Monitoring water and carbon fluxes at fine spatial scales using HyspIRI-like measurements
2012
Remotely sensed observations in the visible to the shortwave infrared (VSWIR) and thermal infrared (TIR) regions of the electromagnetic spectrum can be used synergistically to provide valuable products of land surface properties for reliable assessments of carbon and water fluxes. The high spatial, spectral and temporal resolution VSWIR and TIR observations provided by the proposed Hyperspectral - InfraRed (HyspIRI) mission will enable a new era of global agricultural monitoring, critical for addressing growing issues of food insecurity. To enable predictions at fine spatial resolution (<100m), modeling efforts must rely on a combination of high-frequency temporal and highresolution spa…
Extension of Deflection Coefficient for Linear Fusion of Quantized Reports in Cooperative Sensing
2014
Maximizing the so-called deflection coefficient is commonly used as an effective approach to design cooperative sensing schemes with low computational complexity. In this paper, an extension to the deflection coefficient is proposed which captures the effects of the quantization processes at the sensing nodes, jointly with the impact of linear combining at the fusion center. The proposed parameter is then used to formulate a new mixed-integer nonlinear programming problem as a fast suboptimal method to design a distributed detection scenario where the nodes report their sensing outcomes to a fusion center through nonideal digital links. Numerical evaluations show that the performance of the…
Mappatura del deflusso annuo superficiale in Sicilia
2007
Nella risoluzione di numerosi problemi pratici dell’idrologia delle acque superficiali è importante poter far affidamento su informazioni relative ai deflussi che siano contemporaneamente affidabili e diffuse sul territorio.La creazione di uno strumento capace di restituire il deflusso e soprattutto la portata che attraversa una determinata sezione di un corso d’acqua è di fondamentale importanza sia per la pianificazione delle risorse idriche in una data regione sia per l’individuazione delle possibili zone soggette al rischio della desertificazione. La stima del deflusso superficiale permette inoltre la determinazione dei concentrazione degli inquinanti, concentrati o diffusi, nei corpi i…
Extraction et évaluation de caractéristiques adaptées pour la classification du Lentigo à partir d’images de Microscopie Confocale
2019
International audience; La détection de cancer de la peau est l’un des défis de ces dernières décennies. Par ailleurs, diverses techniques d’imagerie ont pour objectif d’aider à la reconnaissance de ces pathologies malignes en contexte clinique. La Microscopie Confocale par Réflectance est un exemple de technique d’imagerie adaptée à la détection de maladie de la peau sur laquelle nous nous basons pour la détection de Lentigo. Les travaux présentés dans cet article portent sur la classification de ces images en trois catégories : sain, bénin et malin. Dans ce but, nous proposons et évaluons deux méthodes d’extraction de caractéristiques basées sur les descripteurs d’Haralick pour l’une et s…
Profesorado : revista de curriculum y formación del profesorado
1997
A partir de las revisiones sobre la investigación de la enseñanza básicamente se hace referencia a tres imágienes de "ser profesor", de llevar a cabo el trabajo docente: "el profesor como persona efectiva", cuyas características personales son determinantes para el desarrollo de una buena enseñanza; "el profesor como técnico" que domina una serie de destrezas que actúan como causa del aprendizaje eficaz; el profesor como "profesional que toma decisiones", destacando la importancia de los aspectos cognitivos. Finalmente, en los últimos tiempos aparece con un alto nivel de redundancia el profesor como "artista, como investigador y como agente de cambio" considerando que la función docente es …
The sociologist as cruiser: Masculinities, deviance and sexuality in gay sex work arenas
2019
This article explores the methodological and ethical issues that arise from ethnographic research in sexual practices in the study of non-normative sexualities. It explores the researcher as a subject in the research as well as doing the research. Taking a queer approach, it identifies key themes and issues that the reflexive researcher faces when in the field.

Transformative Authorship Through Critical Dialogue : Concepts, Theory, and Practice
2021
This conceptual article deals with components and concepts of transformative learning, emphasizing the organization-level perspective on critical reflection. The discussion leans on the concept of transformative authorship and it is argued that it enables authoring processes through which professionals can recognize and recreate their routinized work practices. The aim of the research is to explore how professional experiences are integrated with reflexive, theoretical knowledge through critical dialogue. The authoring process of transformative authorship is illustrated with two complementary case studies from postgraduate health care education. In both cases, the learning tasks were desig…

Supporting student teachers’ reflection through assessment : The case of reflective podcasts
2023
Reflection is a key learning objective of teacher education, yet little is known about the ways in which it could be supported through assessment. In this case study (N = 14), we examine the potential of a novel assessment task—reflective podcasting—in supporting first-year student teachers’ reflection. We analyzed student group podcasts and corresponding student reflections and found that the task engendered reflection. Three theory-driven dimensions were constructed to emphasize the unique nature of podcasts for student reflection: experientiality, authenticity, and communality. We encourage factoring these dimensions into assessment designs that seek to foster student reflection. peerRev…
