No full text‘Get back to where you once belonged’? Effects of skilled internal migration on Italian regional green growth
No full textThe paper investigates the effects of internal migration on green growth in Italian regions. We use employment in “sustainable” sectors to measure green growth, resorting to a novel measure based on the EU taxonomy for sustainable activities. Using data from 103 Italian regions (NUTS3) from 2008 to 2018, we find that highly skilled interregional migrants are positively related to green employment in their destinations. The effect is possibly due to return migrants to the Southern regions. Overall, the evidence emphasizes the importance of human capital migration in sustainable development
The learning mechanisms through public procurement for innovation : the case of government-funded basic research organizations
Full text linkWe investigate how the procurement activity of government-funded science organizations support the performance of the firms involved in their supply chain. Specifically, the aim of the paper is to identify the mechanisms and disentangle the channels driving this process.
Our testing ground is the Italian Institute for Nuclear Physics (INFN). We frame our study as a mixed-methods research project: three distinct but complementary methodologies are employed, which combine quantitative and qualitative evidence. Firstly, econometric and Bayesian Network analyses are performed, using the information collected through an online survey to suppliers as well as balance-sheet data extracted from online databases. Then, five case-studies are investigated in-depth, carrying out direct interviews with company staff.
Our findings suggest that four types of benefits stem from suppliers’ cooperation with INFN: learning, innovation, market penetration, and networking. These gains represent “intermediate outputs” which in turn impact on suppliers’ socio-economic performance. We provide evidence that suppliers involved in innovative procurement usually experience the greatest benefits. This is mainly explained by the new technical competencies acquired, which are exploited to develop new products that support company business development and sales. On the contrary, reputational gains, leading to the acquisition of new clients, are experienced also by companies involved in regular procurement
Development of an enzyme mimic using self-selection
No full textThe development of a serine protease model using a self-selection protocol is described. The developed system mimics the regeneration step of an enzyme involved in covalent enzyme catalysis. A transition-state analogue of a transesterification reaction is used to self-select functional groups able to accelerate ester cleavage. It is shown that the insertion of a tertiary amine substituent flanking the reaction center reinforces transition-state stabilization by directing the reactive center towards the self-selected functionality. In addition, the tertiary amine activates a bland (solvent) nucleophile for attack on an ester bond similar to what occurs in a serine protease. A quantitative correspondence is observed between the amplification factors and catalytic activity, illustrating the potential of the dynamic covalent capture strategy to precisely detect and quantify weak noncovalent interactions. © 2013 Wiley-VCH Verlag GmbH & Co.

No full textInternal quality assurance in universities: does NPM matter?
No full textFollowing the ideas of New Public Management, Quality Assurance (QA) practices have become a relevant concern for public organizations. In the Higher Education sector, QA policies have inspired different reforms, becoming a debated issue for universitiesâ leaders and policy-makers. This article analyzes the implementation of a newly defined committee for quality assurance (QAC) within Italian universities in order to identify if, as happened in other NPM reforms, it represents a further example of âimplementation gapâ; and to detect the key variables that promote a satisfactory QAC functioning. Based on both the analysis of the composition and the role of QAC in all the Italian public universities and significant case studies, we have identified some core variables that promote the implementation of an effective QAC and ultimately supports the overall QA policy

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
