Discerning Differences between Producer Groups and Organic Adoption Barriers in Texas
The number of certified organic operations in Texas has remained relatively stagnant while nationally the organic food sector has experienced double-digit growth. To understand why this occurring, a survey was distributed to a random sample of 4,006 Texas producers. The results will assist in developing strategies to promote the growth of organic production in Texas.Crop Production/Industries,
The effect of color in the Rorschach test and in selected intellectual tasks.
Thesis (Ph.D.)--Boston UniversityAn important theoretical basis of the Rorschach test is the assumption that the subject's reactions to specific stimulus qualities of the ink blots, such as form and color, relate to specific personality variables. Our verified knowledge of the function of these various stimuli in perception has been limited. This may be due partly to the adequacy of validation studies which focus on overall interpretations of test results and partly to experimental difficulties in dealing with single variables out of their complex context.
The purpose of this study was to provide an experimental examination of the influence of color in the Rorschach test and in independent performance tasks. [TRUNCATED
LEGAL FRATERNITIES
No exact computation of the number of practicing attorneys who are members of legal fraternities is available. However, well over 120,000 law students have in the past 82 years affiliated with a legal fraternity-no account being taken of the numbers belonging to purely local societies. Since the great majority of these individuals have entered into the practice, it is apparent that the Survey of the Legal Profession would not be exhaustive without some reference to such organizations. Professional Greek-letter fraternities now exist in practically all conceivable fields from Animal Husbandry to Textile Arts. Their legal counterpart furnished the model
Remedies
Remedial problems are best dealt with in the context of substantive law situations. However, the disparate characteristics of restitution, equitable remedies, and damages necessitate some generalized preliminary comment. We regret that the points raised in the California cases during a one-year period do not form a tidy or cohesive pattern or adapt themselves to a symmetrical outline

Conformal ``thin sandwich'' data for the initial-value problem of general relativity
The initial-value problem is posed by giving a conformal three-metric on each
of two nearby spacelike hypersurfaces, their proper-time separation up to a
multiplier to be determined, and the mean (extrinsic) curvature of one slice.
The resulting equations have the {\it same} elliptic form as does the
one-hypersurface formulation. The metrical roots of this form are revealed by a
conformal ``thin sandwich'' viewpoint coupled with the transformation
properties of the lapse function.Comment: 7 pages, RevTe
The Composite Spectrum of Strong Lyman-alpha Forest Absorbers
We present a new method for probing the physical conditions and metal
enrichment of the Intergalactic Medium: the composite spectrum of Ly-alpha
forest absorbers. We apply this technique to a sample of 9480 Ly-alpha
absorbers with redshift 2 < z < 3.5 identified in the spectra of 13,279
high-redshift quasars from the Sloan Digital Sky Survey (SDSS) Fifth Data
Release (DR5). Absorbers are selected as local minima in the spectra with 2.4 <
tau_Ly-alpha < 4.0; at SDSS resolution (~ 150km/s FWHM), these absorbers are
blends of systems that are individually weaker. In the stacked spectra we
detect seven Lyman-series lines and metal lines of O VI, N V, C IV, C III, Si
IV, C II, Al II, Si II, Fe II, Mg II, and O I. Many of these lines have peak
optical depths of < 0.02, but they are nonetheless detected at high statistical
significance. Modeling the Lyman-series measurements implies that our selected
systems have total H I column densities N_HI ~ 10^15.4cm-2. Assuming typical
physical conditions rho / = 10, T = 10^4 - 10^4.5 K, and [Fe/H]= -2
yields reasonable agreement with the line strengths of high-ionization species,
but it underpredicts the low-ionization species by two orders of magnitude or
more. This discrepancy suggests that the low ionization lines arise in dense,
cool, metal-rich clumps, present in some absorption systems.Comment: 7 pages, 4 figures, 1 table, accepted by ApJL, revisions mad
