We investigated the formation and microbial composition of a seasonal benthic nepheloid layer (BNL) in the eutrophic, monomictic southern basin of Lake Lugano. During stratification, a BNL developed at the sediment—water interface and progressively expanded 20–30 m into the water column, following the rising oxic—anoxic interface. The dominance of the fatty acids C16:1ω5, C16:1ω6, C16:1ω7, and C16:1ω8, with δ13C values between −62‰ (ω6) and −80‰ (ω7), suggests that the BNL was composed primarily of Type I aerobic methane oxidizing bacteria (MOB). Indeed, MOB contributed > 75% to the fatty acid carbon pool in the fully developed BNL, with cell densities up to 8.5 × 105 cells mL−1. In ex situ incubation experiments, CH4 turnover rate coefficients were up to 2.1 d−1, which translates into potential CH4 oxidation rates as high as 20 mmol m−3 d−1 under in situ CH4 concentrations. CH4 oxidation was limited by the diffusive supply of O2, and O2 consumption by aerobic CH4 oxidation (up to 13.1 mmol m−2 d−1) appears to be the primary driver of the seasonal growth of the BNL and expansion of the hypolimnetic anoxic zone. Methanotrophic activity at the interface between oxic and anoxic water masses can actuate the formation of a BNL, which in turn functions as an effective microbial CH4 filter in the water column, preventing CH4 transport to surface waters and evasion to the atmosphere. In situ biomass production by methanotrophic bacteria may represent, in addition to sediment resuspension and detritus trapping, a novel BNL formation mechanism.
Y a-t-il eu vraiment une rencontre entre Ricœur et la philosophie analytique?
Authors: Engel Pascal 
Published: July 2014

AbstractPaul Ricœur made a lot to introduce analytic philosophy in France during the 70s and 80s, and he engaged in a dialogue with a number of authors from this tradition, such as Austin, Strawson, Davidson or Parfit. This dialogue, though, was one-sided, since there was no discussion of his views by analytic philosophers. Moreover, Ricœur often misunderstood or misprepresented the analytic views that he was discussing. So in many ways the Ricœur’s encounter with analytic philosophy was unsuccessful, which does not mean that Ricœur’s discussions where unfruitful for his own work. RésuméPaul Ricœur a fait beaucoup pour introduire la philosophie analytique en France pendant les années 1970 et 1980, et il a entrepris un dialogue avec les auteurs de cette tradition, comme Austin, Strawson, Davidson ou Parfit. Mais ce dialogue est cependant resté unilatéral, car il n’y a pas eu de discussion des thèses de Ricœur au sein de la tradition analytique. De plus Ricœur a souvent mécompris les vues analytiques qu’il discutait. En ce sens il n’y a pas eu de rencontre entre Ricœur et les philosophes analytiques, ce qui ne veut pas dire que les discussions par Ricœur des philosophes anaytiques n’aient pas été fructueuses pour son œuvre propre.
Le dernier Wittgenstein et le dernier Husserl sur le langage
Authors: Ricoeur Paul 
Published: July 2014

This article presents an edited version of lectures given by Paul Ricœur at Johns Hopkins University in April 1966. Ricœur offers a comparative analysis of Wittgenstein’s and Husserl’s late works, taking the problem of language as the common ground of investigation for these two central figures of phenomenology and analytic philosophy. Ricœur develops his study in two parts. The first part considers Husserl’s approach to language after the Logical Investigations and concentrates on Formal and Transcendental Logic; leaving a transcendental reflection on language behind it re-examines a phenomenological conception, according to which the sphere of logic is not separable from that of experience. The main focus of the second part is Wittgenstein’s later philosophy as it moved on from the conception of an isomorphic relation between language and the world, as set out in the picture theory in the Tractatus Logico-Philosophicus, to the more pragmatic notion of a language-game in the Philosophical Investigations. In order to get beyond the irrevocable differences between the two philosophies and the unresolved theoretical issues on both sides, Ricœur suggests turning to a semiological paradigm based on the Saussurean distinction between “language” and “speaking.”Keyword: Analytic Philosophy, Husserl, Phenomenology, Semiology, Wittgenstein. Résumé Cet article est une version éditée de conférences données par Paul Ricœur à la Johns Hopkins University en avril 1966. Ricœur propose une analyse comparée des dernières œuvres de Wittgenstein et Husserl, avec le problème du langage comme sol commun d’investigations pour ces deux figures centrales de la phénoménologie et la philosophie analytique. Cette analyse de Ricœur se joue à travers deux parties. La première partie revient sur l'approche du langage chez Husserl depuis Recherches logiques avec une attention particulière aux développements de Logique formelle et logique transcendantale; dans le cadre d’une réflexion transcendantale sur le langage il revient sur une conception phénoménologique selon laquelle, le domaine du logique n’est pas séparable de celui de l'expérience. La deuxième partie se concentre principalement sur la dernière philosophie de Wittgenstein alors qu’il s'est départi de l’idée d’une relation isomorphique entre le langage et le monde telle que posée par la théorie du tableau dans le Tractatus logico-philosophicus, pour s’engager vers la notion plus pragmatique de jeu de langage dans les Investigations philosophiques. Afin de surmonter les différences irrémédiables entre les deux philosophies et, dans une certaine mesure, certains des problèmes théoriques non résolus depuis les deux bords, Ricœur fait finalement référence à un paradigme sémiologique et à la distinction saussurienne entre “langue” et “parole.”Mots-clés: Husserl, phénoménologie, sémiologie, philosophie analytique, Wittgenstein
Officers Under the Appointments Clause
Authors: Plecnik John T. 
Published: July 2014

