Energy Management Maturity Model: An organizational tool to foster the continuous reduction of energy consumption in companies
No full textEnergy has recently become one of the key aspects that companies should improve and keep monitoring, due to the related economic costs and the significant environmental impacts, to which today’s society is paying more and more attention. An Energy Management System could offer many advantages, such as energy consumption and cost reductions, improvement of corporate image, environmental impact reduction. Organizations have therefore developed more comprehensive approaches to Energy Management, aiming at reducing energy waste, but also at managing energy use by applying specific focused programs. Maturity Models are tools used to assess the level of maturity of an organization, providing a systematic framework for carrying out benchmarking and performance improvement. With regards to Energy Management, existing tools are still not well-structured and do not allow a deep analysis of the level of maturity of an organization and of how this maturity develops along with its dimensions. In this article the described general Maturity Model tools are implemented, providing an innovative method in order to apply those concepts to the Energy Management field, aiming at bridging the aforementioned gaps. A user-friendly tool, focused on the company and its organization, is provided to allow practitioners to easily and autonomously assess their company’s maturity level, drawing a first growth plan draft. This method represents a new way to lead the organization to a proper management of its energy needs, and is alternative or complementary to the certification of the Energy Management System of the organization, being consistent with the ISO 50001 standard
Markers morfologici della degenerazione senile e varicosa della parete safenica [Morphologic markers of elderly and varicous degeneration of safenous wall]
No full textInfluence of the Alps on two troughs affecting WRF forecasts of convection in the Po Valley during HyMeX
No full textTwo Intensive Observation Periods (IOPs) from the HYdrological cycle in Mediterranean Experiment (HyMeX) have been studied here. IOP6 and IOP13 were dedicated to the documentation of heavy precipitation events over target areas in northern Italy. In both cases convection in the Po Valley was also observed, but in each case there was a distinct difference in the ability to reproduce the observations by most of the models available during the campaign. In particular the WRF model was able to reproduce correctly IOP13, whereas it failed in maintaining the squall line moving west to east along the Po Valley during IOP6. A parallel analysis of the two events highlights differences in the dynamics that are critical in determining conditions favorable for convection along the Po Valley. A basic difference is that the trough in IOP6 produced much stronger downslope winds in the lee of the Alpine barrier than it did in IOP13. A comparison with observations from different sources allowed the identification of the models overestimation of the zonal wind in the Po Valley as the main cause of convection suppression during IOP6. Sensitivity tests to the planetary boundary layer (PBL) parameterization show similar results for most of the WRF PBL schemes. However, an improvement in the wind forecast is produced if the Bougeault-Lacarrére scheme is used, thus restoring realistic conditions along the Po Valley that allow for a better simulation of the convective system in IOP6
Towards the 70th Anniversary (1955-2025) of the Joint Libyan-Italian Archaeological Mission in the Tadrart Acacus and Messak (SW Libya).
No full textThe archaeological and scientific cooperation
between Libya and Italy started in the
1920s. A few years after World War ii, Fabrizio Mori
initiated the archaeological mission in the Tadrart
Acacus, a sandstone massif in southwestern Libya,
laying the foundation of one of the longest enterprises
in the North African country. After a short
background of the mission and a concise summary
of the main scientific results, the paper focuses on
the main activities of the Mission – especially the
publications in the Series «aza - Arid Zone Archaeology,
Monographs» – carried out after the beginning
of the Revolution (2011), as well as on the principal
objectives to achieve on the short term. It also
highlights new research avenues that leverage extensive
data from over fifty years of fieldwork in the
Sahara, employing advanced cutting-edge techniques
to investigate socio-cultural and technological
developments. A fundamental action will be directed
toward the removal of the Tadrart Acacus
from the unesco World Heritage sites in danger. In
addition, a special attention is placed on year 2025,
which will represent the 70th anniversary of the
Mission (1955-2025), and the centenary of the birth
of Fabrizio Mori (1925-2025), the founder of the
mission and its director until 1996
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
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
