Plurilinguismo e francofonia in Senegal: contatto, interferenza e mediazione linguistico-culturale nello spazio francofono

L\u2019analisi dell\u2019interferenza sul campione di testi selezionato (stampa e letteratura) che non vuole senz\u2019altro essere esaustivo ma si rivela gi\ue0 significativo, ha evidenziato un elevato numero di indizi di contaminazione e di creativit\ue0 lessicale nella lingua francese scritta del Senegal. In particolare, le neologie, siano esse denominative o stilistiche, i prestiti, siano essi integrali o adattati alla lingua d\u2019arrivo, riflettono non solo e non tanto l\u2019esigenza di nominare un oggetto o un concetto nuovi, o una volont\ue0 di esprimere il proprio pensiero in maniera inedita, come nel caso dei prestiti di lusso, quanto \u201cune motivation de manque qui r\ue9side dans la non\u2013conformit\ue9 des termes existant dans le lexique avec le contenu \ue0 exprimer.\u201d Anche laddove lo scrittore sceglie di operare una mediazione, rivolta soprattutto al lettore non wolofono, preferisce ricorrere alle note esplicative a pi\ue9 pagina, poich\ue9, come afferma Guilbert, che d\ue0 una giustificazione in proposito, \u201cle locuteur ne se r\ue9sout pas \ue0 recourir \ue0 la p\ue9riphrase synonimique qui permettrait de suppl\ue9er au terme absent.\u201d Per la lingua giornalistica e letteraria del S\ue9negal, quindi, \ue8 pi\uf9 che mai adeguato parlare di predominanza di un\u2019interferenza di tipo compensatorio, in quanto la lingua francese non sarebbe in grado di esprimere un\u2019idea, un concetto, una realt\ue0 appartenente all\u2019hypoculture di riferimento dello scrivente, cio\ue8 non sarebbe adeguata a tradurre, nel senso etimologico del termine, l\u2019identit\ue0 della cultura di partenza. Tale constatazione induce a credere che sarebbe riduttivo qualificare l\u2019operazione che compiono gli scrittori e, anche se in misura minore, i giornalisti, di semplice traduzione o trasposizione da una lingua all\u2019altra, perch\ue9 si tratta, invece, di un\u2019operazione pi\uf9 complessa, cio\ue8 di una trasposizione da una lingua/cultura a un\u2019altra. O meglio, come affermano Ladmiral e Lipiansky, \u201cda una sociolingua a un\u2019altra. L\u2019analisi condotta ha fatto quindi emergere con forza che l\u2019interferenza linguistica \ue8 in realt\ue0 rappresentativa di un fenomeno pi\uf9 ampio e importante, che va sotto il nome di \u201cprestito culturale\u201d. Come \ue8 noto, in quanto forma di comportamento, la lingua riflette il contesto culturale. Abbiamo visto in particolare, attraverso l\u2019analisi del campione di testi sul piano lessicale, come il complesso sistema plurilinguistico senegalese sia il riflesso di una ricca e dinamica identit\ue0 multidimensionale. Era nostra intenzione dimostrare, in ultima analisi, che la presenza quantitativa e qualitativa dell\u2019interferenza linguistica \ue8 di tale portata da corroborare le tesi che vedono in una definizione rinnovata di francofonia, cio\ue8 in un\u2019ottica polinomica e pluricentrica, l\u2019unica via di uscita dall\u2019impasse che attualmente sta attraversando tale concetto. Da questa nuova prospettiva, allora possiamo rispondere affermativamente ma in modo pi\uf9 preciso al nostro interrogativo iniziale: il Senegal, che \ue8 prima di tutto un paese plurilingue, \ue8 anche un paese francofono

Ultrasound shear wave elastography for liver disease. A critical appraisal of the many actors on the stage

