Typical intellectual engagement and personality: Reply to Rocklin (1994).

T. Rocklin (see record 1994-29650-001) examined the relations between M. Goff and P. L. Ackerman's (see record 1993-13529-001) measure of typical intellectual engagement (TIE) and a personality test measure of Openness. Rocklin's arguments are examined in the context of 3 themes: philosophical issues, TIE and Openness from a facet perspective, and the bandwidth-fidelity dilemma. Although Rocklin raised important issues about these constructs, it is demonstrated that measures of TIE and Openness, although significantly related, are theoretically and empirically distinguishable.

Spatiotemporal boundary formation: Boundary, form, and motion perception from transformations of surface elements.

Continuous surface boundaries, object shape, and global motion can be perceived from information that is fragmentary in both space and time. The authors report investigations indicating that accretion and deletion of texture is only 1 member of a broader class of element transformations that produce boundaries, shape, and motion, through spatiotemporal boundary formation (SBF). Four experiments exploring SBF are reported. The 1st 3 examine the class of transformations producing SBF, indicating that local element changes in color, orientation, or location are all effective. A 4th experiment examines temporal constraints on SBF. Integration of local element changes to produce boundaries, form, and global motion appears to be confined to a 165-msec window. Two classes of spatiotemporal integration models are considered; the relation between SBF and other cases of boundary interpolation are discussed.

Judgments of social justice: Compromises between equality and efficiency.

Political economists agree that a trade-off exists between equality and efficiency. Using a hypothetical society paradigm, the mean income (representing efficiency) and income variability (representing equality) of distributions of wealth and the correlation between wealth and effort within a society were manipulated. Ss made all pairwise comparisons of distributions within societies of differing meritocracy. A "maximin" principle best described trade-off resolution strategies when effort and outcome were weakly linked: People maximized the minimum standard of living within a society. A compromise principle best described preferences when income was tightly linked to effort: People rejected distributions in which some citizens fell below the "poverty line" but maximized efficiency above this constraint. Ideological polarization was pronounced under moderate meritocracy; here liberals could focus on the role of chance and conservatives on the role of effort and ability.

Electron-Impact Cross Sections for Dipole- and Spin-Allowed Excitations of Hydrogen,Helium, and Lithium

Electron-impact excitation cross sections are presented for the dipole- and spin allowed transitions from the ground states to the np ²P states for hydrogen and lithium, and to the 1snp ¹P states for helium, n = 2 through 10. Two scaling formulas developed earlier by Kim [Phys. Rev. A 64, 032713 (2001)] for plane-wave Born cross sections are used. The scaled Born cross sections are in excellent agreement with available theoretical and experimental data.     

Damage and strain in pseudomorphic vs relaxed GexSi1−x layers on Si(100) generated by Si ion irradiation

We compare both the strain and damage that 100 keV Si irradiation at room temperature introduces in pseudomorphic and relaxed Ge_xSi_1−x films grown on Si(100) substrates. The ion range is such that the Si/Ge_xSi_1−x interface is not significantly damaged. The amount of damage produced in pseudomorphic and relaxed Ge_xSi_1−x layers of similar x for irradiation doses up to 2.5 × 10¹⁴ Si/cm² is the same, which proves that a pre-existing uniform strain does not noticeably affect the irradiation-induced damage. However, the irradiation-induced strain does depend on the pre-existing strain of the samples. Possible interpretations are discussed.

西九龙填海区概念规划竞赛

In April 2001,the Govemment launched the West Kowllon Reclamation Concept Plan Competition to invite conceptral proposals for the development of a prominent 40-hectare waterfront site at the southern tip of the West Kowloon Reclamation into am integrated arts,cultural and entertainment district.The objective of the Competition is ,through the development,to enhance Hong Kong＇s positions as Asia＇s premiere centre of arts,culture and entertainment and create a new look for Victoria Harbour.The Competition attracted 161 entries,of which 71 were from Hong Kong and 90 were from elsewhere,covering some 30conntries.Adjudication of the Competition entries was made by a 10-member panel of Jury,chaired by Lord Rothschild.     

Group therapy for adult women survivors of child sexual abuse: Differentiation of completers versus dropouts.

Examined intake profiles of 54 depressed women survivors of child sexual abuse presenting for a specialized group therapy program at a community mental health center. The 32 therapy completers were compared with the 22 dropouts. Both groups possessed extensive and severe childhood and adult abuse histories. Both were extremely socially disadvantaged and clinically impaired as measured on the Millon Clinical Multiaxial Inventory (MCMI). Dropouts were more likely to have been battered as children and to have been sexually abused only within the family. Completers were more likely to have been multiply offended both by intrafamilial and extrafamilial perpetrators. The groups differed in terms of marital status and extent of economic dependence on spouse. Dropouts appeared to be more actively enmeshed in the abuse cycle at the time of therapy.

Estimation three-dimensional motion of rigid objects from noisyobservations

An estimate is made of the motion of a rigid body from two noisy 2-D perspective projections using the least-squares method and the algebra of R.Y. Tsai and T.S. Huang (1984). The accuracy of the estimated motion parameters is influenced by the position of the features of the object used in the calculation. Four test variables are derived that indicate how the accuracy is affected, and they are used for discarding inaccurate estimates. Monte Carlo tests demonstrate the obtained accuracy
