Published: September 2018

Nitrogen-doped titanium dioxide (N-doped TiO2) nanopowder was successfully prepared by the hydrothermal method. Titanium isopropoxide and urea were used as the starting precursors. The hydrothermal reaction was controlled at 200 °C for 2, 4 and 6 h. The white powder was obtained and dried for 24h. The crystal structure was identified by X-ray diffraction (XRD). A single phase of anatase structure was obtained without calcination steps. The morphology was investigated by field emission scanning electron microscopy (FESEM). The particles were irregular in shape and highly agglomerated. The chemical composition was determined by energy dispersive X-ray spectrometry (EDXS). The characteristic X-ray energy of titanium (Kα = 4.51 keV and Kβ = 4.93 keV), oxygen (Kα = 0.52 keV) and nitrogen (Kα = 0.39 keV) were observed. The functional group was identified by Fourier transform infrared spectrophotometry (FTIR). The wavenumbers in the range 668 to 1389 cm-1 corresponded to vibrations of Ti–O–Ti bond. The wavenumber in the range of 1442 to 1500 cm-1 could be attributed to the nitrogen species in the TiO2 network.
Hydrothermal Synthesis and Phase Formation Mechanism of TiO2(B) Nanorods via Alkali Metal Titanate Phase Transformation
Authors: Chimupala Yothin , Drummond-Brydson Rik
Published: September 2018

Titanium dioxide (B phase) with 1-D structures was successfully fabricated via a hydrothermal method with a subsequent ion-exchange process and calcination. P25, titanium isopropoxide (TTIP), rutile and also anatase were used as Ti precursors in the alkali hydrothermal system. TTIP promoted an elongation of nanorod morphology whereas the other precursors produced short nanorod structures. The different types of titanium precursors did not have any influence on the phase transformation during the fabrication process. Na2Ti6O13 was the primary intermediate product after washing the hydrothermal sample. H2Ti3O7 was the secondary intermediate phase obtained following proton-exchange of Na2Ti6O13 in HNO3 solution. Finally, the TiO2(B) phase was the product of calcination of the secondary intermediate product at 400°C for 5 hr. A phase transformation mechanism is presented based on an investigation of products at each of the steps. The effects of the synthesis conditions on tailoring of the crystal morphology are discussed. The growth direction of the TiO2(B) nanorods was investigated by HR-TEM and SADP. Finally, the metastable phase of TiO2(B) was shown to be transformed to anatase during thermal treatment at temperatures higher than 400°C.

Published: September 2018

Titanium dioxide nanotubes on titanium surface were prepared by electrolytic anodization in aqueous solution at constant voltages at room temperature for 2, 4 and 6 hours. Anodized titanium was heat treated in a furnace at 450 °C for 4 hours to convert amorphous structure to anatase and rutile crystalline structure. A scanning electron microscope was utilized for morphology investigation of the anodized titanium surfaces. For HF containing water media, porous surface on titanium was revealed after anodizing for 2 hours. Nanotubes (NT) were formed in this media at 4 and 6 hours anodizing time, the diameters of the tubes were approximately 70 to 100 nm. For HF/Na2SO4 aqueous solution, fine NTs, approximately 50 nm in diameter, were grown after 2 hours. However, the NTs obtained at anodizing time 4 and 6 hours were the same size, ranging from 100 to 120 nm. Anatase and rutile phases of TiO2 were formed in the anodized samples after annealing at 450 °C for 4 hours. The anodized samples were tested for their abilities to degrade Rhodamine B, to demonstrate their application as a material for waste water treatment. The Rhodamine B was degraded up to 41% in annealed sample anodized by electrolyte contained HF.

