abstract: Intimate coupling of Ti2 photocatalysis and biodegradation (ICPB) offers potential for degrading biorecalcitrant and toxic organic compounds much better than possible with conventional wastewater treatments. This study reports on using a novel sponge-type, Ti2-coated biofilm carrier that shows significant adherence of Ti2 to its exterior and the ability to accumulate biomass in its interior (protected from UV light and free radicals). First, this carrier was tested for ICPB in a continuous-flow photocatalytic circulating-bed biofilm reactor (PCBBR) to mineralize biorecalcitrant organic: 2,4,5-trichlorophenol (TCP). Four mechanisms possibly acting of ICPB were tested separately: TCP adsorption, UV photolysis/photocatalysis, and biodegradation. The carrier exhibited strong TCP adsorption, while photolysis was negligible. Photocatalysis produced TCP-degradation products that could be mineralized and the strong adsorption of TCP to the carrier enhanced biodegradation by relieving toxicity. Validating the ICPB concept, biofilm was protected inside the carriers from UV light and free radicals. ICPB significantly lowered the diversity of the bacterial community, but five genera known to biodegrade chlorinated phenols were markedly enriched. Secondly, decolorization and mineralization of reactive dyes by ICPB were investigated on a refined Ti2-coated biofilm carrier in a PCBBR. Two typical reactive dyes: Reactive Black 5 (RB5) and Reactive Yellow 86 (RY86), showed similar first-order kinetics when being photocatalytically decolorized at low pH (~4-5), which was inhibited at neutral pH in the presence of phosphate or carbonate buffer, presumably due to electrostatic repulsion from negatively charged surface sites on Ti2, radical scavenging by phosphate or carbonate, or both. In the PCBBR, photocatalysis alone with Ti2-coated carriers could remove RB5 and COD by 97% and 47%, respectively. Addition of biofilm inside macroporous carriers maintained a similar RB5 removal efficiency, but COD removal increased to 65%, which is evidence of ICPB despite the low pH. A proposed ICPB pathway for RB5 suggests that a major intermediate, a naphthol derivative, was responsible for most of the residual COD. Finally, three low-temperature sintering methods, called O, D and DN, were compared based on photocatalytic efficiency and Ti2 adherence. The DN method had the best Ti2-coating properties and was a successful carrier for ICPB of RB5 in a PCBBR. / Dissertation/Thesis / M.S. Biological Design 2011

The primary purpose of this study was to explore how intimate partner conflict changes over time. Patterns of conflict were explored based on the presence of substance use, name calling/threats, physical violence, jealousy, and conflict topic. Groups, or classes of couples, were identified based on conflict patterns. Next, the effects of the covariates on group membership were examined. Age, relationship length, intimate partner violence, substance use, and depression were investigated as covariates. Participants in this study included young couples from the Oregon Youth Study-Couples Study that included men who were at risk for delinquency and their women partners. The men and their partners were assessed at three waves between the ages of 25 and 31. Proximal contextual aspects of conflict, including substance use, threats and yelling, physical violence, and jealousy, were explored at three time points. Results suggest that conflict patterns change over time based on age and stage of relationship. Further, conflict patterns differ for men and women and the covariates predicted classes for men but were not predictive for women.

This dissertation examines the role of US legal and administrative institutions in intimate partner violence (IPV) against immigrant women in two instances treated as separate in policy and scholarship: 1) women seeking asylum in the US on account of IPV and 2) immigrant women facing IPV in the US. Through an analysis of congressional hearings, relevant policies and administration, court cases, and interviews with employees at non-governmental organizations that serve immigrant women, this dissertation analyzes the ways in which immigration law intersects with ameliorative policy intended to address IPV in these contexts. In so doing, I develop a broader understanding of how state institutions, policy frameworks, and policy implementation shape the lives of vulnerable immigrant women. Contrary to scholarship that views relevant policies and institutions in the US as well-meaning though inadequate, this dissertation examines the extent to which the state may be directly implicated in IPV against immigrant women and in fostering institutional conditions under which this violence continues to thrive.

