Emotion dialogues between mothers and children at 4.5 and 7.5 years: relations with children's attachment at 1 year 总被引:1,自引:0,他引:1
It was examined whether secure infant-mother attachment contributes to emotionally congruent and organized mother-child dialogues about emotions in later years. The attachment of 99 children was assessed using the Strange Situation at the age of 1 year and their emotion dialogues with their mothers were assessed at the ages of 4.5 and 7.5 years. Dialogues were about past emotional events and separation of a child from parents, and were classified into an emotionally matched group or 1 of 3 non-emotionally matched groups. Security in infancy was associated with emotionally matched dialogues at the age of 4.5; there was moderate stability in dialogues between 4.5 and 7.5 years; and infant attachment predicted dialogues at 7.5 beyond the prediction offered by age 4.5 dialogues. 相似文献

This paper describes implementation (fidelity, perceived acceptability) and tier 1 and Tier 2 outcomes of school‐wide positive behavior interventions and supports approach including mental health supports at Tier 2 in two K‐8 urban schools. Interventions for Tier 2 consisted of three manualized group cognitive behavioral therapy (GCBT) protocols for externalizing behavior problems, depression, and anxiety. Tier 1 and Tier 2 interventions were implemented with fidelity but program feasibility for Tier 2 was in question because school personnel needed a great deal of external support to implement the interventions. Tier 1 interventions were associated with a decrease in office discipline referrals. Students participating in GCBT showed a significant decrease in mental health diagnostic severity at posttreatment. A discussion of perceived and actual implementation barriers and how they were addressed is provided. Implications for practice in low‐income urban schools are discussed. 相似文献

Recently, historians have focused on Warren S. McCulloch's role in the cybernetics movement during the 1940s and 1950s, and his contributions to the development of computer science and communication theory. What has received less attention is McCulloch's early work in neurophysiology, and its relationship to his philosophical quest for an 'experimental epistemology' - a physiological theory of knowledge. McCulloch's early laboratory work during the 1930s addressed the problem of cerebral localization: localizing aspects of behaviour in the cerebral cortex of the brain. Most of this research was done with the Dutch neurophysiologist J.G. Dusser de Barenne at Yale University. The connection between McCulloch's philosophical interests and his experimental work can be expressed as a search for a physiological a priori, an integrated mechanism of sensation. 相似文献

A case of anti-trilodothyronine autoantibodies is presented in this report. The thyroid hormone profile of a hypertensive
patient, with multinodular goiter and history of exogenous thyroid hormone therapy, was found to be highly ambiguous. The
total as well as free T3 levels were consistently high (out of range) whereas the T4 (total and free) values were always within
normal limits. The thyrotropin was found to be partially suppressed. Very low T3-Uptake indicated some kind of interference
in the immunoassays. We incubated the sera with the radio-iodine labelled T3 and observed that the patient's serum bound about
ten times more radioactivity than a control run in parallel. On further resolving the serum proteins on cellulose acetate
electrophoresis, the radioactivity was detected in the γ-globulin band. Therefore it was established that the patient's serum
carried the antibodies reactive with T3 which were interfering in the immunoassays. Elevated anti-thyroid microsomal antibodies
were also present in the patient's serum. The anti-T3 antibodies were highly specific for T3 and did not show any cross reactivity
with the T4 or its analogues used in the estimation of free T4. 相似文献

Research evaluating models of scientific productivity require coherent metrics that quantify various key relations among papers as revealed by patterns of citation. This paper focuses on the various conceptual problems inherent in measuring the degree to which papers tend to cite other papers written by authors of the same nationality. We suggest that measures can be given a degree of assurance of coherence by being based on mathematical models describing the citation process. A number of such models are developed. 相似文献

Optimal loan periods 总被引:1,自引:0,他引:1
Abraham Bookstein 《Information processing & management》1975,11(8-12)
The influence of a library's loan period on user satisfaction is a topic of considerable current interest. In this paper a model is created that is useful for studying this interaction. A policy, possibly appropriate for a reserve book room, is assumed, in which no queues form. Users not able to take out a book either give up or return. Also, the model includes the effect of a patron not being able to use a book for a sufficient length of time. This model yields equations for the value of the loan period that minimizes the number of transactions at the circulation desk consistent with a constant level of real demand. An iterative solution procedure is described and its convergence proven. Other objective functions, and in particular, the probability of a user successfully using a book, are considered.The objective of the paper is not to detail an operating procedure for circulation systems, but to continue the discussion initiated by Philip Morse about how such systems can be modelled. Morse introduces a queuing model for circulating books, but neglects to consider the impact of queue formation on the arrival rate to the system. The intention of this paper is to emphasize the necessity of introducing such considerations and to indicate how such complications can be analytically treated. The specific system modelled is a simplified one, similar to the one discussed by Bruce in a recent article published in L.Q. This model, or variants adapted to local conditions should be useful in assisting decision-making regarding circulation, but it is the modelling process rather than the management aspect that is addressed by this paper. 相似文献
