The Slide: Image and Object
Through an extensive review of the literature of the history and methodology of art history and visual resources, this thesis charts the effect of the use of slides for the discipline of art history.
The three chapters examine the conjunction between slides and art history. Chapter one gives an account of the pedagogical and practical reasons for the current predominance of the slide as the reproduction of choice in art history, concluding with a discussion of the relative importance of the text and image for art history. The second chapter briefly traces the evolution of magic lantern to 35mm format for slides and projectors. Consideration will be given to the slide as an object itself, including those aspects which are unique to the slide, as well as qualities it shares with photography in general. The final chapter considers the question of the nature of the relationship between the reproduction and original. After a discussion of the variety of words used in place of reproduction, I will note how the most appropriate choices for art history are those terms which imply replacement.
This study concludes that the use of the slide has created a paradox in art history. Use of the photographic reproduction may be seen to heighten the awareness of the original, especially when the user or viewer is aware of the slide as an object with peculiar properties itself, and not just as a neutral tool or visual referent. Yet, by loosening the absolute hold of the original as the sole appropriate subject of study, art history has become a highly theoretical discipline, with a literary tradition, rather than restricting itself to critical commentary on objects and their creators
Comprehensive investigation of Ge-Si bonded interfaces using oxygen radical activation
In this work, we investigate the directly bonded germanium-silicon interfaces to facilitate the development of high quality germanium silicon hetero integration at the wafer scale. X-ray photoelectron spectroscopy data is presented which provides the chemical composition of the germanium surfaces as a function of the hydrophilic bonding reaction at the interface. The bonding process induced long range deformation is detected by synchrotron x-ray topography. The hetero-interface is characterized by measuring forward and reverse current, and by high resolution transmission electron microscopy. (C) 2011 American Institute of Physics.

Permissive human cytomegalovirus infection of a first trimester extravillous cytotrophoblast cell line
Human cytomegalovirus (HCMV) is the leading cause of congenital viral infection in the United States and Europe. Despite the significant morbidity associated with prenatal HCMV infection, little is known about how the virus infects the fetus during pregnancy. To date, primary human cytotrophoblasts (CTBs) have been utilized to study placental HCMV infection and replication; however, the minimal mitotic potential of these cells restricts experimentation to a few days, which may be problematic for mechanistic studies of the slow-replicating virus. The aim of this study was to determine whether the human first trimester CTB cell line SGHPL-4 was permissive for HCMV infection and therefore could overcome such limitations. HCMV immediate early (IE) protein expression was detected as early as 3 hours post-infection in SGHPL-4 cells and progressively increased as a function of time. HCMV growth assays revealed the presence of infectious virus in both cell lysates and culture supernatants, indicating that viral replication and the release of progeny virus occurred. Compared to human fibroblasts, viral replication was delayed in CTBs, consistent with previous studies reporting delayed viral kinetics in HCMV-infected primary CTBs. These results indicate that SGHPL-4 cells are fully permissive for the complete HCMV replicative cycle. Our findings suggest that these cells may serve as useful tools for future mechanistic studies of HCMV pathogenesis during early pregnancy

Investigating the Comprehensive Inventory of Thriving (CIT) as a rehabilitation outcome measure
Reliable and valid outcome measures are needed in community rehabilitation settings following acquired neurological injury. The Comprehensive Inventory of Thriving (CIT) (Su, Tay and Diener, 2013) was investigated for this purpose. The CIT is a 54 item self-report measure that provides 18 subscales and seven main scales of thriving: Relationships, Engagement, Mastery, Autonomy, Meaning, Optimism and Subjective Well-being. Participants (n=76) were administered the CIT on admission to a community rehabilitation service. The mean age of participants was 54.8 (SD = 17.7), with 43% being male. The main diagnostic groups were cerebrovascular disease (28%), traumatic brain injury (17%) and Parkinson's disease (12%). Internal consistency was moderate to high (α =.6 to .9) for all subscales with the exception of Support (Relationships) and Skills (Mastery); and high (α=.79-.93) for all indexes with the exception of Subjective Wellbeing. Correlational analyses supported the scale groupings. However, the subscales of Support (Relationships) and Skills (Mastery) did not correlate significantly with any subscales. Additionally the Subjective Well-being scale should not be calculated, but instead its three subscales (Negative Feelings, Life Satisfaction, Positive Feelings) used individually. In terms of demographic variables, there were no significant gender differences on CIT scales. Age had low correlations with two Relationships subscales only (Trust r=.23, p=.04; Loneliness r=-.25, p=.03). Diagnostic group minimally influenced CIT scores. Significant between-group differences were only found for Accomplishment (Mastery), with post-hoc analyses indicating higher levels for the cerebrovascular group. The CIT shows considerable promise in rehabilitation outcomes as a reliable and valid multi-component measure of wellbeing
