A theoretical analysis of the value added intellectual coefficient (VAIC)
No full textThis paper offers a critical assessment of the value added intellectual coefficient (VAIC) through the analysis of the coherence of the definitions of and semantic relationships among the theoretical constructs at the heart of the model. Some of the criticisms detected here refer to inconsistencies of the VAIC with the most consolidated concepts developed by the Intellectual Capital (IC) literature as well as to the constructs internal to the model and generated by the misalignment of Pulic’s theoretical assumptions with the way they have been translated into the mathematical model. Other criticisms derive from the time mismatch in the relationship among the variables constituting the three ratios and from the ambiguous meanings of human capital efficiency and structural capital efficiency. Implications for both researchers and managers are discussed
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
Paediatric Orthodontics Part 1: Anterior open bite in the mixed dentition
No full textThe correction of anterior open bite in the mixed dentition: treatment or over-treatment? Early treatment of the anterior open bite is a common, widespread treatment, which involves sometimes multiple clinical procedures: active orthodontic treatment and correction of the dysfunctional habits with a large waste of financial and biological costs. Therefore, also considering the significant possibility of self-improvement in the prepubertal phase, active early treatment should not aim to the active correction of the AOB, but only to other aspects of the malocclusion and to the interception of dysfunctional habits
Filter bubble effect in the multistate voter model
No full textSocial media influence online activity by recommending to users content strongly correlated with what they have preferred in the past. In this way, they constrain users within filter bubbles strongly limiting their exposure to new or alternative content. We investigate this type of dynamics by considering a multistate voter model where, with a given probability λ, a user interacts with "personalized information,"suggesting the opinion most frequently held in the past. By means of theoretical arguments and numerical simulations, we show the existence of a nontrivial transition between a region (for small λ) where a consensus is reached and a region (above a threshold λ c) where the system gets polarized and clusters of users with different opinions persist indefinitely. The threshold always vanishes for large system size N, showing that a consensus becomes impossible for a large number of users. This finding opens new questions about the side effects of the widespread use of personalized recommendation algorithms
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
Punibilità del phishing e concorso di reati: ne ter in idem
No full textViene qui esaminata una sentenza del 2019 della Cassazione che, in contrasto con le Sezioni Unite, ha applicato la teoria della consunzione in un caso di criminalità informatica (c.d. phishing). L’autore osserva come la teoria del ne bis in idem sostanziale, sostenuta da una parte autorevole della dottrina, trova oggi elementi di supporto anche nella giurisprudenza europea. Per quanto attiene poi alla recente sentenza della Cassazione, egli condivide la soluzione della sussistenza di un antefatto non punibile, ma osserva che anche il terzo reato realizzato dall’agente avrebbe dovuto essere ricompreso nel giudizio di consunzione: ne ter in idem.The author analyzes, within the framework of the gener- al categories of the formal concurrence of crimes and ap- parent concurrence of rules, the issue of the punishment of phishing and of the solutions prepared in subiecta materia by jurisprudence
