Coopetition (collaboration between competitors) can facilitate product innovation, but there is still debate about how it is suited to radical or incremental innovation. This paper argues that the early and later phases of coopetitive new product development (NPD) pose different benefits and risks for the innovation types. Building on the tensions approach to value creation and appropriation, we develop a series of hypotheses on the role of coopetition in NPD alliances and focal firm's innovation output. The hypotheses are tested on a quantitative data set of 1049 NPD alliances in the German medical and machinery sectors. The results show that, while coopetition is advantageous for incremental innovation in both pre‐launch and launch phases, radical innovation benefits from coopetition in the launch phase only.  相似文献

Intuitive Toxicology: Expert and Lay Judgments of Chemical Risks   总被引:2,自引:0,他引:2  
Human beings have always been intuitive toxicologists, relying on their senses of sight, taste, and smell to detect harmful or unsafe food, water, and air. As we have come to recognize that our senses are not adequate to assess the dangers inherent in exposure to a chemical substance, we have created the sciences of toxicology and risk assessment to perform this function. Yet despite this great effort to overcome the limitations of intuitive toxicology, it has become evident that even our best scientific methods still depend heavily on extrapolations and judgments in order to infer human health risks from animal data. Many observers have acknowledged the inherent subjectivity in the assessment of chemical risks and have indicated a need to examine the subjective or intuitive elements of expert and lay risk judgments. We have begun such an examination by surveying members of the Society of Toxicology and the lay public about basic toxicological concepts, assumptions, and interpretations. Our results demonstrate large differences between toxicologists and laypeople, as well as differences between toxicologists working in industry, academia, and government. In addition, we find that toxicologists are sharply divided in their opinions about the ability to predict a chemical's effect on human health on the basis of animal studies. We argue that these results place the problems of risk communication in a new light. Although the survey identifies misconceptions that experts should clarify for the public, it also suggests that controversies over chemical risks may be fueled as much by limitations of the science of risk assessment and disagreements among experts as by public misconceptions.  相似文献

Abstract

This article explores visual discourses about over-40 and over-50 femininities that emerge from women’s own Instagram accounts. It analyses women’s visual and textual rhetoric of what over-40 and over-50 looks like, and whether it could interrupt the ageist, sexist, and body-normative discourses of female ageing and visibility. Intertextual visual discourse analysis of images, captions, and hashtags reveals two dominant themes (fitness and fashion) and two repeating rhetorical elements (motherhood and self-sufficiency) through which women make themselves visible as over-40/50. A few explicitly subversive discourses (i.e., over-40 fatshion account) exist, but a discourse of a healthy, fit, fashionable, independent, self-sufficient, and happy mother over-40/50 is prevalent. It easily lends itself to being interpreted as an insidious reproduction of post-feminist ideology, but I argue that there are moments of critique and subversion within. Thus, a reparative reading that acknowledges moments of disconnect from the discourse that normalizes ageing women’s limited or non-existent visibility is offered.  相似文献

Hohmeyer K, Wolff J. A fistful of euros: is the German one‐euro job workfare scheme effective for participants? Welfare reforms have constituted a major policy issue in many OECD countries in recent decades. In Germany, a major reform in 2005 emphasised the activation of welfare recipients and introduced a workfare programme –‘One‐Euro Jobs’– on a large scale. In the present study, the impact of one‐euro jobs on the employment prospects of different groups of participants was estimated. The analysis was conducted on a large sample of welfare recipients using propensity score matching. The sample of one‐euro job participants and other welfare recipients was drawn from administrative records comprising all those who started their participation in the programme in early 2005. Our results showed that participation slightly improved the medium‐term employment prospects for women but not for men. Participation reduced the employment rate of participants younger than 25 years but raised it for some of the older participant groups. In conclusion, one‐euro jobs are effective for participants who have been jobless for several years but ineffective for participants who were recently employed.  相似文献

Drawing on the work of Emile Durkheim ([1912] 1995) and Rodney Stark (2001 Stark, Rodney. 2001. Gods, Rituals, and the Moral Order. Journal for the Scientific Study of Religion, 40(4): 619636. [Crossref], [Web of Science ®] [Google Scholar]) as well as research on the anti-ascetic thesis and reference group theory, we formulate a series of hypotheses regarding the effects of church attendance and importance of religion on adolescents' moral beliefs about marijuana use, getting drunk, hitting, and property offenses. The results of our study suggest that moral beliefs are more consistently and strongly related to importance of religion than to church attendance. Furthermore, much of the effect of church attendance on moral beliefs is mediated by importance of religion. Finally, we find evidence that importance of religion moderates (interaction) the effect of church attendance on moral beliefs. When adolescents believe religion is important, frequent church attendance further strengthens their moral beliefs. On the other hand, when adolescents believe religion is not important, frequent church attendance may actually reduce moral beliefs.  相似文献

Recently C. Czymara and A. Schmidt-Catran published in this journal (KZfSS 2016 (2)) a factorial Survey-Experiment to contribute to the current debate on the inflow of refugees in Germany. The authors concluded from their Survey-Experiment that in particular highly qualified immigrants who show little culture distance should get accepted in Germany, while for instance Muslim immigrants would be more strongly rejected. In this comment it is argued that authors’ results probably suffered from a strong confounder bias. The employed experimental design also allows for a lot of alternative interpretations. Therefore, readers of the original article or further users of the data should be more cautious when interpreting the results.  相似文献

In the USA, the largest generation, the Baby Boomers, is currently retiring and increasingly drawing from Old Age Social Security. In this context, young generations are said to be disadvantaged: they have to support a growing number of pensioners while expecting much lower pensions themselves. Drawing on 14 original semi‐structured interviews with young US citizens aged 2036, this study analyzes the moral economy of intergenerational redistributiondefined as normative beliefs and justifications of a just distribution of contributions and benefits between generations. The qualitative content analysis resorts to the four constituent institutional principles of intergenerational redistribution: deservingness (being qualified to receive support), reciprocity (mutual support between generations), equity (relation between in‐ and outputs for one generation) and equality (corresponding conditions for different generations). The first main finding is that the young hold multiple normative beliefs in favour of intergenerational redistribution. The second main finding is that different normative beliefs and justifications can compensate for feelings of injustice attributable to the consequences of an ageing society. The qualitative findings' contributions to the field of study that is dominated by quantitative studies are concluded. Implications for public support for intergenerational redistribution in the ageing society of the USA and other countries are discussed.  相似文献
