Published: February 2015

Ce recueil d’hommages à Germaine Leman-Delerive a généré un travail collectif lié à la céramique de la fin du premier et début du second Âge du Fer (Hallstatt D – LT A1) dans les départements du Nord, du Pas-de-Calais et de la Somme. Le but est de proposer un premier bilan documentaire sur la typochronologie des mobiliers domestiques. L’étude comparative d’ensembles, appuyée par un outil de sériation et les indications fournies par les mobiliers associés et/ou les datations radiocarbones, permet de proposer une première trame d’évolution en quatre étapes, mises en correspondance de manière encore imprécise avec la fin du Hallstatt ancien et/ou le début du Hallstatt moyen (Hallstatt C2/D1), le Hallstatt moyen, voire le début du Hallstatt final (Ha D1/2), le Hallstatt final jusqu’à la transition avec La Tène ancienne (Hallstatt D2-D3) et enfin le début de La Tène ancienne (La Tène A1). Le renouvellement du répertoire est progressif, sans rupture significative, avec un registre morphologique fortement marqué par la carène depuis le début du Hallstatt D. L’appréhension des faciès régionaux se heurte aux vides documentaires et au peu d’information disponible pour la partie littorale de la zone d’étude. Des pistes de réflexion et un scénario évolutif sont toutefois dégagés. L’existence de deux faciès initiaux de part et d’autre de la vallée de l’Escaut tend à s’atténuer au cours du Hallstatt final, avec l’émergence d’un faciès régional « picard », qui va lui-même converger vers les répertoires du domaine Aisne-Marne de la fin du Hallstatt final, jusqu’à s’y confondre davantage au début de La Tène ancienne.

Engaging Students through Blogs: Using Blogs to Boost a Course Experience
Authors: Shana Zuhrieh A , Abulibdeh Enas S 
Published: February 2015

Globalization is irreversible and the Internet is increasingly used to connect people and share information worldwide. The proliferation of digital information allows us to make choices about how we gather information and use technology to enhance learning. This is especially true in an academic environment, where the Internet is often used as a tool to facilitate deeper learning.
The focus of this study is to investigate whether and how to use blogs to boost student learning in a traditional learning environment where lecture based (didactic) instructional practices still prevailing. This paper will also look at Al-Ain University of Science and Technology (AAU) student perceptions of the benefits of blogs for enhancing college learning.
To explore these issues, Blogging was introduced to students in the Internet Technology class. A combination of one hundred and ninety-nine graduate and undergraduate AAU students answered an online questionnaire exploring their perceptions of blogs as a learning tool. Quantitative and qualitative data was also collected through open-ended questionnaires, student journals and reports, and end-of-class e-portfolios.
All statistical analyses were carried out with SPSS. Results indicate that blogs have the potential to empower and enhance student learning. Student response to using blogs in the course has been overwhelmingly positive.
Guidelines for the marketing of independent schools in South Africa
Authors: Immelman Reaan , Roberts-Lombard Mornay 
Published: February 2015

Objective: The primary objective of the study is to recommend marketing guidelines for independent primary schools, with the focus on product and people in the marketing mix. This objective was achieved by identifying choice factors influencing parents’ selection of independent primary schools, identifying the most important choice factors and demographic differences regarding the importance parents attached to these factors.Problem investigated: Some independent schools in South Africa find it difficult to market themselves effectively as a result of a lack of information pertaining to the choice factors identified by parents when selecting independent primary schools. A comprehensive set of choice factors will provide a more accurate picture of the criteria parents perceive as important in independent school selection.Methodology: The methodological approach followed was exploratory and quantitative in nature. The sample consisted of 669 respondents from 30 independent schools in Gauteng in South Africa. A structured questionnaire, with a five-point Likert scale, was fielded to gather the data. The descriptive and factor analysis approaches were used to analyse the results.Findings and implications: The main finding is that a total of 29 different choice factors were identified that parents perceive as important when selecting an independent primary school. The most important factor for parents when making a choice is the small size of the classes, followed by the religious ethos of the school as well as qualified and committed educators. This indicates that parents have a comprehensive set of choice factors and implies that a better understanding of these factors by independent schools may assist them to focus their marketing efforts more optimally in order to attract new learners.Originality and value of the research: Very little research exists with specific reference to independent school marketing in South Africa. The importance of the research study at hand stems from the fact that some parents are dissatisfied with the public schools system, stimulating the demand for independent schools in the country. The increased level of competition amongst independent schools in South Africa therefore necessitates that these schools gain knowledge on the choice factors of parents when selecting such a school. This will assist independent primary schools in the development and design of their individual marketing strategies when recruiting new learners.

