Moreover, studies looking systematically at family involvement and possible variations within the same origin group across several European countries are scarce (for exceptions, however, see Crul, 2013; Schnell, 2014; Schnell & Crul, 2014).
Whereas many recent papers on specific aspects of Germany's transport policy exist, papers with a broader focus on Germany's transport policy for the period after reunification are scarce (one exception is [40], for an earlier comprehensive assessment see [5]) and some of them were only published in German language.
National retailers, on the other hand, have been scarce, with the exception of recent entrants like a Washington Mutual bank and an American Apparel store.
Sculpture and installation are also scarce, with the exception of the Puerto Rican Pepón Osorio's "Bed" (1987), a marvel of opulent, decorative excess.
The evidence for this is scarce: with the exception of Denmark, centre-left parties are struggling across the democratic world, as voters grudgingly accept that the years of big spending are over.

Forward and backward linkages between SMEs and LSEs, in which the former are involved in the co-production and postproduction of goods manufactured by the latter is scarce, with the exception of the automobile sector where there is nevertheless still ample scope for a further increase of backward linkages.
The complete generation equivalent has also been greatly variable, although in general scarce, with the exception of the Pirenaica breed, with a mean of 3.8.
Overall, if we except species with a clear dispersal-dedicated apparatus [ 24, 45, 47, 58], evidence for genetic variation in dispersal syndromes and close dissections of trait associations are scarce (for a few exceptions [ 39, 41, 44], see also [ 38]).
Independent evaluations are scarce with the notable exception of the work by the Video Quality Experts Group VQEGG) [14].
