Parents of children with autism spectrum disorders (ASD) and developmental delays (DD) may experience more child problem behaviours, report lower parenting selfefficacy (PSE), and be more reactive than proactive in their parenting strategies than those who have children with typical development (TD). Differences in PSE and parenting strategies may also influence the extent to which child problem behaviours are experienced by parents who have children with ASD and DD, compared to those who have children with TD. Using a convenience sample of parents of children with ASD (n = 48), DD (n = 51), and TD (n = 72), this study examined group differences on three key variables: PSE, parenting strategies, and child problem behaviour. Results indicated that those in the DD group scored lower on PSE in preventing child problem behaviour than the ASD group. The TD group used fewer reactive strategies than the DD group, and fewer proactive strategies than both the ASD and DD groups. For the overall sample, higher reactive strategies use was found to predict higher ratings of child problem behaviour, while a greater proportion of proactive to reactive strategies use predicted lower ratings of child problem behaviour. PSE was found to moderate DD diagnosis and child problem behaviour. Implications for a behavioural (i.e., parenting strategies) or cognitive (i.e., PSE) approach to parenting are discussed.

The purpose of this study was to examine whether certain temperament characteristics (fearfulness, surgency, frustration, and effortful control) moderate the association between authoritative parenting dimensions (psychological autonomy granting, acceptance-involvement, and monitoring knowledge) or friends' antisocial behaviour, and self-reported antisocial behaviour among adolescents. Questionnaires on adolescent temperament and authoritative parenting were completed by 484 mothers and their adolescent children (54.8% female). In addition, the adolescents responded to measures regarding friends' antisocial behavior and their own antisocial behaviour. Adolescent participants ranged between 13 and 17 years of age (M = 14.96 years, SD = 1.39) and lived in a region of southern Ontario. As predicted, the results indicated that effortful control moderated the association between parental monitoring knowledge and adolescent antisocial behaviour. Also, as predicted, effortful control moderated the relation between friends' antisocial behaviour and adolescents' self-reports of antisocial behaviour although the relation was sex-specific to girls. Unexpected results included a significant monitoring knowledge by frustration by sex interaction, and a significant friends' antisocial behaviour by age interaction. In general, the findings were consistent with the expectation that the relation of parenting and peer factors to antisocial behaviour would depend on adolescents' temperamental predispositions. However, effortful control, which contributes to individual differences in self-regulation abilities, served this moderating role to a greater extent than the measures of temperamental reactivity, including fearfulness, surgency and frustration-proneness. Implications of these results are discussed with reference to parenting or classroom-based interventions that may be especially helpful for adolescents with poor self-regulation abilities.

This study investigated improvements in parent knowledge of effective intervention strategies following participation in a group function-based CBT treatment (GFbCBT) package for children with comorbid OCD and ASD. Nineteen parents of children ages 7-12 years with High Functioning Autism (HFA) participated in the 9-week treatment program. Key components of treatment included psychoeducation and mapping, cognitive-behavioural skills training, function-based interventions and exposure and response prevention (ERP). Treatment sessions also included direct parent education, which followed a behavioural skills training model (Miltenberger, 2008). Parent knowledge (N = 19) was measured pre and post treatment using a vignette about a child demonstrating obsessive-compulsive behaviour. Results of a one-tailed pairwise t-test indicated statistically significant changes (p=.036) in overall parent knowledge following participation in treatment. Statistically significant changes were also found in parents’ ability to generate ERP and function-based intervention strategies. These results provide preliminary evidence that parents benefit from active involvement in the GFbCBT treatment package.

