Identidad, escritura, performance: Marco Paolini, actor y autor

Marco Paolini es uno de los más representativos actores y autores del llamado "teatro di narrazione". El presente artículo pretende acercarse a algunos aspectos centrales de su poética en tanto actor y escritor, tales como los complejos y articulados procesos a través de los cuales llega a un (más o menos) definitivo texto escrito; la fuerte relación que establece entre él y su público, a quien Paolini siempre se dirige consciente y explícitamente con gags y "bromas" en ocasiones tomados de la tradición del teatro popular italiano; o el "lenguaje del cuerpo" que Paolini pone en práctica en el escenario y en las páginas de sus libros publicados, en el que (de un modo personal) mezcla el italiano, dialectos venecianos y ecos de poetas y escritores de la tradición literaria italiana

Ultracold atoms trapped in optical lattice

In this Thesis we study a paradigmatic experimental set up established for the study of quantum many-body system, namely ultracold atoms trapped in optical lattice. In particular, we consider interacting bosons placed into a periodic optical lattice generated by a set of counter-propagating laser beams that form a stationary electric potential. The work will be organized as follows: first, we consider the system Hamiltonian in the formalism of first quantization. We introduce the second quantization formalism in order to derive the Bose-Hubbard Hamiltonian and study the proprieties of the system by doing a numerical analysis. Also, in this case we numerically study this system in order to gather informations about its proprieties.ope

A review of the book curated by Renee Hobbs: "Exploring the Roots of Digital and Media Literacy through Personal Narrative". The book mainly aims to provide readers with a picture of the main concepts and of the most influential theories and practices that structured Digital and Media Literacy as disciplines; and it does that by creating a sort of dialogue between the past and present

How mucosal epithelia deal with stress: Role of NKG2D/NKG2D ligands during inflammation

Mucosal epithelia encounter both physicochemical and biological stress during their life and have evolved several mechanisms to deal with them, including regulation of immune cell functions. Stressed and damaged cells need to be cleared to control local inflammation and trigger tissue healing. Engagement of the activating NKG2D receptor is one of the most direct mechanisms involved in the recognition of stressed cells by the immune system. Indeed, injured cells promptly express NKG2D ligands that in turn mediate the activation of lymphocytes of both innate and adaptive arms of the immune system. This review focuses on different conditions that are able to modulate NKG2D ligand expression on the epithelia. Special attention is given to the mechanisms of immunosurveillance mediated by natural killer cells, which are finely tuned by NKG2D. Different types of stress, including viral and bacterial infections, chronic inflammation, and cigarette smoke exposure, are discussed as paradigmatic conditions for NKG2D ligand modulation, and the implications for tissue homeostasis are discussed

Natural killer cell response to chemotherapy-stressed cancer cells: Role in tumor immunosurveillance.

Natural killer (NK) cells are innate cytotoxic lymphoid cells that actively prevent neoplastic development, growth, and metastatic dissemination in a process called cancer immunosurveillance. An equilibrium between immune control and tumor growth is maintained as long as cancer cells evade immunosurveillance. Therapies designed to kill cancer cells and to simultaneously sustain host antitumor immunity are an appealing strategy to control tumor growth. Several chemotherapeutic agents, depending on which drugs and doses are used, give rise to DNA damage and cancer cell death by means of apoptosis, immunogenic cell death, or other forms of non-apoptotic death (i.e., mitotic catastrophe, senescence, and autophagy). However, it is becoming increasingly clear that they can trigger additional stress responses. Indeed, relevant immunostimulating effects of different therapeutic programs include also the activation of pathways able to promote their recognition by immune effector cells. Among stress-inducible immunostimulating proteins, changes in the expression levels of NK cell-activating and inhibitory ligands, as well as of death receptors on tumor cells, play a critical role in their detection and elimination by innate immune effectors, including NK cells. Here, we will review recent advances in chemotherapy-mediated cellular stress pathways able to stimulate NK cell effector functions. In particular, we will address how these cytotoxic lymphocytes sense and respond to different types of drug-induced stresses contributing to anticancer activity

Il contributo vuole descrivere quest\u2019esperienza, spiegandone i concetti pedagogici e le connessioni fra le consegne richieste e il framework europeo di competenze digitali DIGCOMP 2.0. In secondo luogo, attraverso un sondaggio online di autovalutazione, gli autori hanno indagato come gli studenti hanno percepito lo sviluppo di tali competenze in relazione ai compiti richiesti dal programma.Since 2014-15, in the Department of Education of the University of Bologna, more precisely within the framework of the bachelor degree curriculum named \uabExpert in Social and Cultural Education\ubb and \uabEducator in Childhood Social Services\ubb, a new programme for the short course called \uabInformation and technology for Education\ubb started to be proposed to the students. This paper explains the rationale behind the programme and its connections with the European Digital Competences Framework DIGCOMP 2.0. Secondly, through an online self-evaluation survey, the authors investigated how students perceived the development of these competences by implementing the steps of the course

Effective metropolitan governance is not an outcome just from a law making process. The Italian case

The Delrio law has been ruling in Italy since the beginning of 2015, and it defines the boundaries of the ex Italian provinces, as metropolitan perimeters. Consequently, numerous problems have arisen from the resulting spatial configuration, both in terms of governance and metropolitan visioning, since only in very few cities the newly established metropolitan boundaries are coherent with urban systems’ dynamics and changes. The analysis of the Italian case helps to demonstrate that effective metropolitan governance does not stem only from a Government-driven and top down provision, and confirms that metropolitan development and governance require the development and strengthening of no-statutory and voluntary approaches, with a strong involvement of the business community. In order to illustrate and critically evaluate the recent Italian experience, this paper presents the results of a comparative analysis of a range of European polycentric metropolitan and industrial areas: Amsterdam (NL), Rotterdam-Den Haag (NL), Lille (FR), Barcelona (ES), Ruhrgebeit (DE). After a dramatic crisis caused by deindustrialisation and economic restructuring, they are all focusing on innovation, the establishment of new high-quality local services, and greater orientation to international competitiveness. These strategies do not stem directly from Government-driven regulation for local authorities, but are, to a large extent, dependent upon cooperative and nostatutory efforts. Moreover, the spatial scales of these initiatives are not always coincident with previous administrative boundaries. As a result, both in case of institutionalized metropolitan authorities as formal level of government, and in case of the absence of formal metropolitan institutions, this paper demonstrates that territorial cooperation is the essential basis for any metropolitan process, that often imply associations of municipalities and other local actors, sharing a common vision, and implementing strategic development projects

R-Symmetry and the Topological Twist of N=2 Effective Supergravities of Heterotic Strings

We discuss R-symmetries in locally supersymmetric N=2 gauge theories coupled to hypermultiplets which can be thought of as effective theories of heterotic superstring models. In this type of supergravities a suitable R-symmetry exists and can be used to topologically twist the theory: the vector multiplet containing the dilaton-axion field has different R-charge assignments with respect to the other vector multiplets. Correspondingly a system of coupled instanton equations emerges, mixing gravitational and Yang--Mills instantons with triholomorphic hyperinstantons and axion-instantons. For the tree-level classical special manifolds $ST(n)=SU(1,1)/U(1)\times SO(2,n)/(SO(2)$ $\times SO(n))$ R-symmetry with the specified properties is a continuous symmetry, but for the quantum corrected manifolds ${\hat {ST}}(n)$ a discrete R--group of electric--magnetic duality rotations is sufficient and we argue that it exists.Comment: 40 pages, plain LaTeX.
