Research Data Management — Activities and Challenges Report on the Knowledge Exchange Workshop

Workshop Research Data Management – Activities and Challenges 14-15 November 2011, Bonn The Knowledge Exchange initiative organised a workshop to highlight current activities and challenges with respect to research data management in the Knowledge Exchange partner countries and beyond. The workshop brought together experts from data centres, libraries, computational centres, funding organisations, publishing services and other institutions in the field of research and higher education who are working to improve research data management and encourage effective reuse of research data. A considerable part of the programme was dedicated to sharing perspectives from these communities, leading to the development of a roadmap of practical actions for the Knowledge Exchange initiative, partner organisations and other stakeholders to progress over the next two years. On the first day, principal investigators and project managers from a great variety of recent projects shared their insights on objectives and methods for improving data management ranging from discipline-specific to more general approaches. A series of short presentations of selected projects was followed by an extensive poster session that functioned as a “trade fair” of current trends and activities in the field of research data management. Moreover, the poster session offered ample network opportunities for participants. The second day was dedicated to intensive group discussions looking at a number of data management challenges. First the most important findings from the "Surfboard for 'Riding the Wave'" report were presented. This included the state of the art on activities and challenges in the field of research data management. The subgroups will concentrate on the following key themes: funding, incentives, training and technical infrastructure. These discussions culminated in the identification of practical recommendations for future cooperation on practical as well as on strategic levels that should be taken forward by the KE partner organisations and beyond. These activities aim to improve the sustainability of services and infrastructures at both national and international levels.

Research Software Sustainability: Report on Knowledge Exchange Workshop

The report introduces software sustainability, provides definitions, clearly demonstrates that software is not the same as data and illustrates aspects of sustainability in the software lifecycle. The recommendations state that improving software sustainability requires a number of changes: some technical and others societal, some small and others significant. We must start by raising awareness of researchers’ reliance on software. This goal will become easier if we recognise the valuable contribution that software makes to research – and reward those people who invest their time into developing reliable and reproducible software. The adoption of software has led to significant advances in research. But if we do not change our research practices, the continued rise in software use will be accompanied by a rise in retractions. Ultimately, anyone who is concerned about the reliability and reproducibility of research should be concerned about software sustainability. Beside highlighting the benefits of software sustainability and addressing the societal and technical barriers to software sustainability, the report provides access to expertise in software sustainability and outlines the role of funders. The report concludes with a short landscape of national activities in Europe and outside Europe. As a result of the workshop steps will be explored to establish European coordination and cooperation of national initiatives.

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.

Knowledge Exchange RDM Training & Skills Workshop, 9-10 Feb 2016, London

In today’s changing research environment, RDM is important in all stages of research. The skills and know-how in RDM that researchers and research support staff need, should be nurtured all though their career. At the end of 2015, KE initiated a project to compare approaches in RDM training within the partnership’s five member countries. The project was structured around two strands of activity: In the last months of 2015 a survey was conducted to collect information on current practice around RDM training, in order to provide an overview of the RDM training landscape. In February 2016 a workshop was held to share successful approaches to RDM training and capacity building provided within institutions and by infrastructure. The report describes the outputs of both the analysis of the survey and the outcomes of the workshop. The document provides an evidence base and informed suggestions to help improve RDM training practices in KE partner countries and beyond.

Report from the Knowledge Exchange Event: Pathways to Open Scholarship

The report on the ‘Pathways to Open Scholarship’ conference, organised by Knowledge Exchange to celebrate its 10th anniversary, contains an overview of the views that invited speakers and experts in the audience expressed on Open Scholarship developments. Open Scholarship is not yet a reality of everyday research and education. The event reported on, addressed the concept of "open scholarship" by debating issues and key challenges with the aim to identify pathways forward. Four central themes which represent crucial dimensions of open scholarship have been explored: Benefits, risks and limitations of Open Scholarship; Success as a researcher; Technology; and Publishing and publication services. The report contains views, expectations, wishes and frustrations that experts have on open scholarship, as well as new and promising initiatives and approaches. The report is a starting point for future planning of KE activity and input for a range of consultation talks with respected experts and leaders in the research community in KE countries and beyond.

Exchange biased FeNi/FeMn bilayers with coercivity and switching field enhanced by FeMn surface oxidation

FeNi/FeMn bilayers were grown in a magnetic field and subjected to heat treatments at temperatures of 50 to 350 degrees C in vacuum or in a gas mixture containing oxygen. In the as-deposited state, the hysteresis loop of 30 nm FeNi layer was shifted. Low temperature annealing leads to a decrease of the exchange bias field. Heat treatments at higher temperatures in gas mixture result in partial oxidation of 20 nm thick FeMn layer leading to a nonlinear dependence of coercivity and a switching field of FeNi layer on annealing temperature. The maximum of coercivity and switching field were observed after annealing at 300 degrees C.

