S. Ashe, K. J. Ahn, R. Leschen, #27, ex. Atta refuse pile (KSEM). Derivation of Name. The specific epithet, refusus, is an adjective identifying the peculiar habitat where the type series was collected. Diagnosis. Along with Tinotus eidmanni, this is the only described species of Tinotus with eyes shorter than the lengths of the temples and each elytron as wide as long. This species differs from T. eidmanni by having completely piceous antennae (the antennae of T. eidmanni have segments 1–4 reddishbrown, segments 5–11 dark brown, and the outer apex of the terminal segments bright brown), a less robust abdomen, the area of greatest width of the abdomen is subequal to the maximum width of the elytra (the area of greatest width of the abdomen of T. eidmanni is greater than the maximum width of the elytra), and the wings not as fully developed, not reaching the apex of the abdomen when extended posteriorly (the wings of T. eidmanni are fully developed). Description. Body length 1.7–2.2 mm. Head piceous to black, pronotum brown to dark brown, elytra and abdomen brown. Body covered throughout with moderately long pile of yellow microsetae; integument reticulate, moderately glossy. Head with eyes small, length about 0.3 times length of temples, pubescence directed anteriorly towards midline. Antennae short, reaching almost basal third of pronotum when extended posteriorly, widest part at segments 6–11 (Fig. 1). Pronotum quadrate to slightly transverse, pubescence evenly distributed, primarly directed towards outer apical angles. Elytra broad, each elytron quadrate, apical margin broadly sinuate, evenly pubescent (Fig. 2), with pubescence directed toward apicolateral angles. Wings small, reaching near middle of abdomen when extended posteriorly. Mesosternum with prominent transverse medial carina (Fig. 3). Male tergum VIII pubescent with numerous heavy spines near outer apical angles (Fig. 4). Aedeagus (Fig. 5), paramere (Fig. 6), spermatheca (Fig. 7) as depicted. Notes. Adults were collected from a large refuse pile of an Atta sp. ant colony. The sampled refuse pile was about a meter tall and contained a wide variety of immature and adult insects (J. S. Ashe, pers. comm.,). It is likely that T. refusus is specific to this habitat since no other specimens were collected in the surrounding area using various hand and trap sampling techniques. In addition, the reduction in size of the eyes, elytra, and wings suggest a lack of mobility, especially through flight. Dispersal of T. refusus may be accomplished by the beetles following the pheromone trails of the host ants as demonstrated by Moser (1964) for the myrmecophilous cockroach Attaphilia fungicola Wheeler, also from Atta colonies.Published as part of Hanley, Rodney S., 2002, A New Species Of Mexican Tinotus From The Refuse Piles Of Atta Ants, Including An Annotated World Catalog Of Tinotus (Coleoptera: Staphylinidae: Aleocharinae: Aleocharini), pp. 453-471 in The Coleopterists Bulletin 56 (4) on page 454, DOI: 10.1649/0010-065X(2002)056[0453:ANSOMT]2.0.CO;2, http://zenodo.org/record/490047
Valuing the attributes of renewable energy investments in Scotland
No full textThis study was funded by a grant from the Scottish Economic Policy Network (SEPN) with funding assistance provided by the University of Glasgow, Department of Economics (Professor Nick Hanley) and the University of Sterling (Robert Wright). The goal of the project was to determine the value of differing types of renewable energy projects by how they would effect environmental and community quality of life factors. The key issues examined include; air quality, landscape, wildlife, and long term local employment. Stated preference methods were employed through the use of a discrete choice experiment survey approach. Willingness-to-pay for different types of renewable energy projects was estimated, i.e., moderate onshore windmill farms, large onshore windmill farms, offshore windmill farms, and biomass fueled power plants. The most significant findings were that rural areas likely to be most highly impacted by the new energy projects were willing to accept low or moderate environmental damage in exchange for commercial development gains. Urban respondents on the other hand were more likely to oppose any disturbance to the landscape or wildlife and had no value placed on the economics development gains for the rural areas; income level of households showed no significant difference in environmental values
Wolcott-Rallison syndrome: pathogenic insights into neonatal diabetes from new mutation and expression studies of EIF2AK3
No full textWolcott-Rallison syndrome (OMIM 226980) is a rare
autosomal recessive disorder characterised by permanent
insulin requiring diabetes developing in the
newborn period or early infancy, an early tendency to skeletal
fractures, and spondyloepiphyseal dysplasia. The syndrome
results from mutations in the gene encoding the eukaryotic
translation initiation factor 2-a kinase 3 (EIF2AK3, also called
PERK or PEK). This enzyme phosphorylates EIF2A at Ser51
to regulate the synthesis of unfolded proteins in the
endoplasmic reticulum. Targeted disruption of the Eif2ak3
gene in mice also causes diabetes because of the accumulation
of unfolded proteins triggering b cell apoptosis.
Although these murine models have provided significant
insight into the pathogenesis of Wolcott-Rallison syndrome,
only three human cases have been characterised genetically.
Here, we report genetic analysis of two further cases,
and demonstrate new features of the expression pattern of
human EIF2AK3 that offer possible explanations for important
clinical features of the syndrome that are not apparent in
the transgenic mouse models
The impacts of elicitation context on stated preferences for agricultural landscapes
No full textFunded by UK Research Council, ESRC, and NERC.Statements of willingness to pay (WTP) have been shown to be dependent upon the framing of the hypothetical market. In this paper we investigate the effects of variations in the timing and location of choice experiment questions concerned with conservation of a UK national park, as research involving measurement of psychological well-being suggests potential differences for the same individual dependent upon when and where preferences are elicited. We apply the choice experiment technique to the valuation of changes in upland agricultural and semi-natural landscapes in the Peak District National Park in the UK, to investigate whether timing and location of elicitation (context) affects the value associated with changes in ecosystem services under different management regimes. Four treatments are employed - using the same sample of individuals answering the same choice scenarios - to measure WTP ex-ante (off site), in situ (on site), and ex-post at two different time intervals (off site). We show that our on-site (in situ) treatment generates very different estimates of preferences than any of the off-site treatments. That stated preferences associated with environmental goods are so context dependent may have implications for the use of stated preferences in policy analysis in terms of identifying how environmental policy is funded and the divergence in value attributed to sampling different populations.Peer reviewe

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
