Making Space for Place: Mapping Tools and Practices to Teach for Spatial Justice

This article presents a set of spatial tools for classroom learning about spatial justice. As part of a larger team, we designed a curriculum that engaged 10 learners with 3 spatial tools: (a) an oversized floor map, (b) interactive geographic information systems (GIS) maps, and (c) participatory mapping. We analyze how these tools supported learning using notions of politicization. The floor map fed conceptual understandings of the map as a representational text and served as the terrain for an embodied activity to support proportional reasoning about inequitable distributions of resources. The data-rich GIS maps and their zoomability allowed for coordinating across multiple variables to connect patterns in inequities to other social processes. The participatory mapping enabled learners to make discoveries about, connect, and share beyond the individual classroom counterstories from people in the lived streets of their neighborhood. In aggregate, this set of spatial tools produced a complex, hybrid view of the city’s space, which contributed to learners’ political formation.     

Superoxide dismutase and catalase activities and their correlation with malondialdehyde in schizophrenic patients

Free radical mediated pathological processes may have a role in schizophrenia. Free radicals (oxy radicals, such as superoxide, hydroxyl ions and nitric oxide) cause cell injury, when they are generated in excess or when the antioxidant defense is impaired. Both these processes seem to be affected in schizophrenia. In this study we investigated erythrocyte superoxide dismutase (SOD) and catalase (CAT) activities as antioxidant enzymes, malondialdehyde (MDA) as a sign of lipid peroxidation in schizophrenic patients. Activities of superoxide dismutase, catalase and malondialdehyde were greater in patients compared with the control group which may reflect increased oxidative stress in the brain tissue of schizophrenics. In the patient group erythrocyte SOD and CAT activities were weakly negative correlated with MDA concentration. These data reveal that antioxidant defense mechanisms might be impaired in schizophrenic patients. These findings also provide a theoretical basis for the development of novel therapeutic strategies, such as antioxidant supplementation.     

Age related changes in lipid peroxidation and antioxidants in elderly people

Advanced age is associated with an accumulation of free radical damage, which leads to physiological and clinical modifications. Age related changes resulting from free radical reactions include increasing levels of lipid peroxides, alterations in enzyme activities and greater osmotic fragility. The present study was conducted to estimate the level of lipid peroxidation product-Malondialdehyde and antioxidants Catalase and Glutathione in elderly people. An increase in lipid peroxidation and decrease in antioxidants was observed in normal elderly people. Highly significant increase in MDA and decrease in antioxidants was observed in elderly people when complicated with diabetes and hypertension. Supplementation of antioxidants may prevent further oxidative injury in elderly people.

Identifying Factors that Influence the Successful Transition of Criminal Justice Transfer Students

Higher educational institutions place a priority on the retention and timely graduation of students. Previous literature has identified transfer students to have unique concerns and that these concerns vary by major. While previous retention research has reported factors that influence students’ decision to remain in college, many of these studies treated transfer status as a homogenous group. The university in this study enrolls a high percentage of transfer students, and a large percentage of these transfers students enroll in Criminal Justice classes and become Criminal Justice majors. To determine if there are unique risk factors among Criminal Justice transfer students, this study uses multiple measures of transfer status to identify factors that might impact a students’ (1) university involvement, (2) GPA, (3) satisfaction with and sense of belonging to their university and (4) thereby influence their decision to remain in school. The proposition that transfer students as compared to native (nontransfer) students differ on how they face university challenges was also examined. While several variables were found to be important to students’ adjustment to the University, transfer status does not appear to be significant risk factor. Implications of the results are discussed.     

Evaluating the Graduation Gap: Interventions Designed to Enhance Upper-level Student Success and Commitment

Over the past several decades, there has been a wealth of research identifying factors and conditions of persistence toward graduation for first-year students and more recently transfer students. While previous research recognizes these critical periods, some recent literature suggests that students may face a similar transitional period later in their academic careers as they advance into their major areas of study. To date, there has been a dearth of information exploring upper-level students' success and commitment to graduation. Exploring this later transition might provide a critical link to understanding the graduation gap between those students who persist to graduation and those who drop out. The purpose of this research was to review the intervention programs proscribed by the literature, design an intervention program, and examine the impact of the program on criminal justice students during this advanced transitional phase of their college careers. It examined the direct and indirect effects of the intervention program on both retention and the antecedents of successful retention while controlling for other relevant influences identified in the literature. The results indicated that the intervention had small, but significant positive direct and indirect effects on academic integration, commitment to the university, and graduating in a timely fashion. Policy implications are discussed.     

WOMEN PRESIDENTS DEFINE THE COLLEGE CULTURE THROUGH STORY

The concept of the leader's need to leave a record so that others know that she was present at a community college at a given point in time, working on behalf of the communities she served, is the theme of this article, which consists of stories from the lives of seven current and former community college chief executive officers, Vivian B. Blevins, Pamila Fisher, Sylvia Ramos, Carol Tatsey-Murray, Jerry Sue Thornton, Carolyn G. Williams, and Parker Williams give accounts of how they came to their positions as chief executive officers, the challenges and joys of that work, and the legacies they hope to leave. Their accounts as academic laborers are important tools for exploring the meaning of their roles and the roles of those they serve, for educating the uninitiated in the mission of the community college, and for reinforcing the value of that mission to the lives of community college students past, present, and future.     

Empirical Performance of Covariates in Education Observational Studies

This article summarizes results from 12 empirical evaluations of observational methods in education contexts. We look at the performance of three common covariate-types in observational studies where the outcome is a standardized reading or math test. They are: pretest measures, local geographic matching, and rich covariate sets with a strong theory of treatment selection. Overall, the review demonstrates that although the pretest often reduces bias in observational studies, it does not always eliminate it. Its performance depends on the pretest's correlation with treatment selection and the outcome, and whether preintervention trends are present. We also find that although local comparisons are prioritized for matching, its performance depends on whether comparable no-treatment cases are available. Otherwise, local comparisons may produce badly biased results. In cases where researchers have a strong theory of selection and rich covariate sets, observational methods perform well, but additional replication studies are needed. Finally, observational methods that rely on demographic covariates without a theory of selection rarely produce unbiased treatment effects. The article concludes by offering education researchers empirically based guidance on covariate selection in observational studies.
