Key drivers of consumer purchase of airline tickets: A cross-cultural analysis

2013

Abstract This paper considers drivers of online airline ticket purchasing behaviour, and analyses the influence of attitude, subjective norm and perceived behavioural control on such decisions in two cultures. A number of hypotheses are examined using a sample of online shoppers in Spain and The Netherlands. We find that perceived control, subjective norm and attitude positively influence airline tickets online purchase intention in Spain, but in the Netherlands attitude is the key driver.

Tick Bites - the View from Inside-Out

2009

The tick feeding process in humans and its effects on the host skin have been studied histologically on specimens of tick bites, some of which included the attached parasite, and on ticks extracted from lesions or caught in the wild. The specimens, included in paraffin, were stained with hematoxylin-eosin, orcein–Giemsa for elastic fibers, periodic acid-Schiff for polysaccharides, Weigert method for fibrin, Warthin-Starry stain for spirochetes, and Bodian’s method for nerve fibers. The mouthparts of the attached ticks were embedded in a cement cone, with the chelicerae and the hypostome lining the oral canal, while the basis capituli contained the pharynx with its anti-reflux valves, the hy…

How Tick Size Affects the High Frequency Scaling of Stock Return Distributions

2014

We study the high frequency scaling of the distributions of returns for stocks traded at NASDAQ market as a function of the tick-to-price ratio. The tick-to-price ratio is a measure of an effective tick size. We find dramatic differences between distributions for assets with large and small tick-to-price ratio. The presence of returns clustering is evident for large tick size assets. The statistical differences between large and small tick size assets appear to reduce at higher time scales of observation. A possible way to explain returns dynamics for large tick size assets is the coupling of returns with bid-ask spread dynamics. A simple Markov- switching model is able to reproduce the pro…

A lethal Tick-Borne Encephalitis (TBE) due to TBE virus in Sicily (Italy): A case of IgG+/IgM-response?

2018

Tick-borne encephalitis (TBE) is an important viral infection of the central nervous system with high morbidity and mortality. With the increase of tourism TBE is becoming a problem also outside endemic regions. Italy is considered a country with low incidence of TBE and geographically restricted to the central and north eastern part of the country. In the south of Italy there is no evidence of disease presence, but neither is there much evidence of its absence. We report our experience about a lethal case of meningoencephalitis with a single-phase clinical course of the disease likely due to TBEV infection in a 13-year-old man. This is the first report of an autochthonous case of TBE in Si…

Ērču encefalīts Latvijā un Norvēģijā

2015

Problēmas aktualitāte: Saslimstība ar ērču encefalītu pieaug Ziemeļeiropā un ir endēmiska Centrālajā un Austrumeiropā. Ir svarīgi izvērtēt profilaktiskos un ārstniecības aspektus šai nenotveramai slimībai. Darba mērķis: Bija salīdzināt ērču encefalīta prevelanci Norvēģijā un Latvijā un analizēt dažādas klīniskās izpausmes un ārstēšanu, lai to optimizētu un samazinātu pacientu slimnīcā pavadīto laiku. Materiāls un metodes: Retrospektīvs pētījums, kurā tika iekļauti stacionētie pacienti ar diagnozi ērču encefalīts no MSIS datu bāzes un no P.Stradiņa KUS slimības vēsturu arhīva 2009-2014.gadā un LIC arhīva 2014.gadā. Pacientu vestures tika analizētas atbilstoši pētījumam radītajam formulāram a…

Tickle contagion in the somatosensory cortex

2021

AbstractThe cellular mechanisms of emotional contagion are unknown. We investigated tickle contagion and the underlying neuronal representations in rats. We recorded trunk somatosensory cortex activity of observer rats while they received tickling, audio-visual playback of tickling footage, and while they witnessed tickling of demonstrator rats. Observers vocalized, and showed “Freudensprünge” (“joy jumps”) during witnessing live tickling, while they showed little behavioral responses to playbacks. A fraction of trunk somatosensory neurons responded to both direct and witnessed tickling in action-specific manner. The correlation between direct and witnessed tickling responses increased towa…

More about the developing of invisible lipstick-contaminated lipmarks on human skin: The usefulness of fluorescent dyes

2006

At the present time fingerprints are one of the simplest, and most reliable means of identification. Increasingly, crime scene investigators look for palm, foot, ear or lip prints. With regard to lip prints, the use, very common today, of protective or permanent lipsticks allow the production an invisible lipmark (or invisible lipstick-contaminated lipmark) which is possible to develop. Some results have already been published about developers useful for different kinds of surfaces (both porous and non-porous) as well as those which are more efficient in case of old or recent prints. The latest studies are about the developing on human skin, and they prove the usefulness of lysochromes (spe…

2014

The contrast between self- and other-produced tickles, as a special case of sensory attenuation for self-produced actions, has long been a target of empirical research. While in standard wake states it is nearly impossible to tickle oneself, there are interesting exceptions. Notably, subjects awakened from REM (rapid eye movement-) sleep dreams are able to tickle themselves. So far, however, the question of whether it is possible to tickle oneself and be tickled by another in the dream state has not been investigated empirically or addressed from a theoretical perspective. Here, we report the results of an explorative web-based study in which participants were asked to rate their sensations…

EPIDEMIOLOGY OF BOUTONNEUSE FEVER IN WESTERN SICILY

1986

The distribution and prevalence of spotted fever group rickettsial infection in the ixodid dog tick Rhipicephalus sanguineus were found to occur at a rate of 19.7% with variation related to geographic and sociooccupational factors. A higher rate of infection was demonstrated in ticks removed from dogs associated with documented cases of boutonneuse fever. The results fit into available clinical and seroepidemiologic data on Rickettsia conorii infection in western Sicily.

Application of minidisk infiltrometer to estimate soil water repellency

2016

Soil water repellency (SWR) reduces affinity of soils to water resulting in detrimental implication for plants growth as well as for hydrological processes. During the last decades, it has become clear that SWR is much more widespread than formerly thought, having been reported for a wide variety of soils, land uses and climatic conditions. The repellency index (RI), based on soil-water to soil-ethanol sorptivity ratio, was proposed to characterize subcritical SWR that is the situation where a low degree of repellency impedes infiltration but does not prevent it. The minidisk infiltrometer allows adequate field assessment of RI inherently scaled to account for soil physical properties other…
