Banks’ attitude to partnership as an antecedent of Open Banking platforms: structural determinants and effects on performance in the Italian context
The recent developments in regulation, in particular PSD2 and ICT technologies, are fostering the Open Banking phenomenon, a model of forced or voluntary collaboration based on the sharing of data and applications between subjects not necessarily affiliated, in order to develop, produce and distribute innovative and value-added financial products and services for the customer. Open Banking is still in its early stages, and the approach with which banks decide to interpret and adapt to the new PSD2 regulations is crucial to grasp the evolution of the structure and operativity of the financial system in the coming years, as well as the role that banks will play in it. Indeed, a positive banks’ attitude to partnership is a crucial factor for developing Open Banking ecosystems and platforms and deserves the attention of researchers.
In this paper, we investigate the attitude to partnership of a sample of 45 Italian banks, which allows us to better understand whether there exist conditions for creating Open Banking ecosystems. Furthermore, we explore the economic determinants of banks’ attitudes to partnership and its effect on performance. Results reveal a low current attitude to partnership of Italian banks, a factor that may hinder the formation of Open Banking ecosystems and platforms. The attitude to partnership tends to be low for larger and more capitalised banks, while the opposite occurs for smaller and less capitalised banks, which can be more inclined to participate in Open Banking platforms to compensate for possible constraints in size, resources and human capital. Overall, participation in Open Banking platforms can be justified by the positive effect of attitude to partnership on banks’ performance, as shown by our analysis
Il finanziamento della ricerca clinica in Advanced Therapy Medicinal Products (ATMP): cosa determina l'intervento della Finanza?
Il finanziamento della ricerca medica è un prerequisito per migliorare la salute pubblica e l'inclusione sociale ed economica. Tuttavia, la ricerca medica incontra numerosi ostacoli nell’ottenimento di finanziamenti, che sono ancora più rilevanti per la ricerca su Advanced Therapy Medicinal Products (ATMP). Lo sviluppo clinico
degli ATMP presenta sfide peculiari che possono influenzare il processo di valutazione degli investitori e le
decisioni di investimento, con conseguente errata o mancata allocazione delle risorse finanziarie da parte di investitori pubblici e privati. L'industria finanziaria ha il potenziale per mobilitare capitali pazienti e superare le difficoltĂ di finanziamento della ricerca nel campo degli ATMP.
Combinando un approccio sia qualitativo che quantitativo, questo studio indaga se e come le istituzioni finanziarie investono nella ricerca medica sugli ATMP e quali sono i fattori trainanti dell'intervento della finanza attraverso un campione di 1.042 studi clinici europei nell’ambito degli ATMP.
Attualmente, il settore finanziario supporta indirettamente la ricerca clinica in ATMP. Tale supporto si concretizza attraverso il finanziamento di PMI impegnate in studi clinici in ATMP di Fase I, solitamente piĂą
soggette a esclusione o razionamento finanziario. Questo studio, peraltro, dimostra empiricamente che l’investimento in queste PMI è caratterizzato da un processo decisionale razionale. Nello specifico, risultati suggeriscono che le istituzioni finanziarie si concentrano su progetti caratterizzati da minore incertezza, un orizzonte temporale più breve tra investimento e ritorno economico, maggiore fattibilità , maggiore qualità e rigore metodologico e maggiore diversificazione delle malattie target
Am empirical comparison of the performance of classical power indices
Power indices are general measures of the relative voting power of individual members of a voting body. They are useful in helping understand and design voting bodies particularly those which employ weighted voting, in which different members having different numbers of votes. It is well known that in such bodies a member's voting power, in the sense of their capacity to affect the outcomes of votes called, rarely corresponds to the actual number of votes allocated to him. Many voting bodies for which this is an important consideration exist: examples include international organisations (notably the World Bank, the IMF, the European Union), the US presidential Electoral College and corporations in which votes are proportionate to stockholdings.
Two classical power indices dominate the literature: the Shapley-Shubik index and the Banzhaf index (also known by other names). Both are based on the idea that a member's power depends on the relative number of times they can change a coalition from losing to winning by joining it and adding their vote. They may be defined in probabilistic terms as the probability of being able to swing the result of a vote, where all possible outcomes are taken as equiprobable. The indices differ however in the way they count voting coalitions. In probabilistic terms they use different coalition models and therefore differ in precisely what is meant by equiprobable outcomes.
The indices have been used in a number of empirical applications but their relative performance has remained an open question for many years, a factor, which has hindered the wider acceptance of the approach.
Where both the indices have been used for the same case, they have often given different results, sometimes substantially so, and theoretical studies of their properties have not been conclusive. There is therefore a need for comparative testing of their relative performance in practical contexts. Very little work of this type has been done however for a number of reasons: lack of independent indicators of power in actual voting bodies with which to compare them, difficulties in obtaining consistent data on a voting body over time with sufficient variation in the disposition of votes among members of actual legislatures and the lack of independent criteria against which the results of the indices may be judged. It has also been hampered to some extent by lack of easily available algorithms for computing the indices in large games.
This paper assesses the indices against a set of reasonable criteria in terms of shareholder voting power and the control of the corporation in a large cross section of British companies. Each company is a separate voting body and there is much variation in the distribution of voting shares among them. Moreover reasonable criteria exist against which to judge the indices. New algorithms for the Shapley-Shubik and Banzhaf indices are applied to detailed data on beneficial ownership of 444 large UK companies without majority control. Because some of the data is missing, both finite and oceanic games of shareholder voting are studied to overcome this problem.
