La percepción de estudiantes de agronomía sobre la contaminación por agroquímicos
Get PDFThis research involves an interdisciplinary study on the perception of agrochemical pollution in students from six Mexican universities enrolled in agronomic science engineering programs and related areas, such as agroecology, agroforestry engineering, and innovation for sustainable agriculture. The research method is mixed with an exploratory approach; data were collected in an online questionnaire, measuring attitudes, values, and actions related to the use of agrochemicals, as well as a self-assessment knowledge test about pesticides, fertilizers, and their effects on the environment and human health. The theoretical approach emerges from environmental psychology, agroecology, and environmental education. A theoretical model is proposed to explore the formation of mental models and beliefs about sustainable agricultural systems, and recommendations are made for optimizing agronomic science engineering programs with a focus on sustainability. The results show a high level of environmental awareness in students, a low perception of social norms for environmental conservation, and the perception of agrochemicals as essential for production, representing a cognitive barrier to implementing sustainable agricultural strategies.Esta investigación involucra un estudio interdisciplinario sobre la percepción de la contaminación por agroquímicos en estudiantes de seis universidades mexicanas que cursan programas de ingeniería en agronomía y áreas afines, como agroecología, ingeniería agroforestal e innovación agrícola sustentable. El método de investigación es mixto con corte exploratorio, se recolectaron datos en un cuestionario en línea, sobre las actitudes, valores y acciones relacionadas al uso de agroquímicos, además de una autoevaluación de conocimientos sobre plaguicidas, fertilizantes y sus efectos en el ambiente y la salud humana. El enfoque teórico surge de la psicología ambiental, así como de la agroecología y de la educación ambiental. Se propone un modelo teórico para explorar la formación de modelos mentales y creencias sobre sistemas agrícolas sustentables y se plantean recomendaciones para la optimización de programas académicos de ingenierías en agronomía con enfoque hacia la sustentabilidad. Los resultados demuestran un alto nivel de consciencia ambiental en los estudiantes, una baja percepción de normas sociales para la conservación ambiental y la percepción de los agroquímicos como indispensables para la producción, lo que representa una barrera cognitiva para la implementación de estrategias agrícolas sustentables
La percepción visual del paisaje en la pintura y la fotografía: Un enfoque interdisciplinario hacia la presencia espacial
Get PDFThis article explores visual perception as an embodied experience of space through landscape painting and photography. It takes an interdisciplinary approach, which seeks to contribute to the dialogue between different fields of study: phenomenology of perception, perception of space in cognitive neuroscience and visual arts. This research is correlational and descriptive; it seeks, on one hand, to explore the relationship between the experience of spatial presence and realism; on the other, it observes the use of affordances in landscape images, understood as visual elements that suggest a motor action in the spectator and the ways in which they affect the intensity of spatial presence. In addition to the literature analysis, data was collected through an illustrated questionnaire which included 26 images: 13 paintings and 13 landscape photographs. This study was conducted with 28 participants aged 18 to 64 years of different genders.Este artículo explora la percepción visual como experiencia corporizada del espacio a través del paisaje en la pintura y la fotografía. Es una investigación interdisciplinaria, que busca contribuir al diálogo entre varios campos: la fenomenología de la percepción, la percepción del espacio en la neurociencia cognitiva y el estudio de las artes visuales. La investigación es de carácter correlacional y descriptivo; busca por una parte, explorar la relación entre la experiencia de presencia espacial y el realismo de la imagen; por otra, se observa si el uso de elementos visuales que sugieren una acción motora en el espectador (del inglés ‘affordances’)afecta la intensidad de presencia espacial. Además del análisis de literatura, se recolectaron datos a través de un cuestionario ilustrado en donde se presentaron 26 imágenes, 13 pinturas y 13 fotografías de paisaje. Este estudio se realizó con 28 participantes de 18 a 64 años de distintos géneros

La investigación basada en la práctica de las artes y los medios audiovisuales
No full textLa investigación basada en la práctica de las artes y los medios audiovisuales es un género metodológico que se utiliza principalmente en Europa y Estados Unidos en disciplinas que cuentan con un componente práctico o de producción, como las artes visuales, los medios de comunicación, el diseño, la arquitectura y los estudios cinematográficos. Este artículo analiza esa vía de investigación y sus metodologías, explorando su validación e implementación en un contexto latinoamericano. La discusión aborda algunos de los retos a los que dicha vía se enfrenta en relación con los métodos dominantes de la investigación científica, el discurso positivista y el lugar de la subjetividad y la autobiografía como nociones fundamentales en la investigación basada en la práctica de las artes y los medios audiovisuales. Asimismo, el trabajo discute algunas de las direcciones epistemológicas que surgen de esta vía de investigación en un marco contemporáneo.Research based on participation in art and audiovisual media is a methodological genre used primarily in Europe and the United States in disciplines that have a practical or productive component, such as the visual arts, communication media, design, architecture, and cinema. This article analyzes such research and its methodologies, exploring its validation and implementation in a Latin American context. The discussion addresses some of the challenges that such research faces in relation to the dominant methods of scientific research, positivist discourse, and the place of subjectivity and autobiography as fundamental notions in research based on participation in art and audiovisual media. The paper also discusses some of the epistemological directions that arise from this sort of research in a contemporary framework
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
Variations on the Author
Get PDF“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 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
