Subordinação Adverbial : um estudo cognitivo sobre o infinitivo, o clítico SE e as formas verbais finitas em proposições adverbiais do Português Europeu / Adverbial subordination : a cognitive study on the infinitive, the clitic SE and finite verb forms in European Portuguese adverbial clauses

Vesterinen, Rainer January 2006 (has links)
<p>The aim of this study is to analyse the variation between infinitive and finite verb adverbial clauses in European Portuguese. In order to understand this variation, three central questions are raised: (1) What determines the use of the uninflected vs. the inflected infinitive in same-subject adverbial clauses? (2) What does the pronoun SE signal in these adverbial clauses? (3) What difference is there between the use of the inflected infinitives vs. finite verbs in different subject adverbial clauses?</p><p>Earlier investigations about these three questions are discussed. One conclusion of this review is that former research almost exclusively has been conducted from a traditional or formalistic point of view that has given priority to structural descriptions instead of semantic or conceptual explanations. In contrast to this, the present study endeavours to examine these issues from a cognitive linguistic perspective.</p><p>It is claimed that the use of the inflected infinitive in adverbial same-subject clauses may be explained by contextual factors which create a cognitive need to highlight the subject of the adverbial clause. Further, an analysis about how the grammatical micro-context can determine the interpretation of the clitic pronoun SE as a marker for a generic trajector is conducted. It is also argued that the difference between infinitive and finite adverbial clauses can bee explained by means of theories of subjectification and mental spaces.</p><p>The conclusion is drawn that a cognitive approach to grammar can, indeed, shed light on the issues considered.

La compétence à se situer : comment favoriser l'acquisition de compétences professionnelles chez les adultes en difficulté de réinsertion

Gérard, Jean-Montcler 24 June 1994 (has links) (PDF)
Cette recherche empirique en didactique, sur un terrain de formation d'adultes "de bas niveau de qualification" en difficulté de réinsertion, vise à mettre en évidence, et proposer aux formateurs, les éléments permettant de réunir les conditions les plus favorables aux apprentissages de compétences professionnelles. L'investigation révèle que, pour ces adultes, l'intrication très forte entre les facteurs sociaux économiques (perte d'emploi, de revenus et de statut) et les facteurs individuels (isolement, fragilisation psychologique) se traduit par une importante perte de repères dans le temps, l'espace, les connaissances et la communication avec autrui. Une partie de cette thèse est consacrée à l'étude des théories d'organisation des situations didactiques et des apports du courant de l'éducabilité cognitive à partir desquels sont préconisés le cadre pédagogique et le type d'intervention des formateurs. Ceux-ci auront le souci d'élaborer des situations complexes, de remédier aux déficits d'alimentation de la "représentation fonctionnelle de la conduite", au moyen d'activités qui doivent favoriser le travail collectif, les confrontations, la revalorisation de l'image de soi et l'anticipation. L'analyse des formations, ainsi conduites, montre des effets à long terme parce que le travail porte sur la (re)construction de repères aussi bien personnels, affectifs que cognitifs. Pour ce faire, les sujets devraient être confrontés à des situations qui fournissent l'occasion d'élaborer des significations, d'identifier des points de vue différents, de retrouver des repères et de construire des connaissances nouvelles. Ainsi, contrairement aux pratiques les plus courantes, il faudrait que les situations présentent un niveau de complexité suffisant pour déclencher la recherche du sens et l'étude des relations et qu'elles se déroulent dans un contexte d'exercice professionnel réel. Enfin, il apparaît que la capacité à "se situer", développée dans les premières semaines de formation, favorise l'acquisition des compétences professionnelles en même temps qu'elle permet l'émergence d'un "projet de soi".

Finansiella nyckeltal - analysinstrument eller reklam?

Westdahl, Ann-Britt January 2009 (has links)
Är de svenska storbankernas presentation av finansiella nyckeltal jämförbara? Det är frågan jag ställt mig i syfte att skapa förståelse för omfattningen av skillnaden mellan bankernas jämförande information via finansiella nyckeltal. Analysen har utförts genom en fallstudie, där ett systemsynsätt tillämpats, och har visat att vare sig bankernas presentation av finansiella nyckeltal, eller teorier kring nyckeltal, kan anses vara jämförbara. Stora skillnader existerar, både kring vilka nyckeltal som presenteras, vad de kallas och hur de beräknas. Finansiella nyckeltal kan således inte anses vara användbara som analysverktyg, eller bidra till den inre marknadens funktion. Resultatet av studien baserar sig på analyser av bankernas presenterade finansiella nyckeltal, resultat- och balansräkningar, ägarstrukturer och börskurser. Grunddata har hämtats från bankernas årsredovisningar under perioden 2004 – 2008, från Finansinspektionen och Stockholmsbörsen. Jag har även intervjuat representanter från bankerna och Finansinspektionen, en analytiker och en ekonomijournalist. Den övergripande bilden och djupa förståelsen har jag fått av Jacob Palmstierna, som haft godheten att dela med sig av sin fyrtioåriga erfarenhet och ovärderliga kunskap om den svenska bankbranschen. Uppsatsen innefattar även metodutveckling i form av en konceptuell omvärldsmodell.

