role, is a broader mathematical foundation which can be adopted to describe the dynamics of the subjective experience. The mathematical formalism describes the psychophysical dynamics of the subjective or cognitive experience as communicated to us by the subject. Subsequently, the formalism is used to describe simple perception processes and, in particular, to describe the probability distribution of dominance duration obtained from the testimony of subjects experiencing binocular rivalry. Using this theory and parameters based on known values of neuronal oscillation frequencies and firing rates, the calculated probability distribution of dominance duration of rival states in binocular rivalry under various conditions is found to be in good agreement with available experimental data. This theory naturally explains an observed marked increase in dominance duration in binocular rivalry upon periodic interruption of stimulus and yields testable predictions for the distribution of perceptual alteration in time.

  10. Dispersive models describing mosquitoes’ population dynamics

    Yamashita, W. M. S.; Takahashi, L. T.; Chapiro, G.

    2016-08-01

    The global incidences of dengue and, more recently, zica virus have increased the interest in studying and understanding the mosquito population dynamics. Understanding this dynamics is important for public health in countries where climatic and environmental conditions are favorable for the propagation of these diseases. This work is based on the study of nonlinear mathematical models dealing with the life cycle of the dengue mosquito using partial differential equations. We investigate the existence of traveling wave solutions using semi-analytical method combining dynamical systems techniques and numerical integration. Obtained solutions are validated through numerical simulations using finite difference schemes.

    2016-03-01

    Surgical pathology of the sinonasal region (i.e., nasal cavity and the paranasal sinuses) is notoriously difficult, due in part to the remarkable diversity of neoplasms that may be encountered in this area. In addition, a number of neoplasms have been only recently described in the sinonasal tract, further compounding the difficulty for pathologists who are not yet familiar with them. This manuscript will review the clinicopathologic features of some of the recently described sinonasal tumor types: NUT midline carcinoma, HPV-related carcinoma with adenoid cystic-like features, SMARCB1 (INI-1) deficient sinonasal carcinoma, biphenotypic sinonasal sarcoma, and adamantinoma-like Ewing family tumor.

  16. A Dualistic Model To Describe Computer Architectures

    Science.gov (United States)

    Nitezki, Peter; Engel, Michael

    1985-07-01

    The Dualistic Model for Computer Architecture Description uses a hierarchy of abstraction levels to describe a computer in arbitrary steps of refinement from the top of the user interface to the bottom of the gate level. In our Dualistic Model the description of an architecture may be divided into two major parts called "Concept" and "Realization". The Concept of an architecture on each level of the hierarchy is an Abstract Data Type that describes the functionality of the computer and an implementation of that data type relative to the data type of the next lower level of abstraction. The Realization on each level comprises a language describing the means of user interaction with the machine, and a processor interpreting this language in terms of the language of the lower level. The surface of each hierarchical level, the data type and the language express the behaviour of a ma-chine at this level, whereas the implementation and the processor describe the structure of the algorithms and the system. In this model the Principle of Operation maps the object and computational structure of the Concept onto the structures of the Realization. Describing a system in terms of the Dualistic Model is therefore a process of refinement starting at a mere description of behaviour and ending at a description of structure. This model has proven to be a very valuable tool in exploiting the parallelism in a problem and it is very transparent in discovering the points where par-allelism is lost in a special architecture. It has successfully been used in a project on a survey of Computer Architecture for Image Processing and Pattern Analysis in Germany.

    Stephenson, Pam Shockey; Berry, Devon M

    2015-09-01

    Spirituality is salient to persons nearing the end of life (EOL). Unfortunately, researchers have not been able to agree on a universal definition of spirituality reducing the effectiveness of spiritual research. To advance spiritual knowledge and build an evidence base, researchers must develop creative ways to describe spirituality as it cannot be explicitly defined. A literature review was conducted to determine the common attributes that comprise the essence of spirituality, thereby creating a common ground on which to base spiritual research. Forty original research articles (2002 to 2012) focusing on EOL and including spiritual definitions/descriptions were reviewed. Analysis identified five attributes that most commonly described the essence of spirituality, including meaning, beliefs, connecting, self-transcendence, and value.

  1. On Gaussian Beams Described by Jacobi's Equation

    CERN Document Server

    Smith, Steven Thomas

    2013-01-01

    Gaussian beams describe the amplitude and phase of rays and are widely used to model acoustic propagation. This paper describes four new results in the theory of Gaussian beams. (1) It is shown that the \\v{C}erven\\'y equations for the amplitude and phase are equivalent to the classical Jacobi Equation of differential geometry. The \\v{C}erven\\'y equations describe Gaussian beams using Hamilton-Jacobi theory, whereas the Jacobi Equation expresses how Gaussian and Riemannian curvature determine geodesic flow on a Riemannian manifold. Thus the paper makes a fundamental connection between Gaussian beams and an acoustic channel's so-called intrinsic Gaussian curvature from differential geometry. (2) A new formula $\\pi(c/c")^{1/2}$ for the distance between convergence zones is derived and applied to several well-known profiles. (3) A class of "model spaces" are introduced that connect the acoustics of ducting/divergence zones with the channel's Gaussian curvature $K=cc"-(c')^2$. The "model" SSPs yield constant Gauss...

  4. Public and private sector interactions: an economic perspective.

    Science.gov (United States)

    Maynard, A

    1986-01-01

    The debate about the public-private mix for health care has been dominated by rhetoric and the failure to evaluate the characteristics of the outcomes of public and private health care systems and to relate these to policy targets. After a brief analysis of the competing, liberal (conservative) and collectivist (socialist), objectives, the nature of the private health care sector in Britain is described and it is shown that growth has faltered due to cost containment problems. This outcome is the product of characteristics of the private health care system, paralleled precisely in the NHS: asymmetry information, monopoly power, moral hazard and third party pays. The final section discusses briefly some remedies for the inefficient and inequitable outcomes which are seen in all health care markets and it is argued that competition within public and private health care systems may enable each system type to achieve its own particular objectives more efficiently.

  7. Is an eclipse described in the Odyssey?

    Science.gov (United States)

    Baikouzis, Constantino; Magnasco, Marcelo O

    2008-07-01

    Plutarch and Heraclitus believed a certain passage in the 20th book of the Odyssey ("Theoclymenus's prophecy") to be a poetic description of a total solar eclipse. In the late 1920s, Schoch and Neugebauer computed that the solar eclipse of 16 April 1178 B.C.E. was total over the Ionian Islands and was the only suitable eclipse in more than a century to agree with classical estimates of the decade-earlier sack of Troy around 1192-1184 B.C.E. However, much skepticism remains about whether the verses refer to this, or any, eclipse. To contribute to the issue independently of the disputed eclipse reference, we analyze other astronomical references in the Epic, without assuming the existence of an eclipse, and search for dates matching the astronomical phenomena we believe they describe. We use three overt astronomical references in the epic: to Boötes and the Pleiades, Venus, and the New Moon; we supplement them with a conjectural identification of Hermes's trip to Ogygia as relating to the motion of planet Mercury. Performing an exhaustive search of all possible dates in the span 1250-1115 B.C., we looked to match these phenomena in the order and manner that the text describes. In that period, a single date closely matches our references: 16 April 1178 B.C.E. We speculate that these references, plus the disputed eclipse reference, may refer to that specific eclipse.

  8. Using neural networks to describe tracer correlations

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available Neural networks are ideally suited to describe the spatial and temporal dependence of tracer-tracer correlations. The neural network performs well even in regions where the correlations are less compact and normally a family of correlation curves would be required. For example, the CH4-N2O correlation can be well described using a neural network trained with the latitude, pressure, time of year, and methane volume mixing ratio (v.m.r.. In this study a neural network using Quickprop learning and one hidden layer with eight nodes was able to reproduce the CH4-N2O correlation with a correlation coefficient between simulated and training values of 0.9995. Such an accurate representation of tracer-tracer correlations allows more use to be made of long-term datasets to constrain chemical models. Such as the dataset from the Halogen Occultation Experiment (HALOE which has continuously observed CH4  (but not N2O from 1991 till the present. The neural network Fortran code used is available for download.

  10. Stimulated recall interviews for describing pragmatic epistemology

    Science.gov (United States)

    Shubert, Christopher W.; Meredith, Dawn C.

    2015-12-01

    Students' epistemologies affect how and what they learn: do they believe physics is a list of equations, or a coherent and sensible description of the physical world? In order to study these epistemologies as part of curricular assessment, we adopt the resources framework, which posits that students have many productive epistemological resources that can be brought to bear as they learn physics. In previous studies, these epistemologies have been either inferred from behavior in learning contexts or probed through surveys or interviews outside of the learning context. We argue that stimulated recall interviews provide a contextually and interpretively valid method to access students' epistemologies that complement existing methods. We develop a stimulated recall interview methodology to assess a curricular intervention and find evidence that epistemological resources aptly describe student epistemologies.

  11. A Semantic Approach to Describe Geospatial Resources

    Science.gov (United States)

    de Sousa, Sidney Roberto

    Geographic information systems (GIS) are increasingly using geospatial data from the Web to produce geographic information. One big challenge is to find the relevant data, which often is based on keywords or even file names. However, these approaches lack semantics. Thus, it is necessary to provide mechanisms to prepare data to help retrieval of semantically relevant data. This paper proposes an approach to attack this problem. This approach is based on semantic annotations that use geographic metadata and ontologies to describe heterogeneous geospatial data. Semantic annotations are RDF/XML files that rely on a FGDC metadata schema, filled with appropriate ontology terms, and stored in a XML database. The proposal is illustrated by a case study of semantic annotations of agricultural resources, using domain ontologies.

  12. Using default inheritance to describe LTAG

    CERN Document Server

    Evans, R; Weir, D; Evans, Roger; Gazdar, Gerald; Weir, David

    1995-01-01

    We present the results of an investigation into how the set of elementary trees of a Lexicalized Tree Adjoining Grammar can be represented in the lexical knowledge representation language DATR (Evans & Gazdar 1989a,b). The LTAG under consideration is based on the one described in Abeille et al. (1990). Our approach is similar to that of Vijay-Shanker & Schabes (1992) in that we formulate an inheritance hierarchy that efficiently encodes the elementary trees. However, rather than creating a new representation formalism for this task, we employ techniques of established utility in other lexically-oriented frameworks. In particular, we show how DATR's default mechanism can be used to eliminate the need for a non-immediate dominance relation in the descriptions of the surface LTAG entries. This allows us to embed the tree structures in the feature theory in a manner reminiscent of HPSG subcategorisation frames, and hence express lexical rules as relations over feature structures.

  13. Describing Ecosystem Complexity through Integrated Catchment Modeling

    Science.gov (United States)

    Shope, C. L.; Tenhunen, J. D.; Peiffer, S.

    2011-12-01

    Land use and climate change have been implicated in reduced ecosystem services (ie: high quality water yield, biodiversity, and agricultural yield. The prediction of ecosystem services expected under future land use decisions and changing climate conditions has become increasingly important. Complex policy and management decisions require the integration of physical, economic, and social data over several scales to assess effects on water resources and ecology. Field-based meteorology, hydrology, soil physics, plant production, solute and sediment transport, economic, and social behavior data were measured in a South Korean catchment. A variety of models are being used to simulate plot and field scale experiments within the catchment. Results from each of the local-scale models provide identification of sensitive, local-scale parameters which are then used as inputs into a large-scale watershed model. We used the spatially distributed SWAT model to synthesize the experimental field data throughout the catchment. The approach of our study was that the range in local-scale model parameter results can be used to define the sensitivity and uncertainty in the large-scale watershed model. Further, this example shows how research can be structured for scientific results describing complex ecosystems and landscapes where cross-disciplinary linkages benefit the end result. The field-based and modeling framework described is being used to develop scenarios to examine spatial and temporal changes in land use practices and climatic effects on water quantity, water quality, and sediment transport. Development of accurate modeling scenarios requires understanding the social relationship between individual and policy driven land management practices and the value of sustainable resources to all shareholders.

  14. Describing and Enhancing Collaboration at the Computer

    Directory of Open Access Journals (Sweden)

    Ken Beatty

    2002-06-01

    Full Text Available Computer-based learning materials differ from classroom practice in that they seldom explicitly offer opportunities for collaboration. Despite this, students do collaborate, helping one another through the content and affordances of computer materials. But, in doing so, students meet with challenges. Paradoxically, these challenges can either inspire or discourage learning and second-language acquisition. This paper, based on research with twenty Hong Kong university students in a controlled experiment, evaluates challenges to collaboration at the computer as evidenced by discourse. The students were videotaped and their discourse transcribed and evaluated both qualitatively and quantitatively, according to a set of discourse markers created to describe collaborative, non-collaborative and ambiguous strategies. The paper begins by exploring the differences between collaboration and similar terms such as teamwork and cooperative learning then goes on to define collaboration in the context of computer-assisted learning. It ends by presenting practical suggestions for software designers, teachers and students to enhance collaboration at the computer.

  15. Plans should abstractly describe intended behavior

    Energy Technology Data Exchange (ETDEWEB)

    Pfleger, K.; Hayes-Roth, B. [Stanford Univ., CA (United States)

    1996-12-31

    Planning is the process of formulating a potential course of action. How courses of action (plans) produced by a planning module are represented and how they are used by execution-oriented modules of a complex agent to influence or dictate behavior are critical architectural issues. In contrast to the traditional model of plans as executable programs that dictate precise behaviors, we claim that autonomous agents inhabiting dynamic, unpredictable environments can make better use of plans that only abstractly describe their intended behavior. Such plans only influence or constrain behavior, rather than dictating it. This idea has been discussed in a variety of contexts, but it is seldom incorporated into working complex agents. Experiments involving instantiations of our Adaptive Intelligent Systems architecture in a variety of domains have demonstrated the generality and usefulness of the approach, even with our currently simple plan representation and mechanisms for plan following. The behavioral benefits include (1) robust improvisation of goal-directed behavior in response to dynamic situations, (2) ready exploitation of dynamically acquired knowledge or behavioral capabilities, and (3) adaptation based on dynamic aspects of coordinating diverse behaviors to achieve multiple goals. In addition to these run-time advantages, the approach has useful implications for the design and configuration of agents. Indeed, the core ideas of the approach are natural extensions of fundamental ideas in software engineering.

  16. Can the genetic code be mathematically described?

    Science.gov (United States)

    Gonzalez, Diego L

    2004-04-01

    From a mathematical point of view, the genetic code is a surjective mapping between the set of the 64 possible three-base codons and the set of 21 elements composed of the 20 amino acids plus the Stop signal. Redundancy and degeneracy therefore follow. In analogy with the genetic code, non-power integer-number representations are also surjective mappings between sets of different cardinality and, as such, also redundant. However, none of the non-power arithmetics studied so far nor other alternative redundant representations are able to match the actual degeneracy of the genetic code. In this paper we develop a slightly more general framework that leads to the following surprising results: i) the degeneracy of the genetic code is mathematically described, ii) a new symmetry is uncovered within this degeneracy, iii) by assigning a binary string to each of the codons, their classification into definite parity classes according to the corresponding sequence of bases is made possible. This last result is particularly appealing in connection with the fact that parity coding is the basis of the simplest strategies devised for error correction in man-made digital data transmission systems.

    The Community Action and Public Health study explored how Ontario public health practitioners interpret and implement guidance in community action. In-depth interviews were conducted with 107 public health professionals and community members in 6 Ontario health units. This report briefly describes the study methods and presents results pertaining to the measurement of success based on interviews with 67 public health professionals. Data substantiate the view that evaluation methodologies employing quantitative measures of epidemiological outcomes inadequately capture "success" in community action, possibly attributable to an unproductive dichotomization of "process" and "outcome". Results suggest two kinds of "success": a) changes related to stated goals and targets; and b) more iterative and process-oriented changes, including necessary but often undocumented shifts in relationships, structures, social conditions and processes. In order to legitimize and validate results that might otherwise pass unrecognized, we suggest a methodology that records project "milestones" as successes in their own right.

  1. Conceptual framework describing a child's total (built, natural ...

    Science.gov (United States)

    The complexity of the components and their interactions that characterize children’s health and well-being are not adequately captured by current public health paradigms. Children are exposed to combinations of chemical and non-chemical stressors from their built, natural, and social environments at each lifestage and throughout their lifecourse. Children’s inherent characteristics (e.g., sex, genetics, pre-existing disease) and their activities and behaviors also influence their exposures to chemical and non-chemical stressors from these environments. We describe a conceptual framework that considers the interrelationships between inherent characteristics, activities and behaviors, and stressors (both chemical and non-chemical) from the built, natural, and social environments in influencing children’s health and well-being throughout their lifecourse. This framework is comprised of several intersecting circles that represent how stressors from the total environment interact with children’s inherent characteristics and their activities and behaviors to influence their health and well-being at each lifestage and throughout their lifecourse. We used this framework to examine the complex interrelationships between chemical and non-chemical stressors for two public health challenges specific to children: childhood obesity and general cognitive ability. One systematic scoping review showed that children’s general cognitive ability was influenced not only by

    Direct regulation of public utility activity and behavior has been the predominant approach to protect the public interest in this country. Changes in technology, as well as new thinking about the optimum role of regulation, have created a changing atmosphere in all of the traditional public utility industries. Competitive markets for many of the products and services in these industries have been developing. While monopoly power will continue to exist in certain parts of these industries and require direct regulation, in many areas a growing reliance upon competition as the best method of serving the public interest is developing. With this shift in emphasis from regulation to free markets, the antitrust laws take on new importance for these industries. In the absence of direct regulator control, those laws are society`s primary method of insuring the markets necessary to make competition an effective device for protecting the public interest. This study provides an overview of the antitrust laws, briefly describes the applicable theoretical underpinnings, and then turns to areas where public utility activity may pose special problems or conflicts with prevailing antitrust policy.

    As part of the International Arctic Seas Assessment Project (IASAP) of the International Atomic Energy Agency (IAEA), a working group was created to model the dispersal and transfer of radionuclides released from radioactive waste disposed of in the Kara Sea. The objectives of this group are: (1) development of realistic and reliable assessment models for the dispersal of radioactive contaminants both within, and from, the Arctic ocean; and (2) evaluation of the contributions of different transfer mechanisms to contaminant dispersal and hence, ultimately, to the risks to human health and environment. With regard to the first objective, the modelling work has been directed towards assessment of model reliability and as one aspect of this, a benchmarking exercise has been carried out. This paper briefly describes the benchmark scenario, the models developed and used, and discusses some of the benchmarking results. The role of the exercise within the modelling programme of IASAP will be discussed and future work described.

    Following the Fukushima accident, the safety features of Nuclear Power Plants (NPP) are being re-examined worldwide including India to demonstrate capabilities to cope with severe accidents. In order to restore public confidence and support for nuclear power, it is felt necessary to design future NPPs with near zero impact outside the plant boundary and thus enabling elimination of emergency planning in public domain. Authors have identified a set of safety features which are needed to be incorporated in advanced reactors to achieve this goal. These features enabling prevention, termination, mitigation and containment of radioactivity for beyond design basis accidents arising from extreme natural events are essential for achieving the goal of elimination of emergency planning in public domain. Inherent safety characteristics, passive and engineered safety features to achieve these functions are discussed in this paper. Present trends and future developments in this direction are also described briefly.

  13. Strength in Numbers: Describing the Flooded Area of Isolated Wetlands

    Science.gov (United States)

    Lee, Terrie M.; Haag, Kim H.

    2006-01-01

    Thousands of isolated, freshwater wetlands are scattered across the karst1 landscape of central Florida. Most are small (less than 15 acres), shallow, marsh and cypress wetlands that flood and dry seasonally. Wetland health is threatened when wetland flooding patterns are altered either by human activities, such as land-use change and ground-water pumping, or by changes in climate. Yet the small sizes and vast numbers of isolated wetlands in Florida challenge our efforts to characterize them collectively as a statewide water resource. In the northern Tampa Bay area of west-central Florida alone, water levels are measured monthly in more than 400 wetlands by the Southwest Florida Water Management Distirct (SWFWMD). Many wetlands have over a decade of measurements. The usefulness of long-term monitoring of wetland water levels would greatly increase if it described not just the depth of water at a point in the wetland, but also the amount of the total wetland area that was flooded. Water levels can be used to estimate the flooded area of a wetland if the elevation contours of the wetland bottom are determined by bathymetric mapping. Despite the recognized importance of the flooded area to wetland vegetation, bathymetric maps are not available to describe the flooded areas of even a representative number of Florida's isolated wetlands. Information on the bathymetry of isolated wetlands is rare because it is labor intensive to collect the land-surface elevation data needed to create the maps. Five marshes and five cypress wetlands were studied by the U.S. Geological Survey (USGS) during 2000 to 2004 as part of a large interdisciplinary study of isolated wetlands in central Florida. The wetlands are located either in municipal well fields or on publicly owned lands (fig. 1). The 10 wetlands share similar geology and climate, but differ in their ground-water settings. All have historical water-level data and multiple vegetation surveys. A comprehensive report by Haag and

    2006-09-01

    Full Text Available Abstract Background Many systems for routine public health surveillance rely on centralized collection of potentially identifiable, individual, identifiable personal health information (PHI records. Although individual, identifiable patient records are essential for conditions for which there is mandated reporting, such as tuberculosis or sexually transmitted diseases, they are not routinely required for effective syndromic surveillance. Public concern about the routine collection of large quantities of PHI to support non-traditional public health functions may make alternative surveillance methods that do not rely on centralized identifiable PHI databases increasingly desirable. Methods The National Bioterrorism Syndromic Surveillance Demonstration Program (NDP is an example of one alternative model. All PHI in this system is initially processed within the secured infrastructure of the health care provider that collects and holds the data, using uniform software distributed and supported by the NDP. Only highly aggregated count data is transferred to the datacenter for statistical processing and display. Results Detailed, patient level information is readily available to the health care provider to elucidate signals observed in the aggregated data, or for ad hoc queries. We briefly describe the benefits and disadvantages associated with this distributed processing model for routine automated syndromic surveillance. Conclusion For well-defined surveillance requirements, the model can be successfully deployed with very low risk of inadvertent disclosure of PHI – a feature that may make participation in surveillance systems more feasible for organizations and more appealing to the individuals whose PHI they hold. It is possible to design and implement distributed systems to support non-routine public health needs if required.

