Sphaerids have adopted a variety of life strategies that have allowed them to show a cosmopolitan distribution. Among these strategies, those related to reproduction, such as sexuality (hermaphroditism), offspring incubation, fertility, number of generations per year, times an individual reproduces during its lifespan, among others, have been decisive with regard to its permanence in time and space, and to colonize and maintain populations in permanent or temporary freshwater bodies. The aim of the current study is to compare reproductive traits of 2 Musculium argentinum populations inhabiting different environments (stream and lake) to determine the potential influence of the environment on reproduction of these populations. During 1 y (October 2006 to 2007) monthly samples were taken at 2 study sites: Lautaro stream (38032' S, 72[degrees]27' W) and La Poza, Villarrica Lake (39[degrees]16'27" S, 71[degrees]58'54" W). Sixty specimens were collected monthly from each population. Valve length of each specimen of the sample was registered to determine the size structure of each population. Fifty animals of known valve length were dissected to determine presence and number of brooding sacs in the inner hemibranches, number of embryos in each sac...

Português
Proponemos una metodología para describir la estructura y el funcionamiento del texto "sentencia penal chilena" y evaluar la calidad de su argumentación. La importancia de estos procesos radica en que la sentencia es un caso paradigmático del modo en que las sociedades construyen lo bueno y lo malo. En virtud de la especificidad del género y del registro lingüístico del texto en estudio, integramos elementos de pragma-dialéctica, de lingüística sistémico funcional y de Modified Wigmorean Analysis para suplir las desventajas individuales de cada metodología y optimizar sus ventajas. Se revisa someramente el aparato crítico que sustenta cada una de las estrategias de análisis, luego, a través del estudio de un fragmento de una sentencia real, demostramos la factibilidad de la integración y concluimos revisando la posibilidad de usar esta propuesta en comparaciones intertextuales e interdiscursivas.; We propose a methodology to describe the structure and operation of the text "Chilean criminal sentence" and to evaluate the quality of its argumentation. The relevance of these procedures lies in the sentence is a paradigmatic case of the way in which societies build good and bad things.

The chelate ligands 11-R-dipyrido[3,2-a:2′,3′-c]phenazine, dppz-R (R = NH2, CH3, H, COOH, NO2) and the Re(dppz-R)(CO)3Cl (R = NH2, COOH, NO2) complexes were synthesized and characterized by conventional techniques. The influence of the donor and acceptor properties of the R substituents on the ligand properties were studied by spectroscopic techniques such as 1H-NMR and UV-Vis. Theoretical calculations were also achieved, mainly to interpret and understand the experimental spectra.

Português
El número IV de la Revista CREA constituye un nuevo esfuerzo de la Escuela de Derecho de la Universidad Católica de Temuco en lo que refiere a la investigación y difusión de la resolución alternativa de conflictos. En esta oportunidad se busca abrir el debate hacia la circunstancia de que en las últimas décadas ha habido en el mundo y recientemente en Chile, un surgimiento (o un re-surgimiento) en distintas áreas de la vida civil y política, de una serie de prácticas de justicia caracterizadas por plantearse como 'alternativas' al sistema de justicia tradicional o formal. Tales prácticas han recibido distintas denonminaciones, tales como: resolución alternativa de disputas, resolución pacífica de controversias, justicia informal y justicia restaurativa, entre otras. Todas ellas planlean diversas interrogante5 en torno al rol del Estado, la promoción y protección de los intereses y derechos de las personas que participan en estos procedimientos, y las particulares nociones de justicia que subyacen a estas prácticas, por mencionar tan sólo a algunas de dichas interrogantes.

