After Broadband: A Study of Organizational Use of Broadband in Southwest Alaska

The purpose of this research was to gain a preliminary understanding of how organizations including large and small businesses, Native corporations and organizations, and local and regional governments are using broadband that is now available in much of southwest Alaska. To learn about community access to broadband, interviews were also conducted with library and school staff in communities where broadband had been installed under the OWL (Online with Libraries) program. Further, the study identifies research from other sources that could help to predict what socio-economic impacts the availability and adoption of broadband may have in rural Alaska. Financial institutions use online connections for teller services and credit and debit card processing, and stated that more people in rural communities now have debit cards that they can use for online purchases and bill paying. Large retailers use online services for payroll, for pointof-sale (POS) transactions, and online ordering. Seafood processors rely heavily on connectivity with their head offices (generally in the lower 48) for administrative services including payroll, accounting, shipping and receiving, purchasing, and ERP (enterprise resource planning), and access data base software to track fish tickets. Seafood processors also provide Internet access for their employees, most of whom are seasonal and from other states or countries. Tourism businesses use broadband for online reservation systems and for guests, who increasingly demand connectivity even for remote vacations. Village corporations and tribal councils use online services to help their residents obtain hunting and fishing licenses and fishing permits, to learn about funding opportunities, and to file reports on grants. Local Governments connect online for interoffice communications and for payroll and other administrative functions. Other online applications and services include providing remote desktop access from other agency sites, use of online tools for land management and mapping, training including webinars for workforce development, and providing access to social services for clients. An economic development organization sends newsletters to communities electronically and packets of documents to its board members rather than relying on fax or courier. Websites are important for tourism-related businesses to advertise and promote their businesses and for nonprofits and local governments to provide information about their services. 5 Broadband now plays many roles in rural education. Most students are required to use the Internet for class assignments. High school students can connect to classes in advanced subjects in other communities, and may complete online courses for college credit. Libraries remain important locations for community access, with residents going online to connect with friends on Facebook, as well as to download content for e-books, file income tax, and apply for jobs and government benefits. School and library Wi-Fi provides access inside and near the buildings for residents with smartphones. Despite enthusiasm for broadband and the adoption of many broadband-based applications and services, most organizations interviewed identified problems with broadband, particularly with the pricing, stating that the terrestrial broadband network is too costly for them to take full advantage of online services and applications. While the scope of this study was too limited to estimate long-term benefits, it found that broadband is highly valued and increasingly important to businesses and nonprofit organizations and local governments in southwest Alaska. Broadband helps businesses to be more efficient in their operations and to extend their reach to new customers and suppliers. It also helps to improve the effectiveness of public sector services such as those provided by borough and city governments and extends access to education and training. Broadband is also likely to be an important component of strategies to develop ecotourism and other ecosystem services.Support for this research came from Connect Alaska with funding from the National Telecommunications and Information Administration (NTIA) for the work of the State of Alaska Broadband Task Force, with additional support from GCI.Executive Summary / Introduction / Research Methodology / Technologies and Technical Support / Broadband Applications / Education and Community Access / Health Care / Benefits of Broadband in Southwest Alaska / Problems and Limitations / Potential Long-Term Social and Economic Impacts / Conclusions and Recommendations / Referemce

Top Leases and the Rule Against Perpetuities

The competition for oil and gas leases has resulted in an increase in the use of top leases to secure oil and gas leasehold estates. Top leases which are found to violate the Rule against Perpetuities could result in the loss of millions of dollars to the lessee. The author examines top leasing in light of the Rule against Perpetuities and concludes that absent a savings clause, such leases violate the Rule. A savings clause is proposed which would save an otherwise invalid lease thereby circumventing the harsh application of the Rule

Translation Studies on an Annular Field Reversed Configuration Device for Space Propulsion

This research investigated annular field reversed configuration (AFRC)devices for high power electric propulsion by demonstrating the acceleration of these plasmoids using an experimental prototype and measuring the plasmoid\u27s velocity, impulse, and energy efficiency. The AFRC plasmoid translation experiment was design and constructed with the aid of a dynamic circuit model. Two versions of the experiment were built, using underdamped RLC circuits at 10 kHz and 20 kHz. Input energies were varied from 100 J/pulse to 1000 J/pulse for the 10 kHz bank and 100 J/pulse for the 20 kHz bank. The plasmoids were formed in static gas fill of argon, from 1 mTorr to 50 mTorr. The translation of the plasmoid was accomplished by incorporating a small taper into the outer coil, with a half angle of 2°. Magnetic field diagnostics, plasma probes, and single-frame imaging were used to measure the plasmoid\u27s velocity and to diagnose plasmoid behavior. Full details of the device design, construction, and diagnostics are provided in this dissertation. The results from the experiment demonstrated that a repeatable AFRC plasmoid was produced between the coils, yet failed to translate for all tested conditions. The data revealed the plasmoid was limited in lifetime to only a few (4-10) μs, too short for translation at low energy. A global stability study showed that the plasma suffered a radial collapse onto the inner wall early in its lifecycle. The radial collapse was traced to a magnetic pressure imbalance. A correction made to the circuit was successful in restoring an equilibrium pressure balance and prolonging radial stability by an additional 2.5 μs. The equilibrium state was sufficient to confirm that the plasmoid current in an AFRC reaches a steady-state prior to the peak of the coil currents. This implies that the plasmoid will always be driven to the inner wall, unless it translates from the coils prior to peak coil currents. However, ejection of the plasmoid before the peak coil currents results in severe efficiency losses. These results demonstrate the difficulty in designing an AFRC experiment for translation as balancing the different requirements for stability, balance, and efficient translation can have competing consequences

