Pietro Verri’s Contribution to the Economic Theory of the 18th Century: Commercial Society, Civil Society and Governance of the Economy
Full text link'Count Pietro Verri (1728-97) - Schumpeter writes (History, p. 178) - - would have to be included in any list of the greatest economists'. Within the Milanese school, he certainly stands out, alongside with Cesare Beccaria, during one of the most interesting periods from a history of analysis point of view. Luigi Cossa's famous introduction to the study of political economy rates Pietro Verri to be inferior to Beccaria in ingenuity and scientific cultivation, but greatly to be ahead of him as an economist.1 This judgement by Cossa, in particular, seems to echo the relative position of the two men in the history of ideas, particularly after Beccaria's rise to fame with a book - On crimes and punishments - which had in fact been largely inspired by Verri himself and defended by him.2 It is proposed in the present paper to revisit some of the basic tenets of Pietro Verri's political economy, with more in view than dwell on specific intuitions and theorems: namely relate those to Verri's own - quite original - conception of the economy. The scholarly work of Pietro Verri - with a special reference to his Meditazioni sulla economia politica of 1771 - provides the first systematic contribution stemming from the quarters of Lombard enlightenment in the field of political economy, especially so if one considers that Cesare Beccaria's parallel work - namely his Elementi di economia pubblica, conceived and drafted at the same time as Verri's Meditazioni - would only be published posthumously several years later. From the vantage point afforded by Verri's political economy, we gain a considerably attractive view of the most significant elements and characteristic concepts of Lombard enlightenment during the latter half of the 18th century; Verri, moreover, as we shall see, builds on a number of them in a new and original way. This paper is aimed at discussing Verri's political economy mainly along two distinct, but related, lines. In the first place the conception of commercial society is considered such as it is treated by the author particularly in his Meditazioni. In this perspective the analysis of such issues as competition and the market or money and taxation occupy a central place. Secondly it will be necessary to emphasise that Verri's approach has little to do either with forms of pure economics on one side - largely yet to be born throughout the 18th century - or, on the other side, with such conceptions of the polis - contrariwise well alive among his own contemporaries - as are founded on a sovereign authority conceived to be situated above the law. What Verri's political economy ultimately amounts to is an economic conception of civil society. The latter has natural strong connections with his own fact-mindedness - emphasised by Schumpeter - as well as with his deep practical involvement in administrative affairs and in the reforming process taking place during the latter half of the 18th century in Milan. In our view, a thorough investigation along the mentioned lines is the precondition for an understanding of the intellectual stature and of the scholarly contribution of Pietro Verri. His main ground is distinctly analytical and only by appreciating his analysis is it possible to shed light on the meaning and intellectual significance also of his practical contributions. Moreover Verri's pronouncements on the criticism of despotic government, the relevance of intermediate powers or bodies and on multiple levels of governance will be examined in a new and original light, showing how close they are to the gist of his analysis.

Bayesian nonparametric predictive inference and bootstrap techniques
No full textWe address the question as to whether a prior distribution on the space of distribution functions exists which generates the posterior produced by Efron's and Rubin's bootstrap techniques, emphasizing the connections with the Dirichlet process. We also introduce a new resampling plan which has two advantages: prior opinions are taken into account and the predictive distribution of the future observations is not forced to be concentrated on observed values
Complex Data Modeling and Computationally Intensive Statistical Methods
No full textThe last years have seen the advent and development of many devices able to record and store an always increasing amount of complex and high dimensional data; 3D images generated by medical scanners or satellite remote sensing, DNA microarrays, real time financial data, system control datasets. The analysis of this data poses new challenging problems and requires the development of novel statistical models and computational methods, fueling many fascinating and fast growing research areas of modern statistics. The book offers a wide variety of statistical methods and is addressed to statistic

About twin primes and distribution of primes
Full text linkThis paper give us a demonstration of twin primes conjecture using approximation of function �(iupsilon) that we introduce in section 6. Section 1-5 give us introduction to terminology and a clarification on (iupsilon) terms. In particular section
5 is really important because of its Lemma. Section 7 reassume foregoing explanations and it give us two theorems and one corollary;the theorem 7.2 give us exact approximation of twin primes counting function
