In five subjects, head movement during conversation was monitored by polarised light goniometry, and recorded alongside speech and a signal proportional to peak amplitude of sound waves (peak loudness). Kinematic properties of listeners' head movements, such as amplitude, frequency and cyclicity, differentiated various conversational functions. That is, they were function-specific: symmetrical, cyclic movements were employed to signal yes, no or equivalents; linear, wide movements anticipated claims for speaking; narrow linear movements occurred in phase with stressed syllables in the other's speech (ynchrony movements); and wide, linear movements occurred during pauses in the other's speech. That, it is argued, bears upon the relation between thesignalling of communicative intentions and the synchronisation of interactional rhythm. Thus, the former appears to determine the timing and tempo of responses such as yes and no, while the latter determines the regulation of synchrony movements. The manner in which these factors interact in other conversational functions and their theoretical implications are discussed. 相似文献

Evaluative studies of senior center utilization traditionally rely on numerical increase of participation as a principle criterion for determining success. This study compares the participation patterns of 54 high- and low-frequency users of an urban senior center for the purpose of identifying actors which influence usage. The chi-square and point biserial correlation coefficient were statistics utilized for the purpose of identifying relationships between 16 variables. The subjects were similar with regard to health, mobility, access to the center, and disengagement potential. Significant relationships were identified between usage and: life space, club affiliation, alternative activities, friends outside the center, living arrangements, and duration of membership. The data suggest that usage appears to be influenced by social losses and gains, which provides a novel perspective of participation and attrition. Therefore, evaluative studies of senior center utilization might consider not only numerical criteria of usage, but the process by which individuals initiate participation and subsequently decrease their involvement. 相似文献

Return migration is key to community recovery from many disasters. Japanese governments have conducted radiation decontamination efforts in the Exclusion Zone designated after the 2011 Fukushima nuclear disaster in order to encourage this outcome. Little is known, however, about the factors that influence post-disaster migrants to return, and, if people are relatively unresponsive to decontamination, then the costs of promoting recovery may exceed the benefits. We exploit a unique survey of Fukushima evacuees to determine the factors that influence their decision to return after a disaster. Location-specific capital characteristics, such as housing tenure and the extent of property damage, are estimated to be strong factors. The radiation dose rate of the home location is found to be a statistically significant factor for intent to return, but its effect is small. We also found that households with various other characteristics were noncommittal about the return option and likely to defer their decisions, which implies that “return” and “not-return” are asymmetric. Our simulation analysis found that the number of returnees encouraged by this decontamination was 12,882, less than 8% of the total evacuees, while the decontamination cost per returnee was 3.36 million USD. This result implies that the government could have improved the well-being of evacuees at a lower cost by policies other than decontamination. 相似文献

The present research examines social influences on self‐reported frequency of drunkenness in a longitudinal sample of 1,439 adolescents (46% female, 90% White, mean age = 14 at baseline) with social network measures from friends, romantic partners, and romantic partners’ friends. We build on past research by addressing multiple mechanisms of social influence—peers’ frequency of drunkenness, alcohol‐related attitudes, and unstructured socializing—across relationship types. Adolescents’ drunkenness frequency increased when their friends’ and partners’ friends’ drunkenness frequency increased and when their romantic partners’ positive alcohol‐related attitudes increased. Furthermore, the association between unstructured socializing and frequency of drunkenness was stronger for older than younger adolescents. Results advance understanding of the social transmission of alcohol use in adolescence and inform intervention efforts. 相似文献