abstract: Humans are social beings, which means interpersonal relationships are important contributors to our psychological health. Our health and behavior is manifested through a dynamic cycle of interacting factors: environmental, personal, and behavioral. Contributing to this interaction, interpersonal relationships provide benefits such as increased social support and decreased loneliness. The care and attention of relationship partners are communicated in multiple ways, one of which is interpersonal touch. Although touch can communicate positive feelings and support, it can also be used negatively in certain contexts. Unwanted or forced touch occurs when an individual experiences sexual or physical trauma. Experiencing this type of trauma often results in negative psychological consequences. Exactly how sexual or physical trauma—both of which involve unwanted touch—might influence an individual’s attitudes towards touch is important to explore. If an individual feels negatively about interpersonal touch due to previous experience of trauma, this might negatively influence the amount of current touch with a partner, and also the survivor’s psychological well-being. In the current study, I proposed that previous occurrence of sexual or physical trauma would predict both decreased frequency of touch in a current intimate relationship and poorer individual well-being, and that these relations would be explained by negative touch attitudes. Results supported these hypotheses, suggesting that lingering negative touch attitudes following trauma could be an underlying mechanism affecting social and individual functioning. As seen in our model, these attitudes fully mediated the effects between previous sexual or physical trauma and individual well-being, as well as frequency of touch. This understanding can help provide further insight into the repercussions of trauma and the underlying mechanisms attributing to continued negative effects. / Dissertation/Thesis / Masters Thesis Psychology 2018

In my dissertation, I use multi-ethnographic methods to examine how mediators talk about, manage, and process families going through divorce. I show how a dominant narrative about marriage and the cultural expectations of parenthood provide a framework for mediators to manage the discourse of divorcing parties so assets and care giving can be split 50/50. The dominant P.E.A.C.E. narrative (P=parenting plan, E=equitable distribution, A=alimony, C=child support, E=everything else) restricts available discourse in mediation and guides mediators’ behaviors in ways that homogenize families by providing a linear formula for mediators to follow which results in only certain stories being allowed to enter the mediation. Next, I show how constructions about power and violence serve to frame and shape understandings of divorce for mediators, thereby guiding their actions in mediation and discursively impacting the discourses of mediated parties. Power and violence are constructed in ways that conflate the concepts, and no clear protocol is offered to manage these complicated concerns for family law mediators. The outcome is mediators report being unsure and often fearful about mediating cases where intimate partner violence is a concern. Finally, an analytic autoethnographic examination of family law mediation provides an example of the power of ideology and makes clear my positionality within this dissertation. I explore my own identity as a white, heterosexual, female, in a world ripe with expectations about marriage and family creation as I encounter alternative messages and information in my fieldwork. Throughout my dissertation, I uncover larger cultural narratives about marriage, and families that guide and manage people, illustrating the ways identities, stories of violence, and the ideology of marriage are shaped.

Wikstrӧm’s Situational Action Theory (SAT) proposes a general theory of crime causation that addresses two sets of interactions between individuals and their situation/environment. These interactions predict whether or not individuals choose a criminal action. The current study utilized self-report data on intimate partner violence collected at a large urban university in Florida (n=1124) to test this process by examining both direct and interactive effects proposed by the theory. Specifically, this study examines the direct effects of moral propensity, temptations/provocations, self-control and perpetual deterrence on intimate partner violence as well as the various interactions among them as derived from the theory. This study is the first complete test of SAT to date.

M.A. / Domestic abuse is a global and growing problem (World Health Organization WHO, 2002). The extent and magnitude, as well as effects of domestic abuse are, however, underreported especially within South Africa (Prinsloo, 2007). Awareness has been raised by initiatives such as Sixteen Days of Activism on Violence Against Women campaigns driven by POWA (People Opposed to Women Abuse), yet the rates of abuse stay alarming. In light of the occurrence of abuse as well as the limited resources available, some women kill an intimate partner after a prolonged period of abuse. The specific aim of the study was to uncover the psychological factors that contribute or are associated with the killing of an abusive partner by women. This was done by using multiple case studies and unstructured interviews. Participants were sourced from the Department of Correctional Service in the Western Cape Province. The participants utilised for the research included three women who killed their abusive intimate partner, and who were incarcerated at Pollsmoor Correctional Facility at the time of the interview. In-depth interviews were conducted and the data was analysed in order to derive themes. Once the themes were established, results were compared to relevant research in the field as a means to establish the psychological factors associated with women who kill an abusive intimate male partner. 5 The results indicated that certain primary psychological factors present in the sample group of interviewed women namely: development of Post Traumatic Stress Disorder, experiences of coercive control, interrelational conflict and substance abuse. Secondary themes or factors found included cultural perceptions and a lack of resources. From the results obtained, a conclusion was made that women who kill an abusive intimate male partner, are often compelled to do so due to underlying factors and as a means of survival. Furthermore, culture appears to have a prominent influence as it informs the manner and acceptable means to deal with domestic abuse. Although the research contributes to the pool of knowledge regarding women who kill an abusive intimate male partner in South Africa, more is needed especially in the development of intervention programs and support.

