    La presente investigación partió del problema: ¿Existen diferencias esenciales de autoestima, según sexo, ciclo, edad y tipo de familia, en los estudiantes de Educación Primaria de la Institución Educativa Nº 30307 de Santa Rosa de Tistes- Chambará? Como objetivo se propuso Identificar las diferencias esenciales de autoestima, según sexo, ciclo, edad y tipo de familia, en los estudiantes de la muestra. El método general que se utilizó fue el método científico y como método específico, el método descriptivo con un diseño descriptivo comparativo. La población estuvo constituida por todos los estudiantes de Educación Primaria de la Institución Educativa Nº 30307 de Santa Rosa de Tistes- Chambará y la muestra está compuesta por los 50 estudiantes de Educación Primaria de la Institución Educativa Nº 30307 de Santa Rosa de Tistes- Chambará. La investigación fue de tipo psicometría, empleando el instrumento Test de Autoestima, de Antonio M. Serrano Muñoz (2013). Para el tratamiento estadístico de los datos se utilizó los estadígrafos de media aritmética, desviación estándar, el porcentaje, la varianza muestral y la prueba de hipótesis de diferencia de medias. Se concluyó que la autoestima de los estudiantes del sexo femenino es superior con respecto a los estudiantes de sexo masculino, sin embargo no resulta significativa, además hay una diferencia significativa a favor de los estudiantes mayores con respecto a los estudiantes menores; se obtuvieron también diferencias significativas entre los estudiantes del III, IV y V ciclos y por último, hay diferencia pero no significativa a favor de los estudiantes de familias incompletas en relación a las de familias completas.Tesi

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Recomendações para a incorporação de agregados resultantes de RCD em betões de ligantes hidráulicos – Um contributo

    Neste artigo apresentam-se recomendações técnicas gerais, com base nos resultados obtidos no âmbito do projeto de investigação “30307 – MULTIVALOR RCD – Otimização do Processo de Valorização de Resíduos de Construção e Demolição por Caracterização Mecânica, Física, Química e Ambiental”. As recomendações aqui apresentadas são relativas às medidas necessárias para incorporar os agregados resultantes de RCD em betões de ligantes hidráulicos. Pretende-se contribuir para a criação de condições mais favoráveis para a produção de agregados reciclados comerciáveis, respeitando os requisitos da regulamentação europeia em vigor. Procura-se assim produzir agregados reciclados que conduzam a betões mais sustentáveis e que ao mesmo tempo apresentem características de estabilidade, deformabilidade e durabilidade aceitáveis. O trabalho desenvolvido no âmbito do projeto permitiu identificar oportunidades de melhoria em todas as fases. Nomeadamente na fase de demolição, processamento e armazenamento, assim como na fase de produção do betão a partir das características intrínsecas dos agregados reciclados. São ainda apresentadas reflexões para a prescrição do betão com agregados reciclados em fase de projeto.European Regional Development Fund, via PO Algarve, concedido ao projeto QREN 30307 Multivalorinfo:eu-repo/semantics/publishedVersio

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    We 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

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
