    The Russian entrepreneur: a study of psychological characteristics (1996)
    Bingley : Emerald
    International journal of entrepreneurial behaviour & research 2 (1996), S. 49-58 
    Details
    ISSN: 1355-2554
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Outlines the methodology and results of a study into entrepreneurism in the new Russian economy. Asks whether the Russian entrepreneur can be characterized as similar to entrepreneurs identified in research in Western economies. Discusses the results in the context of the debate on individual v. situational causes of entrepreneurial success. Claims it would be helpful to the promotion of business venturing in growing economies, if differences in entrepreneurial psychological profiles could not only be identified, but were indicative of the potential for training or socialization.

    Notes: In Britain in 1945, the politics of peace steered reconstructiontowards a static socio-economic base from which stemmed many laterplanning and social problems. Britain had emerged from six years of wareconomically weakened but with a clear social vision, an effectiveadministration and fully evolved plans for the transition from war topeace. The social vision including the ideal of full employment and theright to a local job and a local home. This placed the economy in aspatial stranglehold and denied it the flexibility needed to adapt tochanging global conditions. Draws on the British experience to suggestthat the understandable desire to replace in situ what has beendestroyed is doomed to fail and can prejudice the ability of futuregenerations to meet their own needs.

    Discrete-event dynamic systems: The strictly convex case (1995)
    Springer
    Annals of operations research 57 (1995), S. 45-63

    ISSN: 1572-9338
    Keywords: Discrete dynamic systems ; max-algebra
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics , Economics
    Notes: Abstract Given the observed outputg j of a discrete-event system, a classical problem is to find a matrix realisationg j =cA jb withA of least possible dimension. When the sequenceg j is convex and ultimately 1-periodic, a linear-time algorithm suffices to construct such a realisation over the algebra (R, max, +). When the transient is strictly convex, this realisation is minimal-dimensional.

    How lesioning the nucleus praeeminentialis affects electrolocation behavior in the weakly electric fish, Apteronotus leptorhynchus (1996)
    Springer
    Journal of comparative physiology 179 (1996), S. 353-361 
    Details
    ISSN: 1432-1351
    Keywords: Behavior ; Electric fish ; Electrolocation ; Feedback pathways ; Nucleus praeeminentialis dorsalis

    Topics: Biology , Medicine
    Notes: Abstract The ability to orient to and track moving electrolocation targets was assessed in normal Apteronotus leptorhynchus and in those with unilateral lesions of the nucleus praeeminentialis dorsalis. 1. Each fish was trained to hover between two vertical metal rods and track their movement. Two aspects of this behavior were measured: a) the hovering position of the fish relative to stationary rods; b) the latency between the onset of rod motion and the fish's tracking response. Control fish hovered midway between stationary rods, while lesioned fish hovered closer to the rod ipsilateral to the lesion. Response latency varied negatively with rod diameter in both sets of fish, and lesioned fish exhibited shorter latencies than control fish. While the response latencies of control fish were shortest when their starting position was midway between the rods, lesioned animals' latencies were shortest when they hovered closer to the rod ipsilateral to their lesion. 2. Control fish responded to the approach of a single metal ball to either side of the body with nearly equal latencies and fish-to-object distances. After lesioning, response latency increased and fish-to-object distance decreased for approaches to the side ipsilateral to the lesion; opposite changes occurred for contralateral approaches.

    A 12-Month Prospective Study of the Relationship Between Stress Fractures and Bone Turnover in Athletes (1998)
    Springer

