Developing design capability in nonprofit organizations

© 2017 Massachusetts Institute of Technology. This article presents findings from a two-year longitudinal action, research study exploring the challenges and outcomes of attempting to develop design capability in one of Australia’s largest non-profit aged-care providers. The research identifies four distinct objectives for design utilization in practice, and suggests that existing approaches for design utilization overlook non-profit organizations that seek both economic and social viability. While the objectives of realizing economic and social outcomes are addressed in design literature, there is an absence of literature detailing how non-profit organizations could utilize design to realize these outcomes. This research, therefore, contributes the non-profit design ladder-a framework to assist non-profit organizations to further develop their utilization of design and foster design as an organizational capability

A modified cementing technique using BoneSource to augment fixation of the acetabulum in a sheep model

Background and purpose Our aim was to prove in an animal model that the use of HA paste at the cement-bone interface in the acetabulum would improve fixation. We examined, in sheep, the effect of interposing a layer of hydroxyapatite cement around the periphery of a polyethylene socket prior to fixing it using polymethylemethacrylate (PMMA). Methods We made a randomized study involving 22 sheep to test whether the application of BoneSource hydroxyapatite material to the surface of the ovine acetabulum prior to cementing a polyethylene cup at hip arthroplasty improved the fixation and the nature of the interface. We studied the gross radiographical appearance of the implant-bone interface and the histological appearance at the interface. Results There were more radiolucencies evident in the control group. Histologically, only sheep randomized into the BoneSource group exhibited a fully osseointegrated interface. Use of the hydroxyapatite material did not confer any detrimental effects. In some cases the material appeared to have been fully resorbed. When the material was evident on histological section, it was incorporated into an osseointegrated interface. There was no giant cell reaction present in any case. There was no evidence of migration of BoneSource to the articulation. Interpretation The application of HA material prior to cementation of a socket produced an improved interface. The technique may be useful in man with to extend the longevity of the cemented implant by protecting the socket interface from the effect of hydrodynamic fluid flow and particulate debris
