International Accreditation: Are We There Yet?
Authors: Steve O. Michael 
Published: June 2015

With the increasing internationalization of higher education and the explosion in the number of students and faculty studying, researching, and teaching outside of their home countries, global standards for educational quality control have become an imperative. The most effective approach to quality control within institutions of higher education, the paper argues, is voluntary accreditation — periodic internal reviews that are externally validated. Accreditation is a uniquely American creation, but it is gaining currency in other countries as well. The paper discusses the potential benefits of international accreditation, which would facilitate collaboration between accredited universities located in different countries. The practice of accreditation is contrasted with the practice of ranking, which is presented as a commercial exercise that does a poor job of measuring the actual institutional quality and that is ultimately based on the personal opinions of the people doing the ranking. Finally, the potential challenges that international accreditation faces (including unwillingness of the creators of the current quality industry to yield power to a global ccreditation agency, among other things) are presented as temporary obstacles.
Balados sur les stratégies d’écoute et de prise de notes pour les étudiants d’immersion en français au niveau universitaire : de la conception à l’évaluation des impacts
Authors: Knoerr Hélène , Weinberg Alysse 
Published: June 2015

Plusieurs études ont suggéré la baladodiffusion comme outil pédagogique pour améliorer les compétences d’écoute en langue seconde (L2) au niveau universitaire. cette optique, nous avons développé une série de sept balados ancrés dans la théorie métacognitive et la théorie de l’écoute en langue étrangère présentent des stratégies d’écoute en L2 et des techniques de prise de notes. Ces balados ont été proposés à 161 étudiants inscrits dans 21 classes du Régime d’immersion en français de l’Université d’Ottawa. Nous avons ensuite mesuré leur impact sur les stratégies d’écoute et de prise de notes des étudiants. Les résultats sont mitigés, avec certaines améliorations plus ou moins significatives sur le plan quantitatif, et d’autres plus marquées sur le plan qualitatif.
Resolution of precocious puberty following resection of fourth ventricular medulloblastoma: case report

Published: June 2015

Medulloblastoma is a malignant embryonal tumor that arises in the cerebellum and invades the fourth ventricle, often resulting in obstructive hydrocephalus. Patients typically present with symptoms related to increased intracranial pressure and cerebellar dysfunction. The authors report a rare case of classic medulloblastoma with central precocious puberty (CPP) as its only presenting symptom.
A 7-year-old boy with no prior history of medulloblastoma presented with Tanner Stage IV testicular enlargement and a 4-month history of acne and pubic hair. Laboratory tests of blood samples demonstrated highly elevated luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone. Admission MRI of the brain revealed a mass in the posterior fossa, which bordered and compressed the fourth ventricle. The patient also exhibited mild lateral and third ventriculomegaly. Surgical options were discussed with the neurosurgical department.
A suboccipital craniotomy and C-1 laminectomy were performed. A large mass was seen arising from the inferior surface of the vermis, and lying within the fourth ventricle. Gross-total microsurgical resection of the mass was performed. Histopathological investigation characterized the tumor as classic medulloblastoma. Follow-up laboratory tests of blood samples demonstrated a reduction of LH, FSH, and testosterone back to prepubertal levels. The patient then began radiation and chemotherapy.
This report demonstrates that mild obstructive hydrocephalus due to a posterior fossa tumor may present with unexpected symptoms, such as CPP. To the authors’ knowledge, precocious puberty has not yet been associated with medulloblastoma, although it has been found with other posterior fossa tumors. Extensive imaging of the CNS for patients presenting with CPP is recommended.
Modelés karstiques, circulation souterraine et alimentation des lacs à sédimentation carbonatée du Bassin de Taoudenni, Sahara Malien (Karst forms, underground circulation and feeding of the lakes with carbonate deposits of the basin of Taoudenni, malian Sahara)
Authors: Riser Jean 
Published: June 2015

