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
