Transforming Energy Usage: It’s Not Only about Solar  [PDF]
Melissa Matlock
Open Journal of Energy Efficiency (OJEE) , 2014, DOI: 10.4236/ojee.2014.32004
Abstract:

GRID Alternatives, a non-profit solar contractor, installs solar electric systems for low-income families. Part of GRID Alternatives’ program is to provide solar electric systems that are designed to replace 75% of the homeowners’ electricity usage with solar power. This leaves 25% of their bill still to be paid. In order to save our resources, one must first use conservation practices, then energy efficiency, and then follow-up with renewable energy to cover the rest. GRID Alternatives Inland Empire (GRID IE) educates our participating homeowners and community members on this philosophy. However, measuring whether or not our families have been following this philosophy is hard to prove. It may seem obvious that if we want to know whether our homeowners are saving energy, we should look at their energy usage before and after solar. However, this is not the case with our low-income families that could be using electricity to make their lives more comfortable. GRID IE developed a survey to be given before homeowners received their solar systems and started their participation with GRID Alternatives and the same survey to be given after they have received their solar systems. This before and after survey (pre-test/post-test) asked our homeowners to rate their responses to 7 questions on a scale of 1 - 10. The before and after responses for each person were compared, and as a group, their differences were calculated to find out if the differences were statistically significance (within subjects, dependent Z test). 6 out of 7 questions showed statistical significance. The big picture is that change is happening among our low-income homeowners and has happened for many of the varied energy saving methods discussed. It is important to transform energy usage, because the solution is not just solved with solar.

Butterfly Tachyons in Vacuum String Field Theory
Peter Matlock
Physics , 2002, DOI: 10.1103/PhysRevD.67.086002
Abstract: We use geometrical conformal field theory methods to investigate tachyon fluctuations about the butterfly projector state in Vacuum String Field Theory. We find that the on-shell condition for the tachyon field is equivalent to the requirement that the quadratic term in the string-field action vanish on shell. This further motivates the interpretation of the butterfly state as a D-brane. We begin a calculation of the tension of the butterfly, and conjecture that this will match the case of the sliver and further strengthen this interpretation.
Extended Josephson Relation and Abrikosov lattice deformation
Peter Matlock
Physics , 2011, DOI: 10.1016/j.physc.2012.02.016
Abstract: From the point of view of time-dependent Ginzburg Landau (TDGL) theory, a Josephson-like relation is derived for an Abrikosov vortex lattice accelerated and deformed by applied fields. Beginning with a review of the Josephson Relation derived from the two ingredients of a lattice-kinematics assumption in TDGL theory and gauge invariance, we extend the construction to accommodate a time-dependent applied magnetic field, a floating-kernel formulation of normal current, and finally lattice deformation due to the electric field and inertial effects of vortex-lattice motion. The resulting Josephson-like relation, which we call an Extended Josephson Relation, applies to a much wider set of experimental conditions than the original Josephson Relation, and is explicitly compatible with the considerations of TDGL theory.
The AdS/CFT Correspondence for the Massive Rarita-Schwinger Field
P. Matlock,K. S. Viswanathan
Physics , 1999, DOI: 10.1103/PhysRevD.61.026002
Abstract: The complete solution to the massive Rarita-Schwinger field equation in anti-de Sitter space is constructed, and used in the AdS/CFT correspondence to calculate the correlators for the boundary conformal field theory. It is found that when no condition is imposed on the field solution, there appear two different boundary conformal field operators, one coupling to a Rarita-Schwinger field and the other to a Dirac field. These two operators are seen to have different scaling dimensions, with that of the spinor-coupled operator exhibiting non-analytic mass dependence.
Latinas’ Experience of Sexual Assault Disclosure  [PDF]
Melissa Villarreal
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.510140
Abstract:

This study describes Latina’s experience of sexual assault disclosure. This study contributes Latinas’ voices to the literature on sexual assault disclosure, about feelings experienced during the initial disclosure—regret, shame, and negative judgment of self, and about consequences experienced from the disclosure—feeling spoiled for marriage, silenced, and disbelieved. It points to the need for further research on social interventions to empower Latina sexual assault survivors. Although the literature review identified some research in the area of sexual assault with Latinas, there has been a limited amount of research conducted on feelings and consequences experienced specifically by Latinas during a sexual assault disclosure.

