Des périphéries sous influence : l’attraction économique de l’agglomération parisienne, accélérateur du changement social ?
Authors: Desponds Didier , Gatineau Laurent 
Published: April 2018

L’agglomération parisienne renforce son potentiel économique dans les emplois tertiaires à fortes valeurs ajoutées. Conjugué à l’insuffisance de l’offre de logements et au niveau élevé des prix de l’immobilier, ceci contribue à spécialiser socialement les populations résidentes. L’attention se portera ici sur les périphéries proches et lointaines de l’agglomération. Il s’agira à la fois de préciser l’évolution de son aire d’influence et d’évaluer les liens avec le profil social des populations résidentes. Les périphéries, souvent associées à des formes de marginalisation socio-spatiale, enregistrent pourtant des processus de gentrification conduisant à l’éloignement progressif des catégories les plus populaires. Ce mécanisme de tri social en fonction de la distance à l’agglomération a-t-il des conséquences en termes de fragilisation croissante des populations les moins favorisées, en particulier dans un contexte d’augmentation des coûts de l’énergie et de persistance d’un chômage élevé ?
Le travail partagé dans le dispositif « plus de maîtres que de classes » : contrastes des formes de collaboration et des dynamiques professionnelles
Authors: Maleyrot Éric 
Published: April 2018

L’introduction en France, à la rentrée 2013, du dispositif « plus de maîtres que de classes » dans des écoles primaires recevant une majorité d’élèves en difficulté scolaire vise, non seulement, l’amélioration de leurs apprentissages mais également, une collaboration plus forte des enseignants. Par une enquête ethnographique dans trois écoles, cet article cherche à caractériser les formes de collaboration mais également à dégager les dynamiques professionnelles à l’œuvre. En s’appuyant sur les notions de travail partagé et de partenariat, les résultats montrent des formes de collaboration collective qui influencent le travail partagé interindividuel des enseignants. Ils mettent en relief que la reconnaissance professionnelle, les « principes tenus pour vrai » et les termes de la négociation des actions communes constituent trois facteurs influant sur ces collaborations. Enfin, ils révèlent des dynamiques professionnelles agissant de manières diverses sur la forme scolaire traditionnelle.
Le chalandage de traités à l’épreuve des accords d’investissement de nouvelle génération
Authors: Ngo Quoc Chien , Ly Van Anh 
Published: April 2018

Les relations d’investissement entre les États sont souvent envenimées par les manœuvres des investisseurs pour tirer au maximum profit des avantages offerts par les accords d’investissement intergouvernementaux. Le chalandage de traités (emprunté au terme anglais treaty shopping), qui s’inscrit dans cette tendance, désigne une pratique de plus en plus fréquente dans laquelle l’investisseur étranger cherche à acquérir une nationalité « utile » par le changement de domicile ou par la restructuration de ses investissements pour bénéficier de la protection offerte par un traité bilatéral d’investissement (TBI) signé entre un État dont il n’a pas la nationalité et l’État hôte, dans lequel il a investi. Cet article, après un examen de la technique de chalandage de traités et de la jurisprudence arbitrale en matière d’investissements, examine les dispositions prévenant le chalandage dans certains accords de nouvelle génération.
Two-Year Outcome of a Patient Treated With Phototherapeutic Keratectomy and Autologous SMILE Lenticule Transplantation for Flap-Related Complications Following LASIK
Authors: Zhao Jing , Zhao Feng , Huang Jinrong , Xu Haipeng , Chen Yingjun , Zhou Xingtao 
Published: April 2018

PURPOSE:
To describe a patient with flap complications after LASIK who was subsequently treated using phototherapeutic keratectomy (PTK) and an autologous lenticule transplant obtained via small incision lenticule extraction (SMILE).

