Using Self-Organizing Maps to Recognize Acoustic Units Associated with Information Content in Animal Vocalizations

Kohonen self-organizing neural networks, also called self-organizing maps (SOMs), have been used successfully to recognize human phonemes and in this way to aid in human speech recognition. This paper describes how SOMS also can be used to associate specific information content with animal vocalizations. A SOM was used to identify acoustic units in Gunnison’s prairie dog alarm calls that were vocalized in the presence of three different predator species. Some of these acoustic units and their combinations were found exclusively in the alarm calls associated with a particular predator species and were used to associate predator species information with individual alarm calls. This methodology allowed individual alarm calls to be classified by predator species with an average of 91% accuracy. Furthermore, the topological structure of the SOM used in these experiments provided additional insights about the acoustic units and their combinations that were used to classify the target alarm calls. An important benefit of the methodology developed in this paper is that it could be used to search for groups of sounds associated with information content for any animal whose vocalizations are composed of multiple simultaneous frequency components

Ghosts, Words, Memories and Stories in Katherine Anne Porter’s “Old Mortality” and Sandra Cisneros’s The House on Mango Street

[Abstract] Katherine Anne Porter was born in 1890 and she published “Old Mortality” in 1937; she was an acclaimed writer of short stories when Sandra Cisneros was born in 1954, and she had been dead for more than ten years when the latter first published The House on Mango Street. In spite of the chronological distance that separates both writers, and in spite of the different life experiences which determined their development, their works show the existence of certain interests in common. In this paper I explore some of these aspects of their fiction by focusing on Porter’s “Old Mortality” and Cisneros’s The House on Mango Street. Both works deal with the childhood and adolescence of two especially sensitive young girls, Miranda and Esperanza, who at the end of their stories still dream of a future of freedom and independence. But Miranda’s and Esperanza’s hopeful dreams are very different: while Miranda feels that she needs to break with her family and their stories about the past in order to be independent and “know the truth about what happens to [her] ”, Esperanza seems to have gone a step further, and she knows that her dream of a future life away from Mango Street will eventually bring her back to this place and its people. Thus, Esperanza shows a more complete understanding of her existence: she knows that her future dream will require her acknowledgement of the past. This means that she is ready to establish the dialogue between memory and the self which was essential in Porter’s fiction and which Miranda fails to achieve at the end of “Old Mortality.” In this paper I suggest that at least one of the reasons for the difference between these two characters’ final reactions can be found in the different role of language, words and stories in both texts

A Proposition for Geodetic Recording of Active Fault Zones

Establishing recent displacements along faults is an important and delicate task. Larger\ud faults are accompanied by broader fault zones that require a specific approach to geodetic\ud measurements of fault block displacements. The vector of fault block displacements, or\ud resultant, is a vector sum of differential displacements within the fault zone. For the purposes\ud of recording the displacements we propose the stabilization of a geodetic network of\ud points positioned in fault blocks outside the fault zone, whereby the displacements would\ud be manifested in the deformation of the network. The resultant displacement vector can\ud then be derived from the latter deformation, and from that, the dip and strike of the fault\ud zone as well as the extent of the displacement
