Dielectrophoretic differentiation of mouse ovarian surface epithelial cells, macrophages, and fibroblasts using contactless dielectrophoresis

Ovarian cancer is the leading cause of death from gynecological malignancies in women. The primary challenge is the detection of the cancer at an early stage, since this drastically increases the survival rate. In this study we investigated the dielectrophoretic responses of progressive stages of mouse ovarian surface epithelial (MOSE) cells, as well as mouse fibroblast and macrophage cell lines, utilizing contactless dielectrophoresis (cDEP). cDEP is a relatively new cell manipulation technique that has addressed some of the challenges of conventional dielectrophoretic methods. To evaluate our microfluidic device performance, we computationally studied the effects of altering various geometrical parameters, such as the size and arrangement of insulating structures, on dielectrophoretic and drag forces. We found that the trapping voltage of MOSE cells increases as the cells progress from a non-tumorigenic, benign cell to a tumorigenic, malignant phenotype. Additionally, all MOSE cells display unique behavior compared to fibroblasts and macrophages, representing normal and inflammatory cells found in the peritoneal fluid. Based on these findings, we predict that cDEP can be utilized for isolation of ovarian cancer cells from peritoneal fluid as an early cancer detection tool.     

Enjoying A Good Story: Why We Use Children’s Literature When Teaching Adults

Early childhood teacher educators frequently enhance their teaching by reading children’s books to their adult students. It is not unusual for faculty outside of early childhood to question devoting precious class time to read-alouds which they may consider a curious, if not frivolous, instructional strategy. Quality children’s literature can, however, enhance students’ experiences in the college classroom, contribute to their understanding of course content, promote their personal growth and self-understanding, increase their appreciation for quality children’s literature, and enhance their ability to integrate storybooks into their own teaching. Children’s books often capture a child’s point of view. They have the potential to provide historical or cultural perspectives on children and families. They also can lead to the examination of universal truths and can facilitate the discussion of sensitive or emotional issues A list of books with suggested uses is included.     

Influences of developmental contexts and gender differences on school performance of children and adolescents

This study investigated children and adolescents’ school performance over time focusing on two variables that may influence it: developmental context and gender. The sample comprised 627 participants (M_age?=?11.13, SD?=?1.8), 51% of them female, from grade one to eight, living either with family (n?=?474) or in care institutions (n?=?153). Participants answered individually the Teste de Desempenho Escolar (School Performance Test) and the Structured PRONEX Interview. Findings indicated a main effect of time on school performance (i.e., writing, reading and arithmetic). Furthermore this main effect was further qualified by a time and developmental context interaction and by a time and gender interaction. Interactions revealed that the participants from care institutions attained more significant increases in writing and reading than participants living within a family context; and that girls attained more significant increases in writing than boys. Therefore, school performance progress appears as affected by developmental contexts and gender. The findings reveal how school performance needs to be observed as a multidimensional variable, affected by individual characteristics but also by external ones.     

整形 已成现代生活的一部分?!

只要提起"动手术",很多人都会毛骨悚然。然而却有越来越多人为了"变美"而甘愿挨刀子,在整形手术从拒绝到争议再到逐渐被接受的这个过程中,我们看到了技术的进步,和人们更加开放包容的态度。但这是否就意味着我们可以无条件地接受整形?做整形手术的人数在不断增加,但没有人会对此扬起眉毛啧啧称奇。去年英国"治疗"("治疗"一词似乎不太合适,但不管了)了50,122名整形人士,而其中90%是女性,同样也     

Inequality in Preschool Quality? Community-Level Disparities in Access to High-Quality Learning Environments

In recent years, unequal access to high-quality preschool has emerged as a growing public policy concern. Because of data limitations, it is notoriously difficult to measure disparities in access to early learning opportunities across communities and particularly challenging to quantify gaps in access to high-quality programs. Research Findings: Using unique data from Georgia’s universal prekindergarten program, this study provides empirical evidence of the relationship between community characteristics and the availability of high-quality preschool opportunities. We show that in Georgia, a national leader with respect to preschool access as well as quality, there are still meaningful differences in quality across communities. Low-income and high-minority communities offer state preschool classrooms that are rated significantly lower on a widely used and validated measure of classroom process quality. Practice or Policy: This process quality gap is troubling given the positive relationship between our process quality measure and children’s learning. Note that we do not see similar gaps in structural measures of quality, which are the aspects of quality more often regulated but are also weaker, inconsistent predictors of children’s learning. Implications for policy are discussed.     

