Oral English in different school settings

Hi ha molts tipus d’escoles diferents, i fins i tot, podem constatar que cada escola és diferent de les altres. Per aquesta raó, quan parlem sobre l’aprenentatge de l’anglès, no podem generalitzar una manera de fer-ho, perquè cada una d’elles tracta aquesta llengua de manera diferent. A més, pel que fa a l’aprenentatge d’una llengua, hi ha diferents habilitats involucrades, i entre totes aquestes, he centrat aquest projecte en l’habilitat oral. Aquesta recerca esta basada en l’observació de tres exemples de tipus d’escoles, i per ser més precisos, té l’objectiu d’aprofundir com tracten l’Anglès. D’aquesta manera, el principal objectiu d’aquest projecte és comparar l’habilitat oral dels alumnes d’aquestes escoles, tot considerant les seves diferències. Així doncs, amb el desenvolupament d’aquesta recerca, vaig voler descobrir si hi havien alguns alumnes amb millors habilitats orals que d’altres, i trobar-ne la possible raó.

La Dramatització: Anàlisi de la seva funció educativa

Aquest treball presenta la dramatització, remarcant la seva importància en l’educació. En la part principal es planteja conèixer què és la dramatització, perquè és important i com es relaciona amb l’educació, objectius que es resolen en la fonamentació teòrica. En la segona part es planteja l’objectiu de recerca, el qual vol donar resposta a Com es treballa la dramatització a l’escola?, fet que s’estudia a través de tres entrevistes a experts en l’aplicació de la dramatització a l’ensenyament. Finalment acabem veient que la dramatització s’aplica actualment a l’escola; que hi ha diversitat d’aplicacions però sempre tenen parts comunes que els mestres organitzen segons el seu objectiu i funcionament de l’aula; que la formació en art dramàtic és un pas important a realitzar, i que si parlem d’educació, l’escola i el seu equip directiu i educatiu, tenen un paper clau en la realització de la dramatització a l’escola.

La Bressola: Percepcions, actituds i motivacions del professorat en l'ús de les TIC

El present estudi de cas se centra en la identificació de les actituds, motivacions i percepcions vers les Tecnologies de la Informació i la Comunicació (TIC) que té el professorat de les escoles La Bressola. Existeix molta documentació del treball en la immersió lingüística de la llengua catalana que fan aquests centres, però no s’ha fet cap estudi que parli de l’ús de les TIC a La Bressola. El constant avenç tecnològic no només implica canvis en la societat, sinó també a nivell educatiu. Per aquest motiu, els docents han d’adaptar-se els nous canvis i saber com integrar els nous recursos digitals dins l’aula per continuar progressant en els processos d’ensenyament i aprenentatge. A través d’una enquesta dirigida al professorat de La Bressola, s’ha vist que els docents de La Bressola mostren una actitud optimista vers l’ús de les TIC, tot i que els principals factors que influeixen per a la bona integració de les eines és la falta de formació i de recursos digitals.

Glucagon-like peptide-I and the control of insulin secretion in the normal state and in NIDDM.

Potentiation of glucose-induced insulin secretion by intestinal factors has been described for many years. Today, two major peptides with potent insulinotropic action have been recognized: gastric inhibitory peptide and truncated forms of glucagon-like peptide I, GLP-I(7-37) or the related GLP-I(7-36)amide. These hormones have specific beta-cell receptors that are coupled to production of cAMP and activation of cAMP-dependent protein kinase. Elevation in intracellular cAMP levels is required to mediate the glucoincretin effect of these hormones: the potentiation of insulin secretion in the presence of stimulatory concentrations of glucose. In addition, circulating glucoincretins maintain basal levels of cAMP, which are necessary to keep beta-cells in a glucose-competent state. Interactions between glucoincretin signaling and glucose-induced insulin secretion may result from the phosphorylation of key elements of the glucose signaling pathway by cAMP-dependent protein kinase. These include the ATP-dependent K+ channel, the Ca++ channel, or elements of the secretory machinery itself. In NIDDM, the glucoincretin effect is reduced. However, basal or stimulated gastric inhibitory peptide and glucagon-like peptide I levels are normal or even elevated, suggesting that signals induced by these hormones on the beta-cells are probably altered. At pharmacological doses, infusion of glucagon-like peptide I but not gastric inhibitory peptide, can ameliorate postprandial insulin secretory response in NIDDM patients. Agonists of the glucagon-like peptide I receptor have been proposed as new therapeutic agents in NIDDM.