Published: September 2018

The p-CuxO core/n-ZnO shell heterostructure nanowire (NW) arrays were fabricated by thermal decomposition. Based upon the core/shell nanowire-based all oxide p-n junctions. The samples were analyzed by XRD, SEM, EDS and TEM. X-ray diffraction (XRD) analysis showed that the p-CuxO core/n-ZnO shell NW consisted of phase of p-CuxO and wurtzite phase of n-ZnO. The morphology analysis showed average diameter and length of nanowires of ̴ 50 to 200 nm and ̴ 10 to 30 µm, respectively. The EDS spectrum confirmed the presence of required elements in the p-CuxO core /n-ZnO shell NWs. It was found that Zn, O and Cu are distributed over the wire areas according to a ratio of 1:2 by atomic% ratio of Cu:Zn to get good core/shell structure. The TEM characterizations showed that the n-ZnO shell nanoparticles were comprised of n-ZnO polycrystalline nanoparticles (NPs) on the surface of p-Cu2O core NWs. The H2S gas sensing properties of the p-CuxO/n-ZnO NWs were evaluated in air containing dilute H2S gas at sensing temperatures (T) of 350°C. The response of 20.6 for p-CuxO/n-ZnO NW sensor to H2S gas was enhanced compared to that of the n-ZnO NW. The enhanced response of p-CuxO/n-ZnO NW sensor is due to increasing surface area, the increased amount of chemisorbed oxygen species on NP surface and the increased conductivity.
Subconjunctival bevacizumab versus mitomycin c as adjuvant treatment to subscleral trabeculectomy
Authors: El-Kasaby Mohamed I.
Published: September 2018

Aim

To compare the clinical outcome of adjuvant subconjunctival bevacizumab (BVZ) injection versus mitomycin C (MMC) during subscleral trabeculectomy.

Patients and methods

In this study, 20 patients who were divided into two groups: group A included 10 (20 eyes) patients who underwent subscleral trabeculectomy with subconjunctival injection of 1.25 mg/0.1 ml BVZ, and group B included 10 (20 eyes) patients who underwent subscleral trabeculectomy with adjuvant intraoperative use of 0.2 mg/ml MMC for 2 min. This prospective nonrandomized clinical comparative study was conducted in Nour-El-Hayaha Eye Center (Cairo). Patients were diagnosed for primary open angle glaucoma with uncontrolled intraocular tension by maximum tolerable antiglaucoma therapy. The study excluded patients with neovascular glaucoma, congenital and juvenile glaucoma, history of ocular pathology, or surgery as retinal surgeries and uveitis.

Results

Twenty patients were considered for the study, nine (45%) patients (18 eyes) were males and 11 (55%) patients (22 eyes) were females. The patients’ ages ranged from 35 to 65 years (mean age 55.2±8.3). Mild hyphema, in one eye in group A (8.33%), wound leak in one (8.33%) eye in each group, and shallow anterior chamber in two (16.7%) cases in each group. It was the most common encountered complication in our study. One (8.33%) case of shallow anterior chamber in group A led to choroidal effusion. One (8.33%) case in group B developed late bleb-related endophthalmitis after 3 months, which ended in phthisis bulbi.

Conclusion

The success of glaucoma filtration surgery is heralded by a wound healing response mainly mediated by fibroblast proliferation, migration, and contraction that leads to postoperative subconjunctival scar. The effect of subconjunctival BVZ and MMC-augmented trabeculectomy in cases of primary open angle glaucoma was beneficial in improving the success rate with better intraocular pressure control and prolonging the trabeculectomy survival with no significant difference between the two groups.
Transepithelial versus standard corneal collagen cross-linking for treatment of grades 1–3 keratoconus
Authors: El-Kasaby Mohamed I.
Published: September 2018

Purpose

The purpose of this article was to assess the safety and efficacy of transepithelial corneal collagen cross-linking (epithelial on) versus standard (epithelial off) technique in halting the progression of keratoconus.

Patients and methods

A prospective nonrandomized interventional comparative standard technique was conducted, which divided 40 patients into two groups: in group A, 34 eyes of 24 patients were enrolled and treated by transepithelial cross-linking, and in group B, 28 keratoconus eyes of 16 patients were included and treated by the standard technique. In group A, a solution of riboflavin 0.1%, dextran T500, trometamol, and EDTA (trans-Ribo) was instilled. In group B the epithelium was removed and riboflavin 0.1 solution (10 mg of riboflavin-5-phosphate in a 20% dextran T500 10 ml solution Ricrolin was instilled. Ultraviolet A irradiation (Food and Drug Administration approval) Avedro system was used with total energy 7.2, power intensity 30 mW, induction time 10 min, ultraviolet time continuous 4 min, and ultraviolet time pulse 8 min, but in transepithelial cross-linking, the intensity was 45 mW. Preoperative and postoperative assessments were performed at baseline and 3, 6, and 12 months postoperatively.

