The performance of White students and Hispanic students from California, Texas, and Arizona on the advanced placement (AP) biology exam was compared using archival data from the College Board from 2016 through 2019. Pearson Chi-square tests yielded statistically significant differences in all 4 year comparisons of white and Hispanic students in all three states. White students from California had the highest percentage of students earn a 3 or higher for all 4 years, Arizona had the second highest percentage of white students earn a 3 or higher for all 4 years, and Texas had the lowest percentage of white students earn a 3 or higher for all 4 years of comparison. Hispanic students from Arizona had the highest percentage of students earn a 3 or higher for all 4 years, California had the second highest percentage of Hispanic students earn a 3 or higher for all 4 years, and Texas had the lowest percentage of Hispanic students earn a 3 or higher for all 4 years of comparison. It was discovered a majority of White students who took an AP biology exam, from 2016 to 2019, earned a passing score (3 or higher), while the majority of Hispanic students who took an AP Biology exam failed to earn a passing score (3 or higher), that would result in college credit. Implications of these findings are discussed. [ABSTRACT FROM AUTHOR]

The New Caledonian crow (Corvus moneduloides) is known for displaying a unique set of tool-related behaviours, with the bird's bill acting as an individually consistently lateralized effector. However, we still fail to understand how such laterality develops, is modulated or even if its expression is consistent across other behavioural categories. Creating the first ethogram for this species allowed us to examine laterality and vocalisations in a population of wild, free-flying New Caledonian crows using detailed analyses of close-up video footage. We revealed the existence of an overall strong left-sided bias during object manipulation only and which was driven by the adult crows of our focal population, the stabilization of individual preferences occurring during the birds' juvenile years. Individually, at least one crow showed consistent side biases to the right and left within different behavioural categories. Our findings highlight previously unknown variability in behavioural laterality in this species, thus advocating for further investigation. Specifically, we argue that a better understanding of the New Caledonian crow's biology and ecology is required if one wishes to pursue the promising comparative road that laterality could be connected to the evolution of tool-making.

Background: To report the complexity and richness of study variables within biological nursing research, authors often use tables; however, the ease with which consumers understand, synthesize, evaluate, and build upon findings depends partly upon table design. Objectives: To assess and compare table characteristics within research and review articles published in Biological Research for Nursing and Nursing Research. Method: A total of 10 elements in tables from 48 biobehavioral or biological research or review articles were analyzed. To test six hypotheses, a two-level hierarchical linear model was used for each of the continuous table elements, and a two-level hierarchical generalized linear model was used for each of the categorical table elements. Additionally, the inclusion of probability values in statistical tables was examined. Results: The mean number of tables per article was 3. Tables in research articles were more likely to contain quantitative content, while tables in review articles were more likely to contain both quantitative and qualitative content. Tables in research articles had a greater number of rows, columns, and column-heading levels than tables in review articles. More than one half of statistical tables in research articles had a separate probability column or had probability values within the table, whereas approximately one fourth had probability notes. Conclusions: Authors and journal editorial staff may be generating tables that better depict biobehavioral content than those identified in specific style guidelines. However, authors and journal editorial staff may want to consider table design in terms of audience, including alternative visual displays. [ABSTRACT FROM AUTHOR]
