Active Packaging as an Opportunity to Create Package Design that Reflects the Communicational, Functional and Logistical Requirements of Food Products
No full textDesign for services and place development
Full text linkServices are a constituent element of urban planning.
Nevertheless, a new perspective arises when considering
regional contexts, and when considering services
as an approach to design and subject matter for design.
The essay presents reflections raised by a group of
projects in various parts of the world, conducted by local
research partners within the international DESIS
Network (Design for Social Innovation and Sustainability)
and dealing with agricultural periurban territories.
These projects are methodologically related to one currently
in progress in Milan conducted by the Politecnico
di Milano, Slow Food and Università Scienze Gastronomiche,
which is expected to generate a scenario of
sustainable local food production and consumption for
the region
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
Revisiting leptogenesis in a SUSY SU(5)×T′ model of flavour
Full text linkAbstractWe investigate the generation of the baryon asymmetry of the Universe within a SUSY SU(5)×T′ model of flavour, which gives rise to realistic masses and mixing patterns for quarks and leptons. The model employs the see-saw mechanism for generation of the light neutrino masses and the baryon asymmetry is produced via leptogenesis. We perform detailed calculations of both the CP violating lepton asymmetries, originating from the decays of the heavy Majorana neutrinos operative in the see-saw mechanism, and of the efficiency factors which account for the lepton asymmetry wash-out processes in the Early Universe. The latter are calculated by solving numerically the system of Boltzmann equations describing the generation and the evolution of the lepton asymmetries. The baryon asymmetry in the model considered is proportional to the JCP factor, which determines the magnitude of CP violation effects in the oscillations of flavour neutrinos. The leptogenesis scale can be sufficiently low, allowing to avoid the potential gravitino problem
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
A supersymmetric SU(5)×T′ unified model of flavor with large θ13
No full textWe present a SUSY SU(5)×T′ unified flavor model with type I seesaw mechanism of neutrino mass generation, which predicts the reactor neutrino angle to be θ130.14 close to the recent results from the Daya Bay and RENO experiments. The model predicts also values of the solar and atmospheric neutrino mixing angles, which are compatible with the existing data. The T′ breaking leads to tribimaximal mixing in the neutrino sector, which is perturbed by sizeable corrections from the charged lepton sector. The model exhibits geometrical CP violation, where all complex phases have their origin from the complex Clebsch-Gordan coefficients of T ′. The values of the Dirac and Majorana CP violating phases are predicted. For the Dirac phase in the standard parametrization of the neutrino mixing matrix we get a value close to 90°: δ≅π/2-0. 45θc≅84.3°, θc being the Cabibbo angle. The neutrino mass spectrum can be with normal ordering (2 cases) or inverted ordering. In each case the values of the three light neutrino masses are predicted with relatively small uncertainties, which allows one to get also unambiguous predictions for the neutrinoless double beta decay effective Majorana mass. © 2012 American Physical Society
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Convivial aesthetic in social innovation: a nested framework from three projects in Milano
Full text linkSocial structures are increasingly becoming subject matters of design, because considered integral to service design, akin to interfaces, physical elements, and spaces. The paper explores the use of aesthetics to reshape social structures in social innovation. It delves into three social innovation projects in Milan, formulating the concept of 'convivial aesthetic', which refers to the design and creation of materials, interactions, social forms, and a sense of community that fosters autonomy, personal interdependence, and positive social change. The analysis of the projects is based on a framework consisting of four elements: material support, social interaction, ordinary social forms, and the sense of community.The latter is a crucial component of convivial aesthetic: by fostering a feeling of belonging and shared purpose, participants become part of a larger social community with collective goals. Designers use symbols, rituals, and events to strengthen this sense of community.The paper acknowledges the limitations of this framework, particularly its focus on smaller communities and the need for further exploration of larger societal structures. However, it highlights the value of convivial aesthetic in shifting the focus of design from physical objects to immaterial interactions and social forms, ultimately promoting positive social transformation
