MosaicShape: Stochastic Region Grouping with Shape Prior

A novel method that combines shape-based object recognition and image segmentation is proposed for shape retrieval from images. Given a shape prior represented in a multi-scale curvature form, the proposed method identifies the target objects in images by grouping oversegmented image regions. The problem is formulated in a unified probabilistic framework and solved by a stochastic Markov Chain Monte Carlo (MCMC) mechanism. By this means, object segmentation and recognition are accomplished simultaneously. Within each sampling move during the simulation process,probabilistic region grouping operations are influenced by both the image information and the shape similarity constraint. The latter constraint is measured by a partial shape matching process. A generalized parallel algorithm by Barbu and Zhu,combined with a large sampling jump and other implementation improvements, greatly speeds up the overall stochastic process. The proposed method supports the segmentation and recognition of multiple occluded objects in images. Experimental results are provided for both synthetic and real images.

The Barretstown experience

The thesis was prompted by a simple clinical observation. Seriously ill children returning from Barretstown Holiday Camp appeared changed. Barretstown ‘magic’ confuses the issue but indicates real and clinically evident transformations. The project sought to understand the experience and place it in a recognisable framework. The data was collected by interviews, observations as camp Paediatrician, memberships of the Child Advisory Committee and the Association’s criteria assessment team, participation in volunteer training and visits to international camps. The research presents evidence that the concepts of rite of passage, graceful mimesis and salutogenesis clarify operative social processes. The passage stages of separation, transition and reaggregation can be identified. Passage rites reorder personal and social upsets to fresh arrangements that facilitate change. Interviews confirm the reordering impact of achievements in play activities. These are challenging experiences closely guided by their Masters of Ceremonies – the Caras. The Cara/camper relationship is crucial and compatible with Girard’s theory of external mimesis. Visits to four camps confirm an inspirational process in contrast to a reported camp with a predetermined formative influence. Charismatic Caras/Councillors inspire playful mimesis and salutogenic transformations. Health is more than correction of pathogenic deficits and restoration of homeostasis. Salutogenic health promotes heterostasis – a desire for optimal experiences underpinned by a sense of coherence and adequate resources. Some evidence is presented that children have an improved sense of coherence after camp, which enables them to cope better with the demands of ill health. The camps enable sick children to up regulate risk taking towards more heterostatic experiences rather than down regulate their expectations. The heterostatic impulse can explain the disability paradox of good quality of life in the presence of severe disability. The salutogenic power of Barretstown can trump the pathogenic effects of childhood cancer and other serious illnesses.

Conversion as transformative experience: a sociological study of identity formation and transformation processes

This thesis contributes to the understanding of the processes involved in the formation and transformation of identities. It achieves this goal by establishing the critical importance of ‘background’ and ‘liminality’ in the shaping of identity. Drawing mainly from the work of cultural anthropology and philosophical hermeneutics a theoretical framework is constructed from which transformative experiences can be analysed. The particular experience at the heart of this study is the phenomenon of conversion and the dynamics involved in the construction of that process. Establishing the axial age as the horizon from which the process of conversion emerged will be the main theme of the first part of the study. Identifying the ‘birth’ of conversion allows a deeper understanding of the historical dynamics that make up the process. From these fundamental dynamics a theoretical framework is constructed in order to analyse the conversion process. Applying this theoretical framework to a number of case-studies will be the central focus of this study. The transformative experiences of Saint Augustine, the fourteenth century nun Margaret Ebner, the communist revolutionary Karl Marx and the literary figure of Arthur Koestler will provide the material onto which the theoretical framework can be applied. A synthesis of the Judaic religious and the Greek philosophical traditions will be the main findings for the shaping of Augustine’s conversion experience. The dissolution of political order coupled with the institutionalisation of the conversion process will illuminate the mystical experiences of Margaret Ebner at a time when empathetic conversion reached its fullest expression. The final case-studies examine two modern ‘conversions’ that seem to have an ideological rather than a religious basis to them. On closer examination it will be found that the German tradition of Biblical Criticism played a most influential role in the ‘conversion’ of Marx and mythology the best medium to understand the experiences of Koestler. The main ideas emerging from this study highlight the fluidity of identity and the important role of ‘background’ in its transformation. The theoretical framework, as constructed for this study, is found to be a useful methodological tool that can offer insights into experiences, such as conversion, that otherwise would remain hidden from our enquiries.

The lived experience of Irish diocesan priests. A qualitative study of clerical identity, obedience and celibacy.