    ISSN: 1432-0827

    Topics: Biology , Medicine , Physics
    Notes: Abstract. Bone remodeling may be involved in the pathogenesis of stress fractures in athletes. We conducted a 12-month prospective study to evaluate bone turnover in 46 female and 49 male track and field athletes aged 17–26 years (mean age 20.3; SD 2.0) 20 of whom developed a stress fracture. Baseline levels of bone turnover were evaluated in all athletes and monthly bone turnover levels were evaluated in a subset consisting of the 20 athletes who sustained a stress fracture and a matched comparison group who did not sustain a stress fracture. Bone formation was assessed using serum osteocalcin (OC) measured by human immunoradiometric assay and bone resorption by urinary excretion of pyridinium cross-links (Pyr and D-Pyr); high performance liquid chromatography and N-telopeptides of type 1 collagen (NTx) using ELISA assay. Athletes who developed stress fractures had similar baseline levels of bone turnover compared with their nonstress fracture counterparts (P 〉 0.10). Results of serial measurements showed no differences in average levels of Pyr, D-Pyr, or OC in those who developed stress fractures (P= 0.10) compared with the control group. In the athletes with stress fractures, there was also no difference in bone turnover levels prior to or following the onset of bony pain. Our results show that single and multiple measurements of bone turnover are not clinically useful in predicting the likelihood of stress fractures in athletes. Furthermore, there were no consistent temporal changes in bone turnover associated with stress fracture development. However, our results do not negate the possible pathogenetic role of local changes in bone remodeling at stress fracture sites, given the high biological variability of bone turnover markers and the fact that levels of bone turnover reflect the integration of all bone remodeling throughout the skeleton.

    The identical 5' splice-site acceptor mutation in five attenuated APC families from Newfoundland demonstrates a founder effect (1999)
    Springer

    Notes: Abstract. Inherited mutations of the APC gene predispose carriers to multiple adenomatous polyps of the colon and rectum and to colorectal cancer. Mutations located at the extreme 5' end of the APC gene, however, are associated with a less severe disease known as attenuated adenomatous polyposis coli (AAPC). Many individuals with AAPC develop relatively few colorectal polyps but are still at high risk for colorectal cancer. We report here the identification of a 5' APC germline mutation in five separately ascertained AAPC families from Newfoundland, Canada. This disease-causing mutation is a single base-pair change (G to A) in the splice-acceptor region of APC intron 3 that creates a mutant RNA without exon 4 of APC. The observation of the same APC mutation in five families from the same geographic area demonstrates a founder effect. Furthermore, the identification of this germline mutation strengthens the correlation between the 5' location of an APC disease-causing mutation and the attenuated polyposis phenotype.

    Notes: Abstract: We introduce a certain cellular algebra $ which is a quotient of the q-Schur algebra $ . This is naturally equipped with a canonical basis which is compatible with Lusztig's canonical bases for certain modules for the quantized enveloping algebra $ . We describe a diagram calculus for $ which makes calculations involving the corresponding canonical bases easy to understand.

    Measuring differences between overlapping but unpaired spatial surveys using a geographic information system (1996)
    Springer
    Environmental monitoring and assessment 43 (1996), S. 237-253 
    Details
    ISSN: 1573-2959
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract To compare the results from two overlapping but unpaired synoptic surveys, a method using a geographic information system is proposed. The new method uses a GIS to create (i) minimum convex polygons (MCP) enclosing each set of survey data and (ii) Voronoi tesselations assigning area weights to each datum. The pairs of MCP and Voronoi maps are overlaid to produce a mosaic of polygons each with one datum assigned from each survey. The differences between the pairs weighted by the polygon areas provides the basis for statistical testing. Area-weighted means and variances of paired differences are computed and a z-statistic measures the significance of differences for the whole intersection area. A cross-product autocorrelation statistic provides an assessment of the spatial distribution of differences. Alternate, conventional methods are compared with the new method: analysis of variance (ANOVA), analysis of covariance (ANCOVA), and contour overlays. The four methods were applied to the comparison of two macrobenthic surveys conducted in Lake Erie. Measures for five different taxa were examined. The ANOVA and ANCOVA methods found many significant differences between surveys. Both methods were judged inappropriate as sampling data are not expected to be drawn from normally-distributed populations in spatial surveys. Differences between surveys were detected but were difficult to assess using contour overlays. The new method only found a significant difference in one taxon, an expected difference as members of that taxon were absent from most sites in one survey.
