Have patients with esophagitis got an increased risk of adenocarcinoma?:Results from a population-based study

To examine an increased risk of esophageal adenocarcinoma is restricted to patients who develop Barrett's esophagus or whether esophagitis per se is a risk factor for adenocarcinoma.

Italy's got talent. How Italian leading companies in confectionery industry overcame the crisis

The crisis that spread worldwide since 2007 started from the financial sector and ended to affect also real economy. This process has attracted the attention of many scholars seeking to study its causes and impacts. Notwithstanding many works on this topic, the impact of the crisis on specific industries is still rather unexplored. The present work seeks to address this issue by analyzing the confectionery industry, with particular emphasis for Italian market leaders, Ferrero S.p.A. and Perfetti Van Melle S.r.l.. The aim of the study is to assess if they have been successful in tackling the crisis, keeping a satisfactory level of profitability associated to a good financial health notwithstanding ongoing difficulties. Moreover, we seek to analyze the strategies the companies employed to survive the crisis. The concern of the paper is both quantitative and qualitative. Thus, we calculated a complete set of indicators using a specific methodology for financial statement analysis which has been conceived especially for studying Italian firms; these data have been integrated with other information retrieved from the annual reports of the companies (especially the notes to the accounts and the directors’ report). The analysis highlights that both the firms benefit from a good financial health, with Perfetti Van Melle presenting a large amount of liquidity. On the contrary, liquidity should be the main concern of Ferrero because of an excessive reliance on current liabilities. Both the firms have a good level of profitability, even if Perfetti Van Melle’s one is decreasing. The key-strategies for the success of these firms are ongoing investments in state-of-the-art plant and machinery, an increasing use of equity as the main source of funding, along with huge investments in research and advertising.

What’s information got to do with it? Third-party voting in plurality systems

Although strategic voting theory predicts that the number of parties will not exceed two in single-member district plurality systems, the observed number of parties often does. Previous research suggests that the reason why people vote for third parties is that they possess inaccurate information about the parties’ relative chances of winning. However, research has yet to determine whether third-party voting persists under conditions of accurate information. In this article, we examine whether possessing accurate information prevents individuals from voting for third-placed parties in the 2005 and 2010 British elections. We find that possessing accurate information does not prevent most individuals from voting for third-placed parties and that many voters possess reasonably accurate information regarding the viability of the parties in their constituencies. These findings suggest that arguments emphasizing levels of voter information as a major explanation for why multiparty systems often emerge in plurality systems are exaggerated.

How the mollusc got its scales: Convergent evolution of the molluscan scleritome

Radiation of dramatically disparate forms among the phylum Mollusca remains a key question in metazoan evolution, and requires careful evaluation of homology of hard parts throughout the deep fossil record. Enigmatic early Cambrian taxa such as Halkieria and Wiwaxia (in the clade Halwaxiida) have been proposed to represent stem-group aculiferan molluscs (Caudofoveata+Solenogastres+Polyplacophora), as complex scleritomes were considered to be unique to aculiferans among extant molluscs. The 'scaly-foot gastropod' (Neomphalina: Peltospiridae) from hydrothermal vents of the Indian Ocean, however, also carries dermal sclerites and thus challenges this inferred homology. Despite superficial similarities to various mollusc sclerites, the scaly-foot gastropod sclerites are secreted in layers covering outpockets of epithelium and are largely proteinaceous, while chiton (Polyplacophora: Chitonida) sclerites are secreted to fill an invaginated cuticular chamber and are largely calcareous. Marked differences in the underlying epithelium of the scaly-foot gastropod sclerites and operculum suggest that the sclerites do not originate from multiplication of the operculum. This convergence in different classes highlights the ability of molluscs to adapt mineralized dermal structures, as supported by the extensive early fossil record of molluscs with scleritomes. Sclerites of halwaxiids are morphologically variable, undermining the assumed affinity of specific taxa with chitons, or the larger putative clade Aculifera. Comparisons with independently derived similar structures in living molluscs are essential for determining homology among fossils and their position with respect to the enigmatic evolution of molluscan shell forms in deep time.

Data Center Energy Demand: what got us here won't get us there!

Given environmentalism's rising tide and increasing energy prices and IT workloads, architects must determine whether they can continue designing systems without considering energy and power efficiency.

CNN Interactive just got more interactive

Interactive gallery installation which playfully re-contextualised online news feeds from CNN’s website with a soundtrack of found music in order to comment on an online environment where 'serious' news and trivial 'infotainment' often occupy the same space. ‘CNN Interactive just got more interactive’ aimed to investigate the balance between information and ‘info-tainment’ on the web. It demonstrated how the authority and presence of global news corporations online could be playfully subverted by enabling the audience to add a variety of emotively titled soundtracks to the monolithic CNN Interactive website. The project also explored how a work could exist dually as website and gallery installation. ‘CNN interactive’ contributes to the taxonomy of new media art as a new form of contemporary art. One of the first examples in the world of a gallery installation using live Internet data, it is also one of the first attempts in a new media art context to address how individuals respond to and comprehend the changed nature of the news as an immediate phenomenon as relayed by network communications systems. 'CNN interactive’ continues Craighead and Thomson’s research into how live digital networked information can be re-purposed as artistic material within gallery installation contexts but with specific reference to online-international news events, rather than arbitrary data sources (see e-poltergeist, output 1). ‘CNN Interactive’ was commissioned by Tate Britain for the exhibition ‘Art and Money Online’. This was the first gallery exhibition in Tate Britain featuring work that utilised and explored new media as an artistic area, and the first work commissioned by the Tate to operate simultaneously as an online gallery artwork. Selected reviews and citations include ‘Digital Art’ by Christiane Paul, 2003; ‘Internet Art: The Online Clash of Culture and Commerce’ by Julian Stallabrass. (2002); ‘Thomson & Craighead’ by Lisa Le Feuvre for Katalog Journal of Photography and Video, Denmark. All work is developed jointly and equally between Craighead and her collaborator, Jon Thomson, (Slade).
