Social Security Reform: Legal Analysis of Social Security Benefit Entitlement Issues
[Excerpt] Calculations indicating that the current Social Security program will not be financially sustainable in the long run under the present statutory scheme have fueled the current debate regarding Social Security reform. This report addresses selected legal issues that may be raised regarding entitlement to Social Security benefits as Congress considers possible changes to the Social Security program in view of projected long-range shortfalls in the Social Security Trust Funds.
Social Security benefits are administered pursuant to Title II of the Social Security Act, known as the Old Age, Survivors and Disability Insurance (OASDI) program. Title II is part of a larger social insurance program in which Congress uses its power to tax and spend for the general welfare to promote the social goals of aiding the aged, survivors of workers, disabled persons, and persons of limited means. Beneficiaries under Title II have a legal entitlement to receive Social Security benefits as set forth by the Social Security Act and as administered by the Social Security Administration (SSA), an independent agency in the executive branch.
An individualâs right to Social Security benefits is in a sense âearned,â since there is a general relationship between OASDI benefits and wages earned and the tax paid thereon. However, benefits are not directly measured by the amount of payments made through the years into the system. Thus, the fact that Social Security benefits are financed by taxes on an employeeâs wages does not provide a limit on Congressâs power to fix the levels of benefits under the Social Security Act, or the conditions upon which they may be paid
Dark matter cores in the Fornax and Sculptor dwarf galaxies: joining halo assembly and detailed star formation histories
We combine the detailed Star Formation Histories of the Fornax and Sculptor
dwarf Spheroidals with the Mass Assembly History of their dark matter (DM) halo
progenitors to estimate if the energy deposited by Supernova type II (SNeII) is
sufficient to create a substantial DM core. Assuming the efficiency of energy
injection of the SNeII into DM particles is , we find
that a single early episode, , that combines the
energy of all SNeII due to explode over 0.5 Gyr, is sufficient to create a core
of several hundred parsecs in both Sculptor and Fornax. Therefore, our results
suggest that it is energetically plausible to form cores in Cold Dark Matter
(CDM) halos via early episodic gas outflows triggered by SNeII. Furthermore,
based on CDM merger rates and phase-space density considerations, we argue that
the probability of a subsequent complete regeneration of the cusp is small for
a substantial fraction of dwarf-size haloes.Comment: ApJL accepted versio
Firing Up Craft Capital: The renaissance of craft and craft policy in the United Kingdom
Firing Up Craft Capital: The renaissance of craft and craft policy in the United Kingdom, This article was accepted for publication on the 23rd June 2015. Final published version published online 20 October 2015.Crafts have recently been experiencing a renaissance. This revitalization sees craft increasingly recognised as a growing industrial sector with benefits linked to educational, cultural and economic development policy agendas. This paper engages with policy debates around the place of craft in the United Kingdom from 2010. Drawing on craft sector perspectives and UK government policy initiatives it situates the disciplines and practices of craft within their institutional support networks, organizational contexts and draws attention to the role of individuals in driving agendas. The paper focuses on the national facing crafts development organizations, the UK Crafts Council and the UK Heritage Crafts Association, alongside recent policy discussion emerging from the UK Department for Business, Innovation and Skills. Recognizing that the legacies of past practice often inform contemporary agendas, the paper explores how the advocacy of craft in the recent past has shaped the place and positioning of craft in contemporary UK politics.This work was supported by the UK Arts and Humanities Research Council under Grant AH/I001778/1
The habitability of stagnant-lid Earths around dwarf stars
The habitability of a planet depends on various factors, such as delivery of
water during the formation, the co-evolution of the interior and the
atmosphere, as well as the stellar irradiation which changes in time. Since an
unknown number of rocky exoplanets may operate in a one-plate convective
regime, i.e., without plate tectonics, we aim at understanding under which
conditions planets in such a stagnant-lid regime may support habitable surface
conditions. Understanding the interaction of the planetary interior and
outgassing of volatiles with the atmosphere in combination with the evolution
of the host star is crucial to determine the potential habitability. M-dwarf
stars in particular possess a high-luminosity pre-main sequence phase which
endangers the habitability of planets around them via water loss. We therefore
explore the potential of secondary outgassing from the planetary interior to
rebuild a water reservoir allowing for habitability at a later stage. We
compute the boundaries of the habitable zone around M, K, G, and F-dwarf stars
using a 1D cloud-free radiative-convective climate model accounting for the
outgassing history of CO2 and H2O from an interior evolution and outgassing
model for different interior compositions and stellar luminosity evolutions.
The outer edge of the habitable zone strongly depends on the amount of CO2
outgassed from the interior, while the inner edge is mainly determined via the
stellar irradiation, as soon as a sufficiently large water reservoir has been
outgassed. A build-up of a secondary water reservoir for planets around M-dwarf
stars is possible even after severe water loss during the high luminosity
pre-main sequence phase as long as some water has been retained within the
mantle. Earth-like stagnant-lid planets allow for habitable surface conditions
within a continuous habitable zone that is dependent on interior composition.Comment: 15 pages, accepted by A&A, abstract shortene

VA Accountability Act of 2015 (H.R. 1994), as Reported to the House
[Excerpt] This report describes the VA Accountability Act of 2015 (H.R. 1994) as reported to the House by the Committee on Veterans Affairs on July 23 2015 and compares it to current law where appropriate. A press account has reported that Chairman Jeff Miller may meet with all committee members to seek views of the minority before floor action. As a result of this meeting, it is possible that the final bill that will go to the House floor may have some provisions that differ from those that the Committee reported.
This report provides a section-by-section description of the act

Debate: The development of a new disciplineâ public service operations management
This piece aims to outline the development of a discipline â Public Service Operations Management and will argue the importance of developing an understanding between public management and operations management literature and theory This is reflected through the recent publication of an edited companion which aspires to explore and define bodies of knowledge related to Public Service Operations Managemen
An individual-based profitability spectrum for understanding interactions between predators and their prey
There is confusion in the animal behaviour literature over the use of the terms âtoxicityâ and âunpalatabilityâ, which are commonly used interchangeably when describing the function of chemical compounds in prey, although these terms describe very different functions. Toxic chemicals cause fitness-reducing harm, whereas unpalatability provides aversive taste but no reduction in fitness. Furthermore, chemical defences are only one aspect of prey profitability. We argue that if predators are maximizing fitness, all prey can be described in terms of their costs and benefits to predators across all currencies, giving each prey item a positive or negative position on a âprofitability spectrumâ. Adaptively foraging predators should be selected to eat only prey with a positive profitability. The context of each predatorâprey encounter also alters the profitability of the prey. Given that profitability is a function of the current state of both the predator and the prey individuals, we explain why it should be considered to be an attribute of a particular encounter, in contrast to its present usage as an attribute of a prey species. This individual-centred perspective requires researchers to investigate, through both theoretical models and empirical studies, the complex conditions in which predators and prey meet in real life
