Countering the trend in contemporary ecocriticism to advance realism as an environmentally responsible mode of representation, this essay argues that the anti-realist aesthetics of literary modernism were implicitly “ecological.” In order to make this argument I distinguish between contemporary and modernist ecological culture (both of which I differentiate in turn from ecological science); while the former is concerned primarily with the practical reform characteristic of what we now call “environmentalism,” the latter demanded an all-encompassing reimagination of the relationship between humanity and nature. “Modernist ecology,” as I call it, attempted to envision this change, which would be ontological or metaphysical rather than simply social, through thematically and formally experimental works of art. Its radical vision, suggestive in some ways of today’s “deep” ecology, repudiated modern accounts of nature as a congeries of inert objects to be manipulated by a sovereign subject, and instead foregrounded the chiasmic intertexture of the subject/object relationship. In aesthetic modernism we encounter not “objective” nature, but “nature-being” – a blank substratum beneath the solid contours of what philosopher Kate Soper calls “lay nature” – the revelation of which shatters historical constructions of nature and alone allows for radical alternatives. This essay looks specifically at modernist ecology as it appears in the works of W. B. Yeats, D. H. Lawrence, and Samuel Beckett, detailing their attempts to envision revolutionary new ecologies, but also their struggles with the limited capacity of esoteric modernist art to effect significant ecological change on a collective level.

Populist radical right parties have become major political actors in Europe. This paper analyses the path and the different phases that have led them from the fringes of public debate to their present signifi cance, which is based on their capacity to attract electoral support and infl uence the political agendas in their respective countries. Besides, an analysis of the core ideological beliefs of these parties, and of the topics on which their mobilization capacity rests, is provided, as well as of the type of voters that are attracted by them. Finally, the authors discuss the meaning and impact of the growing popularity of the ideas and proposals put forward by the populist radical right parties.

Students reflect more on their learning in course subjects when they participate in managing their teaching–learning environment. As a form of guided participation, peer assessment serves the following purposes: (a) it improves the student’s understanding of previously established learning objectives; (b) it is a powerful metacognitive tool; (c) it transfers to the student part of the responsibility for assessing learning, which means deciding which learning activities are important and choosing the degree of effort a course subject will require; (d) it emphasizes the collective aspect of the nature of knowledge; and (e) the educational benefits derived from peer assessment clearly justify the efforts required to implement activities. This paper reports on the relative merits of a learning portfolio compiled during fine arts-related studies in which peer assessment played an important role. The researchers analyzed the student work load and the final marks students received for compulsory art subjects. They conclude that the use of a closed learning portfolio with a well-structured, sequential and analytical design can have a positive effect on student learning and that, although implementing peer assessment may be complex and students need to become familiar with it, its use is not only feasible but recommendable.

Coccolithophorids are enigmatic plankton that produce calcium carbonate coccoliths, which over geological time have buried atmospheric CO2 into limestone, changing both the atmosphere and geology of the Earth. However, the role of coccoliths for the proliferation of these organisms remains unclear; suggestions include roles in anti-predation, enhanced photosynthesis and sun-screening. Here we test the hypothesis that calcification stabilizes the pH of the seawater proximate to the organisms, providing a level of acidification countering the detrimental basification that occurs during net photosynthesis. Such bioengineering provides a more stable pH environment for growth and fits the empirical evidence for changes in rates of calcification under different environmental conditions. Under this scenario, simulations suggest that the optimal production ratio of inorganic to organic particulate C (PIC : POCprod) will be lower (by approx. 20%) with ocean acidification and that overproduction of coccoliths in a future acidified ocean, where pH buffering is weaker, presents a risk to calcifying cells.

