The argument in this paper rests on the assumption that the prime objective of any corporate activity must in some way be related to a profitability goal, however this may be measured, however this may be defined, and however this may be constrained by the relevance of a times-cale.
The paper makes some comments on the selection of a corporate objective or goal but mainly it considers the direct contribution that financial management can make to achievement of this goal. It distinguishes this from the accounting rôle which is more appropriately concerned with measuring and monitoring progress towards the goal. 相似文献

W. S. Simpkins 《The Australian journal of social issues》1971,6(3):194-201
The views of a sample of Australian teachers were obtained regarding the powers exercised by teachers and administrators in decisions relevant to internal school government. The teachers perceived themselves as playing a delegated-leadership role within the classroom and a subordinate role in decision areas external to classroom management. On the other hand, they expressed a desire to extend their delegated-leadership role to important matters concerning the instructional organization and administration of the school. The evidence suggested that teachers wished to change the perceived balance of power in schools in the direction of a more ‘democratic’ style of school government. 相似文献

Using an extremely rich data series, this paper traces trendsin America's most important problem from 1946 to 1976. Bothlong-term and short-term changes in public concern are charted.Additionally, the problem profiles of major sociodemographicgroups are analyzed. Changes in the problem concerns of thesegroups are also followed across time. 相似文献

The concept of consumer “loyalty” (i.e., preference for a particular store or brand) is intriguing to marketing scholars and practitioners. Research in this area would be enhanced by the acceptance of an operational measure of consumer loyalty. Loyalty appears to be a tri-dimensional concept; per cent of budget, allocated to the store or brand, amount of switching, and number of alternatives explored have been used to measure loyalty. Consequently, the authors propose a “loyalty index” which combines these three measures. An empirical test of the proposed index showed that the index did discriminate among degrees of consumer loyalty, and was related to consumer psychological characteristics in a manner similar to that of the generally used single measures of consumer loyalty. 相似文献

Understanding contemporary urban landscapes requires multiple sets of spatially and temporally compatible data that can integrate historical land use patterns and disturbances to land cover. This paper presents three principal methods: (1) core analysis; (2) historic mapping; and (3) gradient analysis, to link spatial and temporal data for urban ecosystems and applies their use in the Baltimore-Chesapeake region. Paleoecological evidence derived from the geochronology of sediment cores provides data on long-term as well as recent changes in vegetative land cover. This information, combined with contemporary vegetation maps, provides a baseline for conducting trend analyses to evaluate urbanization of the landscape. A 200-year historical land use database created from historical maps, census data, and remotely sensed data provides a spatial framework for investigating human impacts on the region. A geographic information system (GIS) integrates core analyses with historic data on land use change to yield a comprehensive land use and land cover framework and rates of change. These data resources establish the regional foundation for investigating the ecological components of an urban ecosystem. Urban-rural gradient analyses and patch analyses are proposed as the most appropriate methods for studying the urban ecosystem as they link ecological and social patterns and processes for varying degrees of urbanization. 相似文献
