Open access self-archiving: An Introduction
This, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words, researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate. In a separate exercise we asked the American Physical Society (APS) and the Institute of Physics Publishing Ltd (IOPP) what their experiences have been over the 14 years that arXiv has been in existence. How many subscriptions have been lost as a result of arXiv? Both societies said they could not identify any losses of subscriptions for this reason and that they do not view arXiv as a threat to their business (rather the opposite -- this in fact the APS helped establish an arXiv mirror site at the Brookhaven National Laboratory)
Social Issues of Genome Innovation and Intellectual Property
Dr. Draper\u27s focus is the use of personal information derived from genome research. She identifies several potential problems, including access to and control of genetic information, employment discrimination and social stratification. She also recommends possible solutions
National Traitors In Chicano Culture and Literature: Malinche and Chicano Homosexuals
This article examines the literary representation of a treatment of homosexuality in Mexican/Chicano culture. In this study, Alvarez argues that this cultural treatment is rooted in the gender paradigm central to Mexican/Chicano culture: the narrative of La Malinche
Authors and open access publishing
Surveys were carried out to learn more about authors and open access publishing. Awareness of open access journals among those who had not published in them was quite high; awareness of "self-archiving" wasless. For open access journal authors the most important reason for publishing in that way was the principle of free access; their main concerns were grants and impact. Authors who had not published in an open access journal attributed that to unfamiliarity with such journals. Forty per cent of authors have self-archived their traditional journal articles
and almost twice as many say they would do so if required to

A weighting strategy for Active Shape Models
Active Shape Models (ASM) are an iterative segmentation technique to find a
landmark-based contour of an object. In each iteration, a least-squares fit of
a plausible shape to some detected target landmarks is determined. Finding
these targets is a critical step: some landmarks are more reliably detected
than others, and some landmarks may not be within the field of view of their
detectors. To add robustness while preserving simplicity at the same time, a
generalized least-squares approach can be used, where a weighting matrix
incorporates reliability information about the landmarks. We propose a strategy
to choose this matrix, based on the covariance of empirically determined
residuals of the fit. We perform a further step to determine whether the target
landmarks are within the range of their detectors. We evaluate our strategy on
fluoroscopic X-ray images to segment the femur. We show that our technique
outperforms the standard ASM as well as other more heuristic weighted
least-squares strategies
Open Access and the progress of science
There’s an old joke about asking the way to somewhere and being told it would be best not to start from where you are. It’s a good way to frame some thoughts about whether our present system of scholarly communication aids the progress of science or gets in the way. If we could start now, equipped with the World Wide Web, computers in every laboratory or institution and a global view of the scientific research effort, would we come up with the system for communicating knowledge that we have today? The system we have, which originated as an exchange of letters and lectures among scattered peers, does some things well. But in its current form—a leviathan feeding on an interaction of market forces within and outside science—one can hardly argue that the system satisfies the needs of a modern scientific community. And new developments in the way science is done will make it even less fit for its original purpose in the years ahead. No, we would think of a new way, one that would provide for rapid dissemination of results that any scientist could access, easily and without barriers of cost. We might debate how to implement quality control, how to ensure that originators of ideas or findings are given their proper due, how our new and better system should be In 1996, after more than two decades in medical cell biology research and scholarly publishing, Alma Swan cofounded Key Perspectives Ltd., a consultancy in the area of scholarly communication.