But how much do we teach and learn about how to lead, manage and care for our colleagues, our team members and ourselves? This paper emphasizes the need for leadership learning and teaching to become an essential element of the practice of public health. The paper presents the author’s perspective on the leadership skills required for public health and describes a five-day intensive course designed to enable participants to develop these skills over time. The paper briefly covers leadership definitions, styles and types and key leadership skills. It mainly focuses on the design and ethos of the course, skills self-assessment, group interaction and methods for developing and refining leadership skills. The course uses a collaborative learning approach where the power differential between teachers, facilitators, guests and participants is minimized. It is based on creating an environment where any participant can reveal his or her stories, successes, failures, preferences and dislikes in a safe manner. It encourages continual, constructive individual reflection, self-assessment and group interaction. The course is aimed at the practice of public health leadership, with a particular emphasis on the leadership of self, of knowing oneself, and of knowing and understanding colleagues retrospectively as well as prospectively. The most important outcome is the design and implementation of participants’ own plans for developing and nurturing their leadership skills.

  1. Recognition and memory for briefly presented scenes

    Directory of Open Access Journals (Sweden)

    Mary C ePotter

    2012-02-01

    Full Text Available Three times per second, our eyes make a new fixation that generates a new bottom-up analysis in the visual system. How much is extracted from each glimpse? For how long and in what form is that information remembered? To answer these questions, investigators have mimicked the effect of continual shifts of fixation by using rapid serial visual presentation (RSVP of sequences of unrelated pictures. Experiments in which viewers detect specified target pictures show that detection on the basis of meaning is possible at durations as brief as 13 ms, whereas memory for what was just seen is poor unless the viewer has about 500 ms to think about the scene: the scene does not need to remain in view. Initial memory loss after brief presentations occurs over several seconds, suggesting that at least some of the information from the previous few fixations persists long enough to support a coherent representation of the current environment. In contrast to marked memory loss shortly after brief presentations, memory for pictures viewed for 1 s or more is excellent. Although some specific visual information persists, the form and content of the perceptual and memory representations of pictures over time indicate that conceptual information is extracted early and determines most of what remains in longer term memory.

    Repetition priming in visual search has been a topic of extensive research since Maljkovic & Nakayama [1994, Memory & Cognition, 22, 657-672] presented the first detailed studies of such effects. Their results showed large reductions in reaction times when target color was repeated on consecutive...... pop-out search trials. Such repetition effects have since been generalized to a multitude of target attributes. Priming has primarily been investigated using self-terminating visual search paradigms, comparing differences in response times. Response accuracy has predominantly served as a control...... variable. Here we present results from experiments where position priming is demonstrated in paradigms involving temporally limited exposures to singleton targets.

  3. Intelligence for education: as described by Piaget and measured by psychometrics.

    Science.gov (United States)

    Shayer, Michael

    2008-03-01

    Two separate paths to the concept of intelligence are discussed: the psychometric path being concerned with the measurement of intelligence, involving the methodology of norm-referenced testing; the path followed by Piaget, and others, addresses from the start the related question of how intelligence can be described, and employs a criterion-referenced methodology. The achievements of psychometrics are briefly described, with an argument that they now remain important tools of what Kuhn called 'normal science'. The criterion-referenced approach of Piaget and others is described, with evidence from intervention studies that the Genevan descriptions of children-in-action have allowed the choice of contexts within which children can profitably be challenged to go further in their thinking. Hence, Genevan psychology is also now a part of the normal science with important uses, shown both in neo-Piagetian studies and further research stemming from Geneva. Discussion of the 'Flynn effect' sheds light on both paths, with problems still unresolved. The argument is then developed that the relevance of neuroscience needs to be discussed to try to decide in what ways it may provide useful insights into intelligence.

It is based on creating an environment where any participant can reveal his or her stories, successes, failures, preferences and dislikes in a safe manner. It encourages continual, constructive individual reflection, self-assessment and group interaction. The course is aimed at the practice of public health leadership, with a particular emphasis on the leadership of self, of knowing oneself, and of knowing and understanding colleagues retrospectively as well as prospectively. The most important outcome is the design and implementation of participants' own plans for developing and nurturing their leadership skills. Significance for public healthThe nature of public health is changing rapidly and increasing in complexity. These changes include major shifts in the burden of disease and the insatiable demands of clinical medicine swamping those of public health. Public health practitioners have failed over many years to systematically ensure that leadership and management skills are essential parts of public

    Federal public health advisors provide guidance and assistance to health departments to improve public health program work. The Centers for Disease Control and Prevention (CDC) prepares them with specialized training in administering public health programs. This article describes the evolving training and is based on internal CDC documents and interviews. The first federal public health advisors worked in health departments to assist with controlling syphilis after World War II. Over time, more CDC prevention programs hired them. To meet emerging needs, 3 major changes occurred: the Public Health Prevention Service, a fellowship program, in 1999; the Public Health Associate Program in 2007; and integration of those programs. Key components of the updated training are competency-based training, field experience, supervision, recruitment and retention, and stakeholder support. The enduring strength of the training has been the experience in a public health agency developing practical skills for program implementation and management.

  17. Neoliberal Policies and their Impact on Public Health Education: Observations on the Venezuelan Experience

    Directory of Open Access Journals (Sweden)

    Oscar Feo

    2008-11-01

    Full Text Available This article discusses the impact of neoliberal policies on the training of specialists in Public Health and describes the Venezuelan experience. In Venezuela, like other countries of the American continent, Public Health Schools had been transformed from institutions under the direction of the Ministry of Health to a model in which training took place under market conditions. Education in Public Health became a private good for individual consumption, and schools, lacking official funding, survived by offering courses in a market that did not necessarily respond to a country’s health needs. The conclusion discusses the currrent Venezuelan experience, in which the State has resumed control of the training of specialists in public health, making it more democratic, and adoptng an educational model centered around practice and whose purpose is the mass training of leadership teams to bolster the National Public Health System. In order to comment on the impact of neoliberal policies on training in public health we must first briefly review the following themes: 1. Basic concepts such as neoliberalism, globalization, and health systems. 2. The impact of neoliberal reforms on health. 3. The Venezuelan situation: basic principles for the training of professionals and technicians in health within the framework of a model of independent and sovereign national development. 4. Final reflections: challenges for the coming years.

    2005-01-01

    Describing Service-Oriented Architecture (SOA) is critical in the development of Web-based system. In this paper, an approach for describing SOA by extended Darwin is proposed. The requirements for describing SOA, which are different from that of ordinary architecture, are highlighted firstly, and then a solution for extending Darwin is presented. Using the extended Darwin, service components and connectors can be described explicit by the extended construct, as well as precise operational semantics of SOA by the π-calculus. Finally an example of supply-chain management system is given for manifesting the effect of the extended Darwin.

    The IAU Division C Commission 55, Communicating Astronomy with the Public, played an active role in Union affairs within Division C, Education, Outreach and Heritage. The International Astronomical Union (IAU) vested considerable responsibility for its public outreach efforts in Commission 55 (C55), Communicating Astronomy with the Public. This article briefly recounts the origin and history of C55 over the past decade, and describes the work of C55 until it became Division C Commission C.C2 in 2015. As stated on our website, http://www.communicatingastronomy.org, C55 was founded on the principle that ``it is the responsibility of every practising astronomer to play some role in explaining the interest and value of science to our real employers, the taxpayers of the world.'' While this was true a decade ago, when the Working Group that eventually became C55 first took shape, it is even more true today, when funding for the astronomical sciences (and science more generally) is under threat on nearly every continent.

    Crispin, Y.; Marduel, C. [Embry-Riddle Aeronautical Univ., Daytona Beach, FL (United States)

    1994-12-31

    The problem of suppressing chaotic behavior in dynamical systems is treated using a feedback control method with limited control effort. The proposed method is validated on archetypal systems described by maps, i.e. discrete-time difference equations. The method is also applicable to dynamical systems described by flows, i.e. by systems of ordinary differential equations. Results are presented for the one-dimensional logistic map and for a two-dimensional Lotka-Volterra map describing predator-prey population dynamics. It is shown that chaos can be suppressed and the system stabilized about a period-1 fixed point of the maps.

    Claude Francis Milliet Dechales described the Coriolis effect in his 1674 Cursus seu Mundus Mathematicus. Dechales discussed and illustrated the deflection of both falling bodies and of projectiles launched toward the poles that should occur on a rotating Earth. Interestingly, this was done as an argument against the Earth's rotation, the deflections not having been observed at the time. Dechales's work follows on that of Giovanni Battista Riccioli, who had also described the effect in his Almagestum Novum of 1651.

  12. Using public health and community partnerships to reduce density of alcohol outlets.

    Jernigan, David H; Sparks, Michael; Yang, Evelyn; Schwartz, Randy

    2013-04-11

    Excessive alcohol use causes approximately 80,000 deaths in the United States each year. The Guide to Community Preventive Services recommends reducing the density of alcohol outlets - the number of physical locations in which alcoholic beverages are available for purchase either per area or per population - through the use of regulatory authority as an effective strategy for reducing excessive alcohol consumption and related harms. We briefly review the research on density of alcohol outlets and public health and describe the powers localities have to influence alcohol outlet density. We summarize Regulating Alcohol Outlet Density: An Action Guide, which describes steps that local communities can take to reduce outlet density and the key competencies and resources of state and local health departments. These include expertise in public health surveillance and evaluation methods, identification and tracking of outcome measures, geographic information systems (GIS) mapping, community planning and development of multisector efforts, and education of community leaders and policy makers. We illustrate the potential for partnerships between public health agencies and local communities by presenting a contemporary case study from Omaha, Nebraska. Public health agencies have a vital and necessary role to play in efforts to reduce alcohol outlet density. They are often unaware of the potential of this strategy and have strong potential partners in the thousands of community coalitions nationwide that are focused on reducing alcohol-related problems.

  13. The coexistence of terms to describe the presence of multiple concurrent diseases

    Directory of Open Access Journals (Sweden)

    José Almirall

    2013-08-01

    Full Text Available Background: Consensus on terminology for multiple diseases is lacking. Because of the clinical relevance and social impact of multiple concurrent diseases, it is important that concepts are clear. Objective: To highlight the diversity of terms in the literature referring to the presence of multiple concurrent diseases/conditions and make recommendations. Design: A bibliometric analysis of English-language publications indexed in the MEDLINE database from 1970 to 2012 for the terms comorbidity, multimorbidity, polymorbidity, polypathology, pluripathology, multipathology, and multicondition, and a review of definitions of multimorbidity found in English-language publications indexed from 1970 to 2012 in the MEDLINE and SCOPUS databases. Results: Comorbidity was used in 67,557 publications, multimorbidity in 434, and the other terms in three to 31 publications. At least 144 publications used the term comorbidity without referring to an index disease. Thirteen general definitions of multimorbidity were identified, but only two were frequently used (91% of publications. The most frequently used definition (48% of publications was “more than one or multiple chronic or long-term diseases/conditions”. Multimorbidity was not defined in 51% of the publications using the term. Conclusions: Comorbidity was overwhelmingly used to describe any clinical entity coexisting with an index disease under study. Multimorbidity was the term most frequently used when no index disease was designated. Several definitions of multimorbidity were found. However, most authors using the term did not define it. The use of clearly defined terms in the literature is recommended until a general consensus on the terminology of multiple coexistent diseases is reached.

  14. Newly Described Components and Regulatory Mechanisms of Circadian Clock Function in Arabidopsis thaliana

    2012-01-01

    The circadian clock temporally coordinates plant growth and metabolism in close synchronization with the diurnal and seasonal environmental changes.Research over the last decade has identified a number of clock components and a variety of regulatory mechanisms responsible for the rhythmic oscillations in metabolic and physiological activities.At the core of the clock,transcriptional/translational feedback loops modulate the expression of a significant proportion of the genome.In this article,we briefly describe some of the very recent advances that have improved our understanding of clock organization and function in Arabidopsis thaliana.The new studies illustrate the role of clock protein complex formation on circadian gating of plant growth and identify alternative splicing as a new regulatory mechanism for clock function.Examination of key clock properties such as temperature compensation has also opened new avenues for functional research within the plant clockwork.The emerging connections between the circadian clock and metabolism,hormone signaling and response to biotic and abiotic stress also add new layers of complexity to the clock network and underscore the significance of the circadian clock regulating the daily life of plants.

    Gubrium, Aline C; Hill, Amy L; Flicker, Sarah

    2014-09-01

    This article explores ethical considerations related to participatory visual and digital methods for public health research and practice, through the lens of an approach known as "digital storytelling." We begin by briefly describing the digital storytelling process and its applications to public health research and practice. Next, we explore 6 common challenges: fuzzy boundaries, recruitment and consent to participate, power of shaping, representation and harm, confidentiality, and release of materials. We discuss their complexities and offer some considerations for ethical practice. We hope this article serves as a catalyst for expanded dialogue about the need for high standards of integrity and a situated practice of ethics wherein researchers and practitioners reflexively consider ethical decision-making as part of the ongoing work of public health.

    Bahill, A Terry; Baldwin, David G

    2007-07-01

    The right-hand rules show the direction of the spin-induced deflection of baseball pitches: thus, they explain the movement of the fastball, curveball, slider and screwball. The direction of deflection is described by a pair of right-hand rules commonly used in science and engineering. Our new model for the magnitude of the lateral spin-induced deflection of the ball considers the orientation of the axis of rotation of the ball relative to the direction in which the ball is moving. This paper also describes how models based on somatic metaphors might provide variability in a pitcher's repertoire.

    2015-01-01

    The mathematical modelling of the behaviour of microbial growth is widely desired in order to control, predict and design food and bioproduct processing, stability and safety. This work develops and proposes a new semi-empirical mathematical model, based on an autocatalytic kinetic, to describe the microbial growth through its biomass concentration. The proposed model was successfully validated using 15 microbial growth patterns, covering the three most important types of microorganisms in food and biotechnological processing (bacteria, yeasts and moulds). Its main advantages and limitations are discussed, as well as the interpretation of its parameters. It is shown that the new model can be used to describe the behaviour of microbial growth.

  1. A Quark Transport Theory to describe Nucleon--Nucleon Collisions

    CERN Document Server

    Kalmbach, U; Biro, T S; Mosel, U

    1993-01-01

    On the basis of the Friedberg-Lee model we formulate a semiclassical transport theory to describe the phase-space evolution of nucleon-nucleon collisions on the quark level. The time evolution is given by a Vlasov-equation for the quark phase-space distribution and a Klein-Gordon equation for the mean-field describing the nucleon as a soliton bag. The Vlasov equation is solved numerically using an extended testparticle method. We test the confinement mechanism and mean-field effects in 1+1 dimensional simulations.

    Thoroughly characterizing and continuously monitoring the public health workforce is necessary for ensuring capacity to deliver public health services. A prerequisite for this is to develop a standardized methodology for classifying public health workers, permitting valid comparisons across agencies and over time, which does not exist for the public health workforce. An expert working group, all of whom are authors on this paper, was convened during 2012-2014 to develop a public health workforce taxonomy. The purpose of the taxonomy is to facilitate the systematic characterization of all public health workers while delineating a set of minimum data elements to be used in workforce surveys. The taxonomy will improve the comparability across surveys, assist with estimating duplicate counting of workers, provide a framework for describing the size and composition of the workforce, and address other challenges to workforce enumeration. The taxonomy consists of 12 axes, with each axis describing a key characteristic of public health workers. Within each axis are multiple categories, and sometimes subcategories, that further define that worker characteristic. The workforce taxonomy axes are occupation, workplace setting, employer, education, licensure, certification, job tasks, program area, public health specialization area, funding source, condition of employment, and demographics. The taxonomy is not intended to serve as a replacement for occupational classifications but rather is a tool for systematically categorizing worker characteristics. The taxonomy will continue to evolve as organizations implement it and recommend ways to improve this tool for more accurate workforce data collection.

    Student engagement in classroom activities is usually described as a function of factors such as human needs, affect, intention, motivation, interests, identity, and others. We take a different approach and develop a framework that models classroom engagement as a function of students' "conceptual competence" in the "specific content" (e.g., the…

  4. A visual metaphor describing neural dynamics in schizophrenia.

    Directory of Open Access Journals (Sweden)

    Nico J M van Beveren

    Full Text Available BACKGROUND: In many scientific disciplines the use of a metaphor as an heuristic aid is not uncommon. A well known example in somatic medicine is the 'defense army metaphor' used to characterize the immune system. In fact, probably a large part of the everyday work of doctors consists of 'translating' scientific and clinical information (i.e. causes of disease, percentage of success versus risk of side-effects into information tailored to the needs and capacities of the individual patient. The ability to do so in an effective way is at least partly what makes a clinician a good communicator. Schizophrenia is a severe psychiatric disorder which affects approximately 1% of the population. Over the last two decades a large amount of molecular-biological, imaging and genetic data have been accumulated regarding the biological underpinnings of schizophrenia. However, it remains difficult to understand how the characteristic symptoms of schizophrenia such as hallucinations and delusions are related to disturbances on the molecular-biological level. In general, psychiatry seems to lack a conceptual framework with sufficient explanatory power to link the mental- and molecular-biological domains. METHODOLOGY/PRINCIPAL FINDINGS: Here, we present an essay-like study in which we propose to use visualized concepts stemming from the theory on dynamical complex systems as a 'visual metaphor' to bridge the mental- and molecular-biological domains in schizophrenia. We first describe a computer model of neural information processing; we show how the information processing in this model can be visualized, using concepts from the theory on complex systems. We then describe two computer models which have been used to investigate the primary theory on schizophrenia, the neurodevelopmental model, and show how disturbed information processing in these two computer models can be presented in terms of the visual metaphor previously described. Finally, we describe the

  5. Collective Philanthropy: Describing and Modeling the Ecology of Giving

    Gottesman, William L; Dodds, Peter Sheridan

    2013-01-01

    Reflective of income and wealth distributions, philanthropic gifting appears to follow an approximate power-law size distribution as measured by the size of gifts received by individual institutions. We explore the ecology of gifting by analysing data sets of individual gifts for a diverse group of institutions dedicated to education, medicine, art, public support, and religion. We find that the detailed forms of gift-size distributions differ across but are relatively constant within charity categories. We construct a model for how a donor's income affects their giving preferences in different charity categories, offering a mechanistic explanation for variations in institutional gift-size distributions. We discuss how knowledge of gift-sized distributions may be used to assess an institution's gift-giving profile, to help set fundraising goals, and to design an institution-specific giving pyramid.

  6. New models for describing outliers in meta-analysis.

    Science.gov (United States)

    Baker, Rose; Jackson, Dan

    2016-09-01

    An unobserved random effect is often used to describe the between-study variation that is apparent in meta-analysis datasets. A normally distributed random effect is conventionally used for this purpose. When outliers or other unusual estimates are included in the analysis, the use of alternative random effect distributions has previously been proposed. Instead of adopting the usual hierarchical approach to modelling between-study variation, and so directly modelling the study specific true underling effects, we propose two new marginal distributions for modelling heterogeneous datasets. These two distributions are suggested because numerical integration is not needed to evaluate the likelihood. This makes the computation required when fitting our models much more robust. The properties of the new distributions are described, and the methodology is exemplified by fitting models to four datasets. © 2015 The Authors.

  7. Galactic Rotation Described with Bulge+Disk Gravitational Models

    CERN Document Server

    Gallo, C F

    2008-01-01

    Observations reveal that mature spiral galaxies consist of stars, gases and plasma approximately distributed in a thin disk of circular shape, usually with a central bulge. The rotation velocities quickly increase from the galactic center and then achieve a constant velocity from the core to the periphery. The basic dynamic behavior of a mature spiral galaxy, such as the Milky Way, is well described by simple models balancing Newtonian gravitational forces against the centrifugal forces associated with a rotating thin axisymmetric disk. In this research, we investigate the effects of adding central bulges to thin disk gravitational models. Even with the addition of substantial central bulges, all the critical essential features of our thin disk gravitational models are preserved. (1) Balancing Newtonian gravitational and centrifugal forces at every point within the disk yields computed radial mass distributions that describe the measured rotation velocity profiles of mature spiral galaxies successfully.

    Oculoectodermal syndrome is a rare disease characterized by the association of aplasia cutis congenita, epibulbar dermoids, and other abnormalities. This report describes the twentieth case of the disease. We report a 4-year-old female child who presented with the classical features of the syndrome: aplasia cutis congenita and epibulbar dermoids. Our case expands the clinical spectrum of the disease to include: diffuse hyperpigmentation (some following the Blaschko´s lines); hypopigmented skin areas on the trunk; arachnoid cyst on the right fronto-parietal border; rounded left side of the hippocampus; and dermoid cyst underlying the bulb-medullary transition. Our patient also reported infantile hemangioma on the right wrist and verrucous hemangioma on the left leg, the latter not previously described in the literature.

