this study was conducted to identify self-directed and external professional development obstacles facing primary school efl teachers in southern zone of tigray region in ethiopia. the participants of the study were 63 primary school efl teachers, 10 school principals and 2 clusters of supervisors. school teachers were selected using random sampling technique whereas school principals and clust...

The construction of the identity of a professional group is the subjective dimension of its professionalization process, understood as a process of affi rmation, autonomy construction and social recognition(1-2). Because it is founded on relationships, of recognition or non-recognition, identity is a concept that is related to communication, but it is translated into objective dimensions of the...

Even with the recent advances in convolutional neural networks (CNN) in various visual recognition tasks, the state-of-the-art action recognition system still relies on hand crafted motion feature such as optical flow to achieve the best performance. We propose a multitask learning model ActionFlowNet to train a single stream network directly from raw pixels to jointly estimate optical flow whi...

Although OWL provides a solid basis for many semantic-web applications, it lacks sufficient declarative semantics for instance recognition. This omission prevents OWL from being a satisfactory ontology language for automated semantic annotation. We can resolve this problem by adding to ontological OWL declaration epistemological instance recognition semantics that include external representatio...

The transmission of the entire video and audio sequences over an internal or external network during the implementation of audio-visual recognition over internet protocol is inefficient especially when only selected data out of the entire video and audio sequences are actually used for the recognition process. Hence, in this paper, we propose an efficient method of implementing audio-visual rec...

Although face recognition has become a topic of active research in recent decades, an accurate face recognition is still a tough job and still struggle with its performance especially if it is unconstrained lighting variations. The external conditions present during the facial image acquisition stage deeply influence the appearance of a face in the acquired image and hence affect the performanc...

Recognizing commonly used data structures and algorithms is a key activity in reverse engineering. Systems developed to automate this recognition process have been isolated, stand-alone systems, usually targeting a speciic task. We are interested in applying recognition to multiple tasks requiring reverse engineering , such as inspecting, maintaining, and reusing software. This requires a exibl...

Perception and eye movements are affected by culture. Adults from Eastern societies (e.g. China) display a disposition to process information holistically, whereas individuals from Western societies (e.g. Britain) process information analytically. Recently, this pattern of cultural differences has been extended to face processing. Adults from Eastern cultures fixate centrally towards the nose w...
