An Initial Investigation of Integrating Innovation Diffusion Models for Drawing First‐time Visitors

Prior studies in the existing tourism literature have frequently emphasized the relatively expensive costs for drawing first‐time visitors. These studies, however, have largely failed to explain how to draw first‐time visitors to a destination. In other words, little was known regarding what destinations should do to attract first‐time visitors in an effective way. To provide more insights, this research investigated the impact of three diffusion models on attracting first‐time visitors. These models included an external influence model for impact of mass media, an internal influence model for impact of interpersonal communications, and a mixed model for impacts of both mass media and interpersonal communications. Assessing the model impact in a macroapproach for first‐time visitors to Hong Kong, empirical findings indicated that the mixed influence model provided the highest explanatory quality, with word‐of‐mouth being a dominant factor.     

论休闲经济研究的理论经济学意义

理论经济学走向科学化的历程至少有三重意蕴:数学化、符号化和心理学化,它直接导致对劳动时间的遮蔽和经济学的非人化.大众法定闲暇时间的增加和居民休闲生活的繁荣,放大了人性的复杂性,澄明了生活方式对于理论经济学的重要性,彰显财富之根--自由时间,从长远来看,迟早将孕育理论经济学的一场彻底革命,即由劳动时间根基转向自由时间根基.     

Tourists’ impulse buying behavior at duty-free shops: the moderating effects of time pressure and shopping involvement

This study investigates the consumer behavior of tourists at duty-free shops who experience different limitations on shopping than do consumers at general shopping malls. The target for sampling was outbound tourists who shopped in two hotel duty-free shops in Seoul, Korea. The final analysis used data from 343 respondents and the results revealed (1) the more positive the emotions felt by tourists, the more impulsive buying behavior occurs; (2) time pressure during shopping reinforces negative emotions, resulting in increased affective impulse buying; and (3) increased shopping involvement directly increases cognitive impulse buying.     

闲暇经济理论综述及最新进展

随着国外发达国家相继进入后工业化社会,闲暇经济理论尽管还远未成型,但已经成为国外经济研究的新兴课题,本文按照闲暇经济理论的发展历史和研究方向,从两个方向综述了该理论的内容,一是依据对不同类型闲暇时间的研究来进行综述,二是在此基础上从闲暇被引入进各类函数和经济系统的角度综述了相关研究的主要成果.     

应用轨迹灵敏度计算临界切除时间的新方法研究

文章提出了一种可以描述故障后系统稳定程度的灵敏度指标,根据系统稳定性逐渐恶化指标趋于零的特点,计算了系统部分参数的临界值;根据稳定指标与故障切除时间在一定范围内的良好线性关系,估算了系统故障临界切除时间;并在单机无穷大系统与10机典型新英格兰系统下进行验证,证明了该方法的正确性。

Sequential point estimation of normal mean under LINEX loss function

A sequential point estimation of the mean of a normal distribution is considered under LINEX loss function. The regret of sequential procedures are obtained. Furthermore, it is shown that a sequential procedure with the sample mean as an estimate is asymptotically inadmissible. An accerelated stopping time is also considered. Received: December 1999     

关于NBA赛程利弊因素的分析与评价模型

本文考虑球队间胜率、主场优势、休整时间三个因素来分析赛程对某一支球队的利弊。建立主场优势、休整时间同球队间胜率的变化量之间的多元线性回归模型:△Pij=β0+β1x1+β2x2+β3x3+β4x4+ε。通过赛程数字化方法得出某一球队的回归变量矩阵[x1、x2、x3、x4]及预测变量矩阵[△Pij],做回归分析得到回归系数并定义了数量指标评价赛程对球队的利弊,并给出了计算某一球队值的算法。     

Searching for synchrony

Authorities working on economic-crime investigation in Finland are trying to change their form of collaboration from the sequential passing of documents towards parallel, interorganizational collaboration: the on-line investigation of an ongoing crime. The synchronization of events and the outputs of various participants proved to be difficult in this emerging process. This new model of crime investigation also requires a new kind of time management. This article explores how the change is being constructed in everyday practice by examining three economic-crime-investigation cases. It is claimed that individual efforts to manage time allocation suffice only in terms of co-ordination of events. It is suggested that a successful shift to parallel, interorganizational collaboration requires more than the common marking of calendars. The object of the work and the forms of interaction should be taken as subjects of reflective negotiation. New kinds of collective time-management tools are needed in this effort.     

Production technologies in stochastic continuous time models

Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a large class of models some of which, however, have some undesirable features such as potentially negative output. This paper offers closed-form solutions for models which are just as tractable but do not suffer from these shortcomings.
