Imminent Geologic and Hydrologic Hazards on Fort Ord BLM Land

The Bureau of Land Management acquired 7,500 acres of land as part of the re-use of the decommissioned Fort Ord Army base. A variety of geologic hazards exist on the landscape including gully erosion, mass wasting, and decaying earthen dams. This short report highlights a few critical areas that deserve closer evaluation and remediation. Of particular concern are decaying earthen dams and mass wasting of tall stream banks that may impact BLM infrastructure or adjacent urban development. (Document contains 13 paGES)

A Surfboard for Riding the Wave

The report, A Surfboard for Riding the Wave, by the high level Knowledge Exchange expert group on research data called for a collaborative data infrastructure that will enable researchers and other stakeholders from education, society and business to use, re-use and exploit research data to the maximum benefit of science and society. The Knowledge Exchange partners have embraced this vision and commissioned a report that translates Riding the Wave into actions for the four partner countries and beyond. This paper builds on this report and presents an overview of the present situation with regard to research data in Denmark, Germany, the Netherlands and the United Kingdom and offers broad outlines for a possible action programme for the four countries in realising the envisaged collaborative data infrastructure. An action programme at the level of four countries will require the involvement of all stakeholders from the scientific community

The Value of Research Data

Scientific research revolves around the production, analysis, storage, management, and re-use of data. Data sharing offers important benefits for scientific progress and advancement of knowledge. However, several limitations and barriers in the general adoption of data sharing are still in place. Probably the most important challenge is that data sharing is not yet very common among scholars and is not yet seen as a regular activity among scientists, although important efforts are being invested in promoting data sharing. In addition, there is a relatively low commitment of scholars to cite data. The most important problems and challenges regarding data metrics are closely tied to the more general problems related to data sharing. The development of data metrics is dependent on the growth of data sharing practices, after all it is nothing more than the registration of researchers’ behaviour. At the same time, the availability of proper metrics can help researchers to make their data work more visible. This may subsequently act as an incentive for more data sharing and in this way a virtuous circle may be set in motion. This report seeks to further explore the possibilities of metrics for datasets (i.e. the creation of reliable data metrics) and an effective reward system that aligns the main interests of the main stakeholders involved in the process. The report reviews the current literature on data sharing and data metrics. It presents interviews with the main stakeholders on data sharing and data metrics. It also analyses the existing repositories and tools in the field of data sharing that have special relevance for the promotion and development of data metrics. On the basis of these three pillars, the report presents a number of solutions and necessary developments, as well as a set of recommendations regarding data metrics. The most important recommendations include the general adoption of data sharing and data publication among scholars; the development of a reward system for scientists that includes data metrics; reducing the costs of data publication; reducing existing negative cultural perceptions of researchers regarding data publication; developing standards for preservation, publication, identification and citation of datasets; more coordination of data repository initiatives; and further development of interoperability protocols across different actors.

IPR POLICY AND SCIENTIFIC RESEARCH KNOWLEDGE EXCHANGE REPORT FOR SCIENTIFIC POLICY MAKERS

The report provides recommendations to policy makers in science and scholarly research regarding IPR policy to increase the impact of research and make the outcomes more available. The report argues that the impact of publicly-funded research outputs can be increased through a fairer balance between private and public interest in copyright legislation. This will allow for wider access to and easier re-use of published research reports. The common practice of authors being required to assign all rights to a publisher restricts the impact of research outputs and should be replaced by wider use of a non-exclusive licence. Full access and re-use rights to research data should be encouraged through use of a research-friendly licence.

Knowledge Exchange Discussion paper on Open Knowledge

The development of an openly available layer of scholarly and scientific content requires access to all types of output from the scholarly and scientific process. Interoperable and sustainable infrastructure components are invaluable elements and the content should be clearly licensed for re-use. Open Knowledge will improve the discoverability and re-usability of content across the sectors, to the benefit of higher education and research and will help the (European) knowledge economy to move forward. In Autumn 2013, scoping sessions took place with experts to discuss their views around the value of making knowledge open and the steps which need to be taken to achieve this. These discussions are collected in the Knowledge Exchange discussion paper on Open Knowledge.

Novel Papillomaviruses in Free-Ranging Iberian Bats: No Virus-Host Co-evolution, No Strict Host Specificity, and Hints for Recombination

Papillomaviruses (PVs) are widespread pathogens. However, the extent of PV infections in bats remains largely unknown. This work represents the first comprehensive study of PVs in Iberian bats. We identified four novel PVs in the mucosa of free-ranging Eptesicus serotinus (EserPV1, EserPV2, and EserPV3) and Rhinolophus ferrumequinum (RferPV1) individuals and analyzed their phylogenetic relationships within the viral family. We further assessed their prevalence in different populations of E. serotinus and its close relative E. isabellinus. Although it is frequent to read that PVs co-evolve with their host, that PVs are highly species-specific, and that PVs do not usually recombine, our results suggest otherwise. First, strict virus-host co-evolution is rejected by the existence of five, distantly related bat PV lineages and by the lack of congruence between bats and bat PVs phylogenies. Second, the ability of EserPV2 and EserPV3 to infect two different bat species (E. serotinus and E. isabellinus) argues against strict host specificity. Finally, the description of a second noncoding region in the RferPV1 genome reinforces the view of an increased susceptibility to recombination in the E2-L2 genomic region. These findings prompt the question of whether the prevailing paradigms regarding PVs evolution should be reconsidered.

