‘Due libertie and proportiond equalitie’: Milton, democracy, and the republican tradition

John Milton’s political thought has been interpreted in strikingly divergent ways. This article argues that he should be seen as a classical republican, and locates key aspects of his political thought within an ancient Greek discourse critical of democracy or extreme democracy. Milton was clearly familiar with the ancient texts expounding this critique, and he himself deployed both the arguments and the characteristic discourse of the anti-democratic thinkers across the span of his writing. This vision of politics emphasized the rightly-ordered soul of the masculine republican citizen, in contrast to the unruly passions seen both in tyrants and in the democratic rabble.

Do real balance effects invalidate the Taylor principle in closed and open economies?

This paper examines the determinacy implications of forecast-based monetary policy rules that set the interest rate in response to expected future inflation in a Neo-Wicksellian model that incorporates real balance effects. We show that the presence of such effects in closed economies restricts the ability of the Taylor principle to prevent indeterminacy of the rational expectations equilibrium. The problem is exacerbated in open economies, particularly if the policy rule reacts to consumer-price, rather than domestic-price, inflation. However, determinacy can be restored in both closed and open economies with the addition of monetary policy inertia.

Neural stem cells, inflammation and NF-kappaB: basic principle of maintenance and repair or origin of brain tumours?

Several recent reports suggest that inflammatory signals play a decisive role in the self-renewal, migration and differentiation of multipotent neural stem cells (NSCs). NSCs are believed to be able to ameliorate the symptoms of several brain pathologies through proliferation, migration into the area of the lesion and either differentiation into the appropriate cell type or secretion of anti-inflammatory cytokines. Although NSCs have beneficial roles, current evidence indicates that brain tumours, such as astrogliomas or ependymomas are also caused by tumour-initiating cells with stem-like properties. However, little is known about the cellular and molecular processes potentially generating tumours from NSCs. Most pro-inflammatory conditions are considered to activate the transcription factor NF-kappaB in various cell types. Strong inductive effects of NF-kappaB on proliferation and migration of NSCs have been described. Moreover, NF-kappaB is constitutively active in most tumour cells described so far. Chronic inflammation is also known to initiate cancer. Thus, NF-kappaB might provide a novel mechanistic link between chronic inflammation, stem cells and cancer. This review discusses the apparently ambivalent role of NF-kappaB: physiological maintenance and repair of the brain via NSCs, and a potential role in tumour initiation. Furthermore, it reveals a possible mechanism of brain tumour formation based on inflammation and NF-kappaB activity in NSCs.

Borderline cases and the collapsing principle

John Broome has argued that value incommensurability is vagueness, by appeal to a controversial ‘collapsing principle’ about comparative indeterminacy. I offer a new counterexample to the collapsing principle. That principle allows us to derive an outright contradiction from the claim that some object is a borderline case of some predicate. But if there are no borderline cases, then the principle is empty. The collapsing principle is either false or empty.

Basic Income, Republican Freedom, and Effective Market Power

This article examines republican arguments for a basic income that turn on a right to exit the labour market. It gives criteria for the maintenance of republican freedom in markets, arguing that a right to exit or effective market power will guarantee republican freedom in markets. The article then considers whether a basic income is either sufficient or necessary to protect republican freedom both in labour markets and elsewhere. If a basic income is necessary to protect republican freedom in the labour market, I argue it is not sufficient to protect that freedom elsewhere. If citizens lack the means to maintain their republican freedom in the labour market, then there may be other spheres of life where they are vulnerable to subordination, whether or not they have a basic income. Some sociological evidence on cultural consumption patterns is presented.

Generalized convective quasi-equilibrium principle

A generalization of Arakawa and Schubert's convective quasi-equilibrium principle is presented for a closure formulation of mass-flux convection parameterization. The original principle is based on the budget of the cloud work function. This principle is generalized by considering the budget for a vertical integral of an arbitrary convection-related quantity. The closure formulation includes Arakawa and Schubert's quasi-equilibrium, as well as both CAPE and moisture closures as special cases. The formulation also includes new possibilities for considering vertical integrals that are dependent on convective-scale variables, such as the moisture within convection. The generalized convective quasi-equilibrium is defined by a balance between large-scale forcing and convective response for a given vertically-integrated quantity. The latter takes the form of a convolution of a kernel matrix and a mass-flux spectrum, as in the original convective quasi-equilibrium. The kernel reduces to a scalar when either a bulk formulation is adopted, or only large-scale variables are considered within the vertical integral. Various physical implications of the generalized closure are discussed. These include the possibility that precipitation might be considered as a potentially-significant contribution to the large-scale forcing. Two dicta are proposed as guiding physical principles for the specifying a suitable vertically-integrated quantity.

