Envejecimiento de la población y sistemas de pensiones en América Latina

Este artículo examina el papel que desempeña el envejecimiento demográfico en la evolución de mediano a largo plazo de los sistemas de pensiones en América Latina y el Caribe. Está organizado en seis secciones. Luego de la sección introductoria, la sección II entrega información sobre las tendencias del envejecimiento y de los sistemas de pensiones en los países latinoamericanos, con algunas referencias al contexto internacional. La sección III presenta los indicadores, datos y métodos de análisis, y examina el efecto de las estructuras de población envejecidas y de la creciente longevidad en las variables de los sistemas: el gasto en pensiones, el balance financiero, las obligaciones pensionales y la rentabilidad implícita; también hace un análisis crítico de los criterios que suelen utilizarse para evaluar la sustentabilidad de los sistemas de reparto. Luego, la sección IV introduce de manera más sistemática el concepto y los indicadores de la deuda personal implícita, entrega estimaciones de la magnitud de las obligaciones pensionales que deben hacerse explícitas al cambiar a un régimen de capitalización, y analiza los efectos de la estructura etaria y de la mortalidad adulta en los países latinoamericanos. La sección V examina brevemente los costos fiscales de transición que es preciso afrontar cuando se aplica este tipo de reforma, y por último, la sección VI proporciona un resumen y conclusiones.

Le poids de la notion Tesniérienne de centralité du verbe dans les analyses linguistiques

This paper examines the historical role that Tesnière’s theory on the centrality of the verb exerted on some theoretical branches that study the way utterances are built in language. The main goal of this paper is to evaluate the impact that such a proposal had in changing the view of the clause being purely logical (a proposition) or purely syntactic (abstractly equated) to a view that embodies semantics and pragmatics to the syntactic organization of the utterance. A close examination of research dedicated to the grammatical and lexicographic description of Portuguese helps to illustrate the here proposed assessment and contributes to support the claim of the influence of Tesnière on current linguistic analyses.

Abordaje conservador y mínimamente invasivo de la hipomineralización molar-incisivo (HMI) - Relato de casos clínicos

Molar-Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that affects one to four permanent first molars, with or without involvement of permanent incisors. Enamel defects may produce many symptoms that have physical, social and psychological effects and influence day-to-day living or quality of life. The available treatment modalities for teeth with MIH are extensive, ranging from prevention, restoration, to extraction. Factors such as age, patient expectations, severity of the lesion and materials should be considered in the treatment of the patient with MIH. Restoration with composite resin is an alternative choice for posterior and anterior MIH defective teeth and its use has been show acceptable results. This article describes two clinical cases involving pediatric patients with MIH whose procedure of cavity preparation was based on the use of CVD ultrasound diamond tips and restored using composite resin obtaining favorable esthetics results after a 1 year follow-up.

Crystallization conditions and controls on trace element residence in the main minerals from the Pedra Branca Syenite, Brazil: An electron microprobe and LA-ICPMS study

Major and trace-element microanalyses of the main minerals from the 610 Ma Pedra Branca Syenite, southeast Brazil, allow inferences on intensive parameters of magmatic crystallization and on the partition of trace-elements among these minerals, with important implications for the petrogenetic evolution of the pluton. Two main syenite types make up the pluton, a quartz-free syenite with tabular alkali feldspar (laminated silica-saturated syenite, LSS, with Na-rich augite + phlogopite + hematite + magnetite + titanite + apatite) and a quartz-bearing syenite (laminated silica-oversaturated syenite, LSO, with scarce corroded plagioclase plus diopside + biotite +/- hornblende + ilmenite magnetite +/- titanite + apatite). Both types share a remarkable enrichment in incompatible elements as K, Ba, Sr, P and LREE. Apatite saturation temperatures of similar to 1060-1090 degrees C are the best estimates of liquidus, whereas the pressure of emplacement, based on Al-in-hornblende barometry, is estimated as 3.3 to 4.8 khan Although both units crystallized under oxidizing conditions, oxygen fugacity was probably higher in LSS, as shown by higher mg# of the mafic minerals and higher hematite contents in Hem-Ilm(ss). In contrast with the Ca-bearing alkali-feldspar from LSO, which hosts most of the whole-rock Sr and Pb, virtually Ca-free alkali-feldspar from LSS hosts similar to 50% of whole-rock Sr and similar to 80% of Pb, the remainder of these elements being shared by apatite, pyroxene and titanite. This contrast reflects a strong crystal-chemical control, whereby a higher proportion of an element with similar ratio and charge (Ca2+) enhances the residence of Sr and Pb in the M-site of alkali feldspar. The more alkaline character of the LSS magma is inferred to have inhibited zircon saturation; Zr + Hf remained in solution until late in the crystallization, and were mostly accommodated in the structure of Ca-Na pyroxene and titanite, which are one order of magnitude richer in these elements compared to the same minerals in LSO, where most of Zr and Hf are inferred to reside in zircon. The REE, Th and U reside mostly in titanite and apatite; D(REE)Tit/Ap raises steadily from 1 to 6 from La to Tb then remains constant up to Lu in the LSO sample; these values are about half as much in the LSS sample, where lower contents of incompatible elements in titanite are attributed to its greater modal abundance and earlier crystallization.

Children with Type 1 Diabetes Mellitus and their friends: the influence of this interaction in the management of the disease

Friends' support is a key element in the management of Type 1 Diabetes Mellitus. This study describes the influence of friends on the lives of children with Diabetes Mellitus and its implications for managing the disease. Empirical data were collected through semi-structured interviews, supported with the use of puppets, with 19 children aged between seven and 12 years old. The qualitative analysis of the testimonies allowed understanding the phenomenon from two perspectives: the attitude of friends towards the child, positively or negatively affecting the disease's management, and the attitude of the child toward friends. The knowledge of those involved and the interaction between the children with DM1 and their friends impacts the management of the disease. Understanding the implications of these interactions contributes to the delivery of qualified nursing care to this population.
