La construcción de la figura legendaria de Alfonso XI en el “Poema de Alfonso Onceno” y la “Gran Crónica de Alfonso XI”

El artículo intenta estudiar, tanto en el Poema de Alfonso Onceno como en la Gran Crónica de Alfonso XI, cómo el dispositivo discursivo legendario se utiliza con un fin propagandístico de la figura del rey, pues se destina principalmente a exaltarlo no sólo en cuanto a su triunfo en la sumisión de los nobles levantiscos sino también a su éxito en las campañas militares contra los musulmanes.

The pottery from A and C-Group tombs at Serra West in the Museum of Natural History, La Plata

Abstract: The Museum of Natural History, La Plata, Argentina, houses a ceramic collection of the A-Group and C-Group cultures from Nubian tombs at Serra West (AA and ACS cemeteries), on the west bank of the Nile in Lower Nubia. It has been originated from the division after the excavations made by the Franco-Argentine Archaeological Expedition in Sudan between 1961 and 1963, as part of the UNESCO campaigns to save the Nubian monuments.

La construcción del mensaje personalizado en las campañas electorales

La identificación del candidato con un producto comercial ha dado origen a una resistencia de parte de los partidos de marcada tradición ideológica y de variados ambientes culturales que ven en, lo que se ha denominado, la comercialización de la política y de las campañas un peligro para el proceso democrático. Encontramos que más allá de identificar a un candidato con un jabón, las técnicas utilizadas para elaborar los mensajes políticos no pueden ser minusvaloradas porque se utilicen en el campo comercial, sino que lo importante es establecer y respetar los contenidos de cada ámbito. Sin zanjar la cuestión, sobre el impacto que los medios de comunicación tienen en la vida democrática, este estudio intenta señalar que la personalización es parte esencial del proceso de comunicación política que genera cualquier campaña electoral. Para ello describe los factores que intervienen en la construcción del mensaje personalizado. Estudio este que debe abordarse teniendo en cuenta que el nuevo formato, a través del cual se trasmiten los mensajes políticos, es mediático y esencialmente audiovisual.

A associação de questões aos partidos políticos e as eleições presidenciais no Brasil

Uma questão central em uma democracia é descobrir o que leva os eleitores a decidir por um candidato em vez de outro. Em democracias já estabelecidas, fatores como a identificação partidária e o elevado nível de informações disponíveis durante a campanha diminuem a possibilidade de persuasão dos eleitores. Já nas novas democracias, como é o caso do Brasil, acredita-se que a identificação partidária é baixa e, por conta disso, os eleitores têm dificuldades em associar determinadas questões aos partidos políticos. No presente artigo busca-se verificar se há indícios da associação de questões aos partidos políticos durante as campanhas presidenciais no Brasil de 2002 a 2010

Emendas individuais ao orçamento da união dos deputados federais do Estado da Paraíba da 53ª legislatura : uso eleitoral das emendas individuais ao orçamento

O presente trabalho consiste na análise das emendas individuais ao Orçamento da União dos deputados federais do Estado da Paraíba, na 53ª legislatura, para verificar se elas atendem as prioridades sociais da população, baseando-se no Índice de Desenvolvimento Humano onde identificamos o índice de pobreza elevado, ou se elas são destinadas mais com intuito de lograr êxito nas campanhas eleitorais. São analisadas também quais as principais áreas que as emendas são destinadas e se há ou não privilégios em sua destinação, de acordo com o colegiado eleitoral dos parlamentares. Para tanto, descrevemos um pouco sobre o Estado e posteriormente apresentamos uma visão geral do orçamento. Conclui-se que fica comprovado o quanto é presente a oligarquia na política do Estado e, por isso, revela as ações paroquialistas dos deputados que utilizam as emendas orçamentárias individuais para levar benefícios para seus redutos eleitorais, bem como para localidades que possam lhe prospectar uma votação significativa e assim garantir sua reeleição ou eleição dos seus indicados.

Parámetros de contaminación y normativa en colectores urbanos

[ES] La contaminación por aguas residuales urbanas es uno de los problemas de mayor importancia para mantener un nivel de calidad aceptable del agua, debido al número elevado de fuentes, a la participación de la contaminación difusa y a la elevada concentración de materia orgánica. La normativa legal plantea unos límites eflDidos, pero no se han realizado campañas de seguimiento de forma suficiente para su comprobación, particularmente en estiaje. El problema se complica por la diversidad apreciable que se observa y la necesidad de dar significación estadística a las conclusiones. En este trabajo, junto a un análisis del seguimiento de una docena de parámetros en diversos colectores de aguas residuales de una zona urbana, se pretende eparar/advertir la dificultad que presenta cada uno de eUos para el cumplimiento legal en relación con las caraterísticas de las fuentes de procedencia y la situación estacional durante el análisis. Además, se pretende buscar de una forma incial las posibles relaciones que se presentan entre las variaciones simultáneas de dichos parámetros. Algunos de eUos muestran una relación clara por lo que podría establecerse alguna dependencia funcional, mientras que en otros casos el problema resulta excesivamente complejo por la necesidad de disponer de más información para Uegar a establecer alguna relación.

