Munida miles A. Milne-Edwards 1880
No full textMunida miles A. Milne-Edwards, 1880 Munida miles has been reported from Brazil to the Gulf of Mexico in depths of 68 to 659 m (Milne-Edwards 1880; Henderson 1888; Chace 1942) and has also been reported as Munida decora (see Baba et al. 2008). We used specimens collected in the Gulf of Mexico and Caribbean in depths of 250 to 630 m. Specimens were collected in January, March, May, June, July, November, and December; ovigerous specimens were only collected in May and July (Fig. 9 C). Forty-three males (CW from 4.2 to 16.5 mm), 21 non-ovigerous females (CW from 9.7 to 17.0 mm), and 22 ovigerous were measured (CW from 10.9 to 17.6 mm); males and females were not significantly different in size (t-test, df = 84, t = 0.735, p = 0.464) nor were ovigerous and non-ovigerous females (t-test, df = 41, t = 1.563, p = 0.126). Females carried between 334 and 3224 eggs with an average egg diameter per female range of 0.36 to 0.54 mm. Both, fecundity (R 2 = 0.326, p = 0.005; Fig. 4 E) and the average egg diameter was correlated with CW (R 2 = 0.188, p = 0.044).Published as part of Kilgour, Morgan J. & Shirley, Thomas C., 2014, Reproductive biology of galatheoid and chirostyloid (Crustacea: Decapoda) squat lobsters from the Gulf of Mexico, pp. 381-419 in Zootaxa 3754 (4) on page 397, DOI: 10.11646/zootaxa.3754.4.3, http://zenodo.org/record/22943
Emorroidopessi secondo Longo versus emorroidectomia secondo Milligan-Morgan: analisi prospettica
No full textThe Authors analyzed their experience from January 2001 to February 2005 on 117 patients treated with Longo hemorrhoidopexy (46 cases) and Milligan-Morgan hemorroidectomy (71 cases). All the patients were observed after a week and one month after surgical procedrute; at 6 months the Authors controlled 70 patients treated with Milligan-Morgan and 33 treated with Longo technique. The pain after 24 hours was the same in two groups but after a week a significative difference between two groups (p<0,05) was registered with a better quality of life for hemorrhoidopexy group. At 6 months pain during defectaion was present in two cases of Longo group and in 6 cases of Milligan-Morgan group. In author?s experience the Longo technique is a safe treatment with lower postsurgical pain and lower complication
Persistent hyperammonemia in two related Morgan weanlings
No full textPersistent hyperammonemia was diagnosed in 2 Morgan fillies with clinical signs that developed early in the postweaning period. Diagnostic evaluation, including routine serum chemistries, CBC, liver biopsy, hepatic ultrasonography, liver function test, and necropsy findings did not support a toxic, developmental, or infectious cause. Abnormal serum amino acid and urine orotic acid concentrations suggest that the foals may have had an inherited disorders described in humans as hyperornithinemia, hyperammonemia, and homocitrullinuria (HHH) syndrome. The disorder is thought to be caused by a defective mitochondrial transporter protein, such that ornithine, required for complete urea synthesis, is deficient, thus causing increases in blood ammonia and ornithine concentrations.LR: 20061115; PUBM: Print; JID: 8708660; 0 (Amino Acids); 7006-33-9 (Ornithine); 7664-41-7 (Ammonia); ppublishSource type: Electronic(1
The Performance Advantages for SMEs of Product Innovation and Marketing Resource?Capability Complementarity in Emerging Economies
No full textResearch focusing on SMEs has in many respects been dominated by a developed-economy perspective (Bruton, Ahlstrom, and Obloj 2008). As such, theory and research on SMEs underpinned by a developed economy perspective may not easily translate or apply to SMEs in emerging economies. Grunhagen and Mishra note (2008: 1) “(t)he field of small business and entrepreneurship research is unique in its multidisciplinary approach.” In this sense there is a need to develop a better understanding of entrepreneurship in rapidly emerging economies (Bruton, Ahlstrom, and Obloj 2008). Likewise, while the economic growth of emerging economies is often driven by SMEs, our understanding of how SMEs compete in increasingly competitive emerging economies remains extremely limited (Bruton, Ahlstrom, and Obloj 2008). As such, understanding how SMEs in emerging economies compete is crucial to entrepreneurship scholars, policy makers, and SME owner/managers
A model of process documentation to determine provenance in mash-ups
No full textThrough technologies such as RSS (Really Simple Syndication), Web Services, and AJAX (Asynchronous JavaScript And XML), the Internet has facilitated the emergence of applications that are composed from a variety of services and data sources. Through tools such as Yahoo Pipes, these "mash-ups" can be composed in a dynamic, just-in-time manner from components provided by multiple institutions (i.e. Google, Amazon, your neighbour). However, when using these applications, it is not apparent where data comes from or how it is processed. Thus, to inspire trust and confidence in mash-ups, it is critical to be able to analyse their processes after the fact. These trailing analyses, in particular the determination of the provenance of a result (i.e. the process that led to it), are enabled by process documentation, which is documentation of an application's past process created by the components of that application at execution time. In this paper, we define a generic conceptual data model that supports the autonomous creation of attributable, factual process documentation for dynamic multi-institutional applications. The data model is instantiated using two Internet formats, OWL and XML, and is evaluated with respect to questions about the provenance of results generated by a complex bioinformatics mash-up
An Annotative Approach to Better Hyperauthoring and Associative Linking
