For the first time, we report on the preliminary evaluation of gold coated optical fibers (GCOFs) as three-dimensional (3D) electrodes for a membraneless glucose/O2 enzymatic biofuel cell. Two off-the-shelf 125 μm diameter GCOFs were integrated into a 3D microfluidic chip fabricated via rapid prototyping. Using soluble enzymes and a 10 mM glucose solution flowing at an average velocity of 16 mm s−1 along 3 mm long GCOFs, the maximum power density reached 30.0 ± 0.1 μW cm−2 at a current density of 160.6 ± 0.3 μA cm−2. Bundles composed of multiple GCOFs could further enhance these first results while serving as substrates for enzyme immobilization. 相似文献

Two groups of undergraduate students, matched for reading skill but differing in spelling ability, participated in three experiments with the aim of exploring the causes of differences in spelling skill in this population. In the first experiment participants were presented with a range of tasks to investigate the possibility that the poor spellers had poorer phonological abilities than the good spellers. No significant differences were observed. In Experiment 2, a lexical decision task was used. The words in the task differed in orthographic neighbourhood size (N) and frequency. Analysis of the latencies revealed effects of frequency and N, but the effect of spelling group was not significant and neither was the interaction with N. Analysis of the errors revealed that the poor spellers made significantly more errors than the good spellers. In Experiment 3 participants were asked to identify the letters in briefly presented words and non‐words. There was a significant effect of stimulus type in favour of words. Poor spellers made more errors in the task than the good spellers, although the difference was restricted to non‐words. Finally, an analysis of the errors made in spelling to dictation by the two groups was carried out. This revealed that the poor spellers were more likely than the good spellers to make errors that were not phonologically plausible and that differed markedly from the target. Overall, the results are interpreted in terms of a partial orthographic representations explanation of poor spelling in good readers. 相似文献

This paper reports two studies into the understanding of the concept of potential difference in the current-potential difference-resistance context among 8th-12th graders (Study 1), and the efficiency of a learning device derived from Social Judgment Theory (Study 2). These two studies showed that: (a) when asked to infer potential difference from resistance and current information, most participants only relied on current and ignored or greatly underestimated the importance of resistance information; (b) exposure to an electricity course did not much alter the way participants infer potential difference from resistance and current information; (c) a simple learning device considerably improved the way participants infer potential difference from resistance and current information; and (d) this observed improvement promised to be durable, at least in the short term. 相似文献

On All Saints Day 2009 a monument for body donors was unveiled by the Department of Anatomy, at the Radboud University Nijmegen Medical Centre (RUNMC). Although body donation to medical science contributes substantially to the quality of medical education, the ceremony was only the first time that the RUNMC publicly reciprocated the anatomical gift. By means of the monument the department of Anatomy endeavors to express gratitude for the gift of body donors and raise awareness among students to value the gift and treat donor bodies with the proper respect. Furthermore, the large attendance of bereaved at the unveiling ceremony, revealed another equally important meaning of the monument, which is the significance of the monument to the donor kin. The wish of a body donor has large implications for the way bereaved can take leave of the donor; there is limited time to bade the deceased farewell, the body will not be available for a funeral, and the donor kin stay behind empty handed without even a grave or ashes. Therefore the monument can be meaningful by facilitating the bereaved with a place of commemoration. The design of the monument anticipates on these multiple meanings and symbolisms by placing an old marble dissection table in the shape of an altar and fixing a bronze sculpture of a phoenix as symbol of imperishableness.

This study extends research on the relationship between hedonic and eudaimonic entertainment and its potential for recovery experiences and aspects of well-being (e.g., Rieger, Reinecke, Frischlich, & Bente, 2014). With the broad notion of what hedonic and eudaimonic media can entail, this research focused on unique affective experiences—namely, positive affect—and an expanded concept of meaningful affect (including elevation and gratitude). An online experiment with 148 full-time employees in the United States was conducted to investigate the unique role of positive and meaningful affect eliciting YouTube videos (compared to neutral control video) on recovery experiences and vitality and work satisfaction in the work context. A path model suggests that meaningful videos predicted mastery recovery experiences, whereas positive affect predicted psychological detachment and relaxation experiences. In addition, mastery recovery experiences predicted vitality, whereas relaxation experiences predicted satisfaction with work, indicating a unique potential of the consumption of meaningful and positive affect inducing YouTube videos at work for workplace well-being. 相似文献

In the context of Indigenous languages, archival science in Australia continues to move from a theoretical framework of considering record subjects as third parties to a ‘participants model’. In a participants model framework record subjects are considered co-creators and custodians of the intellectual property of the record. However, the shift from theory to practice is still an under-described challenge currently facing archival professionals. This article reports on an experience of applying guidelines developed by First Languages Australia (FLA) and National and State Libraries of Australasia (NSLA) aimed at enhancing the rights of Indigenous Australians over records that contain Indigenous language material. A team of researchers from the State Library of New South Wales (SLNSW) Indigenous Services branch and Western Sydney University engaged with four Indigenous language groups to evaluate records containing Indigenous language material held at the SLNSW. On viewing the archival records of Indigenous language material members of community groups expressed a diversity of opinions and suggestions. This feedback was grouped by the authors into the following themes: painful remembrance of the provenance of the archival record, evaluations of the value of the documents, custodianship and use of the language material, and access to the SLNSW records. The authors found that participants in the study substantially shaped the process of implementing the protocols. 相似文献

To explore the importance of text cohesion, we conducted two experiments. We measured online (reading times) and offline (comprehension accuracy) processes for texts that were high and low cohesion. In study one (n?=?60), we manipulated referential cohesion using noun repetition (high cohesion) and synonymy (low cohesion). Students showed enhanced comprehension accuracy and faster comprehension responses for text that were high in referential cohesion. In study two (n?=?52), we examined connective text designs (‘because’, ‘and’ and ‘no connective’). Students demonstrated enhanced reading times for text using a ‘because’ connective. Additionally, we examined the individual differences (reading ability, science self-concept and self-esteem) as predictors of achievement with science comprehension tasks. Across both experiments reading ability predicted comprehension with both high (noun-repetition text and ‘and’ text) and low cohesion text (synonym text and ‘no connective’ text). These findings highlight the importance of good reading abilities and text cohesion for promoting science comprehension and learning. 相似文献

More and more universities are thinking about the application of the concept of sustainable development to the education of engineers. In France, this movement generally results from isolated initiatives taken by committed individuals. In an attempt to make up lost ground, the Association pour les Pratiques du Developpement Durable has set up a working group, concerning the French engineering schools and universities which are preparing the way for the introduction of sustainable development into their teaching programmes, to pool their experience and optimize learning effects by identifying a number of principles and methods which should, in time, facilitate the spread of best practices among the members of the group and other educational establishments. 相似文献
