The mental health needs of physically disabled persons: Their perspective.

Evaluated disabled persons' perceptions of the types of problems experienced by the disabled population and the extent of this population's need for psychological services. 145 severely physically disabled former clients of a state rehabilitation commission responded to a questionnaire. Data show that 55% of Ss were aged 16–29 yrs, while 88% were 55 yrs old or less. 61.3% of Ss were males; 41% of Ss were married, 13% were divorced, 8% were separated, and 36% were single. 75% reported substantial need; 8% felt there was minimal or no need. Perceived problem areas included personal/emotional, organic/biological, marital/family, and vocational/career planning. Results suggest that this group of consumers perceives that there is a significant need for mental health services among individuals who are physically disabled.

A study of the effects of group family play on family relations.

Examined the differences in family relations, as measured by Beaver's Self-Report Family Inventory (W. R. Beavers and R. B. Hampston, 1990), between families participating in specified group family play and those not participating. Ss in this study included 52 families consisting of 134 family members. The researcher used random sampling to assign the families to 4 groups according to the Solomon Four Group Design. Ss participating in group family play attended 7 session, 6 sessions included an interaction game. Findings show that family play can be effective in improving family relations and that problem skills can be practiced and developed in a non-threatening, engaging intervention such as family play. Experimental groups showed significant improvement in family relations, differences could not have been due to testing effects or maturation. The findings support the use of family play in group settings in both prevention and therapeutic milieus. Implications are discussed.

Lexical effects on the phonetic categorization of speech: The role of acoustic structure.

This study examines the extent to which acoustic parameters contribute to lexical effects on the phonetic categorization of speech. Experiment 1 was designed to replicate previous findings. Two test continua were created varying in voice onset time. Results of both identification and reaction time (RT) range data showed an effect of lexical status at the phonetic boundary, but only in the slowest RT ranges, suggesting that lexical effects on phonetic categorization are postperceptual. Experiment 2 explored whether the lexical effect would emerge when the stimulus continua more nearly approximated the parameter values of natural speech. Both identification and RT range data indicated that the lexical effect disappeared. These results suggest that without attention to the acoustic structure of the stimuli, the role of top–down processing in phonetic categorization may be overemphasized.

Long-Term Educational Interventions After Traumatic Brain Injury in Children.

Objectives: To track educational interventions received by children with traumatic brain injury (TBI), examine factors associated with placement in special education, and explore the concordance of placement with children's needs. Methods: Interventions were monitored in 42 children with severe TBI, 42 with moderate TBI, and 50 with orthopedic injuries only (ORTHO group). A baseline assessment was completed soon after injury. Follow-up assessments were conducted 6 and 12 months after the baseline and at an extended follow-up about 4 years postinjury. Results: Rates of special education were higher in the severe TBI group than in the ORTHO. Predictors of special education included TBI severity, socioeconomic status, and measures of pre- and postinjury child status. Several children with TBI with residual deficits who were in regular education prior to injury did not receive special education at the extended follow-up. Conclusion: Although special education is frequently provided for several years after severe TBI, existing programs are of limited scope.

Development of a polymerase chain reaction assay for detection of three canola transgenes

Many countries are developing or implementing regulatory requirements to monitor for the presence of genetically modified (GM) materials in seeds, grain, and derived food products using DNA and protein-based methods. There is no published report on the detection of different GM transgenes in canola, and this study is aimed at developing qualitative PCR methods for the three major GM transgenes commercially available in canola. Primer sequences were generated from Gen-Bank and previously published information to develop a polymerase chain reaction (PCR) detection method for Roundup Ready (glyphosate tolerance, GT73 event), Liberty Link (glufosinate ammonium tolerance, HCN92 event), and BX (Bromoxynil tolerance, OXY235 event) canola varieties. On using PCR, two primer pairs for each of the GT73 and HCN92 and one primer pair for OXY235 amplified specific amplicons for the three GM transgenes. All three GM transgenes were detected simultaneously by multiplexing the five primer pairs in a single PCR reaction. Multiplexing of the five primer pairs for DNA prepared at 1% (one GM seed in 99 non-GM seeds) and 0.5% (one GM seed in 199 non-GM seeds) levels generated the expected DNA fragments for GT73, HCN92, and OXY235. This information will lay the groundwork for the development of a quantitative PCR assay for canola transgenic events.     