In the last 12\u200a-\u200a18 months nearly all ultrasound manufacturers have arrived to implement ultrasound shear wave elastography modality in their equipment for the assessment of chronic liver disease; the few remaining players are expected to follow in 2016.When all manufacturers rush to a new technology at the same time, it is evident that the clinical demand for this information is of utmost value. Around 1990, there was similar demand for color Doppler ultrasound; high demand for contrast-enhanced ultrasonography was evident at the beginning of this century, and around 2010 demand increased for strain elastography. However, some issues regarding the new shear wave ultrasound technologies must be noted to avoid misuse of the resulting information for clinical decisions. As new articles are expected to appear in 2016 reporting the findings of the new technologies from various companies, we felt that the beginning of this year was the right time to present an appraisal of these issues. We likewise expect that in the meantime EFSUMB will release a new update of the existing guidelines 1 2.The first ultrasound elastography method became available 13 years ago in the form of transient elastography with Fibroscan(\uae) 3. It was the first technique providing non-invasive quantitive information about the stiffness of the liver and hence regarding the amount of fibrosis in chronic liver disease 3. The innovation was enormous, since a non-invasive modality was finally available to provide findings otherwise achievable only by liver biopsy. In fact, prior to ultrasound elastography, a combination of conventional and Doppler ultrasound parameters were utilized to inform the physician about the presence of cirrhosis and portal hypertension 4. However, skilled operators were required, reproducibility and diagnostic accuracy were suboptimal, and it was not possible to differentiate the pre-cirrhotic stages of fibrosis. All these limitations were substantially improved by transient elastography, performed with Fibroscan(\uae), a technology dedicated exclusively to liver elastography. Since then, more than 1300 articles dealing with transient elastography have been listed in PubMed, some describing results with more than 10,000 patients 5. The technique has been tested in nearly all liver disease etiologies, with histology as the reference standard. Meta-analysis of data, available in many etiologies 6, showed good performance and reproducibility as well as some situations limiting reliability 5. Thresholds for the different fibrosis stages (F0 to F4) have been provided by many large-scale studies utilizing histology as the reference standard 7. Transient elastography tracks the velocity of shear waves generated by the gentle hit of a piston on the skin, with the resulting compression wave traveling in the liver along its longitudinal axis. The measurement is made in a 4\u200acm long section of the liver, thus able to average slightly inhomogeneous fibrotic deposition.In 2008 a new modality became available, Acoustic Radiation Force Impulse (ARFI) quantification, and classified by EFSUMB 1 as point shear wave elastography (pSWE), since the speed of the shear wave (perpendicular to the longitudinal axis) is measured in a small region (a "point", few millimeters) at a freely-choosen depth within 8\u200acm from the skin. This technology was the first to be implemented in a conventional ultrasound scanner by Siemens(\uae) 8. Several articles have been published regarding this technology, most with the best reference standards 9, some including findings on more than 1000 hepatitis C patients 10 or reporting meta-analysis of data 11. Although the correlation between Siemens pSWE and transient elastography appeared high 12 13, the calculated thresholds for the different fibrosis stages and the stiffness ranges between the two techniques are not superimposable.Interestingly, pSWE appears to provide greater applicability than transient elastography for measuring both liver 13 and spleen stiffness, which is a new application of elastography 14, of interest for the prediction of the degree of portal hypertension 15 16.Nowadays other companies have started producing equipment with pSWE technology, but only very few articles have been published so far, for instance describing the use of Philips(\uae) equipment, which was the second to provide pSWE. These articles show preliminary good results also in comparison with TE 17 18. Not enough evidence is currently available in the literature about the elastographic performance of the products most recently introduced to the market. Furthermore, with some products the shear wave velocities generated by a single ultrasound acoustic push pulse can be measured in a bidimensional area (a box in the range of 2\u200a-\u200a3\u200acm per side) rather than in a single small point, producing a so-called bidimensional 2D-SWE 1. The stiffness is depicted in color within the area and refreshing of the measurement occurs every 1\u200a-\u200a2 seconds. Once the best image is acquired, the operator chooses a Region Of Interest (ROI) within the color box, where the mean stiffness is then calculated. 