Counselor educators maintain a responsibility for providing site supervisors with professional development opportunities (Council for Accreditation of Counseling and Related Educational Programs. 2009 ). The goal of this study was to evaluate a model for providing preparation to site supervisors. Significant differences were observed from pretest to posttest on the Supervisory Self‐Efficacy Scale (Johnson & Stewart, 2008 ).  相似文献   

Microfluidic impedance cytometry of tumour cells in blood     

Daniel Spencer  Veronica Hollis  Hywel Morgan 《Biomicrofluidics》2014,8(6)

The dielectric properties of tumour cells are known to differ from normal blood cells, and this difference can be exploited for label-free separation of cells. Conventional measurement techniques are slow and cannot identify rare circulating tumour cells (CTCs) in a realistic timeframe. We use high throughput single cell microfluidic impedance cytometry to measure the dielectric properties of the MCF7 tumour cell line (representative of CTCs), both as pure populations and mixed with whole blood. The data show that the MCF7 cells have a large membrane capacitance and size, enabling clear discrimination from all other leukocytes. Impedance analysis is used to follow changes in cell viability when cells are kept in suspension, a process which can be understood from modelling time-dependent changes in the dielectric properties (predominantly membrane conductivity) of the cells. Impedance cytometry is used to enumerate low numbers of MCF7 cells spiked into whole blood. Chemical lysis is commonly used to remove the abundant erythrocytes, and it is shown that this process does not alter the MCF7 cell count or change their dielectric properties. Combining impedance cytometry with magnetic bead based antibody enrichment enables MCF7 cells to be detected down to 100 MCF7 cells in 1 ml whole blood, a log 3.5 enrichment and a mean recovery of 92%. Microfluidic impedance cytometry could be easily integrated within complex cell separation systems for identification and enumeration of specific cell types, providing a fast in-line single cell characterisation method.  相似文献   

Children's Conceptions About the Origin of Species: A Study of Italian Children's Conceptions With and Without Instruction     

Anna Emilia Berti  Laura Toneatti  Veronica Rosati 《学习科学杂志》2013,22(4):506-538

Investigations of people's understanding of the evolution of species have focused mainly on secondary school and university students. Very few investigations have taken into consideration younger students, and none have related children's ideas about the origin of species to formal instruction on this topic. To help fill this gap, the present study examines the effect of this instruction in elementary school children by comparing Italian second graders (n = 21; age = 7 years, 1 month, to 8 years, 7 months) with third graders (n = 18; age = 8 years, 1 month, to 9 years, 4 months) who had been taught about “the earth before humans” for several months in keeping with the Italian National Syllabus for this grade level. Semistructured interviews were used to examine children's thoughts about speciation. The majority of second graders used a creationist framework, whereas most third graders used a mixed framework (referring to both creation and evolution) or an evolutionary framework. However, children did not know about the mechanism of evolution and considered it to be the result of the passage of time, the use and disuse of body parts, or the need to adapt to a changing environment, as suggested by their teacher and textbooks.  相似文献

Narratives of agency: the experiences of Braille literacy practitioners in the Kha Ri Gude South African Mass Literacy Campaign     

Veronica I. McKay 《International Journal of Inclusive Education》2013,17(4):435-456

In this article, we locate the Kha Ri Gude South African Mass Literacy Campaign within the context of the problem of illiteracy and exclusion in South Africa, while concentrating on various post-apartheid initiatives designed to give visually challenged adults the opportunity to become literate. We shall provide a detailed account of focus group sessions organised in 2012; the aim of these sessions was to explore the experiences of blind literacy practitioners who were charged with the supervision and coordination of Braille literacy classes for blind, illiterate adults. We suggest that the way the practitioners expressed what being involved in the Campaign meant for them for an extended period (three years or more) gives us a glimpse of how, through their roles as literacy organisers, they were able to engender agency among blind adult literacy learners and themselves.  相似文献

Diversifying Science: Underrepresented Student Experiences in Structured Research Programs   总被引：1，自引：0，他引：1  

Sylvia Hurtado  Nolan L. Cabrera  Monica H. Lin  Lucy Arellano  Lorelle L. Espinosa 《Research in higher education》2009,50(2):189-214

Targeting four institutions with structured science research programs for undergraduates, this study focuses on how underrepresented students experience science. Several key themes emerged from focus group discussions: learning to become research scientists, experiences with the culture of science, and views on racial and social stigma. Participants spoke of essential factors for becoming a scientist, but their experiences also raised complex issues about the role of race and social stigma in scientific training. Students experienced the collaborative and empowering culture of science, exhibited strong science identities and high self-efficacy, while developing directed career goals as a result of “doing science” in these programs.  相似文献   

Does Educational Preparation Match Professional Practice: The Case of Higher Education Policy Analysts     

Eduardo C. Arellano  Mario C. Martinez 《Innovative Higher Education》2009,34(2):105-116

This study compares the extent to which higher education policy analysts and master’s and doctoral faculty of higher education and public affairs programs match on a set of competencies thought to be important to higher education policy analysis. Analysts matched master’s faculty in three competencies while analysts and doctoral faculty matched in five competencies. The findings suggest possible reasons why analysts and graduate faculty agree or differ on various competencies. Also, the findings raise important questions regarding the preparation of higher education policy analysts and the graduate programs that educate them. This study is an addition to the body of competency literature. Eduardo C. Arellano  obtained a B.A. in Political Science and an M.P.A from the University of Texas at El Paso, and he holds the Ph.D. in Educational Administration from New Mexico State University. He is an assistant professor at New Mexico State University in the Department of Educational Management and Development. His special interests are interactional diversity, competency, and US–Mexico border studies. Mario C. Martinez  has a B.A. in Electrical Engineering from New Mexico State University, an M.B.A. from the University of Texas at Austin, and a Ph.D. in Educational Policy and Leadership from Arizona State University. He is an associate professor at the University of Nevada-Las Vegas in the department of Educational Leadership. His special interests are higher education policy, governance, finance, competency modeling, and strategy.  相似文献   

The Necessity of Making Visible Concepts with Multiple Meanings in Science Education: The Use of the Gene Concept in a Biology Textbook     

Veronica S. Flodin 《Science & Education》2009,18(1):73-94

The purpose of this study is to analyze variations in how the gene concept is used and conceived in different sub-disciplines in biology. An examination of the development of subject matter and the use of the gene concept in a common college biology textbook shows that the gene concept is far from presented in a consistent way. The study describes and categorizes five different gene concepts used in the textbook; the gene as a trait, an information-structure, an actor, a regulator and a marker. These conceptual differences are not dealt with in an explicit manner. This constitutes one of the sources for confusion when learning about genes and genetics.
