One determinant of the success of a retail outlet is its location. The location strategies adopted by many retailers of convenience products, including those marketing groceries, have been based upon the principle of siting stores away from competition. Recent moves by leading grocery retailers to develop out of town and other sites jointly, where they would trade side by side, mean that methods are needed to appraise the selection of location partners to supplement or replace traditional, spatial analyses. A method based on similarity of image and cross-shopping behaviour is proposed and tested on two substantial data bases. A concept, drawn from theory on brand switching, that customers would treat outlets seen as similar in a similar way, is found not to apply to source switching. Source switching behaviour is found instead to vary with the source itself, according to two distinct patterns. In one, shoppers cross shop more to retailers perceived to be similar; in the other, shoppers cross shop more to retailers perceived to be different. The strategies currently adopted by four grocery retailers in joint site development are appraised against the model of source switching that can be defined from these patterns. Some location alliances are predicted to be potentially more valuable to one partner than another both in the short and long term. The anomalies identified in the selection of location partners are analysed by reference to concepts drawn from the literature on co-operation. Two different types of relationship exist between the various retail partners; a longer term alliance at each site and shorter co-operation between head offices. It is suggested that the nature of the second could prejudice the outcome of the first. 相似文献

Abstract Rural women have difficulty finding good jobs. Ownership of small businesses offers an alternative but the sales and income of women-owned firms are significantly lower than those of men-owned firms. Compared with men, women owners are more likely to operate smaller and newer businesses; however, these differences do not completely account for the gap in gross sales between men- and women-owned businesses. The strongest influences on business success are firm size, corporate status, and industrial sector. Though significant, the owner's gender is less important than these organizational characteristics. The factors influencing success of small businesses generally are the same for men- and women-owned businesses. More research on business networks and the start-up phase of small businesses is necessary for a better understanding of the sources of gender differences in success. 相似文献

The EM algorithm is a popular method for maximizing a likelihood in the presence of incomplete data. When the likelihood has multiple local maxima, the parameter space can be partitioned into domains of convergence, one for each local maximum. In this paper we investigate these domains for the location family generated by the t-distribution. We show that, perhaps somewhat surprisingly, these domains need not be connected sets. As an extreme case we give an example of a domain which consists of an infinite union of disjoint open intervals. Thus the convergence behaviour of the EM algorithm can be quite sensitive to the starting point. 相似文献

This paper presents empirical evidence that an individual's decision to drive while drunk is negatively affected by the expected full price of driving drunk. The analysis uses a unique data set containing information on self-reported drunk driving matched to state-level drunk driving policies as well as to state excise taxes on beer. These are hypothesized and found to affect drunk driving. Further, we find interesting racial differences but surprisingly small differences by gender in the effect of socioeconomic and policy variables on drunk driving propensities. 相似文献

Examining concepts about work and love can help people increase their career success and life satisfaction. Career counselors may initiate this examination by eliciting clients' concepts about work and love. After hearing a client's ideas about work and love, counselors can compare this personal meaning to the social meaning of work and love. When this comparison reveals dysfunctional beliefs about work and love, counselors can link these beliefs to their client's career concerns. Such a linkage typically provokes a cognitive dissonance that motivates clients to modify their beliefs. Counselors can facilitate meaning modification by using client-centered and social influence techniques. 相似文献

A training project in a northern Canadian community providedan opportunity to examine participatory planning approachesand the meaning of work in First Nations communities. Focusgroups conducted three years after the unsuccessful interventionof a community economic development (CED) project suggest thatcomplex factors such as lack of support from community leadersand rate of pay for workers determine whether CED is alwaysappropriate in northern, First Nations contexts. 相似文献
