Gold coated optical fibers as three-dimensional electrodes for microfluidic enzymatic biofuel cells: Toward geometrically enhanced performance

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.     

The governance and standardisation of research information in different science systems: A comparative analysis of Germany and Italy

This paper takes a policy‐analytical perspective on the evolution of standards of research information (RI) and provides a framework for analysing processes of RI standardisation in different research systems. It focuses on the choice of policy instruments on the macro level (government) and their effects with regard to policy reactions, decisions and practices on the meso level (Higher Education institutions). Next to providing a conceptual frame for analysing and comparing—direct and indirect—RI standardisation processes, the paper presents exploratory evidence with regard to the German and Italian science systems. The empirical analysis shows that policies (indirectly) regulating the institutional processing of RI (e.g., evaluation policies) might indeed lead to the standardisation of RI in a science system. Policy reactions on the meso or organisational level, which largely shape the standardisation dynamics, depend on the strategic relevance of the policy and on available implementation support.     

Phonological skill,lexical decision and letter report performance in good and poor adult spellers

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.     

An altar in honor of the anatomical gift

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.

Key skills for science learning: the importance of text cohesion and reading ability

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.     

Watching Online Videos at Work: The Role of Positive and Meaningful Affect for Recovery Experiences and Well-Being at the Workplace

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.     

Why build a network about introduction of sustainable development into scientific education?

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.     

Building Preschool Children's Emotional Competence: A Parenting Program

Poor emotional competence has been identified as a precursor to later social, emotional, and behavioral difficulties in children. Aspects of parenting, including modeling, reactions to and coaching of children's emotions, have been associated with the development of emotional competence in children. In this paper, a parenting program with this theoretical basis is outlined and a pilot study of the program is presented. The six-session parenting program was delivered in preschool centers to 47 parents with a four or five year old child, and data were collected about parenting and children's functioning twice prior to program commencement, following program completion, and at three month follow-up. Pre and post program teacher assessments were also collected. Following the program parents reported that they were more encouraging of their children's emotional expression, used emotion-focused approaches more frequently in interactions with their children, and were less critical and dismissive of their children's emotional expression. Their children showed less emotional negativity and had significant reductions in difficult behaviors, especially those who had behavior problems prior to their parents' participation in the program. This program offers a promising approach to fostering the development of children's emotional competence and consequently enhancing social and behavioral functioning.     

Working memory in Dutch children with reading- and arithmetic-related LD

The aim of the two studies presented in this article was to examine working memory performance in Dutch children with various subtypes of learning disabilities. The performance of children with reading disabilities (RD) was compared to that of children with arithmetic disabilities (AD), children with both reading and arithmetic disabilities (RAD), and chronological age-matched controls (CA). Measures covered the phonological loop, the visuospatial sketchpad, and the central executive. In both studies, the children with RD showed no working memory deficits whatsoever. Children with AD showed a single impairment on the task tapping working memory for dynamic visual information. Children with RAD performed lower only on the digit span backward task. The failure to replicate the expected working memory deficits in children with reading-related disabilities is discussed.
