Some Thoughts on the Scottish Arbitration Code 2007
November 2007 saw the launch of the new Scottish Arbitration Code by the Scottish Branch of the Institute. This replaces the 1999 version of the Code, which was promulgated not only by the Branch but also by the Scottish Council for International Arbitration and the Scottish Building Contract Committee. The new Code is also known as the Scottish Arbitration Rules 2007. This is helpful, as individuals like myself will no longer need to explain to our foreign students why the âCodeâ has no actual legislative status, but only applies if adopted by the parties. The Code was originally designed to apply in the construction and engineering industries, and while it was ultimately decided that it could apply in all forms of arbitral proceedings, its origins may be detected in certain provisions. This short article does not seek to provide a comprehensive survey of the Code, but rather seeks to draw attention to noteworthy features and the questions which may be raised thereby
The oral-aboral axis of a sea urchin embryo is specified by first cleavage
Several lines of evidence suggest that the oral-aboral axis in Strongylocentrotus purpuratus embryos is specified at or before the 8-cell stage. Were the oral-aboral axis specified independently of the first cleavage plane, then a random association of this plane with the blastomeres of the four embryo quadrants in the oral-aboral plane (viz. oral, aboral, right and left) would be expected. Lineage tracer dye injection into one blastomere at the 2-cell stage and observation of the resultant labeling patterns demonstrates instead a strongly nonrandom association. In at least ninety percent of cases, the progeny of the aboral blastomeres are associated with those of the left lateral blastomeres and the progeny of the oral blastomeres with the right lateral ones, respectively. Thus, ninety percent of the time the oral pole of the future oral-aboral axis lies 45 degrees clockwise from the first cleavage plane as viewed from the animal pole. The nonrandom association of blastomeres after labeling of the 2-cell stage implies that there is a mechanistic relation between axis specification and the positioning of the first cleavage plane
Macromere cell fates during sea urchin development
This paper examines the cell lineage relationships and cell fates in embryos of the sea urchin Strongylocentrotus purpuratus leading to the various cell types derived from the definitive vegetal plate territory or the veg_2 tier of cells. These cell types are gut, pigment cells, basal cells and coelomic pouches. They are cell types that constitute embryonic structures through cellular migration or rearrangement unlike the relatively non-motile ectoderm cell types. For this analysis, we use previous knowledge of lineage to assign macromeres to one of four types: VOM, the oral macromere; VAM, the aboral macromere, right and left VLM, the lateral macromeres. Each of the four macromeres contributes progeny to all of the cell types that descend from the definitive vegetal plate. Thus in the gut each macromere contributes to the esophagus, stomach and intestine, and the stripe of labeled cells descendant from a macromere reflects the re-arrangement of cells that occurs during archenteron elongation. Pigment cell contributions exhibit no consistent pattern among the four macromeres, and are haphazardly distributed throughout the ectoderm. Gut and pigment cell contributions are thus radially symmetrical. In contrast, the VOM blastomere contributes to both of the coelomic pouches while the other three macromeres contribute to only one or the other pouch. The total of the macromere contribution amounts to 60% of the cells constituting the coelomic pouches
Music, social cohesion, and intercultural understanding: A conceptual framework for intercultural music engagement
Regional conflict, growing technological developments, and climate change have seen high migration rates, which are likely to rise. Discrimination and violence at the hands of host societies continue to threaten the well-being of immigrant communities, as well as wider social cohesion in migration destinations. The urgency of the situation has been highlighted in several international policy documents released since 2020 by the United Nations (UN) and related agencies. In response, we have seen a global movement of intercultural music ensembles intended to break down cultural barriers and explore sites of cultural intersection, yet the real-world benefits of such initiatives remain unclear. There is a need to further explore and understand how and when music can be used as an instrument or site for fostering inclusion, understanding, and cohesion between migrants and their host communities. On appraising the evidence, we propose a conceptual framework for explaining how different cultures can interact with each other through musical participation.</p

How safe is your playground? Analyzing soil in Scottish schools through a university outreach project
School pupils often perceive STEM subjects to be challenging; thus, in this project, an interactive, nationwide STEM investigation was designed to stimulate their interest. The âSoils in Scottish Schoolsâ project provided teachers with a flexible package of resources to allow them to enhance the profile and understanding of soil science of their pupils. This package included presentations, experimental procedures, activities, and monthly newsletters which could be adapted to the particular learning environment of their pupils. In the focal point of the project, teachers were supported to encourage their pupils to collect samples from their school ground which were then analyzed for copper, lead, and zinc levels. This year-long project also afforded teachers with the opportunity to develop the pupilsâ investigative skills through engagement with experiments in their own classrooms where they could engage with real data
Atlantic water variability on the SE Greenland continental shelf and its relationship to SST and bathymetry
Author Posting. Š American Geophysical Union, 2013. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Journal of Geophysical Research 118 (2013): 847â855, doi:10.1029/2012JC008354.Interaction of warm, Atlantic-origin water (AW) and colder, polar origin water (PW) advecting southward in the East Greenland Current (EGC) influences the heat content of water entering Greenland's outlet glacial fjords. Here we use depth and temperature data derived from deep-diving seals to map out water mass variability across the continental shelf and to augment existing bathymetric products. We compare depths derived from the seal dives with the IBCAO Version 3 bathymetric database over the shelf and find differences up to 300âm near several large submarine canyons. In the vertical temperature structure, we find two dominant modes: a cold mode, with the typical AW/PW layering observed in the EGC, and a warm mode, where AW is present throughout the water column. The prevalence of these modes varies seasonally and spatially across the continental shelf, implying distinct AW pathways. In addition, we find that satellite sea surface temperatures (SST) correlate significantly with temperatures in the upper 50âm (Râ=â0.54), but this correlation decreases with depth (Râ=â0.22 at 200âm), and becomes insignificant below 250âm. Thus, care must be taken in using SST as a proxy for heat content, as AW mainly resides in these deeper layers.Funding for this work came from National