Much ink has been spilled, and many keyboards worn, debating the definition of “Officers of the United States” under the Appointments Clause of Article II, Section 2, Clause 2 of the U.S. Constitution. Most recently, this debate has focused on the denizens of the Office of Appeals of the Internal Revenue Service (IRS). In Tucker I, the U.S. Tax Court faced the question of whether the settlement officers, appeals officers, and appeals team managers (collectively, IRS hearing officers) within the Office of Appeals are Officers or mere employees. In Tucker II, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) faced the same question on appeal. Both courts sided with the IRS in holding that none of the above are Officers. Although it hardly seems controversial to agree with the Tax Court and D.C. Circuit when the U.S. Supreme Court denies certiorari in the case, remarkably, all previous scholarship disputes the outcome of the Tucker decisions. This Article will defend that outcome as a proper application of Supreme Court precedent.
AVALIAÇÃO DE LÍNGUA PORTUGUESA EM PROVAS ESCOLARES DO SÉCULO XX (1935 e 1963)
Authors: Buim Arena Dagoberto , Pastorello Buim Arena Adriana 
Published: July 2014

O artigo analisa três provas escolares do ensino primário, duas de uma mãe e uma de seu filho, guardadas e fornecidas ao pesquisador pela mãe. As duas primeiras são de 30 de março e de 13 de novembro de 1935, do 3º. ano do Grupo Escolar Fernando Lobo, em Juiz de Fora, MG. A terceira foi produzida no Grupo Escolar Coronel Amâncio Bueno, em Jaguariúna, SP, em 28 de maio de 1963, em classe de 4º. ano. O conjunto dos dados analisados destaca produtos escolares resultantes das relações entre professor, aluno e cultura escolar. As provas são documentos tão importantes quanto os cadernos para compreender os produtos da cultura escolar e, como este artigo quer indicar, são meios para a inserção no mundo da cultura escrita. A metodologia de microanálise dos documentos revela registros sobre a estrutura das provas e o currículo da escola brasileira no ensino do português como língua materna em 1935 e 1963.

IMPASSE EPISTEMOLÓGICO E CURRICULAR NO COTIDIANO DAS PRÁTICAS DE ENSINO E NA FORMAÇÃO DE PROFESSORES DO SUDESTE GOIANO
Authors: Da Silva Sergio Pereira 
Published: July 2014

O texto analisa a dicotomia teoria x prática presente no cotidiano escolar e na formação de professores da região do sudeste goiano. Considera tal dicotomia um equívoco curricular e epistemológico. Sugere que a emergente demanda por pedagogias práticas e aparente exaustão dos discursos ético-políticos, além de condicionadas por projetos políticos e econômicos, são legitimadas por uma cultura acadêmica teoricista e, por vezes, indiferente aos desafios das práticas sociais.
ESTÁGIO E DOCÊNCIA: DIFERENTES CONCEPÇÕES
Authors: Lima Maria Socorro Lucena , Pimenta Selma Garrido 
Published: July 2014

Este artigo discute a formação de professores e pedagogos a partir da relação teoria e prática presente nas atividades de estágio. As autoras revelam preocupação com as práticas que “imitam modelos escolares”, assim como com as práticas escolares que priorizam a “instrumentalização técnica”. No sentido de superar este extremo/dicotomia, o estágio, segundo as autoras, não é percebido como um apêndice curricular, mas um instrumento pedagógico que contribui para a superação da dicotomia teoria&prática.
Sublimation and Affirmation in Nietzsche's Psychology
Authors: Swenson Joseph 
Published: July 2014

