Few investigators studying alcohol abuse among individuals with a severe mental illness (SMI) have examined predictors of posttreatment alcohol outcomes. In the present study, a multivariate approach based on a theoretical model was used to study the relationship between psychosocial factors and post-treatment-initiation alcohol use. Predictors of alcohol use outcomes were examined in 278 individuals diagnosed with a current schizophrenia-spectrum or bipolar disorder and an alcohol use disorder (AUD). At 6-months follow-up, 144 of 228 available participants (63%) had good clinical outcomes. The results of structural equation modeling indicated that type of pretreatment residential setting was directly related to treatment, with participants who lived in supervised settings (41%) reporting significantly more days of treatment (β = .34, p 相似文献

This paper proposes a method to determine iron in samples of fish feed and feces using ultrasound in the extraction of the
analyte and in subsequent quantification by flame atomic absorption spectrometry. Using HCl 0.10 mol L−1 as the extraction solution, the optimal conditions of extraction were found to be: granulometry of the sample <60 μm; a sonication
time of five cycles of 10 s and sonication power of 136 W. The method was applied in studies of the availability of iron in
four food sources used in the diet of Nile Tilapia. The results obtained with the proposed extraction method allowed us to
calculate the coefficients of apparent digestibility of iron in the food sources, which was not possible when using results
obtained from samples mineralized by acid digestion. 相似文献

Organic–inorganic hybrids obtained by in situ polymerization of aniline in silica/phosphonate matrix

A method for preparing organic–inorganic hybrids containing organophosphorus compounds, silica, and polyaniline (PANI) was
developed using sol–gel technique. This method allows the in situ synthesis of organic–inorganic hybrids by reacting tetraethoxysilane
(TEOS), aniline, initiator, organophosphorus compound in formic acid. The formic acid has multiple functions: as solvent and
acidic media for polymerization of aniline and reagent for sol–gel process. The use of an organophosphorus compound as coupling
agent and the introduction of a conductive polymer in silica matrix was investigated. 相似文献

This study investigated whether a behavioral economic index of the value of rewards available over different time horizons improved prediction of drinking outcomes beyond established biopsychosocial predictors. Preferences for immediate drinking versus more delayed rewards made possible by saving money were determined from expenditures prior to resolution attempts by problem drinkers with different help-seeking experiences (N = 144). As hypothesized, stable resolutions over a 2-year follow-up were associated with proportionally more preresolution discretionary expenditures on savings and less on alcohol compared with unstable resolutions. The relationship held regardless of help-seeking history, and preresolution drinking practices, problems, and income were similar across outcomes. The findings extend experimental work on behavioral economics and indicate that measuring monetary allocation improves prediction of outcomes.

In this note we study a fixed point iteration approach to solve algebraic Riccati equations as they appear in general two player Nash differential games on an infinite time horizon, where the information structure is of open loop type. We obtain conditions for existence and uniqueness of non‐negative solutions. The performance of the numerical algorithm is shown in an example. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

The effect of two slaughter methods (immersion in ice-water slurry and electrical stunning followed by ice slurry asphyxiation) on chemical and microbiological parameters of grass carp (Ctenopharyngodon idella) stored in ice for 20 days was evaluated. No differences in total volatile basic nitrogen (TVB-N), pH, carbohydrate or protein content of mucus were observed between the slaughter methods. Ice-slaughtered fish had lower bacteria counts at the beginning of storage, but higher counts than fish slaughtered by electricity at the end of storage (p < 0.05). However, no significant differences in the shelf life were observed between the slaughter methods evaluated (limit of acceptability – counts > 3 × 106 CFU g−1 – attained after 13–16 days). Results indicated that the chemical parameters evaluated have a limited applicability to assess the shelf life of grass carp stored in ice, since pH limit (6.8) was exceeded after 4 days, while TVB-N limit (30 mg%) was not attained after 20 days of storage. 相似文献

Outlines a psychological procedure aimed at improving the working relationship between a newly hired executive and the executive's reporting official. The "Executive Fit Rehearsal" (EFR) attempts to systematically engage the executive and reporting official in a dialogue designed to anticipate and overcome problems resulting from individual differences in personality, expectations, work styles, and communication patterns. The procedure supports consensus and mutual understanding. To assess the effectiveness of the procedure, evaluation forms were mailed to participants of 15 consecutive Executive Fit sessions. Ss' reactions to the EFR indicate that the process facilitated adjustment to the work setting and improved communications. Comments from subordinates were more uniformly positive, suggesting that the process may be most helpful for new employees. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

We present a complete characterization of the set of minimal solutions of a single linear Diophantine equation in three unknowns over the natural numbers. This characterization, for which we give a geometric interpretation, is based on well-known properties of congruences and we use it as the foundation of direct algorithms for solving this particular kind of equation. These direct algorithms and an enumeration procedure are then put together to build an algorithm for solving the general case of a Diophantine equation over the naturals. We also put forth a statistical method for comparing algorithms for solving Diophantine equations which is more sound than comparisons based on times observed for small sets of equations. From an extensive comparison with algorithms described by other authors it becomes clear that our algorithm is the fastest known to date for a class of equations. Typically the equations in this class have a small number of unknowns in one side, the maximum value for their coefficients being greater than 3. 相似文献
