This article investigates the guardianship of fatherless children (orphans) in one of the most important Jewish communities of the thirteenth-century realms of Aragon, the aljama of the town of Perpignan. After reviewing some ideals of Solomon ben Abraham ibn Adret of Barcelona, as expressed in his responsa, the article focuses on documents of practice. This documentary basis includes royal charters, Latin wills of Jewish testators, and 148 unedited transactions generated by eighteen panels of guardians between 1266 and 1286, described in an analytical table at the end of the article. The practical evidence reveals that guardians usually served as a group, panels comprised close relatives of the wards and men who were distinguished in their community through official service. Case studies expose the dynamics within these panels and establish that the orphans' widowed mother usually acted as the group's leader. A comparison with her Christian counterpart places the rights and responsibilities of the Jewish widowed mother guardian into relief. Although not autonomous, Jewish widowed guardians were highly effective caretakers of their fatherless children. The idealized view of the Jewish widow held by her medieval contemporaries as helpless and in need of special care from the men of her community enabled already capable widows to benefit from the financial aid of community leaders who otherwise might not have been so keen to foster these women's legal and financial agency.  相似文献

The purpose of this study was to determine the influence of personality disorders on perceived health status, self-efficacy for management of the chronic illness, and physician perception of patient health. A total of 607 patients with self-identified chronicillness(es) volunteered to participate in the study. Out of this sample, 147 had collaborative physician data indicating a chronic illness. The final sample was 143 due to incomplete data. Results suggested that maladaptive personality characteristics, as measured by the Short-Form of the Coolidge Axis II Inventory (SCATI), were related to a number of important factors that influence self-management of chronic illnesses. When the personality constellations were broken into 3 groups (normal, subclinical, and clinical) significant differences were found on the 3 groups of dependent variables (Subjective Health, Self-Efficacy, Physician Appraisal) for the different personality disorders. These data provide useful information on several factors that influence effective disease management. Clinical implications and directions for future research are provided.  相似文献

Adolescent ego-development trajectories were related to close-relationship outcomes in young adulthood. An adolescent sample completed annual measures of ego development from ages 14 through 17. The authors theoretically determined and empirically traced five ego-development trajectories reflecting stability or change. At age 25, the sample completed a close-relationship interview and consented for two peers to rate the participants'ego resiliency and hostility. Participants who followed the profound-arrest trajectory in adolescence reported more mundane sharing of experiences, more impulsive or egocentric conflict-resolution tactics, and less mature interpersonal understanding in their young adult relationships, and their young adult peers described these participants as more hostile. Participants who attained or maintained higher levels of ego development in adolescence reported more complex sharing of experiences, more collaborative conflict-resolution strategies, and greater interpersonal understanding, and their young adult peers rated them as less hostile and as more flexible.  相似文献

Dissociative disorders that are believed to develop from childhood sexual abuse are often considered to include amnesia for childhood events, particularly the events that involve the abuse itself. One unresolved issue is the extent to which memory recovery attempts can contribute to claims of having amnestic symptoms. Experiments with undergraduate subjects reveal that requiring more reports of childhood events will increase judgments of having poorer memory of one’s childhood. The results are consistent with the use of heuristics when one is reasoning under conditions of uncertainty, as experienced difficulty in remembering more experiences is attributed to the incompleteness of childhood memory. The findings challenge the validity of reports of childhood amnesia that follow memory recovery attempts.  相似文献

To examine possible effects of iron supplementation on the intelligence of young adolescents, iron supplements and placebos were given daily for 16 weeks to two matched groups of 208 and 205 12–15-year-olds. Iron status before the trial began was assessed by the measurement of serum ferritin and haemoglobin levels. In the sample considered as a whole, the iron supplementation had a small but nonsignificant effect on IQ, but those who were iron deficient, with serum ferritin levels of 12 ng/ml and below, showed a statistically significant IQ gain of 5.8 IQ points, as compared with a matched control group given placebos.  相似文献

A recognition memory task was used to determine whether the search set is reduced by cueing subject to forget a part of the input. Correct recognition reaction time was used to infer the size of the search set. The principal results were that RT on forget trials was faster than RT on remember trials and that RT was fastest when the forget cue was presented at the outset of the trial rather than after the material had been presented. These findings are generally consistent with the hypothesis that selective search is responsible for the enhancement of recall produced by forget instructions in earlier studies.  相似文献
