Autocracy, democracy, bureaucracy, or monopoly: can you judge a government by its size?

We develop a simple theoretical framework to examine on an integrated basis how the form of government affects its power and size. The analytical framework abstracts from distortions that arise from the means ofgovernment finance and separates government power into two dimensions-pure coercive power and pure monopoly power. A government can exert its coercive power to shift the demand for its services outward and/or its monopoly power to restrict the output along a given demand curve to earn rents. Among the implications drawn from the analysis are that government officials have an incentive to provide a non-optimal combination of taxes and services, and that neither size nor rents alone are reliable indicators of the extent to which government fails to achieve optimality in its provision of services.Finance ; Power resources

The Role of Infectious and Stress-related Onsets in Myalgic Encephalomyelitis and Chronic Fatigue Syndrome Symptomatology and Functioning

This study examined how the mode of onset for myalgic encephalomyelitis and chronic fatigue syndrome (ME and CFS) impacts patients’ presenting symptomatology. Specifically, this study investigated the differences between the most commonly reported ME and CFS onsets: infectious, stress-related, and a combined infectious and stress-related onset (referred to as ‘combined onset’). Three patient samples were combined and utilized. All participants met Fukuda et al. (1994) criteria and self-reported their illness onset. Analyses showed the infectious group reported the most impairment for general health functioning—which relates to the susceptibility of getting or feeling sick—in comparison to the stress-related group. Meanwhile, both the stress-related and combined groups reported more impairment for mental health functioning than the infectious group. Lastly, the infectious and combined groups reported worse autonomic and immune symptomatology than the stress group. These findings illustrate that the mode of onset for ME and CFS could play a factor in a patient’s prognosis. An infectious onset might lead to worse physical and somatic symptoms, while a stress onset might lead to worse psychological functioning. These findings are consistent with prior research. Future research should continue investigating the differences amongst patients based on illness onset, as well as other factors (e.g., psychiatric co-morbidity)

The Primeval Populations of the Ultra-Faint Dwarf Galaxies

We present new constraints on the star formation histories of the ultra-faint dwarf (UFD) galaxies, using deep photometry obtained with the Hubble Space Telescope (HST). A galaxy class recently discovered in the Sloan Digital Sky Survey, the UFDs appear to be an extension of the classical dwarf spheroidals to low luminosities, offering a new front in efforts to understand the missing satellite problem. They are the least luminous, most dark-matter dominated, and least chemically-evolved galaxies known. Our HST survey of six UFDs seeks to determine if these galaxies are true fossils from the early universe. We present here the preliminary analysis of three UFD galaxies: Hercules, Leo IV, and Ursa Major I. Classical dwarf spheroidals of the Local Group exhibit extended star formation histories, but these three Milky Way satellites are at least as old as the ancient globular cluster M92, with no evidence for intermediate-age populations. Their ages also appear to be synchronized to within ~1 Gyr of each other, as might be expected if their star formation was truncated by a global event, such as reionization.Comment: Accepted for publication in The Astrophysical Journal Letters.

A Positive Relationship Between Religious Faith and Forgiveness: Faith in the Absence of Data?

Religious faith and beliefs appear to play an important role in the lives of many individuals and are the topic of much research. The present study investigated the relationship between religious faith and forgiveness in a sample (n = 196) of college students. Students were asked to complete the Heartland Forgiveness Scale and the Santa Clara Strength of Religious Faith Questionnaire. Analyses of scores on both measures revealed a positive, significant correlation between these constructs, suggesting that there is a meaningful relationship between religious faith and the tendency to forgive. Implications and directions for further research are discussed

Study of aluminoborane compound AlB_4H_(11) for hydrogen storage

Aluminoborane compounds AlB_4H_(11), AlB_5H_(12), and AlB_6H_(13) were reported by Himpsl and Bond in 1981, but they have eluded the attention of the worldwide hydrogen storage research community for more than a quarter of a century. These aluminoborane compounds have very attractive properties for hydrogen storage: high hydrogen capacity (i.e., 13.5, 12.9, and 12.4 wt % H, respectively) and attractive hydrogen desorption temperature (i.e., AlB_4H_(11) decomposes at ~125 °C). We have synthesized AlB_4H_(11) and studied its thermal desorption behavior using temperature-programmed desorption with mass spectrometry, gas volumetric (Sieverts) measurement, infrared (IR) spectroscopy, and solid state nuclear magnetic resonance (NMR). Rehydrogenation of hydrogen-desorbed products was performed and encouraging evidence of at least partial reversibility for hydrogenation at relatively mild conditions is observed. Our chemical analysis indicates that the formula for the compound is closer to AlB_4H_(12) than AlB_4H_(11)
