    The original taxonomy of educational objectives, developed by Benjamin S.␣Bloom and his associates in the 1950s, was revised several decades later by a group of educationists and cognitive psychologists, who developed a revised taxonomy (RT). This article describes a Turkish study carried out among a group of pre-service teachers in order to compare the influence of the two systems on lesson planning skills. The results confirmed other studies that have indicated a number of advantages of the revised system over the earlier one.

    Science.gov (United States)

    2017-06-01

    The "Benjamin Button" effect inspired by the popular motion picture, is used to describe the goal of achieving a clearly younger and more attractive, yet still natural appearance utilizing noninvasive and minimally invasive therapies and procedures. Due to high patient demand for enhancement and rejuvenation of the face and body with minimal downtime, there is an ever-increasing number of companies developing products and devices, variety of indications, and field of practitioners offering them. Each option, including topicals, injectables, and devices, promises near magical results. Despite that, a brief review of online discussions and media resources reveals both patients complaining of inadequate results and celebrities with extreme appearances. For clinical practitioners, it is critical to understand the art, science, and economics of noninvasive rejuvenation in order to properly evaluate potential patients, set appropriate expectations, develop, and provide an effective noninvasive rejuvenation plan to achieve a true "Benjamin Button" effect for patients.

  17. Benjamin and Koolhaas: History's Afterlife

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Dialectical images are at the core of the methods suggested by two books written four decades apart yet published around the same time. The Arcades Project (first published as Das Passagen-Werk in 1981 and Delirious New York (1978 use images to critique established modes of historical interpretation. Each proposes a methodology of historical speculation based on the interpretation of fragmentary visual phenomena. Both construct alternative historical narratives about the impact of technology, mass culture and economy on the city. This essay contrasts and compares the similarities and differences between the respective authors’ treatments of the nineteenth century arcade and the Manhattan skyscraper to examine how the strategies and definitions suggested by Benjamin and Koolhaas address the function of images as tools for critical architectural analysis and knowledge.

Sometimes people realise that something is wrong, but they can’t say why. In such cases, I may be able to use a discussion to assess the nature of the problem and determine if further sessions are needed. If that is the case, I can either conduct the session...

In the "idealism" of the philosophy that comes from Jonia and reaches Jena, Rosenzweig animadverted on the tendency to a totalitarianism that potentially converted it into an "ontology of war". Benjamin brought to light the radical ambiguity within the concept of progress, so fundamental to the illustrated thought. Barbarism, in general, and fascism, in particular, are not the opposite to progress but one of its possibilities. That fatal possibility is, for the victim, the rule. Kafka traced with foresight the fascist reduction of man to bare life in the recurrent animalisation of his characters, as well as the denial of the other in those presented as victims of incommunications.

    Hubo pensadores que supieron leer en su tiempo signos de la catástrofe venidera. No eran profetas sino finos analistas. Nos referimos a Rosenzweig, Benjamin y Kafka. Rosenzweig denunció en el "idealismo" de la filosofía que viene desde Jonia y llega hasta Jena la tendencia a un totalitarismo que la convertía en potencialmente en una "ontología de la guerra". Benjamin dejó constancia de la ambigüedad radical del concepto de progreso, tan fundamental para el pensamiento ilustrado. La barbarie, en general, y el fascismo, en particular, no son lo opuesto al progreso sino una de sus posibilidades. Esa fatal posibilidad es, para la víctima, la norma. Kafka capta anticipadamente la reducción fascista del hombre a nuda vida en la recurrente animalización de sus personajes, así como la negación del otro en sus personajes víctimas de la incomunicación.

    David Kishik

    2013-11-01

    Full Text Available What if Walter Benjamin actually made it to New York as he was escaping the Nazis, settling there for the rest of his long life? What if he was working on a sequel to his Arcades Project, translating his ideas about Paris, capital of the nineteenth century, to his new city and own epoch? And what if I inadvertently discovered the manuscript of this so-called Manhattan Project, and decided to write a study dedicated to the unearthed text? This paper offers a few reflections on, and quotations from, the book that I am currently, truly working on, which is an analysis of a phantom of a book, inspired by a real collection of reflections and quotations that were made in preparation for another book that was also never written.

  16. Benjamin Constant. Libertad, democracia y pluralismo

    Directory of Open Access Journals (Sweden)

    Claudia Patricia Fonnegra Osorio

    2015-12-01

    Full Text Available A partir de un enfoque interpretativo, en este artículo se aborda por qué para Benjamin Constant la democracia solo puede darse en donde se presenta una relación necesaria entre la libertad entendida como defensa de los derechos individuales -libertad como independencia o negativa- y la libertad concebida como principio de la participación pública -libertad como autonomía o positiva-. Asimismo, se presenta la importancia que atribuye el autor a las tradiciones que dan vida a la configuración del universo cultural de un pueblo. Se concluye que en la obra de Constant se encuentra una clara defensa del Estado de derecho y del pluralismo, la cual puede iluminar la comprensión de los problemas políticos de la contemporaneidad.

  17. Walter Benjamin's allegory and the modernity

    Directory of Open Access Journals (Sweden)

    João Batista Pereira

    2013-12-01

    Full Text Available Committed since Classical Antiquity with the rhetoric and the rules of oratory, the allegory was like a displaced metaphor, striving for clarity of speech. That purpose was transfigured throughout the Middle Ages, when its use was linked to decency and morality, a convention which was changed in Romanticism, when it met its demise. From the texts proposed by Walter Benjamin, its existence was perceived as a resource illuminating the aesthetic universe in the social times, a figure of speech tied to the historical context. We adopt in this article a dialectical perspective as a methodological that more accurately illustrates the contours assumed by allegory in modernity. With the light of experiences in a changing world of insecurity in its own values, it is now envisioned as a category indicting of fragmented representation of society, allowing us to understand the limits of literature as a vehicle in critical of reality.

  18. George Kelly: cognitive psychologist, humanistic psychologist, or something else entirely?

    Science.gov (United States)

    Benjafield, John G

    2008-11-01

    George Kelly was regarded by some of his contemporaries as a cognitive psychologist and by others as a humanistic psychologist. Kelly himself resisted being rubricized. He did, however, name several people who had been influential in his life and work, one of whom was J.F. Herbart. A comparison of Herbart and Kelly reveals several similarities. Both shared a belief that psychology was fundamentally a mathematical discipline. Both eliminated distinctions usually taken for granted in psychology, such as emotion versus cognition. Reconstructing Kelly's relation to Herbart allows one to see more clearly why Kelly was such a unique figure in 20th century psychology.

  1. Recognition of names of eminent psychologists.

    Science.gov (United States)

    Duncan, C P

    1976-10-01

    Faculty members, graduate students, undergraduate majors, and introductory psychology students checked those names they recognized in the list of 228 deceased psychologists, rated for eminence, provided by Annin, Boring, and Watson. Mean percentage recognition was less than 50% for the 128 American psychologists, and less than 25% for the 100 foreign psychologists, by the faculty subjects. The other three groups of subjects gave even lower recognition scores. Recognition was probably also influenced by recency; median year of death of the American psychologists was 1955, of the foreign psychologists, 1943. High recognition (defined as recognition by 80% or more of the faculty group) was achieved by only 34 psychologists, almost all of them American. These highly recognized psychologists also had high eminence ratings, but there was an equal number of psychologists with high eminence ratings that were poorly recognized.

  2. Harmful Algal Blooms

    Science.gov (United States)

    Graham, Jennifer L.

    2007-01-01

    What are Harmful Algal Blooms (HABs)? Freshwater and marine harmful algal blooms (HABs) can occur anytime water use is impaired due to excessive accumulations of algae. HAB occurrence is affected by a complex set of physical, chemical, biological, hydrological, and meteorological conditions making it difficult to isolate specific causative environmental factors. Potential impairments include reduction in water quality, accumulation of malodorous scums in beach areas, algal production of toxins potent enough to poison both aquatic and terrestrial organisms, and algal production of taste-and-odor compounds that cause unpalatable drinking water and fish. HABs are a global problem, and toxic freshwater and (or) marine algae have been implicated in human and animal illness and death in over 45 countries worldwide and in at least 27 U.S. States (Yoo and others, 1995; Chorus and Bartram, 1999; Huisman and others, 2005).

    1994-03-01

    A partial report from a study dealing with Psychology's current status in Argentina is presented. Pursuant to this preliminary study 36,128 psychologists have taken their degree at both State and private universities in Argentina--between 1956, when the first Department of Psychology was created, and 1992. So, over a 32.5-million population (as per the 1991 census), there is a psychologist every 897 inhabitants, or 111 psychologists every 100,000 inhabitants. According to psychologists' geographical distribution, the highest density is to be found in the capital city of Buenos Aires (one psychologist every 246 inhabitants) while the lowest density is to be found in the Province of Chaco (one psychologist every 17,465 inhabitants). During year 1993, a total of 26,726 students have been studying Psychology at the different Argentine universities: Of these, 6,858 have taken their Psychology degree during this academic year. A great majority of psychologists work in the clinical field, being Psychoanalysis their prominent theoretical orientation. Ladies psychologists supposedly account for 85% of the overall number of psychologists. Psychological Associations have 24,878 active psychologists recorded, of which a great majority work in the clinical field.

  8. An art history of means: Arendt-Benjamin

    Directory of Open Access Journals (Sweden)

    Jae Emerling

    2009-12-01

    Full Text Available Transmissibility is an essential concept for any discourse on historiography and aesthetics. In fact, this concept traverses the contemporary impasse of art historical critical practice. Although explicitly associated with Walter Benjamin, the entirety of Hannah Arendt’s work on art and history is premised on transmissibility as well. It allows them to conceive a space of history from within the aesthetic, the world of artifice. This essay reads Benjamin and Arendt alongside and against one other in order to rethink art and history without resorting to eschatology or the histrionics of political theology. In creating this virtual historiography—Arendt-Benjamin—it conceives transmissibility as an aesthetic-historiographic concept that renders an openness between past and future, poiesis and aisthesis. Writing the history of art becomes the creation of a passage between what-has-been and artifice; it becomes the opening of history into life, an event of recollection.

  12. Benjamin's conception of language and Adorno's aesthetic theory

    Directory of Open Access Journals (Sweden)

    Rodrigo Duarte

    Full Text Available According to the theory of language of the young Benjamin, the primary task of language isn't the communication of contents, but to express itself as a "spiritual essence" in which also men take part. That conception according to which language would be a medium to signification of something outside it leads to a necessary decrease of its original strength and is thus denominated by Benjamin bürgerlich. The names of human language are remainders of an archaic state, in which things weren't yet mute and had their own language. Benjamin suggests also that all the arts remind the original language of things, as they make objects "speak" in form of sounds, colors, shapes etc. That relationship between arts as reminders of the "language of things" and the possible reconciliation of mankind with itself and with nature has been developed by Theodor Adorno in several of his writings, specially in the Aesthetic Theory, where the artwork is ultimately conceived as a construct pervaded by "language" in the widest meaning - not in the "bourgeois" sense.

This fictional incident is the basis of James Joyce’s Ulysses, the greatest novel of modern times. It has also given rise to Bloomsday, a kind of Irish literary holy day celebrated in cities all around the world. It was a specially appropriate moment for us to celebrate the birth of our new peak body, because Bloomsday provides a perfect parable for why the Australian public and government should cherish our sector.

    Full Text Available Este artigo é uma leitura do texto de Walter Benjamin Paris capital do século XIX. A partir do conjunto de anotações que Benjamin faz de diversos livros consultados, principalmente durante sua pesquisa na Bibliothèque Nationale, o autor pretende trabalhar a noção de indivíduo vinculando-a a dois temas. Primeiro, a emergência do flâneur como tradução do espírito de mobilidade que se inaugura com a modernidade. Para isso a discussão sobre a noção de espaço, particularmente no que diz respeito a cidade de Paris, é importante. O flâneur surge assim como um indivíduo desenraizado que se locomove através do espaço urbano remodelado. Segundo, uma aproximação entre o ato da flânerie e o trabalho intelectual. Considerando a flânerie como uma atividade intelectual o autor mostra como os temas do distanciamento e da construção do objeto são relevantes tanto para o flâneur-detetive quanto para a reflexão nas ciências sociais.This paper is an interpretation of Walter Benjamins Paris, Capital of the 19th Century. Based on the notes Benjamin made on several books he read, mainly during his research at the Bibliotèque Nationale, the author discusses the notion of the individual linking it to two themes. First, to the emergence of the flâneur as a translation of the spirit of mobility which starts with modernity. The discussion on the notion of space, especially where it concerns Paris, is essential for this analysis. The flâneur is seen as an uprooted individual who moves around the remodelled urban space. Second, to the proximity between the act of flânerie and that of intellectual work. Taking flânerie to be intellectual activity, the author shows how the themes of the distancing and the construction of the object are relevant, both to the detective-flâneur and to the reflection in social sciences.

These concepts are not elaborated in way explicit or systematic by both, to the opposite they are related subtlety the some aspects of the contemporary social life, as the disappearance of the experience, the decline of the narration, the loss of the sense of the history and the consequent suppression of the memory, the appearance of the cultural industry. Of that it sorts things out, explicit those concepts, especially when referred the those subjects, it helps us not only to understand the conception of Benjamin and Adorno, but also your judgements on the cultural scene of the beginning of the century - without, though, to intend to establish a model of what can be the resistance or the conformism. Keywords: Resistance. Conformism. Culture. Romances. School of Frankfurt. Este trabalho pretende, com base em alguns textos de Theodor Adorno e de Walter Benjamin, discutir o significado dos conceitos de “resistência” e de “conformismo” para tais autores. Esses conceitos não são elaborados de modo explícito ou sistemático por ambos; ao contrário, são sutilmente relacionados a alguns aspectos da vida social contemporânea, como o desaparecimento da experiência, o declínio da narração, a perda do sentido da história e a conseqüente supressão da memória, e o surgimento da indústria cultural. Dessa maneira, explicitar esses conceitos, especialmente quando referidos a essas questões, ajuda-nos não só a entender a concepção de Benjamin e de Adorno, mas também seus juízos sobre a cena cultural do início do século XX - sem, todavia, pretender estabelecer um modelo do que possa ser a resistência ou o conformismo.

  13. Time-periodic solutions of the Benjamin-Ono equation

    Ambrose , D.M.; Wilkening, Jon

    2008-04-01

    We present a spectrally accurate numerical method for finding non-trivial time-periodic solutions of non-linear partial differential equations. The method is based on minimizing a functional (of the initial condition and the period) that is positive unless the solution is periodic, in which case it is zero. We solve an adjoint PDE to compute the gradient of this functional with respect to the initial condition. We include additional terms in the functional to specify the free parameters, which, in the case of the Benjamin-Ono equation, are the mean, a spatial phase, a temporal phase and the real part of one of the Fourier modes at t = 0. We use our method to study global paths of non-trivial time-periodic solutions connecting stationary and traveling waves of the Benjamin-Ono equation. As a starting guess for each path, we compute periodic solutions of the linearized problem by solving an infinite dimensional eigenvalue problem in closed form. We then use our numerical method to continue these solutions beyond the realm of linear theory until another traveling wave is reached (or until the solution blows up). By experimentation with data fitting, we identify the analytical form of the solutions on the path connecting the one-hump stationary solution to the two-hump traveling wave. We then derive exact formulas for these solutions by explicitly solving the system of ODE's governing the evolution of solitons using the ansatz suggested by the numerical simulations.

    This chapter explores the place of Scottish medicine in the autobiographical writing of the Philadelphia physician and signer of the American Declaration of Independence, Benjamin Rush, who studied at the University of Edinburgh from 1766 to 1768. It focuses on Rush's 'Scottish journal' (his account of his period of study in Edinburgh), his protracted feud from 1797 over his treatment of yellow fever with the English journalist, politician and agriculturalist William Cobbett, and his account in 'Travels through Life' of that feud and of the influence of Cullen on his medical theory and practice. The different rhetorical strategies used by Rush to defend his character and practice and his role in the rise of physician autobiography are examined.

  1. Without Pictorial Detour: Benjamin, Mies and the Architectural Image

    Directory of Open Access Journals (Sweden)

    Lutz Robbers

    2016-05-01

    Full Text Available It can be argued that architectural knowledge was of crucial importance to Walter Benjamin for elaborating his version of an anthropological historical materialism. Between 1929 and 1931 he encounters two publications on architectural history which had a decisive impact on his ensuing works: Sigfried Giedion’s Bauen in Frankreich, Bauen in Eisen, Bauen in Eisenbeton (1928 and Carl Linfert’s Die Grundlagen der Architekturzeichnung (1931. It can be argued that both works played a role in affirming, if not developing his historical method of awakening the dreaming collective into a ‘now of recognisability,’ a method which one can argue is based on a specific image-based epistemology. Especially the architectural image, whether in the form of a printed drawing, photographic illustration, or an actual built object, appears to have been crucial for placing the history of media technologies (architecture being one of these media in a constellation with the ‘archaic symbol-worlds of mythologies.’ If architecture is, as Benjamin claims in his initial notes for The Arcades Project, ‘the most important testimony to latent “mythology,”’ the architectural image might very well be the agent that causes the moment of awakening, the instance when a constellation between technology and ancient symbol worlds is formed. In the second part of this essay, I will attempt to elaborate such a designation for the specificity of the architectural image by analysing a number of Ludwig Mies van der Rohe’s drawings and collages from the 1920s as architectural images in the Benjaminian sense.

  2. Messianica ratio. Affinities and Differences in Cohen’s and Benjamin's Messianic Rationalism

    Directory of Open Access Journals (Sweden)

    Fabrizio Desideri

    2015-11-01

    Full Text Available In my paper, I intend firmly to criticize Taubes' interpretation of Benjamin's Theology as a modern form of Gnosticism (Benjamin as a modern Marcionit. In a positive way, I sustain rather the thesis that Benjamin's Messianism is in close connection with his conception of reason (“the sharpened axe of reason” and, in particularly, with the paradoxical unity of Mysticism and Enlightenment, which, according to the famous definition of Adorno, distinguishes his thought. As a radically anti-magical and anti-mythical conception of the historical time, Benjamin's Messianism has to be considered as an original synthesis between motifs of the mystical tradition of the Jewish Kabbalah and motifs belonging to the rationalist tradition of the Jewish philosophy. Moving from Cohen's standpoint of a continuity between Maimonides and Kant, I consider therefore the affinity between his messianic conception of history and that of Benjamin. Both, Benjamin and Cohen, share, together with the reference to the a priori of the idea of justice, the reference to the Kantian connection between rationality and hope. Hence originates the non-eschatological Messianism of both. Motives of difference between Cohen and Benjamin’s messianic idea are to be found, conversely, in their different way to consider the idea of "the infinite task" and of its infinite fulfillment in the context of the historical time. Unlike the fundamentally ethical interpretation that Cohen gives of this relationship, Benjamin understands it ontologically in a monadological sense. This explains the constitutive relationship that exists, in Benjamin's philosophy, between Origin, Fragment and Revelation. In the light of this connection, Benjamin's messianic understanding of the historical time exceeds the Scholemian alternative between a restorative and a utopian conception of Messianism.

  12. Integrable hydrodynamics of Calogero-Sutherland model: bidirectional Benjamin-Ono equation

    2009-01-01

    We develop a hydrodynamic description of the classical Calogero-Sutherland liquid: a Calogero-Sutherland model with an infinite number of particles and a non-vanishing density of particles. The hydrodynamic equations, being written for the density and velocity fields of the liquid, are shown to be a bidirectional analog of the Benjamin-Ono equation. The latter is known to describe internal waves of deep stratified fluids. We show that the bidirectional Benjamin-Ono equation appears as a real reduction of the modified KP hierarchy. We derive the chiral nonlinear equation which appears as a chiral reduction of the bidirectional equation. The conventional Benjamin-Ono equation is a degeneration of the chiral nonlinear equation at large density. We construct multi-phase solutions of the bidirectional Benjamin-Ono equations and of the chiral nonlinear equations

  13. Dinoflagellate blooms in upwelling systems: Seeding, variability, and contrasts with diatom bloom behaviour

    Science.gov (United States)

    Smayda, T. J.; Trainer, V. L.

    2010-04-01

    The influence of diatom bloom behaviour, dinoflagellate life cycles, propagule type and upwelling bloom cycles on the seeding of dinoflagellate blooms in eastern boundary current upwelling systems is evaluated. Winter-spring diatom bloom behaviour is contrasted with upwelling bloom behaviour because their phenology impacts dinoflagellate blooms. The winter-spring diatom bloom is usually sustained, whereas the classical upwelling diatom bloom occurs as a series of separate, recurrent mini-blooms intercalated by upwelling-relaxation periods, during which dinoflagellates often bloom. Four sequential wind-regulated phases characterize upwelling cycles, with each phase having different effects on diatom and dinoflagellate bloom behaviour: bloom “spin up”, bloom maximum, bloom “spin down”, and upwelling relaxation. The spin up - bloom maximum is the period of heightened diatom growth; the spin down - upwelling-relaxation phases are the periods when dinoflagellates often bloom. The duration, intensity and ratio of the upwelling and relaxation periods making up upwelling cycles determine the potential for dinoflagellate blooms to develop within a given upwelling cycle and prior to the subsequent “spin up” of upwelling that favours diatom blooms. Upwelling diatoms and meroplanktonic dinoflagellates have three types of propagules available to seed blooms: vegetative cells, resting cells and resting cysts. However, most upwelling dinoflagellates are holoplanktonic, which indicates that the capacity to form resting cysts is not an absolute requirement for growth and survival in upwelling systems. The long-term (decadal) gaps in bloom behaviour of Gymnodinium catenatum and Lingulodinium polyedrum, and the unpredictable bloom behaviour of dinoflagellates generally, are examined from the perspective of seeding strategies. Mismatches between observed and expected in situ bloom behaviour and resting cyst dynamics are common among upwelling dinoflagellates. This

  14. Seasonal cooling and blooming in tropical oceans

    Science.gov (United States)

    Longhurst, Alan

    1993-11-01

    The relative importance of tropical pelagic algal blooms in not yet fully appreciated and the way they are induced not well understood. The tropical Atlantic supports pelagic blooms together equivalent to the North Atlantic spring bloom. These blooms are driven by thermocline tilting, curl of wind stress and eddy upwelling as the ocean responds to intensified basin-scale winds in boreal summer. The dimensions of the Pacific Ocean are such that seasonal thermocline tilting does not occur, and nutrient conditions are such that tilting might not induce bloom, in any case. Divergence at the equator is a separate process that strengthens the Atlantic bloom, is more prominent in the eastern Pacific, and in the Indian Ocean induces a bloom only in the western part of the ocean. Where western jet currents are retroflected from the coast off Somalia and Brazil, eddy upwelling induces prominent blooms. In the eastward flow of the northern equatorial countercurrents, positive wind curl stress induces Ekman pumping and the induction of algal blooms aligned with the currents. Some apparent algal bloom, such as that seen frequently in CZCS images westwards from Senegal, must be due to interference from airborne dust.

