In an alloy that is strengthened by long-range-ordered particles, a matrix dislocation generates an antiphase boundary (APB) when it cuts through such a particle. The specific energy n APB of this APB has been measured for two fcc alloys with spherical coherent L12 ordered particles: an Al-7.5at.%Li-alloy and the commercial Ni-base superalloy Nimonic PE16. Peak-aged specimens have been deformed and Orowan loops searched for using transmission electron microscopy. n APB has been derived from the radii of the smallest dislocation loops which have been left behind around particles. Such an approach had been used previously, for example, by Raynor and Silcock and by Nembach et al . Here an improved evaluation method has been applied; it is based on the results of computer simulations of the equilibrium configurations of dislocation loops.  相似文献

Following a hypnotic amnesia suggestion, highly hypnotically suggestible subjects may experience amnesia for events. Is there a failure to retrieve the material concerned from autobiographical (episodic) memory, or is it retrieved but blocked from consciousness? Highly hypnotically suggestible subjects produced free-associates to a list of concrete nouns. They were then given an amnesia suggestion for that episode followed by another free association list, which included 15 critical words that had been previously presented. If episodic retrieval for the first trial had been blocked, the responses on the second trial should still have been at least as fast as for the first trial. With semantic priming, they should be faster. In fact, they were on average half a second slower. This suggests that the material had been retrieved but blocked from consciousness. A goal-oriented information processing framework is outlined to interpret these and related data.  相似文献

Visual cuing studies have been widely used to demonstrate and explore contributions from both object- and location-based attention systems. A common finding has been a response advantage for shifts of attention occurring within an object, relative to shifts of an equal distance between objects. The present study examined this advantage for within-object shifts in terms of engage and disengage operations within the object- and location-based attention systems. The rationale was that shifts of attention between objects require object-based attention to disengage from one object before shifting to another, something that is not required for shifts of attention within an object or away from a location. One- and two-object displays were used to assess object-based contributions related to disengaging and engaging attention within, between, into, and out of objects. The results suggest that the "object advantage" commonly found in visual cuing experiments in which shifts of attention are required is primarily due to disengage operations associated with object-based attention.  相似文献

Recognition of relatives is important for dispersing animals to avoid inbreeding and possibly for developing cooperative, reciprocal relationships between individuals after dispersal. We demonstrate under controlled captive conditions that cotton-top tamarins (Saguinus oedipus) have a long-term memory for long calls of relatives from which they had been separated for periods ranging from 4 to 55 months. Tamarins responded with lower levels of arousal behavior to playbacks of long calls from current mates and from separated relatives compared to calls of unfamiliar, unrelated tamarins. Four tamarins had been out of contact with relatives for more than 4 years and still showed recognition as evidenced by low levels of arousal. Results could not be explained in terms of proximity to former relatives. Long-term memory for vocal signatures of relatives is adaptive and may be much more common than has been demonstrated.  相似文献

Vocational guidance services have been developing in Northern Ireland for about thirty years. Recently the careers service has been transferred from an education to a manpower services base, while the schools have been given greater opportunity, and responsibility, for the provision of careers education. The changes have given considerable impetus to careers teacher training, and to the appointment of schools' careers staffs. The possibility of further development of the partnership between careers officers and careers teachers is examined.  相似文献

Health Psychology has been with us “officially” for about a decade and its development has been rapid and influential. With any new area, particularly one which has developed so quickly, it becomes necessary to take stock in order to assess progress and to identify critical issues. To some extent, this task has been attempted in the United States (see Stone er al.,1987) but there has been no systematic attempt to look at international developments in health psychology. I was therefore particularly pleased when Mary Jansen, Gerda Methorst and Ad Kerkhof offered to act as guest editors for a special issue on this topic.

Any collection of papers which attempts the task of an international overview is bound to be selective. Although the present collection is no exception in this respect, certain key themes are explored very successfully. These include the nature of the development of the discipline and the professional perspective, as revealed in the emergence of different types of training program. Added to this there is a most valuable opportunity to compare the development and application of health psychology in contrasting countries around the world. In addition to ensuring that the papers cover an appropriate range of areas, the guest editors have been particularly fortunate in obtaining contributions from a very impressive collection of authors from many countries and professional contexts.