Influence of Training Set Selection in Artificial Neural Network-Based Propagation Path Loss Predictions

This paper analyzes the use of artificial neural networks (ANNs) for predicting the received power/path loss in both outdoor and indoor links. The approach followed has been a combined use of ANNs and ray-tracing, the latter allowing the identification and parameterization of the so-called dominant path. A complete description of the process for creating and training an ANN-based model is presented with special emphasis on the training process. More specifically, we will be discussing various techniques to arrive at valid predictions focusing on an optimum selection of the training set. A quantitative analysis based on results from two narrowband measurement campaigns, one outdoors and the other indoors, is also presented.

The cast net fishery, Kainji Lake, Nigeria 1970-1997

This study was carried out to establish trends in the cast net fishery of Kainji Lake, Nigeria. The cast net fishery was second in importance to the gillnet fishery in the early years after impoundment of the lake and still continues to be an important component of the fishery. Some of the economically important species such as Citharinus spp, Tilapia spp, Labeo spp, Alestes spp and Synodontis spp are exploited by cast nets. The study has not revealed any drastic perturbation in the species diversity, catch composition, and any real ecosystem overfishing. On the other hand, both the catfish, Auchenoglanis spp and the predator Hydrocynus spp appear to have increased in the catch in recent years. Never-the-less there is a decline in the mean weight of the major exploited fish species due to the capture of under sized fishes without allowing them to grow to 'legally' marketable sizes. The use of small meshed cast net and also fishing in the shallow waters of the lake can give rise to this situation. Thus, there are signs of growth overfishing in the fish stocks. It must also be acknowledged that the situation is complicated by the fact that in a multi-gear fishery as on Kainji Lake, the cast net fishery could not be managed in isolation without due regard to the other competing gears. The catch per unit of effort (CPUE) has declined in the cast net fishery possibly due to the increase in effort by the major fishing gears over the years. The ongoing extension campaigns by the KLFPP appears to be having the desired effect, as there was reduction in the number of the major fishing gears on the Lake in 1997. It can be anticipated that if this trend continues, the CPUE will recover in the long run. Yields observed from the mesh selectivity study revealed that for major species in the cast net fishery, both by number and weight, were maximal at 2.5 inch mesh, which contrasts with the fact that current minimum allowable mesh in the Fisheries Edict for the Lake is 2.0 inch. The adoption of 2.5 inch as the minimum allowable mesh in the cast net fishery is recommended to be included in future revision of existing regulations. It is also recommended that for this control to have a desired effect, the casting of the net from the shore should be prohibited so as to reduce the incidence of juvenile mortality in the nursery areas.

Legal dimensions of the Chinese experience in Los Angeles, 1860-1880

On October 24, 1871, a massacre of eighteen Chinese in Los Angeles brought the small southern California settlement into the national spotlight. Within a few days, news of this “night of horrors” was reported in newspapers across the country. This massacre has been cited in Asian American narratives as the first documented outbreak of ethnic violence against a Chinese community in the United States. This is ironic because Los Angeles’ small population has generally placed it on the periphery in historical studies of the California anti-Chinese movement. Because the massacre predated Los Angeles’ organized Chinese exclusion movements of the late 1870s, it has often been erroneously dismissed as an aberration in the history of the city.

The violence of 1871 was an outburst highlighting existing community tensions that would become part of public debate by decade’s close. The purpose of this study is to insert the massacre into a broader context of anti-Chinese sentiments, legal discrimination, and dehumanization in nineteenth century Los Angeles. While a second incident of widespread anti-Chinese violence never occurred, brutal attacks directed at Chinese small businessmen and others highlighted continued community conflict. Similarly, economic rivalries and concerns over Chinese prostitution that underlay the 1871 massacre were manifest in later campaigns of economic discrimination and vice suppression that sought to minimize Chinese influence within municipal limits. An analysis of the massacre in terms of anti-Chinese legal, social and economic strategies in nineteenth-century Los Angeles will elucidate these important continuities.

Understanding planet formation through high precision photometry and spectroscopy

From studies of protoplanetary disks to extrasolar planets and planetary debris, we aim to understand the full evolution of a planetary system. Observational constraints from ground- and space-based instrumentation allows us to measure the properties of objects near and far and are central to developing this understanding. We present here three observational campaigns that, when combined with theoretical models, reveal characteristics of different stages and remnants of planet formation. The Kuiper Belt provides evidence of chemical and dynamical activity that reveals clues to its primordial environment and subsequent evolution. Large samples of this population can only be assembled at optical wavelengths, with thermal measurements at infrared and sub-mm wavelengths currently available for only the largest and closest bodies. We measure the size and shape of one particular object precisely here, in hopes of better understanding its unique dynamical history and layered composition.

