Effects of Sex on Peer Ratings of U.S. Army Rotc Cadets

The effects of sex of rater and sex of ratee on peer ratings were investigated. Subjects were U.S. Army ROTC cadets at a 6-wk. advanced training camp in 1985; 935 subjects were men and 373 were women. Male ratees received significantly (α = .01) higher peer ratings than the female ratees received. Male ratees received significantly (α = .01) higher peer ratings from male raters than from female raters. Female ratees received significantly (α = .01) higher peer ratings from female raters than from male raters. It is possible that men received higher ratings than women because there were more men doing the rating.

Effects of freezing to −196 °C and thawing on Setaria lutescens seeds

The effects of single and repeated freezing and thawing of Setaria lutescens seeds in liquid nitrogen were investigated. One freeze to −196 °C followed by a slow thaw, increased seed germination from 40 to 70%, but additional freeze-thaw cycles reduced germination to 30%. Using a scanning electron microscope, evidence was produced that seed coat cracking did not cause either initial increased, or subsequent reduced germination. Observations with a transmission electron microscope revealed that disruption of the integrity of lipid bodies accompanied increased damage from repeated freezing at −196 °C and thawing. Repeated freezing and thawing of seeds stored in liquid nitrogen should be done with care to avoid loss of the germplasm.

Prominent spermoderm patterns of Poaceae

Scanning electron microscopy studies of 60 genera and 118 species of the Poaceae revealed prominent spermoderm patterns. The most common patterns observed (with percent occurrence) were simple reticulate with straight walls (48.3%), simple reticulate with wavy walls (14.4%), and verrucate without pubescence (13.6%). No other pattern occurred in more than 10% of the species observed. Some genera possess common spermoderm patterns among species while others do not.

Pediatric type 2 diabetes mellitus complications: a systematic review of the literature

Abstract The incidence and prevalence of type 2 diabetes mellitus (T2DM) are increasing worldwide in the pediatric population. The increase has been attributed to obesity, lack of physical activity, improper diet, and family medical

Distress and Performance Appraisal Satisfaction

120 quality assurance engineers indicated how frequently job stressors, causing distress related to role ambiguity, role conflict, role overload, and career development, affected them at work. They also indicated their satisfaction with their most recent performance appraisal. Satisfaction with performance appraisal was significantly negatively correlated with each stressor.

Comparison ofDactylotenium Willd. andEleusine Gaertn. Spermoderm patterns

Seeds ofDactyloctenium Willd. andEleusine Gaertn. may be distinguished from each other by spermoderm patterns.Dactyloctenium seeds are transversed by ridges crossed by wavy lines forming a verrucated, reticulate pattern.Eleusine seeds have a pitted, tuberculate spermoderm pattern.

Letter to the editorAssociation of maternal fever during labor with neonatal and infant morbidity and mortality

Abstract Objective: To examine the association of intrapartum fever with infant morbidity and early neonatal (0–6 days) and infant (0–364 days) death. Methods: We carried out a retrospective cohort analysis among singleton live births in the United States for the period 1995–1997 using the National Center for Health Statistics linked birth-infant death cohort data. Results: Among the 11,246,042 singleton live births during the study period, intrapartum fever (at least 38C) was recorded in 1.6%. Intrapartum fever was associated with early neonatal (adjusted odds ratio [OR], 95% confidence interval [CI] for preterm and term infants respectively: 1.32; 1.11, 1.56 and 1.67; 1.14, 2.46) and infant (OR, 95% CI for preterm and term, respectively: 1.31; 1.14, 1.51 and 1.27; 1.01, 1.59) death among nulliparous mothers. Among preterm infants of parous mothers, intrapartum fever was associated with early neonatal (OR 1.29, 95% CI 1.01, 1.64) death. In the combined analyses (infants of nulliparous and parous mothers), intrapartum fever was a strong predictor of infection-related death. These associations were stronger among term (OR 3.16, 95% CI 1.56, 6.40 for early neonatal; OR 1.75, 95% CI 1.20, 2.57 for infant death) than preterm infants (OR 1.52, 95% CI 1.15, 2.00 for early neonatal; OR 1.29, 95% CI 1.05, 1.57 for infant death). Intrapartum fever was also a risk factor for meconium aspiration syndrome, hyaline membrane disease, neonatal seizures, and assisted ventilation. Conclusion: Intrapartum fever is an important predictor of neonatal morbidity and infection-related mortality.

Ultracooling (to - 196 C) Effects on Barnyard Grass (Echinochloa crusgalli [L.] Beauv.) Secretory Epithelium Ultrastructure and Caryopsis Germination

Barnyard grass (Echinochloa crusgalli [L.] Beauv) florets were ultracooled 0-10 times for 5 min each time to -196 C in liquid nitrogen, thawed for 1 h in air at 24 C, and germinated Germination of caryopsis not ultracooled was 60%, while germination of caryopsis ultracooled 10 times was 99%. Changes occurred in the structure of lipid bodies of the secretory epithelium of unimbibed florets ultracooled either four or 10 times Following water imbibition, lipid bodies regained a similar form as existed prior to ultracooling Protein bodies were digested faster in the secretory epithelium of embryos ultracooled 10 times than in embryos not ultracooled
