The article gives an insight into criminological problems of bullying in school phenomena. Although the term “bullying” is a modern word, such behaviour has been known for a long time. Bullying is a manifestation of violent behaviour, which threatens the victim's health and safety. The aim of this article is to describe and analyse bullying as a form of expression of violence, showing the criminological aspects of this phenomenon. To achieve the aim of the article the following tasks are defined: to provide the theoretical and practical framework of the research phenomenon, to study and evaluate certain elements of the criminological characterization of the bullying: the description of a victim and a perpetrator, the evaluation of factors and directions of prevention. Theoretical analysis methods such as deconstruction, descriptive and complex analysis, and empirical research methods – document analysis, comparison and compilation were employed in this study.

Two patterns of chip curl, namely up- and side-curl, have been widely recognized in machining operations. This paper presents the third pattern of chip curl that is called lateral-curl. The rotating axis of chip lateral-curl is perpendicular to the rotating axes of up- and side-curl. The essential differences are illustrated between the chip lateral-curl concept and the “chip-twisting” concept presented in other related studies. Based on an analytical vector analysis, a new kinematic characterization is presented for the natural (or born) lateral-curl of the chip that is associated with flat-faced tool machining. It is demonstrated that chip forms (or shapes) can be determined by four governing variables: the chip up-, lateral-, and side-curl radii and the chip side-flow angle. A method to indirectly measure the chip lateral-curl radius is presented. The effect of chip lateral-curl on chip forms is investigated through cutting tests, theoretical analysis, and computer simulations.

Neapolitan still life painting, even though Italy’s most prolific “school” of the genre, has attracted little theoretical analysis. Where scholars have considered the genre almost exclusively in terms of stylistic developments and questions of attribution, this paper, alternatively, draws inspiration from insights formulated largely outside the field of art history: Umberto Eco’s characterization of still life paintings as “visual lists” and Michele Rak’s characterization of seventeenth-century literature in the Neapolitan dialect as “literary still lifes.” Building on these insights, this paper aims to explore the ways in which Neapolitan still life painting was anchored in local literary traditions and how, moreover, these literary traditions help us to understand the way in which these paintings resonate with the specific social and political situation that characterized Spanish Naples.
