Protective and vulnerability factors for physically abused children: effects of ethnicity and parenting context

OBJECTIVE: Although social maladjustment appears to be common among abused children, negative outcomes are not inevitable. This investigation was designed to determine whether ethnicity and features of the parenting context predicted children's social adjustment, and whether the strength and direction of these relations differed for abused and nonabused children. METHOD: Participants included 78 physically abused and 75 demographically matched nonabused children and one of their parents. Observations of parenting were used to measure parental sensitivity, and parent self-reports of depression were obtained using the SCL-90-R. Children's peer social adjustment was measured by teacher report. RESULTS: Using regression analysis, we tested whether each potential protective or vulnerability factor interacted with abuse status in prediction of social adjustment. Results indicated main effects of ethnicity and sensitivity for prosocial behavior, and a main effect of sensitivity for aggression. In addition, there was a significant interaction of ethnicity and abuse status for aggression such that there was a significant difference between abused and nonabused European American children but not between abused and nonabused African American children. CONCLUSIONS: Findings indicate that risk for aggressive behavior among abused children might be culturally specific rather than universal. In addition, results point to beneficial effects of parental sensitivity for maltreated children.     

The Critical Role of Stereopsis in Virtual and Mixed Reality Learning Environments

Anatomy education has been revolutionized through digital media, resulting in major advances in realism, portability, scalability, and user satisfaction. However, while such approaches may well be more portable, realistic, or satisfying than traditional photographic presentations, it is less clear that they have any superiority in terms of student learning. In this study, it was hypothesized that virtual and mixed reality presentations of pelvic anatomy will have an advantage over two-dimensional (2D) presentations and perform approximately equal to physical models and that this advantage over 2D presentations will be reduced when stereopsis is decreased by covering the non-dominant eye. Groups of 20 undergraduate students learned pelvic anatomy under seven conditions: physical model with and without stereo vision, mixed reality with and without stereo vision, virtual reality with and without stereo vision, and key views on a computer monitor. All were tested with a cadaveric pelvis and a 15-item, short-answer recognition test. Compared to the key views, the physical model had a 70% increase in accuracy in structure identification; the virtual reality a 25% increase, and the mixed reality a non-significant 2.5% change. Blocking stereopsis reduced performance on the physical model by 15%, on virtual reality by 60%, but by only 2.5% on the mixed reality technology. The data show that virtual and mixed reality technologies tested are inferior to physical models and that true stereopsis is critical in learning anatomy.     

Breaking barriers: The landscape of human and veterinary medical anatomy education and the potential for collaboration

Despite human (HUM) and veterinary (VET) medical institutions sharing the goal of educating future clinicians, there is little collaboration between them regarding curricular and pedagogical practices during the preclinical/basic science training years. This may be, at least in part, due to a lack of understanding of each type of curriculum. This study presents data about curricula, student populations, pedagogical methodologies applied, and anatomy educators' training at both HUM and VET institutions. Preclinical curricula, admissions criteria, and student demographics were analyzed for 21 institutions in the United States having both HUM and VET schools. This dataset was augmented by a questionnaire sent to anatomists internationally, detailing anatomy curricula, pedagogies applied, and anatomy educators' training. Many curricular similarities between both training programs were identified, including anatomy education experiences. However, VET programs were found to include more preclinical coursework than HUM programs. Students who matriculate to VET or HUM schools have similar academic records, including prerequisite coursework and grade point average. Median HUM class size was significantly larger, and the percentage of women enrolled in VET institutions was significantly higher. Training of anatomy educators was identical with one exception: VET educators are far more likely to hold a clinical degree. This study elucidates the substantial similarities between VET and HUM programs, particularly in anatomy education, underscoring the potential for collaboration between both types of programs in areas such as interprofessional education, bioethics, zoonotic disease management, and postgraduate training.     

Disability Studies, Cultural Analysis, and the Critical Practice of Technical Communication Pedagogy

This article critically analyzes how technical communication practices both construct and are constructed by normalizing discourses, which can marginalize the experiences, knowledges, and material needs of people with disabilities. In particular, the article explores how disability studies theories can offer critical insights into research in two areas: safety communication and usability. In conclusion, the article offers ways that disability studies can intervene in the pedagogy of usability, communication technology, linguistic bias, narrative, and discourse communities.     

