The Divine Clockwork: Bohr's correspondence principle and Nelson's stochastic mechanics for the atomic elliptic state

We consider the Bohr correspondence limit of the Schrodinger wave function for an atomic elliptic state. We analyse this limit in the context of Nelson's stochastic mechanics, exposing an underlying deterministic dynamical system in which trajectories converge to Keplerian motion on an ellipse. This solves the long standing problem of obtaining Kepler's laws of planetary motion in a quantum mechanical setting. In this quantum mechanical setting, local mild instabilities occur in the Kelperian orbit for eccentricities greater than 1/\sqrt{2} which do not occur classically.Comment: 42 pages, 18 figures, with typos corrected, updated abstract and updated section 6.

IOS ASSIMILATION STRATEGIES: AN EMPIRICAL APPRAISAL

Interorganizational information systems (IOS) are increasingly relied on to facilitate the electronic exchange of data among organizations. Though substantive progress by the research community toward understanding IOS technology has been made, one unattended issue is understanding more fully the efficacy of alternative management strategies for assimilating IOS into organizational processes. Referred to here as IOS assimilation strategies, these strategies may offer to management useful alternatives for planning for and proceeding with IOS implementation. Conceptually based on Keen's (1991) notions of "reach" and "range" regarding organizations' computing infrastructure, two IOS Assimilation Strategies are tested for their comparative effects on three efficiency and six effectiveness measures. The empirical results, based on data from forty-eight organizations of the Group Insurance industry and the nonparametric Friedman test for significance testing, indicate that a significantly different ranking on the efficiency measures occurs across groups inhering varying strengths of IOS use pursuant to the alternative IOS Assimilation Strategies. The results suggest that greater efficiency gains may obtain by pursuing a strategy to extend IOS range over IOS reach. Consequently, management is advised to weigh carefully which IOS benefits, in terms of efficiency and effectiveness, are more important for substantiating IOS investments, and to make decisions regarding IOS implementation accordingly.Information Systems Working Papers Serie

A DISCREPANCY-BASED MEASUREMENT APPROACH FOR DATA INTEGRATION

This paper presents a measurement instrument for diagnosing the level of data integration at the organization and organization subunit levels. Incorporating consideration for specific theoretical properties related to data integration into its design, the measurement instrument relies on a discrepancy (or gap) measure to adequately account for these properties. Data from forty-eight organizations of the Group Insurance industry are used to test the reliability and validity of the measurement instrument. The results suggest that the discrepancy measure, based on the difference between respondents' ideal (i.e. normative) and actual estimates of data integration, appears to be a valid indicator of data integration. However the efficacy of using a discrepancy measure, over the simpler use of its parts, must be considered in light of practical and theoretical considerations.Information Systems Working Papers Serie

Jet array impingement with crossflow-correlation of streamwise resolved flow and heat transfer distributions

Correlations for heat transfer coefficients for jets of circular offices and impinging on a surface parallel to the jet orifice plate are presented. The air, following impingement, is constrained to exit in a single direction along the channel formed by the jet orifice plate and the heat transfer (impingement) surface. The downstream jets are subjected to a crossflow originating from the upstream jets. Impingement surface heat transfer coefficients resolved to one streamwise jet orifice spacing, averaged across the channel span, are correlated with the associated individual spanwise orifice row jet and crossflow velocities, and with the geometric parameters

GENDER DIFFERENCES IN THE INFORMATION SYSTEMS MANAGERIAL RANKS: AN ASSESSMENT OF DISCRIMINATORY PRACTICES

This paper examines the extent to which gender discrimination is a force effecting the senior managerial ranks of the information systems (IS) occupation. While the employment trends of women in the IS occupation is encouraging, we present data which suggests that IS is not immune to the problems of gender discrimination. Analyzing data gathered by the Society for Information Management (SIM), we find several serious problems suggestive of discriminatory practices. First, a disproportionate majority of senior IS management is male. Second, women receive lower salaries than men even when controlling for age, education, job level and tenure within the organization.Information Systems Working Papers Serie

The Fight Against Money Laundering (2004), and Inflation Targeting

in the World Economy (2003). Authors ’ note: We thank Steve Weisman for very helpful comments on an earlier draft. This revision refl ects the 2011 replacement of Iran’s Oil Stabilization Fund with its National Development Fund as a member of the International Forum of Sovereign Wealth Funds. We have scored the latter as the successor of the former. © Peterson Institute for International Economics. All rights reserved. The term sovereign wealth fund (SWF) had not been coined a decade ago. By 2007, economists and the financial world were alternatively excited about or alarmed by the growing influence of these institutions, though in fact many of them had been around for decades. Politicians in countries in which the funds invested generally welcomed the additional financial resources from abroad while expressing concern about the motivations of investors and what they feared could be threat
