In the two years before President Franklin D. Roosevelt signed into being the Social Security Act, the government succeeded in putting many citizens to work through other New Deal programs. Already in July, the American Alliance of Museums (AAM), disseminated a press release cum prophecy detailing that "one out of every three museums may shutter forever as funding sources and financial reserves run dry. Without near-term assistance from governments and private donors, hundreds of directors reported their museums may not survive the financial crisis brought on by the pandemic.".

This article describes the work of the Circle of Courage, a cross-cultural group committed to improving the cultural competence of organizations providing services to Aboriginal populations in a midsized city in Canada. Rather than concentrating on individuals' cultural competence, the Circle targets mainstream organizations. Many of its activities, therefore, require organizations to examine themselves and make systemic changes. Providing support to Aboriginal staff of mainstream organizations is a significant element of the Circle's initiatives. After an analysis of cultural proficiency—particularly at the organizational and systemic levels—the history of the Circle, its internal functioning, and its specific activities are described. The impact of the Circle's attempts to make systemic change is summarized. [ABSTRACT FROM AUTHOR]

This article examines a retrospective of Robert Ryman's contemporary artwork which was displayed at the Museum of Modern Art in New York in 1993. Ryman refuses teleologies and has never been productively associated with any artistic movement. Ryman's nonrepresentational paintings do not use paint illusionistically. Nor do they use color mimetically, metaphorically or emotively. Ryman also insists that his paintings are neither monochromatic nor abstract.

Confidence intervals for discrete distributions are often evaluated only by coverage and expected length. We discuss two additional criteria, p-confidence and p-bias. The choice of these criteria is motivated by the interpretation of a confidence interval as being the set of parameter values not rejected by a hypothesis test. Using these additional criteria we compare a number of equal-tailed confidence intervals for the binomial distribution. It is shown that methods that produce superior intervals, as measured by coverage and length, need not perform well in terms of p-confidence and p-bias. Cox's measuring device example is discussed to motivate the need for criteria beyond coverage and length. [ABSTRACT FROM AUTHOR]

Two resampling procedures, the bootstrap (BS) and the conditional confidence interval (CCI), are compared with the standard t-interval for the slope parameter in simple linear regression with an error term that is not necessarily normal. The type of bootstrap confidence intervals computed are the widely used bias-corrected and accelerated (BC[SUBa]) intervals. The CCIs are found by an efficient method for inverting permutation tests. Normal, highly skewed, and heavy-tailed error distributions are considered. While the CCI and BC[SUBa] intervals have similar asymptotic properties, for a moderate number of cases, the confidence intervals obtained from the CCI and BC[SUBa] behave di8erently in terms of accuracy, power, length, and correctness. Across all conditions, the CCI is the most accurate interval and has very good power. The t-intervals are also very accurate across most of the conditions we studied, and have coverage closer to the nominal value than the BC[SUBa] intervals. [ABSTRACT FROM AUTHOR]

Several new results are presented for a class of univariate distributions for which the maximum likelihood estimate of the population mean is the sample mean. It is shown that the convolution of any two such distributions also belongs to this class of functions. It is also shown that the marginal distribution for the sample mean captures all of the Fisher information for the population mean contained in the full distribution. Parameters orthogonal to the mean are found for special cases of these distributions. If the distribution is conditioned on the sample mean, the conditional distribution depends on the parameters only through parameters orthogonal to the mean. [ABSTRACT FROM AUTHOR]
