Complexity in interlanguage usage and development: investigating the dictogloss task
No full textThis paper reports on a small case study aimed at exploring interlanguage complexity in language- related episodes during a collaborative output task (dictogloss). The study involved a group of EFL intermediate level students. Our investigation sought to unravel interlanguage complexity from different perspectives: usage and development. The analytical framework was provided by usage-based approaches (construction grammar and complexity theory) which enabled us to operationalize complexity in terms of heterogeneity, non-linearity and co-adaptation. Data analysis highlighted the key role of the ‘restructuring’ stage of the task with its open dynamic structure which encouraged learners to adapt and develop their linguistic resources in response to the affordances that emerged in the communicative context provided by the task
EU Regional and Urban Policy Innovations and Experiences from the 2014–2020 Programming Period
No full textThe book critically reflects on some of the most important novelties and experimentations in the context of the European Union’s renewed urban and regional policy in the last programming period, 2014-2020. In particular, it examines four main innovations characterizing this period, which emerged as a result of the deep rethinking and reorganization of Cohesion Policy in the spirit of the place-based approach to local development, i.e. the development of the smart specialization strategy, the establishment of macro-regions, the focus on the urban dimension as a horizontal priority, and the role of social innovation in urban policy. Unlike other similar books, it analyzes the urban dimension of the reformed EU cohesion policy, especially focusing on its interplay with the regional dimension, and which has not been fully addressed to date. The book is intended for social scientists engaged in research on European issues, especially from regional and urban perspectives, policy-makers, particularly at the local level, and graduate students interested in regional and urban European matters
Castleman's disease in childhood: a case report
No full textWe report a case of Castleman's disease in 3-month old infant with cervical swelling, treated with surgical excision. This case is interesting because of the rarity of this disease in childhood, of the cervical localization and of the complexity of long- term follow-up
Sindrome delle apnee ostruttive notturne : sono sempre causa di non idoneità a mansioni complesse?
No full textThe author, after an analysis of the statistical data on work-related diseases reported to the INAIL and listed on the Annual Report 2007, examines the main highlights of the "new tables of professional diseases in industry and agriculture" published in the Ministerial Decree of July 21st, 2008 (GU n.169, 21-7-2008), also relating to the introduction of musculoskeletal disorders of the upper limb due to bio-mechanical strain into the list of professional diseases to which the legal presumption of origin is applicable
Electrochemically controlled assembling/disassembling processes with a bis-imino bis-quinoline ligand and the CuII/CuI couple
No full textThe bis-iminoquinoline quadridentate ligand L is capable of forming air- and moisture-stable complexes both with Cu-II and Cu-I; thus the L/Cu-II/I set is a bistable system. Owing to its quite rigid preorganized structure, L forms the 1:1 complex [(CuL)-L-II](2+) when binding the d(9) cation Cu2+, while with the d(10) cation Cu+, dimeric complexes of the [(Cu2L2)-L-I](2+) type are formed in which each copper cation is coordinated by two iminoquinoline fragments belonging to two different ligands. Crystal and molecular structure determinations showed that, in [(CuL)-L-II](CF3SO3)(2), L binds to the metal center in a square-planar fashion, while in [(Cu2L2)-L-I](CF3SO3)(2) the Cu+ cations are coordinated with a tetrahedral geometry, with the two ligands L intertwined in a double helix. On the other hand, in the case of [(Cu2L2)-L-I](ClO4)(2) both a helical species and a dimeric nonhelical one were found to coexist in the same crystal cell. However, spectrophotometric and H-1 NMR studies demonstrated that, in acetonitrile solution, only two helical forms exist, one of which is more prevalent (87%, at 20 degrees C). The interconversion equilibrium between the two helical forms has been studied in acetonitrile by temperature variable H-1 NMR and the pertinent Delta H-circle minus and Delta S-circle minus values have been determined; these account for the small difference in energy between the two species. Finally, cyclic voltammetry and spectroelectrochemical experiments demonstrated that in acetonitrile solution it is possible to rapidly transform [(CuL)-L-II](2+) into the helical [(Cu2L2)-L-I](2+) dimer (or vice versa) by changing the potential applied to the working electrode, that is, it is possible to electrochemically control the self-assembly/disassembly process through the Cu-II/Cu-I redox couple. Moreover, it has been shown that self-assembly (reduction)/disassembly (oxidation) cycles can be repeated at will, without any degradation of the system
A Fusion between Domains of the Human Bone Morphogenetic Protein-2 and Maize 27 kD γ-Zein Accumulates to High Levels in the Endoplasmic Reticulum without Forming Protein Bodies in Transgenic Tobacco
No full textHuman Bone Morphogenetic Protein-2 (hBMP2) is an osteoinductive agent physiologically involved in bone remodeling processes. A commercialized recombinant hBMP2 produced in mammalian cell lines is available in different clinical applications where bone regeneration is needed, but widespread use has been hindered due to an unfavorable cost/effective ratio. Protein bodies are very large insoluble protein polymers that originate within the endoplasmic reticulum by prolamine accumulation during the cereal seed development. The N-terminal domain of the maize prolamin 27 kD γ-zein is able to promote protein body biogenesis when fused to other proteins. To produce high yield of recombinant hBMP2 active domain (ad) in stably transformed tobacco plants we have fused it to the γ-zein domain. We show that this zein-hBMP2ad fusion is retained in the endoplasmic reticulum without forming insoluble protein bodies. The accumulation levels are above 1% of total soluble leaf proteins, indicating that it could be a rapid and suitable strategy to produce hBMP2ad at affordable costs
Employee engagement and disengagement: The role of employee voice approaches, organizational justice climate, and HRM
No full textPurpose – Engaged communication behaviour of employees generates positive outcomes such as brand building. On the other hand, disengaged communication behaviour of employees, such as not speaking out suggestions to managers, is quite spread. The purpose of this study is to understand why employees engage (or do not) in communication behaviour devoted to positively affect their company.
Method – A biannual study including: literature review; 10 interviews with consultants; survey with about 100 internal communication managers of large companies; survey with about 300 employees.
Findings – The antecedents of employee communication behaviour are organizational policies, managerial practices, organizational justice procedures, and HR management adopted by companies.
Practical implications – Companies should adopt proper approaches to sustain engaged communication behaviour of their employees and prevent the disengaged one
Transcatheter Repair of Severe Functional Tricuspid Insufficiency Using a Mitral Clip System: Transgastric Views Are the Key for an Effective Guide
No full textMild Regiospecific Synthesis of 1-Alkoxy-isochromenes Catalysed by Well-Defined [Silver(I)(Pc-L)] Complexes
No full textThe synthesis of 3-substituted-1-alkoxyisochromenes starting from 2-alkynylbenzaldehydes and different alcohols is reported. The reaction is catalysed by a silver(I)complex with an original macrocyclic pyridine-containing ligand (Pc-L). The approach is characterised by absolute regioselectivity, mild reaction conditions, good to excellent reaction yields, cleanness of the reaction and reduced purification steps. The reaction mechanism is investigated by in-depth 1H NMR experiments and an aimed “trapping” experiment