METHODS:
A 23-year-old man experienced free flap and partial flap loss in the left eye following LASIK, resulting in corneal stroma opacity 1 month later. The manifest refraction was −3.25 diopters sphere (DS)/−0.50 diopters cylinder (DC) × 100° in the right eye and +2.50 DS/−1.25 DC × 155° in the left eye. His left eye was treated with PTK and transplantation of an autologous lenticule obtained from his right eye using the SMILE procedure.

RESULTS:
At the 2-year follow-up visit, the uncorrected distance visual acuity of the left eye had improved from 20/100 to 20/22 and the corrected distance visual acuity had improved from 20/25 to 20/18. Central corneal thickness had increased from 464 to 499 µm. The mean keratometry value had decreased from 45.00 diopters (D) at the 1-month follow-up visit to 39.40 D at the 2-year follow-up visit. Optical coherence tomography examination revealed that the lenticule remained transparent and exhibited a visible demarcation line.

CONCLUSIONS:
The transplantation of an autologous lenticule obtained via SMILE combined with PTK improved uncorrected and corrected acuity in this patient with flap loss after LASIK.

Simulation of the Effect of Different Presbyopia-Correcting Intraocular Lenses With Eyes With Previous Laser Refractive Surgery
Authors: Camps Vicente J. , Miret Juan J. , García Celia , Tolosa Angel , Piñero David P. 
Published: April 2018

PURPOSE:
To simulate the optical performance of three presbyopia-correcting intraocular lenses (IOLs) implanted in eyes with previous laser refractive surgery.

METHODS:
A simulation of the through-focus modulation transfer function (MTF) was performed for three presbyopia-correcting IOLs (Mplus, Oculentis GmbH, Berlin, Germany; Symfony, Johnson & Johnson Vision, Santa Ana, CA; and Mini Well, SIFI S.p.A., Lavinaio, Italy) in one eye with previous myopic LASIK and another with hyperopic LASIK. Real topographic data and the wavefront aberration profile of each IOL obtained with a Hartmann–Shack sensor were used.

RESULTS:
In the eye with myopic LASIK, all IOLs lost optical quality at near and intermediate distances for 4- and 4.7-mm pupil size. For 3-mm pupil size, the Mini Well IOL showed the best intermediate and near MTF and maintained the far focus independently of the pupil. In the eye with hyperopic LASIK, the Mini Well IOL showed an intermediate, distance, and −4.00-diopter (D) foci for all pupils. The Symfony IOL showed a depth of focus at far and intermediate distance for 3-mm and a focus at −2.50 D in the rest. The Mplus showed a focus of −4.50 and −3.00 D for the 3- and 4-mm pupil, respectively.

CONCLUSIONS:
The Mini Well and Symfony IOLs seem to work better than the Mplus IOL in eyes with previous myopic LASIK. With previous hyperopic LASIK, the Mini Well IOL seems to be able to provide acceptable near, intermediate, and far foci for all pupil sizes. These findings should be confirmed in future clinical studies.

Biological Lenticule Implantation for Correction of Hyperopia: An Ex Vivo Study in Human Corneas
Authors: Damgaard Iben Bach , Ivarsen Anders , Hjortdal Jesper 
Published: April 2018

PURPOSE:
To evaluate changes in corneal tomography after stromal lenticule implantation ex vivo, with respect to the dependency of the lenticule thickness and implantation depth on the corneal curvature and the postoperative biomechanical strength at increased chamber pressure.

METHODS:

Twenty-eight human donor corneas underwent pocket implantation of refractive stromal lenticules. Four groups were created by the combination of two implantation depths (110 and 160
µ
m) and two lenticule thicknesses (95
µ
m = 4.00 diopters [D], 150
µ
m = 8.00 D). Sagittal keratometry and total corneal refractive power (TCRP
4mm,apex,zone
) were obtained for the front and back curvature with Pentacam HR (Oculus Optikgeräte GmbH, Wetzlar, Germany) at chamber pressures of 15 and 40 mm Hg.

