Lei e liberdade na ADPF 130: uma leitura da decisão a partir de Hannah Arendt

Esta dissertação pretende analisar criticamente o julgado da ADPF 130, a luz do pensamento político de Hannah Arendt, em razão de conduzir o debate do significado da imprensa idônea para a promoção da liberdade de expressão quando torna efetivo o princípio da publicidade na esfera pública. O pensamento da autora contribui para avaliar criticamente a racionalidade do Poder judiciário brasileiro na decisão da ADPF 130 pelo fato deste conceber de modo questionável a imprensa ter o papel democrático de ser formadora de opinião pública e de compreender que qualquer lei para regulamentar a atividade midiática implica automaticamente em cair no risco da censura prévia. No capítulo I, o trabalho sumariza as argumentações propostas na ADPF para indicar que a maioria dos votos dos ministros se situa a partir das concepções gerais do liberalismo e as suas consequências para atuação da imprensa na democracia brasileira. Em seguida, na primeira parte do capítulo II serão apresentadas as principais características do pensamento político de Arendt contempladas nas obras A condição humana e Origens do totalitarismo, em uma perspectiva de situá-las na tradição política do pensamento político ocidental, expondo, de forma geral, os contornos de seu sistema político, como: distinção entre domínio público e domínio privado, vita activa e doxa e função da lei. Assim, passa-se a analisar, em momento posterior no capítulo II as manifestações do pensamento arendtiano em torno da liberdade de expressão e a repercussão do seu significado na imprensa idônea. O capítulo III posiciona o pensamento arendtiano na tradição política do mundo ocidental. Nele, Arendt aponta quando a liberdade política que se manifesta entre o eu-posso e eu-quero se dissocia, o qual ocasiona obstáculos para a aparição da doxa no agir em concerto entre os homens. Assim, equivocadamente a política passa a ser vista apenas como um velho truísmo de assegurar a liberdade. Compreendemos que, neste contexto, a imprensa é concebida pela maioria dos votos dos ministros com o papel de ser formadora de opinião pública pelo fato de considerarem implicitamente que vivemos numa democracia onde os homens não participam efetivamente na vida pública.

Goppa codes through polynomials of B[X;(1/2^2)Z_0] and its decoding principle

In this paper, we present a decoding principle for Goppa codes constructed by generalized polynomials, which is based on modified Berlekamp-Massey algorithm. This algorithm corrects all errors up to the Hamming weight $t\leq 2r$, i.e., whose minimum Hamming distance is $2^{2}r+1$.

Precautionary principle, economic and energy systems and social equity

In this paper the precautionary principle is reviewed alongside the process of international implementation. Adoption of the precautionary principle is advocated to deal with energy choices as a mechanism to account for potential climate change impacts, notwithstanding the debate on scientific uncertainty on the links between solar activity, greenhouse gas concentration and climate. However, it is also recognized that the widespread application of the precautionary principle to energy choices does not seem to be taking place in the real world. Relevant concrete barriers are identified stemming from the intrinsic logic governing the hegemonic economic system, driving the energy choices by economic surplus and rent generation potential, the existence of social asymmetries inside and among societies as well as by the absence of democratic global governance mechanisms, capable of dealing with climate change issues. Such perception seems to have been reinforced by the outcome of the United Nations Climate Change Conference, held in Copenhagen in December 2009. (c) 2010 Elsevier Ltd. All rights reserved.

An extension of the invariance principle for dwell-time switched nonlinear systems

In this paper, we propose an extension of the invariance principle for nonlinear switched systems under dwell-time switched solutions. This extension allows the derivative of an auxiliary function V, also called a Lyapunov-like function, along the solutions of the switched system to be positive on some sets. The results of this paper are useful to estimate attractors of nonlinear switched systems and corresponding basins of attraction. Uniform estimates of attractors and basin of attractions with respect to time-invariant uncertain parameters are also obtained. Results for a common Lyapunov-like function and multiple Lyapunov-like functions are given. Illustrative examples show the potential of the theoretical results in providing information on the asymptotic behavior of nonlinear dynamical switched systems. (C) 2012 Elsevier B.V.

On Fermat's principle for causal curves in time oriented Finsler spacetimes

In this work, a version of Fermat's principle for causal curves with the same energy in time orientable Finsler spacetimes is proved. We calculate the second variation of the time arrival functional along a geodesic in terms of the index form associated with the Finsler spacetime Lagrangian. Then the character of the critical points of the time arrival functional is investigated and a Morse index theorem in the context of Finsler spacetime is presented.

