Forgiveness, acceptance and the matter of expectation   总被引:1,自引:0,他引:1  
In this paper, the author argues for a dynamic conceptualization of forgiveness during psychoanalysis. The trauma of failed expectations in intimate relationships is narcissistically dislodging. When legitimate expectations in relationships are not met, forgiveness becomes a challenge for ego to restore the lost narcissistic balance through the resumption of a significant internal bond. The author argues that the ending of any successful analysis is marked by three possibilities regarding the patient's relationship to significant others and his traumas: in cases where the relationship was marked by minimal expectations, one simply learns to accept the wrongdoer without ever feeling the need for forgiveness; in cases where a relationship was marked by high expectations, the patient can learn to accept the trauma without the will or need to forgive its perpetrator. However, even with the painful frustration of high expectations in an intimate relationship, the patient can come to forgive his wrongdoer if there remains enough of a positive internal bond to be salvaged. The developmental roots of such forgiveness, as well as the addictive characteristics of 'nursing a grudge' and the conversion of the qualitative mode of seeking fulfillment into a quantitative one, are further investigated.  相似文献

In secondary analyses of National Institute of Child Health and Human Development Study of Early Child Care and Youth Development data, multiple indicators of quality (caregiver wages and turnover; child/staff ratio; caregiver education and professionalism; positive caregiving) were compared between child care centers by sector (for-profit/nonprofit) and subsector (for-profit independent/chain, nonprofit church/nonchurch) at multiple points from infancy through prekindergarten. Nonprofit centers evidenced higher caregiver wages and education at most ages and better quality child/staff ratios, turnover, caregiver professionalism, and positive caregiving for toddlers and preschoolers. Subsector differences in preschool classrooms were more complex. In general, quality was higher in nonprofit non-religiously affiliated centers, intermediate in nonprofit religiously affiliated and for-profit independent centers, and lower in for-profit chains, but differences were not found on every indicator or between every group. Further, for-profit chain status predicted lower quality positive caregiving, controlling for family characteristics, staff, and structural quality, at 54 months, but not 36 months. Results support and extend prior research by controlling for family characteristics. Policy implications regarding supply- and demand-side quality-improvement strategies that address market competition and parent choice across subsectors are discussed.  相似文献

This paper uses a simulation approach to investigate how different attribute weighting techniques affect the quality of decisions based on multiattribute value models. The weighting methods considered include equal weighting of all attributes, two methods for using judgments about the rank ordering of weights, and a method for using judgments about the ratios of weights. The question addressed is: How well does each method perform when based on judgments of attribute weights that are unbiased but subject to random error? To address this question, we employ simulation methods. The simulation results indicate that ratio weights were either better than rank order weights (when error in the ratio weights was small or moderate) or tied with them (when error was large). Both ratio weights and rank order weights were substantially superior to the equal weights method in all cases studied. Our findings suggest that it will usually be worth the extra time and effort required to assess ratio weights. In cases where the extra time or effort required is too great, rank order weights will usually give a good approximation to the true weights. Comparisons of the two rank-order weighting methods favored the rank-order-centroid method over the rank-sum method. © 1998 John Wiley & Sons, Ltd.  相似文献

In this preliminary, intrasubject study (N = 8), we examined the effects of communication skills training and the use of memory books by Nursing Assistants (NAs) on the social ecology of a nursing home. Through inservice and on-the-job training, NAs were taught to use communication skills and memory books during their interactions with residents with mild to moderate cognitive impairment (Mini Mental Status Examination, M = 16.25), but relatively intact communication abilities. An abbreviated staff motivational system called Behavioral Supervision (Burgio and Burgio, 1990. Int. J. Aging Hum. Deve. 30: 287–302.) was attempted to encourage performance of these skills on the nursing units. Results showed that, regardless of sporadic implementation of the intervention by nursing staff, the intervention improved communication between staff and residents during care routines, increased the amount of time other residents and visitors spent talking with target residents, and increased the rate of positive statements made by the target residents and others in their immediate environment. Results are discussed in terms of limitations of the staff motivational system and modifications made to the system in a larger ongoing intervention trial.  相似文献
