Street art in urbe. Arte urbana nelle periferie romane

Rome in the past was the undisputed cradle of the arts, the imperative destination of the eighteenth-century grand tourists for its constant combination of old and new, humble and magnificent, forgotten and alive that made it unique in its picturesque being, as the Englishmen called it. Recently, Rome is playing once again that key role in the 21st century world. The scenario is mostly regarding the Roman suburbs, borderline not only geographically, but also culturally and socially, where external ugliness is often due to an original lack of aesthetic design or frequently subjects to carelessness and degradation. On this type of urban contest many street artists are involved with their works, directly in contact with the territory and its inhabitants. In this essay the focus is on the connection born from the involvement of artists and citizens, which leads to a legal, programmatic and connected artistic production. So, Art becomes a means of communication in places that are often voiceless and, at the same time, it always performs its function: trough the Beauty, Art re-qualifies and educates and in the meantime interacts with the various components of society, stimulating knowledge and civic sense of common good

Mismatch in the Classification of Linear Subspaces: Sufficient Conditions for Reliable Classification

This paper considers the classification of linear subspaces with mismatched classifiers. In particular, we assume a model where one observes signals in the presence of isotropic Gaussian noise and the distribution of the signals conditioned on a given class is Gaussian with a zero mean and a low-rank covariance matrix. We also assume that the classifier knows only a mismatched version of the parameters of input distribution in lieu of the true parameters. By constructing an asymptotic low-noise expansion of an upper bound to the error probability of such a mismatched classifier, we provide sufficient conditions for reliable classification in the low-noise regime that are able to sharply predict the absence of a classification error floor. Such conditions are a function of the geometry of the true signal distribution, the geometry of the mismatched signal distributions as well as the interplay between such geometries, namely, the principal angles and the overlap between the true and the mismatched signal subspaces. Numerical results demonstrate that our conditions for reliable classification can sharply predict the behavior of a mismatched classifier both with synthetic data and in a motion segmentation and a hand-written digit classification applications.Comment: 17 pages, 7 figures, submitted to IEEE Transactions on Signal Processin

Language and Identity of the British Indian Teenage Diaspora: Gautam Malkani’s Londonstani, a case study

The work aims to shed some light on the role of language during a crucial step of life when it comes to identity, that is to say youth – the age of uncertainty par excellence, in which every convention, every belief is put into question and re-elaborated. Moreover, the analysis will focus on the teenagers of the British Indian diasporic community, for whom the research of an identity also includes the definition of belonging. In this reconnaissance phase, the issue will be tackled by reading Gautam Malkani’s debut novel, Londonstani (2006). The amazing ability of Malkani is to disclose how the issue of identity is played into language – each attempt to find a definition, to establish or break bonds of belonging, to disobey institutions and to adapt to the rules of a subgroup. Language becomes more than just a tool to communicate: the means becomes the message, transcending its content. The most striking aspect of the language of the Londonstani teens is that they do not speak “pure” English nor Punjabi, but a language made of encounters, clashes, and hybridization. Malkani catapults the reader into a completely unknown linguistic and cultural reality, not making any effort to make the reader feel “comfortable.” Words and sentences from different languages and traditions, references coming from Indian and African American culture are constant and rarely explained. Malkani is there to overturn expectations and to show how many languages become one in a land, in a city (London) that is the symbol of diaspora, a great third space of negotiation and fragmentation, where identities are lost to be found again – new, multifaceted, unstable

Supplier Selection for Food Industry: A Combination of Taguchi Loss Function and Fuzzy Analytical Hierarchy Process

Supplier selection is an important part of supply chain management process by which firms identify, evaluate, and establish contracts with suppliers. Deciding the right supplier can be a complex task. As such, various criteria must be taken into account to choose the best supplier. This study focused on the supply in the packaging division of a food industry in Denpasar-Bali. A combination of Taguchi Loss Function and fuzzy-AHP (Analytical Hierarchy Process Fuzzy Linear Programming) was used to determine the best supplier. In this analysis, several suppliers’ criteria were considered, namely quality, delivery, completeness, quality loss and environmental management. By maximizing the suppliers’ performances based on each criterion and aggregating the suppliers’ performances based on the overall criteria, the best supplier was determined.

Online Self Assessment and Peer Assessment of Students Teamwork: Evidence from Accounting Information System Discipline

This research was conducted to find out the extent to which a College Instructor can depend on peer evaluation of students as an accurate reflection of the contribution of each team member on the Team Project. This study used two approaches, namely quantitative and qualitative approaches. Quantitative approach is carried out to find out whether there is a difference between the assessment of group friends during the process of making project report and performance of their teamwork during the presentation. This is to see whether the assessment by the lecturers is sufficient to assess the contribution of each team member. Then, to find out if the Peer Assessment is fair, the Peer Assessment will be compared to Self-Assessment, whereby students were given the opportunity to assess their own contributions in the Team. Qualitative approach is carried out to see how students perceive the implementation of Peer assessment and Self-Assessment to determine the contribution of each member to the Team.
