Hamartoses (HM) are defined as disorders involving nonneoplastic tissue overgrowth. Studies have examined the neuropsychological profiles of children with common HM, such as neurofibromatosis type 1. Limited information is known regarding neuropsychological profiles of rare HM such as Osteochondromatosis Syndrome (OS) and Klippel-Trenaunay Syndrome (KTS). The current investigation is, to our knowledge, the first attempt to define the cognitive phenotypes in two boys with OS and KTS. Results revealed significantly greater impairments involving sensorimotor and visuospatial skills, while verbal memory and language skills appeared relatively preserved. Significant neurobehavioral problems and marked social difficulties were evident. These findings suggest that these syndromes are on a Nonverbal Learning Disorder (NLD) continuum, with varying degrees of severity. 相似文献

The Catholic Church is built, on the one hand, upon a hierarchical structure and vertical relationships, with stratified duties, centered around an organizational culture which is based on strict obedience to institutional directives and which has a monopoly on the administration of the goods and resources concerning salvation. On the other hand, since the Second Vatican Council, the Church has proposed to incorporate lay people into God's Kingdom, a development which represents an opening to the active participation of diverse groups and a redistribution of access to the goods of salvation. Analysts may take a position one way or the other regarding their definition of the Church, and some even state the existence of a dominant church and a people's church. In contrast to both these perspectives, this paper looks at a methodological and theoretical model for studying diversity within Catholic unity. The model is based on the concept of the 'transversalized institution' as it is applied to the way in which Guadalajara's diocese functions. 相似文献

We studied 205 low-income families, using the Family Needs Scale (FNS). Factor analysis of the FNS data resulted on a 7-factor solution with high internal consistency within the various subscales. We provide normative scores based on the factor structure of the FNS. A total of 53 parents completed the FNS on two occasions with an average of four weeks between these two ratings. In general, the test-retest reliabilities were low to moderate. A total of 61 pairs of parents independently rated their families with the FNS. Again, agreement between raters was low to moderate. Several factors that may have detracted from better test-retest and interrater reliability were identified. Our data point to the need for more psychometric studies with the FNS. 相似文献

网络家庭以夫妻生活的无性化、夫妻关系的非对偶性、夫妻性别的可转换性和现实人伦关系的消匿等四大特征兴起于现代社会.其兴起的社会根源在于家庭功能的弱化、道德观念的宽容性增加和网络技术能力的增进.其中交织着网络空间的扩张与社会交往的挤压、心理压力的剧增与情感宣泄的不畅、婚姻需求的发展与现实条件的匮乏三大矛盾.网络家庭的兴起造成了家庭观念的变异、婚姻行为的变化和现实家庭的危机三大影响. 相似文献

短尾猴和恒河猴同是猴科猕猴属中两个不同的物种。从习性学的观点看,它们的社会行为模式应是大同而小异的。作者通过对生活在自然栖息地和实验笼内短尾猴所观察到的行为模式,同文献中已公认的恒河猴的行为模式进行比较后发现,这两种动物的社会行为模式虽然在基本上是相似的,但也有明显的差异。有的是行为模式相同,社会含意不尽相同;有的是社会含意相同,模式不同;也有的模式只是短尾猴有,而恒河猴没有。本文把初步观察到的7种不同情况列出。 相似文献
