title: What have scholars retrieved from Walsh and Ungson (1991)? A citation context study

authors: Anderson, Marc Howard

subjects: citation analysis

abstract: Organizational memory is fundamentally important to organizational learning. The seminal work on organizational memory is Walsh and Ungson’s article published in the Academy of Management Review in 1991. More than 300 articles have cited this classic work, but a simple citation count reveals nothing about the nature of what has been retrieved. We examine this issue through a citation context analysis (i.e. content analysis) of the citations that citing authors have made to this classic article. Our analysis provides a richer understanding of which knowledge claims made by Walsh and Ungson have been retrieved and have had the greatest impact on later work in the area of organizational memory, and also what criticisms have been leveled against their claims. Through this analysis and a review of the citing articles that contain the largest number of citations to Walsh and Ungson, we identify several important directions for future research.

title: Surface projection for mixed pixel restoration

authors: Larkins, Robert L.

subjects: range imaging

abstract: Amplitude modulated full-field range-imagers are measurement devices that determine the range to an object simultaneously for each pixel in the scene, but due to the nature of this operation, they commonly suffer from the significant problem of mixed pixels. Once mixed pixels are identified a common procedure is to remove them from the scene; this solution is not ideal as the captured point cloud may become damaged. This paper introduces an alternative approach, in which mixed pixels are projected onto the surface that they should belong. This is achieved by breaking the area around an identified mixed pixel into two classes. A parametric surface is then fitted to the class closest to the mixed pixel, with this mixed pixel then being project onto this surface. The restoration procedure was tested using twelve simulated scenes designed to determine its accuracy and robustness. For these simulated scenes, 93% of the mixed pixels were restored to the surface to which they belong. This mixed pixel restoration process is shown to be accurate and robust for both simulated and real world scenes, thus provides a reliable alternative to removing mixed pixels that can be easily adapted to any mixed pixel detection algorithm.

title: Inside the Resource Management Act:  A Tainui Case Study

authors: Greensill, Angeline Ngahina

subjects: Maori

abstract: Under the Resource Management Act (RMA) 1991 councils are required to promote the sustainable management of physical and natural resources within their respective areas.    In carrying out their duties, councils are obliged to recognise and provide for the relationship of Māori with their culture, traditions, lands, waters and other taonga.  They are also required to have regard to kaitiakitanga, and to take into account the principles of te Tiriti o Waitangi when making decisions.    
This thesis focuses on the RMA experiences of Tainui, a hapū in Whaingaroa. It sets out to prove that in the last 19 years, since the enactment of the RMA, Waikato councils have failed to honour these obligations to Tainui.  While the RMA specifically provides for Māori interests, in reality those interests are contested and eroded by decision makers who write and enforce rules which inequitably affect Māori relationships with land and other taonga. 
The thesis engages multiple theories and methodologies including Kaupapa Māori, critical theory, autobiography, and a longitudinal case study to expose personal experiences that   bring the realities of planning impacts on Tainui to life.    The fact that Tainui has successfully appealed several council decisions to the Environment Court indicates that councils are failing to meet their obligations as laid out in the legislation.