Política i empresa, companyes de viatge La qüestió catalana Reportatge digital sobre l’empresariat català i l’encaix Catalunya- Espanya. Valoracions entorn el debat sobiranista

El debat sobiranista català està a l‟ordre del dia i actualment no passa desapercebut en cap mitjà de comunicació ni tampoc en el món polític, econòmic i empresarial. El fet d‟estar tan viva una temàtica així de delicada està ocasionant controvèrsies dins l‟empresariat català o que té la seva empresa ubicada a Catalunya perquè tot plegat provoca moltes incerteses, que són el pitjor enemic dels empresaris i dels negocis. Tanmateix, però, les informacions publicades o emeses venen marcades per les opinions polítiques i periodístiques, que es troben censurades en certa mesura perquè segueixen una determinada línia política i/o editorial. Per això s‟ha elaborat un reportatge digital focalitzat en l‟empresariat català i l‟encaix Catalunya-Espanya que pretén aportar noves valoracions entorn a aquest debat donant veu a empresaris i professionals, entre altres. La part teòrica de la memòria defineix els conceptes bàsics que són de forçat coneixement per realitzar una part pràctica que ha de ser entesa per qualsevol persona i que s‟ha de tractar amb la major objectivitat possible. Per això, el web http://laquestiocatalana.cat aporta un llenguatge planer i les eines bàsiques per donar a conèixer una matèria molt criticada per alguns sectors. A través d‟entrevistes a personatges rellevants, el web introdueix nous punts de vista sobre una qüestió marcada, a simple vista, per la preocupació d‟un possible boicot per part d‟Espanya. Però aquesta no sembla ser la principal inquietud dels entesos, i és que hi ha altres aspectes encara més alarmants que poden influir en l‟empresariat i que no són tractats per cap mitjà de comunicació convencional.

Iowa Lottery Annual Report, 2014

A lot of things came together to make 2014 truly exceptional for the Iowa Lottery, and allowing us to fulfill winners’ dreams and raise record proceeds to make a difference in Iowans’ lives.

Transgenic reexpression of GLUT1 or GLUT2 in pancreatic beta cells rescues GLUT2-null mice from early death and restores normal glucose-stimulated insulin secretion.

GLUT2-null mice are hyperglycemic, hypoinsulinemic, hyperglucagonemic, and glycosuric and die within the first 3 weeks of life. Their endocrine pancreas shows a loss of first phase glucose-stimulated insulin secretion (GSIS) and inverse alpha to beta cell ratio. Here we show that reexpression by transgenesis of either GLUT1 or GLUT2 in the pancreatic beta cells of these mice allowed mouse survival and breeding. The rescued mice had normal-fed glycemia but fasted hypoglycemia, glycosuria, and an elevated glucagon to insulin ratio. Glucose tolerance was, however, normal. In vivo, insulin secretion assessed following hyperglycemic clamps was normal. In vitro, islet perifusion studies revealed that first phase of insulin secretion was restored as well by GLUT1 or GLUT2, and this was accompanied by normalization of the glucose utilization rate. The ratio of pancreatic insulin to glucagon and volume densities of alpha to beta cells were, however, not corrected. These data demonstrate that 1) reexpression of GLUT1 or GLUT2 in beta cells is sufficient to rescue GLUT2-null mice from lethality, 2) GLUT1 as well as GLUT2 can restore normal GSIS, 3) restoration of GSIS does not correct the abnormal composition of the endocrine pancreas. Thus, normal GSIS does not depend on transporter affinity but on the rate of uptake at stimulatory glucose concentrations.

Assistance au suicide en hôpital de soins aigus: sommes-nous prêts [Physician-assisted suicide in university hospital: are we ready?]

Assisting people to commit suicide has generated a passionate public debate. In exceptional situations, access to this support can be granted to the demanders in a hospital environment. So did the CHUV and the academic hospitals of Geneva draw up a procedure permitting, in principle, the access to an assistance to commit suicide. Two recent clinical situations experienced in the CHUV's Service of internal medicine have created a lot of discussions, doubts and revealed, sometimes, divergent positions. By the light of this clinical cases, we wished to share the perspective of the internist in charge of the ethician, of the chaplain, of the medical director, of the psychiatrist and of the palliative care responsible. Theses complex situations illustrate the deep ambivalence felt by the clinicians confronted to situations which require a multidisciplinary approach.

