Heights, weights, and head circumferences were obtained on 1,006 students, ages 5 to 18 years, attending regular classes in four schools in a suburban Seattle school district. From the 1,006 students initially examined, 19 (1.9%) had a head circumference two or more standard deviations below the mean for age and sex. Intelligence quotients and academic achievement scores were obtained on these children and compared with normal controls. No significant difference was found between mean IQs of the study subjects and the controls (99.5 vs. 105), but mean academic achievement scores were significantly lower in the study subjects (49 vs. 70; P < .001). In addition, although mean IQs were not significantly different between those subjects whose head circumference was proportional and those whose head circumference was relatively small, mean academic achievement scores were significantly higher (60 vs. 39; P < .02) in those subjects whose head size was proportional.

The problem of the study. The conventional assessment methods used in evaluating the academic achievement of students have been saddled with deficiencies. Research methods. This study examined the effect of assessment for learning method on students’ academic achievement in carpentry and joinery works in technical colleges in Edo and Delta States, Nigeria using quasi-experimental research design. The population for this study comprised of 430 students and the sample size was 68 vocational II carpentry and joinery students from two intact classes randomly drawn from the 12 technical colleges in Edo and Delta States. The instrument used for data collection was Carpentry and Joinery Works Achievement Test (CJWAT) developed by the researcher from NBTE curriculum. The instrument was tested by three experts. The reliability of CJWAT was calculated using Kuder Richardson formulae 21 (KR-21) and a reliability coefficient of .78 was achieved. Mean and standard deviation were used to address study questions whereas one-way and two-way Covariance Analysis (ANCOVA) were used to evaluate hypotheses at a .05 level of significance. Results. The study's findings revealed that the learning method assessment (9.43) had a higher achievement score than the traditional method of assessment (5.25), indicating that the learning method assessment had a greater impact on student achievement in carpentry and carpentry than the traditional method of assessment. One-way ANCOVA result, F(1,77) = 56.75, p = .000 indicates a significant difference between the two assessment methods with regards to students’ achievement in carpentry and joinery trade. Female students (9.34) find the Assessment for Learning Method to be marginally more effective than male students (9.30). On the other hand, the Two-way ANCOVA result, F(1,75) = 1.83, p = .180 shows no significant difference between the academic achievement scores in carpentry and joinery trade of the students’ based on gender. It is therefore concluded that there is a significant difference between the mean achievement scores of students assessed with Assessment for Learning method and those assesses with the conventional assessment method in favour of assessment for learning method and no significant difference between the mean achievement scores of male and female students assessed with assessment for learning method at post-test. Conclusion. It was proposed, among other items, that the government and all stakeholders organize and fund seminars, conferences and workshops for technical teachers on a regular basis to attend and learn how to adopt assessment for learning method in educational institutions through the application of rubrics and portfolios.

The purpose of this study was to re-affirm our clinical impression that non-institutionalized children whose head circumference was below minus 2 standard deviations were mentally subnormal and frequently had growth failure. A group of 134 children with a head circumference below minus 2 standard deviations from the mean were studied, and all but one were mentally subnormal. The most severe mental retardation was noted in the group of children with a head circumference of minus 4 standard deviations or below. We found, as have others, that children with mental retardation have height and weights below the expected norm and that children with a head circumference below minus 2 standard deviations have even lower mean heights and weights. The head circumference of 31 children with growth failure and normal intelligence was normal for age and sex, therefore disproving the concept that the abnormally small child has a proportionally small head. In the child with growth failure, should the head be proportionally small (below minus 2 standard deviations), mental subnormality should be suspected. We feel that the head circumference measurement has taken on new clinical significance in that our data support its use in suspecting the association of mental subnormality in children with growth failure and a head circumference of below minus 2 standard deviations from the mean for age and sex.

<p><em>Background</em>. This ecological study examines the relationship between food desert prevalence and academic achievement at the school district level. <br /><em>Design and methods.</em> Sample included 232 suburban and urban school districts in New York State. Multiple open-source databases were merged to obtain: 4th grade science, English and math scores, school district demographic composition (NYS Report Card), regional socioeconomic indicators (American Community Survey), school district quality (US Common Core of Data), and food desert data (USDA Food Desert Atlas). Multiple regression models assessed the percentage of variation in achievement scores explained by food desert variables, after controlling for additional predictors.<br /><em>Results</em>. The proportion of individuals living in food deserts significantly explained 4th grade achievement scores, after accounting for additional predictors. School districts with higher proportions of individuals living in food desert regions demonstrated lower 4th grade achievement across science, English and math. <em><br />Conclusions</em>. Food deserts appear to be related to academic achievement at the school district level among urban and suburban regions. Further research is needed to better understand how food access is associated with academic achievement at the individual level.</p>

