The pace of booking is a critical element in the accuracy of revenue management (RM) systems. Anecdotal evidence suggests that booking windows exhibit persistent shifts due to a variety of macro and micro factors. The article outlines several causes and tests the impact of the shifts on forecasting accuracy.

A novel methodological approach is utilized to empirically shift hotel reservation windows into smaller increments. Forecasts are then estimated and tested on the incremental shifts with popular RM techniques characteristic of advance booking data. A random effects model assesses the impact of the shifts on forecast accuracy.

The results show that shifts in booking behavior can cause the accuracy of forecasting models to deteriorate. The findings stress the importance of considering these shifts in model estimation and evaluation.

The results demonstrate that changes in booking behavior can be detrimental to the accuracy of RM forecasting algorithms. It is recommended that revenue managers monitor booking window shifts when forecasting with advanced booking data.

This study is the first to systematically assess the impact of booking window shifts on forecasting accuracy. The demonstrated approach can be implemented in future research to assess model accuracy as booking behavior changes.

Different from manufacturing resources allocation problems, the prices and amounts of limited public service resources could not be changed with the consumers’ requirements and social fairness is the most important objective for improving allocation efficiency. To measure social fairness reasonably, the purpose of this paper is fourfold: first, divide social fairness into longitudinal comparative fairness and crosswise comparative fairness, therefore providing their calculation formula and describing the comprehensive fair degree by using the interval numbers. Second, the comparison regulations of interval numbers are given and the corresponding features are also described. Third, an extension of VIKOR method is put forward for evaluating social fairness of different allocation alternatives with interval numbers. Finally, a numerical example illustrates the proposed method and clarifies the main results developed in the paper.

In this paper, the author depicts the social fair degree as an interval number, and thus proposes the comparison method between any two interval numbers. Based on the basis procedure of the VIKOR method, the paper proposes an extension of the fuzzy VIKOR method with the interval numbers to rank and select the compromise allocation alternatives. Finally, a numerical example illustrates the practicability of the proposed method.

The comparison of interval numbers is very important when the author evaluates the decision alternatives. Through analyzing the present comparison methods, the paper proposes the simple method of comparing the interval numbers, which can obtain the same results with the above two methods. The fuzzy VIKOR method, a popular multi-criteria decision-making method, focusses on ranking and selecting from a set of alternatives in a fuzzy environment. For the fuzzy value, the paper also proposes the extension of the VIKOR method to perform an evaluation and get the compromise alternatives.

According to the huge customers’ requirement, how to improve their social fair degree has become the focus in public service resources allocation, where the social fair degree may be a comprehensive concept which includes the fair degree compared with all the other allocation alternatives and the fair degree compared with the other small group under the same allocation alternative. In the paper, the author defines the above two types of fair degree and then depicts the comprehensive fair degree as their integration, which will be interval numbers.

EVERY method employed by librar ns to bring books to the notice of readers may be justified It is thus desirable to devote an occasional issue of THE LIBRARY WORLD to this attractive subject. Our writers take differing views, but there is always a single aim in their work: to bring right book and reader into acquaintance. We might have to meet the challenge, which indeed one of our writers implies, that such book display may deflect the Library from its original, rightful purpose. Until these terms are defined such a challenge is a begging of the question. Often we have mentioned the question, For what public is the public library working? Was it intended to serve as an auxiliary, and then an extension, of the official education system? It has always indeed been more and less than that. Our founders were able to argue that libraries would withdraw men from beer and ill‐company, but from the first they probably failed to do that, and made their appeal to the intelligent elements in the community. As they developed and public education waxed, there grew up an enormous literature, available in early years in small quantity, the aim of which was entertainment only, and there survived—there survives still—a notion which was based on an earlier conception of books, that to read was somehow educative and virtuous, whatever was read. Librarians hold this notion in some measure to‐day, although the recent success of twopenny libraries which are mainly devoted to the entertainment type of literature must have made them revise the view somewhat.

This chapter details a cultural relevance of text project in-service K-12 teachers engage in during their graduate literacy methods class. Through this project, teachers, who work with emergent bilinguals, learn how to select culturally relevant texts using a rubric. They read their selection with a student and reflect on the experience. Four important conclusions came from an analysis of the projects teachers carried out. Teachers found that their students made connections and were more engaged when reading culturally relevant books. Participants found the rubric helpful in identifying what they should look for in a culturally relevant text. In addition, through this project, the teachers discovered that their libraries tended to lack culturally relevant literature. Finally, participant teachers learned more about their emergent bilingual students through the process of finding and reading culturally relevant stories. While this project was carried out by a limited number of teachers in urban environments, it has implications for teachers of emergent bilingual students in other contexts.

Contemporary adult readers' advisory aims to adhere to (what I term) a pure preference satisfaction model in which librarians provide nonjudgmental book recommendations that satisfy their patrons' aesthetic tastes rather than improve upon them. The purpose of this paper is to determine whether readers' advisors really ought to treat all such tastes as essentially benign, even when doing so may conflict with core commitments to diversity and social responsibility.

This paper utilizes a thought experiment to interrogate our intuitions regarding the practice of recommending recreational materials featuring marginalized protagonists. The author also draws on theoretical insights from feminist aesthetician A.W. Eaton's innovative work on taste in bodies to formulate argumentation addressing the ethical dilemma presented here.

