A computational platform for the virtual unfolding of Herculaneum Papyri.

Ancient Herculaneum papyrus scrolls, hopelessly charred in the 79 A.D. Vesuvius eruption, contain valuable writings of the Greek philosophers of the day, including works of the Epicurean Philodemus. X-ray phase contrast tomography has recently begun unlocking their secrets. However, only small portions of the text hidden inside the scroll have been recover. One of the challenging tasks in Herculaneum papyri investigation is their virtual unfolding because of their highly complicated structure and three-dimensional arrangement. Although this procedure is feasible, problems in segmentation and flattening hinder the unrolling of a large portion of papyrus. We propose a computational platform for the virtual unfolding procedure, and we show the results of its application on two Herculaneum papyrus fragments. This work paves the way to a comprehensive survey and to further interpretation of larger portions of text hidden inside the carbonized Herculaneum papyri.

[Training means to get skills: a comparison between D.Lgs. 81/08 and B-BS]. / Formazione significa acquisire competenze: un raffronto tra il D.Lgs. 81/08 e la B-BS.

The 81/08 Decree gives a strategic role to the processes that provide information, knowledge and training, regarded as fundamental measures to improve health and safety conditions in the workplace. The most important aim of health and safety training is to acquire skills to carry on duties according to safety principles in the company. Competence consists of the possession and application of integrated knowledge, skills and behaviors. To achieve these results, it is essential the desire of the organization, at all levels, to invest on learning and development, highlighting the benefits arising from the adoption of safe behavior by workers. Different methodologies contribute to this aim, including those developed within the behavioral sciences, such as the Behavior-Based Safety (B-BS), which is based on the development of safe behaviors, through the implementation of a registration system for behavior, feedback and positive consequences. This report will make a comparison between the elements that characterize health and safety training provided by the D. Lgs. 81/08 and the enforcement of protocols for B-BS in companies.
