IMPACT: The Journal of the Center for Interdisciplinary Teaching and Learning. Volume 8, Issue 2, Summer 2019
Many of us look for ways to help students forge concrete connections between their academic studies and the real
world. Universities encourage professors to develop community-based learning, allowing students to contribute to the
community beyond their campus in a way that enhances their academic studies and enables them to create these
connections.
Scholars have theorized the many benefits of community-based learning, but professors have many questions about
how to implement community-based learning in practice. What does a successful community-based learning
assignment look like? What are the different ways to assess students’ learning experiences in community-based
learning assignments? How can one build effective partnerships with community organizations?
In these pages, you will find practical advice, theoretical framework, and firsthand accounts of community-engaged
teaching across disciplines. Learn from professors who have designed assignments allowing students to complete
community projects with refugees, prisoners, veterans, elementary school children, science museums, nursing homes,
public libraries, and ESL populations. Students in an Anthropology course, for instance, conduct oral history interviews
with refugees, and provide written transcriptions of the interviews that the refugees can then use as a learning tool in
ESL classes. In a Science Methods class, students collaborate with an aquarium to produce meaningful exhibits that
educate the public. First-year writing students work with veterans to create autobiographical films and write papers

Oral Antimicrobial Peptides and Biological Control of Caries
The presence of antimicrobial peptides (AMPs) in saliva may be a biological factor that contributes to susceptibility or resistance to caries. This manuscript will review AMPs in saliva, consider their antimicrobial and immunomodulatory functions, and evaluate their potential role in the oral cavity for protection of the tooth surface as well as the oral mucosa. These AMPs are made in salivary gland and duct cells and have broad antimicrobial activity. Alpha-defensins and LL37 are also released by neutrophils into the gingival crevicular fluid. Both sources may account for their presence in saliva. A recent study in middle school children aimed to determine a possible correlation between caries prevalence in children and salivary concentrations of the antimicrobial peptides human beta-defensin-3 (hBD-3), the cathelicidin, LL37, and the alpha-defensins. The levels of these AMPs were highly variable in the population. While levels of LL37 and hBD-3 did not correlate with caries experience, the mean alpha-defensin level was significantly higher in children with no caries than in children with caries (p < 0.005). We conclude that several types of AMPs that may have a role in oral health are present in unstimulated saliva. Low salivary levels of alpha-defensin may represent a biological factor that contributes to caries susceptibility. Our observation could lead to new ways to prevent caries and to a new tool for caries risk assessment
The impact of women's social position on fertility in developing countries
This paper examines ideas about possible ways in which the extent of women's autonomy, women's economic dependency, and other aspects of their position vis-à-vis men influence fertility in Third World populations. Women's position or “status” seems likely to be related to the supply of children because of its links with age at marriage. Women's position may also affect the demand for children and the costs of fertility regulation, though some connections suggested in the literature are implausible. The paper ends with suggestions for future research.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45660/1/11206_2005_Article_BF01124382.pd

Mechanisms of leukocyte migration across the blood–retina barrier
Immune-mediated inflammation in the retina is regulated by a combination of anatomical, physiological and immuno-regulatory mechanisms, referred to as the blood–retina barrier (BRB). The BRB is thought to be part of the specialised ocular microenvironment that confers protection or “immune privilege” by deviating or suppressing destructive inflammation. The barrier between the blood circulation and the retina is maintained at two separate anatomical sites. These are the endothelial cells of the inner retinal vasculature and the retinal pigment epithelial cells on Bruch’s membrane between the fenestrated choroidal vessels and the outer retina. The structure and regulation of the tight junctions forming the physical barrier are described. For leukocyte migration across the BRB to occur, changes are needed in both the leukocytes themselves and the cells forming the barrier. We review how the blood–retina barrier is compromised in various inflammatory diseases and discuss the mechanisms controlling leukocyte subset migration into the retina in uveoretinitis in more detail. In particular, we examine the relative roles of selectins and integrins in leukocyte interactions with the vascular endothelium and the pivotal role of chemokines in selective recruitment of leukocyte subsets, triggering adhesion, diapedesis and migration of inflammatory cells into the retinal tissue
