A course in constructing effective displays of data for pharmaceutical research personnel

Interpreting data and communicating effectively through graphs and tables are requisite skills for statisticians and non‐statisticians in the pharmaceutical industry. However, the quality of visual displays of data in the medical and pharmaceutical literature and at scientific conferences is severely lacking. We describe an interactive, workshop‐driven, 2‐day short course that we constructed for pharmaceutical research personnel to learn these skills. The examples in the course and the workshop datasets source from our professional experiences, the scientific literature, and the mass media. During the course, the participants are exposed to and gain hands‐on experience with the principles of visual and graphical perception, design, and construction of both graphic and tabular displays of quantitative and qualitative information. After completing the course, with a critical eye, the participants are able to construct, revise, critique, and interpret graphic and tabular displays according to an extensive set of guidelines.

Confession Magazines

Abstract

The results of this survey underscore the controversy surrounding the elimination of OCLC's Serials Control Subsystem. The survey evoked responses more numerous and fervent than I anticipated when the project began. As might be expected, those libraries that used the system more extensively and checked in the higher number of formats on SCS were most likely to describe the impact of SCS's elimination as serious. Most of the respondents expected that their immediate choice for a new serials control system would be permanent. As one respondent commented, “…librarians cannot afford to be switching serials control systems every few years.” Among libraries using the Serials Control Subsystem, approximately one-third chose to switch to OCLC's SC350, but no alternative serials system emerged as the second choice.     

Culinary Magazines

Abstract

Marvel Comics, along with rival DC Comics, is one of the two powerhouses of the comic book industry and has been for many decades. The company was founded in 1939 by pulp magazine publisher Martin Goodman. Goodman owned various publishing houses responsible for a variety of pulp titles, including Marvel Science Stories. In 1939, a colleague persuaded Goodman that comic books were the upcoming trend in periodical publishing, so Good-man launched a book called Marvel Comics. Issue no. 1 contained a story by Bill Everett about the Sub-Mariner, as well as the first appearance of the Human Torch. Both characters quickly became leading draws of the Golden Age of comics. Soon after, Goodman hired writer Joe Simon and artist Jack Kirby, who were to become giants in the industry. Simon and Kirby created Captain America, a character who remains a comics icon even today. In those early days, Goodman also hired another future legend: writer Stan Lee, who happened to be Good-man's nephew.

Goodman's comic company was known officially as Timely Comics, Inc., then later as Atlas Publishing. The firm did not change its name to Marvel until the early 1960s. Timely benefitted from the comics boom of the early 1940s, but interest in super-hero stories waned later in the decade. Atlas briefly revived its super-hero line-up in 1954, but the company spent most of the next decade publishing romance, western, horror, and humor comics.1 1.

Tabloids

Abstract

Comic books and libraries do not seem to get along, at least not in North American libraries. Aside from a few dozen specialized, noncirculating research collections, retrospective comic book holdings remain virtually unknown as a library resource.1 Browsing collections of current comic books are equally rare in public, school, and college libraries. In a 1984 article, comic book bibliographer Randall Scott observed, “In most communities, if you want to read or refer to a comic book, you have to buy it.” Librarian Doug Highsmith concurred, writing in 1992 that public libraries carrying the latest issues of popular comics titles are “still the exception rather than the rule.” Both statements remain fundamentally true today.     

Consistency of maximum likelihood estimators in a large class of deconvolution models

We consider the maximum likelihood estimator $\hat{F}_n$ of a distribution function in a class of deconvolution models where the known density of the noise variable is of bounded variation. This class of noise densities contains in particular bounded, decreasing densities. The estimator $\hat{F}_n$ is defined, characterized in terms of Fenchel optimality conditions and computed. Under appropriate conditions, various consistency results for $\hat{F}_n$ are derived, including uniform strong consistency.

Powers of Discrete Goodness-of-Fit Test Statistics for a Uniform Null Against a Selection of Alternative Distributions

The comparative powers of six discrete goodness-of-fit test statistics for a uniform null distribution against a variety of fully specified alternative distributions are discussed. The results suggest that the test statistics based on the empirical distribution function for ordinal data (Kolmogorov–Smirnov, Cramér–von Mises, and Anderson–Darling) are generally more powerful for trend alternative distributions. The test statistics for nominal (Pearson's chi-square and the nominal Kolmogorov–Smirnov) and circular data (Watson's test statistic) are shown to be generally more powerful for the investigated triangular (∨), flat (or platykurtic type), sharp (or leptokurtic type), and bimodal alternative distributions.     

Classes of diffusion-type processes with a sufficient reduction

Classes of processes of the diffusion type permitting a sufficient data reduction are derived. None of these classes are exponential families in the usual sense. For one type of such classes the sufficient statistic equals that of a curved exponential family of diffusion-type processes. For a second type the last observation is sufficient. In particular cases both types of classes are defined by means of a RICCATI equation