  9. A six-parameter space to describe galaxy diversification

    CERN Document Server

    Fraix-Burnet, Didier; Chattopadhyay, Asis Kumar; Davoust, Emmanuel; Thuillard, Marc

    2012-01-01

    Galaxy diversification proceeds by transforming events like accretion, interaction or mergers. These explain the formation and evolution of galaxies that can now be described with many observables. Multivariate analyses are the obvious tools to tackle the datasets and understand the differences between different kinds of objects. However, depending on the method used, redundancies, incompatibilities or subjective choices of the parameters can void the usefulness of such analyses. The behaviour of the available parameters should be analysed before an objective reduction of dimensionality and subsequent clustering analyses can be undertaken, especially in an evolutionary context. We study a sample of 424 early-type galaxies described by 25 parameters, ten of which are Lick indices, to identify the most structuring parameters and determine an evolutionary classification of these objects. Four independent statistical methods are used to investigate the discriminant properties of the observables and the partitioni...

  10. Statistical models describing the energy signature of buildings

    DEFF Research Database (Denmark)

    Bacher, Peder; Madsen, Henrik; Thavlov, Anders

    2010-01-01

    Approximately one third of the primary energy production in Denmark is used for heating in buildings. Therefore efforts to accurately describe and improve energy performance of the building mass are very important. For this purpose statistical models describing the energy signature of a building, i.......e. the heat dynamics of the building, have been developed. The models can be used to obtain rather detailed knowledge of the energy performance of the building and to optimize the control of the energy consumption for heating, which will be vital in conditions with increasing fluctuation of the energy supply...... or varying energy prices. The paper will give an overview of statistical methods and applied models based on experiments carried out in FlexHouse, which is an experimental building in SYSLAB, Risø DTU. The models are of different complexity and can provide estimates of physical quantities such as UA...

  11. Double sigmoidal models describing the growth of coffee berries

    Directory of Open Access Journals (Sweden)

    Tales Jesus Fernandes

    Full Text Available ABSTRACT: This study aimed to verify if the growth pattern of coffee berries, considering fresh mass accumulation over time, is double sigmoid and to select the most suitable nonlinear model to describe such behavior. Data used consisted of fourteen longitudinal observations of average fresh mass of coffee berries obtained in an experiment with the cultivar Obatã IAC 1669-20. The fits provided by the Logistic and Gompertz models were compared in their single and double versions. Parameters were estimated using the least squares method using the Gauss-Newton algorithm implemented in the nls function of the R software. It can be concluded that the growth pattern of the coffee fruit, in fresh mass accumulation, is double sigmoid. The double Gompertz and double Logistic models were adequate to describe such a growth curve, with a superiority of the double Logistic model.

  12. Which number system is "best" for describing empirical reality?

    CERN Document Server

    Visser, Matt

    2013-01-01

    Eugene Wigner's much discussed notion of the "unreasonable effectiveness of mathematics" in describing the physics of empirical reality is simultaneously both trivial and profound. After all, the relevant mathematics was, (in the first instance), originally developed in order to be useful in describing empirical reality. On the other hand, certain aspects of the mathematical superstructure have now taken on a life of their own, with at least some features of the mathematical superstructure greatly exceeding anything that can be directly probed or verified, or even justified, by empirical experiment. Specifically, I wish to raise the possibility that the real number system, (with its nevertheless pragmatically very useful tools of real analysis, and mathematically rigorous notions of differentiation and integration), may nevertheless constitute a "wrong turn" when it comes to modelling empirical reality. Without making any definitive recommendation, I shall discuss several alternatives.

  13. Curie law for systems described by kappa distributions

    Science.gov (United States)

    Livadiotis, George

    2016-01-01

    We derive the magnetization of a system, Pierre Curie's law, for paramagnetic particles out of thermal equilibrium described by kappa distributions. The analysis uses the theory and formulation of the kappa distributions that describe particle systems with a non-zero potential energy. Among other results, emphasis is placed on the effect of kappa distribution on the phenomenon of having strong magnetization at high temperatures. At thermal equilibrium, high temperature leads to weak magnetization. Out of thermal equilibrium, however, strong magnetization at high temperatures is rather possible, if the paramagnetic particle systems reside far from thermal equilibrium, i.e., at small values of kappa. The application of the theory to the space plasma at the outer boundaries of our heliosphere, the inner heliosheath, leads to an estimation of the ion magnetic moment for this space plasma, that is, μ ≈ 138+/-7 \\text{eV/nT} .

    Ganio, L.M.; Torgersen, C.E.; Gresswell, R.E.

    2005-01-01

    The shape and configuration of branched networks influence ecological patterns and processes. Recent investigations of network influences in riverine ecology stress the need to quantify spatial structure not only in a two-dimensional plane, but also in networks. An initial step in understanding data from stream networks is discerning non-random patterns along the network. On the other hand, data collected in the network may be spatially autocorrelated and thus not suitable for traditional statistical analyses. Here we provide a method that uses commercially available software to construct an empirical variogram to describe spatial pattern in the relative abundance of coastal cutthroat trout in headwater stream networks. We describe the mathematical and practical considerations involved in calculating a variogram using a non-Euclidean distance metric to incorporate the network pathway structure in the analysis of spatial variability, and use a non-parametric technique to ascertain if the pattern in the empirical variogram is non-random.

    Statoliths of cephalopods are small, hard calcareous stones which lie within the cartilaginous skulls of octopods, sepioids and teuthoids1. Fossil statoliths, clearly belonging to genera which are alive today, have previously been described from 11 Cenozoic deposits spanning from the Eocene to the Pleistocene in North America2–5. Such statoliths are of particular interest because they provide a means of studying the evolution of living cephalopod groups which have no calcareous shells, includ...

    Tashiro, Tohru; Minagawa, Hiroe; Chiba, Michiko

    2013-02-01

    We propose a hierarchical logistic equation as a model to describe the dynamical behaviour of a penetration rate of a prevalent stuff. In this model, a memory, how many people who already possess it a person who does not process it yet met, is considered, which does not exist in the logistic model. As an application, we apply this model to iPod sales data, and find that this model can approximate the data much better than the logistic equation.

    The systematic use of ambient scents is a trend in service companies that is accompanied by increasing research attention. However, we lack a theoretical framework that ad-dresses ambient scents' specific role in physical surroundings of services.

  19. On the problems of describing joint axis alignment.

    Science.gov (United States)

    Ball, Kevin A; Greiner, Thomas M

    2008-01-01

    Each three-dimensional joint possesses at least one potentially oblique axis of rotation. Several systems are used to express joint axis alignment. One system, designated the plane projection (PP) method, describes angles based on orthogonal projections onto two, of the three, anatomical planes. Alternatively, a joint axis may be described in two different ways using two sequential Cardan angle rotations. These expression systems all lay claim to similar descriptive labels, such as deviation and elevation. Difficulties arise as researchers use these various methods to compare their own data to the results of others. A joint axis alignment, described as 27 degrees deviation and 41 degrees elevation in PP, differs by as much as 6 degrees when expressed as Cardan angles. Differences among expression systems increase as the joint axis alignment becomes more oblique -- eventually differing by as much as 75 degrees . This paper explores implications for this lack of congruence among the joint axis expression systems. Effective steps in dealing with these issues begin with recognizing the existence and extent of the problem. The paper provides a common set of algorithms to illustrate and alleviate the possible problems associated with the exchange of joint axis alignment data.

  20. On Differential Equations Describing 3-Dimensional Hyperbolic Spaces

    Institute of Scientific and Technical Information of China (English)

    WU Jun-Yi; DING Qing; Keti Tenenblat

    2006-01-01

    In this paper, we introduce the notion of a (2+1)-dimensional differential equation describing threedimensional hyperbolic spaces (3-h.s.). The (2+1)-dimensional coupled nonlinear Schrodinger equation and its sister equation, the (2+1)-dimensional coupled derivative nonlinear Schrodinger equation, are shown to describe 3-h.s. The (2+1)-dimensional generalized HF model: St = (1/2i [S, Sy] + 2iσS)x, σx = 1-4itr(SSxSy), in which S ∈ GLC(2)/GLC(1)×GLC(1),provides another example of (2+1)-dimensional differential equations describing 3-h.s. As a direct consequence, the geometric construction of an infinite number of conservation laws of such equations is illustrated. Furthermore we display a new infinite number of conservation laws of the (2+1)-dimensional nonlinear Schrodinger equation and the (2+1)odimensional derivative nonlinear Schrodinger equation by a geometric way.

  1. HERMES: A Model to Describe Deformation, Burning, Explosion, and Detonation

    Energy Technology Data Exchange (ETDEWEB)

    Reaugh, J E

    2011-11-22

    HERMES (High Explosive Response to MEchanical Stimulus) was developed to fill the need for a model to describe an explosive response of the type described as BVR (Burn to Violent Response) or HEVR (High Explosive Violent Response). Characteristically this response leaves a substantial amount of explosive unconsumed, the time to reaction is long, and the peak pressure developed is low. In contrast, detonations characteristically consume all explosive present, the time to reaction is short, and peak pressures are high. However, most of the previous models to describe explosive response were models for detonation. The earliest models to describe the response of explosives to mechanical stimulus in computer simulations were applied to intentional detonation (performance) of nearly ideal explosives. In this case, an ideal explosive is one with a vanishingly small reaction zone. A detonation is supersonic with respect to the undetonated explosive (reactant). The reactant cannot respond to the pressure of the detonation before the detonation front arrives, so the precise compressibility of the reactant does not matter. Further, the mesh sizes that were practical for the computer resources then available were large with respect to the reaction zone. As a result, methods then used to model detonations, known as {beta}-burn or program burn, were not intended to resolve the structure of the reaction zone. Instead, these methods spread the detonation front over a few finite-difference zones, in the same spirit that artificial viscosity is used to spread the shock front in inert materials over a few finite-difference zones. These methods are still widely used when the structure of the reaction zone and the build-up to detonation are unimportant. Later detonation models resolved the reaction zone. These models were applied both to performance, particularly as it is affected by the size of the charge, and to situations in which the stimulus was less than that needed for reliable

  5. A proposal to describe a phenomenon of expanding language

    Science.gov (United States)

    Swietorzecka, Kordula

    Changes of knowledge, convictions or beliefs are subjects of interest in frame of so called epistemic logic. There are various proposed descriptions of a process (or its results) in which so a called agent may invent certain changes in a set of sentences that he had already chosen as a point of his knowledge, convictions or beliefs (and this is also considered in case of many agents). In the presented paper we are interested in the changeability of an agent's language which is by its own independent from already mentioned changes. Modern epistemic formalizations assume that the agent uses a fixed (and so we could say: static) language in which he expresses his various opinions which may change. Our interest is to simulate a situation when a language is extended by adding to it new expressions which were not known by the agent so he couldn't even consider them as subjects of his opinions. Actually such a phenomenon happens both in natural and scientific languages. Let us mention a fact of expanding languages in process of learning or in result of getting of new data about some described domain. We propose a simple idealization of extending sentential language used by one agent. Actually the language is treated as a family of so called n-languages which get some epistemic interpretation. Proposed semantics enables us to distinguish between two different types of changes - these which occur because of changing agent's convictions about logical values of some n-sentences - we describe them using one place operator C to be read it changes that - and changes that consist in increasing the level of n-language by adding to it new expressions. However the second type of change - symbolized by variable G - may be also considered independently of the first one. The logical frame of our considerations comes from and it was originally used to describe Aristotelian theory of substantial changes. This time we apply the mentioned logic in epistemology.

  6. Two heuristic approaches to describe periodicities in genomic microarrays

    Directory of Open Access Journals (Sweden)

    Jörg Aßmus

    2009-09-01

    Full Text Available In the first part we discuss the filtering of panels of time series based on singular value decomposition. The discussion is based on an approach where this filtering is used to normalize microarray data. We point out effects on the periodicity and phases for time series panels. In the second part we investigate time dependent periodic panels with different phases. We align the time series in the panel and discuss the periodogram of the aligned time series with the purpose of describing the periodic structure of the panel. The method is quite powerful assuming known phases in the model, but it deteriorates rapidly for noisy data.

    2010-01-01

    In this paper we study a model describing the growth of necrotic tumors in different regimes of vascularisation. The tumor consists of a necrotic core of death cells and a surrounding nonnecrotic shell. The corresponding mathematical formulation is a moving boundary problem where both boundaries delimiting the nonnecrotic shell are allowed to evolve in time.We determine all radially symmetric stationary solutions of the problem and reduce the moving boundary problem into a nonlinear evolution. Parabolic theory provides us the perfect context in order to show local well-posed of the problem for small initial data.

    An extension of the nonlinear feedback (NLF) formalism to describe regimes of hyper- and high-inflation in economy is proposed in the present work. In the NLF model the consumer price index (CPI) exhibits a finite time singularity of the type $1/(t_c -t)^{(1- \\beta)/\\beta}$, with $\\beta>0$, predicting a blow up of the economy at a critical time $t_c$. However, this model fails in determining $t_c$ in the case of weak hyperinflation regimes like, e.g., that occurred in Israel. To overcome this...

    We discuss results recently given in an article by M. Tegmark (quant-ph/9907009) where he argues that neurons can be described appropriately by pure classical physics. This letter is dedicated to the question if this is really the case when the role of dissipation and noise -- the two concurrent phenomena present in these biological structures -- is taken into account. We argue that dissipation and noise might well be of quantum origin and give also a possible reason why neural dynamics is not classical.

    Despite increasing popularity, health consequences of vaping (smoking electronic cigarettes, e-cigarettes) are poorly described. Few studies suggest that vaping has less deleterious effects on lung function than smoking conventional cigarettes. One large study found that e-cigarettes were as efficient as nicotine patches in smoking cessation. The long-term consequences of vaping are however unknown and while some experts are open towards e-cigarettes as a safer way of satisfying nicotine addiction, others worry that vaping in addition to presenting a health hazard may lead to an increased number of smokers of conventional cigarettes.

In accordance with the black holes uniqueness theorems, the presence of the quadrupole completely changes the geometric properties of the corresponding spacetime that turns out to contain naked singularities for all possible values of the quadrupole parameter. The naked singularities, however, can be covered by interior solutions that correspond to perfect fluid sources with no specific equations of state. We conclude that the $q-$metric can be used to describe the entire spacetime generated by static deformed compact objects.

    The two-dimensional Dirac operator describes low-energy excitations in graphene. Different choices for the boundary conditions give rise to qualitative differences in the spectrum of the resulting operator. For a family of boundary conditions, we find a lower bound to the spectral gap around zero, proportional to |Ω|-1/2, where {Ω } \\subset R2 is the bounded region where the Dirac operator acts. This family contains the so-called infinite mass and armchair cases used in the physics literature for the description of graphene quantum dots.

  13. Failure of random matrix theory to correctly describe quantum dynamics.

    Kottos, T; Cohen, D

    2001-12-01

    Consider a classically chaotic system that is described by a Hamiltonian H(0). At t=0 the Hamiltonian undergoes a sudden change (H)0-->H. We consider the quantum-mechanical spreading of the evolving energy distribution, and argue that it cannot be analyzed using a conventional random-matrix theory (RMT) approach. Conventional RMT can be trusted only to the extent that it gives trivial results that are implied by first-order perturbation theory. Nonperturbative effects are sensitive to the underlying classical dynamics, and therefore the Planck's over 2 pi-->0 behavior for effective RMT models is strikingly different from the correct semiclassical limit.

  14. Can CA describe collective effects of polluting agents?

    Troisi, A.

    2015-03-01

    Pollution represents one of the most relevant issues of our time. Several studies are on stage but, generally, they do not consider competitive effects, paying attention only to specific agents and their impact. In this paper, it is suggested a different scheme. At first, it is proposed a formal model of competitive noxious effects. Second, by generalizing a previous algorithm capable of describing urban growth, it is developed a cellular automata (CA) model that provides the effective impact of a variety of pollutants. The final achievement is a simulation tool that can model pollution combined effects and their dynamical evolution in relation to anthropized environments.

    Jing-min He; Rong Wu; Hua-yue Zhang

    2008-01-01

    In this paper we mainly study the ruin probability of a surplus process described by a piecewise deterministic Markov process (PDMP). An integro-differentiai equation for the ruin probability is derived. Under a certain assumption, it can be transformed into the ruin probability of a risk process whose premiums depend on the current reserves. Using the same argument as that in Asmussen and Nielsen[2], the ruin probability and its upper bounds are obtained. Finally, we give an analytic expression for ruin probability and its upper bounds when the claim-size is exponentially distributed.

    2006-01-01

    Web servers at the National Library of Medicine (NLM) displayed images of ten skin lesions to practicing dermatologists and provided an online form for capturing text they used to describe the pictures. The terms were submitted to the UMLS Metathesaurus (Meta). Concepts retrieved, their semantic types, definitions and synonyms, were returned to each subject in a second web-based form. Subjects rated the concepts against their own descriptive terms. They submitted 825 terms, 346 of which were unique and 300 mapped to UMLS concepts. The dermatologists rated 295 concepts as 'Exact Match' and they accomplished both tasks in about 30 min.

    2014-01-01

    Little is available in scholarly literature about how HIV-positive prisoners, especially in low-income countries, access antiretroviral therapy (ART) medication. We interviewed 18 prisoners at a large prison in Namibia to identify barriers to medication adherence. The lead nurse researcher was a long-standing clinic employee at the prison, which afforded her access to the population. We identified six significant barriers to adherence, including (1) the desire for privacy and anonymity in a setting where HIV is strongly stigmatized; (2) the lack of simple supports for adherence, such as availability of clocks; (3) insufficient access to food to support the toll on the body of ingesting taxing ART medications; (4) commodification of ART medication; (5) the brutality and despair in the prison setting, generally leading to discouragement and a lack of motivation to strive for optimum health; and (6) the lack of understanding about HIV, how it is transmitted, and how it is best managed. Because most prisoners eventually transition back to communitysettings when their sentences are served, investments in prison health represent important investments in public health.

  20. In their own words: describing Canadian physician leadership.

    Science.gov (United States)

    Snell, Anita J; Dickson, Graham; Wirtzfeld, Debrah; Van Aerde, John

    2016-07-04

    Purpose This is the first study to compile statistical data to describe the functions and responsibilities of physicians in formal and informal leadership roles in the Canadian health system. This mixed-methods research study offers baseline data relative to this purpose, and also describes physician leaders' views on fundamental aspects of their leadership responsibility. Design/methodology/approach A survey with both quantitative and qualitative fields yielded 689 valid responses from physician leaders. Data from the survey were utilized in the development of a semi-structured interview guide; 15 physician leaders were interviewed. Findings A profile of Canadian physician leadership has been compiled, including demographics; an outline of roles, responsibilities, time commitments and related compensation; and personal factors that support, engage and deter physicians when considering taking on leadership roles. The role of health-care organizations in encouraging and supporting physician leadership is explicated. Practical implications The baseline data on Canadian physician leaders create the opportunity to determine potential steps for improving the state of physician leadership in Canada; and health-care organizations are provided with a wealth of information on how to encourage and support physician leaders. Using the data as a benchmark, comparisons can also be made with physician leadership as practiced in other nations. Originality/value There are no other research studies available that provide the depth and breadth of detail on Canadian physician leadership, and the embedded recommendations to health-care organizations are informed by this in-depth knowledge.

  1. Extended nonlinear feedback model for describing episodes of high inflation

    Science.gov (United States)

    Szybisz, Martín A.; Szybisz, Leszek

    2017-01-01

    An extension of the nonlinear feedback (NLF) formalism to describe regimes of hyper- and high-inflation in economy is proposed in the present work. In the NLF model the consumer price index (CPI) exhibits a finite time singularity of the type 1 /(tc - t) (1 - β) / β, with β > 0, predicting a blow up of the economy at a critical time tc. However, this model fails in determining tc in the case of weak hyperinflation regimes like, e.g., that occurred in Israel. To overcome this trouble, the NLF model is extended by introducing a parameter γ, which multiplies all terms with past growth rate index (GRI). In this novel approach the solution for CPI is also analytic being proportional to the Gaussian hypergeometric function 2F1(1 / β , 1 / β , 1 + 1 / β ; z) , where z is a function of β, γ, and tc. For z → 1 this hypergeometric function diverges leading to a finite time singularity, from which a value of tc can be determined. This singularity is also present in GRI. It is shown that the interplay between parameters β and γ may produce phenomena of multiple equilibria. An analysis of the severe hyperinflation occurred in Hungary proves that the novel model is robust. When this model is used for examining data of Israel a reasonable tc is got. High-inflation regimes in Mexico and Iceland, which exhibit weaker inflations than that of Israel, are also successfully described.

  2. Asphere, O asphere, how shall we describe thee?

    Two key criteria govern the characterization of nominal shapes for aspheric optical surfaces. An efficient representation describes the spectrum of relevant shapes to the required accuracy by using the fewest decimal digits in the associated coefficients. Also, a representation is more effective if it can, in some way, facilitate other processes - such as optical design, tolerancing, or direct human interpretation. With the development of better tools for their design, metrology, and fabrication, aspheric optics are becoming ever more pervasive. As part of this trend, aspheric departures of up to a thousand microns or more must be characterized at almost nanometre precision. For all but the simplest of shapes, this is not as easy as it might sound. Efficiency is therefore increasingly important. Further, metrology tools continue to be one of the weaker links in the cost-effective production of aspheric optics. Interferometry particularly struggles to deal with steep slopes in aspheric departure. Such observations motivated the ideas described in what follows for modifying the conventional description of rotationally symmetric aspheres to use orthogonal bases that boost efficiency. The new representations can facilitate surface tolerancing as well as the design of aspheres with cost-effective metrology options. These ideas enable the description of aspheric shapes in terms of decompositions that not only deliver improved efficiency and effectiveness, but that are also shown to admit direct interpretations. While it's neither poetry nor a cure-all, an old blight can be relieved.