Complex networks can arise naturally and spontaneously from all things that act as a part of a larger system. From the patterns of socialization between people to the way biological systems organize themselves, complex networks are ubiquitous, but are currently poorly understood. A number of algorithms, designed by humans, have been proposed to describe the organizational behaviour of real-world networks. Consequently, breakthroughs in genetics, medicine, epidemiology, neuroscience, telecommunications and the social sciences have recently resulted. The algorithms, called graph models, represent significant human effort. Deriving accurate graph models is non-trivial, time-intensive, challenging and may only yield useful results for very specific phenomena. An automated approach can greatly reduce the human effort required and if effective, provide a valuable tool for understanding the large decentralized systems of interrelated things around us. To the best of the author's knowledge this thesis proposes the first method for the automatic inference of graph models for complex networks with varied properties, with and without community structure. Furthermore, to the best of the author's knowledge it is the first application of genetic programming for the automatic inference of graph models. The system and methodology was tested against benchmark data, and was shown to be capable of reproducing close approximations to well-known algorithms designed by humans. Furthermore, when used to infer a model for real biological data the resulting model was more representative than models currently used in the literature.

When observing client behaviours, a therapeutic recreation specialist must have a base understanding of typical client behaviours to provide an informed analysis (burlingame & Blaschko, 2010). Providing students with the necessary tools for client observation is significant to the success of this process. The purpose of this study was to assess the relationships amongst the TR student demographic characteristics on acquiring the observation competency necessary to conduct a TR assessment. One hundred seventy-two TR college and university students, enrolled in post-secondary undergraduate TR programs across Ontario, observed a client assessment via video, and recorded their observations using the Tracking Behavioural Assessment (TBA) (Passmore, 2002). Independent samples t-tests and analysis of variance were calculated for the different student characteristics on the domains of the TBA. Significant findings indicated that university students scored more accurately than college students, and advanced students more accurately than novice students, on the emotional and socialization domains.

Self-efficacy (SE), a person’s confidence in the ability to perform a task, is an important predictor of the adoption and maintenance of physical activity. The present study examined the effects of SE manipulated through verbal persuasion on exercise intentions and behaviour during a 4-week follow-up period and investigated the role of social physique anxiety (SPA) as a moderator. Female college infrequent exercisers (n = 66) were randomly assigned into one of three groups (high-efficacy [HE], low-efficacy [LE], or control) and asked to complete several questionnaires at baseline. The HE and LE groups were provided with positive and negative exercise adherence feedback, respectively. The HE group reported higher SE from pre- to post-feedback. Both the HE and LE groups reported increases in exercise behaviour at the 4-week follow-up. Pre- to post-feedback changes in SE, exercise intention, and exercise behaviour did not depend on level of SPA reported.

Drawing from the Job Demands-Resources (JD-R) model and research on social exchange relationships, this study investigates the impact of three job demands (work overload, interpersonal conflict, and dissatisfaction with the organization’s current situation) on employees’ organizational citizenship behavior (OCB), the hitherto unexplored mediating role of organizational commitment in the link between job demands and organizational citizenship behavior (OCB), as well as how this mediating effect might be moderated by social interaction. Using a multi-source, two-wave research design, surveys were administered to 707 employees and their supervisors in a Mexican-based organization. The hypotheses were tested with hierarchical regression analysis. The results indicate a direct negative relationship between interpersonal conflict and OCB, and a mediating effect of organizational commitment for interpersonal conflict and dissatisfaction with the organization’s current situation. Further, social interaction moderates the mediating effect of organizational commitment for each of the three job demands such that the mediating effect is weaker at higher levels of social interaction. The study suggests that organizations aiming to instill OCB among their employees should match the immediate work context surrounding their task execution with an internal environment that promotes informal relationship building.

Recent research suggests organizational factors should be considered in order to better understand the attrition of minor hockey. Consequently, the purpose of this quantitative study was to examine the extent to which minor hockey officials perceive organizational support (POS) from the minor hockey system, and to compare POS among minor hockey officials according to demographics. A total of 261 minor hockey officials were surveyed with the Survey of Perceived Organizational Support (SPOS). Results indicated significant differences according minor hockey official experience, certification level and extra-role performance. The findings are discussed in relation to POS and human resource management literature, and recommendations are made as to how administrators can better support these officials.

