Periodic Sequences of Arbitrage: A Tale of Four Currencies

This paper investigates arbitrage chains involving four currencies and four foreign exchange trader-arbitrageurs. In contrast with the three-currency case, we fi nd that arbitrage operations when four currencies are present may appear periodic in nature, and not involve smooth convergence to a \balanced" ensemble of exchange rates in which the law of one price holds. The goal of this article is to understand some interesting features of sequences of arbitrage operations, features which might well be relevant in other contexts in finance and economics.

Experiences with the control of schistosomiasis mansoni in two foci in Central Africa

Experiences with population-based chemotherapy and other methods for the control of schistosomiasis mansoni in two subsaharan foci are described. In the forest area of Maniema (Zaire), intense transmission of Schistosoma mansoni, high prevalences and intensities of infection, and important morbidity have been documental. Taking into account the limited financial means and the poor logistic conditions, the control strategy has been based mainly on targeted chemotherapy of heavily infected people (>600 epg). After ten years of intervention, prevalences and intensities have hardly been affected, but the initial severe hepatosplenic morbidity has almost disappeared. In Burundi, a national research and control programme has been initiated in 1982. Prevalences, intensities and morbidity were moderate, transmission was focal and erratic in time and space. A more structural control strategy was developed, based on screening and selective therapy, health education, sanitation and domestic water supply. Prevalences and intensities have been considerably reduced, though the results show focal and unpredicatable variations. Transmission and reinfection were not signifcantly affected by chemotherapy alone, and eventual outcome of repeated selective treatment appears to be limited by the sensitivity of the screening method. Intestinal morbidity was strongly reduced by community-based selective treatment, but hepatosplenic enlargement was hardly affected; this is possibly due to the confounding impact of increasing malaria morbidity. The experiences show the importance of local structures and conditions for the development of an adapted control strategy. It is further concluded that population-based chemotherapy is a highly valid tool for the rapid control of morbidity, but should in most operational conditions not be considered as a tool for transmission control.

A sure house studies on the dynastic promise to David in the books of Samuel

The dissertation studies the texts mentioning or alluding to the dynastic promise to David in the books of Samuel; in the concluding further perspectives it also overviews the occurrences of the promise in the books of Kings; in the appendix, it comments on the "Law of the King" in Deut 17,14-20, the last verse of which may contain an allusion to the Davidic promise. The study engages with recent discussion on the history of the text of 2 Sam 7. In a detailed textual commentary, it treats with all the differences between the main textual witnesses of the chapter, and apart from the evaluation of the individual variants, it attempts to answer the question whether the differences are due exclusively to the process of transmission, or they are of literary character. Special attention is paid to the value of 1 Chr 17 for the reconstruction of the oldest text of 2 Sam 7; the author hopes that the conclusions of this part of the dissertation may prove to be of some importance for a more general study of the reception of Samuel in Chronicles. The subsequent literary analysis of 2 Sam 7 and the other passages referring to the dynastic promise to David leads to two alternative datings of Nathan's oracle and consequently two alternative redactional hypotheses trying to give account of the emergence of the examined passages. In the concluding perspectives, the function of the promise in Samuel is compared with the occurrences of the motif in Kings; this comparison leads to tentative conclusions concerning the development of the relation of the two books.

Problemes derivats de la incidència de les normes europees en el Dret penal dels Estats membres

Projecte de recerca elaborat a partir d’una estada al Universitat de Bonn, Alemanya, entre juliol i desembre del 2008. Aquesta investigació conté algunes observacions sobre el fenomen de l’europeització del Dret penal dels Estats membres de la Unió Europea. En particular, tracta de profunditzar en les implicacions de la vinculació del legislador penal nacional tant a les regulacions europees com al principi de proporcionalitat i d’altres principis essencials del Dret penal. En primer lloc, la investigació descriu els instruments normatius que permeten a la Comunitat Europea i a la Unió Europea influir en el Dret penal dels Estats membres. Després, la investigació se centra en analitzar el exemple dels §§ 232 i 233 Codi penal alemany, els quals implementen la Decisió marc de 19 de juliol del 2002 respecte la lluita contra el tràfic d’éssers humans. En aquest cas, el legislador alemany ha complit els seus compromisos europeus, però no ha respectat el principi de proporcionalitat, ja que ha introduït incoherències dins el Dret penal alemany. Sobre la base dels resultats d’aquest anàlisi, aquesta investigació formula algunes propostes per una adequada “europeització” del Dret penal dels Estats membres de la Unió Europea i, en particular, per a una adequada tècnica legislativa dels Estats membres. En aquest context, el treball emfatitza la corresponsabilitat de la Comunitat Europea i la Unió Europea, per una banda, i els Estats membres, per l’altra, en aquest procés d’europeització. Per últim, la investigació conclou amb algunes observacions sobre la coordinació de la política criminal europea amb les polítiques criminals dels Estats membres.