    The accurate measurement of geographic patterns of health care utilization is a prerequisite for the study of geographic variations in health care utilization. While several measures have been developed to measure how accurately geographic units reflect the health care utilization patterns of residents, they have been only applied to hospitalization and need further evaluation. This study aimed to evaluate geographic indices describing health care utilization. We measured the utilization rate and four health care utilization indices (localization index, outflow index, inflow index, and net patient flow) for eight major procedures (coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, surgery after hip fracture, knee replacement surgery, caesarean sections, hysterectomy, computed tomography scans, and magnetic resonance imaging scans) according to three levels of geographic units in Korea. Data were obtained from the National Health Insurance database in Korea. We evaluated the associations among the health care utilization indices and the utilization rates. In higher-level geographic units, the localization index tended to be high, while the inflow index and outflow index were lower. The indices showed different patterns depending on the procedure. A strong negative correlation between the localization index and the outflow index was observed for all procedures. Net patient flow showed a moderate positive correlation with the localization index and the inflow index. Health care utilization indices can be used as a proxy to describe the utilization pattern of a procedure in a geographic unit.

    This study looks to describe the workplace culture from the viewpoints of stress, job satisfaction and practice environment. Data were collected from nurses (n = 109) using a web-based survey, The Person-Centred Nursing Index, from two purposefully selected hospital districts in Finland. Data were statistically analysed. Nurses described their workplace culture in slightly positive terms. Nurses only occasionally experienced stress (mean = 2.56, SD = 0.55) and were fairly satisfied with their job (mean = 4.75, SD = 0.66) and their practice environment (mean = 4.42, SD = 0.81). Demographic variables such as the nurses' age, length of time in nursing, time at their present hospital, working shifts and their use of patient restriction were more frequently associated with their perceived workplace culture. Older nurses and those with a longer work history in the nursing profession tended to be more satisfied with their workplace culture in psychiatric nursing. Young and/or newly graduated nurses felt more negatively on their workplace culture; this issue should be recognised and addressed with appropriate support and mentoring. Nurses who used restrictive measures were more often less satisfied with their workplace culture. Continuous efforts are needed to reduce the use of coercive measures, which challenge also the managers to support nursing practice to be more person-centred. © 2017 Nordic College of Caring Science.

  5. First order reversal curves diagrams for describing ferroelectric switching characteristics

    Directory of Open Access Journals (Sweden)

    Liliana Mitoseriu

    2009-06-01

    Full Text Available First Order Reversal Curves (FORC are polarization-field dependences described between saturation field Esat and a variable reversal field Er∈(-Esat, Esat. The FORC diagrams were proposed to describe some characteristics of the switching process in ferroelectrics. The approach is related to the Preisach model which considers the distribution of the elementary switchable units over their coercive and bias fields. The influence of the anisotropic porosity in Pb(Zr,TiO3 bulk ceramics on the FORC distributions demonstrated the existence of a positive/negative bias as a result of the confinement induced by anisotropy. The reducing of grain size in Ba(Zr,TiO3 ceramics causes an increase of the ratio of the reversible/irreversible components of the polarization on the FORC distribution indicating the tendency of system towards the superparaelectric state. The FORC method demonstrates to provide a kind of ‘fingerprinting’ of various types of switching characteristics in ferroic systems.

  6. Conjugated Molecules Described by a One-Dimensional Dirac Equation.

    2010-06-08

    Starting from the Hückel Hamiltonian of conjugated hydrocarbon chains (ethylene, allyl radical, butadiene, pentadienyl radical, hexatriene, etc.), we perform a simple unitary transformation and obtain a Dirac matrix Hamiltonian. Thus already small molecules are described exactly in terms of a discrete Dirac equation, the continuum limit of which yields a one-dimensional Dirac Hamiltonian. Augmenting this Hamiltonian with specially adapted boundary conditions, we find that all the orbitals of the unsaturated hydrocarbon chains are reproduced by the continuous Dirac equation. However, only orbital energies close to the highest occupied molecular orbital/lowest unoccupied molecular orbital energy are accurately predicted by the Dirac equation. Since it is known that a continuous Dirac equation describes the electronic structure of graphene around the Fermi energy, our findings answer the question to what extent this peculiar electronic structure is already developed in small molecules containing a delocalized π-electron system. We illustrate how the electronic structure of small polyenes carries over to a certain class of rectangular graphene sheets and eventually to graphene itself. Thus the peculiar electronic structure of graphene extends to a large degree to the smallest unsaturated molecule (ethylene).

  7. Motion in a stochastic layer described by symbolic dynamics

    1997-07-01

    The motion in the stochastic layer surrounding an island can be studied by using the standard map: this problem is of direct relevance to the diffusion of magnetic field lines in a tokamak. In a previous work it was shown that this process can be adequately modelled by a continuous time random walk (CTRW) describing transitions of the running point between three basins representing, respectively, trapped motion around the island, and passing motion above or below the island. The sticking property of the island deeply modifies the nature of the transport process, leading to sub-diffusive behavior. In the present work it is shown that the motion can be analyzed in terms of a symbolic dynamics which leads to the possibility of an automatic measurement of the data necessary for the construction of the CTRW. The logical features of the procedure are described, and the method is applied to an analysis of long time series, thus completing the results of the previous work. (author) 10 refs.

  8. A more robust Boolean model describing inhibitor binding

    Institute of Scientific and Technical Information of China (English)

    Zhaoqian Steven XIE; Chao TANG

    2008-01-01

    From the first application of the Boolean model to the cell cycle regulation network of budding yeast, new regulative pathways have been discovered, par-ticularly in the G1/S transition circuit. This discovery called for finer modeling to study the essential biology, and the resulting outcomes are first introduced in the ar-ticle. A traditional Boolean network model set up for the new G1/S transition circuit shows that it cannot correctly simulate real biology unless the model parameters are fine tuned. The deficiency is caused by an overly coarse-grained description of the inhibitor binding process, which shall be overcome by a two-vector model proposed whose robustness is surveyed using random perturba-tions. Simulations show that the proposed two-vector model is much more robust in describing inhibitor binding processes within the Boolean framework.

  9. Does classical mechanics always adequately describe "classical physical reality"

    CERN Document Server

    Shemi-zadeh, V E

    2002-01-01

    The article is dedicated to discussion of irreversibility and foundation of statistical mechanics "from the first principles". Taking into account infinitesimal and, as it seems, neglectful for classical mechanics fluctuations of the physical vacuum, makes a deterministic motion of unstable dynamic systems is broken ("spontaneous determinism breaking", "spontaneous stochastization"). Vacuum fluctuations play part of the trigger, starting the powerful mechanism of exponent instability. The motion of the dynamic systems becomes irreversible and stochastic. Classical mechanics turns out to be applicable only for a small class of stable dynamic systems with zero Kolmogorov-Sinay entropy $h=0$. For alternative "Stochastic mechanics" there are corresponding equations of motion and Master Equation, describing irreversible evolution of the initial distribution function to equilibrium state.

    2007-01-01

    In the functional properties of complex networks, modules play a central role.In this paper,we propose a new method to detect and describe the modular structures of weighted networks. In order to test the proposed method, as an example, we use our method to analyse the structural properties of the Chinese railway network. Here, the stations are regarded as the nodes and the track sections are regarded as the links. Rigorous analysis of the existing data shows that using the proposed algorithm, the nodes of network can be classified naturally. Moreover, there are several core nodes in each module. Remarkably, we introduce the correlation function Grs, and use it to distinguish the different modules in weighted networks.

    2015-01-01

    The paper aims to adopt the complex octonion to formulate the angular momentum, torque, and force etc in the electromagnetic and gravitational fields. Applying the octonionic representation enables one single definition of angular momentum (or torque, force) to combine some physics contents, which were considered to be independent of each other in the past. J. C. Maxwell used simultaneously two methods, the vector terminology and quaternion analysis, to depict the electromagnetic theory. It motivates the paper to introduce the quaternion space into the field theory, describing the physical feature of electromagnetic and gravitational fields. The spaces of two fields can be chosen as the quaternion spaces, while the coordinate component of quaternion space is able to be the complex number. The quaternion space of electromagnetic field is independent of that of gravitational field. These two quaternion spaces may compose one octonion space. Contrarily, one octonion space can be separated into two subspaces, the...

  12. Describing linguistic information in a behavioural framework: Possible or not?

    Energy Technology Data Exchange (ETDEWEB)

    De Cooman, G. [Universiteit Gent, Zwijnaarde (Belgium)

    1996-12-31

    The paper discusses important aspects of the representation of linguistic information, using imprecise probabilities with a behavioural interpretation. We define linguistic information as the information conveyed by statements in natural language, but restrict ourselves to simple affirmative statements of the type {open_quote}subject-is-predicate{close_quote}. Taking the behavioural stance, as it is described in detail, we investigate whether it is possible to give a mathematical model for this kind of information. In particular, we evaluate Zadeli`s suggestion that we should use possibility measures to this end. We come to tile conclusion that, generally speaking, possibility measures are possibility models for linguistic information, but that more work should be done in order to evaluate the suggestion that they may be the only ones.

    2010-07-01

    In recent years, Cherenkov telescopes like e.g. H.E.S.S. have identified a large number of very-high-energy (VHE) gamma-ray sources as Pulsar wind nebulae (PWNe). The VHE-gamma-ray emission shows a rich diversity of spectral and spatial morphologies. Theoretical models can help to understand and interprete the observed source properties. A simple semi-analytical leptonic model describing VHE gamma-ray emission from PWNe is presented. It assumes diffusion with radiative cooling as the transport mechanism for electrons and their interaction with radiative and interstellar magnetic fields as the origin of electromagnetic radiation. In the framework of this model, spectral and spatial properties of the expected VHE gamma-ray emission from single PWNe may be estimated.

    2016-06-01

    Full Text Available In Sanskrit literature there is a prominent place for Maharshi Valmiki‟s Ramayana. This is one of the very few popular epics which are translated to multiple languages across the world. It has seven kaandas (books, five hundred sargas (chapters and twenty four thousand slokas (verses in it. The vimanas are described in various kaandas of Ramayana. It is said that Ravana had the vimana which could appear and disappear, travel long distances with high speed based on the thought power of the master. A few years ago in the year 2013 researchers from the University of Minnesota have designed a model quadcopter which can be flown by the human thought power. As per Prof Bin He from the University of Minnesota, for the first time humans are able to control the flight of flying robots using just their thought sensed from non-invasive brain waves. German scientists from the Technical University of Munich under the leadership of Professor Tim Fricke have simulated the flight of aircraft using thought power of the pilots. This makes us think if such an aircraft with an advanced technology like this existed once upon a time during the era of Ramayana. Carvings of Ravana‟s vimana in Ellora cave temples help us in comparing it with that of modern Jetpack. Descriptions on seating capacity of Pushpaka vimana help us in comparing the same with Airbus 380-800 which can accommodate 853 passengers. Concepts of invisibility of aircrafts make us think of camouflaging techniques and stealth technology used in modern military aircrafts. All these features help us in analyzing the probable technologies behind vimanas described in Ramayana

  17. Assessing the state of substitution models describing noncoding RNA evolution.

    Allen, James E; Whelan, Simon

    2014-01-01

    Phylogenetic inference is widely used to investigate the relationships between homologous sequences. RNA molecules have played a key role in these studies because they are present throughout life and tend to evolve slowly. Phylogenetic inference has been shown to be dependent on the substitution model used. A wide range of models have been developed to describe RNA evolution, either with 16 states describing all possible canonical base pairs or with 7 states where the 10 mismatched nucleotides are reduced to a single state. Formal model selection has become a standard practice for choosing an inferential model and works well for comparing models of a specific type, such as comparisons within nucleotide models or within amino acid models. Model selection cannot function across different sized state spaces because the likelihoods are conditioned on different data. Here, we introduce statistical state-space projection methods that allow the direct comparison of likelihoods between nucleotide models and 7-state and 16-state RNA models. To demonstrate the general applicability of our new methods, we extract 287 RNA families from genomic alignments and perform model selection. We find that in 281/287 families, RNA models are selected in preference to nucleotide models, with simple 7-state RNA models selected for more conserved families with shorter stems and more complex 16-state RNA models selected for more divergent families with longer stems. Other factors, such as the function of the RNA molecule or the GC-content, have limited impact on model selection. Our models and model selection methods are freely available in the open-source PHASE 3.0 software.

    2010-12-01

    In recent times, various voices in Spain have questioned public health policies as an assault to personal freedom. The present article aims to respond to these voices with ethical and economic arguments. The scope and characteristics of this current of opinion are described. Then, starting with John Stuart Mill, the ethical principles of non-maleficence, beneficence, personal autonomy and justice, as well as related concepts taken from economic efficiency, such as externalities, monopoly, incomplete and asymmetric information, agency relationship, public goods and adverse selection, are discussed. A short mention is made of equity in economics, the welfare state and public health systems. The justification for paternalist actions by the state, as well as limits to these actions, are briefly discussed. Respect for individual freedom does not exclude the implementation of public health actions but rather demands the adoption of such policies. If these actions comply with certain conditions, they do not limit individual freedom but rather serve to protect it. Copyright © 2010 SESPAS. Published by Elsevier Espana. All rights reserved.

    Second order evolution differential equations that describe pseudospherical surfaces are considered. These equations are equivalent to the structure equations of a metric with Gaussian curvature K = - 1, and can be seen as the compatibility condition of an associated sl (2 , R) -valued linear problem, also referred to as a zero curvature representation. Under the assumption that the linear problem is defined by 1-forms ωi =fi1 dx +fi2 dt, i = 1 , 2 , 3, with fij depending on (x , t , z ,z1 ,z2) and such that f21 = η, η ∈ R, we give a complete and explicit classification of equations of the form zt = A (x , t , z) z2 + B (x , t , z ,z1) . According to the classification, these equations are subdivided in three main classes (referred to as Types I-III) together with the corresponding linear problems. Explicit examples of differential equations of each type are determined by choosing certain arbitrary differentiable functions. Svinolupov-Sokolov equations admitting higher weakly nonlinear symmetries, Boltzmann equation and reaction-diffusion equations like Murray equation are some known examples of such equations. Other explicit examples are presented, as well.

    Organizational researchers and practitioners have been interested in organizational change for some time. Historically, they have directed most of their efforts at improving the efficiency of planned top-down change. These efforts were strategic attempts at altering parameters leading to transformational change. Most efforts failed to meet their intended purposes. Transformational organizational change has not been likely. The legitimate systems have been robust. There has been little systematic investigation of the communication occurring during these efforts. The purpose of this essay is to describe results of a mixed methods research project answering two research questions. (a) How do organizational members communicate during a time of turbulence? (b) What features of this communication suggest the potential for or resistance to transformative change? Comparing the results at the beginning of the period to other periods, gives insight into how social actors communicate and enact the organization during a threshold period where transformational change was possible. Results reveal identifiable patterns of communication as communication strategies, parameters, or basins of attraction. The overall pattern explains how micro communication patterns intersect and how the accumulation of these patterns may resist or accomplish change at a macro level.

    Background Ontologies represent powerful tools in information technology because they enhance interoperability and facilitate, among other things, the construction of optimized search engines. To address the need to expand the toolbox available for the control and prevention of vector-borne diseases we embarked on the construction of specific ontologies. We present here IDODEN, an ontology that describes dengue fever, one of the globally most important diseases that are transmitted by mosquitoes. Methodology/Principal Findings We constructed IDODEN using open source software, and modeled it on IDOMAL, the malaria ontology developed previously. IDODEN covers all aspects of dengue fever, such as disease biology, epidemiology and clinical features. Moreover, it covers all facets of dengue entomology. IDODEN, which is freely available, can now be used for the annotation of dengue-related data and, in addition to its use for modeling, it can be utilized for the construction of other dedicated IT tools such as decision support systems. Conclusions/Significance The availability of the dengue ontology will enable databases hosting dengue-associated data and decision-support systems for that disease to perform most efficiently and to link their own data to those stored in other independent repositories, in an architecture- and software-independent manner.

    Motor vehicles are a major source of greenhouse gases, and the rising numbers of motor vehicles and miles driven could lead to more harmful emissions that may ultimately affect the world`s climate. One approach to curtailing such emissions is to use, instead of gasoline, alternative fuels: LPG, compressed natural gas, or alcohol fuels. In addition to the greenhouse gases, pollutants can be harmful to human health: ozone, CO. The Clean Air Act Amendments of 1990 authorized EPA to set National Ambient Air Quality Standards to control this. The Energy Policy Act of 1992 (EPACT) was the first new law to emphasize strengthened energy security and decreased reliance on foreign oil since the oil shortages of the 1970`s. EPACT emphasized increasing the number of alternative-fuel vehicles (AFV`s) by mandating their incremental increase of use by Federal, state, and alternative fuel provider fleets over the new few years. Its goals are far from being met; alternative fuels` share remains trivial, about 0.3%, despite gains. This report describes current and potential markets for AFV`s; it begins by assessing the total vehicle stock, and then it focuses on current use of AFV`s in alternative fuel provider fleets and the potential for use of AFV`s in US households.

  5. Entropic-Skins Geometry to Describe Wall Turbulence Intermittency

    2015-04-01

    Full Text Available In order to describe the phenomenon of intermittency in wall turbulence and, more particularly, the behaviour of moments  and and intermittency exponents ζP with the order p and distance to the wall, we developed a new geometrical framework called “entropic-skins geometry” based on the notion of scale-entropy which is here applied to an experimental database of boundary layer flows. Each moment has its own spatial multi-scale support Ωp (“skin”. The model assumes the existence of a hierarchy of multi-scale sets Ωp ranged from the “bulk” to the “crest”. The crest noted characterizes the geometrical support where the most intermittent (the highest fluctuations in energy dissipation occur; the bulk is the geometrical support for the whole range of fluctuations. The model assumes then the existence of a dynamical flux through the hierarchy of skins. The specific case where skins display a fractal structure is investigated. Bulk fractal dimension  and crest dimension  are linked by a scale-entropy flux defining a reversibility efficiency  (d is the embedding dimension. The model, initially developed for homogeneous and isotropic turbulent flows, is applied here to wall bounded turbulence where intermittency exponents are measured by extended self-similarity. We obtained for intermittency exponents the analytical expression with γ ≈ 0.36 in agreement with experimental results.

  6. Folding superfunnel to describe cooperative folding of interacting proteins.

    2016-07-01

    This paper proposes a generalization of the well-known folding funnel concept of proteins. In the funnel model the polypeptide chain is treated as an individual object not interacting with other proteins. Since biological systems are considerably crowded, protein-protein interaction is a fundamental feature during the life cycle of proteins. The folding superfunnel proposed here describes the folding process of interacting proteins in various situations. The first example discussed is the folding of the freshly synthesized protein with the aid of chaperones. Another important aspect of protein-protein interactions is the folding of the recently characterized intrinsically disordered proteins, where binding to target proteins plays a crucial role in the completion of the folding process. The third scenario where the folding superfunnel is used is the formation of aggregates from destabilized proteins, which is an important factor in case of several conformational diseases. The folding superfunnel constructed here with the minimal assumption about the interaction potential explains all three cases mentioned above.

    The advancement of neuroscience, perhaps one of the most information rich disciplines of all the life sciences, requires basic frameworks for organizing the vast amounts of data generated by the research community to promote novel insights and integrated understanding. Since Cajal, the neuron remains a fundamental unit of the nervous system, yet even with the explosion of information technology, we still have few comprehensive or systematic strategies for aggregating cell-level knowledge. Progress toward this goal is hampered by the multiplicity of names for cells and by lack of a consensus on the criteria for defining neuron types. However, through umbrella projects like the Neuroscience Information Framework (NIF) and the International Neuroinformatics Coordinating Facility (INCF), we have the opportunity to propose and implement an informatics infrastructure for establishing common tools and approaches to describe neurons through a standard terminology for nerve cells and a database (a Neuron Registry) where these descriptions can be deposited and compared. This article provides an overview of the problem and outlines a solution approach utilizing ontological characterizations. Based on illustrative implementation examples, we also discuss the need for consensus criteria to be adopted by the research community, and considerations on future developments. A scalable repository of neuron types will provide researchers with a resource that materially contributes to the advancement of neuroscience. PMID:22557965

    2010-01-01

    Using multivariate analysis, we created a hierarchical modeling process that describes how differently-scaled environmental factors interact to affect wetland-scale plant community organization in a system of small, isolated wetlands on Mount Desert Island, Maine. We followed the procedure: 1) delineate wetland groups using cluster analysis, 2) identify differently scaled environmental gradients using non-metric multidimensional scaling, 3) order gradient hierarchical levels according to spatiotem-poral scale of fluctuation, and 4) assemble hierarchical model using group relationships with ordination axes and post-hoc tests of environmental differences. Using this process, we determined 1) large wetland size and poor surface water chemistry led to the development of shrub fen wetland vegetation, 2) Sphagnum and water chemistry differences affected fen vs. marsh / sedge meadows status within small wetlands, and 3) small-scale hydrologic differences explained transitions between forested vs. non-forested and marsh vs. sedge meadow vegetation. This hierarchical modeling process can help explain how upper level contextual processes constrain biotic community response to lower-level environmental changes. It creates models with more nuanced spatiotemporal complexity than classification and regression tree procedures. Using this process, wetland scientists will be able to generate more generalizable theories of plant community organization, and useful management models. ?? Society of Wetland Scientists 2009.