Results

Group A showed statistically highly significant differences between mean uncorrected visual acuity (UCVA) and mean UCVA at first, sixth, and 12th months postoperatively. In group B, there were statistically highly significant differences between mean UCVA preoperatively and the mean UCVA at first, sixth, and 12th months postoperatively. In group A, there were statistically significant differences between mean Km (mean k power) preoperatively and mean Km at the first and at 12th months postoperatively, whereas in group B, there were statistically significant differences between mean Km preoperatively and the mean Km at first month and statistically insignificant difference at third, sixth, and 12th months postoperatively.

Conclusion

Both epithelial-on and epithelial-off techniques appeared to correct best-corrected visual acuity but epithelial-off technique was more effective in reduction of KM, astigmatism, Q-value and anterior elevation. Moreover, epithelial off showed to halt keratoconus progression more than epithelial-on technique.
Detection of early left ventricular and left atrial dysfunction in type I diabetes mellitus using two dimensional speckle tracking echocardiography
Authors: Ahmed Taghreed A. , Hassan Mona N. , Mazen Adel A. , Hegazy SHreen A.
Published: September 2018

Background

Occult left ventricular (LV) systolic and diastolic dysfunction is not uncommon among young adults with type I diabetes mellitus (T1DM). Early detection in the subclinical phase may enhance different preventive strategies. The two-dimensional speckle tracking echocardiography (2D-STE) is a novel and promising tool for the detection of early changes in LV and left atrial (LA) myocardial performance.

Aim

To detect early LV and LA dysfunction in young adults with T1DM by 2D-STE and its correlation with their functional capacity using the treadmill stress test.

Patients and methods

Thirty patients with T1DM and 15 nondiabetics acting as controls were enrolled. Conventional 2D echo, tissue Doppler imaging (TDI), and 2D-STE were done. Peak LV global longitudinal strain and peak LA global longitudinal strain were obtained. The functional capacity was assessed using the treadmill stress test.

Results

A statistically significant decrease in the average peak LV global longitudinal strain was found in diabetics compared to nondiabetics (15.8±6.8 and 23.9±2.7, respectively; P<0.001) and in LV TDI strain rate (19.7±5.4 and 23±2.7, respectively® P<0.05) were found. A statistically significant peak atrial longitudinal strain decrease in the average in diabetics compared to nondiabetics (34.40±12.9 and 42.3±3.9, respectively, P<0.05). There were no significant differences between the two groups with respect to the functional capacity of the parameters.

Conclusion

Since T1DM is associated with early (subclinical) LV and LA dysfunction, 2D-STE becomes an important and sensitive tool for an early detection of subclinical LV and LA myocardial dysfunction.
Mean-field limit for collective behavior models with sharp sensitivity regions
Authors: Carrillo José A. , Choi Young-Pil , Hauray Maxime , Salem Samir
Published: September 2018

We rigorously show the mean-field limit for a large class of swarming individual based models with local sharp sensitivity regions. For instance, these models include nonlocal repulsive-attractive forces locally averaged over sharp vision cones and Cucker–Smale interactions with discontinuous communication weights.We define global-in-time solutions through a differential inclusion system corresponding to the particle descriptions. We estimate the error between the solutions to the differential inclusion system and weak solutions to the expected limiting kinetic equation by employing tools from optimal transport theory. Quantitative bounds on the expansion of the 1-Wasserstein distance along flows based on a weak-strong stability estimate are obtained. We also provide various examples of realistic sensitivity sets satisfying the assumptions of our main results.

