The Matthew effect in economics reconsidered

We apply the test of Ijiri and Simon (1974) to a large data set of authors in economics. This test has been used by Tol, 2009, Tol, 2013a to identify a (within-author) Matthew effect for authors based on citations. We show that the test is quite sensitive to its underlying assumptions and identifies too often a potential Matthew effect. We propose an alternative test based on the pure form of Gibrat's law. It states that stochastic proportionate citation growth, i.e. independent of its size, leads to a lognormal distribution. By using a one-sided Kolmogorov–Smirnov test we test for deviations from the lognormal distribution which we interpret as an indication of the Matthew effect. Using our large data set we also explore potential empirical characteristics of economists with a Matthew effect.     

纸张无损检测法在档案图书保护中的应用

纸张在保护和管理过程中需了解纸张保存现状和保存寿命。由于纸张检测方法大多要毁损纸张,因此,实际工作中很难开展档案图书纸张性能的检测和寿命的预测。本文介绍了目前国内外开展的纸张无损检测方法,分析各检测方法的优缺点和具体应用途径,通过纸张无损检测,来判断纸张保存现状,估计纸张的寿命,这对于降低纸张性能的下降速度,提高保护水平,改善保管环境有一定的指导作用。     

Pollutants in the Museum Environment - Practical Strategies for Problem Solving in Design,Exhibition and Storage

Abstract

The Oddy test is an 'accelerated' corrosion test employed by museums to evaluate the suitability of materials proposed for use in display and storage cases, The standard Oddy test requires a 28-day test period, and the results are assessed by visual observation. This paper describes an improved test method, which could reduce the length of the test period by half The improved method uses metal films as substitutes for the traditional metal coupons posing as 'surrogate art object', The new test results are then evaluated by computer with digital image processing for more objective selection of less corrosive materials.

Accessibility of Psychology and Education Test Kits

Abstract

In the mid-1980s, education and social science librarians began to gather information about libraries' management of test collections. This article looks at the circulation loan patterns represented in past research and compares it to results of a survey conducted by the authors. The survey also determined whether libraries are modifying their policies to provide broader access to psycho-educational test kits for distance education students. Circulation loan patterns reported in past studies are compared with current survey results to determine whether libraries modify their policies to improve access to psycho-educational test kits for online and distance education students. The survey looks at ownership and responsibility of test kits, authorizing access and in-house and unrestricted circulation policies.     

高校学生的信息素养测试实验——以中山大学为例

文章采用信息素养评价方法中的测试法对中山大学的学生进行抽样调研。数据分析的结果认为大部分学生都能达到及格水平,跟以往他人采用不同方法的调研结果明显不同。认为测试法的调研可作为其他调研方法的补充,建议今后要加强测试法的研究与应用。

Refinements Introduced in the Oddy Test Methodology

The ‘Oddy test’ is an accelerated corrosion test introduced in the 1970s at the British Museum to identify materials likely to emit volatile substances that could harm museum artefacts. It is carried out in many museums all around the world, but not always using the same methodology, which makes it difficult to compare and share test results between institutions. Refinements to the Oddy test methodology have been implemented at the British Museum over the last decade and the aim of this paper is to present these and promote consistency across institutions. The modifications introduced concern the method used to wash the glassware, the preparation of the metal coupons, and standard methods for preparing samples of liquid coatings, adhesives, and adhesive tapes. Finally, conducting Oddy tests is time consuming and measures employed at the British Museum to reduce the number of materials to be tested and streamline testing are described.

Do published search filters to identify diagnostic test accuracy studies perform adequately?

OBJECTIVES: To assess the performance of published search filters in finding diagnostic test accuracy studies. METHODS: Diagnostic test accuracy search filters were identified by searching medline, our own files and by requesting unpublished filters from colleagues. We applied the filters to a case study review of diagnostic test accuracy studies for urinary tract infections (UTI) in young children. The included studies with records in medline formed the gold standard. The performance of the filters in finding those gold standard records was assessed. RESULTS: We identified twenty-three diagnostic test accuracy search filters for use with medline. The case study systematic review of UTI included 179 studies of diagnostic test accuracy, of which 160 were available in medline. The filters showed a wide range of sensitivities (range: 20.6% to 86.9%) and precision (range: 1% to 9.4%). CONCLUSIONS: Our results broadly support those reported in two other studies. The search filters tested do not offer an adequate trade-off between sensitivity and precision to be used to identify studies for systematic reviews. However, there are methods available to explore whether search filters are viable based on an objective statistical analysis of the text and indexing used in records.     

Selected Test Collections in the United States:

Although a literature search yields much data on validity, reliability and construction of educational and psychological tests, little information on test collection management in libraries is available. The University of Illinois at Urbana-Champaign initiated a survey of selected test collections in order to verify that their practices conformed with those of other institutions. An attempt was also made to rank collections and compare staff and budget allocations. The fact that two other institutions were found during the distribution and compilation of the survey to be engaged in a similar activity indicates that there is currently great interest in the management of test collections in libraries.