Pesquisa-design formação: uma proposta metodológica para a produção de Recursos Educacionais Abertos na cibercultura

Essa pesquisa inspirou-se nos movimentos sociais recentes relacionados à abertura de materiais digitais para compartilhamento, (re) uso e remixagem no ciberespaço. Assim, partimos da seguinte problemática: como desenvolver atos de currículo capazes de contribuir para a produção de Recursos Educacionais Abertos (REA) para a docência e aprendizagem na cibercultura? O objetivo foi desenvolver um dispositivo-metodológico como ato de currículo que atualiza a pesquisa-formação para o design de situações de aprendizagemensino e de artefatos pedagógicos que contemplem a autoria dos praticantes culturais. Para atingir o proposto, foi desenvolvido um dispositivo que atualiza o método da pesquisa-formação para a docência e aprendizagem na cibercultura (SANTOS, 2005; 2014) com alguns princípios da pesquisa-design (GRAVEMEIJER; COBB, 2006; van den AKKER, 1999; BROWN, 1992; COLLINS, 1992; NEWMAN, 1990; KELLY, 2003; RAMOS; STRUCHINER, 2008) para propiciar a produção de artefatos digitais utilizando os recursos oferecidos pelas plataformas da Web 2.0. A pesquisa-design formação, como método e o design interativo aberto como dispositivo, foram criados com o objetivo de sistematizar o processo de construção e implementação de atos de currículos e arquitetar percursos abertos em plataformas da Web 2.0. A metodologia proposta parte da bricolagem da pesquisa-formação multirreferencial na cibercultura com a pesquisa-design. A pesquisa está estruturada em quatro conceitos-tema importantes: a) educar na cibercultura: mídias em destaque; b) Design na Web 2.0: faça você mesmo e de preferência acompanhado; c) Professor-autor e a sua construção epistemológica e metodológica, e; d) Professor-autor em formação: enunciação, negociação e autoria. Essa pesquisa revelou alguns achados nas dimensões referente ao design como produto e processo, método e atos de currículo, que têm a intenção de contribuir para: a) a sistematização de processos de aprendizagemensino, promovendo a produção de artefatos digitais abertos por professores e alunos; b) o design estrutural e proposicional das atividades pedagógicas; c) a formação de sujeitos-autores na cibercultura. Portanto, esta pesquisa contribuiu para a autorização e autonomização dos praticantes culturais através da metodologia pesquisa-design formação bem como a disponibilização de materiais digitais abertos na cibercultura.

Comparison of stabilised/solidified mixes of model drill cuttings based on the North Sea and Red Sea Areas

Following the global stringent legislations regulating the wastes generated from the drilling process of oil exploration and production activities, the management of hazardous drill cuttings has become one of the pressing needs confronting the petroleum industry. Most of the prevalent treatment techniques adopted by oil companies are extremely expensive and/or the treated product has to be landfilled without any potential end-use; thereby rendering these solutions unsustainable. The technique of stabilisation/solidification is being investigated in this research to treat drill cuttings prior to landfilling or for potential re-use in construction products. Two case studies were explored namely North Sea and Red Sea. Given the known difficulties with stabilising/solidifying oils and chlorides, this research made use of model drill cutting mixes based on typical drill cutting from the two case studies, which contained 4.2% and 10.95% average concentrations of hydrocarbons; and 2.03% and 2.13% of chlorides, by weight respectively. A number of different binders, including a range of conventional viz. Portland cement (PC) as well as less-conventional viz. zeolite, or waste binders viz. cement kiln dust (CKD), fly ash and compost were tested to assess their ability to treat the North Sea and Red Sea model drill cuttings. The dry binder content by weight was 10%, 20% and 30%. In addition, raw drill cuttings from one of the North Sea offshore rigs were stabilised/solidified using 30% PC. The characteristics of the final stabilised/solidified product were finally compared to those of thermally treated cuttings. The effectiveness of the treatment using the different binder systems was compared in the light of the aforementioned two contaminants only. A set of physical tests (unconfined compressive strength (UCS)), chemical tests (NRA leachability) and micro-structural examinations (using scanning electron microscopy (SEM), and X-ray diffraction (XRD)) were used to evaluate the relative performance of the different binder mixes in treating the drill cuttings. The results showed that the observed UCS covered a wide range of values indicating various feasible end-use scenarios for the treated cuttings within the construction industry. The teachability results showed the reduction of the model drill cuttings to a stable non-reactive hazardous waste, compliant with the UK acceptance criteria for non-hazardous landfills: (a) by most of the 30% and 20% binders for chloride concentrations, and (b) by the 20% and 30% of compost-PC and CKD-PC binders for the Red Sea cuttings. The 20% and 30% compost-PC and CKD-PC binders successfully reduced the leached oil concentration of the North Sea cuttings to inert levels. Copyright 2007, Society of Petroleum Engineers.
