Finding an efficient method for sampling micro- and small-enterprises (MSEs) for research and statistical reporting purposes is a challenge in developing countries, where registries of MSEs are often nonexistent or outdated. This lack of a sampling frame creates an obstacle in finding a representative sample of MSEs. This study uses computer simulations to draw samples from a census of businesses and non-businesses in the Tshwane Municipality of South Africa, using three different sampling methods: the traditional probability sampling method, the compact segment sampling method, and the World Health Organization's Expanded Programme on Immunization (EPI) sampling method. Three mechanisms by which the methods could differ are tested, the proximity selection of respondents, the at-home selection of respondents, and the use of inaccurate probability weights. The results highlight the importance of revisits and accurate probability weights, but the lesser effect of proximity selection on the samples' statistical properties. 相似文献

The current paper extends previous results on Hodrick–Prescott (HP) filtering and shows that it is possible to implement the judgement-augmented, or restricted, HP filter within the state-space framework. The implementation entails augmenting the vector of measurements and altering one of the system matrices of the state-space model for the HP filter. Restrictions can thereby be incorporated in the HP filter, making, e.g., estimation more accessible. An application to US GDP gap estimation illustrates how the restricted filter could be usefully applied in an empirical macroeconomic setting. 相似文献

Validation of Cohen's CAD scale was attempted on a sample similar to that used in the scale's original development. Results
were not in accord with the underlying theory. This prompted an attempt to refine the CAD instrument by deletion of ineffective
items. The revised scale was examined for reliability and validity. Results were sufficiently weak to suggest that marketers
should have diminished confidence in applying CAD as a measure of interpersonal orientation and should initiate development
of other approaches for personality assessment. 相似文献

This paper develops the concept of user image and then reports on an empirical test and appliation of the concept. User image
is defined as the image held of users of a product or service. This concept is supplemental to other conceptualizations of
image (e.g., self-image or ideal self-image). It was hypothesized that users and non-users, while demographically similar,
would hold differentimages of users of mass transportation. That hypothesis was supported. Implications for market segmentation promotions are drawn. 相似文献

With companies becoming more cost conscious the need for a more effective method of measuring the Return on Advertising is becoming more crucial. Previous attempts at measuring the return on advertising have focused on measuring either the sales effect or the communicative effect of an advertising campaign. However, both methods of measurement leave something to be desired and yet both techniques have strong points. This article proposes that one should synthesize the best elements of both measurement techniques into an objective design that will enable the practitioner to determine his ROA. 相似文献

Using the concept of external organizational commitment (EOC), survey data from 312 logistics service provider (LSP) implants are used to test a model of the determinants of implant level of commitment to their host firm and the consequences of such commitment to the LSP. The results show that both inter-organizational outcome and task interdependence affect implant perceptions of the degree to which they are supported by their host organization. Perceived organizational support by the host organization, in turn, was found to be positively related to implant commitment to their host organization, which was positively related to LSP operation-level performance. 相似文献

The significant growth in geotourism across all continents over the past two decades has created a strong demand for more creative, robust and systematic approaches to assessing the geotourism potential of natural areas, for identifying suitable sites of geological interest and providing comprehensive frameworks for management. We investigate a range of spatial data-sets using remote sensing analysis tools as well as geographic information systems (GIS) to complement field-derived data and allow for comprehensive analysis of combined data-sets. Such an approach allowed the creation of a spatial geological data base which can be assessed against access and management criteria, including environmental factors and risks. We used the relatively data-rich example of Rottnest Island in the south-west region of Western Australia to demonstrate the opportunities for future geotourism project development. 相似文献
