Child protection : trends and issues in Alberta
The Honourable Iris Evans, Minister of Children's Services for Alberta, has stated that "Alberta's children deserve to be cherished and cared for in quality childcare settings that contribute to their social and personal development" (Government of Alberta, December 16, 2002). Fortunately, the majority of parents are raising their children in such environments. However, there are families who pose a risk to the safety and security of their children, and child protection services may be involved with these families. The Alberta Response Model is based on the assumption that families who come to the attention of the child protection system are currently handled in a manner that is intrusive and stigmatizing. Instead of being a helpful and proactive service, child protection can become detrimental and potentially harmful to the clientele it serves. The Alberta Response Model is a new departure in child welfare practice and provides an alternative approach. Each of the 18 regional Child and Family Service Authorities is to develop its own initiatives incorporating the activities and philosophy of the Alberta Response Model. In the southern Alberta region, Sun Country Child and Family Services provides child protection services and has developed many innovative and creative projects to keep children safe. This project examines the Alberta Response Model in four sections: the historical context, current practice, Sun Country's response, and concerns and dilemmas.
Behind the colonial wall: the chains that bind resistance
Supervisory Committee Dr. Catherine Richardson, School of Social Work Supervisor Dr. Jeannine Carriere, School of Social Work Departmental Member The “colonial wall” is the analogy drawn between a visible, physical barrier designed to confine, control, and contain a nation and a psychological barrier designed to control, confine, and contain a nation by internalized colonialist subjugation or colonizer domination. This thesis answers the question, “How are colonial policies and ideologies internalized by Indigenous and Settler populations to maintain the relationship of domination and oppression in modern society?” The secondary questions explore how colonialism is perpetuated by both colonizer and colonized and ask if there are situations occurring in society today to indicate a correlation to the Indigenous Seven Prophecies and Eighth Fire Prophecy. Research constitutes a review of literature to explore the questions from thematic categories that emerged from the analysis: economics, epistemology, politics, and patriarchy. There are numerous literary contributions on the colonial phenomenon but few offered explanations about how it affected the psychology of a colonized individual or even how cognitive function is affiliated with acts of domination that affect the psyche of the colonizer. This thesis documents and offers emerging theories on how colonial policies and practices are taken up to influence the dyadic relationship between Settler peoples and Aboriginal populations in Canada today.
Intensification of Bubble Disintegration and Dispersion by Mechanical Stirring in Gas Injection Refining
Water model experiments were performed for establishing highly efficient gas injection refining processes. Mechanical stirring was applied to disintegrate the injected bubbles and to disperse them widely in the bath. The bubble disintegration and dispersion were investigated by changing rotation mode (direction of rotation), rotation speed, blade size of the impeller and gas flow rate. Forward rotation of the impeller induced a stable tangential flow and could not disperse bubbles in the bath due to formation of a vortex around the impeller shaft. The tangential flow could be suppressed by forward–interrupt rotation, which could reduce the vortex formation to some degree. However, forward–interrupt rotation could not disperse the bubbles widely in the bath. Forward–reverse rotation could prevent the vortex formation completely and create a strong shear stress field, which intensified the bubble disintegration and dispersion in the bath. Higher impeller rotation speed and larger blade length in forward–reverse rotation could enhance the bubble disintegration and make the dispersed bubbles smaller. The bubble dispersion zone became wider with larger blade length. The bubble size tended to be larger at higher gas flow rates. However, its dependence on the gas flow rate became smaller at higher impeller rotation speed.
