Planetary Candidates Observed by Kepler. III. Analysis of the First 16 Months of Data

Abstract: New transiting planet candidates are identified in 16 months (2009 May-2010 September) of data from the Kepler spacecraft. Nearly 5000 periodic transit-like signals are vetted against astrophysical and instrumental false positives yielding 1108 viable new planet candidates, bringing the total count up to over 2300. Improved vetting metrics are employed, contributing to higher catalog reliability. Most notable is the noise-weighted robust averaging of multi-quarter photo-center offsets derived from difference image analysis that identifies likely background eclipsing binaries. Twenty-two months of photometry are used for the purpose of characterizing each of the candidates. Ephemerides (transit epoch, T_0, and orbital period, P) are tabulated as well as the products of light curve modeling: reduced radius (R_P/R_★), reduced semimajor axis (d/R_★), and impact parameter (b). The largest fractional increases are seen for the smallest planet candidates (201% for candidates smaller than 2 R_⊕ compared to 53% for candidates larger than 2 R_⊕) and those at longer orbital periods (124% for candidates outside of 50 day orbits versus 86% for candidates inside of 50 day orbits). The gains are larger than expected from increasing the observing window from 13 months (Quarters 1-5) to 16 months (Quarters 1-6) even in regions of parameter space where one would have expected the previous catalogs to be complete. Analyses of planet frequencies based on previous catalogs will be affected by such incompleteness. The fraction of all planet candidate host stars with multiple candidates has grown from 17% to 20%, and the paucity of short-period giant planets in multiple systems is still evident. The progression toward smaller planets at longer orbital periods with each new catalog release suggests that Earth-size planets in the habitable zone are forthcoming if, indeed, such planets are abundant.

Building Corporate Associations: Consumer Attributions for Corporate Socially Responsible Programs

Abstract: Corporate social responsibility (CSR) is often used as a key criterion in gauging corporate reputation. This research examined the influence of consumers’ attributions on corporate outcomes in response to CSR. Researchers and managers have considered consumers’ beliefs about CSR initiatives to be simplistic, serving either economic ends or reflecting sincere social concerns. The results of two studies established that consumers’ attributions were more complex than traditionally viewed, mirroring many of the motives ascribed to companies by managers and researchers. Rather than viewing corporate efforts along a self- or other-centered continuum, consumers differentiated four types of motives: self-centered motives that are strategic and egoistic and other-centered motives that are values driven and stakeholder driven. Consumers responded most positively to CSR efforts they judged as values driven and strategic while responding negatively to efforts perceived as stakeholder driven or egoistic. Attributions were shown to affect purchase intent as well as mediate the structure of an offer.

Investigating information systems with action research

Abstract: Action research is an established research method in use in the social and medical sciences since the mid-twentieth century, and has increased in importance for information systems toward the end of the 1990s. Its particular philosophic context is couched in strongly post-positivist assumptions such as idiographic and interpretive research ideals. Action research has developed a history within information systems that can be explicitly linked to early work by Lewin and the Tavistock Institute. Action research varies in form, and responds to particular problem domains. The most typical form is a participatory method based on a five-step model, which is exemplified by published IS research.

The imposter phenomenon in high achieving women: Dynamics and therapeutic intervention.

Abstract: The term impostor phenomenon is used to designate an int ernal experience of intellectual phonies, which appears to be particularly prevalent and intense among a select sample of high achieving women. Certain early family dynamics and later introjection of societal sex-role stereotyping appear to contribute significantly to the development of the impostor phenomenon. Despite outstanding academic and professional accomplishments, women who experience the imposter phenomenon persists in believing that they are really not bright and have fooled anyone who thinks otherwise. Numerous achievements, which one might expect to provide ample object evidence of superior intellectual functioning, do not appear to affect the impostor belief. Four factors, which contribute to the maintenance of impostor feelings over time, are explored. Therapeutic approaches found to be effective in helping women change the impostor self-concept are described.

Board composition from a strategic contingency perspective

Abstract: This study examined the association between corporations’environments, strategies, and past performance and the composition of their boards of directors as measured by size and outside director representation. The environment, strategy and past performance were viewed as posing a strategic contingency; each of these sets could determine the success or failure of the company. Data on 119 Fortune 500 industrial companies for the 1983-9 period were used. Canonical analysis showed that increased uncertainty of a firm's environment, use of external growth and diversification; reliance on leverage as a means of finance, and poor past financial performance were associated with large board size and increased outside representation in subsequent years. Most important, board composition was positively associated with future measurements of corporate financial performance.
