This study examined the effects of maternal employment and separation anxiety on maternal interactive behavior and infant attachment. 73 mother-infant pairs participated in a laboratory free-play session when infants were 5 and 10 months of age and in the Strange Situation when the infants were 18 months of age. Maternal feelings about being separated from her infant were assessed by questionnaire at 5 months. Employed mothers returned to work before the infants' fifth month, and nonemployed mothers did not work outside the home through their infants' tenth month. Employed mothers who reported high levels of separation anxiety were more likely to exhibit intrusive behaviors at 10 months. While employment was not directly related to attachment, we found infants of high-anxiety employed mothers to develop anxious-avoidant attachments. The results suggest that maternal separation anxiety and interactive style may be important mediators between employment and later infant outcome.  相似文献

The purpose of this national survey was to determine whether pretenured counselor educators receive research mentorship, and if so, what instructional and relational factors occur within that relationship. Pretenured counselor educators in counselor education programs accredited by the Council for Accreditation of Counseling and Related Educational Programs were surveyed (N = 269). The 139 respondents (51.7% response rate) indicated that most (n / 107) pretenured counselor educators receive research mentorship. The relationship(s), most often described as cooperative (n / 84) and open (n / 70), focused primarily on navigation of promotion and tenure (n / 87) and generating refereed publications (n / 95) and presentations (n / 72).  相似文献

Oral Cancer is one of the five leading sites of cancer in Indian population. The circulating immune complexes were investigated in 100 serum samples of 60 oral cancer patients having different grades of the disease and 40 patients with precancerous lesions obtained from Nair Hospital Dental collage, Mumbai. The results obtained were compared with those of group of 40 healthy blood donors. Elevated levels of Circulating Immune Complexes were observed in oral cancer patients and patients with oral precancerous lesions. 92% positive samples were observed in well differentiated squamous cell carcinoma whereas 100% positive samples were observed in both moderately and poorly differentiated squamous cell carcinoma. Oral leukoplakia and oral submucous fibrosis showed 15% and 90% positivity respectively. Increased level of Circulating Immune complexes in high grade tumor suggest that Circulating Immune complexes is likely to contribute in evaluating the degree of malignancy, but follow up study is needed to draw any conclusion regarding it's prognostic role  相似文献

Courses: Rhetorical Criticism, Persuasion, Rhetoric and Architecture, Visual Rhetoric.

Objectives: This single class activity is designed to raise student awareness about the rhetorical nature of architecture and campus planning; to shift student perceptions away from taking their physical surroundings as “a given” and toward seeing them as the product of strategic human choices and decision making; to foster a spirit of curiosity about how buildings can influence our emotions and behavior; and to reduce student uncertainty about unfamiliar course content.  相似文献

This study addresses the health of young children and how to safely and effectively care for children with diarrhea in the home and in early child care settings. A baseline survey showed the prevalence of oral rehydration solution (ORS) usage at last diarrhea bout to be low. An educational workshop was developed to train parents and child care professionals on how to properly manage young children with diarrhea and reduce the risk of diarrhea spread at home and in early childhood settings. Specific intervention activities are discussed and program activities, including specially designed materials for mixing homemade ORS are described. A comparison of pre- and postintervention data indicates substantial gains in knowledge among both urban and rural populations. Implications of research findings are discussed along with suggestions for future research.  相似文献

Intake of a 0.15% saccharin solution was suppressed when it was followed by a 32% sucrose solution in brief daily pairings. With equal access durations to the two solutions, intervals of intermediate duration (2 or 3 min) produced a larger contrast than more extreme intervals (1 or 10 min). There was no evidence of inhibition of delay with the 10-min interval (Experiments 1A and 1B). When access times were asymmetrical, longer access time to the first solution reduced contrast, whereas longer access time to the second solution enhanced contrast (Experiment 2). Contrast was greater when the two solutions were presented at consistent and separate spatial locations than when location was changed randomly or when both solutions were presented in sequence at the same location. However, a degree of contrast occurred in all conditions (Experiment 3). Experiment 4, conducted with the solutions in opposite arms of a T-maze, showed that anticipatory approach to the location correlated with the 32% sucrose solution developed prior to lick suppression on the saccharin solution. However, within daily sessions, there was a reliable increase in contrast without correlated changes in anticipatory-approach behavior. Access-time effects were attributed to altered reward values, whereas spatial-separation effects suggest that goal-directed responses contribute to, but do not cause, anticipatory contrast.  相似文献
