Social Justice Youth Work: Actualizing Youth Rights, Monica Mcdaniel Jan 2017

Social Justice Youth Work: Actualizing Youth Rights, Monica Mcdaniel

Journal of Youth Development

This article explores models of prevention/intervention and positive youth development within the context of social justice. Both of these models seek to support young people, but they have vastly different methods and goals. The author argues that these models fall short of effectively supporting youth because they neglect to interrogate how power, privilege and oppressive forces shape a young person's identity and how that young person engages with society. Therefore, a new approach to working with youth is needed: a social justice youth work model. The author proposes this model as a means for youth and adults to work together …

Synthesis Of Ni-Fe Thin Films By Electrochemical Deposition Technique And Characterization Of Their Microstructures And Surface Morphologies, Umut Saraç, Mali̇k Kaya, Mevlana Celaletti̇n Baykul

Turkish Journal of Physics

Microstructural features and surface morphologies of Ni-Fe thin films fabricated by the electrochemical deposition technique have been experimentally studied. Ni-Fe thin films have been deposited under different deposition potentials and FeSO$_{4}$ concentrations. Energy dispersive X-ray measurements demonstrate that the Fe content decreases (increases) as the deposition potential (FeSO$_{4}$ concentration) is enhanced. All of the produced films exhibit an anomalous codeposition behavior. The effects of deposition potential and FeSO$_{4}$ concentrations on the degree of anomalous codeposition have been also characterized. X-ray diffraction studies reveal that the films have face-centered cubic crystallographic structures with [111] preferred crystallographic orientation regardless of the applied …

A Review Of The Recommendations Governing Quality Assurance Of Ultrasound Systems Used For Guidance In Prostate Brachytherapy, Andrea Jane Doyle, Deirdre King, Jacinta Browne

Articles

Ultrasound guided brachytherapy for the treatment of prostate cancer has become a routine treatment option, due to many benefits including patient recovery and dose localisation [1]; however it is not clear whether the standards which govern the image quality for these systems are adequate. Upon review of the recommended standards for ultrasound systems used in prostate brachytherapy procedures, the recommended tests do not appear to be specific to the clinical application of ultrasound guided prostate brachytherapy. Rather they are generic and similar to those recommended for other clinical applications such as general abdominal scanning [2]. Furthermore, there is growing evidence …