Diseño e implementación de una Web dinámica como herramienta para el control de obras en base al coste del proceso de construcción

En la actualidad estamos sufriendo una situación de crisis económica de dimensiones desproporcionadas e inusuales, la cual está obligando a todas las empresas a globalizar en mayor medida el ámbito de actuación de sus negocios, por lo que muchas empresas que trabajaban exclusivamente en el ámbito local o nacional han tenido que expandirse hacia el exterior. Este hecho, añadido a la fortísima competencia existente en el mercado, obligará a todas estas empresas a tener que controlar en mayor medida la actividad productiva, y a hacerlo utilizando tecnologías que faciliten el flujo de la información dentro de la empresa, hagan que la distancia no sea un problema para la transmisión de esa información, y con las que todos los usuarios manejen los mismos datos. El sector de la construcción es uno de los más castigados por la citada crisis, y probablemente uno de los más retrasados en lo que respecta a utilización de Tecnologías de la Información y la Comunicación. El objetivo principal de este trabajo es el diseño e implementación de una web dinámica como herramienta para medir la eficiencia en el control de la actividad productiva de una empresa constructora. La manera de medir esta eficiencia será mediante la comparación mensual de los costes previstos para las diferentes obras que deba ejecutar la empresa (los cuales podemos llamar estándar) y los que se vayan produciendo realmente. La herramienta diseñada podría ir aumentando su utilidad si, añadiendo módulos mediante la ampliación de la base de datos y diseñando las pertinentes nuevas páginas web para el sitio, se usa también para otros menesteres además del control de la actividad productiva por comparación entre costes previstos y reales. Es decir, que se podría llegar a gestionar la información de todas las actividades de la empresa (compras, recursos humanos, contabilidad, gestión de calidad, etc.). Por lo tanto, una web dinámica como la expuesta en el trabajo podría servir como semilla para el desarrollo de un ERP (Enterprise Resource Planning).

Distribution of neuropeptide Y Y1 receptors in rodent peripheral tissues.

Using a sensitive immunohistochemical technique, the localization of neuropeptide Y (NPY) Y1-receptor (Y1R)-like immunoreactivity (LI) was studied in various peripheral tissues of rat. Wild-type (WT) and Y1R-knockout (KO) mice were also analyzed. Y1R-LI was found in small arteries and arterioles in many tissues, with particularly high levels in the thyroid and parathyroid glands. In the thyroid gland, Y1R-LI was seen in blood vessel walls lacking alpha-smooth muscle actin, i.e., perhaps in endothelial cells of capillaries. Larger arteries lacked detectable Y1R-LI. A distinct Y1R-immunoreactive (IR) reticulum was seen in the WT mouse spleen, but not in Y1R-KO mouse or rat. In the gastrointestinal tract, Y1R-positive neurons were observed in the myenteric plexus, and a few enteroendocrine cells were Y1R-IR. Some cells in islets of Langerhans in the pancreas were Y1R-positive, and double immunostaining showed coexistence with somatostatin in D-cells. In the urogenital tract, Y1R-LI was observed in the collecting tubule cells of the renal papillae and in some epithelial cells of the seminal vesicle. Some chromaffin cells of adrenal medulla were positive for Y1R. The problem of the specificity of the Y1R-LI is evaluated using adsorption tests as well as comparisons among rat, WT mouse, and mouse with deleted Y1R. Our findings support many earlier studies based on other methodologies, showing that Y1Rs on smooth muscle cells of blood vessels mediate NPY-induced vasoconstriction in various organs. In addition, Y1Rs in other cells in parenchymal tissues of several organs suggest nonvascular effects of NPY via the Y1R.

The role of macrophage migration inhibitory factor in mouse islet transplantation.

BACKGROUND: Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine produced by many tissues including pancreatic beta-cells. METHODS: This study investigates the impact of MIF on islet transplantation using MIF knock-out (MIFko) mice. RESULTS: Early islet function, assessed with a syngeneic marginal islet mass transplant model, was enhanced when using MIFko islets (P<0.05 compared with wild-type [WT] controls). This result was supported by increased in vitro resistance of MIFko islets to apoptosis (terminal deoxynucleotide tranferase-mediated dUTP nick-end labeling assay), and by improved glucose metabolism (lower blood glucose levels, reduced glucose areas under curve and higher insulin release during intraperitoneal glucose challenges, and in vitro in the absence of MIF, P<0.01). The beneficial impact of MIFko islets was insufficient to delay allogeneic islet rejection. However, the rejection of WT islet allografts was marginally delayed in MIFko recipients by 6 days when compared with WT recipient (P<0.05). This effect is supported by the lower activity of MIF-deficient macrophages, assessed in vitro and in vivo by cotransplantation of islet/macrophages. Leukocyte infiltration of the graft and donor-specific lymphocyte activity (mixed lymphocyte reaction, interferon gamma ELISPOT) were similar in both groups. CONCLUSION: These data indicate that targeting MIF has the potential to improve early function after syngeneic islet transplantation, but has only a marginal impact on allogeneic rejection.