Child Readers and the Worlds of the Picture Book

Children as readers of picture books and the ways they respond to, and make meaning from, such texts are the focus of this article, which reports on a small-scale study undertaken in Norway and Wales, UK. The theoretical framing of the research draws on concepts of the multimodal ensemble in picture books and of the reading event as part of a social practice. The research design was developed from the team’s analysis of two texts, Pappa by Svein Nyhus (1998) and What does Daddy Do? by Rachel Bright (2009). Twenty-four children, who were 7 and 8 years old, took part in the study. This was built around two reading events for each book, staged as an immediate response and as a guided response. The data subsequently collected were analysed according to three overarching organisational principles, as book world, real world and play world. For both Daddy and Pappa, the first reading event showed the children’s responses were mainly directed towards exploring the book world. On the second reading event, references to the real world predominated for Daddy, while for Pappa the book world was again dominant. Across both reading events and for both books, the playworld revealed those occasions when the children expanded the meaning of the story, demonstrating an inventive ability to play with the text. Overall, the children’s responses moved fluidly across the three worlds, showing them to be energetically making connections between the reading, their experience of books and their own lives.     

What do second-order judgments tell us about low-performing students’ metacognitive awareness?

According to the unskilled and unaware effect (Kruger and Dunning 1999), low-performing students tend to overestimate their performance. Differentiating the assessment of metacognitive judgments into performance judgments (PJs) and second-order judgments (SOJs), PJs of low-performing students tend to be inflated, while their SOJs are usually lower than those of high-performing students (Händel and Fritzsche 2016; Miller and Geraci 2011). This suggests some level of awareness. The present study investigated whether low-performers’ lower SOJs actually indicate metacognitive awareness. We studied SOJs after adequate and inadequate PJs, and investigated whether low-performers’ lower SOJs are made by default or whether their lower SOJs differ in a similar magnitude compared to those of high-performers (indicating metacognitive awareness). We address this issue by disentangling student and item effects via generalized linear mixed models. Reanalyzing the data of Händel and Fritzsche (2016) from N?=?116 students, we found that SOJs depended on the students who provided the SOJ and on the items on which the SOJ was made. Overall, SOJs depended on the PJs and on the interaction of performance and PJs, but not on the performance itself. Separate analyses for students of different performance levels revealed that low-performing students showed less awareness, indicated by a non-significant interaction effect of performance and PJs. Thus, it takes mixed models to tell the whole story of low-performing students’ lower SOJs.     

From activity to transdisciplinarity and back again – preschool teachers’ reasoning about pedagogical goals

This study presents an analysis of preschool teachers’ reasoning about pedagogical goals. Of specific interest is how teachers in a Swedish and a Finnish context describe goals for children’s learning and how they describe them implementing these goals into their practice. The research question is thus: How are pedagogical goals perceived and enacted, in the thematic-oriented and play-based pedagogical practice of preschool? In-depth interviews were conducted with six preschool teachers, of which three expressed learning goals guiding their pedagogical work. The Variation Theory of learning is the guiding principle throughout the analysis, and reveals indirect and direct objects of learning and content for learning described by the three teachers. A deeper analysis of the features of these provides a comprehensive picture of pedagogical goals that are intertwined and move between activity goals, working goals and transdisciplinary goals. These results contribute to our understanding of the characteristics of preschool pedagogy and the complex pedagogical practice preschool entails.     

Citing as a sourcing practice: students’ citing self-selected online sources in their essays (Las citas como práctica del uso de las fuentes: las citas de fuentes en línea seleccionados por los estudiantes en sus trabajos)

ABSTRACT

This study examined upper secondary school students’ citations of self-selected online sources in their essays. Students (n = 140) conducted online inquiry about either effects of social media on people’s quality of life (SM) or allowance of genetic manipulation of organisms (GMO). Students, working either individually or in pairs, explored online sources with the help of a graphic organizer, after which they composed their essays. To capture the quality of citations identified in the essays, they were evaluated in terms of accuracy and richness of source features. Further, regression analysis was used to examine the effect of topic, grade level and work mode on the number and quality of citations. Results showed that students seldom cited sources in their essays, and when they did, citations were mostly accurate but less often rich in source features. When writing about SM, students most frequently cited media sources, while sources with ideological, political or religious motives were frequently cited in GMO essays. Students’ grades and work modes predicted the number of citations and number of accurate citations.
