Virtual Site as an aid to first-year learning

Courses run by the School of the Built Environment have a range of entry requirements that enable diverse students and those with lower academic qualifications to gain entry. This results in a particular challenge for the Documentation & Estimating module, which is a very practical, skillsand competence-based module. It is delivered to large tutorial cohorts of mixed courses, abilities, ages and experience. Many students need one-toone guidance to understand what, practically, they have to do. They are given the theory first in a lecture and then have practical tutorials to carry out assessed exercises with limited tutor contact time. The module includes some basic surveying techniques and a levelling exercise which involves the transfer of a level from an assumed benchmark to establish a temporary benchmark some distance away. Many students have problems with computation of results. In spite of a careful introduction and explanation of the use of the instruments and techniques, many students find it difficult to visualise what is happening

The Empirical Landscape of Trade Policy

This chapter surveys empirically the broad features of trade policy in goods for 31 major economies that collectively represented 83 percent of the world's population and 91 percent of the world's GDP in 2013. We address five questions: Do some countries have more liberal trading regimes than others? Within countries, which industries receive the most import protection? How do trade policies change over time? Do countries discriminate among their trading partners when setting trade policy? Finally, how liberalized is world trade? Our analysis documents the extent of cross-sectional heterogeneity in applied commercial policy across countries, their economic sectors, and their trading partners, over time. We conclude that substantial trade policy barriers remain as an important feature of the world economy.antidumpin

A frotarsius chatrathi, first tarsiiform primate (? Tarsiidae) from Africa

Tarsiiform primates have long been regarded as a Laurasian group, with an extensive fossil record in the Eocene of North America and EuropeI and two important but less well-known records from Asia

Gradual phyletic evolution at the generic level in early Eocene omomyid primates

Analysis of dental morphology in over 600 stratigraphically controlled specimens of tarsier-like primates from early Eocene strata in Bighorn Basin, Wyoming, provides important new data for understanding the tempo and mode of evolution in primates

Patterns of Dental Evolution in Early Eocene Anaptomorphine Primates (Omomyidae) From the Bighorn Basin, Wyoming

ABSTRACT--The subfamily Anaptomorphinae contains the oldest and most generalized members of the tarsier-like primates and is the basal group of the extinct family Omomyidae. The best and most continuous record of anaptomorphine history is from rocks of early Eocene (Wasatchian) age in the Bighorn Basin of northwest Wyoming where eight genera and 14 species are recognized. Three of these species are new (Teilhardina crassidens, Tetonius matthewi, Absarokius metoecus), and four other new species are described from elsewhere (Tetonius mckennai, Absarokius gazini, A. australis, Strigorhysis huerfanensis). Teilhardina tenuicula and Absarokius nocerai are new combined forms. Absarokius noctivagus is considered to be a synonym of A. abbotti, and Mckennamorphus is a synonym of Pseudotetonius

Dentition of the Early Eocene primates Niptomomys and Absarokius

The mandibular dentition of Niptomomys doreenae was previously known only from an edentulous mandible preserving alveolae for all teeth, and jaw fragments preserving P4 and M1-3. A new mandible of Niptomomys is described here which preserves an enlarged, lanceolate lower incisor and a small, blunt, single-rooted P3. The incisor morphology confirms placement of Niptomomys in the Family Microsyopidae. The presence of a single-rooted P3 invalidates the previous interpretation of the lower dental formula. Comparison with the related early primates Navajovius, Palaechthon, Plesiolestes and Uintasorex shows the lower dental formula of Niptomomys to be 1.1.3.3. The total number of teeth in the mandible of Absarokius was previously determined to be eight (except for a single specimen of Absarokius near A. abbotti which Gazin, 1962, suggested might possibly have nine). Two mandibles of A. abbotti described here clearly had nine teeth and a lower 2 dental formula of 2.1.3.3. The upper canine and P2 of this species are also described here for the first time. Comparison of the new specimens of A. abbotti with the later A. noctivagus noceri demonstrates that the tooth previously interpreted in the latter taxon as P2 is in fact the canine, thus the lower dental formula of A.n. noceri is 2.1.2.3, not 1.1.3.3. Absarokius abbotti, with a dental formula of I2?2, C11, P33, M33 seems clearly to be derived from a species of Tetonius

THE ORIGIN OF \u3ci\u3eCHUBUTOLITHES\u3c/i\u3e IHERING, ICHNOFOSSILS FROM THE EOCENE AND OLIGOCENE OF CHUBUT PROVINCE, ARGENTINA

ABSTRACT-The distinctive trace fossil Chubutolithes gaimanensis n. ichnosp. occurs in Casamayoran (early Eocene) and Colhuehaupian (late Oligocene) alluvial rocks of the Sarmiento Formation in eastern Chubut Province, Argentina. Though known for nearly 70 years, its origin has remained obscure. Examination of new specimens and comparisons with modem analogs demonstrate that specimens of Chubutolithes represent the fossil nests of a mud-dauber (Hymenoptera: Sphecidae). Virtually identical nests are constructed today by mud-daubers in areas as disparate as southern Santa Cruz Province, Argentina, and Nebraska, confirming that quite similar trace fossils can be produced by several different taxa in a higher taxonomic clade. No satisfactory ethological term exists for trace fossils that, like Chubutolithes, were constructed by organisms above, rather than within, a substrate or medium. The new term aedificichnia is proposed. Chubutolithes occurs in alluvial paleosols and is associated with a large terrestrial ichnofauna. These trace fossils include the nests of scarab beetles, compound nests of social insects, and burrows of earthworms
