We investigated the correspondence between perceived meanings of smiles and their morphological and dynamic characteristics.
Morphological characteristics included co-activation of Orbicularis oculi (AU 6), smile controls, mouth opening, amplitude, and asymmetry of amplitude. Dynamic characteristics included duration,
onset and offset velocity, asymmetry of velocity, and head movements. Smile characteristics were measured using the Facial
Action Coding System (Ekman et al. 2002) and Automated Facial Image Analysis (Cohn and Kanade 2007). Observers judged 122 smiles as amused, embarrassed, nervous, polite, or other. Fifty-three smiles met criteria for classification as perceived amused, embarrassed/nervous, or polite. In comparison with
perceived polite, perceived amused more often included AU 6, open mouth, smile controls, larger amplitude, larger maximum
onset and offset velocity, and longer duration. In comparison with perceived embarrassed/nervous, perceived amused more often
included AU 6, lower maximum offset velocity, and smaller forward head pitch. In comparison with perceived polite, perceived
embarrassed/nervous more often included mouth opening and smile controls, larger amplitude, and greater forward head pitch.
Occurrence of the AU 6 in perceived embarrassed/nervous and polite smiles questions the assumption that AU 6 with a smile
is sufficient to communicate felt enjoyment. By comparing three perceptually distinct types of smiles, we found that perceived
smile meanings were related to specific variation in smile morphological and dynamic characteristics.

In this article, we undertake an event-history analysis of fertility in Ghana. We exploit detailed life history calendar data
to conduct a more refined and definitive analysis of the relationship among personal traits, urban residence, and fertility.
Although urbanization is generally associated with lower fertility in developing countries, inferences in most studies have
been hampered by a lack of information about the timing of residence in relationship to childbearing. We find that the effect
of urbanization itself is strong, evident, and complex, and persists after we control for the effects of age, cohort, union
status, and education. Our discrete-time event-history analysis shows that urban women exhibit fertility rates that are, on
average, 11% lower than those of rural women, but the effects vary by parity. Differences in urban population traits would
augment the effects of urban adaptation itself. Extensions of the analysis point to the operation of a selection effect in
rural-to-urban mobility but provide limited evidence for disruption effects. The possibility of further selection of urbanward
migrants on unmeasured traits remains. The analysis also demonstrates the utility of an annual life history calendar for collecting
such data in the field. 相似文献

In the past 15–20 years, the rural areas of England have been used by a wide diversity of groups as the stage for their protest activities. Some have argued that this is due the rise of a rural social movement; this paper contends that rural areas have become both available and advantageous as the locale of protest through a range of interlocking factors. Firstly, that the rise of the network society has repositioned the societal importance of rural areas. Secondly, that the governance of rural areas has changed, allowing the social stake of rurality to be more widely contested. Thirdly, that opportunities to protest have shifted in favour of rural spaces, in terms of technology and policing. Through a discussion of recent changes in rural England and three case studies, The Land is Ours, Farmers for Action and the Organic Food and Farming Movement, this paper examines these changes and what they mean for the future of rural England. 相似文献

Within the mixed economy of care in the United Kingdom there are debates about the ways in which impact can be evaluated,
in order to shape funding and policy decisions. One of the tensions evident in this debate is whether the evaluation approach
should reflect the perspectives and goals of the voluntary organizations and their members, or whether evaluation should reflect
the wider goals of the whole system of provision. The former runs the risk of being insular and self-congratulatory, while
the latter may be inappropriate and dismissive of achievements. This paper explores this tension by reporting on a study that
used Appreciative Inquiry to evaluate 10 small-scale not-for-profit schemes for older people. The data indicated some unexpected
and long-term impacts that demonstrated the distinctiveness of the sector. Subsequently the findings were mapped on to the
“impact grid” developed by Wilding and Lacey (2003). While this was straightforward at the levels of individuals and interorganizationally,
it was more difficult at the sector/community level, suggesting that more work needs to be done to bring these two perspectives
together. 相似文献

A popular and long‐standing view is that social security is a means for young, unemployed people to “purchase” jobs from older workers. Can social security, by encouraging retirement and hence creating job vacancies for the young, improve the allocation of workers to jobs? Maybe, according to a standard model of labor market search, but public retirement programs currently pay the elderly substantially more than their jobs are worth. An important effect is that retirement reduces the value of other vacant jobs. Our results imply that recent reforms aimed at reducing retirement incentives are likely to improve labor market efficiency. 相似文献

This study examined the relationship among the recovery grip strength, functional outcomes, and work performance following occupational therapy intervention for hand trauma. This study had a sample size of 15 participants whose recovery grip strength was measured using a Jamar dynamometer, whose satisfaction with outcomes was measured by the Michigan Hand Outcomes Questionnaire (MHQ), and whose compliance with the home therapy program was measured by a visual analog scale (VAS). A Pearson r correlation demonstrated a significant relationship between recovery grip strength and two MHQ subset scores: overall hand function (r = 0.59, p = 0.019) and activities of daily living (ADL) performance (r = 0.61, p = 0.016). The participants' self-rating of compliance did not predict or influence either recovery grip strength or MHQ scores. A moderate positive correlation approaching significance (r = 0.51, p = 0.052) was found between grip strength and overall MHQ scores. The researchers concluded that a recovery grip strength measure should be used along with functional measures to appropriately assess overall hand function following hand trauma. 相似文献

A university career development course based on cognitive information‐processing theory was assessed. Students who took the course showed a significant decrease in their negative career thoughts when the Career Thoughts Inventory (J. P. Sampson, G. W. Peterson, J. G. Lenz, R. C. Reardon, & D. E. Saunders, 1996a) was used as a pretest and posttest measure. The greatest decrease in negative thinking was found in students with the highest level of negative thinking at the beginning of the course. The specific components of negative career thinking—decision‐making confusion and commitment anxiety—contributed significantly to the main effect. There were no significant interactions with ethnicity or sex. 相似文献

According to cognitive information processing theory, career thoughts mediate the relationship between career and life stress and the ensuing career decision state. Using a sample of 232 college students and structural equation modeling, this study found that an increase in career and life stress was associated with an increase in negative career thinking and that an increase in such thoughts was associated with a lower level of decidedness and satisfaction with career choice. However, when the variation associated with negative career thoughts was partitioned in the mediated causal model, career and life stress became associated with less career indecision and dissatisfaction with career choice. The results suggest that counselors attend to negative career thoughts when individuals encounter career and life stress. 相似文献

Youth's trust in program leaders is considered a key to the positive impact of youth programs. We sought to understand how trust influences youth's program experiences from their perspective. We interviewed 108 ethnically diverse youth (ages 12–19) participating in 13 arts, leadership, and technology programs. Analysis of these accounts suggested five ways in which youth's trust in leaders amplified program benefits. Trust increased youth's (1) confidence in leaders' guidance in program activities, (2) motivation in the program, (3) use of leaders for mentoring, (4) use of leaders as a model of a well‐functioning relationship, and (5) experience of program cohesiveness. Across benefits, trust allowed youth to draw on leaders' expertise, opened them to new experiences, and helped increase youth's agency. 相似文献
