An Analysis of the Sixth Government Report on the Costs and Benefits of Federal Regulations
No full textAlso of interest by Hahn and Litan, "A Review of the Office of Management and Budget's Draft Guidelines for Conducting Regulatory Analyses". This paper critically reviews the draft of the Office of Management and Budget's sixth report on the benefits and costs of federal regulation. According to Robert W. Hahn and Robert E. Litan, the draft report represents an improvement over previous reports in some ways. While there has been progress, they say, some useful innovations from last year are not included in this draft. Mr. Hahn and Mr. Litan claim that there is room for significant improvement in this draft report. They offer five recommendations, one for Congress and four for OMB, that would help hold lawmakers more accountable for the regulations they produce. These recommendations focus on getting the regulatory agencies to produce better analysis, making that analysis more transparent and readily available, and making the regulatory process itself more transparent The authors recommend that OMB include a scorecard that summarizes the extent to which regulatory analyses comply with OMB's guidelines for regulatory analysis; provide information on regulations addressing terrorist threats; summarize useful information on a number of OMB's regulatory oversight activities, including return letters, prompt letters, turnaround time, and regulations and programs recommended for improvement or reform; and ask independent agencies to provide annual assessments of the costs and benefits of their economically significant regulations. Mr. Hahn and Mr. Litan also suggest that Congress require agencies to comply with OMB's information quality guidelines and guidelines for regulatory analysis.
Asymptotic iteration method for solving Hahn difference equations
No full textHahn’s difference operator Dq;wf(x)=(f(qx + w) – f(x))/((q – 1)x + w), q ∈ (0, 1), w > 0,
x = w/(1 – q) is used to unify the recently established difference and q-asymptotic
iteration methods (DAIM, qAIM). The technique is applied to solve the second-order
linear Hahn difference equations. The necessary and sufficient conditions for
polynomial solutions are derived and examined for the (q;w)-hypergeometric
equation.Natural Sciences and Engineering Research Council of CanadaCanadian Network for Research and Innovation in Machining Technolog
Pavetta trichardtensis var. jabulanii N. Hahn 2022, var. nov.
No full textPavetta trichardtensis var. jabulanii N. Hahn, var. nov. (Fig. 1–3) Type:— SOUTH AFRICA. Limpopo: Hanglip, 6 December 2019, N . Hahn 3129 (holotype ZPB!; isotypes PRE!, PRU!) Diagnosis:— Pavetta trichardtensis var. jabulanii is easily distinguished from the typical variety by its glabrous, shiny dark green leaves with sunken bacterial nodules above and glabrous calyx opposed to pubescent thinly textured leaves with bacterial nodules not prominent above and pubescent calyx (Fig. 2). In addition, var. jabulanii has on average smaller leaves (1.8–)3.5–6.8(–8.7) × (0.9–)1.7–2.9(–3.5) cm and petioles (0.3–)0.3–0.9(–1.4) cm long opposed to (2.6–)4.4–8.3(–8.9) × (1.4–)1.9–3.8(–5.3) cm and petioles (0.4–)0.6–1.2(–1.5) cm long for var. trichardtensis. Distribution:—Soutpansberg, Blouberg and possibly Houtbosch [Woodbush] (Fig. 1). The specimen, Houtbosch, Rehmann 6016 (K) cited under the description of P. zoutpansbergensis (Bremekamp 1934) was not examined. Rehmann 6016 is presently the only specimen of P. trichardtensis var. jabulanii recorded south of the Soutpansberg and Blouberg (Fig. 1). Conservation status:— Least Concern (LC). Pavetta trichardtensis var. jabulanii encompasses an EOO of approximately 8891 km 2 and an AOO at a 2 km cell width of 88 km 2 or AOO at a 5 km cell width of 525 km 2. This variant was possibly collected south of the Soutpansberg in 1875. Even though var. jabulanii EOO and AOO would fall under the Vulnerable category, the Soutpansberg and Blouberg communities seem to be quite stable and therefore do not fulfil any of the additional criteria for such listing. This variety does not qualify for any of the threatened categories and is therefore assigned a conservation status of Least Concern. Eponymy:—I have the honour of dedicating the specific epithet to Jabulani Linden, long standing friend and naturalist par excellence who has assisted and collaborated with me over many years to the conservation and natural history of the Soutpansberg. Jabulani is a fitting epitaph which has its origin from the isiZulu word meaning “rejoice” as this is a joyous occasion, finally having resolved the identity of the glabrous variant of Pavetta trichardtensis.

Government Analysis of the Benefits and Costs of Regulation
No full textRecently, Congress has shown a greater interest in assessing the economic impact of regulation. The interest is driven in part by estimates that federal regulation cost several hundred billion dollars annually. In 1996, Congress required the director of the Office of Management and Budget to provide estimates of the total annual benefits and costs of all federal regulatory programs and estimates of the benefits and costs of individual regulations. This essay reviews the increasing use of economic analysis in regulatory decision making, critically assesses the first OMB report, and considers how the use of economic analysis can help inform regulatory decision making. It argues that policy makers need to address a growing body of evidence that casts doubt on the effectiveness and efficiency of much regulation.Regulatory Reform
Interview with Herbert L. Hahn
No full textAn interview in four sessions, January 1981, with Pasadena attorney Herbert L. Hahn, a member of Caltech’s Board of Trustees from 1955 through 1969, and a Life Trustee thereafter. He discusses the early history of Caltech at the turn of the 20th century—originally Throop Polytechnic Institute, then Throop College of Technology—as well as the capitalists and entrepreneurs who supported it financially at that time.
Describes his early associations and friendships with numerous Caltech trustees and benefactors as an attorney, and how he eventually became a Caltech Associate and later a trustee. He offers recollections of, among others, Robert Andrews Millikan, William Bennett Munro, Royal W. Sorensen, Arnold Beckman, Keith Spalding, Archibald Young, Scott Brown, Albert Ruddock, Philip Fogg, Edward Valentine, Henry Dreyfuss, and Thomas J. Watson Jr., detailing their various contributions to Caltech and to the Pasadena community