In this thesis, I focus on supply chain risk related ambiguity, which represents the ambiguities firms exhibit in recognizing, assessing, and responding to supply chain disruptions. I, primarily, argue that ambiguities associated with recognizing and responding to supply chain risk are information gathering and processing problems. Guided by the theoretical perspective of bounded rationality, I propose a typology of supply chain risk related ambiguity with four distinct dimensions. I, also, argue that the major contributor to risk related ambiguity is often the environment, specifically the web of suppliers. Hence, I focus on the characteristics of these supplier networks to examine the sources of ambiguity. I define three distinct elements of network embeddedness – relational, structural, and positional embeddedness – and argue that the ambiguity faced by a firm in appropriately identifying the nature or impacts of major disruptions is a function of these network properties. Based on a survey of large North American manufacturing firms, I found that the extent of the relational ties a firm has and its position in the network are significantly related to supply chain risk related ambiguity. However, this study did not provide any significant support for the hypothesized relationship between structural embeddedness and ambiguity. My research contributes towards the study of supply chain disruptions by using the idea of bounded rationality to understand supply chain risk related ambiguity and by providing evidence that the structure of supply chain networks influences the organizational understanding of and responses to supply chain disruptions.

Through the reflective lens of an adult educator with invisible and episodic disabilities, this paper has been written as an organizational autoethnography. Through a process of autoethnographical sensemaking, it is intended to illuminate important gaps in organizational theory. Feminist/relational care ethics, critical reflection, and transformative learning serve as the educational theories that comprise its framework. In telling my story, embodied writing and performance narrative are used to convey the felt existence of a body exposed through words—where my “abled” and “disabled” professional teaching and learning identities may be studied against the backdrop of organizational policies and procedures. Words used to describe unfamiliar experiences and situations shape meaning for which new meaning may emerge. At the conclusion of this paper, an alternative frame of reference—a view from the margins—may be offered to articulate authenticity in the expectancy of workplace equity for adult educators with disabilities. Taken collectively on a larger level, it is hoped that this research may provide a source of inspiration for systemic organizational change in adult learning environments.

Psychopathy researchers have long debated the role of antisocial behaviour and criminality as part of the construct of psychopathy. The current study examined the relationship between the interpersonal and affective traits (Factor 1) of psychopathy and antisocial behaviour (a facet of Factor 2), examining possible predictors of antisocial behaviour. It was hypothesized that early environment would moderate the relationship between Factor 1 traits and antisocial behaviour. Hierarchical multiple regression analyses were used in order to test for possible moderators. Sex differences were found, where men scored higher in Antisocial Behaviour. Childhood Abuse did not moderate the relationship between Factor 1 traits and Antisocial Behaviour, but predicted higher Antisocial Behaviour scores independently. Maternal Neglect was especially influential as a risk factor, significantly interacting with Factor 1 traits to predict higher Antisocial Behaviour scores. Maternal Warmth was also important, interacting with Factor 1 in a protective fashion, predicting lower Antisocial Behaviour Scores.

This study contributes to current research on voice behaviour by investigating several under-explored drivers that motivate employees’ expression of constructive ideas about work-related issues. It draws from the concept of psychological climate to examine how voice behaviour is influenced by employees’ (1) personal resources (tenacity and passion for work), (2) perceptions of social interdependence (task and outcome interdependence), and (3) supervisor leadership style (transformational and transactional). Using a multi-source research design, surveys were administered to 226 employees and to 24 supervisors at a Canadian-based not-for-profit organization. The hypotheses are tested with hierarchical regression analysis. The results indicate that employees are more likely to engage in voice behaviour to the extent that they exhibit higher levels of passion for work. Further, their voice behaviour is lower to the extent that their supervisor adopts a transformational leadership style characterized by high performance expectations or a transactional leadership style based on contingent rewards and contingent punishment behaviours. The study reveals that there are no significant effects of tenacity, social interdependence, and behaviour-focused transformational leadership on voice. The findings have significant implications for organizations that seek to encourage employee behaviours that help improve current work practices or undo harmful situations.

