L'ús dels clítics pronominals del català i la seva adquisició per parlants de romanès i de tagal

El nostre estudi ha analitzat els mecanismes de transferència de la L1 en dos grups de parlants, un que té el romanès i l’altre el tagal com a llengües mare, en el procés d’aprenentatge del català com a L2. En concret ens hem centrat en l’estudi de l’ús dels clítics pronominals, una de les parts de la gramàtica catalana més apassionant per les seves idiosincràsies i la seva diversitat formal. L’ús d’aquest tipus de pronoms és un aspecte que resulta complicat d’adquirir per parlants de llengües en què no existeixen o on l’ús que en fan és diferent. En el nostre estudi, ens hem basat inicialment en la descripció de les característiques fonamentals dels clítics pronominals del català, del romanès i del tagal, a partir de bibliografia especialitzada i més general, i, en el cas del català, fent servir també la pròpia competència. Després d’aquest apartat més descriptiu, hem utilitzat un corpus d’entrevistes fetes en català a dos grups de parlants, el primer amb aprenents de català que tenen el romanès com a L1 i el segon amb aprenents de català que tenen el tagal com a L1, per analitzar quantitativament i qualitativament l’ús dels clítics pronominals. Un altre grup d’entrevistes, aquesta vegada a persones autòctones (català L1), ens ha servit com a grup de control. El nostre estudi dóna suport a la hipòtesi que atorga una importància especial a la transferència de la L1 en l’adquisició d'una segona llengua en general, i en la dels clítics pronominals d’una llengua romànica, en particular. Els resultats mostren que hi ha diferències entre els dos grups d'aprenents que són estadísticament significatives (ús del programa SPSS) i poden ser atribuïdes a les característiques de la L1.

The learning process as a cooperative task among teachers and students

This research project gathers several ideas and guidelines on professional improvement as a teacher. This study includes two empirical studies. The first one focuses mainly on the teacher's figure. It is meant to be a study of the several resources that the teacher uses in order to construct the student's knowledge in an English classroom context. The second empirical study focuses on the students. It is a study on how students learn cooperatively by analyzing their oral productions when working in small groups

Nematode parasites of Brazilian piciformes birds: a general survey with description of Procyrnea anterovulvata n. sp. (Habronematoidea, Habronematidae)

Thirty species of nematodes recovered from Piciformes hosts are reported. Procyrnea anterovulvata n. sp. from Chelidoptera tenebrosa brasiliensis is described and compared to P. colaptes and P. pileata. The considered morphometric parameters are mainly related to the ratio between length of the body/distance of the vulva to the anterior end. It is approximately 1:0.5 in P. colaptes and P. pileata compared to 1:0.1 in the new species. The male of Synhimantus (Dispharynx) crassissima is described for the first time. Thelazia (Thelaziella) spizaeti is revalidated and new records are reported for some species.

Adaptació del model europeu (EEES) de les assignatures relacionades amb organització i mètodes de treball de la Diplomatura de relacions Laborals

L'adaptació dels estudis a l'Espai Europeu d'Educació Superior (EEES) comporta l'establiment d'un nou paradigma docent centrat en l'estudiant, l'ús d'una nova unitat de valoració de l'activitat acadèmica, el crèdit europeu, i enfortir i repensar l'avaluació de l'aprenentatge. Aquesta adaptació representa una transformació profunda en el paper que juga tant el professor com l'alumne. En aquest context, es fa molt necessari adaptar les metodologies docents, els continguts i les eines d'interacció amb els alumnes. La finalitat d'aquest projecte consisteix en adaptar les assignatures troncals d'Organització i Mètodes de Treball de la Diplomatura de Relacions Laborals a aquest nou entorn. Per a tal fi, a part d'elaborar un pla docent consistent al EEES, també s'han de desenvolupar continguts, eines d'interacció i metodologies d'avaluació que permetin millorar el nivell de formació i el rendiment acadèmic de l'estudiant. Aquest projecte comprèn sis accions específiques per aconseguir-ho: 1) L'elaboració de la guia docent (objectius, capacitats a treballar, continguts, metodologia, avaluació, etc.); 2) L'elaboració del programa d'activitats (on es concreten les activitats d'aprenentatge que l'estudiant ha de dur a terme per assolir els objectius formatius: projectes tutoritzats, estudis de casos , lectures orientades, etc.) 3) Elaboració del material teòric. Aquesta acció té com a objectiu realitzar un llibre bàsic que comprengui la totalitat de la matèria relacionada amb OMT. 4) Elaboració del material pràctic. 5) Creació d'una pàgina web per aquest material. Aquesta web pretén ser un espai de treball comú pels estudiants de Relacions Laborals que cursin assignatures d'OMT a la UAB i la UPF. 6) Realitzar un projecte pilot tutoritzat. Aquesta prova pilot sorgeix arran de converses informals mantingudes amb alumnes de la diplomatura i la coordinadora d'estudis.

