From Offshore Operation to Onshore Simulator: Using Visualized Ethnographic Outcomes to Work with Systems Developers

This paper focuses on the process of translating insights from a Computer Supported Cooperative Work (CSCW)-based study, conducted on a vessel at sea, into a model that can assist systems developers working with simulators, which are used by vessel operators for training purposes on land. That is, the empirical study at sea brought about rich insights into cooperation, which is important for systems developers to know about and consider in their designs. In the paper, we establish a model that primarily consists of a ‘computational artifact’. The model is designed to support researchers working with systems developers. Drawing on marine examples, we focus on the translation process and investigate how the model serves to visualize work activities; how it addresses relations between technical and computational artifacts, as well as between functions in technical systems and functionalities in cooperative systems. In turn, we link design back to fieldwork studies

Contract Farming for Better Farmer-Enterprise Partnerships: ADB\u27s Experience in the People\u27s Republic of China

[Excerpt] Agriculture should provide safe and nutritious food to people. In the People’s Republic of China (PRC ) and many other developing members of the Asian Development Bank (ADB), agriculture is also the main source of income for rural residents. Yet as compared with the total labor force absorption, the contribution of agriculture to gross domestic product is very small, suggesting lower productivity, often resulting in poverty. Recognizing the invaluable contribution of agriculture to the PRC ’s development, the government has been prioritizing agricultural modernization in its policy agenda with an aim to further improve the agricultural sector’s productivity and efficiency. ADB’s support to the sustainable development of agriculture in the PRC covers broad areas ranging from irrigation infrastructure and farmland upgrading to agribusiness development and food safety. The Dryland Sustainable Agriculture project commenced in 2009 with ADB assistance supports the development of partnerships between private agro-enterprises and farmers using contract farming arrangements to strengthen farm productivity, food production, and processing capacity in 27 counties in Gansu, Henan, and Shandong provinces. After 6 years, the project has delivered considerable amount of outputs in terms of facilities established and farmers engaged, showing promise in achieving its outcome. Concurring with the request from the Ministry of Agriculture, the project executing agency, ADB provided a grant to study the experiences arising from the project with respect to developing sustainable farmer–enterprise partnerships particularly contract farming models. Equally important, the study examines the issues involved in current contract farming practices and recommends policies that may help resolve them

Incorporating prediction models in the SelfLet framework: a plugin approach

A complex pervasive system is typically composed of many cooperating \emph{nodes}, running on machines with different capabilities, and pervasively distributed across the environment. These systems pose several new challenges such as the need for the nodes to manage autonomously and dynamically in order to adapt to changes detected in the environment. To address the above issue, a number of autonomic frameworks has been proposed. These usually offer either predefined self-management policies or programmatic mechanisms for creating new policies at design time. From a more theoretical perspective, some works propose the adoption of prediction models as a way to anticipate the evolution of the system and to make timely decisions. In this context, our aim is to experiment with the integration of prediction models within a specific autonomic framework in order to assess the feasibility of such integration in a setting where the characteristics of dynamicity, decentralization, and cooperation among nodes are important. We extend an existing infrastructure called \emph{SelfLets} in order to make it ready to host various prediction models that can be dynamically plugged and unplugged in the various component nodes, thus enabling a wide range of predictions to be performed. Also, we show in a simple example how the system works when adopting a specific prediction model from the literature

DIGITAL TEHNOLOGIES. AN OVERVIEW OF CURRENT EVOLUTIONS AND IMPACT

Various observers describe today's global economy as one in transition to aknowledge economy, as an extension of an information society. The transition requires thatthe rules and practices that determined success in the industrial economy need rewriting in aninterconnected, globalized economy where knowledge resources such as know-how andexpertise are as critical as other economic resources. According to analysts of the knowledgeeconomy, these rules need to be rewritten at the levels of firms and industries in terms ofknowledge management and at the level of public policy as knowledge policy or knowledge-related policy. The digital and ICT revolutions are twin revolutions. Information andcommunications technology (ICT) refers to a broad field encompassing computers,communications equipment and the services associated with them. It includes the telephone,cellular networks, satellite communication, broadcasting media and other forms ofcommunication.digital revolutions, communication equipment, broadcasting media

Encourage. Empowering People. Annual Report 2012

Peter Löscher, President of the Siemens Stiftung Board of Trustees, on behalf of the Board: Siemens Stiftung aims to contribute to positive changes in society with technical solutions, concrete concepts, and platforms for knowledge transfer. Cooperating with various stakeholders is a fundamental requirement for increasing the impact of its projects and anchoring them for the long term. For that reason, Siemens Stiftung seeks to cooperate with other foundations and non-governmental organizations as well as with government institutions, businesses, and the scientific community. Partnerships allow complementary approaches, skills, and resources to be bundled and sustainable programs to be developed. The previous fiscal year, in particular, delivers impressive examples of how such partnership models can increase the effectiveness of project work

With the development of the industry and society, new verticals have emerged, such as Industry 4.0, cooperative sensing and augmented reality. These verticals require network robustness and availability, which forces the use of distributed domains to improve network scalability and resilience. To this aim, this paper proposes a new solution to distribute SDN domains by using Data Distribution Services (DDS). The DDS allows the exchange of network information, synchronization among controllers and auto-discovery. Moreover, it increases the control plane robustness, an important characteristic in 5G networks (e.g., if a controller fails, its resources and devices can be managed by other controllers in a short amount of time as they already know this information). To verify the effectiveness of the DDS, we design a testbed by integrating the DDS in SDN controllers and deploying these controllers in different regions of Spain. The communication among the controllers was evaluated in terms of latency and overhead.Postprint (author's final draft

Management of e-technology in China

"e" technology is bringing about many challenges for companies, in particular for their managers. This concerns a vast range of business processes in many sectors of the economy and in nearly every country of the world. In rapidly industrializing China, companies and other organizations are actively finding their way by adapting, developing and exploiting new e-technologies. The paper's focus is the identification of the management issues in implementing e-technology in China. The paper reports on research into difficulties of establishing and operating e-business in China. In particular, it discusses management related to e-technology sharing and application. A brief review of literature is followed by the analysis of three recent case studies: an international IT services alliance, a financial services provider and an international manufacturing joint venture. All case companies are applying e-technology in China, but the role of e-technology differs in the three cases: adding a service line to the existing business processes; developing a new business process; and increasing efficiency and effectiveness in business processes. The conclusions present the emerging management issues: cooperation is a key asset in networking; the choice of business models plays an important role; adequate management attention for details such as a training program is require