No full textEarly hypertext visionaries proposed entire online archives of the world's literature, with everything associatively linked to everything else. Today, the most widespread hypertext system is the World-Wide Web (WWW), a publicly accessible and globally distributed medium. However, the WWW is not living up to the promise of hypertext associativity - the majority of hypertext linking on the WWW is estimated to be intended for navigational purposes only. WWW authors typically have new ideas to contribute, and assert particular relationships between these and existing ideas already published in order to demonstrate both the reliability of the conceptual foundation being built on, and the innovation and significance of the new ideas. However, these associations are rarely rendered as associative links which seamlessly link the new material into the global context. This research investigates the possibility of capturing these implicit inter-document associations through annotation, and then using these annotations to assist the hyperauthoring process. The hypothesis of this work is therefore that by capturing inter-document associations through annotation, a better hyperauthoring process will result, both in terms of the quality and coverage of the new writing, and in terms of the seamless (associative) integration with the global context, helping the WWW evolve to achieve all of its potential hypertextual richness. The Annotation LInking ENvironment (ALIEN) has been implemented to demonstrate techniques for capturing inter-document associations made by an author whilst reading, using free form annotations. Further work proposed includes the re-purposing of these captured associations to assist the authoring and linking processes through dynamic visualisation of the association structures "as-you-type", and automatic associative linking
Essays on Information in Finance
No full textIn the first paper I investigate how firms' disclosure strategies shape the relationship between information disseminated on social media and stock returns. After constructing a novel and comprehensive dataset of over 7 million tweets posted by S&P 1500 firms, I adopt text analysis methods and find that firms with negative earnings surprises have higher announcement returns when they tweet about financial news, despite being ex-ante less likely to tweet about it. Further, I nd that rms which tweet about financial news have less short run autocorrelation in returns and higher demand for information from investors.
The second paper is a joint work with M. J. Arteaga-Garavito, M. M. Croce, and P. Farroni. We quantify the exposure of major financial markets to news shocks about global contagion risk accounting for local epidemic conditions. For a wide cross section of countries, we construct a novel data set comprising (i) announcements related to COVID19, and (ii) high-frequency data on epidemic news diffused through Twitter. Across several classes of financial assets, we provide novel empirical evidence about {financial dynamics (i) around epidemic announcements, (ii) at a daily frequency, and (iii) at an intra-daily frequency.} Formal estimations based on both contagion data and social media activity about COVID19 confirm that the market price of contagion risk is very significant. We conclude that prudential policies aimed at mitigating either global contagion or local diffusion may be extremely valuable.
The third paper is a joint work with Lucia Alessi, Brunella Bruno, Elena Carletti and Katja Neugebauer.
We analyze the determinants of coverage ratios and their components (NPLs and loss loan reserves) in a large sample of European banks. We find that bank-specific factors, and in particular credit risk variables including forward-looking indicators, matter the most. We also uncover that coverage ratios do not adjust sufficiently when asset quality deteriorates but that high-NPL banks tend to be relatively better covered. At the country level, specific macroprudential levers as well as developing NPL secondary markets enhance bank coverage policy. Our findings emphasize the importance of micro prudential oversight and call for more stringent macro policies in high-NPL countries
"Where now the harp?" Listening for the sounds of Old English verse, from Beowulf to the twentieth century
No full textAdditional multimedia to accompany this article is available from http://journal.oraltradition.org/issues/24ii/jonesThis essay examines the representation or staging of oral performance and poetic composition within Beowulf, in order to argue that poem thematizes and mythologizes its own origins, and is as much interested in recovering the sounds of oral performances that pre-date its own manuscript inscription as modern Anglo-Saxon scholarship has been. The second half of the essay considers the recovery and reimagining of an Anglo-Saxon “soundscape” in the work of two twentieth-century poets, W. S. Graham and Edwin Morgan. The invocation of this “Saxonesque” patterning of sound invokes or triggers a historically constituted set of associations with the whole body of Old English poetry; that is, an allusion to a corpus, rather than to a specific text, is made through sound patterning.Peer reviewe

PrIMe: A Methodology for Developing Provenance-Aware Applications
No full textPrIMe is a methodology for adapting applications to make them provenance-aware, that is to enable them to document their execution in order to answer provenance questions. A provenance-aware application can satisfy provenance use cases, where a use case is a description of a scenario in which a user interacts with a system by performing particular functions on that system, and a provenance use case requires documentation of past processes in order to achieve the functions. In this report the PrIMe is described. In order to illustrate the steps necessary to make an application provenance aware, an Organ Transplant Management example application is used
