    This case study describes the application of the VCW – Value Creation Wheel to a social impact project carried out by Girl Move, a social organization operating in the region of Nampula, Mozambique. The objective of the project is to stimulate the empowerment of young women in a developing country, by fostering leadership competencies, teaching and mentoring skills, and consequently present of a career path that will have an impact on society. The VCW is a meta-framework that can help to achieve different types of objectives (both individual or organizational), as it is adaptable to a wide range of situations. This case highlights how the benefits brought by the VCW were of great help to solve different challenges associated with individual insecurities and hesitations, helping young people trying to define their professional future, and their desire to fulfill their vocation while having an impact on the world

    VERTICALIZATION, WARTIME AMERICANIZATION EFFORTS, AND THE GERMAN-TO-ENGLISH SHIFT AMONG THE MENNONITE BRETHREN OF HILLSBORO, KANSAS

    Get PDF
    In the early to mid-twentieth century, the Mennonite Brethren (MB) community of Hillsboro, Kansas, underwent a systematic language shift from German to English. Many attribute this shift to the anti-German sentiment and resulting discriminatory governmental measures caused by the World Wars. However, like many American communities in the early twentieth century, the MB in Hillsboro also underwent a process of community change called verticalization. Verticalization refers to the process by which a community's connections become less internally and locally bound (horizontal) and more externally and hierarchically bound (vertical). In recent scholarship (Salmons 2002; Lucht, Frey, & Salmons 2011), verticalization--and not the World Wars or other factors like urban-rural asymmetry--has been seen to have the strongest correlation with language shift. Using US census data, information about the community's German-language press, and meeting minutes from two area churches, this project traces the shift from German to English in this community as well as its verticalization. Additionally, it explores the effects of the World Wars on this community's language shift. The findings do not show a correlation between language shift and the World Wars, but they do show a strong consistency between verticalization and language shift. Crucially, this provides support for the theory of verticalization as a facilitator of language change.Master of Art

    L’enseignement du grec et du latin : le paradoxe du mouvement

    Get PDF
    L’article cherche à proposer une réflexion sur la désaffection des jeunes pour les langues anciennes, à partir de remarques concernant l’enseignement de la rhétorique dans le monde grec des premiers siècles de notre ère. En effet, bien que la rhétorique connaisse alors une période particulièrement faste, les professeurs ont, comme en témoignent un certain nombre de textes, du mal à persuader leurs étudiants de suivre les cours. Ces derniers sont davantage attirés, malgré le prestige de ces études, par de nombreuses activités de loisirs qui s’offrent à eux. Des orateurs célèbres comme Aelius Aristide ou Libanios vont chercher à démontrer à leurs élèves que l’effort demandé par les exercices de rhétorique est bien plus profitable. Pourtant, face à l’apparition de nouvelles modes, comme la pantomime, les deux rhéteurs vont s’affronter, l’un, Aristide, restant intransigeant, l’autre, Libanios, faisant preuve de plus d’ouverture, mais gardant en toile de fond ses exigences. C’est sans doute en restant sur des positions fermes d’exigence, tout en adaptant l’enseignement à l’époque, que nous pourrons, à notre tour, préserver, et développer, l’enseignement des langues anciennes.The loss of interest in classical languages amongst young people is the subject of this article, which is based on remarks regarding the same phenomenon observed in the teaching of rhetoric in the Greek world of the first centuries AD. Indeed, although this period was particularly prosperous as regards rhetoric, we find that, according to some texts, teachers found it difficult to persuade their students to attend classes. Despite the prestige of this curriculum, the students were much more attracted by many leisure activities with which they were presented. Famous orators like Aelius Aristides or Libanius tried to demonstrate to their students that the effort requested by rhetorical exercises was much more beneficial. However, as new trends appeared, such as pantomime, the two rhetoricians confronted each other. The former, Aristides, stayed impervious to this kind of show. The latter, Libanius, was more open to it while keeping his standards as a backdrop. Adjusting to the times, but without demagogy, is with no doubt the attitude we must adopt today to preserve and develop the teaching of classical languages

    Catalyst-free soft-template synthesis of ordered mesoporous carbon tailored using phloroglucinol/ glyoxylic acid environmentally friendly precursors

    Get PDF
    International audienceCarbon porous materials with a periodically ordered pore structure, controlled pore size and geometry and high thermal stability are synthesized using self-assembly of environmentally friendly phloroglucinol/ glyoxylic acid precursors with an amphiphilic triblock copolymer template. Glyoxylic acid, a plant-derived compound, is used for the first time as a substituent of carcinogen formaldehyde usually employed in such a synthesis. Thanks to the double functionality, i.e., aldehyde and carboxylic acid, glyoxylic acid plays not only the role of a cross-linker for the formation of the resin but also the role of a catalyst by creation of H-bonding or specific reactions between the precursors. Hence, no extra catalyst such as strong acids (HCl) or bases (NaOH) is any longer required. Carbon films and powders were successfully prepared with high surface areas (up to 800 m2 g−1), high porous volume (up to 1 cm3 g−1), tunable pore size (0.6 nm to 7 nm) and various pore architectures (hexagonal, cubic, and ink-bottle) by tuning the precursor ratio and by applying different manufacturing engineering strategies. Insights on the synthesis mechanism of the phenolic resin and carbon mesostructures were obtained using several analysis techniques, i.e., nuclear magnetic resonance (13C NMR) and FTIR spectroscopy, temperature programmed desorption coupled with mass spectrometry (TPD-MS) and thermo-gravimetric analysis (TGA)

