This study tested a model of the association between maternal and child anxiety that views mother and child attachment beliefs and children's perceptions of maternal control as mediators of the association. The study was conducted with mothers and their children aged 6 to 17 (N = 88). Maternal anxiety was significantly associated with child anxiety and maternal anxious attachment beliefs, whereas child anxiety was associated with maternal anxious attachment beliefs, child insecure attachment beliefs, and children's perceptions of maternal control. Maternal anxious attachment beliefs mediated the association between maternal and child anxiety; however, child attachment beliefs and children's perceptions of maternal control did not. The influence of age and gender is also addressed. The findings are discussed in terms of elucidating the role of attachment beliefs and children's perceptions of maternal control on the association between maternal and child anxiety.  相似文献

The present study was designed to assess the contribution of general features of gross body movements to the attribution of emotions. Eighty-five adult subjects were shown ninety-six videotaped body movements, performed by three actors. Each movement was determined by seven general dimensions: trunk movement, arm movement, vertical direction, sagittal direction, force, velocity and directness. Using rating scales, the subjects judged the compatibility of each movement with each of twelve emotion categories. The results showed which movement features predicted particular ratings. Emotion categories differed as to the amount, type, and weights of predicting movement features. Three factors were extracted from the original ratings and interpreted as Rejection-Acceptance, Withdrawal-Approach, and Preparation-Defeatedness.I wish to thank Jacques van Meel for his stimulating contribution to this study, and the reviewers for their comments on earlier drafts of the final report.  相似文献

The ongoing debate over the flaws in the nation's welfare system centers primarily on two highly charged social ills: teen-age pregnancy and long-term dependence on public assistance. For the poorest and fastest growing segment of the welfare population—homeless mothers—these problems are both severe and inextricably linked. At an alarmingly young age, these women are becoming trapped in a chaotic cycle that offers little structure and few alternatives.  相似文献

This research exploits a large matched employer–employee data set for an Italian region, the Veneto, that is presented here for the first time, in order to analyse job and worker flows. In a first part, the paper computes worker turnover, job turnover, and excess worker reallocation over a time span of 14 years. The results are discussed, and comparisons are made between the quantitative features of the labour market in the Veneto region and those of other labour markets. In a second part, turnover and excess worker reallocation are related to search costs, and new empirical evidence is presented that helps in understanding the connections between search activity, unemployment, and the economic cycle.  相似文献

The audit fees available since 2005 as a consequence of the Bilanzrechtsreformgesetz (commercial code reform act) show an extremely high supplier concentration on the German audit market of publicly listed companies. This justifies the assumption of audit fees above perfect market equilibrium prices. However, the complete collection and multivariate regression analysis of all relevant audit fee and client data document a 24 % decrease in audit fees in 2005 and an average 15 % decrease in the two subsequent years due to auditor changes. This can be interpreted as an indicator for price competition. In addition, the audit fee data shows that the audit fee decreases are only partially compensated by subsequent increases. As a consequence, there is no evidence for lowballing at present. Further time series are necessary to show if the current trend is sustainable.  相似文献

Several important economic time series are recorded on a particular day every week. Seasonal adjustment of such series is difficult because the number of weeks varies between 52 and 53 and the position of the recording day changes from year to year. In addition certain festivals, most notably Easter, take place at different times according to the year. This article presents a solution to problems of this kind by setting up a structural time series model that allows the seasonal pattern to evolve over time and enables trend extraction and seasonal adjustment to be carried out by means of state-space filtering and smoothing algorithms. The method is illustrated with a Bank of England series on the money supply.  相似文献

The present study aims to develop an index composed of different spatial variables to measure the urban sprawl levels of a municipality located in Southern Spain. According to the findings, urban sprawl can be measured not only on the metropolitan level but also on a more detailed and precise level, such as sub-municipal. A group of experts chosen for their suitability in measuring urban sprawl select six spatial variables (population density, net residential density, coverage ratio, land use types, percentage of residential land use, and average year of construction). These variables are aggregated using Choquet integral, a technique that combines interactions between those variables providing greater coherence to the complexity that is inherent in the creation of composite sprawl indexes. This methodology has been demonstrated to be valid and appropriate in evaluating urban expansion at sub-municipal level, but can also be applied to other scales once it is clearly a phenomenon in which interaction between criteria exists. The resulting composite index allows the assignment of different levels of sprawl to the urban areas consistent with their morphology and landscape.  相似文献
