“Serials at Warp Speed: Navigating Transitions,” the 2007 North Carolina Serials Conference

Abstract

Reports on four major serials conferences, the 2007 North Carolina Serials Conference, the 2007 meeting of the Ohio Valley Group of Technical Services Librarians, the Canadian Library Association’s 2007 Pre-Conference, and the 2007 North American Serials Interest Group Conference.     

Leaning into Browser Extensions

abstract

An array of browser extensions has been developed to help researchers locate full-text content, whether that full text is available in an institutional repository, on a publishers site, or in an open access journal. Examples of such browser extensions include Unpaywall, Kopernio, EZproxy tools, and Lean Library. This Balance Point column focuses on the growth of browser extensions, the need they are filling, and their adoption by libraries. Particular attention is paid to the Lean Library browser extension and the services offered by Lean Library. Drawing on the literature and interviews with librarians in the field, the advantages and disadvantages of browser extensions are addressed, as well as security concerns.     

IFLA Library Reference Model,RDA, and Serials in a Nutshell

Abstract

IFLA Library Reference Model (IFLA LRM) represents the consolidation of Functional Requirements for Bibliographic Records (FRBR) and the two other conceptual models of the Functional Requirements (FR) family, the Functional Requirements for Authority Data (FRAD) and the Functional Requirements for Subject Authority Data (FRSAD). IFLA LRM includes a specific section (5.8) devoted to serials. The RDA Steering Committee adopted IFLA LRM as the conceptual model for the development of RDA in November 2016. The 3R (RDA Toolkit Restructure and Redesign) Project’s purpose is partly to make RDA compatible with the IFLA LRM. A beta version of the English-language content of the RDA Toolkit, which incorporates the IFLA LRM, was released in June 2018. This column explores, in lay terms, serials in relation to the IFLA LRM and the RDA Toolkit Restructure and Redesign (3R) Project. The beta version of the restructured and redesigned RDA Toolkit introduces several new concepts relating to serials.     

Determining Process Death Based on Censored Activity Data

This article addresses the problem of estimating the time of apparent death in a binary stochastic process. We show that, when only censored data are available, a fitted logistic regression model may estimate the time of death incorrectly. We improve this estimation by utilizing discrete-event simulation to produce simulated complete time series data. The proposed methodology may be applied to situations where time of death cannot be formally determined and has to be estimated based on prolonged inactivity. As an illustration, we use observed monthly activity patterns from 300 real Open Source Software development projects sampled from Sourceforge.net.

论公开审判与保守审判工作秘密的界限及关系

由于现行法律法规对审判公开与保守审判工作秘密没有明确的界定,致使中国在加入WTO后,人民法院依法进行的司法审判活动,受到了国际条约的挑战。因此,现今的法院工作应当秉着审判公务信息公开原则与保守审判工作秘密原则,把握好公开与保密的关系,来切实贯彻国际透明度原则,以实现司法公正。     

On the Evolution and Asymptotic Analysis of Open Markov Populations: Application to Consumption Credit

In this paper, we study, by means of randomized sampling, the long-run stability of some open Markov population fed with time-dependent Poisson inputs. We show that state probabilities within transient states converge—even when the overall expected population dimension increases without bound—under general conditions on the transition matrix and input intensities.

Following the convergence results, we obtain ML estimators for a particular sequence of input intensities, where the sequence of new arrivals is modeled by a sigmoidal function. These estimators allow for the forecast, by confidence intervals, of the evolution of the relative population structure in the transient states.

Applying these results to the study of a consumption credit portfolio, we estimate the implicit default rate.     

刑事庭审旁听制度研究

旁听制度作为刑事审判公开制度中的一个必要方面,对于整个刑事审判制度具有重要意义,但是无论在理论上或是司法实践中旁听制度都未能引起足够的重视。通过对我国目前旁听制度存在问题进行分析,找到症结之所在,从认识上进行一定的转变,并且给予旁听以更完善的保障措施,才能在此基础上不断推进旁听制度的完善。     

Document Delivery as a Supplement or Replacement for Serial Subscriptions

Abstract

Increasing serials costs and shrinking budgets present challenges for academic libraries to continue providing sufficient access to scholarly articles. Rapid document delivery services can serve as an effective means to fill the gap caused by serials cancellations. This column examines several of the existing document delivery service providers and addresses issues involved in their implementation.