Molecular organic chemistry is one of the most fundamental and widespread facets of the universe, and plays a key role in planet formation. A host of carbon-containing molecules vibrationally emit in the near-infrared when excited by warm gas, T~1000 K. The NIRSPEC instrument at the W.M. Keck Observatory is uniquely configured to study large ranges of this wavelength region at high spectral resolution. Using this facility we present studies of warm CO gas in protoplanetary disks, with a new code for precise excitation modeling. A parameterized suite of models demonstrates the abilities of the code and matches observational constraints such as line strength and shape. We use the models to probe various disk parameters as well, which are easily extensible to others with known disk emission spectra such as water, carbon dioxide, acetylene, and hydrogen cyanide.

Lastly, the existence of molecules in extrasolar planets can also be studied with NIRSPEC and reveals a great deal about the evolution of the protoplanetary gas. The species we observe in protoplanetary disks are also often present in exoplanet atmospheres, and are abundant in Earth's atmosphere as well. Thus, a sophisticated telluric removal code is necessary to analyze these high dynamic range, high-resolution spectra. We present observations of a hot Jupiter, revealing water in its atmosphere and demonstrating a new technique for exoplanet mass determination and atmospheric characterization. We will also be applying this atmospheric removal code to the aforementioned disk observations, to improve our data analysis and probe less abundant species. Guiding models using observations is the only way to develop an accurate understanding of the timescales and processes involved. The futures of the modeling and of the observations are bright, and the end goal of realizing a unified model of planet formation will require both theory and data, from a diverse collection of sources.

Violence in the Medieval Church before the First Crusade

The attitude of the medieval church towards violence before the First Crusade in 1095 underwent a significant institutional evolution, from the peaceful tradition of the New Testament and the Roman persecution, through the prelate-led military campaigns of the Carolingian period and the Peace of God era. It would be superficially easy to characterize this transformation as the pragmatic and entirely secular response of a growing power to the changing world. However, such a simplification does not fully do justice to the underlying theology. While church leaders from the 5th Century to the 11th had vastly different motivations and circumstances under which to develop their responses to a variety of violent activities, the teachings of Augustine of Hippo provided a unifying theme. Augustine’s just war theology, in establishing which conflicts are acceptable in the eyes of God, focused on determining whether a proper causa belli or basis for war exists, and then whether a legitimate authority declares and leads the war. Augustine masterfully integrated aspects of the Old and New Testaments to create a lasting and compelling case for his definition of justified violence. Although at different times and places his theology has been used to support a variety of different attitudes, the profound influence of his work on the medieval church’s evolving position on violence is clear.

Impacto da campanha de vacinação para influenza em uma empresa

A influenza é uma das doenças respiratórias agudas mais prevalentes e importante causa de absenteísmo e presenteísmo. Entretanto, a eficácia vacinal para influenza pode alcançar 80% quando há elevada correspondência entre cepas vacinais e circulantes. Por este motivo, a empresa há anos promove campanha de vacinação, contudo, sem estimar sua efetividade (eficácia na redução da carga da doença) e o impacto econômico (produtividade) para o aprimoramento de sua política de saúde ocupacional. Considerou-se que a efetividade da campanha seria determinada pela eficácia vacinal previamente demonstrada em estudos randomizados, pelo grau de acurácia diagnóstica ou de triagem dos casos, pelo nível de adesão do profissional de saúde ao registro no prontuário e do paciente ao informar a ocorrência dos sintomas e pela cobertura vacinal alcançada. Com os objetivos de avaliar a efetividade e impacto econômico da campanha de vacinação para influenza, optou-se por um desenho estudo observacional de coorte histórico com características de estudo de intervenção baseado em dados históricos da campanha de 2008 e informações individuais sobre a frequência de sintomas respiratórios e absenteísmo, idade, gênero, função (administrativa e operacional) e renda, comorbidades relevantes e tabagismo, obtidas mediante revisão de prontuário dos 12 meses subsequentes, comparadas entre os grupos de vacinados e não-vacinados (qui-quadrado e test t) e analisadas por regressão logística, e estimada a fração prevenível (proporção de episódios potenciais de influenza evitados pela vacinação). Foram analisados os prontuários de 2.425 trabalhadores (1.651 não-vacinados e 754 vacinados) correspondendo à cobertura de 31,1%. A prevalência de influenza observada foi de 10,4% e a vacinação foi efetiva entre os trabalhadores (RR=0,51; IC95% 39-67), quando considerados os sintomas de alta probabilidade de influenza. A fração prevenível foi 0,09 (9 casos evitados a cada 100 trabalhadores vacinados). A campanha de vacinação foi mais efetiva e provocou maior impacto econômico entre os trabalhadores em regime operacional.
