We present an image-based approach to infer 3D structure parameters using a probabilistic "shape+structure'' model. The 3D shape of a class of objects may be represented by sets of contours from silhouette views simultaneously observed from multiple calibrated cameras. Bayesian reconstructions of new shapes can then be estimated using a prior density constructed with a mixture model and probabilistic principal components analysis. We augment the shape model to incorporate structural features of interest; novel examples with missing structure parameters may then be reconstructed to obtain estimates of these parameters. Model matching and parameter inference are done entirely in the image domain and require no explicit 3D construction. Our shape model enables accurate estimation of structure despite segmentation errors or missing views in the input silhouettes, and works even with only a single input view. Using a dataset of thousands of pedestrian images generated from a synthetic model, we can perform accurate inference of the 3D locations of 19 joints on the body based on observed silhouette contours from real images.

Anthropogenic influences and climate change are warming rivers in New Brunswick and threatening the cold water habitats of native salmonids. When ambient river temperatures in summer exceed the tolerance level of Atlantic salmon and brook trout, individuals behaviourally thermoregulate by seeking out cold water refugia. These critical thermal habitats are often created by tributaries and concentrated groundwater discharge. Thermal infrared imagery was used to map cold water anomalies along a 53 km reach of the Cains River on 23 July 2008. Although efficient and useful for mapping surface temperature of a continuous stream reach, the fish did not use all identified thermal anomalies as refugia. Overall, 100 % of observed large brook trout >35 cm in length were found in 30 % of the TIR-mapped cold water anomalies. Ninety eight percent of observed small brook trout 8 – 30 cm in length were found in 80 % of the mapped cold water anomalies and their densities within anomalies were significantly higher than densities outside of anomalies. Fifty nine percent of observed salmon parr were found in 65 % of the mapped anomalies; however, they were dispersed within study sites and their densities were not significantly different within anomalies compared to outside of the anomalies. No brook trout were observed at the seven noncold water study sites that were investigated. Preference curves for various habitat variables including velocity, temperature, depth, substrate, and deep water availability near cold water anomalies were developed based on field investigations during high temperature events (ambient river temperature >21 oC). Combined with thermal imagery, managers can use the physical descriptions of thermal refugia developed here as a tool to help conserve and restore critical thermal refugia for Atlantic salmon and brook trout on the Cains River, and potentially similar river systems.

This chapter compares spatial constructs in mental imagery to spatial constructs in non-metaphorical and metaphorical language. The study is based on a psycholinguistic survey of people’s mental imagery for paths and roads, and a previous corpus-linguistic investigation of path- and road-instances from the British National Corpus (the BNC) (see Johansson Falck 2010). The aim is to investigate if spatial path and road constructs in mental imagery focus on similar aspects as those in metaphorical language. The study shows that mental imagery and metaphorical language are more restricted than non-metaphorical language, and typically are related to the specific anticipations for bodily action that paths and roads afford. The focus is on function, which influences both direction and manner of motion. / Embodiment of Motion Metaphors

Hypertension occurs in nearly 10% of pregnancies, and is associated with infant and maternal morbidity and mortality. Prior studies of non-pregnant adults have demonstrated the effectiveness of a variety of relaxation therapies in reducing blood pressure. A pilot randomized controlled trial was conducted, the purposes of which were 1) to provide preliminary evidence regarding the usefulness of guided imagery (GI) in reducing blood pressure in hypertensive pregnant women, and 2) to answer feasibility questions for a larger trial. Pregnant women with hypertension prior to 37 weeks gestation (n = 69) were randomized to either 15-minute periods of guided imagery (n = 34), or of quiet rest (QR) (n = 35), twice daily for four weeks or until delivery, whichever came first. Daytime ambulatory mean arterial pressure (MAP), systolic and diastolic blood pressures, anxiety, rest and GI use were measured weekly, to a maximum of four weeks. Sixty women completed at least one week in the study; 46.4% completed four weeks. Compliance was excellent. Intention to treat analysis was used. In the unadjusted analysis, women allocated to GI had significantly lower average daytime ambulatory mean MAP elevations from baseline to their last week of study participation than women allocated to quiet rest (GI: M = 1.58 mmHg, SD = 7.63; QR: M = 5.93 mmHg, SD = 6.55; t = 2.36, p = .02). However, the effect was no longer statistically significant (p = 0.14) when adjusted for baseline mean arterial pressure and gestation. There was no statistically significant difference in the numbers of women who were prescribed antihypertensive medication after randomization (GI: n = 16, QR: n = 13, X2 = 0.74, p = .46). There was also no evidence of an effect of guided imagery on anxiety. Nearly 90% (n = 26) of the guided imagery group indicated they would use it again, either in a subsequent pregnancy or during stressful life events. Given the ease of use, low cost, acceptability to women, and lack of risk of guided imagery, an adequately-powered randomized controlled trial is warranted.