Effektiviseringsarbete av ett produktionsflöde : -Med kundanpassade produkter / Efficiency work of a production flow : -With customized products

Iversen, Gabriela, Lundquist, Jonatan January 2015 (has links)
En hållbar tillväxt, hög konkurrenskraft och goda möjligheter att anställa nytt folk kan nås om företag blir bättre på att utveckla sig själva och bygga samordnade produktionssystem, vilket har blivit av allt större vikt. Fallstudien är utförd på företaget LKM AB, som producerar olika kablar och kablagemonteringar. Huvudsyftet med fallstudien är att utreda hur kundanpassningen påverkar den interna effektiviseringen av ett produktionsflöde i en tillverkande verksamhet. En nulägesanalys utfördes för att etablera nuläget och analysera den, fokus låg därefter på packningsoperationen, vilket är operationen närmast kundönskemålen. Författarna påbörjade därefter att arbeta med Kata genom att sätta upp ett måltillstånd, detta visar vart företaget är idag och vart de vill vara inom cirka en månads tid. Genom att arbeta med ett effektivt experimenteringsverktyg kallat PDCA-uppföljningsblankett, måltillståndet var uppnått inom tidsperioden och resultatet blev följande: - Leveransen gick på en pall istället för fyra stycken. - Packningstiden reducerades med 60 %. - Kontrolltiden hos kunden reducerades med 30-40 %. Detta visar att metoden och arbetssättet är mycket effektivt.

Le professeur de lettres fictif : un sujet culturel québécois

Gérin, Dominique January 2013 (has links)
Cette étude sociocritique du professeur de lettres fictif dans le roman québécois de 1995 à 2010 est guidée par les travaux d’André Belleau (Le Romancier fictif), de Roseline Tremblay (L'Écrivain imaginaire) et du Groupe de recherche sur les médiations littéraires et les institutions (Fictions du champ littéraire) portant sur la figuration de l’écrivain. En ce sens, elle examine les manifestations polyphoniques et plurilinguistiques dans des textes romanesques (Mikhaïl Bakhtine) en faisant des figures de l’écrit, telles que définies par Femand Roy, le pivot d’ancrage, textuel et cotextuel, qui constitue les sociotextes, ici les romans du professeur de lettres. L’inéluctable quête de la légitimité de la parole et du savoir de ce "sujet culturel" (Edmond Cros) offr, avec Hadassa (2006) de Myriam Beaudoin, La Blonde de Patrick Nicol (2005) de Patrick Nicol, Qu’est-ce qui passe ici si tard?

Ständiga förbättringar för konkurrenskraftig och hållbar utveckling : En fallstudie utförd på Hammarplast Consumer AB, Tingsryd / Continuous improvements for competitive and sustainable development : A case study performed at Hammarplast Consumer AB, Tingsryd

Thuresson, Sarah, Johansson, Malin January 2014 (has links)
Studien är utförd på Hammarplast Consumer AB med syftet att skapa djupare förståelse i hur producerande verksamheter arbetar med sina ständiga förbättringar och hur de kan på ett strukturerat sätt utföra förbättringar i den dagliga styrningen för att nå konkurrenskraftig och hållbar utveckling. För att detta skulle uppnås dokumenterades företagets vision och utmaning, som sedan bröts ned till ett detaljrikt måltillstånd med hjälp av att nuläget analyserades i den valda processen. Därefter gjordes små, snabba steg och korrigeringar mot måltillståndet, vilket genomfördes med planering, genomföring, reflektering och uppföljning. Det gav förbättringar som var värdehöjande för företaget och som resulterade i ett steg närmare visionen. Det strukturerade tillvägagångssättet, kata, bidrog till att medarbetarna blev engagerade och involverade. I de avslutande kapitlen fördes en diskussion om hur företaget kan på ett strukturerat sätt utföra deras ständiga förbättringar i den dagliga styrningen som kommer att föra dem emot en konkurrenskraftig och hållbar utveckling.