Abstract. - The lake basin of Taoudenni presents two principal holocene lakes, the one is salted (Taoudenni) the second is carbonated (Haijad).
The complexity of the aquifers and the presence of geological calcareous and evaporitic series explain these differences.
The carbonate deposits of the Haijad lake (8300 BP-4500 BP) show that it is feed by karst springs. On the back slope of the namurian limestones some karst forms are observed : lapiez, dolines, dry valleys. An aquifer feed come to the Hoggar, across the Tanezrouft seems very problematic.
Les hymnes dans le discours méthodiste
Authors: Van Noppen Jean-Pierre 
Published: June 2015

L’approche « pragmastylistique » des hymnes wesleyens relève d’une étude plus vaste, qui cherche à exonérer le discours méthodiste des accusations de manipulation de la masse ouvrière par le biais de la religion (répétition lexicale, imagerie perverse, induction à l’hypnose ou hystérie collective). Les hymnes que le méthodisme a littéralement produits par milliers ont « donné des ailes aux doctrines du Réveil » (J. E. Rattenbury) et assuré au message méthodiste un impact à la fois émotif et mnémonique étonnant, quel que fût le degré d’illettrisme des audiences ciblées. Jean-Pierre van Noppen * montre que ces hymnes ont disséminé un message d’espoir et d’amour avec plus d’efficacité que tout autre medium. Une analyse statistico-lexicale révèle que les accusations formulées par le camp marxiste sont basées le plus souvent sur des faits isolés, qui n’étaient ni aussi systématiquement combinés, ni aussi représentatifs du discours méthodiste que les critiques ne voudraient le faire croire.
La naissance en mutation, un enjeu pour la sociologie ?
Authors: Clavandier Gaëlle , Charrier Philippe 
Published: June 2015

Les naissances n’ont plus vocation à « perpétuer un monde immobile ». Elles s’inscrivent dans un monde ouvert, un environnement fait d’incertitudes et de désirs. Au-delà des mutations démographiques et de la politique en matière de natalité en France qui interviennent à une échelle macro, deux mouvements antinomiques à bien des égards ont contribué à façonner « la naissance ». La médicalisation qui a pour corollaire une professionnalisation de l’accompagnement et une organisation établie sur le modèle du risque obstétrical, inscrit la naissance dans des dispositifs prescrits faisant de la parturiente essentiellement une patiente. Cette administration des naissances, assimilable à un biopouvoir, peine aujourd’hui à instituer car elle tend à réduire la naissance au suivi de grossesse, puis à l’accouchement, alors que les parents l’inscrivent dans un tout autre régime de temporalité. Donner naissance est un événement, qui s’initie par un projet jusqu’à l’expérience de la parentalité. Cette valorisation de l’intime va de pair avec un rapport authentique à l’enfant. Article de synthèse, ce texte vise à identifier les enjeux relatifs à la naissance et au naître en déplaçant le curseur d’études empiriques, vers une perspective plus globale. Étudier l’entrée des individus dans la vie, ce qui fait l’existence d’un être humain reconnu socialement, pourrait être le principal objectif des travaux à venir.
Valorisation des « compétences parentales » et contrôle des risques dans l’accompagnement des parents : les ambivalences de la « contractualisation » en protection de l’enfance
Authors: Lacroix Isabelle 
Published: June 2015

Dans un contexte législatif qui promeut le droit des usagers, cet article analyse le travail socio-éducatif de professionnelles auprès de parents, au sein de mesures dites « contractuelles » en protection de l’enfance. Il s’appuie sur un travail empirique qui croise entretiens collectifs et individuels auprès d’assistantes sociales, de cadres associatifs, d’éducatrices, de psychologues de dix dispositifs et de quelques parents. Le recueil d’archives et l’observation du travail d’inspectrices de l’Aide sociale à l’enfance (ASE) complètent ces données. Nous mettons en lumière combien les normes et activités de ces professionnelles sont transformées par les logiques à l’œuvre dans l’action publique de « soutien à la parentalité ». Dans un second temps, nous montrons que la forte implication parentale demandée dans ce type de mesures rencontre des limites avec certains parents. Ce mouvement de contractualisation dans le champ de la protection de l’enfance témoigne de l’évolution des modalités de l’intervention sociale où l’idéologie de la responsabilisation individuelle est prégnante.
Surprising judgments about robot drivers: Experiments on rising expectations and blaming humans
Authors: Danielson Peter 
Published: June 2015

