"Contes en família": les interaccions en un projecte de lectura compartida i dialogada en un context plurilingüe i pluricultural
Aquesta tesi es proposa analitzar com un projecte de lectura compartida i dialogada amb la participació d'infants i de les seves famílies pot afavorir el procés d’interpretació del text i l’aprenentatge de la lectura en contextos plurilingües i interculturals. Per aconseguir-ho hem dissenyat el projecte anomenat “Contes en família” i l’hem dut a terme en el context d’una escola de la ciutat de Barcelona amb infants de llengües i cultures diverses.
Partint de la concepció de la lectura com a pràctica social i afectiva, arrelada a un context històric i cultural específic, hem volgut observar de quina manera la presència costant de les llengües familiars durant l’experiència lectora, així com l’obertura a les pràctiques familiars dels participants, poden facilitar la interpretació dels textos i nodrir l’interès per llegir. Així, a partir dels conceptes de literacitats situades i plurals, ens hem preguntat com les literacitats familiars poden esdevenir “instruments” que contribueixin a la construcció d’un tercer espai; espai que veiem en costant construcció i que es situa entre l’espai oficial de l’escola i els espais no oficials dels alumnes.
Amb un enfocament metodològic qualitatiu, etnogràfic i d’estudi de casos -de tres alumnes i les seves famílies- hem desenvolupat directament les sessions del projecte “Contes en família”, hem realitzat entrevistes amb els familiars i els mestres dels infants participants, les hem enregistrat, després transcrit, i finalment a través de l’anàlisi del discurs hem interpretat les dades per donar resposta a les preguntes plantejades.
Els resultats obtinguts ens porten a remarcar la importància de l’aprenentatge de la lectura com a procés mediat cognitivament, afectivament i lingüísticament. Seguint la proposta de lectura transaccional i interactiva elaborada per Terwagne, Vanhulle, i Lafontaine (2003), hem pogut comprovar la importància de la presència d’un dinamitzador que exemplifica les estratègies d’interpretació i d’interacció, per tal que els alumnes les interioritzin gradualment i les facin servir en les discussions amb els seus companys.
Els resultats també mostren que la presència i col·laboració dels pares en el procés de lectura suporten la motivació a la lectura per part dels nens; en particular, hem pogut observar com la proximitat física, la mirada atenta i el diàleg constant, sobretot amb els propis familiars, proporcionen un suport emocional a la perezhivanie (Vygotsky) dels infants que sosté el procés lector.
Des del punt de vista lingüístic, hem observat que l’ús del llenguatge híbrid fa que hi hagi un accés permanent als recursos lingüístics, culturals i cognitius dels altres. D’aquesta manera l’ús de les llengües, i en general de totes les literacitats locals dels alumnes, es revelen com a instruments de mediació per a la construcció del coneixement, alhora que faciliten l’apropiació del discurs de l’escola que és necessari per al progrés escolar. Així, l’experiència de lectura compartida i dialogada amb la participació de la família promou la pràctica de la mediació i de la hibridació que, al seu torn, afavoreixen el procés lector.
Els resultats també mostren de quina manera el fet d’ampliar el model convencional de relacions entre escola i família, com ara oferint un espai de lectura compartida, pot incidir en part sobre la participació dels pares a l’escola. Es fa evident la necessitat per part del pares de comprendre el funcionament d’un sistema escolar que no els és familiar; i per part de l’escola la necessitat d’obertura a les famílies per comprendre i incloure les seves literacitats.The aim of this work is to analyse how a shared reading project with the participation of children and their families can favour learning to read in multilingual and intercultural contexts. To achieve this purpose, we have designed the project "Contes en família" and we have carried it out in the context of a school in Barcelona with children of different languages and cultures.
Starting from the conception of reading as a social and emotional practice, rooted in a specific historical and cultural context, we wanted to observe how the constant presence of family literacies during the reading experience can facilitate the interpretation of the texts and nurture the interest to read. Thus, from the concepts of situated and plural family literacies, we have asked ourselves how family literacies can become "instruments" that contribute to the construction of a third space; a space that we see as in constant construction and that is situated between the official space of the school and the unofficial spaces (environments) of the students.
