Repurposing literacy: the uses of Richard Hoggart for creative education

After 50 years, what are the implications of Uses of Literacy for educational modernisation, in the light of subsequent changes from 'read only' literacy to 'read-write' uses of multimedia? This chapter argues that a broad extension of popular literacy via consumer-created digital content offers not only emancipationist potential in line with Hoggart's own project, but also economic benefits via the dynamics of creative innovation. Multimedia 'popular entertainments' pose a challenge to formal education, but not in the way that Hoggart feared. Instead of producing 'tamed helots,' commercial culture may be outpacing formal schooling in promoting creative digital literacy via entrepreneurial and distributed learning. It may indeed be that those in need of a creative make-over are not teenagers but teachers

Best Practices in Endangered Species Recovery Planning: Lessons for the Conservation of Maine’s Atlantic Salmon

The call for federal listing of Atlantic salmon as endangered implies that such action will result in a recovery plan for the species that is superior to Maine ’s Atlantic Salmon Conservation Plan. In this article the authors compare the Maine plan against the findings of a recent review of Endangered Species Act recovery plans. The review, conducted by the Society for Conservation Biology in collaboration with the U.S. Fish and Wildlife Service, assessed the quality of a national sample of Endangered Species Act recovery plans with the intention of identifying “best practice.” By comparing the Maine plan to the findings of this review, the authors indicate areas where Maine’s plan is strong and suggest areas where there may be room for improvement

Strategies for the discontinuation of humidified high flow nasal cannula (HHFNC) in preterm infants (Review)

BACKGROUND: Humidified high flow nasal cannula (HHFNC) delivers humidified gas at increased flow rates via binasal prongs and is becoming widely accepted as a method of non-invasive respiratory support for preterm infants. While indications for the use of (HHFNC) and its associated risks and benefits are being investigated, the best strategy for the discontinuation of HHFNC remains unknown. At what point an infant is considered stable enough to attempt to start withdrawing their HHFNC is not known. The criteria for a failed attempt at HHFNC discontinuation is also unclear

Re-municipalization of public services: trend or hype?

Re-municipalization is part of a broader set of reverse privatization reforms. We argue the term re-municipalization lacks conceptual clarity, confusing municipal level reversals from national ones, new service delivery from reversals, and mixed market positions from full public control. This conceptual confusion makes measurement of re-municipalization difficult. While more case studies are being discovered, quantitative time series studies do not show re-municipalization is increasing. Much case study based research argues re-municipalization is politically transformative, but quantitative research generally finds re-municipalization to be part of a pragmatic market management process, a position confirmed by the papers in this special issue

Toxicity of Lunar and Martian Dust Simulants to Alveolar Macrophages Isolated from Human Volunteers

NASA is planning to build a habitat on the Moon and use the Moon as a stepping stone to Mars. JSC-1, an Arizona volcanic ash that has mineral properties similar to lunar soil, is used to produce lunar environments for instrument and equipment testing. NASA is concerned about potential health risks to workers exposed to these fine dusts in test facilities. The potential toxicity of JSC-1 and a Martian soil simulant (JSC-Mars-1, a Hawaiian volcanic ash) was evaluated using human alveolar macrophages (HAM) isolated from volunteers; titanium dioxide and quartz were used as reference dusts. This investigation is a prerequisite to studies of actual lunar dust. HAM were treated in vitro with these test dusts for 24 h; assays of cell viability and apoptosis showed that JSC-1 and TiO2 were comparable, and more toxic than saline control, but less toxic than quartz. HAM treated with JSC-1 or JSC-Mars 1 showed a dose-dependent increase in cytotoxicity. To elucidate the mechanism by which these dusts induce apoptosis, we investigated the involvement of the scavenger receptor (SR). Pretreatment of cells with polyinosinic acid, an SR blocker, significantly inhibited both apoptosis and necrosis. These results suggest HAM cytotoxicity may be initiated by interaction of the dust particles with SR. Besides being cytotoxic, silica is known to induce shifting of HAM phenotypes to an immune active status. The immunomodulatory effect of the simulants was investigated. Treatment of HAM with either simulant caused preferential damage to the suppressor macrophage subpopulation, leading to a net increase in the ratio of activator (RFD1+) to suppressor (RFD1+7+) macrophages, a result similar to treatment with silica. It is recommended that appropriate precautions be used to minimize exposure to these fine dusts in large-scale engineering applications

Success and Failure for Children Born with Facial Clefts in Africa: A 15-Year Follow-up

Background: This study reviews the 15year program of our Department of Pediatric Surgery for the treatment and follow-up of children born with a cleft in Benin and Togo. Methods: We analyzed files of children born in Africa with a cleft. They were referred to us through a nongovernmental organization (NGO) between 1993 and 2008 and assessed in Africa by local pediatricians before and after surgery. Operations were performed by our team. Results: Two hundred files were reviewed: 60 cases of unilateral cleft lip, seven of bilateral cleft lip, 44 of unilateral cleft lip palate (UCLP), 29 of bilateral cleft lip palate (BCLP), 53 of cleft palate (CP), three of bilateral oro-ocular cleft, one of unilateral and two of median clefts (Binder), and one of commissural cleft. Sixty-nine (35%) of these cases were not operated in Africa: 25 (12.5%) had not shown up, 28 (15%) were considered unfit for surgery (Down's syndrome, HIV-positive, malnutrition, cardiac malformation), and 16 (7.5%) were transferred to Switzerland. Palatal fistula occurred in 20% of UCLP, 30% of BCLP, and 16% of CP. Evaluation of speech after palate surgery gave less than 50% of socially acceptable speech. Conclusions: Our partnership with a NGO and a local team makes it possible to treat and subsequently follow children born with a cleft in West Africa. Surgery is performed under good conditions. If aesthetic results are a success, functional results after palate surgery need further improvement to promote integration in school and social lif

Computer model to simulate testing at the National Transonic Facility

A computer model has been developed to simulate the processes involved in the operation of the National Transonic Facility (NTF), a large cryogenic wind tunnel at the Langley Research Center. The simulation was verified by comparing the simulated results with previously acquired data from three experimental wind tunnel test programs in the NTF. The comparisons suggest that the computer model simulates reasonably well the processes that determine the liquid nitrogen (LN2) consumption, electrical consumption, fan-on time, and the test time required to complete a test plan at the NTF. From these limited comparisons, it appears that the results from the simulation model are generally within about 10 percent of the actual NTF test results. The use of actual data acquisition times in the simulation produced better estimates of the LN2 usage, as expected. Additional comparisons are needed to refine the model constants. The model will typically produce optimistic results since the times and rates included in the model are typically the optimum values. Any deviation from the optimum values will lead to longer times or increased LN2 and electrical consumption for the proposed test plan. Computer code operating instructions and listings of sample input and output files have been included