Signal transduction by the cloned glucagon-like peptide-1 receptor: comparison with signaling by the endogenous receptors of beta cell lines.

Glucagon-like peptide-1 (GLP-1) is a gastrointestinal hormone that potentiates glucose-induced insulin secretion by pancreatic beta cells. The mechanisms of interaction between GLP-1 and glucose signaling pathways are not well understood. Here we studied the coupling of the cloned GLP-1 receptor, expressed in fibroblasts or in COS cells, to intracellular second messengers and compared this signaling with that of the endogenous receptor expressed in insulinoma cell lines. Binding of GLP-1 to the cloned receptor stimulated formation of cAMP with the same dose dependence and similar kinetics, compared with the endogenous receptor of insulinoma cells. Compared with forskolin-induced cAMP accumulation, that induced by GLP-1 proceeded with the same initial kinetics but rapidly reached a plateau, suggesting fast desensitization of the receptor. Coupling to the phospholipase C pathway was assessed by measuring inositol phosphate production and variations in the intracellular calcium concentration. No GLP-1-induced production of inositol phosphates could be measured in the different cell types studied. A rise in the intracellular calcium concentration was nevertheless observed in transfected COS cells but was much smaller than that observed in response to norepinephrine in cells also expressing the alpha 1B-adrenergic receptor. Importantly, no such increase in the intracellular calcium concentration could be observed in transfected fibroblasts or insulinoma cells, which, however, responded well to thrombin or carbachol, respectively. Together, our data show that interaction between GLP-1 and glucose signaling pathways in beta cells may be mediated uniquely by an increase in the intracellular cAMP concentration, with the consequent activation of protein kinase A and phosphorylation of elements of the glucose-sensing apparatus or of the insulin granule exocytic machinery.

Destination image of Girona: an online text-mining approach

The main objective of this Master Thesis is to discover more about Girona’s image as a tourism destination from different agents’ perspective and to study its differences on promotion or opinions. In order to meet this objective, three components of Girona’s destination image will be studied: attribute-based component, the holistic component, and the affective component. It is true that a lot of research has been done about tourism destination image, but it is less when we are talking about the destination of Girona. Some studies have already focused on Girona as a tourist destination, but they used a different type of sample and different methodological steps. This study is new among destination studies in the sense that it is based only on textual online data and it follows a methodology based on text-miming. Text-mining is a kind of methodology that allows people extract relevant information from texts. Also, after this information is extracted by this methodology, some statistical multivariate analyses are done with the aim of discovering more about Girona’s tourism image

Establishment success and resulting fitness consequences for vole dispersers

Dispersal is one of the most important, yet least understood phenomena of evolutionary ecology. Triggers and consequences of dispersal are difficult to study in natural populations since dispersers can typically only be identified a posteriori. Therefore, a lot of work on dispersal is either of a theoretical nature or based on anecdotal observation. This is especially true for cryptic species such as small mammals. We conducted an experiment on the common vole, Microtus arvalis, in semi-natural enclosures and investigated the spatial and genetic establishment success of residents and dispersers in their natal and new populations. Our study uses genetic data on the reproductive success of 1255 individuals to measure the fitness trajectories of the residents and dispersing individuals. In agreement with past studies, we found that dispersal was highly male-biased, and was most probably induced by the agonistic encounters with conspecifics, suggesting it could act as an inbreeding avoidance mechanism. There was low breeding success of dispersers into new populations. Although nearly 26% of identified dispersers reproduced in their natal populations, only seven percent reproduced in the new populations. Settlement appeared to be a pre-requisite for reproduction in both sexes, and animals that did not spatially settle into a new population dispersed again, usually on the same day of immigration. In the event that dispersers reproduced in the new population, they did so at relatively low population densities. We also found age-related differences between the sexes in breeding success, and male dispersers that subsequently established in the new population were young individuals that had not reproduced in their natal population, whereas successful females had already reproduced in their natal population. In conclusion, with our detailed field data on establishment and substantial parentage assignments to understand breeding success, we were able to gain an insight into the fitness of dispersers, and how the two sexes optimise their fitness. Taken together, our results help to further understand the relative advantages and costs of dispersal in the common vole.
