In search for molecules displaying ferromagnetic exchange: multiple-decker Ni12 and Ni16 complexes from the use of pyridine-2-amidoxime

The use of pyridine-2-amidoxime (pyaoxH2) in Ni chemistry has provided access to a dodecanuclear complex and a hexadecanuclear Ni cluster, namely [Ni12(pyaox)6(pyaoxH)6(MeOH)2Cl2]Cl4·5MeOH (1·5MeOH) and [Ni16(pyaox)8(pyaoxH)8(MeOH)4](SO4)4·10H2O·26MeOH (2·10H2O·26MeOH). Complex 1·5MeOH was isolated by the reaction of NiCl2·6H2O, pyaoxH2 and NaOMe in a 1 : 1 : 2 molar ratio in MeOH in 60% yield. Treatment of NiSO4·6H2O with pyaoxH2 and NEt3 in a 1 : 1 : 2 molar ratio in MeOH afforded 2·10H2O·26MeOH in good yield (65%). The two compounds display a multi-decker configuration based on stacked Ni4 layers, {Ni4(pyaox)2(pyaoxH)2}2+x (x = 3, 1·5MeOH; x = 4, 2·10H2O·26MeOH); each deck consists of two square planar and two octahedral NiII centres. The number of decks observed in 1·5MeOH and 2·10H2O·26MeOH depends on the nature of the inorganic anion that is present in the reaction system, which provides elements of synthetic control towards new high nuclearity NiII species. 2·10H2O·26MeOH is the first structurally characterized complex of any metal displaying a quadruple-decker configuration, being also the highest nuclearity metal cluster bearing pyaoxH2 and the highest nuclearity NiII cluster with any type of 2-pyridyl oxime. Each cluster cation displays ferromagnetic exchange between the octahedral NiII ions resulting in a spin ground state of S = 6 for 1 and S = 8 for 2. Magnetothermal studies have been performed and discussed for both clusters.CP and CE thank the School of Chemistry, NUI Galway, for the financial support.

LetsTalkShots: personalized vaccine risk communication

IntroductionVaccine hesitancy is a global health threat undermining control of many vaccine-preventable diseases. Patient-level education has largely been ineffective in reducing vaccine concerns and increasing vaccine uptake. We built and evaluated a personalized vaccine risk communication website called LetsTalkShots in English, Spanish and French (Canadian) for vaccines across the lifespan. LetsTalkShots tailors lived experiences, credible sources and informational animations to disseminate the right message from the right messenger to the right person, applying a broad range of behavioral theories.MethodsWe used mixed-methods research to test our animation and some aspects of credible sources and personal narratives. We conducted 67 discussion groups (n = 325 persons), stratified by race/ethnicity (African American, Hispanic, and White people) and population (e.g., parents, pregnant women, adolescents, younger adults, and older adults). Using a large Ipsos survey among English-speaking respondents (n = 2,272), we tested animations aligned with vaccine concerns and specific to population (e.g., parents of children, parents of adolescents, younger adults, older adults).ResultsDiscussion groups provided robust feedback specific to each animation as well as areas for improvements across animations. Most respondents indicated that the information presented was interesting (85.5%), clear (96.0%), helpful (87.0%), and trustworthy (82.2%).DiscussionTailored vaccine risk communication can assist decision makers as they consider vaccination for themselves, their families, and their communities. LetsTalkShots presents a model for personalized communication in other areas of medicine and public health

Beautiful little dead things: empathy, witnessing, trauma and animals' suffering

© 2014 Dr. Lynn MowsonThis sculptural practice-led research investigates empathy, trauma and witnessing and the role of testimony in visual arts practice. The thesis argues that Edith Stein’s phenomenological account of empathy articulates an empathic encounter that recognizes the alterity of the other. Stein’s account, I argue, can be drawn out to include encounters with nonhuman animals and sculptural objects that resemble embodied forms. Responding to developments in my sculptural practice the research examined the possibility of visual art practices to bear witness to the ongoing suffering of animals: marking out the possibility for sculptural objects to perform as testimonial objects. As testimonial objects they attest to the trauma of the one who witnesses for the other. Ethical considerations in relation to materiality, representation and the position of one who testifies for, or on behalf of, the other are examined

Being Within Sound: Immanence and Listening

This paper aims to provide an overview of composer Angelo Badalamenti’s (b. 1937) contribution in the creation of the dark and dystopian nightmares in the films of David Lynch (b. 1946). The pair have had a unique working relationship since their first film together (Blue Velvet, 1986, USA) and have consequently gone on to work on six films together, a live performance piece, a ground-breaking television series as well as several music albums for singer Julee Cruise (b. 1956). Through his use of dark sound textures and moody orchestration, Badalamenti complements the theme of what can be construed as dread in the familiar that is prevalent in the films of Lynch. The following is an overview of the dark heart of the Lynch/Badalamenti partnership

Reproductive Health Seeking Behaviors Among Female University Students: An Action Oriented Exploratory Study

The focus of this research was to: 1) study the perceptions of female students attending the university Student Health Center, concerning available services, 2) learn how they describe their decisions to obtain care, and 3) identify perceived barriers to reproductive health care and contraception. This exploratory study used a mixed-methods approach that included clinic public-space observations, interviews with health care providers and staff at Student Health Services (SHS), surveys distributed to clients of the campus clinic, and in-depth interviews to contextualize emergent themes. Topics addressed included sexual health behaviors and perceptions, influence of peers and partners, the propagation of health myths, and past experiences with SHS. Gathering practitioner perspectives on student barriers to care, goals of the clinic, and perceived health needs of the student community, allowed for measurement of incongruence between student and staff, thereby adding greater context to results. SHS sought recommendations in order to improve student\u27s use of the Sexual Health and Gynecology clinic, increase accuracy of student\u27s sexual health knowledge, and guide future clinic operations. SHS is now working with the College of Public Health to create improvement projects based on my results, including a peer education program. Research such as this can result in greater student awareness of available services, and more productive communication between patients and provide. Implications on the larger issues of gender and the search for health care, acceptance and knowledge of STI testing, and client comfort are addressed, and provide opportunity for future work in this area

The Journey of the Fool

Design in the civic realm demands opportunities to recognize commonality. Architecture, therefore, must provide a call and response between visitor and space. This intimate dialogue can only occur where landscape elements speak a universal language. Revelatory, Allegorical, Cosmological and Vernacular methods of design have traditionally been employed to communicate in the landscape. This project explores the method of Archetypal design as a means to avoid the culturally-dependent, and hence, esoteric language of design and so create an exoteric language more appropriate for civic space.Master of Landscape Architectur

Patrick Geddes: Synthetic Vision

Among the founders of the science of town planning at the beginning of the twentieth century, Scotsman Patrick Geddes introduced methods of investigation commensurate with other sciences. A biologist, trained by Thomas Huxley, Geddes borrowed the practices of the microscopical laboratory in creating the Outlook Tower in Edinburgh, Scotland which served as a model for an approach to the study of cities. His method was like that of a field botanist studying a species, and assumed an interdependent relationship between place, work and folk. Embracing the evolutionary theory of Charles Darwin, Geddes proposed subtle town planning interventions as a means by which cities could adaptively respond to change over time. He advocated the employ of a graphic device, which he called his "thinking machines," and which served as a paradigmatic strategy to forge new relationships within sets of ideas. Such an approach aligned him with the taxonomic strategies in practice in the formation of museum collections and display of the nineteenth century. This work examines the archival evidence of the principles underlying Geddes' methods in the hope that they may be recovered in contemporary town planning.Ph. D
