Relations between maternal sensitivity and physiological reactivity to infant crying were examined using measures of heart rate (HR) and respiratory sinus arrhythmia (RSA) in 49 mothers of second‐born infants. Using the Ainsworth Sensitivity Scale, an independent assessment of maternal sensitivity was made during maternal free play and bathing of their infants. Physiological reactivity was measured while mothers listened to three blocks of infant cry sounds in a standard cry paradigm. Mothers scoring high on sensitivity were compared to less sensitive mothers on both their physiological reactivity to the presented crying sounds and their physiological mean‐level differences. Significant interaction effects were found for both HR and RSA. Highly sensitive mothers showed a larger increase in HR and stronger RSA withdrawal in response to the first block of cry sounds compared to less sensitive mothers. Main effects showed that highly sensitive mothers had lower mean overall HR, and higher mean RSA levels across all three blocks of crying sounds compared to less sensitive mothers. RSA withdrawal and accompanying HR increases are discussed from a polyvagal perspective as indicative of a better capability in responding to infant signals of negative affect. 相似文献

This study argues that in classifying Fayol as a founding father of the Classical Management School, we have to some extent misrepresented this still important management theorist. The received Fayol portrayed in contemporary texts invariably emerges as a caricature of a much more insightful, complex, visionary and rounded management thinker. This study re-examines Fayol's personal and career history, as well as the arguments presented in his original work, General and Industrial Management . It finds that he was a much more complex and multidimensional figure than his conventional stereotype today, and that his management theories embraced a wider spectrum of approaches and concepts than traditionally identified with the classical management school of thought. In marked contrast to his traditional portrayal, this study uncovers traces of ideas and concepts that anticipated aspects of the human relations movement, systems-based contingency theory, the movement towards greater employee involvement in decision-making and elements of knowledge management. 相似文献

Using data on disabilities from the 2000 Census, we found a consistent pattern of living arrangements that leaves children (aged 5 – 15 years) with disabilities living disproportionately with women. Children with disabilities are more likely to live with single parents, and especially their mothers, than are other children. Further, those who do not live with either biological parent are more likely to live in households headed by women than are other children. The results suggest that gendered living arrangements among children with disabilities are a neglected aspect of inequality in caring labor, which is an underpinning of gender inequality in general. 相似文献

The Reed-Frost epidemic model is a simple stochastic process with parameter q that describes the spread of an infectious disease among a closed population. Given data on the final outcome of an epidemic, it is possible to perform Bayesian inference for q using a simple Gibbs sampler algorithm. In this paper it is illustrated that by choosing latent variables appropriately, certain monotonicity properties hold which facilitate the use of a perfect simulation algorithm. The methods are applied to real data. 相似文献

Western U.S. agriculture is an industry that has shaped and been shaped by a peculiar labor policy: seasonal workers were outsiders who looked to agriculture for jobs, not careers. They did not plan to remain farm workers, and the industry and community in which they worked and lived did not see them as long‐term settlers. The immigration and integration policy, in effect, was to recruit new workers willing to accommodate themselves to seasonal employment, and to avoid their integration in agricultural areas. Thus, for most immigrant workers, economic mobility required geographic mobility. However, the major policy issue is not how to enhance the upward mobility of immigrant farm workers and their children; it is how U.S. agriculture should gain access to immigrant farm workers. 相似文献

The A‐not‐B error (Piaget, 1954), which occurs when infants search perseveratively on reversal trials in a delayed‐response task, is one of the most widely studied phenomena in developmental psychology. Nonetheless, the effect of A‐trial experience on the probability and magnitude of this error remains unclear. In this study, 9‐month‐old infants were tested at location A until they searched correctly on 1, 6, or 11 A trials. Results revealed an effect of A trials on the proportion of infants who erred on the first B trial, and on the number of errors prior to a correct search at B (i.e., the error run). These effects were asymptotic, or U‐shaped, consistent with a dual‐process model according to which A‐trial experience increases habit strength but also provides opportunities for reflection on task structure. 相似文献

The concept of control is a prominent component of theories of stress. From a transactional framework, appraisal of control is seen as important in influencing coping behaviour. However, little attention has been paid to the measurement of the appraisal of control in a work-related situation. In this paper it is argued that situational control should not be reduced to a simple assessment of whether or not an individual has control over a given situation. Instead it is believed that it is important to identify the factors that an individual strives to have control of, as well as the perceived degree of control over those factors. A major component of the present study was the use of a measure that viewed control in this way and that examined control as a multifaceted construct (task control, predictability, self-control and general control). This paper reports on an analysis that examines the multifaceted nature of perceived control with other situational appraisals in the process of coping with workplace stress. A total of 134 employees from four public sector organizations in New Zealand took part in this research. Having control over work tasks was for this sample considered to be less important in giving a sense of control than either predictability or self-control. When it came to reporting how much control they actually had, respondents reported higher levels of self-control than other aspects of control. However, in general respondents reported lower levels of actual control than what they perceived it was important for them to have. This research emphasizes the importance of having a sense of self-control, particularly when it comes to the use of different coping strategies. Overall these findings point to the need to better understand the nature and type of control and its importance if we are to advance our knowledge of work stress. 相似文献

Ogbu’s theories relating to the educational achievement of minorities seem to be at odds with the situation of the largest minority groups in Belgium and the Netherlands. Moroccans form a voluntary minority but, after three generations, their children still lag in terms of school results. Ethnographic research among Moroccans in both countries shows that the community forces that hinder the academic achievement of Moroccan children are in many ways similar to those of minorities that Ogbu calls involuntary. Ogbu’s insights are relevant for the situation of minorities in these countries and deserve more attention, but the initial voluntariness of the migration seems not necessarily to constitute the most crucial influence on community forces. Other factors have to be considered. 相似文献
