CRIS and Institutional Repositories
Full text linkCRIS (Current Research Information Systems) provide researchers, research managers, innovators, and others with a view over the research activity of a domain. IRs (institutional repositories) provide a mechanism for an organisation to showcase through OA (open access) its intellectual property. Increasingly, organizations are mandating that their employed researchers deposit peer-reviewed published material in the IR. Research funders are increasingly mandating that publications be deposited in an open access repository: some mandate a central (or subject-based) repository, some an IR. In parallel, publishers are offering OA but replacing subscription-based access with author (or author institution) payment for publishing. However, many OA repositories have metadata based on DC (Dublin Core) which is inadequate; a CERIF (Common-European Research Information Format) CRIS provides metadata describing publications with formal syntax and declared semantics thus facilitating interoperation or homogeneous access over heterogeneous sources. The formality is essential for research output metrics, which are increasingly being used to determine future funding for research organizations
Latin American Theories of Development and Underdevelopment
No full textUpon its publication in 1989, this was the first systematic and comprehensive analysis of the Latin American School of Development and an invaluable guide to the major Third World contribution to development theory. The four major strands in the work of Latin American Theorists are: structuralism, internal colonialism, marginality and dependency. Exploring all four in detail, and the interconnections between them, Cristobal Kay highlights the developed world’s over-reliance on, and partial knowledge of, dependency theory in its approach to development issues, and analyses the first major challenges to neo-classical and modernisation theories from the Third World

Full text linkHigh-resolution tropospheric carbon monoxide profiles retrieved from CrIS and TROPOMI
Full text linkThe Measurements of Pollution in the Troposphere (MOPITT) instrument is the
only satellite-borne sensor in operation that uses both thermal (TIR) and
near-infrared (NIR) channels to estimate CO profiles. With more than 15
years (2000 to present) of validated multispectral observations, MOPITT
provides the unique capability to separate CO in the lowermost troposphere (LMT, surface to 3 km (∼ 700 hPa)) from the free-tropospheric
abundance. To extend this record, a new, hyper-spectral approach is
presented here that will provide CO data products exceeding the capabilities
of MOPITT by combining the short-wavelength infrared (SWIR, equivalent to
the MOPITT NIR) channels from the TROPOspheric Monitoring Instrument
(TROPOMI) to be launched aboard the European Sentinel 5 Precursor (S5p)
satellite in 2016 and the TIR channels from the Cross-track Infrared
Sounder (CrIS) aboard the Suomi National Polar-orbiting Partnership (Suomi NPP)
satellite. We apply the MUlti-SpEctra, MUlti-SpEcies, Multi-SEnsors (MUSES)
retrieval algorithm to quantify the potential of this joint CO product. CO
profiles are retrieved from a single-footprint, full-spectral-resolution
CrIS transect over Africa on 27–28 August 2013 coincident with significant
biomass burning. Comparisons of collocated CrIS and MOPITT CO observations
for the LMT show a mean difference of 2.8 ± 24.9 ppb, which is well
within the estimated measurement uncertainty of both sensors. The estimated
degrees of freedom (DOF) for CO signals from synergistic CrIS–TROPOMI
retrievals are approximately 0.9 in the LMT and 1.3 above the LMT, which
indicates that the LMT CO can be distinguished from the free troposphere,
similar to MOPITT multispectral observations (0.8 in the LMT, and 1.1
above the LMT). In addition to increased sensitivity, the combined retrievals reduce measurement uncertainty, with ∼ 15 % error reduction
in the LMT. With a daily global coverage and a combined spatial footprint of 14 km, the joint CrIS–TROPOMI measurements have the potential to extend and
improve upon the MOPITT multispectral CO data records for the coming
decade
