The role of negative maternal affective states and infant temperament in early interactions between infants with cleft lip and their mothers

OBJECTIVES: The study examined the early interaction between mothers and their infants with cleft lip, assessing the role of maternal affective state and expressiveness and differences in infant temperament. METHODS: Mother-infant interactions were assessed in 25 2-month-old infants with cleft lip and 25 age-matched healthy infants. Self-report and behavioral observations were used to assess maternal depressive symptoms and expressions. Mothers rated infant temperament. RESULTS: Infants with cleft lip were less engaged and their mothers showed more difficulty in interaction than control group dyads. Mothers of infants with cleft lip displayed more negative affectivity, but did not report more self-rated depressive symptoms than control group mothers. No group differences were found in infant temperament. CONCLUSIONS: In order to support the mother's experience and facilitate her ongoing parental role, findings highlight the importance of identifying maternal negative affectivity during early interactions, even when they seem have little awareness of their depressive symptoms

An Autoethnographic Approach to Faculty Development Through a Longitudinal Analysis of a Co-taught Workshop

The present contribution explores howa co-taughtworkshop, designed and delivered in the last two academic years within two curricular disciplines of the third year of the degree course in Science of Education at University of Macerata (Italy), took advantage of autoethnography as a reflective method to enrich the interdisciplinary relationship between the two professors involved and their mutual growth in terms of instructional design and teaching practices. The exploration of Self as a data source allowed both researchers (in their teaching role) to reflect on core areas of faculty development in connection with the specific co-teaching style they adopted. Autoethnography allowed all the involved actors (students and professors) to visualize a transformative direction in their academic identity and professional growth. The discussion of the results is based on a content analysis of different data sources where all the data were triangulated in a double connotation, that is, between professors and among the different sources in an iterative process

Approccio laboratoriale e co-teaching: metodologie plurali per una formazione integrata

Il profilo professionale dell\u2019educatore socio-pedagogico prevede competenze specifiche e trasversali che lo abilitino a permanere in contesti comunitari complessi. Affinch\ue9 gli operatori possano avere una maggiore consapevolezza dei ruoli e delle funzioni di supporto dei processi educativi e delle trame sociali in cui si collocano, \ue8 essenziale che la formazione accademica garantisca loro occasioni di apprendimento cooperativo e interdisciplinare. A tal proposito, verranno descritte le line essenziali di un\u2019esperienza laboratoriale di co-teaching, evidenziando gli sfondi pedagogico-didattici che ne hanno orientato la progettazione e la realizzazione

40 Gbit/s silicon-organic hybrid (SOH) phase modulator

A 40 Gbit/s electro-optic modulator is demonstrated. The modulator is based on a slotted silicon waveguide filled with an organic material. The silicon organic hybrid (SOH) approach allows combining highly nonlinear electro-optic organic materials with CMOS-compatible silicon photonics technology

Indium phosphide based membrane photodetector for optical interconnects on silicon

We have designed, fabricated and characterized an InP-based membrane photodetector on an SOI wafer containing a Si-wiring photonic circuit. New results on RF characterization up to 20 GHz are presented. The detector fabrication is compatible with wafer scale processing steps, guaranteeing compatibility towards future generation electronic IC processing

Dinamiche-didattiche laboratoriali e spazi educativi. Logiche comunicative e assetti relazionali degli educatori in formazione

La formazione degli educatori socio-pedagogici e\u300 in continuo rinnovamento e dialogo con i luoghi della crescita personale e relazionale in cui costoro vivono e operano. Dalla famiglia agli spazi educativi, i soggetti in formazione hanno cura della propria prospetti- va professionale, grazie all\u2019attivazione di dinamiche democratiche e partecipative che li vedono muoversi in e\u301quipe e rivolgersi a contesti complessi e comunitari. In questa sede, al fine di cogliere e valorizzare la logica trasformativa della Pedagogia, e\u300 illustrata un\u2019esperienza formativa realizzata con gli studenti del Corso di Laurea in Scienze dell\u2019educazione e della formazione, ponendo in evidenza le dinamiche comunicative e gli assetti relazionali generati all\u2019interno dei piccoli gruppi di lavoro. L\u2019analisi consente di focalizzare il peso delle scelte didattiche effettuate per la conduzione dell\u2019esperienza, attraverso riflessioni pedagogiche sui significati emersi, valorizzando i vissuti e le percezioni degli studenti, in chiave progettuale, a partire dall\u2019ascolto dei loro feedback.Training of socio-pedagogical educators is being continuously renewed and open to dialogue with personal and relational spaces they live in. From family to educational settings, students take care of their own professional expectations, thanks to the activation of democratic and participatory dynamics, which make them work in teams and address community complex contexts. In order to comprehend and underline the transformative value of Pedagogy, the paper shows a training experience, run with students of the Degree Course in Education Science, in which communication and relational dynamics within the small group are highlighted. The analysis, which focuses on the impact of the didactical strategies selected for the development of the above-mentioned experience, is run through pedagogical reflections on the emerged meanings and by valorizing students\u2019 expertise and perceptions, with a design-perspective, starting from the collection of their own feedback

Silicon-organic hybrid electro-optical devices

Organic materials combined with strongly guiding silicon waveguides open the route to highly efficient electro-optical devices. Modulators based on the so-called silicon-organic hybrid (SOH) platform have only recently shown frequency responses up to 100 GHz, high-speed operation beyond 112 Gbit/s with fJ/bit power consumption. In this paper, we review the SOH platform and discuss important devices such as Mach-Zehnder and IQ-modulators based on the linear electro-optic effect. We further show liquid-crystal phase-shifters with a voltage-length product as low as V pi L = 0.06 V.mm and sub-mu W power consumption as required for slow optical switching or tuning optical filters and devices