    2014-12-01

    We study the canonical quantization of a bosonic string in presence of N twist fields. This generalizes the quantization of the twisted string in two ways: the in and out states are not necessarily twisted and the number of twist fields N can be bigger than 2. In order to quantize the theory we need to find the normal modes. Then we need to define a product between two modes which is conserved. Because of this we need to use the Klein-Gordon product and to separate the string coordinate into the classical and the quantum part. The quantum part has different boundary conditions than the original string coordinates but these boundary conditions are precisely those which make the operator describing the equation of motion self adjoint. The splitting of the string coordinates into a classical and quantum part allows the formulation of an improved overlap principle. Using this approach we then proceed in computing the generating function for the generic correlator with L untwisted operators and N (excited) twist fields for branes at angles. We recover as expected the results previously obtained using the path integral. This construction explains why these correlators are given by a generalization of the Wick theorem.

    Full Text Available Advanced mathematical model was used to capture the batch reactor characteristics of reacting compounds. The model was applied to batch reactor for the production of bio-diesel from palm and kapok oils. Results of the model were compared with experimental data in terms of conversion of transesterification reaction for the production of bio-diesel under unsteady state. A good agreement was obtained between our model predictions and the experimental data. Both experimental and modeling results showed that the conversion of triglycerides to methyl ester was affected by the process conditions. The transesterification process with temperature of about 70 oC, and methanol ratio to the triglyceride of about 5 times its stoichiometry, and the NAOH catalyst of wt 0.4%, appear to be acceptable process conditions for bio diesel process production from palm oil and kapok oil.

    As health care applications derived from human genetics research are likely to move increasingly from 'clinic to community', there is growing interest not just in how patients understand and take up health-related genetic information but also in the views of the wider population, as well as a range of professional groups. In this paper, issues relating public knowledge and public trust are raised and discussed in an attempt to move forward debates about public involvement in genomic research and the role of sociologists within interdisciplinary teams. As the field of public understanding of science has developed, we have seen a shift from a focus on the lack of scientific literacy as problem to a recognition of the range of different knowledges that people have and use as they confront science and technology in their everyday lives. As a mood for dialogue pervades many institutions in their relations with 'publics', attention must now be paid to the way in which knowledge and expertise is expressed, heard and acted upon in dialogic encounters. There is increasing concern about public trust in science and calls to increase public confidence, particularly through more open engagement with a range of publics. However, lack of trust or loss of confidence may be constructed as problems rather than reflecting empirical reality, where more complex relationships and attitudes prevail. Lack of trust is often privatized, deeply rooted in lived experience and routinely managed. Trust relations are generally characterized by ambivalence, uncertainty and risk, and are always provisional. Drawing on selected literature and empirical research to review and illustrate this field, this paper argues that scepticism or ambivalence on the part of publics are not necessarily problems to be overcome in the interest of scientific progress, but rather should be mobilized to enhance open and public debates about the nature and direction of genomics research, medicine, and the related

    The classical natural coordinate modeling method which removes the Euler angles and Euler parameters from the governing equations is particularly suitable for the sensitivity analysis and optimization of multibody systems. However, the formulation has so many principles in choosing the generalized coordinates that it hinders the implementation of modeling automation. A first order direct sensitivity analysis approach to multibody systems formulated with novel natural coordinates is presented. Firstly, a new selection method for natural coordinate is developed. The method introduces 12 coordinates to describe the position and orientation of a spatial object. On the basis of the proposed natural coordinates, rigid constraint conditions, the basic constraint elements as well as the initial conditions for the governing equations are derived. Considering the characteristics of the governing equations, the newly proposed generalized-α integration method is used and the corresponding algorithm flowchart is discussed. The objective function, the detailed analysis process of first order direct sensitivity analysis and related solving strategy are provided based on the previous modeling system. Finally, in order to verify the validity and accuracy of the method presented, the sensitivity analysis of a planar spinner-slider mechanism and a spatial crank-slider mechanism are conducted. The test results agree well with that of the finite difference method, and the maximum absolute deviation of the results is less than 3%. The proposed approach is not only convenient for automatic modeling, but also helpful for the reduction of the complexity of sensitivity analysis, which provides a practical and effective way to obtain sensitivity for the optimization problems of multibody systems.

  17. Describing rainfall in northern Australia using multiple climate indices

    Savanna landscapes are globally extensive and highly sensitive to climate change, yet the physical processes and climate phenomena which affect them remain poorly understood and therefore poorly represented in climate models. Both human populations and natural ecosystems are highly susceptible to precipitation variation in these regions due to the effects on water and food availability and atmosphere-biosphere energy fluxes. Here we quantify the relationship between climate phenomena and historical rainfall variability in Australian savannas and, in particular, how these relationships changed across a strong rainfall gradient, namely the North Australian Tropical Transect (NATT). Climate phenomena were described by 16 relevant climate indices and correlated against precipitation from 1900 to 2010 to determine the relative importance of each climate index on seasonal, annual and decadal timescales. Precipitation trends, climate index trends and wet season characteristics have also been investigated using linear statistical methods. In general, climate index-rainfall correlations were stronger in the north of the NATT where annual rainfall variability was lower and a high proportion of rainfall fell during the wet season. This is consistent with a decreased influence of the Indian-Australian monsoon from the north to the south. Seasonal variation was most strongly correlated with the Australian Monsoon Index, whereas yearly variability was related to a greater number of climate indices, predominately the Tasman Sea and Indonesian sea surface temperature indices (both of which experienced a linear increase over the duration of the study) and the El Niño-Southern Oscillation indices. These findings highlight the importance of understanding the climatic processes driving variability and, subsequently, the importance of understanding the relationships between rainfall and climatic phenomena in the Northern Territory in order to project future rainfall patterns in the

  18. Probabilistic models to describe the dynamics of migrating microbial communities.

    Directory of Open Access Journals (Sweden)

    Joanna L Schroeder

    Full Text Available In all but the most sterile environments bacteria will reside in fluid being transported through conduits and some of these will attach and grow as biofilms on the conduit walls. The concentration and diversity of bacteria in the fluid at the point of delivery will be a mix of those when it entered the conduit and those that have become entrained into the flow due to seeding from biofilms. Examples include fluids through conduits such as drinking water pipe networks, endotracheal tubes, catheters and ventilation systems. Here we present two probabilistic models to describe changes in the composition of bulk fluid microbial communities as they are transported through a conduit whilst exposed to biofilm communities. The first (discrete model simulates absolute numbers of individual cells, whereas the other (continuous model simulates the relative abundance of taxa in the bulk fluid. The discrete model is founded on a birth-death process whereby the community changes one individual at a time and the numbers of cells in the system can vary. The continuous model is a stochastic differential equation derived from the discrete model and can also accommodate changes in the carrying capacity of the bulk fluid. These models provide a novel Lagrangian framework to investigate and predict the dynamics of migrating microbial communities. In this paper we compare the two models, discuss their merits, possible applications and present simulation results in the context of drinking water distribution systems. Our results provide novel insight into the effects of stochastic dynamics on the composition of non-stationary microbial communities that are exposed to biofilms and provides a new avenue for modelling microbial dynamics in systems where fluids are being transported.

  19. Describing failure in geomaterials using second-order work approach

    Directory of Open Access Journals (Sweden)

    François Nicot

    2015-04-01

    Full Text Available Geomaterials are known to be non-associated materials. Granular soils therefore exhibit a variety of failure modes, with diffuse or localized kinematical patterns. In fact, the notion of failure itself can be confusing with regard to granular soils, because it is not associated with an obvious phenomenology. In this study, we built a proper framework, using the second-order work theory, to describe some failure modes in geomaterials based on energy conservation. The occurrence of failure is defined by an abrupt increase in kinetic energy. The increase in kinetic energy from an equilibrium state, under incremental loading, is shown to be equal to the difference between the external second-order work, involving the external loading parameters, and the internal second-order work, involving the constitutive properties of the material. When a stress limit state is reached, a certain stress component passes through a maximum value and then may decrease. Under such a condition, if a certain additional external loading is applied, the system fails, sharply increasing the strain rate. The internal stress is no longer able to balance the external stress, leading to a dynamic response of the specimen. As an illustration, the theoretical framework was applied to the well-known undrained triaxial test for loose soils. The influence of the loading control mode was clearly highlighted. It is shown that the plastic limit theory appears to be a particular case of this more general second-order work theory. When the plastic limit condition is met, the internal second-order work is nil. A class of incremental external loadings causes the kinetic energy to increase dramatically, leading to the sudden collapse of the specimen, as observed in laboratory.

    Full Text Available During the last decades the idea of entrepreneurship in public institutions has been the subject of intense debates, activities and academic research. The scopes of our article are to briefly underline the importance of developing an entrepreneurial spirit by presenting a case study from a Finnish local public administration and making aware the proactive aspect in the process of managing public institutions in Romania. Our hypotheses have been mainly of an interrogative nature. Hypothesis testing was achieved through the analysis of statistical data and conducting a set of sociological interviews with key people from Finnish institutions which were used in the survey. The results of the research emphasize that where there is an entrepreneurial behaviour with the local administration management, the community undergoes a process of conservation and development. The way in which they relate to community partners (such as entrepreneurs, non-profit organizations, citizens is essential to the entrepreneurial spirit within the local public institution.

    Among the greatest challenges facing the conservation of plants and animal species in protected areas are threats from a rapidly changing climate. An altered climate creates both challenges and opportunities for improving the management of protected areas in networks. Increasingly, quantitative tools like species distribution modeling are used to assess the performance of protected areas and predict potential responses to changing climates for groups of species, within a predictive framework. At larger geographic domains and scales, protected area network units have spatial geoclimatic properties that can be described in the gap analysis typically used to measure or aggregate the geographic distributions of species (stacked species distribution models, or S-SDM). We extend the use of species distribution modeling techniques in order to model the climate envelope (or “footprint”) of individual protected areas within a network of protected areas distributed across the 48 conterminous United States and managed by the US National Park System. In our approach we treat each protected area as the geographic range of a hypothetical endemic species, then use MaxEnt and 5 uncorrelated BioClim variables to model the geographic distribution of the climatic envelope associated with each protected area unit (modeling the geographic area of park units as the range of a species). We describe the individual and aggregated climate envelopes predicted by a large network of 163 protected areas and briefly illustrate how macroecological measures of geodiversity can be derived from our analysis of the landscape ecological context of protected areas. To estimate trajectories of change in the temporal distribution of climatic features within a protected area network, we projected the climate envelopes of protected areas in current conditions onto a dataset of predicted future climatic conditions. Our results suggest that the climate envelopes of some parks may be locally unique or

  10. Describing soil surface microrelief by crossover length and fractal dimension

    Directory of Open Access Journals (Sweden)

    E. Vidal Vázquez

    2007-05-01

    Full Text Available Accurate description of soil surface topography is essential because different tillage tools produce different soil surface roughness conditions, which in turn affects many processes across the soil surface boundary. Advantages of fractal analysis in soil microrelief assessment have been recognised but the use of fractal indices in practice remains challenging. There is also little information on how soil surface roughness decays under natural rainfall conditions. The objectives of this work were to investigate the decay of initial surface roughness induced by natural rainfall under different soil tillage systems and to compare the performances of a classical statistical index and fractal microrelief indices. Field experiments were performed on an Oxisol at Campinas, São Paulo State (Brazil. Six tillage treatments, namely, disc harrow, disc plow, chisel plow, disc harrow + disc level, disc plow + disc level and chisel plow + disc level were tested. Measurements were made four times, firstly just after tillage and subsequently with increasing amounts of natural rainfall. Duplicated measurements were taken per treatment and date, yielding a total of 48 experimental surfaces. The sampling scheme was a square grid with 25×25 mm point spacing and the plot size was 1350×1350 mm, so that each data set consisted of 3025 individual elevation points. Statistical and fractal indices were calculated both for oriented and random roughness conditions, i.e. after height reading have been corrected for slope and for slope and tillage tool marks. The main drawback of the standard statistical index random roughness, RR, lies in its no spatial nature. The fractal approach requires two indices, fractal dimension, D, which describes how roughness changes with scale, and crossover length, l, specifying the variance of surface microrelief at a reference scale. Fractal parameters D and l, were estimated by two independent self-affine models

    2012-01-01

    Full Text Available OBJECTIVE: The aim of this study was to evaluate some features of article titles from open access journals and to assess the possible impact of these titles on predicting the number of article views and citations. METHODS: Research articles (n = 423, published in October 2008 from all Public Library of Science (PLoS journals and from 12 Biomed Central (BMC journals were evaluated. Publication metrics (views and citations were analyzed in December 2011. The titles were classified according to their contents, namely methods-describing titles and results-describing titles. The number of title characters, title typology, the use of a question mark, reference to a specific geographical region, and the use of a colon or a hyphen separating different ideas within a sentence were analyzed to identify predictors of views and citations. A logistic regression model was used to identify independent title characteristics that could predict citation rates. RESULTS: Short-titled articles had higher viewing and citation rates than those with longer titles. Titles containing a question mark, containing a reference to a specific geographical region, and that used a colon or a hyphen were associated with a lower number of citations. Articles with results-describing titles were cited more often than those with methods-describing titles. After multivariate analysis, only a low number of characters and title typology remained as predictors of the number of citations. CONCLUSIONS: Some features of article titles can help predict the number of article views and citation counts. Short titles presenting results or conclusions were independently associated with higher citation counts. The findings presented here could be used by authors, reviewers, and editors to maximize the impact of articles in the scientific community.

    Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the  background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

    A significant literature identifies the policy, economic, health, and social challenges that confront released prisoners. This literature also describes the public health and public safety risks associated with prisoner reentry, provides recommendations for improving the reentry process, and describes the effectiveness of prison-based programs on recidivism rates. Public health and public safety risks are particularly significant in communities where large numbers of prisoners are released and few evidence-based services exist. The purpose of this article is to describe the public health and public safety risks that released prisoners experience when they reenter communities, and to discuss the social justice issues relevant for social work practice.

  8. The CRACK programme: a scientific alliance for bridging healthcare research and public health policies in Italy

    Directory of Open Access Journals (Sweden)

    Giovanni Corrao

    2013-09-01

    Full Text Available Healthcare utilisation databases, and other secondary data sources, have been used with growing frequency to assess health outcomes and healthcare interventions worldwide. Their increased popularity as a research tool is due to their timely availability, the large patient populations covered, low cost, and applicability for studying real-world clinical practice. Despite the need to measure Italian National Health Service performance both at regional and national levels, the wealth of good quality electronic data and the high standards of scientific research in this field, healthcare research and public health policies seem to progress along orthogonal dimensions in Italy. The main barriers to the development of evidence-based public health include the lack of understanding of evidence-based methodologies by policy makers, and of involvement of researchers in the policy process. The CRACK programme was launched by some academics from the Lombardy Region. By extensively using electronically stored data, epidemiologists, biostatisticians, pharmacologists and clinicians applied methods and evidence to several issues of healthcare research. The CRACK programme was based on their intention to remove barriers that thwart the process of bridging methods and findings from scientific journals to public health practice. This paper briefly describes aim, articulation and management of the CRACK programme, and discusses why it might find articulated application in Italy.

  16. Structure of electric double layers in capacitive systems and to what extent (classical) density functional theory describes it

    Science.gov (United States)

    Härtel, Andreas

    2017-10-01

    Ongoing scientific interest is aimed at the properties and structure of electric double layers (EDLs), which are crucial for capacitive energy storage, water treatment, and energy harvesting technologies like supercapacitors, desalination devices, blue engines, and thermocapacitive heat-to-current converters. A promising tool to describe their physics on a microscopic level is (classical) density functional theory (DFT), which can be applied in order to analyze pair correlations and charge ordering in the primitive model of charged hard spheres. This simple model captures the main properties of ionic liquids and solutions and it predicts many of the phenomena that occur in EDLs. The latter often lead to anomalous response in the differential capacitance of EDLs. This work constructively reviews the powerful theoretical framework of DFT and its recent developments regarding the description of EDLs. It explains to what extent current approaches in DFT describe structural ordering and in-plane transitions in EDLs, which occur when the corresponding electrodes are charged. Further, the review briefly summarizes the history of modeling EDLs, presents applications, and points out limitations and strengths in present theoretical approaches. It concludes that DFT as a sophisticated microscopic theory for ionic systems is expecting a challenging but promising future in both fundamental research and applications in supercapacitive technologies.

  18. The history of endemic Iberian ground beetle description (Insecta, Coleoptera, Carabidae): which species were described first?

    Science.gov (United States)

    Jiménez-Valverde, Alberto; Ortuño, Vicente M.

    2007-01-01

    iological correlates of species description dates can be used to predict the characteristics of yet-to-be-described species. Such information can be useful in the planning of biodiversity field surveys. This paper explores the influence of five factors—body size, geographic range size, geographic location, habitat and number of congeners—on the probability of description of endemic Iberian ground-beetles, and attempts to identify the effects of each factor, alone or in combination, through variation partitioning. Small-bodied and hypogean species were found to have been described later, as were those with smaller geographic ranges, while the number of congeners did not significantly affect description date. Additionally, Eastern hypogean species were described earlier than Western ones because of major lithology differences from east to west in the Iberian Peninsula, and concomitant geographic taxonomic bias. However, effects of each factor alone are quite small in comparison with effects of the combination of factors, due to their considerable correlation. Thus, "rarity", in its broadest sense, has been the determining factor of date of description of endemic Iberian ground-beetles. Previously, the technical difficulty encountered in the study of rare species retarded their description, whereas now they have become a "fashionable" object of study among carabidologists, due to the possibility of rapid publication. In order to improve the incomplete checklist of Iberian ground beetles it would be necessary to focus sampling efforts on marginal habitats and hypogean fauna.

    In this work, the optional public goods games with punishment are studied. By adopting the approximate best response dynamics, a micro model is given to explain the evolutionary process. Simultaneously, the magnitude of rationality is also considered. Under the condition of bounded rationality which provides a light to interpret phenomena in human society, the model leads to two types of equilibriums. One is the equilibrium without punishers and the other is the equilibrium including only punishers and cooperators. In addition, the effects of rationality on equilibriums are briefly investigated.

    Full Text Available The necessary work for developing a scientific publication is sometimes underestimated and requires the effective participation of many players to obtain a result in good standard. Initially it depends upon the determination of the authors that decide to write the scientific article. Scientific writing is a very challenging and time consuming task, but at the same time essential for any scientist. A published scientific article is unquestionably one of the main indicators of scientific production, especially if published in a qualified scientific journal with highly qualified editorial committee and strict peer review procedure. By looking at evaluation criteria for scientific production of the several Thematic Scientific Committees of the Brazilian Council for Scientific and Technological Development (CNPq it becomes clear publications in scientific journals that has certified quality is the most important item in the evaluation of a scientist production.

Not only is this specialty important for its role in commissioning services, it is crucial for the identification of vulnerable groups in society and ensuring dental services are acceptable and assessable for these populations. Dental public health also addresses the social determinants of health in its approach, acknowledging the impact of these in perpetuating inequalities and looking for multisectoral approaches to their management. This article also looks at the lack of appreciation for these determinants in dental foundation training and how a change in the structure of the programme could both address this and the current shortage of places.

    Adolescent dating violence is increasingly recognized as a public health problem. Our qualitative investigation sought input from urban, African-American adolescents at risk for dating violence concerning (Tjaden and Thoennes in Full report of the prevelance, incidence, and consequences of violence against women: findings from the national violence against women survey. US Department of Justice, Washington, DC, 2000) dating violence descriptions, (WHO multi-country study on women's health and domestic violence against women: Summary report of initial results on prevalence, health outcomes and women's responses.

Bureau of Justice Statistics, US Department of Justice, Office of Justice Programs, Washington, DC, 2007) recommendations for a teen dating violence resource center. Four focus groups were conducted with urban, African American adolescents (n = 32) aged 13-24 recruited from an urban adolescent clinic's community outreach partners. Qualitative analysis was conducted. Participants assigned a wide range of meanings for the term "relationship drama", and used dating violence using language not typically heard among adults, e.g., "disrespect". Participants described preferences for turning to family or friends before seeking formal services for dating violence, but reported barriers to their ability to rely on these informal sources. When asked to consider formal services, they described their preferred resource center as confidential and safe, with empathetic, non-judgmental staff. Teens also gave insight into preferred ways to outreach and publicize dating violence resources. Findings inform recommendations for youth-specific tailoring of violence screening and intervention efforts. Current evidence that slang terms, i.e., "drama", lack specificity suggests that they should not be integrated within screening protocols

    This special issue of the Journal of Genetic Counseling is dedicated to public health genetics and genomics. The seventeen papers featured in this issue span such topics as genetic counselors in public health roles, newborn screening, population screening, ethics, and health beliefs and behaviors. In this introduction to the special issue, we review some history of public health genetics and genomics, present the Centers for Disease Control and Prevention's "10 Essential Public Health Services" with associated genetics specific recommendations and priorities, and briefly overview how each article ties into the world of public health genetics and genomics. We hope this issue encourages genetic counselors to visualize their ever expanding and important roles in public health genetics and genomics, as well as their contributions to improving population health.

