Thou Shall Not Kill: Vegetarianism in the Christian Faith

Biblical justifications for a vegetarian diet seem to meet with much adversity within mainstream American culture. Texts suggesting that people were intended to be vegetarians can be found in the Bible. However, this interpretation of Biblical texts has not been widely accepted by Protestant Christianity. This research attempts to identifY social and religious characteristics of people who are vegetarian. Fundamentalism, denomination, belief in the inerrancy of the Bible, and strength of belief in Christianity are examined as factors related to supporting vegetarianism. The General Social Survey's data from 1993 and 1994 were used in this study. The data were analyzed using frequencies, means, cross tabulations. correlations, and regressions. The sample was 57% female and 87% white, the mean age was 46 and the average level of education was 13 years. The study found that, among the independent variables. belief in animal rights, rather than any specific religious views, had the strongest influence on vegetarianism.

Matt Christopher Papers - Accession 1092

The Matt Christopher Papers consist of published manuscripts, published short stories (1943-1994) (drafts, synopses, plot outlines, and magazines, comics, and newspapers with articles and short stories), galleys (1954-1990s), leather bound author’s editions (1954-1991), and publisher’s editions of Matt Christopher’s children’s books (1954-2004). The collection contains many unpublished manuscripts and drafts outside the children’s book field (1954-1997), unpublished poems (1938-1993), unpublished screenplays (1940-1997), and unpublished short stories (1954-1997). Also included are taped (audio and video) interviews of Matt Christopher, as well as, puzzles for children (1988-1992), research materials and notes (1954-1997), sports rule-books (1954-1995), and writing guides (1909-1995), personal (1949-1997) and business correspondence (1952-2002), contract agreements (1952-1993), royalty statements (1954-1999), and biographical information (1917-2004), memorabilia (personalized baseball bat, framed pictures and award certificates, etc.), fan mail (1964-1999) and his personal book collection (1847-1995) (some signed by authors).

Book Review of Discovering North American Rock Art Edited by Lawrence L. Loendorf, Christopher Chippindale, and David S. Whitley

If readers of Great Plains Research are seeking a window on rock art research in North America, this book provides a few clear panes, a few that are hazy, and a few muddy ones. Like many edited volumes, the weaker contributions and lack of a consistent style limit the book's usefulness. Some authors target a general readership; others clearly are addressing colleagues. The book has two stated themes: the history of rock art research in North America and recent approaches to rock art analysis. Articles by Julie Francis and (jointly) David Whitley and Jean Clottes explore why rock art research has long been marginalized in North America. Unfortunately, both of these otherwise observant essays slip into advocacy of shamanism as a unifying or primary explanation for rock art, an interpretive model by no means universally accepted by today's rock art specialists.

Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

Measurement of prompt J/psi and beauty hadron production cross sections at mid-rapidity in pp collisions at root s=7 TeV

The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.
