Children of lesbian parents: A research on family triadic interactions

Background: Literature on relational dynamics in lesbian headed families (Bos, et al. 2007; Goldberg, 2009; Chan, et al. 1998) focuses on intergenerational relationships using mainly self-report scales. Only few researches adopt an observational methodology aimed to study family interactions. Our preliminary study is aimed to observe through the Lausanne Trilogue Play (Fivaz-Depeursinge, Corboz-Warnery1999) postnatal family interactions of lesbian headed families. We expect a good internal correlation of LTP scales and a distribution of family alliances similarly to other non-referred families. Method: 10 non-clinical lesbian families procreating through medically assisted procreation (IVF). Families were recruited through associations and forums. The Lausanne Trilogue Play paradigm (LTP Fivaz-Depeursinge, 1999) is coded using Family Alliance Assessment Scale (Favez et al, 2008). Average age: biological mothers 34,4 (Ds: 5, 85); not biological mother 36,6 (Ds: 7,69) and childrens 28,3 months (Ds: 22,08)

Pharmaceutical applications of biocompatible polymer blends containing sodium alginate

Biocompatible polymer blends, such as alginate blends, have a widespread use in pharmaceutical and medical applications due to their specific features, such as biodegradation, adhesiveness, and thermo- and pH sensitivity and that can be obtained from the mixture composition. In this work, the use of alginate blends was tested in a novel production methodology of therapeutic dosage forms based on polymeric chain reticulation phenomena induced by exposure to bivalent ions. Two kinds of sodium alginate were used to obtain gel films (structured films) in blends with Pluronic F127\uae. The blends were considered for applications in gel paving of drug-eluting stents. Sodium alginate was also used in shell\u2013core particle production (structured particles) to obtain shell-barrier reducing drug release in the preparative steps (see wash operations). Both structures, films and particles, were obtained using Cu2+ and Ca2+ ions, respectively. Film/shell barrier properties were tested in dissolution experiments using vitamin B12 as an active molecule model. Experimental work demonstrated that the alginate composition is a crucial point in defining reticulated structures

Il ruolo dell\u2019epistemologia dell\u2019insegnante nelle pratiche d\u2019insegnamento

There are different epistemologies that take part into the didactic action; for this reason an aware and significant epistemological training plays an extraordinary role in teachers\u2019 training. Concepts like milieu and obstacles (epistemological and didactical) work out to be useful for such training. In this work we deal with this issue and we provide significant examples that show how a defective epistemological preparation negatively influences the classroom action. In this ambit, the didactical contract is also taken into account