2D-SWE can be performed as a "one shot" technique or as a semi-"real-time" technique for a few seconds (at about 1 frame per second) in order to obtain a stable elastogram. With either technique, there should be no motion/breathing during image acquisition. A bidimensional averaged area should overcome the limitation of pSWE to inadvertently investigate small regions of greater or lesser stiffness than average. A shear wave quality indicator could be useful to provide real-time feedback and optimize placement of the sampling ROIs, a technology recently presented by Toshiba(\uae), but which is still awaiting validation in the literature.Supersonic Imagine by Aixplorer(\uae) which works with a different modality of insonation and video analysis compared to the the previously-mentioned three techniques (i.\u200ae., transient elastography, pSWE and 2D-SWE), leading to a bidimensional assessment of liver stiffness in real time up to 5\u200aHz and in larger regions; thus this technique is also termed real-time 2\u200aD SWE. It has been available on the market for a few years 19 20, and many articles have been published showing stiffness values quite similar to those of Fibroscan(\uae) 21; likewise, defined thresholds based on histological findings have appeared in several articles 19 20 21.After this brief summary of the technological state of the art we would like to mention the following critical issues that we believe every user should note prior to providing liver stiffness reports. \ub7 The thresholds obtained from the "oldest" techniques for the various fibrosis stages based on hundreds of patients with histology as reference standard cannot be straightforwardly applied to the new ultrasound elastography techniques, even if based on the same principle (e.\u200ag. pSWE). In fact, the different manufacturers apply proprietary patented calculation modes, which might result in slightly to moderately different values. It should be kept in mind that the range for intermediate fibrosis stages (F1 to F3) is quite narrow, in the order of 2\u200a-\u200a3 kilopascal (over a total range spanning 2 to 75 kPa with Fibroscan), so that slightly different differences in outputs could shift the assessment of patients from one stage to another. Comparative studies using phantoms and healthy volunteers, as well as patients, are eagerly awaited. In fact, the equipment might not produce linear correlations of measurements at different degrees of severity of fibrosis. As a theoretical example, some equipment might well correlate in their values with an older technique, such as transient elastography, at low levels of liver fibrosis, but not as well in cases of more advanced fibrosis or vice versa. Consequentely, when elastography data are included in a report, the equipment utilized for the measurement should be clearly specified, and conclusions about the fibrosis stage should be withheld if an insufficient number of comparative studies with solid reference standards are available for that specific equipment.. \ub7 Future studies using histology as a reference might be biased in comparison to previous studies, since nowadays fewer patients with chronic hepatitis C or hepatitis B undergo biopsy. In fact, due to wide availability of effective drugs as well as the use of established elastography methods for patients with viral hepatitis, most cases submitted to biopsy today have uncertain etiology or inconsistent and inconclusive clinical data. Therefore, extrapolated thresholds from such inhomogeneous populations applied to more ordinary patients with viral hepatitis might become problematic in the future, although no better solution is currently anticipated. This situation might lead to the adoption of a standard validated elastographic method as reference, but this has to be agreed-upon at an international level.. \ub7 Ultrasound elastography embedded in conventional scanners usually allows the choice of where to place the ROI within the color stiffness box and whether to confirm or exclude each single measurement when determining the final value. Thus, the operator has a greater potential to influence the final findings than with Fibroscan\uae, where these choices are not available. This has to be kept in mind to avoid the possibility that an operator could, even inadvertently, tend to confirm an assumption about that specific patient or to confirm the patient's expectations.. \ub7 Quality criteria for the new technologies following transient elastography are absent (depending on the manufacturer) or have not been satisfactorily defined, so that the information potentially inserted in a report cannot currently be judged for its reliability by the clinician..

