In this paper we present a new fabrication method that combines for the first time popular SU-8 technology and PerMX dry-photoresist lamination for the manufacturing of high aspect ratio three-dimensional multi-level microfluidic networks. The potential of this approach, which further benefits from wafer-level manufacturing and accurate alignment of fluidic levels, is demonstrated by a highly integrated three-level microfluidic chip. The hereby achieved network complexity, including 24 fluidic vias and 16 crossing points of three individual microchannels on less than 13 mm(2) chip area, is unique for SU-8 based fluidic networks. We further report on excellent process compatibility between SU-8 and PerMX dry-photoresist which results in high interlayer adhesion strength. The tight pressure sealing of a fluidic channel (0.5 MPa for 1 h) is demonstrated for 150 μm narrow SU-8/PerMX bonding interfaces. 相似文献

The multidimensional concept of creativity has a much wider scope of application than disclosed by prevailing research on sporting creativity. In this area, creativity is mostly perceived, praised, and approached for its performative, in-game benefits. Pointing to the belief that creativity requires well-developed technical skills, this phenomenon is often treated as a performative end. When targeting creative match performances, the developmental and experiential benefits of creative activities may be neglected, and creativity may be reserved for the best offensive players. To nourish and nuance practical and scholastic dialogues, the purpose of this paper is to conceptualize creativity as a developmental resource in sport training activities. This is accomplished by building on and articulating [Shilling, C. (2005). Body in culture, technology and society. London: SAGE] body-sociology, [Gl?veanu, V. P. (2012). What can be done with an egg? Creativity, material objects, and the theory of affordances.

Democracy and education– an introduction to the philosophy of education. New York, NY: The Free Press.] educational philosophy. Based on these positions, creativity is treated as a dynamic quality of action that is located in the transaction between the player and the specific situation (i.e. affordances, intentions, and norms). Hence, creativity regards the exploratory and playful processes of discovering, exploiting, and originating unusual action possibilities (i.e. acting on unperceived, unexploited, and uninvented affordances). Grounded in these ideas, we argue for the stimulation of creative actions during training, which should not be forgotten when trying to nurture in-game creativity. Essentially, the developmental benefits (e.g. learning and enjoyment) of creativity could apply to all players, at all levels. Among others, creativity may enhance their situated potential (e.g. expanding the boundaries of usual actions; developing the capacity for novel actions). For instance, the exploration of unexploited affordances (i.e. actions normally avoided due to norms) entails broad experiences and may help the players discover novel actions. Moreover, creative activities may develop the players’ capacity to search for, handle, and/or create unexpected, unusual, and novel situations. This is vital for players’ development and performance. 相似文献

A right to preserve one’s culture is recognised in the United Nations human rights treaty system. Individual and collective cultural identity within government and private archives can be enabled through a participatory approach which acknowledges record subjects as record co-creators. This article analyses cultural human rights instruments found in international and domestic Australian laws as warrants for a participatory archive within the Australian context, premised on the recognition of the rights of those who are subjects of the record to add their own narratives to records held in archival institutions, and to participate as co-creators in decision-making about appraisal, access and control, thus shaping and reshaping the archive from their perspective. To this end, it proposes the use of social media to enhance cultural rights and cultural identity. Adopting the principle of rights maximisation, a participatory approach lessens the impact of the right to be forgotten on cultural rights. The article concludes that Australian archival policy makers and jurisdictions which have a human rights regime, have a clear mandate to give priority to the preservation of records of distinctive cultures, in particular those of Indigenous peoples and minorities. 相似文献

In this response, we commend Sternberg’s Active Concerned Citizenship and Ethical Leadership (ACCEL) model yet urge him to consider an ACCEL-S model that more fully incorporates society’s integrative role in giftedness. ACCEL-S builds on the highly complex and contextual view of giftedness proposed by Sternberg and transforms it into a participatory framework. Within it, the skills associated with giftedness shape but are also shaped by social context; they generate meaningful forms of collaboration as well as grow out of them. The concept of giftedness itself is transformed from a person-centric one to a distributed model in which being gifted is a relational instead of purely personal achievement. 相似文献

This article addresses the question of whether children are or are not creative by exploring the assumptions underlying each possible answer. It is argued that our position regarding children's creativity steams from larger systems of representation concerning children on the one hand, and creativity on the other. Arguments for and against the idea that children can be creative are then considered from four different perspectives: the product, process, person and press factor. On the whole, children's creativity is accounted for in terms of a particular ‘reading’ of children as active and interactive beings and of creativity as a social and cultural phenomenon. In contrast, children's lack of creative expression is linked with a passive and receptive image of the child and with theorising creativity through the lenses of the genius and of great creations. In the end, the benefits of acknowledging children's creativity are considered for child and developmental psychology, for creativity research and for educational practices. 相似文献

Media industries in the United States have consolidated significantly in the second half of the last century. One consequence of the consolidation is a restructuring of the way the industries construct and access their labor markets. As the media group integrates or even coordinates the hiring of personnel, the Internal Labor Market can be expanded to cover all or major parts of the media company. Creation of what is termed here an Extended Internal Labor Market has the potential to alter personnel practices in the group. This article tested this expectation in one specific area, the hiring of and investment in journalists, for one type of media, the daily newspaper industry. One indicant of quality hiring is the location and employment of journalists who are members of racial or ethnic minority groups. It was predicted in this article that daily newspapers that are part of an optimally configured Extended Internal Labor Market would be more likely to hire minority journalists than other newspapers. These newspapers also were expected to be more likely to value professional development of their journalists, and to provide encouragement for their journalists to engage in both internal and external training activities. The data are generally consistent with the hypotheses. The size of the company plays an important role in understanding the relationships. 相似文献
