Computational ethology for primate sociality: a novel paradigm for computer-vision-based analysis of animal behaviour

Research in the biological and wildlife sciences is increasingly reliant on video data for measuring animal behaviour, however large-scale analysis is often limited by the time and resources it takes to process video archives. Computer vision holds serious potential to unlock these datasets to analyse behaviour at an unprecedented level of scale, depth and reliability, however thus far a framework for processing and analysing behaviour from large-scale video datasets is lacking. This thesis attempts to solve this problem by developing the theory and methods for capturing long-term sociality of animal populations from longitudinal video archives, laying the foundations for an emerging field; computational ethology of animals in the wild. It makes several key contributions by a) establishing the first unified longitudinal video dataset of wild chimpanzee stone tool use across a 30 year period, and building a framework for collaborative research using cloud-technology b) developing a set of computational tools to allow for processing of large volumes of video data for automated individual identification and behaviour recognition c) applying these automated methods to validate use for social network analysis and d) measuring the social dynamics and behaviour of a group of wild chimpanzees living in the forest of Bossou, Guinea, West Africa. In Chapter 1 I introduce the theoretical and historical context for the thesis, and outline the novel methodological framework for using computer vision to measure animal social behaviour in video. In Chapter 2 I introduce the methodology for processing and managing a longitudinal video archive, and future directions for a new framework for collaborative research workflows in the wildlife sciences using cloud technology. In Chapter 3 I lay the foundations of this framework for analysing behaviour and unlocking video datasets, using deep learning and face recognition. In Chapter 4 I evaluate the robustness of the method for modelling long-term sociality and social networks at Bossou and test whether life history variables predict individual-level sociality patterns. In Chapter 5 I introduce the final component to this framework for measuring long-term animal behaviour, through audiovisual behavioural recognition of chimpanzee nut-cracking. In my final chapter (6) I discuss the main contributions, limitations and future directions for research. Overall this thesis integrates a diverse range of interdisciplinary methods and concepts from primatology, ethology, engineering, and computer vision, to build the foundations for further exploration of cognition, ecology and evolution in wild animals using automated methods

Measurements of the vertical profile of water vapor abundance in the Martian atmosphere from Mars Observer

An analysis is presented of the Pressure Modulator Infrared Radiometer (PMIRR) capabilities along with how the vertical profiles of water vapor will be obtained. The PMIRR will employ filter and pressure modulation radiometry using nine spectral channels, in both limb scanning and nadir sounding modes, to obtain daily, global maps of temperature, dust extinction, condensate extinction, and water vapor mixing ratio profiles as a function of pressure to half scale height or 5 km vertical resolution. Surface thermal properties will also be mapped, and the polar radiactive balance will be monitored

Young People’s Narratives of Media and Identity: Mediagraphy as Identity Work in Upper Secondary School

The article explores how upper secondary students use the learning activity mediagraphy to reflect on their identity and on media as constraining and enabling factors in their social practice. In mediagraphy, the students research four generations of their own families, including themselves. They write a mediagraphy essay on the differences and similarities across the generations in media use and turning points in individuals’ lives, in addition to societal and media-related developments. Data from student products and interviews are analysed through three “identity dilemmas” that any identity claim faces: the constant navigation between 1) continuity and change, 2) sameness and difference with regard to others, and 3) agency as “person-to-world” and “world-to-person”. The findings suggest that mediagraphy is a type of identity work that can potentially help students develop an agentive identity in a time of insecurity, with rapidly shifting social and cultural conditions and increasing media density.

Rhode Island Election Tickets: A Survey

Rhode Island was the first English colony in America to issue printed election ballots, with the first issued in the mid-1740s. This survey of Rhode Island election tickets, while not exhaustive, is representative of the use of tickets in elections spanning a period of over 150 years and documents state and local politics, political factions and election results from the Ward-Hopkins controversy of the colonial period to political factions during the War of 1812, the Anti-Masonic period of the 1830s, the Law and Order coalition of the 1840s following events of the Dorr Rebellion, the temperance movement of the 1850s, the pro-Union tickets of the Civil War, and Greenback party and Prohibitory factions of the 1870s and 1880s. Statewide elections for general officers, United States congressional representatives, presidential electors, special purpose elections as well as local elections for city, town and district offices are also examined. The scope of this study includes a survey of tickets found in the collections of the University of Rhode Island Library Special Collections, Rhode Island State Archives, Warwick Historical Society as well as private collections of Henry A.L. Brown, Russell DeSimone, and Daniel Schofield. This document was last revised in 2015. The previous version (2007) can be found below as a supplemental file

I’ve heard that brand before: the role of music recognition on consumer choice

When searching for and buying new products, consumers’ knowledge is often limited, and some (but not all) options in the choice set are unrecognized. In such situations, research on the recognition heuristic shows that people tend to choose more often the recognized option over the unrecognized one, as they infer it has the higher value regarding the criterion being judged. Since humans are particularly good at rapidly recognising familiar music, this paper examines the effect of recognition to influence brand choice when using music as the recognition cue. In two experiments (N = 486), participants were familiarised with several excerpts of advertising music. Participants then performed a choosing task to decide which of two brands they would purchase when searching for different products (e.g., headphones, cameras). Brands were either presented with familiar music clips or completely novel ones. Results showed that pairing brands with music that can be recognised by the target consumers increased brand choice by 6% (d = .21). Importantly, participants’ preferences for the advertising music also influenced brand choice, increasing the effect of recognition when the music was liked and suppressing it in extreme cases when the music was most disliked. This suggests that ad practitioners should use a cue integration framework when working with music, weighing all available musical and extra-musical cues according to their impact on the target consumers. Results are discussed in terms of the practical implications of measuring brand’s ROI when working with music and the value of the heuristics-and-biases framework to study music effects on consumer behaviour
