Redrawing the line: challenging the publisher-library relationship

Within the scholarly ecosystem academia, libraries and publishers have evolved together over the last 150 years into an established order of publishing and dissemination. Massive changes in technology,disruptive publishing models and the globalisation of education have meant that this accepted order is being significantly challenged. This article outlines how the University of Sussex Library is working with SAGE publishing to develop a trusted relationship and an alternative space (both physical and metaphorical) for conversations and collaboration

Imperialism and accountability in corporate law: the limitations of incorporation law as a regulatory mechanism

This article discusses the limitations of the law incorporating a corporation (‘incorporation law’) as a control or governance mechanism in a world where it is increasingly difficult to prevent corporations choosing the incorporation law which suits them best. It uses as an example of the globalising pressures in this field three important cases on the right of establishment in the European Union

A Micro-Computed Tomographic Assessment of Dentin Removal Following Ultrasonically Activated Irrigation Comparing Stainless Steel and Nickel-Titanium Tips

Introduction: Ultrasonic irrigation is performed to disinfect and debride the canal space, yet little is known about the influence of ultrasonic tip selection and its impact on the surrounding structural components. The aim of this study was to quantitatively evaluate the amount of dentin removed following ultrasonic irrigation using the EndoUltra™ ultrasonic device. We compared this to a Satelec® Aceton® P5 Newtron® XS LED ultrasonic unit, commonly used in our postgraduate clinic at the Medical University of South Carolina. Methods: Thirty mandibular premolars were standardized in length and instrumented to a size 35/04 taper. The teeth were then randomly divided into two groups (n = 15). Group A: 20/02 NSK Varios SS U files; Group B: 15/02 EndoUltra™ NiTi tips. Teeth were scanned following instrumentation using a micro-computed tomographic (micro-CT) device at an isotropic resolution of 16 μm. Ultrasonic irrigation was completed for both Groups using 6% sodium hypochlorite (NaOCl), 17% EDTA and 2% CHX, with 0.9% saline rinse following each irrigating solution. After final irrigation, the teeth were scanned a second time. Three-dimensional models were created to determine volumetric changes in dentin from pre- and post-irrigation scan comparisons. Statistical analysis of data was performed with a Wilcoxon signed-rank test, with significance set at P \u3c.05. Results: Removal of dentin was observed within both Groups. A statistically significant difference (P \u3c.01) in the amount of dentin removed between Group A (Satelec® using a 20/02 SS U file) and Group B (EndoUltra™ 15/02 NiTi tip) following ultrasonic irrigation was observed. Conclusions: Both groups exhibited dentin removal following ultrasonic activation. The EndoUltra™ manufacturer’s claim that their activator tips do not engage or remove tooth structure was disproved

Why we need to find time for digital humanities: presenting a new partnership model at the University of Sussex

Recognizing that academic libraries should develop and nurture strong, mutually beneficial relationships with researchers in digital humanities, the authors believe it is strategically important to invest time and resources exploring ideas and partnering with academic colleagues on projects. This approach can provide many unforeseen benefits to both the Library service and to the workforce. The article is based on our experience as Core Associates of the Sussex Humanities Lab at the University of Sussex. It outlines the impact this collaboration has had, including influencing working practices and culture within the Library, involvement in research bids, informing the development of new services, and addressing library questions using digital humanities methods. Most importantly, it exemplifies a new model of the librarian as equal partner in the research process

Working with public libraries to enhance access to quality-assured health information for the lay public: Healthinfo4u: British Library Co-operation and Partnership Programme no.6: final report

This study provides the results of a 22-month project to research whether web technology can be used to provide the lay public with quality-assured, evidence-based journal literature previously only available to health care professionals. The study documents the development of the demonstrator product and the results of its trial and evaluation, using action research methodologies, in selected public libraries and health information points in the UK. The literature review provides the context for the development of the provision of health information for the lay public and considers the issues surrounding the provision of e-journals. The study also provides an assessment of the potential requirements for a viable future web-based resource to provide consumers with the full text of quality-assured health information selected from journals used by health care professionals

Two-path subsets: Efficient counting and applications to performability analysis

The problem of computing performability probabilities in stochastic PERT and flow networks is studied when the network is minimally designed to withstand any two component failures. Polynomial-time algorithms to compute performability when the network is planar - the nonplanar versions being NP-hard - solve related two-path subset problems. Given an acyclic graph with weights on the arcs, the algorithms compute the total weight of all subsets of arcs that are contained in (1) two source-sink paths, or (2) two are-disjoint source-sink paths. A polynomial algorithm is given for (1), and for (2) in the case where the graph is a source-sink planar k-flow graph, that is, cdge-minimal with respect to supporting k units of flow

NESTING ECOLOGY OF SANDHILL CRANES AT GRAYS LAKE, IDAHO

We examined the nesting ecology of greater sandhill cranes (Grus canadensis tabida) at Grays Lake, Idaho during 1997-99 to detennine the effects of nest-site characteristics and land use on crane nest success. These are preliminary results from 3 years of a 4-year study. Crane nests were located in portions of the Grays Lake basin from early May through late June each year (n = 131 in 1997; n = 131 in 1998; n = 143 in 1999). Apparent nest success varied among years (54% in 1997, 71% in 1998, and 53% in 1999; overall average of 59%). We estimate that 10% of nests found in 1999 were renests. Most crane nests were located in baltic rush/spikerush (Juncus balticus/Eleocharis sp.; 46% of nests), semi-wet meadow (19%), and bulrush/cattail (Scirpus sp./Typha sp.; 19%) plant communities; 62% of nests during early May were in:;; 12 cm of water. As indicated by plant community, water depths at nests, and nest isolation rankings, nest success tended to be higher where nests were in relatively deep water (ca. \u3e40 em) and were relatively isolated from access by mammalian predators. Nest success rates during 1997-99 were lower than those recorded in 1950-51 (90%, n = 107; Steel 1952) and 1970-71 (78%, n = 308; Drewien 1973). A variety offactors likely contribute to lower nest success, including changing predator communities over the past 30-40 years. Differences among years in our study may be affected by changing availability of alternate prey. Small mammal populations and crane nest success were the highest in 1998. Water-level management, relating to cranes and other waterbird populations, plant communities, and ecosystem function, is an emerging issue for land managers in the Grays Lake basin