An Ounce of Prevention is Worth a Pound of Cure: Ergonomics in Dental Practice
Authors: Ramdurg Praveenkumar , Mendigeri Vijaylaxmi , Puranik Surekha 
Published: February 2015

ABSTRACT
Dentists and dental hygienists are at risk for work-related musculoskeletal disorders compared to the general population. The most frequent injuries occur in the spine (neck and back), shoulders, elbows and hands. While specific procedures place the clinician at increased risk for finger and hand injuries, poor posture is a risk factor with all procedures. Sitting in an appropriate chair, using magnification for visualization, and the selection of ergonomically-friendly equipment are essential for the health of dental clinicians. Ergonomics is the science of designing jobs, equipment and workplaces to fit workers. Proper ergonomics design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long term disability. This article includes musculoskeletal disorders (MSDs) and the signs, symptoms and risk factors of these types of injuries, so that one can be aware of developing problems and can change his /her approach to work or alter the workstation setup to prevent further injury. The article discusses the applications of ergonomics in dental clinic set up and offers different exercises to work with comfort, efficiency and ease.

Dissociation of Shaft of Humerus from Head in Threepart Fracture Dislocation due to Stress Concentration at Intramedullary Nail End
Authors: Dhillon Mandeep , Kumar Vishal , Chouhan Devendra , Kothari Manish Kundanmal 
Published: February 2015

ABSTRACT
A three-part fracture dislocation of the proximal humerus usually dissociates from the shaft at the level of the surgical neck or the anatomical neck. Dissociation from the shaft below this level has not reported in the literature before. Here we describe the injury of a middle aged patient with a three-part fracture dislocation of the humerus with dissociation of the head from the shaft at the level of proximal shaft humerus with a 25 years old Rush nail in situ. The dislocated head was found abutting the thoracic wall. This case report highlights the effect of stress concentration at intramedullary nail ends in the upper limb as well as the need for an extended approach when the dislocated head appears close to the thoracic wall.

Malignant Glaucoma-Like Syndrome after EX-PRESS Filtration Surgery
Authors: Casini Giamberto , Loiudice Pasquale , Martinelli Paolo , Nasini Francesco , Nardi Marco 
Published: February 2015

Purpose To report a case of postsurgical shallow anterior chamber and elevated intraocular pressure (IOP) simulating malignant glaucoma. Methods A 20-year-old woman underwent EX-PRESS® device implant for treatment of primary open-angle glaucoma. Results Postoperative examination showed a shallow anterior chamber, the EX-PRESS® device embedded in the iris, an IOP of 28 mm Hg, and an annular detachment of the choroid ciliary body, suggesting hyperfiltration followed by EX-PRESS® blockage. The anterior chamber was restored using an ophthalmic viscoelastic and an additional suture was applied ensuring the scleral flap. The IOP progressively decreased in the following days and the anterior chamber remained deep and stable. New ocular ultrasonography showed complete resolution of the ciliary body detachment 15 days after surgery. Conclusions After glaucoma surgery, not every patient with shallow anterior chamber and normal or high IOP necessarily has a ciliary block glaucoma. In our case, hyperfiltration led to choroidal expansion, shallow anterior chamber, obstruction of the EX-PRESS®, and secondary blockage of outflow. The differential diagnosis is important in order to avoid further invasive procedures (i.e., lensectomy or vitrectomy).
“Becoming a Part of Her Innermost Being”: Gender, Mass-Production, and the Evolution of Department Store Culture in Edith Wharton’s “Bunner Sisters”
Authors: BOYLE ELIZABETH A. 
Published: February 2015

Abstract
Written in 1892 and published in her 1916 collection of short stories entitled Xingu, Edith Wharton’s “Bunner Sisters” offers a uniquely literary perspective into an era of change in New York City’s production and commerce history. Strategically set in the 1870s, “Bunner Sisters” supplies readers with a critical commentary on the United States’ economic transition from neighborhood shops selling hand-made products to large department stores selling mass-produced, machine-made wares. Wharton locates Bunner Sisters, one of these small neighborhood retailers, in what Gary Totten refers to as “an outpost of the Ladies’ Mile bordering Stuyvesant Square”1 or, according to Wharton, a “side-street already doomed to decline.”2 Indeed, while displacing smaller neighborhood shops like Bunner Sisters, large department stores like Macy’s helped to reconfigure existing retail and consumption practices by drawing shoppers out of close-knit, familial shopping communities and welcoming them into the anonymity of the department store. Drawing from contemporary “separate spheres” ideology,3 Wharton links these economic transformations with an array of social implications, ultimately revealing how changes in manufacturing and retail practices also affect society’s attitudes towards consumption and interactions with consumable products. To these ends, Wharton repositions contemporary definitions of “public space” as an arena in which sociopolitical interactions take place, and instead characterizes it as a space where mass-produced, factory goods are made and retailed. In a similar way, she acknowledges contemporary characterizations of “private” spaces as domestic environments but also reconfigures them as the neighborhood shops and producers of pre-industrial, handmade objects.
Catalytic Asymmetric Ketene [2 + 2] and [4 + 2] Cycloadditions
Authors: G. Nelson Scott , D. Dura Robert , J. Peelen Timothy 
Published: February 2015