    Insights on the Na+ ion storage mechanism in hard carbon: Discrimination between the porosity, surface functional groups and defects

    Sodium ion batteries (SIBs) using hard carbon as negative electrode hold the promise of being low cost alternative to lithium ion batteries (LiBs). However, the Na+ storage mechanism in hard carbons is not fully understood yet and the attribution of Na storage in the sloping and plateau regions of the sodiation/desodiation curves remains still controversial. The current work employs N-2, Kr and CO2 gases to correctly assess the changes in hard carbon porosity induced by different pyrolysis temperature of cellulose. The sloping capacity was found to decrease with the decrease of the specific area of ultramicropores measurable only by CO2 adsorption, while the plateau capacity demonstrated an opposite behavior. The high temperature derived carbons (> 1400 degrees C) present no porosity which disqualifies the attribution of plateau region to the adsorption of Na+ in the nanopores but rather the insertion between the pseudo-graphitic domains. Temperature programmed desorption coupled with mass spectrometry (TPD-MS) was performed to determine the nature and the quantity of oxygen surface functional groups followed by oxygen chemisorptions to assess the amount of carbon edge defects expressed by active surface area (ASA) values. A decrease in the amount of oxygen groups and active surface area with the increase of the pyrolysis temperature was observed which is accompanied by a decrease of the sloping capacity. These results shed light in the storage mechanisms, the sloping region being ascribed mainly to the interaction of Na+ with carbon edge defects and adsorption in the microporosity while the plateau region assigned to the intercalation of Na+ in the pseudo-graphitic nanodomains

    BACKGROUND: The aim of our study was to assess the feasibility of minimally invasive digestive anastomosis using a modular flexible magnetic anastomotic device made up of a set of two flexible chains of magnetic elements. The assembly possesses a non-deployed linear configuration which allows it to be introduced through a dedicated small-sized applicator into the bowel where it takes the deployed form. A centering suture allows the mating between the two parts to be controlled in order to include the viscerotomy between the two magnetic rings and the connected viscera. METHODS AND PROCEDURES: Eight pigs were involved in a 2-week survival experimental study. In five colorectal anastomoses, the proximal device was inserted by a percutaneous endoscopic technique, and the colon was divided below the magnet. The distal magnet was delivered transanally to connect with the proximal magnet. In three jejunojejunostomies, the first magnetic chain was injected in its linear configuration through a small enterotomy. Once delivered, the device self-assembled into a ring shape. A second magnet was injected more distally through the same port. The centering sutures were tied together extracorporeally and, using a knot pusher, magnets were connected. Ex vivo strain testing to determine the compression force delivered by the magnetic device, burst pressure of the anastomosis, and histology were performed. RESULTS: Mean operative time including endoscopy was 69.2 ± 21.9 min, and average time to full patency was 5 days for colorectal anastomosis. Operative times for jejunojejunostomies were 125, 80, and 35 min, respectively. The postoperative period was uneventful. Burst pressure of all anastomoses was ≥ 110 mmHg. Mean strain force to detach the devices was 6.1 ± 0.98 and 12.88 ± 1.34 N in colorectal and jejunojejunal connections, respectively. Pathology showed a mild-to-moderate inflammation score. CONCLUSIONS: The modular magnetic system showed enormous potential to create minimally invasive digestive anastomoses, and may represent an alternative to stapled anastomoses, being easy to deliver, effective, and low cost

    Relationship between the carbon nano-onions (CNOs) surface chemistry/defects and their capacitance in aqueous and organic electrolytes

    The effect of surface functionalities on the supercapacitors performances has been highlighted often in many works. However, studies devoted to the influence of carbon defects did not gain particular attention due to the difficulty to quantify such parameter. In this context, carbon nano-onions were used as model material in order to understand the influence of the surface chemistry (nature and amount of oxygen groups) and structural defects (active surface area, ASA) on the capacitance. Different types of thermal treatments in oxidizing or reducing atmospheres allowed to finely tune the surface chemistry and the ASA as demonstrated by temperature programmed desorption coupled with mass spectrometry (TPD-MS). For the first time, the presice control of these characteristics independently one of each other allowed to highlight an important influence of the carbon defects on the capacitance in organic and aqueous electrolytes which outbalance the oxygen functional group effect
