Work after Covid19: What do our futures look like?
No full textThe Covid19 pandemic has had a profound effect on almost every aspect of our lives, but particularly on our ways of working. As many of us learnt how to ‘work from home’ (WFH) and upskill our technological skills in order to communicate and collaborate within and beyond our work organisations, we became used to the decoupling of work from physical space and embodied interaction. As we move slowly forwards, what will our ‘new ways of working’ look like?Chaired by Professor Pauline Leonard, with panellists, Dr Jane Parry, Lecturer in HRM and Organisational Behaviour, University of Southampton, Professor Steven Meers, Head of AI at Dstl, Lohan Presencer, Chairman, Ministry of Sound, and m.c. schraefel, Professor of Computer Science and Human Performance, University of Southampton
Total dissolved zinc in the upper water column of the subarctic north east Pacific
No full textTotal dissolved Zn concentrations are reported for winter and summer along the E-W line P transect and for summer along S-N line Z transect extending from Ocean Station Papa (OSP; 50[deg]N 145[deg]W) to the respective shelf waters. Surface-water 10 nM concentrations ranged from 0.04 nM in the open ocean to 0.9 nM at the Canadian shelf station. A clear gradient is evident, with dissolved Zn concentrations decreasing with increasing distance from shore along the E-W transect in both summer and winter. No consistent trend was observed along the S-N transect. Low concentrations of Zn (0.05-0.07 nM) were observed in near-surface water at OSP in winter. The vertical distribution of dissolved Zn is oceanographically consistent, showing a silicon-like vertical profile. Concentrations of silicic acid and dissolved Zn at depth are higher than those at equivalent depths in the Atlantic, as expected from deep-water circulation patterns and build-up in concentration of these elements. Dissolved Zn/Si ratios in the upper 200 m indicate a trend of decreasing with distance from shore, which infers a decoupling between dissolved Zn and silicic acid in the upper ocean. We hypothesise that the silicon-like profile of dissolved Zn is a result of recycling from relatively biologically resistant organic particulate phases, that leads to profiles very similar to those of dissolved silicon. Other than at two stations where there is very high primary production, there is no apparent horizontal relationship between total dissolved Zn and chlorophyll a or productio
The role of suspended particles in estuarine and coastal biogeochemistry
No full textThis chapter deals with the interactions of chemical species with suspended particulate matter (SPM), including nutrients, organic pollutants, metals, and radionuclides. The definition of SPM and its physical and chemical characteristics are introduced and followed by an evaluation of the distribution coefficient, Kd. The subsequent sections focus on both quantitative evaluations of SPM as a source and sink for chemical species, and the identification of mechanisms controlling these interactions. This chapter identifies how such interactions have been incorporated into estuarine-coastal models, including equilibrium and kinetic models. The chapter concludes with priorities for future SPM research.</p
Trace metals in the Antarctic soft-shelled clam Laternula elliptica: implications for metal pollution from Antarctic research stations
No full textThe concentrations of Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were measured in several soft-tissue types of the Antarctic soft-shelled clam, Laternula elliptica, which had been collected from Rothera Research Station, Adelaide Island, Antarctic Peninsula. Concentrations of Mn, Ni, Cr and Pb were significantly higher in the kidney than in any other soft tissue and highest concentrations of Cu were observed in the digestive gland. In general, the total tissue concentrations of heavy metals in L. elliptica were considered to be at baseline levels, except for Cu in organisms near the end of the runway. Copper concentrations were an order of magnitude greater (357 g/g dry weight) than baseline levels, suggesting anthropogenic contamination or an unidentified natural source. However, there was no indication of anthropogenic metal contamination occurring close to the sewage outfall at Rothera, which is a significant metal source. The results indicate that L. elliptica is a useful long-term biomonitor of heavy metal contamination in Antarctic coastal waters

2000 Sub-Librarians Meeting: Ace Atkins and M.C. Beaton
No full textThe Sub-Librarians planned and advertised a program with renowned science fiction and fantasy author Philip Jose Farmer. George Scheetz was instrumental in making that introduction. However, due to ill health, Farmer was unable to travel and had to cancel close to the program date.
