21st‐century rights management: why does it matter and what is being done?
Authors: BIDE Mark , WISE Alicia 
Published: November 2009

ABSTRACT‘The answer to the machine is in the machine’ – but what is the answer? At the end of the first decade of the 21st century we are seeing an explosion of rights management issues, as well as the emergence of many products and services that may provide all – or at least some – of the solution for publishers. International standards are also in place. Strong intellectual property protection is the cornerstone of an orderly digital marketplace. That market is for content + rights. Are our rights management practices fit for purpose? In this paper we provide an overview of rights management in publishing at the start of the 21st century, a summary of what is at stake, and an overview of the challenges and opportunities that await publishers.
Whose metrics? Citation, usage and access metrics as scholarly information service
Authors: ARMBRUSTER Chris 
Published: November 2009

ABSTRACTAs the Internet has enhanced the collection and provision of citation, usage, and access metrics, the challenge lies neither in the technology nor the method, but in constructing databases that deliver services of value to the scholar. The question everybody should be asking is: what kind of metric information services would serve scholars? One example is given of the systems that might well help a postdoctoral researcher.
Paying for open access? Institutional funding streams and OA publication charges
Authors: PINFIELD Stephen 
Published: November 2009

ABSTRACTAn increasing number of research funders are introducing open access (OA) policies. At the same time, publishers are introducing OA publication options. Research institutions need to consider how to respond to these developments, including the possible introduction of institutionally co‐ordinated funds for payment of OA publication charges. This paper describes the international background to the issue of institutional OA funds and summarizes the current UK situation, presenting recently gathered data from UK institutions. It then reports on work carried out by the University of Nottingham to introduce and manage an institutional OA fund. Early usage data of the Nottingham fund are presented. The paper outlines lessons learned from the Nottingham experience, then goes on to suggest a number of ways in which institutions and other agencies can take developments forward.
What pharmaceutical libraries really want
Authors: NIELSEN Henning P. , VOGT Sven‐Olaf 
Published: November 2009

ABSTRACTThe multiplicity of publisher business models and the restrictions of digital rights management systems greatly hamper pharmaceutical companies in the prosecution of their work. We explore the variety of ‘pharma’ needs and the reasons for them. Much progress has been made but more needs to be done. The libraries seek only to satisfy their customer needs while complying with owners' rights.
Should editors influence journal impact factors?
Authors: KRELL Frank‐Thorsten 
Published: November 2009

ABSTRACTThe journal impact factor is widely used as a performance indicator for single authors (despite its unsuitably in this respect). Hence, authors are increasingly exercised if there is any sign that impact factors are being manipulated. Editors who ask authors to cite relevant papers from their own journal are accused of acting unethically. This is surprising because, besides publishers, authors are the primary beneficiaries of an increased impact factor of the journal in which they publish, and because the citation process is biased anyway. There is growing evidence that quality and relevance are not always the reasons for choosing references. Authors' biases and personal environments as well as strategic considerations are major factors. As long as an editor does not force authors to cite irrelevant papers from their own journal, I consider it as a matter of caretaking for the journal and its authors if an editor brings recent papers to the authors' attention. It would be unfair to authors and disloyal to the publisher if an editor did not try to increase the impact of his/her own journal.
Duration of clinical reactivity in cow's milk allergy is associated with levels of specific immunoglobulin G4 and immunoglobulin A antibodies to β‐lactoglobulin
Authors: Savilahti E. M. , Saarinen K. M. , Savilahti E. 
Published: December 2009

SummaryBackground
The development of tolerance in IgE‐mediated allergies has been associated with lower cow's milk (CM)‐specific IgE levels, increasing levels of specific IgG4 and, more contestably, IgA.Objective
We investigated whether specific antibody responses to CM proteins differ over time between patients who recovered from cow's milk allergy (CMA) by the age of 3 years and those who developed tolerance only after the age of 8 years.Methods
The study population comprised of 83 patients with IgE‐mediated CMA. They belonged to a cohort of 6209 healthy, full‐term infants followed prospectively for the emergence of CMA. Serum samples were available at diagnosis (median age 7 months), 1 year later (median 19 months) and at follow‐up (median 8.5 years). Age‐matched control subjects with no history of CMA (n=76) participated in the follow‐up. Serum levels of IgE antibodies to CM were measured using UniCAP. Levels of IgA, IgG1 and IgG4 antibodies to β‐lactoglobulin and α‐casein were measured using ELISA.Results
Patients with persistent CMA at the age of 8 years (n=18 at diagnosis, n=16 at later time‐points) had higher CM‐specific IgE levels at all three time‐points (P<0.001) compared with patients who became tolerant by 3 years (n=55 at diagnosis, n=54 a year later, n=40 at follow‐up). They had lower serum IgA levels to β‐lactoglobulin at diagnosis (P=0.01), and lower IgG4 levels to β‐lactoglobulin (P=0.04) and α‐casein (P=0.05) at follow‐up.Conclusion
High CM‐specific IgE levels predict the persistence of CMA. Development of tolerance is associated with elevated levels of β‐lactoglobulin‐specific serum IgA at the time of diagnosis, and later increasing specific IgG4 levels to β‐lactoglobulin and α‐casein.

