Abstract Background Reintroducing predators is a promising conservation tool to help remedy human-caused ecosystem changes. However, the growth and spread of a reintroduced population is a spatiotemporal process that is driven by a suite of factors, such as habitat change, human activity, and prey availability. Sea otters (Enhydra lutris) are apex predators of nearshore marine ecosystems that had declined nearly to extinction across much of their range by the early 20th century. In Southeast Alaska, which is comprised of a diverse matrix of nearshore habitat and managed areas, reintroduction of 413 individuals in the late 1960s initiated the growth and spread of a population that now exceeds 25,000. Methods Periodic aerial surveys in the region provide a time series of spatially-explicit data to investigate factors influencing this successful and ongoing recovery. We integrated an ecological diffusion model that accounted for spatially-variable motility and density-dependent population growth, as well as multiple population epicenters, into a Bayesian hierarchical framework to help understand the factors influencing the success of this recovery. Results Our results indicated that sea otters exhibited higher residence time as well as greater equilibrium abundance in Glacier Bay, a protected area, and in areas where there is limited or no commercial fishing. Asymptotic spread rates suggested sea otters colonized Southeast Alaska at rates of 1–8 km/yr with lower rates occurring in areas correlated with higher residence time, which primarily included areas near shore and closed to commercial fishing. Further, we found that the intrinsic growth rate of sea otters may be higher than previous estimates suggested. Conclusions This study shows how predator recolonization can occur from multiple population epicenters. Additionally, our results suggest spatial heterogeneity in the physical environment as well as human activity and management can influence recolonization processes, both in terms of movement (or motility) and density dependence.

Despite the current development of Internet marketing, understanding the effective use of the Internet still poses problems for academic researchers and marketers (Kassaye, 1999). This research attempts to empirically explore some aspects of the factors influencing commercial company Internet and Web development. The key factors considered for company Internet and Web site development are technology capacity, the use of different developers, company on-line measurement patterns and marketing executives’ Web site knowledge. As a result of a cross-sectional comparative study of ‘effective’ and ‘ineffective’ companies, the findings indicate that companies with better performance from Web sites tend to possess higher technological capabilities for Internet-based marketing. It seems that their marketing executives have more knowledge of technical aspects of Web site development. They tend to be early Internet adopters using a multiple approach to measure their on-line performance. These results help to improve general understanding of company effectiveness in developing on-line marketing strategies.

Third Person

This study investigated the effect of first-person and third-person perceptions of web site information. Responses from a telephone survey of 226 participants in a stratified random sample indicated that (1) most participants had higher evaluations for television news than for news received on the Internet; (2) a third-person effect was present in that most respondents generally thought that other people found the Internet easier to use than they did, and that other people were more likely to believe Internet information and trust the sources of Internet information than they would. Also, (3), evaluations of information on a particular web site could be increased by providing links to other web sites on the same topic. Perhaps links to other web sites may serve as either a “referencing” function or a social confirmation function to increase evaluations of web site information.

Three-dimensional electrode treating coking waste water was studied in the experiment, which is widely used in treating organic waste water. The high carbon-bearing metallized pellets was used as the third electrode of three-dimensional electrode reactor. Factors of three-dimensional electrode including residence time, voltage and air flux were studied. It was shown that all of the above mentioned factors have effect on coking wastewater. And also the optimal parameters were obtained in the experiment.
