Linking Local Knowledge and Satellite-Derived Land-Use/Land-Cover Change Information In Krabi Province, Thailand
No full textThis study was designed to gain an understanding of the linkage between development and sustainability of mangrove forest conversion in three coastal communities in Thailand. It presents a methodology that could potentially aid coastal communities in determining sustainable land use conversion approaches by considering the viewpoint of villagers. A remote sensing analysis of Landsat satellite images from 1989, 2001 and 2007 showed the results of a moderate, but sustained shrimp farming industry that only partially exploited mangrove forests. The three villages experienced a range of changes in mangrove forest area. The villagers\u27 perceptions (collected through field surveys) did not match the results from the remote sensing analysis and varied significantly. A logit multiple regression model was utilized to study the factors influencing whether villagers\u27 estimates agreed or disagreed with the remote sensing analysis. Results showed that the only variables statistically significant at the 0.10 level were age, occupation, and proximity to the mangrove resource. There is a widespread belief that one of the main negative effects of the development of shrimp farms is the pollution of water and, as a consequence, the reduction of wild catch. In this study, a majority of fishing households reported a reduction in wild catch, with nearly all attributing it to shrimp farms. A relatively small number of households noted positive effects from shrimp farming and listed these as an increase of income as a result of working at shrimp farms. The most common negative effects identified by the locals were water pollution, followed by a decrease in wild catch, and an increase in the number of mosquitoes. Although shrimp farm developers promised many benefits from this enterprise, very few were realized by the villagers. Integrating information from household surveys with data on land-cover change derived from remote sensing improves our understanding of the causes and processes of land cover change, and the perceptions of such changes. Integrating these two data sources illustrated that while shrimp farms did not have very many positive effects on the villagers, they were not as directly harmful to the mangrove forests as many believed

The Meaning of Lead Users Within the Context of Online Platforms in the Creative Industry
No full textPurpose
In today’s dynamic and rapidly evolving technologically advanced world, user innovation and open source sharing are becoming powerful phenomena, which can potentially change existing business models. In this paper we integrate multi-method research, focusing on a particular segment of innovating users defined as “lead users” by von Hippel (1986) to explore their meaning within the context of the previously non-researched creative industry, represented by 3D printing and design in one particular research setting. “Lead Users” are defined by academic research as having high incentives to innovate and being at the leading edge of an important market trend. Therefore, by distinguishing between different categories of lead users in the context of our chosen research setting, we aim to define their meaning in relation to the creative industry.
Methods
The study selected a particular research setting in order to obtain primary and secondary data. Primary data in the form of ten semi-structured qualitative interviews, based on a case study approach, was used to develop and further our knowledge on the meaning of lead users within the online creative community of Thingiverse; primary data was further obtained via quantitative techniques. Secondary data was obtained through observations from blogs, online documents, and articles from independent resources.
Findings
We find that they contribute to it by determining a unique model of innovation driven by intrinsic, extrinsic and mixed incentives, which, in turn, contribute to the types of resources the lead users add to the research setting. Analyzing evidence from our research findings, we gain insights, which we believe contribute to and enrich the existing academic literature, specifically
in relation to user entrepreneurship and sources of innovation, as well as evidence for the successful coexistence of mixed resources and mixed incentives. We find that the latter is enabled by a certain group of lead users, which have managed to successfully bridge the two polar worlds.
Value and Originality
To the knowledge of the author existing academic research has not explored the creative industry and its lead users so far, therefore, this paper will add novice aspects through its findings

Carbon stock losses and recovery observed for a mangrove ecosystem following a major hurricane in Southwest Florida
No full textStudies integrating mangrove in-situ observations and remote sensing analysis for specific sites often lack precise estimates of carbon stocks over time frames that include disturbance events. This study quantifies change in mangrove area from 1985 to 2018 with Landsat time series analysis, estimates above and belowground stored carbon using field data, and evaluates aboveground carbon stock changes after the 2004 Category 4, Hurricane Charley, in J.N. “Ding” Darling National Wildlife Refuge. Two allometric equation methods yielding similar results were used to estimate aboveground carbon content in three mangrove species found in the refuge. Aboveground carbon contained 67 (SE = 2) MgC ha−1 with a total refuge estimate of 74,504 MgC in 2018. Sediment contained 259 (SE = 28) MgC ha−1 for a total of 288,008 MgC in the refuge. The initial reduction in mangrove area caused by Hurricane Charley was between 0.6% and 5.3%, equivalent to between 427 MgC and 3,599 MgC under three different scenarios of carbon loss. As a result of the hurricane, approximately 61 ha of mangroves were disturbed, of which 24 ha had recovered by 2018, with 37 ha (~3% of the pre-hurricane mangrove area) still not recovered 14 years after the event. The 37 ha of mangroves that have not recovered are located in a tidally restricted area of the refuge. A longer recovery time in this area will likely result in a greater loss of carbon storage than in the rest of the refuge