The results, judged against these criteria, are unfavorable to the Shapley-Shubik index and suggest that the Banzhaf index much better reflects the variations in the power of shareholders between companies as the weights of shareholder blocks vary
Pliocene colonization of the Mediterranean by Great White Shark inferred from fossil records, historical jaws, phylogeographic and divergence time analyses
Aim: Determine the evolutionary origin of the heretofore poorly characterized contemporary Great White Shark (GWS; Carcharodon carcharias) of the Mediterranean Sea, using phylogenetic and dispersal vicariance analyses to trace back its global palaeo-migration pattern. Location: Mediterranean Sea. Taxon: Carcharodon carcharias. Methods: We have built the largest mitochondrial DNA control region (CR) sequence dataset for the Mediterranean GWS from referenced historical jaws spanning the 19th and 20th centuries. Mediterranean and global GWS CR sequences were analysed for genetic diversity, phylogenetic relationships and divergence time. A Bayes factor approach was used to assess two scenarios of GWS lineage divergence and emergence of the Mediterranean GWS line using fossil records and palaeo-geographical events for calibration of the molecular clock. Results: The results confirmed a closer evolutionary relationship between Mediterranean GWS and populations from Australia–New Zealand and the North-eastern Pacific coast rather than populations from South African and North-western Atlantic. The Mediterranean GWS lineage showed the lowest genetic diversity at the global level, indicating its recent evolutionary origin. An evaluation of various divergence scenarios determined the Mediterranean GWS lineage most likely appeared some 3.23 million years ago by way dispersal/vicariance from Australian/Pacific palaeo-populations. Main conclusion: Based on the fossil records, phylogeographic patterns and divergence time, we revealed that the Mediterranean GWS population originated in the Pliocene following the Messinian Salinity Crisis. Colonization of the Mediterranean by GWS likely occurred via an eastward palaeo-migration of Australian/eastern Pacific elements through the Central American Seaway, before the complete closure of the Isthmus of Panama. This Pliocene origin scenario contrasts with a previously proposed scenario in which Australian GWS colonized the Mediterranean via antipodean northward migration resulting from navigational errors from South Africa during Quaternary climatic oscillations
Rare-earth solid-state qubits
Quantum bits (qubits) are the basic building blocks of any quantum computer.
Superconducting qubits have been created with a 'top-down' approach that
integrates superconducting devices into macroscopic electrical circuits [1-3],
whereas electron-spin qubits have been demonstrated in quantum dots [4-6]. The
phase coherence time (Tau2) and the single qubit figure of merit (QM) of
superconducting and electron-spin qubits are similar -- Tau2 ~ microseconds and
QM ~10-1000 below 100mK -- and it should be possible to scale-up these systems,
which is essential for the development of any useful quantum computer.
Bottom-up approaches based on dilute ensembles of spins have achieved much
larger values of tau2 (up to tens of ms) [7, 8], but these systems cannot be
scaled up, although some proposals for qubits based on 2D nanostructures should
be scalable [9-11]. Here we report that a new family of spin qubits based on
rare-earth ions demonstrates values of Tau2 (~ 50microseconds) and QM (~1400)
at 2.5 K, which suggests that rare-earth qubits may, in principle, be suitable
for scalable quantum information processing at 4He temperatures
Occurence of two NOS isoforms in the developing gut of sea bass Dicentrarchus labrax (L.)
In this work we have examined the appearance and distribution of nitric oxide synthase (NOS), with histochemical, immunohistochemical and biochemical methods, during development of the sea bass (Dicentrarchus labrax) gut. The data showed that both the calcium-calmodulin dependent neuronal isoform (nNOS) and calcium-independent inducible isoform (iNOS) are present in the larval gut of sea bass. The nNOS-immunoreactivity was present in the epithelial cells and enteric nerve cells of gut both in the 8-day-old specimens and in the 24-day-old-larvae. In the adult nNOS-immunoreactivity disappeared from epithelial cells, remaining in the wall intramural neurons and fibers. The iNOS-immunoreactivity was present in the epithelial cells of 24-day-old-larvae and was not detectable in the adult gut. Western blot analysis and determination of NOS activity also demonstrated the presence of the two NOS isoforms, nNOS and iNOS, in the gut of 24-day-old specimens. The presumably different roles played by the two isoforms of enzyme are discussed. The presence of nNOS isoform in the gut enteric neurons of the same larval stages of D. labrax in which we previously demonstrated the presence of substance P and Vasoactive Intestinal Polypeptide (VIP), may suggest that all these three components of the motility control system are already present in the larval phase. Nitric oxide (NO) may be also involved in the early immune response. The present results on the occurrence of iNOS isoform in epithelial gut cells of the same regions in which the gut-associated lymphoid tissue (GALT) will differentiate, may suggest for NO a role in early defence mechanisms, before the establishment of immune responses in GALT. Finally, the developmental and regional differences in nNOS and iNOS expression also suggest a regulatory role in development and differentiation of the sea bass gut.In this work we have examined the appearance and distribution of nitric oxide synthase (NOS), with histochemical, immunohistochemical and biochemical methods, during development of the sea bass (Dicentrarchus labrax) gut.
