Teoria e tecnica delle comunicazioni di massa

In recent years, the interest in communication studies, also stimulated by requests from the labour market, has grown enormously and has given rise to a lively debate in which many disciplines take part, with often contradictory positions. This situation makes it difficult to discuss all the aspects related to communication in a coherent and universally accepted perspective. This work, however, is an attempt in this sense and, starting from a historical (as complete as possible) reconnaissance, aims at offering a series of working hypotheses recognisable as unifying. The first part of the volume therefore examines the main communication models and presents the positions that, based on the notion of communicative competence, seem more valid. The second part illustrates the applications of some communication models in advertising communication and in the communication of the fashion system, thus also helping to provide solutions to practical management problems

Web 2.0, Language Learning and Intercultural Competence

Whenever a new form of communication appears on the scene, it immediately becomes the object of discussion. This has been going on since the first penny press edition in 1834, whereas today discussions are carried out with reference to the Internet. The stability with which mass-media have faced different criticism can be well understood thanks to the functionalist analysis which considers the media as a social system working within an external system made up of a set of cultural and social conditions. In spite of its complexity, any set of repetitive actions contribute to maintaining or to weakening the stability of the system. We can say that globalization would not have been possible without the media and Web 2.0 may be of remarkable interest for its role in influencing cultural identity. All the past technologies, from electric light to the airplane, took a whole generation to gain ground among people, and Internet has not required such a long time. The impossibility to digest the new modalities of communication offered by the net creates the risk of unexpected contamination. Geographical magazines often show pictures of native Amazonians dressed in their traditional costumes while using computers and mobile phones. Educational uses of Web 2.0 and mobile learning tools have been rapidly expanded over the last few years and a great number of projects have been planned for teaching languages. Mobile learning includes many areas: handheld computers, MP3 players, notebooks and mobile phones. In this paper we shall outline the methodology including selection of web tools, task design, implementation and intercultural communication. The study carried out at the University of Florence shows that learners develop their communication competence while performing entertaining activities which enable them to achieve the desired goals

Difficult abdominal access in laparoscopic cholecystectomy in elderly patients: our experience and literature review.

AbstractLaparoscopic cholecystectomy (LC) is currently the gold standard treatment for symptomatic cholelithiasis. LC is actually condidered a medium complexity surgical operation. LC could be technically hard, especially if patient underwent previous surgical operation. These difficulties increase in outcome of previous operation in right upper quadrant (RUQ): in this case laparoscopic access is defined as an “hard access”. We present two cases in which an unconventional access was performed: laparoscopic cholecistectomy is a safe and feasible procedure, although a careful assessment preoperative is indispensable. In particular, caution is required in both the triangulation of the trocar, which in pneumoperitoneum induction

Syngas quality in fluidized bed gasification of biomass: comparison between olivine and K-feldspar as bed materials

The relevance of selecting an appropriate bed material in fluidized bed gasification is a crucial aspect that is often underestimated. The ideal material should be economical, resistant to high temperatures and have small chemical interaction with biomass. However, often only the first of such three aspects is considered, neglecting the biomass–bed interaction effects that develop at high temperatures. In this work, olivine and K-feldspar were upscale-tested in a prototype fluidized bed gasifier (FBG) using arboreal biomass (almond shells). The produced syngas in the two different tests was characterized and compared in terms of composition (H2, CH4, CO, CO2, O2) and fate of contaminants such as volatile organic compounds (VOCs), tar and metals.. Moreover, the composition of olivine and K-feldspar before and after the biomass gasification process has been characterized. The aim of this work is to show which advantages and disadvantages there are in choosing the most suitable material and to optimize the biomass gasification process by reducing the undesirable effects, such as heavy metal production, bed agglomeration and tar production, which are harmful when syngas is used in internal combustion engines (ICE). It has been observed that metals, such as Ni, Cu, Zn, Cd, Sn, Ba and Pb, have higher concentrations in the syngas produced by using olivine as bed material rather than K-feldspar. In particular, heavy metals, such as Pb, Cu, Cd, Ni and Zn, show concentrations of 61.06 mg/Nm3, 15.29 mg/Nm3, 17.97 mg/Nm3, 37.29 mg/Nm3 and 116.39 mg/Nm3, respectively, compared to 23.26 mg/Nm3, 11.82 mg/Nm3, 2.76 mg/Nm3, 24.46 mg/Nm3 and 53.07 mg/Nm3 detected with K-feldspar. Moreover, a more hydrogen-rich syngas when using K-feldspar was produced (46% compared to 39% with olivine)

Lingue e lavoro tra comunicazione e glottodidattica

The essay claims that International economy and trade were among the relevant factors which caused - since classical times - the shift from intuitive language teaching methodologies to  more rigorous and scientifically-based approaches. Some examples concerning the language of some jobs and professions are provided