Effects of Supervisor Social Influence,Nonverbal Immediacy,and Biological Sex on Subordinates' Perceptions of Job Satisfaction,Liking, and Supervisor Credibility

This study investigated the impact of supervisor biological sex, power use, and nonverbal immediacy on subordinates' satisfaction, liking for the supervisor, and perceptions of the supervisors' credibility. After viewing video scenarios of male and female supervisors engaging in nonverbally immediate (or nonimmediate) and prosocial (or antisocial) power use, subordinates reported perceptions of satisfaction, affect, and credibility. Results of the 2 × 2 × 2 experimental design indicated significant main effects for supervisor prosocial power and nonverbal immediacy. Although there were interaction effects, the variance accounted for was minimal. Supervisor prosocial power use and nonverbal immediacy were positively and significantly related to subordinates' self-reported satisfaction, liking for the supervisor, and work enjoyment. Supervisor biological sex did not show a relationship to any of the criterion variables. This study demonstrates that supervisors should maintain nonverbal immediacy and frame prosocial-type messages to preserve their credibility in the workplace.     

Replacing Old Spatial Empires of the Mind

In this article we argue for the spatialization of research on educational transfer in the field of comparative education within a theoretical framework that focuses on networks, connections, and flows. We present what we call a "spatial empire of the mind," which is comprised of a set of taken-for-granted "truths" about space and place that have legitimized much research in the social sciences. We critique this spatial empire of the mind and present some of the core ideas associated with the spatial turn. The next part of the article reviews three possible ways that new spatial theorizing has been taken up in educational research. Here we make reference to existing educational studies that engage with new ways of rethinking space and place. The argument that we put forward is that the most promising approach, for research on educational transfer within the field of comparative education, is network spatiality. We argue that there is great value in rethinking space and place not simply as objects of study, but within a theoretical framework that focuses on networks, interconnections, and movements within and between them, as well as their productive capacity to produce and shape knowledge, identities, and human subjectivities.     

Structural Models for Binary Repeated Measures: Linking Modern Longitudinal Structural Equation Models to Conventional Categorical Data Analysis for Matched Pairs

The current widespread availability of software packages with estimation features for testing structural equation models with binary indicators makes it possible to investigate many hypotheses about differences in proportions over time that are typically only tested with conventional categorical data analyses for matched pairs or repeated measures, such as McNemar’s chi-square. The connection between these conventional tests and simple longitudinal structural equation models is described. The equivalence of several conventional analyses and structural equation models reveals some foundational concepts underlying common longitudinal modeling strategies and brings to light a number of possible modeling extensions that will allow investigators to pursue more complex research questions involving multiple repeated proportion contrasts, mixed between-subjects × within-subjects interactions, and comparisons of estimated membership proportions using latent class factors with multiple indicators. Several models are illustrated, and the implications for using structural equation models for comparing binary repeated measures or matched pairs are discussed.     

Productive Uncertainty: The Pedagogical Benefits of Co‐Creating Research in the Design Studio

Balancing the competing demands of research and teaching has long been lamented by academics. The challenges associated with Covid‐19 will make this increasingly difficult. An integrated approach to research and teaching, where students are directly engaged in the production of research, may provide a useful strategy to support ongoing research within the design disciplines whilst befitting student learning. The production of original research requires a willingness to engage in – and manage –uncertainty. Contemporary higher education acknowledges that global challenges are increasing in complexity and, thus, students require opportunities to learn to productively manage this complexity. Utilising teacher observations and student feedback, this article reflects critically on a studio model, iteratively refined over two semesters, with the deliberate intent of exacerbating the complexity already present within studio pedagogy for the production of new knowledge. It outlines a set of strategies for making manageable this uncertainty for students to ensure it is beneficial for their learning. It also identifies a number of challenges educators can face when assuming a duel role as teacher and research partner; and provides advice for negotiating these challenges.     

Money, sex, and drugs: a case study to teach the genetics of antibiotic resistance

The goal of the work reported here was to help students expand their understanding of antibiotic resistance, the Central Dogma, and evolution. We developed a unit entitled "Ciprofloxacin Resistance in Neisseria gonorrhoeae," which was constructed according to the principles of scientific teaching by a team of graduate students, science faculty, and instructors. A variety of activities and assessments were used, including a case study, short lectures, and group problem-solving. Implementation of "Ciprofloxacin Resistance in Neisseria gonorrhoeae" in a college freshman seminar suggests these materials are useful in increasing understanding of complex biological topics and improving problem-solving abilities.
