Does information help recovering structural shocks from past observations?

This paper asks two questions. First, can we detect empirically whether the shocks recovered from the estimates of a structural VAR are truly structural Second, can the problem of nonfundamentalness be solved by considering additional information? The answer to the first question is “yes” and that to the second is “under some conditions”. JEL Classification: C32, C33, E00, E32, O3C33, E00, E32, JEL Classification: C32, O3

[μ-3,3′-Bis(tri­hydro­bor­yl)[3]ferroceno­phane]bis­(chlorido­zirconocene)

The title compound, [FeZr2(C5H5)4Cl2(C13H18B2)], is a heteronuclear complex that consists of a [3]ferrocenophane moiety substituted at each cyclo­penta­dienyl (Cp) ring by a BH3 group; the BH3 group is bonded via two H atoms to the Zr atom of the zirconocene chloride moiety in a bidentate fashion. The two Cp rings of the [3]ferrocenophane moiety are aligned at a dihedral angle of 8.9 (4)° arising from the strain of the propane-1,3-diyl bridge linking the two Cp rings. [One methyl­ene group is disordered over two positions with a site-occupation factor of 0.552 (18) for the major occupied site.] The dihedral angles between the Cp rings at the two Zr atoms are 50.0 (3) and 51.7 (3)°. The bonding Zr(...)H distances are in the range 1.89 (7)–2.14 (7) Å. As the two Cp rings of the ferrocene unit are connected by an ansa bridge, the two Zr atoms approach each other at 6.485 (1) Å.

Management objectives of some revegetation plantings encourage the use of native species. Where reinstatement of a native flora is desired, the inclusion of suitable native materials can hasten the process. Further, properly adapted native plants may provide a persistent, winterhardy cover requiring little management. The use of poorly adapted introduced grasses can result in stand decimation, such as that experienced along southcentral Alaska’s roadsides after the severe winter of 1975-1976 (Klebesadel, 1977). Tests have revealed, however, that not all indigenous materials are suitable for revegetation purposes. Some have been insufficiently winterhardy for general use, as apparently their ability to persist in their native habitat is related to the particular set of conditions in which they occur. Susceptibility to diseases or failure to persist well in a dense stand militates against the use of certain native types. Growth form also must be considered. If the objective of a planting is to maintain a fairly uniform , turf-like growth, then tall, coarse-growing plants should be avoided. Patience is required in the use of native plants in that their seedling vigor is often low compared to that of m any commercially available cultivars, and the natives may be suppressed when seeded along with more vigorous cultivars. The investigations on revegetation in conjunction with the Prudhoe Bay oil field and trans- Alaska pipeline activities have resulted in the release o f three cultivars derived from indigenous Alaskan materials. Many o f the collections for these cultivars were made prior to 1969 and some date back to 1966. The establishment of this material in small nurseries at the Palmer Experiment Station prior to the oil field activity enabled seed to be obtained for the early testing programs. The three cultivars were developed primarily for revegetation purposes and are particularly important to arctic rehabilitation efforts (Mitchell, 1978) where the need for additional material is most pressing. One cultivar, Tundra, is recommended strictly for arctic use. The other two, Alyeska and Sourdough, can be applied throughout mainland Alaska in appropriate situations. The latter two may also have application as forage grasses in areas where other available materials may be poorly adapted.Preface -- Introduction -- Varieties: Tundra Glaucous Bluegrass, Alaska Polargrass, Sourdough Bluejoint Reedgrass -- Summary -- Acknowledgements -- Reference

[my]-Hydroxido-bis[(2,20-bipyridine)-tricarbonylrhenium(I)] perrhenate

The title compound, [Re2(OH)(C10H8N2)2(CO)6][ReO4], is a mixed-valence rhenium compound containing discrete anions and cations. The ReI atoms are in a slightly distorted octahedral environment, whereas the ReVII atoms show the typical tetrahedral coordination mode. The dihedral angle between the two bipyridine groups is 34.3 (7)°.