Thermal expansion coefficient of ZnSe crystal between 17 and 1080 °C by interferometry

The thermal expansion of ZnSe was measured by Fabry-Perot interferometry from 17 to 1080 °C during the heat-up of a seeded crystal growth experiment of ZnSe. The measured thermal expansion follows the two-step heating schedule very well. A single linear interpolation between the measured thermal expansion at 17 and 1080 °C gives a value for the thermal expansion coefficient, a as 4.95 × 10^− 6 °C^− 1. The estimated errors associated with a give its range of 4.60 to 4.99 × 10^− 6 °C^− 1.     

Blood pressure reactivity and cognitive function in the Baltimore Longitudinal Study of Aging.

Objective: Several blood pressure indexes of autonomic dysregulation, including stress-induced blood pressure responses (i.e., reactivity), have been associated previously with stroke, silent cerebrovascular disease, and decreased cognitive function. Design: The authors examined the cross-sectional relations among systolic blood pressure (SBP) and diastolic blood pressure (DBP) reactivity and cognitive function in a sample of stroke- and dementia-free older adults (n = 73, 53% male, 72% Caucasian, mean age = 70.14 years) from the Baltimore Longitudinal Study of Aging. Main Outcome Measures: Age, education, baseline, and reactive blood pressure levels were regressed on cognitive test scores measuring the domains of attention, learning and memory, verbal functions/language skills, and perceptuo-motor speed. A Bonferroni correction was employed and results significant at the standard p     

Security through Information Risk Management

Although security professionals have long talked about risk, moving an organization from a "security" mindset to one that thoughtfully considers information risk is a challenge. Managing information risk means building risk analysis into every business decision. The authors explore how chief information security officers (CISOs) of large firms are working to move the conversation from security toward information risk. CISOs face many organizational challenges, but they widely agreement that action plans must include risk categorization, communication, and measurement.     

Effects of initial cell concentration,growth phase,and process parameters on the viability of Lactobacillus rhamnosus GG after spray drying

Abstract

During spray drying, probiotics encounter several stresses which can reduce their viability. To obtain powder with a sufficient amount of viable probiotics, we evaluated the effects of different process parameters, such as initial cell concentration and the bacterial growth phase, on the viability of the model probiotic Lactobacillus rhamnosus GG. Increasing the initial biomass did not positively impact bacterial viability after spray drying. For growth, we found that stationary grown bacterial cells were more resistant to the spray-drying process than mid-log grown cells, probably owing to an initiated stress response. Furthermore, a full factorial 3³ design was used to assess the influence of three different conditions of inlet temperature, feed rate, and atomizing air flow on the outlet temperature and bacterial viability after spray drying. As expected, inlet temperature had the largest influence on both outlet temperature and log-reduction in bacterial viability. An interaction effect was also observed between feed rate and inlet temperature. Considering the viability of L. rhamnosus GG, the optimal outlet temperature ranged between 50 and 60?°C for obtaining powders with the lowest log-reductions in viability.     

Experiences in parallelising FLITE3D on the Cray T3D

FLITE3D is an unstructured multigrid Euler-CFD code, originally written by Imperial College, London, and Swansea University, and now developed by British Aerospace. In this paper we present our experiences at EPCC in porting FLITE3D to the Cray T3D MPP system. We discuss the operational requirements of a parallel production CFD code, and introduce the PUL-SM static mesh runtime library. We present performance results for the parallel FLITE3D Euler flow solver running on the UK National Supercomputing Service T3D, and echo our belief that massively parallel systems are a natural tool for commercial CFD modelling today.
