    Ideology Versus Reality in the Lunchroom: A Comparative Study of Three School Nutrition Programs

    American children are becoming increasingly overweight and inactive; consequently, the school lunch room is fast becoming an ideological battle ground. Legislators, medical professionals, school districts, parents, and the media are focusing intense scrutiny on school nutrition programs, and sweeping changes to these programs are federally mandated to occur before July, 2006. However, equal scrutiny has not been focused on the actual operations, logistics, or requirements of these programs. Through interviews, on-site visits, and participant observations, this eight week study focuses on current (April through June 2005) conditions in three economically disparate public school nutrition programs in one California county. This study asks if school nutrition programs can implement the numerous changes required under new cultural (informal) and upcoming federal (formal) mandates. The conclusion in this instance is that no, public schools are under too much existent financial, physical plant-related, and personnel-related strain to be able to easily or effectively retool their nutrition programs to match the burgeoning ideology. This study provides recommendations and considerations for schools, parents, and legislators – not from an ideological elevation, but from the actual locations within which our children are being fed

    The Crystal Structure and Conformation of bis(N-methyl-5-chlorosalicylideneiminato)nickel(II) and bis(N-ethyl-5-chlorosalicy lideneiminato)nickel(II)

    The crystal structures of bis(N-methyl-5-chlorosalicylideneiminato) nickel(II) (A) and bis(N-ethyl-5-chlorosalicylideneiminato) nickel(II) (B) have been determined by X-ray structure analysis using heavy atom method and refined by fuU matrix leastsquares procedure to R values of 0.044 and 0.040 for (A) and (B), respectively. Both structures have molecular centre of symmetry and the nickel atom in a planar coordination. Molecules of both complex compounds have »stepped« conformation with distinct difference in the step heights: 0.121 and 0.702 A in (A) and (B), respectively. The Ni-O and Ni-N bond lengths are 1.818 and 1.924 A in (A), and \u271.830 and 1.916 A in (B)

    A migration-associated supergene reveals loss of biocomplexity in Atlantic cod

    Chromosome structural variation may underpin ecologically important intraspecific diversity by reducing recombination within supergenes containing linked, coadapted alleles. Here, we confirm that an ancient chromosomal rearrangement is strongly associated with migratory phenotype and individual genetic structure in Atlantic cod (Gadus morhua) across the Northwest Atlantic. We reconstruct trends in effective population size over the last century and reveal declines in effective population size matching onset of industrialized harvest (after 1950). We find different demographic trajectories between individuals homozygous for the chromosomal rearrangement relative to heterozygous or homozygous individuals for the noninverted haplotype, suggesting different selective histories across the past 150 years. These results illustrate how chromosomal structural diversity can mediate fine-scale genetic, phenotypic, and demographic variation in a highly connected marine species and show how overfishing may have led to loss of biocomplexity within Northern cod stock.Peer reviewe
