The Federal Waste Water Treatment System Construction Grant Program: What It Requires of States and How It Works

This paper is the result of a study conducted to inform the author as to how the Environmental Protection Agency (EPA) relates to state and intrastate programs that deal with waste water treatment systems in a coastal state. The investigation centered on how EPA actually manages its functions and assistance directed towards state-level and local-level efforts to control sewage treatment facilities. The study was not limited only to the federal-to-state-flow dynamics. It also looked at areas of purely state function, state-to-local flow, and also the opposite situation of local-to-sate-to-federal oriented inputs

Group Self‐Interest vs. Equity:Explaining Support for Horizontal Redistribution in (Former) Competitive Clientelist States

Extant literature links intergroup disparities, or horizontal inequalities, in Sub‐Saharan Africa to the unequal representation of ethnic groups in central power, who accumulate wealth at the expense of politically marginalized groups. Over time, these politically‐induced inequalities have trapped some ethnic groups in positions of relative disadvantage. Group‐based, or horizontal, redistribution can help redress these inequalities yet require popular support if they are not to contribute to intergroup tensions. In this article, we examine how people’s experiences of political exclusion, on the one hand, and their attributional beliefs about the causes of political exclusion, on the other, condition support for government policies aimed at eradicating economic inequalities between different ethnic groups. We argue that people are more likely to be supportive of horizontal redistribution either when (H1a) they belong to ethnic groups that have not had access to central power, and/or (H1b) feel that their ethnic group is politically marginalized (and thus stands to gain); or when (H2) they attribute the political exclusion of the politically marginalized group(s) that stand(s) to benefit from these policies to the legacies of colonialism and clientelism (thus seeking to foster equity). To test our hypotheses, we examine these issues in the context of Kenya, a society with politically salient ethnic cleavages and a history of clientelism. Based on a unique online survey involving 2,286 Kenyans, we show that, notwithstanding group self‐interest being at play, there is strong support for horizontal redistribution across groups

Satellite power system: Concept development and evaluation program. Volume 3: Power transmission and reception. Technical summary and assessment

Efforts in the DOE/NASA concept development and evaluation program are discussed for the solar power satellite power transmission and reception system. A technical summary is provided together with a summary of system assessment activities. System options and system definition drivers are described. Major system assessment activities were in support of the reference system definition, solid state system studies, critical technology supporting investigations, and various system and subsystem tradeoffs. These activities are described together with reference system updates and alternative concepts for each of the subsystem areas. Conclusions reached as a result of the numerous analytical and experimental evaluations are presented. Remaining issues for a possible follow-on program are identified

Closed-cycle, low-vibration 4 K cryostat for ion traps and other applications

In-vacuo cryogenic environments are ideal for applications requiring both low temperatures and extremely low particle densities. This enables reaching long storage and coherence times for example in ion traps, essential requirements for experiments with highly charged ions, quantum computation, and optical clocks. We have developed a novel cryostat continuously refrigerated with a pulse-tube cryocooler and providing the lowest vibration level reported for such a closed-cycle system with 1 W cooling power for a <5 K experiment. A decoupling system suppresses vibrations from the cryocooler by three orders of magnitude down to a level of 10 nm peak amplitudes in the horizontal plane. Heat loads of about 40 W (at 45 K) and 1 W (at 4 K) are transferred from an experimental chamber, mounted on an optical table, to the cryocooler through a vacuum-insulated massive 120 kg inertial copper pendulum. The 1.4 m long pendulum allows installation of the cryocooler in a separate, acoustically isolated machine room. In the laser laboratory, we measured the residual vibrations using an interferometric setup. The positioning of the 4 K elements is reproduced to better than a few micrometer after a full thermal cycle to room temperature. Extreme high vacuum on the $10^{-15}$ mbar level is achieved. In collaboration with the Max-Planck-Intitut f\"ur Kernphysik (MPIK), such a setup is now in operation at the Physikalisch-Technische Bundesanstalt (PTB) for a next-generation optical clock experiment using highly charged ions
