Economic well-being and children's social adjustment: the role of family process in an ethnically diverse low-income sample   总被引：1，自引：0，他引：1

Using latent variable structural equation modeling, a family economic stress model that links economic well-being to child well-being in an ethnically diverse, low-income sample of 419 elementary school-age children was evaluated. The sample was 57% African American and 28% Hispanic, and most families were headed by single mothers. The results provided support for the position that family process is a critical mediator of the effects of economic hardship on children's social adjustment. Lower levels of economic well-being, and the corollary elevated perceptions of economic pressure indirectly affected parenting behavior through an adverse impact on parental psychological well-being. Distressed parents reported feeling less effective and capable in disciplinary interactions with their child and were observed to be less affectionate in parent-child interactions. In turn, less than optimal parenting predicted lower teacher ratings of children's positive social behavior and higher ratings of behavior problems. Multiple-group analyses revealed that the pathways by which economic hardship influences children's behavior appear to operate similarly for boys and girls, and for African American and Hispanic families.  相似文献   

Children with epilepsy in school: Special service usage and assessment practices     

David L. Wodrich  Allen M. Kaplan  William M. Deering 《Psychology in the schools》2006,43(2):169-181

Special services usage and related assessment procedures were investigated for 50 students with epilepsy. Fifty‐six percent of students with epilepsy received special education services, with mental retardation designation and self‐contained placement common, especially among individuals with epilepsy plus a coexisting neurological diagnosis. Sixteen percent of participants had an “other health impairment” designation, and several of these were deemed eligible in at least one other special education category. The majority of students who had been evaluated were administered IQ, adaptive behavior, speech/language, and sensorimotor components, whereas few were assessed for executive or memory functions. Little information about antiepileptic drugs, their effects, or the actual manifestation of students' seizures appeared in special services school documents. Additional empirical information regarding services for children with chronic health conditions, such as epilepsy, is necessary to improve school psychologists' practice. © 2006 Wiley Periodicals, Inc.

Circulating peptide and steroid hormone levels in patients with breast cancer     

Lakshmi Krishnamoorthy  Elizabeth Zachariah  P. G. Ramaswamy  N. Anantha 《Indian journal of clinical biochemistry : IJCB》1994,9(1):37-39

Circulating levels of gonadotropins (FSH,LH), prolactin (PRL), estradiol and progesterone were measured by radioimmunoassay in the sera of 60 patients with histopathologically proven breast cancer. 30 patients belonged to the post and 30 to the premenopausal group. 30 healthy women, 15 each in the pre and post menopausal groups served as controls for the study. Prolactin was elevated in 33% and 26% of pre and post menopausal breast cancer patients respectively. Lower levels of estradiol and progesterone were observed during the luteal phase of the menstrual cycle in premenopausal breast cancer patients. Among postmenopausal patients with breast cancer, LH was elevated in 32%, FSH in 15% and estradiol in 30% of the patients studied.  相似文献   

Can creative destruction be destroyed? Military IR&D and destruction along the value-added chain     

Allen Kaufman  Mark Brumer 《Research Policy》2003,32(9):1537-1554

We elaborate a supply chain innovation matrix that can be applied to both commercial and military supply chains. By shifting the analysis from a focal firm to industry structure, we argue that the market structure of the entire supply chain functions as a major moderating variable in determining both the timing and adoption of innovations, both for commercial and military markets. We extend work on supply chain resource dependency by drawing a distinction between market-structure-induced resource dependency and supplier over-reliance on a customer in a competitive market. This has policy implications for the organization of military industrial research and development (IR&D). Joint service research and development (Jointness) will certainly bring about innovation, but it will be incremental, reinforcing established military hierarchies. Policy makers may need to add this probable consequence when comparing Jointness and inter-service rivalry. The cost savings inherent in Jointness may unwittingly sustain a military force unready for fighting the next war.  相似文献   

Librarians collaborate successfully with nursing faculty and a writing centre to support nursing students doing professional doctorates     