    Evidence-based policy is being encouraged in all areas of public service ( Black 2001 ). Unprecedented federal legislation reflects a faith in science "as a force for improved public policy" ( Feuer et al. 2002 ). The objective of evidence-based policy is to use scientific research to drive decision making. Thus, the link between social science research and public policy seems to be a natural one. The purpose of this chapter is to address how psychological science in general, and clinical psychology in particular, can be of use to public policy makers. We discuss how psychological science can be relevant and applicable to informing policy, and we describe the role clinical scientists might play in generating, disseminating, and implementing that information. We also note distinct limitations on the usefulness of psychological research in driving public policy. We discuss some pitfalls and recommend areas where clinical psychology might best serve public policy.

  17. Conceptual framework for describing selected urban and community impacts of federal energy policies

    Energy Technology Data Exchange (ETDEWEB)

    Morris, F.A,; Marcus, A.A.; Keller, D.

    1980-06-01

    A conceptual framework is presented for describing selected urban and community impacts of Federal energy policies. The framework depends on a simple causal model. The outputs of the model are impacts, changes in the state of the world of particular interest to policymakers. At any given time, a set of determinants account for the state of the world with respect to an impact category. Application of the model to a particular impact category requires: establishing a definition and measure for the impact category and identifying the determinants of these impacts. Analysis of the impact of a particular policy requires the following: identifying the policy and its effects (as estimated by others), isolating any effects that themselves constitute an urban and community impact, identifying any effects that change the value of determinants, and describing the impact with reference to the new values of determinants. This report provides a framework for these steps. Three impacts addressed are: neighborhood stability, housing availability, and quality and availability of public services. In each chapter, a definition and measure for the impact are specified; its principal determinants are identified; how the causal model can be used to estimate impacts by applying it to three illustrative Federal policies (domestic oil price decontrol, building energy performance standards, and increased Federal aid for mass transit) is demonstrated.

    Full Text Available Every day, in urban areas, the mobility of people and goods forms inner urban transportation. When urban transportation is carried in the form of public transportation, it becomes a public service. The urban public transport is one of the important services for all citizens since it is a public service provision. This service is provided by local government and it has been offered as a service without any distinctions between young, old, children, men, women, disabled, employee or retired or briefly to the society.  Additionally, traffic congestion and the expence of owing and maintaining vehicles increase public transport usage in cities.

  20. Population Dynamics P system (PDP) models: a standardized protocol for describing and applying novel bio-inspired computing tools.

    Science.gov (United States)

    Colomer, Maria Àngels; Margalida, Antoni; Pérez-Jiménez, Mario J

    2013-01-01

    Today, the volume of data and knowledge of processes necessitates more complex models that integrate all available information. This handicap has been solved thanks to the technological advances in both software and hardware. Computational tools available today have allowed developing a new family of models, known as computational models. The description of these models is difficult as they can not be expressed analytically, and it is therefore necessary to create protocols that serve as guidelines for future users. The Population Dynamics P systems models (PDP) are a novel and effective computational tool to model complex problems, are characterized by the ability to work in parallel (simultaneously interrelating different processes), are modular and have a high computational efficiency. However, the difficulty of describing these models therefore requires a protocol to unify the presentation and the steps to follow. We use two case studies to demonstrate the use and implementation of these computational models for population dynamics and ecological process studies, discussing briefly their potential applicability to simulate complex ecosystem dynamics.

  2. Exploring early public responses to geoengineering.

    Pidgeon, Nick; Corner, Adam; Parkhill, Karen; Spence, Alexa; Butler, Catherine; Poortinga, Wouter

    2012-09-13

    Proposals for geoengineering the Earth's climate are prime examples of emerging or 'upstream' technologies, because many aspects of their effectiveness, cost and risks are yet to be researched, and in many cases are highly uncertain. This paper contributes to the emerging debate about the social acceptability of geoengineering technologies by presenting preliminary evidence on public responses to geoengineering from two of the very first UK studies of public perceptions and responses. The discussion draws upon two datasets: qualitative data (from an interview study conducted in 42 households in 2009), and quantitative data (from a subsequent nationwide survey (n=1822) of British public opinion). Unsurprisingly, baseline awareness of geoengineering was extremely low in both cases. The data from the survey indicate that, when briefly explained to people, carbon dioxide removal approaches were preferred to solar radiation management, while significant positive correlations were also found between concern about climate change and support for different geoengineering approaches. We discuss some of the wider considerations that are likely to shape public perceptions of geoengineering as it enters the media and public sphere, and conclude that, aside from technical considerations, public perceptions are likely to prove a key element influencing the debate over questions of the acceptability of geoengineering proposals.

    This paper describes a new, public-domain interface for modeling flow, sediment transport and morphodynamics in rivers and other geophysical flows. The interface is named after the International River Interface Cooperative (iRIC), the group that constructed the interface and many of the current solvers included in iRIC. The interface is entirely free to any user and currently houses thirteen models ranging from simple one-dimensional models through three-dimensional large-eddy simulation models. Solvers are only loosely coupled to the interface so it is straightforward to modify existing solvers or to introduce other solvers into the system. Six of the most widely-used solvers are described in detail including example calculations to serve as an aid for users choosing what approach might be most appropriate for their own applications. The example calculations range from practical computations of bed evolution in natural rivers to highly detailed predictions of the development of small-scale bedforms on an initially flat bed. The remaining solvers are also briefly described. Although the focus of most solvers is coupled flow and morphodynamics, several of the solvers are also specifically aimed at providing flood inundation predictions over large spatial domains. Potential users can download the application, solvers, manuals, and educational materials including detailed tutorials at www.-i-ric.org. The iRIC development group encourages scientists and engineers to use the tool and to consider adding their own methods to the iRIC suite of tools.

SE, as all entrepreneurship practices, operates by social and economic forces (limiting ourselves to those here), and generates social and economic outcomes (amongst others). Its second half, however, dominates the concept of SE, and our analysis seek to remedy this imbalance......In this paper we want to affirm the desiring-social-change that we find in practices presently represented by theorists and policy-makers as examples of ‘social entrepreneurship’ (SE). We do this as an attempt to intensify the presence of the social and sociality in today's discourse...... by focusing on the social productivity of entrepreneurship, on entrepreneurship desiring social change. We suggest ‘public entrepreneurship’ might grasp this as a more balanced concept that will also support a more precise analysis of the entrepreneurship–society relationship....

  9. Rethinking public space: A new lexicon for design

    Directory of Open Access Journals (Sweden)

    Edward Robbins

    2008-01-01

    Full Text Available In the debate about the importance and the design of well planned public open spaces, it is critical that we address the meaning and implications of the notions of public space. Most definitions are fundamentally overdetermined and fraught with contradictions and ambiguities. Equally as critical, for designers especially, is that these definitions of public space provide little guidance for creating successful public places. The paper’s author examines these definitions and the issues they pose and goes on to argue that what is needed is a new lexicon for addressing public space. Such a lexicon is briefly proposed. Such a lexicon, it is argued, would provide a more useful and broader discourse about what qualities define place and its political and spatial implications. In so doing it would also offer better guidance and insights for the design of social spaces.

  15. What is a Bristow-Latarjet procedure? A review of the described operative techniques and outcomes.

    Science.gov (United States)

    Cowling, P D; Akhtar, M A; Liow, R Y L

    2016-09-01

    A variety of operative techniques have been described as under the term 'Bristow-Latarjet' procedure. This review aims to define the original procedure, and compare the variation in techniques described in the literature, assessing any effect on clinical outcomes. A systematic review of 24 studies was performed to compare specific steps of the technique (coracoid osteotomy site, subscapularis approach, orientation and position of coracoid graft fixation and fixation method, additional labral and capsular repair) and detect any effect this variability had on outcomes. Overall recurrence rate was 5.36% (2.94% to 43%). Half of the studies performed the procedure for recurrent shoulder instability, with only five studies documenting glenoid bone loss as an indication: 12 studies used the procedure as the primary surgical intervention for recurrent instability. No change in outcome was noted when examining variation in the coracoid osteotomy site, the fixation site on the scapular neck, the fixation method or whether a capsular repair was also performed. Performing a horizontal split in subscapularis may preserve external rotation compared with performing a tenotomy. This is the first review to examine various operative techniques of the Bristow-Latarjet procedure, and their effect on outcome. We found that other than the approach through subscapularis, outcome was independent of the surgical technique, and depended more on patient selection. We would commend future publications on this procedure to provide a detailed description of the surgical technique, and as a minimum present rates of recurrence as an outcome measure.

    2015-12-01

    Full Text Available Abstract The aim of this study was to assess the hepatotoxicity cases described in the literature, attributed to the consumption of Herbalife(r products, and to determine whether a causal relationship exists between the reported cases of liver injury and the use of these products. A literature search was performed on the PubMed, LILACS and PAHO databases. Seven publications reporting a total of 53 cases of hepatotoxicity linked to the use of Herbalife(r products were retrieved. All of the studies lacked sufficient information to some degree, whether related to patients' history, concomitant use of medication and/or other compounds (including alcohol, observations on interrupted use (dechallenge, results found with markers, viral serology and autoantibodies or observations concerning re-exposure to the products. In addition to these items, the lack of clear information on the type of products evaluated and their respective composition is an important factor to be considered. Furthermore, data quality was also questionable due to the presence of confounding factors, absence of proper exclusion of alternative explanations, and the use of questionable methods for attributing causality. Hence, an association between hepatotoxicity and consumption of these products cannot be proven based on the data collected and rigorous scientific analysis.

    The emphasis of a draft on the reform of energy legislation from the Federal Ministry of Economics and the emphasis of the general discussion is the so-called third party access and unbundling as well as the new approach to the granting of regional monopolies. In the final analysis the point of all these suggestions is to unbundle supplies and make sure that more competition creates more efficiency. This contribution looks at the empirical aspects of the problem. Some public power supply companies in Germany were selected in order to identify and describe inefficiencies of public power supply in Germany. Part two briefly describes the situation on the sector of ``public power supply`` which the emphasis on the commitment of the public. Part three describes the basics of data envelopment analysis which is then used in part 4 in order to analyse power suppliers. A distinction is made between private and public industry analysis. Part 5 contains some conclusions.

    This paper offers a North American perspective on the possible reaction of the general public to regulatory instruments addressing energy consumption, and by implication, carbon emissions. Its purpose is to reflect on some of the lessons learnt from research on consumer behaviour undertaken by the author and colleagues in the wake of the oil shortages of 1973 (OPEC embargo) and 1979 (interruption of Iranian production). The paper does not, therefore, provide an extensive review of related literature. It first outlines very briefly the policy context of the past 30 years and the classes of transport energy demand restraint policies of the 1970s and 1980s. It then describes some key lessons from our research during those two decades and concludes with some speculation on their relevance to demand-side management that is motivated by concerns over greenhouse gas emissions.

    Within the ICSTI Insights Series we offer three articles on the 'living publication' that is already available to practitioners in the important field of crystal structure determination and analysis. While the specific examples are drawn from this particular field, we invite readers to draw parallels in their own fields of interest. The first article describes the present state of the crystallographic living publication, already recognized by an ALPSP (Association of Learned and Professional Society Publishers) Award for Publishing Innovation in 2006. The second article describes the potential impact on the record of science as greater post-publication analysis becomes more common within currently accepted data deposition practices, using processed diffraction data as the starting point. The third article outlines a vision for the further improvement of crystallographic structure reports within potentially achievable enhanced data deposition practices, based upon raw (unprocessed) diffraction data. The IUCr in its Commissions and Journals has for many years emphasized the importance of publications being accompanied by data and the interpretation of the data in terms of atomic models. This has been followed as policy by numerous other journals in the field and its cognate disciplines. This practice has been well served by databases and archiving institutions such as the Protein Data Bank (PDB), the Cambridge Crystallographic Data Centre (CCDC), and the Inorganic Crystal Structure Database (ICSD). Normally the models that are archived are interpretations of the data, consisting of atomic coordinates with their displacement parameters, along with processed diffraction data from X-ray, neutron or electron diffraction studies. In our current online age, a reader can not only consult the printed word, but can display and explore the results with molecular graphics software of exceptional quality. Furthermore, the routine availability of processed diffraction

    Knowledge synthesis refers to the integration of findings from individual research studies on a given topic or question into the global knowledge base. The application of knowledge synthesis methods, particularly systematic reviews and meta-analysis, has increased considerably in the agri-food public health sector over the past decade and this trend is expected to continue. The objectives of our review were: (1) to describe the most promising knowledge synthesis methods and their applicability in agri-food public health, and (2) to summarize the recent advancements, challenges, and opportunities in the use of systematic review and meta-analysis methods in this sector. We performed a structured review of knowledge synthesis literature from various disciplines to address the first objective, and used comprehensive insights and experiences in applying these methods in the agri-food public health sector to inform the second objective. We describe five knowledge synthesis methods that can be used to address various agri-food public health questions or topics under different conditions and contexts. Scoping reviews describe the main characteristics and knowledge gaps in a broad research field and can be used to evaluate opportunities for prioritizing focused questions for related systematic reviews. Structured rapid reviews are streamlined systematic reviews conducted within a short timeframe to inform urgent decision-making. Mixed-method and qualitative reviews synthesize diverse sources of contextual knowledge (e.g. socio-cognitive, economic, and feasibility considerations). Systematic reviews are a structured and transparent method used to summarize and synthesize literature on a clearly-defined question, and meta-analysis is the statistical combination of data from multiple individual studies. We briefly describe and discuss key advancements in the use of systematic reviews and meta-analysis, including: risk-of-bias assessments; an overall quality

    When a target is flanked by distractors, it becomes more difficult to identify. In the periphery, this crowding effect extends over a wide range of target-flanker separations, called the spatial extent of interaction (EoI). A recent study showed that the EoI dramatically increases in size for short presentation durations (Chung & Mansfield, 2009). Here we investigate this duration-EoI relation in greater detail and show that (a) it holds even when visibility of the unflanked target is equated for different durations, (b) the function saturates for durations shorter than 30 to 80 ms, and (c) the largest EoIs represent a critical spacing greater than 50% of eccentricity. We also investigated the effect of same or different polarity for targets and flankers across different presentation durations. We found that EoIs for target and flankers having opposite polarity (one white, the other black) show the same temporal pattern as for same polarity stimuli, but are smaller at all durations by 29% to 44%. The observed saturation of the EoI for short-duration stimuli suggests that crowding follows the locus of temporal integration. Overall, the results constrain theories that map crowding zones to fixed spatial extents or to lateral connections of fixed length in the cortex.

Firstly, "Tang Ye Jing Fa" is the earliest book which marks the rudiment of traditional Chinese medicine dispensing. Secondly, traditional Chinese medicine dispensing theory formed in "Shen Nong's herbal classic". Thirdly, Zhang Zhongjing's "Treatise on Febrile Diseases" marked the formation of Chinese medicine dispensing skills. Lastly, Provisions in Tang Dynasty law marks the development of traditional Chinese medicine dispensing.

  5. Just one look: Direct gaze briefly disrupts visual working memory.

    Science.gov (United States)

    Wang, J Jessica; Apperly, Ian A

    2017-04-01

    Direct gaze is a salient social cue that affords rapid detection. A body of research suggests that direct gaze enhances performance on memory tasks (e.g., Hood, Macrae, Cole-Davies, & Dias, Developmental Science, 1, 67-71, 2003). Nonetheless, other studies highlight the disruptive effect direct gaze has on concurrent cognitive processes (e.g., Conty, Gimmig, Belletier, George, & Huguet, Cognition, 115(1), 133-139, 2010). This discrepancy raises questions about the effects direct gaze may have on concurrent memory tasks. We addressed this topic by employing a change detection paradigm, where participants retained information about the color of small sets of agents. Experiment 1 revealed that, despite the irrelevance of the agents' eye gaze to the memory task at hand, participants were worse at detecting changes when the agents looked directly at them compared to when the agents looked away. Experiment 2 showed that the disruptive effect was relatively short-lived. Prolonged presentation of direct gaze led to recovery from the initial disruption, rather than a sustained disruption on change detection performance. The present study provides the first evidence that direct gaze impairs visual working memory with a rapidly-developing yet short-lived effect even when there is no need to attend to agents' gaze.

    Ukraine has an advanced infrastructure providing its scientists with the support to take their skills in scientific space and astronomical research (some historical comments and present status will be briefly given). Nevertheless, the general understanding on what is the role of space sciences in development of the Ukrainian economy and society does not be yet in line with the high profile of space sciences. To improve this situation, the Space Research Council of the National Academy of Sciences and the Ukrainian Astronomical Association have supported the issues of special publications in these fields, namely the "Our sky" and "Pulsar" magazines, the special translated edition of the "Magnificent cosmos", the "Ukraine in constellation of space states of the world" special edition, moreover, the special movies dedicated to the well-known scientists and designers have been produced as well as various exhibitions and other PR actions have been organized. Paper will be devoted to the study of public reaction on this action.

    Ethnopharmacological research investigates the plants and other medicinal and toxic substances utilized by different traditional populations. One approach in this field is a literature search of the available publications on medicinal plants. The purpose of the current study was to select plants with psychoactive effects described in a Brazilian literary work written by Pio Correa in 1926. Those mentioned plants were classified in accordance with their indications for use as stimulants and depressors of the central nervous system. For the phytochemical study herein, we researched these species via a database search, and all the obtained information was compiled into a new database to analyze possible correlations between the chemical compounds and the psychoactive categories. Of the 813 plants searched in the literary work, 104 presented chemical data in the scientific periodicals consulted. Seventy-five of them belong to the stimulant category, while 31 are depressors and two of them belong to both categories. Phenols and flavonoids were the main compounds observed in plants of both categories, though at different frequencies. Monoterpenes (29.9%) and sesquiterpenes (28.6%) were also observed in plants from the stimulant category, while 25.8% of plants from the depressor category were comprised of carotenoids and 22.6% of steroids. The main specific compounds were identified as ferulic acid, α-pinene, limonene, α-humulene and kaempferol among the stimulant plants. Otherwise, in depressor plants were characterized caffeic acid, kaempferol, quercetin, β-carotene, physalins and withanolides as specific compounds. The association between ethnopharmacological and chemotaxonomic data, as presented in this study, could support plant selection in further investigations by research groups whose studies focus on psychoactive plants as potential therapeutics.

  11. ILexicOn: toward an ECD-compliant interlingual lexical ontology described with semantic web formalisms

    CERN Document Server

    Lefrançois, Maxime

    2012-01-01

    We are interested in bridging the world of natural language and the world of the semantic web in particular to support natural multilingual access to the web of data. In this paper we introduce a new type of lexical ontology called interlingual lexical ontology (ILexicOn), which uses semantic web formalisms to make each interlingual lexical unit class (ILUc) support the projection of its semantic decomposition on itself. After a short overview of existing lexical ontologies, we briefly introduce the semantic web formalisms we use. We then present the three layered architecture of our approach: i) the interlingual lexical meta-ontology (ILexiMOn); ii) the ILexicOn where ILUcs are formally defined; iii) the data layer. We illustrate our approach with a standalone ILexicOn, and introduce and explain a concise human-readable notation to represent ILexicOns. Finally, we show how semantic web formalisms enable the projection of a semantic decomposition on the decomposed ILUc.

    Public health policy works best when grounded in firm public health standards of evidence and widely shared social values. In this article, we argue for incorporating a specific method of ethical deliberation--deliberative public bioethics--into public health. We describe how deliberative public bioethics is a method of engagement that can be helpful in public health. Although medical, research, and public health ethics can be considered some of what bioethics addresses, deliberative public bioethics offers both a how and where. Using the Human Genome Project Ethical, Legal, and Social Implications program as an example of effective incorporation of deliberative processes to integrate ethics into public health policy, we examine how deliberative public bioethics can integrate both public health and bioethics perspectives into three areas of public health practice: research, education, and health policy. We then offer recommendations for future collaborations that integrate deliberative methods into public health policy and practice.

    This paper explores the determinants of pension funding in the public sector. We formulate and test several hypotheses about the determinants of public employer pension funding practices, using a new data set describing financial and other characteristics of state, local, and teacher plans. The data show that, on average, public sector pension plans were relatively well-funded during the late 1980s. There were, however, wide variations in funding practices in our sample. Our analysis of these...

  7. A comparison of macroscopic models describing the collective response of sedimenting rod-like particles in shear flows

    KAUST Repository

    Helzel, Christiane

    2016-07-22

    We consider a kinetic model, which describes the sedimentation of rod-like particles in dilute suspensions under the influence of gravity, presented in Helzel and Tzavaras (submitted for publication). Here we restrict our considerations to shear flow and consider a simplified situation, where the particle orientation is restricted to the plane spanned by the direction of shear and the direction of gravity. For this simplified kinetic model we carry out a linear stability analysis and we derive two different nonlinear macroscopic models which describe the formation of clusters of higher particle density. One of these macroscopic models is based on a diffusive scaling, the other one is based on a so-called quasi-dynamic approximation. Numerical computations, which compare the predictions of the macroscopic models with the kinetic model, complete our presentation.

