The article deals with the implicit premises of two hypotheses about the relationship between public relations and journalism and rejects them in part. Especially the hypothesis that public relations determines the media agenda unnecessarily implies basic assumptions which are either too restrictive or ideologically motivated. Moreover, there is less empirical support for this hypothesis than its popularity among communication scientists would suggest. In the studies examined, the percentage of subsidized stories in the press varied between 18 to 65. The model of intereffication describes the relationship between PR and journalism more adequately, but it does not work, in contrast to its claims, at a functional systems level. To illustrate the heuristic potential of both hypotheses, the Westley/MacLean model for communications research is adapted to the transmission of PR messages via the mass media.  相似文献

After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft, shipping or trucks. The customers are the failures, and their service time is the time that goes from the instant at which they occur till they are completely repaired. The failing repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application, models of Carrillo (1991) and Ferreira (1996) are considered, improved and completed. The theory is illustrated with a numerical example.  相似文献

This paper investigates the impact of international investors on the quality of financial accounting information in Russia. I hypothesize that international stock ownership leads to enhanced quality and adoptions or intentions to adopt IFRS by Russian firms. Data was gathered through face-to-face interviews with 100 Saint-Petersburg firms randomly selected from the INFOWAVE data base. The results are consistent with the hypotheses.  相似文献

Do new school types focusing on practical and business‐related knowledge lead to increased economic performance? To analyse this question, this article examines the introduction of two types of modern secondary education, the Gewerbeschule and its successor, the Realschule, in nineteenth‐century Bavaria. Since the opening of these schools is arguably endogenous—as it was mainly the large, prosperous cities that opened one—the estimated treatment effect capturing the economic influence of the Gewerbeschule/Realschule will lead to biased results. To alleviate this bias, propensity score matching is adopted to compare relatively similar counties with and without these schools. Using historical county‐level data on tax revenues, business formations, employment structure, and patent holdings, ordinary least squares regression analysis shows that the opening of a modern secondary school is in general positively associated with economic performance several years later.  相似文献

We analyse the relationship between public debt, economic growth and inflation in a group of 52 African economies between 1950 and 2012. The results indicate that the limits of public debt are negatively related to economic growth and exhibit, from a given level of debt, an inverted U behaviour regarding the relationship between economic growth and public debt. Briefly, the high levels of public debt are coincident with reduced rates of economic growth and rising levels of inflation. Our results for three specific geographical areas resemble those of the overall analysis, despite some differences. In North African countries, the growth rates of the gross domestic product (GDP) and inflation also show an inverted U behaviour as the ratio of public debt/GDP increases. The highest rate of economic growth is recorded when the ratio of public debt/GDP is below 30% of GDP and corresponds to an average inflation rate of 5.33%. An identical behaviour of the GDP growth rates and inflation also appears in Sub‐Saharan countries until the third interval (60–90%). However, the highest growth rate of the GDP and GDP per capita is registered when the public debt/GDP ratio is in the second interval (30–60%). For the countries of the Southern Africa Development Community, the highest average rate of economic growth (6.8%) is similar to North African countries, when the ratio public debt/GDP is below 30% of GDP, with an average inflation rate of 11%. A number of robustness analyses were performed and the great majority of them confirm the general analysis.  相似文献

The Inca heritage is intermingled in a long trajectory of histories, creations and revivals that have constantly contributed to the renewal of its imagery. This paper analyses an important Inca revival movement that has been crucial in the making and remaking of Southern Andean identities: Indigenismo Cusqueño (1905–1945). This Cuzco version of Indigenismo was a regionalist urban middle class movement that emerged at the turn of the 20th century. I analyse how these Indigenistas, or an elite of intellectual ‘legislators’ from Cuzco shaped the regional identity through the ‘recovery’ of an authenticity founded in the legacy of the ancient Empire. Four decades of the production of a heritage initiated a so-called ‘folklorisation’ process that led to the mobilisation of the peasant mass through the enactment of an ancient Inca ritual in 1944. By staging performances of identity and promoting wide participation, the Indigenistas aimed at promoting a ‘regionalist’ identity campaign, attracting tourism-related investments and transforming the Inca capital into the ‘cradle of Peruvianness’.  相似文献

Conservation volunteer tourism (VT) (or nature conservation expedition)‐related organisations can provide a meeting point for both tourists and field‐based scientists. Expedition leaders should be aware of the needs of the volunteer tourists that can be fulfilled through VT. It appears that the role of expedition leaders is central to the successful execution of the VT expedition. This study aimed to understand the expedition leaders' perceptions of VT, their perspective of the expectations of their volunteer tourists and their requirements of the volunteers, and assess how volunteers perform with regard to those requirements. The results suggest that there may be some differences in perceptions between leaders and volunteer tourists that may affect the success of the expedition.

Abstract

Progressing sustainable tourism requires both an innovative transition from “unsustainable” tourism and innovative research methods to develop theory and concepts for a sustainable tourism. While there are many ad hoc examples of initiatives, there are very few examples of firms systematically recording their medium-term evolutionary progress. This case study of an accommodation provider uses longitudinal data over 14 years, deductive and inductive methods, and comparison with other similar eco-friendly providers, to provide the first exploration of sustainability-oriented innovation by a firm attempting to make transitions. Findings show how important hindsight and insight are for continuous learning, and how broader community sustainability issues influence the owners’ worldviews. Both learning and changing views are required to support innovation. A Sustainability-oriented Service Innovation model is recommended, recognising the characteristics of a service industry where innovation can be an organic process led by humans for humans and consequently more fuzzy in its progress than the clearly defined steps that are suggested by previous research. This model seeks to assist researchers and practitioners to better measure innovative progress of service firms, and develop more relevant strategies to ease transitions towards sustainable business practices.  相似文献

The size and composition of our bin has changed over the years, as a result of the evolution of our way of living and our consumption habits. The wider range of goods now offered to consumers has resulted in significant augmentation of waste discarded in the form of packaging. The latter is estimated to represent about 30% by weight of total domestic waste. More than ever concerned about environmental issues, the public, alarmed by the media, has shown a strong interest in the problem of waste and waste management. Packaging is now felt as excessive, wasteful and bad for the environment, in particular plastic packaging since plastics are not as easily recycled as other materials. This paper, which includes the results of a consumer survey, brings to light the attitude and misconception of European consumers towards packaging and packaging materials and gives another insight into the problem.  相似文献