Published: September 2018

Social influence affects college students’ gambling behaviours. However, few studies have experimentally investigated the influence of social interaction on college students’ gambling behaviour, and those studies that have yielded mixed findings. Women college students (n = 109) who endorsed recreational gambling behaviour were randomly assigned to gamble on electronic gambling machines (EGMs) in three conditions: warm social interaction from a confederate (i.e., initiating and maintaining conversation), cold social interaction from a confederate (i.e., refraining from initiating and maintaining conversation), or gambling alone. On average, participants in the warm social interaction condition placed significantly fewer spins and spent more time placing bets on the EGMs compared to the cold social interaction and no confederate conditions. When examining gambling behaviour over time, participants in the warm social interaction condition increased their bet size and the time between their bets over time compared to the cold interaction and no confederate conditions. These results suggest that interpersonal interactions significantly affect gambling behaviour. However, future research is needed to investigate these social processes in other forms of gambling and other gambling experiences.RésuméL’influence sociale affecte les comportements de jeu des étudiants collégiaux et universitaires. Cependant, peu d’études ont analysé de manière expérimentale l’influence de l’interaction sociale sur le comportement de jeu des étudiants, et les études ont donné des résultats mitigés. Les étudiantes (n = 109) qui ont adopté un comportement de jeu récréatif ont été affectées au hasard à des jeux électroniques en fonction d’une des trois conditions suivantes : avec interaction sociale amicale d’un camarade (c.-à-d., qui amorce et entretient la conversation), avec interaction sociale froide d’un camarade (qui s’abstient d’amorcer et d’entretenir la conversation) ou en solitaire. En moyenne, les participantes en condition d’interaction sociale amicale ont joué beaucoup moins de tours et ont consacré plus de temps à parier sur les appareils de jeu électroniques, comparées à ceux qui étaient en interaction sociale froide ou en solitaire. En examinant le comportement de jeu sur une période donnée, les participantes en condition d’interaction sociale amicale ont augmenté la taille des paris et la durée entre les paris par rapport à celles qui étaient dans une interaction sociale froide et en solitaire. Ces résultats font ressortir que les interactions interpersonnelles affectent de manière importante le comportement du jeu. Cependant, d’autres recherches doivent être effectuées pour analyser ces processus sociaux dans d’autres formes de jeux de hasard et d’autres expériences de jeu.

Abstract. A number of inorganic (nitryl chloride, ClNO2; chlorine,
Cl2; and hypochlorous acid, HOCl) and chlorinated, oxygenated volatile
organic compounds (ClOVOCs) have been measured in Manchester, UK during
October and November 2014 using time-of-flight chemical ionisation mass
spectrometry (ToF-CIMS) with the I− reagent ion. ClOVOCs appear to be
mostly photochemical in origin, although direct emission from vehicles is
also suggested. Peak concentrations of ClNO2, Cl2 and HOCl reach
506, 16 and 9 ppt respectively. The concentrations of ClNO2 are
comparable to measurements made in London, but measurements of ClOVOCs,
Cl2 and HOCl by this method are the first reported in the UK. Maximum
HOCl and Cl2 concentrations are found during the day and ClNO2
concentrations remain elevated into the afternoon if photolysis rates are
low. Cl2 exhibits a strong dependency on shortwave radiation, further
adding to the growing body of evidence that it is a product of secondary
chemistry. However, night-time emission is also observed. The contribution of
ClNO2, Cl2 and ClOVOCs to the chlorine radical budget suggests
that Cl2 can be a greater source of Cl than ClNO2, contributing
74 % of the Cl radicals produced on a high radiant-flux day. In contrast,
on a low radiant-flux day, this drops to 14 %, as both Cl2 production
and loss pathways are inhibited by reduced photolysis rates. This results in
ClNO2 making up the dominant fraction (83 %) on low radiant-flux
days, as its concentrations are still high. As most ClOVOCs appear to be formed
photochemically, they exhibit a similar dependence on photolysis,
contributing 3 % of the Cl radical budget observed here.

Abstract. We present a method to derive atmospheric-observation-based estimates of carbon dioxide (CO2) fluxes at the national scale, demonstrated using data from a network of surface tall tower sites across the UK and Ireland over the period 2013–2014. The inversion is carried out using simulations from a Lagrangian chemical transport model and an innovative hierarchical Bayesian Markov chain Monte Carlo (MCMC) framework, which addresses some of the traditional problems faced by inverse modelling studies, such as subjectivity in the specification of model and prior uncertainties. Biospheric fluxes related to gross primary productivity and terrestrial ecosystem respiration are solved separately in the inversion and then combined a posteriori to determine net primary productivity. Two different models, CARDAMOM and JULES, provide prior estimates for these fluxes. We carry out separate inversions to assess the impact of these different priors on the posterior flux estimates and evaluate the differences between the prior and posterior estimates in terms of missing model components. The Numerical Atmospheric dispersion Modelling Environment (NAME) is used to relate fluxes to the measurements taken across the regional network. Posterior CO2 estimates from the two inversions agree within estimated uncertainties, despite large differences in the prior fluxes from the different models. With our method, averaging results from 2013 and 2014, we find a total annual net biospheric flux for the UK of −8 ± 79 Tg CO2 yr−1 (CARDAMOM prior) and −64 ± 85 Tg CO2 yr−1 (JULES prior), where -ve values represent an uptake of CO2. These biospheric CO2 estimates show that annual UK biospheric sources and sinks are roughly in balance. These annual mean estimates are consistently higher than the prior estimates, which show much more pronounced uptake in the summer months.

