Coarse-to-Fine Adaptive People Detection for Video Sequences by Maximizing Mutual Information
Applying people detectors to unseen data is challenging since patterns distributions, such
as viewpoints, motion, poses, backgrounds, occlusions and people sizes, may significantly differ
from the ones of the training dataset. In this paper, we propose a coarse-to-fine framework to adapt
frame by frame people detectors during runtime classification, without requiring any additional
manually labeled ground truth apart from the offline training of the detection model. Such adaptation
make use of multiple detectors mutual information, i.e., similarities and dissimilarities of detectors
estimated and agreed by pair-wise correlating their outputs. Globally, the proposed adaptation
discriminates between relevant instants in a video sequence, i.e., identifies the representative frames
for an adaptation of the system. Locally, the proposed adaptation identifies the best configuration
(i.e., detection threshold) of each detector under analysis, maximizing the mutual information to
obtain the detection threshold of each detector. The proposed coarse-to-fine approach does not
require training the detectors for each new scenario and uses standard people detector outputs, i.e.,
bounding boxes. The experimental results demonstrate that the proposed approach outperforms
state-of-the-art detectors whose optimal threshold configurations are previously determined and
fixed from offline training dataThis work has been partially supported by the Spanish government under the project TEC2014-53176-R

Social climate in social work training : the influence of the learning environment on the emerging social worker\u27s professional identity as an agent of social justice
In Master of Social Work programs, one of the objectives of the field practicum is the development of a professional self. A field placement agency may encourage, discourage, and/or limit the studentās ability to implement social justice interventions in their work with clients which may impact their development of a professional identity as it relates to social justice. In this exploratory study, qualitative data was obtained through eight semi-structured interviews. The findings confirm that the social climate of a field placement agency influences the studentās ability to develop aspects of their professional identity dedicated to engaging in social action activities. Additionally, these experiences were found to have long-term consequences on the studentās later professional behavior in advocacy work as well as in relationships with supervisors and other social workers
Luchas por el significado del teĢrmino āindiĢgenaā en la teologiĢa de la inculturacioĢn en Ecuador
Andrew Orta ha definido la TeologiĢa de la InculturacioĢn como una tendencia de la Iglesia catoĢlica de ācodificar y reforzar la religiosidad indiĢgena como parte del esfuerzo maĢs amplio de la Iglesia de abarcar ālas teologiĢas localesā e āinculturarseā dentro de los contextos culturales especiĢficosā (Orta, 2004: 105). DespueĢs de siglos de predicar que los indiĢgenas deben abandonar sus praĢcticas culturales y sus creencias tradicionales, y convertirse en cristianos, muchos misioneros catoĢlicos, en la actualidad, aseguran que las creencias indiĢgenas ya eran de por siĢ cristianas: los indiĢgenas deberiĢan volver a ser maĢs āindiosā y regresar a sus tradiciones ancestrales ya que los misioneros las consideran ahora expresiones culturales locales de los valores cristianos (Orta, 2004: vii).

Literature circles : Latina/o students' daily experiences as part of the classroom curriculum
textAfter the Mexican-American war, the educational experience of Mexican and Mexican -American students was one of segregation, discrimination, and inequalities. Latina/o histories and funds of knowledge have not been historically part of the classroom curriculum. Although scholars, educators, and social movements have challenged such inequalities, they still persist. Students became objects of the educational process. New theories and educational practices, such as critical pedagogy, have helped empowered students to become aware of their situation and encouraged students to become social agents of change. Literature circles, an educational practice of critical pedagogy, enable educators to provide students with an educational experience where they become the Subjects of their own learning; thus, transforming their educational experiences.Curriculum and Instructio