Published: December 2009

SummaryWe describe a patient with previous solid-organ (testicular, oesophageal) and haematological (acute myeloid leukaemia) malignancies, in whom chronic cutaneous graft-versus-host disease was complicated by poromas and porokeratosis. Chemotherapy, total body irradiation, longstanding immunosuppression and ultraviolet radiation may all have played a part in the pathogenesis of the skin tumours.
Relationship of impairment induced by intracellular S‐adenosylhomocysteine accumulation with DNA methylation in human umbilical vein endothelial cells treated with 3‐deazaadenosine
Authors: Yu Xiaoping , Ling Wenhua , Mi Mantian 
Published: December 2009

SummaryThe aim of this study was to estimate the relationship of endothelial dysfunction induced by intracellular S‐adenosylhomocysteine (SAH) accumulation and DNA methylation in human umbilical vein endothelial cells (HUVEC). The isolated HUVEC were incubated with 3‐deazaadenosine (DZA) to induce experimental intracellular SAH accumulation. The impairment of HUVEC function was assessed by changes in morphology and proliferative ability. The expression of DNA methyltransferase‐1 (DNMT1) and the atherosclerosis related genes [oestrogen receptor‐alpha (ER‐α), extracellular superoxide dismutase (EC‐SOD) and monocyte chemoattractant protein‐1 (MCP‐1)] were analysed using quantitative real‐time PCR. Global DNA methylated status was measured using the cytosine extension assay. The methylated patterns of ER‐α, EC‐SOD and MCP‐1 genes were determined with methylation‐specific PCR. We found that DZA administration increased intracellular SAH levels progressively and simultaneously decreased Hcy content in medium. Moreover, the supplementation induced HUVEC apoptosis, inhibited proliferation ability and DNMT1 mRNA expression (P < 0.05) and furthermore reduced global DNA methylation status (P < 0.05). Correlation analysis showed the presence of a negative correlation between intracellular SAH concentration, proliferative ability, and expression of ER‐α, EC‐SOD, and DNMT1 (r = −0.89, −0.86, −0.92 and −0.88 respectively, P < 0.001); and a positive correlation with MCP‐1 expression and DNA [3H]‐dCTP incorporation (r = 0.89 and 0.93 respectively, P < 0.001). Our results showed that endothelial dysfunction induced by intracellular SAH accumulation is mediated by regulating the expression of atherosclerosis related genes in HUVEC, which is not related with gene promoter methylated patterns, but may be associated with altered global DNA hypomethylated status. These findings suggest that SAH can act as the potential molecular biological marker in the promotion of atherogenesis.
Asset allocation and age effects in retirement savings choices
Authors: Gerrans Paul , Clark‐Murphy Marilyn , Speelman Craig 
Published: December 2009

AbstractWe examine the asset allocation decisions of members of three large Australian retirement savings funds. Superannuation Guarantee legislation in 1992 made Australian employees compulsory investors by requiring employers to contribute a fixed proportion of earnings to a superannuation fund on behalf of employees. A majority of these employees can choose an investment strategy for these contributions. We examine how actual investment strategy and asset allocation choices of members change with age in view of the conventional wisdom that individuals allocate less to risky assets as they age and investments theory which provides conflicting advice on the issue.
Capital gains taxation and shareholder wealth in takeovers
Authors: Bugeja Martin , Da Silva Rosa Raymond 
Published: December 2009

AbstractBefore December 1999, the capital gains of shareholders who sold their shares into Australian takeovers have been taxable irrespective of payment method. Subsequently, shareholders can elect to rollover capital gains in equity takeovers. We examine the effect of this change on the association between target shareholder capital gains and bidder and target firm shareholder wealth. The results indicate that prior to the regulatory change, cash consideration results in higher target shareholder returns for non‐taxation reasons. After the introduction of capital gains tax rollover relief, we find that target and acquiring firm shareholders earn lower returns when cash consideration is offered to shareholders with greater capital gains.
SecondSkin: An interactive method for appearance transfer
Authors: Van Den Hengely A. , Sale D. , Dick A. R. 
Published: December 2009