RESULTS:

The anterior curvature steepening was comparable between the 4.00 D and 8.00 D groups (
P
> .141), but more pronounced with 110
µ
m implantation depth (
P
< .038). The posterior curvature flattened significantly more after implantation of 8.00 D than 4.00 D lenticules (
P
< .002), but was similar at 110 and 160
µ
m implantation depths (
P
> .071). Average ΔTCRP for the 4.00 D and 8.00 D groups was 3.10 ± 0.60 and 5.30 ± 1.66 diopters (D) at 110-
µ
m depth, respectively (
P
= .003), but 1.99 ± 0.79 and 3.36 ± 1.45 D at 160-
µ
m depth, respectively (
P
= .066). The relative correction achieved was 66% to 78% at 110-
µ
m depth and 42% to 50% at 160-
µ
m depth, but similar when using 4.00 D and 8.00 D lenticules. Increased chamber pressure caused significant anterior and posterior curvature steepening after implantation in all four groups (
P
< .001), but not before implantation (
P
> .632).

CONCLUSIONS:
The power of the implanted lenticule must be higher than the intended correction, and customized to the chosen implantation depth. Biomechanical strength seems to decrease after lenticule implantation.

Variation in the Best Fit Sphere Radius of Curvature as a Test to Detect Keratoconus Progression on a Scheimpflug-Based Corneal Tomographer
Authors: Gupta Nishant , Trindade Bruno L. , Hooshmand Joobin , Chan Elsie 
Published: April 2018

PURPOSE:
To evaluate the variation in the best fit sphere radius (BFSR) of curvature on a Scheimpflug corneal tomographer as a test to detect keratoconus progression.

METHODS:
In this retrospective, comparative, case–control study, two groups of eyes with stable or progressive keratoconus were identified based on keratometric, refractive, and visual acuity criteria. Two sequential scans were used to assess the variation in topometric variables. Receiver operating characteristic analysis was conducted for anterior and posterior BFSR values.

RESULTS:

A total of 94 eyes of 62 patients were included in the study; 43 eyes were included in the progressive group and 51 eyes in the stable group. In the progressive group, these differences were found to be statistically significant in sequential scans for the analyzed variables: steepest axis keratometry value (K2) = 1.94 ± 1.70 D (
P
< .001), maximum keratometry value (Kmax) = 2.62 ± 3.08 D (
P
≤ .001), apex pachymetry = 12.233 ± 13.728
µ
m (
P
≤ .001), anterior BFSR = 0.116 ± 0.107 mm (
P
≤ .001) and posterior BFSR = 0.082 ± 0.075 mm (
P
≤ .001). In the stable group, changes in K2, Kmax, apex pachymetry, anterior BFSR, and posterior BFSR were not found to be statistically significant. Analysis of the area under the receiver operating characteristic curve (AUROC) showed that the best tests for discriminating between progressive and stable groups were the variation in the anterior BFSR and variation in K2 (AUROC = 0.940, 95% confidence interval [CI] = 0.884 to 0.996 and AUROC = 0.935, 95% CI = 0.881 to 0.990, respectively). Variation in the posterior BFSR had an AUROC of 0.863 with a 95% CI of 0.775 to 0.950.

CONCLUSIONS:
Steepening of the BFSR of anterior and posterior surface elevation maps could be used as indices for keratoconous progression.

The Relationship Between Mechanical Properties, Ultrastructural Changes, and Intrafibrillar Bond Formation in Corneal UVA/Riboflavin Cross-linking Treatment for Keratoconus
Authors: Chang Shao-Hsuan , Eliasy Ashkan , Chen Kai-Jung , Ji You-Ren , Young Tai-Horng , Wang Tsung-Jen , Willoughby Colin E. , Hamill Kevin J. , Elsheikh Ahmed 
Published: April 2018

PURPOSE:
To determine the relationship between mechanical behavior in cross-linked corneas and changes in the corneal ultrastructure after corneal cross-linking (CXL).

