Making the Grade: Moral Framing and The Catholic Teachers Union of New Jersey
Thesis advisor: Paul GrayOver the past half-century, the percentage of U.S. Catholic secondary school teachers that are laypeople has skyrocketed from approximately 10% in the 1950s to more than 90% in 2006. With this change comes many important issues that beg to be studied in terms of labor relations between these lay employees and the Roman Catholic Church. While the Church has repeatedly made statements in support of labor unions such as in Laborem Exercens, the relations between lay teacher associations and Catholic dioceses in the U.S. have not always mirrored these ideals. This dissertation investigates the case of one organization, the Catholic Teachers Union (CTU), which represents over two-hundred lay teachers at eight high schools in the diocese of Camden, NJ. Using interviews, content analysis, and archival analysis, the investigator found that the union overcame diocesan opposition by deliberately framing (through media outlets and direct communication) their movement and message as strongly connected to Catholic doctrine, Catholic Social Thought, and Church teachings. This "moral framing" helped the union gain support from the parent-consumers sending their children to these schools, which contributed greatly to the union's recognition in 1984 and then their negotiation of nine contracts for diocesan lay teachers. Incorporating Erving Goffman's Frame Analysis, Johnston and Noakes schema for Social Movement Framing, James Coleman and Thomas Hoffer's concept of Social Capital and Intergenerational Closure, and the concept of Community Unionism, the author concludes that CTU can be considered a leader in lay teacher-Catholic Church labor relations and that its tactic of moral framing can inform other unions and the larger labor movement.Thesis (PhD) — Boston College, 2009.Submitted to: Boston College.

Random phase-free kinoform for large objects
We propose a random phase-free kinoform for large objects. When not using the
random phase in kinoform calculation, the reconstructed images from the
kinoform are heavy degraded, like edge-only preserved images. In addition, the
kinoform cannot record an entire object that exceeds the kinoform size because
the object light does not widely spread. In order to avoid this degradation and
to widely spread the object light, the random phase is applied to the kinoform
calculation; however, the reconstructed image is contaminated by speckle noise.
In this paper, we overcome this problem by using our random phase-free method
and error diffusion method
Prostaglandin E2 Synthesizing Enzymes in Rheumatoid Arthritis B Cells and the Effects of B Cell Depleting Therapy on Enzyme Expression
Introduction: B cells may play an important role in promoting immune activation in the rheumatoid synovium and can produce prostaglandin E-2 (PGE(2)) when activated. In its turn, PGE(2) formed by cyclooxygenase (COX) and microsomal prostaglandin E-2 synthase 1 (MPGES1) contributes to the rheumatoid arthritis (RA) pathological process. Therapeutic depletion of B cells results in important improvement in controlling disease activity in rheumatoid patients. Therefore we investigated the expression of PGE(2) pathway enzymes in RA B cells and evaluated the effects of B cell depleting therapy on their expression in RA tissue. Methods: B cells expressing MPGES1 and COX-2 were identified by flow cytometry in in vitro stimulated and control mononuclear cells isolated from synovial fluid and peripheral blood of RA patients. Synovial biopsies were obtained from 24 RA patients before and at two consecutive time points after rituximab therapy. Expression of MPGES1, COX-1 and COX-2, as well as interleukin (IL)-1 beta and IL-6, known inducers of MPGES1, was quantified in immunostained biopsy sections using computerized image analysis. Results: Expression of MPGES1 or COX-2 was significantly upregulated upon stimulation of B cells from blood and synovial fluid while control cells displayed no detectable enzymes. In synovial biopsy sections, the expression of MPGES1, COX-1 or COX-2 was resistant to rituximab therapy at 8 or 16 weeks after start of treatment. Furthermore expression of IL-1 beta in the synovial tissue remained unchanged, while IL-6 tended to decrease after therapy. Conclusions: Therapy with B cell depleting agents, although efficient in achieving good clinical and radiographic response in RA patients, leaves important inflammatory pathways in the rheumatoid synovium essentially unaffecte
Pleiotropic Benefit of Monomeric and Oligomeric Flavanols on Vascular Health - A Randomized Controlled Clinical Pilot Study
BACKGROUND: Cardiovascular diseases are expanding to a major social-economic burden in the Western World and undermine man's deep desire for healthy ageing. Epidemiological studies suggest that flavanol-rich foods (e.g. grapes, wine, chocolate) sustain cardiovascular health. For an evidenced-based application, however, sound clinical data on their efficacy are strongly demanded. METHODS: In a double-blind, randomized, placebo-controlled intervention study we supplemented 28 male smokers with 200 mg per day of monomeric and oligomeric flavanols (MOF) from grape seeds. At baseline, after 4 and 8 weeks we measured macro- and microvascular function and a cluster of systemic biomarkers for major pathological processes occurring in the vasculature: disturbances in lipid metabolism and cellular redox balance, and activation of inflammatory cells and platelets. RESULTS: In the MOF group serum total cholesterol and LDL decreased significantly (P ≤ 0.05) by 5% (n = 11) and 7% (n = 9), respectively in volunteers with elevated baseline levels. Additionally, after 8 weeks the ratio of glutathione to glutathione disulphide in erythrocytes rose from baseline by 22% (n = 15, P<0.05) in MOF supplemented subjects. We also observed that MOF supplementation exerts anti-inflammatory effects in blood towards ex vivo added bacterial endotoxin and significantly reduces expression of inflammatory genes in leukocytes. Conversely, alterations in macro- and microvascular function, platelet aggregation, plasma levels of nitric oxide surrogates, endothelin-1, C-reactive protein, fibrinogen, prostaglandin F2alpha, plasma antioxidant capacity and gene expression levels of antioxidant defense enzymes did not reach statistical significance after 8 weeks MOF supplementation. However, integrating all measured effects into a global, so-called vascular health index revealed a significant improvement of overall vascular health by MOF compared to placebo (P ≤ 0.05). CONCLUSION: Our integrative multi-biomarker approach unveiled the pleiotropic vascular health benefit of an 8 weeks supplementation with 200 mg/d MOF in humans.
