Military as Welfare State: Conditions Leading to the Adoption of the National Guard Youth ChalleNGe Program

Since its inception in 1993, nearly 90,000 high school dropouts have completed the National Guard Youth Challenge Program, a youth diversion program for unemployed high school dropouts. As of 2008, 27 states have partnered with the military to implement this residential program for at-risk youth. There is limited research on this new social welfare program despite its representing a dynamic military-state-welfare relationship. This study examines state-level conditions and looks to answer three research questions: 1) Under what conditions do states start a ChalleNGe program?; 2) What role do time-varying social and economic factors have in influencing states to initially adopt the program?; and 3) To what extent does the racial composition of program sites reflect the racial composition of its host state\u27s young high school drop-outs? I examined state-level social and economic conditions using data from a variety of federal agencies and public opinion surveys. I examined social and economic circumstances that may have influenced state-level participation. Due to the nature of time-dependent variables and states\u27 launching programs as various times since 1993, I used an event history analysis to predict the timing of initiation of a ChalleNGe program. The results of this research indicate that high unemployment rates and low high school graduation rates increase the likelihood that a state will create a ChalleNGe program. The results from this study provide insight into the creation and expansion of the ChalleNGe program as well as the changing role of military as a part of the welfare state

Contrasting the capabilities of building energy performance simulation programs

For the past 50 years, a wide variety of building energy simulation programs have been developed, enhanced and are in use throughout the building energy community. This paper is an overview of a report, which provides up-to-date comparison of the features and capabilities of twenty major building energy simulation programs. The comparison is based on information provided by the program developers in the following categories: general modeling features; zone loads; building envelope and daylighting and solar; infiltration, ventilation and multizone airflow; renewable energy systems; electrical systems and equipment; HVAC systems; HVAC equipment; environmental emissions; economic evaluation; climate data availability, results reporting; validation; and user interface, links to other programs, and availability

‘So people know I'm a Sikh’: Narratives of Sikh masculinities in contemporary Britain

This article examines British-born Sikh men's identification to Sikhism. In particular, it focuses on the appropriation and use of Sikh symbols amongst men who define themselves as Sikh. This article suggests that whilst there are multiple ways of ‘being’ a Sikh man in contemporary post-colonial Britain, and marking belonging to the Sikh faith, there is also a collectively understood idea of what an ‘ideal’ Sikh man should be. Drawing upon Connell and Messerschmidt's discussion of locally specific hegemonic masculinities (2005. “Hegemonic Masculinity: Rethinking the Concept.” Gender and Society 19 (6): 829–859), it is suggested that an ideal Sikh masculine identity is partly informed by a Khalsa discourse, which informs a particular performance of Sikh male identity, whilst also encouraging the surveillance of young men's activities both by themselves and by others. These Sikh masculinities are complex and multiple, rotating to reaffirm, challenge and redefine contextualised notions of hegemonic masculinity within the Sikh diaspora in post-colonial Britain. Such localised Sikh masculinities may both assert male privilege and reap patriarchal dividends (Connell, W. 1995. Masculinities. Cambridge: Polity Press), resulting in particular British Sikh hegemonic masculinities which seek to shape the performance of masculinity, yet in another context these very same performances of masculinity may also signify a more marginalised masculinity vis-à-vis other dominant hegemonic forms

Effects of a Beaver Pond in Southwestern Montana on Metals Concentrations and Loads

A 400-m2 beaver pond on Cabbage Gulch (Deer Lodge County, MT) was investigated for its retention of total recoverable (TR) and dissolved arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), and total suspended solids (TSS) during three storm water runoff events in the summer of 2013. Water samples were collected and flow rates were measured at monitoring stations above and below the pond. Decreases in TR metals concentrations were -17 percent for As (that is, As concentrations increased), 10 percent for Cu, 7 percent for Pb, and 27 percent for Zn. Total recoverable metals retained in the pond, on a mass basis, were 24 percent for As, 47 percent for Cu, 45 percent for Pb, and 55 percent for Zn. The average retention was 49 percent (by mass) for TR Cu, Pb, and Zn. Twenty-four percent of the influent TR Cu and TR Zn loads were retained because the metals were suspended in the pond with stored storm water. An additional 27 percent of the influent TR Cu and TR Zn loads settled out of the water during the sampling periods. Arsenic retention was low because all of the As was in the dissolved phase and no As could settle out. Total suspended solids concentrations decreased by 2 percent and TSS mass retention was 41 percent

In which shell-type SNRs should we look for gamma-rays and neutrinos from p-p collisions?