‣ Entre la virtud y la fortuna. Portales en los ojos de Maquiavelo

Tipo: Libro
Português
Este libro tiene por fin esbozar una nueva interpretación sobre la figura de Portales en la historia política chilena, a través del análisis de su participación política en la primera mitad del Chile decimonónico. Algunos sectores de la historiografía chilena le han atribuido al Ministro ser el responsable del establecimiento de un orden denominado como el “Estado en Forma” o el “Régimen Portaliano”. Este estudio no pretende entrar en la discusión si Portales fue un “gran estadista” o si ha sido “una falsificación histórica”, ya que son discusiones historiográficas que responden a miradas omnímodas, lo cual no es nuestra intención. La mirada que hemos de desarrollar en este análisis pretende interpretar un aspecto en el proceso de formación de la república en Chile, utilizando como protagonista a Portales, a partir de la polaridad que existe entre los conceptos de fortuna y virtud, expresada en la obra de Maquiavelo El Príncipe, y cuyo juego dialéctico animaría el ejercicio del poder. La fortuna aquí es definida como la incertidumbre generada por la innovación política que quiebra las costumbres o tradiciones legitimantes del orden precedente, escenario que solo puede ser dominado por las virtudes del ‘príncipe'. En un estado político incierto...

‣ Nuevos realismos y sociedades complejas

Português
Las relaciones entre ciencia y sociedades complejas conforman el trasfondo de este texto, en el cual se reflexiona sobre el diálogo, tensión o escisión entre la ciencia entendida ya como dominio de lo público, como bien público y la sociedad civil en la que conviven grupos e individuos con identidades y concepciones de vida diversas e incluso confrontadas. Para ello, se describen ciertos hitos que dan cuenta de los cambios que tanto al interior de la epistemología, filosofia y teon'a social como en la vida se han ido gestando en la modernidad tardía, los cuales al menos potencialmente abocan los esfuerzos tanto en el plano teórico como en el social a trabajar en pos del diálogo. Sin embargo, pareciera, que existiendo la oportunidad de establecer una relación deliberativa entre ciencia y sociedad, ésta por el momento no se da.

‣ La mediación en la justicia penal juvenil

Português
En el marco del nuevo paradigma de la responsabilidad penal juvenil los servicios de administración de justicia deben adecuar sus procedimientos y herramientas a fin de permitir que las medidas socioeducativas cumplan con su finalidad específica. Basados en los conceptos de justicia restaurativa, con el aporte multidisciplinario, una fuerte raigambre en los derechos humanos fundamentales y la participación comunitaria, los modelos de métodos alternativos de resolución de controversias, como la mediación, vienen a ocupar un lugar privilegiado para el abordaje de la problemática de los jóvenes a quienes se les atribuya la comisión de actos que encuadren en infracciones a la norma penal. El sistema penal tradicional además de ser un reproductor de la violencia a través de las respuestas coercitivas y la estigmatización, no brinda el espacio para una positiva responsabilización, la reparación del daño y la reactivación de los vínculos sociales. Más que una salida alternativa al procedimiento judicial se trata de una verdadera práctica transformadora tendiente a desarrollar el potencial de cambio en los jóvenes, para que puedan, a través de la participación en un espacio de diálogo, ser protagonistas de la construcción de su personalidad autónoma.; Within the frame of the new paradigm of juvenile criminal responsibility...

The aim of this work is to examine the pentafactorial validity of the AF5 Self-Concept Questionnaire in Spanish and Chilean young adults. From the responses of a total of 4, 383 young adults aged 17 to 22 years (1, 918 Spanish, 44%, and 2, 465 Chilean, 56%) it was analyzed the reliability of the instrument, the compared validity of the 5 oblique factor model proposed by the authors versus the unifactorial and the orthogonal alternative models, and was studied the invariance of one Chilean sample. The results of confirmatory factor analyses supported the authors' pentafactorial model. The multi-group factorial invariance showed that Chilean sample of the AF5 does not change neither the Spanish factor weights, nor the variances and covariances of the factors, or the error variances of items. Finally, the internal consistency of the five scales was good in the samples of both countries.

‣ The invention of the myth of Diego Portales: Death and funeral rites in the chilean republican tradition

Português
Diego Portales has become a true legend of Chilean political history, a controversial figure who has prompted very differentki nds of interpretation. The aim of this article is to analyze the origin of his political myth. We will study the final phase of the minister's political activities in 1837 from the perspective of Machiavelli's The Prince. By means of the Florentine philosopher's modern political theory, we may explain the circumstances which surrounded the death of Portales. A look at Portales's funeral reveals that it responded to a need to create a republican tradition at the time of the birth of the Hispano-American nations.

