The present study assessed drug use and the validity of self–reports of substance use among help–seeking veterans referred to a specialty clinic for the assessment of posttraumatic stress disorder (PTSD). Patients (n?=?341) were asked to provide a urine sample for use in drug screening as part of an evaluation of PTSD. Self–reports of substance use were compared with same–day supervised urine samples for 317 patients who volunteered to participate in a drug screening. Results suggested that self–reports were generally quite valid. Only 8% of the cases involved patients not reporting substance use detected by urine screens. A total of 42% of the participants were identified as using drugs of abuse (excluding alcohol) through self–report and urine drug screens. Among participants using drugs, PTSD diagnosis was significantly associated with greater marijuana and depressant use as compared with stimulant (cocaine and amphetamines) use.

There are variations in the extent to which particular types of inferences or activations are made during reading (G. McKoon & R. Ratcliff, 1992; M. Singer, 1994). In this study, the authors investigated the influence of reading purpose (for entertainment or study) on inference generation. Participants read 2 texts aloud and 2 texts for comprehension measures. Reading purpose did not influence off-line behavior (comprehension) but did influence on-line reader behavior (thinking aloud). Readers with a study purpose more often repeated the text, acknowledged a lack of background knowledge, and evaluated the text content and writing than did readers with an entertainment purpose. This pattern was stronger for the expository text than for the narrative text. Reading purpose, and possibly text type, affects the kinds of inferences that readers generate. Hence, inferential activities are at least partially under the reader's strategic control. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Two hundred fifty-six pregnant women who had quit smoking were classified into the precontemplation (PC), contemplation (C), preparation (PA), or action (A) stages of change for postpartum smoking cessation based on a 3-item algorithm assessing personal goals, self-efficacy, and smoking behavior. Logistic regression and event history analyses indicated group differences in return to smoking at 6 weeks and 3, 6, and 12 months postpartum. The percentage of women who returned to postpartum smoking was highest in the precontemplation stage and decreased with each subsequent stage, that is, at 6 weeks 83% of PCs, 64% of Cs, 35% of PAs, and 24% of As had returned to smoking. Results lend support for the stages of change for postpartum smoking abstinence. Stage-based interventions may be developed to assist women in maintaining abstinence postpartum.

Seit August 2006 breitet sich die Blauzungenkrankheit (engl. Bluetongue, BT) in Mitteleuropa aus, eine ausschlie?lich durch
Stechmücken (Gnitzen) übertragene und bis dahin in unseren Breiten nicht vorhandene Tierseuche von Haus- und Wildwiederk?uern.
Derzeit sind neben Deutschland bereits etliche weitere mitteleurop?ische L?nder betroffen. Die Infektion mit dem exotischen
Bluetonguevirus Serotyp 8 (BTV-8) wird durch heimische Culicoides-Mücken übertragene und ?u?ert sich in klinischen Symptomen, die teilweise auch auf andere bedeutende Seuchen hindeuten k?nnten,
so dass eine rasche labordiagnostische Abkl?rung erfolgen muss. Die staatliche Tierseuchenbek?mpfung versucht durch dauernde
überwachung, Handelsbeschr?nkungen und neuerdings auch durch Impfung der empf?nglichen landwirtschaftlichen Nutztiere die
Blauzungenkrankheit in Mitteleuropa einzud?mmen. 相似文献

A zinc vanadate with the formula Zn3(VO4)2·3H2O was synthesized by hydrothermal reaction of a gel of composition [(CH3CO2)2Zn·2H2O] : 0.5V2O5: 0.4 [1,3-diaminepropane] : 1.5 NaOH : 114 H2O, held at 170°C for 24 hours. The structure was determined ab initio by means of the EXPO direct methods program and refined with GSAS. The pale yellow solid crystallizes in the hexagonal space group P-6 with a= 6.07877(8), c= 7.1827(2) Å. The structure consists of vanadium tetrahedra bonded to distorted octahedral zinc atoms to create one dimensional columnar passageways for molecules. Though occupied by water in the as synthesized form, the passages could host other small molecules. 相似文献