N-Reasons is an experimental Internet survey platform designed to enhance public participation in applied ethics and policy. N-Reasons encourages individuals to generate reasons to support their judgments, and groups to converge on a common set of reasons pro and con various issues. In the Robot Ethics Survey some of the reasons contributed surprising judgments about autonomous machines. Presented with a version of the trolley problem with an autonomous train as the agent, participants gave unexpected answers, revealing high expectations for the autonomous machine and shifting blame from the automated device to the humans in the scenario. Further experiments with a standard pair of human-only trolley problems refine these results. While showing the high expectations even when no autonomous machine is involved, human bystanders are only blamed in the machine case. A third experiment explicitly aimed at responsibility for driverless cars confirms our findings about shifting blame in the case of autonomous machine agents. We conclude methodologically that both results point to the power of an experimental survey based approach to public participation to explore surprising assumptions and judgments in applied ethics. However, both results also support using caution when interpreting survey results in ethics, demonstrating the importance of qualitative data to provide further context for evaluating judgments revealed by surveys. On the ethics side, the result about shifting blame to humans interacting with autonomous machines suggests caution about the unintended consequences of intuitive principles requiring human responsibility.
HINDU BELIEFS AND THE MARITIME NETWORK IN SOUTHERN VIETNAM DURING THE EARLY COMMON ERA
Authors: Le Lien Thi 
Published: June 2015

In recent decades a large number of artifacts related to Hindu belief have been discovered in southern Vietnam. They have been found in various types of archaeological sites and clearly played different functions in the religious beliefs and daily lives of the people who created them. These valuable archaeological sources provide interesting information on the penetration of Hinduism into the area. This essay will address the following subjects: The distribution of these artifacts and the sites where they have been found; their connection to Hindu beliefs and their illustration of styles of Hindu art; and the role of maritime networks of trade in the development of Hindu beliefs during the state formation period in Southern Vietnam.

AbstractSediment records of the stable isotopic composition of N (δ15N) show light δ15N values at several sites in the proto‐North Atlantic during Oceanic Anoxic Event 2 (OAE 2) at the Cenomanian‐Turonian transition (∼94 Ma). The low δ15N during the event is generally attributed to an increase in N2 fixation and incomplete uptake of
for phytoplankton growth. A compilation of all reliable data for the proto‐North Atlantic during OAE 2 demonstrates that the most pronounced negative shift in δ15N from pre‐OAE 2 to OAE 2 occurs in the open ocean but with δ15N never lower than −3‰. Using a box model of N cycling for the proto‐North Atlantic during OAE 2, we show that N2 fixation is a major contributor to the δ15N signal, especially in the open ocean. Incomplete uptake of
for phytoplankton growth is important in regions dominated by downwelling, with lateral transport of
acting as a major source. In the southern proto‐North Atlantic, where bottom waters were euxinic, the light δ15N signature is largely explained by upwelling of
. Our study provides an overview of regional differences in δ15N in the proto‐North Atlantic and highlights the role of lateral exchange of water and nutrients, in addition to local biogeochemical processes, in determining δ15N values of OAE 2 sediments.

A three‐dimensional computational fluid dynamics model of shear stress distribution during neotissue growth in a perfusion bioreactor
Authors: Guyot Y. , Luyten F.P. , Schrooten J. , Papantoniou I. , Geris L. 
Published: June 2015