Discontinuous local semiflows for Kurzweil equations leading to LaSalle`s invariance principle for differential systems with impulses at variable times

In this paper, we consider an initial value problem for a class of generalized ODEs, also known as Kurzweil equations, and we prove the existence of a local semidynamical system there. Under certain perturbation conditions, we also show that this class of generalized ODEs admits a discontinuous semiflow which we shall refer to as an impulsive semidynamical system. As a consequence, we obtain LaSalle`s invariance principle for such a class of generalized ODEs. Due to the importance of LaSalle`s invariance principle in studying stability of differential systems, we include an application to autonomous ordinary differential systems with impulse action at variable times.

First-principle data-driven models for assessment of motor disorders in Parkinson’s disease

Parkinson’s disease (PD) is an increasing neurological disorder in an aging society. The motor and non-motor symptoms of PD advance with the disease progression and occur in varying frequency and duration. In order to affirm the full extent of a patient’s condition, repeated assessments are necessary to adjust medical prescription. In clinical studies, symptoms are assessed using the unified Parkinson’s disease rating scale (UPDRS). On one hand, the subjective rating using UPDRS relies on clinical expertise. On the other hand, it requires the physical presence of patients in clinics which implies high logistical costs. Another limitation of clinical assessment is that the observation in hospital may not accurately represent a patient’s situation at home. For such reasons, the practical frequency of tracking PD symptoms may under-represent the true time scale of PD fluctuations and may result in an overall inaccurate assessment. Current technologies for at-home PD treatment are based on data-driven approaches for which the interpretation and reproduction of results are problematic.  The overall objective of this thesis is to develop and evaluate unobtrusive computer methods for enabling remote monitoring of patients with PD. It investigates first-principle data-driven model based novel signal and image processing techniques for extraction of clinically useful information from audio recordings of speech (in texts read aloud) and video recordings of gait and finger-tapping motor examinations. The aim is to map between PD symptoms severities estimated using novel computer methods and the clinical ratings based on UPDRS part-III (motor examination). A web-based test battery system consisting of self-assessment of symptoms and motor function tests was previously constructed for a touch screen mobile device. A comprehensive speech framework has been developed for this device to analyze text-dependent running speech by: (1) extracting novel signal features that are able to represent PD deficits in each individual component of the speech system, (2) mapping between clinical ratings and feature estimates of speech symptom severity, and (3) classifying between UPDRS part-III severity levels using speech features and statistical machine learning tools. A novel speech processing method called cepstral separation difference showed stronger ability to classify between speech symptom severities as compared to existing features of PD speech. In the case of finger tapping, the recorded videos of rapid finger tapping examination were processed using a novel computer-vision (CV) algorithm that extracts symptom information from video-based tapping signals using motion analysis of the index-finger which incorporates a face detection module for signal calibration. This algorithm was able to discriminate between UPDRS part III severity levels of finger tapping with high classification rates. Further analysis was performed on novel CV based gait features constructed using a standard human model to discriminate between a healthy gait and a Parkinsonian gait. The findings of this study suggest that the symptom severity levels in PD can be discriminated with high accuracies by involving a combination of first-principle (features) and data-driven (classification) approaches. The processing of audio and video recordings on one hand allows remote monitoring of speech, gait and finger-tapping examinations by the clinical staff. On the other hand, the first-principles approach eases the understanding of symptom estimates for clinicians. We have demonstrated that the selected features of speech, gait and finger tapping were able to discriminate between symptom severity levels, as well as, between healthy controls and PD patients with high classification rates. The findings support suitability of these methods to be used as decision support tools in the context of PD assessment.

Taylor principle and inflation stability in emerging market countriesw

The goal of this paper is to evaluate the validity of the Taylor principle for inflation control in 12 developing countries that use inflation targeting regimes: Brazil, Chile, Colombia, Hungary, Israel, Mexico, Peru, Philippines, Poland, South Africa, Thailand and Turkey. The test is based on a state-space model to determine when each country has followed the principle; then a threshold unit root test is used to verify if the stationarity of the deviation of the expected inflation from its target depends on compliance with the Taylor principle. The results show that such compliance leads to the stationarity of the deviation of the expected inflation from its target in all cases. Furthermore, in most cases, non-compliance with the Taylor principle leads to nonstationary deviation of the expected inflation.

