关键词： 传统文化   《拿来主义》   情人节   圣诞节  

摘要： 鲁迅先生曾在《拿来主义》中犀利地抨击了国人对传统文化“大方送出，不点评求索取”的错误态度，指出“我们要运用脑髓，放出眼光，自己来拿”。几十年过去了，当西方的圣诞节和情人节在中国日益红火、声势浩大之时，先生深刻又极具预见性的批判，瞬间具有了现实的深意。

关键词： Tourists' expenditure   Mental budget   Shopping plans   Christmas market   Heckman estimator with ordered-Probit selection rule  

摘要： The present paper investigates the determinants of tourists' expenditure by categorizing tourists based on their mental budgets. Individuals can be divided into three categories based on the difference between their mental budget and actual expenditure: underspenders, on-budget spenders, and over spenders. Estimation of the empirical model is performed based on data collected through a survey of visitors to the Christmas Market in Merano, Italy during Advent in 2011. The estimation is performed with the Heckman estimator, ordered probit selection rule, and linear regression. We find that the spending patterns of visitors belonging to the three identified categories differ significantly. Analyzing visitors' expenditure based on the proposed categorization allows us to identify category-specific factors and develop management strategies for each category. The managerial and theoretical implications of the results are discussed. (C) 2017 Elsevier Ltd. All rights reserved.

关键词： Yule tree   binary search tree   branching random walk   lattice case  

摘要： For a particular case of a branching random walk with lattice support, namely the Yule branching random walk, we prove that the distribution of the centred maximum oscillates around a distribution corresponding to a critical travelling wave in the following sense: there exist continuous functions t bar right arrow a(t) at and x bar right arrow phi(x) such that: lim(t ->+infinity) sup (x is an element of R) vertical bar P((X) over bar (t) <= a(t) + x) - (phi) over bar (x - {a(t) + x})vertical bar = 0, where {x} = x - left perpendicular x right perpendicular and X(t) is the height of the Yule tree. We also shows that similar oscillations occur for E (f ((X) over bar (t)-a(t))), when f is in a large class of functions. This process is classically related to the binary search tree, thus yielding analogous results for the height and for the saturation level of the binary search tree. (C) 2016 Wiley Periodicals, Inc.