Introdução: O alongamento coronário é um procedimento que pode envolver, ou não, técnicas cirúrgicas, e que tem como principal objetivo aumentar o tamanho da coroa clínica, assim como devolver a estética, a forma e a função às arcadas dentárias. Este procedimento realiza-se, ou por motivos estéticos ou motivos restauradores. Ultimamente, os motivos estéticos têm vindo a ganhar importância e são eles que, muitas da vezes, levam os pacientes às consultas de medicina dentária. O sorriso gengival é um desses motivos, e pode ser causado, entre outras razões por, uma erupção passiva alterada ou/e um excesso vertical maxilar. Estas são as etiologias que serão descritas neste trabalho. O aumento coronário realiza-se, também, quando há a necessidade de reabilitar um dente, quer seja com resinas compostas ou com coroas. Este, deve sempre respeitar os limites biológicos do periodonto, nomeadamente o espaço biológico. A invasão deste espaço pode por em risco a manutenção da saúde do periodonto e a viabilidade do tratamento a longo prazo, por isto, preconiza-se que deve ser deixado um espaço de 3mm, desde a crista óssea até a margem restauradora. As técnicas de alongamento coronário enumeradas e definidas ao longo desta tese são: a gengivectomia, o retalho apicalmente posicionado e a erupção dentária forçada. Cada uma delas possui as suas indicações e contra-inidcaçoes. A gengivectomia é realizada quando não há necessidade de recontorno ósseo, pelo contrário, quando essa necessidade existe opta-se pelo retalho apicalmente posicionado. A erupção forçada é uma alternativa ao alongamento cirúrgico e aplica-se, normalmente a dentes não restauráveis mas com estrutura dentária sã abaixo do da crista óssea. Um ótimo diagnóstico é o essencial para a escolha da técnica de aumento coronário que melhor se adequa a cada caso. Objetivo: O objetivo desta revisão bibliográfica tem por base a pesquisa das técnicas de alongamento coronário, começando por perceber a anatomia do periodonto, as alterações que nele acontecem antes e depois dos procedimentos de alongamento coronário, a descrição e a comparação dos mesmos. Materiais e métodos: Para a realização desta revisão foram utilizados os principais motores de busca de dados científicos como a PubMed, B-on, Medline, Scielo, Google Académico e ainda o repositório on-line da Universidade Fernando Pessoa. Foram utilizadas as seguintes palavras chaves: “altered passive eruption”, “gingivectomy”, “gingivoplasty”, “apically repositioned flap”, “surgical crown lengthening”, “biologic width”, “mucogengival junction”, “forced eruption”, “prostethic dentistry”, “gummy smile”, resultando num pesquisa de 45 artigos e duas obras literarátias de interesse. Conclusões: Foi possível concluir que existem varias técnicas de alongamento coronário, cada uma adequada a cada caso e verificou-se que existem vários motivos pelo qual se realiza essa técnica.

Introduction: Reporting guidelines (e. g. CONSORT) have been developed as tools to improve quality and reduce bias in reporting research findings. Trial registration has been recommended for countering selective publication. The International Committee of Medical Journal Editors (ICMJE) encourages the implementation of reporting guidelines and trial registration as uniform requirements (URM). For the last two decades, however, biased reporting and insufficient registration of clinical trials has been identified in several literature reviews and other investigations. No study has so far investigated the extent to which author instructions in psychiatry journals encourage following reporting guidelines and trial registration. Method: Psychiatry Journals were identified from the 2011 Journal Citation Report. Information given in the author instructions and during the submission procedure of all journals was assessed on whether major reporting guidelines, trial registration and the ICMJE's URM in general were mentioned and adherence recommended. Results: We included 123 psychiatry journals (English and German language) in our analysis. A minority recommend or require 1) following the URM (21%), 2) adherence to reporting guidelines such as CONSORT, PRISMA, STROBE (23%, 7%, 4%), or 3) registration of clinical trials (34%). The subsample of the top-10 psychiatry journals (ranked by impact factor) provided much better but still improvable rates. For example, 70% of the top-10 psychiatry journals do not ask for the specific trial registration number. Discussion: Under the assumption that better reported and better registered clinical research that does not lack substantial information will improve the understanding, credibility, and unbiased translation of clinical research findings, several stakeholders including readers (physicians, patients), authors, reviewers, and editors might benefit from improved author instructions in psychiatry journals. A first step of improvement would consist in requiring adherence to the broadly accepted reporting guidelines and to trial registration.