ABSTRACTBone tissue engineering strategies use flow through perfusion bioreactors to apply mechanical stimuli to cells seeded on porous scaffolds. Cells grow on the scaffold surface but also by bridging the scaffold pores leading a fully filled scaffold following the scaffold's geometric characteristics. Current computational fluid dynamic approaches for tissue engineering bioreactor systems have been mostly carried out for empty scaffolds. The effect of 3D cell growth and extracellular matrix formation (termed in this study as neotissue growth), on its surrounding fluid flow field is a challenge yet to be tackled. In this work a combined approach was followed linking curvature driven cell growth to fluid dynamics modeling. The level‐set method (LSM) was employed to capture neotissue growth driven by curvature, while the Stokes and Darcy equations, combined in the Brinkman equation, provided information regarding the distribution of the shear stress profile at the neotissue/medium interface and within the neotissue itself during growth. The neotissue was assumed to be micro‐porous allowing flow through its structure while at the same time allowing the simulation of complete scaffold filling without numerical convergence issues. The results show a significant difference in the amplitude of shear stress for cells located within the micro‐porous neo‐tissue or at the neotissue/medium interface, demonstrating the importance of taking along the neotissue in the calculation of the mechanical stimulation of cells during culture.The presented computational framework is used on different scaffold pore geometries demonstrating its potential to be used a design as tool for scaffold architecture taking into account the growing neotissue.

Automated and Continuous Production of Microstructured Metallic Plates via Cold Embossing
Authors: Wiborg Ole , O'Connell Martin , Thiele Richard , Wichert Martin , Kolb Gunther 
Published: June 2015

AbstractMany critical issues need to be addressed when microstructured reactors are manufactured in large unit volumes. The most crucial of these are cost, ease of production, and reliability. The lack of breakthrough manufacturing technology to provide high‐efficiency, low‐cost, high‐precision plates is a hindrance to the early market implementation of systems requiring metallic microstructured plates. This contribution focuses on the development and optimization of a combined embossing and bending tool for the quick and continuous manufacture of easily machined plates.
Succinic Acid Production in Fed‐Batch Fermentation of Anaerobiospirillum succiniciproducens Using Glycerol as Carbon Source
Authors: Bretz Karlheinz 
Published: June 2015

AbstractConsidering glycerol as an inexpensive alternative carbon source, the optimal glycerol concentration for succinic acid production with Anaerobiospirillum succiniciproducens was identified in shake‐flask trials. The addition of a defined amount of glucose improved the growth and succinic acid productivity significantly. In fed‐batch processes with glycerol as sole substrate, a maximum succinic acid concentration and product substrate yield were obtained. The addition of glucose led to a 2.5‐fold increased succinic acid concentration whereas the product substrate yield remained nearly constant.

AbstractThe tridentate chelate nickel complexes [(CO)Ni{(PPh2CH2)3CMe}] (2), [(CO)Ni{(PPh2CH2CH2)3SiMe}] (6), and [Ph3PNi{(PPh2CH2CH2)3SiMe}] (7), as well as the bidentate complex [(CO)2Ni{(PPh2CH2)2CMeCH2PPh2}] (3) and the heterobimetallic complex [(CO)2Ni{(PPh2CH2)2CMeCH2Ph2PAuCl}] (4), have been synthesized and fully characterized in solution. All 1H and 13C NMR signal assignments are based on 2D‐NMR methods. Single crystal X‐ray structures have been obtained for all complexes. Their 31P CP/MAS (cross polarization with magic angle spinning) NMR spectra have been recorded and the isotropic lines identified. The signals were assigned with the help of their chemical shift anisotropy (CSA) data. All complexes have been tested regarding their catalytic activity for the cyclotrimerization of phenylacetylene. Whereas complexes 2–4 display low catalytic activity, complex 7 leads to quantitative conversion of the substrate within four hours and is highly selective throughout the catalytic reaction.
A Visible‐Light‐Induced α‐H Chlorination of Alkylarenes with Inorganic Chloride under NanoAg@AgCl
Authors: Liu Shouxin , Zhang Qi , Li Huiying , Yang Yihua , Tian Xia , Whiting Andrew 
Published: June 2015

AbstractAn efficient, photocatalytic chlorination of alkylarene α‐H groups using NaCl/HCl as a chlorine source has been developed, which involves a radical mechanism under visible‐light (including sunlight) conditions. A chlorine radical is proposed to be formed by an electron transfer from chloride ion to O2 in air through the bandgap hole of the semiconductor AgCl. The chlorination protocol is characterized by its use of natural sunlight or other visible light, mild conditions, cheap source of chlorine, green solvent, and high selectivity. The yield of benzylchloride is 95 % with a toluene conversion as high as 40 %, which rivals traditional chlorination methods.
Severe and Enduring Anorexia Nervosa (SEED‐AN): A Qualitative Study of Patients with 20+ Years of Anorexia Nervosa