  15. PENN neurodegenerative disease research - in the spirit of Benjamin Franklin.

    Science.gov (United States)

    Trojanowski, John Q

    2008-01-01

    Benjamin Franklin (1706-1790) was entrepreneur, statesman, supporter of the public good as well as inventor, and his most significant invention was the University of Pennsylvania (PENN). Franklin outlined his plans for a college providing practical and classical instruction to prepare youth for real-world pursuits in his 'Proposals Relating to the Education of Youth in Pensilvania' (1749), and Franklin's spirit of learning to serve society guides PENN to the present day. This is evidenced by the series of articles in this special issue of Neurosignals, describing research conducted by seasoned and newly recruited PENN faculty, addressing consequences of the longevity revolution which defines our epoch at the dawn of this millennium. While aging affects all organ systems, the nervous system is most critical to successful aging. Thus, the articles in this special issue of Neurosignals focus on research at PENN that is designed to prevent or ameliorate aging-related neurodegenerative disorders such as Alzheimer's and Parkinson's disease, amyotrophic lateral sclerosis and frontotemporal dementia. This research could enhance our chances of aging successfully in the continuing longevity revolution, and the essay here provides context and background on this research.

    Full Text Available Background: death is a fact that impacts the lives of all human beings, so that it can neither be ignored nor distanced from its subsequent bereavement period, even if being wished. The grief reaction is one of the problems that most frequently demand the assistance of health staff, especially psychologists in all health care areas.Objective: to devise a system of activities that contributes to increase the psychologists’ knowledge about bereavement and its management.Methods: a multiple cases study was carried out with the application of two research instruments (questionnaire and interview to those psychologists who work in primary and secondary health care in Las Tunas municipality to diagnose their needs related to the management of bereavement. Qualitative methodology was used, based on the method of participatory action research, and workshops were designed as forms of educational intervention.Results: it was proved that psychologists have insufficient theoretical and methodological training in relation to care for the bereaved. Consequently, psychotherapeutic workshops were designed, offering the general methodology and procedures to be followed by the professional who assists the bereaved.Conclusions: psychotherapeutic workshops constitute a referential theoretical and practical model very useful for the preparation of psychologists to deal with bereavement.

  8. Climate Change and Algal Blooms =

    Science.gov (United States)

    Lin, Shengpan

    Algal blooms are new emerging hazards that have had important social impacts in recent years. However, it was not very clear whether future climate change causing warming waters and stronger storm events would exacerbate the algal bloom problem. The goal of this dissertation was to evaluate the sensitivity of algal biomass to climate change in the continental United States. Long-term large-scale observations of algal biomass in inland lakes are challenging, but are necessary to relate climate change to algal blooms. To get observations at this scale, this dissertation applied machine-learning algorithms including boosted regression trees (BRT) in remote sensing of chlorophyll-a with Landsat TM/ETM+. The results show that the BRT algorithm improved model accuracy by 15%, compared to traditional linear regression. The remote sensing model explained 46% of the total variance of the ground-measured chlorophyll- a in the first National Lake Assessment conducted by the US Environmental Protection Agency. That accuracy was ecologically meaningful to study climate change impacts on algal blooms. Moreover, the BRT algorithm for chlorophyll- a would not have systematic bias that is introduced by sediments and colored dissolved organic matter, both of which might change concurrently with climate change and algal blooms. This dissertation shows that the existing atmospheric corrections for Landsat TM/ETM+ imagery might not be good enough to improve the remote sensing of chlorophyll-a in inland lakes. After deriving long-term algal biomass estimates from Landsat TM/ETM+, time series analysis was used to study the relations of climate change and algal biomass in four Missouri reservoirs. The results show that neither temperature nor precipitation was the only factor that controlled temporal variation of algal biomass. Different reservoirs, even different zones within the same reservoir, responded differently to temperature and precipitation changes. These findings were further

We provide a brief overview of the emergence of the history of psychology as a professional subdiscipline, describe who psychologist-historians are, explain why they are needed, and detail how to join their ranks. We argue that increasing historical sophistication among psychologists will have beneficial effects on research and teaching, and we invite all psychologists to participate in the making of psychology's history.

    Directory of Open Access Journals (Sweden)

    Shaheen E. Lakhan

    2007-07-01

    Full Text Available The privilege to prescribe pharmacotherapeutics has been granted in limited areas to psychologists. The psychologist's role in society may be approaching a great evolution that can dramatically impact the state of mental healthcare and the discipline of psychiatry. Opponents argue drug company funding and cheaper non-PhD psychological professionals fuel the movement for prescription rights for PhD level psychologists. However, proponents claim that this right would equip psychologists with greater psychotherapeutic modalities and the capability of having richer doctor-patient relationships to diagnose and treat underserved populations. Nonetheless, the paucity of prescribing psychologist studies cannot allow the biopsychosocial community to make firm opinions, let alone a decision on this debate. This article reviews the history of clinical psychology and highlights the potential divergence into collaborative clinical and health psychologists and autonomous prescribing psychologists.

    2009-11-01

    Although psychologists frequently use statistical procedures, they are often unaware of the statisticians most associated with these procedures. Learning more about the people will aid understanding of the techniques. In this article, I present a list of 10 prominent statisticians: David Cox, Bradley Efron, Ronald Fisher, Leo Goodman, John Nelder, Jerzy Neyman, Karl Pearson, Donald Rubin, Robert Tibshirani, and John Tukey. I then discuss their key contributions and impact for psychology, as well as some aspects of their nonacademic lives. © 2009 Association for Psychological Science.

    Full Text Available O conceito de mito é uma das chaves para a compreensão do pensamento de Walter Benjamin. O objetivo deste texto é reconstituir a gênese deste conceito com base em suas primeiras formulações, tal como apresentadas em Destino e caráter, texto escrito em 1919. O presente artigo se divide em duas partes: na primeira, reconstituímos os argumentos de Benjamin, a partir da filiação do conceito de destino ao domínio de uma Teoria do Direito e sua necessária inserção em um modo de "temporalidade" definido pela "repetição"; a segunda parte pretende demonstrar que as posições de Benjamin estão estreitamente ligadas a uma posição também política: seu objetivo era, em nome de um anarquismo confesso, se contrapor a todos os "mitos" nacionalistas (que levaram a Alemanha à guerra e à necessidade de "líderes", "condutores" (Führer para o povo. Como exemplo dessa perspectiva política, nos baseamos na confrontação, sempre presente, de Benjamin com o Sionismo.

    2003-01-01

    The ethical ideologies of psychologists (who provide health services) and physicians were compared using the Ethics Position Questionnaire. The findings reveal that psychologists tend to be less relativistic than physicians. Further, we explored the degree to which physicians and psychologists report being influenced by a variety of factors (e.g., family views) in their ethical decision making. Psychologists were more influenced by their code of ethics and less influenced by family views, religious background, and peer attitudes than were physicians. We argue that these differences reflect the varied professional cultures in which practitioners are trained and socialized.

  6. Obituary: Benjamin Franklin Peery Jr. (1922-2010)

    Science.gov (United States)

    Cowley, Charles

    2011-12-01

    Professor Benjamin F. Peery, Jr. died at his home in Silver Spring, MD of natural causes on 30 November 2010. His full life began in St. Joseph, MO (home of the Pony Express) on 4 March 1922. His father was a railway mail clerk, so his family moved frequently. Most of his childhood was spent in southeastern Minnesota. He enlisted in the army in 1942, and served in campaigns in North Africa and Italy. After his discharge in 1945, he enrolled in the University of Minnesota, earning a BS in Physics in 1949. One of his early hobbies was to build and fly model airplanes. His intention to pursue aeronautical engineering changed to physics, but after receiving a MS in physics from Fisk University in 1955, he decided on a career in astronomy. He told the editors of the PBS series The Astronomers (1991, in which his career is highlighted) he thought it was shamefully absurd not to know what made the stars shine. So he began PhD studies in astronomy at the University of Michigan (Ann Arbor). His dissertation was on the complex eclipsing binary VV Cephei, where a compact hot star passes behind a cool giant star, revealing the structure of that giant's atmosphere. This task was especially demanding because of the complexity of the system's spectrum and the formidable array of observations assembled by Ben's advisor, Dean McLaughlin. Fortunately, Ben's strong physics background enabled him to design and construct one of the first oscilloscope measuring engines, which his fellow students called the PeeryScope. The final (1961) dissertation is an impressive combination of observational and astrophysical analysis. His degree was obtained in 1962; he had already begun a career at the University of Indiana, where he taught and did research (1959--1976). The Indiana years were highly productive. In addition to his own research, he was advisor on six PhD dissertations, and a master's thesis. Several of his students have also had productive careers. An ADS search on his students' names

    This year marks the 60th anniversary of the American Psychologist (AP). Since the publication of its first issue in January 1946, AP has served as the flagship journal for the American Psychological Association (APA) and has played an important and unique role for the field of psychology. Because of the quality of the articles published in AP, the journal has evolved into one of the most influential and widely cited publications in psychology. The purpose of this editorial is to outline a revised set of policies for the journal that builds on and expands those developed by previous editors (see, e.g., Fowler, 1993; Goodstein, 1987; Kiesler, 1976; Pallack, 1981). Before outlining these policies, I would like to explore the relative status and influence of AP within the universe of psychological and social science journals. 2006 APA, all rights reserved.

    Grice, James; Barrett, Paul; Cota, Lisa; Felix, Crystal; Taylor, Zachery; Garner, Samantha; Medellin, Eliwid; Vest, Adam

    2017-08-14

    Four data sets from studies included in the Reproducibility Project were re-analyzed to demonstrate a number of flawed research practices (i.e., "bad habits") of modern psychology. Three of the four studies were successfully replicated, but re-analysis showed that in one study most of the participants responded in a manner inconsistent with the researchers' theoretical model. In the second study, the replicated effect was shown to be an experimental confound, and in the third study the replicated statistical effect was shown to be entirely trivial. The fourth study was an unsuccessful replication, yet re-analysis of the data showed that questioning the common assumptions of modern psychological measurement can lead to novel techniques of data analysis and potentially interesting findings missed by traditional methods of analysis. Considered together, these new analyses show that while it is true replication is a key feature of science, causal inference, modeling, and measurement are equally important and perhaps more fundamental to obtaining truly scientific knowledge of the natural world. It would therefore be prudent for psychologists to confront the limitations and flaws in their current analytical methods and research practices.

  12. South African Hindu psychologists' perceptions of mental illness.

    Padayachee, Priyanka; Laher, Sumaya

    2014-04-01

    Conceptualisations of mental illness are not universally applicable, as culture shapes the expression, perceptions and treatment preferences thereof. By focusing on the perceptions of Hindu psychologists regarding mental illness, this study aimed to provide a deeper understanding of the impact that religious beliefs have on such conceptualisations. Semi-structured interviews were conducted with six Hindu psychologists around the Johannesburg area, South Africa. Responses were analysed using thematic content analysis. From the findings, it was evident that religion plays a critical role in the understanding and treatment of mental illness. Hindu beliefs around psychological disturbances were salient. Additionally, it was found that a tension existed between psychologists' awareness of the influential function of religion, particularly amongst collectivistic communities such as the Hindu community, and their occupational understandings and practices, which are deeply rooted in Western thought. Furthermore, it was suggested that the fear of stigma prevented Hindu clients from reaping the benefits of seeking help from culturally competent psychologists.

    This research aimed to explore the role of workplace responses in psychologists' adaptation to client suicides. Participants were 178 psychologists who completed an online self-report questionnaire which included both open and closed questions yielding qualitative and quantitative data. Fifty-six (31.5%) participants reported one or more client suicides. Mixed results were found in terms of perceived support from the workplace following a client suicide. Psychologists reported a need for more open communication in the workplace, peer supports, space to grieve, as well as opportunities to engage in a learning process. The findings have important implications for research and for understanding the role of the workplace postvention. It also raises the need for external support to be accessible for psychologists working in private practice.

  16. Plankton bloom controlled by horizontal stirring

    McKiver, W.; Neufeld, Z.; Scheuring, I.

    2009-10-01

    Here we show a simple mechanism in which changes in the rate of horizontal stirring by mesoscale ocean eddies can trigger or suppress plankton blooms and can lead to an abrupt change in the average plankton density. We consider a single species phytoplankton model with logistic growth, grazing and a spatially non-uniform carrying capacity. The local dynamics have multiple steady states for some values of the carrying capacity that can lead to localized blooms as fluid moves across the regions with different properties. We show that for this model even small changes in the ratio of biological timescales relative to the flow timescales can greatly enhance or reduce the global plankton productivity. Thus, this may be a possible mechanism in which changes in horizontal mixing can trigger plankton blooms or cause regime shifts in some oceanic regions. Comparison between the spatially distributed model and Lagrangian simulations considering temporal fluctuations along fluid trajectories, demonstrates that small scale transport processes also play an important role in the development of plankton blooms with a significant influence on global biomass.

    Quantifying ocean colour properties has evolved over the past two decades from being able to merely detect their biological activity to the ability to estimate chlorophyll concentration using optical satellite sensors like MODIS and MERIS. The production of chlorophyll spatial distribution maps is a good indicator of plankton biomass (primary production) and is useful for the tracing of oceanographic currents, jets and blooms, including harmful algal blooms (HABs). Depending on the type of HA...

  19. Subsurface phytoplankton blooms fuel pelagic production in the North Sea

    DEFF Research Database (Denmark)

    Richardson, Kathrine; Visser, Andre; Pedersen, Flemming

    2000-01-01

    The seasonal phytoplankton biomass distribution pattern in stratified temperate marine waters is traditionally depicted as consisting of spring and autumn blooms. The energy source supporting pelagic summer production is believed to be the spring bloom. However, the spring bloom disappears...... relatively quickly from the water column and a large proportion of the material sedimenting to the bottom following the spring bloom is often comprised of intact phytoplankton cells. Thus, it is easy to argue that the spring bloom is fueling the energy demands of the benthos, but more difficult to argue...... convincingly that energy fixed during the spring bloom is fueling the pelagic production occurring during summer months. We argue here that periodic phytoplankton blooms are occurring during the summer in the North Sea at depths of >25 m and that the accumulated new production [sensu (Dugdale and Goering...

    Three jellyfish species, Aurelia aurita, Cyanea nozakii and Nemopilema nomurai, form large blooms in Chinese seas. We report on the distribution and increasing incidence of jellyfish blooms and their consequences in Chinese coastal seas and analyze their relationship to anthropogenically derived changes to the environment in order to determine the possible causes. A. aurita, C. nozakii and N. nomurai form blooms in the temperate Chinese seas including the northern East China Sea, Yellow Sea and Bohai Sea. N. nomurai forms offshore blooms while the other two species bloom mainly in inshore areas. Eutrophication, overfishing, habitat modification for aquaculture and climate change are all possible contributory factors facilitating plausible mechanisms for the proliferation of jellyfish blooms. In the absence of improvement in coastal marine ecosystem health, jellyfish blooms could be sustained and may even spread from the locations in which they now occur.

  1. A psychologist's view of validating aviation systems

    Stein, Earl S.; Wagner, Dan

    1994-01-01

    All systems, no matter what they are designed to do, have shortcomings that may make them less productive than was hoped during the initial development. Such shortcomings can arise at any stage of development: from conception to the end of the implementation life cycle. While systems failure and errors of a lesser magnitude can occur as a function of mechanical or software breakdown, the majority of such problems, in aviation are usually laid on the shoulders of the human operator and, to a lesser extent, on human factors. The operator bears the responsibility and blame even though, from a human factors perspective, error may have been designed into the system. Human factors is not a new concept in aviation. The name may be new, but the issues related to operators in the loop date back to the industrial revolution of the nineteenth century and certainly to the aviation build-up for World War I. During this first global confrontation, military services from all sides discovered rather quickly that poor selection and training led to drastically increased personnel losses. While hardware design became an issue later, the early efforts were primarily focused on increased care in pilot selection and on their training. This actually involved early labor-intensive simulation, using such devices as sticks and chairs mounted on rope networks which could be manually moved in response to control input. The use of selection criteria and improved training led to more viable person-machine systems. More pilots survived training and their first ten missions in the air, a rule of thumb arrived at by experience which predicted ultimate survival better than any other. This rule was to hold through World War II. At that time, personnel selection and training became very sophisticated based on previous standards. Also, many psychologists were drafted into Army Air Corps programs which were geared towards refining the human factor. However, despite the talent involved in these programs

    Algal bloom is defined as a rapid increase or accumulation in biomass in an aquatic system. It not only can increase the primary production but also could result in negative ecological consequence, e.g.,Harmful Algal Blooms (HABs). According to the classic theory for the formation of algal blooms "critical depth" and "eutrophication", oligotrophic sea area is usually difficult to form a large area of algal blooms, and actuallythe traditional observation is only sporadic capture to the existence of algal blooms.Taking full advantage of multiple data of satellite remote sensing , this study introduces "Wind-driven algal blooms in open oceans: observation and mechanisms" It explained except classic coastal Ekman transport, the wind through a variety of mechanisms affecting the formation of algal blooms. Proposed a conceptual model of "Strong wind -upwelling-nutrient-phytoplankton blooms" in Western South China Sea (SCS) to assess role of wind-induced advection transport in phytoplankton bloom formation. It illustrates the nutrient resources that support long-term offshore phytoplankton blooms in the western SCS; (2)Proposal of the theory that "typhoons cause vertical mixing, induce phytoplankton blooms", and quantify their important contribution to marine primary production; Proposal a new ecological index for typhoon. Proposed remote sensing inversion models. (3)Finding of the spatial and temporaldistributions pattern of harmful algal bloom (HAB)and species variations of HAB in the South Yellow Sea and East China Sea, and in the Pearl River estuary, and their oceanic dynamic mechanisms related with monsoon; The project developed new techniques and generated new knowledge, which significantly improved understanding of the formation mechanisms of algal blooms. The proposed "wind-pump" mechanism integrates theoretical system combined "ocean dynamics, development of algal blooms, and impact on primary production", which will benefit fisheries management.

    Freshwater lakes provide a number of significant ecological services including clean drinking water, habitat for aquatic biota, and economic benefits. The provision of these ecological services, as well as the health of these aquatic systems, is threatened by the excessive growth of algae, specifically, cyanobacteria. Historically, blooms have been linked to eutrophication but recent occurrences indicate that there are less dramatic changes that induce these blooms. Iron is an essential micronutrient required for specific essential metabolic pathways; however, the amount of biologically available iron in naturally occurring lake ranges from saturation to much lower than cell transport affinities. To assist in the modulation of iron availabilities, cyanobacteria in culture produce low molecular weight compounds that function in an iron binding and acquisition system; nevertheless, this has yet to be confirmed in naturally occurring lakes. This project explored the relationship of P, N and in particular, Fe, in the promotion of cyanobacteria harmful algal blooms in 30 natural freshwater lakes located in and around the Elk Island National Park, Alberta. It is hypothesized that cyanobacteria produce and utilize iron chelators called siderophores in low Fe and nitrogen (N) conditions, creating a competitive advantage over other algae in freshwater lakes. Lakes were selected to represent a range of iron availability to explore the nutrient composition of lakes that propagated cyanobacteria harmful algal blooms (cHABs) compared to lakes that did not. Lake water was analyzed for nutrients, microbial composition, siderophore concentration, and toxin concentration. Modifications were made to optimize the Czaky and Arnow tests for hydroxamate- and catecholate-type siderophores, respectively, for field conditions. Preliminary results indicate the presence of iron-binding ligands (0.11-2.34 mg/L) in freshwater lakes characterized by widely ranging Fe regimes (0.04-2.74 mg

    In this paper, we study the decay rates of solutions for the generalized Benjamin-Bona-Mahony equation in multi-dimensional space. For initial data in some L1-weighted spaces, we prove faster decay rates of the solutions. More precisely, using the Fourier transform and the energy method, we show the global existence and the convergence rates of the solutions under the smallness assumption on the initial data and we give better decay rates of the solutions.

    Whitham modulation theory for the two-dimensional Benjamin-Ono (2DBO) equation is presented. A system of five quasilinear first-order partial differential equations is derived. The system describes modulations of the traveling wave solutions of the 2DBO equation. These equations are transformed to a singularity-free hydrodynamic-like system referred to here as the 2DBO-Whitham system. Exact reductions of this system are discussed, the formulation of initial value problems is considered, and the system is used to study the transverse stability of traveling wave solutions of the 2DBO equation.

    After revelations of participation by psychiatrists and psychologists in interrogation of prisoners at Guantánamo Bay and Central Intelligence Agency secret detention centers, the American Psychiatric Association and the American Psychological Association adopted Position Statements absolutely prohibiting their members from participating in torture under any and all circumstances, and, to a limited degree, forbidding involvement in interrogations. Some interrogations utilize very aggressive techniques determined to be torture by many nations and organizations throughout the world. This paper explains why psychiatrists and psychologists involved in coercive interrogations violate the Geneva Conventions and the laws of the United States. Whether done with ignorance of professional ethical obligations or not, these psychiatrists and psychologists have crossed an ethical barrier that may best be averted from re-occurring by teaching medical students and residents in all medical specialties about the ethics principles stemming from the 1946-1947 Nuremberg trials and the Geneva Conventions, together with the Ethics Codes of the World Medical Association and the American Medical Association; and, with regard to psychiatric residents and psychological trainees, by the teaching about The Principles of Medical Ethics With Annotations Especially Applicable to Psychiatry and the Ethical Principles of Psychologists and Code of Conduct, respectively. In this way, all physicians and psychologists will clearly understand that they have an absolute moral obligation to "First, do no harm" to the human beings they professionally encounter.

  14. New Coccolithophore Bloom in Bering Sea

    2002-01-01

    For the fourth year in a row it appears as if there is a bloom of coccolithophores-marine single-celled plants with calcite scales-in the Bering Sea off the coast of Alaska. Similar blooms were rare before 1997, but they have appeared every year since then. Scientists believe the coccolithophore blooms are the result of changing wind patterns in the region. Weaker than normal winds fail to mix the water of the Bering Sea, resulting in the growth of coccolithophores instead of other types of phytoplankton. Seabird populations have also been changing as a result of this climate change. The Sea-Viewing Wide Field-of-View Sensor (SeaWiFS), flying aboard the OrbView-2 satellite, saw the coccolith-brightened waters of the Bering Sea in 1997, 1998, and 1999. The waters have looked fairly bright again this winter and spring, as seen in this SeaWiFS image acquired April 29, 2000. But scientists are unsure whether this year's phenomenon is caused by living coccolithophorids, re-suspended coccoliths, or something else. Like all phytoplankton, coccolithophores contain chlorophyll and have the tendency to multiply rapidly near the surface. Yet, in large numbers, coccolithophores periodically shed their tiny scales, called 'coccoliths,' by the bucketful into the surrounding waters. The calcium-rich coccoliths turn the normally dark water a bright, milky aquamarine, making coccolithophore blooms easy to spot in satellite imagery. The edge of the whitish cloud in the water seen in this image is roughly 50 kilometers off the West Coast of Alaska.

  15. Critica e derive del mito nell’opera di Walter Benjamin

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available La ri essione critica sul mito e sulle sue derive nel mondo moderno sono pre- senti in buona parte del pensiero benjaminiano. A cominciare dagli scritti di filosofia del linguaggio nei quali il mito biblico istituisce il fondamento ontologico della parola originaria, tra rifiuto della storia e messianismo, fino alle considerazioni sul diritto e sul concetto di destino nella società borghese. Ma è soprattutto nella critica letteraria che Benjamin espone le sue più brillanti intuizioni: dallo sprigionarsi delle forze primordiali della natura che, nelle Affinità elettive di Goethe, tra violenza del diritto e libertà etica, si impossessano dei personaggi, alla dialettica del “risveglio” con Proust e i surrealisti, e all’esperienza profonda della vie antérieur di Baudelaire. Così, senza mai distanziarsi dal radicamento della condizione storica del suo tempo e senza mai cadere in facile misticismo, Walter Benjamin ha acutamente ispezionato le tracce del mito nella modernità, auspicando con intelligenza la liberazione umana dalla schiavitù della barbarie contingenti.