Under a qualitative, ethnographic methodological and case study approach -three students and their families- we have directly developed the sessions of the "Contes en família" project; interviewing the relatives and teachers of the participating children, recording the sessions and transcribing them, and lastly answering the questions posed through discourse analysis and interpretation of the data.
The results obtained emphasize the importance of learning to read as a cognitive, emotional and linguistically mediated process. We have been able to verify the importance of the presence of a facilitator who exemplifies the strategies of interpretation and interaction. The results also show that the presence and collaboration of parents in the reading process provide an emotional support to children that sustains the reading process. From a linguistic point of view, we have observed that the use of hybrid language (and the local literacies of the students in general), is an important instruments of mediation for the construction of knowledge; at the same time it facilitates the appropriation of the school’s discourse which is necessary for the school progress. The results also show how broadening the conventional model of school-family relationships, such as offering a shared reading space, may have an impact on parental involvement in school
L’educare dei padri con figli/e disabili. Riflessioni pedagogiche e progetto di ricerca
This paper illustrates some theoretical issues about the fatherhood and its transformations by examining definitions and descriptions of fathering within the educational filed. Starting from thisbackground, the paper shows some questions underpinned of a research project about the role of the father in a family with a disabled son/daughter. Fathers influence the develop of their disabledchild directly through their behaviour and attitudes. Focusing on fathers’ role, we try to reflect about “which roles do fathers play in family life today and which dimensions could characterize father’s educational functions?” in order to support, from an educational perspectives, fathers in their pathway with a disabled child
Robotic total gastrectomy with intracorporeal robot-sewn anastomosis. A novel approach adopting the double-loop reconstruction method
Gastric cancer constitutes a major health problem. Robotic
surgery has been progressively developed in this field. Although the
feasibility of robotic procedures has been demonstrated, there are
unresolved aspects being debated, including the reproducibility of
intracorporeal in place of extracorporeal anastomosis.
Difficulties of traditional laparoscopy have been described and there
are well-known advantages of robotic systems, but few articles in
literature describe a full robotic execution of the reconstructive phase
while others do not give a thorough explanation how this phase was run.
A new reconstructive approach, not yet described in literature, was
recently adopted at our Center.
Robotic total gastrectomy with D2 lymphadenectomy and a socalled
‘‘double-loop’’ reconstruction method with intracorporeal robotsewn
anastomosis (Parisi’s technique) was performed in all reported
cases.
Preoperative, intraoperative, and postoperative data were collected
and a technical note was documented.
All tumors were located at the upper third of the stomach, and no
conversions or intraoperative complications occurred. Histopathological
analysis showed R0 resection obtained in all specimens. Hospital
stay was regular in all patients and discharge was recommended starting
from the 4th postoperative day. No major postoperative complications
or reoperations occurred.
Reconstruction of the digestive tract after total gastrectomy is one of
the main areas of surgical research in the treatment of gastric cancer and
in the field of minimally invasive surgery.