Published: June 2015

AbstractLittle is known about how patients with long‐term eating disorders manage their clinical problems. We carried out a preliminary qualitative study (using Thematic Analysis) of patients with severe and enduring anorexia nervosa (SEED‐AN) in which we undertook recorded interviews in eight participants whose conditions had lasted 20–40 years. We found 15 principle features in physical, psychological, social, family, occupational and treatment realms. Psychological and social realms were most affected. Severe physical problems were reported. They described feelings of unworthiness, frugality regarding money and obsessive time‐keeping. Persisting with negligible social networks, participants described depression and hopelessness, while somehow achieving a sense of pride at their endurance and survival in spite of the eating disorder. They emphasized the importance of professional help in managing their care. The severe and enduring description, often reserved for people with psychotic illness, is appropriately applied to SEED‐AN, which has major impacts in all realms.

Internal phosphorus load in a Mexican reservoir: Forecast and validation
Authors: Hansen Anne M. , Márquez-Pacheco Henri 
Published: June 2015

Abstract

To determine the internal phosphorus load (IPL) as a function of redox potential (Eh) in a Mexican reservoir, the results from a phosphorus (P) release experiment were extrapolated to temporal and spatial variations of Eh in sediments, and an IPL-Eh of 24.2 ± 2.5 t/yr was obtained. This result is compared with the P mass balance (MB) in the reservoir, where the IPL-MB is determined as the difference between P inputs to the reservoir and the outputs. Inputs of P are the sum of the external P load from the hydrological basin, the IPL, and P in atmospheric precipitation; outputs of P are the sum of sedimented P, and the removal of P in water and biomass, and the resulting IPL-MB, is 26.4 ± 4.9 t/yr. In addition, P concentrations in sediment cores (SCs) are analyzed, and the historical release of P from sediments determined, resulting in an IPL-SC of 23.5 ± 1.4 t/yr. The different IPL results are similar, as average values are within the standard deviation of IPL-MB. It is concluded that analysis of the variations in Eh in sediments allows determination of the reservoir's IPL. Six-weekly IPL-Eh and IPL-MB values are analyzed, and it can be seen that IPL occurs mainly during the period from May to August, when the water column is thermally stratified.

The Utility of Ultrasound for Diagnosing Purulent Infections of the Upper Extremity
Authors: Halim Andrea , Shih Yushane , Dodds Seth D. 
Published: June 2015

Background The purpose of this study was to determine the test characteristics of formal ultrasound when used to diagnose upper extremity soft tissue abscess in the setting of suspected infection. Methods We completed a retrospective chart review of all patients who had formal ultrasounds at our institution for the indication of diagnosing upper extremity abscess between July 2010 and July 2013. Using presence of purulence as the gold standard for diagnosis of abscess, we calculated the test characteristics of ultrasound. We then performed a series of logistic regression models with ultrasound being the independent variable of interest. Results Using search criteria consistent with upper extremity abscess, we identified 512 patients who underwent ultrasound examinations during our study period. Of these, 178 met the enrollment criteria. Ultrasound reports revealed 110 negative findings, 37 definitively positive findings, and 31 ambiguous findings. Forty-four patients had a final diagnosis of abscess, and 15 of these patients had negative or ambiguous ultrasounds. The sensitivity of definitively positive ultrasound was 65.9 %. The specificity was 94.0 %. Positive predictive value (PPV) of a definitively positive ultrasound result was 78.4 %, and negative predictive value (NPV) of a definitively negative result was 90 %. Logistic regression demonstrated a statistically significant association between definitively positive ultrasound and abscess, but no association between ambiguous ultrasound and abscess after adjustment for significant covariates. Conclusions Ultrasound is not a sensitive method to detect the presence of abscess in the setting of upper extremity infection. However, in this population of patients with suspected abscess, the negative predictive value was high with and without the inclusion of ambiguous results, suggesting reasonable utility of ultrasound as a rule-out test.
