    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 (HAVideo

    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 studentā€™s 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 studentā€™s 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 studentā€™s later professional behavior in advocacy work as well as in relationships with supervisors and other social workers

    Andrew Orta ha definido la TeologiĢa de la InculturacioĢn como una tendencia de la Iglesia catoĢlica de ā€œcodificar y reforzar la religiosidad indiĢgena como parte del esfuerzo maĢs amplio de la Iglesia de abarcar ā€˜las teologiĢas localesā€™ e ā€˜inculturarseā€™ dentro de los contextos culturales especiĢficosā€ (Orta, 2004: 105). DespueĢs de siglos de predicar que los indiĢgenas deben abandonar sus praĢcticas culturales y sus creencias tradicionales, y convertirse en cristianos, muchos misioneros catoĢlicos, en la actualidad, aseguran que las creencias indiĢgenas ya eran de por siĢ cristianas: los indiĢgenas deberiĢan volver a ser maĢs ā€œindiosā€ y regresar a sus tradiciones ancestrales ya que los misioneros las consideran ahora expresiones culturales locales de los valores cristianos (Orta, 2004: vii).
