Substantial evidence documents the superiority of breastfeeding for mothers and breastmilk for babies. Although the American Academy of Pediatrics and the U.S. Healthy People 2010 initiative promote breastfeeding, current breastfeeding rates often fall short of recommendations. This study determined factors associated with exclusive breastfeeding 2 to 4 weeks following discharge from a large, urban, academic medical center striving for Baby-Friendly designation. Results indicated that mothers who breastfed within the first hour of birth (61%) were significantly more likely to be exclusively breastfeeding 2 to 4 weeks after discharge. Incorporating care practices that include a number of the "Ten Steps to Successful Breastfeeding," as recommended by the Baby-Friendly Hospital Initiative, may increase the duration of exclusive breastfeeding after discharge. 相似文献

Apprenticeship and professional development schools (PDSs) are two models for teacher education. The mentors that are the focus for this research completed their initial teacher training through one of these models and now mentor in PDSs. The paper reports on how the way in which they were trained as student teachers influenced their role perceptions. The findings suggest that mentor teachers who were trained via the PDSs model have a broader conceptual understanding of their role perception. 相似文献

The study examines the professional development of junior-high-school teachers participating in the Israeli “Katom” (Computer
for Every Class, Student and Teacher) Program, begun in 2004. A three-circle support and training model was developed for
teachers’ professional development. The first circle applies to all teachers in the program; the second, to all teachers at
individual schools; the third to teachers of specific disciplines. The study reveals and describes the attitudes of science
teachers to the integration of laptop computers and to the accompanying professional development model. Semi-structured interviews
were conducted with eight science teachers from the four schools participating in the program. The interviews were analyzed
according to the internal relational framework taken from the information that arose from the interviews. Two factors influenced
science teachers’ professional development: (1) Introduction of laptops to the teachers and students. (2) The support and
training system. Interview analysis shows that the disciplinary training is most relevant to teachers and they are very interested
in belonging to the professional science teachers’ community. They also prefer face-to-face meetings in their school. Among
the difficulties they noted were the new learning environment, including control of student computers, computer integration
in laboratory work and technical problems. Laptop computers contributed significantly to teachers’ professional and personal
development and to a shift from teacher-centered to student-centered teaching. One-to-One laptops also changed the schools’
digital culture. The findings are important for designing concepts and models for professional development when introducing
technological innovation into the educational system. 相似文献

This paper explores the role played by habit in shaping audience behavior through an analysis of Nielsen audience data. Through the use of a structural equation model, comparisons, are made between individuals’ weekday and weekend viewing patterns to determine if similarities persist despite the structural and programmatic differences in those time periods. Results indicate that habit plays a significant role in viewing behavior. 相似文献

The aim of this study was to assess changes in body morphology, anatomical alignment and prevalence of patellofemoral pain (PFP) in young female dancers along one year of pubertal growth, and to identify the risk factors related to PFP in these young dancers. Both legs of 60 dancers were evaluated during grade 7 and again after 1-year. At each of these points in time, the dancers were interviewed concerning their background, and anthropometric measurements, lower-limb physical examinations and knee ultrasound scans were performed. Morphological parameters changed significantly from baseline to follow-up. PFP was found in 53.3% of the dancers’ knees at baseline. At follow-up, 55.4% of the asymptomatic knees at baseline developed PFP, and only 9.4% of the symptomatic knees at baseline recovered. Lower BMI was identified among dancers who developed PFP during follow-up compared with dancers with no PFP, either at baseline or at follow-up. A positive grinding and positive Patellar Inhibition Test (PIT) were found to be risk factors for PFP at follow-up. A high prevalence of young dancers suffered PFP, from injuries they sustained mostly during the 1-year of dance practice. Parameters predisposing the dancers to PFP should be identified at early stages of dance class. 相似文献

This study focuses on the working contract between the on‐site mentor and school‐based counseling interns within the specific context of the on‐site mentoring role, underlining the importance of the contract as a framework for empowering internship and mentoring. Guidelines concerning the main contents and processes needed for outlining an effective contract are presented. A study that examined expectations of mentors and interns regarding the components of the contract is presented with the aim of illustrating the creation of a data‐driven basis for contracting. Four similar broad categories were located, although differences between mentors and interns in each category appeared. Implications of the working contract for the enhancement of the mentorship relationship and for the professional growth of mentors and interns are discussed. 相似文献