ABSTRACT
Nietzsche sometimes offers the elusive suggestion that his psychology is not just original, but inaugural: a “first” in the field of philosophy. This article argues that a clue to his inaugural ambitions is discovered in his novel use of sublimation as a concept that engages in both a genealogical critique and a therapeutic reassessment of the basic prejudices of value dualism that he claims constitute the evaluative core of the Western tradition. Genealogically, sublimation provides Nietzsche with a new structure of naturalistic narrative that explains how traditionally opposed values actually share a common natural origin. Therapeutically, Nietzsche's various sublimation narratives serve to qualify the effects of his own naturalistic critique by revealing how and why our animal bodies and drives can now be practically affirmed as a new source of human dignity.
Cardiovascular Drugs in Environmental Waters and Wastewaters: Method Optimization and Real Sample Analysis

Published: July 2014

Abstract
A sensitive method for determination of the eight most prescribed drugs used in combined cardiovascular therapy in Serbia was developed and optimized. The method was based on SPE followed by LC/ion trap-MS/MS with positive electrospray ionization. Parameters that affect the SPE were optimized, such as the eluent, sample pH, and sample volume. Good recoveries from groundwater (87.6–120.9%) as well as wastewater (84.5–106.6%) were achieved with this method, except in the case of atorvastatin (26.1 and 45.2%, respectively). The method was applied in the analysis of four river water samples collected in Serbia, as well as nine corresponding groundwater samples. Residues of the β-blockers metoprolol and bisoprolol as well as the anticoagulant clopidogrel were detected for the first time in river water. Groundwater samples did not contain drug residues. Influents and effluents of two wastewater treatment plants showed the predominant presence of metoprolol and enalapril. The removal rate of metoprolol was generally low, whereas enalapril was eliminated with the highest efficiency. Atorvastatin was detected in influents and completely removed in the treatment.

Abstract
A new coprecipitation methodology that used lutetium hydroxide as a precipitant for Cu(II), Pb(II), Mn(II), Co(II), Cd(II), Fe(III), and Ni(II) ions in herbal plant and water samples for analysis by atomic absorption spectrometry has been investigated. The parameters such as pH, amount of lutetium, and volume of aqueous sample were optimized for the recovery of these seven metals. The effects of concomitant ions on the separation-preconcentration of analytes were also checked. The validation of the procedure was checked with addition recovery tests and analysis of Standard Reference Material 1570a-Trace Elements in Spinach Leaves and TMDA-70 fortified lake water Certified Reference Material. The LODs for analyte ions were in the range of 1.7–7.2 μg/L. The application of the present procedure was successfully performed for the analysis of analyte contents of herbal plant samples from Turkey.

Published: July 2014

Abstract
A simple and selective separation and preconcentration method was developed for the determination of Cu(II) ions. This method is based on adsorption of Cu(II) ions from aqueous solution on a bis(3-aminopropyl)amine modified silica gel column and flame atomic absorption spectrometric determination after desorption. Various analytical parameters such as pH, type of eluent solution and its volume, flow rate of sample and eluent, and sample volume were optimized. Effects of some cation, anion, and transition metal ions on the recoveries of Cu(II) ions were also investigated. Cu(II) ions were quantitatively recovered at pH 6; 5.0 mL of 2 M HCl was used as the eluent. The preconcentration factor was found to be 150. The LOD was 0.12 μg/L for Cu(II). The accuracy of the method was confirmed by analysis of Tea Leaves (INCT-TL-1) and Fish Protein (DORM-3) certified reference materials. The optimized method was applied to various water and food samples for the determination of Cu(II).
Martian meteorites and Martian magnetic anomalies: A new perspective from NWA 7034

Published: July 2014

AbstractWe present the magnetic properties of the Noachian Martian breccia NWA 7034. Among the 25 unpaired Martian meteorites studied to date, NWA 7034 has a unique magnetic mineralogy. It contains about 15 wt % of iron oxides as magnetite that has experienced cation substitution and partial alteration to maghemite, with about a quarter of the oxides being pure maghemite. It also contains oxyhydroxides in the form of superparamagnetic goethite. The presence of maghemite and goethite makes NWA 7034 the most oxidized Martian meteorite. The overall magnetic assemblage is partly linked to near‐surface hydrothermal alteration. The high concentration of magnetic phases with high laboratory unblocking temperatures makes NWA 7034 a plausible analogue source lithology for the strong magnetization of the Martian Noachian crust. Near‐surface hydrothermal alteration can enhance the remanence of Martian rocks and account for local, high magnetic anomalies of shallow source.
Simulation of monsoon intraseasonal oscillations in a coarse‐resolution aquaplanet GCM

