- Abstract
- In this research study, Nemertes performed an independent in-depth analysis of Internet and IP infrastructure (which we call capacity) and current and projected traffic (which we call demand) with the goal of understanding how each has changed over time, and determining if there will ever be a point at which demand exceeds capacity. To assess infrastructure capacity, we reviewed details of carrier expenditures and vendor revenues, and compared these against market research studies. To compute demand, we took a unique approach: Instead of modeling user behavior based on measuring the application portfolios that users had currently deployed, and projecting deployment of those applications in future, we looked directly at how user consumption of available bandwidth has changed over time.

- Abstract
- Accurate demand forecasting plays a critical role in hotel revenue management. Online reviews have emerged as a viable information source for hotel demand forecasting. However, existing hotel demand forecasting studies leverage only sentiment information from online reviews, leading to capturing insufficient information. Furthermore, prevailing hotel demand forecasting methods either lack explainability or fail to capture local correlations within sequences. In this study, we (1) propose a comprehensive framework consisting of four components: expertise, sentiment, popularity, and novelty (ESPN framework), to investigate the impact of online reviews on hotel demand forecasting; (2) propose a novel dual attention-based long short-term memory convolutional neural network (DA-LSTM-CNN) model to optimize the model effectiveness. We collected online review data from Ctrip.com to evaluate our proposed ESPN framework and DA-LSTM-CNN model. The empirical results show that incorporating features derived from the ESPN improves forecasting accuracy and our DA-LSTM-CNN significantly outperforms the state-of-the-art models. Further, we use a case study to illustrate the explainability of the DA-LSTM-CNN, which could guide future setups for hotel demand forecasting systems. We discuss how stakeholders can benefit from our proposed ESPN framework and DA-LSTM-CNN model.

- Abstract
- The evolution of education from supply driven (what the institution offers) towards demand driven (what the student wants) needs to be understood in the larger context of societal, economic, political, scientific and technological developments. Supply driven education is currently reinforced by the small set of available 'technologies'. The central ideas of new education theorists focusing on demand driven education seem to get realized thanks to a combination of emerging information technology provisions and new didactic insights into their use. Open University of the Netherlands where this type of education is being developed and implemented, are presented

- Telephone reference service at the California Univ. at San Diego Central Library hab become problematic in recent years due to increased volume of patron demand, both in person and on the telephone. In order to meet the demand the library established a separate information desk service which became the first line of service for incoming telephone callers. Reports a survey conducted in 1991 by information and reference desk staff to see how well this arrangement was meeting the needs of primary patrons. Details steps taken to correct shortcomings

- The Royal Institute of Technology (RIMT) Libraries developed and made available a HyperCard-based directional information system in the first semester of 1992. This was part of a strategy to relieve pressure on a very busy service point, the information desk. Discusses the features of the system and evaluates its impact upon the demand for information at the service point. While popular with students as a source of information, Qjumper has not stemmed the increasing demand placed upon the information desk

- Abstract
- Follows up the common assertion that consumer services will be the major driving force for the information superhighway by discussing the social and political factors likely to influence the rate of progress and the role of major consumer entertainment and information applications. Considers the trends in interactive television and system requirements for 'movies on demand', particularly in university department. Concludes that successful services offered at a price leading to mass demand will be slow in arriving

- Abstract
- eBooks on Demand (EOD) ist ein europaweites Netzwerk von mehr als 30 Bibliotheken in 12 europäischen Ländern mit dem Ziel, urheberrechtsfreie Bücher auf Anfrage zu digitalisieren und zur Verfügung zu stellen. Zur Digitalisierung kann jedes Buch bestellt werden, das im Online-Katalog der Bibliothek mit dem sog. EOD-Button versehen ist. Das so bestellte Buch wird dann innerhalb weniger Tage hochauflösend gescannt und nach erfolgreicher Bezahlung als PDF mit hinterlegtem OCR-Text zur Verfügung gestellt. Bisher musste in jedem einzelnen Katalog jeder teilnehmenden Bibliothek separat gesucht werden, um ein bestimmtes Buch zu finden. Seit Ende 2010 wird nun unter der Adresse http://search.books2ebooks.eu eine bibliotheksübergreifende Suchmaschine angeboten, die mit der Open Source Software VuFind realisiert wurde. Derzeit werden hier 1,8 Mio. Datensätze von 12 Bibliotheken durchsuchbar gemacht. Den NutzerInnen der bibliotheksübergreifenden Suchmaschine wird so schnell und unkompliziert Zugang zu bereits digitalisierten Werken als auch Büchern, die zur Digitalisierung auf Anfrage zur Verfügung stehen, gegeben.

- Abstract
- The increasing availabiblity of information published on CD-ROMs has created a demand for easier access to this information. To meet this demand many organizations are using local area networks (LANs), but this does not meet the needs of those who need remote access. These needs can be met by a specially designed information server that can support clients over lower bandwidth networks. This information server is based on the Wide Area Information Server (WAIS) software for Z39.50 to provide access for clients running on PCs, Macintosh systems and UNIX systems. Although this protocol is not ideally suited for this purpose, it offers the possibility of a common protocol for accessing a variety of information sources, not just CD-ROMs

- Abstract
- Advances in storage and networking technologies will enable the construction of multimedia-on-demand information services capable of providing services over metropolitan area networks similar to those of a neighbourhood videotape rental store. Describes feedback techniques for supporting continuous and synchronuous retrieval from multimedia servers. Presents methodes to determine the minimum rate at which feedback units must be tramsmitted to maintain continuity and synchronization. The techniques remain robust in the presence of playback rate mismatches and network delay jitter. A feedback rate of 1 per 1.000 media units keeps the asynchrony within 250 ms. This work forms the basis of a prototype on-demand information serveer being developed at the University of California at San Diego

- Abstract
- Retrieval techniques may be based on the full text of documents, or on descriptors selected from a thesaurus. The latter approach constitutes an attempt to bridge the gap between demand and documents, which causes problems if demand cannot be forecast. Building up a thesaurus involves choosing the method of collecting descriptors, choosing the actual descriptors and making the system easily accessible to users. Classification and a classified catalogue are essential to the organisation of knowledge. Rules for the formation of classes have developed out of natural systems of classification. Chain indexing greatly aids the formation of the subject index. UDC and DDC are used in most documentation centres in the Netherlands. Public libraries mostly use SISO, a Dutch universal classification system

- Abstract
- The main purpose of this article is to explore the determinants of book borrowing demand from local public libraries in Norway, using balanced panel data for the period 2001-2004. The more striking results of these calculations show the basic differences between children and adults in the effects of main borrowing determinants. While income is quite important and the shadow price is quite unimportant for children, the opposite is true for adults. A likely explanation of this finding is that the real shadow price is higher for adults and that it is also higher in communities with high income levels. It was found that both stock and growth of the stock are important factors for book loans as well as loans of other media. There is a basic difference, however, in the effect of books on the demand for other media as compared with the opposite cross-effect: The book stock has a substantial and significantly negative impact on the demand for other media. The face value of this finding implies that there is actually a crowding-out effect on other media from books, while it is usually expected to be the other way around.
