Peer-to-Peer (P2P) computing offers many attractive features, such as collaboration, self-organization, load balancing, availability, fault tolerance and anonymity. However, it also faces many serious challenges. In our previous work, we implemented a synchronous P2P collaboration platform called TOMSCOP. Based on the elementary peer group services offered by the JXTA general framework, TOMSCOP provides four types of services: synchronous message transportation, peer room administration, peer communication support and application space management. By using the four services, different kinds of shared applications for various specific purposes can be relatively easily developed and associated collaborative cyber spaces or communities can be quickly built across the JXTA virtual network overlaid on top of the existing physical networks. However, the TOMSCOP was implemented only in Windows XP OS. In this paper, we extend our previous work and present the implementation of a Multi-Platform P2P System (MPPS). The proposed system operates very smoothly in UNIX Solaris 9 OS, LINUX Suse 9.1 OS, Mac OSX, Windows XP and NetBSD.

Peer-to-peer (P2P) computing offers many attractive features, such as self-organization, load-balancing, availability, fault tolerance, and anonymity. However, it also faces some serious challenges. In this paper, we propose an Efficient Clustered Super-Peer P2P architecture (ECSP) to overcome the scalability and efficiency problems of existing unstructured P2P system. With ECSP, peers are grouped into clusters according to their topological proximity, and super-peers are selected from regular peers to act as cluster leaders and service providers. These super-peers are also connected to each other, forming a backbone overlay network operating as a distinct, yet integrated, application. To maintain the dynamically adaptive overlay network and to manage the routing on it, we propose an application level broadcasting protocol: Efa. Applying only a small amount of information about the topology of a network, Efa is as simple as flooding, a conventional method used in unstructured P2P systems. By eliminating many duplicated messages, Efa is much more efficient and scalable than flooding, and furthermore, it is completely decentralized and self-organized. Our experimental results prove that ESCP architecture, combined with the super-peer backbone protocol, can generate impressive levels of performance and scalability.

Purpose: This article presents a model that the author calls the Collaborative Enterprise (CE). It serves as a general framework for thinking about all collaborations. Distinguishing feature: The CE focuses first on the purpose of a collaboration, and it then turns to participants, resources and capabilities, and processes. It illustrates the relevance of the model with three mini-case studies. Model type: The model is developed via schematic diagrams and narrative explanation. Model components: The CE posits four generic agents that collectively leverage resources and capabilities as they engage in a structured series of processes. Model attributes: The CE illustrates combinations of self-organization and hierarchy among agent types and emphasizes key processes in a collaboration. Literature: Literature from business strategy; organizational theory; and basic systems theory, including complex adaptive systems, inform the CE. Key insights: The purpose of the CE is to create distributed value by launching initiatives in functional arenas to shape the determinants of high-level goals. Implications: Success in creating distributed value is possible but challenging.

Hopf Theorem

We show in a very general framework the a.s. convergence of the one-dimensional Kohonen algorithm–after self-organization–to its unique equilibrium when the learning rate decreases to 0 in a suitable way. The main requirement is a log-concavity assumption on the stimuli distribution which includes all the usual (truncated) probability distributions (uniform, exponential, gamma distribution with parameter ≥ 1, etc.). For the constant step algorithm, the weak convergence of the invariant distributions towards equilibrium as the step goes to 0 is established too. The main ingredients of the proof are the Poincaré-Hopf Theorem and a result of Hirsch on the convergence of cooperative dynamical systems.

Status-authority asymmetry in the workplace emerges when lower-status professionals are ascribed with higher functional authority to oversee higher-status professionals and elicit compliance from them. However, eliciting compliance from the higher-status professionals is ridden with challenges. How and when lower-status professionals with functional authority could elicit compliance from higher-status professionals? To examine this question, I conducted a 24-month ethnography of 911 emergency coordination to understand how 911 dispatchers (lower-status professionals with functional authority) were able to elicit compliance from the police officers (higher-status professionals). I identify a set of relational styles – entailing interactional practices and communication media – enacted by the 911 dispatchers. Findings suggest that as compared to the customizing and the escalating relational styles enacted via the private communication medium, the publicizing relational style (i.e., publicizing the noncompliant behavior of an officer to his immediate peers) enacted via the peer communication medium enabled the dispatchers to elicit compliance. Such peer publicizing triggered self-disciplining, as that noncompliant officers’ trustworthiness is on the line in front of the peer group. More generally, through enrolling the alters’ peers in the compliance process, the lower-status professionals with functional authority were able to generate second-degree influence and elicit compliance from the higher-status professionals.

The relevance of the study is determined by the features of urban space management: the tendency to self-organization of the city is accompanied by the participation of citizens in the processes of transforming the urban environment. The article discusses the features of the process of involving citizens in changing the urban environment; the aim of the study is to build a typology of citizen participation in the development of urban space. Particular attention is paid to the issues of interaction and harmonization of interests of municipal authorities and city residents. The research methodology is based on the principles of social constructivism and phenomenology, with the help of which it was possible to identify the motives and types of citizen participation in the development of urban space. The main results were the identification of the main ways of citizen participation in changing the city - active and passive, as well as building a typology of residents according to their degree of participation and interest in the development of urban space. Three main types were identified - detached, interested, decisive. In general, we can talk about the predominance of passive forms of citizen participation in the life of the city, as well as the actualization of the problem of civic activity: the emergence and active spread of online forms of civic activity makes us take a new look at the usual traditional offline forms.

This study introduces consumer socialization agency (CSA; i.e. the act of influencing another about consumption) as the reason why consumers learn through peer communication on social media tourism sites. Based on an online panel of 193 US consumers, the study investigated how a personal connection to a tourism site (i.e. customer engagement [CE]) and a connection with peers on social media (i.e. peer group identification) drives CSA about tourism, which, subsequently, influences learning about tourism-related consumption decisions (i.e. peer communication). Our model establishes that identification with peers on social media and CE with tourism sites are antecedents to consumer socialization. Consumers need to feel engaged with tourism social media sites to participate in socialization and feel connected to their peers on social media in general. Consumer socialization, or the willingness to teach/influence tourism-related skills to friends, influences the willingness to learn new tourism consumer skills, including tourism-related decision-making. We propose that for a tourism site to be successful, it must enable social exchange of knowledge and ideas (through enabling consumer socialization), not just individual user experience.
