Although fathers perpetrate a significant proportion of child maltreatment, the intervention needs of abusive and neglectful fathers have not been adequately addressed or researched. This paper argues that well-designed treatment has the potential to benefit men, their children, and their families. However, the treatment needs of maltreating and at-risk fathers are unique, and programs must be designed accordingly. Based on the integration of parenting, child abuse, change promotion, and batterer treatment literatures, five principles to guide intervention with maltreating fathers are advanced: (a) overly controlling behavior, a sense of entitlement, and self-centered attitudes are primary problems of abusive fathers; thus, the development of child-management skills should not be an initial focus of intervention; (b) abusive fathers are seldom initially ready to make changes in their parenting; (c) fathers' adherence to gender-role stereotypes also contributes to their maltreatment of children; (d) the relationship between abusive fathers and the mothers of their children requires special attention; and (e) because abusive fathers have eroded children's emotional security, the need to rebuild trust will affect the pace of change and potential impact of relapse on the child. These principles are contrasted with the supportive and child-management goals of conventional group parenting programs, and the implications for providing service to fathers are considered. 相似文献
In much of the literature to date, the definition of climacteric symptoms has been based largely upon women who present for medical treatment of symptoms. It is already well recognised that patients (of all ages and both sexes) presenting for medical treatment tend to report themselves as suffering from more life stresses and from more neurotic symptoms than people in the general population. Life stress and adequacy of coping may thus be important factors in the incidence of symptomatology at the climacteric, as at any other time of life. This study therefore investigated the proposal that post-menopausal women who present for treatment at menopause clinics suffer from more life stresses and more neurotic symptoms than post-menopausal women in the general pupolation.
It was found that patients did indeed suffer from more psychosocial stress, measured in terms of life events, clinical depression and anxiety scales and a rating scale based on a clinician's judgements of ongoing psychosocial stress, vulnerability and adequacy of coping. Patients also suffered from significantly more symptoms than non-patients, not only psychological, but also hypothalamic and metabolic symptoms. However, the incidence of hot flushes and vaginal atrophy was the same in both groups. The stress/coping rating was the measure which correlated most highly with the psychological symptoms reported by subjects as symptoms of menopause. Life events and clinical stress measures were more consistently related in the non-patient group, indicating possible intervening variables (such as hormone imbalance) in this relationship in the patient group. 相似文献
The capacity of bone marrow-derived surface immunoglobulin-positive (sIg+) human and mouse immature B cells, generated either in vitro or in vivo, to change their light (L) chain expression, has been assayed by the number of cells which change in vitro from one type of L chain to the other type, or to no sIg at all. Immature sIg+ B cells were generated in vitro from sIg? precursor cells from human or mouse bone marrow. The immature sIg+ cells expressed RAG-1. Human sIg+ cells expressed xfr; and λ L chains in ratios between 1:1 and 3:1, whereas in mouse cells, this ratio ranged from 10:1 to 20:1. Upon reculture of the human and mouse xfr;+sIg+ cells, about half of them remained xfr;+, a quarter became λ+, and another quarter became sIg?. Between 1 and 3% expressed both xfr; and λ chains. Of the human λ+ cells, about two-thirds remained λ+, only 1 to 2% became xfr;+, while the other third became sIg?. Again, between 1 and 3% expressed both xfr; and λ L chains. These results indicate that expression of sIgM in the B cell membrane does not terminate L chain gene rearrangement, and that some order exists in xfr; versus λ gene rearrangements. Hence, human and mouse xfr;+ immature B cells can become λ+, but very few of the λ+ cells can become xfr;+, and both can become sIg?. Further, human CD10+/sIg+ xfr;+ and λ+ cells and mouse B220low/sIglow xfr;+ cells enriched from bone marrow, i.e. immature B cells differentiated in vivo, changed their Ig phenotype upon in vitro culture, but in lower frequencies. By contrast, human and mouse mature B cells did not change their L chain or Ig phenotype. Hence, at least a part of the sIg+ immature B cells in bone marrow retain the capacity to change their L chain and Ig phenotype, and this capacity is lost when they become mature, peripheral B cells. 相似文献
Somatosensory evoked potential (SEP) changes associated with selective attention were investigated. In 16 subjects, SEPs were recorded from five locations while they counted electrical stimuli to one of four randomly stimulated fingers. Sequential SEP events measured included peaks P30 (positivity at 30 msec). P45, N60, P100. N140. P190. N230, P400. Counting was associated with greater P45, P100. P190, N230, and P400 amplitudes; effects were not attributable to eye or tongue activity. Analyses designed to reveal changes associated with two conceptualized “channels” (finger class, hand) showed that the P45, P100, and P190 amplitude increases involved both channels. The P400 effect was limited to the target finger. Channel effects for N60 and N140 amplitudes resulted from decreases localized to the unattended element of one channel, suggesting “inhibition.” Latency effects involved mainly the hand channel; counted hand latencies were shorter for P30, P45, P100 and P190. The findings indicate modifications of both early and late electrocortical events with selective attention, and that changes can be of several kinds. They support the view that attention proceeds in more than one stage. 相似文献
Forty male college student volunteers were asked either to increase their diastolic pressure or their heart rate while sitting and during orthostatic stress (going from a sitting to a standing position), and half of them were also given second- to-second visual feedback for the target variable. Systolic blood pressure was also continuously recorded. Comparisons were made between baseline and voluntary control conditions, and test trials were included to examine immediate carry-over effects. With voluntary control instructions, substantial increases in tonic levels were obtained for the three cardiovascular variables in both sitting and postural change conditions. In general, the increases were significantly greater for feedback than for no-feedback conditions. Phasic effects of feedback were also observed during postural change conditions: the blood pressure troughs and the heart rate peak occurred earlier with feedback than for instructions only. Immediate transfer effects were obtained in feedback conditions only. The results were discussed in terms of concomitant effects of somatic and cognitive activities. The distinctive feedback effects on the time course of the responses suggest that a precise analysis of response patterns is needed in selecting appropriate feedback methods in the management of orthostatic hypotension. 相似文献
