Less Talk, More Action: Ending the Futile Debate on a Canadian Securities Regulation to Focus on Resolving the Real IssuesPiane, Samantha 09 December 2013 (has links)
It has been endlessly demonstrated that the provinces will stand in the way of successful negotiations towards a common or national securities regulator in Canada. While there are many flaws in the current regulatory system, there are aspects of a decentralized model that can be valuable, particularly in a country with such regional diversity. Moving forward, policy development should focus on strengthening the current system while realizing the political realities that persist. By retaining various aspects of a decentralized model, yet also cooperating with the federal government to overcome issues that a national regulator might have resolved, there is potential for Canada’s system to prevail.

CAUSAL UNCERTAINTY AND SELF-REGULATION ABILITIESPASSEY, JENNIFER 03 September 2009 (has links)
Causal uncertainty refers to the lack of confidence in one’s ability to understand causal relations in the social world (Weary & Edwards, 1994). Relative to people with low causal uncertainty, individuals with high causal uncertainty exhibit enhanced self-regulation performance following a social interaction (Jacobson, Papile, Passey, & Boucher, 2006). The current studies investigated the potential mechanisms underlying this relationship, and the role of self-esteem.
Study 1 investigated whether the social or nonsocial nature of the depleting task and expectations about the need for future self-control could account for the relationship between causal uncertainty and self-regulation (N = 181). For the social task, high causally uncertain participants’ self-regulation performance was consistent across expectations for future self-control regardless of participant self-esteem. In contrast, low causally uncertain participants’ performance improved with increasing instructions to conserve energy for future tasks but only for participants with lower self-esteem. For low causally uncertain participants with higher self-esteem, self-regulation performance decreased with increased expectations for future self-control.
In the nonsocial condition, the findings did not differ by self-esteem. Learning that the future task involved self-control and that the initial task was depleting were both associated with increases in self-regulation for high causally uncertain participants. In contrast, self-regulation abilities did not differ for low causally uncertain participants upon learning that the future task involved self-control and marginally decreased when they learned that the initial task was depleting.
Study 2 examined whether or not self-presentation could account for the relationship between causal uncertainty and self-regulation abilities (N = 88). Higher causal uncertainty was associated with better self-regulation performance, but self-presentation goals did not moderate this relationship. Self-esteem did not influence self-regulation performance in this study.
Study 3 investigated whether or not an accuracy goal could account for the relationship between causal uncertainty and self-regulation abilities (N = 112). For participants with lower self-esteem, high causally uncertain participants’ self-regulation performance was consistent regardless of the goal manipulation; whereas low causally uncertain participants’ performance improved with instructions to create accurate impressions of their partner. In contrast, for participants with higher self-esteem, self-regulation did not differ by causal uncertainty or goal conditions. / Thesis (Ph.D, Psychology) -- Queen's University, 2009-08-28 14:40:08.139

Neurohumoral regulation of adrenal ornithine decarboxylase activityAlamzàn, Guillermina. January 1982 (has links)
The aim of this study has been to elucidate the neural pathways involved in the regulation of adrenal ornithine decarboxylase (ODC) activity. Administration of the dopamine-receptor agonists apomorphine (APM) and piribedil (PBD) to rats led to an increase in ODC activity of both the adrenal medulla and cortex. These effects were blocked by giving the animals the dopaminergic antagonist haloperidol. The APM-induced increase in adrenomedullary ODC activity was largely prevented by denervation of the adrenal, transection of the spinal cord, and transection of the mesencephalon-diencephalon. Section of ventral spinal roots reduced the induction to varying extents, depending on the number of roots cut and their location between T(,4) and T(,12). The inducing effect of APM on adrenocortical ODC was abolished by hypophysectomy. Splanchnicotomy, rhizotomy and bilateral adrenal demedullation each attenuated the action of the drug. In contrast to this, section of the spinal cord or surgical isolation of the hypothalamus (preparation of "hypothalamic island") potentiated its effect. Impairment of serotonergic nerve function by systemic administration of p-chlorophenylalanine and intraventricular injection of 5,6'-dihydroxytryptamine or electrolytic potentiated the effect of APM in the adrenal medulla, but reduced it in the cortex. These observations suggest that adrenal ODC activity is predominantly regulated by one or more central facilitatory dopaminergic pathways. The pathway for the regulation of the medullary enzyme involves nuclei in the diencephalon-telencephalon and ultimately acts through the sympathetic nervous sytem. The pathway for the cortex involves the hypothalamus and acts via the anterior pituitary gland. These pathways include serotonergic components, which have opposite net effects on the induction of ODC produced by APM: inhibitory for the medulla and facilitatory for the cortex.