    Full Text Available The authors analyze the 16 early writings that W. Benjamin wrote between the ages of 19 and 23, all of which relate to educative matters, and where the decisive influence of G. Wyneken is shown. The issues that the young Walter Benjamin addresses are also studied, such as idealism and youth culture, the necessity of reform in schools and universities and also in moral, aesthetic and religious education as well as in juvenile sexuality. However, the most important thing is that in these works one can find the constants that characterize the rest of his production, such as his individualism, his obsession with his own childhood experiences, his contradictions and thematic transitions, his interest in aesthetics and art, the complexity of his work, his agnosticism and his consideration of Judaism as a cultural element, and above all his critical sense and his vocation for criticism which starts to become evident. Somehow in these articles of educative content one can discover many of the constants of what will be the subsequent work of this author.

    2009-01-01

    In the aftermath of 9-11, the American Psychological Association, one of the largest U.S. health professions, changed its ethics code so that it now runs counter to the Nuremberg Ethic. This historic post-9-11 change allows psychologists to set aside their ethical responsibilities whenever they are in irreconcilable conflict with military orders, governmental regulations, national and local laws, and other forms of governing legal authority. This article discusses the history, wording, rationale, and implications of the ethical standard that U.S. psychologists adopted 7 years ago, particularly in light of concerns over health care professionals' involvement in detainee interrogations and the controversy over psychologists' prominent involvement in settings like the Guantánamo Bay Detainment Camp and the Abu Ghraib prison. It discusses possible approaches to the complex dilemmas arising when ethical responsibilities conflict with laws, regulations, or other governing legal authority.

    To examine trends in the psychologist workforce and training opportunities, including factors that may influence the decision of clinical psychologists to practice in rural settings. We use a mixed-methods approach to examine the psychologist workforce nationally and in North Carolina (NC), including (1) an analysis of the location of programs awarding doctoral degrees; (2) an analysis of the practice, demographic, and educational characteristics of the psychologist workforce; and (3) interviews with directors of doctoral programs in clinical psychology to understand where current graduates are getting jobs and why they may or may not be choosing to practice in rural communities. Fewer than 1% of programs and institutions awarding doctoral degrees in psychology in the United States are located in rural areas. In NC, approximately 80% of practicing psychologists have out-of-state degrees and about 80% of recent NC graduates are not currently licensed in the state. This juxtaposition undermines the utility of adding more in-state degree programs. While expansion of training programs within rural areas could help alleviate the shortages of mental health providers, adding new degree-granting programs alone will not necessarily increase supply. We discuss complementary recruitment and retention strategies, including greater incentives for rural training and practice as well as training in emerging technologies that don't require providers to be physically located in underserved areas, such as telemedicine. Increasing the supply of psychologists practicing in rural areas will require a thoughtful, multipronged approach to training this critical part of the behavioral health workforce. © 2018 National Rural Health Association.

    The aim of this study was to investigate the use of de-blooming algorithm in coronary CT angiography (CCTA) for optimal evaluation of calcified plaques. Calcified plaques were simulated on a coronary vessel phantom and a cardiac motion phantom. Two convolution kernels, standard (STND) and high-definition standard (HD STND), were used for imaging reconstruction. A dedicated de-blooming algorithm was used for imaging processing. We found a smaller bias towards measurement of stenosis using the de-blooming algorithm (STND: bias 24.6% vs 15.0%, range 10.2% to 39.0% vs 4.0% to 25.9%; HD STND: bias 17.9% vs 11.0%, range 8.9% to 30.6% vs 0.5% to 21.5%). With use of de-blooming algorithm, specificity for diagnosing significant stenosis increased from 45.8% to 75.0% (STND), from 62.5% to 83.3% (HD STND); while positive predictive value (PPV) increased from 69.8% to 83.3% (STND), from 76.9% to 88.2% (HD STND). In the patient group, reduction in calcification volume was 48.1 ± 10.3%, reduction in coronary diameter stenosis over calcified plaque was 52.4 ± 24.2%. Our results suggest that the novel de-blooming algorithm could effectively decrease the blooming artifacts caused by coronary calcified plaques, and consequently improve diagnostic accuracy of CCTA in assessing coronary stenosis.

    Pseudo-nitzschia blooms often occur in coastal and open ocean environments, sometimes leading to the production of the neurotoxin domoic acid that can cause severe negative impacts to higher trophic levels. Increasing evidence suggests a close relationship between phytoplankton bloom and bacterial assemblages, however, the microbial composition and succession during a bloom process is unknown. Here, we investigate the bacterial assemblages before, during and after toxic and non-toxic Pseudo-nitzschia blooms to determine the patterns of bacterial succession in a natural bloom setting. Opportunistic sampling of bacterial community profiles were determined weekly at Santa Cruz Municipal Wharf by 454 pyrosequencing and analyzed together with domoic acid levels, phytoplankton community and biomass, nutrients and temperature. We asked if the bacterial communities are similar between bloom and non-bloom events and if domoic acid or the presence of toxic algal species acts as a driving force that can significantly structure phytoplankton-associated bacterial communities. We found that bacterial diversity generally increases when Pseudo-nitzschia numbers decline. Furthermore, bacterial diversity is higher when the low-DA producing P. fraudulenta dominates the algal bloom while bacterial diversity is lower when high-DA producing P. australis dominates the algal bloom, suggesting that the presence of algal toxin can structure bacterial community. We also found bloom-related succession patterns among associated bacterial groups; Gamma-proteobacteria, were dominant during low toxic P. fraudulenta blooms comprising mostly of Vibrio spp., which increased in relative abundance (6-65%) as the bloom progresses. On the other hand, Firmicutes bacteria comprising mostly of Planococcus spp. (12-86%) dominate during high toxic P. australis blooms, with the bacterial assemblage showing the same bloom-related successional patterns in three independent bloom events.

The report discusses the physics of the laser-absorber interaction, the numerical approximation used, and comparisons with experimental data. A flowchart is supplied in the appendix to the report.

  19. Control and Stabilization of the Benjamin-Ono Equation in {L^2({{T})}}

    Science.gov (United States)

    Laurent, Camille; Linares, Felipe; Rosier, Lionel

    2015-12-01

    We study the control and stabilization of the Benjamin-Ono equation in {L^2({T})}, the lowest regularity where the initial value problem is well-posed. This problem was already initiated in Linares and Rosier (Trans Am Math Soc 367:4595-4626, 2015) where a stronger stabilization term was used (that makes the equation of parabolic type in the control zone). Here we employ a more natural stabilization term related to the L 2-norm. Moreover, by proving a theorem of controllability in L 2, we manage to prove the global controllability in large time. Our analysis relies strongly on the bilinear estimates proved in Molinet and Pilod (Anal PDE 5:365-395, 2012) and some new extension of these estimates established here.

  20. Structural stability and chaotic solutions of perturbed Benjamin-Ono equations

    International Nuclear Information System (INIS)

    Birnir, B.; Morrison, P.J.

    1986-11-01

    A method for proving chaos in partial differential equations is discussed and applied to the Benjamin-Ono equation subject to perturbations. The perturbations are of two types: one that corresponds to viscous dissipation, the so-called Burger's term, and one that involves the Hilbert transform and has been used to model Landau damping. The method proves chaos in the PDE by proving temporal chaos in its pole solutions. The spatial structure of the pole solutions remains intact, but their positions are chaotic in time. Melnikov's method is invoked to show this temporal chaos. It is discovered that the pole behavior is very sensitive to the Burger's perturbation, but is quite insensitive to the perturbation involving the Hilbert transform

  1. Benjamin Franklin's risk factors for gout and stones: from genes and diet to possible lead poisoning.

    Science.gov (United States)

    Finger, Stanley; Hagemann, Ian S

    2008-06-01

    Benjamin Franklin's medical history shows that he suffered from repeated attacks of gout and a large bladder stone. These conditions caused him considerable pain, markedly decreased his mobility, and likely contributed in indirect ways to his decline and eventual death from a pulmonary disorder. This article examines Franklin's risk factors for gout and stones, both as Franklin understood them and as we know them today. Significantly, both of these disorders are associated with high blood levels of uric acid, a metabolic by-product. Franklin's risk factors included his gender, genetics, diet, drinking, advanced age, psoriasis, and exposure to lead. Although it is impossible to assign a weight to each of these factors, it can be shown that a number of factors, each capable of raising uric acid levels, converged and conspired against him.

El cotejo con algunos de los naturwissenschaftliche Schriften de Goethe sugiere que ambos autores aventuran una manera de pensar la relación entre los conceptos de verdad y totalidad a través de la confrontación y manipulación forzosa de las distinciones introducidas por la filosofía crítica de Kant. En este sentido sus esbozos lógicos y epistemológicos se dejan leer como marcadores de los momentos inaugural y concluyente del proyecto del idealismo alemán.

A comparison with some of Goethe’s naturwissenschaftliche Schriften suggests that both authors suggest a way of thinking the relation between the concepts of truth and totality, by means of a confrontation and forceful manipulation of distinctions introduced in Kant’s critical philosophy. In this sense, their logical and epistemological sketches can be read as markers for the inaugural and closing moments of the project of German idealism.

    The Benjamin H. Kean Fellowship in Tropical Medicine is an American Society of Tropical Medicine and Hygiene initiative that provides medical students with funding for international clinical or research experiences lasting at least 1 month. Of the 175 Kean fellows from 1998 to 2013, 140 had current available e-mails, and 70 of the 140 (50%) responded to a survey about their fellowship experience. Alumni indicated that the Kean Fellowship had a high impact on their career plans with regard to preparation for ( N = 65, 94.2%) and inspiration to pursue ( N = 59, 88.1%) a career in tropical medicine and global health. Continued involvement in tropical medicine and global health was common: 52 alumni (74.3%) were currently working in tropical medicine or global health, 49 (71.0%) had done so in the interim between the Kean fellowship and their current position; and 17 of 19 Kean fellows (89.4%) who had completed all medical training and were now in professional practice continued to work in tropical medicine and global health. Alumni had been highly productive academically, publishing a total of 831 PubMed-indexed manuscripts, almost all on tropical medicine or global health topics, in the period between their fellowship year and 2013. Alumni reported strengths of the fellowship including funding, networking, and flexibility, and suggested that more networking and career mentoring would enhance the program. The Benjamin H. Kean fellowship program has been highly successful at inspiring and fostering ongoing work by trainees in tropical medicine and global health.

    Full Text Available O ensaio traz como base a crítica ao capitalismo, no que se refere aos efeitos negativos que ele impõe aos indivíduos, a partir dos estudos da primeira geração da Escola de Frankfurt. Analisar-se-á a história das ideias a partir de Walter Benjamin, Herbert Marcuse, Theodor Adorno e Max Horkheimer. Benjamin afirma que vive-se a perda da aura das obras de arte, já que a sua comercialização faz com que se perca a essência daquelas obras. Ademais, a imposição da novidade às obras e aos produtos consumidos representa uma ferramenta de manipulação do capitalismo, culminando na pobreza da experiência humana. Marcuse afirma que a sociedade vive o princípio do desempenho, que provoca modos de vida uniformizados, baseados numa concepção de trabalho e diversão homogêneos. Adorno propôs que o tempo livre provocava uma sensação de liberdade nos indivíduos, mas, na realidade, tratava-se do exercício de uma não liberdade, já que as formas de diversão seguiam à risca os padrões exigidos pelo capital. A partir do método adotado pela própria Teoria Crítica, afirma-se que a presente discussão teórica só se torna efetiva quando aplicada à prática, à sociedade atual.

  7. Margalef's mandala and phytoplankton bloom strategies

    Science.gov (United States)

    Wyatt, Timothy

    2014-03-01

    Margalef's mandala maps phytoplankton species into a phase space defined by turbulence (A) and nutrient concentrations (Ni); these are the hard axes. The permutations of high and low A and high and low Ni divide the space into four domains. Soft axes indicate some ecological dynamics. A main sequence shows the normal course of phytoplankton succession; the r-K axis of MacArthur and Wilson runs parallel to it. An alternative successional sequence leads to the low A-high Ni domain into which many red tide species are mapped. Astronomical and biological time are implicit. A mathematical transformation of the mandala (rotation) links it to the classical bloom models of Sverdrup (time) and Kierstead and Slobodkin (space). Both rarity and the propensity to form red tides are considered to be species characters, meaning that maximum population abundance can be a target of natural selection. Equally, both the unpredictable appearance of bloom species and their short-lived appearances may be species characters. There may be a correlation too between these features and long-lived dormant stages in the life-cycle; then the vegetative planktonic phase is the 'weak link' in the life-cycle. Red tides are thus due to species which have evolved suites of traits which result in specific demographic strategies.

    2012-01-01

    Bacterioplankton consume a large proportion of photosynthetically fixed carbon in the ocean and control its biogeochemical fate. We used an experimental metatranscriptomics approach to compare bacterial activities that route energy and nutrients during a phytoplankton bloom compared with non-bloom conditions. mRNAs were sequenced from duplicate bloom and control microcosms 1 day after a phytoplankton biomass peak, and transcript copies per litre of seawater were calculated using an internal mRNA standard. Transcriptome analysis revealed a potential novel mechanism for enhanced efficiency during carbon-limited growth, mediated through membrane-bound pyrophosphatases [V-type H(+)-translocating; hppA]; bloom bacterioplankton participated less in this metabolic energy scavenging than non-bloom bacterioplankton, with possible implications for differences in growth yields on organic substrates. Bloom bacterioplankton transcribed more copies of genes predicted to increase cell surface adhesiveness, mediated by changes in bacterial signalling molecules related to biofilm formation and motility; these may be important in microbial aggregate formation. Bloom bacterioplankton also transcribed more copies of genes for organic acid utilization, suggesting an increased importance of this compound class in the bioreactive organic matter released during phytoplankton blooms. Transcription patterns were surprisingly faithful within a taxon regardless of treatment, suggesting that phylogeny broadly predicts the ecological roles of bacterial groups across 'boom' and 'bust' environmental backgrounds. © 2011 Society for Applied Microbiology and Blackwell Publishing Ltd.

    Full Text Available The massive development of bluegreen algae (Cyanophyta/Cyanobacteria, the so--called water bloom, is a frequent phenomenon in fishpond ecosystems. This study analyses water bloom development in three carp fishponds owned by a fishbreeding company at Donji Miholjac (Croatia, where one-year-old carps (Cyprinus carpio , were bred in defferent fishstock densities. Analyses of physicallychemical properties of water and phytoplankton biomass were per- formed in fortnight intervals from May till October, 1992. In all there investigated fishponds the water bloom of bluegreen algae developed, but at a different time and showing a different qualitative composition. In the fishpond with fishstock density of 250 kg/ha water bloom consisted of the species Aphanizomenon flos-aquae, and the biggest biomass (131.92 mg/I was found in August. In the fishpond with fishstock density of 437 kg/ha a water bloom consisting of species from the genues Anabaena and species Aphanizomenon flos-aquae developed at the end of July. In the fishpond with the so--called intensive breeding (fishstock density of 750 kg/ha water bloom of the species Microcystis aeruginosa developed as late as September. The beginning of water bloom development was caused by the low value (lower than 7 of the ratio between the quantities of total phosphorus and total nitrogen. However, the qualitative composition of water bloom was influenced by one-year-old carp fingerlings density.

  2. Ricardo Piglia lector de Walter Benjamin: compromiso político y vanguardia artística en los 70 argentinos.

    Directory of Open Access Journals (Sweden)

    Luis Ignacio García García

    2014-03-01

    This paper analyzes the reception of Walter Benjamin by the young Ricardo Piglia. Walter Benjamin, together with Bertolt Brecht, was very important for Piglia’s self-comprehension in the context of the agitated aesthetical-political debates of the ’60s and ’70s. Piglia makes use of the Brechtian Benjamin to articulate aesthetics and politics in a way that singles out his critical work in those years. He builds, from the parameters of a production aesthetic, a position that goes beyond not only the idealistic aesthetics but also the principles of the socialist realism, putting aside the opposition between aesthetic experimentation and politicization of art.

  3. Deep-Learning-Based Approach for Prediction of Algal Blooms

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Algal blooms have recently become a critical global environmental concern which might put economic development and sustainability at risk. However, the accurate prediction of algal blooms remains a challenging scientific problem. In this study, a novel prediction approach for algal blooms based on deep learning is presented—a powerful tool to represent and predict highly dynamic and complex phenomena. The proposed approach constructs a five-layered model to extract detailed relationships between the density of phytoplankton cells and various environmental parameters. The algal blooms can be predicted by the phytoplankton density obtained from the output layer. A case study is conducted in coastal waters of East China using both our model and a traditional back-propagation neural network for comparison. The results show that the deep-learning-based model yields better generalization and greater accuracy in predicting algal blooms than a traditional shallow neural network does.

    A bloom of the harmful marine phytoplankton, Heterosigma carterae occurred in upper Case Inlet, south Puget Sound, Washington in late September, 1994, correlating with the presence of at least 35 dead salmon. This marks the first time that this alga has been closely correlated with a wild fish kill; in the past it was thought to be associated with kills of penned fish at fish farms only. We were informed of the presence of a possible harmful algal bloom and dead salinois Ilear the town of Allyn on 27 September and a team was formed to investigate. We arrived at the Allyn waterfront at 17:30 hours the same day. Prior to our arrival, state agency personnel walked approximatcly two miles of shoreline from the powerlines north of the dock, to the mouth of Sherwood Creek and conducted the only official count of dead fish present along the shore consisting of 12 coho salmon (Oncorhynchus kisutch), 11 chum salmon (Oncorhynchus keta), 12 chinook salmon (Oncorhynchus tschawytscha), one flat fish, and one sculpin on the morning of 9/27. Since previous harmful blooms of Heterosigma have resultedin the majority of net penreared salmon sinking to the bottom of pens, and only approximately two miles of shoreline were sampled, it is suspected that many more exposed fish may have succumbed than were counted. Witnesses who explored the east side of the bay reported seeing many dead salmon there as well, but no counts were made. State agency personnel who observed the fish kill reported seeing “dying fish coming to the beach, gulping at the surface, trying to get out of the water” Scavengers were seen consuming the salmon carcasses; these included two harbor seals, a house cat, and Hymenopteran insects. None suffered any noticeable acute ill effects. Although precise cause of death has not been ascertained, visual inspection of the reproductive organs from a deceased male chum salmon found on the shore at Allyn confirmed that the fish was not yet reproductively mature and

    The five most commonly recognized Harmful Algal Bloom related illnesses include Ciguatera poisoning, Paralytic Shellfish poisoning, Neurotoxin Shellfish poisoning, Diarrheic Shellfish Poisoning and Amnesic Shellfish poisoning. Although they are each the product of different toxins, toxin assemblages or HAB precursors these clinical syndromes have much in common. Exposure occurs through the consumption of fish or shellfish; routine clinical tests are not available for diagnosis; there is no known antidote for exposure; and the risk of these illnesses can negatively impact local fishing and tourism industries. Thus, illness prevention is of paramount importance to minimize human and public health risks. To accomplish this, close communication and collaboration is needed among HAB scientists, public health researchers and local, state and tribal health departments at academic, community outreach, and policy levels.

  9. Fast lossless compression via cascading Bloom filters.

    2014-01-01

    Data from large Next Generation Sequencing (NGS) experiments present challenges both in terms of costs associated with storage and in time required for file transfer. It is sometimes possible to store only a summary relevant to particular applications, but generally it is desirable to keep all information needed to revisit experimental results in the future. Thus, the need for efficient lossless compression methods for NGS reads arises. It has been shown that NGS-specific compression schemes can improve results over generic compression methods, such as the Lempel-Ziv algorithm, Burrows-Wheeler transform, or Arithmetic Coding. When a reference genome is available, effective compression can be achieved by first aligning the reads to the reference genome, and then encoding each read using the alignment position combined with the differences in the read relative to the reference. These reference-based methods have been shown to compress better than reference-free schemes, but the alignment step they require demands several hours of CPU time on a typical dataset, whereas reference-free methods can usually compress in minutes. We present a new approach that achieves highly efficient compression by using a reference genome, but completely circumvents the need for alignment, affording a great reduction in the time needed to compress. In contrast to reference-based methods that first align reads to the genome, we hash all reads into Bloom filters to encode, and decode by querying the same Bloom filters using read-length subsequences of the reference genome. Further compression is achieved by using a cascade of such filters. Our method, called BARCODE, runs an order of magnitude faster than reference-based methods, while compressing an order of magnitude better than reference-free methods, over a broad range of sequencing coverage. In high coverage (50-100 fold), compared to the best tested compressors, BARCODE saves 80-90% of the running time while only increasing space

    Cyanobacterial blooms dominated by Microcystis sp. occurred in lake Rocuant ("marisma", near Concepción/Chile) in February 1995 and 1996. In the bloom samples collected in both years the hepatotoxin microcystin was detected by RP-HPLC in both samples and in the sample of 1995 also by a toxicity assay using primary rat hepatocytes. In the bloom of 1995, the microcystin content of the dry bloom biomass was determined to be 130 micrograms/g on the basis of the RP-HPLC peak area and 800 micrograms/g on the basis of the rat hepatotoxicity assay, respectively. In the bloom of 1996, RP-HPLC analysis revealed a microcystin content of 8.13 micrograms/g bloom material dry weight. In this year no hepatotoxicity was measured using a concentration range up to 0.8 mg (d. w.) of bloom material per ml in the rat hepatotoxicity assay. This is the first report on the detection of microcystins in Chilean water bodies.

