The goal of this thesis is to develop a set of tools for continuous tracking of behavioral phenomena in videos to support human behavior study. Current standard practices for extracting useful behavioral information from a video are typically difficult to replicate and require a lot of human time. For example, extensive training is typically required for a human coder to reliably code a particular behavior/interaction. Also, manual coding typically takes a lot more time than the actual length of the video (e.g. , it can take up to 6 times the actual length of the video to do human-assisted single object tracking. The time intensive nature of this process (due to the need to train expert and manual coding) puts a strong burden on the research process. In fact, it is not uncommon for an institution that heavily uses videos for behavioral research to have a massive backlog of unprocessed video data. To address this issue, I have developed an efficient behavior retrieval and interactive tracking system. These tools allow behavioral researchers/clinicians to more easily extract relevant behavioral information, and more objectively analyze behavioral data from videos. I have demonstrated that my behavior retrieval system achieves state-of-the-art performance for retrieving stereotypical behaviors of individuals with autism in a real-world video data captured in a classroom setting. I have also demonstrated that my interactive tracking system is able to produce high-precision tracking results with less human effort compared to the state-of-the-art. I further show that by leveraging the tracking results, we can extract an objective measure based on proximity between people that is useful for analyzing certain social interactions. I validated this new measure by showing that we can use it to predict qualitative expert ratings in the Strange Situation (a procedure for studying infant attachment security), a quantity that is difficult to obtain due to the difficulty in training the human expert.

Self-compassion is increasingly recognised as beneficial in psychotherapy, but can also be experienced as threatening. Attachment priming has been shown to enhance affiliative behaviours even in those with insecure trait attachment styles, and to decrease arousal and threat sensitivity. The current study investigated (a) associations between self-criticism, self-compassion, fear of self-compassion and trait attachment insecurity, and (b) whether attachment-related security priming could promote state self-compassion and reduce physiological arousal when self-compassion induction was attempted by self-critical individuals. 49 participants with high levels of self-reported self-criticism completed either a 'secure' or a 'neutral' prime before undertaking a loving-kindness meditation. Participants' heart rate and skin conductance levels were collected at baseline and during the priming and meditation; participants also self-rated their levels of state self-criticism, state self-compassion and state attachment security at each of these points. Correlational analyses (Spearman's rho) found positive associations between trait self-criticism and trait attachment insecurity and between trait fear of self-compassion and trait attachment insecurity, although not between low trait self-compassion and trait attachment insecurity. Group and time differences were analysed using a combination of parametric (ANOVA, t-test) and non-parametric tests (Mann-Whitney U-test, Kruskal Wallis, Wilcoxon Signed Rank) as some data were not normally distributed). Attachment priming was shown to significantly enhance state self-compassion and also to significantly increase state attachment security and decrease state attachment avoidance, although not state self-criticism or state attachment anxiety, and to give some reductions in physiological arousal. This benefit, however, did not persist in subsequent exposure to loving-kindness meditation, although individuals not receiving attachment priming also showed some reduction of threat and activation of soothing systems from loving-kindness meditation. These findings suggest that attachment priming and loving-kindness meditation may increase self-compassion for some self-critical people, but there are not necessarily cumulative benefits from combining these practices.

Dating violence (DV) is a common experience among college-age Canadians, affecting between one quarter and one third of both men and women. A significant predictor of DV perpetration and victimization is childhood physical abuse (CPA). While there is evidence of an intergenerational transmission of violence from CPA to both victimization and perpetration of DV in young adulthood, there remain gaps in our understanding of what factors influence these relationships throughout an individual’s development. Using survey data collected from a convenience sample of 660 University of Manitoba students, this study analyzed the strength of a model of violence development from CPA to DV including the mediating effects of personality symptoms and attachment security. The current study suggested partial support for theoretical frameworks that have been applied to the understanding of the relationship between CPA and DV, namely social learning theory, the criminological framework, and attachment based theories. CPA was correlated with DV perpetration and victimization. However, in multivariate analyses, witnessing interparental violence, rather than experiencing CPA, was a direct predictor of DV perpetration and victimization. CPA predicted DV indirectly through witnessing interparental violence. More severe dating violence items were significantly predicted by other variables in the model. Antisocial personality symptoms increased odds of severe DV perpetration and victimization while borderline personality symptoms increased odds of severe DV victimization. Attachment insecurity had the strongest impact on dating violence perpetration in the female subsample. These findings, suggesting a number of distinct pathways in the intergenerational transmission of violence, should be further tested in larger and more diverse samples. It would be beneficial to include additional risk and protective variables in future research in order to understand what impacts each distinct pathway to dating violence, under what circumstances, as well as the influence of these variables at different points in individuals’ development. This research is valuable for understanding the impact of childhood abuse on young adult attachment, personality, and dating violence. Further, it is hoped that this research will be helpful for establishing appropriate and comprehensive DV interventions which take into account mediating influences from the intergenerational transmission of violence.

