Constituent Assemblies
No full textConstituent assemblies traditionally play a central role in processes of constitution-making, serving as the main actors in drafting new constitutions and the primary sites for deliberating on their content. To perform this role, assemblies have taken various forms and functions, which point to different paradigms and views of their legitimacy and authority. Gradually, as constitu-tion-making has evolved and become more complex, assemblies have been joined by other constituent actors to combine different forms of deliberation and political participation. Against this background, the present chapter sheds light on the evolving character of constituent assemblies as components of a broad set of entities that, together, contribute to elaborate a new constitu-tion.
The analysis is structured as follows. Section I introduces and Section II addresses the nature and role of assemblies, pointing out the main forms they have taken historically and the underlying conceptions of their authority. Section III outlines how democratic constitution-making unfolds within assemblies, as a dynamic that combines mechanisms of representation, deliberation, and participation, and which forms part of a broader process also involving citizens, experts, and other constituent entities. On this basis, Section IV argues that assemblies serve as components of a system of constitution-making, and that, as such, we should address their nature and legitimacy consider-ing how they interact with the other components of that system
On the mirror of the bicentenary
No full textSe analizan condiciones históricas de la conformación de la Región del
Noroeste argentino, con sus particulares características, así como incidencias
del proceso revolucionario de 1810 y algunas repercusiones del mismo en
el futuro de la Región. Se acude para ello al aporte de estudios históricos,
lingüísticos y antropológicos regionales, así como al testimonio de pensadores
comprometidos con su realidad. La población descendiente de los pueblos
originarios aparece sumergida en situaciones de desigualdad y explotación a lo
largo del período recorrido, lo que se expresa a través de obras de luchadores
como M. A. Tanco, J. L. Torres y el grupo Tarja. En la actualidad, y a pesar
de los avances realizados a nivel de Acuerdos y Declaraciones de organismos
internacionales, la demanda de su legítimo y efectivo reconocimiento es una
deuda pendiente, lo que conlleva connotaciones éticas que cuestionan las
bases de nuestro sistema democrático.The author analyzes the historical conditions of Argentina’s Northwest during
its conformation, and its particular characteristics through the revolutionary
process of 1810 and some of its repercussions in the future. Historical,
linguistic and regional anthropological studies are used in this analysis, as
well as the testimony of the engaged humanists (thinkers, philosophers) of
its time. The local native population appears in situations of inequality and
exploitation during this long period, as seen through the works of leaders
such as M. A. Tanco, J. L. Torres and the Tarja group. Currently, in spite of the
progress achieved at the level of Agreements and Declarations by international
organizations, their legitimate demand and actual recognition is a pending
debt, which carries ethical connotations that question the basic principles
of our democracy.Fil: Rubinelli, María Luisa.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Performance of annealed hybride silicon heterojunctions: a numerical computer study
Get PDFThe performance of the standard hydrogenated amorphous silicon carbon–crystalline silicon solar cell is extensively compared with the performance of a hybrid structure subjected to a high-temperature annealing processing. Our analysis indicates that high-temperature-annealed heterojunctions show more robustness in the presence of energy offsets and defective amorphous-crystalline interfaces. Annealed hybrid cells are also less vulnerable to the negative impact of amorphous silicon carbon doped layers with poor electrical properties. Furthermore, annealed structures have the potential to generate higher efficiencies than conventional heterojunctions regardless of the wafer quality. The presence of boron at the amorphous-crystalline interface and in the wafer front region plays an important role in annealed hybrid structures that are made with low-quality wafers or where there is a highly defective amorphous-crystalline interface. In this scenario, a linear boron profile in the wafer front region is more appropriate, for which there is an optimum thickness. For low defect amorphous-crystalline interfaces and high-quality wafers, a boron exponential profile is more appropriate when boron creates additional defects in the front region of the wafer. The shape of the boron profile becomes less relevant when the boron does not add additional defects to the front region of high-quality wafers and when the amorphous-crystalline interface is low defect or defect-free.Fil: Rubinelli, Francisco Alberto.

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

No full textPressure overload leads to coronary plaque formation, progression, and myocardial events in ApoE–/– mice
No full textHypercholesterolemia and hypertension are two major risk factors for coronary artery diseases, which remain the major cause of mortality in the industrialized world. Current animal models of atherosclerosis do not recapitulate coronary plaque disruption, thrombosis, and myocardial infarction occurring in humans. Recently, we demonstrated that exposure of the heart to high pressure, by transverse aortic constriction (TAC), induced coronary lesions in ApoE–/– mice on chow diet. The aim of this study was to characterize the magnitude and location of coronary lesions in ApoE–/– mice after TAC and to assess the susceptibility of coronary plaque to disruption, leading to myocardial events. Here, we describe a reliable pathological condition in mice characterized by the development of coronary lesions and its progression, leading to myocardial infarction; this model better recapitulates human disease. Following TAC surgery, about 90% of ApoE–/– mice developed coronary lesions, especially in the left anterior descending artery, with 59% of the mice manifesting a different magnitude of LAD stenosis. Myocardial events, identified in 74% of the mice, were mainly due to coronary plaque thrombosis and occlusion. That TAC-induced development and progression of coronary lesions in ApoE–/– mice, leading to myocardial events, represents a potentially novel and important tool to investigate the development of coronary lesions and its sequelae in a setting that better resemble human conditions
