Browsing and searching e-encyclopaedias
Educational websites and electronic encyclopaedias employ many of the same design elements, such as hyperlinks, frames and search mechanisms. This paper asks to what extent recommendations from the world of web design can be applied to e-encyclopaedias, through an evaluation of users' browsing and searching behaviour in the free, web-based versions of Encyclopaedia Britannica, the Concise Columbia Encyclopaedia and Microsoft's Encarta. It is discovered that e-encyclopaedias have a unique set of design requirements, as users' expectations are inherited from the worlds of both web and print

Skateboarding in Place: Creating and Reclaiming Namescapes Through Skatescapes
This exploration paper considers the sport/art/activity of skateboarding as it intertwines with spatial experiences, identities, and our personal and kinetic vernaculars. I try to understand what skateboarders, and Indigenous skateboarders especially, can teach us about alternative ways to understand space, place, and identity. I posit that skateboarding encourages spatial comprehension and landscape-use in particular ways, what I think of as a skatescape: a landscape as seen through skateboarders’ eyes. Through a skateboarding media and art lens, I reflect on some ways in which skateboarding influences narratives of place and belonging. I then consider these personal narratives and attempt to broaden the definition of a skatescape and in so doing speculate on how we create, share, and navigate our unique and personal spatial languages through movement and presence. Finally, I reveal that appreciating Indigenous skatescapes has illuminated a blindspot in my settler psyche: that up until recently I had not acknowledged fully that each and every spot I have ever skated was and is Indigenous land
The recognition and characteristics of effective executives
A population was derived of individuals in positions of
hierarchial importance from a variety of organizations whose
effectivness in their professional endeavors was apparent to
their peers outside the organization. Characteristics of
this select group were compared to those of populations of
individuals not necessarily recognized as particularly effective
but occupying positions of similar hierarchial rank.
Significant differences were found between the select group
and reference populations in the three broad categories examined
perception of the management function, leadership style, and
motivational needs. The select group interacted more with
the environment external to their own organizations, and most
significantly, are much more highly motivated by the need for
power (and have a much lesser need for close interpersonal
relationships) than the reference group.http://archive.org/details/recognitionchara00burlNaval Air Rework Facility, North IslandApproved for public release; distribution is unlimited
High Sensitivity Mass Spectrometric Quantification of Serum Growth Hormone by Amphiphilic Peptide Conjugation
Amphiphilic peptide conjugation affords a significant increase in sensitivity
with protein quantification by electrospray-ionization mass spectrometry. This
has been demonstrated here for human growth hormone in serum using
N-(3-iodopropyl)-N,N,N-dimethyloctylammonium iodide (IPDOA-iodide) as
derivatizing reagent. The signal enhancement achieved in comparison to the
method without derivatization enables extension of the applicable concentration
range down to the very low concentrations as encountered with clinical glucose
suppression tests for patients with acromegaly. The method has been validated
using a set of serum samples spiked with known amounts of recombinant 22 kDa
growth hormone in the range of 0.48 to 7.65 \mug/L. The coefficient of
variation (CV) calculated, based on the deviation of results from the expected
concentrations, was 3.5% and the limit of quantification (LoQ) was determined
as 0.4 \mug/L. The potential of the method as a tool in clinical practice has
been demonstrated with patient samples of about 1 \mug/L