Experiências migratórias e intergeracionais sobre a amamentação no espaço familiar: um estudo de representações sociais
Authors: Moreira Michelle Aráujo , Paiva Mirian Santos , Ramos Maria Natália Pereira , Ribeiro Polliana Santos , Mendes Ramos Jessica Suellen Barbosa
Published: September 2018

Objetivos: analizar las experiencias intergeneracionales de mujeres migrantes de la misma familia sobre la lactancia; se aprehende las representaciones sociales de esa población a lo largo de las generaciones sobre la experiencia de amamantar. Material y métodos: investigación cualitativa, fundamentada en la Teoría de las Representaciones Sociales y realizada con 63 mujeres de la misma familia y de diferentes generaciones, 21 tríadas en total. Se utilizó, para la recolección de los datos, la Prueba de Asociación Libre de Palabras y, para el análisis de éstos, el software Tri-Deux-Mots. Resultados: para las mujeres migrantes, la práctica de amamantar permanece ligada a beneficios fisiológicos y emocionales para el hijo, exigiendo abnegación y satisfacción. En la lactancia, las mujeres que se desplazan a nuevos territorios son más vulnerables como consecuencia de la adaptación geográfica, sociocultural y afectiva a la que serán sometidas. El proceso migratorio puede influir en la lactancia y estar en el origen de conflictos de maternidad, especialmente entre generaciones más jóvenes, pues éstas necesitan referencias familiares que, muchas veces, permanecen distantes o ausentes. Conclusiones: la diversidad sociocultural y el territorio influencian gran parte de las mujeres migrantes que amamantan, haciéndose necesario comprender los determinantes regionales y culturales, y las influencias familiares y generacionales que permean ese proceso.
The Use of the Blockchain Protocol by Public Administration as an Accomplishment of Efficiency in the Public Service
Authors: Rangel da Silva Felipe , Giublin Teixeira Rodrigo Valente
Published: September 2018

Bitcoin emerged as a proposal to revolutionize the current financial system. Due to its reliability, it has become popular and has since caught the attention of governments and world leaders. However, what can cause even more impact, not only in financial matters, is one of its components that gives rigidity and veracity to the information conducted within the application: the protocol blockchain. This mechanism of data storage and processing, compared to an open book, can reinvent the exchange and storage of information on the internet. It is already being used by companies to increase productivity and, mainly, to guarantee security against fraud and external attacks, such as ransomwares. Except for the complexity of technical issues that will not be determined due to the thematic limitation, this study proposes to indicate the use of the protocol blockchain as a possibility of security guarantee of public data also by the public initiative, in order to assure more efficiency of the service provided.
SME Managers and Financial Literacy; Does Financial Literacy Really Matter?
Authors: Akhtar Shamim , Liu Yanping
Published: September 2018

The purpose of this study is to examine the level of small and medium (SMEs) business owners-managers’ financial literacy and its effect on the firm’s performance. The study applied random sample and structural equation modeling approaches in measuring the impact of SME firm owners-managers’ level of financial literacy in the context of Pakistan. The findings reveal the complete influence of firm owners- manager’s financial attitude, financial knowledge and financial awareness in adapting financial literacy to upsurge in firm performance. Results indicate that financial awareness and financial knowledge of SME managers are evidently not a precondition to SMEs performance, yet entrepreneur tactics in making decisions and association to financial attitude have a contrast with financial literacy. Findings would be valuable for the SME owners, investors and service providers.
Putting the Plowman in His Place: Order and Genre in the Early Modern Canterbury Tales
Authors: O'Connell Brendan
Published: September 2018

In ca. 1550, the apocryphal Plowman's Tale was moved from the position it occupied in the 1542 edition of Chaucer's Workes, at the end of the Canterbury Tales, to a position between the tales of the Manciple and the Parson. This move represents an early and influential intervention into the order of Chaucer's collection, and had profound consequences for the interpretation of the Canterbury Tales, which were read in this order for hundreds of years. In particular, the placement of the Plowman's debate between the Pelican and the Gryphon established a “Beast Group” among the Canterbury Tales, bringing the apocryphal work into dialogue with the tales of the Nun's Priest and the Manciple, and arguably exerting a considerable influence on the development of political beast fable in the sixteenth century and beyond.

