Psychometric evaluation of the Reasons for Living Inventory.

Examined the factor structure and psychometric properties of the Reasons for Living Inventory (RFL; M. M. Linehan et al; see record 1983-20123-001) in a sample of college students with a range of suicidal ideation and behaviors. An exploratory factor analysis of the 48-item RFL extracted 6 factors, similar to those described by Linehan et al. All coefficients alpha and item–subscale correlations were adequate. Additional nonclinical normative data are presented. Multivariate analysis of variance (MANOVA) identified 3 significant discriminant functions for group separation. Correlational analyses provided information about the relationships between the RFL and other self-report measures of suicide risk and general psychopathology. Three RFL subscales were useful in predicting suicide risk and general psychopathology. Limitations and future research issues are discussed.

Variability across sources of performance ratings.

Examined the comparability of peer ratings, supervisor ratings, and self-ratings of counseling performance early in training. Earlier studies of the relationship of performance ratings from different sources have indicated some comparability across source of rating, particularly late in the training process. The results of the present study with 30 21–50 yr old graduate students enrolled in a prepracticum counseling methods course indicate considerable variability across sources of ratings used early in training. Implications and practical training strategies are discussed. (9 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The synergistic application of CBR to IR

In this paper we discuss a hybrid approach combining Case-Based Reasoning (CBR) and Information Retrieval (IR) for the retrieval of full-text documents. Our hybrid CBR-IR approach takes as input a standard symbolic representation of a problem case and retrieves texts of relevant cases from a document collection dramatically larger than the case base available to the CBR system. Our system works by first performing a standard HYPO-style CBR analysis and then using the texts associated with certain important classes of cases found in this analysis to seed a modified version of INQUERY's relevance feedback mechanism in order to generate a query composed of individual terms or pairs of terms. Our approach provides two benefits: it extends the reach of CBR (for retrieval purposes) to much larger corpora, and it enables the injection of knowledge-based techniques into traditional IR. We describe our CBR-IR approach and report on on-going experiments.This research was supported by NSF Grant no.

Structural correlation between cuticular hydrocarbons and female contact sex pheromone of German cockroachBlattella germanica (L.)

The structural relationships between the cuticular hydrocarbons and the contact sex pheromone of the female German cockroach,Blattella germanica, were investigated. Cuticular hexane extracts were separated into hydrocarbon and ketone fractions by TLC or silicic acid column chromatography. The ketone fraction (which contains the major contact sex pheromone component) was analyzed by GC-MS before and after reduction to ydrocarbon. In addition to 3,11-dimethyl-2-nonacosanone, 3,11-dimethyl-2-heptacosanone was also identified. Females have the 3,11- and 3,9-dimethyl C₂₇ and C₂₉ alkanes, but only the 3,11- isomer of the dimethylketones. Inddition to the hydrocarbon components previously reported, a number of new components were characterized. Although the ratios of cuticular hydrocarbons differ among nymphs, adult males, and adult females, they have qualitatively identical hydrocarbon profiles, suggesting that the production of the contact sex pheromone results from the sex-specific oxidation of 3,11-imethylalkanes to pheromone components by the female.

Effects of vegetable juice powder concentration and storage time on some chemical and sensory quality attributes of uncured, emulsified cooked sausages

ABSTRACT:  Uncured, no-nitrate/nitrite-added meat products can be manufactured with vegetable juice powder (VJP) and a starter culture containing Staphylococcus carnosus , resulting in quality and sensory attributes similar to traditional cured products. The 1st objective of this study was to determine the effects of varying concentrations of VJP and incubation times (MIN-HOLD) on quality characteristics, including lipid oxidation, color, and cured meat pigment concentrations, of emulsified-frankfurter-style-cooked (EFSC) sausages over a 90-d storage period. The 2nd objective was to compare residual nitrate and nitrite content resulting from different processing treatments and the 3rd objective was to assess sensory properties of finished products. Four EFSC sausage treatments (TRT) (TRT 1: 0.20% VJP, 30 MIN-HOLD; TRT 2: 0.20% VJP, 120 MIN-HOLD; TRT 3: 0.40% VJP, 30 MIN-HOLD; TRT 4: 0.40% VJP, 120 MIN-HOLD) and a sodium nitrite-added control (C) were used for this study. No differences for lipid oxidation (TBARS) between any TRTs and C or over time were observed. No differences ( P > 0.05) for CIE L * values were found between TRTs. CIE a * and reflectance ratio values revealed that TRTs 2, 4, and C were redder than TRTs 1 and 3 at day 0. Trained sensory intensity ratings for cured aroma, cured color, cured flavor, uniform color, and firmness determined that all but TRT 1 were similar to C. These results indicate a longer incubation time (120 compared with 30 min) was found more critical than VJP level (0.20% or 0.40%) to result in products comparable to a sodium nitrite-added control.     

Influence of stimulants on electrodermal studies in Fragile X syndrome

Attention Deficit Hyperactivity Disorder (ADHD) is seen in the majority of children with Fragile X Syndrome (FraX). Previous work has documented an enhanced sweat response to stimuli in children with FraX compared to controls utilizing electrodermal response (EDR) measures. The present study assesses the EDRs both on and off stimulants in 19 children with ADHD and FraX compared to 17 age- and IQ-matched control patients with ADHD and developmental delays. Although the baseline EDRs were comparable between FraX patients and controls, the patients with FraX had a significant decrease in EDR amplitude and number of peaks when treated with stimulants compared to controls. This suggests that patients with FraX are more responsive to the enhancement of inhibitory systems that occur with stimulant use for ADHD. The use of a quantifiable measure, such as EDR, is recommended in future studies of treatment efficacy.     

Influence of resin chemistry on water uptake and environmental ageing in glass fibre reinforced composites-polyester and vinyl ester laminates

Hand laid up glass fibre reinforced isophthalic polyester resin and transfer moulded vinyl ester resin composites were subjected to environmental ageing. Gravimetric measurements were performed on laminate samples exposed to air and distilled water at 30°C and 60°C. Complementary porosimetry measurements on the original and fully aged samples indicated significant changes in the structure arising on ageing. Blistering showed that hydrolysis and de-bonding at the fibre-matrix interface occurred in polyester laminate to a greater extent at 60°C than 30°C. Leaching of monomer residues led to an anti-plasticisation effect in vinyl ester laminate. The influence of the fabrication method on the ageing behaviour is observed through porosity measurements on aged samples.     

Equivalence in symbolic and nonsymbolic contexts: Benefits of solving problems with manipulatives.

Children's failure on equivalence problems (e.g., 5 + 4 = 7 + __) is believed to be the result of misunderstanding the equal sign and has been tested using symbolic problems (including "="). For Study 1 (N = 48), we designed a nonsymbolic method for presenting equivalence problems to determine whether Grade 2 children's difficulty is due to the presence of symbols or to a more fundamental misunderstanding of equivalence. Children's superior performance on nonsymbolic versus symbolic problems suggests that children fail to map their understanding of equivalence onto problems presented with the symbols of arithmetic. For Study 2 (N = 32), we implemented a within-subject design to assess whether experience with nonsymbolic problems would facilitate performance on symbolic problems. This hypothesis was confirmed. Exposure to nonsymbolic problems may have enabled children to map their successful concepts and strategies to symbolic equivalence problems.