Production and immunogenicity of selected proteins of Salmonella Enteritidis

Cui, Yun 11 1900 (has links)
Au cours des dernières années, Salmonella Enteritidis est devenus les sérotypes les plus souvent isolés chez les patients canadiens, les cas étant liés à la consommation de viande de poulet et d’œufs crus. Les vaccins tués commercialement disponibles pour la volaille, stimulent mal l'immunité mucosale, tandis que l'utilisation de vaccins vivants reste controversée. Par conséquent, un vaccin sous-unitaire par voie orale peut être une solution. Cinq protéines bactériennes ont été choisies comme candidates potentielles et identifiées, soit Glyceraldehyde-3-phosphate dehydrogenase, Enolase, Lipoamide dehydrogenase, DNA protection during starvation protein et Elongation factor-Tu. Notre objectif a été de produire et de purifier ces protéines et de démontrer leur immunogénicité. Les gènes des protéines ont été amplifiés et clonés dans le vecteur pQE-30 pour expression dans Escherichia coli M15. La purification a été effectuée par FPLC. Des poules pondeuses SPF ont été séparées en 6 groupes et injectées par voie intramusculaire à different âges avec une des 5 protéines, ou le PBS chez le groupe témoin. Les œufs ont été ramassés pendant l'expérience et du sang a été prélevé à 36 semaines d'âge. Les anticorps IgY ont été extraits à partir du jaune d'oeuf et du sérum, et les IgA à partir du blanc d'oeuf. Des immunodots, westernblots et ELISA ont évalué l'immunogénicité des protéines et les niveaux d'anticorps induits . Nous avons constaté que ces cinq protéines pourraient stimuler la production d'anticorps spécifiques in vivo. GAPDH, Enolase et DPS ont induit des titres d'anticorps plus élevés que LpdA et EF-Tu. / Over the past years, Salmonella Enteritidis (SE) has become the most prevalent serovars isolated in Canadian patients. Most cases in humans are associated with consumption of chicken meat, raw egg and related products. For controlling Salmonella transmission and infection in poultry, available commercially killed vaccines poorly stimulate mucosal immunity, while the use of live vaccines remains controversial. Therefore an oral subunit vaccine may be a solution. Five bacterial proteins were chosen as potential candidates and identified as Glyceraldehyde-3-phosphate dehydrogenase, Enolase, Lipoamide dehydrogenase, DNA protection during starvation protein and Elongation factor-Tu. Our objectives were to produce and purify these proteins and study their immunogenicity. The proteins genes were amplified and cloned into pQE-30 vector, then transformed into Escherichia coli M15 for expression. Purification was performed using FPLC. SPF laying hens were separated into 6 groups and injected intramuscularly 3 times at 16, 20 and 28 weeks of age. Five groups were injected with a single protein respectively while the sixth group was injected with PBS as control. Eggs were collected during the duration of the experiment and blood was collected when hens were sacrificed at 36 weeks of age. IgY was extracted from egg yolk and serum and IgA from egg white. Immunodot, westernblot and ELISA were used to evaluate the immunogenicity of proteins and antibody levels they induced. We found that these five proteins could stimulate production of specific antibody in vivo. GAPDH, Enolase and DPS induced higher antibody titer than LpdA and Ef-Tu.

Inferring biogeography from the evolutionary history of the giant freshwater prawn (macrobrachium rosenbergii)

de Bruyn, Mark January 2006 (has links)
The discipline of historical biogeography seeks to understand the contribution of earth history to the generation of biodiversity. Traditionally, the study of historical biogeography has been approached by examining the distribution of a biota at or above the species level. While this approach has provided important insights into the relationship between biological diversity and earth history, a significant amount of information recorded below the species level (intraspecific variation), regarding the biogeographical history of a region, may be lost. The application of phylogeography - which considers information recorded below the species level - goes some way to addressing this problem. Patterns of intraspecific molecular variation in wide-ranging taxa can be useful for inferring biogeography, and can also be used to test competing biogeographical hypotheses (often based on the dispersal-vicariance debate). Moreover, it is argued here that phylogeographical studies have recently begun to unite these two disparate views, in the recognition that both dispersal and vicariance have played fundamental roles in the generation of biodiversity. Freshwater dependent taxa are ideal model organisms for the current field of research, as they reflect well the underlying biogeographical history of a given region, due to limited dispersal abilities - their requirement for freshwater restricts them. To this end, this study documented the phylogeographical history of the giant freshwater prawn (Macrobrachium rosenbergii) utilising both mitochondrial (COI & 16S) and nuclear (microsatellite) markers. Samples (n = ~1000) were obtained from across most of the natural distribution of M. rosenbergii [Southern and South East (SE) Asia, New Guinea, northern Australia]. Initial phylogenetic analyses identified two highly divergent forms of this species restricted to either side of Huxley's extension of Wallace's Line; a pattern consistent with ancient vicariance across the Makassar Strait. Subsequent analyses of molecular variation within the two major clades specifically tested a number of biogeographical hypotheses, including that: 1.) a major biogeographical transition zone between the Sundaic and Indochinese biotas, located just north of the Isthmus of Kra in SE Asia, results from Neogene marine transgressions that breached the Isthmus in two locations for prolonged periods of time; 2.) Australia's Lake Carpentaria [circa 80 000 - 8 500 before present (BP)] facilitated genetic interchange among freshwater organisms during the Late Pleistocene; 3.) sea-level fluctuations during the Pleistocene constrained evolutionary diversification of M. rosenbergii within the Indo-Australian Archipelago (IAA); and 4.) New Guinea's Fly River changed course from its current easterly outflow to flow westwards into Lake Carpentaria during the Late Pleistocene. The results support hypotheses 1-3, but not 4. The potential for phylogeography to contribute significantly to the study of historical biogeography is also discussed.
