A study of counseling center hiring practices: What does it take for a woman to be hired?

Examined the effect of raters' level of self-acceptance on the ratings of 3 types of candidates for counselor jobs: a "traditional," woman, a "feminist," and a candidate with sex unspecified. Ss were 81 male counseling center directors, associate directors, and assistant directors. Self-acceptance was measured by the Phillips Self-Acceptance Scale. Ss rated candidates on 6 variables on 5-point Likert-type scales. Results of 2 * 3 analyses of variance reveal that Ss with higher self-acceptance were more likely to evaluate all candidates as more competent to help clients. The feminist candidate was rated significantly higher than the other 2 candidates on potential to deal with a wide range of emotional problems and on preparation to develop outreach programs.

Short-term safety evaluation of processed calcium montmorillonite clay (NovaSil) in humans.

NovaSil clay (NS) provides significant protection from the adverse effects of aflatoxins (AFs) in multiple animal species by decreasing bioavailability from the gastrointestinal tract. It is postulated that NS clay can be safely added to human diets to diminish exposure and health risks from AF contaminated food. To determine the safety and tolerance of NS in humans and establish dosimetry protocols for long-term efficacy studies, a randomized and double-blinded phase I clinical trial was conducted. Volunteers (20-45 yr in age), were clinically screened for confirmation of their health status. Fifty subjects (23 males and 27 females) were randomly divided into two groups: The low-dose group received nine capsules containing 1.5 g/day, and the high-dose group received nine capsules containing 3.0 g/day for a period of 2?wk. NS capsules were manufactured in the same color and size and were distributed to each participant three times a day at designated sites where follow-up was taken to record any side effects and complaints. Blood and urine samples were collected before and after the study for laboratory analysis. All participants completed the trial and compliance was 99.1%. Mild GI effects were reported in some participants. Symptoms included abdominal pain (6%, 3/50), bloating (4%, 2/50), constipation (2%, 1/50), diarrhea (2%, 1/50), and flatulence (8%, 4/50). No statistical significance was found between the two groups for these adverse effects (p > 0.25). No significant differences were shown in hematology, liver and kidney function, electrolytes, vitamins A and E, and minerals in either group. These results demonstrate the relative safety of NS clay in human subjects and will serve as a basis for long-term human trials in populations at high risk for aflatoxicosis.     

The human homologue of the retroviral oncogene qin maps to chromosome 14q13

Chromosomal mapping of the human QIN gene (renamed FKH2 by the Human Genome Organization Nomenclature Committee) was initially accomplished by correlation of the presence of the QIN locus with specific chromosome regions in a rodent-human hybrid panel. This analysis revealed that the human QIN gene maps to chromosome region 14q11.2-->14q32, between the TCR and IGH loci. Further analysis by fluorescence in situ hybridization techniques with a human QIN genomic clone refined the human QIN gene localization to 14q13.     

A low-pass notch filter for bioelectric signals

Many bioelectric signals have relatively low-frequency content, but measurement devices are susceptible to power-line interference. The Type II Chebyshev low-pass filter can simultaneously perform the required low-pass filtering and removal of the narrowband interference. This filter has transfer-function zeros which result in zero gain (- infinity dB) at specific 'null' frequencies. A procedure for the low-pass filter design makes the first null frequency a design parameter so that the notch can occur at the interference frequency.<>     

Microstructure and Grain-Boundary Effect on Electrical Properties of Gadolinium-Doped Ceria

The microstructural evolution and grain-boundary influence on electrical properties of Ce_0.90Gd_0.10O_1.95 were studied. The nanoscale powders synthesized from a semibatch reactor exhibited 50% green density and 92% sintering density at 1200°C (∼200°C lower than previous studies). Impedance spectra as a function of temperature and grain size were analyzed. The Ce_0.90Gd_0.10O_1.95 with finest grain size possessed highest overall grain-boundary resistance; this contribution was eliminated at temperatures >600°C, regardless of grain size. The grain conductivity was independent of grain size and was dependent on temperature with two distinct regimes, indicative of the presence of Gd'_Ce− V _o^∘∘ complexes that dissociated at a critical temperature of ∼580°C. The activation energy for complex dissociation was ∼0.1 eV; the value for the grain-boundary was ∼1.2eV, which was size independent.     

