Purpose – The purpose of this paper is to put forward a Ultra-high Frequency Radio Frequency Identification (UHF-RFID) data model construction scheme for university libraries, hoping to realize the opening, uniform, compatible and interoperable RFID application between different libraries and manufacturers. Design/methodology/approach – This article uses the practical application needs of university libraries as the starting point, and proposes the UHF-RFID data model construction scheme for university libraries based on the study of applicable standards, such as ISO 28560. Findings – Based on practical application demand of university libraries and some international standards, the paper puts forward an UHF-RFID data model construction scheme for university libraries. First, the scheme explains and defines six user data elements different from ISO28560: version, owner library identifiers, temporary item location, subject, International Standard Serial Number (ISSN) and International Standard Book Number (ISBN). Furthermore, different encoding rules for electronic product code (EPC) data area and user data area are designed to achieve maximum work efficiency. Practical implications – This paper tries to bring forward a set of referential UHF-RFID data model standards for university libraries. Hopefully, this standard will offer uniform data models for university libraries to comply with, integrate the disordered market and further make the opening, unified, compatible and interoperable RFID application possible. Originality/value – Although there are several formally published RFID standard documents, they are primarily designed for high frequency RFID technology. Concerning UHF-RFID technology, there are still no internationally unified data model standards. Hence, this paper brings forward the UHF-RFID data model construction scheme for university libraries.
FEATUREcustomers requires not only traditional "reference" skills, but also skills that reflect adaptability, strong communication, customer service, technology support, and training.2 Librarians at George Mason University Library further put forward that the basic qualities a competent librarian is expected to have should include: "commitment to developing, providing and maintaining high quality services and programs, valuing knowledge, and life-long learning, fostering collaboration and teamwork, engagement in professional development, an enterprising spirit reflecting flexibility, adaptability, intellectual curiosity, creativity, initiative, persistence, excellent communication and instructional skills, time management and organizational skills." 3 These features summarize the required capabilities of liaison librarians well.Due to stringent requirements set for subject librarians, many professionals stress librarian literacy training. Krasulski gives some advice, including ways the access services community can act to fill the gap left by the absence of training opportunities in library and information science graduate programs. 4 Luo' s study suggests content design opportunities for text reference training and education to help improve service performance.5 Cassella et al. point out that academic programs should be developed to include communication, project management, and team work skills and lay more emphasis on copyright issues. The study also indicates that repository managers will have to spend a lot of time on professional training and self-directed learning.6 Todorinova et al. review standards for reference training in academic libraries with a focus on "one-desk service points" and think about best practices for planning, implementing, and evaluating training programs for librarians. 7 China, however, lacks professional qualification certificate systems for librarians and pertinent and systematic librarian training programs as well. In comparison with United States and United Kingdom university libraries, both the qualification requirements of the occupation and the subject service content in China' s university libraries are "left behind." 8 Many university librarians in China do not have library school education or librarian information literacy training, and this influences their ability to offer high quality subject services. 9 The libraries lack talented liaisons with strong academic backgrounds, advanced professional proficiency, and rapid adaptability. According to a survey of 62 librarians coming from 34 university libraries located in different regions of China participating in Project 985 (a project for funding world-class universities in the 21st century conducted by the government of the People' s Republic of China), 65 percent of the librarians have less than two years work experience in subject services, despite the fact 69 percent of them are subject liaisons. These statistics show that even in Project 985 university libraries, subject service is still in the exploratory stage and t...
Soil washing is an effective approach to remove soil heavy metals, and the washing agent is generally regarded as one of the primary factors in the process, but there is still a lack of efficient and eco-friendly agents for this technique. Here, we showed that four plant washing agents-from water extracts of Coriaria nepalensis (CN), Clematis brevicaudata (CB), Pistacia weinmannifolia (PW), and Ricinus communis (RC)-could be feasible agents for the removal of soil lead (Pb), zinc (Zn), and cadmium (Cd). The metal removal efficiencies of the agents increased with their concentrations from 20 to 80 g L, decreased with the increasing solution pH, and presented different trends with the reaction time increasing. CN among the four agents had the highest removal efficiencies of soil Pb (62.02%) and Zn (29.18%) but owned the relatively low Cd removal efficiencies (21.59%). The Fourier transform infrared spectroscopy showed that the abilities of plant washing agents for the removal of soil heavy metals may result from bioactive substances with specific functional groups such as -COOH, -NH, and -OH. Our study provided CN as the best washing agents for the remediation of contaminated soil by heavy metals.
PurposeThis paper aims to analyze the effectiveness of the subject librarian literacy training and put forward suggestions for the improvement of the subject librarian literacy training based on the satisfaction degree survey for the CALIS III Subject Librarian Literacy Training.Design/methodology/approachOn the basis of the satisfaction degree survey for the CALIS III Subject Librarian Literacy Training, this paper elaborates on the design of the survey, analyzes effectiveness of the training according to the survey results, and further advances suggestions for the enhancement of the subject librarian literacy training.FindingsAs an essential part of the library user service, subject services are highly demanding of subject librarians' literacy and capabilities. The subject librarians should thus own great abilities to be qualified for the innovative subject service work. Although the CALIS III Librarian Literacy Training and Qualification Certification Program, a vital executive program, has made great achievements, the training still needs to be further improved concerning the schedules, teaching atmosphere, training forms, training content, etc., to enhance the subject librarians' ability, raise the service standards and promote the fast and sound development of librarianship in China.Originality/valueThis paper offers detailed information on how to design a satisfaction degree survey for the subject librarian literacy training, analyzes the effectiveness of the librarian literacy training, and finally makes suggestions for the enhancement of the subject librarian literacy training.