El perdó de l’ofés: la via adecuada per alleugerir les càrregues de la justícia? Estudi de la institució i de les alternatives per rendibilitzar els recursos de l’Administració de justícia

En aquesta recerca aportem les conclusions de la nostra investigació sobre la figura del perdó de l’ofès i la seva possible virtualitat com a mitjà per alleugerir l’Administració de Justícia. En primer lloc, analitzem la institució del perdó de l’ofès, en concret, la seva regulació en el nostre Codi penal, els seus antecedents històrics i aportem certes dades de Dret comparat que poden ajudar a l’estudi crític de la institució (1). En la segona part, estudiem els arguments a favor i en contra del perdó de l’ofès dins el sistema penal i ens pronunciem sobre la seva legitimitat com a mecanisme per rendibilitzar l’Administració de Justícia (2). En la tercera part, sobre la base de les conclusions anteriors, aportem una reflexió sobre les alternatives al perdó de l’ofès (3). Per últim, en la darrera part, formulem la nostra proposta final sobre els mecanismes per rendibilitzar els recursos de l’Administració de Justícia (4). Segons el nostre estudi, el perdó de l’ofès no és un bon mecanisme per alleugerir la feina de l’Administració de Justícia. En canvi, la reparació i la conciliació si poden operar com a substitutius de la pena en els supòsits de delictes de menor gravetat; en els processos penals per aquests delictes caldria introduir un intent obligatori de conciliació, com el del § 380 StPO alemany i, a més, convindria preveure en el Codi penal la facultat del jutge d’eliminar la responsabilitat penal en determinats supòsits de reparació de l’autor a la víctima del delicte.

Quantifying rock fabrics: a test of autocorrelation of the spatial distribution of cristals

A novel test of spatial independence of the distribution of crystals or phases in rocksbased on compositional statistics is introduced. It improves and generalizes the commonjoins-count statistics known from map analysis in geographic information systems.Assigning phases independently to objects in RD is modelled by a single-trial multinomialrandom function Z(x), where the probabilities of phases add to one and areexplicitly modelled as compositions in the K-part simplex SK. Thus, apparent inconsistenciesof the tests based on the conventional joins{count statistics and their possiblycontradictory interpretations are avoided. In practical applications we assume that theprobabilities of phases do not depend on the location but are identical everywhere inthe domain of de nition. Thus, the model involves the sum of r independent identicalmultinomial distributed 1-trial random variables which is an r-trial multinomialdistributed random variable. The probabilities of the distribution of the r counts canbe considered as a composition in the Q-part simplex SQ. They span the so calledHardy-Weinberg manifold H that is proved to be a K-1-affine subspace of SQ. This isa generalisation of the well-known Hardy-Weinberg law of genetics. If the assignmentof phases accounts for some kind of spatial dependence, then the r-trial probabilitiesdo not remain on H. This suggests the use of the Aitchison distance between observedprobabilities to H to test dependence. Moreover, when there is a spatial uctuation ofthe multinomial probabilities, the observed r-trial probabilities move on H. This shiftcan be used as to check for these uctuations. A practical procedure and an algorithmto perform the test have been developed. Some cases applied to simulated and realdata are presented.Key words: Spatial distribution of crystals in rocks, spatial distribution of phases,joins-count statistics, multinomial distribution, Hardy-Weinberg law, Hardy-Weinbergmanifold, Aitchison geometry

Statistical similarity between the compression of a porous material and earthquakes

It has been long stated that there are profound analogies between fracture experiments and earthquakes; however, few works attempt a complete characterization of the parallelisms between these so separate phenomena. We study the Acoustic Emission events produced during the compression of Vycor (SiO&sub&2&/sub&). The Gutenberg-Richter law, the modified Omori's law, and the law of aftershock productivity hold for a minimum of 5 decades, are independent of the compression rate, and keep stationary for all the duration of the experiments. The waiting-time distribution fulfills a unified scaling law with a power-law exponent close to 2.45 for long times, which is explained in terms of the temporal variations of the activity rate.

Serving Iowa Youth and Families with a Youth Development Approach : JJDP Act Formula Grant Application and Three-Year Comprehensive Plan

This report is Iowa’s Three-Year Plan, which serves as the application for federal Juvenile Justice and Delinquency Prevention Act formula grant funding (JJDP Act). The Division of Criminal and Juvenile Justice Planning (CJJP) wrote Iowa’s Three-Year Plan. CJJP is the state agency responsible for administering the JJDP Act in Iowa. Federal officials refer to state administering agencies as the state planning agency (SPA). The Plan was developed and approved by Iowa’s Juvenile Justice Advisory Council. That Council assists with administration of the JJDP Act, and also provides guidance and direction to the SPA, the Governor and the legislature regarding juvenile justice issues in Iowa. Federal officials refer to such state level groups as state advisory groups (SAG’s). The acronyms SPA and SAG are used through this report.
