The psychometric integrity of a curriculum-based measure to screen for academic giftedness (Monitoring Instructional Responsiveness: Reading [MIR:R]) was evaluated by examining its ceiling, item gradient, and predictive capacity using 460 fourth grade students. Eighty fourth graders (17.39%) scored one standard deviation above the MIR:R mean. Ten fourth graders (2.17%) scored two or more standard deviations above the mean, indicating an adequate ceiling. Item gradients were sufficient, that is, one raw score change produced less than one-third of a standard deviation change in standard deviation units. The MIR:R accurately screened students who performed in the “advanced” range on an end-of-the-year measure (i.e., Tennessee Comprehensive Assessment Program [TCAP]). Results of a chi-square indicated that 78.3% were identified as non-gifted by both the TCAP and MIR:R and 5.9% were identified as gifted.

Abstract This study evaluated the possible effects of sire and dam on age at first calving in Brahman heifers. A total of 570 heifers born between the years 2001 and 2017 were exposed as yearlings to fertile bulls through time of pregnancy determination. A calving code was determined by calculating the mean (993 d) and standard deviation (187 d) of heifer age at first calving. Heifers considered to calve early (≤899 d; calving code = 1) or late (≥1087 d; calving code = 3) were at least half a standard deviation (94 d) away from the mean. All other heifers were considered to have a normal age at first calving (900 to 1086 d; calving code = 2). There were 35 sires with 5 or more daughters, resulting in a total of 543 heifers evaluated for the effect of sire. There were 323 daughters of evaluated heifers, which were evaluated for the effect of dam calving code. Also evaluated was the effect of dam and sire calving code on age at first calving of female offspring (n = 287). Variables analyzed included dam and sire of the heifer, age at first calving, and calving code. Data were analyzed using the GLM procedures of SAS and proportions were tested using Chi-square. Sire calving code did affect (P &lt; 0.01) age at first calving and calving code in heifers, but dam calving code did not affect daughter calving code and age at first calving (Table 1). The proportion of daughters calving early compared to sire calving code significantly differed from the expected proportions (P &lt; 0.01), whereas the proportions of daughters calving early for dam calving code did not differ (Table 2). A selection effort to produce Brahman heifers capable of calving early will not be effective from the dam side, but can be effective on the sire side.

The spontaneous electrical activity was sampled at 2-second intervals from 50 electrodes on the MES area. Chi-square tests indicated normality for the amplitude values of potential obtained at each electrode. The range for standard deviations was 43–113 µv but averaged between 77 and 85 for three animals. Correlation coefficients greater than 0.7 were obtained between electrodes 2 mm apart in the anterior-posterior direction with a decrement to 0.4 at a separation of 4 mm. Dorso-ventrally, correlations greater than 0.7 were obtained between electrodes 4–6 mm apart, suggesting a strip-like character. Low values of correlation were obtained between an electrode in the MES area and an electrode on the AES or PES area. Assuming independence of the true response and spontaneous electrical activity the mean curve and standard deviation curve of the true response were computed. The standard deviation curve of the true response increased during the positive component gradually decreasing toward the end of the negative component.

Knowledge Attitude And Practice

Background: Healthcare professionals are the primary frontiers of the fight against every public health threat. These had made them vulnerable to various infectious agents, with many reports of morbidity and mortality also being evident. Objectives: The current study aimed to assess the knowledge, attitude, and practice toward COVID-19 among community pharmacists in Gondar town, Ethiopia. Methods: A cross-sectional study was conducted. A structured, self-administered questionnaire was used for data collection, and the collected data were coded, validated, and analyzed using SPSS version 26. Quantitative data were summarized using means and standard deviations, while frequencies and proportions were used to summarize categorical data. A chi-square test was used to assess an association between the different variables, and a P-value of less than 0.05 was considered to declare statistical significance at a 95% confidence interval. Results: A total of 46 community pharmacy professionals had participated in the study. The main sources of information about COVID-19 were news media 29 (63%), followed by social media 24 (52.2%). The mean knowledge score was 8.15 (standard deviation: 1.86), and among the total study participants, 29 (63%) were found to have good knowledge about COVID-19. The mean attitude score was 31.52 (standard deviation: 4.288). Only 30.4% of the study participants were found to have a good practice toward the prevention of COVID-19. Chi-square results showed that having a good knowledge of COVID-19 was significantly associated with practice (P = 0.035). Conclusion: Significant gaps were identified concerning community pharmacy professional’s knowledge of COVID-19 and their practice toward prevention of the disease. Strategies should be implemented to equip community pharmacy professionals with all necessary information about COVID-19 through continuous training programs and other virtual platforms.

Background: Diabetes mellitus is a highly prevalent non-communicable disease with a further implication of the development of life-threatening diseases like cardiovascular disease and stroke. Objectives: To determine the glycosylated hemoglobin levels utility in assessing the point of care testing in the control of diabetes mellitus in the population of Nowshera in a hospital-based study. Methods: This was a cross-sectional study, conducted in the department of Pathology in collaboration with the Department of General Medicine, Qazi Hussain Ahmed Medical Complex, Nowshera, from February 2019 to January 2020. Descriptive statistic was used for describing the variables. A Chi-square test was used for the association of Hba1c in gender groups. SPSS version 25 was used for data analysis. Results: Out of the total 119 patients, 44 (37%) were males and 75(63%) were females. The mean age with standard deviation was 53±9.5. The Mean Hba1c with standard deviation was 10.53± 2.38. Sixty-eight (57.1%) of the patients were in the age range 46-60 years. Eighty-eight (73.9%) were poorly controlled diabetics with Hba1c of >9%. Using the chi-square test it was observed that gender has no significant impact on the severity of the disease (p= 0.38). The relative risk of female gender and for age >50years was (RR=1.11). Conclusion: We observed that the majority of the patients had poorly controlled diabetes with Hba1c >9% which is an alarming situation. Age and gender play a very important role in the prognosis of diabetes mellitus.

SummaryThe characteristics of experimental error in measurement of platelet radioactivity have been explored by blind replicate determinations on specimens taken on several days on each of three Walker hounds.Analysis suggests that it is not unreasonable to suppose that error for each sample is normally distributed ; and while there is evidence that the variance is heterogeneous, no systematic relationship has been discovered between the mean and the standard deviation of the determinations on individual samples. Thus, since it would be impracticable for investigators to do replicate determinations as a routine, no improvement over simple unweighted least squares estimation on untransformed data suggests itself.