The project was greatly inspired by the Anglo-American “Free libraries” model. This article discusses the implementation of the first “People's Libraries” that functioned as a network, with the support of the Biblioteca de Catalunya. It also describes the establishment of the Escola de Bibliotecàries, a pioneering school of librarianship, which was only open to female students. Finally, it argues that the quality of the current Catalan library system is largely due to the strength of the initial project, which was not abandoned even in the dark times of the two dictatorships in twentieth-century Spain. The uninterrupted operation of a library science school has also played a key role, as it has ensured the training of professionals who have contributed to the continuity of the public library project.
Histórias (in)visíveis: o medo pelo outro como um ato responsável
Authors: Dias Ana Beatriz Ferreira , Miotello Valdemir
Published: September 2018

Ao problematizar relações sociais prejudicadas por danos ligados à prática de ato infracional, analisamos enunciados que circularam em uma prática de justiça restaurativa denominada “Círculo Restaurativo”, uma prática bastante recente no contexto brasileiro. Com foco em enunciados proferidos pela mãe do jovem em conflito com a lei, exploramos a relação que ela estabeleceu com seu filho enquanto uma alteridade que lhe constitui e altera. Para tanto, analisamos a gravação em áudio e vídeo de um círculo restaurativo presente no acervo do projeto gaúcho Justiça para o Século 21. A metodologia de análise fundamenta-se em orientações teórico-metodológicas formulados pelo Círculo de Bakhtin, desenvolvidos de acordo com o paradigma indiciário de leitura e no cotejamento de textos. Observamos que os enunciados da mãe do jovem infrator sugerem um forte medo pelo filho, de tal forma que sua percepção dos fatos a aprisiona em uma responsabilidade ilimitada por ele.

El proyecto de investigación se ha basado en una metodología que expone la actual situación del proceso de facturación que realiza la entidad comercial, mediante el seguimiento de la técnica de la entrevista dirigida al dueño y a sus vendedores. Además, se hizo uso de la técnica de observación para obtener un análisis detallado y claro de los inconvenientes y necesidades que se deben corregir.La librería ABC necesita de una solución, en paralelo a la era digital en la que vivimos. La utilización de un software que administre y registre cada una de las transacciones generadas por sus ventas es de suma importancia no solo porque ayudaría a la microempresa con sus actividades, sino también porque beneficia al equipo de investigación con el estudio de temas tales como ingeniería de software, programación en C# en Visual Studio, programación orientada a objetos y sistemas automatizados para ser aplicados en el proyecto. Por lo tanto, el objetivo de la investigación fue crear un sistema que automatice el proceso de facturación de la librería.Los resultados obtenidos fueron satisfactorios, porque se logró implementar el proyecto y se le dará seguimiento para nuevos requerimientos. Debido a lo anterior, el aprendizaje obtenido fue la mejor ganancia con la investigación realizada.Entorno, junio 2018, número 65: 61-68
Theory of the Trans-ject
Authors: Neyrat Frédéric
Published: September 2018

This chapter considers the problem of thinking singular existences as they are formed from the outside. Existence can only be encountered by the mechanism of the double advance, a dual motion that depends on the relations of existences in an existential field. In a central polyvocal section called “Coalitions,” the concept of the adventurous coalition is proposed to explain the creation of trans-jects, or subjective trajectories, through relation. This chapter also considers the implications of this new atopian trans-ject for both freedom and language. Finally, this chapter takes up the question of the trans-ject in the case of animals: Posing the subject as the repetition of an existential trans-ject, Neyrat argues, offers a way of thinking existence in its multiplicity, unpredictability, and eccentricity.
The Metaphysical Proposition
Authors: Neyrat Frédéric
Published: September 2018

