Breast Ultra-Sound image segmentation: an optimization approach based on super-pixels and high-level descriptors
2015
International audience; Breast cancer is the second most common cancer and the leading cause of cancer death among women. Medical imaging has become an indispensable tool for its diagnosis and follow up. During the last decade, the medical community has promoted to incorporate Ultra-Sound (US) screening as part of the standard routine. The main reason for using US imaging is its capability to differentiate benign from malignant masses, when compared to other imaging techniques. The increasing usage of US imaging encourages the development of Computer Aided Diagnosis (CAD) systems applied to Breast Ultra-Sound (BUS) images. However accurate delineations of the lesions and structures of the b…
An optimization approach to segment breast lesions in ultra-sound images using clinically validated visual cues
2015
International audience; As long as breast cancer remains the leading cause of cancer deaths among female population world wide, developing tools to assist radiologists during the diagnosis process is necessary. However, most of the technologies developed in the imaging laboratories are rarely integrated in this assessing process, as they are based on information cues differing from those used by clinicians. In order to grant Computer Aided Diagnosis (CAD) systems with these information cues when performing non-aided diagnosis, better segmentation strategies are needed to automatically produce accurate delineations of the breast structures. This paper proposes a highly modular and flexible f…
The effect of learning-based distinctive competencies on firm performance: a study of spanish hospitality firms
2011
In spite of the importance of knowledge assets, few empirical studies have examined how knowledge is generated in organizations and the effect of knowledge management on learning-based competencies. This research studies the effect of introducing knowledge management programs in the development of learning-based distinctive competencies as these factors relate to a firm¿s performance. Based on responses from managers at 193 Spanish hospitality firms, the study concludes that the introduction of knowledge management principles and practices promotes creation of learning-based distinctive competencies, which, in conjunction with a knowledge management approach, has a positive causal relations…
PEDAGOGICAL CONFLICT – THE CONTEMPORARY TECHNOLOGY OF THE COMPETENCY-BASED APPROACH
2019
In the 21st century, the creative role of education in the socio-economic development is increasing. Therefore, education is focused not only on the acquisition of certain amount of knowledge by learners, but also on the development of creative abilities and personal qualities, including the ability and desire to study, the ability and desire to act and the ability and desire to create. These key competencies develop in the process of learning on the basis of the technologies of the competency-based approach. The research problem is the development of positive learning motivation for students as the means of transforming inter-personal conflict into pedagogical conflict, which promotes indi…
Unveiling the needs of students who stutter in the language skills - a study on anxiety and stuttering in EFL learning
2019
The aim of this study is to discuss the needs of learners who stutter (LWS) in the skills of speaking, listening, reading, and writing in English as a foreign language (EFL) learning based on their levels of anxiety, and their experiences as individuals who stutter in the process of learning this language. To this end, the anxiety of these students (n = 16) in the foreign language was measured using the Foreign language classroom anxiety scale (FLCAS), and the Specific language skills anxiety scale (SLSAS), whilst their experiences were elicited through semi-structured interviews. Their foreign language anxiety (FLA) levels were then compared to those obtained from a control group of non-st…
