Creativity and class: Review essay

This essay offer a critical review of form of class analysis presented in the works of the economic geographer Richard Florida. In it we use the example of the sale of the New Zealand internet auction site Trade Me to the Australian media group Fairfax to illuminate some of the problematic features of Florida's work

Foundation for Heavy Lift - Early Developments in the Ares V Launch Vehicle

The Ares V Cargo Launch Vehicle (CaLV) is NASA's primary vessel for safe, reliable delivery of the Lunar Surface Access Module (LSAM) and other resources into Earth orbit, as articulated in the U.S. Vision for Space Exploration. The Ares V launch concept is shown. The foundation for this heavy-lift companion to the Ares I Crew Launch Vehicle (CLV) is taking shape within NASA and with its government and industry partners. This paper will address accomplishments in the Ares V Launch Vehicle during 2006 and 2007 and offer a preview of future activities

Panel: Launching a Journal in the ERA of Web 2.0 The Case of JSAIS

Based on a need for quality venues of scholarly work, the Southern Association for Information Systems voted, at their 2008 annual meeting, to sponsor an online scholarly journal. The journal will be a classical, peer reviewed journal. Its emphasis will be on originality, importance, and cogency of ideas, with a broad focus emphasizing various research methodologies and inclusive of interdisciplinary investigations. The intent is to publish articles that adhere to the highest scholarly research standards and be inclusive in the publication process. JSAIS will distinguish itself by closely working with authors to develop submitted work. The founding JSAIS committee is working to launch the journal in the very near future. However, to remain as inclusive as possible, the committee is investigating different ways in which the review process might be implemented. Several models are evolving in academic review methods. The purpose of this panel is to introduce those methods and identify ways they might be adapted to meet JSAIS needs. The panel will be asking for commentary from participants

To Go or Not to Go: Exploring brain activation during response inhibition reading tasks

Objective: Response inhibition is an understudied component of reading that aids in the selection of appropriate responses amidst complicated tasks. Our objective was to explore the contribution of brain regions associated with response inhibition processing in reading tasks that vary in difficulty of response inhibition. Method: Participants (N = 15) completed two go/no-go reading tasks while in a functional magnetic resonance imaging (fMRI) scanner, with the instructions to “name aloud the letter strings that spell a real word.” For the minimal response inhibition condition, the foils, which are stimuli that should not be repsonded to, were nonwords with unfamiliar spelling and sound (e.g., “bink”). For the maximal response inhibition condition, the foils were pseudohomophones with unfamiliar spelling but familiar sound (e.g., “pynt”). The following brain regions associated with decision-making processes were analyzed: the anterior cingulate cortex (ACC), the dorsomedial prefrontal cortex (DMPFC), the inferior frontal gyrus (IFG), the middle temporal gyrus (MTG), the middle occipital gyrus (MOG), and the posterior insula (PI). Results: Significant differences in activation within the nonword task were found for the DMPFC and the PI (the ACC approached significance). Significant differences in activation within the pseudohomophone task were found for the ACC, the MTG, and the PI. The IFG was found to be greatly activated for all words that had familiar phonemes (sounds). The MOG was found to be activated across all tasks. Conclusion: We provide evidence for differential response inhibition processing in the decision-making network during reading tasks. This work is a necessary step in better understanding response inhibition ability for individuals with and without reading impairments

American Cheese Society Cheese and Dairy Product Lexicon and Glossary

The ACS Cheese and Dairy Product Lexicon and Glossary aims to facilitate conversations across the supply chain of cheese by creating a credible, modern resource that provides a greater understanding of the myriad ways in which cheese is discussed and described. A “working group” of ACS staff and experts in dairy food science, cheesemaking, and cheesemongering were involved in compiling what will hereafter be referred to as the ACS Lexicon & Glossary. The objective was to codify the terminology used when talking about sensory characteristics and evaluating and selling cheese and fermented dairy products

Personalising laboratory medicine in the ‘real world’:assessing clinical utility, by clinical indication, of serum total B12 and Active-B12® (holotranscobalamin) in the diagnosis of vitamin B12 deficiency

BACKGROUND: Assessing the pre- and post-test probability of disease in the context of routine health care is challenging. We wished to study how test performance parameters relating to clinical utility vary by clinical indication in a ‘real-world’ setting. METHODS: The diagnostic accuracy of serum total B(12) and Active-B(12)® (holotranscobalamin) was evaluated in a primary care population, using serum methylmalonic acid as the reference standard. We used electronic requesting to establish the clinical indication for each request. Routine requests from primary care for serum total B(12) were included if creatinine was also measured and estimated glomerular filtration rate was at least 60 mL/min/1.73 m(2). RESULTS: Clinical indications included peripheral neuropathy (n = 168), anaemia (n = 168), cognitive decline (n = 125), suspected dietary deficiency (n = 76), other (n = 362). For peripheral neuropathy, the area under the receiver operator curve ± 95% confidence interval (AUC ± CI) was 0.63 (0.54–0.71) (P = 0.002) for total B(12) and 0.68 (0.60–0.77) (P < 0.0001) for Active-B(12)®. For anaemia, AUC ± CI was 0.56 (0.47–0.66) (P = 0.10) for total B(12) and 0.69 (0.59–0.78) (P < 0.0001) for Active-B(12)®. For cognitive decline, AUC ± CI was 0.54 (0.43–0.65) (P = 0.26) for total B(12) and 0.69 (0.58–0.80) (P = 0.0002) for Active-B(12)®. The pre–post-test change in probability of disease varied by clinical indication. CONCLUSION: Combining diagnostic accuracy studies and electronic testing in a ‘real-world’ setting allows clinical utility to be assessed by clinical indication. Wider application of this would permit more personalised laboratory medicine. In this study, diagnostic performance of total B(12) and Active-B(12)® varied across all indications. Active-B(12)® provided better discrimination, but this may have reflected the cut-offs used

The Time Local Convex Hull method as a tool for assessing responses of fauna to habitat restoration: A case study using the perentie (Varanus giganteus: Reptilia: Varanidae)

Understanding the behavioural responses of animals to habitat change is vital to their conservation in landscapes undergoing restoration. Studies of animal responses to habitat restoration typically assess species presence/absencehowever, such studies may be restricted in their ability to show whether restoration is facilitating the return of self-sustaining and functional fauna populations. We present a case study using VHF/GPS tracking of a young adult perentie (Varanus giganteus), to demonstrate the range of applications of the Time Local Convex Hull method of home-range construction in analysing the behavioural responses of fauna to habitat change and restoration. Presence/absence studies provide single point locations of an animal, and the Minimum Convex Polygon method provides an invariant estimate of habitat use across the whole home range. However, the Time Local Convex Hull method provides a useful method for assessing movement and behavioural responses of fauna to habitat change and restoration, and the specific habitat requirements for the long-term support of populations. The breadth and multidimensionality of data generated indicates strongly that understanding the complex interactions between animals and their environment is fundamental to their conservation in the face of ever-increasing rates of human-induced habitat change and degradation