METHODS:
Porcine corneas were treated following the “Dresden” protocol, the current gold standard for clinical treatment, consisting of dropwise application of 0.1% riboflavin in 20% dextran followed by 30 minutes of ultraviolet-A (UVA) irradiation. The effect of CXL was assessed using uniaxial tensile testing, transmission electron microscopy, and Fourier transform infrared spectroscopy, with results compared against corneas treated with each of the treatment solution components individually.

RESULTS:

UVA/riboflavin cross-linked corneas displayed 28% ± 17% increase in the material tangent modulus compared with dextran treatment alone, and altered collagen architecture within the first 300
µ
m of stromal depth consisting of 5% increase in the thickness of collagen fibrils, no significant changes to interfibrillar spacing, and an 8% to 12% decrease in number of fibrils per unit area. Fourier transform infrared spectroscopy confirmed formation of interfibrillar bonds (
P
= .012) induced by UVA-mediated CXL.

CONCLUSIONS:
The data support a model wherein collagen fibril diameter and structural density are fundamental parameters in defining tissue stiffening following UVA/riboflavin CXL and provide benchmarks against which modifications to the Dresden CXL protocol can be evaluated.

« Arrêtez de m’appeler sire !!! ». Les enjeux du refus du pouvoir à travers la fantasy médiévaliste
Authors: Besson Florian 
Published: April 2018

La grande majorité des héros de la fantasy médiévaliste se caractérisent par leur refus du pouvoir : ils fuient leurs responsabilités, abandonnent leurs trônes, se déguisent en chevaliers errants, refusent les titres et les couronnes. Ce motif si souvent répété renvoie en fait à notre malaise face à la violence intrinsèque du pouvoir des seigneurs médiévaux : cette violence, qui sous-tend une domination à la fois politique, économique et symbolique du reste du corps social, semble incompatible avec les représentations contemporaines de l'héroïsme. C'est dès lors l'ensemble de la fantasy qui est comme traversée par ce dilemme : il s'agit de représenter des univers globalement médiévaux tout en mettant en scène des héros qui sont, par leur attitude face au pouvoir et à la violence, des contemporains. Derrière cette question, c'est en fait tout notre propre rapport au pouvoir qui est en jeu
<i>Ubuntu</i> and philoxenia: <i>Ubuntu</i> and Christian worldviews as responses to xenophobia
Authors: Koenane Mojalefa L.J. 
Published: April 2018

Xenophobic attitudes and violence have become regular phenomena in South Africa and other parts of the world. Xenophobia is of great concern not only to South Africans, but also to most developed countries or countries that are considered economically and politically viable by their neighbours, and which offer a safe haven for people who, for whatever reason, are forced to seek refuge elsewhere. Although xenophobia is not unique to South Africa, its most worrying aspect in South Africa is the government’s inability to deal with this evil. The article seeks to challenge South Africa as a dominantly Ubuntu and Judeo-Christian influenced country to fight xenophobia through appealing to Ubuntu values and philoxenia. By Judeo-Christian, I mean religious beliefs and values that are common to both these religions, namely Judaism and Christianity. The article further suggests the ontology that perceives the ‘other’ as an extension of the self. It is argued that South African citizens are collectively responsible for acts of violence against foreign nationals and should thus look for a morally sustainable solution to this evil. The article relies heavily on the work of Kristeva, entitled Strangers to Ourselves, and on the work of Nussbaum, entitled Ubuntu: Reflections of a South African on Our Common Humanity, in Reflections, the Society for Organizational Learning and the Massachusetts Institute of Technology.
‘And God gave Solomon wisdom’: Proficiency in ornithomancy
Authors: Shemesh Abraham O. 
Published: April 2018

