Instrumental and sensory characteristics of selected nutritionally improved school foods
No full textChildhood obesity is a growing problem in the United States. Recently enacted Federal and State regulations require school foods to be improved nutritionally. The objective of this study was to determine quality of selected newly developed school foods using instrumental and sensory methods. From the National School Lunch Program reimbursable meals chicken nuggets, macaroni and cheese, and pierogies were selected. From the Competitive Foods apple snacks were used. Surface color parameters (L, a*, and b*) were determined by colorimeter and digital camera. A texture analyzer (TA-xT2i) was used to measure texture specific to each product. Sensory Quantitative Descriptive analysis was used to evaluate six to eight sensory attributes per product. The results were compared with similar traditional products. Chicken nuggets with whole grain breading were darker red (L 132.43 and a* 147.96) and coarser, while home style were more yellow (b* 188.44) with firmer breading (407.59 g) and original variety was less yellow and red (b* 182.69 and a* 138.01) with softer meat texture (462.26 g/cm). Macaroni and cheese with 26% reduced fat was significantly saltier and less viscous than original (1486.21 g), however not significantly different in color, cheese aroma, or sweetness. Pierogies with 70% more protein per serving were significantly different with a firmer, grainier filling and darker surface color with values of L 59.14 and b* 14.98 and peak force of filling 7968.9 g. Freeze dried enriched apple snacks were significantly lighter in color, more red (L 170.13 and a* 137.71), firmer texture with average 2821.24 g peak force, more sour, bitter and had a rougher surface texture than air-dried apple snacks. Instrumental color, texture, and sensory characteristics of nutritionally improved products differed significantly from the similar traditional products. Additional efforts of processors will be necessary to prepare nutritionally improved products with high children's acceptability.M.S.Includes bibliographical references (p. 94-104)by Alyson Mandevill

Using non-contact AFM to study the local doping and damping through the transition in an ultrathin VO2 film
No full textBulk VO2 undergoes an insulator-to-metal transition (IMT) with up to five order of magnitude change its resistivity at 340 K. However, when VO2 is deposited as a film on a substrate, the strain from the substrate can alter the IMT temperature, resistivity ratio, and hysteresis. Here, we present single-phase VO2 ultrathin films (thick- ness less than 20 nm) grown using oxygen plasma molecular beam epitaxy (MBE) on TiO2(001) and Al2O3(0001) substrates. First, we modify existing recipes employing ozone MBE and reproduce the best reported films on TiO2(001); maintaining an almost three order of magnitude transition in a 12 nm thick film. We then extend our recipe to Al2O3(0001) substrates where we stabilize a 12 nm thin single-phase VO2 film and observe a two order of magnitude transition, expanding the possible growth methods for ultrathin VO2 films on Al2O3(0001).
In a separate, approximately 10 nm thick VO2 film on TiO2(001), we use non-contact AFM (nc-AFM) to track electronic properties across the expected temperature range of transition. We first observe a change in the work function of VO2 at the expected bulk transition temperature. We then measure the frequency shift and dissipation at varying bias and tip-sample separation at seven stable temperatures, spanning the insulating to the metallic state. Using the frequency shift data, we ex- tract the tip-sample capacitance, then calculate the induced carrier doping within the sample as a result of the proximity of the tip. The work function, carrier density, and damping results above and below the IMT suggest that we observe the IMT; with the damping in particular showing consistent behavior with a decrease in resistance starting as low at 270 K and continuing to 300 K. Furthermore, we observe a change in work function at fixed temperature at close tip-sample separation as low as 240 K, along with elevated damping, suggesting the electric field from the tip itself may be initiating the transition, at least in the surface of the film, at temperatures as low as 240 K in the close tip-sample separation regime
The importance of Joule heating on the voltage-triggered insulator-to-metal transition in VO₂
No full textThe large change in resistivity in the material VO₂ has attracted considerable attention since it was first discovered in 1959. Recently, the ability to trigger the insulator-to-metal transition (IMT) with a strong electric field has been observed, but there has been debate about whether the transition is due to field-effects. We apply a voltage bias across a VO₂ thin film via a conductive atomic force microscope (CAFM) tip and measure the resultant current. We observe the IMT as a jump in the measured current in the IV curves. We fit the IV curves to the Poole-Frenkel (PF) conduction mechanism in the insulating state, immediately preceding the IMT. The PF conduction mechanism describes the thermal excitation of electrons into the conduction band in insulators, facilitated by strong electric fields. The PF mechanism is temperature dependent, and we use the temperature dependence to calculate the local temperature of the film before the transition. We directly compare the local electric field and local temperature of the film immediately preceding the IMT. We determine that the transition is not solely due to the applied electric field, but rather that the tip has locally warmed the film close to its IMT temperature through Joule heating.Science, Faculty ofPhysics and Astronomy, Department ofGraduat

