Teaching Happiness: The Role Of Positive Psychology In The Classroom, Jennifer M. Gilpin Dec 2008

Teaching Happiness: The Role Of Positive Psychology In The Classroom, Jennifer M. Gilpin

Pell Scholars and Senior Theses

Happiness can be defined in various ways, and characterizing traits that reflect sustained happiness in an individual can be a daunting task. For the purpose of this paper, I propose that contentment regarding the past, satisfaction in the present, optimism about the future, as well as cultivating individual strengths and virtues will result in sustained happiness. Using findings from and relating to the field of positive psychology, I will suggest that these qualities can be fostered in students and will benefit students individually and ultimately society as a whole.

Nondestructive Evaluation Of Aircraft Composites Using Terahertz Time Domain Spectroscopy, Christopher D. Stoik Dec 2008

Nondestructive Evaluation Of Aircraft Composites Using Terahertz Time Domain Spectroscopy, Christopher D. Stoik

Theses and Dissertations

Terahertz (THz) time domain spectroscopy (TDS) was assessed as a nondestructive evaluation technique for aircraft composites. Material properties of glass fiber composite were measured using both transmission and reflection configuration. The interaction of THz with a glass fiber composite was then analyzed, including the effects of scattering, absorption, and the index of refraction, as well as effective medium approximations. THz TDS, in both transmission and reflection configuration, was used to study composite damage, including voids, delaminations, mechanical damage, and heat damage. Measurement of the material properties on samples with localized heat damage showed that burning did not change the refractive …

Dancescape: A Work In Thetranslation Of Bodies And Movement, Julia Allisson Cost Dec 2008

Dancescape: A Work In Thetranslation Of Bodies And Movement, Julia Allisson Cost

Scripps Senior Theses

Translation is inevitably challenging work. When the human body and its movement are the subjects translated, the work may be particularly difficult, as questions both technical and ethical may arise about the representation in the second medium. Yet the exercise can also be very illuminating, creating space for insights that may not have been possible without the translation. For my Scripps College art thesis, I have created a series of paintings of Western dancers and researched four artists whose work involves bodies, movement, or dance and whose approaches differ tremendously. These artists are Edgar Degas (1834-1917), an impressionist painter known …

A Hand Of Steel In A Velvet Glove: Purpose And Fulfillment Through The Gender Sphere, Sylvie A. Shires Dec 2008

A Hand Of Steel In A Velvet Glove: Purpose And Fulfillment Through The Gender Sphere, Sylvie A. Shires

Department of English: Dissertations, Theses, and Student Research

Modern audiences have come to believe that the nineteenth-century woman was oppressed by a patriarchal society and that until women obtained the vote, they had no voice, and could exert no influence to improve either their lot or that of others. While many scholarly secondary sources, as well as popular culture, strongly support this view, this research challenges it, and posits that this generally accepted interpretation echoes stereotypes that became strong with the second wave of feminism, in the 1960s, but is not representative of nineteenth-century middle-class women in the Anglo-Saxon world.

This research examines the British middle-class woman of …

Toward The Development Of An Analysis Methodology For The Elucidation Of Proteome Differentiation Between Two Strains Of Saccharomyces Cerevisiae, Stephanie M. Carter Dec 2008

Toward The Development Of An Analysis Methodology For The Elucidation Of Proteome Differentiation Between Two Strains Of Saccharomyces Cerevisiae, Stephanie M. Carter

Theses

Through continued development, the two-dimensional PAGE gel technique developed by O'Farrell in 1975 has emerged as the hallmark technology utilized in virtually all protein expression analyses. The principle objective of this study was the development and validation of a proteome analysis methodology using this technique suitable for use in determining the quantifiable proteome differences between prion containing [PSI+] and wild type [psi-] strains of Saccharomyces cerevisiae. In addition to the development of an assay, which yields highly reproducible whole proteome isolates from both strains, was the elicitation of statistically significant proteome changes between the two strains. Thus, this study concludes …

Theses and Dissertations

This thesis focuses on the evolution of my work created during my two years of study at Virginia Commonwealth University. Although I touch upon my influences what I am writing is a reflection after the fact that does not necessarily encompass my original intent or inspirations for these works. I find my inspiration from personal discoveries within my daily life. Light flickering through the rails of a fence as I walk by makes me more aware of my body's movement in space. Watching the steady condensation of water droplets forming on a fountain creates a moment of pause within the …

Nymble: Blocking Misbehaving Users In Anonymizing Networks, Patrick P. Tsang, Apu Kapadia, Cory Cornelius, Sean W. Smith Dec 2008

Nymble: Blocking Misbehaving Users In Anonymizing Networks, Patrick P. Tsang, Apu Kapadia, Cory Cornelius, Sean W. Smith

Computer Science Technical Reports

Anonymizing networks such as Tor allow users to access Internet services privately by using a series of routers to hide the client's IP address from the server. The success of such networks, however, has been limited by users employing this anonymity for abusive purposes such as defacing popular websites. Website administrators routinely rely on IP-address blocking for disabling access to misbehaving users, but blocking IP addresses is not practical if the abuser routes through an anonymizing network. As a result, administrators block \emph{all} known exit nodes of anonymizing networks, denying anonymous access to misbehaving and behaving users alike. To address …

Singularities Of Hinge Structures, Ciprian Borcea, Ileana Streinu Dec 2008

Singularities Of Hinge Structures, Ciprian Borcea, Ileana Streinu

Computer Science: Faculty Publications

Motivated by the hinge structure present in protein chains and other molecular conformations, we study the singularities of certain maps associated to body-and-hinge and panel-and-hinge chains. These are sequentially articulated systems where two consecutive rigid pieces are connected by a hinge, that is, a codimension two axis. The singularities, or critical points, correspond to a dimensional drop in the linear span of the axes, regarded as points on a Grassmann variety in its Pl¨ucker embedding. These results are valid in arbitrary dimension. The three dimensional case is also relevant in robotics.

Modeling Of Mixing Time For Bioreactors With Self-Inducing Impellers, Alaa K. M.

Baghdad Science Journal

the mixing time is one of the most useful criterions for characterization of the broths mixing intensity and for scaling up of biosynthesis processes. this parameter value depends mainly on the presence of biomass in the broths, mixing system characteristics and operating conditions. For quantifying the influence of these factors on mixing efficiency, this study was carried out for simulated fermentation aerated broths consisted of carboxymethyl cellulose sodium salt (CMCNa) taking into account the broth's viscosity, rotation speed (rpm) and the stirrer geometry. The experimental results were used in obtaining a correlation to calculate the mixing time for Re <5000, domain of flow regime for which only few data are available from literature. t_m=1.6x10^3xμ^0.43_a/N^1.13X L^0.53 This model offer a good concordance with the experimental results, the average deviation being of 6.6% for CMCNa solutions and can be used for fermentation scaling up.