Description of the Occurrence of Canine Dirofilariasis in the State of Rio de Janeiro, Brazil

In order to evaluate the prevalence of canine heartworm in the State of Rio de Janeiro, a multicenter survey was carried out in two phases. The survey involved 1376 dogs from two cities: Rio de Janeiro and Niterói, and its surroundings, including the eastern shore and mountain resorts, which were further divided into sections. In the first phase, 795 dog blood samples were examined by the modified Knott test for the detection of microfilariae. A total of 134 samples (16.85%) were microfilaremic: 8.61% from Rio de Janeiro, 21.76% from Niterói and its surroundings, 33.33% from the eastern shore and 30.43% from the mountain resorts. In the second phase, 595 dog blood samples were examined first by the modified Knott test and the amicrofilaremic samples were subsequently examined by an immunoenzymatic test (ELISA) for antigen detection. In summary, 83 samples (13.95%) were microfilaremic and 44 (7.98%) of the amicrofilaremic samples were positive for heartworm antigen (occult infections). In Rio de Janeiro, 13.68% of the dogs were infected (i.e., antigen-and/or microfilaria-positive) and 8.51% of the dogs had microfilaremic infections. In comparison, Niterói and its surroundings showed values of 24.46% and 17.30% and the eastern shore showed values of 52.46% and 31.15%. In contrast the mountain resorts showed 20% microfilaremic only

Viktorocara brasiliensis n. sp. is proposed and compared with V. capillaris, V. limosae, V. charadrii and V. garridoi which are the other species included in the genus. The differentiation of V. brasiliensis n. sp. was based on the ratios between muscular and glandular esophagus and spicules, as well. Other referred species are Acuaria mamillaris, A. mayori, Aprocta sp., Cheilospirura sp., Diplotriaena americana, D. bargusinica, Oxyspirura matogrosensis, Oxyspirura sp., Pelecitus helicinus, Procyrnea sp., Skrjabinura spiralis, Subulura papillosa, Synhimantus sp. and Tetrameres (Microtetrameres) sp., with the establishment of some new host records

Description of the Immature Stages of Anopheles (Nyssorhynchus) rondoni (Neiva & Pinto) (Diptera: Culicidae)

The larval and pupal stages of Anopheles (Nyssorhynchus) rondoni (Neiva and Pinto) (Albimanus Section) are fully described and illustrated for the first time. The larval stage is similar to An. (Nys.) strodei Root. It can be recognized by the following combination of characters: clypeal index, 1.6-2.9; single, aciculate setae 2,3-C; seta 3-C 0.5-0.7 the length of 2-C; setae 1,2-P rarely sharing a common tubercle; seta 1-P with narrow leaflets. The pupal stage is distinguished from other Nyssorhynchus by having setae 1-IV-VII and 5-V-VII branched. Only minor variation was found in setal counts between specimens from Peixoto de Azevedo, State of Mato Grosso and Bocaina, State of São Paulo, Brazil

The role of the object and the mourning process in the child

The young child's ability to go through a genuine mourning process has been a source of controversy in the psychoanalytical literature. This may seem surprising, considering that mourning is essential for and inherent to psychic development. This paper attempts to show that the young child's ability to go through a mourning process does not depend mainly on ego maturity, nor just on an acknowledgment of a loss in the external world, nor on the child's understanding the idea of death at an intellectual and cognitive level. But it may depend mainly on the establishment of the primordial mourning process inherent to the separation of the transnarcissistic mother-child relation and on the existence of the objectalizing function (A. Green, 1986) in the remaining or substitute parent's psyche. A clinical example serves to illustrate these hypotheses.

Description of an in vivo model for the assessment of eosinophil chemoattractants in the mouse

Chemokines (chemoattractant cytokines) induce potent and selective chemotaxis of leukocyte subsets in vitro. Here, we review briefly the chemokines shown to induce eosinophil chemotaxis in vitro and describe a novel model for the study of the ability of chemokines to stimulate eosinophil migration in vivo. Eosinophils were purified from the blood of mice over-expressing the IL-5 gene and labelled with 111In. Only the C-C chemokines, eotaxin and MIP-1alpha, but not RANTES, MCP-1, MCP-3, MCP-4, MIP-1ß, KC and MIP-2, effectively induced the recruitment of 111In-eosinophils in mouse skin. We suggest that this mouse model will be useful in assessing the role of endogenously-generated chemokines in mediating eosinophil migration to sites of allergic inflammation in vivo.