  11. Un taccuino a forma di strada. Su "Einbahnstrasse" di Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Pier Giovanni Adamo

    2016-05-01

    Full Text Available La poetica di F. Schlegel ha realizzato una storicizzazione della teoria dei generi letterari sostituendo alla dicotomia del classicismo tra forma e contenuto una distinzione tra forma e spirito, secondo cui i materiali linguistico-tematici rappresentano i precipitati di quest’ultimo. Riprendendo questa intuizione di P. Szondi, potremmo affermare che, nella modernità letteraria, l’ibridazione è il processo di transizione dei materiali attraverso le forme. Un’opera tanto esemplare quanto strutturalmente rilevante, nell’orizzonte dell’ibridazione, è Einbahnstraße di Walter Benjamin, dove i materiali più disparati sono combinati a modellare una forma innovativa. Vi si mescolano stilemi della poesia in prosa, narrazione diaristica, (antimetodo surrealista, satira e intuizioni filosofiche. L’unicità, d’altra parte, risiede innanzitutto nell’essenza metacritica del procedimento organizzativo del libro: il frammentismo sistematico è un’applicazione pratica della teoria allegorica del montaggio, descritta nell’Ursprung des deutschen Trauerspiels. Il saggio si propone di leggere il testo come «un taccuino a forma di strada», anche per indagarne il valore di prologo al Passagenwerk, nato dall’avida lettura del Paysan de Paris di Aragon: istituisce un confronto per rilevare, nell’affinità di fondo, la  diversità di approccio tra il pensatore tedesco e il surrealismo, distinguendo tecniche di assemblaggio e ruolo dell’immaginario nell’uso di pubblicità e altri oggetti metropolitani. L’intenzione di una simile analisi di Einbahnstraße è dimostrare che Benjamin combina modelli letterari (Baudelaire, Proust, Kraus su tutti con i nuovi linguaggi artistici e le strategie discorsive della stampa per creare un’«immagine dialettica» dell’esistenza nel XX secolo.Friedrich Schlegel’s poetics realized a historicisation of literary genres theory by replacing classicist dichotomy between form and content with a

    Monitoring flower development can provide useful information for production management, estimating yield and selecting specific genotypes of crops. The main goal of this study was to develop a methodology to detect and count cotton flowers, or blooms, using color images acquired by an unmanned aerial system. The aerial images were collected from two test fields in 4 days. A convolutional neural network (CNN) was designed and trained to detect cotton blooms in raw images, and their 3D locations were calculated using the dense point cloud constructed from the aerial images with the structure from motion method. The quality of the dense point cloud was analyzed and plots with poor quality were excluded from data analysis. A constrained clustering algorithm was developed to register the same bloom detected from different images based on the 3D location of the bloom. The accuracy and incompleteness of the dense point cloud were analyzed because they affected the accuracy of the 3D location of the blooms and thus the accuracy of the bloom registration result. The constrained clustering algorithm was validated using simulated data, showing good efficiency and accuracy. The bloom count from the proposed method was comparable with the number counted manually with an error of -4 to 3 blooms for the field with a single plant per plot. However, more plots were underestimated in the field with multiple plants per plot due to hidden blooms that were not captured by the aerial images. The proposed methodology provides a high-throughput method to continuously monitor the flowering progress of cotton.

    2017-03-01

    Full Text Available The aim of this work is to trace a journey through the work of Walter Benjamin to give account of the existence of an incipient critical theory of consumption that appears, dispersed and fragmented among their major concerns as the status of the work of art, industrial technology or modern city. The idea that we intend to show is that the originality of Benjamin's proposal lies in the indirect nature by which access to the cultural question. Not so much as an instance derived from the production process determinations but from the transformations in the sphere of consumption. So the Arcades-Project can be read as a historic attempt to develop the contradiction of the commodity form that the consumer experience is presented as the cynical and utopian moment.

    Full Text Available Cet article analyse le Tricentenaire de Benjamin Franklin, qui eut lieu de 2006 à 2008. A l’occasion de cette date anniversaire, de nombreux livres furent publiés, des colloques et expositions organisés aux Etats-Unis. Ces travaux et manifestations ont produit un nouveau regard, critique, sur Franklin, père fondateur assez extraordinaire. L’exposition principale est venue à Paris, au cours de l’hiver 2007-2008, clairement dans le cadre d’une volonté de rapprocher les deux pays à la suite des controverses suscitées par la Guerre en Irak. Cette commémoration franco-américaine a eu comme objectif principal de souligner la diplomatie et la collaboration transatlantiques, et non de présenter Franklin sous toutes ses facettes, et de l’intégrer au contexte de son époque dans son pays. Un symposium fut donc organisé à l’Université Paris – Diderot afin de mettre en valeur les travaux scientifiques sur Franklin, français, mais aussi étrangers. Les principales communications sont présentées dans ce dossier.This paper offers reflections on the Benjamin Franklin Tercentenary, which took place from 2006 to 2008. This anniversary was celebrated by many publications, conferences and exhibitions in the United States, producing a renewed and critical understanding of Franklin, “not your usual founding father”. The main exhibition travelled to France (2007-2008, clearly as part of an attempt to patch up relationships between the two countries in the wake of the Iraq war controversy. The main focus in this Franco-American commemoration was on transatlantic diplomacy and collaboration, not really on Franklin in his multiple capacities, in his time and country of birth. The conference organized at Université Paris-Diderot in January 2008 was by contrast a scholarly affair, highlighting work on Franklin conducted by French and foreign specialists. Most of the papers are presented here.

    Cyanobacteria bloom is a great ecological problem of Curonian Lagoon and Baltic Sea. The development of novel methods for the on-line control of cyanobacteria concentration and, moreover, for prediction of bloom spreading is of interest for monitoring the state of ecosystem. Here, we report the results of the joint application of hyperspectral measurements and remote sensing of Curonian Lagoon in July 2015 aimed at the assessment of cyanobacteria communities. We show that hyperspectral data allow on-line detection and qualitative estimation of cyanobacteria concentration, while the remote sensing data indicate the possibility of cyanobacteria bloom detection using the spectral features of upwelling irradiation.

    Directory of Open Access Journals (Sweden)

    Christian Ferencz-Flatz

    2010-06-01

    Full Text Available In his famous essay, The Work of Art in the Age of Mechanical Reproduction, Walter Benjamin compares the daily experience of buildings with the perception of films. His comparison relies on the peculiar concept of “tactile reception“, he opposes to the optically oriented traditional attitude towards art. The concept encompasses two essential traits: on the one hand, it designates the fact that films do not require a contemplative, focused attention, but a habitual, distracted approach, similar to that by which we perceive buildings in our everyday life-world. On the other hand, Benjamin’sconcept points to a particular “chock-effect” produced by cinematic experience, through its constant change of perspectives and points of view. By this, it challenges precisely the same form of ambient perception required in numerous situations of our daily life in the modern city. The two determinations sketch out a unitary concept that shows obvious similarities to the phenomenological idea of a “life-worldly circumspection” (Umsicht, a specific manner of sight guiding everyday practical life.

  20. Eurydice at Euston?: Walter Benjamin and Marc Augé Go Underground

    Directory of Open Access Journals (Sweden)

    Graeme Gilloch

    2014-01-01

    Full Text Available Taking as its point of departure Walter Benjamin’s repeatedly unsuccessful attempt to give spatial form to his past, this paper suggests that it is perhaps the contemporary French anthropologist, Marc Augé, who provides the most appropriate envisioning of a ‘map of memories’ in his brief writings on the Parisian métro system. For Augé, the labyrinthine subway network constitutes nothing less than a ‘memory machine’ in which lines and station names serve as mnemonics, recalling long-forgotten childhood encounters and experiences. Mirroring the cityscape above, places themselves unexplored, unknown, the serried toponyms of the métro become an incantation summoning forth the shades of the past. As Augé points out, those stations that provide opportunities to change lines are felicitously termed ‘correspondences’, a Baudelairean term that fascinated Benjamin and informed his key historiographical notion of the ‘dialectical image,’ the intersection and mutual illumination of past and present moments. For me, Augé’s highly suggestive reflections bring to mind my own memories of a London childhood around 1970. Looking at the London underground map today, I cannot but see the sites of many past meetings and partings, dots connected by lines forming complex figures, constellations of memory.

    Full Text Available Lack of insight into Greek antiquity, more specifically the nature of classical tragedy and mythology, could be one reason for the negative reception of Benjamin Britten’s last opera Death in Venice. In the first place, this article considers Britten’s opera based on Thomas Mann’s novella as a manifestation of classical tragedy. Secondly, it is shown how mythological characters in Mann’s novella represent abstract ideas2 in Britten’s opera, thereby enhancing the dramatic impact of the opera considerably. On the one hand it is shown how the artist’s inner conflict manifests itself in a dialectic relationship between discipline and inspirat ion in Plato’s Phaedrus dialogue that forms the basis of Aschenbach’s monologue at the end of the opera. The conflict between Aschenbach’s rational consciousness and his irrational subconscious, on the other hand, is depicted by means of mythological figures, Apollo and Dionysus. Two focal points in the opera, namely the Games of Apollo at the end of Act 1 and the nightmare scene which forms the climax of the opera in Act 2, are used to illustrate the musical manifestation of this conflict.

    We develop a general approach to the description of dispersive shock waves (DSWs) for a class of nonlinear wave equations with a nonlocal Benjamin-Ono type dispersion term involving the Hilbert transform. Integrability of the governing equation is not a pre-requisite for the application of this method which represents a modification of the DSW fitting method previously developed for dispersive-hydrodynamic systems of Korteweg-de Vries (KdV) type (i.e. reducible to the KdV equation in the weakly nonlinear, long wave, unidirectional approximation). The developed method is applied to the Calogero-Sutherland dispersive hydrodynamics for which the classification of all solution types arising from the Riemann step problem is constructed and the key physical parameters (DSW edge speeds, lead soliton amplitude, intermediate shelf level) of all but one solution type are obtained in terms of the initial step data. The analytical results are shown to be in excellent agreement with results of direct numerical simulations.

  4. A major seasonal phytoplankton bloom in the Madagascar Basin

    2001-11-01

    A hitherto-unnoticed phytoplankton bloom, of dimension 3000×1500 km, occupies the Madagascar Basin in late austral summer, being a prominent feature in SeaWiFS images. A first-order interpretation of the bloom mechanism invokes the seasonal deepening of the mixed layer within a strong mesoscale eddy-field and the consequent entrainment of nutrients into the photic zone. Features of the bloom correspond closely and appropriately with features of the eddy-field as observed by TOPEX-POSEIDON sea level anomalies. The bloom failed to develop in 1998, the second year of a two-year ENSO episode, when anomalously weak Southeast Trades will have failed to deepen the mixed layer as in other years.

    2014-08-04

    Seawater reverse osmosis (SWRO) desalination technology has been rapidly growing in terms of installed capacity and global application over the last decade. An emerging threat to SWRO application is the seasonal proliferation of microscopic algae in seawater known as algal blooms. Such blooms have caused operational problems in SWRO plants due to clogging and poor effluent quality of the pre-treatment system which eventually forced the shutdown of various desalination plants to avoid irreversible fouling of downstream SWRO membranes. This article summarizes the current state of SWRO technology and the emerging threat of algal blooms to its application. It also highlights the importance of studying the algal bloom phenomena in the perspective of seawater desalination, so proper mitigation and preventive strategies can be developed in the near future. © 2014 © 2014 Balaban Desalination Publications.

    Operation of JET and TFTR at high auxiliary heating power has resulted in the occurrence of phenomena called carbon blooms. The carbon bloom is characterized by a rapid increases in the emission of carbon spectral lines, the Z eff , the radiated power, and the plasma density. There is also a concurrent decrease in the neutron emission rate, stored energy, and plasma pressure. On both machines the source of the carbon is observed to be at localized (both toroidally and polidally) hot spots on either the divertor plates or limiters. The localized hot spots are due to one or more of the following: disruption damage spots, misalignment of tiles, and/or exposed edges of tiles. The occurrence of carbon blooms limits the performance of the highest input power plasmas on both machines. This paper reviews the carbon bloom phenomenon as it occurs on both JET and TFTR. (orig.)

  11. Eddy-driven stratification initiates North Atlantic spring phytoplankton blooms.

    Science.gov (United States)

    Mahadevan, Amala; D'Asaro, Eric; Lee, Craig; Perry, Mary Jane

    2012-07-06

    Springtime phytoplankton blooms photosynthetically fix carbon and export it from the surface ocean at globally important rates. These blooms are triggered by increased light exposure of the phytoplankton due to both seasonal light increase and the development of a near-surface vertical density gradient (stratification) that inhibits vertical mixing of the phytoplankton. Classically and in current climate models, that stratification is ascribed to a springtime warming of the sea surface. Here, using observations from the subpolar North Atlantic and a three-dimensional biophysical model, we show that the initial stratification and resulting bloom are instead caused by eddy-driven slumping of the basin-scale north-south density gradient, resulting in a patchy bloom beginning 20 to 30 days earlier than would occur by warming.

  12. The paradox of algal blooms in oligotrophic waters

    Nutrient inputs to streams and lakes, primarily from anthropogenic sources, lead to eutrophic conditions that favor algal blooms with undesirable consequences. In contrast, low nutrient or oligotrophic waters rarely support algal blooms; such ecosystems are typically lower in productivity. Since the mid-1980’s however, the diatom Didymosphenia geminata has dramatically expanded its range colonizing oligotrophic rivers worldwide with blooms appearing as thick benthic mats. This recent global occurrence of Didymosphenia geminata blooms in temperate rivers has been perplexing in its pace of spread and the paradoxical nature of the nuisance growths. The blooms occur primarily in oligotrophic flowing waters, where phosphorus (P) availability often limits primary production. We present a biogeochemical process by which D. geminata mats adsorb both P and iron (Fe) from flowing waters and make P available for cellular uptake. The adsorbed P becomes bioavailable through biogeochemical processes that occur within the mat. The biogeochemical processes observed here while well accepted in benthic systems are novel for algal blooms in lotic habits. Enzymatic and bacterial processes such as Fe and sulfate reduction can release the adsorbed P and increase its bioavailability, creating a positive feedback between total stalk biomass and nutrient availability. Stalk affinity for Fe, Fe-P biogeochemistry, and interaction between watershed processes and climatic setting explain the paradoxical blooms, and the recent global spread of this invasive aquatic species. At a broader scale the study also implies that such algal blooms in oligotrophic environments can fundamentally alter the retention and longitudinal transfer of important nutrients such as P in streams and rivers.

    The increasing occurrence of algal blooms and their negative ecological impacts have led to intensified monitoring activities. This needs the proper identification of the most responsible factor/factors for the bloom formation. However, in natural systems, algal blooms result from a combination of factors and from observation it is difficult to identify the most important one. In the present paper, using a mathematical model we compare the effects of three human induced factors (fertilizer input in agricultural field, eutrophication due to other sources than fertilizers, and overfishing) on the bloom dynamics and DO level. By applying a sophisticated sensitivity analysis technique, we found that the increasing use of fertilizers in agricultural field causes more rapid algal growth and decreases DO level much faster than eutrophication from other sources and overfishing. We also look at the mechanisms how fertilizer input rate affects the algal bloom dynamics and DO level. The model can be helpful for the policy makers in determining the influential factors responsible for the bloom formation.

Thus, they affect the professionals’ decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italians, 30 Chileans, questioned on this topic. Our findings are consistent with original research and suggest that some participants do not know how to correctly interpret p values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy.

    Science.gov (United States)

    Cyanobacterial harmful algal blooms (cyanoHABs) cause extensive problems in lakes worldwide, including human and ecological health risks, anoxia and fish kills, and taste and odor problems. CyanoHABs are a particular concern because of their dense biomass and the risk of exposure to toxins in both recreational waters and drinking source waters. Successful cyanoHAB assessment by satellites may provide a first-line of defense indicator for human and ecological health protection. In this study, assessment methods were developed to determine the utility of satellite technology for detecting cyanoHAB occurrence frequency at locations of potential management interest. The European Space Agency's MEdium Resolution Imaging Spectrometer (MERIS) was evaluated to prepare for the equivalent Sentinel-3 Ocean and Land Colour Imager (OLCI) launched in 2016. Based on the 2012 National Lakes Assessment site evaluation guidelines and National Hydrography Dataset, there were 275,897 lakes and reservoirs greater than 1 hectare in the 48 U.S. states. Results from this evaluation show that 5.6 % of waterbodies were resolvable by satellites with 300 m single pixel resolution and 0.7 % of waterbodies were resolvable when a 3x3 pixel array was applied based on minimum Euclidian distance from shore. Satellite data was also spatially joined to US public water surface intake (PWSI) locations, where single pixel resolution resolved 57% of PWSI and a 3x3 pixel array resolved 33% of

Motivation for the study: It is not known how students previously educated in a pathogenic paradigm experience the exposure to positive psychology, and resultant paradigm shift, as part of their professional training. Research design, approach and method: A qualitative research design was implemented. Data consisted of written documents submitted by the participants and was analyzed by means of thematic analysis. Main findings: Integrating positive psychology in the professional training curriculum was valuable and enriching on both a professional and personal level. The participants reported an experience of positive emotions and increased sense of self-understanding and psychological well-being. Professionally they experienced a sense of increased self-efficacy. Practical/managerial implications: Positive psychology should be considered as part of the basic training of psychologists since it may enhance the development of trainee psychologists’ professional self, enhance aspects of psychological well-being as well as prevent stress and burnout. Contribution/value-add: This is the first South African study to explore the impact of including positive psychology principles and interventions in professional training.

    2005-05-01

    Advances in the biomedical and the behavioral sciences have paved the way for the integration of medical practice towards the biopsychosocial approach. Therefore, dealing with health and illness overtakes looking for the presence or absence of the disease and infirmity (the biomedical paradigm) to the biopsychosocial paradigm in which health means a state of complete physical, psychological and social well-being. Psychology as a behavioral health discipline is the key to the biopsychosocial practice, and plays a major role in understanding the concept of health and illness. The clinical role of psychologists as health providers is diverse with the varying areas of care giving (primary, secondary and tertiary care) and a variety of subspecialties. Overall, psychologists assess, diagnose, and treat the psychological problems and the behavioral dysfunctions resulting from, or related to physical and mental health. In addition, they play a major role in the promotion of healthy behavior, preventing diseases and improving patients' quality of life. They perform their clinical roles according to rigorous ethical principles and code of conduct. This article describes and discusses the significant role of clinical health psychology in the provision of health care, following a biopsychosocial perspective of health and illness. Professional and educational issues have also been discussed.

    This study examined whether specific types of positive and negative emotional words used in the autobiographies of well-known deceased psychologists were associated with longevity. For each of the 88 psychologists, the percent of emotional words used in writing was calculated and categorized by valence (positive or negative) and arousal (activated [e.g., lively, anxious] or not activated [e.g., calm, drowsy]) based on existing emotion scales and models of emotion categorization. After controlling for sex, year of publication, health (based on disclosed illness in autobiography), native language, and year of birth, the use of more activated positive emotional words (e.g., lively, vigorous, attentive, humorous) was associated with increased longevity. Negative terms (e.g., angry, afraid, drowsy, sluggish) and unactivated positive terms (e.g., peaceful, calm) were not related to longevity. The association of activated positive emotions with longevity was also independent of words indicative of social integration, optimism, and the other affect/activation categories. Results indicate that in writing, not every type of emotion correlates with longevity and that there may be value to considering different categories beyond emotional valence in health relevant outcomes.

  7. Benjamin Cohen on global political order: when Keynes meets realism - and beyond

    Directory of Open Access Journals (Sweden)

    Stefano Guzzini

    2015-12-01

    Full Text Available Abstract This article analyses the trajectory of Benjamin J. Cohen's work by focusing on his ongoing concern with the nature and governance of world order. It does so by playing out his debt to realism and to Keynesianism. In a first moment, Cohen criticises the economic determinism of dependency scholarship, while turning to political realism, and then to possible Keynesian co-operation under anarchy: agents have the power to affect positive change. Later, Cohen the disillusioned Keynesian, watching how the possible reform of financial markets is marginalised by politicians and academics alike, shifts his analysis to more structural aspects of governance or rule that affect actors' preferences. I draw two conclusions. First, in this shift towards theorising the global political order away from steering capacity towards impersonal rule and bias, Cohen also questions the very setup of the theories with which we deal with that world - only to see that this very inspiration of original IPE is abandoned in the course of the ongoing 'professionalisation' of IPE as practised in the United States. Second, his analysis seems to incorporate a warning. The underlying grand question is nothing less than the bargain between capitalism and liberal democracy as we know it, since the present system undermines equality before the law - money trumps equal political rights - and undermines democratic accountability. One of the main achievements of the post-war Keynesian turn was the reappropriation of political space from anti-democratic forces. Therefore, the decline of Keynesianism could provoke a Polanyian nightmare in which the 'double movement' by which the laissez-faire is answered by moves to protect society does not strengthen democracies, as in earlier times of 'embedded liberalism', but undermines them instead.

    Phytoplankton blooms are predictable features of marine and freshwater habitats. Despite a good knowledge base of the environmental factors controlling blooms, complex interactions between the bacterial and archaeal communities and phytoplankton bloom taxa are only now emerging. Here, the current research on bacterial community's structural and functional response to phytoplankton blooms is reviewed and discussed and further research is proposed. More attention should be paid on structure and function of autotrophic bacteria and archaea during phytoplankton blooms. A multiomics integration approach is needed to investigate bacterial and archaeal communities' diversity, metabolic diversity, and biogeochemical functions of microbial interactions during phytoplankton blooms.

  9. Harmful Freshwater Algal Blooms, With an Emphasis on Cyanobacteria

    Hans W. Paerl

    2001-01-01

    Full Text Available Suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Phytoplankton productivity is reliant on adequate nutrient supplies; however, increasing rates of nutrient supply, much of it manmade, fuels accelerating primary production or eutrophication. An obvious and problematic symptom of eutrophication is rapid growth and accumulations of phytoplankton, leading to discoloration of affected waters. These events are termed blooms. Blooms are a prime agent of water quality deterioration, including foul odors and tastes, deoxygenation of bottom waters (hypoxia and anoxia, toxicity, fish kills, and food web alterations. Toxins produced by blooms can adversely affect animal (including human health in waters used for recreational and drinking purposes. Numerous freshwater genera within the diverse phyla comprising the phytoplankton are capable of forming blooms; however, the blue-green algae (or cyanobacteria are the most notorious bloom formers. This is especially true for harmful toxic, surface-dwelling, scum-forming genera (e.g., Anabaena, Aphanizomenon, Nodularia, Microcystis and some subsurface bloom-formers (Cylindrospermopsis, Oscillatoria that are adept at exploiting nutrient-enriched conditions. They thrive in highly productive waters by being able to rapidly migrate between radiance-rich surface waters and nutrient-rich bottom waters. Furthermore, many harmful species are tolerant of extreme environmental conditions, including very high light levels, high temperatures, various degrees of desiccation, and periodic nutrient deprivation. Some of the most noxious cyanobacterial bloom genera (e.g., Anabaena, Aphanizomenon, Cylindrospermopsis, Nodularia are capable of fixing atmospheric nitrogen (N2, enabling them to periodically dominate under nitrogen-limited conditions. Cyanobacteria produce a range of organic compounds, including those that are toxic to higher-ranked consumers, from

  11. Optical detection of Prorocentrum donghaiense blooms based on multispectral reflectance

    Prorocentrum donghaiense is one of the most common red tide causative dinoflagellates in the Changjiang (Yangtze) River Estuary and the adjacent area of the East China Sea. It causes large-scale blooms in late spring and early summer that lead to widespread ecologic and economic damage. A means for distinguish-ing dinoflagellate blooms from diatom (Skeletonema costatum) blooms is desired. On the basis of measure-ments of remote sensing reflectance [Rrs(λ)] and inherent optical parameters, the potential of using a mul-tispectral approach is assessed for discriminating the algal blooms due to P. donghaiense from those due to S. costatum. The behavior of two reflectance ratios [R1 =Rrs(560)/Rrs(532) and R2 =Rrs(708)/Rrs(665)], suggests that differentiation of P. donghaiense blooms from diatom bloom types is possible from the current band setup of ocean color sensors. It is found that there are two reflectance ratio regimes that indicate a bloom is dominated by P. donghaiense: (1) R1 >1.55 and R2 1.75 and R2 ?1.0. Various sensitivity analyses are conducted to investigate the effects of the variation in varying levels of chlorophyll concentration and colored dissolved organic matter (CDOM) as well as changes in the backscattering ratio (bbp/bp) on the efficacy of this multispectral approach. Results indicate that the intensity and inherent op-tical properties of the algal species explain much of the behavior of the two ratios. Although backscattering influences the amplitude of Rrs(λ), especially in the 530 and 560 nm bands, the discrimination between P. donghaiense and diatoms is not significantly affected by the variation of bbp/bp. Since a CDOM(440) in coastal areas of the ECS is typically lower than 1.0 m−1 in most situations, the presence of CDOM does not interfere with this discrimination, even as SCDOM varies from 0.01 to 0.026 nm−1. Despite all of these effects, the dis-crimination of P. donghaiense blooms from diatom blooms based on multispectral

    Bloom's taxonomy was adopted to create a subject-specific scoring tool for histology multiple-choice questions (MCQs). This Bloom's Taxonomy Histology Tool (BTHT) was used to analyze teacher- and student-generated quiz and examination questions from a graduate level histology course. Multiple-choice questions using histological images were generally assigned a higher BTHT level than simple text questions. The type of microscopy technique (light or electron microscopy) used for these image-based questions did not result in any significant differences in their Bloom's taxonomy scores. The BTHT levels for teacher-generated MCQs correlated positively with higher discrimination indices and inversely with the percent of students answering these questions correctly (difficulty index), suggesting that higher-level Bloom's taxonomy questions differentiate well between higher- and lower-performing students. When examining BTHT scores for MCQs that were written by students in a Multiple-Choice Item Development Assignment (MCIDA) there was no significant correlation between these scores and the students' ability to answer teacher-generated MCQs. This suggests that the ability to answer histology MCQs relies on a different skill set than the aptitude to construct higher-level Bloom's taxonomy questions. However, students significantly improved their average BTHT scores from the midterm to the final MCIDA task, which indicates that practice, experience and feedback increased their MCQ writing proficiency.

