Like other broad disciplines in the media/communications field, communication science is characterized by rapid growth and increasing diversity and hence confusion. That also affects the discipline’s scholarly associations. So the German Association for Communication Science (Deutsche Gesellschaft für Publizistik- und Kommunikationswissenschaft, DGPuK), the largest German-speaking association in this field, conducted a survey among its members in early 2003. This article reports on the design and findings of this study, focusing on the perception and evaluation of the association and on the scholarly orientations (theoretic perspectives and methodologies) of its members. Various subgroups within the DGPuK diverge in their positions and opinions. This applies in particular to the less well represented research traditions and subdisciplines (as compared to the social-scientific mainstream), which tend to view the DGPuK as one-sided. Deviations also show for professionals working outside the academic field (as compared to DGPuK members from universities) and in part for older members and women. The findings not only give an up-to-date picture of the state of the DGPuK but also shed light on the situation and development of the discipline as a whole. 相似文献

Between 1984 and 1994, successive New Zealand governments—first of the left, then of the right—managed the most dramatic and comprehensive deregulation exercise of any OECD country in decades. What have been the effects of this on the labour market? 相似文献

In the exact sciences one distinguishes between the exactness of the estimate of a quantity, or the ‘accuracy’, and the exactness of the symbolic representation of the estimate, its ‘precision’. The significant-digits rule, the subject of the most elementary education in these disciplines, establishes a rough correlation between accuracy and precision. It is shown that many agricultural economists and statisticians are unsure about the proper representation of accuracy in writing. The accuracy of one particular statistic, net farm income in Canada, has been estimated using Theil's RMSE statistic. The results suggest that net farm income should be written with two or three digits only according to the significant-digits rule. The author recommends that the significant-digits rule generally be followed. Economy in communication and greater awareness of the nature and limitation of the empirical basis of our knowledge would be gained. Dans les sciences exactes une distinction précise est fait entre 1'exactitude de la mesure d'une quantité et la précision de la représentation symbolique de cette mesure. La règie des chiffres signicatifs, le sujet de l'enseignement le plus élémentaire en les sciences naturelles, établit une corrélation approximatif entre l'exactitude de la mesure et la précision de la représentation. Les économistes et les statisticiens rurales semblent être incertains sur la représentation de l'exactitude de la mesure das la communication écrite. L'exactitude d'un devis particulier - la revenu net agricole canadien - a été estimé en utilisant la statistique RMEC (la racine de la moyenne de l'erreur carré) de THEIL. Les resultats suggerent que cette statistique devrait être écrit avec seulement deux ou trois chiffres, suivant la règie des chiffres signicatifs, au lieu de l'écrire avec sept chiffres d'après I'usage courant. l'auteur voudrait conseiller que, à I-avenir, la règie des chiffres signicatifs soit utilisé dans toutes les publications de manière à encourager l'économie dans la communication et une conscience professionnelle plus grand de la nature des limitations de la base empirique de notre connaissance. 相似文献

In Flak/Schmid (1993) an outlier test for linear processes was introduced. The test statistic bases on a comparison of each
observation with a one-step predictor. It was assumed that an upper bound for the total number of outlierss
n is known, wheren denotes the sample size. The asymptotic distribution of the test statistic was derived under the assumption thats
n/n → 0 ands
n → ∞ asn → ∞. This note deals with the asymptotic behaviour of this quantity, ifs
n/n →p

Summary In the light of the probable market development of new multimedia products and services, domestic demand for media and communications goods in the year 2010 will be around three times its level at the start of the 1990s. The increase in private sector demand will be somewhat higher than general economic expansion, the rise in private household demand will be slightly higher than the growth of private consumption. This is, however, contingent on solutions being found by 1998 for the technical and regulatory questions that are as yet still unresolved. What is decisive for the pace at which the telecommunications infrastructure will develop is the degree of competitive and innovative pressure. German policy makers can contribute to this by ensuring that the (still publicly owned) Telekom AG sells off its cable TV networks. It would also seem important to restrict the time-consuming licensing procedure for broadcasting companies to programmes with a bearing on public opinion and to render the regulatory procedure more efficient by setting up a national body to perform this task.The number of employees in firms producing and distributing M&C technology will expand to a far lesser extent than domestic demand to the year 2010, largely due to productivity growth. Model calculations point to an increase of the order of 10% to around 2.1 million jobs. This means that the significant positive employment effects frequently forecast for the new M&C technologies can only come about if the potential for rationalisation inherent in these technologies is utilised throughout the economy in a rigorous fashion to raise efficiency and international competitiveness. Such competitive advantages can only be generated, however, if a broad-based application of the new multimedia is realised earlier than in Germany's leading competitors. 相似文献
