This article presents a cross‐variety investigation of quotatives be like and go in apparent and real time. Distributional and attitudinal evidence points to a change in progress as the underlying process for the distribution of be like. However, there is also evidence of life‐span change (Sankoff to appear). The patterning of go across age is much less clear‐cut. It could be interpreted as age grading or as a change in progress. This paper discusses seemingly contradictory findings from U.S. and British English. It will be suggested that the distribution of go is due to unstable behaviour at both the individual and the community level. Furthermore, there is evidence that go has a latent presence in the linguistic repertoire and was picked up again after its frequency dipped due to the introduction of be like. This finding ties in with other reported cases of recycling of variables ( Dubois and Horvath 1999 ).  相似文献

This paper uses a data base covering the universe of French firms for the period 1990–2007 to provide a forensic account of the role of individual firms in generating aggregate fluctuations. We set up a simple multisector model of heterogeneous firms selling to multiple markets to motivate a theoretically founded decomposition of firms' annual sales growth rate into different components. We find that the firm‐specific component contributes substantially to aggregate sales volatility, mattering about as much as the components capturing shocks that are common across firms within a sector or country. We then decompose the firm‐specific component to provide evidence on two mechanisms that generate aggregate fluctuations from microeconomic shocks highlighted in the recent literature: (i) when the firm size distribution is fat‐tailed, idiosyncratic shocks to large firms directly contribute to aggregate fluctuations, and (ii) aggregate fluctuations can arise from idiosyncratic shocks due to input–output linkages across the economy. Firm linkages are approximately three times as important as the direct effect of firm shocks in driving aggregate fluctuations.  相似文献

Assessment of efficacy in important subgroups – such as those defined by sex, age, race and region – in confirmatory trials is typically performed using separate analysis of the specific subgroup. This ignores relevant information from the complementary subgroup. Bayesian dynamic borrowing uses an informative prior based on analysis of the complementary subgroup and a weak prior distribution centred on a mean of zero to construct a robust mixture prior. This combination of priors allows for dynamic borrowing of prior information; the analysis learns how much of the complementary subgroup prior information to borrow based on the consistency between the subgroup of interest and the complementary subgroup. A tipping point analysis can be carried out to identify how much prior weight needs to be placed on the complementary subgroup component of the robust mixture prior to establish efficacy in the subgroup of interest. An attractive feature of the tipping point analysis is that it enables the evidence from the source subgroup, the evidence from the target subgroup, and the combined evidence to be displayed alongside each other. This method is illustrated with an example trial in severe asthma where efficacy in the adolescent subgroup was assessed using a mixture prior combining an informative prior from the adult data in the same trial with a non-informative prior.  相似文献

Switzerland’s social policies in the field of disability have been significantly reshaped over the last two decades by reducing the number of allowances awarded and by increasing the recourse to vocational rehabilitation measures. What stances do individuals who experience the implementation of these policies adopt? What kind of tests are they subjected to? How can we explain the posture they adopt – be it ‘compliant’, ‘pacified’ or ‘rebellious’ – when facing the (re)assignations of their identity and professional status? Drawing on interviews conducted with individuals who have recently been involved in programmes set up by Swiss disability insurance, we highlight their uncertainties and concerns relating to their place in society, as well as their reactions to disability insurance’s interventions.  相似文献

ABSTRACT

We estimate the relationships between early initiation of marijuana use (i.e., during middle school or high school), educational attainment and performance, and earnings as a young adult. Grounded in a developmental stages theoretical framework, results indicate that early initiation of marijuana use is negatively related to both educational outcomes and earnings, but the estimated relationships for earnings are diminished in models that control for education and other socioeconomic characteristics. These findings are consistent with the hypothesis that early marijuana use indirectly affects young adult earnings through its negative effects on educational outcomes. Our results also indicate that early marijuana initiators who grow up in economically disadvantaged families may have worse educational outcomes than their counterparts who do not grow up with economic disadvantages. Reduced education and earnings among young adults could increase the likelihood of the individual and their family suffering economic hardships later in life.  相似文献

Apparent time analysis has revealed that the Tyneside face vowel is the site of two intersecting trends: levelling towards the supra‐northern monophthong as well as the gradual incursion of the southern standard closing diphthong. This article investigates the participation of individual speakers across their life‐span in these ongoing changes in the face vowel. We report on a small‐scale panel sample of six speakers who were recorded in 1971 and again, 42 years later, in 2013. The analysis probes the stability of individual speakers’ grammars, relying on longitudinal ethnographic analysis in the community as well as insights gleaned from sociolinguistic interviews about the speakers’ socio‐demographic trajectory and their presentations of self. The article contributes to the growing body of panel research that aims to determine the scope and the limits of linguistic malleability across speakers’ life histories.  相似文献

Gambling behavior is partly the result of varied motivations leading individuals to participate in gambling activities. Specific motivational profiles are found in gamblers, and gambling motives are closely linked to the development of cognitive distortions. This cross-sectional study aimed to predict cognitive distortions from gambling motives in poker players. The population was recruited in online gambling forums. Participants reported gambling at least once a week. Data included sociodemographic characteristics, the South Oaks Gambling Screen, the Gambling Motives Questionnaire-Financial and the Gambling-Related Cognition Scale. This study was conducted on 259 male poker gamblers (aged 18–69 years, 14.3% probable pathological gamblers). Univariate analyses showed that cognitive distortions were independently predicted by overall gambling motives (34.8%) and problem gambling (22.4%) (p < .05). The multivariate model, including these two variables, explained 39.7% of cognitive distortions (p < .05). The results associated with the literature data highlight that cognitive distortions are a good discriminating factor of gambling problems, showing a close inter-relationship between gambling motives, cognitive distortions and the severity of gambling. These data are consistent with the following theoretical process model: gambling motives lead individuals to practice and repeat the gambling experience, which may lead them to develop cognitive distortions, which in turn favor problem gambling. This study opens up new research perspectives to understand better the mechanisms underlying gambling practice and has clinical implications in terms of prevention and treatment. For example, a coupled motivational and cognitive intervention focused on gambling motives/cognitive distortions could be beneficial for individuals with gambling problems.  相似文献

Recent data suggest the importance of identifying subtypes of pathological gamblers. This research studies sensation seeking, alexithymia and depression among a general population of French gamblers who play different types of game. Those games include games available in cafés (two cafés located in Paris suburb) like lottery, scratch-cards, etc., horse betting at the racetrack (five racetracks closest to Paris), slot machines and traditional games (roulette and card games) at the casino of Enghien-les-Bains (casino nearest to Paris). Sensation seeking was measured with the SSS form V, alexithymia with the TAS-20, and depression with the BDI-13. Pathological racetrack gamblers (42 males; mean age 29.1 years), who play active games involving skills, have the highest sensation seeking scores and are the most prone to alexithymia. Pathological gamblers playing the slot machines (12 males; 15 females; mean age 35.7 years) and games available in cafés (57 males; mean age 32.6 years), thus playing passive games that involve chance only, have low sensation seeking scores. Slot machines gamblers display alexithymia and have the highest depression scores. Pathological gamblers playing traditional games (15 males; mean age 37.8 years), games that involve strategy, do not perform well on any of these scales. These findings are consistent with the idea that clinically distinct subgroups of pathological gamblers can be identified. People displaying typical features could be attracted by specific games.  相似文献
