The purpose of this study was to identify those factors related to academic success in high‐risk students so that college educators could more precisely develop remedial programs to heighten the probability of academic success for high‐risk populations. Demographic, academic, and personality variables were analyzed for groups of successful and unsuccessful high‐risk students in order to determine which were significant predictors of academic success. An analysis of the data revealed that a greater proportion of the students in the successful group were married and female. The successful group's reading score at the time of admission was significantly higher than the unsuccessful group's. The majority of the successful group had enrolled in college to acquire job related skills; the unsuccessful group had enrolled to receive transfer credits toward a baccalaureate degree. The personality analysis indicated that the successful group scored significantly higher on self‐esteem, assertiveness, and internal locus of control. Their learning style was characterized by their desire for detailed instruction, their preference for working with inanimate objects, and reading was their preferred modality for learning. The unsuccessful group scored lower on self‐esteem and higher on control by chance. The learning style inventory revealed that they did not like detailed instruction, they preferred working with people, and listening was their preferred mode of learning. Their grade expectancy was extremely unrealistic; they predicted higher grades for themselves than did the successful group. The authors suggest strategies for utilizing these findings in the development of remedial programs for high‐risk students. 相似文献

Media convergence is happening around the world. This study looks at the current operation of a cable news station that produces 2 media products in 1 newsroom. It also explores the theoretical foundations of value creation in online news by examining how online news is selected, packaged, processed, and distributed. Observational results showed that media convergence still has a long way to go. More important, this study found several divides between the Web people and the news people, between the managers and the reporters, and between the news department and the advertising department. This article suggests that convergence would go more smoothly if stations would integrate Web producers into the newsroom; if reporters were given incentive to do extra work or if their daily work load were adjusted to give them time to file for the Web; and if the sales people better understood the value of the online product. 相似文献

In recent years, policy documents, curricula and other educational initiatives have promoted a pedagogy founded on the concept of independent learning. This is broadly defined as ‘having the belief in yourself to think through learning activities, problems or challenges, make decisions about your learning and act upon those decisions’. The central role of Assessment for Learning (AfL) in this process is often overlooked in practice. By considering the findings from a small-scale research study this article addresses the central role of the teacher/practitioner in developing effective AfL in the early years classroom (3–5 years). 相似文献

This study examined the transactional, utterance-by-utterance dependencies in the syntactic complexity of teachers’ and children's talk during small-group conversations in preschool classrooms. The sample included 39 teachers and select children in their classroom, which targeted enrollment to children experiencing documentable risk factors. Patterns of sequential dependencies demonstrated a bi-directional interdependence in teachers’ and children's complex syntactic use, whereby both teachers and children appeared sensitive to each other's use of complex syntactic forms. Teachers’ use of complex syntax increased the likelihood that children's adjacent utterance would contain complex syntax; similarly, children's use of complex or simple syntax increased the likelihood that teachers’ adjacent utterance would mirror their syntactic level. Associations were small to moderately large in strength, but varied across individual classrooms. The findings point to complex, bi-directional relationships underlying the complexity of talk within the classroom language environment. 相似文献

A versatile method to fabricate a multilayer polydimethylsiloxane (PDMS) device with micropillar arrays within the inner layer is reported. The method includes an inexpensive but repeatable approach for PDMS lamination at high compressive force to achieve high yield of pillar molding and transfer to a temporary carrier. The process also enables micropillar-containing thin films to be used as the inner layer of PDMS devices integrated with polymer membranes. A microfluidic cell culture device was demonstrated which included multiple vertically stacked flow channels and a pillar array serving as a cage for a collagen hydrogel. The functionality of the multilayer device was demonstrated by culturing collagen-embedded fibroblasts under interstitial flow through the three-dimensional scaffold. The fabrication methods described in this paper can find applications in a variety of devices, particularly for organ-on-chip applications. 相似文献

This article focuses on Radio Bilingüe, a community driven Spanish-language public radio station that serves the information and entertainment needs of one of the most disenfranchised Latino communities across local, national, and transnational borders. The author discusses its establishment as a result of the formation of CPB’s Task Force on Minorities and explains the role Radio Bilingüe plays in helping elevate minority voices in public broadcasting. This case illustrates how a Latino owned and operated radio enterprise empowers traditionally underrepresented Latino communities by providing them a space where they can be heard and represented in culturally sensitive ways. 相似文献

Birch bark is commonly found in indigenous collections in Canadian museums. It is empirically known that light can cause the cambium side of birch bark to change colour. The purpose of this research is to better assess the light sensitivities of various colours of birch barks, and the manner, degree, and rate of colour change during light exposure. Six barks with different colours were used: beige, yellow, orange, orange-brown, red, and brown. Samples were exposed to daylight through a north-facing window (window), LED light from an enclosed chamber (LED), and the Newport-Oriel microfade tester (MFT). Window and MFT samples received a total light dose of approximately 25 Mlux-hours, and LED samples, 182 Mlux-hours. Colour monitoring of the samples showed that almost all barks initially darkened and then faded. Daylight through window caused the most rapid and extensive darkening and fading. Bluewool (BW) ratings for window samples were the lowest (most light sensitive). The MFT and LED samples showed a similar degree of colour change, with the same dose, despite the difference in intensity. Ratings of MFT samples are within one BW step difference compared to LED samples. The rate and extent of initial darkening depended on the colour of the bark; the middle range orange-toned barks showed the most rapid and extensive darkening followed by fading. 相似文献
