No full textNeogergithoides Sun, Meng & Wang, gen. nov. Type species: Neogergithoides tubercularis sp . nov. by monotypy Description. Body hemispherical. Head with eyes distinctly narrower than pronotum. Vertex more or less hexagonal, tricarinate, 1.7 times longer than broad, anterior margin weakly convex at middle, posterior margin shallowly emarginate, disc depressed. Frons smooth, 1.8 times longer than broad, anteriorly truncate and moderately produced above eyes, slightly convex and narrowed towards clypeus, disk elevated with median carina; lateral margin clearly carinated. Clypeus elongate and triangulate, strongly elevated at disc, median carina present. Rostrum long, reaching post-trochanters. Eyes oval, ocelli present. Pronotum short, about half of vertex in mid-line, anterior margin convex onwards between eyes, with two central pits at disc, median carina present or obsolete, posterior margin elevated. Mesonotum more or less triangular with median and lateral carinae, with two pits along each lateral margin. Tegula small. Tegmen longer than broad, semicoriaceous and without claval suture, approximately 2.0 times longer in midline than wide at widest part, veins distinct and reticulate. Wing translucent, veins distinct and netlike, longer than half length of tegmen. Legs moderately long, not dilated; lateral margin of hind tibia with two teeth. Spinal formula of hind leg 6–9 – 2. Male genitalia. Anal segment in dorsal view mushroom-shaped. Pygofer in profile with dorsolateral angles strongly produced. Aedeagus slightly curved downward medially, with dorsal, lateral and ventral lobes, two short sword-like processes near middle. Genital styles in lateral view subtriangular, caudo-ventral angle rounded. Capitulum of style, in dorsal view, with two obtuse apical processes, and large lateral tooth. Female genitalia. Sternite VII with apical margin distinctly convex at middle. Anal segment in dorsal view oval-like. Anterior connective laminae of gonapophysis VIII nearly quadrilateral, with three nearly parallel teeth at apical margin; lateral margin with three small teeth with carinae at apex. Posterior connective laminae of gonapophyses IX nearly square in lateral view, lateral fields flat, median field wide and single. Gonoplac nearly quadrilateral, in dorsal view, fused at base and forked at apical half along dorsal margin. Remarks. The new genus is placed into the tribe Hemisphaeriini by the following combination of characteristics: body hemispherical; head with eyes narrower than pronotum; tegmen coriaceous and relatively thick, without claval suture; wing developed, and shorter than tegmen; lateral margin of hind tibia with two teeth. This new genus resembles Gergithoides Schumacher but differs from the latter by the following characters: 1) ocelli present, absent in Gergithoides; 2) vertex with tricarinate, about 1.7 times longer than wide, in Gergithoides, vertex with median carina or not, almost as long at base as wide in middle line; 3) frons without any tubercule and elevated at disc, posterior margin of pronotum with indistinct tubercules, in Gergithoides, frons with numerous tubercules along lateral margin and flat at disc, anterior and posterior margin of pronotum with distinct tubercules; 4) tegmen with a brown stripe along black anterior and apical margins, and anterior margin moderately convex at one third of base, Gergithoides without such stripe and anterior margin arc; 5) aedeagus with two short sword-like processes in basal half, Gergithoides with two processes at apical half. This new genus is also similar to Macrodaruma Fennah, but can be separated from the latter by the following characters: 1) vertex more or less hexagonal, slightly produced, in Macrodaruma, vertex almost trapezoidal and strongly produced, tapering; 2) pronotum with indistinct median carina, absent in Macrodaruma; 3) frons with lateral margin elevated, in Macrodaruma, lateral margin flat; 4) aedeagus with two short sword-like processes apex directed dorsally near middle, the Macrodaruma with two short processes apex directed basally at base. The similarity of some characters of the new genus, particularly the presence of the median carina on the frons, indicates that it is probably closer to Gergithoides, Macrodaruma, Mongoliana and Choutagus than other genera in the subfamily Hemisphariini, but it needs to be verified based on further phylogenetic research by using molecular and morphologic data as well. Etymology. The generic name “ Neogergithoides ” refers to the strong resemblance to Gergithoides. The genus is feminine in gender.Published as part of Sun, Yanchun, Meng, Rui & Wang, Yinglun, 2012, Neogergithoides, a new genus with a new species from China (Hemiptera: Issidae), pp. 42-53 in Zootaxa 3186 on pages 43-44, DOI: 10.5281/zenodo.28000
Wang Meng and contemporary Chinese literature: the vicissitudes of a committed writer
No full textThis thesis examines the way Wang Meng has developed as a writer from the 1950s to the 1990s in the context of New China's political and literary background. It looks at the compromises he was forced to make between his political beliefs in the Communist Party and his chosen role as a professional writer. After his disastrous early foray into what was deemed to be unacceptable political criticism with The Young Newcomer in the Organisation Department in the 1950s, when the opportunity came to start publishing again in the late 1970s he was boldly innovative in style, helping to transform New Period literature, but conservative in content, sticking to politically acceptable topics. It was only with Hard Porridge in 1989 that he ventured again, and very successfully, into political comment. There is no outstanding leading writer in contemporary China, but Wang Meng is a leading contender for the title

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

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
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

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
