Non trivial chiroptical responses: experimental and theoretical investigations
No full textIn the past few years, our two groups of research have been collaborating on a number of projects
dealing with the assignment of the absolute configuration (AC) of complex chiral molecules of phar-
macological interest in the disordered phase. [1] These studies have been mainly carried out by means of
electronic circular dichroism (ECD) spectroscopy and quantum mechanical (QM) calculations at the den-
sity functional theory (DFT) level of approximation. Particular attention has been payed to non-trivial
chiroptical responses due to conformational flexibility and solvation.
Beside these shared activities, some more specific research fields have been investigated too. In par-
ticular, the Bologna group has performed studies concerning the hyphenation of enantioselective HPLC
methods with detection systems based on ECD [2] and the characterization of biomolecular recognition
phenomena between drugs and target or carrier macromolecules. [3] The Salerno group has developed
some skills in vibrational circular dichroism (VCD) [4] and chiral NMR [5] spectroscopies, thanks to the
availability of a VCD spectrometer and previous studies concerning the non-linear response of molecules
exposed to radiation.

Reich und Heimat: zur Semantik im deutschsprachigen Raum
No full textIl saggio - nato nell’ambito di un progetto di ricerca sulla Mitteleuropa (Università TU Dresden, Paris III, L’Orientale di Napoli / Programma Villa Vigoni) - è centrato sui concetti di Reich e Heimat, che indicano sistemi sovranazionali e costituiscono fondamentalmente i due poli tra cui si giocano le sorti del mondo mitteleuropeo; entrambi i concetti vengono ripensati nelle loro diverse valenze sul piano storico, geopolitico, culturale, simbolico.
Viene altresì analizzato lo stesso concetto estremamente complesso di Mitteleuropa, anche alla luce di recenti studi di rilievo (J. Le Rider, K. Schlögel), con particolare focus su alcuni ‘discorsi’ contrapposti, dall’utopia ‘retrospettiva’ delle tradizioni mitteleuropee coltivata dall’intellettualità dissidente dell’Est negli anni Ottanta fino alla radicale demistificazione del ‘mito asburgico’ negli scritti di K. M. Gauß.
L’A. sottolinea, infine, la nuova fortuna dell’idea di patria, che include dimensioni spazio-temporali, ma anche molteplici componenti socio-culturali, affettive e simboliche connesse all’identità. Suggestiva, sotto il profilo letterario, l’identificazione della patria nel linguaggio (Sprachheimat), che – considerando l’attuale panorama della letteratura di lingua tedesca – consente uno sguardo in prospettiva e non solo postumo sul patrimonio storico-culturale della Mitteleuropa

Crescere con un solo genitore: studenti nativi e immigrati a confronto.
No full textChi cresce con un solo genitore ha risultati scolastici peggiori, ma
ci sono differenze a seconda del background migratorio? In un recente studio su studenti di scuola media in Italia, Raffaele Guetto, Francesca Zanasi, e Maria Carella, mostrano come gli studenti italiani siano più svantaggiati dall’assenza di un genitore rispetto a quelli immigrati. Lo studio ricerca i motivi della differenza nelle risorse a disposizione delle famiglie e nel motivo di assenza genitoriale

Sustainable Relations in International Development Cooperation Projects: The Role of Human Resource Management and Organizational Climate
No full textThe importance of organizational issues to assess the success of international development project has not been fully considered yet. An analysis of the literature on the project success definition, focused on the success criteria and success factors, was carried out by surveying the contribution of different authors and approaches. Traditionally projects were perceived as successful when they met time, budget and performance goals, assuming a basic similarity among projects (universalistic approach). However, starting from a non‐universalistic approach, the importance of organization’s effectiveness, in terms of relations sustainability, emerged as a dimension able to define and assess a project success (Belassi W., Tukel O.I., 1996). Based on previous research contributions on the factors influencing the relations between organizations (Zanasi C., Rota C., 2009), the paper expands the analysis of the influence of human resource management on organizational climate that, in turn, influences the relation sustainability between project manager and project team involved in international cooperation for development. A detailed analysis of these relations is provided and a research hypothesis are built. A questionnaire on previous contributions was adapted to collect data for a Structural Equation Modelling (SEM) analysis. Five dimensions of organizational climate (Zeitz G. et al., 1997) (trust, communication, innovation, job challenge, social cohesion), four dimensions of human resource management (Snell S.A., Dean J.W, 1992) (staff recruitment, training, performance appraisal, reward system) and two dimension for sustainable relations (Fisher C., Reynolds N., 2008) (relations quality and strength) are reported and measured by using a 5 point Likert scale. The sample size is still in progress. The first results on internal consistency reliability coefficients (Cronbach’s alpha) are satisfactory
