"Back to basics" : a cognitive analysis of conversion de-adjectival nominalisation in English
(2003)
The experience in the period during and after the Asian crisis of 1997-98 has provoked an extensive debate about the credit rating agencies' evaluation of sovereign risk in emerging markets lending. This study analyzes the role of credit rating agencies in international finan-cial markets, particularly whether sovereign credit ratings have an impact on the financial stability in emerging market economies. The event study and panel regression results indicate that credit rating agencies have substantial influence on the size and volatility of emerging markets lending. The empirical results are significantly stronger in the case of government's downgrades and negative imminent sovereign credit rating actions such as credit watches and rating outlooks than positive adjustments by the credit rating agencies while by the market participants' anticipated sovereign credit rating changes have a smaller impact on financial markets in emerging economies.
Proceeding chronologically in terms of the events covered, Raimund Schieß in his paper „Too close to call: CNN’s politics of captions in the coverage of the Florida Recount“ focusses on Nov. 11, 2000, when the Bush campaign applied to Miami Federal Court to stop the manual recount of ballots which had been started in some counties. The paper studies the discursive practices employed by the CNN journalists to construct a particular version of the events, focussing on captions, i.e. the lines of text inserted at the bottom of the tv screen, and on the way in which they interact with the other verbal and visual components of the television text. Raimund Schieß concludes that captions, far beyond providing mere details of a speech event (who is talking to whom about what, where and when), are used to select, to highlight and hide, and thus to invite a preferred interpretation of the event. He is also able to show that captions are often employed to exploit a story’s potential for drama and sensation. His detailed micro-analysis of the verbal and visual dimensions of the television text is supported by careful documentation of the data, either through screen shots or via transcriptions of the stretches of broadcast discussed.
Cytochrome P450-derived epoxyeicosatrienoic acids (EETs) stimulate endothelial cell proliferation and angiogenesis. In this study, we investigated the involvement of the forkhead box, class O (FOXO) family of transcription factors and their downstream target p27Kip1 in EET-induced endothelial cell proliferation. Incubation of human umbilical vein endothelial cells with 11,12-EET induced a time- and dose-dependent decrease in p27Kip1 protein expression, whereas p21Cip1 was not significantly affected. This effect on p27Kip1 protein was associated with decreased mRNA levels as well as p27Kip1 promoter activity. 11,12-EET also stimulated the time-dependent phosphorylation of Akt and of the forkhead factors FOXO1 and FOXO3a, effects prevented by the phosphatidylinositol 3-kinase inhibitor LY 294002. Transfection of endothelial cells with either a dominant-negative or an “Akt-resistant”/constitutively active FOXO3a mutant reversed the 11,12-EET-induced down-regulation of p27Kip1, whereas transfection of a constitutive active Akt decreased p27Kip1 expression independently of the presence or absence of 11,12-EET. To determine whether these effects are involved in EET-induced proliferation, endothelial cells were transfected with the 11,12-EET-generating epoxygenase CYP2C9. Transfection of CYP2C9 elicited endothelial cell proliferation and this effect was inhibited in cells co-transfected with CYP2C9 and either a dominant-negative Akt or constitutively active FOXO3a. Reducing FOXO expression using RNA interference, on the other hand, attenuated p27Kip1 expression and stimulated endothelial cell proliferation. These results indicate that EET-induced endothelial cell proliferation is associated with the phosphatidylinositol 3-kinase/Akt-dependent phosphorylation and inactivation of FOXO factors and the subsequent decrease in expression of the cyclin-dependent kinase inhibitor p27Kip1.
This is a catalogue of 23 described and 6 undescribed genera, and 48 described and 157 undescribed species of West Indian Anthribidae distributed from the Bahamas to Grenada. Each described genus has author, date, page, type species and how designated, World distribution, number of World species, and synonyms. Each described species has author, date, page, original generic name if a transfer has occurred, type locality, sex and location of type(s) if known, synonyms, and island-by-island distribution. New taxa are numbered, with data on museum location and island distribution. There are brief comments on New World distributions as they relate to the Antilles, and on missing Suffrian and Wolfrum types.
We present an approach to the interpretation of non-sentential utterances like B's utterance in the following mini-dialogue:
A: "Who came to the party?"
B: "Peter."
Such utterances pose several puzzles: they convey 'sentence-type' messages (propositions, questions or request) while being of non-sentential form; and they are constrained both semantically and syntactically by the context. We address these puzzles in our approach which is compositional, since we provide a formal semantics for such fragments independent of their context, and constraint-based because resolution is based on collecting contextual constraints.
This paper provides a constraint-based account of information-prosody correspondence within the HPSG framework. The starting point of the paper is Klein's (2000) account of prosodic constituency in HPSG. However, it departs from the standard syntactocentric architecture of grammar, and adopts a grammar design in which syntax, phonology, and information structure are generated in parallel, with all three applying to a common list of domain objects. It is shown that this theoretical architecture elegantly captures many of the various constraints that have been shown to hold in classical views of grammar.
This paper deals with the proposed use of sovereign credit ratings in the "Basel Accord on Capital Adequacy" (Basel II) and considers its potential effect on emerging markets financing. It investigates in a first attempt the consequences of the planned revisions on the two central aspects of international bank credit flows: the impact on capital costs and the volatility of credit supply across the risk spectrum of borrowers. The empirical findings cast doubt on the usefulness of credit ratings in determining commercial banks' capital adequacy ratios since the standardized approach to credit risk would lead to more divergence rather than convergence between investment-grade and speculative-grade borrowers. This conclusion is based on the lateness and cyclical determination of credit rating agencies' sovereign risk assessments and the continuing incentives for short-term rather than long-term interbank lending ingrained in the proposed Basel II framework.
The SENECA model, a new hybrid approach to air shower simulations, is presented. It combines the use of efficient cascade equations in the energy range where a shower can be treated as one-dimensional, with a traditional Monte Carlo method which traces individual particles. This allows one to reproduce natural fluctuations of individual showers as well as the lateral spread of low energy particles. The model is quite efficient in computation time. As an application of the new approach, the influence of the low energy hadronic models on shower properties for AUGER energies is studied. We conclude that these models have a significant impact on the tails of lateral distribution functions, and deserve therefore more attention.
