Social system responses to Huntington disease 总被引:4,自引:0,他引:4
Huntington disease (HD) is an adultonset, genetic disorder with major psychosocial implications. Although many of the psychiatric symptoms of the disorder have been attributed to the HD gene, systems factors may also account for the disorder's manifestations. Three illustrative issues--patient preselection, the denial of symptom onset, and suicide induction--are discussed from the vantage point of family systems thinking. Recently developed capacity for presymptomatic testing of HD despite the current absence of treatment or cure makes it likely that family therapists increasingly will be involved in clinical work with individuals and families in which HD occurs. 相似文献

Since the early days of physics, space has called for means to represent, experiment, and reason about it. Apart from physicists, the concept of space has intrigued also philosophers, mathematicians and, more recently, computer scientists. This longstanding interest has left us with a plethora of mathematical tools developed to represent and work with space. Here we take a special look at this evolution by considering the perspective of Logic. From the initial axiomatic efforts of Euclid, we revisit the major milestones in the logical representation of space and investigate current trends. In doing so, we do not only consider classical logic, but we indulge ourselves with modal logics. These present themselves naturally by providing simple axiomatizations of different geometries, topologies, space-time causality, and vector spaces. 相似文献

We propose an externalist understanding of sex that builds upon extended and distributed approaches to cognition, and contributes to building a more just, diversity‐sensitive society. Current sex categorization practices according to the female/male dichotomy are not only inaccurate and incoherent (attributing nonreproductive properties to differences in vaguely defined reproductive roles), but they also ground moral and political pressures that harm and oppress people. We argue that a new understanding of sex is due, an understanding that would acknowledge the variability and, most important, the flexibility of sex properties, as well as the moral and political meaning of sex categorization. We propose an externalist account of sex, elaborating on extended and distributed approaches to cognition that capitalize on the natural capacity of organisms to couple with environmental resources. We introduce the notion of extended sex, and argue that properties relevant for sex categorization are neither exclusively internal to the individual skin, nor fixed. Finally, we spell out the potential of extended sex to support an active defense of diversity and an intervention against sex‐based discrimination. 相似文献

In their seminal paper, Edwards and Parry (1993) presented the polynomial regression as a better alternative to applying difference score in the study of congruence. Although this method is increasingly applied in congruence research, its complexity relative to other methods for assessing congruence (e.g., difference score methods) was one of the main claims against its use. The objective of this work is to gain additional insight into the use of polynomial regression in the area of social and behavioral sciences. First, we elaborate on the meaning and the inference based on the coefficients obtained by applying polynomial regression and explain the mathematical terms that are used to describe response surfaces. Then, we introduce additional inference methods and illustrate their application on a real-life example from the area of supportive exchanges using data collected by the Smithers Institute at Cornell University (supported by the National Institute on Alcohol Abuse and Alcoholism). Our work is aimed to provide a guide to researchers who apply polynomial regression in order to assess the effect of congruence between two constructs and enable better understanding and interpretation of the results obtained. 相似文献

Evidence is accumulating for the transgenerational effects of maternal stress on offspring. A particular increasing concern is the possible transgenerational effects of community exposure to war and terror. Here, 107 mothers that had been exposed to war, were assessed with their 3 year old children (52 % girls) who had been conceived after the end of the war, and thus never directly exposed to war. The circumscribed nature (missile bombardment) and temporal limits (34 days) of the tragic 2006 Lebanon war in the north of Israel, affords a unique methodological opportunity to isolate an epoch of stress from preceding and subsequent normal life. We find that war experience engenders higher levels of mothers’ separation anxiety, lower emotional availability in mother-child interaction, and lower levels of children’s adaptive behavior. The novelty of these findings lies in documenting the nature and strength of transgenerational effects of war-related stress on offspring that were never exposed. In addition, because these effects were obtained after 4 years of a continuing period of normality, in which the children were born and raised, it suggests that an extended period of normality does not obliterate the effects of the war on mother and child behavior as assessed herein. Despite the study limitations, the results are indicative of persisting transgenerational effects of stress. 相似文献

Compared with full-terms, preterm individuals are more at risk from infancy to adulthood for developing internalizing symptoms. Early maternal interactive behavior, especially maternal sensitivity, has been found to be a resilience factor in the developmental outcome of preterm children. The present longitudinal study aimed at examining whether early interactive parenting behaviors have a long term impact on the internalizing symptoms of preterm-born young adolescents. A total sample of 36 very preterm and 22 full-term children participated in an 11-year follow-up study. Maternal interactive behavior was assessed during a mother–infant interaction when the infant was 18 months old. At 11 years, internalizing symptoms were assessed with the Child Behavior Checklist (CBCL). Hierarchical regression analyses revealed that the interaction between groups (preterm/full-term) and maternal sensitivity at 18 months significantly explained CBCL internalizing symptoms at 11 years (β = ?0.526; p < 0.05). Specifically, although prematurity was related to internalizing problems, preterm children with higher maternal sensitivity did not differ from their full-term-born peers on the CBCL internalizing problems domain. These results suggest that maternal sensitivity is a long-term resilience factor preventing the development of internalizing problems at early adolescence in very preterm individuals. 相似文献

This study longitudinally examined the production of pointing in four Spanish 1-year-old and four Spanish 2-year-old children in interactive situations with their mothers at home over the course of one year. Three aspects were analyzed: a) the functions of the pointing gesture, their accurate comprehension by the interlocutor (mother or child), and their order of emergence in the child; b) whether or not there were differences in the production of pointing according to who initiated the interaction; and c) whether maternal and child speech were related to maternal and child pointing production. The results showed that the pointing function of showing is the most frequent for both children and mothers from groups 1 and 2, and the first to emerge followed by the informing, requesting object, requesting action, and requesting cooperation functions. The accuracy with which these intentions were comprehended was found to be very high for both mother and child. Pointing production was greater when the speaker initiated the interaction than when the other person did, indicating that gestures follow the turn-taking system. Finally, the production of pointing to showing in children and mothers was found to be related to maternal and child speech, while pointing to request cooperation triggered the process of joint activity between mother and child. 相似文献

Thirty‐three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow‐up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991 ). At 4 months, mother–infant play interaction was observed and coded according to the CARE‐index (P.M. Crittenden, 2003 ); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978 ) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long‐term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants. 相似文献
