From Service to Experience: Understanding and Defining the Hospitality Business
Failure adequately to define or understand hospitality as a commercial phenomenon has created a fragmented academic environment and a schizophrenia in the industry that has the potential to limit its development as a global industry. This article suggests that, by redefining hospitality as behaviour and experience, a new perspective emerges that has exciting implications for the management of hospitality businesses. A framework to describe hospitality in the commercial domain is proposed. This framework suggests a focus on the hostâguest relationship, generosity, theatre and performance, âlots of little surprisesâ, and the security of strangers â a focus that provides guests with experiences that are personal, memorable and add value to their lives
Evidence for direct control of eye movements during reading.
It is well established that fixation durations during reading vary with processing difficulty, but there are different views on how oculomotor control, visual perception, shifts of attention, and lexical (and higher cognitive) processing are coordinated. Evidence for a one-to-one translation of input delay into saccadic latency would provide a much needed constraint for current theoretical proposals. Here, we tested predictions of such a direct-control perspective using the stimulus-onset delay (SOD) paradigm. Words in sentences were initially masked and, upon fixation, were individually unmasked with a delay (0-ms, 33-ms, 66-ms, 99-ms SODs). In Experiment 1, SODs were constant for all words in a sentence; in Experiment 2, SODs were manipulated on target words, while non-targets were unmasked without delay. In accordance with predictions of direct control, non-zero SODs entailed equivalent increases in fixation durations in both experiments. Yet, a population of short fixations pointed to rapid saccades as a consequence of low-level information at non-optimal viewing positions rather than of lexical processing. Implications of these results for theoretical accounts of oculomotor control are discussed
Microbiome diversity and metabolic capacity determines the trophic ecology of the holobiont in Caribbean sponges
Sponges are increasingly recognized as an ecologically important taxon on coral reefs, representing significant biomass and biodiversity where sponges have replaced scleractinian corals. Most sponge species can be divided into two symbiotic states based on symbiont community structure and abundance (i.e., the microbiome), and are characterized as high microbial abundance (HMA) or low microbial abundance (LMA) sponges. Across the Caribbean, sponge species of the HMA or LMA symbiotic states differ in metabolic capacity, as well as their trophic ecology. A metagenetic analysis of symbiont 16âS rRNA and metagenomes showed that HMA sponge microbiomes are more functionally diverse than LMA microbiomes, offer greater metabolic functional capacity and redundancy, and encode for the biosynthesis of secondary metabolites. Stable isotope analyses showed that HMA and LMA sponges primarily consume dissolved organic matter (DOM) derived from external autotrophic sources, or live particulate organic matter (POM) in the form of bacterioplankton, respectively, resulting in a low degree of resource competition between these symbiont states. As many coral reefs have undergone phase shifts from coral- to macroalgal-dominated reefs, the role of DOM, and the potential for future declines in POM due to decreased picoplankton productivity, may result in an increased abundance of chemically defended HMA sponges on tropical coral reefs
Fort Devens. Cold Climate, Energy-Efficient, Market-Rate Townhomes
In 2009, Mass Development issued an RFQ and subsequent RFP for teams to develop moderately priced high-efficiency homes on two sites within the Devens Regional Enterprise Zone. MassDevelopment, a Massachusetts agency that owns the Devens site (formerly Fort Devens Army Base, in Harvard, Massachusetts), set a goal of producing a replicable example of current and innovative sustainable building practices with a near-zero energy potential. Metric Development, as primary developer and construction manager, formed one of the successful teams that included CARB and Cambridge Seven Architects (C7A)
What is the optimal position of low-frequency words across line boundaries? An eye movement investigation
When displaying text on a page or a screen, only a finite number of characters can be presented on a single line. If the text exceeds that finite value, then text wrapping occurs. Often this process results in longer, more difficult to process words being positioned at the start of a line. We conducted an eye movement study to examine how this artefact of text wrapping affects passage reading. This allowed us to answer the question: should word difficulty be used when determining line breaks? Thirty-nine participants read 20 passages where low-frequency target words were either line-initial or line-final. There was no statistically reliable effect of our manipulation on passage reading time or comprehension despite several effects at a local level. Regarding our primary research question, the evidence suggests that word difficulty may not need to be accounted for when determining line breaks and assigning words to new lines
Contemporary 14C radiocarbon levels of oxygenated polybrominated diphenyl ethers (O-PBDEs) isolated in spongeâcyanobacteria associations

The definitive version was published in Marine Pollution Bulletin 62 (2011): 631-636, doi:10.1016/j.marpolbul.2010.12.022.Considerable debate surrounds the sources of oxygenated polybrominated diphenyl
ethers (O-PBDEs) in wildlife as to whether they are naturally produced or result from
anthropogenic industrial activities. Natural radiocarbon (14C) abundance has proven to
be a powerful tool to address this problem as recently biosynthesized compounds contain contemporary (i.e. modern) amounts of atmospheric radiocarbon; whereas
industrial chemicals, mostly produced from fossil fuels, contain no detectable 14C.
However, few compounds isolated from organisms have been analyzed for their
radiocarbon content. To provide a baseline, we analyzed the 14C content of four OPBDEs.
These compounds, 6-OH-BDE47, 2â-OH-BDE68, 2â,6-diOH-BDE159, and a
recently identified compound, 2â-MeO-6-OH-BDE120, were isolated from the
tropical marine sponges Dysidea granulosa and Lendenfeldia dendyi. The modern
radiocarbon content of their chemical structures (i.e. diphenyl ethers, C12H22O)
indicates that they are naturally produced. This adds to a growing baseline on, at least,
the sources of these unusual compounds.The project described was supported in part by Grant Numbers NA16RU1496 and

Genetics and Pathogenesis of Feline Infectious Peritonitis Virus
Feline coronavirus (FCoV) is endemic in feral cat populations and cat colonies, frequently preceding outbreaks of fatal feline infectious peritonitis (FIP). FCoV exhibits 2 biotypes: the pathogenic disease and a benign infection with feline enteric coronavirus (FECV). Uncertainty remains regarding whether genetically distinctive avirulent and virulent forms coexist or whether an avirulent form mutates in vivo, causing FIP. To resolve these alternative hypotheses, we isolated viral sequences from FCoV-infected clinically healthy and sick cats (8 FIP cases and 48 FECV-asymptomatic animals); 735 sequences from 4 gene segments were generated and subjected to phylogenetic analyses. Viral sequences from healthy cats were distinct from sick cats on the basis of genetic distances observed in the membrane and nonstructural protein 7b genes. These data demonstrate distinctive circulating virulent and avirulent strains in natural populations. In addition, 5 membrane protein amino acid residues with functional potential differentiated healthy cats from cats with FIP. These findings may have potential as diagnostic markers for virulent FIP-associated FCoV