Hybridité et diversité des langues en Afrique francophone. Perspectives (socio)linguistiques et littéraires

Actuellement, la diversité des langues est reconnue comme un atout pour l’humanité. Dans la vie des personnes ou institutions concernées par cette notion, cette dernière se catégorise par des concepts comme hybridité ou hétérogénéité notamment. Tout en privilégiant des perspectives (inter)disciplinaires, ce numéro de la revue Interfrancophonies permet de comprendre quelques modalités de traductions de ce phénomène qui suppose des croisements de langues et de rencontres en langues. Cela se fera sous deux parties. La première partie privilégie une conception d’inspiration linguistique ou sociolinguistique des langues. Elle met prioritairement en œuvre une approche descriptive de rencontres entre langues européennes et africaines. Une deuxième partie des contributions s’appuie majoritairement sur des corpus littéraires pour expliciter les dimensions sociales des langues et des cultures dans des situations africaines. Il ne faut toutefois pas croire en ce découpage disciplinaire fait uniquement pour un besoin technique, l'organisation des articles de ce numéro. En fait, certaines contributions se veulent plutôt in(ter)disciplinaires, du fait même des thématiques soulignées (exemples : la minoration, l’hétéroglossie ou la construction identitaire

Strategies for Retaining Employees for Call Centers

Voluntary employee turnover has several adverse consequences for call center managers, including lowered productivity and decreased profitability. The purpose of this descriptive multiple case study was to explore strategies used to reduced voluntary employee turnover among 2 call center managers in the southern United States. These managers had been recommended by the human resource directors of the organizations because of their implementation of strategies to reduce voluntary employee turnover. The conceptual framework for this study was Herzberg\u27s motivation-hygiene theory. Data were collected from semistructured face-to-face interviews and employee handbooks. The data analysis consisted of compiling the data, disassembling the data into common codes, reassembling the data into themes, interpreting the meaning, and reporting the themes. The use of member checking and methodological triangulation increased the trustworthiness of the study. Themes that emerged were job satisfaction, employee compensation, opportunity and advancement, reward and recognition, and employee engagement. Recommendations for action include selecting strategies for reducing voluntary employee turnover and using the strategies to improve the commitment of the workers. The findings from this study may contribute to social change by providing strategies that call center managers can use to reduce voluntary employee turnover, thereby positively improving the standard of living for families, and strengthening community wealth and well-being

Monocrystalline silicon carbide nanoelectromechanical systems

SiC is an extremely promising material for nanoelectromechanical systems given its large Young's modulus and robust surface properties. We have patterned nanometer scale electromechanical resonators from single-crystal 3C-SiC layers grown epitaxially upon Si substrates. A surface nanomachining process is described that involves electron beam lithography followed by dry anisotropic and selective electron cyclotron resonance plasma etching steps. Measurements on a representative family of the resulting devices demonstrate that, for a given geometry, nanometer-scale SiC resonators are capable of yielding substantially higher frequencies than GaAs and Si resonators

Effects of an intravaginal GnRH analogue administration on rabbit reproductive parameters and welfare

Abstract On commercial farms, rabbit does are subjected to a reproductive rhythm that does not account for their welfare or physiology, leading to reduced longevity and consequently high annual replacement. The European Food Safety Authority (EFSA) recommends limited and infrequent use of hormone treatments, and suggests replacement with alternative methods that do not threaten animal welfare when possible. In the present study, we aimed to determine whether the GnRH analogue lecirelin acetate could be administered by inclusion in the seminal dose during insemination. Twenty 9-month-old does (Grigio del Monferrato, autochthonous Italian breed),each having two previous deliveries, were individually housed and divided into two groups at artificial insemination. The control group received 0.2 mL of intramuscular lecirelin (Dalmarelin, Fatro®, Italy) prior to insemination. The intravaginal group was inseminated with a seminal dose that included 0.3 mL Dalmarelin. The experiment was performed for six consecutive reproductive cycles at 42-day intervals, and included a total of 120 inseminations. Prior to each insemination, the heterospermic pooled semen samples were assessed for sperm motility and morphology. Each ejaculate was divided into two samples, with and without lecirelin addition. Compared to the control group, the does with intravaginal Dalmarelin administration showed equal or greater sexual receptivity, which resulted in a higher fertility rate over increasing cycles. The seminal dose volume was very low, possibly explaining the better results in the intravaginal group, which received a similar amount of hormone (0.3 mL/doe) as the control group (0.2 mL/doe). The negative performance of the control group may have also been due to anti-GnRH formation, and the more stressful method of ovulation induction. The number of live-born kits did not significantly differ between groups. Progressive motility was significantly positively correlated with motility characteristics, including VAP, VSL, ALH, BCF, STR, and LIN. Overall, our present findings supported that the incorporation of GnRH in a seminal dose could be used for ovulation induction in rabbit does. Further studies should identify the optimal dose of GnRH for intravaginal administration, taking into account that the intravaginal absorption capacity is about 10 times smaller than the intramuscular absorption capacity

