Environmental forensics: Where techniques and technologies enforce Safety and security programs
No full textSafety and security engineering involve several and complex multidisciplinary activities aimed to preserve people and the environment from hazards and risks. These concepts that were born as "umbrella" terms for the laws, rules; process design is generally applied only for workplaces or related to the employees; indeed, the scenario of related applications is only limited by the typical needs of the specific context. Recently, new methods and applications for detecting, evaluating, and tracking signs of environmental contamination are validating the effectiveness of safety and security engineering tools also in the environmental field. As in a workplace an engineer is called to analyze a complex scenario (e.g. to evaluate a risk, to assess a real danger and, therefore, look for causes to define the dynamics and find a solution), in the same way the environmental forensic scientist has to examine scenarios and actors to define the relationships to reveal source, path and target; in both the same techniques and technologies used in the analyses play a key role. This paper introduces a multidisciplinary strategy that bridges different approaches incorporating remote/proximal sensing applications where techniques and technologies enforce safety and security programs. A part of Campania coast, close to Salerno city in southwestern Italy, was chosen as a test bed of our strategy. All the activities were performed supporting the environmental investigations directed by Salerno Prosecutor Office and also cooperating with Italian police and several Government bodies. This paper provides an example where law enforcement and university research teams collaborate to develop enhanced environmental protection methods

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
