Compilation of downward flux observations from sediment trap deployments in the Atlantic Ocean - Contribution to EURO-BASIN's Data integration

We provide a compilation of downward fluxes (total mass, POC, PON, BSiO2, CaCO3, PIC and lithogenic/terrigenous fluxes) from over 6000 sediment trap measurements distributed in the Atlantic Ocean, from 30 degree North to 49 degree South, and covering the period 1982-2011. Data from the Mediterranean Sea are also included. Data were compiled from different sources: data repositories (BCO-DMO, PANGAEA), time series sites (BATS, CARIACO), published scientific papers and/or personal communications from PI's. All sources are specifed in the data set. Data from the World Ocean Atlas 2009 were extracted to provide each flux observation with contextual environmental data, such as temperature, salinity, oxygen (concentration, AOU and percentage saturation), nitrate, phosphate and silicate.

Particle flux in the NE Atlantic as recorded by sediment traps

Downward particle flux was measured using sediment traps at various depths over the Porcupine Abyssal Plain (water depth ab. 4850 m) for prolonged periods from 1989 to 1999. A strong seasonal pattern of flux was evident reaching a maximum in mid-summer. The composition of the material changed with depth, reflecting the processes of remineralisation and dissolution as the material sank through the water column. However, there was surprisingly little seasonal variation in its composition to reflect changes in the biology of the euphotic zone. Currents at the site have a strong tidal component with speeds almost always less than 15 cm/sec. In the deeper part of the water column they tend to be northerly in direction, when averaged over periods of several months. A model of upper ocean biogeochemistry forced by meteorology was run for the decade in order to provide an estimate of flux at 3000 m depth. Agreement with measured organic carbon flux is good, both in terms of the timings of the annual peaks and in the integrated annual flux. Interannual variations in the integrated flux are of similar magnitude for both the model output and sediment trap measurements, but there is no significant relationship between these two sets of estimates. No long-term trend in flux is evident, either from the model, or from the measurements. During two spring/summer periods, the marine snow concentration in the water column was assessed by time-lapse photography and showed a strong peak at the start of the downward pulse of material at 3000 m. This emphasises the importance of large particles during periods of maximum flux and at the start of flux peaks. Time lapse photographs of the seabed show a seasonal cycle of coverage of phytodetrital material, in agreement with the model output both in terms of timing and magnitude of coverage prior to 1996. However, after a change in the structure of the benthic community in 1996 no phytodetritus was evident on the seabed. The model output shows only a single peak in flux each year, whereas the measured data usually indicated a double peak. It is concluded that the observed double peak may be a reflection of lowered sediment trap efficiency when flux is very high and is dominated by large marine snow particles. Resuspension into the trap 100 m above the seabed, when compared to the primary flux at 3000 m depth (1800 mab) was lower during periods of high primary flux probably because of a reduction in the height of resuspension when the material is fresh. At 2 mab, the picture is more complex with resuspension being enhanced during the periods of higher flux in 1997, which is consistent with this hypothesis. However there was rather little relationship to flux at 3000 m in 1998. At 3000 m depth, the Flux Stability Index (FSI), which provides a measure of the constancy of the seasonal cycle of flux, exhibited an inverse relationship with flux, such that the highest flux of organic carbon was recorded during the year with the greatest seasonal variation.

ACE research briefing paper 002: learning and adaptation in the business creation process

This year marks the completion of data collection for year three (Wave 3) of the CAUSEE study. This report uses data from the first three years and focuses on the process of learning and adaptation in the business creation process. Most start-ups need to change their business model, their product, their marketing plan, their market or something else about the business to be successful. PayPal changed their product at least five times, moving from handheld security, to enterprise apps, to consumer apps, to a digital wallet, to payments between handhelds before finally stumbling on the model that made the a multi-billion dollar company revolving around email-based payments. PayPal is not alone and anecdotes abounds of start-ups changing direction: Sysmantec started as an artificial intelligence company, Apple started selling plans to build computers and Microsoft tried to peddle compilers before licensing an operating system out of New Mexico. To what extent do Australian new ventures change and adapt as their ideas and business develop? As a longitudinal study, CAUSEE was designed specifically to observe development in the venture creation process. In this research briefing paper, we compare development over time of randomly sampled Nascent Firms (NF) and Young Firms(YF), concentrating on the surviving cases. We also compare NFs with YFs at each yearly interval. The 'high potential' over sample is not used in this report.

