    Paintings and their implicit presuppositions : a preliminary report

    In a series of earlier papers (Social Science Working Papers 350, 355. 357) we have studied the ways in which differences in "implicit presupposi tions" (i. e •• differences in world views) cause scientists and historians to reach differing conclusions from a consideration of the same evidence. In this paper we show that paintings are characterized by implicit presuppositions similar to those that characterize the written materials -- essays, letters, scientific papers -- we have already studied

    Paintings and their implicit presuppositions: High Renaissance and Mannerism

    Get PDF
    All art historians who are interested in questions of "styles" or "schools" agree in identifying a High Renaissance school of Italian painting. There is, however, a disagreement, which has seemed nonterminating, regarding Mannerism: Is it another distinct school or is it merely a late development of the Renaissance school? We believe that this disagreement can be terminated by distinguishing questions of fact about paintings from questions about the definitions of schools. To this end we have had two representative subsets of paintings--one earlier, one later--rated on four of the dimensions of implicit presuppositions that we have introduced in other Working Papers. When the paintings are scaled in this way a very distinct profile emerges for the earlier, or Renaissance, paintings. In contrast, the later, or Mannerist, paintings are so heterogeneous that we conclude that they are best described as deviations from the Renaissance profile, rather than a separate school. These results are not unimportant--at least for art historians. But they are more important methodologically inasmuch as the procedures applied here can be used in classifying and distinguishing from one another all kind of cultural products

    Long-term evolution of highly alkaline steel slag drainage waters

    © 2015, Springer International Publishing Switzerland. The disposal of slag generated by the steel industry can have negative consequences upon the surrounding aquatic environment by the generation of high pH waters, leaching of potentially problematic trace metals, and rapid rates of calcite precipitation which smother benthic habitats. A 36-year dataset was collated from the long-term ambient monitoring of physicochemical parameters and elemental concentrations of samples from two steel slag leachate-affected watercourses in northern England. Waters were typified by elevated pH ( > 10), high alkalinity, and were rich in dissolved metals (e.g. calcium (Ca), aluminium (Al), and zinc (Zn)). Long-term trend analysis was performed upon pH, alkalinity, and Ca concentration which, in addition to Ca flux calculations, were used to highlight the longevity of pollution arising as a result of the dumping and subsequent leaching of steel slags. Declines in calcium and alkalinity have been modest over the monitoring period and not accompanied by significant declines in water pH. If the monotonic trends of decline in alkalinity and calcium continue in the largest of the receiving streams, it will be in the region of 50–80 years before calcite precipitation would be expected to be close to baseline levels, where ecological impacts would be negligible

    The potential use of exhausted open pit mine voids as sinks for atmospheric CO2: insights from natural reedbeds and mine water treatment wetlands

    Get PDF
    Abandoned surface mine voids are often left to flood, forming pit lakes. Drawing simple but important lessons from experiences with compost-based passive remediation systems for acidic mine waters, an alternative end-use for open pit mine voids is proposed: gradual infilling with organic material, which can serve as a long-term sink for atmospheric CO2, whilst ameliorating or eventually eliminating sustained evaporative water loss and acidic water pollution. Key to the success of this approach is the suppression of methane release from organic sediments flooded with sulfate-rich mine waters: the presence of modest amounts of sulfate (which is typically abundant in mine waters) inhibits the activity of methanogenic bacteria. This explains why gas release studies of mine water treatment wetlands never report methane emissions; CO2 is the only greenhouse gas emitted, and this is clearly not at levels sufficient to undo the benefits of wetlands as net CO2 sinks. While the compete infilling of open pits with organic sediments might take a very long time, only minimal maintenance would be needed, and if carbon trading markets finally mature, a steady income stream could be obtained to cover the costs, thus extending the economic life of the mine site far beyond cessation of mining

    From Lord Coke to Internet Privacy: The Past, Present, and Future of Electronic Contracting

    Get PDF
    Contract law is applied countless times every day, in every manner of transaction large or small. Rarely are those transactions reflected in an agreement produced by a lawyer; quite the contrary, almost all contracts are concluded by persons with no legal training and often by persons who do not have a great deal of education. In recent years, moreover, technological advances have provided novel methods of creating contracts. Those facts present practitioners of contract law with an interesting conundrum: The law must be sensible and stable if parties are to have confidence in the security of their arrangements; but contract law also must be able to handle changing social and economic circumstances, changes that occur at an ever-increasing speed. Contract law, originally designed to handle agreements reached by persons familiar with one another, evolved over time to solve the problems posed by contract formation that was done at a distance — that is, contract law had developed to handle first paper, then telegraphic, and finally telephonic communications. It has handled those changes very well. In the 1990s, however, things began to change. The rise in computer use by individuals coupled with the advent of the World Wide Web gave rise to two parallel developments, both of which challenged the law of contract formation. Increased computer use created a demand for software programs designed for the consumer market, and those programs were commonly transferred to users by way of standard-form licenses that were packaged with the software and thus unavailable before the consumer paid for the software. Also, parties in large numbers began to use electronic means — the computer — to enter into bargained-for relationships. The turn of the millennium brought two electronic contracting statutes, the Electronic Signatures in Global and National Commerce Act (“E-Sign”) and the Uniform Electronic Transactions Act (“UETA”), which removed any doubts that contracts entered into electronically could satisfy the Statute of Frauds. Encouraged by the certainty given by those statutes, internet businesses started offering contract terms on their websites, asking customers to consent to terms by clicking an icon, or by not seeking express assent at all by presenting terms of use by hyperlink. The ease of presenting terms comprised of thousands of words by an internet hyperlink makes it easy for a vendor in its terms of use and terms of service to ask us to give up privacy rights and intellectual property rights. Modern communications technologies therefore make it easier for parties to engage in risky transactions. Nevertheless, we believe that, with few exceptions, the common law of contracts is sufficiently malleable to address the problems arising out of that behavior and where it is not, regulation of contract terms is appropriate. This Article examines those developments

    How and Why lslamophobia is tied to English Nationalism but not to Scottish Nationalism

    Muslim minorities throughout Europe are under threat of collateral damage from the Blair/Bush \u27War on Terror.\u27 In Scotland they also have to cope with the added possibility that Scottish nationalism might develop an \u27ethnic\u27 as well as a \u27civic\u27 dimension. But is Scottish nationalism part of the problem or part of the solution? Paradoxically, Muslims are under less pressure in Scotland than in England, despite Scotland\u27s move over recent decades--psychologically as well as institutionally--towards nationalism

    The Erosion of Rights: Declining Civil Rights Enforcement Under the Bush Administration

    Get PDF
    The erosion of civil rights across our nation over the past six years is the result of willful neglect and calculated design. The Bush administration continues to use the courts and the judicial appointment process to narrow civil rights protections and repeal remedies for legal redress while allowing the traditional tools of the executive branch for civil rights enforcement to wither and die. The resulting inequality of opportunity, deteriorating civil liberties, and rising religious and racial discrimination are sad commentaries on the priorities of the current administration
