TL;DR: The overall findings indicate that treatment in methadone maintenance, therapeutic communities, and outpatient drug-free programs was effective in improving posttreatment performance with respect to drug use, criminality, and productive activities.
Abstract: The results of the treatment evaluation research based on the Drug Abuse Reporting Program (DARP) are summarized and discussed. The DARP is a data system containing almost 44,000 admissions during 1969 to 1973 to 52 treatment programs located throughout the United States and in Puerto Rico. The current report focuses on the findings of a number of interlocking posttreatment follow-up studies based on data for three independent samples representing admissions to this system. These data include a total of 4,627 interviews conducted 5 to 7 years after admission to the DARP, and an average of over 4 years after termination from treatment. The overall findings indicate that treatment in methadone maintenance, therapeutic communities, and outpatient drug-free programs was effective in improving posttreatment performance with respect to drug use, criminality, and productive activities. Significantly poorer outcomes were reported for outpatient detoxification programs and a group of comparison (intake only) clients.

TL;DR: The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011-2014 using the APOGEE spectrograph, which collects high-resolution (R ~ 22,500), near-IR (1.51-1.70 µm) spectra with a multiplexing (300 fiber-fed objects) capability as discussed by the authors.
Abstract: The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011–2014 using the APOGEE spectrograph, which collects high-resolution (R ~ 22,500), near-IR (1.51–1.70 µm) spectra with a multiplexing (300 fiber-fed objects) capability. We describe the survey data products that are publicly available, which include catalogs with radial velocity, stellar parameters, and 15 elemental abundances for over 150,000 stars, as well as the more than 500,000 spectra from which these quantities are derived. Calibration relations for the stellar parameters (Teff , log g, [M/H], [a/M]) and abundances (C, N, O, Na, Mg, Al, Si, S, K, Ca, Ti, V, Mn, Fe, Ni) are presented and discussed. The internal scatter of the abundances within clusters indicates that abundance precision is generally between 0.05 and 0.09 dex across a broad temperature range; it is smaller for some elemental abundances within more limited ranges and at high signal-to-noise ratio. We assess the accuracy of the abundances using comparison of mean cluster metallicities with literature values, APOGEE observations of the solar spectrum and of Arcturus, comparison of individual star abundances with other measurements, and consideration of the locus of derived parameters and abundances of the entire sample, and find that it is challenging to determine the absolute abundance scale; external accuracy may be good to 0.1–0.2 dex. Uncertainties may be larger at cooler temperatures (Teff < 4000 K). Access to the public data release and data products is described, and some guidance for using the data products is provided.

TL;DR: The results indicate that internal integration strengthens the positive impacts of external integration on both delivery and flexibility performance, but the theory is not supported for either quality or cost performance.

TL;DR: In this article, the results of a comparative study of two networks of small-to medium-sized manufacturing enterprises in the U.S. wood products industry are presented. But they do not consider the effect of the number of participants in each network.
Abstract: This article presents the results of a comparative study of two networks of small- to medium-sized manufacturing enterprises in the U.S. wood products industry. Qualitative and survey data were collected from a sample of active participants in each network as well as from a sample of firms that were not network members (market firms) in the same industry. Using both qualitative and network analysis methodologies, we developed a model and testable propositions concerning key aspects of network structure and outcomes.

TL;DR: In this article, the authors examine managers' incentives for withholding segment information under the Statement of Financial Accounting Standards (SFAS) No. 14 and the impact of SFAS No. 131 on analysts' information environment.
Abstract: Using retroactive disclosures required by Statement of Financial Accounting Standards (SFAS) No. 131, we examine managers' incentives for withholding segment information under SFAS No. 14 and the impact of SFAS No. 131 on analysts' information environment for a sample of firms that previously reported as single‐segment firms and initiated segment disclosure with SFAS No. 131. We examine this set of firms because they likely had the strongest incentives to withhold segment information and analysts potentially had the most to gain when these firms were forced to begin providing segment disclosures under SFAS No. 131. We find that these firms used the latitude in SFAS No. 14 to hide profitable segments operating in less competitive industries than their primary operations. However, we find no evidence to suggest that these firms used the latitude in SFAS No. 14 to mask poor performance. In contrast, our results suggest that by withholding segment information, these firms allowed themselves to appear as if th...