Evaluation of carcass and meat traits of Muscovy duck fed with black soldier fly partially defatted meal

The aim of this study was to evaluate the carcass characteristics and breast meat quality in Muscovy duck (Cairina moschata domestica) fed different inclusion levels of a partially defatted black soldier fly larva (BSF) meal. A total of 256 Muscovy ducklings (average live weight, LW: 71.32\ub12.70 g) were reared from day 3 to day 48 and randomly allotted in 32 pens (8 replicates/treatment). Four different diets were formulated with increasing substitution level of corn gluten meal with BSF larva meal (0, 3, 6 and 9%; BSF0, BSF3, BSF6 and BSF9, respectively) and divided in 3 feeding phases: starter (1-14 days), grower (14-35 days) and finisher (35-48 days). At day 48, 2 animals/replicate were slaughtered and dissected to determine their carcass yields. The weights of spleen, bursa of Fabricius, liver, heart and abdominal fat were recorded. Breast and thigh muscles were then excised from 16 ducks/treatment and weighted. Ultimate pH (pHu) and L*, a*, b* colour values were then measured on breast muscle. The collected data were tested by means of oneway ANOVA evaluating the effect of dietary BSF inclusion level by polynomial contrasts. Significance was declared at P<0.05. The inclusion of BSF did not affect final LW (2,515.68\ub192.42 g on average). Hot and cold carcass weights showed a quadratic response (P<0.05) to increasing BSF larva meal, with a minimum corresponding to BSF6; however, refrigeration losses were not affected by treatments. Weight of spleen, bursa of Fabricius, liver and heart did not differ among treatments. The weight of abdominal fat showed a quadratic response to increasing BSF meal with a minimum corresponding to BSF6 group (P<0.05). Breast and thigh yields, pHu and L*, a*, b* colour values did not differ among groups. With the exception of BSF6, the inclusion of BSF meal did not affect meat traits and carcass characteristics, confirming the potential use of BSF meal in Muscovy duck diets

Apparent digestibility of insect protein meals for rainbow trout

Insect meals are considered to be promising future ingredients for aquaculture feeds. In past feeding trials in rainbow trout, insect meals were included in diets only on the basis of their nutrients content and energy density without taking into account their biological availability due to the lack of their digestible values. Apparent digestibility (ADC) provides good indication of the bioavailability of nutrients and energy thus providing rational basis for the correct inclusion of feedstuffs. The aim of this research was to assess, in an in vivo trial on rainbow trout, the ADC of five full fat insect meals: one Tenebrio molitor (TM), two Hermetia illucens obtained through two different process (HI1 and HI2), one Musca domestica (MD), and one Alphitobius diaperinus (AD). Fish were fed a high-quality reference diet (R) and test diets obtained mixing the R diet with each of the test ingredients at a ratio of 70:30. Diets contained 1% celite as inert marker. Fish were fed to visual satiety twice a day and faecal samples collected using a continuous automatic device. Faeces were freeze dried and frozen (-20 \ub0C) until analyses. The ADC of dry matter, crude protein and ether extract of each insect meal diet were calculated. ADC for dry matter varied between 70.07 (HI1) and 80.85 (TM). ADC for protein was above 84% in all treatments and resulted the highest in MD, TM and AD treatments. Ether extract apparent digestibility significantly differed among diets with the highest value reported for TM treatment. All treatments reported values higher than 96%. Observed differences could be due to the insect species and meal treatment but in general, tested insect meals were highly digestible for rainbow trout. The results from this research could be useful to optimize the diet formulation