The main aim of this thesis is to document and explore the lived experience of Irish diocesan priests and former priests, in order to explore the reality of diocesan priesthood in contemporary Ireland, and to investigate how, if at all, diocesan priesthood has changed in Ireland during the past fifty years. It sought to do this by interrogating the stories of thirty-three diocesan priests and former priests, and by placing their individual stories within the broader context of Irish society and the Catholic Church, during the fifty-year period, 1962–2012. The research focused on three core areas of priesthood – identity, obedience, and celibacy – and it addressed the following questions. First, how do Irish diocesan priests understand their priesthood and how has this understanding changed over time, if at all? I will argue that three paradigms of priesthood co-exist in the contemporary Irish Church, and that each of these models corresponds with a distinct period in contemporary Irish Church history. I will also demonstrate the existence of underlying similarities in the cultural practice of priesthood that transcend the different generations of priests. Second, how do Irish diocesan priests negotiate their priesthood within a large and complex institution? My study suggests that Irish diocesan priests are typically loyal and obedient. However, they are not necessarily subservient. Third, how do Irish diocesan priests understand and experience celibacy in their day-to-day lives? My study demonstrates that celibacy is typically understood and experienced along a continuum, ranging from total acceptance to total rejection, with most priests somewhere in between. Fourth, I will argue that while priests are experiencing many difficulties in their lives, there is insufficient evidence from the present study to indicate they are experiencing a crisis.

Work experience in transition year: a mixed methods study of subject and career choices

Transition Year (TY) has been a feature of the Irish Education landscape for 39 years. Work experience (WE) has become a key component of TY. WE is defined as a module of between five and fifteen days duration where students engage in a work placement in the broader community. It places a major emphasis on building relationships between schools and their external communities and concomitantly between students and their potential future employers. Yet, the idea that participation in a TY work experience programme could facilitate an increased awareness of potential careers has drawn little attention from the research community. This research examines the influence WE has on the subsequent subjects choices made by students along with the effects of that experience on the students’ identities and emerging vocational identities. Socio-cultural Learning Theory and Occupational Choice Theory frame the overall study. A mixed methods approach to data collection was adopted through the administration of 323 quantitative questionnaires and 32 individual semi-structured interviews in three secondary schools. The analysis of the data was conducted using a grounded theory approach. The findings from the research show that WE makes a significant contribution to the students’ sense of agency in their own lives. It facilitates the otherwise complex process of subject choice, motivates students to work harder in their senior cycle, introduces them to the concepts of active, experience-based and self-directed learning, while boosting their self-confidence and nurturing the emergence of their personal and vocational identities. This research is a gateway to further study in this field. It also has wide reaching implications for students, teachers, school authorities, parents and policy makers regarding teaching and learning in our schools and the value of learning beyond the walls of the classroom.

User experience of mobile cloud applications - current state and future directions

The increasing penetration rate of feature rich mobile devices such as smartphones and tablets in the global population has resulted in a large number of applications and services being created or modified to support mobile devices. Mobile cloud computing is a proposed paradigm to address the resource scarcity of mobile devices in the face of demand for more computing intensive tasks. Several approaches have been proposed to confront the challenges of mobile cloud computing, but none has used the user experience as the primary focus point. In this paper we evaluate these approaches in respect of the user experience, propose what future research directions in this area require to provide for this crucial aspect, and introduce our own solution.

Learning from minority: Exploring Irish Protestant experience

This paper, based on a narrative research inquiry, presents and explores a number of stories relating to the experience and identity of members of the small Irish Protestant minority. Drawing on these stories it uses Foucault’s conceptualisation of power and discourse to consider community, social withdrawal, and two different but linked expressions of silence as acts of resistance. These were simultaneously utilised to preserve a culture and ethos diametrically opposed to the religious and political hegemony of the Irish Catholic state and to combat the threat of extinction. The article concludes that an exploration of Ireland’s traditional religious minority not only raises awareness concerning a specific group’s experience but extends an understanding of the issues with which minorities (in more general terms) may have to cope in order to survive.

