Economic Implications of the Transfer of Functions Legislation
Recent introduction of HB 4780 and its companion pieces of legislation (HB 4781-4788) has raised a number of questions about the appropriate level of government to deliver services to Michigan residents. Essentially, under provisions contained in the bill, elections, tax collections, and assessment functions would be transferred from "rural" townships to the county where the township is located. The bill defines a rural township as a township or charter township unit with population less than 10 thousand, or population between 10 and 20 thousand but does not provide police and fire on a 24-hour basis and sewer and water services to more than 50% of its residents. The Michigan Township Association (MTA) expects that 95% of Michigan townships would be subject to this legislation.Public Economics,

Investigating the relationship between material properties and laser-induced damage threshold of dielectric optical coatings at 1064 nm
The Laser Induced Damage Threshold (LIDT) and material properties of various multi-layer amorphous dielectric
optical coatings, including Nb2O5, Ta2O5, SiO2, TiO2, ZrO2, AlN, SiN, LiF and ZnSe, have been studied. The coatings
were produced by ion assisted electron beam and thermal evaporation; and RF and DC magnetron sputtering at Helia
Photonics Ltd, Livingston, UK. The coatings were characterized by optical absorption measurements at 1064 nm by
Photothermal Common-path Interferometry (PCI). Surface roughness and damage pits were analyzed using atomic force
microscopy. LIDT measurements were carried out at 1064 nm, with a pulse duration of 9.6 ns and repetition rate of 100
Hz, in both 1000-on-1 and 1-on-1 regimes. The relationship between optical absorption, LIDT and post-deposition heattreatment
is discussed, along with analysis of the surface morphology of the LIDT damage sites showing both coating
and substrate failure
Foundations in Wisconsin: A Directory [31st ed. 2012]
The 2012 release of Foundations in Wisconsin marks the 31st edition of the print directory and the twelfth year of the online version. The directory is designed as a research tool for grantseekers interested in locating information on private, corporate, and community foundations registered in Wisconsin. Each entry in this new edition has been updated or reviewed to provide the most current information available. Most of the data was drawn from IRS 990-PF tax returns filed by the foundations. Additional information was obtained from surveys, foundation Web sites, annual reports, and newsletters.
Fortunately, Wisconsin foundations are rebounding from the recent economic downturn. While the total number of active foundations (1301) decreased slightly from 2011’s high number, 57 new foundations were identified and two key measures show positive growth. Total assets increased by 12% from last year to over 490 million, close to pre-recession totals. The following table illustrates the 10-year financial pattern as documented in Foundations in Wisconsin.https://epublications.marquette.edu/lib_fiw/1010/thumbnail.jp
cDNA-RNA subtractive hybridization reveals increased expression of mycocerosic acid synthase in intracellular Mycobacterium bovis BCG.
Identifying genes that are differentially expressed by Mycobacterium bovis BCG after phagocytosis by macrophages will facilitate the understanding of the molecular mechanisms of host cell-intracellular pathogen interactions. To identify such genes a cDNA-total RNA subtractive hybridization strategy has been used that circumvents the problems both of limited availability of bacterial RNA from models of infection and the high rRNA backgrounds in total bacterial RNA. The subtraction products were used to screen a high-density gridded Mycobacterium tuberculosis genomic library. Sequence data were obtained from 19 differential clones, five of which contained overlapping sequences for the gene encoding mycocerosic acid synthase (mas). Mas is an enzyme involved in the synthesis of multi-methylated long-chain fatty acids that are part of phthiocerol dimycocerosate, a major component of the complex mycobacterial cell wall. Northern blotting and primer extension data confirmed up-regulation of mas in intracellular mycobacteria and also revealed a putative extended -10 promoter structure and a long untranslated upstream region 5' of the mas transcripts, containing predicted double-stranded structures. Furthermore, clones containing overlapping sequences for furB, groEL-2, rplE and fadD28 were identified and the up-regulation of these genes was confirmed by Northern blot analysis. The cDNA-RNA subtractive hybridization enrichment and high density gridded library screening, combined with selective extraction of bacterial mRNA represents a valuable approach to the identification of genes expressed during intra-macrophage residence for bacteria such as M. bovis BCG and the pathogenic mycobacterium, M. tuberculosis
Cosmic Variance in CMB Anisotropies: From to COBE
Cosmic Microwave Background (CMB) anisotropies that result from quantum
fluctuations during inflation are explored and the impact of their ``cosmic
variance'' on the ability to use existing data to probe inflationary models is
studied. We calculate the rms temperature fluctuation, and its cosmic variance,
for a number of experiments and for models with primordial power spectra which
range from to . We find: (1) cosmic variance obscures the
information which can be extracted, so a comparison of the rms temperature
fluctuation on small scales with the COBE result can fix to only
at best; (2) measurements of the rms fluctuation on
scales may not allow one to unambiguously infer the tensor
contribution to the COBE anisotropy; (3) comparison of this contribution with
the predictions of inflation are ambiguous if the quadrupole anisotropy alone
is utilized. We discuss means for minimizing the uncertainty due to cosmic
variance in comparisons between experiments.Comment: LaTeX, 18 pages, 6 figures (PostScript). CfPA-TH-93-01, YCTP-P44-92.

Exact longitudinal plasmon dispersion relations for one and two dimensional Wigner crystals
We derive the exact longitudinal plasmon dispersion relations, of
classical one and two dimensional Wigner crystals at T=0 from the real space
equations of motion, of which properly accounts for the full unscreened Coulomb
interactions. We make use of the polylogarithm function in order to evaluate
the infinite lattice sums of the electrostatic force constants. From our exact
results we recover the correct long-wavelength behavior of previous approximate
methods. In 1D, , validating the known
RPA and bosonization form. In 2D , agreeing remarkably
with the celebrated Ewald summation result. Additionally, we extend this
analysis to calculate the band structure of tight-binding models of
non-interacting electrons with arbitrary power law hopping.Comment: 4 pages, 1 figure. Important typos and errors fixed, 2D dispersion
