Establishing Cross-Cultural Measurement Equivalence of Scales Associated with Face-Negotiation Theory: A Critical Issue in Cross-Cultural Comparisons

To extend face-negotiation theory (FNT) to romantic relationship contexts, we examined the patterns of responses to six survey instruments among five countries. We intend this initial paper to serve as a tutorial of testing measurement invariance—specifically by elaborating on: (a) how to establish measurement equivalence and (b) how to test measurement invariance using multigroup Confirmatory Factor Analysis. The results highlight the importance of establishing equivalency and routinely testing invariance in cross- and intercultural research. This is especially important given the often-extreme equivalency challenges faced when collecting data in non-Western cultures using scales developed in Western countries.  相似文献   

Cascaded spiral microfluidic device for deterministic and high purity continuous separation of circulating tumor cells     

Tae Hyun Kim  Hyeun Joong Yoon  Philip Stella  Sunitha Nagrath 《Biomicrofluidics》2014,8(6)

Inertial microfluidics is an emerging class of technologies developed to separate circulating tumor cells (CTCs). However, defining design parameters and flow conditions for optimal operation remains nondeterministic due to incomplete understanding of the mechanics, which has led to challenges in designing efficient systems. Here, we perform a parametric study of the inertial focusing effects observed in low aspect ratio curvilinear microchannels and utilize the results to demonstrate the isolation of CTCs with high purity. First, we systematically vary parameters including the channel height, width, and radius of curvature over a wide range of flow velocities to analyze its effect on size dependent differential focusing and migration behaviors of binary (10 μm and 20 μm) particles. Second, we use these results to identify optimal flow regimes to achieve maximum separation in various channel configurations and establish design guidelines to readily provide information for developing spiral channels tailored to potentially arbitrary flow conditions that yield a desired equilibrium position for optimal size based CTC separation. Finally, we describe a fully integrated, sheath-less cascaded spiral microfluidic device to continuously isolate CTCs. Human breast cancer epithelial cells were successfully extracted from leukocytes, achieving 86.76% recovery, 97.91% depletion rate, and sustaining high viability upon collection to demonstrate the versatility of the device. Importantly, this device was designed without the cumbersome trail-and-error optimization process that has hindered the development of designing such inertial microfluidic systems.  相似文献   

The Undecidable Grounds of Scientific Expertise: Science Education and the Limits of Intellectual Independence     

Stella Gaon  & Stephen P. Norris 《Journal of Philosophy of Education》2001,35(2):187-201

Motivated by the work of Hardwig (1985, 1991) on epistemic dependence and trust in expertise, we enquire into the nature and extent of the critical assessment that non-scientists can make—and that they should be taught to make—with regard to science. Our thesis is that critical assessment of science is possible for non-experts because at the basis of science is a set of norms, beliefs and values that are contestable by non-scientists. These norms, beliefs and values are of critical importance to science education and valuable to explore from a pedagogical perspective.  相似文献   

Plowden's concern for standards     

Stella Duncan 《Education 3-13》2013,41(1):30-33

The Action on Principled Pedagogy and Learning Evaluation (APPLE) project is a cross cultural study of teaching in primary/elementary schools in England and North Carolina. The study is focused on variance in teaching, how teaching differs from the best, or most effective, that it might be, and on the relationship between professional knowledge for teaching and teachers' roles and actions. The major products of this study were: (a) a set of 16 dimensions of teaching and a model for analysis of the degree to which each dimension is an asset or barrier to learning in any given instruction and (b) a new typology of teaching, based on variance from the best that could be rather than in comparison to others. In this article we describe, briefly, the APPLE project, present the dimensions and the new typology and discuss their implications for the professionalisation of teaching. In particular, the finding that even amongst the best teachers, the ability to articulate practice in a clear, technical language is rare, is, it is argued, a major barrier to the definition of teaching as a professional activity.  相似文献

Profiles of choice: Parents’ patterns of priority in child care decision-making     

Jinseok Kim  Maryah Stella Fram 《Early childhood research quarterly》2009

Responding adequately to parental priorities for child care is important for shaping children’s early experiences and development, and for facilitating parenting at the nexus of work and caregiving roles. Although much research on child care choice has relied on variable-centered approaches that treat parental priorities as distinct and isolated, this article aims to understand parents’ care choices from a person-centered, holistic perspective. Using data from the National Household Education Survey of Early Childhood Program Participation of 2005 (n = 4570), we conduct latent class and multinomial logistic regression analyses, identifying four empirically and substantively distinctive classes of parents based on their scores on seven indicators of child care priority. Class 1 parents (35%) rank all seven indicators as very important. Class 2 parents (18%) prioritize practicality factors. Class 3 parents (9%) do not, on average, rank any of the indicators as highly important. Class 4 parents (37%) emphasize learning and quality-focused factors. Class membership is associated with child’s age, race/ethnicity, and parent respondent’s gender, age, employment status, and socio-economic status. After controlling for socio-demographic factors, parents in the learning-focused class are more likely to choose center-based cares whereas practicality-focused parents prefer home-based relative or non-relative care arrangements.  相似文献

Assessment of the Reading Skill Improvement in the Computer-Assisted Teaching of a Foreign Language     

Stella Tzortzidou  George Hassapis 《Education and Information Technologies》2001,6(3):177-191

This article reports the findings of a case study on the influence that the computer-assisted teaching of a foreign language has on the reading skill of elementary school pupils. In fact, it has been investigated the degree to which abilities inferred from the reading process are improved by delivering a typical introductory course of the French language to a Greek speaking target group, based on the use of the generic functions that most of the computer-assisted instructional tools provide. The study was focused on the abilities of perception, information retrieval and concentration and was conducted over a period of three years. It was based on the design and execution of pupil assessment tests on a control and an experimental group per year. At each year, the control group was taught the subject in the traditional textbook-based approach and the experimental group by a computer-assisted approach. The presentation of the textbook teaching material was enhanced with features that only the use of the generic functions of a computer-assisted teaching could offer. An extensive statistical evaluation of the results has disclosed that the use of the computer had definitely a positive influence on the abilities of perception and information retrieval.  相似文献   

Labor Market Returns for Graduates of Hispanic-Serving Institutions     

Toby J. Park  Stella M. Flores  Christopher J. RyanJr. 《Research in higher education》2018,59(1):29-53

Latinos have become the largest minority group in American postsecondary education, a majority of whom attend two- or four-year Hispanic-Serving Institutions (HSIs). However, little is known about labor market outcomes as result of attending these institutions. Using a unique student-level administrative database in Texas, and accounting for college selectivity, we examine whether attending an HSI influences labor market outcomes ten years after high school graduation for Latino students in Texas. We find no difference in the earnings of Hispanic graduates from HSIs and non-HSIs. This analysis represents one of the first to examine the labor market outcomes for Latino students in this sector of education accounting for critical factors that include a student’s high school and community context.  相似文献