Our reading tastes can, in fact, be oppressive, working to maintain unjust power relations that are often thought to be the product merely of bad beliefs. On the view advanced here, oppressive tastes function as real obstacles to collective self-governance because they systematically distort our judgments of the credibility, empathic accessibility, and fundamental worth of our fellow democratic citizens. Librarians' obligation to protect and promote democracy, therefore, provides practitioners with a crucial justification for recommending diverse books to all readers, even (and perhaps especially) those who actively disprefer them.

The paper illustrates how contemporary work in analytic (and specifically feminist) aesthetics can furnish LIS scholars with the intellectual resources to resolve political problems in the library. The author's analysis also lays the groundwork for further consideration of alternative ideals for readers' advisory that will capitalize on the service's educative and emancipatory potential.

Although the functional benefits of e-books have been discussed in the emerging literature on the e-reader platform, the hedonic/emotional aspects of e-book usage have not been explored. This study aims to explore the impact that e-readers have on consumers’ connections with books. Relying on self-concept theory and possessions as the extended self, the authors address the following two questions: What are the hedonic differences between e-books and printed books, and, if the functional benefits of e-books are so compelling, then why do some people still use printed books?

The researchers pursue a qualitative design through the use of semi-structured interviews, with a combination of base questions and follow-up questions tailored to the individual respondent.

The results reveal six primary themes: convenience, change, community, collection, connection and children. Within each, functional benefits are identified, confirming prior literature on these benefits, and hedonic/emotional themes emerge, revealing that e-readers are capable of changing consumers’ connections with books. Namely, while e-books offer functional benefits over printed books, consumers feel less connected to books read using an e-reader platform and prefer to purchase the printed versions of books that hold special meanings for them. These findings align with self-concept theory and indicate that printed books are an extension of the self, one that cannot be completely replaced by e-books.

This research adds to the emerging literature on e-books by demonstrating that e-readers have emotional implications for consumers as components of the self-concept/extended self. Prior literature has focused solely on the functional benefits associated with e-books but has not directly addressed the role of books in the self-concept.

The purpose of this paper is to illustrate issues surrounding the Google Book settlement in 2009, and its relevance to libraries by general discussion and examples from library practice.

A set of projections and speculations that are both conceptual and practical in nature, based on early reactions and comments about this development.

There are many philosophical and moral objections to the consequences of the Google Book settlement, and that the practical effects for academic libraries could be both positive and/or negative. The practical examples of such outcomes are designed to help clarify the implications for library and information practitioners and generate further debate.

The fact that the Book settlement is a legal arrangement between parties in a civil court makes in depth research analysis of a public nature very difficult – which is in itself one of the main themes of the paper.

The teasing out of the real‐life consequences of the settlement are intended be helpful to the library practitioner.

This paper tries to offer an early insight into an important new development in information retrieval history from the point of view of academic librarians, in contrast to much contemporary comment, which has come from authors and rights holders.

THE Library Association has begun the Centenary of the Public Libraries Acts' celebrations with an attractive booklet which, we suppose, is now in the hands of many, if not most, of our readers. We are to have, we understand, an official, documented history which should be worthy of the occasion; that may come later. The booklet, however, A Century of Public Library Service, should be made available in every library. To be effective it should go into every household—a manifest impossibility on any means at the command of the Library Association, since the booklet itself puts the registered borrowers alone at twelve millions, and if there are five people to a household, nearly two and a half million copies would be required. If it goes to every service point that will involve 23,000. These figures illustrate the difficulties of our publicity. The machine is too vast for all its parts to be reached. We suppose it will go to every librarian and every member of a library committee—about 6,000 copies—and that may be a good plan, although that would be sending it to those who are, we hope, converted. As for the book itself, it follows the lines of the paper read by Mr. L. R. McColvin at Eastbourne last year; it tells our history; shows by graph and figure the vast increase in supply to meet demand; deals successively with the various parts of the service; and surveys the future. Its value is as an assessment of book stock, staff and relative success and failure and the relation of these to the resources, financial and otherwise, of libraries. In 1949 we are spending £1,650,000 on books, if our calculation at 2s. 9d. per borrower is correct. This, for the whole population—say 45 millions—is not lavish. These and many other useful points are indicated. The work is for domestic consumption, to serve as a basis for self‐examination. On the physical side it is attractive, is printed on plate paper, which brings out brightly the twenty‐five illustrations and a graph, which show pleasant samples of libraries and readers. As a curious point we find no sign in any of the pictures that there are men librarians in public libraries.

This paper aims to improve the accuracy of hotel daily occupancy forecasts – an essential element in the revenue management cycle – by proposing and testing a novel approach. The authors add the hotel competitive-set’s predicted occupancy as an input of the individual property forecast and, using a recursive approach, demonstrate that there is a potential for significant reduction in the forecasting error.

The paper outlines the theoretical justification and the mechanism for this new approach. It applies a simulation for exploring the potential to improve the accuracy of the hotel’s daily occupancy forecasts, as well as analysis of data from a field study of two hotel clusters’ daily forecasts to provide empirical support to the procedure’s viability.

The results provide strong support to the notion that the accuracy could be enhanced. Incorporating the competitive set prediction by using either a genetic algorithm or the simple linear regression model improves the accuracy of the forecast using either the absolute or the absolute percentage as the error measure.

The proliferation of data sharing practices in the hotel industry reveals that the timely data sharing-aggregation-dissemination mechanism required for implementing this forecasting paradigm is feasible.

Given the crucial role of accurate forecasts in revenue management and recent changes in the hotels’ operating environment which made it harder to achieve or maintain high levels of accuracy, this study’s proposed novel approach has the potential to make a unique contribution in the realm of forecasting daily occupancies.
