Democracy, fundamental rights and public finance: a constitutionalist criticism of the Steuerle-Roeper Index

The article proposes to critically discuss the concept of fiscal democracy as operationalized by the means of the Steuerle-Roeper Index. It is assumed that the contemporary sociohistorical context comprises a scenario of crisis or decline of democracies, largely explained by the fiscal difficulties faced by the States. The Fiscal Democracy Index is discussed as a promising scientific contribution for the attribution of empirical tangibility to such a reality. However, a difficulty is identified concerning the non-consideration of fundamental rights as condition for the possibility of democratic politics. Finally, an example from the Brazilian constitutional system is presented in order to illustrate the article´s theoretical argument.

Application of machine learning techniques to optical communication systems and networks

This TFM reviews the application of machine learning techniques in optical communication systems and networks. In addition, it studies and compares the characteristics of various machine learning methods, such as: support vector machines, logistic regression, decision trees and random forests, to predict the quality of transmission when using optical circuits in wavelength routed optical communication networks. The models developed in this TFM offer better performance than previous proposals, mainly in terms of computing time, making possible its use in online mode even in highly dynamic networks, in addition to being simpler.El presente TFM realiza una revisión de la aplicación de técnicas de aprendizaje automático en los sistemas y redes de comunicaciones ópticas.

The Solow residual as a black box : attempts at integrating business cycle and growth theories

The intersection between growth and business cycle theory remains a controversial subject in economics. The question posed by this article is, What role did Robert Solow’s “Technical Change and the Aggregate Production Function” (1957) play in recent attempts to integrate business cycle and growth theory? We argue that the “Solow residual” was a resource given to multiple uses, at times rhetorical and symbolic, at times instrumental for theory development, at others a social artifact. On the history of models that bring growth and fluctuation into a single frame, we have focused on the uses and meanings of a particularly prominent object: the Solow residual. The significance of Solow’s 1957 work arose from having stabilized a method and result, the residual as reproducible object, a black box. This object was shown to traffic liberally across doctrinal divides in economics. Once on offer, the black box had a life of its own. Its relation to the original context and to the intentions and beliefs of its originator was severed. So while Denison used the residual in ways that were surely faithful to Solow, the new classicals employed it in ways that seemed counter to Solow’s outlook. While the residual had always remained a problematic result in growth accounting, its borrowing by real business cycle theorists sought to establish it as a definitive representation of technology. Furthermore, in these models it was a short-run and stochastic technology, a novel and surprising interpretationinfo:eu-repo/semantics/publishedVersio

La Reforma procesal penal de Guatemala : del sistema inquisitivo (juicio escrito) al sistema acusatorio (juicio oral) : informe resumido /

Consultable des del TDXTítol obtingut de la portada digitalitzadaLa República de Guatemala, experimentó en el último decenio del siglo veinte, el acontecimiento más importarte de su historia jurídica procesal penal, abandonando el modelo inquisitivo (juicio escrito) y adoptando el sistema acusatorio (juicio oral). La consolidación del Nuevo Sistema, es fundamental para la democracia dentro de un Estado Constitucional de derecho, razón que motivó escribir esta tesis que contiene un análisis de la reforma y una propuesta para la consolidación de la misma, en virtud de que sí bien es cierto ésta principió hace trece años, la implementación que debe garantizar un adecuado funcionamiento del modelo se está realizando actualmente y de él depende el éxito o el fracaso de la reforma. Quienes hemos sido promotores del cambio, debemos demostrar que la correcta aplicación del sistema acusatorio, garantiza que el proceso penal sea el único instrumento constitucional para juzgar la culpabilidad o inocencia del procesado, que debe ser el objetivo de la justicia penal y que inspiró presente trabajo.The Republic of Guatemala has experienced the most important fact of its legal background, in the last decade of the 20th century. It started with a reform in the criminal justice system, which radically changed, the administration of justice, abandoning at the same time, the inquisitorial model (written trial) an adopting the accusatory system (oral trial). The reform of the criminal justice system of Guatemala, formally started the first of July of 1994, with the going into effect of the new law for the reform of the criminal justice system, which in fact is not over yet. This open the door for the reform of the criminal justice system in Latin America, which has to be seen in the global context, as the result of political and economical facts that have changed the sequence of human history, as have disappearance of the Berlin Wall, the end of the Cold War, the democratization of all countries of the area, the ever changing technological advances of the new society of knowledge and international globalization, that brought new criminal forms and social conflicts, which demand a rapid and transparent application of criminal justice, taking into consideration that it is fundamental in the construction of a democratic country, in the constitutional state of law. This is the central motivational factor of this doctoral thesis; basically contains an analysis of the criminal justice reform in Guatemala and a proposal that allows consolidation of this reform; considering the fact that the reform began twenty years ago, the real process that can guarantee an accurate implementation of the model, is currently in place, and everything else depends on the success or failure of the reform. This investigation is structured in six chapters; the first one explains the criminal justice reform in Guatemala and the second, the criminal justice reform in Latin America; the third one refers to the constitutional principles and guarantees of the criminal justice reform in Guatemala; the fourth, considers the main principles of the accusatory system; the fifth concerns the phases of the criminal justice reform in Guatemala and the sixth addresses the proposal for the implementation of the model, which is now been in progress, and the last chapter presents a conclusion, bibliography and a glossary. It is up to those of us, who in one way or another contribute, with the change, to demonstrate that the right application of the accusatory system in Guatemala, guaranties that the reform of criminal justice is the constitutional instrument to prove the guilt or innocence of the accused, and this should be primary objective of the criminal law. It is also the inspiration for this dissertation

