The experiences of mothers of adult offspring with Angelman, Cornelia de Lange, or Cri du Chat syndrome have not been previously
explored in research. The current study focuses on experiences with social and medical services and the impact the rareness
of an adult offspring’s syndrome has on the experiences of mothers. Eight mothers of adults with Angelman, Cornelia de Lange,
or Cri du Chat syndrome were interviewed. Thematic Content Analysis was used to interpret the interviews. Four themes emerged
from the analysis: (i) The rarity of their offspring’s syndrome, (ii) Uneven medical and social care service provision, (iii)
The inertia of social care services, and (iv) Mothers as advocates. Mothers felt that the rareness of their offspring’s syndrome
did not affect experiences with social care services, but did affect access to medical services and some aspects of day-to-day
living. Accessing appropriate social care services was reported to be a lengthy and complex process. These data may help inform
care service providers about how best to support adults with rare genetic syndromes and their families. 相似文献

This paper obtains the weak completeness and decidability results for standard systems of modal logic using models built from
formulas themselves. This line of work began with Fine (Notre Dame J. Form. Log. 16:229–237, 1975). There are two ways in
which our work advances on that paper: First, the definition of our models is mainly based on the relation Kozen and Parikh
used in their proof of the completeness of PDL, see (Theor. Comp. Sci. 113–118, 1981). The point is to develop a general model-construction
method based on this definition. We do this and thereby obtain the completeness of most of the standard modal systems, and
in addition apply the method to some other systems of interest. None of the results use filtration, but in our final section
we explore the connection. 相似文献

Postdeployment Suicide Risk Increases Over a 6‐month Period: Predictors of Increased Risk among Midwestern Army National Guard Soldiers 下载免费PDF全文

National Guard (NG) soldiers returning from deployments in Iraq and Afghanistan were surveyed at 6 and 12 months following their return (N = 970). The overall prevalence of suicide risk at 6 and 12 months following their return was assessed, as were changes in suicide risk among soldiers initially at high or low risk. Factors associated with changes in risk were assessed. The percentage of NG soldiers with high suicide risk increased from 6.8% at 6 months to 9.2% at 12 months (odds ratio = 1.7, p = .02). In the 882 soldiers initially at low risk, 5.9% (52/882) became high risk at 12 months; in the 64 soldiers initially at high risk, 46.9% (30/64) became low risk at 12 months. Initial levels of depressive symptoms were predictive of changing to high risk; this association appeared to be partially explained by soldier reports of increased search in the meaning in life and higher levels of perceived stress. Because suicide risk increases over the first 12 months, continued risk assessments during this time period should be considered. Supporting soldiers to find meaning in their life after deployment and enhancing their capacity to cope with perceived stress may help prevent increases in suicide risk over time. 相似文献

In the present issue, we critically review the influentialsuppression model of the octave illusion (Chambers, Mattingley, & Moss, 2004). In a rejoinder to our article, Deutsch (2004b) defends the utility
of the suppression model. Here, we respond to Deutsch’s arguments, many of which are based on criticisms of our recent experimental
report (Chambers, Mattingley, & Moss, 2002). We argue that Deutsch’s criticisms of this previous investigation are unfounded
and that her defense of the suppression model fails to account for the most important weaknesses of this theory. We conclude
that the suppression model remains inadequate as an explanation of the octave illusion. 相似文献

The objective of the study was to examine the longitudinal relation between early school-age measures of maternal psychosocial distress, quality of mother-child interactions, and child attachment behavior, and behavior problem profiles in middle childhood using a multi-informant design. Participants were 243 French-speaking mother-child dyads (122 girls) who were part of an ongoing longitudinal project. Maternal psychosocial distress was assessed when children were between 4 and 6 years of age. Mother-child interactive quality and attachment patterns were observed at age 6 during a laboratory visit. At age 8.5, externalizing and internalizing problems were assessed using mother and child reports. Results show that maternal psychosocial distress predicted later social adaptation reported by the child through the mediation of mother-child interactions. Analyses also revealed that higher maternal psychosocial distress and controlling attachment patterns, either of the punitive or caregiving type, significantly predicted membership in both child internalizing and externalizing clinical problem groups. Lower mother-child interactive quality, male gender, and child ambivalent attachment were also predictors of externalizing clinical problems. 相似文献

If the question “What is a gene?” proves to be worth asking it must be able to elicit an answer which both recognizes and address the reasons why the concept of the gene ever seemed to be something worth getting excited about in the first place as well analyzing and evaluating the latest develops in the molecular biology of DNA. Each of the preceding papers fails to do one of these and sufferrs the consequences. Where Rolston responds to the apparent failure of molecular biology to make good on the desideratum of the classical gene by veering off into fanciful talk about “cybernetic genes,” Griffiths and Stotz lose themselves in the molecular fine print and forget to ask themselves why “genes” should be of any special interst anyway. 相似文献

This study examined correlates of attachment at age 3 to further validate preschool separation-reunion measures. Three-year-olds (N = 150) and their mothers participated in a separation-reunion protocol, the Preschool Attachment Classification System (PACS: J. Cassidy & R. S. Marvin with the MacArthur Working Group on Attachment, 1992), and a mother-child interaction session during a laboratory visit. Mothers also completed psychosocial measures and, along with teachers, evaluated child behavior problems. The secure and disorganized groups received, respectively, the highest and lowest interaction scores. Disorganized children showed a higher level of teacher-reported externalizing and internalizing problems than did secure children. Mothers of insecure children reported higher child externalizing (all insecure groups) and internalizing (avoidant group) scores, more personal distress related to emotional bonding (disorganized group), childrearing control (ambivalent group), and child hyperactivity (avoidant group). Results strongly support the validity of the PACS as a measure of attachment in 3-year-olds. 相似文献
