    Closely approximating second-order Møller–Plesset perturbation theory with a local triatomics in molecules model (2000)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 112 (2000), S. 3592-3601

    Notizen: A new ansatz for local electron correlation is introduced, which truncates double substitutions subject to a triatomics in molecules (TRIM) criterion. TRIM includes all double substitutions in which one occupied-virtual substitution is atomic while the other substitution can be nonlocal (a cubic number, before cutoffs). With an additional approximation, the TRIM second-order Møller–Plesset perturbation theory (MP2) model can be noniteratively solved; this is the model that is implemented. Results are shown for absolute energies of alkane and polyene chains, rotational barriers of substituted ethylenes and benzenes, and association energies of the water and neon dimers. Over 99.7% of the untruncated MP2 energy is recovered for the test cases, and the relative energies of small systems are in error by less than 0.1 kcal/mol. By contrast, a diatomics in molecules (DIM) truncation recovers about 95% of the full MP2 energy, and yields errors several times larger for relative energies. © 2000 American Institute of Physics.

    Intramonomer correlation contributions to first-order exchange nonadditivity in trimers (2000)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 112 (2000), S. 3159-3169

    Thema: Physik , Chemie und Pharmazie
    Notizen: An expression for the nonadditive first-order exchange contribution in terms of the one- and two-particle density matrices of the isolated monomers is given. This formula is used to derive the intramonomer correlation contribution to the first-order exchange nonadditivity with the density matrices of the isolated monomers computed at the second-order Møller–Plesset level. As an illustrative example of the theory the trimer Ar2–HF is considered. It is shown that the correlation contribution is far from negligible, not only in relation to the corresponding first-order uncorrelated exchange, but also in comparison to the other three-body terms. Moreover, it is fairly anisotropic, so that it cannot be neglected in accurate calculations of nonadditive effects. © 2000 American Institute of Physics.

    Internal vs. external learning in new product development: effects on speed, costs and competitive advantage (2000)
    Oxford, Uk and Boston, USA : Blackwell Publishers Ltd
    R & D management 30 (2000), S. 0

    Thema: Wirtschaftswissenschaften
    Notizen: The purpose of this study was to investigate how different technology sourcing strategies throughout the new product development process influenced innovation speed, development costs, and competitive advantage. We studied 75 new product development projects from ten large, U.S.-based companies in several industries. Results indicated that: (1) more external sourcing during the early (i.e., idea generation) stage was related with lower competitive success; (2) more external sourcing during the later (i.e., technological development stage was related with slower innovation speed; and (3) development costs tended to rise with greater reliance on external sources of technology, but this result was not statistically significant.

    Why Some States Grow Faster than Others: New Growth Models for State Economic Policy (2001)
    Boston, USA and Oxford, UK : Blackwell Publishers Inc.

    Thema: Geographie , Wirtschaftswissenschaften
    Notizen: Recent studies have identified factors statistically related to differences in state economic growth. These findings relate to regional policy because they appear to identify political options that could then be justified as improving growth. This paper evaluates the reliability of these studies as policy guides. It finds that most statistical conclusions are fragile and are ttherefore risky policy guides Economic base theory performs well, and provides the most reliable state level policy options. These policies, however, have to be crafted carefully to avoid pitfalls associated with traditional (and perhaps unpopular) basic industries.

    Building an Integrative Model of Extra Role Work Behaviors: A Comparison of Counterproductive Work Behavior with Organizational Citizenship Behavior (2002)
    Oxford, UK and Boston, USA : Blackwell Publishers Ltd
    International journal of selection and assessment 10 (2002), S. 0

    Notizen: Researchers have recently drawn attention to performance elements that extend beyond task performance (often labeled as organizational citizenship behavior, or OCB). A second stream of research concerns detrimental, potentially destructive acts that hurt colleagues or organizations (labeled counterproductive work behavior, or CWB). Spector and Fox (in press) have proposed a model based upon conceptual parallels that may help connect these two disparate fields of research, using positive and negative emotions as intermediary variables between environmental conditions and extra-role work behaviors. The current study tested portions of the overall model, and found reasonable support for the components. Suggestions for further research designed to test the overall model are presented.

    Comorbidity and Taxometrics (2001)

    Thema: Psychologie
    Notizen: In the functional mental disorders, where conjointly definitive pathophysiology and etiology are unknown or nonexistent, a disease entity is specified syndromically, by the statistical relations of signs, symptoms, traits, tests, and other data. The very concept of co-morbidity becomes problematic, and its application to individual patients is difficult. Coherent cut kinetics, the taxometric method composed of multiple procedures (e.g., MAMBAC, MAXCOV, MAXSLOPE, MAXEIC, L-Mode) developed by Meehl and colleagues is a partial objective solution. The importance of the INKS condition, a concept from philosophy of science, is explained. Four situations of putative comorbidity are defined with explanations of how taxometric results would distinguish them.

    Narcissism and Counterproductive Work Behavior: Do Bigger Egos Mean Bigger Problems? (2002)
    Oxford, UK and Boston, USA : Blackwell Publishers Ltd

    Notizen: In accordance with the theory of threatened egotism and aggression, the relationships among narcissism, trait anger, job constraints and counterproductive work behavior (CWB) were explored in a questionnaire study. The results were supportive of the hypotheses that narcissism would relate to trait anger, job constraints, and CWB and that the relationship between narcissism and CWB would be mediated by anger. In addition, narcissism was found to moderate the relationship between job constraints and CWB, such that individuals high in narcissism reported more CWB when constraints were high, than individuals low in narcissism.

    Organizational Web Sites: Web Site Content and Style as Determinants of Organizational Attraction (2003)
    Oxford, UK : Blackwell Publishing
    International journal of selection and assessment 11 (2003), S. 0 
    Details

    Thema: Wirtschaftswissenschaften
    Notizen: Organizational web sites have become a primary source of information for job seekers. To date, no research has attempted to determine which aspects of organizational web sites most influence job-seeker attraction to an organization. The current paper reports the results of two studies that examined how perceptions of organizational web site content (compensation, organizational culture, and training opportunities) and style (aesthetics and usability) influence organizational attraction. The present findings demonstrate that both the content and style of organizational web sites are important precursors of organizational attraction. These findings are discussed both in terms of their practical implications for designing effective recruitment web sites and their implications for future empirical work on organizational recruitment activities.

    Distributed-feedback dye laser for picosecond ultraviolet and visible spectroscopy (2000)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 71 (2000), S. 1296-1305

    Notizen: We describe the design and operation of a tunable, picosecond laser system for use in time-resolved spectroscopic measurements in the visible and ultraviolet (UV) spectral region. The laser is designed for fine tuning and high wavelength stability. A Nd:YAG-pumped distributed-feedback dye laser (DFDL) generates pulses that are ∼100 ps in duration with a nearly transform-limited linewidth (∼5 GHz) at a 20 Hz repetition rate. The DFDL pulses are amplified in two bow-tie amplifiers, providing pulse energies of up to 3.0 mJ; the amplified pulses may be frequency doubled to the UV spectral region, providing up to 1.0 mJ. The DFDL wavelength is computer stabilized to within ±0.8 pm (±0.7 GHz, two standard deviations), allowing the wavelength to be stationed on a narrow atomic or molecular transition or permitting nearly continuous spectral scans. Application of the laser system to studies of OH energy transfer has been demonstrated; both laser-induced-fluorescence and degenerate-four-wave-mixing spectra have been recorded. © 2000 American Institute of Physics.