Maine’s State Parks: Their Value to Visitors and Contribution to the State Economy
Maine’s state parks are important to the social and economic well-being of the state, and provide public access to a variety of outdoor activities. In the study reported here, the authors find that visitors have a high level of satisfaction in Maine’s day-use parks, campgrounds and historic sites. Moreover, the overall impact of visitor-related park spending exceeds $30 million in income and 1,449 jobs annually. Nonetheless, the majority of Maine’s state parks suffer from long-deferred maintenance and are in immediate need of major capital improvements if they are to continue their vital role in supporting tourism and outdoor recreation
Peptide inhibition of human cytomegalovirus infection
<p>Abstract</p> <p>Background</p> <p>Human cytomegalovirus (HCMV) is the most prevalent congenital viral infection in the United States and Europe causing significant morbidity and mortality to both mother and child. HCMV is also an opportunistic pathogen in immunocompromised individuals, including human immunodeficiency virus (HIV)- infected patients with AIDS, and solid organ and allogeneic stem cell transplantation recipients. Current treatments for HCMV-associated diseases are insufficient due to the emergence of drug-induced resistance and cytotoxicity, necessitating novel approaches to limit HCMV infection. The aim of this study was to develop therapeutic peptides targeting glycoprotein B (gB), a major glycoprotein of HCMV that is highly conserved across the <it>Herpesviridae </it>family, that specifically inhibit fusion of the viral envelope with the host cell membrane preventing HCMV entry and infection.</p> <p>Results</p> <p>Using the Wimley-White Interfacial Hydrophobicity Scale (WWIHS), several regions within gB were identified that display a high potential to interact with lipid bilayers of cell membranes and hydrophobic surfaces within proteins. The ability of synthetic peptides analogous to WWIHS-positive sequences of HCMV gB to inhibit viral infectivity was evaluated. Human foreskin fibroblasts (HFF) were infected with the Towne-GFP strain of HCMV (0.5 MOI), preincubated with peptides at a range of concentrations (78 nm to 100 μM), and GFP-positive cells were visualized 48 hours post-infection by fluorescence microscopy and analyzed quantitatively by flow cytometry. Peptides that inhibited HCMV infection demonstrated different inhibitory concentration curves indicating that each peptide possesses distinct biophysical properties. Peptide 174-200 showed 80% inhibition of viral infection at a concentration of 100 μM, and 51% and 62% inhibition at concentrations of 5 μM and 2.5 μM, respectively. Peptide 233-263 inhibited infection by 97% and 92% at concentrations of 100 μM and 50 μM, respectively, and 60% at a concentration of 2.5 μM. While peptides 264-291 and 297-315, individually failed to inhibit viral infection, when combined, they showed 67% inhibition of HCMV infection at a concentration of 0.125 μM each.</p> <p>Conclusions</p> <p>Peptides designed to target putative fusogenic domains of gB provide a basis for the development of novel therapeutics that prevent HCMV infection.</p
Get Cookin’: Investigating the Effects of a Six-week Cooking Intervention on Cooking and Dietary Behaviors among Low-income Families
Background and Purpose: Healthy eating practices have been associated with prevention of chronic diseases. There is limited information about strategies for healthy eating practices among families. The current study examined the effectiveness of Get Cookin’, a six-week intervention consisting of nutrition education and hands-on cooking and tasting activities among low-income families. Methods: Lowincome adults participated in Get Cookin’, a six-week intervention consisting of nutrition education and hands-on cooking activities. Ninety-six participants completed a retrospective survey which examined their meal planning, budgeting and cooking behaviors, as well as fruit and vegetable consumption. Thirteen graduates of the program participated in focus groups. The Wilcoxon signed ranks test was used to examine pre-to-post changes. Results: Participants showed significant improvements in meal planning and budgeting skills. They started cooking meals at home more frequently and increased consumption and variety of healthy foods such as fruits, vegetables and whole grains. Focus groups revealed that participants shared cooking and nutrition information and skills learned with their families. Additionally, participants with diverse backgrounds gained a sense of empowerment to overcome personal challenges to make healthy choices. Conclusions: Nutrition education, combined with cooking and tasting activities, appears to have a positive impact on healthy behaviors among low-income families. Further research with a control group would be needed to more definitively understand the effectiveness of the Get Cookin’ intervention
