Writing As A Survival Skill: How Neuroscience Can Improve Writing In Organizations
This article looks at the apparent paradox between the demand for strong writing skills and the lack of colleges of business that require their MBA students to complete writing courses. In the past, most approaches to teaching writing proved inadequate in producing graduates with the ability to write clearly, effectively, and efficiently. This article examines the implications of neurocognitive research on the reading process for the teaching of writing and ends with a set of 16 guidelines for teaching MBA students how to write well - principles that reach far beyond those specified in the SEC’s plain language guidelines
Spectro-electrochemical studies on luminescent complexes
This thesis is devoted to the characterisation of
redox-active metal-coordination complexes containing the
M-bipy chromophore, where M = metal and bipy = 2,2'-
bipyridine. Their electronic structural formulations
have been closely defined by comparative examination of
their absorption spectra in sequences of one-electron
related oxidation states. We have found that such a
series of related complexes offers a far greater chance
of successful analysis of the absorption spectra than if
the spectra are approached in isolation.The redox changes were generally achieved by
controlled electrogeneration using an optically transparent
thin layer electrode (O.T.T.L.E.) directly placed in the
spectrophotometer beam, so that the absorption spectra of
the unstable low-oxidation state complexes could be
unambiguously recorded. It was found necessary to
develop such 1spectroelectrochemical techniques' because
of the extreme sensitivity to oxygen of the reduced
complexes.In particular, we have shown that for reduced
metal-bipyridyl complexes the spectroelectrochemical
results can only be rationalised using a trapped-electron
model; for example the tris-bipy complexes should be
formulated as follows:
[M(bipy)₃]ᶻ⁺ = [M(bipy°)₃]ᶻ⁺,
[M(bipy)₃]⁽ᶻ⁻¹⁾⁺ = [M(bipy°)₂(bipy ⁻)]⁽ᶻ⁻¹⁾⁺, [M(bipy°)₃]⁽ᶻ⁻²⁾⁺
[M(bipy⁻)₃]⁽ᶻ⁻³⁾⁺. Thus we infer that in [M(bipy)₃]ᶻ⁺
and [M(bipy)₂L₂]²⁺ complexes the bipy ligands are noninteracting.We also discuss the metal-to-ligand charge transfer
excited state of [Ru(bipy)₃]²⁺ in which we find the
optically transferred electron to be exclusively located
on one ligand; best formulated as *[Ru(III)(bipy°)₂ (bipy⁻)]²⁺
This complex is, therefore, an example of a symmetric
D₃ ground state complex giving rise to a highly
unsymmetric excited state.The detailed analysis of characteristic electrode
potentials (for metal-based versus ligand-based reductions)
and the spectroscopic recognition of bipy° and
bipy⁻ chromophores have provided complementary and
consistent electronic structural elucidations, from
which molecular orbital energy diagrams can be usefully
constructed, and a simple correlation between central
metal charge and ligand-based reduction potentials can
be identified
Co-creating community solutions with customers : the case of First ScotRail
Creating customer solutions is said to embody the new service-dominant logic (Sharma, Iyer, & Evanschitzky, 2008; Tuli, Kohli, & Bharadwaj, 2007); the elaboration of solutions is likely to result from a value co-creation process involving actors from both the supply network and the customer network (Cova and Salle, 2008). This paper will explore how solution orientation can extend beyond B2B and B2C settings to include the co-creation of solutions for communities, consistent with a social marketing community partnership approach (Peattie & Peattie, 2009)
Effect of Ammonium-supplemented Seawater on Glutamine Synthetase and Glutamate Dehydrogenase Activities in Host Tissue and Zooxanthellae of Pocillopora damicornis and on Ammonium Uptake Rates of the Zooxanthellae
Host glutamine synthetase activity decreases in Pocillopora damicornis
(Linnaeus) following exposure of the coral to seawater containing elevated
ammonium (20 uM). Zooxanthellae isolated from these corals exhibited
lower ammonium uptake capacity and glutamine synthetase activity compared
with those from the control corals. Ammonium concentration of the surrounding
seawater had no effect on the NADPH-dependent glutamate dehydrogenase
activity in the host
Water quality between the Barron River/Trinity Inlet and Green Island and the effect of seasonal change
Nutrients and related water quality characteristics were measured at six sites along
a transect from the Barron River estuary to Green Island over a twenty-month
period.
The water column was generally well mixed and so depth was not a significant
source of variation. Overall, slightly higher nutrient concentrations tended to be
found at the two most inshore sites. FUrthermore, some elevated nutrient levels
were recorded right across the transect after periods of heavy rain and/or rough
weather. This elevation was most noticeable at the two inshore sites, suggesting
input from the Barron River discharge.· At Green Island there was no significant
increase over background levels in the mean levels of nutrients in the vicinity of the
sewage outfall, however relatively high chlorophyll a levels were recorded near to
the sewage discharge. These high chlorophyll a levels could indeed result from the
discharge of sewage effluent but further studies will need to be carried out in order
to confirm this

Using Ninhydrin to Detect Gravesoil
Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might have potential as a tool for the identification of clandestine graves. Juvenile rat (Rattus rattus) cadavers were buried in three contrasting soil types in Australian tropical savanna ecosystems and allowed to decompose over a period of 28 days. Soils were sequentially harvested and analyzed for NRN. Cadaver burial resulted in an approximate doubling (mean = 1.7 ± 0.1) in the concentration of soil NRN. This reaction has great potential to be used as a presumptive test for gravesoil and this use might be greatly enhanced following more detailed research
