Biogeographic and palaeoclimatic relationships of the Middle Pliocene ichthyofauna of the Samoggia Torrent (Bologna, Italy)*

New Middle Pliocene ichthyofauna (2.4-2.2 Ma) from central-eastern Italy (Samoggia Torrent, Bologna) are described. These ichthyolites were found in a rather thin laminated layer that was deposited after the 2.4 Ma climatic crisis. The origin of this deposit, in which 31 taxa have been classified, is to be related to anoxic events on a regional and, probably, supraregional scale. This ichthyofaunistic association, which consists of living genera, is characterized by a clearcut predominance of mesopelagic species. The palaeoclimatic characters of these ichthyofauna indicate subtropical-type waters, while from a palaeobiogeographic point of view there is a close relationship with the present-day Atlantic-Mediterranean bioprovince. The Samoggia deposit has yielded six taxa that are absent or only occasionally present in the Mediterranean: one of these, Spratelloides gracilis, is exclusive of the Indo-Pacific bioprovince.

Use of quantitative structure-property relationships to study the solvation process of 18-crown-6

Solution enthalpies of 18-crown-6 have been obtained for a set of 14 protic and aprotic solvents at 298.15 K. The complementary use of Solomonov's methodology and a QSPR-based approach allowed the identification of the most significant solvent descriptors that model the interaction enthalpy contribution of the solution process (Delta H-int(A/S)). Results were compared with data previously obtained for 1,4-dioxane. Although the interaction enthalpies of 18-crown-6 correlate well with those of 1,4-dioxane, the magnitude of the most relevant parameters, pi* and beta, is almost three times higher for 18-crown-6. This is rationalized in terms of the impact of the solute's volume in the solution processes of both compounds. (C) 2015 Elsevier B.V. All rights reserved.

Henri Tintant face au problème "Science et Foi"

From an early age Henri Tintant was conforted with the problematic relationships between Science and Faith. After a traditional religious education, he took responsabilities within groups of teenagers and adults through scouting and the J. E. C. (an organisation of catholic students). In 1940 he was at Montpellier distributing unauthorised leaflets defending religious faith. But more significant is his intellectual contribution. He was an active and inspiring member of several workshops and in one in particumar initiated by the Catholic University of Lyon entitled : "From Naturalist to Theologians" where he would start a very fruitful and compelling intellectual collaboration with Father Gustave Martelet a jesuit theologian and a strong supporter of a permanent dialog with the scientists. Throughout the years they will gradually come to the conclusion of a necessary synergy between the scientific and the theologic approach when dealing with the mystery of religious faith . Even in the last months of his life, Henri Tintant was writing to his friendon the subject, with the same profound religious faith that brought him the serenity and the open mindness he has showed throughout his teaching and scientific career. His legacy will remain in two of his last thoughts: "Almost 50 years of scientific research have brought me a lot of pleausures and satisfactions but no answer to the essential questions. In my personal case, science and researching have not driven me away from my religious faith, on the contrary the helped me in my awareness of its utmost necessity". "Faithful to my religious belief, I am convinced that with the death, the inevitable human destiny, not everything disapears completely but another form of live, unimaginable for our limited minds, emerges, bearing in itself the perfect realization of all our hopes and desires".

Personal learning environments: integration of Web 2.0 applications and content management systems

This paper presents an ongoing project that implements a platform for creating personal learning environments controlled by students, integrating Web 2.0 applications and content management systems, enabling the safe use of content created in Web 2.0 applications, allowing its publication in the infrastructure controlled by the HEI. Using this platform, students can develop their personal learning environment (PLE) integrated with the Learning Management System (LMS) of the HEI, enabling the management of their learning and, simultaneously, creating their e-portfolio with digital content developed for Course Units (CU). All this can be maintained after the student completes his academic studies, since the platform will remain accessible to students even after they leave the HEI and lose access to its infrastructure. The platform will enable the safe use of content created in Web 2.0 applications, allowing its protected publication in the infrastructure controlled by HEI, thus contributing to the adaptation of the L&T paradigm to the Bologna process.

Genetic relationships of Corynebacterium diphtheriae strains isolated from a diphtheria case and carriers by restriction fragment length polymorphism of rRNA genes

In the present study we report the results of an analysis, based on ribotyping of Corynebacterium diphtheriae intermedius strains isolated from a 9 years old child with clinical diphtheria and his 5 contacts. Quantitative analysis of RFLPs of rRNA was used to determine relatedness of these 7 C.diphtheriae strains providing support data in the diphtheria epidemiology. We have also tested those strains for toxigenicity in vitro by using the Elek's gel diffusion method and in vivo by using cell culture method on cultured monkey kidney cell (VERO cells). The hybridization results revealed that the 5 C.diphtheriae strains isolated from contacts and one isolated from the clinical case (nose case strain) had identical RFLP patterns with all 4 restriction endonucleases used, ribotype B. The genetic distance from this ribotype and ribotype A (throat case strain), that we initially assumed to be responsible for the illness of the patient, was of 0.450 showing poor genetic correlation among these two ribotypes. We found no significant differences concerned to the toxin production by using the cell culture method. In conclusion, the use of RFLPs of rRNA gene was successful in detecting minor differences in closely related toxigenic C.diphtheriae intermedius strains and providing information about genetic relationships among them.