  13. Detection of surface algal blooms using the newly developed algorithm surface algal bloom index (SABI)

    Science.gov (United States)

    Alawadi, Fahad

    2010-10-01

    Quantifying ocean colour properties has evolved over the past two decades from being able to merely detect their biological activity to the ability to estimate chlorophyll concentration using optical satellite sensors like MODIS and MERIS. The production of chlorophyll spatial distribution maps is a good indicator of plankton biomass (primary production) and is useful for the tracing of oceanographic currents, jets and blooms, including harmful algal blooms (HABs). Depending on the type of HABs involved and the environmental conditions, if their concentration rises above a critical threshold, it can impact the flora and fauna of the aquatic habitat through the introduction of the so called "red tide" phenomenon. The estimation of chlorophyll concentration is derived from quantifying the spectral relationship between the blue and the green bands reflected from the water column. This spectral relationship is employed in the standard ocean colour chlorophyll-a (Chlor-a) product, but is incapable of detecting certain macro-algal species that float near to or at the water surface in the form of dense filaments or mats. The ability to accurately identify algal formations that sometimes appear as oil spill look-alikes in satellite imagery, contributes towards the reduction of false-positive incidents arising from oil spill monitoring operations. Such algal formations that occur in relatively high concentrations may experience, as in land vegetation, what is known as the "red-edge" effect. This phenomena occurs at the highest reflectance slope between the maximum absorption in the red due to the surrounding ocean water and the maximum reflectance in the infra-red due to the photosynthetic pigments present in the surface algae. A new algorithm termed the surface algal bloom index (SABI), has been proposed to delineate the spatial distributions of floating micro-algal species like for example cyanobacteria or exposed inter-tidal vegetation like seagrass. This algorithm was

    2014-02-01

    Full Text Available In 1816, after close examination, the Spanish Inquisition forbade Benjamin Constant’s Principes de Politique, the most representative work of liberal ideology of its day. A careful study of the official indictment shows that in the early 19th c. the concepts of natural law and of the general will introduced by the Enlightenment were still being countered with the same arguments which had been used in the preceding century. Nonetheless, the consequences for Spain of the French Revolution would force the Inquisition to face the challenges posed by liberalism in Europe.

    Full Text Available Este artigo estuda as concepções de estética e experiência de Clifford Geertz e Walter Benjamin como possibilidades argumentativas e metodológicas para pensar a realidade e suas formas estéticas. Utiliza-se para isso as discussões metodológicas de Geertz, especialmente a respeito do lugar da estética e de sua relação com os demais âmbitos do humano, que encetaram uma nova forma de concebê-los para a etnografia e antropologia de modo geral, e os estudos de Benjamin a respeito da estética como expressão fisionômica de uma época, de determinada realidade, especialmente os que se referem sobre a modernidade. Constata-se essa possibilidade a partir da observação de que a estética e a experiência, nos autores, são tomadas como dimensões da realidade que se relacionam, não de modo mecânico, e sim como âmbitos que atravessam a realidade, os artefatos estéticos, os discursos, e esses assim devem ser observados.This article study the conceptions of aesthetics and experience of Clifford Geertz and Walter Benjamin as argumentative and methodological possibilities for thinking reality and its aesthetic forms. Uses for this Geertz's methodological discussions, especially regarding the place of aesthetics and its relation to other spheres of the human, which has embarked on a new way of conceiving them to ethnography and anthropology in general, and studies Benjamin about the aesthetics and physiognomical expression of an era, a certain reality, especially those concerning about modernity. There is that possibility from the observation that the aesthetics and experience, in the authors, are taken as the dimensions of reality are related, not mechanically, but as areas that cross the reality, the aesthetic artifacts, the speeches, and so these must be observed.

    2013-11-01

    Full Text Available This paper aims to critically review the role of a psychodynamic psychologist integrated in a community outpatient clinic of a Psychiatric Department. It describes the characteristics of a psychodynamic intervention that is complementary to the psychiatric approach while sharing a common goal –the suffering patient – and enhancing the knowledge and understanding of several domains like psychopathology, diagnosis, treatment, rehabilitation and integration. Furthermore it describes how the use of Psychological Assessment led to the formulation of specific individual psychotherapies, spanning 14 years of clinical practice. The paper concludes with some considerations regarding the integration of Psychodynamic Psychology in a multidisciplinary mental health team, addressing issues such as the boundaries between technical characteristics, the appropriateness of language to other disciplines and psychodynamic implications of the different features of this clinical setting.

    2015-01-01

    A central part of providing evidence-based practice is appropriate cultural competence to facilitate psychological assessment and intervention with diverse clients. At a minimum, cultural competence with lesbian, gay, bisexual, and transgender (LGBT) people involves adequate scientific and supervised practical training, with increasing depth and complexity across training levels. In order to further this goal, we offer 28 recommendations of minimum standards moving toward ideal training for LGBT-specific cultural competence. We review and synthesize the relevant literature to achieve and assess competence across the various levels of training (doctoral, internship, post-doctoral, and beyond) in order to guide the field towards best practices. These recommendations are aligned with educational and practice guidelines set forth by the field and informed by other allied professions in order to provide a roadmap for programs, faculty, and trainees in improving the training of psychologists to work with LGBT individuals.

    2014-10-01

    Research purpose: The aim of this study was to review the role of I-O psychologists as counsellors and to ascertain whether these practitioners are effectively prepared for this purpose. Motivation for the study: I-O psychologists are mainly concerned with the deep-rooted problems individuals experience in the workplace, and they therefore need appropriate counselling skills. However, it is not clear whether graduates in this discipline receive adequate training for this role. Research design, approach and method: A qualitative research design with convenience and snowball sampling of 22 participants was utilised. Participants were practising I-O psychologists across Gauteng and North West (South Africa. Semi-structured in-depth interviews were used to gather data, which were transcribed verbatim and analysed using content analysis. Main findings: Participants were familiar with the meaning of counselling and confirmed that they are faced with a range of counselling situations requiring a unique set of skills and competencies. Based on these findings, participants made recommendations for the future training of I-O psychologists and recommended that counselling be included in the scope of practice of I-O psychologists. Practical/managerial implications: The role of the I-O psychologist requires training in short-term therapeutic techniques and counselling in tertiary education. Contribution/value-add: The study clarifies the role of the I-O psychologist as a counsellor that will ensure that I-O psychologists can be trained more effectively for this role.

    2017-09-01

    Full Text Available The paper considers the possibility of using the principles of gradual development of intellectual activity in the training experts of developmental psychology. The issue of the managed development of professional work components is being raised. A possible way of working is discussed analysing the features of child actual development aimed at discovering the reasons for the learning difficulties, which served as an excuse for the parents to seek psychological assistance. The method of analysis becomes an important competence of a consulting psychologist against the background of a high variety of forms of mental development. Development of readymade algorithms for solving a problem situation, covering all their diversity seems next to impossible. In this regard, there is a need to prepare students for an independent analysis of a specific life situation. It is the ability to this kind of analysis that ensures the expert’s preparedness to develop recommendations that contribute to harmonizing the child’s development. Elaboration of this competence implies the integration of knowledge and skills acquired in various training courses. This possibility is provided by shaping the student’s orientation in the learned action taking into account its level structure. Semantically speaking, orientation allows one to recover the logic of the child’s examination and child development according to the goal set. The orientation is based on the mechanisms and conditions of mental development. The choice of adequate diagnostic tools becomes an independent task of the analysis that requires understanding of the available techniques and diagnostic tools. Summing up, the operational level of orientation provides competent use of the means chosen during diagnostic examination. Taking into account the orientation level of the developed activity makes it possible to integrate the knowledge and skills gained in the process of training into psychologist expert

In the present paper, using a mathematical model we compare the effects of three human induced factors (fertilizer input in agricultural field, eutrophication due to other sources than fertilizers, and overfishing......) on the bloom dynamics and DO level. By applying a sophisticated sensitivity analysis technique, we found that the increasing use of fertilizers in agricultural field causes more rapid algal growth and decreases DO level much faster than eutrophication from other sources and overfishing. We also look...... at the mechanisms how fertilizer input rate affects the algal bloom dynamics and DO level.

    The influence of hydrodynamics on phytoplankton bloom occurrence/formation has not been adequately reported. Here, we document diurnal observations in the tropical Bay of Bengal's mid-western shelf region which reveal microphytoplankton cell density maxima in association with neap tide many times more than what could be accounted for by solar insolation and nutrient levels. When in summer, phytoplankton cells were abundant and the cell density of Guinardia delicatula reached critical value by tide caused zonation, aggregation happened to an intense bloom. Mucilaginous exudates from the alga due to heat and silicate stress likely promoted and stable water column and weak winds left undisturbed, the transient bloom. The phytoplankton aggregates have implication as food resource in the benthic region implying higher fishery potential, in carbon dioxide sequestration (carbon burial) and in efforts towards improving remote sensing algorithms for chlorophyll in the coastal region.

    Cyanobacteria form spectacular mass occurrences almost annually in the Baltic Sea. These harmful algal blooms are the most visible consequences of marine eutrophication, driven by a surplus of nutrients from anthropogenic sources and internal processes of the ecosystem. We present a novel Cyanobacterial Bloom Indicator (CyaBI) targeted for the ecosystem assessment of eutrophication in marine areas. The method measures the current cyanobacterial bloom situation (an average condition of recent 5 years) and compares this to the estimated target level for 'good environmental status' (GES). The current status is derived with an index combining indicative bloom event variables. As such we used seasonal information from the duration, volume and severity of algal blooms derived from earth observation (EO) data. The target level for GES was set by using a remote sensing based data set named Fraction with Cyanobacterial Accumulations (FCA; Kahru & Elmgren, 2014) covering years 1979-2014. Here a shift-detection algorithm for time series was applied to detect time-periods in the FCA data where the level of blooms remained low several consecutive years. The average conditions from these time periods were transformed into respective CyaBI target values to represent target level for GES. The indicator is shown to pass the three critical factors set for marine indicator development, namely it measures the current status accurately, the target setting can be scientifically proven and it can be connected to the ecosystem management goal. An advantage of the CyaBI method is that it's not restricted to the data used in the development work, but can be complemented, or fully applied, by using different types of data sources providing information on cyanobacterial accumulations.

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available In his Denkbilder, the Jewish philosopher and homme de lettre Walter Benjamin describes scenes from European metropolises. He offers a glance at quite heterogeneous and freely chosen life styles of the turbulent nineteen-twenties to sketch a possible future for Europe. Today’s reader of the Denkbilder can hardly suppress the memory of a political and personal crisis, namely that of Benjamin’s flight across the Pyrenees, which ended in the Spanish harbour town Portbou. In the poem Der Wanderer, the writer Johannes Bobrowski, a resident of East Berlin, captures the life of a wanderer who depends on the hospitality of others, because he is either persecuted or his freely chosen lifestyle requires him to roam about. For both authors, travelling becomes a substitute for “Heimat” and also a way of life that represents the future of Europe. This forward-looking attitude is based on the experience of cataclysmic events that have been memorably expressed in highly literate apocalyptic images. The writer and graphic designer Christoph Meckel emphasizes how life rises out of ruins only to return to them, by embedding the lyrical process in Eastern European villages, thereby creating a country for which Bobrowski had chosen the mythological name “Sarmatia”, which stands for a messianic utopian vision shared by Benjamin and others.

    Directory of Open Access Journals (Sweden)

    Nathaniel Smith Kogan

    2016-08-01

    Full Text Available This article re-evaluates traditional interpretations and presentations of the (in-famous eighteenth century Quaker abolitionist, Benjamin Lay, by arguing that his physical disability provided the foundation for his advocacy to eliminate slaveholding amongst his fellow Friends. The article will first establish the historical context Benjamin Lay's life and transatlantic travels to explain the roots of his abolitionist advocacy. Then, this article will analyze Lay's radical abolitionism both within the context of eighteenth-century Quaker antislavery and through the lens of disability history. This methodological approach will reveal that Lay displayed a clear awareness of his non-conforming body and the ways that its marginalizing effects empowered him to radically challenge the Quaker slaveholding establishment. The article will then analyze Lay's All Slave-Keepers, Apostates and argue that Lay rhetorically constructed his own disability in this text through both a religious lens and through the emerging Enlightenment concept of human aberrance and hierarchy. Finally, the article will conclude by analyzing some of the earliest visual representations of Lay's strange body and contend that the context in which they were commissioned and circulated forged a positive connection between Lay's disability and his abolitionist accomplishments.

    Full Text Available O artigo estabelece um diálogo entre as teorias de Carl Schmitt, Walter Benjamin e Giorgio Agamben, transpondo-as para a realidade social brasileira. A naturalização da desigualdade constitui marca cruel de nossa sociedade, e a filosofia do direito contribui para uma abordagem jurídica que leva em conta as disparidades sociais. Far-se-á, primeiramente, uma análise do estado de exceção à luz das obras de Benjamin e Agamben. Posteriormente, com Schmitt, a questão da exceção será analisada em conjunto com a decisão política, demonstrando a ligação intrínseca entre direito e política e o reflexo disto no agravamento das desigualdades sociais. Será estabelecida a diferença entre os conceitos de “inimigo”, de Schmitt, e homo sacer, de Agamben, na instauração do estado de exceção e como o conceito de “inimigo” foi desvirtuado com a construção da Teoria do Direito Penal do Inimigo.

    Highlights: • Complex SAR imagery enables better recognition of macroalgae patches. • Combination of different information in SAR matrix forms new index factors. • Proposed index factors contribute to unsupervised recognition of macroalgae. -- Abstract: Increased frequency and enhanced damage to the marine environment and to human society caused by green macroalgae blooms demand improved high-resolution early detection methods. Conventional satellite remote sensing methods via spectra radiometers do not work in cloud-covered areas, and therefore cannot meet these demands for operational applications. We present a methodology for green macroalgae bloom detection based on RADARSAT-2 synthetic aperture radar (SAR) images. Green macroalgae patches exhibit different polarimetric characteristics compared to the open ocean surface, in both the amplitude and phase domains of SAR-measured complex radar backscatter returns. In this study, new index factors are defined which have opposite signs in green macroalgae-covered areas, compared to the open water surface. These index factors enable unsupervised detection from SAR images, providing a high-resolution new tool for detection of green macroalgae blooms, which can potentially contribute to a better understanding of the mechanisms related to outbreaks of green macroalgae blooms in coastal areas throughout the world ocean

  18. Fungal parasitism: life cycle, dynamics and impact on cyanobacterial blooms.

    Mélanie Gerphagnon

    Full Text Available Many species of phytoplankton are susceptible to parasitism by fungi from the phylum Chytridiomycota (i.e. chytrids. However, few studies have reported the effects of fungal parasites on filamentous cyanobacterial blooms. To investigate the missing components of bloom ecosystems, we examined an entire field bloom of the cyanobacterium Anabaena macrospora for evidence of chytrid infection in a productive freshwater lake, using a high resolution sampling strategy. A. macrospora was infected by two species of the genus Rhizosiphon which have similar life cycles but differed in their infective regimes depending on the cellular niches offered by their host. R. crassum infected both vegetative cells and akinetes while R. akinetum infected only akinetes. A tentative reconstruction of the developmental stages suggested that the life cycle of R. crassum was completed in about 3 days. The infection affected 6% of total cells (and 4% of akinètes, spread over a maximum of 17% of the filaments of cyanobacteria, in which 60% of the cells could be parasitized. Furthermore, chytrids may reduce the length of filaments of Anabaena macrospora significantly by "mechanistic fragmentation" following infection. All these results suggest that chytrid parasitism is one of the driving factors involved in the decline of a cyanobacteria blooms, by direct mortality of parasitized cells and indirectly by the mechanistic fragmentation, which could weaken the resistance of A. macrospora to grazing.

    2014-05-01

    A series of oceanographic surveys on Georges Bank document variability of populations of the toxic dinoflagellate Alexandrium fundyense on time scales ranging from synoptic to seasonal to interannual. Blooms of A. fundyense on Georges Bank can reach concentrations on the order of 10 4 cells l -1 , and are generally bank-wide in extent. Georges Bank populations of A. fundyense appear to be quasi-independent of those in the adjacent coastal Gulf of Maine, insofar as they occupy a hydrographic niche that is colder and saltier than their coastal counterparts. In contrast to coastal populations that rely on abundant resting cysts for bloom initiation, very few cysts are present in the sediments on Georges Bank. Bloom dynamics must therefore be largely controlled by the balance between growth and mortality processes, which are at present largely unknown for this population. Based on correlations between cell abundance and nutrient distributions, ammonium appears to be an important source of nitrogen for A. fundyense blooms on Georges Bank.

    Full Text Available Toxic cyanobacterial blooms are a major issue in freshwater systems in many countries. The potentially toxic species and their ecological causes are likely to be different in tropical zones from those in temperate water bodies; however, studies on tropical toxic cyanobacterial blooms are sporadic and currently there is no global synthesis. In this review, we examined published information on tropical cyanobacterial bloom occurrence and toxin production to investigate patterns in their growth and distribution. Microcystis was the most frequently occurring bloom genus throughout tropical Asia, Africa and Central America, while Cylindrospermopsis and Anabaena blooms occurred in various locations in tropical Australia, America and Africa. Microcystis blooms were more prevalent during the wet season while Cylindrospermopsis blooms were more prevalent during the dry period. Microcystin was the most encountered toxin throughout the tropics. A meta-analysis of tropical cyanobacterial blooms showed that Microcystis blooms were more associated with higher total nitrogen concentrations, while Cylindrospermopsis blooms were more associated with higher maximum temperatures. Meta-analysis also showed a positive linear relationship between levels of microcystin and N:P (nitrate:phosphate ratio. Tropical African Microcystis blooms were found to have the lowest microcystin levels in relation to biomass and N:P (nitrate:phosphate compared to tropical Asian, Australian and American blooms. There was also no significant correlation between microcystin concentration and cell concentration for tropical African blooms as opposed to tropical Asian and American blooms. Our review illustrates that some cyanobacteria and toxins are more prevalent in tropical areas. While some tropical countries have considerable information regarding toxic blooms, others have few or no reported studies.

    Full Text Available Orientation: Industrial-organisational (I-O psychologists are often confronted with counselling interventions in the workplace and thus it is vital that they are effectively prepared for their role as workplace counsellors. Research purpose: The aim of this study was to review the role of I-O psychologists as counsellors and to ascertain whether these practitioners are effectively prepared for this purpose. Motivation for the study: I-O psychologists are mainly concerned with the deep-rooted problems individuals experience in the workplace, and they therefore need appropriate counselling skills. However, it is not clear whether graduates in this discipline receive adequate training for this role. Research design, approach and method: A qualitative research design with convenience and snowball sampling of 22 participants was utilised. Participants were practising I-O psychologists across Gauteng and North West (South Africa. Semi-structured in-depth interviews were used to gather data, which were transcribed verbatim and analysed using content analysis. Main findings: Participants were familiar with the meaning of counselling and confirmed that they are faced with a range of counselling situations requiring a unique set of skills and competencies. Based on these findings, participants made recommendations for the future training of I-O psychologists and recommended that counselling be included in the scope of practice of I-O psychologists. Practical/managerial implications: The role of the I-O psychologist requires training in short-term therapeutic techniques and counselling in tertiary education. Contribution/value-add: The study clarifies the role of the I-O psychologist as a counsellor that will ensure that I-O psychologists can be trained more effectively for this role.

    Full Text Available The aim of the research was to determine the state of affairs regarding professional ethics of Slovene psychologists, particularly regarding the implementation of ethical principles and psychologists' and students' knowledge of ethics and procedures in the cases of ethical dilemmas and violations. Two dedicated questionnaires were designed by the authors. 800 Slovene psychologists received the questionnaire and 150 of them responded. There were also 56 psychology students involved in the study. The results show some problematic issues such as: record keeping, exceptions of confidentiality, access to personal data, the content of informed consent, incompetence, copying of literature and diagnostic instruments – even not standardised ones, psychology students as subjects in psychological research, and lack of information on ethical aspects of students' practical work. Psychologists and students reported inadequate knowledge of professional ethics and suggested various kinds of ethical education. Institutions mostly enable psychologists to work within the Code of ethics. There are, however, conflicts regarding access to data and professional autonomy. Psychologists report conflicts between law and ethics, incorrect reports in media and lack of control over professional ethics. In the case of ethical violation psychologists do less than they should. They emphasise the problem of incompetence. The frequency and seriousness of certain violation were estimated. Ways of verifying knowledge, stimulating ethical conduct and taking different measures in the case of violations were suggested. The state of affairs in different working environments of psychologists was also described. Results show that psychologist who have worked in the field for a shorter period answer more frequently contrary to the Code of Ethics. Students' knowledge of ethics is mostly very satisfactory. The study emphasises the ethical aspects of psychological practice in Slovenia. It

    Previous researches reported compelling sea ice phytoplankton bloom in Arctic, while seldom reports studied about Antarctic. Here, lab experiment showed sea ice increased the visible light albedo of the water leaving radiance. Even a new formed sea ice of 10cm thickness increased water leaving radiance up to 4 times of its original bare water. Given that phytoplankton preferred growing and accumulating under the sea ice with thickness of 10cm-1m, our results showed that the changing rate of OC4 estimated [Chl-a] varied from 0.01-0.5mg/m3 to 0.2-0.3mg/m3, if the water covered by 10cm sea ice. Going further, varying thickness of sea ice modulated the changing rate of estimating [Chl-a] non-linearly, thus current routine OC4 model cannot estimate under sea ice [Chl-a] appropriately. Besides, marginal sea ice zone has a large amount of mixture regions containing sea ice, water and snow, where is favorable for phytoplankton. We applied 6S model to estimate the sea ice/snow contamination on sub-pixel water leaving radiance of 4.25km spatial resolution ocean color products. Results showed that sea ice/snow scale effectiveness overestimated [Chl-a] concentration based on routine band ratio OC4 model, which contamination increased with the rising fraction of sea ice/snow within one pixel. Finally, we analyzed the under sea ice bloom in Antarctica based on the [Chl-a] concentration trends during 21 days after sea ice retreating. Regardless of those overestimation caused by sea ice/snow sub scale contamination, we still did not see significant under sea ice blooms in Antarctica in 2012-2017 compared with Arctic. This research found that Southern Ocean is not favorable for under sea ice blooms and the phytoplankton bloom preferred to occur in at least 3 weeks after sea ice retreating.

