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
Parametric grammar. The shape of Villa Giulia, between cognitive coherence and data enrichment
Full text linkThe research theme is the identification of a prototype procedure for the construction of parametric models useful for the communication of Cultural Heritage. The final result of the experimentation, applied to architectures marked by the presence of classical architectural orders and sculptural apparatus, has generated communicative artifacts. Reconstructing a conoscitive model of a real space has meant composing a navigation interface through which to convey and illustrate architecture with other potentialities, responding at the same time to specific characteristics of perceptive and geometric quality for the user
The unconventional measures of monetary policy: a model to test the operating effectiveness
No full textIn early 2010, the weakness of public finances in some Eurozone countries and the consequent
difficulties for their credit institutions compromised the smooth functioning of the transmission
mechanism of monetary policy. In this context, the European Central Bank intervened
immediately reintroducing a series of unconventional monetary policy measures. These measures
aimed at countering the malfunction of the inter-bank markets and, consequently, ensuring that
the effective transmission of monetary impulses were preserved. After a brief summary of the
main unconventional measures implemented by the ECB between 2010 and 2012, this study
intends to verify if these measures actually contributed to the achievement of those objectives.
To this end, an empirical test was developed based on the consideration that the interbank money
market conditions of efficiency can be summarized in the dynamics of the Euribor-OIS spread.
The latter can be considered a kind of parameter measuring the efficiency of the money market.
In other words, an upward trend of that spread can be interpreted as a clear sign of tension, or
inefficiency. Conversely the opposite is true. The analysis developed shows that the increase of
Euribor-OIS 3m spread was affected by deterioration in the liquidity of the banks. This was
mitigated by the non-conventional measures, but especially by growing concerns about their
financial soundness. This circumstance therefore limited the effectiveness of the ECB measures,
which could help to mitigate the problems related to the lack of liquidity in the interbank market,
but were not suited to solving the underlying problems of the solvency of the banks
Unravelling HP1 functions: post-transcriptional regulation of stem cell fate
Full text linkHeterochromatin protein 1 (HP1) is a non-histone chromosomal protein first identified in Drosophila as a major component of constitutive heterochromatin, required for stable epigenetic gene silencing in many species including humans. Over the years, several studies have highlighted additional roles of HP1 in different cellular processes including telomere maintenance, DNA replication and repair, chromosome segregation and, surprisingly, positive regulation of gene expression. In this review, we briefly summarize past research and recent results supporting the unexpected and emerging role of HP1 in activating gene expression. In particular, we discuss the role of HP1 in post-transcriptional regulation of mRNA processing because it has proved decisive in the control of germline stem cells homeostasis in Drosophila and has certainly added a new dimension to our understanding on HP1 targeting and functions in epigenetic regulation of stem cell behaviour