Non-suicidal self-injury (referred to hereafter as self-injury) is considered a serious health concern among young adult populations, and is associated with a host of devastating physical and psychological consequences (Hasking, Momeni, Swannell, & Chia, 2008). Self-injury encompasses both thoughts of harming oneself in addition to acts of self-injury. Elevated lifetime prevalence rates of 13-17% suggest that self-injury is an issue of widespread nature, with reports indicating that a considerable proportion of young adults engage in self-injurious thoughts and behaviours (Nixon, Cloutier, & Jansson, 2008; Swannell, Martin, Page, Hasking, & St John, 2014; Whitlock, Eckenrode, & Silverman, 2006). Identifying the factors that precede self-injury is crucial to advancing current clinical conceptualizations and treatment strategies for those engaging in such thoughts and behaviours (Schenk, Noll, & Cassarly, 2010). Despite the recognized role of romantic relationship experiences in contributing to the functioning and adjustment of the individuals comprising the romantic dyad, very little empirical attention has been paid to examining whether dimensions of romantic relationships are linked to the use of self-injury. The present thesis, consisting of two independent studies, sought to provide a better understanding of the factors underlying this troubling phenomenon by examining links between dimensions of romantic relationships and self-injurious thoughts and behaviours among community-based young adults involved in couple relationships. The studies presented in the present thesis were approved by the University of Ottawa’s Research Ethics Board (see Appendix A for the Ethics Approval Certificate). The first study involved testing a novel conceptual model in which intimate partner violence victimization (i.e., physical, psychological, and sexual violence) was examined as a potential mediator of the relationship between child maltreatment (i.e., neglect; witnessing family violence; and physical, psychological, and sexual abuse) and self-injurious thoughts and behaviours. The sample consisted of 406 young adults (346 females; M = 19.87 years) who were involved in a couple relationship for a duration of at least six months at the time of participation. Results from bootstrapping procedures partially supported the theory put forth. Intimate partner violence victimization partially mediated the direct effect of child maltreatment on self-injurious behaviours. Contrary to predictions, intimate partner violence victimization did not mediate the association between child maltreatment and self-injurious thoughts. Hence, findings suggest that individuals who have experienced both forms of family violence may be particularly vulnerable to engaging in self-injurious behaviours. The second study comprised an investigation of the links between the three romantic behavioural systems (consisting of the attachment, caregiving, and sexual systems) and self-injurious thoughts and behaviours, and examined the incremental contributions of the systems in the prediction of young adult self-injury. The sample consisted of 255 young adults (223 females; Mage = 19.98 years) currently involved in a couple relationship. Linear discriminant analyses revealed that participants endorsing self-injurious thoughts experienced greater attachment anxiety and avoidance, controlling and compulsive romantic caregiving behaviours, and lower sexual satisfaction than did participants who did not endorse such thoughts. In contrast, findings indicated that the behavioural systems did not predict self-injurious behaviours. Such findings suggest that dimensions of the three interrelated behavioural systems hold unique roles in understanding young adult self-injurious thoughts, and that the constructs that predict self-injurious thoughts may differ from those that predict self-injurious behaviours.

Against the background of a history of apartheid and colonialism, high levels of unemployment, an established tradition of hegemonic masculinity, pervasive violence, especially gender-based violence, as well as some of the highest levels of inequality in the world, this mini-dissertation focuses on the accounts of a cross-class selection of African women who live in South Africa and who self-identify as being in a relationship with an abusive intimate partner. It is based on eight in depth interviews with women, many of whom are immigrants or migrants from elsewhere on the continent, and all of whom are either married or in long-term relationships with their partners and have children. The study focused on the factors that impacted on their decision to stay on in the abusive relationship as well as on their internal thoughts and how these illuminate their decision to stay. In particular, the study explores how to make sense of the notion of 'agency' when considering women who stay on in an abusive relationship, and draws on the work of Margaret Archer on reflexivity and internal thoughts, as distinct from and in addition to a Bourdieusian focus on habitus and a structural analysis of the social context in which the abuse takes place and of factors that impede participants’ ability to leave the abusive relationship. The study identifies the key factors women cite as playing a role in their decision to stay, namely fear of violence; a concern with providing a 'home' for children; cultural considerations and family pressures; and structural factors (finance, migration status, employment status and a lack of adequate support structures). In addition, one of the major contributions of this study is its focus on the participants' self-described internal thought processes to consider to what extent these processes could be described as demonstrative of or enabling 'agency' in difficult circumstances. / Mini-dissertation (MSocSci)--University of Pretoria, 2015. / tm2015 / Sociology / MSocSci / Unrestricted