Positional trueness of three removable die designs with different root geometries manufactured using stereolithographic 3D printing.

STATEMENT OF PROBLEM Three-dimensional (3D) printed casts are a suitable alternative to dental stone casts. Contemporary dental design computer programs permit designing definitive casts with removable dies with different root geometries and retention mechanisms. Studies on the positional trueness of 3D-printed removable dies with different root geometries are lacking. PURPOSE The purpose of this in vitro study was to investigate the 3D displacements of three 3D-printed removable die designs with different root geometries. MATERIAL AND METHODS The digital file of a dental stone alveolar cast with root-form removable dies (MOD UJ IV Fixed Prosthetics; Ivoclar AG) was used as a reference to create 3 removable die and alveolar cast designs (Root Form, RF; Conical, CON; Cylindric, CYL) with different root geometries in 2 dental design computer programs (DentalCAD 3.1 Rijeka; exocad; GmbH; InLab CAD 22.0; Dentsply Sirona). 3 equidistant Ø1-mm spheres (C, Cervical; M, Middle; O, Occlusal) were designed on the buccal surface of the coronal portion of the removable die to evaluate their displacement. A total of 45 alveolar casts with 45 removable dies were fabricated using a stereolithographic 3D printer (Form 3; Formlabs); each die group consisted of 15 specimens. After fabrication and postprocessing, the specimens were scanned, and their digital files were analyzed in a metrology-grade computer program to evaluate the displacement of the removable dies with respect to the position of the die in the master reference file. Subsequently, the data were analyzed using a 3-way analysis of variance (ANOVA) followed by step-down Bonferroni-corrected pairwise comparisons (α=.05). RESULTS Two statistically significant 2-way interactions were detected between the independent variables, die design and direction (P<.001), and location and direction (P<.001). The post hoc analysis identified significant differences between the displacement values of RF and CYL (P<.001) and RF and the CON (P<.001) designs on the Y axis. The measured displacements were statistically different between the C and O locations on the Y axis (P=.001) and the M and O locations on the Z axis (P=.006). CONCLUSIONS The root geometry of a 3D-printed removable die and alveolar cast can affect seating, and variable degrees of tipping of the removable die can be seen. The seating and congruence of the removable die with the interocclusal space and relationships observed intraorally should be confirmed before adjusting indirect restorations

Manipulation of Light Environment to Produce High-quality Poinsettia Plants

The phytochromes, a family of photoreceptors that maximally absorb red (R) and far-red (FR) light, play an important role in defining the architecture of the plant and consequently its value in the market. In this work, we evaluated the manipulation of light quality as an alternative to the use of plant growth regulators (PGRs) to produce poinsettia plants (Euphorbia pulcherrima Willd. ex Klotzsch) without affecting commercial quality parameters. ‘Freedom Red’ poinsettia plants were cultivated in two light environments characterized by different R/FR ratios in combination with or without one application of PGR. We used a photoselective film that significantly reduced the FR component of the light and a transparent film to obtain high and low R/FR ratios (5.7 and 1.1, respectively). Plants cultivated under a high R/FR ratio were shorter and more compact than those grown under transparent film. Other quality characters like bract and leaf area, dry weight, stem diameter, number of lateral branches, and plant width did not differ significantly between light treatments. Flowering time was slightly delayed in plants grown under a high R/FR ratio compared with those cultivated under the control treatment. Additive effects were detected between light quality and PGR factors indicating that light quality manipulation is an alternative strategy to reduce or to replace the use of PGRs in commercial production systems that usually require several PGR applications.Instituto de FloriculturaFil: Mata, Diego Alejandro.

Information Technology and Sustained Competitive Advantage: A Resource-Based Analysis

This is the published version. Copyright 1995 MIS Quarterly.The concept of IT as a powerful competitive weapon has been strongly emphasized in the literature, yet the sustainability of the competitive advantage provided by IT applications is not well-explained. This work discusses the resource-based theory as a means of analyzing sustainability and develops a model founded on this resource-based view of the firm. This model is then applied to four attributes of IT -- capital requirements, proprietary technology, technical IT skills, and managerial IT skills -- which might be sources of sustained competitive advantage. From this resource-based analysis, we conclude that managerial IT skills is the only one of these attributes that can provide sustainability
