The Medium Shapes the Message: McLuhan and Grice Revisited in Race Talk Online

Compared with the wealth of research accumulated on face‐to‐face social interactions, relatively little research has examined race talk within anonymous Web 2.0 mediums. We investigated online threaded comments on YouTube video clips of two race‐related incidents involving New Zealand television presenter Paul Henry. Through thematic content analysis, thematic analysis, and discourse analysis, it was found that characteristics unique to Web 2.0 were associated with the appearance of old‐fashioned racism and high‐levels of obscenity (together with modern racism/symbolic racism). The hyper‐low context of communication led to interpretive ambiguity; conversation sequences failed to follow Gricean maxims for cooperative communication, with most comments attracting no replies and the modal sequence being two turns. There was almost never resolution to a disagreement online: rather there was points‐scoring against opposing opinions and a tangential style of dialogue influenced by the asynchronous and anonymous nature of communication. The YouTube medium shaped but did not determine the message, as obscenity and racist content in the target video from the eliciting public figure influenced the subsequent degree of obscenity and hostility in the responses. A third corpus that examined responses to our own research on race talk presented on a news website (stuff.co.nz) underlined this point by engendering a dramatically different response to the same subject, retaining the tangential style of communication, but with little to no obscenity. A framework to understand race talk as a function of both medium and context effects is proposed. Copyright © 2014 John Wiley & Sons, Ltd.     

On the Possibility of Universal Love for All Humans: A Comparative Study of Confucian and Christian Ethics

On the one hand, Confucianism and Christianity advocate universal love for all humans on the ultimate basis of particular love for parents or for God respectively. On the other hand, they have to sacrifice the former for the latter in cases of conflict since they give top priority merely to the latter. In order to overcome this paradox in theory and realize the ideal of universal love in practice, they should transform their particularistic frameworks into universalistic ones and assign a supreme position to their ideas of universal love for all humans, which imply in a potential way a modern, humanistic principle ‘respect the deserved rights of every human being’.     

Testing an integrated model of the work–family interface in Chinese employees: A longitudinal study

The purpose of this study was to examine an integrated model of the work–family interface (WFI) linking work–family demands (workload and family conflict), resources (supervisory support and family support) and role satisfaction in a Chinese context. The four‐factor structure of WFI comprises direction of influence (work to family vs family to work) and types of effect (work–family conflict vs work–family enrichment). A longitudinal design was used to collect data from 409 Chinese employees at three time points, separating measures of antecedents (T1), WFI (T2) and outcomes (T3) in time. The results based on structural equation modelling (SEM) reveal that: (1) the direction and types of effect were two underlying dimensions of the WFI, supporting the four‐factor structure; (2) demands were more strongly related to conflict, while resources were more strongly related to enrichment; (3) work–family conflict and enrichment were related to role satisfaction, regardless of the direction of influence.     

Tracing children's vocabulary development from preschool through the school‐age years: an 8‐year longitudinal study

In this 8‐year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty‐four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept‐slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high‐high (with a large initial vocabulary size and a fast growth rate), low‐high (with a small initial vocabulary size and a fast growth rate) and low‐low (with a small initial vocabulary size and a slow growth rate) groups. Low‐high and low‐low groups were distinguishable mostly through phonological skills, morphological skills and other reading‐related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language‐related and reading‐related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development.     

Perception of parents as demonstrating the inherent merit of their values: Relations with self‐congruence and subjective well‐being

This study focuses on the parenting practice of inherent value demonstration (IVD), involving parents' tendency to express their values in behaviours and appear satisfied and vital while doing so. Data from Chinese college students (n = 89) confirmed the hypothesis that offspring's perception of their parents as engaged in IVD predicts offspring's subjective well‐being (SWB) through sense of self‐congruence. Importantly, these relations emerged also when controlling for fundamental autonomy‐supportive (FAS) parenting practices such as taking children's perspective, minimising control and allowing choice. These findings are consistent with the view that parents concerned with their children's sense of autonomy may do well to engage in IVD in addition to more fundamental autonomy‐supportive practices. Future research may examine the role of IVD in promoting authentic values that serve as an internal compass that guides children to act in ways that feel self‐congruent.     

Electrolytic lesions of the medial prefrontal cortex do not interfere with long-term memory of extinction of conditioned fear

Lesion studies indicate that rats without the medial prefrontal cortex (mPFC) have difficulty recalling fear extinction acquired the previous day. Several electrophysiological studies have also supported this observation by demonstrating that extinction-related increases in neuronal activity in the mPFC participate in expression of fear extinction. However, a more recent study has shown that fear extinction can be recalled, in certain circumstances, without mPFC potentiation, suggesting contribution of other circuits. Here, we examined this possibility in rats that were subjected to auditory fear conditioning, extinction training, and extinction retention test 7 d later. Electrolytic lesions were made in the mPFC, the motor cortex (MO), the dorsal septum (SEP), or the mediodorsal thalamus (MD), because of their potential participation in conditioned fear inhibition; combined lesions including the mPFC with the MO, SEP, or MD were also made. The lesions were made either 1 wk before conditioning or 1 d after extinction training. All rats normally extinguished their conditioned freezing behavior during extinction training and did not display any return of this behavior during the retention test. These data reveal that the mPFC is not required for the acquisition, the expression, or the retrieval of extinction memories but do not exclude the possibility that the mPFC normally participates in these processes.
