A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
RoMEO Studies 6: Rights metadata for open-archiving
No full textThis is the final study in a series of six emanating from the UK JISC-funded RoMEO Project (Rights Metadata for Open-archiving) which investigated the Intellectual Property Rights (IPR) issues relating to academic author self-archiving of research papers. It reports the results of a survey of 542 academic authors showing the level of protection required for their open-access research papers. It then describes the selection of an appropriate means of expressing those rights through metadata and the resulting choice of Creative Commons licences. Finally it outlines proposals for communicating rights metadata via the Open Archives Initiative’s Protocol for Metadata Harvesting (OAI-PMH)

Developing a model for e-prints and open access journal content in UK further and higher education
No full textA study carried out for the UK Joint
Information Systems Committee examined models for the
provision of access to material in institutional and
subject-based archives and in open access journals. Their
relative merits were considered, addressing not only
technical concerns but also how e-print provision (by
authors) can be achieved – an essential factor for an
effective e-print delivery service (for users). A "harvesting" model is recommended, where the metadata of articles deposited in distributed archives are harvested, stored and enhanced by a national service. This model has major advantages over the alternatives of a national centralized service or a completely decentralized one. Options for the implementation of a service based on the harvesting model are presented
R U Up for the Challenge? A Partnership to Measure Library Impact on Student Learning: Rutgers University Libraries & Ronald E. McNair Post Baccalaureate Degree Achievement Program
No full textRutgers University Libraries seek to support the goal of the Rutgers University Mission Assessment and Alignment Planning system (MAAP) which is "to clarify the contributions of various programs and units to the fulfillment of the Rutgers-New Brunswick undergraduate educational experience mission/goals, and to facilitate and encourage assessment and alignment of outcomes and progress toward those goals." Toward this end, the Libraries have focused on measuring the impact of its instruction program via the McNair Post Baccalaureate Achievement Program (MPBAP). This prestigious program provides a unique opportunity to track cohorts of students over 10 years. The goal is to have these students enroll in doctoral programs. We are seeking to find out: Do students in the Bibliography & Research Techniques library class in the Summer Research Institute of the MPBAP retain and transfer information literacy skills to other courses and academic research as they persist in the MPBAP program? In addition to the assessment instruments already in use by the McNair department, (Graduate Student Profile Progress Report) for long term impact, other instruments are being used by the Libraries: pre-post tests and surveys. This poster will present the assessment methods in place as we begin to track our first cohort (Summer 2015).This project is part of the program “Assessment in Action: Academic Libraries and Student Success” which is undertaken by the Association of College and Research Libraries (ACRL) in partnership with the Association for Institutional Research and the Association of Public and Land-grant Universities. The program, a cornerstone of ACRL's Value of Academic Libraries initiative, is made possible by the Institute of Museum and Library Services
On quadratic Waring’s problem in totally real number fields

Publisher Copyright: © 2023 American Mathematical Society.We improve the bound of the g-invariant of the ring of integers of a totally real number field, where the g-invariant g(r) is the smallest number of squares of linear forms in r variables that is required to represent all the quadratic forms of rank r that are representable by the sum of squares. Specifically, we prove that the gOK(r) of the ring of integers OK of a totally real number field K is at most gZ([K : Q]r). Moreover, it can also be bounded by gOF ([K : F]r + 1) for any subfield F of K. This yields a subexponential upper bound for g(r) of each ring of integers (even if the class number is not 1). Further, we obtain a more general inequality for the lattice version G(r) of the invariant and apply it to determine the value of G(2) for all but one real quadratic field.Peer reviewe
Open access self-archiving: An author study
No full textThis, 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

RoMEO Studies 4: An analysis of Journal publishers' Copyright Agreements
No full textThis article is the fourth in a series of six emanating from the UK JISC-funded RoMEO Project (Rights Metadata for Open archiving). It describes an analysis of 80 scholarly journal publishers’ copyright agreements with a particular view to their effect on author self-archiving. 90% of agreements asked for copyright transfer and 69% asked for it prior to refereeing the paper. 75% asked authors to warrant that their work had not been previously published although only two explicitly stated that they viewed self-archiving as prior publication. 28.5% of agreements provided authors with no usage rights over their own paper. Although 42.5% allowed self-archiving in some format, there was no consensus on the conditions under which self-archiving could take place. The article concludes that author-publisher copyright agreements should be reconsidered by a working party representing the needs of both partie