Published: July 2014

AbstractThe skill of the global climate models (GCMs) to realistically simulate the monsoon intraseasonal oscillations (MISOs) is related to the sensitivity of their convective parameterization schemes. Here we show that by coupling a simple multicloud parameterization to a coarse‐resolution aquaplanet GCM, realistic MISOs can be simulated. We conduct three different simulations with a fixed nonhomogeneous sea surface temperature mimicking the Indian Ocean/western Pacific warm pool (WP) centered at the three latitudes 5°N, 10°N, and 15°N, respectively, to replicate the seasonal migration of the Tropical Convergence Zone (TCZ). This results in the generation of mean circulation resembling the monsoonal flow pattern in boreal summer. Succession of eastward propagating Madden‐Julian Oscillation (MJO) disturbances with phase speed, amplitude, and structure similar to summer MJOs are simulated when the WP is at 5°N. When the WP is located over 10°N, northward and eastward propagating MISOs are simulated. This case captures the meridional seesaw of convection between continental and oceanic TCZ observed during boreal summer over South Asia. Westward propagating Rossby wave‐like disturbances are simulated when the WP is over 15°N congruous with the synoptic disturbances seen over the monsoon trough. The initiation of intraseasonal oscillations in the model can occur internally through organization of convective events above the WP associated with internal dynamics.
A SEEK filter assimilation of sea surface salinity from Aquarius in an OGCM: Implication for surface dynamics and thermohaline structure
Authors: Chakraborty Abhisek , Sharma Rashmi , Kumar Raj , Basu Sujit 
Published: July 2014

AbstractSingular Evolutive Extended Kalman (SEEK) filter has been used to assimilate Aquarius‐derived sea surface salinity (SSS) in a near‐global ocean general circulation model (OGCM). Advanced Very High Resolution Radiometer (AVHRR)‐derived sea surface temperature (SST) has also been assimilated in conjunction. The primary aim of the study is to investigate the improvement in simulation of global ocean surface currents as a result of this assimilation. The route of empirical orthogonal function (EOF) analysis has been taken for an efficient assessment of this impact separately in the space and time domains and satellite‐derived surface current has been used as a benchmark. As expected, the assimilation has been found to impart significant positive impact in both the domains. Also, joint assimilation of SSS and SST has been found to be better than standalone SSS assimilation. These results have been further corroborated by a comparison with buoy‐derived surface currents. Further emphasis has been laid on the simulation of Wyrtki and monsoon jets in the equatorial Indian Ocean, because of their importance in the climate of this region and again it has been found that assimilation guides the simulation toward realism in both the cases. Finally, impact on the SSS and SST fronts and their zonal displacements in the western Pacific has been investigated and here again the assimilation has led to an improvement in simulation of these features.
Accuracy of travel time distribution (TTD) models as affected by TTD complexity, observation errors, and model and tracer selection

Published: July 2014

AbstractAnalytical models of the travel time distribution (TTD) from a source area to a sample location are often used to estimate groundwater ages and solute concentration trends. The accuracies of these models are not well known for geologically complex aquifers. In this study, synthetic data sets were used to quantify the accuracy of four analytical TTD models as affected by TTD complexity, observation errors, model selection, and tracer selection. Synthetic TTDs and tracer data were generated from existing numerical models with complex hydrofacies distributions for 1 public‐supply well and 14 monitoring wells in the Central Valley, California. Analytical TTD models were calibrated to synthetic tracer data, and prediction errors were determined for estimates of TTDs and conservative tracer (
) concentrations. Analytical models included a new, scale‐dependent dispersivity model (SDM) for two‐dimensional transport from the water table to a well and three other established analytical models. The relative influence of the error sources (TTD complexity, observation error, model selection, and tracer selection) depended on the type of prediction. Geological complexity gave rise to complex TTDs in monitoring wells that strongly affected errors of the estimated TTDs. However, prediction errors for
and median age depended more on tracer concentration errors. The SDM tended to give the most accurate estimates of the vertical velocity and other predictions, although TTD model selection had minor effects overall. Adding tracers improved predictions if the new tracers had different input histories. Studies using TTD models should focus on the factors that most strongly affect the desired predictions.
BN‐Phenanthryne: Cyclotetramerization of an 1,2‐Azaborine Derivative

Published: July 2014

AbstractThermolysis of 9‐azido‐9‐borafluorene in heptane solution produces the tetramer of a BN‐phenanthryne. The isolation of the self‐trapping product provides evidence for the involvement of the BN‐aryne in the thermolysis reaction. Its formation may be rationalized by denitrogenation of the azide and ring enlargement.
