针对涉虚拟财产犯罪行为的规制,学界和司法实践中存在数据犯罪说、财产犯罪说、区别保护说三种观点。各种观点之间立场错位,并未形成有效交锋。刑法在规制涉虚拟财产犯罪行为时,需要结合虚拟财产的数据特性对其属性进行准确认定。虚拟财产的无形性和共享性决定了对虚拟财产的管理和转移要在占有概念规范化的基础上进行解释。虚拟财产的动态性决定了其价值只有在动态利用中才能得以彰显。根据虚拟财产的不同利用方式和利用空间,可以对其属性作出准确认定,构建"无财产性-弱财产性-强财产性"三级涉虚拟财产犯罪行为规制架构。 相似文献

现在的远程教育还未能充分地利用现有通讯技术，且对这些技术的利用也还存在许多困难，使其与传统课堂的交互程度相比仍有很大的差距。同时，目前网络技术的应用，虽使远程教育在一定程度上实现了教育资源的共享，但远不能满足个人自主化学习的需要，其中一个主要的原因是通过网络实现的共享程度仍很低，很多教育手段仍无法通过现有的传媒方式实现资源的共享。要使现代远程教育得到进一步发展，人们必需在上述两个问题上所有突破。 相似文献

The aim of this study is to investigate what is reciprocal understanding in virtual web-based interaction and what does it consist of. The context of this study was an international web-based pre-service teacher education (N=116) course. The study is based on an idea of shared cognition and reciprocal understanding, in particular. It is assumed that reciprocity is an essential component not only of social interaction, but also of successful virtual interaction. Since many kinds of virtual interaction, such as e-learning, web-based courses, and virtual universities are rapidly getting more common in education, there is a need to analyse the issue of reciprocal understanding in web-based learning in order to develop more profound pedagogical models. The results widely show that during this particular web-based course there was reciprocal discussion between the participants. Participants had mutual negotiations and they discussed about issues from a variety of different viewpoints. Seven different ideas were found for the mechanisms of reciprocal understanding. It is concluded that this information is useful for developing a new pedagogical model for web-based learning and enhancing the quality of virtual interaction. 相似文献

Understanding tissue architecture and the morphological characteristics of cells is a central prerequisite to comprehending the basis of physiological tissue function in healthy individuals and relating this to disease states. Traditionally, medical curricula include courses where students examine glass slides of cytological or tissue samples under a light microscope. However, it is challenging to implement group and peer group learning in these courses and to give students sufficient time to study specimens. An increasing number of medical schools have thus started to implement digital slide viewers, so‐called virtual microscopes, in histology and histopathology. These websites are mostly based on standard commercial software and offer limited adaptation to the special needs of first‐year students. An e‐learning platform has therefore been developed for use in cytology and histology courses. This virtual microscopy tool is coupled to a central database in which students can label and store the positions of individual structures for later repetition. As learning in pairs and peer groups has been shown to provide a high learning outcome, identified structures can be shared and discussed with students' peers or faculty via a built‐in communication module. This website has the possibility of opening an arbitrary number of frames which all can actively be moved and changed in magnification to enable the comparison of specimens and thus encourage a more global understanding of related tissues. HistoViewer is thus suggested as an e‐learning tool combining several modern teaching concepts. © 2013 American Association of Anatomists. 相似文献

针对虚拟财产进行犯罪的行为越来越多，从而给立法和司法带来了诸多问题，学术界观点不一，在认识上也往往有很大误差。针对虚拟财产进行抢劫的行为，由于存在着虚拟抢劫犯罪行为和现实抢劫犯罪行为，因而二者的定性也应有所不同。因为二者在犯罪客体、行为客观方面、社会危害性等方面都有很大的差异，针对于此，就应该采取不同的刑罚措施． 相似文献

在java开发环境中,没有涉及共享内存这个概念,但是在某一些应用中,＂共享内存＂确实非常有用。在java语言的分布式应用系统中,存在着大量的分布式共享对象,很多时候需要查询这些对象的状态,如果采用网络通信的方式,会增加应用的额外负担;如果采用共享内存的方式,则可以直接通过共享内存查看对象的状态数据和统计数据,减少了一些不必要的麻烦。 相似文献

三维虚拟现实漫游仿真和虚拟仪器实验过程仿真是目前两种主要仿真手段,前者能够很好地模拟真实实验场景,后者则能更好地仿真实验细节。为了解决传统虚拟实验交互性弱、开发周期长等问题,提出了一种Unity3D下的构件化虚拟仪器功能实现方法。首先在Unity3D平台上开发多种标准化、可复用的虚拟仪器;然后将虚拟仪器引入虚拟现实场景中,并通过基于事件中心的观察者模式实现虚拟仪器的通信和数据流动;最后,依据构建的虚拟仪器开展典型机械工程测量实验。结果表明,与传统虚拟实验相比,该方法具有更好的真实性、交互性,同时构件化的思想缩短了开发周期。 相似文献

To gain insight in the social processes that underlie knowledge sharing in teams, this article questions which team learning
behaviors lead to the construction of a shared mental model. Additionally, it explores how the development of shared mental
models mediates the relation between team learning behaviors and team effectiveness. Analyses were performed on student-teams
engaged in a business simulation game. The measurement of shared mental models was based on cognitive mapping techniques.
The results indicate that a team learning perspective provides insight in how people share knowledge. Particularly the team
learning behaviors identified as co-construction and constructive conflict are related to the development of shared mental
models. In addition, a shared mental model of the task environment in a team leads to improved performance. This underscores
the importance of developing shared cognition in teamwork. 相似文献

Teacher Design Teams (TDTs) are professional learning communities in which teachers collaborate to (re)design educational materials. Although studies have indicated that leadership is vital for TDTs’ functioning, providing adequate leadership is challenging. Both shared and vertical leadership are needed, and how to combine them is not obvious. TDT participants and coaches might benefit from insight into what shared and vertical leadership look like in practice. In this study, we monitored two TDTs that used a stepwise method that integrates shared and vertical leadership. Findings reveal that combining shared and vertical leadership in TDTs is possible, but remains a challenging balancing act. 相似文献

The increasing amount of empirical research shows that the role of regulatory processes is critical in CSCL and collaborative learning settings. However, the current conceptual definitions and specificity of the findings vary. This is most probably because of limitations in the methods investigating regulated learning in a collaborative learning context. This study aimed to provide empirical evidence for how self- and shared regulation activities are used and whether they are useful for collaborative learning outcomes. Eighteen graduate students worked in collaborative groups for seven weeks in a CSCL course and the data of this study focuses on three one week online collaborative learning phases in the course. Temporal and sequential analysis of chat discussions and log file traces were matched to find evidence about whether the students' collaboratively planned regulatory activities became shared in practice. The results show evidence that collaborative planned regulatory activities become shared in practice. The groups that achieved good learning results used multiple regulatory processes to support their learning and also reached shared regulation. The four microlevel examples demonstrate simplified patterns of the activation of self-regulation and shared regulation. In conclusion, individual socially shared regulation plays a critical role in successful collaborative learning. 相似文献
