Rural Broadband Internet Access Supply and Demand
Internet use has grown rapidly over the last 15 years and so has its integration into the rural economy. Connecting to the Internet via high-speed technology such as DSL lines, cable, satellite, and wireless networks increases bandwidth and makes the Internet much more useful to businesses, households, and governments. Rural households are almost as likely as urban households to use the Internet. Broadband Internet access in rural areas has been less prevalent than in much more densely populated areas of the country. Evidence suggests that the difference may lie in the higher cost or less availability of broadband Internet access in rural areas. The paucity of national geographically-specific data, however, presents a challenge in trying to analyze questions of broadband take-up. Data from the June Agricultural Surveys, however, address this. The other difficulty has been obtaining local price in demand analysis. We use ARMS and industry data to develop local broadband service price indices. We use descriptive statistics and binomial logit models in our analysis. The data shows sharp differences in conversion rates across the country, and when also considering the changes over time giving some credence to the common hypothesis that people do choose to use broadband if given the option. Farms were unlikely to make the direct jump from no Internet use to Internet use with broadband access; farms that already had Internet access were more likely to convert to broadband Internet access. Some of the farms that did not convert already had broadband Internet access by 2005, roughly 24 percent of all farms using the Internet in 2005. The preponderance of DSL service for farms indicates both the mostly rural location of most farms as well as Internet users finding satellite a less desirable option. While broadband Internet access availability is necessary for take-up of broadband Internet access, there are other factors that are also limiting broadband Internet use such as price of access, age of user, household income, and educational attainment.broadband Internet access, rural communities, farm communities, Community/Rural/Urban Development, Research and Development/Tech Change/Emerging Technologies, Research Methods/ Statistical Methods, O33, R0,
Archaeological research in the Canary Islands: island archaeology off Africaβs Atlantic coast
Island archaeology is a well-established field within the wider discipline, but African contributions to it remain scarce. The Canary Islands are unusual in the broader African context for their relatively long history of occupation (~2000 years) and the intensity with which archaeological research has been, and is, undertaken there. Much of that research, however, has focused on specifically Canarian issues, including efforts to demonstrate connections between the islandsβ initial settlement and the Classical Mediterranean world. Relatively little of it has been conducted within the broader comparative framework that an island archaeology perspective provides. Additionally, much of the Canarian literature is not directly accessible to non-Hispanophones. In response, I synthesize what is currently known about the archaeology of the Canary Islands, focusing on determining when, how, and by whom they were first settled; the impacts of human settlement on their environments; inter-island variability in precolonial subsistence, social, and political trajectories; and the record left by European contact and subsequent colonization, which began in the 14th century AD. As well as pointing to further opportunities for research within the archipelago, I simultaneously map out several areas where archaeological work there could contribute to wider debates in island archaeology as a whole
Implementation of the Bologna Process and language education in Russia
AbstractThe article examines the nature of the Bologna Process reforms and their impact on language education in Russian higher education institutions. An analysis is made of the reforms in terms of structural impact, comparing the likely advantages and disadvantages of such a system for Russia. Attitudes of various social actors to the Bologna reforms are examined. Issues of academic mobility and its consequences are discussed. Questions of diploma recognition and the introduction of ECTS are addressed. Conclusions are made on how best the Bologna Reforms might be implemented in order to enhance, rather than harm, language education in Russian HEIs
The impact of a post-take ward round pharmacist on the risk score and enactment of medication-related recommendations
There is a scarcity of published research describing the impact of a pharmacist on the post-take ward round (PTWR) in addition to ward-based pharmacy services. The aim of this paper was to evaluate the impact of clinical pharmacists' participation on the PTWR on the risk assessment scores of medication-related recommendations with and without a pharmacist. This includes medication-related recommendations occurring on the PTWR and those recommendations made by the ward-based pharmacist on the inpatient ward. A pre-post intervention study was undertaken that compared the impact of adding a pharmacist to the PTWR compared with ward-based pharmacist services alone. A panel reviewed the risk of not acting on medication recommendations that was made on the PTWR and those recorded by the ward-based pharmacist. The relationship between the risk scores and the number and proportion of recommendations that led to action were compared between study groups. There were more medication-related recommendations on the PTWR in the intervention group when a pharmacist was present. Proportionately fewer were in the 'very high and extreme' risk category. Although there was no difference in the number of ward pharmacist recommendations between groups, there was a significantly higher proportion of ward pharmacist recommendations in the "very high and extreme" category in those patients who had been seen on a PTWR attended by a pharmacist than when a pharmacist was not present. There were a greater proportion of "low and medium" risk actionable medication recommendations actioned on the PTWR in the intervention group; and no difference in the risk scores in ward pharmacist recommendations actioned between groups. Overall, the proportion of recommendations that were actioned was higher for those made on the PTWR compared with the ward. The addition of a pharmacist to the PTWR resulted in an increase in low, medium, and high risk recommendations on the PTWR, more very high and extreme risk recommendations made by the ward-based pharmacist, plus an increased number of recommendations being actioned during the patients' admission
Nickel Mixing in the Outer Layers of SN 1987A
Supernova 1987A remains the most well-observed and well-studied supernova to
date. Observations produced excellent broad-band photometric and spectroscopic
coverage over a wide wavelength range at all epochs. Here, we focus on the very
early spectroscopic observations. Only recently have numerical models been of
sufficient detail to accurately explain the observed spectra. In SN 1987A, good
agreement has been found between observed and synthetic spectra for day one,
but by day four, the predicted Balmer lines become much weaker than the
observed lines. We present the results of work based on a
radiation-hydrodynamic model by Blinnikov and collaborators. Synthetic non-LTE
spectra generated from this model by the general radiation transfer code
PHOENIX strongly support the theory that significant mixing of nickel into the
outer envelope is required to maintain strong Balmer lines. Preliminary results
suggest a lower limit to the average nickel mass of 1.0 \times 10^{-5} solar
masses is required above 5000 \kmps by day four. PHOENIX models thus have the
potential to be a sensitive probe for nickel mixing in the outer layers of a
supernova.Comment: 16 pages, 7 figures, ApJ, v556 2001 (in press
Early CRT monitoring using time-domain optical coherence tomography does not add to visual acuity for predicting visual loss in patients with central retinal vein occlusion treated with intravitreal ranibizumab:A secondary analysis of trial data
Our primary purpose was to assess the clinical (predictive) validity of central retinal thickness (CRT) and best corrected visual acuity (BCVA) at 1 week and 1 month after starting treatment with ranibizumab for central retinal vein occlusion. The authors also assessed detectability of response to treatment
