Re-imagining Collectivities: The Mexican Japanese during World War II
Abstract:
The removal from the United States/Mexico borderlands of persons of Japanese descent during World War II resulted in great losses which, until now, have not been acknowledged by the Mexican or the United States government. Although their forced relocation is an event of great significance in the relations of the two countries involved in their displacement, the official narratives deny any deep impact suffered by Japanese Mexicans. However, the question of their uprooting is inextricably linked to the loss of civil rights and the Mexican government’s compliance with the United States’ requirement to neutralize internal enemies. This paper explores the experience of the Japanese Mexican community during World War II through the poetry of Martin Otsuka as well as through my literary intervention in the narrative of the Japanese diaspora. Inspection of the research and creative writing process involved in narrating the Mexican Japanese relocation throws light on the reconfiguration of identities that diasporic communities forge horizontally. My research and perspective as a Chinese Mexican writer allows me to argue that geographical displacement made possible the creation of new identities and solidarities during World War II that superseded, at times, nationalist affiliations
Effect of Quality of Wheat and Maize Flour in Tempura Batter
**This is a metadata-only record**
Due to a technical issue the file(s) associated with this record are no longer available. We apologise for the inconvenience.
Record updated on 26.04.2016 by EMA (TIS).Tempura batters are stand-alone systems that are not further breaded. They provide a protective
coating which can range in texture from crispy/crunchy to cake-like. Recipes for batter systems are
adjusted empirically, and the choice of ingredients, especially flour, will determine the quality and
acceptability of coating. This study aims to characterise wheat and maize flours that would optimise
fried tempura quality, and to study their effect on behaviour of batters, and quality of fried products.
In aqueous ethanol, results showed RVA to be useful to characterise wheat flours for batter
applications. There is a close relationship between flour attributes and flour starch pasting behaviour.
Positive correlation was found between 1st peak viscosity (starch) and 2nd peak viscosity (protein) (r
= 0.768). Farinograph and Extensograph data were correlated to RVA, but of minimum use for flour
batter functionality due to the absence of a gluten network. Maize plays a strong role in batter
viscosity control, and various viscosity measuring methods were applied. Empirical methods were
easy and rapid, but arbitrary, subjective and not precise. Imitative tests were an improvement, but
less precise than rheometry. The BS cup method was more accurate at 50ml than at 70ml, and they
were positively correlated (r2 = 0.99). Back extrusion (BE) data showed a strong correlation with
CFS and BS cups measurement. Using Pearson correlation analyses, positive correlations were
found between viscosity from BS Cup and firmness (r = 0.851), BS cup and consistency (r =
0.891), CFS cup and firmness (r = 0.74), and CFS cup and consistency (r = 0.768). Therefore,
BE is recommended as an alternative to the above. Maize flour pasting properties varied with the
flour particle size. Peak viscosity correlates negatively with particle size (r = -0.959), and positively
with starch damage (r = 0.83). Rheology of different flour combinations in tempura batter was
studied, and links between texture parameters in relation of flour type and concentration were
established, and can be used to guide development/selection of wheat and maize flour for batters.
An electron microscopy low vacuum low temperature SEM method was used successfully to
visualise the microstructure of a range of deep-fried battered chicken samples linked to specific
formulations which established links between structure and function, and eating qualities.