Experimental Serra cheeses were manufactured from raw ewe’s milk and thistle flowers following a two-way factorial design.
The content of nitrogen soluble in water (WSN), in 2% trichloroacetic acid (2% TCA-N), in 12% TCA (TCA-N) and in 5% phosphotungstic
acid (5% PTA-N), and the pH and salt-in-moisture concentration were measured throughout the ripening period (sampling at 0,
7, 21 and 35 days) and the cheese-making season (sampling in November, February and May). Proteolysis in 35-day-old Serra
cheese was quantitatively high [average values of 34.6% and 11.9% for WSN/TN (total nitrogen) and 2% TCA-N/TN, respectively],
but qualitatively low (average values of 5.8% and 1.2% for 12% TCA-N/TN and 5% PTA-N/TN, respectively). The ratios WSN/TN
and 2% TCA-N/TN were lowest for cheeses ripened in February, whereas the ratio 12% TCA-N/TN was highest for cheeses ripened
in November. By 35 days of ripening, the average pH and salt-in-moisture concentration values were 5.2 and 4.8%, respectively.
No correlation was found to occur between the measured pH or salt-in-moisture concentration and the values of soluble nitrogen
fractions throughout the cheese-making season.

Strength in science & technology (S&T) is the foundation of a nation's economic power, so an effective, automated means of continually assessing this strength is critical to understanding a country's economic status. Six essays on global S&T assessment present various research frameworks, computational methods, issues, and results relative to knowledge mapping, scientometrics, information visualization, digital libraries, and multilingual knowledge management. 相似文献

Reviews studies that have tried to empirically confirm the effects of child sexual abuse cited in the clinical literature. In regard to initial effects, empirical studies have indicated reactions—in at least some portion of the victim population—of fear, anxiety, depression, anger and hostility, aggression, and sexually inappropriate behavior. Frequently reported long-term effects include depression and self-destructive behavior, anxiety, feelings of isolation and stigma, poor self-esteem, difficulty in trusting others, a tendency toward revictimization, substance abuse, and sexual maladjustment. The kinds of abuse that appear to be most damaging are experiences involving father figures, genital contact, and force. The effects of duration and frequency of abuse, age at onset, the child's reporting of the offense, parental reaction, and institutional response are also considered. The controversy over the impact of child sexual abuse is discussed. (49 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

[Correction Notice: An erratum for this article was reported in Vol 16(3) of Neuropsychology (see record 2007-17085-001). On Page 102, in the byline and in the author note, and on page 109 in the Rapport et al. (2001) reference, Sara Friedman's middle initial incorrectly reads "L." Her correct middle initial is "R."] Emotional competence and deficits that may disrupt interpersonal interactions were evaluated in 28 adults with attention-deficit hyperactivity disorder (ADHD) and 28 demographically equivalent controls. Participants completed tasks assessing affect recognition and experienced emotional intensity. Adults with ADHD performed worse in affect recognition than did adults without the disorder; however, the impairment was unrelated to gross perceptual processes, fundamental abilities in facial recognition, or attentional aspects of affect perception. Moreover, intensity of experienced emotion moderated affect recognition: Among controls, experienced emotion facilitated affect recognition. Among adults with ADHD, who reported significantly greater intensity, experienced emotion was inversely related to affect recognition. Results are consistent with theories of ADHD as a deficit in behavioral inhibition; yet, results may merely reflect a constellation of deficits associated with the disorder.

To investigate the extent to which the presence of their maternal grandmother might facilitate independent and adaptive responding, 2-year-old children were observed in a novel environment. Although the two-year-olds' extent of exploration and amount of time spent in a playroom were significantly greater when their mother was present than when an unfamiliar person was present, the grandmother's functional characteristics were on an intermediate level between those of the mother and those of the unfamiliar person. However, the more responsibilities that grandmothers reported customarily assuming for their grandchildren, the more similarly the children in the playroom reacted to their mothers and grandmothers. Extended involvement by a sensitive grandmother may enhance her grandchild's relationship with her. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