A Thesis in Seasons
No full textA personal take on a thesis. Alyson Davies uses narratives of her rural Albertan upbringing to position her art practice and experience in Emily Carr University’s MFA program. Davies painting, primarily based in autobiographical narratives, is also met by supplementary practices across other media where seasonality and nature direct the subject of the works. The thesis paper aims to contextualize Davies’ artworks along other artist’s work, and within the physical and inner worlds the work exists in.SeasonalityPrairiesFarmingFarmBetty WoodmanVanessa BellMary FeddenAnita Klei
On necrocapitalism: A plague journal
No full textM.I. Asma is the collective designation for six authors from Canada and the United States, representing a variety of revolutionary anticapitalist theoretical persuasions: J. Moufawad-Paul, Devin Zane Shaw, Mateo Andante, Johannah May Black, Alyson Escalante, and D. W. Fairlane. As the pandemic transitioned from science fiction to reality in early 2020, a number of writers and thinkers in the imperialist metropoles declared the impossibility of writing in the face of a future that is foreclosed. And yet, due to the nightmare that capitalism has been since its beginning, numerous writers and thinkers from the margins have always written in the face of such foreclosure. Meanwhile, other contemporary thinkers sought to conceptualize the unfolding pandemic according to conceptions of bio/necropolitics, forgetting the foundation upon which these conceptions have always existed.
The M.I. Asma writing group came together to stake out a different terrain, thinking through the pandemic as events unfolded while also always working to think beyond the capitalist imaginary. Writing between April 2020 and May 2021, the authors set out to produce a serial theoretical philosophical project focused on class struggle in the midst of the COVID-19 pandemic. The authors approached the pandemic as an occasion to think capitalism according to what it always has been, what the pandemic reveals about its current ideological deployment, and how we can think about a communist alternative in the face of exterminism.
This book collects, with some revisions and with a new epilogue, the entries from the On Necrocapitalism blog, where M.I. Asma’s interventions first appeared.DC Author's celebration 202
Utilizing content analysis on TheKnot.com to study an online wedding planning community for New Jersey
No full textAs with other aspects of our culture today, wedding planning is increasingly discussed and implemented online. Information is disseminated through online media attention, advertising, and computer mediated communication. The latter provides an avenue through which the impact of community building and relational culture can be established. My dissertation analyzes an online wedding planning forum on TheKnot.com to exemplify the ways by which a community is built through online postings and discusses the characteristics of this community. Utilizing the uses and gratification theory, content gratifications are examined through the types of topics publically viewable on an active online wedding planning Website. Because of the extensive reach of such forums, one particular region, New Jersey, will be examined. Process gratifications will be discussed as participants share personal experiences from their time spent on this particular online bulletin board planning their wedding celebration. Furthermore, the dynamics of interaction among this group will be analyzed over the course of half a calendar year and will show the types of interaction taking place through content analysis.Ph.D.Includes bibliographical referencesby Alyson H.

Experiencing Kane: an 'affective approach' to Sarah Kane's experiential theatre in performance
No full textDeposited with permission of the author. © 2008 Dr. Alyson Evette CampbellThe thesis investigates the theatre of British playwright Sarah Kane, focusing particularly on her last work, 4.48 Psychosis. This play about suicide, written by a playwright who then committed suicide, has been widely, and understandably, read as a suicide note that can have little political relevance or engagement with wider society. The thesis responds to this interpretation and argues for a re-evaluation of Kane’s last work. It contends that alternative, more political, readings of the play are possible and proposes that close attention to Kane’s term ‘experiential’ theatre is one way to produce such a reading.
The thesis, therefore, undertakes an investigation into experiential theatre, and does this through a dual practical and theoretical methodology. I approach the research as a theatre practitioner – a director – and as a scholar, with the result that the thesis is undertaken and organised as 50% written dissertation and 50% creative work. In the dissertation I theorize ‘experiential theatre’: what it is; how it works dramaturgically; and how this dramaturgy can be read as politically significant. I adopt a predominantly phenomenological approach to argue that Kane’s experiential theatre is concerned primarily with the embodied nature of spectatorship and the visceral affect of live performance, and that this is the site of its potential political efficacy. The creative work, my direction of a production of 4.48 Psychosis for Red Stitch Actors Theatre (July-August 2007), investigates the viability of this new critical framework in practice.
Out of this combined practical and theoretical investigation the thesis concludes that, given an appropriate critical paradigm, it is possible to read 4.48 Psychosis as experiential theatre, and to theorise experiential theatre as underpinning the political engagement of Kane’s dramaturgy. However, in practice, the work is only ever potentially experiential, being contingent upon the decisions made by the creative team, the unpredictable outcome of those decisions upon the individual spectator and the material circumstances of the production itself