  12. State of knowledge and concerns on cyanobacterial blooms and cyanotoxins.

    Cyanobacteria are ubiquitous microorganisms considered as important contributors to the formation of Earth's atmosphere and nitrogen fixation. However, they are also frequently associated with toxic blooms. Indeed, the wide range of hepatotoxins, neurotoxins and dermatotoxins synthesized by these bacteria is a growing environmental and public health concern. This paper provides a state of the art on the occurrence and management of harmful cyanobacterial blooms in surface and drinking water, including economic impacts and research needs. Cyanobacterial blooms usually occur according to a combination of environmental factors e.g., nutrient concentration, water temperature, light intensity, salinity, water movement, stagnation and residence time, as well as several other variables. These environmental variables, in turn, have promoted the evolution and biosynthesis of strain-specific, gene-controlled metabolites (cyanotoxins) that are often harmful to aquatic and terrestrial life, including humans. Cyanotoxins are primarily produced intracellularly during the exponential growth phase. Release of toxins into water can occur during cell death or senescence but can also be due to evolutionary-derived or environmentally-mediated circumstances such as allelopathy or relatively sudden nutrient limitation. Consequently, when cyanobacterial blooms occur in drinking water resources, treatment has to remove both cyanobacteria (avoiding cell lysis and subsequent toxin release) and aqueous cyanotoxins previously released. Cells are usually removed with limited lysis by physical processes such as clarification or membrane filtration. However, aqueous toxins are usually removed by both physical retention, through adsorption on activated carbon or reverse osmosis, and chemical oxidation, through ozonation or chlorination. While the efficient oxidation of the more common cyanotoxins (microcystin, cylindrospermopsin, anatoxin and saxitoxin) has been extensively reported, the chemical

    Psychologists become more effective and relevant when they appreciate that many clients hold religious values and commitments. Greater awareness of religion and religious values in the lives of clients may aid clinicians' efforts to provide more accurate assessments and effective treatment plans. The authors use the American Psychological Association's (1992) "Ethical Principles of Psychologists and Code of Conduct" as a framework to examine many of the ethical issues relevant when psychologists work with religious clients. This article also provides suggestions for ways in which clinicians may obtain the skills needed to offer competent assessments and interventions with religiously committed clients.

    Full Text Available This paper proposes a method of short-term prediction of algae bloom based on artificial neural network. Firstly, principal component analysis is applied to water environmental factors in algae bloom raceway ponds to get main factors that influence the formation of algae blooms. Then, a model of short-term dynamic prediction based on neural network is built with the current chlorophyll_a values as input and the chlorophyll_a values in the next moment as output to realize short-term dynamic prediction of algae bloom. Simulation results show that the model can realize short-term prediction of algae bloom effectively.

    Full Text Available Adaptation is the process of transforming one form of art into another one. Many decent films are adapted from great literary work. In the adaptation process, some changes occur in film. It is because film is produced in different way from novel. This study focuses on the transformation of the narrative elements from the short story into the film entitled The Curious Case of Benjamin Button. This study uses the theory of adaptation by Linda Seger to explain the adaptation process from the short story into the film as the sources of data. There are three processes of adaptation: condensing and expanding the material, the process of making the film commercial, and varied changing. The narrative elements theory is also used to explain the structure that builds the literary work.

    We consider the generalised dispersive modified Benjamin-Bona-Mahony equation, which describes an approximation status for long surface wave existed in the non-linear dispersive media. By employing the truncated Painlevé expansion method, we derive its non-local symmetry and Bäcklund transformation. The non-local symmetry is localised by a new variable, which provides the corresponding non-local symmetry group and similarity reductions. Moreover, a direct method can be provided to construct a kind of finite symmetry transformation via the classic Lie point symmetry of the normal prolonged system. Finally, we find that the equation is a consistent Riccati expansion solvable system. With the help of the Jacobi elliptic function, we get its interaction solutions between solitary waves and cnoidal periodic waves.

    2015-01-01

    Phytoplankton blooms are dynamic phenomena of great importance to the functioning of estuarine and coastal ecosystems. We analysed a unique (large) collection of phytoplankton monitoring data covering 86 coastal sites distributed over eight regions in North America and Europe, with the aim of investigating common patterns in the seasonal timing and species composition of the blooms. The spring bloom was the most common seasonal pattern across all regions, typically occurring early (February–March) at lower latitudes and later (April–May) at higher latitudes. Bloom frequency, defined as the probability of unusually high biomass, ranged from 5 to 35% between sites and followed no consistent patterns across gradients of latitude, temperature, salinity, water depth, stratification, tidal amplitude or nutrient concentrations. Blooms were mostly dominated by a single species, typically diatoms (58% of the blooms) and dinoflagellates (19%). Diatom-dominated spring blooms were a common feature in most systems, although dinoflagellate spring blooms were also observed in the Baltic Sea. Blooms dominated by chlorophytes and cyanobacteria were only common in low salinity waters and occurred mostly at higher temperatures. Key bloom species across the eight regions included the diatoms Cerataulina pelagica and Dactyliosolen fragilissimus and dinoflagellates Heterocapsa triquetra and Prorocentrum cordatum. Other frequent bloom-forming taxa were diatom genera Chaetoceros, Coscinodiscus, Skeletonema, and Thalassiosira. Our meta-analysis shows that these 86 estuarine-coastal sites function as diatom-producing systems, the timing of that production varies widely, and that bloom frequency is not associated with environmental factors measured in monitoring programs. We end with a perspective on the limitations of conclusions derived from meta-analyses of phytoplankton time series, and the grand challenges remaining to understand the wide range of bloom patterns and

    After the 9-11 terrorist attacks, U.S. psychologists faced hard choices about what roles, if any, were appropriate for psychologists in the detainee interrogations conducted in settings such as the Bagram Airbase, the Abu Ghraib Prison, and the Guantanamo Bay Detention Camps. The American Psychological Association (APA) sparked intense controversy with its policies and public statements. This article reviews APA decisions, documents, and public statements in this area, in the context of major criticisms and responses to those criticisms. The review focuses on key issues: how the APA created and reported policies in the areas of ethics and national security; transparency; psychologists' professional identities; psychologists' qualifications; ethical-legal conflicts; policies opposing torture; interpretations of avoiding harm; and effective interrogations. It suggests lessons learned, missed opportunities, and questions in need of a fresh approach. © 2011 by Annual Reviews. All rights reserved

    Previous research highlights barriers to clinical psychologists conducting research, but has rarely examined U.K. clinical psychologists. The study investigated U.K. clinical psychologists' self-reported research output and tested part of a theoretical model of factors influencing their intention to conduct research. Questionnaires were mailed to 1,300 U.K. clinical psychologists. Three hundred and seventy-four questionnaires were returned (29% response-rate). This study replicated in a U.K. sample the finding that the modal number of publications was zero, highlighted in a number of U.K. and U.S. studies. Research intention was bimodally distributed, and logistic regression classified 78% of cases successfully. Outcome expectations, perceived behavioral control and normative beliefs mediated between research training environment and intention. Further research should explore how research is negotiated in clinical roles, and this issue should be incorporated into prequalification training. © 2012 Wiley Periodicals, Inc.

    2017-01-01

    Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists' different experiences of burnout in Australia. Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists' natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding 'first order constructs' and then axial code 'second order constructs.' Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients' expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints. Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental shortcomings of working as a solo

    The current study evaluates a depression prevention program for adolescents led by psychologists vs. teachers in comparison to a control. The universal school-based prevention program has shown its efficacy in several studies when implemented by psychologists. The current study compares the effects of the program as implemented by teachers versus that implemented by psychologists under real-life conditions. A total of 646 vocational track 8th grade students from Germany participated either in a universal prevention program, led by teachers (n = 207) or psychologists (n = 213), or a teaching-as-usual control condition (n = 226). The design includes baseline, post-intervention, and follow-up (at 6 and 12 months post-intervention). The cognitive-behavioral program includes 10 sessions held in a regular school setting in same-gender groups and is based on the social information-processing model of social competence. Positive intervention effects were found on the change in girls’ depressive symptoms up to 12 months after program delivery when the program was implemented by psychologists. No such effects were found on boys or when program was delivered by teachers. The prevention program can successfully be implemented for girls by psychologists. Further research is needed for explanations of these effects. PMID:24837667

    Psychologists' roles within academic medicine have expanded well beyond research and scholarship. They are active as providers of patient care, medical education, and clinical supervision. Although the number of psychologists in academic health centers continues to grow, they represent a small portion of total medical school faculties. However, with the movement toward collaborative care models, emphasis on interprofessional teams, and increased emphasis on psychological science topics in medical curricula, psychologists are well-positioned to make further contributions. Another path through which psychologists can further increase their contributions and value within academic health centers is to aspire to leadership roles. This article describes the first author's reflections on her experiences in a two-year, cohort-based, educational leadership development certificate program in academic medicine. The cohort was comprised largely of physicians and basic scientists, and a small number of non-physician participants of which the first author was the only clinical psychologist. The insights gained from this experience provide recommendations for psychologists interested in leadership opportunities in academic medicine.

    The author presented this Presidential Address for Divison 18, Psychologists in Public Service, at the 2012 American Psychological Association Convention in Orlando, Florida. The address challenges public service psychologists to reduce the tobacco disease burden through their roles as researchers, leaders, educators, and practitioners and explains why treating tobacco use disorder is important and relevant for psychologists. The address discusses the prevalence and the resulting mortality and morbidity rates of tobacco use disorder, which call for effective evidence-based interventions that can be integrated by psychologists into other ongoing treatments. Treatment of the underserved populations, including those with serious mental illness and/or substance use disorders, presents many barriers. In addition, education and training for tobacco use disorder in undergraduate and graduate clinical psychology programs present further barriers for psychology trainees. However, progress is being made because of the numerous resources and psychology leaders who are advocates for tobacco use disorder treatment and research. Challenges for the future include increasing awareness of the importance of treatment for tobacco use disorder, finding innovative ways to increase access to comprehensive evidence-based treatment, and acknowledging that psychologists can make a difference in reducing the tobacco use disorder disease burden. Psychologists have an ethical and professional responsibility to treat tobacco use disorder.

    Full Text Available Red tide, one of the harmful algal blooms (HABs is a natural ecological phenomenon and often this event is accompanied by severe impacts on coastal resources, local economies, and public health. The occurrence of red tides has become more frequent in Omani waters in recent years. Some of them caused fish kill, damaged fishery resources and mariculture, threatened the marine environment and the osmosis membranes of desalination plants. However, a number of them have been harmless. The most common dinoflagellate Noctiluca scintillans is associated with the red tide events in Omani waters. Toxic species like Karenia selliformis, Prorocentrum arabianum, and Trichodesmium erythraeum have also been reported recently. Although red tides in Oman have been considered a consequence of upwelling in the summer season (May to September, recent phytoplankton outbreaks in Oman are not restricted to summer. Frequent algal blooms have been reported during winter (December to March. HABs may have contributed to hypoxia and/or other negative ecological impacts.

    2015-01-01

    Traditionally the focus of research and concern of environmental studies in the marine system is the impact of human activities in the ocean: the sources, distribution and fate of pollutants resulting from human activities. More recently, there has been recognition of the potential direct impact health can come from eating contaminated seafood, swimming in polluted water, and exposure to toxins from harmful algal blooms. This paper will present two areas of concern that illustrates the fact that the health of the oceans and the health of humans go hand in hand: chemical pollution from plastics in the ocean and harmful alga bloom. The nuclear methodologies than can be useful in these areas will also be introduced. It is hoped that through the recognition of the inter-dependence of the health of both humans and the oceans, efforts will be made to restore and preserve the oceans. (author)

    In recent decades, the diatom Didymosphenia geminata has emerged as nuisance species in river systems around the world. This periphytic alga forms large “blooms” in temperate streams, presenting a counterintuitive result: the blooms occur primarily in oligotrophic streams and rivers, where phosphorus (P) availability typically limits primary production. The goal of this study is to examine how high algal biomass is formed under low P conditions. We reveal a biogeochemical process by which D. geminata mats concentrate P from flowing waters. First, the mucopolysaccaride stalks of D. geminata adsorb both iron (Fe) and P. Second, enzymatic and bacterial processes interact with Fe to increase the biological availability of P. We propose that a positive feedback between total stalk biomass and high growth rate is created, which results in abundant P for cell division. The affinity of stalks for Fe in association with iron-phosphorus biogeochemistry suggest a resolution to the paradox of algal blooms in oliogotrophic streams and rivers.

    Phytoplankton blooms are uncoupled from grazing and are normally terminated by sedimentation. There are several potential mechanisms by which phytoplankton cells may settle out of the photic zone: sinking of individual cells or chains, coagulation of cells into aggregates with high settling...... velocities, settling of cells attached to marine snow aggregates formed from discarded larvacean houses or pteropod feeding webs, and packaging of cells into rapidly falling zooplankton fecal pellets. We quantified the relative significance of these different mechanisms during a diatom bloom in a temperate...... to marine snow aggregates formed from discarded larvacean houses, whereas settling of unaggregated cells was insignificant. Formation rates of phytoplankton aggregates by physical coagulation was very low, and losses by this mechanism were much less than 0.07 d(-1); phytoplankton aggregates were neither...

  2. The 1987–1989 Phytoplankton Bloom in Kaneohe Bay

    Directory of Open Access Journals (Sweden)

    Edward Laws

    2018-06-01

    Full Text Available A remarkable bloom of phytoplankton occurred in the southeast sector (SE of Kaneohe Bay from 1987 through 1989. During the bloom, concentrations of chlorophyll a at the former site of the Kaneohe municipal wastewater treatment plant outfall averaged a little more than 2 mg m–3 for a period of 40 months. The increase of chl a was accompanied by a roughly twofold increase in the percentage of chl a accounted for by cells retained on a 35-micron filter, a drawdown of silicate concentrations from roughly 10 μM to 3–4 μM, an increase of nitrate concentrations from roughly 0.5 to more than 3 μM, and an increase of phosphate concentrations from roughly 0.2 to 0.5 μM. Extraordinarily heavy rains on 31 December 1987 led to flooding and land runoff that briefly raised chl a concentrations in the bay to as high as 17 mg m–3, but the bloom in question developed more than one year before the 1987 New Year’s Eve flood. It was not caused by unusually heavy rainfall: the average rainfall during 1987–1989 was only 10% above the long-term average. Instead, the bloom appears to have been caused by a leak in the sanitary sewer line that was previously used to discharge secondary treated sewage into Kaneohe Bay. Ultimately, leaks in the sanitary sewer lines maintained by the City and County of Honolulu led to legal action and a consent decree that required upgrading and the renovation of the wastewater collection system.

  3. Environmental Chemistry and Chemical Ecology of "Green Tide" Seaweed Blooms.

    2015-09-01

    Green tides are large growths or accumulations of green seaweeds that have been increasing in magnitude and frequency around the world. Because green tides consist of vast biomasses of algae in a limited area and are often seasonal or episodic, they go through periods of rapid growth in which they take up large amounts of nutrients and dissolved gases and generate bioactive natural products that may be stored in the plants, released into the environment, or broken down during decomposition. As a result of the use and production of inorganic and organic compounds, the algae in these blooms can have detrimental impacts on other organisms. Here, we review some of the effects that green tides have on the chemistry of seawater and the effects of the natural products that they produce. As blooms are developing and expanding, algae in green tides take up inorganic nutrients, such as nitrate and ortho-phosphate, which can limit their availability to other photosynthetic organisms. Their uptake of dissolved inorganic carbon for use in photosynthesis can cause localized spikes in the pH of seawater during the day with concomitant drops in the pH at night when the algae are respiring. Many of the algae that form green-tide blooms produce allelopathic compounds, which are metabolites that affect other species. The best documented allelopathic compounds include dimethylsulfoniopropionate (DMSP), dopamine, and reactive oxygen species (ROS) and their breakdown products. DMSP and dopamine are involved in defenses against herbivores. Dopamine and ROS are released into seawater where they can be allelopathic or toxic to other organisms. Thus, these macroalgal blooms can have harmful effects on nearby organisms by altering concentrations of nutrients and dissolved gas in seawater and by producing and releasing allelopathic or toxic compounds. © The Author 2015.

  4. Modelling the production of dimethylsulfide during a phytoplankton bloom

    Science.gov (United States)

    Gabric, Albert; Murray, Nicholas; Stone, Lewi; Kohl, Manfred

    1993-12-01

    Dimethylsulfide (DMS) is an important sulfur-containing atmospheric trace gas of marine biogenic origin. DMS emitted from the oceans may be a precursor of tropospheric aerosols and cloud condensation nuclei (CCN), thereby affecting the Earth's radiative balance and possibly constituting a negative feedback to global warming, although this hypothesis is still somewhat controversial. The revised conceptual model of the marine pelagic food web gives a central role to planktonic bacteria. Recent experiments have shown that consumption of dissolved DMS by microbial metabolism may be more important than atmospheric exchange in controlling its concentration in surface waters and hence its ventilation to the atmosphere. In this paper we investigate the effect of the marine food web on cycling of dissolved DMS in surface waters during a phytoplankton bloom episode. A nitrogen-based flow network simulation model has been used to analyze the relative importance of the various biological and chemical processes involved. The model predictions suggest that the concentration of DMS in marine surface waters is indeed governed by bacterial metabolism. Environmental factors that affect the bacterial compartment are thus likely to have a relatively large influence on dissolved DMS concentrations. The ecological succession is particularly sensitive to the ratio of phytoplankton to bacterial nutrient uptake rates as well the interaction between herbivore food chain and the microbial loop. Importantly for the design of field studies, the model predicts that peak DMS concentrations are achieved during the decline of the phytoplankton bloom with a typical time lag between peak DMS and peak phytoplankton biomass of 1 to 2 days. Significantly, the model predicts a relatively high DMS concentration persisting after the phytoplankton bloom due to excretion from large protozoa and zooplankton, which may be an additional explanation for the lack of correlation between DMS and chlorophyll a

  5. Effect of Zeolite Treatment on the Blooming Behavior of Paraffin Wax in Natural Rubber Composites

    Directory of Open Access Journals (Sweden)

    Bryan B. Pajarito

    2016-06-01

    Full Text Available The blooming behavior of paraffin wax in natural rubber (NR composites was studied as function of zeolite treatment. Three types of zeolite treatment were treated as factors: acid activation using hydrochloric acid (HCl solution, ion exchange using tetradecyldimethyl amine (TDA chloride salt, and organic modification using glycerol monostearate (GMS. The zeolite was treated according to a 23 full factorial design of experiment. Attenuated total reflectance – Fourier transform infrared (ATR-FTIR spectroscopy was used to characterize the chemical structure of treated zeolite. Treated zeolite was applied as filler to NR composites deliberately compounded with high amount of paraff in wax. The amount of bloomed wax in surface of NR composite sheets was monitored with time at 50oC. Results show the bloom amount to be linear with the square root of time. NR composites reinforced with untreated, acid-activated, and ion-exchanged zeolite fillers indicate reduction in wax blooming as compared to unfilled NR. The bloom rate (slope and initial bloom (y-intercept were determined from the experimental plots. Analysis of variance (ANOVA shows the bloom rate to be signif icantly increased when zeolite fillers are treated with GMS. Meanwhile, initial bloom was significantly enhanced when zeolite fillers are treated with TDA chloride salt and GMS. The significant increase in bloom rate and initial bloom can be attributed to the softening of the NR matrix at high amounts of TDA chloride salt and GMS.

    To understand the variations of picoplankton (Prochlorococcus, Synechococcus, picoeukaryotes, and heterotrophic bacteria) abundances during diatom bloom, the distribution of picoplankton in the Taiwan Bank, South China Sea was investigated using flow cytometry during a Thalassiosira diporocyclus bloom in March 2016. The results indicated an abrupt abundance decrease for Prochlorococcus, Synechococcus, and picoeukaryotes within the bloom area while the abundance of heterotrophic bacteria showed no significant difference between the bloom and non-bloom areas. We found two sub-groups of heterotrophic bacteria: high- and low-nucleic acid content (HNA and LNA) bacteria with HNA dominated in the bloom area whereas LNA dominated in the non-bloom area. Among the picoplankton components, HNA represented the highest (61.1%) carbon biomass in the bloom area while picoeukaryotes represented the highest (37.6%) in the non-bloom area. Our findings implied that heterotrophic bacteria, especially HNA, played an essential role during the diatom bloom. Copyright © 2017 Elsevier Ltd. All rights reserved.

  7. Distribution and recurrence of phytoplankton blooms around South Georgia, Southern Ocean

    Full Text Available South Georgia phytoplankton blooms are amongst the largest of the Southern Ocean and are associated with a rich ecosystem and strong atmospheric carbon drawdown. Both aspects depend on the intensity of blooms, but also on their regularity. Here we use data from 12 yr of SeaWiFS (Sea-viewing Wide Field-of-view Sensor ocean colour imagery and calculate the frequency of bloom occurrence (FBO to re-examine spatial and temporal bloom distributions. We find that upstream of the island and outside the borders of the Georgia Basin, blooms occurred in less than 4 out of the 12 yr (FBO < 4. In contrast, FBO was mostly greater than 8 downstream of the island, i.e., to the north and northwest, and in places equal to 12, indicating that blooms occurred every year. The typical bloom area, defined as the region where blooms occurred in at least 8 out of the 12 yr, covers the entire Georgia Basin and the northern shelf of the island. The time series of surface chlorophyll a (Chl a concentrations averaged over the typical bloom area shows that phytoplankton blooms occurred in every year between September 1997 and September 2010, and that Chl a values followed a clear seasonal cycle, with concentration peaks around December followed in many years by a second peak during late austral summer or early autumn, suggesting a bi-modal bloom pattern. The bloom regularity we describe here is in contrast with results of Park et al. (2010 who used a significantly different study area including regions that almost never exhibit bloom conditions.

    2001-08-01

    Long-term information on possible changes in cyanobacterial blooms in the Baltic Sea, formed mainly by Nodularia spumigena and Aphanizomenon sp., was sought in published records in historical (years 1887-1938) and modern (years 1974-1998) phytoplankton data sets. Old and new sampling methods and fixatives were tested to improve the comparison of data that had been collected and analyzed in different ways. A hundred years ago, plankton was mainly of interest as a source of fish food; eutrophication problems were only locally reported from the coast, mainly in southern haffs and the receiving waters of larger cities. There were few recordings of open-sea blooms before World War II. Abundances of Nodularia spumigena and Aphanizomenon sp. were low in the old material, and 137 summer samples from 1887-1938 showed no peak abundance. High abundances are common in the new material, and the range of the numbers of both taxa has increased markedly relative to the old material. Since the 1960s, cyanobacterial blooms have been common in the open sea in both the Baltic proper and the Gulf of Finland, indicating high availability of nutrients.

