Are We Providing Preferred Floral Resources for Bees in Our Neighborhoods?: Assessing the Relationship Between Small Scale Vegetation Metrics and Bee Presence in SE Portland

Wallace, Hailey 12 July 2019 (has links)
Bee pollinators can thrive in highly urbanized environments if their preferred floral resources and habitat types are available. Enhanced pollinator habitats are being created globally, with a large local effort in Portland, Oregon. This project determined if we were providing the most preferred floral resources at enhanced pollinator sites for bees, if floral resources were available throughout the season, and if differences in dietary preferences between native and honey bees would allow for the identification of "native bee floral resources" in South East Portland. Bee pollinators were monitored from June to August at three enhanced pollinator sites in South East Portland, Oregon. A total of 566 individual bees were observed, tiny dark bees and bumblebees composed the large majority of the urban bee composition. Vegetation metrics and bee presence were correlated using a Generalized Linear Mixed Model and significant variables that predicted bee presence included Solidago canadenisis (p-value 0.0024), density of floral resources (p-value

Information system success: evaluation of a carbon accounting and sequestration system

Smart, William J Unknown Date (has links)
The primary aim of the research conducted for this thesis was to develop a predictive model of information systems success for a publicly-available, web-based application that provides information to users on both the value of carbon credits that result from sequestration of carbon in a forest as well as potential earnings from supply of saleable timber. The application, also developed as part of this research, is called the CO2 Calculator. In addition attitudes of respondents to climate change and carbon sequestration were also gauged to ascertain their knowledge of key environmental issues relevant to the system.The model used as the foundation for the research is the DeLone and McLean (1992, 2002, 2003) model of information systems success. This model was adapted to measure information systems success for the CO2 Calculator which is a publicly available, web-based application rather than a proprietary, task-specific, organizationally focused application as measured in the prior research.Data was collected via a survey dispatched by email to users who accessed the CO2 Calculator. The survey instrument used builds on the existing work of Torkzadeh and Doll (1988, 1999), Seddon and Kiew (1994) and Torkzadeh et al. (2005). All of these researchers used variations of the End User Survey (EUS) to collect data on end users’ perceptions of the success of various applications, all of which were internal, organisationally-focussed, task specific, proprietary systems. This meant the survey items used for the current research were adapted to measure users’ attitudes to a publicly-available, web-based application that had no task-specific roles in an organisation.Analysis of the data proceeded in two distinct phases. The first phase was the examination and presentation of descriptive information about the demographic characteristics of the sample and the users’ attitudes to climate change, carbon sequestration and the overall success of the CO2 Calculator. The descriptive data indicated the respondents are a technologically literate group who have concerns related to environmental management and the use of land for sustainable practices. It also showed that the users were extremely satisfied with the CO2 Calculator.In the second phase Exploratory Factor Analysis (EFA) was used to examine the constructs underlying the data and Structural Equation Modelling (SEM) was used to examine the relationships among the constructs. Both the EFA and SEM resulted in structures and relationships that differed from the hypothesised outcomes and revealed a set of constructs and relationships that were clearly associated with the success of a publicly-available, web based application with different theoretical associations than those found by previous researchers examining organisationally-focussed, proprietary applications.Regression analyses were also conducted to check the relationships among constructs that were omitted from the final structural model, but were on the hypothesised model. Support for their inclusion in further studies was found as the analysis identified that the scales used to measure these constructs were significant predictors of the outcome variables although not when networked with those constructs that were on the final measurement model.Notwithstanding the limitations of the research, it has resulted in the identification of a predictive model of information success for web-based, publicly available, nonorganisationally focused systems.

The theoretical and practical dimensions of pounamu management

Hope-Pearson, E.W., n/a January 2002 (has links)
The vesting of pounamu back to Te Runanga o Ngai Tahu brings to the fore a whole new dimension of resource mangement to New Zealand�s wider resource management environment. As is highlighted in this study and noted by a number of academics, Maori people, like other indigenous communities, have their own planning systems values and appropriate processes for decision-making about the environment. But the relevance of such indigenous management systems has long been overlooked by the decision makers and authorities to the continued frustration and anxiety of indigenous peoples. This lack of recognition has been at the fore as a concept fundamental to many indigenous peoples grievances, both past and present. The subsequent vesting of pounamu has brought about the validation that Maori have to resource management rights. In identifying issues associated with the management of natural resources by indigenous peoples, this study provides an examination of number theoretical concepts and a practical dimension associated with the management of natural resources by indigenous peoples and has placed pounamu in context. The placement of pounamu in context has provided the basis from which a number of central issues were identified and discussed. A combination a literature study, analysis of an application traditional knowledge in a contemporary context and in-depth interviews and liaison with key stakeholders involved directly and indirectly in the management of pounmau were undertaken, has established that the management of natural resources by indigenous people is more about the management of number of associated processes rather than about the management of a single commodity, in this instance pounamu. Within these processes there exist a number of complex relationships that reflect the fundamental transaction of power and privilege associated with natural resource management. Further conclusions that this study has made, is the increasing need and importance of legislatures and planning professionals alike to further recognise the validity and become familiar with alternate methods of resource management and the application of indigenous systems and methods.