Genetic heterogeneity of residual variance in broiler chickens

Aims were to estimate the extent of genetic heterogeneity in environmental variance. Data comprised 99 535 records of 35-day body weights from broiler chickens reared in a controlled environment. Residual variance within dam families was estimated using ASREML, after fitting fixed effects such as genetic groups and hatches, for each of 377 genetically contemporary sires with a large number of progeny ($>$100 males or females each). Residual variance was computed separately for male and female offspring, and after correction for sampling, strong evidence for heterogeneity was found, the standard deviation between sires in within variance amounting to 15–18% of its mean. Reanalysis using log-transformed data gave similar results, and elimination of 2–3% of outlier data reduced the heterogeneity but it was still over 10%. The correlation between estimates for males and females was low, however. The correlation between sire effects on progeny mean and residual variance for body weight was small and negative (-0.1). Using a data set bigger than any yet presented and on a trait measurable in both sexes, this study has shown evidence for heterogeneity in the residual variance, which could not be explained by segregation of major genes unless very few determined the trait

In vivo neurophysiological recordings from geniculate ganglia: taste response properties of individual greater superficial petrosal and chorda tympani neurones

Coding of gustatory information is complex and unique among sensory systems; information is received by multiple receptor populations located throughout the oral cavity and carried to a single central relay by four separate nerves. The geniculate ganglion is the location of the somata of two of these nerves, the greater superficial petrosal (GSP) and the chorda tympani (CT). The GSP innervates taste buds on the palate and the CT innervates taste buds on the anterior tongue. To obtain requisite taste response profiles of GSP neurones, we recorded neurophysiological responses to taste stimuli of individual geniculate ganglion neurones in vivo in the rat and compared them to those from the CT. GSP neurones had a distinct pattern of responding compared to CT neurones. For example, a small subset of GSP neurones had high response frequencies to sucrose stimulation, whereas no CT neurones had high response frequencies to sucrose. In contrast, NaCl elicited high response frequencies in a small subset of CT neurones and elicited moderate response frequencies in a relatively large proportion of GSP neurones. The robust whole‐nerve response to sucrose in the GSP may be attributable to relatively few, narrowly tuned neurones, whereas the response to NaCl in the GSP may relate to proportionately more, widely tuned neurones. These results demonstrate the diversity in the initial stages of sensory coding for two separate gustatory nerves involved in the ingestion or rejection of taste solutions, and may have implications for central coding of gustatory quality and concentration as well as coding of information used in controlling energy, fluid and electrolyte homeostasis

Toward Universal Broadband in Rural Alaska

The TERRA-Southwest project is extending broadband service to 65 communities in the Bristol Bay, Bethel and Yukon-Kuskokwim regions. A stimulus project funded by a combination of grants and loans from the Rural Utilities Service (RUS), TERRA-Southwest has installed a middle-mile network using optical fiber and terrestrial microwave. Last-mile service will be through fixed wireless or interconnection with local telephone networks. The State of Alaska, through its designee Connect Alaska, also received federal stimulus funding from the National Telecommunications and Information Administration (NTIA) for tasks that include support for an Alaska Broadband Task Force “to both formalize a strategic broadband plan for the state of Alaska and coordinate broadband activities across relevant agencies and organizations.” Thus, a study of the impact of the TERRA project in southwest Alaska is both relevant and timely. This first phase provides baseline data on current access to and use of ICTs and Internet connectivity in rural Alaska, and some insights about perceived benefits and potential barriers to adoption of broadband. It is also intended to provide guidance to the State Broadband Task Force in determining how the extension of broadband throughout the state could contribute to education, social services, and economic activities that would enhance Alaska’s future. Results of the research could also be used proactively to develop strategies to encourage broadband adoption, and to identify applications and support needed by users with limited ICT skills.Connect Alaska.

Expanding Disease Definitions in Guidelines and Expert Panel Ties to Industry:A Cross-sectional Study of Common Conditions in the United States

BACKGROUND: Financial ties between health professionals and industry may unduly influence professional judgments and some researchers have suggested that widening disease definitions may be one driver of over-diagnosis, bringing potentially unnecessary labeling and harm. We aimed to identify guidelines in which disease definitions were changed, to assess whether any proposed changes would increase the numbers of individuals considered to have the disease, whether potential harms of expanding disease definitions were investigated, and the extent of members' industry ties. METHODS AND FINDINGS: We undertook a cross-sectional study of the most recent publication between 2000 and 2013 from national and international guideline panels making decisions about definitions or diagnostic criteria for common conditions in the United States. We assessed whether proposed changes widened or narrowed disease definitions, rationales offered, mention of potential harms of those changes, and the nature and extent of disclosed ties between members and pharmaceutical or device companies. Of 16 publications on 14 common conditions, ten proposed changes widening and one narrowing definitions. For five, impact was unclear. Widening fell into three categories: creating “pre-disease”; lowering diagnostic thresholds; and proposing earlier or different diagnostic methods. Rationales included standardising diagnostic criteria and new evidence about risks for people previously considered to not have the disease. No publication included rigorous assessment of potential harms of proposed changes. Among 14 panels with disclosures, the average proportion of members with industry ties was 75%. Twelve were chaired by people with ties. For members with ties, the median number of companies to which they had ties was seven. Companies with ties to the highest proportions of members were active in the relevant therapeutic area. Limitations arise from reliance on only disclosed ties, and exclusion of conditions too broad to enable analysis of single panel publications. CONCLUSIONS: For the common conditions studied, a majority of panels proposed changes to disease definitions that increased the number of individuals considered to have the disease, none reported rigorous assessment of potential harms of that widening, and most had a majority of members disclosing financial ties to pharmaceutical companies.