AbstractSecondSkin estimates an appearance model for an object visible in a video sequence, without the need for complex interaction or any calibration apparatus. This model can then be transferred to other objects, allowing a non‐expert user to insert a synthetic object into a real video sequence so that its appearance matches that of an existing object, and changes appropriately throughout the sequence. As the method does not require any prior knowledge about the scene, the lighting conditions, or the camera, it is applicable to video which was not captured with this purpose in mind. However, this lack of prior knowledge precludes the recovery of separate lighting and surface reflectance information. The SecondSkin appearance model therefore combines these factors. The appearance model does require a dominant light‐source direction, which we estimate via a novel process involving a small amount of user interaction. The resulting model estimate provides exactly the information required to transfer the appearance of the original object to new geometry composited into the same video sequence.
Image‐to‐Geometry Registration: a Mutual Information Method exploiting Illumination‐related Geometric Properties
Authors: Corsini Massimiliano , Dellepiane Matteo , Ponchio Federico , Scopigno Roberto 
Published: December 2009

AbstractThis work concerns a novel study in the field of image‐to‐geometry registration. Our approach takes inspiration from medical imaging, in particular from multi‐modal image registration. Most of the algorithms developed in this domain, where the images to register come from different sensors (CT, X‐ray, PET), are based on Mutual Information, a statistical measure of non‐linear correlation between two data sources. The main idea is to use mutual information as a similarity measure between the image to be registered and renderings of the model geometry, in order to drive the registration in an iterative optimization framework. We demonstrate that some illumination‐related geometric properties, such as surface normals, ambient occlusion and reflection directions can be used for this purpose. After a comprehensive analysis of such properties we propose a way to combine these sources of information in order to improve the performance of our automatic registration algorithm. The proposed approach can robustly cover a wide range of real cases and can be easily extended.
Approximate on‐Surface Distance Computation using Quasi‐Developable Charts
Authors: Torchelsen Rafael P. , Pinto Francisco , Bastos Rui , Comba João L. D. 
Published: December 2009

AbstractThere is a vast number of applications that require distance field computation over triangular meshes. State‐of‐the‐art algorithms have quadratic or sub‐quadratic worst‐case complexity, making them impractical for interactive applications. While most of the research on this subject has been focused on reducing the computation complexity of the algorithms, in this work we propose an approximate algorithm that achieves similar results working in lower resolutions of the input meshes. The creation of lower resolution meshes is the essence of our proposal. The idea is to identify regions on the input mesh that can be unfolded into planar regions with minimal area distortion (i.e. quasi‐developable charts). Once charts are computed, their interior is re‐triangulated to reduce the number of triangles, which results in a collection of simplified charts that we call a base mesh. Due to the properties of quasi‐developable regions, we are able to compute distance fields over the base mesh instead of over the input mesh. This reduces the memory footprint and data processed for distance computations, which is the bottleneck of these algorithms. We present results that are one order of magnitude faster than current exact solutions, with low approximation errors.
Simulating Gaseous Fluids with Low and High Speeds
Authors: Gao Yue , Li Chen‐Feng , Hu Shi‐Min , Barsky Brian A. 
Published: December 2009

AbstractGaseous fluids may move slowly, as smoke does, or at high speed, such as occurs with explosions. High‐speed gas flow is always accompanied by low‐speed gas flow, which produces rich visual details in the fluid motion. Realistic visualization involves a complex dynamic flow field with both low and high speed fluid behavior. In computer graphics, algorithms to simulate gaseous fluids address either the low speed case or the high speed case, but no algorithm handles both efficiently. With the aim of providing visually pleasing results, we present a hybrid algorithm that efficiently captures the essential physics of both low‐ and high‐speed gaseous fluids. We model the low speed gaseous fluids by a grid approach and use a particle approach for the high speed gaseous fluids. In addition, we propose a physically sound method to connect the particle model to the grid model. By exploiting complementary strengths and avoiding weaknesses of the grid and particle approaches, we produce some animation examples and analyze their computational performance to demonstrate the effectiveness of the new hybrid method.
A Shape‐Preserving Approach to Image Resizing
Authors: Zhang Guo‐Xin , Cheng Ming‐Ming , Hu Shi‐Min , Martin Ralph R. 
Published: December 2009

AbstractWe present a novel image resizing method which attempts to ensure that important local regions undergo a geometric similarity transformation, and at the same time, to preserve image edge structure. To accomplish this, we define handles to describe both local regions and image edges, and assign a weight for each handle based on an importance map for the source image. Inspired by conformal energy, which is widely used in geometry processing, we construct a novel quadratic distortion energy to measure the shape distortion for each handle. The resizing result is obtained by minimizing the weighted sum of the quadratic distortion energies of all handles. Compared to previous methods, our method allows distortion to be diffused better in all directions, and important image edges are well‐preserved. The method is efficient, and offers a closed form solution.
The Dual‐microfacet Model for Capturing Thin Transparent Slabs
Authors: Dai Qiang , Wang Jiaping , Liu Yiming , Snyder John , Wu Enhua , Guo Baining 
Published: December 2009

