Adults enrolled in basic education exhibit poor academic performance, often reading at elementary and middle-school levels. The current study investigated the similarities and differences of reading skills and eye movement behavior between a sample of 25 low-skilled adult readers and 25 first grade students matched on word reading skill. t tests for matched pairs found no significant differences on language comprehension, reading comprehension, or eye movement variables. Regression analyses revealed that language comprehension made greater contributions to reading comprehension for adults (verses children) in the simple view of reading model. Processing time (gaze duration) was found to account for unique variance in both passage reading comprehension and sentence comprehension efficiency after controlling for word reading and language skills for adults. For children, processing time was only a significant predictor for sentence comprehension efficiency. 相似文献

We examine the effects of Title I on school behavior, resources, and academic performance using a rich set of school finance and student-level achievement data from one large urban school district using a regression discontinuity design. We find that Title I eligibility raises Federal revenues of schools by about $460 per student. This is partially offset by decreases in revenues from state categorical aid grants, so that the net increase to schools is about $360 per student. We find no impact on overall school-level test scores, but also no impact among the subgroups of students most likely to be affected by Title I. A novel finding is that schools appear to respond to the incentives embedded in the Title I allocation process by manipulating the fraction of their students signed up for free lunch to secure more Federal funds. 相似文献

Abstract The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (≥80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003 – 1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010 – 1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout. 相似文献

A study carried out for the UK Joint Information Systems Committee examined models for the provision of access to material in institutional and subject‐based archives and in open access journals. Their relative merits were considered, addressing not only technical concerns but also how e‐print provision (by authors) can be achieved – an essential factor for an effective e‐print delivery service (for users). A ‘harvesting’ model is recommended, where the metadata of articles deposited in distributed archives are harvested, stored and enhanced by a national service. This model has major advantages over the alternatives of a national centralized service or a completely decentralized one. Options for the implementation of a service based on the harvesting model are presented. 相似文献

The current study sought to measure the influence of a one-hour library training/orientation session on college students' library use and library skill development. Data analysis revealed a statistically significant increase in student library use while there was no statistically significant increase in library skill development. Some issues, however, limited the utility of the findings. This paper also critiques the study's design with the intention of helping future researchers plan for occurrences that may limit the accuracy of their findings. 相似文献

Alternating-current (AC) electrokinetics involve the movement and behaviors of particles or cells. Many applications, including dielectrophoretic manipulations, are dependent upon charge interactions between the cell or particle and the surrounding medium. Medium concentrations are traditionally treated as spatially uniform in both theoretical models and experiments. Human red blood cells (RBCs) are observed to crenate, or shrink due to changing osmotic pressure, over 10 min experiments in non-uniform AC electric fields. Cell crenation magnitude is examined as functions of frequency from 250 kHz to 1 MHz and potential from 10 Vpp to 17.5 Vpp over a 100 μm perpendicular electrode gap. Experimental results show higher peak to peak potential and lower frequency lead to greater cell volume crenation up to a maximum volume loss of 20%. A series of experiments are conducted to elucidate the physical mechanisms behind the red blood cell crenation. Non-uniform and uniform electrode systems as well as high and low ion concentration experiments are compared and illustrate that AC electroporation, system temperature, rapid temperature changes, medium pH, electrode reactions, and convection do not account for the crenation behaviors observed. AC electroosmotic was found to be negligible at these conditions and AC electrothermal fluid flows were found to reduce RBC crenation behaviors. These cell deformations were attributed to medium hypertonicity induced by ion concentration gradients in the spatially nonuniform AC electric fields. 相似文献

Recently, the margins between gaming and feminism have become increasingly contentious (Salter & Blodgett, 2012). This article addresses a cultural moment where masculine gaming culture became aware of and began responding to feminist game scholars by analyzing GamerGate conspiracy documents and social media discussions related to the now infamous “DiGRA fishbowl.” Worries about the opacity of academic practices and a disparaging of feminist knowledge-making practices dominate these documents. By looking at these discussions and practices through the lens of conspiracy theories (Fenster, 2008; Hofstadter, 1952) and counterknowledge (Fiske, 1994) we consider the broader meaning of GamerGate's attention to academia. 相似文献
