The effectiveness of a psychoeducational treatment program for reducing high-risk HIV transmission behaviors was compared with that of an information only group evaluated in a sample of 127 inpatients (aged 22–62 yrs), mostly African-American, on a drug abuse treatment unit. Both treatments were effective in increasing factual knowledge about AIDS, proficiency at demonstrating correct procedures for needle cleaning and condom use, and perceived susceptibility to and response efficacy for avoiding HIV infection. At posttreatment, Ss in the psychoeducation condition obtained higher scores on the condom demonstration test; however, at 1-mo follow-up, the performance of both groups on this test was equivalent. In terms of HIV knowledge, the psychoeducation group was superior at follow-up, but not at posttreatment. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Reading impaired first graders were given daily tutoring as a "first cut" diagnostic to aid in distinguishing between reading difficulties caused by basic cognitive deficits and those caused by experiential deficits. Reading achievement in most of these children was found to be within or above the average range after one semester of remediation. Children who were difficult to remediate performed below both children who were readily remediated and normal readers on kindergarten and first-grade tests evaluating phonological skills, but not on tests evaluating visual, semantic and syntactic skills. The results are consistent with convergent findings from previous research suggesting that reading problems in some poor readers may be caused primarily by phonological deficits.

Anxiety sensitivity is the fear of anxiety-related bodily sensations, which arises from beliefs that the sensations have harmful somatic, psychological, or social consequences. Elevated anxiety sensitivity, as assessed by the Anxiety Sensitivity Index (ASI), is associated with panic disorder. The present study investigated the relationship between anxiety sensitivity and depression. Participants were people with panic disorder (n?=?52 ), major depression (n?=?46), or both (n?=?37 ). Mean ASI scores of each group were elevated, compared to published norms. Principal components analysis revealed 3 factors of anxiety sensitivity: (a) fear of publicly observable symptoms, (b) fear of loss of cognitive control, and (c) fear of bodily sensations. Factors 1 and 3 were correlated with anxiety-related measures but not with depression-related measures. Conversely, factor 2 was correlated with depression related measures but not with anxiety-related measures. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

"A representative sample of the resident population of adults in the United States was interviewed about their feelings of distress in different life areas: perceptions of the self; symptoms of distress; adjustment in marriage parenthood, and work." Factor analysis of these data revealed the presence of 5 separate dimensions through which distress may be expressed: anxiety, unhappiness, sense of social inadequacy, lack of identity, and physical ill health. Men and women were distinguished by distress being expressed through physical ill health for men, psychological symptoms for women. The study indicates that psychological adjustment is multi-rather than unidimensional. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Mastering supramolecular self-assembly to a similar degree as nature has achieved on a subcellular scale is critical for the efficient fabrication of complex nanoscopic and mesoscopic structures. We demonstrate that active, molecular-scale transport powered by biomolecular motors can be utilized to drive the self-assembly of mesoscopic structures that would not form in the absence of active transport. In the presented example, functionalized microtubules transported by surface-immobilized kinesin motors cross-link via biotin/streptavidin bonds and form extended linear and circular mesoscopic structures, which move in the presence of ATP. The self-assembled structures are oriented, exhibit large internal strains, and are metastable while the biomolecular motors are active. The integration of molecular motors into the self-assembly process overcomes the trade-off between stability and complexity in thermally activated molecular self-assembly. 相似文献

Determined the effectiveness of single isolated vowels as auditory stimuli in eliciting perceptual illusory changes in ss, a phenomenon referred to by R. M. Warren (see pa, vol. 36:3gh49w) as the "verbal transformation effect." 3 vowels, /i/, /ae/, and /u/, were individually presented to a group of 24 19-24 yr. Old normal listeners in a single experimental session. Each vowel was repeatedly presented by means of headphones for a period of 5 min. Results indicate that single isolated vowels are capable of eliciting verbal transformations in normal listeners. However, the transformations reported often differed from those obtained in previous studies which used more phonetically complex auditory stimuli. The nature of the verbal transformations, average number of alternate forms perceived and transitions employed, and average number of repetitions of the stimuli prior to the onset of the ss' 1st verbal transformations are discussed. Comparisons with findings of previous investigations are provided. (french summary) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A method was developed for the rapid determination of the initial velocity of the desaturation of saturated fatty acids. In
the reaction, DPNH was a more efficient electron donor than TPNH. Fatdeficient rats have a 2.5-fold greater level of acyl
desaturase per milligram of liver microsomal protein than did animals fed lab chow. Increasing the chain length of the acyl
substrate from 10∶0 to 18∶0 increases the rate of monoene formation, but 19∶0 is desaturated at a rate lower than that for
15∶0. The energy of activation (Ea) for the overall desaturation reaction has been determined for 12∶0 through 19∶0. The Ea
values for desaturation of 13∶0 and 16∶0 are markedly lowr than for the other acids. An interaction between the alkyl chain
of the substrate and polyunsaturated acids of the microsomal membrane-bound phospholipids is postulated to explain the recurring
3-carbon pattern of the relative reaction rates of the various acyl substrates. 相似文献

The present research involved an item analysis of the Wesley Rigidity Inventory (1953) to determine its unidimensionality and the effect of age and intelligence. Factor analysis revealed orthogonally-related factors: rigidity in intellectual thinking, liking for established routine which was highly loaded with the factor of age, and a factor of appreciation of methodical behavior and details.
