A Long and Winding Road: Federally Qualified Health Centers, Community Variation and Prospects Under Reform
Outlines growth in the number of, demand, and federal funding for FQHCs between 1997 and 2009 in twelve communities and factors that shape FQHC development, including variations in Medicaid eligibility rules, employer-sponsored coverage, and demographics
Pointing-error simulations of the DSS-13 antenna due to wind disturbances
Accurate spacecraft tracking by the NASA Deep Space Network (DSN) antennas must be assured during changing weather conditions. Wind disturbances are the main source of tracking errors. The development of a wind-force model and simulations of wind-induced pointing errors of DSN antennas are presented. The antenna model includes the antenna structure, the elevation and azimuth servos, and the tracking controller. Simulation results show that pointing errors due to wind gusts are of the same order as errors due to static wind pressure and that these errors (similar to those of static wind pressure) satisfy the velocity quadratic law. The presented methodology is used for wind-disturbance estimation and for the design of an antenna controller with wind-disturbance rejection properties
Links Between Social Support, Thwarted Belongingness, and Suicide Ideation among Lesbian, Gay, and Bisexual College Students
Emerging adults with a lesbian, gay, or bisexual (LGB) identity are at greater risk for engaging in suicide-related behaviors. This disparity highlights a need to elucidate specific risk and protective factors associated with suicide-related behaviors among LGB youth, which could be utilized as targets for suicide prevention efforts in this population. Informed by the interpersonal-psychological theory of suicide, the present study hypothesized that social support would be indirectly associated with decreased suicide ideation via lower thwarted belongingness. A sample of 50 emerging adults (62.0% male, 70.0% Hispanic) who identified as gay, lesbian, bisexual, questioning, or âotherâ orientation, with a mean age of 20.84 years (SD = 3.30 years), completed self-report assessments. Results indicated that support from both family and the LGB community were associated with lower thwarted belongingness over and above the effects of age, sex, and depressive symptoms. Indirect effects models also indicated that both family and LGB community support were associated with suicide ideation via thwarted belongingness. The results of the present study suggest that family and LGB community support may represent specific targets for reducing thwarted belongingness that could be leveraged in suicide prevention efforts for LGB emerging adults
Botaiho : Japanese organised crime under the Boryokudan countermeasures law
This thesis is an investigation into the effects of the 1992 böryokudan
countermeasures law (böryokudan taisaku ha or, more simply, bötaihö) on Japan's
organised crime syndicates (böryokudan or yakuza). Underlying this examination is a
functionalist perspective of organised crime which rests on the premise that, far from
being unambiguously socially dysfunctional, organised crime groups exist because they satisfy needs held by various sections of society (both in the upper and underworlds).
This approach demystifies many of the supposedly unique aspects of the böryokudan/yakuza (such as yakuza-authority symbiosis) and places Japan within the
compass of modem organised-crime studies. An empirical overview of the böryokudan's development from 1945 to 1992 shows that the prime dynamic behind this evolution has been the legal and law-enforcement environment within which these groups exist and that frequently the impact of these changes has been socially undesirable. Attempts to examine whether or not the bötaihö has similarly exacerbated organised criminality in Japan are hampered by the collapse of Japan's bubble economy in 1990. This event had profound consequences for boryokudan
groups rendering many activities unviable, whilst simultaneously creating new
opportunities. Despite these extraneous considerations, the bötaihö has had an
observable impact on many aspects of the böryokudan's activities and some of these
consequences have been socially undesirable. The legal analysis of the bötaihö is placed in the wider context of international organised-crime control measures, in
particular America's RICO statutes and European laws, both of which were highly
influential in the debate within Japan concerning the framing of new anti-böryokudan
laws. The thesis concludes by arguing that the radically different structure of the
bötaihö, vis-À-vis these alternative models, is part of a wider reversion to pre-war
legal and policing norms in which, in addition to enforcement of the criminal law, the police also exercise considerable administrative powers
Molar mass and solution conformation of branched alpha(1 - 4), alpha(1 - 6) Glucans. Part I: Glycogens in water
Solution molar masses and conformations of glycogens from different sources (rabbit, oyster, mussel and bovine) were analysed using sedimentation velocity in the analytical ultracentrifuge, size-exclusion chromatography coupled to multi-angle laser light scattering (SEC-MALLS), size-exclusion chromatography coupled to a differential pressure viscometer and dynamic light scattering. Rabbit, oyster and mussel glycogens consisted of one population of high molar mass (weight averages ranging from 4.6 x 106 to 1.1 x 107 g/mol) as demonstrated by sedimentation velocity and SEC-MALLS, whereas bovine glycogen had a bimodal distribution of significantly lower molar mass (1.0 x 105 and 4.5 x 105 g/mol). The spherical structure of all glycogen molecules was demonstrated in the slopes of the Mark-Houwink-Kuhn-Sakurada-type power-law relations for sedimentation coefficient (s20,wo), intrinsic viscosity ([Ă·]), radius of gyration (rg,z) and radius of hydration (rH,z), respectively, and was further supported by the Ăïżœ (=rg,z/rH,z) function, the fractal dimension and the Perrin function. The degree of branching was estimated to be ĂąËÂŒ10% from the shrinking factors, gĂąâŹÂČ (=[Ă·]branched/[Ă·]linear) and also h (=(f/fo)branched/(f/fo)linear), respectively, where (f/fo) is the translational frictional ratio, consistent with expectation.

XMM-Newton and INTEGRAL analysis of the Supergiant Fast X-ray Transient IGR J17354-3255
We present the results of combined INTEGRAL and XMM-Newton observations of
the supergiant fast X-ray transient (SFXT) IGR J173543255. Three XMM-Newton
observations of lengths 33.4 ks, 32.5 ks and 21.9 ks were undertaken, the first
an initial pointing to identify the correct source in the field of view and the
latter two performed around periastron. Simultaneous INTEGRAL observations
across of the orbital cycle were analysed but the source was neither
detected by IBIS/ISGRI nor by JEM-X. The XMM-Newton light curves display a
range of moderately bright X-ray activity but there are no particularly strong
flares or outbursts in any of the three observations. We show that the spectral
shape measured by XMM-Newton can be fitted by a consistent model throughout the
observation, suggesting that the observed flux variations are driven by
obscuration from a wind of varying density rather than changes in accretion
mode. The simultaneous INTEGRAL data rule out simple extrapolation of the
simple powerlaw model beyond the XMM-Newton energy range.Comment: 13 pages, 9 figures, This article has been accepted for publication

Neutral top-pion and the rare top decays
We study the rare top decays in the
framework of topcolor-assisted technicolor() models. We find that the
neutral top-pion can produce significant contributions to these
processes via the flavor changing couplings and