Chapter three examines the construction of philosophical concepts. The chapter offers a defense of the imagination in the formation of metaphysical propositions. Arguing for a return to metaphysics, Neyrat distinguishes philosophy from other disciplines by bringing attention to the out-of-place that drives philosophical thinking. What separates philosophy is its definition as a reflexive practice of atopia. At the same time, the madness of philosophical atopia leads philosophy toward its others: Chapter three concludes by investigating philosophical atopia as it inflects the sciences, art, religion, and politics.
The Denier Outremer
Authors: Stahl Alan M.
Published: September 2018

The most common coin of the eastern realms was the silver denier. Whether on the eastern Mediterranean mainland, in Cyprus, or in Greece, the denier coin-type referred textually to the broader French-speaking world. Much more than a simple imitation, the denier represented a platform on which the eastern principalities could and did add their own distinctive elements.
Western Eyes on the Latin East: The Chronique d’Ernoul et de Bernard le Trésorier and Robert of Clari’s Conquête de Constantinople
Authors: Gaggero Massimiliano
Published: September 2018

We may be able to locate a “cultural center” for the dissemination of the model of Old French prose historiography at the abbey of Corbie. It was at Corbie that two Old French texts associated with events in Outremer, Robert of Clari’s Conquête de Constantinople and the Ernoul-Bernard chronicle, most likely assumed the shape in which we know them today. Both texts ostensibly composed by lay noblemen. Clari’s,Conquête and the Ernoul-Bernard chronicle demonstrate the innovation in form and authorship for French-language texts that we can now increasingly associate with Outremer and the crusades.
A Neglected Relationship: Leontios Makhairas’s Debt to Latin Eastern and French Historiography
Authors: Nicolaou-Konnari Angel
Published: September 2018

Leontios Makhairas’s Recital Concerning the Sweet Land of Cyprus, written in Cypriot Greek, betrays influences from the Old French historiographical traditions of Outremer. This essay explores additional aspects of the creative potential of the frontier zone, a place where the use of Old French highlights the permeability of ethnic and religious boundaries.
Introduction
Authors: De Boever Arne
Published: September 2018

Through discussions of novels by Chuck Palahniuk, Cristina Alger, and Don DeLillo, as well as some films (Fight Club, The Big Short) and television series (Mr. Robot), this chapter lays out the central terms of the book (finance, psychosis, realism) and summarizes the book’s project, as well as the arguments of the individual chapters on Wolfe, Ellis, Harris, Houellebecq, and Lerner. Distinguishing finance from capitalism, the introduction considers the intensified psychotic environment of the digitized finance economy and in particular the realist novel’s place within it. What kind of realism would be attuned to a contemporary economy driven by non-human agents operating at speeds that exceed human and technological observation?
Financing the Novel: Ben Lerner’s 10:04
Authors: De Boever Arne
Published: September 2018

Chapter Six shows how Ben Lerner’s 10:04 is a realist finance novel that takes on the financialization of the novel itself. If Houellebecq in his investigation of finance was mostly focused on art—understandably so, given that the art market obviously exceeds that of literature—Lerner puts the novel at the heart of such a project and delivers a novel that revolves around the promise of the novel: a projected novel, existing on contract, auctioned off for “a strong, six-figure advance” among the New York publishing houses on the basis of a short story that its author published in The New Yorker. The chapter shows that in its focus on the future, Lerner’s novel takes on the topics of capitalism and financialization, asking the difficult questions about the value of a commodity such as the novel and of what the chapter characterizes as a financial instrument such as the novel “on spec.” As a meditation on the future, Lerner’s novel is an investigation into finance and the possibility of a future that would remain outside of the financial logic, or at least operate critically within it.
Necrophilology
Authors: Lezra Jacques
Published: September 2018

This chapter turns to the problem of equivalence posed in Marx's theory of value. It focuses on the ontological contingency at the core of the concept of general equivalence: that because any object, produced by human labor or naturally occurring, may reveal itself over the course of time to be value-carrying, and thus to work like and as a commodity, any object at hand may step, according to laws not given in the object and not given necessarily, into the role of commodity, and thence into the sovereign role of general equivalent. Herman Melville's “Bartleby, the Scrivener,” written from the center of what would become global capital, Wall Street; and Jorge Luis Borges's translation, “Bartleby, el escribiente,” helps to show how this contingent determination shifts the question of abstraction on which Marx's analysis of equivalence turns toward the figure and dynamics of translation.
Adorno and the Humanist Dialectic
Authors: Lezra Jacques
Published: September 2018

