Nothing But Change and Variance:
Authors: Scanlon Larry 
Published: April 2014

Abstract
With historicism on the wane, now is a good time to reexamine Thomas Hoccleve's politics. The resurgence of interest in Hoccleve coincided with the advent of critical historicism in Middle English scholarship. Debate on Hoccleve has been sharply divided between those who see him as a royalist and those who see him as politically unaligned. Analysis of Hoccleve's persona in the Regiment of Princes—the most poetically prominent feature of his most important political poem—and its relation to the figure of Fortune demonstrates that, if anything, ideological readings of Hoccleve have underplayed his royalism.
The New York Sound: Citybilly Recording Artists and the Creation of Hillbilly Music, 1924–1932
Authors: Huber Patrick 
Published: April 2014

Abstract
Since at least the 1960s, scholars have viewed hillbilly music as essentially a commercialized form of the traditional rural white folk music of the American South. In reconsidering what has come to be known as the "southern thesis," this article chronicles the significant but often overlooked contributions made by professional New York City studio singers and musicians to the nascent hillbilly recording industry between 1924 and 1932, particularly the principal role they played in the creation of what I call the "New York Sound." These urban artists’ participation in this segment of the recording industry suggests that hillbilly music can best be understood not as an organic folk music of the American South, but rather as a carefully constructed commercial genre that was part of the broader expansion of a nationwide industry of mass-mediated music in the 1920s.
That’s Not Me I See on TV . . . : African American Youth Interpret Media Images of Black Females
Authors: Adams-Bass Valerie N. , Bentley-Edwards Keisha L. , Stevenson Howard C. 
Published: April 2014

Abstract
How do African American youth perceive images of black women in popular media? How do they interpret the meaning of these messages, especially those that maintain persistent negative stereotypes? Focus groups with African American high school and college-age youth were conducted. Findings indicate that youth, both male and female, readily identified many images of black women as negative, inaccurate, and offensive. Further, their responses suggest their concern about the impact of these images on how majority groups may perceive black women and black communities, overall.
An Institutional Case Study: Emotion Regulation with HeartMath at Santa Cruz County Children's Mental Health
Authors: Lutz Barbara 
Published: April 2014

This case study from Santa Cruz County Children's Mental Health Agency (CMH), California, reviews the use of measurement of heart rate variability (HRV) to enhance emotional regulation of patients. CMH serves seriously emotionally disturbed youths, many of whom have been separated from their parents for a prolonged period or have been vulnerable without the consistent presence of their caregivers. In this study, the HRV pattern was calculated as high coherence, medium coherence, or low coherence. According to Thurber et al, heart rhythm coherence “is experienced as a calm, balanced, yet energized and responsive state that is conducive to everyday functioning and interaction, including the performance of tasks requiring mental acuity, focus, problem solving and decision making, as well as physical activity and coordination.”1(p39) In the HeartMath program, there was a game in which high coherence was rewarded with a rainbow that dropped coins into a vessel. When coherence was low, the rainbow and coins disappeared until coherence was reached again. We measured HRV using a finger or ear sensor in individual sessions using a computer-based program from HeartMath Institute, Boulder Creek, California. After juvenile offenders overcame their initial fear of being hooked up to a potential lie detector, I instructed them in “Quick Coherence”1 and asked them to imagine breathing into the area of their heart. The participants created a library of positive feelings, thoughts, and memories on which they could focus. After a period of positive focus and rhythmic breathing, the clients were often able to move into medium or high coherence. In this state, they noticed that they felt calmer. I explained that they could use this tool to improve their mood. I also practiced alongside the youths in order to demonstrate the technique. The detained youths learned quickly, requested repeated sessions, and learned to combine breathing with recalling the good people, places, foods, and feelings in their lives that sustained them. We could also decrease coherence through the use of negative words such as “loss of privileges” on their side or “pay cut” on mine and then move back to coherence with suggestions of positive mental images.
Antifungal Activity of Tamarind (TamarindusindicaLinn.) Leaf Extract Against Colletotrichum gloeosporioides
Authors: David Jonnalexer B. , Gatan Mary Grace B. 
Published: April 2014

Anthracnose (Colletotrichum gloeosporioides) is considered as most important and destructive disease of mango. Use of natural plants is recommended because it is cost-effective and safe. Plant extracts like tamarind shown to have antifungal activity. The experiment was conducted in Pampanga, Philippines following two factor-factorial Complete Randomized Design to determine the antifungal effect of tamarind against anthracnose, specifically to: determine zones of inhibition in C. gloeosporioides as affected by different solvents in young and mature leaf extracts; determine interaction effect between different solvents and type of leaf used; determine the most effective tamarind extract against C. gloeosporioides. Results reveals that young tamarind leaf extract at 1:1 ratio significantly affected the production of zone of inhibition of C. gloeosporioides while the mature tamarind leaf extract did not inhibit the test organism. The ethanol extract using young leaves were the most effective against the test organisms. Findings showed that the use of young tamarind leaf extract using different solvents at 1:2 ratio produced strong effect against anthracnose in terms of inhibitory activity. The use of young leaf ethanol extract against anthracnose was effective and can be considered as good biofungicide because its efficacy is comparable to Mancozeb.

Published: April 2014

AbstractThe aim of this work is to clarify the complex interactions and various influencing parameters regarding the material behavior of deep‐frozen bulk solids. Additionally, a better evaluation of the material behavior in practical applications needs to be ensured. As material samples, hard coal, iron ore, and sand were selected, and cube‐shaped samples saturated with water were deep‐frozen for defined periods of time. Subsequently, the influences of the residence time in the freezer and of the particle size on the material behavior were analyzed by carrying out uniaxial compression tests.
Yoctowell Cavities on Magnetic Silica Nanoparticles for pH Stimuli‐Responsive Controlled Release of Drug Molecules
Authors: Bhosale Sheshanath V. 
Published: April 2014

AbstractDrug‐delivery systems that medically transport active molecules to diseased cells, in a controlled manner, have gained much attention in recent years. Yoctowell (1 yL=8 nm3 that is, 10−24 L volume) cavities on magnetic silica nanoparticles were used for the encapsulation and release of the drug molecule, “mitoxantrone (MTZ)”, and controlled using naturally occurring stimuli, that is, pH. First, MTZ was encapsulated from a bulk solution under physiological conditions, and then released from the yoctowells, in a controlled manner, by manipulating the pH (7.2–3.0). The sustained release of MTZ, the recovery of active yoctowells after the release process and magnetic properties of nanoparticles provide potential for development of a new generation of drug‐delivery system.
