This field study examining the effects of organizational status and multimedia audio communications technology on communication patterns in business meetings confirms that high status group members verbally dominate discussions and have more control over the flow of the proceedings. However, it reveals a new and surprising finding: multimedia communications technology can in fact exaggerate status constraints in contrast to findings that there is no effect or an equalizing effect on status inequalities of text-based conferencing technology. It appears that in audio conferences, the lack of non-verbal cues that can aid turn-taking combined with (1) the participants' knowledge of the group's status hierarchy and (2) the tendency to compare oneself unfavourably to those of higher status, makes it more difficult for lower status individuals to contribute verbally to discussions than in face-to-face interactions. Such status constraints may have both positive and negative impacts on group communication effectiveness, these and implications for the design and implementation of multimedia communications technology are discussed. 相似文献

Henri Lefebvre's right to the city concept is increasingly used to challenge the development prerogatives associated with neoliberal development. These challenges are more common as gentrification becomes a global urban strategy. This article is an empirical investigation that examines competing claims to community legitimacy and authenticity in a conflict over gentrification in a Philadelphia neighborhood. This conflict emerged in Fishtown when long‐time established residents went head to head with upper‐income gentrifiers over the location of a casino in the neighborhood. Place‐based identities and the temporal connection individuals had to Fishtown contributed to the differences in perspectives on the costs and benefits of the casino and on the legitimacy of long‐time residents versus newcomers to be representative voices on behalf of Fishtown. The findings illuminate problems in applying the right to the city to neighborhood struggles when communities are divided over what constitutes a benefit to the community. The right to the city may not be a universal claim, particularly within a neoliberal urban context. 相似文献

The formation of sludge on the bottom of vats during cottage cheese manufacture was investigated. The sludge layer contained 4.23-8.11% of the casein originally present in the vat and was probably caused by agglutinins present in the skimmed milk. Homogenization of the skimmed milk before addition of starter reduced the agglutination of bacteria during the early stages of acid development and eliminated minor sludge formation. Curd yield was increased by up to 5% and average manufacturing time was reduced by 40 min following homogenization. 相似文献

Physical, Chemical and Sensory Changes in Irradiated Fresh Pork Packaged in Modified Atmosphere 总被引:3,自引:0,他引:3
The effects of irradiation dose (0, 0.5 and 1.0 kGy), headspace oxygen (0, 10 and 20% O2, balance nitrogen) and storage temperature (5, 15 and 25°C) on the physical, chemical and sensory changes in fresh pork were studied using factorial design experiments. Irradiation in the absence of oxygen extended the sensory shelf life of pork from 9 to 26 days at 5°C and from & lt; 2 to 2 days at 25°C. Oxygen in the package headspace combined with irradiation adversely affected physical, chemical and sensory characteristics of the end product. 相似文献