However, on very short notice, Ace Atkins agreed to come to Chicago and speak to the group. Atkins had spoken to a very appreciative group of Sub-Librarians the previous year in New Orleans, and he gave another stellar performance in Chicago. He talked about his new book, Leaving\u27 Trunk Blues, which is another Nick Travers mystery, this one set in Chicago, from St. Martin\u27s Press.
St. Martin\u27s also stepped up and offered to have author M.C. Beaton join Ace as a speaker. M.C. Beaton is a pseudonym of Marion Chesney, who may be best known as the author of romance novels set during the English Regency. Her first detective story as M.C. Beaton came out for St. Martin\u27s in 1985. She has two series-one set in Scotland with Hamish Macbeth and one set in the Cotswolds with Agatha Raisin.
St. Martin\u27s generously provided copies of both authors\u27 books for signing after the program.
Marsha Pollak chaired the program, welcomed the audience, explained the change in speakers, called for toasts and introduced the authors
Drag it together with Groupie: making RDF data authoring easy and fun for anyone
No full textOne of the foremost challenges towards realizing a “Read-write Web of Data” [3] is making it possible for everyday computer users to easily find, manipulate, create, and publish data back to the Web so that it can be made available for others to use. However, many aspects of Linked Data make authoring and manipulation difficult for “normal” (ie non-coder) end-users. First, data can be high-dimensional, having arbitrary many properties per “instance”, and interlinked to arbitrary many other instances in a many different ways. Second, collections of Linked Data tend to be vastly more heterogeneous than in typical structured databases, where instances are kept in uniform collections (e.g., database tables). Third, while highly flexible, the problem of having all structures reduced as a graph is verbosity: even simple structures can appear complex. Finally, many of the concepts involved in linked data authoring - for example, terms used to define ontologies are highly abstract and foreign to regular citizen-users.To counter this complexity we have devised a drag-and-drop direct manipulation interface that makes authoring Linked Data easy, fun, and accessible to a wide audience. Groupie allows users to author data simply by dragging blobs representing entities into other entities to compose relationships, establishing one relational link at a time. Since the underlying representation is RDF, Groupie facilitates the inclusion of references to entities and properties defined elsewhere on the Web through integration with popular Linked Data indexing services. Finally, to make it easy for new users to build upon others’ work, Groupie provides a communal space where all data sets created by users can be shared, cloned and modified, allowing individual users to help each other model complex domains thereby leveraging collective intelligence
Iron and zinc enrichments in the northeastern subarctic Pacific: ligand production and zinc availability in response to phytoplankton growth
No full textIron- and zinc-enrichment experiments were carried out at Ocean Station Papa in the subarctic North Pacific. In iron-enriched treatments AI phytoplankton chlorophyll a (Chl a) increased 20-fold (9.7 mu g L-1) above the concentration on day zero. No stimulation of Chl a production or nitrate drawdown was observed on addition of zinc alone compared to the control. In the iron-enriched treatment, bioavailable zinc concentration decreased to 0.2 pmol L-1 lower than that which is known in culture experiments to limit some phytoplankton growth. Theoretical analyses suggest that this zinc concentration would cause diffusion-limited growth of large diatom cells present at the end of the incubation. Direct measurements of zinc-binding ligands indicate that the natural microbial planktonic assemblages have the ability to respond rapidly to conditions of high dissolved zinc concentrations. Rapid ligand production may be a mechanism by which certain phytoplankton reduce zinc toxicity or for maintaining zinc concentrations in the upper water column. Zinc-binding ligands were observed to be both produced and removed on the timescale of 1 d. We suggest that these zinc-binding ligands are produced to assist assimilation, particularly under iron-enriched conditions when concentrations of bioavailable zinc were extremely low, thereby alleviating the effects of zinc limitation
