无线局域网在internet中的应用

在这个“网络就是计算机”的时代,伴随着有线网络的广泛应用,以快捷高效,组网灵活为优势的无线网络技术也在飞速发展。无线局域网是计算机网络与无线通信技术相结合的产物,是只指在一个典型的无线局域网环境中,有一些进行数据发送和接收的设备,称为接入点(AP)。通常,一个AP能够在几十至上百米的范围内连接多个无线用户。在同时具有有线和无线网络的情况下,AP可以通过标准的Ethernet电缆与传统的有线网络相联,作为无线网络和有线网络的连接点。无线局域网的终端用户可通过无线网卡等访问网络。目前各种技术和运营方式层出不穷,在各种接入…

From ivory towers to online bazaars? The internet,social media and competing discourses in the newspaper industry

In line with the development of new media, newspaper companies are facing drastic changes in their competitive environment. Managing change requires both new capabilities and new ways of thinking. Organizational learning could be seen in terms of increasing shared organizational knowledge through changing social practices, which in turn consist of discourses. In this article we investigate the Internet and social-media-related discourse among newspaper journalists, in order to enhance understanding of how social reality is constituted and made sense of in this environment. We identify four types of discourse: Ivory-tower-creating and Shielding, which seem to impede learning, and Accelerating and Connecting, which encourage adaptation to learning and change within newspaper companies.     

Why do I take deviant disclosure behavior on internet platforms? An explanation based on the neutralization theory

Internet platforms increasingly rely on personal data to maintain user base and attract potential users. However, users might misrepresent their personal information in response to the requests when they expect their personal information to be used for unstated purposes. Misrepresenting of personal information (MPI), as a regular deviant behavior on online platforms, leads to data noises and service failures and needs further investigation. Drawing on the neutralization theory and online scenario survey, this study constructs a model to examine the factors of MPI. The results show that techniques of neutralization, such as denial of injury, defense of necessity, metaphor of the ledger, and avoidance of greater harm, are positively associated with users’ intention of MPI. In particular, avoidance of greater harm has a stronger effect on MPI intention than other neutralization techniques. Furthermore, we also explore the contingent role of personality traits. The results show that extraversion negatively moderates the relationships between denial of injury, avoidance of greater harm and MPI, whereas neuroticism plays a positive role in moderating the relationships between denial of injury, metaphor of the ledger, avoidance of greater harm and MPI. Moreover, post-hoc analysis results show that users do some differernces regarding justify their deviant disclosure behavior by using neutralization techniques between e-commerce platform and social networking site. Focusing on the dark side of disclosure behavior, this study enriches the current literature by applying neutralization theory and provides a new direction for academia and Internet practitioners to understand users’ deviant disclosure behavior.

How to describe and evaluate “deception” phenomena: recasting the metaphysics,ethics, and politics of ICTs in terms of magic and performance and taking a relational and narrative turn

Contemporary ICTs such as speaking machines and computer games tend to create illusions. Is this ethically problematic? Is it deception? And what kind of “reality” do we presuppose when we talk about illusion in this context? Inspired by work on similarities between ICT design and the art of magic and illusion, responding to literature on deception in robot ethics and related fields, and briefly considering the issue in the context of the history of machines, this paper discusses these questions through the lens of stage magic and illusionism, with the aim of reframing the very question of deception. It investigates if we can take a more positive or at least morally neutral view of magic, illusion, and performance, while still being able to understand and criticize the relevant phenomena, and if we can describe and evaluate these phenomena without recourse to the term “deception” at all. This leads the paper into a discussion about metaphysics and into taking a relational and narrative turn. Replying to Tognazzini, the paper identifies and analyses two metaphysical positions: a narrative and performative non-dualist position is articulated in response to what is taken to be a dualist, in particular Platonic, approach to “deception” phenomena. The latter is critically discussed and replaced by a performative and relational approach which avoids a distant “view from nowhere” metaphysics and brings us back to the phenomena and experience in the performance relation. The paper also reflects on the ethical and political implications of the two positions: for the responsibility of ICT designers and users, which are seen as co-responsible magicians or co-performers, and for the responsibility of those who influence the social structures that shape who has (more) power to deceive or to let others perform.     

Distinction between Trademark Right Cancellation and Invalidation Systems and Its Significance

Both cancellation and invalidation of the trademark right cause termination of a trademark right.Most national trade- mark laws clearly distinguish the system of trademark can- cellation from that of trademark invalidation.In the current Chinese Trademark Law,however,the concept of"trade- mark right invalidation"is absent.Instead,the term of"can- cellation"is used to refer to the above two circumstances.In fact,"cancellation"as provided for in Article 41 of the     

Employees’ trust and their knowledge sharing and integration: the mediating roles of organizational identification and organization-based self-esteem

We propose that the effect of trust on knowledge sharing (KS) and knowledge integration (KI) is mediated by organizational identification (OI) and organization-based self-esteem (OBSE). We focus on the relationship among different foci of trust and take into consideration that trust is a culturally dependent variable. We draw from a large-scale questionnaire survey with 50 Chinese companies and find support for our hypotheses in general. The study finds that employees’ trust within the organization is a multifaceted construct that includes their trust in the organization, trust in the supervisor and trust in peers. Trust with these different foci positively impact KS and KI. However, such effects are largely indirect and we find support for our expectation that OI and OBSE function as mediators. We conclude that trust in itself is a precondition but not sufficient condition for the actualization of KS and KI.     

Knowledge heterogeneity and social network analysis – Towards conceptual and measurement clarifications

This literature review highlights some Social Network Analysis (SNA) concepts applicable to the study of organizational knowledge and, more particularly, to knowledge heterogeneity. Knowledge being all at the same time decentralized and distributed, knowing up to what point knowledge can be heterogeneous or homogeneous across organizational units becomes as important as the question of knowing how to structure the organization. SNA applied to knowledge management thus seems a stimulant for future research in the fields of management.