This study examines the extent to which the type of instruction used during a general chemistry laboratory course affects students’ ability to use core ideas to engage in science practices. We use Ford’s (2008) description of the nature of scientific practices to categorize what student do in the laboratory as either empirical or representational. One approach to lab instruction, engages students in the empirical practices of science but in a traditional prescriptive manner designed to demonstrate and verify content. The second approach, Argument-Driven Inquiry (ADI), engages students in both the empirical and representational practices of science. A practical exam was used to compare student learning in each condition. The assessment targeted student ability to participate in specific scientific practices, including planning and conducting investigations, analyzing and interpreting data and arguing from evidence. Students who were taught with either ADI (N= 81) or Traditional (N= 76) had equivalent understanding of content based on the ACS-GCST exam, however the mean score on the practical exam was significantly higher for students in the ADI sections. Results also indicate that the mean scores on the practical exam were significantly higher in the ADI sections for all students including female students, under-represented minority (URM) students, and students with lower past academic achievement. In the traditional laboratory sections there was a significant difference in the mean scores on the practical exam for the URM student relative to the majority, which was not present in the ADI sections. However, the opposite was found for students with low past academic achievement; the mean score on the practical exam was significantly lower for the students in the ADI sections in comparison to the traditional sections.

Introduction: Early prediction of the outcome in patients with cardiopulmonary arrest (CPA) is important to select the optimal management. The pupil diameter is a simple neurological examination and it predicts the prognosis in patient with stroke. However, the clinical significance of pupil diameter in CPA has not been elucidated. Hypothesis: We hypothesized that pupil diameter would predict the prognosis of CPA patients. Methods: We retrospectively analyzed consecutive 45 patients with CPA and return of spontaneous circulation (ROSC) after cardiopulmonary resuscitation in our hospital. We analyzed age, sex, cause of CPA, time during CPA, pupil diameter at admission and death in hospital. Results: The mean of age was 67±20 years and male were 34 (76%). The median of CPA time was 33 min [25%, 75%; 22, 46] and pupil diameter was 4.8 mm [3.0, 6.0]. The 26 (58%) patients died in hospital after ROSC. There was no significant difference in age and sex between survival (n=19) and dead (n=26). The CPA time was significantly shorter in survival than that in dead (21 min [10, 39] vs 30 min [30, 52], p=0.005). Furthermore, pupil diameter was significantly smaller in survival compared with dead (3.0mm [2.5, 4.3] vs 5.0mm [4.4, 6.0]) (Figure). The receiver-operating characteristic (ROC) curve for survival after ROSC demonstrated that the area under curve was 0.73 and provided an optimal cut-off value at 4.0mm in pupil diameter with 75% sensitivity and 75% specificity. When CPA time was 28 minutes, the area under curve was 0.76, and sensitivity and specificity were 78% and 71%, respectively. Conclusion: As same as CPA time, pupil diameter is suggested to predict the outcome after ROSC in CPA patients.

Abstract. The clinical picture and serum antithyroid antibodies in 16 pairs of siblings with Graves' disease were compared with an age and sex matched group of 32 patients with Graves' disease who did not have a family history of any thyroid disease (control patients). There was a significant difference in frequency and mean titres of antibodies to thyroglobulin between sibling patients. (positive 76.0%) and control patients (positive 40.0%), but not in microsomal antibodies (sibling; positive 92.0%, control; 92.0%). There were no significant differences in the mean values of 24 h 131I-thyroidal uptake, serum T3U, serum T4 and T3 concentrations before treatment between the two groups. Lymphoid follicles and degeneration of the epithelia were more often found in the thyroid glands of sibling patients than in those of the control patients, when 32 (16 sibling, 16 control) thyroid glands from the same groups in the clinical study, including antibody series, were examined pathologically after subtotal thyroidectomy for Graves' disease. Moreover, there was a strong tendency to increased lymphocyte and plasma cell infiltration in the thyroid glands of sibling patients with Graves' disease. The findings might indicate that Graves' disease is closely related to Hashimoto's thyroiditis, especially in sibling patients with Graves' disease.

The responses of cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) to administration of acetazolamide were investigated in 16 patients with dementia and ventriculomegaly to clarify the cerebral hemodynamics in patients with idiopathic normal-pressure hydrocephalus (NPH). The mean CBF velocity in the whole brain was measured by the Patlak plot method by using technetium-99m hexamethylpropyleneamine oxime single-photon emission computerized tomography. The CVR values were obtained from the response to administration of 500 mg of acetazolamide and calculated as the percentage of change from the baseline mean CBF value. The mean CBF value was significantly reduced (p < 0.01) in six patients with (35.2 ± 5 ml/100 g/minute) and 10 patients without (33.5 ± 2.8 ml/100 g/minute) NPH compared with the age-matched normal controls (40.8 ± 3.2 ml/100 g/minute), showing no significant difference. The CVR was significantly impaired in patients with NPH (0.8 ± 1.7%; p < 0.001), whereas in patients without NPH preserved CVR (11.3 ± 3%) was demonstrated compared with the normal controls (14.7 ± 1.1%). In patients with NPH a significantly lower CVR (p < 0.001) was shown than in those without NPH. The CVR significantly increased (p < 0.001) after placement of a shunt in patients with NPH. Reductions in both CBF and CVR may be diagnostic indicators of NPH in patients with dementia in whom ventriculomegaly is present. In patients with dementia and idiopathic NPH both reduced CBF and extremely impaired CVR are shown. The results of the present study suggest that ischemia due to the process of NPH is responsible for the reduction of CBF and manifestation of symptoms in patients with idiopathic NPH.
