Bandpass sorting of heterogeneous cells using a single surface acoustic wave transducer pair

Separation and sorting of biological entities (viruses, bacteria, and cells) is a critical step in any microfluidic lab-on-a-chip device. Acoustofluidics platforms have demonstrated their ability to use physical characteristics of cells to perform label-free separation. Bandpass-type sorting methods of medium-sized entities from a mixture have been presented using acoustic techniques; however, they require multiple transducers, lack support for various target populations, can be sensitive to flow variations, or have not been verified for continuous flow sorting of biological cells. To our knowledge, this paper presents the first acoustic bandpass method that overcomes all these limitations and presents an inherently reconfigurable technique with a single transducer pair for stable continuous flow sorting of blood cells. The sorting method is first demonstrated for polystyrene particles of sizes 6, 10, and 14.5 μm in diameter with measured purity and efficiency coefficients above 75 ± 6% and 85 ± 9%, respectively. The sorting strategy was further validated in the separation of red blood cells from white blood cells and 1 μm polystyrene particles with 78 ± 8% efficiency and 74 ± 6% purity, respectively, at a flow rate of at least 1 μl/min, enabling to process finger prick blood samples within minutes.  相似文献

Teachers’ resilience and well-being: a role for educational psychology     

Simon Gibbs  Andy Miller 《Teachers and Teaching》2014,20(5):609-621

The retention and resilience of teachers are subject to many influences. Children’s behaviour is often cited as a major source of stress for teachers and a challenge to their resilience. We suggest that an understanding of teachers’ attributions and efficacy beliefs may provide the foundations for work to support teachers. We outline findings from research that has examined teachers’ attributions for the causes of children’s misbehaviour, teachers’ beliefs in their efficacy as classroom managers of children’s behaviour as well as how, in principle, such beliefs may be supported and enhanced. We also relate these findings to those associated with educational and developmental outcomes for children. We conclude with some illustrative evidence of ways (involving consultation and other interventions) that applied psychologists have contributed to the professional well-being and resilience of teachers.  相似文献   

Individual differences in decision-making and confidence: capturing decision tendencies in a fictitious medical test     

Simon A. Jackson  Sabina Kleitman 《Metacognition and Learning》2014,9(1):25-49

Decision-making is a complex process that is largely studied from an experimental perspective or in specific organizational contexts. As such, no generalizable framework exists with which to study decision-making from an individual differences perspective for predictive/selection purposes. By generalising a context-specific decision model proposed by Koriat and Goldsmith (1996), the focus of this research was to therefore test a novel framework for studying individual differences in decision-making tendencies. Utilising this framework within a fictitious Medical Decision-Making Test (MDMT) yielded five novel variables that provided unique insight into individuals’ decision tendencies: Optimal, Realistic, Incompetent, Hesitant and Congruent. Metacognitive confidence and its calibration (bias and CAQ) were used as predictor variables to validate this framework. One hundred ninety-three undergraduate students completed the MDMT and three cognitive ability tests with confidence ratings, a personality questionnaire, and the Need for Closure questionnaire. All decision tendency variables demonstrated excellent internal consistency and were predicted by the metacognitive variables incrementally to the remaining variables as hypothesized. Additionally, the metacognitive indices were found to generalize across the decision-making and cognitive tests. The results imply that this novel framework and MDMT reliably capture individuals’ decision behaviour that shares a meaningful relationship with their general confidence and calibration.  相似文献   

Multiple Copies of Bestsellers in Public Libraries: How Much Is Enough?     

Michelle Gordon  Allison Haack  Rebecca Vernon  Tiffany Saulter  Debora Shaw 《Public Library Quarterly》2014,33(2):145-154

How do public libraries develop their collections of high-demand materials for the “I want it now” generation? Ten public libraries’ holdings of fiction and nonfiction bestseller titles were observed over a four-week period. The number of copies rose fairly consistently, with the five fiction titles having roughly about twice the number of copies as the five nonfiction titles. The ratio of holds to copies averaged 2.7:1 and ranged from 0.8:1 to 6.5:1. Demand for e-books was consistently higher than the number of copies available, averaging more than 4:1 across all libraries.  相似文献
