Space and Time Averaged Quantum Stress Tensor Fluctuations
2021
We extend previous work on the numerical diagonalization of quantum stress tensor operators in the Minkowski vacuum state, which considered operators averaged in a finite time interval, to operators averaged in a finite spacetime region. Since real experiments occur over finite volumes and durations, physically meaningful fluctuations may be obtained from stress tensor operators averaged by compactly supported sampling functions in space and time. The direct diagonalization, via a Bogoliubov transformation, gives the eigenvalues and the probabilities of measuring those eigenvalues in the vacuum state, from which the underlying probability distribution can be constructed. For the normal-orde…
An exploration of organization dissent and workplace freedom of speech among young professional intra-urban migrants in Shanghai
2017
This study explores the factors influencing the dissent behavior and perceptions of workplace freedom of speech among young Chinese professionals who are intra-urban migrants. It attempts to grasp the role of the Chinese household registration system, referred to as Hukou, in migrants’ professional and everyday life. Fourteen interviews were conducted with young, well-educated intra-urban migrants who possessed middle-income jobs but did not possess a Shanghai registration (Hukou). This study reveals that traditional Confucian values are significant in shaping Chinese migrant workers’ expressions of dissent and perceptions of workplace freedom of speech. Findings from this study demonstrate…
Democrazia deliberativa e Convenzione europea dei diritti umani
2010
Deliberative democracy and the European Convention on Human Rights Theories of deliberative democracy have rapidly become very popular amongst political scientists. The central argument of these theories is that democratic legitimacy of lawmaking does not lie (or does not only lie) in the elected character of Parliaments but in public delib- eration processes. Decisions have to be justified by reasons and reasons have to be publicly debated. Legitimacy also depends on the opportunity for citizens to participate effectively in public debates. In this paper I argue that the European Court of Human Rights can be a key player in promoting a democracy based on public deliberation and that in the…
Quasi-Lie Brackets and the Breaking of Time-Translation Symmetry for Quantum Systems Embedded in Classical Baths
2018
Many open quantum systems encountered in both natural and synthetic situations are embedded in classical-like baths. Often, the bath degrees of freedom may be represented in terms of canonically conjugate coordinates, but in some cases they may require a non-canonical or non-Hamiltonian representation. Herein, we review an approach to the dynamics and statistical mechanics of quantum subsystems embedded in either non-canonical or non-Hamiltonian classical-like baths which is based on operator-valued quasi-probability functions. These functions typically evolve through the action of quasi-Lie brackets and their associated Quantum-Classical Liouville Equations, or through quasi-Lie brackets a…
Visual Servoing Based on Shifted Moments
2015
Over the past decade, image moments have been exploited in several visual servoing schemes for their ability to represent object regions, objects defined by contours or a set of discrete points. Moments have also been useful to achieve control decoupling properties and to choose a minimal number of features to control the whole degrees of freedom (DOFs) of a camera. However, the choice of moment-based features to control the rotational motions around the $x$ -axis and $y$ -axis simultaneously with the translational motions along the same axis remains a key issue. In this paper, we introduce new visual features computed from low-order “shifted moments invariant.” Importantly, they allow us 1…
Immigrati e diritti sociali: parità di trattamento e tutela multilivello
2017
Il saggio analizza la tutela antidiscriminatoria di cui godono i lavoratori immigrati all'insegna di una prospettiva multilivello: più in particolare viene descritto il complesso di strumenti normativi del diritto nazionale ed europeo a tutela delle situazioni giuridiche soggettive degli immigrati (ad es., in materia di sicurezza sociale), per come interpretato dalla Corte Costituzionale, dalla Corte di Giustizia e dalla Corte EDU. Da ultimo, vengono analizzati i recenti orientamenti giurisprudenziali, che oscillano tra l'affievolimento del principio paritario in ragione di sempre più stringenti vincoli di bilancio, e la tendenziale parificazione tra cives e non cives alla luce del principi…
L’INSINDACABILITÀ FRA EQUILIBRIO DEI POTERI ED UGUAGLIANZA DEI DIRITTI
2010
RESUMEN El Estado italiano ha sido condenado por el Tribunal Europeo de Derechos Humanos por la violación del artículo 6.1 del Convenio, en todos aquellos casos relativos a la prerogativa de la inviolabilidad (insindacabilità) parlamentaria prevista en el artículo 68.1 de la Constitución. Atendiendo al dato apuntado, puede afirmarse que la necesaria garantía del principio de separación de poderes, en tanto que elemento esencial de la “arquitectura constitucional” viene a colisionar con la protección de los derechos fundamentales, al desconocer las exigencias derivadas del principio de proporcionalidad. El caso de la inviolabilidad italiana parece desviarse, por lo que a su aplicación se ref…
Degrees of freedom effect on fragmentation in tandem mass spectrometry of singly charged supramolecular aggregates of sodium sulfonates
2012
The characteristic collision energy (CCE) to obtain 50% fragmentation of positively and negatively single charged noncovalent clusters has been measured. CCE was found to increase linearly with the degrees of freedom (DoF) of the precursor ion, analogously to that observed for synthetic polymers. This suggests that fragmentation behavior (e.g. energy randomization) in covalent molecules and clusters are similar. Analysis of the slope of CCE with molecular size (DoF) indicates that activation energy of fragmentation of these clusters (loss of a monomer unit) is similar to that of the lowest energy fragmentation of protonated leucine-enkephalin. Positively and negatively charged aggregates be…
O DIREITO À LIBERDADE PESSOAL E A DETENÇÃO ADMINISTRATIVA DOS IMIGRANTES IRREGULARES E CLANDESTINOS NA ITÁLIA
2015
Na Itália, como em outros Estados da União Europeia, vem ocorrendo recentemente o fenômeno da “detenção administrativa” dos cidadãos estrangeiros irregulares, bem como dos requerentes de asilo, a maioria proveniente da África, do Oriente Médio e da Península Balcânica. Esses imigrantes, pelo simples fato de terem ingressado irregularmente no território europeu, apesar da imigração ilegal não constituir delito, são privados da liberdade pessoal ou de circulação e permanência, sendo detidos pelas autoridades de segurança pública, às vezes sem a validação da autoridade jurisdicional, durante um período de tempo também muito prolongado, em determinados locais, formais o…
"Utopia socialista" o "società post-secolare"? Percorsi francofortesi
2017
In this paper I will compare A. Honneth’s neo-socialist project with J. Habermas’ proposal of a post-secular society. Since both of these approaches are aimed to contrast with neoliberal theories, I will give explanation of my preference for Habermas’. I will do that by considering the relationship between the concepts of utopia, liberty and society.
