No full textVengono presentati i primi risultati dell’indagine sugli sbocchi occupazionali dei laureati del Corso di laurea quadriennale in Scienze dell'educazione, con i suoi tre indirizzi (Insegnanti di scienze dell'educazione, Educatori professionali, Esperti nei processi formativi) svolta nel quadro del progetto dell’Ateneo patavino inteso a monitorare longitudinalmente, nell’arco di tre anni, l’esito della propria offerta formativa. La ricerca è stata stimolata dalla accresciuta domanda di figure educativo-formative legata alla crescita della domanda di servizi educativi alla persona e alla comunità, e all'ampliarsi e articolarsi dei bisogni di formazione iniziale e continua delle risorse umane, e dalla conseguente necessità di definire i profili professionali richiesti dai nuovi scenari sociali e culturali

A novel environmental indicator for monitoring of pesticides
No full textThe identification of an indicator for monitoring pesticides is a very effective analytical approach because it allows one to schedule and simplify the analytical routine. In this study, a new indicator has been designed, which has to be able to define a scale of priorities in the pesticides monitoring. A starting equation was developed involving the escaping tendency of a given substance from a phase (based on the Mackay model I level). The reliability of the indicator was tested by application to a model system, consisting of a defined and limited area, choosing water as matrix over a period of 6 years. A group of marker compounds was also defined to implement the predictive efficacy of the indicator. The results obtained by modeling were compared to those obtained by experimentation of the same model system. The indicator was subsequently and appropriately modified creating a new equation, including a kinetic factor, which considers the environmental degradation processes. The effect of the rectified indicator was consistent with the sales data list of compounds, when applied to the markers. The indicator developed in this study, tested as a model on specific area-phase-period (Province of Siena, water phase, 2000-2006), is applicable to any other area-phase-period, adjusting the partition value of the Mackay model for the case under study. © 2010 Springer Science+Business Media B.V

No full textBuilding and sharing teacher professional identity in virtual communities
No full textThe main objective of the present research is the elaboration and validation of online workshop models aimed at the university training of primary school teachers. The research was carried out over two year period (the 2005-06 and 2006-07 academic years) in the University of Padova. Two different types group of students were involved, pre-service and the in-service (professional beginner and advance beginner) teacher students. Collaborative casework activities were offered to all students who attended online workshops with direct reference to Communities of Inquiry by David R. Garrison and Terry Anderson (2003). The research was based on integrated mixed methodology: multi strands multi methods (Teddlie and Tashakkori, 2005). The data, provided from pre-post individual activities (profile protocols) and forum’s activities (forum protocols), was analysed using quantitative approaches (specificity and correspondence analyses etc.) and quantitative-qualitative approach (protocols of forums) using categories of David R. Garrison and Terry Anderson (2003; Garrison et al, 2006), Helen L. Harrington (Harrington et al, 1996), Richard F. Bales (1950; 1970) revisited and analysed by new “integrated” SNA model, and narrative interviews made with selected beginners and advanced-beginners teachers students. The results obtained confirm effectiveness of online workshop models only for student and beginner teachers, and also a tendency towards a functional fixedness and self-reference of in service teacher students, especially in advanced teachers students. The positive results of narrative interviews carried out also confirmed an increased awareness and deeper comprehension of personal and professional identity in the involved subjects. These results lead us to consider the prospect of a new model of teacher education that may be promising especially for the advanced-beginner teachers and other levels of competent or expert teachers, categories which have proven to be the most resistant to professional identity conceptual changes
An integrated assessment of energy conversion processes by means of thermodynamic, economic and environmental parameters
No full textA comprehensive method of analysis based on energetic, exergetic, economic and emergetic evaluations is proposed and presented in the paper. Emissions to the environment are also considered. Suitable indicators developed within a methodological framework are defined and discussed according to the previous aspects.
In the authors’ opinion, by performing and comparing all of these evaluations, valuable information about plant performances can be obtained. This can be helpful in the decision making process. The method proposed here is addressed to policy makers and operators and possibly designers working in the field of energy supply and conversion.
Some results from the application to selected plants (hydroelectric, ethanol production and thermoelectric) are presented and compared and general considerations about the effectiveness of different approaches are suggested
Impact of the invasive painted bug Bagrada hilaris on physiological traits of its host Brassica oleracea var botrytis
No full textBagrada hilaris is a herbivorous insect native of Asia and Africa, which has invaded southern Europe and North America where it causes major damage to cole crops. Laboratory experiments were conducted to assess how the infestation of this invasive species damages the host Brassica oleracea var botrytis, and to evaluate the interaction between plant emission of volatile organic compounds (VOC) and B. hilaris adults. Plant responses to insect feeding were evaluated through changes in photosynthesis, stomatal conductance, VOC emission, and visual damage on leaves. The impact of B. hilaris was compared with that of Nezara viridula, a polyphagous species distributed worldwide. Plant VOC role in host plant detection was tested with electroantennography bioassays on B. hilaris antenna. Photosynthesis and stomatal conductance were consistently reduced in plants infested with 40 B. hilaris adults for 24 h. The feeding activity of a single B. hilaris caused larger discolored spots on host leaves in comparison with N. viridula. VOC emitted by B. oleracea changed significantly in response to B. hilaris and N. viridula infestation. In particular, production of limonene was strongly reduced by the infestation of the two pentatomids, while an increase in the emission of acetic acid and 2-ethyl-1-hexanol was observed. EAG dose–response tests using the main plant VOC showed B. hilaris antennal responses to benzaldehyde, octanal, nonanal, and acetic acid, which indicates a role of these compounds in host location
