This study employs a qualitative Delphi panel to explore the perceptions of interactive agency executives on the adoption of online interactivity within the communication practices of companies of all trades in one of the biggest European media markets (Spain). The results highlight the serious challenges these practices pose to organizations and identify internal and external factors that affect the decision-making process. The study argues that actors’ definitions of interactivity are crucial in shaping Public Relations 2.0.  相似文献

We evaluated the richness, composition and abundance of bird communities in three urban forests of Mediterranean France during winter and spring. The urban forests differed in size, composition, structure, age of vegetation, and location relative to the city centre. Estimated species richness across all three urban forest parks was 45 species. Twenty six (26) species were recorded in both winter and spring, whereas ten species were recorded only in spring, and six were recorded only in winter. Distribution, turnover, and type of bird foraging guild were related to characteristics of each urban forest and season. During spring migration, more species were recorded in sampling units (250?×?250 m) within the largest and most natural urban forest located in the outskirts of Montpellier, whereas during winter, more species were recorded in the most urbanized park (i.e., a botanical garden dominated by exotic vegetation), which was located in the city centre. Insectivorous birds were more abundant in winter, whereas seedeaters associated with wooded habitats were recorded more frequently in spring. Our results suggested that different kinds of urban forests are important modulators of urban bird communities and they are necessary to maintain the diversity of migratory and resident birds as well as increasing the environmental quality of urban areas.  相似文献

This study investigates the degree of regionalization of UK exporters. The firm-level findings, based on an original set of primary data of 356 UK exporters, are contrasted with the UK national trade flows as well as with the geographic spread of the UK, European and the world’s largest MNEs. The analysis produced consistent findings of regionalization regardless of the classification thresholds or sales matrices employed. The findings also imply that country-level data supports the firm-level findings of regionalization. While the analysis presents relatively strong corroborating evidence of regionalization of UK exports, it also indicates that UK exporters might be more multi-regional and global oriented than previously thought.  相似文献

We propose a new goodness-of-fit test for normal and lognormal distributions with unknown parameters and type-II censored data. This test is a generalization of Michael's test for censored samples, which is based on the empirical distribution and a variance stabilizing transformation. We estimate the parameters of the model by using maximum likelihood and Gupta's methods. The quantiles of the distribution of the test statistic under the null hypothesis are obtained through Monte Carlo simulations. The power of the proposed test is estimated and compared to that of the Kolmogorov–Smirnov test also using simulations. The new test is more powerful than the Kolmogorov–Smirnov test in most of the studied cases. Acceptance regions for the PP, QQ and Michael's stabilized probability plots are derived, making it possible to visualize which data contribute to the decision of rejecting the null hypothesis. Finally, an illustrative example is presented.  相似文献

The purposes of this study were to extend the research conducted by Muehlenhard and her colleagues (e.g., Muehlen‐hard & Hollabaugh, 1988) on token resistance to sex and to consider a second form of sexual miscommunication, consent to unwanted sex. We examined the incidence of these forms of sexual miscommunication among both women and men and in three different cultures: the United States, Russia, and Japan. Survey data were collected from 1,519 unmarried college students (970 from the U.S., 327 from Russia, and 222 from Japan). Contrary to the stereotype that only women engage in token resistance to sex, men also reported that they had been in situations in which they had said no to sex while desiring it. In the U.S. only, a greater proportion of men than women have engaged in token resistance to sex. Rates for consent to unwanted sex also varied by gender and culture. American women had the highest rate of consent to unwanted sex. The importance of collecting cross‐cultural data on sexuality and intimacy is discussed.  相似文献

Precarious employment is a serious social problem, especially in those countries, such as Italy, where there are limited benefits from social security. We investigate this phenomenon by analysing the initial part of the career of employees starting with unstable contracts for a panel of Italian workers. Our aim is to estimate the probability of getting a stable job and to detect factors influencing both this probability and the duration of precariousness. To answer these questions, we use an ad hoc mixture cure rate model in a Bayesian framework.  相似文献

This study compares words and gestures produced in a controlled experimental setting by children raised in different linguistic/cultural environments to examine the robustness of gesture use at an early stage of lexical development. Twenty-two Italian and twenty-two Japanese toddlers (age range 25?C37?months) performed the same picture-naming task. Italians produced more spoken correct labels than Japanese but a similar amount of representational gestures temporally matched with words. However, Japanese gestures reproduced more closely the action represented in the picture. Results confirm that gestures are linked to motor actions similarly for all children, suggesting a common developmental stage, only minimally influenced by culture.  相似文献