Digital storytelling: student ID in higher education

Identity achievement is related to personality, as well as cognitive and interpersonal development. In tandem with the deep structural changes that have taken place in society, education must also shift towards a teaching approach focused on learning and the overall development of the student. The integration of technology may be the drive to foster the needed changes. We draw on the literature of multiple subject areas as basis for our work, namely: identity construction and self-representation, within a psychological and social standpoint; Higher Education (HE) in Portugal after Bologna, college student development and other intrinsic relationships, namely the role of emotions and interpersonal relationships in the learning process; the technological evolution of storytelling towards Digital Storytelling (DS) – the Californian model – and its connections to identity and education. Ultimately we propose DS as the aggregator capable of humanizing HE while developing essential skills and competences. Grounded on an interpretative/constructivist paradigm, we implemented a qualitative case study to explore DS in HE. In three attempts to collect student data, we gathered detailed observation notes from two Story Circles; twelve student written reflections; fourteen Digital Stories and detailed observation notes from one Story Show. We carried out three focus groups with teachers where we discussed their perceptions of each student prior to and after watching the Digital Stories, in addition to their opinion on DS in HE as a teaching and learning method and its influence on interpersonal relationships. We sought understandings of the integration of DS to analyze student selfperception and self-representation in HE contexts and intersected our findings with teachers’ perceptions of their students. We compared teachers’ and students’ perspectives, through the analysis of data collected throughout the DS process – Story Circle, Story Creation and Story Show – and triangulated that information with the students’ personal reflections and teacher perceptions. Finally we questioned if and how DS may influence teachers’ perceptions of students. We found participants to be the ultimate gatekeepers in our study. Very few students and teachers voluntarily came forth to take part in the study, confirming the challenge remains in getting participants to see the value and understand the academic rigor of DS. Despite this reluctance, DS proved to be an asset for teachers and students directly and indirectly involved in the study. DS challenges HE contexts, namely teacher established perception of students; student’s own expectations regarding learning in HE; the emotional realm, the private vs. public dichotomy and the shift in educational roles.

Genetic relationships among serogroup B: serotype 4 Neisseria meningitidis strains

We compared the results obtained by serotyping of PorB epitopes using an expanded panel of monoclonal antibodies (mAb) including mAb 7 and mAb 10, with results obtained by RFLP of rRNA genes (ribotyping). The purpose of this study was to assess the correlation between phenotypic- and genotypic- methods for typing N. meningitidis. The ribotypes obtained using ClaI or EcoRV endonucleases grouped the strains in seven and two different patterns, respectively. This additional characterization of PorB epitopes improved the correlation between these two methods of typing N. meningitidis.

Envelhecer: ser e estar - Projeto de intervenção num lar de idosos.

O presente documento reflete o percurso do desenho e do desenvolvimento de um projeto de Educação e Intervenção Social num Lar de idosos. Com base numa metodologia de Investigação-Ação Participativa, que privilegia os discursos, perceções e vivências dos atores sociais que integram esta realidade, procurou-se identificar os problemas e as necessidades. O conhecimento coconstruído com os idosos e profissionais da instituição permitiram a conceção e desenvolvimento do projeto “Envelhecer: ser e estar” que assentou, essencialmente, nas necessidades de (re) ativar e fortalecer as relações interpessoais, fomentar momentos de partilha, convívio, diálogo, discussão, negociação e participação, bem como, na urgência de envolver as pessoas na organização e ocupação do seu tempo livre promovendo a participação, o convívio e o lazer entre os idosos. Sendo um projeto das pessoas e com as pessoas, foram pensadas e planeadas ações e atividades que dessem resposta aos objetivos a que o projeto se propunha na tentativa de transformar e mudar os problemas e necessidades identificados pelos participantes. O projeto possibilitou, desta forma, iniciar um processo que permitiu fortalecer as relações entre os idosos, bem como envolvê-los na organização e participação das atividades do seu tempo livre, resultando num processo de transformação pessoal, grupal e institucional de permanente e contínua construção

Giardia lamblia and other intestinal parasitic infections and their relationships with nutritional status in children in Brazilian Amazon