Estimates of the rates of mortality of yellowfin tuna in the Eastern Pacific Ocean derived from tagging experiments

ENGLISH: Tag release and return data for the Baja California and Gulf of Guayaquil areas were selected for this study because substantial numbers of returns resulted from these releases and because the effects of emigration are small in these areas. The returns of tags per unit of fishing effort for several experiments in each area were used to estimate the coefficients of total mortality and shedding. The coefficient of annual natural mortality was estimated to be less than 2.0, which is in agreement with a previous estimate of 0.8, but does not improve upon it. The estimates for the average coefficients of catchability are 2.02 X 10-3 for the Baja California area and 0.67 X 10-3 for the Gulf of Guayaquil area. SPANISH: Se seleccionaron para este estudio algunos da tos de liberación y retorno de marcas en las áreas de Baja California y el Golfo de Guayaquil debido a que cantidades substanciales de retornos resultaron de estas liberaciones y porque los efectos de migración son pequeños en estas áreas. Los retornos de marcas por unidad de esfuerzo de pesca de varios experimentos en cada área fueron empleados para estimar los coeficientes de mortalidad total y desprendimiento. Se estimó que el coeficiente de mortalidad natural anual fue inferior a 2.0, lo que está de acuerdo con una estimación anterior de 0.8, pero no la mejora. Las estimaciones de los coeficientes promedios de capturabilidad son 2.02 X 10-3 en el área de Baja California y 0.67 X 10-3 en el área del Golfo de Guayaquil. (PDF contains 58 pages.)

Estimates of the rates of shedding of dart tags from yellowfin tuna

ENGLISH: Return data for single-tagged fish and for double-tagged fish which had retained one or both tags were used to estimate the rates of shedding of dart tags from yellowfin tuna. The Type-1 shedding, which occurs immediately after release of the fish, is about 10 percent. The Type-2 shedding is assumed to be constant throughout the life of the fish after tagging; it occurs at an instantaneous rate of about 0.278 per year. SPANISH: Se emplearon los datos de retorno de peces marcados con una sola marca y de peces marcados con doble marca los cuales han retenido una o dos marcas para estimar las tasas de pérdida de las marcas de dardo de atunes aleta amarilla. El Tipo-l de pérdida, que ocurre inmediatamente después de haber liberado el pez, es aproximadamente del 10 por ciento. El Tipo-2 de pérdida se supone que sea constante durante la vida del pez después de marcado; ocurre en una tasa instantánea cerca de 0.278 por año. (PDF contains 24 pages.)

Entwicklung und Lage ausgewählter Fischbestände - Einschätzung des Internationalen Rates für Meeresforschung Ende 2000

During the autumn session of the ICES Advisory Committee for Fisheries Management (ACFM) the stock of the Arctic, Northern and Southern Shelf, North Sea and Skagerrak have been analysed and assessed, as well as the mackerel and horse mackerel, sardine, anchovy and Pandalus, eel and harp and hooded seals. For a number of stocks ICES recommends a reduction in fishing mortality. Moreover, ICES recommends for many stocks to establish recovery and management plans, to safe guarda continuous development of the stocks towards safe biological limits.

Die Lage der Fischbestände in Nordostatlantik, Nord- und Ostsee. Einschätzungen des Internationalen Rates für Meeresforschung im Frühjahr 2001

The spring session of ACFM gave advice for a number of stocks in the North Atlantic, North Sea and Baltic. The present assessment of the situation is given here for stocks of importance for the German fishery. These are: Blue Whiting: the stock size is rapidly decreasing due to high catches; ICES recommends a closure of the fishery. Herring (Atlanto-Scandian, Norwegian spring spawner): Stock is within save biological limits, weak recruitment of the recent years will lead to a further reduction of biomass. Herring (North Sea): revision of the assessment led to a different perception of the stock: SSB was in 2000 below Blim. Excellent recruitment will lead to an increase of SSB over Blim within this year, but ICES recommends to reduce fishing mortality on adults significantly. Herring (Baltic spring spawner in 22–24, IIIa): Still no increasing tendency is detectable. Herring (VIaNorth): stable. Redfish: generally further decreasing tendency observed, a reduction of the fishery is recommended. Signs of recovery visible only for two units. Greenland Halibut: State of the stock not quite clear, but slightly positive tendencies. The present fishing intensity should be reduced. Cod (Kattegat): Weak recruitment, outside safe biological limits. ICES recommends a closure of the fishery. Cod (22–24, Western Baltic): Stock situation unclear due to extensive migrations. F should be reduced by at least 10%.

