China's one-per-hundred population survey, conducted in mid-1987, provides the first nation-level data with which to study recent fertility change in China. Using a recently developed extension of the ‘own-children’ method of fertility estimation, period parity progression ratios are computed from the survey data. Comparison with similar statistics computed from the 1982 one-per-thousand fertility survey provides a rigorous check on the quality of the results. The level of fertility so measured rose by 13 per cent between 1985 and 1987, compared with an increase of eight per cent in conventional total fertility ratios. Nearly 90 per cent of the increase was due to rising levels of progression from first to second birth. There can be little doubt that this, in turn, was due to a relaxation in the one-child family policy. Overall levels of progression to births of higher orders have been declining since 1982, but the evidence suggests that this is so only because of stringent government efforts to control births of third and higher orders.  相似文献

ABSTRACT

Using the Gezi Park protests as a case study this article considers the performative component of protest movements including how and why protestors actively produce protest activity ‘on the ground’ and how this is expressed through visual images. It looks beyond iconic images which appear as emblematic of the protest and instead shifts our focus to consider the more ‘everyday’ or mundane activities which occur during a protest occupation, and explores how social media allows these images to have expressive and communicative dimensions. In this respect, protests can be performed through humdrum activities and this signifies a political voice which is communicated visually. The research is based on visual analysis of Twitter data and reveals methodological innovation in understanding how protestors communicate.  相似文献

A computer simulation is used to study collective judgements that an expert panel reaches on the basis of qualitative probability judgements contributed by individual members. The simulated panel displays a strong and robust crowd wisdom effect. The panel’s performance is better when members contribute precise probability estimates instead of qualitative judgements, but not by much. Surprisingly, it does not always hurt for panel members to interpret the probability expressions differently. Indeed, coordinating their understandings can be much worse.  相似文献

The relations between prosocial risk taking (taking a risk to benefit another person; PSRT) and interpersonal regret (regret that one's choices have caused a poor outcome for another person) were examined in 192 children aged 7–9. PSRT was measured by children's choices within a gambling task in which one choice guaranteed participants a good prize whereas the other involved risking this prize to help a peer also win a good prize. Interpersonal regret was assessed within the same task by examining children's change in emotion when they learned they would have won a better prize for a peer had they chosen differently. Performance on this task was also examined in relation to sympathy and resource sharing. Findings indicated that the operationalizations of PSRT and interpersonal regret were meaningful. Children who took a prosocial risk were more generous in a resource sharing task. In some circumstances, children who took a prosocial risk were also more likely to experience interpersonal regret than those who did not take a prosocial risk, indicating that experiencing interpersonal regret may be related to individual differences in prosociality. However, experiencing interpersonal regret did not have a direct effect on subsequent prosocial behavior, when measured by resource sharing. We consider findings in relation to a possible distinction between outcome and process regret and the generalizability of the behavioral consequences of regret.  相似文献

The adult literacy rate, a commonly used indicator of male and female literacy, gives an unnecessarily incomplete picture of progress toward gender equality and universal literacy. Age‐specific literacy rates provide evidence of changing male and female literacy for up to seven decades prior to a census. When available for two or more successive censuses, they provide a powerful test of data quality. In Malawi, the gender gap in literacy disappeared in 2000, and near‐universal literacy is likely to be achieved during the present decade. Much the same is true of El Salvador. The gender gap in Vietnam had dwindled to insignificance by the early 1980s. In Morocco, the gap narrowed steadily between 1940 and 2000 and may disappear by 2015. Despite these successes, adult literacy rates may take another half century or more to reach similar levels. This lag is a consequence of the intrinsic population dynamics of literacy.  相似文献