A new cycle-based joint permutor design for multiple turbo codes

In this letter, a permutor design parameter, called the weight of a cycle through J-1 permutation matrices, for multiple turbo codes is introduced. Analogously to the single-permutor case of conventional turbo codes, we show the connection of the new parameter to the minimum distance of special classes of multiple turbo codes. In addition, simulation results are presented for multiple turbo codes based on the new design.     

NovaSil clay intervention in Ghanaians at high risk for aflatoxicosis. I. Study design and clinical outcomes

A 3-month double-blind and placebo-controlled, phase IIa clinical trial was conducted in Ghana to investigate the safety, tolerance and aflatoxin-sorption efficacy of dietary NovaSil (NS). Volunteers (507 subjects) were clinically screened to evaluate their general health, pregnancy status and blood AFB₁-albumin adduct levels. Of these subjects, 177 were randomly assigned to three groups: high-dose (HD), low-dose (LD) and placebo-control (PL) groups receiving 3.0, 1.5 and 0 g NS day^-1 in capsules. Trained study-monitors supervised NS capsule administration to participants and recorded side-effects daily. Physical examinations were performed monthly. Blood and urine samples were collected for laboratory analysis. Approximately 92% of the participants (162 of 177) completed the study and compliance rate was over 97%. Overall, 99.5% of person × time reported no side-effects throughout the study. Mild to moderate health events (∼0.5% of person × time) were recorded in some participants. Symptoms included nausea, diarrhea, heartburn and dizziness. These side-effects were statistically similar among all three groups. No significant differences were shown in hematology, liver and kidney function or electrolytes in the three groups. These findings demonstrate that NS clay is apparently safe and practical for the protection of humans against aflatoxins in populations at high risk for aflatoxicosis.     

Thermal aging of single-layer polymer light-emitting diodes composed of a carbazole and oxadiazole containing copolymer doped with singlet or triplet emitters

An electron-transporting monomer was synthesized that was structurally and energetically similar to the small molecule 2-biphenyl-4-yl-5-(4-tert-butylphenyl)-1,3,4-oxadiazole (tBu-PBD). The monomer was copolymerized with 2-(9H-carbazol-9-yl)ethyl 2-methylacrylate and the resulting copolymer was utilized in organic light emitting devices which employed fluorescent coumarin 6 (C6) or phosphorescent tris(2-phenylpyridine)iridium(III) [Ir(ppy)₃] emitters. The copolymer devices exhibited a mean luminance of ca. 400 and 3552 cd/m² with the C6 and Ir(ppy)₃ emitters, respectively, that was stable with thermal aging at temperatures ranging from 23 °C to 130 °C. Comparable poly(9-vinyl-9H-carbazole)/tBu-PBD blend devices exhibited more pronounced variations in performance with thermal aging.     

Preliminary evidence on the effectiveness of psychological treatments delivered at a university counseling center.

Treatment data from a university counseling center (UCC) that utilized the Outcome Questionnaire–45.2 (OQ-45; M. J. Lambert et al., 2004), a self-report general clinical symptom measure, was compared against treatment efficacy benchmarks from clinical trials of adult major depression that utilized similar measures. Statistical analyses suggested that the treatment effect size estimate obtained at this counseling center with clients whose level of psychological distress was above the OQ-45 clinical cutoff score was similar to treatment efficacy observed in clinical trials. Analyses on OQ-45 items suggested that clients elevated on 3 items indicating problematic substance use resulted in poorer treatment outcomes. In addition, clients who reported their relational status as separated or divorced had poorer outcomes than did those who reported being partnered or married, and clients reporting intimacy issues resulted in greater numbers of sessions. Although differential treatment effect due to training level was found where interns and other trainees had better pre–post outcome than did staff, interpretation of this result requires great caution because clients perceived to have complicated issues are actively reassigned to staff. More effectiveness investigations at UCCs are warranted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
