Color categories: confirmation of the relativity hypothesis

The question of whether language affects our categorization of perceptual continua is of particular interest for the domain of color where constraints on categorization have been proposed both within the visual system and in the visual environment. Recent research (Roberson, Davies, & Davidoff, 2000; Roberson et al., in press) found substantial evidence of cognitive color differences between different language communities, but concerns remained as to how representative might be a tiny, extremely remote community. The present study replicates and extends previous findings using additional paradigms among a larger community in a different visual environment. Adult semi-nomadic tribesmen in Southern Africa carried out similarity judgments, short-term memory and long-term learning tasks. They showed different cognitive organization of color to both English and another language with the five color terms. Moreover, Categorical Perception effects were found to differ even between languages with broadly similar color categories. The results provide further evidence of the tight relationship between language and cognition.

A comparison of international HRM practices by Indian and European MNEs:evidence from Africa

By comparing the HRM practices in Indian and European MNE subsidiaries located in four of the Southern African Development Community countries, this paper tests the relevance of the country-of-origin effect and analyses the strength of institutional and firm-level influences. Examining data from 865 MNE subsidiaries obtained from the World Bank enterprise survey data, the paper finds that Indian MNEs have higher labour costs in relation to total sales than their European counterparts, that Indian MNEs make more use of temporary labour than their European counterparts, that Indian MNEs invest in less training than their European counterparts. No support is found for the hypothesis that Indian MNEs have a lower ratio of skilled workers in comparison to European-owned subsidiaries. The study shows that country-of-origin effects are weakened if they are not consistent with host country ideology and that as economies evolve so too do their expectations of HR policy and practices. © 2014 © 2014 Taylor & Francis.