This chapter puts in relation what is here referred to as Marx's “dynamic objects” and what Theodor Adorno calls the “dialectical image.” It takes the language of exile—pushed to an extreme philosophical consequence in Adorno's writing—to provide a definitive rearticulation of the notion of “dialectics,” and so too of the way we should understand, today, how objects (conceptual, material) and identities are produced, shaped, valued, and brought into and out of (political, economic) relation. The chapter imagines two ways of approaching the “dialectical image” that is “Adorno,” and hence of sketching out the ways in which the humanist dialectic excludes the specific account of mediation that Adorno, and “Adorno,” provide. Both of them necessarily sit, uneasily, on the mobile border that lies between disciplinary and meta-disciplinary arguments.
Introduction
Authors: Dubilet Alex
Published: September 2018

After analysing how self-emptying has traditionally been construed in theological and philosophical discourses, the introduction argues that recovering the interconnection between immanence and self-emptying fundamentally transforms our conception of both terms. Specifically, it suggests disentangling immanence from its association with the secular world or the human subject. It goes on to lay out the basic elements for a new ethical paradigm of self-emptying, understood through the works of Eckhart, Hegel and Bataille—one that stands in contrast to Levinas’s ethics of the Other and to Foucault’s ethics of self-cultivation. It concludes with a methodological statement arguing for the necessity of reading between historical periods and across traditional disciplinary divides erected between philosophical and theological discourses.
From Estrangement to Entäußerung: Undoing the Unhappy Consciousness in the Phenomenology of Spirit
Authors: Dubilet Alex
Published: September 2018

This chapter argues for the overlooked centrality of Entäußerung, the German translation of the Greek kenosis, in interpreting the Phenomenology of Spirit. By conceptualizing self-emptying as a process that implicates the self-possessed subject as much as all figures of transcendence that may be opposed to that subject, Hegel expands the semantic and conceptual scope of Entäußerung beyond its original Christian theological register. This chapter shows the specificity of the Hegelian imbrication of self-emptying and immanence by contrasting it to the eschatological theories of kenosis and dispossession found in theologians such as Jean-Yves Lacoste. This chapter argue that it is precisely by overlooking Hegel’s novel re-writing of kenosis as an operation that reveals absolute immanence that ungenerous readers have rendered him the consummate thinker of totality and closure. According to such an interpretation, the operation of Entäußerung that culminates and subverts the figure of the Unhappy Consciousness marks not a transition between religion and secular reason, as is it has frequently been read, but the transition from the finite to the speculative perspective, that is, from a perspective that affirms the primacy of finitude to one that affirms only the immanent movement of self-emptying.
Introduction
Authors: Fritsch Matthias , Lynes Philippe , Wood David
Published: September 2018

This chapter serves to introduce the reader to eco-deconstruction and the relevance of Derrida’s thought to environmental philosophy more broadly. After situating eco-deconstruction with respect to environmentally-concerned readings of other continental philosophers such as Husserl, Heidegger, Levinas, Merleau-Ponty, Hans Jonas, Gilles Deleuze, and Félix Guattari, the editors guide the reader’s navigation through the at times perplexing multiplication of related fields, including eco-criticism, eco-phenomenology, posthumanism, new materialism, and more. These examinations are followed by descriptions of the four sections of the book, “diagnosing the present,” “ecologies,” “nuclear and other biodegradabilities,” and “environmental ethics.”
Opening Ethics onto the Other Shore of Another Heading
Authors: McCance Dawne
Published: September 2018

Taking its title from Derrida’s The Other Heading, and focusing on the current water crisis, this paper suggests the need, particularly in ethics, to push off to another shore. Central to the paper is Derrida analysis of what he refers to in “Faith and Knowledge” and The Beast and the Sovereign Volume I as the “double body,” at once corporeal and sublime, that renders human life as “worth more than life,” and that, this chapter argues, impedes the development of a non-speciesist ethics.