Matthew Bernstein  Linda Roney  Meredith Kazer  Elizabeth H. Boquet 《Health information and libraries journal》2020,37(3):240-244

This study explores how a three‐way collaboration between a University library, writing centre and faculty created avenues of training and support for students within a Doctor of Nursing Practice (DNP) program in an American University. The role of each partner involved in the collaboration is discussed alongside the profile of the DNP students. Lesson planning and classroom techniques for DNP information literacy classes are described and feedback from the partners and the students are discussed. The study confirms that collaboration is effective in improving research and writing skills. D.I.  相似文献   

Medical librarian 2.0     

Connor E 《Medical reference services quarterly》2007,26(1):1-15

Web 2.0 refers to an emerging social environment that uses various tools to create, aggregate, and share dynamic content in ways that are more creative and interactive than transactions previously conducted on the Internet. The extension of this social environment to libraries, sometimes called Library 2.0, has profound implications for how librarians will work, collaborate, and deliver content. Medical librarians can connect with present and future generations of users by learning more about the social dynamics of Web 2.0's vast ecosystem, and incorporating some of its interactive tools and technologies (tagging, peer production, and syndication) into routine library practice. doi: 10.1300/J115v26n01_01.  相似文献   

Addressing sexuality and pregnancy in childbirth education classes     

Allen L  Fountain L 《The Journal of perinatal education》2007,16(1):32-36

A positive, nonjudgmental, and informed approach to sexual health during pregnancy promotes acceptance of the normal functioning of women's bodies. It also encourages the development of close and supportive relationships that are so essential during pregnancy and birth. Common concerns do not need to become problems. Concerns include issues of libido, positioning, and preterm labor or fetal health, as well as myths and cultural attitudes. Childbirth educators can use tools such as the PLISSIT model to approach the topic of sexuality during pregnancy. In addition, opportunities are available in every childbirth class to acknowledge or ignore sexual issues. Perinatal educators who take responsibility for addressing this often-taboo topic can enhance women's feelings of safety and their confidence in normal birth.  相似文献   

Income is not enough: incorporating material hardship into models of income associations with parenting and child development   总被引：2，自引：0，他引：2  

Gershoff ET  Aber JL  Raver CC  Lennon MC 《Child development》2007,78(1):70-95

Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention.  相似文献   

Processes of language acquisition in children with autism: evidence from preferential looking     

Swensen LD  Kelley E  Fein D  Naigles LR 《Child development》2007,78(2):542-557

Two language acquisition processes (comprehension preceding production of word order, the noun bias) were examined in 2- and 3-year-old children (n=10) with autistic spectrum disorder and in typically developing 21-month-olds (n=13). Intermodal preferential looking was used to assess comprehension of subject-verb-object word order and the tendency to map novel words onto objects rather than actions. Spontaneous speech samples were also collected. Results demonstrated significant comprehension of word order in both groups well before production. Moreover, children in both groups consistently showed the noun bias. Comprehension preceding production and the noun bias appear to be robust processes of language acquisition, observable in both typical and language-impaired populations.  相似文献   

Children with autism illuminate the role of social intention in word learning   总被引：2，自引：0，他引：2  

Parish-Morris J  Hennon EA  Hirsh-Pasek K  Golinkoff RM  Tager-Flusberg H 《Child development》2007,78(4):1265-1287

To what extent do children with autism (AD) versus typically developing children (TD) rely on attentional and intentional cues to learn words? Four experiments compared 17 AD children (M age=5.08 years) with 17 language- and 17 mental-age-matched TD children (M ages=2.57 and 3.12 years, respectively) on nonverbal enactment and word-learning tasks. Results revealed variability in all groups, but particularly within the AD group. Performance on intention tasks was the most powerful predictor of vocabulary in the AD group but not in the TD groups. These findings suggest that word learning cannot be explained exclusively by either attentional or intentional processes, and they provide evidence of a special role for intentional understanding in the vocabulary development of AD children.  相似文献