Mechanisms of Inhibitory Synaptic Plasticity: The Regulation of KCC2Acton, Brooke Ashley 08 January 2014 (has links)
The mechanisms that regulate the activity of the neuron specific K+Cl- cotransporter (KCC2) remain poorly understood, despite the critical importance of this transporter in inhibitory synaptic transmission and plasticity. In this thesis I made three novel discoveries which reveal the cellular and molecular mechanisms of KCC2 regulation. First, I assayed the K+Cl- cotransport function of KCC2 under isotonic conditions and determined the molecular domain of the cotransporter required for constitutive Cl- transport in hippocampal neurons (Acton et al 2012). Specifically, I identified the 15 amino acid domain of the C-terminus in neurons that is responsible for the ability of KCC2 to cotransport K+Cl- under basal isotonic conditions, allowing it to remain constitutively active to create the steep Cl- gradient across the neuronal membrane required for synaptic inhibition. Secondly, I investigated a novel KCC2-interacting protein named Neto2 and determined its effect on the postsynaptic action of GABA (Ivakine et al 2013). I have found that Neto2, which is also an auxiliary protein of kainate-type ionotropic receptors, can also regulate the activity of the KCC2. Neto2 is required for neurons to maintain low [Cl-]i and strong synaptic inhibition. Third, I examined the functional relevance of the KCC2:Neto2:KAR multiprotein complex and found that this complex regulates the surface level
membrane expression pattern of KCC2 and the stability of the cotransporter in the membrane. Moreover, I have provided the first evidence that the interactions of KCC2:Neto2:GluK2 regulate KCC2 via a PKC-mediated phosphorylation of the cotransporter. Taken together, these results resolve three novel mechanisms of KCC2 regulation: the identity of the key C-terminal domain of KCC2 required for isotonic transport, the functional significance of the KCC2:Neto2 interaction, and the mechanism by which the KCC2:Neto2:KAR complex regulates KCC2 expression and mobility in the neuronal membrane.

Regulation of Midwifery in Puerto RicoCaban, Liani 21 November 2013 (has links)
Scholars and midwives agree that women’s autonomy over decisions related to birth is not being respected in a country where there is mainly one birth setting and one type of provider, in particular, when this setting and provider are often link to the use of unnecessary and excessive medical interventions. This is the case of Puerto Rico. I argue that midwifery could be an answer to this problem. Midwifery in Puerto Rico is not yet regulated, but I claim that in order to promote Puerto Rican women’s autonomy, midwifery regulation has to be well thought. This thesis includes an analysis of a bill proposed in Puerto Rico that pretended to regulate midwifery. Submissions presented to the legislature are also analyzed and criticized in this thesis. Some recommendations are provided on how Puerto Rico can enact a sensible scheme of midwifery regulation that would enhance midwives autonomy and therefore women’s autonomy.

The effect of music type on emotion regulation: An emotional-Stroop experimentFreggens, Marjorie 17 December 2014 (has links)
Introduction: Emotion regulation, the process of changing one’s emotion is necessary for efficiency when performing cognitive tasks, and is often measured using a Stroop task that provides conflict between emotional and factual information. Researchers have found that listening to music increases performance on cognitive tasks, and we hypothesize that listening to music samples that evoke different arousal and valence levels will affect participants’ emotion regulation skills. Method: 38 Georgia State University undergraduates listened to three-minute excerpts of film scores known to evoke a particular mood and arousal state while completing an emotional-Stroop task. Results: We performed a repeated measures ANOVA and found a significant difference of music type and an interaction between music type and word context. Discussion: These results provide evidence that music evokes different arousal and valence states, which have a distinct effect on emotion regulation skills.