Transcranial magnetic stimulation in mild to severe hemiparesis early after stroke: a proof of principle and novel approach to improve motor function

Low-frequency repetitive transcranial magnetic stimulation (rTMS) of the unaffected hemisphere can enhance function of the paretic hand in patients with mild motor impairment. Effects of low-frequency rTMS to the contralesional motor cortex at an early stage of mild to severe hemiparesis after stroke are unknown. In this pilot, randomized, double-blind clinical trial we compared the effects of low-frequency rTMS or sham rTMS as add-on therapies to outpatient customary rehabilitation, in 30 patients within 5-45 days after ischemic stroke, and mild to severe hand paresis. The primary feasibility outcome was compliance with the interventions. The primary safety outcome was the proportion of intervention-related adverse events. Performance of the paretic hand in the Jebsen-Taylor test and pinch strength were secondary outcomes. Outcomes were assessed at baseline, after ten sessions of treatment administered over 2 weeks and at 1 month after end of treatment. Baseline clinical features were comparable across groups. For the primary feasibility outcome, compliance with treatment was 100% in the active group and 94% in the sham group. There were no serious intervention-related adverse events. There were significant improvements in performance in the Jebsen-Taylor test (mean, 12.3% 1 month after treatment) and pinch force (mean, 0.5 Newtons) in the active group, but not in the sham group. Low-frequency rTMS to the contralesional motor cortex early after stroke is feasible, safe and potentially effective to improve function of the paretic hand, in patients with mild to severe hemiparesis. These promising results will be valuable to design larger randomized clinical trials.

Using Mitrofanoff's principle and Monti's technique as a surgical option for bladder augmentation with a continent stoma: a case report

Abstract Introduction Hydronephrosis, reflux and renal failure are serious complications that occur in patients with neurogenic bladder associated with myelomeningocele. When the bladder compliance is lost, it is imperative to carry out surgery aimed at reducing bladder storage pressure. An ileocystoplasty, and for patients not suitable for intermittent catheterization, using the Mitrofanoff principle to form a continent stoma and the subsequent closure of the bladder neck, can be used. We report here, for the first time to the best of our knowledge, an association between two previously described techniques (the Mitrofanoff principle and the technique of Monti), that can solve the problem of a short appendix in obese patients. Case presentation A 33-year-old male Caucasian patient with myelomeningocele and neurogenic bladder developed low bladder compliance (4.0 mL/cm H2O) while still maintaining normal renal function. A bladder augmentation (ileocystoplasty) with continent derivation principle (Mitrofanoff) was performed. During surgery, we found that the patient's appendix was too short and was insufficient to reach the skin. We decided to make an association between the Mitrofanoff conduit and the ileal technique of Monti, through which we performed an anastomosis of the distal stump of the appendix to the bladder (with an antireflux valve). Later, the proximal stump of the appendix was anastomosed to an ileal segment of 2.0 cm that was open longitudinally and reconfigured transversally (Monti technique), modeled by a 12-Fr urethral catheter, and finally, the distal stump was sutured at the patient's navel. After the procedure, a suprapubic cystostomy (22 Fr) and a Foley catheter (10 Fr) through the continent conduit were left in place. The patient had recovered well and was discharged on the tenth day after surgery. He remained with the Foley catheter (through the conduit) for 21 days and cystostomy for 30 days. Six months after surgery he was continent with good bladder compliance without reflux and fully adapted to catheterization through the navel. Conclusion The unpublished association between the Mitrofanoff and Monti techniques is feasible and a very useful alternative in urologic cases of derivation continent in which the ileocecal appendix is too short to reach the skin (i.e., in obese patients).

Product placement e libertà di espressione

Object of the search is the advertising phenomenon of the "product placement", with reference to that it has been investigated legality’s limits, as well as the relationship with the constitutionally protected liberty of expression. Particularly, it has been analyzed, in first place, the problem of the relationship between the freedom of expression and the liberty of economic initiative, with particular reference to the different circles of guardianship to these prepared: or, larger, the one provided for the first from the 21th article of Costitution, more circumscribed, instead, the one established in the 41th article of Costitution, with reference to the second. This analysis has been made with the purpose to investigate the coordination among such liberties in those forms of communications that, for the proper peculiarities that characterize them, can be qualified, according to the concrete circumstances in which they are spread, so much forms of liberty of expression, how much exercise of an activity of enterprise. Under this last profile, it has been taken attention on the advertising activity and, specially, on the non transparent publicities, or not immediately perceivable as such from their receivers, and, therefore, in contrast with the advertising trasparence’s principle: or, the so-called cases of hidden publicity, what the editorial publicity, both "in narrow sense" both "in general sense", as well as the phenomenon of the product placement (or positioning of product), by now diffused in the commercial routine. Therefore, it has been proceeded to a complete and exhaustive examination of innovations introduced by the recent legislative discipline in subject of “planned placement of marks and products” in the cinema works, appraising, in the specific one, the effects, juridical and no juridical, consequential from the introduction of a first form of regulation of the phenomenon of the product placement and, particularly, from the express provision about the legality of the use to such advertising, if it has realized according to specific requirements or condition. In relationship to such profile, it has been also investigate limits (sub kind of normative gaps) from which the recently introduced discipline in subject would seem characterized. Finally, a further circle of investigation has concerned the possible organization of the phenomenon under a negotiate aspect, as particular contract of advertising, in which the object consists in an promotional activity. Concerning this, the experience of foreign countries (above all the Anglo-Saxon one) has been very important, because of the absence, in our arrangement, of a general normative discipline about advertising contracts. Consequently, I’ve investigated principal characteristics of similar contracts, in first place the atypicalness, because of the lack, in Italy, of a legislative discipline of this contract. Such investigation has also been developed through a comparation between the positioning of product and the other advertising contracts, among which, particularly, the sponsorship, as well as the contracts for the advertising exploitation of the name and other people's image, and, specially, the contract of testimonial and the contract of endorsement.