AbstractWe present a new model, called the dual‐microfacet, for those materials such as paper and plastic formed by a thin, transparent slab lying between two surfaces of spatially varying roughness. Light transmission through the slab is represented by a microfacet‐based BTDF which tabulates the microfacet's normal distribution (NDF) as a function of surface location. Though the material is bounded by two surfaces of different roughness, we approximate light transmission through it by a virtual slab determined by a single spatially‐varying NDF. This enables efficient capturing of spatially variant transparent slices. We describe a device for measuring this model over a flat sample by shining light from a CRT behind it and capturing a sequence of images from a single view. Our method captures both angular and spatial variation in the BTDF and provides a good match to measured materials.
Fast, Sub‐pixel Antialiased Shadow Maps
Authors: Pan Minghao , Wang Rui , Chen Weifeng , Zhou Kun , Bao Hujun 
Published: December 2009

AbstractSolving aliasing artifacts is an essential problem in shadow mapping approaches. Many works have been proposed, however, most of them focused on removing the texel‐level aliasing that results from the limited resolution of shadow maps. Little work has been done to solve the pixel‐level shadow aliasing that is produced by the rasterization on the screen plane. In this paper, we propose a fast, sub‐pixel antialiased shadowing algorithm to solve the pixel aliasing problem. Our work is based on the alias‐free shadow maps, which is capable of computing accurate per‐pixel shadow, and only incurs little cost to extend to sub‐pixel accuracy. Instead of direct supersampling the screen space, we take facets to approximate pixels in shadow testing. The shadowed area of one facet is rapidly evaluated by projecting blocker geometry onto a supersampled 2D occlusion mask with bitmasks fusion. It provides a sub‐pixel occlusion sampling so as to capture fine shadow details and features. Furthermore, we introduce the silhouette mask map that limits visibility evaluation to pixels only on the silhouette, which greatly reduces the computation cost. Our algorithm runs entirely on the GPU, achieving real‐time performance and is an order of magnitude faster than the brute‐force supersampling method to produce comparable 32× antialiased shadows.
Mesh Segmentation Refinement
Authors: Kaplansky Lotan , Tal Ayellet 
Published: December 2009

AbstractThis paper proposes a method for refining existing mesh segmentations, employing a novel extension of the active contour approach to meshes. Given a segmentation, produced either by an automatic segmentation method or interactively, our algorithm propagates the segment boundaries to more appropriate locations. In addition, unlike most segmentation algorithms, our method allows the boundaries to pass through the mesh faces, resulting in smoother curves, particularly visible on coarse meshes. The method is also capable of changing the number of segments, by enabling splitting and merging of boundary curves during the process. Finally, by changing the propagation rules, it is possible to segment the mesh by a variety of criteria, for instance geometric‐meaningful segmentations, texture‐based segmentations, or constriction‐based segmentations.
Incorporating Sectoral Structure into Shift–Share Analysis
Authors: MÁRQUEZ MIGUEL A. , RAMAJO JULIÁN , HEWINGS GEOFFREY J. D. 
Published: December 2009

ABSTRACTThe objective of this article is to present a new way to incorporate the sectoral dimension within the components of regional growth provided by the traditional shift–share analysis. The new methodology elaborates the way that the dynamics of a specific sector in a region are influenced by the performance of other sectors, the latter decomposed between national, structural, and differential effects. To illustrate this extension of the shift–share method, an application is provided using data for the Spanish region of Extremadura for the period 1990–2004. The results highlight how these new components can shed new insights into the analysis of sectoral and regional economic growth processes.
Urban versus Rural Firms: Does Location Affect Labor Demand?
Authors: HUIBAN JEAN‐PIERRE 
Published: December 2009

ABSTRACTA dynamic labor demand model is developed and estimated on 1,719 French firms in the food industries, observed over the period 1990–1997. Both descriptive statistics and estimation results (including GMM estimations) show that labor demand and its determinants vary according to firm location. Rural areas are characterized by a low adjustment speed and great sensitivity of labor demand to the labor cost. Peri‐urban areas benefit from important economies of scale effects and from technological spillovers. Urban firms are faced with a decline in employment levels, which is mostly due to a faster adjustment of employment to the level of activity. The trade‐off between agglomeration and congestion forces may explain the respective situations of both urban and periurban areas. However, the relative inertia that appears in rural areas may be analyzed in a different way, by considering the smaller number of potential opportunities that exist in these areas.
