Group B Streptococcus prevalence in pregnant women from North-Eastern Italy advantages of a screening strategy based on direct plating plus broth enrichment
To assess the sensitivity of a combined selective broth enrichment technique plus selective plating for the detection of group B streptococcus (GBS) colonisation in a large cohort of pregnant women from North-Eastern Italy 5020 pregnant women were screened between the 35th and the 37th week of gestation during 2002–2005. 901 Women (17.9%) were positive for GBS. On 728 positive samples, corresponding to patients enrolled between 2003 and 2005, the results of selective direct plating and selective broth enrichment were compared. A total of 561 (77.1% of positive samples, corresponding to 13.9% of patients) were positive on direct selective agar; an additional 167 isolates (22.9% of samples, 4.1% of patients) were recovered from the LIM broth subculture. The prevalence of GBS carriage in this study is a reliable estimate considering the sensitivity of the methods used, the rate of attendance of pregnant women to clinical and laboratory settings and the compliance to the protocol

ANALYSIS OF THE EVOLUTION OF ANTHROPOGENIC COASTLINE ADVANCE BETWEEN MONFALCONE AND MUGGIA (NE ADRIATIC SEA) OVER THE LAST 200 YEARS IN A GIS ENVIRONMENT
Coasts are land–ocean interfaces of high environmental and economic value. They are the most affected areas by urban settlements and economic and productive activities, and suffer from increasing anthropogenic pressure. About 10% of the world's population currently lives in coastal areas less than 10 m above sea level, and 40% within 100 km of the coast (UN indicators: http://www.un.org/esa/sustdev/natlinfo/indicators/methodology_sheets). The anthropization process has significantly modified and altered the natural and environmental characteristics of the coastal system, affecting the structure of natural ecosystems, the quality and quantity of natural resources and changing the landscape from natural to anthropic. In Italy, the morphology of the peninsula and its geographical position in the center of the Mediterranean make the coastal areas
an extraordinary resource, both from an environmental, economic and cultural point of view. The Italian coastal area is highly anthropized, with 34% of the Italian population living permanently in coastal cities (ISTAT, 2022). The Italian coastline is about 8,300 km long, 13% of which is made up of artificial structures such as ports, hydraulic and coastal protection structures. In the last 20 years, 5 km of natural coastline has been lost every year due to the construction of new artificial structures (ISPRA, 2020).
The study area is located in the Gulf of Trieste, a shallow semi-enclosed sea of about 500 km2 in the north-eastern Adriatic Sea, in the Italian region of Friuli Venezia Giulia (FVG). The FVG coastline are 111 km long, and the 55.4 % is highly anthropized (Fig. 1) (Zanchini et al, 2017).
In the northern part of the gulf the coasts are characterised by beaches of fine or pebbly sand. In the eastern part, the coast is rocky, with narrow, pebbly and gravelly beaches (Brambati and Catani,1988), constituted by Eocene marls and sandstone of the Trieste formation and Cretaceous and Paleocene limestones. The coastal area near Trieste has been heavily modified by anthropogenic interventions that have altered both the natural coastline and the seabed. The southern part has rock coasts at the foot of abrasion escarpments, with several bays, such as those of Koper and Muggia.
The aim of the study is to evaluate and quantify the evolution and the changes (advances) of the coastline and the consequent loss of the marine (littoral) environment and ecosystem between Monfalcone and Muggia, where the coastline is predominantly rocky, caused by anthropic activities over the last 200 years.
To carry out the analysis, a series of historical charts of the study area from the last 200 years were collected. After georeferencing the charts, the past coastlines were digitized and compared with the current ones using the Geographic Information System (GIS). For example, Fig. 1 shows two of the past digitized coastlines, the one from 1922 and the one from 1927.
The whole evolution of the coastline was analyzed, relating each change to the cause that produced it and the time period in which it occurred. The analysis highlighted that in some areas the advances caused by human activity were even hundreds of meters, mainly due to the construction of infrastructures, ports and industrial settlements. The only retreated section was in the Bay of Muggia (Fig. 1), where the changes were caused by the construction of a navigable canal.
A good understanding of the rates of historical changes is a prerequisite for effective coastal zone management. Only by examining the risks and potential consequences it is possible to find high-quality and innovative solutions to protect the coasts and the social and economic activities based on them

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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

Variations on the Author
“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