The biblical text accords a great deal of attention to King Solomon’s personal abilities and governmental power. Solomon was described as a judge, poet, constructor and the wisest of all people in the Ancient Near East and Egypt. The current study discusses the interpretation of the midrashim that show how Solomon’s wisdom was manifested in his considerable knowledge of ornithomancy, that is, divination using birds, a practice that was considered as an important wisdom in the ancient world because of its practical applications, particularly in the military sphere. It seems that Solomon’s portrayal as a magician is intended and aimed at emphasising his abilities and his impressive character. Moreover, it may have had the purpose of disproving the conception of Solomon as inferior to his surroundings in this respect and the idea that he or his kingdom could be controlled by nations that command this type of wisdom.
El tratamiento del postconflicto colombiano por medio de infografías y visualizaciones de datos
Authors: Marín Ochoa Beatriz Elena 
Published: April 2018

Colombia pasa por un momento histórico especial desde el 26 de septiembre del año 2016, cuando se oficializó ante la sociedad colombiana y ante el mundo la firma de un acuerdo de paz, con tal vez una de las guerrillas más antiguas del mundo, las denominadas Fuerzas Revolucionarias de Colombia, FARC. En ese proceso acelerado para validar lo discutido en la Habana por un largo periodo de tiempo los medios, el gobierno y algunas entidades no gubernamentales implementaron estrategias para dar a conocer los acuerdos de todas las maneras posibles: texto, audio, video, cartillas, informes especiales, multimedias e infografías.La intención de esta ponencia es analizar las formas narrativas y los múltiples discursos empleados, así como el aprovechamiento de herramientas digitales, presentaciones infografías impresas, audiovisuales y digitales; y de visualizaciones de datos, georreferenciaciones y líneas de tiempo que informarán a la sociedad el alcance de lo que se estaba pactando, y que sin ser reduccionista o restarle valor facilitó la comprensión esencial de un documento amplio y extenso como son los acuerdos de paz. Es así como se recuperó el valor de la imagen y sobre todo su característica de síntesis que facilita la interpretación de información y propicia la formación de la ciudadanía, así como se demuestra el gran carácter pedagógico y documental que tiene la infografía y la visualización de datos en el cubrimiento informativo de tal vez el tema más álgido de la agenda mediática colombiana.
Topological n-cells and Hilbert cubes in inverse limits
Authors: Rubin Leonard R. 
Published: April 2018

<p>It has been shown by S. Mardešić that if a compact metrizable space X has dim X ≥ 1 and X is the inverse limit of an inverse sequence of compact triangulated polyhedra with simplicial bonding maps, then X must contain an arc. We are going to prove that if X = (|K<sub>a</sub>|,p<sup>b</sup><sub>a</sub>,(A,)<a href="http://www.codecogs.com/eqnedit.php?latex=\preceq" target="_blank"><img title="\preceq" src="http://latex.codecogs.com/gif.latex?\preceq" alt="" /></a>)is an inverse system in set theory of triangulated polyhedra|K<sub>a</sub>|with simplicial bonding functions p<sup>b</sup><sub>a</sub> and X = lim X, then there exists a uniquely determined sub-inverse system X<sub>X</sub>= (|L<sub>a</sub>|, p<sup>b</sup><sub>a</sub>|L<sub>b</sub>|,(A,<a href="http://www.codecogs.com/eqnedit.php?latex=\preceq" target="_blank"><img title="\preceq" src="http://latex.codecogs.com/gif.latex?\preceq" alt="" /></a>)) of X where for each a, L<sub>a</sub> is a subcomplex of K<sub>a</sub>, each p<sup>b</sup><sub>a</sub>|L<sub>b</sub>|:|L<sub>b</sub>| → |L<sub>a</sub>| is surjective, and lim X<sub>X</sub> = X. We shall use this to generalize the Mardešić result by characterizing when the inverse limit of an inverse sequence of triangulated polyhedra with simplicial bonding maps must contain a topological n-cell and do the same in the case of an inverse system of finite triangulated polyhedra with simplicial bonding maps. We shall also characterize when the inverse limit of an inverse sequence of triangulated polyhedra with simplicial bonding maps must contain an embedded copy of the Hilbert cube. In each of the above settings, all the polyhedra have the weak topology or all have the metric topology(these topologies being identical when the polyhedra are finite).</p>
