Motivations for tourism adoption by vineyards worldwide: A literature review
Wine tourism has been increasingly implemented by wineries in several countries around the world. This article aims at identifying the motivations for wine tourism adoption by wineries around the world through a narrative bibliographic review. This paper includes an analysis of articles related to the subject taken from the Web of Science database. In this article, we identified the objectives, methods, and conclusions reached by authors, who researched wine tourism. The bibliographic survey based on the keywords “wine” and “tourism”, resulted, after refining it by reading titles and abstracts, in 20 articles. The results show that most wineries in the studied sample adopt wine tourism as a strategy to achieve marketing-related benefits. Also, some wineries are motivated by the competitive advantage, economic development and increasing demand for such service. It is concluded that wineries are increasingly seeking to adapt to current consumer demands. From the perception of the importance of service experience offered to the consumer, mainly in the product sale

Self-avoiding walks and connective constants in small-world networks
Long-distance characteristics of small-world networks have been studied by
means of self-avoiding walks (SAW's). We consider networks generated by
rewiring links in one- and two-dimensional regular lattices. The number of
SAW's was obtained from numerical simulations as a function of the number
of steps on the considered networks. The so-called connective constant,
, which characterizes the long-distance
behavior of the walks, increases continuously with disorder strength (or
rewiring probability, ). For small , one has a linear relation , and being constants dependent on the underlying
lattice. Close to one finds the behavior expected for random graphs. An
analytical approach is given to account for the results derived from numerical
simulations. Both methods yield results agreeing with each other for small ,
and differ for close to 1, because of the different connectivity
distributions resulting in both cases.Comment: 7 pages, 5 figure

Search for single top quarks in the tau+jets channel using 4.8 fb of collision data
We present the first direct search for single top quark production using tau
leptons. The search is based on 4.8 fb of integrated luminosity
collected in collisions at =1.96 TeV with the D0 detector
at the Fermilab Tevatron Collider. We select events with a final state
including an isolated tau lepton, missing transverse energy, two or three jets,
one or two of them tagged. We use a multivariate technique to discriminate
signal from background. The number of events observed in data in this final
state is consistent with the signal plus background expectation. We set in the
tau+jets channel an upper limit on the single top quark cross section of
\TauLimObs pb at the 95% C.L. This measurement allows a gain of 4% in expected
sensitivity for the observation of single top production when combining it with
electron+jets and muon+jets channels already published by the D0 collaboration
with 2.3 fb of data. We measure a combined cross section of
\SuperCombineXSall pb, which is the most precise measurement to date.Comment: 12 pages, 5 figure
