  • The original Bates-Watts framework applies only to the complete parameter vector. Thus, guidelines developed in that framework can be misleading when the adequacy of the linear approximation is very different for different subsets. The subset curvature measures appear to be reliable indicators of the adequacy of linear approximation for an arbitrary subset of parameters in nonlinear models. Given the specific mean shift outlier model, the standard approaches to obtaining test statistics for outliers are discussed. The accuracy of outlier tests is investigated using subset curvatures.

  • Bates and Watts (1981) have discussed the problems of reparameterizing nonlinear models in obtaining accurate linear approximation confidence regions for the parameters. A similar problem exists with computing confidence curves for fitted values or predictions. The statistical behavior of fitted values does not depend on the parameterization. Thus, as long as the intrinsic curvature is small, standard Wald intervals for fitted values are likely to be sufficient. Accuracy of linear approximation for fitted values is investigated using confidence curves.

  • The flight activities of Holotrichia morosa Watershouse and H. diomphaia Bates adults were monitored by blacklight traps for six years from 1984 to 1989. The flight activity of H. morosa adults was most prominent from late June to early August with a peak flight in mid July, and that of H. diomphalia adults mainly occurred from early May to late June of odd years with the peak flight dates varying year by year. The flight activities of the two species during the fight period became vigorous after moderate to heavy rainfalls. The overwintered adults of H. diomphalia seemed to begin flying when the daily mean temperature rose above $15^{\circ}C$. The ratios of the females to the total adults collected by the blacklight traps were 53.3% for H. morosa and 0% for H. diomphalia, although the female sex ratio of the latter species was 57.4% in the field.

  • Herein, 20 species of the ground beetles are reported from Korea. Of these, 5 species, Bembidion serorum (Netolitzky, 1934), Bembidion gebleri nakanei (Jedlicka 1965), Mastax thermarum egorovi (Lafer 1973), Pterostichus jankowskyi (Tschischerine 1897) and Pterostichus longinquus Bates, 1873 are listed for the first time from the Korean Peninsula. Bembidion shimoyamai reported by Paik (1998) and Microlestes imaii reported by Paik and lung (2003) are misidentifications of Bembidion grapii and M. schroederi Holdhaus, respectively.

  • This paper describes current work regarding two EC funded projects, MUTED and HELIUM3D whose objective is to produce an autostereoscopic display system which is well suited to domestic television applications. Both of these projects have common roots in a previous EC funded project (ATTEST) and both employ laser illumination and viewer head tracking.

  • Yan & Hanson [8] and Makate & Sattayatham [6] extended Bates' model to the stochastic volatility model with jumps in both the stock price and the variance processes. As the solution processes of finding the characteristic function, they sought such a function f satisfying $$f({\ell},{\nu},t;k,T)=exp\;(g({\tau})+{\nu}h({\tau})+ix{\ell})$$. We add the term of order ${\nu}^{1/2}$ to the exponent in the above equation and seek the explicit solution of f.

  • Japanese does not exhibit deontic-epistemic polysemy which is recognized among typologically different languages. Hence, in Japanese linguistics, it has been debated which of the two types of modality is more prototypical. This study brings Chinese learner's acquisition data of Japanese modality to bear on the question of which of the two types of modality is more prototypical, using the Competition Model (Bates and MacWhinney 1981). The Competition Model notion of 'cues' as processing strategy adopted by learners reveals the continuity/discontinuity between these two modality domains.
