Innovation, employment and skills in services. Firm and sectoral evidence
No full textIn this article the employment impact of innovation in the heterogeneous universe of services is investigated, using data provided by the 1993–1995 Italian innovation survey (CIS II). The empirical evidence presented shows that the “direct” impact of innovation on employment varies greatly according to the type of innovation strategy pursued by firms, across industries and according to the level of qualification of the labour force. High skilled and qualified jobs do replace low skilled jobs. Among small firms and in less than half of the service sectors considered the net effect is positive, particularly in industries which have a strong scientific and technological base. The negative impact of innovation on employment is on the contrary concentrated among large firms, capital intensive industries and in all financial-related sectors (banking, insurance and other financial services). In the latter industries the labour-saving effect of innovation seems to be linked to the widespread use of Information and Communication Technologies (ICTs) which have contributed to rationalise and increase labour productivity in an important section of services. In the case of Italy, an overall negative impact of innovation on employment has been found. This result is clearly affected by the de-specialisation of the Italian economy in the knowledge intensive services. From an innovation-policy perspective two lines of actions can be envisaged: one enhancing efficiency in the technologically laggard service sectors and a second one aiming at creating the conditions for the emergence and growth of knowledge-intensive branches. The evidence presented suggests that both these lines of policy action are important but also that the second one is likely to be more rewarding in terms of employment growth

The Impact of Innovation on Employment in Services: Evidence from Italy
No full textThis article investigates the employment impact of innovation in services, using the data gathered through the 1993-95 Italian innovation survey. The empirical evidence shows that the impact of innovation on employment varies greatly across industries and according to the level of qualification of the labour force. Among small firms and in less than a half of the service sectors considered, the employment impact of innovation is positive, particularly in industries that have a strong scientific and technological base. A negative impact of innovation on employment is, on the contrary, found among large firms, capital-intensive industries and in all financial-related sectors (banking, insurance and other financial services). In these industries the labour-saving effect of innovation seems to be linked to the widespread use of Information and Communication Technologies (ICTs) which displace the least qualified employees. In the case of Italy, an overall negative impact of innovation on employment is found. It is argued that this result is affected by the Italian economy's specialisation in the most traditional service industries.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Cold storage does not affect ascorbic acid and polyphenolic content of edible flowers of a new hybrid of sage
No full textThe effect of cold storage was studied on flowers and leaves of a new hybrid of Salvia pot-cultivated in Italy (Sanremo, Liguria). In particular, visual appearance, polyphenols, and ascorbic acid (ASA) levels were evaluated upon 6 days (d) of cold storage (5°C). Results showed as flowers and leaves were not affected by enzymatic browning till 6 d storage. ASA content, which was about 4-fold higher in leaves than in flowers, decreased in leaves (-43%) but not in flowers upon storage. Polyphenolic content was not negatively influenced by the storage in both plant tissues. This is one the first report in which the content of nutraceutical compounds was monitored in edible flowers upon storage. Obtained results indicate as flowers of this new Salvia hybrid are suitable to be merchandised in refrigerated sections of retail store in view of their high shelf life associated with high stability of nutraceuticals
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Cyclamen persicum Mill cv. 'Halios': Somatic embryogenesis and phenotypic analysis of somatic embryo-derived plants
No full textCyclamen persicum Mill cv. 'Halios' is a commercial cultivar that is mass produced as pot-plant using F1 hybrid seeds. One of the best and efficient way to propagate in vitro this plant is to induce somatic embryos from callus. Immature ovaries at different stages of development, taken from mother plants, differing for the colour of the petals, were induced to form embryogenic callus into the medium suggested by Schwenkel and Winkelmann (1998). The juvenility of the explants was confirmed to be important for inducing pro-embryogenic masses. It was observed a clonal behaviour in the callus lines obtained: the calli showed different colour and compactness and also a different embryogenic potential. The genotype "white" (line or clone H VII) showed the highest potentiality to produce somatic embryos. The somatic embryos of all the embryogenic genotypes were able to mature, to germinate and to develop into complete plantlets, which were then transferred in vivo. In order to evaluate the homogeneity of the crop, for excluding somaclonal variation events, morphological features as plant height, leaf length, open flower height and petal number were measured. The results show a high homogeneity of the somatic embryo-derived plants that can be considered "true-to-type plants"