    2010-06-01

    Weather plays an important role in spring-blooming fruit crops due to the combined effects on bee activity, flower opening, pollen germination, and fertilization. To determine the effects of weather on highbush blueberry, Vaccinium corymbosum L., productivity, we monitored bee activity and compared fruit set, weight, and seed number in a field stocked with honey bees, Apis mellifera L., and common eastern bumble bees, Bombus impatiens (Cresson). Flowers were subjected to one of five treatments during bloom: enclosed, open, open during poor weather only, open during good weather only, or open during poor and good weather. Fewer bees of all types were observed foraging and fewer pollen foragers returned to colonies during poor weather than during good weather. There were also changes in foraging community composition: honey bees dominated during good weather, whereas bumble bees dominated during poor weather. Berries from flowers exposed only during poor weather had higher fruit set in 1 yr and higher berry weight in the other year compared with enclosed clusters. In both years, clusters exposed only during good weather had > 5 times as many mature seeds, weighed twice as much, and had double the fruit set of those not exposed. No significant increase over flowers exposed during good weather was observed when clusters were exposed during good and poor weather. Our results are discussed in terms of the role of weather during bloom on the contribution of bees adapted to foraging during cool conditions.

    Lake Baikal is a UNESCO World Heritage Site and holds 20% of the world’s freshwater reserves. On July 26, 2016, a cyanobacterial bloom of a green colour a few kilometers in size with a bad odor was discovered by local people in the Barguzinsky Bay on the eastern shore of Lake Baikal. Our study showed very high concentration of chlorophyll a (41.7 g/m3) in the sample of bloom. We found that the bloom was dominated by a nitrogen-fixing heterocystous cyanobacteria of the genus Dolichospermum. The mass accumulation of cyanobacteria in the lake water with an extremely high chlorophyll a concentration can be explained by a combination of several factors: the discharge of biologicaly-available nutrients, including phosphorus, into the water of Lake Baikal; low wind speed and weak water mixing; buoyant cyanobacterial cells on the lake surface, which drifted towards the eastern coast, where the maximum concentration of chlorophyll a was recorded. In the center of the Barguzinsky Bay and in the open part of Lake Baikal, according to satellite data, the chlorophyll a concentration is several orders of magnitude lower than at the shoreline.

    During blooming, flower petals undergo significant shape changes. For lilies, various different mechanisms responsible for the change have been suggested [1,2]. One is that cell growth along the edge of a petal, or, more generally, a tepal, drives a transition from a cup shape (within a bud) to a saddle shape (within a bloom). This mechanism has been previously considered for tepals modeled as shallow elliptical shells whose thickness from the center, t, falls off at least as fast as t = t0 (1 - x2/a2 - y2/b2 ) [1]. Here t0 is the maximum thickness of the shell, a and b are the semimajor and semiminoraxes, x and y are the coordinates along the longitudinal and lateral axes. By measuring tepal thicknesses from images collected by x-ray tomography of intact buds and by photography of microtomed buds, we find that this condition is indeed met for both Lilium casablanca and Lilium lancifolium.

    Full Text Available In order to contribute to higher levels of job satisfaction, job involvement , and productivity, a match or fit should be established between the dominant career anchor associated with a specific occupation and that of the employee. A career anchor is an individual’s set of self-perceived talents, abilities, motives, needs and values that form the nucleus of one’s occupational self-concept. Psychologists have always been part of the service orientated careers and therefore one would expect that it is likely that their dominant career anchor would be service orientation. If this is the case, psychologists with service as their dominant career anchor are supposed to have greater job satisfaction and job involvement compared to those with different career anchors. However, according to literature, this assumption is not necessarily correct. The primary goals of the current study were to determine whether in fact service is the dominant career anchor of psychologists in the Free State and whether there are significant differences regarding job satisfaction and job involvement between psychologists with and without service as their dominant career anchor. A third goal was to determine whether psychologists with different dominant career anchors differ significantly from one another regarding job satisfaction and job involvement. Questionnaires measuring career orientations, job satisfaction and job involvement were sent to 165 of the 171 registered psychologists in the Free State region. Only 75 psychologists (45,5% responded which exceeded the traditional return rate of 20 to 30%. Due to the small sample of respondents, a nonparametric statistical test, namely the Mann Whitney U test was conducted to determine possible differences.

    Full Text Available The data of literary sources concerning the bloom of angiosperm plants and deviation in the development of a flower and inflorescence, in particular untimely flowering, was generalized; our observation results of some peculiarities of re-bloom of woody plants in the National Dendrological Park “Sofiyivka” of NAS of Ukraine (NDP “Sofiyivka” were discussed. The flowering process was formed during a long-term evolution of a propagation system of angiosperm plants as a basis of fertilization and further fruit and seed development. As a result of vernalization and photoperiodism reactions, flowering (under regular conditions occurs in the most favorable period for pollination and fertilization of every plant. However, various deviations, in particular, the untimely (most frequently double, sometimes three- and four-fold flowering occurs in this perfect process of generative organ formation of angiosperm plants. An increased number of reports about re-bloom (at the end of summer – at the beginning of fall of the representatives of various woody plant species whose flowers usually blossom in May-June prompts the analysis of the available information concerning the mechanisms of flowering and the causes which lead to deviation of flowering processes. Flowering of the woody plant representatives of the collection fund of the NDP “Sofiyivka” was studied; statistics about re-bloom in different cities of Ukraine were monitored. The classification of re-bloom facts was carried out according to V.L. Vitkovskiy (1984. Although this classification has mostly a stated nature, it was good enough when being formulated and, with certain conditions, it can be applied nowadays. Accordingly, using this classification, abnormal cases can include facts of early summer-fall flowering and early winter flowering. A late spring flowering can be adaptive response of damaged plants to exogenous stresses, due to which the probability of sexual propagation remains

    Algal blooms are a serious problem in waters, which damage aquatic ecosystems and threaten drinking water safety. However, the outbreak mechanism of algal blooms is very complex with great uncertainty, especially for large water bodies where environmental conditions have obvious variation in both space and time. This study developed an innovative method which integrated a self-organizing map (SOM) and fuzzy information diffusion theory to comprehensively analyze algal bloom risks with uncertainties. The Lake Taihu was taken as study case and the long-term (2004–2010) on-site monitoring data were used. The results showed that algal blooms in Taihu Lake were classified into four categories and exhibited obvious spatial–temporal patterns. The lake was mainly characterized by moderate bloom but had high uncertainty, whereas severe blooms with low uncertainty were observed in the northwest part of the lake. The study gives insight on the spatial–temporal dynamics of algal blooms, and should help government and decision-makers outline policies and practices on bloom monitoring and prevention. The developed method provides a promising approach to estimate algal bloom risks under uncertainties. - Highlights: • An innovative method is developed to analyze algal bloom risks with uncertainties. • The algal blooms in Taihu Lake showed obvious spatial and temporal patterns. • The lake is mainly characterized as moderate bloom but with high uncertainty. • Severe bloom with low uncertainty appeared occasionally in the northwest part. • The results provide important information to bloom monitoring and management.

  2. Politics and Israeli psychologists: is it time to take a stand?

    In Israel, it is quite rare for psychologists to relate to political and social issues. This remarkable tendency of psychologists to avoid dealing with such matters seems to supersede the common indifference or obtuseness of other groups in the Israeli public and similar groups in particular (e.g., physicians or social workers). Within this context, this paper focuses on the qualities and forms of reaction of the psychotherapeutic community in Israel to the national conflict that has been present intermittently since the late 1980s - namely, the two Intifadas. More specifically, as opposed to the current situation (the second Al-Aksa Intifada), in the course of the first Intifada (1987-1996), the voice of Israeli psychologists was clearly heard. Until now, this is the only exception to the rule of neutrality and passivity, in which psychologists in Israel became politically active. Specific elements of involvement of the therapeutic community is presented and discussed. Also, an attempt is made to suggest possible reasons to the very puzzling questions: Why then? Or what factors allowed for this change in position to occur? And more importantly, why did the protest of the psychologists in Israel vanish and their clear voices turn into silence?

    2009-10-01

    Full Text Available From 1946 the artist John Piper designed sets for eight of Benjamin Britten’s operas. In this article, John Piper’s contribution to the renaissance of English opera is considered in the wider context of the artistic and political reconstruction of England after the Second World War. During the War, Piper was one of the artists who redefined Englishness. As an abstract artist turned architectural painter, he created a pastoral vision of the national heritage whose preservation had become necessary. The designs form a part of Piper’s pictorial work whose logical conclusion found expression in stained-glass windows. From the architectural designs for The Rape of Lucretia to the window he designed for the new Coventry Cathedral and to the last opera sets for Death in Venice, he created backdrops for Britten’s works that provided a sense of aesthetic continuity whilst reflecting the contradictions of opera as a social form of art in post-war Britain.

    Narratives are ever more frequent in qualitative studies seeking to interpret experiences and the different viewpoints of individuals in a given context. Starting from this concept, the tradition that addresses narrative is reexamined, including the philosophy of Paul Ricoeur, the historical perspective of Walter Benjamin and the field of medical anthropology grounded in phenomenology. In Ricoeur, with hermeneutics as a variation derived from phenomenology, narrative is linked to temporality. In Benjamin, narrative comprised of bits and pieces, always inconclusive, emerges in spite of the official stories. If Ricoeur retrieves tradition from Gadamer as a fundamental component for the construction of the world of a text that makes imitation of life possible, Benjamin, faced with the collapse of tradition, suggests the invention of narrative forms outside the traditional canons, making it possible to hark to the past in order to change the present. Assumptions of medical anthropology are also presented, as they consider narrative a dimension of life and not its abstraction, namely an embodied and situated narrative. Lastly, three distinct research projects in mental health that use narrative linked to the theoretical concepts cited with their differences and similarities are presented.

  7. Blooming Trees: Substructures and Surrounding Groups of Galaxy Clusters

    We develop the Blooming Tree Algorithm, a new technique that uses spectroscopic redshift data alone to identify the substructures and the surrounding groups of galaxy clusters, along with their member galaxies. Based on the estimated binding energy of galaxy pairs, the algorithm builds a binary tree that hierarchically arranges all of the galaxies in the field of view. The algorithm searches for buds, corresponding to gravitational potential minima on the binary tree branches; for each bud, the algorithm combines the number of galaxies, their velocity dispersion, and their average pairwise distance into a parameter that discriminates between the buds that do not correspond to any substructure or group, and thus eventually die, and the buds that correspond to substructures and groups, and thus bloom into the identified structures. We test our new algorithm with a sample of 300 mock redshift surveys of clusters in different dynamical states; the clusters are extracted from a large cosmological N-body simulation of a ΛCDM model. We limit our analysis to substructures and surrounding groups identified in the simulation with mass larger than 1013 h ‑1 M ⊙. With mock redshift surveys with 200 galaxies within 6 h ‑1 Mpc from the cluster center, the technique recovers 80% of the real substructures and 60% of the surrounding groups; in 57% of the identified structures, at least 60% of the member galaxies of the substructures and groups belong to the same real structure. These results improve by roughly a factor of two the performance of the best substructure identification algorithm currently available, the σ plateau algorithm, and suggest that our Blooming Tree Algorithm can be an invaluable tool for detecting substructures of galaxy clusters and investigating their complex dynamics.

  8. Older Driver Safety: A Survey of Psychologists' Attitudes, Knowledge, and Practices.

    2016-09-01

    Using an online survey, we examined the knowledge, attitudes, and practices with respect to older driver safety concerns of clinical psychologists from across Canada who self-identified as working with at least some drivers over 60 years of age. Eighty-four psychologists completed the survey, and many were aware of the issues relevant to older driver safety, although only about half reported that assessing fitness to drive was an important issue in their practice. The majority (75%) reported that they would benefit from education concerning evaluation of fitness to drive. The primary recommendation emerging from this investigation is to increase efforts to inform and educate psychologists about driving-related assessment and regulatory issues in general, and specifically with respect to older adults. As the population ages, it is of growing importance for all health care providers to understand the influence of mental health conditions-including cognitive impairment and dementia-on driving skills.

    Full Text Available As with other areas, the growth of occupational and organizational psychology is based on scientific research, variety of situational factors and trends, and needs that arise in the organizational environment. The aim of the study was to describe the tasks carried out by psychologists in organizations in the past (55 years long history of the field in Slovenia, and to compare these with the tasks that are currently performed. The results were compared with similar studies that had been conducted in Slovenia. The results reveal that the work carried out by psychologists in organizations is currently more diverse, but also more focused on specific forms of work, particularly those related to psychological assessment, counseling, and motivation. Their duties are now more likely to be conducted in an international environment and involve working directly with employees and leaders. Participants also gave recommendations to psychologists who work or want to work in the field of organizational psychology.

    Mao, J Q; Lee, Joseph H W; Choi, K W

    2009-09-01

    A deterministic ecosystem model is combined with an extended Kalman filter (EKF) to produce short term forecasts of algal bloom and dissolved oxygen dynamics in a marine fish culture zone (FCZ). The weakly flushed FCZ is modelled as a well-mixed system; the tidal exchange with the outer bay is lumped into a flushing rate that is numerically determined from a three-dimensional hydrodynamic model. The ecosystem model incorporates phytoplankton growth kinetics, nutrient uptake, photosynthetic production, nutrient sources from organic fish farm loads, and nutrient exchange with a sediment bed layer. High frequency field observations of chlorophyll, dissolved oxygen (DO) and hydro-meteorological parameters (sampling interval Deltat=1 day, 2h, 1h, respectively) and bi-weekly nutrient data are assimilated into the model to produce the combined state estimate accounting for the uncertainties. In addition to the water quality state variables, the EKF incorporates dynamic estimation of algal growth rate and settling velocity. The effectiveness of the EKF data assimilation is studied for a wide range of sampling intervals and prediction lead-times. The chlorophyll and dissolved oxygen estimated by the EKF are compared with field data of seven algal bloom events observed at Lamma Island, Hong Kong. The results show that the EKF estimate well captures the nonlinear error evolution in time; the chlorophyll level can be satisfactorily predicted by the filtered model estimate with a mean absolute error of around 1-2 microg/L. Predictions with 1-2 day lead-time are highly correlated with the observations (r=0.7-0.9); the correlation stays at a high level for a lead-time of 3 days (r=0.6-0.7). Estimated algal growth and settling rates are in accord with field observations; the more frequent DO data can compensate for less frequent algal biomass measurements. The present study is the first time the EKF is successfully applied to forecast an entire algal bloom cycle, suggesting the

    2008-11-21

    The marine dinoflagellates commonly responsible for toxic red tides are parasitized by other dinoflagellate species. Using culture-independent environmental ribosomal RNA sequences and fluorescence markers, we identified host-specific infections among several species. Each parasitoid produces 60 to 400 offspring, leading to extraordinarily rapid control of the host's population. During 3 consecutive years of observation in a natural estuary, all dinoflagellates observed were chronically infected, and a given host species was infected by a single genetically distinct parasite year after year. Our observations in natural ecosystems suggest that although bloom-forming dinoflagellates may escape control by grazing organisms, they eventually succumb to parasite attack.

  17. Global paths of time-periodic solutions of the Benjamin-Ono equation connecting arbitrary traveling waves

    Energy Technology Data Exchange (ETDEWEB)

    Ambrose, David M.; Wilkening, Jon

    2008-12-11

    We classify all bifurcations from traveling waves to non-trivial time-periodic solutions of the Benjamin-Ono equation that are predicted by linearization. We use a spectrally accurate numerical continuation method to study several paths of non-trivial solutions beyond the realm of linear theory. These paths are found to either re-connect with a different traveling wave or to blow up. In the latter case, as the bifurcation parameter approaches a critical value, the amplitude of the initial condition grows without bound and the period approaches zero. We propose a conjecture that gives the mapping from one bifurcation to its counterpart on the other side of the path of non-trivial solutions. By experimentation with data fitting, we identify the form of the exact solutions on the path connecting two traveling waves, which represents the Fourier coefficients of the solution as power sums of a finite number of particle positions whose elementary symmetric functions execute simple orbits in the complex plane (circles or epicycles). We then solve a system of algebraic equations to express the unknown constants in the new representation in terms of the mean, a spatial phase, a temporal phase, four integers (enumerating the bifurcation at each end of the path) and one additional bifurcation parameter. We also find examples of interior bifurcations from these paths of already non-trivial solutions, but we do not attempt to analyze their algebraic structure.

  18. The Performer as Philosopher and Diplomat of Dissensus: Thinking and Drinking Tea with Benjamin Verdonck in Bara/ke (2000

    Directory of Open Access Journals (Sweden)

    Christel Stalpaert

    2015-04-01

    Full Text Available Ecology and activism is a burning issue in theatre and performance studies. However, following the French philosopher Bruno Latour, a radically new encounter with ecology is needed today, if eco-activism still wants to have a future. It seems that, in order to survive, eco-activism and eco-art have to move beyond their narrow and limited anthropocentric perspective. In this paradigm shift, the performer as philosopher – in the sense of a diplomat of dissensus – might play an important role. The Flemish artist and performer Benjamin Verdonck picks up this role of a performer as philosopher. In his artistic tree houses, Verdonck invites passers-by for coffee or tea and gently raises ecological issues. He performs protest as what I call “a diplomat of dissensus”, combining Latour’s writings on contemporary ecology and the function of the diplomat therein, and Jacques Rancière’s writings on dissensus and art in public space. Ecology, for its part, moves into the direction of what Félix Guattari in The Three Ecologies refers to as “the ethico-aesthetic aegis of an ecosophy” (Guattari 2000, 41, a contraction of ecology and philosophy that connects the environmental with a reflection on the psychic production of subjectivity and social relations.

    The aim of this study was to clarify, using a nationwide survey, what is perceived as necessary knowledge and skills for psychologists involved in cancer palliative care in Japan, the expectations of medical staff members, and the degree to which these expectations are met. We conducted a questionnaire survey of psychologists involved in cancer palliative care. A total of 419 psychologists from 403 facilities were asked to fill out the questionnaire and return it anonymously. Some 401 psychologists (89 males, 310 females, and 2 unspecified; mean age, 37.2 ± 9.5 years) responded about necessary knowledge and skills for psychologists working in cancer palliative care, the necessity for training, expectations at their current workplace, and the degree to which expectations are met. More than 90% of participants responded that many kinds of knowledge and skills related to the field of cancer palliative care are necessary. Over 80% of participants indicated a necessity for training related to these knowledge and skills. Although more than 50% (range, 50.1-85.8%) of participants responded that such services as "cooperation with medical staff within a hospital," "handling patients for whom psychological support would be beneficial," and "assessment of patients' mental state" were expected at their workplace, fewer than 60% (31.4-56.9%) responded that they actually performed these roles. Our results show that many psychologists in cancer palliative care feel unable to respond to the expectations at their current workplace and that they require more adequate knowledge and skills related to cancer palliative care to work effectively. No other nationwide surveys have generated this type of information in Japan, so we believe that the results of our study are uniquely important.

    Women's participation in the work force shifted markedly throughout the twentieth century, from a low of 21 percent in 1900 to 59 percent in 1998. The influx of women into market work, particularly married women with children, put pressure on the ideology of domesticity: an ideal male worker in the outside market married to a woman taking care of children and home (Williams, 2000). Here, we examine some moments in the early-to-mid-twentieth century when female psychologists contested established norms of life-work balance premised on domesticity. In the 1920s, Ethel Puffer Howes, one of the first generation of American women psychologists studied by Scarborough and Furumoto (1987), challenged the waste of women's higher education represented by the denial of their interests outside of the confines of domesticity with pioneering applied research on communitarian solutions to life-work balance. Prominent second-generation psychologists, such as Leta Hollingworth, Lillian Gilbreth, and Florence Goodenough, sounded notes of dissent in a variety of forums in the interwar period. At mid-century, the exclusion of women psychologists from war work galvanized more organized efforts to address their status and life-work balance. Examination of the ensuing uneasy collaboration between psychologist and library scholar Alice Bryan and the influential male gatekeeper E. G. Boring documents gendered disparities in life-work balance and illuminates how the entrenched ideology of domesticity was sustained. We conclude with Jane Loevinger's mid-century challenge to domesticity and mother-blaming through her questioning of Boring's persistent focus on the need for job concentration in professional psychologists and development of a novel research focus on mothering. © 2017 Wiley Periodicals, Inc.

  3. Hacia una crítica del historicismo: Gustave Flaubert y las tesis Sobre el concepto de Historia de Walter Benjamin

    Full Text Available In the seventh thesis of his essay On the concept of History, Walter Benjamin presents Gustave Flaubert as a representative figure of the empathic sensibility that underlies the historicist current of historiography. The first aim of this article is to analyze this mention and to confront it with other texts where Benjamin reflects on Flaubert: in this regard, it can be said that the concise judgment of the seventh thesis, in which Flaubert becomes the symbol of the inactive melancholy of historicism, can be challenged. Secondly, the article intends to prove that Flaubert’s literature (specially through the genre of historic novel as it is exemplified by Salammbô achieves two of the tasks that Benjamin assigns to the dialectical-materialistic historian: on one side, to be capable of hearing the grieving complaints of the defeated dead; on the other, to restitute potentiality in the past. En la séptima tesis del ensayo Sobre el concepto de Historia, Walter Benjamin presenta a Gustave Flaubert como la encarnación de la sensibilidad empática y pesimista que se encuentra en la base de la concepción historicista de la historia. El propósito de este trabajo es, en primer lugar, analizar esa mención contrastándola con el resto de los materiales benjaminianos en los que se hace mención de Flaubert: se verá que, así considerada, la fórmula apodíctica de la tesis (que erige al novelista como el emblema de la melancolía inactiva característica del historicismo admite ser matizada. En segundo lugar, se demostrará que la literatura de Flaubert (particularmente en su variante histórica encarnada por Salammbô cumple con dos de las tareas fundamentales que Benjamin asigna al historiador dialéctico-materialista: por un lado, disponerse a la escucha de los vencidos de la historia; por el otro, restituir la potencia del pasado.

    Full Text Available The modeling method has often been developed or recognized in various processes related to training of psychologists studies. It has educational value as its application favors the appropriation of skills and capacity necessary for the performance on the student. However, the method has limitations because it does not exhaust the content praxiological psychology in the teaching-learning process. Therefore, the modeling required to be valued its limitations and potentials in order to plan actions necessary to improve or complement other methods, which serve to improve the process of scientific and professional training of psychologists, with emphasis on the labor dimension.

    1989-12-01

    Is the clinical psychologist best characterized as a scientist-practitioner? Or does the practice of science and psychotherapy involve metaphysics to such an extent that the clinical psychologist ought to be considered a metaphysician-scientist-practitioner? To answer these questions, the roles, if any, of metaphysics in science and psychotherapy are examined. This article investigates this question by examining the views of the logical positivists, Karl Popper and Imre Lakatos, and concludes that the practice of science and psychotherapy involves metaphysics in (a) problem choice, (b) research and therapy design, (c) observation statements, (d) resolving the Duhemian problem, and (e) modifying hypotheses to encompass anomalous results.

