Hadronic decays of the tau lepton into K K pion modes within Resonance Chiral Theory

Tau decays into hadrons have a twofold interest: On the one hand, they are a clean environment for studying the hadronization of the left-handed current of QCD, while, on the other side, provide relevant dynamical information of the resonances that mediate these processes. Within an effective field theory-like framework, namely Resonance Chiral Theory, we analyse the decays ot the tau into K K pion modes and compare the results with CLEO and BaBar data. In this way, we provide bounds on the couplings entering our Lagrangian and predict the corresponding spectral functions. As a main result -and contrary to the bulk of theoretical studies and experimental analyses- we find vector current dominance on these decays.Comment: 7 pages, 1 figure, Prepared for the conference QCD@Work07 in Martina Franca, Bari, Italy.

Mobile learning for the integration of groups that risk being marginalized

Social inclusion and cohesion are two of the objectives that the European Union has very often proclaimed in its documents, in the past ten years. At the same time, community policies have emphasized the role that ICTs can play to encourage and support participation and integration opportunities of disadvantaged citizens. Within this context, the ENSEMBLE project, presented here, aims at developing a strategy of use of ICTs to promote socio-cultural integration of immigrant citizens by using technologies such as MP3 players and mobile phones, and by experimenting instructional methods and communication models suitable for the adopted instruments. The present paper focuses particularly on the educational communication design of MMS messages

Barriers to reusing and recycling office fit-out: An exploratory analysis of demolition processes and product features

© 2020 by the author(s). Within the highly waste-generative context of Australia, waste from demolition of office fit-out significantly contributes to unsustainable landfilling. The extant literature is, however, slim on scrutiny of the situation. Therefore, this study aims to uncover office fit-out demolition processes and product features that drive high ratio of landfilling fit-out elements. The research used ten case projects and fourteen interviews to document visible and latent parameters of office fit-out waste. Waste-stream mapping and decision-tree techniques, in conjunction with basic descriptive statistics, were used to model and visualize the extent and drivers of unsustainable fit-out demolition. Further, an exemplar product features analysis was conducted to validate the identified drivers. The findings show that 78% of fit-out waste from the studied cases is landfilled. This high rate is attributed to both latent and visible factors. The main latent factor is high lease price of premium or high-quality offices which favours expeditious demolition with low consideration for reuse and recycling. Key technically visible barriers are volumetric furniture, heterogeneous fit-out assemblies, and insufficient critical mass. To move away from landfilling, production of office fit-out should be transformed for sustainable material adequacy, product re-configurability and de-constructability, and easy handling in the use phase

Intelligenza e coscienza : l\u2019I.A. tra Searle e Dennet : sviluppi dell\u2019intelligenza artificiale

Questo lavoro \ue8 incentrato sull\u2019Intelligenza Artificiale e sul complesso dibattito che esiste in merito alle possibilit\ue0 di creare una \u201cmacchina che pensa\u201d al pari dell\u2019uomo. Da questa analisi, emerge che le chance di successo del programma dell\u2019IA variano al variare delle teorie della mente che sono state affrontate negli ultimi anni. In questo senso, molto dipende dal significato che viene conferito ad alcuni degli elementi propriamente mentali, quali la coscienza e l\u2019intenzionalit\ue0: chi sostiene siano riducibili a stati fisici \ue8 in genere concorde con gli scopi dell\u2019IA e ottimista sui risultati. Chi, al contrario, pensa che tali elementi non siano riducibili a stati fisici, \ue8 scettico nei confronti dell\u2019IA e degli esiti possibili. Nell\u2019ultima parte del lavoro, si affrontano alcuni dei temi pi\uf9 caratteristici dell\u2019IA, a partire dai primi programmi per arrivare alle reti neurali e agli algoritmi genetici; nonostante i successi conseguiti nel settore, sembra che si sia ancora lontani dal riprodurre la mente umana nella sua interezza. Per tale motivo, alcuni studiosi, di recente, hanno sottolineato la necessit\ue0 di affiancare all\u2019I.A. un\u2019altra disciplina: la C.A., \u201cCoscienza Artificiale\u201d
