Description:
On the basis of a previously reported spectroscopic and petrographic database, a general procedure for determining the provenance of white marbles is presented and used to establish a classification rule for the marbles most used in Roman architecture. The rule, based on a data set including seven groups (Carrara, Naxos, Paros, Pentelicon, Proconnesus and Thasos, calcitic and dolomitic marbles) and 712 samples, uses quadratic discriminant analysis and a set of four spectroscopic and two petrographic variables, after logarithmic transformation. The performance of the rule, obtained by resubstitution, is 93.3%. Validation of this result, carried out using the bootstrap technique, after briefly introducing the method, indicates that the resubstitution bias is 1.4%, with a final unbiased performance of about 92%. The bootstrap result agrees satisfactorily with alternative bias estimates (jackknife, cross-validation). Problems connected with the assignment of sets of unknown samples and the methods used for distinguishing reliable from doubtful assignments are discussed. ... Read more

Dust jacket notes: Because of the richness and attractiveness of the personality of John XXIII, most books on him have concentrated on the character of the man, on his simplicity, his wit, his kindness. While it is fitting that so universally appealing a figure as that of the late Pope should be seen in its fullest humanity, it is equally fitting that his work as ruler of the Church should be appreciated. The present work focuses on this latter aspect of Pope John and provides a concise but thoroughly documented history of his reign. In addition to such highlights of his pontificate as the two great social encyclicals and the convening of the Second Vatican Council, this book records in detail all of the various events which constituted Pope John's program for--as he himself said--"making the Church move with the tides of history." Here is the story of the Roman synod, of the Secretariat for Promoting Christian Unity, of the extension of the use of the vernacular in the liturgy, of the Pope's effort to reform seminary training, of his deep concern for the poor, of his willingness to engage in dialogue with Communists, of his interest in the Christian East and in the missions--in short, of all those events which put the word "aggiornamento" into everyone's daily speech. This historical survey is supplemented by all of the statements that Pope Paul has made on the life and work of John XXIII. In these statements is reflected the great reverence which the present pontiff [Pope Paul VI] feels towards Pope John. ... Read more

Description:
We investigate the effects of the drastic tariff reductions of the 1980s and 1990s in Colombia on the wage distribution. We identify three main channels through which the wage distribution was affected: increasing returns to college education, changes in industry wages that hurt sectors with initially lower wages and a higher fraction of unskilled workers, and shifts of the labor force towards the informal sector that typically pays lower wages and offers no benefits. Our results suggest that trade policy played a role in each of the above cases. The increase in the skill premium was primarily driven by skilled-biased technological change; however, our evidence suggests that this change may have been in part motivated by the tariff reductions and the increased foreign competition to which the trade reform exposed domestic producers. With respect to industry wages, we find that wage premiums decreased by more in sectors that experienced larger tariff cuts. Finally, we find some evidence that the increase in the size of the informal sector is related to increased foreign competition-sectors with larger tariff cuts and more trade exposure, as measured by the size of their imports, experience a greater increase in informality, though this effect is concentrated in the years prior to the labor market reform. Nevertheless, increasing returns to education, and changes in industry premiums and informality alone cannot fully explain the increase in wage inequality we observe over this period. This suggests that overall the effect of the trade reforms on the wage distribution may have been small. ... Read more