We present a simple analytic model for the various contributions to the non-thermal emission from shell type SNRs, and show that this model's results reproduce well the results of previous detailed calculations. We show that the \geq 1 TeV gamma ray emission from the shell type SNRs RX J1713.7-3946 and RX J0852.0-4622 is dominated by inverse-Compton scattering of CMB photons (and possibly infra-red ambient photons) by accelerated electrons. Pion decay (due to proton-proton collisions) is shown to account for only a small fraction, \lesssim10^-2, of the observed flux, as assuming a larger fractional contribution would imply nonthermal radio and X-ray synchrotron emission and thermal X-ray Bremsstrahlung emission that far exceed the observed radio and X-ray fluxes. Models where pion decay dominates the \geq 1 TeV flux avoid the implied excessive synchrotron emission (but not the implied excessive thermal X-ray Bremsstrahlung emission) by assuming an extremely low efficiency of electron acceleration, K_ep \lesssim 10^-4 (K_ep is the ratio of the number of accelerated electrons and the number of accelerated protons at a given energy). We argue that observations of SNRs in nearby galaxies imply a lower limit of K_ep \gtrsim 10^-3, and thus rule out K_ep values \lesssim 10^-4 (assuming that SNRs share a common typical value of K_ep). It is suggested that SNRs with strong thermal X-ray emission, rather than strong non-thermal X-ray emission, are more suitable candidates for searches of gamma rays and neutrinos resulting from proton-proton collisions. In particular, it is shown that the neutrino flux from the SNRs above is probably too low to be detected by current and planned neutrino observatories (Abridged).Comment: 13 pages, 1 figure, accepted for publication in JCAP, minor revision

Modeling the power flow in normal conductor-insulator-superconductor junctions

Normal conductor-insulator-superconductor (NIS) junctions promise to be interesting for x-ray and phonon sensing applications, in particular due to the expected self-cooling of the N electrode by the tunneling current. Such cooling would enable the operation of the active element of the sensor below the cryostat temperature and at a correspondingly higher sensitivity. It would also allow the use of MS junctions as microcoolers. At present, this cooling has not been realized in large area junctions (suitable for a number of detector applications). In this article, we discuss a detailed modeling of the heat flow in such junctions; we show how the heat flow into the normal electrode by quasiparticle back-tunneling and phonon absorption from quasiparticle pair recombination can overcompensate the cooling power. This provides a microscopic explanation of the self-heating effects we observe in our large area NIS junctions. The model suggests a number of possible solutions

The Effects of Artificial Destratification on the Water Quality and Microbial Populations of Hyrum Reservoir

Artificial destratification is being increasingly used in attempts to improve water quality and control eutrophication. Most of the artificial destratification efforts are being conducted by public water supply utilities in efforts to improve reservoir water quality for culinary purposes. At present, artificial destratification is being conducted without a complete understanding of the process or its effects on the reservoir. Whether or not artificial destratification can control algal growth and other microbial processes is a controversial question. The effect of artificial destratification on the microbial flora must be understood if it is to be used effectively as a management tool in the control of water quality. In recent years a blue-green algal bloom has developed during the summer in Hyrum Reservoir. The massive bloom of Aphanizomenon jlos-aquae presents esthetic problems to those using the reservoir for recreational purposes. These esthetic problems have reduced the use of the reservoir for swimming, water skiing, and fishing. It is believed that artificial de stratification, or the destruction of natural stratification obtained through diffused-air aeration, will improve the water quality of the reservoir