Perceiving shared power in marriage has been linked to higher marital quality and lower attachment insecurity. Yet limited research has examined whether perception of power has a longitudinal influence on how both spouses' perceptions play a role in both spouses' outcomes. To address previous limitations, I utilized 319 couples (94.7% retention from Wave 1) from the Flourishing Families Project to estimate bi-yearly (Waves 1, 3, and 5) and yearly (Waves 3-5) longitudinal actor-partner interdependence models. Reporting shared power in marriage was linked to the actors' higher marital quality and lower attachment insecurity over time (though less consistently for attachment insecurity). Longitudinal partner effects and indirect effects were also found from reports of shared marital power to both marital quality and attachment insecurity over time. Little evidence was found for bidirectionality. The combined evidence suggests that power dynamics in a marriage are an important predictor of couples' overall relational well-being, and not simply a byproduct of other well-being indicators. Husbands and wives should mutually seek to help each other feel empowered in a relationship to reap the benefits of marital quality and secure attachment.

This study attempted to investigate father attachment using the dual primary attachment figure model by examining caregiving and exploration behaviors of mothers and fathers as they relate to attachment security utilizing an archival data set of 177 young adult females. A subsequent factor analysis of the involvement scales revealed four distinct items creating the caregiving variables (one for mother and one for father) and six items creating the exploration variables. Results showed that mothers engaged in caregiving and exploration behaviors more than fathers, but their exploration predicted mother attachment more than caregiving. Fathers engaged in more caregiving than exploration, but it was their involvement in exploration that was more strongly related to father attachment. These findings, which provide partial support for the dual primary attachment figure model, suggest that father exploration is a cornerstone for the father-child attachment relationship, but also predictive of mother-child attachment. Future studies should include observational assessments of father attachment as well as exploration in current assessments of father attachment.

Research shows a strong association between attentional bias to threat and emotional regulation difficulties, specifically heightened activation of neural areas known to be involved in emotional processing (amygdala) in individuals who report post-traumatic stress symptoms. Theoretical and research evidence suggests that the enhancing of felt attachment security through security-priming may grant an individual access to effective emotion regulation strategies, which in turn may reduce attentional bias and associated abnormal neural activations. Trauma-survivors with elevated anxiety levels were randomised into an experimental group (secure attachment priming, n=16) where they were primed using positive attachment-related pictures, or a neutral control priming condition (n=18) where they viewed non attachment pictures of people. Participants then completed a dot-probe task to measure attentional bias to threat, and an emotionally threatening face-matching task to probe amygdala activation. No between groups differences were found on measures of attentional bias. Contrary to the hypothesis, participants in the security-priming group showed significantly greater amygdala activation in response to threatening faces. Attachment style was not found to moderate the impact of security-priming on attentional bias or neural activation. Interpersonal trauma experiences make up the majority of the study sample. The impact of this is considered in the context of short-term single exposure to explicit attachment based security-priming interventions and the study paradigm employed to measure amygdala activation, which may act to initially dysregulate and contraindicate activation of a secure attachment representation, respectively.

93 Abstract Preliminary injunction is one of the most important means of protecting the rights of the participants of civil proceedings. The proceedings on the preliminary injunction is easier and faster than the proceedings on the merits, which allows the courts to act without undue delays and to effectively secure either the legal relations of the parties or the risk of loss. The consequence of these facts, however, is a restriction on the application of certain principles of civil procedure, and therefore also of the rights of the parties, especially the defendant. The question is whether this restriction is not unreasonably high and thus whether the current legal regulations meet requirements that are placed on it. The aim of this thesis is to provide a critical look at the regulation of preliminary injunctions, especially on its possibilities and limits, regarding the doctrinal and judicial conclusions. The first part of this thesis deals with the regulation of preliminary injunctions in general. Preliminary injunctions are there defined in terms of their meaning and the purpose, then the author briefly describes the basic principles, the taxonomy and the history of the regulation. The second and the third part focus on the material and formal conditions of the preliminary injunction. In addition to...