The proliferation of artificial lighting at night is one of the key anthropogenic changes associated with urbanised areas as well as some non-urban areas. Disruption to natural light/dark regimes can have considerable effects on the timing of different behaviours of birds, particularly during the breeding season. However, the effect of artificial lights on the timing of behaviours during winter has received relatively little attention, despite the fact that time partitioning of foraging can have implications for avian winter survival. In this study, we assess at a landscape scale during winter, whether birds arrive at feeding stations earlier in areas with increased levels of artificial lighting using data from a citizen science project. Arrival times of the ten most commonly recorded species were associated with a combination of the density of artificial lights, temperature, rainfall and urban land cover. We found no evidence that birds advance the onset of foraging in gardens with more artificial lights nearby; contrary to our prediction, birds generally arrived later into these areas. This is possibly a response to differences in food availability or predation risk in areas with more artificial lights. We conclude that artificial light at night may not be as important for driving the timing of foraging behaviour in winter as previously thought, but it remains to be seen whether this represents a missed opportunity to extend the foraging period or an adaptive response. 相似文献

Early cities depended on local, solar-based energy resources for their metabolism. Over time, cities have become increasingly dependent on fossil fuels, both directly and indirectly, as they facilitate exploitation of solar resources from much farther away. Alternatives to fossil fuels, typically generated locally, often provide lower surplus energy to society. As cities consider the transition back to solar-based energy resources, it becomes necessary to understand the capability of the solar-based economy to provide e.g. energy (including food) from nearby lands. To do so, we compared the energy metabolism (respiration) of a typical rust-belt city, Syracuse, NY, with the net primary production in the surrounding county (production) over its development (1840–2005). We calculated the ratio of respiration to production (R:P) and examined how this ratio changed during the periods of industrialization, shifts in major fuel types, and deindustrialization. We found that from 1840 to 1950 respiration became increasingly centralized in the urban core; since then it has become more diffused. Urban respiration exceeded production in the county by 9:1 in 1930, and it remains just under 2:1 today. Respiration reached an absolute (67 PJ) and a per capita (339 GJ) maximum in 1970, then fell by 40 % and 20 % respectively, due to deindustrialization and population losses. Conversely, production increased 480 % from its lows in 1930 because of reforestation and improved agricultural yields. What this means is that to achieve a higher P:R ratio requires either increased production of food and fuels in areas surrounding the city, or decreased per capita energy consumption. 相似文献

The last decade has witnessed a proliferation of lesbian representations in European and North American popular culture, particularly within television drama and broader celebrity culture. The abundance of “positive” and “ordinary” representations of lesbians is widely celebrated as signifying progress in queer struggles for social equality. Yet, as this article details, the terms of the visibility extended to lesbians within popular culture often affirm ideals of hetero-patriarchal, white femininity. Focusing on the visual and narrative registers within which lesbian romances are mediated within television drama, this article examines the emergence of what we describe as “the lesbian normal.” Tracking the ways in which the lesbian normal is anchored in a longer history of “the normal gay,” it argues that the lesbian normal is indicative of the emergence of a broader post-feminist and post-queer popular culture, in which feminist and queer struggles are imagined as completed and belonging to the past. Post-queer popular culture is depoliticising in its effects, diminishing the critical potential of feminist and queer politics, and silencing the actually existing conditions of inequality, prejudice, and stigma that continue to shape lesbian lives. 相似文献

Social work has historically privileged one-to-one supervision in field education. However, in recent decades, the relentless pressure on organisations to innovate for efficiency gain has created an impetus to explore alternative placement formats. This article reports on how students and supervisors experienced their placement relationships in the context of one such alternative—a team-based rotation placement model where students routinely engaged in group and peer supervision as well as one-to-one supervision with various supervisors. A total of 128 Masters of Social Work students and 92 student supervisors participated in rotation placements across five hospitals over a three-year period; 2011–2013. The study adopted a mixed methods approach using online surveys and post-placement interviews each year. The findings suggest that, although both supervisors and students viewed the one-to-one supervisory relationship as pivotal, they experienced this relationship differently. Supervisors were more likely to highlight the interpersonal connection within the supervisory relationship as the primary vehicle for practice learning. Students were more likely to view their supervisory relationships as the conduit to the practice experiences that aligned with their placement goals. Ultimately, the study highlights the centrality of role and positioning when exploring perceptions and experiences of teaching and learning relationships on placement. 相似文献
