To understand social issues and practices such as those related to climate change and technological change that are clearly future-oriented – collectively experienced events that are “not yet” – and co-constructed by different actors, we need nuanced conceptualizations of how people think about, negotiate and co-create futures that allow us to understand not only what people (can) think and do about future-related issues but also how that happens, what for and with which implications. However, so far, one of the key theoretical approaches that has conceptualised how people make meaning in situations of change and uncertainty – the socio-psychological social representations theory (SRT) – has not often engaged with the future or with different forms of temporality. By contrast, the French pragmatic sociology of engagements and critique (PS) has engaged with these notions, conceptualising them in relation to materiality and a plurality of moral orientations – two dimensions often seen as key to how collective futures are made and imagined. To offer a more nuanced and systematic conceptualization of how people represent the future and with what consequences, this paper will present, compare and synthesise SRT and PS, as a first step towards an interdisciplinary research agenda on social change and representations of the future.  相似文献

Generalized-conditioned reinforcers (GCRs) are advocated for by practitioners when possible because of their ability to function as reinforcers across a wide array of motivative operations. In organizational behavior management 2 common GCRs are praise and money. Although many studies have demonstrated their usefulness, no prior study has compared relative preferences for GCRs (specifically money) and other potentially reinforcing items. A total of 24 direct care employees from a group home setting completed assessments for potential reinforcers. All participants in the current study identified items other than money as high-preference items, suggesting that some items may serve as alternatives to money in terms of preference.  相似文献

This paper presents a new measure of association. It is applicable to polytomies of either categorical or numerical type. It has the desirable property of being 0 if and only if the polytomies are independent. Its properties are studied and compared to those of existing measures. An interpretation of it is given. One situation where it is particularly useful is in measuring the ability to predict one polytomy given knowledge of the other. An example is given where the proposed measure is more relevant in describing the degree of association between two polytomies than are any of the existing measures. The corresponding sample quantity is presented and its asymptotic properties are studied. A discussion of its use in inference is given. The test for independence based on this measure is contrasted with the chi-square test.  相似文献

Although white‐collar work is of vast importance to the economy, the operations management (OM) literature has focused largely on traditional blue‐collar work. In an effort to stimulate more OM research into the design, control, and management of white‐collar work systems, this paper provides a systematic review of disparate streams of research relevant to understanding white‐collar work from an operations perspective. Our review classifies research according to its relevance to white‐collar work at individual, team, and organizational levels. By examining the literature in the context of this framework, we identify gaps in our understanding of white‐collar work that suggest promising research directions.  相似文献

We explored the role that exogenous and endogenous competitors for attention play in infants’ abilities to encode and retain information over a 6‐month period. Sixty‐six children visited the laboratory at 15 months, and 32 returned for a second visit at 21 months. Children observed models of conventional‐ relation and enabling‐relation action sequences. Half the children were distracted by a “Mister Monkey” mechanical toy during the conventional‐relation sequence, while the other half was distracted during the enabling‐relation sequence. The Early Childhood Behavior Questionnaire indexed endogenous factors at both ages. Immediate postmodel production of target actions indexed encoding efficiency, and 6‐month production of target actions indexed long‐term recall. The exogenous distracter impacted encoding efficiency (i.e., immediate recall), but not long‐term recall. Endogenous factors (i.e., temperament) were primarily associated with long‐term recall. Of special interest was our finding that endogenous factors, especially surgency, moderated the effect of the exogenous distracter. It appears that when learning conventional‐relation sequences in the presence of exogenous distracters, surgency mobilizes attentional resources toward the learning objective; however, when learning enabling‐relation sequences under the same conditions, surgency either boosts the saliency of the distracters or boosts children’s susceptibility to them.  相似文献

Little is known about mortality among descendants of immigrants in western host countries because many descendants have not yet reached the ages of high mortality. The aim of this paper is to investigate whether the migrant mortality advantage recently observed among immigrants in England and Wales persists, converges to levels of the White England and Wales-born population or reverses among their descendants. Survival analysis is used to study mortality among over 500,000 individuals in a large, longitudinal dataset (Office for National Statistics Longitudinal Study). A recent update to this data provides a longer time series with an older sample of descendants to study. The analysis finds that, as a combined group, the descendants of immigrants have higher mortality than immigrants and White England and Wales-born. After adjusting for socioeconomic characteristics, mortality among descendants attenuates to the mortality level among the White England and Wales-born but remains high relative to immigrants. Analysis by ethnic minority group suggests there are important differences in mortality among descendants, particularly in the persistent high mortality among the descendants of Black Caribbeans. However, the age structure among descendants is still young and the estimates for ethnic minority sub-groups may not be robust. We await the further ageing of descendants to confirm or challenge these interesting sub-group findings by ethnicity.  相似文献

We examined the UK's effectiveness in reducing Child Mortality with 20 other Western countries, in the context of their national health expenditures, and, relative poverty — measured by ‘Income Inequality’ the gap between top and bottom 20 per cent of income. W.H.O. Child (0–14) Mortality Rates (CMR) and GDP Expenditure on Health (% GDPHE) were examined and a cost‐effectiveness ratio calculated, which is the reduced CMR over the period divided by average GDPHE. The highest average % GDPHE was USA at 13.2 per cent; the UK's 7.3 per cent was equal lowest. The widest Income Inequality was USA 8.5 times; the UK at 7.2 was third widest. The highest CMR was the USA 2436 per million (pm), the UK's 1630 pm, although representing a fall of 62 per cent was fourth highest. However, UK cost‐effectiveness ratio (1: 350) was eighth best of 21 countries. Only Income Inequality correlated significantly with CMR. UK CMR fell significantly more than five countries but ten others declined more. If UK deaths had been at the average of the 17 countries with lower CMR, there would have been 1827 fewer deaths. British children's poverty and health expenditure means they and their services are doubly disadvantaged although the NHS relatively achieved more with comparatively less.  相似文献

Whether the video-image of the face was larger than life or about one-fifth life size made no difference in observers' judgments of emotions, attitudes, and personality traits.This research was supported by a grant from NIMH, MH 11976. The preparation of this report was supported by a grant from the Harry F. Guggenheim Foundation, and by a Research Scientist Award, MH 06092 from NIMH.  相似文献
