The mixed methods analysis of police and non-police shooters
Get PDFThe purpose of this mixed-methods research is to discover the common and differentiating factors between criminals who shoot at police or who shoot at others in Canada. This research collected secondary data from 52 participants. Two sample groups are the police shooters (shooters who target the police) and the general shooters (shooters who target nonpolice). Each sample group contained 26 participants from across Canada. Data was analyzed using a convergent, mixed methods approach. Both quantitative and qualitative factors were involved in the analysis. The research question of this study was, “How do characteristics vary for Canadian criminal shooters who target police compared to those who do not?” The characteristics are the identified past and present variables that may contribute to the criminal shooting. It was concluded that the police shooters and general shooters are similar, but they have some differences. There was a highly significant association between the police shooter and being arrested, there was a very significant association between the general shooter and the drug trade, and there was a marginally significant association between the police shooter and experiencing a traumatic event (in adulthood). The remaining variables discussed in this study were non-significant, but still relevant.criminal shooter; firearm crime; gun violence; police shooter; firearm
The effects of foam rolling vs massage guns vs dynamic stretching on trunk forward flexion
Get PDFMassage guns and other self administered massage tools such as the foam roller have grown in popularity. Are they as effective as they claim to be? How do they compare to dynamic stretching? Are they worth? Dynamic stretch routine, foam rolling and massage gun application all acutely improved sit-and-reach scores. Further investigation on long-term effects should be investigated further.

Pituitary adenylate cyclase-activating polypeptide receptor expression in sympathetic ganglia innervating adipose tissue
Get PDFObesity is a disease that occurs when energy intake exceeds energy expenditure, concomitantly increasing risk of chronic diseases, including metabolic diseases such as diabetes. Research into therapeutics to correct dysregulations in energy balance is on the rise, and one notable neuropeptide being studied is pituitary adenylate cyclase-activating polypeptide (PACAP). PACAP has been shown to regulate thermogenesis, an energy burning process regulated by the sympathetic nervous system (SNS) in response to cold stress and overfeeding, but its role within the sympathetic nerves innervating and regulating energy metabolism in adipose tissues is not well understood. We hypothesize that PACAP is acting on PACAP receptors (PAC1, VPAC1, VPAC2) expressed in stellate ganglia innervating brown adipose tissue, the main thermogenic organ in mammals. We have established a reliable protocol for the isolation of two ganglia of the SNS (stellate and superior cervical) and provided recommendations of reference genes to use as internal controls for gene expression studies. For the first time, we confirmed PACAP receptor gene expression in the stellate ganglia, and saw sex-specific, differential gene expression based on housing temperature. We subsequently analyzed the expression of PAC1 splice variants in the stellate ganglia and our positive control tissues (adrenal gland and superior cervical ganglia), identifying at least two variants in these SNS tissues. This work adds to current literature on the study of thermogenesis and energy balance, and encourages future work characterizing G-protein coupled receptors (GPCRs) for their therapeutic application, enhancing our fundamental understanding of autonomic physiology in mammals

The role of Big Data in humanitarian organisations in developing countries: A systematic literature review
Get PDFBeing financially and technologically worse off than their counterparts in developed nations, many developing countries face natural disasters that cut them off from the rest of the world and cause excessive damage to invaluable human life and property. Sudden disasters require timely and accurate response from stakeholders to provide immediate relief while deploying scarce resources effectively. However, due to the large number of humanitarian aid agencies from different developed countries and a lack of knowledge, there is duplication of relief in many areas while countless more are left unattended. In this thesis, Resource Dependence Theory and Stakeholder Theory were employed to analyse how humanitarian organisations deliver services during a disaster. Systematic literature review was utilised for collecting data and the data was analysed using thematic analysis. During the data collection process, 300 papers were initially identified however, after further reassessment, 33 papers were left to be further analyzed. From this the researcher was able to identify that the use of Big Data in developing countries is proving to be extremely beneficial to humanitarian efforts, according to this thesis. It also explains how humanitarian organizations can make better use of big data by overcoming obstacles. The thesis suggests that increasing the number of data scientists and specialists by conducting big data training for staff, improving data governance (regulations, controls, and transparency), and enhancing privacy and security will result in major improvements in humanitarian operations. Give the importance of private stakeholders, companies' roles extend far beyond delivering profits to their shareholders, they must also address social issues by participating in disaster and humanitarian operations in developing countries
Resource acquisition and allocation in mountain bluebirds (Sialia currucoides)
Get PDFThe strategic allocation of resources to maximize fitness is the organizing principle shaping the evolution of life histories. The physiology and behaviour of animals is a manifestation of trade-offs in resource allocation among traits and activities that benefit current or future reproduction. In theory, traits subject to such trade-offs are expected to show negative correlations, but numerous field studies have documented apparent contradictions to theoretical expectations: in some populations, parental effort (allocation to current reproduction) and reproductive performance (i.e., a fitness
component) are not negatively correlated to self-maintenance (allocation to future reproduction). One explanation for such findings is that inter-individual variation in resource acquisition can obscure trade-offs by altering the overall quantity of resources individuals are able to invest. Acquisition may influence both the quantity of resources allocated in trade-offs as well as reproductive success. Asymmetries in acquisition may be the product of differences in intrinsic quality (individual phenotypes) and/or environmental factors (territory quality). In a population of breeding mountain bluebirds
(Sialia currucoides), I sought to determine how resource acquisition varied, and to identify how it may affect life-history trade-offs and reproductive performance. In my research, I used several lines of inquiry to characterize how resource acquisition varies and affects trade-offs in the study population. First, I showed that offspring quality, a contributor to fitness, is influenced by the types of prey nestling bluebirds are fed by their parents, and that the resources parents provide to their broods vary seasonally and as their nestlings age. Next, I used a short-term manipulation of brood age to find that parents have limited flexibility in their capacity to acquire resources while provisioning broods, which may be due to intrinsic or extrinsic constraints. I then identified relationships among the landscape characteristics of breeding territories (extrinsic factors, potentially influencing acquisition) and the reproductive performance of bluebirds, over an 11-year period. These characteristics, elevation and distance to forest edges, are subsequently linked to differences in microclimate, microhabitat, and parental prey use, providing a partial explanation for why occupancy and reproductive success are spatially clustered and consistent over time. Finally, I used a brood size manipulation to induce changes in parental effort, revealing that acquisition (quantified as both individual and territory quality) influences how mountain bluebirds trade-off one proxy for self-maintenance (energy metabolites) with providing food to their offspring. Interestingly, these effects differed between the sexes. Females generally biased allocation towards current reproduction, increasing provisioning to larger broods, regardless of territory quality; females on low-quality territories subsidized increased
provisioning activity by catabolizing stored resources. In contrast, only males on high-quality territories increased parental effort in response to larger broods, and among these individuals, only high-quality males incurred an energy deficit to subsidize this activity. My findings showed that resource acquisition may be critical to understanding why trade-offs differ among individuals, and that both intrinsic and extrinsic limits on acquisition may influence the patterns of allocation we observe in wild populations