Sensory evaluation of texture discriminated between coatings on chicken pieces, and was consistent
to instrumental analysis, i.e. extended Kraft knife on crust and core while simultaneously measuring
the sound pressure level of the emitted sound. Acoustic parameters extracted from the compression
curves were useful. Positive correlations were found between breading crispness with No. force
peaks and No. sound peaks, i.e. r = 0.749 and r = 0.693 respectively. Moisture and fat contents of
the core and crust were related to the texture, but exceptions were linked to very dissimilar crispness;
which would depend on water distribution within the crust. Ease of breakdown on the mouth
contributes to preferences of texture. More work on the interaction between wheat and maize flours,
and batter rheological, thermal, and textural properties, will further this project’s significant
contribution to the knowledge of the effects of flours selection and formulation on batter technology
and coated product quality.Kerry Ingredient
Testing Single-Parameter Classical Standpoint Cosmology
Experimental tests of homogeneous-universe classical standpoint cosmology are
proposed after presentation of conceptual considerations that encourage this
radical departure from the standard model. Among predictions of the new model
are standpoint age equal to Hubble time, energy-density parameter , and relations between redshift, Hubble-scale distribution of
matter and galaxy luminosity and angular diameter. These latter relations
coincide with those of the standard model for zero deceleration. With eye to
further tests, geodesics of the non-Riemannian standpoint metric are explicitly
given. Although a detailed thermodynamic ``youthful-standpoint'' approximation
remains to be developed (for particle mean free path small on standpoint
scale), standpoint temperature depending only on standpoint age is a natural
concept, paralleling energy density and redshift that perpetuates thermal
spectrum for cosmic background radiation. Prospects for primordial
nucleosynthesis are promising.Comment: 27 pages, latexed, math_macros.tex used, full postscript available

Anticholinergic Medications and Cognition in Older Adults
A significant portion of the cognitive decline seen in older adults may be due to anticholinergic medications (i.e., muscarinic receptor antagonists) which are known to cause memory loss, confusion, and delirium. A competitive radioligand binding assay has been used in the research setting to measure the cumulative level of muscarinic receptor binding present in an individual's serum, referred to as serum anticholinergic activity (AA). Serum AA is the measure of binding of all compounds present in a person's serum (e.g., medications, metabolites, and possibly endogenous substances) to muscarinic receptors. Multiples studies have shown that even low serum AA levels are associated with impaired cognitive performance, impaired self-care capacity, and the presence of delirium in nondemented or mildly demented elderly. Serum AA has the potential to be a useful tool for clinicians. However, there are multiple items which first need to be addressed to enhance the reliability and clinical applicability of this assay. One concern is that the muscarinic receptor binding profiles of most medications and their metabolites have never been examined. Thus, even if a clinician decides that a patient is suffering from anticholinergic-induced toxicity, he/she has little guidance on which medication(s) to adjust. To address this issue, we investigated the in vitro AA of 106 commonly used medications and estimated the relationship between dose and AA in older adults. The change in serum AA over time in the absence of medication adjustments is not known. Another limitation is that serum AA is a peripheral measure, while the central anticholinergic effects of a medication are dependent on its distribution into the CNS. An optimal tool to predict medication-induced cognitive impairment would be one which better estimates drug distribution into the CNS. To address these issues, we conducted a pilot study investigating the utility of using centrally mediated pupillary oscillationsin conjunction with serum AA as a possible predictor of cognitive performance. Serum AA levels and ocular response were measured in a double-blind, cross-over study across an 8 hour time period following administration of placebo or the anticholinergic medication, oxybutynin

Nothing Besides Remains: Preserving the Scientific and Cultural Value of Paleontological Resources in the United States
Receptor occupancy assessed by Positron Emission Tomography (PET) can provide important translational information to help bridge information from one drug to another or from animal to man. The aim of this thesis was to develop nonlinear mixed effects methods for estimation of the relationship between drug exposure and receptor occupancy for the two mGluR5 antagonists AZD9272 and AZD2066 and for the 5HT1B receptor antagonist AZD3783. Also the optimal design for improved estimation of the relationship between drug exposure and receptor occupancy as well as for improved dose finding in neuropathic pain treatment, was investigated. Different modeling approaches were applied. For AZD9272, the radioligand kinetics and receptor occupancy was simultaneously estimated using arterial concentrations as input function and including two brain regions of interest. For AZD2066, a model was developed where brain/plasma partition coefficients from ten different brain regions were included simultaneously as observations. For AZD3783, the simplified reference tissue model was extended to allow different non-specific binding in the reference region and brain regions of interest and the possibility of using white matter as reference was also evaluated. The optimal dose-selection for improved precision of receptor occupancy as well as for improved precision of the minimum effective dose of a neuropathic pain treatment was assessed, using the D-optimal as well as the Ds-optimal criteria. Simultaneous modelling of radioligand and occupancy provided a means to avoid simplifications or approximations and provided the possibility to tests or to relax assumptions. Inclusion of several brain regions of different receptor density simultaneously in the analysis, markedly improved the precision of the affinity parameter. Higher precision was achieved in relevant parameters with designs based on the Ds compared to the D-optimal criterion. The optimal design for improved precision of the relationship between dose and receptor occupancy depended on the number of brain regions and the receptor density of these regions. In conclusion, this thesis presents novel non-linear mixed effects models estimating the relationship between drug exposure and receptor occupancy, providing useful translational information, allowing for a better informed drug-development