At present health psychology holds many promises both as a research area and as an emerging profession. The planning of good quality research and of appropriately structured training programs is necessary to convert the promises into a reality. In our attempts to do this, we will need to cooperate and to learn from each other and this collection of papers provides an excellent basis for this. I am extremely grateful to the contributing authors and to Mary Jansen, Gerda Methorst and Ad Kerkhof for all their hard work.  相似文献

Although the relationship between research and clinical psychology has at times been conflicted, it has also been productive. Psychologists from both specialties have benefited from each others' work. The area of psychotherapy outcome research represents an important interface between the fields of clinical and research psychology. In an era of scarce resources and demands for accountability, there is pressure for researchers to justify the value of clinical practices. Recently, numerous articles have appeared recommending changes to the way psychotherapy research is conducted. The authors of these articles emphasize with urgency the importance of conducting and reporting research in a manner that will influence the decisions of policymakers and sanction funding for psychotherapy services. This article is an exploration of the impact of these recommendations, whose objective appears to be the promotion of psychological techniques for inclusion in clinical practice guidelines. It is argued that such recommendations may be in conflict with the philosophy and methods of science and may adversely affect public perception, perhaps leading psychologists to be seen as political lobbyists rather than clinicians and researchers.  相似文献

There has been an emphasis in the development and research literature on the participation of beneficiaries in the planning, implementation, and evaluation of projects. Initially, approaches were described as facilitating participation. However, in more recent years the term participatory has been used. As this trend has occurred there has been an increasing advocacy of the participatory approach as a prerequisite for projects. The analysis starts with an identification of the differences between participation and participatory approaches to planning and evaluation. The importance of recognizing when participation may be appropriate as opposed to more participatory approaches is outlined. Conditions for the success of participatory approaches are noted and a set of criteria are recommended. The analysis is illustrated with examples from diverse geographic and subject-matter backgrounds.  相似文献

Any attempt to elucidate the nature and mechanism of passivity phenomena, i.e., experiences that one's conscious actions or thoughts have not been 'willed' by oneself, requires an integrative philosophical-neurobiological approach. The model proposed here adopts some fundamental positions that have long been advocated by philosophers and theoretical psychologists and have now found support from functional neuroanatomy. First, we experience our actions not from the standpoint of the executive but through the perception of its effects. Second, the 'self' is not an agent of behaviour. Third, behaviour is energized and integrated by basic drives (instincts). Fourth, the view that the experience of an acting self is related to drive reduction associated with voluntary actions is perhaps less well developed. The model thus proposes that passivity phenomena are actions that are induced by the perception of salient events but that are not integrated with or conducive to the overall motivational state of the organism. It has been suggested that, following the perception of salient events, competition arises between automatic response tendencies seeking expression. The prefrontal cortex appears to play an important role not only in determining which events are to be perceived but also which of the corresponding response dispositions is to be selected and actualized in overt behaviour. Thus, action selection is the outcome of competition between response tendencies in the context of prefrontal biasing signals that represent drives and strivings for goals. Action selection may be uncoupled from drives and strivings as a result of a lowering of the threshold for action selection--as is suggested to be the case in schizophrenic passivity phenomena--or due to disconnection from prefrontal regions--as may be the case in the alien limb syndrome.  相似文献

Reflective practice is recognised as an integral part of being a highly skilled and successful health care professional. Many benefits have been identified from being a reflective practitioner including the opportunity for critical thinking, growing self-awareness and supporting individual resilience. There is a growing body of literature recognising the negative emotional impact that caring for children with cancer and blood disorders can have on health professionals. Currently there is an emerging interest in a more strengths-based approach focused on maintaining staff wellbeing. Resilience has been suggested as a framework for coping and maintaining wellbeing in areas, like children’s oncology and has been used as a term to describe the ‘surviving’ health professional. This paper explores the first author’s (GA) experiences of being a children’s oncology nurse and paediatric palliative care nurse specialist in the context of existing empirical and theoretical literature, with a particular focus on how GA developed resilience. Reflective examples of practice are used within the context of themes identified from a recent literature review exploring how resilience is defined within empirical literature.  相似文献