A qualitative analysis of parental coping with an early diagnosis of hearing loss in Ireland

The recent implementation of Universal Neonatal Hearing Screening (UNHS) in all 19 maternity hospitals across Ireland has precipitated early identification of paediatric hearing loss in an Irish context. This qualitative, grounded theory study centres on the issue of parental coping as families receive and respond to (what is typically) an unexpected diagnosis of hearing loss in their newborn baby. Parental wellbeing is of particular concern as the diagnosis occurs in the context of recovery from birth and at a time when the parent-child relationship is being established. As the vast majority of children with a hearing loss are born into hearing families with no prior history of deafness, parents generally have had little exposure to childhood hearing loss and often experience acute emotional vulnerability as they respond to the diagnosis. The researcher conducted in-depth interviews primarily with parents (and to a lesser extent with professionals), as well as a follow-up postal questionnaire for parents. Through a grounded theory analysis of data, the researcher subsequently fashioned a four-stage model depicting the parental journey of receiving and coping with a diagnosis. The four stages (entitled Anticipating, Confirming, Adjusting and Normalising) are differentiated by the chronology of service intervention and defined by the overarching parental experience. Far from representing a homogenous trajectory, this four-stage model is multifaceted and captures a wide diversity of parental experiences ranging from acute distress to resilient hopefulness

THE EFFECT OF A PROGRAM OF PORTABLE ELECTRONIC PIANO KEYBOARD EXPERIENCE ON THE ACQUISITION OF SIGHT-SINGING SKILL IN THE NOVICE HIGH SCHOOL CHORUS

The problem was to determine whether a method of aural and visual vocal training that included a program of portable electronic piano keyboard experience would be more effective in teaching sight-singing skills to novice high school chorus students than a method that included only aural and visual vocal training. A sub-problem was to determine whether novice chorus students enjoyed playing electronic keyboards in chorus as a reinforcement experience in sight-singing training. Students were randomly assigned to two treatment groups, tested with the Musical Aptitude Profile, Tonal Imagery, part A, and then trained separately. The experimental group sang repetitions of melodic patterns and utilized techniques associated with the Kodály Method while simultaneously playing keyboard. The comparison group received a similar treatment without using keyboards. The students were pre- and post-tested in sight-singing using the Vocal Sight-Reading Inventory. Results of the Analysis of Covariance using MAP scores as the covariate revealed no significant difference (p<.05) between post-test scores of the two groups. Improvement was noted in 96% of students from pre-test to post-test regardless of grouping. The repeated measures ANOVA revealed a significant relationship (p<.006) between aptitude group and post-test score. High aptitude students in both groups were found to benefit more from the training than low aptitude students. High aptitude keyboard group students achieved an average gain score that was 8.67 points higher than the comparison group. Of the total experimental group, 92% enjoyed playing keyboards in chorus. It is recommended that future research be undertaken to study the use of keyboards with advanced high school choruses and with uncertain singers in the high school chorus. Research is also needed to develop graded, valid, and reliable sight-singing tests for use in high school chorus. Techniques of the Kodály Method should be further investigated for use in high school sight-singing training.

Functional imaging of numerical processing in adults and 4-y-old children.

Adult humans, infants, pre-school children, and non-human animals appear to share a system of approximate numerical processing for non-symbolic stimuli such as arrays of dots or sequences of tones. Behavioral studies of adult humans implicate a link between these non-symbolic numerical abilities and symbolic numerical processing (e.g., similar distance effects in accuracy and reaction-time for arrays of dots and Arabic numerals). However, neuroimaging studies have remained inconclusive on the neural basis of this link. The intraparietal sulcus (IPS) is known to respond selectively to symbolic numerical stimuli such as Arabic numerals. Recent studies, however, have arrived at conflicting conclusions regarding the role of the IPS in processing non-symbolic, numerosity arrays in adulthood, and very little is known about the brain basis of numerical processing early in development. Addressing the question of whether there is an early-developing neural basis for abstract numerical processing is essential for understanding the cognitive origins of our uniquely human capacity for math and science. Using functional magnetic resonance imaging (fMRI) at 4-Tesla and an event-related fMRI adaptation paradigm, we found that adults showed a greater IPS response to visual arrays that deviated from standard stimuli in their number of elements, than to stimuli that deviated in local element shape. These results support previous claims that there is a neurophysiological link between non-symbolic and symbolic numerical processing in adulthood. In parallel, we tested 4-y-old children with the same fMRI adaptation paradigm as adults to determine whether the neural locus of non-symbolic numerical activity in adults shows continuity in function over development. We found that the IPS responded to numerical deviants similarly in 4-y-old children and adults. To our knowledge, this is the first evidence that the neural locus of adult numerical cognition takes form early in development, prior to sophisticated symbolic numerical experience. More broadly, this is also, to our knowledge, the first cognitive fMRI study to test healthy children as young as 4 y, providing new insights into the neurophysiology of human cognitive development.

