| Active- and passive-acoustic methods are widely used tools for observing, monitoring, and understanding marine ecosystems. From 25 to 28 May 2015, 214 scientists from 31 nations gathered for an ICES symposium on Marine Ecosystem Acoustics (SoME Acoustics) to discuss three major themes related to acoustic observations of marine ecosystems: (i) recent developments in acoustic and platform technologies; (ii) acoustic characterisation of aquatic organisms, ecosystem structure, and ecosystem processes; and (iii) contribution of acoustics to integrated ecosystem assessments and management. The development of, and access to new instruments, such as broad bandwidth systems, enables insightful ecological studies and innovative management approaches. Unresolved... |

| Three-quarters of U.S. residents used the Internet to access information, education, and services in 2007. Broadband Internet access is becoming essential for both businesses and households; many compare its evolution to other technologies now considered common necessities—such as cars, electricity, televisions, microwave ovens, and cell phones. Although rural residents enjoy widespread access to the Internet, they are less likely to have high-speed, or broadband, Internet access than their urban counterparts. Circumstantial evidence suggests that the difference in access may lie in the higher cost and limited availability of broadband Internet in rural areas. As a result, rural residents depend more on Internet use outside of the home, in places like the... |

| This paper examines the shifting influence of household characteristics and telecommunications infrastructure on the residential broadband adoption decision for Oklahoma residents between 2003 and 2006. In particular, the spread of wired telecommunications infrastructure (namely cable Internet and Digital Subscriber Lines (DSL)) is examined, along with the effect that this diffusion has had on broadband access rates. The data indicates that the gap in broadband access rates between rural and urban areas has remained relatively constant over this period despite increased levels of cable and DSL throughout the state. In addition, an inter-temporal decomposition shows that the increasing levels of infrastructure are not the dominant cause of higher broadband... |

| Rural communities suffer from both supply and demand-side disadvantages when dealing with Internet access. Telecommunications companies are less likely to provide them with needed infrastructure due to lower population densities, and they also tend to have lower levels of specific factors known to influence the access decision such as education and income. This study looks at the broadband Internet setting in Oklahoma over a 3-year period, examining the diffusion of both infrastructure and access rates. A non-linear decomposition technique allows for measurement of how specific characteristics, including the availability of infrastructure, contribute to observed metropolitan – micropolitan or metropolitan – noncore “digital divides.” The results... |

| As broadband—or high-speed—Internet use has spread, Internet applications requiring high transmission speeds have become an integral part of the “Information Economy,” raising concerns about those who lack broadband access. This report analyzes (1) rural broadband use by consumers, the community-at-large, and businesses; (2) rural broadband availability; and (3) broadband’s social and economic effects on rural areas. It also summarizes results from an ERS-sponsored workshop on rural broadband use, and other ERS-commissioned studies. In general, rural communities have less broadband Internet use than metro communities, with differing degrees of broadband availability across rural communities. Rural communities that had greater broadband Internet access had... |