‣ The mediated reading of child literature as a tool for the basic emotional literacy

Fonte: Universidade Católica de Temuco Publicador: Universidade Católica de Temuco
Tipo: Artículo de Revista
Português
The reading of literature during childhood allows the child reader to explore the world of fiction in which different realities are characterized by a series of social interactions and, therefore, by emotional processes. In the present article, the authors highlight the way in which the reading of child literature contributes to the emotional and social development of the children through a process named "mediated reading". During this process, the adult reader operates as a mediator of the emotional "fictional" experience of the characters of the narration, of the tale and of those real processes that characterize the context and the vital experience of the children. Furthermore, the narration is not intended to draw the children into the "teaching" of a specific emotion. In this way, the mediated reading of literature during childhood operates as a tool of emotional literacy, a process that allows the recognition of the own and the other's emotions as a way of developing empathy and pro-social behavior. The article finishes by discussing the scope of the process of mediated reading of child literature as a tool that promotes the schooling inclusion and allows the interaction between the cognitive and affective aspects in the formal education.

‣ A flight without organs? (Ego, orality and writing in El obsceno pájaro de la noche)

Tipo: Artículo de Revista
Português
El obsceno pájaro de la noche (The obscene night bird), in line to other great novels of Latin American Boom, understands that the omniscient author, like the ego, is a small tirant, though not a body tirant, but a tirant of narration itself. This novel tries to get free from that god through a series of devices. Among these devices we posit the co-existence of two basic narrators: one of them, resposible for the novel's pre-text, is closer to oral discourse, and the other one, responsible for the text proper, is closer to omniscience, and in regard to discourse, works within the framework of literacy. The theory that allows an analysis like this is the one that studies bodies that lack an ego, schizophrenia, and hence we try to join some schizoanalysis propositions and some of narratology and text analysis in order to study the narrative stratum of El obsceno pájaro de la noche. It is important to point out that for our study we have used Donoso's manuscripts, kept at the libraries of The Univesity of Iowa and Princeton University. © 2011 Universidad de Concepción.

Phytophthora infestans Mont. de Bary, causes one of the most important diseases in potato fSolanum tuberosum L.). Since the last decade, repeated years of 'blight' affecting many varieties and cultivars have been observed in Chile. This has led to the validation of different early warning systems, the Blitecast model being one of the most efficient. The aim of this study was to assess the response of native varieties and com mercial cultivars of potato to natural infections of late blight, managed on the basis of early warning system. During the 2006/2007 season, a study was conducted with a split plot de sign with four replications and factorial arrangement of treat ments, with seven genotypes and two early warning systems as study factors. Native varieties used were Michuñe azul and Clavela and cultivars Desirée, Yagana, Karu, Pukará and Car dinal. The early warning systems assessed were the Blitecast model and a witness without chemicals, as a decision tool to apply chemical control. No interaction effects were observed in the study (p>0.05). The leaf damage and area under the curve of disease progress (AUDPC) were significantly lower (p<0.05) in cv. Cardinal than cv. Desirée, in coincidence with the offi cial description of both cultivars. The AUDPC ranked Michuñe azul (119.39) and Clavela (120.54) as moderately resistant vari eties. The main effects of an early warning system reduced sig nificantly (p<0.0001) the AUDPC and leaf damage of the crop. The latter was reduced by 64.5% when compared with the system without early warning.

‣ Edips: An easy to deploy indoor positioning system to support loosely coupled mobile work

Português
Loosely coupled mobile work is characterized by nomadic workers collaborating in sporadically and ondemand ways. Supporting nomadic workers' interactions requires knowing the location of the potential collaborator; therefore, indoor/outdoor positioning systems play a key role. Locating persons in outdoor environments is well addressed by Global Positioning Systems (GPS); however, for the indoor scenario, the solution is not so clear. Although several proposals for indoor positioning have been reported in the literature, most of them demand important setup efforts. This article presents the Easy to Deploy Indoor Positioning System (EDIPS), a WiFi-based system able to support the typical location requirements involved in loosely coupled mobile work. EDIPS is aimed for fast deployment and real-time operations rather than for location accuracy. The system was preliminary evaluated as a support for locating medical interns' in a simulated hospital. The results obtained indicate the solution is able to locate nomadic workers in an indoor scenario, with enough accuracy to support loosely coupled mobile work, while requiring minimal setup effort. © Springer-Verlag London Limited 2011.