Die lage der Fischbestände in Nordostatlantik, Nord- und Ostsee. Einschätzungen des Internationalen Rates für Meeresforschung im Frühjahr 2000

The spring session of ACFM gave advice for a number of stocks in the North Atlantic, North Sea and Baltic. The present assessment of the situation is given here for stocks of higher importance for the German fishery. These are: Blue Whiting: the stock is still relatively high, this, however, will not last very long, due to too intense fishing. Cod in Kattegat: stock is outside safe biological limits. No immediate recovery in sight. Cod in 22–24 (Baltic): stock is inside save biological limits. F, however, is above the recommendation of the IBSFC. Greenland Halibut: state of the stock not quite clear. The present fishing intensity seems to be sustainable. Herring (Atlanto- scandian, Norwegian spring spawner): stock is within safe biological limits, weak recruitment of the recent years will lead to a reduction of biomass. Herring: for Baltic spring spawner in 22–24 and IIIa still no increasing tendency detectable. North Sea Herring: further increasing tendency, with 900 000 t over B lim, good recruitment. Herring in VIa: stable. Redfish: generally decreasing tendency observed, a reduction of the fishery is recommended. Signs of recovery, however, visible for some units

Catch rates as indices of abundance of yellowfin tuna, Thunnus albacares, in the Eastern Pacific Ocean

ENGLISH: Catch and effort data from logbooks of tuna seiners were used to make estimates of catch per hour of searching for 1970-1980. The estimates were standardized using a regression model to make annual estimates of abundance adjusted for fishing mode, speed, capacity, use of aerial assistance, net dimensions, and sea-surface temperature. Inside the CYRA the standardized estimates for tuna schools associated with dolphins and those for schools not associated with dolphins showed a similar overall pattern of decline. The 1980 catch rates were about 300/0 of the 1970 rates, the decline being greater for the schools not associated with dolphins. Dolphin-associated schools outside the CYRA declined to about 60% of the 1970 levels. SPANISH: Se emplearon los datos de la captura y el esfuerzo de los cuadernos de bitácora de las embarcaciones cerqueras para hacer las estimaciones de la captura por hora de búsqueda correspondientes a 1970-1980. Se normalizaron estas estimaciones usando un modelo de regresión con el fin' de hacer las estimaciones anuales de la abundancia, ajustadas según la moda de pesca, velocidad, capacidad, uso de ayuda aérea, dimensiones de la red y temperatura de la superficie del mar. En el ARCAA las estimaciones normalizadas de los cardúmenes de atún asociados con delfines y aquellas de los cardúmenes no asociados con delfines, indicaron una pauta general similar de reducción. Las proporciones de captura de 1980, fueron cerca del 300/0 de las de 1970, encontrándose la mayor reducción en los cardúmenes no asociados con delfines. Los cardúmenes asociados con delfines, fuera del ARCAA, se redujeron en un 60% con respecto a los niveles de 1970. (PDF contains 79 pages.)

Analysis of variance and standardization of longline hook rates of bigeye (Thunnus obesus) and yellowfin (Thunnus albacares) tunas in the Eastern Pacific Ocean during 1975-1987

ENGLISH: Longline hook rates of bigeye and yellowfin tunas in the eastern Pacific Ocean were standardized by maximum depth of fishing, area, and season, using generalized linear models (GLM's). The annual trends of the standardized hook rates differ from the unstandardized, and are more likely to represent the changes in abundance of tunas in the age groups most vulnerable to longliners in the fishing grounds. For both species all of the interactions in the GLM's involving years, depths of fishing, areas, and seasons were significant. This means that the annual trends in hook rates depend on which depths, areas, and seasons are being considered. The overall average hook rates for each were estimated by weighting each 5-degree quadrangle equally and each season by the number of months in it. Since the annual trends in hook rates for each fishing depth category are roughly the same for bigeye, total average annual hook rate estimates are possible with the GLM. For yellowfin, the situation is less clear because of a preponderance of empty cells in the model. The full models explained 55% of the variation in bigeye hook rate and 33% of that of yellowfin. SPANISH: Se estandardizaron las tasas de captura con palangre de atunes patudo y aleta amarilla en el Océano Pacífico oriental por la profunidad máxima de pesca, área, y temporada, usando modelos lineales generalizados (MLG). Las tendencias anuales de las tasas de captura estandardizadas son diferentes a las de las tasas no estandardizadas, y es más que representen los cambios en la abundancia de los atunes en los grupos de edad más vulnerables a los palangreros en las áreas de pesca. Para ambas especies fueron significativas todas las interacciones en los MLG con año, profundidad de pesca, área, y temporada. Esto significa que las tendencias anuales de las tasas de captura dependen de cuál profundidad, área, y temporado se está considerando. Para la estimación de la tasa de captura general media para cada especie se ponderó cada cuadrángulo de 5 grados igualmente y cada temporada por el número de meses que contiene. Ya que las tendencias anuales en las tasas de captura para cada categoría de profundidad de pesca son aproximadamente iguales para el patudo, son posibles estimaciones de la tasa de captura anual media total con el MLG. En el caso del aleta amarilla, la situación es más confusa, debido a una preponderancia de celdas vacías en el modelo. Los modelos completos explican el 55% de la variación de la tasa de captura de patudo y 33% de la del aleta amarilla. (PDF contains 19 pages.)