  20. The living publication

    Energy Technology Data Exchange (ETDEWEB)

    Terwilliger, Thomas C. [Los Alamos National Laboratory

    2012-06-04

    Within the ICSTI Insights Series we offer three articles on the 'living publication' that is already available to practitioners in the important field of crystal structure determination and analysis. While the specific examples are drawn from this particular field, we invite readers to draw parallels in their own fields of interest. The first article describes the present state of the crystallographic living publication, already recognized by an ALPSP (Association of Learned and Professional Society Publishers) Award for Publishing Innovation in 2006. The second article describes the potential impact on the record of science as greater post-publication analysis becomes more common within currently accepted data deposition practices, using processed diffraction data as the starting point. The third article outlines a vision for the further improvement of crystallographic structure reports within potentially achievable enhanced data deposition practices, based upon raw (unprocessed) diffraction data. The IUCr in its Commissions and Journals has for many years emphasized the importance of publications being accompanied by data and the interpretation of the data in terms of atomic models. This has been followed as policy by numerous other journals in the field and its cognate disciplines. This practice has been well served by databases and archiving institutions such as the Protein Data Bank (PDB), the Cambridge Crystallographic Data Centre (CCDC), and the Inorganic Crystal Structure Database (ICSD). Normally the models that are archived are interpretations of the data, consisting of atomic coordinates with their displacement parameters, along with processed diffraction data from X-ray, neutron or electron diffraction studies. In our current online age, a reader can not only consult the printed word, but can display and explore the results with molecular graphics software of exceptional quality. Furthermore, the routine availability of processed diffraction

  1. Describing the Prevalence of Neural Tube Defects Worldwide: A Systematic Literature Review.

    Directory of Open Access Journals (Sweden)

    Ibrahim Zaganjor

    Full Text Available Folate-sensitive neural tube defects (NTDs are an important, preventable cause of morbidity and mortality worldwide. There is a need to describe the current global burden of NTDs and identify gaps in available NTD data.We conducted a systematic review and searched multiple databases for NTD prevalence estimates and abstracted data from peer-reviewed literature, birth defects surveillance registries, and reports published between January 1990 and July 2014 that had greater than 5,000 births and were not solely based on mortality data. We classified countries according to World Health Organization (WHO regions and World Bank income classifications. The initial search yielded 11,614 results; after systematic review we identified 160 full text manuscripts and reports that met the inclusion criteria. Data came from 75 countries. Coverage by WHO region varied in completeness (i.e., % of countries reporting as follows: African (17%, Eastern Mediterranean (57%, European (49%, Americas (43%, South-East Asian (36%, and Western Pacific (33%. The reported NTD prevalence ranges and medians for each region were: African (5.2-75.4; 11.7 per 10,000 births, Eastern Mediterranean (2.1-124.1; 21.9 per 10,000 births, European (1.3-35.9; 9.0 per 10,000 births, Americas (3.3-27.9; 11.5 per 10,000 births, South-East Asian (1.9-66.2; 15.8 per 10,000 births, and Western Pacific (0.3-199.4; 6.9 per 10,000 births. The presence of a registry or surveillance system for NTDs increased with country income level: low income (0%, lower-middle income (25%, upper-middle income (70%, and high income (91%.Many WHO member states (120/194 did not have any data on NTD prevalence. Where data are collected, prevalence estimates vary widely. These findings highlight the need for greater NTD surveillance efforts, especially in lower-income countries. NTDs are an important public health problem that can be prevented with folic acid supplementation and fortification of staple foods.

  2. Provenance of things - describing geochemistry observation workflows using PROV-O

    Science.gov (United States)

    Cox, S. J. D.; Car, N. J.

    2015-12-01

    Geochemistry observations typically follow a complex preparation process after sample retrieval from the field. Description of these are required to allow readers and other data users to assess the reliability of the data produced, and to ensure reproducibility. While laboratory notebooks are used for private record-keeping, and laboratory information systems (LIMS) on a facility basis, this data is not generally published, and there are no standard formats for transfer. And while there is some standardization of workflows, this is often scoped to a lab, or an instrument. New procedures and workflows are being developed continually - in fact this is a key expectation in the development of the science. Thus formalization of the description of sample preparation and observations must be both rigorous and flexible. We have been exploring the use of the W3C Provenance model (PROV) to capture complete traces, including both the real world things and the data generated. PROV has a core data model that distinguishes between entities, agents and activities involved in producing a piece of data or thing in the world. While the design of PROV was primarily conditioned by stories concerning information resources, application is not restricted to the production of digital or information assets. PROV allowing a comprehensive trace of predecessor entities and transformations at any level of detail. In this paper we demonstrate the use of PROV for describing specimens managed for scientific observations. Two examples are considered: a geological sample which undergoes a typical preparation process for measurements of the concentration of a particular chemical substance, and the collection, taxonomic classification and eventual publication of an insect specimen. PROV enables the material that goes into the instrument to be linked back to the sample retrieved in the field. This complements the IGSN system, which focuses on registration of field sample identity to support the

    2007-06-01

    Each year, infection with Human Papillomavirus (HPV) leads to millions of abnormal Pap smears and thousands of cases of cervical cancer in the US. Throughout the developing world, where Pap smears are less common, HPV is a leading cause of cancer death among women. So when the international pharmaceutical giant Merck developed a vaccine that could prevent infection with several key strains of HPV, the public health community was anxious to celebrate a major advance. But then marketing and lobbying got in the way. Merck chose to pursue an aggressive lobbying campaign, trying to make its new vaccine mandatory for young girls. The campaign stoked public mistrust about how vaccines come to be mandated, and now it's not just Merck's public image that has taken a hit. The public health community has also been affected. What is the lesson to be learned from this story? Public health communication relies on public trust.

  11. Computational methods for describing the laser-induced mechanical response of tissue

    Energy Technology Data Exchange (ETDEWEB)

    Trucano, T.; McGlaun, J.M.; Farnsworth, A.

    1994-02-01

    Detailed computational modeling of laser surgery requires treatment of the photoablation of human tissue by high intensity pulses of laser light and the subsequent thermomechanical response of the tissue. Three distinct physical regimes must be considered to accomplish this: (1) the immediate absorption of the laser pulse by the tissue and following tissue ablation, which is dependent upon tissue light absorption characteristics; (2) the near field thermal and mechanical response of the tissue to this laser pulse, and (3) the potential far field (and longer time) mechanical response of witness tissue. Both (2) and (3) are dependent upon accurate constitutive descriptions of the tissue. We will briefly review tissue absorptivity and mechanical behavior, with an emphasis on dynamic loads characteristic of the photoablation process. In this paper our focus will center on the requirements of numerical modeling and the uncertainties of mechanical tissue behavior under photoablation. We will also discuss potential contributions that computational simulations can make in the design of surgical protocols which utilize lasers, for example, in assessing the potential for collateral mechanical damage by laser pulses.

    2005-01-01

    This article explores public relations effectiveness in public health institutions. First, the two major elements that comprise public relations effectiveness are discussed: reputation management and stakeholder relations. The factors that define effective reputation management are examined, as are the roles of issues and crisis management in building and maintaining reputation. The article also examines the major facets of stakeholder relations, including an inventory of stakeholder linkages and key audiences, such as the media. Finally, methods of evaluating public relations effectiveness at both the program level and the institutional level are explored.

    In 2003, 11 public health epidemiologists were placed in North Carolina's largest hospitals to enhance communication between public health agencies and healthcare systems for improved emergency preparedness. We describe the specific services public health epidemiologists provide to local health departments, the North Carolina Division of Public Health, and the hospitals in which they are based, and assess the value of these services to stakeholders. We surveyed and/or interviewed public health epidemiologists, communicable disease nurses based at local health departments, North Carolina Division of Public Health staff, and public health epidemiologists' hospital supervisors to 1) elicit the services provided by public health epidemiologists in daily practice and during emergencies and 2) examine the value of these services. Interviews were transcribed and imported into ATLAS.ti for coding and analysis. Descriptive analyses were performed on quantitative survey data. Public health epidemiologists conduct syndromic surveillance of community-acquired infections and potential bioterrorism events, assist local health departments and the North Carolina Division of Public Health with public health investigations, educate clinicians on diseases of public health importance, and enhance communication between hospitals and public health agencies. Stakeholders place on a high value on the unique services provided by public health epidemiologists. Public health epidemiologists effectively link public health agencies and hospitals to enhance syndromic surveillance, communicable disease management, and public health emergency preparedness and response. This comprehensive description of the program and its value to stakeholders, both in routine daily practice and in responding to a major public health emergency, can inform other states that may wish to establish a similar program as part of their larger public health emergency preparedness and response system.

    Community engagement in public health policy is easier said than done. One reason is that public health policy is produced in a complex process resulting in policies that may appear not to link up to citizen perspectives. We therefore address the central question as to whether citizen engagement in knowledge production could enable inclusive health policy making. Building on non-health work fields, we describe different types of citizen engagement in scientific research, or 'Citizen Science'. We describe the challenges that Citizen Science poses for public health, and how these could be addressed. Despite these challenges, we expect that Citizen Science or similar approaches such as participatory action research and 'popular epidemiology' may yield better knowledge, empowered communities, and improved community health. We provide a draft framework to enable evaluation of Citizen Science in practice, consisting of a descriptive typology of different kinds of Citizen Science and a causal framework that shows how Citizen Science in public health might benefit both the knowledge produced as well as the 'Citizen Scientists' as active participants.

    Teymurian, F.; Alesheikh, A. A.; Alimohammadi, A.; Sadeghi-Niaraki, A.

    2013-09-01

    Recent advances in information technology have made geographic information system (GIS) a powerful and affordable tool for planning and decision making in various fields such as the public transportation. These technologies such as the social network (e.g. face-book, twitter), new technologies such as ubiquitous, mobile, Web 2.0, geo tagging and RFID can help to create better shapes and forms of the communication and geo-collaboration for public. By using these, user-generated content and spatial information can be easily and quickly produced and shared in a dynamic, interactive, multimedia and distributed environment. The concept of volunteered geographic information (VGI) has been introduced by the transaction from consultation to content interaction. VGI describes any type of content that has a geographic element and has been voluntarily collected. In other words, ordinary users; without a professional training, can participate in generating and using the spatial information. As a result, the gaps between the producers and users of GIS and spatial information, has been considerably reduced. Public transportation is one of the most important elements of the transportation system. Rapid growth of the cities has resulted in high increase of demand for the public transportation which created new challenges. Improvement of the desirability of public transportation can increase its efficiency, reduction of the environmental pollution (such as air and noise pollution), traffic problems, and fuel consumption. Hence, development of an urban public transportation system which is responsive to citizen's need and motivates them to use public transportation system is one of the most important objectives and issues that urban planners and designers are concerned about. One solution to achieve this, goal is to develop public transportation system by assistance from the system users. According to approach, users are considered as the valuable resources, because people who are

  6. From networked publics to issue publics

    DEFF Research Database (Denmark)

    Birkbak, Andreas

    2013-01-01

    As an increasing part of everyday life becomes connected with the web in many areas of the globe, the question of how the web mediates political processes becomes still more urgent. Several scholars have started to address this question by thinking about the web in terms of a public space...... that the complex connectivity of the web puts user privacy at risk and enables the enclosure of public debate in virtual echo chambers. Our first argument is that these concerns are united by a set assumptions coming from liberal political philosophy that are rarely made explicit. As a second contribution......, this paper points towards an alternative way to think about publics by proposing a pragmatist reorientation of the public/private distinction in web science, away from seeing two spheres that needs to be kept separate, towards seeing the public and the private as something that is continuously connected...

  7. DescribeX: A Framework for Exploring and Querying XML Web Collections

    CERN Document Server

    Rizzolo, Flavio

    2008-01-01

    This thesis introduces DescribeX, a powerful framework that is capable of describing arbitrarily complex XML summaries of web collections, providing support for more efficient evaluation of XPath workloads. DescribeX permits the declarative description of document structure using all axes and language constructs in XPath, and generalizes many of the XML indexing and summarization approaches in the literature. DescribeX supports the construction of heterogeneous summaries where different document elements sharing a common structure can be declaratively defined and refined by means of path regular expressions on axes, or axis path regular expression (AxPREs). DescribeX can significantly help in the understanding of both the structure of complex, heterogeneous XML collections and the behaviour of XPath queries evaluated on them. Experimental results demonstrate the scalability of DescribeX summary refinements and stabilizations (the key enablers for tailoring summaries) with multi-gigabyte web collections. A com...

    Full Text Available The way in which the social subjects take decisions, the interactions established between these, the web of social institutions and rules, the architecture of the power relationships between the various “points of social coagulation” have as a foundation a complex set of determinants, in which the “pure” economic factors have an important, but not unique role. Thus, this paper intends to draft a possible analytical framework, capable of allowing the stress of some existing connections between the cultural variables, the social actions and the role of the public power. Heavy indebted to OLSON and NOZICK, the starting point is made out by a version of the mandate theory, within the way in which society, as a whole, as well as its individual components, delegates a certain set of social responsibilities to the public authorities, based on some social utility functions, which include the characteristics of the dominant cultural model. Part I of the paper deals with the elements of the theoretical foundation, elements resumed by a set of critical postulates and a special definition of state as the dominant agency in a social space and also of the negotiation/parallel associations. Part II is an attempt to examine some empirical evidences in the favor of some results derived from this foundation. The main conclusion of the paper could be resumed by the idea that trying to describe the interactions between state and society without taking into the account the characteristics of the cultural paradigm is equivalent to talk about Hamlet without mentioning the prince of Denmark.

    Carson, Nancy E; Blake, Christine E; Saunders, Ruth

    2015-04-01

    The aim of this exploratory study was to examine how community-dwelling adults with severe mental illness describe themselves as eaters and how these eating identities relate to dietary intake. Twenty participants completed one in-depth qualitative interview and three 24-h dietary recalls. Two distinct groups were identified; self-described healthy eaters (n = 10) and self-described unhealthy eaters (n = 10). Healthy eaters emphasized fruits and vegetables, limiting sweets, three meals a day, overcoming cost concerns, and benefits of healthy eating. Unhealthy eaters emphasized junk foods, fried foods, few fruits and vegetables, cost and household barriers to healthy eating, and concerns about consequences of unhealthy eating. Self-described healthy eaters consumed significantly more vegetables and less kilocalories, carbohydrates, fat, and saturated fat than self-described unhealthy eaters. Understanding how eating identities relate to dietary intake provides important insights for development of more effective approaches to promote healthy eating in this high risk population.

  3. Predator, Pet Lesbian, or Just The Nanny? LGBTQ Parents of Children With Disabilities Describe Categorization.

    Gibson, Margaret F

    2017-08-11

    How are lesbian/gay/bisexual/trans/queer (LGBTQ) parents of children with disabilities categorized by service providers, and how do parents anticipate, interpret, and respond to such categorizations? This intersectional study investigated the experiences of LGBTQ parents of children with disabilities with service providers in Toronto, Canada. Parents described pressures to "fit" into providers' limited understanding of family. Some parents described facing overt discrimination, including one parent who was seen as a possible sexual predator. Some described being perceived as representatives of "diversity" for organizations, or "pet lesbians" in the words of one couple. Others described being misread as a non-parent, as in "just the nanny," particularly in conjunction with their racial minority status. Parents described how their experiences of being "outside the mainstream" helped them challenge systems and normative beliefs. Findings suggest that a context of scarce disability resources shapes parents' experiences of how LGBTQ identity comes to matter.

    Full Text Available Public Service Motivation concept was developed in North America and focuses on specific motivations of public servants, such as employee satisfaction, organizational commitment, reward preferences, organizational and individual performance. Other types of motivation, as financial consideration, are relevant but have less important influences with regard to this kind of work outcomes. This strengthen the assertion for a diversified motivational strategy, which affect various types of motivation, while not losing sight of the public value that one organization shows and therefore valuing public service motivation as a specific contribution to work outcomes. The concept has been increasingly applied in European public administration. This paper presents Status Quo of international Public Service Motivation research and locates in them empirical evidences from contries that are already working with this concept, like Austria. It also analyses implications for central questions of public management. The main focus of this article is general appropriateness and possible applications for Romanian public management research.

They have developed separately, although they can benefit from insights developed by the other, and this article discusses...... conceptual and empirical relationships between them. Based on a survey of 501 public managers, we find that PSM and PV are associated empirically, but not in a manner allowing total integration. The conceptual discussion reveals how the two concepts cannot be totally separated, as values can be motivating...... and motivation is often oriented toward something desirable (e.g., values). This suggests that neither total separation nor integration is a fruitful strategy. Given that the concepts are related, the literatures may benefit from more awareness of the conceptual overlaps and differences....

  15. The colour of pain: can patients use colour to describe osteoarthritis pain?

    Science.gov (United States)

    Wylde, Vikki; Wells, Victoria; Dixon, Samantha; Gooberman-Hill, Rachael

    2014-03-01

    The aim of the present study was to explore patients' views on the acceptability and feasibility of using colour to describe osteoarthritis (OA) pain, and whether colour could be used to communicate pain to healthcare professionals. Six group interviews were conducted with 17 patients with knee OA. Discussion topics included first impressions about using colour to describe pain, whether participants could associate their pain with colour, how colours related to changes to intensity and different pain qualities, and whether they could envisage using colour to describe pain to healthcare professionals. The group interviews indicated that, although the idea of using colour was generally acceptable, it did not suit all participants as a way of describing their pain. The majority of participants chose red to describe high-intensity pain; the reasons given were because red symbolized inflammation, fire, anger and the stop signal in a traffic light system. Colours used to describe the absence of pain were chosen because of their association with positive emotional feelings, such as purity, calmness and happiness. A range of colours was chosen to represent changes in pain intensity. Aching pain was consistently identified as being associated with colours such as grey or black, whereas sharp pain was described using a wider selection of colours. The majority of participants thought that they would be able to use colour to describe their pain to healthcare professionals, although issues around the interpretability and standardization of colour were raised. For some patients, using colour to describe their pain experience may be a useful tool to improve doctor-patient communication. Copyright © 2013 John Wiley & Sons, Ltd.

  4. Toward accommodating physicians' conscientious objections: an argument for public disclosure.

    Science.gov (United States)

    Harter, Thomas D

    2015-03-01

    This paper aims to demonstrate how public disclosure can be used to balance physicians' conscientious objections with their professional obligations to patients--specifically respect for patient autonomy and informed consent. It is argued here that physicians should be permitted to exercise conscientious objections, but that they have a professional obligation to provide advance notification to patients about those objections. It is further argued here that public disclosure is an appropriate and ethically justifiable limit to the principle of advance notification. The argument for publicly disclosing physicians' conscientious objections is made in this paper by discussing three practical benefits of public disclosure in medicine, and then addressing how publicly disclosing physicians' conscientious objections is not an undue invasion of privacy. Three additional concerns with public disclosure of physicians' conscientious objections are briefly addressed--potential harassment of physicians, workplace discrimination, and mischaracterising physicians' professional aptitude--concluding that each of these concerns requires further deliberation in the realm of business ethics.

    INTRODUCTION: Several models have been used to describe men's and women's sexual responses. These models have been conceptualized as linear or circular models. The circular models were proposed to describe women's sexual function best. AIM: This study aims to determine whether men and women thought...... that current theoretical models of sexual responses accurately reflected their own sexual experience and to what extent this was influenced by sexual dysfunction. METHODS: A cross-sectional study of a large, broadly sampled, nonclinical population, cohort of Danish men and women. The Female Sexual Function...... Index, Female Sexual Distress Scale, and the International Index of Erectile Function were used to describe sexual function. Also, participants completed questionnaires with written descriptions of different sexual responses to describe their most experienced sexual response. MAIN OUTCOME MEASURE...

    An application that queries or consumes descriptions of VO resources must be able to recognize a resource's support for standard IVOA protocols. This specification describes how to describe a service that supports any of the four fundamental data access protocols -- Simple Cone Search (SCS), Simple Image Access (SIA), Simple Spectral Access (SSA), Simple Line Access (SLA) -- using the VOResource XML encoding standard. A key part of this specification is the set of VOResource XML extension schemas that define new metadata that are specific to those protocols. This document describes in particular rules for describing such services within the context of IVOA Registries and data discovery as well as the VO Standard Interface (VOSI) and service self-description. In particular, this document spells out the essential markup needed to identify support for a standard protocol and the base URL required to access the interface that supports that protocol.

  10. Towards a Density Functional Theory Exchange-Correlation Functional able to describe localization/delocalization

    Mattsson, Ann E.; Wills, John M.

    2013-03-01

    The inability to computationally describe the physics governing the properties of actinides and their alloys is the poster child of failure of existing Density Functional Theory exchange-correlation functionals. The intricate competition between localization and delocalization of the electrons, present in these materials, exposes the limitations of functionals only designed to properly describe one or the other situation. We will discuss the manifestation of this competition in real materials and propositions on how to construct a functional able to accurately describe properties of these materials. I addition we will discuss both the importance of using the Dirac equation to describe the relativistic effects in these materials, and the connection to the physics of transition metal oxides.