Hydroxyl radical (OH) is the primary oxidant in the troposphere, initiating the removal of numerous atmospheric species including greenhouse gases, pollutants that are detrimental to human health, and ozone-depleting substances. Because of the complexity of OH chemistry, models vary widely in their OH chemistry schemes and resulting methane (CH4) lifetimes. The current state of knowledge concerning global OH abundances is often contradictory. This body of work encompasses three projects that investigate tropospheric OH from a modeling perspective, with the goal of improving the tropospheric community’s knowledge of the atmospheric lifetime of CH4. First, measurements taken during the airborne CONvective TRansport of Active Species in the Tropics (CONTRAST) field campaign are used to evaluate OH in global models. A box model constrained to measured variables is utilized to infer concentrations of OH along the flight track. Results are used to evaluate global model performance, suggest against the existence of a proposed “OH Hole” in the tropical Western Pacific, and investigate implications of high O3/low H2O filaments on chemical transport to the stratosphere. While methyl chloroform-based estimates of global mean OH suggest that models are overestimating OH, we report evidence that these models are actually underestimating OH in the tropical Western Pacific. The second project examines OH within global models to diagnose differences in CH4 lifetime. I developed an approach to quantify the roles of OH precursor field differences (O3, H2O, CO, NOx, etc.) using a neural network method. This technique enables us to approximate the change in CH4 lifetime resulting from variations in individual precursor fields. The dominant factors driving CH4 lifetime differences between models are O3, CO, and J(O3-O1D). My third project evaluates the effect of climate change on global fields of OH using an empirical model. Observations of H2O and O3 from satellite instruments are combined with a simulation of tropical expansion to derive changes in global mean OH over the past 25 years. We find that increasing H2O and increasing width of the tropics tend to increase global mean OH, countering the increasing CH4 sink and resulting in well-buffered global tropospheric OH concentrations.

Mental illness affects a sizable minority of Americans at any given time, yet many people with mental illness (hereafter PWMI) remain unemployed or underemployed relative to the general population. Research has suggested that part of the reason for this is discrimination toward PWMI. This research investigated mechanisms that affect employment discrimination against PWMI. Drawing from theories on stigma and power, three studies assessed 1) the stereotyping of workers with mental illness as unfit for workplace success, 2) the impact of positive information on countering these negative stereotypes, and whether negatively-stereotyped conditions elicited discrimination; and 3) the effects of power on mental illness stigma components. I made a series of predictions related to theories on the Stereotype Content Model, illness attribution, the contact hypothesis, gender and mental health, and power. Studies tested predictions using, 1) an online vignette survey measuring attitudes, 2) an online survey measuring responses to fictitious applications for a middle management position, and 3) a laboratory experiment in which some participants were primed to feel powerful and some were not. Results of Study 1 demonstrated that PWMI were routinely stigmatized as incompetent, dangerous, and lacking valued employment attributes, relative to a control condition. This was especially evident for workers presented as having PTSD from wartime service and workers with schizophrenia, and when the worker was a woman. Study 2 showed that, although both war-related PTSD and schizophrenia evoke negative stereotypes, only schizophrenia evoked hiring discrimination. Finally, Study 3 found no effect of being primed to feel powerful on stigmatizing attitudes toward a person with symptoms of schizophrenia. Taken together, findings suggest that employment discrimination towards PWMI is driven by negative stereotypes; but, stereotypes might not lead to actual hiring discrimination for some labeled individuals.

Diskurse und Auseinandersetzungen mit den Fragen von Demokratie und Bildung und den Inhalten demokratischer Bildung sind in Österreich - so es sie überhaupt gibt - häufig verkürzt. Der Fokus liegt meist auf "Mitbestimmung". Fragen der Gestaltung der demokratischen Grundstrukturen und des demokratischen Grundverständnisses werden vernachlässigt. Das ist wohl u.a. auf die wenig aufgearbeitete autoritäre und faschistische Tradition in den meisten institutionellen Kontexten zurückzuführen. Die vorliegende Ausgabe des Magazin erwachsenenbildung.at fragt, was Demokratie kennzeichnet, wie viel und welche Art von Demokratie wir uns vorstellen können und wie viel Demokratie eine Gesellschaft braucht. Die Themenbeiträge entwickeln verschiedene, kritische, oft feministische Zugänge zum Demokratielernen und werden einerseits thematisch (critical science literacy, economic literacy), andererseits methodisch (Psychodrama, Legislatives Theater) mit direkten praktischen Bezügen ausgeführt. Die praxisorientierten Beiträge beschäftigen sich mit spezifischen Ansätzen (Anti-Bias-Ansatz, kritische Radioberichterstattung) und alten neuen Themen des Demokratielernens (politischer Extremismus, Geschlechterstereotype). Resümierend appellieren die Herausgeber, die institutionelle Einbindung zivilgesellschaftlicher Organisationsformen in die Erwachsenenbildungslandschaft und auch die verkürzten Diskurse um demokratische Bildung in Österreich genauer zu untersuchen.

