Those Are Lasers That Were Their Eyes
2019
In a Cultural Studies perspective, this essay proposes an intertextual reading of sea-change and representations of the Moor in literature, folklore, visual and decorative arts, and fashion theory studies, as interpreted by William Shakespeare, the artist duo Invernomuto, and fashion designers Dolce & Gabbana.
Characterizations of {K,s+1}-Potent Matrices and Applications
2012
Recently, situations where a matrix coincides with some of its powers have been studied. This kind of matrices is related to the generalized inverse matrices. On the other hand, it is possible to introduce another class of matrices that involve an involutory matrix, generalizing the well-known idempotent matrix, widely useful in many applications. In this paper, we introduce a new kind of matrices called {K,s+1}-potent, as an extension of the aforementioned ones. First, different properties of {K,s+1}-potent matrices have been developed. Later, the main result developed in this paper is the characterization of this kind of matrices from a spectral point of view, in terms of powers of the ma…
Circular Economy and Value Creation: Sustainable Finance with a Real Options Approach
2021
This paper presents a methodological proposal that integrates the circular economy concept and financial valuation through real options analysis. The Value Hill model of a circular economy provides a representation of the course followed by the value of an asset. Specifically, after the primary use, the life of an asset may be extended by going through four phases: the 4R phases (Reuse, Refurbish, Remanufacture and Recycle). Financial valuation allows us to quantify value creation from firms’ asset circularity under uncertainty, modelled by binomial trees. Furthermore, the 4R phases are valued as real options by applying no-arbitrage opportunity arguments. The major contribution of this pap…
Representation of physical activity domains and sedentary behaviors across categories of gender and disability in children’s TV cartoons
2018
Television (TV) cartoons could reflect and shape social values about children’s health-related behaviors. The main aim of this study is to analyze the portrayal of physical activity (PA) domains in the most popular Spanish children’s television (TV) cartoons. It is performed a content analysis of each scene following a coding scheme. The sample selected included the five most popular children’s TV cartoons for the 2013-2014 period in Spain. Our results show a large gap between the modest representation of different PA domains compared to the overwhelming depiction of sedentary behaviors. We do not find evidence of males and females participating equally in a variety of PA domains, and we fa…
The equilibrium structure and fundamental vibrational frequencies of dioxirane
1998
Complete sets of quadratic and cubic force constants calculated for four isotopomers of dioxirane (CH2OO) are used to estimate vibration-rotation interaction contributions to observed values of rotational constants (B″), thereby yielding empirical estimates of the corresponding equilibrium values (Be). At the highest levels of theory, least-squares refinements of atomic coordinates to both the empirical Be values and the associated isotope shifts yield consistent sets of structural parameters. Recommended values are re(CO)=1.3846±0.0005 A; re(OO)=1.5133±0.0005 A; re(CH)=1.0853±0.0015 A and θe(HCH)=117.03±0.20°. Semidiagonal quartic force constants (in the normal coordinate representation) a…
Preliminary investigations on indirect competition among Italian employers’ associations, and the relevant effects on collective bargaining
2022
Le associazioni dei datori di lavoro sono attori importanti per il sistema delle relazioni industriali e della contrattazione collettiva. I datori di lavoro e i sindacati in genere negoziano gli standard di lavoro in termini di salari e condizioni di lavoro per conto rispettivamente delle aziende associate e dei dipendenti. Sebbene la maggior parte della letteratura sulle relazioni industriali si sia concentrata principalmente sulla forza associativa e sulla densità associativa delle associazioni dei datori di lavoro, in questa pubblicazione a cura di Michele Faioli e Silvio Bologna, gli autori si discostano da questa prospettiva e si concentrano sul funzionamento e sulla governance, ovvero…
Jason Intentional Learning: An Operational Semantics
2013
This paper introduces an operational semantics for defining Intentional Learning on Jason, the well known Java-based implementation of AgentSpeak(L). This semantics enables Jason to define agents capable of learning the reasons for adopting intentions based on their own experience. In this work, the use of the term Intentional Learning is strictly circumscribed to the practical rationality theory where plans are predefined and the target of the learning processes is to learn the reasons to adopt them as intentions. Top-Down Induction of Logical Decision Trees (TILDE) has proved to be a suitable mechanism for supporting learning on Jason: the first-order representation of TILDE is adequate t…
Subject, World and Value
2010
El punto de partida del artículo es el siguiente: Wittgenstein determinó su propósito de trazar un límite a la expresión lingüística del pensamiento sirviéndose, en cierta manera, de la distinción entre representación y voluntad con que Schopenhauer había reinterpretado la distinción kantiana entre el fenómeno y la cosa en sí. Al igual que Schopenhauer, Wittgenstein sostiene que el mundo de la ciencia corresponde al fenómeno, al mundo como ‘representación’, al mundo de los hechos; e igualmente considera que todo cuanto tiene que ver con los asuntos de máxima importancia y valor para nosotros —el sentido de nuestra existencia o de la existencia del mundo, la relación entre el sujeto de la vo…
Verbal and visual representations in task redesign: how different viewpoints enter into information systems design discussions
2005
We explore an important phase of information systems design (ISD), namely task redesign, and especially how different viewpoints enter into the dis- cussions. We study how one particular visual representation, a process diagram, is interpreted and how alternative, even competing, representations are produced verbally. To tie the visual and verbal representations and the representational prac- tices to wider social practices, we develop and use the Extended Three-dimen- sional Model of discourse. Visual representations emerged as focal in bringing in the different viewpoints and as reference points for discussions. Our model pro- vided a focused and powerful means to unveil for the outside r…
The role of social report for performance measurement of museums: an Italian survey from the web
2017
This paper aims to explore the concept of performance in the museum field, in particular whether and how it could find an adequate representation through social reporting tools. The social reports, indeed, in non-profit and public sector organisations are typically considered the main tools for institutional communication. To investigate on this topic, we analyse the social reports of some Italian museums using the content analysis in order to understand how the performance is evaluated and communicated. The empirical findings show how the reports are not fully able to represent the performance of the museums.
