Source: Laboratories of Nicholaus Noles and Judith Danovitch—University of Louisville Infants are born with amazing cognitive resources at their disposal, but they don’t know how to use them effectively. In order to harness the power of their brains, humans must develop high-level cognitive processes that manage basic brain functions. These processes make up what psychologists refer to as executive function. Executive function is a key factor in many self-regulatory behaviors, including forming...

A method for isolating specific cell types from plant material is demonstrated. This technique employs transgenic marker lines expressing fluorescent proteins in particular cell types, cellular dissociation and Fluorescence Activated Cell Sorting. Additionally, a growth setup is established here that facilitates treatment of Arabidopsis thaliana seedlings prior to cell sorting.

We describe a sorting strategy for mouse spermatids using flow cytometry. Spermatids are sorted into four highly pure populations, including round (spermiogenesis steps 1-9), early elongating (spermiogenesis steps 10-12), late elongating (spermiogenesis steps 13-14) and elongated spermatids (spermiogenesis steps 15-16). DNA staining, size and granulosity are used as selection parameters.

FAQs
Preserving record-level associations is essential because an observation usually contains several related values. When records are ordered by one variable, the corresponding values in other variables must move with them. Otherwise, the dataset no longer represents the original observations, and later inspection of relationships, rankings, or statistical summaries may be based on mismatched information.
Ascending and descending numerical order place low or high observations at the most visible ends, while alphabetical, date-based, or ranked-score ordering organizes nonnumeric information differently. The selected rule should match the variable being examined. Choosing an appropriate order makes extremes, repeated categories, chronological patterns, or rank positions easier to inspect.
Once values are ordered, unusually large gaps, unexpected repetitions, or implausible positions become easier to notice. Comparing the sequence with expected values or categories can draw attention to possible entry errors and potential outliers. Sorting therefore supports an initial quality check before researchers proceed to more formal statistical analysis.
A median depends on the ordered position of observations, so sorting places values in the sequence needed to identify the central location. The same ordered sequence allows researchers to assign ranks consistently and organize repeated values for frequency tables. These results can then support statistical summaries and visualizations within the dataset.
First identify the variable or variables that determine the order. Next choose the rule, such as ascending, descending, alphabetical, date, or ranked-score order. Apply it to complete records rather than isolated cells, then inspect the resulting sequence for extremes, gaps, repetitions, and possible errors before calculating summaries or creating visualizations.
An ordered dataset gives researchers a clearer basis for grouping repeated observations into frequency tables and for viewing how values are distributed across a sequence. It can also make minimums, maximums, gaps, trends, and potential outliers easier to recognize. As a preparation step, sorting improves organization before results are displayed or analyzed.