Recent research in the marketing literature has indicated that, while consumers’ interests in ethical products are growing, demand for such products still remains weak. Previous research has indicated that anticipated guilt can have a positive effect on ethical consumption. Thus, the objective of the current study is to investigate the moderating role of consumers’ socially responsible consumption behaviour (SRCB) on the relationship between anticipated guilt and ethical consumption. Specifically, the current study hypothesizes that, when viewing a guilt ad, high (vs. low) SRCB individuals will generate higher, ethical purchase intentions, willingness to pay an ethical premium, and attitudes toward an ethical brand. The findings from the two experimental studies indicate that, when viewing a guilt ad for an ethical product, high SRCB individuals are willing to pay a higher ethical premium and generate more favourable brand attitudes than low SRCB individuals. However, when viewing a non-guilt ad, high SRCB individuals did not differ from low SRCB individuals in their willingness to pay an ethical premium or brand attitudes. Further, consumers’ socially conscious self-identity was explored as a mediator of these effects. By understanding the moderating role that SRCB plays in the relationship between anticipated guilt and ethical consumption, this paper intends to assist marketers in understanding for which consumers a guilt appeal is an appropriate strategy in marketing ethical products.

Children with Autism Spectrum Disorder (ASD) have restricted and repetitive behaviours (RRBs) which may be similar to obsessions and compulsions in Obsessive Compulsive Disorder (OCD). These behaviours can be intrusive and interfere in the lives of the child and their family. Preliminary studies have shown success in using adapted Cognitive Behavioural Therapy (CBT) to treat these behaviors in children with high functioning ASD. Using a hypothetical vignette, this thesis attempted to examine procedural knowledge that the children and their parents gained while participating in a CBT treatment that was evaluated in a Randomized Controlled Trial. For both parents and children, there was a significant increase in number of strategies generated from pre to post-treatment. Further, children in the experimental group generated significantly more strategies than the treatment as usual (TAU) group post-intervention. There was no significant correlation between number of strategies generated and the child’s treatment success, age, or IQ.

Sustainability of change for improvement initiatives has been widely reported as a global challenge both within and outside health care settings. The purpose of this study was to examine the extent to which factors related to staff training and involvement, staff behaviour, and clinical leaders’ and senior leaders’ engagement and support impact the long term sustainability of practice changes for BPSO health care organizations who have implemented Registered Nursing Association of Ontario’s (RNAO) Best Practice Guidelines. Semi structured interviews with eleven organizational leaders’ from ten health care organizations were conducted to explore the unique experiences, views and perspectives on factors related to staff, clinical leaders and senior leaders and their involvement and impact on the long term sustainability of clinical practice changes within organizations who had implemented Registered Nursing Association of Ontario’s (RNAO) Best Practice Guidelines (BPGs). The interviews were coded and analyzed using thematic content analysis. Further analysis identified patterns and themes in relation to: 1. The National Health Service (NHS) Sustainability Model which was used as the theoretical framework for this research; and 2. Organizations found to have sustained practice changes longer term verses organizations that did not. Six organizations were found to have sustained practice changes while the remaining four were found to have been unsuccessful in their efforts to sustain the changes. Five major findings in relation to sustainability emerged from this study. First is the importance of early and sustained engagement and frontline staff, managers, and clinical leaders in planning, implementation and ongoing development of BPGs through use of working groups and champions models. Second is the importance of ongoing provision of formal training, tools and resources to all key stakeholders during and after the implementation phase and efforts made to embed changes in current processes whenever possible to ensure sustainability. Third is to ensure staff and management are receptive to the proposed change(s) and/or have been given the necessary background information and rationale so they understand and can support the need for the change. Fourth is the need for early and sustained fiscal and human resources dedicated to supporting BPG implementation and the ongoing use of the BPGs already in place. Fifth is ensuring clinical leaders are trusted, influential, respected and seen as clinical resources by frontline staff. The significance of this study lies in a greater understanding of the influence and impact of factors related to staff on the long term sustainability of implemented practice changes within health care organizations. This study has implications for clinical practice, policy, education and research in relation to sustainability in health care.