‣ Detection of gene expressions in microarrays by applying iteratively elastic neural net

Português
DNA analysis by microarrays is a powerful tool that allows replication of the RNA of hundreds of thousands of genes at the same time, generating a large amount of data in multidimensional space that must be analyzed using informatics tools. Various clustering techniques have been applied to analyze the microarrays, but they do not offer a systematic form of analysis. This paper proposes the use of Gorban's Elastic Neural Net in an iterative way to find patterns of expressed genes. The new method proposed (Iterative Elastic Neural Net, IENN) has been evaluated with up-regulated genes of the Escherichia Coli bacterium and is compared with the SelfOrganizing Maps (SOM) technique frequently used in this kind of analysis. The results show that the proposed method finds 86.7% of the up-regulated genes, compared to 65.2% of genes found by the SOM. A comparative analysis of Receiver Operating Characteristic (ROC) with SOM shows that the proposed method is 11.5% more effective.

Analysis of the applicability of environmental certification standards (ISO 14001) in companies in Chile's IX Region by carrying out an environmental survey and identifying the factors, which support or limit the application of the present laws is presented. Variables evaluated included legal aspects, training, and environmental performance among others. The results demonstrated that companies are gradually incorporating environmental considerations into their management processes, especially under the requirements of Law 19. 300 on General Environmental Fundamentals passed in 1994. It is shown that additional factors such as environmental training and familiarity with the environmental standard, facilitate the implementation of environmental legislation. Limitations on this implementation include lack of economic resources and dissatisfaction with the functioning of environmental legislation in Chile. It is concluded that companies in the IX Araucanía Region have few limitations for implementing the environmental management systems ISO 14001.

Pastures in the south of Chile have been shown to be selenium deficient, and as selenium is a component of deiodinase type 1, which is necessary for the synthesis of triiodothyronine (T3) at peripheral levels, the effect of selenium deficiency on the blood concentration of theses hormones in cows was studied. Twelve pregnant Friesian cows were randomly allocated into two homogeneous groups of six animals each-selenium supplemented and selenium deficient. The selenium deficient diet consisted of 11.5 kg of hay, 500 g of soya bran, 150 g of mineral mix (without selenium), 500 g of fat for animal feeding, and was given from day 15 of lactation until the end of the study. A commercial concentrate (Cosetan) and urea was also given according to lactation requirements (up to 5 kg and up to 120 g, respectively). The selenium content was 0.05 ppm of dry matter (equivalent to 18% of the daily requirements). The supplemented group was injected subcutaneously with 1 mg Se/kg, using the commercial product Deposel (1 ml/50kg). Blood samples were obtained by coccygeous vein venepuncture before supplementation (prepartum basal values) and thereafter every 15 days. GSH-Px activity in plasma was measured using a HITACHI 4020 spectrophotometer. Serum T3 and thyroxine (T4) concentrations were measured by electrochemiluminiscence. ANOVA...

Objective: To identify and understand factors associated to pregnancy in adolescents under the perspective of the never pregnant adolescent. Methods: Qualitative study undergone on women 15 to 19 years of age. School based sample of women were drawn from 2 schools chosen due to their high pregnancy rate. Four focus groups were created and each one was composed by 14 eligible women. Factors associated to individuals, to family, and to social environment were studied. Triangulation was performed during the study conduction and data analysis. Analysis was done by using ATLAS-ti 4.1. Results: Factors which appear to be favouring pregnancy at the individuals were: "romantic love", no use of contraceptives, low self esteem, male irresponsibility, lack of knowledge in sexuality. At the family level, the factors are: the permit's restriction and paternal negligence. Factors which help in avoiding pregnancy in adolescents at the individual level are: subject's reflexive capacity and project of life. At the family level, protective family and clearly defined limits are the ones which help preventing pregnancy. Social punishment is the main social factor associated. Conclusions: The view of the never pregnant adolescent and the multilevel model used in the focus group will allow decision makers to design strategies at the subject...