AbstractKetenes are among the few synthetic building blocks that undergo facile thermal [2 + 2] and [4 + 2] cycloadditions, yielding cyclobutanes, β‐lactones, β‐lactams, dioxins, quinoxalines, thiazinones, pyranones, and other useful carbo‐ and heterocycles. In addition to substrate structure, the presence of Lewis acids and bases can have a decisive effect on product outcome by diverting ketene reactivity to different cycloaddition manifolds.This comprehensive review focuses on catalyzed enantioselective ketene [2 + 2] and [4 + 2] cycloadditions in which the asymmetric induction is derived solely from the catalyst complex. Accordingly, diastereoselective cycloadditions are described only when they are relevant to a catalytic asymmetric reaction variant. Molecular orbital interactions are correlated to the electronic structure of ketenes and used to explain ketene reaction pathways.Cinchonaalkaloids play an important role in Lewis base catalyzed asymmetric carbonyl and imine cycloadditions, whereas Al(III)‐, Fe(II)‐, Ti(IV)‐, and Cu(II)‐complexes are mainly responsible for Lewis acid catalyzed asymmetric transformations. Carbene catalysts are also significant for both ketene–carbonyl and ketene–imine cycloadditions.The subject cycloaddition protocol is also compared with other methods, including Mannich‐ and aldol‐based approaches to β‐lactams and β‐lactones, nitrone–alkyne and hetero Diels–Alder reactions, and the catalytic asymmetric allylation–lactonization.
Magnetic reconnection in the auroral acceleration region
Authors: Chaston C. C. 
Published: February 2015

AbstractEvidence is presented for the operation of extreme guide field magnetic reconnection in the presence of sheared flows in a narrow current sheet through the auroral acceleration region. Using auroral imagery, magnetically conjugate particle measurements and a 3‐D reduced MHD simulation, vortical motions in a narrow, rapidly evolving auroral arc indicative of the operation of magnetic tearing are identified. An estimate of the contribution of this process to the observed rate of energy deposition at the ionosphere shows that while this contribution can be significant it remains a minor fraction of the total. These observations are placed in the context of low magnetic shear reconnection made possible in plasmas with low plasma beta.
Slow electron phase space holes: Magnetotail observations
Authors: Norgren C. , André M. , Vaivads A. , Khotyaintsev Y. V. 
Published: February 2015

AbstractWe report multispacecraft observations of slow electrostatic solitary waves in the plasma sheet boundary layer. The electrostatic solitary waves are embedded in a region with field‐aligned electron flows and are interpreted as electron phase space holes. We make unambiguous velocity and length estimates of the electron holes, vEH∼500 km/s and l||∼2–4λDe, where l|| is the parallel half width. We do not detect any magnetic signature of the holes. The electrostatic potentials of the holes are of the order eϕ/kBTe∼10%, indicating that they can affect electron motion and further couple the electron and ion dynamics.

Published: February 2015

AbstractWe present the efficient synthesis and photovoltaic response of a linearly conjugated molecule DT‐DPP (AAnAT)2, which contains a dithienyldiketopyrrolopyrrole core symmetrically connected through a 9,10‐anthracenyl unit to 3‐alkylthiophene via an acetylene linkage. The compound is crystalline with a Tm of 204 °C. The as‐cast film has a main broad absorption at 650 nm with a shoulder at 737 nm, tailing until ca. 800 nm. The HOMO level was estimated as −5.26 eV, derived from the first reversible electron oxidation wave at ca. 0.93 V vs. Ag/AgCl reference electrode. The space charge limited current hole mobility of a pristine film is ca. 2.90×10−4 cm2 V−1 s−1. The preliminary characterization of simple bulk heterojunction solar cells provides a power conversion efficiency (PCE) of ca. 4.0 % with VOC=0.77 V, JSC=10.0 mA cm−2, and FF=52 %, based on the as‐cast active layer without a processing additive or solvent vapor annealing. Thermal annealing the active layer at a mild temperature of 50 °C increased the PCE to 4.39 % due mainly to the improvement of the FF.

Published: February 2015

BackgroundUse of muscle grafts for hemostasis during surgery has re‐emerged; recent animal model studies have shown effective bleeding control with their use. However, the mechanism of action is unknown. The aim of this study is to evaluate the action of muscle extracts on the coagulation pathways and platelet aggregation.MethodsMuscle extracts were prepared by dissolving crushed snap‐frozen muscle tissue (0.04 to 0.8 mg) in 1 mL saline. Saline was used as control. Prothrombin time, activated partial thromboplastin time (APTT), thrombin time, and platelet aggregation studies were performed on both muscle extract and saline. Prothrombin time and APTT were repeated using factor VII–deficient plasma, factor X–deficient plasma, lupus plasma, and contact pathway–inhibited plasma. Mean readings in the muscle group and control group were compared using nonparametric Mann‐Whitney U test (Wilcoxon rank sum test with continuity correction).ResultsAmong the various coagulation parameters, there was no significant difference between saline and muscle (p > 0.05), except in the APTT using factor X–deficient plasma (mean APTT 133.89 seconds and 185.10 seconds for muscle and saline, respectively; p < 0.0001). Higher concentrations of the muscle extract (>0.5 mg/mL) increased platelet aggregation from 23.9% to 85.5% (p = 0.0001).ConclusionPlatelet aggregation plays a role in the hemostatic efficacy of muscle grafts. Even though action on the coagulation pathway via APTT is statistically significant, clinical significance may be low.
