Berlin Fashion Week：An Inspiring Blend of Genres and Formats

The sheer numbers are impressive：since it opened its doors for the very first time in January 2003,Berlin Fashion show has experienced steady growth.Berlin Fashion week from July 8th to14th was another milestone in this range of growths figures：More than 200,000professional visitors were attracted by over 200 events, 100 of which were fashion shows.     

Breast cancer risk perceptions and breast cancer worry: what predicts what?

This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed.     

Comparing linear and nonlinear forecasts for stock returns

We compare the out-of-sample performance of monthly returns forecasts for two indices, namely the Dow Jones (DJ) and the Financial Times (FT) indices. A linear and a nonlinear artificial neural network (ANN) model are used to generate the out-of-sample competing forecasts for monthly returns. Stationary transformations of dividends and trading volume are considered as fundamental explanatory variables in the linear model and the input variables in the ANN model. The comparison of out-of-sample forecasts is done on the basis of forecast accuracy, using the Diebold and Mariano test [J. Bus. Econ. Stat. 13 (1995) 253.], and forecast encompassing, using the Clements and Hendry approach [J. Forecast. 5 (1998) 559.]. The results suggest that the out-of-sample ANN forecasts are significantly more accurate than linear forecasts of both indices. Furthermore, the ANN forecasts can explain the forecast errors of the linear model for both indices, while the linear model cannot explain the forecast errors of the ANN in either of the two indices. Overall, the results indicate that the inclusion of nonlinear terms in the relation between stock returns and fundamentals is important in out-of-sample forecasting. This conclusion is consistent with the view that the relation between stock returns and fundamentals is nonlinear.     

Berufsbedingte Dermatosen bei Pflegenden

Ekzeme – eine h?ufig untersch?tzte Gefahr - Untersuchungen zeigen, dass die Lebensqualit?t durch berufsbedingte Hauterkrankungen genauso eingeschr?nkt wird wie durch einen Myokardinfarkt oder Schlaganfall. Das ist für Pflegende deshalb so bedeutsam, weil gerade in Pflegeberufen Kontakt zu potenziell Allergie ausl?senden Stoffen besteht.     

A critical review of empirical research on open innovation adoption

The open innovation approach has been one of the most discussed topics in innovation management literature in the 2000s. Over the past few years, academic publications on open innovation have increased substantially. This paper attempts to summarize and review the state-of-the-art of empirical open innovation research and develop new opportunities for open innovation research in the future. In order to make the papers more comparable, a clear focus on large-scale quantitative-oriented studies was set. From a total of 282 documents, 30 studies were analyzed in detail along four key dimensions: Firstly, different methods of measuring open innovation adoption are compared. Then, the level of open innovation adoption is analyzed on a general basis. Thirdly, the level of adoption is compared at the level of the open innovation mode (inbound and outbound). Finally, the study results regarding the variables that influence open innovation adoption are compared and conclusions for future research directions are drawn.     

Einnahmen- und ausgabenseitige Multiplikatoren der deutschen Volkswirtschaft

Theoretically based on the Haavelmo theorem, this study analyses the economic effects that increasing public expenditure or reducing public income have on the gross domestic product of Germany, with the help of two medium-sized macro-econometric models, the RWI business cycle model and the Econometric Model of the German Economy. The major finding is that most of the public revenue multipliers are considerably lower than most of the public spending multipliers. However, both the dimension and the time course of the effects are a function of the specific kind of politico-economic measures taken by the government.     

The Tipping Point of Design: How Product Design and Brands Interact to Affect Consumers’ Preferences

Existing research on product design has demonstrated the importance of aesthetics in generating favorable consumer responses. However, the literature has only recently begun to explore if and to what extent the impact of product design is influenced by brand strength. Whereas some research indicates that strong brands may benefit less strongly from aesthetically attractive designs, other research suggests that attractive designs are more persuasive when they are paired with a strong brand. In this research, these two competing predictions were tested through three studies with German car buyers. In Study 1, participants were exposed to a fictitious car that was paired with a randomly chosen brand name. In Study 2, participants were presented with a set of existing cars and were asked to choose one. Both studies yield converging evidence and show that product design and brands interact in a positive fashion, suggesting that attractive designs exert a greater influence on consumers’ decision processes when they are accompanied by a strong brand. Study 3 extended these findings by demonstrating that strong brands only increase the impact of attractive designs when perceived risk is high but not when it is low.     

Evaluating transport user benefits and social surplus in a transport market—The case of the Norwegian ferries

The article first infers how consumer surplus in a market is linked to revenue under different assumptions about fare elasticity and when using different types of demand functions. This information is added to producer surplus in order to derive social surplus. The method, thus, produces a simple approach for authorities to assess social surplus in a market and its benefits to the users. A modified exponential demand function is applied to calculate consumer surplus and social surplus for 97 ferry services in Norway regulated by the state. The calculations are based on empirical data concerning ferry fare, revenue data at service level and reasonable assumptions about fare point elasticity for services covering different distances.In 2007, these services generated welfare for the users (consumer surplus) and the society (social surplus) amounting to about 5.8 billion NOK and 4.3 billion NOK, respectively. Consumer surplus and social surplus varied considerably amongst the services. Only 3 of the 97 services operate with positive profits and, hence, without subsidies. About 21 of the services contribute negatively to social surplus. Many of these unprofitable services are the only transport alternatives in rural areas and could be argued to continue operation according to politically decided regional measures. Implicitly, maintaining all these 21 services means that the welfare for the people in these areas is valued as up to four times greater than the welfare of the people in the rest of society.     

Strategic responses to market globalisation among advertising agencies

The advertising industry is undergoing major changes as markets and clients become more global. Using the integration-responsiveness framework and the transnational framework, it is apparent that advertising agencies have a high need to be simultaneously integrated and responsive. This paper reports on a series of depth interviews with international agency leaders intended to gain an assessment of both the extent to which their firms are responding to these important but conflicting needs and the appropriateness of the framework for understanding the strategic options available for ad agency management. The findings indicate that the agencies have tried to modify their strategies to accommodate both kinds of pressures. However, their success in this regard is questioned and other broader strategic concerns are considered.
