The current age is characterised by many as secular, and a source of such a characterisation can be found in the Nietzschean claim that thoughts about there being some ultimate reality have to be jettisoned, and human existence and the world need to be embraced as they are. That claim is renewed by some secular thinkers who insist that education has to be reconceived in ways congenial to the new age. It is argued that central to their logic is the dichotomy between the religious and the secular or the otherworldly and the earthly, and that this dichotomy is simplistic as well as problematic. As an alternative to the ‘two worlds’ view, the ‘two aspects’ view is suggested, with an interpretation of reality that the noumenon––the non‐human––has to be taken in the negative sense. Against secularising the domain of education, it is indicated that there still remains a place for education to occupy between the two poles of religiousness and secularity.  相似文献

Flash mobs are new, emerging, and evolving social phenomena that have recently been associated with youth violence in the US cities. The current study explores how youth understand flash mobs through focus groups conducted in Kansas City, Missouri (a site of violent youth flash mobs). Results indicate that youth have varying familiarity with flash mobs and define them in different ways; that youth perceive youth boredom to be the most frequent cause of problems with flash mobs; that youth connect ongoing social disorder with the violence associated with flash mobs; and that while social media are facilitators of flash mobs, flash mobs have their roots in youth activities that have been going on for generations (e.g., hanging out in groups and cruising). Results illustrate the importance of conducting formative research with youth, particularly about emergent phenomena, when developing interventions and communication campaigns aimed at reducing youth violence.  相似文献

Recent advances in droplet microfluidics have led to the fabrication of versatile vesicles with a structure that mimics the cellular membrane. These artificial cell-like vesicles including polymersomes and liposomes effectively enclose an aqueous core with well-defined size and composition from the surrounding environment to implement various biological reactions, serving as a diverse functional reactor. The advantage of realizing various biological phenomena within a compartment separated by a membrane that resembles a natural cell membrane is actively explored in the fields of synthetic biology as well as biomedical applications including drug delivery, biosensors, and bioreactors, to name a few. In this Perspective, we first summarize various methods utilized in producing these polymersomes and liposomes. Moreover, we will highlight some of the recent advances in the design of these artificial cell-like vesicles for functional bioreactors and discuss the current issues and future perspectives.  相似文献

Objective. This study examined associations among Korean immigrant mothers’ use of praise and encouragement, their acculturation, their children’s socioemotional and behavioral difficulties, and the moderating role of child gender and age. Design. One hundred and twenty Korean immigrant mothers in the United States and their preschool children participated. Maternal praise and encouragement were observed during free-play interactions. Mothers reported their acculturation level, and teachers reported on children’s difficulties. Results. Mothers used process praise most frequently. Higher maternal American acculturation was associated with more use of person and other praise. Higher Korean acculturation was associated with greater use of person praise among younger children, but less use of person praise among older children. Mothers higher in American acculturation used more encouragement with older children only. Maternal encouragement was associated with fewer child difficulties. Conclusion. Korean mothers’ acculturation impacted their use of praise and encouragement, and maternal encouragement may be important for decreasing children’s difficulties.  相似文献

Both general and domain-specific search engines have adopted query suggestion techniques to help users formulate effective queries. In the specific domain of literature search (e.g., finding academic papers), the initial queries are usually based on a draft paper or abstract, rather than short lists of keywords. In this paper, we investigate phrasal-concept query suggestions for literature search. These suggestions explicitly specify important phrasal concepts related to an initial detailed query. The merits of phrasal-concept query suggestions for this domain are their readability and retrieval effectiveness: (1) phrasal concepts are natural for academic authors because of their frequent use of terminology and subject-specific phrases and (2) academic papers describe their key ideas via these subject-specific phrases, and thus phrasal concepts can be used effectively to find those papers. We propose a novel phrasal-concept query suggestion technique that generates queries by identifying key phrasal-concepts from pseudo-labeled documents and combines them with related phrases. Our proposed technique is evaluated in terms of both user preference and retrieval effectiveness. We conduct user experiments to verify a preference for our approach, in comparison to baseline query suggestion methods, and demonstrate the effectiveness of the technique with retrieval experiments.  相似文献

Gold nanoparticles (Au NPs) were directly synthesized on the surface of polyvinylsilazane (PVSZ, -[(vinyl)SiH-NH2]-) without use of extra reductive additives. The reductive Si-H functional groups on the surface of cured PVSZ acted as surface bound reducing agents to form gold metal when contacted with an aqueous Au precursor (HAuCl4) solution, leading to formation of Au NPs adhered to silicate glass surface. The Au NPs-silicate platforms were preliminarily tested to detect Rhodamine B (1 μM) by surface enhanced Raman scattering. Furthermore, gold microelectrode obtained by post-chemical plating was used as an integrated amperometric detection element in the polydimethylsilane-glass hybrid microfluidic chip.  相似文献

This study investigated professional learning taking place in a teacher-created online community. In particular, this aimed to explore how teachers at different levels of participation learn in an online community. The results showed that teachers usually began as observers, reading others' postings and using contributors' teaching resources, and moved to collaborators, posting their comments on teaching resources and discussing their problems with other teachers, and then to contributors, sharing their teaching resources with other teachers and providing information, advice, and help to other teachers. As they participated in the online community at different levels, teacher learning took place in multiple ways including learning through tryout, collaborative problem solving, and critical reconstruction. Yet, not all teachers moved toward full participation in the online community. The majority of teachers remained as observers and their lack of participation in the negotiation of meaning constrained teacher learning. For the online community to be a fertile ground for teacher learning, more emphasis needs to be placed on the collaborative construction of knowledge and the transformation of shared practice, rather than the transmission of knowledge and the dissemination of good practice.  相似文献

The authors' purpose was to examine the degree to which low achievement is related to ontogenetic factors (i.e., personal psychological traits expressed as attention and depression) or microsystemic factors (i.e., socioeconomic status, parenting, relationship with peers and teachers), using a total of 721 middle school students in South Korea. Based on the percentile rank, low-achieving students (bottom 15%; n = 323) and high-achieving students (top 15%; n = 398) were grouped, and a multigroup structural equation modeling was employed to determine which ecological factor(s) contribute to predict low achievement of middle school students. Results from multigroup structural equation modeling showed that 3 of the 6 ecological and ontological factors had significant direct or indirect effect on low achievement: socioeconomic status (direct effect), attention (direct effect), parenting (indirect effect). The findings are discussed in terms of the intertwined influences of ecological factors on low achievement, finally leading to the discussion on the limitations and future directions for research.  相似文献
