We present a straightforward and rapid surface acoustic wave (SAW) atomization-based technique for encapsulating proteins into 10 μm order particles composed of a biodegradable polymeric excipient, using bovine serum albumin (BSA) as an exemplar. Scans obtained from confocal microscopy provide qualitative proof of encapsulation and show the fluorescent conjugated protein to be distributed in a relatively uniform manner within the polymer shell. An ELISA assay of the collected particles demonstrates that the BSA survives the atomization, particle formation, and collection process with a yield of approximately 55%. The SAW atomization universally gave particles with a textured morphology, and increasing the frequency and polymer concentration generally gave smaller particles (to 3 μm average) with reduced porosity. 相似文献

Co-assessment is a type of participatory assessment in which the teacher and student jointly discuss, negotiate and assess the student’s task or performance. Although the literature on co-assessment is scarce, some authors highlight the benefits for students of participating in co-assessment in higher education, including learning, improved communication, and greater assessment literacy. This study has a double objective: on the one hand, to analyse the strengths and limitations perceived by students participating in co-assessment practices; on the other hand, to explore the strengths, weaknesses, opportunities and threats perceived by professors participating in the experience. The study was developed in 8 class groups with the participation of 470 students and 4 teachers. The qualitative analysis of the data obtained from the questionnaires and focus groups indicates that the students acknowledged several strengths, among which learning from mistakes was prominent. Students also noted some limitations, particularly the lack of adjusted scoring. Professors offered another perspective that complemented the vision of their students, noting that co-assessment presents opportunities as well as risks that may jeopardise its implementation. 相似文献

This study examined the effect of (a) high- and low-level questions and (b) reading the text before the questions asked on performance, delayed text recall, and deep text comprehension, as well as on specific text-inspection patterns. Participants were 37 undergraduate students who answered either high- or low-level questions using the software Read&Answer to read and answer questions on the computer screen. Additionally, half of the sample read first a text and then answered the questions (reading-first condition), whereas the other half answered the questions without having read the text in advance (no-reading-first condition). All participants had the text available to search for the answer. Results indicated that high-level questions facilitated deep comprehension but not immediate performance or delayed recall of text, independently of the reading condition, and that high- and low-level questions differentially affected text-inspection patterns. 相似文献

The main purposes of this research were twofold. We examined the samenesses about learning disabilities (LD) in Guatemala and Spain, two countries with the same language but cultural, political, and educational differences, first analyzing data about the prevalence of reading and spelling disabilities in Guatemala City and the Spanish region of the Canary Islands. The focus of the second study was to determine whether there are cross‐national patterns of significant differences in cognitive processes associated with reading and spelling disabilities from a developmental approach in these two cultural contexts. We found some differences in the prevalence of specific LD in reading between both countries but we did not find significant differences between Guatemalan and Spanish reading‐disabled children in cognitive processes that are involved in reading and spelling acquisition in spite of the cultural and educational differences between the two countries. 相似文献

Using the case of FC Barcelona and Catalonia, this paper examines the relationship between national identity, social institutions and political values. Through different methods of qualitative research, we present an intergenerational comparison between age cohorts to capture continuities and discontinuities in the discursive linkage between FC Barcelona and national feelings of belonging. As the context has changed, the identity construction process should have changed in conjunction with it. The results point to how the old cohort tended to use Barça, as an escape valve, intertwined with Catalan nationalism and political freedom. In contrast, the young ones reproduce the old discourse leaving aside those political values formerly attached to the idea of Barça. 相似文献