Measuring variability in trophic status in the Lake Waco/Bosque River Watershed
Angela D Rodriguez, Marty D Matlock
Journal of Biological Engineering , 2008, DOI: 10.1186/1754-1611-2-1
Abstract: We used the passive diffusion periphytometer to measure in-situ nutrient limitation and trophic status at eight sites in five streams in the Lake Waco/Bosque River Watershed in north-central Texas from July 1997 through October 1998. The chlorophyll a production in the periphytometers was used as an indicator of baseline chlorophyll a productivity and of maximum primary productivity (MPP) in response to nutrient enrichment (nitrogen and phosphorus). We evaluated the lotic ecosystem trophic status index (LETSI) using the ratio of baseline primary productivity to MPP, and evaluated the trophic class of each site.The rivers and streams in the Lake Waco/Bosque River Watershed exhibited varying degrees of nutrient enrichment over the 18-month sampling period. The North Bosque River at the headwaters (NB-02) located below the Stephenville, Texas wastewater treatment outfall consistently exhibited the highest degree of water quality impact due to nutrient enrichment. Sites at the outlet of the watershed (NB-04 and NB-05) were the next most enriched sites. Trophic class varied for enriched sites over seasons.Seasonality played a significant role in the trophic class and sensitivity of each site to nutrients. Managing rivers and streams for nutrients will require methods for measuring in situ responses and sensitivities to nutrient enrichment. Nutrient enrichment periphytometers show significant potential for use in nutrient gradient studies.Algae have been used to determine stream ecosystem impacts from human activities for more than 50 years [1]. Increased loading of nutrients into streams and lakes has become one the major environmental problems facing society today [2,3]. Nutrients are the leading cause for the degradation of water quality in lakes and estuaries in the US and second to siltation among the Nation's rivers and streams [3]. Nutrients released from runoff into an aquatic ecosystem stimulate algal growth and hence accelerates the eutrophication of surface wat
High-frequency dynamical response of Abrikosov vortex lattice in flux-flow region
F. Pei-Jen Lin,Peter Matlock
Physics , 2010, DOI: 10.1103/PhysRevB.82.024516
Abstract: The dynamical response of the Abrikosov vortex lattice in the presence of an oscillating driving field is calculated by constructing an analytical solution of the time-dependent Ginzburg-Landau equation. The solution is steady-state, and work done by the input signal is dissipated through vortex cores, mainly by scattering with phonons. The response is nonlinear in the input signal, and is verified for consistency within the theory. The existence of well-defined parameters to control nonlinear effects is important for any practical application in electronics, and a normalised distance from the normal-superconducting phase-transition boundary is found to be such a parameter to which the response is sensitive. Favourable comparison with NbN experimental data in the optical region is made, where the effect is in the linear regime. Predictions are put forward regarding the suppression of heating and also the lattice configuration at high frequency.
Universality of correction to Luescher term in Polchinski-Strominger effective string theories
N. D. Hari Dass,Peter Matlock
Physics , 2006,
Abstract: We show, by explicit calculation, that the next correction to the universal Luescher term in the effective string theories of Polchinski and Strominger is also universal. We find that to this order in inverse string-length, the ground-state energy as well as the excited-state energies are the same as those given by the Nambu-Goto string theory, the difference being that while the Nambu-Goto theory is inconsistent outside the critical dimension, the Polchinski-Strominger theory is by construction consistent for any space-time dimension. Our calculation explicitly avoids the use of any field redefinitions as they bring in many other issues that are likely to obscure the main points.
Covariant Calculus for Effective String Theories
N. D. Hari Dass,Peter Matlock
Physics , 2007,
Abstract: A covariant calculus for the construction of effective string theories is developed. Effective string theory, describing quantum string-like excitations in arbitrary dimension, has in the past been constructed using the principles of conformal field theory, but not in a systematic way. Using the freedom of choice of field definition, a particular field definition is made in a systematic way to allow an explicit construction of effective string theories with manifest exact conformal symmetry. The impossibility of a manifestly invariant description of the Polchinski-Strominger Lagrangian is demonstrated and its meaning is explained.
