In this treatise, three scholars join together to present what they believe to be voids and needs for the field of human performance technology (HPT). They present arguments that support the idea that HPT is an intellectual endeavor. They proceed to present a set of propositions that raise questions about trends and issues that they believe are challenges to HPT's future as a viable field of study. They conclude by presenting a set of recommendations and action plans to form a Scholar's Guild as a means to preserve, guide, and grow the field of HPT. 相似文献

Today's world of continuous change thrives on creative individuals. Anecdotal reports suggest that creative performance benefits from unconscious processes. Empirical research on the role of the unconscious in creativity, though, is inconsistent and thus far has focused mainly on one aspect of the creative process - idea generation. This is the first study to assess the role of the unconscious mind for both idea generation and idea selection. Participants generated creative ideas immediately, after conscious thought, or after a period of distraction during which unconscious thought was hypothesized to take place. After having listed their ideas, participants selected their most creative idea. Performance in idea generation was similar between conscious and unconscious thought; however, individuals who had unconsciously thought about ideas were better in selecting their most creative idea. These findings shed more light on the role of unconscious processes in creativity, and provide a means to enhance creative performance. 相似文献

Building quality work-based learning opportunities for student teachers is a challenge for schools in school-university partnerships. This study focused on the guidance of student teachers by means of a mentoring approach aimed at sharing practical knowledge, with student teachers’ learning needs as an emphasis. The approach was built on collaborative lesson planning, enactment, and evaluation.The study followed three triads (student teacher, mentor, school-based teacher educator) and examined participants’ appreciation of the effectiveness of the approach and their perception of relevant conditions. The approach was considered effective: deeper conversations appeared and new issues emerged earlier than in regular mentoring conversations. 相似文献

Open innovation is often facilitated by strong intellectual property rights (IPRs), but it may also function, and even be boosted, when firms deliberately waive some of their IPRs. Extant literature has pointed out the potential benefits of such behavior, but falls short of explaining what triggers firms to practice it in the first place and to maintain or extend it. Since the waiving of IPRs runs counter to common views on strategy and competition and to engrained practices, this is a non-trivial question. To address it, we conduct an empirical study in a segment of the computer component industry which traditionally has taken a rather proprietary stance. With the advent of the open source operating system Linux, firms increasingly waived their IPRs on software drivers. We trace and analyze this process using both qualitative and quantitative methods. Our results indicate that component makers went through a learning process, which led some to realize how selectively waiving IPRs may be beneficial for their business. We uncover customer demand pull as the initial trigger and observe how a positive feedback loop sets in subsequently, leading to a further increase in the use of selective revealing. Overall, we find that openness develops into a new dimension of competition. We discuss the implication of our findings for research on open innovation and highlight how they impact managers in practice. 相似文献

This article applies a network metaphor to an examination of the mediated public sphere. The analysis focuses on the deliberative spaces afforded by traditional and alternative media technologies, concluding that participatory digital technologies best support interactive and adaptable networks for deliberation. These networks sustain enclave and shared nodes where multiple publics can engage in deliberation within and across public boundaries. This argument informs decisions regarding broadband policy by focusing attention on values of openness, access, and freedom. 相似文献

This article focuses on the early history of X-rays. It argues that, during the first years after their discovery in 1895 by German physicist Wilhelm Conrad Röntgen, they were regarded as a technological attraction and a visual medium. While their application in medical practice was not yet fully established, the possibility of seeing into the realm of the invisible encouraged pioneers of this technology to actively exploit their visual powers. By using a media-history framework, and relying on primary and secondary sources in English, German, French, and Italian, the article takes into account three aspects of the rays' early display: its character of technological attraction; its association with photography; and its connection to beliefs in the supernatural and the occult. 相似文献
