    ^{*}Now at the Physics Dept., Washington, University, St. Louis, Missouri. 1^{1}S. P. S. Porto And D. L. Wood, J. Opt. Soc. Am, 52, 251, 1962.Author Institution: Bell Telephone Laboratories Incorporated“The ruby laser has been used successfully by Porto and Wood as a source of Raman effect.1effect.^{1} The main difficulty in their original experiments wag the large number of flashes necessary to obtain the effect even for CCl4CCl_{4} and C8H4C_{8}H_{4}. Recent improvements in our instrumentation, the most important of which is a more powerful later, has mode it possible to obtain tile Raman effect of 992cm1992 cm^{-1} vibration if benzene in one laser burst. Details of the instrumentation will be discussed well as the possibility of using the gas lasers as source for the Raman effect.

    Before church ministry practitioners can fully implement ministries to meet the needs of those with disabilities and their families, it is important for them to have a basic understanding of special education. This article provides information to help readers understand foundational concepts and vocabulary related to disabilities in order to allow them to understand those that are, or could be, part of their congregation. The article concludes with ideas for churches to consider in developing ministries that serve those with disabilities and their families. </jats:p

    Christian University Teacher Education Graduates and Perceptions of Parent Collaboration: An Exploratory Study

    No full text
    Effective collaboration between families and schools is an important factor when developing high quality education programs. When schools and families work together, children, families, schools, and communities all benefit. Using an online survey of students who completed teacher certification programs at two Christian universities, this study seeks to understand the way that completers from two teacher preparation programs, both at Christian universities, interact with parents and encourage collaboration and involvement. The research findings and implications for future research are discussed

    The ‘insider/outsider’ dilemma of ethnography: Working with young children and their families in cross-cultural contexts

    No full text
    In this article we unravel the difficulty of being researchers in the homes and classrooms of children and their families whose origins are, for one of us, very different and, for the other, very similar to our own. We first situate our work within theories of early socialization and literacy teaching which underpin our understanding of how young children in cross-cultural contexts learn. We then turn to the question of working with the families and teachers of these children which poses dilemmas not explained by the theories presented. We illustrate these through a series of vignettes typifying both the ‘Outsider’ and the ‘Insider’ role. The stories highlight paradigmatic moments of complexity, clashes or collusion which we unpick in terms of their generalizability for others working in the field. Finally, we extend theories of dialogue in our search for a methodology for collaborative work in future cross-cultural ethnographic studies

    This study investigated the correlation between psychological types, gender and science achievement. The researcher obtained the end-of-semester grades in science from the subjects7 teachers whom and administered the Myers-Briggs Type Indicator. The Selection Ratio Type Table (SRTT) and calculated values of Chi-square or fisher's exact probability analyzed the data. The Myers- Briggs Type Indicator concluded that there is no relationship between the level of science achievement and psychological type for high achieving and low achieving science students. However, it may be concluded that there is a relationship between science achievement and psychological preference for high achieving and low achieving students