Structural And Surface Morphological Investigation Of Formation Stages Of Highly (002) Oriented Zno Films On Glass Substrates By Spray Pyrolysis Method

ZnO thin films were coated on amorphous glass substrate at various temperatures in the range 160-500 0C by spray pyrolysis method. The as deposited films were characterised by using XRD and SEM. Wurtzite phase of ZnO was formed at a substrate temperature of 400 0C, highly oriented (002) phase was developed with respect to increase of substrate temperature from 450 to 500 0C. Morphological and growth mode of these films were analyzed with respect to structural orientation of films from wurtzite to highly (002) oriented phase. Present study reveals that substrate temperature was one of the important parameters which determine the crystalline quality, population of defects, grain size, orientation and morphology of the films

Intersexualidad y derecho: análisis del concepto género en las sentencias de asignación de sexo (Análisis de las sentencias: T-477 de 1.995, SU-337 de 1.999, T-551 de 1.999, T-692 de 1.999, T-1390 de 2.000, T-1025 de 2.002, T-1021 de 2.003 y T-912 de 2.008)

Esta monografía estudia 8 casos de menores de edad intersexuales que han sido fallados por la Corte Constitucional. A partir de las discertaciones jurídicas hechas por los magistrados se pueden encontrar interesantes elementos para el estudio del concepto género y la postura que frente al mismo ha tomado la Corte en su jurisprudencia.

Proyecto SPA-74-002.

Crear, promover y potenciar actividades que fortalezcan el intercambio con sectores exteriores a la red INCIE-ICEs (Instituto Nacional de Ciencias de la Educación - Instituto de Ciencias de la Educación). Fortalecer la estructura de la red. Asistencia técnica a las actividades de investigación y perfeccionamiento del profesorado de los ICE y del INCIE. Estructurado en 3 partes: la primera, hace una descripción del proyecto SPA/74/002 del Programa de Naciones Unidas para el Desarrollo (PNUD) concebido para el Centro Nacional de Investigaciones para el Desarrollo de la Educación (CENIDE). En la segunda, se describen las principales actividades realizadas, tanto de relaciones externas a la red, como de actividades de la red. Por último, se hace una evaluación del proyecto y se incluye una serie de anexos con las actividades e investigaciones realizadas, proyectos asistidos, contribución hecha por el gobierno y el PNUD, relación de becarios, consultores y profesores asistentes que han participado, publicaciones y cursos de formación realizados y una nota explicativa sobre el plan del profesorado de 1977. La reducción de los créditos destinados a la investigación no ha supuesto ningún problema al haberse organizado un sistema más adecuado. Aunque el INCIE ha cuidado sus relaciones externas, sigue siendo un problema la asistencia a reuniones internacionales de forma continuada y debería realizarse una mayor coordinación en la formación del profesorado. Por otro lado, constituye otro problema la insuficiencia de espacios y salas para la realización de cursos, además de la escasez de personal técnicos. Aunque hay aspectos a mejorar, el fortalecimiento del INCIE durante la realización del proyecto ha sido importante y se ha conseguido una mayor flexibilidad en la organización económica-administrativa. Además, no han existido problemas en la coordinación de la ejecución del proyecto y el perfeccionamiento del profesorado ha sido importante.

Texas Health & Safety Code, Section 165.002 - Right to Breastfeed in Texas

The language used in Section 165.002 of the Texas Health and Safety Code renders breastfeeding women vulnerable and susceptible to harassment, discrimination, and persecution via the Texas Penal Code, Sec. 30.05 (Criminal Trespassing), Sec. 21.08 (Indecent Exposure), and Sec. 21.22 (Indecency with a Child). ^ The overall goal of this paper is to develop a solution to this problem via a proposed law or legislative action that offers protection and support for breastfeeding women who choose to nurse in public. Data to inform these recommendations were collected through a literature review and structured interviews with several breastfeeding stakeholders. A literature review of state and federal breastfeeding legislation was conducted to compare and contrast differences between existing legislation in the United States. Interviews were conducted with breastfeeding legislation stakeholders, which included state legislators who have been active in breastfeeding legislation, breastfeeding mothers, and representatives from the Central Texas Healthy Mothers Healthy Babies Coalition (Centex HMHB Coalition), Texas Breastfeeding Coalition (TXBF coalition), La Leche League International, and the Texas Business Association. Data from the literature and legislation reviews and interviews were transcribed and examined for common themes using qualitative data techniques. ^ Overall, most of the stakeholders came to a general consensus on three points, (1) breastfeeding women are supported by stakeholders within the community, (2) other legislation or penal codes should not override the right to breastfeed, and (3) the current breastfeeding legislation needs to be improved to adequately support breastfeeding women. The interviews with breastfeeding legislation stakeholders yielded two major recommendations for the improvement of Section 165.002 of the Texas Health and Safety Code: advocacy efforts to change the wording of the legislation and education to inform people about the legislation. ^ The right to breastfeed is an important public health issue in that it provides a host of health benefits for mothers and children, and is more economical and environmentally superior to alternative feeding methods. While breastfeeding in public is not illegal nor ever has been, adequate legislation is important to affirm this right for women so that they can confidently feed their children without embarrassment or harassment.^