  20. Comparative urban Bangladesh physics learning experiences as described by students and alumni

    Science.gov (United States)

    Ali, Tanzeem Iqbal

    A neo-culture of extra-curricular coaching prior to sitting the terminal exam was once the privileged domain of public education systems in the Eastern world, but this is no longer the case. This multi-phase study based on a grounded theory approach considered a diversity of physics learning experiences of students and alumni from two urban private schools, an extra-curricular coaching center and a private tutor in a developing South-Asian country. There are various types of tutoring available for students in South Asia as listed by their main characteristics (deCastro and deGuzman, 2012). First 'lean on' is for low achieving slow learners providing hidden remedial activities by school teachers and are usually unregulated. Second, 'pass on' is for students with busy parents, or those lacking assistance with school work. This second type of tutoring provides supplementary activities by school teachers as well as small-scale institutions regulated as a business and an academic entity. Third, 'ride on' is for both high and low achieving students whose parents can afford tutorial fees. This type of tutoring provides structured, remedial and enrichment activities by multinational institutions, experts in the field and university students and are regulated as a business and academic entity. The participants ranged in age from 14 years to 28 years. Phase 1 of the study consisted of a pilot study with online participants who were recent alumni who had taken their formal Physics exit exams quite recently. Clinical interviews and moderated focus group discussions identified nine emerging themes: (i) negative feelings about current education system, (ii) mixed views on coaching outside and beyond school, (iii) negative attitudes about being an O and A level student in urban Bangladesh, (iv) truth about article by (Imam, 2010), (v) negative views on society's influence and local culture about education in Bangladesh, (v) mixed views on extra-curricular activities and physical

  1. Public Computation & Boundary Play

    CERN Document Server

    Sengupta, Pratim

    2016-01-01

    In this paper, we introduce 'public computation' as a genre of learning environments that can be used to radically broaden public participation in authentic, computation-enabled STEM disciplinary practices. Our paradigmatic approach utilizes open source software designed for professional scientists, engineers and digital artists, and situates them in an undiluted form, alongside live and archived expert support, in a public space. We present a case study of DigiPlay, a prototypical public computation space we designed at the University of Calgary, where users can interact directly with scientific simulations as well as the underlying open source code using an array of massive multi- touch screens. We argue that in such a space, public interactions with the code can be thought of as boundary work and play, through which public participation becomes legitimate scientific act, as the public engages in scientific creation through truly open-ended explorations with the code.

    Full Text Available In Portugal we are assisting, since the nineties, to the reform of all public accounting, having as main innovations the utilization of double entry system and the obligatoryness to implement three accounting systems: budget accounting, patrimonial and cost accounting. In the systems of patrimonial and cost accounting, it will be used the accrual systems. The publication of the first Public Accounting Plan (POCP in 1997 identifies the change from a traditional public accounting, which main objective was the execution and budgetary control to a modern public accounting with economical, financial and patrimonial information that serves as basis to the decision making and to the evaluation of public entities concerning the efficient, effective utilization and economy of the public resources, contributing, this way, to the implementation of the New Public Management. The objective of this work has two perspectives: to describe and analyze the situation in Portugal concerning the public accounting reform and to present some results consequent to twelve years of implementation.

    2017-01-01

    Public health policies can elicit strong responses from individuals. These responses can promote, reduce, and even reverse the expected benefits of the policies. Therefore, projections of individual responses to policy can be important ingredients in policy design. Yet our foresight of individual responses to public health investment remains limited. This paper formulates a population game describing the prevention of infectious disease transmission when community health depends on the interactions of individual and public investments. We compare three common relationships between public and individual investments and explain how each relationship alters policy responses and health outcomes. Our methods illustrate how identifying system interactions between nature and society can help us anticipate policy responses.

  9. A pragmatic performance reporting approach for describing PV Hybrid systems within mini-grids. Work in progress from IEA's PVPS Task 11 Act. 31

    Energy Technology Data Exchange (ETDEWEB)

    Swingler, Andrew [Schneider Electric, Burnaby, BC (Canada). Renewable Energies Business

    2010-07-01

    Reviewers of available PV hybrid system and mini-grid case studies are often limited to information detailing the size of the main system components (PV, battery and generator) and perhaps some historical anecdotes recalling major maintenance activities. While this enables rapid insight into the capital cost and perhaps the overall reliability of the system, this information communicates little in the way of system performance from a levelized cost of electricity and GHG emissions point of view - or what can be considered 'the business' perspective. Key system performance information must be available to effectively communicate operational system performance so system operators or perspective customers. Activity 31 of the IEA's PVPS Task 11 looks at how performance reporting can be useful, why it is often absent and what can be done to improve the current situation. This paper reviews some past work in the area of data acquisition and performance calculation used for describing PV Hybrid and mini-grid systems. In particular the IEC 61724 PV performance monitoring standard and results from the 'Benchmarking RE Components and Systems' project are considered. Ultimately, a stripped-down, easier-to-implement and flexible method for monitoring and reporting on key performance indicators is proposed based, in part, on the prior literature. The proposed framework is then used to briefly discuss the performance of two monitored PV hybrid mini-grid examples. (orig.)

  10. Muscle activation described with a differential equation model for large ensembles of locally coupled molecular motors.

    Science.gov (United States)

    Walcott, Sam

    2014-10-01

    Molecular motors, by turning chemical energy into mechanical work, are responsible for active cellular processes. Often groups of these motors work together to perform their biological role. Motors in an ensemble are coupled and exhibit complex emergent behavior. Although large motor ensembles can be modeled with partial differential equations (PDEs) by assuming that molecules function independently of their neighbors, this assumption is violated when motors are coupled locally. It is therefore unclear how to describe the ensemble behavior of the locally coupled motors responsible for biological processes such as calcium-dependent skeletal muscle activation. Here we develop a theory to describe locally coupled motor ensembles and apply the theory to skeletal muscle activation. The central idea is that a muscle filament can be divided into two phases: an active and an inactive phase. Dynamic changes in the relative size of these phases are described by a set of linear ordinary differential equations (ODEs). As the dynamics of the active phase are described by PDEs, muscle activation is governed by a set of coupled ODEs and PDEs, building on previous PDE models. With comparison to Monte Carlo simulations, we demonstrate that the theory captures the behavior of locally coupled ensembles. The theory also plausibly describes and predicts muscle experiments from molecular to whole muscle scales, suggesting that a micro- to macroscale muscle model is within reach.

    Erwin, Paul Campbell; Brownson, Ross C

    2017-08-01

    The requisite capacities and capabilities of the public health practitioner of the future are being driven by multiple forces of change, including public health agency accreditation, climate change, health in all policies, social media and informatics, demographic transitions, globalized travel, and the repercussions of the Affordable Care Act. We describe five critical capacities and capabilities that public health practitioners can build on to successfully prepare for and respond to these forces of change: systems thinking and systems methods, communication capacities, an entrepreneurial orientation, transformational ethics, and policy analysis and response. Equipping the public health practitioner with the requisite capabilities and capacities will require new content and methods for those in public health academia, as well as a recommitment to lifelong learning on the part of the practitioner, within an increasingly uncertain and polarized political environment.

    Full Text Available The purpose of this essay is to characterize the perspectives of modern and postmodern public administration.Modernist approaches have crossed the discipline from its origins to the present day, focusing on the substantive and instrumental reason. The weberian bureaucracy and systems theory are the main paradigms of modern public organization.Postmodernism confronts with the modern look. There is not a postmodernist theory; however there are authors who are described as postmodernists. They postulate the end of the great myths, life as a virtual reality, media, spoken and interpreted. They question the illusionary falsehood of modernity and the reason as a founding relationship and explanatory of public administration. Critical, interpretative, deconstructive, constructive theories of the, device and the rhizomatic ones, are among the so-called postmodern.Both perspectives provide us with views for a better understanding of the public administration.Key words: Modernity, postmodernity, public administration.

  15. [Public policy analysis].

    Subirats, J

    2001-01-01

    This article presents to public health professionals concepts and perspectives from political science relevant for creating a healthier public policy. Currently, there is no uniform vision of what constitutes public interest and the decisions of public administrations tend to be based on compromise. In public debate, what is paramount is the capacity to persuade. From the perspective of public policy analysis, the crucial issue is definition: the final decision depends on the definition of the problem that has emerged triumphant in the public debate among competing actors with different definitions of the problem. From a policy analysis perspective, the problems entering the agenda of public administration does not necessarily correspond to their severity, as competing actors try to impose their point of view. Because of its historical evolution, the Spanish political system has specific traits. The relatively weak democratic tradition tends to make the decision process less visibles, with strong technocratic elements and weaker social articulation. Both the juridical tradition and liberal rhetoric portray lobbying as contrary to public interest, when in fact it is constantly performed by powerful vested interest groups, through both personal contacts and economic connections. Regulatory policies, with concentrated costs and diffuse benefits, seem to be moving from Spain to the European Union. To promote healthier public policies, the development of civil society initiatives and the building of coalitions will play an increasingly greater role in the future.

  16. Imaging system of wavelet optics described by the Gaussian linear frequency-modulated complex wavelet

    Science.gov (United States)

    Tan, Liying; Ma, Jing; Wang, Guangming

    2005-12-01

    The image formation and the point-spread function of an optical system are analyzed by use of the wavelet basis function. The image described by a wavelet is no longer an indivisible whole image. It is, rather, a complex image consisting of many wavelet subimages, which come from the changes of different parameters (scale) a and c, and parameters b and d show the positions of wavelet subimages under different scales. A Gaussian frequency-modulated complex-valued wavelet function is introduced to express the point-spread function of an optical system and used to describe the image formation. The analysis, in allusion to the situation of illumination with a monochromatic plain light wave, shows that using the theory of wavelet optics to describe the image formation of an optical system is feasible.

  17. A Meta-model Describing the Development Process of Mobile Learning

    Science.gov (United States)

    Wingkvist, Anna; Ericsson, Morgan

    This paper presents a meta-model to describe the development process of mobile learning initiatives. These initiatives are often small scale trials that are not integrated in the intended setting, but carried out outside of the setting. This results in sustainability issues, i.e., problems to integrate the results of the initiative as learning aids. In order to address the sustainability issues, and in turn help to understand the scaling process, a meta-model is introduced. This meta-model divides the development into four areas of concern, and the life cycle of any mobile learning initiative into four stages. The meta-model was developed by analyzing and describing how a podcasting initiative was developed, and is currently being evaluated as a tool to both describe and evaluate mobile learning initiatives. The meta-model was developed based on a mobile learning initiative, but the meta-model itself is extendible to other forms of technology-enhanced learning.

  18. Navier-Stokes equation describes the movement of a special superfluid medium

    CERN Document Server

    Sbitnev, Valeriy I

    2015-01-01

    The Navier-Stokes equation contains two terms which have been subjected to slight modification: (a) the viscosity term depends of time (the viscosity in average on time is zero, but its variance is nonzero); (b) the pressure gradient contains an added term describing the entropy gradient multiplied by the pressure. Owing to these modifications, the Navier-Stokes equation can be reduced to the Schr\\"odinger equation describing behavior of a particle into the vacuum, where the vacuum is a superfluid medium. Vortex structures arising in this medium show infinitely long life owing to zero average viscosity. The nonzero variance describes exchange of the vortex energy with zero-point energy of the vacuum. Radius of the vortex trembles around some average value. This observation sheds the light to the Zitterbewegung phenomenon. The vortex has a non-zero core where the vortex velocity vanishes. Its organization is discussed with the point of view of the Calabi-Yau manifold.

    The genus Aeromonas comprises primarily aquatic bacteria and also serious human and animal pathogens with the occurrence in clinical material, drinking water, and food. Aeromonads are typical for their complex taxonomy and nomenclature and for limited possibilities of identification to the species level. According to studies describing the use of MALDI-TOF MS in diagnostics of aeromonads, this modern chemotaxonomical approach reveals quite high percentage of correctly identified isolates. We analyzed 64 Aeromonas reference strains from the set of 27 species. After extending the range of analyzed Aeromonas species by newly described ones, we proved that MALDI-TOF MS procedure accompanied by Biotyper tool is not a reliable diagnostic technique for aeromonads. We obtained quite high percentage of false-positive, incorrect, and uncertain results. The identification of newly described species is accompanied with misidentifications that were observed also in the case of pathogenic aeromonads.

    Full Text Available Abstract Background Experience with public engagement activities regarding the risks and benefits of science and technology (S&T is growing, especially in the industrialized world. However, public engagement in the developing world regarding S&T risks and benefits to explore health issues has not been widely explored. Methods This paper gives an overview about public engagement and related concepts, with a particular focus on challenges and benefits in the developing world. We then describe an Internet-based platform, which seeks to both inform and engage youth and the broader public on global water issues and their health impacts. Finally, we outline a possible course for future action to scale up this and similar online public engagement platforms. Results The benefits of public engagement include creating an informed citizenry, generating new ideas from the public, increasing the chances of research being adopted, increasing public trust, and answering ethical research questions. Public engagement also fosters global communication, enables shared experiences and methodology, standardizes strategy, and generates global viewpoints. This is especially pertinent to the developing world, as it encourages previously marginalized populations to participate on a global stage. One of the core issues at stake in public engagement is global governance of science and technology. Also, beyond benefiting society at large, public engagement in science offers benefits to the scientific enterprise itself. Conclusion Successful public engagement with developing world stakeholders will be a critical part of implementing new services and technologies. Interactive engagement platforms, such as the Internet, have the potential to unite people globally around relevant health issues.

  1. A method for describing the canopy architecture of coppice poplar with allometric relationships.

    Casella, Eric; Sinoquet, Hervé

    2003-12-01

    A multi-scale biometric methodology for describing the architecture of fast-growing short-rotation woody crops is used to describe 2-year-old poplar clones during the second rotation. To allow for expressions of genetic variability observed within this species (i.e., growth potential, leaf morphology, coppice and canopy structure), the method has been applied to two clones: Ghoy (Gho) (Populus deltoides Bartr. ex Marsh. x Populus nigra L.) and Trichobel (Tri) (Populus trichocarpa Torr. & A. Gray x Populus trichocarpa). The method operates at the stool level and describes the plant as a collection of components (shoots and branches) described as a collection of metameric elements, themselves defined as a collection of elementary units (internode, petiole, leaf blade). Branching and connection between the plant units (i.e., plant topology) and their spatial location, orientation, size and shape (i.e., plant geometry) describe the plant architecture. The methodology has been used to describe the plant architecture of 15 selected stools per clone over a 5-month period. On individual stools, shoots have been selected from three classes (small, medium and large) spanning the diameter distribution range. Using a multi-scale approach, empirical allometric relationships were used to parameterize elementary units of the plant, topological relationships and geometry (e.g., distribution of shoot diameters on stool, shoot attributes from shoot diameter). The empirical functions form the basis of the 3-D Coppice Poplar Canopy Architecture model (3-D CPCA), which recreates the architecture and canopy structure of fast-growing coppice crops at the plot scale. Model outputs are assessed through visual and quantitative comparisons between actual photographs of the coppice canopy and simulated images. Overall, results indicate a good predictive ability of the 3-D CPCA model.

The problem of determining the stability margin of those systems with linear affine dependence of the coefficients of a characteristic polynomial on system parameters is studied. Fuzzy numbers describing the system parameters are allowed to be characterized by arbitrary nonsymmetric membership functions. An elegant solution, graphical in nature, based on generalization of the Tsypkin-Polyak plot is presented. The advantage of the presented approach over the classical robust concept is demonstrated on a control of the Fiat Dedra engine model and a control of the quarter car suspension model.

    The purpose of our current study is to describe the guidelines regarding trephination as suggested in the Hippocratic writer's book, "Peri ton en cephali traumaton" ("On Head Wounds"). The ancient Greek text was reviewed as well as two English translations. The Hippocratic author described the indications, timing, and techniques of trephination for patients with head injury. He emphasized that attention should be paid to the details of the employed technique. He also commented on the difference of skull thickness at different anatomical sites and also between different age groups. The Hippocratic recommendations provided details for the performance of trephination by the ancient Greek physicians that are still considered important in modern neurosurgery.

    modeling to predict soil properties. However, information derived from spectra can also be used to describe the soil and how it varies across landscapes. The reason is that spectra contain information on the fundamental composition of soil: its organic matter, and iron oxide, clay and carbonate minerals...... the PCA were clustered using k-means to help with interpretation. Soil properties of the clusters were described using the mean spectrum of each class. We mapped the scores of the first three principal components using ordinary kriging. These maps and a cluster map derived with k-means clustering were...

    Full Text Available A model to describe the constitutive behavior of magnetic shape memory alloy composed with pure martensite is proposed based on the analysis of variants reorientation. A hyperbolic tangent expression is given to describe the variants transition during magnetic and mechanical loading process. The main features of magnetic shape memory alloy, such as pseudoelastic and partially pseudoelastic behavior as well as minor hysteretic loops, can be successfully replicated with the proposed model. A good agreement is achieved between calculated results and experimental data for NiMnGa single crystal.

    Nematodes of the genus Anisakis have marine fishes as intermediate hosts. One of these hosts is Thyrsites atun, an important fishery resource in Chile between 38 and 41° S. This paper describes the frequency and number of Anisakis nematodes in the internal organs of Thyrsites atun. An analysis based on spatial distribution models showed that the parasites tend to be clustered. The variation in the number of parasites per host could be described by the negative binomial distribution. The maximum observed number of parasites was nine parasites per host. The environmental and zoonotic aspects of the study are also discussed.

    Full Text Available The issue of public budgeting is an important issue for public policy of the state, for the simple reason that no money from the state budget can not promote public policy. Budgetary policy is official government Doctrine vision mirror and also represents a starting point for other public policies, which in turn are financed by the public budget. Fiscal policy instruments at its disposal handles the public sector in its structure, and the private sector. Tools such as grant, budgetary allocation, tax, welfare under various forms, direct investments and not least the state aid is used by the state through their budgetary policies to directly and indirectly infuence sector, and the private. Fiscal policies can be grouped according to the structure of the public sector in these components, namely fiscal policy, budgeting and resource allocation policies for financing the budget deficit. An important issue is the financing of the budget deficit budgetary policies. There are two funding possibilities, namely, the higher taxes or more axles site and enter the second call to public loans. Both options involve extra effort from taxpayers in the current fiscal year when they pay higher taxes or a future period when public loans will be repaid. We know that by virtue of "fiscal pact" structural deficits of the member countries of the EU are limited by the European Commission, according to the macro structural stability and budget of each Member State. This problem tempers to some extent the governments of the Member States budgetary appetite, but does not solve the problem of chronic budget deficits. Another issue addressed in this paper is related to the public debt, the absolute amount of its relative level of public datoriri, about the size of GDP, public debt financing and its repayment sources. Sources of public debt issuance and monetary impact on the budget and monetary stability are variables that must underpin the justification of budgetary

    A preliminary provisional assessment of the prospects for the establishment of an adequate technology assessment function and the implications of the assessment function for the public decision process are presented. Effects of the technology assessment function on each phase of the public decision process and briefly explored. Significant implications during the next decade are projected with respect to the following phases: invention and development of alternative means (technological configurations); evaluation, selection and promotion of preferred courses of action; and modification of statutory scheme or social action program as an outcome of continuing monitoring and appraisal.

    Full Text Available The emergence of public finances is due to objective causes needs and determined their main function being to obtain the financial resources it needs for the State to exercise its powers and on the way to intervene in the economy and society general. Public finances are necessary, subjectively and objectively, as it contributes to accomplishing the tasks and functions of the state, which could not be realized without financial leverage. Public finances are inextricably linked to the existence of the state, and public sector's role in the economy. Thus, they express "social relations, economic arising in the establishment and use of public funds between the state, on the one hand, and members of society on the other hand, to meet the needs of general interest of society" [1]. Thus, the role of public finance is to meet the needs of general interest or collective needs.

    Full Text Available The state administration process and hence also the economy coordination effort requires the promotion of robust, consistent and transparent public policy, which must be accepted by all stakeholders of economic development. Public policy is a set of measures taken by the authorities legally constituted as public power. Under normal conditions these policy aims at improving living conditions of citizens by developing grounded strategies which are applied by measures implemented to stimulate economic development in all its complexity by harmonizing the efforts of the institutional and non-institutional bodies responsible for ensuring the overall public interest. In Romania, public policies, especially fiscal ones on which we dwell, not reached in many cases the expected effects primarily because of their superficial grounding, lack of transparency, unpredictability, poor communication and secondly as an effect of ineffective management of public financial resources.

  15. Food, publics, science.

    Blue, Gwendolyn

    This paper draws attention to food as a site around which a historically particular form of public engagement has emerged. In the past decade, some of the most lively debates and policy actions for science and publics have focused on food related issues: first with BSE and subsequently with genetically modified organisms. Even though much of the literature surrounding publics and science acknowledges that the very definition of "publics" is shifting, little attention has been paid to food as a significant arena in which publics are engaging in politically motivated challenges to techno-scientific practices, policies and institutions. Taking food seriously means contextualizing publics as well as extending discursive models of democratic engagement to embrace consumer practices.

  17. Which Metrics Are Appropriate to Describe the Value of New Cancer Therapies?

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Patients with certain cancers are treated with curative intent, but for others the results are less favorable and different therapeutic approaches are needed. Early data suggest that new therapies, which modulate immune responses to cancers, may have potential for long-term survival in a proportion of cases. Therefore, it is timely to consider whether metrics generally used to describe the medical value of therapies for patients with common solid tumors remain appropriate for therapies with curative potential. Literature reviews were conducted to define how various stakeholders describe cure in oncology and to identify the endpoints used in clinical trials for selected solid tumors. The results showed that “cure” is described using various terms that can be divided broadly into lack of disease progression, eradication of cancerous cells, and survival. The review of trial endpoints showed frequent use of median overall survival (OS and progression- and response-related endpoints. Because these endpoints were mainly described in the context of chemotherapies that are not generally curative, they may not adequately capture outcomes of new therapeutic modalities with potential for long-term survival. More appropriate endpoints may include mean OS, cure fraction, and OS rate at landmark time points.
