The Family Walk-In Centre opened November 1978 as a pilot project at Eaton Socon in Cambridgeshire with the aims: to encourage parents to visit the centre on “their terms,” including parents who have abused or who fear they will abuse or neglect their child who may be difficult or handicapped, or because of chronic or acute family problems; further to mobilize “Self Help” groups and offer professional support. “Help” offered to the families included informal and formal group work, family casework and education in social and physical skills. Volunteer and professional support was given at the Centre and at home. Close liaison with specialist agencies was maintained to enable families to receive appropriate help. Periodic reviews and visits were made to maintain contact. An analysis of 50 families who attended the Centre between October 1979 and May 1980 was made to assess: the attendance and reattendance rate which indicated their acceptance of help offered and their motivation to use the Centre; the types of problems presented to the Centre, the types of action taken, the progress made when reviewed after three months and the degree of involvement by the volunteers. A final analysis will comprise 100 families. A preliminary summary found: significant reduction in the registration of new cases of child abuse; self-referrals exceeded significantly other modes of referral; loneliness and parenting difficulties formed the major proportion of families seeking help; 48% of families continued to attend for 3 months or more; work done centered upon discussion of parenting problems in 30% of the cases and involvement in activities with other families in 28%; 18% were assessed as showing improved child care after 3 months. The children are being monitored and will be assessed when they enter the infant school.  相似文献

The success of family planning depends on attitudes and knowledge about contraception. In this study, the correlation between ever use of contraception and health attitudes among men was assessed. 65 male participants were randomly selected from residence halls on the University of Lusaka campus in Lusaka, Zambia. Students reflected a diverse ethnic mix. The findings indicated that only 37.5% had approval from ethnic traditions for contraceptive use. Chi square tests rejected the null hypothesis that there is no relationship between the variables "ever use" and "ethnic orientation." 52.5% who reported ever use of contraception were juniors or seniors, which indicated little difference by level of education and ever use. Family planning ever use due to health reasons was reported by 70% of participants. These findings support the research of Manda on noncollege populations about use of condoms. College students do have favorable attitudes toward contraception and toward health. This research supports the public education campaign of the Ministry of Health to promote the practice of safe sex for health reasons and the prevention of AIDS, a widespread problem in Zambia.  相似文献

This article provides an introduction for the special issue of the Journal of Science Education and Technology focused on computational thinking (CT) from a disciplinary perspective. The special issue connects earlier research on what K-12 students can learn and be able to do using CT with the CT skills and habits of mind needed to productively participate in professional CT-integrated STEM fields. In this context, the phrase “disciplinary perspective” simultaneously holds two meanings: it refers to and aims to make connections between established K-12 STEM subject areas (science, technology, engineering, and mathematics) and newer CT-integrated disciplines such as computational sciences. The special issue presents a framework for CT integration and includes articles that illuminate what CT looks like from a disciplinary perspective, the challenges inherent in integrating CT into K-12 STEM education, and new ways of measuring CT aligned more closely with disciplinary practices. The aim of this special issue is to offer research-based and practitioner-grounded insights into recent work in CT integration and provoke new ways of thinking about CT integration from researchers, practitioners, and research-practitioner partnerships.

The effect of exposure to cigarette smoke on carboxylation of myoglobin was studied in rats. The amount of carboxymyoglobin in the body tissues of rats exposed to smoke was measured and compared with normal rats. A significant quantity of myoglobin carboxylated spontaneously due to smoke was detected in the body tissues of experimental rats. Despite an adaptive elevation of total myoglobin content, a considerable reduction in the free myoglobin was observed in all tissues made under observation. This free myoglobin depletion may be the cause for increased heart rate and respiratory rate coupled with low physical activities observed in smokers.  相似文献

Measurement of serum free (ionized) calcium (Ca++) reflects true calcium status of the body in health and disease. Present study evaluates efficacy of Ca++ over total calcium (CaT) in serum for calcium status. 52 subjects were enrolled for study. Anaerobic fasting blood sample for Ca++ measurement and autoclaved plain bulb for estimation of CaT, Total protein (TP) and Albumin was used. CaT, Corrected CaT, Ca++, Calculated Ca++ were measured and correlated. Corrected CaT and calculated Ca++ were derived from the measured parameters. Study group showed significant difference between CaT and corrected CaT (p<0.006), Ca++ and calculated Ca++ (p<0.001). Negligible correlation was observed between Ca++ and serum protein. Positive correlation was observed between CaT and calculated Ca++, TP and albumin. Findings indicate that Ca++ levels are independent of serum protein status. With scrupulous sampling, Ca++ may be a better parameter than presently used CaT for assessing calcium status in serum.  相似文献

Teachers in Alaskan rural schools were surveyed on their use of instructional technology. The surveyed teachers included the entire population of certified elementary and secondary school classroom teachers of deaf and hard of hearing students in these schools. Respondents generally were older, more experienced, elementary level female teachers who were relatively well educated. Almost half of the respondents held special education certification; about 25% had an endorsement in deaf education. Data analysis indicates that educators who use instructional technology, either in curriculum or broad agenda formats, may be older, hold an advanced degree and secondary education certification, benefit from in-service training on site, are connected to the Internet, and actively use the technology available at their schools. Most of the surveyed educators identified lack of training in the use and integration of software as a barrier to increased classroom use of technology. Based on the study findings, recommendations are made concerning the training needs of teachers in rural Alaska.  相似文献