    The present study aims to characterize the change in the composition and structure of the bacterial and microzooplankton planktonic communities in relation to the phytoplankton community composition during a bloom. High-throughput amplicon sequencing of regions of the 16S and 18S rRNA gene was undertaken on samples collected during a 20 day (d) mesocosm experiment incorporating two different nutrient addition treatments [Nitrate and Phosphate (NPc) and Nitrate, Phosphate and Silicate (NPSc)] as well as a control. This approach allowed us to discriminate the changes in species composition across a broad range of phylogenetic groups using a common taxonomic level. Diatoms dominated the bloom in the NPSc treatment while dinoflagellates were the dominant phytoplankton in the control and NPc treatment. Network correlations highlighted significant interactions between OTUs within each treatment including changes in the composition of Paraphysomonas OTUs when the dominant Chaetoceros OTU switched. The microzooplankton community composition responded to changes in the phytoplankton composition while the prokaryotic community responded more to changes in ammonia concentration.

  7. Allelopathic and Bloom-Forming Picocyanobacteria in a Changing World

    2018-01-01

    Full Text Available Picocyanobacteria are extremely important organisms in the world’s oceans and freshwater ecosystems. They play an essential role in primary production and their domination in phytoplankton biomass is common in both oligotrophic and eutrophic waters. Their role is expected to become even more relevant with the effect of climate change. However, this group of photoautotrophic organisms still remains insufficiently recognized. Only a few works have focused in detail on the occurrence of massive blooms of picocyanobacteria, their toxicity and allelopathic activity. Filling the gap in our knowledge about the mechanisms involved in the proliferation of these organisms could provide a better understanding of aquatic environments. In this review, we gathered and described recent information about allelopathic activity of picocyanobacteria and occurrence of their massive blooms in many aquatic ecosystems. We also examined the relationships between climate change and representative picocyanobacterial genera from freshwater, brackish and marine ecosystems. This work emphasizes the importance of studying the smallest picoplanktonic fractions of cyanobacteria.

    Full Text Available The eutrophication of waterways has led to a rise in cyanobacterial, harmful algal blooms (CyanoHABs worldwide. The deterioration of water quality due to excess algal biomass in lakes has been well documented (e.g., water clarity, hypoxic conditions, but health risks associated with cyanotoxins remain largely unexplored in the absence of toxin information. This study is the first to document the presence of dissolved microcystin, anatoxin-a, cylindrospermopsin, and β-N-methylamino-l-alanine in Jordan Lake, a major drinking water reservoir in North Carolina. Saxitoxin presence was not confirmed. Multiple toxins were detected at 86% of the tested sites and during 44% of the sampling events between 2014 and 2016. Although concentrations were low, continued exposure of organisms to multiple toxins raises some concerns. A combination of discrete sampling and in-situ tracking (Solid Phase Adsorption Toxin Tracking [SPATT] revealed that microcystin and anatoxin were the most pervasive year-round. Between 2011 and 2016, summer and fall blooms were dominated by the same cyanobacterial genera, all of which are suggested producers of single or multiple cyanotoxins. The study’s findings provide further evidence of the ubiquitous nature of cyanotoxins, and the challenges involved in linking CyanoHAB dynamics to specific environmental forcing factors are discussed.

  10. Is iron a limiting factor of Nodularia spumigena blooms?

    2003-12-01

    Full Text Available It is well known that a deficiency of iron, a trace element essential to every living organism, limits the growth of algae and cyanobacteria. Nodularia spumigena Mertens is a blue-green algae species inhabiting the Baltic region that often forms toxic blooms.     The aim of the study was to assess the growth of the toxic cyanobacteria with respect to iron bioavailability. The measured growth parameters were the numbers of cells (optical density, chlorophyll a and pheopigment a concentrations. The iron concentrations used ranged from 10-7 to 10-4 mol dm-3. Under iron stress conditions (<5 × 10-7 mol dm-3, growth inhibition, gradual pigment decay and cell mortality were observed. However, enriching the medium with complexing factors like citric acid and EDTA significantly stimulated the growth rate and chlorophyll a production. The citric acid - EDTA - Fe (5 × 10-7 mol dm-3 complex was demonstrably effective in stimulating the rate of cell division. Starting with 10-6 mol dm-3, the higher the iron(III concentration used in the media, the more intensive the growth of the cyanobacteria populations. This was most rapid in the presence of high iron concentrations (10-4 mol dm-3, regardless of the presence of complexing agents.     It appears that the growth of toxic cyanobacteria N. spumigena, and thus also its ability to form blooms, may well depend on iron availability in the environment.

  11. Lake level fluctuations boost toxic cyanobacterial "oligotrophic blooms".

    Directory of Open Access Journals (Sweden)

    Cristiana Callieri

    Full Text Available Global warming has been shown to strongly influence inland water systems, producing noticeable increases in water temperatures. Rising temperatures, especially when combined with widespread nutrient pollution, directly favour the growth of toxic cyanobacteria. Climate changes have also altered natural water level fluctuations increasing the probability of extreme events as dry periods followed by heavy rains. The massive appearance of Dolichospermum lemmermannii ( = planktonic Anabaena, a toxic species absent from the pelagic zone of the subalpine oligotrophic Lake Maggiore before 2005, could be a consequence of the unusual fluctuations of lake level in recent years. We hypothesized that these fluctuations may favour the cyanobacterium as result of nutrient pulses from the biofilms formed in the littoral zone when the lake level is high. To help verify this, we exposed artificial substrates in the lake, and evaluated their nutrient enrichment and release after desiccation, together with measurements of fluctuations in lake level, precipitation and D. lemmermannii population. The highest percentage of P release and the lowest C:P molar ratio of released nutrients coincided with the summer appearance of the D. lemmermannii bloom. The P pulse indicates that fluctuations in level counteract nutrient limitation in this lake and it is suggested that this may apply more widely to other oligotrophic lakes. In view of the predicted increase in water level fluctuations due to climate change, it is important to try to minimize such fluctuations in order to mitigate the occurrence of cyanobacterial blooms.

    2015-01-01

    This article reviews the occurrence of HABs in seawater, their effects on the operation of seawater reverse osmosis (SWRO) plants, the indicators for quantifying/predicting these effects, and the pretreatment strategies for mitigating operational issues during algal blooms. The potential issues in SWRO plants during HABs are particulate/organic fouling of pretreatment systems and biological fouling of RO membranes, mainly due to accumulation of algal organic matter (AOM). The presence of HAB toxins in desalinated water is also a potential concern but only at very low concentrations. Monitoring algal cell density, AOM concentrations and membrane fouling indices is a promising approach to assess the quality of SWRO feedwater and performance of the pretreatment system. When geological condition is favourable, subsurface intake can be a robust pretreatment for SWRO during HABs. Existing SWRO plants with open intake and are fitted with granular media filtration can improve performance in terms of capacity and product water quality, if preceded by dissolved air flotation or sedimentation. However, the application of advanced pretreatment using ultrafiltration membrane with in-line coagulation is often a better option as it is capable of maintaining stable operation and better RO feed water quality during algal bloom periods with significantly lower chemical consumption.

    One of the most significant impacts of global atmospheric change is the alteration of hydrological regimes and the associated disruption of hydrological connectivity within watersheds. We show how changes in the frequency, magnitude, and duration of hydrological connectivity and disconnectivity is compromising the capacity of forest soils to store organic carbon, and increasing its export to both aquatic and atmospheric systems. Increases in dissolved organic matter (DOM) loads from forested landscapes to aquatic systems and the shift of the DOM pool to a more refractory mixture of organic compounds, a process known as brownification, alters the physical and chemical characteristics of lake environments. Furthermore, by characterizing the stages of brownification (from low to high concentrations of refractory DOM), we show a shift in the limiting factors for phytoplankton growth from macronutrients (nitrogen -N- and phosphorus -P) to micronutrients (iron -Fe) and light availability. This shift is driven by the low concentrations of DOM supplying N and P in early stages of brownification, to the strong Fe-binding capacity of refractory DOM in brownified lakes. As lakes undergo brownification, cyanobacteria adapted to scavenge Fe from DOM-Fe complexes have a competitive advantage leading to the formation of cyanobacterial blooms. Our findings provide evidence that brownification is a driving force leading to cyanobacterial blooms in lakes on forested landscapes, with expected cascading consequences to lake food webs.

    The frequency and duration of macroalgal blooms have increased in many coastal waters over the past several decades. We used field surveys and laboratory culturing experiments to examine the nitrogen content and δ 15 N values of Ulva and Gracilaria, two bloom-forming algal genera in Narragansett Bay, RI (USA). The northern end of this bay is densely populated with large sewage treatment plant nitrogen inputs; the southern end is more lightly populated and opens to the Atlantic Ocean. Field-collected Ulva varied in δ 15 N among sites, but with two exceptions had δ 15 N above 10 per mille , reflecting a significant component of heavy anthropogenic N. This variation was not correlated with a north-south gradient. Both Ulva and Gracilaria cultured in water from across Narragansett Bay also had high signals (δ 15 N = ∼14-17 per mille and 8-12 per mille , respectively). These results indicate that inputs of anthropogenic N can have far-reaching impacts throughout estuaries

    In freshwater lakes, harmful algal blooms (HABs) of Cyanobacteria (blue-green algae) produce toxins that impact human health. However, little is known about the chemical species present in lake spray aerosol (LSA) produced from wave-breaking in freshwater HABs. In this study, a laboratory LSA generator produced aerosols from freshwater samples collected from Lake Michigan and Lake Erie during HAB and non-bloom conditions. Particles were analyzed for size and chemical composition by single particle mass spectrometry, electron microscopy, and fluorescence microscopy, with three distinct types of LSA identified with varying levels of organic carbon and biological material associated with calcium salts. LSA autofluorescence increases with blue-green algae concentration, showing that organic molecules of biological origin are incorporated in LSA from HABs. The number fraction of LSA with biological mass spectral markers also increases with particle diameter (greater than 0.5 μm), showing that HABs have size-dependent impacts on aerosol composition. The highest number fraction of LSA enriched in organic carbon were observed in particles less than 0.5 μm in diameter. Understanding the transfer of organic and biogenic material from freshwater to the atmosphere via LSA particles is crucial for determining health and climate effects due to HABs.

    Algal blooms of Karenia brevis, a harmful marine algae, occur almost annually off the west coast of Florida. At high concentrations, K. brevis blooms can cause harm through the release of potent toxins, known as brevetoxins, to the atmosphere. Epidemiologic studies suggest that aerosolized brevetoxins are linked to respiratory illnesses in humans. We hypothesized a relationship between K. brevis blooms and respiratory illness visits to hospital emergency departments (EDs) while controlling for environmental factors, disease, and tourism. We sought to use this relationship to estimate the costs of illness associated with aerosolized brevetoxins. We developed a statistical exposure-response model to express hypotheses about the relationship between respiratory illnesses and bloom events. We estimated the model with data on ED visits, K. brevis cell densities, and measures of pollen, pollutants, respiratory disease, and intra-annual population changes. We found that lagged K. brevis cell counts, low air temperatures, influenza outbreaks, high pollen counts, and tourist visits helped explain the number of respiratory-specific ED diagnoses. The capitalized estimated marginal costs of illness for ED respiratory illnesses associated with K. brevis blooms in Sarasota County, Florida, alone ranged from $0.5 to $4 million, depending on bloom severity. Blooms of K. brevis lead to significant economic impacts. The costs of illness of ED visits are a conservative estimate of the total economic impacts. It will become increasingly necessary to understand the scale of the economic losses associated with K. brevis blooms to make rational choices about appropriate mitigation.

    Interactions beween a high latitude, continental shelf, spring phytoplankton bloom and water column physics and chemistry were studied using 15 N measured rates of nitrogen uptake. Peak bloom conditions commenced when the mixed layer shallowed and minimized respirational losses. Integrative light-mixing growth models were accurate during early bloom stages. An advection-diffusion model associated peak bloom nitrate uptake with pycnocline mixing rates of 2.1 m d -1 in an 18 m mixed layer. Maximum nitrogen specific uptake rates (hr -1 ), unlike those of carbon, coincided with peak bloom conditions. Although species compositions among peak bloom periods were similar, particulate C/N ratios were not. Apparently, both intercellular factors and prevailing mixing conditions influence specific uptake rates and cell composition. A large proportion of new (nitrate) to total productivity was associated with the dominance of the early bloom forming diatoms in the mixed layer. In the absence of these net plankton the residual nanoplankton dominated community exhibited a greater dependence on regenerated nitrogen. Nitrate uptake averaged 700 mg-at m -2 during the spring bloom and 1 g-at m -2 year -1 . The yearly f factor was 0.40. Nitrogen uptake based carbon productivity was 188 g C m -2 year -1

    In 2015, a massive bloom of the marine diatom Pseudo-nitzschia, stretching from southern California to southern Alaska, resulted in significant impacts to coastal resources and marine life. This bloom was first detected in early May 2015, when Washington closed its scheduled razor clam digs on coastal beaches. It is the largest and longest-lasting bloom in at least the past 15 years, and concentrations of domoic acid in seawater, some forage fish, and crab samples have been among the highest ever reported for this region. By mid-May, domoic acid concentrations in Monterey Bay, California were 10 to 30 times the level that would be considered high for a normal Pseudo-nitzschia bloom. Impacts to coastal communities and marine life include shellfish and Dungeness crab closures in multiple states, impacting commercial, recreational and subsistence harvesters, anchovy and sardine fishery health advisories in some areas of California, and sea lion strandings in California and Washington. Other marine mammal and bird mortalities have been reported in multiple states, and domoic acid poisoning is a suspected cause. In addition to the spatial extent and toxicity, the bloom has also lasted for many months (ongoing as of September 2015). While the exact causes of the bloom's severity and early onset are not yet known, unusually warm surface water in the Pacific Ocean may be a contributing factor. Here we present an overview of the bloom dynamics and impacts, and preliminary analysis about the bloom initiation and relationship to unusual ocean conditions in 2014-2015.

    Harmful algal blooms are now recognized as a significant threat to the Chesapeake Bay as they can severely compromise the economic viability of important recreational and commercial fisheries in the largest estuary of the United States. This study describes the development of empirical models for the potentially domoic acid-producing Pseudo-nitzschia species complex present in the Bay, developed from a 22-year time series of cell abundance and concurrent measurements of hydrographic and chemical properties. Using a logistic Generalized Linear Model (GLM) approach, model parameters and performance were compared over a range of Pseudo-nitzschia bloom thresholds relevant to toxin production by different species. Small-threshold blooms (≥10 cells mL -1) are explained by time of year, location, and variability in surface values of phosphate, temperature, nitrate plus nitrite, and freshwater discharge. Medium- (100 cells mL -1) to large- threshold (1000 cells mL -1) blooms are further explained by salinity, silicic acid, dissolved organic carbon, and light attenuation (Secchi) depth. These predictors are similar to other models for Pseudo-nitzschia blooms on the west coast, suggesting commonalities across ecosystems. Hindcasts of bloom probabilities at a 19% bloom prediction point yield a Heidke Skill Score of ~53%, a Probability of Detection ˜ 75%, a False Alarm Ratio of ˜ 52%, and a Probability of False Detection ˜9%. The implication of possible future changes in Baywide nutrient stoichiometry on Pseudo-nitzschia blooms is discussed.

    Full Text Available The raphidophyte Chattonella marina (Subrahmanyan Hara & Chihara bloom which causes lethal effects on marine ecosystem has been reported intermittently from Indian waters. In the present study, periodic samplings were made in a Chattonella marina bloom area, off Mahe, on 27 and 29 October and 1 November 2011 (in different phases of the bloom to assess the associated bacterial population and their exoenzyme activity. Microbial community composition of Chattonella marina bloom revealed a twentyfold increase in bacterial load over the nonbloom area. The bacterial genera, Micrococcus, Flavobacterium, Vibrio, and Pseudomonas, increased significantly during the declining phase of the bloom. An assessment of the extracellular enzyme production also showed a marked increase in percentage of bacterial strains, potent in protease production, suggesting the possible role of proteolytic bacteria in bloom crash. This study reveals the bacterial community succession during the bloom and indicates that bacteria play an important role in bloom regulation.

    Satellite Chlorophyll a (CHL) data were used to investigate the influence of mesoscale anticyclonic eddies (AEs) and cyclonic eddies (CEs) on the timing of spring phytoplankton bloom initiation around the Yamato Basin (133-139°E and 35-39.5°N) in the Japan Sea, for the period 2002-2011. The results showed significant differences between AEs and CEs in the timing and initiation mechanism of the spring phytoplankton bloom. Blooms were initiated earlier in CEs which were characterized by shallow mixed-layer depths (mixed-layer depth. Conversely, blooms appeared in the AEs despite deeper mixed-layer depth (> 100 m) but close to the commencement of positive Q0. This suggests that the relaxation of turbulent mixing is crucial for the bloom initiation in AEs.

    Blooming of diatom species Chaetoceros curvisetus (Cleve, 1889) was observed in Junglighat Bay and Haddo Harbour of Port Blair Bay of Andaman and Nicobar Islands during June 2010. Physico-chemical parameters, nutrient concentrations and phytoplankton composition data collected from five stations during 2010 were classified as bloom area (BA) and non-bloom area (NBA) and compared. Elevated values of dissolved oxygen were recorded in the BA, and it significantly varied (p NBA. Among the nutrient parameters studied, nitrate concentration indicated significant variation in BA and NBA (p NBA, indicating its utilization. In Junglighat Bay, the C. curvisetus species constituted 93.4 and 69.2% composition of total phytoplankton population during day 1 and day 2, respectively. The bloom forming stations separated out from the non-bloom forming station in non-parametric multidimensional scaling (nMDS) ordinations; cluster analysis powered by SIMPROF test also grouped the stations as BA and NBA.

    A bloom of the dinoflagellate, Noctiluca scintillans (Macartney) was observed in Kalpakkam coastal waters during the second and third week of October, 1988. Associated with the incidence of the bloom, signficant variations in the distribution of intertidal hard bottom communities were observed. Considerable difference in the dissolved oxygen content was also recorded during the bloom period. A sudden disapperance of grazers like limpets was observed after the onset of the bloom. Subsequent to this, there was a recolonization process, which showed a regular succession. Following limpet disappearance there was a rapid 'greening' of the surface by Enteromorpha Later, Dictyota dichotoma excluded Enteromorpha. Experimental teak wood panels also showed a decline in cy prid settlement during the bloom. (author). 3 tabs., 19 refs

  13. Challenges in modeling spatiotemporally varying phytoplankton blooms in the Northwestern Arabian Sea and Gulf of Oman

    Science.gov (United States)

    Sedigh Marvasti, S.; Gnanadesikan, A.; Bidokhti, A. A.; Dunne, J. P.; Ghader, S.

    2016-02-01

    Recent years have shown an increase in harmful algal blooms in the Northwest Arabian Sea and Gulf of Oman, raising the question of whether climate change will accelerate this trend. This has led us to examine whether the Earth System Models used to simulate phytoplankton productivity accurately capture bloom dynamics in this region - both in terms of the annual cycle and interannual variability. Satellite data (SeaWIFS ocean color) show two climatological blooms in this region, a wintertime bloom peaking in February and a summertime bloom peaking in September. On a regional scale, interannual variability of the wintertime bloom is dominated by cyclonic eddies which vary in location from one year to another. Two coarse (1°) models with the relatively complex biogeochemistry (TOPAZ) capture the annual cycle but neither eddies nor the interannual variability. An eddy-resolving model (GFDL CM2.6) with a simpler biogeochemistry (miniBLING) displays larger interannual variability, but overestimates the wintertime bloom and captures eddy-bloom coupling in the south but not in the north. The models fail to capture both the magnitude of the wintertime bloom and its modulation by eddies in part because of their failure to capture the observed sharp thermocline and/or nutricline in this region. When CM2.6 is able to capture such features in the Southern part of the basin, eddies modulate diffusive nutrient supply to the surface (a mechanism not previously emphasized in the literature). For the model to simulate the observed wintertime blooms within cyclones, it will be necessary to represent this relatively unusual nutrient structure as well as the cyclonic eddies. This is a challenge in the Northern Arabian Sea as it requires capturing the details of the outflow from the Persian Gulf - something that is poorly done in global models.

    2012-02-01

    Cyanobacterial blooms are often a result of eutrophication. Recently, however, their expansion has also been found to be associated with changes in climate. To elucidate the effects of climatic variables on the expansion of cyanobacterial blooms in Taihu, China, we analyzed the relationships between climatic variables and bloom events which were retrieved by satellite images. We then assessed the contribution of each climate variable to the phenology of blooms using multiple regression models. Our study demonstrates that retrieving ecological information from satellite images is meritorious for large-scale and long-term ecological research in freshwater ecosystems. Our results show that the phenological changes of blooms at an inter-annual scale are strongly linked to climate in Taihu during the past 23 yr. Cyanobacterial blooms occur earlier and last longer with the increase of temperature, sunshine hours, and global radiation and the decrease of wind speed. Furthermore, the duration increases when the daily averages of maximum, mean, and minimum temperature each exceed 20.3 °C, 16.7 °C, and 13.7 °C, respectively. Among these factors, sunshine hours and wind speed are the primary contributors to the onset of the blooms, explaining 84.6% of their variability over the past 23 yr. These factors are also good predictors of the variability in the duration of annual blooms and determined 58.9% of the variability in this parameter. Our results indicate that when nutrients are in sufficiently high quantities to sustain the formation of cyanobacterial blooms, climatic variables become crucial in predicting cyanobacterial bloom events. Climate changes should be considered when we evaluate how much the amount of nutrients should be reduced in Taihu for lake management. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available In this article the analysis of professional standards in terms of the scope of work of the psychologist with clients in difficult life and legal situations. The criteria of analysis chosen: reflected in professional activities, the choice of grounds for the selection of professional activities that focus on a specific Department, selection of a particular direction of activity of the psychologist (prevention, support, rehabilitation. It is shown that all five of the analyzed standards imply such a situation, but only three of them ("educational psychologist", "Psychologist in the social sphere", "Specialist in rehabilitative work in the social sphere" describe the activities of the psychologist, and the remaining ("Expert of bodies of guardianship and guardianship concerning minors" and "Specialist in working with families" are more organizational in nature. The conclusion about compliance of the training programs developed by the Department of legal psychology and law and education, the requirements of professional standards, proposed improvements in these programs.

  16. Ethical Considerations for Psychologists Taking a Public Stance on Controversial Issues: The Balance Between Personal and Professional Life.

    2014-07-01

    Previous literature has documented the general issues psychologists often face while balancing their personal and professional lives. The struggle stems from attempting to satisfy the need to maintain a life outside of work while having the professional obligation to follow the American Psychological Association's (APA's) Ethical Principles of Psychologists and Code of Conduct (Ethics Code) to prevent their personal lives from interfering with their professional roles and relationships. The present paper analyzes the subject of psychologists taking a public position on controversial public issues. Although the APA Ethics Code does not restrict how psychologists conduct themselves during their personal time, taking a public stance on a controversial issue could potentially strain professional relationships and inadvertently reflect negatively on the profession. The present paper examines ethical issues that a) should be taken into account before psychologists take a public position on a controversial issue, and b) are in conflict with APA's Ethics Code or current research.