Auch im betrieblichen Umfeld kann die Ausbreitung radikalistischer, rassistischer und rechtsextremer Tendenzen beobachtet werden. Was kann die gewerkschaftliche Weiterbildung im Rahmen der politischen Erwachsenenbildung hiergegen unternehmen? In der Arbeiterkammer Oberösterreich wurde eine Seminarreihe mit dem Titel "Extremismus - Was tun?" konzipiert, die sich in erster Linie an Betriebsrätinnen und Betriebsräte richtet. In insgesamt acht Einzelveranstaltungen sollen die Problematik von Alltagsrassismus, eigenen Vorurteilen, neuen gesellschaftlichen Entwicklungen und vor allem der Umgang mit diesen Herausforderungen im betrieblichen Umfeld erörtert werden. Der vorliegende Beitrag beschreibt die konzeptuellen Vorüberlegungen und Leitlinien der Bildungsarbeit der Arbeiterkammer und die Grundlagen, die Ausgestaltung und die Umsetzung dieses im Frühjahr 2016 gestarteten Erwachsenenbildungsprogramms.

El objetivo de este estudio fue analizar la fiabilidad y validez de las puntuaciones de la versión breve del Self-Description Questionnaire II (SDQ-II-S) en población chilena. La muestra se compuso de 1255 adolescentes chilenos, con un rango de edad de 13 a 17 años (M = 15.10; DT = 1.30). El análisis factorial confirmatorio corroboró la estructura original de 11 factores correlacionados del SDQ-II-S. La multidimensionalidad del cuestionario también fue avalada por la pequeña magnitud de las correlaciones entre los 11 factores (M = 0.26). Los coeficientes alfa de Cronbach variaron desde 0.70 hasta 0.84, y se destacó una adecuada fiabilidad. Para profundizar en el análisis de la validez de constructo del SDQ-II-S, se relacionaron las puntuaciones de las diferentes escalas con puntuaciones en medidas de ansiedad (Inventario de Ansiedad Estado-Rasgo) y autoeficacia (Escala de Autoeficacia Percibida Específica de Situaciones Académicas). Los resultados pusieron de manifiesto que estos cuestionarios permiten analizar constructos diferenciados aunque relacionados. Los datos de este trabajo destacan que el SDQ-II-S presenta adecuadas propiedades psicométricas en población chilena, contrarrestando las carencias existentes en lo que respecta a la evaluación del autoconcepto, y resaltan interesantes aplicaciones tanto en el ámbito aplicado como en el de la investigación.

Adaptability and invisibility are hallmarks of modern terrorism, and keeping pace with its dynamic nature presents a serious challenge for societies throughout the world. Innovations in computer science have incorporated applied mathematics to develop a wide array of predictive models to support the variety of approaches to counterterrorism. Predictive models are usually designed to forecast the location of attacks. Although this may protect individual structures or locations, it does not reduce the threat—it merely changes the target. While predictive models dedicated to events or social relationships receive much attention where the mathematical and social science communities intersect, models dedicated to terrorist locations such as safe-houses (rather than their targets or training sites) are rare and possibly nonexistent. At the time of this research, there were no publically available models designed to predict locations where violent extremists are likely to reside. This research uses France as a case study to present a complex systems model that incorporates multiple quantitative, qualitative and geospatial variables that differ in terms of scale, weight, and type. Though many of these variables are recognized by specialists in security studies, there remains controversy with respect to their relative importance, degree of interaction, and interdependence. Additionally, some of the variables proposed in this research are not generally recognized as drivers, yet they warrant examination based on their potential role within a complex system. This research tested multiple regression models and determined that geographically-weighted regression analysis produced the most accurate result to accommodate non-stationary coefficient behavior, demonstrating that geographic variables are critical to understanding and predicting the phenomenon of terrorism. This dissertation presents a flexible prototypical model that can be refined and applied to other regions to inform stakeholders such as policy-makers and law enforcement in their efforts to improve national security and enhance quality-of-life.

This article presents some of the findings of research on issues surrounding teaching terrorism and political violence at UK higher education institutions. It reports the results of a survey of UK institutions of higher education on their responses to government and other pressures in relation to terrorism. The data show a minority of universities have developed systems, policies or procedures for ‘preventing violent extremism’, while a significant number have developed close cooperation and collaboration with state counterterrorism policies raising potential issues of academic freedom. This article then examines three high-profile cases – incidents where universities, lecturers and students have come under political and legal pressures over the content of terrorism courses or accusations of ‘radicalisation’ on campus. It suggests that these pressures can be and sometimes are resisted, but that they have on occasion effectively narrowed the scope of academic freedom in practise with the danger that a further chilling effect follows in their wake.
