Assessment of Self-Archiving in Institutional Repositories: Depositorship and Full-Text Availability
No full textThis research evaluates the success of open access self-archiving in several well-known institutional repositories. Two assessment factors have been applied to examine the current practice of self-archiving: depositorship and the availability of full text. This research discovers that the rate of author self-archiving is low and that the majority of documents have been deposited by a librarian or administrative staff. Similarly, the rate of full-text availability is relatively low, except for Australian repositories. By identifying different practices of self-archiving, repository managers can create new strategies for the operation of their repositories and the development of archiving policies

Association between early career nurses’ social jetlag, affect, depression, and quality of life
No full textBackground: Social jetlag in nurses is a long-standing challenge for nursing management. It has been attributed to the effects of shift work that disrupts nurses circadian rhythms, may be detrimental to their health, and can lead to rapid turnover. Aim: We aimed to identify the association between social jetlag, affect, depression, and quality of life of early career nurses. Methods: In this cross-sectional study, 201 early career nurses at three tertiary hospitals in South Korea were included. Data were collected from May to July 2018. Social jetlag, affect, depression, and quality of life were measured using the Munich Chronotype Questionnaire (shift version), the Positive and Negative Affect Scale, the Centre for Epidemiological Studies Depression Scale (Korean version), and the Korean World Health Organization Quality of Life Scale (abbreviated version), respectively. Findings: Participants mean overall social jetlag and quality of life scores were 4 hours 28 minutes and 80.21, respectively. Multiple regression analyses identified overall social jetlag, positive and negative affect, and depression as factors influencing the nurses quality of life. Discussion: Understanding the implications of factors affecting early career nurses quality of life, including social jetlag, is vital to ensure staff retention. Nursing management should consider the individual social jetlag of nurses when scheduling shifts and accordingly create institutional human resources management strategies to reduce negative affect and depression while promoting positive affect in early career nurses. Conclusion: Social jetlag, negative affect, and depression negatively impact early career nurses quality of life, whereas positive affect positively impacts their quality of life.Y
Applying the NISO Metasearch Initiative Scheme to Enhance E-Resources Management at Rutgers University Library
No full textThis paper discusses problems in the management of library e-resources and attempts to identify potential solutions to the problems. By describing an e-resources enhancement project taken by Rutgers University Libraries, this paper points to the importance of providing contextually-rich metadata and reorganizing the accessibility of e-resources on a library’s website. It introduces how this Rutgers project adopted the National Information Standards Organization Metasearch Initiative to support the identification of appropriate e-collections for metaseaching. The outcomes of the project have facilitated a dynamic display of relevant e-resources to library users as an effective way of automatic access to library e-collections.Peer reviewe
Social jetlag and quality of life among nursing students: A cross‐sectional study
No full textAims To investigate chronotype categories and social jetlag among nursing students and to identify associations between rhythm asynchrony and participants' physical and psychological health, academic performance and quality of life. Background Social jetlag refers to the asynchrony between chronotypes and social working hours, resulting in a misalignment of biological and social time. Recent studies have reported possible changes in psychosocial functioning owing to social jetlag. Therefore, the present study investigated chronotypes and the extent of social jetlag among nursing students. Design A cross-sectional study was conducted in 2015 with a sample of 346 nursing students in two universities in Korea. Methods Social jetlag and quality of life were measured with the Munich Chronotype Questionnaire and the abbreviated version of the World Health Organization Quality of Life Scale, respectively, in the year 2015. Data analysis was mainly based on a multiple regression to identify social jetlag's influence on students' quality of life. Results Average social jetlag was 1 hr - 36 min. Social jetlag was negatively correlated with chronotype, academic performance and quality of life. A multiple regression analysis revealed that social jetlag, a positive emotional state, recovery resilience and depressive symptoms affected students' quality of life. These variables accounted for 41.7% of the variance in quality of life. Conclusions Results suggest that decreases in social jetlag and depressive symptoms, as well as increases in the positive emotional state and recovery resilience, enhance students' quality of life.N
A Metadata Manager's Role in Collaborative Projects: The Rutgers University Libraries Experience
No full textPurpose – This article discusses the roles and responsibilities of a metadata manager in collaborative digital projects.
Methodology – It describes the general requirements for metadata management, and introduces some scenarios in the practices of digital projects by the Rutgers University Libraries to support the generalized definition. A workflow of metadata management is illustrated.
Practical implications – With an explicit definition of the roles and responsibilities of the metadata manager, many other digital libraries that need to develop a new or optimize the existing workflow may find the Rutgers experience useful as reference.
Originality – Very few articles have explored this topic although the functions of metadata in the development of digital projects have been talked extensively.Peer reviewe
Factors to Assess Self-Archiving in Institutional Repositories

Extension of the sun-synchronous Orbit
No full textThrough careful consideration of the orbit perturbation force due to the oblate nature of the primary body a secular variation of the ascending node angle of a near-polar orbit can be induced without expulsion of propellant. Resultantly, the orbit perturbations can be used to maintain the orbit plane in, for example, a near-perpendicular (or at any other angle) alignment to the Sun-line throughout the full year of the primary body; such orbits are normally termed Sun-synchronous orbits [1, 2]. Sun-synchronous orbits about the Earth are typically near-circular Low-Earth Orbits (LEOs), with an altitude of less than 1500 km. It is normal to design a LEO such that the orbit period is synchronised with the rotation of the Earth‟s surface over a given period, such that a repeating ground-track is established. A repeating ground-track, together with the near-constant illumination conditions of the ground-track when observed from a Sun-synchronous orbit, enables repeat observations of a target over an extended period under similar illumination conditions [1, 2]. For this reason, Sun-synchronous orbits are extensively used by Earth Observation (EO) platforms, including currently the Environmental Satellite (ENVISAT), the second European Remote Sensing satellite (ERS-2) and many more. By definition, a given Sun-synchronous orbit is a finite resource similar to a geostationary orbit. A typical characterising parameter of a Sun-synchronous orbit is the Mean Local Solar Time (MLST) at descending node, with a value of 1030 hours typical. Note that ERS-1 and ERS-2 used a MLST at descending node of 1030 hours ± 5 minutes, while ENVISAT uses a 1000 hours ± 5 minutes MLST at descending node [3]. Following selection of the MLST at descending node and for a given desired repeat ground-track, the orbit period and hence the semi-major axis are fixed, thereafter assuming a circular orbit is desired it is found that only a single orbit inclination will enable a Sun-synchronous orbit [2]. As such, only a few spacecraft can populate a given repeat ground-track Sun-synchronous orbit without compromise, for example on the MLST at descending node. Indeed a notable feature of on-going studies by the ENVISAT Post launch Support Office is the desire to ensure sufficient propellant remains at end-of-mission for re-orbiting to a graveyard orbit to ensure the orbital slot is available for future missions [4]. An extension to the Sun-synchronous orbit is considered using an undefined, non-orientation constrained, low-thrust propulsion system. Initially the low-thrust propulsion system will be considered for the free selection of orbit inclination and altitude while maintaining the Sun-synchronous condition. Subsequently the maintenance of a given Sun-synchronous repeat-ground track will be considered, using the low-thrust propulsion system to enable the free selection of orbit altitude. An analytical expression will be developed to describe these extensions prior to then validating the analytical expressions within a numerical simulation of a spacecraft orbit. Finally, an analysis will be presented on transfer and injection trajectories to these orbits
