    In the recent years, analysing a computer or a digital device has become a necessity in the field of criminal investigations. However, during the forensic analysis some ordinary mistakes are often made. This paper aims at defining a new approach to the problem of evidence examination, studying the practical experience of a case study within the Italian legal system concerning techniques of forensic computer analysis based on command line. The user of this type of approaches has to guarantee efficient level of both technical skills and highly qualified and specialized legal competences in order to analyse digital systems in conformity with international best practices, and national and European regulations. Moreover, although many specific hardware and software are adopted in the forensic tests, one of the main objectives of this research has been the only use of the personal computer in order to prove the possibility to obtain the same results minimizing the costs. The case study has focused on forensic analysis of various magnetic and optical devices (mass memory), such as hard disk, pen drives, cards and CD / DVD

    Over the last few years, analysing a computer or a digital device has become a necessity in the field of criminal investigations. However, during the forensic analysis, some ordinary mistakes are often made. The aim of this paper is to define a new approach to the problem of evidence examination, analysing and studying practical experiences of case studies within the Italian legal system concerning techniques of computer forensic and forensic data analysis. The user of this type of approaches has to guarantee efficient level of both specialized legal competences and technical skills and highly qualified technical skill in order to analyse digital systems in conformity with the best practices, and national and European regulations. In addition, although many types of software are not free and particular hardware could be adopted in this presented work, one of the main objectives has been the only use of the personal computer in order to prove the possibility to obtain the same results minimizing the costs. The cases studies have focused on computer forensic of various magnetic and optical devices (mass memory), such as hard disk, usb flash, memory and cards

    Live digital forensics: Windows XP vs Windows 7

    Over the last few years, analysing a computer or a digital device has become a necessity in the field of criminal investigations. Traditional digital forensics analysis includes static analysis, which concerns data that are permanently stored in devices, and live analysis, which regards data that are temporarily stored in equipments or that transit in networks. This paper proposes a live forensics analysis on two different operating systems: Windows XP and Windows Seven. The case study focuses on some common applications such as Skype, Google Talk and the browser Internet Explorer. The last software involves only those cases in which the browser is surfing on Facebook, Yahoo, Hotmail and Gmail. In addition, although many types of applications are payment software, one of the main objectives of this work has been the only use of the free software in order to prove the possibility to obtain the same results minimizing the costs

    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

    In this work we present an overview of NotreDAM, an open source Digital Asset Management platform targeted to the mid-market segment. NotreDAM provides a web-based multi-user application environment for uploading, annotating, cataloguing, sharing, searching and retrieving digital resources such as videos, audios, images and documents. NotreDAM main advantages are: XMP metadata support, user-defined workspaces and catalogs, scalable processing of resources, a scripting engine extendible through plugins and a REST API for integration with third party applications. The demo will showcase the capabilities of the platform through a typical user session

    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

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
