CAVEman: Standardized anatomical context for biomedical data mapping

The authors have created a software system called the CAVEman, for the visual integration and exploration of heterogeneous anatomical and biomedical data. The CAVEman can be applied for both education and research tasks. The main component of the system is a three‐dimensional digital atlas of the adult male human anatomy, structured according to the nomenclature of Terminologia Anatomica. The underlying data‐indexing mechanism uses standard ontologies to map a range of biomedical data types onto the atlas. The CAVEman system is now used to visualize genetic processes in the context of the human anatomy and to facilitate visual exploration of the data. Through the use of Java? software, the atlas‐based system is portable to virtually any computer environment, including personal computers and workstations. Existing Java tools for biomedical data analysis have been incorporated into the system. The affordability of virtual‐reality installations has increased dramatically over the last several years. This creates new opportunities for educational scenarios that model important processes in a patient's body, including gene expression patterns, metabolic activity, the effects of interventions such as drug treatments, and eventually surgical simulations.

How has Mexican faculty been trained? A national perspective and a case study

This article depicts how faculty members at Mexican higher education institutions have been prepared in order to assume their professional responsibilities. It relies on three elements: First, a secondary analysis of a national faculty survey composed of 3,861 faculty members from 65 institutions; second, 34 interviews conducted in eight higher education institutions; third, a primary analysis of an institution faculty survey in a public autonomous university. Results are presented regarding the following issues: first, the central traits of anticipatory or formative in-site faculty socialization; second, the changes in the highest degree faculty obtained at entry into academic life as compared to the obtained degree at the time of the survey; third, the formative time patterns during faculty’s higher education training, fourth, the conditions of study under which faculty members obtained their graduate degrees; and fifth, the academic inbreeding phenomenon.     

A Cross-Cultural Analysis of Early Prelinguistic Gesture Development and Its Relationship to Language Development

Many Western industrialized nations have high levels of ethnic diversity but to date there are very few studies which investigate prelinguistic and early language development in infants from ethnic minority backgrounds. This study tracked the development of infant communicative gestures from 10 to 12 months (n = 59) in three culturally distinct groups in the United Kingdom and measured their relationship, along with maternal utterance frequency and responsiveness, to vocabulary development at 12 and 18 months. No significant differences were found in infant gesture development and maternal responsiveness across the groups, but relationships were identified between gesture, maternal responsiveness, and vocabulary development.

The Meyerhoff Way: How the Meyerhoff Scholarship Program Helps Black Students Succeed in the Sciences

The Meyerhoff Scholarship Program (MSP) is widely recognized for its comprehensive approach of integrating students into the science community. The supports provided by the program aim to develop students, primarily Blacks, into scientists by offering them academic, social, and professional opportunities to achieve their academic and career goals. The current study allowed for a rich understanding of the perceptions of current Meyerhoff students and Meyerhoff alumni about how the program works. Three groups of MSP students were included in the study: (1) new Meyerhoff students participating in Summer Bridge (n = 45), (2) currently enrolled Meyerhoff students (n = 92), and (3) graduates of the MSP who were currently enrolled in STEM graduate studies or had completed an advanced STEM degree (n = 19). Students described the importance of several key aspects of the MSP: financial support, the Summer Bridge Program, formation of Meyerhoff identity, belonging to the Meyerhoff family, and developing networks—all of which serve to integrate students both academically and socially.     

Change management in extremis: A case study

After 40 years under one manager, the Circulation Department at the Richard J. Daley Library was long past due for a change. The challenge of reorganizing included interesting and interrelated aspects: changes to workflows and assignments, moving staff and functions inside the department and across departments, and a deep dive into the culture to which staff had become habituated. Managers eliminated redundancies and increased services, effectiveness, productivity, and joy. This case study is a testament to how successful change happens with patience, respect, and a willingness to be flexible.

Effects of Population Heterogeneity on Accuracy of DIF Detection

Heterogeneity within English language learners (ELLs) groups has been documented. Previous research on differential item functioning (DIF) analyses suggests that accurate DIF detection rates are reduced greatly when groups are heterogeneous. In this simulation study, we investigated the effects of heterogeneity within linguistic (ELL) groups on the accuracy of DIF detection. Heterogeneity within such groups may occur for a myriad of reasons including differential lengths of time residing in English-speaking countries, degrees of exposure to English-speaking environments, and amounts of English instruction. Our findings revealed that at high levels of within-group heterogeneity, DIF detection is at the level of chance, implying that a large proportion of DIF items might remain undetected when assessing heterogeneous populations potentially leading to developing biased tests. Based on our findings, we urge test development organizations to consider heterogeneity within ELL and other heterogeneous focus groups in their routine DIF analyses.
