A NOTE ON EVANESCENT PROCESSES 总被引:1,自引:0,他引:1
This note examines the connection between μ-invariant measures for the transition function of a continuous-time Markov chain and those of its q-matrix, Q. The major result establishes a necessary and aufficient condition for a convergent μ-invariant measure for Q to be μ-inhant for the minimal transition function, P, under the assumption that P is honest. This corrects Theorem 6 of Vere-Jones (1969) and the first part of Corollary 1 of Pollett (1986), both of which assert that the above conclusion holds in the absence of this condition. The error was pointed out by E.A. van Doom (1991) and the counterexample which be presented provides the basis for the present arguments. In determining where the error occurred in the original proof, we are able to identify a simple sufficient condition for μ-invariance. 相似文献

A role-reversal in the mother-daughter relationship 总被引:1,自引:1,他引:0
Roberta Kabat Ph.D. 《Clinical Social Work Journal》1996,24(3):255-269
Psychoanalytic theorists have noted a particular dynamic in the mother-infant relationship in which the emotional needs of the mother predominate. When this situation occurs, the emotional needs of the infant may go unmet, resulting in impaired self-development. Through an integration of the ideas of mainstream psychoanalytic theorists and feminist psychoanalytic thinkers, this paper proposes the idea that, because of the intensity of the mother-daughter relationship, this dynamic may be more prevalent between mothers and daughters than between mothers and sons. A mother-daughter relationship is described in which the mother comes to depend on her daughter for emotional attunement and response, and the mother's selfobject needs predominate. As a consequence, the daughter is unable to develop a cohesive sense of self and experiences difficulty in achieving separation. Two clinical reports are presented to illustrate the way in which this mother-daughter dynamic manifests itself in the patient's life and in the therapeutic relationship. A negative transference dynamic is described resulting from these patient's fear of duplicating their relationship with their mothers in the therapeutic relationship by having to meet the selfobject needs of the therapist. 相似文献

The 'negotiated night': an embodied conceptual framework for the sociological study of sleep 总被引:2,自引:0,他引:2
Robert Meadows 《The Sociological review》2005,53(2):240-254
Sleep is essential for our health and well‐being but it has, historically, been the subject of little sociological study. Yet sleep is not, as common sense would have us believe, ‘asocial inaction’. Like our waking lives, it is a time of interaction. The sociology of sleep presently exists in a state similar to the early stages of development of the sociology of the body, waiting for something like Frank's (1991 ) typology of body action, which served as a heuristic guide through which action and its multifaceted components could be understood. This paper argues that one productive analytical framework is to adapt Watson's (2000 ) ‘male body schema’ for the sociological investigation of sleep. This revolves around four interrelated forms of embodiment: normative (opinions and perceptions about healthy sleep behaviour); pragmatic (‘normal’ as related to social role); experiential (feelings related to sleep); and visceral (the biological body and sleep). The possibilities this model provides for the sociology of sleep is illustrated in the paper through the analysis of a case study of sleep negotiation between a couple. 相似文献

A Continuous Sampling Plan, CSP-CUSUM, is proposed based on the use of Cumulative Sums (CUSUMs) for deciding when to switch between the phases of sampling inspection and 100% inspection. The Geometric CUSUM, also termed the Run-length CUSUM, is chosen for this purpose, and two separate CUSUMs are to be operated, one for each inspection phase. The conventional measures of performance for CSPs such as average outgoing quality, average fraction inspected, and average proportion passed under sampling inspection are evaluated for CSP-CUSUM, and comparisons with some standard CSPs are presented. An additional performance-measure, Average Cycle Length, is proposed. A table is provided to aid the choice of parameters for the operation of CSP-CUSUM. It is recommended that a Geometric CUSUM control chart be maintained in parallel with CSP-CUSUM to detect significant upward shifts in the incoming fraction defective. 相似文献