Kara Walker, winner of the MacArthur “Genius” award and the Smithsonian Lucelia award, is one of the most critically acclaimed contemporary African American artists. Her work, especially her cut-paper silhouettes depicting grotesque antebellum scenes, has inspired as much outrage from an older generation of Black artists as acclaim from the mainstream media. This thesis gives an overview of the artist’s life, analysis of some of her works, and an examination of the controversy her work has caused. In the conclusion, I introduce the next generation of Black American artists, self-proclaimed “Art Stars,” including Atlanta artist Fahamu Pecou.

The purpose of this thesis paper is to investigate womanist theology and method, along with restoration practices involving spirituality and healing within the context of the visual arts. The thesis exhibition will attempt to create new visual possibilities that inform womanist theological scholarship in terms of promoting contemporary female religious imagery within a metaphorical language. While womanist theology is steeped in interdisciplinary practices, it has yet to consider seriously the studio arts as a means to explore and develop the womanist language. This study will investigate how essential and natural the visual arts assist our understanding of spirituality, especially through a womanist context.

This qualitative study sought to answer: How may I, as an artist, use art for my own transformation and healing? I am an artist and teacher living with chronic pain and fatigue and wanted to find healing through art and inspire others to do the same. During the three month study, I made artwork, reflected in my journal, and practiced guided imagery. The journal was used to reflect on my health, the creative process, and to record ideas generated through guided imagery. Findings showed that short term relief was provided during the act of creation, but no long-term relief was achieved. The primary conclusion was that I was able to use art for healing and transformation, but only after experimentation and reflection. By adapting the creative process to accommodate for my illness, I was able to include art making as part of a healthy life.

Abstract The act of knowing is a critical determinant of what is known, yet there are limits and potential violence inherent in all ways of knowing. Social workers have an ethical responsibility to understand our means of knowing and our knowledge claims – both shape the work we do. Conspicuously under-represented as creators of/commentators on how they are represented, people with intellectual disabilities have had little/no control over what or how they are known. These ethical and epistemological concerns were the focus of this arts-informed qualitative study. The purpose was an interrogative encounter with one way of knowing – how public photographic imagery of people with intellectual disabilities influences knowledge about them. It was concerned, however, to come to this knowledge through an inquiry into how labelled people would, themselves, interpret and respond to these representations, and how they might use photography to trouble disabling images and non-disabled (social work) knowing. Theoretically framed by a critical disability lens, the work was influenced, too, by Derrida’s essay on photography, “The Right of Inspection”. The other regarding aspect of the philosophy of Emmanuel Levinas, his concern with our ethical responsibility to the alterity of the Other, most powerfully informs the work. Four adults with intellectual disabilities accepted the invitation to participate in this project. First, they critically engaged with a selection of public photographic images. In a unique methodological turn, they then transformed the images to reflect their critique. Interpretive analysis of the critiques and transformations identified four thematic ideas. Participants’ critiques were insightful and profound; transformations provocative and disruptive. Challenging dominant assumptions – and demanding non-disabled others re-think intellectual disability and people so labeled – the critiques and transformations also respond to the social/political/ideological/psychological ramifications of photographic imagery on the lived experience of intellectual disability. Through the work, participants confront non-disabled responses to public photographs and to labeled people, challenging non-disabled others to question their knowledge, attitudes, and behaviours. The work also raises questions about research and people with intellectual disabilities: the possibilities for voice and empowerment through inclusive research strategies and visual methodologies, and the transformative potential of dialogic encounters between people with and without intellectual disabilities.

The current study explored the influence of priming vantage point at retrieval on the recall of younger and older adults, in addition to the effects of visualization ability on recall. Based on McIsaac and Eich’s (2002) findings of the effects on younger adults’ recall, it was hypothesized that recollections would be more likely to include certain features when retrieved through the field vantage point (FVP) than through the observer vantage point (OVP) and vice-versa. Additionally, it was expected that older adults would recall more detailed memories from the OVP than from the FVP. Finally, it was hypothesized that visualization ability would influence memory vividness and that it would be more influential in older adults than in younger adults. The experiment was conducted across two sessions. In Session 1, participants completed a visual imagery assessment, and memories were created in the laboratory with younger (n = 20; 18-21 years old) and older (n = 18; 63-88 years old) adults through the completion of two activities. In Session 2, participants recalled the activities from either the FVP or the OVP. Participants’ recollections were coded for various memory characteristics, which acted as dependent variables in analyses. A significant interaction effect (p = .003) between age and vantage point was found on the characteristic of psychological state, such that older adults referred to their psychological state in FVP memories more than in OVP memories (p = .002), while younger adults demonstrated no significant difference. Imagery ability significantly predicted several aspects of participants’ subjective recall experience. Overall, the results indicate that retrieval vantage point does not change the content of one’s recollections on most measures for either younger or older adults and that visual mental imagery ability predicts several aspects of one’s recall experience.

My thesis is about Virginia Woolf’s novels, Mrs. Dalloway, The Waves, and To the Lighthouse. I examine these novels in relation to the theories of Henri Bergson, William James, and Sigmund Freud, and the groundwork of Modernism. I relate Woolf's use of water imagery and stream of consciousness technique to Bergson’s theory of “la durée,” or psychological, subjective time, James’ “stream of consciousness” theory in psychology, and Freud’s theory of the “oceanic” feeling of religious experience.
