Digital supply chain management in the videogames industry: a systematic literature review
As industries mature, they rely more heavily on supply chain management (SCM) to ensure effective operations leading to greater levels of organisational performance. SCM has been widely covered in many industrial areas and, in line with other burgeoning sectors such as Tourism, an industry focus provides the opportunity to look in-depth at the context-based factors that affect SCM. Developments in digital distribution and rapid technological innovations have resulted in an increased focus on Digital Supply Chains (DSCs), which bring about significant changes to how consumers, customers, suppliers, and manufacturers interact, affecting supply chain design and processes. Through a systematic review of the Videogames Industry Supply Chain Management literature, which serves as a pertinent contextual example of a DSC, we look at how supply chains are affected by structural, market and technological change, such as increased platformisation, disintermediation and the proliferation of digital distribution. We distil these findings into a new research agenda, which identifies themes in line with extant DSC research, provides a series of relevant practice recommendations and identifies opportunities for future research
Wavelength-agnostic WDM-PON system
\u3cp\u3eNext-generation WDM-PON solutions for metro and access systems will take advantage of remotely controlled wavelength-tunable ONUs to keep system costs as low as possible. For such a purpose, each ONU signal can be labeled by a pilot tone modulated onto the optical data stream. We report on the standardization status of this low-cost system in the new ITU-T G.metro draft recommendation, in the context of autonomous tuning. We also discuss some low-effort implementations of the pilot-tone labels and investigate the impact of these labels on the transmission channels.\u3c/p\u3

First results of Herschel-PACS observations of Neptune
We report on the initial analysis of a Herschel/PACS full range spectrum of
Neptune, covering the 51-220 micrometer range with a mean resolving power of ~
3000, and complemented by a dedicated observation of CH4 at 120 micrometers.
Numerous spectral features due to HD (R(0) and R(1)), H2O, CH4, and CO are
present, but so far no new species have been found. Our results indicate that
(i) Neptune's mean thermal profile is warmer by ~ 3 K than inferred from the
Voyager radio-occultation; (ii) the D/H mixing ratio is (4.5+/-1) X 10**-5,
confirming the enrichment of Neptune in deuterium over the protosolar value (~
2.1 X 10**-5); (iii) the CH4 mixing ratio in the mid stratosphere is
(1.5+/-0.2) X 10**-3, and CH4 appears to decrease in the lower stratosphere at
a rate consistent with local saturation, in agreement with the scenario of CH4
stratospheric injection from Neptune's warm south polar region; (iv) the H2O
stratospheric column is (2.1+/-0.5) X 10**14 cm-2 but its vertical distribution
is still to be determined, so the H2O external flux remains uncertain by over
an order of magnitude; and (v) the CO stratospheric abundance is about twice
the tropospheric value, confirming the dual origin of CO suspected from
ground-based millimeter/submillimeter observations.Comment: Accepted for publication in Astronomy & Astrophysics (special issue
