Imagine, if you will, that the year 2010 has arrived, and that many of the wonderful things that librarians worked so hard for in the last half of the twentieth century have come to pass. Libraries of all types, large and small, are linked through a network of automated systems, providing total bibliographic access to the holdings of every library. Better still, patrons now receive items in hours or days through a combination of telefacsimile and ultrafast delivery. To the users, each library has become a gateway to all resources held by all libraries, and library information services are “location transparent,” that is, the patron has little awareness of where a piece of information may in fact have come from—it may be from a library across the street or from one across the country.

All items listed may be borrowed from the Aslib Library, except those marked *, which may be consulted in the Library.

The purpose of this project is to test and, if necessary, refine a model of the public sphere known as the circulation of power model. The model faces several criticisms and was applied in a case study only once. It has not yet been applied to an American context.

This study uses the circulation of power model as a framework in a historical case study of a regional public library system in the United States. The temporal boundaries of the case are from 1924 to 2016.

This study resulted in a new and modified model called the tessellation model. New concepts in the tessellation model include circuits, tessellations, formal decisions and decision cycles. New distinctions in the model include narrowcast/broadcast and coalesced public/diffuse public.

The tessellation model and its associated concepts offer a new way to describe and analyze deliberative systems over time. The model requires further testing in other contexts.

The tessellation model is a new and validated way to describe the public sphere in an American political context.

The purpose of this study is to systematically examine the existing literature published on the circulation methods used in academic libraries and to discuss a proposed model for the self-check-in and check-out methods using quick response (QR) codes.

A systematic literature review (SLR) provided a complete overview of circulation systems used in academic libraries for the last more than 140 years. Preferred reporting items for systematic reviews and meta-analyses (PRISMA) method for SLR was used. Several databases such as ProQuest, Emerald, Library and Information Science Abstracts, EBSCO and Google Scholar were searched. Out of 277 papers retrieved in the search, 43 most relevant papers were taken up for the SLR. These were classified into four themes based on the systems of circulation used, namely, manual (5), mechanized (13), automated (5) and networked system (20). Based on the findings of the SLR, a model of circulation system in which QR code technology has been used.

The result of SLR identified 33 systems used in above mentioned four groups. Among this, a large number 48.48% of mechanized systems were found. Each system has limitations either because of devices used or of technology. The present study proposes a QR code-based model at the circulation desk, for which a prototype of Android app has been designed. This would help to initiate the new “self-services” facility to users at the circulation desk.

The proposed model, after its successful implementation, can be adopted by academic libraries. Guidelines and a graphical representation of this study can be used by any researcher for further experimentation.

To the best of the authors’ knowledge, this is the first kind of study in which a QR code-based Android app model has been proposed for library circulation records.

The purpose of this article is to describe the quantitative evaluation of an engineering monograph approval plan using circulation analysis.

The circulation frequency of titles purchased under the approval plan was analyzed, and compared with the circulation frequency of all engineering books during the same time period, purchased both individually and through the plan.

It was found that 23 percent of the approval plan books circulated, compared with 6 percent of engineering books as a whole. There was considerable variation in circulation frequency between engineering disciplines, but approval plan books circulated much more frequently in all subject areas.

This study assesses circulation only during the most recent complete year, which means that the approval plan books are all new books. However, more than half of the books in the engineering collection are less than ten years old, so age is unlikely to be the only reason for the much higher circulation of approval books.

Since this evaluation concludes that the approval plan does have value for Rowan University's users, such a plan might be worth considering by other academic libraries looking for a better way to obtain new engineering monographs which serve user needs.

While the circulation data described in this study reflect the unique needs of the Rowan University user community, they can serve as a useful benchmark for engineering librarians who want to assess the usage of their monograph collections. The study also has value for academic librarians who are evaluating an approval plan from YBP or another vendor.

The purpose is to explore the essential reasons for the differences between book awakening phenomena, to develop the critical factors in awakening the slumbering collections and to provide a reliable basis for maximizing book value and optimizing collection allocation.

The research employs the integrated learning algorithm XGBoost to measure driving factors. In the process of book circulation, the characteristics of collections and readers are worthy of attention. Therefore, this study also carries out feature selection and model construction from the two dimensions of books and readers.

The results show that reader features have a stronger impetus for the collection awakening phenomenon than collection features. Among reader features, education level, gender and major subject are the main factors, which are followed closely by the activity level; among collection features, publication date and price are the main driving factors. The indicators of book popularity are not significant, whose effect on the phenomenon of collection awakening is almost negligible.

This study aims to augment the theory of zero circulation from the theoretical level and, for the first time, seeks to define the phenomenon of collection awakening. This study attempts to present novel ideas for research in the field of libraries and to provide references for optimizing collection and maximizing the value of books.

The objective of this study is to investigate several issues related to particle circulation within the TFB, including exploring an appropriate method to quantify particle circulation time, the effects of different operational parameters on particle circulation time, and the relationship between particle mixing and particle circulation.

The computational fluid dynamics coupled with the discrete element method (CFD-DEM) is applied to investigate the particle circulation characteristics of a tapered fluidized bed (TFB). An approach for defining particle circulation, which accounts for the horizontal motion of each particle, is proposed to estimate particle circulation time.

It is found that the overall particle circulation in a TFB could be accelerated by increasing air velocity and wall inclination angle, while an increase in particle size and an increase in inter-particle cohesive forces decelerate particle circulation; the increase in the open area ratio of the central region of the air distributor would decelerate the particle circulation. Moreover, the particle circulation time and mixing rate are independent variables that describe the flow dynamics of particles from different perspectives.

A large part of fluidized beds in industrial applications can be classified as TFB. This study presents a numerical method to obtain detailed knowledge about particle circulation in a TFB, which is essential for the design, optimization, and control of related processes.

The particle circulation in a TFB is important but rarely investigated, and it is hard to be quantified using existing experimental approaches. The proposed numerical workflow reveals the characteristics of particle circulation from a particle-scale perspective.

To solve several “inorganic” problems generated recently by community development in China (e.g., waste of social resources, environmental pollution, and decreased economic energy efficiency), focus should be on improving the community traffic organic micro-circulation system. As a historic and mixed functional urban community, the micro-circulation system of Xi'an Railway Bureau exhibits representativeness and complexity. Based on existing research results and years of follow-up investigations, which concentrate on circulation patterns and inherent organic development requirements of the community traffic micro-circulation system, this paper builds an evaluation index system. Value function method was used to implement the index factor quantitative analysis and comprehensive evaluation. Several related strategies were proposed to improve the organic micro-circulation system of the community, which is based on the analysis of the evaluation, in order to adopt the trend in both increasing urban development and stock updating. The analysis results demonstrate that it is necessary to present guiding renewal strategies on community land, road, people, and the environment for those mixed functional communities which use progressive renewed mode. It compensates the problems of overly strong export-oriented system, which is caused by the lack of organic traffic micro-circulation, so as to achieve the selective opening of community external. The study mainly highlights the significance of the systematic analysis of evaluation in influencing strategies on community renewal.

As librarians consider adopting an automated circulation system, early tasks will be to 1) scan the literature, and 2) contact librarians who have already been involved in the process. The literature itself repeatedly urges the value of communicating with other libraries and librarians. For this purpose, most books on turnkey systems append a list of the systems and their installations in particular libraries.
