Object traceability based on Radio Frequency Identification(RFID)is an important capability of the Internet of Things(IoT).GS1 EPCglobal,a de-facto standard in RFID technology,develops Electronic Product Code(EPC)network architecture,which mainly includes EPC Information Service(EPCIS),Object Name Service(ONS),and Discovery Service(DS).This architecture is used to capture and share standardized events representing various aspects on EPC object.However,the EPC network architecture also faces challenges;for example,the separate management of unrelated event data and master data may increase time consumption when an application extracts valuable information by combing them.A Hardware-Based Information Service(HIS)device is raised in this paper,which is installed on the specific EPC tagged object directly and this could alleviate the problem above.The HIS could store the event data and master data related to the EPC identifier centrally and the application could gain the basic information based on the data stored in the HIS without utilizing ONS,DS and EPCIS. 展开更多

Purpose:The purpose of this paper is to explore how libraries can develop service and product strategies and the service support mechanism to provide industrial technology information service in science parks.Design/methodology/approach:The analysis is based on a case study of a large Chinese research library,National Science Library(NSL),the Chinese Academy of Sciences(CAS),in serving high-tech companies in Zhongguancun Science Park(Z-Park).Findings:NSL’s practices suggested that in serving business clients,libraries’ product and service strategies should be based on the understanding of users’ needs.Aside from those services that have been recognized by clients such as document retrieval & delivery and novelty search,libraries may expand their service and provide in-depth information analysis and consultation for some key clients.Moreover,a service and product development system should be established,which differentiates the libraries’ products and services from those of their competitors.In providing industrial technology information service,libraries need to construct the service support mechanism,publicize their service and learn to cooperate with clients to meet their demands for knowledge management and innovation.Research limitations:The generalizability of the findings is limited because they are based on an individual case study.Practical implications:Our service practices provide useful information for other libraries to expand their information service to high-tech companies in the new information environment.Originality/value:Z-Park is the first and one of the largest science and technology parks in China.Hence NSL’s practices in serving high-tech companies in Z-Park can be valuable to other libraries that intend to take up the similar service. 展开更多

Small-scale farming accounts for 78% of total agricultural production in Kenya and contributes to 23.5% of the country’s GDP. Their crop production activities are mostly rainfed subsistence with any surplus being sold to bring in some income. Timely decisions on farm practices such as farm preparation and planting are critical determinants of the seasonal outcomes. In Kenya, most small-scale farmers have no reliable source of information that would help them make timely and accurate decisions. County governments have extension officers who are mandated with giving farmers advisory services to farmers but they are not able to reach most farmers due to facilitation constraints. The mode and format of sharing information is also critical since it’s important to ensure that it’s timely, well-understood and usable. This study sought to assess access to geospatial derived and other crop production information by farmers in four selected counties of Kenya. Specific objectives were to determine the profile of small-scale farmers in terms of age, education and farm size;to determine the type of information that is made available to them by County and Sub-County extension officers including the format and mode of provision;and to determine if the information provided was useful in terms of accuracy, timeliness and adequacy. The results indicated that over 80% of the farmers were over 35 years of age and over 56% were male. Majority had attained primary education (34%) or secondary education (29%) and most farmers in all the counties grew maize (71%). Notably, fellow farmers were a source of information (71%) with the frequency of sharing information being mostly seasonal (37%) and when information was available (43%). Over 66% of interviewed farmers indicating that they faced challenges while using provided information. The results from the study are insightful and helpful in determining effective ways of providing farmers with useful information to ensure maximum benefits. 展开更多