The objective of this survey was to assess the relationships between intestinal parasitism, nutritional status and hemoglobin level in children with Indian ascendancy living in an urban area in Brazilian Amazon. We carried out a cross-sectional survey obtaining anthropometric, parasitological and socioeconomic data, and hemoglobin measurements of children aged six to 84 months. Anthropometric data were expressed as z-scores for weight for age (WAZ), height for age (HAZ), weight for height (WHZ) and mid upper circumference for age (MUACZ) parameters. Parasitological examinations were performed through Ritchie (n = 307), Kato-Katz (n = 278), Baermann-Moraes (n = 238) and Safranin-methylene blue methods (n = 307). Hemoglobin measurements were obtained with a Hemocue® photometer (n = 282). Socioeconomic data were used in order to classify children in three family income strata (n = 242). Multiple linear regression analysis showed independent interactions between Giardia lamblia and WAZ (beta = -0.195, SE = 0.138, p = 0.003), WHZ (beta = -0.161, SE = 0.133, p = 0.018) and MUACZ (beta = -0.197, SE = 0.143, p = 0.011), controlling for age, sex, family income, Ascaris lumbricoides, and hookworm infection. Also, the multivariate model showed that the only variable associated with hemoglobin levels was age. Intestinal parasitism control should increase children's possibilities of full development in the studied area.

Viver mais... Pensar o passado, viver o presente e sonhar o futuro Projeto de Investigação e Intervenção em Educação Social

Este relatório é o resultado descritivo e reflexivo de um Projeto de Educação e Intervenção Social, "Viver mais... Pensar o passado, viver o presente e sonhar o futuro", desenvolvido com um grupo de idosos do Centro de Caridade Nossa Senhora do Perpetuo Socorro. O projeto de investigação e de intervenção social seguiu as linhas metodológicas da Investigação Ação Participativa, em que os sujeitos são atores participativos e interventivos. Para o desenvolvimento deste projeto foi necessário recorrer a algumas técnicas de investigação, como a observação participante, conversas intencionais e análise documental, que facilitaram a recolha de informações, a análise da realidade e a intervenção desenvolvida. A partir da análise da realidade emergiram alguns problemas e necessidades que foram priorizados pelos sujeitos, daí surgiu o projeto de intervenção que aqui se apresenta com a finalidade de “Melhorar a qualidade de vida dos idosos do Centro de Dia do Centro de Caridade Nossa Senhora do Perpetuo Socorro, através da valorização das suas histórias de vida e melhoria das relações interpessoais”. Este projeto teve três grandes focos importantes que foi a recolha e construção das narrativas de vida de alguns participantes, a realização de vários encontros intergeracionais entre os idosos do Centro de Dia e as crianças do Jardim de Infância e o processo de consciencialização por parte dos idosos sobre a importância do grupo para o bem-estar pessoal, a gestão de conflitos e a melhoria das dinâmicas relacionais. Os resultados do projeto foram relevantes porque foram o produto de um processo reflexivo e de partilha entre os indivíduos, que favoreceu o desenvolvimento de um sentimento de utilidade e de valorização pessoal nos sujeitos, melhorando e fortalecendo assim as relações interpessoais entre eles.

Há Vida no Bairro! Um Projeto de Educação e Intervenção Social

O presente Relatório reflete um Projeto de Educação e Intervenção Social realizado no Empreendimento Social Padre Américo, intitulado de “Há Vida no Bairro!” que teve inicio em outubro de 2014 e, à data de escrita deste relatório, ainda se encontra em desenvolvimento. O Projeto seguiu a Metodologia de Investigação Ação Participativa tendo sido desenvolvido com os moradores do Empreendimento Social, com a finalidade de melhorar a qualidade de vida dos residentes. Partiu-se de uma análise do contexto, do bairro e dos seus moradores e, percebeu-se que existiam quatro grandes problemas: sentimentos de isolamento e de exclusão/discriminação; conflitos relacionais entre os moradores; monotonia no quotidiano das pessoas e baixos recursos económicos. Assim foram definidos dois objetivos gerais: combater os sentimentos de exclusão social dos sujeitos e promover dinâmicas relacionais satisfatórias, entre os moradores, de forma a desenvolver uma maior coesão e espírito de comunidade. Neste sentido foram definidas três ações: “Entre dedal e agulha: atelier de costura”; “O Bairro a mexer” e “Os jovens e o Bairro”. Verificou-se que os moradores do Empreendimento desenvolveram e ampliaram as suas redes de vizinhança; ocuparam o seu tempo de uma forma satisfatória; desenvolveram estratégias de resolução de conflitos; desenvolveram competências pessoais, sociais e profissionais e desenvolveram o sentimento de pertença ao bairro.
