"Osteoarthritis is a painful degradation of joint cartilage. Therapies that boost cartilage's limited ability to repair using adipose tissue-derived stem cells (ASCs) have shown promise in cell culture and animal studies, but that success has not carried over to clinical trials. This variability in clinical trials may come down to how the cells are cultured prior to implantation. To test this, a recent study examined a co-culture system combining ASCs taken from the fat pad behind the patella and cartilage cells (chondrocytes). Co-cultured ASCs and chondrocytes had higher expression of cartilage-associated genes than expected, and the effect was larger in cultures with a lower ratio of ASCs to chondrocytes. This gene expression change likely reflects changes in the ASCs and would suggest that the ASCs are starting to make the molecular changes needed to repair damaged cartilage, but increased expression in the chondrocytes, rather than the ASCs, cannot be ruled out without further experiments..."

This course is designed to acquaint students with a variety of approaches to the past used by historians writing in the twentieth century. The books we read have all made significant contributions to their respective sub-fields and have been selected to give as wide a coverage in both field and methodology as possible in one semester’s worth of reading. We examine how historians conceive of their object of study, how they use primary sources as a basis for their accounts, how they structure the narrative and analytic discussion of their topic, and what are the advantages and drawbacks of their various approaches.

This course surveys canonical and recent theories and methods in science studies. We will organize our discussions around the concept of “reproduction,” referring variously to:
Scientific reproduction (how results are replicated in lab, field, disciplinary contexts) Social reproduction (how social knowledge and relations are regenerated over time) Biological reproduction (how organic substance is managed in the genetic age) Electronic reproduction (how information is reassembled in techniques of transcription, simulation, computation).
Examining intersections and disruptions of these genres of reproduction, we seek to map relations among our social, biological, and electronic lives.

Syllabus for Survey of Educational Research Methods course that uses the open textbook Social Science Research: Principles, Methods, and Practices: https://scholarcommons.usf.edu/oa_textbooks/3/
Course description: This course provides students with a survey of methods used in educational research, including qualitative, survey, quantitative group, correlational, single case, and action research. The role of systematic approaches to research in education is considered, and an overview of multiple ways of conducting research in education is provided. Emphasis will be placed on developing students’ competence in locating, evaluating and using published research to inform decision making in educational, clinical, and social settings. Guidelines for evaluating educational research that use the various methodologies are provided. Students will evaluate and critique published research articles.

This graduate seminar introduces an emerging research program within International Relations on territorial conflict. While scholars have recognized that territory has been one of the most frequent issues over which states go to war, territorial conflicts have only recently become the subject of systematic study. This course will examine why territorial conflicts arise in the first place, why some of these conflicts escalate to high levels of violence and why other territorial disputes reach settlement, thereby reducing the likelihood of war. Readings in the course draw upon political geography and history as well as qualitative and quantitative approaches to political science.

"Cancer-related mortality, a leading cause of death in the US, is driven by tumor invasion and metastasis. Implicated in these processes is epithelial-to-mesenchymal transition, or EMT. EMT drives invasion through a dramatic reorganization of a cell's cytoskeleton and the extracellular matrix. Because EMT is a rare event, undergone by a few abnormal cells, it is difficult to view directly in a patient. But new research methods are providing a lens into this critical process. Culturing cells on planar surfaces is revealing how their EMT behavior is coordinated and driven by leader cells. Research on the protein vimentin highlights its role in enabling cells to contort during migration or proliferation. Other studies examine how topographically patterning culture surfaces changes the behaviors of cells as they slip into and out of EMT. And 3D matrices are being used to examine the dissemination and disorganization of multicellular clusters..."

Previously, we showed how different compounds absorb light. The chemical structure of a molecule determines exactly how much light it absorbs, as well as which wavelengths are absorbed. It stands to reason then, that by removing an atom from a molecule, we can change the way it absorbs light. In this experiment, we will relate these two concepts by measuring the absorbance of a molecule under acidic and basic conditions. The changing pH will allow us to find how strongly a specific hydrogen is attached to our molecule, and we will observe how the changing chemical structure affects the observed absorbance. Afterwards, using mathematical analysis, we can experimentally determine the pKa, or affinity of our hydrogen to our parent molecule.