Transparência, a resposta institucional à pressão social: o caso do Tribunal de Contas do Estado do Rio de Janeiro

The present work aims to identify emerging organizational changes in the Court of Accounts of the State of Rio de Janeiro - TCE/RJ that are happening in the contemporary scenery known as the Age of Information. The search for the comprehension of the institutional dynamics is oriented by concepts originated from the theory of complexity, which believe that the public services external control system can be understood in a political, technical and legal environment with growing levels of learning and innovation. While chasing the possible causes of these changes, we try to prove the hypothesis that the TCE/RJ is turning into a more transparent organization. For this purpose, we define the outlines and reaches of the principle of transparency, based in bibliographical and documental researches, and analyze the phenomenon perceived in a explanation research through semi-structured interviews performed with two groups: a sample representing the universe under jurisdiction entities top level directors and the other obtained in the universe of formal and informal leaderships existing in the educational body of the institution. The conclusion of the present work confirms the initial questions, indicating that the organization is really becoming more and more transparent. The social-technical changes that are happening today at the TCE/RJ are caused by the growing social pressure for more effective results in the control of public expenditures. Under the systemic point of view, we observe cracks in the protective bell-glass that evolves the institution - previously hermetic to the external contingencies and that works today as a SAC - Adaptive Complex System. Aspects such as organization structural changes, the introduction of strategic planning and the growing democratization of the decision process are producing a new organizational culture. The seniority of the Technical Headcount contributes to establish the pre-conditions for the development of a administration where the participation of the TCE/RJ technical employees adds importance to its development as an institution that generates republican effects in the society from its less hermetic decision process.

O piso salarial nacional: a valorização do professor na Constituição de 1988

The paper investigates the legal mechanisms used by the Legislature and the Executive to implement the constitutional principle of the teacher s minimum wage, which is proclaimed in the Constitution as a strategy of professional appreciation for this category. The text demonstrates that the legal mechanisms used to value the teacher were: the 1988 Constitution, the constitutional amendments to this Charter updated and modified the original text in relation to the matter, and finally, the Minimum Wage Law . Article nº 206 of 1988 s Federal Constitution established that basic education teachers, who work in public schools, would be entitled to a national minimum wage. Law nº 11.738/2008 ( Minimum Wage Law ) regulated the matter and made other determinations on the relationship between the State and the teachers such as the establishment of parameters for the distribution of the workload of teachers. Based on this law, since 2009 the minimum wage has been set annually by the Federal Government. However, state governments and municipalities throughout Brazil protested prescriptions contained in the Minimum Wage Law . In this context, some governors and mayors led the Supreme Court regarding the constitutionality of this law. The complainants considered that there was unconstitutional by the following: definition of the teacher s workday, which in the complainants point of view was competence of local governments; ensuring that teachers receive salaries tied to the minimum wage with retroactive effect; transformation of the minimum wage in basic salary, lack of sufficient budget in the states and municipalities to honor with the new values to be paid to teachers and, finally, determining workload for the teacher to perform other activities besides classroom activities. At the trial held at the STF the majority of Ministers rejected the claim and considered that the Minimum Wage Law , taken together, was constitutional. However, this decision did not alter the position of the managers or the interpretation of the ministers who agreed with the unconstitutionality of some aspects of the law. This means that one law can present differences in interpretation between ordinary people and among members of the Judiciary. The search showed the following conclusions: the law is not a definitive parameter of justice, because it is deeply linked to various interests; the development, implementation, and judgment of laws dealing with minimum wage of teaching are linked to historical and cultural aspects of society; the demand for enhancement of teacher and setting a minimum wage has only emerged in the late twentieth century, a fact explained in this work based on data that indicate the recent concern of Brazilian State with schooling a phenomenon typically Republican and with the professionalization of teaching emerging concern from the knowledge society; the Legislative and Executive search mechanism to implement the minimum wage of the teachers because of the contemporary need for professionalization of teaching

A missão política do Supremo Tribunal Federal: análise de sua importância como corte constitucional para o controle do poder no Brasil

The following study proposes an analysis of the politic process which the brazilian constitutional justice faces, emphasizing the Supremo Tribunal Federal . For that purpose, we start by examining the intimate relationship between Politics and Law, in view of the most recent social systems theories, so that the political system is distinguished by the exclusiveness of using the physical force, intending to make coletive tying decisions, and the juridical system as a congruent generalization of the expectations towards the rules and principles, brought together under an interdependence by which both gather legitimacy and effectiveness. In this manner we can notice the political effects of the constitutional interpretation conducted by Judges as well as by other juridical professionals, because these ones decrease the overload of expectations which are pointed to the Judicature. Constitutional interpretation is democratized since the participative democracy arises and stablishes a permanent state of awareness around the exercise of power and favours the preservation of the pluralism (counter-majoritary principle) where we can find the origin of the democratic nature of constitutional courts, once, in most cases, their members are not elected by the people. After that, we analyse the historical posture of the Supremo Tribunal Federal as a constitutional court in Brazil, so we can realize the attempts to make it vulnerable to the appeals of governability and economical aims, agains which this court somehow has resisted, stressing its particularities. At the end, it s concluded that even the so-called acts of government, whose judiciary control is mostly repelled, are subjected to a constitutional analysis, last frontier to be explored by the Supremo Tribunal Federal in its role of exposing our republican Constitution
