On proximity and hierarchy : exploring and modelling space using multilevel modelling and spatial econometrics

Spatial econometrics and also multilevel modelling techniques are increasingly part of the regional scientists‟ toolbox. Both approaches are used to model spatial autocorrelation in a wide variety of applications. However, it is not always clear on which basis researchers make a choice between spatial econometrics and spatial multilevel modelling. Therefore it is useful to compare both techniques. Spatial econometrics incorporates neighbouring areas into the model design; and thus interprets spatial proximity as defined in Tobler‟s first law of geography. On the other hand, multilevel modelling using geographical units takes a more hierarchical approach. In this case the first law of geography can be rephrased as „everything is related to everything else, but things in the same region are more related than things in different regions‟. The hierarchy (multilevel) and the proximity (spatial econometrics) approach are illustrated using Belgian mobility data and productivity data of European regions. One of the advantages of a multilevel model is that it can incorporate more than two levels (spatial scales). Another advantage is that a multilevel structure can easily reflect an administrative structure with different government levels. Spatial econometrics on the other hand works with a unique set of neighbours which has the advantage that there still is a relation between neighbouring municipalities separated by a regional boundary. The concept of distance can also more easily be incorporated in a spatial econometrics setting. Both spatial econometrics and spatial multilevel modelling proved to be valuable techniques in spatial research but more attention should go to the rationale why one of the two approaches is chosen. We conclude with some comments on models which make a combination of both techniques

An analysis for more equitable revenue and expenditure allocations within Lingnan College

From the triennial 1995-98, the funds allocated from University Grants Committee to universities have decreased. In order to use the limited resources effectively, and to manage their revenue and costs efficiently, universities have to set up a better budgeting system. Therefore, the eight universities in Hong Kong are proposing the Revenue Center Management (RCM) instead of the current budgeting system. The purposes of this project focuses on the analyses of the current budgeting system adopted at Lingnan College, and the proposed RCM budgeting system

The effects of size on local banks´ funding costs

Motivated by the recent discussion of the declining importance of deposits as banks´ major source of funding we investigate which factors determine funding costs at local banks. Using a panel data set of more than 800 German local savings and cooperative banks for the period from 1998 to 2004 we show that funding costs are not only driven by the relative share of comparatively cheap deposits of bank´s liabilities but among other factors especially by the size of the bank. In our empirical analysis we find strong and robust evidence that, ceteris paribus, smaller banks exhibit lower funding costs than larger banks suggesting that small banks are able to attract deposits more cheaply than their larger counterparts. We argue that this is the case because smaller banks interact more personally with customers, operate in customers´ geographic proximity and have longer and stronger relationships than larger banks and, hence, are able to charge higher prices for their services. Our finding of a strong influence of bank size on funding costs is also in an in- ternational context of great interest as mergers among small local banks - the key driver of bank growth - are a recent phenomenon not only in European banking that is expected to continue in the future. At the same time, net interest income remains by far the most important source of revenue for most local banks, accounting for approximately 70% of total operating revenues in the case of German local banks. The influence of size on funding costs is of strong economic relevance: our results suggest that an increase in size by 50%, for example, from EUR 500 million in total assets to EUR 750 million (exemplary for M&A transactions among local banks) increases funding costs, ceteris paribus, by approximately 18 basis points which relates to approx. 7% of banks´ average net interest margin

Marketing education, distance learning and hypermedia: teaching current issues in marketing in a virtual campus

This article reports on a project at the Universitat Oberta de Catalunya (UOC: The Open University of Catalonia, Barcelona) to develop an innovative package of hypermedia-based learning materials for a new course entitled 'Current Issues in Marketing'. The UOC is a distance university entirely based on a virtual campus. The learning materials project was undertaken in order to benefit from the advantages which new communication technologies offer to the teaching of marketing in distance education. The article reviews the main issues involved in incorporating new technologies in learning materials, the development of the learning materials, and their functioning within the hypermedia based virtual campus of the UOC. An empirical study is then carried out in order to evaluate the attitudes of students to the project. Finally, suggestions for improving similar projects in the future are put forward.Aquest article informa sobre un projecte de la Universitat Oberta de Catalunya per a desenvolupar un paquet innovador de materials didàctics hipermèdia basat en un nou curs titulat "Qüestions Actuals de Màrqueting". La UOC és una universitat a distància es basa íntegrament en un campus virtual. El projecte es va dur a terme els materials d'aprenentatge per tal de beneficiar-se dels avantatges que ofereixen les noves tecnologies de comunicació a l'ensenyament del màrqueting en l'educació a distància. L'article repassa els principals temes implicats en la incorporació de noves tecnologies en materials d'aprenentatge, el desenvolupament dels materials d'aprenentatge, i el seu funcionament dins del hipermèdia basat en el campus virtual de la UOC. Després s'ha portat a terme un estudi empíric per a avaluar les actituds dels estudiants del projecte. Finalment, es presenten suggeriments per a la millora de projectes similars en el futur.Este artículo informa sobre un proyecto de la Universitat Oberta de Catalunya para desarrollar un paquete innovador de materiales didácticos hipermedia basado en un nuevo curso titulado "Cuestiones Actuales de Marketing".

Drivers for wireless handheld technology: views from Queensland nurses

[Abstract]: The use of wireless hand held devices is becoming popular in healthcare due to its flexibility and mobility. In the nursing domain, the use of handheld devices, a specific component of wireles technology appears to be beneficial for data collection and other information management functions nurses may undertake. Studies in nursing literature have indicated that handheld devices deliver advantages and benefits at the point of care. In this study a set of 30 interviews with Queensland Nursing Staff in one district health centre was conducted over a period of three months to establish the drivers for the introduction of wireless technology among nurses. The outcome of these interviews is developed into a preliminary model and reported in this paper
