Economic consequences of accounting standards : The lease disclosure rule change

We examine capital structure changes to investigate the impact of SFAS No. 13 on lessees. While this accounting standard essentially rearranged capital lease disclosures (from footnotes to the balance sheet), mandated capitalization substantially altered key accounting ratios. Our results document a systematic substitution from capital leases to operating leases and nonleases sources of financing. In addition, lessees appear to reduce book leverage by increasing equity and reducing conventional debt. The magnitudes of these responses are cross-sectionally related to preadoption levels of footnoted capital leases.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27037/1/0000025.pd

The use of accounting information in bank lending decisions

This paper examines the impact of accounting information on the sequential judgements of experienced bank loan officers using realistic lending cases in an experimental setting. The findings suggest that loan officers reach a high level of confidence early in the lending process based on summarized accounting information and other general background data. When, later in the process, factors concerning the firm's financial plans and their underlying assumptions are varied, lenders adjust their confidence in whether or not to grant the loan in the expected directions, even when the subsequent evidence disconfirms their original positions.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28159/1/0000611.pd

Investigation of the Epitaxial Graphene/p-SiC Heterojunction

There has been significant research in the study of in-plane charge-carrier transport in graphene in order to understand and exploit its unique electrical properties; however, the vertical graphene–semiconductor system also presents opportunities for unique devices. In this letter, we investigate the epitaxial graphene/p-type 4H-SiC system to better understand this vertical heterojunction. The I–V behavior does not demonstrate thermionic emission properties that are indicative of a Schottky barrier but rather demonstrates characteristics of a semiconductor heterojunction. This is confirmed by the fitting of the temperature-dependent I–V curves to classical heterojunction equations and the observation of band-edge electroluminescence in SiC

Improved GaN-based HEMT performance by nanocrystalline diamond capping

As a wide-bandgap semiconductor, gallium nitride (GaN) is an attractive material for next-generation power devices. To date, the capabilities of GaN-based high electron mobility transistors (HEMTs) have been limited by self-heating effects (drain current decreases due to phonon scattering-induced carrier velocity reductions at high drain fields). Despite awareness of this, attempts to mitigate thermal impairment have been limited due to the difficulties involved with placing high thermal conductivity materials close to heat sources in the device. Heat spreading schemes have involved growth of AIGaN/GaN on single crystal or CVD diamond, or capping of fullyprocessed HEMTs using nanocrystalline diamond (NCD). All approaches have suffered from reduced HEMT performance or limited substrate size. Recently, a "gate after diamond" approach has been successfully demonstrated to improve the thermal budget of the process by depositing NCD before the thermally sensitive Schottky gate and also to enable large-area diamond implementation

Crowdsourcing hypothesis tests: Making transparent how design choices shape research results

To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen research teams independently designed studies to answer fiveoriginal research questions related to moral judgments, negotiations, and implicit cognition. Participants from two separate large samples (total N > 15,000) were then randomly assigned to complete one version of each study. Effect sizes varied dramatically across different sets of materials designed to test the same hypothesis: materials from different teams renderedstatistically significant effects in opposite directions for four out of five hypotheses, with the narrowest range in estimates being d = -0.37 to +0.26. Meta-analysis and a Bayesian perspective on the results revealed overall support for two hypotheses, and a lack of support for three hypotheses. Overall, practically none of the variability in effect sizes was attributable to the skill of the research team in designing materials, while considerable variability was attributable to the hypothesis being tested. In a forecasting survey, predictions of other scientists were significantly correlated with study results, both across and within hypotheses. Crowdsourced testing of research hypotheses helps reveal the true consistency of empirical support for a scientific claim.</div
