    Whose Rebellion? Reformed Resistance Theory in America: Part I

    Full text link
    Students of the American Founding routinely assert that America\u27s civic leaders were influenced by secular Lockean political ideas, especially on the question of resistance to tyrannical authority. Yet virtually every political idea usually attributed to John Locke was alive and well among Reformed political thinkers decades before Locke wrote the Second Treatise. In this two-part essay, we trace just one element of the Reformed political tradition: the question of who may actively and justly resist a tyrant. We focus on the American experience but begin our discussion by considering the early Reformers

    Whose Rebellion? Reformed Resistance Theory in America: Part II

    Students of the American Founding routinely assert that America\u27s civic leaders were influenced by secular Lockean political ideas, especially on the question of resistance to tyrannical authority. In the first part of this series, we showed that virtually all Reformed writers, from Calvin to the end of the Glorious Revolution, agreed that tyrants could be actively resisted. The only debated question was who could resist them. In this essay, we contend that the Reformed approach to active resistance had an important influence on how America\u27s Founders responded to perceived tyrannical actions by Parliament and the Crown

    Results and comparison of Hall and DW duct experiments

    Experimental data from recent tests of a 45 deg diagonal wall duct are presented and compared with the results of a similar Hall duct. It is shown that while the peak power density of the two devices is approximately equal that the diagonal wall duct produces greater total power output due to its ability to better utilize the available magnetic field

    Portfolio return autocorrelation and non-synchronous trading in UK equities

    Although infrequent trading in equity stocks is more prevalent in the United Kingdom (and other non-United States countries), we find that it is proportionally more important in explaining the degree of serial correlation in stock returns in the US than in the UK, in contrast to much of the existing literature.We show that infrequent trading cannot explain more than a small proportion of the serial correlation observed in monthly UK stock returns and hence, other explanations for return predictability must be sought. Many studies have shown that stock market returns in the UK and other international markets are substantially and significantly serially correlated. The success of an investment strategy that is based on the apparent predictability of returns depends on whether the serial correlation is truly random and period specific or due to time varying risk premia or to market microstructure effects. A frequently noted explanation for this serial correlation is market thinness or, more precisely, the infrequency with which a substantial number of UK stocks are traded. Non-synchronous trading results in a measurement error in the observed data for returns on individual stocks, portfolios and market indices. This measurement error generates serial correlation in the observed returns. Here, we assess the extent to which the observed serial correlation in returns can be explained by equity non-trading behaviour. This will reveal whether there is any residual serial correlation left to be explained by alternative sources. We find that, whilst a proportion of the serial correlation in the returns of portfolios of low value stocks can be explained by non-trading, much of it still remains unexplained.

    Assessing Displacement and Magnitude Effects on Relative Preferences of Edible and High-tech Leisure Items

    Previous studies have shown when edible and leisure items (e.g., toys) are combined in multiple-stimulus-without-replacement (MSWO) preference assessments, edible items are often more preferred than leisure items by individuals with developmental disabilities (Bojak & Carr, 1999; DeLeon et al., 1997; Fahmie et al., 2015). However, how the inclusion of high-tech items (e.g., iPads ®, tablets, computers) affects preferences when compared to edible items is limited in this body of research. More recently, Conine and Vollmer (2019) demonstrated high-tech items might displace edible items; due to the recent influx of high-tech tangible items used as reinforcers in clinical settings, such as iPads, additional research is warranted. In the current evaluation, we compared the preferences for edible items and high-tech items in an assessment to determine if a displacement effect exists. Next, we manipulated the magnitude of both stimulus classes to assess how greater magnitude influences preference. Results showed high-tech leisure items were more preferred over edible items for 2 out of 3 subjects during the combined MSWO. However, regardless of the magnitude across stimuli, edible items were more likely to be selected during the magnitude assessment in the current study. Implications of the findings as well as future research ideas will be discussed in detail

    Complete graphs whose topological symmetry groups are polyhedral

    We determine for which mm, the complete graph KmK_m has an embedding in S3S^3 whose topological symmetry group is isomorphic to one of the polyhedral groups: A4A_4, A5A_5, or S4S_4.Comment: 27 pages, 12 figures; v.2 and v.3 include minor revision

    A novel synthetic chemistry approach to linkage-specific ubiquitin conjugation.

    Get PDF
    Ubiquitination is of great importance as the post-translational modification of proteins with ubiquitin, or ubiquitin chains, facilitates a number of vital cellular processes. Herein we present a facile method of preparing various ubiquitin conjugates under mild conditions using michael acceptors based on dibromo-maleimides and dibromo-pyridazinediones