Ritualizing Barong and Rangda: Repercussions of a Collaborative Field Experience in Kerambitan, Bali.

The dance-drama called Barong and Rangda a ritual, is one of the vital events that breathes life in the small village, Banjar Tista, and extends beyond the boundaries of its "performance" area. In this thesis, I depend on Ronald Grimes' concept of "ritualizing" as a continuum in the context of my fieldwork in Bali, Indonesia. The ritual cycle and the collaborative fieldwork process are analyzed through the impressions of each fieldworker. Barong and Rangda is a well-documented dance-drama and part of the longer Calonarang story. This dance-drama is a mythological battle between the lion, Barong, and the witch, Rangda, and is performed authentically to create spiritual balance and cleanse its community members of evil. This ritual performance reaches beyond the time and place in which the performance originates and creates a ripple affect on the village members, those in trance, musicians and cultural outsiders alike.

High School Choral Students' Perceptions of Choral Music Experience

The purpose of this study is to explore high school students' perceptions of their choral experiences, providing an understanding of students' ongoing perspectives of choral experience. Specifically, how have these experiences influenced the formation of their musical identities as members of a choral ensemble? The researcher collected data from the three participants during a full school year. The participants were current students in the researcher's advanced choral ensemble. Through axial coding, three themes emerged: musical interpretation, attitude, and group efficacy. The study revealed that experienced choral students have well-informed musical perspectives that influence their choral experiences. Implications for music education include using students' perspectives for creating rehearsal strategies, planning and programming performances, and fostering a nurturing learning atmosphere. Suggestions for further research include comparing experienced students to non-experienced students, comparing ensembles with student-chosen repertoire to those with director-chosen repertoire, and further examining the impact of choral experience on musical identity.

Emotional intensity predicts autobiographical memory experience.

College students generated autobiographical memories from distinct emotional categories that varied in valence (positive vs. negative) and intensity (high vs. low). They then rated various perceptual, cognitive, and emotional properties for each memory. The distribution of these emotional memories favored a vector model over a circumplex model. For memories of all specific emotions, intensity accounted for significantly more variance in autobiographical memory characteristics than did valence or age of the memory. In two additional experiments, we examined multiple memories of emotions of high intensity and positive or negative valence and of positive valence and high or low intensity. Intensity was a more consistent predictor of autobiographical memory properties than was valence or the age of the memory in these experiments as well. The general effects of emotion on autobiographical memory properties are due primarily to intensity differences in emotional experience, not to benefits or detriments associated with a specific valence.

Knowledge and judgments about events that occurred prior to birth: The measurement of the persistence of information

Data from five laboratories using five different techniques were reanalyzed to measure subjects' knowledge of events that occurred over the past 70 years. Subjects were about 20 years of age, so the measures included events that extended up to 50 years before birth. The functions relating knowledge about the events to age do not decrease precipitously at birth but gradually drop to above-chance levels. Techniques usually used to study retention within the individual can be used to study the persistence of ideas and fashions within an age cohort in a culture.

Smartphone ECG for evaluation of STEMI: Results of the ST LEUIS Pilot Study

© 2015 Elsevier Inc. All rights reserved.Background 12-lead ECG is a critical component of initial evaluation of cardiac ischemia, but has traditionally been limited to large, dedicated equipment in medical care environments. Smartphones provide a potential alternative platform for the extension of ECG to new care settings and to improve timeliness of care. Objective To gain experience with smartphone electrocardiography prior to designing a larger multicenter study evaluating standard 12-lead ECG compared to smartphone ECG. Methods 6 patients for whom the hospital STEMI protocol was activated were evaluated with traditional 12-lead ECG followed immediately by a smartphone ECG using right (VnR) and left (VnL) limb leads for precordial grounding. The AliveCor™ Heart Monitor was utilized for this study. All tracings were taken prior to catheterization or immediately after revascularization while still in the catheterization laboratory. Results The smartphone ECG had excellent correlation with the gold standard 12-lead ECG in all patients. Four out of six tracings were judged to meet STEMI criteria on both modalities as determined by three experienced cardiologists, and in the remaining two, consensus indicated a non-STEMI ECG diagnosis. No significant difference was noted between VnR and VnL. Conclusions Smartphone based electrocardiography is a promising, developing technology intended to increase availability and speed of electrocardiographic evaluation. This study confirmed the potential of a smartphone ECG for evaluation of acute ischemia and the feasibility of studying this technology further to define the diagnostic accuracy, limitations and appropriate use of this new technology.
