What drives the adoption and consumption of green hotel products and services? A systematic literature review of past achievement and future promises

2021

The current study utilises the time-tested systematic literature review (SLR) method to identify and analyse 76 studies addressing the consumer adoption of green hotels. The results of the research profile analysis show that the literature on consumers' adoption and consumption of green hotel products and services is expanding and gaining more recognition from researchers working in Asian contexts, particularly China, Taiwan and India. Moreover, the qualitative thematic analysis yields four key themes, (a) consumer behaviour variables addressed, (b) antecedents and mediators of green hotel adoption, (c) moderators of the relationship and (d) methodological considerations, for which limitati…

ROCURONIO/SUGAMMADEX VS ROCURONIO/ NEOSTIGMINA NELLA CHIRURGIA BARIATRICA PER BYPASS

2013

Obiettivo. La chirurgia bariatrica è caratterizzata da un incre- mento di morbidità e mortalità post operatoria tre volte maggiore dei pazienti normopeso, in assenza di altri fattori di rischio. La decurarizzazione efficace, riduce il rischio di cura- rizzazione residua post operatoria, e le complicanze ad essa associate 1. Obiettivo del nostro studio è di valutare l’efficacia in termini di recupero dell’attività neuromuscolare all’accele- romiografia e in termini di ripresa clinicamente obiettivabile della Neostigmina vs Sugammadex. Materiali e metodi. Abbiamo arruolato 40 pazienti sottoposti a chirurgia bariatrica per bypass, suddivisi in due gruppi di età >18 anni, BMI >30 kg/m2, classe …

Shrinking language models by robust approximation

2002

We study the problem of reducing the size of a language model while preserving recognition performance (accuracy and speed). A successful approach has been to represent language models by weighted finite-state automata (WFAs). Analogues of classical automata determinization and minimization algorithms then provide a general method to produce smaller but equivalent WFAs. We extend this approach by introducing the notion of approximate determinization. We provide an algorithm that, when applied to language models for the North American Business task, achieves 25-35% size reduction compared to previous techniques, with negligible effects on recognition time and accuracy.

Quantum versus Probabilistic One-Way Finite Automata with Counter

2001

The paper adds the one-counter one-way finite automaton [6] to the list of classical computing devices having quantum counterparts more powerful in some cases. Specifically, two languages are considered, the first is not recognizable by deterministic one-counter one-way finite automata, the second is not recognizable with bounded error by probabilistic one-counter one-way finite automata, but each recognizable with bounded error by a quantum one-counter one-way finite automaton. This result contrasts the case of one-way finite automata without counter, where it is known [5] that the quantum device is actually less powerful than its classical counterpart.

Multiple Usage of Random Bits in Finite Automata

2012

Finite automata with random bits written on a separate 2-way readable tape can recognize languages not recognizable by probabilistic finite automata. This shows that repeated reading of random bits by finite automata can have big advantages over one-time reading of random bits.

Tally languages accepted by Monte Carlo pushdown automata

1997

Rather often difficult (and sometimes even undecidable) problems become easily decidable for tally languages, i.e. for languages in a single-letter alphabet. For instance, the class of languages recognizable by 1-way nondeterministic pushdown automata equals the class of the context-free languages, but the class of the tally languages recognizable by 1-way nondeterministic pushdown automata, contains only regular languages [LP81]. We prove that languages over one-letter alphabet accepted by randomized one-way 1-tape Monte Carlo pushdown automata are regular. However Monte Carlo pushdown automata can be much more concise than deterministic 1-way finite state automata.

Local automata and completion

1993

The problem of completing a finite automata preserving its properties is here investigated in the case of deterministic local automata. We show a decision procedure and give an algorithm which complete a deterministic local automaton (if the completion exists) with another one, having the same number of states.

Expression and possible functions of the cholinergic system in a murine embryonic stem cell line.

2007

The expression of a cholinergic system during embryonic development is a widespread phenomenon. However, no precise function could be assigned to it during early pre-neural stages and there are only few studies that document when it precisely starts to be expressed. Here, we examined the expression of cholinergic components in a murine embryonic stem cell line by RT-PCR, histochemistry, and enzyme activity measurements; the acetylcholine (ACh) content was measured by HPLC. We have demonstrated that embryonic stem cells express ACh, acetylcholine receptors, choline acetyltransferase (ChAT), acetyl- and butyryl-cholinesterase (AChE and BChE). Butyryl-cholinesterase (BChE) expression was highe…

Enzymatically hydrolyzed low-density lipoprotein modulates inflammatory responses in endothelial cells

2009

SummaryThere is evidence that low-density lipoprotein (LDL) is modified by hydrolytic enzymes,and that the product (E-LDL) induces selective production of interleukin 8 (IL-8) in endothelial cells. Since nuclear factor-kappaB (NF-κB) is a major regulator of IL-8 transcription, we studied its activation in endothelial cells treated with E-LDL. Unexpectedly,the modified lipoprotein not only failed to activate NF-κB, but completely blocked its activation by tumour necrosis factor-alpha (TNF-α) in EA.hy926-cells, as assessed by electrophoretic mobility shift assays and immunofluorescence. Inhibition occurred upstream of NF-κB translocation, as inhibitor of NF-κB- (IκB)-phosphorylation was suppr…