The double-loop method is a valid simplification of the traditional
technique of construction of the Roux-limb that could increase the
feasibility and safety in performing a full hand-sewn intracorporeal
reconstruction and it appears to fit the characteristics of the robotic
system thus obtaining excellent postoperative clinical outcome
Characterization of Five Psychrotolerant Alcanivorax spp. Strains Isolated from Antarctica
Five psychrotolerant Alcanivorax spp. strains were isolated from Antarctic coastal waters. Strains were screened for molecular and physiological properties and analyzed regarding their growth capacity. Partial 16S rDNA, alk-B1, and P450 gene sequencing was performed. Biolog EcoPlates and the API 20E test were used to evaluate metabolic and biochemical profiles. Bacterial growth in sodium acetate was determined at 4, 15, 20, and 25 °C to evaluate the optimal temperature. Furthermore, the ability of each strain to grow in a hydrocarbon mixture at 4 and 25 °C was assayed. Biosurfactant production tests (drop-collapse and oil spreading) and emulsification activity tests (E24) were also performed. Concerning results of partial gene sequencing (16S rDNA, alk-B1, and P450), a high similarity of the isolates with the same genes isolated from other Alcanivorax spp. strains was observed. The metabolic profiles obtained by Biolog assays showed no significant differences in the isolates compared to the Alcanivorax borkumensis wild type. The results of biodegradative tests showed their capability to grow at different temperatures. All strains showed biosurfactant production and emulsification activity. Our findings underline the importance to proceed in the isolation and characterization of Antarctic hydrocarbon-degrading bacterial strains since their biotechnological and environmental applications could be useful even for pollution remediation in polar areas

Intersigmoid hernia. A forgotten diagnosis, a systematic review of the literature over anatomical, diagnostic, surgical, and medicolegal aspects
Introduction. Intersigmoid hernia is a hernia of the small bowel into the intersigmoid fossa. It is well known to be a rare
condition. Recent reports reveal that the preoperative differentiation of intersigmoid hernias is difficult and the diagnosis is
often confirmed during the laparotomic exploration. Due to the vague clinical manifestation in most cases, the surgical
treatment is frequently delayed. Materials and Methods. In this study, we systematically reviewed the literature up to 2019
covering 114 studies and 124 patients with an intersigmoid hernia. &e purpose of this work is to improve the understanding of
the anatomical aspects, clinical presentation, diagnosis, and treatment of intersigmoid hernia so as to assist the preoperative
differentiation of these hernias when presented as acute abdomen in the emergency department. Results. &e diameter of the
intersigmoid recess was reported with mean 2.65 cm (range 1–10 cm, SD 1.15 cm) and the length of the incarcerated small
intestine was between 3 cm (min) and 150 cm (max): mean 25.25 cm, SD 35.04 cm. &e diameter of the sigmoid recess was
greater in patients who underwent resection due to strangulation (mean 3.31 cm, SD 1.53 cm) compared to those who underwent
only reduction of the hernia (mean 2.35 cm, SD 0.74 cm). &e time from onset to operation was less in patients
undergoing resection surgery due to throttling (mean 3.03 days, SD 3.01 days) compared to those who underwent only a
reduction of hernia incarceration (mean 8.49 days, SD 6.83 days). Conclusion. Intersigmoid hernia is often a forgotten diagnosis
and a clinical challange due to its anatomical characteristics
Temporary dense seismic network during the 2016 Central Italy seismic emergency for microzonation studies
In August 2016, a magnitude 6.0 earthquake struck Central Italy, starting a devastating seismic sequence, aggravated by other two events of magnitude 5.9 and 6.5, respectively. After the first mainshock, four Italian institutions installed a dense temporary network of 50 seismic stations in an area of 260 km2. The network was registered in the International Federation of Digital Seismograph Networks with the code 3A and quoted with a Digital Object Identifier ( https://doi.org/10.13127/SD/ku7Xm12Yy9 ). Raw data were converted into the standard binary miniSEED format, and organized in a structured archive. Then, data quality and completeness were checked, and all the relevant information was used for creating the metadata volumes. Finally, the 99 Gb of continuous seismic data and metadata were uploaded into the INGV node of the European Integrated Data Archive repository. Their use was regulated by a Memorandum of Understanding between the institutions. After an embargo period, the data are now available for many different seismological studies.Publishedid 1825T.

Does spatial locative comprehension predict landmark-based navigation?
In the present study we investigated the role of spatial locative comprehension in learning and retrieving pathways when landmarks were available and when they were absent in a sample of typically developing 6- to 11-year-old children. Our results show that the more proficient children are in understanding spatial locatives the more they are able to learn pathways, retrieve them after a delay and represent them on a map when landmarks are present in the environment. These findings suggest that spatial language is crucial when individuals rely on sequences of landmarks to drive their navigation towards a given goal but that it is not involved when navigational representations based on the geometrical shape of the environment or the coding of body movements are sufficient for memorizing and recalling short pathways
